This paper studies voting over quadratic taxation when incomeis fixed and taxation non distortionary. The set of feasibletaxes is compact and self-interested voters have cornerpreferences. We first show that, if a majority winning taxpolicy exists, it involves maximum progressivity. We then givea necessary and sufficient condition on the incomedistribution for a majority winner to exist. This conditionappears to be satisfied for a large class of distributionfunctions.  相似文献

The purpose of this research note is to examine if the attitude toward science of the Swiss citizens is related to their confidence in Swiss institutions, precisely in political institutions. Based on the results of one survey (Eurobarometer 2001), we show that the attitude toward science is moderately related to the confidence, that the number of significant relationship of each institution depend on the level of confidence of the institution, and that we distinguish two types of relation: linear and inverted U‐shaped.  相似文献

This paper analyzes marriage and divorce reform and family planning policies in the People's Republic of China in the context of the state-defined collective interest. A theoretical examination of the contradictions between women's liberation and the Marxist defined economic and political concerns of the state shows that liberation cannot be achieved until the state acknowledges the values of social reproduction and family nurturance. The empirical discussion of recent reforms in family policies in China points to the continuing manipulation of women's interests by the state. The tendency of the PRC government to make policy based on narrow economic considerations results in the maintenance of a system in which women's special interests are exclude from the collective interest and thus denied legitimacy.  相似文献

The interactions between Central and Eastern European (CEE) business interest associations (BIAs) and their EU trade associations have not yet attracted much attention in academic research. This paper has two main objectives. The first is to assess quantitatively the participation level of CEE BIAs in EU trade associations. The second is to assess qualitatively the nature of the relationships between them by surveying Bulgarian BIAs as a case study. This article stresses the fact that EU enlargement has decreased the representativeness of EU trade associations due to the weak level of membership of CEE BIAs. It also highlights the importance of membership in EU trade associations in terms of both Europeanization and socialization, even though CEE national BIAs, such as Bulgarian ones, are still very much anchored in their domestic interactions and lobbying.  相似文献

The dead body of a 44-year-old woman, previously known for depression and alcoholism, has been discovered at her place of residence by her husband. A forensic autopsy has been carried out. The results indicated unspecific histological lesions (alveolar oedema, liver steatosis and interstitial nephritis) but did not reveal any apparent cause of death. Several boxes of medicines have been found near the body, justifying a toxicological analysis. This has been performed on peripheral blood and urine samples using liquid chromatography with diode array and mass spectrometric detections, in conjunction with gas chromatography coupled with mass spectrometry. Ethanol has been found (1.24 g/L in blood, 2.63 g/L in urine and 1.33 g/kg in gastric content), as well as therapeutic concentrations of meprobamate (14.1mg/L) and low concentrations of nordazepam (0.12 mg/L) in blood. On the other hand, particularly high levels of labetalol, a widely used beta-blocker, have been found both in blood (1.7 mg/L) and urine (20.2mg/L), which led us to measure labetalol levels in available viscera samples (liver, heart, kidney, and lung) and gastric content. Measured concentrations were 14.2 microg/g, 7.8 microg/g, 5.4 microg/g, 5.2 microg/g and 31.1 microg/g, respectively. We describe here the first report of a fatal intoxication attributed to labetalol that is linked to its acute toxicity, with tissue distribution of this beta-blocker.  相似文献

The amount of empirical research on men who commit sexual murders is scarce, and no distinction has been made between those who have victimized adults and those who have victimized children. Therefore, to better understand specifically sexual murderers of children (n = 11), comparisons were performed with a group of sexual murderers of adult women (n = 66) on developmental, precrime, crime, and postcrime factors. It appears that sexual murderers of children are more often victims of sexual abuse during childhood and present more often deviant sexual fantasies as compared to sexual murderers of women. The results show also that sexual murderers of children more often use pornography prior to crime, have contact with the victim prior to crime, and commit a crime more often characterized by premeditation, strangulation, the hiding of the body, and its dismemberment than the sexual murderers of women.  相似文献

This paper focuses on shifts in the age distribution of homicide offending in the United States. This distribution remained remarkably stable with small but significant changes over a long period of time. Then between 1985 and 1990 the rates of homicide offending doubled for 15-to-19 year olds and increased nearly 40% for 20-to-24 year olds, while the homicide offending rates decreased for those over 30. In addition to this “epidemic of youth homicide,” which lasted through the mid-1990s, there have been systematic changes in the age distribution of homicide in the United States associated with cohort replacement over the past 40 years. We introduce an estimable function approach for estimating the effects of age, period, and cohort. The method allows us to assess simultaneously the impacts of periods and cohorts on the age distribution of homicide offending. We find that although the age curve remains relatively stable, there are shifts in it associated systematically with cohort replacement. Cohort replacement accounts for nearly half of the upturn in youth homicides during the epidemic of youth homicides, but a significant fraction of that upturn is not associated with cohort replacement.
