Bullying behaviour and criminality: a population-based follow-up study of adolescent psychiatric inpatients in Northern Finland

The recent school shootings in Europe and the USA have raised the question of whether victims of bullying run an increased risk of committing violent crimes later in life, but scientific research in this area is scarce. The aim of this work was to investigate whether bullying behaviour is associated with later criminal offences committed in adolescence and young adulthood. We studied a sample of 508 Finnish adolescents (age 12-17 years) admitted to psychiatric inpatient care between April 2001 and March 2006. Data on crimes committed and the age of onset of criminal activity were extracted from the official criminal records of the national Legal Register Centre in October 2008. The Schedule for Affective Disorder and Schizophrenia for School-Age Children, Present and Lifetime (K-SADS-PL) was used to define bullying status, and to obtain DSM-IV-based psychiatric diagnoses for the adolescents. Violent crimes were statistically significantly associated with bullying behaviour, but not non-violent crimes. Furthermore, being a bully was predictive of an early onset of severe violent offences. When controlled for the psychiatric diagnoses of the adolescents, we observed decreased likelihood of criminality among victims. Thus bullying others may increase the risk of violent offences, while being a victim is not a risk factor for criminality.     

Analysis of ancient human DNA and primer contamination: one step backward one step forward

The analysis of DNA from archaeological human remains is plagued by a unique set of methodological problems concerning contamination with modern exogenous DNA. Through an original approach, we propose complementary methods to identify all potential sources of contamination and complete guidelines for the validation of ancient human sequences. The study presented was conducted on non-European human samples (Polynesian and Amerindian) which were collected with all precautions during excavation. This permitted us to distinguish without ambiguity authentic and contaminant sequences. The samples' origins and histories were perfectly known, allowing us to trace all potential contamination sources and to determine the efficiency of precautions followed during all steps of the study. The data obtained confirm that precautions taken during sampling effectively prevent contamination. However, we demonstrate that human contamination can also be introduced during genetic analyses even if all precautions are strictly followed. Indeed, numerous human contaminations were detected in template-PCR products and negative controls, resulting in a striking diversity of contaminant mitochondrial DNA sequences. We argue that this contamination partly derives from the primers. To our knowledge, no previous experiment has been performed to investigate primers as a possible source of human contamination despite the fact that this specific type of contamination poses a real problem in terms of validating ancient human DNA studies. Finally, we confirm that the detection of contaminants in negative controls is clearly related to the number of PCR cycles used. This study enhances our understanding of contamination processes and confirms that, in reality, an absolutely contamination-free situation cannot be obtained. As a consequence, we propose improvements to the guidelines usually followed in the field in order to take the highly probable contamination of PCR reagents, including primers, into account.     

The Goods Transport Network’s Vulnerability to Crime: Opportunities and Control Weaknesses

This paper presents the findings of a qualitative study into the goods transport sector and its vulnerability to crime. Based on 33 interviews with professionals and law enforcement agents, four interviews with convicted criminals, 26 case files from the Belgian Federal Police and the customs services and 9 informal conversations with law enforcement agency personnel, academics and professionals, the paper analyses what structures, mechanisms, conditions and interdependencies make the goods transport network susceptible to criminal activity. It is suggested that vulnerability to crime is twofold, consisting of opportunities based on weak sector conditions and weak regulation. It will be demonstrated that small and medium enterprises present particular opportunities for criminal exploitation due to their weaker financial position and the lack of crime prevention measures in place. The study found no criminal ‘front’ structures that are transport businesses alone, because of the high start-up costs within the industry; rather, non-transport companies are exploited to connect to the legal transport sector. Finally, the paper identifies key weaknesses in the sector, asking whether there should be due diligence or regulatory duties for certain roles in the supply chain like shipping agents.     

From Armed Neutrality to External Dependence: Swiss Security in the 21st Century

Abstract: Historically, Swiss identity was founded on beliefs in federalism, direct democracy and armed neutrality. Given continued popular support for autonomous self‐defense in an era of transnational threats, it is worth examining whether a small economically interdependent state, such as Switzerland, is single‐handedly capable of providing for its own security. To preview our conclusions, every facet of Switzerland’s security, whether against military threats, terrorism or natural disasters, today benefits from substantial international inputs. At base, Switzerland’s increasing security dependence has been driven by the following dynamics: 1) the general development of institutionalized international cooperation; 2) the evolving nature of the threats Switzerland faces; and 3) political efforts to “securitize” issues not hitherto considered as security problems. Because Swiss security dependence owes more to broad structural factors than deliberate choices, policymakers would be better off embracing this reality by proactively using international organizations to address transnational challenges.     

