However, key information such as sociodemographic characteristics of agents are often missing. This paper aims to compare four methods of classifying social attributes from text. Specifically, we are interested in estimating the gender of German social media creators. By using the example of a random sample of 200 YouTube channels, we compare several classification methods, namely (1) a survey among university staff, (2) a name dictionary method with the World Gender Name Dictionary as a reference list, (3) an algorithmic approach using the website gender-api.com, and (4) a Multinomial Naïve Bayes (MNB) machine learning technique. These different methods identify gender attributes based on YouTube channel names and descriptions in German but are adaptable to other languages. Our contribution will evaluate the share of identifiable channels, accuracy and meaningfulness of classification, as well as limits and benefits of each approach. We aim to address methodological challenges connected to classifying gender attributes for YouTube channels as well as related to reinforcing stereotypes and ethical implications.

Evidence From Germany's Refugee Allocation Policy T2 - Zweitveröffentlichungen der Universität Potsdam : Wirtschafts- und Sozialwissenschaftliche Reihe N2 - Emerging evidence has highlighted the important role of local contexts for integration trajectories of asylum seekers and refugees. Germany's policy of randomly allocating asylum seekers across Germany may advantage some and disadvantage others in terms of opportunities for equal participation in society. This study explores the question whether asylum seekers that have been allocated to rural areas experience disadvantages in terms of language acquisition compared to those allocated to urban areas. We derive testable assumptions using a Directed Acyclic Graph (DAG) which are then tested using large-N survey data (IAB-BAMF-SOEP refugee survey). We find that living in a rural area has no negative total effect on language skills. Further the findings suggest that the “null effect” is the result of two processes which offset each other: while asylum seekers in rural areas have slightly lower access for formal, federally organized language courses, they have more regular exposure to German speakers.

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.

We not only show that a continental-scale system is the cheapest, but also that systems on the national scale and below are possible at cost penalties of 20% or less. Transmission is key to low cost, but it is not necessary to vastly expand the transmission system. When electricity is transmitted only to balance fluctuations, the transmission grid size is comparable to today's, albeit with expanded cross-border capacities. The largest differences across scales concern land use and thus social acceptance: in the continental system, generation capacity is concentrated on the European periphery, where the best resources are. Regional systems, in contrast, have more dispersed generation. The key trade-off is therefore not between geographic scale and cost, but between scale and the spatial distribution of required generation and transmission infrastructure.

As a result, the use of technology in the learning processes of students of different disciplines became essential and the only way to teach, communicate and collaborate for months. In this crisis context, we conducted a longitudinal study in four German universities, in which we collected a total of 875 responses from students of information systems and music and arts at four points in time during the spring–summer 2020 semester. Our study focused on (1) the students’ acceptance of technology-mediated learning, (2) any change in this acceptance during the semester and (3) the differences in acceptance between the two disciplines. We applied the Technology Acceptance Model and were able to validate it for the extreme situation of the COVID-19 pandemic. We extended the model with three new variables (time flexibility, learning flexibility and social isolation) that influenced the construct of perceived usefulness. Furthermore, we detected differences between the disciplines and over time. In this paper, we present and discuss our study’s results and derive short- and long-term implications for science and practice.

T1 - The Role of Sustainable Investment in Climate Policy T2 - Postprints der Universität Potsdam : Wirtschafts- und Sozialwissenschaftliche Reihe N2 - Reaching the Sustainable Development Goals requires a fundamental socio-economic transformation accompanied by substantial investment in low-carbon infrastructure. Such a sustainability transition represents a non-marginal change, driven by behavioral factors and systemic interactions. However, typical economic models used to assess a sustainability transition focus on marginal changes around a local optimum, whichby constructionlead to negative effects. Thus, these models do not allow evaluating a sustainability transition that might have substantial positive effects. This paper examines which mechanisms need to be included in a standard computable general equilibrium model to overcome these limitations and to give a more comprehensive view of the effects of climate change mitigation. Simulation results show that, given an ambitious greenhouse gas emission constraint and a price of carbon, positive economic effects are possible if (1) technical progress results (partly) endogenously from the model and (2) a policy intervention triggering an increase of investment is introduced. Additionally, if (3) the investment behavior of firms is influenced by their sales expectations, the effects are amplified. The results provide suggestions for policy-makers, because the outcome indicates that investment-oriented climate policies can lead to more desirable outcomes in economic, social and environmental terms.

