Spying The Lie: Insider Threat Prevention In National Security, Jazma M. Parker

Journal of Strategic Security

Insider threats pose significant risks to critical assets within the United States. The US intelligence community has already experienced the consequences of insider compromise, such as the unauthorized release of classified material to WikiLeaks and foreign adversaries. Traditional mitigation strategies have struggled to keep pace with the evolving threat landscape. This article recommends updated interventions to detect and prevent insider threats within the Department of Defense and the Intelligence Community. A review of current research and best practices reveals three targeted strategies. First, organizations must prioritize the detection and reporting of anomalous behaviors that often precede insider incidents. Achieving this …

Escalation By Algorithm, Restraint By Architecture: Pakistan’S Military Ai Divergence, Sajjad Ahmed, Ahmad Nizar Yaakub, Asma Javed

Journal of Strategic Security

Debates on military artificial intelligence (AI) remain skewed toward great power dynamics, oscillating between techno-optimist celebrations of speed and techno-pessimist warnings of collapse. This binary overlooks how middle powers, operating under nuclearized rivalry and asymmetric sanction risk, embed restraint into organizational and technical practice. This article develops Systems Restrained Realism (SRR), a framework that extends defensive realism into the machine age by theorizing restraint as a deliberate doctrinal posture rather than a symptom of incapacity. Using Pakistan as a critical case, the study draws on expert interviews, procurement manuals, and UN submissions to demonstrate how restraint is operationalized through latency …

Shadow Logistics: Military Vulnerability Through Civilian Dependence, Gilles A. Paché

Journal of Strategic Security

The rapid evolution of civilian-origin technologies repurposed for defense is reshaping the foundations of logistical advantage and altering the conditions under which armed forces operate. Modern missions rely on an extensive ecosystem of infrastructures—port terminals, cloud services, data platforms, and civilian contractors—whose reliability frequently lies beyond the authority of public institutions. This environment gives rise to shadow logistics, a network of civilian systems largely absent from conventional doctrine yet capable of producing significant operational disruptions when failures occur. Case studies show that some dark assets, whether physical or informational, can act as multipliers of effectiveness while simultaneously creating systemic vulnerabilities …

New Developments In Space-Filling Designs, Xiankui Yang

USF Tampa Graduate Theses and Dissertations

This dissertation presents three methodological advancements to improve the construction of space-filling designs for meeting different needs of computer experiments. Traditional space-filling designs focus on achieving uniform coverage in the input space, ensuring that design points are spread evenly throughout. However, in some scientific and engineering applications, varied density of design points may be desired for more efficient data collection when prior knowledge implies different emphases. In other cases, ensuring good coverage and/or spread of the response values allows better performance of fitted models in the next stage of applications. Many processes involve variation in response values. Therefore, incorporating variation …

Unquaint Pigs’ Stakeholder Perspectives On Wild Swine In Central Western Florida, Tyler Koerner

USF Tampa Graduate Theses and Dissertations

The Anthropocene presents important questions for how to address the continuous transferal of new species into new spaces and the cascading impacts of environmental transformations. Novel ecosystems present one such outline for conservation that acknowledges the modification of historic ecosystems and the social entanglements that arrive with new species. I argue that novel ecosystems can benefit from further anthropological integrations that aid in describing the entanglements of introduced species and the pursuit of best managerial outcomes. For wild swine in Florida, the adoption of a novel approach is especially relevant because of entanglements with historic and modern Floridian stakeholders and …

The Heterogeneous Response Of Astrocytes In Different Brain Regions Under Metabolic Stress, Pawan Kumar Thapaliya

USF Tampa Graduate Theses and Dissertations

Astrocytes play a central role in maintaining ionic homeostasis, neurotransmitter clearance, and brain en-ergy metabolism. Their excitability, reflected in activity-evoked intracellular sodium (Na+, [Na+]i) and calcium (Ca2+,[Ca+]i) dynamics, is increasingly recognized as a critical determinant of neuronal function and vulnerability, particularly under metabolic stress. Despite their importance, the mechanisms underlying astrocytic ionic signaling and its regional heterogeneity remain incompletely understood. In this thesis, I developed detailed computational and biophysical models to investigate astrocytic Na+ and Ca2+ dynamics, their bioenergetic consequences, and the roles of key ion transporters under physiological and metabolically stressed conditions, validating the models against experi- mental data. …

In response to increased cyberattacks against digital infrastructures, significant contributions have been made to the education of software-based cybersecurity principles through online resources, coursework, and other means. However, there is a lack of accessible platforms dedicated to the learning of hardware-based cybersecurity principles. Specifically, topics such as side-channel attacks or fault injection attacks can be challenging to study without expensive hardware resources. To address this need, we propose the Hardware Cluster for Key Security and Education Experiments (HaCKSEE) platform. HaCKSEE is an experiment-oriented platform designed to democratize hardware security education. The proposed platform allows students to conduct configurable hardware security …

Microarchitectural Vulnerabilities And Performance Tradeoffs In Shared Scientific Computing, Zyad Abd-Elrahman, Santosh Pandey

Bellini College REU Symposium (BCREUS)

Introduction & Problem Statement

Shared scientific computing platforms are built for speed and utilization, but they create a security problem that isolation alone can't fully solve. Even with TEEs, containers, or a privilege separation in place, the hardware underneath remains a shared resource. Speculative execution, cache contention, interconnect timing, and similar microarchitectural effects can leak information or create integrity risks across protection boundaries without any malicious code involved. For CI operators running graph workloads, HPC kernels, or ML pipelines in co-tenanted systems, the threat is inherent in normal execution. The real question isn't whether these vulnerabilities exist, but it's what …

