Correctly Linking Researchers to Their Journal Articles: An Overview of Unique Author Identifiers

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.     

Object detection in multi-epoch data

In astronomy multiple images are frequently obtained at the same position of the sky for follow-up coaddition as it helps one go deeper and look for fainter objects. With large scale panchromatic synoptic surveys becoming more common, image co-addition has become even more necessary as new observations start to get compared with coadded fiducial sky in real time. The standard coaddition techniques have included straight averages, variance weighted averages, medians etc. A more sophisticated nonlinear response chi-square method is also used when it is known that the data are background noise limited and the point spread function is homogenized in all channels. A more robust object detection technique capable of detecting faint sources, even those not seen at all epochs which will normally be smoothed out in traditional methods, is described. The analysis at each pixel level is based on a formula similar to Mahalanobis distance.     

What Librarians Can Learn from Cable Television: Thoughts on Transformative Business Models and Their Impact on the Business of Libraries

This column explores three issues currently dominating the discourse in the electronic resources field—the big deal, perpetual access, and open access—and draws parallels to events and trends from outside libraries that may provide some insight into where we are headed.     

Electronic Journals: Cataloging and Management Practices in Academic Libraries

The growth and availability of electronic journals offer libraries the opportunity to provide end users with quick and easy access to more journals than ever before, thereby creating a complex new workload in academic libraries. Libraries have addressed the evolving challenges unique to electronic resources by creating new policies and workflows and dedicating staff to work on the processes, despite the lack of best practices. In the fall of 2009, a survey was distributed to ninety-five libraries at peer institutions to gather information about their policies and practices for cataloging and managing electronic journals in order to gauge the current status of electronic journal management among these peer institutions. This paper reports on the survey findings related to cataloging approach, sources for bibliographic records, methods for identifying problems, and the staff and staff hours dedicated to electronic journals.     

数字金融、数字鸿沟与多维贫困

以互联网为基础的第三次技术革命,推动了数字金融的发展,对居民经济行为的影响巨大,因而也可能具有减贫作用。本文首次利用中国数字普惠金融发展指数和中国家庭追踪调查(CFPS)的匹配数据,通过克服内生性的工具变量估计,探讨了数字经济发展对家庭多维贫困的影响。然而,与预期不同,本文的初步研究发现数字金融发展提升了贫困发生的概率,也加深了多维贫困的程度,且影响逐年增大。不过,进一步研究表明,数字金融发展可能存在结构性问题:数字金融发展给能够接触到互联网的居民带来便利以及机会,挤占了未能接触到互联网的居民原先所可能获得的资源,这种数字鸿沟使得位于贫困线附近和贫困线以下的居民由于数字金融的发展而愈加贫困。观察背后机制发现,数字金融发展主要导致了面临数字劣势的贫困居民失业概率的提升。因此,在推进数字金融发展的同时,应着力提高金融服务的覆盖率和可得性,尤其对于农村的贫困人口而言,积极应对数字经济对就业市场的挑战,引导其成为脱贫攻坚的重要支撑。     

Serial Publications in the Center for Research Libraries

This article has been limited to describing the Center's activities in regard to serial publications. The reader should be reminded that the materials described in this article form only a part of the Center's collection. Excluding government documents, serial publications alone account for about 600,000 of the over 3,000,000 volumes held by the Center. The Center's printed Catalogue presently consists of 12 volumes of monographic titles, but only three volumes of serial titles. In addition to this, the Center holds over 500,000 foreign doctoral dissertations, 85,000 textbooks, 45,000 children's books, 125,000 college catalogs and several smaller collections of monographic materials which are shelf cataloged and thus do not appear in the printed Catalogue. erial publications thus form only one part of the Center's total collection. That it is a significant part is indicated by the fact that the publications described in this article, current issues and backfiles of journals and newspapers, account for nearly 60% of the material borrowed from the Center.

2011 Association of College and Research Libraries Conference

The 2011 Association of College and Research Libraries (ACRL) conference theme, “A Declaration of Interdependence,” linked the conference to its physical location, Philadelphia, Pennsylvania. The all-conference reception on Friday night in the six-year-old National Constitution Center expressed the theme perfectly. Held biennially, the 2011 ACRL conference attracted its highest attendance ever: over 5,000 attendees (some virtual), vendors, speakers and guests. Attendee demographics were decidedly younger than those seen at recent general American Library Association (ALA) conferences.     

2011 Association of College and Research Libraries Conference

Abstract

The 2011 Association of College and Research Libraries (ACRL) conference theme, “A Declaration of Interdependence,” linked the conference to its physical location, Philadelphia, Pennsylvania. The all-conference reception on Friday night in the six-year-old National Constitution Center expressed the theme perfectly. Held biennially, the 2011 ACRL conference attracted its highest attendance ever: over 5,000 attendees (some virtual), vendors, speakers and guests. Attendee demographics were decidedly younger than those seen at recent general American Library Association (ALA) conferences.
