Evaluating Math To Mastery Using Brief Experimental Analysis Procedures, Gianna Gambera

Theses and Dissertations

Math to Mastery (MTM) is a multi-component math intervention that has demonstrated effective results in building math fluency and skill acquisition. Few studies have explored the use of brief experimental analysis (BEA) procedures to create an individualized, abbreviated MTM intervention to address skill deficits in basic math. The purpose of this current study is to analyze the utility of randomizing BEA procedures to effectively identify necessary mathematic components to create a more efficient intervention that will yield the highest math gains among participants. Researchers used an alternating treatment design with an extended analysis phase to address basic math skills. Participants …

Examining The Impact Of Financial Stress On Affect And Eating Behaviors, Ellen Hunt Steele

Theses and Dissertations

Economic pressure and concomitant financial stress have been associated with mental and physical health problems, conflict, and poorer education and employment outcomes. Moreover, financial stress can be seen in specific hardships (e.g., food insecurity) and lead to maladaptive attempts to regulate emotions stemming from financial stressors. Women may be more vulnerable to consequences of food insecurity and attempts to regulate emotions with eating than men. Thus, the current study examined the impact of a randomized financial stress induction on affect and snack food choice while accounting for the influence of food insecurity and gender. Participants included 269 validly responding individuals. …

Novel Silviculture Practices For Non-Industrial Private Forest Landowners, Darcey Alyce Collins

Theses and Dissertations

Many landowners in the southeastern United States have invested in southern yellow pine plantations and managed them using traditional management schemes. However, non-industrial private forest landowners often have goals and challenges that make traditional management less desirable or possible. This thesis contains two projects that offer potential solutions for these landowners. The first project is a management option for landowners with small parcels that wish to manage pine plantations and proposes low-density management paired with crown lifting for the production of saw logs without commercial thinning entries. The second proposes a method for incorporating mixed-species management into already existing plantations. …

X-Ray Vision At Action Space Distances: Depth Perception In Context, Nate Phillips

Theses and Dissertations

Accurate and usable x-ray vision has long been a goal in augmented reality (AR) research and development. X-ray vision, or the ability to comprehend location and object information when such is viewed through an opaque barrier, would be imminently useful in a variety of contexts, including industrial, disaster reconnaissance, and tactical applications. In order for x-ray vision to be a useful tool for many of these applications, it would need to extend operators’ perceptual awareness of the task or environment. The effectiveness with which x-ray vision can do this is of significant research interest and is a determinant of …

The purpose of this series of studies was to determine the effects of injecting 50 μL of different dosages of the PECV into Hy-Line W-36 layer hatching eggs on the hatchability and characteristics of the hatchlings, and on the livability and characteristics of the chicks through 21 d …

Behavioral And Histological Inflammatory Analysis Of A Single, Mild Traumatic Brain Injury And Repeated Subconcussive Brain Injury Using A Rodent Model., Anna Marie Clay

Theses and Dissertations

Subconcussive (SC) impacts have become a growing concern within the neuroscience community regarding the immediate and long-lasting effects of sports-related injuries. While a single low-level impact, i.e., a subconcussion, may not cause cerebral perturbations, it has been increasingly recognized that repeated SC exposure can induce deleterious effects. Therefore, determining the lower limits of systematic perturbation resulting from multiple SC impacts is of critical importance in expanding our understanding of cerebral vulnerability and recovery. Currently, there is a lack of correlation between a mild traumatic brain injury (mTBI) and repeated SC impacts with respect to injury biomechanics. Moreover, the cumulative threshold …

Evaluating The Effectiveness Of Behavioral Skills Training To Increase Stranger Safety Skills In Adults With Intellectual Disabilities, Lauren M. Meyers

Theses and Dissertations

Several research studies have suggested that individuals with ID are at an increased risk of being a target of victimization (Hughes et al., 2012; Wilson et al.,1992). Therapists, caregivers, primary care providers, and school staff may also undervalue or fail to teach critical safety skills early in childhood or in the adolescent years, which increases risk of victimization in adulthood (Dembo et al., 2018). The purpose of the current study was to evaluate the effectiveness, generalizability, and maintenance of the use of behavior skills training to teach stranger safety skills to young adults with intellectual disabilities. Specifically, a two-step safety …

A Test Of The Interpersonal Theory Of Suicide In Black College Students Using Multigroup Confirmatory Factor Analysis, Anisha L. Thomas

Theses and Dissertations

The Interpersonal Theory of Suicide (ITS) has garnered much attention in the literature. Studies that have examined ITS among Black and other racially/ethnically diverse populations continue to be met with inconsistent results. This suggests the need to confirm measurement equivalence across populations to improve accuracy in identifying individuals who are at increased risk for suicide. This study examined measurement invariance of the Interpersonal Needs Questionnaire (INQ) and Acquired Capability for Suicide Scale (ACSS) across White and Black racial groups using two college student samples. Multigroup confirmatory factor analyses were conducted from Sample 1, a group of 1,019 (86.8% White) students …

Modeling Supercritical Fluids And Fabricating Electret Films To Address Dielectric Challenges In High-Power-Density Systems, Farhina Haque

