A cure for crime: Can mental health treatment diversion reduce crime among youth?

Youth crime is a serious social problem, as is the high proportion of young offenders in the juvenile justice system who have mental disorders. A recent policy innovation applies the theory of therapeutic jurisprudence and diverts youth with mental disorders to treatment in lieu of further court processing. The expansion of mental health diversion programs reflects an increasingly popular view that there is a causal relationship between youth mental disorders and crime. Policymakers who share this view place greater emphasis on rehabilitation and treatment as a way to reduce crime, rather than on stricter punishment. This paper considers the policy issues around youth mental health diversion programs. In addition, it evaluates the effect of a mental health diversion program for youth that was implemented in Texas. The paper finds that mental health diversion can be used effectively to delay or prevent youth recidivism.

Spectroscopic determination of skin viability. A predictor of postmortem interval

We have demonstrated that skin viability decreases at a measurable rate following death in an animal model. The decreased skin viability was measured by fluorescein diacetate and ethidium bromide using fluorescence emission spectroscopy. There is significant decrease of the fluorescence intensity of the fluorescein diacetate assay between the 1-4 h, the 6-24 h, and the >40 h time points postmortem. For times between 6-24 h and >40 h postmortem the ethidium bromide assay showed consistent and significant increases in signal. The fluorescence measurements in this study showed that under the experimental conditions the time of death could be determined for <4, 6-24, and >40 hapotmotrem. The application of these assays in the field will require further study of the environmental factors.     

Expanded School Mental Health: Challenges and Opportunities in an Emerging Field

Reviews the need for and development of expanded school mental health (ESMH) programs, which provide a continuum of mental health promotion and intervention through school–community partnerships. Since ESMH is a relatively new, but increasingly prominent field, countless issues are being addressed in practice and research and in efforts to bridge practice and research. We review particular content and context dimensions of ESMH in need of development including quality assessment and improvement, empirically supported practice, improving assessment and outcome evaluation, involving educators in the work, understanding school environments, and tailoring programs through qualitative research. Summaries of articles that amplify these themes are provided.     

Comparison of gasolines using gas chromatography-mass spectrometry and target ion response

Gas chromatography-mass spectrometry was used to compare gasoline samples obtained from different sources based on the difference in amounts of certain components found in the headspace of gasoline using target response data. Many suspected arson cases involve comparing an ignitable liquid extracted from fire debris to a liquid found in a suspect's possession to determine if they could have had a common source. Various component ratios are proposed for determining if an unevaporated gasoline sample could have originated from the same source as an evaporated gasoline extracted from fire debris. Fifty and 75% evaporated gasoline samples were both found to contain similar ratios of certain components when compared with its unevaporated source gasoline. The results of the comparisons in this study demonstrate that for cases involving gasoline that has been evaporated up to 50% and extracted from pine, it is possible to eliminate comparison samples as originating from the same source. The results of the 75% comparisons suggest it may be possible to apply the same type of comparison to cases involving 75% evaporated gasoline.     

Identification of ascorbic acid and its degradation products in black powder substitutes

Low explosives such as smokeless powder, black powder, and black powder substitutes have been used in illicit pipe bombings throughout the United States. Some of the newer black powder substitutes are formulated with ascorbic acid, which gradually decomposes as the powder ages, making it difficult if not impossible for the forensic chemist to identify it by traditional bulk techniques. A sensitive method for the identification of residual levels of ascorbic acid in black powder substitutes is presented. Powder samples are extracted with a mixture of acetonitrile and bis(trimethylsilyl)acetamide (BSA), which converts carboxylic acid and alcohol functional groups to trimethylsilyl esters and ethers, respectively. Samples are then analyzed by gas chromatography-mass spectrometry (GC-MS). Results have shown that trace amounts of ascorbic acid can be identified at detection limits that are well below those for traditional bulk techniques. Degradation products for ascorbic acid (hydroxylated carboxylic acids, furanones, and lactones) can also be detected.
