  abstract  = {The large literature that aims to find evidence of climate migration delivers mixed findings. This meta-regression analysis i) summarizes direct links between adverse climatic events and migration, ii) maps patterns of climate migration, and iii) explains the variation in outcomes. Using a set of limited dependent variable models, we meta-analyze thus-far the most comprehensive sample of 3,625 estimates from 116 original studies and produce novel insights on climate migration. We find that extremely high temperatures and drying conditions increase migration. We do not find a significant effect of sudden-onset events. Climate migration is most likely to emerge due to contemporaneous events, to originate in rural areas and to take place in middle-income countries, internally, to cities. The likelihood to become trapped in affected areas is higher for women and in low-income countries, particularly in Africa. We uniquely quantify how pitfalls typical for the broader empirical climate impact literature affect climate migration findings. We also find evidence of different publication biases.},

  abstract  = {Unser modernes Strafrechtsbild ist gepr{\"a}gt von dem Gedanken, dass das Strafrecht den B{\"u}rgern ein freies und friedliches Zusammenleben unter Gew{\"a}hrleistung aller verfassungsrechtlich garantierten Grundrechte sichert. Der Einsatz des Strafrechts bedarf der Legitimation und darf nicht aus moralischen Vorstellungen oder Gedanken abgeleitet werden. Strafbar kann es demnach nicht sein, wenn ein Rechtsgutstr{\"a}ger {\"u}ber ein ihm disponibles Rechtsgut frei verf{\"u}gt. Oftmals stehen hierbei der strafrechtliche Lebensschutz und das Selbstbestimmungsrecht des Einzelnen in einem Spannungsverh{\"a}ltnis. Die vorliegende Arbeit hat untersucht, wie sich dieses Spannungsverh{\"a}ltnis in der h{\"o}chstrichterlichen Judikatur entwickelt hat und wie es nunmehr gel{\"o}st wird. Konkret stellt sich hierbei die Frage, wie es strafrechtlich bewertet wurde, wenn jemand einen T{\"o}tungserfolg mitverursacht hat, der zugleich auf einem freiverantwortlichen Willensentschluss des Opfers beruhte.},

  abstract  = {The increasing development of antibiotic resistance in bacteria has been a major problem for years, both in human and veterinary medicine. Prophylactic measures, such as the use of vaccines, are of great importance in reducing the use of antibiotics in livestock. These vaccines are mainly produced based on formaldehyde inactivation. However, the latter damages the recognition elements of the bacterial proteins and thus could reduce the immune response in the animal. An alternative inactivation method developed in this work is based on gentle photodynamic inactivation using carbon nanodots (CNDs) at excitation wavelengths λex > 290 nm. The photodynamic inactivation was characterized on the nonvirulent laboratory strain Escherichia coli K12 using synthesized CNDs. For a gentle inactivation, the CNDs must be absorbed into the cytoplasm of the E. coli cell. Thus, the inactivation through photoinduced formation of reactive oxygen species only takes place inside the bacterium, which means that the outer membrane is neither damaged nor altered. The loading of the CNDs into E. coli was examined using fluorescence microscopy. Complete loading of the bacterial cells could be achieved in less than 10 min. These studies revealed a reversible uptake process allowing the recovery and reuse of the CNDs after irradiation and before the administration of the vaccine. The success of photodynamic inactivation was verified by viability assays on agar. In a homemade flow photoreactor, the fastest successful irradiation of the bacteria could be carried out in 34 s. Therefore, the photodynamic inactivation based on CNDs is very effective. The membrane integrity of the bacteria after irradiation was verified by slide agglutination and atomic force microscopy. The method developed for the laboratory strain E. coli K12 could then be successfully applied to the important avian pathogens Bordetella avium and Ornithobacterium rhinotracheale to aid the development of novel vaccines.},

