Test Management Automation: Lessons Learned from a Process Improvement Experiment
No full textTest management aims at organizing, documenting and executing test cases, and at generating execution reports. The adoption of a support tool and of a standard process for such activities is expected to improve the current practice. ITALO is an European project devoted to the evaluation of the benefits coming from test management automation. In this paper the experiences collected and the lessons learned during ITALO are summarized. A formal methodology was adopted for the selection of a support tool among those available from the market. A survey of the current practice in component testing was conducted to adapt the existing process model so as to obtain the greatest benefits from automation. An experiment was then designed to measure the effects that are expected to be produced by the new test process complemented with the introduction of the support tool.
Pilot projects were conducted to measure the benefits obtained from tool usage and process modification. Results are presented in this paper, together with a discussion that allows their interpretatio
Effective Feature Analysis for Tool Selection
No full textThe ESSI PIE ITALO project aims at improving the component test phase for object oriented software. The main steps of the project include the selection of a support tool and the set up of an experiment to quantify the effects of its adoption. Tool selection was performed according to DESMET guidelines for feature analysis. Since the choice of a good support is crucial for the success of the whole project, but the resources for the selection process vere limited, the feature analysis was performed so as to be extremely effective, i.e. able to give the maximum discrimination at the minimum cost.
During each step of the feature analysis (feature elicitation, tool assessment and score analysis) several Effective Feature Analysis Strategies (EFAS) were adopted with the purpose of increasing the discrimination between tools and reducing the cost needed to converge the final choice. This paper reports on that experience and highlights all the lessons learned on terms of acquired EFA
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
