Preparing The Next Generation Of Music Teachers: Illuminating Motivations Of Nebraska Preservice Teacher Mentors, Emily Marie Chapman

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This mixed methods study examined factors influencing practicing educators' decisions to mentor preservice teachers in Nebraska. Guided by Expectancy-Value-Cost Theory, the study utilized a sequential explanatory design, integrating a quantitative survey design and qualitative phenomenological interview. Findings indicated that educators' belief in their mentoring ability or Expectancy-Ability Belief (EAB) significantly predicted their willingness to mentor, with PK-12 music educators exhibiting higher EAB scores than elementary or high school music educators. Qualitative insights highlighted reciprocal benefits of mentoring, such as skill development and professional growth. The impact of the COVID-19 Public Health Emergency on mentoring experiences varied among participants. Recommendations included …

Approximation Via Degree Reduction Of Nonlinearities With Applications To Turbulent Flows, Flame Fronts, And Magnetohydrodynamics, Matthew Enlow

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

We perform an analytical and computational investigation on the effectiveness of a locally bounded truncation function, which we call a calming function, when applied to the nonlinear terms of several dissipative partial differential equations. In particular, the 3D Navier-Stokes equations of incompressible fluid flow, the 2D Kuramoto-Sivashinsky equations of laminar flame fronts, and the 2D MHD-Boussinesq equations of magnetohydrodynamics. Each of these equations have open questions about the global existence and uniqueness of their solutions. These calming functions effectively reduce the algebraic degree of select nonlinear terms, thus one can verify global wellposedness for these "calmed systems." More specifically, in …

Examining Theoretically Derived Mechanisms Underlying The Relationships Between Sexual Arousal, Alcohol Use History, And Sexual Aggression, Kailey Ann Richner

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Various interventions have attempted to reduce the rates of sexual violence perpetrated by college men; however, meta-analyses suggest interventions need to further evaluate theoretically derived mechanisms to improve outcomes (Malamuth et al., 2018; DeGue et al., 2014; Vladutiu, et al., 2011). To address this concern, the present study utilized the Integrated Theory of Sexual Offending (ITSO; Ward et al., 2016; Ward & Beech, 2008; 2006) to explore mechanisms underlying the relationships between sexual arousal, alcohol use history (AUH), and sexual aggression. Working memory, impulsivity, and affective forecasting paradigms were selected to map onto the ITSO’s neuropsychological mechanisms. The interaction between …

Singing While Acting: A Mixed Methods Study Of Classical Singers’ Application Of The Chekhov And Meisner Acting Methods, Amy C. Johnson

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

When considering the minimal acting training incorporated into most voice performance programs, it is understandable why many singers struggle to balance vocal demands with acting demands. Furthermore, the expectations on singers to deliver authentic and nuanced performances are increasing as opera evolves. There is little in-depth understanding of classical singers’ experiences with applying specific acting techniques to their singing. There is also little information about how different acting methods may affect classical singing. This mixed methods collective case study aims to identify the impact of training in a specific acting method on classical singing. The qualitative strand focuses on the …

Supporting The Creative Side Of Creative Coding: Helping Students Wield Code In The Pursuit Of Their Own Dreams, Gretchen K. Larsen

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Creative coding has become more common in art and new media schools, however research describing how teachers navigate the unique challenges of teaching code as a creative medium is limited. This paper presents the details of a creative coding course designed to support the ‘creative’ side of creative coding. As a result of this research, I present a framework for supporting the ‘creative’ side of creative coding, which connects to arts-based education theories, modified for the creative code context. This paper asks—what helps students use creative coding as an artistic medium in the pursuit of their own questions and meaning? …

Navigating Mental Health During Covid-19: Considerations Of Childhood Adversity, Pandemic Stress, And Loneliness, Linnea Rose Swanson

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

The purpose of this dissertation study was twofold. First, to determine if the addition of bullying victimization to the Adverse Childhood Experiences (ACEs) Questionnaire (Felitti et al., 1998) would result in a stronger measure of childhood adversity; second to examine the interaction between ACEs, pandemic stress, loneliness, and internalizing symptoms in a sample of young adults living in the United States during the COVID-19 pandemic. ACEs are linked to negative outcomes in adulthood including mental health problems, stress, and loneliness. During the pandemic, increased levels of stress and loneliness were associated with higher rates of internalizing disorders among young adults. …

