Sindrome delle apnee ostruttive notturne : sono sempre causa di non idoneità a mansioni complesse?
No full textThe author, after an analysis of the statistical data on work-related diseases reported to the INAIL and listed on the Annual Report 2007, examines the main highlights of the "new tables of professional diseases in industry and agriculture" published in the Ministerial Decree of July 21st, 2008 (GU n.169, 21-7-2008), also relating to the introduction of musculoskeletal disorders of the upper limb due to bio-mechanical strain into the list of professional diseases to which the legal presumption of origin is applicable
Respiratory allergy to nickel. Description of an atipical clinical case
No full textBACKGROUND: Exposure to nickel sulphate, other than contact dermatitis, can potentially cause respiratory symptoms. Although few cases of occupational rhinitis and asthma are reported in literature, a prolonged exposure can determine sensitization and evolution to respiratory symptoms. OBJECTIVES: Clinical evaluation of a case of occupational rhinitis and asthma due to nickel sulphate. METHODS: A female worker, aged 43 years, has been occupationally exposed to nickel for 22 years. After 1 year she experienced asthma, apparently not work related. She treated the respiratory symptoms for many years, but a slow and progressive increase of the disease was observed. During the last five years a straight relationship between work and symptoms was observed. On-off test was positive. The diagnosis of occupational respiratory disease was based on the work-related symptoms and the specific nasal challenge test result. RESULTS: An early response was observed with nasal symptoms (score 4), increase of anterior nasal airflow resistance (33%), severe dyspnea, haematic eosinophilia, and fall in FEV-1 of 18%. CONCLUSIONS: The prolonged exposure to nickel determined impairment of respiratory function. Nasal challenge, more safe and useful than bronchial challenge, can be considered gold standard for the diagnosis of occupational rhinitis and asthma due to occupational allergens
Consumo di alcool, idoneità complesse e responsabilità verso terzi: l'esperienza di una coorte di addetti al trasporto pubblico urbano. Alcol e lavoro: problematiche ed obblighi per il medico del lavoro
No full textBackground. The excessive intake or the abuse of alcoholic substances represent an important hazard's source for the individual health and for the carrying out of any complex working activities, above all if characterized by elevated responsibility toward other people.In this context the recent Provision of 16 March 2006 of the Permanent Lecture for the Relationships among the State the Regions and the Autonomous Provinces of Trento and Bolzano, has individualized bus driver among the activities or tasks of which is forbidden the assumption of alcoholic drinks at work and can performed alcoholic controls by the competent physician (art. 15 of the Law March 30 th 2001, n. 125). Within the normative considering the DM 23 February 1999 n. 88s (Rule bringing norms dealing about the check and the control of the physical and psycho-aptitude ability of the personnel employed to public transport services), we introduced experience growing up in the period from January 2005 to August 2006, on about 1500 employees, for over 90% of men, employed in a public transport company of the Lombardy as bus driver or railwayman. Methods. In order to assess driver's alcoholic abuse the analytical determination of carbohydrate-deficient transferring (CDT) has been used as a marker of alcohol intake. Within the visits of hiring in service (equal to 10% of the total one of the effected visits) the determination of the CDT has always been performed, while in revision visits (equal to 90% of the total one) this analytical determination has been performed only if possible alcohol abuse has been hypothesized by elevated values of gamma-GT before the Provision March 16th 2006 (and eventually of MCV, AST and ALT) and of routine from April 2006. Conclusions. This experience on this large population has confirmed the importance of a careful behaviours of abuse monitoring in workers with high responsibility toward other people. The CDT values reflect high alcoholic consumption, while is poorly remarkable the contribution furnished by anamnestic questionnaire
Evidence-based evaluation of the impact of medical directions in occupational medicine for professional workers driving buses, subways and other public transportation vehicles. 28th International Congress on Occupational Health
No full textIn this study we assessed the evidence of some specific, "ad hoc", medical indications for city bus, tram and subway professional drivers. As known, professional drivers have very little chances of modifying shift organization and many chronic degenerative diseases (low back pain, diabetes type 2, cardiovascular diseases, ecc.) are difficult to manage according to job planning. In our study we observed a positive association between introduction of specific shift, in particular when shift is divided in two-piece, on morning "turno spezzato 1°/1°" or one on morning and the second part on afternoon "turno binato 1°/2°". Evidence of the real impact on professional drivers health conditions has been found from analysis of sickness leave during two, or in same case, one year before and after such medical indications intoduction. In our occupational drivers cohort a positive association, evidence based on real rates of two years sick absence before and after medical indications, was found between improvement of health general conditions and reduction of sickness leave rates correlated
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
