A Visual Evolution Explorer Visualize a Release History Database
No full textI would like to thank all the people who have supported me and have contributed directly or indirectly to the success of this thesis. Special thanks go to Professor Harald Gall for giving me the chance to write this diploma thesis, and to Christoph Bommer who kindly supported the thesis with the ressources and data of Siemens. Many thanks also to Martin Pinzger for his advice and encouragement and for the valuable feedback for the draft of this document. Many thanks to my parents for proof reading and for their continuous support during my studies. In this thesis we present the design and implementation of a plugin for the Eclipse platform that provides facilities for visualizing the history of a software project. The plugin integrates a frontend for a Release History Database (RHDB) into the Eclipse IDE and provides interfaces for data importers and extension points for visualization modules. The plugin includes a tree map module suitable for visualizing hierarchical data such as the metrics of files contained in
Evolution Impact of Code Clones – Identification of Structural and Change Smells based on Code Clones
No full textMany persons deserve thanks for their help in the realization of this thesis. I would first like to express my thanks to all persons who supported me during the last six months but remain unnamed in this acknowledgement. Special thanks goes to Professor Harald Gall for giving me the opportunity of writing this thesis. It was definitely a highlight during my studies at the University of Zürich. I would like to thank Beat Fluri for his support and input during the last six months. Thanks also go to Martin Pinzger for answering many questions. I would like to thank the CCFinder development team at the University of Osaka for providing this powerful tool for the use in this thesis. Special thanks also goes to my family: my father Werner Geiger for the interesting discussions and his interest in this thesis; my mother Marie-Theres Geiger for proofreading this work on a subject so different from her usual interests; my brother Gaudenz Geiger for his encouragement and his insistence that I relax sometimes. Code clones have long been recognized as bad smells in software systems and are assumed to caus
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
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
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
