Evaluating Opportunities For Integrated Crop Livestock Systems In Eastern Nebraska, Elizabeth Kay Christenson

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Current agricultural systems focused on production of few commodities are facing production, economic, and environmental challenges. To address these challenges, Integrated Crop Livestock Systems (ICLS) have emerged through three primary methods 1) perennial grasslands for grazing and/or hay production, 2) crop residue grazing, and 3) cover crop grazing. To evaluate potential of ICLS mitigating current challenges, a field scale model ICLS was developed in 2015. The ICLS includes 4-ha each of ‘Newell’ smooth bromegrass (Bromus inermis L.), ‘Liberty’ switchgrass (Panicum virgatum L.), and ‘Shawnee’ switchgrass. The ICLS also included 8-ha of continuous corn (Zea mays L.). In …

Understanding The Impact Of Room Acoustic Conditions On The Kurtosis Levels Of Various Noise Signals, William Spallino

Durham School of Architectural Engineering and Construction: Dissertations, Theses, and Student Research

Impulsive noise can be common in certain occupational and recreational settings, such as manufacturing plants, construction sites, and firing ranges. While many regulations and guidelines for noise exposure exist, their mathematical basis is stronger for continuous noise, and concerns have been raised about the possibility that impulsive noise may be more harmful to people’s hearing than those metrics would let on. Much work has been done on establishing metrics that accurately assess the severity and hearing risk associated with impulsive noise, but the effects of room acoustic conditions on those metrics have been heretofore understudied.

This study calculated room impulse …

Long-Term Behavioral Health Care Unbundled: The Impact Of Comorbidity And Aggression On Caregiver Strain And Service Costs For Individuals With Intellectual Disabilities, Kristine Tevis

Department of Psychology: Dissertations, Theses, and Student Research

Individuals with intellectual disabilities represent a unique population with an array of needs. High rates of comorbid mental and physical health conditions as well as the presence of disruptive behaviors pose significant challenges to service providers and funding entities. Existing cost models may underestimate these specialized needs and limit access to required services. Through secondary analysis of archival health data from individuals with intellectual disabilities at one agency in Nebraska (N=73), the current study examines how individual characteristics and aggression influence cost and caregiver strain from a systems theory perspective. Bivariate comparisons revealed that more severe aggression and more frequent …

Metabolic Benefits Of Plant-Based N-3 Polyunsaturated Fatty Acids On Brown Thermogenesis, Kyung Ho Park

Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research

There are two essential fatty acids for humans, a-linolenic acid (ALA) and linoleic acid (LA), which should be taken from foods to maintain health. Once incorporated into cells, ALA and LA, which are omega-3 poly unsaturated fatty acid (n-3 PUFA) and n-6 PUFA respectively, undergo elongation and desaturation to generate longer and more unsaturated fatty acids influencing inflammation and immunological responses. Numerous studies showed a dietary reduction of n-6/n-3 PUFA ratio improves cardiovascular health, inflammation, and insulin resistance. Fish oil, the main resource for n-3 PUFA, is shown to increase these health benefits. In our lab, we investigated the efficacy …

Camberato, Paul R. Carter, Richard Ferguson, David W. Franzen, Daniel E. Kaiser, Newell R. Kitchen, Carrie A.M. Laboski, Emerson Nafziger, Carl J. Rosen, John E. Sawyer, John F. Shanahan

Department of Agronomy and Horticulture: Faculty Publications

Anaerobic potentially mineralizable nitrogen (PMN) combined with preplant nitrate test (PPNT) or pre-sidedress nitrate test (PSNT) may improve corn (Zea mays L.) N management. Forty-nine corn N response studies were conducted across the U.S. Midwest to evaluate the capacity of PPNT and PSNT to predict grain yield, N uptake, and economic optimal N rate (EONR) when adjusted by soil sampling depth, soil texture, temperature, PMN, and initial NH₄–N from PMN analysis. Pre-plant soil samples were obtained for PPNT (0- to 30-, 30- to 60-, 60- to 90-cm depths) and PMN (0- to 30-cm depth) before corn planting …

A Survey Of Dairy-Goat Keeping In Zanzibar, Tiffanie Stone, Charles A. Francis, L. O. Eik

Department of Agronomy and Horticulture: Faculty Publications

Dairy goats with improved genetics for milk production were recently introduced onto small-scale farms in Zanzibar through governmental and non-governmental projects. These projects were meant to support small-scale farmers by improving both income and household nutrition through milk production. No follow up had been conducted to understand what effects dairy goat keeping had on these small-scale farms, or how they could be improved. A survey of 193 dairy goat farmers in Zanzibar was conducted, including 30% and 60% of all dairy goat farmers on Unguja and Pemba, the two largest islands, respectively. The objective was to understand the impact keeping …

