Undertaking local actions, such as implementing public (sustainability) policy, plays a crucial role in achieving sustainable development (SD) at the municipal level. In this regard, indicator-based assessment supports effective implementation by measuring the SD process, based upon evidence-based outcomes that indicators produce. Over the last decade, using subjective indicators, which rely on an individual’s self-perception to measure subjects, has gained its significance in sustainability assessment, in line with the increasing importance of signifying individual’s and community’s well-being (WB) in the context of SD. This study aims to discuss and clarify the scope and functions of subjective sustainable development indicators (SDIs) conceptually and theoretically while examining the usability of such indicators employed in the practice of assessing sustainability policy and action process in a Japanese municipality. Furthermore, the potential usability of using subjective SDIs in monitoring a municipal initiative of the United Nations’ Sustainable Development Goals (SDGs) is also explanatorily examined. The present paper consists of a framework paper and three individual studies. In the framework paper, Section 1 introduces the global transition of SD discourse and the role that local authorities and implementing public policy play in achieving SD while outlining how WB positions in the SD context. Section 2 provides a brief overview of the major scope of overall SDIs at the conceptual and theoretical levels. Section 3 defines WB in the study’s own right while exploring the scope of indicators measuring WB. In addition, this study strives to further clarify the peculiar scope of SDIs, measuring WB by synthesising the findings. Section 4 overviews how SD at the municipal level in Japan is practiced while acknowledging the extent to which residents perceive WB and SDGs in policymaking. Section 5 provides a brief yet extensive summary of the three individual studies. Section 6 discusses the findings while presenting implications for further study and practices of subjective SDIs. Furthermore, the three individual studies provide a thorough and in-depth discussion of the study subject. Study 1 illustrates the SD trend at the municipal level in Japan and the growing recognition of using subjective SDIs in public (sustainability) policy assessment in exploring comparative SDI systems to municipality groups. The findings, in turn, raise the need for a further study on subjective SDIs. Study 2 extensively discusses the concept of WB as the overarching subject to be measured while examining varying approaches and scopes of SDIs. It identifies three differentiated WB (i.e., material and social objective WB as well as subjective WB) and distinctive approaches of subjective SDIs (i.e., expert-led and citizen-based approaches) alongside objective SDIs. The findings suggest that these SDIs identified are, conceptually, most capable of measuring associated WB; for instance, citizen-based subjective SDIs can most optimally measure subjective WB. Finally, Study 3 examines the usability of (citizen-based) subjective SDIs in a practice of assessing public policy, aiming at municipal SD, and the potential usability of using such indicators in monitoring a municipal SDG initiative. The findings highlight the determinants and obstacles of using subjective SDIs as well as signifying WB in measuring progress of a municipal SD practice.

Die Dissertation leistet einen Beitrag zur Erforschung der Schriften John Stuart Mills, indem darin Mills rudimentär ausformulierte Denkfigur und Forschungslücke der „Art of Life“ untersucht wird. Die Autorin erweitert die traditionelle Interpretation Mills als klassischem Utilitaristen um einen geschärften Blick auf Mills Handhabung des antiken Theorieelements der Tugend. Drei überlappende thematische Zugänge – Lust, Charakter, Glückseligkeit – dienen der Veranschaulichung und Stärkung der These, wonach es sich bei Mills Theorie um eine hedonistische, perfektionistisch gefärbte Theorie der guten Lebensführung handelt. Der methodische Rückgriff auf die Lust- und Glückskonzeption des Aristoteles erlaubt es Mills differenzierte Auffassung von Lust bzw. Freude zu ergründen, die Rolle des menschlichen Charakters für das (moralische) Handeln festzustellen und eudemische Spuren im Verständnis von Glück aufzudecken. Abschließend bietet die Dissertationsschrift eine Interpretation der Schriften Mills als Lebenskunstphilosophie mit moralischen und außer-moralischen Ebenen und zeigt Anschlusspotentiale zu antiken, sowie zeitgenössischen (Lebenskunst) Theorien auf.

