SARL: OO Framework Specification for Static Analysis
No full textSemantic static analysis allows sound verification of program properties, that is, to prove that a given property holds for all possible executions. However, modern object-oriented applications make heavy use of third-party frameworks. These provide various functionalities (like libraries), as well as an extension of the execution model of the program. Applying standard models to statically analyze software relying on such frameworks could be potentially unsound and imprecise. In this paper we introduce SARL, a domain-specific language which allows one to specify the runtime behaviors of frameworks of object-oriented programs. Such specifications can be then applied to automatically generate annotations on program components of the application to model the framework runtime environment. In addition, SARL specifications document which aspects of a framework are supported by the static analyzer and how. We adopted SARL to model WindowsForms and ASP.NET, two of the most popular.NET frameworks in an existing industrial static analyzer (Julia). We then analyzed the three most popular GitHub repositories using these frameworks, comparing the results with and without SARL. Our experimental results show that the application of SARL sensibly improved the precision and soundness of the analysis without affecting its runtime performances
The Italian Version of the Robotics Learning Self-Efficacy Scale (RLSES-IT): Assessment of psychometric features in a sample of young students
Full text linkThis study evaluated the psychometric characteristics in the Italian context of the Robotics Learning Self-Efficacy Scale (RLSES). A sample of 353 young students attending an educational robotics (ER) course in their primary or secondary schools completed the assessment battery, including the RLSES and a validated questionnaire inquiring about students’ self-efficacy. Regarding the RLSES, an exploratory factor analysis and then a confirmatory factor analysis were applied on two random subsamples. The findings highlighted two reliable factors; the convergent and criterion-oriented validity were also established. This work demonstrates that the Italian RLSES can be considered a valid and reliable tool for evaluating students’ self-efficacy in robotics learning and supporting the teachers’ actions in ER teaching
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
Challenges of software verification
No full textSoftware verification aims to prove that a program satisfies some given properties for all its possible executions. Software evolved incredibly fast during the last century, exposing several challenges to this scientific discipline. The goal of the "Challenges of Software Verification Symposium" is to monitor the state-of-the-art in this field. This special issue of Software Tools for Technology Transfer presents novel theoretical directions and practical applications of these techniques. The papers in this special issue are extended versions of selected symposium papers from the proceedings of the 3rd Challenges of Software Verification Symposium (CSV), which took place at the Ca' Foscari University of Venice, Venice, Italy, June 6-7, 2024
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
