This research report presents a transdisciplinary student research project on the development of climate resilience of communities on the Caribbean Island Dominica. The research was conducted through a partnership between the Leuphana University Lüneburg and the Sustainable Marine Financing Programme (SMF) of the GIZ. For the GIZ, the research project aimed at improving the understanding of the socio-ecological resilience framework for tackling problems of Marine Managed Areas and Marine Protected Areas. Also, it enabled new thoughts on how the GIZ and other development agencies can more effectively assists island states to better cope with the challenges of climate change. The role of the students from the “Global Environmental and Sustainability Sciences” programme of Leuphana University included the design of four transdisciplinary research projects to research aspects of resilience of Caribbean communities. The developing island states in the Caribbean are extremely vulnerable to more frequent and intense natural hazards while relying on the ecosystem services that are also at risk from extreme weather events, in particular Hurricanes. Low economic stability leads to a dependency of the states on international assistance. To decrease the vulnerability to shocks, counteracting measures that encourage learning and adaptation can increase the resilience against extreme weather events and their consequences. Concepts that were considered during the design of the transdisciplinary research projects were the adaptation of systems, diversity and stakeholder participation and resilience-focused management systems. Also, the students critically assessed the concept of foreign aid and how it can be successful, mitigating the risk of introducing neo-colonial structures. Flood Management, Biodiversity, Small-Scale Agriculture and Foreign Aid on Dominica were the topics of the transdisciplinary projects. The research methods of a literature review, stakeholder mapping, interviews, scenario development and visioning were used in the projects. In four scenarios developed in the ‘Flood Management’ project, it became evident that a broad as well as coordinated stakeholder engagement and a variety of measures are required for community resilience. A key finding of the ‘Biodiversity’ project was the identity dimension of community resilience, underlining the importance of the relationship between individuals and nature. The interlinkage of social identity processes and a resilient disaster response was also stressed by the project ‘Foreign Aid’, which highlighted that financial support is similarly important to inclusivity and reflexivity in the process of resource distribution. To recover from extreme weather events, the social memory also plays an important role. The project on ‘Small-scale Agriculture’ concluded, that the memory-making of local communities is as vital to community resilience as formal plans and trainings. The research project was based on the research approach of transdisciplinarity because of its solution-orientation. It links different academic disciplines and concepts, and non-scientific stakeholders are included to find solutions for societal and related scientific problems. In the four projects, principles of transdisciplinary research were party applied, but some challenges arose due to the geographical distance, time constraints and a strong focus on the scientific part in some phases. Nonetheless, the findings of the projects provide valuable learning lessons to be applied in practice and that can prove useful for future research.

Der Ausbau der erneuerbaren Energien als Ausprägung des klimaschutzpolitischen Substitutionsansatzes wird in Deutschland mithilfe verschiedener Gesetze gesteuert. Dabei haben sich in mehr als 30 Jahren umfangreiche Regelungsstrukturen herausgebildet. Besonders ausgeprägt ist dies im Stromsektor zu beobachten. Hier kön-nen ausgehend vom Kartellrecht über den Zwischenschritt des Stromeinspeisungsgesetzes bis zu den verschie-denen Fassungen des Erneuerbare-Energien-Gesetzes vielfältige Entwicklungslinien anhand ausgewählter kon-kreter Veränderungen aufgezeigt werden. Sowohl im Hinblick auf Änderungsdynamik wie -tiefe deutlich weni-ger ausgeprägt sind dagegen die Entwicklungslinien im Wärmesektor. Diese nehmen ihren gesetzlichen Ur-sprung erst 2009 mit dem Erneuerbare-Energien-Wärmegesetz, um dann zusammen mit den gebäudebezoge-nen Effizienzregelungen 2020 infolge eines umfassenden rechtlichen Konsolidierungsschritts im Gebäudeener-giegesetz zu münden. Die Ausgestaltungsschritte im deutschen Erneuerbare-Energien-Recht sind auf vielfältige Weise mit den Ent-wicklungen im europäischen Rechtsrahmen zur Steuerung des Ausbaus der erneuerbaren Energien verwoben. Dies betrifft zunächst die Judikatur zu den primärrechtlichen Anforderungen an die Ausgestaltung mitglied-staatlicher Förderinstrumente, gilt aber besonders für die Entwicklungen im Sekundärrecht. Hier hat sich seit 2001 in mehreren Schritten eine immer detailliertere sekundärrechtliche Ordnung entwickelt. Dabei beinhalten die Entwicklungen der Erneuerbare-Energien-Richtlinien nicht nur eindimensional Steuerungs- und Bindungs-wirkungen von der supranationalen in Richtung der mitgliedstaatlichen Ebene. Vielmehr finden sich darin auch Entwicklungen zur Beschränkung der europarechtlichen Einflüsse, namentlich der Vorgaben zur Warenver-kehrsfreiheit und des Beihilferechts, die eine unmittelbare Reaktion der Mitgliedstaaten auf die Entscheidun-gen der europäischen Gerichte und der Europäischen Kommission darstellen. Das Erneuerbare-Energien-Recht ist zudem eingebettet in das übergreifende Umweltenergie- und Klima-schutzrecht. Mit der sowohl auf europäischer als auch deutscher Ebene im Werden befindlichen umfassenden Klimaschutzordnung lassen sich ebenso wie mit dem sich fortlaufend ändernden Instrumentenmix zahlreiche Wechselwirkungen feststellen. Der mit der neuen Klimaschutz-Governance geschaffene prozedurale Rahmen etabliert ein System von Klimaschutzzielen, Evaluierungs- und Nachsteuerungsvorgaben. Dieser ist aber mit dem Erneuerbare-Energien-Recht und dessen Zielen nur lose verbunden. Detaillierungsgrad und Steuerungs-wirkung der europäischen und der deutschen Klimaschutz-Governance unterscheiden sich dabei deutlich, was auch mit den stärkeren Koordinationsbedürfnissen im eher vertikal orientierten supranationalen Regelungs-verbund begründet ist. Dass die Entwicklung im Erneuerbare-Energien-Recht in absehbarer Zeit zu einem Endpunkt gelangen könnten, ist nicht zu erwarten. Dies wird deutlich, wenn die tatsächlichen Herausforderungen der Transformation und aktuell diskutierte Themenfelder für die weitere Fortschreibung dieses Rechtsbereichs betrachtet werden. Dabei sind die verschiedenen Dimensionen der Integration erneuerbarer Energien zur Vertiefung der System-transformation ebenso von Bedeutung, wie Regelungen zu Akzeptanz und Teilhabe sowie zur Beantwortung der Verteilungsfragen einerseits und eine Reduktion des Komplexitätsumfangs im Recht anderseits.

This doctoral thesis deals with the topic of organizational misconduct and covers the three salient research streams in this area by addressing its performance outcomes, antecedents, and preventive measures. Specifically, it is concerned with the question of how different forms of misconduct are reflected in the stock performance of related organizations, thereby, covering the three pillars of corporate sustainability environmental, social, and governance (ESG). Furthermore, it aims to conceptualize how individual cognitive biases may lead to misconduct, therefore, potentially representing an antecedent and how existing management control systems can be enhanced to effectively address specific forms of misconduct, respectively. To these ends, I first review the research stream of stock price reactions to environmental pollution events in terms of the underlying research samples, methodological specifications, and theoretical underpinnings. Based on the findings of the systematic literature review (SLR), I perform three stock-based event studies of the Volkswagen diesel emissions scandal (Dieselgate), workplace sexual harassment (#MeToo accusations), and the 2003 blackout in the US to cove the three ESG dimensions, respectively. In line with the SLR, my event studies reveal substantial stock losses to firms involved in misconduct that are eventually even accompanied by a spillover effect to uninvolved bystanders. Then, I review the extant literature conceptually to develop a framework outlining how moral licensing as an individual cognitive bias might lead to a self-attribution of corporate sustainability, a consecutive accumulation of moral credit, and a later exchange of this credit by engaging in misconduct afterward. Finally, I assess existing workplace sexual harassment management controls, such as awareness training and grievance procedures critically in another conceptual analysis. Based on the shortcomings stemming from management controls’ focus on compliance and negligence of moral duties, I introduce five specific nudges firms should consider to enhance their existing management controls and eventually prevent occurrences of workplace sexual harassment. Based on the six distinct articles within this doctoral thesis, I outline its limitations and point at directions for future research. These mainly address providing further evidence on the long-term performance effects of organizational misconduct, enriching our knowledge on further cognitive biases eventually leading to misconduct, and conceptualizing nudging beyond the use-case of workplace sexual harassment.

The way humans have shaped the world so far has led to various fundamental and complex problems that we are currently facing: climate change, biodiversity loss, pandemics. Transdisciplinary sustainability research addresses such complex problems by including a great variety of perspectives, forms of knowing and bodies of knowledge, including non-scientific ones, in the research process. Design, understood in an expanded sense as a creator of transformative processes, also turns to these ‘wicked problems’. Based on their common concern, it is promising to bring both fields of research together productively. Therefore, this dissertation seeks to better understand how design methods facilitate collaborative knowledge production and integration in inter- and transdisciplinary sustainability research. Through five independent papers, this dissertation contributes to addressing the research question on four levels – conceptual-epistemological, empirical, methodological and practical. By exploring the linkages between design research and inter- and transdisciplinary research, a conceptual basis for the targeted use of design methods in collaborative processes of inter- and transdisciplinary research is laid and their spectrum of methods is expanded. This is followed by the development of a transformative epistemology in and for problem-oriented, collaborative forms of research, such as transdisciplinary sustainability research, called problematic designing. Based on a deeper understanding of integration and collaborative knowledge production, as well as its accompanying challenges, empirical research into applying design prototyping as a method in and for situations of collaborative research was conducted. To this end, the findings provide a fundamental basis for the facilitation of inter- and transdisciplinary research processes when dealing with complex problems. With its inherent openness and iterative approach in addressing the unknowns of complex phenomena, design prototyping contributes to the required form of imagination that enables to anticipate possible futures. Furthermore, by including visual-haptic modes of expression, design prototyping reduces the dominance of language and text in scientific negotiation processes and does justice to the diversity of cognitive modes. Finally, the empirical findings of this dissertation emphasise the importance of the visual-haptic dimension for collaborative knowledge production and the communication of knowledge, and provide insights into the visual structuring of human thought processes. The results on material metaphors, collaborative prototyping and material-metaphorical imagery contribute decisively to the basic knowledge of the epistemological quality of design and the importance of the visual and haptic for thought processes in general. The extension and adaptation of existing analysis methods in this dissertation add to the further development of analysis of visual-haptic data. The results are once again reflected in the synthesis of this framework paper as cross-cutting issues. With developing design prototyping as a design-based intervention and its integration into the epistemological perspective of problematic designing for inter- and transdisciplinary sustainability research, this dissertation makes an important contribution to addressing complex future-related problems and to creating change towards sustainability.

Mit dem Ausbruch des neuartigen Corona-Virus Ende Dezember 2019 in der chinesischen Stadt Wuhan kam es innerhalb kürzester Zeit zur weltweiten Ausbreitung und in Folge zu einem pandemischen Notstand, welcher die Arbeitswelt nachhaltig verändern sollte. Weltweit verhängte Maßnahmen zur Eindämmung des Infektionsgeschehens führten zu massiven Einschränkungen des Alltags- und Berufslebens vieler Arbeitnehmer. Unternehmen sahen sich folglich dazu gezwungen, in kürzester Zeit schnelle und flexible Lösungsmöglichkeiten durch die Nutzung mobiler Arbeitsformen zu entwickeln, um den Geschäftsbetrieb aufrechtzuhalten. Für zahlreiche Beschäftigte wurde das Arbeiten von Zuhause damit kurzerhand zur neuen Realität, insbesondere im grenzüberschreitenden Bereich. Mehr als ein Drittel der Arbeitnehmer in Europa befanden sich im Zuge der Pandemie im Homeoffice. Vor allem im internationalen Bereich haben sich im Zuge dessen neue Arbeitsformen und Trends entwickelt. „Remote Work“, „Workation“3, „Digital Nomads“ oder etwa „Hybrid Working“ sind Begriffe, die durch die neue Flexibilität in der Arbeitswelt entstanden sind. Viele Unternehmen nehmen die Corona-Pandemie als Anlass dafür, ihren Beschäftigten auch in Zukunft weiterhin Möglichkeiten des flexiblen, ortsunabhängigen Arbeitens anzubieten. Einer Umfrage zufolge wollen etwa 77% der befragten Unternehmen auch nach der Krise mobiles Arbeiten ermöglichen.4 Insbesondere für internationale Mitarbeiter, die im Ausland wohnen und für ihren inländischen Arbeitgeber in Deutschland tätig werden, bietet mobiles Arbeiten neue flexible Möglichkeiten und Chancen Privat- und Berufsleben im Heimatland zu vereinen. Weitere Arbeitnehmer sehen hierin die Chance Arbeit und Urlaub zu vereinen, indem z.B. vom Ferienhaus aus in Dänemark gearbeitet wird. Internationale Auslandseinsätze sind in der Praxis allerdings mit einem hohen Regulierungsbedarf verbunden, da hierbei regelmäßig Fragestellungen im Hinblick auf steuerrechtliche, sozialversicherungsrechtliche als auch arbeitsrechtliche Aspekte zu klären sind, bevor eine solche grenzüberschreitende Tätigkeit rechtssicher erfolgen kann. Zu klären sind Fragen wie: Was ändert sich an der Steuerpflicht des Arbeitnehmers, sobald dieser einer Homeoffice-Tätigkeit im Ausland auf bestimmte Zeit für seinen inländischen Arbeitgeber nachgeht? Auf welcher Rechtsgrundlage kann mobiles Arbeiten im Ausland vereinbart werden? Was für Rahmenbedingungen sollten für eine solche Auslandstätigkeit festgehalten und entsprechend reguliert werden? Inwiefern ist der inländische Betriebsrat bei einer mobilen Auslandstätigkeit zu beteiligen? Die rechtlichen Risiken und Rechtsunsicherheiten bei einer grenzüberschreitenden Tätigkeit sind vielseitig und nicht zu unterschätzen. Zudem gibt es bislang noch keine eindeutigen rechtlichen Regelungen für mobiles Arbeiten im Ausland, sodass vorerst nur auf allgemeine Grundsätze zurückgegriffen werden kann.6 Unternehmen laufen damit schnell Gefahr, die Risiken, die im Hinblick auf mobiles Arbeiten im Ausland drohen, zu übersehen und Anfragen ihrer Mitarbeiter vorschnell, ohne sich mit den hiermit verbundenen rechtlichen Konsequenzen auseinanderzusetzen, zu genehmigen. Ziel dieser Thesis soll es sein, Arbeitgeber und ihre Mitarbeiter auf die Risiken von mobiler Arbeit im Ausland aufmerksam zu machen, ein Problembewusstsein für die gegenwärtigen Rechtsunsicherheiten zu schaffen und davon ausgehend Gestaltungsmöglichkeiten für einen rechtssicheren Umgang mit mobiler Arbeit im grenzüberschreitenden Bereich zu formulieren. Hierfür wird im Zuge der Arbeit ein Leitfaden zur rechtskonformen Ausgestaltung von mobiler Arbeit im Ausland konzipiert. Da der Umfang der Bachelorarbeit beschränkt ist, soll der Fokus im Rahmen dieser Thesis auf mobiler Arbeit im EU-Ausland liegen. In diesem Rahmen werden die Risiken im Hinblick auf ausgewählte steuerrechtliche sowie arbeitsrechtliche Fragestellungen herausgearbeitet.

