Season 1, Episode 5: Translating Franz Kafka’s “The Metamorphosis”: A Conversation with Dr. Mark Harman
No full textIn this episode, Dr. Mark Harman, Professor Emeritus of German and English at Elizabethtown College and award-winning translator of Kafka and other authors, discusses his recent work, translating Kafka’s novella, commonly titled, “The Metamorphosis” in English but which Mark entitles, “The Transformation.” His translation is part of a forthcoming collection of Kafka stories on which Mark is currently working. We discuss the story, the translation process, and Kafka’s enduring appeal
An overview of program slicing
No full textMARK HARMAN and ROBERT HIERONS review three semantic paradigms for slicing — static, dynamic and conditioned; and two syntactic paradigms — syntax-preserving and amorphous. Slicing has been applied to many software development problems including testing, reuse, maintenance and evolution. This paper describes the main forms of program slice and some of the applications to which slicing has been put
Genetic programming for reverse engineering
No full texta particular emphasis on the growing importance of recent developments in genetic programming and genetic improvement for reverse engineering. This includes work on SBSE for remodularisation, refactoring, regression testing, syntax-preserving slicing and dependence analysis, concept assignment and feature location, bug fixing, and code migration. We also explore the possibilities for new directions in research using GP and GI for partial evaluation, amorphous slicing, and product lines, with a particular focus on code transplantation. This paper accompanies the keynote given by Mark Harman at the 20 th Working Conference on Reverse Engineering (WCRE 2013). I
Crawlability Metrics for Web Applications
No full textAutomated web crawlers can be used to explore and exercise portions of a web application under test. However, the possibility to achieve full exploration of a web application through automated crawling is severely limited by the choice of the input values submitted with forms. Depending on the crawler's capabilities, a larger or smaller portion of web application will be automatically explored.
In this paper, we introduce web crawlability metrics to quantify properties of application pages and forms that affect crawlability. Moreover, we show that our metrics can be used to identify the boundaries between those parts of the application that can be successfully crawled automatically and those parts that will require manual intervention or other crawlability support. We have validated our crawlability metrics on real web applications, for which low crawlability was indeed associated with the existence of pages never exercised during automated crawling
Improving Web Application Testing Using Testability Measures
No full textOne of the challenges of testing web applications derivesfrom their dynamic content and structure. As we testa website, we may discover more about its structure andbehaviour. This paper proposes a framework for collectionof testability measures during the automated testing process(termed ‘in-testing’ measure collection). The measuresgathered in this way can take account of dynamic and contentdriven aspects of web applications, such as form structure,client-side scripting and server-side code. Their goalis to capture measurements related to on-going testing activity, indicating where additional testing can best lead to higher overall coverage. They denote a form of ‘web testability’ measures. The paper reports on the implementation of a prototype Web Application Testing Tool, WATT, illustrating the in- testing measure collection approach on 34forms taken from 14 real world web applications
Clustering Test Cases to Achieve Effective and Scalable Prioritisation Incorporating Expert Knowledge
No full textPair-wise comparison has been successfully utilised in order to prioritise test cases by exploiting the rich, valuable and unique knowledge of the tester. However, the prohibitively large cost of the pairwise comparison method prevents it from being applied to large test suites. In this paper, we introduce a cluster-based test case prioritisation technique. By clustering test cases, based on their dynamic runtime behaviour, we can reduce the required number of pair-wise comparisons significantly. The approach is evaluated on seven test suites ranging in size from 154 to 1,061 test cases. We present an empirical study that shows that the resulting prioritisation is more eective than existing coverage-based prioritisation techniques in terms of rate of fault detection. Perhaps surprisingly, the paper also demonstrates that clustering (even without human input) can outperform unclustered coverage-based technologies, and discusses an automated process that can be used to determine whether the application of the proposed approach would yield improvement
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
