THE ETYMOLOGY OF SILVIA
Leopardi approaches again and again, in his Zibaldone, the question about the historical relationship between Latin s° and Greek harsh spirit. He maintains, at the beginning, the antiquity of the Greek forms, but, almost suddenly, in January the 5th, 1822, he reaches the correct conclu- sion, that is, the priority of s°. This conclusion is attained thanks to a con- sideration of the examples he found in an article by Alexander Hamilton, partially translated in an Italian revue (in possession of Leopardi’s house), which supplied a series of lexical correspondences between Sanskrit and other languages in the perspective of a pioneering “Indo-European” linguis- tics. Going on autonomously, Leopardi observes the agreement between Latin and Sanskrit (e.g. Lat. septem ~ Skt. sapta) against the corresponding Greek form (e.g. ἑπτά – the latter not supplied by Hamilton) and, on the grounds of the application (for the first time in the Indo-European linguis- tics!), of the «rule of lateral areas», inferred a s° prior to Greek harsh spirit. An example, in this connection (dear to Leopardi even before this discovery), was Gr. ὕλη ~ Lat. silva: now, it is the s° in silva the demon- strably primeval one – that sound so many repeated, in a lot of alliterations, later on, in the verses of A Silvia

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
Role of proline 193 in the insulin receptor post-translational processing
No full textAims/hypothesis. A point mutation, P193L, in the insulin receptor alpha subunit, has been previously identified in a patient affected by an extreme form of insulin resistance due to reduced insulin binding. In our study we investigated the cellular mechanisms by which P193L substitution causes a reduction of insulin receptor numbers on the cell surface.Methods. Mutated insulin receptors have been generated and expressed in COS1 cells. Transcription as well as translation of P193L insulin receptor have been measured and compared with wild type insulin receptorResults. P193L insulin receptor is normally transcribed and progresses to the step of insulin proreceptor, which does not proceed to dimerization, resulting in the accumulation of the 210 kDa form. These findings suggest that the P193L insulin proreceptor is retained in the endoplasmic reticulum, where several molecular chaperones drive the folding of protein precursors. Therefore the interaction between mutated insulin receptor precursor and two endoplasmic reticulum resident chaperones (GRP78 and calnexin) were investigated. P193L insulin proreceptor co-immunoprecipitates with greater amounts of GRP78 and its interaction with calnexin is greatly delayed compared with wild type insulin receptor precursor, Co-transfection of wild type and mutated insulin receptors causes a considerable reduction of cell surface wild type insulin receptors,Conclusion/interpretation. P193 is critical for insulin propeceptor folding. The monomeric form of P193L insulin proreceptor is retained in the endoplasmic reticulum by a calnexin and GRP78 mediated mechanism that reduces mature insulin receptor expression on the cell surface
