Recent research has usefully documented the contribution that nonprofit organizations make to social capital and to the economic and political development it seems to foster. Because of a gross lack of basic comparative data, however, the question of what it is that allows such organizations to develop remains far from settled. This article seeks to remedy this by testing five existing theories of the nonprofit sector against data assembled on eight countries as part of the Johns Hopkins Comparative Nonprofit Sector Project. The five theories are: (a) government failure/market failure theory; (b) supply-side theory; (c) trust theories; (d) welfare state theory; and (e) interdependence theory. The article finds none of these theories adequate to explain the variations among countries in either the size, the composition, or the financing of the nonprofit sector. On this basis it suggests a new theoretical approach to explaining patterns of nonprofit development among countries—the social origins approach—which focuses on broader social, political, and economic relationships. Using this theory, the article identifies four routes of third-sector development (the liberal, the social democratic, the corporatist, and the statist), each associated with a particular constellation of class relationships and pattern of state-society relations. The article then tests this theory against the eight-country data and finds that it helps make sense of anomalies left unexplained by the prevailing theories. 相似文献

The Vulnerable Infants Program of Rhode Island is a care coordination program to promote permanency for substance-exposed infants by addressing parental needs and increasing collaboration among social service agencies. Over the first four years of the program, there was a decrease in time spent in the newborn nursery beyond medical necessity and identification of permanent placements by 12 months for 84% of infants, with the majority of infants (78%) placed with biological parents or relatives. 相似文献

The financial sector is playing a more central role in agriculture. This article analyzes the external provision of finance for farmers in Britain and the Irish Republic, drawing principally on interviews with bankers and specialist providers of agricultural finance. The development of farm credit institutions in the two countries and their subsequent commercialization is discussed. Agriculture is commercially attractive to lenders as part of a balanced portfolio because of its stable, low risk character. Credit selectivity is confirmed as a feature of lender behaviour, although its consequences are likely to be more far reaching in Ireland. Lenders' perceptions of the financial sophistication of farmers is assessed, the more financially sophisticated farmer being more receptive to the logic of the financial sector and hence a more attractive customer. An emphasis on tax avoidance can lead farmers into irrational borrowing decisions. Larger farmers are better placed to take advantage of lending opportunities and new financial instruments. 相似文献

Through an analysis of popular posts Tibetans shared over the social media application WeChat in 2013 and 2014 and offline discussions about them, this paper shows how Tibetans living in and traveling through Xining City practiced and performed their ethnic identity in the face of perceived harassment. Through their viral posts, they created a cyber-community that contributed to Tibetan ethnic group formation when Tibetans interpreted their ethnic identity as the basis for unjust treatment by the Chinese state and private Han individuals. In online posts the Han are portrayed as harassing Tibetans after terror attacks across China, violating minzu rights, denigrating Tibetan culture and territory, and denying Tibetans equal footing as modern compatriots. Social media are changing the ‘representational politics’ of Tibetan ethnicity, altering participation in the representation of the Tibetan ethnic group. Still, online discourse remains subject to constraints; private offline discussions remain important fora of opinion exchange. 相似文献

While multiple studies have documented shifting educational gradients in HIV prevalence, less attention has been given to the effect of school participation and academic skills on infection during adolescence. Using the Malawi Schooling and Adolescent Study, a longitudinal survey that followed 2,649 young people aged 14–17 at baseline from 2007 to 2013, we estimate the effect of three education variables: school enrolment, grade attainment, and academic skills—numeracy and Chichewa literacy—on herpes simplex virus type 2 (HSV-2) and HIV incidence using interval-censored survival analysis. We find that grade attainment is significantly associated with lower rates of both HSV-2 and HIV among girls, and is negatively associated with HSV-2 but not HIV among boys. School enrolment and academic skills are not significantly associated with sexually transmitted infections (STIs) for boys or girls in our final models. Efforts to encourage school progression in high-prevalence settings in sub-Saharan Africa could well reduce, or at least postpone, acquisition of STIs. 相似文献

A nationwide research program on the performance of American industry, sponsored by the Alfred P. Sloan Foundation, now involves scores of faculty researchers and more than 100 graduate students at several American universities. Ten research centers have been established, and each one is dedicated to the study of a particular industry. An eleventh center is carrying out research on problems that cut across these industries. It is expected that the Sloan Industry Studies program will make useful contributions to the performance of the industries themselves, to policymaking at all levels of government, and to the development of interdisciplinary research communities within the universities. 相似文献

Johansson A Grant JE Kim SW Odlaug BL Götestam KG 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》2009,25(1):67-92
This article is a critical review of risk factors for pathological gambling categorized by demographics, physiological and
biological factors, cognitive distortions, comorbidity and concurrent symptoms, and personality symptoms and characteristics.
There is also a varia section (availability, parents playing, sensory characteristics, schedules of reinforcement, age of
onset, and playing duration). The review found very few well established risk factors for pathological gambling (i.e. more
than two studies to support the conclusions). Well established risk factors included demographic variables (age, gender),
cognitive distortions (erroneous perceptions, illusion of control), sensory characteristics, schedules of reinforcement, comorbid
disorders (OCD, drug abuse), and delinquency/illegal acts. An understanding of risk factors for pathological gambling should
enhance prevention and treatment approaches. 相似文献

We consider situations in which externally observable characteristics allow experts to quickly categorize individual households as likely or unlikely to contain a member of a rare target population. This classification can form the basis of disproportionate stratified sampling such that households classified as "unlikely" are sampled at a lower rate than those classified as "likely," thereby reducing screening costs. Design weights account for this approach and allow unbiased estimates for the target population.We demonstrate that with sensitivity and specificity of expert classification at least 70%, and ideally at least 80%, our approach can economically increase effective sample size for a rare population. We develop heuristics for implementing this approach and demonstrate that sensitivity drives design effects and screening costs whereas specificity only drives the latter. We demonstrate that the potential gains from this approach increase as the target population becomes rarer. We further show that for most applications, unlikely strata should be sampled at 1/6 to ? the rate of likely strata.This approach was applied to a survey of Cambodian immigrants in which the 82% of households rated "unlikely" were sampled at ? the rate as "likely" households, reducing screening from 9.4 to 4.0 approaches per complete. Sensitivity and specificity were 86% and 91% respectively. Weighted estimation had a design effect of 1.26 so screening costs per effective sample size were reduced 47%. We also note that in this instance, expert classification appeared to be uncorrelated with survey outcomes of interest among eligibles. 相似文献
