Changes in workload are evident during many physical activities. The aim of this study was to assess total substrate metabolism when the temporal placement of a period of higher-intensity work (75% VO2max) was varied within a low-intensity exercise session (50% VO2max). One experimental trial (higher intensity first) comprised 5 min low-intensity work, followed by 15 min high-intensity work, followed by 40 min low-intensity work. The other trial (low intensity first) comprised 40 min low-intensity work, followed by 15 min high-intensity work, followed by 5 min low-intensity work. The trials were designed to achieve an identical total energy expenditure. Energy expenditure, fat and carbohydrate utilization were estimated by expired gas analysis and compared between conditions. Mean total energy expenditure during the higher-intensity phase was 1076 kJ and 1128 kJ in the high-intensity first and low-intensity first trials respectively (t6 = -3.76, P = 0.0047). Mean total energy expenditure for the whole trial was 3356 kJ and 3452 kJ in the high-intensity first and low-intensity first trials respectively (t6 = -3.48, P = 0.0065). Mean whole-trial fat utilization was 1753 kJ and 1857 kJ in the high-intensity first and low-intensity first trials respectively (t6 = -0.76, P = 0.24). Our findings suggest that changing the temporal placement of higher-intensity work within a low-intensity exercise session has a significant effect on total energy expenditure but not on the rate of fat oxidation.  相似文献

Educational writing commonly announces new approaches that lay claim to conforming with children's natural learning and development. Almost invariably such approaches repeat principles that were given a modern form in the 1850s in the writings of Herbert Spencer. His great but unacknowledged influence has discouraged recognition that humans are odd creatures whose natural forms of learning and development are buried under layers of cultural acquisitions. Understanding education requires a richer understanding of our cultural tools. Technical expertise in the tasks of education is wasted unless one understands the cultural tools that shape the proper purposes of educational activity.  相似文献

The part-time solo librarian at St. James Healthcare in Butte, Montana, serves physicians, staff, patients, and other health care professionals in the area. The library is part of the Education Department within the hospital's organizational structure. Recent developments have expanded the requirements of the Education Department, creating new challenges. The librarian is a member of the team developing solutions to the many ways that continuing education needs have to be met for the staff and physicians. A free website that houses education information and material is one of the projects that has been created and is maintained by the librarian.  相似文献

In order to assess the possible occurrence of acute haemolysis with prolonged exertion, serum haptoglobin levels were determined from venous blood samples collected from eight male runners immediately preceding (PreRH), immediately following (PRH1), and 6 h following (PRH2) completion of a marathon road race. The subjects’ mean age, percentage of body fat, and maximum oxygen uptake (VO2max) were 46 ± 9 years, 12.1 ± 3.4% and 54.9 ± 8.4 ml kg‐1 min‐1, respectively. The mean race finish time for the subjects was 3:35 ± O: 18 h:min. The PreRH, PRH1 and PRH2 averaged 129 ± 18, 97 ± 48 and 86 ± 35 mg dl‐1 respectively. Significant differences of –32.5 mg dl‐1 between PreRH versus PRH1 and –42.5 mg dl‐1 between PreRH versus PRH2 were found. The difference between PRH1 and PRH2 of –10.6 mg dl‐1 was not significant. No significant correlations were found between the decreases in serum haptoglobin and VO2max or race finish time. The data suggest the occurrence of an acute haemolysis with performance of the marathon road race.  相似文献

Schools have the potential to provide a place of education and sanctuary for children and young people of all backgrounds. The rise in mental health problems in children and young people in the wake of the COVID-19 pandemic, particularly in relation to growing inequities, means that identifying ways in which schools can help respond to this growing mental health crisis demands urgent attention. This paper reports on case studies carried out in two London comprehensive schools, exploring how aspects of school culture impact (both positively and negatively) on student mental health. Methods comprised in-depth interviews with school staff and parents, focus groups with students and documentary analysis of relevant materials. Fieldwork was conducted during spring 2021 as schools were returning to face-to-face learning following national periods of lockdown. Our study shows how schools might attempt to drive positive mental health outcomes through aspects of school culture and uses a system framework to explore complexities around cause and effect in this area. Key findings include the considerable differences in school mental health provision, challenges in the identification of student mental health needs and the importance of recognising how the mental health of teachers must be considered alongside that of students. Overall, we highlight particular dilemmas of the post-lockdown era that our findings indicate for the education sector, and suggest there may be value in reframing the apparent conflict between ‘attainment gaps’ and personal development, moving towards an educational approach with greater complementarity of these aims.  相似文献

Although there is evidence for specific risk factors leading to child sexual exploitation and prostitution, these influences overlap and have rarely been examined concurrently. The present study examined case files for 175 young persons who attended a voluntary organization in Leicester, United Kingdom, which supports people who are sexually exploited or at risk of sexual exploitation. Based on the case files, the presence or absence of known risk factors for becoming a sex worker was coded. Data were analyzed using t-test, logistic regression, and smallest space analysis. Users of the voluntary organization's services who had been sexually exploited exhibited a significantly greater number of risk factors than service users who had not been victims of sexual exploitation. The logistic regression produced a significant model fit. However, of the 14 potential predictors – many of which were associated with each other – only four variables significantly predicted actual sexual exploitation: running away, poverty, drug and/or alcohol use, and having friends or family members in prostitution. Surprisingly, running away was found to significantly decrease the odds of becoming involved in sexual exploitation. Smallest space analysis of the data revealed 5 clusters of risk factors. Two of the clusters, which reflected a desperation and need construct and immature or out-of-control lifestyles, were significantly associated with sexual exploitation. Our research suggests that some risk factors (e.g. physical and emotional abuse, early delinquency, and homelessness) for becoming involved in sexual exploitation are common but are part of the problematic milieu of the individuals affected and not directly associated with sex trading itself. Our results also indicate that it is important to engage with the families and associates of young persons at risk of becoming (or remaining) a sex worker if one wants to reduce the numbers of persons who engage in this activity.  相似文献

Both local and global issues are typically dealt with in the Social Studies curriculum, or in curriculum areas with other names but similar intents. In the literature about Social Studies the imagination has played little role, and consequently it hardly appears in texts designed to help teachers plan and implement Social Studies lessons. What is true of Social Studies is also largely reflected in general texts concerning planning teaching. Clearly many theorists and practitioners are concerned to engage students' imaginations in learning, even though they use terms other than 'imagination' in doing so. This article suggests that a more explicit attention to imagination can make our efforts to engage students in learning more effective. We provide, first, a working definition of imagination, then show how students' imaginations can be characterized in terms of the 'cognitive toolkits' they bring to learning. We look at such 'cognitive tools' as stories, images, humor, binary oppositions, a sense of mystery and how these can be used to engage students' imaginations in learning Social Studies and other content from kindergarten to about grade four. We then consider 'cognitive tools' commonly deployed by students from about grade four to grade nine, including a sense of reality, the extremes of experience and limits of reality, and associating with the heroic. We also provide examples of how using such tools could influence planning and teaching Social Studies topics.  相似文献

In this article we introduce a usage-goal framework within which task design can be guided and analyzed. We tell a tale of one task, the Pentomino Problem, and its evolution through predictive analysis, trial, reflective analysis, and adjustment. In describing several iterations of the task implementation, we focus on mathematical affordances embedded in the design and also briefly touch upon pedagogical affordances.  相似文献
