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
Impacts of climate change on viticulture in Argentina
No full textClimate change is expected to impact considerably on viticultural zoning. In this work, impacts of future climate on Argentinean winegrowing regions are assessed using climatic projections from the IPSL-CM5A-MR model for the near (2015–2039) and the far (2075–2099) future under two emission scenarios (RCP4.5, RCP8.5). Four bioclimatic indices were assessed for exploring possible geographical shifts and suitability changes of Argentinean winegrowing regions. These geographical and suitability changes, assessed in terms of changes in vineyards location, varieties selection, and quality and quantity of grapevines, were considered as challenges and/or opportunities depending on the winegrowing region, the temporal horizon and the emission scenario. Results show a significant southwestward and higher altitude displacement of winegrowing regions, mainly for 2075–2099 under RCP8.5 scenario. Accordingly, the Argentinean viticulture may face both opportunities and/or challenges due to projected warmer climate conditions. Winegrowing regions of cold climates could be favoured, while winegrowing regions of warm climates could be disadvantaged, mainly for 2075–2099 under RCP8.5. Therefore, warmer climate conditions might be beneficial for maintaining the current grapevine varieties with their current grape quality or for cultivating new grapevine varieties in the new projected winegrowing areas; or they might be harmful for maintaining the current grapevine varieties with their yields and quality over most of current grapevine growing areas, but especially in the projected warmest ones. Summarizing, the results allow for understanding how temperature and precipitation changes could affect the future geographical distribution of Argentinean winegrowing areas and their suitability characteristics, useful information for planning adaptation in the coming decades.Fil: Cabre, Maria Fernanda.

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
