Keeping Up with the Souzas: Social Influence and Electoral Change in a Weak Party System,Brazil 2002–2006

Despite weak partisanship and considerable political change in the wake of the 2002 election, three‐quarters of Brazilian voters supported a presidential candidate in 2006 from the same party they had backed in 2002. This article assesses the factors causing both electoral stability and electoral change with a transition model, a model testing whether the effects of respondents' evaluative criteria depend on their initial vote choices. Social context—personal discussion networks, neighborhood influences, and the interactions of social networks and municipal context—is the major force promoting stability and change, while the impact of partisanship is limited to a small share of voters.     

Legal liability and research ethics boards: the case of neuroimaging and incidental findings

Neuroimaging research covers a wide range of intriguing issues from revealing brain structures to investigating what happens in our brain when we lie. The field appears to be thriving, but skepticism and alertness to the various ethical, scientific, policy and philosophical challenges associated with it also appear to be on the rise. One particularly complex issue concerns what to do with incidental findings that emerge during the course of neuroimaging research. Research ethics boards (REBs) play a central role in research oversight. In this paper, we will consider some of the potential issues associated with REB liability in negligence in the context of incidental findings in neuroimaging research.     

Vertebral artery dissection complicating occipital injection of heparin for treatment of thoracic outlet syndrome

A 38-year-old woman with a 2-year history of chronic neck pain radiating down her right arm underwent radiological and neurological evaluations, which revealed no anatomical cause for her pain. She sought alternative therapies including intramuscular heparin injections. Following a right occipital injection of heparin, cyanocobalamin, and lidocaine, she had a sudden cardiorespiratory arrest and was successfully resuscitated, but did not regain consciousness.Computed tomography of the head and neck and subsequent autopsy revealed a right vertebral artery dissection, but at autopsy, no significant subarachnoid hemorrhage was noted at the base of the brain. This is the first case report where heparin (a potent anticoagulant) used in an occipital injection was documented to cause a vertebral artery dissection. It is also the first reported case where radiographically and histologically documented vertebral artery dissection did not present with overwhelming subarachnoid hemorrhage at the base of the brain. The subtle gross anatomical findings in this case highlight the importance of evaluating the cervical spinal cord in any case of sudden cardiorespiratory arrest following even apparently minor neck injury.     

Implicit attitudes toward violence among male perpetrators of intimate partner violence: a preliminary investigation

Whereas cognitive variables are hypothesized to play an important role in intimate partner violence (IPV) etiology and intervention, cognitive assessment methods have largely targeted offenders' explicit, controlled cognitive processing using paper-and-pencil questionnaires prone to social desirability biases. Using an implicit measure of attitudes (the Implicit Association Test [IAT]), we assessed attitudes toward gender, violence, and the association between gender and violence among 50 men enrolled in an IPV treatment program and a comparison sample of 40 nonviolent (NV) men. Although no group differences were noted on explicit attitudinal measures, men in the IPV group showed more positive implicit attitudes regarding violence, and a more rapid association between women and violence. Among men in treatment for IPV, the attitudes toward violence IAT was significantly correlated with self/partner-reported IPV frequency. In accordance with social information processing models of aggression, these results suggest that aggressogenic attitudes are likely to operate automatically and with little conscious deliberation. As a result, clinicians and researchers must adapt assessment and intervention strategies to capture both implicit and explicit aspects of cognitive processing.     

Individual and Marital Consequences of Victimization: Moderating Effects of Relationship Efficacy and Spouse Support

Marital dissatisfaction and depression are common characteristics of abused women. In this investigation, we attempted to identify variables that might buffer women's marital satisfaction and stability, and their psychological adjustment against the effects of verbal and physical abuse. Verbal and physical victimization had significant negative direct effects on women's marital satisfaction: victimized women were characterized by less satisfaction and less stability regardless of their sense of relationship efficacy or their perceptions of spousal support. However, the effects of victimization on women's depression were moderated by relationship efficacy, perceived intimacy, and acceptance of emotional expression provided by the spouse: nonvictimized women who perceived more support and felt more efficacious, relative to those who felt less support and less efficacy, experienced fewer depressive symptoms, while victimized women who perceived more support and felt more efficacious in their relationships, relative to those characterized by less support and less efficacy, experienced more depressive symptoms. In the context of marital violence, increasing levels of relationship efficacy and perceptions of spouse support may be accompanied by an increase in the risk for depressive reactions.     

Jurors' use of probabilistic evidence

Mock jurors' use of probabilistic evidence was examined in a fractional factorial design manipulating 7 variables: strength of nonstatistical evidence; quantification of nonstatistical evidence; strength of statistical evidence; combination of 2 pieces of statistical evidence; instruction in use of Bayes' theorem; and presentation of fallacies (both prosecutor's and defense attorney's) concerning use of statistical evidence. One hundred eighty-nine subjects viewed 1 of 16 videotapes presenting a condensed mock trial. Subjects completed dependent measures after each of 4 witnesses and at the end of trial. The strength of both nonstatistical and probabilistic evidence affected verdicts; the other manipulations did not. Overall, subjects slightly underused the probabilistic evidence, as compared to their individualized Bayesian norms, and subjects did not succumb to fallacies. However, subjects greatly varied in over-or underutilization, even after Bayesian instruction. Future research should examine use of weak nonstatistical evidence, and should test different probabilistic instructions.     

Do Interest Groups Compete? An Application to Endangered Species

Becker (1983) hypothesized thatinterest groups compete strategically forinfluence with policy makers; thatimportant model has been assumed or ignoredrather than tested. This paper buildstheoretical and econometric frameworks thatcan test hypotheses about strategicbehavior when data on interest-groupactivity are limited and discrete. Itapplies those frameworks to data oninterest-group pressure regarding additionsto the U.S. endangered species list. Theresults do indicate that these interestgroups respond to costs and benefits, butdo not support the hypothesis that pressurefrom one interest group increases ordecreases with the pressure intensity of anopposing group.     

Mendel's Ark: Conservation Genetics and the Future of Extinction

Amid the current biodiversity crisis and the ongoing threat of mass extinctions caused by modern anthropogenic factors such as industrialization, poaching and habitat destruction, conservation genetics provides tools (such as somatic‐cell nuclear transfer) that could help to ensure the survival of species and ecosystems. Yet as conservation genetics shifts from the laboratory and scientific communities into mainstream awareness, numerous political questions arise. For example, which species should be priorities for research and restoration via expensive biotechnology interventions? Does the increasing availability of biotechnological tools alter our perception of the biodiversity crisis and the natural world? Why are some stakeholders so opposed to using advanced biotechnology in conservation? Finally, and perhaps most controversially, what are the realistic outer limits of such tools with respect to the idea of “conquering extinction”?     

The biasing impact of pretrial publicity on juror judgments

This study examines three previously unexplored aspects of the biasing impact of pretrial publicity. First, this study tests the differential effects of several different types of pretrial publicity on juror decision making. Second, this study explores the impact the presentation of trial evidence has on biases created by pretrial publicity. Finally, the study explores the psychological processes by which pretrial publicity effects may operate. Results indicate that pretrial publicity, particularly negative information about the defendant's character, can influence subjects' initial judgments about a defendant's guilt. This bias is weakened, but not eliminated by the presentation of trial evidence. Character pretrial publicity, and both weak and strong inadmissible statements appear to operate by changing subjects' initial judgments of the defendant's guilt. This initial judgment then affects the way subjects assess the evidence presented in the trial and the attributions they make about the defendant. Prior record pretrial publicity appears to have its effects by influencing subjects' inferences about the criminality of the defendant and this is related to posttrial judgments.