  abstract  = {Models are useful tools for understanding and predicting ecological patterns and processes. Under ongoing climate and biodiversity change, they can greatly facilitate decision-making in conservation and restoration and help designing adequate management strategies for an uncertain future. Here, we review the use of spatially explicit models for decision support and to identify key gaps in current modelling in conservation and restoration. Of 650 reviewed publications, 217 publications had a clear management application and were included in our quantitative analyses. Overall, modelling studies were biased towards static models (79\%), towards the species and population level (80\%) and towards conservation (rather than restoration) applications (71\%). Correlative niche models were the most widely used model type. Dynamic models as well as the gene-to-individual level and the community-to-ecosystem level were underrepresented, and explicit cost optimisation approaches were only used in 10\% of the studies. We present a new model typology for selecting models for animal conservation and restoration, characterising model types according to organisational levels, biological processes of interest and desired management applications. This typology will help to more closely link models to management goals. Additionally, future efforts need to overcome important challenges related to data integration, model integration and decision-making. We conclude with five key recommendations, suggesting that wider usage of spatially explicit models for decision support can be achieved by 1) developing a toolbox with multiple, easier-to-use methods, 2) improving calibration and validation of dynamic modelling approaches and 3) developing best-practise guidelines for applying these models. Further, more robust decision-making can be achieved by 4) combining multiple modelling approaches to assess uncertainty, and 5) placing models at the core of adaptive management. These efforts must be accompanied by long-term funding for modelling and monitoring, and improved communication between research and practise to ensure optimal conservation and restoration outcomes.},

  abstract  = {State-of-the-art organic solar cells exhibit power conversion efficiencies of 18\% and above. These devices benefit from the suppression of free charge recombination with regard to the Langevin limit of charge encounter in a homogeneous medium. It is recognized that the main cause of suppressed free charge recombination is the reformation and resplitting of charge-transfer (CT) states at the interface between donor and acceptor domains. Here, we use kinetic Monte Carlo simulations to understand the interplay between free charge motion and recombination in an energetically disordered phase-separated donor-acceptor blend. We identify conditions for encounter-dominated and resplitting-dominated recombination. In the former regime, recombination is proportional to mobility for all parameters tested and only slightly reduced with respect to the Langevin limit. In contrast, mobility is not the decisive parameter that determines the nongeminate recombination coefficient, k(2), in the latter case, where k2 is a sole function of the morphology, CT and charge-separated (CS) energetics, and CT-state decay properties. Our simulations also show that free charge encounter in the phase-separated disordered blend is determined by the average mobility of all carriers, while CT reformation and resplitting involves mostly states near the transport energy. Therefore, charge encounter is more affected by increased disorder than the resplitting of the CT state. As a consequence, for a given mobility, larger energetic disorder, in combination with a higher hopping rate, is preferred. These findings have implications for the understanding of suppressed recombination in solar cells with nonfullerene acceptors, which are known to exhibit lower energetic disorder than that of fullerenes.},

Importantly, the photoinduced level shifts occur in the organic component, including the first molecular layer in direct contact with the perovskite. This is caused by charge-carrier accumulation within the organic semiconductor under illumination and the weak electronic coupling between the junction components.},

Dies gilt insbesondere im Zusammenhang mit Inklusion, deren Relevanz nicht zuletzt durch das {\"U}bereinkommen der Vereinten Nationen {\"u}ber die Rechte von Menschen mit Behinderung gegeben ist. Diese Arbeit diskutiert zahlreiche lernrelevante Besonderheiten im Kontext von Autismus und zeigt Diskrepanzen zu den nicht immer ausreichend angemessenen institutionellen Lehrkonzepten. Eine zentrale These ist hierbei, dass die ungew{\"o}hnlich intensive Aufmerksamkeit von Autist*innen f{\"u}r ihre Spezialinteressen daf{\"u}r genutzt werden kann, das Lernen mit fremdgestellten Inhalten zu erleichtern. Darauf aufbauend werden L{\"o}sungsans{\"a}tze diskutiert, welche in einem neuartigen Konzept f{\"u}r ein digitales mehrger{\"a}tebasiertes Lernspiel resultieren. Eine wesentliche Herausforderung bei der Konzeption spielbasierten Lernens besteht in der ad{\"a}quaten Einbindung von Lerninhalten in einen fesselnden narrativen Kontext. Am Beispiel von {\"U}bungen zur emotionalen Deutung von Mimik, welche f{\"u}r das Lernen von sozioemotionalen Kompetenzen besonders im Rahmen von Therapiekonzepten bei Autismus Verwendung finden, wird eine angemessene Narration vorgestellt, welche die st{\"o}rungsarme Einbindung dieser sehr speziellen Lerninhalte erm{\"o}glicht. Die Effekte der einzelnen Konzeptionselemente werden anhand eines prototypisch entwickelten Lernspiels untersucht. Darauf aufbauend zeigt eine quantitative Studie die gute Akzeptanz und Nutzerfreundlichkeit des Spiels und belegte vor allem die Verst{\"a}ndlichkeit der Narration und der Spielelemente. Ein weiterer Schwerpunkt liegt in der minimalinvasiven Untersuchung m{\"o}glicher St{\"o}rungen des Spielerlebnisses durch den Wechsel zwischen verschiedenen Endger{\"a}ten, f{\"u}r die ein innovatives Messverfahren entwickelt wurde. Im Ergebnis beleuchtet diese Arbeit die Bedeutung und die Grenzen von spielbasierten Ans{\"a}tzen f{\"u}r autistische Lernende. Ein großer Teil der vorgestellten Konzepte l{\"a}sst sich auf andersartige Lernszenarien {\"u}bertragen.

