Divergent genetic strata in five Bahamian islands

Based on historical records, the genetic landscape of the Bahamian archipelago is presumed to be complex and to exhibit island-specific characteristics, yet the genetic composition of the island chain, which could corroborate or refute these past accounts, remains poorly defined. As such, the current investigation was undertaken to genetically characterize 5 Bahamian populations representing the Northwest (Grand Bahama and Abaco) and Central (Eleuthera, Exuma and Long Island) Bahamas across the 15 autosomal Identifiler loci routinely employed in forensic analyses. Altogether, our findings suggest that Bahamians are a genetically heterogeneous group, with each island sampled receiving differential contributions from African, European, East Asian and Native American sources. Even though the strongest genetic signal in all 5 collections emanates from continental Africa, inter-island differentiation is noted in both the Structure and admixture analyses. The presence of alleles not in common among the 5 insular populations also signals genetic heterogeneity among the islands of the archipelago. This is especially the case when considering the Long Island population, which exhibits statistically significant genetic differences in relation to the other Bahamian collections and the New World groups of African descent (Afro-American and Afro-Caribbean) in the G-test pair-wise comparisons, even after application of the Bonferroni adjustment.     

The Beauty Premium: Physical Attractiveness and Gender in Dictator Games

Are beautiful people better negotiators? In this article, I present evidence from a simple bargaining game in which players listened to prerecorded speeches and viewed the pictures of other players. I found that physically attractive players received a greater share of the surplus when their partners could both listen to their speeches and view their pictures. This effect was strongest when the listening partner was female. These results suggest new directions for experimental and empirical research on the role of nonresumé characteristics on labor market outcomes, and also has implications for those practitioners involved in negotiations characterized by extreme power imbalances between the parties.

Framing Contests and Policy Conflicts over Gas Pipelines

This paper compares and contrasts high‐conflict policy debates over the siting of three natural gas pipeline projects at different decision stages of the siting process. This paper draws on over 600 newspaper articles spanning 3 years, analyzed through Discourse Network Analysis. Drawing from the Advocacy Coalition Framework and Policy Conflict framework, this paper finds that actor framing of opposing policy beliefs involves more indirect than direct confrontations, with statements in the media waxing and waning over time. Opponents of the pipelines more often explicitly argue against pipelines, while also using a broad range of conceptual arguments, whereas proponents more often couch their arguments around the economic benefits of pipelines and use fewer conceptual frames overall. We also find evidence that opposing coalitions use similar framing across different decision contexts. This paper concludes with a commentary on the status and contributions of this paper to the study of policy conflicts and next steps in advancing similar research agendas.     

The personal vote and economic reform

Do electoral rules affect the progress of economic reforms? The students of economic reform have examined the effects of inter-party competition, partly shaped by electoral rules, on economic reform, but have neglected the more direct effects of electoral rules, namely the extent to which they encourage the personal vote. More broadly, studies of the effect of electoral rules on economic policy have relied on the simplistic SMD/PR distinction and have neglected features of electoral institutions that affect the level of intra-party competition. Building on the personal vote literature, we argue that electoral institutions that encourage the personal vote are not conducive to reform progress. We provide the first systematic multivariate cross-country test of the implications of the personal vote literature for economic reform in the context of the post-communist countries from 1990 to 2006. We find that, in line with our theory, countries where electoral rules encourage the personal vote are less likely to reform.     

Addressing the Issues: The Choice of Environmental Conflict‐Resolution Venues in the United States

Environmental conflicts are the catalyst for policy and institutional changes, and they are expected to increase due to rising populations, economic growth, and climate change impacts. Yet, environmental conflicts and the venues used to address them have not been thoroughly examined. A common‐pool resource dilemmas typology is used to categorize environmental conflict issues and to develop hypotheses relating conflict issues to resolution venues. The hypotheses are tested on western water‐resource conflicts. The capacity of venues to address the underlying conflict issues as well as how some venues tend to work in tandem are important for explaining the matching of conflict type to venue.     

Left High and Dry? Climate Change,Common‐Pool Resource Theory,and the Adaptability of Western Water Compacts

Efforts to reduce greenhouse gas emissions are falling far short of what a consensus of scientists argues is necessary to avoid potentially catastrophic increases in the mean global temperature. Increasingly, attention is devoted to understanding the vulnerability and adaptability of social and ecological systems to climate change in particular areas of the world. In the Western United States and other semi‐arid regions of the world, possibly the most immediate, direct impacts of climate change involve the availability of water resources. Scientific evidence suggests that the West is likely to become hotter and drier and will experience greater variability in precipitation. These changes will affect tens of millions of residents in Western states, and nearly every sector of the economy, especially agriculture. The logic of common‐pool resource theory is applied in this Theory to Practice essay to assess the vulnerability and adaptability to climate change of interstate river compacts and to offer recommendations for coping with climate change. Future areas of research on this critical topic are also outlined.

In Vivo Facial Tissue Depth for Canadian Aboriginal Children: A Case Study from Nova Scotia,Canada

This study examines facial tissue depth in Canadian Aboriginal children. Using ultrasound, measurements were taken at 19 points on the faces of 392 individuals aged 3–18 years old. The relationships between tissue thickness, age, and sex were investigated. A positive linear trend may exist between tissue thickness and age for Aboriginal females and males at multiple points. No points show significant differences in facial tissue depth between males and females aged 3–8 years old; seven points show significant differences in facial tissue depth between males and females aged 9–13 years old; and five points show significant differences in facial tissue depth between males and females aged 14–18 years old. Comparisons were made with White Americans and African Nova Scotians. These data can assist in 3‐D facial reconstructions and aid in establishing an individual's identity. Previously, no data existed for facial tissue thickness in Canadian Aboriginal populations.     

Note takers who review are less vulnerable to the influence of stereotypes than note takers who do not review

Abstract

The current research investigated whether the opportunity to review reduced note takers' vulnerability to the influence of stereotypes when making decisions. Participants were presented with a trial in which a man or a woman had been charged with a stereotypically masculine crime. Results revealed that note takers who did not review were more likely to find a man guilty than a woman, and attributed a higher degree of offender relevant traits to a man than to a woman. Non-note takers and note takers who reviewed did not engage in stereotype-based processing. It was concluded that the provision of dedicated review periods reduced the extent to which note takers were influenced by stereotypes during decision making. Future research may consider investigating whether the benefit of dedicated review periods remains when jurors are presented with longer trials and when they are required to engage in deliberation.     

Evidence for Social and Behavior Problems in Low-Income,Urban Preschoolers: Effects of Site,Classroom, and Teacher

Teacher ratings of 336 preschool children (mean age = 48 months) attending two urban Head Start programs were collected to examine the influence of contextual variables of teacher training, classroom, and site on the prevalence of significant problems. The prevalence of externalizing behaviors in the problem range was higher than expected and fewer children were rated in the well-adjusted range on social competence measures. Psychometric characteristics of the ratings indicated that teachers in this urban setting were less consistent in their ratings of internalizing problems, calling into question the lack of elevation of such problems in this population. Ratings by teachers and teacher assistants of the same children showed low agreement; the level of ratings was not affected by differences in training but did vary across classrooms. Hierarchical linear modeling analyses of the entire sample showed significant effects of classroom and site on problem behaviors and social competence. These results reveal the wide variation in problem frequency across classrooms, which needs to be considered in the implementation and evaluation of evidence-based interventions. Further, these results point to the importance of studying possible lasting effects on children exposed to these differing contexts.
