ABSTRACT

This article investigates how cultural businesses may facilitate contentious political activity in authoritarian contexts. Existing research in Western liberal democracies has shown the widespread political activism of actors in the cultural and creative industries. Whether such activism exists in authoritarian society, how it may differ in character and form, and what implications this will have for our understanding of relations between business, politics, and culture in authoritarian countries remain to be addressed. Drawing on data collected from 55 ‘independent bookshops’ in China, I illustrate how these organisations perform ‘cultural politics,’ a type of political participation in which actors employ mainly symbolic means to express social and political concerns. The organisations’ economic relations and conditions facilitate their efforts to create spaces in which contentious questions can be raised, sensitive topics explored, and alternative ideas expressed, despite the Chinese state’s political regulation of the cultural sphere. The finding of the economic embeddedness of cultural politics sheds new light on our understanding of the political economy of cultural businesses in contemporary China.  相似文献

ABSTRACT

Background: Schoolchildren’s personality development is considered a central goal of physical education (PE). With regard to the relationship between psychological well-being and global self-esteem over the life course, the promotion of positive self-esteem is an issue of particular significance. Past research revealed that PE taught with an individualized teacher frame of reference (iTFR) and a reflexive teaching style is associated with positive effects on facets of children’s perceived sports competence. However, it remains an open question whether this teaching styles has the potential to promote positive self-esteem.

Purpose: The present study investigated whether a five-month teacher training, aimed to enhance the teachers’ iTFR and their reflexive teaching style in PE, has a positive effect on students’ perceived sports competence and their global self-esteem. To analyse the implementation quality, changes in students’ perceived iTFR and perceived reflexive teaching style were investigated.

Method: A total of 21 teachers were assigned to either an intervention group (n?=?13), receiving the five-month teacher training, or a control group (n?=?8) consisting of regular teaching without teacher training. The teacher training encompassed five three-hour consecutive sessions during which the teachers acquired theoretical and practical knowledge about the promotion of competence perceptions in PE with a reflexive teaching style and an iTFR. Between the sessions, the teachers were instructed to implement an iTFR and a reflexive teaching style into their own PE classes. To evaluate the effects of the teacher training, their students’ (N?=?315, 53.7% girls, Mage?=?13.2 y, SDage?=?1.3 y) perceived teaching style (iTFR and reflexive teaching), perceived sports competence and global self-esteem were measured with paper-pencil questionnaires at three measurement points (pre, post and follow-up).

Findings: Linear mixed effect models showed that students of the intervention group reported an increase in their teachers’ reflexive teaching style, but there were no changes with regard to iTFR. With regard to students’ perceived sports competence and global self-esteem, there were significant interaction effects between time and group over a period of eight months (from pre-test to follow-up), indicating positive effects on these self-concept dimensions due to the teacher training.

Conclusion: The present study indicates that a long-term teacher training supports PE teachers to implement teaching styles with the aim to promote students’ self-concept. Furthermore, the findings lead to the assumption that a more pronounced iTFR in combination with an enhanced reflexive teaching style has the potential to positively influence schoolchildren’s perceived sports competence and global self-esteem.  相似文献

