Department of Educational Psychology: Faculty Publications

Background: Communication is a critical component of the patient-provider relationship; however, limited research exists on the role of nonverbal communication. Virtual human training is an informatics-based educational strategy that offers various benefits in communication skill training directed at providers. Recent informatics-based interventions aimed at improving communication have mainly focused on verbal communication, yet research is needed to better understand how virtual humans can improve verbal and nonverbal communication and further elucidate the patient-provider dyad.

Objective: The purpose of this study is to enhance a conceptual model that incorporates technology to examine verbal and nonverbal components of communication and develop a …

Increased Liver Stiffness Promotes Hepatitis B Progression By Impairing Innate Immunity In Ccl4-Induced Fibrotic Hbv+ Transgenic Mice, Grace Bybee, Youra Moeun, Weimin Wang, Kusum K. Kharbanda, Larisa Y. Poluektova, Srivatsan Kidambi, Natalia A. Osna, Murali Ganesan

Department of Chemical and Biomolecular Engineering: Faculty Publications

Background: Hepatitis B virus (HBV) infection develops as an acute or chronic liver disease, which progresses from steatosis, hepatitis, and fibrosis to end-stage liver diseases such as cirrhosis and hepatocellular carcinoma (HCC). An increased stromal stiffness accompanies fibrosis in chronic liver diseases and is considered a strong predictor for disease progression. The goal of this study was to establish the mechanisms by which enhanced liver stiffness regulates HBV infectivity in the fibrotic liver tissue. Methods: For in vitro studies, HBV-transfected HepG2.2.15 cells were cultured on polydimethylsiloxane gels coated by polyelectrolyte multilayer films of 2 kPa (soft) or 24 kPa (stiff) …

Applications Of Diversity Language To Descriptions Of Collection Development Activities At Academic Libraries: An Exploratory Analysis Of Strategic Plans And Diversity Information Webpages, David Macaulay

University of Nebraska-Lincoln Libraries: Faculty Publications

Diversity is commonly invoked as a goal for libraries in a variety of domains, including collections. This study explores how diversity language is used to characterize collection development efforts at a sample of large North American academic libraries, through content analysis of strategic planning documents as well as library webpages providing information about diversity efforts. The topic of collection diversity was found to be not consistently addressed in these documents. While 90% of the institutions whose strategic plans were examined mentioned diversity in some way, less than half of these did so in relation to collections; about one-third of the …

The ‘Hijacking’ Of The Scandinavian Journal Of Information Systems: Implications For The Information Systems Community [Opinion], Sune Dueholm Müller, Johan Ivar Sæbø

Copyright, Fair Use, Scholarly Communication, etc.

Journal hijacking, which refers to the attempted brand takeover of a journal by a third party, is a nascent threat confronting the information systems (IS) community, as evidenced by cybercriminals having established an online presence, masquerading as the Scandinavian Journal of Information Systems (SJIS). The SJIS hijacking damages the journal's reputation, leads to payment and publication scams, involves identity theft among unsuspecting IS researchers, and results in tarnished author reputations. Beyond SJIS, journal hijacking presents a threat, not only to the IS community, but also to science and academic integrity in general if researchers and readers cannot distinguish between fake …

Indigenous Peoples' right to sovereignty forms the foundation for advocacy and actions toward greater Indigenous self-determination and control across a range of domains that impact Indigenous Peoples' communities and cultures. Declarations for sovereignty are rising throughout Indigenous communities and across diverse fields, including Network Sovereignty, Food Sovereignty, Energy Sovereignty, and Data Sovereignty. Indigenous Research Sovereignty draws in the sovereignty discourse of these initiatives to consider their applications to the broader research ecosystem. Our exploration of Indigenous Research Sovereignty, or Indigenous self-determination in the context of research activities, has been focused on the relationship between Indigenous Data Sovereignty and efforts to …

Correction To: Genetic Characterization And Expression Analysis Of Wheat (Triticum Aestivum) Line 07or1074 Exhibiting Very Low Polyphenol Oxidase (Ppo) Activity, S. M. Hystad, J. M. Martin, R. A. Graybosch, M. J. Giroux

Department of Agronomy and Horticulture: Faculty Publications

The above mentioned article was published in 2015 with an error in the naming of one of the allele sequences for the PPO gene on the D genome. The PPO-D1f allele was incorrectly named as it is identical to the PPO-D1c allele previously published in GenBank by the authors on March 11th, 2014. An alignment between the previously published PPOD1c allele and a resequencing of the parental line 07OR1074 shows that the PPO-D1f allele is identical to the PPO-D1c allele. The allele in the paper referred to as PPO-D1f should be treated as PPO-D1c and can be accessed at NCBI …