Ich {\"u}berlegte zudem, ob eine Publikation mich als Arbeitnehmerin wie Privatperson angreifbar machen w{\"u}rde. Doch nach dem Erscheinen der Portal 1/2021 erreichten uns in der Pressestelle viele Danksagungen und Ermunterungen aus ganz unterschiedlichen Bereichen der Universit{\"a}t. Das Thema schien einen Nerv getroffen zu haben, was uns veranlasste, eine komplette Ausgabe zu diesem Thema zu produzieren. So halten Sie nun die Portal „Familie und Beruf" in den H{\"a}nden! Familie beschr{\"a}nkt sich im Jahr 2021 dabei nicht auf „Mutter, Vater, Kind", sondern manifestiert sich vielmehr in großer Diversit{\"a}t. Wir haben mit Menschen gesprochen, die in gleichgeschlechtlichen Partnerschaften leben, die Kinder adoptiert haben oder die ihr Haustier als Familienmitglied lieben; mit Alleinerziehenden genauso wie mit Paaren, die traumatisierte Pflegekinder großziehen. Dieses Heft zeigt eine Vielfalt unserer Kolleginnen und Kollegen, unserer Studierenden und macht deutlich: Familie ist bunt. Unterm Strich k{\"o}nnen wir festhalten, dass heute viel Flexibilit{\"a}t von uns verlangt wird - daheim wie im B{\"u}ro, H{\"o}rsaal oder Labor. Die Herausforderung ist und bleibt kontinuierlich: Verschiedene Lebensbereiche m{\"u}ssen in wechselnden Lebensphasen unter einen Hut gebracht werden. Wenn diese Portal vor Ihnen liegt, werde ich aufgrund einer befristeten Anstellung nicht mehr Teil der Uni Potsdam sein. Daf{\"u}r ist Dr. Jana Scholz aus ihrer Elternzeit zur{\"u}ckgekehrt. Was mich mit ihr - und mutmaßlich auch mit Ihnen als Leserinnen und Leser - doch bleibend verbindet, ist das Bestreben, Familie und Beruf in Einklang zu bringen. Alles Gute! (Sandy Bossier-Steuerwald) Liebe Leserinnen und Leser, es bleibt nicht viel zu erg{\"a}nzen. Außer: Falls Sie nach dem Lesen dieser Ausgabe den Eindruck haben sollten, dass Familie vor allem herausfordernd und kr{\"a}ftezehrend ist - dann haben wir uns missverstanden. Dem ist nat{\"u}rlich nicht so! Familie ist auch N{\"a}he, Zusammenhalt, Spaß, Humor und vieles mehr. An den Herausforderungen, die sie an uns und unseren Beruf stellt, k{\"o}nnen wir wachsen. Und dies gelingt besonders, wenn wir ein Netz von Freunden, Kolleginnen und Vorgesetzen haben, das uns dabei unterst{\"u}tzt. Wie immer bietet die Portal {\"u}ber den Titel hinaus einen bunten Strauß an Geschichten: von magnetischen Kunstwerken, mit denen Studierende die Stadt versch{\"o}nern, {\"u}ber eine angehende Rabbinerin, die Feminismus in die Gemeinden bringen will, bis zu den urzeitlichen sizilianischen Zwergelefanten, die {\"u}ber Jahrtausende schrumpften, bis sie vor 19.000 Jahren ganz verschwanden. Ich w{\"u}nsche Ihnen viel Vergn{\"u}gen beim Lesen! (Dr. Jana Scholz)},

