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
[Serum gastrin in patients with nonalcoholic liver cirrhosis]
No full textSerum gastrin before and after a low-lipid glycoprotein meal was studied in patients with viral cirrhosis (without associated alcoholism) and controls. Cirrhotics are at high risk of peptic ulceration and most authors have attributed this to their gastrin levels which in many studies are higher in cirrhotics than controls. Since such studies involved patients with cirrhosis from a variety of causes, mostly alcohol (which in itself causes a rise in gastrin levels and an increased risk of peptic ulceration), we believed it necessary to evaluate gastrin levels before and after stimulation in patients with non-alcoholic cirrhosis, i.e. in those with viral cirrhosis

No full textThe history of von Hippel-Lindau disease.
No full textvon Hippel-Lindau (vHL) disease is a heritable multisystem cancer syndrome that is associated with a germ line mutation of the vHL tumor suppressor gene on the short arm of chromosome 3. Affected individuals are at risk of developing various benign and malignant tumors of the central nervous system, kidneys, adrenal glands, pancreas, and epididymis. The name of this disease derives from two prestigious European physicians, Eugen von Hippel and Arvid Lindau, but many others played an important part in the description of the disorder. vHL disease has an old and modern history, thanks to the advent of new radiology and molecular biology diagnostic techniques
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
