Tipps zum Umgang mit Starkregen. #Kurvekriegen - Der Klimaschutz-Podcast. 2. Staffel - Episode 3
(2021)
The first oscillating water column was invented in 1940. In the past decades the need of wave energy systems has significantly increased. This article quickly describes the Wells turbine and possibilities to enhance its performance and should answer the question: what are the design parameters that can be optimized?
Furthermore it gives a small outlook about the history of oscillating Water Columns.
A data sender in an IP based network is only capable to efficiently use a network path if it knows the packet size limit of the path, i.e., the Path Maximum Transmission Unit (PMTU). The IETF recently specified a PMTU discovery framework for transport protocols like QUIC. This paper complements this specification by presenting a search algorithm. In addition, it defines several metrics and shows results of analyses for the algorithm with various PMTU candidate sequences using these metrics. We integrated the PMTU discovery with our algorithm into a QUIC simulation model. This paper describes the integration and presents measurements obtained by simulations.
The risk sensitivity of Basel risk weights and loan loss provisions: evidence from European banks
(2021)
Despite widespread recognition of the need to transition toward more sustainable production and consumption and numerous initiatives to that end, global resource extraction and corresponding socio-ecological degradation continue to grow. Understanding the causes of this persistent failure is a necessary step towards more effective action. This article contributes to that understanding by synthesizing theory and evidence that links unsustainable production-consumption systems to power and inequality. While sustainable consumption and production research and action mostly focuses on technological or behavioral change, the socio-ecological inequalities driving production-consumption systems built into the organization of our global political economy, remain largely overlooked. In response, we propose a structural political economy orientation that seeks explicitly to reduce these inequalities and advance environmental justice and, thus, create the conditions for sustainable production-consumption systems. We then propose three important arenas of research and action towards sustainable production-consumption systems: justice, governance, and co-production of knowledge and action. These arenas, collectively and individually, can serve as entry points to study and act on the dynamics of (un)sustainable production-consumption systems. This can be done at the micro level, with respect to specific commodity chains or systems of provisioning, or at meso and macro levels with respect to national and global production networks. Our proposed orientation helps distinguish research and practice proposals into those emphasizing management and compensation resulting often in persistence of unsustainability, from those proffering structural changes in unsustainable production-consumption systems. We invite critique and collaboration to develop this research and action agenda further.
The Internationalisation of Higher Education - Perspectives from the THEA Ukraine Project and Beyond
(2021)
The Ukrainian higher education system has undergone a number
of developments since Ukraine committed itself to the Bologna
Process in 2005. Internationalisation and quality assurance in higher
education have thus become two core policy issues to aid Ukraine’s
efforts in becoming a full member of the European Higher
Education Area.
Within the THEA Ukraine project (October 2019 – September 2021),
32 Ukrainian Higher Education Administrators received training
in the field of internationalisation in higher education and science
management. The participants worked on individual application
projects to foster the international orientation of their home
institutions, which are located all over Ukraine.
The implementation of this project has provided material for a
number of case study descriptions of projects undertaken in the
THEA Ukraine framework, as well as general perspectives on
internationalisation in higher education; this anthology covers
both of these aspects.
Common boundaries between the physical reality and rising digital media technologies are fading. The age of hyper-reality becomes an age of hyper-aesthetics. Immersive media as well as image technologies – like virtual reality – enable a completely novel form of interaction and corporeal relation to and with the virtual image structures. Virtual Images contributes to the wide range of the hyper-aesthetic image discourse to connect the concept of dynamic virtual images with the approaches in modern media theory, philosophy, perceptual theory, aesthetics, computer graphics, art history and techno-art as well as the complex range of image science. Shared goal is a critical discussion of the specific epistemology of aesthetic and scientific approaches to VR.
This volume discusses the relation of images and technological evolution in the context of virtual reality within the perspective of an autonomous image science.
The laser nitriding was performed in nitrogen gas at room temperature (20 °C) and low temperature (−190 °C) by a low power fiber laser to modify the wear and abrasion resistance of NiTi alloy. The surface roughness and element composition were analyzed by roughness device and energy-dispersive X-ray spectroscopy respectively. The results of roughness show that laser treatment can change the surface roughness due to the laser remelting. The effect of laser nitriding on the microhardness, friction coefficient, and worn scars of NiTi alloy was also studied, which shows that the microhardness of the NiTi alloy increases after laser nitriding. The optical microscope and scanning electron microscope were used to characterize the surface of NiTi alloy after wear testing to observe the microstructure of worn scars. The results show that the laser nitriding with different parameters can induce a nitride layer with different thicknesses and the higher energy deposition is the key factor for the formation of the nitride layer, which can decrease the friction coefficient and reduce wear loss during the application of NiTi alloy. The improvement of wear resistance can be attributed to the hard nitriding layer.