Risa: Robotic Interface For Sit-To-Stand Assistance, Hieu Tran, Rinat Mynnakhmetov, Ricardo Frumento Sr, Yu Sun

Bellini College REU Symposium (BCREUS)

Mobility limitations in older adults are expected to become increasingly prevalent, along with the larger proportion of the world’s elderly population over the next decades [1]. Among these problems is the difficulty many elderly individuals face when transitioning from a seated to a standing pose. Loss of lower-body strength and balance makes this daily activity near impossible without assistance. To address this motor impairment, solutions were developed. For example, the Elderly Bodily Assistance Robot (E-BAR) provides body-weight support using handles, pulleys, and frames [2]. While these systems demonstrate the feasibility of robotic assistance, they present key limitations. Firstly, mechanical designs …

Modality-Specific Confidence And Uncertainty Metrics For Vision-Language Models, Sahasra Kondapalli, Poyraz An, Trung Dong, Lara Radovanovic, Xiaomin Lin

Bellini College REU Symposium (BCREUS)

Introduction and Problem Statement

Vision-Language Models (VLMs) are increasingly being integrated into high-stakes environments, such as autonomous robotics used in shared workspaces and as multimodal medical assistant systems. However, current models still have inherent uncertainties, often producing errors or false confidence in responses [1]. Such errors, when passed undetected, can cause serious issues in medical implementations. In shared workspaces, false confidence can lead to safety hazards, or disruption. Du et al. present an evaluation of uncertainty, specifically in the field of human-robot interaction [2]. Such faults are only magnified with the addition of the vision modality, thus highlighting the need …

Hacksee: Security Platform For All, Jamie Giarratana, Mohamed Eltonamly, Ben Gipalo, Robert Karam

Bellini College REU Symposium (BCREUS)

HaCKSEE intends to provide an online hardware security training platform to educators at a reduced cost. By centralizing physical experiment hardware to a provisioning service and implementing timesharing via a dynamic queue system and custom hardware, we can dramatically reduce costs while retaining a familiar workflow. HaCKSEE allows students to flash custom firmware and experiments to experiment boards and return outputs (e.g. power-consumption data) to be displayed in the development environment.

HaCKSEE offers a new approach that enables educators and trainees to get started without the high barrier-to-entry costs associated with traditional hardware security training.

(Re)Imagining Research-Practice Collaboration And Partnership: Constructivism By Way Of Interdisciplinarity, Multimodality, And Humanity, Bethany Silva, Alecia Magnifico, Laura Allen, David Baroody, Ashley Barry, Shawna Coppola, Cathy Fraser, Emily Geltz, Anne Mcquade, Christina M. Ortmeier-Hooper, Laura Smith, Donna Turco

Journal of Practitioner Research

Research-Practice Partnerships (RPPs) have become an important vehicle for educational research. By connecting researchers and educators, RPPs can couple systematic research and practical application. However, relational practices for building research collaboratives are understudied, and RPPs often reinscribe power imbalances among practitioners and researchers. With its focus on the centrality of practitioners and their knowledge, practitioner research offers possibilities for disrupting such power imbalances. In this reflective essay, our team describes our efforts to harness practitioner research’s capacity to identify and address salient school-level issues and RPPs’ power to impact a wider audience. We identify practices to build relationships, inform research …

From Inquiry To Action: Leveraging Group Level Assessment To Elevate Teacher Voice, Claire C. Underwood, Leslie Kochanowski, Abraham Underhill

Journal of Practitioner Research

This methodological paper explores the use of Group Level Assessment (GLA) (Vaughn & Lohmueller, 2014; Vaughn, 2024) as a participatory approach to practitioner inquiry within an early childhood education program. Using Cochran-Smith and Lytle’s (2009) inquiry as stance as a guiding conceptual framework, GLA is framed as a methodology that affirms educator expertise, fosters collective reflection, and generates tangible action. We document the adaptation and implementation of the GLA protocol at the Arlitt Center, a university-affiliated early childhood laboratory school committed to teacher-led professional learning. Through an adapted GLA process, teaching staff engaged in identifying barriers and opportunities related to …

An Equity Analysis Of Battery Electric Vehicles During Evacuation Considering Social And Financial Disadvantage, Divyamitra Mishra

USF Tampa Graduate Theses and Dissertations

The increasing share of battery electric vehicles (BEVs) in the transportation system is introducing new challenges to the emergency evacuation planning and management. During Hurricane Milton (2024), incidents involving BEVs, including battery fires, attributed to saltwater exposure risk, and advisories recommending relocation to higher ground, highlighted operational vulnerabilities unique to this technology. These emerging risks are likely to be experienced heterogeneously, as access to charging infrastructure, available resources, and evacuation flexibility varies across the population. This raises critical questions about how BEV-specific constraints interact with existing inequalities during evacuation. Motivated by this context, the dissertation investigated inequity in BEV evacuation …

Unveiling The Intersection Of Institutional Racial Identity And Student Loan Debt: An Analysis Of The State University System Of Florida’S Higher Education Institutions, Valerie Marie Moore

USF Tampa Graduate Theses and Dissertations

Federal student loan patterns in Florida’s State University System (SUS) from 2013/14 to 2022/23 reflect differences in institutional revenue capacity rather than individual borrowing behavior. Using data from all 12 SUS institutions, this study examined how institutional wealth and revenue composition shape student loan outcomes through both race neutral and race considerate analyses informed by Ray’s (2019) theory of racialized organizations. Overall, the SUS operates as a racialized organizational field in which inequities in funding flows, access to capital, and institutional logics sustain long term disparities in wealth and debt. Results show that borrowing levels closely track how institutions assemble …
