Cognitive Interviewing Within A Mixed Methods Practice: Utilization And Methodological Exploration Of Cognitive Interviewing, Jack Riley Hebner

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Cognitive interviewing (CI) is a memory-enhancing technique used to extract more valid data from participants by addressing cognitive needs. Present research applied CI to program evaluation, theorizing that more quality data would be retrieved, especially when utilizing a mixed methods approach. The program chosen to further explore this technique and provide potentially invaluable evaluation data was the Educational Psychology Department at the University of Nebraska-Lincoln (EDPS). The sample consisted of 32 individuals, consisting of graduate students and faculty across all programs.

The overall evaluation focused on inter-program and inner program understanding which is operationalized as the ability to relay how …

Understanding And Intervening In Children's Tick Risk Perceptions And Protective Behaviors: A Grounded Theory, Ariel Dawdy

Department of Entomology: Dissertations, Theses, and Student Research

Children, ages 8 years and younger, are at a particularly high risk of contracting a tick-borne disease. This is partially due to the misconceptions spread about tick protective behavior and a poor understanding of how antibiotic treatment can help. Because most communities and families believe that tick control is the individual’s responsibility, looking at the interaction between ticks and human children is essential to understanding the individual’s motivations to protect themselves. To help alleviate the number of individuals contracting tick-borne diseases, misconceptions must be addressed, intervention programs implemented, and a behavioral change must occur. This study used a qualitative research …

Morality, Outgroups, And Politics, John Jostes

Department of Political Science: Dissertations, Theses, and Student Research

Moral differences between Democrats and Republicans contribute to affective polarization, or how negatively each side feels toward one another. Partisans are also generally aware of and sensitive to which social groups comprise the other political party. The present study examines if changes to the United States population, and thus levels of support for the two parties, will influence affective polarization. To do so, participants were randomly assigned to one of two treatment conditions in which they read about demographic changes reported in the 2020 U.S. Census, or a control condition. I find that the treatment conditions did not have a …

Soybean Cyst Nematode (Heterodera Glycines Ichinohe) Virulence Assay Against Resistance Sources In Nebraska, Pratibha Karki

Department of Plant Pathology: Dissertations, Theses, and Student Research

Soybean cyst nematode (SCN, Heterodera glycines Ichinohe), one of the major yield-limiting pathogens of soybean, is currently found in 60 counties of Nebraska that produce more than 90% of the state’s soybean. Often, yield loss occurs without any above-ground symptoms, which makes it difficult to manage. The primary management option is the use of SCN-resistant varieties. Several soybean plant introductions serve as resistance sources against SCN. Unfortunately, the single source, PI 88788, is used in approximately 90% of resistant varieties and its prolonged use has increased the virulence status of SCN in the U.S. A study was conducted to assess …

Analysis Of Impulsive Differential Equation Models Of Cell Populations Undergoing Radiation Therapy, Abigail D'Ovidio Long

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

Radiation therapy is a mode of treatment which is implemented for approximately 50% of cancer patients. Treatment needs to be able to kill cancer cells, but also do minimal damage to surrounding healthy tissue. We propose two main impulsive differential equation models of radiation therapy to capture the periodic nature of the treatment. These models build off of previous studies using clinical data to ensure biological relevance. The first model incorporates only cancer cell populations, and we provide parameter relationships which theoretically ensure treatment outcomes of cancer eradication, cancer approaching a carrying capacity, and cancer approaching a periodic solution. We …

The Impact Of Tier 1 Pbis Implementation Fidelity On Education Outcomes For Students With Attention-Deficit/Hyperactivity Disorder, Rebecca Anne (Wright) Overfield

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

This dissertation study aimed to examine the relationship between Tier 1 Positive Behavioral Intervention and Supports (PBIS) implementation fidelity and the academic (e.g., MAP Growth scores) and behavioral outcomes (e.g., major office discipline referrals, suspensions). High quality PBIS implementation fidelity has been linked with improved standardized test scores and decreased instances of major office discipline referrals, in-school suspensions, and out-of-school suspensions for students with and without behavioral difficulties. However, no research has been done on the impact of PBIS implementation fidelity on students with ADHD. It is estimated that at least 40% of students with ADHD require at least one …

Novel Mouse Models To Study The Role Of T Cells In Cardiac Autoimmunity, Meghna Sur

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

Myocarditis patients can chronically develop dilated cardiomyopathy and autoreactive T cells could contribute to the disease pathogenesis, but defining their antigen specificity remains a major challenge. To fill this gap, we generated T cell receptor (TCR) transgenic (Tg) mice specific to cardiac myosin heavy chain (Myhc)-α 334–352 and made a few observations. First, we unexpectedly noted both CD4 and CD8 T cells expressing TCRs specific to Myhc-α 334–352. Second, while Tg T cells from myocarditis-resistant C57BL/6J mice did not respond to Myhc-α 334–352, those from immunized mice responded, indicating that in vivo priming is necessary to break tolerance. Third, upon …

Spatial Ecology Of American Bison On Vermejo Park Ranch, New Mexico, Kate Ann Asmus

School of Natural Resources: Dissertations, Theses, and Student Research

American bison (Bison bison) are a keystone species that impact grassland productivity, plant diversity, and landscape heterogeneity. We used GPS telemetry and a replicate herbivore grazing experiment on Vermejo Park Ranch in northeastern New Mexico to advance understanding of bison spatial ecology and grazing dynamics. First, we evaluated the potentially disparate influences of forage productivity and site fidelity on the size and selection of home ranges of bison. Home range size was strongly negatively influenced by forage productivity. However, home range selection was influenced more strongly by site fidelity than spatial variation in forage, as bison selected home …

