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

Abstract: This study compares and contrasts approaches to the management of financial stress and restraint in four Canadian provincial governments in the period from 1983 to 1985. It indicates that a number of different approaches to restraint management are utilized by Canadian provinces to cope with shortfalls in revenue and policy changes that influence resource allocation decision-making. The four provinces reviewed - British Columbia, Saskatchewan, Manitoba and Nova Scotia - have managed restraint in different ways, each reflecting the politics and the socio-economic and cultural context within which government resource allocation decisions are made. Profiles of these provinces indicate how these factors have influenced financial stress management and budget control strategy. Provincial experience is compared on the following dimensions: overall restraint management strategy; employment policy; marketing the need for restraint; centralized versus participatory government decision authority and control; the use of evaluation in restraint decision-making; and the influence of ideology in restraint management strategy-setting. Sommaire: Cette étude compare et oppose les méthodes de gestion financière adoptées en période d'austérité budgétaire par quatre gouvernements provinciaux au Canada, de 1983 à 1985. Elle indique que les provinces du Canada suivent diverses orientations en matière de gestion durant une période d'austérité budgétaire pour faire face aux manques de revenus et aux changements de politiques qui influencent les décisions d'allocation des ressources. Les quatre provinces étudiées, c'est-à-dire la Colombie-Britannique, la Saskatchewan, le Manitoba et la Nouvelle-Écosse, ont chacune adopté une orientation différence, reflétant le contexte politique, soeio-économique et culturel particulier dans lequel sont prises les décisions gouvernementales d'allocation des ressources. Les profils de la Colombie-Britannique, du Manitoba, de la Nouvelle-Éeosse et de la Saskatchewan précisent la manière dont ces facteurs ont influé sur la gestion de I'austérité financière et la stratégie de contrôle budgétaire. La comparaison entre les provinces porte sur les aspects suivants: 1) stratégie globale de gestion en période d'austérité, 2) politique d'emploi, 3) sensibilisation du public au besoin d'austérité, 4) autorité et contrôle décisionnels concentrés ou participatoires de la part du gouvernement, 5) rôle de 1'évaluation dans la prise des décisions en période d'austérité, et 6) influence de l'idéologie sur la définition des stratégies de gestion de l'austérite.  相似文献

This research attempted to more adequately dimensionalize the study of affective family relations during adolescent pubertal maturation by employing a multivariate approach. Fifty-one families responded to an assessment battery consisting of a series of questionnaires designed to measure affective relations between parents and their adolescent children. Families were classified into prepubertal, transpubertal, or postpubertal groups according to their modal response on pubertal status criteria. A stepwise discriminant analysis was performed to identify measures that maximize between groups differences. Based on this analysis, a correct classification rate of 70% was achieved for all families. The two significant discriminant functions that emerged indicate that differences in family relationships are due to the transformation of mother-adolescent and father-adolescent relations. The pattern of results replicate those of other researchers and provide elaborations concerning the affective nature of family relations during adolescence.Received his Ph.D. in Life-span Developmental Psychology from West Virginia University in 1984.

This study examines the correlation between family variables and delinquency (both self-reported and official) in a small sample of British teenage girls. Factor analysis of the 72-item Home Life Questionnaire (from T. H. Hirschi [1969] Causes of Delinquency, University of California Press, Berkeley) revealed a clear four-factor structure of caring and communication, discipline, pressure and mother-daughter closeness, which cumulatively accounted for 31% of the variance. Multiple regression of these factors onto self-reported delinquency indicated the maternal factor to be most powerful, explaining 25% of the variance in self-reported delinquency. Institutionalized and noninstitutionalized girls showed only chance differences in terms of the quality of their home life.Anne Campbell's research interests are in sex differences in antisocial behavior, especially aggression.  相似文献

In Study 1, 605 adolescents estimated how well their parents knew them and said how much they cared what their parents thought about them. Sons and daughters judged that mothers knew them fairly well, but daughters judged that fathers did not know them so well. At the same time, statements of caring indicated high concern by sons and daughters for both parents. A supplemental result was that sons from white-collar families gave relatively low estimates of how much their mothers knew them and daughters from blue-collar families gave very low estimates of how much their fathers knew them. In Study 2, 52 adolescents from single-parent families and living with their mothers but not with their fathers also gave estimates for knowing and caring. Knowing followed the above pattern, with an expected lowering of estimates for fathers by sons and daughters. Further, estimates of caring declined especially for fathers by daughters. These results add to the growing literature that shows mother-adolescent and father-adolescent relationships contribute differentially to psychological development. The results seem especially relevant for adolescents' sex role development and constructed individuality as mediated through relationships with both parents.Received Ph.D. in experimental psychology from The Catholic University of America.

This study examined the involvement and satisfaction of adolescents with their fathers and mothers. Possible age and sex differences were investigated for three components of involvement: proportion of time spent with fathers and mothers, type of activities engaged in, and degree of satisfaction with those activities. Telephone interviews were used to obtain information about previous day's activities from 61 adolescents in grades 6–12. For each activity, data were obtained on duration, who else was present, and satisfaction. Results indicated that adolescents spent a greater proportion of time in leisure than in work with fathers, and equal time in work and in leisure with mothers. In general, adolescents were as satisfied with activities with their fathers as with their mothers. Adolescents enjoyed working with fathers more than mothers, however. The results demonstrate that activity satisfaction varies as a function of what activities adolescents engage in and who is present.Received his Ph.D. from Michigan State University.

In 1982, disabled workers who came on the social security disability insurance rolls from mid-1980 to mid-1981 had median monthly incomes of less than $500 if they were unmarried and less than $1,300 if they were married. These median monthly income levels, which include the income of a spouse and minor children if present, are roughly half those of the noninstitutionalized population aged 25-64. Social security benefits are the most important source of income for disabled workers and their families: They account for 40 percent of the total family income of married disabled workers and 65 percent of the total income of unmarried disabled workers. Social security benefits provide at least half of all income for more than 80 percent of unmarried disabled-worker beneficiaries and for 50 percent of the married beneficiaries. For married disabled-worker beneficiaries, earnings of the spouse are the second most important income source. Spousal earnings account for 28 percent of total income. Pensions and asset income each account for about 10 percent of total income for these married beneficiaries. Earnings are not an important source of income for unmarried disabled-worker beneficiaries for whom they amount to only about 3 percent of total income. Pensions, asset income, and public transfers each account for about 10 percent of total income of the unmarried beneficiaries.  相似文献
