Deficit Irrigation Management For Irrigated Corn In Nebraska: Economically Viable?, Lia Nogueira, Cory Walters, Emily O'Donnell, E. Wesley F. Peterson, Suat Irmak

Cornhusker Economics

In this study we determine the economic value of deficit irrigation management using both technological and methodological advancements. The use of soil moisture probes represents the technological improvement. We provide improvements in the methodology as follows. Regarding data, we employ a field-size study, instead of plots, where the irrigation decision is determined by the moisture level in the soil measured through a soil moisture probe. Regarding the understanding of the yield response to water, although we examine the commonly used quadratic function, we improve upon this specification by also examining an alternative response function, the linear response stochastic plateau. Our …

Healthcare Service Use, Help-Seeking Behaviors, And Health And Wellbeing In Attenuated Psychosis, Jasmine Ranjbari-Sisan, William D. Spaulding, Tierney K. Lorenz

Honors Program: Senior Projects (Public)

Persons with serious mental illness (SMI) receive poorer-than-standard healthcare, contributing to a 20-year reduction in the average life expectancy of persons with SMI. While extant literature describes the health disparities experienced by persons with SMI, little research examines the relationship between attenuated psychotic symptoms, healthcare service use, and help-seeking behaviors that may contribute to the disparities in this vulnerable population. This study explores the relationships between attenuated psychotic symptoms, physical health symptoms and related distress, healthcare service use, and help-seeking intentions to better understand health disparities in vulnerable and marginalized populations, such as individuals with SMI.

Dealing With “Humanewashing” Claims: Vital Farms’ Crucial Next Step, Bryce Janke, Cole Johnson, Kieran Mcwilliams, Justin Morrow, Isabelle Schmidt

B-Corp Case Studies by UNL Raikes Seniors

Vital Farms prides itself in their ethical and environmentally-friendly production of pasture-raised eggs, butter, and ghee. A popular tagline for the company is “keeping it bullsh*t-free.” This is core to their company mission and values. However, they are currently facing a PETA class action lawsuit for potential humanewashing and greenwashing, essentially false advertising. So, what happens when the Certified B-Corporation is under attack for the very thing that sets it apart from its competition? Is it possible to rebuild trust with the public and regain ethical standing after bad PR? What are humanewashing and greenwashing, and is Vital Farms guilty?

Blurred Lines: An Analysis Of Karel Husa's Music For Prague, 1968 Using Fuzzy Serialism, Sydney Wilson

Glenn Korff School of Music: Dissertations, Theses, Student Creative Work, and Performances

The wind band work Music for Prague, 1968 by Karel Husa is a well-respected work that has withstood the test of time. Husa, a native of then-Czechoslovakia, composed the piece in less than a year from the United States. The piece serves as a method of expressing his feelings regarding the invasion of his homeland where his family was still residing. Husa accomplished this expression through the use of a nationalistic theme, the Hussite War Song, and his own integration of twelve-tone serialism.

This study looks at pre-existing literature surrounding Husa’s use of serialism, including an analysis by Husa himself. …

Managing Programmatic Trade-Offs For Centers Of Teaching And Learning: Applying A Segmentation, Targeting, And Positioning Approach To Pedagogical Offerings, Christopher Vicente Hsin-Hung S. Chen, Ian G. Althouse, Caitlin P. Declercq, Mark L. Phillipson

To Improve the Academy: A Journal of Educational Development

The demands of current instructional realities for moving to completely online formats have led to dramatic changes in the ways that centers for teaching and learning serve their communities. Pedagogical programs have been adapted, invented, and reimagined for online modalities. In this article, we share an approach borrowed from marketing—segmentation, targeting, and positioning (STP)—and describe three cases showing the application of STP in our center’s work with instructors. This approach has helped us clarify and target our pedagogical priorities, allowing us to make appropriate trade-offs to produce more focused educational development programming that better meets our audience’s needs, constraints, and …

Wakara's Waterscapes: Storytelling, Cartography, And Rhetorical Sovereignty On The Shores Of The Green River, Abbey O'Brien

Honors Program: Senior Projects (Public)

In the mid nineteenth-century, Wakara, a prominent Ute leader, witnessed the invasion of his homeland by Mormon settlers and mountain-men. He met the scouts and explorers who were sent out to examine the land and waterscapes, and who drew maps along their way. It was those same maps which were eventually used as tools to justify colonial expansion all across the Utah territories, Wakara’s home. But Wakara resisted. Employing his understandings of the roles that cartography and the written word played in Mormon and settler discourse, Wakara created his own maps in order to assert his Indigenous authority over the …

Diffractive Imaging Of Laser Induced Molecular Reactions With Kiloelectron–Volt Ultrafast Electron Diffraction, Yanwei Xiong

Department of Physics and Astronomy: Dissertations, Theses, and Student Research

Capturing the structural changes during a molecular reaction with ultrafast electron diffraction (UED) requires a high spatiotemporal resolution and sufficiently high signal-to-noise to record the signals with high fidelity. In this dissertation, I have focused on the development of a tabletop gas phase keV-UED setup with a femtosecond temporal resolution. A DC electron gun was employed to generate electron pulses with a high repetition rate of 5 kHz. The space charge effect in the electron pulse was ameliorated by compressing the 90 keV electron pulse longitudinally with a time varying electric field in an RF cavity. The velocity mismatch between …

