Hunter-Gatherer Behavior At Dorn Levee #1 (38fa608): An Analysis Of Lithic Assemblage Formation At A South Carolina Piedmont Site, Robert Altom Cesarini Lyerly

Theses and Dissertations

The site of Dorn Levee #1 (38FA608) in the South Carolina Piedmont has the potential to provide unique information regarding the behaviors and activities of the hunter-gatherer populations who inhabited it throughout prehistory. The Late and Terminal Archaic Period landscape in the Southeast saw with it many major changes in hunter-gatherer lifeways that had begun initial development in periods prior. The continued use of Dorn Levee #1 suggests that it was highly important for these hunter-gatherers, and an analysis of their mobility patterns and general behaviors through the associated lithic debitage material can assist in illuminating its role within a …

Hydrogenation Of Dimethyl Oxalate To Ethylene Glycol Over Silica Supported Copper Catalysts, Xinbin Yu

Theses and Dissertations

Ethylene glycol is a bulk chemical and hydrogenation of dimethyl oxalate (DMO) on Cu/SiO2 catalysts is the final reaction step in a growing industrial syngas to ethylene glycol (StEG) process. Efforts to improve the performance of the catalysts are still ongoing and the detailed catalytic mechanism remains controversial.

In the present work, a series of 10 wt% Cu/SiO₂ is prepared.by urea hydrolysis method and indium species is introduced by incipient wetness impregnation. Reaction studies show that 0.25 wt%-0.5 wt% of indium species can dramatically enhance the performance of 10 wt% Cu/SiO₂ catalyst. Various characterizations reveal that indium species …

African American Teachers’ Perspectives On Principals’ Leadership Styles And The Influence On Teacher Morale, Ernestine Young

Theses and Dissertations

Morale is a concept that denotes how workers feel about their work and the environment in which they work (Robbins, 2003). Low teacher morale is not a new problem; however, with increasing frequency of low morale, teachers are affected all over the nation because of the financial and academic toll it has on education. Low morale typically impedes the achievement of the organization’s desired outcome and corresponds with unresolved grievances, attrition, and high absenteeism. Low morale is associated with billions of dollars spent per year. Low morale is due to effects such as stress, teacher burnout, absenteeism, attrition, and small …

Throughout the document, the author will explore the relationship between the three musicians through the analysis of Das Lied and a detailed exploration of interpretations of …

Examination Of Daily Steps In People With Parkinson’S Disease & Stroke: Two Steps Forward, Reed Handlery

Theses and Dissertations

Despite the well-known health benefits associated with physical activity (PA), the majority of people with Parkinson’s disease (pwPD) and people with stroke do not meet national PA guidelines. As a result, these two groups of people are at increased risk for development of cardiovascular disease, additional disability and death.

Walking as a mode of PA has been shown to improve the health of both pwPD and people with stroke. In fact, a step count of >6000 steps per day is related to a decreased risk of subsequent cardiovascular events in people with stroke. Daily walking is also strongly recommended by …

Application Of The “Idisco” Full-Brain Tissue Clearing Method: A View Of Dopamine And Inflammation In The Hiv-1 Transgenic Rat, Kristin Nickole Kirchner

Theses and Dissertations

The iDISCO (immunolabeling-enabled three-dimensional imaging of solvent-cleared organs) method is a quick, inexpensive, and easily adaptable tissue staining and clearing procedure that allows neuroscientists to study a protein of interest in a whole, unaltered tissue sample. While the iDISCO method was initially tested and validated for mice embryos and brains, the current experiment sought to adapt the method for use in the rat using HIV-1 transgenic (Tg) rat brain tissue. Antibodies for tyrosine hydroxylase and Iba-1 were validated in the HIV-1 Tg rat and in F344/N control rats using iDISCO. Confocal images were taken of tyrosine hydroxylase positive neurons in …

Evaluating The Stabilization Of Gypseous And Gypsiferous Sands Using Different Chemical Additives To Mitigate Gypsum Dissolution, Mohammed Kamil Faris

Theses and Dissertations

Gypsum, which is dihydrate calcium sulfate, (CaSO4.2H2O), is widely available in different sizes, from the size of a rock to the size of a few micrometers as a mineral, in different types of soils. It is primarily found mainly in arid and semi-arid areas around the world at different depths. Soils with gypsum and even gypsum rocks are very hard in their dry state. However, these soils and rock will experience remarkable dissolution upon wetting.

