The purpose of this study was to determine the degree of consistency in behavioral state organization for 30 low-risk human participants examined as fetuses at 38–40 weeks gestation and again as neonates at approximately 2 weeks postnatal age. behavioral states were assigned similarly for fetuses and neonmates in terms of heart rate pattern and the presence or absence of eye and gross body movements. We found that the time spent in a sleep period was distributed among quiet sleep (QS), active sleep (AS), and indeterminate states in virtually identical proportions for fetuses and neonates. However, the only within-subject consistency between the fetal and neonatal periods was in the duration of complete QS epochs. Fetuses made fewer transitions between QS and AS, but neonates had shorter and more structured AS → QS transitions. These findings suggest that, whereas central nervous system processes governing QS do not change appreciably, the control of AS undergoes significant changes in the 4 weeks spannig the fetal and neonatal periods. We believe that the duration of enclosed QS epochs provides the only stable measure of behavioral state development between the prenatal and postnatal periods. 相似文献

This exploratory study investigated the role and importance of peers in providing personal and academic support for Year 11 female students, enrolled in physics and biology. While these areas of support had been identified in earlier research by Holland and Eisenhart (1981), this study attempted to investigate further their importance within an Australian context. Questionnaires, completed by one hundred female students, were analysed using Principal Components Analysis and MANOVA. The statistical analysis found no significant differences between the six relevant factors and science subjects, however, significant differences emerged in relation to schools and particular factors. Subsequently, six interviews were conducted with selected students to elaborate upon the statistical differences that emerged from these results. The interviews corroborated the findings of the quantitative analysis and provided explanations for these differences. Overall, the results of this study suggest that while the supportive role provided by peers is similar regardless of the science subject undertaken by a female student this role varies between schools. 相似文献

Independence and competence define the traditional characteristics of a game warden. External pressure to transform the game warden service into a more culturally and ethnically diverse state law enforcement agency, however, creates tensions surrounding these characteristics in the organization's structurationally defined agency and reflexivity of law enforcement; duality of structure in office memos and citation counts; social integration and institutional reproduction of law enforcement training, use of decoys, and search and seizure procedures; and time-space distanciation of working a 40-hour week or having complete responsibility for a territory. The present study examined how these tensions interact with the traditional assumptions of independence and competence to transform the meaning of these characteristics, and of the game warden service itself. 相似文献

This paper describes a pilot project for the professional development of science teachers, a major aim of which was to update teachers’ science content knowledge. The paper focuses on the rationale and background of the project, the model of inservice education, the arrangements for credentialling and recognising participating teachers, and the findings of the external evaluation of the initial stages of the project. It concludes with a summary of the features of the project which appear to be facilitating the achievement of its aims. 相似文献

ABSTRACTSex education within the formal bounds of school curricula or clinic consultation is traditionally conceived as age-appropriate and accurate information, delivered by a sanctioned adult such as a nurse or teacher. This article explores another kind of curriculum – taught and learned among young men themselves in the kasi (township) in which they live. Findings are based on primary data gathered during interviews and research workshops with boys and young men (aged 14–22), including focus group discussions and participatory research exercises. In exploring young men’s sexual ideas, practices, hopes and fears, it focuses on three themes: (i) consent and coercion; (ii) pleasure and risk; and (iii) advice and authority. We examine diverse perspectives on these themes, and trace the tensions and ambiguities that surface within young men’s accounts. We focus in particular on contradictions between what is learned about sex through formal curricula, and what is learned through peers and older men, including within ulwaluko (a rite of passage of traditional initiation and circumcision for Xhosa men). 相似文献

The health benefits of playing football and the importance of exercise and social contact for healthy ageing are well established, but few older adults in the UK take enough exercise. Football is popular, flexible in format and draws players into engrossing, effortful and social exercise, but the physical demands of play at full speed may make it unsustainable for some older adults. Restricted to walking pace, will play still be engaging? Will health benefits be retained? Will physical demands remain manageable? This pilot study aims to investigate: (1) the experience of older adults playing walking football every week, is it sustainable and rewarding, (2) the intensity and locomotor pattern of walking football, (3) the scale and nature of walking football health benefits and (4) possible cognitive benefits of playing walking football through measures of processing speed, selective and divided attention and updating and inhibition components of executive function. ‘Walking football’ and ‘waiting list’ groups were compared before and after 12 weeks of one-hour per week football. Walking football was found to be engaging, sustainable for older adults and moderately intensive; however, selective health and cognitive benefits were not found from this brief intervention.Highlights
Walking football is a lower impact but authentic form of football that enables older players to extend their active participation.
Walking football is enjoyable and moderately demanding and may be a sustainable form of exercise for older adults.
Health and cognitive benefits to playing walking football were not found.

'Playing for Success' is a national initiative to establish Study Support Centres in professional football clubs, intended to support underachieving young people at key stages 2 and 3. The second year of the evaluation involved collection of data from pupils in 12 such Centres. Instruments were administered before and after attendance at the Centres, and measurements taken relating to literacy and numeracy, as well as attitude scales and self-assessments of ICT skills. Data were also obtained from a small 'control' group. Multilevel analysis of the results has given insights into the areas where the initiative appears to have had positive effects, and the other factors which may be associated with such effects. 相似文献
