Sequential Monitoring Of Adaptive Randomized Clinical Trials With Sample Size Re-Estimation, Jun Yu

Dissertations and Theses (Open Access)

Clinical trials are complicated and involve human beings. Therefore, lots of ethical and efficient objectives are expected to be achieved. These objectives include maximizing the power of detecting the treatment effects, assigning more patients to the better treatments, saving the cost and time, and controlling the type I error rate. A variety of adaptive designs have been proposed to achieve different aims, among which sequential monitoring and sample size re-estimation are very popular in real clinical trials. In addition, adaptive randomization designs sequentially update the allocation probability aiming to target different allocation proportions and achieve different aims. Hu and Rosenberger …

Impacts Of Cold Weather On Health In Texas, Tsun-Hsuan Chen

Dissertations and Theses (Open Access)

Recent events with recorded low temperature and unusual snow accumulation in the United States and Europe have raised the public awareness of the potential health impacts of extreme winter weather. Excessive cold was the leading cause of weather-related death during 2006-2010 in the U.S., accounting for 63% of weather related deaths. Several studies worldwide have demonstrated that, in general, mortality rates are higher in winter compared to summer. Studies have also shown that the association between cold temperature and death vary across cities, regions and countries and is especially relevant with decreasing latitude or in regions with mild winter climate. …

Collateral Benefits Of Diabetes Self-Management Associated With Self-Administered Outpatient Parenteral Antimicrobial Therapy, Anisha P. Ganguly

Dissertations and Theses (Open Access)

Self-administered outpatient parenteral antimicrobial therapy (S-OPAT) is a self-care treatment modality in which patients requiring extended courses of intravenous antibiotics are trained to safely self-administer treatment via an indwelling catheter in their home. Many patients seen in the S-OPAT program have a diagnosis of diabetes and present with infections associated with poor glycemic control, including skin and soft-tissue infections and osteomyelitis. Given the degree of patient activation required to successfully complete the S-OPAT process, we hypothesized that participation in this self-care program may benefit patients in self-management of other chronic health conditions, such as diabetes. The study team included Anisha …

Alternative Tobacco Products & Depressive Symptoms Among Young Adults, David Marsden

Dissertations and Theses (Open Access)

The association between cigarette use and depression has been documented in many studies.

Effects Of Extreme Precipitation On Gastrointesitnal Related Hospital Admissions In Texas, Sharmila Giri

Dissertations and Theses (Open Access)

Extreme precipitation has been implicated in more than 51% of the waterborne disease outbreaks in the United States between 1948-1994. With increased incidence of extreme precipitation projected to be more likely due to ongoing climate change, the burden of waterborne disease is expected to rise even in the United States where drinking water is considered to be one of the safest in the world. In this study we aim to quantify the risk of extreme precipitation on gastrointestinal (GI) related hospital admissions by using meteorological and emergency hospital data from twelve major metropolitan statistical areas (MSA) of Texas from year …

Assessment And Findings Of The Vulnerability Index (Vi-Spdat) Survey Of Individuals Experiencing Homelessness In Travis County, Tx, Benjamin T. King

Dissertations and Theses (Open Access)

Homelessness is a significant barrier to the quality of an individual’s health. Federal housing interventions attempt to eliminate homelessness by providing varying degrees of subsidization, but available units do not currently keep pace with the scale of the problem. Coordinated Assessment is a process requirement put in place by HUD to organize and prioritize the waiting list for housing, based on community priorities. Several tools measuring health and social vulnerability, including the Vulnerability Index-Service Prioritization Decision Assistance Tool (VI-SPDAT), have become popular options for prioritizing housing resources. Such assessments currently in use are not thoroughly researched and the effects of …

Exposure To Ambient Air Pollution And Fetal Death In Harris County, Texas, Amal Rammah

Dissertations and Theses (Open Access)

The evidence from studies of maternal ambient air pollutant exposure (including O3, fine particulate matter (PM2.5) and PM2.5 metal constituents) and stillbirth is limited and equivocal. There is also limited evidence of the acute effect of temperature increases in the week preceding delivery and stillbirth. In the first investigation of ambient air pollution, temperature and stillbirth among a large cohort of women in Harris County, Texas, we obtained birth and fetal death records from 2008-2013 and estimated weekly residential levels of apparent temperature and ozone (O3), fine particulate matter (PM2.5), nitrogen dioxide (NO2) and PM2.5 metals from the local monitoring …

Does Space Matter? An Investigation Of The Spatial Variation In Gestational Weight Gain Associations With Country Of Birth Among Hispanic Women And Access To Care In Texas, Christopher R. Webb

