Tucker DJ 《The Social service review》1980,54(1):13-30
This study investigates the validity of the assumption that coordination and citizen participation are related inversely and, thus, are incompatible as features in the same social service reform strategy. Seventeen social service organizations situated in the same urban area were studied. Data were obtained by structured interview. The concepts of coordination and citizen participation were operationalized by means of scales. The findings support the validity of the assumption noted above. Although interpretations of the findings can be provided, they are post-factum. This implies a need for explanatory research which might be guided by theories of community power structure and of organizational behavior. 相似文献

Contrary to the impression left by historians, neither welfare expansion nor welfare reform died in the 1950s. Even conservatives believed in the necessity of federal spending for welfare. Disagreements came over the proper ways to spend federal money. The Eisenhower administration propagated a rehabilitation approach in an attempt to use federal money to end individual, state, and local dependence on the federal government. The administration's 1954 social security and vocational rehabilitation laws reflected this approach. Bureaucrats in the Department of Health, Education, and Welfare, working with a Democratic Congress, managed to extend the 1954 laws into a major expansion of federal power, as the passage of disability insurance in 1956 demonstrated. Institutional continuity, not heroic individual effort, provided the dynamic for welfare reform in the 1950s. 相似文献

Public policy decisions in health are increasingly difficult and expensive. Although there will never be enough information available, private foundations can help to bridge the most important gaps in knowledge. Larger foundations may also wish to respond to those who doubt the value of foundation activities. This article reviews the experiences over the past eight years of The Robert Wood Johnson Foundation in employing evaluation and related social research procedures in the planning and implementation of a major philanthropic effort to improve the health and medical care of Americans. Discussed are the still evolving Foundation evaluation framework, the unanticipated problems in undertaking specific evaluations, and the substantive findings of some of the studies. 相似文献

The increasing need for business to monitor the social dimensions of its environment and, hopefully make some forecasts of future trends has met with some constructive response from academics and consultants although not as yet on a very liberal scale. The published literature does not indicate to what extent companies in general attemp social forecasting and, where they do, the degree of integration which exists within their corporate planning systems. The authors, therefore, decided to survey a sample of British organizations to see if they could shed some light on these issues and thereby add some information to the excellent accounts of individual cases of social forecasting in, they suspect, the more advanced and atypical companies. The survey suggests a general picture of: awareness of the value of social forecasting; fairly widespread ignorance of the techniques which do exist, primitive though these may largely be; successful integration of social forecasting into the corporate planning systems of a substantial number of organizations but not in the majority. 相似文献

A survey of perceived morbidity was carried out in rural population in eight villages and four wards of Saoner town, covering a total population of 8,876. The nature of illness was assessed by weekly visits to the families. History regarding treatment taken for disease and its source was taken. The overall incidence of perceived morbidity was 176.35 spells of sickness per 1000 population per month. Health care agency was contacted for 36.7 per cent spells of sickness. Utilisation of health services was found to be affected significantly by factors like age (chi 2 = 138.36), literacy (chi 2 = 14.123), type of occupation (chi 2 = 433.74), nature of illness (chi 2 = 83.578) and accessibility of health services. A health behaviour model of the population has also been discussed in this paper. 相似文献

"One can often gain insight into the aetiology of a disease by relating mortality rates in different areas to explanatory variables. Multiple regression techniques are usually employed, but unweighted least squares may be inappropriate if the areas vary in population size. Also, a fully weighted regression, with weights inversely proportional to binomial sampling variances, is usually too extreme. This paper proposes an intermediate solution via maximum likelihood which takes account of three sources of variation in death rates: sampling error, explanatory variables and unexplained differences between areas. The method is also adapted for logit (death rates), standardized mortality ratios (SMRs) and log (SMRs). Two [United Kingdom] examples are presented." 相似文献

Interest in the efficiency or inefficiency of non-profit firms has spawned research on the administrative costs of Blue Cross and Blue Shield plans. Relying on plausible implications of the property rights theory of the firm, both Blair, Ginsburg, and Vogel (1975) and Vogel (1977) noted some evidence of inefficiency in these firms. Our analysis, however, utilizing their models and more recent data, reveals little convincing evidence for the view that Blue Shield plans are inefficient. 相似文献
