A survey was conducted of approximately 200 Asian Indian Americans and 200 other residents of New Jersey in order to understand the risk management priorities that they want government to have. We found that Asian Indian Americans, especially younger women, focused on personal/family risks, such as alcohol and drug abuse, sexual abuse, and domestic violence. The New Jersey comparison group, in contrast, placed war/terrorism and loss of health care services and insurance at the top of their priorities for government. These results suggest stressful acculturation-related issues within the Asian Indian community. Both populations want more risk management from government than they believe government is currently providing. Respondents who wanted more from government tended to dread the risk, be fearful of the consequences, trust government, and have a feeling of personal efficacy. Within the Asian Indian American sample, wide variations were observed by language spoken at home and religious affiliation. Notably, Muslims and Hindi language speakers tended not to trust government and hence wanted less government involvement. This study supports our call for studies of recent migrant populations and Johnson's for testing ethnic identity and acculturation as factors in risk judgments.  相似文献

The paper considers simultaneous estimation of finite population means for several strata. A model-based approach is taken, where the covariates in the super-population model are subject to measurement errors. Empirical Bayes (EB) estimators of the strata means are developed and an asymptotic expression for the MSE of the EB estimators is provided. It is shown that the proposed EB estimators are “first order optimal” in the sense of Robbins [1956. An empirical Bayes approach to statistics. In: Proceedings of the Third Berkeley Symposium on Mathematical Statistics and Probability, vol. 1, University of California Press, Berkeley, pp. 157–164], while the regular EB estimators which ignore the measurement error are not.  相似文献

In regression analysis, it is assumed that the response (or dependent variable) distribution is Normal, and errors are homoscedastic and uncorrelated. However, in practice, these assumptions are rarely satisfied by a real data set. To stabilize the heteroscedastic response variance, generally, log-transformation is suggested. Consequently, the response variable distribution approaches nearer to the Normal distribution. As a result, the model fit of the data is improved. Practically, a proper (seems to be suitable) transformation may not always stabilize the variance, and the response distribution may not reduce to Normal distribution. The present article assumes that the response distribution is log-normal with compound autocorrelated errors. Under these situations, estimation and testing of hypotheses regarding regression parameters have been derived. From a set of reduced data, we have derived the best linear unbiased estimators of all the regression coefficients, except the intercept which is often unimportant in practice. Unknown correlation parameters have been estimated. In this connection, we have derived a test rule for testing any set of linear hypotheses of the unknown regression coefficients. In addition, we have developed the confidence ellipsoids of a set of estimable functions of regression coefficients. For the fitted regression equation, an index of fit has been proposed. A simulated study illustrates the results derived in this report.  相似文献

The study uses an eclectic framework and through an intersectional analysis and use of narratives explores the meaning of janitorial work, the gender division of labour (GDL), the unions and organizing for janitors engaged in industrial cleaning for a big cleaning company, Pluto, in Toronto. Pluto was organized by the Service Employees International Union (SEIU) in 2006. The study is based on the organizing drive for Pluto and uses participant observation and interview methods. Intersectional analysis is useful in understanding the worker's perceptions of the racialized, gendered and classed constitution of cleaning work as ‘dirty’ and their resistance to these constructs. We explore GDL in industrial cleaning and the construction of women's work as ‘light duty’ and men's work as ‘heavy duty’. We conclude that union membership is important not only for material benefits of the janitors but also for their alternative identity construction. However, there is a persistence of GDL and gender pay equity is not addressed seriously in the organizing drive or upon organizing.  相似文献

This paper provides a partial solution to a problem posed by J. Neyman (1965) regarding the characterization of multivariate negative binomial distribution based on the properties of regression. It is shown that some of the properties of regression characterize the form of the nonsingular dispersion matrix of the parent distribution, which, interestingly enough, corresponds to only two types viz. those of positive and negative multivariate binomial distributions.  相似文献

Population aging in Nepal is a recent phenomenon, due more to demographic changes than to socio-economic development. The study had three goals: to analyze the social support exchange among elderly men and women; to discover the main sources of support in loneliness and subjective well-being in the elderly; and to study the cross-cultural differences in support among elderly Chhetri ( N  = 137, mean age = 69.1 [7.2] years) and Newar people ( N  = 195, mean age = 68.8 [7.7] years) in one ward in Kathmandu. The data were collected using face-to-face interviews. The dependent variables were loneliness and subjective well-being (SWB). The results for both ethnic Chhetri and Newar respondents show that their major support comes from their children living in the same household and their spouses. I conclude that the sources of social support and social support exchange are similar between the two castes/ethnicities and that there are no cross-cultural differences between them in terms of support for loneliness and SWB-life stability, although there are cross-cultural differences in their SWB-life satisfaction. Providing social support to friends and neighbors appears to be related to less loneliness and increased SWB in both castes/ethnicities.  相似文献

Abstract

In the spring of 2003 the University Libraries at University of Nevada, Las Vegas (UNLV), conducted a Serials Assessment Project which combined technology with effective communication between library users and subject librarians to successfully identify journals that could be cancelled, should cancellations be necessary due to budgetary constraints. Although the library had conducted similar assessments in 1998 and 2000, a fresh look at past assessments resulted in an innovative approach. The project and experience proved to be tremendously positive for both the library and its users. This article describes the planning and process by which the UNLV libraries designed and conducted the 2003 review of UNLV's serials collection, comparing it to methods used in the two previous assessments.  相似文献
