Super-Fast, Super-Early: High-Frequency Oscillations May Be A Prelude To Alzheimer's Dementia In Down Syndrome, Manuel Silva-Pérez, Jeannie Chin

Faculty, Staff and Students Publications

Alzheimer's disease (AD) dementia has near full penetrance in adults with Down syndrome (DS) and is strongly linked to late-onset myoclonic epilepsy in Down syndrome (LOMEDS). However, promising biomarkers of epileptogenicity, such as high-frequency oscillations (HFOs >250 Hz), have not been studied. This study is the first to use wideband polysomnography in DS to investigate if HFOs occurred and preceded AD dementia and LOMEDS. Methods: Wideband (0.1 to 500 Hz, 2048 Hz) polysomnography was performed using the international 10–20 system. HFOs were automatically detected during slow-wave sleep, followed by manual review. Results: Fourteen individuals with DS and five age-matched euploid …

Most Alzheimer disease (AD) susceptibility genes have poorly understood roles in the central nervous system (CNS). To address this gap, we systematically characterized 100 conserved candidate AD risk genes using a cross-species strategy in the fruit fly, Drosophila melanogaster. Genes were prioritized based primarily on human functional genomic evidence. We generated custom loss-of-function alleles for each of the conserved fly orthologs. Most of the genes are expressed in the adult brain, including 24 neuron- and 13 glia-specific expression patterns. Overall, we identify 50 candidate AD risk gene homologs with requirements for CNS structure or function, including 18 whose loss of …

The Servant’S Ear: Study Of The Servant In Whom Yhwh Is Well Pleased: An Expositional Connection Of Exodus 21:5-6 And Deuteronomy 15:16-17 To The Servants Of Revelation, Warren Eugene Hoskins

Doctoral Dissertations and Projects

This dissertation undertakes an extensive investigation into the theological, historical, and literary development of the biblical servant motif. This study examines the evolution of the concept of servitude, beginning with its origins in Ancient Near Eastern (ANE) laws and culture.

It is anchored in the tradition of ear-piercing for the willing servant, as outlined in Exodus 21:5-6 and Deuteronomy 15:16-17. This research unpacks how ideas about servitude changed in the Old Testament law and how this relates to the end times and the early church, as described in Revelation. This study also compares Old Testament servant laws with those of …

In His Own Words? An Argument For Jesus As The Origin Of The Antithesis Formula In Matthew 5:21–48, Michael W. Herbert

Doctoral Dissertations and Projects

This dissertation explores the origin and authenticity of the antithesis formula, “You have heard that it was said…[OT reference]…but I say to you…,” which appears only in the Gospel of Matthew (Matt 5:21–48). This uniqueness of the antithesis formula contributes to it being one of the most intriguing yet contentious New Testament phrases. As such, there is no scholarly consensus regarding the origin of the antithesis formula. The relevant English language literature presents theories concerning the origin of the antithesis formula that generally conform to form-critical, source-critical, and redaction-critical approaches. However, this literature lacks an extended argument for this formula …

Personality Traits And Perceived Barriers: A Comparative Study Of Teacher Views On Behavior Interventions, Patricia Geiger Lee

Doctoral Dissertations and Projects

Maladaptive behaviors negatively affect both students and teachers. Students’ academic success, mental health, and safety are jeopardized by these behaviors, while teachers experience increased stress and burnout when managing them. Behavior interventions have been shown to reduce maladaptive behaviors and improve outcomes. Although most teachers agree that certain factors act as barriers to implementing behavior interventions, there is no consensus on the frequency or impact of these barriers. Guided by the Big Five Theory, this quantitative study examined how teachers’ levels of extraversion, agreeableness, conscientiousness, neuroticism, and openness were associated with differences in their perceptions of the frequency and impact …

The Call For Wailing Women In Jeremiah 9:17: Biblical Theology Of Mourning Within The Context Of Repentance, Nwabuogo N. B. Okafo

Doctoral Dissertations and Projects

The Hebrew Bible features numerous accounts of mourning that reveal it as a significant aspect of the ancient Near Eastern burial customs. Biblical mourning involves an established process of grieving the loss of a dead person by his or her family and community (Deut 34:8; 2 Sam 1:11–12). The Bible also mentions other forms of mourning besides grieving the loss of the dead. Penitential mourning is the expression of sorrow resulting from awareness of personal or corporate sin (Joel 2:12–14; Ezra 10:6). Penitential mourning could be personal or corporate (2 Sam 12:13, 16; Ezra 9:3–4). Corporate mourning involving donning of …

Truth, Trials, And Triumphs Of The Tenure Journey: Faculty Of Color In Higher Education, Derrick E. Crim

The Journal of Advancing Education Practice

Faculty of Color (FOC) face tough challenges when it comes to earning tenure and promotions. Problems like systemic inequities and biased evaluations make it harder for institutions to uphold trust and fully benefit from the diversity FOC bring. These faculty members often bring fresh perspectives shaped by their unique journeys, enriching academic spaces. Fitting into the exclusive social circles and culture of academia takes a lot of resilience and confidence. Further, issues like isolation, tokenism, and racism make things even tougher. Isolation stems from the lack of representation and supportive communities, while tokenism creates extra service demands without proper recognition. …
