In the article, properties of the Bennett test and Miller test are analyzed. Assuming that the sample size is the same for each sample and considering the null hypothesis that the coefficients of variation for k populations are equal against the hypothesis that k ? 1 coefficients of variation are the same but differ from the coefficient of variation for the kth population, the empirical significance level and the power of the test are studied. Moreover, the dependence of the test statistic and the power of the test on the ratio of coefficients of variation are considered. The analyses are performed on simulated data. 相似文献

The multiple non symmetric correspondence analysis (MNSCA) is a useful technique for analyzing a two-way contingency table. In more complex cases, the predictor variables are more than one. In this paper, the MNSCA, along with the decomposition of the Gray–Williams Tau index, in main effects and interaction term, is used to analyze a contingency table with two predictor categorical variables and an ordinal response variable. The Multiple-Tau index is a measure of association that contains both main effects and interaction term. The main effects represent the change in the response variables due to the change in the level/categories of the predictor variables, considering the effects of their addition, while the interaction effect represents the combined effect of predictor categorical variables on the ordinal response variable. Moreover, for ordinal scale variables, we propose a further decomposition in order to check the existence of power components by using Emerson's orthogonal polynomials. 相似文献

The scientific literature stresses the importance of culture and social environment in determining what people think about alcohol consumption and consequently do. Several pieces of research have proved the influence on young adults’ alcohol use of proximal social contexts of their family and peers. The present study aimed at investigating the influence of family behaviours and norms compared to the peers’ influence in a context where the culture of alcohol is changing between the different generations. Data were collected by means of a self-report questionnaire on a sample of 598 young adults (average age 22.20 years). The variables investigated were socio-demographic characteristics, the alcohol consumption of parents and friends and the parents’ and peers’ approval of alcohol consumption. The results confirmed the role of family and friends in influencing young adults’ consumption of alcohol, stressing a difference between perceived behaviours and norms. The perceived consumption of parents and friends influenced the participants’ consumption. On the contrary, the effects of the approval of drinking were limited. Globally friends had a stronger influence on alcohol consumption in comparison with family. 相似文献

Research on domestically violent men typically takes an oppositional logic of gender. While the significance of class in researching domestically violent men is identified, class and gender are often treated as separate entities that do not complicate each other. Drawing upon group observations and in‐depth interviews, this paper identifies how intersections of class and gender manifest in the counselling experiences of domestically violent Taiwanese men. From a Bourdieusian feminist analysis, the authors analyse (1) how class distinctions serve to (re)produce gendered hierarchy; (2) how contradictory experiences of gender reveal a relational understanding of class; and (3) how the gendered nature of domestically violent men is inscribed with a meaning of (working) class specificity for maintaining middle‐class ‘purity’. In analysing men's multiple and conflicting experiences, this paper contributes to research on domestically violent men by showing how class and gender are actively constructed and not produced in a monolithic/invariant way. 相似文献

This article focuses on family involvement and its various patterns and expressions in the context of end-of-life care in a nursing home. Based on analyses from an ethnographic study carried out at a nursing home ward, the aim is to describe and analyze the conditions of aging and dying for the old residents, as well as effects on their visiting families and relatives. As in similar research findings, it became clear from the study that families continue to visit and contribute to the care of the old resident throughout the years, from the time of placement to their demise, but that this involvement might vary both in content and in extent. However, it was found that families' involvement (as well as their changing relationships and roles) is particularly shaped by the very process of dying and lingering aura of death on the ward. The analysis presented in the article evinces the difficult — and in many ways impossible — role of the family in the institutional end-of-life setting, and discloses the various patterns and manifestations of family involvement in this environment. Different meanings and implications of family involvement are discussed and highlighted. 相似文献

Drawing on interviews with parents of children with complex disabilities in several school systems in a US state, this paper examines how temporal units such as the school day and school year and practices organized around artifacts like clocks and calendars work as ‘devices of temporal distanciation’ to separate children with disabilities from other children and exclude their families from critical relations with schools. The paper focuses on two kinds of effects: the ways differentiated timetables separate children and the ways constructing school time in bounded, discrete units limits the ability of parents and children to make key elements of their lives visible to the school. 相似文献

Self‐reported attachment styles with mother, father, best friend, and romantic partner were assessed longitudinally across adolescence. Three cohorts (ages 13, 16, and 19 years; N=373) from a community sample were followed across 2 years. There was only one change in attachment styles with age: the oldest adolescents were more dismissive than the younger. Adolescents were more secure with mother than with father, and most dismissive and fearful with father. Boys were more dismissing than girls, who were more fearful with a romantic partner (n=158). Across time, attachment insecurity with father was associated with insecurity with a best friend. Attachment insecurity with a romantic partner was associated primarily with insecurity with friend, but changes over time tended to be associated with insecurity with mother. Results support the view of a differentiated hierarchy of attachment figures in adolescence, with the quality of parental attachment contributing to close extra‐familial relationships. 相似文献

During the modern phase of economic reforms directed at the establishment of market economy, many countries with transition
economies face the challenge of solving the issue of formation and rational usage of internal sources of financing the real
sector of the economy, as well as attracting considerable volume of direct foreign investment. In general, financial market
imperfections hold back innovation and growth, and that public policy can complement financial markets. Therefore, the most
relevant issue at the present time is the formation of attendant and complex supervision institutions, as well as an exigency
of innovative economy governance as mainframe principles for further banking system elaboration and financial sector development
in general. We have taken Armenia as a case study for transition economy as far as Armenia is currently in the stage of capital
market development through integration into international financial markets.
