Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
ウェブのユーザビリティ調査事例: ピッツバーグ大学 [Usability survey of library website : A case study of the University of Pittsburgh]
Full text linkデジタル時代のいま，大学図書館に求められていることは、館内での対人サービスよりもオンラインでの情報検索がいかに使いやすいかである。ピッツバーグ大学図書館の2006 年度の統計によると，オンラインの図書館利用回数は館内でのサービス利用回数の10.9 倍であることが分かった。図書館ウェブサイトが利用者にどれほど使いやすくデザインされているかを知るために，2007 年11 月、ユーザビリティ調査を行った。調査の結果から、ウェブデザインの改善と検索ボックスの一本化が必要であることが分かった。次世代OPAC にその解決策の1 つがあるようだ。 [In this digital age, users look for more usability of online searches than onsite services for university libraries. Based on the 2006 fiscal year statistics of the University of Library System, the number of online access to the library resources is 10.9 times more than the number of onsite services. We conducted a usability test in November, 2007, in order to investigate how well the users understood the website. We found out that we have to improve the design of the website and centralize the search boxes. There to be a solution with the next generation OPAC.
学生が図書館をもっと利用するように大学図書館が変ります[University Libraries are Changing to Encourage More Student Use]
Full text linkDramatic decrease of users in reference services is a trend observed all around the world. Rather than talking with students face to face at the library, we librarians provide virtual reference with email and instant message. On the other hand, there are increasing numbers of students who use libraries as their study rooms, to write papers, and to hold group meetings. The University Library System (ULS) of the University of Pittsburgh is undergoing a change so that students can make more use of information services, libraries’ most important function. This paper discus about ULS’s effort to meet users’ need and explore new role in the digital age, including introducing PittCat+ as a new online catalog like Google, in class instructions with LibGuides, D-Scribe Digital Publishing as an e-journal publisher, D-Scholarship as university repository, etc
米国大学図書館におけるGIS サービスの動向 －過去のアンケート調査の比較とピッツバーグ大学図書館の現状から [Trend of GIS services in US Academic Libraries –from comparison of past surveys and current situation of the University of Pittsburgh]
Full text link本稿は，米国大学図書館が1990 年代前半から提供し始めたGIS（Geographic Information Systems）サービスの動向と将来の展望を，過去のアンケート調査と著者の追跡調査，GIS 教育との関わりを通して考察する。大規模大学図書館ではすでに90％の普及率に達しているが，今後利用者を増やしていくには，しっかりしたデータ・コレクション・プランが必要であると考えられる。また，中規模，小規模大学図書館はまだ20～30％の普及率でこれからも伸びるであろうが，より充実したGIS サービスを提供していくには，学科や学部との共同作業が望ましいと思われる。 [This paper studies trends and the prospects for future of GIS (Geographic Information Systems) services in U.S. academic libraries, which have started in early 1990s, based on past surveys, my follow-up survey, and relation with GIS education. Libraries at the doctoral/research universities offer GIS services almost 90% already, but they need to have a good data collection plan in order to increase users. Libraries at the master’s colleges and universities, and the baccalaureate colleges offer GIS services only 20-30% but its proportion will be increased in near future. They would better to do joint efforts between libraries and other departments on campus regarding the use of GIS for better services.
