Improved confidence estimators for Fieller's confidence sets

Fieller's confidence set C_F for ratios of location parameters, although of great importance in practice, is often cited as an example to criticize frequentist theory. The reason is that the set can consist of the whole parameter space and yet the confidence is γ = 1 – α in any case. In this paper, we study the problem of constructing data-dependent estimators better than γ₊, A reasonable estimator appears to be γ₊, which is one if C_F is the whole parameter space and γ otherwise. By using an estimated confidence approach and a squared-error loss, it is shown that γ₊ dominates γ. The risk improvement of γ₊ over γ can be sizable. Also, by numerically comparing γ₊ with a generalized Bayes estimator γ_L, which is shown to be admissible when one or two ratios are concerned, it is shown that γ₊ is nearly admissible. We also conclude that the common practice of reporting 1 – α only when C_F is not the whole parameter space is nearly admissible.     

From Work as Sex to Sex as Work: Networks, ‘Others’ and Occupations in the Analysis of Work

While once upon a time the social science of work and organization neglected or marginalized gender and sexuality, we have now lost sight of what people actually do, that is to say the activity of work. Gender and sexuality have been identified as crucial to organizational dynamics and, notwithstanding different theoretical emphases, this paradigm has become increasingly influential. We argue (contrary to most of its protagonists) that — within this model — the significance of sex and gender for organization rests principally on their role in the production of identities rather than in what they can tell us about production or work in any wider sense. The article highlights parallels with the ways in which prostitution is now generally understood, whether the emphasis is on subordination or agency. This literature also emphasizes gender relations and identities, even where the focus is on re–writing ‘sex as work’. We argue that this focus neglects the wider networks in which all work, whether mainstream or otherwise, is embedded and that a full analysis must take due account of both these networks and the discursive production of identities. Examples — of work in the finance and sex industries — are used to substantiate this argument and a case is made for the importance of the Chicago School’s analysis of occupations.     

The Treatment of Relationship Status in Research on Dating and Mate Selection

The relationship status of study participants (e.g., daters, cohabitors, marrieds, or unmarrieds) has implications for understanding dating and mate selection. Procedures used in studies may blur or ignore status distinctions. The authors examined methods used in 791 studies published from 1991 – 2001. Most commonly, status of participants is unspecified, and different statuses are collapsed for analysis. Status of participants is associated with recruitment method, and type (e.g., romantic, friendship) and form (e.g., perceived, current) of relationship measured. Unspecified samples are associated with research on the topics of universal properties or causal conditions, and specified samples with mate selection. The connection between status and topic is becoming more blurred over time. Recommendations for studying and reporting status are provided.     

乌蒙山区农村社会转型与基督教的影响

“社会主义新农村建设”是当前构建和谐社会的现实任务的一个重要组成部分。它应该强调五个方面——“协调推进农村经济建设、政治建设、文化建设、社会建设和党的建设”。这些都密切联系到农村中新老价值观的碰撞、调适、整合,联系到社会转型。这当中,宗教作为既成的社会意识形态和社会组织系统,宗教信徒作为国家公民,都是社会运动中的参与力量与资源。宗教、社会与政府三者之间如何互动,如何实现协调合力,推动社会发展？这成为了需要认真研究的问题．本文本着“一切从实际出发,理论联系实际”的马克思主义认识论原则,重点考察苗族信教群众聚居村寨,力图把握当前西部贫困地区农村社会中,基督教对新农村社区发展的各种影响,实事求是地提出“整合社会既有资源,发展农村和谐社会”的理论思考。     

Developing Employment Opportunities for Care Leavers

This article describes an action research project carried out in North West England that aimed to assist Children’s Services Departments and Care Trusts in developing their strategies for supporting care leavers into employment and training. The study found a range of models and approaches that can be utilised to develop local and regional partnerships offering employment and training opportunities designed to meet the needs of care leavers. Relevant questions about the extent to which such opportunities should be ring‐fenced or targeted on particular fields of employment are identified. © 2010 The Author(s).

Public relations education in a divided society: PR, terrorism and critical pedagogy in post-conflict Northern Ireland

Most students entering higher education in Northern Ireland's two universities have experienced a highly segregated educational system since they were five years old. This context creates a specific set of issues and problems for the educator who wishes to engage with student groups in a critical analysis of complex and controversial topics within the curriculum. This article presents the results of a research project which was designed to assess student (and educator) experiences of studying the issue of ‘PR and terrorism’ at Northern Ireland's largest university. Data was gathered from undergraduate public relations students using survey questionnaires (administered before and after the teaching and learning experience). The educators engaged in this activity also report on their own ‘participant observation’ experiences and reflect critically upon the role academic staff might play in developing pedagogic practices which are accepting of diversity in respect to controversial and complex curriculum topics.
