Sexual Risk,Behavior, and HIV Testing and Status Among Male and Transgender Women Sex Workers and Their Clients in Lima,Peru

Objectives: To determine the socio-demographics, sexual practices, and HIV prevalence of male sex workers (MSWs), transwomen sex workers (TSWs), and their male clients in Lima, Peru. Methods: Following ethnographic mapping of sex work venues, the authors revisited randomly selected venues to survey MSWs, TSWs and their clients. Results: MSWs and TSW clients are more educated than MSW clients and TSWs. Only 50% of TSW clients have received HIV testing. Self-reported HIV positivity is highest among MSW clients and TSWs. Conclusion: Notable differences exist between MSWs and TSWs and their clients that can affect the health of these groups and warrant intervention.     

Non-response to the recycling promotion technique of blockleader and commitment

The use of the recycling promotion technique which consists of commitment through a blockleader incentive has demonstrated that those individuals who are reluctant to increase their collaboration in response to the technique do not differ substantially from those who respond positively to the promotion, in terms of the processing information style. This similarity is clear, not only from the longitudinal perspective, which considers the evolution of these cognitive and evaluative variables from before the promotion application, but also from a transversal perspective, in other words, how the relationships between these variables are structured in both types of response model. However, the implications for management are based on the differences in the details of the two response patterns and a line of research based on the phenomenon of reluctance is justifiably proposed.     

Media competition and information disclosure

This paper analyzes an election game where self-interested politicians can exploit the lack of information that citizens have about candidates’ preferred policies in order to pursue their own agendas. In such a setup, we analyze the incentives of newspapers to acquire costly information and that of politicians to make informative speeches, as well as how competition among the media affects such incentives. We show that the higher the number of potential readers and/or the lower the cost of investigating, the more the candidates tend to reveal their motives. We also show that the readers’ purchasing habits play a crucial role in the model. More specifically, we show that if readers always buy a newspaper, media competition favors information disclosure; whereas if they are opportunistic and just buy a newspaper in case news are uncovered, competition is not so desirable.

A New Chilean Migration Act: an Approach to International Standards

The current Chilean Migration Act is the oldest in South America. It was created under the paradigm of national security, not human rights, and today does not adequately serve a participating democratic state, active within the international community. The Chilean government will soon be moving to discuss in congress a new migration act. We want to emphasize that the government should not forget the importance of incorporating international standards of migration policy into the national sphere. Chile is part of the United Nations system and, as a participating member, ratifies all core human rights treaties. Given that the United Nations Human Rights Bodies have made recommendations about migration policy, it is essential that this discussion be brought to the attention of our governing officials. This article reviews the UN recommendations as a concrete approach to the implementation of international standards in Chilean migrant policy.     

Psychological Distress and Related Factors in Female College Students

Abstract

Objective: This study assessed the psychological distress in Spanish college women and analyzed it in relation to sociodemographic and academic factors. Participants and Methods: The authors selected a stratified random sampling of 1,043 college women (average age of 22.2 years). Sociodemographic and academic information were collected, and psychological distress was assessed with the Symptom Checklist-90–Revised. Results: This sample of college women scored the highest on the depression dimension and the lowest on the phobic anxiety dimension. The sample scored higher than women of the general population on the dimensions of obsessive-compulsive, interpersonal sensitivity, paranoid ideation, psychoticism, and on the Global Severity Index. Scores in the sample significantly differed based on age, relationship status, financial independence, year of study, and area of study. Conclusion: The results indicated an elevated level of psychological distress among college women, and therefore college health services need to devote more attention to their mental health.     

Disparities in the Quality of Pediatric Dental Care: New Research and Needed Changes

In the United States, there are significant disparities in the oral health of children from families with high and low socioeconomic status and between majority and minority children. Extant research on these health differences has focused predominately on caregiver knowledge, beliefs, and practices as well as structural barriers such as Medicaid coverage, dentist availability, and transportation issues. Little attention has been paid to the quality of care families experience when taking their child to the dentist or the ways in which dental schools train their students to work with young children. This policy report describes some of the experiences of low-income and ethnically diverse young children and their parents in dental clinics and highlights some of the weaknesses of dental training. We contend that increasing the standards for dental training and practice are necessary for improving young children's oral health and reducing these disparities.     

A bidimensional class of optimality criteria involving φp and characteristic criteria

A new biparametric class of criteria for Optimal Experimental Design generalizing the families of φ_p and Characteristic Criteria is presented. Some properties of the Characteristic Criteria are provided: in particular, differentiability, monotonicity and convexity. A statistical interpretation is also offered. Optimal designs with respect to Characteristic Criteria are obtained for polynomial and compartmental models and an extension of the Michaelis-Menten model. A thorough discussion for the trigonometric model is given. The computed optimal designs are shown to be quite efficient for A-, D- and D_s -optimality. Thus, some of them appear as a natural compromise between different optimality criteria. A simulation in multiple linear regression confirms the quality of Characteristic designs for discovering significant differences between parameters.
