Job Satisfaction, Sarah Stepanek, Megan Paul

Umbrella Summaries

What is job satisfaction?

Job satisfaction is generally thought of as the degree to which an individual likes or dislikes their job (Spector, 1997). Along with organizational commitment, it is one of the most commonly studied job attitudes and is used as a way to gauge how employees feel about their jobs and as a reflection of how well the organization is functioning. Job satisfaction is commonly considered as either “a global feeling about the job or as a related constellation of attitudes about various aspects or facets of the job” (Spector, 1997, p. 2). Thus, job satisfaction is …

Embracing Uncertainty: A Narrative Case Study On Teacher-Learner Relationships Through Restorative Justice Practices In Education, Zachary Schafer, Guy Trainin

Department of Teaching, Learning, and Teacher Education: Theses and Other Student Research

Restorative justice practices in educational settings recognising trauma and extreme life circumstances have become increasingly relevant since the COVID-19 pandemic and the growing impacts of climate change. This narrative inquiry uses Clandinin and Connelly’s suggestions for data collection and narrative structure to describe the interactions between one teacher and one learner over the course of two years in a programme created as an alternative to school suspension. Using a dual framework combining a variety of perspectives from restorative justice practices and Chen’s model of uncertainty management in science education, the researchers iteratively and thematically analysed the teacher-learner interactions. The storied …

Ludemann, Nathan Wanner, Pauline Chivenge, Achim Dobermann, Rasmus Einarsson, Patricio Grassini, Armelle Gruere, Kevin Jackson, Luis Lassaletta, Federico Maggi, Griffiths Obli-Laryea, Martin K. Van Ittersum, Srishti Vishwakarma, Xin Zhang, Francesco N. Tubiello

Department of Agronomy and Horticulture: Faculty Publications

Nutrient budgets help to identify the excess or insufficient use of fertilizers and other nutrient sources in agriculture. They allow for the calculation of indicators, such as the nutrient balance (surplus if positive or deficit if negative) and nutrient use efficiency, that help to monitor agricultural productivity and sustainability across the world. We present a global database of country-level budget estimates for nitrogen (N), phosphorus (P) and potassium (K) on cropland. The database, disseminated in FAOSTAT, is meant to provide a global reference, synthesizing and continuously updating the state of the art on this topic. The database covers 205 countries …

Using Genetic Comparisons Of Populations From Arizona, Mexico, And Texas To Investigate Fall Armyworm Migration In The American Southwest, Rodney N. Nagoshi, Ashley E. Tessnow, Yves Carrière, Jeff Bradshaw Dr., Kyle Harrington, Gregory A. Sword, Robert L. Meagher

Department of Entomology: Faculty Publications

Fall armyworm (FAW) is a global agricultural pest, causing substantial economic losses in corn and many other crops. Complicating efforts to control this pest is its capacity for long distance flights, which has been described in greatest detail for the central and eastern sections of the United States. FAW infestations are also routinely found in agricultural areas in southern Arizona, which lie beyond the western limits of the mapped migratory pathways. Climate suitability analysis found that the affected Arizona locations cannot support permanent FAW populations, indicating that these FAW most likely arise from annual migrations. A better understanding of this …

Measurements Of Azimuthal Anisotropy Of Nonprompt D0 Mesons In Pbpb Collisions At √𝑠Nn = 5.02 Tev, A. Tumasyan

Department of Civil and Environmental Engineering: Faculty Publications

Measurements of the elliptic (𝑣₂) and triangular (𝑣₃) azimuthal anisotropy coefficients are presented for D⁰ mesons produced in b hadron decays (nonprompt D⁰ mesons) in lead-lead collisions at √ 𝑠_NN = 5.02 TeV. The results are compared with previously published charm meson anisotropies measured using prompt D⁰ mesons. The data were collected with the CMS detector in 2018 with an integrated luminosity of 0.58 nb⁻¹. Azimuthal anisotropy is sensitive to the interactions of quarks with the hot and dense medium created in heavy ion collisions. Comparing results for prompt and …

Molecular Species Delimitation Of Marine Trematodes Over Wide Geographical Ranges: Schikhobalotrema Spp. (Digenea: Haplosplanchnidae) In Needlefishes (Belonidae) From The Pacific Ocean And Gulf Of Mexico, Gerardo Pérez-Ponce De León, Brenda Solórzano-García, Daniel C. Huston, Berenit Mendoza-Garfias, Jhonatan Cabañas-Granillo, Scott C. Cutmore, Thomas H. Cribb

