Evaluation of two school‐based HIV prevention interventions in the border city of Tijuana,Mexico

This research project examined the individual and combined effectiveness of an HIV prevention workshop and a free condom distribution program in four high schools in Tijuana, Mexico. Adolescents (N = 320) completed baseline measures on sexual practices and theoretical correlates and participated in a two‐part study. In Study I, students were randomly assigned to an HIV prevention workshop or a control condition, with a 3‐month follow‐up assessment. Results indicate three significant workshop benefits regarding HIV transmission by altering sexual initiation, access to condoms, and traditional beliefs regarding condoms. In Study 2, we set up a condom distribution program at two of the participating schools, and students completed a 6‐month follow‐up assessment. Results indicate that exposure to the workshop followed by access to the condom distribution program yielded two beneficial results for reducing HIV transmission: moderating sexual initiation and increasing condom acquisition. Access to the condom distribution program alone had no effects on behavioral and psy‐chosocial correlates of HFV transmission. We discuss implications of these results.

Social networks and immigration stress among first‐generation Mandarin‐speaking Chinese immigrants in Los Angeles

This study examined relationships between social networks and immigration stress among first‐generation Chinese immigrants. Using data from a larger study of health behavior among first‐generation Mandarin/English‐speaking immigrants residing in the Los Angeles metropolitan area (N = 1,183), this study found that Chinese immigrants living closer to immediate family and maintaining larger social networks experienced lower immigration stress. Unexpectedly, immigrants with larger family sizes and who participated in voluntary associations (e.g., religious, alumni, and nationality associations) reported increased immigration stress. The findings suggest that practitioners need to be cautious of a possible downside in designing interventions to expand social networks among immigrant clients. The study is especially important in the context of a rapidly increasing immigrant population from Mainland China to the USA. Key Practitioner Message: ● Working with immigration families should incorporate assessment of their social network; ● Interventions designed to facilitate supportive social networks should differentiate different social network ties; ● Different social network ties may affect the stress level of immigrants differently.     

Corporate planning a review of questions and answers

This paper is about corporate planning, seen primarily but not exclusively from the viewpoint of operational research. The reasons for the rise of interest in corporate planning are examined, as are the contributions which O.R. has made or can make to corporate planning problems. An abstract discussion of these problems concentrates on those posed by increasing “connectedness” in the environment. After comparing the responses of the “commonsense manager”, the model-oriented operational researcher, and the cybernetician, the question is posed: “How can the operational researcher or planner enhance the adaptive capability of his organization?” A case study illustrates one possible form of solution, the “modular” approach; and another, the “zoom-lens” is outlined. The relevance of global system modelling to the widening problems of the corporate planner is also considered, and related to the concepts previously discussed.
