Goodness‐of‐fit methods for matched case‐control studies

The authors propose graphical and numerical methods for checking the adequacy of the logistic regression model for matched case‐control data. Their approach is based on the cumulative sum of residuals over the covariate or linear predictor. Under the assumed model, the cumulative residual process converges weakly to a centered Gaussian limit whose distribution can be approximated via computer simulation. The observed cumulative residual pattern can then be compared both visually and analytically to a certain number of simulated realizations of the approximate limiting process under the null hypothesis. The proposed techniques allow one to check the functional form of each covariate, the logistic link function as well as the overall model adequacy. The authors assess the performance of the proposed methods through simulation studies and illustrate them using data from a cardiovascular study.     

Domains of convergence for the EM algorithm: a cautionary tale in a location estimation problem

The EM algorithm is a popular method for maximizing a likelihood in the presence of incomplete data. When the likelihood has multiple local maxima, the parameter space can be partitioned into domains of convergence, one for each local maximum. In this paper we investigate these domains for the location family generated by the t-distribution. We show that, perhaps somewhat surprisingly, these domains need not be connected sets. As an extreme case we give an example of a domain which consists of an infinite union of disjoint open intervals. Thus the convergence behaviour of the EM algorithm can be quite sensitive to the starting point.     

TOWARD A SOCIOLOGY OF CULT FILMS: Reading Rocky Horror

This article provides a sociological reading of cult films, in particular, The Rocky Horror Picture Show. Cult films are secular documents, celebrated as sacred texts by audiences and used as shared foci to collectively create rituals and belief systems. They differ from popular re-releases, fad films, films with cult qualities, and critical cult films in that they involve typical people in atypical situations, sympathetic deviance, challenges to traditional authority, reflections of societal strains, and paradoxical and interpretable resolutions. Examination of the Rocky Horror text and the cult activities that occur during its viewing, reveal it as a paradoxical indictment and validation of traditional societal arrangements.

私募股权投资参与、企业社会责任与盈利能力研究——基于新三板的数据

本文以251家新三板私募股权投资基金支持企业为样本,研究了企业社会责任履行与盈利能力之间的关系.研究发现:企业对政府、股东、债权人、管理层、员工、客户、社会大众负责与企业盈利能力存在显著的正相关关系.投资企业的PE个数与企业盈利能力显著负相关.企业对供应商负责、PE总投资额与盈利能力没有显著相关性.     

在粤印度人状况初探

在粤印度人( 主要是生活在珠三角的印度人) 和整个在华的印度人一样,是一个非常独特的群体。他们以自己特有的方式生活、工作、学习或拓展自己的生意,一直保持着自己独特的生活方式和行为方式,坚持自己的文化特点,在各方面都显示出自己鲜明的特征。印度人在华的商业成功或在中国获得的机会吸引了更多的印度人来到中国。在华印度人,尤其是在粤印度人的人数将会不断增长,中、印通婚的人数也会不断地增加。这对中、印两国关系的方方面面均会产生重大的影响。     

河北省高校周边文化圈建设研究

建设河北特色文化大省，实现文化大发展、大繁荣，是时代的课题。高校和地方文化各自独立发展，缺乏竞合的现状是制约河北文化发展的一个难题。高校周边文化圈建设是解决这一难题、建设文化特色大省的有效途径，河北省政府牵头，协调高校，以地方文化为主体，采取以点带面的形式，逐步实现文化圈的建设。     

HPV vaccine acceptance among a sample of Southern men who have sex with men: A comparison of younger and older men

Objectives: Do short, online educational messages about the human papillomavirus (HPV) influence younger and older men who have sex with men (MSM) differently? Second, what are the HPV knowledge levels and risk perceptions of Southern MSM living outside of major metropolitan areas? Methods: This study draws on participants who completed an anonymous online survey asking about their knowledge, risk assessment, and vaccine acceptance regarding HPV. Results: Knowledge about HPV was low among the MSM in this study. After reading a one-page information intervention, vaccine acceptability increased by a statistically significant amount among both a Younger and Older cohort but risk perception only increased among the younger respondents. Single men regardless of age cohort reported sharper increases in perceived risk after the intervention, but relationship status did not produce significant differences in vaccine acceptability. Conclusion: Online, brief interventions may be effective means of increasing motivation to vaccinate among Southern MSM.
