Leveraging Epigenomics And Transcriptomics To Develop High-Dimensional Biomarkers Of Neuroinflammation, Steven C. Pike

Dartmouth College Ph.D Dissertations

Neuroinflammation is a critical physiological phenomenon implicated in most neurological disorders, either as a cause or a consequence of pathology. Our understanding of neuroinflammation is limited by the inability to directly profile the cells of interest. Thus, developing biomarkers of neuroinflammation is clinically urgent as we know neuroinflammation correlates with patient outcomes and treatment success. The recent advances in “omics” technologies, particularly epigenomics and transcriptomics, provides the opportunity for high-dimensional profiling of biospecimens for potential biomarkers. Within this dissertation, I demonstrate that biomarkers obtained from “omics” platforms can detect neuroimmunological phenomena in clinical and preclinical settings. In chapter one, DNA …

Race Without Racism: Religious School Curricula And The Race-Neutral Legacy Of Brown, Vania Blaiklock

Scholarly Articles

Current conversations about race and equity curricula in primary and secondary education exclude examining religious curricula because of their private classification. Yet, this omission prevents us from exploring how religious curricula might mirror the legal transformation of Brown’s racial equality legacy to constitutional race neutrality. This Article brings religious curricula into these conversations by specifically linking the Court’s race-neutral transformation of Brown to the way religious curricula frame discussions about race without racism. Throughout the Article, I argue that the Court’s transformation of Brown is not just a top-down legal framework but also a bottom-up educational ideology. By making …

Art As The Prosecutor’S Weapon: The Use Of Rap Lyrics Evidence At Trial, Thompson, Mikah K., Raheem, Sierra

I then situate this within the histories of the United States and Canada and the phenomena of regionalism and independent movements. …

The Impact Of Behavior Skills Training On Secondary Math Teachers’ Use Of Evidence Based Classroom Management Strategies, Molly E. Jouflas, Kimberly Dean Dr., Peggy Hickman Dr.

Capstone Showcase

School-Wide Positive Behavior Interventions and Supports (SW-PBIS) is a research-based approach that improves student engagement, behavior, and school culture, primarily in elementary schools, but is growing in secondary schools. Secondary teachers often resist SW-PBIS due to perceptions that it’s meant for younger students and the belief that high schoolers should already know socially appropriate behavior. One significant barrier to its implementation is the lack of time and space for effective teacher training at the secondary level (Estrapala et al., 2021; Swain-Bradway et al., 2015). Behavior skills training (BST), derived from applied behavior analysis, has proven effective in training educators to …

Recommendations For Diagnosis And Treatment Of Functional Hypothalamic Amenorrhea In Females Of Reproductive Age, Monica Foster

Capstone Showcase

Hypothalamic amenorrhea (HA) accounts for approximately 30% of total cases of secondary amenorrhea in women of reproductive age. HA is defined as the absence of menses due to inadequate secretion of gonadotropin-releasing hormone (GnRH) by the hypothalamus leading to lack of secretion of gonadotropins from the anterior pituitary gland and steroid hormones from the ovaries. This feedback loop, called the hypothalamic-pituitary-gonadal (HPG) axis, regulates reproductive activity in animals and humans. When this system is disrupted in females due to a hormonal imbalance, menstrual abnormalities may emerge. Functional hypothalamic amenorrhea (FHA) is defined as the absence of menses in which anatomic …

MPA/MPP/MPFM Capstone Projects

Carl Elefante, the former president of the American Institute of Architects, famously said, “The greenest building is…one that is already built” (Elefante, 2012). Elefante articulated the environmental benefits of reuse and the significant energy costs associated with demolition and new construction. In 2022, the commercial and residential building sectors produced 31% of the United States’ greenhouse gas (GHG) emissions (EPA, 2025). A large percentage of this is tied to the production of building materials.

Beyond The Gas Tax: Evaluating Oregon’S Road Usage Charge (Orego) As A Model For Sustainable Infrastructure Funding, Gilles David Kwekam

MPA/MPP/MPFM Capstone Projects

Fuel tax revenues are declining nationwide due to electric vehicle adoption, improved fuel efficiency, and long periods without rate adjustments. This erosion has created long-term instability in transportation funding, including in Oregon, where revenue no longer aligns with road use. Road usage charges (RUCs) offer a potential replacement by charging drivers per mile traveled rather than per gallon consumed. However, their success depends less on technology and more on how programs are designed and governed.

This capstone examines which design features make RUC programs effective, using Oregon’s OReGO program as the central case. A Qualitative Comparative Analysis (QCA) comparing Oregon, …
