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
Resumption of spontaneous erections in selected patients affected by erectile dysfunction and various degrees of carotid wall alteration : Role of tadalafil - Commentary
No full textObjective: To evaluate the possible improvement of sexual activity following a non on-demand administration of a long half-life selective inhibitor of phosphodiesterase type 5 (PDE-5) in elderly patients without major cardiovascular risk factors. Methods: Sixty subjects with erectile dysfunction (ED) aged 60-70 years and 30 control patients aged 18-40 years, affected by psychogenic ED, were studied. All underwent routine and hormonal blood tests, Nocturnal Penile Tumescence Rigidity Monitoring test (NPTRM), ultrasonographyc evaluation of common carotid artery intima-media thickness (IMT) and penile colour Doppler ultrasonography (P-CDU). All patients underwent therapy with tadalafil 20 mg in alternative days, non on-demand, at 5.00 p.m., for three consecutive months. IIEF-5, NPTRM test and P-CDU were re-evaluated one month after the end of the therapy. Results: Among elderly subjects 20 (33%) had normal carotid IMT ( 1.3 mm). NPTRM and P-CDU parameters were inversely related to different degrees of carotid wall alteration and showed a significant improvement respect to pre-treatment only in patients without atherosclerotic plaques. Also IIEF-5 showed significant improvements only in patients without atherosclerotic plaques. Conclusions: In elderly subjects with slight or no signs of vascular disease at the carotid level, chronic and non on-demand treatment with tadalafil can induce spontaneous resumption of erections, probably through the improvement of endothelial function, but direct evidences to confirm this hypothesis are required
Frank G. Jackson Interview, 11 August 2014
No full textFrank G. Jackson, mayor of Cleveland, discusses his interactions with Cleveland State University (CSU), his political history, and the projects he has implemented as mayor. He mentions his path to get his various degrees, and how he felt while he was getting these degrees. He also talks about the atmosphere at CSU and how it was different from where he started at Cuyahoga Community College. After his education he talks about his political career, and how he has had a unique experience being on both the legislative and executive side in the governance of a city. While talking about his political career, he discusses the various projects that he and the city government are working on like the new Group Plan and Opportunity Corridor. Finally, he points out the importance of the succession of leadership at CSU, and how that leadership has made CSU as great as it is today
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