Three Thingness: A Critical Introduction To The Collection, Kasey Peters

Department of English: Dissertations, Theses, and Student Research

The following project, "Three Thingness," consists of a critical introduction and craft essay on short story writing, and a sample of the collection Very Light in the End. The critical essay "Three Thingness" introduces a framework for evaluating short stories, and then evaluates a few key components undergirding the collection: gender, plot, and comic relief. Part postmodern realism and part absurst-lite^tm fiction, the collected stories depict characters as they navigate prescriptive narratives about bodies, gender, queerness, and illness.

Simple Darwin Core For Non-Biologists Primer, Megan N. O'Donnell, Leslie M. Delserone

University of Nebraska-Lincoln Libraries: Faculty Publications

This primer focuses on Simple DwC (http://rs.tdwg.org/dwc/terms/simple/), a “mechanism used to share biodiversity information using the simplest methods and structure” (Darwin Core Task Group, 2014). With Simple DwC, the DwC schema is applied to a single flat file (i.e., table or spreadsheet). Because it is a self-contained data set that can be opened, edited, and analyzed using a wide variety of software, Simple DwC is easier to implement than other forms of DwC that use XML, RDF, or relational databases. The primer’s goal is to assist a curator presented with a data set structured in Simple DwC, or …

Deep Reinforcement Learning For Articulatory Synthesis In A Vowel-To-Vowel Imitation Task, Denis Shitov, Elena Pirogova, Tadeusz A. Wysocki, Margaret Lech

Department of Electrical and Computer Engineering: Faculty Publications

Articulatory synthesis is one of the approaches used for modeling human speech production. In this study, we propose a model-based algorithm for learning the policy to control the vocal tract of the articulatory synthesizer in a vowel-to-vowel imitation task. Our method does not require external training data, since the policy is learned through interactions with the vocal tract model. To improve the sample efficiency of the learning, we trained the model of speech production dynamics simultaneously with the policy. The policy was trained in a supervised way using predictions of the model of speech production dynamics. To stabilize the training, …

Fresh Produce As A Potential Vector And Reservoir For Human Bacterial Pathogens: Revealing The Ambiguity Of Interaction And Transmission, Ahmed Esmael, Rashad R. Al-Hindi, Raed S. Albiheyri, Mona G. Alharbi, Amani A. R. Filimban, Mazen S. Alseghayer, Abdulaziz M. Almaneea, Meshari Ahmed Alhadlaq, Jumaa Ayubu, Addisu D. Teklemariam

Nebraska Center for Virology: Faculty Publications

The consumer demand for fresh produce (vegetables and fruits) has considerably increased since the 1980s for more nutritious foods and healthier life practices, particularly in developed countries. Currently, several foodborne outbreaks have been linked to fresh produce. The global rise in fresh produce associated with human infections may be due to the use of wastewater or any contaminated water for the cultivation of fruits and vegetables, the firm attachment of the foodborne pathogens on the plant surface, and the internalization of these agents deep inside the tissue of the plant, poor disinfection practices and human consumption of raw fresh produce. …

Genome Assembly Of The Brassicaceae Diploid Orychophragmus Violaceus Reveals Complex Whole-Genome Duplication And Evolution Of Dihydroxy Fatty Acid Metabolism, Fan Huang, Peng Chen, Xinyu Tang, Ting Zhong, Taihua Yang, Chinedu Charles Nwafor, Chao Yang, Xianhong Ge, Hong An, Zaiyun Li, Edgar B. Cahoon, Chunyu Zhang

Center for Plant Science Innovation: Faculty Publications

Orychophragmus violaceus is a Brassicaceae species widely cultivated in China, particularly as a winter cover crop in northern China because of its low-temperature tolerance and low water demand. Recently, O. violaceus has also been cultivated as a potential industrial oilseed crop because of its abundant 24- carbon dihydroxy fatty acids (diOH-FAs), which contribute to superior high-temperature lubricant properties. In this study, we performed de novo assembly of the O. violaceus genome. Whole-genome synteny analysis of the genomes of its relatives demonstrated that O. violaceus is a diploid that has undergone an extra whole-genome duplication (WGD) after the Brassicaceae-specific α-WGD event, …

Inherent Envelope Fluctuations In Forward Masking: Effects Of Age And Hearing Loss, Marc A. Brennan, Adam Svec, Afagh Farhadi, Braden N. Maxwell, Laurel H. Carney

Department of Special Education and Communication Disorders: Faculty Publications

Forward masking is generally greater for Gaussian noise (GN) than for low-fluctuation noise maskers, i.e., GN disruption. Because the minimal hearing loss that is associated with older age may affect GN disruption differently than more significant hearing loss, the current study explored the contribution of minimal hearing loss associated with older age to GN disruption. GN disruption was measured using three masker-signal delays (25, 75, and 150 ms) for three adult groups: younger participants with normal hearing (NH), older participants with minimal hearing loss, and older participants with sensorineural hearing loss. The role of underlying mechanisms was tested using a …

