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
Methodological critical issues for the assessment of the environmental impacts from transport of marble; a case study
No full textThe marble mining is very important for the Italian economy and has important traditions, especially in some areas of the Country. Among these, the area of the Dolomites in Val Venosta, located in Trentino, one of the North-East italian regions. In many cases, these quarries are very old and often are located in areas with high natural value. This work regards two quarries, which are located within an important national park. The need to reduce the environmental effects related to the traffic of trucks used for the transport of marble from the quarries to the processing plants, has led us to make assessments on the methodology to be applied. This paper presents the methodological approach identified to determine the best technical solution among several alternatives regarding the transport of marble. The validation of the methodology has its natural outlet in the application of a real case
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
A contribution to the evolution of the BAT concept in the steelmaking sector
No full textThe sector of steelmaking, in the European Union, is considered today one of the major potential contributors to the atmospheric release and consequent deposition of dioxin. The emissions of a plant depend on many factors: characteristics of the input, process, prevention and removal of dioxin from the gaseous stream. The local impact depends also on the different emission path, namely diffused emissions, secondary emissions and conveyed gases, as each stream can be related to a different way of dilution into the atmosphere. Moreover, the local impact is also related to the meteorological conditions. The high variability of parameters that can affect the local impact from a plant can be analyzed through the deployment of deposimeters, in order to understand the human exposure in the surroundings. The present paper refers to an Italian case-study where deposition was measured using deposimeters placed in sites identified by means of the results of a dispersion model. The role of particulate matter emissions was studied also with an optical particle counter. The obtained values are discussed taking into account seasonality and operation of the plant. Some considerations on the potential evolution of this industrial sector beyond the present concept of best available technology are included too
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
