We consider situations in which externally observable characteristics allow experts to quickly categorize individual households as likely or unlikely to contain a member of a rare target population. This classification can form the basis of disproportionate stratified sampling such that households classified as "unlikely" are sampled at a lower rate than those classified as "likely," thereby reducing screening costs. Design weights account for this approach and allow unbiased estimates for the target population.We demonstrate that with sensitivity and specificity of expert classification at least 70%, and ideally at least 80%, our approach can economically increase effective sample size for a rare population. We develop heuristics for implementing this approach and demonstrate that sensitivity drives design effects and screening costs whereas specificity only drives the latter. We demonstrate that the potential gains from this approach increase as the target population becomes rarer. We further show that for most applications, unlikely strata should be sampled at 1/6 to ? the rate of likely strata.This approach was applied to a survey of Cambodian immigrants in which the 82% of households rated "unlikely" were sampled at ? the rate as "likely" households, reducing screening from 9.4 to 4.0 approaches per complete. Sensitivity and specificity were 86% and 91% respectively. Weighted estimation had a design effect of 1.26 so screening costs per effective sample size were reduced 47%. We also note that in this instance, expert classification appeared to be uncorrelated with survey outcomes of interest among eligibles.  相似文献

Articles by women scholars and proportions of articles focused on gender have increased steadily in major sociology journals since 1974. Women are more heavily represented as journal authors than as members of graduate-program departments, the institutional bases where most published work originates. We consider whether funding might account for these patterns by examining acknowledgement of support in published articles. We find no significant relationships among author gender, article topic, and notation of internal funding. Male-authored articles focused on nongender topics acknowledge external funding significantly more often than women-authored works and articles focused on gender written by women or men. Funding patterns therefore do not appear to account for increased productivity by women and gender researchers. She is currently studying the educational achievement of immigrant students. Linda Grant is an assistant professor of sociology and faculty associated of the Institute of Behavioral Research at the University of Georgia. Her current research focuses on gender and academic careers and gender relationships in schools. Her current research includes the feminist critique of sociology and publishing, and the U.S. women’s movement.  相似文献

The authors sought to assess the perception of risks for coronary heart disease (CHD) in college men and women. They surveyed 470 undergraduates from 2 major 4-year institutions who completed a questionnaire that measured perceived risks for heart disease. Sixty-eight percent of the respondents rated their risks as lower or much lower than those of their peers, indicating a clear optimistic bias. The research also revealed that the students who exercised regularly rated their risk of coronary disease lower than those who did not do so. In addition, women perceived a number of risk markers to be more potent or causative factors than men did. A significant number of participants did not comprehend commonly understood causal relationships associated with heart disease risk. The findings in this preliminary investigation suggest that college men and women do not accurately perceive their risks for developing heart disease.  相似文献

In the present paper we discuss the current status of drug treatment for pathological gambling and the scientific rationales underlying the various pharmacological approaches. Specifically, we summarize the treatment study results of serotonin reuptake inhibitors, mood stabilizers, opioid antagonists, and atypical antipsychotics in pathological gambling. We also discuss dosage strategies, the duration of treatment, issues surrounding medication compliance, and approaches to treatment-refractory pathological gambling, such as pharmacological and behavioral augmentation.  相似文献

Nurses with a medical-surgical clinical focus often care for patients with psychiatric and behavioral issues in acute care hospitals. This article describes how hospital staff and nursing and theater department faculty joined forces to develop realistic simulated psychiatric scenarios for use by practicing nurses.  相似文献

Using actors in simulation provides opportunities for immersive, interactive, and reflective experiences to improve health care professionals' clinical expertise and practice. These experiences facilitate the development of enhanced critical thinking, problem-solving, and communication skills without risks to patients. This article discusses how to integrate actors and students into simulated experiences. Examples are provided using mental health simulations with actors as standardized psychiatric patients.  相似文献