Perspectives On Adaptive Functioning And Intellectual Functioning Measures For Intellectual Disabilities Behavioral Research, Laura J. Mattie, Susan J. Loveall, Marie Moore Channell, Derek B. Rodgers

Department of Special Education and Communication Disorders: Faculty Publications

Introduction: Intellectual disability (ID) is a significant limitation in both intellectual ability and adaptive functioning, but many studies of participants with ID only include a measure of overall intellectual functioning when describing their samples. The purpose of this perspective article was to provide a starting point for future research regarding the utility of including measures of both intellectual and adaptive functioning in research focused on ID. In this article, we discuss the differences and similarities between the constructs of intellectual and adaptive functioning, how they are measured, and the benefits of using both measures to describe participant abilities. Data …

High-Risk Sexual Behavior In Nebraska Adolescents; History, Risk Factors, And Mediation, Kiya Hudson

Honors Program: Senior Projects (Public)

High-risk sexual behavior is a public health crisis that impacts adolescents at staggering rates. In Nebraska, rates of sexually transmitted infection (STI) and sexually transmitted disease (STD) cases have been on the rise over the last four years. The problem this paper addresses is the need to fill in the gaps in knowledge surrounding high-risk sexual behavior in Nebraska adolescents. It is important to address these gaps in knowledge because currently, we are failing our adolescents when it comes to providing them with all of the necessary skills, information, and tools to lead a healthy life. When we know how …

An Evidence-Based Design, Translation, And Implementation Of A Hypertension Health Education Pamphlet, Katie Patton

Honors Program: Senior Projects (Public)

Health equity is the opportunity for all to attain their highest level of health. This includes creating understandable educational resources that aid in reducing risk and controlling symptoms of disease. A singular piece of written education material will not be effective among all in a broad population due to the many different backgrounds in which people originate. While this may seem obvious, there is a wide gap between knowledge and action. This gap leads to health disparities, or differences in health status between people that are related to social or demographic factors such as race, gender, income, or geographic region …

Facilitating Transformative Innovations In Sustainability Education [Version 2], Martin Melin, Geir Lieblein, Tor Arvid Breland, Charles A. Francis

Department of Agronomy and Horticulture: Faculty Publications

Educational strategies globally are changing from an authoritative, top-down model to one focused on greater student and stakeholder participation in planning and implementation of research and educational activities. In addition to emphasis on student-centered education, strategies currently evolve to encompass learning organizations and multistakeholder learning networks. These are essential to address the complexity and scope of tomorrow’s challenges, involving issues that could be called ’wicked problems’ not easily addressed by single disciplines nor resulting in solutions that please all the players. In this study we describe how a transformative innovation – the NEXTFOOD educational approach – may contribute substantially to …

Systematic Review Of Reflection Spectroscopy-Based Skin Carotenoid Assessment In Children, Saima Hasnin, Dipti Dev, Taren Swindle, Susan B. Sisson, Stephanie Jilcott Pitts, Tirna Purkait, Shari C. Clifton, Jocelyn Dixon, Virginia C. Stage

Department of Child, Youth, and Family Studies: Faculty Publications

Assessing children’s skin carotenoid score (SCS) using reflection spectroscopy (RS) is a non-invasive, widely used method to approximate fruit and vegetable consumption (FVC). The aims for the current review were to (1) identify distributions of SCS across demographic groups, (2) identify potential non-dietary correlates for RS-based SCS, (3) summarize the validity and reliability of RSbased SCS assessment, and (4) conduct meta-analyses of studies examining the correlation between RS-based SCS with FVC. A literature search in eight databases in June 2021 resulted in 4880 citations and peer-reviewed publications written in English that investigated children’s (2–10 years old) SCS using RS. We …

Honors Program: Senior Projects (Public)

The goal of this Honors Thesis was to explore French superstitions and idioms through a fictional story. To facilitate the inclusion of a range of sayings and superstitious beliefs, the short story “Jamais Deux Sans Trois” is a borderline paranormal piece of fiction which is meant to call into question how the reader interprets the world. The story, written in French, revolves around a pair of best friends and their experiences with a series of events which may or may not be explained through the lens of superstitions, depending on which character is asked at which point in the story. …

Predicting Mobility Using Limited Data During Early Stages Of A Pandemic, Michael T. Lash, S. Sajeesh, Özgür M. Araz

Department of Marketing: Faculty Publications

The COVID-19 pandemic has changed consumer behavior substantially. In this study, we explore the drivers of consumer mobility in several metropolitan areas in the United States under the perceived risks of COVID-19. We capture multiple dimensions of perceived risk using local and national cases and death counts of COVID-19, along with real-time Google Trends data for personal protective equipment (PPE). While Google Trends data are popular inputs in many studies, the risk of multicollinearity escalates with the addition of more relevant terms. Therefore, multicollinearity-alleviating methods are needed to appropriately leverage information provided by Google Trends data. We develop and utilize …
