Il senso dell'udito nel Corpus Aristotelicum
Full text linkThe research that I have carried out on the sense of hearing in the Aristotelian ambit is based on a personal interest in the medical aspects that can be found in the treaties of the Stagirite.
If, on the one hand, there has always been very deep attention by the scholars to the phenomenon of perception, and still there is, on the other hand, although not ignored, hearing remains perhaps somewhat neglected or, however, not sufficiently investigated so far, despite its importance; but, above all, the effort to consider all its various implications together and the whole Corpus Aristotelicum has not been accomplished up to today. This is the intent that I have purposed and which I hope to have at least partially achieved.
Of course, it was a constant need to refer also to the other senses and, in general, to Aristotle's theory of perception; I have, however, tried to point out every possible aspects, which could explain the peculiarities of hearing.
Without claiming in any way to draw up a rank list of the senses, since each of them, according to the different points of view, seems more or less to aspire to a kind of primacy, I was able to demonstrate the extraordinary importance of hearing and, within certain limits, his preferability. After an introductory chapter on the position of hearing among the other senses, I have proposed a rather long one, in which I more specifically dealt with the anatomical, physiological and pathological aspects (and, finally, even some physical-mathematical considerations, that I think of great philosophical and scientific relevance); then, it has been given ample space (and could not be otherwise) to the complex issue of the relationship between hearing and language, which made it possible to highlight, thanks to the comparative approach of the Aristotelian investigations in the biological ambit, the differences between sound, voice and speech, and to show the key role of hearing in order to learning (also animal) and intellectual development (especially human).
In a final articulated chapter I approached what I consider the further possible implications of hearing, always clinging to the Aristotelian treatment: in addition to the physical phenomena of echo, roar, resonance and the psychophysicist ones of acoustic illusions, I could not exempt myself from talking about music, also in "technical" terms (as my limited skills in the field have allowed me to), but especially because of its educational features examined in the paragraph Emotions, morality and education, where hearing is reported as undisputed protagonist in the ethical, aesthetic, rhetorical, political ambits; the chapter, and the dissertation itself, are closed by some remarks about the relations of hearing with memory and recollection and with dream: apart from the latter, where sight seems to dominate, with the first two the auditory role is on the contrary of primary importance, despite still today people are often inclined to mention visual memory more frequently.
Even from these few notes I think I can state that it was really worthwhile to dedicate a research to the sense of hearing, especially in regard to a Corpus so broad, rich, varied and complex, such as the Aristotelian one
Location of Gliomas in Relation to Mobile Telephone Use: A Case-Case and Case-Specular Analysis
No full textThe energy absorbed from the radio-frequency fields of mobile telephones depends strongly on distance from the source. The authors' objective in this study was to evaluate whether gliomas occur preferentially in the areas of the brain having the highest radio-frequency exposure. The authors used 2 approaches: In a case-case analysis, tumor locations were compared with varying exposure levels; in a case-specular analysis, a hypothetical reference location was assigned for each glioma, and the distances from the actual and specular locations to the handset were compared. The study included 888 gliomas from 7 European countries (2000-2004), with tumor midpoints defined on a 3-dimensional grid based on radiologic images. The case-case analyses were carried out using unconditional logistic regression, whereas in the case-specular analysis, conditional logistic regression was used. In the case-case analyses, tumors were located closest to the source of exposure among never-regular and contralateral users, but not statistically significantly. In the case-specular analysis, the mean distances between exposure source and location were similar for cases and speculars. These results do not suggest that gliomas in mobile phone users are preferentially located in the parts of the brain with the highest radio-frequency fields from mobile phones

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
