Growth has for long been accepted as one of the major objectives of most people. Recently it has been challenged from a number of directions and the challengers have been counter-challenged. The inadequacy of scientific evidence lays the field open for much controversy, but the questions which have been brought into prominence are of great importance and demand answers. These answers in turn require knowledge associated with many branches of the physical, biological and social sciences. The techniques of operational research can be and are being used to assemble and blend the evidence. These techniques can also show up the gaps and the obstacles in the path to progress.Slightly revised version of a paper presented at the Sixth Conference of the International Federation of Operations Research Societies, Dublin, Ireland, August 1972. 相似文献

What type of oversight should states exercise over local units in order to prevent fiscal crises? This article discusses a sequence of three best practices that some states use to prevent fiscal emergencies. They first monitor local government finances to predict fiscal distress. After detecting signs of fiscal distress, states actively assist local units in ameliorating the problem. Finally, assistance notwithstanding, if a situation becomes grave, states require local units to take strong remedial measures, including increasing taxes and reducing expenditures. 相似文献

Few studies have examined risk factors of childhood and early adolescent depressive symptomatology trajectories. This study
examined self-report depressive symptomatology across a 6-year time period from 2nd to 8th grade to identify latent groups
of individuals with similar patterns of depressive phenomena in a sample of 951 children (440 girls, 511 boys). Analyses,
using semiparametric group modeling (SGM), identified 5 trajectory groups for girls and boys: low depressed stables, low depressed
risers, mildly depressed stables, moderately depressed changers, and moderately depressed risers. Individual risk factors,
with the exception of shy/withdrawn behavior, were significantly different across trajectory group membership for boys and
girls, as was low-income status for boys. Boys in the low depressed and mildly depressed stable trajectory groups had significantly
higher levels of antisocial behavior, attention problems, and lower social competency compared to girls in similar groups.
These results suggest that universal prevention programs implemented in early elementary school that target selected risk
factors may be helpful in reducing future adolescent mental health problems, specifically depressive symptomatology. 相似文献

Social capital has attracted increasing attention in recent years. We use county-level and individual survey data to study how Wal-Mart affects social capital. Estimates using several proxies for social capital—such as club membership, religious activity, time with friends, and other measures—do not support the thesis that “Wal-Mart destroys communities” by reducing social capital. We measure exposure to Wal-Mart two ways: Wal-Marts per 10,000 residents and Wal-Marts per 10,000 residents aggregated over the years since 1979 to capture a more cumulative “Wal-Mart Effect.” We find that the coefficients on Wal-Mart’s presence are statistically insignificant in most specifications. 相似文献

Environmental markets have several institutional features that provide a new context for the use of auctions and that have not been studied previously. This paper reports on laboratory experiments testing three auction forms—uniform and discriminatory price sealed‐bid auctions and an ascending clock auction. We test the ability of subjects to tacitly or explicitly collude in order to maximize profits. Our main result is that the discriminatory and uniform price auctions produce greater revenues than the clock auction, both with and without explicit communication. The clock appears to facilitate successful collusion, both because of its sequential structure and because it allows bidders to focus on one dimension of cooperation (quantity) rather than two (price and quantity).© 2009 by the Association for Public Policy Analysis and Management. 相似文献

Based on research carried out by INTRAC (International NGO Training & Research Centre) in 2006–2007 in four countries of Central Asia for Oxfam–Novib, the article investigates NGO networks and their international links in the context of current theory on civil society and global civil society. Three case studies of NGOs working in service delivery, community development and free media are examined to show the diversity of aims and the potential and challenges of networking in the region. Civil society advocacy at national and international levels is analysed with a fourth case study on the campaign conducted in Kyrgyzstan against joining the World Bank's Highly Indebted Poor Countries programme. This example shows a more radical, alternative mode of civil society activism. The article emphasizes the importance of national- and regional-level networking and poses the question of whether NGOs in Central Asia can shift from their current positions on the periphery of global movements and debates. 相似文献
