Pivotal in HIV/STD intervention and prevention is how individuals perceive risk. This article discusses how ethnotheory can be used to understand the underpinnings of risk perception from the subject's perspective. Ethnotheory's theoretical and methodological character extends present models used to explain sex-related HIV behaviors and provides insights into risk perception useful for the development of effective intervention strategies. Four detailed ethnographic excerpts from low-income African American and Mexican American men and women illustrate how people form perceptions of risk and how information gained through ethnotheory is useful in the design of culturally relevant interventions. 相似文献

The distress of 52 parents with a technology-dependent child at home is measured using a standardized psychological inventory. Fifty-eight percent of these parents report enough symptoms to classify them as needing psychiatric intervention. Cost savings to third-party payers are accelerating the trend toward home care (rather than institutionalized care). Yet, these findings point to an underestimated cost to families in terms of parents' psychological well-being. One factor associated with less distress for mothers is having services reimbursed through the Medicaid Model Waiver Program, which provides a comprehensive plan for home care services. In contrast, services reimbursed by private third-party payers are more variable, placing greater financial strain and uncertainty on parents, which is associated with greater psychological distress. These results suggest the need for further study of the long-term impact on parents caring for technology-dependent children at home.Reprint requests to Barbara J.

Conflict situations were studied as indicators of children's socio-cognitive knowledge and the transmission of values in relation to negotiation. Concepts and paradigms from studies of requests were combined with those from studies of refusals. Puppets were used to create situations that varied (a) as to whether the child makes a request and encounters opposition (requests) or receives a request and offers opposition (refusals), (b) whether the adult offers or does not offer a reason. Children aged 3–5 years (Sample 1, N = 24; Sample 2, N = 24) were encouraged to make a series of attempts at resolving the conflict. Their responses were scored for the level of politeness or strategic skill shown. Request situations elicited higher levels of politeness and strategic skill than did refusal situations. In contrast to disputes in which the other party did not use reasons, the use of a reason by the other party elicited higher level strategies and, when the children were refusing, greater politeness. Some children were able to improve on their first attempt. The improvement was most marked when children were requesting and the adult gave a reason. 相似文献

MORAL MESSAGES: THE RELATIVE INFLUENCE OF DENOMINATION ON THE RELIGIOSITY-ALCOHOL RELATIONSHIP 总被引:2,自引:0,他引:2
This article examines the use and misuse of alcohol across religious denominations. After controlling for standard sociodemographic variables, we find that the impact of religiosity on alcohol use is greatest among those denominations taking a strong stand against its consumption, mainly because religion constitutes a significant reference group for members. We also find that religiosity fails to influence misuse, and discuss the possible reasons for this result. 相似文献

The authors describe a random-effects fertility model based upon the assumption that the menstrual cycle viability probability varies from couple to couple according to a beta distribution. An EM algorithm is used to fit the model. The proposed estimating procedure is fully expandable to allow covariate effects on the beta variate. The method can be applied generally whenever dependency among Bernoulli trials is induced by a susceptibility state and the outcomes can be observed only in the aggregate. Based upon data from a cohort of 221 couples with no known fertility problems who were attempting pregnancy, cycle viability was found to be heterogeneous among couples. Stratification on the presence or absence of prenatal exposure of the woman to her mother's cigarette smoking revealed a statistically significant difference in the two-cycle viability distributions. Differences are discussed in the interpretation of the beta model compared to the marginal approach based upon generalized estimating equations. 相似文献

This paper considers the estimation of multivariate random effects that are measured with error, but for which there are no replications. Using structural simplification of the correlation of the data, separate estimates are generated for the covariance of the random effects and the covariance of the error. An estimator of the random effects based on a truncated eigen structure is defined, and matrix mean squared error and its trace (risk) are analyzed, with comparison to the maximum likelihood estimator (m.l.e) and also to the Stein-like estimator of Efron and Morris (1972). It is shown that the estimator has risk which is smaller than the risk of the maximum likelihood estimator and the Efron-Morris estimator in most cases. 相似文献

A Bayesian method is proposed for estimating the cell probabilities of several multinomial distributions. Parameters of different distributions are taken to be a priori exchangeable. The prior specification is based upon mixtures of a hierarchical distribution, referred to as the multivariate “Dirichlet-Dirichlet” distribution. The analysis is facilitated by a multinomial approximation relating to the multinomial-Dirichlet distribution. The posterior estimates depend upon measures of entropy for the various distributions and shrink the individual observed proportions towards values obtained by pooling the data across the distributions. As well as incorporating prior information they are particularly useful when some of the cell frequencies are zero. We use them to investigate a numerical classification of males of various vocations, according to cause of death. 相似文献
