Contemporary discourses in Information Systems Research: Methodological inclusiveness in a sample of Information Systems Journals     

Alberto Paucar-Caceres  Gillian Wright 《International Journal of Information Management》2011,31(6):593-598

We propose a framework to reflect on the development of four information systems (IS) paradigms, arguing that this field has followed a similar path to that of Management Sciences (MS). The framework comprises four IS paradigms/discourses: (1) positivist/normative; (2) soft/interpretive; (3) critical/pluralistic; and (4) constructivist/2nd order cybernetics. The paper characterizes these approaches to IS by using four key terms: System; Organisation; Management and Information, exploring the way these concepts are perceived through the lens of the four paradigms. The paper reports on the nature of current IS trends, from an initial survey of six top IS journals identifying articles adhering to the interpretive, critical and constructivist paradigms published between 1999 and 2009. Results indicate that IS is moving towards research practice in which interpretive, critical and constructivist discourses are utilised. Implications of the proposed framework and publication trends, together with some points for further research, are offered.  相似文献

基于GIS的区域关键性生态用地空间结构识别方法探讨   总被引：10，自引：3，他引：7  

谢花林  李秀彬 《资源科学》2011,33(1):112-119

随着我国城镇化进程的加速,如何协调好城镇建设与地域生态系统的关系成为当前规划界的热点问题之一。本文基于GIS技术,从水资源安全、生物多样性保护、灾害规避与防护和自然游憩等4个方面,构建了空间尺度上的生态用地重要性综合指数和区域关键性生态用地空间结构识别方法,并进行了京津冀地区的实例研究。结果表明,京津冀地区核心型生态用地的面积为54943.87km2,占全区总面积的1/4,分布在西北部山区,主要是区域的河流水系、湿地、自然保护区、森林公园和风景名胜区的核心区,是维护区域生态安全的底线生态用地。识别结果能较好地反映关键性生态用地维护区域水、生物、灾害防护和游憩安全的空间特征。该识别方法将有利于指导我国土地的生态管理,开展生态保育和生态建设,维护区域生态系统健康与安全。  相似文献

Critical Discourse Analysis： A Theoretical Framework for Analyzing Mathematics Teaching in Multilingual Classrooms？     

Nancy Chitera 《美中教育评论》2014,(12):861-872

The purpose of this article is to develop a framework that can be used to describe and explain how mathematics teachers construct a multilingual classroom and the discourse practices being produced in a mathematics classroom. It conceptualizes the discourse practices used by mathematics teacher educators as they prepare student teachers to teach mathematics. The framework developed here is shaped by Critical Discourse Analysis （CDA） drawn from Fairclough. This provides the theoretical and conceptual tools to examine the discourse practices of mathematics teacher educators and how the）＇ make available these discourse practices for student teachers to draw on. In broad terms, this article examines the discourse practices of the mathematics teacher educators and how they support the student teachers develop discourse practices relevant for teaching and learning school mathematics in multilingual classrooms. This article is broken down into several sections. The first section discusses what it means for student teachers to develop discourse practices for mathematics teaching. The second section provides an introduction to CDA, followed by its origins, key terms, and elements of Fairclough＇s CDA. Thereafter, the author outlines the strategies involved in doing CDA. The last section discusses why CDA is relevant to the mathematics classroom.  相似文献

文学批评中的个人情绪化与批判指向的偏错——论金庸武侠小说的批判中所存在的问题     

惠帅 《宁波广播电视大学学报》2014,12(3):17-20

大约在上个世纪末起,中国掀起了一波涉及金庸、武侠小说、金庸热及金庸武侠小说等现象的批评热潮,而在相当多的有关金庸武侠小说的批判中却存在着个人情绪化突出,批判的矛头指向偏错等问题.许多知名人士或学者在试图去批判金庸武侠小说时实质上却是在批判武侠小说,批判金庸,批判与金庸武侠小说有关的各种社会现象.他们所要批判的对象与其实际批判的矛头不相对应,似乎是南辕北辙、“声东击西”.  相似文献
