The research access/impact problem arises because journal articles are not accessible to all of their would-be users; hence, they are losing potential research impact. The solution is to make all articles open access (OA, i.e., accessible online, free for all). OA articles have significantly higher citation impact than non-OA articles. There are two roads to OA: the “golden” road (publish your article in an OA journal) and the “green” road (publish your article in a non-OA journal but also self-archive it in an OA archive). About 10% of journals are gold, but over 90% are already green (i.e., they have given their authors the green light to self-archive); yet only about 10–20% of articles have been self-archived. To reach 100% OA, self-archiving needs to be mandated by researchers’ employers and funders, as they are now increasingly beginning to do.  相似文献

SCOAP3 is an innovative Open Access initiative for publishing in high-energy physics. The model is viewed by many as a potential solution to multiple issues related to the financial crisis, the peer review system, scholarly communication, and the need to support institutional repositories. This installment of “The Balance Point” presents articles written by three Open Access advocates, outlining the SCOAP3 proposal, benefits of participation, and some of the roles libraries, publishers and scientists can play in making important changes to scholarly communication. Contributors discuss scalability and transferability issues of SCOAP3, as well as other matters of concern.  相似文献

Recent discussions on Open Access (OA) have tended to treat OA journals and self-archiving as two distinct routes. Some supporters of self-archiving even suggest that it alone can bring about full Open Access to the world's scientific literature. In this paper, it is argued that each route actually corresponds to a phase in the movement toward Open Access; that the mere fact of self-archiving is not enough; that providing some branding ability to the repositories is needed. However, doing so will eventually bring about the creation of overlay (or database) journals. The two roads, therefore, will merge to create a mature OA landscape.  相似文献

A study conducted for the (United Kingdom) Joint Information Systems Committee reviewed possible models for implementing Open Access to research reports in institutional archives and Open Access journals. The conclusion was that a “harvesting model,” in which full texts reside on the original servers but metadata are harvested, held, and enhanced by a central service, was preferable to either a centralized national service or a completely decentralized service for the UK. The study included issues of populating institutional archives (IAs) and some form of mandatory archiving for publicly funded research results to obtain a critical mass of Open Access material in such a system.  相似文献

Open Access is increasingly considered the most logical and hopeful solution to ease the burden on library budgets, as well as the best way to unshackle research findings—its primary role. But is Open Access the panacea for all the ills that currently beset those of us dedicated to the dissemination and preservation of good quality academic research? In this article, Richard Gedye (Sales Director, Oxford Journals) explores the background to one of Oxford Journals' current Open Access initiatives and explains some elements of the model adopted. He also offers his personal opinions on the significant role librarians could play in the Open Access story.  相似文献

This paper sets Open Access (OA) publishing in the context of today's scientific, technical, and medical (STM) publishing trends. Four areas are covered: (a) a brief overview of STM publishing and its value today; (b) OA's place in the industry; (c) the underlying economics of OA, particularly its author-pays model; and (d) directions in moving towards “universal access” to STM information, where both researchers and the public have access to the scientific information they need.  相似文献

This year's panel discussion, moderated by Beverly Dowdy, offered three perspectives on the current and future trends in open access (OA) from David Crotty, a senior editor from a prominent university publisher; Beth Bernhardt, an assistant dean for collection development and scholarly communications at an academic library; and Dr. Paige Hall Smith, an associate professor at a large state university. Each discussed different opportunities and challenges that open access presents. A question-and-answer period followed, prompting further discussion of the points brought up during the presentations, as well as related issues.  相似文献

The Spanish National Research Council (CSIC in Spanish, http://www.csic.es) is the largest public institution dedicated to research with more than a hundred centers and institutes nationwide. Its main objective is to develop and promote research that will help bring about scientific and technological progress and to collaborate with Spanish and foreign entities in order to achieve it. Digital.CSIC was created to maximize the international visibility, accessibility and impact of CSIC research by taking advantage of innovations in the field of information management and by participating actively in the open access movement.  相似文献

Since January 2007, Ukraine has a law mandating open access to publicly funded research. Most of the Parliament members supported it. The law is already the second parliamentary inquiry mandating the Cabinet of Ministers to take actions on creating favorable conditions for developing open access repositories in archives, libraries, museums, and scientific and research institutions with open access conditions to publicly funded research. Nevertheless, the “bottom-up” approaches of Ukrainian universities and research centers as well as political support from the principle legislative body in the country, have still not resulted in a network of well-functioning institutional repositories. The article highlights recent open access developments and presents the lists of open access benefits for the developing and transition countries and regions.  相似文献

Lyell, a founder of the science of geology, used statistical models to describe the changes that had occurred in the earth and its environment. From this model he attempted to establish a time frame for each epoch. This article shows that Lyell's model is equivalent to the classic coupon problem included in many probability texts. Furthermore, it is shown that the time frame deduced by Lyell is inconsistent with the model he was using. The proper time frame consistent with the model is provided. A second model that was considered by Lyell is also investigated.  相似文献

At the University of Colorado at Boulder University Libraries, the Special Collections and Cataloging and Metadata Services Departments have been testing Innovative Interfaces' Millennium Media. In a recent project, librarians and staff digitized cover images and tables of contents for issues of selected journals from the Tippit Collection and linked the digitized enhancements to the catalog records for the associated titles. This article reviews the steps involved with the project, shows the results, and describes where this now ongoing effort will fit in the workflow of the departments involved.  相似文献

The slippage problem occurs when an unspecified observation in a given random sample is from a distribution other than that for all the remaining observations. This paper studies the problem in terms of the 'slip' in the mean direction of a circular normal distribution. The slippage problem is first treated as a multiple decision problem with a prior which is invariant under the permutations of the hypotheses. The probabilities of accepting the various hypotheses for the Bayes rule with respect to this prior are explicitly obtained. The likelihood ratio tests for this slippage problem, for the cases when the mean directions are both known and unknown, are shown to be easily computable. The tests are illustrated through two well-known datasets. The performances of a range of tests are compared using extensive simulation.  相似文献

限额以下贸易业抽样调查,经过几年试点,积累了许多经验,也反映出一些问题。需要认真研究,妥善处理。抽样框的确定抽样框是编制抽样单位的目录。限额以下贸易企业的调查对象是全社会从事批发、零售贸易活动,零售业年销售额在500万元以下,批发业年销售额在2000万元以下的单位以及个体户。被抽样总体中的基本单位是限额以下贸易业单位和个体户,那么抽样框的单位是什么,如何编制抽样框呢?一种方案以居委会、村委会群单元为抽样框单位; 另一种方案则以贸易业单位和个体户为抽样框单位。但在具体操作过程中并非这么简单,往往是不同的阶…  相似文献

The so-called umbrella problem (or cost-loss ratio situation), in which an individual must decide whether to take an umbrella in the face of uncertainty concerning whether it will rain today, is sometimes used as a textbook example of decision making under uncertainty. This problem is extended to provide a simple demonstration of the way in which the economic value of imperfect information changes as its quality increases.  相似文献
