Natural resource management policies like the Pacific salmon harvest policy developed by New York State often did not anticipate the extent of social, economic, and ethical concerns that would be generated, largely because the agency concentrated on biological considerations. The number of concerned stakeholders grew in proportion to both the success and failure of the initial policy. Had all participants been equally willing to recognize both the successes and the failures, development of a revised policy through group negotiations may have been possible, resulting in a cooperative mode of decision making. Instead, institutional mechanisms based on legislated process were ultimately the approach chosen for policy revision.  相似文献

The defining properties of party identification long established for the United States fail with some frequency to be replicated in electoral systems abroad. A number of plausible suggestions have been made to account for this system-level variability: Most of these have some face merit, but none taken alone is adequate to provide a full cross-system explanation. Variation in party system size or fractionalization has recently been discussed as another source of differential dynamics of party loyalties. Unfortunately, the conventional means of assessing party identification properties are subject to rather severe artifacts, typically ignored, when comparisons are made across systems of very different party size. The conceptual stakes underlying key methods options for such comparisons—most notably, between continuous and discrete statistical tools—are examined. The use of continuous statistics for systems of very multiple parties rests on an assumption that voters do in some degree regard these party systems as imbedded in a continuous space. A simple test for this assumption is mounted in four systems and unsurprisingly it shows very clear support. Analysis of residuals beyond this obvious result add several points of less obvious information about the distribution of party affect in such systems.  相似文献

Lower division and upper division college women's and men's commitment in a dating relationship was examined in connection with their (a) gender role attitudes, (b) educational aspirations, (c) certainty about their future vocation, and (d) the importance they attach to work vs. marriage as a source of life satisfaction. Dating commitment was also examined for women in relation to their dedication to work for pay after marriage, and for men in terms of their ideas about their future wife working. The more certain upper division college women's vocational identity, the more committed they were to their dating partner, but the more they planned to work after marriage the less involved they were in a relationship. Additionally, upper division women who placed more importance on a job than marriage and who had a clearer vocational identity were less involved in a relationship. The clearer upper division men's vocational identity, the more committed they were in a relationship. Lower division men who placed more importance on work compared to marriage were less involved in a dating relationship. The results are discussed in light of Erikson's stages of identity development and more recent research that suggests women's identity development follows a different course from men's.Received Ph.D. in child development and family relationships at the University of Texas at Austin.

We conducted a short-term longitudinal study examining the structure of coping behavior and the relationship between coping style and depression during adolescence. The sample consisted of 603 adolescents in Grades 6–11 who were surveyed in the fall of 1989 and again in the fall of 1990. A two-dimensional model of coping was found using confirmatory factor analysis with the factors being approach and avoidant coping. Four cross-sectional and seven longitudinal coping groups were formed to explore group differences in depression. Approach copers reported the fewest symptoms of depression, while avoidant copers reported the most. Subjects who changed over time from approach to avoidant coping evidenced a significant increase in depressive symptoms, whereas subjects who switched from avoidant to approach coping displayed a significant decrease in depression over a one-year period. These findings imply that adolescents who are able to elicit social support, engage in problem solving, and cognitively restructure events within a positive light are more likely to successfully negotiate the challenges of adolescence.This research was supported by a grant from the William T.