BackgroundOne-hour postprandial hyperglycemia is associated with increased risk of type 2 diabetes and cardiovascular disease. Physical activity (PA) has short-term beneficial effects on post-meal glucose response. This study compared the oral glucose tolerance test results of 3 groups of people with habitually different levels of PA.MethodsThirty-one adults without diabetes (age 25.9 ± 6.6 years; body mass index 23.8 ± 3.8 kg/m2; mean ± SD) were recruited and divided into 3 groups based on self-reported PA volume and intensity: low activity < 30 min/day of moderate-intensity activity (n = 11), moderately active ≥ 30 min/day of moderate-intensity PA (n = 10), and very active ≥ 60 min/day of PA at high intensity (n = 10). Participants completed an oral glucose tolerance test (50 g glucose) with capillary blood samples obtained at baseline, 15 min, 30 min, 45 min, 60 min, 90 min, and 120 min post-ingestion.ResultsThere were no significant differences between groups for age or body fat percentage or glycated hemoglobin (p > 0.05). The groups were significantly different in terms of baseline glucose level (p = 0.003) and, marginally, for gender (p = 0.053) and BMI (p = 0.050). There was a statistically significant effect of PA on the 1-h postprandial glucose results (p = 0.029), with differences between very active and low activity groups (p = 0.008) but not between the moderately active and low activity groups (p = 0.360), even when baseline glucose level and gender differences were accounted for. For incremental area under the curve there was no significant effect of activity group once gender and body fat percentage had been accounted for (p = 0.401). Those in the low activity group took 15 min longer to reach peak glucose level than those in the very active group (p = 0.012).ConclusionThe results suggest that high levels of PA have a beneficial effect on postprandial blood glucose profiles when compared to low and moderate levels of activity.  相似文献

运用双框架模型对中美竞技体育国际竞争力进行比较研究。认为:①从显现性框架分析,美国竞技体育国际竞争力一直稳定处于高位,而中国则呈现以2008年为峰顶的倒“U”型发展特征,且与美国还存在一定差距;②从解释性框架分析,美国竞技体育国际竞争力已趋于顶峰,而中国稳步提升;③中国竞技体育发展潜力巨大,但短时间内难以赶超美国;④“举国体制”有利于中国竞技体育显现性竞争力的提升,但与美国社会办竞技体育的发展模式相比,市场、社会在竞技体育发展中的作用发挥不足,不利于高经济性项目、高欣赏性项目的发展;⑤坚持“举国体制”、承办2022年冬奥会有利于中国竞技体育显现性竞争力的提升和冬季项目的发展,但同样存在竞技体育项目布局转型的困难和群众体育基础薄弱的困境。  相似文献

纳粹统治时期种族主义盛行,体育运动也未能自外其中,沦为国家政治的工具。而体育术语本土化的规范,似是黑暗政治中的一道学术微光。本文采用文献分析法,以1936年柏林奥运会及《奥林匹克手册》为例,对该时期的德国体育战略及体育语言工作进行分析。  相似文献

Abstract

Institutional repositories (IRs) present platform to disseminate research findings to complement the traditional scholarly communication model. The use of IRs is beneficial to authors, host institutions, libraries and society at large. Despite the numerous benefits of IRs, there is low deposit of scholarly works by lecturers and the investment on IRs seems to be a waste. This study examined determinants of perceived ease of use (PEOU) of IRs by lecturers in Nigerian universities. A survey of lecturers received 857 respondents. Awareness, anchor and adjustment factors were found to be determinants of PEOU of Institutional repositories by lecturers in Nigerian Universities.  相似文献

为探讨区域体育产业发展与健康中国建设耦合协调度及未来前景,在分析体育产业与健康中国耦合作用机理的基础上,构建体育产业与健康中国耦合协调发展评价体系,运用熵值法、耦合协调模型和修正GM(1.1)预测法对我国东部地区11省市2013—2017年两大系统耦合协调关系进行实证分析,并预测未来10年两大系统的耦合协调关系。研究发现(1)区域体育产业发展与健康中国建设之间存在明显的相互影响、相互作用关系,耦合协调发展特征显著。(2)东部地区11省市两大系统发展水平总体呈上升态势,且二者具有较高的关联性;体育产业系统发展水平比健康中国系统波动性更强,体育产业成为缩小区域发展差异的有效路径依赖;体育产业发展对健康中国建设的驱动作用较弱,而健康中国建设对体育产业发展促进作用较大。(3)东部地区11省市两大系统耦合协调性在逐年稳步上升,但演进与提升速度较缓慢,协调关系始终处在勉强协调阶段,且耦合协调度存在较大的空间差异,从北向南的空间格局大体上呈现“高—较高—高—较高—高—低”,预测结果显示未来10年耦合协调水平演进与提升速度明显加快,但仍存在显著的空间差异。并提出建议,以期服务实践。  相似文献