Dissertations and Theses (Open Access)

Inadequate and excess gestational weight gain (GWG) are serious, but potentially preventable adverse pregnancy outcomes which affect as many as two-thirds of pregnant women in the United States. While location and space are associated with a variety of pregnancy outcomes, limited research has investigated potential spatial variation in GWG. The goal of this research is to improve the knowledge of how spatial geography is associated with GWG through secondary analyses of 70,000 to 160,000 birth certificate registry records for Texas mothers with a live birth delivery in 2014. Specifically, this research attempts to assess whether access to obstetrics and gynecologist …

Adverse Childhood Experiences, Depression, And Resilience In African-American Adolescents, Jamie C. Freeny

Dissertations and Theses (Open Access)

Research shows that exposure to adverse childhood experiences (ACEs) is common among adolescents; however, no studies have examined the prevalence of ACEs in a racially homogenous sample of African-American adolescents. Thus, the present study examined the cumulative and individual prevalence of ACEs in African-American adolescents. Data were collected from African-American adolescents (n = 241) who attended youth events hosted by churches in Houston, TX. An expanded ACEs tool was used to collect data. ACE scores were summed and dichotomized to 0-3 ACEs versus 4-19 ACEs because a score of four or more indicates a higher risk for adverse mental and …

Factors Associated With Civilian And Police Officer Injury During 10 Years Of Officer-Involved Shooting Incidents: A Cross-Sectional Analysis, Ellen Paddock

Dissertations and Theses (Open Access)

Purpose. Law enforcement officer-involved shootings are uncommon events in the context of encounters with the public, but extreme situations which have the potential to pose immense harm to individuals and communities. Previous research demonstrates that a large proportion of such incidents result in injury or death, most commonly to civilians, but in some cases to officers as well. However, there has been little study of what factors are associated with injury during such incidents, and whether these factors might differ for civilians compared to officers. This study examined the factors associated with both civilian and officer injury and/or fatality during …

Development And Usability Testing Of Quit4health, A Smoking Cessation Smartphone App For Young Adults, Katarzyna Czerniak

Dissertations and Theses (Open Access)

A Secondary Data Analysis For The Refinement Of Empirical Modelling For The Estimation Of Environmental Health & Safety Program Resourcing For Colleges And Universities, Seth Michael Parker

Dissertations and Theses (Open Access)

The use of potentially hazardous physical, chemical, biological, and radiological agents is inherent to the teaching, research, and services missions of any university. To manage the risks associated with these agents, it is common for universities to host environmental health & safety (EH&S) programs to protect the safety of the institution’s students, faculty, staff, and visitors. However, since EH&S programs in universities are primarily focused on prevention, it is difficult to estimate the appropriate “industry average” in terms of budget and staffing resources a particular university needs for such programs. Historically, the Campus Safety, Health, and Environmental Management Association (CSHEMA) …

Are Accounting Firms Breaching The Age Discrimination Act With The Inclusion Of Mandatory Retirement Provisions, Emily Haggard

Marketing Undergraduate Honors Theses

Age is just a number. This phrase has been murmured time after time in history. From famous movie scenes, song lyrics, pages in books, and wisdom from mothers, everyone has heard this at least once in their lives. Some joke that age only matters in wine and cheese. Some argue that age is all a limitation that the mind gives you. People are taught to never ask a woman how old she is, and as a society we celebrate certain ages such as twenty-one and sixteen, yet shun and deny those such as thirty and fifty. There are rules for …

Women As Ritualistic Agents In The Roman Catholic Church: A Comparative Theological Dialogue, Simonmary Asese Aihiokhai

Journal of the Black Catholic Theological Symposium

In sub-Saharan African religious worldview, a woman inhabits the interstitial space of connectedness. She serves as the medium for the birthing of physical and spiritual life. Today, many in the continent have embraced Christianity and many profess the Roman Catholic faith. African Catholics can contribute to the ongoing discourse on the role of women as ministerial agents in the Catholic Church. To do this, they can articulate a theology of ministry that is grounded in the religious worldview of African indigenous religions.

The Federated Colored Catholics' Chronicle, 1929‐1932: A Monitor And Barometer Of American Race Relations, Katrina Sanders

Journal of the Black Catholic Theological Symposium

This essay examines The Chronicle, the Federated Colored Catholics’ official periodical. The author argues that the short-lived publication was an educative vehicle that provided practical strategies for addressing the day-to-day racial disparities facing the larger Black community. Remnants of the social and economic issues that The Chronicle’s founder, Thomas Wyatt Turner, sought to address during the late 1920s and early 1930s remain with us today, and as such, continue to demand both attention and solutions.
