To gain insights into the challenges faced by Nebraska farmers and landowners when adopting precision agriculture technologies, I analyzed data collected from a 2022 survey involving 7,503 participants, consisting of producers and farmland owners from across the state of Nebraska. The primary objective was to provide valuable insights for agencies seeking to improve their precision agriculture and conservation outreach efforts for the benefit of conservation and Nebraskan farmers and landowners. This study aimed to understand key factors influencing adoption behaviors by evaluating the constraints to precision agriculture adoption, assessing the impact of producer and landowner …

Assessing Determinants Of Participation In Conservation Programs In The U. S., Manita Ale

Department of Agricultural Economics: Dissertations, Theses, and Student Research

The United States Department of Agriculture (USDA) has implemented conservation programs through Natural Resources Conservation Service (NRCS) and Farm Service Agency (FSA). Conservation Reserve Program (CRP), Conservation Stewardship Program (CSP), and Environmental Quality Incentives Program (EQIP) are some of them. These programs provide financial and technical assistance to farmers and ranchers to adopt land management practices that generate environmental benefits. In this study, we explore the determinants of participation in conservation programs (CRP, CSP, EQIP) in Iowa, Kansas, and Nebraska. For this, we use a unique survey-based data set comprising observations from row crop farmers in these states. We are …

Animal Welfare Deserts: Human And Nonhuman Animal Inequities, Laura Reese, Xiaomeng Li

School of Global Integrative Studies: Faculty Publications

Residents of distressed areas of inner cities have less access to many of life’s necessities and amenities than their more well-off counterparts. Geographic proximity has been identified as a primary barrier to accessing care for pets potentially creating animal welfare deserts. This project addresses three questions: Are there visible animal welfare deserts in distressed urban centers?; What human inequities are most strongly related to animal welfare deserts?; and What might be done to address these inequities? Using business location and census data in the city of Detroit, this research identifies distinct animal welfare deserts finding that more prosperous areas have …

Assessing The Impact Of Spatial Resolution Of Uas-Based Remote Sensing And Spectral Resolution Of Proximal Sensing On Crop Nitrogen Retrieval Accuracy, Kianoosh Hassani, Hamed Gholizadeh, Saleh Taghvaeian, Victoria Natalie, Jonathan Carpenter, Jamey Jacob

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Foliar nitrogen (N) plays a central role in photosynthetic machinery of plants, regulating their growth rates. However, field-based methods for monitoring plant N concentration are costly and limited in their ability to cover large spatial extents. In this study, we had two objectives: (1) assess the capability of unoccupied aerial system (UAS) and non-imaging spectroscopic data in estimating sorghum and corn N concentration and (2) determine the impact of spatial and spectral resolution of reflectance data on estimating sorghum and corn N concentration. We used a UAS and an ASD spectroradiometer to collect canopy- and leaf-level spectral data from sorghum …

Harvestable Metadata Services Development: Analysis Of Use Cases From The World Data System, Robert R. Downs, Alicia Urquidi Díaz, Qi Xu, Juanle Wang, Aude Chambodut, Chuang Liu, Simon Flower, Karen Payne

Copyright, Fair Use, Scholarly Communication, etc.

Minimally, a research data repository exists to make a collection of data assets available to potential users. If a dataset cannot be discovered and found, it cannot be reused (Garnett et al. 2017). Harvestable metadata catalogues are a key strategy for achieving greater global findability of data assets, as they create a surveyable access point to discover data products within large data collections. Such catalogues can be especially effective if they are tailored for interoperability with feature-rich infrastructures (e.g. meta-catalogues, see Kapiszewski & Karcher 2020; CRFCB 2014) that are highly visible and widely used, and also themselves integrated within the …

Coverage Error Properties Of Smartphone And Smartphone Operating System Ownership On Web Surveys: A Total Survey Error Perspective, Angelica Phillips

Department of Sociology: Dissertations, Theses, and Student Research

While smartphone ownership rates near 90% of the US population, differences in the types of people who do or do not own smartphones may contribute to coverage error biases within smartphone-exclusive web surveys. Therefore, understanding the predictors of smartphone ownership is of interest for survey researchers. Further, differential ownership of smartphone operating systems (OS) such as Android OS and iOS across groups of the population is also of interest for researchers who administer smartphone application surveys which are only compatible with one OS. However, little research has assessed differential rates of smartphone ownership over time nor has any research to …

Arthropod Diversity In Phytotelmata Of Calathea Capitata (Zingiberales; Marantaceae) Host Plants From Peru, Divya Dendi, Timo Förster, Caroline S. Chaboo

Department of Entomology: Faculty Publications

Cryptic habitats are often overlooked in biodiversity surveys. Phytotelmata, or plant pools, are one type of cryptic habitat that supports diverse fauna in a miniature ecosystem. This study surveys the arthropod community of two types of phytotelmata, bracts and leaf rolls, on a single species, Calathea capitata (Ruiz and Pav.) Lindl. (Zingiberales: Marantaceae), from one Amazon site in Peru. Specimens were collected from eight bracts and eight leaf rolls. A total of 55 arthropods (36 adults, 19 juveniles) were found in both phytotelmata types. In the bract samples were found: spiders (Araneae: Corinnidae), beetles (Coleoptera: Carabidae, Erotylidae, Staphylindae), flies (Diptera: …

