Evaluation Of Soybean [Glycine Max (L.) Merr.] Cultivar Response To Prophylactic Fungicide Application, Steven B. Stoker

Theses and Dissertations

Soybean growers in the southern United States commonly deal with disease issues that can limit yield potential. As a result, growers have adopted prophylactic fungicide application targeted at specific growth stages as a standard management practice. However, yield responses to prophylactic applications have become sporadic over time. One major change that has occurred is adoption of cultivars with improved disease tolerances. Therefore, the objective of this research was to evaluate yield response of cultivars representing multiple genetic backgrounds to fungicides applied prophylactically at the R4 soybean growth stage. Experiments were conducted in 2020 and 2021 to determine the yield impact …

United We Stand? Investigating The Impact Of Unified Dues Agreements Between State And National Career & Technical Education (Cte) Professional Organizations On Cte Funding In The Southern States, Justin Ryan Hall

Theses and Dissertations

Career and Technical Education (CTE) teachers have long been active in lobbying the federal and state governments in support of CTE through their professional organizations, but these are not traditionally considered interest groups. This study sought to determine if the formal relationships—dues agreements—between the two largest national professional organizations, and their state affiliates had an impact on state funding for CTE. The impacts of professional organization unity, membership rates, and lobbying expenses on state-level CTE funding were analyzed through the lens of interest group theory, a subfield of political science. Within this population (N = 13), 1) a link …

How Formal Music Training Affects Executive Functions In Middle School Band Students, Zachary C. Anderson

Honors College Theses

My thesis project explored the relationship between a formal music training experience and executive functions in a middle school band classroom. Executive functions are working memory, inhibition, and cognitive flexibility which allow us to gain and focus our attention on specific tasks. Participants in the study were two groups of middle school students: a sixth-grade class with no previous musical experience and an eighth-grade class with two years of band classes.

Hydraulic Redistribution Under Saline Conditions, Josh Gottlieb

Civil and Environmental Engineering Undergraduate Honors Theses

Water scarcity and soil salinity are dual stressors for plants in arid, salt-affected ecosystems. Hydraulic redistribution, a hydraulic adaptation which moves water through plant roots into dry or saline soil regions along potential gradients, aids plant survival in stressful environments. Recent theory regarding hydraulic redistribution proposes limitations on the process within saline soils. This study applies a minimalist resistor-capacitor model of the soil-plant-atmosphere system to the experimental conditions of a 2010 study investigating hydraulic redistribution in a salt affected area. The effectiveness of the model is evaluated, and a sensitivity analysis is conducted to identify key dynamics affecting the moisture …

Examining The Relationship Between Stomiiform Fish Morphology And Their Ecological Traits, Mikayla L. Twiss

All HCAS Student Capstones, Theses, and Dissertations

Trait-based ecology characterizes individuals’ functional attributes to better understand and predict their interactions with other species and their environments. Utilizing morphological traits to describe functional groups has helped group species with similar ecological niches that are not necessarily taxonomically related. Within the deep-pelagic fishes, the Order Stomiiformes exhibits high morphological and species diversity, and many species undertake diel vertical migration (DVM). While the morphology and behavior of stomiiform fishes have been extensively studied and described through taxonomic assessments, the connection between their form and function regarding their DVM types, morphotypes, and daytime depth distributions is not well known. Here, three …

Zur And Zinc Increase Expression Of E. Coli Ribosomal Protein L31 Through Rna-Mediated Repression Of The Repressor L31p, Rebecca A Rasmussen, Suning Wang, Jeannie M Camarillo, Victoria Sosnowski, Byoung-Kyu Cho, Young Ah Goo, Julius B Lucks, Thomas V O'Halloran

2020-Current year OA Pubs

Bacteria can adapt in response to numerous stress conditions. One such stress condition is zinc depletion. The zinc-sensing transcription factor Zur regulates the way numerous bacterial species respond to severe changes in zinc availability. Under zinc sufficient conditions, Zn-loaded Zur (Zn2-Zur) is well-known to repress transcription of genes encoding zinc uptake transporters and paralogues of a few ribosomal proteins. Here, we report the discovery and mechanistic basis for the ability of Zur to up-regulate expression of the ribosomal protein L31 in response to zinc in E. coli. Through genetic mutations and reporter gene assays, we find that Zur achieves the …

Numerical And Approximate Analytic Solutions Of Second- Order Nonlinear Boundary Value Problems, Chein-Shan Liu, Jian-Hung Shen, Yung-Wei Chen

Journal of Marine Science and Technology–Taiwan

The shooting method consists of guessing unknown initial values, transforming a second-order nonlinear boundary value problem (BVP) to an initial value problem and integrating it to obtain the values at the right end to match the specified boundary condition, which acts as a target equation. In the shooting method, the key issue is accurately solving the target equation to obtain highly precise initial values. Due to the implicit and nonlinear property, we develop a generalized derivative-free Newton method (GDFNM) to solve the target equation, which offers very accurate initial values. Numerical examples are examined to show that the shooting method …

Optimization Of Circular Silencers Internally Hybridized With Multiple Reverse Chambers Using The Ga Method, Min-Chie Chiu, Ying-Chun Chang, Tian-Syung Lan, Ho-Sheng Chen

Journal of Marine Science and Technology–Taiwan

A noise abatement method using an eigen function in conjunction with an optimizer (Genetic Algorithm) under a space-constrain situation is proposed in this study concerning a high order wave propagation effect. An eigen function is used to describe an acoustical field and shorten the acoustical model in a four-pole transfer matrix form. The system’s four-pole matrix estimates the Transmission Loss (TL) for the silencers by multiplying individual four-pole matrices.

