Trends in explosive contamination

This study sought to assign a rough order of magnitude for the amount of explosive residue likely to be available in real-world searches for clandestine explosives. A variety of explosives (TNT, TATP, HMX, AN, RDX, PETN) in various forms (powder, flake, detonating cord, plastic) were carefully weighed or cut into containers, and the amount of residue inadvertently remaining on the work area, hands, or containers was quantified. This was used to evaluate the spillage potential of each explosive. The adhesion of each explosive to a glass surface was quantified from amount of explosive adhering to the inside of a glass vial into which the explosive had been placed and then removed by vigorous tapping. In powdered form, most of the explosives--TNT, PETN, RDX, HMX, and TATP--exhibited similar spillage and adhesion to glass. However, PETN as sheet explosive and plasticized RDX (C-4), showed very little potential to contaminate surfaces, either by spillage or adhesion to glass.     

Perceptions of Law Enforcement Officers in Seeking Mental Health Treatment in a Right-to-Work State

The high stress environment of law enforcement places officers at risk for a variety of mental and physical health problems; however, officers are reluctant to seek out treatment. The purpose of this study was to identify which factors associated with law enforcement officers had predictive value in the level of stigma perceived in seeking mental health treatment by currently employed, certified peace officers in Arizona. The factors included sex, age, race/ethnicity, years employed as an officer, size of the department, current rank/position within the department, the type of government operating the agency, and payment of union dues. The study included 454 participants. Participation included the completion of demographic data, the Self-Stigma of Seeking Psychological Help (SSOSH), and the Perceptions of Stigmatization by Others for Seeking Help (PSOSH). Using standard multiple regression, the most significant finding was the relationship between the size of the department and levels of stigma (p = .014); such that, the size was inversely related to the levels of perceived stigma. As the agency size increased, the perceptions of stigma decreased. Such a finding has several implications for law enforcement agencies related to preparedness and training.     

Recognition and Social Justice: What Critical Theory Can Learn From Paid Domestic Laborers in the United States

Working in private homes, often isolated from the community and denied the legal rights and protections that most other workers enjoy, paid domestic laborers make up some of the most socially marginalized, vulnerable, and exploited workers in the United States today. This article explores the theoretical possibilities for an account of justice, based on the concept of recognition, to critique their work experiences, legal exclusion, and social status. To do so, it draws on the contrasting accounts of recognition advanced by Axel Honneth and Nancy Fraser, which focus on the psychological and the socio-structural dimensions of recognition respectively. While both theories generate compelling critiques of the conditions of domestic laborers, it is shown that neither one alone can capture the full range of injustices experienced, and that each can in fact complement the other. The article thus sketches an account of justice based on both the psychological and socio-structural dimensions of recognition.     

Population structure of Y chromosome SNP haplogroups in the United States and forensic implications for constructing Y chromosome STR databases

A set of 61 Y chromosome single-nucleotide-polymorphisms (Y-SNPs) is typed in a sample of 2517 individuals from 38 populations to infer the geographic origins of Y chromosomes in the United States and to test for paternal admixture among African-, European-, Hispanic-, Asian-, and Native-Americans. All of the samples were previously typed with the 11 core U.S. Y chromosome short tandem repeats (Y-STRs) recommended by SWGDAM, which revealed high levels of among ethnic group variation and low levels of among-population-within-ethnic-group variation. Admixture estimates vary greatly among populations and ethnic groups. The frequencies of non-European (3.4%) and non-Asian (4.5%) Y chromosomes are generally low in European-American and Asian-American populations, respectively. The frequencies of European Y chromosomes in Native-American populations range widely (i.e., 7-89%) and follow a West to East gradient, whereas they are relatively consistent in African-American populations (26.4+/-8.9%) from different locations. The European (77.8+/-9.3%) and Native-American (13.7+/-7.4%) components of the Hispanic paternal gene pool are also relatively constant among geographic regions; however, the African contribution is much higher in the Northeast (10.5+/-6.4%) than in the Southwest (1.5+/-0.9%) or Midwest (0%). To test for the effects of inter-ethnic admixture on the structure of Y-STR diversity in the U.S., we perform subtraction analyses in which Y chromosomes inferred to be admixed by Y-SNP analysis are removed from the database and pairwise population differentiation tests are implemented on the remaining Y-STR haplotypes. Results show that low levels of heterogeneity previously observed between pairs of Hispanic-American populations disappear when African-derived chromosomes are removed from the analysis. This is not the case for an unusual sample of European-Americans from New York City when its African-derived chromosomes are removed, or for Native-American populations when European-derived chromosomes are removed. We infer that both inter-ethnic admixture and population structure in ancestral source populations may contribute to fine scale Y-STR heterogeneity within U.S. ethnic groups.     

‘Dancing with the prince’: Ngo's survival strategics in the Afghan conflict

Afghan NGOs have been a major provider of humanitarian aid throughout the Afghan conflict. They remained operational during this period by 'dancing' with and between the various parties to the conflict, their survival contingent on their ability to build ad hoc patterns of alliance and cooperation. This article explores the nature of 'the dance' between NGOs, the warring parties, and the NGOs' constituencies. It asks whether 'dancing with the prince' represents an accommodation with violence or is a necessary compromise which will ultimately contribute to resolving the conflict. It concludes by drawing out key lessons for donors who support indigenous NGOs operating in complex political emergencies.     

Mass Reentry,Neighborhood Context and Recidivism: Examining How the Distribution of Parolees Within and Across Neighborhoods Impacts Recidivism

Recent scholarship focuses on the role neighborhood context plays in reoffending. These studies lack an examination of how the size of the parolee population at the neighborhood-level impacts individual recidivism. We examine how the size and clustering of parolee populations within and across neighborhoods impacts individual-level recidivism. Using data from parolees returning to three Ohio cities from 2000 to 2009, we examine how concentrations of parolees in neighborhoods and in the surrounding neighborhoods impact the likelihood of reoffending. We also examine whether parolee clustering conditions the relationship between neighborhood-level characteristics and recidivism. Results show concentrated reentry increases recidivism, while parolees in stable neighborhoods are less likely to recidivate. Also, the positive effect of parolee concentration is tempered when parolees return to stable neighborhoods. These findings suggest that augmenting resources available in neighborhoods saturated by parolees, as well as bolstering residential stability in these same neighborhoods might reduce reoffending.     

The Praxis Assignment: Experiential Learning in a Large Social–Community Psychology Class

In this article, a faculty member, a graduate student teaching assistant, and four undergraduates describe their experiences with a “Day of Social Justice Praxis Assignment” as a form of experiential learning in a 120-person social-community psychology course. The faculty member lays out the goals of the course and her hopes for the specific assignment. The undergraduates reflect on their experience with the assignment, and the graduate student contextualizes how their work is reflective or not reflective of the work produced in the class and course concepts. The article ends with a critical and frank discussion of the benefits and drawbacks of the assignment.
