Influence of posture on swallowing
No full textAim: This study investigates the relationship between posture disorders and swallowing, either of infantile type or affected by the presence of a short lingual frenulum. Materials and methods: The stabilometry examinations, taking into account the Romberg index and the LFS value, and when needed a frenectomy, showed positive variations in the recovery of a proper posture. The data were analysed by means of the Wilcoxon signed-rank test. Results and conclusion: This study showed that swallowing is able to modulate postural control and it can be a determining factor in postural syndromes that, if not promptly intercepted, may evolve into full-blown and irreversible musculoskeletal disorders for which treatment often proves ineffective
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
Asymptotics for Ginzburg-Landau energies in 3-D condensed matter physics
No full textThis paper is a rather informal survey on some recent results, presented at SIMAI 2010, on the asymptotic behavior of Ginzburg-Landau energies describing 3-D superconductivity and Bose-Einstein condensation in critical regimes where vortex nucleation occurs. As an application we rigorously derive an asymptotic expression for the relevant thresholds (respectively, the first critical magnetic field for type II superconductivity and
the critical angular velocity for rotating Bose-Einstein condensates) and the curvature equation for vortices. The analysis rely on Gamma-convergence techniques. A complete description of the theory sketched here, together with the proofs, is given in forthcoming papers
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
