Studi sulla personalità dei pazienti glaucomatosi
Gli Autori hanno effettuato una ricerca bibliografica sullo stato della personalità dei pazienti glaucomatosi constatando che alcuni studiosi hanno stabilito delle tappe che debbono essere considerate fondamentali per chiarire gli aspetti "psicosomatici" del glaucoma
Comportamento del coefficiente di rigidità sclerale di occhi normali e glaucomatosi dopo somministrazione orale di glicerolo (Behaviour of the scleral rigidity coefficient in normal and glaucomatous eyes after oral administration of glycerol)
E' stata notata una modesta diminuzione del coefficiente di rigidità sclerale dopo somministrazione orale di glicerolo (g. 1/Kg) in soggetti normali ed in pazienti affetti da vari tipi di glaucoma. Tale modificazione non è sembrata essere significativa. Gli Autori fanno alcune considerazioni su tale fenomeno
Il comportamento dell’idrodinamica oculare in corso di trattamento con Epinefrina (Behaviour of ocular hydrodynamics in treatment with epinephrine)
Quattordici pazienti affetti in uno od entrambi gli occhi da glaucoma cronico ad angolo aperto sono stati trattati con Epinefrina al 2 per cento per tre volte al giorno. E' stata osservata una ipotensione oculare in tutti i pazienti trattati. Da un punto di vista idrodinamico avviene un significativo decremento della formazione dell'umor acqueo all'inizio della terapia. In seguito si è notato un progressivo incremento della fuoriuscita di esso. Sono state avanzate alcune considerazioni sulla azione della Epinefrin
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
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
