Design methods for collaborative knowledge production in inter- and transdisciplinary research
(2022)
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.
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.
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, the author first reviews 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), he performs 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 cover the three ESG dimensions, respectively. In line with the SLR, his event studies reveal substantial stock losses to firms involved in misconduct that are eventually even accompanied by a spillover effect to uninvolved bystanders. Then, the author reviews 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, he assesses 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, he introduces 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, the author outlines 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.
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 untersucht, 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.
Mit der vorliegenden Arbeit werden die bis Ende 2020 entstandenen gesetzlichen Strukturen und Instrumente zum Ausbau erneuerbarer Energien aus rechtswissenschaftlicher Perspektive eingeordnet, um der Frage nachzugehen, mit welchen Ansätzen und in welchem Umfang der Rechtsrahmen die verschiedenen Entwicklungen zur Erreichung der Ausbauziele für die erneuerbaren Energien einerseits und damit deren Beitrag zur Erreichung der Klimaschutzziele steuern kann. Darüber hinaus wird beleuchtet, welche Reformperspektiven aus den bisherigen Entwicklungen abgeleitet werden können oder sollten. Dazu werden die Strukturen und Elemente des Erneuerbare-Energien-Rechts sowie dessen Entwicklungslinien herausgearbeitet und bewertet. Dieser Schritt erfolgt durch die Analyse einzelner, für das Recht der erneuerbaren Energien prägender Strukturen und Entwicklungsschritte, etwa der Schaffung neuer Instrumente wie der Nutzungspflicht erneuerbarer Energien, der Beschreibung der prägenden Strukturelemente und Wirkungszusammenhänge in dem sich im Laufe von 30 Jahren herausgebildeten Recht der Erneuerbaren Energien im Stromsektor oder anhand der Einordnung von tiefgreifenden gesetzgeberischen Veränderungen wie der Umstellung auf Ausschreibungen im Erneuerbare-Energien-Gesetz. Diese Einzelbeobachtungen werden dann in Beziehung zueinander gesetzt, Gemeinsamkeiten und Unterschiede der hinter den Entwicklungen erkennbaren Gründe herausgearbeitet und in einen übergeordneten Gesamtkontext. Die Arbeit gliedert sich in vier Schritte, die sich einer kurzen einleitenden Problemskizze in Teil 1 anschließen: die grundlegende Analyse zu Recht und Klimaschutz sowie zur Rolle des Rechts bei der Transformation (Teil 2), eine umfassende Bestandsaufnahme zu den Bausteinen des Erneuerbare-Energien-Rechts, den Entwicklungslinien und deren Einordnung (Teil 3), ein Zwischenfazit, das die Gründe für die beobachteten Entwicklungslinien und Strukturen zusammenfasst und eine Einordnung des Rechts der erneuerbaren Energien in den größeren Kontext des Umweltenergierechts (Teil 4) sowie abschließend ein auf einer Einordnung des Rechts der erneuerbaren Energien in den Kontext der neu entstehenden Klimaschutzgovernance beruhenden Ausblick auf mögliche Themenfelder der weiteren Rechtsfortbildung (Teil 5).
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 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 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 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.
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.
Understanding that entrepreneurship can be better modeled from a systemic point of view is a primordial aspect that determines the important role of universities in entrepreneurial ecosystems. What makes the ecosystem approach a valuable tool for understanding social systems is that, from a holistic perspective, their behavior seems to have emerging characteristics. This dissertation presents a dual scientific account of the entrepreneurship phenomenon in universities. The work is divided into two equal parts, each of which is composed of two research papers. The narrative of the first half takes on a macro perspective view, consisting of one theoretical and one empirically-based conceptual case study. This part conceptually depicts a systematic approach to entrepreneurialism in higher education, namely an ecosystems perspective. The second half concentrates on the meso- and micro levels of study from the university's point of view, comprising of a case study as historical account for the emergence of the entrepreneurial university, and of a metasynthesis of empirical case studies in entrepreneurial universities, which serves as the basis for the development of entrepreneurial university archetypes. This doctoral work contributes to an in-depth understanding of Entrepreneurship in universities regarding its systemic qualities and archetypal characteristics of entrepreneurial universities. It argues for an ecosystem's perspective on the phenomenon of entrepreneurial activity, highlighting the fundamental role that universities play as the heart of entrepreneurial ecosystems. Furthermore, this research expands on the novel concept of the entrepreneurial university by using extensive case study literature to empirically identify distinct archetypes that better reflect the diverse reality of how universities engage as entrepreneurial actors by way of differentiated entrepreneurial structures, systems, and strategies.