The industrial food system is by far the largest greenhouse gas emitting sector. It causes significant damage to terrestrial, aerial and aquatic ecosystems, negative health impacts and an unfair distribution of economic benefits. The call for sustainability transformations is growing, entailing and promoting radical shifts in industrial food systems that lead to new patterns of interactions and balanced social, economic and ecological outcomes. While traditional research has focused on sustainability problems in the food system, it lacks evidence on solutions and desired future states; and more so, on how to practically move from the current to the desired state. Food forests present a promising solution to address multiple sustainability challenges adaptable to local contexts. As biodiverse multi-strata agroforestry systems, they can provide several ecological, socio-cultural and economic services. They sequester carbon, limit soil erosion and regulate the micro-climate; they offer the opportunity for education on healthy diets and ecology, and they produce food and can create livelihood opportunities. However, despite their obvious benefits and a trend in uptake, food forests are still a niche concept rarely known in mainstream culture. To date, research has focused on their ecological and social services; we lack an understanding of food forests as a comprehensive sustainability solution, including their economic dimension, and knowledge on how to develop them. Addressing these gaps, this qualitative research used a solution- and process-oriented methodology guided by transformational sustainability research. In a comparative case study approach, it created an inventory of 209 food forests, followed by interviews and site visits of 14 sites to understand their characteristics and assess their sustainability (Article 1). More indepth, it analyzed the implementation path of seven food forest for success factors, barriers and coping strategies (Article 2). Based on these insights, two experimental case studies were initiated to develop sustainable food forests with practice partners, one based in Phoenix, Arizona, U.S. and one in Lüneburg, Germany. Two studies analyzed the cases’outputs and processes highlighting success factors and challenges, including the role of a sustainable entrepreneurial ecosystem (Article 3, Phoenix case) and key features of productive partnerships to understand why one case succeeded and the other failed (Article 4). Findings include key features of existing and sustainable food forests as well as success factors on how to develop them; namely acquiring a complementary skill set that includes specialty farming and entrepreneurial know-how, securing sufficient start-up funds and long-term land access as well as overcoming regulatory restrictions. Supporting institutions are especially needed to integrate and professionalize the planning stage and provide know-how on alternative business practices. Key features of productive partnerships include an entrepreneurial attitude, access to support functions, long-term orientation and commitment to food system sustainability. The synthesis provides a detailed, ideal-typical implementation pathway to develop sustainable food forests and relevant supportive actors. This study provides researchers, food entrepreneurs, public officials, and activists with insights on how to develop and advance food forests as a sustainability solution.

Beyond Anthropocentric Perspectives on Education In light of the dramatic growth and rapid institutionalization of human-animal studies in recent years, it is somewhat surprising that only a small number of publications have proposed practical and theoretical approaches to teaching in this inter- and transdisciplinary field. Featuring eleven original pedagogical interventions from the social sciences and the humanities as well as an epilogue from ecofeminist critic Greta Gaard, the present volume addresses this gap and responds to the demand by both educators and students for pedagogies appropriate for dealing with environmental crises. The theoretical and practical contributions collected here describe new ways of teaching human-animal studies in different educational settings and institutional contexts, suggesting how learners – equipped with key concepts such as agency or relationality – can develop empathy and ethical regard for the more-than-human world and especially nonhuman animals. As the contributors to this volume show, these cognitive and affective goals can be achieved in many curricula in secondary and tertiary education. By providing learners with the tools to challenge human exceptionalism in its various guises and related patterns of domination and exploitation in and outside the classroom, these interventions also contribute to a much-needed transformation not only of today’s educational systems but of society as a whole. This volume is an invitation to beginners and experienced instructors alike, an invitation to (re)consider how we teach human-animal studies and how we could and should prepare learners for an uncertain future in, ideally, a more egalitarian and just multispecies world.

Extracting meaningful representations of data is a fundamental problem in machine learning. Those representations can be viewed from two different perspectives. First, there is the representation of data in terms of the number of data points. Representative subsets that compactly summarize the data without superfluous redundancies help to reduce the data size. Those subsets allow for scaling existing learning algorithms up without approximating their solution. Second, there is the representation of every individual data point in terms of its dimensions. Often, not all dimensions carry meaningful information for the learning task, or the information is implicitly embedded in a low-dimensional subspace. A change of representation can also simplify important learning tasks such as density estimation and data generation. This thesis deals with the aforementioned views on data representation and contributes to them. We first focus on computing representative subsets for a matrix factorization technique called archetypal analysis and the setting of optimal experimental design. For these problems, we motivate and investigate the usability of the data boundary as a representative subset. We also present novel methods to efficiently compute the data boundary, even in kernel-induced feature spaces. Based on the coreset principle, we derive another representative subset for archetypal analysis, which provides additional theoretical guarantees on the approximation error. Empirical results confirm that all compact representations of data derived in this thesis perform significantly better than uniform subsets of data. In the second part of the thesis, we are concerned with efficient data representations for density estimation. We analyze spatio-temporal problems, which arise, for example, in sports analytics, and demonstrate how to learn (contextual) probabilistic movement models of objects using trajectory data. Furthermore, we highlight issues of interpolating data in normalizing flows, a technique that changes the representation of data to follow a specific distribution. We show how to solve this issue and obtain more natural transitions on the example of image data.

The doctoral dissertation deals with the problems of the diagnosis of rolling bearings using recurrence analysis. The main topic is the influence of radial internal clearance on the change of dynamics in a self-aligning double-row ball bearing with a tapered bore, in which the axial preload can control this parameter in a wide range. The dissertation began with an analysis of the state of knowledge, where the works related to the analyzes of the impact of radial clearance on the dynamics of rolling bearings have been cited so far. In the next part of the dissertation, the thesis was formulated and activities related to its proving were defined. The theoretical part was supplemented with the basics related to vibroacoustic diagnostics of rolling bearings and presented methods that can be used for their diagnostics. The research on proving the thesis was started with the preparation of a mathematical model in which a change in the damping coefficient in the field of radial clearance was adopted, a difference in the clearance value for a given row of balls was proposed, and the influence of shape errors and radial shaft endplay on the dynamics of the tested bearing was taken into account. During the dynamics tests, the radial clearance was adopted as a bifurcation parameter, and on the basis of the bifurcation diagram, it was possible to indicate the characteristic areas of bearing operation due to the radial internal clearance. In order to verify the model, experimental tests were carried out with a series of bearings in which the radial clearance was changed in a wide range possible to be physically realized. Recurrence analysis was used for both the dynamic response obtained from model and experimental studies. Owing to the comparative analysis of the dynamic response, recurrence quantificators were selected that are most susceptible to changes in radial clearance to bearing dynamics. Moreover, as a result of the research, it was possible to select a narrow range of radial clearance, ensuring the smoothest operation of the tested bearing.

Die wissenschaftliche Arbeit analysiert den interkulturellen Austausch zwischen der Türkei und Deutschland auf der Ebene von Forschungskooperationen und bei Akquisitionsgesprächen in der Türkei. Anhand von weiteren Situationsanalysen werden auch die Erfahrungen der Autorin in Deutschland aufgezeigt. Die teilnehmenden Beobachtungen und Situationsanalysen vertiefen empirisch die Frage der kulturellen und sozialen Bedingungen einer Markterschließung im Bereich von menschlichen Beziehungen und ökonomischen Rahmenbedingungen – wobei vor allem Forschungskooperationen in den Feldern von Ernährung und Pharmazie von Interesse sind. Die Analysen der teilnehmenden Beobachtungen werden anhand der Kulturdimensionen von Hofstede durchgeführt, es wird gezeigt inwieweit diese anwendbar sind und mögliche Ergebnisse für die Bewertungen einer Kultur erlauben könnten. Die Kulturdimensionen von Hofstede stehen im Mittelpunkt dieser Arbeit. Zuerst wird die aktuelle politische und wirtschaftliche Lage der Türkei in den letzten 20 Jahren aufgezeigt, dann wird das Konzept der „Interkulturellen Kompetenz“ beleuchtet. Sodann wird das Kulturkonzept von Hofstede im interkulturellen Dialog betrachtet und die allgemeine Kritik an Hofstede dargestellt, auch alternative Theorieansätze werden beschrieben. Die Strategie des Fraunhofer Forschungsverbunds wird über das praktische Vorgehen beleuchtet und Faktoren für den Erfolg beschrieben. Die Arbeit schließt mit einem methodisch-philosophischen Ausblick hinsichtlich des Zusammenhangs vom korrelativen Denken und der Anwendung der Kulturdimensionen von Hofstede.

Algorithmic distribution has fundamentally altered the news industry and has led to conflicts over regulatory issues. Focusing on the introduction of European ancillary copyright, this chapter addresses an earlier international reform around algorithmic news distribution. Based on an in-depth thematic analysis of key documents from the policy formulation phase, the chapter maps the arguments for and against the ancillary copyright reform put forward by Google and news publishers in Germany. While we provide a detailed analysis of the underlying rationales of two key actors primarily affected by the regulation, we also place ancillary copyright in the context of competing private property and public policy visions, which allows for a better understanding of how and why different actors take particular positions on copyright reform and algorithmic regulation.

Transformative learning is increasingly set to become an essential component in sustainability transformation. This type of learning attracts considerable interest in studying and impulsing a paradigm change to transform our world into a more sustainable one, yet its underlying learning mechanisms have remained overlooked. Although there is an apparent relationship between transformative learning and sustainability transformation, little has been done to systematically explore the contribution to sustainability transformation. This learning theory developed decades ago independently of sustainability discourses; however, it provides an analytical framework for understanding the learning processes, outcomes and conditions in individual and social learning towards sustainability transformation. Against this background, the following research question arises: To which extent can transformative learning lead to sustainability transformation? This doctoral work aims to explore transformative learning processes, outcomes, and conditions occurring and advancing towards sustainability transformation of the textile-fashion industry in Mexico. Taking an exploratory approach, the methods employed were literature reviews to untangle concepts and to construct theoretical pillars to support the empirical research design and data analysis. For data collection, snowball-sampling techniques were used to explore the practice field of the textile-fashion industry in Mexico. Qualitative interviews were employed to gather data about the learning experiences of actors. Qualitative and quantitative methods were required to perform the respective data analysis, the qualitative codification of interviewees’ responses through MAXQDA being the most remarkable one. Analysis of social media content was also utilised to understand the communication and business practices of projects involved in the transformation of the textile-fashion sector. As a result, this work comprises three articles, one a systematic literature review and two empirical research articles, investigating the transformative learning processes of entrepreneurs in the development of sustainability niches. As for the findings of this doctoral work, the use of transformative learning in sustainability transformation requires a careful study of the theory and its conceptual elements. Regarding the case study, transformative learning is inherent in forming and developing sustainability niches as entrepreneurs venture into them: It is individual prior learning, expectations and actions that initiate the path of sustainability transformation while disorienting dilemmas, critical reflection, and discourse accelerate them. Through these stages, it is when individual learning turns into social learning. On the other hand, based on the multi-level perspective, the interplay between the niche, regime and landscape levels generates a space for sustainability transformation and transformative learning. This work contributes to deciphering the black box of learning in sustainability transformations. The principal endeavour was to build the theoretical bridges between this emerging area of inquiry and transformative learning theory, as a significant part of this theoretical construction required drawing upon other research fields such as sustainability transitions and sustainability entrepreneurship. The crosscutting feature of learning in those fields enabled the development of an awareness of boundary objects between those fields (e.g., expectations). Furthermore, this study is pioneering in exploring sustainability transformation processes of the textile-fashion industry in Latin American contexts. The findings of this work can also be extrapolated to other sectors in which entrepreneurs participate, such as local food production, sustainable mobility, among others

Destination websites, which are maintained by destination marketing/management organisations (DMOs), are a key source of information for tourists in the pre-trip phase. DMOs are increasingly applying experiential marketing on their websites to support positive pre-travel online destination experiences (ODEs) and make the vision of the holiday as vivid as possible. Thereby they aim to turn virtual visitors into physical visitors. However, research into technology-driven travel experiences is still in its infancy. In particular, a theoretical understanding of the nature of ODEs arising from destination websites is still lacking. Closing this knowledge gap is of great interest from a theoretical perspective; furthermore, it is of central importance for strategic marketing-controlling of destinations. Therefore, this dissertation is dedicated to an extensive investigation of ODEs on destination websites in the pre-travel phase. The aims were to analyse the influences of experiential design on ODEs, explore the ODE dimensions, and develop and validate a measurement tool for assessing the ODE values of destination websites. In the first qualitative multi-method study (eye-tracking, retrospective think-aloud protocols, semi-structured interviews, and video observations), the objective was to gain an in-depth understanding of the ODE facets in the travel inspiration phase. It was found that the experience dimensions adopted in previous research regarding the product-brand context (sensory, affective, intellectual, social, and behavioural dimensions) also occurred in the ODE context but exhibited some particularities, such as a future-oriented affective component (affective forecasting). Moreover, a supplementary spatio-temporal experience dimension was identified. An online field experiment was subsequently conducted and aimed at assessing the effects of applying experiential marketing on destination websites on ODEs in the travel inspiration phase. Based on the findings of Study 1, an initial attempt at developing an ODE measurement instrument was made and the ODE dimensionality tested. The results showed the theoretically relevant experience dimensions to be less differentiated compared to the product-brand context; instead, they merged into a holistic ODE encompassing several experience facets. Furthermore, it was shown that the application of experiential design enhanced ODEs; however, considering the subjectivity of experiences, the effect was rather small. Accordingly, complex multi-media elements do not automatically increase the experiential effect. In the third study, a quasi-online field experiment was conducted, simulating the travel information phase (higher involvement than Study 2) to re-assess the ODE dimensions and develop and validate a measurement instrument. The results showed the overall ODE to be reflected by two interrelated dimensions that aligned with the dual process theory: hedonic and utilitarian experiences. The facets identified in the first study were largely reflected in these two overarching components. Moreover, a reliable, valid, and parsimonious second-order measure for assessing ODEs was proposed. Overall, the results yielded by this dissertation enhance the scientific understanding of the technology-empowered tourist experience in the currently under-researched pre-travel experience phase. In addition, by proposing a new scale for the measurement of ODEs, this dissertation provides useful methodological advancements that can pave the way for further research in this field. The results will also be of great practical value for DMOs, as they yield a tool for controlling the experiential outcomes of websites as a base for strategic marketing decisions.

Städte müssen die Mobilitätsbedürfnisse vieler Individuen befriedigen. Der Verkehr – das Instrument, das Mobilität ermöglicht- hat jedoch einen Einfluss auf die Lebensqualität der städtischen Bevölkerung. Besonders der motorisierte Individualverkehr (MIV) steht u. a. wegen der Emission von Kohlenstoffdioxid (CO2), Schadstoffen, Lärm und eines hohen Flächenverbrauchs in der Kritik. Die Anzahl der Kraftfahrzeuge (Kfz) nimmt jedoch weiter zu. Viele Städte verfolgen daher das Ziel, den Kfz-Verkehr zu reduzieren und diesen teilweise auf den Umweltverbund (Fuß- und Radverkehr und öffentlicher Personennahverkehr) zu verlagern, um die Emissionen des Verkehrssektors zu minimieren, die Straßen zu entlasten und den städtischen Raum lebenswerter zu gestalten.

