Quality Of Life Among Caregivers Of Individuals With 22q11.2 Deletion Syndrome And Intellectual Disability, Sandra Garza Ochoa

Theses and Dissertations

Caregiving for a person with 22q11.2 chromosome deletion syndrome (22q) often entails dealing with medically life-threatening complications and is significantly compounded when the care recipient has comorbid 22q and intellectual disability (ID). The purpose of this study was to examine the effect of support, spirituality, and resiliency on the quality of life (QOL) of caregivers of individuals with comorbid 22q/ID to ascertain if these protective factors would reduce their caregiving burden. Study participants consisted of 469 caregivers of persons with 22q/ID who were recruited through 22q social advocacy groups. Correlational analyses, analyses of variance, and multiple regression analysis were used …

Feasibility Analysis Of Embedding Optical Fiber Sensor Into Additively Manufactured Part, Mahmudul Hasan Porag

Theses and Dissertations

The research tried to examine the viability of the embedment of optical fiber sensors in Additively built components, packaging the sensors within the components, and characterizing the sensors for sensing a specified measurement. Optical fiber sensors are popular due to their small size, resilience against electromagnetic radiation, and reliability in potentially dangerous conditions. Embedding fibers inside a product allows for the monitoring of critical areas, allowing for preemptive action in the case of a breakdown. Coupons of Inconel 718 were made using laser powder-bed fusion (LPBF), with the fabrication settings tuned to determine whether such a development was possible. After …

Disruptions In International Trade: A Perspective On Ports Of Entry And Supply Chain Resilience, Jose A. Jara Jr. Guerrero

Theses and Dissertations

United States (U.S.) ports of entry (POEs) and supply chains (SCs) have a prominent trade relationship with a growing desire to improve their operational capabilities. Though trade deals like the U.S.-Mexico-Canada (USMCA) agreement have facilitated trade between these countries, U.S. Customs and Border Protection (CBP) at POEs have also increased security inspections, following the September 11th incident, which have impacted international and global SCs. More recently, the COVID-19 pandemic has caused labor shortages at both sea and land POEs, increasing vessel and commercial vehicle congestion. These POE disruptions have also propagated into the third-party logistics (3PL) of SC networks, which …

Decision Support System To Select The Most Effective Strategies For Mitigating The Urban Heat Island Effect Using Sustainability And Resilience Performance Measures, Bahareh Bathaei

Theses and Dissertations

As climate change continues to alter the temperature of the cities, various urban heat island mitigation strategies (UHIMSs) are now needed to be employed to mitigate the effects of increasing temperatures. However, to ensure their resilience and sustainability, the effectiveness of such strategies should be evaluated using a set of criteria. According to a review of the literature, there is a need for a comprehensive model and performance assessment tool that considers the various characteristics and features that are significant in assessing whether the chosen strategies are viable candidates for minimizing the effects of urban heat island (UHI). As a …

A Darker Shade Of Gray: An Empirical Examination Of Gray Swans In The Supply Chain, Tony N.K. Lynch

Theses and Dissertations

The complexity and interconnectedness of markets creates risks in the global supply chain and may lead to various types of disruptions. Prior research in the supply chain management literature has focused on some aspect of disruption and firm performance. However, the effect of Gray Swans on various aspects of firms’ operational or financial performance is an under-research area. Understanding why managers often underestimate and overlook Gray Swans contributes to ongoing conversation of risk in the global supply chain. Gray Swans are defined as low probability risk events that if/when they occur can have a severe or catastrophic impact on a …

Field Of Dreams: Environmental Factors Contributing To The Academic And Professional Success Of Mexican-American Former Migrant Students From The Rio-Grande Valley Of South Texas, Jaime Villarreal

Theses and Dissertations

The purpose of this study was to identify protective factors contributing to the college graduation of seven Mexican-American Hispanic former migrant students from the Rio-Grande Valley of South Texas, the southernmost part of the United States that borders Mexico. I used a case study methodology to examine the real life context of a phenomenon with the data collected from the seven participants using interviews. The findings indicated that interrelated cultural, school and home environmental protective factors enhanced the resiliency of the seven participants as they navigated through their academic endeavors and ultimate college graduation. This study is important to the …

Measuring Disaster Resiliency In The Rio Grande Valley, Alma R. Provencio

Theses and Dissertations

People are now becoming more conscious of the effects of climate change. They are seeking to understand how to manage their resources and prepare for when a disaster strikes. The growing studies of disaster resilience lend that opportunity. In this spatial and temporal study, disaster resilience was measured for each census tract within the four counties of the Rio Grande Valley. Utilizing GIS tools and methods, the study examines resilience patterns between 2010 and 2017.

Results showed that even though various census tracts from each of the four counties increased in resilience from 2010 to 2017, the overall total resilience …

Roller Derby As A Form Of Self-Empowerment: An Examination Of Female Athletes' Resilience To Intimate Partner Violence, Esmeralda Castillo

Theses and Dissertations

The purpose of this study is to explore if playing roller derby can yield one more resilient to Intimate Partner Violence (IPV). IPV is a major wellness concern to our present lives. However, there are many who experience violence, yet do not develop debilitating symptoms. The subject of resilience has emerged to account for this. Resilience can be interpreted as “bouncing back” from adversity, and adapting well to sources of stress (American Psychological Association, n.d.). Sport psychologists have recognized sport as a site for the development of resilient qualities. For females, team sports offer a context to experience empowerment. The …

Resilience And Social Support Among College Students With Disabilities, Rachita Sharma

Theses and Dissertations

Since the implementation of the Americans with Disabilities Act of 1990, individuals with disabilities have found enhanced opportunities in various areas of living. The numbers of students with disabilities in institutions of postsecondary education have also increased in the past few decades; however, despite this increase, the degree completion rates of students with disabilities continue to lag in comparison to their non-disabled peers in colleges and universities. As such, most universities currently have a designated office or department of disability accommodations designed to provide academic accommodations for students with disabilities. Nonetheless, current rehabilitation research is lacking in knowledge regarding interventions …

South Padre Island Beach Management: Assessment Of Dune Restoration, Shelby Rose Bessette

Theses and Dissertations

Dune restoration is a common method of increasing coastal resilience. A dune restoration program was initiated by the City of South Padre Island, TX in 2010 consisting primarily of plantings of Sea Oats, Uniola paniculata, and Bitter Panicum, Panicum amarum and has continued approximately annually thereafter. These restoration efforts were evaluated in this study by comparing dune ecological structure and function among reference sites and restoration plots ranging in age from 2 to 5 years. Plant and animal communities were examined using a combination of quadrat sampling, funnel traps, pit-falls and sweep nets. Soil organic content and soil electric …
