Effects Of Increased Shoe Collar Height And Limb Dominance On Landing Knee Biomechanics In Collegiate Volleyball Players, Lindsey Legg

Master's Theses

Athletic footwear with higher collar heights are worn to restrict ankle motion. Reduced ankle dorsiflexion has been associated with increased frontal plane knee motion. Volleyball players wear mid-cut shoes (MC) that have an increased collar height rising slightly superior to the talocrural joint and malleoli. The purpose of this study was to determine the effect of MC and limb dominance on knee landing mechanics. It was hypothesized that participants would land with greater initial contact (IC) and peak frontal joint plane angles and moments and smaller IC and peak sagittal plane joint angles and moments at the knee in MC …

Determining The Refractive Index Of Phytoplankton Via Direct Measurement Of Cellular Structures, Michael Kamowski

Master's Theses

The refractive index of phytoplankton has never been directly measured before despite its importance towards studying the optical characteristics of marine particles. Previous attempts to measure it have been done through indirect methods. While these methods have proven useful, they contain assumptions about the particles morphology and composition that cause for uncertainty with the measurements. Through the use of the 3D Cell Explorer, a high precision holotomographic microscope, the RI of phytoplankton can be directly measured for the first time. With volume measurements, the phytoplankton were found to not display a single bulk RI, instead the bulk RI was different …

PPiase and RuBisCO with molecular weight 15 and 52 KDa were identified as the proteins after peptide mass …

Freckled Darter (Percina Lenticula) And Other Fishes’ Usage Of Wood Pile Habitat, Noah Daun

Master's Theses

Effectively sampling habitat with the proper techniques is essential for our understanding of the animals that use the habitat, both for individual species and entire species assemblages. Percina lenticula is a species of special concern in the state of Mississippi due to low numbers of historical records. This species is known to inhabit wood pile habitat in rivers, a habitat that has been under-sampled historically due to inefficiency with most commonly used gear. Seines are typically not effective at sampling wood piles, resulting in sampling bias underestimating the number of P. lenticula and potentially other species utilizing such habitats. This …

Driving Demands Of A Successful Protest: A Comparative Analysis Of Drivers That Leads To A Successful Outcome Of Protest, Prince Tetteh

Master's Theses

The 2020 Global Peace Index found that there has been a drastic increase of civil unrest incidents worldwide since 2011. According to the Index, there were 282% more riot cases and 821% more general strikes across the world, with Europe having the most riots, protests, and strikes. Extant literature suggests that protest is a web of interconnected demands that sends a weak signal to policymakers or the intended target. I examine some of the drivers of protest that are likely to impact the chances of protesters demands being met either in part or in full. I further analyze how each …

Caregiver Augmentative And Alternative Communication (Aac) Education And Training: A Survey Of Caregiver And Slp Perspectives, Michelle Hasenkampf

Master's Theses

Speech-language pathologists (SLPs) must address caregiver education and training throughout early intervention, including when implementing augmentative and alternative communication (AAC). Previous research has made recommendations describing practices for SLPs in this area, such as incorporating direct instruction and caregiver participation, as well as addressed how recommendations compare to implementation of these strategies in actual practice. Two parallel surveys were created to examine SLP and caregiver experiences and opinions of various topics and methods utilized in AAC caregiver education and training. 19 SLPs and 5 caregivers completed the surveys. SLPs notably exhibited differences in practice and opinions related to the methods …

Fourthspace: The Role Of Active Social Inclusion In The Workforce Entry Of Syrian Refugees In Scandinavia, Anisa Abeytia

Master's Theses

The 2015 displacement of Syrian refugees into Scandinavian countries provoked a refugee integration policy adjustment that focused on workforce and higher education entry. It is a policy approach that requires attention on barriers to workforce entry to ensure effective policy implementation. This article provides insight into the larger, often overlooked barriers of Eurocentrism and historical biases on refugee labor integration and provides policy solutions to reduce their impact. Active social inclusion (ASI) and Fourthspace are introduced as a framework to reduce biases to workforce entry and integration time barriers faced by Syrian refugees. ASI can provide mechanisms to increase access …

Predicting Suicide Risk Among Youths Using Machine Learning Methods, Saswati Bhattacharjee

Master's Theses

Suicide is the second leading cause of death among youths in the USA. Although machine learning approaches have provided great potential for predicting suicide risk using survey data, prediction accuracy may not meet the need for clinical diagnosis due to the intrinsic characteristics of datasets. In this study, I perform a comparative study of six classification algorithms including naïve Bayes (NB), logistic regression (LR), multilayer perceptron (MLP), AdaBoost (Ada), random forest (RF), and bagging using YRBSS dataset and investigate the effectiveness of several data handling techniques to improve the overall performance of suicide risk prediction.

