Party identification traditionally is seen as an important linkage mechanism, connecting voters to the party system. Previous analyses have suggested that the level of party identity is in decline in Germany, and this article first expands previous observations with more recent data. These suggest that the erosion of party identity continues up to the present time. An age–period–cohort analysis of the panel data of the SOEP panel suggests that period effects are significantly negative. Furthermore, it can be observed that throughout the 1992–2009 observation period, education level and political interest have become more important determinants of party identity. Contrary to some of the literature, therefore, it can be shown that the loss of party identity is concentrated among groups with lower levels of political sophistication, indicating that the socio-economic profile of the group with a sense of party identification has become more distinct compared to the population as a whole. In the discussion, we investigate the theoretical and democratic consequences of this trend.  相似文献

This article explores the recent debate over the quality of Africa's growth episode of the past decade, specifically insofar as it pertains to the pitfalls of commodity-dependent growth and the hypothesised ‘resource curse’. In addition, the article focuses on why political and economic institutions are important, and why they are indicators for the likely development impacts of Africa's evident mineral and hydrocarbon wealth. Third, it suggests a useful theoretical framework for understanding these indicators, especially with regard to the differing constraints under which foreign investors operate and interact with host countries. Developing on the latter points, the article looks at the nature of Chinese foreign investment in Africa's extractive industries. Finally, the article suggests an agenda for future research that could better inform development policy for the purpose of promoting high-quality growth in Africa.  相似文献

Political sex scandals are largely absent in some democracies but proliferate in others. However, there have so far been few if any comprehensive attempts to document the actual number of sex scandals that have occurred and to explain their presence (and, indeed, absence), and the one study that has (Barker's 1994 study) ended in the early 1990s and had numerous problems in relation to defining and documenting such scandals. Based on extensive research, this article documents the number of sex scandals in eight advanced industrial democracies and tries to explain their occurrence using Charles Ragin's fuzzy set qualitative comparative analysis. The article has three goals: to determine the number of sex scandals in different democracies, explain why this might be, and demonstrate the utility of fuzzy set qualitative case analysis for small- and medium-N comparative research.  相似文献

Abstract: Larvae and pupae of blow fly species are frequently used in postmortem interval estimation, their age indicating minimum time since death. Most studies have considered age estimation of larvae, neglecting study of pupae. Relative development of external pupal features is useful, but there are also internal changes during metamorphosis that may be indicators of age, utilizing histological techniques. This study aimed to optimize preservation and histological analysis of blow fly pupae, specifically Calliphora vicina Robineau‐Desvoidy and Lucilia sericata (Meigen), and to examine internal features with potential for age estimation. Effect of hot‐water‐killing and different preservatives were examined. It was determined that blow fly pupae should be pierced through the three tagma, hot‐water‐killed, and preserved in 80% ethanol as the optimal preservation for subsequent analyses. Hematoxylin and eosin stained pupal sections revealed differences in brain and thoracic muscle development throughout the pupal stage with potential for age estimation.  相似文献

Traffic crashes kill 1.2 million people annually, and the number is growing fast, particularly in developing countries. Although child road-safety education is widely considered important, few programmes have resulted in demonstrated improvements in safety. We review road-safety education in Ethiopia and conclude that it is often locally inappropriate and impractical. Such programmes are frequently based on dominant but ineffective educational models imported from other contexts. Drawing on our experience of establishing a community-managed child road-safety education programme in Ethiopia, we suggest how road-safety education in developing countries might become more effective.  相似文献

The article demonstrates that the rigid use of veto capacity in coalitions causes risks for re-election. Justice was a high-salience domain of the German Liberal Democratic Party (FDP), which occupied this portfolio in its coalition with the Conservative majority in the federal legislative period from 2009 to 2013. By analysing several legislative projects the article shows that their contents or non-adoption were an effect of liberals' vetoes. This policy-seeking strategy provoked conflicts within the coalition and stalemate making it impossible to realise popular measures that would have enhanced the Liberals' reputation and the importance of the domain for the voters who were mainly interested in economic and social policy. Moreover, the Liberals' vetoes led to a loss of support from its major coalition partner in the pre-election campaign. Thus governmental parties have to trade off policy and vote-seeking goals in order to get re-elected.  相似文献

This article examines the relationship between fiscal year 1990 Fish and Wildlife Service spending on endangered species recovery and the priority ranking assigned by the Fish and Wildlife Service to particular species. The focus of the analysis is on the extent to which resources were allocated to species assigned higher priority rankings. The major conclusions are: species' recovery priority rank is not related to funding decisions by the Fish and Wildlife Service; some of the individual factors that make up the overall priority ranking—recovery potential and conflict with development—are correlated to funding decisions; and the likelihood of receiving some Fish and Wildlife Service recovery funding was greater for mammals, birds, and fish.  相似文献
