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
Hollywood Stars’ Involvement in Aquatics and Water Safety
Get PDFThe aim of this educational review article was to identify cases of Hollywood stars who have been involved in aquatics. A literature search was conducted using the terms ‘drowning’, ‘Hollywood’, ‘actor’, rescue’, ‘aquatics’, ‘swimming’ and ‘lifeguard’. It was found that several Hollywood film stars (n = 33; males = 20, females = 13) have worked as lifeguards (n = 12), performed lifeguard rescues (n = 2), or lifesaving rescues (n = 4), were aquatics athletes (n = 6), or suffered drown-related incidents (n = 9). A brief overview of those actors and their involvement in aquatics is presented
World Art on Swimming
Get PDFThis article aims to identify swimming-related artwork from Paleolithic times up to the present day and to assess whether possible use of art could act as aid to teaching. An art search obtained 49 paintings and sculptures. Results confirmed that artists have bestowed a wealth of related artwork on the world of aquatics. Depictions of people swimming competitively or recreationally, diving, bathing, working and fighting were found in Egypt, Greece, Persia, Italy, Spain, the USA, Japan and China. Depending on the particular society, the ability to swim indicated either a high or low socio-economic status. In some depictions, knowledge of swimming was accompanied by the ability to dive from high cliffs or into deep water, to hold one’s breath underwater, and to show physical endurance. A variety of swimming strokes were depicted throughout history in art. Various types of swimwear, or nude swimming, were evident in different societies
Lifeguard Legislation in Greece
Get PDFLegislation dealing with lifeguards can have a major impact on all aspects of aquatic safety, including employers and employees, certifying organizations, local authorities and swimmers. The purpose of the present study was to critically evaluate legislation in Greece related to lifeguarding. Results show that although lifeguarding is by law mandatory, changes need to be made to focus on training and examination standards, the name and meaning of the lifeguard qualification, and the establishment and operation of lifeguard agencies and aquatic facilities
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