Occupational Therapy’S Role In Developmental Programming At Early Childhood Education And Childcare Centers: A Qualitative Study, Alexis N. Foehrkolb, Jenna Lenhart, Hayley Woods, Madison Wetzel, Breanna Adkins, Sueann R. Woods

Graduate Student Scholarship

This research study aimed to discover what strategies of developmental programming are integrated into early childhood curriculum, whether occupational therapy had a role in the formation of the guidelines, and the importance of early intervention on child development. A case study with ethnographic methods was used, including observations and interviews, to gain an understanding of how sociocultural phenomena affect rural childcare centers in Morgantown, West Virginia. Data was collected and coded into 14 themes, and then analyzed by student researchers. Results from interview data found that daycare teachers are given the choice to follow provided lesson plans or individualize their …

Financial Literacy And Ipo Underpricing, Xiaoran Jia, Kiridaran G. Kanagaretnam, Chee Yeow Lim, Gerald J. Lobo

Research Collection School Of Accountancy

Using an international sample of IPO firms and two country-level measures of financial literacy, we find strong evidence that financial literacy is negatively associated with IPO underpricing. In cross-sectional analyses, we find that the effect of financial literacy in reducing IPO underpricing is more pronounced when the information environment is less transparent. Employing path analysis, we document that information friction, firm transparency, and stock market participation are mechanisms that mediate this relationship. Our study contributes to and extends the literature by providing strong evidence that citizens' financial literacy has an important and consistent influence on IPO underpricing.

The Governance Of Director Compensation, Lily Fang, Sterling Huang

Research Collection School Of Accountancy

The average total compensation of directors in U.S.-listed companies was $342,030 in 2020, 5.06 times the median household income. Directors set their own pay, giving rise to potential self-dealing. We argue and document that in the presence of self-dealing, external mechanisms such as legal standards act as effective means of governance. Following a landmark Delaware court ruling that subjected director pay to a more stringent legal standard, Delaware-incorporated firms reduced director compensation relative to non-Delaware firms and experienced positive and non-transient stock price reactions. Our results indicate that proper governance of director compensation enhances firm value.

Do Firms With Technological Capabilities Rush In? Evidence From The Timing Of Licensing Of Stanford Inventions, Young-Choon Kim, Reddi Kotha, Mooweon Rhee

Research Collection Lee Kong Chian School Of Business

This study investigates the influence of licensees’ technological capabilities on the timing of technology licensing in university technology commercialization. Drawing on the appropriation-collaboration tension from the literature on university technology licensing and intellectual property management, we propose that while the licensee’s technological capabilities drive early licensing by averting technological obsolescence, this effect diminishes significantly with an overlap in the technological domain of the focal invention due to expropriation concerns. Cox regression analysis of Stanford University’s invention dataset confirmed our hypotheses. This research reveals that technology licensing experiences delays with the most suitable licensees, namely, those with strong technological capabilities in …

Bridging The Chasm Between Intentions And Behaviors: Developing And Testing A Construal Level Theory Of Internalwhistle-Blowing, Abhijeet K. Vadera, Ann E. Tenbrunsel, Kristina A. Diekmann

Research Collection Lee Kong Chian School Of Business

The recent wave of corporate scandals has necessitated a more systematic investigation of internal whistle-blowing as a potential way to prevent wrongdoing. Our understanding of whistle-blowing, however, has been hampered by a deep chasm that exists between employees’ intent to blow the whistle and their whistle-blowing behaviors. We argue that to fully bridge this gap, we need to consider employees’ cognitive states at the time of whistle-blowing intentions versus behaviors and to link these cognitive states to the ethical systems within the organization’s ethical infrastructure to understand which systems are more effective in cultivating whistle-blowing intentions and which systems help …

Despite their significant impact on human life in the Afrotropical Region, Diptera remain understudied. For a large part this is due to a lack of Diptera taxonomic experts and collection curators from the Afrotropical Region (except for South Africa perhaps), the difficulties some developing countries face in maintaining collections, and the low number of digitised specimens. This impedes the use of these Diptera collections for identification services, taxonomic and phylogenetic research, and other biological research areas. The dire need for knowledge transfer and training of young and emerging entomologists in the Afrotropical Region has prompted the Royal Museum for Central …

Tungiasis Among Children In Kenya Is Associated With Poor Nutrition Status, Absenteeism, Poor School Performance And High Impact On Quality Of Life, Lynne Elson, Christopher Kamau, Sammy Koech, Christopher Muthama, George Gachomba, Erastus Sinoti, Elwyn Chondo, Eliud Mburu, Miriam Wakio, Jimmy Lore, Marta Maia, Ifedayo Adetifa, Benedict Orindi, Phillip Bejon, Ulrike Fillinger

