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
Analisi del meccanismo evolutivo della frana complessa di Cervarezza
No full textLa nota riguarda l'analsi con moedllazione numerica con il Metodo DDA di un moviemnto franoso complesso che interessa il versante dove è situato il centro abitato di Cervarezza. La modellazione numerica ha lo scopo di favorire una migliore interpretazione del meccanismo di frana con una ricostruzione dei principali movimenti che si sono succeduti fino ad arrivare all'attuale morfologia del versante

A survey on the number of dog-induced injuries inflicted by pure-breed and mixed-breed dogs in Italy
Full text linkIn this survey we collected information on the number of biting events inflicted by dogs on other animals or people, recorded by local health authorities (LHAs) in Italy after an official complaint over a one-year period. The aim was to evaluate the possible differences between mixed and purebred dogs and between trained dogs and untrained dogs, and potentially highlight the most aggressive breeds. A questionnaire was developed and emailed at the beginning of 2019 to 87 LHAs located in north-central Italy asking them to report biting episodes due to dog attacks occurred in one year. The questionnaire included questions about the subject attacked and the breed of the aggressor dog with the reasons for the aggression. Only six questionnaires were received and processed. The results revealed 1169 cases of aggression in one year reported in the total of the six LHAs (194.8±115.33 as average value), especially against humans (96.9%). Among these attacks, 52.6% were against strangers and 29.8% were against a family member (owner or another family member). There were no differences in the number of attacks by pure-breed (53.6%) or mixed-breed dogs (46.6%). The German Shepherd, which is often used for protection and as a guard dog, was the breed with the highest number of biting cases reported (19.0%). However, this is essentially due to its prevalence in Italy, with over 12,000 dogs registered in the ENCI every year but also why this popular breed has been used by people as a guard dog. Of the 377 cases of registered bites, 343 (91.0%) of the dogs had not undergone any training, thus indicating that owner education programmes are fundamental tools to reduce risk factors and prevent aggression
