This article presents a conceptual framework for analysing the governance of natural resource use, as governance is often the primary issue when natural resources are overexploited and degraded. It addresses both spontaneous and active governance, including institutional change induced by development co‐operation. Drawing on existing frameworks of institutional analysis, fundamental modifications are presented to adapt the concept to the context of international co‐operation, and to include dynamic aspects of institutional change as well as multiple actor interactions. Tested in several case studies, the framework was found suitable and relevant for use in project planning and evaluation, as well as for comparing governance issues across cases in a conceptually rigorous way.

Although there has been evidence for some time of a sex difference in depression, relatively little research has examined the developmental process by which women come to be at greater risk than men for depression. In this paper, the developmental pattern of depressed affect is examined over early and middle adolescence, with a special focus on the patterns of boys as compared to girls. In addition, a developmental model for mental health in adolescence is tested for its power in explaining the emergence of gender differences in depression. Longitudinal data on 335 adolescents randomly selected from two school districts were used to test the hypotheses. Results revealed that girls are at risk for developing depressed affect by 12th grade because they experienced more challenges in early adolescence than did boys. The sex difference in depressed affect at 12th grade disappears once early adolescent challenges are considered.This research was supported in part by grants MH30252/38142 to A. Petersen.

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.

In response to the perceived failure of both the state and market models of service delivery, governments have embarked on a reform program that draws on the community sector to expand the suite of available policy and service delivery arrangements. This paper explores and identifies the nature of changed relationships between government and the community sector. It uses a case study that examines the operation of a new type of community organisation, and analyses the affectivity and outcomes from the experience of a community based networked arrangement. Although there is evidence of a shift to more relationship‐ oriented models of operation because of either mandate or preference both community and government sectors have found it difficult to make the necessary adjustments to these new ways of working. Community has begun the shift to this new relational approach but finds it difficult to sustain the momentum and tends to revert to more independent and competitive modes. Governments find it difficult to make the necessary adjustments to power‐sharing and resource allocation and continue to operate as ‘business as usual’ through the traditional bureaucratic authority of command and control. In this way, the rhetoric of collaboration and partnership between government and the community sector is not necessarily matched by policy and action supporting the practice of ‘new ways of working’ although these ‘experiments in service delivery’ have opened the way for adopting more innovative and effective approaches to service delivery.  相似文献

Despite widespread institutional and professional support, the recommendations of the Bristol Royal Infirmary Inquiry may be insufficient to reduce patient risk from impaired senior medical practitioners. Using the First Inquiry into Neurosurgical Services at the Canberra Hospital as a case study, this article argues that the Bristol-type recommendations--which emphasise reformulation of clinical governance structures, including early reporting of "sentinel events" and compulsory clinical audits--will be ineffective without a reformed institutional ethos that encourages open transparency and respect for those committed to such processes. Such reformulation may need to commence in medical education and involve new strategies including the use of portable digital technology to facilitate self-assessment of performance and immediate reporting of adverse incidents.  相似文献
