In recent years, multinational food and drink corporations and their marketing practices have been blamed for the global childhood obesity ‘crisis’. Unsurprisingly, these corporations have been quick to refute these claims and now position themselves as ‘part of the solution’ to childhood obesity. In this paper, I examine how and why corporations fund, devise and/or implement ‘healthy lifestyles education’ programmes in schools. By using a critical ethnographic research approach alongside Foucault’s notion of governmentality, I interrogate what those with the ‘will to govern’ (such as corporations) wanted to happen (e.g. fight obesity, change marketing practices and increase consumption), but also what actually happened when these corporatised education programmes met their intended targets in three New Zealand primary schools. I critically examine these programmes by focusing on the ways in which three technologies of consumption – product placement, transforming children into marketers and sponsorship – attempt to govern children to be lifelong consumers of the corporate brand image and their allegedly ‘healthy’ corporate products. Although students were not necessarily naïve and easily coerced into becoming mindless consumers of corporate products, students and their teachers readily accepted that sponsorship, product placement and marketing in schools were normal, natural, necessary and mostly harmless. Healthy lifestyles education programmes represent a new ‘brand’ of health, health education and corporation. The child-citizen is governed to become the child-consumer. Corporations’ anxieties about being blamed for childhood obesity are fused with technologies of ‘healthy consumption’: the consumption of corporate products, corporate philanthropy, the corporate brand and corporate ‘education’. 相似文献

This study investigated protein kinase activation and gene expression of angiogenic factors in response to low-load resistance exercise with or without blood flow restriction (BFR). In a repeated measures cross-over design, six males performed four sets of bilateral knee extension exercise at 20% 1RM (reps per set?=?30:15:15:continued to fatigue) with BFR (110?mmHg) and without (CON). Muscle biopsies were obtained from the vastus lateralis before, 2 and 4?h post-exercise. mRNA expression was determined using real-time RT–PCR. Protein phosphorylation/expression was determined using Western blot. p38MAPK phosphorylation was greater (p?=?0.05) at 2?h following BFR (1.3?±?0.8) compared to CON (0.4?±?0.3). AMPK phosphorylation remained unchanged. PGC-1α mRNA expression increased at 2?h (5.9?±?1.3 vs. 2.1?±?0.8; p?=?0.03) and 4?h (3.2?±?0.8 vs. 1.5?±?0.4; p?=?0.03) following BFR exercise with no change in CON. PGC-1α protein expression did not change following either exercise. BFR exercise enhanced mRNA expression of vascular endothelial growth factor (VEGF) at 2?h (5.2?±?2.8 vs 1.7?±?1.1; p?=?.02) and 4?h (6.8?±?4.9 vs. 2.5?±?2.7; p?=?.01) compared to CON. mRNA expression of VEGF-R2 and hypoxia-inducible factor 1α increased following BFR exercise but only eNOS were enhanced relative to CON. Matrix metalloproteinase-9 mRNA expression was not altered in response to either exercise. Acute low-load resistance exercise with BFR provides a targeted angiogenic response potentially mediated through enhanced ischaemic and shear stress stimuli. 相似文献

In contemporary times, corporate philanthropy is positioned as an effective means to ‘solve’ a variety of social problems. Childhood obesity is one such ‘problem’ that has captured the interests of schools, corporations, industry groups and a number of ‘not-for-profit’ players. In this paper, I critically examine how the private sector uses the notion of philanthropy to shape school-based solutions to obesity and unhealthy lifestyles. By conducting a critical ethnography in two New Zealand primary schools and drawing on Foucauldian notions of government and ‘practices of assemblage’, I illuminate how a number of organisations officially planned to employ philanthropy as a means to govern others, as well as what actually happened when these plans met their intended targets: children, teachers and principals. Although corporations, charities and schools were assembled together through their combined ‘will to give’, the notion of philanthropy helped to re-assemble and re-invent private sector organisations so that they were seen to be socially responsible, healthy, and even educational. Philanthropy also worked to mask private sector players less altruistic interests: branding, public relations strategies, avoidance of stricter regulations and legislation, and the desire to profit. 相似文献

