The effects of seasonal demand on depot location

Many of the cost functions associated with depot location algorithms assume an overall demand for a fixed period, usually one year. This paper describes an investigation into the effect of high seasonality within such demand figures on the optimal location of storage facilities. The preliminary results indicate that a more flexible approach for certain products could be worthwhile.     

A Conceptual Model of the Alcohol Environment of College Students

Lobola is in many Southern African countries a tradition, which is expected to be adhered by anyone who is part of the community. It is paying respect to the elders, and the community. In order to determine how much the actual fact of payment of lobola would influence the behavior of husbands and wives, we conducted several focus groups. Many participants see lobola as part of their African culture, although they wished that they would not actually have to pay lobola. There is no difference in the husband's behavior, whether they had paid lobola or not and having extramarital affairs.     

Predictors of Safer Sex on the College Campus: A Social Cognitive Theory Analysis

Abstract

In April and May 1989, the authors surveyed a sample of students enrolled on four college campuses in New Jersey (N ? 923) concerning their HIV transmission-related behavior, knowledge, and a variety of conceptual variables taken primarily from social cognitive theory that were thought to be potentially predictive of safer sexual behavior. Analyses of sexually active, unmarried students' responses indicated that men expected more negative outcomes of condom use and were more likely to have sexual intercourse while under the influence of alcohol or other drugs, whereas women reported higher perceived self-efficacy to practice safer sex. Regression analyses indicated that, among the factors assessed, stronger perceptions of self-efficacy to engage in safer behavior, expecting fewer negative outcomes of condom use, and less frequency of sex in conjuction with alcohol or other drug use significantly predicted safer sexual behavior. Enhanced self-efficacy to discuss personal history with a new partner was associated with a greater number of risky encounters. Implications of these findings for intervention efforts with students are discussed.     

Sexual Attitudes and Behavior of University Students at a Rural South African University: Results of a Pilot Survey

A cross sectional qualitative and quantitative pilot survey, using self-administered questionnaire and focus group discussions, was conducted to assess the feasibility of a health promotion programme implemented at the university. About 73 students participated in the survey and the discussion. We examined gender and cultural differences on sexual attitude and behaviour. There was a strong belief that unprotected sex can lead to pregnancy and STIs. Overall participants were not sure if condom use had any negative effects, although female respondents felt that condoms affect the pleasure of sexual intercourse.

The results suggest that there is a need for health promotion programmes aimed at young adults, who attend university. The programme should improve general health knowledge, targeting health promotion and sexual risk behaviour among university students. Such a programme would have to consider gender, socio-economic circumstances as well as national and cultural background of the target population.     

Cattle for Wives and Extramarital Trysts for Husbands? Lobola, Men, and HIV/STD Risk Behavior in Southern Africa

Lobola is in many Southern African countries a tradition, which is expected to be adhered by anyone who is part or want to be part of the community. It is about paying respect to the elders, the family and the community. It is a significant element of marriage among many tribes and there are strict rules to adhere. In order to determine how much the actual fact of payment of lobola would influence the behavior of husbands and wives, we conducted several focus group discussion with men, women, mixed groups and couples. We analyzed the data collected during these sessions and compared these with the literature. Many participants see lobola as part of their African culture, although they wished that they would not actually have to pay lobola. We could not determine a difference in the husband's behavior, whether they had paid lobola or not and having extramarital affairs.

HIV among people with mental illness: contributing factors, prevention needs, barriers, and strategies

1. Findings suggest that PWMI, including those with serious mental illness, are sexually active although some individuals, including mental health professionals, perceive them to be asexual or not sexually active. 2. PWMI may be particularly susceptible to HIV risk-related behaviors due to poor judgment, limited impulse control, deficits in problem-solving skills, and suicidal intent and self-destructive behavior. 3. Nurses, due to their close interaction with PWMI, are in key positions to document HIV risk-related behaviors and to advocate for integrating HIV risk reduction strategies into the therapeutic milieu.     

The Effects of Three Types of Sexual Orientation Victimization on HIV Sexual Risk Behavior Among Black South African Men Who Have Sex With Men (MSM)

ABSTRACT

The goal of this study is to examine the relations between histories of three types of sexual orientation victimization (childhood, personal, and institutional) and HIV sexual risk behavior among Black South African men who have sex with men (MSM). Secondarily, this study examines whether marijuana use and problem drinking mediate the relations. Participants were 125 Black MSM recruited from neighborhoods in Eastern Cape Province, South Africa. Questionnaires administered through audio computerized self-interviewing assessed sexual orientation victimizations, problem drinking and marijuana use, and unprotected anal sex with casual partners. Data were analyzed using multiple regression and multiple mediation modeling.

Personal and institutional sexual victimizations were associated with condomless anal sex. Childhood sexual orientation victimization was positively associated with problem drinking. Neither problem drinking nor marijuana use mediated the relations between sexual orientation victimizations and having condomless anal sex with casual partners.
