Influence Of Political Affiliation On Perceived Media Bias And Trustworthiness In The Covid-19 Pandemic, Tabitha Lamberth Jan 2021

Influence Of Political Affiliation On Perceived Media Bias And Trustworthiness In The Covid-19 Pandemic, Tabitha Lamberth

College of Graduate Studies: Theses & Dissertations

Partisanship and news source attribution may influence perceived media bias and trust in COVID-19 information. This study aimed to explore how the similarity liking effect relates to political identity and perceived credibility. Our main hypothesis was that individuals would find news sources that shared their political affiliation as more trustworthy than other news sources. To test our hypothesis, 216 undergraduate students participated in a study that measured participants’ trustworthiness of a news article with randomized source attribution from a liberal, conservative, and neutral source. A 2X3 ANOVA tested the relationship between our participants’ political affiliation, measured by the 12-item Social …

Evaluating The Effects Of Self-Control Depletion On Task Persistence: A Focus On The Moderating Effects Of Performance Monitoring, Hayley Houseman Jan 2021

Evaluating The Effects Of Self-Control Depletion On Task Persistence: A Focus On The Moderating Effects Of Performance Monitoring, Hayley Houseman

College of Graduate Studies: Theses & Dissertations

Self-control is essential in day-to-day life and has important implications for goal attainment, successful living, and psychological well-being. However, self-control is known to fail when resources are depleted physically, cognitively, or emotionally, which can lead to difficulties completing important tasks. Performance monitoring, which makes a standard salient so that people can sustain their performance while attending to their goals, might buffer the loss of self-control on task performance. Overall, the purpose of this study was to experimentally examine the effects of self-control depletion and performance monitoring on task persistence. Eighty undergraduate students were recruited to participate in the study. Participants …

Numerical Approximation Of Lyapunov Exponents And Its Applications In Control Systems, Nakita K. Andrews Jan 2021

Numerical Approximation Of Lyapunov Exponents And Its Applications In Control Systems, Nakita K. Andrews

College of Graduate Studies: Theses & Dissertations

The progression of state trajectories with respect to time, and its stability properties can be described by a system of nonlinear differential equations. However, since most nonlinear dynamical systems cannot be solved by hand, one must rely on computer simulations to observe the behavior of the system. This work focuses on chaotic systems. The Lyapunov Exponent (LE) is frequently used in the quantitative studies of a chaotic system. Lyapunov exponents give the average rate of separation of nearby orbits in phase space, which can be used to determine the state of a system, e.g. stable or unstable. The objective of …

Effective Weather Messaging: Applying The Bad News Response Model To Hurricane Warnings, April S. Carr Jan 2021

Effective Weather Messaging: Applying The Bad News Response Model To Hurricane Warnings, April S. Carr

College of Graduate Studies: Theses & Dissertations

Sweeny and Shepperd (2007, 2009) proposed the Bad News Response Model (BNRM), outlining three effective responses (i.e., Watchful Waiting, Active Change, Acceptance) as a function of the perceived controllability, likelihood, and severity of bad news. In the current study, we have adapted the BNRM, previously used in health-related scenarios, to explore the relationship between message content and responses in the context of hurricane warnings. Participants viewed hurricane warnings manipulated by severity (Category 1 vs. Category 5) and the inclusion of call-to-action statements (CTAs). The present study attempted to evaluate the effects of severity and controllability on participants’ engagement in desirable …

Influence Of Increased Options On Performance Generalization Across Two Variations Of The Monty Hall Dilemma, Robert A. Southern

College of Graduate Studies: Theses & Dissertations

The Monty Hall dilemma (MHD) is a probability puzzle at which humans consistently fail to adopt the optimal winning strategy. The participant chooses between three identical doors, behind one of which is a valuable prize. After the participant makes their initial decision, the host reveals that there is nothing behind one of the two remaining doors, then asks the participant if they would like to stay with their originally selected door or switch to the remaining unopened door. The optimal choice is to switch to the previously unchosen door, which increases the probability of winning from 33% to 67%. Despite …

Supporting Student-Athlete Mental Health: Ncaa Division I Coaches' Experiences, Perceived Role, And Barriers, Kelsey Kinnamon

College of Graduate Studies: Theses & Dissertations

The opportunity for coaches to play an important role in supporting student-athlete mental health has been increasingly identified (Biggin et al., 2017; Gulliver et al., 2013; Henrikson et al., 2020). Findings suggest that coaches have the potential to help identify athletes who may benefit from mental health services, as well as foster an environment supportive of mental health and help-seeking (Bapat et al., 2009; Bissett et al., 2020). Recommendations have been set forth regarding how coaches may best engage in their role of supporting mental health, however, the literature lacks evidence of what collegiate coaches are actually doing to support …

