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.
Algorithmic distribution has fundamentally altered the news industry and has led to conflicts over regulatory issues. Focusing on the introduction of European ancillary copyright, this chapter addresses an earlier international reform around algorithmic news distribution. Based on an in-depth thematic analysis of key documents from the policy formulation phase, the chapter maps the arguments for and against the ancillary copyright reform put forward by Google and news publishers in Germany. While we provide a detailed analysis of the underlying rationales of two key actors primarily affected by the regulation, we also place ancillary copyright in the context of competing private property and public policy visions, which allows for a better understanding of how and why different actors take particular positions on copyright reform and algorithmic regulation.
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.
This thesis aims to develop a FE-based model of a dieless wire drawing process for wires made from magnesium alloys. To this end a general material model of pure magnesium and a model of the dieless wire drawing process are developed. Based on the general pure magnesium model an alloy specific model for AZ31 wire is developed. The performance of both models is assessed using experimental data generated on a dieless wire drawing prototype.
The process model is conceptionally split into the thermal and mechanical response of the wire. The thermal model is validated by axial temperature profiles and the mechanical model is vali-dated by CSA-reduction and wire force. Both behaviours are validated separately before combin-ing the thus created models into a thermomechanical model of the dieless wire drawing process. The thermal material model is developed for pure magnesium. An initial assumption of limited correlation between content of alloying elements and thermal behaviour, was disproven. As a results in addition to alloy-specific mechanical data, thermo-electric data is recorded to achieve thermal validity of the model. This is done by identifying the experimental maximum temperature of the drawn wire for a given heating power and calculating the necessary input power of the in-duction heating device to achieve this temperature in simulation. The mechanic material model is based on experimental stress-strain curves recorded for each investigated wire materials in addi-tion to pure magnesium data, based on literature.
Results show the thermomechanical magnesium models to be mostly valid, provided process parameters stay within the range of available data on the mechanic material performance. Where the model is forced to extrapolate material behaviour, simulation quality drops. This ap-plies for wire temperature and CSA-reduction. Estimations of wire force are shown to be invalid. For AZ31 wire the thermal model generated valid temperature profiles of the wire. The thermo-mechanical model for AZ31 is shown invalid as both CSA-reduction and wire force deviate from experimental results.
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.
Der vorliegende Beitrag liefert eine deskriptive Analyse von wichtigen Einflussgrößen auf die Zu-friedenheit. Betrachtet werden drei bedeutsame Arbeitsbedingungen und vier auf die Lebensbe-wältigung bezogene Einstellungen. Als Ausgangshypothese dient die Vermutung, dass die Korrela-tionen zwischen den Arbeitsbedingungen und der Arbeitszufriedenheit enger sind als die Korrela-tionen zwischen den Arbeitsbedingungen und der Lebenszufriedenheit. Umgekehrt ist zu vermu-ten, dass die Einstellungen einer Person sich enger mit ihrer Lebenszufriedenheit als mit der Ar-beitszufriedenheit verbinden. Als Datenbasis dient das Sozioökonomische Panel.
Die Nutzung von YouTube-Tutorials in Lernprozessen wird häufig informellen Lernstilen zugeordnet. Betrachtet man die kommunikative Funktionsweise von Tutorials, können diese durch ihren instruktionalen Charakter jedoch auch als non-formales Lernangebot interpretiert werden. Strukturierung, Umfang und Thema werden durch die Videourheber bestimmt, ohne dass eine Anpassung an situative Bedürfnisse der Lernenden vorgesehen ist. Je nach Urheber kann ein Tutorial sogar einen formalen Kontext darstellen. In dieser Arbeit werden Fallbeispiele für beide Lernangebote herangezogen. Die Probanden, professionelle Musiker, sind dabei konfrontiert und treten in Interaktion mit einem postdigitalen "MusikmachDing" (Ismaiel-Wendt, 2016) auf der einen Seite und dem Computer, welcher die Plattform YouTube, Tutorials und gegebenenfalls Musik-Softwares abbildet, auf der anderen Seite. Das betrachtete Datenmaterial besteht aus filmischen Selbstdokumentationen (Maleyka et al., 2018). Anhand dieser Fallbeispiele wird innerhalb dieser Arbeit analysiert, inwiefern die Lernenden in die in den Tutorials angelegte Vorstrukturierung des Lernprozesses eingreifen. Idealerweise können so Hinweise gewonnen werden auf (1) Qualitätskriterien für die Gestaltung von digitalen Lernumgebungen und Musik-Tutorials sowie (2) auf speziell durch postdigitale "MusikmachDinge" erzeugte Herausforderungen. (3) Zudem werden die herausgearbeiteten Praktiken mit dem aktuellen Forschungsstand zu informellem und digitalem Lernen verknüpft und dadurch beispielhaft die spezifische Gestaltung postdigitaler Lernprozesse dargestellt.