Bioinformatic Analysis Of The Gut Microbiota Derived From The Oil Fly Helaeomyia Petrolei From The La Brea Tar Pits, Brian A. Dillard

School of Biological Sciences: Dissertations, Theses, and Student Research

In the early 1930s, Thorpe a prominent entomologist, called for more research into Helaeomyia petrolei larva. These larvae live in the Californian La Brea tar pits where they are exposed to large amounts of polyaromatic hydrocarbons. Molecules like anthracene, phenanthrene, and toluene which should be highly toxic to both the oil fly larvae and its enteric bacteria. This extremophilic gut microbiome has yet to be studied using current day next gen sequencing and bioinformatic techniques. In fact, since Thorpe’s work in the 1930s, there have been only two publications characterizing the oil fly larvae. Both in the early 2000s by …

Effects Of Ndf Digestibility On Lactating Jersey Cows: Observed And Modeled Performance, Kirby Craig Krogstad

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

Improving the digestibility of fiber and our understanding of how to feed it will optimize the ruminants’ niche in our society, which is to convert human inedible products to high quality protein in the form of meat and milk. Neutral detergent fiber (NDF) digestibility has been studied and modeled for decades, but it is increasingly important as livestock production is scrutinized for resource use and sustainability. Increasing the amount of NDF fed and improving models of NDF digestibility will improve sustainability by increasing the precision at which we feed livestock which results in less nutrient and greenhouse gas (GHG) emissions. …

The Role Of Postnatal Adrenergic Manipulation In The Mediation Of Fetal Programming Adaptions In Growth And Skeletal Muscle Glucose Metabolism That Persist In The Juvenile Iugr-Born Lamb, Rachel L. Gibbs

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

Our 1^st study assessed growth deficits in IUGR juvenile lambs and the benefits of treatment with adrenergic and inflammatory mediators. Growth metrics including bodyweight, rate of gain, and crown-rump length were diminished by placental insufficiency-induced IUGR through 2 mo. of age but were recovered by daily clenbuterol or curcumin supplementation. Body composition metrics indicated by bioelectrical impedance, proximate analysis, and loin size revealed that fat-free lean mass, specific muscle group sizes, and protein-to-fat ratios were reduced in unsupplemented IUGR lambs but recovered to or even past controls in clenbuterol-supplemented lambs. From these findings, we conclude that IUGR impairs postnatal …

The Consequences And Correlates Of Racial Identity Discordance: An Explication Of The Social Construction Of Race, Eli X. Ornelas

Department of Sociology: Dissertations, Theses, and Student Research

The current study analyzes the rates at which different racial groups experience identity discordance, or the phenomenon of one’s self-ascribed racial identity not being commensurate with external perceptions of one’s race. While previous research has documented the possibility of discrepancy between self-ascribed and external classifications of racial identities, few empirical studies have sought to determine which racial groups are most susceptible to experiencing identity discordance or investigated specific mechanisms that may contribute to that discordance. Utilizing the 2006 wave of the Portraits of American Life Study (PALS), the current study investigates the rate of identity discordance for Whites, Blacks, Hispanics, …

Epstein Barr Virus-Immortalizedｂlymphocytes Exacerbate Experimental Autoimmune Encephalomyelitis In Xenograft Mice, Pascal Polepole, Alison Bartenslager, Yutong Liu, Thomas M. Petro, Samodha C. Fernando, Luwen Zhang

Nebraska Center for Virology: Faculty Publications

Multiple sclerosis (MS) is the most common autoimmune disorder affecting the central nervous system. Epstein-Barr virus (EBV) is a causative agent for infectious mononucleosis (IM) that is associated with MS pathogenesis. However, the exact mechanism by which EBV, specifically in IM, increases the risk for MS remains unknown. EBV immortalizes primary B lymphocytes in vitro and causes excessive B lymphocyte proliferation in IM in vivo. In asymptomatic carriers, EBV-infected B lymphocytes still proliferate to certain degrees, the process of which is tightly controlled by the host immune systems. Experimental autoimmune encephalomyelitis (EAE) mimics key features of MS in humans …

The Silent Battle On The Budget: The Effect Of Centralized Indexing On Collection Analysis In Primo And Ebsco, Casey D. Hoeve, Christina Geuther

