Environment, Occupation, and Chronic Maxillary Sinusitis in Pre-Roman Italy
No full textObjective: To assess the frequency of chronic maxillary sinusitis (CMS) in a pre-Roman archeological skeletal assemblage from Italy and to evaluate the occurrence of CMS in combination with its environmental and sociocultural context. Materials and methods: A total of 131 adult individuals from the pre-Roman site of Pontecagnano (eighth to third centuries bce) in southern Italy with intact maxillary sinuses of ≥ 50% preservation were macroscopically and microscopically observed for the presence of osseous changes per published diagnostic criteria of CMS. Results: CMS was present in 57.2% of individuals. The prevalence of CMS was higher in females than in males, and this difference was statistically significant (p = 0.043). The frequency of CMS increased with age-at-death. Bilateral CMS occurred more frequently than unilateral CMS. The differences in the prevalence of CMS in the Etruscan (700-450 bce), Samnite (450-375 bce), and final pre-Roman (375-200 bce) phases of occupation were not statistically significant. Discussion: In combination with viral and bacterial infections, occupational activities (metallurgy, ceramic and textile production, and agriculture) and environmental factors (volcanic ash, marshy environments, and sub-Saharan dust plumes) likely stimulated respiratory disease and resultant CMS in the inhabitants of Pontecagnano. This study provides a framework for future research on CMS and respiratory diseases in the Mediterranean region, in relation to environmental, climatic, and anthropogenic influences. The limited number of individuals per period prevented a proper diachronic analysis. Osteoarcheological assemblages from the Mediterranean region should be systematically analyzed for CMS to increase understanding of how climate, environment, industrialization, and urbanicity affected human health through time
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

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
