The importance of shared environment in mother-infant attachment security: a behavioral genetic study 总被引:1,自引:0,他引:1

In a sample of 157 monozygotic and dizygotic twins, genetic and environmental influences on infant attachment and temperament were quantified. Only unique environmental or error components could explain the variance in disorganized versus organized attachment as assessed in the Ainsworth Strange Situation Procedure. For secure versus nonsecure attachment, 52% of the variance in attachment security was explained by shared environment, and 48% of the variance was explained by unique environmental factors and measurement error. The role of genetic factors in attachment disorganization and attachment security was negligible. Genetic factors explained 77% of the variance in temperamental reactivity, and unique environmental factors and measurement error explained 23%. Differences in temperamental reactivity were not associated with attachment concordance. 相似文献

Instructional design is at the heart of each educational endeavour. This process revolves around the steps through which the thoughtful productions of superior products are created. The ADDIE generic instructional design model emphasises five basic steps within the instructional design process: analyse, design, develop, implement and evaluate. The simplistic nature of the ADDIE model, including the ease of application and possibilities towards the cyclical features of the process, enable a more holistic overview of the instructional design process. The Eternal, Synergistic Design Model emphasises the non‐linear nature of the instructional design process. The continuous design and development focuses upon the core evaluation of the product, wherein the Pareto principle emphasises the feedback related to the 20% of difficulties while maintaining an eye upon the 80% neutral and positive aspects of the product. 相似文献

The benefits of cooperative learning strategies, such as group project work, have been advocated in a wide range of educational
contexts. There is however, scant information on the outcome of such programs on students of low academic ability. In this
study, interviews were conducted with four groups of low-ability students, with the aim of investigating their perceptions
on the effectiveness of group project work in promoting their social and cognitive skills. Our findings show that although
the students recognized that the program improved their competence in interacting with others, there are problematic organizational
and instructional issues that have to be ironed out before students can profit fully from cooperative learning programs. 相似文献

AbstractThis article explores changes of environmental values and beliefs among secondary school business and economics students regarding government and market solutions to climate change. The quantitative study is longitudinal and a survey was administrated to students at two occasions including 212 participants in the first measurement. Results show a small significant increase in importance for altruistic, biospheric and egoistic value orientations at average. At an individual level, there are substantial movements over time. Nearly two-thirds of the students changed the strength of their value orientations over time. Taxes and legislation were regarded as the most effective solutions to climate change, however there was a decrease in seeing market prices as important mechanisms for change. Analysis suggested no direct relationship between change in environmental value orientation and change in norms. However indirect associations were mediated by changing beliefs in the efficacy of education and information and the efficacy of tax policies. For example, students who became more egoistic and more convinced about the efficacy of tax were less likely than others to be willing to take personal actions. 相似文献

This study responds to Nado Aveling's call in ‘Anti-racism in Schools: A question of leadership?’ (Discourse: Studies in the Cultural Politics of Education, 2007, 28(1), 69–85) for further investigation into racism in Australian schools. Aveling's interview study concluded that an overwhelming number of school principals denied the presence of racism in their schools, and that there were no discernible differences in how principals in different schools constructed racism. In contrast, our research found that school principals' constructions of cultural racism are strongly influenced by their school contexts. We elucidate these differences examining the various intersections between race, class and religion deployed by principals in different sites, and argue for the utility of examining and theorising cultural racism using an intersectional approach. By bringing context into our analysis we provide a more nuanced insight into the different ways in which racism is constituted and understood by Australian school principals. 相似文献

The rapid changes facing higher education are placing increased focus on the quality of the student experience, achieving learning outcomes, and employability expectations. As a result, academics in teaching roles are increasingly measured on performance via student evaluations amplifying attention on professional development initiatives for academics. One such initiative is the Peer Assisted Teaching Scheme currently in practice across many Australian universities. The critical component of the scheme is the establishment of teaching goals that provide focus and direction for the peer partnership. This study addresses two questions: (1) Around which aspects do academics set their goals for teaching improvement? and (2) How do academics’ goals align with the SMART goal-setting framework that is prescribed in the scheme? Findings from five Australian universities showed that goals align with a variety of educational areas yet many were underdeveloped, or misaligned with the proposed strategy. The implications of this are discussed and a framework for setting education goals for teaching improvement is developed. 相似文献

Background
The most current objectively derived search filters for adverse drug effects are 15 years old and other strategies have not been developed and tested empirically.Objective
To develop and validate search filters to retrieve evidence on adverse drug effects from Ovid medline and Ovid Embase.Methods
We identified systematic reviews of adverse drug effects in Epistemonikos. From these reviews, we collated their included studies which we then randomly divided into three tests and one validation set of records. We constructed a search strategy to maximise relative recall using word frequency analysis with test set one. This search strategy was then refined using test sets two and three and validated on the final set of records.Results
Of 107 systematic reviews which met our inclusion criteria, 1948 unique included studies were available from medline and 1980 from Embase. Generic adverse drug effects searches in medline and Embase achieved 90% and 89% relative recall, respectively. When specific adverse effects terms were added recall was improved.Conclusion
We have derived and validated search filters that retrieve around 90% of records with adverse drug effects data in medline and Embase. The addition of specific adverse effects terms is required to achieve higher recall. 相似文献538.
The effectiveness of phonological instruction with 6 deaf students in an oral program was investigated. In a previous investigation (Syverud, Guardino, & Selznick, 2009), promising results had been obtained in a case study in which the Direct Instruction curriculum titled Teach Your Child to Read in 100 Easy Lessons (Engelmann, Haddox, & Bruner, 1983) was used with an oral-deaf child. Given these results, Syverud and Guardino were asked to replicate the procedures with additional struggling readers. A multiple case study design was implemented for a period of 10 weeks. Tests of nonsense words were administered to monitor weekly progress in phonological decoding. Intervention journals were completed for each tutoring session to provide qualitative information. Although the results were mixed, all 6 participants showed gains in phonological decoding skills. Suggestions for both practitioners and researchers are offered. 相似文献

The purpose of this paper was to present and evaluate a methodology to determine the contribution of bilateral leg and pole thrusts to forward acceleration of the centre of mass (COM) of cross-country skiers from multi-dimensional ground reaction forces and motion capture data. Nine highly skilled cross-country (XC) skiers performed leg skating and V2-alternate skating (V2A) under constant environmental conditions on snow, while ground reaction forces measured from ski bindings and poles and 3D motion with high-speed cameras were captured. COM acceleration determined from 3D motion analyses served as a reference and was compared to the results of the proposed methodology. The obtained values did not differ during the leg skating push-off, and force–time curves showed high similarity, with similarity coefficients (SC) >0.90 in the push-off and gliding phases. In V2A, leg and pole thrusts were shown to contribute 35.1 and 65.9% to the acceleration of the body, respectively. COM acceleration derived from ground reaction forces alone without considering the COM position overestimated the acceleration compared to data from motion analyses, with a mean difference of 17% (P < 0.05) during leg push-off, although the shapes of force–time curves were similar (SC = 0.93). The proposed methodology was shown to be appropriate for determining the acceleration of XC skiers during leg skating push-off from multi-dimensional ground reaction forces and the COM position. It was demonstrated that both the COM position and ground reaction forces are needed to find the source of acceleration. 相似文献
