Involvement Of Jak/Stat Signaling And A Basement Membrane-Associated Protein During Air Sac Primordium Development In Drosophila Melanogaster, Nathan Anthony Powers

Masters Theses & Specialist Projects

Tumor metastasis currently presents the greatest obstacle for effective cancer remediation. Metastatic growth necessitates both degradation of a specialized form of extracellular matrix (ECM) known as the basement membrane (BM) and the invasion of surrounding tissues thereafter. The thoracic air sacs of fruit flies (Drosophila melanogaster), which develop and operate in a fashion comparable to the human lung, provide a unique model for identifying and characterizing factors that contribute to its own development as well as tumoral invasion. We investigated the involvement of both Janus kinase (JAK)/Signal transducer and activator of transcription (STAT) signaling and a BMassociated protein during the …

To Cheat Or Not To Cheat: Impact Of Learning Disability Status On Reasons For Cheating, Mckenzie Elizabeth Perdew

Masters Theses & Specialist Projects

Academic cheating frequency, motivating factors for cheating, and student reasons for cheating have been studied extensively for decades, but nearly all of the research has been conducted with typically-developing students. To date, only one published study has examined cheating among students with learning disabilites, despite over 2 million students in American schools having been diagnosed with a learning disability.

Students who engage in academic cheating, as well as students who have learning disabilities, are more likely to have low levels of self-efficacy, hold more performance goal orientations, and have higher levels of impulsivity. Therefore, in the present study, individuals with …

Developing A New Sensing Technology For Double-Stranded Dna Detection Utilizing Engineered Zinc Finger Proteins And Nanomaterials, Dat Thinh Ha

Masters Theses & Specialist Projects

A specific double-stranded DNA sensing system is of great interest for diagnostic and other biomedical applications. Zinc finger domains, which recognize double-stranded DNA, can be engineered to form custom DNA-binding proteins for recognition of specific DNA sequences. As a proof of concept, a sequence-enabled reassembly of TEM-1 β- lactamase system (SEER-LAC) was previously demonstrated to develop zinc finger protein (ZFP) arrays for the detection of a double-stranded bacterial DNA sequence. Here, we implemented the SEER-LAC system to demonstrate the direct detection of pathogenspecific DNA sequences present in E. coli O157:H7 on the lab-on-a chip. ZFPs customdesigned to detect shiga toxin …

Indirect Greenhouse Gas Dynamics In Karst Groundwater Systems Under Agricultural Land Use, Stacy Wayne Antle

Masters Theses & Specialist Projects

Greenhouse gases (GHGs) are a major global environmental concern, because their concentrations have continuously increased over the past few centuries, due to global population growth, fossil fuel dependency, and the Industrial Revolution. Since these gases are naturally occurring phenomena, they will never be completely eliminated. Efforts to reduce them span numerous scientific attempts, with minimal improvements in reducing their atmospheric concentrations. In agricultural land practices, greenhouse gases are common byproducts that affect the atmosphere and, potentially, the groundwater where livestock and fertilizers are key contributors. Little is known about the fate of such greenhouse gases in dissolved form, known as …

Masters Theses & Specialist Projects

Much of the pioneering work on caves of the Cumberland Plateau (province spanning Tennessee, Kentucky, Alabama, and Georgia) has been stratigraphically located within the Mississippian Bangor and Monteagle Limestones, wherein some of the region’s largest and most spectacular caves occur. Of interest to the understanding of this karst landscape, but severely underrepresented in the literature thereof, are caves and karst features in a heterogeneous sequence of clastics and carbonates known collectively as the Pennington Formation (Upper Mississippian). This work consisted of a regional study of Pennington caves on the western Cumberland Plateau escarpment (Alabama and Tennessee), and a case study …

Effects Of Variable Resistance Training On Kinetic And Kinematic Outcomes During A Heavy Conventional Deadlift, Timothy J. Gerking

Masters Theses & Specialist Projects

Variable Resistance Training (VRT), loading elastic band tension on a barbell, has shown improvements in force, power, and velocity. Studied extensively in the squat and bench press, VRT is less researched in the context of the deadlift. Additionally, while no acute VRT deadlift studies exist where intensity was ≥ 90% 1- RM, some heavy VRT studies suggest that at approximately 90% 1-RM, less band tension (BT) is required to enhance force and power than seen at lower intensities in existing research. Therefore, the purpose of this study was to determine the effects of VRT on peak relative vertical ground reaction …

Cultural And Narrative Shifts Of Nineteenth Century Children's Literature In Hawthorne's Wonder Book For Girls And Boys, Kristen Clark Brandt

Masters Theses & Specialist Projects

Both folklorists and literary critics have been drawn to Nathaniel Hawthorne’s body of work because of his distinctive style and incorporation of folk motifs. Such motif-spotting presents no challenge in Hawthorne’s juvenile literature like his retellings from Greek mythology in Wonder Book for Girls and Boys; however, contemporary folklore redirects the focus of this scholarship to “how particular literary uses of folklore fit into a larger, more fundamental concept of what folklore is and how and what folklore communicates” (de Caro & Jordan 2015:15). Hawthorne’s work interacts with other forms of cultural expression in the nineteenth century such as dominant …

Nontraditional Students Success In Compressed Courses Within A Community College Cohort, Elizabeth Kinter Tanner

Masters Theses & Specialist Projects

Nontraditional students are an untapped population for American higher education institutions. Private baccalaureate-granting universities have taken the lead on creating programs for this population’s needs. These programs typically include combinations of online instruction, cohorts, compressed or accelerated courses, and prior learning assessment. Similarly constructed programs for nontraditional students at public community colleges are less common. A review of the Council for Accelerated Programs’ website reveals only twelve of the 98-member institutions are community or technical colleges, and only one is in California (Council for Accelerated Programs, n.d.). In 2016, Shasta-Tehama-Trinity Joint Community College District in California created the Accelerated College …

