When the strong punish: why net costs of punishment are often negligible

In small-scale societies, punishment of adults is infrequent and employed when the anticipated cost-to-benefit ratio is low, such as when punishment is collectively justified and administered. In addition, benefits may exceed costs when punishers have relatively greater physical and social capital and gain more from cooperation. We provide examples from the Tsimane horticulturalists of Bolivia to support our claims.     

The Labor Market Performance of Naturalized Immigrants in Switzerland—New Findings from the Swiss Labor Force Survey

The objective of this paper is to obtain new empirical insights into the integration of naturalized immigrants in Switzerland. In particular, we focus on a comparison of first-generation immigrants with and without Swiss citizenship. The analysis on the basis of the 2008 wave of the Swiss Labor Force Survey is motivated by findings in the literature highlighting the role of the acquisition of citizenship in the integration process. In line with those findings, our results demonstrate that naturalized first-generation immigrants tend to have higher wages than non-naturalized immigrants. An applied Blinder?COaxaca decomposition technique demonstrates that this result is strongly connected to the higher human capital endowments of immigrants who have attained Swiss citizenship. The findings are in line with other case studies stating that immigrants positively select into citizenship.     

Entwicklungsbezogene Pr?vention von Gewalt und Kriminalit?t

This article provides an overview of concepts and empirical evaluations of developmental prevention of delinquency, violence and other forms of antisocial behavior in childhood and youth. At first basic terms and arguments are discussed; then a selection of family, child school and community-oriented programs are briefly presented. There follows an integrative evaluation of the field that is mainly based on systematic reviews and meta-analyses. An integrative model shows that preventive effects depend on many characteristics of the programs, contexts, participants and evaluation methods. In total effect sizes are positive and small but show practical relevance. There is a strong need for more well controlled outcome evaluations with long-term follow-up and more process evaluations of implementation and quality assurance. Future research and practice should be integrated within a long-term and cross-departmental prevention policy.     

ADHD and delinquency--a developmental perspective

Attention-deficit/hyperactivity disorder (ADHD) is one of the most prevalent psychiatric disorders of childhood and adolescence. Until now, it has been unclear whether ADHD by itself constitutes a risk factor for later delinquency or does so only in combination with other disruptive symptoms. This article seeks to give a comprehensive account of the literature to shed light on the developmental pathway from childhood ADHD to adult criminality. Comorbid ADHD and conduct disorder (CD) are significantly related to a range of biological and environmental risk factors such as neurocognitive impairment, high parental psychopathology, poor social functioning, and other comorbid mental disorders, particularly substance abuse, that are described in this review. In addition, the results of treatment studies are presented, with a special focus on the results of the Multimodal Treatment Study of Children with ADHD (MTA). Although treatment programs, including medication and psychosocial treatment, can be very effective in improving the functioning of children with ADHD in the social and academic domains in the short term, there is no conclusive evidence that such treatments lower the risk for developing delinquency in adulthood.     

Stottern

Stuttering is a fluency disorder with a point prevalence of approximately 1%. Stuttering begins in childhood and is characterized by frequently occurring breaks in the flow of speaking. These fluency breaks are repetitions of words and syllables, prolongations of sounds and pauses. Many people who stutter show avoidance behaviors, social anxiety, shame and social withdrawal. Empirical studies point to genetic origins of the disorder; however, distinct physical deficits causing stuttering are not yet known. While most children outgrow stuttering before adolescence those who do not typically continue to stutter throughout their life. The severity of stuttering as well as its impact on the quality of life can be reduced by a combination of cognitive-behavioral therapy and speech-language therapy.     

Werkzeugkasten des psychodynamischen Psychosetherapeuten

The authors describe the modification of the classical psychoanalytic treatment technique, which was developed in the past decades to treat people with schizophrenic psychosis. The technique which can be used in modified psychoanalytic as well as other psychodynamic settings, was adjusted to the specific problems which occur in the psychotherapy of patients with schizophrenia. This specific modified psychotherapy deals with a paradigmatic experience in the therapeutic relationship to reduce traumatic fear and to overcome interpersonal and intrapsychic dilemmas. This modification increases the possibility to reconstruct the personal history of the psychosis in a dialogical process together with the patient.     

School bullying as a predictor of violence later in life: A systematic review and meta-analysis of prospective longitudinal studies

This paper presents results from a thorough systematic review on the efficacy of school bullying (perpetration and victimization) in predicting aggression and violence later in life. Results are based on prospective longitudinal studies. Two meta-analyses are presented examining whether: a) school bullying (perpetration and victimization) is a significant predictor of later aggression and violence, and b) whether each effect remains significant after controlling for other major childhood risk factors which were significantly related to both the predictors and the outcomes. Results are based on extensive searches of the literature. Nineteen electronic databases and 63 journals were searched from the inception of each database or journal through the end of March, 2012. Bullying perpetration at school was a significant predictor of violence (Adjusted OR = 2.04; 95% CI: 1.69–2.45) an average of six years later in life. This value of OR means that bullying perpetration increased the risk of later violence by about two-thirds. The summary effect size for bullying victimization versus violence was markedly smaller but still highly significant (Adjusted OR = 1.42; 95% CI: 1.25–1.62). This value of OR means that victimization increased the risk of later violence by about one-third. Analyses are presented of various potential moderators (such as the number of risk factors controlled for and the length of the follow-up period) in an attempt to explain the significant heterogeneity in effect sizes. Sensitivity analyses are performed on both meta-analyses, and they indicate that overall there is no evidence of publication bias. The overall findings favor the existence of a more general long-term underlying antisocial tendency rather than a more specific underlying violent tendency. Implications of our research for policy and practice are highlighted and future needs in this area of research are indicated.     

Action production influences 12-month-old infants' attention to others' actions

Recent work implicates a link between action control systems and action understanding. In this study, we investigated the role of the motor system in the development of visual anticipation of others' actions. Twelve-month-olds engaged in behavioral and observation tasks. Containment activity, infants' spontaneous engagement in producing containment actions; and gaze latency, how quickly they shifted gaze to the goal object of another's containment actions, were measured. Findings revealed a positive relationship: infants who received the behavior task first evidenced a strong correlation between their own actions and their subsequent gaze latency of another's actions. Learning over the course of trials was not evident. These findings demonstrate a direct influence of the motor system on online visual attention to others' actions early in development.
