Determination of Fracture Patterns in Glass and Glassy Polymers,

The study of fractures of glass, glassy‐type materials, and plastic has long been of interest to the forensic community. The focus of this interest has been the use of glass and polymer fractures to associate items of evidence under the assumption that each fracture is different. Generally, it is well‐accepted that deviations exist; however, the emphasis has been on classifying and predicting fracture rather than determining that each fracture is different. This study documented the controlled fracture patterns of 60 glass panes, 60 glass bottles, and 60 plastic tail light lens covers using both dynamic impact and static pressure methods under closely controlled conditions. Each pattern was intercompared, and based on the limited specimens tested in this study, the results illustrate that the fracture patterns are different. Further repetitive studies, under controlled conditions, will be needed to provide more statistical significance to the theory that each fracture forms a nonreproducible fracture pattern.     

Emotion Regulation in Police Officers Following Distress: Effects of Tenure and Critical Incidents

This study focuses on the functionality of emotion regulation of police officers who have or have not experienced a work-related critical incident. Traumatic events experienced by police officers may have long-lasting and significant consequences, including health concerns, emotional difficulties, impairment in social functioning, and they may have an impact on work performance. The hypotheses outline the expected results to include higher scores for officers who had been involved in one or more critical incidents in emotional well-being concerns and more difficulties with emotion regulation as compared to officers who had not experienced a critical incident. The research design employs written instruments including the General Health Questionnaire-30 to measure general emotional well-being, the Impact of Events Scale to measure the impact of a past traumatic event, and the Difficulties in Emotion Regulation Scale to measure current problems with emotion regulation. Participants consist of 76 full-time police officers assigned to patrol in two police agencies. The findings, analyzed through analysis of variance, did not include significant differences between those groups as expected; however, there were unexpected findings. These findings were that although newer officers were less likely to have experienced one or more work-related critical incidents, they measured higher in measures of emotion regulation difficulties and concerns regarding emotional well-being than did the more tenured officers. The social implications of this study include increased officer and agency awareness and increased use of effective intervention. Implications for future study include the need to further explore emotional challenges that may be experienced by new police officers.     

Spontaneous Rupture of the Gall Bladder: An Unusual Forensic Diagnosis

Peritonitis secondary to spontaneous rupture/perforation of the gall bladder is a rare condition overall and is even less common in the forensic population. We report the case of a middle‐aged man who died from generalized peritonitis from gall bladder perforation due to acute acalculous cholecystitis. This condition usually occurs in critical patients with systemic illness, and although the exact pathogenesis remains unclear, the development of acalculous cholecystitis appears to be multifactorial. Antemortem diagnosis is reliant upon clinical presentation, laboratory data, and radiologic studies. Surgery and appropriate antibiotics are mainstays of treatment; however, there is an emerging role for minimally invasive procedures. Histopathologic features show significant overlap with the calculous type. Although increasing numbers of acalculous cholecystitis have been diagnosed in the critically ill, the fatal presentation of a perforated gall bladder following an undiagnosed case of acute acalculous cholecystitis is unusual in a nonhospitalized and ambulatory man.     

Compulsory voting and the dynamics of partisan identification

Compulsory rules are known to have far‐reaching effects beyond boosting electoral participation rates. This article examines the relationship between compulsory voting and partisan attachments. A theory of attachment formation and strength is engaged that argues that compulsory voting boosts the likelihood that one will identify with a party and, in turn, the strength of party attachments among identifiers. The statistical model accounts for both the hierarchical structure of the data (individuals in elections) and the dual nature of the dependent variable (individuals report a strength of attachment only for the party with which they identify). Using data from the Comparative Study of Electoral Systems, it is demonstrated that compulsory voting does indeed increase both the incidence and the strength of partisanship.
