High-level theoretical rovibrational spectroscopy of HCS+ isotopologues
No full textIn this work the rovibrational spectrum of the HCS+ molecular cation is revisited through high-level electronic structure and variational rovibrational calculations. A local potential energy function is built from explicitly correlated coupled-cluster results, incorporating corrections for core-valence, scalar relativistic and higher-order excitation effects. The computed spectroscopic parameters, based on variational calculations with Watson's isomorphic Hamiltonian for linear molecules lead to a nearly perfect agreement with experimentally reported values (Rosenbaum et al., 1989). Furthermore, the documented Fermi resonance within the (0, 0 degrees,1)/(0, 2 degrees, 0) and (1, 0 degrees,1)/(1, 2 degrees, 0) pairs of states is clarified. Based on a newly developed electric dipole moment function transition dipole moments of fundamental transitions are predicted for the most important isotopologues. (C) 2016 Elsevier Inc.

Pareyson's Role in Twentieth-Century Italian Aesthetics
No full textIl saggio si concentra sul ruolo giocato dall’estetica di Luigi Pareyson (1918-1991) nell’estetica italiana del ventesimo secolo. L’opera principale di Pareyson in questo ambito, Estetica. Teoria della formatività è la prima estetica sistematica scritta da un punto di vista radicalmente non-crociano che sia apparsa in Italia, e ha costituito un punto di svolta nella filosofia italiana del secolo passato, marcatamente influenzata nei primi cinquant’anni dal Neoidealismo e dallo Storicismo crociani. Dopo la Seconda Guerra mondiale molti filosofi italiani (per esempio Galvano della Volpe, Gillo Dorfles, Luciano Anceschi), si sforzarono di elaborare una filosofia dell’arte che potesse rimpiazzare l’estetica crociana, assai influente anche nella critica letteraria. Ma nessuno di loro produsse un’estetica sistematica, mentre coloro che lo fecero, come Cesare Brandi o Guido Calogero, non si mossero su di un piano del tutto indipendente da Croce.
La prima parte del saggio si sofferma sulle principali differenze tra le vedute di Pareyson e di Croce in materia di estetica, sottolineando in primo luogo le diverse soluzioni date al problema della natura dell’attività artistica (secondo Croce l’estetica è un’attività teoretica, una forma di conoscenza, mentre per Pareyson la sua essenza è di natura pratica, è una forma di fare che implica necessariamente la manipolazione di una materia), e poi le differenti vedute in tema di emozioni artistiche, di interpretazione, di rapporto tra estetica e poetiche. La seconda parte del saggio ricostruisce invece l’influsso dell’estetica di Pareyson sulla filosofia italiana della seconda metà del Novecento, mostrando come, non ostante il grande successo dell’Ermeneutica, l’estetica di Pareyson (che pure costituisce una componente essenziale della sua teoria dell’interpretazione) non abbia avuto il riconoscimento che avrebbe meritato. Nondimeno, alcuni tra i più importanti filosofi italiani della seconda metà del Ventesimo secolo, come Umberto Eco e Gianni Vattimo, sono stati profondamente influenzati dall’estetica di Pareyson.
ENGLISH
This paper focusses the role Luigi Pareyson’s Aesthetics played in Italian Philosophy of the twentieth Century. Estetica. Teoria della Formatività, Pareyson’s chief work in this field, represents the first systematic aesthetic theory written in Italy from an utterly non-Crocean view, marking a notable turning-point in Italian Philosophy of the last Century, deeply influenced in the first fifty years by Croce’s new Idealism and Historicism. Indeed, after the second world war many philosophers in Italy (e.g. Galvano della Volpe, Gillo Dorfles, Luciano Anceschi) tried to elaborate an aesthetic theory which could replace Croce’s philosophy of Art, very effective also in the field of literary criticism. But no one succeeded in creating a systematic aesthetics, embracing all the principal problems of the discipline, while those who wrote a systematic aesthetic theory in the Forties and Fifties, like Cesare Brandi or Guido Calogero, were not so completely independent from Croce’s philosophy.
The first part of the essay gives an account of the main differences between Pareyson’s and Croce’s views on Aesthetics, stressing firstly the different solutions concerning the nature of aesthetic activity (aesthetics, according to Croce, belongs to theoretical philosophy, being a kind of knowing, while for Pareyson Art is practical in its essence, as a kind of making which implies necessarily the shaping of a material), and then the different views concerning the role of emotions in art, the function of interpretation, the relationships between philosophic aesthetics and poetics. The second part of the essay is devoted to reconstruct the influence of Pareyson’s Aesthetics on Italian philosophy of the second half of the twentieth Century, showing how, the great international success of Hermeneutics notwithstanding, the importance of Pareyson’s aesthetics (a very notable constituent of his interpretation theory) was not entirely acknowledged. Nevertheless, some of the most important Italian philosophers of the second half of twentieth century, such as Gianni Vattimo or Umberto Eco, received weighty suggestions from Pareyson’s theory of art
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
