Abstract In several recent studies George Rabinowitz and his co–authors challenge the 'classical' spatial model of issue voting, the proximity model, by introducing a directional model. In this article we examine whether different measurement of perceived issue positions of candidates or parties leads to diverging judgments about the predictive power of the directional model (which is claimed to be empirically superior), as compared to the proximity model, using data from the USA and Germany. The results demonstrate that the measurement preferred by Rabinowitz et al. tends to bias empirical findings in favour of directional theory. If we use a more plausible operational definition of issue positions of candidates and parties the directional model in both countries fails to turn out superior. 相似文献

Although there have been several studies of women in legislatures in Canada, a cabinet position is a much stronger position from which to wield power in an executive-centered and party-disciplined parliamentary system. In the past decade, the increase of women's share of legislative seats, for majority parties as well as others, has led to more women being appointed to cabinet portfolios. This article utilizes data from the ten Canadian provinces over an 18-year period, from 1976 to 1994, to assess patterns of such appointments by province, party, percentage of women in the governing party, and percentage of women in the legislature. The proportion of women in the governing party far outweighs other variables in its impact on the percentage of women in the cabinet, in contrast to a previous study of West European cabinets which found that more women in the legislature was of greater importance. Although a high level of multicollinearity indicates caution in attempting to distinguish between the impact of these two variables, the differences in these studies may be due to Canadian provinces having single-party majority governments while West European cabinets are often coalitions. 相似文献

To construct and validate an instrument that would measure barriers to help-seeking behavior in adolescents. Method: A 37-item questionnaire based on prior help-seeking literature was constructed to yield a total score indicating strength of barriers to help-seeking behavior. The instrument was given to a sample of 280 high school students following a pilot study of 65 students. Results: The instrument was found to have good test–retest and internal reliability and adequate validity in the tested population. It shows promise in helping to identify adolescents who may be amenable to, and opposed to, therapeutic intervention, and may aid in understanding which barriers to help seeking are most significant in any given population. 相似文献

Drawing on a purposive sample of 25 interviews supplemented by secondary source material, this comparative study explores the options available to elderly immigrants in two quite similar countries to achieve social security in their old age. The focus is the culturally determined perspectives and practices of aging Italian-born and Indian-born immigrants in the context of public and private sector social welfare policies and provisions in Australia and Canada. Government transfers, occupational superannuation, tax-deductible personal savings, housing, and formal and informal supports are discussed. What is important to the sense of social security of the older people and how well-off or disadvantaged they seem to be are among the questions raised. The design affords an opportunity to test the complex combination of cross-national and cross-cultural comparison. In the certainty that the income deficiencies of today's elderly immigrants cannot be remedied easily or quickly enough to benefit those affected, intervention strategies can be aimed at expanding ethno-specific community supports and quality residential care; such a direction is supported by assessment of service availability in relation to estimates of aging among particular foreign-born immigrant groups. Suggestions are made for future research at the levels of theory and application. 相似文献

In this paper a new economic approach to standardization has been presented. Standardization has been regarded as a problem ofgradual choice. An individual chooses to apply more or less standards within a hierarchy of standards. With this decomposition of standards, the problem of strategic market power becomes less important than in the traditional models of standardization. It becomes possible to analyze the problems of network externalities within a framework of non-strategic behavior and to apply the tools of the traditional theory of externalities and public goods. While decentralized action may lead to too little standardization, committees may overcome this deficiency to some extent, but bureaucracies are likely to lead to overstandardization. In the empirical section of the paper it has been shown that our approach can be applied to the standard-setting process in languages, railroads, and telecommunications. In all three cases the tendency of bureaucracies to generate more standardization than committees has been corroborated.The authors are indebted for helpful comments to the participants of the Berlin Seminar on Political Economy and of the colloquium Algemene Economie, Rijksuniversiteit Groningen, and to A.

Intention des Beitrages ist es, Geschlecht und Familie auf der Basis eines institutionenorientierten Lebenslaufansatzes neu zu durchdenken. Die Zentrierung auf gesellschaftliche Institutionen als Orte der Vermittlung von individuellem Handeln und sozialstrukturellen Bedingungen ermöglicht es, mikro-, meso- und makrosoziale Interdependenzen in den Mittelpunkt zu rücken und bisher zum großen Teil verdeckten, da indirekten Strukturierungen von Geschlechterverhältnissen auf die Spur zu kommen. Aus dieser Perspektive relativiert sich die in der Lebenslaufforschung dominierende Individualisierungs-These zugunsten der Erkenntnis, dass Individuen sich durch institutionelle Eigenlogiken untereinander vernetzt sehen, die sie in neue Zwickmühlen bringen. Der Beitrag von Lebenslauf-Institutionen zur Rekonstruktion einer Geschlechterordnung gerät zwar zunehmend in Widerspruch zu Anforderungen an das individuelle Management der eigenen Biographie, doch der relationale Bezug zwischen Institutionen scheint Familie und Geschlecht weder aus ihren subjektiven Verpflichtungsmustern zu entlassen, noch aus ihrer sozialstrukturellen Vermittlerrolle zwischen biographischen Optionen und inkompatiblen institutionellen Verfügbarkeits-Ansprüchen. 相似文献

2016 coroner's crematorial inquests of the Bonn Institute of Legal Medicine over a 3 years' period were evaluated and the statements in the death certificates were compared to those ones of the Statistical Country Office of Northrhine-Westphalia. No significant differences were found with respect to age, gender and reason of death. However, the number of insufficiently classified deaths with respect to the reason of death were overrepresented especially in cases of older women, while the number of unnatural deaths was generally underrepresented. According to legal medical criteria 2 1/4 per cent of the deaths were falsely classified as natural. Only in 2 cases an autopsy was accomplished. Other author's statements on the validity of death certificates were confirmed. 相似文献

After surgical treatment of an inguinal hernia, a 26-year-old male was discharged from hospital with a well healing surgical wound. Four weeks later he was admitted again with a major localized painful swelling of the soft tissues, whereas the clinical examination revealed no further local or systemic signs of inflammation. The immediate operation disclosed no abscess formation, but a large colliquation necrosis of the subcutaneous tissue with an outstanding petroleum-like odour. On toxicological examination of the necrotic tissue, a respective petroleum distillate was found. The patient was confronted with the suspicion of having injected the petroleum preparation himself to prolong the wound healing and finally admitted the self-mutilating behaviour. The pathophysiology, clinical history and morphological findings are discussed in comparison with case reports of chemically induced self-mutilation. 相似文献
