Priorização de anomalias arquiteturais versus refatoração de artefatos de código: um estudo envolvendo sistemas de software em evolução
Get PDFSoftware architectural projects tend to evolve prioritizing the reuse of their components in
order to avoid code refactoring. However, this reuse does not always happen as expected,
mainly due to structural problems of the projects, lack of planning and constant refactorings.
In general, structural problems are related to the existence of architectural anomalies
and to the increasing scope of its components. The scope of an architectural component
refers to the percentage of dependence that it has in relation to the other components
of the system. Unfortunately, there is a lack of studies that address the prioritization of
architectural anomalies as a way to minimize unwanted code refactoring operations. It
is known that anomalies treatment order impacts directly on the number of refactoring
operations. In this context, there is a growing demand for strategies capable of prioritizing
the treatment of architectural anomalies in order to minimize the number of refactoring
operations. This master’s research work analyzed three evolving software systems, with
the objective of providing support for the prioritization of the handling of anomalies in
order to interfere in the refactoring of code elements of evolving software systems. In
this context, the contributions emerge: (i) Definition of mechanisms capable of relating
the occurrence of architectural anomalies with the number of refactoring operations that
occur in the code, (ii) development of a computational solution, and (iii) empirical results.
We understand that the mechanisms for relation of architectural anomalies with code
refactoring operations in (i) and the development of a computational solution in (ii), will
be useful to support developers and architects in the decision making about prioritization
in the treatment of anomalies architecture. For the three applications evaluated, the scope
proved to be a strong indicator for prioritization in the treatment of anomalies for less
refactored architectural projects. When properly prioritizing the treatment of architectural
anomalies, it is expected to contribute to the construction of architectural projects with
fewer structural problemsProjetos arquiteturais de software tendem a evoluir priorizando o reuso de seus componentes,
de modo a promover a evolução dos artefatos de código livre de refatorações não
esperadas. No entanto, este reuso nem sempre acontece como esperado, devido principalmente
a problemas estruturais dos projetos, oriundos de falta de planejamento e constantes
refatorações. Problemas estruturais, em sua maioria, estão relacionados à existência de
anomalias arquiteturais e ao escopo crescente de seus componentes. O escopo de um componente
arquitetural refere-se ao percentual de dependência que ele possui em relação aos
demais componentes do sistema. Infelizmente, existe uma carência de estudos que abordam
a priorização de anomalias arquiteturais como forma de minimizar operações indesejadas
de refatoração de código. Sabe-se que a ordem de tratamento das anomalias interfere
diretamente no número de operações de refatoração. Neste contexto, há uma demanda
crescente por estratégias capazes de priorizar o tratamento de anomalias arquiteturais de
modo a minimizar o número de operações de refatoração. Este trabalho de pesquisa de
mestrado analisou três sistemas de software em evolução, com o objetivo de prover suporte
a priorização do tratamento de anomalias de modo a interferir na refatoração de elementos
de código de sistemas de software em evolução. Neste contexto, emergem as contribuições:
(i) Definição de mecanismos capazes de relacionar a ocorrência de anomalias arquiteturais
com o número de operações de refatoração que acontecem no código, (ii) Desenvolvimento
de uma solução computacional e (iii) resultados empíricos. Entendemos que os mecanismos
para relação das anomalias arquiteturais com as operações de refatoração no código em
(i) e o desenvolvimento de uma solução computacional em (ii), serão úteis para apoiar
desenvolvedores e arquitetos na tomada de decisão acerca da priorização no tratamento
de anomalias arquiteturais. Para as três aplicações avaliadas, o escopo mostrou ser um
forte indicador para priorização no tratamento de anomalias para projetos arquiteturais
menos refatorados. Ao priorizar adequadamente o tratamento de anomalias arquiteturais
espera-se contribuir para a construção de projetos arquiteturais com menos problemas

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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