The dissolution phenomenon, which takes place in soils that contain gypsum, creates different geotechnical problems within the soil’s profile, along with foundation issues for structures …

Local Eigenvalue Modification Procedure For Real-Time Model Updating Of Structures Experiencing High-Rate Dynamic Events, Claire Rae Drnek

Theses and Dissertations

Estimating the state of structures that experience high-rate dynamics requires real-time model updating capabilities. In this work, high-rate dynamic events are characterized by 1) large uncertainties in the external loads, 2) high levels of non-stationarities and heavy disturbances, and 3) unmodeled dynamics generated from changes in system configurations. To achieve real-time model updating, an algorithm must circumvent any pre-calculations and be able to update the structure’s state on the timescale of 2 ms or less. This can be accomplished in one of two ways: either by creating a simplified model of a complex structure or by simplifying the calculations needed …

Talkin’ Black And Sounding Gay: An Examination Of The Construction Of A Multiplex Identity Via Intraspeaker Variation, Brianna R. Cornelius

Theses and Dissertations

Gay African-American men hold membership in at least three groups – Gay, Black, and Male – that are grounded in ideologies and which provide linguistic resources that are complex and potentially conflicting. As such, these men exist at the cross-section of socio-cultural groups whose perspectives and presentations are often framed in opposition to one another. This dissertation seeks to explore the ways in which such complex identities are created through the use of language. Specifically, this project will investigate how a Gay Black man (GBM) constructs his complex identity over the course of several interviews/conversations in which topic and interlocutor …

Artificial Intelligence Approaches For Structural Health Monitoring Of Aerospace Structures, Kimberly A. Cardillo

Theses and Dissertations

Structural health monitoring (SHM) and non-destructive evaluation (NDE) have been a significant research topic to help with damage detection in aerospace structures. SHM and NDE techniques are based on extracting damage sensitive features to determine the criticality of damage and lifetime of a structure. Acoustic emission (AE) signal detection is an important technique in SHM and NDE especially for fatigue crack growth. AE signals for thin aerospace structures consist of ultrasonic guided Lamb waves that propagate through the structure. This thesis focuses on AE signal repeatability, load at which AE signals occur, feature extraction, artificial intelligence and electro-mechanical impedance of …

Comprehensive School Reentry After A Disciplinary Alternative School Placement: A Phenomenological Study Of Secondary School Counselors’ Perceptions And Experiences, Chanta Pressley Moore

Theses and Dissertations

The American School Counselor Association calls upon school counselors to address the needs of all students; this includes students once served in DAEPs. However, the experiences and perspectives of school counselors working with students re-entering school after a mandatory DAEP placement is not widely understood. Employing a qualitative design, this phenomenological study aims to gain an in-depth understanding of perceptions and experiences of school counselors that serve students transitioning and re-entering back into comprehensive school after a DAEP placement.

Sex-Based Differences In Concussion Outcomes Among Adolescents And Young Adults, Jacob James Michael Kay

Theses and Dissertations

Concussive injuries among youth are a serious public health concern in the United States, with increasing incidence leading the Centers for Disease Control and Prevention to classify these injuries a “silent epidemic.” Though most concussions in youth resolve within a few weeks, a significant proportion (~15-20%) of individuals will experience persisting symptoms that can negatively affect important aspects of social life, as well as academic and vocational performance. Furthermore, guidelines from the most recent Consensus Statement on Concussion in Sport highlight the importance of considering individual characteristics that may modify the nature and outcomes of concussion. Biological sex is one …

Categorical And Fuzzy Ensemble-Based Algorithms For Cluster Analysis, Bridget Nicole Manning

Theses and Dissertations

This dissertation focuses on improving multivariate methods of cluster analysis. In Chapter 3 we discuss methods relevant to the categorical clustering of tertiary data while Chapter 4 considers the clustering of quantitative data using ensemble algorithms. Lastly, in Chapter 5, future research plans are discussed to investigate the clustering of spatial binary data.

Cluster analysis is an unsupervised methodology whose results may be influenced by the types of variables recorded on observations. When dealing with the clustering of categorical data, solutions produced may not accurately reflect the structure of the process that generated them. Increased variability within the latent structure …

Distinguishing Neuro-Markers Of Math Learning Disability Using Eeg Coherence, Jessica C. Luedke

Theses and Dissertations

Math learning disability (MLD) is a neurodevelopmental disorder that results from specific cognitive deficits involved with numeric computation and arithmetic that cannot be attributed to low general ability. Although MLD has a significant impact on life outcomes, only a few studies have evaluated unique neurological profile differences between those with and without specific math deficits. EEG coherence has been useful for evaluating neural disconnections in children with neurodevelopmental disorders but has never been used to explain cognitive deficits found in children with MLD. The current study contributed to the literature by evaluating at-rest electrocortical signatures in those with MLD ( …

Fermi-Unsmearing In Single Charged Pion Electroproduction Cross-Section Measurements For The Neutron And Proton In Deuterium, Gary Hollis