It grounds this analysis in a distinction between two basic models of democracy: simple and complex majoritarianism. These models differ not only in their electoral and party systems, but also in the style of coalition-building. Simple majoritarianism concentrates executive power in a single majority party; complex majoritarianism envisions the formation of shifting, issue-specific coalitions among multiple parties whose programs differ across multiple conflict dimensions. The latter pattern of coalition formation is very difficult to create and sustain under pure parliamentary government. A separation of powers between executive and legislature can facilitate such a pattern, while also achieving central goals of simple majoritarianism: identifiable cabinet alternatives before the election and stable cabinets afterward. The separation of powers can thus balance simple and complex majoritarianism in ways that are unavailable under parliamentarism. The article also compares the presidential and semi-parliamentary versions of the separation of powers. It argues that the latter has important advantages, e.g., when it comes to resolving inter-branch deadlock, as it avoids the concentration of executive power in a single human being.

This approach faces two challenges: the under-determination of the resulting democratic process and the idea of a trade-off between equal voter representation and government accountability. Linking conceptual with comparative analysis, the article argues that we can distinguish three ideal-typical varieties of the egalitarian vision of democracy, based on the stages at which majorities are formed. These varieties do not put different relative normative weight onto equality and accountability, but have different conceptions of both values and their reconciliation. The view that accountability is necessarily linked to clarity of responsibility', widespread in the comparative literature, is questioned - as is the idea of a general trade-off between representation and accountability. Depending on the vision of democracy, the two values need not be in conflict.

N2 - The article explores how recent changes in the governance of employment services in three European countries (Denmark, Germany and Norway) have influenced accountability relationships. The overall assumption in the growing literature about accountability is that the number of actors involved in accountability arrangements is rising, that accountability relationships are becoming more numerous and complex, and that these changes may lead to contradictory accountability relationships, and finally to ‘multi accountability disorder’. The article tries to explore these assumptions by analysing the different actors involved and the information requested in the new governance arrangements in all three countries. It concludes that the considerable changes in organizational arrangements and more managerial information demanded and provided have led to more shared forms of accountability. Nevertheless, a clear development towards less political or administrative accountability could not be observed.

This article analyses different crises' in immigration policies in Norway, Denmark and Germany along a descriptive framework of five different accountability types: political, administrative, legal, professional and social accountability. The exchanges of information, debate and their consequences between an actor and a forum are crucial to understanding how political-administrative action is carried out in critical situations. First, accountability dynamics emphasize conventional norms and values regarding policy change and, second, formal political responsibility does not necessarily lead to political consequences such as minister resignations in cases of misbehaviour. Consequences strongly depend on how accountability dynamics take place.

Analyzing accountability mechanisms through the lens of an institutional organizational approach and on the empirical basis of hospital privatization in Germany, the article contributes to the empirical and theoretical understanding of public accountability of private actors. The analysis suggests that accountability is not declining but rather multiplying. The shifts in the locus and content of accountability cause organizational stress for private hospitals.

T1 - Competition, contest, and cooperation BT - the analytic framework of the issue market N2 - Although party competition is widely regarded as an important part of a working democracy, it is rarely analysed in political science literature. This article discusses the basic properties of party competition, especially the patterns of interaction in contemporary party systems. Competition as a phenomenon at the macro level has to be carefully distinguished from contest and cooperation as the forms of interaction at the micro level. The article gives special attention to the creation of issue innovations. Contrary to existing approaches, I argue that not only responsiveness but also innovation are necessary to guarantee a workable democratic competition. Competition takes place on an issue market, where parties can discover voters’ demands. Combined with the concept of institutional veto points, the article presents hypotheses on how institutions shape the possibility for programmatic innovations.

BT - The participation of Italian women in the German labour market N2 - Already at the beginning of the fifties on the initiative of Italy, negotiations began between the Italian and German governments for the recruitment of migrant-workers, which ended in 1955 with a bilateral agreement between the two countries. Through this recruitment policy and because of the labour-market (Industry and Building) the Italian migration was composed prevalently of men. Female immigration happened in the setting of family reunification and less as an independent movement project. After years of stagnation of italian emigration in the eighties it may also be noted that, since the early nineties, there has been a revival of immigration to Germany. This and modernisation processes in Italy changed the gender composition of the Italian immigration flow to Germany: the distance between male and female immigration is decreasing. A peculiarity of the Italians in Germany is the low occupational participation of women in comparison with other women from EU countries. However, we could observe regional differences, which depend on the migration typologies and the dominating economic structure in the areas. The paper will analyse this different aspects (immigration-processes, migrant-typologies and labour-market participation) by female Italian migrants.