Harold W. Manter Laboratory of Parasitology: Library Materials

Geographical distribution plays a major role in our understanding of marine biodiversity. Some marine fish trematodes have been shown to have highly restricted geographical distributions, while some are known to occur over very wide ranges; however, very few of these wide distributions have been demonstrated genetically. Here, we analyse species of the genus Schikhobalotrema (Haplosplanchnidae) parasitizing beloniforms from the tropical west Pacific, the eastern Pacific and the Gulf of Mexico (GoM). We test the boundaries of these trematodes by integrating molecular and morphological data, host association, habitat of the hosts and geographical distribution, following a recently proposed and standardized delineation …

Disentangling Trend Risk And Basis Risk With Functional Time Series, Yanxin Liu, Johnny Siu-Hang Li

Department of Finance: Faculty Publications

In recent multi-population stochastic mortality models, one critical scientific issue is the vague distinction between trend risk and population basis risk. In particular, the cross- and auto-correlations between the innovations of the latent factors representing the common trend and the population-specific trends are often assumed to be non-existent, although they are possibly statistically significant. While it is theoretically possible to capture such correlations by treating the latent factors as a vector time series, the resulting model would contain a large number of parameters, which may in turn lead to robustness problems. In this paper, we address these issues by the …

Lactic Acid Bacterial Surface Display Of Scytovirin Inhibitors For Anti-Ebolavirus Infection, Joshua Wiggins, Ngan Nguyen, Wenzhong Wei, Leah Liu Wang, Haley Hollingsead Olson, Shi-Hua Xiang

Nebraska Center for Virology: Faculty Publications

Scytovirin (SVN) is a lectin from cyanobacteria which has a strong inhibitory activity against Ebola virus infection. We engineered scytovirin as the inhibitor for surface display of lactic acid bacteria to block Ebola virus infection. Two different bacterial strains (Lactobacillus casei and Lactococcus lactis) were successfully engineered for scytovirin expression on the bacterial surface. These bacteria were found to be effective at neutralizing pseudotyped Ebolavirus in a cell-based assay. This approach can be utilized for prophylactic prevention, as well as for treatment. Since lactic acid bacteria can colonize the human body, a long-term efficacy could be achieved. Furthermore, …

The Pseudomonas Syringae Pv. Tomato Dc3000 Effector Hopd1 Interferes With Cellular Dynamics Associated With The Function Of The Plant Immune Protein Atnhr2b, Luis Francisco Marín-Ponce, Catalina Rodríguez-Puerto, Perla Rocha-Loyola, Clemencia M. Rojas

Department of Plant Pathology: Faculty Publications

The plant pathogenic bacterium Pseudomonas syringae pv. tomato DC3000 (Pst DC3000) causes disease in tomato, in the model plant Arabidopsis thaliana, and conditionally in Nicotiana benthamiana. The pathogenicity of Pst DC3000 is mostly due to bacterial virulence proteins, known as effectors, that are translocated into the plant cytoplasm through the type III secretion system (T3SS). Bacterial type III secreted effectors (T3SEs) target plants physiological processes and suppress defense responses to enable and support bacterial proliferation. The Pst DC3000 T3SE HopD1 interferes with plant defense responses by targeting the transcription factor NTL9. This work shows that HopD1 also targets …

Department of Psychology: Faculty Publications

The goal of this study was to assess the joint role of race/ethnicity and a health insurance coverage type (private, Medicare, Medicaid) in current cigarette use among adults in the U.S. Data from the 2019 Tobacco Use Supplement and the 2019 Annual Social and Economic Supplement of the Current Population Survey were merged (n = 39,882). Bivariate associations between each coverage type and smoking prevalence were examined within each of six racial/ethnic groups. A multiple logistic regression model (for the odds of current cigarette use) was estimated to explore the interactions between race/ethnicity and an indicator of each type of …

Disruption Of Semiochemical-Mediated Movement By The Immature Trogoderma Variabile Baillon And Trogoderma Inclusum Le Conte (Coleoptera: Dermestidae) After Exposure To Long-Lasting Insecticide-Incorporated Netting, Sabita Ranabhat, Michael J. Domingue, Luke Lebar, Georgina Bingham, Kun Yan Zhu, William R. Morrison Iii

