On a class exhibiting trend change in average failure rate

Abstract

Weak convergence and moment convergence issues are investigated for the New Better than Average Failure Rate (NBAFR) family (introduced by Loh (1984 Loh, W. Y. 1984. A new generalization of the class of NBU distributions. IEEE Transactions on Reliability R-33 :97–113[Crossref], [Web of Science ®] , [Google Scholar])). We explore the validity of these results in the context of a more general ageing class that we introduce. We prove some new properties of this class and derive its interrelationships with other non-monotonic ageing families. Reliability and moment bounds are obtained and an interesting characterization of exponentiality is proved. Special cases of our results lead to new theorems for the NBAFR class. Finally weak convergence and related issues are established for this class.     

Stigma, HIV/AIDS and prevention of mother-to-child transmission in Zambia

This report evaluates the extent of perceived and enacted HIV/AIDS-related stigma in a rural setting in Zambia. Stigmatisation is abundant, ranging from subtle actions to the most extreme degradation, rejection and abandonment. Women with HIV and pregnant women assumed to be HIV positive are repeatedly subjected to extensive forms of stigma, particularly once they become sick or if their child dies. Despite increasing access to prevention of mother to child transmission initiatives, including anti-retroviral drugs, the perceived disincentives of HIV testing, particularly for women, largely outweigh the potential gains from available treatments. HIV/AIDS related stigma drives the epidemic underground and is one of the main reasons that people do not wish to know their HIV status. Unless efforts to reduce stigma are, as one peer educator put it, “written in large letters in any HIV/AIDS campaign rather than small”, stigma will remain a major barrier to curbing the HIV/AIDS pandemic.     

‘There Oughtta Be a Law Against Bitches’: Masculinity Lessons in Police Academy Training

This article draws on participant observation in a law enforcement academy to demonstrate how a hidden curriculum encourages aspects of hegemonic masculinity among recruits. Academy training teaches female and male recruits that masculinity is an essential requirement for the practice of policing and that women do not belong. By watching and learning from instructors and each other, male students developed a form of masculinity that (1) excluded women students and exaggerated differences between them and men; and (2) denigrated women in general. Thus, the masculinity that is characteristic of police forces and is partly responsible for women’s low representation on them is not produced exclusively on the job, but is taught in police academies as a subtext of professional socialization.

英国的刑事上诉制度研究

英国对刑事案件基本上实行两级上诉制度 :对于刑事法院的一审裁判可以依次向上诉法院和上议院上诉 ;对治安法院的裁判 ,可以分别向刑事法院或者高等法院以及上议院上诉 ,但是 ,二者的程序规则不完全相同。2 0世纪 70年代以来 ,英国上诉制度逐渐向大陆法系靠拢 ,最近英国政府再次提议进一步扩大控诉方的上诉权 ,英国上诉制度可能将发生重大变化。

孔孟治史态度之比较

孔子的治史态度是严谨的、科学的 ,孟子在治史方面却过于主观化、片面化 ,这表现在三个方面 :不同的修史原则 ,对待史料的不同态度 ,历史评价的不同标准。孔孟不同的历史观、身份和经历 ,是二人治史态度差异的重要原因。
