The Perceptual - Motor Function
No full textIn the light of the new scientific findings, human movement cannot be understood or studied, without taking into account the perceptual processes and their role over cognitive integration in the action understanding and organization. Starting from the Theory of the Functional System up to the recent concept of the Mirror Neuron System, it has been understood how the Perceptual-Motor Function is intimately linked to cortical areas, classically understood as responsible for other functions. In particular, in the last few years, the role that the Broca's Area plays in the understanding of the action, and therefore in the organization of the Perceptual-Motor Function, is getting increasingly clear. In this perspective, the recent scientific literature focuses on investigating the use of specific verbal instructions as a key element in the learning of motor action
Funzione motoria e cognitività: dalla mente al movimento
No full textFunzione motoria, funzione cognitiva e mente rappresentano tre aspetti del cervello le cui reciproche relazioni consentono di ricostruire un triangolo che può essere letto mediante l’adozione di differenti chiavi interpretative. Scopo del nostro contributo è analizzare le caratteristiche della relazione tra questi tre elementi, mettendo in risalto in che modo ciascuno di essi è in grado di determinare lo sviluppo ed il funzionamento dell’altro in una modalità di rapporto che nella circolarità ritrova uno elemento di sviluppo che sotto molto aspetti caratterizza la specie umana. In altre parole, verrà preso in esame in che modo nell’uomo, nel corso nell’evoluzione, il movimento, da funzione meramente meccanica, ha assunto un ruolo estremamente importate nello sviluppo delle funzioni cognitive e come entrambi, verosimilmente, sono stati determinanti nella comparsa di quello che noi chiamiamo mente, la cui presenza distingue l’uomo da tutti gli altri esseri viventi
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
