Posttraumatic Stress Disorder Symptoms,Relationship Adjustment,and Relationship Aggression in a Sample of Female Flood Victims

This study tested a model examining the interrelationships among posttraumatic stress disorder (PTSD) symptoms, intimate relationship adjustment, and intimate relationship aggression in a sample of 205 adult female flood victims. At the bivariate level, higher PTSD symptoms were associated with higher physical and psychological aggression victimization, poorer relationship adjustment, and higher physical and psychological aggression perpetration. Results from structural equation modeling (SEM) analyses indicated that relationship aggression victimization influenced aggression perpetration directly, and in the case of physical aggression, indirectly through its relationship with PTSD symptoms and relationship adjustment. The influence of PTSD symptoms on physical aggression perpetration was fully explained by poorer relationship adjustment. These findings extend prior work from other traumatized populations documenting associations between variables reflecting PTSD symptomatology and indices of relationship functioning, and indicate a need for further investigation in this area of inquiry. This research was supported in part by a grant to Patricia A. Resick from the National Institute of Mental Health (1-R01-MH55542).     

Symptoms of trauma, perceptions of discrimination, and anger: a comparison between Australian indigenous and nonindigenous prisoners

Although the need for the development and provision of culturally appropriate rehabilitation programs for offenders is widely acknowledged, there is a lack of empirical data that can be used as a basis for the development of new programs. This article reports the findings of a comparison of indigenous and nonindigenous male prisoners on a range of measures relevant to the experience of anger by indigenous prisoners in Australia. The results suggest that indigenous participants are more likely to experience symptoms of early trauma, have greater difficulties identifying and describing feelings, and perceive higher levels of discrimination than nonindigenous prisoners. The implications of this work for the development of culturally appropriate and effective anger management programs for indigenous male prisoners are discussed.     

Modeling the Impact of Technical Change on Emissions Abatement Investments in Developing Countries

The cost of greenhouse gas (GHG) mitigation over time depends on both the rate of technical change in leading-edge technologies and the diffusion of knowledge and capabilities throughout international markets. This paper presents a framework developed by the U.S. Environmental Protection Agency (EPA) and RTI International (RTI) for incorporating technical change in non-CO₂ GHG mitigation projections over time. An engineering (bottom-up) approach is used to model technical change as a set of price and productivity factors that change over time as a function of technology advances and the location of developing countries relative to the technology efficiency frontier. S-shaped diffusion curves are generated, which demonstrate the maturity of the market for a given technology in a given region. The framework is demonstrated for coal mine methane mitigation technologies in the United States and China, but it is applicable for the full range of technology adoption issues.     

Other-Sex Friendships in Late Adolescence: Risky Associations for Substance Use and Sexual Debut?

Adolescents’ friendships with other-sex peers serve important developmental functions, but they may also facilitate engagement in problem behavior. This study examines the unique contributions of other-sex friendships and friends’ behavior to alcohol use, smoking, and initiation of sexual intercourse among late adolescent girls and boys. A total of 320 adolescents (53% girls; 33% racial/ethnic minorities) provided sociometric nominations of friendships annually in grades 10–12. Friendship networks were derived using social network analysis in each grade. Adolescents and their friends also reported on their alcohol use, smoking, and sexual debut at each assessment. After controlling for demographics, previous problem behavior, and friends’ behavior, other-sex friendships in 10th grade were associated with initiation of smoking among girls over the following year, and other-sex friendships in 11th grade were linked with lower levels of subsequent alcohol use among boys. Additionally, friends’ smoking and sexual experience in 10th grade predicted the same behaviors for all adolescents over the following year. Other-sex friendships thus appear to serve as a risk context for adolescent girls’ smoking and a protective context for adolescent boys’ drinking. Promoting mixed-gender activities and friendships among older high school students may be helpful in reducing males’ alcohol use, but may need to incorporate additional components to prevent increases in females’ smoking.     

Forensic acquisition and analysis of palm webOS on mobile devices

The emergence of webOS on Palm devices has created new challenges and opportunities for digital investigators. With the purchase of Palm by Hewlett Packard, there are plans to use webOS on an increasing number and variety of computer systems. These devices can store substantial amounts of information relevant to an investigation, including digital photographs, videos, call logs, SMS/MMS messages, e-mail, remnants of Web browsing and much more. Although some files can be obtained from such devices with relative ease, the majority of information of forensic interest is stored in databases on a system partition that many mobile forensic tools do not acquire. This paper provides a methodology for acquiring and examining forensic duplicates of user and system partitions from a device running webOS. The primary sources of digital evidence on these devices are covered with illustrative examples. In addition, the recovery of deleted items from various areas on webOS devices is discussed.     

Predictors of Child Behavior Problems among Children of Female Vietnam Veterans

This study examined the impacts of intimate partner aggression by female Vietnam veterans and their male partners on their children’s behavior problems (N = 100 children). Veteran and partner psychological distress were also examined as potential mediators of these relationships. Results indicated that physical and psychological aggression perpetration by both the female veteran and the male partner was associated with child behavior problems. Contrary to expectations, psychological distress in the veteran and partner was not associated with child behavior problems and did not mediate the effects of physical and psychological aggression on this outcome.
