Cotheorizing Healing With Undergraduate Queer And Trans Latina Survivors Of Power-Based Violence, Kimberly Correa

Dissertations

Current research on healing from power-based violence highlights the importance of integrating victim-survivors’ personal culture and identities into healing approaches, yet few studies actually focus on the culturally distinct healing processes of victim-survivors (O’Brien & Macy, 2016; Sinko et al., 2023). Grounded in Jotería theory (Alvarez, 2023) and Latina/Chicana feminist frameworks (Garcia, 1989), this qualitative study employs queer pláticas as both a methodology and method to center culturally rooted dialogue, reciprocity, and cariño as a political praxis. This study explores how six queer and trans Latina undergraduate victim-survivors conceptualize healing from power-based violence and how their identities, cultural values, and …

The TRA is an algebraic method for solving linear ordinary differential equations of the second order. The advantage of the method in being algebraic is reinforced by the analytic power of orthogonal polynomials and special functions. On the computational side, it is favored as being reliant on powerful numerical techniques that deal with tridiagonal matrices such as Gauss quadrature and continued fraction. In the method, the solution of the differential …

Fully Decentralized Hierarchical Federated Learning At The Edge With Post-Quantum Secure Communication, Tariq Qayyum

Dissertations

Federated learning (FL) enables collaborative model training without centralizing raw data, but deploying FL at scale in real edge environments remains challenging because iterative training and aggregation must operate over heterogeneous, resource-constrained, and often mobile devices with time-varying connectivity. Conventional hierarchical federated learning (HFL) partially mitigates communication cost by introducing fog/edge aggregation, yet many designs retain cloud-based global aggregation and cloud-centric coordination. This places wide-area network latency on the critical path of every training round, creates a single point of failure, and limits responsiveness as model sizes and federation scale grow. Moreover, moving coordination and aggregation closer to the edge …

Feedback In Digital Game-Based Learning: A Taxonomy And The Design And Empirical Evaluation Of A Feedback System In A Mathematics Serious Game, André Almo

Dissertations

Digital Game-Based Learning (DGBL) is an active, student-centred pedagogical approach in which feedback plays a central role by informing learners’ actions, guiding decision-making and shaping motivation and engagement. Despite its importance, feedback in serious games is often described inconsistently and insufficiently in research, limiting comparability across studies and the accumulation of design knowledge, particularly for children. This thesis addresses these gaps through two complementary contributions: the development of a taxonomy for feedback design in digital serious games and the empirical evaluation of a taxonomy-informed feedback system in a mathematics game for primary school students. First, this work introduces the Taxonomy …
