A general form for characterizing inverse Gaussian and Wald distributions, based on their respective length-biased distributions, is introduced. Further results for characterizations of the gamma distribution, the negative binomial distribution and some mixtures of them by using their lengthbiased distributions are establised. 相似文献

The authors examine the effect of premarital cohabitation on the division of household labor in 22 countries. First, women do more routine housework than men in all countries. Second, married couples that cohabited before marriage have a more equal division of housework. Third, national cohabitation rates have equalizing effects on couples regardless of their own cohabitation experience. However, the influence of cohabitation rates is only observed in countries with higher levels of overall gender equality. The authors conclude that the trend toward increasing cohabitation may be part of a broader social trend toward a more egalitarian division of housework. 相似文献

This article illustrates how Uyghurs in the 1990s defined and reinforced contemporary Uyghur national identity in relation to Xinjiang's growing Han Chinese population. Adopting Barth's theory of fluid and negotiable ethnic boundaries, it focuses on the notion of change. While Uyghurs are currently activating and exaggerating certain religio-cultural differences--in particular the avoidance of pork--as a means of ensuring symbolic, spatial and social segregation from the Han, those criteria did not prevent interaction to the same extent in the past; nor do they prevent Uyghurs from making concessions when it benefits them to do so. It is argued that it is not religio-cultural differences per se that lie at the root of increased tensions between Uyghurs and Han Chinese, but changing social, political and economic contexts: on the one hand, growing Uyghur perceptions of socio-economic inequalities between themselves and the Han (the 'internal factor') and, on the other, the vast changes within the international political arena since the late 1980s (the 'external factor'). 相似文献

This article explores the effectiveness of self-defense training for college women. Advocates of self-defense training believe these courses will not only provide women with the physical survival techniques necessary to repel attacks effectively, but that this kind of training will also help to prevent future violence by developing traits such as assertiveness and confidence in individuals. There is evidence that women who convey such characteristics are less likely to be victimized. Opponents argue that self-defense training does not properly prepare women for an attack, does not adequately address acquaintance rape threats, and can provide a dangerous false sense of security to students. This article reviews the relevant literature, outlines practical suggestions for initiatives in this area, and describes a model self-defense course at one university. Guidelines for evaluation and implications for university policy and program decisions that address violence against women on college campuses are included. 相似文献

The small sample performance of least median of squares, reweighted least squares, least squares, least absolute deviations, and three partially adaptive estimators are compared using Monte Carlo simulations. Two data problems are addressed in the paper: (1) data generated from non-normal error distributions and (2) contaminated data. Breakdown plots are used to investigate the sensitivity of partially adaptive estimators to data contamination relative to RLS. One partially adaptive estimator performs especially well when the errors are skewed, while another partially adaptive estimator and RLS perform particularly well when the errors are extremely leptokur-totic. In comparison with RLS, partially adaptive estimators are only moderately effective in resisting data contamination; however, they outperform least squares and least absolute deviation estimators. 相似文献

In this paper, the notion of average total inspection (ATI) is introduced to ChSP-4(c1,c2) sampling plans. Procedures have been developed for the construction and selection of ChSP-4(c1, c2 plans, minimizing ATI at a given process average, while protection to the consumer is given in terms of the (i) average outgoing quality limit and (ii) limiting quality level.A wide range of c1 and c2 values are considered for developing tables which cover almost all practical situations. The procedure described is similar to that of Dodge and Romig. 相似文献

Bourdieu afflrme que le capital cultural est utile lorsque Ton veut obtenir une situation de classe supérieure, particuliérement dans certains secteurs, et n'est en fait qu'une seule chose: une culture de condition supérieure. Mais son argument, établit pour une France centralisée, est moins valable pour le Canada plus subdivisé. Cet article étudie les idées de Bourdieu sous tous leurs aspects pour un échantillon quota de Torontoniens. Les résultats suggèrent qu'un capital culturel de condition supérieure existe à Toronto, mais qu'il a peu d'effet sur les relations de classe au travail, ou le véritable capital culturel dirige la culture d'entreprise qui domine les entreprises privées. La culture d'entreprise est aussi repartie en classes et pourrait jouer un role dans la reproduction de classes qui est tres similaire a ce que Bourdieu revendique comme culture de condition supérieure.
Bourdieu argues that cultural capital is useful in gaining higher class location, especially in some sectors, and is essentially a single thing: high status culture. But his argument, developed for centralized France, is less suitable for more subdivided Canada. This paper explores Bourdieu's ideas through a quota sample of 40 Torontonians. Results suggest that high status cultural capital does exist in Toronto, but has little part in class relationships at work, where the true cultural capital is command of the business culture which dominates private enterprises. Business culture is also class stratified, and may play a role in class reproduction which is quite similar to that which Bourdieu asserts for high status culture. 相似文献

Using cluster analysis, 789 predominately Latino and African American high school youth were classified into varying academic at‐risk profiles using self‐reported levels of academic confidence, motivation to attend school, perceived family support, connections with teachers and peers, and exposure to violence. Six clusters emerged, 5 of which were identified as “at‐risk.” The clusters were examined in relation to academic stress, health status, grades, and school retention. Exposure to violence was one distinguishing feature of youth identified as most vulnerable, vulnerable, and resilient; however, youth identified as resilient recorded better academic outcomes. 相似文献

Peltzman [Peltzman, S., 1984. Constituent interest and congressional voting. Journal of Law and Economics 27, 181–210] argues that if constituents’ economic interests have well-defined “winners and losers” and are appropriately measured, then constituents’ economic interests, and not legislator ideology, are the most important determinates of legislator voting. We test Peltzman's theory by examining senatorial voting on three mandated spending limitation bills. We find, consistent with Peltzman's theory, that the ratio of federal spending in a senator's state to federal taxes paid by that state, and not a senator's personal ideology, matters on legislation where there are well-defined economic “winners and losers.” This is particularly important because unlike other constituents’ economic interest measures that only impact a fraction of the constituency, the ratio of federal spending to federal taxes in a state represents the economic interests of all the constituents in a state. 相似文献
