Apparent higher brain weight in suicide victims: possible reasons

In 2000 we tested previously reported findings by Salib and Tadros that brain weight of fatal self-harm victims is higher than of those who died of natural causes. Our results were based on data from 15 suicides and 15 deaths of other causes. Data included matching variables of age, sex, time between death and postmortem examination, and temperature of the surrounding environment. The exploratory variables were brain weight and method of death. No significant difference was found between the brain weights of suicides and others. On the other hand, some differences were obtained for different suicide methods, which also differed in the temperature of the environment, this being lower for the group of suicides that occurred outdoors (around or below 0 degrees C). Once we excluded all the outdoor cases and controls, a significantly higher brain weight was obtained for suicide cases. These and previous results are intriguing and require explanation. Respirator brain syndrome as described by Moseley, Molinari, and Walker in 1976 may provide only a partial explanation. Another possible suggestion is that higher brain weight in suicide victims may be related to previously demonstrated increased amygdala blood flow and subsequent amygdala enlargement due to the increased processing of emotional information.     

Schemaorientierte Psychotherapie mit forensischen Patienten

A total of 19 forensic patients with the diagnosis of a personality disorder participated in a schema-oriented psychotherapy (SOPT) over a period of approximately 2 years. Treatment was carried out in three groups which were separated according to diagnoses from clusters B and C of personality disorders in the Diagnostic and Statistical Manual of Mental Disorders text revision (DSM-IV-TR). The control group of 19 forensic patients received treatment as usual and were paralleled for relevant forensic variables. The SOPT was implemented to raise patient awareness for their maladapted schemas and to modify the associated dysfunctional coping strategies. On the basis of differentiated individual case concepts, therapeutic interventions were carried out at cognitive and behavioral levels. Furthermore, activating therapeutic methods were implemented during treatment sessions to actualize maladapted schemas on an emotional level and to enhance awareness. Treatment effects were assessed by standardized self-rating, staff rating and objective measures. The results showed more positive changes for the schema-oriented treatment groups in comparison to the control group. In contrast staff rating for patients in the control group showed a clear deterioration of the clinical features.     

Reciprocity and Discrimination: An Experiment of Hindu‐Muslim Cooperation in Indian Slums

This article shows that indirect positive reciprocity triggered by experiencing short and superficial cooperation with outgroups' individual members reduces discrimination of other members of the same group. The field research combined a lab‐in‐the‐field experiment and a survey conducted in the slums of Mumbai, an Indian city notorious for Hindu‐Muslim violence. After the treatment manipulated expectations of cooperative behavior, ethnically heterogeneous groups produced as much public goods in a public goods game as homogeneous groups. This positive experience radically reduced Hindu subjects' discriminatory attitudes towards the Muslim minority after the experiment. The effect was equally strong among voters of two extremist parties implicated in ethnic riots. The survey compared reciprocity with alternative explanations of why people discriminate against some, but not other ethnic groups. Indirect positive reciprocity and intergroup contact are associated with less, and relative size of the outgroup with more discriminatory attitudes.     

Sexuell übergriffiges und aggressives Verhalten im Kindesalter Einflüsse entwicklungsrelevanter Faktoren

During the last years increasing attention has been paid to young children and adolescents with sexual coercive behaviour. During the year 2007 altogether 232 boys and 30 girls under the age of 14 years were reported to the police because of sexual assaults. In NRW an increasing number of in- and out-patient institutions offers specific and unspecific treatment programs for these children. The major aim of our study, which is supported by the Ministry of Employment, Health and Social Affairs of the state of NRW, is to evaluate the wide range of different treatment programs and to find predictors for successful or difficult treatment outcomes. Furthermore we are interested in differences between children with sexual problem behaviour and children with exclusively aggressive problems. So far 23 institutions take part in our research project and our total sample currently consists of 75 boys between 9 - 15 years. A psychometric test battery is applied at the beginning of individual treatment. Our first results highlight differences in socio-demographic data between children with sexual coercive behaviour and children with exclusively aggressive behaviour problems. Compared to children with exclusively aggressive problem behaviour, children with sexual problem behaviour come more often from incomplete families with no male parent, have experienced more psychological and physical violence and have been more often victims of sexual abuse. Compared to children with exclusively aggressive behaviour problems they score significantly higher on the “Depression / Anxiety” scale of the SPS-J, although average T-scores for both groups are within the normal range. Regarding cognitive functioning there are no significant differences between both groups.     

