Interviews were conducted with parents of 136 female and 45 male adolescents categorized into risk groups for the later development of an eating disorder. The family and school concomitants of risk status in females were demonstrated to be different from that in males. Risk group female adolescents rated family cohesion, parent-adolescent communication processes, and overall family satisfaction more negatively than the comparison group. Mothers of moderate risk group females reported lower family cohesion than the comparison group; there were no group differences for adolescent females in fathers' ratings of family measures. However, no group differences were found on any of the family measures between male risk and comparison males. For both females and males, there were no significant group differences in family history of eating and mood disorders, or alcohol dependence. Teacher ratings indicated relatively greater internalizing tendencies in the high-risk female group.This investigation was supported by NICHD Grant Number 1R01-HD24700 awarded to Gloria R.

This paper presents an overview of the organisation and the results of the collaborative exercises (CE) of the European DNA Profiling (EDNAP) Group's mitochondrial DNA population database project (EMPOP). The aim of the collaborative exercises was to determine whether uniformity of mtDNA sequencing results could be achieved among different laboratories. These were asked to sequence either the complete mtDNA control region or the two hypervariable regions HVI (16024-16365) and HVII (73-340) from DNA extracts, buccal swabs or bloodstains, proceeding in accordance with the protocol and strategies used in each individual laboratory. The results of the collaborative exercises were employed to identify possible sources of errors that could arise during the analysis and interpretation of mtDNA profiles. These findings were taken as a basis to tentatively make suitable arrangements for the construction of a high quality mtDNA database. One hundred fifty mtDNA profiles were submitted to the evaluating laboratory, and disaccording profiles were classified into four groups corresponding to the source of error: clerical errors, sample mix-ups, contaminations and discrepancies with respect to the mtDNA nomenclature. Overall, 14 disaccording haplotypes (16 individual errors) were observed. The errors included 10 clerical errors, 3 interpretation problems, 2 cases of sample mix-up and 1 case of point heteroplasmic mixture, where the 2 sequencing reactions brought inconsistent base calls. This corresponds to an error rate of 10.7% in a virtual mtDNA database consisting of the collaborative exercise results. However, this estimate is still conservative compared to conclusions drawn by authors of meanwhile numerous publications critically reviewing published mtDNA population databases. Our results and earlier published concerns strongly emphasize the need for appropriate safety regulations when mtDNA profiles are compiled for database purposes in order to accomplish the high standard required for mtDNA databases that are used in the forensic context.  相似文献

It has been a quarter of a century since the first reported decision was handed down with respect to surrogate motherhood by a common law court. Since that initial decision Australian jurisdictions and the United Kingdom have seen a plethora of parliamentary inquiries, legislation and case law. This article reviews these historical legal developments in case law and legislation in both Australia and the UK to identify what, if any, trends are occurring in the regulation of surrogacy. It is suggested from this review that there is a trend towards recognising and allowing altruistic surrogacy. This raises issues of practical and theoretical importance in relation to the definition of family and the regulation of surrogacy.  相似文献

It has often been assumed that a relationship exists between higher levels of cognitive functioning, particularly formal operations, and mature ego functioning in adolescence. This research examined the relationships between ego functioning and two domains of operational thinking: social interpersonal reasoning and physical-mathematical reasoning in 139 high school seniors. Subjects were given two measures of physical-mathematical reasoning, two measures of interpersonal reasoning, and the Sentence Completion Test of ego functioning, as well as a measure of verbal intelligence. Results indicated significant differences between males and females in patterns of correlations as well as in patterns of relationships in a causal analysis. Ego functioning was predicted by interpersonal reasoning for females and by physical-mathematical reasoning and verbal intelligence for males.This research represents a portion of the doctoral dissertation completed by the senior author in 1981.

This article explores the images of ‘girlpower’ and ‘girls as risk-takers’ as important sources for the analysis and management of young women's experiences and behaviours under late modernity. It then focuses on what is known as the grrrlzine culture as a site where these contemporary images of girlhood are challenged and deconstructed. It is argued that grrrlzines create a community for young women within which they can participate in debates about the meaning of girlhood under late modernity. Grrrlzines offer spaces for young women to discuss and organize among themselves, and in particular to wrestle with and parody contemporary images of girlhood. In doing so, they help to complicate and advance feminist youth studies approaches to the role of the public/private split in girls' cultures, places for youth resistance and the ‘problem’ of girls' silence and invisibility in the context of late modernity. The article examines the ways grrrlzines appear to be complicit in the silencing of young women by insisting on expression only within liminal spaces. However, it is suggested that this constitutes an important attempt on the part of some young women to evade new regulatory regimes that operate primarily by inciting them to speak.  相似文献

This study investigated genetic and environmental influences on the associations between mother–child relationship quality (warmth and hostility) and adolescent conduct problems and cigarette use. Participants included 601 mothers and adolescent twin pairs (aged 12–17 years). Mothers and adolescents provided separate reports of mother-to-child warmth and hostility. A combined measure of mother and adolescent reported conduct problems was used while adolescents provided reports of their cigarette use. Analyses were conducted using bivariate genetic analyses of correlated factors models and regression analyses of monozygotic twin differences. Genetic influences were found for most ratings of the parent–child relationship, with evidence of gender and/or rater-specificity for some measures. The relationship between mother–child hostility with adolescent conduct problems and cigarette use was influenced by genetic and environmental effects. Evidence was found for shared environment effects on the relationship between mother–child warmth and conduct problems. Examining monozygotic twin differences provided further support for non-shared environmental influence on the relationship between mothers’ expressions of hostility and low warmth and adolescent adjustment. Findings are discussed in relation to the interplay between genetic and environmental effects underlying links between parent–child relations and adolescent behavior problems.

ABSTRACT

Recent studies show that using Voting Advice Applications (VAAs) affects party preferences of voters, and hence leads to party switching. Party switching is a necessary but insufficient condition for volatility (a net switch of voters to other parties) and fragmentation (more parties gaining seats) at the aggregate level of electoral constituencies. The research question addressed here is whether the availability of VAAs in electoral constituencies weakens or strengthens trends towards greater volatility and fragmentation as observed in western democracies in the last decades. The data come from 380 Dutch municipalities during the 2014 Dutch municipal council elections. In 133 of them a VAA was available. Using a moderated mediation model that controls for the municipal self-selection of a VAA, we find that a VAA by itself leads to higher levels of volatility and fragmentation. However, VAA availability has a dampening effect in municipal constituencies with characteristics (e.g. population size, ethnic diversity, young average age) that would otherwise make them more susceptible and prone to volatility and fragmentation.  相似文献

As mobile phones are rapidly spreading across Sub-Saharan Africa, scholars and development practitioners are becoming increasingly interested in participatory, information and communication technology (ICT)-enabled initiatives to address the challenges of governance in the region. For such efforts to succeed, ICT interventions need to be custom-tailored to the characteristics of the politically marginalised groups they seek to empower. To advance the generation of the necessary empirical data, we surveyed 1498 respondents in Togo. Findings suggest that sociodemographic factors limiting political participation partially overlap with factors that limit access to ICT and the development of digital skills. Based on these findings, we formulate policy recommendations for the design of ICT-enabled projects that proactively seek to increase the participation of marginalised groups.  相似文献
