Moderating Effects of Aggression on the Associations Between Social Withdrawal Subtypes and Peer Difficulties During Early Adolescence

Recent research has revealed significant heterogeneity in the peer difficulties associated with social withdrawal subtypes during early adolescence, but little is known about possible sources of that heterogeneity. This study of 194 Indian young adolescents (48% female; 90% Hindu; M age= 13.35 years) evaluated whether the peer adversity related to self-reported social withdrawal subtypes (shyness, unsociability, avoidance) varied as a function of peer-nominated overt and relational aggression, and gender. Regression analyses revealed that overt aggression and gender moderated the pathways between shyness and peer exclusion and peer victimization such that the associations were significant and positive only for boys who were high and girls who were low in overt aggression. Several additional moderator effects were found, including results revealing that relational aggression (in certain cases, in conjunction with gender) moderated the association between: (1) avoidance and peer exclusion and peer rejection, (2) shyness and peer rejection, and (3) unsociability and peer victimization. For adolescents who were average and low in relational aggression, avoidance was positively related to peer rejection, and unsociability was positively related to peer victimization. However, only for boys who were high in relational aggression, avoidance was found to be positively related to peer exclusion, and shyness was positively related to peer rejection. The findings highlight the importance of considering additional individual risk factors in studies of social withdrawal subtypes and point to important differences for young adolescent withdrawn boys and girls.     

What judges know about eyewitness testimony: A comparison of Norwegian and US judges

Abstract

We surveyed 157 Norwegian judges about their knowledge and beliefs about eyewitness testimony, and compared their answers to a prior survey of 160 US judges. Although the Norwegian judges were somewhat more knowledgeable than the US judges, both groups had limited knowledge of eyewitness testimony. The Norwegian judges, like the US judges, frequently differed from eyewitness experts in their responses to such important issues as whether eyewitness confidence is related to identification accuracy at trial and what is the best method for conducting identification procedures. As was true for the US judges, more knowledgeable Norwegian judges had many of the beliefs that may be necessary for reducing and mitigating the effects of eyewitness error. The results suggest that increasing judges’ knowledge of eyewitness testimony may be an important component of the solution to eyewitness error.     

An investigation of model forensic bone in soil environments studied using infrared spectroscopy

Infrared spectroscopy has been used to examine changes to bone chemistry as a result of soil burial. Pig carcasses were buried as part of a controlled field study, and pig bone was used in soil environments established in the laboratory. The variables of species type, bone pretreatment, soil type and pH, moisture content, temperature, and burial time were investigated. The crystallinity index (CI) and the organic and carbonate contents of the bones were monitored. The data revealed decreasing trends in the organic and carbonate contents and an increase in the CI of the bone with burial time. An acidic soil environment and soil type are the factors that have the most influence on bone chemistry as a result of burial. The study demonstrates the potential of infrared spectroscopy as a straightforward method of monitoring the changes associated with aging of bones in a variety of soil environments.     

Political Participation and Civic Courage: The Negative Effect of Transparency on Making Small Campaign Contributions

This study assesses whether public disclosure of campaign contributions affects citizens’ willingness to give money to candidates. In the American states, campaign finance laws require disclosure of private information for contributors at relatively low thresholds ranging from $1 to $300. The Internet has made it relatively easy to publicize such information in a way that changes the social context for political participation. Drawing on social influence theory, the analysis suggests that citizens are sensitive to divulging private information, especially those who are surrounded by people with different political views. Using experimental data from the 2011 Cooperative Congressional Election Studies, it demonstrates how individuals refrain from making small campaign contributions or reduce their donations to avoid disclosing their identities. The conclusion discusses the implications of transparency laws for political participation, especially for small donors.