  abstract  = {On October 20, 1911, the Norwegian Roald Amundsen left the safe base camp "Framheim" at the Bay of Whales together with four other explorers and 52 sledge dogs to be the first person to reach the South Pole. Ahead of them lay the perpetual ice at temperatures of 20 to 30 degrees Celsius below zero and a distance of 1,400 kilometers. After eight weeks, the group reached its destination on December 13. The men planted the Norwegian flag in the lonely snow and shortly afterwards set off to make their way back - celebrated, honored as conquerors of the South Pole and laden with information and knowledge from the world of Antarctica. The voyage of Amundsen and his companions is undoubtedly so extraordinary because the five proved that it was possible and were the first to succeed. It is, however, also a symbol of what enables humans to push the boundaries of their world: the urge to set out into the unknown, to discover what has not yet been found, explored, and described. What distinguishes science - even before each discovery and new knowledge - is the element of departure. Questioning apparent certainties, taking a critical look at outdated knowledge, and breaking down encrusted thought patterns is the starting point of exploratory curiosity. And to set out from there for new knowledge is the essence of scientific activities - neither protected nor supported by the reliable and known. Probing, trying, courageously questioning, and sensing that the solid ground, which still lies hidden, can only be reached again in this way. "Research is always a departure for new shoreless waters," said chemist Prof. Dr. Hans-J{\"u}rgen Quadbeck-Seeger. Leaving behind the safe harbor, trusting that new shores are waiting and can be reached is the impetus that makes science so important and valuable. For the current issue of the University of Potsdam's research magazine, we looked over the shoulders of some researchers as they set out on new research journeys - whether in the lab, in the library, in space, or in the mind. Astrophysicist Lidia Oskinova, for example, uses the Hubble telescope to search for particularly massive stars, while hydrologist Thorsten Wagener is trying to better understand the paths of water on Earth. Economists and social scientists such as Elmar Kriegler and Maik Heinemann are researching in different projects what politics can do to achieve a turnaround in climate policy and stop climate change. Time and again, however, such departures are themselves the focus of research: And a group of biologists and environmental scientists is investigating how nature revives forest fire areas and how the newly emerging forests can become more resilient to future fires. Since - as has already been said - a departure is inherent in every research question, this time the entire issue of "Portal Wissen" is actually devoted to the cover topic. And so we invite you to set out with Romance linguist Annette Gerstenberg to research language in old age, with immunologist Katja Hanack to develop a quick and safe SARS-CoV-2 test, and with the team of the Potsdam Center for Industry 4.0 to the virtual factory of tomorrow. And we will show you how evidence- based economic research can inform and advise politicians, and how a warning system is intended to prevent future accidents involving cyclists. So, what are you waiting for?!},

