The Ethicality And Political Skill Of Leaders And Subordinate Job Satisfaction: A Study Of Accounting Faculty, Donald L. Ariail

College of Graduate Studies: Theses & Dissertations

Using a sample of 539 accounting faculty teaching in the United States, this study explored perceptions of the ethicality and political skill of their direct supervisors and self-reported levels of job satisfaction. Ethicality was measured with the Ethical Leadership Scale (ELS) and the Behavioral Integrity (BI) Scale. These measures, which were highly correlated, were proxy measures for accounting faculty perceptions of the tone-at-the-top (TATT)—the ethical leadership under which faculty teach and research. The results indicated that while the majority of accounting faculty perceived their direct supervisor as being ethical, about a third (28% BI, 34.8% ELS) of them did not …

Educational Transformational Leadership And Teacher Organizational Citizenship Behavior Motives, Jeremy T. Davis

College of Graduate Studies: Theses & Dissertations

A principal’s leadership is a key part to the success of a school as their leadership guides both instructional and organizational leadership. Teachers often work beyond their formal duties to see that all of their students have their needs met including academic, social, and physical. The performance of such behaviors is referred to as Organizational Citizenship Behavior, which is when followers display behaviors that benefit the organization or its members beyond their current job requirements. This study investigated the relationship between principal’s transformational leadership and teachers’ Organizational Citizenship Behaviors and related motivating factors. Participants from a single suburban school district …

Evaluation Of Hemp Seed Meal As A Fish Meal Replacement Through Growth And Digestibility Trials In Striped Bass (Morone Saxatilis), Anthony Sample

College of Graduate Studies: Theses & Dissertations

Demand for seafood has continued to increase despite a stagnation in global wild-caught fisheries. Aquaculture has met this demand but suffers from numerous sustainability issues because of dependence on fish meal, which is unsustainable, sparking nutritional research into alternatives. Hemp seed meal has shown promise as an alternative due to its sustainable production and nutritional qualities. This study evaluated hemp seed meal as an alternative to fish meal through growth and digestibility trials with Morone saxatilis. A seven-week growth trial was conducted within a recirculating aquaculture system using a total of two control diets (commercial and constructed) and six …

A Study Of Reduced Activation Ferritic Martensitic Metal Core Wire For Wire Arc Additive Manufacturing, Alexander L. Reichenbach

College of Graduate Studies: Theses & Dissertations

This study seeks to determine the technical feasibility of fabricating reduced activation ferritic martensitic (RAFM) steel parts, using a wire arc additive manufacturing (WAAM) process. The WAAM process, manufactures a part by depositing layers of metal onto a substrate to build a large scale near net shape part. RAFM alloy steels are next generation steels designed to resist radiation effects in the radiation intense working environments, such as nuclear reactors. To achieve this, process development and testing to design the WAAM production process with the custom RAFM filler wire was carried out. Several welding waveform modes were tested, and it …

Toward Novel Optical Functionalities Through Intelligent Photonic Structure Design, Robert J. Williamson

College of Graduate Studies: Theses & Dissertations

Photonic Metamaterials is a branch of electromagnetism that has been of great interest in recent years. This is further enhanced by the introduction of micro- and nanofabrication methods capable of producing metamaterial structures with which it is possible to create specific optical phenomena. The study of iso-frequency k-surfaces is of importance when discussing optical interactions with media. Previous research found evidence of materials exhibiting k-surfaces of bi-hyperbolic nature, though they failed to find any further hyperboloid dispersions. In this thesis we describe the k-surface topologies and including tri- and tetra-hyperbolic as well as analyze the polariton-interactions that cause these hyperbolic …

Effects Of Titanium And Cerium Addition On Grain Size And Mechanical Properties Of Ductile Iron Castings, Shelton F. Fowler Iv

College of Graduate Studies: Theses & Dissertations

According to the Hall-Petch equation, the refinement of grains in metals increases the yield strength of the material. Austenite grain size influences the fineness of microstructural constituents in the ferrous alloys. It is well studied that cerium and titanium refine the austenite in steels and some gray irons, but no studies have been done to systematically explore the effects of cerium and titanium additions on austenite in ductile iron. This study sought to determine the effects of selected levels of these elements on the grain size within ductile iron. A hypoeutectic iron was chosen for testing as the proeutectic phase …

