Efforts to curb youth radicalization remain largely unsuccessful and pose a major challenge in the country. The existing literature on curbing youth violent extremism focuses on the use of force, while other scholars argue for a complex interplay among economic, social, political, and environmental factors. They also considered that high illiteracy, lack of religious understanding, poverty, unemployment, psychological factors, and unstable family environments contribute …

The Influence Of Circadian Rhythm Disruption And Apoe4 On The Prognosis And Progression Of Alzheimer’S Disease, Kayla Bradby

Graduate Student Dissertations, Theses, Capstones, and Portfolios

Alzheimer’s disease is characterized by cognitive decline and memory loss and is the most common form of dementia. Genetic factors such as apolipoprotein E have been significantly associated with AD development and progression, most specifically the APOE4 isoform. Emerging evidence has shown that when the body’s circadian rhythm, the 24-hour dark/light cycle, is disrupted, the potential to develop a neurodegenerative disease such as AD increases. The purpose of this literature review is to examine the relationship between AD, circadian rhythm, and the APOE isoforms. This review puts a particular emphasis on the APOE4 isoform, as it has been shown to …

Creating An Updated Risc-V Platform With Hypervisor Support, Carter A. Glatt

Masters Theses

The ability to implement virtualized environments is fundamentally based on the instruction set architecture (ISA), which implements the necessary commands to facilitate the interface between physical hardware and virtual components.

RISC-V is an open-source ISA that can be used to generate platforms that support virtualization through the use of the H-Extension ISA. Previous research into …

Shade Tree Democracy: Maintaining Peace In Post-Conflict Societies, Jaafar M. Sh Jama

Dissertations and Theses

Under what conditions does customary law contribute to maintaining peace in post-conflict societies? I study this question in the context of Somalia, a country that has lacked an effective central government since the outbreak of civil war in 1991. I argue that in the wake of civil war, traditional systems of government are capable of facilitating peace whereas governance by the modern state apparatus is often an impediment to peace. The underlying mechanisms that I argue explain the effectiveness of a traditional system of governance are that it is 1) in tune with broadly-held societal values, 2) intuitive for citizens …

Advancing The Oresat Adcs: Design & Implementation Of An Open-Source Reaction Wheel System, Chris Kane-Pardy

Dissertations and Theses

Reaction wheels provide the primary means of precision attitude control for many CubeSat attitude determination and control systems by exchanging angular momentum with the spacecraft body. As the Portland State Aerospace Society's OreSat spacecraft transitioned from a 2U to a 3U configuration, the increased spacecraft inertia reduced the attitude control authority available from the legacy reaction wheel system. This thesis addresses that challenge through the redesign of the reaction wheel system and the development of a deterministic embedded controller and experimental framework for evaluating brushless motor commutation strategies under identical operating conditions.

The redesigned system combines an analytically sized flywheel, …

We Don't See Race, We See Blue: A Case Study Of Police Unions As Racialized Organizations, Sarahfina Aubrey Peterson

Dissertations and Theses

In the late 1960s, police began to unionize. Today, they are the most well-organized labor force in the United States, with 70% to 80% of sworn officers now represented by a union. Though it has been decades, little scholarship has developed about how police unions affect policing. Much of the research that does exist uses race-neutral frames to address an organization steeped in racial history. This study aims to address this gap in scholarship, in part, by introducing race as a motivation for and explanation of organizational output.

This research applies Victor Ray's racialized organizations theory to police unions. I …

Trapped In Transition: Structural Change And Political Dynamics In Middle-Income Countries, Gabriel Duvidovich

Dissertations and Theses

The middle-income trap literature has examined why relatively few middle-income countries transition to high-income status. A range of explanations has been proposed, but the political dimension has often been overlooked. Studies that take a political perspective often focus on institutional form rather than the state’s ability to effectively implement policy. This study addresses this gap by bringing political capacity to the center of the analysis. It argues that political capacity appears important for the productive upgrading required for sustained growth in middle-income economies and shapes economic growth trajectories across countries at different income levels.

The empirical analysis uses country-period panel …

Sbirt Staff Education To Registered Nurses In The Emergency Department, Rosemary Thuet

Walden Dissertations and Doctoral Studies

Summary The project hospitals have, on average, 2,400 emergency department (ED) visits a month. Although patients receive a social screening, there are no specific assessments to determine if the person is at risk for alcohol use disorder (AUD). The lack of screening is a missed opportunity to provide a Screening, Brief Intervention and Referral to Treatment (SBIRT) assessment of over 2,400 patients a month or 48,000 people annually. Although several screening tools could be used for an SBIRT assessment, the recommendation of ED nursing leadership is to implement the tool known as the CAGE Questionnaire (Cut down, Annoyed, Guilty, and …