Consisting of three articles and a framework manuscript, this cumulative dissertation deals with sustainable compensation of chief executive officer (CEO) with a focus on climate-related aspects. Against the backdrop of the European action for sustainability and the EU Green Deal, the dissertation pays special attention to the consideration of climate-related aspects of corporate performance in CEO compensation. In this context, sustainable compensation is characterized by the consideration of long-term interests and sustainability of the company as well as by the inclusion of financial and non-financial aspects of environmental, social and governance performance (ESG) in compensation agreements. While this novel instrument of corporate governance aims to incentivize the implementation of sustainability-oriented corporate strategy, it is particularly important to unfold this incentive effect at the individual CEO level in view of their managerial discretion. The framework manuscript discusses the research objectives, the regulatory and theoretical background, the results of the dissertation and their implications in the context of regulation, research, and business practice. The essence of the dissertation are the three articles. The first article, "Determinants and effects of sustainable CEO compensation: a structured literature review of empirical evidence," examines the current state of empirical research based on 37 articles that were published between 1992 and 2018. Based on a multidimensional research framework, the structured literature review compiles past research findings, identifies contentual and methodological foci in the research area, and derives questions for future research. The second article, "Mapping the determinants of carbon-related CEO compensation: a multidimensional approach," addresses the topic from a conceptual perspective. Taking the existing work as a starting point, a conceptual framework is derived, which organizes the determinants of carbon-related CEO compensation at societal, organizational, group and individual levels of analysis. On this basis, eight propositions are presented that seek to distinguish between the determinants which support and challenge the implementation of carbon-related CEO compensation. The third article, "Climate change policies and carbon-related CEO compensation systems: an exploratory study of European companies," focuses on the use of CO2-oriented performance indicators in CEO compensation. The empirical-qualitative study analyzes corporate disclosure of the 65 largest companies in the EU for the years 2018 and 2019. The study addresses the use of CO2-oriented performance indicators in corporate strategy and CEO compensation. It also examines which compensation components are determined with the help of CO2-oriented performance indicators, which type of performance indicators are used, and whether CO2-intensive and less CO2-intensive companies differ in this regard.

Nachhaltigkeitsziele im Sinne einer Ökologie, Ökonomie und Soziokultur lassen sich im Bauwesen auf verschiedene Instrumente zurückführen. Optimierung des Wärmeschutzes durch die Energieeinsparverordnung (Effizienz) oder Minimierung von Abfall im Kreislaufwirtschaftsgesetz (Suffizienz). Um jedoch eine neue Qualität der Nachhaltigkeit zu schaffen, ist ein Paradigmenwechsel notwendig. Dabei können Cradle to Cradle Prinzipien als ökoeffektive Methode angewandt werden, in dem exemplarisch die Biodiversität eingebunden, gesunde Bauprodukte verbaut und erneuerbare Energien genutzt werden. Die Natur dient als Vorbild (Konsistenz). Demnach werden Gebäude nützlich für Mensch, Umwelt und Gesellschaft umgesetzt und gleichzeitig Werte geschaffen. Für den deutschen Einzelhandel bestehen vielschichtige Potenziale, da der Gebäudebestand mit mehreren Millionen Quadratmetern bedeutend ist und die Bauwerke aufgrund von Konzeptänderungen oder Verschleiß der Ladenflächen regelmäßig umgebaut werden. Die Forschung beginnt mit einer Bestandsaufnahme von Cradle to Cradle Bauprodukten und Analyse eines real umgesetzten Einkaufszentrums. Um Einflussfaktoren von Stakeholdern zu identifizieren, wurden qualitative Experteninterviews mit ausgewählten Projektbeteiligten aus Bauherrn, Betreibern, Beratern, Mietparteien und Herstellern durchgeführt. Im Rahmen des Forschungsvorhabens wurde erforscht, inwieweit sich Bauprodukte aus der Gebäudeplanung in wissenschaftlicher Theorie und praktischer Bauwirtschaft umsetzen lassen, Geschäftsmodelle anwendbar sind, Trends und Innovationen im Zusammenhang stehen oder Änderungen in Politik oder Wirtschaft notwendig sind. Im Ergebnis wurden Maßnahmen für eine neue Qualität der Nachhaltigkeit bei Einzelhandelsgebäuden identifiziert. Exemplarisch wird anhand der Interviews deutlich, dass neben einem staatlichen Umweltzeichen oder einer Green Building Planungsdisziplin, insbesondere die Ökonomie in Form von Investitions- und Betriebskosten den größten Stellenwert besitzt. Es braucht einen staatlichen Regulierungsrahmen und neue Geschäftsmodelle, damit nachhaltige Bauprodukte wirtschaftlich werden und durch Stakeholder in den Prozessen der Planung, Bauausführung und dem Betrieb berücksichtigt werden.

