Predicting Short-Term Institutional Aggression in Forensic Patients: A Multi-Trait Method for Understanding Subtypes of Aggression

Accurately predicting inpatient aggression is an important endeavor. The current study investigated inpatient aggression over a six-month time period in a sample of 152 male forensic patients. We assessed constructs of psychopathy, anger, and active symptoms of mental illness and tested their ability to predict reactive and instrumental aggression. Across all levels of analyses, anger and active symptoms of mental illness predicted reactive aggression. Traits of psychopathy, which demonstrated no relationship to reactive aggression, were a robust predictor of instrumental aggression. This study (a) reestablishes psychopathy as a clinically useful construct in predicting inpatient instrumental aggression, (b) provides some validation for the reactive/instrumental aggression paradigm in forensic inpatients, and (c) makes recommendations for integrating risk assessment results into treatment interventions.

强国的“支柱”：俄罗斯政党制度的选择

“统一俄罗斯”党奉行“保守主义的现代化”战略,其要旨就在于把自由和公正价值有机统一,构建独立自主的民主制度,使俄罗斯成为现代世界强国。作者以亨廷顿、托克威尔等人的理论为根据,认为任何民主都有自己的特色,多党制并非民主必须的条件,处于现代化进程中的俄罗斯,既不适合实行多党制,也不能实行一党制,而应该实行两党制或一党居优制,这是俄罗斯成为现代世界强国的基础和“支柱”。

Age estimation from the human os coxa: a test on a documented Italian collection*

Current standards for age at death estimation from the pelvis are based on Americans of European and African ancestry. Our limited understanding of population variability hampers our efforts to apply these techniques to the various skeletal populations around the world, especially in global forensic contexts. However, documented skeletal samples are rare, limiting our ability to test our techniques. This study tested the Suchey-Brooks pubic symphysis aging method and the auricular surface method originally developed by Lovejoy et al. on a large sample (n = 404) of known sex and age from the Sassari Collection, housed at the Museum of Anthropology at the University of Bologna, Italy. The results indicate that for both methods, bias and inaccuracy increased with age and actual age tended to be underestimated over the age of 40. The auricular surface method performed slightly better, exhibiting slightly lower levels of bias and inaccuracy, especially for males.     

Unaccompanied refugee children and adolescents: the glaring contrast between a legal and a psychological perspective

Unaccompanied refugee children and adolescents are a vulnerable group: they live not only in a relatively difficult situation as minor refugees staying in another country, but also face other risks due to the absence of their parents, such as traumatic experiences, exploitation or abuse. The difficult living situation of these unaccompanied refugee children and adolescents might therefore threaten their emotional well-being, resulting in important emotional and behavioural problems. This 'psychological' perspective shows the necessity of a strongly elaborated reception and care system for these children and adolescents in order to meet their specific situation and needs. Nevertheless, the case study of unaccompanied refugee minors living in Belgium, as explored in this paper, shows that the legal perspective on these youths - considering them as 'refugees' and 'migrants', not as 'children' - is predominantly the starting point to build the care system on. Moreover, this legal perspective contrasts sharply with the psychological perspective, as such that these children and adolescents do not receive appropriate support and care as they need.     

Judgments of culpability in a filicide scenario

Previous research has indicated that potential jurors are likely to use personal biases, such as those based on gender and ethnicity, in their judgments of culpability of criminal defendants in addition to, or instead of, the facts of the crime. The present paper seeks to extend this literature to the crime of filicide; to examine whether male defendants are judged more harshly than female defendants, as is the case for domestic violence and sexual abuse. 214 participants were provided with a scenario of filicide in which the gender of the perpetrator, the gender of the child, and the family's social class were randomly assigned. Participants were asked to rate the culpability of the defendant in the case. Results indicated that, unlike for other violent crimes, participants did not use gender or social class biases in their judgments of criminal culpability.     