Tungiasis is a highly neglected tropical skin disease caused by the sand flea, Tunga pene-trans. The flea burrows into the skin inducing a strong inflammatory response, leading to pain and mobility restrictions with potential impacts on quality of life. Few countries imple-ment control efforts and there are few data on the impact of the disease to support policy decisions. We conducted a survey to determine the impact of tungiasis among primary school children across nine counties of Kenya. A total of 10,600 pupils aged 8 to 14 years were randomly selected from 97 primary schools and examined for tungiasis. For …

Chelation Enables Selectivity Control In Enantioconvergent Suzuki-Miyaura Cross-Couplings On Acyclic Allylic Systems, Violeta Stojalnikova, Stephen J Webster, Ke Liu, Stephen P Fletcher

Faculty, Staff and Student Publications

Asymmetric Suzuki-Miyaura cross-couplings with aryl boronic acids and allylic electrophiles are a powerful method to convert racemic mixtures into enantioenriched products. Currently, enantioconvergent allylic arylations are limited to substrates that are symmetrical about the allylic unit, and the absence of strategies to control regio-, E/Z- and enantioselectivity in acyclic allylic systems is a major restriction. Here, using a system capable of either conjugate addition or allylic arylation, we have discovered the structural features and experimental conditions that allow an acyclic system to undergo chemo- and regioselective, enantioconvergent allylic Suzuki-Miyaura-type arylation. A wide variety of boronic acid coupling partners can be …

More Than A Monolith: Three Essays On The Diverse Journey Of Immigrant Students And Their Postsecondary Outcomes, Rian Rinaldi Djita

Graduate Theses and Dissertations

For many years, the United States (U.S.) has been the country with the largest number of immigrants. As a result, policy about immigrant students’ success becomes crucial since it carries not only ethical implications but also economic and societal implications. While there have been other alternatives for students’ success, such as Career and Technical Education (CTE), undeniably, college is still seen as a common pathway to success (e.g., Choi, 2015; Heckman et al., 2018; Turner, 2004). Unfortunately, there are several gaps in the literature on immigrant students’ success and postsecondary outcomes. First, while there is an increasing number of immigrants …

Exploring The Potential Of Electromagnetic-Driven Energy Technologies In Preventing Microbial And Aflatoxin Contamination Of Grains, Abass A. Oduola

Graduate Theses and Dissertations

Electromagnetic-driven energy such as infrared (IR) technology holds great potential in deactivating Aspergillus flavus spores and prevents aflatoxin B1 (AFB1) contamination. Aflatoxins, highly toxic secondary metabolites primarily produced by Aspergillus species within the Flavi section (A. flavus, A. parasiticus, and A. nomius), pose substantial health risks to both humans and animals due to their significant toxicity and carcinogenic properties. Detecting and quantifying the presence and proliferation of these harmful fungi on food materials can be achieved by measuring the concentration of ergosterol. Ergosterol is a sterol compound produced in the cell membranes of fungi during their growth, providing …

The Expression Of Recombinant Cas9 Proteins In E. Coli Bl21(De3) Strains, Morgan Reese

Graduate Theses and Dissertations

Abstract Extensively used for genome editing, CRISPR-Cas9 is a relatively new tool that has made a major impact in the genomic engineering landscape. Due to this, the production of CRISPR proteins that are not commercially available can limit research applications. Here, we present methods for optimizing laboratory scale production of CRISPR proteins including Cas9. The method uses IPTG to induce gene expression of the specified Cas9 and nickel column purification to isolate proteins. CRISPR proteins are validated for purity by SDS-PAGE gel, western blot, and for activity by in vitro digestion. We thoroughly validate and compare the effectiveness of BL21(DE3) …

Production And Heat Unit Accumulation Tracking Of Long-Cane Blackberry In Controlled Environments, Leala Machesney

Graduate Theses and Dissertations

Consumer demand for locally produced and high-quality blackberries is projected to increase. Most blackberry production is field-based, however, there is interest in producing blackberries using soilless culture and “long-cane” technique, where plants are grown in containers and trellised vertically. Soilless “long-cane” production of blackberries is viewed as a possible solution to the yield losses caused by soilborne pathogens such as Fusarium oxysporum, and methods of soil-borne pathogen control have become increasingly difficult with the ban of methyl bromide, a highly effective and widely used but environmentally harmful soil fumigant. Other reported benefits of soilless caneberry production include greater yields, increased …

