Associations Between Shyness and Internalizing Behaviors,Externalizing Behaviors,and Relationships during Emerging Adulthood

Many studies have documented the ways in which shyness can be a barrier to personal well-being and social adjustment throughout childhood and adolescence; however, less is known regarding shyness in emerging adulthood. Shyness as experienced during emerging adulthood may continue to be a risk factor for successful development. The purpose of this study was to compare shy emerging adults with their non-shy peers in (a) internalizing behaviors, (b) externalizing behaviors, and (c) close relationships. Participants included 813 undergraduate students (500 women, 313 men) from a number of locations across the United States. Results showed that relatively shy emerging adults, both men and women, had more internalizing problems (e.g., anxious, depressed, low self-perceptions in multiple domains), engaged in fewer externalizing behaviors (e.g., less frequent drinking), and experienced poorer relationship quality with parents, best friends, and romantic partners than did their non-shy peers.

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.     

Use of subpopulation data in Australian forensic DNA casework

DNA profiling evidence presented in court should be accompanied by a reliable estimate of its evidential weight. In calculating such statistics, allele frequencies from commonly employed autosomal microsatellite loci are required. These allele frequencies should be collected at a level that appropriately represents the genetic diversity that exists in the population. Typically this occurs at broadly defined bio-geographic categories, such as Caucasian or Asian. Datasets are commonly administered at the jurisdictional level. This paper focuses on Australian jurisdictions and assesses whether this current practice is appropriate for Aboriginal Australian and Caucasian populations alike. In keeping with other studies we observe negligible differences between Caucasian populations within Australia when segregated geographically. However segregation of Aboriginal Australian population data along contemporary State and Territory lines appears to mask the diversity that exists within this subpopulation. For this reason datasets collated along more traditional lines may be more appropriate, particularly to distinguish the most genetically differentiated populations residing in the north of the continent.     

Sensitive and specific quantification of human genomic deoxyribonucleic acid (DNA) in forensic science specimens: casework examples.

We describe the forensic science application of a method for quantification of human genomic deoxyribonucleic acid (DNA). The two cases cited in this report involve DNA samples extracted from skin tissue and bloodstained clothing recovered from different crime scenes. High-molecular-weight DNA was recovered from both specimens, and the concentrations of these DNAs were estimated to be approximately 0.5 microgram/microL by ethidium bromide/agarose gel electrophoresis. Using the human-specific DNA probe p17H8 (locus D17Z1) to quantify the amount of human genomic DNA in these samples, it is shown that less than 1% of the DNA isolated from the skin tissue is of human origin and that the DNA isolated from the bloodstained clothing is effectively devoid of human DNA sequences. These case examples illustrate the need to quantify not only the total amount of DNA recovered from forensic casework material, but also the proportion of the DNA that is of human origin.