Rehab Retrospect: Former Prostitutes and the (Re)construction of Deviance

In this study, in-depth qualitative interviews with former street prostitutes currently in an outpatient drug rehabilitation program are utilized to examine the transition out of prostitution and from a deviant to a non-deviant identity. Little extant literature explores the relationships between stigma management and desistance as prostitutes attempt to exit the industry. This research finds that while in rehab, the women activated meanings of their previous drug addiction both as a stigma management technique and as a cognitive process that distances them from the prostitute identity. They conceptually bundled their prostitution identity with that of drug addiction, ultimately reinforcing that they completed the transition out of deviance.     

“The king of France is bald” reconsidered: a case against Yablo

Stephen Yablo has argued for metaontological antirealism: he believes that the sentences claiming or denying the existence of numbers (or other abstract entities or mereological sums) are inapt for truth valuation, because the reference failure of a numerical singular term (or a singular term for an abstract entity or a mereological sum) would not produce a truth value gap in any sentence containing that term. At the same time, Yablo believes that nothing similar applies to singular terms that aim to refer to an entity whose existence or non-existence is a factual matter, e.g. ‘the king of France’: the failure of the presupposition that there is a unique French king makes some sentences with the term ‘the king of France’, in particular “The king of France is bald”, gappy. In this paper I will show that the sentence “The king of France is bald” must be false, and not gappy, according to Yablo’s own criteria and that, furthermore, the presupposition that the term ‘the king of France’ refers presents a fail-safe mechanism in the same way Yablo thinks abstract presuppositions do—this undermines his argument for metaontological antirealism.     

Amygdala functional connectivity is reduced after the cold pressor task

The amygdala forms a crucial link between central pain and stress systems. Previous research indicates that psychological stress affects amygdala activity, but it is less clear how painful stressors influence subsequent amygdala functional connectivity. In the present study, we used pulsed arterial spin labeling (PASL) to investigate differences in healthy male adults’ resting-state amygdala functional connectivity following a cold pressor versus a control task, with the stressor and control conditions being conducted on different days. During the period of peak cortisol response to acute stress (approximately 15–30 min after stressor onset), participants were asked to rest for 6 min with their eyes closed during a PASL scanning sequence. The cold pressor task led to reduced resting-state functional connectivity between the amygdalae and orbitofrontal cortex (OFC) and ventromedial prefrontal cortex, and this occurred irrespective of cortisol release. The stressor also induced greater inverse connectivity between the left amygdala and dorsal anterior cingulate cortex (ACC), a brain region implicated in the down-regulation of amygdala responsivity. Furthermore, the degree of poststressor left amygdala decoupling with the lateral OFC varied according to self-reported pain intensity during the cold pressor task. These findings indicate that the cold pressor task alters amygdala interactions with prefrontal and ACC regions 15–30 min after the stressor, and that these altered functional connectivity patterns are related to pain perception rather than cortisol feedback.     

TAKING IN MORE OF LIFE

This is a story not only about my father's death but also about how it has affected me and life as I see it. I believe that the circumstances in my life following my father's death are connected to each other and have become my greatest lessons that I have learned in life.     

The Finno-Ugrian suicide hypothesis: variation in European suicide rates by latitude and longitude

The marked variation regarding the suicide rate in 34 European countries is well described by regressing the national suicide rate on the capital cities' latitudes and on an interaction term of squared latitude multiplied with longitude. The interaction term explains 40.8% and 29.1% of men's and women's suicide rate, respectively, and latitude explains a further significant increment of 10.9% and 10.6% variance of men's and women's suicide rate, respectively. This regression model quantifies the Finno-Ugrian suicide hypothesis of Kondrichin and of Marusic and Farmer. The European countries highest in suicide rate constitute a contiguous, J-shaped belt, spanning from Finland to Austria. This area maps onto the second principal component identified for European gene distribution, representing ancestral adaptation to cold climates and the Uralic language dispersion. Thus, population differences in genetic risk factors may account for the spatial pattern in European suicide rates.
