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
Anomalous Seebeck coefficient in boron carbides
No full textBoron carbides exhibit an anomalously large Seebeck coefficient with a temperature coefficient that is characteristic of polaronic hopping between inequivalent sites. The inequivalence in the sites is associated with disorder in the solid. The temperature dependence of the Seebeck coefficient for materials prepared by different techniques provides insight into the nature of the disorder
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
Ahead of its Time: Dickens's Prescient Vision of the Arts
No full textDickens’s relationship with the Arts has confounded or silenced some of the most eminent critics from his day to ours. His own reticence on the topic likewise makes the idea of a book on Dickens and the Arts a little odd or dissonant. Though as this volume makes clear, he was well versed in a range of high and low arts, he was seemingly determined to embrace, if not the wrong side of the cultural track, metaphorically speaking, a different track. The Introduction is structured around four broad areas which are key to an understanding of both the ideological underpinnings of shifting definitions of the Arts, and to an understanding of the reasons for Dickens’s complex relationship to the idea of the Arts: money/materialism; hierarchies of privilege; yardsticks of criticism or artistic judgement; the public good. There is an uneasy relationship between ‘the Arts’ and all four areas, between Dickens and all four, and between Dickens and the Arts understood via these frames, which are commonly invoked in discussions of the Arts. The contention of this volume is that, far from being a philistine who had no interest in the Arts, Dickens’s apparent reticence in an industrial age where the value and function of the Arts was uniquely important in public debate, masks a complex and sophisticated vision (if not theory) of the Arts in the modern era, which is, and was, ahead of its time. Dickens’s philosophy of art in fact works to complicate in subtle ways the idea of an opposition between idealist and integrationist views of the aesthetic, though its most characteristic thrust is integrationist
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
