Further applications of bias to discriminant analysis

This article extends the biased minimum x² rule to the unequal covariance matrix case and to the case of several populations, The biased procedure is shown to improve the performance of the commonly used classification procedures. Results of sampling experiments over a broad range of conditions are provided to demonstrate this improvement.     

Childhood sexual experiences and the perception of abuse among latino men who have sex with men

There is a lack of consensus on how to define childhood sexual abuse (CSA). In this study we explore the perceptions of CSA among men who had such experiences. One hundred Latino men (predominately gay) who had childhood sexual experiences with an older partner (CSEOP) were asked whether they considered their experiences sexual abuse (41 said no; 59 said yes). Those who felt abused were younger when the events happened and were more likely to have been physically forced, physically hurt, threatened, and emotionally hurt. Negative correlates of CSEOP in adulthood were also explored. Men who considered themselves the victims of CSA differed from those without CSEOP in having more alcohol use, unprotected anal sex, and male sex partners.

现代传媒文化的病灶根源

20世纪大众传媒文化的兴起改变了过去几千年来形成的传统文化景观.现代传媒文化在市场利润的诱惑下沦为商业文化,这种文化因为过度迎合一般大众趣味,从而伤害到传媒文化理性本身;战争期间传媒被各国政府严加控制,传媒多数沦为战争宣传机器,这在历史上同样引发了人们对传媒文化的恐惧;20世纪也是一个民主观念盛行的世纪,民主以及传媒被不同集团或者政党所利用,从而对传媒文化理性造成另外一种伤害.     

汉语中的日源外来词

Public Relations and Chinese Modernity: A 21st-Century Perspective

ABSTRACT

This study approaches the history of China's public relations (PR) industry from the perspective of modernity. Coupled with China's modern transformation and modernization since the late 1970s, Chinese PR industry and practitioners sought to establish legitimacy in the following 30 years. Three developmental stages are identified: Introduction and Enlightenment (1978–1992), Marketization and Professionalization (1992–2003), and Diversification (2003–present). In each stage, the theme and practice of PR interplayed with China's modernization and modern transformation. Situated under unique political, economic, and social contexts, China's PR faced, and is still facing, crises in reputation, utility, social values, identity, legitimacy, and professional ethics.     

Cultural tourism and temporary art exhibitions in Italy: a panel data analysis

The main aim of this work is to study the relationship between cultural tourism and temporary art exhibitions by means of a panel data analysis. In literature, the capability of cultural attractions, e.g. art exhibitions, of increasing the tourist flow has not been investigated yet and we start to fill this gap. Our data set consists of monthly observed variables on 52 Italian provinces over the period 2003–2007. Our response variable is the amount of hotel arrivals and the set of covariates includes the amount of visitors of temporary exhibitions of ancient, modern and contemporary art plus a set of variables that contribute to tourist arrivals, like the kind of destination, the attraction capability of each province and so on. Of particular interest is to discover the art sector that has the strongest influence on the tourist flow towards Italy by keeping into account both the temporal dynamic and the heterogeneity of the Italian provinces. To this aim, we discuss the static and dynamic error component regression models from both the theoretical and practical point of view. The estimated two-way fixed effects regression models suggest that all the three sectors contribute to the tourist flow but in a quite different fashion. On the basis of our analysis we derive some indications for the policy maker in the field of cultural tourism.

Trends in the participatory process of changing shiftwork arrangements

Abstract

A recent survey by the International Labour Office on changing shiftwork arrangements showed that there were three essential steps commonly taken in the change process in different countries. They could be identified as: (1) group study of operational requirements and workers' needs; (2) establishing feasible options; and (3) consensus building while acting on conflicting interests. The change process was more successful when it was provided with concrete support. Attention is drawn to three major aspects of such support: (a) gathering data about operational requirements of the enterprise and workers' needs and preferences (by applying practical methods such as questionnaire surveys, interviews, group discussion and workshops); (b) support for the participatory development of plans for new arrangements (by organizing a group involving workers' representatives); and (c) training support for facilitating the group work and bargaining required for consensus building. Locally adapted training support is necessary particularly about: (1) understanding shiftwork effects and generally accepted guidelines; (2) how to find feasible options based on gathered data and these guidelines; and (3) how to cope with shiftwork. Thus support from people experienced in facilitating the well-informed, participatory process of change will need to be developed for promoting the improvement of shiftworking conditions.
