Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Tracer-Derived Measurements of Coarse Clastic Sediment behaviour, in the Littoral Zone
No full textThree aspects of coarse sediment movement of importance in coastal protection are: differential transport; vertical mixing and the rate of longshore transport. Within the present contribution state of the art tracer methods are used to improve understanding in these key subject areas.The analyses conducted show that longshore travel distance is intermittently related to particle size and position (cross-shore and vertical) on a beach. Particle size and shape are intermittently related to cross-shore transport, and size, shape and position (cross-shore) are related to vertical movement. The strongest evidence, to date is presented for the existence of secondary sorting. No clear evidence is found that factors are preferentially correlated with cumulative distance travelled relative to distance travelled per tide.The first measurements of sediment mixing depth on an engineered beach show that the thickness of the moving sediment is related to significant wave height, as is the case for open beaches. The relationship identified actually agrees very closely with that for the adjacent open beach, and with that for an open beach at another site (Charmouth, UK) which has a broadly similar grain size.Analysis of longshore transport rate data, indicates that drift efficiency (K) does not increase in value with increasing wave energy. The K values presented are, however, the highest found to date. The use of high quality wave and tracer data and/or inadequate tracer mixing are identified as possible causes of the unusual results. The first quantitative investigation of the degree of tracer incorporation confirms that mixing with the indigenous material was not complete and hence is a source of error. Longshore transport rate measurements are compared for open and engineered sections of the same beach. Drift efficiency is found to be higher on the open beach (K=0.853) than the engineered beach (K=0.534).A review of tracer theory is undertaken. Literature on the subject is found to be limited and heavily reliant on models, nevertheless, it casts doubt on the validity of the methods used in all tracer based determination of longshore (shingle) transport to date - a fact not recognised or discussed by previous authors.</p
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
