芡实本属于中国中部、南部各省种植生产,在充分利用芡实的经济价值之外,考虑到芡实对不同富营养化水体水质的改善效果,因此,本试验以芡实为试材,采用人工模拟试验的方法,分析其对不同富营养化等级水体吸收的情况,结果显示:在不同富营养化水体中,总氮的去除率在77.46%~92.84%,总磷的去除率在:64.65%~87.31%。芡实在处理不同浓度的富营养化水体的水质均有良好的效果,可有效去除富营养化湖泊水体中氮磷等营养物质。 相似文献

Capoeira could be defined as a Brazilian martial art and game to be played. This research explored how capoeira play might be considered to facilitate connectedness amongst newly-recruited persons, plus any other ramifications of capoeira involvement. A beginners’ course of capoeira was provided to participants, free of charge, in an English city in the West Midlands—new capoeiristas in a new venue for capoeira. Researchers attended classes to collect/construct overt non-participant observation data. In addition, semi-structured interviews were undertaken with the new capoeiristas post-course. This article explores researchers’ observation fieldnotes and interviewees’ narratives. These qualitative data-driven debates include the concepts: self, identity, escapism, multiparty endeavour, community, temporality, enjoyment, and transcending boundaries. Capoeira is theorised in a fresh manner that highlights social benefits of capoeira—for example as an enjoyable and supportive group endeavour which includes elements of social play and community-building—plus benefits for self that can transcend the boundaries of the class. Findings highlight how capoeira can be considered an inherently multiparty endeavour whereby social actors form, and experience, a community in order to embrace capoeira play. Data suggest capoeira can facilitate group playfulness, joviality, and laughter. Further, capoeiristas can enact and experience—some mode of—escapism via capoeira, whereby new place and pursuit can facilitate hedonistic diversion from the mundane. Capoeira appears to provide adventure and liberation into a relatively unburdened part of, or place in, social life. Corporeal and discursive boundary-empowerment can also be experienced by capoeiristas, fostering positive identity work in the wider world. Capoeira can be argued to facilitate mutuality (e.g. community experience and group work) and egoism (e.g. an individual's identity work) concurrently. This research suggests that modified capoeira for beginners can be beneficial for both the new capoeiristas themselves and for positive community action during and beyond class. 相似文献

Fears of an ‘obesity epidemic’ in New Zealand and elsewhere have led to a growing focus on children’s weight, diet and activities. The aim of this research project was to highlight children’s voices, stepping back from obesity interventions to explore how health and obesity discourses are taken up by young primary school children. Nine 6 and 7-year-olds took part in individual semi-structured interviews which involved play and craft activities to focus discussion. Discourse analysis was used to explore how children talked about bodies, health, fitness and fatness. Children primarily drew on a series of clear-cut dichotomies around good foods and bad foods, and being active, able and fit, as well as constructing health in relation to the body in two distinct ways: fat vs. thin, and big-and-strong vs. small-and-weak. These findings support previous research suggesting that children, from a young age, are taking up narrow corporeal constructions of health in relation to food and fitness ‘choices’, and additionally children assume that these constructions can be ‘read’ off the body. On the other hand, children were also often hesitant, and at times resisted or problematised these straight-forward constructions, occasionally drawing on alternate understandings, including notions of pleasure and practicality, moderation, and being happy and healthy. Future research could explore these ideas further, investigating how children and adults utilise alternate meanings to negotiate the complexity of bodies, health, fitness and fatness. 相似文献

采用文献资料法,根据马克思主义实践唯物论的主体哲学理论,分析主体性的哲学内涵,以及人的主体地位与体育存在的关系。体育主体性,是人主体性生成的一部分,是人本质实现的表现形式。人在合规律合目的的体育活动中,自觉感受生命力量、身体活力和运动位移,所带来的生命存在感与主动欲求,体育是人的类存在的主体象征。在体育主体性的理论奠基中,分析体育主体原则、主体素质和主体诉求的思想内涵。并进一步考察体育主体的内在性、外在性、能动性、受动性、参与性和观赏性的思维品性,希望在人本质的意义生成中,建立起体育与人主体性的哲学关怀。 相似文献
