Racial Socialization And Its Moderating Effects On Microaggressions, Jusiah L. Prowell

Electronic Theses and Dissertations

The purpose of this research was to examine the relationship between racial socialization, and how it mitigates the distress caused by microaggressions. Although overt racism is no longer socially acceptable, racism still occurs in a covert form called microaggressions. Research has shown that microaggressions causes negative effects on its’ victims the same as overt racism. Also, literature has shown microaggressions in the classroom and on college campuses cause feelings of isolation and inferiority in college students. Racial socialization is the process of being immersed in one’s culture to strengthen against negative factors. The construct of racial socialization is the idea …

A Systems Approach To Revenue Fluctuation In Nonprofit Human Service Organizations, Joshua James Hunter

Electronic Theses and Dissertations

Nonprofit Human Services Organizations (NPO) are normally considered to do all they can to work toward providing clients with optimal services (Bowman, 2011). What has not been considered is the possibility that NPOs sometimes allocate more revenue toward accumulating profit than toward generating services. This study used IRS 990 Forms of 150 private nonprofits from 2009 to 2010 to investigate whether NPOs did this at the peak of the recent recession, a time when there was a strong need for NPOs to increase their level of services. Results showed revenue increased 56%, services increased 1.4%, profit increased 43%, operating margin …

Weight Stigma, Cognitions, And Disordered Eating, Sarah E. Pelfrey

Electronic Theses and Dissertations

Weight stigma experiences affect people of all weights and have many negative consequences; despite this, weight stigma is still an acceptable prejudice in our society. Research has established that weight stigma is predictive of disordered eating (DE) cognitions, which are, in turn, predictive of DE behaviors. The current study explored the unique contribution DE cognitions make to DE behaviors while controlling for other DE cognitions. The DE cognitions examined in the current study were drive for thinness, weight bias internalization, and perfectionism. The DE behaviors examined were emotional eating, restrained eating, inappropriate compensatory behaviors, and binge-eating. Weight bias internalization and …

Effects Of Ponderosa Pine Ecological Restoration On Forest Soils And Understory Vegetation In Northern Arizona, Elena M. Thomas, Kenneth W. Farrish, Brian P. Oswald, Melinda G. Shaw-Faulkner, Scott R. Abella

Electronic Theses and Dissertations

The human exclusion of wildfire and overgrazing by livestock since settlement have caused dramatic changes in ponderosa pine (Pinus ponderosa Dougl ex Laws) forest ecosystems. These changes include increased numbers of tree stems, reduced understory cover and diversity, and the introduction of invasive, non-native understory species. This study evaluated the coverage and species composition of understory vegetation present in the “cool-season” (late spring and early summer) in a ponderosa pine forest on grazed and ungrazed plots that had undergone restoration treatments on three different soil/geologic parent material types near Flagstaff, Arizona, twelve years after tree thinning and grazing exclosure …

The Regulation Of Rotavirus–Infected Ht29.F8 And Ma104 Cells Treated With Arachidin 1 Or Arachidin 3, Caleb M. Witcher

Electronic Theses and Dissertations

Rotavirus (RV) infections cause severe life threatening diarrhea in young children and immunocompromised individuals. Several effective vaccines have been developed for young children but are not protective against all strains of RV, and there are no anti-RV therapeutics. Our laboratory has discovered a decrease in the number of infectious simian RV particles (SA114f) in human intestinal cell line, HT29.f8 cells with the addition of either of two stilbenoids, arachidin-1 (A1) or arachidin-3 (A3). This suggests effects on the host cell and RV replication. We examined the cellular effects of human RV strain (Wa) on a human intestinal cell line (HT29.f8) …

Therapy Dogs And The Impact On Employees In The Pediatric Medical Setting, Laine Foith

Electronic Theses and Dissertations

More than 40% of nurses reported experiencing significant burnout. Burnout is characterized by disengagement, cynicism, negative views of personal accomplishment and ability, and emotional exhaustion. The healthcare providers that experience burnout can possibly expect a decrease in ability to recognize/report errors, increase of negative feelings toward the patient, and decrease levels of patient satisfaction (Ernest, 2014). One of the ways Schub (2015) suggested to regulate burnout for employees was to provide psychosocial support to colleagues to reduce stress. This study is one of the first attempts to bridge the gap between the unknown correlation between qualitative and quantitative benefits of …

John The Solitary's Homily On The Poor In Spirit: Edition And Translation, Daniel Robert Marolf

Electronic Theses and Dissertations

This thesis examines an early fifth-century homily by John the Solitary of Apamea on Matthew 5:3, which I have called Homily on the Poor in Spirit. Mar John wrote the homily to other monks, arguing for the importance of renunciation and voluntary poverty in the life of a monk and exhorting them to develop this practice in their own lives. Although he is understood to be a prominent and influential author during his time, Mar John has received relatively little attention by modern scholarship. Neither an edition nor a translation of the Homily on the Poor in Spirit has …

Self-Efficacy In Offspring Of Mentally Ill Parents, Craig M. Motsenbocker

Electronic Theses and Dissertations

The subjective experiences of offspring of mentally ill parents have resulted in the development and absence of various components of well-being. However, there are very few studies examining levels of self-efficacy as a component of well-being within offspring of mentally ill parents. Given the evidence of lower levels of resiliency among offspring of mentally ill parents, this study proposed to evaluate the relationship between self-efficacy and offspring of mentally ill parents. Two-hundred and fifty-seven students in an introductory psychology course completed two measures assessing self-efficacy and resiliency. Among the 257 students, 27 identified with a mentally ill parent. It was …