Current concerns about a childhood obesity crisis and children's physical activity levels have combined to justify fitness lessons as a physical education practice in New Zealand primary (elementary) schools. Researchers focused on children's understandings of fitness lessons argue that they construct fitness as a quest for an ‘ideal’ (skinny or muscular) body. The conflation of fitness with thinness, however, is complex and problematic. In this paper, we draw from research conducted with a class of primary school children in New Zealand. Drawing on the theoretical tools of Foucault and utilizing a visual methods approach, we examine how children experience school fitness lessons and construct notions of fitness, health and body. The children's responses illustrated that obesity discourses and body pedagogies ‘collided’ in a way that shaped understandings of fitness lessons in ways inextricably connected with the avoidance of being fat. The children assumed that fitness lessons increased fitness and that being fit was demonstrated by a ‘correct’ corporeal appearance. We argue that body pedagogies inside and outside the school gates shape children's ideas about the body in ways which exclude other understandings of bodies, health, and physical activity. 相似文献

This paper examines the traditional engineering-based provision delivered to Product Design and Technology (B.Sc.) undergraduates at the Loughborough Design School and questions its relevancy against the increasing expectations of industry. The paper reviews final-year design projects to understand the level of transference of engineering-based knowledge into design practice and highlights areas of opportunity for improved teaching and learning. The paper discusses the development and implementation of an integrated approach to the teaching of Mechanics and Electronics to formalise and reinforce the key learning process of transference within the design context. The paper concludes with observations from the delivery of this integrated teaching and offers insights from student and academic perspectives for the further improvement of engineering-based teaching and learning. 相似文献

The purpose was to assess sleep patterns, quantity and quality in adolescent (16.2?±?1.2 yr) Middle Eastern academy soccer players (n?=?20) and the influence of an intermission upon these characteristics. On a 17-day training camp (located one time zone west of home) including three discrete matches, sleep was assessed pre- (PRE) and post-match (POST) via wrist actigraphy. Retrospective actigraphy analysis identified sleep characteristics, including if players experienced a sleep intermission (YES) or not (NO) proximal to dawn, and bedtime (hh:mm), get-up time (hh:mm), time in bed (h), sleep duration (h) and sleep efficiency (%). Within YES two bouts were identified (BOUT1 and BOUT2). No differences were seen between PRE and POST, nor between BOUT1 and BOUT2 (p?>?.05). Overall players did not meet National Sleep Foundation (NSF) guidelines (7:04?±?1:16?h vs. recommended 8–10?h for 14–17 yr). Sleep duration was significantly reduced (~ ?13% or ?1:06) in YES compared to NO (6:33?±?1:05 vs. 7:29?±?1:17, p?<?.01). Despite players in YES waking earlier due to an intermission, they did not compensate for this with a later wake time, rising significantly earlier compared to NO (09:40?±?00:38 vs. 10:13?±?00:40, p?<?.05). These players on average do not obtain sufficient sleep durations relative to NSF guidelines, with decrements increased by an intermission proximal to dawn. High inter- and intra-individual variance in the players sleep characteristics indicates the need for individualized sleep education strategies and interventions to promote appropriate sleep. 相似文献

Application of flipped classroom pedagogy to the human gross anatomy laboratory: Student preferences and learning outcomes 下载免费PDF全文
Timothy R. Fleagle Nicholas C. Borcherding Jennie Harris Darren S. Hoffmann 《Anatomical sciences education》2018,11(4):385-396
To improve student preparedness for anatomy laboratory dissection, the dental gross anatomy laboratory was transformed using flipped classroom pedagogy. Instead of spending class time explaining the procedures and anatomical structures for each laboratory, students were provided online materials to prepare for laboratory on their own. Eliminating in‐class preparation provided the opportunity to end each period with integrative group activities that connected laboratory and lecture material and explored clinical correlations. Materials provided for prelaboratory preparation included: custom‐made, three‐dimensional (3D) anatomy videos, abbreviated dissection instructions, key atlas figures, and dissection videos. Data from three years of the course (n = 241 students) allowed for analysis of students' preferences for these materials and detailed tracking of usage of 3D anatomy videos. Students reported spending an average of 27:22 (±17:56) minutes preparing for laboratory, similar to the 30 minutes previously allocated for in‐class dissection preparation. The 3D anatomy videos and key atlas figures were rated the most helpful resources. Scores on laboratory examinations were compared for the three years before the curriculum change (2011–2013; n = 242) and three years after (2014–2016; n = 241). There was no change in average grades on the first and second laboratory examinations. However, on the final semi‐cumulative laboratory examination, scores were significantly higher in the post‐flip classes (P = 0.04). These results demonstrate an effective model for applying flipped classroom pedagogy to the gross anatomy laboratory and illustrate a meaningful role for 3D anatomy visualizations in a dissection‐based course.