The worldwide decline of plant and insect species during the last decades has far-reaching consequences for the functionality of ecosystems and their inherent processes. Pollination as one of them is an indispensable ecosystem service for human wellbeing. More than 85% of the worldwide flowering-plant species depend to some degree on pollination by insects (pollinators). Similarly, many pollinators depend on the flowers of the plants, as they need nectar and pollen as food resources for themselves and their offspring. However, an increasing number of pollinator and plant species are threatened by multiple, interacting, and sometimes synergistic causes (habitat loss, fragmentation, diseases, parasites, pesticides, monocultures) that are becoming a growing threat to ecosystem functioning. Given the loss of plant species diversity, it is increasingly difficult for pollinators to find food throughout the year. Therefore, this study analyses the influence of plant diversity on pollinators. The study was conducted in the course of the Jena Experiment, which is a long-term biodiversity experiment (since 2002) with 60 plant species, common to Central European Arrhenatherum grasslands. With a plant diversity gradient of 1, 2, 4, 8, 16, and 60 plant species per plot, time-series data resulted from a wide range of ecosystem processes, ranging from productivity, decomposition, C-storage, and N-storage to herbivory, and pollination. These were studied to investigate the mechanisms underlying the relationships between biodiversity and ecosystem processes. Chapter 2 studies the spatio-temporal distribution of pollinators on flowers along an experimental plant diversity gradient. For this purpose, the pollinators were divided into four different functional groups, i.e. honeybees, bumblebees, solitary bees and hoverflies. In particular, the spatial pollinator behaviour was examined, that is, in which flowering height the flowers were visited within the plant community. In order to study the temporal component, pollinator visits were observed over the course of the day and the season. As a result, an unprecedented high resolution of plant-pollinator interactions was found. For the first time it was possible to demonstrate that the different pollinator functional groups can complementarily use different spatio-temporal niches which was most pronounced in species-rich plant mixtures,. This leads to the conclusion that species-rich plant mixtures provide sufficient resources that can be used by generalists, such as honeybees and bumblebees, as well as other pollinator functional groups, such as hoverflies and solitary bees. Chapters 3 and 4 continues on the chemical composition of flower nectar (nectar) of various plant species. Nectar is used as food resource for adult pollinators, but is also largely used as a supply for their offspring, making it the most important pollinator reward. The chemical composition of the nectar was analysed for the two most important macronutrients, carbohydrates (C) and amino acids (AA), using high performance liquid chromatography (HPLC). Subsequently, their contents were analysed in terms of concentration, proportional content and the ratio of carbohydrates to amino acids (C:AA). In Chapter 3, the nectar of 34 plant species from the grasslands of the Jena Experiment was compared. In doing so, similarities and/or differences of the nectar compositions were investigated with respect to the most important macronutrients carbohydrates and amino acids between the individual species but also between the most representative plant families. This should lead to a better understanding about how plant diversity influences consuming pollinators and which factors, e.g. phylogenetics, morphology or ecology, can lead to different nectar compositions. We could show that each plant species differs in terms of carbohydrate content, amino acid content and C:AA-ratio. In addition, there were clear differences between the four representative plant families Apiaceae, Asteraceae, Fabaceae and Lamiaceae regarding the proportions of essential amino acids. The proportions of the individual sugars and the C:AA-ratios also differed greatly between the four plant families. Therefore, it can be assumed that these nectar contents are family-specific. The need for differences in carbohydrate content are probably due to the different morphology of the flowers, as plants with open flowers and exposed nectar, as in Apiaceae and Asteraceae, can protect their nectar from evaporation if the nectar has a higher osmolality, which can be achieved by a higher hexose (fructose and glucose) content. Thus, the nectar can remain dilute for a longer time and consequently remain consumable for pollinators, which in turn can contribute to the pollination of plants. Fabaceae and Lamiaceae showed different results. Here the nectar was probably protected from evaporation by closed flowers, which explains the high proportion of sucrose, leading to a lower osmolality that would enhance evaporation for exposed nectar. The metabolic pathways controlling the family-specific C:AA-ratios are yet to be explored. In conclusion, it can be suggested that this study contributes to elucidating the morphological and phylogenetic characteristics that control each plant species’ nectar composition. In Chapter 4, nectar was investigated in the context of diversity effects on the example of the plant species Field Scabious, Knautia arvensis. It was analysed to what extent the nectar quality (nutrient content) differs between plant individuals of one species. The underlying factors causing these differences in nectar composition have never been studied before. In order to investigate these coherences, plant communities in the Jena Experiment of different plant species richness levels containing the target plant species K. arvensis were used. In particular, we examined whether the nectar of K. arvensis is influenced by other neighbouring plant species, e.g. through competition for pollinators. The carbohydrate and amino acid content in nectar varied both between individuals of K. arvensis and between the different plant species richness levels. However, there were significant non-linear differences in the proportions of certain essential and phagostimulatory amino acids, which were produced proportionally more in the nectar of K. arvensis plants in species-rich plant communities, while histidine, one of the generally inhibiting amino acids tended to be less present. Our findings therefore suggest that the nectar of K. arvensis is more palatable when the plants grow in species-rich plant communities. Overall, these studies indicate how fragile plant-pollinator interactions are but also how important plant species-rich grasslands are to support plant-pollinator interactions. Increased plant species diversity is essential to ensure the availability of flowering resources throughout the year. Pollinators, such as honeybees, bumblebees, solitary bees, and hoverflies can use the niches in time and in vertical space complementarily. However, in plant species-poor grasslands there may be more niche overlaps, which is probably due to a reduced availability of resources. This points to the need to include different plant species belonging to different plant families, whose nectar may have evolved in response to morphological flower traits and metabolic pathways. Therefore plant species diversity can supply pollinators with nectar differing in carbohydrate and amino acid content and thus differing in quality. Also C-AA ratios have proven to be a useful measurement to reveal differences between plant species. In addition, C:AA ratios were not differing in nectar of K. arvensis individuals growing in different plant species richness levels, although their nectar seemed to be more attractive in mixtures with 16 plant species, likely due to higher content of essential and phagostimulatory amino acids than in plant species-poor mixtures. Thus further research investigating diversified farming systems, including pollinator-friendly practices to reveal the attractiveness of different plant species. More diversified field margins and grasslands, for the maintenance of pollinator services for sustainable provision of crop pollination.

Urban areas are prone to climate change impacts. Simultaneously the world’s population increasingly resides in cities. In this light, there is a growing need to equip urban decision makers with evidence-based climate information tailored to their specific context, to adequately adapt to and prepare for future climate change. To construct climate information high-resolution regional climate models and their projections are pivotal, to provide a better understanding of the unique urban climate and its evolution under climate change. There is a need to move beyond commonly investigated variables, such as temperature and precipitation, to cover a wider breath of possible climate impacts. In this light, the research presented in this thesis is centered around enhancing the understanding about regional-to-local climate change in Berlin and its surroundings, with a focus on humidity. More specifically, following a regional climate modelling and data analysis approach, this research aims to understand the potential of regional climate models, and the possible added value of convection-permitting simulations, to support the development of high-quality climate information for urban regions, to support knowledge-based decision-making. The first part of the thesis investigates what can already be understood with available regional climate model simulations about future climate change in Berlin and its surroundings, particularly with respect to humidity and related variables. Ten EURO-CORDEX model combinations are analyzed, for the RCP8.5 emission scenario during the time period 1970 ̶ 2100, for the Berlin region. The results are the first to show an urban-rural humidity contrast under a changing climate, simulated by the EURO-CORDEX ensemble, of around 6 % relative humidity, and a robust enlarging urban drying effect, of approximately 2 ̶ 4 % relative humidity, in Berlin compared to its surroundings throughout the 21st century. The second part explores how crossing spatial scales from 12.5 km to 3 km model grid size affects unprecedented humidity extremes and related variables under future climate conditions for Berlin and its surroundings. Based on the unique HAPPI regional climate model dataset, two unprecedented humidity extremes are identified happening under 1.5 °C and 2 °C global mean warming, respectively SH>0.02 kg/kg and RH<30 %. Employing a double-nesting approach, specifically designed for this study, the two humidity extremes are downscaled to the 12.5 km grid resolution with the regional climate model REMO, and thereafter to the 3 km with the convection-permitting model version of REMO (REMO NH). The findings indicate that the convection-permitting scale mitigates the SH>0.02 kg/kg moist extreme and intensifies the RH<30 % dry extreme. The multi-variate process analysis shows that the more profound urban drying effect on the convection-permitting resolution is mainly due to better resolving the physical processes related to the land surface scheme and land-atmosphere interactions on the 3 km compared to the 12.5 km grid resolution. The results demonstrate the added value of the convection-permitting resolution to simulate future humidity extremes in the urban-rural context. The third part of the research investigates the added value of convection-permitting models to simulate humidity related meteorological conditions driving specific climate change impacts, for the Berlin region. Three novel humidity related impact cases are defined for this research: influenza spread and survival; ragweed pollen dispersion; and in-door mold growth. Simulations by the regional climate model REMO are analyzed for the near future (2041 ̶ 2050) under emission scenario RCP8.5, on the 12.5 km and 3 km grid resolution. The findings show that the change signal reverses on the convection-permitting resolution for the impact cases pollen, and mold (positive and negative). For influenza, the convection-permitting resolution intensifies the decrease of influenza days under climate change. Longer periods of consecutive influenza and mold days are projected under near-term climate change. The results show the potential of convection-permitting simulations to generate improved information about climate change impacts in urban regions to support decision makers. Generally, all results show an urban drying effect in Berlin compared to its surroundings for relative and specific humidity under climate change, respectively for the urban-rural contrast throughout the 21st century, for the downscaled future extreme conditions, and for the three humidity related impact cases. Added value for the convection-permitting resolution is found to simulate humidity extremes and the meteorological conditions driving the three impacts cases. The research makes novel contributions that advance science, through demonstrating the potential of regional climate models, and especially the added value of convection-permitting models, to understand urban rural humidity contrasts under climate change, supporting the development of knowledge-based climate information for urban regions.

Human activities have become a major driver of global change, so that global society and economy are facing consequences such as climate change, increasing scarcity of resources, environmental pollution and degradation as well as disturbances of ecosystem functioning and services.In order to meet these main challenges in an appropriate way, adequate starting points and solutions must be pursued at all levels to shift the current socio-economic pathway from an unsustainable to a safe operating and thus sustainable development within the planetary boundaries. One of the application concepts in industrial contexts is Industrial Symbiosis (IS), which deals with the set-up of advanced circular/cascading systems, in which the energy and material flows are prolonged for multiple material and energetic (re-)utilization within industrial systems in order to increase resource productivity and efficiency, while reducing environmental impacts. The overarching goal of the research project was to identify and develop approaches to enable the evolution of Industrial Symbiosis (IS) in Industrial Parks (IPs). Industrial Symbiosis (IS) is a collaborative cross-sectoral approach to connect the resource supply and demand of various industries in order to optimize the resource use through exchange of materials, energy, water and human resources across different companies, while generating ecological, technical, social and economic benefits. Many Information Communication Technology (ICT) tools have been developed to facilitate IS, but they predominantly focus on the as-is analysis of the IS system, and do not consider the development of a common desired target vision or corresponding possible future scenarios as well as conceivable transformation paths from the actual to the defined (sustainability) target state. This gap shall be addressed in this work, presenting the software requirements engineering results for a holistic IT-supported IS tool covering system analysis, transformation simulation and goal-setting. This study also aims to present the conceptual IT-supported IS tool and its corresponding prototype, developed for the identification of IS opportunities in IPs. This IS tool serves as an IS facilitating platform, providing transparency among market players and proposing potential cooperation partners according to selectable criteria (e.g. geographical radius, material properties, material quality, purchase quantity, delivery period). Therefore a quantitative indicator system was compiled and recurring patterns were identified to utilize this knowledge in the comprehensive IT-supported IS tool. So this IS tool builds the technology-enabled environment for the processes of first screening of IS possibilities and initiation for further complex business-driven negotiations and agreements for long-term IS business relationships.

The significance of selecting suitable talent A company’s success is significantly influenced by the professionalism and quality of decision-making, especially selecting decisions to hire suitable talent. The term “talent” can be taken to mean as someone who has talent (talent as the sum of one’s abilities) and someone who is a talent. Leadership talent makes a difference in organizational success, has the potential to succeed as a leader, and thus will hold corresponding pivotal positions. In this book, we focus on the selection and acquisition of leadership talent, since such talent is more difficult to find in the market and, at the same time, more challenging to select. Selecting these talented individuals is one of the most critical components of effective organizations. Hardly any other corporate decision has such significant effects on corporate success as talent selection. Recruiting and personnel selection are also the first steps in promoting capability building and creating successful teams. For example, Warren Buffet, renowned for his investing prowess, says, “I have only two jobs. One is to attract and keep outstanding managers to run our various operations”. This highlights the need for an effective and efficient personnel selection process and to improve the diagnostic performance of such procedures. In addition, the increasing diversity of applicants, global competitiveness, and the lack of qualified personnel in specific labor and job markets also increase the importance of high-quality personnel selection processes.

Many dynamics are reshaping the global macroeconomics and finance. This cumulative dissertation empirically examines the impacts of two major global dynamics, the disaster risks and the China’s rise, on the global economy. Chapter 1 introduces the motivation and summarizes the dissertation. Chapter 2 investigates how geopolitical risks affect financial stress in the whole financial system and its sub-sectors (banking, stock, foreign exchange, bond) of major emerging economies. Chapter 3 shows how different disaster risks (financial, geopolitical, natural-technological) can explain the returns and risk premiums of stock and housing in advanced economies between 1870 and 2015. Chapter 4 examines how the rise of China is contributing to higher economic growth in emerging economies, especially after the Global financial crisis of 2007-2008. Chapter 5 illustrates how a close trade and investment relation with China has helped African countries to reduce poverty and to improve their income distribution.

Der vorliegende Beitrag liefert eine deskriptive Analyse von wichtigen Einflussgrößen auf die Zu-friedenheit. Betrachtet werden drei bedeutsame Arbeitsbedingungen und vier auf die Lebensbe-wältigung bezogene Einstellungen. Als Ausgangshypothese dient die Vermutung, dass die Korrela-tionen zwischen den Arbeitsbedingungen und der Arbeitszufriedenheit enger sind als die Korrela-tionen zwischen den Arbeitsbedingungen und der Lebenszufriedenheit. Umgekehrt ist zu vermu-ten, dass die Einstellungen einer Person sich enger mit ihrer Lebenszufriedenheit als mit der Ar-beitszufriedenheit verbinden. Als Datenbasis dient das Sozioökonomische Panel.

