The issue of violent video game influences on youth violence and aggression remains intensely debated in the scholarly literature and among the general public. Several recent meta-analyses, examining outcome measures most closely related to serious aggressive acts, found little evidence for a relationship between violent video games and aggression or violence. In a new meta-analysis, C. A. Anderson et al. (2010) questioned these findings. However, their analysis has several methodological issues that limit the interpretability of their results. In their analysis, C. A. Anderson et al. included many studies that do not relate well to serious aggression, an apparently biased sample of unpublished studies, and a "best practices" analysis that appears unreliable and does not consider the impact of unstandardized aggression measures on the inflation of effect size estimates. They also focused on bivariate correlations rather than better controlled estimates of effects. Despite a number of methodological flaws that all appear likely to inflate effect size estimates, the final estimate of r = .15 is still indicative of only weak effects. Contrasts between the claims of C. A. Anderson et al. (2010) and real-world data on youth violence are discussed.

Youth violence, including bullying and other serious violent behaviors, has received increased political and scientific attention over the past several decades. Although violent behavior among youth and in the schools has declined over the past decade, the victimization of children by other children in school settings remains a major issue of concern. In response, a number of prevention and intervention programs have been developed to reduce the incidence of bullying and violence in schools. This meta-analysis attempted to examine the effect of school-based anti-bullying programs. Results suggested a significant effect for anti-bullying programs ( r = .12). However, this result seemed to be slightly influenced by publication bias and did not meet the adopted threshold for “practical significance.” The effect for programs targeted specifically at at-risk youth was slightly better, but overall, anti-bullying programs produce little discernible effect on youth participants. Reasons that anti-bullying programs may produce little effective change are discussed.

Using data from Louisiana State Police records on concealed weapon permits, this article analyzes factors related to regional differences in rates of handgun permit holding. Although protection from victimization may be considered a common motive for carrying a concealed weapon, the authors found no relationship between crime rates and rates of handgpn permit holding. Instead, factors such as median household income and race-related factors were found to be more salient predictors of an area's rate of permit holding.