A synthesis is made of 10 topics within climate research, where there have been significant advances since January 2020. The insights are based on input from an international open call with broad disciplinary scope. Findings include: (1) the options to still keep global warming below 1.5 °C; (2) the impact of non-CO2 factors in global warming; (3) a new dimension of fire extremes forced by climate change; (4) the increasing pressure on interconnected climate tipping elements; (5) the dimensions of climate justice; (6) political challenges impeding the effectiveness of carbon pricing; (7) demand-side solutions as vehicles of climate mitigation; (8) the potentials and caveats of nature-based solutions; (9) how building resilience of marine ecosystems is possible; and (10) that the costs of climate change mitigation policies can be more than justified by the benefits to the health of humans and nature.
Diese Arbeit befasst sich mit Kostentrends in Zusammenhang mit technologischem Lernen von Windenergie an Land in den USA, in Deutschland und weltweit. Ziel dieser Arbeit ist es, eine Lernkurve für Windenergie an Land zu bestimmen. Dafür wurden Daten zu Stromgestehungskosten (LCOE) und Kosten für die Installation (COP) von Windenergieanlagen (WEA) im Zeitraum von 1983 bis einschließlich 2020 gesammelt, grafisch dargestellt und weitergehend ausgewertet. Die grafische Darstellung der Datenlage verdeutlicht die zeitliche Entwicklung der Technologie. Zur Beschreibung dieser Lernkurven wurden die Progress Ratio (PR) und Learning Rate (LR) in fünf unterschiedlichen Modellen bestimmt. Anhand derer sich in Kombination mit der zukünftig installierten Leistung von WEA eine Prognose über zukünftige Kosten ableiten lässt. Die ermittelten LR bewegen sich zwischen 13 % und 28 %, woraus sich LCOE im Jahr 2030 zwischen 44,03 US$/MWh und 61 US$/MWh ergeben.
Floating offshore wind (FOW) holds the key to 80 % of the total offshore wind resources, located in waters of 60 m and deeper in European seas, where traditional bottom-fixed offshore wind (BFOW) is not economically attractive.
Many problems affecting floating offshore wind turbines (FOWT) were quickly overcome based on previous experience with floating oil rigs and bottom-fixed offshore wind. However, this technology is still young and there are still many challenges to overcome.
This paper shows that electrical failures are amongst the most significant errors of FOWT. The most common cause was corrosion. It is also stated that the control system is most often affected, and that the Generator is frequently involved. Material corrosion is also the key factor when it comes to the most common overall reason for failures.
A particular attention must be paid to mooring line fracture. Mooring lines are especially vulnerable to extreme sea conditions and the resulting fatigue, corrosion, impact damage, and further risks.
It must be stated that the primary challenge is that of economics. Over time technological costs will decline making FOW more competitive and hence attractive for greater depth.
Tactical planning measures for sustainable and efficient international transportation networks

Rigorous process models provide a reliable basis for model-based monitoring and control of anaerobic digestion plants. Due to the complex model structure and non-linear system characteristics, the established Anaerobic Digestion Model No. 1 (ADM1) is rarely applied in industrial plant operation. The present investigation proposes a systematic procedure for successive model simplification and presents the description of five model variants of a mass-based ADM1. Individual model structures greatly differ in their number of implemented process phases, characteristic components and required parameters. Simplified model variants combine nutrient degradation and biogas formation based on first-order sum reactions, whereas complex model structures describe individual degradation pathways and intermediates during acido- and acetogenesis. Characteristic features of the derived model structures as well as the stoichiometric methane potentials and microbial biomass yields of the underlying degradation pathways of individual model variations are evaluated and discussed in detail.
