Fatal positional asphyxia associated with rollover crashes

Motor vehicle rollover crashes result in complex occupant kinematics with the potential for severe injury. Five cases of fatal asphyxia in occupants suspended from their safety belt upside down after a rollover crash are presented. These fatalities accounted for 13.5% of all motor vehicle related asphyxia deaths in San Diego County over a 10-year period. This study supports previous research noting that incapacitation due to other injuries, alcohol, or obesity may be associated with fatal positional asphyxia due to inversion during rollovers. Safety belts are proven to prevent serious injury in motor vehicle crashes and should always be worn. However, redesign of the buckle could be considered to permit easier release by an occupant. We also suggest that pre-existing heart disease may contribute to the possibility of a fatal asphyxia outcome. Although this is a rare cause of motor vehicle related death, our results suggest that these are potentially preventable deaths.     

Promoting the Safe and Strategic Use of Technology for Victims of Intimate Partner Violence: Evaluation of the Technology Safety Project

The Technology Safety Project of the Washington State Coalition Against Domestic Violence was designed to increase awareness and knowledge of technology safety issues for domestic violence victims, survivors, and advocacy staff. The project used a “train the trainer” model and provided computer and Internet resources to domestic violence service providers in order to (1) increase safe computer and Internet access for domestic violence survivors in Washington; (2) reduce the risk posed by abusers by educating survivors about technology safety and privacy; and (3) increase the ability of survivors to help themselves and their children through information technology. Evaluation of the project suggests that the program is needed, useful, and effective. Consumer satisfaction was high and there was perceived improvement in computer confidence and knowledge of computer safety. Areas for future program development and further research are discussed.     

The Working Alliance in Intervention for Partner Violence Perpetrators: Recent Research and Theory

The working alliance consists of therapist and client agreement on the goals and tasks of therapy, and the therapeutic bond. Measures of the working alliance, assessed during the course of therapy, have consistently predicted positive therapeutic change across various client populations and treatment approaches. This paper reviews recent research highlighting the importance of the working alliance with respect to treatment compliance and outcome in interventions for perpetrators of partner violence. The common promotion and use of confrontational intervention tactics in these interventions and the potentially negative impact of confrontational tactics on the working alliance is also discussed.     

Allele frequencies of six miniSTR loci in the population of Northern Portugal

A possible approach to try to recover information from degraded DNA is to reduce the size of the PCR products by designing primers that bind as close as possible to the STR repeat region, known as miniSTRs. Allele frequencies and forensic parameters for the six miniSTRs loci D1S1677, D2S441, D4S2364, D10S1248, D14S1434 and D22S1045 were investigated in a sample group consisting of 228 anonymous apparently healthy unrelated individuals living in North of Portugal. The results show that all loci were in Hardy–Weinberg equilibrium. The combined power of discrimination and power of exclusion for the six loci were 0.99999 and 0.9789, respectively. All but one (D4S2364) loci showed a moderate degree of polymorphism (observed heterozygosity >0.6). The allele sizes ranged between 66 and 118 bp in our population, which is beneficial for typing degraded samples than those of a commercial STR kit.     

The incidence and magnitude of the health costs of in-person schooling during the COVID-19 pandemic

Public Choice - The health costs of in-person schooling during the pandemic, if any, fall primarily on the families of students, largely owing to the fact that students significantly outnumber...     

Relationship Abuse and Victims’ Posttraumatic Stress Disorder Symptoms: Associations with Child Behavior Problems

This study examined associations among male-to-female physical and psychological relationship aggression, female partners’ PTSD symptoms, and behavior problems among the children (n = 62) of men enrolled in a treatment program for relationship abuse perpetration. Psychological aggression was a stronger predictor of child behavior problems than physical assault. Restrictive engulfment and hostile withdrawal behaviors evidenced the strongest bivariate associations with child behavior problems, and were the strongest predictors of this outcome when considering four distinct forms of psychological aggression together. Victim PTSD symptoms largely mediated the effects of psychological aggression on child behavior. Findings suggest that male-to-female psychological aggression and victim PTSD symptoms play an important role in understanding behavior problems among children living with male relationship abuse perpetrators. Portions of this work were presented at the annual convention of the Association for the Advancement of Behavior Therapy, New Orleans, Louisiana, November, 2004.     

Mediators of male violence toward female intimates

The purpose of this study was to compare perceived life stressors, alcohol usage, and perceived quality of the intimate relationship of a group of males who have abused their female intimate with a group who have no history of abuse toward their partner. Interviews were conducted with 42 men who were defined as violent and 50 men who were defined as nonviolent. Interviews consisted of various demographic and health questions as well as standardized instrumentation (Michigan Alcoholism Screen Test, Autonomy/Relatedness Scale, Life Experiences Survey, and Conflict-Tactics Scale). Student's t tests indicated that the two groups differed as a function of perceived life Stressors, perceived quality of the intimate relationship, race, and depression. Stepwise logistic regression indicated that higher perceived quality of the intimate relationship, black race, and greater depression were significant predictors of male violence toward female intimates.
