Sexual Behaviors and Perceptions of HIV Risk in a Multiethnic U.S. Sample of Women Who Have Sex with Women

Abstract

This study investigated the sexual practices and perceptions of HIV risk in a national sample women who have sex with women (WSW). A multiethnic sample of 239 WSW aged 18–68?years attending GLBTQ pride events in three U.S. cities (Chicago, Atlanta, and Fort Lauderdale) completed an anonymous survey regarding their sexual behaviors, thoughts and perceptions of HIV risk. In the past 6?months, 18% of participants reported one or more male partners. Perception of HIV risk was associated with having more male partners (r?=?.244, p?r?=?.185, p?r?=?.191, p?r?=?.169, p?r?=?.208, p?相似文献   

The psychiatric technician: trespasser or welcomed ally?

1. The increasing shortage of nurses, higher patient acuity levels, and greater demands placed on nursing to meet standards of care have contributed to the use of psychiatric technicians to alleviate the burden on nursing and ensure the delivery of quality patient care. 2. Psychiatric technicians provide care for a select group of patients under the supervision of the primary nurse. The patients assigned to psychiatric technicians require minimal direct nursing intervention. 3. Psychiatric technicians reported increased self-confidence and self-esteem; the nurses were able to perform more professional nursing activities, increasing their job satisfaction and promoting staff retention; and the patients received high-quality care.     

Sexual Communication and Seroadaptation Practices in HIV-Negative Midlife and Older Men Who Have Sex With Men

Advances in treatments have increased the longevity of people with HIV. The high prevalence of HIV among men who have sex with men (MSM) creates a greater risk for exposure that increases with age. Seroadaptation, which includes serosorting (sexual behavior and condom use based on knowing the serostatus of self and partners) and strategic sexual positioning (choosing receptive versus insertive anal sex), is sometimes used as an HIV risk-reduction strategy. This study examined seroadaptation, sexual communication, and HIV-risk behaviors in 420 sexually active HIV-negative MSM aged 40–81 years in South Florida via anonymous pen-and-paper questionnaire. Recreational drug use and serosorting (i.e., not using condoms if the partner said he was HIV-negative) were associated with higher risk for unprotected receptive anal intercourse. Younger age, greater number of partners, and serosorting were associated with higher risk for unprotected insertive anal intercourse. Understanding these behaviors in this group might help guide HIV-prevention efforts. Future research may examine the role of HIV-prevention medication (PrEP) in influencing sexual behavior in midlife and older MSM.     

Culture,Race, and the Economic Assimilation of Immigrants

The economic assimilation of European-origin immigrants is fairly rapid but selectively culture contingent; the economic assimilation of racial minority immigrants is less rapid and less culture contingent. Regression analysis of survey data examines occupational status and earnings effects of eight ethnic attachments among men and women in seven ethnic and racial minorities in mainstream and enclave employment in Toronto (N = 1792), controlling for foreign and domestically acquired human capital. Assimilationist pressures that the survey showed to be widely perceived may apply more to Europeans than to racial minorities. Economic assimilation is affected when foreignness is most pronounced: very selectively for European immigrants and universally for racial minorities treated as foreign, presumably based on skin color, regardless of specific culture, identity, behaviors, or network affiliations.     

An algorithm for discrete chebychev curve fitting for the simple model using a dual linear programming approach

An algorithm, in t h e form of a Fortran subroutine TRIPLE,is given to compute statistics forthetriples test for symmetry, The 2 computational complexity of the algorithm is O(n² ) which is an 3 improvement over the straightforward method, which is O(n³).
