Traumatic Stress Recruits An Excitatory Orbitofrontal-Amygdala Pathway To Drive Maladaptive Aggression, Mikaela Aholt

Theses

Traumatic stress is a reliable predictor of heightened aggression, yet the mechanisms linking stress exposure to aggression remain poorly understood. The Nordman lab previously found that traumatic stress activates the posterior ventral segment of the medial amygdala (MeApv) to drive persistent increases in aggressive behavior. However, why traumatic stress would engage an aggression-promoting pathway is unclear. To address this, the inputs to the MeApv were mapped and a population of excitatory, but not inhibitory, neurons in layer 5 of the medial orbitofrontal cortex (mOFC) were identified. The OFC is classically viewed as an inhibitory brake on amygdala-driven impulses, yet emerging …

Evaluation Of Otolith Microchemistry For Identifying Walleye Stocked As Fry Or Fingerlings, Joshua Fluur

Theses

Walleye (Sander vitreus) is a popular sport fish whose populations are often supported by maintenance or supplemental stocking, with most fish stocked as fry, fingerlings, or advanced fingerlings. Evaluation of stocking efficacy is important to inform decisions regarding fish stocking rates and sizes and allocating hatchery fish to locations where maintenance or supplemental stocking is most needed. Several types of artificial tags or marks have been proven useful in the identification of stocked fish, but they often have various drawbacks. Natural chemical markers in otoliths offer several advantages compared to conventional tags or marks and can be used to identify …

The Making Of Shi'a Resistance In Afghanistan: Historical Roots, Communist Rule, And Soviet Occupation, 1978–1989, Sayed Sajjad Hojet

Theses

This thesis examines Shi'a political mobilization in Afghanistan from the 1978 Saur Revolution through the Soviet occupation, ending in 1989. It argues that Shi'a resistance was not simply a religious reaction to Marxist rule but a complex movement shaped by long-term marginalization, influenced by rival political ideas, and connected to cross-border networks in Iran. It traces how persecution under Amir Abdurrahman Khan created a system of political exclusion that shaped Shi'a collective identity before the communist takeover, and how ideologies such Marxism and Political Islam further politicized Shi'a youth in the mid-twentieth century. The PDPA's coercive policies after 1978 helped …

Deep Reinforcement Learning-Based Equitable Post Disaster Resource Allocation Incorporating Social Vulnerability, Trevor John Mogaka

Theses

Prior Deep Reinforcement Learning (DRL) approaches frame post‑disaster recovery as a sequential decision-making problem over infrastructure elements, using graph-based system models and resilience-oriented rewards. This thesis builds on an existing DRL framework by introducing a modified CDC Social Vulnerability Index (mCDC-SVI), developed using Max-min scaling, to quantify social vulnerability.A synthetic interdependent infrastructure testbed is divided into four socio‑economic regions using federal poverty and SNAP eligibility guidelines. The DRL simulation and Deep Q‑Network architecture are retrained under a multi-objective reward function that is efficiency-equity weighted (α:β). Agents are evaluated across unconstrained and constrained budget scenarios to examine how varying α and …

The Voice As A Coordinated Bodily System: Embodied Learning, Anatomy, And Vocal Pedagogy, Ge Hope Tian

The Transdisciplinary STEAM+ Journal

This reflective article examines the limitations of control-based approaches in traditional vocal training and proposes a shift toward understanding the voice as an integrated, coordinated bodily system. Drawing on personal experience, the author highlights how common instructional language - focused on outcomes such as resonance, support, and projection - often leads singers to apply excessive effort, resulting in tension, inefficiency, and vocal strain. By distinguishing between localized control and whole-body coordination, the reflection illustrates how sustainable vocal function emerges not through muscular manipulation but through balanced, dynamic organization of breath, posture, and sound. The author traces a transformative learning process …

The Secret Science Of Songs. Created By All Children Everywhere, Paul G. Morehouse Phd

The Transdisciplinary STEAM+ Journal

This field article introduces The Secret Science of Songs, a research-informed, practice-based framework that reconceptualizes songs as powerful, transdisciplinary tools in early childhood education. Drawing on over 40 years of classroom-based action research alongside established findings in cognitive science and music perception, the framework argues that young children’s engagement with songs is rooted not primarily in performance skill, but in their innate capacity to perceive and process auditory patterns in music and language. These pattern-based experiences constitute a rich aesthetic and cognitive domain through which children construct meaning, long before mastery of melody or verbal precision emerges.

The article …
