Do Individual Responses To Resistance Exercise Exist To An Extent That Can Be Detected Beyond That Of Measurement Error/Random Biological Variability?, Scott J. Dankel
Do Individual Responses To Resistance Exercise Exist To An Extent That Can Be Detected Beyond That Of Measurement Error/Random Biological Variability?, Scott J. Dankel
Electronic Theses and Dissertations
Millions of dollars are spent analyzing inter-individual differences in response to resistance exercise, but the lack of a non-exercise control group means they may simply be examining random error. The purpose of this study was to determine whether there are inter-individual differences in response to two distinct resistance exercise protocols. Participants (n=151) were randomly assigned to one of 3 groups as follows: (1) a traditional exercise group performing 4 sets to failure with a load that could be lifted 8-12 times; (2) a one-repetition maximum (1RM) training group performing a 1RM test each visit; and (3) a non-exercise control group. …

Progress Toward The Synthesis Of 3-Methoxyflavones As Potential Antioxidants, Neuroprotective Agents, And Trifluoromethylated 19f Nmr Probes, Reem Alkhodier
Electronic Theses and Dissertations
The total synthesis of polyhydroxylated flavones have proven to be challenging, due to the presence of more than one hydroxyl group. Direct cyclization was not successful in any of the attempts. However, by using a silyl protecting group, the cyclization was feasible. Other reactions like the Friedel-Crafts acylation and selective protection of phenols were also difficult.
Courtroom Wars: Constitutional Battles Over Conscription In The Civil War North, Nicholas Matthew Mosvick
Courtroom Wars: Constitutional Battles Over Conscription In The Civil War North, Nicholas Matthew Mosvick
Electronic Theses and Dissertations
In February 1863, Congress considered a bill to create for the first-time conscription at the national level. Democratic politicians vigorously protested that the proposed act was unconstitutional and destroyed the state militias. When Congress passed the Enrollment Act, commonly known as the “Conscription Act,” on March 3, 1863, outcry from Democrats about the unconstitutionality of national conscription immediately followed. In New York and Pennsylvania, Democratic newspaper editors and politicians decreed the act the worst among the Lincoln war measures in threatening to subvert the constitutional republic and to transform the United States into a despotism under the control of an …
Hitting The Bullseye: The Influence Of Technical Debt On The Accuracy Of Effort Estimation In Agile Projects, James Ball
Hitting The Bullseye: The Influence Of Technical Debt On The Accuracy Of Effort Estimation In Agile Projects, James Ball
Electronic Theses and Dissertations
As firms rapidly develop solutions in order to increase revenue and market share, software development decisions considered to be temporary shortcuts and/or compromises may be implemented. These shortcuts represent “technical debt,” a metaphor which succinctly describes a software solution that should be “paid in full” or remediated in the future. Software architects and developers intend to resolve the “debt” in future product releases, but practitioners recognize that the challenge of always innovating may indefinitely postpone this remediation effort. Further, the accumulation of technical debt may have long term impact on the product’s maintainability by the software development teams and, consequently, …
Bridge To Student Success?: An Evaluation Of The Effectiveness Of The University Of Mississippi's Jumpstart Summer Bridge Program, Emily Ferris
Electronic Theses and Dissertations
Summer bridge programs (SBPs) are a popular programmatic intervention of colleges and universities to assist students with the transition from high school to college and provide students with the academic and social tools they need to be successful. Despite their popularity, a survey of relevant literature indicated that bridge programs are not routinely evaluated to measure their effectiveness. This study sought to contribute to the body of existing literature by evaluating the effectiveness of the University of Mississippi’s (UM) JumpStart Summer Bridge Program and its impact on student success outcomes, including GPA, institutional retention, and degree completion, to establish concrete …
Synthesis Of Fluoroflavones As Potential Neuroprotective Agents, Maali Alshammari
