Federated Neuromorphic Intelligence: Advancing Robustness, Efficiency, And Continual Adaptation In Edge Environments, Manh V. Nguyen

Dissertations

This dissertation investigates how spiking neural networks (SNNs) can improve federated edge intelligence by advancing three interconnected goals: communication efficiency, adversarial robustness, and continual adaptation. As edge computing deployments expand across Internet of Things (IoT), sensing, and privacy-sensitive applications, conventional federated learning approaches built around artificial neural networks (ANNs) face growing limitations in power consumption, bandwidth demand, and resilience to real-world uncertainty. SNNs offer an alternative computational paradigm based on event-driven, sparse, and temporally structured processing that is naturally suited to constrained edge environments. However, their behavior in practical federated settings remains insufficiently understood.

To address this gap, this dissertation …

Our Stories: Black Parents’ Experiences At K-12 Predominantly White Institutions, Jason Thompson

Dissertations

Black parents of Black children attending K–12 predominantly White institutions (PWIs) often experience stress as they navigate school environments where they may be perceived as uninterested, combative, or “token” members of the school community. These deficit-based perceptions can cause Black parents to limit school interactions, question whether their perspectives will be valued, and develop distrust toward school personnel. Although research has examined Black students’ experiences in PWIs, fewer qualitative studies have centered on Black parents’ stories. Capturing these experiences in parents’ own words helps challenge harmful stereotypes and offers schools, especially school counselors, deeper insight into strengthening relationships with Black …

Cripping The Border – Acompañamiento As Access: An Ethnographic Case Study Of Transborder Youth With Disabilities, Marco O. Amaral

Dissertations

The U.S.-Mexico border is a historical, geopolitical site of intense militarization where colonial logics of "othering" converge to marginalize disabled transborder youth. While transborder studies have expanded, students with disabilities remain relegated to the "void" and contained by educational systems that prioritize surveillance over access. Grounded in Sepúlveda’s (2011) acompañamiento and Transborder DisCrit, this ethnographic case study examines the lived experiences of both students and their families who cross the border daily to attend school in the U.S. It frames these journeys not as mere commutes, but as acts of defiance within the broader disability rights movement.

Organizing To Engage: A Framework For Conflict Strategy, Paul Mason Carpenter

Dissertations

Conflict strategy can be exceedingly complex. While many of the basics are simple, even the simple can be highly complicated to execute. The Schlieffen Plan in World War I appeared straight forward, but execution was a great deal more complex. It failed and the result was years of trench warfare.  In addition, leaders entering conflict may not fully appreciate the full context, its effect, and the need for a long term result--a better state of peace.

Strategy and tactics may be challenging to transform as an engagement evolves. In addition, strategists must often commit to courses of action within very …