A Semi-Active Vibration Isolator For 3d Printing On Shipboard, Mohammad Z. Shahabuddin Jan 2021

A Semi-Active Vibration Isolator For 3d Printing On Shipboard, Mohammad Z. Shahabuddin

College of Graduate Studies: Theses & Dissertations

In the recent years, additive manufacturing (AM) (aka 3D printing)-has become a viable alternative to traditional manufacturing due to its unique advantages, such as enabling the fabrication of complex geometries at reduced weight and costs as well as allowing on-site fabrication for maintenance and repair. One specific application area of the AM is the navy vessels. During extended voyages, the navy vessels likely require the convenience of on-site fabrication of the malfunctioned parts. However, the shipboard equipment suffers from a broad range of external excitations arising not only from the waves but also from the vessel’s engines, which …

Novel Quantification And Localization Of Water And Solute Transporters In The Tissues Of The Spiney Dogfish (Squalus Acanthias), Tolulope B. Ojo Jan 2021

Novel Quantification And Localization Of Water And Solute Transporters In The Tissues Of The Spiney Dogfish (Squalus Acanthias), Tolulope B. Ojo

College of Graduate Studies: Theses & Dissertations

The dogfish, Squalus acanthias is a marine cartilaginous elasmobranch found in the North Atlantic and Pacific oceans. Dogfish synthesize and excrete urea as a product of nitrogen metabolism. They also convert ammonia into urea and retain this urea, such that their plasma is isosmotic or slightly hyperosmotic to the surrounding seawater. To facilitate the regulation of body fluid and to maintain ionic concentrations and osmotic pressure, Dogfish use ion and solute transporters (e.g., NCC, UT-1) and aquaporin water channel proteins. Studies have identified some of the aquaporin genes in the elasmobranch genome, but their functions are mostly uncharacterized. Recent transcriptomic …

Teaching With Passion And Compassion In Challenging Times: A Narrative Inquiry Into Elementary Teachers' Experiences In Georgia, Erin Scroggs Jan 2021

Teaching With Passion And Compassion In Challenging Times: A Narrative Inquiry Into Elementary Teachers' Experiences In Georgia, Erin Scroggs

College of Graduate Studies: Theses & Dissertations

This study explores how teachers maintain their passion and compassion for teaching in spite of the impact of work-related challenges and subsequent obstacles upon their personal and professional lives. While much research has been conducted into teacher stress, very little has been done to connect the effects of stress on teachers’ health and passions for teaching. Abby, Nick, Passion, and Anna, four elementary school teachers from different areas, counties, schools, and school districts in the State of Georgia, participated in the study. Theoretically, I draw upon an array of works such as teaching towards freedom (Ayers, 2004, 2010, 2016), teachers …

Free-Roaming Cat Abundance Across A Habitat Gradient, Rachel E. Bird Jan 2021

Free-Roaming Cat Abundance Across A Habitat Gradient, Rachel E. Bird

College of Graduate Studies: Theses & Dissertations

There are an estimated 172 million owned and feral cats in the United States, and wildlife enthusiasts and cat owners are often at odds over how best to manage free-roaming cats. Management is needed because of the documented impacts of free-ranging cats on wildlife. Targeting these management efforts, however, is hampered by an imperfect understanding of cat distribution in the landscape. My study used game cameras and capture-recapture sampling to estimate abundance of free-roaming cats across a habitat gradient in Bulloch County, Georgia, USA. In all, I detected cats at 51% (25/49) sites with a mean of 2.1 cats per …

College Athletes' Experiences With A Lower Body Re-Injury: A Phenomenological Investigation, Samantha Holder Jan 2021

College Athletes' Experiences With A Lower Body Re-Injury: A Phenomenological Investigation, Samantha Holder

College of Graduate Studies: Theses & Dissertations

Lower extremity injuries are the most common musculoskeletal sport injuries and are an inevitable risk to sport participation (Chalmers, 2002; Dane et al., 2004; Kay et al., 2017). When an athlete sustains an injury, fear of re-injury is a salient emotion many athletes experience (e.g., Disanti et al., 2018; Kvist et al., 2005; Lentz et al., 2015). Previous research has identified fear of re-injury as a risk factor to suffering a subsequent injury (e.g., An et al., 2019; Andersen & Williams, 1988; Paterno et al., 2018; Podlog et al., 2011; Tagesson & Kvist, 2016). Epidemiology studies have highlighted that re-injuries …