Department of Entomology: Faculty Publications

BACKGROUND: Highly mobile stored product insects may be able to readily orient in response to food cues and pheromones to attack durable commodities at each link of the postharvest supply chain. A 0.4% deltamethrin-incorporated long-lasting insecticide-incorporated netting (LLIN) is a successful novel preventative integrated pest management (IPM) tactic to intercept dispersing insects after harvest. However, it is unknown whether exposure to LLIN may affect olfaction and orientation to important semiochemicals by immature stored product dermestids, therefore the aim of this study was to assess whether exposure to LLIN disrupts the normal olfactory and chemotactic behavior of warehouse beetle, Trogoderma variabile …

School of Computing: Faculty Publications

Pancreatic ductal adenocarcinoma (PDAC) presents a critical global health challenge, and early detection is crucial for improving the 5-year survival rate. Recent medical imaging and computational algorithm advances offer potential solutions for early diagnosis. Deep learning, particularly in the form of convolutional neural networks (CNNs), has demonstrated success in medical image analysis tasks, including classification and segmentation. However, the limited availability of clinical data for training purposes continues to represent a significant obstacle. Data augmentation, generative adversarial networks (GANs), and cross-validation are potential techniques to address this limitation and improve model performance, but effective solutions are still rare for 3D …

The Influence Of Grazing Systems On Bird Species Richness And Density In The Nebraska Sandhills, Silka L.F. Kempema, Walter H. Schacht, Larkin A. Powell

School of Natural Resources: Faculty Publications

Grazing is the de facto method of habitat management used in much of the Nebraska Sandhills. Ranchers use a variety of grazing systems, and our goal was to evaluate the effects of systems on grassland birds. We estimated the species richness and density of grassland birds for three grazing systems used on private ranches: long, medium, and short duration grazing systems. We observed sixty species, and the grazing system with pastures utilizing long duration grazing periods had the highest estimates of species richness as well as the most heterogeneous habitat structure. Differences in species richness among systems were most pronounced …

Tulathromycin Metaphylaxis Increases Nasopharyngeal Isolation Of Multidrug Resistant Mannheimia Haemolytica In Stocker Heifers, William B. Crosby, Brandi B. Karisch, Lari M. Hiott, Lee J. Pinnell, Alexandra Pittman, Jonathan G. Frye, Charlene R. Jackson, John Dustin Loy, William B. Epperson, John Blanton Jr., Sarah F. Capik, Paul S. Morley, Amelia R. Woolums

School of Veterinary and Biomedical Sciences: Faculty Publications

Bovine respiratory disease (BRD) is a leading cause of disease in feedlot and stocker calves with Mannheimia haemolytica (MH) as one of the most common etiologies. One of the most effective means of controlling BRD is through metaphylaxis, which involves administering antimicrobials to all animals at high risk of developing BRD. However, increasing prevalence of multidrug resistant (MDR) MH may reduce efficacy of metaphylaxis due to decreased susceptibility to drugs used for metaphylaxis. Primarily, this study aimed to determine the effect of tulathromycin metaphylaxis and subsequent BRD treatment on antimicrobial resistance (AMR) in MH isolated from stocker calves. Secondary objectives …

Radiofrequency Inactivation Of Salmonella In Black Pepper And Dried Basil Leaves Using In-Package Steaming, Surabhi Wason, Rossana Villa-Rojas, Jeyamkondan Subbiah

Department of Food Science and Technology: Faculty Publications

Radiofrequency (RF) heating has been extensively studied for pasteurizing low‐moisture foods. Currently, bulk foods are treated with radiofrequency; potential cross‐contamination may occur during packaging of pasteurized products. As an alternative, in‐package RF processing was evaluated for Salmonella inactivation on black peppercorns and dried basil leaves and prevention of cross‐contamination during storage postprocessing. Inpackage steaming refers to the process in which the samples were heated in a steam vent package to generate and retain steam during the treatment. This treatment achieved good heating uniformity which could be because of the circulation of steam within the package. One‐way steam vent allowed the …

Drought In The Breadbasket Of America And The Influence Of Oceanic Teleconnections, Olivia G. Campbell, Gregory B. Goodrich

