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
Professional liability in psychiatry:evolution and critical issues
No full text: The aim of the article is to present the evolution of professional liability in psychiatry from law 36 of 1904 to today. Through an examination of the doctrinal positions and of the jurisprudential expression it was possible to highlight three distinct phases in which professional responsibility has declined over the years. A custodial phase, in which the spirit that animated the law of psychiatric assistance was inspired by principles of social defense and the responsibility of the psychiatrist was recognized mainly in the lack of custody of the psychiatric patient. A phase of indulgence, in which, like other disciplines, the psychiatrist was recognized with "reduced impunity" due to an alleged "special difficulty" in exercising the medical profession. A phase of empowerment, in which the doctor in general, and the psychiatrist in particular, was confronted with empowering positions that led to convictions. An examination of the application of the guarantee position to psychiatry allows us to highlight current difficulties, sometimes a legacy of the past.The aim of the article is to present the evolution of professional liability in psychiatry from law 36 of 1904 to today.

KAWASAKI DISEASE IN SARDINIA: A SINGLE-CENTER EXPERIENCE
No full textBackground. Kawasaki disease (KD) is an acute systemic vasculitis affecting young children, potentially fatal if not promptly diagnosed and treated. No study exists on KD in the island of Sardinia.
Objective. To investigate the incidence and characteristics of KD in North Sardinia.
Methods. We performed a 6-year (2009-2014) cross-sectional analysis of KD records at the Pediatric Clinic, University of Sassari, Sassari, Italy.
Results. Seventeen children (mean age= 28 ± 26 months; M=9) were identified, among whom 13 (76%) were aged below 5 years and the youngest was a 5-month-old baby. The overall incidence was 10/100.000, similarly to that reported in western countries, with no seasonality. The clinical records were available for 9 out of the 17 patients. Five of nine (56%) children (mean age 4.5 years; range 16 months-6 years) had complete KD at presentation, 3/9 (33%) had incomplete KD (23, 46 and 48 months; mean age 3.5 years) and only a 33-month-old boy had atypical KD (11%). Intravenous immunoglobulin (IVIG) therapy was given to all but one, because of the delayed diagnosis. A high risk for coronary aneurisms was detected in 3/9 children (33%), two of them with complete and one with atypical KD; all responded to IVIG.
Conclusion. This is the first study on KD in a cohort of Sardinian children. An increased awareness among pediatricians that incomplete and atypical forms represent almost half of all forms of KD is essential to establish an early diagnosis and to prevent the worsening and cardiac complications of the disease
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
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
LA MALATTIA DI KAWASAKI NELL’AREA DEL NORD SARDEGNA: 6 ANNI DI ESPERIENZA DI UN SINGOLO CENTRO PEDIATRICO
No full textIntroduzione. La malattia di Kawasaki è una malattia acuta febbrile caratterizzata da vasculite sistemica e complicanze alle arterie coronarie se non trattata. Obiettivi. Lo studio riporta le caratteristiche epidemiologiche e cliniche della MK in età pediatrica nei 6 anni di esperienza di un singolo Centro Pediatrico della Sardegna.
Metodi. I casi di MK sono stati individuati retrospettivamente dai registri di dimissione ospedaliera e i dati clinici sono stati ottenuti dalla consultazione delle cartelle cliniche individuali. Sono stati effettuati due studi, uno epidemiologico e uno clinico. Lo studio epidemiologico ha preso in considerazione il periodo tra il 2009 e 2014 mentre lo studio clinico ha riguardato i casi più recenti, dal 2011 al 2014. L’analisi statistica è stata effettuata tramite il test del 2, considerando significativo p < 0,05.
Risultati. Lo studio epidemiologico ha interessato 17 pazienti (9 M- 8 F; età media = 2.3 anni ± 26 mesi), la maggior parte dei quali di età < 5 anni (76%) con il più giovane di 5 mesi di età. Analizzando il mese d'esordio, la MK ha mostrato una distribuzione uniforme con una lieve fluttuazione nei mesi di marzo e ottobre. L’incidenza di MK è risultata essere quella riportata nei Paesi occidentali, con circa 10 casi/100.000 ab/anno. Lo studio clinico ha interessato 9 dei 17 pazienti. I criteri diagnostici della forma classica erano presenti in 5/9 (55%) casi (media 4.5 anni, range 16 mesi-6 anni), mentre 3/9 (33%) hanno presentato forme incomplete (23, 46 e 48 mesi; età media 3.5 anni). Il caso atipico ha riguardato un bimbo di 33 mesi (11%). La terapia con Ig IV è stata effettuata in tutti i pazienti eccetto uno, in cui non è stata possibile a causa di diagnosi tardiva. Le complicanze cardiologiche, osservate in 3/9 casi (33%), due con forma classica e quello con forma atipica, si sono risolte con la terapia con Ig IV.
Conclusioni. I risultati del presente studio dimostrano che la MK è presente anche nel nostro territorio. La consapevolezza da parte dei pediatri che le forme incomplete e atipiche rappresentano quasi la metà dei casi è indispensabile per poterla diagnosticare e trattare adeguatamente, così da prevenire le sue complicanze cardiovascolari
