Spatial and temporal influences on bacterial profiling of forensic soil samples

Bacterial content may be helpful in differentiating forensic soil samples; however, the effectiveness of bacterial profiling depends on several factors, including uniqueness among different habitat types, the level of heterogeneity within a habitat, and changes in bacterial communities over time. To examine these, soils from five diverse habitats were tested over a 1 year period using terminal restriction fragment length polymorphism (TRFLP) analysis. Soil samples were collected at central locations monthly, and 10 feet in cardinal directions quarterly. Similarity indices were found to be least related among habitats, while the greatest bacterial similarities existed among collection locations within a habitat. Temporally, however, bacterial content varied considerably, and there was substantial overlap in similarity indices among habitats during different parts of the year. Taken together, the results indicate that while bacterial DNA profiling may be useful for forensic soil analysis, certain variables, particularly time, must be considered.     

Particle Analysis for the Detection of Gunshot Residue (GSR) in Nasal Samples Using Scanning Laser Ablation and Inductively Coupled Plasma-Mass Spectrometry (SLA-ICPMS)

Currently, aluminum stub with carbon adhesive devices are used to collect inorganic gunshot residues (GSR) from the hands of a shooter. In an ideal shooting case, the gunshot particles do not persist for more than 2 h in the hands of the shooter, provided that the hands have not been washed. However, for forensic analysis and inference, the extended persistence of GSR would be desirable. This study investigates a novel GSR sampling and detection protocol. Sampling was performed in the nostrils using swab devices impregnated in ethylenediaminetetraacetic acid (EDTA). The GSRs persisted for longer periods in nasal mucus than on the hands, and particles were detected 6 h after shooting occurred. The analytical determination was conducted by scanning laser ablation-inductively coupled plasma-mass spectrometry (SLA-ICPMS) which enable the identification of the number of particles and their elemental composition. Seventeen isotope signals corresponding to ¹³C, ²⁰⁵Tl and 15 analytes that are usually associated with the composition of GSR residues were monitored: ²⁷Al, ²⁹Si, ³¹P, ³³S, ³⁵Cl, ³⁹K, ⁴⁴Ca, ⁵⁷Fe, ⁶⁰Ni, ⁶³Cu, ⁶⁶Zn, ¹¹⁸Sn, ¹²¹Sb, ¹³⁷Ba, and ²⁰⁸Pb. The SLA technique enabled the reduction of the swab analysis time to 40 min. The effectiveness of this methodology was evaluated with two types of firearms: a pistol and a shotgun. The results indicated that the methodology proposed for the analysis of the nasal GSR was effective and that it can improve or complement the forensic analyses and inferences presented in a court.     

Ourtown for teens: Long-term impact of a youth diversity program

This study fills a gap in the literature in regards to the effectiveness of youth diversity programs by exploring the sustaining effects of a week-long youth diversity camp program. Using both qualitative and quantitative methods, the study results suggest the camp achieved positive, sustaining impacts. Some of these findings include (1) enhancement of leadership skills; (2) greater understanding of “the other”; and (3) increased communication skills, particularly when oppression was observed. These effects were observed in the respondents who had recently attended the camp, as well as those who had attended a long time prior. Such impact reported in the study reiterates that more diversity programs for youth should be developed, implemented, and evaluated.     

What is “prison culture”? Developing a theoretical and methodological foundation for understanding cultural schema in prison

What does it mean to say that a prison has a “culture?” Scholars have long emphasized the presence of a “prison code” and, more recently, a “racial code” as salient cultural domains in men's prisons. Yet, even though most people intuitively understand what is meant by “prison culture,” little progress has been made regarding the conceptualization and operationalization of culture as an analytical construct in prison scholarship. The current study makes two primary contributions to this literature. First, drawing on advances in anthropology, cultural sociology, and cognitive science, we incorporate the concept of cultural schema to provide a concrete analytical construct. Second, we test varying conceptualizations of cultural schema as either characterized by consensus or as overlapping relational structures. Using cultural consensus and correlational class analyses among a sample of 266 incarcerated men, we find little evidence of a culture of consensus for either the prison code or the racial code. Furthermore, we show evidence of heterogenous schema among these cultural domains. Our study is relevant to wider disciplinary work on culture as the problem of analytical precision we address is characteristic of much of the work in criminology and criminal justice that evokes culture as an explanatory device.     

Comparing Welfare Service Delivery Among Public,Nonprofit and For-Profit Work Agencies

Since passage of the Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA) in 1996, there has been a proliferation of contracting for welfare services, specifically around Temporary Assistance for Needy Families (TANF) and related benefits and services such as child care. The services most commonly contracted include those around the work or employment function, such as training, education, job placement, and support services to promote job entry or retention.

The purpose of this article is to examine differences in the quality of service provision among public, nonprofit, and for-profit auspices in the delivery of work-based welfare reform services. The findings show that there are some differences in welfare programs across the three sectors. The significance of this issue relates to the critical question of whether social needs can be best met through competitive outsourcing.     

The violent reconvictions of sexual offenders

The violent reconvictions of a sample of sexual offenders discharged from prison between 1992 and 1996 (who had not been reconvicted of a sexual offence) were examined. The hypothesis was that a proportion of these violent reconvictions would have a sexual motivation. The sample consisted of 104 adult male sexual offenders for whom detailed information regarding their violent reconviction was available. The sample was categorized according to the motivation of the violent reconviction. It was found that a proportion of the violent reconvictions were sexually motivated (12%) and that some of these had resulted from an original charge for a sexual offence. Significant differences were found between the sexual motivation and violent motivation group on the number of criminal history and victim characteristic variables. It was concluded that, in the case of sexual offenders, violent convictions might mask the true motivation of the offence.     

Basic Personal Values Underlie and Give Coherence to Political Values: A Cross National Study in 15 Countries

Do the political values of the general public form a coherent system? What might be the source of coherence? We view political values as expressions, in the political domain, of more basic personal values. Basic personal values (e.g., security, achievement, benevolence, hedonism) are organized on a circular continuum that reflects their conflicting and compatible motivations. We theorize that this circular motivational structure also gives coherence to political values. We assess this theorizing with data from 15 countries, using eight core political values (e.g., free enterprise, law and order) and ten basic personal values. We specify the underlying basic values expected to promote or oppose each political value. We offer different hypotheses for the 12 non-communist and three post-communist countries studied, where the political context suggests different meanings of a basic or political value. Correlation and regression analyses support almost all hypotheses. Moreover, basic values account for substantially more variance in political values than age, gender, education, and income. Multidimensional scaling analyses demonstrate graphically how the circular motivational continuum of basic personal values structures relations among core political values. This study strengthens the assumption that individual differences in basic personal values play a critical role in political thought.
