Genetic and environmental influences in adolescent peer socialization: evidence from two genetically sensitive designs

Harris argues that peer relationships are the chief determinants of personality development. Harris's thesis makes the behavioral genetic investigation of peer groups particularly timely. The present study examined genetic and environmental contribution to self-reported peer-group characteristics in two samples of adolescent siblings: 180 adoptive and nonadoptive sibling pairs from the Colorado Adoption Project, and 386 sibling pairs from the Nonshared Environment and Adolescent Development Study. Substantial genetic influence emerged for college orientation, with the remaining variance accounted for by nonshared environment. For delinquency, however, the majority of the variance was explained by nonshared environment. Although genetic influence was implicated for peer popularity in twin analyses, genetic factors were not important in explaining individual differences in nontwin siblings. These results suggest that although some dimensions of peers are somewhat mediated by genetic factors, nonshared environmental influence is substantial.  相似文献   

Deal‐making and rule‐breaking: behind the façade of equity in academia     

Sue‐Ellen Kjeldal  Jennifer Rindfleish  Alison Sheridan 《Gender and education》2005,17(4):431-447

A glass ceiling for women still exists in academia after two decades of equal employment opportunity (EEO) legislation in Australia. There are complex factors that when combined make gender inequity in the higher education sector highly resistant to change. Using personal histories as a reflexive device, the paper makes explicit the embedded male patterns of behaviour in academia that operate beneath the façade of policies and rules put into place to counter inequity. In particular, the paper focuses on the cognitive dissonance individuals experience due to the disparity between formal organizational policies promoting equity, such as workload allocations, and perceptions of the unequal opportunities for women and men. Using social identity theory and the leader member exchange (LMX) framework, the daily experiences of three academic women are interpreted, the impediments to equality identified, and suggestions made for more fundamental change to gendered organizational structures within academia. The analysis of such behaviours shows that the traditional emphasis of EEO legislation on formal policies and procedures to bring about gender equity in academia needs to be accompanied by cultural change programs that make explicit and challenge behaviours that reproduce and reinforce male hegemony in academia.  相似文献   

Using the theory of planned behaviour framework to understand Tasmanian dairy farmer engagement with extension activities to inform future delivery     

Alison Hall  Lydia Turner  Sue Kilpatrick 《The Journal of Agricultural Education and Extension》2019,25(3):195-210

Purpose: To identify and understand factors influencing farmers’ decisions to engage with extension activities. To understand farmer segments and how these factors vary in order to develop recommendations for future extension delivery.

Methodology: Qualitative data was obtained through semi-structured interviews with 30 Tasmanian dairy farmers. The Theory of Planned Behaviour (TPB) framework was used to identify and explore factors influencing farmer engagement intentions and behaviour.

Findings: There was a negative effect of social influence on experienced farmers’ intention to re-engage with extension, due to the belief extension activities were targeted to less experienced, younger farmers. Perceived control factors limiting engagement included lack of confidence about existing knowledge, resulting in farmers perceiving extension activities as confronting.

Practical implications: Key factors influencing intention to engage and continued engagement with extension were identified. These findings will inform future design and targeting of extension activities to improve initial and continued engagement. Subsequent recommendations are presented.

Theoretical implications: Previous TPB studies on adoption as an outcome of extension have typically focused on quantifying adoption predictions, rather than exploring how social factors interact and influence intentions and behaviours. This paper demonstrates how the TPB can be qualitatively applied to better understand farmer decision making, in this instance with respect to their initial and continued engagement with extension.

Originality/value: This paper demonstrates how the TPB can provide an evidence-based framework to qualitatively explore farmer intentions and behaviour. This approach has led to new insights into farmer decision making that will inform improvements in future extension development.  相似文献

Seizing the Moment: Reflections on Play Opportunities for Disabled Children in the Early Years     

Alison Bishop  John Swain  & Hazel Bines 《British Journal of Educational Studies》1999,47(2):170-183

Current policy in relation to special needs prioritises early intervention and inclusive education, at least as 'good intentions' This article argues for a paradigmatic shift away from individualist models of learning and disability. The social context of play is emphasised as the crucial arena for realising such good intentions, as long as it is geared to responding to, and developing, the self-determination, control, and identity of young disabled children becoming disabled adults in a disabling society.  相似文献

Portfolio Assessment as National Policy: the National Council for Vocational Qualifications and its quest for a pedagogical revolution     

Alison Wolf 《Assessment in Education: Principles, Policy & Practice》1998,5(3):413-445

The National Council for Vocational Qualifications established assessment procedures for qualifications in England, Wales and Northern Ireland in which portfolios play a central role. The relevant qualifications (National Vocational Qualifications and General National Vocational Qualifications) have been taken by large numbers of young people in upper secondary schooling, and young people and adults in work or in government training schemes; and are intended to have labour market currency and to provide routes into further and higher education. The use of portfolios derives from a commitment to direct and comprehensive assessment of the whole ‘syllabus’, but also from a belief in certain pedagogical approaches and in enhancing students' independence and initiative. There is evidence that the approach has affected learning styles, but major problems have arisen relating to the manageability of the approach and the reliability of assessor judgements.  相似文献
