Physical Activity as a Natural Antioxidant Booster and its Effect on a Healthy Life Span     

Helaine M. Alessio  Eileen R. Blasi 《Research quarterly for exercise and sport》2013,84(4):292-302

Abstract

The recent Surgeon General's report (U.S. Department of Health and Human Services, 1996) promotes regular physical activity to enhance health. A possible mechanism by which physical activity contributes to a healthy life span is via enhanced antioxidant status. The purpose of this paper is to summarize findings from human studies on life span, health, antioxidants, and the effectiveness of physical activity as a natural antioxidant booster. Epidemiological studies concur that some antioxidants are inversely related to mortality. A single bout of exercise elevates some antioxidant enzyme and coenzyme activities. Regular physical activity enhances some antioxidants; however, strenuous exercise may diminish others. Results generally show that antioxidants play a mediating role in the way in which physical activity positively affects a healthy life span.  相似文献   

The quest for higher education by the Chinese middle class: retrenching social mobility?     

Eileen Yuk-ha Tsang 《Higher Education》2013,66(6):653-668

This article examines how and why the Chinese second-generation middle class, who are unable to obtain admission in China’s premier universities, turn their back on other public universities and instead attend private universities in their country. It finds that their parents capitalize on their privileged guanxi (connections) to send their children to private universities and then study abroad to secure a generational reproduction of their class status and mobility. The Chinese new middle class families look upon joint-partnership private universities as the stepping stone for overseas study. In addition, this article examines how extant Western class theories, including Weberian, Neo-Weberian, and Bourdieuian theories, cannot provide an adequate account of class formation and the generational stratification in present-day China. To explain this reproduction of class in contemporary China, this paper explores how and why the Maoist social institutions of danwei (work unit) and hukou (household registration) still matter in post-reform China in determining middle class’s life chance. Seen in this light, the progenies of cadres and skilled professionals are the main beneficiaries of economic reform.  相似文献   

Conventional wisdom,course choice and student progress in science courses     

Shelagh Ross  Eileen Scanlon 《Open Learning》2013,28(3):14-22

Shelagh Ross, Staff Tutor in Science in the Open University's East Anglian Region, and Eileen Scanlon, Lecturer in the Open University's Institute of Educational Technology, have conducted a study of course choice for Science Faculty students. They asked the question as to whether Science Foundation course students select fairly traditional degree profiles of an ‘all Science’ tendency, or whether they range more freely across a range of subjects, and secondly, what role taking one or two Foundation courses played in contributing to success.  相似文献   

Curriculum continuity in the social studies     

Eileen Harries 《Education 3-13》2013,41(2):46-50

Class size continues to rise in primary schools with many more children now being taught in large classes. Even so, the relationship between class size and children's access to the range of appropriate curriculum activities has been given sparse consideration. Given this neglect, this study was designed to assess teachers' perceptions of the effects of larger classes on children's opportunities to experience the full breadth of the national curriculum.  相似文献   

Organisation in the nursery     

Eileen Smith 《Education 3-13》2013,41(2):41-43

The importance of continuing professional development (CPD) is increasingly recognised as an important contributor to school improvement. Successful CPD involves gaining the commitment of teachers to the process, and to sustaining and supporting their involvement in activities that are beneficial to both their professional growth and the development of their school and the children. This article describes a whole school improvement initiative that sought to do just that: a partnership, in which Hampshire inspection and advisory service; University College, Winchester; and the teachers at Lee-on-the Solent Junior School, worked together to enable practitioner research to become both a reality, and a powerful contributor to both personal development and school improvement.  相似文献   

Contemporary approaches to learning science: technologically-mediated practical work     

Eileen Scanlon  Erica Morris  Terry di Paolo  Martyn Cooper 《Studies in Science Education》2013,49(1):73-114

This paper describes the current state of science education in Arab states and anticipates some of the challenges faced by those states as they reform their science education. After discussing problems of illiteracy, access and quality we provide contextual information about the structure of the educational systems and describe recent efforts to reform them. We focus on issues pertaining to science curriculum and textbooks, language, religion, student learning in science, science teacher education and science education research and summarise the challenges and opportunities for research faced in each area. We conclude the paper by proposing a set of policy and research recommendations that could aid in the development of lasting solutions for recurring problems.  相似文献   

In defence of a pedagogy of the heart: theory and practice in the use of imaginal knowledge     

Eileen Willis  Tania Leiman 《高等教育研究与发展》2013,32(4):660-671

This article outlines one of the theoretical approaches to pedagogy of the heart, drawing specifically on the work of Hillman and his concept of imaginal knowledge. Imaginal knowledge, as opposed to evidence-based and critical pedagogy, illuminates the imagination and moves the heart towards humanistic action. In this paper, we argue that this is an area neglected in the education of professionals. The paper provides a number of methodological strategies for integrating education of the heart with critical and evidence-based knowledge. These strategies deal with how to evoke the imagination and move the heart and then progress to issues of classroom communication and the management of emotions. The context is the teaching of supporting sciences to health professionals in the university sector.  相似文献   

Environmental Education as a Model for Constructivist Teaching     

Elizabeth S. Klein  Eileen Merritt 《The Journal of environmental education》2013,44(3):14-21

Abstract

Current literature related to science instruction often includes a discussion of the philosophy of constructivism. The authors describe four main components of a constructivist science lesson or unit. A review of commonly used environmental education materials was conducted to look for these components. Parallels between teaching strategies used in environmental education and constructivist methods are discussed.  相似文献   

Three Randomized Controlled Trials of Early Long-Chain Polyunsaturated Fatty Acid Supplementation on Means-End Problem Solving in 9-Month-Olds     

James Drover  Dennis R. Hoffman  Yolanda S. Castañeda  Sarah E. Morale  Eileen E. Birch 《Child development》2009,80(5):1376-1384

This study examines whether feeding infants formula supplemented with long-chain polyunsaturated fatty acids (LCPUFA) improves cognitive function of 9-month-olds. Participants included 229 infants from 3 randomized controlled trials. Children received either formula supplemented with docosahexaenoic acid and arachidonic acid, or a control formula beginning at 1–5 days (12-month feeding study), or following 6 weeks (6-week-weaning study) or 4–6 months of breastfeeding (4-to 6-month weaning study). Infants were assessed with a 2-step problem solving task. In the 12-month feeding and 6-week weaning studies, supplemented children had more intentional solutions (successful task completions) and higher intention scores (goal-directed behaviors) than controls. These results suggest that LCPUFA supplementation improves means-end problem solving.  相似文献   

Research: Gender and Race Differences in the Perceptions of Sexual Harassment     

Eric J. Sydell  Eileen S. Nelson 《Journal of College Counseling》1998,1(2):99-110

This study examined the influence of gender and race on the perception of sexual harassment and on recommended punitive measures for the potential harasser by college judicial boards. Significant gender-based differences were found in perception of an ambiguous sexual harassment situation. Significant differences by race of the harasser were not found in the perception of harassment or recommendation of punitive measures. Results suggest a possible shift in race relations among college students as well as differences in the way men and women perceive ambiguous sexual harassment situations. Implications for college counselors and administrators are discussed.  相似文献
