Sport per disabili: dalla riabilitazione alle Paralimpiadi.
No full textLa pratica regolare di esercizio fisico, cioè di attività motoria strutturata determina in soggetti con disabilità locomotoria, ed in particolare in soggetti con mielolesione (tetraplegici e paraplegici), effetti benefici sulla salute. Tali effetti salutari consistono nel miglioramento dell’efficienza cardiovascolare e respiratoria (con un ridotto rischio di incorrere in malattie conseguenti all’aterosclerosi), miglioramento della “fitness” muscolare (forza massima e capacità di protrarre l’esercizio a differenti livelli di contrazione sottomassimale) ed un generale miglioramento
della funzionalità motoria con conseguente maggiore autonomia e ridotto stress cardiocircolatorio nelle attività della vita quotidiana. Dagli anni ‘70 in poi, parallelamente al suo
uso di tipo fisiatrico, lo sport per i soggetti
disabili si è andato sempre più evolvendo,
acquistando popolarità e valenza agonistica
sempre maggiore tanto da potersi ora considerare,
in termini di spettacolo e di significato
sociale, alla stessa stregua dello sport per i
normodotati. Oggi le Paralimpiadi estive sono
considerate per importanza il secondo evento
sportivo al mondo (www.paralympic.org). Poichè la pratica sportiva non è però esente da rischi è fondamentale una accurata valutazione dello stato di salute degli atleti che raggiungono l'obbiettivo di gareggiare a livello paralimpico. sulla base di una ventennale esperienza iniziata con le visite paralimpiche di Seoul ‘88, frutto di una collaborazione tra la Scuola di Specializzazione in Medicina dello Sport dell’Università di Roma “Sapienza”, diretta dal Prof. Marco Marchetti, e la allora Federazione Italiana Sport Handicap, è stata messa a punto la visita di idoneità paralimpica
Umbilical metastases: current viewpoint
No full textAbstract Background Umbilical metastases from a malignant neoplasm, also termed Sister Mary Joseph's nodule, are not commonly reported in the English literature, and they have usually been considered as a sign of a poor prognosis for the patient. The present article reports on the current view point on umbilical metastasis besides discussing the epidemiology, clinical presentation, pathophysiology and treatment. Method A search of Pubmed was carried out using the term 'umblic*' and 'metastases' or metastasis' revealed no references. Another search was made using the term "Sister Joseph's nodule" or sister Joseph nodule" that revealed 99 references. Of these there were 14 review articles, however when the search was limited to English language it yielded only 20 articles. Articles selected from these form the basis of this report along with cross references. Results The primary lesions usually arise from gastrointestinal or genitourinary tract malignancies and may be the presenting symptom or sign of a primary tumour in an unknown site. Conclusion A careful evaluation of all umbilical lesions, including an early biopsy if appropriate, is recommended. Recent studies suggest an aggressive surgical approach combined with chemotherapy for such patients may improve survival.</p

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
