il padel
No full textLa disciplina del “padel”, nata in Messico negli anni 70, sta riscuotendo anche in Italia una sempre più ampia popolarità; nel mondo ci sono oltre 6 milioni di giocatori e dall’aprile 2008 questa attività è stata riconosciuta dal CONI ed inserita nella Federazione Italiana Tennis.
Il padel è un gioco divertente al quale possono partecipare persone di diversa età, sesso, condizioni tecniche e fisiche.
Con la pubblicazione di questo lavoro, la Redazione si augura di fornire ai lettori un utile spunto di approfondimento e riflessione su questa interessante e moderna disciplina sportiva

The kitesurf | [Il kitesurf]
No full textLa rubrica “Medicina dello Sport per Sport” dedica questo numero al kitesurf, una delle nuove discipline praticata sulle spiagge che unisce il surf sulle onde con il volteggio dell’aquilone. Iniziata come momento di svago e di avvicinamento agli elementi della natura, è, da qualche tempo, una vera disciplina sportiva in voga con la prospettiva di presentarsi allo scenario olimpico
Intra- and Inter- day Reliability of Spine Rasterstereography
No full textTo determine intra- and inter-day reliability of spine rasterstereographic system Formetric 4D with and without reflective markers. 26 healthy volunteers (M group) had two markers placed in correspondence of vertebra prominens and intergluteal cleft, and 24 volunteers (NM group) were assessed without markers. All participants were analyzed two times in the same day and one time on a separate day. Trunk length, kyphotic angle, lordotic angle, pelvic inclination, kyphotic and lordotic apex, right and left lateral deviation, Flèche cervicale and lombaire, trunk imbalance, pelvic tilt, inflection point, rotation correction, right and left surface rotation, pelvic torsion, trunk torsion were measured. Intraclass correlation coefficient (ICC) and Cronbach Alpha (Cα) were calculated. In M group, for intra-, inter-day, and overall evaluations the higher reliability coefficients were 0.971, 0.963, 0.958 (ICC) and 0.987, 0.983, 0.985 (Cα) for trunk length, kyphotic angle and lordotic apex respectively; while in NM group were 0.978, 0.982, 0.972 and 0.989, 0.991, 0.991 for trunk length. In M group the lower values were 0. 598, 0.515, 0.534 (ICC) and 0.742, 0.682, 0.784 (Cα) for trunk and pelvic torsion, in NM group 0.561, 0.537, 0.461 and 0.731, 0.695, 0.729 for left lateral deviation. The reliability of most parameters was excellent
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
