Local adaptation is an important process in plant evolution, which can be impacted by differential pathogen pressures along environmental gradients. However, the degree to which pathogen resistance loci vary in effect across space and time is incompletely described.

To understand how the genetic architecture of resistance varies across time and geographic space, we quantified rust (Puccinia spp.) severity in switchgrass (Panicum virgatum) plantings at eight locations across the central USA for 3 yr and conducted quantitative trait locus (QTL) mapping for rust progression.

We mapped several variable QTLs, but two large-effect QTLs which we have named Prr1 and Prr2 were …

United States Department of Agriculture Wildlife Services: Staff Publications

Reliable and efficient population estimates are a critical need for effective management of invasive wild pigs (Sus scrofa). We evaluated the use of 10‐day camera grids for rapid population assessment (RPA) of wild pigs at 3 study sites that varied in vegetation communities and wild pig densities. Study areas included Buck Island Ranch, Florida; Tejon Ranch, California; and the Savannah River Site, South Carolina, USA, during 2016–2018. Rapid population assessments grids were composed of baited camera traps spaced approximately 500 or 750 m apart. Two RPA grids were deployed per study site and each grid was deployed twice (4–6 months …

Training And Experience Evaluations, Kate Stephenson, Megan Paul

Umbrella Summaries

What are training and experience evaluations?

Training and experience (T&E) include previous work and volunteer experience, education or other training, and credentials (Schneider, 1994). Evaluations of T&E are often included in employee selection procedures to screen and rate applicants based on information provided on resumes, applications, or other documents. These evaluations attempt to identify future successful employees by examining and applying systematic, judgment-based ratings to this information (McDaniel, Schmidt, & Hunter, 1988). The idea behind T&E evaluations is that past behavior is a good predictor of future behavior, and people with experience are more committed and motivated to perform well …

Relationships Between Survival And Habitat Suitability Of Semi- Aquatic Mammals, Isidro Barela, Leslie M. Burger, Jimmy Taylor, Kristine O. Evans, Ryo Ogawa, Lance Mcclintic, Guiming Wang

United States Department of Agriculture Wildlife Services: Staff Publications

Spatial distribution and habitat selection are integral to the study of animal ecology. Habitat selection may optimize the fitness of individuals. Hutchinsonian niche theory posits the fundamental niche of species would support the persistence or growth of populations. Although niche-based species distribution models (SDMs) and habitat suitability models (HSMs) such as maximum entropy (Maxent) have demonstrated fair to excellent predictive power, few studies have linked the prediction of HSMs to demographic rates. We aimed to test the prediction of Hutchinsonian niche theory that habitat suitability (i.e., likelihood of occurrence) would be positively related to survival of American beaver (Castor canadensis), …

Textile Production In The Papyri: The Case Of Private Request Letters, Aikaterini Koroli

Egyptian Textiles and Their Production: ‘Word’ and ‘Object’

Throughout the “papyrological millennium”, that is from the 3rd century BC to the 8th century AD, both administrative and private life in Egypt were largely based on letters. Apart from oral communication, letter writing, mostly on papyri and ostraca, was the only available form of communication for the inhabitants of the land of Nile when they needed to get in touch and exchange information with people who did not live in their immediate surroundings. Papyrus letters, written by and sent to private, ordinary people and not to the authorities, composed in the Greek vernacular and intended to fulfill a wide …

Predictors And Impact Of Psychotherapy Side Effects In Young Adults, Tierney K. Lorenz

Department of Psychology: Faculty Publications

What should we tell our younger clients—who may or may not have chosen to come to therapy—about possible risks of engaging in psychotherapy? To explore this question, we examined psychotherapy side effects in 366 young adults with a history of psychotherapy or counseling. Psychotherapy side effects were common, with 41% of participants reporting at least one. Perceived lack of control over the decision of when and how to engage in therapy was the strongest predictor of experiencing therapy side effects. Of the different kinds of side effects, feeling that therapy had gone on too long and experiencing worsening of existing …

Groundwater Quality In The High Plains Aquifer

United States Geological Survey: Publications

Groundwater provides nearly 50 percent of the Nation’s drinking water. To help protect this vital resource, the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) Project assesses groundwater quality in aquifers that are important sources of drinking water. The High Plains aquifer constitutes one of the important aquifers being evaluated.