Bildung für nachhaltige Entwicklung (BNE) wird oft als ein entscheidendes Instrument dafür betrachtet, Menschen weltweit dazu zu befähigen, sich für globale Gerechtigkeit und für den Erhalt der Lebensgrundlagen heutiger und künftiger Generationen einzusetzen, beispielsweise in den ‚Sustainable Development Goals‘ (SDGs) als Ziel. Obwohl sich Nachhaltigkeitsprobleme bereits seit einigen Jahrzehnten deutlich abzeichnen und ein großer Handlungsbedarf empirisch eindeutig festgestellt wurde, sehen sich Wissenschaftler*innen in vielen Teilbereichen gegenwärtig mit einer hartnäckig anhaltenden nicht-nachhaltigen Entwicklung in der Welt konfrontiert. Dies erklärt sich unter anderem durch das Phänomen, dass Erkenntnisprozesse, Handlungsbereitschaft und Sinngebung bei Menschen keine rein kognitiven Prozesse rationaler Abwägungen sind. Aus dem Bestreben lösungs- und handlungsorientiert zu forschen resultiert eine Öffnung für multisensorische und körperliche Praktiken in den Nachhaltigkeitswissenschaften, und es gibt daher auch Interesse für kunst-basierte Ansätze. Ästhetische Ansätze werden als Notwendigkeit für die Transformation hin zu einer nachhaltigen Welt beschrieben. Sie sollen die Etablierung von cultures of sustainability ermöglichen.

Does the presentation of travel experience affect personal prestige of tourists? Prestige enhancement has been considered a motive for travel by tourism researchers for decades. Yet, the question whether representation of travel experience actually leads to personal prestige enhancement has been widely neglected so far. The study of prestige benefits of travel is a necessary endeavour to develop suitable methodological approaches toward the concept, in order to close critical knowledge gaps and enhance scientific understanding. The present thesis lays out the rationale and results of three research projects which shed light onto the relationship between touristic self-presentation and its effects on personal prestige evaluations of the social environment. The empirical studies conducted in the frame of this dissertation conclude in the following main findings: Leisure travel is a useful means for people to self-express in a positive way, and material representations of travel are frequently displayed to others. Tourists make use of travel experience to self-present in a positive way by uploading photos on social media, collecting and displaying souvenirs, wearing jewellery and clothing from their last trip, or talking about their trips to others. They express positive self-messages about personal character traits, affiliation to social in-groups and proof of having travelled somewhere. The findings ascertain the utility of travel representations for positive self-expression, showing that travel experience is an effective vehicle for conspicuous consumption and self-expression as an antecedent for personal prestige enhancement. Personal prestige is an element of social relations, and holds capacity to affect perceptions of social inclusion and social distinction, so it has to be conceptualised as a multidimensional construct. In a tourism context, personal prestige is reliably measurable along the four dimensions of hedonism, social inclusion, social distinction and prosperity. The herein developed Personal Prestige Inventory (PPI) is a valid, reliable and parsimonious measurement tool which substantially enhances methodological approaches toward empirical research into personal prestige. The way in which people represent travel experience to others measurably affects how their personal prestige is evaluated by social others. Empirical evidence of a series of experimental studies provides support for the assumption that representation of travel experience has an effect on the social evaluation of tourists’ personal prestige. Experimental variance suggests small to moderate effects on personal prestige depending on the amount of leisure information given about a person, participation in tourism, and the destination and type of travel represented. This evidence is reasonable basis to conclude that whether and how people travel, and whether and how they share travel experience with others, does measurably affect social other’s evaluation of their personal prestige. By providing qualitative evidence for positive self-presentation through leisure travel, and the subsequent development and experimental application of the Personal Prestige Inventory (PPI) in a tourism context, the present dissertation enhances scientific understanding of personal prestige in the context of leisure travel and provides useful methodological advancements for further research into the topic.

Im naturwissenschaftlichen Unterricht werden Hypothesen geprüft, Modelle genutzt, Experimente durchgeführt, Phänomene mit naturwissenschaftlichen Konzepten erklärt, die naturwissenschaftliche Fachsprache verwendet, gesellschaftliche Anliegen über Nachhaltigkeitskriterien erörtert usw. (KMK, 2004a, 2004b, 2004c). Von diesen Charakteristika des naturwissenschaftlichen Unterrichts können Barrieren ausgehen, die dazu führen, dass nicht alle Schüler*innen an dem naturwissenschaftlichen Lernen partizipieren können (Ferreira González et al., 2021). Schüler*innen können Fehlvorstellungen von naturwissenschaftlichen Konzepten entwickeln oder motorische Schwierigkeiten beim Experimentieren zeigen (Schlüter, 2018). Lehrkräfte stehen vor der Aufgabe, den naturwissenschaftlichen Unterricht inklusiv zu gestalten, wobei diese Barrieren reduziert und den Schüler*innen Zugänge geboten werden sollen. Von den Charakteristika naturwissenschaftlichen Unterrichts können nicht nur Barrieren, sondern auch Potentiale zur inklusiven Gestaltung ausgehen (Ferreira González et al., 2021; Abels & Brauns, 2020). Unter anderem können Phänomene anschaulich, verblüffend sowie auf unterschiedlichen Abstraktionsebenen präsentiert werden (Menthe & Hoffmann, 2015). Insgesamt fühlen sich Lehrkräfte jedoch noch nicht ausreichend vorbereitet, ihren Unterricht inklusiv zu gestalten (van Miegham et al., 2020). Aus diesem Grund fordern Simon und Moser (2019) hochschuldidaktische Lehrformate für die Professionalisierung für den inklusiven Fachunterricht zu entwickeln. Im BMBF geförderten Projekt Nawi-In (Naturwissenschaftlichen Unterricht inklusiv gestalten) sind wir dieser Forderung nachgegangen, indem die Entwicklung professioneller Kompetenzen für den inklusiven naturwissenschaftlichen Unterricht von Lehramtsstudierenden der Primar- und Sekundarstufe beforscht wurde. Dabei wurden Lehramtsstudierende des naturwissenschaftlichen Primar- und Sekundarstufenunterrichts über drei Semester im Projektbandseminar begleitet. Im ersten Semester haben die Studierenden ihr theoretisches Wissen zum inklusiven naturwissenschaftlichen Unterricht vertieft, im zweiten Semester haben sie im Zuge der Praxisphase (halbjähriges Praktikum in der Schule) eigenen inklusiven naturwissenschaftlichen Unterricht gestaltet, reflektiert und beforscht, im dritten Semester fand die Aufbereitung und Analyse der Daten statt (Brauns et al., 2020). Als Teilprojekt des Nawi-In Projekts setzt diese Arbeit den Schwerpunkt auf drei Fokusse: die Entwicklung des Kategoriensystems inklusiver naturwissenschaftlicher Unterricht (KinU), die Beforschung der professionellen Handlungskompetenz sowie der professionellen Wahrnehmung bzgl. inklusiven naturwissenschaftlichen Unterrichts. Im ersten Fokus geht es sowohl um die Entwicklung und Validierung des KinUs als auch um die Überprüfung der Gütekriterien des KinUs (Brauns & Abels, 2020, 2021b). Zunächst wurden die Charakteristika inklusiven naturwissenschaftlichen Unterrichts, die die Kategorien des KinUs 1.0 darstellen, in einem systematischen Review aus der Literatur (n=297) induktiv abgeleitet. Bei diesem Verfahren wurden insgesamt n=935 Kategorien abgeleitet, die sich auf insgesamt vier Abstraktionsebenen von der allgemeinen Hauptkategorien-, über die Subkategorien-, Code- bis hin zur konkreten Subcode-Ebene des KinUs verteilen. Während zunächst n=16 Kategorien die Verbindung naturwissenschaftlicher Charakteristika mit der inklusiven Umsetzung auf der Hauptkategorien-Ebene gebildet haben, waren es nach der Weiterentwicklung und Überarbeitung des KinUs 2.0 n=15 Hauptkategorien. Die Weiterentwicklung des KinUs fand mithilfe der Validierung durch Datentriangulation statt. Durch die Anwendung des KinUs auf Video- und transkribierte Audiodaten wurden fortlaufend weitere Kategorien induktiv abgeleitet. Das KinU 2.0 besitzt insgesamt über alle vier Ebenen n=2117 Kategorien. Zudem wurde die Struktur des KinUs vereinfacht, sodass die inklusiven Zugänge zu jedem naturwissenschaftlichen Charakteristikum bis zur Code-Ebene als ein gleichbleibendes Muster abgebildet werden können. Mit der Überarbeitung des KinUs wurden die Gütekriterien der qualitativen Forschung empirische Fundierung, Reproduzierbarkeit, Reliabilität, Kohärenz und Limitationen sowie Übertragbarkeit überprüft und begründet bestätigt. Der zweite Fokus bezieht sich auf die Entwicklung und Beforschung der professionellen Handlungskompetenz der Lehramtsstudierenden bzgl. inklusiven naturwissenschaftlichen Unterrichts (Brauns & Abels, eingereicht, in Vorb. a, in Vorb. b). Dabei wurde analysiert, welche inklusiv naturwissenschaftlichen Charakteristika Lehramtsstudierende in ihrem Unterricht implementieren, wie sich ihre professionelle Handlungskompetenz während der Praxisphase entwickelt sowie welche Unterschiede und Gemeinsamkeiten sich für die Primar- und Sekundarstufen bzgl. ihrer professionellen Handlungskompetenz ergeben. Dafür wurden die Unterrichtsvideos, die die Studierenden während der Praxisphase jeweils zweimal von ihrem eigenen Unterricht angefertigt haben, mit dem KinU qualitativ inhaltlich analysiert. Insgesamt haben die Studierenden zwar unterschiedliche Zugänge auf der Subkategorien-Ebene zum naturwissenschaftlichen Unterricht implementiert, allerdings haben sie den Schüler*innen innerhalb dieser Zugänge nur selten verschiedene Optionen geboten. Das bedeutet, dass Studierende beispielsweise zur Anwendung naturwissenschaftlicher Untersuchungsmethoden zwar einen bestimmten Grad an Offenheit und ausgewählte kommunikative Zugänge gestaltet haben, innerhalb der Offenheitsgrade aber nur das geleitete Experimentieren für alle Schüler*innen angeboten haben. Im Vergleich der Schulstufen zeigt sich, dass sich die zunehmende Fachlichkeit von der Primar- zur Sekundarstufe wiederspiegelt. Insgesamt haben die Studierenden von dem ersten zum zweiten Unterrichtsvideo zunehmend mehr inklusiv naturwissenschaftliche Charakteristika in ihren Unterricht implementiert. Im dritten Fokus wurde die professionelle Wahrnehmung von Lehramtsstudierenden bzgl. inklusiven naturwissenschaftlichen Unterrichts beforscht (Brauns & Abels, in Vorb. a, in Vorb. b). Dabei wurde analysiert, welche inklusiv naturwissenschaftlichen Charakteristika Lehramtsstudierende wahrnehmen, wie sich ihre professionelle Wahrnehmung entwickelt sowie welche Unterschiede und Gemeinsamkeiten sich für die Primar- und Sekundarstufe bzgl. ihrer professionellen Wahrnehmung ergeben. Dafür wurden video-stimulierte Reflexionen durchgeführt, wobei die Studierenden Videoszenen bzgl. inklusiven naturwissenschaftlichen Unterrichts beschreiben, interpretieren sowie Handlungsalternativen generieren sollten. Bei den Video-Stimulated Reflections (VSRef) haben die Studierenden eine Videovignette aus einem Sachunterricht zum Thema Löslichkeit reflektiert. Die VSRefs wurden zu drei Zeitpunkten durchgeführt: vor dem ersten Mastersemester und vor sowie nach der Praxisphase im zweiten Mastersemester. Zudem wurden während der Praxisphase jeweils zweimal mit allen Studierenden Video-Stimulated Recalls (VSR) durchgeführt. Dabei haben die Studierenden Ausschnitte ihrer eigenen Unterrichtsvideos reflektiert. Sowohl die VSRef als auch die VSR wurden transkribiert und mit dem KinU qualitativ inhaltlich analysiert. Die Lehramtsstudierenden haben zunehmend mehr inklusiv naturwissenschaftliche Charakteristika in den eigenen und fremden Unterrichtsvideos wahrgenommen. Zwischen den Schulstufen waren nur geringe Unterschiede zu erkennen. Am häufigsten haben die Studierenden Zugänge zur inklusiven Gestaltung der Anwendung naturwissenschaftlicher Untersuchungsmethoden wahrgenommen. Insgesamt zeigt sich, dass die Lehramtsstudierenden ihre professionellen Kompetenzen bzgl. inklusiven naturwissenschaftlichen Unterrichts weiterentwickeln konnten. Zudem wurde mit der Entwicklung des KinUs ein Kategoriensystem zur Beforschung und ein Unterstützungsraster für Lehrkräfte zur Gestaltung inklusiven naturwissenschaftlichen Unterrichts geschaffen. Als Mehrwert für weitere Erkenntnisse im Bereich des inklusiven naturwissenschaftlichen Unterrichts ist es interessant, weitere Daten in die Analyse der professionellen Kompetenzen (angehender) Lehrkräfte einzubeziehen. Beispielsweise können Schüler*innen beobachtet werden, inwiefern sie partizipieren, um mit Bezug auf die Implementierung inklusiv naturwissenschaftlicher Charakteristika Rückschlüsse zu ziehen, inwieweit der naturwissenschaftliche Unterricht tatsächlich inklusiv gestaltet wurde

Biodiversity is quickly diminishing across the planet, primarily owing to human pressures. Protected areas are an essential tool for conserving biodiversity in response to increasing human pressures. However, their ecological effectiveness is contested and their capacity to resist human pressures differ. This dissertation aimed to assess the ecological effectiveness of different protection levels (from strict to less strictly protected: national park, game reserve, forest reserve, game-controlled area, and unprotected areas) in biodiversity (both mega diverse butterflies and mammals), maintaining habitat connectivity, and reducing anthropogenic threats at the wider landscape in the Katavi-Rukwa Ecosystem of southwestern Tanzania. To achieve this overarching goal, I employed an interdisciplinary approach. First, I analyzed butterfly diversity and community composition patterns across protection levels in the Katavi-Rukwa Ecosystem. I found that species richness and abundance were highest in the game reserves and game-controlled areas, intermediate in the forest reserves, national park and unprotected areas. Species composition differed significantly among protection levels. Landscape heterogeneity, forest cover, and primary productivity influenced species composition. Land-use, burned areas, forest cover, and primary productivity explained the richness of species and functional traits. Game reserves hosted most indicator species. Second, I modelled the spatial distribution of six large mammal target species (buffalo Syncerus caffer, elephant Loxodonta africana, giraffe Giraffa camelopardalis, hartebeest Alcelaphus buselaphus, topi Damaliscus korrigum, and zebra Equus burchellii) across environmental and protection gradients in the Katavi-Rukwa Ecosystem. Based on species-specific density surface models, I found relatively consistent effects of protection level and land-use variables on the spatial distribution of the target mammal species: relative densities were highest in the national park and game reserves, intermediate in forest reserves and game-controlled areas and lowest in un-protected areas. Beyond species-specific environmental predictors for relative densities, our results highlight consistent negative associations between relative densities of the target species and distance to cropland and avoidance of areas in proximity to houses. Third, I examined temporal changes in land-use, population densities and distribution of six large mammal target species across protection levels between 1991 and 2018. During the surveyed period, cropland increased from 3.4 % to 9.6 % on unprotected land and from ≤0.05 % to <1 % on protected land. Wildlife densities of most, but not all target species declined across the entire landscape, yet the onset of the observed wildlife declines occurred several years before the onset of cropland expansion. Across protection levels, wildlife densities occurred at much greater densities in the national park and game reserves and lowest in the forest reserves, game-controlled areas and unprotected areas. Based on logistic regression models, target species preferred the national park over less strictly protection levels and areas distant to cropland. Because these analyses do not support a direct relationship between the timing of land-use change and wildlife population dynamics, other factors may account for the apparent ecosystem-wide decline in wildlife. Fourth, I quantified land-use changes, modelled habitat suitability and connectivity of elephant over time across a large protected area network in southwestern Tanzania. Based on analyses of remotely-sensed data, cropland increased from 7% in 2000 to 13% in 2019, with an average expansion of 634 km2 per year. Based on ensemble models, distance from cropland influenced survey-specific habitat suitability for elephant the most. Despite cropland expansion, the locations of the modelled elephant corridors (n=10) remained similar throughout the survey period. According to ecological knowledge, nine of the modelled corridors were active, whereas one modelled corridor had been inactive since the 1970s. Based on circuit theory, I prioritize three corridors for protected area connectivity. Key indicators of corridor quality varied over time, whereas elephant movement through some corridors appears to have increased over time. Overall, this dissertation underpins differences in ecological effectiveness of protected areas within one ecosystem. It highlights the need to utilize a landscape conservation approach to guide effective conservation across the entire protection gradient. It also suggests the need to enforcing land use plans and having alternative and sustainable forms for generating income from the land without impairing wildlife habitat.