Developing And Validating A Machine Learning-Based Student Attentiveness Tracking System, Andrew L. Sanders

College of Graduate Studies: Theses & Dissertations

Academic instructors and institutions desire the ability to accurately and autonomously measure the attentiveness of students in the classroom. Generally, college departments use unreliable direct communication from students (i.e. emails, phone calls), distracting and Hawthorne effect-inducing observational sit-ins, and end-of-semester surveys to collect feedback regarding their courses. Each of these methods of collecting feedback is useful but does not provide automatic feedback regarding the pace and direction of lectures. Young et al. discuss that attention levels during passive classroom lectures generally drop after about ten to thirty minutes and can be restored to normal levels with regular breaks, novel activities, …

Cfd And Heat Transfer Analysis Of Rocket Cooling Techniques On An Aerospike Nozzle, Geoffrey Sullivan

College of Graduate Studies: Theses & Dissertations

In recent years the development of rocket engines has been mainly focused on improving the engine cycle and creating new fuels. Rocket nozzle design has not been changed since the late 1960s. Recent needs for reliable and reusable rockets, as well as advancements in additive manufacturing, have brought new interest into the aerospike nozzle concept. This nozzle is a type of altitude adjusting nozzle that is up to 90% more efficient than bell nozzles at low altitudes and spends up to 30% less fuel. Since the nozzle body is submerged in the hot exhaust gasses it is difficult to keep …

License Plate Image Quality Enhancement Utilizing Super Resolution Generative Adversarial Networks, Mark Moelter

College of Graduate Studies: Theses & Dissertations

This thesis focuses primarily on enhancing the image quality of blurred license plates through the use of Super-Resolution Generative Adversarial Networks (SRGANs) [1]. We propose a synthetic dataset with SRGAN model to promote blurred image quality enhancement, and allow for model evaluation on a multitude of image input and output size combinations. SRGAN is mainly used for low-resolution image enhancement, but by heavily blurring the input images, the model is tested on its ability to blindly deblur and upsample images to the desired super-resolution (SR) size. The model enhances the image quality to nearly that of the reference images. The …

Neosublime, Reframing The Philosophical, Kathy Varadi

College of Graduate Studies: Theses & Dissertations

Why have the sunsets and sunrises become so amazingly colorful and awe inspiring recently? Eighteenth century philosophers said such events were examples of the sublime. They defined the sublime as that which is the most absolutely great combined with an underlying element of fear usually caused by the actions of God. This infers that the sublime is something that you can’t fully understand or wrap your head around and leaves you speechless and spell bound. Contemporary art critics say that the sublime is no longer applicable to art because it has been overused. I disagree, and in my art, I …

Cryptography Through The Lens Of Group Theory, Dawson M. Shores

College of Graduate Studies: Theses & Dissertations

Cryptography has been around for many years, and mathematics has been around even longer. When the two subjects were combined, however, both the improvements and attacks on cryptography were prevalent. This paper introduces and performs a comparative analysis of two versions of the ElGamal cryptosystem, both of which use the specific field of mathematics known as group theory.

Evaluation Of Tidal Fresh Forest Distributions And Tropical Storm Impacts Using Sentinel-2 Msi Imagery, Galen Costomiris

College of Graduate Studies: Theses & Dissertations

Situated in the transitional zone between non-tidal forests upstream and tidal fresh marshes downstream, tidal fresh forests occupy a unique and increasingly precarious habitat. The threat of intensifying anthropogenic climate change, compounded by the effects of historical logging and drainage alterations, could reduce the extent of this valuable ecosystem. The overall goals of this project were to identify forest communities present in the Altamaha tidal fresh forest; develop satellite imagery-based classifications of tidal fresh forest and tidal marsh vegetation along the Altamaha River, Georgia; and to quantify changes in vegetation distribution in the aftermath of hurricanes Matthew and Irma. Based …

Biomimetic Synthesis Of Palladium Nanoparticles For Catalytic Application, Emily A. Groover

College of Graduate Studies: Theses & Dissertations

The synthesis of palladium nanoparticles (Pd NPs) using materials-directed peptides is a novel, nontoxic approach which exerts a high level of control over the particle size and shape. This biomimetic technique is environmentally benign, featuring nonhazardous ligands and ambient conditions. Nanoparticles are extremely reactive catalysts, boasting a large surface-to-volume ratio when compared to their bulk counterparts. The rational design of these nanoparticles using peptides has been very successful in aqueous environments, but no research has been done to apply it in organic systems. As such, the biomimetic synthesis of Pd NPs in an organic system is here investigated, with ethanol …

