Rural/Urban Residence,Migration, HIV/AIDS,and Safe Sex Practices among Men in Zimbabwe*

Abstract The AIDS epidemic was initially thought to be primarily an urban phenomenon. However, migration between rural and urban areas has resulted in the spread of the virus to all segments of the population. Prevention efforts continue to focus on the ABCs of AIDS, namely, abstinence among young adults, being faithful within a monogamous relationship, and/or using condoms at each sexual encounter. We examine the effects of residence, migration status, and selected social and demographic variables on the use of these three practices among men in Zimbabwe, a nation experiencing one of the highest HIV/AIDS prevalence rates in the world. Both residence and migration status were found to be significantly related to safe sex practices. Knowledge of a source with easy access to condoms was the strongest predictor of this behavior. Knowledge of prevention methods and experience with persons with AIDS also exerted significant effects, although not always in the manner hypothesized. Possible reasons for the findings and implications for policy are discussed.     

Employment growth in high-tech new ventures

We specify and estimate a model of the early employment growth of technology-driven new ventures. Our estimated model is derived from labor demand theory. A data set of 100 German firms is used to conduct this analysis. The study’s findings support the relevance of the theory as applied to these nascent firms. Employment growth is significantly enhanced in ventures exhibiting high profits, experienced founders, formal information processes, and outsourced product distribution. Our findings also confirm aspects of Penrose’s theory of firm growth suggesting that transactions costs associated with larger founder teams may inhibit employment growth.     

Role of informal sector recycling in waste management in developing countries

Many thousands of people in developing country cities depend on recycling materials from waste for their livelihoods. With the focus of the Millennium Development Goals on poverty reduction, and of waste strategies on improving recycling rates, one of the major challenges in solid waste management in developing countries is how best to work with this informal sector to improve their livelihoods, working conditions and efficiency in recycling.The general characteristics of informal recycling are reviewed, highlighting both positive and negative aspects. Despite the health and social problems associated with informal recycling, it provides significant economic benefits that need to be retained. Experience shows that it can be highly counterproductive to establish new formal waste recycling systems without taking into account informal systems that already exist. The preferred option is to integrate the informal sector into waste management planning, building on their practices and experience, while working to improve efficiency and the living and working conditions of those involved. Issues associated with integrating informal recycling into the formal waste management sector are discussed.     

Changing Gender: The Discursive Construction of Equal Opportunities

This article provides a discursive perspective on the dilemmas of sameness and difference feminisms and their consequences for change projects. It explores how equal opportunity officers dealing with gender issues and introducing equality legislation in practice construct the meaning of equal opportunities. The analysis of the interpretative repertoires and ideological dilemmas drawn upon in ten interviews shows the highly context‐specific use of four different repertoires constructing gender equality: the sameness, difference, bandwidth and deconstructive repertoire. Interpreting the shifts between repertoires from the perspective of the ideological dilemma, new avenues for change are explored. The article concludes that the simultaneous use of all possible theoretical perspectives might be a worthwhile objective.     

TOWARD A SOCIOLOGY OF CULT FILMS: Reading Rocky Horror

This article provides a sociological reading of cult films, in particular, The Rocky Horror Picture Show. Cult films are secular documents, celebrated as sacred texts by audiences and used as shared foci to collectively create rituals and belief systems. They differ from popular re-releases, fad films, films with cult qualities, and critical cult films in that they involve typical people in atypical situations, sympathetic deviance, challenges to traditional authority, reflections of societal strains, and paradoxical and interpretable resolutions. Examination of the Rocky Horror text and the cult activities that occur during its viewing, reveal it as a paradoxical indictment and validation of traditional societal arrangements.     

The role of family help in the housing decisions of young people

Recent debates about flows of help within the family have indicated considerable diversity according to the type of help (money, services), and ages and gender of those involved, and have shown that values are only a partial guide to the scale of such flows. This paper focuses on a particular occasion for help, young people's housing, and a particular region, South-East England, where one would expect family financial help to be high given the capacity to help of older generations (due to higher average incomes and wealth) and the affordability problems faced by young people. It is shown that contrary to hypothesis only 12% of a sample of young people had received financial help for housing purposes since they had left home, less than found in previous studies with different samples. The amounts involved were less than young people believed their parents could afford. The role of inheritance was also found to be minor. The results from the different studies are explained as due to changes in the housing market, changing values regarding financial help and differences among the samples. Intensive re-interviews with three households from very different backgrounds are used to show the different ways in which family help operates.

Defining the linear portion of a sigmoid‐shaped curve: bend points

Formulae are provided that define the ‘bend points’, the beginning and end of the essentially linear dose–response region, for the four‐parameter logistic model. The formulae are expressed in both response and dose units. The derivation of the formulae is shown in order to illustrate the general nature of the methodology. Examples are given that describe how the formulae may be used while planning and conducting bioassays. Copyright © 2003 John Wiley & Sons, Ltd.
