The effectiveness of interactive journaling in reducing recidivism among substance-dependent jail inmates

The present study sought to evaluate the influence of interactive journaling on criminal recidivism and identify significant predictors of recidivism among a sample of 183 male inmates incarcerated in a local jail facility randomly assigned to either an interactive journaling condition or a control group. All participants met DSM-IV-TR criteria for substance dependence, had their current offense indicate substance involvement, and had a minimum of one previous arrest in the prior 12 months. The recidivism rate (51%), in terms of subsequent bookings within a 12-month period, for the journaling group was significantly lower than the recidivism rate (66%) for the control group, χ(2)(1, 183) = 4.13, p < .05. The three most significant independent predictors of subsequent bookings were severity of posttraumatic stress disorder, group assignment (journaling vs. placebo), and employment status. Interactive journaling appears to show promise as a brief treatment intervention strategy for substance dependence in local jail settings and may have the potential for reducing recidivism.     

Characterisation of gunshot residue from three ammunition types using suppressed anion exchange chromatography

Gunshot residue (GSR) is commonly analysed in forensic casework using either scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDX) or gas chromatography-mass spectrometry (GC-MS). Relatively little work has been reported on the post-discharge GSR content of non-metallic inorganic or low molecular weight organic anions to distinguish between different ammunition types. The development of an analytical method using suppressed micro-bore anion exchange chromatography (IC) is presented for the analysis of GSR. A hydroxide gradient was optimised for the separation of 19 forensically relevant organic and inorganic anions in <23min and sensitivities of the order of 0.12-3.52ng of anion detected for all species were achieved. Along with an optimised extraction procedure, this method was applied to the analysis of post-ignition residues from three selected ammunition types. By profiling and comparing the anionic content in each ammunition residue, the possibility to distinguish between each type using their anionic profiles and absolute weight is presented. The potential for interference is also discussed with respect to sample types which are typically problematic in the analysis of GSR using SEM-EDX and GC-MS. To the best of our knowledge this represents the first study on the analysis of inorganic anions in GSR using suppressed ion chromatography.     

Detection of Denatonium Benzoate (Bitrex) Remnants in Noncommercial Alcoholic Beverages by Raman Spectroscopy

Illegal alcoholic beverages are often introduced into market using cheap technical alcohol, which is contaminated by denatonium benzoate (Bitrex) of very small concentration. Bitrex is the most bitter chemical compound and has to be removed before alcohol consumption. The home‐made methods utilize sodium hypochlorite to disintegrate particles of denatonium benzoate in alcohol and to remove bitter taste before trading. In this experimental studies, we propose a novel method that detects in a fast way the remnants of denatonium benzoate in dubious alcohol samples by Raman spectroscopy. This method applies a portable Raman spectrometer of excitation wavelength 785 nm and utilizes the effect of surface‐enhanced Raman spectroscopy (SERS) to recognize the suspected alcoholic beverages. High effectiveness (over 98%) of YES/NO classification of the investigated samples was observed when the nonlinear algorithm support vector machine (SVM) was exploited at carefully adjusted detection parameters. The method can identify illicit alcohol within minutes.     

IMAGINING THE LAW: COMMON LAW AND THE FOUNDATIONS OF THE AMERICAN LEGAL SYSTEM

Now Doniger paced, using Kramer as an audience of one, "We are all ruled by the past, although no on understands it. No one recognizes the power of the past" he said, with a sweep of his hand.
"But if you think about it, the past has always been more important than the present. The present is like a coral island that sticks above the water, but is built upon millions of dead corals under the surface, that no one sees. In the same way, our everyday world is built upon millions and millions of events and decisions that occurred in the past. And what we add in the present is trivial.     

The World Wide Web and the U.S. Political News Market

We propose a framework for understanding how the Internet has affected the U.S. political news market. The framework is driven by the lower cost of production for online news and consumers' tendency to seek out media that conform to their own beliefs. The framework predicts that consumers of Internet news sources should hold more extreme political views and be interested in more diverse political issues than those who solely consume mainstream television news. We test these predictions using two large datasets with questions about news exposure and political views. Generally speaking, we find that consumers of generally left‐of‐center (right‐of‐center) cable news sources who combine their cable news viewing with online sources are more liberal (conservative) than those who do not. We also find that those who use online news content are more likely than those who consume only television news content to be interested in niche political issues.     

The dynamics of candidate evaluations and vote choice in 2008: looking to the past or future?

In this paper, we leverage a 10-wave election panel to examine the relative and dynamic effects of voter evaluations of Bush, Palin, Biden, McCain, and Obama in the 2008 presidential election. We show that the effects of these political figures on vote choice evolves through the campaign, with the predictive effects of President Bush declining after the nominees are known, and the effects of the candidates (and Palin), increasing towards Election Day. In evaluating the relative effects of these political figures on individual-level changes in vote choice during the fall campaign, we also find that evaluations of the candidates and Sarah Palin dwarf that of President Bush. Our results suggest a Bayesian model of voter decision making in which retrospective evaluations of the previous administration might provide a starting point for assessing the candidates, but prospective evaluations based on information learned during the campaign helps voters to update their candidate preference. Finally, we estimate the “Palin effect,” based on individual-level changes in favorability towards the vice-presidential nominee, and conclude that her campaign performance cost McCain just under 2% of the final vote share.     

Hierarchical,Three‐Dimensional Measurement System for Crime Scene Scanning

We present a new generation of three‐dimensional (3D) measuring systems, developed for the process of crime scene documentation. This measuring system facilitates the preparation of more insightful, complete, and objective documentation for crime scenes. Our system reflects the actual requirements for hierarchical documentation, and it consists of three independent 3D scanners: a laser scanner for overall measurements, a situational structured light scanner for more minute measurements, and a detailed structured light scanner for the most detailed parts of tscene. Each scanner has its own spatial resolution, of 2.0, 0.3, and 0.05 mm, respectively. The results of interviews we have conducted with technicians indicate that our developed 3D measuring system has significant potential to become a useful tool for forensic technicians. To ensure the maximum compatibility of our measuring system with the standards that regulate the documentation process, we have also performed a metrological validation and designated the maximum permissible length measurement error E_MPE for each structured light scanner. In this study, we present additional results regarding documentation processes conducted during crime scene inspections and a training session.