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.
Die Wahl der Rechtsform stellt im Zuge der Neugründung eines Startup-Unternehmens für die Gründer eine wichtige Entscheidung dar, denn sie beeinflusst unmittelbar den Gründungsprozess sowie im Nachhinein den Geschäftsbetrieb der gegründeten Gesellschaft. Besonders interessant ist eine Rechtsform mit Haftungsbeschränkung, welche die beliebte GmbH als Kapitalgesellschaft ermöglicht und damit eine persönliche Haftung der Gründungsgesellschafter verhindert. Problematisch ist jedoch für Gründungsinteressierte, die zu Anfang über nicht genügend Startkapital verfügen, die hohe Summe des geforderten Mindeststammkapitals der GmbH aufzubringen. Hier könnte die UG (haftungsbeschränkt) als Option infrage kommen, da sie eine Haftungsbeschränkung ermöglicht und dabei kein gesetzlich festgelegtes Mindeststammkapital bei der Gründung fordert (§ 5a Abs. 1 GmbHG). Die vorliegende Arbeit behandelt die Frage, weshalb sich die UG (haftungsbeschränkt) gerade für die Gründung eines Startup-Unternehmens als optimale Einstiegsrechtsform eignet. Das Ziel der Arbeit ist, die UG (haftungsbeschränkt) in ihrer Besonderheit mit den speziellen Sondervorschriften, die in § 5a GmbHG verankert sind, darzustellen. Zudem soll die Verbundenheit zur GmbH aufgezeigt werden. Die Arbeit dient dabei auch als Leitfaden für die Neugründung eines Startup-Unternehmens in Form der UG haftungsbeschränkt) und zeigt, wie die Gründung auf einfachster Weise unter geringen Kosten mit dem Start einer UG (haftungsbeschränkt) gelingen kann.
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.
Companies increasingly use social and environmental accounting and reporting (SEAR) to measure, manage, and report their influence on ecological and social issues, i.e., climate change and human rights violations. Nowadays, there are many different tools, frameworks, and standards for SEAR that companies can use. Beyond the content presented in the tool itself, e.g., social and/or ecological information, these tools differ, among others, by the language used and the type of data collected (e.g., qualitative, quantitative, or monetary data). This dissertation aims to expand previous literature by clarifying the effects of SEAR on corporate decision-making and its influencing factors. Additionally, antecedents for implementation and use of SEAR in regard to supporting sustainability decision-making are discussed. For this purpose, the given dissertation investigates public sustainability reports by companies with different environmental orientation, conducts two survey-based case studies on the effects of different types of SEAR and one qualitative case study on the antecedents of institutionalizing management accounting change through SEAR. The results lead to seven criteria that practitioners and researchers should recognize for supporting successful SEAR regarding a company's environmental orientation, the role of employees and leadership as well as the specific SEAR tool itself.
