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
Dramatic Illusion and Sympathetic Curiosity in Romantic Drama

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
Aspetti nutrizionali dei pasti di una mensa per i poveri : l'esperienza dell'Opera di San Francesco di Milano, Italy
No full textObjectives: We report the experience of San Francesco Opera soup kitchen in Milan. We analyzed: 1) user nationality; 2) nutritional composition of 869,516 meals served in 2014 (average 2,800 meals per day), with the aim of highlighting any nutritional deficiencies. Setting: Milan, Italy. Design: We report a quantitative analysis of macro and micronutrients of all the meals dished (database: Souci “Comparative Tables of Food”), comparing them with the reference values for the Italian population (LARN 2012). Sample: About 2,800 meals a day for 6 days a week from Monday to Saturday served in a year (2014). Menus are of two types: winter menu (7 months, from 01/01 to 04/30 and from 01/10 to 31/12) and summer menu (5 months, from 1/5 to 30/09). Results: 2039 Kcal have been dished out from winter menu (15% protein, 29% fat, 56% carbohydrate) vs 2146 kcal from summer menu (15% protein, 28% fat, 57% carbohydrate). Conclusions: Macronutrients and micronutrients are well represented both in summer and in winter menu. We report a lack of calcium, vitamin D and zinc due to the scarcity of foods such as milk and dairy products that must be integrated. Salt appears to be higher than recommended
Analysis of the concentration of gamma-emitting radioisotopes in marine fish samples
Full text linkMarine fish products (fish) represent an important source of nutrition for all mankind. In the food pyramid, fish products are located in the highest levels and therefore may absorb chemical pollutants and isotopes, thus transferring them to humans. The aim of the work was to verify the presence of gamma-emitting isotopes (131I, 137Cs, 210Pb) in a random sample consisting of 12 species of marine fish regularly caught in the oceans. The results demonstrate that there is no significant radioisotope pollution in the small sample analysed. However, the possible presence of isotopes in the marine environment should be monitored given that there are powerful nuclear weapons in the world and many ongoing conflict
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