Additionally, a case study of an air compressor’s broadband noise elimination is introduced. Three types of circular reverse silencers (silencers A-C) internally hybridized with multiple straight chambers are adopted to efficiently …

The test-bed was used to simulate the Doppler spectra based on Barrick’s (1972) theory by using the input of the directional wave spectra. The typhoon wave spectra …

Of Crowns, Pilgrims, And Non-Asinine Mules, Moshe Gold

Jesuit Higher Education: A Journal

John O’Malley, S.J.’s emphasis on rhetoric challenges students to reconsider not only the significance of the history of rhetoric in relation to St. Ignatius’ texts, but also the importance of rhetoric in their own discourses. In this essay, I focus on one specific event in Ignatius’ Acts, an event replete with rhetorical, textual, biblical (both the New Testament and Tanakh, the Hebrew scriptures), and historical considerations, but which, surprisingly, does not appear as a major focus in John O’Malley, S.J.’s voluminous books: Ignatius on a mule, encountering “the Moor” (un moro). I outline a method of guiding students through …

Educators’ And Parents’ Attitudes Toward The Inclusion Of Students With Emotional And Behavior Disorders, Shannon L. Howze

Dissertations

Educating students with emotional and behavior disorders (EBD) has historically been a difficult task for educators (McKenna et al., 2021). The general education setting comes with many barriers when attempting to include students with EBD to the equation. Parents are instrumental to the success of their students with EBD regardless to the setting. Educators may lack in the skills needed to communicate, educate, and understand students with EBD. Without educators and parents collectively communicating and collaborating, students with EBD will not have the opportunity to have the positive experiences and outcomes to be successful. Applying the theoretical frameworks of Bandura’s …

Dissertations

This study examined sexual assertiveness among female undergraduate students at an institution of higher education in the southeastern United States from the context of the social-ecological model. An online survey instrument examined sexual assertiveness, sexual communication self-efficacy, campus climate, and sexual scripts. Structural equation modeling was used to examine the relationships between these variables and all variables significantly predicted sexual assertiveness individually, but when examining the relationships collectively, only sexual communication self-efficacy and campus climate remained significant predictors of sexual assertiveness.

The Impact Of A Five-Day Number Sense Intervention On High School Student's Quantitative Reasoning Skills And Self-Efficacy, Rebecca Steele-Mackey

Dissertations

Understanding numerical quantities and applying this knowledge in practical applications is essential throughout life. A well-developed number sense comes from learning foundational skills and continuing to rely on these skills and concepts in higher mathematical education as well as in adulthood. Prior research shows that K-8 students lack a conceptual understanding of fraction, decimal, and percentage concepts (NCTM, 2009). While there is literature that identifies a deficit in these mathematical areas, there is a need to examine possible activities and interventions that can be performed throughout secondary education courses that support growth in students' conceptual understanding of rational number concepts. …

The Presence Of Relational Trust In Teacher-Principal Relationships And The Correlation Of Teacher Intent-To-Persist And Teacher Efficacy, Maryum Bilal

Dissertations

Principals and teachers must work together for students to be academically successful. Teachers directly influence the students, and principals directly affect the teachers. Before students' success can occur, the principal and teachers must have a relationship. The development of trust begins with leaders who have quality relationships with their teachers (Bryk & Schneider, 2002). When teachers trust their principals, teachers are loyal and develop self-efficacy. According to Lacks and Watson (2018), teacher self-efficacy is developed through significant interactions with the principal, making teachers feel better about themselves and their collective mission, and they become more effective in the classroom. Trust …

Strategic Human Resource Management Practice Integration And Organizational Ambidexterity In Vuca Times, Gizzatta Cook

Dissertations

ABSTRACT

The failure rate of business strategy implementation hovers around 50% due to a lack of organizational ambidexterity in the realities associated with a four-dimensional paradigm referred to as a volatile, uncertain, complex, and ambiguous (VUCA) environment (Chattopadhyay et al., 2017). Anwar and Abdullah (2021) state that organizational success depends highly on how well organizational leaders manage and administer their human resource management practices. Today's successful organizations must adapt to societal changes to survive and thrive (Chattopadhyay et al., 2017).

Surviving and thriving beyond today’s organizational constraints also involves a business's ability to demonstrate organizational ambidexterity. Organizational ambidexterity is the …

Lateral Decubitus And Prone Positioning: An Objective Structured Clinical Evaluation, David Hesley-Hernandez, James Bailey

Doctoral Projects

Improper positioning of patients in the lateral decubitus or prone positions can lead to significant complications, including but not limited to: airway and invasive line loss, physiologic derangements, soft tissue injury, and peripheral nerve injuries (PNI) (Barash et al., 2017; Butterworth et al., 2018). Chui et al.’s (2018) analysis found that PNIs accounted for 12% of anesthesia malpractice since 1990, making PNIs costly. PNIs effects are not limited to cost and result in increased lengths of stay, increased pain levels, and decreased quality of life (Wojtkiewicz et al., 2015). The massive effect poor positioning can have requires that the anesthesia …

Objective Structured Clinical Examination For Intraoperative Hypotension And Hypertension Management, Andrew Mcginity, James David Ingram

Doctoral Projects

Managing intraoperative hypotension and hypertension is a non-technical skill anesthesia providers need to maintain patient safety. Upon transitioning from didactic training to clinical training, SRNAs may find it difficult to manage a patient’s blood pressure intraoperatively. The ultimate consequence of the delayed or improper treatment of intraoperative blood pressure perturbations is end-organ damage at the patient’s expense. Unintentionally causing a patient harm will lead to an SRNA losing confidence in their abilities. This OSCE is intended to increase SRNA confidence and competence regarding intraoperative hypotension and hypertension management before entering the clinical arena.

The hypotension and hypertension management tools and …
