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
What Notice Did
Full text linkIn the 21st century, copyright protection is automatic. It vests in eligible works the instant that those works are first embodied in a tangible format. Many Americans are unaware of that, believing instead that registration and copyright notice are required to secure a copyright. That impression is understandable. For its first 199 years, United States copyright law required authors to take affirmative steps to obtain copyright protection. The first U.S. copyright statute, enacted by Congress in 1790, required the eligible author of an eligible work to record the title of the work with the clerk of the court in the author\u27s local district, deposit a copy of the printed title with the clerk\u27s office, cause a copy of the registration record to be printed for four weeks running in a newspaper, and deliver a copy of the published work to the Secretary of State. Twelve years later, Congress added an additional requirement: copyright owners must place a prescribed copyright notice on every copy of a copyrighted work. In 1909, Congress eliminated the registration and deposit pre‐requisites for protection, but retained until 1978 the requirement that accurate copyright notice appear on every copy of a work. For 176 years of United States copyright history, then, accurate copyright notice was essential to securing a copyright in almost all works. Publishing copies of a work without copyright notice, or with the wrong name in the notice, was fatal to copyright protection
Before and After the Copyright Wars
No full textJessica Litman, the John F. Nickoll Professor of Law at the University of Michigan, delivered the 2018 David L. Lange Lecture in Intellectual Property, Before and After the Copyright Wars. Prof. Litman is the author of Digital Copyright, which traces the history of lobbying that led to the passage in 1998 of the Digital Millennium Copyright Act. She is also the co-author, with Jane Ginsburg and Mary Lou Kevlin, of the casebook Trademarks and Unfair Competition Law: Cases and Materials. Before rejoining the Michigan faculty in 2006, she was a professor of law at Wayne State University in Detroit, a visiting professor at New York University School of Law and at American University Washington College of Law, as well as a professor at Michigan Law from 1984 to 1990
Pseudoanthidium gregoriense
No full textPseudoanthidium gregoriense Pseudoanthidium gregoriense was described by Nobile (1990) as an island endemic from Sicily. Originally described as a subspecies of P. alpinum, Nobile later raised P. gregoriense to species status (1995). As mentioned above for Stelis leucostoma, Nobile (1995) draws parallels between P. gregoriense, P. leucostoma and P. lituratum. We examined four specimens of this taxon identified by Nobile (including one of his paratypes) and a photograph of the holotype, plus two other female specimens from Sicily. These specimens agree with our concept of P. stigmaticorne.Published as part of Litman, Jessica R., Fateryga, Alexander V., Griswold, Terry L., Aubert, Matthieu, Proshchalykin, Maxim Yu., Divelec, Romain Le, Burrows, Skyler & Praz, Christophe J., 2022, Paraphyly and low levels of genetic divergence in morphologically distinct taxa: revision of the Pseudoanthidium scapulare complex of carder bees (Apoidea: Megachilidae: Anthidiini), pp. 1-51 in Zoological Journal of the Linnean Society 195 (4) on page 26, DOI: 10.1093/zoolinnean/zlab062, http://zenodo.org/record/581727

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
