知识组织系统(Knowledge Organization Systems/Services,简称KOS),是对各种对人类知识结构进行表达和有组织的阐述的语义工具(Semantic tools)的统称,包括分类法、叙词表、语义网络,以及更泛指的情报检索语言、标引语言。过去几十年中,许多编制这些工具的方法应运而生,对知识组织系统类型和功能的探索也发展到一定阶段,特别是在联机时代,用于标引和检索的知识组织系统的发  相似文献

In 2001, the Regenstrief Institute for Health Care and the Indiana University School of Medicine (IUSM) began an IAIMS planning effort to create a vision and a tactical plan for the first Integrated Advanced Information Management Systems (IAIMS) implementation to cross a large area and include unaffiliated institutions. A number of elements made this planning effort unique. Among these elements were the existence of a network infrastructure that supported the Indianapolis Network for Patient Care, the existence of a mature medical informatics program at the Regenstrief Institute, and the existence of a wide-area knowledge network fostered by the IUSM libraries. However, the leadership for a strong information technology role in the IUSM that could promote collaboration in support of education and research across the diverse Indianapolis hospital systems had been lacking. By bringing together various groups, each with a commitment to improve health care quality and public health across the Indianapolis metropolitan area, regardless of individual institutional affiliation, the strategic directions for I3-Indianapolis IAIMS Initiative have been defined and the foundations for a third generation IAIMS construct have been laid in Indianapolis, Indiana.  相似文献

As a participating student in the Border Studies Program in the fall semester of 2000, the author did a field study working as a volunteer at El Centro de los Trabajadores Agrvcolas Fronterizos (The Border Agricultural Workers' Center, or CTAF). In this ethnography, he intertwines the exploration of several different relationships. He examines the relationship between the current struggles of farm workers in the U.S. and the movement led by Cesar Chavez in the 1970s; and the relationship between the ''periphery'' and the ''center.'' He also reflects upon his own position within the progressive movement, given the social privilege that adheres to him by virtue of race, class, and sex.  相似文献

Staff development practices that successfully implemented long‐term applications of cluster grouping in two districts are analyzed, compared, and reviewed. Parallel practices and differences are discussed concerning program beginning, implementation, and maintenance. Conclusions are drawn and six steps for use and consideration by others engaged in gifted program development and implementation are suggested. These steps are: (1) conversations, (2) research, (3) choosing a course of action, (4) implementation, (5) supporting the new program initiative, and (6) maintenance and growth.  相似文献

We contrast the current science education reform effort with the reforms of the 1960s and suggest how the current effort could be enhanced. We identify insights from recent research that we believe can inform the reform process, in particular, to reach all science students and also impart a cohesive view of science. We propose an alternative models view of scientific explanation and show how this view would contribute to reforms of (1) course goals, (2) social aspects of science learning, (3) instructional practices, and (4) roles for technology.This paper summarizes discussions and debates that the authors have had over the last few years. The dialogue stems, in part, from our joint participation in the American Educational Research Association Special Interest Group on Education in Science and Technology (AERA SIG:EST) leadership. This paper communicates the spirit of our thinking and does not necessarily reflect the view of SIG:EST, or any other organization.We gratefully acknowledge the support of National Science Foundation Grant MDR-9253462 in work related to this paper. We appreciate helpful comments from Eileen Lewis and the Computer as Learning Partner group.This material is based upon research supported by the National Science Foundation under grant RED-9155744.

Distance education planners face two basic, yet difficult decisions: which students should be targeted and which programs should be offered? This paper reports the process and results of the planning committee of a consortium of engineering schools in the United States that was tasked with these very decisions. A market research study measured the program preferences of potential students. Three program characteristics (course type, delivery method, and time availability) were examined. The results show there is no ‘average’ student and no single program will satisfy all the needs of the student population. Rather, the committee must choose one or more segments based on the program preferences of the students and the resources required to provide the programs.  相似文献

Drawing on the notion of cutting together-apart introduced by Karen Barad and combining it with Lefebvre’s notion of a flaneur (f. flâneuse) who moves between temporal, spatial and political relationships, this article performs a collaboration mediated by social media, namely blogging and tweeting. It draws on the notion of history, space, and social relationships to describe how two women met online. This collaboration as inquiry is about working together despite our differences – finding places to meet rather than diverge, and to dialogue rather than debate. Through a duo-ethnography of how this relationship worked and did not work, notions about how the digital world can act as a mediator for academic work are explored.  相似文献