School of Natural Resources: Faculty Publications

From 1980 to 2020, drought events accounted for only 11.4% of the billion-dollar disasters in the United States (U.S.), yet caused the second-highest total amount in damages, at USD 236.6 billion. With the average cost of a drought being upwards of USD 9.5 billion, these natural disasters can create serious problems in agriculture. Drought is defined as a period of below-average precipitation that causes damage to agriculture and water supplies. Previous research has linked drought events in the U.S. Great Plains to oceanic teleconnections in the Pacific and Atlantic basins, indicating the influence of El Niño—Southern Oscillation (ENSO), the Pacific …

United States Department of Agriculture Wildlife Services: Staff Publications

Highly pathogenic avian influenza viruses (HPAIVs) of subtype H5 of the Gs/GD/96 lineage remain a major threat to poultry due to endemicity in wild birds. H5N1 HPAIVs from this lineage were detected in 2021 in the United States (US) and since then have infected many wild and domestic birds. We evaluated the pathobiology of an early US H5N1 HPAIV (clade 2.3.4.4b, 2021) and two H5N8 HPAIVs from previous outbreaks in the US (clade 2.3.4.4c, 2014) and Europe (clade 2.3.4.4b, 2016) in chickens and turkeys. Differences in clinical signs, mean death times (MDTs), and virus transmissibility were found between chickens and …

An Analysis Of Racially Disparate Impacts On Housing For The City Of Tukwila, Washington, Neil Tabor

Community and Regional Planning Program: Professional Projects

The housing crisis within the Pacific Northwest of the United States has prompted action from Washington legislators, resulting in Governor Inslee identifying housing as a key priority and the legislature passing a number of forward-thinking bills in the last half decade, requiring the allocation of more resources, and asking more of jurisdictions to address current housing needs and anticipated future growth. Layered within the planning efforts for future growth are concerns and considerations for the potential of new housing development to perpetuate and exacerbate societal inequities built on discriminatory housing policies and practices of generations past and present.

Enzyme Kinetics Of Deoxyuridine Triphosphatase From Western Corn Rootworm, Carlos Riera‑Ruiz, Hideaki Moriyama

School of Biological Sciences: Faculty Publications

Objective The Western corn rootworm (WCR), Diabrotica virgifera virgifera, is a highly adaptable insect pest that has evolved resistance to a variety of control strategies, including insecticides. Therefore, it is interesting to examine how housekeeping proteins in WCR have been changed under WCR-controlling strategies. In this study, we focused on one of such proteins in WCR, a ubiquitous enzyme 5’-triphosphate nucleotidohydrolase (dUTPase). In the thymidine synthetic pathway, dUTPase hydrolyzes deoxyuridine triphosphate (dUTP) and supplies the substrate, deoxyuridine monophosphate, for the thymidylate synthase (TS). It decreases the cellular content of uracil, reducing uracil misincorporation into DNA. Suppressing the dUTPase activity, …

The northern corn rootworm, Diabrotica barberi Smith & Lawrence (Coleoptera: Chrysomelidae) is a major pest of maize in the United States Corn Belt. Recently, resistance to Bacillus thuringiensis (Bt) maize was reported in North Dakota and increased use of Bt maize hybrids could facilitate resistance evolution in other maizeproducing states. In this study, susceptibility to Bt proteins was evaluated in wild D. barberi populations from 8 fields collected in 5 different states (Minnesota, Missouri, Nebraska, Iowa, and North Dakota). Field populations were compared to a susceptible D. barberi colony in seedling and diet toxicity assays conducted with 3 …

Analyzing Major Elements Of Crash Injury Severity Involving Priority-I Detriments Of Vision-Zero Plan, Muhammad Umer Farooq, Cole Madson, Aemal Khattak

Mid-America Transportation Center: Final Reports and Technical Briefs

Road traffic crashes result in significant economic losses for individuals, their families, and entire nations. These losses stem from the expenses associated with injury treatment, as well as the productivity lost due to fatalities or disabilities caused by these injuries. The 2030 Agenda for Sustainable Development set an ambitious target of halving the global number of fatalities and injuries from road traffic crashes by 2020 and achieving zero deaths by 2030, commonly referred to as the 'Target Zero Plan.' The Target Zero Plan prioritizes traffic safety issues into three distinct levels. The three priority levels are determined based on the …

Department of Mechanical and Materials Engineering: Faculty Publications

Background: Engineering education seeks to prepare students for engineering practice, but the concept of preparedness is often ill-defined. Moreover, findings from studies of different populations or in different contexts vary regarding how well new graduates are prepared. These variations, coupled with the lack of clarity, suggest the need to better understand what it means to be prepared for engineering work.

