Binary designs are not always the best

We give an example of a nonbinary block design which is better than any binary design with respect to the E-optimality criterion. This shows that the class of binary designs is not essentially complete, at least with respect to E-optimality.     

An overview of present and future emigration dynamics in South Asia

The author presents preliminary findings on selected aspects of the dynamics which govern emigration from and within the South Asian region comprised of Bangladesh, India, Pakistan, and Sri Lanka. The paper attempts to identify some of the major reasons for observed migration flows and how the future may be envisaged especially in view of government programs, policies, and priorities. Contract labor migration is given special attention since it has become the predominant type of migration in the region. Sections consider a possible conceptual framework; measuring emigration pressure or potential; data and data problems; the volume of emigration since 1970; South Asian migrant workers; macro-level determinants of emigration; community, family, and individual factors; and sending country policies. The consequences of emigration are discussed in terms of the impacts upon the labor force and non-economic consequences. Observations for the future conclude the paper. Analysis of the dynamics of emigration from South Asia indicate an urgent need to improve data on various forms of emigration, that relevant officials in countries of origin have a longstanding concern about the exploitation of workers in sending as well as receiving countries, and the need to better understand the linkages between various factors relevant to the emigration process. An understanding of such linkages would allow for more realistic policies and planning for future emigration.     

Arab labour migration: a review of trends and issues

"The objectives set for this paper are to: provide an analysis of volume and trends in labour migration within the Arab region; discuss the major characteristics of the migrants, including demographic features, types of economic activity, wage levels and duration of stay in host countries; [and] outline and discuss the major issues in labour migration both from the sending and receiving countries. The time period covered by the study is from the mid 1970s to the present." (SUMMARY IN FRE AND SPA)     

Are peer educators really peers?

OBJECTIVE, PARTICIPANTS, AND METHODS: To determine whether peer educators are considered peers by their audiences, the authors compared 28 peer educators and 28 college students on their personal qualities using self-report surveys. RESULTS: Students who wanted to become peer educators reported higher self-esteem, greater leadership skills, and fewer risky health behaviors than did demographically similar college students. However, peer educators appeared similar to their colleagues in terms of personal values and personality temperament. CONCLUSIONS: Although peer educators are natural leaders with strong self-esteem and more healthy behaviors, they appear to be quite similar to their audiences in regard to values and temperaments, making them successful role models and arguably true peers.     

当代大众文化对青年价值取向的影响

文化建构人的价值意识。改革开放以来,大众文化日益成为青年成长的主要文化情境。青年价值取向,是青年心理与周围文化世界的有机契合,在青年对大众文化的热情追随和狂热消费中,世俗与低俗共生、回归与沉沦同奏、感性与泛感性交织,呈现出前所未有的新格局。加强大众文化建设和创新青年价值观教育是提升当代青年价值取向的现实选择。     

Toward a generation free of tuberculosis: TB disease and infection in individuals of college age in the United States

Objectives: To assess the magnitude of active TB disease and latent TB infection (LTBI) in young adults of college age. Participants: Individuals who were aged 18–24 years in 2011 were used as a proxy for college students. Methods: Active TB cases reported to the 2011 US National TB Surveillance System (NTSS) were included. LTBI prevalence was calculated from the 2011–2012 National Health and Nutrition Examination Survey. The 2011 American Community Survey was used to calculate population denominators. Analyses were stratified by nativity. Results: Active TB disease incidence among persons aged 18–24 years was 2.82/100,000, 18.8/100,000 among foreign-born individuals and 0.9/100,000 among US-born individuals. In 2011, 878 TB cases were reported; 629 (71.6%) were foreign-born. LTBI prevalence among persons of 18–24 years was 2.5%: 8.7% and 1.3% among foreign-born and US-born, respectively. Conclusion: Active screening and treatment programs for foreign-born young adults could identify TB cases earlier and provide an opportunity for prevention efforts.     

董事激励与公司业绩--实验的证据

我们在实验框架下检验了董事会成员的激励对股东财富和CEO报酬的影响,以及该报酬与公司业绩之间的敏感度.文中提出了两种任命董事的方法,一种由CEO任命,另一种由最大的股东自动担任董事.由董事会决定CEO的报酬,而CEO负责企业的生产、投资和分红决策.投资者根据接收到的每个公司的分红、资本收益这些信息,通过买卖这些企业的股票来调整他们的资产组合. 我们发现,薪酬与业绩之间的敏感度随董事持股比例的增加而上升.此外,当大股东作为董事会成员时,经济体所产生的财富(股东财富是其中的一部分)更大;而当CEO选择董事时,结果是缺乏效率的.本文讨论了关于董事职能和相关代理成本这一研究结果,以及标准会计框架下,限制执行人员报酬和报表标准化要求.     

Iconizing “Muslim Terrorism” in a British Newspaper and Public Perception

By examining a news story and reader responses published in the Daily Mail Online (DMO), our study discursively argues that this daily newspaper promotes an Orientalist perception of Islam and Muslims. The religion and its adherents are both framed and perceived as a threat to British society and its “Western values”, thus reinforcing Islamophobia within society. This study also argues that the DMO espouses the perceived Orientalist threat posed by Islam through juxtaposition, exaggeration and manipulation of facts, through lexical choices and visual images that eventually establishes the perception of a cultural clash. In addition, by examining the readers’ responses toward the news story, this study demonstrates that the vast majority of respondents perceive Islam and Muslims as a threat to “the West”. Their comments, as triggered by the text, also contribute to the discourse of Islamophobia and the perceived Orientalist view of an Islamic threat.     

Be Careful Where You Smile: Culture Shapes Judgments of Intelligence and Honesty of Smiling Individuals

Smiling individuals are usually perceived more favorably than non-smiling ones—they are judged as happier, more attractive, competent, and friendly. These seemingly clear and obvious consequences of smiling are assumed to be culturally universal, however most of the psychological research is carried out in WEIRD societies (Western, Educated, Industrialized, Rich, and Democratic) and the influence of culture on social perception of nonverbal behavior is still understudied. Here we show that a smiling individual may be judged as less intelligent than the same non-smiling individual in cultures low on the GLOBE’s uncertainty avoidance dimension. Furthermore, we show that corruption at the societal level may undermine the prosocial perception of smiling—in societies with high corruption indicators, trust toward smiling individuals is reduced. This research fosters understanding of the cultural framework surrounding nonverbal communication processes and reveals that in some cultures smiling may lead to negative attributions.