Synthesis Of Fluoroflavones As Potential Neuroprotective Agents, Maali Alshammari
Electronic Theses and Dissertations
Flavones are polyphenol natural products that are known to have neuroprotective effects against many diseases caused by the formation of reactive species. Flavonoids are subgroup of flavones and they are believed to function as antioxidants. Specifically, they target free radicals and eliminate its harmful effect on the cell. Fluoroflavones were designed to improve the potency of the antioxidant activity and potentially be used as neuroprotective agents. A monofluorinated and trifluoromethylated flavone were synthesized by using commercially available fluorination reagents, N-fluorobenzenesulfonimide; and Togni’s or Umemoto's respectively. After the synthesis of the desired flavones and their monofluorinated and trifluoromethylated derivatives, biological testing …
Gravitational Radiation From Superradiant Instabilities Of Rotating Black Holes, Shrobana Ghosh
Gravitational Radiation From Superradiant Instabilities Of Rotating Black Holes, Shrobana Ghosh
Electronic Theses and Dissertations
We use the Teukolsky formalism to calculate the gravitational radiation from a non-axi\-symmetric cloud formed due to superradiant amplification of a spin-0 bosonic field. We focus on the prospects of the future space-based gravitational wave detector, Laser Interferometer Space Antenna (LISA), and the current version of ground-based detector, Advanced Laser Interferometer Gravitational-Wave Observatory (AdLIGO), to detect or constrain scalars with mass in the range $m_s\in [10^{-19},10^{-15}]$ eV and $m_s\in[10^{-14},10^{-11}]$ eV, respectively. Using astrophysical models of black hole populations calibrated to observations we find that, in optimistic scenarios, AdLIGO could detect up to $10^4$ resolvable events in a four-year search if …
Performance Evaluation Of Blocking And Non-Blocking Concurrent Queues On Gpus, Hossein Pourmeidani
Performance Evaluation Of Blocking And Non-Blocking Concurrent Queues On Gpus, Hossein Pourmeidani
Electronic Theses and Dissertations
The efficiency of concurrent data structures is crucial to the performance of multi-threaded programs in shared-memory systems. The arbitrary execution of concurrent threads, however, can result in an incorrect behavior of these data structures. Graphics Processing Units (GPUs) have appeared as a powerful platform for high-performance computing. As regular data-parallel computations are straightforward to implement on traditional CPU architectures, it is challenging to implement them in a SIMD environment in the presence of thousands of active threads on GPU architectures. In this thesis, we implement a concurrent queue data structure and evaluate its performance on GPUs to understand how it …
Design Of Thermosensitive Hydrogel For Extended-Release Of Praziquantel, Sheng Feng
Design Of Thermosensitive Hydrogel For Extended-Release Of Praziquantel, Sheng Feng
Electronic Theses and Dissertations
Parasitic diseases are a severe threat to people and animals. Praziquantel is the most comanti-parasitic drug with high efficiency, and it has been used to treat parasitic diseases for many years. However, it has very strong gastrointestinal and liver metabolism that leads to a strong first-pass effect and a short half-life. Additionally, the frequent oral administration was inconvenient for the large livestock. To overcome these drawbacks, this study aimed to develop an extended-release thermosensitive hydrogel formulation that was applicable to the injectable administration. The praziquantel-loaded hydrogel formulation based on poloxamer 407 (20%, w/v) was prepared, and two strategies for modifications …

Community Resilience: A Meta-Study Of International Development Rhetoric In Emerging Economies, Rachel Ann Haggard
Community Resilience: A Meta-Study Of International Development Rhetoric In Emerging Economies, Rachel Ann Haggard
Electronic Theses and Dissertations
Understood generally, community resilience is the ability of communities to adapt, absorb, mitigate, and recover from shocks and stressors in such a way that facilitates positive future outcomes and reduces overall vulnerability to future shocks and stressors (Adger, 2000; Norris, Stevens, Pfefferbaum, Wyche & Pfefferbaum, 2008; USAID, 2013; Walker et al., 2004). The core of this definition relates to sustainability and the capability of socio-ecological systems and communities to adapt and transform to both day to day fluctuations and stressors as well as major disasters (Milman & Short, 2008; Walker et al., 2004). This meta-study seeks to shed light on …

