Differences in statutory mandates, traditions, and attitudes toward risk cause agencies to develop different standards for the same substances. As a response to this fragmentation and uncertainty, common to environment decisions, new organizations emerge to try to coordinate the agencies but usually are created to perform a specific task rather than to coordinate agencies. For these new organizational forms to succeed, they must be in place before the crisis occurs and they must be able to facilitate, not impede, normal adaptive mechanisms of organizations.  相似文献

A sample of 689 adolescents (grades 7–12) from two Midwestern communities who had been identified by peers as members of one of three major peer groups responded to a self-report survey measuring perceptions of peer pressure in five areas of behavior: involvement with peers, school involvement, family involvement, conformity to peer norms, and misconduct. Perceived pressures toward peer involvement were particularly strong, whereas peer pressures concerning misconduct were relatively ambivalent. Perceived pressures toward misconduct increased across grade levels and pressures to conform to peer norms diminished; grade differences in perceived peer pressures concerning family involvement were community specific. Compared to druggie-toughs, jock-populars perceived stronger peer pressures toward school and family involvement, and less pressure toward (stronger pressure against) misconduct; patterns of perceived pressure among loners were more variable across communities. Results elaborated the process of peer influence in adolescent socialization and identity development.A version of this paper was presented at the biennial meetings of the Society for Research in Child Development, Toronto, April 1985.

In presidential nomination campaigns, individual state primaries and a national competition take place simultaneously. The relationship between divisive state primaries and general election outcomes is substantially different in presidential campaigns than in single-state campaigns. To capture the full impact of divisiveness in presidential campaigns, one must estimate both the impact of national party division (NPD) and the impact of divisive primaries in individual states. To do so, we develop a comprehensive model of state outcomes in presidential campaigns that incorporates both state-level and national-level controls. We also examine and compare several measures of NPD and several measures of divisive state primaries found in previous research. We find that both NPD and divisive state primaries have independent and significant influence on state-level general election outcomes, with the former having a greater and more widespread impact on the national results. The findings are not artifacts of statistical techniques, timeframes or operational definitions. The results are consistent—varying very little across a wide range of methods and specifications.  相似文献
