Logarithmic general error distribution, an extension of the log-normal distribution, is proposed. Some interesting properties of the log GED are derived. These properties are applied to establish the asymptotic behavior of the ratio of probability densities and the ratio of the tails of the logarithmic general error and log-normal distributions, and to derive the asymptotic distribution of the partial maximum of an independent and identically distributed sequence obeying the log GED. 相似文献

In this paper, locally D-optimal saturated designs for a logistic model with one and two continuous input variables have been constructed by modifying the famous Fedorov exchange algorithm. A saturated design not only ensures the minimum number of runs in the design but also simplifies the row exchange computation. The basic idea is to exchange a design point with a point from the design space. The algorithm performs the best row exchange between design points and points form a candidate set representing the design space. Naturally, the resultant designs depend on the candidate set. For gain in precision, intuitively a candidate set with a larger number of points and the low discrepancy is desirable, but it increases the computational cost. Apart from the modification in row exchange computation, we propose implementing the algorithm in two stages. Initially, construct a design with a candidate set of affordable size and then later generate a new candidate set around the points of design searched in the former stage. In order to validate the optimality of constructed designs, we have used the general equivalence theorem. Algorithms for the construction of optimal designs have been implemented by developing suitable codes in R. 相似文献

This study examines the contribution of the psychological contract (PC) framework to the understanding of ethnic minority employees’ employment relationships. First, it tests the generalizability of PC types (transactional, relational, and balanced) observed in the general population to ethnic minority employees. Then, to further address the unique needs and motivators of minority employees, this study considers diversity-related PCs. It adopts social exchange theory to explain how transactional, relational, balanced, and diversity-related PC breaches predict organizational citizenship behavior (OCB). Moreover, it draws insights from social identity theory and examines the mediating role of organizational identification in the relationship between types of PC breach and OCB. Data from 361 Turkish employees working as ethnic minorities in Belgium indicate that relational and diversity-related PC breaches predict OCB partially via organizational identification while transactional and balanced PC breaches directly affect OCB. 相似文献

Using longitudinal cohort studies from Australia and the United States, we assess the pervasiveness of the Asian academic advantage by documenting White-Asian differences in verbal development from early to middle childhood. In the United States, Asian children begin school with higher verbal scores than Whites, but their advantage erodes over time. The initial verbal advantage of Asian American children is partly due to their parent’s socioeconomic advantage and would have been larger had it not been for their mother’s English deficiency. In Australia, Asian children have lower verbal scores than Whites at age 4, but their scores grow a faster rate and converge towards those of Whites by age 8. The initial verbal disadvantage of Asian Australian children is partly due to their mother’s English deficiency and would have been larger had it not been for their Asian parent’s educational advantage. Asian Australian children’s verbal scores grow at a faster pace, in part, because of their parent’s educational advantage. 相似文献

The dual trajectories of Japanese sociology and Japan itself are poised at a watershed moment in their shared history. In recent years, Japanese sociology has enlarged its international presence in unprecedented fashion and the Tokyo Olympics have positioned the global spotlight on the entire nation of Japan, making it an opportune moment to reflect on the future of Japanese sociology in connection to Japanese society by way of internationalization. This article draws on the author's reflections on the latest 92nd Japan Sociological Society Annual Conference in the context of recent socio‐structural and intellectual transformations in counterpart sociological cultures in Anglo‐America. Drawing on three theorizations of disciplinary development by Abbott, Connell, and Burawoy, this article articulates two dimensions (socio‐structural and intellectual) with which to examine (i) what Japanese sociology can contribute to improve the internationalization decolonization, and pluralization of global sociology; and (ii) what global sociology can do to advance Japanese sociology's public contribution to improving and preserving LGBTQ minorities' societal well‐being. 相似文献

