Cognitive tempo,violent video games,and aggressive behavior in young boys

In a factorial design, impulsive and reflective children played video games with aggressive or nonaggressive themes. Interpersonal aggression and aggression toward inanimate objects were assessed in a free-play setting and interpersonal aggression was assessed during a frustrating situation. Results indicated that subjects who played the video game with aggressive content exhibited significantly more object aggression during free-play and more interpersonal aggression during the frustrating situation than youngsters who played nonaggressive video games. Aggressive behavior was unaffected by cognitive tempo.     

Child support enforcement policy and unmarried fathers' employment in the underground and regular economies

Some scholars have suggested that a negative consequence of strengthening child support enforcement is to encourage fathers to shift from regular sector to underground employment. We employ data from the Fragile Families and Child Wellbeing Study to investigate the relationship between the strength of child support enforcement (CSE) and levels of underground and regular sector employment among unmarried fathers. We find that, in general, living in a city with stricter CSE is associated with fewer hours of underground employment. We find little evidence that stronger enforcement is associated with employment or hours in the regular sector. © 2007 by the Association for Public Policy Analysis and Management.     

A re‐examination of welfare states and inequality in rich nations: How in‐kind transfers and indirect taxes change the story

Previous studies find large crossnational differences in inequality amongst rich Western nations, due in large part to differences in the generosity of welfare state transfers. The United States is the least generous nation and the one having the most aftertax and transfer inequality. But these analyses are limited to the effects of cash and nearcash transfers and direct taxes on incomes, while on average, half of welfare state transfers in rich nations are inkind benefits—health insurance, education, and other services. Counting inkind benefits at government cost and accounting for the indirect taxes used to finance transfers substantially reduces crossnational differences in inequality at the bottom of the income distribution. The findings have implications for how we think about tradeoffs across welfare state domains that all nations face and we illustrate this with reference to the current U.S. debate about health insurance. © 2006 by the Association for Public Policy Analysis and Management     

Improving information evaluation for intelligence production

National security decision-making is informed by intelligence assessments, which in turn depend on sound information evaluation. We critically examine information evaluation methods, arguing that they mask rather than effectively guide subjectivity in intelligence assessment. Drawing on the guidance metaphor, we propose that rigid ‘all-purpose’ information evaluation methods be replaced by flexible ‘context-sensitive’ guidelines aimed at improving the soundness, precision, accuracy and clarity of irreducibly subjective judgments. Specific guidelines, supported by empirical evidence, include use of numeric probability estimates to quantify the judged likelihood of information accuracy, promoting collector-analyst collaboration and periodic revaluation of information as new information is acquired.     

DNA identification of "Earthquake McGoon" 50 years postmortem

This report describes the genetic identification of James "Earthquake McGoon" McGovern, a WWII fighter ace who perished in Laos while providing supplies to French troops during the French Indochina war. Because reference samples were unavailable for all of the potential casualties, testing of the entire mitochondrial genome, autosomal STRs and Y-chromosomal STRs was performed to increase the genetic information available for analysis. Kinship analyses performed on the evidentiary data and numerous indirect family references for McGovern excluded other possible casualties and definitively established McGovern's identity. This particular case demonstrates the practical utility of novel research technologies and aggressive genetic typing protocols in the identification of aged, degraded remains.     

External influence on parliamentarians in Kenya

Many scholars argue that the media can influence parliamentarians though the extent of that influence is hotly debated. There is some evidence that the relationship is two way, with politicians taking note of salient media stories but using the media to communicate with their constituents. It is also apparent that, whilst the media may have a role in drawing attention to specific issues, politicians in Kenya do not entirely trust it and thus use a wide range of other sources including government agencies as well as third party sources such as interest groups. This article addresses two gaps in our knowledge―the extent to which parliamentarians in Kenya turn to unofficial sources for information and public opinion, especially interest groups, and the extent to which the media in particular influences parliamentarians in Kenya. The results suggest that parliamentarians in Kenya rely to some extent on both the media and interest groups and that the media is good at raising awareness and stimulating action but that it has only a modest effect on political actions.