Die Neuen Frauenbewegungen, durch die sich ab Ende der 1960er Jahre Akteur*innen zusammenschlossen, um sich für die individuelle Selbstbestimmung, Freiheit, Gleichheit und somit gegen herrschende geschlechtliche Leitbilder stark zu machen, trugen maßgeblich dazu bei, dass häusliche Gewalt nicht mehr nur als persönliches Schicksal einer Frau verstanden wird. Sie steht nun für den Ausdruck von Dominanz eines Geschlechts (dem anderen gegenüber). Durch mediale Kampagnen und die öffentliche Diskussion wurde Gewalt in nahen sozialen Beziehungen sichtbar gemacht, sodass sie nicht mehr als Familienstreitigkeit oder Privatangelegenheit gewertet wird. Heutzutage gilt häusliche Gewalt nicht mehr als persönliches Beziehungsproblem, sondern als Menschenrechtsverletzung und wird dementsprechend anerkannt sowie geahndet. Durch eine geänderte Gesetzgebung und Bundes- sowie Landesaktionspläne zur Bekämpfung von häuslicher Gewalt kam es zu einer Verbesserung der Situation, aber ist das ausreichend? Das Gewaltthema ist sowohl von emotionaler und moralischer als auch von politischer Brisanz. Mindestens jede vierte Frau, die in Deutschland lebt, war schon einmal von sexueller oder körperlicher Gewalt durch eine*n Beziehungspartner*in betroffen. Im Gegensatz dazu gilt die Betroffenheit von Männern bezüglich häuslicher Gewalt als umstritten, da es insbesondere zu sexualisierter Gewalt gegen Männer kaum Erkenntnisse gibt.

Freiwillig Engagierte als Koproduzent:innen der Teilhabe geflüchteter Familien in frühpädagogischen Angeboten in Niedersachsen. Deutungen von freiwillig Engagierten, Koordinator:innen und geflüchteten Eltern. Während die gleichberechtigte Teilhabe geflüchteter Familien an frühpädagogischen Angeboten erklärtes integrationspolitisches Ziel ist, gibt es Hinweise darauf, dass diese besonderen Herausforderungen unterliegt und dass freiwillig Engagierte dabei häufig involviert sind. Dabei ist wenig über die Dynamiken bekannt, wie freiwillig Engagierte geflüchtete Familien im Bereich der frühkindlichen Bildung, Betreuung und Erziehung begleiten, insbesondere aus Perspektive von geflüchteten Eltern und ihren Begleiter:innen. Vor diesem Hintergrund hat die vorliegende kumulative Dissertation das Ziel, durch die sinnverstehende Herausarbeitung von Deutungen der Begleiter:innen und geflüchteten Eltern zu einem besseren Verständnis der durch freiwilliges Engagement begleiteten Teilhabe geflüchteter Familien an frühpädagogischen Angeboten beizutragen. Die Dissertation begreift freiwillig Engagierte als ‚Koproduzent:innen‘ von integrationspolitischen Zielen. Auf Grundlage von 34 Interviews mit Engagierten, Koordinator:innen und geflüchteten Eltern, welche in neun Kommunen in Niedersachsen geführt wurden, wurden in drei Artikeln die folgenden Schwerpunkte bearbeitet: Deutungen der Zusammenarbeit zwischen zivilgesellschaftlichen und staatlichen Akteur:innen durch die Begleiter:innen durch Anbindung an das Konzept Koproduktion (Artikel 1), Deutungen von Problemen und Lösungen durch die Begleiter:innen anknüpfend an die Konzepte Vulnerabilität und Agency (Artikel 2) sowie Deutungen der Eltern als Zielgruppe, mit Blick auf deren Aufbau von Vertrauen gegenüber frühpädagogischen Angeboten (Artikel 3). Die Dissertation trägt zu den folgenden wissenschaftlichen Debatten bei: zu Dynamiken der Umsetzung von Policies, wenn zivilgesellschaftliches Engagement dabei eine zentrale Funktion einnimmt, sowie zur Umsetzung integrationspolitischer Ziele im konkreten Bereich der Nutzung frühpädagogischer Angebote durch geflüchtete Familien. Es zeigt sich, dass freiwillig Engagierte zwar staatliche Akteur:innen ergänzen und damit maßgeblich zur Umsetzung integrationspolitischer Ziele beitragen. Gleichzeitig deutet dies aber auf strukturelle Hürden hin und wirft die Frage auf, inwieweit das freiwillige Engagement hier die Verantwortung für staatliche Aufgaben übernimmt. Dabei treten in der Zusammenarbeit zwischen zivilgesellschaftlichen und staatlichen Akteur:innen häufig Konflikte auf, welche auf divergierende Deutungen des Begriffs ‚Integration‘ und eine fehlende Ausdefinition konkreter sich aus den integrationspolitischen Zielen ableitender Bedarfe beruhen.

This research report presents a transdisciplinary student research project on developing climate resilience of communities in Marine Protected Areas in the Lesser Antilles. For the second time, the Leuphana University Lüneburg and the Sustainable Marine Financing Programme (SMF) of the Deutsche Gesellschaft für internationale Zusammenarbeit (GIZ) partnered up. The first project on the Caribbean Island Dominica showed that community resilience is a complex concept that is not yet well understood. Building on these findings, this year’s project broadened the scope in addressing the effect of varying local conditions on climate resilience on four different Caribbean islands: Dominica, Grenada, St Lucia, and St. Vincent and the Grenadines. For the GIZ, the research project aimed at improving the understanding of the socio-ecological resilience framework for tackling problems of Marine Managed Areas (MMA) and Marine Protected Areas (MPA). Also, it enabled new thoughts on how the GIZ and other development agencies can more effectively assist island states to better cope with the challenges of climate change. The role of the students from the “Global Environmental and Sustainability Sciences” programme of Leuphana University included the design of four transdisciplinary research projects to study the effect of varying local conditions in disaster-prone regions in the Southern Caribbean on climate resilience. The developing island states in the Caribbean are extremely vulnerable to more frequent and intense natural hazards while relying on ecosystem services that are threatened by extreme weather events, in particular Hurricanes. After such adverse events, low economic stability leads to a dependency of the states on international assistance. To decrease the vulnerability to shocks, counteracting measures that encourage learning and adaptation can increase the resilience against extreme weather events and their consequences. Concepts that were considered during the design of the transdisciplinary research projects were the adaptation of systems, diversity and stakeholder participation and resilience-focused management systems. Building on the results from last year in Dominica, the establishment of a four islands design allowed for greater comparison to better understand community approaches to solve a concrete sustainability problem: securing livelihoods while protecting natural and cultural resources. The research methods of a literature review, stakeholder mapping, semi-structured interviews, scenario development and visioning were used in the projects. A comparison of the four TD projects revealed four overarching lessons. First, all countries recognise a need for restoration and conservation projects, i.e., nature-based solutions implemented and managed by the local community in the MPA. Furthermore, all four cases show that the limited participation of local people in the management and organisation of the MPA is a factor constraining community resilience. Third, this TD project highlights the importance to distinguish climate change as an event or as a process. When climate change occurs as a series of disaster events (e.g., hurricanes, floodings, and heatwaves) in combination with s gradual degradation of natural ecosystems (e.g., coral bleaching and ocean warming), people in MPA communities show highly adaptive and restorative behaviour. Finally, this project was an attempt to realize a cross-cultural and virtual transdisciplinary project. The research approach of transdisciplinarity links different academic disciplines and concepts, and non-scientific stakeholders are included to find solutions for societal and related scientific problems. A major learning was that in virtual TD projects particular attention needs to be paid to setting clear boundaries and be explicit about success criteria. Nonetheless, the findings of the projects provide valuable learning lessons to be applied in practice and that can prove useful for future research.

Die vorliegenden kumulativen Habilitationsschriften fokussieren auf die sozialen Prozesse, die bei der Standardisierung und der Dekonstruktion von soziokulturellen Differenzen zu Tage treten. Der Schwerpunkt liegt dabei auf den Arten und Weisen, in denen verschiedene Konzepte der Diversität und Alterität in der kuratorischen Praxis globaler Musik- und Performing Arts-Festivals (de-)konstruiert werden. Aus transkultureller Perspektive werden jeweils exemplarisch die vielfältigen Politik(en) der Macht im Feld der globalen Künste diskutiert, die mit komplexen sozialen Prozessen der Normierung und Konventionalisierung als auch mit Gegenmaßnahmen und Dekolonialisierungsbestrebungen einhergehen sowie strukturierenden Rahmenbedingungen unterliegen. Dadurch wird das komplexe Zusammenspiel von Diskursen (beziehungsweise Symbolen und Narrativen) und Performanz (beziehungsweise von Praktiken und sozialen Beziehungen) als auch von Repräsentation (beziehungsweise von Politiken und Strukturen) von Diversität und Alterität im Forschungsfeld untersucht. Damit profilieren die Schriften eine postkolonial orientierte Kulturforschung, die sich sowohl auf Kontingenzen des menschlichen Zusammenlebens als auch auf ihre symbolischen Routinisierungen, soziale Ungleichheiten, ambivalente sowie konflikthafte Aushandlungsprozesse und zugrundeliegende Machtverhältnisse beziehen.

Diese Bachelorarbeit hat das Ziel, die Wirkung der innerhalb der PPS-Hauptaufgabe Produktionsprogrammplanung verwendeten Verfahren auf die logistischen Zielgrößen der unternehmensinternen Lieferkette zu modellieren. Dafür werden zunächst die Grundlagen der Produktionsplanung und -steuerung (PPS) sowie das Hannoveraner Lieferkettenmodell (HaLiMo) dargelegt. Es werden die zur Erfüllung der PPS-Aufgaben Absatzplanung und langfristige auftragsanonyme Ressourcengrobplanung verwendeten Verfahren aufgegriffen und detailliert beschrieben. Anschließend werden die Wirkbeziehungen zwischen diesen Verfahren und den logistischen Zielgrößen modelliert, wobei verschiedene Fallbeispiele betrachtet werden, welche als Ausgangspunkt dienen und jeweils unterschiedliche Auswirkungen auf die Zielgrößen aufzeigen. Aus den Modellen geht hervor, dass die Auswahl geeigneter bzw. adäquater Verfahren sowie die richtige Durchführung dieser unmittelbar auf die Zielgrößen der unternehmensinternen Lieferkette einwirken. Die Ergebnisse dieser Bachelorarbeit akzentuieren somit die Auswirkungen sowie die Relevanz der im Rahmen der Produktionsprogrammplanung verwendeten Verfahren und erleichtern die Handhabung der PPS-Konfiguration in einem praxisnahen Umfeld.

New media and digital technologies open up numerous possibilities to document different versions of reality, which makes it essential to examine how they transform the logic behind the creation and production of documentaries in digital cultures. The goal of this study is to inves-tigate the integration between the traditional documentary and new media: the interactive doc-umentary, in the context of the different sociocultural and technological environments of China and the West. Accordingly, a comparative study on the evolution and integration of these two fields was carried out. The documentary genre brings with it a method of classification and various modes of representing reality, while new media provide new approaches to interactivity as well as the production and distribution of interactive documentaries. In this context, the study examines the differences and characteristics of interactive documentaries in China and the West. Interactive documentaries grow and change as a continuously evolving system, engaging the roles of the author and the user, such that their roles are mixed for better co-expression and the reshaping of their shared environment. In addition, an analytical approach based on the types of interactivity was adopted to explore this new form of documentary both to deduce how the stories about our shared world can be told and to understand the impact of interactive doc-umentaries on the construction of our versions of the reality as well as our role in it.

Contemporary society is shaped by the idea that time is, above all, a scarce economic resource that must be used efficiently – “time is money” not to be wasted. Increasingly, however, scientific findings suggest that such a way of perceiving of time seems a major cause of the current global climate and sustainability crisis. So far, this research has often focused on mobility, energy consumption, or the structural conditions of the social organisation of time. Considerably less work has been carried out in relation to the role of individual time-related needs regarding unsustainable consumption behaviour, although consumer research has been addressing needs-oriented approaches to sustainable consumption for a long time. Environmental and Sustainability Education (ESE) is considered an essential strategy to achieve the global sustainability goals of Agenda 2030. Internationally, as well as on a national level, ESE is increasingly mainstreamed in educational curricula and practice, including in Germany. Given the relation between time, needs and sustainability, it appears valuable to inquire into this field from the perspective of ESE – where time as a resource for sustainability has received comparatively little attention so far. The core research interest of this cumulative dissertation is therefore the question of how the connection between time, our needs and sustainability can be conveyed through pedagogical approaches. The inquiry used an exploratory, qualitative research design to address this question. In a first step, the concept of sustainability-related time use competence was developed. This then served as a guiding concept for the understanding of time used in this work and as the overall objective for the educational intervention developed and piloted as part of the research. Next, a content analysis of German curricula was conducted with the aim of determining whether and to what extent these address the relation between time and sustainability. The results show curricula contain only a few starting points that encourage a connection between time and sustainability in school lessons. The study further indicates that an understanding of time as a scarce resource to be used efficiently has prevailed in school contexts so far. Accordingly, pedagogical approaches to time often focus heavily on time management. The next step involved developing and piloting a time use competence curriculum in cooperation with three partner schools, using an Action Research Approach. This intervention followed the pedagogical approach of Self-Inquiry Based Learning (SIBL) seeking to sensitise learners to the relation between individual needs and consumer behaviour. During implementation, which lasted one semester, students logged their time, were encouraged to reflect on their personal needs, and subsequently implement individual change projects related to time use. This was embedded in continuous reflective individual and group exercises. The results strengthen the hypothesis that there is a relation between time use and sustainability. Furthermore, the pedagogical approach of SIBL has proven suitable to enable students to reflect on their time use and to raise their awareness of the role of individual needs. Participants reported that changes in time use did indeed increase their personal well-being. This, according to existing evidence from sustainability science, has been found to potentially lead to more sustainable behaviour. At the same time, previous research found that behavioural changes that lead to an increase in well-being do not automatically lead to more sustainable consumption behaviour. Rather, personal attitudes and motivation regarding sustainability are important. This suggests that future ESE interventions aiming at changes in time use should always also contain sufficient opportunities for reflection of values and motives. A third empirical study was carried out, inquiring into students’ time use during the eriod of COVID-19-induced school closures, using a Grounded Theory Approach. Since the pandemic disrupted young peoples’ routines drastically, the research focused on which kinds of learning experiences students made during this time and which insights can be derived for ESE. The results of the semi-structured interviews with 69 participants show first that the narrative of students’ learning loss, which is predominant in the current educational science, policy, and media discussion, falls short. Instead, a variety of learning experiences are revealed, such as learning one’s own learning and everyday rhythms or creatively adapting consumption habits to the new situation of “lockdown”. Overall, a key finding of this work is that students are currently unable to adequately realise their time-related needs. In view of the findings from research on time and sustainability, one recommendation is therefore that everyday school life could give students more space to organise their time according to their needs. This might be done through pedagogical measures in the classroom, but would also require a stronger institutional anchoring, for example, within the framework of the Whole Institution Approach to Sustainability (WIA), to bring about lasting changes. Furthermore, it would be advisable to give the topic of time in connection with sustainability more space in curricula and in teacher training. This gives rise to future research needs, such as the need to explore how time use competence can be included into everyday pedagogical practice, for instance, by adapting the SIBL approach piloted in a school setting here. It would also call for longitudinal research designs, and it would be of interest to research how time use competence might be incorporated into school development processes. Given the ongoing debate about the impact of the COVID-19 pandemic on schools and education in general, the findings of the research can stimulate both further research and future ESE practice. The experiences during the pandemic have shown that schools and all actors involved including students and teachers, are so far insufficiently prepared to handle crises. Here, the approach to time use competence piloted in this work can offer valuable stimulations for ESE research and practice. This is especially true since it is compatible with existing approaches to key competencies for sustainability by seeking to complement them with a stronger focus on individual, needs-oriented time shaping.

