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
Uno studio sulle caratteristiche di un campione di pazienti internati presso l'Ospedale Psichiatrico Giudiziario di Castiglione delle Stiviere e dimessi nella regione Lazio.
Full text linkAim. The aim of this study was: i) To identify socio-demographic and clinical data in a sample of inmates in the Criminal Mental Hospital (CMH) at Castiglione delle Stiviere; ii) to assess the presence of characteristics which could foresee the commission of a crime of psychiatric interest; iii) to assess the frequency of crime repetition. Materials and Methods. This study was carried out on a sample of 38 patients. A descriptive analysis of the sample was carried out and the associations among several variables were analyzed. Results. The sample is characterized by a high frequency of schizophrenia diagnosis (73.0%), the presence of hospitalization before the commission of the crime (68.4%) and the absence of criminal precedents (71.1%). For men the age of the commission of the crime is equal to 33.72±10.6 years and for women to 45.18±11.4 years (p=0.011). The time between the onset and the commission of the crime is longer in patients who have received therapy (treatment) than in those ones with no treatment (p=0.012). About 12% of the sample committed new crimes. Conclusions. The results showed previous criminal acts are not predictive for the commission of new crimes of psychiatric interest. However many patients had previous contacts with community facilities before their first admission to hospital and the treatment extended the interval between the onset of the disease and the commission of the crime. The relapse rate after the discharge was very low if compared with samples coming from other services that offered more custodial rather than rehabilitative facilities
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
Psicoterapia psicodinamica e formazione universitaria: problematiche e prospettive
Full text linkThis article proposes a reflection on the problem of psychiatric training taking into consideration the
current situation present in Italy where, apart from public (university) schools of specialization,
there are a number of private post-graduate schools which qualify one to practice the profession of
psychotherapist. By keeping separate the more didactic-educational aspect from the training, there is
an attempt to verify how much attention is devoted to the latter because within the university schools
more and more students ask for a possibility to discuss clinical cases and understand the sense of a
therapeutic relationship. Furthermore, it is necessary to verify, not only the didactical learning of
students, but also their personal aptitudes during the four years of specialization. There seems to be
an incongruity between the statutes that govern the single private specialization schools that regulate
the supervision of clinical cases and in some cases prescribe an obligatory didactic analysis for the
student, and what happens in a university context
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
