This paper highlights the strengths of giving visibility to the concepts of space and time in research related to women's lives and higher education. It is based on research that explores the everyday practice and experience of women higher education students at a community college in the north of England. It focuses on the ways in which space and time to study are both socially and personally constructed. The concepts of space and time are drawn on to theorize and analyze women students' experiences and to draw attention to the ‘behind scenes of power and control’ shaping action (Layder, 1993 Layder D 1993 New strategies in social research (Cambridge, Polity)  [Google Scholar], p. 249). Women students from a range of backgrounds are considered, including younger/older, mother/non‐mother and differential class and geographical heritage. The paper highlights three issues. Firstly, the increasingly restricted ground available for academic studies in women's lives, resulting from the restructuring of paid work, social welfare and higher education. Secondly, the hierarchy of values and ambiguous meanings attached to higher education when women attempt to study. Thirdly, the intense negotiations undertaken by women students in order to construct space and time for academic work.  相似文献

Drawing on anthropological evidence that interactions with texts are often mediated through oral language practices and Vygotsky's ideas about the primacy of social dialogue for individual intellectual development, the authors argue that children's informal talk about both electronic and printed texts throws new light on the reading process as a whole. They analyse children's talk about a school library book, a piece of graffiti, a television programme and a film to show how readings are shaped by the social organization and personal relationships of the readers, whether in curriculum activities, friendship groups or at home in the family. Readings are constructed, contested and negotiated through talk at the point where texts are first calculated and reshaped again when they are jointly recalled. Talk also helps to construct the text's legitimate audience and the reader's position within it.  相似文献

The contribution of attachment, maternal reported stress, and mother-child interaction to the prediction of teacher-reported behavior problems was examined for a French-Canadian sample of 121 school-age children. Attachment classifications were assigned on the basis of reunion behavior with mother when the children were between 5 and 7 years of age. Maternal reported stress and mother-child interaction patterns were assessed concurrent to the attachment measure, whereas behavior problems were evaluated both at ages 5 to 7 and 7 to 9 years. Security of attachment significantly predicted the likelihood of school-age behavior problems: Controlling/other children were most at risk for both externalizing and internalizing problems across both age periods. Younger ambivalent children presented clinical cut-off levels of externalizing problems, and older avoidant boys had higher internalizing scores. Patterns of maternal-reported stress and mother-child interaction differed across attachment groups and contributed to prediction of school-age behavior problems, partially mediating the relation between attachment and adaptation. Results support the importance of attachment in explaining school-age adaptation and validity of attachment coding for children of this age.  相似文献

Within the Canadian context, the physical activity levels of children and youth in the after school time period has become a source of public health concern. We argue that this concern is informed by broader public health crises, in particular the ‘global obesity epidemic’ and the closely related ‘global pandemic of physical inactivity', and that these so-called ‘crises’ operate as part of a discursive regime that serves to justify after school interventions aimed at increasing the physical activity practices of children and youth. Although the objectives of such interventions are seemingly well intentioned, we suggest that such interventions nonetheless harbor difficult to discern, but potentially pernicious consequences, for the communities in which they are implemented. We focus our attention on the place-specific effects of one Public Health Agency of Canada-funded after school physical activity intervention – After the School Bell Rings (ASBR) – that was implemented in the mostly Indigenous, northern community of Placid, Manitoba. Based on a critical analysis of the ASBR program itself, along with interviews and focus groups with children, parents and recreation providers (n?=?10) from the community of Placid, we contend that the ASBR serves to govern Indigenous recreation at a distance. We argue that when implemented in the place-specific context of Placid, the ASBR functions as part of a broader governmental assemblage composed of loosely connected discourses, institutions, socio-structural conditions and individuals that, when assembled, ultimately serve to govern geographically and culturally distinct communities. We conclude by suggesting that the objectives of broad-based health interventions, such as the goal of increasing after school physical activity levels, should not be universally implemented across diverse locales, but need to account for the diverse, place-specific priorities and needs of the communities into which they are implemented.  相似文献

Abstract

In this study, we examined the effects of different work:rest durations during 20 min intermittent treadmill running and subsequent performance. Nine males (mean age 25.8 years, s = 6.8; body mass 73.9 kg, s = 8.8; stature 1.75 m, s = 0.05; [Vdot]O2max 55.5 ml · kg?1 · min?1, s = 5.8) undertook repeated sprints at 120% of the speed at which [Vdot]O2max was attained interspersed with passive recovery. The work:rest ratio was constant (1:1.5) with trials involving either short (6:9 s) or long (24:36 s) work:rest exercise protocols (total exercise time 8 min). Each trial was followed by a performance run to volitional exhaustion at the same running speed. Testing order was randomized and counterbalanced. Heart rate, oxygen consumption, respiratory exchange ratio, and blood glucose were similar between trials (P > 0.05). Blood lactate concentration was greater during the long than the short exercise protocol (P < 0.05), whereas blood pH was lower during the long than the short exercise protocol (7.28, s = 0.11 and 7.30, s = 0.03 at 20 min, respectively; P < 0.05). Perceptions of effort were greater throughout exercise for the long than the short exercise protocol (16.6, s = 1.4 and 15.1, s = 1.6 at 20 min, respectively; P < 0.05) and correlated with blood lactate (r = 0.43) and bicarbonate concentrations (r = ?0.59; P < 0.05). Although blood lactate concentration at 20 min was related to performance time (r = ?0.56; P < 0.05), no differences were observed between trials for time to exhaustion (short exercise protocol: 95.8 s, s = 30.0; long exercise protocol: 92.0 s, s = 37.1) or physiological responses at exhaustion (P > 0.05). Our results demonstrate that 20 min of intermittent exercise involving a long work:rest duration elicits greater metabolic and perceptual strain than intermittent exercise undertaken with a short work:rest duration but does not affect subsequent run time to exhaustion.  相似文献

The Type A behaviour pattern is a well‐documented, if controversial, risk factor for coronary heart disease. Surprisingly, relatively little work has been reported on ways of modifying this behaviour pattern. Aerobic exercise, with its demonstrated benefits for both cardiovascular reactivity and psychological ‘well‐being’, is a promising treatment. The literature is reviewed and recommendations are made for practical applications and future research.  相似文献

This article considers how knowledge, education and research interact as the institutional structures that support them change. Many efforts at large‐scale education reform depend upon the proposition that what counts as useful knowledge can be easily defined, without reference to the specific contexts in which that knowledge will be set to work. Yet ?useful knowledge’ as it appears to policymakers does not always translate into ?useful knowledge’ from the perspective of practitioners. Distance and context matter. Based on studies of the development of literacy policy in England under successive governments, the paper assesses the dislocations and divisions of labour that characterise the contemporary knowledge landscape and asks how the research community can continue to act for the common good in an increasingly crowded and contested education field.  相似文献

The article describes a survey of the attitudes of sixth form students towards an Advanced level course in sociology taught by open learning strategies. The problems of open learning for the 16–19 year age group are highlighted and suggestions made for the use of key questions in performance monitoring which may identify learning difficulties for other open learners in this age group. The findings suggest that younger students entering such open learning programmes may need study methods counselling and additional tutorial support.  相似文献
