TY - GEN A1 - Geiß, Robin A1 - Siegrist, Michael T1 - Has the armed conflict in Afghanistan affected the rules on the conduct of hostilities? T2 - Postprints der Universität Potsdam Rechtswissenschaftliche Reihe N2 - The armed conflict in Afghanistan since 2001 has raised manifold questions pertaining to the humanitarian rules relative to the conduct of hostilities. In Afghanistan, as is often the case in so-called asymmetric conflicts, the geographical and temporal boundaries of the battlefield, and the distinction between civilians and fighters, are increasingly blurred. As a result, the risks for both civilians and soldiers operating in Afghanistan are high. The objective of this article is to assess whether - and if so how much - the armed conflict in Afghanistan has affected the application and interpretation of the principles of distinction, proportionality, and precaution - principles that form the core of legal rules pertaining to the conduct of hostilities.

Their arrival was captured by a heavy media presence, and very quickly doubts were raised by right-wing tabloids and politicians about their age. In this article, I explore the arguments underpinning the Dubs campaign and the media coverage of the children’s arrival as a starting point for interrogating representational practices around children who seek asylum. I illustrate how the campaign was premised on a universal politics of childhood that inadvertently laid down the terms on which these children would be given protection, namely their innocence. The universality of childhood fuels public sympathy for child asylum-seekers, underlies the ‘child first, migrant second’ approach advocated by humanitarian organisations, and it was a key argument in the ‘Dubs amendment’. Yet the campaign highlights how representations of child asylum-seekers rely on codes that operate to identify ‘unchildlike’ children. As I show, in the context of the criminalisation of undocumented migrants‘, childhood is no longer a stable category which guarantees protection, but is subject to scrutiny and suspicion and can, ultimately, be disproved.

Urgent calls have been made to improve vaccine outreach to migrants, however, there is limited evidence on effective approaches, especially using social media. We assessed a targeted, low-cost, Facebook campaign disseminating COVID-19 vaccine information among Arabic, Turkish and Russian speakers in Germany (N = 888,994). As part of the campaign, we conducted two randomized, online experiments to assess the impact of the advertisement (1) language and (2) depicted messenger (government authority, religious leader, doctor or family). Key outcomes included reach, click-through rates, conversion rates and cost-effectiveness. Within 29 days, the campaign reached 890 thousand Facebook users. On average, 2.3 individuals accessed the advertised COVID-19 vaccination appointment tool for every euro spent on the campaign. Migrants were 2.4 (Arabic), 1.8 (Russian) and 1.2 (Turkish) times more likely to click on advertisements translated to their native language compared to German-language advertisements. Furthermore, findings showed that government representatives can be more successful in engaging migrants online compared to other messengers, despite common claims of lower trust in government institutions among migrants. This study highlights the potential of tailored, and translated, vaccination campaigns on social media for reaching migrants who may be left out by traditional media campaigns.

Das wirft die Frage auf, wie das notwendige Wissen erzeugt, bewahrt, verteilt und auffindbar gemacht werden kann. Ein solches Wissensmanagement kann die Arbeit der Behörden qualitativ verbessern und effizienter machen. Dennoch wird Wissen in der Verwaltungspraxis bisher nur unzureichend gemanagt. Ein systematisches Wissensmanagement erfordert personelle, finanzielle und technische Ressourcen. Sind diese nicht vorhanden, können Verwaltungen zunächst auf einzelne Instrumente des Wissensmanagements zurückgreifen, um ihre Arbeit mit begrenztem Aufwand zu verbessern.

This paper reviews the strengths and weaknesses of eight novel, digital data sources along five domains: reliability, validity, scope, access and ethics. The review highlights the opportunities for migration scholars but also stresses the ethical and empirical challenges. This review intends to be of service to researchers and policy analysts alike and help them navigate this new and increasingly complex field.