Cross-Docking: A Proven Ltl Technique To Help Suppliers Minimize Products' Unit Costs Delivered To The Final Customers, Vahid Ghomi
Electronic Theses and Dissertations
This study aims at proposing a decision-support tool to reduce the total supply chain costs (TSCC) consisting of two separate and independent objective functions including total transportation costs (TTC) and total cross-docking operating cost (TCDC). The full-truckload (FT) transportation mode is assumed to handle supplier→customer product transportation; otherwise, a cross-docking terminal as an intermediate transshipment node is hired to handle the less-than-truckload (LTL) product transportation between the suppliers and customers. TTC model helps minimize the total transportation costs by maximization of the number of FT transportation and reduction of the total number of LTL. TCDC model tries to minimize total …
An Experimental Test Of Controls On Resource Exchange In An Ectomycorrhizal Mutualism, Amber Lynn Horning
An Experimental Test Of Controls On Resource Exchange In An Ectomycorrhizal Mutualism, Amber Lynn Horning
Electronic Theses and Dissertations
Models of resource exchange mutualisms utilize economic principles to explain how the costs and benefits of these interactions vary with environmental context. All of these models use a ratio of resource exchange (e.g., nitrogen: carbon) as the central variable, and it is unclear whether such exchange ratios predict outcomes of mutualisms in natural systems. Corrêa et al. (2008) hypothesized instead that the absolute flux of the most limiting nutrient, rather than the ratio of the two exchanged resources, best explains the benefits of resource exchange mutualisms. To distinguish between these two competing hypotheses, we measured resource transfers, and their ratios, …

To test these theories, I conduct a series of empirical tests using survey data from the American National Election Survey (ANES) and an original survey experiment. Chapter two examines how people’s ideological perceptions are moderated by living in a particular area. Using the ANES data, I conduct a regression analysis with an interaction of the respondent’s ideology and the geographic location. Chapter three analyzes how individuals perceive a political candidate based on partisan and geographic information presented to the respondent. Using an original survey experiment, this study seeks to illustrate how individuals across urban and rural America perceive Republican and …
The Effect Of Auditors’ Informal Communication In The Audit Environment On Financial Reporting Outcomes, Emily K. Hornok
The Effect Of Auditors’ Informal Communication In The Audit Environment On Financial Reporting Outcomes, Emily K. Hornok
Electronic Theses and Dissertations
I examine the effect of auditors’ recurring, informal communication with managers and other auditors on financial reporting outcomes in a laboratory experiment in which participants in the roles of auditors and managers interact in a stylized audit setting. My 2×2 between-subjects design manipulates whether the auditors are able to informally communicate with either, neither, or both the manager and other auditors. I find that when the auditor and manager informally communicate, they each develop a social bond, which increases the manager’s feeling of accountability towards the auditor, causes the manager to make more honest representations to the auditor, and leads …
Not All Scholars, But Gentlemen: The Making Of Virginian Manhood At St. Christopher's School, 1911-1969, Katelyn Frazer
Not All Scholars, But Gentlemen: The Making Of Virginian Manhood At St. Christopher's School, 1911-1969, Katelyn Frazer
Electronic Theses and Dissertations
Through close study of St. Christopher’s School—an all-boys’ school in Richmond, Virginia—during its first fifty years, this thesis historicizes upper-class white masculinity in Virginia during the first half of the twentieth century. The school’s founder, Churchill Gibson Chamberlayne, linked the Lost Cause myth with other movements in education at the time, especially Muscular Christianity and the country day school movement. By looking at how students and administrators at St. Christopher’s made and remade traditions surrounding notions of masculinity, in addition to more muted manifestations of gender at the school, illuminate the existence of a gender hierarchy even before gender integration. …

