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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
FIR filter synthesis using the adaptive RLS algorithm
Get PDFThis project compares and contrasts computer program implementations of the traditional adaptive LMS FIR lowpass filter synthesis and a new adaptive RLS FIR lowpass filter synthesis method developed by the author. A performance comparison for the RLS and LMS algorithms is presented. Examples comparing the adaptation rate and the frequency response for several different filter lengths are included. Implementation issues are also discussed, including the effects of iteration count, numerical precision, and computational complexity. The comparison suggests that the RLS algorithm provides slightly better error performance at the cost of additional computational complexity.Includes bibliographical references (leaves 75-76)California State University, Northridge.

Aari concept system : Linux powered mini computer
No full textThis project grew out of a desire to create tool that would be used personally by the author. The result is the aari Concept System. The aari system is a fully featured personal computer. Powered by the BeagleBoard, the aari system also features an FPGA-based expansion board that contains an Ethernet MAC controller. Bringing the aari system together, is a custom built Operating System using Linux kernel. aari is built with openness in mind and which is reflected in all aspects of its design
Software defined radio
No full textIncludes bibliographical references (leaf 36)Software Defined Radio is a communication system that utilizes software to implement communication functions that are typically done by hardware. Software implementations are often desired since it is less costly, and easily altered to meet different needs and requirements. In Telecommunication breakdown: Concepts of Communication Transmitted via Software-Defined Radio, the author explores the concepts of a software based radio in Matlab. At the end of the book, he leaves six text message files that have been coded, upconverted, sampled, and transmitted for the reader to recover. This software defined radio project will work to recover the author's message by constructing a software based receiver in Matlab
