Human dignity within teacher education: A matter of individualism, competitiveness, and strategic rationality

Human dignity is a grand concept that is assumed to play an important role in education. However, no widely accepted universal definition of human dignity exists. The aim of this study was to examine the Discourse of Human Dignity within teacher education, especially with respect to how Swedish teacher educators make meaning of the concept of human dignity. Findings show that four subdiscourses are involved in the Discourse of Human Dignity within teacher education. These discursive constructions are influences by outcomes of, for example, life-science research, and British and/or American media discourses.     

Face-to-face versus computer-mediated discussion of teaching cases: Impacts on preservice teachers’ engagement, critical analyses, and self-efficacy

Two frequently-used discussion protocols were investigated as part of a program to implement teaching cases in undergraduate educational psychology classes designed for preservice teachers. One protocol involved synchronous face-to-face (FTF) discussion of teaching cases, which occurred in class after students had individually completed written case analyses as homework outside of class. The other was asynchronous computer-mediated (CM) discussion taking place outside of class, simultaneous to students’ completion of their written case analyses. Six class offerings of an undergraduate child development course taught by two instructors (three classes by each instructor) were randomly assigned within instructor in a quasi-experimental design to one of the three discussion conditions: FTF, CM, or no discussion of the cases across the semester. Findings indicated that both CM and FTF discussion conditions were associated with positive outcomes relative to the control condition. Both CM and FTF discussion related to higher cognitive–affective engagement with the cases than the control condition; and the CM discussion condition was associated with higher cognitive–affective engagement than FTF discussion. In contrast, FTF discussion, but not CM discussion, was associated with higher-than-control-condition case analysis ability at the end of the semester. Potential explanations for these findings and directions for future research are discussed.     

来自“局内人”的真实讲述——读阿里瓦萨《文化传承与民族教育田野调查——三十三位凉山彝人访谈录》

局内与局外,是人类学家文化观察和田野讲述的不同视角。阿里瓦萨《文化传承与民族教育田野调查——三十三位凉山彝人访谈录》,是其博士学位论文田野调查访谈录。该访谈录表面的堆砌和杂陈,是作者就彝族家支、文化传承与民族教育主题而采用一个灵活的书写策略,而其中鲜活、独到的田野话语,确是来自凉山彝族民间真实的讲述。     

利用杜邦分析法进行财务综合分析

单独任何一类财务指标,都不能全面评价企业财务状况和经营成果,只有系统、综合地分析各种财务指标,才能对企业的财务状况作出全面、合理、正确的评价。通过财务综合分析法可以评价企业的财务状况和经营成果,杜邦分析法就是其中的一种,文章根据杜邦分析法的优缺点对其进行改进,并用改进的方法对保利房地产企业进行财务综合分析。

Real time search on the web: Queries,topics, and economic value

Real time search is an increasingly important area of information seeking on the Web. In this research, we analyze 1,005,296 user interactions with a real time search engine over a 190 day period. Using query log analysis, we investigate searching behavior, categorize search topics, and measure the economic value of this real time search stream. We examine aggregate usage of the search engine, including number of users, queries, and terms. We then classify queries into subject categories using the Google Directory topical hierarchy. We next estimate the economic value of the real time search traffic using the Google AdWords keyword advertising platform. Results shows that 30% of the queries were unique (used only once in the entire dataset), which is low compared to traditional Web searching. Also, 60% of the search traffic comes from the search engine’s application program interface, indicating that real time search is heavily leveraged by other applications. There are many repeated queries over time via these application program interfaces, perhaps indicating both long term interest in a topic and the polling nature of real time queries. Concerning search topics, the most used terms dealt with technology, entertainment, and politics, reflecting both the temporal nature of the queries and, perhaps, an early adopter user-based. However, 36% of the queries indicate some geographical affinity, pointing to a location-based aspect to real time search. In terms of economic value, we calculate this real time search stream to be worth approximately US $33,000,000 (US $33 M) on the online advertising market at the time of the study. We discuss the implications for search engines and content providers as real time content increasingly enters the main stream as an information source.     

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

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.

基于GIS的区域关键性生态用地空间结构识别方法探讨

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。
