A successful integration of migrants into the labour market and in the organisations is getting more important based on demographic changes. The central aim of the investigation is to deal with problem fields of the human resource management, which arise by demographic changes regarding migration. Therefore, an explorative qualitative study with human resource managers and diversity representatives of the large DAX companies was conducted. The views of leaders and employees with and without an immigration background regarding diversity potentials in organisation are compared in this study. The results indicate that diversity is important for organisation. Employees have recognised the importance of diversity. Managers have not recognised the seriousness and urgency of cultural diversity and diversity actions. Human resource managers are not able to assess the additional stress of migrants correctly and to consider them in their day-to-day management and diversity actions.

The transformation of an energy system is complex and requires not only technical measures, innovation and changes in lifestyle, but also increasing agricultural land use, especially for the construction of wind turbines or solar panels. Land use for biofuel cultivation is also relevant. Participants in transdisciplinary workshops use the simulation tool 100prosim to create and discuss their new energy scenario and learn about the complexity and requirements of the energy transitions regarding land use for renewable energy. The goal is to create an energy system that is supplied completely through renewable energy, while maintaining the balance between consumption and production. The focus is not on economic but on ecological factors and those related to land use. The holistic view of the tool and the visualization make it possible for participants to get an idea of the size and use of the energy production areas planned. Consequently, participants can identify possible conflicts of use, such as feed production and food security, to be discussed as a basic requirement for determining spa ce for opportunities and a desirable optimum.
Die Idee der nachhaltigen Entwicklung bietet ideale Kriterien, anstatt konkrete Lösungen anzubieten. Sie entstand als Kritik an der Sichtweise, dass Wirtschaftswachstum allein gleichbedeutend mit gesellschaftlichem Fortschritt sei, und betont die Notwendigkeit ökologischer und ethischer Überlegungen. Die Brundtland-Definition ist zwar ein Meilenstein der Nachhaltigkeitsdebatte, leidet aber daran, dass sie sich auf „Bedürfnisse“ und nicht auf die Verwirklichung von Freiheiten konzentriert, und ihr primärer Fokus auf die Gerechtigkeit zwischen den Generationen geht auf Kosten der Beachtung von intragenerationeller Gerechtigkeit. Nachhaltige Entwicklung ist ein umfassendes Gut, bei dem es nicht nur um die Vermeidung von ökologischen Schäden geht. Im Kern geht es um den Ausgleich von Interessenkonflikten zwischen den Generationen und zwischen den heute lebenden Menschen, und dies erfordert eine gleichzeitige Beachtung der teleologischen Dimension des guten Lebens und der deontologischen Dimension der Gerechtigkeit.
Biogas production is a relevant component in renewable energy systems. The paper addresses modeling approaches from an energy system, as well as from a process optimization, point of view. Model approaches of biogas production show different levels of detail. They can be classified as white, gray, and black box, or bottom-up and top-down approaches. On the one hand, biogas modeling can supply dynamic information on the anaerobic digestion process, e.g., to predict biogas yields or to optimize the anaerobic digestion process. These models are characterized by a bottom-up approach with different levels of detail: the comprehensive ADM1 (white box), simplifications and abstractions of AD models (gray box), or highly simplified process descriptions (black box). On the other hand, biogas production is included in energy system models. These models usually supply aggregated information on regional biogas potentials and greenhouse gas emissions. They are characterized by a top-down approach with a low level of detail. Most energy system models reported in literature are based on black box approaches. Considering the strengths and weaknesses of the integration of detailed and deeply investigated process models in energy system models reveals the opportunity to develop dynamic and fluctuating business models of biogas usage.
At Higher Education Institutions, student and staff mobility significantly contributes to overall CO2 emissions (Helmers, Chang and Dauwels, 2021). To design ‘regenerative landscapes’, mobility must be considered in context. The research project EN ROUTE uses real-world experiments to investigate the connection between campus design and mobility at Osnabrück University of Applied Sciences, asking: How can real-world experiments disrupt unsustainable mobility practices in landscapes of higher education? (How) Can campus design influence this? In a transdisciplinary process, the researchers co-designed real-world experiments with students at campus. The group started disrupting the status quo by engaging with the landscape, intervening in it, adding new uses, testing new practices and inspire others through spatial changes. The experiments served as a communication tool and catalyst for a transformation process, vividly demonstrating how new uses of the campus could look and how they would alter mobility practices.
Climate Change Combat and Disaster Management with re.photos, the Web Portal for Rephotography
(2022)
Comparing two or more images taken on different dates from the same vantage point is beneficial for rescuers, researchers, and politicians to improve the assessment of natural disasters and climate change. Rephotography, i.e., shooting and comparing two or more images, can show fast changes in surroundings, e.g., before and after a tsunami, earthquake, and other environmental disasters, as well as slow changes like glacial movements. Retrieving these rephotographies is difficult since images from different shooting dates are usually not found on a single source, are without georeference, are lacking in metadata like precise recording times, and have different or no licensing information. Thus, rephotography is time intensive, costly, and not easy to use by rescuers. Overcoming the drawback and providing rephotography after disasters, our web portal re.photos addresses the difficulties of automatic image registration for large scene changes as happened after, e.g., earthquakes. Once the images are registered, georeferenced, and stored in a database, our web portal provides this in an easy-to-use interface. This database of compilations can be queried via metadata search. Rephotographies of two or more images is visualized as a table or on an interactive map. We provide custom interactive registration methods to register complex compilations with only a few fixed corresponding landmarks in the before and after images. By providing these interaction methods, rephotography for disaster management become valuable, e.g., by registering images of flooded or destroyed areas within minutes. re.photos allows its users to retrieve existing compilations, create template images that colleagues or citizen scientists can rephotograph, and register, georeference and persistently publish their rephotographic compilations.