Due to a limited number of available measurements on agricultural biogas plants, established process models, such as the Anaerobic Digestion Model No. 1 (ADM1), are rarely applied in practise. To provide a reliable basis for model-based monitoring and control, different model simplifications of the ADM1 were implemented for process simulation of semi-continuous anaerobic digestion experiments using agricultural substrates (maize silage, sugar beet silage, rye grain and cattle manure) and industrial residues (grain stillage). Individual model structures enable a close depiction of biogas production rates and characteristic intermediates (ammonium nitrogen, propionic and acetic acid) with equal accuracy as the original ADM1. The impact of different objective functions and standard parameter values on parameter estimates of first-order hydrolysis constants and microbial growth rates were evaluated. Due to the small number of required model parameters and suitable system characteristics, simplified model structures show clear advantages for practical application on agricultural biogas plants.
The impact of hydro-power plants on the ecosystem was studied with focus on the fish mortality and types of damage for many years. The fish mortality have a wide range of causes. Types of damage can be different and are caused by different parts of the power plant. The most dangerous part of the system are the fast moving turbine blades. They can cause blade strike and barotrauma due to the high speeds. Different types of turbines were developed for a better survival rate. Five different types of different research groups and manufacturers are presented in this paper. By considering those newly developed turbine designs, a fish survival rate from 96 % to 100 % is achieved.
In order to anchor the guiding idea of sustainable development in vocational education and training structurally corresponding competences must be identified and
taught within the framework of vocational education and training (VET).
This presentation presents the idea behind VET and a model for describing sustainability-related competences in food processing professions.
Innovative business models for data-driven B2B platforms evolve rapidly based on the prospects of digital technology. In addition to the platform provider, service providers on the supply side of the digital platform - the so-called complementors - play an important role in the process of value creation. This paper highlights the complementors’ perspective on the different facets of complementor relationship management (CoRM) and answers the following research questions: From the perspective of a complementor, what are the main fields of CoRM for data-driven B2B platforms? What factors of influence comprise the reason complementors join a platform?
Sexuelle Orientierungen stellen seit mindestens 20 Jahren Tatmotive für diskriminierende Hasskriminalität mit seit fünf Jahren steigenden Fallzahlen in Deutschland dar (vgl. BMI Bund 2021, S. 9). Ähnliche Befunde können somit auch für Nordrhein-Westfalen (NRW) angenommen werden. Sozialer Arbeit wird der Titel Menschenrechtsprofession zuteil (vgl. DBSH e.V. 2009, S. 14). „Wir diskriminieren nicht, wir studieren doch Soziale Arbeit“ (Beck 2015, S. 27) lautet der Titel eines Buchbeitrags, in dem sich mit diesem Anspruch eingehend beschäftigt wird. Derselbe Anspruch liest sich für studierte Fachkräfte auch aus den Arbeitsgrundlagen des Deutschen Berufsverbandes für Soziale Arbeit e.V. heraus, wonach für diese eine Pflicht gegenüber der Gesellschaft und den Nutzer:innen Sozialer Arbeit postuliert wird, Diskriminierung u.a. aufgrund von sexuellen Orientierungen entgegenzutreten (vgl. DBSH e.V. 2009, S. 8). Gegenüber Fachkräften der Sozialen Arbeit als Mitglieder der Gesellschaft gilt diese Pflicht folglich ebenfalls. Diese Befunde zusammengenommen lassen die Frage aufkommen, inwiefern die Soziale Arbeit ihren eigenen Ansprüchen gerecht wird und einen diskriminierungsarmen Raum in ihren Einrichtungen in NRW schafft oder als Teil der Gesellschaft ein Abbild dieser darstellt. Dann würden Fachkräfte der Menschenrechtsprofession andere Fachkräfte derselben Profession aufgrund ihrer sexuellen Orientierungen diskriminieren.
Stigmatisierungserfahrungen bisexueller Menschen in Mehrheitsgesellschaft und Queer-Community
(2021)
Die sexuelle Orientierung eines Menschen stellt einen wichtigen Bestandteil der eigenen Identität dar. Was aber, wenn diese in der Gesellschaft nicht wahrgenommen oder gar in ihrer Existenz geleugnet wird? Trotz einer in den vergangenen Jahren erfolgten größeren Anerkennung wird Bisexualität als eigenständige Orientierung und Identität immer noch kaum ernst genommen, oder sogar ganz infrage gestellt (vgl. Ritter, Voß 2019, S. 7). Während bisexuelle Menschen in der Alltagswelt und in Community-Debatten praktisch unsichtbar sind, werden sie gleichzeitig im Falle einer selbstbewussten Eigenbezeichnung häufig abgewertet und diskriminiert (vgl. Baranowski, Küppers 2019, S. 5). Auch im wissenschaftlichen Diskurs wird die Bisexualität selten als eigenständige Identitätskategorie untersucht. Gerade im deutschsprachigen Raum sind in den letzten 20 Jahren kaum empirische Arbeiten zu dieser Thematik veröffentlicht worden, obwohl bisexuelle Menschen wiederholt von Stigmatisierungserfahrungen berichten. An dieser Stelle soll die vorliegende Arbeit anknüpfen und die Erfahrungen bisexueller Menschen in ihrer Biografie untersuchen.

