This continuing education course for professionals involved in all areas of clinical trials integrates concepts related to the role of randomization in the scientific process. The course includes two interactive lecture and discussion sections and a workshop practicum. The first interactive lecture introduces basic clinical trial issues and statistical principles such as bias, blinding, randomization, control groups, and the importance of formulating clear and discriminating clinical and statistical hypotheses. It then focuses on the most commonly used clinical study designs and the corresponding patient randomization schemes. The second interactive lecture focuses on the implementation of randomization of patients and drug supply through allocation and component ID schedules. The workshop practicum, conducted in small groups, enables students to apply the lecture concepts to real clinical studies. Flexibility was built into the workshop practicum materials to allow the course content to be customized to specific audiences, and the interactive lecture sessions can be stretched to cover more advanced topics according to class interest and time availability. 相似文献

This paper examines the effect of the common practice of reserving slots for urgent patients in a primary health care practice on two service quality measures: the average number of urgent patients that are not handled during normal hours (either handled as overtime, referred to other physicians, or referred to the emergency room) and the average queue of non‐urgent or routine patients. We formulate a stochastic model of appointment scheduling in a primary care practice. We conduct numerical experiments to optimize the performance of this system accounting for revenue and these two service quality measures as a function of the number of reserved slots for urgent patients. We compare traditional methods with the advanced‐access system advocated by some physicians, in which urgent slots are not reserved, and evaluate the conditions under which alternative appointment scheduling mechanisms are optimal. Finally, we demonstrate the importance of patient arrival dynamics to their relative performance finding that encouraging routine patients to call for same‐day appointments is a key ingredient for the success of advanced‐access. 相似文献

This study assessed unmet service needs of rural older adults with Alzheimer's disease (AD) and identified factors that were related to these needs. Data were collected from 109 informal caregivers of AD patients. Over half of the patients experienced unmet service needs in 1 or more areas of activities of daily functioning. Informal caregiver burden and patient's gender and functional status were significantly related to patients' unmet service needs. Patients' use of formal services was marginally related to their unmet service needs. To better address patients' service needs, a comprehensive needs assessment should be conducted with both patients and their caregivers. 相似文献

The reception of Forrest Bess's work has primarily portrayed the artist as a “visionary” without external influence. By doing this, critics have downplayed the historical and cultural moment of Bess's productions and, subsequently, the well-developed interpretive models available from the history of art. This essay positions Bess and his work within the New York School of painting and its critical discourses of gendered metaphors and heteronormative formal evaluation. Recognizing how the artist participated in the conventions of vanguard painting of this time period offers new insights into Bess's singular style. Bess's works reveal the blind spots created by the visual grammar of Abstract Expressionism in his attempts to figure his repressed same-sex desires. 相似文献

This study describes associations of partner‐specific relationship characteristics with consistent condom use among 297 young people (ages 13–24) with sexually transmitted diseases (STD). Relationship‐specific variables were relationship quality, reasons for sex, relationship duration, duration of sexual relationship, coital frequency, “established” versus “new” sexual partner, cohabitation, children, sexual coercion, and drug or alcohol use associated with coitus. Relationship characteristics associated with consistent condom use included lower relationship quality, lower emotional reasons for sex, lower coital frequency, sex with a new partner, noncohabitation, and not having a child with the partner. Controlling for sociodemographic variables, factors exhibiting independent associations with consistent condom use were lower relationship quality, lower coital frequency, and not having a child with the partner. While condom use with potentially high risk new partners is important, other types of relationships are also risky but associated with lower likelihood of consistent condom use. Better understanding of complex relationship characteristics is necessary to improve STD intervention programs. 相似文献

Heterosexuals' attitudes toward lesbians and gay men: Correlates and gender differences 总被引:1,自引:0,他引:1
Gregory M. Herek Ph.D. 《Journal of sex research》2013,50(4):451-477
This paper discusses the basis for differences among heterosexuals in their reactions to gay people, with special emphasis on the issue of gender differences. Three studies conducted with students at six different universities revealed a consistent tendency for heterosexual males to express more hostile attitudes than heterosexual females, especially toward gay men. The same social psychological variables appear to underlie both males’ and females’ attitudes toward both gay men and lesbians: religiosity, adherence to traditional ideologies of family and gender, perception of friends’ agreement with one's own attitudes, and past interactions with lesbians and gay men. The role of these variables in shaping attitudes is discussed and areas for future research are proposed. Construction and validation of the Attitudes Toward Lesbians and Gay Men (ATLG) scale are also described. 相似文献

The present paper describes an eight‐week psycho‐educational group model that is easily adaptable to any agency that is concerned with a comprehensive package of services for counseling HIV + persons, as well as for others involved in the long‐term management of issues related to the health threat presented by HIV infection. 相似文献