The High Plains aquifer underlies an area of about 169,000 square miles, which is populated by about 2 million people in parts of eight western states (Colorado, Kansas, Nebraska, New Mexico, Oklahoma, Texas, South Dakota, and Wyoming). The aquifer ranks 13th in the Nation as a source of groundwater for …

In a recent correspondence, the Swedish non-profit organization ChemSec announced the addition of carbon nanotubes to the SIN (‘Substitute It Now’) list1. Carbon nanotubes were added as an entire material class that “should be restricted or banned in the EU.” We believe that this recommendation confuses researchers and the public as it is based on evidence from a very narrow subset of data. Such a designation will likely hinder innovations that could lead to safe and effective applications of carbon nanotubes. Furthermore, this line of reasoning could damage other fields of science and technology, if applied similarly. We have worked …

Tourism’S Impacts On Local Populations, Morgan Glup

Honors Program: Senior Projects (Public)

This thesis discusses the various impacts of tourism on local populations. Despite the growth of tourism industry, only a handful of anthropological studies about the impact of tourism on local population exist. Therefore, this thesis is focused on the study of tourism by anthropologists as there is much about tourism that lends itself well to being studied from an anthropological perspective. Issues relevant to anthropology such as political economy, social change, and cultural identity are directly affected by tourism. A brief overview of the work done by anthropologists on tourism and local populations is discussed. Many anthropological studies of tourism, …

After beginning with an introduction to rural population trends and population sustainability in rural towns, this dissertation gives an overview of population change in rural Nebraska towns between 1950 and 2010. Following a series of maps depicting the changes in rural Nebraska towns between these two censuses, six case studies are used to explore the growth of individual towns. A discussion on the characteristics of growing rural towns in Nebraska follows these case studies.

The dissertation then continues by discussing statewide rural residential decision making and place attachment based on data collected by the Nebraska Roots Migration Survey. Following a …

Counternarratives Of Success: A Narrative Inquiry Into The Life Experiences Of Prior-Enlisted Reserve Officers Navigating Higher Education, Adam B. Fullerton

Department of Educational Administration: Dissertations, Theses, and Student Research

The current extant literature on student veterans describes the student veteran population in monolithic terms through a deficit perspective. With reserve servicemembers making up 33% of the veteran population (VA, 2018), reservists move beyond tokenism (Kanter, 1978;1987) and need to be explored separately. This separation enhances the understanding of their experiences in working towards educational attainment and the differences from the traditional student veteran identity. To engage in the study of this subpopulation, a narrative inquiry into the lived experience of three Marine officers who obtained their degrees while serving as enlisted reservists was conducted.

This study used Veteran Critical …

Understanding The Relationship Between Child Internalizing Problems And Familial Cohesion Following Child Sexual Abuse: The Moderating Role Of Caregiver Abuse History, Erika Boohar

Honors Program: Senior Projects (Public)

Due to the heterogeneous nature of symptoms in survivors of child sexual abuse (CSA), extensive research is needed to understand the complexity and further improve intervention practices. This study examined the relationship between risk and outcome factors, specifically caregiver history of emotional abuse and youths’ internalizing problems, and their influence on familial cohesion following CSA. Using a moderation model, it was hypothesized increased child internalizing problems would be related to decreased family cohesion when caregivers have an extensive history of emotional abuse. Participants were 215 non-offending caregivers of sexually abused children attending Project SAFE (Sexual Abuse Family Education), a 12-week …

Does Money Buy Healthiness: An Examination Of The Effects Of Socioeconomic Indicators On Physical And Mental Health, Caleb Nigrin

