La formazione sulle dipendenze patologiche: possono i Ser.D. avere una funzione didattica vicariante nei confronti dell'Università? Alcune opportunità da non tralasciare
No full textThe substance use disorder is probably the most prevalent disease in our country. The training of health workers is undeniably a crucial issue in order to deliver to those who suffer from an addiction an useful treatment. This article illustrates a decade of intense training activity undertaken by a small group of physicians, sourced from Ser.D., and pharmacists which has been able to play a significant role in the local University and, therefore, in other important events connected
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Una benzodiazepina fuori dal coro. Le potenzialità d'abuso del lormetazepem
No full textLe benzodiazepine sono farmaci di largo consumo in molti paesi del mondo tra cui l'Italia. E' noto il loro potenziale di produrre dipendenza ed una delle raccomandazioni delle maggiori linee-guida internazionali sull'uso delle benzodiazepine è di evitare il più possibile l'uso cronico. Un aspetto particolare in crescita è l'uso di benzodiazepine da parte di tossicodipendenti, soprattutto da eroina. Frequentemente nei srvizi delle tossicodipendenze si osservano soggetti con dipendenze miste includenti BZD, tuttavia sono ora anche presenti soggetti dipendenti da sole BZD. Nel presente studio si presentano i dati delle Medicina delle Dipendenze dell'Azienda Ospedaliera di Verona, che evidenziano un emergente problema di abuso legato in particolare al lormetazepam sotto forma di gocce
Storie di ordinaria follia. Due casi tipici di megadosi di benzodiazepine
No full textVengono descritti due casi particolarmente significativi di utilizzo di benzodiazepine a dosaggi estremamente elevati. Un caso coinvolge il bromazepam, l'altro il zolpidem ipnotico appartenete ai cosiddetti Z-drugs. Viene anche descritta la tecnica di disintossicazione attuata con successo in entrambi i casi
Immunogenicity, reactogenicity and adherence to a combined hepatitis A and B vaccine in illicit drug users
No full textAims The use of illegal drugs is associated with an increase in infective risk for the hepatitis viruses, against which the vaccination of drug users (DUs) is recommended unanimously. The aim of the study was to determine tolerability, adherence and immune response of a combined vaccine providing dual protection against hepatitis A virus (HAV) and hepatitis B virus (HBV).
Methods The vaccine was administered to 38 DU, attending three public health centres for drug users in northern Italy, with a three-dose schedule (at 0, 1 and 6 months). The vaccine was well tolerated: only one adverse reaction (fever) was recorded after the 110 doses administered (0.9%). The vaccine schedule was completed successfully in 35 cases (92.1%). At month 8, in 34 subjects (89.5%) antibody response was evaluated: all showed seroprotection for HAV and in 33 subjects (97.1%) for HBV.
Conclusions The vaccine, studied for the first time in DUs, proved to be safe, well accepted and immunogenic; anti-HAV response was 1272 mIU/ml and 1726 mIU/ml for anti-HBV, titres lower than reported in literature for the general population. This study suggests that DUs who are HAV/HBV-negative could be vaccinated with combined vaccine
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
