Risk and protective factors of delinquency that are sensitive to migration and culture

ABSTRACT

Present evidence regarding widely used risk assessment tools suggests that such tools may have inferior predictive validity for offenders with a migration background (MB), especially from Turkey and Arab countries. Based on a thorough literature review, we investigated additional risk and protective factors via a postdictive correlational study design. We assumed that delinquency is induced by discrimination, a conflict of values, norms of honour, a disapproval of sexual self-determination, and antisemitism. In contrast, we expected social support to diminish the risk of criminal behaviour. The sampling took place inside and outside prison, where adult men with an Arab or Turkish MB (n?=?140) filled out a questionnaire. Individual norms of honour (r?=?.27?.41), antisemitism (r?=?.31?.37), and a disapproval of sexual self-determination (r?=?.23?.26) were positively correlated with delinquency. The best predictor was the individual’s perception of friends’ norms of honour (r?=?.34?.56). However, only a few significant correlations were found for a perception of individual discrimination (r?=?.08?.14) and an internal conflict of values (r?=?.11?.15), whereas global discrimination (r?=?.20?.29) clearly emerged as a risk factor for delinquency. Social support by nondelinquent peers could be confirmed as having a protective influence against delinquency (r=?.25?.27). Theoretical and practical implications for risk assessment are discussed.     

What Role for the Party Group Leader? A Latent Variable Approach to Leadership Effects on Party Group Cohesion in the European Parliament

Previous research has identified several structural and situational factors that affect party cohesion in parliamentary voting behaviour. The potential role of leadership has been neglected so far. The authors apply a latent variable approach to model leadership effects in roll call votes from the European Parliament (EP), 1979–2001. Other things being equal, their findings suggest that a small but significant 7 per cent share of the total variance in party group cohesion is due to the party group leaders. About 40 per cent of this leader component can be accounted for by their experience inside the European institutions, their career prospects, and their ideological positions.     

Clinical forensic examination findings and legal outcome in cases of suspected physical child abuse

Clinical forensic examinations performed at the Institute of Legal Medicine of the Hanover Medical School between 1999 and 2008 in cases of suspected physical abuse of children were analyzed retrospectively with special emphasis on the legal consequences. Altogether, 192 children (85 girls, 107 boys) with a median age of 4.4 years were examined. In 47 cases (24.5 %), the clinical forensic examination findings were interpreted as accidental injuries, birth traumas or unspecific findings. 29 victims (20.0 %) had suffered a shaken baby syndrome. Only part of the presented cases ended with conviction, which was more likely if the victims were aged between 7 and 11 years. Prison terms of 2 years and more were imposed only if the child suffered potentially or acute life-threatening injuries or if additional anogenital lesions were diagnosed indicating sexual child abuse.     

Wie entstehen Preise?

How are prices made? From the perspective of economic price theory prices are determined by supply and demand, while from an economic sociology point of view they result from the embeddedness of market transactions in institutions, networks or cultural frames of meaning. In order to build a price, the value of a good has to be transformed into economic value, i.e. a price. The paper analyses the process of transformation from value to price on the market for the rating of structured finance products. On this market, with the help of calculative practices, the abstract value of ??creditworthiness?? is converted into a concrete rating which determines credit costs. As the subprime crisis has shown, the credit bureaus and rating agencies responsible for this translation process have not been able to draw the price near to the value to which it refers. The article describes the divergence between value and price as the ??social space?? where price building is influenced by social factors that may distort prices and lead to a breakdown of the market.     

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.     

Age assessment of ivory by analysis of 14C and 90Sr to determine whether there is an antique on hand

This report describes the histological changes observed in the heart a young methamphetamine abuser who died of heart failure. Most of the microscopic changes in the heart have previously been described in experimental animals, but never clearly illustrated in man. Gross examination of the heart revealed concentric myocardial hypertrophy (heart weight 470 g versus median predicted weight of 312 g). Areas of old myocardial infarction were also evident, along with enzymatic evidence indicating that a new infarct had occurred. Myocardial remodeling was extensive with perivascular and interstitial fibrosis, cellular vacuolization, and ongoing myocyte destruction with proliferation of fibromyocytes in the intestitum. Of note were the widespread, bizarre looking, distorted, cell nuclei. They were reminiscent of those seen in viral-induced dilated congestive cardiomyopathy. Clinical chemical measurements also showed unequivocal evidence of both evolving infarction and profound heart failure, with a BNP > 5000. This pattern has not previously been reported in humans, probably because forensic pathologists rarely examine the hearts of methamphetamine abusers microscopically. If the pattern observed here is typical for methamphetamine-induced cardiotoxicity, it could well explain increasing reports of heart failure in methamphetamine abusers. It might also be diagnostic for the disorder.     

Degradation of biomolecules in artificially and naturally aged teeth: implications for age estimation based on aspartic acid racemization and DNA analysis

Postmortem teeth are the most stable structures, and can be used to gain different information (age estimation, genetic data). Over long postmortem intervals (PMI), degradation processes may alter the molecular integrity and thus affect the reliability of applied molecular methods. Whereas some knowledge on the degradation of biomolecules in bone during the PMI exists, data for teeth are lacking. In particular, the impact of degradation processes in dentine on age estimation based on aspartic acid racemization (AAR) cannot be estimated yet. Hence, the molecular stability of both collagen and DNA was analyzed systematically, and their impact on the reliability of age estimation based on AAR and genetic analyses was checked. Two hundred and ten human and 59 porcine teeth were heated (90 degrees C in water) to simulate collagen and DNA diagenesis; 14 naturally aged teeth (PMI: 3 days to 1700 years) were analyzed comparatively. Peptide patterns of cyanogen bromide (CNBr)-cleaved collagen were employed as a new approach to check the collagen integrity. In the same samples, collagen yields, amino acid compositions, AAR in different protein fractions, and DNA integrity were analyzed. In heated human and porcine teeth the collagen content declined during the heating experiment. The amino acid composition in human samples was collagen-like until 12 days of heating. In naturally aged teeth, the collagen yielded from 9.5 to 15%, and no discrepancy of amino acid composition to that of modern collagen was observed. Electrophoresis of CNBr-peptides showed an altered pattern in experimentally degraded samples from day 10 on; naturally aged collagen displayed the typical collagen pattern. AAR increased in all protein fractions with increasing duration of the heating experiment; naturally aged samples displayed a slow accumulation of AAR. DNA degraded progressively, and after 32 h of heat exposure no more DNA was detectable, whereas the amplification of nuclear and mitochondrial DNA was successful up to 48 h. STR typing was reliable up to 16 h, and sex determination up to 40 h of heat exposure. In naturally aged samples of DNA quality, yield and typing success did not correlate with PMI. The data highlight a remarkable stability of collagen dental proteins. Within relevant forensic periods a postmortem rise of AAR under normal conditions is negligible, and analyses of dental DNA has a high chance to be successful. However, after large PMI and/or extreme postmortem conditions age estimation based on AAR and genetic analyses lose their reliability.
