Getting Out the Vote: Minority Mobilization in a Presidential Election

Despite attempts to mobilize communities of color, gaps in turnout among racial and ethnic minorities persist (e.g., Abrajano et al., J Polit 70:368–382, 2008; Pantoja et al., Polit Res Q 54:729–750, 2001; Kaufmann, Polit Res Q 56:199–210, 2003; Ramirez, Ann Am Acad Pol Soc Sci 601:66–84, 2005, Am Polit Res 35:155–175, 2007). Scholars are only beginning to understand how parties or independent groups seek to mobilize these communities. In this paper, we develop and test the Differential Contact Thesis, which holds that turnout differences between whites and minority groups are influenced both by lower rates of contact by the parties and the use of less effective methods of contact. To test this, we examine data from the 2004 National Annenberg Election Study (NAES), 2004 American National Election Study (ANES), and the 2004 Miami Exit Poll. Our results support the Differential Contact Thesis: even controlling for the initial likelihood to be contacted by the parties, racial and ethnic minorities were less likely to be contacted using the most effective techniques. To some extent, non-partisan contact seems to compensate for the inattention of the major parties toward minority voters, but this contact is less likely to mobilize voters than contact from the parties.     

A radiographic assessment of pediatric fracture healing and time since injury

Past studies and pediatric bone physiology indicate that younger individuals may heal at a faster rate. Additionally, in adults upper limb fractures heal faster than lower limb fractures; this trend is expected for pediatric fractures. This study aims to evaluate and compare rates of fracture repair in children based on age and skeletal element. Six stages are used to describe the bone repair process in 294 radiographs of tibial and radial fractures from 107 infants and young children. Healing rates are examined using ANOVA and Welch's t-test with a 95% confidence interval. Results indicate that younger individuals spend less time at stage 1, suggesting a delay in the start of healing. Furthermore, forearm fractures heal faster than leg fractures at stages 2 and 3, suggesting a role in the osseous reaction of bone healing. The healing schedule presented may allow the timing of injuries to be estimated from radiographs.     

Confocal microscopy analysis of breech face marks on fired cartridge cases from 10 consecutively manufactured pistol slides

Recent publications from the National Academy of Sciences have called for additional foundational research in the field of firearm and toolmark analysis. We examined test fires from 10 pistol slides with consecutively manufactured breech faces. A total of nine test fires from each pistol slide, for a total of 90 test fired cartridge cases, were compared using confocal microscopy combined with three-dimensional cross-correlation analysis algorithms. A total of 8010 comparisons were performed (720 matches and 7290 nonmatches). The average score for matches was 0.82 with a standard deviation of 0.06. The average score for nonmatches was 0.20 with a standard deviation of 0.03. Additionally, subclass toolmarks were observed on the breech faces, but the presence of subclass was not detected in the correlation analysis. There was no overlap of scores between matching and nonmatching test fires. This provides objective data that support the AFTE (Association of Firearms and Tool Mark Examiners) theory of identification.     

Reasonable Grounds Evidence Involving Sexual Violence in Darfur

Internal and international conflicts can often involve a level of impunity that allows sexual violence to persist unchecked by military and political leaders. The recent reversal by an appeals panel at the International Criminal Court of a pretrial decision not to charge President al-Bashir of Sudan with genocide in Darfur offers an important foundation for introducing new types of evidence that can increase the investigation and prosecution of sexual violence during conflicts. The reversal cited the incorrect use of the “beyond a reasonable doubt” standard when the lesser standard of “reasonable grounds” applied. Social science provides methods and measures that can be uniquely used to develop reasonable grounds evidence, for example, to demonstrate the roles of physical perpetrators acting together in horizontal relationships, as well as to establish the indirect participation through vertical relationships of higher-level defendants, in a chain of command of superior responsibility. We illustrate these points by presenting social science evidence of the responsibility of President al-Bashir and middle- and lower-level figures in genocidal violence in Darfur.     

The Effects of Child Abuse and Exposure to Domestic Violence on Adolescent Internalizing and Externalizing Behavior Problems

This study examines the effects of child abuse and domestic violence exposure in childhood on adolescent internalizing and externalizing behaviors. Data for this analysis are from the Lehigh Longitudinal Study, a prospective study of 457 youth addressing outcomes of family violence and resilience in individuals and families. Results show that child abuse, domestic violence, and both in combination (i.e., dual exposure) increase a child’s risk for internalizing and externalizing outcomes in adolescence. When accounting for risk factors associated with additional stressors in the family and surrounding environment, only those children with dual exposure had an elevated risk of the tested outcomes compared to non-exposed youth. However, while there were some observable differences in the prediction of outcomes for children with dual exposure compared to those with single exposure (i.e., abuse only or exposure to domestic violence only), these difference were not statistically significant. Analyses showed that the effects of exposure for boys and girls are statistically comparable.     

Assessing Impact Direction in 3‐point Bending of Human Femora: Incomplete Butterfly Fractures and Fracture Surfaces,,

Current literature associates bending failure with butterfly fracture, in which fracture initiates transversely at the tensile surface of a bent bone and branches as it propagates toward the impact surface. The orientation of the resulting wedge fragment is often considered diagnostic of impact direction. However, experimental studies indicate bending does not always produce complete butterfly fractures or produces wedge fragments variably in tension or compression, precluding their use in interpreting directionality. This study reports results of experimental 3‐point bending tests on thirteen unembalmed human femora. Complete fracture patterns varied following bending failure, but incomplete fractures and fracture surface characteristics were observed in all impacted specimens. A flat, billowy fracture surface was observed in tension, while jagged, angular peaks were observed in compression. Impact direction was accurately reconstructed using incomplete tension wedge butterfly fractures and tension and compression fracture surface criteria in all thirteen specimens.     

Never lost a penny: An assessment of federal deposit insurance

Current problems of the Federal deposit insurance system threaten not only to increase future Federal costs but also to destabilize the U.S. banking system as it faces new competitors. The system's problems can be traced to weakness in both the political and market feedback mechanisms. Current policies governing Federal deposit insurance are flawed in numerous respects. Recent extension of capital forbearance to troubled institutions appears to be another step in the wrong direction. Reforms are suggested that would improve political accountablity and market discipline. However, given resistance to such reforms, only a banking crisis seems likely to break the impasse.     

The effect of Japanese corporate acquisition on the us military-industrial base

This paper utilizes a technique called the analysis of competing hypotheses to study Japanese acquisitions that involve majority interests in US firms. Findings show that there seem to be strategic trends in the Japanese procurement process, and that there are four domestic product groups that appear to be particularly vulnerable. Such foreign control of American commercial enterprises may well be a threat to the economy and national security.
