False confessions: The relative importance of psychological,criminological and substance abuse variables

Abstract

The aim of the study was to investigate the relative importance of psychological, criminological, and substance abuse variables in differentiating between alleged false confessors and other prison inmates. The participants were 509 inmates newly admitted to all Icelandic prisons over a four-year period. Sixty-two (12%) of the inmates claimed to have made a false confession to the police sometime in the past. A discriminant function analysis was used to identify the variables that best discriminated between the alleged false confessors and the other prison inmates. Out of 17 psychological variables and 16 criminological and substance abuse variables, two variables (number of previous imprisonments and the score on the Gough Socialisation Scale) correctly classified 93% of the non-false confessors and 32.3% of the alleged false confessors, with a total classification rate of 82.7%. The findings suggest that among Icelandic prison inmates, antisocial personality characteristics and the extent and severity of criminal behaviour, as judged by number of previous imprisonments, are the best predictors of offenders claiming to have made a false confession to the police. The implication is that among some prison inmates, making a false confession is a part of their criminal life style.     

Why negotiate a legally binding mercury convention?

The purpose of this paper is to explain how and why consensus was reached on a legally binding approach given the opposition of powerful actors. Why did the United States and key emerging economies change their positions? We apply tools from the regime formation literature—classical perspectives on power, interests and knowledge—and the use of different leadership tools to shed light on the issue. Knowledge-based intellectual leadership was exercised by the UNEP Secretariat, providing new information on the seriousness and scope of the problem. Power-based leadership through unilateral action was provided by the United States. When the United States changed position after change in domestic leadership, political costs increased for other opponents. Finally, interest-based instrumental leadership was provided by many proponents, with UNEP and among others the EU in the lead. Still, conflicts remain on control measures and the form of financial mechanism.

Assessing the Latent Factor Association Between the Dysphoria Model of PTSD and Positive and Negative Affect in Trauma Victims from India

The recent release of the DSM-5 comes with the division of posttraumatic stress disorder (PTSD) symptoms across four symptom clusters (American Psychiatric Association, 2013). This division is based on the support garnered by two four-factor models; Emotional Numbing (King et al., 1998) and Dysphoria (Simms et al., 2002) and a five-factor model; Dysphoric Arousal (Elhai et al., 2011). Much debate centered on the validity of the Dysphoria factor as a non-specific factor of PTSD within the Dysphoria model. In line with this, we assessed relations between the four factors of the Dysphoria model (Simms et al., 2002) and positive (PA) and negative affect (NA) in natural disaster victims (N?=?200) from Leh, India, using the PTSD checklist (PCL-S) and Positive and Negative Affect Schedule (PANAS short form). Confirmatory factor analysis was implemented to assess the best-fitting model for both the PCL (PTSD) and the PANAS (affect). Two optimal models (the Dysphoria model and a two-factor model for affect) were subsequently used to assess latent variable associations across constructs. It was hypothesized that differential associations between latent factors would be evident with the Dysphoria factor being highly correlated with negative affect compared to alternative PTSD factors. Significant correlations were found between factors of the Dysphoria model and NA (0.52–0.65, p?<?0.001). Comparing the association of pairs of PTSD factors with NA and PA, Wald’s tests revealed that no single PTSD factor was more related to NA than the other. Avoidance and Hyperarousal factors were correlated with PA. Results are discussed in line with literature questioning Dysphoria factor’s unique association with general distress.     

Analysis of active ricin and castor bean proteins in a ricin preparation, castor bean extract, and surface swabs from a public health investigation

In late February 2008, law enforcement officials in Las Vegas, Nevada, discovered in a hotel room, a copy of The Anarchist Cookbook, suspected castor beans and a "white powder" thought to be a preparation of ricin. Ricin is a deadly toxin from the seed of the castor bean plant (Ricinus communis). The United States regulates the possession, use, and transfer of ricin and it is the only substance considered a warfare agent in both the Chemical and the Biological Weapons Conventions. Six samples obtained from the hotel room were analyzed by laboratories at the Centers for Disease Control and Prevention using a panel of biological and mass spectrometric assays. The biological assays (real time-PCR, time resolved fluorescence and cytotoxicity) provided presumptive evidence of active ricin in each of the samples. This initial screen was followed by an in-depth analysis using a novel, state-of-the-art mass spectrometry-based ricin functional assay and high sensitivity tandem mass spectrometry for protein identification. Mass spectrometric analysis positively identified ricin and confirmed that in each of the samples it was enzymatically active. The tandem mass spectrometry analysis used here is the most selective method available to detect ricin toxin. In each sample, ricin was unequivocally identified along with other R. communis plant proteins, including the highly homologous protein RCA120. Although database searches using tandem mass spectra acquired from the samples indicated that additional controlled substances were not present in these samples, the mass spectrometric results did provide extensive detail about the sample contents. To the best of our knowledge following a review of the available literature, this report describes the most detailed analysis of a white powder for a public health or forensic investigation involving ricin.     

Profiling of volatile impurities in tetramethylenedisulfotetramine (TETS) for synthetic-route determination

In recent years, alcohol consumption has been considered an important public health problem. Ethanol, the alcohol used in beverages, is a drug that affects the central nervous system (CNS) and impairs driving skills and co-ordination, increasing risk of deaths and injuries derived from crashes and road accidents. Consumption of alcoholic beverages is implicated with premature deaths, injuries and damages caused by motor vehicle crashes, which result in high costs to government and society. Considering that alcohol consumption is the main responsible factor for deaths and disabilities in young people, the aim of this work was to evaluate the prevalence of blood alcohol in offenders and/or fatal and non-fatal victims of traffic occurrences in the region of Ribeir?o Preto, S?o Paulo State, from 2005 to 2007. The results revealed that in 2134 cases investigated, blood alcohol positivity was generally found in young adults, 25-45 years old and male. The study showed the high risk of drinking and driving and the importance in establishing actions of prevention and intervention to promote the reduction in the number of traffic occurrences related to consumption of alcoholic beverages.     

Regulating the retirement age—Lessons from Nordic pension policy approaches

The likelihood that longevity will continue to increase has generated a search for regulation that make people work longer as they live longer, and thus not just containing pension expenditure but also enlarging labor supply, economic growth, and tax revenue. In public pension policy, Nordic countries have led the world with three types of approaches aimed at making people retire later. The first came when Sweden, followed by Finland and Norway, installed life expectancy coefficients in benefit calculation formulas. The second followed as Finland introduced age-related accrual rates and the third when Denmark indexed the pensionable age to developments in life expectancy. Since economic incentive-based regulations failed to raise exit ages sufficiently, Finland and Sweden subsequently linked pensionable ages to life expectancy like Denmark. While this policy brings out inequalities in health and workability, the fact that countries found it necessary to index the pensionable age to longevity instead of just relying on economic incentives in regulating retirement behavior may hold lessons for other countries.
