Electronic Theses and Dissertations
With the vast amount of quick service restaurants (QSRs) that are available to consumers in the United States (U.S.), the hospitality industry has become an integral part of Americans’ diet and lifestyle. This study examines how McDonald’s customers’ perceptions of health and nutrition, quality, and value vary demographically (gender, age, ethnicity, educational level, and body mass index [BMI]) by McDonald’s visit frequency. An online survey was employed to collect data of participants who were 18 years of age and older, McDonald’s customers, and a resident of the U.S. Of the 843 respondents who filled out the survey, 607 (72%) surveys …
Modernized Approach For Generating Micro-Layering And Macro-Heterogeneous Structures In Porous Media For Use In Transmitted-Light Method Flow Visualization Experiments, Aaron A. Jones
Electronic Theses and Dissertations
Image capturing in flow experiments has been used for fluid mechanics research since the early 1970s. Interactions of fluid flow between the vadose zone and permanent water table are of great interest to researchers because this zone is responsible for all recharge waters, pollutant transport and even irrigation efficiency for agriculture. Griffith, et al. (2011) developed an approach where constructed reproducible “geologically realistic” sand configurations are deposited in sand-filled experimental chambers or cells for light-transmitted flow visualization experiments. This method creates reproducible, reverse graded, layered (stratified) thin-slab sand chambers for visualizing multiphase flow through porous media. Reverse-graded stratification of sand …

Generalized Characteristics Of A Generic Polytope, Tommy Naugle
Generalized Characteristics Of A Generic Polytope, Tommy Naugle
Electronic Theses and Dissertations
For a smooth hypersurface S ⊂ R 2n given by the level set of a Hamiltonian function H, a symplectic form ω on R2n induces a vector field XH which flows tangent to S. By the nondegeneracy of ω, there exists a distinguished line bundle LS whose characteristics are the integral curves of XH. When S is the boundary of a smooth convex domain K˜ ⊂ R 2n, then the least action among closed characteristics of LS is equal to the Ekeland-Hofer-Zehnder capacity, a symplectic invariant. From a result due to Artstein-Avidan and Ostrover, there exists a continuous extension of …

The Impact Of Chinese Air Pollution On Match Attendance Of Chinese Super League, Wantong Fu
Electronic Theses and Dissertations
To date, environmental issues have become one of the most complex social and economic issues across the globe. Specifically, in the context of sport, the literature has considered how sport organizations may use environmental concerns as a way to connect to consumers, such as through the use of environmentally practices to help build the image of sport organizations. However, despite this lineage of studies, research which has focused on how changing environmental conditions may influence sport consumers are virtually non-existent. Such research is especially important in the case of China, where due to the rapid growth of urban areas and …

