一种分布式系统中动态负载均衡策略

在分布式系统应用中采用动态负载平衡算法分配系统中的工作负载，能够显著地提高系统的性能。针对分布式系统中负载动态变化特性，提出了一种基于接收者主动的自索取动态负载均衡算法，通过负载数的实时变化反映系统中各节点的当前负载状况，通过空闲节点来转移超载节点的任务，使负载的分布更均匀，提高了整个系统资源的利用率及效率．

Do EFL Teachers ‘Critically’ Engage in Cultural Awareness? A Mixed-Method Investigation

ABSTRACT

This study explored 150 EFL teachers’ perceptions of critical cultural awareness (CCA) considering their teaching context, academic degree, and professional development programs. The participants all completed the CCA questionnaire, fifteen of whom also sat a semi-structured qualitative interview. Our findings showed, a) EFL teachers’ perceptions of CCA located at a medium level, b) the PhD participants showed significantly higher engagement in CCA than their BA and MA counterparts, c) private language institute teachers reported higher levels of CCA than their state-run school counterparts and d) local professional development programs did not emphasize culture teaching in general and CCA in particular.     

亚洲国家集体球类项目竞技实力的比较研究

运用文献法、数理统计法、比较分析法对亚洲各个国家或地区在第26、27、28届夏季奥运会集体球类项目上的竞技实力进行了比较研究,研究结果:亚洲各个国家或地区可以分成两大集团,第一集团包括中国、韩国、日本,第二集团包括中国台北、巴基斯坦、印度、伊拉克,集团之间的实力差距悬殊;在男子项目上,韩国、日本的实力高于其它国家或地区,女子项目的实力强弱顺序依次是中国、韩国、日本与中国台北;在各个项目上,竞技实力的强弱呈现出完全不同的变化,各个国家或地区都具有相对优势项目,但都不具备集团优势。     

Researching educational policy and change in ‘new times’: using critical discourse analysis

A number of writers have drawn attention to the increasing importance of language in social life in ‘new times’ and Fairclough has referred to ‘discourse driven’ social change. These conditions have led to an increase in the use of various forms of discourse analysis in policy analysis. This paper explores the possibilities of using Critical Discourse Analysis (CDA) in critical policy research in education, drawing on a larger research project which is investigating the equity implications of Education Queensland’s reform agenda. It is argued that, in the context of new times, CDA is of particular value in documenting multiple and competing discourses in policy texts, in highlighting marginalized and hybrid discourses, and in documenting discursive shifts in policy implementation processes. The last part of the paper discusses how such research might be used by policy activists inside and outside education department bureaucracies to further social democratic goals.     

Cognitive load of critical thinking strategies

Argument–counterargument integration (Nussbaum, 2008) refers to the process of evaluating, refuting, and synthesizing arguments on two sides of an issue when creating justification for an overall conclusion. This study compared the cognitive load of two critical thinking strategies related to argument–counterargument integration: (a) constructing design claims that minimize disadvantages of an alternative, and (b) weighing refutations (which weaken an argument by arguing that there are more important values at stake). College students (N = 285) first completed the Need for Cognition (NFC) scale and were then presented with materials summarizing arguments and counterarguments on the topic of grading class participation. Participants completed a small, integrative essay justifying a stand on the issue, and completed the Mental Effort Rating Scale (Paas, 1992). Participants who generated complex weighing refutations reported more mental effort than those constructing complex design claims (and the control group), with a stronger relationship with those high in NFC. The need to coordinate disparate elements in working memory may explain the higher load associated with constructing weighing refutations. Students may need more (and different types of) scaffolding in using this strategy than when constructing a design claim, which is a more sequential process.

Data assemblages,sentient schools and digitised health and physical education (response to Gard)

Michael Gard raises some important issues in his opinion piece on digitised health and physical education (HPE) in the school setting. His piece represents the beginning of a more critical approach to the instrumental and solutionist perspectives that are currently offered on digitised HPE. Few commentators in education, health promotion or sports studies have begun to realise the extent to which digital data surveillance and analytics are now encroaching into many social institutions and settings and the ways in which actors and agencies in the digital knowledge economy are appropriating these data. Identifying what is happening and the implications for the concepts of selfhood, body and social relations, not to mention the more specific issues of privacy and the commercialisation and exploitation of personal data, requires much greater attention than these issues have previously received in the critical social research literature. While Gard has begun to do this in his article, there is much more to discuss. In this response, I present some discussion that seeks to provide a complementary commentary on the broader context in which digitised HPE is developing and manifesting. Whether or not one takes a position that is techno-utopian, dystopian or somewhere in between, I would argue that to fully understand the social, cultural and political resonances of digitised HPE, such contextualising is vital.     

关于伪距差分和载波相位差分的精度比较研究

伪距差分和载波相位差分是差分GPS的两大定位技术,在各领域都有广泛的应用。本文首先介绍GPS的定位原理及其误差分析,然后介绍伪距差分原理和载波相位差分原理,最后结合实例,通过点位漂移量和点位中误差,证实载波相位差分定位精度高于伪距差分定位的精度。     

房地产开发土地增值收益分配及相关利益主体行为分析

房地产开发为我国土地增值过程中由于供不应求、投资开发、用途转变等原因产生增值。以土地租税费制度为依据的我国现行土地增值收益分配模式已然不能满足相关利益主体对土地增值收益的需要。中央政府、地方政府、开发商、商业银行、投资者等在不同层面、不同程度地参与了土地增值收益的分配,在其相互之间行为博弈的情况下,形成了土地增值收益的分配格局,从而刺激了他们对土地增值收益的非理性追逐。因此,通过对我国现行土地租税费制度的阐述和对在房地产开发过程中相关利益主体的行为分析,重构均衡各主体之间利益的土地增值收益分配模式。