Inamasu, Lúcio A. De C. Jorge, Ladislau M. Rabello, Ivani De O.N. Lopes, Sérgio Das Chagas, Jefferson L.R. De Souza, Márcio De Souza, Amandio Pires, James Schepers

Department of Agronomy and Horticulture: Faculty Publications

Variable-rate application has great potential to reduce variability and increase yield by spatially optimizing agricultural inputs. In cotton, plant growth regulators (PGRs) control excessive growth and provide suitable plant height for harvest operations. This study evaluates the effect of variable-rate PGR application compared to constant-rate application to reduce yield spatial variability and increase yield. The variable-rate approach was carried out in 2020 based on zonal applications defined by clustering analysis using soil electrical conductivity, vegetation indexes, and yield maps. Application doses and timings were determined by integrating plant height measurements for the whole field in 2019 and by zone in …

Teaching Agroecology: Preparing Students For Navigating Uncharted Territory, Charles A. Francis, Steve Gliessman

Agroecologists understand that farming and food systems are more complex than the aggregation of their components. This realization drives our choices of learning strategies and activities that will prepare students for complexity and uncertainty. Our quest for a just, sustainable, and nutritious food system adequate to equitably serve everyone on the planet today and into the future is an enormous challenge. An undertaking of this magnitude will be met only with major adjustments informed by thoughtful teaching and practicing problem solving skills through a new educational lens. The principles of agroecology help us focus this lens on the wicked problems …

A Monovalent Mt10-Cvb3 Vaccine Prevents Cvb4-Accelerated Type 1 Diabetes In Nod Mice, Mahima T. Rasquinha, Ninaad Lasrado, Meghna Sur, Kiruthiga Mone, Haowen Qiu, Jean-Jack Riethoven, Raymond A. Sobel, Jay Reddy

Nebraska Center for Virology: Faculty Publications

Enteroviruses, which include Coxsackieviruses, are a common cause of virus infections in humans, and multiple serotypes of the group B Coxsackievirus (CVB) can induce similar diseases. No vaccines are currently available to prevent CVB infections because developing serotype-specific vaccines is not practical. Thus, developing a vaccine that induces protective immune responses for multiple serotypes is desired. In that direction, we created a live-attenuated CVB3 vaccine virus, designated mutant (Mt)10, that offers protection against myocarditis and pancreatitis induced by CVB3 and CVB4 in disease-susceptible A/J mice. Here, we report that the Mt10 vaccine protected against CVB4-triggered type 1 diabetes (T1D) in …

Department of Sociology: Faculty Publications

Can comics effectively convey scientific knowledge about COVID-19 to youth? What types and how many sources of information did youth have about COVID-19 during the pandemic? How are sources of information associated with accurate COVID-19 knowledge? To answer these questions, we surveyed youth in grades 5–9 in a Midwestern United States school district in the winter of 2020–2021. The online survey used measures of COVID-19 knowledge and sources, with an embedded experiment on COVID-19 relevant comics. Guided by an integrated science capital and just-in-time health and science information acquisition model, we also measured level of science capital, science identity, and …

Multiomics Approach Captures Hepatic Metabolic Network Altered By Chronic Ethanol Administration, Isin Tuna Sakallioglu, Bridget Tripp, Jacy Kubik, Carol A. Casey, Paul G. Thomes, Robert Powers

Department of Chemistry: Faculty Publications

Using a multiplatform and multiomics approach, we identified metabolites, lipids, proteins, and metabolic pathways that were altered in the liver after chronic ethanol administration. A functional enrichment analysis of the multiomics dataset revealed that rats treated with ethanol experienced an increase in hepatic fatty acyl content, which is consistent with an initial development of steatosis. The nuclear magnetic resonance spectroscopy (NMR) and liquid chromatography–mass spectrometry (LC-MS) metabolomics data revealed that the chronic ethanol exposure selectively modified toxic substances such as an increase in glucuronidation tyramine and benzoyl; and a depletion in cholesterol-conjugated glucuronides. Similarly, the lipidomics results revealed that ethanol …

MANTER: Journal of Parasite Biodiversity

One Health programs and trajectories are now the apparent standard for exploring the occurrence and distribution of emerging pathogens and disease. By definition, One Health has been characterized as a broadly inclusive, collaborative, and transdisciplinary approach with connectivity across local to global scales, which integrates the medical and veterinary community to recognize health outcomes emerging at the environmental nexus for people, animals, plants, and their shared landscapes. One Health has been an incomplete model, conceptually and operationally, focused on reactive and response-based foundations, to limit the impact of emerging pathogens and emerging infectious diseases and, as such, lacks a powerful …