The choice to continue working until or even beyond retirement is a function of the interplay of factors on micro, meso, and macro levels. Research within this area has grown significantly over the last years. I contribute to this line of research with the studies conducted within the scope of this cumulative habilitation thesis. More specifically, the aim of the research presented here is to add to the literature on later life work with the investigation of individual (micro level) as well as job and organizational (meso level) factors that have the potential to contribute to prolonged working lives. I was guided by the general research interest on how individual, job, and organizational factors contribute to later life work, and more specifically to retirement timing and work-related activities beyond normal retirement age. My research was directed by the following research questions: (1) What is the work activity potential of older people in Germany and what characterizes different types of later life work potential? (2) Which role do individual psychological factors such as personality, values, and beliefs play in the context of later life work? (3) How do specific job characteristics interact or align with individual psychological factors with regard to later life work? (4) What characterizes a holistic organizational approach to later life work that helps the alignment of the work environment to older workers’ (individual) needs and abilities? Following an introduction, I give an overview on the theoretical framework of my research in Chapter 2 (“Theoretical Background”). I describe the conceptualization of later life work before I go into multilevel antecedents of later life work and present key theoretical approaches to a person-environment fit perspective of later life work. In the following four chapters, I present ten studies corresponding to the ten scientific publications that constitute the basis of the cumulative habilitation thesis. In Chapter 3 (“Later Life Work: Work Activity Potential”) I present research on the extent as well as different types of later life work potential in Germany to describe the context for most of my research. With the two studies presented here (Büsch, Zohr, Brusch, Deller, Schermuly, Stamov-Roßnagel, & Wöhrmann, 2015; Mergenthaler, Wöhrmann, & Staudinger; 2015), I also intend to provide answers to the research question on the later life work potential in Germany and the characteristics of different later life work potential constellations. In Chapter 4 (“Later Life Work: Individual Psychological Factors”) the role of stable as well as malleable individual psychological factors for later life work is explored in two studies (Fasbender, Wöhrmann, Wang, & Klehe, 2019; Wöhrmann, Fasbender, & Deller, 2016). Thus, with the studies presented in this chapter, I contribute to the research question on the role of individual psychological factors in the context of later life work. In Chapter 5 (“Later Life Work: Job Characteristics Corresponding to Older Workers’ Needs and Abilities”) I present three studies exploring the interplay of individual factors and job characteristics for later life work to address the research question on the interaction or alignment of specific job characteristics with individual psychological factors with regard to later life work (Pundt, Wöhrmann, Deller, & Shultz, 2015; Wöhrmann, Brauner, & Michel, 2020; Wöhrmann, Fasbender, & Deller; 2017). Chapter 6 (“Later Life Work: A Holistic Organizational Approach”) reports the development of the Later Life Workplace Index (LLWI) as a multidimensional tool to holistically assess organizational practices and working conditions targeted at the promotion of later life work through the maintenance and enhancement of older employees’ health, work ability, and motivation (Wilckens, Wöhrmann, Adams, Deller, & Finkelstein, 2020; Wilckens, Wöhrmann, Deller, & Wang, 2020; Wöhrmann, Pundt, & Deller, 2018. With the LLWI, I intend to provide an answer to the research question on the characteristics of a holistic organizational approach to later life work that helps the alignment of the work environment to older workers’ (individual) needs and abilities. Finally, in Chapter 7 (“General Discussion”) I discuss the contributions, implications, and limitations of my research presented here.

