Lightcurve and Rotation Period Determination for 2496 Fernandus, 2727 Paton, and 69971 Tanzi
Photometric observations of the main-belt asteroids 2496 Fernandus, 2727 Paton, and 69971 Tanzi were made by the authors from 2019 January 3 to April 5. Analysis found bimodal lightcurves for each one. The most likely synodic periods are: 2496 Fernandus, 2.807 ± 0.001 h; 2727 Paton, 5.324 ± 0.001 h; and 69971 Tanzi, 32.540 ± 0.009 h
Rotation Period Determination of the Asteroid 5321 Jagras (1985 VN)
Photometric observations were made in 2018 of the main-belt asteroid 5321 Jagras (1985 VN). Analysis of the collected data suggests a period of 2.638 ± 0.001 h
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Il ruolo degli intermediari e i rischi finanziari
Il capitolo indaga le ragioni economiche che giustificano, per talune categorie di soggetti, siano essi datori piuttosto che prenditori di fondi, il ricorso all’opera di intermediari finanziari. In particolare, il capitolo illustra, alla luce dei rischi connessi allo scambio di fondi, il perché dell’esistenza degli intermediari di tipo sia asset broker sia asset transformer sulla base dei vantaggi che tali categorie di operatori offrono ai soggetti in avanzo e in disavanzo rispetto ai circuiti di mercato o, meglio, a completamento e integrazione dell’azione del canale diretto. In questa logica si vedrà come le banche definiscono una categoria peculiare e unica di intermediari finanziari
È possibile parlare di un’estetica bettiana?
Nella Teoria generale della interpretazione tante sono le questioni di rilevanza estetica che inducono a individuare al suo interno veri e propri percorsi estetici. Nel rivendicare questa tesi, dopo alcune osservazioni generali, il saggio prende in considerazione il modo in cui Betti tematizza il problema della creazione artistica. Tale questione, a cui nella Teoria generale della interpretazione è dedicata un’attenzione particolare, mostra da un lato la ricchezza della teorizzazione bettiana e, dall’altro lato, una comunanza di discorso con il pensiero estetico italiano coevo. Nonostante tale comunanza, il dialogo tuttavia non sbocciò. Ad alcuni punti problematici della mancata ricezione del pensiero estetico bettiano sono dedicate le considerazioni conclusive
Variations on the Author
“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
We 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
We 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
