Abstract

When the International Standard Serial Number (ISSN) was created in the 1970s as an identifier of journal titles, electronic formats of serials did not exist. As electronic formats of articles emerged for the same creative content, the ISSN changed from a work identifier to a manifestation (format) identifier. This article explores the role of the ISSN as a manifestation identifier of a serial in the electronic and paper environments and questions its suitability as such in linking citations to online articles.

Abstract

As a result of inaccurate displays of journal metadata in e-content access tools and on Web sites, researchers and readers do not find the content they are seeking, and the full value of e-content services is not realized. A group will be formed later this year to develop a set of NISO best practices for presentation of e-journal titles, provision of correct ISSN information, and other basic bibliographic data on provider Web sites and in other e-content products.  相似文献

Since 2000, an Ulrich's Periodicals Directory (Ulrich's) employee has been located in the Library of Congress's U.S. ISSN Center at the Library of Congress to assign ISSN and create records for both Ulrich's and the international ISSN Register/CONSER database. How this arrangement came about, how it has succeeded over the past ten years, and the broad potential for this partnership becoming a model in both organizations for future automated data sharing and data linking is the subject of this article.  相似文献

ABSTRACT

The purpose of the study is to evaluate electronic usage statistics for Belk Library at Elon University. The Electronic Resources Office (ERO) collects usage data for all serials—both print and electronic—, ebooks, and electronic databases. This study used ezPAARSE and Google Analytics to analyze the data from our website, and we will use these data to compare our vendor statistics to get a more complete picture of how the library's electronic resources are being used.  相似文献

ABSTRACT

A number of factors can make it difficult to consistently and accurately identify individual researchers and their scholarly activities. One solution is to use unique author identifiers. Many author identifiers are available from inside and outside the library community. This column will, in lay terms, compare Scopus Author ID, ResearcherID, ORCID identifier, and ISNI (International Standard Name Identifier)—some of the more commonly used author identifiers—and explore the advantages and disadvantages of each. It will examine the differences among the four identifiers and their relationships to one another.  相似文献

Abstract

Perceptive readers may have observed, and regretted, the absence of any discussion of card catalog closings, abolition of serials departments, changes in clerical procedures, or minutiae or any of the other concrete details of library operations so dear to the hearts of us all. The craft of serials management has scarcely been mentioned. Those topics discussed — the nature of organizational change, influencing change, communication, planning for the optimum impact of automation and for flexibility throughout the development and implementation phases — are concepts difficult to introduce into the pragmatic world of libraries. It is difficult to identify causes, to predict effects, and to deal with them. These are, however, critical elements in the success or failure of a serials automation project and a library administration which addresses these issues will manage the changes brought about by automation rather than passively submitting to its consequences.  相似文献

Abstract

Sample size calculation is an important component in designing an experiment or a survey. In a wide variety of fields—including management science, insurance, and biological and medical science—truncated normal distributions are encountered in many applications. However, the sample size required for the left-truncated normal distribution has not been investigated, because the distribution of the sample mean from the left-truncated normal distribution is complex and difficult to obtain. This paper compares an ad hoc approach to two newly proposed methods based on the Central Limit Theorem and on a high degree saddlepoint approximation for calculating the required sample size with the prespecified power. As shown by use of simulations and an example of health insurance cost in China, the ad hoc approach underestimates the sample size required to achieve prespecified power. The method based on the high degree saddlepoint approximation provides valid sample size and power calculations, and it performs better than the Central Limit Theorem. When the sample size is not too small, the Central Limit Theorem also provides a valid, but relatively simple tool to approximate that sample size.  相似文献

Abstract

Motivated by Caginalp and Caginalp [Physica A—Statistical Mechanics and Its Applications, 499, 2018, 457–471], we derive the exact distribution of X/Y conditioned on X?>?0, Y?>?0 for more than ten classes of distributions, including the bivariate t, bivariate Cauchy, bivariate Lomax, Arnold and Strauss’ bivariate exponential, Balakrishna and Shiji’s bivariate exponential, Mohsin et al.’s bivariate exponential, Morgenstern type bivariate exponential, bivariate gamma exponential and bivariate alpha skew normal distributions. The results can be useful in finance and other areas.  相似文献

