Revisiting Licensed Handgun Carrying: Personal Protection or Interpersonal Liability?

No debate is more sensitive or polemical than the question of ??gun rights?? in the U.S., and licensing private citizens to carry concealed handguns is the most controversial ??right?? of all. The morally charged nature of this controversy is reflected in the disparate results reported by various researchers who analyze the effects of these laws, and also by the especially intense methodological scrutiny that follows published research. A National Science Academy review of existing gun policy research issues methodological recommendations which may help resolve scientifically the question of whether or how ??right to carry?? licensing effects rates of lethal firearm violence. Similar efforts have been published previously, but this study improves upon those earlier efforts by increasing the sample cross-section, by further refining the model specification, and by distinguishing conceptually ??shall issue?? RTC laws from ??may issue?? RTC laws. The results provisionally suggest that the former increases homicide rates whereas the latter decreases them.

Prediction of Police Officer Performance Among New Mexico State Police as Assessed by the Personality Assessment Inventory

Little research has been conducted regarding the use of the Personality Assessment Inventory (PAI) in law enforcement screening and selection. The limited body of research that does exist appears to support its utility in the selection process. The purpose of the present study was to investigate the validity and reliability of the Psychological Rating Risk Factor Statement (PRRFS) developed by Roberts, Thompson, and Johnson (2004) in predicting and discriminating problem from non-problem New Mexico State Police (NMSP) applicants. PAI profiles for each officer were obtained and transferred into the PAI Law Enforcement, Corrections, and Public Safety Selection software program, which generated probability estimates (PRRFS) to predict the likelihood that participants were not well-suited for a career in law enforcement. Subsequent logistic regression and receiver operating characteristic (ROC) statistical analyses revealed that the PRRFS was ineffective in predicting and discriminating between problem and non-problem officers. Potential explanations for this finding are discussed.     

Recovery Rates of Human Fetal Skeletal Remains Using Varying Mesh Sizes

Human fetal skeletal elements of different gestational ages were screened with multiple mesh sizes (6.4 mm [1/4 inch], 3.2 mm [1/8 inch], 2.0 mm, and 1.0 mm) to determine their recovery rates. All remains were previously macerated, and no significantly damaged elements were used. The 6.4 mm mesh allowed a large loss of elements (63.2% overall), including diagnostic elements, while no diagnostic elements were lost when the 1 mm mesh (0.2%) was used. When using the 3.2 mm mesh, 16.2% of the bones were lost, including some diagnostic elements (primarily tooth crowns), while 7.5% were lost using the 2.0 mm mesh. The authors recommend that the potential loss of information incurred when utilizing larger mesh sizes be taken into consideration when planning recovery methods where fetal remains may be encountered and that a minimum of 1.0 mm mesh be utilized in recovery contexts known to include fetal remains.

Peer Victimization and Social Anxiety in Adolescents: Prospective and Reciprocal Relationships

This study used a 2-month prospective research design to examine the bi-directional interplay between peer victimization and social anxiety among adolescents. Participants included 228 adolescents (58% female) in grades 10–12. Three types of peer victimization were examined: overt (physical aggression or verbal threats), relational (malicious manipulation of a relationship, such as by friendship withdrawal), and reputational (damaging another’s peer relationships, such as through rumor spreading). Adolescents’ self-reported feelings of social anxiety and peer victimization experiences were assessed at two time points, in November and January of the same school year. Peer victimization was strongly related to adolescents’ social anxiety, and relational victimization explained additional unique variance. Moreover, peer victimization was both a predictor and consequence of social anxiety over time, with the most robust results found for relational victimization. Limited support was obtained for gender as a moderating variable. Findings highlight the deleterious effects of peer victimization, especially relational victimization, and suggest avenues for future research and clinical intervention for adolescents experiencing such victimization.

Does This Make Me Look Fat? Peer Crowd and Peer Contributions to Adolescent Girls’ Weight Control Behaviors

Based on the Theory of Reasoned Action, this study evaluated a “socialization” model linking girls’ peer crowd affiliations (e.g., Jocks, Populars) with their own weight concern, perceived peer weight norms, and weight control behaviors. An alternative “selection” model was also evaluated. Girls (N = 236; M age = 15.95 years) from diverse ethnic backgrounds completed surveys assessing peer crowd affiliation, their own concern with weight, perceptions of peers’ concern with weight, and weight control behaviors. Models were evaluated using SEM. The socialization model demonstrated good fit; the alternative selection model did not. Specifically, girls’ level of identification with certain peer crowds (Jocks, Burnouts, Alternatives) was associated with girls’ reported own concern and perceived peer concern with weight. Additionally, girls’ own concern and peer norms were related independently to girls’ weight control behaviors. Findings suggest that peer crowds and girls’ own and peer weight norms may be important targets of prevention efforts.