Vale Strategic Audit, Nikolas Mancio

Honors Program: Senior Projects (Public)

The Chinese government is critical in shaping the global mining and metals industry, specifically for companies like Vale S.A., the world’s largest iron ore and nickel producer. China’s dominance as the largest importer of iron ore significantly impacts commodity prices and demand, with its government exerting substantial influence through production quotas, infrastructure spending, and environmental regulations. Vale’s strategic position in the Chinese market is a cornerstone of its operations. It is supported by investments in distribution centers, blending facilities, and high-grade iron ore that align with China’s environmental goals. However, this reliance also makes Vale vulnerable to shifts in Chinese …

Regulating Robo-Advisors In An Age Of Generative Artificial Intelligence, Daniel Schwarcz, Tom Baker

Law & Economics Working Papers

New generative Artificial Intelligence (AI) tools can increasingly engage in personalized, sustained and natural conversations with users. This technology has the capacity to reshape the financial services industry, making customized expert financial advice broadly available to consumers. However, AI’s ability to convincingly mimic human financial advisors also creates significant risks of large-scale financial misconduct. Which of these possibilities becomes reality will depend largely on the legal and regulatory rules governing “robo-advisors” that supply fully automated financial advice to consumers. This Article consequently critically examines this evolving regulatory landscape, arguing that current U.S. rules fail to adequately limit the risk that …

Tackling Fall Risk In Geriatric Dementia Patients: The Impact Of Medication Reconciliation Relating To Polypharmacy & Falls, Jenl Khristen Ang

Nursing | Student Research Posters

Over half of the elderly population are taking three or more prescription drugs daily. For those aged 65 and older, polypharmacy, taking five or more medications, is common due to conditions like hypertension, heart disease, arthritis, and diabetes (CDC, 2019). Managing these medications can be challenging, especially for those with dementia, who may also take drugs for conditions such as diabetes or depression, which can worsen cognitive impairment (Chippa & Roy, 2023). The complex regimens and increased sensitivity to medications heighten the risk of adverse events, particularly falls, a major cause of injury, hospitalizations, and loss of independence in older …

Engineer-Friendly Synergetic Methodology For Surrogate Modeling Of Complex Connections By Modal-Based Low-Fidelity Finite Element Model Updating Approach, Milad Mehrkash

Doctoral Dissertations

Finite element models are widely used to simulate the behavior of structures. They can also be utilized for structural condition assessment and health monitoring. However, due to software limitations, simplifying assumptions, and lack of knowledge about the system properties, the predictions of the numerical models may deviate from laboratory or field measurements of the actual structure. This issue may be further exacerbated by the simplifications applied in modeling complex connections, which is a common practice in numerical modeling to save time and effort. While finite element model updating improves the accuracy of numerical models, physics-based surrogate modeling of connections balances …

Functional Characterization Of Copper Tolerance In The Atypical Microsymbiont Pseudofrankia Inefficax, Megan Paige Garcia

Doctoral Dissertations

Bacterial species in the family Frankiaceae are soil-dwelling microsymbionts that form a mutualistic symbiosis, termed the actinorhizal symbiosis, with over 220 species of woody dicots. In this relationship, frankia fix atmospheric nitrogen to ammonia, a form usable by plants, while the bacteria benefit from the carbon sources exuded by their actinorhizal hosts. Since nitrogen is typically a limiting nutrient for growth in degraded and contaminated soils, actinorhizal plants establish at these sites as pioneer plant species, initiating a path for phytoremediation. Likely due to their association with plant hosts in contaminated soils, most frankia strains have evolved above average tolerances …

Improving Understanding Of Fluvial Reach-Scale Solute Transport And Uptake Using A Particle Tracking Model And Random Forest Machine Learning Model, Jiaying Liu

Doctoral Dissertations

In addition to transporting flowing water, river systems carry dissolved nutrients and pollutants, which can experience chemical reactions, biological uptake, or retention in surface or hyporheic zones. This dissertation enhances our understanding of solute transport and uptake in river reaches through three main components. The first component involves the development of a novel curve-fitting model designed to capture the characteristics of pulse-release breakthrough curves (BTCs) from tracer studies with conservative solutes.

Georgia’S Law Of Rules: Textualism And A Survey Of The Canons, Matthew P. Cavedon

Mercer Law Review

Before a travel guide can be written, there has to be a map; before treatises can be written, there have to be surveys. This Article is a survey of Georgia textualism and every canon the Supreme Court of Georgia has recognized in its 180-year history. I begin with a general overview of textualism: the priority of plain meaning, legal context, and legal history (Part I). If there is no ambiguity, “our search for [legal] meaning is at an end.”

But of course, this frequently fails to be the case, so I have read nearly 4,000 cases in search of the …

The Endocrine And Body Composition Responses To Accentuated Eccentric Loading Performed In Cluster Sets During A Strength–Endurance Training Block, Kurt W. Mcdowell, Alex Long, Daniel Gahreman, D. Andrew Nelson, Nicholas J. Goode, Ryan P. Lis, Sungwon Chae, Satoshi Mizuguchi, Marten Baur, Kevin F. Breuel, Marco Duca, John P. Wagle, Andy C. Fry, Michael H. Stone

Kinesiology

Featured Application: Research on the endocrine changes from AEL training is limited, especially for long-term effects. This study suggests that combining AEL with CS might offer similar or slightly better results compared to traditional training. However, the practical challenges, such as increased training monotony and strain, may outweigh the minimal benefits. The extra cost, time, and effort required for AEL, especially in large team settings, might not be justified. Additionally, individual differences in optimal loading prescriptions could complicate its use, making traditional methods more efficient. This study investigated the endocrine responses to accentuated eccentric loading (AEL) paired with cluster sets …
