Föderalismus, Dezentralisierung und Performanz. Eine makroquantitative Analyse der Leistungsfähigkeit territorialer Politikorganisation in entwickelten Demokratien

Does federalism matter? We develop a theoretical model on the causal relationships between federalism, decentralization and system performance by merging the two literatures on political and fiscal federalism. The model is then tested in a quantitative analysis, including the OECD countries. We find that, consistent with our model, federalism and decentralization are different dimensions of the territorial organization of politics. Decentralization has positive effects; federalism tends to result in either no or a negative performance effect.     

A tale of three bridges: agency and agonism in peace building

This article explores agonistic processes of peace, which are situated within and constitutive of different spaces and places. Three contested cities, Sarajevo, Mostar and Vi?egrad in Bosnia-Herzegovina, provide us with local sites where peace and peace building in various forms ‘take place’ as people come together in collective action. Through a close reading of three symbolically and materially important bridges in the towns, we reveal meaning-making processes, as agentive subjects struggle around competing claims in the post-conflict everyday world. The collective, situated and fleeting agency that we explore through the Arendtian notion of ‘space of appearance’ invests space with meaning, belonging and identity. Thus, this article grapples with agonistic peace as it manifests itself in materiality and spatial practices. We use the social and material spaces of the city to locate agency and agonism in peace building as they relate to the conflict legacy in Mostar, Vi?egrad and Sarajevo in order to advance the critical peace research agenda.     

The Effectiveness of Inputs in Primary Education: Insights from Recent Student Surveys for Sub-Saharan Africa

With SACMEQ and PASEC there are now two large data bases available on student achievement, socio-economic background and school and teacher characteristics in both anglophone and francophone sub-Saharan Africa. A joint analysis of PASEC and SACMEQ in a common education production function framework allows us to estimate the impact of educational inputs on student achievement in 21 sub-Saharan African countries and to compare our results with those of earlier empirical studies for education systems in Africa and other world regions. In our analysis we focus on school equipment, teacher quality and class organisation. The issue of teacher and student incentives cannot be adequately addressed with the given data. Our results are based on a traditional retrospective analysis of student achievement in PASEC and SACMEQ countries. In contrast to the ‘nothing works’ result from most industrialized countries' studies we find robust positive correlations of achievement test scores and the possession of textbooks and negative correlations with teaching in shifts. The most striking result is the weak or even absent correlation of achievement test scores and teacher education and professional training. However, some differences between francophone and anglophone education systems can be observed in this context if differences in the sampling methodology are duly taken into account.     

Beliefs about child witnesses: A survey of professionals

This research addressed how professionals involved with the legal system evaluate children, primarily between 4 and 8 years old, as witnesses. In particular, we focused on professionals’ beliefs and opinions regarding children's memory, suggestibility, and behaviors as they relate to witness credibility. In addition, we surveyed professionals’ evaluations of investigative methods related to reliability. Four hundred and seventy-eight professionals working with children in the Norwegian legal system (i.e. judges, police detectives, psychologists, child psychiatrists, prosecutors, and defense attorneys) completed a questionnaire about child witness issues. Results indicated that psychiatrists as well as police officers expressed greater belief in children's capacities than did other groups, whereas defense attorneys and psychologists were more skeptical regarding children's general credibility. Psychiatrists and psychologists both, however, tended to favor, more than did legal professionals, the use of clinical techniques with children in abuse investigations. Implications are discussed in relation to professionals’ attitudes toward children as witnesses.     

A note on social drinking: In Vino Veritas

It has been a persistent phenomenon in many societies that a large proportion of alcohol consumption takes place in company of other people. While the phenomenon of social or public drinking is well discussed in disciplines such as social psychology and anthropology, economists have paid little attention to the social environment of alcohol consumption. This paper tries to close this gap and explains social drinking as a trust facilitating device. Since alcohol consumption tends to make some people (unwillingly) tell the truth, social drinking can eventually serve as a signaling device in social contact games.     

Managing technological distance in internal and external collaborations: absorptive capacity routines and social integration for innovation

While high technological distance to project partners outside of the established value chain can positively influence innovation performance, project goals can only be achieved if the social integration of project members is improved in terms of coordination and communication. This paper draws on embeddedness and absorptive capacity literature to explore how social integration mechanisms translate into different learning outcomes in distant collaborations within and across organizational boundaries. Drawing upon expert interviews with project members as our primary source of data, we conducted an in-depth multiple case study analysis of a number of inter-organizational projects. Our findings indicate that the effect of different types of social integration mechanisms on learning outcomes also affect the ability to bridge distances in process and product technology. Moreover, they suggest that it is not just the extent, but also the interplay of social integration mechanisms surrounding internal and external absorptive capacity routines that enable project members to engage in the exploration, transformation and exploitation of distant knowledge. In examining how social integration mechanisms foster learning outcome in distant collaborations, our study contributes to the literature on absorptive capacity.     

Norms in International Relations: Some Conceptual and Methodological Reflections

Acknowledging the social constructivist turn in the study of norms, this article offers to demonstrate that the notion of norms is useful as an analytical tool and likely to become a lasting element in international relations theory. Ideational causality and the independent explanatory power of norms are methodological issues that have been debated widely. Despite arguing that norms matter, social constructivism has problems making a successful case for the independent influence of norms. This article explores social constructivism as an approach to understanding international norms and their origins.