The Beam Dynamics And Beam Related Uncertainties In Fermilab Muon G-2 Experiment, Wanwei Wu
The Beam Dynamics And Beam Related Uncertainties In Fermilab Muon G-2 Experiment, Wanwei Wu
Electronic Theses and Dissertations
The anomaly of the muon magnetic moment, aμ ≡ (g-2)/2, has played an important role in constraining physics beyond the Standard Model for many years. Currently, the Standard Model prediction for aμ is accurate to 0.42 parts per million (ppm). The most recent muon g-2 experiment was done at Brookhaven National Laboratory (BNL) and determined aμ to 0.54 ppm, with a central value that differs from the Standard Model prediction by 3.3-3.6 standard deviations and provides a strong hint of new physics. The Fermilab Muon g-2 Experiment has a goal to measure aμ to unprecedented precision: 0.14 ppm, which could …
Invisible Labor: A Mixed-Method Study Of African American Women And Their Emotional Labor In The Academy, Danielle Buckingham
Invisible Labor: A Mixed-Method Study Of African American Women And Their Emotional Labor In The Academy, Danielle Buckingham
Electronic Theses and Dissertations
In this study, I examined how black women instructors and professors engage in emotional labor through performances in order to resist controlling images and stereotypes related to their race and gender. The goal was to add to the extensive literature on emotional labor and its impact on how women and people of color navigate white hegemonic institutions (Patton 2004; Harley 2007; Evans and Moore 2015). My hope is to contribute the perspectives and counter-narratives of African American women who are on the margins of race and gender. This can provide a more intersectional explanation for some of the social issues …
The Same Old Blues Crap: Selling The Blues At Fat Possum Records, Jacqueline Sahagian
The Same Old Blues Crap: Selling The Blues At Fat Possum Records, Jacqueline Sahagian
Electronic Theses and Dissertations
This thesis interrogates the marketing strategies of the Oxford, Mississippi-based record label Fat Possum, which was founded in the early 1990s by Matthew Johnson with the goal of recording obscure hill country blues artists. Fat Possum gained recognition for its raw-sounding recordings of bluesmen, including R.L. Burnside, Junior Kimbrough, Cedell Davis, and T-Model Ford, as well as its irreverent marketing techniques. Adopting the tagline “not the same old blues crap,” Fat Possum asserted that its blues were both different from and superior to all other blues music. This thesis argues that while Fat Possum claimed to be a disruptive force …

Building An Autonomous Indoor Drone System, Hunter Gossett
Electronic Theses and Dissertations
This thesis presents an indoor autonomous drone system using a self assembled drone which uses a companion computer as well as external sensors for autonomous flight. While autonomous drone systems have been around for some time, originating with the military, the vast majority of them are designed for outdoor use, because of their heavy reliance on GPS for their positioning systems. In order to achieve autonomous flight indoors we choose to use simultaneous localization and mapping (slam) as our positioning system. The contributions of this thesis is an in depth guide to the hardware and assembly of a drone system, …

Characterizing Variable Flow Pathways And Geochemical History Of Seepage Under The Mississippi River Levee: 2011, 2015, And 2016 Floods, Kaitlin Marie Voll
Characterizing Variable Flow Pathways And Geochemical History Of Seepage Under The Mississippi River Levee: 2011, 2015, And 2016 Floods, Kaitlin Marie Voll
Electronic Theses and Dissertations
Seepage beneath levees during flood stage becomes a concern when piping occurs, creating channels beneath the levee and forming sand boils where transported sediments discharge. Along the lower Mississippi River, pathways beneath the levee vary with surface geology, following deeper paths where the levee overlies channel fill deposits, and shallower paths where it overlies sand bar deposits. A preliminary investigation north of Vicksburg, MS, during the 2011 flood, demonstrated the potential for using aqueous geochemistry to differentiate sand boils forming at the end of deep and shallow flow pathways, though the study was limited to cation and trace metal analyses. …

Cumulative Disadvantage, Poverty, And The Role Of Community Capitals: A Spatial Analysis Of Uneven Development In The Multi-State Delta Region, Katrina Danielle Alford
Cumulative Disadvantage, Poverty, And The Role Of Community Capitals: A Spatial Analysis Of Uneven Development In The Multi-State Delta Region, Katrina Danielle Alford
Electronic Theses and Dissertations
Understanding space and how space impacts uneven development is crucial when examining inequalities within sociology. Uneven development perpetuates the segregation of space, highlighting disparities in power and inequalities that are rooted in spatial design and relations. Characteristics like geographic location and history have long-term influences on development, yet are not able to be easily changed within a community. Historical events have helped shape the successes and failures of communities, creating a "path dependence" that goes beyond any one individual's control. There are, however, locally-modifiable characteristics of people in spaces, such as human and social capital. These community capitals can be …