Temporal Trends And Dental Metric Variation In The Macaca Sylvanus Lineage, Cristina Stan

Graduate Theses and Dissertations

The extensive collection of fossil macaques from Europe, spanning from the Late Miocene to the Late Pleistocene period, is believed to be of the species Macaca sylvanus. However, there has been a prolonged discussion regarding the classification of these specimens into a single taxonomic group as the existing dental sample exhibits a large amount of morphological and metric variation. Specifically, researchers have attempted to identify multiple subspecies based on chronological data of the paleontological locality and, secondly, based on dental metric variation. In this study, I assess temporal trends in the fossil record of Macaca sylvanus and compare overall variation …

Study design: Follow-up study of patients who completed glucose tolerance testing 5 to 10 years after enrollment in a mild gestational diabetes mellitus (GDM) treatment trial or concurrent non-GDM cohort. Maternal serum insulin concentrations and cardiovascular markers VCAM-1, VEGF, CD40L, GDF-15, and ST-2 were measured, and insulinogenic index (IGI, pancreatic β-cell function) and 1/ homeostatic model assessment (insulin resistance) were calculated. Biomarkers were compared by presence of HDP (gestational hypertension or preeclampsia) during pregnancy. Multivariable linear regression estimated the …

Is Routine Use Of External Spinal Orthoses Necessary After Operative Stabilization Of Cervical Spine Injuries?, Derek Moody, James Showery, Ran Lador, Isaac Hernandez, Mark L Prasarn

Faculty, Staff and Student Publications

Study design: Retrospective Review.

Objective: The purpose of this study is to evaluate the efficacy of postoperative cervical orthoses to prevent fixation failure and loss of reduction after operative treatment of cervical spine fractures.

Summary of background data: While cervical orthoses are most times tolerated in trauma patients, it is not clear that postoperative bracing is effective at reducing the rate of fixation failure or nonunion in this patient population. Cervical collars may delay rehabilitation, increase the risk of dysphagia and aspiration, and can contribute to skin breakdown.

Methods: All patients who underwent operative stabilization for cervical spine injuries at …

Dynamics Of Karyotype Evolution, Elena Kuzmin, Toby M Baker, Peter Van Loo, Leon Glass

Faculty, Staff and Student Publications

In the evolution of species, the karyotype changes with a timescale of tens to hundreds of thousand years. In the development of cancer, the karyotype often is modified in cancerous cells over the lifetime of an individual. Characterizing these changes and understanding the mechanisms leading to them has been of interest in a broad range of disciplines including evolution, cytogenetics, and cancer genetics. A central issue relates to the relative roles of random vs deterministic mechanisms in shaping the changes. Although it is possible that all changes result from random events followed by selection, many results point to other non-random …

Pet Imaging Of Metabolism, Perfusion, And Hypoxia: Fdg And Beyond, Austin R Pantel, Seong-Woo Bae, Elizabeth J Li, Sophia R O'Brien, H Charles Manning

Faculty, Staff and Student Publications

Imaging glucose metabolism with [18F]fluorodeoxyglucose positron emission tomography has transformed the diagnostic and treatment algorithms of numerous malignancies in clinical practice. The cancer phenotype, though, extends beyond dysregulation of this single pathway. Reprogramming of other pathways of metabolism, as well as altered perfusion and hypoxia, also typifies malignancy. These features provide other opportunities for imaging that have been developed and advanced into humans. In this review, we discuss imaging metabolism, perfusion, and hypoxia in cancer, focusing on the underlying biology to provide context. We conclude by highlighting the ability to image multiple facets of biology to better characterize cancer and …

On The Optimal Diagnosis And The Evolving Role Of Pimavanserin In Parkinson's Disease Psychosis, Fernando L Pagan, Paul E Schulz, Yasar Torres-Yaghi, Gregory M Pontone

Faculty, Staff and Student Publications

Parkinson's disease (PD) is associated with the development of psychosis (PDP), including hallucinations and delusions, in more than half of the patient population. Optimal PD management must therefore involve considerations about both motor and non-motor symptoms. Often, clinicians fail to diagnosis psychosis in patients with PD and, when it is recognized, treat it suboptimally, despite the availability of multiple interventions. In this paper, we provide a summary of the current guidelines and clinical evidence for treating PDP with antipsychotics. We also provide recommendations for diagnosis and follow-up. Finally, an updated treatment algorithm for PDP that incorporates the use of pimavanserin, …