Mass-Transport Deposits In The Northern Gulf Of Mexico And Their Implications For Hydrocarbon Exploration, Michael Raymond Arthur

Masters Theses & Specialist Projects

This study investigates Mio-Pliocene mass-transport deposits (MTDs) in an understudied, hydrocarbon-rich region of the northeastern Gulf of Mexico. The research utilizes a high-quality 3D seismic dataset with an area of 635 km2, along with wireline logs and biostratigraphic data. With the help of quantitative seismic geomorphology techniques, detailed mapping of MTDs suggests a complex erosional and depositional history. Deposition of a MTD unit resulted in a 180 m topographic high that substantially influenced the distribution and morphology of subsequent MTDs, specifically the bifurcation of later mass-transport flows. This bifurcation contributed to the generation of a non-shielded erosional remnant with an …

Synthesis Of A Platinum Triamine Complex And Its Interactions With Guanosine 5’- Monophosphate And N-Acetylmethionine, Manal El Masri

Masters Theses & Specialist Projects

Cisplatin (cis-diamminedichloroplatinum(II)) and its analogs are known to form 1,2-intrastrand cross-links with guanine bases that lead to DNA distortion and are responsible for cytotoxicity. Reaction with proteins, especially at methionine residues, could also be responsible for cytotoxicity (Sandlin, R. D. et al. 2010). A new tridentate platinum(II) complex with a piperazine ring was successfully designed and synthesized. In this complex, the platinum is coordinating to all three nitrogens of (1,2- dimethylaminoethylpiperazine), which makes it a Platinum triamine compound. A series of chemical reactions of this compound with guanosine 5’-monophosphate (5’-GMP) and N-acetylmethionine (N-AcMet) were conducted under different conditions. Reactions with …

Unroofing History Of The Northwestern Ethiopian Plateau: Insights From Low-Temperature Apatite Thermochronology, Shelby Bowden

Masters Theses & Specialist Projects

The geology of Ethiopia is dominated by the Ethiopian Plateau that is similar in elevation to, but aerially larger than, the Colorado Plateau. Several rivers have incised through the plateau, creating gorges that reach up to 1.5 km in depth. The plateau uplifted to its current elevation and was subsequently incised sometime after the Oligocene flood basalt event that signaled the arrival of the African Superplume below Kenya and Ethiopia. Due to its size and extent, published climate modeling has indicated that Late Cenozoic plateau formation could have been a driving force in the East African Cenozoic climate changes. Although …

Monitoring And Evaluating The Influences Of Class V Injection Wells On Urban Karst Hydrology, James Adam Shelley

Masters Theses & Specialist Projects

The response of a karst aquifer to storm events is often faster and more severe than that of a non-karst aquifer. This distinction is often problematic for planners and municipalities, because karst flooding does not typically occur along perennial water courses; thus, traditional flood management strategies are usually ineffective. The City of Bowling Green (CoBG), Kentucky is a representative example of an area plagued by karst flooding. The CoBG, is an urban karst area (UKA), that uses Class V Injection Wells to lessen the severity of flooding. The overall effectiveness, siting, and flooding impact of Injection Wells in UKA’s is …

Identifying Clinical Distinctions Between Nonsuicidal Self-Injury And Eating Disorders In Adolescents, Natalie Marie Perkins

Masters Theses & Specialist Projects

Eating disorders and non-suicidal self-injury (NSSI) are pervasive behaviors that typically begin in early to mid-adolescence. They commonly co-occur, resulting in increasingly negative psychological and physical outcomes than either behavior alone. Emotion reactivity and family functioning have been studied in relation to both eating disorders and NSSI. Both constructs have demonstrated strong relationships to these behaviors, but emotion reactivity appears to be more strongly associated with NSSI, while family functioning appears to be more strongly related to eating disorders. The current study sought to determine whether emotion reactivity and family functioning could differentiate between adolescents with only an eating disorder, …

Interval Sprinting: Impact On Reading Fluency And Self-Efficacy, Laura C. Duncan

Masters Theses & Specialist Projects

Reading fluency is the ability to decode connected text with accuracy and speed (Archer, Gleason, & Vachon, 2003; Daly, Neugebauer, Chafouleas, & Skinner, 2015), and is generally measured by how many words a student can read in a minute. Selfefficacy is the judgment people make about their own performance levels for specific abilities, which affects their motivation and behaviors concerning those abilities (Bandura, 1977). It is unknown if repeated reading or interval sprinting reading interventions have an effect on reading self-efficacy. Two third-grade students with low reading fluency participated in an alternate treatment design, using repeated reading and interval sprinting …

Investigations Of Biotremors In The Veiled Chameleon (Chamaeleo Calyptratus), Kathryn C. Laslie

Masters Theses & Specialist Projects

While substrate-borne vibrations are utilized by different reptile species, true conspecific communication via biotremors has not yet been demonstrated in reptiles. This study follows a preliminary report that the veiled chameleon (Chamaeleo calyptratus) could produce biotremors in communicative contexts. I tested chameleon behavioral sensitivity to vibrations by placing them on a dowel attached to a shaker emitting vibrations of 25, 50, 150, 300, and 600 Hz and then measured their changes in velocity before and after the stimulus. I then paired chameleons in various social contexts [anthropogenic disturbance (human disruption of animal); dominance (malemale; female-female C. calyptratus); courtship (male-female C. …