Transitioning From A Monolingual To A Dual Language Program: A Case Study Of An Elementary School, Alex Davies
Transitioning From A Monolingual To A Dual Language Program: A Case Study Of An Elementary School, Alex Davies
Electronic Theses and Dissertations
This qualitative study investigated the lived experiences of administrators, teachers, and parents from an elementary school that was in its first year of dual language transition. The majority of past studies conducted on dual language education focused on students' linguistic and academic outcomes (Lindholm-Leary, 2012). Studies investigating dual language schools' planning, policies, and classroom implementation are significantly less, and those that have, were at schools that were already functioning as dual language with the intent to examine what made the school successful (Alanis & Rodriguez, 2008; Freeman, 1996; Hunt, 2011). Through a phenomenological and case study approach, the current study …

This thesis involves examining the influence of feminism, platform and community on the fandom of Sarah J Maas (SJM) novels on the social network site Tumblr. The goals are to show how a shift to an open social network site has changed the practice of fandom and how various feminisms are applied to popular culture and learned through Tumblr. An ethnographic study and textual analysis on SJM fandom posts and interactions on Tumblr were utilized in order to reach these goals. The observations and analysis examines the data in three categories: the established characteristics of fandom on Tumblr, the characteristics …
The Ecology Of Land Managers In Riparian Restoration, Lisa Buie Clark
The Ecology Of Land Managers In Riparian Restoration, Lisa Buie Clark
Electronic Theses and Dissertations
While previous studies in restoration ecology have focused on the efficacy of direct management actions, the driving forces on management decisions (e.g., managers' characteristics or attitudes, environmental conditions) and the indirect impacts on restoration outcomes from management decisions (such as whether to collaborate) are quantified here for the first time. As a case study, I used data from 244 sites across the riparian Southwest US where the invasive shrubby tree Tamarix sp. was removed using various different methods. I surveyed and interviewed the 45 land managers who were responsible for the removal projects to determine their characteristics, attitudes, and …

Development Of A Locomotion And Balancing Strategy For Humanoid Robots, Emile Bahdi
Electronic Theses and Dissertations
The locomotion ability and high mobility are the most distinguished features of humanoid robots. Due to the non-linear dynamics of walking, developing and controlling the locomotion of humanoid robots is a challenging task. In this thesis, we study and develop a walking engine for the humanoid robot, NAO, which is the official robotic platform used in the RoboCup Spl. Aldebaran Robotics, the manufacturing company of NAO provides a walking module that has disadvantages, such as being a black box that does not provide control of the gait as well as the robot walk with a bent knee. The latter disadvantage, …
Thin-Film Lithium Niobate Photonics For Electro-Optics, Nonlinear Optics, And Quantum Optics On Silicon, Ashutosh Rao
Thin-Film Lithium Niobate Photonics For Electro-Optics, Nonlinear Optics, And Quantum Optics On Silicon, Ashutosh Rao
Electronic Theses and Dissertations
Ion-sliced thin-film lithium niobate (LN) compact waveguide technology has facilitated the resurgence of integrated photonics based on lithium niobate. These thin-film LN waveguides offer over an order of magnitude improvement in optical confinement, and about two orders of magnitude reduction in waveguide bending radius, compared to conventional LN waveguides. Harnessing the improved confinement, a variety of miniaturized and efficient photonic devices are demonstrated in this work. First, two types of compact electrooptic modulators are presented – microring modulators, and Mach-Zehnder modulators. Next, two distinct approaches to nonlinear optical frequency converters are implemented – periodically poled lithium niobate, and mode shape …
Investigating Compositional Variations Of S-Complex Near-Earth Asteroids: (1627) Ivar, Jenna Jones
Investigating Compositional Variations Of S-Complex Near-Earth Asteroids: (1627) Ivar, Jenna Jones
Electronic Theses and Dissertations
We seek to investigate the complexity and heterogeneity of the surfaces of near-Earth asteroids (NEAs). In particular, we are studying the S-complex NEAs, which account for a large portion of the observed near-Earth objects. Here we present our results for (1627) Ivar, an Amor class NEA with taxonomic type Sqw. In 2013, Ivar's large size and close approach to Earth (minimum distance 0.32 AU) provided an opportunity to observe the asteroid over many different viewing angles for an extended period of time. We collected delay-Doppler radar images and Doppler spectra using the Arecibo Observatory's 2380 MHz radar, and, by incorporating …
Electronic, Optical, And Magnetic Properties Of Graphene And Single-Layer Transition Metal Dichalcogenides In The Presence Of Defects, Mahtab Khan
Electronic Theses and Dissertations
Two-dimensional (2D) materials, such as graphene and single-layer (SL) transition metal dichalcogenides (TMDCs), have attracted a lot of attention due to their fascinating electronic and optical properties. Graphene was the first 2D material that has successfully been exfoliated from bulk graphite in 2004. In graphene, charge carriers interacting with the honeycomb lattice of carbon atoms of graphene to appear as massless Dirac fermions. Massless quasiparticles with linear dispersion are also observed in surface states of 3D topological insulators and quantum Hall edge states. My first project deals with the two-dimensional Hong-Ou-Mandel (HOM) type interference experiment for massless Dirac fermions in …
Subjective-Objective Discrepancies Among Patients With Sleep Complaints In The Patient-Centered Medical Home, Keri Bayley
Subjective-Objective Discrepancies Among Patients With Sleep Complaints In The Patient-Centered Medical Home, Keri Bayley
Electronic Theses and Dissertations
Sleep misperception – the discrepancy between objective and subjective measures of sleep – has been shown to be prevalent among patients with insomnia and may be a promising target for sleep intervention. This study examined sleep misperception in a diverse outpatient medical sample using consumer-grade wearable actigraphs (i.e., Fitbit Charge HR™). Forty-four self-identified problem sleepers aged 20 to 79 participated in the study. Participants completed sleep diaries for one week while also tracking their sleep using the Fitbit Charge HR™. After receiving a personalized sleep report based on these data, participants repeated another week of sleep assessment. Sleep misperception was …