Pharmacokinetic Study Of Novel Anthraquinone Analogues, Yuhan Guo
Electronic Theses and Dissertations
Small molecules functioning as negative regulators of MDM2 have been considered as promising anti-cancer agents. A series of novel anthraquinone (AQ) analogues upregulate p53, a well-known tumor suppressor, by inactivating its antagonist protein MDM2. The novel AQ compounds synthesized through the modifications on the rhein scaffold were reported to have successfully arrested tumor growth. To have a better understanding of their underlying metabolism in vivo, pharmacokinetic (PK) studies were performed for the AQ compounds. A selective, accurate and reproducible assay methodology for PK study was set up for each AQ compound. The stabilities of AQ compounds were then evaluated …

Electronic Theses and Dissertations
The movement of coarse gravel in rivers in streams is important for many applications including wildlife habitation, river morphology, infrastructure maintenance and marine navigation. Physical sampling remains the most accurate method of determining coarse bedload transport but it can be expensive, dangerous and flow intrusive. Surrogate methods of monitoring bedload transport is an active area of research worldwide. One such method is the use of passive acoustics to record the sound generated when gravel particles in motion impact each other or the particles on the bed. This dissertation presents research and development that has been conducted on three key areas …

Of Mules And Mamas: Four Women, Africana Mothering, And Resistance, Ebony Olivia Lumumba
Of Mules And Mamas: Four Women, Africana Mothering, And Resistance, Ebony Olivia Lumumba
Electronic Theses and Dissertations
The black woman’s humanity is unjustly linked to domestic responsibility and, thus, the traditional constraints of mothering. The roles of the mother and the created archetype of the mammy often become marred with the latter role overtaking the former—leaving black children without full benefit and access to their biological maternal parent. With the pervasive threat to black lives present in spaces all over the globe, for women of the African Diaspora, simply deciding to accept the role of a mother to a life that is physically, socially, and economically under siege is revolutionary. Considering this, the act of mothering, especially …

Expression Of Tumor Necrosis Factor-Alpha In A Chick Model Of Stress Vulnerable, Treatment – Resistant Depression, Mary Katherine Jourdan
Electronic Theses and Dissertations
An increasing body of literature suggests a Major Depressive Disorder subpopulation, Treatment Resistant Depression (TRD), is associated with an increased immune response. More than a decade of research has identified and begun to validate a novel animal model of TRD. This study sought to determine whether TNF-α levels would be altered due to isolation stress and differentiated between stress-vulnerable and -resilient strains. Black Australorp and Production Red chicks were placed into isolation for varying times during which Distress Vocalization (dVoc) rates were calculated and transformed into entry into behavioral despair percent thresholds. Blood levels of TNF- α were quantified via …
Fabrication And Characterization Of Nonlinear Optical Ceramics For Random Quasi-Phase-Matching, Xuan Chen
Fabrication And Characterization Of Nonlinear Optical Ceramics For Random Quasi-Phase-Matching, Xuan Chen
Electronic Theses and Dissertations
A number of technologies rely on the conversion of short laser pulses from one spectral domain to another. Efficient frequency conversion is currently obtained in ordered nonlinear optical materials and requires a periodic spatial modulation of their nonlinear coefficient which results in a narrow bandwidth. One can trade off efficiency for more spectral bandwidth by relaxing the strict phase-matching conditions and achieve nonlinear interaction in carefully engineered disordered crystalline aggregates, in a so-called random quasi-phase-matching (rQPM) process. In this dissertation, we examine appropriate fabrication pathways for (1-x)Pb(Mg1/3Nb2/3)O3-xPbTiO3 (PMN-PT) and ZnSe transparent ceramics for applications in the mid-IR. The main challenge …
Community-Based Coastal Restoration: Long Term Impacts On Habitats And People In Volusia County, Rachel Wimmer
