A document by the B. Ramazzini College of University Teachers of Occupational Medicine of the Italian Society of Occupational Health and Industrial Hygiene (S.I.M.L.I.I). The aim of this document was to compare the professional competence, training profile and core curricula of the three main specialization courses in the Public Health postgraduate medical area, i.e., Occupational Medicine, Hygiene and Preventive Medicine, and Forensic Medicine, such as contained in the Ministerial Decree (D.M) of 1 August 2005. We set out to identify, using clear and objective criteria, the knowledge and skills that specialists in Hygiene or Forensic Medicine must develop, in accordance with Art. 38 of the new Italian law on safety ahd health at work (D.Lgs 81/2008), in order to be authorized to perform occupational health activities as "Competent Physicians" (CP). The comparison revealed significant differences in structure and content among the three courses. In particular, compared to the course in Occupational Medicine, the courses in Hygiene and in Forensic Medicine both lack clinical training, including diagnostic and therapeutic skills, risk-oriented occupational health activities, biological monitoring, assessment of individual susceptibility, and clinical or instrumental procedures to prevent and detect occupational diseases. Furthermore, the specialization course in Hygiene lacks any training regarding the criteria and methods for assessing the individual worker's fitness for work, while the course in Forensic Medicine lacks any training in occupational risk assessment and management. From this comparison, a list was derived of the education and training debits that specialists in Hygiene or Forensic Medicine should cover (credits) in order to be authorized to perform CP activities as indicated by the new law. A core curriculum is proposed here, based on the corresponding credits, for use as a reference
The Effects of revascularization procedures on myocardial incidence rates and time trends: the MONICA-Brianza and CAMUNI MI registries in northern Italy.
No full texturpose: Clinical guidelines recommend early reperfusion treatment in myocardial infarction (MI) patients to reduce the cardiac damage. Epidemiologic definitions of MI are often based on the evolution of the cardiac lesion. We aim to study the effect of treatment on the estimates of rates and 20-year time trends of MI. Methods: A Multinational Monitoring of trends and determinants in Cardiovascular disease (MONICA) register was active between 1985 and 2004 to survey 35- to 64-year-old residents in Brianza, Northern Italy. To the well-established MONICA definite MI, we added the MONICA possible nonfatal MI receiving either myocardial revascularization or thrombolysis within 24 hours from onset. The average annual relative changes in incidence rate and 28-day case fatality percentage were estimated from log-linear models. Results: In our population, characterized by a monotonic decrease in coronary heart disease (CHD) mortality rates, the incident rate for the standard MONICA definite MI decreased yearly by 3% in both gender groups. The addition of selected revascularizations halved the downward trends in incidence rate in men and women; conversely, the decline in 28-day case fatality became steeper. Conclusions: From an epidemiologic perspective, the increasing proportion of acute events efficaciously treated with revascularization therapy affects the estimate and the interpretation of time trends in MI incidence and CHD mortality

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