Demanding Reduction: An Exploration Of County-Level Characteristics Associated With Areas Of Human Trafficking In Florida, Madelyn Diaz
Electronic Theses and Dissertations
Research on the prevalence of human trafficking (HT) is relatively scarce, even though more attention has been brought to this human rights issue in the past couple of decades. Widely known as a form of modern day slavery, trafficking of persons for sexual exploitative reasons to earn a profit for the trafficker occurs in every major city across the country, despite common misconceptions that it only thrives in foreign countries. To expand on limited existing literature on human trafficking, this research study explores possible correlations among areas of high violent crime rates, drug arrests, the presence of demand reduction strategies, …
State Gun Control Laws, Jacob Lafleur
State Gun Control Laws, Jacob Lafleur
Electronic Theses and Dissertations
The gun control debate has been placed at the forefront of American politics, as some of the most deadly mass shootings have happened in the last year. Much of the research on the effectiveness of gun control laws have shown inconsistent results. The purpose of the study is to compare states with stricter gun laws to states with more lax laws. This in turn will allow policy makers to identify effective strategies to implement in states that are lacking effective laws. The study examined state gun laws for all 50 states using the Gifford's Law Center to Prevent Gun Violence. …
Don't Do The Crime If You Can't Do A Man's Time: Examining Sentencing Disparities Using Offender Demographics, Vanessa Rinker
Don't Do The Crime If You Can't Do A Man's Time: Examining Sentencing Disparities Using Offender Demographics, Vanessa Rinker
Electronic Theses and Dissertations
Looking back, America has seen its fair share of differences among its population, so it should not come as a shock that sentencing disparities are a serious criminal justice issue in the United States. Each year, thousands of people are sent to Federal prisons where they receive sentences for crimes they have been convicted of committing. The United States Sentencing Commission publishes these results annually. No matter the number of persons entering the prison system on the federal level, the number of female offenders often remains about the same (8555 in 2000; 9451 in 2007; and 9302 in 2008). While …
