Supplemental High-Tech Augmentative And Alternative Communication Experiences: A Study On Graduate Student Self-Efficacy, Confidence, And Knowledge With Pre-Service Training, Emily Sikes

Master's Theses

Providing assessment and intervention with high-tech augmentative and alternative communication is within the scope of practice of American Speech-Language Pathologists (SLPS). Therefore, SLPs should be able to properly identify and implement assessment, intervention, and caregiver coaching strategies in this area of practice. Due to the lack of confidence ratings of current SLPs in providing assessment and intervention in AAC that is found in current research, this study was designed to find plausible solutions for which confidence ratings can be increased beginning at the graduate level of a Speech-Pathology Master’s program. The researchers sought to answer the following questions: “Do students …

Gestalt Language Processing In Accredited Communication Sciences And Disorders Programs, William Harris

Master's Theses

The language development and usage of autistic individuals has become a controversial topic in many of the disciplines and professions providing support to these individuals. As a result, two theories of language processing have been proposed. Analytical language processing suggests that children process and develop language from its most simple form, a phoneme, to its most complex form, a word or phrase. However, the theory of gestalt language processing proposes that some children may instead extract larger, more complex language such as whole words and phrases first and break it down to the simpler language. Gestalt language processing is often …

Molecular Characterization Of Stress Response In Western Honey Bee (Apis Mellifera), Faizan Tahir

Master's Theses

Honey bees are incredibly important for the reproduction of flowering plants and the sustainability of agricultural ecosystems. However, they face various stressors such as pesticides, pathogens, habitat loss, and climate change. Extensive research has been conducted to understand how bees respond to these stressors. Scientists have discovered that honey bees exhibit complex physiological and behavioral responses to stress at individual and colony levels. Stress can have a significant impact on their immune function, foraging behavior, and reproductive success (Decourtye et al., 2010). Understanding bee responses to stress is crucial for several reasons. Firstly, honey bees are vital for the pollination …

The Assessment Of Autonomic Function In Young Adults With An Elevated Risk Of Metabolic Syndrome, Ta'quoris Newsome

Master's Theses

Metabolic syndrome (MetS) is a complex medical condition defined by the co-occurrence of multiple cardiometabolic risk factors. Despite the well-defined profile of autonomic function in individuals with MetS, autonomic function in those with an elevated risk of developing MetS remains unclear. Our study aimed to shed light on the progression of cardiometabolic disease and its impact on autonomic function. To investigate, twenty participants, ten of whom were classified as having an elevated risk of developing MetS based on identification of risk factors using NCEP ATP III criteria, completed a two-visit study protocol. In the second visit, spontaneous cardiovagal baroreflex sensitivity …

Cost-Risk Analysis Of The Ercot Region Using Modern Portfolio Theory, Megan Sickinger

Master's Theses

In this work, we study the use of modern portfolio theory in a cost-risk analysis of the Electric Reliability Council of Texas (ERCOT). Based upon the risk-return concepts of modern portfolio theory, we develop an n-asset minimization problem to create a risk-cost frontier of portfolios of technologies within the ERCOT electricity region. The levelized cost of electricity for each technology in the region is a step in evaluating the expected cost of the portfolio, and the historical data of cost factors estimate the variance of cost for each technology. In addition, there are several constraints in our minimization problem to …

Chaucer’S Lists And The Parson’S Priests: Heresy, Censorship, And The Parson's Tale, Samantha Burleson

Master's Theses

Chaucer’s Parson’s Tale is a sermon on penance told by a fictional late-fourteenth-century Parson in The Canterbury Tales. What the Parson preaches is incompletely aligned with Roman Catholic orthodox beliefs, as suggested both by accusations of Lollardy elsewhere in the Canterbury Tales and heterodox features of the sermon itself. The Parson’s soteriology—the theology of how to attain salvation—invites consideration of the sermon’s potential influence from the contemporary heretical movement known as Lollardy, including the theology of John Wyclif; this theology disagreed with orthodox Catholic penitential practices.

However, despite increasing anti-Wycliffite sentiment at the turn of the fifteenth century, Chaucer’s …

Salinity Tolerance Of Flowering Rush, Butomus Umbellatus, Andrew Coomes

Master's Theses

Flowering rush is an invasive aquatic plant in North America that causes deleterious effects to native ecosystems. There are two cytotypes, a triploid and diploid, and multiple genotypes contained within the diploid cytotype currently established in the U.S. Despite its presence in river drainages connected to estuarine areas, documentation on the salinity tolerance of flowering rush is scarce. Currently, information is limited to anecdotal reports suggesting intolerance to saline conditions. A better understanding of the osmotic tolerance of this species is essential to providing insight into its’ invasive range and better inform management efforts. These studies investigated vegetative propagule germination …

How Speech-Language Pathologists Account For Self-Determination Across The Progression Of Dementia, Emilee Mcgahee

