SNPs in paternity investigation: The simple future

Based on the 52 SNP-plex developed by the SNPforID Consortium, we designed two 10-plex to study single nucleotide polymorphisms (SNPs) for human identification and to establish its usefulness in paternity casework. This 20 autosomal SNP set was studied in 56 paternity investigation cases from South Portuguese resident population, also analyzed with 17 Short Tandem Repeats (STRs). Results obtained with both methodologies were consistent with each other, except for one case where the alleged father could not be excluded by SNPs. No mutation was found in the SNP loci, whereas a mismatch in STRs was detected. The use of SNPs as a complement to the analysis of autosomal STRs in paternity casework can result in paternity index and paternity probability values equivalent or higher than those obtained with more STR loci, but with lower costs. This study shows that instead of using additional STR loci, the analysis of 20 autosomal SNPs, as a complement technique to standard methodologies, is an appealing alternative in paternity investigation cases.     

MtSNP typing before mtDNA sequencing: Why do it?

Analysis of control mitochondrial DNA (mtDNA) hypervariable regions is sometimes the only available method to study hair evidence in forensic casework although being a laborious technique. Nowadays there is a huge interest in new genetic markers such as single nucleotide polymorphisms (SNPs) to type degraded forensic samples. For that purpose, a 10-Plex mitochondrial SNP for haplogroup typing, chosen from several SNP studies and useful to study the most common populations in our laboratory was applied in forensic casework. Hair shafts from three forensic cases with different ethnic backgrounds were studied with mtDNA sequencing and compared with mitochondrial SNPs (mtSNPs) study. Coding mtSNP typing prior to sequencing can allow for a rapid screening in forensic casework, which is emphasized in the first two cases. Moreover, in cases in which mtDNA sequencing fails, mtSNPs can still be detected. This 10 SNP loci multiplex provides a less expensive and simpler method for mitochondrial typing compared to control region mtDNA sequencing, especially when used as a fast screening method.     

Neuropsychological and Criminological Features of Female Homicide Offenders

Few studies have examined life history and cognitive characteristics unique to female homicide offenders. Understanding these characteristics could aid in risk assessment for extreme violence in this group of offenders. The current study utilized t‐tests or chi‐square tests to compare 27 female and 81 male homicide offenders on psychiatric, neurologic, criminal, and cognitive characteristics. Additionally, we explored the role of abuse history in female offenders through Kruskal–Wallis or Fisher's exact tests. Results indicate that in comparison with male counterparts, females are more likely to have history of mood disorder, borderline personality disorder, and abuse. Cognitively, female homicide offenders exhibit circumscribed cognitive impairment in verbal abilities and perform similarly to male homicide offenders across most cognitive tasks. Within the female offender group, history of sexual abuse is associated with higher rates of impulsive homicide and poorer verbal abilities. These findings provide preliminary evidence for distinct factors associated with homicide in women.     

Cyberbullying in Portuguese Schools: Prevalence and Characteristics

This study examined the extent and nature of cyberbullying in 23 Portuguese schools. A sample of 3,525 sixth-, eighth-, and eleventh-grade students completed a self-response questionnaire assessing their perceptions and experiences of cyberbullying. The findings showed that 7.6% of students have been victimized, and 3.9% have bullied others at least once over the last year. The incidences of victimization were higher for females and for the older students. In contrast, more boys reported having bullied others in the eleventh grade. The most frequent medium of cyberbullying was via websites, whilst sending offensive messages was the most widely reported type of behavior. Telling someone about cyberbullying is among the most frequent coping strategies used by cybervictims, who usually chose to tell their friends rather than adults. Implications of these findings for students, schools, and parents are discussed.     

Intimate partner violence against women. Does violence decrease after the entry of the alleged offender into the criminal justice system?

Intimate partner violence(IPV)is simultaneously assumed as a serious crime and a major public health issue,having recurrences as one of its main characteristics and,consequently,re-entries of some alleged offenders in the criminal justice system(CJS).The main goal of this study is to assess if in cases of female victims of IPV,violence decreases after the first entry of the alleged offender in the CJS.A retrospective study was performed based on the analysis of police reports of alleged cases of IPV during a 4-year period.The final sample(n=1488)was divided into two groups according to the number of entries in the CJS(single or multiple)followed by a comparative approach.Results suggest that violence decreases after the first entry of alleged offenders in the CJS.Re-entries were found in only 15.5%of the cases but they were accountable for 3.3 times more crimes on average.Besides,victims of recidivism presented more injuries and required more medical care.Thus,a small group of alleged offenders seems to be more violent and accountable for most of the IPV crimes registered in the CJS suggesting that regardless of legal sanctions aiming to deter violence,these measures may not be enough for a certain group of offenders.This study sustains the need for a predictive model to quantify the risk of repeated IPV cases within the Portuguese population.     

Participatory appraisal in the UK urban health sector

Rapid Rural Appraisal (RRA) and Participatory Rural Appraisal (PRA) emerged in the context of working with rural communities in developing countries. But the principles of participation and of action-oriented research are equally valid for development work in the urban sector, and in industrialised countries. This article describes the use of participatory appraisal techniques in disadvantaged communities in the UK, in the fields of health and social welfare. Drawing on a case-study of her work, the author looks at the practical, organisational, and political difficulties inherent in bringing together multi-agency professionals and public-sector workers, and members of local communities, and in developing a functional consensus between them.     

Attitude to personality disorder among prison officers working in a dangerous and severe personality disorder unit

BACKGROUND: It is well established that staff attitudes to personality disordered patients are commonly negative, characterised by pessimism and rejection. A recent study in forensic psychiatric hospitals has described the psychological and social factors underlying positive attitudes, and suggested that staff with more positive attitudes perform better and are less stressed. AIM: To assess whether it is possible to predict which staff will adjust positively to working with personality disordered people. More specifically to confirm links between attitude to personality disorder and: job performance; perception of managers; personal well-being; burnout; and interaction rates with inmates. METHODS: The opening of a new Dangerous and Severe Personality Disorder unit within a UK prison allowed a longitudinal study of prison officers to be performed, in which a number of measures, including the Attitude to Personality Disorder Questionnaire (APDQ), were collected at three fixed points (at baseline, eight and sixteen months after the opening of the unit). RESULTS: Attitude to Personality Disorder varied over the course of the study, and changes in attitude were linked to events experienced by individual officers. More positive attitude to personality disorder was associated with improved general health and job performance, decreased burnout, and favourable perception of managers. CONCLUSIONS: Attitude to Personality Disorder has important outcomes, and is responsive to the psychosocial environment. Its measurement is not useful for staff selection, because of low stability over lengthy time periods. The APDQ has been demonstrated to be valid measure of attitude to PD, and potentially useful for outcome studies, or benchmarking between units.
