We examine the gender gap in turnout in Switzerland by analysing the 2003 federal elections. Despite being a standard component in electoral studies, the gender variable is, in most cases, only used as a control variable and its effects and interaction are too often under‐analysed. We focus on individual‐level factors by looking at three types of explanations for the gender gap: (1) resources, (2) political motivations and attitudes, and (3) social capital and integration. Our analysis, based on binomial logistic regression models, shows that compositional and conditional effects play an important role in explaining the persistent gender gap in Swiss electoral turnout.  相似文献

The problem of the time distribution of suicide has aroused the interest of many authors, but their findings often appear uncertain and contradictory. These inconsistencies can be partially explained by both the choice of the sample and the statistical method used for the analysis. In this study, in order to reveal expected and unexpected periodicities in the time distribution of suicides, we analyzed a small but complete and very homogeneous sample of suicides which occurred in the Mountain District of the Metauro River Valley in Italy in the period 1960-1994. A recent circular statistics technique, the "maximization of mean vector length" was used. We found no significant weekly and lunar patterns, but significant seasonal and intraseasonal cycles, with peaks in March and at the beginning of each season. The superposition of these two significant cyclic trends was also studied.  相似文献

Eight cases that occurred indoors in which the insects played an important role in the mPMI estimation are presented. The bodies of socially isolated people and old people living alone were discovered in central Italy between June and November. mPMI ranged from a few days to several weeks. Insects were collected during the body recovery and the postmortem. Climatic data were obtained from the closest meteorological stations and from measurements performed on the site. Sarcophagidae and Calliphoridae species were present in 75% of the cases with Lucilia sericata and Chrysomya albiceps collected in 50% of the cases. Chrysomya albiceps was always found in association with Lucilia species. Scuttle flies (Phoridae) were found in 37.5% of the cases, confirming the ability of these species in indoor body colonization. We show that if sealed environment may delay, the insect arrival dirty houses may create the environment where sarcosaprophagous insects are already present.  相似文献

The Ukraine crisis and subsequent tensions in relations with Russia urged the European Union to diversify its energy suppliers and integrate the energy markets of member states. However, the EU does not seem to have a clear strategy to strengthen its energy security. Member states are reluctant to relinquish control over their energy policy. Moreover, the diversification of fossil fuel suppliers may lead to new dependencies on authoritarian states, while the emphasis on unconventional energy sources may delay the development of renewables. A coordinated focus on renewable energy, coupled with investments in energy efficiency, appears to be the most forward-looking and climate-friendly way of reducing external dependencies.  相似文献

In the Western world, self-incineration is a rare event compared with the Asian countries. The circumstances of death are often unusual, and differentiation from homicide is sometimes possible only after evaluating all the investigation results and findings. In many cases of self-cremation, a fire accelerant is used. In our study material at least 30% of the body surface were burned. Unaffected skin was predominantly found on the back of the body. The cases presented by us are inhomogenous as to the motive and differ from those reported in the literature with regard to gender distribution, scene, motivational situation and psychological constitution.  相似文献

This pilot study provides a conceptual framework for the application of the anthropological analysis of skeletal features and surgical interventions for the purpose of identification in cases of unknown deceased individuals with unavailable fingerprint, genetic or odontological antemortem data. The study sample includes 276 individuals with known demographic and clinical information from the Italian CAL Milano Cemetery Skeletal Collection. In the sample, 124 (45%) individuals showed one or more skeletal features that may be potentially individualizing. Of these, 79% showed two and more features, which occurred in a multitude of different combinations. Skeletal findings may provide useful postmortem information that can be compared with antemortem witness statements and clinical imaging. However, more research into the utility of dry bone findings and the availability of comparative material, including imaging, and epidemiological data needs to be undertaken before skeletal features can be implemented into identification protocols and databases.  相似文献

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