Extracellular Vesicle Characteristics And Micro Rna Content In Cerebral Palsy And Typically Developed Individuals At Rest And In Response To Aerobic Exercise., Ivan Jose Vechetti Jr, Jessica Norrbom, Björn Alkner, Emma Hjalmarsson, Alexandra Palmcrantz, Eva Pontén, Jessica Pingel, Ferdinand Von Walden, Rodrigo Fernandez-Gonzalo

Department of Nutrition and Health Sciences: Faculty Publications

In this study, the properties of circulating extracellular vesicles (EVs) were examined in cerebral palsy (CP) and typically developed (TD) individuals at rest and after aerobic exercise, focusing on the size, concentration, and microRNA cargo of EVs. Nine adult individuals with CP performed a single exercise bout consisting of 45 min of Frame Running, and TD participants completed either 45 min of cycling (n = 10; TD EX) or were enrolled as controls with no exercise (n = 10; TD CON). Blood was drawn before and 30 min after exercise and analyzed for EV concentration, size, and microRNA …

Phase-Averaged, Frequency Dependence Of Jet Dynamics In A Scaled Up Vocal Fold Model With Full And Incomplete Closure, Nathaniel Wei, Abigail Haworth, Hunter Ringenberg, Michael Krane, Timothy Wei

Department of Mechanical and Materials Engineering: Faculty Publications

This study focuses on frequency dependence effects on glottal jet dynamics with a focus on the physiological condition in which the vocal folds do not fully close. Incomplete closure occurs naturally in children and adult females. But there are also pathological conditions that can be problematic. Experiments were conducted using a 10× scaled-up model in a free surface water tunnel. Two-dimensional vocal fold models with semicircular medial surfaces were stepper motor driven inside a square duct with constant opening and closing speeds. Cases with complete vocal fold closure and incomplete closure to only 15% of the maximum gap were examined. …

Antibody Epitope Profiling Of The Kshv Lana Protein Using Virscan, Sydney J. Bennett, Dicle Yalcin, Sara R. Privatt, Owen Ngalamika, Salum J. Lidenge, John T. West, Charles Wood

School of Biological Sciences: Faculty Publications

The humoral antibody response against Kaposi sarcoma-associated herpesvirus (KSHV) in infected individuals has been characterized demonstrating the latency-associated nuclear antigen (LANA) as the most antigenic KSHV protein. Despite the antigenicity of the protein, specific LANA epitopes have not been systematically characterized. Here, we utilized a bacteriophage T7 library, which displays 56-amino acid KSHV LANA peptides with 28-amino acid overlap (VirScan), to define those epitopes in LANA targeted by antibodies from a cohort of 62 sub-Saharan African Kaposi sarcoma (KS) patients and 22 KSHV-infected asymptomatic controls. Intra- and inter-patient breadth and magnitude of the anti-LANA responses were quantified at the peptide …

Department of Plant Pathology: Faculty Publications

Understanding the genetic diversity and mechanisms underlying genetic variation in pathogen populations is crucial to the development of effective control strategies. We investigated the genetic diversity and reproductive biology of Colletotrichum graminicola isolates which infect maize by sequencing the genomes of 108 isolates collected from 14 countries using restriction site-associated DNA sequencing (RAD-seq) and wholegenome sequencing (WGS). Clustering analyses based on single-nucleotide polymorphisms revealed three genetic groups delimited by continental origin, compatible with short-dispersal of the pathogen and geographic subdivision. Intra- and intercontinental migration was observed between Europe and South America, likely associated with the movement of contaminated germplasm. Low …

Stories, Elizabeth Stuart Phelps, Roxanne Harde , Editor

Zea E-Books Collection

Today, Elizabeth Stuart Phelps (1844–1911) is best known for a handful of her novels: The Gates Ajar (1868), The Silent Partner (1871), and The Story of Avis (1877). During her life, however, the short story was a hugely popular genre in which she was fully invested and where she made a good deal of her living. Stories were her earliest and latest publications, and they were work that she both enjoyed and employed to greater ends. From 1864 to her death in 1911, she published almost one hundred and fifty short stories in the leading periodicals of the day. This …

Coordination Chemistry Of Uranyl Ions With Surface-Immobilized Peptides: An Xps Study, Esha Mishra, Cody M. Schultz, Rebecca Lai, Peter A. Dowben

Department of Physics and Astronomy: Faculty Publications

The coordination chemistry of uranyl ions with surface immobilized peptides was studied using X-ray photoemission spectroscopy (XPS). All the peptides in the study were modified using a six-carbon alkanethiol as a linker on a gold substrate with methylene blue as the redox label. The X-ray photoemission spectra reveal that each modified peptide interacts differently with the uranyl ion. For all the modified peptides, the XPS spectra were taken in both the absence and presence of the uranium, and their comparison reveals that the interaction depends on the chemical group present in the peptides. The XPS results show that, among all …

