Comparative Evaluation of Potentially Radiolucent Projectile Components by Radiographs and Computed Tomography

Projectile components that are traditionally radiolucent can be of considerable importance in determination of weapon type and caliber, but they are often missed on evaluation of postmortem radiographs. We hypothesized that these components would be significantly better visualized by evaluation of computed tomography (CT) scans compared to the practice standard of radiography alone. In this project, potentially radiolucent projectile components were both pulled apart and fired, and the radiolucent components were recovered. These components were embedded in blocks of ballistics gelatin and were imaged using both radiography and CT. The scans were evaluated by three blinded, board‐certified radiologists for the presence/absence of projectile components and true‐negative regions in each block. If a radiologist indicated visualization of a projectile component, they were further requested to describe their observation. It was found that traditionally radiolucent projectile components are not significantly more often identified on CT scans than radiography (p < 0.05).     

The Effect of Time and Temperature on the Persistence and Quality of Latent Fingerprints Recovered from 60-Watt Incandescent Light Bulbs

To understand how time and temperature could affect latent fingerprints, wooden pallets were used to construct five units that each housed ten 60-watt incandescent light bulbs. Fingerprints were deposited on the top, middle, and base of the globes. The bulbs were powered on (except the control bulb in each unit) for 18, 48, 72, 120, 168, 336, 504, and 672 h. Fingerprints recovered from the bulbs by tape lift after black powder processing were given a quality score. A thermal imaging camera determined temperatures on three areas of the bulbs. Fingerprints on the top of the globe (156.3°C) had the lowest quality score, and fingerprints on the middle of the globe (112.6°C) had the highest quality score. The mean quality scores of the three temperature classes were within one standard deviation of one another, meaning there is no way to estimate fingerprint age based on its quality after heat exposure.     

Eating Regulation Styles, Appearance Schemas, and Body Satisfaction Predict Changes in Body Fat for Emerging Adults

Obesity and high body fat percentages are a major public health issue. The percentage of obese and overweight Americans has increased over the past 30 years. On average, overweight individuals with higher percent body fat than normal weight individuals are at increased risk for numerous negative outcomes both physically and mentally. A prime time to investigate changes in body composition and associated psychological influences on decision making is during the emerging adulthood period. The first few years of college are a time when adolescents begin to regulate for themselves their own eating behaviors. Previous research shows that freshmen gain weight and increase in percent body fat during their first year of college. The current study addresses the limitations of previous research by investigating (1) individual growth in percent body fat over a longer period of time in college than previous available research and (2) important psychological and sex differences in this growth. This study measures percent body fat across the first 3 years of college at 8 time points for 542 undergraduates (351 females, 65 %; 191 males, 35 %). Longitudinal data analysis was conducted to identify changes in percent body fat, psychological predictors of those changes, and how changes differ for males and females. Our study found that significant increases exist in percent body fat during undergraduates' college years and that change differs for males and females. In addition, through the use of nested hierarchical models, eating regulation style (autonomous or controlled regulation), appearance schema (self-evaluative salience or motivational salience), and body satisfaction were identified as influential predictors of change in percent body fat. For example, young females, who do not feel in control of their physical appearance yet spend a great deal of time maintaining their appearance, have the highest initial body fat percentage and the steepest increase in percent body fat. Overall, males and females with high autonomous regulation and high motivational salience are likely to maintain (instead of increase) percent body fat over the college years. Knowing the influence of these predictors can be useful for promoting health and intervening with young adults in the college setting and other emerging adults who are not enrolled in postsecondary institutions.     

Exploring the link between pet abuse and controlling behaviors in violent relationships

Domestic violence is not as simple as one partner physically harming another. Instead, it consists of a complex range of controlling behaviors including physical, emotional, sexual, and economic maltreatment as well as isolation, male privilege, blaming, intimidation, threats, and minimizing/denying behaviors. In addition to the controlling behaviors reported by women seeking shelter from violent relationships, a growing body of research indicates some individuals who abuse their intimate partner also abuse their pets. This study explores these connections using reports of 1,283 female pet owners seeking refuge from their male batterer in a domestic violence shelter. Findings indicate that batterers who also abuse their pet (a) use more forms of violence and (b) demonstrate greater use of controlling behaviors than batterers who do not abuse their pets. Likewise, positive correlations are found between specific controlling behaviors and cruelty to pets. Implications for practice and future research are discussed.     

The Personal Vote and the Efficacy of Education Spending

In this article we explore the ways in which incentives to cultivate a personal vote affect the efficiency of education spending in developing democracies. We argue that where the electoral system provides incentives for political particularism, resources are allocated less efficiently and the effect of increased spending on literacy is diminished. We test our hypotheses using data on education spending and performance in over 40 developing democracies since 1980. We find that though personal vote systems spend just as much on education as party vote systems, particularism in personal vote systems dampens the marginal effect of increased education spending on illiteracy and at its highest levels, incentives to cultivate a personal vote completely undermine the positive effects of increased education spending on literacy.     

The role of citizens in the “soft law” of select social policy areas in Canada and the European Union

This article compares the role of citizens in public reporting exercises of Canada's National Child Benefit and health care service delivery to that of the European Union's open method of coordination (OMC) for social protection and social inclusion. It finds that the institutional infrastructure providing for coordination across social policy areas and possible roles for non‐governmental actors in policy development is more extensive in the OMC than in the “new modes of governance” in Canada. However, there are obstacles to developing such infrastructure in Canada, given the different histories and political contexts of the European community and the functioning of federalism in Canada.     

If it Weren't for Those ?∗!&∗@!∗ Nader Voters we Wouldn't Be in This Mess: The Social Determinants of the Nader Vote and the Constraints on Political Choice

Much has been written about the effect of Ralph Nader's recent experience in Presidential politics—in particular about the consequential election of 2000. The general view is that Nader's direct effect on that contest was to cost Gore the election and the indirect effect was to undermine popular and professional support for third-party challenges from the left. In this paper, we revisit this debate by contrasting Nader voters with both Nader-supporting Gore voters and non-voters using data from the 2000 National Election Studies. In line with some predictions, we find that the Nader voters had a tendency to come from privileged positions in terms of income and occupation and to embrace consistently progressive policy positions. More surprising is the fact that Latino voters were disproportionately attracted to Nader and that Nader voters were mobilized to vote in numbers far higher than has been previously reported. This mobilization effect is also evident in Nader-supporting Gore voters under the age of 34. A final analysis suggests that little separates those Nader voters who were divided in their support for Gore.
