Item Restricted Resilience and Reality: Exploring the Lived Experiences of People Living with HIV in Texas During the COVID-19 Pandemic – A Qualitative Study.(The University of Texas at Arlington, 2025-05) Alanazi, Ahmed; Eusebius, SmallThis study investigated the lived experiences of individuals living with HIV (PLWH) in the Dallas-Fort Worth (DFW) area of Texas during the COVID-19 pandemic, using an Interpretative Phenomenological Analysis (IPA) framework. The research examined the intersection of health, social dynamics, and psychological resilience among PLWH, who faced compounded vulnerabilities due to systemic inequities and the dual public health crises of HIV and COVID-19. Through semi-structured interviews with ten participants from diverse backgrounds, the study captured the profound impacts of disrupted healthcare systems, heightened stigma, and social isolation on this marginalized population. The findings reveal that the pandemic exacerbated existing inequities in access to antiretroviral therapy (ART) and mental health services, while simultaneously highlighting the remarkable resilience of the participants. Adaptive coping mechanisms, community support, and advocacy efforts emerged as critical strategies for navigating the layered challenges of living with HIV during a global health crisis. The study identified key themes such as social isolation and estrangement, the emotional toll of the diagnosis, resilience in navigating health crises, and redefining possibilities through HIV services, with each theme branching into sub-themes that offer deeper interpretations. Participants' narratives underscore the necessity for tailored interventions that address the broad-ranging needs of PLWH, including the integration of mental health services into HIV care and the development of socially-led education campaigns to combat stigma. By focusing on the unique experiences of PLWH, this research contributes to the broader understanding of syndemic health crises, where HIV/AIDS interacts synergistically with other social, economic, and health issues, exacerbating the overall impact on affected communities. The study calls for a paradigm shift in public health policy, emphasizing the need for inclusive and intersectional approaches that prioritize equity, resilience, and community empowerment. The findings also provide actionable insights for healthcare providers, policymakers, and community organizations, advocating for robust telemedicine infrastructure, stigma reduction initiatives, and comprehensive support systems that ensure continuity of care during public health emergencies. As the global community still grapples with the lasting impacts of the COVID-19 pandemic, this study underlines the urgency of reimagining public health strategies. By centering the voices of those living at the intersection of HIV and COVID-19, it challenges existing paradigms and paves the way for innovative solutions that transcend individual health crises, offering a blueprint for more equitable, inclusive, and resilient healthcare systems. The research not only highlights the structural inequities that deepen health disparities but also illuminates the resilience and adaptive capacities of PLWH, providing a foundation for policies and practices that uphold dignity, wellbeing, and social inclusion for all.13 0Item Restricted CENTRALIZED FOUR-LEGGED ROUNDABOUT CONTROL FOR AUTOMATED VEHICLES FLOWS.(University of Akron, 2024) Alanazi, Ahmed; Yi, PingAbstract This research explores the application of Centralized Roundabout Control (CRC) to enhance the effectiveness of traffic at roundabouts under different traffic volumes. Although advantageous in practice at low traffic levels, conventional roundabouts often fail to sustain vehicle flow at higher demand levels, resulting in experiences such as queuing, increased waiting periods, increased fuel costs, and longer distances traveled. For these reasons, the CRC system was developed, and it is a traffic control solution that enhances roundabouts performance by orchestrating the entry of vehicles to reduce the waiting time and advance the traffic flow within the roundabouts. This research designed traffic at three volumes: low, medium, and high. It also used both MATLAB and VISSIM software for simulations. These simulations aimed to evaluate the performance of the CRC system in the current traffic control model, focusing on measurable performance factors such as waiting time, travel time, delays, bath throughput, fuel consumption, and stop time. The purpose of the MATLAB simulations was to measure the travel and waiting times of the vehicles crossing the roundabout. The results indicated that the application of the CRC system would lead to a reduction in the waiting and travel times for all the traffic volumes. For waiting time, the reductions were indicating that the CRC system can manage traffic even during peak hours. Travel times were also improved, indicating the practical ability of the CRC system to deal with traffic jams, enabling easy vehicle flow. These results indicate the ability of the CRC system to enhance traffic management systems by improving the drawbacks associated with the use of roundabouts in traffic. For the VISSIM simulations, five cases were reviewed: delay time, throughput and fuel consumption. All of the measures improved dramatically with the existence of the CRC system. vi For example, for Delay time, the reductions were the case with traffic volume, thus indicating the ease with which the CRC systems can handle both moderate and heavy traffic without undue delay. Throughput, or the vehicles number that were able to cross over the roundabout went , thus turning out again proving the system’s ability to foster the roundabout performance better by alleviating the problem of over congestion. There was also a reduction in the use of fuels, which is very important for commercial and ecological reasons, for example, in the CRC model. These reductions imply depreciation in the fuel wasted through proper traffic management to enhance efficiency and reduce the time for the vehicles to idle.26 0Item Restricted The Validity and Challenges of Third-Party Funding in the Saudi Arbitration Framework(Washington University, 2024-05-21) Alanazi, Ahmed; Reeves, JamesThird-party funding (TPF) is a new concept in which a third-party funds one of the disputing parties for potential share outcomes while the funded party is not obligated to repay the funds if the case is unsuccessful. In recent decades, the TPF has become more prominent for dispute parties who have faced financial obstacles to access to justice. However, the validity of the TPF agreements in Saudi Arabia remains to be determined. As the ruler of Saudi laws, Shariah prohibited agreements involving gharar (uncertainty) and usury as public policy concerns. Therefore, to break the silence surrounding TPF, this dissertation examined the validity of TPF from Shariah and Saudi perspectives. Consequently, the dissertation concluded that TPF complies with Shariah, based on the Muzara'ah partnership model, with sharing risks. This dissertation also introduces a Saudi roadmap for a TPF framework, which recommends the following (third-party funding arrangements in the Muzara'ah model comply with Saudi public policy. 2) Amendments to Saudi arbitration law require mandatory TPF disclosure to avoid conflicts of interest. 3) A code established by a supervisory body to monitor the TPF’s confidentiality and ethical practices in Saudi Arabia.32 0