Master's Theses

Dementia diagnoses are continuing to increase, with the number of diagnoses expected to reach 231 million globally by 2050 (World Alzheimer’s Report, 2019). With this comes a greater need for Speech-Language Pathologists (SLPs) who are able to best treat those who are diagnosed. Providing person-centered and strengths-based treatment approaches for people with dementia (PWD) has been proven to increase positive engagement responses while decreasing negative engagement responses (Skrainer et al., 2007). The primary objective of this research study was to assess treatment approaches used by SLPs in dementia care setting, along with how SLPs provide person-centered dementia treatment throughout the …

Master's Theses

This study investigates gabbro-cored oceanic core complexes in the slow-spreading Mid-Atlantic Ridge (MAR) and the ultraslow spreading Southwest Indian Ridge (SWIR). Dikelets are a texture found in thin section samples from these systems that form as a result of crystal-plastic deformation. Thin section samples from the Atlantis Massif, MARK Area, and 13˚-15˚ North of the MAR and the Atlantis Bank of the SWIR were observed with petrography to find these dikelets and identify what type of dikelet is present. SEM-EDS is used to identify the mineral assemblages present in the dikelets. LA-ICP-MS is used on amphibole to determine if its …

Using Behavior Bingo To Increase Academically Engaged Behavior In A General Education Elementary School Population, Faith Elizabeth Hamilton

Master's Theses

Spending instructional and work time addressing disruptive behaviors in the classroom is a common complaint of many teachers. The literature suggests that group contingencies are beneficial for improving behavior on a classwide and individual level. The current study investigated Behavior BINGO, a group contingency intervention whose research is in its infancy, and its effectiveness on increasing academically engaged behaviors and decreasing disruptive behaviors on a classwide basis. This study utilized a nonconcurrent multiple baseline design in three 2^nd grade, general education classrooms in a public school.

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 …

Whose Woods These Are: Human-Environment Relationships Among Stakeholders Of South Mississippi's Longleaf Pine Ecosystem, Helen Greene

Master's Theses

Between 1870 and 1920, the longleaf pine belt of the southeastern United States experienced an extensive and unsustainable period of logging. In the years after the logging boom the landscape of the Southeast was reforested, but fire suppression and a preference among landowners for loblolly pine resulted in a dense and less resilient forest with reduced biodiversity. This research looks at the human geography of remnants of the longleaf pine ecosystem in South Mississippi and the nature of contemporary relationships between South Mississippi residents and this ecosystem.

In an effort to make sense of the complex relationships between people and …

The Classroom Password Group Contingency With Randomized Reinforcers, Emily Maxime

Master's Theses

From the principles of reinforcement and punishment established by operant conditioning, there have been a variety of different behavior modification methods explored. Group contingencies are one of these behavior modification procedures that can be applied at a class-wide level by teachers who are seeking to improve student behavior as a group or individually. The three types of group contingencies are independent, interdependent, and dependent group contingency. Additional components, such as randomization within a group contingency, have been seen to further the effectiveness of behavioral strategies. A novel independent group contingency that has recently been investigated and demonstrated some promise as …

Evaluating Habitat Use By Nekton In Widgeon Grass (Ruppia Maritima), Shoal Grass (Halodule Wrightii), And Unvegetated Bottom Habitats In The Grand Bay National Estuarine Research Reserve, Jessica Woodall

Master's Theses

Seagrass beds support high biodiversity and animal abundance, serve as feeding grounds for a variety of animals, offer shelter from predation, and act as a nursery habitat for juveniles. The species composition of seagrass beds can impact their use as habitat by animals. Two common species of seagrass in the Gulf of Mexico are Ruppia maritima (widgeon grass) and Halodule wrightii (shoal grass). The shallow coastal waters of the Grand Bay National Estuarine Research Reserve (NERR) support both species, but the use of each seagrass as habitat by nekton is poorly understood, which can limit management decision-making. Nekton communities were …

Comparing Effects Of Praise Rates On Classroom Behavior, Brittany Pigg

Master's Theses

High-quality academic instruction, and, in turn, student success, are correlated with effective classroom management (Gage, Scott, Hirn, & MacSuga-Gage, 2018; Johnson, 1997; Stronge, Ward, & Grant, 2011; Wang, Haertel, & Walberg, 1993). Students are spending up to 50% of their instructional time engaged in non-instructional activities such as classroom procedures, transitions, and discipline (Codding & Smyth, 2008). However, academic activities should account for at least 70% of classroom time (Little & Akin-Little, 2008). Praise, a simple classroom behavior management procedure, includes statements commending behavior and is intended to increase the future probability of the behavior that warranted praise. Behavior-specific praise …

Structural And Kinematic Investigation Of The Dadeville Complex-Brevard Zone Contact (Southern Appalachians): Polyphase Emplacement Of An Allochthonous Terrane On The Laurentian Margin, Andrew Williams

Master's Theses

The Dadeville Complex (DC) lies in the Inner Piedmont of eastern Alabama and western Georgia. The DC formed as a volcanic island arc during the Taconic orogeny (Ordovician Period) and was accreted onto Laurentia during the Acadian orogeny (Devonian-Mississippian Periods); however, the mechanism and role of accretion during the Acadian orogeny is not well constrained. Three proposed emplacement mechanisms for the DC include: (1) orogen-perpendicular translation; (2) orogen-parallel translation; (3) orogenic channel flow.