Increased international compliance with human rights and democracy standards is a core issue for both human rights and democratizing actors as well as for victims of human rights abuse. International human rights organizations (IHROs) are expected to make positive contributions to this end, even though they possess low levels of authority. This authority has been renegotiated multiple times in various reform processes. An oversimplified expectation would have us assume that democracies would want to strengthen IHROs, and that autocracies would seek to weaken them. As the United Nations Human Rights Council (UNHRC) was reformed in 2006, 2007, 2010, and 2011, some autocracies strived to abolish parts of the UNHRC. Other autocracies aimed “merely” to weaken them. Democracies displayed an even larger variance. Indonesia and India predominantly favored weakening the UNHRC, whereas Ghana and Spain supported exclusively strengthening of the organization. Additionally, some attitudes towards the UNHRC changed from one year to the next. Autocracies diverge not only in their stances towards the UNHRC, but also across their domestic and international dimensions. Nigeria allows different levels of participation by societal actors than, say, Belarus. Cuba does not have the same domestic institutions as Russia. Iran enters international negotiations from a different position than Thailand. Democracies vary on the domestic and international dimensions as well. The Czech Republic is not the US, and Costa Rica is different from South Africa. The question that drives my research is how we can explain the broad variety of state preferences for strengthening or weakening IHROs. Previous research has mostly concentrated on democracies, leaving autocracies understudied. It also treated countries as black boxes. To account for such shortcomings, first, I systematically test the relationship between the UNHRC and its authoritarian and democratic members by means of inferential statistics. Second, I analyze a bottom-up process inherent to New Liberalism. It scrutinizes the role of domestic societal actors, domestic institutions, as well as pressures on the international stage. The results reveal that societal actors, along with the interplay of wealth and regime type in the international realm, figure as the most important predictors of delegation preferences voiced by autocracies and democracies during the reform of the monitoring bureaucracy Special Procedures of the UNHRC. Societal actors play a more important role in democracies than in autocracies. Institutionalized domestic oversight mechanisms help societal actors to conduct effective lobbying at the domestic level. Oversight mechanisms are more important than the rule of law and electoral institutions. Regarding international coalition building, authoritarian regimes turn out to be better organized than democracies. I conclude that supporters of strong IHROs shall 1. empower domestic societal actors; 2. disrupt cohesive delegation preferences of authoritarian regimes; and 3. invest in independent domestic oversight mechanisms.

Im deutschen Schulsystem wurde auf die Coronapandemie mit vielfältigen, teilweise schnelllebigen Maßnahmen reagiert. Insbesondere drei Akteursgruppen versuchten dabei Einfluss zu nehmen: Schulen, Familien und Politik. Theoretisch gerahmt von Schimanks (2010) Akteur-Struktur-Dynamiken, wird im Beitrag empirisch der Fragestellung nachgegangen, wie Schulen, Familien und Politik sich in Presseberichten positionieren bzw. positioniert werden. Auf der Grundlage dieser medialen Konstruktion erschließen wir, wie sich die Akteursgruppen selbst und wie sie die jeweils beiden anderen sehen. Untersucht wurde die deutsche Presseberichterstattung während zwei Drei-Monats-Zeiträumen im Jahr 2020. Aus einer Vielzahl verschiedenartiger bundesweiter und regionaler in der Datenbank LexisNexis verzeichneter Quellen wurden zwei Datensätze erstellt (n=178) und einer qualitativen thematischen Analyse unterzogen. Datensatz 1 wurde induktiv, Datensatz 2 deduktiv codiert. Sechs Themen wurden aus den Daten herausgearbeitet, die aus indirekter Perspektive tiefgehende Einblicke in die Selbst- und Fremdwahrnehmung jeder Akteursgruppe sowie deren Entwicklung im Zeitverlauf bieten. Wie die Analyse zeigt, gibt es von Seiten der schulischen AkteurInnen eine wachsende Digitalisierungsbereitschaft. Darüber hinaus folgt aus den als zu kurz-greifend aufgefassten politischen Maßnahmen der Gestaltungswille, den Digitalisierungsschub nachhaltig bestmöglich zu nutzen. Es lässt sich ferner ein zunehmender Zusammenhalt zwischen Schulen und Familien beobachten. Beide bringen in ansteigendem Maße Verständnis für die Situation und die Handlungen der anderen Gruppe auf. Gleichzeitig stehen Schulen und Familien der Akteursgruppe Politik zunehmend kritisch gegenüber und nehmen deren Handeln als nicht zukunftsorientiert, wenig kohärent und soziale Disparitäten vergrößernd wahr. Um Handeln und Handlungsintentionen besser verstehen, nachvollziehen und teilweise erklären zu können, werden die drei untersuchten Gruppen Schimanks vier partiellen Akteursmodellen zugeordnet. Auf Basis der Analyse werden Dynamiken in der Entwicklung von Akteurskonstellationen diskutiert.