The global coffee market is connected to many sustainability issues like the persisting poverty of coffee farmers, and degrading ecosystems. Many interventions, from state-led regulation to industry-led certification processes, exist, that try to change global value chains to shift societies back on more sustainable trajectories. To this date, it is still under debate if these interventions are an effective means to change global value chains. With climate change and persisting issues of social justice as strong accelerators, calls are increasingly made for a radical transformation of global production and consumption patterns. Many frameworks try to inform research and real-world policies for a transformation of global value chains. In this dissertation, the author uses the framework of the practical, political and personal sphere proposed by O'Brien and Sygna (2013) highlighting that the interactions between these three spheres bare the greatest potential for a transformation towards sustainability. However, in this dissertation, the author argues that it is exactly at the nexus between the three spheres of transformation where barriers towards a fundamental shift of systems occur. He, therefore, uses three perspectives to bring empirical nuance to the problems that arise on the interplay between the different spheres of transformation. (1) The scientific perspective: using a systematic review of alternative trade arrangements; (2) the producer perspective: facilitating a participatory network analysis of social-ecological challenges of Ugandan coffee farmers and their adaptive management practices; (3) the consumer perspective: through the use of a German consumer survey and a structural equation model to investigate into the Knowledge-Doing-Gap end-consumers are facing. Through the results from the scientific perspective, the author is able to show that most of the research is investigating the certified market and that the effectiveness of labels rarely exceeding the practical sphere. His empirical research on the producer perspective highlights that Ugandan coffee farmers facilitate a variety of on-farm crop management (practical sphere) but their support structures rarely exceed informal exchange with neighboring communities (political sphere). Exchange with governmental actors and global traders is happening but has been assessed as not sufficient to cope with the social-ecological challenges the producers are facing. Through the results of the consumer perspective, the author is able to highlight that even though end-consumers have pro-sustainable attitudes (personal sphere) they are facing situational constraints (political sphere) that create a gap between their attitudes and the respective behavior. Using these empirical insights about drivers and barriers for a transformation he proposes that frameworks, aiming to inform research and policies, need to include two aspects: (1) the notion of a forced transformation; and (2) the translational capacity of the frameworks to create meaningful interdisciplinary discourses in different contexts. The author, therefore, propose two approaches:(1) a fourth sphere, called the "planetary force" to include the notion of a forced transformation that is already happening in different contexts, highlighted by the producer perspective in this dissertation; and (2) the consequent use of methods that create interdisciplinary exchange and rigorous testing.
Die empirische Unterrichtsforschung verfolgt das Ziel, Unterricht und die darin stattfindenden Prozesse zu beschreiben und zu beurteilen und deren Einfluss auf den Lernerfolg von Schülern zu analysieren. Auch wenn Videostudien zu den aufwändigeren Verfahren in der empirischen Unterrichtsforschung zählen, werden sie vermehrt eingesetzt, um sich diesen Unterrichtsprozessen anzunähern. Mittels Videografie werden Verhaltensweisen und Prozesse sicht- und messbar, die den Lernerfolg von Schüler maßgeblich beeinflussen können. Die detaillierte, reliable und valide Erfassung von Unterrichtsprozessen ist jedoch an Bedingungen geknüpft, die spezifische Herausforderungen für Videostudien darstellen und im Rahmen dieser Dissertation in drei Teilstudien empirisch untersucht werden. Allen Teilstudien liegen Unterrichtsvideos zugrunde, die mittels eines schülerzentrierten Aufnahmesystems aufgenommen wurden. Bei einem schülerzentrierten Aufnahmesystem werden ergänzend zu der Lehrkraftkamera und der Überblickskamera an jedem Gruppentisch weitere Kameras aufgestellt, um die Handlungen und Interaktionen aller am Unterricht beteiligten Personen im Detail erfassen zu können. In Teilstudie 1 wird ein potenzieller Reaktivitätseffekt bei Schülern als eine zentrale Herausforderung von Videostudien untersucht, der zu Verzerrungen des Datenmaterials aufgrund der Anwesenheit von Kamera(personen) führen kann. Dadurch kann die Validität der Daten einschränkt werden. In Teilstudie 2 wird der Herausforderung des in Videostudien oftmals geringen Beobachtungszeitraums begegnet, indem untersucht wird, wie stabil das verhaltensbezogene Engagement von Schülern im Verlauf einer videografierten Unterrichtsstunde ist bzw. wie lange Schüler in ihrem verhaltensbezogenen Engagement beobachtet werden müssen, um dieses zuverlässig erfassen zu können. In Teilstudie 3 wird der methodische Ansatz der Netzwerkanalyse vorgestellt, durch welchen der Herausforderung bezüglich der Beschreibung und Bewertung komplexer Wirkgefüge im Unterricht begegnet werden kann. Mittels einer Netzwerkanalyse können dynamischen Interaktionsprozesse im Unterricht detailliert und im zeitlichen Verlauf des Unterrichts beschrieben werden. Insgesamt werden im Rahmen dieser kumulativen Dissertation zentrale Herausforderungen der videobasierten Unterrichtsforschung betrachtet und Lösungsansätze zu deren Überwindung vorgeschlagen. Nur wenn diese Herausforderungen berücksichtigt werden bzw. ihnen begegnet wird, kann die empirische Unterrichtsforschung fruchtbare Erkenntnisse liefern, die zum Verstehen von Unterricht beitragen und schlussendlich zu einer Verbesserung der Unterrichtspraxis führen können.