Specifying roles in purchasing and supply management in the era of Industry 4.0: A Delphi study
(2021)
New technologies and systems within the field of purchasing and supply management (PSM) call forth responsibilities and require expertise. Moving towards Industry 4.0 in purchasing, increasing attention on specialization within talent and skills, where human capital is needed to exploit the full potential of technologies. Based on an internet-based real-time Delhi study with 47 experts within the PSM field, six future purchasing roles have been defined and elaborated. These future roles connect to the maturing and emerging technologies within the purchasing field and provide a guideline to further develop towards Industry 4.0 in purchasing based on a human-centered evolutionary approach.
This paper presents the results of the technology development project “Enabling Technologies for Piezo-Based Deformable Mirrors in Active Optics Correction Chains” conducted by OHB System AG together with its partner Münster University of Applied Sciences (MUAS). The project was funded by ESA within their General Support Technology Programme
(GSTP).
We address in this paper mainly the definition, flow-down and verification of the requirements for the Deformable Mirror (DM). The requirements were derived from a set of real space mission applications. The deformation of the mirror is performed by piezo-ceramic actuators in an unimorph configuration. The finally developed DM is able produce Zernike modes with a stroke of several tens of µm over a clear optical aperture of 50 mm in diameter. It underwent successfully a full environmental qualification campaign including thermal cycling, shock- and vibration testing, as well as exposure to
proton and γ–ray radiation. Thermal and performance tests were performed in the temperature range from 100 K to 300 K.
Furthermore, the DM sustained all vibration (random 17.8 g RMS and sinus) and shock (300 g) testing. Thereby all criticalities which were identified a previous study have been overcome successfully.
A Technology Readiness Level (TRL) of 5 is reached, as the component has been validated in relevant environment. Based on the high level of maturity, this deformable mirror is now ready for the incorporation in future flight instruments. The achieved TRL of 5 is sufficient for the status of a PDR at payload level and gives thus a very good basis for all kinds of potential B2, C/D payload developments.
Die vorliegende Masterarbeit im Studiengang „Soziale Arbeit und Forschung“ behandelt die Auswirkungen des menschengemachten Klimawandels auf die Theorien Sozialer Arbeit. Um die leitende Fragestellung Wie wirkt sich der Klimawandel auf den Theoriediskurs Sozialer Arbeit aus? zu beantworten, wurden folgende Teilaspekte untersucht:
• Womit müssen sich Theorien Sozialer Arbeit befassen, um klimaspezifische soziale Phänomene zu erkennen und zu bearbeiten?
• Wie gehen aktuelle Theorien mit Aspekten des Klimawandels um?
• Wo befinden sich in den aktuellen Theorien Stärken oder Schwächen im Umgang mit dem Klimawandel? Wo sind die Theorien ggf. lückenhaft?
• Welche Schlussfolgerungen lassen sich aus den Erkenntnissen für die zukünftige Theoriebildung ableiten?
Anhand aktueller Literatur wurden zunächst Kriterien entwickelt, die einer Theorie Sozialer Arbeit Erklärungswissen zur Definition und Bearbeitung des Klimawandels als soziales Phänomen liefern. Entlang der Kriterien wurden anschließend fünf aktuelle Theorien
Sozialer Arbeit analysiert. Die Ergebnisse der hermeneutischen Theorieanalyse machen deutlich, wie unterschiedlich aktuelle Theorien Sozialer Arbeit mit der sozialen Dimension des Klimawandels umgehen. Die identifizierten Stärken, Schwächen und Lücken innerhalb der Theorien liefern Erkenntnisse für die sozialarbeiterisch-theoretische Auseinandersetzung mit dem Klimawandel. Die Ergebnisse der Arbeit können eine erste Orientierungsgrundlage für die theoretische Auseinandersetzung mit dem Klimawandel sein, zur Grundlage zukünftiger klimaspezifischer Theorierevisionen werden oder inhaltliche Impulse für die Entwicklung zukünftiger Theorieansätze geben.