Theses and Dissertations

Wide bandgap (WBG) devices and power electronic converters (PEC) that enable the dynamic control of energy and high-power density designs inevitably contain defects including sharp edges, triple points, and cavities, which result in local electric field enhancements. The intensified local electric stresses cause either immediate dielectric breakdown or partial discharge (PD) that erodes electrical insulators and accelerates device aging. With the goal of addressing these dielectric challenges emerging in power-dense applications, this dissertation focuses on 1) modeling the dielectric characteristics of supercritical fluids (SCFs), which is a new dielectric medium with high dielectric strength and high cooling capability; and 2) …

Training Future Teachers To Conduct Trial-Based Functional Analyses Using Virtual Video Modeling And Video Feedback, Jasmine R. Sorrell

Theses and Dissertations

Students commonly engage in problem behaviors, yet teachers report handling difficult behavior as their biggest challenge. Some research over the last few decades has used functional analyses (FAs) to determine the function of student’s problem behavior and then developed functional-based interventions based on the FA findings. Despite the success of the studies, research has indicated traditional FA methodologies are not always feasible for teachers and/or schools. Therefore, a need still exists to develop better and more efficient ways to train teachers how to conduct FAs in the classroom. Thus, the purpose of the current study was to evaluate the effectiveness …

Theses and Dissertations

I examined the effects of temperature (25, 30, and 35°C) on growth, standard metabolic rate (SMR), and lower dissolved oxygen tolerance (LDOT) of juvenile Speckled Peacock Bass Cichla temensis. Fish were acclimated to 150-L aquaria for 7 weeks before the growth, SMR, and LDOT experiments. The growth study lasted 58 days and fish acclimated to 25 and 30°C displayed similar growth rates, while fish acclimated to 35°C had very poor growth rates. The SMR and LDOT experiments were performed using intermittent respirometers. Fish acclimated to 25°C had the lowest SMR, followed by 30°C, and finally 35°C. The highest LDOT …

Effectiveness Of Food-Grade Coating Treated Nets After Various Drying Methods At Controlling Mite Growth On Dry-Cured Hams, Sadie White

Theses and Dissertations

Tyrophagus putrescentiae, known as the ham mite, is the most difficult pest to control in the dry-cured ham industry. Food-grade propylene glycol coated nets have been studied as an alternative to conventional mite infestation treatments but were heavy and costly to ship. This study aimed to increase the ease of use of the coated nets via drying. Three drying treatments: oven dried for 7 min (OD7m), oven dried for 20 min (OD20m), and counter dried for 24 h (CD24h), were tested to determine the efficacy at controlling mites as well as the mechanical properties of the nets and sensory characteristics …

Ex Vivo Biomechanical Evaluation Of A Novel Screw For Tibial Plateau Leveling Osteotomy, William Seth Kettleman

Theses and Dissertations

Twelve pairs of cadaveric pelvic limbs were harvested from skeletally mature dogs. Tibias were randomly assigned pairwise to two study groups: locking buttress screw fixation (LBS) and bone-screw-fastener fixation (BSF). A tibial plateau leveling osteotomy (TPLO) was performed. Each specimen was positioned in a servohydraulic testing machine to simulate physiological orientation and loading at the mid-point of the stance phase at the walk. Cyclic loading was performed for 30,000 cycles at 4Hz with a peak-load of 1000N. The cyclic test was then continued by stepwise increasing the peak-load at a rate of 75N per 500 cycles until failure of the …

The use of traditional construction materials is responsible for a higher percentage of global greenhouse gas emissions when compared to the use of sustainable materials in the construction industry. The substitution of current building materials with sustainable materials is essential to reduce greenhouse gas emissions and positively influence climate change when the current construction demand in the world is considered. Wood is one of the primary environmentally friendly construction materials in regard to high carbon storage and low carbon emissions. …

The Effects Of Incorporating 0-500 M Srh Into The Violent Tornado Parameter, Jay Palmer Roberts

Theses and Dissertations

Between 2011-2021, violent tornadoes accounted for an average of 65% of all tornado-related fatalities. The Violent Tornado Parameter (VTP), created in 2018, attempts to address this forecast problem but has issues with false alarms. Storm Relative Helicity has historically been used in tornado forecasting. Recent studies have shown the 0-500 m effective layer SRH (ESRH) has skill in discerning significantly tornadic events from those that are not.

This study explored the effects of incorporating 0-500 m ESRH into the VTP and issues relating to the parameter’s false alarm rate by examining RUC/RAP forecast soundings for 302 U.S. tornadic events (83 …

Backyard Grower-Consumer Perceptions Of Rabbit Meat Consumption In Rural Mississippi, Mildred Elizabeth Murphree

Theses and Dissertations

Every country in the world is affected by one or more forms of malnutrition. Malnutrition includes three conditions: undernutrition, micronutrient deficiencies or excesses, or overnutrition. Obesity is a greater contributor to death than undernutrition. Age, sex, ethnicity, socioeconomic status, and education level affect obesity. The rates of obesity vary considerably between states and regions of the country. The state of Mississippi is ranked as the poorest state in the nation and Mississippi has the highest adult obesity rate at 40.8% (Farberman & Kelley, 2020).

