This article considers individual, communal, and cantonal sources of voting behavior in the 2007 National Council elections in Switzerland. Using hierarchical linear models, it is shown how the vote propensity for the five main parties (CVP, FDP, Greens, SP, and SVP) varies across individuals, communes, and cantons. Key explanatory factors at each of these levels are explored, as well as cross‐party differences in the effects of these factors. 相似文献

This article looks at the determinants of the political integration of migrants at the local level, focusing on two dimensions of political integration: political interest (attitudinal dimension) and political participation (behavioral dimension). Based on a representative survey among Italians, Kosovars, and Turks in the city of Zurich, we tested the thesis advanced by the social capital approach which posits a link between membership in voluntary associations and political integration. Our findings suggest that membership in voluntary associations favors the political integration of the three groups under investigation. Furthermore, we find an impact of both ethnic and cross‐ethnic membership. However, while the effect of associational involvement on the behavioral dimension of political integration is strong and consistent across national groups, the attitudinal dimension displays a weaker and differential impact. Political attitudes and socio‐demographic characteristics play a less important role, except for the effect of the former on political interest, and also tend to have a differential impact on the three groups. 相似文献

Crop genetic diversity and poverty are linked: first, resource-poor farmers often maintain genetic diversity; and second, crop diversity, when properly valued by the market, has the potential to alleviate poverty. This article examines this supposition by drawing on three case studies of the intersection of the market with poverty and maize diversity in Mexico. These suggest that the bulk market for maize offers little room for maize landraces (local maize varieties known as criollo maize), in that it does not reward qualitative variation in maize grain and instead presents incentives that make planting ‘improved’ maize germplasm the rational economic choice for small-scale farmers. Meanwhile, attempts to add value to maize landraces via market differentiation have had varying success. Although there is potential for differentiated markets to contribute to successful business models and poverty alleviation, these cases exhibit trade-offs between product consistency, investment of labour and resources, and genetic-diversity conservation. 相似文献

Item Similarity in Scale Analysis 总被引:1,自引:0,他引:1
A statisticthe similarity coefficientis developedfor assessing the property that a set of scale items measuresone and only one construct. This statistic is rooted in an explicitmeasurement model and is flexible enough to be used in exploratoryscale analyses, even in small samples. Methods for analyzingsimilarity coefficients are described and illustrated in analysesof Stimson's (1991) policy mood data and Markus' (1990) popularindividualism items. The Appendix discusses the statisticalproperties of similarity coefficients. 相似文献

Advanced technologies like nuclear power and looming environmental threats such as global climate change present major policy challenge for modern cultures. Public policy about such crucial and complex issues depends on public attitudes, which, in turn, tend to be strongly affected by mass media coverage. How “well” has the mass media portrayed these two evolving risk stories? Employing perspectives from both journalism and social science, this article will first review the history of mass media coverage of each topic, then analyze their differences. 相似文献