Glenn Korff School of Music: Faculty Publications

This is the fifth of five on-line text files in which I assemble my research notes about boys’ bands and their bandmasters at the US government’s Native American off-reservation inter-tribal boarding schools. The present document began as an off-shoot from that project into local history concerning the School of Music associated with the University of Nebraska in Lincoln, NE around 1915-1925 and its role in preparing Native American young adults to appear on Circuit Chautauqua programs. They were often graduates of boarding school band programs, and the Haskell school band, in particular, made major Circuit Chautauqua tours with Native American …

Native American Boarding School Bands And Their Bandmasters: Project File 1: General Topics, Peter M. Lefferts

Glenn Korff School of Music: Faculty Publications

To establish a context for the Native American boarding school bands, we start with an important generalization. In the great Victorian era of bands, most were amateur, adult, white, male, community- or workplace-based recreational ensembles. With few exceptions, bands in the 19th century were not ensembles of children or women or family members, and they did not have a home in public primary or secondary schools. With roots in the military band tradition, civilian bands were mostly social organizations for adult males---grown men---"discoursing sweet music" as a kind of fraternal club with voluntary civic functions. Adult amateur men’s bands peppered …

Literature Review On Water Desalination Plant Production And Brine Disposal Methods, Grace Kollars

Department of Environmental Studies: Undergraduate Student Theses

Water scarcity is an issue all around the world because people have a lack of clean and available drinking water. One way this issue can be eased and people can have more access to water is implementing water desalination plants around the world. Since most of the water on earth cannot be drunk, there are ways to turn the over abundance of salty waters we have on this planet into fresh, drinkable water to ease the water insecurity. There are many methods out there that can be used for water desalination, most of them involving membrane technologies. The most efficient …

Outdoor Recreation And Its Effect On Our Relationship With The Environment, Martin Brannaman

Department of Environmental Studies: Undergraduate Student Theses

This study was conducted at the University of Nebraska Outdoor Adventure Center. This study employed a pre-post retrospective assessment looking at individuals' connection with nature after embarking on a direct outdoor experience. A direct outdoor experience is when an individual is outside and not surrounded by manmade structures (Kil, 2016). I believe that after a direct outdoor experience the sample group will have a significant change in their connection to nature. The objective is to measure change in a group's connection to nature, through the Connectedness to Nature Scale (CNS, Mayer & Frantz, 2004). The population was a group of …

Estimation Of Cotton Canopy Parameters Based On Unmanned Aerial Vehicle (Uav) Oblique Photography, Jinyong Wu, Sheng Wen, Yubin Lan, Xuanchun Yin, Jiantao Zhang, Yufeng Ge

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Background: The technology of cotton defoliation is essential for mechanical cotton harvesting. Agricultural unmanned aerial vehicle (UAV) spraying has the advantages of low cost, high efficiency and no mechanical damage to cotton and has been favored and widely used by cotton planters in China. However, there are also some problems of low cotton defoliation rates and high impurity rates caused by unclear spraying amounts of cotton defoliants. The chemical rate recommendation and application should be based upon crop canopy volume rather than on land area. Plant height and leaf area index (LAI) is directly connected to plant canopy structure. …

Genotype Classification Of Moraxella Bovis Using Maldi-Tof Ms Profiles, Hannah G. Olson, John Dustin Loy, Michael L. Clawson, Emily L. Wynn, Matthew M. Hille

Nebraska Center for Virology: Faculty Publications

Moraxella bovis (M. bovis) is regarded as a causative agent of infectious bovine keratoconjunctivitis (IBK), the most common ocular disease of cattle. Recently, whole genome sequencing identified the presence of two distinct genotypes within M. bovis that differ in chromosome content, potential virulence factors, as well as prophage and plasmid profiles. It is unclear if the genotypes equally associate with IBK or if one is more likely to be isolated from IBK lesions. We utilized 39 strains of M. bovis that had previously undergone whole genome sequencing and genotype classification to determine the utility of matrix-assisted laser desorption/ionization …

Ultrafast Electron Diffraction: Visualizing Dynamic States Of Matter, D. Filippetto, P. Musumeci, R. K. Li, B. J. Siwick, M. R. Otto, Martin Centurion, J. P. F. Nunes

Department of Physics and Astronomy: Faculty Publications

Since the discovery of electron-wave duality, electron scattering instrumentation has developed into a powerful array of techniques for revealing the atomic structure of matter. Beyond detecting local lattice variations in equilibrium structures with the highest possible spatial resolution, recent research efforts have been directed toward the long-sought-after dream of visualizing the dynamic evolution of matter in real time. The atomic behavior at ultrafast timescales carries critical information on phase transition and chemical reaction dynamics, the coupling of electronic and nuclear degrees of freedom in materials and molecules, and the correlation among structure, function, and previously hidden metastable or nonequilibrium states …
