Go Talk To Your Employee: A Sequential Mediation Analysis Of Leader Communication Frequency And Employee Turnover Intent, Max Weaver Jan 2021

Go Talk To Your Employee: A Sequential Mediation Analysis Of Leader Communication Frequency And Employee Turnover Intent, Max Weaver

Electronic Theses and Dissertations

Employee turnover has significant negative costs to healthcare organizations. While leadership communication styles and quality have been empirically supported to reduce turnover intentions, our understanding of specific modalities of leader intervention is not well understood. This paper sought to understand how the specific act of communication frequency reduces turnover. Through the lens of Leader-Member Exchange (LMX) and role dynamic theories, mediating effects of LMX quality and job satisfaction were investigated to further understand this proposed relationship in a sample of healthcare workers in the Midwest/US. Results indicate that communication frequency was negatively related to turnover intent. Furthermore, while LMX and …

Improved Biochar Based Controlled-Release Nitrogen Fertilizers For Sustainable Corn Production, Robiul Islam Rubel Jan 2021

Improved Biochar Based Controlled-Release Nitrogen Fertilizers For Sustainable Corn Production, Robiul Islam Rubel

Electronic Theses and Dissertations

Nitrogen use efficiency (NUE) is an essential factor to increase crop yield. When conventional nitrogen fertilizer (e.g. Urea, Ammonium Sulphate, etc.) is applied in the field, generally over 50% of the N of these fertilizers may lose into the air due to vaporization, or run-off and leaching in rivers and lakes. The N losses lead to not only low NUE but also serious environmental problems. The consequence of N losses results in insufficient N available to meet the demand of crop growth at the growing stages. Lack of sufficient N for crop growth puts a threat of nutrient deficiency and …

Responses Of Myxobacteria To Plant-Related Chemosignals Suggests Their Roles In The Rhizobiome, Barbara Iyare Adaikpoh Jan 2021

Responses Of Myxobacteria To Plant-Related Chemosignals Suggests Their Roles In The Rhizobiome, Barbara Iyare Adaikpoh

Electronic Theses and Dissertations

In the rhizosphere, plants curate and maintain distinct rhizobiome, some of which serve as secondary defense mechanisms against pathogenic microorganisms. Additionally, in response to biotic stress, plants generate phytohormones which regulate signaling pathways to activate systemic resistance. These phytohormones contribute to the chemical space within the rhizosphere in addition to other low-molecular-weight metabolites used for cell-to-cell communication within species and across kingdoms. However, little is known about the influences of stress-related phytohormones on beneficial bacteria even though biocontrol strategies abundantly explore plant-beneficial microorganisms to manage pathogens in agricultural systems. Myxobacteria are competent predators of plant pathogens and have demonstrated responses …

Roll Down Like Water: Photography, Social Movements, And Surveillance In Memphis, Tenneessee, Andrea Morales

Electronic Theses and Dissertations

“There’s really no such thing as the ‘voiceless,’” Arundhati Roy said during a speech after earning her 2004 Sydney Peace Prize for literature. “There are only the deliberately silenced, or the preferably unheard.” These words help illuminate the tensions between dominant narrative and power, as well as photography’s role arbitrating both. This paper will explore those relationships and their impacts through existing documentary and sociological studies, but more pointedly will use the experience of making a body of work about social movements in Memphis, Tennessee. Over the last seven years, I’ve used critical race theory framework to make photographs rooting …

Electronic Theses and Dissertations

After military service is over, veterans are left to try to acclimate to their new lives. They take the lessons learned through their military career and they apply it to their daily life. One area of veteran life that remains understudied is the way that military service, combat experience specifically, alters political attitudes and behavior. The main focus of this dissertation is to understand the way that military combat alters political attitudes among military veterans. Instead of analyzing military veterans as one homogenous group, I separate veterans by combat experience. Building from the military psychology literature on combat trauma, I …


Influence Of Rage Signaling On Cellular Communication In Diabetes-Mediated Vascular Calcification, Amber Michelle Kennon Jan 2021

Influence Of Rage Signaling On Cellular Communication In Diabetes-Mediated Vascular Calcification, Amber Michelle Kennon

Electronic Theses and Dissertations

Chronic hyperglycemia is one of the main characteristics of type 2 diabetes mellitus (T2DM). With the increased prevalence of T2DM, the risk of cardiovascular complications, including heart attack or stroke, is increased. Complications linked to the vasculature are increased vascular calcification (VC) or mineral deposition within the medial layer of conducting arteries. Under calcification conditions, vascular smooth muscle cells (VSMCs) undergo an osteogenic switch to an osteoblast-like cell and begin producing bone proteins. Chronic hyperglycemia can also result in increased extracellular matrix (ECM) synthesis, accumulation, and crosslinking. One of the cell types responsible for increased ECM synthesis are ‘activated’ fibroblasts …

Investigating The Boundary Conditions Of The Fresh Start Effect, Jennifer Locander

Electronic Theses and Dissertations

The study of motivation and goal pursuit has long been of interest to various academic disciplines. Recent efforts have considered how time affects motivation and aspirational behavior. The Fresh Start Effect describes the phenomenon whereby people naturally feel more motivated to pursue goals following temporal landmarks (e.g., on Mondays). This dissertation examines a potential boundary condition of the Fresh Start Effect: the person who chooses the goal start date. The findings from six studies reveal that when goal start dates are self-chosen, motivation to pursue goals is influenced by temporal landmarks (i.e., motivation is greater on Monday). When goal start …

"No Place In American History": Remembering And Forgetting The Sultana Disaster, Elias John Baker

Electronic Theses and Dissertations

This project examines the historical memory of the Sultana steamboat disaster of April 27, 1865. The Sultana, ferrying recently-released federal prisoners, exploded north of Memphis, killing over 1,700 in the nation’s worst maritime disaster. Contemporaries interpreted the disaster through a variety of lenses, finding evidence of recalcitrant rebels, the heroism of Union soldiers, and critiques of Republican emancipationist wartime policy. Steamboat safety advocates deployed the disaster’s memory to successfully press Radical Republicans for the 1871 Steamboat Act, establishing the nation’s first maritime safety code. The disaster’s survivors gathered at reunions and published personal narratives to secure the Sultana, and the …