The dataset consists of 76 …

The Armed Forces Of Ukraine: From The Collapse Of The Soviet Union To The Russian Invasion, Gunnar Bash

Master's Theses

The Armed Forces of Ukraine (Ukrainian: Збройні сили України (ЗСУ), Zbroyni Syly Ukrayiny, (ZSU)) were once internationally unknown, having fought no wars since the fall of the USSR in 1991. However, with the Russian invasion of Ukraine, the ZSU has become a topic of international debate and one that is discussed daily between major think tanks and war studies institutions, along with the world’s most powerful militaries. Looking back to 1991, I discuss how the ZSU came to be, how they dealt with Russian and partisan transgressions in Ukraine, and how they have evolved from their interactions with the West …

New Insights Into The Paleovegetation Of The Ancient Underwater Forest Located In The Northern Gulf Of Mexico, Karla Lizarraga Garcia

Master's Theses

A well-preserved remnant of an ancient bald cypress forest (hereafter, Underwater Forest) constitutes the only known archive of a glacial refuge on the once exposed continental shelf of the Northern Gulf of Mexico. This forest existed around 41-72 yBP (MIS 3-5) according to the existing dating methods applied on previous studies. As the climate conditions and sea levels changed, the vegetation of this glacial refuge shifted from bald cypress forests to open marshes, altering the vegetation dynamics. The present research analyzed four new cores (21DF-5A, 21DF-5B, 15DF-6, and 16DF-3A), which provided additional insights into the vegetation that once existed in …

An Investigation Of Resistance Training Behavior, Non-Specific Psychological Distress, And Perceived Barriers To Resistance Training In Self-Identifying Female Undergraduate Students, Jody Sobel

Master's Theses

The prevalence and severity of depression symptoms amongst college students, specifically female identifying undergraduate students, is worrisome. There is a great deal of research that suggests a relationship between exercise, specifically resistance training (RT), and mental health. That said, current literature suggests that many female identifying students are not engaging due to perceived barriers. This, perhaps because of the plethora of barriers one can perceive. The purpose of this study was multifold 1) to examine the prevalence and severity of non-specific psychological distress; 2) to determine if there were differences between Kessler 6 Non-Specific Psychological Distress Scale (K6) categories (i.e., …

Implementation Of Methods For Cell Therapy Research And Assessment Of The Impact Of Cryopreservation, Samantha Lynes

Master's Theses

Cell therapy is the administration of living cells into a patient to prevent or treat a variety of diseases and illnesses. The cell therapy industry is rapidly expanding, and continued research is necessary for manufacturing safe and effective therapies. Although cell therapy manufacturing generally involves cryopreservation processes for storage, there are limited standards for cryopreservation processes and assays required to evaluate cell therapies post-thaw, and limited understanding exists about how a recovery period post-thaw could impact cell health. The overall goal of this thesis was to evaluate the effect of cryopreservation and potential subsequent recovery time on cell viability.

A Proof Of Concept For Detection Of Palato-Lingual Contact Without Intraoral Electrodes In A Human Participant, Amitava Biswas

Master's Theses

The author of this thesis conceived and investigated an unexpected electrical signal that may not be noticed during regular electroglottography (EGG) when electrodes are conventionally placed on the anterior surface of the throat. It appears that there is a measurable electrical signal from the EGG equipment when electrodes are placed over the frontal cheek (belly of zygomatic muscle), and the tongue is elevated to contact the hard palate, or the tongue is lowered to break the contact. Therefore, this phenomenon is designated as unconventional electroglottography (UEGG, Dr. Steven Cloud, private communication, July 17, 2022).

Two distinctive patterns of waveforms were …

I’Ll Be Goldenrod And You’Ll Be Aster: The Case For Revolutionizing Western Methods Of Teaching Using Indigenous Ontologies, Joanna Logerfo

Master's Theses

An interesting facet of living as a human in the 21st century is contending with the end of the world. It’s been imagined in a thousand ways over the past twenty years. Will it be zombies? Aliens? An AI revolution? Or will it perhaps be something more mundane, more “down-to-Earth”? The floods, the droughts, the famines, and all the rest of the cataclysmic global events that occur every year have taken center stage in the world-ending debate, parading under a name as threatening and expansive as the Boogeyman: climate change. A recent article from NPR covered the United Nations’ 2022 …

Nutrition-Related Factors Impacting The Bone Health Of Female Sports And Performance Collegiate Athletes, Elizabeth Doll

Master's Theses

Low bone mineral density is commonly found in female athletes and has been related to the energy adequacy and nutrient density of the athlete’s diet. Insufficient dietary energy intake and/or excessive energy expenditure can lead to low energy availability in female athletes, which has been shown to disrupt endocrine, metabolic, and physiological functions. Psychological distress in competitive athletes may affect dietary choices and patterns. To meet their personal or performance standards/goals, an athlete may go to extremes to achieve those standards/goals, including altering their dietary intake.

