A Test Of Criteria For Determining "Optimal" Ppor Model Reference Groups: Measuring Excess Infant Deaths In The Border Region, Alexis Nicole Ramos

Open Access Theses & Dissertations

Background: Infant mortality is one of the strongest indicators of social and economic development in all countries. Understanding infant mortality is critical for understanding the health of nations. Strategies for lowering infant death rates are needed. The Perinatal Periods of Risk Model (PPOR) is an approach that allows communities to determine when infant death and excess death is occurring by categorizing death into four perinatal categories. Excess infant deaths are determined by defining a reference group with the lowest mortality rate, and then comparing the reference group rate to other subgroups. The typical reference group has been defined as white, …

Understanding The Multidimensional Factors That Influence Hiv Testing Among Women In The Democratic Republic Of Congo, Danielle Walker

Open Access Theses & Dissertations

Approximately 37 million people worldwide are infected with the Human Immunodeficiency Virus (HIV), with the majority located in sub-Saharan Africa where women are more likely than men to become infected. Even though universal models such as the "HIV Continuum of Care" and the "Bar Before the Bars" exist that provide a context to identify barriers and tools to build the capacity for HIV testing and linkage to care, sub-Saharan Africa remains an HIV epicenter accounting for 72% of all worldwide HIV-related deaths in 2016. HIV testing rates vary significantly among many Central African countries; the DRC in particular has one …

Nutrition Label Accuracy And The Theory Of Triadic Influence: The Impact Of Knowledge On Healthy Food Choices In A Predominantly Hispanic Sample, Mosi Staudt Dane'el

Open Access Theses & Dissertations

Unhealthy food choices and the outcomes of those choices are a significant concern in the United States. Multiple governmental agencies recommend using nutrition labels to promote healthier food choices. This study investigated this claim using the theory of triadic influence to examine the efficacious use of nutrition labels on food choices. The theory of triadic influence presents a model of variables that affect food choice, including knowledge pathways on which this study focuses. Within the model, we expected increased scores on two measures of health knowledge to predict nutrition label understanding, which predict healthy food attitudes. Next, we expected that …

Environmental And Genetic Factors Affecting Antibiotic Resistance Of Extended Spectrum Î?-Lactamase Bacteria From The Rio Grande River In El Paso, Tx And Cd. Juarez, Mexico, Maria D. Fuentes

Open Access Theses & Dissertations

Background: The Rio Grande River provides a major source of potable and agricultural water for the population of the Texas/Mexico border region. Cattle farming and ranching are the most prevalent activities, which may contribute to the microbial burden of pharmaceuticals into our state's water resources. Antibiotics, presumably released into the environment by discharges originating from waste-water treatment plants, septic disposal systems, animal feeding operations and urban runoff have a definite impact on the ecosystem and may contribute to an increase in antibiotic resistance. We hypothesized that waters of the Rio Grande River contained Multi Drug Resistant Organisms (MDRO) and mobile …

Formative Evaluation Of The Health Belief Model As A Valid Theoretical Framework For "The Diabetes Garage", Renee Alexandria Orrantia

Open Access Theses & Dissertations

Background & Significance. Recent studies estimate the prevalence of diabetes among Hispanics/Latinos (H/L) to be 16.9% and 18.7% among H/L men specifically. To address this disparity, the Diabetes Garage (DG), a culturally tailored Diabetes Self-Management Education and Support (DSME/S) program, was designed to engage H/L men in diabetes self-management. Because seriousness of diabetes best predicts men’s engagement in self-care, the Health Belief Model (HBM) was chosen as the central theoretical framework. The HBM hypothesizes that the cue to action (i.e. DG) increases men’s perceived diabetes risk/severity/threat, self-efficacy in self-care, and health outcomes. Aims & Objectives. This research was aimed to …

Structure Of The Picornavirus Replication Platform: A Potential Drug Target For Inhibiting Virus Replication, Meghan Suzanne Warden

