Performance evaluation of the Scent Transfer Unit (STU-100) for organic compound collection and release

The Scent Transfer Unit (STU-100) is a portable vacuum that uses airflow through a sterile gauze pad to capture a volatiles profile over evidentiary items for subsequent canine presentation to assist law enforcement personnel. This device was evaluated to determine its ability to trap and release organic compounds at ambient temperature under controlled laboratory conditions. Gas chromatography-mass spectrometry (GC-MS) analyses using a five-component volatiles mixture in methanol injected directly into a capture pad indicated that compound release could be detected initially and 3 days after the time of collection. Additionally, 15 compounds of a 39-component toxic organic gaseous mixture (10-1000 parts per billion by volume [p.p.b.(v)]) were trapped, released, and detected in the headspace of a volatiles capture pad after being exposed to this mixture using the STU-100 with analysis via GC-MS. Component release efficiencies at ambient temperature varied with the analyte; however, typical values of c. 10% were obtained. Desorption at elevated temperatures of reported human odor/scent chemicals and colognes trapped by the STU-100 pads was measured and indicated that the STU-100 has a significant trapping efficiency at ambient temperature. Multivariate statistical analysis of subsequent mass spectral patterns was also performed.     

Assessing Legitimate Structures for the Making of Transnational Labour Law: The Durability of Corporatism

In recent years, there has been greater scrutiny of the legitimacyof governance within international and regional institutionsand an emerging interest in deliberative democracy. This paperexamines the potential impact of these trends on the survivalof current mechanisms for the making of transnational labourlaw, which may be thought to reflect corporatist rather thanpluralist or deliberative practices. We focus on two examples:the tripartite constitutional foundation of the InternationalLabour Organisation, which ensures that employer and workerrepresentatives share in standard-setting alongside governmentrepresentatives, and the predominantly bipartite process ofsocial dialogue between management and labour for the formulationof European Community social policy. Despite significant differencesin approach, both organisations have chosen to prioritise participationby trade unions and employer representatives within designatedbargaining structures that are ostensibly designed to achievesome balance in their relative influence; however, the reasonsfor this preference have not always been apparent. This paperinvestigates how corporatist structures have been adapted forapplication at the international and European level, and seeksto analyse their potential for legitimacy, and thereby theirdurability.     

Overview of: “Getting the Law Involved a Quasi-Experiment in Early Intervention Involving Collaboration Between Schools and the District Attorney's Office”

Research Summary Precursors to serious and chronic delinquency often emerge in childhood, stimulating calls for early interventions. Most intervention efforts rely solely on social service programs—often to the exclusion of the juvenile justice system. The juvenile justice system has been reluctant to become involved in the lives of relatively young children fearing net widening or further straining resources that could be used for older youth with documented delinquency histories. We report here the results of an early intervention program sponsored by and housed in a district attorney's office in Louisiana. Using a quasi-experimental design, we examined outcomes associated with program involvement as well as whether the obvious involvement of the prosecutor's office was associated with further reductions in problem behavior.

• 1 : The results revealed that significant reductions in problem behaviors of young children could be attributed to program participation.
• 2 : The obvious involvement of the district attorney's office, however, was associated with limited, albeit significant, reductions in specific problem behaviors.
• 3 : These findings show that successful early intervention efforts can be made part of the juvenile justice system and that in some limited situations prosecutorial involvement can result in positive outcomes.

Policy Implications The expansion of early intervention programming into the juvenile justice system offers opportunities to address early problem behavior. Our study and its results have the following policy implications.

• 1 : Closely coupled partnerships between schools and the juvenile justice system can effectively address, mitigate, and perhaps prevent an early onset of antisocial behavior.
• 2 : Even so, coupling early intervention efforts to the mission of the juvenile justice system warrants debate. Net-widening, resource diffusion, and the potential for officials to rely too heavily on the deterrent characteristics of the justice system represent serious threats to the integrity of effective early intervention programs.
• 3 : We suggest substantial debate and consideration is given before coupling early intervention efforts to the juvenile justice system.

     

Organizational and Human Factors Affecting Forensic Decision-Making: Workplace Stress and Feedback

Although forensic examiners operate in a stressful environment, there is a lack of understanding about workplace stress and feedback. These organizational and human factors can potentially impact forensic science judgments. In this study, 150 practicing forensic examiners from one laboratory were surveyed about their experiences of workplace stress, and the explicit and implicit feedback they receive. Forensic examiners reported that their high stress levels originated more from workplace-related factors (management and/or supervision, backlogs, and the pressure to do many cases) than from personal related factors (family, medical, and/or financial). The findings showed that a few (8%) of the forensic examiners sometimes felt strong implicit feedback about what conclusions were expected from them and that some (14%) also strongly felt that they were more appreciated when they helped to solve a case (e.g., by reaching a “match” as opposed to an “inconclusive” conclusion). Differences were found when comparing workplace stress and feedback levels across three core forensic science fields (forensic biology, chemistry, and latent prints) and across career stages (early, mid, and late). Gaining insights into the stress factors within a workplace and explicit and implicit feedback has implications for developing policies to improve the well-being, motivation, and performance of forensic examiners.     

Position Effect on Facial Soft Tissue Depths: A Sonographic Investigation

The head is positioned erect for an approximation; yet most facial soft tissue depths (FSTD) used are measured from supine subjects. Depth difference might be significant, but there is a paucity of data to verify. This study compared erect and supine values for 17 landmarks from 30 healthy New Zealand (European population affinity) women (18–30 or 40–55 years) in erect then supine positions. Height, weight, and sonographic FSTD data, totaling 1020 measurements, were obtained. Three midline and seven averaged bilateral values were compared using ANOVA, p values, and Pearson's correlations. Correlative strength of age and body mass index, BMI (kg/m²), was determined by values. Results showed averaged erect and supine differences were significant for four of ten FSTDs. Between individuals, difference was various and not unidirectional. In conclusion, depth differences were observed but not all significant or unidirectional, BMI significantly influenced nine FSTD values, but age group did not.     

New Labour in Perspective: A Comment on Rubinstein

In a recent issue of this journal, David Rubinstein (2000) questioned Stephen Driver and Luke Martell's characterisation of New Labour as a fundamental break with the past. Rubinstein notes important continuities between 'Old' Labour governments and the current Blair government, and correctly challenges Driver and Martell's simple 'old'/'new' portrayal. However, he underestimates the extent to which contextual changes impact upon a left-of-centre government's ability to achieve its aims.
