No full textSalmonellae in the Parma River: 2 years of monitoring
No full textDuring the period April 1987-February 1989 the contamination of Parma river by Salmonella was studied. These pathogens were almost constantly isolated all over the period of survey (91.7% of samples were positive). The concentration of Salmonella Spp, evaluated as MPN/1, appeared to be also remarkable, ranging from 1 to 92/l. The variety of serotypes appeared furthermore considerable either regarded on the whole (38 serotypes) or related to the single drawings (from 2 to 14 serotypes simultaneously present in 90.9% of samples). Some serotypes as: S. typhimurium, S. livingstone, S. brandenburg, S. panama, have been recovered from most of samples, some others as S. give, S. Stanleyville, S. agona have been recovered only in a few times
Influenza vaccination coverage in lombardy region: A twenty-year trend analysis (1999-2019)
Full text linkRecent events and phenomena, such as A(H1N1) pandemic in 2009, “Fluad case” (2014-2015) and the spread of vaccine hesitancy, affected influenza vaccination coverage rates in Italy. In this study, the annual coverage rates in Lombardy Region and in Italy (from 1999-2000 season) have been critically described and compared. Regarding both the general population and the elderly over-65s, Lombardy’s coverages always remained consistently below the national average. However, declines and peaks occurred simultaneously. The current slight recovery, both at national and regional level, is not sufficient. Coverages are still widely below the recommended thresholds
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
Antipoliomyelitis immunity status among a population that was regularly vaccinated 11-12 years before
No full textA study of poliomyelitis neutralizing antibodies was carried out on 165 samples of blood serum drawn from subjects aged 14-15 years who had completed vaccination with OPV 11 or 12 years ago. Two different methods of incubation of the serum-virus mixtures (1 hour at 37 degrees C; 6 hours at 37 degrees C and then 18 hours at 4 degrees C, respectively) and two different cell lines (RC-37 and Hep-2) for the inoculation of these mixtures were employed. The results were also evaluated in relation to different initial dilutions of the sera (from 1:4 to 1:1). With the 1:4 initial serum dilution the highest frequencies of sero-negativity were observed utilizing the short incubation time and inoculation in Hep-2 (42% for polio 1, 10% for polio 2, 32% for polio 3). These frequencies diminish significantly utilizing the RC-37 cell line and the long incubation respectively. Under all the experimental conditions the results were better when the 1:2 initial serum dilutions were employed and even better when undiluted sera were used. Neutralizing antibodies against the 3 types of poliovirus were detected in the undiluted sera of all the subjects utilizing the long incubation and inoculation in either the RC-37 or the Hep-2 cell lines. In three subjects lacking detectable antibodies at the 1:4 dilution of the sera, the administration of a dose of IPV produced after 5-7 days a high response which remained almost unchanged 30 days later
The educational background of the Top Managers of the Italian Health Authorities: results of a study on eight Regions.
No full textDopo circa un anno dall’entrata in vigore della nuova legge per la selezione dei Direttori Generali (DG) (D.Lgs. 171/2016), è stato condotto uno studio (dati aggiornati ad Aprile 2019) che ha indagato il background formativo dei DG recentemente nominati dalle Aziende Sanitarie Locali e Aziende Ospedaliere in Italia. Lo studio, ricalcando una ricerca analoga realizzata dall’Università Bocconi nel 2013, ha preso in considerazione 8 Regioni (Piemonte, Lombardia, Liguria, Umbria, Lazio, Basilicata, Sicilia, Sardegna), esaminando i curricula dei 112 DG recentemente nominati: l’età media è di 58,7 anni, con una percentuale di donne sorprendentemente bassa (16%). Circa la metà dei DG (50,5%) ha conseguito una laurea in Medicina e Chirurgia. Tra i DG non medici (49,5%), le lauree in Giurisprudenza (21) ed Economia (21) sono le più comuni. Tra i medici, 33 (58,9%) sono specialisti in Igiene e Medicina Preventiva, altri sono specializzati in diverse aree, principalmente cliniche. Complessivamente, i nostri dati sono coerenti con quelli registrati nel 2013 (eccetto un decremento dei laureati in Medicina -18,5%), confermando i diversi background formativi dei Manager della Sanità e il fatto che il background in Sanità Pubblica (acquisito nelle 35 Scuole di Igiene e Medicina Preventiva) rimane rilevante nelle carriere dirigenziali del Servizio Sanitario Nazionale italiano