Rabbit meat production and consumption is a possible solution to malnutrition worldwide (Petrescu & Petrescu-Mag, 2018). …

Maternal Nutrient Restriction And Melatonin Supplementation Alter Neurotransmitter Pathways In Bovine Fetal And Placental Tissues, Allison R. Harman

Theses and Dissertations

Nutrient restriction is a relatively common production insult to pregnancy in cattle. Recently, melatonin supplementation has been investigated as a possible therapeutic to rescue the negative effects of nutrient restriction. Neurotransmitters have been implicated as having negative programming effects in mouse and human pregnancies, manifested as metabolic and neurologic disorders. The role of neurotransmitters in fetal development has only begun to be understood in mice and humans. Neurotransmitters have not been analyzed in cattle, much less within the context of a compromised pregnancy. Brangus heifers were allotted to one of four treatments (ADQ-CON, RES-CON, ADQ-MEL, RES-MEL) in either Fall 2019 …

Immobilization Of Uranium And Iodine By Calcium Phosphate Minerals, Angel L. Jimenez-Arroyo

Theses and Dissertations

This dissertation is comprised of three independent but interconnected studies with the scope of further understanding uranium and iodine partitioning between apatite and fluid. The studies herein presented investigated: 1) brushite to apatite crystallization method; 2) the degree of uranium incorporation into apatite; 3) the degree of iodine incorporation into apatite. The importance of this work is assessing the role of apatite in immobilizing these elements, where uranium is a major component of spent nuclear fuel and iodine is a chemical analog of its radioactive isotope (¹²⁹I).

What Is Distress Tolerance? A Mixed Methods Investigation Into Distress Tolerance And Its Measurement, Alisson Nicole Schultz Lass

Theses and Dissertations

Distress tolerance is often defined as one’s ability to tolerate and withstand negative and/or uncomfortable emotional states (Simons & Gaher, 2005; Zvolensky et al., 2001). However, after nearly two decades of research, there is still no consensus on how to best conceptualize and measure distress tolerance. A historical account of the conceptualization and measurement of distress tolerance demonstrates that the distress tolerance literature may have missed a crucial step in theory development: obtaining a thorough understanding of the concept in question (Dubin, 1969). Without adequately addressing this important step in theory development, it is likely that continued efforts to research …

Effects Of Mass Death On Community Structure And Ecosystem Function, Abby Kimpton Jones

Theses and Dissertations

Death and decomposition are natural processes that are generally well-understood. However, large events of death, such as mass mortality events (MMEs) are increasing in frequency and their impacts on the ecosystem are largely unknown. These events may have both bottom-up effects from increased nutrient input as well as top-down effects from loss of an ecological functional group by the affected population. Different functional MMEs may result in different top-down effects, creating cascading effects. In Chapter 1, I test the hypothesis that scavenger and herbivore simulated MMEs generate novel bottom-up and top-down effects. Results indicate that MMEs have a significant effect …

Soybean Potassium Utilization During Reproductive Growth Stages In Response To Potassium Timing, Potassium Rate, Herbicide Injury, And Desiccation, Tyler Lawrence Richmond

Theses and Dissertations

Potassium (K) deficiency of soybean [Glycine max (Merr.) L.] is common throughout the Mid-Southern region of the United States. Visual symptoms of K deficiency may be absent or subtle during early and mid-reproductive growth stages. Correcting K deficiency in-season is problematic due to limited research. Information regarding soybean yield response to in-season fertilizer K application time is limited to growth stages prior to the onset of R1. Research is also limited on new higher yielding soybean cultivars. The objective of this study was to evaluate influences of in-season K application timing during reproductive growth stages on soybean yield. Field experiments …

Barnyardgrass Control In Mississippi With Different Herbicides And Herbicide Mixtures, Hunter D. Bowman

Theses and Dissertations

With the adoption of the Xtend^® technology growers began to report reduced control levels of weedy grasses when applying tank-mixes of glyphosate and dicamba. Therefore, research was conducted at the Delta Research and Extension Center in Stoneville, MS from 2019 to 2021 to examine influence of herbicide mixtures with dicamba, as well as carrier volume and nozzle type. Results indicated barnyardgrass control 14 and 28 DAT was greatest with glyphosate alone. Control was not different when DGA or BAPMA dicamba or 2,4-D choline were mixed with glyphosate. At 28 DAT, barnyardgrass control was 15 to 18% lower with herbicide …

Let’S Talk: The Dual Process Model Of Supportive Communication In Peers, Erica Marie Szkody

Theses and Dissertations

Supportive messages occur within most relationships. Researchers have found strong relationships between social support and various physical and psychological health outcomes, but the specific mechanisms at work have yet to be fully explored. Many factors contribute to whether a supportive interaction is processed as helpful or supportive by the recipient including relational factors, message content, past experiences, etc. For peer dyads, the context and supportive messages individuals provide their peer may inhibit or contribute to their perception of their peer’s supportive behavior. The current study examined the impact of contextual factors (such as family communication patterns and relationship quality) on …
