Análisis y comparación de las propuestas recientes para diseñar casos de prueba desde los casos de uso orientados a verificar los aspectos funcionales del software
Get PDFEste documento contiene la relación del trabajo de investigación de la tesis para optar al título de maestría en ingeniería de software, respecto de un análisis y comparación de las propuestas recientes para el diseño de casos de prueba desde los casos de uso orientados a verificar los aspectos funcionales del software. En el transcurso de la investigación consultamos la literatura hasta encontrar las propuestas promulgadas de 2000 en adelante alrededor de esta temática. Las propuestas seleccionadas se aplicaron a un estudio de caso con el objetivo de analizar y evaluar los resultados a través de métricas valorativas. Posteriormente, se identificaron los conceptos que las soportan y finalmente se estructuró una nueva propuesta, con el objetivo de recoger las mejores prácticas que exponen y con base en estos conceptos. También se presenta una descripción de cada una de las propuestas y al final una identificación de los conceptos que las soportan. Este trabajo parte de una necesidad en la industria y la academia relacionada con las pruebas del software. La industria requiere propuestas que describan metodologías para aplicar pruebas desde las fases iniciales del ciclo de vida del software, y la academia necesita textos que describan métodos útiles o de fácil incorporación a los procesos formativos. Por lo que esta tesis es una fuente de consulta para la industria, dado su carácter empírico, y para la academia, dado su contenido teórico-aplicativo. La consulta del estado del arte permitió identificar nueve propuestas que describen métodos para diseñar casos de prueba desde los casos de uso para verificar los aspectos funcionales del software. Cada una de ellas detalla una serie de pasos para lograr el objetivo planteado, y aunque al aplicarlos sobre el estudio de caso se encontraron dificultades también se identificaron buenas prácticas. El resultado del proceso se estructuró en tablas comparativas, las cuales constituyeron la fuente para identificar los conceptos y procesos clave de las propuestas que luego se estructuraron en un método que recoge las mejores prácticas. Al final de este documento se plantean cuestiones y temas para desarrollar trabajos futuros alrededor de esta temática que no se cubren en el desarrollo de la tesis dado que están por fuera de su alcance. Entre estos temas cabe mencionar: pruebas estructurales o de caja blanca, automatización de las pruebas, validación del software, requisitos no funcionales, entre otros. Este trabajo hace dos aportes fundamentales: 1) el análisis comparativo, que es novedoso dado que en la revisión a la literatura no se encontraron estudios similares; y 2) la integración, estructuración, descripción y aplicación de una nueva propuesta para diseñar casos de prueba desde los casos uso, en la que se utiliza las buenas prácticas de las propuestas analizadas, y se aportan conceptos novedosos y actuales en el campo de la ingeniería del software./Abstract. This document contains the list of the research of the thesis for the degree of expertise in software engineering, for analysis and comparison of recent proposals for the design of test cases from use cases designed to verify aspects functional software. During the research we consulted the literature to find the proposals enacted from 2000 onwards around this theme. The selected proposals were applied to a case study in order to analyze and evaluate the results through valuation metrics. Subsequently, we identified the concepts that support and finally a new proposal was structured with the aim to collect best practices that expose and based on these concepts. It also presents a description of each of the proposals and finally identification of the concepts that support them. This paper is a need in industry and academia related to software testing. The industry requires proposals that describe methodologies for applying evidence from the initial phases of software life cycle, and academia need texts that describe methods useful or easily incorporated into the training processes. So this thesis is a resource for the industry, given its empirical character, and academia, because they contain theory and application. The state of the art consultation identified nine proposals that describe methods for designing test cases from use cases to verify the functional aspects of software. Each details a series of steps to achieve the stated objective, and even when applied to the case study found difficulties were also identified best practices. The above process was structured in comparative tables, which were the source to identify key concepts and processes of the proposals which are then structured in a method that incorporates the best practices. At the end of this paper raises questions and issues to develop future work around this issue not covered in the development of the thesis as they are outside its scope. These issues include: evidence of structural or white box test automation, software validation, non-functional requirements, among others. This paper makes two fundamental contributions: 1) the comparative analysis is novel because in the literature review found no similar studies, and 2) integration, structuring, describing and implementing a new proposal to design test cases from use cases, which is used best practices of the proposals analyzed, and are provided for current and new concepts in the field of software engineering.Maestrí

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
