Effects of Cyanoacrylate Fuming,Time After Recovery,and Location of Biological Material on the Recovery and Analysis of DNA from Post‐Blast Pipe Bomb Fragments*

Abstract: This study investigated the effects of time, cyanoacrylate fuming, and location of the biological material on DNA analysis of post‐blast pipe bomb fragments. Multiple aliquots of a cell suspension (prepared by soaking buccal swabs in water) were deposited on components of the devices prior to assembly. The pipe bombs were then deflagrated and the fragments recovered. Fragments from half of the devices were cyanoacrylate fumed. The cell spots on the fragments were swabbed and polymerase chain reaction/short tandem repeat analysis was performed 1 week and 3 months after deflagration. A significant decrease in the amount of DNA recovered was observed between samples collected and analyzed within 1 week compared with the samples collected and analyzed 3 months after deflagration. Cyanoacrylate fuming did not have a measurable effect on the success of the DNA analysis at either time point. Greater quantities of DNA were recovered from the pipe nipples than the end caps. Undeflagrated controls showed that the majority (>95%) of the DNA deposited on the devices was not recovered at a week or 3 months.     

Skull-photo superimposition and border deaths: identification through exclusion and the failure to exclude

We report on the application of video skull-photo superimposition as an identification method in a case from Ajo, Arizona in which five individuals died after crossing into southern Arizona from Mexico. Initial analyses at the Pima County Forensic Science Center in Tucson, Arizona determined that the disarticulated skeletal remains represented two adult Hispanic males and three adult Hispanic females. Based on biological profiles, both the males and one of the females were tentatively identified and assigned names. The other two females were too similar in age and height, making skeletal separation and identification difficult. As a result, the Michigan State University Forensic Anthropology Laboratory assisted in the identification efforts by performing video skull-photo superimposition on the two unknown females. The skulls were compared to a photograph reported to be one of the missing females. By evaluating facial proportionality and by comparing a number of morphological features of the face and skulls, one skull was excluded as a possible match and one skull was not excluded as a match to the antemortem photo. Because this case was presumed to be a closed disaster, the exclusion of one skull and the failure to exclude the other represented circumstantial identifications.

Fighting World War III: A suggested strategy

Abstract

Utilizing a rational‐actor policymaker model, this paper presents the necessary and sufficient conditions that must be satisfied for the formation of a transnational antiterrorist institution. Such an institution would tie together nations in their struggle against international terrorism. In particular, these institutions could provide crisis management, preemptive strikes, and retaliatory strikes. After analyzing the obstacles to the formation of such institutions, we present a specific proposal for a transnational commando unit. We chose the parameters of the proposed institution so as to maximize the likelihood of initial formation. In addition, we discuss how the transnational commando unit could, if properly designed, surmount the obstacles to formation. As terrorist groups increase their cooperation and stage incidents of a transnational kind, nations will have to turn to such institutions to increase the effectiveness of commando units, eliminate safe havens, and share intelligence. Although our proposal is more modest than those often put forth, once formed, our institution could evolve over time.     

Invariance of Measures of Prevention Program Effectiveness: A Replication

Recent literature has suggested that measures of risk and protective factorsfor delinquency and substance use are not equally reliable or valid acrossgender and ethnic groups and has recommended differentiated programming andculturally specific evaluation methods. Three data sets containing up tofive ethnic groups were used to determine the degree to which risk andprotective factors are equally reliable and valid predictors of drug use anddelinquency across gender and ethnic groups. Congeneric measurement modelsand structural equation models were evaluated to determine if the factorstructures for these measures and their covariances with measures of druguse and delinquency were equivalent across gender and ethnic groups. Half ofthe risk and protective factors included in this analysis were found to beequally reliable across gender and ethnic groups. When controlling forreliability differences, all of the risk and protective factors were foundto predict both drug use and delinquncy for all gender and ethnic groups. Interms of the magnitude of these associations, no substantive differenceswere found in the validity of risk and protective factors for drug use anddelinquency. Differences in the validity of risk and protective factors weremore prevalent for delinquency than for drug use. However, all differenceswere substantively trivial. We conclude that measures of prevention programeffectiveness are invariant across gender and ethnic groups.     

