This article describes three ideal-typical cultures of grant-making constructed in the light of data from an exploratory study of British foundations. These three cultures, representing the values and assumptions which inform the way in which foundations approach the task of making grants, have very different implications for the resources required by foundations and for organisational processes and procedures. The article goes on to discuss some of the organisational and management dilemmas of British grant-making foundations. Five key source of management difficulty in the grant-giving foundation are identified. First, grant-giving foundations face particular difficulties in identifying and assessing the relevance of their priorities; these difficulties stem from the nature of grant-giving and the foundation's relationship with its ‘customer-suppliers’. Second, grant-giving foundations must manage within the constraints imposed by limited choice of and time available from trustees. Third, grant-giving foundations must manage the potential tension between control by donors and trustees. Fourth, grant-giving foundations must work within financial and time constraints. Fifth, the management of grant-giving foundations may be further hampered by lack of adequate feedback. In this article, particular attention is paid to the first three difficulties.  相似文献

1. Specifying a model to guide research projects helps clarify the study, permits several investigators to work in a coordinated fashion on large projects, and facilitates comparisons across studies. 2. This model is composed of seven domains and indicates some of the hypothesized relationships between domains. Adapting the model to individual studies may result in a different number of domains and in the specification of other hypothesized relationships. 3. When possible, researchers should make use of minimum data sets to enhance the comprehensiveness and generalizability of their research.  相似文献

Average human life expectancies for the U.S. resident population are calculated using tabulated population and survival rate data. These life expectancies are recalculated assuming elimination of various types of motor vehicle fatalities using Fatal Accident Reporting System (FARS) data. The differences between the original and recalculated values provide estimates of life expectancy reductions due to the motor vehicle fatalities. These estimates are combined with prior work relating the likelihood of an occupant fatality to car mass, so that reductions in life expectancy are determined as a function of car mass. The estimates of life expectancy reductions are also used to determine the effect of seat belt use on life expectancy. The estimates, which are based on data for 1978, assume that survival rates remain unchanged. Estimates of the changes in life expectancy associated with switching from a large (1800 kg) car to a small (900 kg) car, and switching from not using to using a seat belt are presented as functions of the age at which an individual makes the switch.  相似文献

Lipsky's Street-level Bureaucracy (Russell Sage Foundation, New York, 1980 Lipsky, M. 1980. Street-level Bureaucracy: The Dilemmas of Individuals in Public Service, New York: Russell Sage Foundation.  [Google Scholar]) has exerted a strong influence on the study of public service organisations. There has been a growing interest in using this perspective to understand the organisational context of social work and Musil et al.'s article in the EJSW (2004, ‘Do social workers avoid the dilemmas of work with clients?’, European Journal of Social Work, vol. 7, no. 3, pp. 305–319) reflects this interest. Musil et al. argue that it is possible to identify two forms of practitioner response to the constraints of street-level bureaucracies: adapting working practices in ways that disadvantage service users or challenging working conditions in order to achieve more professionally acceptable practice. Their contribution to the debate is helpful, particularly with regard to their identification of responses by practitioners that seek to advance the interests of service users. However, we view their approach as constrained by lack of consideration of the construction of social work roles within particular street-level bureaucracies. We suggest that Lipsky's work should be approached as a tentative analytic framework, rather than as a fixed model and we argue that a productive approach to research on social workers as street-level bureaucrats is conjunctural analysis. Such analysis examines the contexts, circumstances and statuses of practitioners and how these factors shape the specific forms of street-level practice that operate in particular organisational settings. We illustrate this in our discussion of the factors that are likely to have had a bearing on the two practice settings used as case studies by Musil et al.  相似文献

In this paper we introduce a new family of robust estimators for ARMA models. These estimators are defined by replacing the residual sample autocovariances in the least squares equations by autocovariances based on ranks. The asymptotic normality of the proposed estimators is provided. The efficiency and robustness properties of these estimators are studied. An adequate choice of the score functions gives estimators which have high efficiency under normality and robustness in the presence of outliers. The score functions can also be chosen so that the resulting estimators are asymptotically as efficient as the maximum likelihood estimators for a given distribution.  相似文献

Abstract

“Women who have sex with women” or WSW have unique perspectives within the LBGTQ spectrum. The purpose of this study included documenting perceptions, feelings, and experiences among WSW. Thirty-seven women participated in six focus groups, ages ranged from 20–64 years. Responses were transcribed and thematically coded. Four themes emerged as influencing factors: shame and fear, community, gender roles, and normalcy. Each major theme produced minor themes providing a context within major themes. Results offer valuable insights that can assist community members, health professionals, and scientists to better appraise the disparities and stigma impacting social and emotional well-being among WSW.  相似文献