This study aimed to evaluate the nutrition-related factors affecting the bone health of collegiate …

A Model Knight: Sir Gawain, Chivalric Contradictions, And Grief In Medieval Literature, Kennis Jobe

Master's Theses

Scholarship on medieval and Arthurian chivalry in recent decades has focused largely on the Gawain Poet’s 1375 Sir Gawain and the Green Knight and Sir Thomas Malory’s 1470 Le Morte D’Arthur. These two romances seem to offer more critical looks at the chivalric system than the glorification of knightly life provided by romances from the previous centuries of the high medieval period. In past works such as L’atre Périlleux and Claris et Laris, Sir Gawain is depicted as the ideal knight—in these poems he is humble, strong, noble, and always perfectly in accord with the chivalric code. In Sir Gawain …

An Evaluation Of The Effect Of Degradation On Irisplex Snps, Maria Gruber

Master's Theses

The information from short tandem repeats (STRs), the current standard forensic DNA typing technology, does not always result in identification. In these cases, there are other informative markers in DNA that can be used to help generate investigative leads, one of which is single nucleotide polymorphisms (SNPs). One of the uses of SNPs is for phenotype determination. Among the phenotypic characteristics that can be predicted is eye color. A commonly used tool for eye color prediction is the free, online statistical prediction model IrisPlex, which includes 6 SNPs known to control eye color.

While SNPs can be useful, they, like …

Pollinator Diversity On A Shortleaf Pine-Oak-Hickory Restoration Site, Taygan Kohlman

Master's Theses

Land use and cover are increasingly changing due to climate change and anthropogenic activities with many of these changes negatively impacting biodiversity. However, ecosystem restoration may help reverse these patterns. Northern Louisiana was historically dominated by shortleaf pine-oak-hickory forests but has been converted largely to loblolly pine forests with little-to-no herbaceous ground cover. The objective of this study is to determine how different practices on a shortleaf pine-oak-hickory forest restoration site affect pollinator diversity. I sampled pollinators from locations within areas under three different management regimes: 1) prescribed burning with active herbicide treatments for non-desirable plant species, 2) burning only, …

The Impact Of Leaf Litter Diversity On The Colonization Of Aquatic Insects, Daniel Edwards

Master's Theses

Ephemeral pools provide habitat to a wide diversity of aquatic insects which colonize pools to establish new populations in higher quality habitats. These pools rely on nutrient inputs from the surrounding terrestrial landscape, predominantly through leaf litter. Using mesocosms, we tested for the effect of leaf litter diversity (richness and functional diversity) on the colonization of aquatic insects. Leaf litter influences characteristics of a pool (tannins, water color, and nutrients) which may make them more or less desirable to potential colonizers. I added unique mixtures of leaf litter with different numbers of species (0, 3, 5, 7, and 9) and …

Lunar Applications Of Direct Contact Membrane Distillation For Regolith And Hydroponic Water Processing, Mark Wong

Master's Theses

Water management has always been a critical issue facing lunar missions, since its uses are as numerous as they are vital. Using ionic liquids has been proposed for the purpose of processing the metal oxides in lunar regolith into oxygen and metals. The process used dilutes the ionic liquid. Recycling the ionic liquid solution after regolith processing is essential to reduce materials required in resupply missions and to supply oxygen. Water will also be needed for lunar farms to both grow food and assist in maintaining a habitable atmosphere. The use of direct contact membrane distillation (DCMD) technology is a …

Deadwood Facilitates Increased Predators Resulting In Distinct And Functionally Different Leaf Litter Communities, Nicholas Benedetto

Master's Theses

Community structure and ecosystem function may be driven by the amount and size of habitat or energy within an environment, but these metrics (space and energy) are difficult to separate, especially in systems where habitat is also a source of energy such as detritus (dead organic matter including deadwood). Deadwood can impact forest food webs through the creation of habitat and provision of resources and initial differences in wood characteristics may differentially impact food webs. Bark beetles attack and kill pine trees, inoculating them with bluestain fungi (Ascomycota: Ophiostomataceae). Bluestain fungi may increase termite presence in deadwood, and possibly in …

Trace Dna Detection Using Diamond Dye: A Recovery Technique To Yield More Dna, Leah Davis

Master's Theses

This study aspires to find a new screening approach to trace DNA recovery techniques to yield a higher quantity of trace DNA from larger items of evidence. It takes the path of visualizing trace DNA on items of evidence with potential DNA so analysts can swab a more localized area rather than attempting to recover trace DNA through the general swabbing technique currently used for trace DNA recovery. The first and second parts consisted of observing trace DNA interaction with Diamond Dye on porous and non-porous surfaces.

The third part involved applying the Diamond Dye solution by spraying it onto …

An Adaptive Digital Predistortion Process Consisting Of An Fir Filter And Lms Algorithm For Use In Rf Power Amplifier Linearization, Alexander R. Vita

Master's Theses

Radio Frequency (RF) Power Amplifiers (PA) are fundamentally non-linear due to their design and environmental effects, this non-linearity reduces performance and introduces distortion to the system. To improve the linear region of operation an adaptive Digital Predistortion Process (DPD) is used consisting of an adaptive Finite Impulse Response (FIR) filter utilizing the Least Means Square (LMS) algorithm. Unlike other DPD processes this one is adaptive in nature and requires no calibration allowing the digital pre-distorter to keep up with the dynamic changes in the PA non-linearity. The performance of this process is evaluated on the ability to increase the linearity …
