Quality assurance testing of an explosives trace analysis laboratory--further improvements

The Forensic Explosives Laboratory (FEL) operates within the Defence Science and Technology Laboratory (DSTL) which is part of the UK Government Ministry of Defence (MOD). The FEL provides support and advice to the Home Office and UK police forces on matters relating to the criminal misuse of explosives. During 1989 the FEL established a weekly quality assurance testing regime in its explosives trace analysis laboratory. The purpose of the regime is to prevent the accumulation of explosives traces within the laboratory at levels that could, if other precautions failed, result in the contamination of samples and controls. Designated areas within the laboratory are swabbed using cotton wool swabs moistened with ethanol water mixture, in equal amounts. The swabs are then extracted, cleaned up and analyzed using Gas Chromatographs with Thermal Energy Analyzer detectors. This paper follows on from a previous published paper describing the regime and summarizing subsequent results from approximately 6 years of tests. Lessons learned and improvements made over the period are also discussed. Monitoring samples taken from surfaces within the trace laboratories and trace vehicle examination bay have, with few exceptions, revealed only low levels of contamination, predominantly of RDX. Analysis of the control swabs, processed alongside the monitoring swabs, has demonstrated that in this environment the risk of forensic sample contamination, assuming all the relevant anti-contamination procedures have been followed, is so small that it is considered to be negligible. The monitoring regime has also been valuable in assessing the process of continuous improvement, allowing sources of contamination transfer into the trace areas to be identified and eliminated.     

Bhaṭṭa Rāmakaṇṭha’s Elaboration of Self-Awareness (svasaṃvedana), and How it Differs from Dharmakīrti’s Exposition of the Concept

The article considers what happened to the Buddhist concept of self-awareness (svasa?vedana) when it was appropriated by ?aiva Siddhānta. The first section observes how it was turned against Buddhism by being used to attack the momentariness of consciousenss and to establish its permanence. The second section examines how self-awareness differs from I-cognition (ahampratyaya). The third section examines the difference between the kind of self-awareness elaborated by Rāmaka??ha (‘reflexive awareness’) and a kind elaborated by Dharmakīrti (‘intentional self-awareness’). It is then pointed out that Dharmakīrti avails himself not only of intentional self-awareness but also of reflexive awareness. Some remarks on the relationship between these two strands of Dharmakīrtian Buddhism are offered. The conclusion points out that although self-awareness occurs in Buddhism as inextricably linked with anātmavāda, the doctrine of no-self, and sākāravāda, the view that the forms we perceive belong not to external objects but to consciousness, it is used by Rāmaka??ha to refute both of these views. An appendix addresses the problem of how precisely to interpret Dharmakīrti’s contention that conceptual cognition is non-conceptual in its reflexive awareness of itself.     

Preparing Child Welfare Practitioners: Implications for Title IV-E Education and Training Partnerships

ABSTRACT

High rates of child welfare practitioner turnover remain a national problem with significant consequences. Title IV-E education and training programs prepare child welfare practitioners for this line of work with the intent that they will create long term careers. This study analyzed qualitative data from a 2016 statewide electronic survey launched to obtain frontline child welfare practitioner feedback about workforce turnover and assist the agency in retention efforts.

Practitioner insight resulted in 189 responses specifically related to improving the state’s Title IV-E supported education and training program–the “Academy.” A qualitative thematic analysis identified three main themes: making it more realistic and hands on (n = 104), needing additional training and specific content (n = 45), and feeling overwhelmed with the experience (n = 40). Practitioner feedback illustrated the existing tensions with using a blended model to educate and train the workforce. Implications for Title IV-E education and training partnerships are discussed.     

MOVING INTO GLOBAL COMPETITION: A Case Study of Alabama's Recruitment of Mercedes-Benz

Globalization is changing the game of economic development, but the emerging rules and optimal strategies remain somewhat unclear. The Mercedes case discussed in this article illustrates the rough and uncertain nature of this transition. From the perspective of the traditional strategy, the price of the jobs initially promised by Mercedes seemed high; and the ultimate cost was increased by the intense competition among the bidding states. Yet from another perspective, the incentives offered by Alabama can be viewed as “table stakes” for the new global game of economic development.     

Effect of murine retroviral infection on hair and serum levels of cocaine and morphine.

LP-BM5 retrovirally infected female C57BL/6J mice were administered cocaine, morphine or both by daily intraperitoneal injection for 9 weeks. Drug concentrations were measured by radioimmunoassay in serum and in hair extracts. Hair samples obtained from all drug-treated mice were positive for the drug injected, while none of the saline-treated mice had detectable drug levels in hair or serum. The average morphine concentration obtained from non-infected mice was 11 ng/mg hair whereas the amount found in the LP-BM5-infected mice was significantly higher (20 ng/mg hair). Mice injected with both morphine and cocaine were given 50% of the regular dose of each drug and drug levels in the hair of these animals were approximately half that of mice injected with the full dose of the single drug. Non-infected mice treated with both drugs had a mean value of 7 ng morphine/mg hair and 374 ng cocaine/mg hair while retrovirus-infected mice had significantly higher concentrations, 10 ng morphine/mg hair and 1160 ng cocaine/mg hair (P less than 0.001). Serum concentrations of cocaine and morphine were significantly higher (P less than 0.01) in the retrovirus-infected animals from 40 min to 1.5 h. The increased concentrations of cocaine and morphine in serum during retrovirus infection are accompanied by a significant increase in the amount of drug incorporated into the hair matrix. This change indicates that retroviral infection may influence the disposition of these drugs in the systemic circulation.