Vielen Sozialarbeitenden, die im Bereich Flucht und Asyl tätig sind, dürften solche Pflichtenkonflikte bekannt sein. Die mangelhafte Umsetzung von und Ignoranz gegenüber Menschenrechten im nationalen Recht, kann dieses Differenzempfinden erklären (vgl. Prasad 2018a, S. 23).
Die vorliegende Arbeit untersucht die Rolle der Sozialen Arbeit als Zeugin von Menschenrechtsverletzungen unter besonderer Betrachtung der Umsetzung des Rechts auf Bildung von geflüchteten Kindern in Landesunterbringungseinrichtungen. Sie berührt die Frage, welcher theoretische Zusammenhang zwischen Menschenrechten und der Sozialen Arbeit besteht. Darüber hinaus wird untersucht, wie das Recht auf Bildung geflüchteter Kinder in der Landesunterbringung im Gesetz und in der Praxis umgesetzt wird und welche praktischen Handlungsmöglichkeiten der Sozialen Arbeit im Einsatz gegen Menschenrechtsverletzungen offenstehen.
„Wäre Bewegung ein Medikament, dann wäre es aufgrund seiner vielfältigen und umfassenden Wirkungen so teuer, dass kein Mensch es bezahlen könnte.“ (Sächsisches Staatsministerium für Soziales 2008, S. 4) Bewegung ist in der menschlichen Natur angelegt und gilt daher als ein natürliches und essentielles Grundbedürfnis des Menschen (vgl. Zimmer 2020, S. 19ff.). Speziell Kinder benötigen Bewegung, um sich gesund und ganzheitlich entwickeln zu können. Die Pädagogin Renate Zimmer fasst diese Aussage zusammen, indem sie Bewegung als den „Motor der Entwicklung“ (Zimmer 2020, S. 46) betitelt. Schaukeln, Klettern, Rennen, Springen und Balancieren gehören mithin zu den alltäglichen Bewegungserfahrungen von Kindern. Aufgrund ihres hoch ausgebildeten Bewegungsdrangs sind Kinder ständig auf der Suche nach neuen, spannenden Bewegungsanlässen.
Background. Ketone bodies are a highly relevant topic in nutrition and medicine. -e influence of medium-chain triglycerides (MCT) on ketogenesis is well known and has been successfully used in ketogenic diets for many years. Nevertheless, the effects of MCTs and coconut oil on the production of ketone bodies have only partially been investigated. Furthermore, the increased mobilisation of free fatty acids and release of catabolic hormones by caffeine suggest an influence of caffeine on ketogenesis.
Methods. In a controlled, double-blind intervention study, seven young healthy subjects received 10mL of tricaprylin (C8), tricaprin (C10), C8/C10 (50% C8, 50% C10), or coconut oil with or without 150 mg of caffeine, in 250mL of decaffeinated coffee, over ten interventions. At baseline and after every 40 minutes, for 4 h, ßHB and glucose in capillary blood as well as caffeine in saliva were measured. Furthermore, questionnaires were used to survey sensory properties, side effects, and awareness of hunger and satiety. Results. -e interventions with caffeine caused an increase in ßHB levels—in particular, the interventions with C8 highly impacted ketogenesis. -e effect decreased with increased chain lengths. All interventions showed a continuous increase in hunger and diminishing satiety. Mild side effects (total � 12) occurred during the interventions. Conclusions. -e present study demonstrated an influence of caffeine and MCTon ketogenesis. -eaddition of caffeine showed an additive effect on the ketogenic potential of MCT and coconut oil. C8 showed the highest ketogenicity.
Ziel dieser vorliegenden Arbeit ist, Kinder mit sexuell übergriffigem Verhalten in den Blick zu nehmen und sie als Adressat*innen der stationären Jugendhilfe zu begreifen.
