This study focused on this gap in the literature by examining the relationship between the frequency of communication with coworkers and job satisfaction and the moderating role of communication modality. Communication modality refers to a form of communication technology available to teleworkers, ranging from rich …

Justice And Equity In Urban Water Allocations And Conservation Solutions: A Case Study Of Non-Traditional Housing Dwellers, Matthew J. Mangoni

Master's Theses

Access to water is a human right. With droughts becoming more frequent and severe, equitable and just access to fresh water is a critical concern for policymakers and regulators. Allocation-based (AB) water rates are used widely to incentivize conservation. Previous authors document benefits of this approach for single family homes (SFH) in urban areas. People living in homeowners’ associations (HOAs) or multi-family homes and renters – commonly grouped as non-traditional housing (NTH) tend to face barriers to understanding or controlling water use and costs. This thesis investigates the equity and effectiveness of 1) AB water rate structuring and 2) a …

Unveiling The Cognitive Impact: An Exploratory Study On Food Insecurity And Value-Driven Attentional Capture, Nichole S. Hogoboom

Master's Theses

Food insecurities have been shown to lead to serious negative health outcomes such as increased risk for diabetes and obesity in adulthood, food-related mental health and behavioral issues, all of which can have a crossover effect in many areas of a person’s life. This experiment explores whether previous history of food insecurity is associated with how people allocate attention to pictures of food; whether they are prioritizing or ignoring food stimuli in their environment. We hypothesized that the severity of food insecurity experienced in childhood would correlate with attentional bias towards food images, and that how hungry or thirsty participants …

The Nature And Role Of Health Laws In The Writings Of Ellen G. White, Lehel Somogyi

Master's Theses

The Topic

Since the founding of their denomination, Seventh-day Adventists have advocated a particular concept of health based on the visions and writings of denominational co-founder Ellen G. White (1827–1915). According to her writings, certain natural laws are crucial for maintaining health. These laws are often called “the laws of health” or “the eight laws of health” and include principles such as diet, exercise, water, temperance, and hygiene. In Seventh-day Adventist circles, Ellen G. White is usually perceived as the originator of these health principles. Some scholars suggest that she simply borrowed her health principles from other contemporary health reformers. …

The Anticipation Is Killing Me! - Examining The Mediating And Moderating Relationships Between Mistreatment Anticipation And Work Engagement, Mia N. Fagan

Master's Theses

The mistreatment of workers by customers in the service industry is widespread and well-known. Although customer mistreatment is associated with negative consequences for employees, there is little knowledge about the potential consequences of the expectation of future mistreatment. The present study examined the relationship between mistreatment anticipation and work engagement and hypothesized that mistreatment anxiety would mediate the relationship between the two and that perceived organizational support (POS) would moderate the relationship between mistreatment anticipation and mistreatment anxiety. Data were collected from a sample of 183 individuals via an online survey. Results showed a significant and negative relationship between mistreatment …

The Impact Of Sea-Level Rise On Coastal Wetlands Using In-Situ Mesocosm Experiments, Landscape Modeling, And Traditional Ecological Knowledge Mapping, Kelly San Antonio

Master's Theses

Sea-level rise is an escalating threat to coastal wetlands as increased inundation and saltwater intrusion can lead to lowered productivity, decreased biomass, and plant death – and ultimately land loss. In chapter one, I detailed the interactive effects of inundation and nitrogen on two commonly found saltmarsh species, Spartina alterniflora and Spartina patens. I examined productivity and metrics to these stressors using a controlled mesocosm experiment in the western channel of the Pascagoula River, Mississippi. I found varying strategies of growth between species and differing responses between the short- and long-term. Overall Spartina alterniflora performed better with increased inundation …

Polymer-grafted cellulose (PGC) is characterized with structural analysis, solubility …

Inhibition Of Venom Gland V-Atpase Proton Pumps And Their Role In Snake Venom Acidification And Storage, Samuel Kerwin

Master's Theses

Venomous snakes are capable of storing venom for years while maintaining functionality upon injection, with no known harmful impact to their own physiology; however, the mechanisms behind this are poorly understood. Several major components of venom, most notably SVMPs, are autolytic when active, suggesting the presence of an inhibitory environment during storage to preserve venom functionality. It is hypothesized that the venom gland is continuously acidified by vacuolar rotary proton pump mechanisms (V-ATPases) localized in mitochondria-rich cells found in small concentration within the venom gland secretory epithelium, keeping the venom inert at a pH of 5.4-5.6 during the production/storage period. …