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.

Beginning with the theology of Martin Luther and drawing on a selection of feminist theologians, this thesis proposes a relational, agential model of human flourishing. It is rooted in Luther’s doctrines of the hiddenness of God and of God’s alien and proper work in the lives of believers. Such an approach gives rise to questions concerning human freedom and agency, sin, and the nature of our relationship with God and with other persons. Many feminist theologies provide an inadequate account of sin and its effects on the person and their relationships. This thesis asserts that taking sin and its effects seriously is essential to developing a secure and healthy self, and a healthy relationship with God and other persons. It therefore proposes a reworked understanding of religious incurvature as a relational model of sin which supports the goal of human flourishing. This concept of the self curved either inwards, or towards another, speaks to the nature of sin in its traditional understanding of sin as pride, as well as addressing feminist criticisms that the notion of sin as pride is not relevant to the needs and experiences of women. The model of human flourishing proposed here is specifically Christian in its assertion that we do not exist as persons, are not fully human, without our being in relationship with the triune God and other created persons. We flourish in community. Further, it supports the idea that true Christian freedom consists of a life dedicated to service of God and others.

Corporate Social Responsibility (CSR) has been established in recent years as an essential component of the economic system, demanded and promoted by a wide variety of stakeholder groups. The present dissertation shows that organizations face major communicative challenges with regard to CSR. CSR is not only determined by organizations themselves, but rather arises in the interplay with economic and social discourses. It is assumed that boundarys of organizational action are under constant change, so that CSR actors inevitably initiate constitutive communication processes. The resulting polyphony requires an understanding of the underlying communication processes. Hence, the performative character of CSR communication is taken up by this dissertation and thus the constitution of both the communicating actors and their relationships in the network is illustrated. The presented scientific papers are united by the overarching assumption that communication does not accompany and describe organizational action, but unfolds its own power.

Der vorliegende Beitrag präsentiert ein (Simulations-) Modell zur Erklärung des Verhaltens von Organisationen. Der Modellentwurf basiert auf einem funktionalistischen Ansatz. Danach kann eine Organisation nur überleben, wenn es ihr gelingt, den Systemanforderungen, die sich auf Or-ganisationen richten, zu genügen. Veränderungen von Systemanforderungen bewirken daher An-passungsreaktionen, die allerdings nicht reibungslos ablaufen. Das Modell beschreibt den Verhal-tensprozess, der durch ein gestörtes Systemgleichgewicht ausgelöst wird. Als Modellvariable fun-gieren die Systemanforderungen und das zu seiner Bewältigung implementierte Institutionelle Ar-rangement sowie außerdem Sensitivität, Handlungsbereitschaft, Beharrung, Realismus, Identifika-tion, Handlungsdruck, Unsicherheit, Dysfunktion und Dissonanz. Die Simulationsrechnungen zei-gen, wie sich aus den jeweiligen Variablenkonstellationen bestimmte Verhaltensmuster herausbil-den und welche Mechanismen dafür verantwortlich sind.

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.

