[Effects on mortality and morbidity among the population living close to the Valmadrera (Lombardy Region, Northern Italy) incinerator]
No full textObjectives: assessment of the health effects on the resident population around the incinerator for municipal solid waste in Valmadrera (Lombardy Region, Northern Italy) in relation to the exposure level to the pollutants produced by the plant. Design: historical cohort study, based on the resident population from 2003 to 2016 in the study area. With a dispersion model, based on PM10 emitted by the plant, three areas of exposure (high, medium, low) were defined and, on the basis of the residence of the cohort, different exposure levels were attributed to the subjects. The association between level of exposure and health effects were estimated by comparing the high and medium exposure levels with the low exposure level, using a Cox model, adjusted for age and socioeconomic deprivation index. Main outcome measures: mortality rates, hospitalization rates, cancer incidence rates, and perinatal outcomes were analysed for the main causes potentially associated with exposure to incineration plants. Results: the subjects enrolled in the cohort were 106,056 (1,000,242 person-years). There were no statistically significant excesses of risk for almost all the outcomes investigated. Excessive mortality and hospitalization were found for liver/biliary cancers (HR women: 2.57; 95%CI 1.15-2.79; HR men: 2.22; 95%CI 1.10-4, 84). In the municipality where the plant is located, an excess prevalence (OR 1.78; 95%CI 1.43-2.21) of hepatitis C was found. Conclusions: the results suggest the absence of a relationship between residence in areas with different levels of pollutants emitted by the plant and the onset of almost all diseases. The associated causes do not have aetiological plausibility with exposure to pollutants from waste incineration. In particular, for liver/liver and biliary cancer, the association with infectious causes rather than exposure to environmental pollutants is more plausible

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
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
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
