This paper develops a warning zone approach to make variance investigation decisions for a multiperiod process. The assumed cost generation process varies between an in-control and out-of-control state. These states cannot be directly observed, but must be inferred from the reported cost variances. Using the warning zone method of inference, the manager investigates the process whenever an upper threshold is exceeded or a lower threshold is exceeded for two consecutive periods. A four-state Markov chain models the resulting decision process. Steady state probabilities are derived for this chain and are used to obtain explicit formulas for the effectiveness and efficiency of the decision process. These formulas permit computation of the cost savings attainable by the warning zone method. Compared to other decision rules, the warning zone method is much simpler than the theoretically optimal Bayesian revision method, but uses more information than the Markovian control limit method. Numerical comparison of results shows that the warning zone method usually captures most of the available cost savings, even in cases where the Markovian control limit method does not perform well.  相似文献

Abstract

Objective: This study examined the prevalence of mental health disorders and their clinical correlates in a university sample of lesbian, gay, bisexual, and queer (LGBQ) students. Participants: College students at a large public university. Methods: An anonymous, voluntary survey was distributed via random e-mail generation to university students during April and May of 2011. LGBQ students were compared with their heterosexual counterparts on psychological and physical status as well as academic performance. Results: LGBQ students reported worse depressive symptoms, higher levels of perceived stress, considered themselves less attractive, and were more likely to be overweight. LGBQ students were significantly more likely to report histories of affective, substance use, and certain anxiety disorders as well as compulsive sexual behavior and compulsive buying. Conclusions: The higher rates of many psychiatric conditions among LGBQ students underscore the need for universities to provide LGBQ students a nonjudgmental environment to discuss sexual orientation and health issues.  相似文献

Old lesbians of African descent have experienced racism, heterosexism, homophobia, and ageism. This article explores the topics of aging, ageism, heterosexism, and minority stress among older African-American lesbians. The narratives and subsequent analysis offer significant contributions to the dialogue regarding Black aging lesbians in the aging and lesbian, gay, bisexual, and transgender (LGBT) communities generally and in the African-American and African-American lesbian communities specifically.  相似文献

Abstract

Objective: To assess the use of alcohol screening tools across US colleges. Participants: Directors of health services at 333 four-year colleges. Methods: An online survey was conducted regarding the use of alcohol screening tools. Schools reporting use of formal tools were further described in terms of 4 tools (AUDIT, CUGE, CAPS, and RAPS) that the authors judged to be the most favorable based on prior empirical comparative studies. Results: Forty-four percent of colleges reported use of at least 1 formal alcohol screening tool and nearly all of these used a tool appropriate for college students. However, less than half of the 44% of colleges that used a screening tool used 1 of the 4 most favorable tools. Conclusions: Continued efforts are needed to encourage colleges to use the most effective available screening tools to identify alcohol-related problems that require intervention among students.  相似文献

This project is based on the results of telephone surveys with 52 local, state, and national informed respondents including policymakers, county leaders, planners, and advocates in mental health and aging with a particular focus on the states of California and Florida. This article addresses challenges to access to mental health services for diverse older adults including barriers related to race and ethnicity, socioeconomic status, location, age, gender, immigrant status, language, sexual orientation, and diagnosis. The article also highlights broad themes that emerged including (1) the importance of outreach and transportation tailored to diverse elders, and (2) recruitment of diverse staff and training related to diversity. The article concludes with policy and practice recommendations to reduce these disparities in access to mental health services for diverse populations of older adults.  相似文献

Learning curves have important implications for managerial planning and control. This paper considers the effect of learning on managerial planning models for productmix problems that can be handled by a linear-programming formulation. An approach to incorporate learning effects in the planning model is proposed in this paper. The feasibility and superiority of the proposed approach over the traditional approach are discussed through the use of a linear-programming problem.  相似文献

The Family Mentoring Project, which provided approximately one year of mentoring for at-risk 10-year old Latino children and their parents, aimed to provide not only service but empirical evaluation of the program's impact. This University-community partnership offered individual mentoring, a group educational component for children and parents, and group social/recreational activities. A pre- and post-test analysis of 11 non-mentored and 20 mentored youth revealed positive gains on social skills for mentored children as reflected in self-ratings and mothers' ratings on the Social Skills Rating Scale (SSRS). Also based on the SSRS, mothers reported decreases in three problem behaviors for mentored children. In addition, by post-testing, the mentored children and their mothers compared very favorably with the SSRS standardized samples on both skills and problem behaviors. The findings suggest that bicultural competence may be fostered by programs that provide consistent and long-term mentoring, involve the children's families, include group educational components, and bring families and mentors together for social/recreational events.  相似文献
