Educational psychology service contribution to community cohesion: an appreciative inquiry

ABSTRACT

The United Nations Convention on the Rights of a Child (UNCRC) calls for education to prepare children for ‘ … responsible life in a free society, in the spirit of understanding, peace, tolerance, equality of sexes, and friendship among all peoples, ethnic, national and religious groups and persons of indigenous origin’. The current study examines the potential role of Educational Psychologists (EPs) in addressing the UNCRC call to promote community cohesion through their work in schools. Through an Appreciative Inquiry cycle EPs considered facilitators of and barriers to working with communities. Facilitators included EP practices, skills and knowledge and seeing schools as communities in themselves. Barriers included public service funding and aspects of service delivery. A multi-level approach to promoting community cohesion is put forward, including acknowledgement of the context within which the work takes place as well as positing a continuum of community cohesion to community conflict.     

Identity and inter religious understanding in Jewish schools in England

This article sets up a dialogue between auto-referential (looking to self) and allo-referential (looking to the other) approaches to religious difference and applies these to education for inter religious understanding in Jewish schools. It begins by arguing that the multiculturalism of the 1980s and 1990s set up a duality of self and other, with the responsibility for looking to ‘the other’ (allo-reference) resting largely on the majority community and the licence to look to self (auto-reference) being given to minority communities. Within the Jewish community, multiculturalism supported and legitimated the development of an inward-looking Jewish identity-based education. This was challenged in the 2000s however by the new outward-looking emphases of the community cohesion agenda, and so Jewish schools have had to negotiate a place for themselves between auto- and allo-reference. Brief case studies illustrate contrasting ways in which two schools have positioned themselves in relation to these two poles. In School A, the imperative towards ‘the other’ attempts an openness to ‘the other’ in ‘the other’s’ own terms, whereas in School B the same imperative towards ‘the other’ is framed within the auto-referential framework of being and doing Jewish.     

英语写作中词汇衔接手段的运用

通过分析具体实例,从过渡词、重复、照应等三个方面论述了提高段落写作连贯性的方法,并指出词汇衔接手段的有效使用,不仅可以使句子贯通自然,还能使句式多样化、错落有致,增强文章的审美效果。     

代数方程之伽罗瓦理论的历史发展--从拉格朗日到戴德金

伽罗瓦通过引入正规子群得到代数方程根式可解的充要条件,建立了伽罗瓦理论。在这一理论的发展中,戴德金做出了重要贡献。通过对原始文献的研究,从历史的角度,在拉格朗日路线图的基础上,以正规子群为线索,勾勒出一条代数方程之伽罗瓦理论的由拉格朗日到戴德金的逻辑链。对于可解方程,伽罗瓦的工作仅说明了正规子群的存在性,戴德金在拉格朗日和伽罗瓦的基础上,给出了一个获得方程的群的正规子群的构造性方法。对这一发展的研究不仅可以呈现伽罗瓦理论早期发展的思想线索,而且有助于更好地理解伽罗瓦理论及其历史发展进程。     

世界主要国家的国家凝聚力评价研究

文章以构成国家凝聚力的五大支撑要素,即物质、精神、文化、政治、安全为基础,构建了国家凝聚力指标体系。开发了基于三阶段模型的国家凝聚力评价方法,对全球45个样本国家的国家凝聚力状况进行定量评估和分析。对联合国五大常任理事国、金砖5国的国家凝聚力进行了综合比较分析。研究表明,中国国家凝聚力在45个国家中排第14位,处于第一梯队(15个国家)的后列,其比较优势要素是精神凝聚力,比较劣势要素是政治凝聚力。     

基于冗余异质性的创新网络治理研究

技术创新网络治理是维持网络稳定及促进网络中知识信息流畅运行的核心问题,但现有文献在研究其异质性构成及结构优化方面相对缺乏。从网络成员异质性构成所导致的问题出发,将创新网络划分为核心企业层级与非核心企业层级,运用多元回归分析方法研究层级内异质性构成与层级间同质性构成的冗余异质性结构对网络均质、脆弱及分裂的抑制作用及对网络创新绩效的影响。结果表明,冗余异质性结构的建立与网络成员均质化、脆弱性及网络分裂断层负相关;网络成员凝聚力在冗余异质性与网络创新绩效间起中介作用。     

英语语篇标记分析

语篇标记作为语义性连接纽带的有形衔接是连贯的外在形式，起着表明说话者或作者的态度、意图或倾向等的作用。文章主要论述语篇标记的类别、语法形式、语文特征及逻辑语文关系等内容。     

语篇意识对翻译教学的指导作用

随着语言学理论在翻译领域的推广应用，话语(或语篇)作为翻译的基本单位已经成为翻译教学的有效策略。本文展示了在翻译理论领域语篇研究的基本概况，并通过对一则八级英译汉试题译文的分析，说明了用语篇意识指导翻译实践的有效性，最后总结了将语篇意识应用于翻译教学的具体操作方法。     

英汉双语话语组合方式探析

话语分析主要研究大于句子的话语或篇章。它突破了主流语言学以句子为语言研究的最高形式,这就大大拓宽了语言的研究视野。话语分析是进行动态的分析,而理论语言学是进行静态的语言描写;前者是博采式的研究(in-widthapproach),后者是深探式的研究(in-depthapproach),二者呈现出互补的关系。
