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
Sentinel species selection for monitoring microplastic pollution: A review on one health approach
No full textNowadays, global environmental pollution is one of the most topical issues we have to deal with on a daily basis. Due to the development of the current society including industrial and agricultural areas, pollution and waste have increased dramatically in recent years. Among all contaminants spread worldwide, the increased use of plastic is probably the most evident. Nevertheless, plastic objects which are released into environmental compartments are processed into smaller units of plastic debris, defined, based on their dimensions, as micro- (MP) and nano-plastics (NP). These particles are classified as some of the most hazardous current micro-pollutants. The use of model organisms as bioindicators is one of the most effective ways to monitor and assess the occurrence of plastic particles in the environment.This review aims to provide comprehensive knowledge about the behaviour and the effects of MP/NPs particles on animals, humans, and the environment through the “One Health” concept, which provides an innovative and suitable perspective focused on the intersection of the above-mentioned three areas. Moreover, the key point is the evaluation of the most efficient bioindicators for monitoring microplastic pollution in environmental compartments, in order to better understand the importance of being more eco-friendly through the reduction of plastics objects.Whereas the earth is composed of about 70% water, a special focus is placed on aquatic ecosystems and the relative bioindicators. In addition, this collection of information highlights a common issue that requires awareness, prevention, and solutions to take care of global environments

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
