We use nationally representative data to calculate correlations in achievement and delinquency between genetically differentiated siblings within a family, between peers as defined by adolescents' "best friend" nominations, between schoolmates living in the same neighborhood, and between grademates within a school. We find the largest correlations between siblings, especially identical twins. Grademate and neighbor correlations are small. Peer-based correlations are considerably larger than grademate and neighbor correlations but not larger than most sibling correlations. The data suggest that family-based factors are several times more powerful than neighborhood and school contexts in affecting adolescents' achievement and behavior. 相似文献

Marketing practices that promote calorie-dense, nutrient-poor foods directly to children and adolescents present significant public health risk. Worldwide, calls for government action and industry change to protect young people from the negative effects of food marketing have increased. Current proposals focus on restricting television advertising to children under 12 years old, but current psychological models suggest that much more is required. All forms of marketing pose considerable risk; adolescents are also highly vulnerable; and food marketing may produce far-reaching negative health outcomes. We propose a food marketing defense model that posits four necessary conditions to effectively counter harmful food marketing practices: awareness, understanding, ability, and motivation to resist. A new generation of psychological research is needed to examine each of these processes, including the psychological mechanisms through which food marketing affects young people, to identify public policy that will effectively protect them from harmful influence. 相似文献

The authors look back more than 30 years to those who introduced the use of the computer as an important new tool to assist students in the area of career development. To what extent have dreams been realized and concerns allayed? Rapid advances in technology, not included in the authors' vision, have transformed the world into a different place. How have these advances affected the use of computers in counseling? The article concludes with a list of current concerns, along with recommendations for further action and research. 相似文献

Since the first free elections were held in April 1994, South Africans are popularly known as the 'rainbow people'. The paper inquires whether South Africans who experienced pride in their nation in the first years of democracy also perceived a greater sense of subjective well-being. It is proposed that national pride in post-apartheid South Africa might be fused with or work through self-esteem to lift levels of happiness. The paper traces the history of the new integrating civil religion of the rainbow people and the acceptance of the rainbow as a political symbol of unity among the diverse people of South Africa immediately after the 1994 elections and two years later. The proposed link between national pride and happiness was explored with data from two independent national surveys, the 1995 South African World Values Survey conducted by Markinor and a June 1996 MarkData syndicated omnibus survey. The study found that the appeal of the rainbow as political symbol was inclusive of all groups in society and that feelings of national pride and support for the rainbow ideal were positively associated with subjective well-being. As indicated by intensity and frequency measures, the majority of South Africans were proud of their country and could name a national achievement that inspired pride. Better-off South Africans tended to be happier and more satisfied with life but less proud, while the poor were less happy but fiercely proud of their country. Results suggest that belief in South Africa's 'rainbow nation' ideal may have assisted in boosting happiness during the transition to a stable democracy, thereby preventing alienation among the losers under the new political dispensation. Supporters of the ideal of the rainbow nation were more optimistic than others about the future of their country. 相似文献

It has been clear since the work of Weber that the relationship between social structure and musical syntax is an important potential area of sociological investigation. Little work has been done in this area, however, probably because of methodological problems. Discussions of methodological problems in analyzing meanings in music converge in music theory and sociology on the issue of objectivity. Recent comparisons of musical syntax with language and the work of Heinrich Schenker in music theory provide the basis for an interdisciplinary methodology for analyzing typified collective meanings communicated through musical syntax. It is suggested that, on the basis of this methodology, these collective meanings could be analyzed “objectively.” Two examples of this approach are provided through typified collective musical expressions of love and death. 相似文献
