One of these changes reflects a revisitation of andragogic approaches, as increasing numbers of adult learners enrol in e- courses, mainly for convenience reasons – they allow for information dissemination in a manner which satisfies their concrete professional needs, at a pace and in a time frame that can be easily fitted into their busy schedules. Relying on the andragogic principles developed by Malcolm Knowles, this paper sets to analyse them in the framework of foreign language learning, as the study of foreign languages might be one of the most challenging instruction areas for adult learners. Thus, the article first reviews some of the most frequently used methodologies of language teaching such as the communicative approach, grammar-translation, task-based learning, the natural approach or suggestopoedia. The aim of this appraisal is to detect which of them are most suited for adult students on the one hand and for virtual classrooms, on the other. Special emphasis is placed on the transformative learning theory advanced by Jack Mezirow, which is usually applied in adult education. Keywords: language teaching, e-learning, adult learner, transformative learning 1. Introduction The digital age has led to a reorganisation of the complex structures of social, professional and economic layers. It has represented a genuine game-changer in education as well, that has entailed an adjustment of the instructional paradigm in respect of all the elements involved, from learner profiles to curriculum design and reconsideration of teaching methods. This paper draws on an interdisciplinary approach, as it tackles issues pertaining to foreign language teaching, e-learning and principles of andragogy. It focuses on three aspects of the broad educational framework: learner – in this particular case, the adult learner –, subject matter – foreign language acquisition –, and medium – online learning as opposed to traditional forms of instruction. The above-mentioned training triad can be addressed from various perspectives; however, in this particular instance, the focus 1 Corresponding author, lecturer PhD, Romanian-American University, Bucharest, [email protected] 7 JOURNAL OF INFORMATION SYSTEMS & OPERATIONS MANAGEMENT, Vol. 14.1, May 2020 will be on the learners, on their needs and expectations as to the result of their learning endeavours. In the broader context of adult education, language learning is probably in the top three of all types of courses (together with computer literacy and management skills) in which adult persons enrol once they graduate some level of formal education. Most learners take up language classes as a result of a need that arises in their social and professional lives: “Some may need mainly speaking and listening skills, other may have to learn to read and write for particular purposes. Others may need informal language mainly for social interaction rather than the more formal language required for work purposes. Alternatively, they may be more interested in cultural aspects of language learning rather than the strictly functional ones” [1]. In the last decades, the advancement of the Internet and the continuous progress of information technologies have made it possible for people to engage in online learning as well, which is oftentimes preferred to traditional

    Source Code Stylometry and Authorship Attribution for Open Source by Daniel Watson A thesis presented to the University of Waterloo in fulfillment of the thesis requirement for the degree of Master of Mathematics in Computer Science Waterloo, Ontario, Canada, 2019 c Daniel Watson 2019 Author's Declaration I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. ii Abstract Public software repositories such as GitHub make transparent the development history of an open source software system. Source code commits, discussions about new features and bugs, and code reviews are stored and carefully attributed to the appropriate developers. However, sometimes governments may seek to analyze these repositories, to identify citi- zens who contribute to projects they disapprove of, such as those involving cryptography or social media. While developers who seek anonymity may contribute under assumed identi- ties, their body of public work may be characteristic enough to betray who they really are. The ability to contribute anonymously to public bodies of knowledge is extremely impor- tant to the future of technological and intellectual freedoms. Just as in security hacking, the only way to protect vulnerable individuals is by demonstrating the means and strength of available attacks so that those concerned may know of the need and develop the means to protect themselves. In this work, we present a method to de-anonymize source code contributors based on the authors' intrinsic programming style.

It is with many hours. In order to encourage students to put in these hours, these ideas in mind that we conceived Code Hunt, a game for we built Code Hunt, a game that enables players to program coding against the computer by solving a sequence of puzzles against the computer with clues provided as unit tests. The game of increasing complexity. Code Hunt is unique among coding has become very popular and we are now running worldwide systems and among games in that it combines the elements of contests where students have a fixed amount of time to solve a set of puzzles. This paper describes Code Hunt and the contest both to produce just what we need to get students to put in those experience it offers. We then show some early results that hours of practice to hone their programming skills. Along the demonstrate how Code Hunt can accurately discriminate between way, they also learn to understand testing, since the game is good and bad coders.

    On the Feasibility of Malware Authorship Attribution Saed Alrabaee, Paria Shirani, Mourad Debbabi, and Lingyu Wang Concordia University, Montreal, Canada Abstract. There are many occasions in which the security community is interested to discover the authorship of malware binaries, either for digital forensics analysis of malware corpora or for thwarting live threats of malware invasion. Such a discovery of authorship might be possible due to stylistic features inherent to software codes written by human programmers. Existing studies of authorship attribution of general pur- pose software mainly focus on source code, which is typically based on the style of programs and environment. However, those features critically depend on the availability of the program source code, which is usually not the case when dealing with malware binaries. Such program binaries often do not retain many semantic or stylistic features due to the compila- tion process. Therefore, authorship attribution in the domain of malware binaries based on features and styles that will survive the compilation process is challenging. This paper provides the state of the art in this literature. Further, we analyze the features involved in those techniques. By using a case study, we identify features that can survive the compi- lation process. Finally, we analyze existing works on binary authorship attribution and study their applicability to real malware binaries. 1 Introduction Authorship attribution comprises an important aspect of many forensic investi- gations, which is equally true in the computer world. When a malware attacks computer systems and leaves behind a malware corpus, an important question to ask is 'Who wrote this malware?'.

Ecosystem research has thus far focused on understanding the structure and dynamics of already existing ecosystems. However much less attention has been devoted to the emergence of ecosystems. I first theoretically develop an institutional approach to ecosystems, arguing that the ecosystem is an organisational field which has value co-creation as its recognised area of institutional life. Synthesising the theories of dominant design, social movements, and institutional entrepreneurship, I identify four activities that drive the processes of ecosystem emergence: resource, technological, institutional and contextual activities.