Honors Program: Senior Projects (Public)

The purpose of this thesis is to examine the impact of socioeconomic status indicators on physical and mental health. This study hypothesizes that higher socioeconomic status indicators are correlated with better physical and mental health while examining the extent of these relationships. In order to determine this, previous literature regarding health and socioeconomic status will be evaluated. The results of the General Social Survey (2016) will be used to test the effects of socioeconomic status on health using regression analysis. The responses of 1418 participants were used in this analysis, controlling for age, gender, race, political ideology, and religiosity. Two …

Differences In Psychological Distress For United States Native And Foreign Born Populations: Testing For Mediation Of Neighborhood Satisfaction, Poverty, And Health Insurance, Madison L. Woodward

Honors Program: Senior Projects (Public)

The current study examines the difference in frequency of psychological distress between people born in the United States and people born outside of the United States. Further, this study tested for mediating effects of neighborhood satisfaction, poverty status, and health insurance. This study included data from the National Health Interview Survey. Those born outside of the United States were found to report slightly better mental health outcomes. They experienced psychological distress at a lower rate than those born in the United States. Neighborhood satisfaction, living above the poverty line, and having health insurance were all negatively associated with psychological stress. …

Evaluation Of The Overall Binding Of Acetohexamide And Tolbutamide With Methyl Glyoxal-Modified Hsa By High-Performance Affinity Chromatography, Ashley G. Woolfork, David S. Hage

Department of Chemistry: Dissertations, Theses, and Student Research

High performance affinity chromatography (HPAC) was used in a zonal competition format to investigate the overall binding of two sulfonylurea drugs with modified human serum albumin (HSA). The in vitro modifications of this protein that were examined included glycation, as occurs in the presence of elevated glucose levels during diabetes, and the formation of advanced glycation end-products (AGEs) due to the reaction of HSA with methylglyoxal (MGo). The sulfonylurea drugs acetohexamide and tolbutamide, which are used to treat type II diabetes, were each injected onto 10 mm x 2.1 mm i.d. affinity microcolumns that contained normal HSA and HSA modified …

Improvement Of Low Traffic Volume Gravel Roads In Nebraska, Richard L. Wood, Yong-Rak Kim, Yijun Liao, Mohammad E. Mohammadi

Nebraska Department of Transportation: Research Reports

In the state of Nebraska, over one-third of roadways are unpaved, and consequently require a significant amount of financial and operational resources to maintain their operation. Undesired behavior of surface gravel aggregates and the road surfaces can include rutting, corrugation, and ponding that may lead to reduced driving safety, speed or network efficiency, and fuel economy. This study evaluates the parameters that characterize the performance and condition of gravel roads overtime period related to various aggregate mix designs. The parameters, including width, slope, and crown profiles, are examples of performance criteria. As remote sensing technologies have advanced in the recent …

Synthesis Of Repair Practices Of Damaged Precast/Prestressed Concrete Girders, George Morcous, Richard L. Wood, Antony Mohsen Kamal Masoud Kodsy

Nebraska Department of Transportation: Research Reports

Bridge girders are constantly subjected to various types of damage during their service life. There is currently limited knowledge or guidelines provided by the NDOT Bridge Office Policies and Procedures (BOPP) regarding the assessment and repair procedures of damaged precast/prestressed concrete girders. This report aims to develop a comprehensive repair manual for precast/prestressed concrete girders subjected to damage caused by over-height vehicular collision and damage located at the girder ends. Over-height vehicular collision damage typically occurs at the middle portion of the exterior girders and the primary concerns are focused on flexural deficiencies. Girder end damage can occur due to …

“My Name Is My Identity”: Understanding Conceptualizations Of Gender Identity To Improve Measurement, Sage Volk

Honors Program: Senior Projects (Public)

