Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Affrontare il divario generazionale tecnologico attraverso il gioco
No full textIl paper presenta la ricerca teorica alla base di uno strumento ludico pensato sia per produrre consapevolezza su ciò che il divario digitale comporta, sia per ridurlo. L’artefatto, chiamato [S]collegati, è un sistema di comunicazione capace di veicolare informazioni e stimolare al dialogo e alla collaborazione tra le generazioni, forte da un lato dei meccanismi motivazionali tipici del gioco, dall’altro dello spazio sicuro che lo contraddistingue e all’interno del quale si incentiva l’apertura al nuovo e al diverso. Attraverso le sue meccaniche, invita i giocatori a riflettere criticamente sulle proprie abitudini e sui propri atteggiamenti nei confronti della tecnologia e di internet. La progettazione, basata sulla letteratura che ha analizzato le problematiche proprie di ciascuna generazione, ha intesto produrre un artefatto ludico che invita i giocatori a fare esperienza diretta dei propri limiti tecnologici e delle proprie abilità, trasformando le differenze alla base del divario in occasioni di condivisione, scambio e miglioramento reciproco. Il paper propone una disamina del contesto teorico e tematico alla base della progettazione e conclude fornendo alcune interpretazioni preliminari di possibili usi da parte degli utenti sulla base di situazioni sperimentali osservate durante lo svolgimento del lavoro progettuale
Variations on the Author
Get PDF“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
Get PDFWe 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
Transcutaneous oxygen tension measurement in patients with chronic arterial obstructive disease: reliability and long term variability of the method
No full textAlthough transcutaneous oxygen tension (TcpO2) measurement may be useful for assessing changes in regional perfusion induced over time by drug or surgical treatment in patients with chronic arterial obstructive disease (CAOD), the reliability of the method over a long-term period is not know. To approach this problem, the authors evaluated retrospectively the behavior of TcpO2 measurement over time in patients with CAOD. To eliminate confounding influences due to the concomitant vascular disease at the limb level, data analysis was performed on TcpO2 measured at the right infraclavicular position. The median length of follow-up ranged from twenty days in 34 patients to 832 days in 3 patients (n = 2 and n = 10 individual sequential replications respectively). Initial and final TcpO2 values did not differ significantly even at the longest follow-up term, which indicates that the parameter is constant over time. The intrapatient variation coefficient of TcpO2 (calculated over at least three individual replications) ranged between an average of 11% to 16.2%. The corresponding interpatient variation fluctuated between 15.5% and 33.4%, a variability explained to some extent by sex-related influences, but, at least in the range of this sample, not by age, arterial oxygen levels, or disease status. Thus TcpO2 levels per se are stable, implying that TcpO2 measurement has the potential to record consistent changes caused by specific therapeutic interventions or the clinical evolution of patients with CAOD. However, the intrapatient and interpatient variability of the method has to be taken into account when TcpO2 is used for the follow-up and the physiopathologic study of patients with CAO
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
