Hydrogenation properties of mechanically milled Mg2Nio.8Cr0.2-CoO/Al2O3 composites

Mg2Ni0.8Cr0.2-x wt.% CoO/Al2O3 (x=0.5, 1, 2 and 3) composites were prepared by mechanically milling sintered Mg2Ni0.8Cr0.2 alloy and CoO/Al2O3 compound for 45 h. The addition of CoO/Al2O3 compound resulted in the good kinetics properties of hydriding/dehydriding reaction of the composites. The composite with 1.0 wt.% CoO/Al2O3 catalyst could reach the maximum hydrogen absorption capacity (2.9 wt.%) within 5 min at 393 K under H2 pressure of 4 MPa, and can desorb rapidly at 493 K. The decomposition and synthesis of hydrogen molecule on Mg2Ni0.8Cr0.2 alloy surface was promoted by addition of CoO/Al2O3 catalyst. In addition, the formation of metallic Ni particles, strain and defects during the ball milling process also resulted in the improved hydrogenation performance of Mg2Ni-based alloys.     

艺术起源学说辨析

考察现今众多的艺术起源学说,虽然各自都有其自圆其说的理论依据,但却都经不起 其他理论的反证,这说明了艺术的起源是多种因素共同作用的结果。由于人不仅具有社会属性,而 且首先具有自然属性,因此研究艺术的起源需从这两方面综合进行。而现有的艺术起源学说都试 图从某一个侧面来对艺术起源问题进行阐释,这势必会将问题简单化。

‘Playing with space’: a conceptual basis for investigating active sport tourism practices

ABSTRACT

This paper proposes a conceptual tool, the expression ‘playing with space’, for the analysis of active sport tourism as a meaningful social practice. The expression issues from practice theories and pragmatic understandings of space, which emphasize the processual and contextual dimensions of human action and seek to seize altogether the corporealities and shared conceptions that constitute action. On such views, sport tourists are considered as reflexive and embodied beings, enjoying sensations, mobilities and places, and constantly (re)making sense of their own practices. I argue that the notion of ‘play’ allows for a comprehensive understanding of the ways active sport tourists engage with space, where space is viewed as an object or material for this play. Three major dimensions of active sport tourism are then identified: a set of playful and game-like practices with global space resulting in shared imaginaries and large-scale mobilities; a kinaesthetic play, based on freedom and sensations and deeply engaged in the materiality of the places and the omnipresent media practices that support the other dimensions of play while being fully integrated into the experience of sport tourism. This conceptual framework is a way to better understand the motives and practices of sport tourists; it is also a way to underline wider trends of contemporary leisure cultures: such cultures are increasingly integrated into the daily spheres of activity, increasingly playful and increasingly mediatized.     

广西博白客家采茶戏戏班调查

广西博白客家采茶戏自明末形成以来,已经有近400年的历史。古老的民间戏班传统一直延续到今天,但是在不同的历史时期其生存状态有很大差别。作者通过实地调查发现,民间戏班办班经费都是班主或者其他人自筹,基本的生存方式是通过营业性演出获得报酬,维持基本需要。采茶戏班演出剧目主要以受老年人欢迎的古装采茶戏为主,并有相对固定的戏路机制。采茶戏班在其表演的过程当中经常伴随着一系列的仪式,这些仪式对于戏班和请戏人都具有特别的意义。作者最后依据实地调查资料提出,要振兴桂南采茶戏,应从以下两个方面入手：政府应加强对采茶戏班的管理与引导;要充分抓住当前“非物质文化遗产”保护的大好时机,加大保护宣传力度。

A dynamic learning concept in early years’ education: a possible way to prevent schoolification

In early childhood education and care, Nordic social pedagogy approach is challenged by a learning orientation that often results in unproductive ‘either/or’ thinking. Therefore, based on the two approaches and by analysing several dimensions of Froebel’s ideas and prevailing social-historical activity (play) theory, the author deduces four generally accepted play criteria that form the basis for the construction of a dynamic and play-based learning concept that has the three following cornerstones as focal points: (1) learning happens in activities where the child is an active participant and interacts and communicates with other people; (2) meaningful activities pave the way for children’s learning; these are activities where the child’s motive aligns with the goal of the activity; and (3) learning is seen as a productive and creative activity characterised by imagination.
