A basic challenge of the Weinberg Report addressed the question of information overload. The Weinberg Panel was extremely
concerned with the proliferation of scientific literature and the specific issue of how to sift through reams of data to find
the “gems” of wisdom, or that which is truly new and useful. In the early 1960s when the report was being written, computers
were not part of the information access and retrieval infrastructure. Writing twenty-five years later, in 1988, Dr. Weinberg
recognized that the panel had not adequately taken into account the impact of the computer and the growth of the information
industry. Today we have a new world of microcomputers and networked information which is fundamentally shifting the paradigm
of scientific communication. We have new capabilities, including electronic publishing, visualization techniques, even virtual
reality. Without getting into a great debate about the definition of “grey literature,” the main characteristics have traditionally
been described as: rapid publication, wariable formats, no public peer review, and no commercial source of general availability.
With networked information and multi-media technology, the new world of grey literature is emerging with an interesting set
of new and revived challenges. This article looks at the most interesting characteristics, and based on them, presents the
thesis that in the 1990s we are facing a new generation of “grey literature”. 相似文献

In 2010, the Association for the Advancement of Sustainability in Higher Education released, “Sustainability curriculum in higher education: A call to action,” encouraging infusion of sustainability topics into universities' teaching and research. Since then, academic programs and research related to social, economic, and environmental sustainability have enriched university curricula. An exploratory study was conducted to determine the position and engagements of academic libraries and information science schools in their contributions to scholarly sustainability activities and curricular initiatives. This article presents the results of the study which reveals a number of engagements by library professionals in the areas of sustainability, such as increasing open access to research, building sustainability-related collections and research guides, and incorporating sustainability content into information literacy. While academic libraries and information science schools are engaged in a broad spectrum of initiatives that support their institutions' sustainability research and curricular functions, this study indicates that such activities require a more targeted approach. 相似文献

Teaching faculty in ten entry-level professional fields reported varying amounts of time devoted to teaching, research, consulting, and professional practice but did not differ in time devoted to administration. The faculty member's own role view was most closely related to time use, but for time spent in teaching and research, faculty age and institutional type (but not gender) were also significant predictors. Even after several general demographic characteristics and environmental variables that potentially differentiate professional from discipline-based faculty are taken into account, different professional fields may be characterized by group climates which influence or reinforce certain faculty roles. 相似文献

Exploiting aspectual features and connecting words for summarization-inspired temporal-relation extraction 总被引:2,自引:0,他引:2
This paper presents a model that incorporates contemporary theories of tense and aspect and develops a new framework for extracting temporal relations between two sentence-internal events, given their tense, aspect, and a temporal connecting word relating the two events. A linguistic constraint on event combination has been implemented to detect incorrect parser analyses and potentially apply syntactic reanalysis or semantic reinterpretation—in preparation for subsequent processing for multi-document summarization. An important contribution of this work is the extension of two different existing theoretical frameworks—Hornstein’s 1990 theory of tense analysis and Allen’s 1984 theory on event ordering—and the combination of both into a unified system for representing and constraining combinations of different event types (points, closed intervals, and open-ended intervals). We show that our theoretical results have been verified in a large-scale corpus analysis. The framework is designed to inform a temporally motivated sentence-ordering module in an implemented multi-document summarization system. 相似文献

Multi-candidate reduction: Sentence compression as a tool for document summarization tasks 总被引:2,自引:0,他引:2

This article examines the application of two single-document sentence compression techniques to the problem of multi-document summarization—a “parse-and-trim” approach and a statistical noisy-channel approach. We introduce the multi-candidate reduction (MCR) framework for multi-document summarization, in which many compressed candidates are generated for each source sentence. These candidates are then selected for inclusion in the final summary based on a combination of static and dynamic features. Evaluations demonstrate that sentence compression is a valuable component of a larger multi-document summarization framework. 相似文献

Psychological science has much to contribute to preK‐12 education because substantial psychological research exists on the processes of learning, teaching, motivation, classroom management, social interaction, communication, and assessment. This article details the psychological science that led to the identification, by the American Psychological Association's Coalition for Psychology in Schools and Education, of the “Top 20 Principles from Psychology for PreK‐12 Teaching and Learning.” Also noted are the major implications for educational practice that follow from the principles. 相似文献

This study sought to advance understanding of the potential long-term consequences of the COVID-19 pandemic for child development by characterizing trajectories of maternal perinatal depression, a common and significant risk factor for adverse child outcomes. Data came from 393 women (86% White, 8% Latina; mean age = 33.51 years) recruited during pregnancy (n = 247; mean gestational age = 22.94 weeks) or during the first year postpartum (n = 146; mean child age = 4.50 months; 55% female). Rates of depression appear elevated, relative to published reports and to a pre-pandemic comparison group (N = 155). This study also provides evidence for subgroups of individuals who differ in their depressive symptom trajectories over the perinatal period. Subgroup membership was related to differences in maternal social support, but not to child birth outcomes. 相似文献

Although parent school councils are the archetypal arrangement for engaging parents in school improvement planning, their effectiveness is negligible when it comes to building parents’ capacity for and confidence in educational decision-making. Using Arnstein’s ladder of citizen participation, this qualitative case study investigated the nature and degree of parents’ participation on six school community councils (SCCs) in Saskatchewan, Canada. Focus groups and interviews with SCC parent members, and school and district leaders were the chief data sources. In most schools, the SCC structure did not dislodge time-honoured barriers that restricted parents’ influence on extracurricular issues. A conceptual examination of participation affords a process-oriented understanding of parent involvement that complements the existing focus on the factors that impact school council effectiveness as an outcome. 相似文献
