A validation study for vinyl electrical tape end matches

Fracture matches are considered the strongest conclusion in the forensic examination of rigid materials, such as glass, metal, and paint. However, publications that support the fracture matching of polymeric films, such as tape backings, are limited. This study was designed to determine the validity and error rate associated with conducting end-match (fracture match) examinations on vinyl electrical tape. Test designs varied the source roll of tape, test preparer, or mode of separation from the roll. Results indicated that each affected the resulting severed tape ends. The analysts examining the end matches also had an effect on the results. Eight end matches in the study were not identified by the initial analysts and were considered inconclusive. One end match was misidentified, resulting in one false positive and an error rate of 0.049%. These results support a comprehensive physical and chemical tape comparison regardless of indications of an end match.     

Pulling the Levers: Transformational Leadership,Public Service Motivation,and Mission Valence

This article contributes to our understanding of public service motivation and leadership by investigating ways in which organizational leaders can reinforce and even augment the potential effects of public service motivation on employees’ attraction to the organization’s mission (mission valence). The results contribute to two research questions. First, the findings provide new evidence on the sources of public service motivation. The authors find that transformational leadership is an organizational factor associated with higher public service motivation. Second, the article examines the relationship between transformational leadership and mission valence. The authors find that transformational leadership has an important indirect effect on mission valence through its influence on clarifying organizational goals and fostering public service motivation.     

Genetic and Environmental Overlap between Low Self-Control and Delinquency

Low self-control has emerged as a consistent and strong predictor of antisocial and delinquent behaviors. Using the twin subsample of the National Longitudinal Study of Adolescent Health (Add Health), genetic analyses were conducted to examine the genetic and environmental contributions to low self-control and offending as well as to their relationship with one another. The results revealed that low self-control and criminal behaviors are influenced by genetic and nonshared environmental factors with the effects of shared environmental factors being negligible. In addition, the co-variation between low self-control and criminal behaviors appears to be largely due to common genetic and nonshared environmental factors operating on both phenotypes. The implications of these findings on the current understanding of Gottfredson and Hirschi??s general theory of crime are discussed.     

Catching flies with vinegar: a critique of the Centers for Medicare and Medicaid self-disclosure program

This Article argues that the current approach of the Department of Health and Human Services and the Centers for Medicare and Medicaid Services (CMS) to enforcement of the Ethics in Patient Referrals Act (the "Stark Law") is unnecessarily punitive and discourages health-care providers from self-disclosing even very minor violations of the Stark Law. This Article suggests a number of specific changes to encourage provider self-disclosure and proposes that CMS create a demonstration project under the authority of the Patient Protection and Affordable Care Act to test the reforms. A demonstration project provides the perfect vehicle to prove that increased self-disclosure protocols for the Stark Law can decrease the government's costs of enforcement, improve program integrity, and encourage providers to deal responsibly with the inevitable minor lapses in compliance that arise in such an enormous government program as Medicare.     

Anatomy of a government massacre: Abuses of hostage‐barricade protocols during the Waco standoff

A systematic evaluation of the FBI's crisis negotiations with the Branch Davidians during a 51‐day standoff in 1993 is conducted. The analysis uncovers extensive violations of basic hostage‐barricade standards and protocols. The violations appear shortly after negotiations began indicating a premature disregard for the publicly declared goal of a peaceful resolution. Failed negotiations subsequently were cited by FBI officials as a rationale for organizing a violent and dangerous CS gas assault on the barricaded group, resulting in the destruction of the religious community and the deaths of 74 people. The violations do not appear to be random, incidental, or the result of disorganization, as officials claim. The data indicate that the FBI's on‐scene commanders and tactical component of the Hostage‐Rescue Team (HRT) contributed largely to the failed negotiations through methods of increased tactical pressure and psychological warfare providing justification for the high‐risk assault. The thesis is advanced that the HRT command may have pursued furtively what some insiders call a ‘Western’ view of hostage‐barricade incidents ‐ i.e., that negotiations should be used as a means of manipulating people into positions where a tactical solution can be executed. In this context, the standoff is analyzed as a government massacre. Possible motives for this state violence are linked to the sect's defiant posture, aspects of police culture, effective demonization of the sect, and the disturbing trend of ‘militarization’ within law enforcement.     

Sobering Up on the Streets: Homeless Men in Alcoholics Anonymous

An exploratory, qualitative examination of homeless, recovering alcoholic men in a Twelve-Step program shows the ways these men adapt tools of sobriety to match their needs. Using semi-structured interviews, the experiences of these men were evaluated in order to find out how they stay sober without a formal place to live. Based on the narrative histories, three varieties of adaptations to the conventional Alcoholics Anonymous program are discussed: excessive twelfth-stepping, a mélange of religious principles, and unrealistic ideals. Implications for treatment and directions for future research are discussed.     

Commonwealth Engagement in Education: Prospects in the Era of SDGs

ABSTRACT

This paper analyses Commonwealth engagement in education against a background of issues, trends, and partnerships in education. It argues for reforms towards a ‘New Commonwealth’ that is fit for the 21^st century; embracing the celebration of diversity and moving beyond the donor/recipient model of development. The relevance, effectiveness, and sustainability of education engagement by the Commonwealth are gauged in relation to the focus of the sustainable development goals (SDGs) on the indigenous, immigrant, refugee, and other disadvantaged populations. The paper explores education challenges facing these population groups and proposes some options or niche areas that may be considered for Commonwealth engagement in education. The first option is engagement in the influential Global Partnership for Education (GPE), where Commonwealth countries already operate, and synergies are possible with UNICEF, UNESCO, and the World Bank. Second is pan-Commonwealth ‘facilities’ for implementing bi-lateral projects. Third is Commonwealth Talent Academies to address youth unemployment and illegal migration. Fourth is using COL to enhance distance learning leadership. Fifth is a Commonwealth Teachers Exchange Scheme to ‘right-size’ teaching forces. Sixth is the Commonwealth Remittances Transaction Cost Reduction initiative. Viability of these options will depend on the appetite for reform towards a multi-polar Commonwealth with financial burden sharing.     

Development of a human-specific real-time PCR assay for the simultaneous quantitation of total genomic and male DNA

A duplex real-time quantitative PCR assay was developed for forensic DNA analysis, which provides simultaneous quantitation of total genomic human DNA and human male DNA. The assay utilizes two spectrally resolved fluorogenic probes in a 5' nuclease (TaqMantrade mark) assay. Within the range of organisms empirically tested and based upon theoretical specificity using National Center for Biotechnology Information GenBank sequences, primer and probe sequences were shown to be human specific, and the Y-chromosome probe, male-specific. A mixture-challenge study resulted in accurate quantitation of 25 pg male DNA in a mixture of up to 1:5000 (male:female DNA). Additional experimental results include comparisons with the slot blot method and commercial real-time PCR kits. The assay developed addresses the shortcomings of the traditional slot blot method as well as the commercial real-time PCR kits. This method is shown to be specific, relatively simple, rapid, has low limits of detection, and consumes limited sample in addition to reporting both the male and total genomic DNA concentrations present.
