Pape, Juan Fortea, Nicholas J. Ashton, Chinedu Udeh-Momoh, Sid E. O’Bryant, Dwight German, Florin Despa, Mark Mapstone, Henrik Zetterberg

Neurology Faculty Publications

Blood-based biomarkers continue to be explored for disease detection, monitoring of progression, and therapeutic outcomes as the diagnostic determination of Alzheimer’s Disease in Down Syndrome (DS-AD) remains challenging in clinical settings. This perspective highlights the current status of this effort. Overall, amyloid (A), tau (T), and neurodegeneration (AT[N]) blood-based biomarkers have been shown to increase with disease pathology for individuals with DS. Phosphorylated tau biomarkers (p-tau217, p-tau181) have been consistently shown to track disease progression for DS-AD and are likely good candidates for use in clinical settings. Biomarkers of inflammation (glial fibrillary acidic protein) also show promise; however, additional work …

Pro-Government Militias And Political Instability: The Consequences Of Outsourced Regime Security, Ben J.A. Leo

Theses and Dissertations--Political Science

The state is often conceptualized as an entity with a monopoly over the use of force within some set borders. Yet, more and more frequently, states allow or deliberately create friendly non-state military organizations. Five-hundred and four of these groups, known as Pro-Government Militias (PGMs), were observed between 1981 and 2014 and were present in a little more than thirty percent of country-years in that timeframe (Carey et al. 2022). Moreover, while some groups are relatively small and weak, many constitute a considerable military force within their country and beyond. For example, the Xinjiang Construction Corps in China, which maintains …

Lgbt People's Sense Of Linked Fate: Belonging And Utility, Kay Hales

Theses and Dissertations--Political Science

This is a three study dissertation. While the LGBT community is often referred to as a monolith, research suggests that it may be separate subgroups under one umbrella. Linked fate is the sense that what happens to one member of a group will affect all other group members with consequences for political behavior. While research on racial identity groups suggests that members often feel a sense of linked fate with other group members, this research has not been generalized or explored in the LGBT community. This study empirically explores whether there is a sense of linked fate in the LGBT …

Contextualizing Violence Against Women: The Influence Of Social Solidarity On Attitudes Toward Gendered Violence In Bangladesh, Tasnia Symoom

Theses and Dissertations--Political Science

Existing theories, such as Social Identity Theory, Social Dominance Theory, and the Black Sheep Effect, explain how group biases shape social attitudes but overlook the role of social contexts, such as relational dynamics, hierarchical stability, and norm violations, in influencing attitudes toward violence against women (VAW). This research addresses that gap by advancing the Selective Solidarity Theory (SST), which integrates group identity processes with contextual factors to explain selective support for perpetrators or victims based on identity and circumstance.

Using an original national survey experiment in Bangladesh, the study examines how gender, religious affiliation, and political partisanship affect public …

A Case Study In Program Evaluation: Evaluation Of A Program To Increase Physical Activity, Megan M. Harper

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Public health revolves around 3 core functions: assessment, policy development, and assurance.¹ For public health initiatives to have long-term success, we must determine if the intended effects of those programs are met in the beginning stages of program development and implementation; thus, program evaluation relates to the core function of assessment. The Centers for Disease Control and Prevention (CDC) developed a framework to facilitate this process and enable subsequent informed decisions on how to improve public health programs, which relates to policy development.² The CDC framework is comprised of 6 interconnected steps and 4 groups of standards; together, …

Understanding The Impact Of Pharmacist Prescriptive Authority On Hiv Pre-Exposure Prophylaxis At The State Level, Cameron G. King

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

HIV transmission, with relative risk reductions of up to 99%. However, real world data have revealed that even with large increases in PrEP use, new HIV diagnoses may only slightly decline. This disparity suggests that access to PrEP may be suboptimal, especially among high-risk subgroups, who are often hard to maintain on the continuum of HIV care. Pharmacists, because of their accessibility, trusted role in their communities, and growing scope of practice, could serve as an intervention point to improve access to PrEP.

How Do Couples Of Autistic Children Perceive Their Quality Of Life? A Case Study Featuring Sequential Mixed Methodology, Amanda Duncan Dr.

Theses and Dissertations--Early Childhood, Special Education, and Counselor Education

Families who have autistic children report significantly lower quality of life indicators than neurotypical families and those with other developmental disabilities (Bitsika & Sharpley, 2004; Brown et al., 2006; Charnsil & Bathia, 2010; De Sousa, 2010; Merkaj et al., 2013). However, the reports fluctuate between family members as mothers report more mental health challenges than fathers, including stress, anxiety, and depression (Dabrowska & Pstiula, 2010; Hodapp et al., 2003; Merkaj et al., 2013). Yet, these findings are based on the limited research that has been done on fathers and couples (Cheuk & Lashewicz, 2015; Osborne & Reed, 2008; Papageorgiou & …

Enhancing Communication For Individuals With Complex Communication Needs: The Critical Role Of Training And Evidence-Based Aac Strategies, Rachel H. Williams

Theses and Dissertations--Early Childhood, Special Education, and Counselor Education

Professional training and evidence-based strategies can enhance communication for individuals with complex communication needs (CCN). These individuals often require augmentative and alternative communication (AAC) systems to express themselves effectively. However, the success of AAC use depends largely on the competence of educators, speech-language pathologists, and other support personnel. The paper emphasizes the necessity of targeted professional development in strategies such as aided language modeling (ALM) and core vocabulary instruction. ALM involves modeling AAC use in natural contexts, while core vocabulary instruction focuses on teaching high- frequency, versatile words to support generative and functional communication. Integrating these strategies across settings improves …

Special Educator Persistence: Unveiling Teacher Perceptions, Janet Nutt

Theses and Dissertations--Early Childhood, Special Education, and Counselor Education

There is a continually growing shortage of special education teachers (SET). The shortage is so dire that the U.S. Bureau of Labor Statistics (2024) anticipates that as many as 35,900 new SET will be needed each year for the next decade. One of the leading factors contributing to the shortage of special educators is attrition, or any loss of teachers from their positions (Darling-Hammond, 2003; Ingersoll, 2001). Teacher persistence, therefore, is a critical concern in addressing the teacher shortage. The purpose of this mixed-methods research study is to examine the association between previously identified factors of attrition and SET decisions …

Gilead: Municipal Liability For Punitive Damages Under The Fair Housing Act, Robert G. Schwemm

Law Faculty Scholarly Articles

The 1968 Fair Housing Act (“FHA”) has always been understood to apply to local governments, which have proved to be among the most frequent and significant violators of this law, especially in their opposition to housing of particular value to racial minorities and persons with disabilities. Yet not until the Second Circuit’s decision last year in Gilead Community Services, Inc. v. Town of Cromwell did an appellate court approve an FHA-based punitive-damage award against a municipality. Before Gilead, district courts had generally blocked such awards, applying § 1983’s immunities to protect local governments and their officials from the FHA’s …