Community-Based Coastal Restoration: Long Term Impacts On Habitats And People In Volusia County, Rachel Wimmer
Electronic Theses and Dissertations
Coastal habitats provide invaluable economic and ecosystem services. However, coastlines are eroding at increasing rates due to anthropogenic and climate driven changes. Grey and green infrastructure solutions have been proposed to retard the decay of coastlines, with oysters serving as a popular living shoreline. Three community-based stabilizations that implemented living shorelines and engaged local communities in restoration efforts over the past decade in Volusia County were revisited to determine if they were successful and if they produced positive public perceptions of success. Chicken Island, which was restored after waves, boat wakes, tides, and adverse weather altered the natural shoreline, had …
Numerical Investigation And Optimization Of Pin Fins In Micro Heat Sinks, Fuad Ismayilov
Numerical Investigation And Optimization Of Pin Fins In Micro Heat Sinks, Fuad Ismayilov
Electronic Theses and Dissertations
Operating temperature in electronics applications is continuously increasing. Therefore, for the past few decades, high heat flux removing micro heat sinks are investigated in terms of heat transfer effectiveness. This study generally concentrates on improving the passive heat transfer techniques. Micro heat sinks used in experiments are fabricated using MEMS techniques. Resistance temperature detectors, RTDs, were used for temperature measurements. The experimental data was obtained for single and two phase flow regions; however, only single phase flow results were considered in numerical simulations. Numerical validations were performed on the micro heat sinks, including cylinder and hydrofoil shaped pin fins. Following …
Mode Coupling In Space-Division Multiplexed Systems, Huiyuan Liu
Mode Coupling In Space-Division Multiplexed Systems, Huiyuan Liu
Electronic Theses and Dissertations
Even though fiber-optic communication systems have been engineered to nearly approach the Shannon capacity limit, they still cannot meet the exponentially-growing bandwidth demand of the Internet. Space-division multiplexing (SDM) has attracted considerable attention in recent years due to its potential to address this capacity crunch. In SDM, the transmission channels support more than one spatial mode, each of which can provide the same capacity as a single-mode fiber. To make SDM practical, crosstalk among modes must be effectively managed. This dissertation presents three techniques for crosstalk management for SDM. In some cases such as intra-datacenter interconnects, even though mode crosstalk …
Commitment And Credibility In Fdi, Kathleen Sullivan
Commitment And Credibility In Fdi, Kathleen Sullivan
Electronic Theses and Dissertations
How can firms in foreign direct investment (FDI) best protect their assets from host government contract beach? FDI is the largest and most stable form of external financing to less developed countries (LDCs). It increases job growth, technological development, and efficiency in the host country, subsequently increasing economic development. Companies prefer to invest in countries that are less prone to contract breach. I propose that credibility of commitments can help explain variation in contract breach. I propose that firms are most likely to avoid contract breach when they are involved in supply chains and when the host country has a …
Evaluation Of Postoperative Air Leak And Chest Tube Drainage Systems After Pulmonary Resection, Kristina Jacobsen
Evaluation Of Postoperative Air Leak And Chest Tube Drainage Systems After Pulmonary Resection, Kristina Jacobsen
Electronic Theses and Dissertations
Postoperative air leaks are the most common complication after a pulmonary resection. There is no data in the literature comparing the traditional and digital chest drainage system after a robotic-assisted pulmonary lobectomy. In 182 eligible patients, this retrospective study evaluated the association between digital and traditional drainage systems with postoperative chest tube days, hospital length of stay, chest tube reinsertion during hospitalization, and 30-day readmission for pneumothorax following a robotic-assisted lobectomy. The groups did not differ significantly in terms of age, gender, BMI, smoking, adhesions or neoadjuvant therapy. Patients with the digital drainage system had a mean chest tube duration …