University of Nebraska-Lincoln Libraries: Faculty Publications

Significant cuts to the collections budget and a fire in the main library at Kansas State University transitioned the Libraries toward an increased focus upon electronic resources management. As electronic resource discovery continues to be hampered by market competition between Ex Libris and EBSCO library vendors, difficulties were identified in obtaining accurate usage statistics for resource renewal reviews, particularly EBSCO products. Kansas State University Libraries use the ALMA URM in combination with Primo discovery service, which experiences known resolver complications when paired with EBSCO resources. Technical services librarians and information technology staff tested several workarounds, but the question remains whether …

Professional Military Education In The Marine Corps Reserve: A Narrative Inquiry, Adam Fullerton, Deryl K. Hatch-Tocaimaza, Seth S. Synstelien, Aaron Meltzer

Department of Educational Administration: Faculty Publications

While there are numerous qualitative studies that explore civilian experiences in continuing professional education programs, there is a dearth of research on the professional military education (PME) system. These systems, which sustain continuing education and professional development for more than 2 million active and reserve members of the military, are navigated in a myriad of different ways, depending on the branch of service, active or reserve status, and ability to go to resident PME courses by using an online format. This study, using a narrative inquiry framework, explores the lived experience of seven reserve staff noncommissioned officers (SNCO) as they …

Frontal Vehicle Illumination Via Rear-Facing Lighting Reduces Potential For Collisions With White-Tailed Deer, Travis L. Devault, Thomas W. Seamans, Bradley Blackwell

United States Department of Agriculture Wildlife Services: Staff Publications

nimal–vehicle collisions cause many millions of animal deaths each year worldwide and present a substantial safety risk to people. In the United States and Canada, deer (Odocoileus spp.) are involved in most animal–vehicle collisions associated with human injuries. We evaluated a vehicle-based collision mitigation method designed to decrease the likelihood of deer–vehicle collisions during low-light conditions, when most collisions occur. Specifically, we investigated whether the use of a rear-facing light, providing more complete frontal vehicle illumination than standard headlights alone, enhanced vehicle avoidance behaviors of white-tailed deer (O. virginianus). We quantified flight initiation distance (FID), the likelihood …

Developing Alternatives To Protect Domestic Sheep From Predation In South Africa, David L. Bergman, Nico L. Avenant, Michael J. Bodenchuk, Eddie Steenkamp

United States Department of Agriculture Wildlife Services: Staff Publications

South Africa has approximately 8,000 commercial small livestock farms and 5,800 communal/subsistence farmers throughout the country. Reported rates of small livestock loss to predation range from 3-13% and 0.5-19% from communal farming areas. A range of predators exist on the African continent, but in southern Africa major livestock losses are primarily due to black-backed jackal and caracal. South Africans have been managing caracals and jackals for over 300 years with no elimination of predation. During the aforementioned time frame, producers have used and/or developed a number of techniques including lethal, nonlethal, and integrated predator damage management to address predation losses. …

Mindfulness, Megan Paul

Umbrella Summaries

What is mindfulness?

Mindfulness is described as “paying attention in a particular way: on purpose, in the present moment, and nonjudgmentally” (Kabat-Zinn, 1994, p. 22). Instead of being on autopilot and reacting in reflexive and mindless ways, perhaps with a focus on the past or the future, it is about being fully aware of and present in the moments of our lives. The nonjudgmental aspect is about not leaping to “likes and dislikes, opinions and prejudices, projections and expectations” (Kabat-Zinn, 1994, p. 23) and instead observing without evaluating. Mindfulness is considered both a trait and a state. Trait mindfulness refers …

Psychological And Neurobiological Mechanisms Underlying The Decline Of Maternal Behavior, Ming Li

Department of Psychology: Faculty Publications

The maternal behavior decline is important for the normal development of the young and the wellbeing of the mother. This paper reviews limited research on the factors and mechanisms involved in the rat maternal behavior decline and proposes a multi-level model. Framed in the parent-offspring conflict theory (an ultimate cause) and the approach-withdrawal model (a proximate cause), the maternal behavior decline is viewed as an active and effortful process, reflecting the dynamic interplay between the mother and her offspring. It is instigated by the waning of maternal motivation, coupled with the increased maternal aversion by the mother in responding to …

Automatic Delamination Segmentation For Bridge Deck Based On Encoder-Decoder Deep Learning Through Uav-Based Thermography, Chongsheng Cheng, Zhexiong Shang, Zhigang Shen

