The Role Of Elevation As A Control On Salt Marsh-Upland Ecotones Along The Mississippi Gulf Coast, Carlton P. Anderson

Dissertations

Salt marshes are critical ecological gems that serve as habitat for many specialized species of flora and fauna, while providing a natural buffer to human populations from tropical cyclone impacts. However, rises growth of coastal populations has led to greater strain on the natural services these ecosystems provide. To better understand and project the future of coastal evolution, the physical, mechanical, and biological feedbacks between the natural and human coupled systems need to be more defined and thoroughly understood. Human encroachment towards naturally retreating shorelines will lead to coastal communities being more susceptible to nuisance tidal flooding and minor tropical …

Cognitive Aptitude As A Predictor Of Success In Associate Degree Nursing Programs, Nancy Brooks Leahy

Dissertations

Student success in nursing education is essential to supplement the healthcare workforce and sustain the delivery of safe and efficient nursing care. However, the loss of students who drop out or fail out of nursing programs is alarmingly high even though institutions have sought to identify the best candidates for admission to rigorous nursing curricula. While most nursing programs have used academic measures, such as grade point average or standardized testing to rank students for admission, these measures have not adequately captured the characteristics that students must possess to be successful. To further identify nonacademic attributes that enhance achievement, new …

The project is the result of an exploration into the characteristics and qualities of an ensemble opera, a work that derives its synergy from the interactions and collaborative efforts of memorable and varied performers. In an operatic setting, when a performer is immersed in the portrayal of a character, that nature is amplified when communicating with another role just as intentional and skillful. The sense of personality and singleness …

The Lullaby As Art Song: Engaging Repertoire For Study And Performance, Carissa Scroggins

Dissertations

When selecting repertoire, teachers of singing do not often turn to lullabies. The consensus is they are too simple in melody, texture, and harmony to warrant attention. However, this commonly held view should be reconsidered because lullabies can offer dramatic text settings. Lullabies can be divided into two categories: those for practical use and those for performance. The latter are composed as art songs written from many perspectives. They can be nationalistic, violent, frustrated, funny, and can use sleep as a metaphor for the release of death. This wealth of subject matter and variety of styles and skill levels found …

The Lived Experiences Of African American Counselors: An Exploration Of Their Reactions To Trauma Survivors, Zanovia P. Tucker

Dissertations

Nearly 83% of Americans are exposed to a traumatic event (Benjet et al., 2016). Given this, every counselor will more than likely work with trauma survivors (Trippany et al., 2004). Because of the high percentage of exposure to trauma, mental health professions who service individuals who experience trauma are at risk for secondary trauma (Ivicic & Motta, 2016), vicarious traumatization (Culver et al., 2011), and shared trauma (Hope & Edward, 2013). African American counselors have not been recognized in the counseling literature; thus their work with trauma survivors and their training experiences remain relatively unknown. Most of the research pertaining …

Behavioral Economic Modeling Of The Effects Of Symptom, Severity, And Cost On Seeking Medical Care, Mark J. Rzeszutek

Dissertations

While the United States has some of the highest healthcare spending in the world, it has some of the worst health outcomes. For example, maternal mortality in the United States is almost five times as high as in other similarly wealthy countries. It also has the highest rates of avoidable deaths. One of the reasons for this may be the cost of accessing healthcare due to privatized insurance. For example, Americans may avoid important preventive medical visits and other health screeners due to cost. While lack of health insurance has been correlated with decreased health utilization, a precise understanding of …

Evaluation Of Telehealth Training To Teach The Stimulus Identification Questionnaire And Multiple Stimulus Without Replacement, Andrea Perez

Dissertations

The field of behavioral gerontology has seen a paucity in literature within the past 15 years focused on updating training technology and teaching best practice skills to staff. Specifically, there is a need to expand the breadth of training research focus areas could more broadly the elderly population (e.g., increasing engagement), to ensure that trainings are designed to equip caregivers with the skills to be independent, and finally, given the frequent staffing challenges experienced by aging settings (Harrington et al., 2020), to explore effective and efficient training techniques that are alternatives to lengthy, in-person training modalities.

The Effects Of Token Menu Manipulations On Token Demand, Sean Regnier

Dissertations

Token economies are systems of contingencies that are designed to reinforce targeted behavior. Engaging in a targeted behavior produces conditioned stimuli that can later be exchanged for established reinforcers. A back-up reinforcer is an established reinforcer that can be acquired by exchanging the tokens. A component of token economies that has received little attention in the literature is the composition of the set of back-up reinforcers available for exchange; typically referred to as the menu. When used as part of behavior therapy, the token menu often contains a set of items that has been identified by conducting a preference assessment …

Considerations For Acquiring Excess Military Equipment By Police Leaders, Michael P. Mendenhall

From Multi-Prime To Subset Labelings Of Graphs, Bethel I. Mcgrew

Dissertations

A graph labeling is an assignment of labels (elements of some set) to the vertices or edges (or both) of a graph G. If only the vertices of G are labeled, then the resulting graph is a vertex-labeled graph. If only the edges are labeled, the resulting graph is an edge-labeled graph. The concept was first introduced in the 19th century when Arthur Cayley established Cayley’s Tree Formula, which proved that there are n^n-2 distinct labeled trees of order n. Since then, it has grown into a popular research area.