Predicting discharge in forensic psychiatry: the legal and psychosocial factors associated with long and short stays in forensic psychiatric hospitals

In Germany, both the number of patients treated in forensic psychiatric hospitals and the average inpatient treatment period have been increasing for over thirty years. Biographical and clinical factors, e.g., the number of prior offences, type of offence, and psychiatric diagnosis, count among the factors that influence the treatment duration and the likelihood of discharge. The aims of the current study were threefold: (1) to provide an estimate of the German forensic psychiatric patient population with a low likelihood of discharge, (2) to replicate a set of personal variables that predict a relatively high, as opposed to a low, likelihood of discharge from forensic psychiatric hospitals, and (3) to describe a group of other factors that are likely to add to the existing body of knowledge. Based on a sample of 899 patients, we applied a battery of primarily biographical and other personal variables to two subgroups of patients. The first subgroup of patients had been treated in a forensic psychiatric hospital according to section 63 of the German legal code for at least ten years (long-stay patients, n=137), whereas the second subgroup had been released after a maximum treatment period of four years (short-stay patients, n=67). The resulting logistic regression model had a high goodness of fit, with more than 85% of the patients correctly classified into the groups. In accordance with earlier studies, we found a series of personal variables, including age at first admission and type of offence, to be predictive of a short or long-stay. Other findings, such as the high number of immigrants among the short-stay patients and the significance of a patient's work time before admission to a forensic psychiatric hospital, are more clearly represented than has been observed in previous research.     

Analysis with the Combur-Test--special aspects in forensic trace examination

The Combur Test is a ready-made and easy-to-use pretest for blood. It is based on the oxidation of tetramethylbenzidine (TMB), which is catalysed by haemoglobin and its derivatives. Despite its high sensitivity, there are many known substances which are responsible for false positive and false negative test results. On the basis of experiments of our own, case reports and the pertinent literature special aspects of the application of the Combur Test in the forensic routine case work are discussed.     

A study on the depression levels of children who are brought to the forensic DNA laboratory for paternity testing

This study aims to identify the depression levels of children who were brought to the forensic DNA laboratory for paternity testing. A total of 35 such children were enrolled in the study. Data were gathered using the parent interview form, general information form for children, and the "Child Depression Scale" as it had been tested for validity and reliability in the 6-17 year age group in the country. Data were analyzed using one-way analysis of variance and Scheffe test. The results showed that the age of children who were brought in for paternity testing created a meaningful difference in their depression scores (p < 0.01) while gender did not. In addition, c. 63% of the children in this study did not know why they were in the laboratory, which also caused a meaningful difference in depression scores (p < 0.01).     

Triggers for alcohol‐related violence in young male offenders

Purpose. Improving the effectiveness of offender treatment programmes is important and one approach is to attend to their content. The aim here was to identify triggers to alcohol‐related violence to inform the development of programmes to treat this problem. Method. Information from 149 young male offenders’ accounts of incidents of alcohol‐related violence was studied using thematic analysis. Results. Sixteen triggers for violence were identified and these were organized into six themes: (1) being offended by someone, (2) seeing an opportunity for material gain, (3) seeing others in need of help, (4) perception of threat, (5) distress, and (6) wanting a fight. Discussion. The implications of the results for developing treatments for alcohol‐related violence are presented. First, identifying triggers should be part of the treatment programme and ways of avoiding triggers should be addressed. Second, changing values, specifically hypermasculine and antisocial values, could attenuate the rewards signalled by the triggers. Third, methods of reducing the potency of triggers would be of value and would include addressing issues of need for respect and responses to perceived disrespect. Fourth, non‐violent ways of helping people who are in trouble need to be introduced. Fifth, coping with threat cues through distraction and increasing self‐awareness would reduce the effects of ‘alcohol myopia’. Sixth, seeking fights for excitement could be reduced by examining the costs through motivational procedures. Finally, and self‐evidently, a primary target of treatment programmes to reduce alcohol‐related violence should be to reduce the level and frequency of alcohol intoxication.