Department of Construction Engineering and Management: Faculty Publications

Concrete deck delamination often demonstrates strong variations in size, shape, and temperature distribution under the influences of outdoor weather conditions. The strong variations create challenges for pure analytical solutions in infrared image segmentation of delaminated areas. The recently developed supervised deep learning approach demonstrated the potentials in achieving automatic segmentation of RGB images. However, its effectiveness in segmenting thermal images remains under-explored. The main challenge lies in the development of specific models and the generation of a large range of labeled infrared images for training. To address this challenge, a customized deep learning model based on encoder-decoder architecture is proposed …

Climate Change Impacts The Subsurface Transport Of Atrazine And Estrone Originating From Agricultural Production Activities, Renys Enrique Barrios, Simin Akbariyeh, Chuyang Liu, Khalid Muzamil Gani, Margarita T. Kovalchuk, Xu Li, Yusong Li, Daniel D. Snow, Zhenghong Tang, John Gates, Shannon L. Bartelt-Hunt

Nebraska Water Center: Faculty Publications

Climate change will impact soil properties such as soil moisture, organic carbon and temperature and changes in these properties will influence the sorption, biodegradation and leaching of trace organic contaminants to groundwater. In this study, we conducted a modeling case study to evaluate atrazine and estrone transport in the subsurface under current and future climate conditions at a field site in central Nebraska. According to the modeling results, in the future, enhanced evapotranspiration and increased average air temperature may cause drier soil conditions, which consequently reduces the biodegradation of atrazine and estrone in the water phase. On the other hand, …

Employment Interviews, Megan Paul

Umbrella Summaries

What are employment interviews?

Employment interviews are defined as “a personally interactive process of one or more people asking questions orally to another person and evaluating the answers for the purpose of determining the qualifications of that person in order to make employment decisions” (Levashina, Hartwell, Morgeson, & Campion, 2014, p. 243). Interviews are often loosely described as being either structured or unstructured, varying in the extent to which interviewers have freedom and flexibility in carrying out the interview (Huffcutt & Arthur, 1994). Within this broad dichotomy, there are many structural aspects on which interviews can differ (Campion, Palmer, & …

Vertebrates On The Brink As Indicators Of Biological Annihilation And The Sixth Mass Extinction, Gerardo Ceballos, Paul R. Ehrlich, Peter H. Raven

Harold W. Manter Laboratory of Parasitology: Library Materials

The ongoing sixth mass species extinction is the result of the destruction of component populations leading to eventual extirpation of entire species. Populations and species extinctions have severe implications for society through the degradation of ecosystem services. Here we assess the extinction crisis from a different perspective. We examine 29,400 species of terrestrial vertebrates, and determine which are on the brink of extinction because they have fewer than 1,000 individuals. There are 515 species on the brink (1.7% of the evaluated vertebrates). Around 94% of the populations of 77 mammal and bird species on the brink have been lost in …

The Challenge Of Consumer Diversity In Servicescapes: An Investigation Of Consumer And Service Provider Experiences, Abigail Nappier Cherup

College of Business: Dissertations, Theses, and Student Research

While consumer diversity continues to grow in importance, evidence suggests that firms have yet to align their thoughts and activities with diverse consumers’ needs. This is especially true for consumers who have a hidden stigmatized identity. On the one hand, consumers with such concealable stigmatized identities must make the decision to reveal or conceal their identity in a variety of situations, including service environments. On the other hand, many service providers are working to offer inclusive service environments yet struggle to do so. Therefore, this ethnographic dissertation has two objectives: to 1) conceptualize practices unique to consumers with a concealable …

Perceptions Of Human Security Among Islamic School Students, Parents And Teachers In Southern Thailand’S Subnational Conflict Zone, Tarik Abdel-Monem, Mahsoom Sateemae, Suhaimee Sateemae, Sareeha Tayongmat, Stacey Hoffman, Mark Dekraai

University of Nebraska Public Policy Center: Publications

Since 2004, close to 7,000 people have died in Thailand’s domestic insurgency in its three Muslim-majority southern provinces, one of the longest-running, low-intensity conflicts in Southeast Asia. This study assesses perceptions of human security threats in the area among a sample of students, their parents, and teachers of Islamic private schools (n = 427, n = 331, n = 51, respectively), and how they relate to perceptions of government actors and other community institutions. Questionnaire items were drawn from the World Values Survey Wave 6. Focus groups and interviews were also conducted to deepen our understanding of conflict related dynamics.