Who is taken into consideration when we talk about the citizens, about the people or the activists? Often it is a rather unquestioned privileged positionality, which is taken to be the standard that most of the time it is actually not. In this quote, the activist Madjiguène Cissé, from the transnational Sans-Papiers movement, raises that just because someone or something is not visible—to the broader public or a particular public—it does not mean that they have not been there for a long time. Migrant rights activism is not a new phenomenon but has intensified and become more networked and visible over the past years (Eggert & Giugni, 2015). This study explores group contexts of activism by, with and for refugees and migrants in Hamburg, the claims, interactions, challenges and processes that activists experience, discuss and deal with. I have approached activists experiencing political organizing in this context from a constructivist grounded theory perspective. This allowed me to develop conceptual perspectives grounded in activist groups’ realities and was advanced through existing literature on this social movement but also theories from other research fields. Solidarities emerged throughout the research process as a more concrete focus. This research sets out to answer the questions: What does solidarity mean in social movements, and how do migrant rights activist practices result in negotiating, enacting and challenging it? This publication is a revised version of my dissertation thesis.

The academic literature holds high expectations of crowdfunding to foster sustainable development by closing the funding gap for sustainable entrepreneurs. In particular, crowdfunding is considered a promising instrument for transforming existing socio-technical regimes by financing radical innovations of such entrepreneurs. However, this potential has not yet been fully explored. Large knowledge gaps exist especially in the area of investment-based crowdfunding. Therefore, this dissertation addresses the overarching research question of how sustainable entrepreneurs can exploit the full potential of investment-based crowdfunding to develop from niche operators to actors in the socio-technical regime. Five journal articles and one book chapter are included in this PhD project, which use a wide range of quantitative methodologies. In the framework paper, the findings are conceptually evaluated on a meta-level by applying the multi-level perspective. The key insights can be assigned to four categories, including the financing and marketing function, the target group, and the project presentation. The analysis shows that investment-based crowdfunding is suitable to equally fund and market the business ideas of environmental entrepreneurs, since the quest for entering the mass market is highest for such ventures. In contrast, purely social entrepreneurs tend to conduct crowdfunding projects on a smaller scale and probably aim to stay in the niche. Nevertheless, profit-oriented social entrepreneurs are still encouraged to use investment-based crowdfunding for funding and marketing purposes. The prominent display of environmental effects (e.g. the amount of compensated greenhouse gases) and financial incentives (e.g. high interest rates) has a high impact on the investment decision of individuals on investment-based crowdfunding platforms. The findings also suggest that the typical supporter of sustainability-oriented crowdfunding projects is younger than 50 years, has achieved at least a university degree and holds low levels of self-enhancement and conservative values. The case of fairafric is used as a best practice example to demonstrate how crowdfunding can be a stepping stone for sustainability-oriented niche actors to enter the mass market. The fair-trade and organic chocolate manufacturer has undergone six crowdfunding campaigns which enabled it to grow and build a strong community of supporters. The outcomes of this dissertation clarify how sustainable entrepreneurs can unleash the potential of investment-based crowdfunding for financing and marketing purposes.

In May 2020, the arrest and killing of George Floyd were followed by an uproar that reached far beyond Minneapolis (Taylor 2021). Under the “Black Lives Matter” (BLM) movement, people unitedly demonstrated against police brutality and systemic racism in the U.S. Though racially motivated police violence did not end with George Floyd. The incident contributed to a more visible reality of a judicial and societal system built upon racism. In 1989, legal scholars developed the Critical Race Theory to recognise and examine racism embedded in the legal system. However, racism is not only found in legal studies but is also ingrained in and reproduced by schools. Scholars indicate that the educational system in the U.S. is now more segregated and unequal than ever. Also, topics such as racism, Whiteness, and White-supremacy are underrepresented in schools and teacher education (Milner Ⅳ, Deans Harmon, and McGee 2022, 364). If and how a CRT perspective should be taught in schools depicts a current controversy between politics, teachers, and parents.