Existing measures of gender identity have some inconsistencies that lead to researchers missing out on the comprehensive image of an individual’s gender. The purpose of the present study was to assess how individuals who do not identify with the gender assigned to them at birth conceptualize their gender identity. To understand which aspects are important to an individual’s gender identity, semi-structured interviews were conducted with four undergraduate students who identified as non-cisgender (e.g., transgender, non-binary, genderqueer, etc.). Results of the qualitative analysis identified two themes within conceptualizations of gender identity: (1) personal and (2) social. The importance of these …

Typically Developing Preschoolers’ Behavior Toward Peers With Disabilities In Inclusive Classroom Contexts, Soo-Young Hong, Jungwon Eum, Yanjie Long, Chaorong Wu, Greg Welch

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

This study aimed to investigate typically developing preschoolers’ behavior toward peers with disabilities in inclusive classrooms, focusing on the co-occurrence of the interactions between children with and without disabilities with various classroom contexts. Behaviors of 22 typically developing preschoolers were observed and coded on two different days in both indoor and outdoor classrooms during free play, small group activities, transitions, and meals/snack. Typically developing children interacted with peers with disabilities for a small amount of time; the interactions were significantly more likely in the outdoor classroom, in either child- or teacher-directed activities, and in play activities. There was a lack …

Sex Bias In Gut Microbiome Transmission In Newly Paired Marmosets (Callithrix Jacchus), Lifeng Zhu, Jonathan B. Clayton, Mallory J. Suhr Van Haute, Qinnan Yang, Haley R. Hassenstab, Aaryn C. Mustoe, Dan Knights, Andrew K. Benson, Jeffrey A. French

Department of Food Science and Technology: Faculty Publications

Social behavior can alter the microbiome composition via transmission among social partners, but there have been few controlled experimental studies of gut microbiome transmission among social partners in primates. We collected longitudinal fecal samples from eight unrelated male-female pairs of marmoset monkeys prior to pairing and for 8 weeks following pairing. We then sequenced 16S rRNA to characterize the changes in the gut microbiome that resulted from the pairing. Marmoset pairs had a higher similarity in gut microbiome communities after pairing than before pairing. We discovered sex differences in the degrees of change in gut microbiome communities following pairing. Specifically, …

An Examination Of Nebraska’S Law Setting The Age Of Majority At Nineteen, Lauren Mcneal

Honors Program: Senior Projects (Public)

My proposed research covers the actions of the Nebraska legislature surrounding the age of majority. During the summer of 2019, I interned with Senator Adam Morfeld to draft a bill lowering the age of majority in Nebraska from nineteen to eighteen for healthcare services. Many eighteen-year-olds, especially students, face complications when they seek healthcare services but need parental consent. This is because young adults tend to move away from their homes at this age but are still not considered independent from their parents under Nebraska state law. In this thesis, I use the information I gathered from my interim research …

Effects Of Inactivated Mycobacterium Bovis Vaccination On Molokai-Origin Wild Pigs Experimentally Infected With Virulent M. Bovis, Pauline Nol, Morgan Wehte, Richard A. Bowen, Suelee Robbe-Austerman, Tyler Thacker, Kristina Lantz, Jack Rhyan, Laurie A. Baeten, Ramón A. Juste, Iker A. Sevilla, Christian Gortazar, Joaquín Vicente

United States Department of Agriculture Wildlife Services: Staff Publications

The wild pig population on Molokai, Hawaii, USA is a possible reservoir for bovine tuberculosis, caused by Mycobacterium bovis, and has been implicated in decades past as the source of disease for the island’s domestic cattle. Heat-inactivated vaccines have been effective for reducing disease prevalence in wild boar in Spain and could prove useful for managing M. bovis in Molokai wild pigs. We designed an experiment to test this vaccine in wild pigs of Molokai genetics. Fifteen 3–4-month-old pigs were orally administered 10⁶–10⁷ colony forming units (cfu) of heat-inactivated M. bovis (Vaccinates; n = 8; 0.2 …