Ein- und Zweifamilienhäuser sind in Deutschland die meistgefragte Wohnform und werden gemäß Prognosen auch in naher Zukunft fester Bestandteil der Neubautätigkeit bleiben. Gleichzeitig mahnen Ökologen und Stadtplaner seit längerem die Schwachpunkte der Typologie an und kritisieren beispielsweise die Zerschneidung der Landschaft, den hohen Flächenbedarf und die damit einhergehende Bodenversiegelung. Entgegen dieser Kritikpunkte zeigen andere Studien jedoch auch ökologisches Potenzial von Ein- und Zweifamilienhäusern auf. Beispielsweise können Hausgärten bei entsprechender Gestaltung zum Erhalt der Biodiversität beitragen und die Konnektivität von Habitaten verbessern. Vor diesem Hintergrund analysiert die vorliegende Arbeit die Potenziale der Typologie Ein- und Zweifamilienhaus auf Basis des Cradle to Cradle (C2C) Prinzips. Ziel der Arbeit ist es, die Umsetzbarkeit eines positiven Fußabdrucks nach C2C zu untersuchen. Als Betrachtungsgegenstand werden Ein- und Zweifamilienhäuser in Holzfertigbauweise gewählt, da sich durch die vertragsrechtliche Sonderstellung des Fertighausherstellers als Generalunternehmer und deren interne Entwicklungsabteilungen die Möglichkeit zur ganzheitlichen Umsetzung eines positiven Fußabdrucks ergibt. Zudem nahm der Anteil von Fertighäusern unter den genehmigten Ein- und Zweifamilienhäusern in den letzten Jahren stetig zu und betrug im Jahr 2019 circa 21 Prozent. Davon entfällt der weitaus größte Teil auf Holzbauweisen. Darüber hinaus wird in der vorliegenden Arbeit untersucht, ob durch die Anhebung der Ziele des nachhaltigen Bauens C2C Gebäude geschaffen werden können. In Verbindung damit wird diskutiert, ob gesetzliche Anreize zur Änderung des Bewusstseins aller Baubeteiligten – weg von der Minimierung negativer Auswirkungen im Sinne der Ökoeffizienz hin zu einem positiven Fußabdruck im Sinne der Ökoeffektivität – führen können. Die Untersuchung des Zusammenhangs zwischen nachhaltigem Bauen und C2C im Bauwesen erfolgt anhand eines Vergleichs verschiedener C2C Leitfäden und der C2C Produktzertifizierung mit Nachhaltigkeitsbewertungssystemen für kleine Wohngebäude. Wie auch bei der Frage nach dem positiven Fußabdruck, stehen dabei die Themen kreislauffähige Materialien, Rückbaupotenziale, Innenraumluftqualität, Wasserkreisläufe, Nutzung erneuerbarer Energien und Förderung von Biodiversität im Vordergrund. Die Umsetzbarkeit eines positiven Fußabdrucks wird anhand verschiedener Fallstudien untersucht. Diese umfassen C2C inspirierte Einfamilienhäuser sowie Ein- und Zweifamilienhäuser in Holzfertigbauweise, die nach dem Bewertungssystem Nachhaltiger Kleinwohnhausbau (BNK) zertifiziert wurden. Für eine vertiefte Analyse der Themen kreislauffähige Materialien und Rückbaupotenziale werden der Rückbau eines Einfamilienhauses in Holzfertigbauweise und die Versetzung eines Zweifamilienhauses in Holzfertigbauweise begleitet und ausgewertet. Die Untersuchung wird durch die Zerlegung eines Außenwandelements in Holztafelbauweise und die Bewertung dessen Trennbarkeit und Verwertbarkeit ergänzt.

Die negativen Auswirkungen des modernen Konsumverhaltens sind heute weithin bekannt, dennoch ist insbesondere die Modebranche weiterhin durch sehr niedrige Preise, kurze Produktlebensdauer und Massenkonsum gekennzeichnet. Die Folgen für Mensch und Umwelt sind gerade in der Kleidungsindustrie frappierend. Eine Veränderung des Konsumverhaltens in der breiten Bevölkerung hin zu einer Reduktion von Neukäufen, einer langen Nutzungsdauer der vorhandenen Kleidung und zum Kauf ökologisch und sozial verträglich hergestellter Produkte ist somit dringend notwendig. Ein wichtiger Erfolgsfaktor für die effektive Ansprache der Konsumierenden durch nachhaltiges Marketing von NGOs oder entsprechende Unternehmen ist die Berücksichtigung handlungsrelevanter Persönlichkeitsmerkmale aufseiten der Zielgruppe. Die wissenschaftliche Literatur zu Prädikatoren nachhaltiger Verhaltensweisen weist darauf hin, dass persönliche Werte eine wichtige Rolle für dessen Umsetzung spielen. Gleichzeitig wirkt sich insbesondere im Kleidungskonsum auch das Geschlecht bzw. Gender der/des Konsumierenden auf das Verhalten aus. Es existieren zahlreiche Hinweise darauf, dass das Geschlecht bzw. Gender zudem im Zusammenhang mit den Werteprioritäten einer Person steht. Ausgehend von dieser Datenlage werden in dieser Arbeit drei Themen mit Relevanz für die Nachhaltigkeitsforschung – persönliche Werte, Geschlecht/Gender und nachhaltiger Kleidungskonsum – zusammengeführt und auf ihre komplexe Wirkungsbeziehung hin untersucht. Auf Grundlage von Fokusgruppeninterviews wird erforscht, welche individuellen Wertorientierungen sich in welcher Weise und welcher Konstellation positiv auf ein nachhaltiges Kleidungskonsumverhalten auswirken und welche geschlechterspezifischen Unterschiede hierbei erkennbar werden. Durch die Berücksichtigung persönlicher konsumrelevanter Motivatoren und deren individueller Ausprägung werden Potenziale für eine zielgerichtete Verstärkung nachhaltigen Konsumverhaltens in der breiten Bevölkerung aufgedeckt. Dazu werden (1) vier Wertorientierungen mit Einfluss auf nachhaltigen Kleidungskonsum identifiziert, (2) ihre kausale Beziehung zu nachhaltigem Kleidungkonsum analysiert, (3) die geschlechtlichen Unterschiede berücksichtigt und (4) mit Gender ein Ansatzpunkt für die Erklärung der gefundenen Unterschiede angeführt. Zur Aufarbeitung der Daten wird die fsQCA zur Untersuchung des Themas nachhaltiger Kleidungskonsum angewandt. Die Natur dieser Auswertungsmethode, welche statt kausaler unidirektionaler Zusammenhänge zwischen zwei Variablen Schnittmengen zwischen zwei oder mehr Phänomenen untersucht, trägt zu einer neuen Perspektive auf die Beziehung zwischen Werten und nachhaltigem Kleidungskonsum bei. Eine wichtige Forschungsleistung dieser Arbeit besteht darin, gerade das Zusammenspiel der verschiedenen Werte zu betrachten und damit ein tieferes Verständnis von wichtigen Einflussfaktoren für nachhaltigen Kleidungskonsum zu ermöglichen. Dies ist ein Ansatz, welcher über die bisher existierenden Forschungserkenntnisse hinausgeht und für zukünftige Forschungsvorhaben zu Motiven für nachhaltigen Konsum hilfreich sein kann. Aus den gewonnenen Erkenntnissen werden Handlungsempfehlungen für die Kommunikation von NGOs und Unternehmen mit nachhaltiger Ausrichtung abgeleitet, wie eine zielgerichtete Ansprache zur Intensitätssteigerung dieser bereits vorhandenen Bedingungen gestaltet werden kann.

Kinder werden häufig vor Fremden gewarnt, die sie auf dem Nachhauseweg ansprechen. Doch wie steht es um Fremde, die sich im Netz hinter dem Profil eines Kindes verstecken? Vor dem Hintergrund steigender Fälle von Cybergrooming war es Ziel dieser Pilotstudie, eine Bestandsaufnahme über das Vertrauen von Kindern der dritten und sechsten Klasse in „gleichaltrige“ Fremde im Internet zu geben. Darüber hinaus gewährt die Studie Einblicke in Erfahrungen, die Kinder mit Fake-Profilen, sprich Profilen mit unwahren Identitätsinformationen, gemacht haben. Der Versuchsaufbau folgte einem 2 x 2-faktoriellen quasiexperimentellen Design mit dem Zwischensubjektfaktor „Alter“ (3. Klasse vs. 6. Klasse) und dem Innersubjektfaktor „Ort des Kontakts“ (offline vs. online). Die Stichprobe bildeten 58 Schüler:innen der dritten (n = 31) und sechsten Klasse (n = 27). Es wurde ein Fragebogen genutzt, der die Bewertung der Vertrauenswürdigkeit der Fremden, das Vertrauen in deren Identitätsinformationen sowie Erfahrungen mit Fake-Profilen erfasste. Die Ergebnisse zeigen, dass Kinder Fremde online als signifikant weniger vertrauenswürdig einschätzen im Vergleich zu Fremden offline. Darüber hinaus vertrauten dem Online-Fremden die älteren Sechstklässler:innen signifikant weniger als die Drittklässler:innen. Fast jedes zweite Kind gab Erfahrung mit Fake-Profilen an, jedoch wurden nur wenige geeignete Erkennungsmerkmale für diese genannt. Aus den Ergebnissen lässt sich ableiten, dass Kinder bereits um die Gefahr von Fake-Profilen wissen, allerdings scheinen sie teilweise ratlos zu sein, wenn es um deren Erkennung geht. Die Studie bietet einige Ansatzpunkte für zukünftige Forschung, die zum Abschluss diskutiert werden.

Die Einführung von Industrie 4.0 und der damit verbundene Wandel des Produktionsumfeldes führen zu neuen Herausforderungen, bieten auf der anderen Seite aber auch neue Möglichkeiten für Unternehmen. Ausgehend von den Herausforderungen der Produktionsplanung und Steuerung als zentrales Element der Produktherstellung, z.B. Komplexität, Dynamik und neue Organisationsformen, werden bestehenden Methoden der Reihenfolgeplanung auf ihre Tauglichkeit zur Verwendung hin geprüft. Die Analyse zeigt, dass Aspekte wie die Ableitung von Handlungen und der Transfer von Wissen in unbekannten Situationen zu den größten Herausforderungen für bestehende Verfahren zählen. Die in der Arbeit neu entwickelte Methode zur dynamischen Auswahl und Anpassung von Reihenfolgeregeln in komplexen Fertigungssystemen mit bestärkendem Lernen greift diese Herausforderungen auf und untersucht mögliche Lösungsstrategien. Die im Rahmen der Arbeit neu entwickelte Methode wird über ein Spektrum an unterschiedlichsten Szenarien evaluiert und mit anderen Methoden verglichen. Dabei werden verschiedene Ausprägungen und Komplexitäts-Niveaus von Handlungen, der Beobachtungsraum und die Mengen an benötigten Daten detailliert analysiert. Schlussendlich zeigt sich, dass die neue Methode in der Lage ist, die Anforderungen an die Produktionsplanung- und Steuerung zu erfüllen und in bekannten wie in unbekannten Szenarien gut Leistung zu erbringen. Zusätzlich ist die Methode in der Lage menschenähnliche Leistungen zu bringen und kann in einem realen Anwendungsfall zur Unterstützung der Produktionsplanung und -Steuerung genutzt werden.

Angststörungen gehören im Kindes- und Jugendalter zu den häufigsten psychischen Störungen. Sie führen zu mittel- und langfristigen psychosozialen individuellen und gesellschaftlichen Beeinträchtigungen und Belastungen, sind entwicklungspsychopathologisch verbunden mit Defiziten in der Emotionsregulation, zeigen eine hohe Komorbidität mit anderen psychischen Störungen wie insbesondere mit depressiven Störungen und weisen zudem eine hohe Rezidiv- und Persistenzneigung sowie eine niedrige Remissionswahrscheinlichkeit auf. Auf dieser Grundlage kommt der Prävention von Angststörungen bei Kindern und Jugendlichen eine besondere Bedeutung zu. Aufgrund eines konstatierten Forschungsdefizits im Zusammenhang mit universeller Angstprävention im Kindes- und Jugendalter ist im Kontext dieser Dissertation das Trainingsprogramm „Super Skills for Life“ von Essau & Ollendick evaluiert worden. Dabei ging es insbesondere um die Überprüfung eines Treatment-Effektes. Das „Super Skills for Life“-Programm ist ein CBT-geführtes Modell, das neben Exposition auch Methoden der Entspannungstherapie und des sozialen Kompetenztrainings impliziert. Als Resilienzaufbauprogramm zeichnet es sich besonders durch die Anwendung der Videofeedbackmethode aus. Im Kontext der schulbasierten Evaluation wurde eine zweifaktorielle Varianzanalyse mit Messwiederholung (Follow-Up-Messung nach sechs Monaten) unter Einbezug von Kovariaten (Bildung, Klassenstufe und Familienstand) und zusätzlich unter Berücksichtigung von Post hoc-Tests (Geschlecht) durchgeführt. Innerhalb der Stichprobe von Grundschulkindern nahmen an der Interventionsgruppe n=77 und an der Kontrollgruppe n=87 Probanden teil. Im Ergebnis konnten in der Zusammenfassung im Wesentlichen keine ausreichenden signifikanten Effekte des Programms hervorgebracht werden, somit konnte kein Treatment-Effekt belegt werden. Abschließend für diese Dissertation wurden Limitationen dieser empirischen Untersuchung wie bspw. die fehlende Randomisierung, der geringe Stichprobenumfang und der einschränkende Regionalitätsbezug diskutiert.