Neben den von Hathaway aufgeführten Folgen der industriellen Landwirtschaft, lassen sich außerdem weltweit degradierte Böden, massives Artensterben und ein zunehmender anthropogener Klimawandel verzeichnen. Infolgedessen lassen sich ebenso Auswirkungen auf die soziale Sphäre feststellen, beispielsweise negative Einflüsse auf die menschliche Gesundheit und die ungleiche globale ökonomische Gewinnverteilung. Um diesen Trend zu brechen, muss Landwirtschaft neu gedacht und transformiert werden. Dafür bedarf es innovativer und vor allem nachhaltiger Landnutzungskonzepte, die eine zukunftsfähige Lebensmittelproduktion gewährleisten. In diesem Kontext ist die Sicherstellung der nachgefragten Produktmengen ebenso relevant, wie ein ökologischer Beitrag für gesündere Böden, für die Förderung der Artenvielfalt, die Speicherung von Kohlenstoff und für ein intaktes Klimageschehen. Gleichzeitig sollte das Ziel sein, dass die Landwirt*innen gut von ihrer Arbeit leben können. Einen Beitrag zu einem solchen zukunftsfähigen Landnutzungskonzept können Waldgärten leisten. Dabei handelt es sich um mehrschichtige Systeme, welche multifunktional die natürliche Struktur von Wäldern und Waldrändern imitieren. Auf diese Weise können verschiedene Funktionen erfüllt werden, wie beispielsweise die Produktion von vielfältigen Lebensmitteln. Bisher ist das Konzept des Waldgartens in Deutschland noch nicht weit verbreitet. Es wurde bisher wenig wissenschaftliche Forschung auf dem Gebiet betrieben und in Deutschland existieren bisher nur wenige Waldgärten. In anderen Ländern bestehen hingegen schon länger erste Erfahrungen oder auch schon lange Traditionen mit Waldgärten. Im Folgenden wird die Fallstudie Hof an den Teichen vorgestellt, zusammengefasst welche Vorarbeiten bereits stattgefunden haben und das Forschungsziel und die Forschungsfragen hergeleitet.

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

Im deutschsprachigen Raum fehlt es an gezielten präventiven Maßnahmen für Kindergartenfachkräfte, um das Emotionswissen von Kindern kontextsensibel und alltagsintegriert über die Sprache in Routinesituationen zu fördern. Diese Lücke soll durch die Entwicklung und Evaluation eines Emotionswissen-Trainings („Ems“) für Kindergartenfachkräfte geschlossen werden. Im 1. Teil soll auf den theoretischen Hintergrund des Konstrukts „Emotionswissen“ eingegangen werden. Darüber hinaus wird erklärt, wie sich das Emotionswissen im Kindergartenalter entwickelt, welche Rolle die Sprache spielt, warum die Förderung wichtig ist und welche aktuellen kommunikationsbasierten Tools geeignet sind, um das Emotionswissen bei Kinder zu fördern. Der folgende Abschnitt beschäftigt sich mit den Auswirkungen fehlender Förderung des Emotionswissens sowie den Fördermöglichkeiten im Kindergarten. Dabei wird auf bereits existierende Präventions- und Interventionsprogramme eingegangen. Im Anschluss folgt die theoretische Einbettung sowie die Entwicklung und Umsetzung von Ems. Die verschiedenen Trainingsinhalte sowie die angewendeten Methoden werden vorgestellt. Dann folgen theoretische Vorüberlegungen sowie die Evaluation von Ems auf vier verschiedenen Ebenen. Abschließend werden in diesem Abschnitt Zielsetzungen und Fragestellungen der Evaluation formuliert. Im folgenden Abschnitt werden dann die verwendeten Methoden näher vorgestellt. Im Ergebnisteil erfolgt zuerst die Analyse der fehlenden Werte. Da in der vorliegenden Arbeit eine hohe Anzahl an fehlenden Werten vorlag, wurden die Daten imputiert und anschließend separat (originale und gepoolte Daten) dargestellt. Es folgt im Anschluss eine Darstellung der methoden- und erwartungsbezogenen Ergebnisse. Im letzten Abschnitt der Arbeit werden die Ergebnisse der Evaluationsstudie interpretiert und in die aktuelle Forschung eingeordnet. Darüber hinaus wird Ems mit drei anderen deutschsprachigen Präventionsprogrammen verglichen. Abschließend werden die Limitationen der Evaluationsstudie besprochen. Es wird auf Anregungen und einen Ausblick für zukünftige Studien eingegangen.
