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

No full textAppropriate 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
Data compression in dynamic systems
No full textData compression in dynamic systems has several applications in the real world. Unlike the compression of static data, both data and intrinsic data patterns may change over time. A good compression in dynamic systems should either keep compression accurate for dynamic data or change its compression strategies for dynamic data patterns. In this thesis, we study both scenarios with applications from the real world. First, as an example of compression in dynamic systems with changing data, we discuss a lossy compression in databases, called synopsis, which helps the query optimizer speed up the query process. We introduce new Haar wavelet synopsis for nonuniform accuracy and time-varying data that can be generated in near linear time and space, and updated in sublinear time. The effectiveness of our data synopsis is validated against other linear time methods by using both synthetic and real data sets. Second, as an example of compression in dynamic systems with changing data patterns, we propose a novel compression algorithm, called IPzip, which compresses IP network traffic both online and offline for efficient data transfer and storage. IPzip achieves better compression ratios by learning patterns residing in both data structures and content. We also propose a methodology to monitor over time the effectiveness of the current compression and start new pattern learning when intrinsic traffic structure changes. Finally, via trace-driven experiments on network traffic obtained from Tier-1 ISPs, we validate that IPzip achieves better performance compared to previous approaches.Ph.D.Includes bibliographical references (p. 80-83)
