我国公民体育身份的社会认同及其提升路径研究

以社会学和政治学的视角分析体育身份在现代公民社会发展中发挥的独特作用。从体育消费、体育实践、体育运动方式、体育生活方式及体育参与群体方面考察社会公民的体育身份,围绕提升公民社会地位、社会参与、生活品味,提高公民文化素质及张扬公民个性展开阐述,突出我国社会公民的体育身份认同。我们应增强政府公共服务职能,扩大公民体育参与;提高市场供给能力,满足公民体育消费;树立科学价值取向,倡导体育生活方式;鼓励组建各种体育组织,完善公共服务体系。体育身份使体育在现代社会发展中越来越受到公民的认可,为推动公民社会的和谐发展提供理论依据。     

Concatenated Trellis Coding and CPM for DS/SSMA Communications in Rayleigh Fading Channel

本文在衰落信道下将级联网格编码调制（ＴＣＭ）和连续相位调制（ＣＰＭ）应用于直接序列扩频多址（ＤＳ／ＳＳＭＡ）系统中．作者分别采用了理论分析和数值模拟两种方法研究了级联ＴＣＭ／ＣＰＭＤＳ／ＳＳＭＡ系统的性能，结果表明在相同的条件下采用级联ＴＣＭ／ＣＰＭ编码调制方式的ＤＳ／ＳＳＭＡ系统的错误概率远小于采用单一ＴＣＭ或ＣＰＭ的ＤＳ／ＳＳＭＡ系统的错误概率．     

How can ICT contribute to the learning of foreign languages by pupils with SEN?

In this article Lynne Meiring and Nigel Norman focus on the notion of entitlement and the demands this has made on schools and teachers to cater for the needs of a wide range of pupils previously denied an experience of foreign languages. In order to enable all pupils to realise their potential, facilities and strategies have to be reviewed and developed to ensure that their learning experience is appropriate. This article focuses on the contribution that one such facility, namely information and communications technology (ICT), can make towards removing some of the barriers to learning experienced by some pupils, enabling them to realise some of the benefits of what has often been perceived as a particularly inaccessible curricular area. The authors examine how the generic capability of ICT can enhance and enable the learning of pupils with special educational needs (SEN), but do not purport to consider specifically the specialised technology required for certain manifestations of special need.

Studying parental involvement and university access and choice: An ‘interacting multiple capitals’ model

Capital‐embedded parental involvement in education is essential in enhancing university enrolment and maximising the educational potentials for equality and excellence. Previous studies in this field have mainly utilised Perna's ( 2000 , 2006 ) model, which defines parental involvement as social capital and identifies the additive influences of different types of capital (including social, economic and cultural capital) on university access and choice. Yet, little research to date theorises and disaggregates the interplay among various types of capital as well as the multiplicative capital effects on enrolment. This study addressed this gap. We proposed an ‘interacting multiple capitals’ (IMC) model and hypothesised that parental social capital could moderate the effects of cultural and economic capital on entry to university. To validate the model, a pilot survey was administered to 216 university students of Korean ethnicity in China and investigated the models of involvement adopted by Korean parents in the context of the increasing labour mobility of the Korean adult population. Moderated multiple regression analysis was employed and the results confirmed the hypothesis that capital effects upon university access and choice were multiplicative in nature, with social capital moderating the cultural capital influence on students’ educational aspirations. The study findings show that the interaction of various types of capital variables is sufficiently statistically significant to warrant future research and policy and practical discussion of how to promote parental involvement in university preparation and planning.     

Framing of transitional pedagogic practices in the sciences: enabling access

Educational literature shows that students from working-class backgrounds are significantly less likely to persist to completion in higher education than middle-class students. This paper draws theoretically and analytically on Bernstein’s ([1990. Class, Codes and Control, Volume IV: The Structuring of Pedagogic Discourse. London: Routledge; 2000. Pedagogy, Symbolic Control, and Identity: Theory, Research, Critique. Lanham: Rowman and Littlefield]) thesis that, through differential framing of pedagogic practices, the curriculum has capacity to accommodate all groups of students. Pedagogic practices in both a science foundation course and four first-year mainstream science courses in a higher education institution in the South African context are examined. Whilst the foundation course exhibits modalities that generally favour access, the mainstream courses have some modalities that appear to be constraining. It is argued from a social justice perspective that holistic curriculum transformations that better enable epistemic transitions are an urgent imperative, and that consideration of differential framing of pedagogic modalities offer a close-up empirical means of conceptualising such reforms.

In search of query patterns: A case study of a university OPAC

A transaction log analysis of the Nanyang Technological University (NTU) OPAC was conducted to identify query and search failure patterns with the goal of identifying areas of improvement for the system. One semester’s worth of OPAC transaction logs were obtained and from these, 641,991 queries were extracted and used for this work. Issues investigated included query length, frequency and type of search options and Boolean operators used as well as their relationships with search failure. Among other findings, results indicate that a majority of the queries were simple, with short query lengths and a low usage of Boolean operators. Failure analysis revealed that on average, users had an almost equal chance of obtaining no records or at least one record to a submitted query. We propose enhancements and suggest future areas of work to improve the users’ search experience with the NTU OPAC.     

The effect of use and access on citations

It has been shown (Lawrence, S. (2001). Online or invisible? Nature, 411, 521) that journal articles which have been posted without charge on the internet are more heavily cited than those which have not been. Using data from the NASA Astrophysics Data System (ads.harvard.edu) and from the ArXiv e-print archive at Cornell University (arXiv.org) we examine the causes of this effect.