The tragic killing of George Floyd at the hands of the police resulted in hundreds of thousands of protestors marching in the streets demanding change. The call for change criticized the killing of Blacks by law enforcement and challenged White supremacy as an institution of social control and racial violence. A key component of the marches and protests was a message to the residents of the United States: “Black Lives Matter.” As society grapples with a reckoning, researchers studying police violence for the past 6 decades have been empirically and theoretically debating the reasons why use of force by law enforcement continues to have a higher proportion of Black and Brown victims compared to Whites. Although the research on fatal police killings was studied by only a small number of individuals prior to 2014, after the killing of Michael Brown in Ferguson, Missouri the research in different areas of the country increased rapidly as did the forms of analysis and research disciplines making their own contributions. The Washington Post and Guardian news agencies established that deaths at the hands of the police were occurring for at least 900 to 1100 individual deaths per year for which firearms resulted in the greatest cause of death. As US government agencies failed to produce a national data source on police involved killings, the media took a leading role in providing greater national understanding. The authors examine what role academic researchers contribute to the discussion for solutions, particularly those from marginalized backgrounds. As protestors march, lawyers sue and defend, and politicians create new forms of legislation, researchers need to play a more important role initiating critical studies, making sense of the data, and providing a theoretical framework for which police violence can be understood. This article will provide an overview of the literature on racialized police violence, point out key patterns involving racial and ethnic disparities, and emphasize how researchers can play a more important role in advocating for change. 相似文献

ABSTRACTDiscrimination against sexual minorities is widespread and has deleterious consequences on victims’ psychological and physical wellbeing. However, a review of the psychometric properties of instruments measuring lesbian, gay, and bisexual (LGB) discrimination has not been conducted. The results of this review, which involved evaluating 162 articles, reveal that most have suboptimal psychometric properties. Specifically, myriad scales possess questionable content validity as (1) items are not created in collaboration with sexual minorities; (2) measures possess a small number of items and, thus, may not sufficiently represent the domain of interest; and (3) scales are “adapted” from measures designed to examine race- and gender-based discrimination. Additional limitations include (1) summed scores are computed, often in the absence of scale score reliability metrics; (2) summed scores operate from the questionable assumption that diverse forms of discrimination are necessarily interrelated; (3) the dimensionality of instruments presumed to consist of subscales is seldom tested; (4) tests of criterion-related validity are routinely omitted; and (5) formal tests of measures’ construct validity are seldom provided, necessitating that one infer validity based on the results obtained. The absence of “gold standard” measures, the attendant difficulty in formulating a coherent picture of this body of research, and suggestions for psychometric improvements are noted. 相似文献

在美国的中小学校除英语之外讲各种语言的学生,或者说那些不会讲英语的学生,他们的教育需求长期得不到妥善的解决。1968年颁布的《双语教育法》表明,美国联邦政府承认了美国学校体制中长期存在的只能使用英语教学的单语教学问题,如何使教学语言多样性是一个亟待解决的核心问题。以霍姆斯的四模式为分析框架,把颁布《双语教育法》时纷繁复杂的社会背景置于规范模式、组织制度模式、精神状态模式和自然环境模式中进行分析,结果显示:(1)移民人口剧增并逐步扩展到新的区域,给美国公立学校造成了巨大压力;(2)司法判例对所实施的隔离但平等原则的彻底否定催生了新的希望;(3)少数族裔群体谴责主流社会的不公平,他们要求身份认同和获得更多权利的呼声愈来愈大;(4)联邦政府对保障国防安全、消除贫困现象等多重利益的考量,促成了《双语教育法》的颁布。 相似文献

从空间批评视角看,文本中的空间不再是静止的"容器",而是一种蕴含多维文化信息的指涉系统,注重文本中空间的社会、文化属性。在美国华裔作家雷祖威的短篇小说《生日》中,与华裔青年华莱士·王的爱情故事相关的几个空间场景不仅再现了华裔的现实生活世界,更充分展示了他们居于社会边缘的处境与内心疏离的痛苦。 相似文献
