The paper describes the historical development of metropolitan planning and administration in Metro Manila, and identifies five major problems: the sectoral isolation of planning; the inadequate involvement of local government; inadequacies in planning methods; weaknesses in the system of resource management; and institutional fragmentation. The development of the Capital Investment Folio process, its institutional framework and the main characteristics and results of applying the approach are described. The benefits and lessons which have emerged are then set out and their possible application elsewhere discussed. The main achievements of CIF are progress towards a rational system of urban planning; the generation of consensus within government about Manila's investment strategy; a more widespread appreciation of opportunity costs; and a new understanding of how to plan under conditions of uncertainty. It remains for CIF to be integrated into the national resource allocation process, and to be fully accepted by national government agencies. Local government still needs to be positively involved in the planning process.  相似文献

Sexual decision making, perceptions of responsibility for birth control and pregnancy, and knowledge of contraception and the consequences of teenage pregnancy were assessed among 251 high-risk seventh- and eighth-grade black, inner-city adolescents to determine these young peoples' need for information. Survey results indicated that these adolescents were aware of contraceptive methods, but lacked practical information about requirements for obtaining them or method effectiveness. Many students were uninformed about the circumstances under which pregnancy can occur. Males indicated a willingness to have intercourse, regardless of the contraceptives used, if any, and believed responsibility for use of a birth control method belonged to females. Females believed themselves to be responsible for contraceptive utilization and preferred intercourse with adequate protection. Both genders endorsed the notion of mutual responsibility for an unplanned pregnancy and related decisions. Implications for school-based family life education programs for young adolescents are discussed.This research was supported by grants from the Illinois Department of Children and Family Services and the Pittway Charitable Trust, to the Center for Health Services and Policy Research of Northwestern University; the project was administered by the Ounce of Prevention Fund. Portions of this paper were presented at the 112th annual meeting of the American Public Health Association at Anaheim, California, November 1984. Conclusions or opinions expressed in this article are those of the authors and do not necessarily reflect the views of the Center for Population Options, Northwestern University, or the State University of New York at Buffalo.Received Ph.D. from Loyola University of Chicago.

Abstract: There is an ambivalence in attitudes to public administration as a field of study among both academics and practitioners in Australia. Teachers, researchers, students, public servants seeking training and managers have differing interests and expectations. Disagreements about the field have contributed to the lack of a unified framework of concepts, while the field has fragmented into public administration, public policy and public management, aside from other divisions such as "old" versus "new" public administration. "Education" and "training" have taken diverging paths and academics and practitioners have drifted apart. There needs to be a closer dialogue that can only be based on a generally agreed paradigm for Australian Public Administration as a field of study.  相似文献
