PurposeThis mixed-methods study integrates bibliometric and altmetric investigation with a qualitative method in order to assess the prevalence and societal-impact of Open-Access (OA) publications, and to reveal the considerations behind researchers' decision to publish articles in closed and open-access.Design/methodology/approachThe bibliometric-altmetric study analyzed 584 OA and closed publications published between 2014 and 2019 by 40 Israeli researchers: 20 from STEM (Science, Technology, Engineering, Math) and 20 from SSH (Social Sciences and Humanities) discipline. We used a multistage cluster sampling method to select a representative sample for the STEM disciplines group (engineering, computer science, biology, mathematics, and physics), and for the SSH disciplines group (sociology, economics, psychology, political science, and history). Required data were extracted from Scopus and Unpaywall databases, and the PlumX-platform. Among the 40 researchers who were selected for the bibliometric-altmetric study, 20 researchers agreed to be interviewed for this study.FindingsComparing bibliometrics and altmetrics for the general publications did not reveal any significant differences between OA and closed publications. These were found only when comparing OA and closed publications across disciplines. STEM-researchers published 59 % of their publications in OA, compared to just 29 % among those in SSH, and they received significantly more bibliometric and altmetric citations from SSH OA publications and from their own closed-access publications. The altmetrics findings indicate that researchers are well acquainted and active in social media. However, according to the interviewees, there is no academic contribution for sharing research findings on social-media; it is viewed as a “public-service”. Researchers' primary consideration for publishing in closed or OA was the journal impact-factor.Research limitations/implicationsOur findings contribute to the increasing body of research that addresses OA citations and societal-impact advantages. The findings suggest the need to adopt an OA-policy after a thorough assessment of the consequences for SSH disciplines.  相似文献

The main factors that currently contribute to the increase of the vulnerability of computer information are considered. The dynamics of a number of promising scientific research areas in the field of information security (cryptography, computer steganography, and biometric information-protection systems) are analyzed based on Russian and foreign publications from VINITI databases over the past decade. The obtained data to a certain extent reflect the direction of the development of these research areas, which is defined by corresponding publication streams.  相似文献

The citation records of 26 physicists are analyzed in order to determine the modified g index gm which takes multiple coauthorship into account by fractionalized counting of the publications. The results are compared with the original g index as well as with the h index and the respective modified h index hm. Although the correlations between these indices are relatively strong, the arrangement of the datasets is significantly different in detail depending on whether they are put into order according to the values of either the original or the modified indices.  相似文献

Australia has a well-established history of access to government information and publications by citizens, much of it through libraries. The changes in the 1990s and 2000s with the move to electronic publishing and Internet access have led to significant changes in the accessibility of information. In 1997, the Australian Government framework for electronic delivery of information service was established by the report Management of Government Information as a National Strategic Resource. Since this report, there has been a rapid increase in the availability of government information, including government publications. There has also been an increased demand for public libraries to support access. The paper reviews establishment of the initial framework and changes in the past decade. Trends in production of government information, citizens' use of electronic Australian Government publications, satisfaction with online government services, and implications for libraries are analyzed.  相似文献

Abstract

A new library in San José opened on August 1, 2003. This library is the result of a unique collaboration between San José State University Library and the San José Public Library. The planning for this new library highlighted merging several key areas of operation, including Government Publications. Several years before the two libraries merged, the University Library merged government publications reference functions into the general reference service of the Reference department. Depository library status at the federal and state levels impacted the planning and implementation stages. This paper discusses the background, planning, and implementation of merging the reference service for government publications, first within an academic environment and then in the unique joint library environment.  相似文献

Reliable methods for the assessment of research success are still in discussion. One method, which uses the likelihood of publishing very highly cited papers, has been validated in terms of Nobel prizes garnered. However, this method cannot be applied widely because it uses the fraction of publications in the upper tail of citation distribution that follows a power law, which includes a low number of publications in most countries and institutions. To achieve the same purpose without restrictions, we have developed the double rank analysis, in which publications that have a low number of citations are also included. By ranking publications by their number of citations from highest to lowest, publications from institutions or countries have two ranking numbers: one for their internal and another one for world positions; the internal ranking number can be expressed as a function of the world ranking number. In log–log double rank plots, a large number of publications fit a straight line; extrapolation allows estimating the likelihood of publishing the highest cited publication. The straight line derives from a power law behavior of the double rank that occurs because citations follow lognormal distributions with values of μ and σ that vary within narrow limits.  相似文献