Mit der Digitalisierung geht eine Entgrenzung der Öffentlichkeit einher. Medientechnologien stellen nicht nur Möglichkeitsräume bereit, in denen Konflikte verhandelt werden. Sie transformieren auch den politischen Diskurs. Vor allem »die sozialen Medien« werden oft als Bedrohung einer konstruktiven Debattenkultur betrachtet. Die Beiträger*innen treten einen Schritt zurück und fragen aus sozial-, kulturwissenschaftlicher und philosophischer Perspektive, wie Öffentlichkeiten hergestellt und transformiert werden. Sie erörtern theoretische sowie empirische Perspektiven und analysieren normative Fragestellungen, die angesichts globaler Dynamiken und neuer Formen von Kulturkonflikten an Bedeutung gewinnen.

Stretching is primarily used to improve flexibility, decrease stiffness of the muscle- tendon unit or reduce risk of injury. However, previous animal studies from 1970 to 1990 showed significant hypertrophy effects in skeletal muscle in response to chronic stretching intervention with stretching durations of 30 minutes to 24 hours per day. However, no study in humans was performed using comparatively long stretching durations of more than 30 minutes per day with a daily frequency. The present cumulative dissertation includes six studies aiming to investigate the effects of long-lasting static stretching training on maximum strength capacity, hypertrophy and flexibility in the skeletal muscle. Before starting own experimental studies, a meta-analysis of available animal research was conducted to analyze the potential of long-lasting stretching interventions on muscle mass and maximum strength. To induce long-lasting stretching on the plantar flexors and to improve standardization of the stretch training by quantifying the angle in the ankle joint while stretching, a calf muscle stretching orthosis was developed. In the following experimental studies, the orthosis was used to induce daily long- lasting static stretching stimuli with different stretching durations and intensities in the plantar flexors to assess different morphological and functional parameters. For this, a total of 311 participants were included in the studies and, dependent on the investigation, the effects of daily stretching for 10-120 minutes for six weeks were analyzed. Therefore, effects on maximal isometric and dynamic strength as well as flexibility of the plantar flexors were investigated with extended and flexed knee joint. The investigation of morphological parameters of the calf muscle was performed by determining the muscle thickness and the pennation angle by using sonographic imaging and the muscle cross-sectional area by using a 3 Tesla magnetic resonance imaging measurement. In animals, the included systematic review with meta-analysis revealed increases in muscle mass with large effect size (d = 8.51, p < 0.001), muscle cross-sectional area (d = 7.91, p < 0.001), fiber cross-sectional area (d = 5.81, p < 0.001), fiber length (d = 7.86, p < 0.001) and fiber number (d = 4.62, p < 0.001). The thereafter performed experimental studies from our laboratory showed a range of trivial to large increases in maximum strength of 4.84% to 22.9% with d = 0.2 to 1.17 and ROM of 6.07% to 27.3% with d = 0.16 to 0.87 dependent on stretching time, training level and testing procedure. Furthermore, significant moderate to large magnitude hypertrophy effects of 7.29 to 15.3% with d = 0.53 to 0.84 in muscle thickness and trivial to small increases of 5.68% and 8.82% (d = 0.16 to 0.3) in muscle crosssectional area were demonstrated. The results are discussed based on physiological parameters from animal studies and in the front of knowledge in resistance training, suggesting mechanical tension to be one important factor to induce muscle hypertrophy and maximal strength increases. Further explanatory approaches such as hypoxia and changes in the muscle tendon unit are debated in the following. Since these studies are the first investigations on long-lasting stretch-mediated hypertrophy in humans, further research is needed to explore the underlying mechanisms and confirm the results in different populations to enhance the practical applicability for example in clinical populations when, e.g. counteracting muscular imbalances or sarcopenia in the elderly.

Climate change presents a major sustainability challenge to coastal social-ecological systems (SES). The integration of climate change adaptation into processes or structures for coastal governance, however, has been described as challenging. Resilience presents a suitable concept to approach this problem, as it facilitates bridging between the natural and social sciences, as well as between science and policy in an inter- and trans-disciplinary approach. The Intergovernmental Panel on Climate Change also makes use of the concept of resilience and confirms that recent literature increasingly suggests that transformative changes in SES are required to enhance their resilience to climate change. Yet, knowledge gaps still exist on how to enable effective coastal governance to enhance the climate resilience of coastal SES. To address this problem, the importance of actionable knowledge is growing in climate change adaptation, environmental governance, and broader sustainability research. Actionable knowledge refers to knowledge that contributes to solving societal problems and points to actions and processes of change. One way of generating actionable knowledge is the co-production of knowledge with societal stakeholders. Yet, knowledge gaps exist in what methods and approaches may contribute to generating actionable knowledge and what obstacles to knowledge co-production exist especially for early-career researchers (ECRs). This dissertation contributes to research on generating actionable knowledge for coastal governance to enhance the resilience of coastal SES to climate change. It does this by providing theoretical, methodological and empirical insights on three research questions (RQs), laid out in Chapter I. These are: 1) what is a more actionable concept for applying the concept of resilience in coastal governance?; 2) what methods and approaches are suitable to generate actionable knowledge for coastal governance?; and 3) what obstacles to knowledge co-production exist for ECRs and how can they be overcome? The RQs are addressed in five publications, each presenting one chapter of this dissertation. For answering RQ1, Chapter II applies a research synthesis to bring together common themes and challenges documented in resilience, climate change and environmental governance literature. For answering RQ2, in Chapter III-V different methods and approaches for generating actionable knowledge are proposed and tested using a case-study in the SES of Algoa Bay, South Africa. These include i) the analysis of stakeholder agency as an indicator of the ability of stakeholders to act in governance processes; ii) the application of a stakeholder analysis to gain an improved understanding of the current degree of knowledge exchange for climate change adaptation; and iii) the combination of a capital approach framework, and fuzzy cognitive mapping, which shed light on the governance performance for climate change adaptation and on leverage points that can enhance climate resilience. Finally, for answering RQ3, Chapter VI provides a perspective on the obstacles that especially ECRs face, and actions that are needed to create the conditions under which knowledge co-production processes can be successful. This is done by applying a multi-method approach combining an online survey and workshop targeted at ECRs in the marine sciences. Key findings suggest that system and transformative knowledge are particularly important when applying the concept of resilience in coastal governance to generate actionable knowledge. The different methods and approaches that are proposed and tested contribute to generating both system and transformative knowledge. Firstly, they provide an overview of the capacities of different stakeholders to act, shed light on current collaboration and knowledge exchange, and enable the identification of different governance processes for coastal governance and climate change adaptation (system knowledge). Secondly, results have implications for how to improve knowledge exchange and identify leverage points that can enhance overall governance performance, thus providing recommendations on actions and processes that can enhance climate resilience in the case-study area (transformative knowledge). It is also highlighted how knowledge co-production can contribute to generating system and transformative knowledge together with stakeholders, and what actions are needed to build the capacities to translate knowledge into action. Additionally, the findings of this dissertation put forward actions that are needed at different organisational levels of the academic system to facilitate knowledge co-production processes with stakeholders involved in coastal governance. The results of this dissertation have implications for stakeholders and decision-making in the case-study area, as well as for environmental governance, climate change adaptation and broader sustainability research. Implications for stakeholders include recommendations for implementing formal commitments to share climate information across levels and sectors, establishing the role of information providers in the municipality, and reinforcing human capital within the local municipality in Algoa Bay. It also requires more support from the provincial government, such as addressing funding issues, offering training focusing on stakeholders with lower agency and capacities, and improving the overall availability and accessibility of climate information, as well as the priority given to climate change in the Integrated Development Plan. Findings also suggest the need for a more integrated approach to climate change adaptation in coastal planning and management frameworks. It also suggests that the conservation of environmental assets presents an important bottleneck for resilience management and needs to be further prioritised within decision-making. Implications for research include the applicability of methods beyond the context of this dissertation; a more actionable concept for approaching resilience in (coastal) governance systems that can be applied for achieving broader sustainability goals; and a more critical reflection on how transformative research is conducted, and what academic foundation is needed so that it can fulfil its societal goal. Future research may include a combination of the methods applied in this dissertation; qualitative applications of the stakeholder network analysis; and an application of the proposed approach to other case-studies using real-world laboratories. Overall, this dissertation provides theoretical, methodological, and empirical implications and insights into pressing SES problems. It also contributes to advancing the field of transformative research for more societally relevant outcomes in face of climate change and broader sustainability challenges

How can CSX be applied to different industries in the cultural field? The following three subchapters discuss general problems of the cultural sector (the past), current practice examples of CSX (the present) and visions about new possibilities in this sector (the future), envisioning the progress of the sector through the implementation of CSX as an alternative economic model. This chapter explores this by using creative writing styles. While all the characters are fictional, the characterizations and the outline of the story draw from our scientific research. Our main protagonist is Quinn who studies Cultural Studies, is a volunteer in several cultural initiatives and works at a podcast studio. Planning to be done with the Master's program in about a year, questions about possibilities of a future employment in the cultural sector are becoming more present for Quinn and their fellow students.

In this chapter, we aim to present how shame, vulnerability, self-care and community care interrelate to one another and how they help build the necessary foundation for mutual care in interdependent communities, and thus for community-supported projects (CSX). Furthermore, we argue that by looking at the role of shame and vulnerability within our personal life, as we simultaneously learn to take care of ourselves, we then lay a solid foundation for learning how to support others. We then suggest that at the birthplace between healthy sustainable self-care and community care, people and communities are able to shift from a hyper-individualized lifestyle (isolation, disconnection) to a more collective community-centered approach (belonging and connection) that finally creates the perfect recipe for the creation of CSX Projects and a more inclusive and kinder economy for all.

The computational analysis and the optimization of transport and mixing processes in fluid flows are of ongoing scientific interest. Transfer operator methods are powerful tools for the study of these processes in dynamical systems. The focus in this context has been mostly on closed dynamical systems and the main applications have been geophysical flows. In this thesis, we consider transport and mixing in closed flow systems and in open flow systems that mimic technical mixing devices. Via transfer operator methods, we study the coherent behavior in closed example systems including a turbulent Rayleigh-Bénard convection flow and consider the finite-time mixing of two fluids. We extend the transfer operator framework to specific open flows. In particular, we study time-periodic open flow systems with constant inflow and outflow of fluid particles and consider several example systems. In this case, the transfer operator is represented by a transition matrix of a time-homogeneous absorbing Markov chain restricted to finite transient states. The chaotic saddle and its stable and unstable manifolds organize the transport processes in open systems. We extract these structures directly from leading eigenvectors of the transition matrix. For a constant source of two fluids in different colors, the mass distribution in the mixer and its outlet region converges to an invariant mixing pattern. In parameter studies, we quantify the degree of mixing of the resulting patterns by several mixing measures. More recently, network-based methods that construct graphs on trajectories of fluid particles have been developed to study coherent behavior in fluid flow. We use a method based on diffusion maps to extract organizing structures in open example systems directly from trajectories of fluid particles and extend this method to describe the mixing of two types of fluids.

In past digital health interventions, an issue has been that participants drop out over time which is referred to as the ”law of attrition” (Eysenbach, 2005). Based on this, we propose that though initially, participants respond to the intervention, there is a hypothesized second diminishing e↵ect of an intervention. However, we suggest that on top, there is a third e↵ect. Independent of the individual notification or nudge, people could build the knowledge, skills and practice needed to independently engage in the behavior themselves (schraefel and Hekler, 2020). Using behavioral theory and inspired by prior animal computational models of behavior, we propose a dynamical computational model to allow for a separation of intervention and internalization. It is targeted towards the specific case of the HeartSteps intervention that could not explain a diminishing immediate effect of the intervention, second hypothesized e↵ect, while a person’s overall steps remained constant, third e↵ect (Klasnja et al., 2019). We incorporate a habituation mechanism from learning theory that can account for the immediate diminishing e↵ect. At the same time, a reinforcement mechanism allows participants to internalize the message and engage in behavior independently. The simulation shows the importance of a participant’s responsiveness to the intervention and a sufficient recovery period after each notification. To estimate the model, we use data from the HeartSteps intervention (Klasnja et al., 2019; Liao et al., 2020), a just-in-time adaptive intervention that sent two to five walking suggestions per day. We run a Bayesian estimation with Stan in R. Additional validation tests are needed to estimate the accuracy of the model for di↵erent individuals. It could however serve as a template for future just-intime adaptive interventions due to its generic structure. In addition, this model is of high practical relevance as its derived dynamics can be used to improve future walking suggestions and ultimately optimize notification-based digital health interventions.

The research described in this dissertation focuses on developing a process to remove oligomers and suppress their formation by intercepting the aging procedure's precursors using adsorbents when biodiesel and its blends are used as fuel. There has been the search for various energy sources due to the increasing awareness of the depletion of fossil fuel resources, environmental issues, and more urgently is the need to mitigate climate change. Biodiesel has become more attractive in recent times (Daming et al. 2012, Abdullah et al., 2007) as an alternative fuel. Biodiesel, a methyl ester of vegetable oil, is a renewable, low environmental impact, green alternative fuel for diesel engines (EU Regulation, 2012, Ghosh and Dutta, 2012). In addition to its renewable status, biodiesel, compared to fossil fuel, has advantages such as its biodegradability, reduced exhaust emissions, higher cetane number, lubricity, and safer distribution and storage due to its higher flash point (Pereira et al. 2015, Monyem and Van Gerpen, 2001). Biodiesel fuel is chemically fatty acid methyl ester (FAME) derived from different plant oils. It varies slightly in molecular structures due to the degree of unsaturation of the fatty acids in the different sources compared to conventional diesel fuel (Pereira et al. 2015, 2013, Sharma and Singh, 2009). Biodiesel fuels contain significant amounts of esters of oleic, linoleic, or linolenic acids, which influence their oxidative stability. A small percentage of more highly unsaturated fatty compounds have a disproportionately strong effect in reducing oxidation stability and promoting oligomers formation. The oxidation products of the biodiesel in the engine sump influence the degradation of the lubrication oil.

