Bingo is one of the most popular and most accepted forms of gambling in the United States today. Yet, despite its popularity, many bingo players are not completely comfortable with the moral rightness of their actions. This participant observation and interview study spanning a 5 year period shows how bingo players use superstitious strategies, such as feelings, hunches and psi, attitudes, and luck to neutralize their marginally deviant behaviors. 相似文献

The problems that people experience in social roles can be regarded as either causes or consequences of psychological symptoms. To reflect one of these possibilities, Pearlin et al. (1981) developed measures of "role strains" which are considered sources of psychopathology. To reflect the other position, Dohrenwend et al. (1981) constructed measures of "role functioning" which are seen as consequences of psychopathology. We show that the measures developed by these two teams of investigators are similar in content and show substantial empirical overlap despite the different meanings attributed to them. In an effort to understand whether these highly correlated measures assess, "role strain" or "role functioning," we conduct an exploratory analysis of marital and housework role problems, using a small panel sample of New York City residents. Specifically, we use instrumental variables to identify reciprocal effects between psychological distress and each role area. We find that the relationship between housework role problems and distress is more consistent with Pearlin et al.'s interpretation, whereas the relationship between marital problems and distress is more consistent with that of Dohrenwend et al. Investigators interested in measuring either role strain or role functioning must bear in mind the strong possibility of contamination from the other construct. 相似文献

A recent American survey of attitudes toward societal multiculturalism vs. assimilation has found surprisingly widespread support for maintaining heritage cultures not only among immigrant minority groups but also among most subsamples of majority host groups, black and white. Working-class whites are the one exception. This pilot study explores the same attitude domain in a contrasting European setting. Randomly selected samples of middle- and working-class families (a mother, father, and teenage son or daughter) from a small city in France were interviewed. As a group, they were neutral to slightly favorable to immigrants maintaining heritage cultures and languages rather than losing them through assimilation. On measures of attitudes toward specific immigrant groups, there were marked intergroup dyfferunces with Maghrebian Arabs rated leist favorably and Southeast Asians, the model immigrants, most favorably. Comparisons of subgroups of respondents who varied in terms of (a) political left-right orientation, (b) social class standing, (c) degree of religiosity, and (d) generational level provide the base for a more general discussion of cultural assimilation and multiculturalism. 相似文献

This paper aims at statistical identification of the relationship between the parity of farming families and the area of the farm and the role this variable plays among variables describing the model of families' parity. To reach this objective results of a questionnaire survey were used, one performed among the group of individual farmers' families keeping agricultural accounting in 1985. The analysis covered 1291 rural farming couples who married in the years 1920-1984. According to the results obtained, the thesis posed by W. Stys with regard to positive relationships between parity in a family and the farm's area only relates to marriages entered into between 1920-1964. In single five-year marriage cohorts, a change of shape of this relationship was observed. It took the shape of a parabolic function or polynomial of the third order. The research results showed that in marriage cohorts with finished fertility, variable area of the farm turned out to be almost insignificant in explaining changes in the number of live born children compared to other demographic factors, especially cultural and demographic ones. 相似文献

Tensions in the relationship between boards and staff are a common feature of voluntary and nonprofit agencies which deliver services. Many of the difficulties reflect lack of clarity about the power of boards. The author describes three models of governance: traditional, membership, and entrepreneurial. Each model has different implications for the power of a board in relation to staff. Practitioners in nonprofit service delivering agencies in the UK have found the models to be a useful tool for explaining the practical difficulties they experience. 相似文献

The benefits of providing a separate accounting for non-profit organisations in the financial accounts of the United States are discussed. At present, national economic accounts in the US include non-profit organisations with individuals in the household sector; separate information on the financial activity of non-profit institutions until now has not been available. In this paper, aggregate statistics from federal government tax-exempt filings for non-profit institutions are put into a US flow-of-funds framework. The data for the 1982–1988 period indicate that non-profit institutions accounted for a significant and growing proportion of assets of the household sector in the United States. Their liabilities were also a surprisingly large share of the household sector total. Moreover, funds supplied by the non-profit sector for investment were in some years comparable to funds made available by several important groups of non-depository financial intermediaries. Separate accounting for non-profit organisations within national economic accounts would be likely to reveal an important channel for investment financing in the United States and would significantly improve our ability to measure and analyse the financial activity of individuals by allowing for a purer household sector.The analysis and conclusions set forth are those of the authors and do not necessarily indicate concurrence by Salomon Brothers, the Board of Governors, Federal Reserve Banks or other members of their staffs. 相似文献

Changes occurring in health care demand that physicians expand their professional knowledge and skills beyond the medical and behavioral sciences. Subjects absent from traditional medical education curricula, such as the economics and politics of health care, practice management, and leadership of professional organizations, will become important competencies, particularly for physicians who serve in management roles. Because physicians occupy a central role in planning and allocating medical care services and other health care resources, they must be better prepared to work with other health care professionals to create a new civilization, even if this means leaving the cloistered domain of "physician land" to serve as interface professionals between the delivery of medical services and the management of health care. Our research findings and conclusions strongly suggest that economic, management, and leadership competencies need to be incorporated into the professional development of physicians, especially in postgraduate and continuing education curricula. 相似文献

An experiment was conducted to assess the effect of using "markall that apply" question instructions on survey reporting aspart of the field test for the Second Follow-up of the NationalEducation Longitudinal Study of 1988 Eighth Graders (NELS:88).Mark-all-that-apply instructions were compared with instructionsasking respondents to indicate "yes" or "no" to each responseoption on responses to three items dispersed throughout thequestionnaire and consisting of different topics and numbersof response options. For the three items, significantly fewerresponse options were selected with the mark-all-that-applyinstructions than with the yes/no instructions, but becauseexternal validity criteria were not available, overreportingto the yes/no instructions cannot be ruled out. Instructiondependentprimacy effects, predicted under the hypothesis that respondentswould engage in more superficial processing when given the mark-all-that-applyinstructions, were not found. 相似文献