Purpose: This study contributes to research on workplace preparation by exploring how new graduates describe being prepared for engineering work.

Method: Applying secondary analysis to data from the multi-institution Capstone To Work (C2W) project, we used thematic …

Exploring Statistical And Machine Learning-Based Missing Data Imputation Methods To Improve Crash Frequency Prediction Models For Highway-Rail Grade Crossings, Muhammad Umer Farooq, Aemal Khattak

Mid-America Transportation Center: Final Reports and Technical Briefs

Highway-rail grade crossings (HRGCs) are critical spatial locations of transportation safety because crashes at HRGCs are often catastrophic, potentially causing several injuries and fatalities. Every year in the United States, a significant number of crashes occur at these crossings, prompting local and state organizations to engage in safety analysis and estimate crash frequency prediction models for resource allocation. These models provide valuable insights into safety and risk mitigation strategies for HRGCs. Furthermore, the estimation of these models is based on inventory details of HRGCs, and their quality is crucial for reliable crash predictions. However, many of these models exclude crossings …

Road Work Zone Safety: Investigating Injury Severity In Motor Vehicle Crashes Using Random Effects Multinomial Logit Model, Aemal Khattak, Muhammad Umer Farooq

Mid-America Transportation Center: Final Reports and Technical Briefs

Work zones serve the purpose of facilitating maintenance and rehabilitation activities on roadways. However, these areas can also present unforeseen conditions to drivers, including narrowed right-of-way, lane shifts, and traffic disruptions. These conditions frequently contribute to vehicular crashes within work zones, resulting in property damage, injuries, and even loss of life. This paper aims to highlight work zone related crash data insights and presents statistical estimates of significant determinants of injury severity by analyzing ten-year crash data (2008-2018) from Nebraska, USA. The examination of crash data helped in highlighting work zone attributes that are empirically associated with serious injury crashes …

Using Encrypted Genotypes And Phenotypes For Collaborative Genomic Analyses To Maintain Data Confidentiality, Tianjing Zhao, Fangyi Wang, Richard Mott, Jack Dekkers, Hao Cheng

Department of Animal Science: Faculty Publications

To adhere to and capitalize on the benefits of the FAIR (findable, accessible, interoperable, and reusable) principles in agricultural genome- to-phenome studies, it is crucial to address privacy and intellectual property issues that prevent sharing and reuse of data in research and industry. Direct sharing of genotype and phenotype data is often prohibited due to intellectual property and privacy concerns. Thus, there is a pressing need for encryption methods that obscure confidential aspects of the data, without affecting the outcomes of certain statistical analyses. A homomorphic encryption method for genotypes and phenotypes (HEGP) has been proposed for single-marker regression in …

Infrastructure System Obstacles And Technology Adoption By Firms In Transition Countries, John Anderson, Muazzam Toshmatova

Department of Economics: Faculty Publications

This study uses business survey data to analyze firm perceptions of infrastructure systems in transition countries as obstacles to conducting business. Factors that contribute to reported perceptions are modeled, including country macroeconomic conditions, firm characteristics, and measures of overall reforms and infrastructure system reforms. Identified obstacles arise from binding constraints that limit economic growth, reflect implicit shadow costs, and signal areas in need of policy reform or infrastructure investment. The analysis covers electric power, telecommunications, transportation, and water and wastewater infrastructure systems. Also examined is whether transition indicators of reforms, intended to reflect improvements, are associated with perceptions of obstacles. …

Integrated Flood Risk Assessment Of Properties And Associated Population At County Scale For Nebraska, Usa, Shivendra Srivastava, Tirthankar Roy

Department of Civil and Environmental Engineering: Faculty Publications

Risk assessment of properties and associated population was conducted for the state of Nebraska, leveraging only open-source datasets. The flood risk framework consisted of interactions among drivers, i.e. hazard, exposure, vulnerability, and response, to assess the risks related to properties and associated populations. To quantify hazard on a county scale, we considered properties at risk of flooding based on a flood score (a higher score represents a greater chance of flooding). Exposure was quantified by considering population density at the county level. We quantified vulnerability under four categories: social, ecological, economic, and health. Response, a relatively newer component in flood …