Dies scheint umso wichtiger, wenn bedacht wird, dass Kinder mit problematischem sexuellem Verhalten gehäuft in der Jugendhilfe repräsentiert sind (vgl. Schuhrke/Arnold 2009, S. 187). Die bundesweite Kriminalstatistik von 2019 zählt 147 angezeigte Straftaten von Kindern gegen die sexuelle Selbstbestimmung pro 100.000 Einwohner bezogen auf die 8-14-Jährigen (vgl. PKS 2019, Z. 65 f.). Dies macht eine prozentuale Gesamtmenge von 6,9% aller Sexualdelikte aus (vgl. PKS Jahrbuch 2019, S. 21). Es ist jedoch denkbar, dass viele Straftaten gar nicht erst angezeigt werden (vgl. Elsner u.a. 2008, S. 4), da Kinder bis zum vollendeten 14. Lebensjahr laut dem §19 StGB strafunfähig sind und daher die Möglichkeit besteht, dass gar nicht erst eine Anzeige gestellt wird. Demnach kann unter Umständen von einer höheren Dunkelziffer ausgegangen werden. Schon die Zahl aus dem Hellfeld ist jedoch so hoch, dass das Problem strafunmündiger sexuell übergriffiger Kinder zunehmend mehr Beachtung gefunden hat, auch in der Wissenschaft.
Wind energy conversion systems have attracted considerable attention as a renewable energy source due to depleting fossil fuel reserves and environmental concerns as a direct consequence of using fossil fuel and nuclear energy sources. The increasing number of wind turbines increases the interest in efficient systems. The power output of a wind energy conversion system depends on the accuracy of the maximum power tracking system, as wind speed changes constantly throughout the day. Maximum power point tracking systems that do not require mechanical sensors to measure the wind speed offer several advantages over systems using mechanical sensors. In this paper four different approaches that do not use mechanical sensors to measure the wind speed will be presented; the assets and drawbacks of these systems are highlighted, and afterwards the examined algorithms will be compared based on different characteristics. Finally, based on the analysis, an evaluation is made as to which of the presented algorithms is the most promising.
Self-build small wind turbines are used for rural electrification in the developed and developing world as well as for educational purposes. To give an overview about self-build small wind turbines a systematic literature review was conducted. The identified literature deals with two different vertical and horizontal axis turbine designs. The vertical axis turbines are both prototypes while one of the horizontal axis designs, the design by Piggott is widely used in rural electrification projects. Different papers dealing with the optimization of the Piggott design exist. In retrospect the conduction of a holistic review was not possible due to limited resources and length of this review. Nevertheless it can give a quick overview and a starting point for further research.
Wind energy has steadily gained importance in the generation of renewable energy over the last 25 years. A wind turbine has an average life expectancy of about 25 years. After that, thermoplastic composite materials from the rotors, among other things, accumulate and have to be recycled. Previous methods, such as landfilling, incineration and pyrolysis, have not yet proven to be effective in terms of the circular economy because the recycled material cannot be reused for equivalent products. The use of thermoplastic materials can be a sensible alternative, as thermoplastic resins can be recycled almost without loss of value due to their properties. Recycling of fibreglass is also possible with less loss of stiffness. In the future, it will be crucial to scale up thermoplastic rotor blades and create a market for the recycled material.
Die vorliegende Arbeit beschäftigt sich mit Erlebnispädagogik und deren Relevanz für Erwachsene. Dabei fällt auf, dass erlebnispädagogische Träger, wie EXEO e.V. (vgl. EXEO e.V. o. D.), sich vorrangig auf Angebote für Kinder und Jugendliche spezialisiert haben. Erlebnispädagogik findet in außerschulischen Einrichtungen der Kinder- und Jugendhilfe statt. Im schulischen Kontext wird Erlebnispädagogik ergänzend zu der formalen Bildung, dem Unterricht, im Rahmen von Wandertagen, Klassenfahrten und Fortbildungen des Fachpersonals genutzt. Erlebnispädagogische Angebote wie von EXEO GmbH (vgl. EXEO GmbH o. D.) richten sich zusätzlich an Erwachsene. Die geringere Quantität der vorhandenen Fachliteratur zu nonformaler Bildung Erwachsener durch Erlebnispädagogik verdeutlicht, dass deren Altersgruppe in diesem Bildungssektor bislang wenig Aufmerksamkeit bekommen hat. Die praktische Erfahrung innerhalb des Arbeitsfeldes der Sozialen Arbeit zeigt, dass neben den Kindern und Jugendlichen, auch Erwachsene eine relevante Zielgruppe sind. Das steigende Interesse an Teamevents und Fortbildungsangeboten Erwachsener stellt neue Anforderungen an die Soziale Arbeit. So rücken diverse Methoden Sozialer Arbeit im Bereich der Erwachsenenbildung in den Vordergrund. Aus diesem Grund nimmt sich die vorliegende Arbeit dieser Altersgruppe an. Dabei entsteht die Frage, welchen Einfluss erlebnispädagogische Angebote auf die Resilienz Erwachsener hat. Inwieweit Resilienz entwickelt wird und warum diese auch für Erwachsene in ihrer Entwicklung und ihrem alltäglichen Leben vonnöten ist, wird im Laufe der Arbeit herausgearbeitet.