Exploring A Novel Nf-ĸb- Inhibiting Nanoparticle For Periodontitis Therapy., Kameswara Satya Srikanth Upadhyayula

Electronic Theses and Dissertations

Periodontitis is an infection-driven inflammatory disease characterized by gingival inflammation and bone loss. The NF-ĸB signaling pathway is pivotal in osteoclastogenesis and infection-induced pro-inflammatory responses. The use of nanoparticles as a vehicle to deliver drug increases stability, loading capacity, and facilitates transmembrane transportation. The hypothesis was that a novel nanoparticle carrying therapeutic NBD inhibitory peptides (NBD-nanoparticles) will inhibit measures of periodontal disease. In this project, we tested the nanoparticles for their ability to directly inhibit osteoclastogenesis and inflammation as an original strategy for periodontitis therapy. We also tested the capability of the nanoparticles to inhibit gingival inflammation and alveolar bone …

Withaferin A Synergistically Enhances The Effects Of Paclitaxel Against Lung Cancer., Al Hassan Kyakulaga

Electronic Theses and Dissertations

Lung cancer is the leading cause of cancer-related deaths among both men and women in the U.S and worldwide. Today, paclitaxel (PAC) or taxol alongside platinum-based drugs is the most widely used agent as the first-line regimen for advanced NSCLC. However, due to toxicity, drug resistance, solubility and efficacy issues, efficacy has plateaued. In the present study, the potential of a novel plant-derived steroidal-lactone, withaferin A (WFA), for clinical use alongside PAC to improve efficacy against NSCLC was explored. The anticancer effects of PAC and WFA alone, and in combination against the in vitro cell proliferation, cell adhesion, migration and …

Treg Regulation In Periodontal Disease During Pregnancy., Aislinn Leah Hays

Electronic Theses and Dissertations

Background: Although pregnancy is prone to induce more severe periodontal inflammation and tissue damage, its mechanism remains elusive. Periodontal diseases during pregnancy are associated with adverse pregnancy outcomes including preterm birth or low birth weight. Animal models are ideal for investigating immunological mechanisms in periodontal disease. With a newly modified ligature-induced disease model, we managed to develop periodontal disease in pregnant mice and investigate the immunological mechanism of more severe symptoms during pregnancy. Hypothesis: We hypothesis that P. gingivalis infection during pregnancy will lead to a down-regulation of Treg cells, therefore causing increased inflammation and disease severity. Methods: A ligature-induced …

Spinal Cord Injury Induced Cardiac Decline And The Limitations Of Exercise., Kathryn Michele Deveau

Electronic Theses and Dissertations

There is a general consensus that the level and the severity of spinal cord injury (SCI) impacts chronic cardiac abnormalities such that high thoracic and cervical SCI are the most severely affected. Furthermore, the extreme degree of immobility/inactivity experienced by the persons with SCI has implications on cardiac decline. Yet it has been difficult to separate the relative contributions of the decentralized autonomic nervous system (ANS) and the immediate and profound inactivity to chronic cardiac abnormalities. As such, this body of work sought to characterize a contusion SCI that results in persistent CV dysfunction. Echocardiography, Dobutamine stress echocardiography and pressure …

A Novel Mra-Based Framework For The Detection Of Changes In Cerebrovascular Blood Pressure., Yitzhak Atakilt Gebru

Electronic Theses and Dissertations

Background: High blood pressure (HBP) affects 75 million adults and is the primary or contributing cause of mortality in 410,000 adults each year in the United States. Chronic HBP leads to cerebrovascular changes and is a significant contributor for strokes, dementia, and cognitive impairment. Non-invasive measurement of changes in cerebral vasculature and blood pressure (BP) may enable physicians to optimally treat HBP patients. This manuscript describes a method to non-invasively quantify changes in cerebral vasculature and BP using Magnetic Resonance Angiography (MRA) imaging.

Civic Pride Or Civic Duty? : An Examination Of Willingness To Support A Professional Sport Stadium Referendum., Alicia M. Cintron

Electronic Theses and Dissertations

Professional sport stadium subsidization is abundant across the United States, where the voting public is sometimes provided the opportunity to approve the measures through referendum. Many of these referendums are approved by the voters (Kellison & Mondello, 2014; Mondello & Anderson, 2004), despite research stating professional sport stadiums bring little to no economic benefit to a municipality (Baade, 1994, 1996; Baade & Dye, 1988a, 1990; Baade et al., 2008; Coates & Humphreys, 1999, 2002; Euchner, 1993; Zipp, 1996). Therefore, the purpose of this study was to understand what factors may influence a constituent’s willingness to support a professional sport stadium …

Intraspecific Differences In Belowground Associations And Seedling Root Morphology For The Biofuel Crop, Panicum Virgatum., Erin Renee Kinnetz

Electronic Theses and Dissertations

The perennial C₄ grass Panicum virgatum (switchgrass) is a promising bioenergy feedstock. Switchgrass is symbiotic with arbuscular mycorrhizal fungi (AMF). I examined 12 varieties of switchgrass grouped into 2 ecotypes (upland, lowland) to see if they differed in AMF abundance and root colonization using the GLBRC Variety Trials experiment. There was higher root colonization of lowland ecotype. A greenhouse experiment evaluated the role of live soil organisms in seedling establishment of 11 varieties. Live soil increased seedling survival, growth and influenced root morphology. Ecotypes differed in root architecture. Lowland developed a higher specific root length (SRL), a trait associated …