Attendance Of International Students At U.S. Colleges And Universities, Nader H. Shooshtari

AMTP Proceedings 2022

U.S. colleges and universities have traditionally been lauded as a Mecca for attracting international students. Touted as offering the best higher education in the world, international students from around the world have traditionally flocked to U.S. educational institutions. This influx brought opportunities for international students while providing U.S. higher education institution additional revenue and a diverse student body. Beginning with the Trump Administration’s inward tilt, the welcome mat for international students was removed and the COVID pandemic added to the uncertainty and difficulty of accepting international students to U.S. and indeed much of the western countries that traditionally served as …

First Impressions Matter! An Experiment Comparing Autonomous And Controlling Language In Course Syllabi, Jully Paola Merchán Tamayo, Meredith Rocchi, Jenepher Lennox Terrion, Simon Beaudry

International Journal for the Scholarship of Teaching & Learning

The course syllabus serves as an important first contact between professors and students in university courses and the language used in a syllabus can influence students’ first impressions of the professor and expectations for the course. Existing research in Self-Determination Theory has shown that autonomy-supportive language leads to increased positive outcomes for students compared to controlling language. The objective of the present studies was to compare an autonomy-supportive with a controlling syllabus to see how students felt when reading the syllabus (Study 1), and how the syllabus related to their impressions of the professor, reported motivation, and expectations for the …

Student Preferences In Using Affordable Learning Materials To Teach Research Methods Online, Phillip D. Grant, Elizabeth M. Pope

International Journal for the Scholarship of Teaching & Learning

This basic qualitative study assessed students’ perceptions of affordable learning materials in an asynchronous master’s level research methods course at a regional university. Students preferred instructor-created mini-lectures (45%) more than required readings (39%), supplementary items concerning a specific topic (7%), sample studies (5%), CITI training modules (3%), and continuing education materials (2%). We found that students tended to prefer material that offered foundational information about research methods. Students also preferred material that “translated” academic language. Students preferred materials that were compatible with their perceived learning style. Finally, students preferred materials that related research methods to their own professional practice.

Exploring The Effects Of Team-Based Learning In A Preservice Reading Methods Course, Lauren R. Brannan, Hannah D. Szatkowski

International Journal for the Scholarship of Teaching & Learning

Teacher educators are tasked with preparing preservice teachers with both the content and pedagogical knowledge and skills to teach children to read. In this study we investigated the use of team-based learning (TBL) in a reading methods course as a framework for improving student learning outcomes. TBL is an instructional approach that has been used across a variety of fields in higher education but has only recently made its way into teacher preparation programs. Using mixed methods, we compared TBL to the traditional lecture to explore whether participation in TBL affected preservice elementary teachers’ level of preparation for class, achievement …

The Agrarian Road To Peace: Henry Morgenthau's Post-War Planning For Germany, Logan W. Ray

Armstrong Undergraduate Journal of History

In September 1944, allied leaders Franklin D. Roosevelt and Winston S. Churchill met at Quebec to discuss the post-war planning of Germany. Treasury Secretary Henry Morgenthau accompanied Roosevelt to this conference and put forward his agrarian plan for Germany which would bear his name, the Morgenthau Plan. His plan called for the industrial reorganization of Germany and transition it to a farming community, thus making the country incapable of war. Though his plan was accepted at the Quebec Conference, its fierce opposition from the War Department and its leak to the press pressured Roosevelt to abandon the plan.

Effects Of Anharmonicity In A Dual-Sagnac Interferometer, Stephen Thomas

Honors College Theses

A recent experiment implemented a dual Sagnac atom interferometer (AI) for rotation sensing using a Bose-Einstein condensate (BEC) confined in a TOP-trap potential. The BEC is split twice by laser light to create two pairs of counter-orbiting clouds in a lowest-order harmonic potential with each pair acting as a separate Sagnac interferometer. After one orbit the two overlapping cloud pairs are split again and the interference patterns are inferred from the population of atoms in the zero-momentum state. We have simulated the impact of the presence of anharmonic terms in the potential on the performance of the AI as measured …