Globalization has increased the speed, volume and spatial scale of global flows of people, information, finance, goods and services. Economic globalization is closely linked to the globalization of environmental problems, with the underlying causes and directly visible effects of environmental problems becoming increasingly geographically dispersed. For example, the products consumed in one place can have negative environmental effects in distal places of production. This poses challenges to territorially-based governance systems. Governments do not have legal authority to regulate environmental problems in other jurisdictions, even if their own policies or actions of domestic companies contribute to these problems. Likewise, companies face challenges with overseeing and governing the environmental effects that occur along their supply chains. Nevertheless, state and non-state actors increasingly aim to govern environmental problems outside their jurisdictional and organizational boundaries that arise from long-distance interactions between social-ecological systems – so-called telecoupled systems. This doctoral dissertation analyses the environmental governance of long-distance social-ecological interactions in telecoupled systems in two issue domains: global commodity chains and infrastructure projects as part of China’s Belt and Road Initiative (BRI). Although both domains involve different governance actors, institutions and processes, they both concern the question of how the involved actors develop governance structures and institutional responses to telecoupling. This dissertation aims to contribute to a deeper understanding of how to govern environmental problems that are associated with global flows. Since many multilateral environmental governance initiatives have not yet produced the desired solutions to global problems, particular attention is directed at unilateral state-led governance approaches. This dissertation addresses the questions of (1) how to achieve a spatial fit between the scale of telecoupled systems and the scale of governance institutions, (2) how governance actors exercise agency in governing telecoupled systems, and (3) how state actors can govern the domestic and foreign environmental effects of telecoupled flows. This dissertation draws upon, and contributes to, two fields of research: research on telecoupling and research on global environmental governance. The results show that creating a spatial fit in the governance of global commodity flows is challenging because boundary and resolution mismatches can emerge. Boundary mismatches denote situations where social-ecological problems transcend established jurisdictional boundaries, whereas resolution mismatches refer to governance institutions that have too coarse a spatial resolution to allow them to address the specific aspects of social-ecological problems effectively. No single governance institution is likely to avoid all mismatches, which highlights the need to align multiple governance approaches to effectively govern telecoupled systems. 2 Telecoupled flows are often governed at places where they originate and places where they arrive for processing, final consumption, or investment. If governance in the jurisdiction experiencing the environmental issue is weak, external governance actors can aim to fill this governance gap by introducing due diligence legislation and by promoting sustainability standards in international (trade) relations. State actors often rely on the actions of non-state actors to govern beyond jurisdictional borders. Despite efforts to govern environmental outcomes in distant jurisdictions, it is important to recognize the agency of governments that experience the direct environmental effects of telecoupling. They have great leverage to steer telecoupled systems towards sustainability through the formulation, implementation, monitoring and enforcement of stringent regulatory frameworks, in the context of both commodity supply chains and BRI projects. The findings of this dissertation are relevant for scholars and policy makers interested in what can be termed external environmental governance, which refers to the governance structures and institutions to shape environmental outcomes outside the borders of a given jurisdiction.

This dissertation deals with the increasingly recognized role of incumbent firms in advancing sustainability-oriented industry transitions. Incumbent firms are understood as firms-in-industries, which are embedded in established market structures and thereby contrast new entrant firms. The purpose of this research is twofold. First, to provide empirical evidence of barriers to and success factors of incumbent-driven industry transitions. Second, to unify hitherto dispersed descriptions of transition-related firm behaviour in a new understanding of incumbent firms in industry transitions. To this end, theoretical concepts are discussed and extended on the basis of different empirical studies in the German meat industry. The meat industry serves as suitable research setting due to its diverse sustainability challenges, ranging from climate change and pollution to animal welfare and public health, as well as its current developments towards sustainable protein alternatives. The meat context also offers opportunities to delve into individual-level processes influencing transition-related behaviour. The main contribution of this dissertation is a Multi Embeddedness Framework (MEF) that details processes and outcomes of integrated incumbent firm behaviour, including passive, reactive and proactive behaviors. The framework acknowledges the diversity in incumbent firm behaviors within industries and firms and provides new insights into transition-related behaviors at firm and individual level. With regard to the latter, the potential of learning about and from innovative start-up firms as well as shared sensemaking processes are discussed. The contents of this dissertation provide valuable contributions to the transition literature as well as important management implications with regard to the stimulation and promotion of proactive behaviors

This research argues that the emergent driverless car, as a kind of autonomous vehicle, is a Foucault-ian ‘ethical apparatus’, working as an epistemic device to materially embody and enable discursive power by generating notions of ‘autonomy’ and ‘ethical decision-making’. The ethical implications of AI, algorithmic, and autonomous technologies are topics of current regulatory and academic concern. This concern relates to the lack of meaningful oversight of black boxes inside AI systems, liabilities for manufacturers, and inadequate frameworks to hold AI-based socio-technical systems to account. One recent artefact, the driverless car, has taken on these concerns quite literally in the shaping of a niche discourse of the ‘ethics of autonomous driving’. Ambitions to produce a fully autonomous vehicle based on AI technologies are constrained by speculative concerns that its decision-making in unexpected accident situations cannot be assumed to protect humans. ‘The ethics of autonomous driving’ evaluates proposals to build ‘ethical machines’ by examining the relationship between structures of human values and moral decision-making, and how they comport to computational architectures for decision-making. This is the first case this work takes up, chiefly organised around an analysis of a thought experiment, the Trolley Problem, and the online game, Moral Machine, that crowdsourced values to suggest approaches to an ‘ethics of autonomous driving’. Rather than evaluate the feasibility or appropriateness of these two approaches, this work attends to the more critical issue that ethics is being proposed in terms of technologies turning on the logics of risk, speculation, and probabilistic correlations that are fundamental to how machine learning makes decisions. The concern in this work is less a normative framework or approach for a better or more appropriate ethics of autonomous driving. Rather, this work argues that what we understand as ‘the ethical’ is being transformed when architected by, through, and for AI/autonomous technologies to become their own regulators. Hence the production of autonomous driving necessitates computational infrastructures that are creating a world legible to and for the navigation of a driverless car. I argue that this is fostering computational governance that has implications for human bodies and social relations, chiefly that conventional approaches to regulation and accountability attend to human values and decision-making rather than computational ones. A second case that this research examines is that of driverless car crashes, to examine how ‘autonomous’ driving requires substantial embodied human knowledge and micro-work. Taken together, these two cases - the ethics of autonomous driving, and crashes - make an argument for how myriad practices of knowledge-production are translating the human world into something legible to the navigational needs of the car, producing changes in the human world through the actions of the car on that basis, and advancing notions of ‘autonomy’. This work concludes with arguments for a critical reconceptualisation of ethics and ethical decision-making in AI/autonomous systems.

In Deutschland herrscht wegen des Bundesstaatsprinzips Bildungsföderalismus. Gemäß dem Grundgesetz haben die Länder Kulturhoheit und gegenüber dem Bund eine überwiegende Zu-ständigkeit für Bildung, Wissenschaft und Kultur. Die 16 Bundesländer können ihre schulischen Bildungsangebote weitgehend eigenständig und unabhängig voneinander gestalten. Im Rahmen der Kultusministerkonferenz (KMK) findet eine Kooperation der Bundesländer statt, um in An-gelegenheiten von länderübergreifender Bedeutung grundlegende und notwendige Gemeinsam-keiten und Qualitätsstandards zu koordinieren. Dabei wird ein für alle Länder verbindlicher Rahmen festgelegt in Form von Beschlüssen, Empfehlungen, Vereinbarungen oder Staatsab-kommen. Für den Bereich der Schulen kann das Kultusministerium eines Bundeslandes als oberste Lan-desbehörde für Angelegenheiten der Bildung jedoch weitgehend in eigener Zuständigkeit allein entscheiden. So kann ein Bundesland z.B. eine neue Schulform einführen. In einzelnen Fällen wurden sogar landesspezifische neue Schulfächer zugelassen (z.B. das Fach „Wirtschafts-/ Be-rufs- und Studienorientierung“ in den Gymnasien Baden-Württembergs). Diese wurden von der KMK nach Prüfung gewisser Qualitätsstandards anerkannt. In diesem Bildungsföderalismus kommt in der Praxis ein großes Maß an Freiheit im Sinne von „Vielfalt im Bildungswesen” zum Ausdruck. Auch mit der kreativen Zielsetzung, „Raum für Innovationen“ zu lassen (KMK). Obwohl in den sechzehn Bundesländern in verschiedenen Aspekten der Bildungspolitik Unter-schiede bestehen, existiert im Hinblick auf die Schulfächer eine große Schnittmenge. So sind die Fächer Deutsch, Mathematik, Biologie, Geschichte, Erdkunde, Sprache(n), Sport, Musik, Politik oder Religion/Ethik in der Regel feste Bestandteile der Stundentafeln allgemeinbildender Schul-formen. Sie werden allen Schülerinnen und Schüler im Rahmen des Unterrichts von dafür uni-versitär ausgebildeten Fachlehrkräften verpflichtend vermittelt. ...

Die Gesundheit von Lehrkräften ist ein wichtiger Faktor für schulorganisatorische Aspekte (u. a. Berufswechsel, Fehlzeiten), die Lehrkraft-Schüler*innen-Interaktion (Klassenführung, Kognitive Aktivierung und emotionale Unterstützung) und die Motivation sowie die Leistungen von Schüler*innen. Werden Lehrkräfte im Schuldienst tagtäglich mit einer Vielzahl an beruflichen Herausforderungen konfrontiert, können diese bei mangelnden Ressourcen zu einem erhöhten Belastungserleben führen. Demnach sollten Lehrkräfte bereits in der Ausbildung ihre gesundheitsförderlichen Ressourcen stärken, um gesund in den Beruf zu starten. Dabei stellt sich die Frage, über welche Ressourcen angehende Lehrkräfte verfügen sollten, um trotz Herausforderungen gesund zu bleiben und wie diese in der Ausbildung gefördert werden können. Dem Konzept der Salutogenese folgend, widmet sich diese Arbeit der individuellen Gesundheitskompetenz von angehenden Lehrkräften, die als Schlüsselkompetenz verstanden wird um die körperliche und psychische Gesundheit zu stärken. Im Kontext der Lehrkräfteausbildung mangelt es an empirischen und auch konzeptuellen Studien, die die individuelle Gesundheitskompetenz in den Fokus nehmen. Entsprechend werden folgende Fragestellungen in dieser kumulativen Dissertation untersucht: Publikation 1: Die erste Studie widmet sich den Fragestellungen, wie die weiterentwickelten Fähigkeiten der individuellen Gesundheitskompetenz bei angehenden Lehrkräften ausgeprägt sind und welche Bedeutung diese für die Gesundheit von angehenden Lehrkräften haben. Dazu wurden Studierende aus dem 2. Mastersemester (195 Lehramtsstudierende vs. 108 Nicht-Lehramtsstudierende) befragt. Die Ergebnisse zeigen, dass sich Lehramtsstudierende im Vergleich zu Nicht-Lehramtsstudierenden signifikant besser in den Komponenten der Gesundheitskompetenz einschätzen, mit Ausnahme der Verantwortungsübernahme. Die niedrigsten Ausprägungen sind in beiden Gruppen in den Fähigkeiten zur Selbstregulation und Kommunikation und Kooperation aufzufinden. Hinsichtlich des allgemeinen Gesundheitszustandes unterscheiden sich die Studierendengruppen nicht signifikant voneinander, jedoch weist knapp jede*r dritte*r Studierende*r einen schlechten Gesundheitszustand auf. Dabei steht v. a. die Komponente Selbstregulation mit dem Gesundheitszustand in Beziehung. Publikation 2: Die zweite Studie geht ebenfalls den Fragestellungen nach, wie die weiterentwickelten Fähigkeiten der individuellen Gesundheitskompetenz bei angehenden Lehrkräften ausgeprägt sind und welche Bedeutung diese für die Gesundheit von angehenden Lehrkräften haben. Hierzu wurde jedoch in dieser Studie die Gesundheitskompetenz von Lehrkräften in der ersten (Lehramtsstudium) und zweiten Phase (Vorbereitungsdienst) der Lehrkräfteausbildung gemessen (195 Masterlehramtsstudierende vs. 242 Lehrkräfte im Vorbereitungsdienst). Lehramtsstudierende weisen im Vergleich zu den Lehrkräften im Vorbereitungsdienst signifikant höhere Werte in den übrigen Fähigkeiten der Gesundheitskompetenz auf mit Ausnahme der Fähigkeit zur Kommunikation und Kooperation. Die niedrigsten Ausprägungen sind in beiden Gruppen in den Fähigkeiten zur Selbstregulation und Kommunikation und Kooperation aufzufinden. Hinsichtlich des allgemeinen Gesundheitszustandes schätzen Lehrkräfte im Vorbereitungsdienst diesen signifikant besser ein als Lehramtsstudierende, wobei in beiden Gruppen insbesondere die Komponente Selbstregulation mit dem Gesundheitszustand korreliert. Die Ergebnisse multipler Regressionsanalysen zeigen, dass die Fähigkeiten zur Selbstregulation, Selbstkontrolle und Verantwortungsübernahme Prädiktoren für den Gesundheitszustand von Lehramtsstudierenden darstellen, und die Fähigkeiten zur Selbstregulation und Verantwortungsübernahme die Prädiktoren für den Gesundheitszustand der Lehrkräfte im Vorbereitungsdienst sind. Insgesamt verdeutlichen die Ergebnisse die Bedeutung der Gesundheitskompetenz für den Gesundheitszustand und verweisen auf die Forderung nach Interventionen zur Förderung der Gesundheitskompetenz, die insbesondere die Fähigkeiten zur Kommunikation und Kooperation und Selbstregulation fokussieren, wobei die Selbstregulation einen besonderen Stellenwert einnimmt. Publikation 3: In der dritten Studie wird vor allem untersucht wie die berufliche Selbstregulation mit den weiterentwickelten Fähigkeiten der individuellen Gesundheitskompetenz von angehenden Lehrkräften zusammenhängt und welche Komponenten die psychische Gesundheit von angehenden Lehrkräften bedingen. Dazu wurden 407 Lehrkräfte im Vorbereitungsdienst befragt. Die Selbstregulationstypen wurden mittels einer latenten Profilanalyse analysiert und die vier beruflichen Selbstregulationstypen repliziert (Gesundheitstyp: 35.4%, Schontyp: 22.8%, Typ A: 19.2% und Typ B: 22.6). Es zeigen sich Zusammenhänge zwischen den Subdimensionen der beruflichen Selbstregulation und den Komponenten Selbstkontrolle und Selbstregulation der Gesundheitskompetenz. Unabhängig voneinander hängt der Gesundheitstyp, Schontyp und Typ A sowie die Gesundheitskompetenzdimensionen Selbstregulation, Selbstkontrolle und Verantwortungsübernahme mit dem psychischen Wohlbefinden zusammen. Werden beide Ressourcen zusammen betrachtet, erklären die Komponenten der individuellen Gesundheitskompetenz mehr Varianz im psychischen Wohlbefinden als die Selbstregulationstypen. Aus den Ergebnissen kann abgeleitet werden, dass eine Lehrkräfteausbildung, die Aspekte der Selbstregulationsfähigkeit einbezieht, nicht nur das Wohlbefinden von angehenden Lehrkräften verbessern könnte, sondern auch ihre individuelle Gesundheitskompetenz. Eine Förderung der beruflichen Selbstregulation durch Lernangebote könnte auch mit der Stärkung der individuellen Gesundheitskompetenz von angehenden Lehrkräften verbunden sein. Publikation 4: In der vierten Studie wurden die empirisch gewonnenen Erkenntnisse der ersten drei Studie aufgegriffen und ein Seminarkonzept zur Förderung der individuellen Gesundheitskompetenz von angehenden Lehrkräften im Rahmen der Lehrkräfteausbildung erstellt. Das Seminar umfasst unter anderem allgemeine gesundheitswissenschaftliche Grundlagen und die theoretische Hinführung zu verhaltensbezogenen Bewältigungsstrategien, am Beispiel von Achtsamkeit, und verhältnisbezogenen Strategien im Kontext Schule mit Bezug zur Unterrichtsqualität und Schulentwicklung. Das Rahmenpapier bettet die vier Publikationen in den übergeordneten theoretischen Kontext ein, diskutiert die Ergebnisse und leitet abschließend Empfehlungen für weitere Forschung und für die Lehrkräfte(aus)bildung ab. Das Rahmenpapier schließt mit einem Fazit.
