A Different Look at Lenin's Legacy: Trust, Risk, Fairness and Cooperativeness in the Two Germanies

What are the long-term effects of Communism on economically relevant notions such as social trust? To answer this question, we use the reunification of Germany as a natural experiment and study the post-reunification trajectory of convergence with regard to individuals' trust and risk, as well as perceived fairness and cooperativeness. Our hypotheses are derived from a model of German reunification that incorporates individual responses both to incentives and to values inherited from earlier generations as recently suggested in the literature. Using data from the German Socio-Economic Panel, we find that despite twenty years of reunification East Germans are still characterized by a persistent level of social distrust. In comparison to West Germans, they are also less inclined to see others as fair or helpful. Implied trajectories can be interpreted as evidence for the passing of cultural traits across generations and for cooperation being sustained by values rather than by reputation. Moreover, East Germans are found to be more risk loving than West Germans. In contrast to trust and fairness, full convergence in risk attitude is reached in recent years

From pattern classification to stratification: towards conceptualizing the heterogeneity of Autism Spectrum Disorder

Pattern classification and stratification approaches have increasingly been used in research on Autism Spectrum Disorder (ASD) over the last ten years with the goal of translation towards clinical applicability. Here, we present an extensive scoping literature review on those two approaches. We screened a total of 635 studies, of which 57 pattern classification and 19 stratification studies were included. We observed large variance across pattern classification studies in terms of predictive performance from about 60% to 98% accuracy, which is among other factors likely linked to sampling bias, different validation procedures across studies, the heterogeneity of ASD and differences in data quality. Stratification studies were less prevalent with only two studies reporting replications and just a few showing external validation. While some identified strata based on cognition and intelligence reappear across studies, biology as a stratification marker is clearly underexplored. In summary, mapping biological differences at the level of the individual with ASD is a major challenge for the field now. Conceptualizing those mappings and individual trajectories that lead to the diagnosis of ASD, will become a major challenge in the near future

Understanding the relationship between cerebellar structure and social abilities.

BACKGROUND: The cerebellum contains more than 50% of all neurons in the brain and is involved in a broad range of cognitive functions, including social communication and social cognition. Inconsistent atypicalities in the cerebellum have been reported in individuals with autism compared to controls suggesting the limits of categorical case control comparisons. Alternatively, investigating how clinical dimensions are related to neuroanatomical features, in line with the Research Domain Criteria approach, might be more relevant. We hypothesized that the volume of the "cognitive" lobules of the cerebellum would be associated with social difficulties. METHODS: We analyzed structural MRI data from a large pediatric and transdiagnostic sample (Healthy Brain Network). We performed cerebellar parcellation with a well-validated automated segmentation pipeline (CERES). We studied how social communication abilities-assessed with the social component of the Social Responsiveness Scale (SRS)-were associated with the cerebellar structure, using linear mixed models and canonical correlation analysis. RESULTS: In 850 children and teenagers (mean age 10.8 ± 3 years; range 5-18 years), we found a significant association between the cerebellum, IQ and social communication performance in our canonical correlation model. LIMITATIONS: Cerebellar parcellation relies on anatomical boundaries, which does not overlap with functional anatomy. The SRS was originally designed to identify social impairments associated with autism spectrum disorders. CONCLUSION: Our results unravel a complex relationship between cerebellar structure, social performance and IQ and provide support for the involvement of the cerebellum in social and cognitive processes

Punishing childhoods: contradictions in children’s rights and global governance

The article considers efforts to eradicate corporal punishment as an aspect of the global governance of childhood and raises problems relevant to global governance more broadly. The article analyses contradictions in children’s rights advocacy between its universal human rights norms and implicit relativist development model. Children’s rights research is influenced by social constructivist theories, which highlight the history of childhood and childhood norms. Earlier social constructivist studies identified the concept of childhood underpinning the Convention on the Rights of the Child (CRC) as a Western construction based on Western historical experiences, which excluded the experiences of childhood in developing countries. More recent social constructivist approaches emphasise how childhood norms are constructed and therefore can be reconstructed. The article outlines problems with attempts to globalise childhood norms without globalising material development. The article discusses the softening of discipline norms in Western societies historically. It indicates problems with children’s rights advocacy seeking to eradicate the corporal punishment of children globally without globalising the material conditions, which underpin the post-industrial ideal of childhood embodied in the CRC

Cerebellar parcellation in schizophrenia and bipolar disorder

International audienceObjective: The cerebellum is involved in cognitive processing and emotion control. Cerebellar alterations could explain symptoms of schizophrenia spectrum disorder (SZ) and bipolar disorder (BD). In addition, literature suggests that lithium might influence cerebellar anatomy. Our aim was to study cerebellar anatomy in SZ and BD, and investigate the effect of lithium.Methods: Participants from 7 centers worldwide underwent a 3T MRI. We included 182 patients with SZ, 144 patients with BD, and 322 controls. We automatically segmented the cerebellum using the CERES pipeline. All outputs were visually inspected.Results: Patients with SZ showed a smaller global cerebellar gray matter volume compared to controls, with most of the changes located to the cognitive part of the cerebellum (Crus II and lobule VIIb). This decrease was present in the subgroup of patients with recent-onset SZ. We did not find any alterations in the cerebellum in patients with BD. However, patients medicated with lithium had a larger size of the anterior cerebellum, compared to patients not treated with lithium.Conclusion: Our multicenter study supports a distinct pattern of cerebellar alterations in SZ and BD