Multiple Identification and Risks: Examination of Peer Factors Across Multiracial and Single-Race Youth

Multiracial youth are thought to be more vulnerable to peer-related risk factors than are single-race youth. However, there have been surprisingly few well-designed studies on this topic. This study empirically investigated the extent to which multiracial youth are at higher risk for peer influenced problem behavior. Data are from a representative and longitudinal sample of youth from Washington State (N?=?1,760, mean age?=?14.13, 50.9% girls). Of those in the sample, 225 youth self-identified as multiracial (12.8%), 1,259 as White (71.5%), 152 as Latino (8.6%), and 124 as Asian American (7.1%). Results show that multiracial youth have higher rates of violence and alcohol use than Whites and more marijuana use than Asian Americans. Higher levels of socioeconomic disadvantage and single-parent family status partly explained the higher rates of problem behaviors among multiracial youth. Peer risk factors of substance-using or antisocial friends were higher for multiracial youth than Whites, even after socioeconomic variables were accounted for, demonstrating a higher rate of peer risks among multiracial youth. The number of substance-using friends was the most consistently significant correlate and predictor of problems and was highest among multiracial youth. However, interaction tests did not provide consistent evidence of a stronger influence of peer risks among multiracial youth. Findings underscore the importance of a differentiated understanding of vulnerability in order to better target prevention and intervention efforts as well as the need for further research that can help identify and explain the unique experiences and vulnerabilities of multiracial youth.     

Individual and Contextual Predictors of Cyberbullying: The Influence of Children’s Provictim Attitudes and Teachers’ Ability to Intervene

Electronic social communication has provided a new context for children to bully and harass their peers and it is clear that cyberbullying is a growing public health concern in the US and abroad. The present study examined individual and contextual predictors of cyberbullying in a sample of 16, 634 students in grades 3–5 and 7–8. Data were obtained from a large cluster-randomized trial of the KiVa antibullying program that occurred in Finland between 2007 and 2009. Students completed measures at pre-intervention assessing provictim attitudes (defined as children’s beliefs that bullying is unacceptable, victims are acceptable, and defending victims is valued), perceptions of teachers’ ability to intervene in bullying, and cyberbullying behavior. Students with higher scores on provictim attitudes reported lower frequencies of cyberbullying. This relationship was true for individual provictim attitudes as well as the collective attitudes of students within classrooms. Teachers’ ability to intervene assessed at the classroom level was a unique, positive predictor of cyberbullying. Classrooms in which students collectively considered their teacher as capable of intervening to stop bullying had higher mean levels of cyberbullying frequency. Our findings suggest that cyberbullying and other indirect or covert forms of bullying may be more prevalent in classrooms where students collectively perceive their teacher’s ability to intervene in bullying as high. We found no evidence that individual or contextual effects were conditional on age or gender. Implications for research and practice are discussed.     

Features of objectified body consciousness and sociocultural perspectives as predictors of eating and body image disturbances among young women and men in China

Body surveillance and body shame are features of objectified body consciousness that have utility in predicting body image and eating disturbances but evidence is based largely on samples in developed Western nations and it is not clear whether these factors predict disturbances independent of conceptually-related factors emphasized in alternate sociocultural accounts. To address these issues, we assessed the impact of body surveillance and body shame as well as features of other sociocultural models (i.e. perceived appearance pressure, appearance comparisons, general negative affect) on disordered eating, fatness concerns, and body dissatisfaction among young Chinese adults. University-age women (n = 466) and men (n = 230) from Chongqing, China completed validated self-report measures of demographics and the above constructs. For women, objectified body consciousness measures explained significant variance in each measure of disturbances, beyond effects of other factors; body surveillance had a unique impact in each prediction model. For men, facets of objectified body consciousness also combined for unique variance across prediction models, though body shame was the more prominent unique influence. Findings highlight the potential role of individual differences in body surveillance and body shame as influences on eating and body image of young women and men within a Chinese context.
