Initial Risk Matrix, Home Resources, Ability Development and Children's Achievement

This paper investigates the role of self-productivity and home resources in ability formation from infancy to adolescence. In addition, we study the complementarities between basic cognitive, motor and noncognitive abilities and social as well as academic achievement. Our data are taken from the Mannheim Study of Children at Risk (MARS), an epidemiological cohort study following the long-term outcome of early risk factors. Results indicate that initial risk conditions cumulate and that differences in basic abilities increase during development. Self-productivity rises in the developmental process and complementarities are evident. Noncognitive abilities promote cognitive abilities and social achievement. There is remarkable stability in the distribution of the economic and socio-emotional home resources during the early life cycle. This is presumably a major reason for the evolution of inequality in human development.school achievement, social competencies, persistence, intelligence, home resources, initial conditions

Initial Risk Matrix, Home Resources, Ability Development and Children's Achievement

This paper investigates the development of basic cognitive, motor and noncognitive abilities from infancy to adolescence. We analyse the predictive power of these abilities, initial risk conditions and home resources for children's achievement. Our data are taken from the Mannheim Study of Children at Risk (MARS), an epidemiological cohort study, which follows the long-term outcome of early risk factors. Results indicate that differences in abilities increase during childhood, while there is a remarkable stability in the distribution of the economic and socio-emotional home resources during childhood. Initial risk conditions trigger a cumulative effect. Cognitive, motor and noncognitive abilities acquired during preschool age contribute to the prediction of children's achievement at school age. --Initial Conditions,Home Resources,Intelligence,Persistence,Social Competencies,School Achievement

Effects of age at school entry (ASE) on the development of non-cognitive skills : evidence from psychometric data

We identify effects of age at school entry (ASE) on the development of child temperament. Our analysis is based on psychometric measures from a longitudinal cohort study of children in the Rhine-Neckar region in central Germany. In children with a higher ASE due to a birthday late in the year, we find more favorable outcomes with respect to several temperamental dimensions: These children are more persistent and less often hyperactive. The findings are robust if we control for the respective temperamental dimension before entering school. We also show that the ASE effect on persistence is stable over time by comparing the children at age eight and age eleven, after the children have entered Germany’s segregated secondary-school tracks. At age eleven, we additionally find significant ASE effects on adaptability to change. Overall, the results point to a high degree of malleability in the considered non-cognitive skills after school entrance

Mutter-Kind-Interaktion im Säuglingsalter, Familienumgebung und Entwicklung früher kognitiver und nicht-kognitiver Fähigkeiten: Eine prospektive Studie

In der vorliegenden Studie wird anhand von Daten einer prospektiven Längsschnittstudie (Mannheimer Risikokinderstudie) untersucht, welchen Beitrag die Qualität der Mutter-Kind-Interaktion (MKI) im Säuglingsalter zur Vorhersage kognitiver (IQ) und nicht-kognitiver Fähigkeiten (Persistenz) bis zum Vorschulalter leistet. Dazu wird ein ökonometrisches Modell verwendet, das zusätzlich zu den durch Verhaltensbeobachtung gewonnenen MKI-Maßen die psychosoziale und organische Risikobelastung bei Geburt, die sozio-emotionale Familienumgebung und das Haushaltseinkommen enthält. Sowohl Merkmale der Mutter (Feinfühligkeit) als auch Merkmale des Kindes (Reaktivität) tragen bedeutsam zur Prognose des IQ und der Persistenz bei. Der Erklärungswert der Interaktionsvariablen wird durch die anderen Einflussfaktoren nur teilweise eingeschränkt. --Frühe Mutter-Kind-Interaktion,mütterliche Feinfühligkeit,Reaktivität des Kindes,Geburtsrisiken,psychosoziale Risiken,Intelligenzentwicklung,Familienumgebung

Nucleotide Sequence Variation within the PI3K p85 Alpha Gene Associates with Alcohol Risk Drinking Behaviour in Adolescents

While the phosphatidylinositol 3-kinase (PI3K)-dependent signaling pathway is typically known to regulate cell growth and survival, emerging evidence suggest a role for this pathway in regulating the behavioural responses to addictive drugs.To investigate whether PI3K contributes to patterns of risky alcohol drinking in human, we investigated genetic variations in PIK3R1, encoding the 85 kD regulatory subunit of PIK, in 145 family trios consisting of 15-16 year old adolescents and their parents. Screening for mutations in exons, exon-intron boundaries and regulatory sequences, we identified 14 single nucleotide polymorphisms (SNPs) in the PIK3R1 gene region from exon 1 to the beginning of the 3' untranslated region (UTR). These SNPs defined haplotypes for the respective PIK3R1 region. Four haplotype tagging (ht)SNPs (rs706713, rs2302975, rs171649 and rs1043526), discriminating all haplotypes with a frequency >or=4.5% were identified. These htSNPs were used to genotype adolescents from the "Mannheim Study of Risk Children" (MARC). Transmission disequilibrium tests in these adolescents and their parents demonstrated sex-specific association of two SNPs, rs2302975 and rs1043526, with patterns of risky alcohol consumption in male adolescents, including lifetime prevalence of drunkenness (p = 0.0019 and 0.0379, respectively) and elevated maximum amount of drinking (p = 0.0020 and 0.0494, respectively), as a measure for binge drinking pattern.Our findings highlight a previously unknown relevance of PIK3R1 genotypes for alcohol use disorders and might help discriminate individuals at risk for alcoholism

Proposal for Quantum Simulation via All-Optically Generated Tensor Network States

We devise an all-optical scheme for the generation of entangled multimode photonic states encoded in temporal modes of light. The scheme employs a nonlinear down-conversion process in an optical loop to generate one- and higher-dimensional tensor network states of light. We illustrate the principle with the generation of two different classes of entangled tensor network states and report on a variational algorithm to simulate the ground-state physics of many-body systems. We demonstrate that state-of-the-art optical devices are capable of determining the ground-state properties of the spin-1/2 Heisenberg model. Finally, implementations of the scheme are demonstrated to be robust against realistic losses and mode mismatch.Comment: 6 pages main text plus 6 pages Supplementary Material and many figures.
