Neuromechanical Tuning For Arm Motor Control, Russell Lee Hardesty Jr

Graduate Theses, Dissertations, and Problem Reports (ETD)

Movement is a fundamental behavior that allows us to interact with the external world. Its importance to human health is most evident when it becomes impaired due to disease or injury. Physical and occupational rehabilitation remains the most common treatment for these types of disorders. Although therapeutic interventions may improve motor function, residual deficits are common for many pathologies, such as stroke. The development of novel therapeutics is dependent upon a better understanding of the underlying mechanisms that govern movement. Movement of the human body adheres to the principles of classic Newtonian mechanics. However, due to the inherent complexity of …

Graduate Theses, Dissertations, and Problem Reports (ETD)

Overweight and obesity are prevalent and problematic conditions in the United States and worldwide, and effective weight management interventions are underutilized. Efforts to improve weight management practices have focused almost exclusively on changing physician behavior, without considering the larger healthcare context or the reciprocal patient-physician relationship. The current study explored the possibility of leveraging technology to improve the implementation of weight management clinical practice guidelines and increase patient-physician weight management discussions. 100 patients of five family medicine physicians were randomly assigned to either complete a weight management mobile application (app) prior to their primary care visit (app condition), or to …

Breaking The Chain: Evaluating The Links Between Opioid Use Disorder, Overdose, And Suicide, Amanda Nicole Stover Mph

Graduate Theses, Dissertations, and Problem Reports (ETD)

Previous research has estimated that 20–30% of individuals with opioid use disorder (OUD) have a history of both suicide attempt and unintentional opioid overdose. In 2018, more than 1.9 million adults 18 years and older had an OUD; while 1.4 million adults attempted suicide that same year (SAMHSA, 2019). The key to understanding this relationship is examining behaviors that precede these potentially fatal behaviors. One such precursory behavior is self-injury. Self-injurious behaviors (SIB) are one of the most important risk factors for future suicide (Cavanagh et al.,2003). This study has three primary objectives. The first is to conduct a systematic …

Predictors Of Self-Control During Emerging Adulthood: The Roles Of Implicit Beliefs And Early Risk, Katy L. Delong

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study explored how early adverse experiences (i.e., low socioeconomic status, household chaos, attachment insecurity) and implicit beliefs about self-control (i.e., whether self-control is a limited or nonlimited resource) were associated with trait and momentary self-control in a sample of college students. As the first study to explore these factors together, individuals’ implicit beliefs were tested as a moderator and meditator of the association between early risk and self-control. Participants (N = 214) first completed a baseline survey with the main predictors and trait self-control, followed by one week of experience sampling to assess momentary self-control, or success resisting …

The Immunological Response To Chronic Stress In Obese Mice, Matthew Corey Parsley

Graduate Theses, Dissertations, and Problem Reports (ETD)

Obesity and psychological stress are major risk factors for cardiovascular disease and have a positive correlation with vascular dysfunction. This functional deficit has been linked to a pro-inflammatory milieu, exacerbated by an upregulation of pro-inflammatory cytokines. Febuxostat, a xanthine oxidase inhibitor, has been shown to rescue vascular impairment in these models. The purpose of this study was to examine the individual and combined effects of obesity and chronic stress on neuroimmune cell populations, and assess if febuxostat is able mediate immune alterations.

Male mice (n=48) were assigned into either normal chow (lean) and high-fat diet (obese) groups. The lean animals …

Innovative Approaches To 3d Gis Modeling For Volumetric And Geoprocessing Applications In Subsurface Infrastructures In A Virtual Immersive Environment, Pragya Srivastava

Graduate Theses, Dissertations, and Problem Reports (ETD)

As subsurface features remain largely ‘out of sight, out of mind’, this has led to challenges when dealing with underground space and infrastructures and especially so for those working in GIS. Since subsurface infrastructure plays a major role in supporting the needs of modern society, groups such as city planners and utility companies and decision makers are looking for an ‘holistic’ approach where the sustainable use of underground space is as important as above ground space. For such planning and management, it is crucial to examine subsurface data in a form that is amenable to 3D mapping and that can …

Implications Of Variability Of Electromyographic Measurements For Assessing Localized Muscle Fatigue, Hamad Nasser Alasim

Graduate Theses, Dissertations, and Problem Reports (ETD)

The impact of work-related musculoskeletal disorders (WMSDs) is enormous due to a combination of direct and indirect costs associated with healthcare, lost workdays and human suffering. Because of the established relationship between Localized Muscle Fatigue (LMF) development and WMSDs, and in order to reduce and/or prevent WMSDs in workplaces, different fatigue assessment methods have been developed. Surface Electromyography (SEMG) is a commonly used LMF assessment technique. The SEMG signals are typically analyzed in time and frequency domains to predict LMF based on a relative change with respect to initial, or under no-fatigue conditions. Quantifying such change, however, relies on the …

Three Essays On The Effect Of Pain-Of-Payment On Consumers' Financial Decisions, Farnoush Reshadi

Graduate Theses, Dissertations, and Problem Reports (ETD)

In the past few years, we have witnessed a growing level of consumer debt. Although being in debt increases consumers’ stress and reduces their financial well-being, many consumers still take on high levels of debt and hold on to it even when they have financial resources to pay off the debt. Thus, it is of utmost importance to study factors that may influence consumers’ debt repayment. In this dissertation, I study consumers’ debt repayment behavior through the lens of the double-entry mental accounting theory (Prelec and Loewenstein 1998). This theory argues that consumers’ debt repayment behaviors are driven by pain-of-payment--negative …

