Graphene Based Electrochemical Sensor for the Detection of Volatile Organic Compounds

Many household consumables contain volatile organic compounds(VOCs)as the active ingredient.Long term exposure to VOCs could cause various health problems,especially to the respiratory system.Graphene has attracted a lot of attention recently for its potential to be used as sensing material for VOCs.In this project we have constructed graphene/PVA composite based gas sensors for VOC detection.It was perceived that the polymer could introduce better selectivity to the sensor.Results suggest that the proposed sensor is highly sensitive to low molecular weight VOCs and that the manner in which the sensor respond to the vapour depends on the polarity or hydrophobicity of the vapour.     

Dynamics of Chinese nationalistic education in Hong Kong from 1945 to 2012

‘Chinese’ is an ambiguous term, depending on whether it is taken to describe a political, linguistic, or cultural entity. While the term has often been considered to represent a politically and culturally homogeneous national identity in recent decades, this article aims to challenge this notion by examining the characteristics and practices of nationalistic education in Hong Kong since 1945. It explores how national identity has been interpreted by different Chinese states over time through different educational policies and practices. Focusing on the evolution of nationalistic education in three phases, this article presents a detailed account and analyses different nationalist narratives over six decades. It describes how different political forces define themselves and come to terms with what are often dual or competing national identities. Historical examples illustrate the challenges in policies and practices of nationalistic education.     

Fred Wilson,PTSD, and Me: Reflections on the History Wars

Abstract Our relationships with our audiences have proved parlous. But if history is destined to be contested, where should museums be in that contest and how do we get there? Fred Wilson's Mining the Museum has turned out to be a path not taken; Enola Gay was a cautionary tale. But we should have these fights in museums, where the national narrative is blocked out and staged, because of how museums teach us, opening hidden windows on cloaked realities. Museums can start by becoming clearer about what they think they are doing when they make an exhibition. Exhibitions can have a profound effect on visitors at many levels but it doesn't happen very often. Is that because visitors seek another kind of experience from what we typically offer?     

New Approaches to Staff Recruitment in Higher Education

This paper describes briefly the academic tenure and its legislative terms in the UK, over the last twenty years. The author refers to the current wider situation/trends in the international higher education arena of two categories of academic staff – “established” staff (on permanent contract) and fixed‐term staff – and to how their levels of protection can have an impact on the overall health of the universities and their academic freedom.     

English in classrooms: only write down what you need to know: annotation for what?

The annotation of texts in the school English classroom is central to the curriculum, examination and the history of English as a school subject. In this paper we explore ‘the way it is done’ across two different classrooms. We focus on the relationship between official definitions of annotation offered by national policies and examination syllabuses and its actualization in particular classrooms. The article takes a multimodal approach: attending to all modes of representation and communication in the teaching of English including image, gesture, gaze and the spatial organization of the classroom.     

梅花拳"文场与武场"考辨

通过民族史学、体育史学、体育理论等学科原理,结合文献资料、综合分析法等,对梅花拳“文场与武场”的体育文化内容、体育文化特征及两者辩证关系进行系统研究。结果显示:梅花拳由文场与武场组成,文场敬祖师,研究拳理,有文化典藉世代相传。它集佛、道、儒三家学说和周易之理为一体,修心养性,炼神炼气,称为文功。武场主要进行武功锻炼,传授拳理等。以“练形以合外,练气以实内,由外及内,再由内而达外,内外一体。精气神合一,自成金刚不坏之体”为练武目的,最后上升到文功。文场是该拳派的领导核心,文场领导武场,文场是武场的高级阶段。

中国杂技艺术中的体育文化解读

运用艺术史学、体育史学、考古学等学科原理,结合献资料,对中国杂技艺术中的体育化进行分析解读。结果显示：东西方两个明中心几乎同时开始了一个百家争鸣的时代,尽管各种身体活动的体育实践各不相同,但对于人体的速度、力量、健美、灵巧等基本身体素质的追求和赞美的理念,各民族几乎是共同的。古人在翻腾跳跃,窜蹦跌打的生存劳动技能中产生了“小武术”、“大武术”、“对手顶”,“走钢丝”、斗虎、耍狮子等活动形式,它们既是杂技也是体育项目。从古至今,中国杂技艺术与体育化共生共荣,和谐发展。