A1 - Moroz, George A. T1 - Universal attractors in language evolution provide evidence for the kinds of efficiency pressures involved T2 - Zweitveröffentlichungen der Universität Potsdam : Philosophische Reihe N2 - Efficiency is central to understanding the communicative and cognitive underpinnings of language. However, efficiency management is a complex mechanism in which different efficiency effects-such as articulatory, processing and planning ease, mental accessibility, and informativity, online and offline efficiency effects-conspire to yield the coding of linguistic signs. While we do not yet exactly understand the interactional mechanism of these different effects, we argue that universal attractors are an important component of any dynamic theory of efficiency that would be aimed at predicting efficiency effects across languages. Attractors are defined as universal states around which language evolution revolves. Methodologically, we approach efficiency from a cross-linguistic perspective on the basis of a world-wide sample of 383 languages from 53 families, balancing all six macro-areas (Eurasia, North and South America, Australia, Africa, and Oceania). We explore the grammatical domain of verbal person-number subject indexes. We claim that there is an attractor state in this domain to which languages tend to develop and tend not to leave if they happen to comply with the attractor in their earlier stages of evolution. The attractor is characterized by different lengths for each person and number combination, structured along Zipf's predictions. Moreover, the attractor strongly prefers non-compositional, cumulative coding of person and number. On the basis of these and other properties of the attractor, we conclude that there are two domains in which efficiency pressures are most powerful: strive towards less processing and articulatory effort. The latter, however, is overridden by constant information flow. Strive towards lower lexicon complexity and memory costs are weaker efficiency pressures for this grammatical category due to its order of frequency.

BT - Friendship preferences and the quantity and quality of mutual friendships T2 - Postprints der Universität Potsdam : Humanwissenschaftliche Reihe N2 - Empirical studies already examined various facets of the friendship construct. Building on this, the present study examines the questions of how the number of friendships and their quality differ between students with and without SEN and whether a homophily-effect can be identified. The sample consists of 455 fourth-graders from 28 inclusive classes in Austria. The results indicate that students with SEN have fewer friends than students without SEN. Furthermore, students without SEN preferred peers without SEN as a friend. This homophily-effect was shown for students with SEN, too. However, students with and without SEN rated the quality of their friendships similarly and no interactions between the SEN status of oneself or of the friend was found for the quality of the friendship. The results show that, in the context of inclusion, the issue of friendship needs to be increasingly addressed to improve the situation of students with SEN.

T2 - Postprints der Universität Potsdam : Wirtschafts- und Sozialwissenschaftliche Reihe N2 - The article explores Europeanisation as an effect of European political integration, a process driven by struggles over the legitimate political and social order that is to prevail in Europe. Firstly, an analytic framework is constructed, drawing on insights from Pierre Bourdieu’s work on similar struggles over nation-stateness. Secondly, the mechanisms identified are used to assess the role played by economic experts and expertise in the process of European political integration. It is argued that concepts arising from economic disciplines, agents educated in economics, and practising economic professionals influence European political integration and have benefited from Europeanisation initiated by this process. Special emphasis is placed on strategies of integrating Europe by law or by market, on governing Europe using economic expertise, on the role played by economic academia in researching and objectifying Europe, and on staffing European institutions with economists.

As an ever-increasing number of policy issues are identified as an inherently ill-structured and intractable type of wicked problem, the question of what policy analysis sets out to accomplish has emerged as more central than ever. If solving wicked problems is beyond reach, research on wicked problems needs to provide a clearer understanding of the alternatives. The article identifies and explicates three distinguishable strategies of problem governance: coping, taming and solving. It shows that their intellectual premises and practical implications clearly contrast in core respects. The article argues that none of the identified strategies of problem governance is invariably more suitable for dealing with wicked problems. Rather than advocate for some universally applicable approach to the governance of wicked problems, the article asks under what conditions different ways of governing wicked problems are analytically reasonable and normatively justified. It concludes that a more systematic assessment of alternative approaches of problem governance requires a reorientation of the debate away from the conception of wicked problems as a singular type toward the more focused analysis of different dimensions of problem wickedness.
