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
Casl-Chart: A Combination of Statecharts and of the Algebraic Specification Language Casl
No full textIn this paper we present Casl-Chart a formal visual specification language for reactive systems obtained by combining an already existing language for reactive systems, precisely the statecharts as supported by Statemate , with an already existing language for the specification of data structures, precisely the algebraic specification language Casl
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
BREASTCAN: the chemotherapy tool of CONQUEST
No full textBreast is the neoplasm with highest incidence and mortality in women. All over the world several millions of women have been diagnosed or will develop a breast cancer. In many cases these patients are treated in general hospitals by general clinicians, rather than by oncologists in Cancer Centers. Prescription of inadequate therapy may allow reduced patients survival or disease control. We present a decision support system for individualized prescription of post surgery therapy in breast cancer patients based on patient’s characteristic and tumor biology and extention. As a first set of validation cases we considered 20 patients whose medical records are stored at the National Cancer Institute of Genova, these patient were all treated with radical mastectomy, with satisfactory results