Questionable publications have been accused of “greedy” practices; however, their influence on academia has not been gauged. Here, we probe the impact of questionable publications through a systematic and comprehensive analysis with various participants from academia and compare the results with those of their unaccused counterparts using billions of citation records, including liaisons, i.e., journals and publishers, and prosumers, i.e., authors. Questionable publications attribute publisher-level self-citations to their journals while limiting journal-level self-citations; yet, conventional journal-level metrics are unable to detect these publisher-level self-citations. We propose a hybrid journal-publisher metric for detecting self-favouring citations among QJs from publishers. Additionally, we demonstrate that the questionable publications were less disruptive and influential than their counterparts. Our findings indicate an inflated citation impact of suspicious academic publishers. The findings provide a basis for actionable policy-making against questionable publications.  相似文献

This paper reports on a study of librarian initiated publications discovery (LIPD) in U.S. state digital depository programs using the OCLC Digital Archive to preserve web-based government publications for permanent public access. This paper describes a model of LIPD processes based on empirical investigations of four OCLC DA-based digital depositories. The model is composed of stages including site visit, site scan, selection, re-conceptualization, and two bibliographic verification steps; action strategies at each stage and the observed practices at each site are reported. This paper also describes how librarian perceptions of web publications as discrete objects and bibliographic objects influence the selection and retention of government web content. Finally, the paper discusses several problems associated with the observed LIPD methodologies and technologies.  相似文献

The purpose of this exploratory study is to review scholarly publications and assess egovernment research efforts as a field of study specific to the United States e-government environment. Study results reveal that researchers who focus on the U.S. e-government environment assess specific e-government topics at the federal, state, and local levels; however, there are gaps in the research efforts by topic areas and across different levels of government, which indicate opportunities for future areas of research. Results also find that a multitude of methodology approaches are used to assess e-government. Issues, however, exist that include lack of or weak presentations of methodologies in publications, few studies include multi-method evaluation approaches for data collection and analysis efforts, and few studies take a theory-based approach to understanding the U.S. e-government environment.  相似文献

Metrics based on percentile ranks (PRs) for measuring scholarly impact involves complex treatment because of various defects such as overvaluing or devaluing an object caused by percentile ranking schemes, ignoring precise citation variation among those ranked next to each other, and inconsistency caused by additional papers or citations. These defects are especially obvious in a small-sized dataset. To avoid the complicated treatment of PRs based metrics, we propose two new indicators—the citation-based indicator (CBI) and the combined impact indicator (CII). Document types of publications are taken into account. With the two indicators, one would no more be bothered by complex issues encountered by PRs based indicators. For a small-sized dataset with less than 100 papers, special calculation is no more needed. The CBI is based solely on citation counts and the CII measures the integrate contributions of publications and citations. Both virtual and empirical data are used so as to compare the effect of related indicators. The CII and the PRs based indicator I3 are highly correlated but the former reflects citation impact more and the latter relates more to publications.  相似文献

The aim of this paper is to establish the similarities and differences between the way of collaboration and the production of researchers when dealing with publications or with the development of projects and whether the collaboration patterns change across disciplines.We have studied the networks of researchers formed through the collaborations in papers or in projects in a research institution (the University of Zaragoza) and we have analyzed a series of individual and global magnitudes. As a general result, we have observed that the laws governing the individual productivity are similar for the cases of publications and projects but, however, the behavior is different when analyzing more complex magnitudes such as the collaborations or other structural variables. We consider also the subnetworks defined by the researchers of the different disciplines and characterize their topologies and compare the corresponding collaboration patterns.Because of the general approach, we expect most of the conclusions to be applicable to other universities or research centers.  相似文献

Congressional journals are the only government publications mandated by the Constitution of the United States. Unfortunately, they are often overlooked in favor of the sometimes more complete Congressional Record and its predecessors. From the beginning of the Serial Set in 1817 until 1952 the Journals were printed as a part of that collection. The attached list may be used as a finding tool for those needing to use the Journals included in the Serial Set.  相似文献

From the way that it was initially defined (Hirsch, 2005), the h-index naturally encourages focus on the most highly cited publications of an author and this in turn has led to (predominantly) a rank-based approach to its investigation. However, Hirsch (2005) and Burrell (2007a) both adopted a frequency-based approach leading to general conjectures regarding the relationship between the h-index and the author's publication and citation rates as well as his/her career length. Here we apply the distributional results of Burrell, 2007a, Burrell, 2013b to three published data sets to show that a good estimate of the h-index can often be obtained knowing only the number of publications and the number of citations. (Exceptions can occur when an author has one or more “outliers” in the upper tail of the citation distribution.) In other words, maybe the main body of the distribution determines the h-index, not the wild wagging of the tail. Furthermore, the simple geometric distribution turns out to be the key.  相似文献