ABSTRACT

Two Bayesian models with different sampling densities are said to be marginally equivalent if the joint distribution of observables and the parameter of interest is the same for both models. We discuss marginal equivalence in the general framework of group invariance. We introduce a class of sampling models and derive marginal equivalence when the prior for the nuisance parameter is relatively invariant. We also obtain some robustness properties of invariant statistics under our sampling models. Besides the prototypical example of v-spherical distributions, we apply our general results to two examples—analysis of affine shapes and principal component analysis.  相似文献

Abstract

Michael Norman, head of serials cataloging at University of Illinois at Urbana-Champaign (UIUC) library, describes his library's development of an integrated management system for serials, the Online Research Resources (ORR). The ORR was designed to draw together and deliver to the public a wide range of information related to the library's serial holdings that previously could only be obtained by consulting a number of sources. With a single search, UIUC patrons can now consult the ORR for serials information such as variant titles, online availability, subject categories, print summary statements, ISI impact factor, where the title is indexed, and whether it is peer reviewed—an innovation sorely needed and highly welcomed by librarians and patrons alike.  相似文献

Abstract

Conflict management studies and the communication needs addressed by the NASIG Core Competencies standards will be the framework for how to communicate electronic resource management to library stakeholders. This article provides both theory and praxis as it is applied at Kansas State (K-State) Libraries for electronic resource access ticket resolution. The librarians responding to these tickets at K-State Libraries assessed their communications and workflows in the past year to provide a more effective customer service model. This provides evidence of technical services having public-facing elements in its core activity.  相似文献

Abstract

Name authority control—the process of selecting and maintaining a set of headings or access points for named entities—brings consistency to names in online systems and can help users locate needed items and identify related materials. Linked data provides the opportunity to extend name authority data sets and make them available to wider audiences. This column seeks to provide an overview of the landscape of local name authority projects using linked data, along with practices, challenges, and other considerations in this area.  相似文献

ABSTRACT

Such is the grip of formal methods of statistical inference—that is, frequentist methods for generalizing from sample to population in enumerative studies—in the drawing of scientific inferences that the two are routinely deemed equivalent in the social, management, and biomedical sciences. This, despite the fact that legitimate employment of said methods is difficult to implement on practical grounds alone. But supposing the adoption of these procedures were simple does not get us far; crucially, methods of formal statistical inference are ill-suited to the analysis of much scientific data. Even findings from the claimed gold standard for examination by the latter, randomized controlled trials, can be problematic.

Scientific inference is a far broader concept than statistical inference. Its authority derives from the accumulation, over an extensive period of time, of both theoretical and empirical knowledge that has won the (provisional) acceptance of the scholarly community. A major focus of scientific inference can be viewed as the pursuit of significant sameness, meaning replicable and empirically generalizable results among phenomena. Regrettably, the obsession with users of statistical inference to report significant differences in data sets actively thwarts cumulative knowledge development.

The manifold problems surrounding the implementation and usefulness of formal methods of statistical inference in advancing science do not speak well of much teaching in methods/statistics classes. Serious reflection on statistics' role in producing viable knowledge is needed. Commendably, the American Statistical Association is committed to addressing this challenge, as further witnessed in this special online, open access issue of The American Statistician.  相似文献

Abstract

Avalanche Magazine, an artist magazine published in the 1970s, is a unique primary source document of the conceptual art scene. Replete with photographs, advertisements, artist interviews, and gossipy personal notices, it is a trove of insight into artistic practice in a highly experimental period. Nevertheless, it was never included in any visual art or humanities database index, leaving its content largely undiscoverable by traditional means. In an effort to remedy this situation, the authors built an open access website, Avalanche Magazine Index (http://avalancheindex.org), which indexes the entire contents of Avalanche. Like a traditional periodical index, Avalanche Magazine Index describes the content of the magazine rather than reproducing it in full text. However, unlike traditional indices, the website encompasses every component of the magazine—from interviews to advertisements—and attempts to identify each named artist, venue, exhibition, curator, and photographer. The exhaustive indexing works in concert with the relational database that underlies the site to reveal a network of relationships between and within the artistic communities of the era. This case study presents the rationale for indexing Avalanche Magazine, provides an overview of workflow, outlines the ways the project diverges from traditional indexes, reflects on the impact of open access on the project’s success, and proposes that the website is capable of generating new knowledge in and of itself.  相似文献
