诺亚与埃克斯坦比较教育功能理论述评

诺亚和埃克斯坦的比较教育功能理论是在实证主义研究范式的影响下逐渐形成的,并在长期的教育科研实践中走向成熟。他们对比较教育功能的阐述可以集中概括为教育信息的普及功能、教育认识的标准功能、教育规划的决策功能以及教育规律的推导功能四个方面,并呈现出逐级递进的态势,在构建与完善比较教育科学量化研究方法和勾勒比较教育的发展框架上发挥了重要的作用。诺亚与埃克斯坦的比较教育功能理论体系以鲜明的实践导向性为比较教育与教育改革的充分整合提供了科学的参照标准。

The gown and the korowai: Māori doctoral students and the spatial organisation of academic knowledge

This paper draws on 38 student interviews carried out in the course of the team research project ‘Teaching and Learning in the Supervision of Māori Doctoral Students’. Māori doctoral thesis work takes place in the intersections between the Māori (tribal) world of identifications and obligations, the organisational and epistemological configurations of academia and the bureaucratic requirements of funding or employing bureaucracies. To explore how students accommodate cultural, academic and bureaucratic demands, we develop analytical tools combining three intellectual traditions: Māori educational theory, Bernstein’s sociology of the academy and Lefebvre’s conceptual trilogy of perceived, conceived and lived space. The paper falls into six parts. Section 1 is an overview of the research and is followed in Section 2 by identification of intersecting ‘locations’ in which Māori students’ theses are produced. In Section 3, Henri Lefebvre’s spatial analysis highlights connections between students’ multiple allegiances and affinities. Drawing on Bernstein, Section 4 relates the theses to the organisation of ‘Western’ academic disciplines. Section 5 addresses students’ cultural locations beyond the reach of ‘Western’ disciplines. We conclude with implications for supervision.     

The social structure of entrepreneurship as a scientific field

Entrepreneurship as a scientific field has grown significantly, irrespective of the measures used. In this article we raise the question: How can we understand the evolution and success of entrepreneurship as a scholarly field? In particular, we focus on the social structure of entrepreneurship scholars to explain (1) how they are becoming integrated into larger scholarly communities and (2) how they differ from the way scholars integrate within the field of innovation studies. Based on a unique database and responses from 870 entrepreneurship scholars, we demonstrate that entrepreneurship can be regarded as a phenomenon-driven field bound together by a shared communication system and social interaction rather than strong theoretical influences, i.e., a social scholarly community. We identify two broader social communities; one embedded in entrepreneurship conferences that includes a rather eclectic group of entrepreneurship scholars, and another related to entrepreneurship journals and entrepreneurship economics, characterized by a stronger domain orientation. In contrast, scholars in innovation studies tend to be more theory-driven and are bound together by their disciplinary and theoretical background, i.e., an intellectual scholarly community.     

中国与世界优秀女子足球队进攻能力比较分析

采用录像观察统计法、数理统计法对德国、巴西、美国、挪威及中国女足的进攻技术、战术进行了初步探讨,研究表明:前四名球队射门、定位球进攻、争顶球和传中以及运球过人等能力均较中国队表现突出,其主要原因与中国队整体进攻技战术打法不合理密切相关.     

中国式“不差钱”与中国式“钱荒”之悖论

最近中国式"钱荒"和前期中国式"不差钱"形成了强烈反差,并引发了全世界的关注。文章分析了对于"钱荒"目前盛行的5种假说:国际阴谋说、季节波动说、央行自制说、影子银行说和地方债务说,并从效度、信度和认知度3个维度对各种诱因进行测度评估,然后分析了中国与西方政治体制和财政体制的不同,预测了各种调控手段对未来中国经济可能造成的影响,最后得出央行应借机降低存款准备金率的建议!

一种快速的QAM信号半盲混合均衡算法研究

针对传输正交幅度调制(QAM)信号的多输入多输出(MIMO)无线通信系统中的信号间干扰问题,提出了恒模算法(CMA)和软决策(SDD)算法相结合的混合算法。该方法代价函数结构简单,精确地利用了已知信息,使得均衡后信号具有良好的误码率性能。本文采用共轭梯度法进行优化,与现在常用的梯度类算法相比较,具有快速收敛的特性。最后分别通过信道最大扭曲和收敛速度分析了该算法的可靠性和有效性,且通过计算机仿真证明了该算法的良好性能。