What future roles will publishers need to build on and develop given changes driven by the online system for the publication of research‐based information? By reviewing some of the key issues currently faced by publishers online, this article is an attempt to provide a constructive framework for working through both immediate tactical pressures and priorities, and longer‐term plans on product refinement and market needs. The areas of publishing affected by online availability are identified and contrasted with those that are not. Success rests on the ability of publishers to listen to and observe online users, to be open to the new opportunities that arise, and to be willing to adapt publications to provide value to the research community and libraries by making full and sound use of online as it becomes the dominant route for accessing research information.  相似文献

The effect of two different calculation methods for obtaining relative impact indicators is modelled. Science policy considerations make it clear that evaluating the sets of publications, the “ratio of the sums” method should be preferred over the “mean of the ratios” method. Accordingly, determining the relative total impact against the mean relative impact of the publications of teams or institutes may be preferred. The special problem caused by relating the number of citations of an individual article to the Garfield (Impact) Factor (or mean citedness) of the publishing journal (or a set of journals selected as standard) lower than zero is demonstrated by examples. The possible effects of the different share of publications in different fields on the value of the “new crown” index are also modelled. The assessment methods using several appropriately weighted indicators which result in a composite index are recommended. The acronym “BMV” is suggested to term the relative impact indicators (e.g. RCR, CPP/JCSm, CPP/FCSm and RW) in scientometrics.  相似文献

ABSTRACT

This study evaluates the usability of the Journal Finder integrated search interface, developed at the Jackson Library at the University of North Carolina at Greensboro. This interface provides electronic access to publications including journals, newsletters, newspapers, and magazines. This study was conducted to determine how intuitive and learnable the interface is for accessing online publications. The participants consist of four user subgroups: undergraduate students, graduate students, staff, and faculty. The study evaluates the efficiency and effectiveness of the interface to support the participants' tasks of accessing online publications by using pretest questionnaires, task-analysis techniques, think-aloud protocol, scenarios, and post-test questionnaires. This study also evaluates the Journal Finder online tutorial. The study finds that the Journal Finder interface is easy to use, simple to learn, efficient, and effective for all subgroups. The effectiveness error rate and efficiency-time-to-completion measurement is comparable for all four subgroups in completing their tasks. The areas recommended for improvement to enhance the intuitiveness of the Journal Finder interface are the understandability of the navigational features, icons, and terminology and the creation of an easy-to-understand online tutorial. This study is novel because it examines the efficiency and effectiveness of the interface to facilitate access to electronic publications for not only students but also for faculty and staff.  相似文献

The review of the research of the Open-Access system of journals and its advantages and disadvantages are presented. The bibliometric analysis was carried out for the array of Russian papers published in the journals of the Gold Open Access system and reflected in the SCI-E database for 2008–2017. The results of the analysis of the publication activity showed that, despite the high payments for papers, there was a steady increase in the share of Russian publications in such journals compared to the overall publication activity of Russia: from 7.8% in 2008 to 13.7% in 2017. This is largely due to active international cooperation of Russian organizations with funding agencies from the United States (31%), Germany (29%), and other industrialized countries. Analysis of the array of Gold OA publications in large research areas made it possible to establish a significant difference in its structure compared to the general array of publications in Russia. As an example, the most important scientific field in the world, Research Area Scientific Technologies, was ranked the third in comparison with the ninth rank in the general array.russian scientists widely use high-quality foreign journals of the Gold OA system, which includes one Russian journal, Solid State Physics.  相似文献

Retractions are necessary to remove flawed research from citable literature but cannot offset the negative impact those publications have on science advances and public trust. The editorial peer-review process is intended to prevent flawed research from being published. However, there is limited empirical evidence of its effectiveness in identifying issues that lead to retractions. This study analyzed the peer-review comments (provided by Clarivate Analytics) for a sample of retracted publications (provided by Retraction Watch) to investigate how the peer-review process effectively detects the areas where the retraction causes lie and whether reviewer characteristics are related to the effectiveness. We found that a small proportion of peer reviews suggested rejections during the peer review stage, while about half suggested acceptance or minor revision for those later retracted papers. The peer-review process was more effective in identifying retraction causes related to data, methods, and results than those related to text plagiarism and references. Additionally, factors such as reviewer seniority and the level of match between reviewers’ expertise and the submission were significant in determining the possibility of peer reviews identifying suspicious areas in submissions. We discussed potential insights from these findings and called for collective efforts to prevent retractions.  相似文献