Chemistry & Biochemistry Theses & Dissertations

Picornaviruses are small, positive-stranded RNA viruses, divided into twelve different genera. Members of the Picornaviridae family cause a wide range of human and animal diseases including the common cold, poliomyelitis, foot and mouth disease, and dilated cardiomyopathy. The picornavirus genome is replicated via a highly conserved mechanism involving a presumed cloverleaf structure located at the 5’ noncoding region of the virus genome. The 5’ cloverleaf consists of three stem loops (B, C, and D) and one stem (A), which interact with a variety of virus and host cell proteins during replication. In this dissertation, human rhinovirus serotype 14 (HRV-14) SLB …

Characterizing Novel Radiologic And Pathologic Tissue-Based Risk Factors For Breast Cancer In African American Women With Benign Breast Disease, Asra N. Shaik

Wayne State University Dissertations

African American women (AAW) suffer a higher breast cancer mortality burden than women of other ethnicities in the US. More likely to be diagnosed with aggressive subtypes resistant to therapy and with rapidly fatal course than European American women (EAW), AAW may benefit greatly from earlier detection of breast cancers. However, it remains difficult to predict with a high degree of accuracy which women will develop breast cancer. Current risk assessment is especially poor for AAW, where models consistently underestimate risk in the subset of women with a prior biopsy. Risk assessment can be improved with the inclusion of new …

“Well, Don’T Walk Around Naked... Unless You’Re A Girl”: Gender, Sexuality, And Risk In Jamtronica Festival Subcultural Scenes, Kaitlyne A. Motl

Theses and Dissertations--Sociology

The purpose of this study was to explore emerging issues surrounding gendered fear, threat, and violence perpetration at music festivals – particularly events that feature a synthesis of jam band and electronic dance music acts – a genre termed jamtronica by its fans. Though gendered violence perpetration and prevention have been widely studied within other party-oriented settings (i.e., sexual violence perpetration on college campuses), very little research exists to address how wider disparities of gender and sexuality permeate a community whose members frequently claim the scene’s immunity from external inequalities.

In this three-year multi-sited ethnography, I incorporate participant observations, group …

Gender, Social Support, And Resiliency In Suicidal Ideation Among U.S. Army Soldiers, John Franklin Ambrose

Walden Dissertations and Doctoral Studies

Suicidal behaviors have continued to increase in the United States (U.S.) Army population since the beginning of the wars in Iraq and Afghanistan. Suicide rates are higher in men compared to women; yet, the rate of suicidal ideation is higher in women than men. The purpose of this study was to determine if there is a correlation between suicidal ideation and protective factors, if social support and resiliency are different for men and women within the U.S. Army population, and if gender acts as a moderating variable between suicidal ideation and protective factors. The interpersonal-psychological theory of suicidal behavior was …

Understanding Feeding Style And Young Children's Consumption Of Food, Mary W. Bean

Walden Dissertations and Doctoral Studies

Due to increased rates of childhood obesity since 2010, researchers have examined family environmental factors and family influences on children's consumption of healthy foods. While previous research has examined how factors such as food presentation and the food intake of other family members can predict a child's body mass index, there has been little research examining whether parent factors predict the amount of healthy foods children eat. This quantitative survey study examined whether certain parent factors, specifically parents' attitudes about food, parents' feeding styles, and parents' attachment styles, predicted the amount of fruits and vegetables children ate. Understanding the extent …

Reducing Congestive Heart Failure Hospital Readmissions Through Discharge Planning, Lacy Rebaka Thomas

Walden Dissertations and Doctoral Studies

Every year, thousands of congestive heart failure (CHF) patients are readmitted to the hospital within 30 days of discharge. There is a gap in practice in the care continuum of patients with CHF within the transition from hospital to home. One of the factors known to increase a patient's risk for readmission is the lack of patient engagement and self-efficacy regarding the treatment plan. The purpose of this project was to implement a transition of care practice guideline that consisted of the use of a risk identification tool, a customized care plan for patients at high risk for readmission, and …
