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
Caratteristiche del manico degli strumenti manuali: revisione della letteratura
No full textI disturbi muscolo-scheletrici di natura lavorativa (DMSL) hanno avuto negli ultimi due decenni un netto incremento di incidenza. Anche tra gli igienisti dentali il rischio di sviluppare un DSML è elevato e ad esserne più colpiti sono i professionisti anziani e di sesso femminile. La prevenzione dell’insorgenza di questi disturbi riveste un ruolo cruciale nel mantenimento delle capacità lavorative e richiede la precoce identificazione e la correzione dei fattori di rischio, suddivisibili in elementi connessi al lavoratore, al tipo di mansione, alla posizione di lavoro e allo strumentario utilizzato. Molti fattori di rischio possono essere minimizzati o eliminati grazie a prevenzione, strategie ergonomiche e programmi terapeutici mirati. La prevenzione è basata sull’analisi epidemiologica, su un’attenta valutazione dei sintomi, delle posture più comunemente assunte, dei gesti lavorativi e della strumentazione utilizzata. Scopo del nostro lavoro è stata una attenta revisione della letteratura riguardante la strumentazione con particolare attenzione al manico degli strumenti manuali usati dagli igienisti dentali. Dai lavori pubblicati non abbiamo rilevato alcuna indicazione che permetta agli operatori di operare una scelta ponderata tra i vari strumenti in rapporto alle caratteristiche fisiche dell’operatore con particolare riferimento alle dimensioni della mano lavorante. Da tale revisione risulta quindi evidente la necessità di ulteriori ricerche finalizzate alla identificazione di strumenti di forma, diametro e peso diversi in relazione alle tipologie fisiche degli operatori
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
Different susceptibility of local Apulian and Calabrian grapevines to downy mildew and characterization of Plasmopara viticola populations
No full textDowny mildew, a severe grapevine disease worldwide, is caused by different cryptic species of Plasmopara viticola. Several approaches are under study to reduce the impact of chemicals in the disease management, including the selection of resistant genotypes for grapevine breeding. In this study, the susceptibility of six different local wine grape cultivars was assessed on leaves and bunches, in 2023, an year particularly favourable to the downy mildew epidemy. Based on McKinney's index (MKI: 37.3 to 52.6%), Marchione, Moscato reale, Maresco and Moscato di Terracina were more susceptible than Moscato di Trani, Trebbiano and Verdeca, classified as resistant ones (MKI: never exceeding 16.6%). Additionally, the genetic variability of P. viticola populations infecting grapevine in Apulia, Calabria and Lombardia was evaluated. Sporangia were collected from oil-spots in 26 vineyards (15 Apulia, 11 Calabria), during 2023 and 2024 years. The CAPS analysis was carried on restriction enzyme AseI profiles of the amplified DNA using the ITS1-O/ITS2, according to Rouxell et al. (2013). A total of 130 isolates and 20 DNA samples from oil spots sampled in Lombardia were analysed. All belong to the clade aestivalis, as also confirmed by BLASTn analysis of the ITS partial sequence of few representative isolate of Apulia and Calabria regions. These preliminary results suggest that the resistant behaviour of analysed grapevine genotypes is limited to P. viticola clade aestivalis and highlight the opportunity to preserve the local biodiversity for possible introduction of new P. viticola clades, currently absent
