Surprisingly little research has sought to explain differential participation after recruitment into social movement organizations (SMOs). This study examines the influence of several sets of predictors on participation by members of a national organization in the antihunger movement. The findings highlight the importance of incentive, ideological, and microstructural factors for differential participation and suggest that favorable perceptions of SMOs also promote participation. Final remarks address the implications of the findings for the social movement and voluntary organization literatures.  相似文献

The incidence of pregnancy during adolescence has escalated dramatically in recent years, with an estimated half a million infants born to teenagers each year in the United States. A disproportionately high amount of child abuse and/or neglect is encountered among adolescent parents, underscoring the need for an effective intervention strategy. Short-term psychotherapy may be beneficial in these cases for forging a therapeutic alliance expeditiously and rigorously challenging the patient's resistance. The case described involves alleged abuse by a 16-year-old mother. An intervention was designed to clarify the allegations surrounding the abusive incident, help the mother confront episodes of loss in her own life and overcome feelings of hopelessness engendered by separation from her infant.  相似文献

Approximations of the Bayesian estimators of the survival function based on the censored data of the log-logistic distribution are obtained under squared-error and log-odds squared-error loss functions. A numerical example is presented. Through a Monte Carlo simulation study, the behavior of the approximations found by Tierney & Kadane and Lindley are compared with a method suggested by Weiss & Howlader.  相似文献

THE SOLUTION-ORIENTED GENOGRAM: A COLLABORATIVE APPROACH   总被引:1,自引:0,他引:1  
Developed primarily by Bowenian intergenerational therapists, genograms have evolved into largely atheoretical tools used by many therapists. Given that constructivist-based therapies have become the most popular genre of contemporary family therapies (Sprenkle & Piercy, 1992), the author examines how genograms can be used to augment a solution-oriented approach. Specific interventions, case examples, and potential problems associated with such an approach are discussed, along with potential implications for family-of-origin work.  相似文献

This paper compares legal approaches to foundations in six economically well-developed democracies (USA, England and Wales, Germany, Austria, France and the Netherlands). ‘Foundations’ refers to ‘non-governmental, non-membership, organisations, recognised as a legal category with a purpose in the general interest’. This covers the common field of the common law's charity and the civil law's foundation as a legal person. The countries organise public supervision of foundations in very different ways. Mostly there is governmental involvement or involvement of an independent body in the establishment and governmental supervision of foundations in action. In a few cases, the supervisory power—concerning the foundations' activities, not their establishment—is with judicial authorities. Access to information of foundations (registration) and possible requests for sanctions by interested parties are also rather different. Not all rules are in accordance with the freedom of organisation and some are less desirable. The conclusion is that a balance between the freedom of the foundation (board), the protection of the public order and the protection of the interests of others can be found in a system with systematic supervision at the establishment- and later practice—by governmental or independent authorities or in a system with good registration and incidental supervision by judicial authorities, also at the request of interested parties. Both have their advantages and disadvantages.  相似文献

The effects of question order on respondents' ratings of general and specific aspects of community life were assessed using data from separate mail surveys in Montana and Pennsylvania, The samples differed in locale, composition, and size and the relevant questions varied in number, format, and specific focus. Nevertheless, for both data sets the general question was more likely to be answered and more likely to receive positive responses when it was asked after—rather than before—the specific questions. There was some indication that carryover from the specific items to the general question responses were somewhat greater for those questions asked most recently and less for those asked earlier. Implications of these findings are discussed.  相似文献
