Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
The Southwestern Association of Parasitologists: The First 35 Years: 1967–2002
Get PDFFirst two paragraphs:
It is likely that the idea to organize southwestern parasitologists into a regional group originated over cocktails one night in the late 1950s during a regional or national meeting. What is clear is that two men—Drs. Robert E. Kuntz and Donald V. Moore— were instrumental in turning the idea into what has become, in reality, the Southwestern Association of Parasitologists (SWAP).
Dr. J. Teague Self (personal communication, 1981) stated, “The beginning of SWAP was an idea of Robert Kuntz who felt that something could be gained if several of us here in the southwest could get together once a year for a day or two and just talk parasitology.” Dr. Moore (personal communication, 1980) noted that he and others “... made an early attempt to organize the regional parasitologists at a meeting of the Texas Conference on Diseases in Nature Transmissible to Man, in the spring of 1957 or 1958. After the meeting, we surveyed by mail the persons residing in Texas, Louisiana, Oklahoma and Arkansas. We received a moderately favorable response. We failed to get off the ground because certain persons failed to carry out their assignments” (see scanned, original letters from Moore, January 25, 1980, and Kuntz, February 1, 1980, Appendix, pp. 1-5). In spite of this, Kuntz, Moore and others retained an avid interest in putting together such an organization and they continued to talk about it at annual meetings
Revisiting the Code: Clarifying Name-Bearing Types for Photomicrographs of Protozoa
Get PDFIn 1988, Bandoni and Duszynski argued that individuals involved in the taxonomy and systematics of the coccidia should become familiar with the 3rd edition of the Code of Zoological Nomenclature (Ride et aI., 1985) and tried to reiterate the importance and utility of designating some form of type specimens and archiving them in appropriate museums. Their intent was to create an awareness among biologists working with coccidia (or other protists) of the value of designating type specimens. In the decade since their admonition, bench scholars working with coccidia, and journal editors to whom they submit their work, have begun to endorse the type concept by requiring that some form of type specimen be submitted before new species names and descriptions are published. Although some authors still submit samples of oocysts preserved in standard fixatives (for reasons why this option is less than optimal, see Duszynski and Gardner [1991]), the majority submit photomicrographs of sporulated oocysts as their type species to various accredited museums. The issue that arises is what to call these kinds of type specimens.
Proposed here is to add the prefix photo- to appropriate terminology already sanctioned by the Code to help clarify existing terminology. Because increasing numbers of photomicrographs are being submitted to accredited museums to archive new species, there seems a need for precise definitions, so those who submit photomicrographs of sporulated oocysts and/or other life cycle stages of coccidia will know, unambiguously, how to define their name-bearing type specimen
