资产构建视域的新加坡公共住房制度考察

大多数人拥有住房所有权是新加坡公共住房制度的主要特征。从整体上看,公共住房制度对资产构建起到了积极作用。对于物质资产和人力资产构建而言,建立在住房所有权基础上的公共住房制度创造了一种提高劳动生产率和经济增长的机制,这最终使人们可能拥有更大面积的住房。对于社会资产构建而言,公共住房制度有助于家属关系、种族关系和社区关系的改善。住房所有权的资产构建性创造了一种推动社会全面发展的机制。     

Correlation of surnames and Y-chromosome in Central-Brazil

In patrilineal societies, surnames and Y-specific haplotypes and haplogroups are expected to be correlated. This characteristic could help defining an initial pool of suspects in forensic genetics analysis. Here we evaluated this correlation in a sample of Central-Brazilian men. Surnames and Y-SNP haplogroup and Y-STR haplotype were analyzed in 55 pairs of Central-Brazilian men sharing surnames (n = 110). Seven haplogroups and thirty-two haplotypes have been observed, none correlated solely to any of the twenty-eight surnames represented here. In this sample, two men with the same surname showed a chance of 0.41 of sharing a Y-specific haplogroup. This chance is higher for surnames of intermediate frequencies, whereas rare surnames show distinct chances as zero and one. Observed results may be over-estimated due to a predominance of a specific haplogroup (P92R7 = 49%) in the sample, what makes it possible for two men with no coancestry to share this haplogroup. Considering STR, only three pairs of men shared haplotypes. The average difference between the haplotypes in each pair was 2.45 mutational steps. This relatively low correlation is due to some historical and cultural peculiarities of the country, what makes it improper for forensic purposes in Brazil.     

Klagebefugnis aus dem allgemeinen Willkürverbot bei einem Verstoß gegen die Staatszielbestimmung Umweltschutz

Zusammenfassung Nach einer Entscheidung des Bayerischen Verfassungsgerichtshofs kann ein Bauleitplan wegen Versto? gegen das Willkürverbot aus Gründen des Umweltschutzes nichtig sein. Diese auf eine Popularklage ergangene Entscheidung er?ffnet die Frage, ob der Verfassungsgrundsatz des Willkürverbots auch im Rahmen von Verwaltungsakten herangezogen werden kann. Der Beitrag bejaht diese M?glichkeit.     

JOINT CUSTODY AND THE PRESCHOOL CHILD

A longitudinal study of 25 families, with children aged 14 months—5 years, in joint custody, is reported. Varying motivations that lead divorcing parents to undertake and sustain joint custody are discussed, together with the stresses and gratifications of these arrangements for the parents and children. Findings are that where both parents are motivated primarily by interest in the child, where the parenting is sensitive and where the child is shielded from interparental conflict, young children do well. Such families were not the majority in this study. Significant differences emerged in the adjustment of the 1–3 age group as compared with the 3–5 age group which point to greater difficulties for the 3–5 year-olds.