Forensic evaluation of sudden death due to tuberculosis

Abstract:  The emergence of drug-resistant tuberculosis (TB) poses a major threat to TB control efforts. We report a case of a 50-year-old man with pulmonary TB. The scene investigation had initially suspected for homicide; however, the result of medico-legal autopsy demonstrated natural cause of death. Statistical data suggest that the rates of national mortality by respiratory TB decreased in the last decades in Hungary; however, an increasing TB mortality was detected in the capital Budapest. Facing a new mortality trend in TB, the forensic scene investigation and determination of manner of death represent new challenges for practitioners.     

A real-time multiplex SNP melting assay to discriminate individuals

A method that quickly and inexpensively differentiates crime scene samples from multiple donors would expedite casework analysis by allowing the selection of probative items requiring comprehensive testing. This new method need not be perfectly definitive nor give a complete 13 locus short tandem repeat (STR) profile; it simply must be able to differentiate between most victim and suspect samples. We describe the development of multiplex, single nucleotide polymorphism (SNP), fluorescence resonance energy transfer-based real-time polymerase chain reaction (PCR) assays to fulfill this need. Dual probes, one fluorescently labeled and the other labeled with a quencher, are monitored during a melt analysis to reveal an increase in fluorescence, which allows the assessment of the two SNP alleles. Two alternate 6-plex assays (with and without gender determination) have been developed for the six-color RG6000 real-time instrument (Corbett Robotics, Inc.) and one seven SNP plus gender assay (performed as two 4-plex assays, one with gender the other without) have been developed for use in four/five color real-time instruments. This technique can discriminate between 95% and 99% of samples from different individuals. This assay is fast (approximately 2 h), much less expensive than STR analysis, and uses a real-time PCR instrument which is found in most forensic and molecular biology labs.     

Selective colorimetric determination of TNT partitioned between an alkaline solution and a strongly basic Dowex 1-X8 anion exchanger

The Meisenheimer anions formed from TNT in KOH solutions in alcohol or acetone were used in screening tests for TNT among possible nitro-explosives. The same reaction was used for the spectrophotometric assay of TNT in soil by CRREL (Cold Regions Research & Engineering Laboratory of the U.S. Army) method, also known as Jenkins' method, but the color stability was too dependent on the solution composition and the water tolerance was low, necessitating complete drying of soil samples (which may cause partial analyte decomposition) prior to analysis. This study reports the development of a colorimetric method based on the solid phase extraction (SPE) of the Meisenheimer anion formed from TNT and aqueous NaOH into a strongly basic anion exchange resin Dowex 1-X8 (OH(-) form). The orange-red color that developed both in the solid resin and solution phases was persistent for at least 1h. The resin was let to swell in alcohol, washed first with 1M aqueous NaOH, and then with H(2)O before use. To 5 mL of 4-400 ppm TNT solutions in 1:1 (v/v) acetone-water, 0.5 mL of 5% NaOH was added, diluted to 50 mL with 1:1 acetone-water, and the resulting solutions (containing the orange-red Meisenheimer anion of TNT) were agitated at room temperature with 0.9 g resin for < or =50 min. TNT exhibited a reasonably constant distribution coefficient between the resin and aqueous phases. The absorbance of the filtered solutions was measured against a reagent blank at 500nm. The TNT-loaded resins were regenerated with 1M HCl containing sodium sulfite. The calibration line of filtrate absorbance versus analytical concentration was linear over two orders of magnitude between 0.4 and 40 ppm TNT in final solution. Unlike Jenkins' method, the method was tolerant to 100-fold (by mass) of common soil anions like sulfate, nitrate, and chloride. The basic advantages of the developed colorimetric method over the similar CRREL/Jenkins' method may be summarized as color stability, water and common ion tolerance, lowering of the LOD, and widening of the linear range. As opposed to Jenkins' method, the charge-transfer bands characteristic to colorimetric detection were not obscured by the presence of water. The method is suitable for on-site applications, because the color developed in heterogenous solution was stabilized, and the method can be easily practiced with a portable colorimeter to large numbers of samples.