Today, the DC is a major (over 100 kilometers long) allochthonous terrane composed mostly of meta-igneous rocks. This study investigated structural fabrics and kinematic indicators in the …

Annotation Of Non-Model Species’ Genomes, Taiya Jarva

Master's Theses

The innovations in high throughput sequencing technologies in recent decades has allowed unprecedented examination and characterization of the genetic make-up of both model and non-model species, which has led to a surge in the use of genomics in fields which were previously considered unfeasible. These advances have greatly expanded the realm of possibilities in the fields of ecology and conservation. It is now possible to the identification of large cohorts of genetic markers, including single nucleotide polymorphisms (SNPs) and larger structural variants, as well as signatures of selection and local adaptation. Markers can be used to identify species, define population …

Porotic Hyperostosis And Cribra Orbitalia In The Adult Population Of Tipu, Miranda Hahn

Master's Theses

Tipu is a contact period Maya site in western Belize where a mission church and cemetery was established around AD 1560. An archaeological excavation in the 1980s recovered the remains of more than 550 individuals. In its unique location on the fringes of Spanish control, Tipu was the site of both acceptance of introduced cultural traits as well as rebellion against them. The series has been intensively studied over the last decades, but an analysis of anemia using more recently developed and widely accepted standards has not yet been completed. Therefore, I scored adults using the new widely accepted standards …

Cultural Behaviors And Their Influence On The Proximal Femur: Comparisons Of Postural Behavior, Occupation, And Subsistence-Settlement Between A Pre-Contact And Historic Sample, Joanna Klein

Master's Theses

Little is known archaeologically about the Late Woodland Schroeder Mounds mortuary group from west-central Illinois. As such, bioarchaeological data is at the forefront of archaeological problem-solving for not only the site, but the geographical area as well. Skeletal data such as proximal femur angles and activity markers contribute to the understanding of subsistence-settlement trends and postural behavior of the mortuary complex. Femoral neck version is associated with postural behaviors such as squatting and kneeling. The neck-shaft angle is linked to mobility and settlement patterns. Bicondylar angle was explored to see if behaviors had any affect. Allen’s fossa and Poirier’s facet …

Assessing The Contributions Of Proximity To Effective Instruction Delivery, Kenneth Ross

Master's Theses

Effective instruction delivery (EID) is a component of the Compliance Training for Children (CTC) Model developed by D. Joe Olmi from the School Psychology program at the University of Southern Mississippi that is designed to increase childhood compliance to adult-delivered directives. EID has been observed to be an effective strategy for increasing compliance in children (Bellipanni et al., 2013; Derieux, 2021; Ford et al., 2001; Griffin, 2007; Wimberly, 2016). Additionally, the contributions of the individual components of EID, such as demanded eye contact (Everett et al., 2005; Faciane, 2004) and contingent praise (Everett et al., 2005), have been investigated over …

Genetic Population Structure And Effective Number Of Breeders In Systems Across The Range Of The Gulf Sturgeon, Jacob Zona

Master's Theses

Gulf sturgeon (Acipenser oxyicnhus desotoi) are a large, anadromous fish belonging to an ancient lineage that diverged as early as 400 MYA. Overfishing for meat and caviar during the early 1900’s reduced their range and abundance and continued habitat destruction and mortality have limited their ability to recover, leading to their listing under the Endangered Species Act. This study uses genetic techniques to determine the effective number of breeders for multiple spawning groups of Gulf sturgeon in river systems across their range to set a baseline for tracking reproductive success of the species. Accompanying genetic information relevant to …

Identification Of Spring And Fall Spawned Eggs And The Genetic Distinction Of Gulf Sturgeon In The Choctawhatchee River, Alabama-Florida, Nicholas Lamey

Master's Theses

The Gulf Sturgeon (GS; Acipenser oxyrinchus desotoi) is a threatened subspecies of Atlantic Sturgeon (Acipenser oxyrinchus oxyrinchus) which inhabits the Gulf Coast of the United States. Prior studies of Eurasian sturgeon species and Atlantic Sturgeon have revealed the existence of a dual spawning strategy (i.e. spring and fall). The presence of a fall spawn has also been proposed for GS, but only with the support of circumstantial evidence. This study used molecular techniques to investigate seasonality of GS spawning and the possibility that this has produced unique genetic groups in the Choctawhatchee River. Mitochondrial DNA from suspected …
