公平、效率、自由选择,是现代高校招生考试制度的基本理念。澳大利亚"多元与统一"、"灵活与适性"特征兼具的高校招生考试制度体系,既体现了教育考试的公平价值取向,又为各类高校有效甄别学生入学提供了保障。而澳大利亚高校招生考试中学生自由选择权以及高校招生自主权的实现,反映了非资源约束条件下高校招生制度的改革方向。 相似文献

This study examines the influence of sociocultural factors on the level of “Internet connectedness.” The Internet Connectedness Index (ICI), composed of five items, is modified and applied to measure disparities in the ways in which people use the Internet. With a dataset of 384 randomly selected telephone survey respondents, the ICI is regressed on various social indicators. The result indicates that technological environments, social environments, and the scope and intensity of Internet-related goals significantly influence individuals' Internet connectedness. This finding highlights that even after people gain access to the Internet, the ways they incorporate the Internet into their everyday lives differ, and that the differences reflect disparities in the multiple dimensions of the social context in which individuals are situated. 相似文献

AbstractThis study aims to identify, collect and critical review the research literature on Multilingual Digital Libraries in English language from 1997 to 2012.Design/methodology/approach: The present literature review has followed the rules of systematic review. In particular, the identified relevant papers were categorized based on their expressed aim on two core themes, that of system-centered and user-centered studies. The assigned papers were further analyzed and six sub-themes emerged for the system-centered studies and four for the user-centered studies. Additional categorization was also provided according to type of publication.Findings: The literature concerning Multilingual Digital Libraries is vast and mainly focuses on two aspects the “System” and the “Users”. The majority of papers tried to meet the challenges raised for enabling multilingual information retrieval in Digital Libraries. Unfortunately, these efforts undertaken by a small number of researchers or research groups apparently working in isolation and therefore resulting in the development of numerous different tools and techniques. Relatively few studies have focused on the user and aimed to explore users' behavior and expectations when interacting with Multilingual Digital Libraries. As a result, further research is needed to reach to some tangible and usable findings.Originality/value: This literature review captures the diversity of the research conducted regarding multilingual information access and retrieval in Digital Libraries. It organizes the vast literature in comprehensive themes and sub-themes enabling easy access to specific information.Limitations: This study reviews only papers in English due to language restrictions from 1997 to 2012. 相似文献

ABSTRACT A data warehouse, developed for United States Department of Energy/National Nuclear Security Administration (USDOE/NNSA) Pantex Plant in a multi-department collaboration, brings data from disparate datasets and spatial information about the site together into a single database accessible through an intranet web page or ArcGIS software. The web page directs queries of buildings, facilities, and areas through a Geographic Information System (GIS) viewer that displays spatial site information and chemical hazards data. The Spatial Database Engine (ArcSDE) provides the vehicle for linking mainframe datasets, downloaded daily, to current spatial information about buildings and facilities that store chemicals of potential concern to firefighters and other emergency responders. The system is available to the plant's shift supervisors and individual GIS users throughout the department. 相似文献

This article is a glossary of terms one finds in open source integrated library systems (ILSs). The focus of this glossary is on the two major open source ILSs—Evergreen and Koha. These are being used in an increasing number of U.S. and Canadian public libraries as well as other types of libraries. The glossary is an introduction to the terms that those working with these open source library systems use on a day-to-day basis, with links to sources with more information for those new to open source projects. 相似文献

This article frames the public library and its system of organization as rhetorical tools. By providing an historic overview of libraries and their formation, the author recognizes the severed connection between library systems and the field of rhetoric, specifically the rhetorical canon of memoria. He seeks to reconnect memoria to the public library by recognizing the place-based nature of both classical memoria and library classification systems. The implications, he contends, run deep in libraries as seemingly neutral entities shape collective memory and education. Finally, the author provides a section that focuses on how digital-age libraries could be shaped, maintained, and managed in a way that recognizes memory as a rhetorical tool that aids in knowledge formation. 相似文献

Accumulating evidence suggests children enrolled in full-time child care often display afternoon elevations of the hormone cortisol, which is an indicator of stress. Recent advances in immunoassays allow for measurement of activity in the hypothalamic–pituitary–adrenal axis and the autonomic sympathetic nervous system from saliva, and measurement of both systems provides a more complete understanding of activity in the stress response system. This study is the first to examine both cortisol and alpha-amylase in children attending child care and focuses on the influences of specific indicators of classroom process quality. A diverse sample of 63 preschool children nested in 14 classrooms of varying quality participated in this study; child salivary cortisol and alpha-amylase were collected at six times over 2 days. Results indicate that children in classrooms with higher Emotional Support displayed a greater decline in cortisol from morning to afternoon. Further, children in classrooms with higher Emotional Support exhibited lower total alpha-amylase output while attending child care. Implications for professional development for early childhood teachers and measurement of classroom quality are discussed. 相似文献
