Microtrauma radial thrombosis
No full textThe articles describes a case of radial artery thrombosis by repeated microtrauma. It describes, by one side, the occupational history, the personal habits and the typical movement and condition of the hands while working, on the other, the clinical and diagnostic picture of radial artery thrombosis. Then it shows the correlation between occupational factors and radial artery thrombosis and so the occupational genesis (repetitive microtrauma) of the disease
Different case definitions to describe the prevalence of occupational carpal tunnel syndrome in meat industry workers
No full textObjectives: The aim of this study was to assess the prevalence of carpal tunnel syndrome (CTS) in a group of meat industry workers, using typical symptoms, median nerve conduction studies (NCSs) and their combinations. In the case definition including the NCSs, we tested the electrodiagnostic reference values derived from the general healthy population and from the asymptomatic study population. Methods: One-hundred fourteen workers were examined by clinical interviews and median NCSs. Results: The prevalence of CTS varied from 11% to 53%, with a progressive reduction passing from symptoms to NCSs to the their combinations. The prevalence was identical and the highest at the same time (53%) considering the case definitions based only on the symptoms and only on the NCSs with Kimura's reference values. Using the asymptomatic workers' electrodiagnostic reference values, alone or in combination with symptoms, the prevalence of CTS was the lowest (respectively, 15% and 11%). Conclusions: In the epidemiological studies, median NCSs should be considered desirable, if not essential, for confirming a clinical diagnosis, most of all in the longitudinal studies. In the future of CTS diagnosis, attention should be paid to the electrodiagnostic reference values that are discriminating to confirm the presence or not of the disease
Levels of agreement of nerve conduction studies and symptoms in workers at risk of carpal tunnel syndrome

No full textThe aim of this study was to assess whether a sample of 37 anaesthetists occupationally exposed only to N2O showed any deterioration in vigilance and/or mood. The anaesthetists were examined with three neurobehavioural tests (Simple Reaction Time and Colour Word Vigilance to measure the vigilance and Mood Rating Scale to evaluate the level of stress and arousal) and underwent N2O biological monitoring (to correlate the test results with the N2O exposure) on the first and on the last day of the work week, before and after work in the operating room. No significant relationship was found between the biological monitoring and the test results. The only significant statistical difference was found between the beginning and the end of each workday in the arousal level, regardless of the result of the biological monitoring
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
