In non‐presidential multiparty systems, it is not only the voters but also coalition formation after the election that decides the government of the community. Some national‐level studies investigate which parties are most likely to win the Prime Minister's office. The aim of this article is to investigate the same question at the local level: What makes a party more likely to win the post of mayor? The article finds that party size and change in size are important along with experience and ideological centrality. The results are similar to those obtained at the national level, and this study thus expands the scope of these explanatory variables. However, the study also shows that being a large party is not sufficient for a party to have a good chance of winning the mayoralty. Furthermore, norms guiding appropriate behaviour seem important in addition to instrumental behaviour. It appears that parties that are popular in the electorate benefit from being perceived as more deserving of the mayoralty than others.  相似文献

The introduction of mandatory gender quotas in party lists is a reform that many countries have recently adopted or have been considering. The electoral system affects the incumbents' incentives to make such reforms, their details, and their effectiveness. We show that male incumbents can actually expect an increased incumbency advantage when gender quotas are introduced, if they are elected through single‐member district majority rule. On the other hand, no expectation of male advantage can reduce the incumbents' fear of being replaced if they are elected through closed‐list proportional representation. As France has both electoral systems, we validate the above argument using a formal model of constitutional design as well as an empirical analysis of the legislative elections in France, displaying the existence of male bias in the last three elections. We also show that parity may have Assembly composition effects and policy effects that vary with the electoral system.  相似文献

This article considers wage?–?labour activities by agricultural households in Nicaragua. It analyses the role of: (1) comparative advantage as determined by individual and household characteristics; and (2) agricultural conditions and market imperfections, in shaping wage?–?labour supply. An econometric specification is developed which allows for random household-specific effects. Results reveal that non-agricultural wage work is largely determined by comparative advantages, whereas agricultural wage work is used to deal with a number of agricultural conditions and market imperfections.  相似文献

Government coalitions should be minimal winning. However, it is an empirical fact that oversized coalitions exist. Several theories have been offered to explain this phenomenon, but they are seldom put to a systematic empirical test. When empirical tests are performed, they are typically based on data on national government formations in post-war Europe. Since these are the data that gave rise to the theories in the first place, there is a risk of post hoc hypothesis reformulation. The purpose of this paper is to test explanations of oversized coalitions systematically in a new empirical setting and thus avoid this circularity problem. We focus on local governments in Denmark and have collected data by a survey sent to almost 3,000 local councillors. We draw hypotheses from three broad theoretical perspectives on oversized coalitions and test them in a logit regression analysis. The analysis shows that oversized coalitions cannot be explained by traditional coalition theories. Our results question the minimalist behavioural logic inherent in most coalition theories and suggest that parties may be motivated by norms.  相似文献

Objectives

The Norwegian Mental Health Care Act allows use of coercion under certain conditions. Even though the current practice has been criticized, little empirical data exist about the attitudes towards compulsory mental health care.

Method

This study used Q-methodology to identify prototypical attitudes and to test possible differences of attitudes between groups of stakeholders towards the use of coercion in mental health care. Sixty-two respondents who represented six groups with different roles in mental health care participated: former patients, relatives of psychiatric patients, members of supervisory commissions, psychiatrists, other physicians, and lawyers.The participants were asked to assess the degree to which they agreed on 30 statements concerning use of coercion for the mentally ill.

Results

Three factors that in a meaningful way express different attitudes towards the question were found. The most widely shared attitude stated that a trusting relationship between patient and therapist is more important than the right to have an attorney. This attitude gives partial support to the present Mental Health Care Act. However, the second most common attitude argues that involuntary hospitalization, if necessary, should be decided in a court and not by the hospital doctor.

Conclusions

Differences in attitude could partly be explained by the respondents' role in mental health care. Both psychiatrists and “somatic” physicians expressed more agreement with the present legislation than the other stakeholders. The findings may have implications for the legal protection of mental health care patients.  相似文献

Traditional forensic methods that highlight the spatial distribution of properties such as blood and fingerprints have two main disadvantages: they often apply chemicals that may influence further analyses, and they cannot easily be modified to search for new compounds/properties. A new instrument (called PryJector) avoids these problems by dynamically projecting back onto the surface under study spatially distributed information of compounds/properties (chemical images) obtained from multivariate analysis of hyperspectral images. Selectivity to target compounds/properties is ensured by multivariate modeling which makes the instrument much more flexible compared to traditional methods. The functionality of the PryJector is demonstrated in an application related to the detection of counterfeit pharmaceuticals where compounds otherwise indistinguishable to the human eye are made clearly visible by projection of false-colored chemical images. The PryJector is shown to be a noninvasive and very flexible instrument for highlighting spatial distributions of various compounds/properties.  相似文献