Tree Growth And Water Use Efficiency During The Twentieth Century: From Global Trends To Local Drivers, Justin Michael Mathias

Graduate Theses, Dissertations, and Problem Reports (ETD)

The frequency and severity of extreme environmental conditions will continue to increase under global environmental change. How terrestrial plants respond to prolonged, and often novel environmental stressors, will have profound impacts on, and feedbacks with, the Earth climate system at local to continental scales. Central to these feedbacks are plant stomata, actively regulated pores on the leaves of plants that act as a control valve over the fluxes of carbon dioxide (CO₂) into the leaf during photosynthesis and water vapor (H₂O) out of the leaf during transpiration. Importantly, changes in stomatal aperture do not affect the …

Paper-Based Point-Of-Care Tools For Blood Testing, Xuefei Gao

Graduate Theses, Dissertations, and Problem Reports (ETD)

Early detection of malignant disease is crucial for timely diagnosis and effective medical intervention, which significantly increases survival rates and reduce financial burden on patients. Biomarkers are becoming increasingly important in detection of malignant diseases, because they can be employed for indicating diseases, predicting risks and monitoring the progression of diseases. In addition, biomarkers show up at early stages of diseases in human tissues and fluids (e.g., blood, urine and saliva), which shows great promise for early disease detection. In this dissertation, paper-based lateral flow strips (PLFSs) have been developed for the detection of disease biomarkers, including protein biomarkers and …

Rational Drilling Control Parameters To Reduce Respirable Dust During Roof Bolting Operations, Hua Jiang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Roof bolting has been the primary means to improve mine safety in the aspect of preventing different types of roof falls in underground mines. However, based on the published researches, underground roof bolting operators exhibit a continued risk for overexposure to high levels of respirable coal and crystalline silica dust from the roof drilling operation. Inhaling these dust can cause coal workers’ pneumoconiosis (CWP), also known as black lung. Another job-related lung disease silicosis, a disabling and even fatal and irreversible illness, could be developed through overexposure to quartz-laden dust. A recent NIOSH research shows that the quartz content in …

Adolescents’ Interpretations Of Parental Psychological Control: The Role Of Beliefs And Disapproval On Problematic Outcomes, Katelyn F. Romm

Graduate Theses, Dissertations, and Problem Reports (ETD)

Parental psychological control has consistently been found to be associated with problematic outcomes among adolescents, including substance use (Galambos, Barker, & Almeida, 2003), risky cyber behaviors (Li, Li, & Newman, 2013), problematic eating behaviors (Soenens et al., 2008), and depressive symptoms (Romm & Metzger, 2018). However, few studies have examined how adolescents reason about and react to psychological control. Recent research has suggested that adolescents vary in their beliefs about parental motivations for using psychological control, as well as their level of disapproval of psychological control (Camras et al., 2012; Kakihara & Tilton-Weaver, 2009). These cognitive factors (i.e., beliefs about …

Impact Of Sire Selection And Breed On Parasite Resistance In Sheep, Andrew Ryan Weaver

Graduate Theses, Dissertations, and Problem Reports (ETD)

Selection within and among breeds are strategies to mitigate the impact of parasitism given failing chemotherapeutics. While Texels have improved marketability compared to other parasite-resistant breeds, the mechanism by which Texels reduce fecal egg count (FEC) is unclear. The immune response to Haemonchus contortus (Hc) was compared in Texel, parasite-resistant St. Croix, and parasite-susceptible Suffolk sheep. Adult worms exposed to St. Croix- and Texel-derived peripheral blood mononuclear cells and serum in vitro had greater binding around the reproductive structures than Suffolk and worm egg release tended to be affected by breed (P = 0.09). Resistance in Texels …

The Exploration Of Nanotoxicological Copper And Interspecific Saccharomyces Hybrids, Matthew Joseph Winans Phd

Graduate Theses, Dissertations, and Problem Reports (ETD)

Nanotechnology takes advantage of cellular biology’s natural nanoscale operations by interacting with biomolecules differently than soluble or bulk materials, often altering normal cellular processes such as metabolism or growth. To gain a better understanding of how copper nanoparticles hybridized on cellulose fibers called carboxymethyl cellulose (CMC) affected growth of Saccharomyces cerevisiae, the mechanisms of toxicity were explored. Multiple methodologies covering genetics, proteomics, metallomics, and metabolomics were used during this investigation. The work that lead to this dissertation discovered that these cellulosic copper nanoparticles had a unique toxicity compared to copper.

Time-Dependent Reliability Framework For Durability Design Of Frp Composites, Rajneesh Kumar Bharil

Graduate Theses, Dissertations, and Problem Reports (ETD)

The life-cycle performance, durability, and aging characteristics of Fiber Reinforced Polymer (FRP or Structural Composites) have been of keen interest to the engineers engaged in the FRP design, construction, and manufacturing. Unlike conventional construction materials such as steel and concrete, the design guidelines to account for the aging of FRP are somewhat scattered or not available in an approved or consistent format. Loss of strength over time or aging of any structural material should be of concern to engineers as the in-service lifespan of many engineering structures is expected to exceed 100 years. Use of durability strength-reduction factors or factors …
