Hedy: An Inclusive, Multi-Lingual, and Gradual Programming Language (Invited Talk)
No full textSoftware is playing an increasing role in everyone’s lives, and therefore it is important (and fun!) for kids to become creators in the digital world. However, existing programming languages are not necessarily designed for learnability, with cryptic error messages and a lack of easily accessible resources. In this talk, Felienne will outline what issues existing tools have, and how these issues disproportionally affect underrepresented minorities in programming including girls, kids with disabilities and non-English learners. She will then outline her story of inventing and creating Hedy, an inclusive, multi-lingual and gradual programming language for learners. Hedy is open source, runs in the browser, is free to use, and is available in 54 different languages (Including English, Spanish, Chinese, Arabic and Hindi). Hedy was launched in early 2020 and now serves about 500,000 monthly users
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

BumbleBee: A Refactoring Environment for Spreadsheet Formulas
No full text<p>Spreadsheets are widely used in industry. It is estimated that end-user programmers outnumber regular programmers by a factor of 5. However, spreadsheets are error-prone: several reports exist of companies that have lost big sums of money due to spreadsheet errors. In previous work, spreadsheet smells have proven to be the cause of some of these errors.</p>
<p>To that end, we have developed a tool that can apply refactorings to spreadsheet formulas, implementing our previous work on spreadsheet refactoring, which showed that spreadsheet formula smells are very common and that refactorings for them are widely applicable and that refactoring them with a tool is both quicker and less error-prone.</p>
<p>Our new tool Bumblebee is able to execute refactorings originating from both these papers, by means of an extensible syntax, and can furthermore apply refactorings on entire groups of formulas, thus improving upon the existing tool RefBook. Finally, BumbleBee can also execute transformations other than refactorings.</p>
