Risk-taking behaviour and criminal offending: an investigation of sensation seeking and the Eysenck personality questionnaire

This study investigated relationships between hostility, Zuckerman's sensation seeking, and Eysenck and Eysenck's personality scales within a prison population, to explore whether they could be conceptualized in terms of two socialized and unsocialized sensation seeking factors. Participants included 79 incarcerated adult male offenders (age range = 18-62). Findings support the distinction between socialized and unsocialized sensation seeking and suggest that these factors represent more overarching personality factors. Psychoticism was a clear marker of the more broad impulsive, unsocialized sensation seeking factor, rather than representing a supertrait in its own right. This factor was also represented by lie, disinhibition, and boredom susceptibility scales. Findings relating to hostility also supported such a reformulation, as unsocialized scales did cluster together to predict the unsocialized hostility factor, whereas unsocialized scales did not. The results demonstrate the need for a theoretical reformulation of the two given theories of personality.     

Threats and assaults against psychiatrists

In this article, the authors review the literature on surveys pertaining to threats and assaults on psychiatrists and report the results of a questionnaire sent to Oregon psychiatrists. Although the responding psychiatrists were experienced clinicians, they appear to have had relatively little life experience with aggression. Assaults and threats were frequent in their careers, occurred across a variety of clinical settings, and involved a wide range of patients. The authors discuss specific strategies for psychiatrists to minimize the effects of patient threats and assaults and suggest ways in which organized psychiatry can help with the danger and sequelae of patient violence.     

Use of Embryos Extracted from Individual Cannabis sativa Seeds for Genetic Studies and Forensic Applications

Legal limits on the psychoactive tetrahydrocannabinol (THC) content in Cannabis sativa plants have complicated genetic and forensic studies in this species. However, Cannabis seeds present very low THC levels. We developed a method for embryo extraction from seeds and an improved protocol for DNA extraction and tested this method in four hemp and six marijuana varieties. This embryo extraction method enabled the recovery of diploid embryos from individual seeds. An improved DNA extraction protocol (CTAB3) was used to obtain DNA from individual embryos at a concentration and quality similar to DNA extracted from leaves. DNA extracted from embryos was used for SSR molecular characterization in individuals from the 10 varieties. A unique molecular profile for each individual was obtained, and a clear differentiation between hemp and marijuana varieties was observed. The combined embryo extraction–DNA extraction methodology and the new highly polymorphic SSR markers facilitate genetic and forensic studies in Cannabis.     

External Democratization after War: Success and Failure

In post-war societies external actors promote democracy within a broad framework of state- and nation-building, rule-of-law building, and economic development. But not all democracy promotion efforts succeed in an equal way. A closer look at cases of intervention and democratization since 1945 helps us to account for this variation. Cases of democratization can be differentiated according to their level of post-war socio-economic development, the level of social trust versus the level of inner-societal violence, the character of remaining stateness, the potential erosion of the nation, and the terms of peace. In order to explain the democratization successes of the post-World War II period on the one hand, and the apparent democratization failures of the 1990s and after 11 September 2001 on the other, the strategies external actors use in post-war transformation must be considered. Sometimes, external actors differ significantly in their ability and willingness to deal with the five issues mentioned above. Given differences in both structural conditions and actor engagement, external actors should be more careful when using some of the early democratization cases as blueprints for democracy promotion today.     

Integrated DNA and Fingerprint Analyses in the Identification of 60‐Year‐Old Mummified Human Remains Discovered in an Alaskan Glacier

Abstract: This report describes the identification of a merchant mariner who perished in 1948 when Northwest Airlines Flight 4422, a DC‐4 carrying 24 seamen and six crew members crashed into Mount Sanford, Alaska. Fifty‐one years later, a human forearm and hand were found close by the wreckage of the plane, prompting identification efforts using DNA and fingerprints. There were significant challenges to both the fingerprint and DNA analyses. The hand was badly desiccated, making fingerprint friction‐ridge detail almost invisible and the remains had been embalmed upon discovery, making DNA amplification difficult. We present the results of an interdisciplinary approach that successfully addressed these challenges and ultimately led to the identification of the remains. These efforts relied on efficient fingerprint rejuvenation and imaging techniques that improved print resolution, as well as new DNA extraction techniques optimized for aggressively embalmed remains.