  abstract  = {Am 20. Oktober 1911 verließ der Norweger Roald Amundsen gemeinsam mit vier Begleitern und 52 Schlittenhunden das sichere Lager „Framheim" in der „Bucht der Wale", um als erster Mensch den S{\"u}dpol zu erreichen. Vor ihnen lagen das ewige Eis bei -20 bis -30 Grad Celsius und eine Strecke von 1.400 Kilometern. Nach acht Wochen erreichte die Gruppe am 13. Dezember ihr Ziel. Die M{\"a}nner pflanzten die norwegische Fahne in den einsamen Schnee und machten sich wenig sp{\"a}ter auf den R{\"u}ckweg - ruhmreich, geehrt als Eroberer des S{\"u}dpols und beladen mit Informationen und Wissen aus der Welt der Antarktis. Die Reise von Amundsen und seinen Begleitern ist fraglos so außergew{\"o}hnlich, weil durch sie bewiesen wurde, dass sie m{\"o}glich ist, und weil die f{\"u}nf die ersten waren, denen sie gelang. Sie ist aber auch Sinnbild f{\"u}r das, was dem Menschen erlaubt, die Grenzen seiner Welt immer weiter zu verschieben: der Drang, ins Unbekannte aufzubrechen, zu entdecken, was noch nicht gefunden, erforscht und beschrieben ist. Was Wissenschaft - noch vor jeder Entdeckung und allem neuen Wissen - auszeichnet, ist der Aufbruch. Scheinbare Gewissheiten infrage zu stellen, angestaubtes Wissen kritisch zu betrachten und verkrustete Denkstrukturen aufzubrechen, ist der Anfangspunkt forschender Neugier. Und von dort aufzubrechen zu neuer Erkenntnis, das Wesen wissenschaftlichen Tuns. Ungesch{\"u}tzt und -gest{\"u}tzt vom Verl{\"a}sslichen, Bekannten. Tastend, versuchend, mutig fragend, ahnend, dass nur so wieder fester Boden zu erreichen ist, der heute noch verborgen liegt. „Forschung ist immer Aufbruch zu neuen Uferlosigkeiten", sagte der Chemiker Prof. Dr. Hans- J{\"u}rgen Quadbeck-Seeger. Den sicheren Hafen hinter sich lassen, darauf vertrauend, dass neue Ufer warten und erreichbar sind - das ist der Antrieb, der Wissenschaft so wichtig und wertvoll macht. In der aktuellen Ausgabe des Forschungsmagazins der Universit{\"a}t Potsdam haben wir einigen Wissenschaftlerinnen und Wissenschaftlern {\"u}ber die Schulter geschaut, wenn sie zu neuen Forschungsreisen aufbrechen - ob im Labor, in der Bibliothek, im All oder im Geist. So sucht die Astrophysikerin Lidia Oskinova mithilfe des Hubble-Teleskops nach besonders massereichen Sternen, w{\"a}hrend der Hydrologe Thorsten Wagener versucht, die Wege des Wassers auf der Erde besser zu verstehen. Wirtschafts- und Sozialwissenschaftler wie Elmar Kriegler und Maik Heinemann erforschen in verschiedensten Projekten, was die Politik tun kann, um die Klimawende zu schaffen und den Klimawandel zu stoppen. Und Verwaltungswissenschaftlerinnen wie Sabine Kuhlmann schauen, wie das „Stadtmachen" von morgen funktioniert - und bringen sich sogar pers{\"o}nlich ein. Immer wieder stehen aber auch Aufbr{\"u}che selbst im Fokus der Forschung: Ein Team um die Historiker Dominik Geppert und Frank B{\"o}sch geht etwa der Frage nach, ob und wie nach dem Umbruch 1989/90 in der ostdeutschen Wissenschaftslandschaft ein Neuanfang erfolgte - und zwar am Beispiel der Universit{\"a}t Potsdam selbst. Die Amerikanistin Verena Adamik analysiert anhand von Romanen, welchen Einfluss Literatur darauf hat, ob Menschen zu neuen Lebensformen aufbrechen und utopische Kommunen gr{\"u}nden. Und eine Gruppe von Biologen und Umweltwissenschaftlern untersucht, wie die Natur Waldbrandfl{\"a}chen wiederbelebt - und auf welche Weise die neu entstehenden W{\"a}lder gegen k{\"u}nftige Feuer gewappnet werden k{\"o}nnen. Da - wie gesagt - jeder Forschungsfrage ein Aufbruch innewohnt, steht diesmal eigentlich die ganze Ausgabe unter dem Titelthema. Und so laden wir Sie ein aufzubrechen: mit der Romanistin Annette Gerstenberg zur Erforschung der Sprache im Alter, mit der Immunologin Katja Hanack zur Entwicklung eines schnellen und sicheren SARS-CoV-2-Tests oder mit dem Team des Zentrums Industrie 4.0 Potsdam in die virtuelle Fabrik von morgen. Wir zeigen Ihnen, wie volkswirtschaftliche Forschung auf der Grundlage von Fakten informieren und Politik beraten kann, wie ein Warnsystem k{\"u}nftig Unf{\"a}lle mit Radfahrern verhindern soll und was eine 300 Jahre alte Landesbeschreibung Brandenburgs uns heute noch zu sagen hat. Worauf warten Sie noch?!},