In this study, we first review several types …

Romantic Undertones In Revolutionary France: The Case For Tarare As Spark For The Revolution, Sean Robert Stephenson

Dissertations

Music is almost never cited among the causes of the French Revolution. Other arts are occasionally mentioned, such as painting and poetry, as are more obvious disciplines including philosophy and literature, which could directly disseminate the ideals of the Enlightenment. Despite this, music is only referenced insofar as how it was impacted by the Revolution, rather than how it may have played a part in the development of revolutionary sentiment. The purpose of this dissertation is to make a case for music as a cultural cause for the French Revolution by analyzing a relatively unknown opera, Tarare, by composer Antonio …

However, some schools use blended learning that would be considered successful. The purpose of this study was to explore the lived experience of principals in high-performing schools that use blended learning. A post-intentional phenomenological methodology was used to explore the lived experience of the principals in this study. The primary source of data collection was semi-structured interviews of 12 school principals. The principals in this study had common experiences …

Dolomite Stoichiometry As A Proxy For Fluid Chemistry, Cameron J. Manche

Dissertations

The origin of massive dolomites is a contentious issue in geology. Because modern dolomite is rare, interpretation of ancient dolomites requires the use of proxy resources, most of which provide ambiguous information. High-temperature dolomite synthesis experiments have shown that dolomite stoichiometry, the degree of cation ordering, and reaction rate are controlled by Mg:Ca, temperature, molarity, and salinity of the formative solution. Thus, it is posited here that dolomite stoichiometry may be a useful proxy for fluid chemistry, as are stable isotope and trace element composition of ancient dolomites. High-frequency sample intervals (cm-scale) from the Cretaceous Upper Glen Rose Formation (Comanche …

The Effects Of Multiple Exemplar Instruction On The Textual Responding Of Secondary Students With Reading Delays, Ariana D’Arms

Dissertations

A majority of eighth-grade students in the United States read below a proficient level, which means that they may have difficulty reading and comprehending grade-level text. Research indicates that older struggling readers may be missing phoneme-related skills, which limits their ability to read proficiently. Unfortunately, there is little research examining strategies for establishing such skills in older struggling readers. Multiple exemplar instruction (MEI), which has benefited young readers with phoneme-related skill deficits, is an intervention that may also be effective for older struggling readers who need phonemic skills. The purpose of the current study was to examine the effects of …

Microplankton Dynamics In The River-Dominated Mississippi Bight, Adam D. Boyette

Dissertations

The Mississippi Bight (MSB) is a river-dominated continental margin influenced by multiple large river systems, including the Mississippi River, Alabama and Tombigbee rivers via Mobile Bay, and numerous smaller rivers, creeks, and bayous. This is part of a biologically-rich ecosystem that supports the second largest fishery industry by volume in the United States. Despite our understanding of the linkages between primary production with higher trophic levels, there remains limited studies quantifying these trophic interactions in this system. Microplankton (µm) community dynamics and trophic connectivity between primary producers and heterotrophic protists represent a critical nexus influencing overall biological productivity in this …

Assessing The Real-Time Lagrangian Predictability Of The Operational Navy Coastal Ocean Model In The Gulf Of Mexico, Lea Kristen Locke

Dissertations

This study quantitatively assesses the drift predictive skill of Fleet Numerical Meteorology and Oceanography Center’s (FNMOC’s) operational ocean models which are used to support a wide range of military and civilian applications. Overall, the findings of this work support the recommendation of spatial filtering for regional-scale ocean model velocity fields used in deep-water drift applications. In conjunction with filtering, the use of a pure particle drift algorithm is suggested for short-term forecasts and a drift algorithm including a sub-grid scale, random flight, parameterization for predictions requiring extended forecast predictions.

Drift prediction skill is quantified through metrics of in-cloud percentage, distance …

Creating Appropriate Clinical Guidelines For The Bilingual Population With Acquired Brain Injuries, Sophia L. Pena

Dissertations

While there is a growing bilingual demographic in the United States, relatively little is known about treating this population should they experience a brain injury. This is a growing area of interest, as research has demonstrated that the acquisition of a second language promotes neuroplastic changes that then impact brain functioning pre- and post-brain-injury. Given bilingualism’s cognitive complexity, clinicians are left with challenges on how best to tailor treatment for brain-injured bilingual populations. Therefore, the focus of this review was to provide clinical recommendations to clinicians performing assessments with bilingual individuals with acquired brain injuries. The goal was for the …
