Measuring socioeconomic status in health research in developing countries: Should we be focusing on households,communities or both?

Research on the effects of socioeconomic well-being on health is important for policy makers in developing countries, where limited resources make it crucial to use existing health care resources to the best advantage. This paper develops and tests a set of measures of socioeconomic status indicators for predicting health status in developing countries. We construct socioeconomic indexes that capture both household and community attributes so as to allow us to separate the social from the purely economic dimensions of the socioeconomic status within a cross-national perspective, with applications to data from Demographic and Health Surveys (DHS) fielded in five African countries in the 1990s. This study demonstrates the distinctive contributions of socioeconomic indexes measured at the household vs. community level in understanding inequalities in health and survival and underlines the importance of going beyond the purely economic view of socioeconomic status to cover the multidimensional as well as multilevel concept of economic and social inequality.     

Information and capacities

Most economists consider that the cases of negative information value that non-Bayesian decision makers seem to exhibit, clearly show that these models are not models representing rational behaviour. We consider this issue for Choquet Expected Utility maximizers in a simple framework, that is the problem of choosing on which event to bet. First, we find a necessary condition to prevent negative information vlaue that we call Separative Monotonicity. This is a weaker condition than Savage Sure thing Principle and it appears that necessity and possibility measures satisfy it and that we cand find conditioning rules such that the information value is always positive. In a second part, we question the way information value is usually measured and suggest that negative information values are merely resulting from an inadequate formula. Yet, we suggest to impose what appears as a weaker requirement, that is, the betting strategy should not be Statistically Dominated. We show for classical updating rules applied to belief functions that this requirement is violated. We consider a class of conditioning rules and exhibit a necessary and sufficient condition in order to satisfy the Statistical Dominance criterion in the case of belief functions.

Towards a modern gender gap in Europe?: A comparative analysis of voting behavior in 12 countries

This article examines electoral gender differences in Western Europe. It describes the electoral gender gap in a longitudinal cross-national design (1974–2000, 12 countries) with EuroBarometer data. The analysis shows that gender differences in voting in Europe follow a similar movement to what has been described for the USA. Women tended to vote more for conservative parties in the 1970s, while in the new millennium they have given higher support to left parties. The speed of this development differs cross-nationally and not all countries reached the state of a modern gender gap (where women lean left).At the national level the driving force for the emergence of a modern gender gap is mainly increased levels of female labor participation. At the individual level structural variables explain traditional gender differences in voting, but fail to account for the gender gap in recent years.     

Decisions with conflicting and imprecise information

When facing situations involving uncertainty, experts might provide imprecise and conflicting opinions. Recent experiments have shown that decision makers display aversion towards both disagreement among experts and imprecision of information. We provide an axiomatic foundation for a decision criterion that allows one to distinguish on a behavioral basis the decision maker’s attitude towards imprecision and disagreement. This criterion accommodates patterns of preferences observed in experiments that are precluded by two-steps procedures, where information is first aggregated, and then used by the decision maker. This might be seen as an argument for having experts transmitting a more detailed information to the decision maker.     

Validity evidence of the Portuguese adaptation of the Ambivalent Sexism Inventory / Evidencias de validez de la adaptación portuguesa de la Escala de Sexismo Ambivalente

Abstract

Modern forms of sexism have promoted the development of new scales and evaluation tools. The Ambivalent Sexism Inventory (ASI) (Glick & Fiske, 1996) aims to assess sexism along two dimensions: hostile sexism and benevolent sexism. The aim of this study is to present evidence of the validity of the factor structure of the Portuguese version of the ASI by analysing its structure and its relationships with neosexism and social dominance. The sample consisted of 446 Portuguese participants (68.6% female) between 17 and 77 years old. Results confirmed the two-factor structure; however, the best fit was registered with a four-factor structure: one hostile factor and three benevolent factors. Both hostile and benevolent sexism were correlated with neosexism and social dominance orientation. Future research should explore the dimensionality of the scale based on a four-dimension structure and its relationship to others sexism issues.     

The need to know caregiver perspectives toward using smart home technology

This article reviews the literature on adults with serious mental illness, their caregivers, and smart home technology. The article provides compelling evidence for social workers to undertake research aimed at investigating caregivers' perceptions toward using smart home technology for care of adult family members or friends with a serious mental illness. Empirical support for using smart home technologies with adults with serious mental illness is provided, and recommendations for future social work research are offered.     

Defining the Creole City by Walking: The Case of La Réunion

ABSTRACT

This paper presents exploratory work to understand the characterisation of the ‘Creole city’ inLa Réunion, through an analysis of three renovated districts. The purpose is to inform urbanrenewal programmes so that they take better account of local lifestyles and needs. Theresearch on representations and symbols involves a method to collect and analyse data thatcombines in situ situations and a strong day-to-day approach, namely, walking. This method,that may be used elsewhere, reveals the functioning qualities of traditional Creole cities as anurbanity that is adapted to its environment, and based on proximity and soft transport modes.     

An Evaluation of the Counseling on Access to Lethal Means (CALM) Training with an Area Agency on Aging

Firearms are a significant risk factor in suicide and older adults are disproportionately impacted in suicide by this means. This study investigated the impact of Counseling on Access to Lethal Means (CALM) training with geriatric case managers at an Area Agency on Aging. A concurrent mixed methods approach was used to explore 1) geriatric case managers’ attitudes, beliefs, and behavioral intentions about counseling on access to lethal means following CALM training, and 2) perceived barriers to assessing for suicidality and counseling clients on access to firearms. The CALM evaluation data was collected immediately posttest at CALM training, at three-month follow up. Results indicated that 38% of respondents reported they had, since CALM training, discussed reducing access to lethal means with clients and/or families. At three-month follow up, data showed that most beliefs, attitudes, and behavioral intentions about counseling clients and families on this topic increased. Focus group findings indicated that training had a positive effect on participants’ attitudes, beliefs, and behavioral intentions about counseling on access to lethal means.The findings of the present study offer additional evidence and implication for trainings of this type.