The Gaulwerk hydropower plant (HPP) has a design discharge of 3.5 m3/s and generates about 6.5 GWh per year. The HPP has been in operation since 1963 and uses the flow of two alpine streams. The HPP impounds a 300 m long reservoir with a 6.50 m high weir. The storage is completely filled with sediments and is classified as a valuable habitat for fauna and flora. Due to the sedimentation, the area upstream of the reservoir head inundates about two to three times per year during small flood events, leading to complaints from affected landowners and adjacent municipalities. To investigate sustainable solutions, a study of alternatives has been carried out in which three alternatives to im-prove both the sediment and flood situation are being investigated. In addition, the residual flow release will be adjusted and fish facilities realized in all alternatives. The paper will summarize the analysis of the alternatives encompassing the (1)
flood situation, (2) sediment management, (3) reha-bilitation measures of the hydraulic structures and their costs and (4) the environmental impact.
Additive manufacturing (AM) has been growing continuously over the past 20 years, enabling unprecedented tailoring to the anatomy of each patient. In Europe, custom-made devices qualify for an exemption and pass a simplified approval process. New technologies, like AM, provoke questions about the adequacy of the current regulatory framework for custom-made devices. This article addresses the regulatory requirements for such devices in Europe and discusses the implications for AM. It concludes that the legal framework for custom-made devices entails uncertainties which need to be resolved to guide manufacturers through the regulatory requirements, highlighting the specific areas of focus for AM.
Food-processing companies are controlled by societal influences and economic interests, but their efforts with regard to reducing food loss and waste are very different. This qualitative study aims to identify basic recommendations of good practice for the food-processing industry in order to prevent and handle food loss and waste. For this purpose, a comprehensive literature review was conducted in the field of food waste prevention and data was collected from thirteen German companies. The findings summarize the recommendations of good practice, which cover the entire supply chain from supplier to consumer and beyond. The analysis showed that the participating companies are already partially aware of operational measures, even if they are applied or mentioned without a systematic approach. Furthermore, the analysis revealed that most activities relate to internal matters, like processing, employees and utilization. However, the responsibility of foodprocessing companies does not end with internal processes to reduce food waste. The results show that some companies are already aware of their responsibility to be involved along the entire supply chain. Finally, the results show that the needs of consumers and suppliers must also be considered in order to reduce food waste, in addition to direct reduction measures. This paper highlights nine important stages and 53 basic recommendations for companies to address food loss and waste in order to improve their practices.
#BlackLivesMatter und #StopAsianHate sind nur zwei von vielen Hashtags, unter denen sich aktivistische Bewegungen gegen Rassismus in den letzten Jahren entwickelten. El-Mafaalani schlussfolgert: „Rassismus ist ein Thema des Mainstreams geworden.“ (2021, S. 10). Dies liegt allerdings nicht daran, dass das gesellschaftspolitische Interesse gestiegen ist, sondern daran, dass zunehmend BIPoC auf rassistische Diskriminierungsverhältnisse aufmerksam machen (vgl. ebd., S. 13 f.). Wie im Zitat der Antirassismus-Trainerin Tupoka Ogette deutlich wird, teilen Betroffene besonders nach schwerwiegenden Vorfällen in der Öffentlichkeit (z.B. der Anschlag in Hanau im Jahr 2020) ihre Erfahrungen mit, jedoch scheint es trotz dessen keine Veränderungen auf gesellschaftlicher und politischer Ebene zu geben. Die Soziale Arbeit hat als Menschenrechtsprofession den besonderen Auftrag, sich gegen Benachteiligung und für soziale Gerechtigkeit einzusetzen: Also auch Rassismus zu bekämpfen (vgl. Melter 2009, S. 107). Doch was passiert, wenn Fachkräfte selbst von Rassismus betroffen sind?
