The estimation problem of the parameters of a mixed geometric lifetime model, using Bayesian approach and Type I group censored sample, will be investigated in the case of two subpopulations. The Bayes estimates are derived for squared error, minimum expected, general entropy and linex loss functions under informative and diffuse priors. A practical example given by Nelson (W.B. Nelson, Hazard plotting methods for analysis of the life data with different failure models, J. Qual. Technol. 2 (1970), pp. 126–149) is considered. A simulation study is carried out along with risk. 相似文献
Previous research reveals that the characteristics and practices of a child's family are important determinants of its chances of surviving beyond childhood. This study investigates the effects of consanguinity on a family's odds of experiencing the death of a child in Pakistan, a society in which marriage among close relatives is common. Analysis of data from the 1991 Pakistan Demographic and Health Survey reveals that first cousin marriages increase a couple's risk of enduring the death of one or more of their children. These couples are 1.18 times as likely to have a child die by its fifth birthday than couples not related by blood net of other factors associated with child mortality. Elimination of first cousin marriages would contribute to a modest decrease in the proportion of Pakistani families suffering the death of a child. 相似文献
In an era of globalization, multifaceted and complex changes have increasingly interconnected geographically dispersed places. A central question of globalization studies concerns whether top-down forces of globalization are forging a global culture or whether processes of globalization from below are able to push back against homogenization by appropriating global forces rather than simply being overwhelmed by them. In this paper, I develop the concept of intentional spaces to show how ideas move globally and how local communities appropriate these ideas, revealing the actual practices that happen in the middle of top-down and bottom-up processes of globalization. I identify three types of ‘intentional spaces’ – physical, pedagogical, and ideological – to document the middle: where top down global forces meet local responses, and how these processes unfold. These intentional spaces enable processes of globalization from below, particularly the development of a mode of critical education that is both political and anti-hegemonic. This critical education empowers local people to adapt global/Western perspectives and influences to indigenous perspectives and practices, creating its own discourses of globalization. I use the context of the trans-Himalayan region of Ladakh to consider how national and international forces intersect with the local, and how local communities re-envision their participation in a modern, global economy. 相似文献
The author examines trends in the roles of immigrant Asian women workers in Kuwait, using data from published censuses and reports and from three national-level surveys conducted in 1977-1979, 1983, and 1986-1987. "The study deals separately with the two major types of migrants: the domestic servants and the clerical and professional (or semiprofessional) workers.... The policies of sending countries and of Kuwait are discussed to reach some conclusions about the likely future patterns of migration of Asian women workers to Kuwait." 相似文献
This article is an attempt to generalize some of the recent papers on randomized response techniques by using the negative binomial distribution of order k to randomize the responses in the randomization design where respondents can report outcome of one of two binary devices depending upon their actual status. The relative efficiency results are observed to be better than those of many recent and relevant randomized response techniques. The results are also better than those of the base line model used in this study, providing the sensitive attribute is rare. An extra advantage of the proposed technique is that it does not require any additional sampling and administrative cost. 相似文献

Mass migration is increasing urban populations globally. One country where urban migration is significantly increasing is Bangladesh, where systematic research will explore the reasons for urban migration in order to devise policies in this area, including maintaining the balance of urban–rural developments. This study used the Urban Health Survey (UHS) 2013 to ascertain the reasons for urban migration in large divisional cities in Bangladesh. The 2013 survey examined the differences between male and female migration, alongside any significant sociodemographic factors that might contribute to their motivation for moving to the city. The survey revealed that a majority of women (64.8%) migrated for family purposes, for example, joining husbands or in-laws, or parents/children. However, in recent years, female migrants have been involved in income-generating activities mostly due to a recent garment-making boom in Dhaka and its suburbs. A higher proportion of men (85.3%) moved to urban areas for work-related reasons: searching for new jobs, better income, or transfer in services. Among the sample in this study, 77% of the respondents (79.3% female and 73.5% male) migrated from villages. This migration mostly centered on Dhaka, the capital city of Bangladesh, where 68.1% of the total study sample migrated followed by 15.7% who went to Chittagong. The results indicate that the contemporary urban-centered economic policy in Bangladesh might require revision to accommodate the increased migrants from rural areas.
AbstractIn this article, we propose a two folded approach for estimation of the population proportion of a sensitive attribute. The rationale of proposed technique is to give respondents choice if they want to avail randomized device or not. Thus, our technique is inherently capable of entertaining the responses attained through direct questioning and by employing randomization device, as well. We believe that free to choose policy will be helpful to develop a curtsy between interviewer and respondent (which is highly desirable, especially when sensitive issue is under consideration) and thus enhances the survey reliability. The proposed technique is developed for simple random sampling, at first, and then extended to stratified random sampling. The superior performance of proposed technique in comparison to the Kuk (1990Kuk, A. Y. 1990. Asking sensitive questions indirectly. Biometrika 77 (2):436–8. doi:10.1093/biomet/77.2.436.[Crossref], [Web of Science ®], [Google Scholar]) method is demonstrated throughout this article. We provide algebraic, graphical and numerical evidences in support of our proposed technique. Furthermore, we also offer cost analysis considering most commonly used cost functions in the literature of survey research. 相似文献
