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
Quando e perché l’univocità del parere medico può aiutare la percezione dello stato di salute e del tono emotivo nel paziente oncologico
No full textIn many occasions, we are usually inclined to think that a deci- sion based on multiple (sources of) information may - or even must
- be “better” than a decision based on a single piece of information, or source. However, in certain psychological conditions - such as tho- se of oncological patients - decisions made on the basis of a single, clear-cut medical opinion, rather than on a multiplicity of even con- trasting medical views, should be maximally useful in satisfying pa- tients’“need for univocal views” and, in turn, also in fostering their sense of a positive emotional and physical condition. The present re- search, conduced with 40 oncological patients, was thus interested in establishing 1) in which proportion patients acquired “one-single” vs. “multiple” medical opinions while choosing among different treatment alternatives, and 2) the quality of patients’perception of their emotional and physical state. As hypothesized and then discussed on the basis of the Theory of Multiple Perspectives (TMP), results sup- ported the hypotheses, revealing a comparatively better perception of their emotional and physical state among patients who asked for just “one single” (univocal) medical opinion - thereby satisfying their “need for univocal views” - but not among patients asking for more than one single medical opinion, that is among patients using a strategy ostensibly at odds with the possibility of satisfying their psy- chological need for univocal, unambiguous views.mente si è portati a ritenere che una decisione basata su una molteplicità di informazioni e/o fonti possa, o addirittura debba, ri- velarsi “migliore” di una decisione basata su una sola informazio- ne o una sola fonte. Tuttavia, in condizioni psicologiche particolari, come quelle che caratterizzano il malato oncologico, decidere il pro- prio percorso di cura sulla base di un solo parere medico anziché sul- la base di più e molteplici pareri dovrebbe rivelarsi utile ad assecon- dare il “bisogno di univocità” del paziente oncologico e, di conse- guenza, favorirne pure la percezione di un miglior tono emotivo e sta- to di salute fisica. La ricerca, condotta con 40 pazienti oncologici, ha stabilito, innanzitutto, in che misura i pazienti avessero raccolto “un solo” (= univocità) oppure “più” (= molteplicità) pareri medici re- lativi alle proprie scelte di cura e, successivamente, la qualità del tono emotivo di ciascun paziente, assieme all’auto-percezione dello pro- prio stato di salute fisica. I risultati, ipotizzati e discussi alla luce del- la Teoria delle Prospettive Multiple (TPM), confermano appieno le previsioni, dimostrando la percezione di un miglior tono emotivo e di un migliore stato di salute fisica fra quei pazienti che avevano chie- sto un solo parere medico assecondando, con ciò, il proprio “biso- gno di univocità”, ma non fra i pazienti che avevano richiesto, inve- ce, più di un parere medico e, con ciò, disatteso - e nei fatti impedi- to - la soddisfazione di tale importante bisogno psicologic
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

No full textAppropriate 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
