Long-term dynamics of household size and their environmental implications

Little is known about the environmental implications of long-term historical trends in household size. This paper presents the first historical assessment of global shifts in average household size based on a variety of datasets covering the period 1600–2000. Findings reveal that developed nations reached a threshold in 1893 when average household size began to drop rapidly from approximately 5.0 to 2.5. A similar threshold was reached in developing nations in 1987. With the notable exceptions of Ireland, and England and Wales in the early 1800s, and India and the Seychelles in the late 1900s, the number of households grew faster than population size in every country and every time period. These findings suggest accommodating housing may continue to pose one of the greatest environmental challenges of the twenty-first century because the impacts of increased housing present a threat to sustainability even when population growth slows. Future research addressing environmental impacts of declining household size could use an adapted IPAT model, I = PHoG: where environmental impact (I) = population × personal goods (P) + households × household goods (HoG).     

Everyday Sexism: Evidence for Its Incidence, Nature, and Psychological Impact From Three Daily Diary Studies

Three daily diary studies were conducted to examine the incidence, nature, and impact of everyday sexism as reported by college women and men. Women experienced about one to two impactful sexist incidents per week, consisting of traditional gender role stereotypes and prejudice, demeaning and degrading comments and behaviors, and sexual objectification. These incidents affected women's psychological well-being by decreasing their comfort, increasing their feelings of anger and depression, and decreasing their state self-esteem. Although the experiences had similar effects on men's anger, depression, and state self-esteem, men reported relatively fewer sexist incidents, suggesting less overall impact on men. The results provide evidence for the phenomena of everyday prejudice and enlighten our understanding of the experience of prejudice in interpersonal encounters from the perspective of the target.     

Role of social welfare in European suicide prevention

Yur'yev A, Värnik A, Värnik P, Sisask M, Leppik L. Role of social welfare in European suicide prevention The aims of this study were to assess the relationship between suicide mortality and social expenditure in 26 European countries, explore attitudes towards welfare systems and their relationship with suicide mortality, and compare attitudes towards welfare provision in Eastern and Western Europe. The World Health Organization suicide data and Organisation for Economic Co‐operation and Development social expenditure data for 1980–2005 were used. Data on attitudes towards welfare systems were taken from the European Social Survey. Differences between mean scores for attitudes in Western and Eastern European countries were calculated. Correlations between social expenditure and suicide trends were negative in most countries for both genders. Inverse correlations between attitudes towards welfare provision and suicide mortality rates were demonstrated for males only. Differences in attitudes were found between Eastern and Western European countries; for example, confidence in the welfare system was found to be stronger in Western Europe. Higher social expenditure and greater confidence in welfare provision appear to have suicide‐preventive effects.     

Commercial sex between men: A prospective diary‐based study

This paper describes the results of a self‐reporting dairy completed by 186 male sex workers (MSWs) over a 2‐week period in Brisbane, Sydney, and Melbourne, Australia. The diary was completed following each commercial sex encounter by the MSW. The results reveal that MSWs reported 2088 commercial sex encounters during the study period, with an average of 11.2 encounters per MSW. The majority of sex encounters took place in either the client's or the MSW's residence, with significant variations by city. The average sexual encounter lasted 70 minutes, and comprised two sexual acts, masturbation and oral sex. Condom use was reported in 67.4% of all the encounters. Using the AIDS Council safe‐sex classification system, the majority of the commercial sex encounters fell in the “safer sex” category; however, there were significant differences by source of clients and place of the encounter. Use of drugs and alcohol reveal interesting patterns: Clients were more likely to use alcohol, while MSWs had significant differences of usage of the different drugs. This study demonstrates that the majority of MSWs are offering and practicing safe sex behaviours, however, MSWs working in the street setting are still likely to be practising unsafe sex. Male sex work is becoming an organised business and this provides opportunities to implement further public health interventions.     

Returns vs. Endowments in the Earnings Attainment Process for Metropolitan and Nonmetropolitan Men and Women1

Abstract Three explanations typically are offered for differences in earnings: (1) individuals have different levels of human capital and hold different jobs (endowments differ), (2) rewards to human capital and job characteristics differ (returns differ), and (3) some combination of differences in endowments and returns explain variations in earnings. We argue that the structure of labor markets in nonmetropolitan (nonmetro) areas differs from that in metropolitan (metro) areas such that returns, as well as endowments, vary. These variations in returns favor metropolitan workers, explaining the predominant portion of the metro/nonmetro earnings gap. We examine the earnings differences for metro and nonmetro men and women in both 1977 and 1987, showing that returns outweigh endowments in explaining that gap for both men and women, although their importance decreases over the ten-year period. Research to improve our understanding of how differences in labor market structure produce differential returns has begun and may yield yet another avenue for action for policymakers interested in reducing metro/nonmetro inequalities.     

早期酋长制群体的聚落形态比较研究——以内蒙古东部、安第斯山北部和美洲中部三个地区为例

对内蒙古东部、安第斯山北部和美洲中部三个地区的早期酋长制群体的聚落形态进 行的比较研究表明,尽管这三个地区的发展过程大致相当,但在这三个地区中,大体类似的转变 却以不同的方式发生,从而导致了三个各具特色的等级社会的出现。最初的、大规模的、以等级 制度原则组织起来的酋长制群体出现后,其发展轨道的早期阶段明显地为后来的、较大的、更复 杂的政治实体即国家的出现创造了条件。通过地域性聚落分析,可以发现这三个地区在不同规模 层次上的人口和社会组织的异同,其中在赤峰和奥哈卡(Oaxaca)地区都存在的小型群体却不见 于马格达雷那高地(AltoMagdalena)的现象,需要进行更深入的研究,才能进一步揭示出在马 格达雷那高地是什么样的社会交流把这些家庭联合成更大的社会团体。     

Environmental policy in the context of swedish political culture

The article describes the development of Swedish environmental policy by paying attention to the context of Swedish political culture. It describes the successes and, mainly, the failures of Sweden's environmental policy since the late sixties and traces its less‐than‐satisfactory state to the political culture of a welfare state which for a long time tended to view environmental concerns as likely to upset the socio‐economic welfare policies based on cost‐effectiveness and anti‐inflationary policies.     

Personal, health, academic, and environmental predictors of stress for residence hall students

The authors studied contributors to stress among undergraduate residence hall students at a midwestern, land grant university using a 76-item survey consisting of personal, health, academic, and environmental questions and 1 qualitative question asking what thing stressed them the most. Of 964 students selected at random, 462 (48%) responded to the survey. The authors weighted data to reflect the overall university-wide undergraduate population (55% men, 12% minority or international, and 25% freshmen). Women and US citizens experienced greater stress than did men and non-US citizens, respectively. Frequency of experiencing chronic illness, depression, anxiety disorder, seasonal affective disorder, mononucleosis, and sleep difficulties were significant stress predictors. Although alcohol use was a positive predictor, drug use was a negative predictor of stress. Both a conflict and a satisfactory relationship with a roommate, as well as a conflict with a faculty or staff member, were also significant predictors of stress.
