    Le service national de dépôt partagé Scholaris: Retours d’expérience de 3 universités québécoises​
    (2025-11-06) St-Cyr, Sophie; Behforouz, Nima; Charest, Laurence; Fontaine, Isabelle
    Le libre accès s’impose comme un modèle incontournable dans le paysage de la communication savante. Les dépôts institutionnels jouent un rôle crucial pour assurer la diffusion et la pérennité des travaux de recherche. Cependant, l’implantation et la gestion d’un dépôt institutionnel peuvent représenter un défi de taille. C’est dans cette optique que Scholaris, un service de dépôt partagé canadien fonctionnant avec le logiciel libre DSpace, a été développé. Développé par l’Association des bibliothèques de recherche du Canada (ABRC), le Conseil des bibliothèques universitaires de l’Ontario (OCUL) et les bibliothèques de l’Université de Toronto, en partenariat avec Scholars Portal et des experts, Scholaris offre un hébergement centralisé, des mises à jour coordonnées et une localisation sécurisée des données au Canada. Cette communication présentera les retours d’expérience de trois universités québécoises – l’Université de Montréal (grande institution), l’Université de Sherbrooke (taille moyenne) et l’Université Bishop’s (plus petite) – en tant qu’utilisatrices précoces de Scholaris. Ces établissements illustrent comment une technologie partagée peut s’adapter à des contextes variés tout en optimisant la gestion des dépôts.

    Everyday Diplomats: The Global Solidarity Movement for Timor-Leste, 1975-99
    (TiSA (Timor International Solidarity Archive), 2025) Loney, Hannah; Pereira, Zelia; Webster, David; Feijó, Rui Graça
    Solidarity activists with Timor-Leste (East Timor) during the period of Indonesian military occupation (1975-99) were involved in a form of diplomacy. It was messy and often loud; an unconventional approach compared to state diplomacy. Yet the movement emerged as an effective tool for the Timor-Leste cause, and as a constructive form of “other diplomacy” that often proved influential in shaping both government and Timorese actions. It legacy lingers even after Timor-Leste’s independence.

    Anthropocene Critical Radical Ecopedagogy (CREP) using Cellphilms
    (Bishop's University, 2023-04-01) Chbib, Bachar; Gulliver, Trevor
    The aim of my Master’s thesis is to inquire into the literature and recent theoretical research exploring the specific workings of belonging and identity formation of learners engaged with technology through the use of multimodal mobile devices such as smartphones or tablets to produce short films called cellphilms. I then look for the ‘lines of flight’ as proposed by Gilles Deleuze and Felix Guattari that may generate new ideas from the recent use of cellphilms in contemporary Participatory Action Research (PAR) in healthcare, social work and education. I then propose an auto-ethnographic use of cellphilming and an active engagement with play to learn performance and storytelling in outdoor nature class. I introduce a Critical Radical Ecopedagogy (CREP) to inform a PreK-9 curriculum for learning to belong in kinship with humans and non-humans. I suggest that affect induced, technologically enhanced ecopedagogy engaged with the practice of cellphilming, during ecology classes, can support enriched ethical and moral development towards community living and belonging in this troubled age of the Anthropocene.

    An Empirical Evaluation of Model Design and Code Representation for Deep Learning-Based Source Code Vulnerability Detection
    (Bishop's University, 2025-09-12) Khan, Abdullah; Malik, Yasir
    As modern software systems continue to grow in scale and complexity, ensuring their security has become an increasingly demanding challenge, with hidden vulnerabilities threatening both reliability and safety. Deep learning offers powerful approaches to automating vulnerability detection by capturing structural and semantic code patterns that are often missed by traditional rule-based techniques. Research in this area has largely advanced along two main paradigms: sequence-based, which treat code as token streams, and graph-based, which leverage structural representations of code. The rise of pre-trained transformers has further accelerated progress by modeling semantic and contextual nuances with greater fidelity. Yet key questions remain unresolved, including the specific contribution of pre-training to vulnerability detection, the relative merits of sequence-based and graph-based approaches, the influence of structural design choices within graph models, and the ability of these methods to generalize across different programming languages. This work undertakes a comprehensive empirical study to address these gaps. The results demonstrate that pre-training substantially improves detection performance, underscoring the value of contextualized embeddings for capturing code semantics. Graph-based architectures, particularly those built on code property graphs, consistently deliver more accurate results by integrating syntactic structures with semantic dependencies. The findings further reveal that fusing syntactic and semantic representations produces the most reliable detection of complex, real-world vulnerabilities. At the same time, current methods exhibit significant performance degradation when applied in multilingual settings, highlighting the urgent need for language-independent strategies. By examining the interplay of pre-training, model architecture, and code representation, this study establishes a rigorous evaluation framework that clarifies their individual and collective contributions to reliable vulnerability detection. Beyond advancing accuracy, it emphasizes the importance of explainability in helping developers understand detected risks, laying the groundwork for scalable, generalizable systems capable of securing today’s increasingly diverse and heterogeneous software environments.

    Heroes Arena: A Low-Latency Architecture for Fully On-Chain Card Battle Games
    (Bishop's University, 2025-09-12) Hu, Haoqing; Butler, Russell
    Fully on-chain games often suffer from significant interaction delays due to blockchain transaction latencies, hindering the user experience, especially in real-time gaming scenarios. This thesis presents Heroes Arena, a fully decentralized real-time card battle game deployed on the Ethereum Sepolia testnet, designed to minimize user-perceived latency. By employing a parallel architecture that loads all necessary blockchain data upon user login and subsequently executes all gameplay logic locally, this system offers immediate in-game feedback without additional blockchain confirmations. Game events and rewards, such as NFT distribution and in-game resources, are asynchronously queued and committed to the blockchain in order, ensuring consistency without interrupting player interaction. The complete game implementation—including real-time battles, NFT card management, resource purchasing, and timed reward mechanisms—was independently developed using Unity and Solidity smart contracts. Comparative analysis demonstrates that the proposed architecture achieves significantly improved responsiveness and simplicity compared to existing zero-knowledge proof-based methods and ephemeral rollup solutions.
