The purpose of this preliminary study was to examine associations between leaving home to engage in bingo or gambling activity and indices of physical and mental health and social support among a representative community cohort of 1016 elderly people. Cross-sectional and longitudinal data gathered from a prospective epidemiological study in a rural, low socio-economic status, area of Pennsylvania was employed. The cohort had a mean age of 78.8 (SD = 5.1) (range 71–97) and participated in three consecutive biennial waves of data collection. Nearly half (47.7) of the cohort reported gambling. To predict gambling, the independent variables included age, sex, education, employment, social support, depressive symptoms, self-rated health, alcohol use, cigarette use, and cognitive functioning. In cross-sectional, univariate analyses, gambling was associated with younger age, sex (male), fewer years of education, greater social support, lower depression scores, better self-rated health, alcohol use in the past year, and higher cognitive functioning. In a cross-sectional multiple regression model, younger age, greater social support, and alcohol use in the past year remain strongly and independently associated with gambling activity. Longitudinally, age, sex, social support, alcohol use, and gambling are predictive of future gambling activity. The results revealed that gambling may offer a forum of social support to older adults who are often isolated as they age.  相似文献

Utilizing Third-Party Inspections for Preventing Major Chemical Accidents   总被引:1,自引:0,他引:1  
This paper proposes using certified third parties, coupled with Model Risk Management Programs (Model RMPs), to implement EPA's Proposed Rule on the prevention of chemical accidental releases. We concentrate on the insurance aspects of this third-party approach and show that it could enable insurers to more cost-effectively provide coverage against the risks of chemical accidental releases. The third-party approach may also signal the facility's safety and reduce the enforcement costs of regulations.  相似文献

Field work with the computer: Criteria for assessing systems   总被引:1,自引:0,他引:1  
Computers, both large and small, can be of great assistance to a field worker. This assistance falls mainly in the area of relieving the field worker from tedious mechanical phases such as typing, sorting, and retrieving information. An examination of field work methods identifies issues and problems which must be addressed by any system for undertaking field work. A rationale for a loose and inclusive (as opposed to an exhaustive and mutually exclusive) coding system is presented. Efficiency, confidentiality, data reduction, and flexibility of testing propositions are discussed as criteria for assessing any system which facilitates field work. The paper concludes by contrasting the methods previously used to collect data, reduce its bulk, code, and retrieve information with what is possible with today's computer hardware and software, and with what will be possible in the near future.We wish to thank Peter Conrad, Susan LeBailly, and the anonymous reviewer of this article for their comments and suggestions.  相似文献

Following recent developments concerning individual differences in nonverbal social skills, the present study examined the inter-relationships of several standardized measures of nonverbal skills and personality. Particular attention was given to the concept of self-monitoring, thought to be a skill central to social interaction. Based on previous research which suggested that self-monitoring, as measured by the Self-Monitoring Scale (SMS), is a multidimensional construct, it was hypothesized that self-monitoring may actually be comprised of a number of more basic social skills. Correlations between standardized measures of basic social skills and three factors obtained from factor analysis of the SMS (Briggs, Cheek, & Buss, 1980) supported this conception. The elements of self-monitoring appear to be “charisma,” “performance,” and “social sensitivity.”  相似文献

Variable selection for multivariate nonparametric regression is an important, yet challenging, problem due, in part, to the infinite dimensionality of the function space. An ideal selection procedure should be automatic, stable, easy to use, and have desirable asymptotic properties. In particular, we define a selection procedure to be nonparametric oracle (np-oracle) if it consistently selects the correct subset of predictors and at the same time estimates the smooth surface at the optimal nonparametric rate, as the sample size goes to infinity. In this paper, we propose a model selection procedure for nonparametric models, and explore the conditions under which the new method enjoys the aforementioned properties. Developed in the framework of smoothing spline ANOVA, our estimator is obtained via solving a regularization problem with a novel adaptive penalty on the sum of functional component norms. Theoretical properties of the new estimator are established. Additionally, numerous simulated and real examples further demonstrate that the new approach substantially outperforms other existing methods in the finite sample setting.  相似文献

As new and more effective human reproductive genetic technologies (RGTs) rapidly develop, religious voices remain an important part of public discussion about the moral standing of such technologies. Here, we compare how individuals from different religious traditions evaluate disease RGTs (detecting genetic diseases in vitro) when compared to enhancement RGTs, allowing parents to select features of a child. Findings are gleaned from analysis of 270 interviews with individuals from 23 Christian, Muslim, and Jewish religious organizations, with supporting data from a national survey of more than 10,000 Americans. We find that respondents engage in clearly defined discursive moral reasoning to evaluate the propriety of disease RGTs while moral intuitions manifest themselves in responses to enhancement RGTs. We argue that schemas provide resources for moral discourses while also shaping moral intuitions expressed through emotions. Our results have implications for how religious people respond to new technologies when their institutional and denominational structures do not have readily discernable moral frameworks to guide responses.  相似文献
