Dedicated to my parents,
No full textMy very special thanks go to my advisor Gustavo de Veciana. Gustavo is a truly exceptional teacher, researcher and a very dedicated guide to (not only his) students. I consider myself very lucky in that I had an opportunity to collaborate with Gustavo throughout my PhD re-search, since the main theme and directions of this thesis were inspired through many fruitful discussions that we had since I joined Gustavo’s group. I thank all faculty members within the Department of Electrical Engineering for their constant help and support throughout my PhD studies. In particular, many thanks to professor Ari Arapostathis who is responsible for over fifty percent of my knowledge within the area of applied probability – I have taken more classes with him than with any other professor here in the University of Texas at Austin. I owe my knowledge within the areas of networking and op-timization to professors Ross Baldick, Sanjay Shakkottai, Scott Nettles and Alan Bovik – these are excellent teachers and I enjoyed their classes immensely. I am also grateful to professors Jeff Andrews, Robert Heath and all members of the Wireless Networking and Communication Group, who played a significant role in attracting me to the field of wireless networking and helped to further and deepen my knowledge within the field. Thanks also to all members of m
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

No full textI would like to thank all of the people who helped me complete this challenging journey. The completion of my dissertation would not have been possible without the encouragement and support of my family, especially my wife, and children. This accomplishment would also not have been possible without my wonderfully caring parents and the great teachers I have had along the way, from elementary through high school, and at the university level. They gave me the skills, confidence and inspiration that have enabled me to keep pursuing my goals. It has been a great honor to learn and research with my two advisors Prof. Thomas Edgar and Prof. Robert Flake. Their outstanding teaching skills and extraordinary subject matter expertise have made the difference for me and my research. Prof. Joe Qin contributed greatly to my research by continually supplying challenges and inspiration. I would like to thank the outstanding Professors Joydeep Ghosh, Ari Arapostathis and Glenn Masada for also serving on my thesis committee. During the last decade I had the fortune to be mentored by many talented engineers with brilliant personalities such as Terry Blevins, Dennis Stevenson, Willy Wojsznis, Greg McMillan, Mark Nixon, John Gudaz, Ken Beoughter, Mike Apel
