Information-driven coordination: experimental results with heterogeneous individuals

We study experimentally a coordination game with N heterogeneous individuals under different information treatments. We explore the effects of information on the emergence of Pareto-efficient outcomes, by means of a gradual decrease of the information content provided to the players in successive experiments. We observe that successful coordination is possible with private information alone, although not on a Pareto-optimal equilibrium. Reinforcement-based learning models reproduce the qualitative trends of the experimental results.     

Postdrinking sexual perceptions and behaviors toward another person: Alcohol expectancy set and gender differences

Based on research showing that alcohol expectancy and gender both play a role in sexual perceptions, we factorially crossed the apparent drinking status of yoked pairs consisting of a participant and a target person (a confederate posing as co‐participant). Alcohol expectancy interacted with gender in complex ways to influence sexual perceptions. We also found behavioral effects: men showed more erotic material to both male and female targets than women did. Men perceived the target as more sexually aroused by erotic material than women did. Men also showed more erotic material to drinking targets than to non‐drinking targets. Sexual perceptions and erotica‐showing behavior were correlated significantly and positively. We discuss these findings in terms of implications for postdrinking heterosexual encounters.     

Coping With Antigay Violence: In-Depth Interviews With Flemish LGB Adults

In view of the possible negative mental health outcomes of antigay violence and the limited understanding of how lesbian, gay, and bisexual (LGB) men and women cope with such experiences, this study examined the coping and social support-seeking strategies that victims adopt. In 2012, in-depth interviews were conducted with 19 Flemish sexual minority victims of violence. These in-depth interviews show that antigay violence can generate profound negative outcomes. However, the respondents employed a range of coping strategies, of which four were discerned: (1) avoidance strategies, (2) assertiveness and confrontation, (3) cognitive change, and (4) social support. Applying a diverse set of coping strategies and actively attaching meaning to negative experiences helps victims of antigay violence to overcome negative effects such as fear, embarrassment, or depressive feelings. However, the presence of a supportive network seems an important condition in order for these positive outcomes to occur.

Integrating risk assessment and life cycle assessment: a case study of insulation.

Increasing residential insulation can decrease energy consumption and provide public health benefits, given changes in emissions from fuel combustion, but also has cost implications and ancillary risks and benefits. Risk assessment or life cycle assessment can be used to calculate the net impacts and determine whether more stringent energy codes or other conservation policies would be warranted, but few analyses have combined the critical elements of both methodologies In this article, we present the first portion of a combined analysis, with the goal of estimating the net public health impacts of increasing residential insulation for new housing from current practice to the latest International Energy Conservation Code (IECC 2000). We model state-by-state residential energy savings and evaluate particulate matter less than 2.5 microm in diameter (PM2.5), NOx, and SO2 emission reductions. We use past dispersion modeling results to estimate reductions in exposure, and we apply concentration-response functions for premature mortality and selected morbidity outcomes using current epidemiological knowledge of effects of PM2.5 (primary and secondary). We find that an insulation policy shift would save 3 x 10(14) British thermal units or BTU (3 x 10(17) J) over a 10-year period, resulting in reduced emissions of 1,000 tons of PM2.5, 30,000 tons of NOx, and 40,000 tons of SO2. These emission reductions yield an estimated 60 fewer fatalities during this period, with the geographic distribution of health benefits differing from the distribution of energy savings because of differences in energy sources, population patterns, and meteorology. We discuss the methodology to be used to integrate life cycle calculations, which can ultimately yield estimates that can be compared with costs to determine the influence of external costs on benefit-cost calculations.     

“I Am Not a Prostitute”: How Young Black Women Challenge Street-based Micro-interactional Assaults

ABSTRACT

Few scholars have examined the collective experiences of young African American women living in the inner city and their strategies for navigating daily life there. I draw on nearly two years of field research in Central East Oakland, CA, to provide an ethnographic account of the daily experiences of poor young black women in urban public space¹. I uncover a particular and routine type of public encounter, street-based micro-interactional assaults, that follow a pattern and are shaped by an act or a threat of sexual violence. I also examine how poor black women feel about and negotiate these events while trying to maintain their own safety.     

Predictors of Family Support and Well-Being Among Black and Latina/o Sexual Minorities

ABSTRACT

Sexual minorities are receiving an increasing amount of attention within sociological research on families. However, much of the existing work on these families has been limited to largely White, middle-class, and highly educated individuals. Using national data from the Social Justice Sexuality Project, this study fills a much-needed gap by exploring predictors of family support and the relationship between family support and well-being among Black and Latina/o sexual minorities. We find that sexual identity, how out one is to one's family, and relationship status predict levels of family support. In addition, we find that among Black and Latina/o individuals, family support is an important factor influencing health and well-being. Other social statuses such as gender identity, sexual identity, and relationship status are associated with happiness and self-rated health as well. Our work suggests that sexual minorities of color have unique family dynamics that should be studied from an intersectional perspective. Further investigation into the family dynamics of sexual minorities of color should pay particular attention to individuals' positionality within systems of gender, racial, and sexual identity disadvantage to help understand their health and well-being.

How Believing in Ourselves Increases Risk Taking: Perceived Self-Efficacy and Opportunity Recognition

What effect does positive and negative feedback about past risk taking have on the future risk taking of decision makers? The results of an experimental study show that subjects who are led to believe they are very competent at decision making see more opportunities in a risky choice and take more risks. Those who are led to believe they are not very competent see more threats and take fewer risks. The feelings of self-competence and self-confidence on one task did not generalize to a similar task. Perception of opportunities was unexpectedly not related to the perception of threats. As executives bring their personal perceptual biases to firm decision making, our results identify a serious built-in bias in SWOT analysis (the analysis of firms' strengths and weaknesses as related to potential opportunities and threats). Executives who believe that they and their firm are very competent will take more risks and vice versa. Our results also provide evidence that the perceived likelihood of an event depends on whether the event is a loss or a gain. Human decision making is subject to the general bias that outcome expectations are not independent of outcome valuations.
