Since September 2023, the reform of initial teacher training (RFIE) has been profoundly transforming the teaching profession. This year, it is taking a new step forward with the replacement of the former teaching-oriented master's degrees and the agrégation by master's degrees in teaching sections 4 and 5. Led by the Faculty of Education and Training Sciences (FaSEF), in collaboration with the Faculties of Science and EMCP (Economics, Management, Communication, and Political Science), the reform is accompanied by a strengthened partnership with HENALLUX (Namur-Liège-Luxembourg University College).

The University of Namur takes another step forward in its commitment to supporting digital transformation. It is joining the prestigious European Research Center for Information Systems (ERCIS) network as a Partner Institution, via the MINDIT research center (Management de l'Information et Transformation Numérique).

Conceptual field theory and didactic situation theory Two complementary theories for thinking about and organizing mathematical learningIn the first part of this talk, I'll propose an introductory situation in literal arithmetic (Barallobres & Giroux, 2008) that will enable me to introduce and illustrate the main concepts and methodological tools of the theory of didactic situations developed by Guy Brousseau (Brousseau, 1997; Bessot, 2024). In the second part, I will give a brief presentation of Gérard Vergnaud's theory of conceptual fields (Vergnaud, 1990; Durand-Guerrier and Saby, 2023), then show how this theory helps to shed further light on the introductory situation.The contributions of the anthropological theory of didactics The Anthropological Theory of Didactics (TAD, Chevallard, 2001) aims to explain why and how a given knowledge lives in a certain institution, and/or is transformed as it passes from one institution to another. This perspective and some of its evolutions will be presented and illustrated in this talk.Students' activities and teachers' practices in the mathematics classroom: analysis methodology with Activity TheoryIn this talk, we will present the founding assumptions of the Activity Theory framework adapted to the Didactics of Mathematics (TADM, Vandebrouck, 2008), showing how this theory gives importance to fine-grained analyses of mathematical knowledge to appreciate classroom developments. We will then exemplify some of these aspects on the teaching of limits at university (Bridoux and Grenier-Boley, 2024).BibliographyBarallobres, G., & Giroux, J. (2008).

In recent years, public debate has been regularly disrupted by various attempts to distort "information." While this phenomenon is as old as information itself, digital technology, the powerful interactivity offered by online platforms, and recent developments in generative artificial intelligence have given it a whole new dimension. Manipulated online information spreads virally, reaching internet users around the world in a matter of minutes. It poses serious risks to society and threatens democracy and the rule of law. To see this, one need only recall events such as the US and French presidential elections, the Covid-19 pandemic, the war in Ukraine, the terrorist attack at the Nova festival in 2023, and the war in Gaza.  Faced with this phenomenon, actors from all sectors have been mobilizing for several years. This conference offers a legal perspective on the manipulation of online information in relation to freedom of expression and the right to information from the point of view of European law. It focuses, on the one hand, on the response of the European Union legislator to combat online disinformation and, on the other hand, on mechanisms for protecting "quality" information.Free admission.

Terminator to talk about AI? Wall-E to talk about technological dependence? The Truman Show to discuss social media? In a new book, two professors from UNamur, Anthony Simonofski (digital transformation—EMCP Faculty—NaDI Institute) and Benoît Vanderose (software engineering—Faculty of Computer Science—NaDI Institute), take readers on a journey at the crossroads of digital technology and cinematic imagination. 

Synopsis The spreading of internet-based technologies since the mid-90s has led to a paradigm shift from monolithic centralized information systems to distributed information systems based upon the composition of software components, interacting with each other and of heterogeneous natures. The popularity of these systems is nowadays such that our everyday life is touched by them.Classically concurrent and distributed systems are coded by using the message passing paradigm-according to which components exchange information by sending and receiving messages. In the aim of clearly separating computational and interactional aspects of computations, Gelernter and Carriero have proposed an alternative framework in which components interact through the availability of information placed on a shared space. Their framework has been concretized in a language called Linda. A series of languages, referred to nowadays as coordination languages, have been developed afterwards. In addition to providing a more declarative framework, such languages nicely fit applications like Facebook, LinkedIn and Twitter, in which users share information by adding it or consulting it in a common place. Such systems are in fact particular cases of so-called socio-technical systems in which humans interact with machines and their environments through complex dependencies. As coordination languages nicely meet social networks, the question naturally arises whether they can also nicely code socio-technical systems. However, answering this question first requires to see how well programs written in coordination languages can reflect what they are assumed to model.This thesis aims at addressing these two questions. To that end, we shall use the Bach coordination language developed at the University of Namur as a representative of Linda-like languages. We shall extend it in a language named Multi-Bach to be able to code and reason on socio-technical systems. We will also introduce a workbench Anemone to support the modelling of such systems. Finally, we will evidence the interest of our approach through the coding of several social-technical systems.

The university has a duty to set an example in terms of sustainable development, in all three of its dimensions: economic, social and environmental. Sustainable "in form" through the way it manages its infrastructures and assets, and sustainable "in substance" through its commitment to research and teaching activities, in order to actively contribute to the environmental transition. All in line with the United Nations' Sustainable Development Goals (SDGs).

SynopsisA honeypot is a security tool deliberately designed to be vulnerable, thereby enticing attackers to probe, exploit, and compromise it. Since their introduction in the early 1990s, honeypots have remained among the most widely used tools for capturing cyberattacks, complementing traditional defenses such as firewalls and intrusion detection systems. They serve both as early warning systems and as sources of valuable attack data, enabling security professionals to study the techniques and behaviors of threat actors.While conventional honeypots have achieved significant success, they remain deterministic in their responses to attacks. This is where adaptive or intelligent honeypots come into play. An adaptive honeypot leverages Machine Learning techniques, such as Reinforcement Learning, to interact with attackers. These systems learn to take actions that can disrupt the normal execution flow of an attack, potentially forcing attackers to alter their techniques. As a result, attackers must find alternative routes or tools to achieve their objectives, ultimately leading to the collection of more attack data.Despite their advantages, traditional honeypots face two main challenges. First, emulation-based honeypots (also known as low- and medium-interaction honeypots) are increasingly susceptible to detection, which undermines their effectiveness in collecting meaningful attack data. Second, real-system-based honeypots (also known as high-interaction honeypots) pose security risks to the hosting organization if not properly isolated and protected. Since adaptive honeypots rely on the same underlying systems, they also inherit these challenges.This thesis investigates whether it is possible to design a honeypot system that mitigates these challenges while still fulfilling its primary objective of collecting attack data. To this end, it proposes a new abstract model for adaptive self-guarded honeypots, designed to balance attack data collection, detection evasion, and security preservation, ensuring that it does not pose a risk to the rest of the network.Jury membersProf. Wim VANHOOF, President, University of NamurProf. Jean-Noël COLIN, Promoter, University of NamurProf. Florentin ROCHET, Internal Member, University of NamurProf. Benoît FRENAY, Internal Member, University of NamurProf. Ramin SADRE, External Member, Catholic University of LeuvenDr. Jérôme FRANCOIS, External Member, University of LuxembourgYou are cordially invited to a drink, which will follow the public defense.
