A cross-sectional study on expression of anger and factors associated with criminal recidivism in prisoners with prior offences

Objective: The purpose of this study is to determine demographical characteristics leading to crime recidivism and define anger levels and anger expression manners for those who re-commit crime.Method: All the literate inmates in zmit Closed Penitentiary were included in this cross-sectional study. The prisoners were asked to respond to State-Trait Anger Expression Inventory. Their socio-demographic data were collected and a questionnaire was given to them to determine their state of imprisonment, sentence, nature of the crime in which they were involved, their criminal history, their relationship with inmates and prison staff and substance and alcohol use.Results: Of the 438 prisoners, 302 (68.9%) responded to the questionnaires. Crime recidivism among the study cohort was observed to be 37.4%.Mean trait anger, anger out and anger in scores were significantly higher in prisoners with criminal recidivism in comparison with those who did not have prior criminal records. However, mean anger control scores for prisoners with or without criminal recidivism were similar. Unemployment, education level completed at secondary school or below, having committed a crime under the influence of alcohol or narcotics, having been involved in prison fights, having resisted police officers, caused damage in their vicinity when angry and violent crimes were all found to be possible causes of criminal recidivism. Educational level completed at secondary school or below, getting into fights with other prisoners, unemployment and resisting police officers were determined to be the strongest indicators to predict criminal recidivism when all variables were considered according to a logistic regression model.Conclusion: It can be proposed that those who have problems with officials or hostile towards others constitute a risk group for criminal recidivism. If prisoners with criminal recidivism can be helped to identify and control their anger, their risk of committing a new crime can be minimised.     

Social Norms and the Paradox of Elections’ Turnout

People vote although their marginal gain from voting is zero.We contribute to the resolution of this paradox by presentinga model for equilibrium configuration of attitudes regardingthe decision to vote. Each individual is seen as an element ofa social network, within which pairs of individuals expressideas and attitudes, exerting mutual influence. We model therole of such networks in propagating the mutual influenceacross pairs of individuals. We show that it may suffice thata small set of individuals have a strong feeling about showingup to vote to generate a significant turnout in elections.     

Mismatch distribution analysis of Y-STR haplotypes as a tool for the evaluation of identity-by-state proportions and significance of matches—the European picture

We suggest the use of the mismatch distribution methodology as an easy way to estimate the distance between all pairs of haplotypes present in a sample. This approach allows the evaluation of the proportion of pairs of Y-STR haplotypes that are prone to become identical by state (IBS), in one generation, by recurrent mutation, a statistic of major importance in the forensic field. The mismatch approach presents some advantages alternatively to the empirical one, since it is not necessary to have simultaneous information on STRs and SNPs, and it allows the evaluation of IBS also within-haplogroups. The estimation of IBS at an European scale showed that there is a high population substructuring for this parameter, increasing from southern-central European countries towards west and north, in accordance to what was found for Y-biallelic markers. This result seems to imply a more careful use of large databases for matching evaluation, even in the absence of population structure for general Y-STR diversity. Furthermore, mismatch distribution can be used to measure the distance between a particular haplotype and all the haplotypes in a sample. When applied to the most frequent haplotypes in Europe it revealed that the opportunity for IBS is not directly related to the frequency of a haplotype, but highly dependent on the proportion of neighbouring haplotypes—so, that reporting on the haplotype frequency for evaluating the significance of a match can be misleading.     

Human Identification by Oral Prosthesis Analysis with Probability Rates Higher than DNA Analysis

Several techniques are used to perform an appropriate and reliable human identification. Forensic dentistry has achieved great relevance over the past years. The aim of this article is to report the method used for the identification of a male body found in the colliquative stage of putrefaction. The identification of the victim was succeeded confronting the dental findings found in the corpse with the data present on dental records provided by his dentist. The major elements for the identity′s recognition were a metal core and a prosthetic crown that were being fabricated. These elements associated with the dental records were compelling for the elucidation of the case, and a positive body identification was achieved with high levels of probability. In the present case, cadaveric analysis of stomatognathic system structures achieved a probability value higher than DNA identification techniques, emphasizing the importance of forensic dentistry.     

Psychological and behavioral adjustment in female youths with high or low psychopathic traits

The aim of the present study was to analyze the role of psychopathic traits in female juvenile delinquency. Using a sample of 236 young females from the Juvenile Detention Centers of the Portuguese Ministry of Justice and schools in the Lisbon area, a group of female youths with high psychopathic traits (n = 118; M = 15.84 years of age; range = 14–18 years of age) and a group of female youths with low psychopathic traits (n = 118; M = 15.77 years of age; range = 14–18 years of age) were formed based on the Portuguese version of the Antisocial Process Screening Device-Self-report (APSD-SR). The results showed that young females with high psychopathic traits start engaging in criminal activities and come into contact with the justice system earlier in life; exhibit higher levels of behavioral problems, conduct disorder, delinquent behaviors and serious criminality; and demonstrate lower levels of self-esteem and pro-social behavior. The importance of some variables in predicting group membership (high versus low psychopathic traits) was established through a binary logistic regression. Our findings reinforce the importance of the psychopathy construct for the early identification of potentially high-risk female youths and for the assessment of female youths who have already come into contact with the judicial system.
