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
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

Facial aesthetic and childhood
No full textAIM: The aim of the study is to evaluate attention and perception of parents about children's facial aesthetics, the paediatrician's role in early diagnosis of these problems and the areas of the face considered as the most important from an aesthetic point of view.
METHODS: The study was carried out collecting 1214 questionnaires at paediatricians waiting room in the North of Italy.
RESULTS: Most parents showed attention toward craniofacial deformities of their children and considered the paediatrician's role as very important in early diagnosis. Profile was considered more important than the front view and face's areas felt as the most important were denture, eyes and nose.
CONCLUSION: Despite public opinion, adults are concerned not only about the general health and growth of their children, but also about their facial aesthetics. They, in fact, not only judge aesthetics of the whole face, but also discriminate different views and specific areas of the face. They require, for early diagnosis of dentofacial problems, skilled attention from the paediatrician
L'importanza della durata del digiuno pre-macellazione in relazione al colore ed alla composizione in acidi grassi del fegato di broiler
No full textYellow liver is a reversible anomaly that meat inspectors of sanitary service point out in broiler slaughtering which is getting more frequent during the summer season. The liver show an increase in its size, sometimes haemorrhagic spots and a yellow colour that looks like that of fatty liver. This kind of anomalyhas been correlated to an inadequate time of feed withdrawal. An experiment was carried out to evaluate the effect of a prolonged time of feed withdrawal on liver appearance (colour), weight and fatty acids composition. In this regard an homogeneous batch of male broilers, forty-six days old, has been split into nine groups slaughtered every three hours of feed withdrawal. The colour of the liver, yellow at low time of feed withdrawal, turned to red at the longer time of feed withdrawal. The composition of liver fatty acids showed a marked reduction in the oleate content as feed withdrawal time raising, while a few polyunsaturated long chain fatty acids like arachidonate, eicosapentanoate and docosahexanoate, showed higher levels as feed withdrawal time rising. By Italian law, DPR n° 495 - 10/12/1997 (92/116/UE), meat that shows such kind of anomaly cannot be used as food for human
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