Sexual Dimorphism Of Thermal Preference In Florida Scrub Lizards (Sceloporus Woodi) And Predicting Response To Climate Change In Two Rare Habitats, Sidney E. Anderson Jan 2021

Sexual Dimorphism Of Thermal Preference In Florida Scrub Lizards (Sceloporus Woodi) And Predicting Response To Climate Change In Two Rare Habitats, Sidney E. Anderson

College of Graduate Studies: Theses & Dissertations

The Florida Scrub Lizard (Sceloporus woodi) is endemic to Florida, where it inhabits fragments of xeric sandhill uplands including endangered long-leaf pine and sand pine scrub habitats. Lizards depend on a predictable range of temperatures to maximize their growth and productivity, and to do so, they shuttle among various thermal micro-environments. Thus, the spatial distribution of temperatures in the habitat is important. Habitats dominated by either high or low extremes of an organism’s preference are energetically costly and dangerous (less optimal), especially to gravid females. This study examines thermal preference of a near-threatened species that also inhabits increasingly rare habitats. …

Reclamation Of Fused Silica From Investment Shells Used For Casting Steel, Samuel L. Holt Jan 2021

Reclamation Of Fused Silica From Investment Shells Used For Casting Steel, Samuel L. Holt

College of Graduate Studies: Theses & Dissertations

Fused silica is widely used for investment casting shell molds. Fused silica shells are discarded after being used for casting one time. This is due to the transformation of fused silica to beta cristobalite above 1652℉ (900℃). To reduce cost and waste of investment casting foundries, this study is exploring a method to inhibit transformation of fused silica and reclaim it from high temperature investment casting shells. This research has employed firing to minimalize fused silica transformation to cristobalite. The phase transformation is minimalized due to sintering and coarsening of the particles during firing. Coarsening reduces surface area to volume …

Evaluation Of Supervised Deep-Learning For Improved Pneumonia Diagnosis, Andrew Kalaani Jan 2021

Evaluation Of Supervised Deep-Learning For Improved Pneumonia Diagnosis, Andrew Kalaani

College of Graduate Studies: Theses & Dissertations

Pneumonia is one of the leading causes of infections in the lung area and deaths worldwide. The mortality rate is 24.8% for patients over 70 years of age due to other health complications present along with it. In least fortunate countries, pneumonia can often times go untreated because of how cost extensive it is to diagnose, especially severe cases that cannot be seen by a plain X-ray. Other scanning methods can find the lung abnormality but are time-extensive and not cost effective. An autonomous approach however can help aid diagnosing pneumonia with a plain X-ray scan due to the structural …

The Effects Of Habitat Fragmentation On Avian Mobbing Behavior, Jada T. Daniels Jan 2021

The Effects Of Habitat Fragmentation On Avian Mobbing Behavior, Jada T. Daniels

College of Graduate Studies: Theses & Dissertations

Habitat fragmentation has negative effects on bird species diversity, as well as reproductive success of some species. However, there is little comparative information on the effect it may have on bird behavior. For example, small forest fragments are likely to have fewer bird species and individuals. This may limit the success of mobbing as an antipredator behavior because mobbing success depends on recruiting other birds to the group. This possibility has never been tested. The objective of my study is to quantify the effects of forest size on mobbing behavior in forest-dwelling birds. Mobbing behavior was elicited in 100 randomly …

Current Status Of Design And Construction Of Piles With A Pilot Hole On Rock, Charles C. Crowner Jan 2021

Current Status Of Design And Construction Of Piles With A Pilot Hole On Rock, Charles C. Crowner

College of Graduate Studies: Theses & Dissertations

Driven piles at project sites get their load bearing capacity from side friction along the driven lengths as well as from end resistance. Pilot holes is a pile driving assistance method used to aid driving displacement piles through hard/ dense layers and rock. These pilot holes can be a size smaller or larger than the pile that is to be installed. The pilot hole is first drilled down to a specific depth. The use of a pilot hole reduces the “end bearing” and “side resistance” within the drilled zone and aids the driving of the pile. This process also complicates …

Generational Cohorts And Search For B2b Service Providers, John Story

AMTP Proceedings 2021

This study explores differences in B2B search processes of members of three generational cohorts, Millennials, Generation X, and Baby Boomers. When searching for a business-to-business service provider, Millennials were significantly more likely to use an internet search, but there were no significant differences between Generation X and Baby Boomers. Although more likely to use an internet search than previous generations, Millennials were just as likely to use interpersonal information sources. These results provide insights into differentiating marketing communications to effectively reach members of different generations in business-to-business marketing.
