It will soon be rare for research-based institutions not to have a digital repository. The main reason for a repository is to maximize the visibility of the institution’s research outputs (provide Open Access), yet few contain a representative proportion of the research produced by their institutions. Repositories form one part of the institution’s Web platform. An explicit, mandatory policy on the use of the repository for collecting outputs is needed in every institution so that the full research record is collected. Once full, a repository is a tool that enables senior management in research institutions to collate and assess research, to market their institution, to facilitate new forms of scholarship, and to enable the tools that will produce new knowledge.  相似文献

ABSTRACT

This installment of The Balance Point column delves into the ways in which libraries create and store open educational resources (OER) in institutional repositories (IR), addressing issues such as preservation and versioning of OER content, copyright and licensing, funding, and staffing. Drawing on interviews and the literature, programs at institutions such as the University of Minnesota, the University of Kansas, and Grand Valley State University are highlighted.  相似文献

本文的主要工作是从频域的角度对季节调整中“季节滤子”的设计及估计问题进行研究。通过将直接信号提取(DSEF)方法引入到季节调整的应用之中,突破现有季节调整方法中仅能处理季度或月度数据的限制,且该方法下季节调整后的序列是理论季节调整后序列的“均方误差”最小估计。将DSEF方法应用于对中国季度进出口总额序列的季节调整分析中。分析结果显示,相比于X-11和SEATS方法,DSEF方法季节调整结果的离差较小且稳健性较好。  相似文献

Since 2006, Research Online, the University of Wollongong's open access institutional repository has utilised Bepress' Digital Commons software to make available published research outputs and digital theses. This article discusses the outcomes of recent academic demand for its use as a publishing tool of university journals and conference proceedings. The Journal of University Teaching and Learning Practice is provided as an example. Digital Commons includes the editorial management software, EdiKit, which assists in managing submissions, editorial functions, and peer review. Also considered are changes to scholarly communication patterns arising out of the new open access, electronic only, publication regimes.  相似文献

Abstract

This paper reports on the developmental strategies, challenges and directions of the institutional repositories of the higher educational institutions in Hong Kong. The study integrates the size, content, full text and public accessibility of these repositories. The paper also compares archived output with research output as registered by the Hong Kong University Grants Committee. Percentages of archived work are low for journal and conference papers, but moderate for graduate theses. These deposit rates reflect the differing institutional policies. In recognizing these challenges, the Hong Kong Open Access Committee has been formed to address regional issues in knowledge sharing.  相似文献

Bootstrap方法的历史发展和前沿研究   总被引:13,自引:3,他引:10  
从1979年Efron提出Bootstrap方法至今,该方法在近30年间已经得到了极大的发展和扩充,并被广泛地应用于统计学的各个领域.Bootstrap理论的基本思想、历史发展及其若干比较前沿的研究方向包括:独立同分布数据、基于模型、带有块结构、Sieve、基于变换、Markov过程、长期相依和空间数据的Bootstrap理论,其中对独立同分布数据的Bootstrap应用最为基础,其余七种方向都可以视为附加了各种特殊条件的Bootstrap应用.由于Bootstrap的应用通常需要一定的统计程序编写,在介绍各种研究方向的同时,也相应简要介绍一些算法实现,其软件工具采用当今国际统计研究的主流语言--R语言.  相似文献

Abstract

This segment of the “Sharpest Tool” column provides an overview of the current options for authentication for electronic resources and discusses recent developments in this area. Remote access to electronic resources is increasingly important as libraries purchase more and more electronic content. This column attempts to provide a baseline use for many terms relating to authentication, while incorporating discussions and concerns surrounding recent developments in authentication methods.  相似文献

Recent developments in sample survey theory include the following topics: foundational aspects of inference, resampling methods for variance and confidence interval estimation, imputation for nonresponse and analysis of complex survey data. An overview and appraisal of some of these developments are presented.  相似文献

Summary This special issue of the Journal of the German Statistical Society presents 14 papers with surveys on the development and new topics in econometrics. The articles aim to demonstrate how German econometricians see the discipline from their specific view. They briefly describe the main strands and emphasize some recent methods.  相似文献

Graphs are presented on which the empirical distribution function can be plotted to test the assumption of normality by the Lilliefors test. A second set of graphs is presented for using the Lilliefors test on exponential distributions. The graphs allow for tests at the 10 percent, 5 percent, and 1 percent levels of significance. Use of these graphs makes it easy for students in a first course in statistics to test normal and exponential distributions without having to unravel the mystery associated with putting together a chi-squared goodness-of-fit test.  相似文献