Theses and Dissertations

Electron scattering cross-sections for two different reaction channels, e- + p→ e- + n + ϖ + and e- + n → e- + p ϖ - using an unpolarized deuterium target, were extracted from Jefferson Lab experiment E1E data with a beam energy of 2.039 GeV, providing a (W;Q2) coverage of 1.1 GeV < W < 1.9 GeV and0.4 GeV2< Q2 2. Although there has already been an analysis of this same data set for the second reaction channel listed above [1], more of the cross-section domain has been covered in this analysis due to applying a new technique called Fermi-unsmearing. Fermi-smearing is a distortion in a cross-section measurement which occurs whenever the target is erroneously assumed to be at rest but is in fact a bound nucleon as part of a larger nucleus (and thus is in Fermi-motion). Fermi-unsmearing is a Monte Carlo method presented in this work for generating a correction factor that removes the Fermi-smearing effect from an existing cross-section measurement that suffers from Fermi-smearing. Using Fermi-unsmearing can have the advantage of significantly larger statistical sample sizes given the same data set due to allowing less strict final data selection criteria, as occurs in a Fermi-unsmeared analysis of the e- + n→ e- + p + ϖ- channel in contrast to a fully-exclusive analysis of the same channel. The same Fermi-unsmearing method is applied to the first channel after having established the efficacy of the method using the second channel.

Engaging Youth And Families Within The Context Of Evidence-Based Treatment (Ebt) Implementation: Examining Integrity Of Engagement Practices To Different Ebt Information Sources, Eleanor Wu

Theses and Dissertations

Promoting and maintaining client engagement has proven to be a significant challenge across community mental health settings, including within the context of implementing evidence-based treatments (EBTs) (De Haan et al., 2013). Few efforts have been made to equip providers with empirically-sourced engagement strategies outside of the limited set of engagement procedures covered in EBT protocols. To inform efforts for improving EBT accessibility, the current study characterizes the delivery of engagement practices from the literature within the context of EBT implementation, and examines provider integrity of engagement practice use according to two information sources (i.e., the provider’s EBT training history and …

Factors That Influence Screening, Brief Intervention, And Referral To Treatment (Sbirt) Implementation In Non-Medical Settings, Andrew Joseph Flaherty

Theses and Dissertations

Screening, Brief Intervention, and Referral to Treatment (SBIRT) is an evidenced-based intervention model designed to reduce substance use. While initially used in a variety of medical settings, SBIRT is increasingly implemented in non-medical settings. Unfortunately, very little is known about SBIRT implementation in non-medical settings. Therefore, the purpose of this exploratory qualitative study is to understand if professionals recently trained in SBIRT are using it and factors that influence implementation of SBIRT from their perspective.

In-depth qualitative interviews were conducted using a purposive sampling frame, comprised of practitioners recently trained in SBIRT. Interviews were recorded, and then transcribed verbatim, transcripts …

Targeted Engagement Of The Action Selection Network During Task-Oriented Arm Training After Stroke, Jill Campbell Stewart Pt,Phd, Kaci Handlery, Jessica F. Baird, Erika L. Blanck, Geetanjali Pathak, Stacy L. Fritz

Faculty Publications

Action selection (AS), or selection of an action from a set of alternatives, is an important movement preparation process that engages a frontal-parietal network. The addition of AS demands to arm training after stroke could be used to engage this motor planning process and the neural network that supports it. The purpose of this case series is to describe the feasibility and outcomes associated with task-oriented arm training aimed at engaging the AS behavioral process and the related neural network in three individuals with chronic stroke. Three participants with mild to moderate motor deficits completed 13 to 15 sessions of …

Top Hadrons In Lorentz-Violating Field Theory, Brett David Altschul

Faculty Publications

If there is Lorentz symmetry violation in the t quark sector of the standard model, changes to particles’ dispersion relations might allow for the existence of stable top-flavored hadrons. Observations of the survival of high-energy γ-rays over astrophysical distances can be used to place constraints on Lorentz violation coefficients in the t sector at ∼10⁻⁴–10⁻⁶ levels of precision.

The Impact Of Service Firm’S Environmentally Friendly Reputation In The Context Of Revenue Management, Choongbeom Choi, Miyoung Jeong Ph.D.

Faculty Publications

In revenue management practice, customers’ perceived fairness is a critical issue. Prior research examined the effect of revenue management on customers’ perceptions of fairness by implementing two different conditions: fencing and framing. In this study, the authors evaluated the role of a service firm’s environmentally friendly reputation under the conditions of fencing and framing. Results indicated that an environmentally friendly reputation only moderated the effect of framing on perceived fairness. In particular, when the firm had a poor reputation, framing as a discount rather than framing as a surcharge increased customers’ fairness perceptions. When the firm had a good reputation, …