  abstract  = {We traced diatom composition and diversity through time using diatom-derived sedimentary ancient DNA (sedaDNA) from eastern continental slope sediments off Kamchatka (North Pacific) by applying a short, diatom-specific marker on 63 samples in a DNA metabarcoding approach. The sequences were assigned to diatoms that are common in the area and characteristic of cold water. SedaDNA allowed us to observe shifts of potential lineages from species of the genus Chaetoceros that can be related to different climatic phases, suggesting that pre-adapted ecotypes might have played a role in the long-term success of species in areas of changing environmental conditions. These sedaDNA results complement our understanding of the long-term history of diatom assemblages and their general relationship to environmental conditions of the past. Sea-ice diatoms (Pauliella taeniata [Grunow] Round \& Basson, Attheya septentrionalis [ostrup] R. M. Crawford and Nitzschia frigida [Grunow]) detected during the late glacial and Younger Dryas are in agreement with previous sea-ice reconstructions. A positive correlation between pennate diatom richness and the sea-ice proxy IP25 suggests that sea ice fosters pennate diatom richness, whereas a negative correlation with June insolation and temperature points to unfavorable conditions during the Holocene. A sharp increase in proportions of freshwater diatoms at similar to 11.1 cal kyr BP implies the influence of terrestrial runoff and coincides with the loss of 42\% of diatom sequence variants. We assume that reduced salinity at this time stabilized vertical stratification which limited the replenishment of nutrients in the euphotic zone.},

  abstract  = {This chapter argues not only that there is no European Sonderweg (or 'special way') when it comes to the law of state immunity but that there ought not to be one. Debates within The Hague Conference on Private International Law in the late 1990s and those leading to the adoption of the 2002 UN Convention on Jurisdictional Immunities of States, as well as the development of the EU Brussels Regulation on Jurisdiction and Enforcement, as amended in 2015, all demonstrate that state immunity was not meant to be limited by such treaties but 'safeguarded'. Likewise, there is no proof that regional European customary law limits state immunity when it comes to ius cogens violations, as Italy and (partly) Greece are the only European states denying state immunity in such cases while the European Court of Human Rights has, time and again, upheld a broad concept of state immunity. It therefore seems unlikely that in the foreseeable future a specific European customary law norm on state immunity will develop, especially given the lack of participation in such practice by those states most concerned by the matter, including Germany. This chapter considers the possible legal implications of the jurisprudence of the Italian Constitutional Court for European military operations (if such operations went beyond peacekeeping). These implications would mainly depend on the question of attribution: if one where to assume that acts undertaken within the framework of military operations led by the EU were to be, at least also, attributable to the troop-contributing member states, the respective troop-contributing state would be entitled to enjoy state immunity exactly to the same degree as in any kind of unilateral military operations. Additionally, some possible perspectives beyond Sentenza 238/2014 are examined, in particular concerning the redress awarded by domestic courts 'as long as' neither the German nor the international system grant equivalent protection to the victims of serious violations of international humanitarian law committed during World War II. In the author's opinion, strengthening the jurisdiction of international courts and tribunals, bringing interstate cases for damages before the International Court of Justice, as well as providing for claims commissions where individual compensation might be sought for violations of international humanitarian law would be more useful and appropriate mechanisms than denying state immunity.},

  abstract  = {As overconsumption has negative effects on ecological balance, social equality, and individual well-being, reducing consumption levels among the materially affluent is an emerging strategy for sustainable development. Today's youth form a crucial target group for intervening in unsustainable overconsumption habits and for setting the path and ideas on responsible living. This article explores young people's motivations for engaging in three behavioural patterns linked to anti-consumption (voluntary simplicity, collaborative consumption, and living within one's means) in relation to sustainability. Applying a qualitative approach, laddering interviews reveal the consequences and values behind the anti-consumption behaviours of young people of ages 14 to 24 according to a means-end chains analysis. The findings highlight potential for and the challenges involved in motivating young people to reduce material levels of consumption for the sake of sustainability. Related consumer policy tools from the fields of education and communication are identified. This article provides practical implications for policy makers, activists, and educators. Consumer policies may strengthen anti-consumption among young people by addressing individual benefits, enabling reflection on personal values, and referencing credible narratives. The presented insights can help give a voice to young consumers, who struggle to establish themselves as key players in shaping the future consumption regime.},
