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
A multi-scenario model for empty container repositioning under uncertain demand
No full textThis paper investigates the maritime repositioning of empty containers under uncertain demand. In order to consider data uncertainty, the problem is addressed by a stochastic programming approach, in which different scenarios are included in a multi-scenario optimization model and linked by non-anticipativity conditions. Numerical experiments show the benefits of multi-scenario solutions with respect to deterministic approaches, which consider only a single point forecast for each uncertain parameter
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

Valutazione della soddisfazione dei consumatori di vino sardo
No full textL’articolo illustra un’applicazione della Customer Satisfaction Analysis ai vini sardi ed è stata realizzata intervistando un campione di consumatori che si dichiarava consumatore di vino sardo. Oggetto dell’analisi è stata dunque la soddisfazione del pubblico per un’offerta aggregata che include tutti i vini riconoscibili come sardi, appartenenti quindi alle categorie igt, doc e docg, e realizzati da tutte le aziende che in Sardegna producono questi beni. Nella letteratura relativa ai vini non sono presenti studi di Customer Satisfaction Analysis, ma l’evoluzione del mercato del vino e la forte competizione tra vecchi e nuovi paesi produttori richiede nuovi strumenti in grado di individuare, anche attraverso le opinioni dei consumatori, politiche di marketing efficienti per le aziende e le istituzioni locali. Obiettivi dell’indagine sono stati la valutazione del grado di soddisfazione dei consumatori rispetto ai vini sardi in generale e rispetto ai diversi elementi dell’offerta e la comprensione di quali dei diversi elementi dell’offerta aziendale influenzano significativamente i processi di scelta e quindi il livello di consumo dei diversi vini. La ricerca è stata svolta attraverso l’approccio econometrico applicando un modello Ordered Probit. I risultati ottenuti provengono dall’applicazione del modello all’intero campione e a due differenti ripartizione dello stesso, al fine di individuare tra i diversi consumatori eventuali differenze nella valutazione della qualità. La ricerca mostra un livello di soddisfazione dei consumatori di vini sardi medio-alto, ma il consumo sembra essere determinato da pochissimi elementi tra i quali predominano gli elementi sensoriali. l’unidimensionalità della soddisfazione ed il suo non elevatissimo livello indicano una non stabile posizione nel mercato dell’offerta dei vini sardi
