Romantic activity is a social psychological phenomenon. Gender, race, and peer networks are key contexts for understanding the social construction of this behavior as gender‐ and race‐based norms structure feelings and behaviors that define “appropriate” romantic activity and peer networks serve as incubators of this activity. With a nationally representative sample of adolescents (N= 8510) drawn from the National Longitudinal Study of Adolescent Health, this study explored the linkages among peer networks, conceptions of idealized romantic relationships and actual romantic relationships, and the ways in which gender and race moderate these associations. Several characteristics of peer networks predicted adolescent attitudes about romantic behaviors as well as actual romantic behavior. Moreover, the linkages among peer networks, romantic attitudes, and romantic behaviors varied by race.  相似文献

Our study focuses on maritime pilotage in seven European countries and analyzes the level of job satisfaction and its predictors. Like most existing studies in the field of job satisfaction, we show that job satisfaction is an outcome of the work of maritime pilots. Stressful working conditions, such as working unsocial hours and irregular working patterns, create strains that together with intervening factors related to work, family, or the work environment ultimately reduce job satisfaction. However, our results indicate that although negative physical and social consequences are important, they are neither the strongest nor the only variables determining job satisfaction. Another effect seems more important in European maritime pilotage: Job satisfaction is instead a predictor of how much pressure and stress pilots can handle. Despite health problems and a reduction in their quality of life due to working unusual hours, most maritime pilots do not regret their choice of profession. Factors to ameliorate the working conditions are also identified. The most important parameters include alterations in working time systems, working conditions which minimize physical strain, fairness regarding payment, flexibility within the compensation system, an intensification of the possibilities for involvement and participation, an extended degree of co-determination, and the distribution of the ownership of the pilot stations.  相似文献

Conclusion I have attempted to distill a quite sizable body of literature written by modern economists on the theory of labor unions, with particular emphasis given to the “two faces” view of unions developed by Freeman and Medolf in What Do Unions Do? Many important ideas and contributions have necessarily been omitted, but hopefully the main contours and implications are captured.  相似文献

Younger and older adolescents were interviewed about their goals in recent disagreements with their mothers. Six goals were identified: instrumental (simply gaining their immediate desire); dyadic concern; achieving emotional support; autonomy; dominance; and nonengagement (avoidance of conflict). Younger adolescents reported significantly more instrumental and significantly fewer emotional support and dominance goals than did older adolescents. Maternal perspective‐taking predicted more dyadic concern and fewer dominance goals, as well as more nonengagement goals for younger adolescents. Dominance goals mediated the effect of maternal dyadic perspective‐taking on conflict intensity for older adolescents.  相似文献

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。  相似文献

The study found an increasing number of ventilator dependent children and young people living at home. Almost three quarters of the sample had a physical disability as a result of or in addition to their primary diagnosis. There was wide variation in the amount of paid care supporting these families which appeared unrelated to the level of ventilatory dependence. Nurses working in community children's teams or hospital outreach teams were the most frequent care organisers and care managers. The majority of the care packages were funded by Health Authorities.  相似文献