Quantitative Risk Assessment Of Oocyst Versus Bradyzoite Foodborne Transmission Of Toxoplasma Gondii In Brazil, Sophie Zhu, Elizabeth Vanwormer, Beatriz Martínez-López, Lílian Maria Garcia Bahia-Oliveira, Renato Augusto Damatta, Pedro Souto Rodrigues, Karen Shapiro

School of Veterinary and Biomedical Sciences: Faculty Publications

Toxoplasma gondii is a globally distributed zoonotic protozoan parasite. Infection with T. gondii can cause congenital toxoplasmosis in developing fetuses and acute outbreaks in the general population, and the disease burden is especially high in South America. Prior studies found that the environmental stage of T. gondii, oocysts, is an important source of infection in Brazil; however, no studies have quantified this risk relative to other parasite stages. We developed a Bayesian quantitative risk assessment (QRA) to estimate the relative attribution of the two primary parasite stages (bradyzoite and oocyst) that can be transmitted in foods to people in …

The Complete Mitochondrial Genome Of Eulaelaps Huzhuensis (Mesostigmata: Haemogamasidae), Hui-Juan Yang, Zhi-Hua Yang, Tian-Guang Ren, Wen-Ge Dong

Harold W. Manter Laboratory of Parasitology: Library Materials

Some mites of the family Haemogamasidae can transmit a variety of zoonotic diseases and have important public health and safety implications. Currently, however, little attention has been paid to molecular data of Haemogamasidae species, limiting our understanding of their evolutionary and phylogenetic relationships. In this study, the complete mitochondrial genome of Eulaelaps huzhuensis was determined for the first time, and its genomic information was analyzed in detail. The mitochondrial genome of E. huzhuensis is 14,872 bp in length with 37 genes and two control regions. The base composition showed a distinct AT preference. Twelve protein-coding genes have a typical ATN …

Defining Open Scholarly Infrastructure: A Review Of Relevant Literature, Saman Goudarzi, Richard Dunks

Copyright, Fair Use, Scholarly Communication, etc.

This report outlines IOI’s initial attempt towards a framework for understanding open infrastructure for research and scholarship. For this report, we examined a body of literature that includes works across the fields of anthropology, scholarly communications, international development studies, science and technology studies, and infrastructure studies. ....

This review also makes clear that the distinguishing feature between open infrastructure and its commercially-run and -operated counterparts is the fact that its value lies not just in its ability to support productive functions but how it fosters positive and desirable social practices and values. It is insufficient to simply assert certain values …

“I Don’T Want To Die”: A Qualitative Study Of Coping Strategies To Prevent Fentanyl‑Related Overdose Deaths Among People Who Inject Drugs And Its Implications For Harm Reduction Policies, Roberto Abadie

Department of Sociology: Faculty Publications

Background Fentanyl and fentanyl-related analogues are the main drivers of overdose death in the USA, particularly among people who inject drugs (PWID). Despite the fact that non-Hispanic whites exhibit higher population rates of synthetic opioid mortality, overdose deaths have increased among African American and Latinos in urban areas. Yet little attention has been paid to the introduction of fentanyl among rural PWID in Puerto Rico.

Methods We conducted N = 38 in-depth interviews with PWID in rural Puerto Rico to document participants’ experiences of injection drug use after the arrival of fentanyl and the strategies they implemented to manage overdose …

Addressing Secondary Traumatic Stress, Burnout, Resilience And Turnover In The Child Welfare Workforce: Results From A 6-Month, Cluster-Randomized Control Trial Of Resilience Alliance, Rebecca Orsi-Hunt, Courtney L. Harrison, Kayla E. Rockwell, Anita P. Barbee

QIC-WD Journal Articles

Introduction: US child welfare agencies have historically struggled with workforce retention and turnover. As part of the Quality Improvement Center for Workforce Development in Child Welfare, we tested an adaptation of the Resilience Alliance (RA) model in a large, Midwestern state to address workplace stress, burnout and actual workforce turnover. RA is a 24-week, facilitated program designed to mitigate the impact of secondary traumatic stress among child welfare professionals, and to therefore increase job satisfaction, resilience and optimism and to decrease turnover, stress reactivity and burnout.

Methods: Supervisory units of caseworkers and supervisors were randomized to the RA treatment …

Incentivizing Electric Vehicle Adoption Through State And Federal Policies: Reviewing Influential Policies, Joshua Sabata, Subhaditya Shom, Ahmad Almaghrebi, Anne Mccollister, Mahmoud Alahmad

Durham School of Architectural Engineering and Construction: Faculty Publications

All-electric vehicles (EVs), battery-powered EVs (BEVs), and plug-in hybrid EVs (PHEVS) are gaining market share and increasing in popularity with the buying public because the battery range (longer) and cost (lower) have reached sweet spots, the charging infrastructure is more robust, and concern with global cli­mate change is high. In 2013, only 100,000 EVs were sold in the United States, but by 2022, approximately 800,000 have been purchased. A similar growth is seen in EV sup­ply equipment (EVSE), i.e., EV charging stations, with 19,742 documented EV charging station locations in the United States in 2013 to 50,054 documented EV charging …

Toxicological Effects Assessment For Wildlife In The 21st Century: Review Of Current Methods And Recommendations For A Path Forward, Thomas G. Bean, Val R. Beasley, Philippe Berny, Karen M. Eisenreich, John E. Elliott, Margaret L. Eng, Phyllis C. Fuchsman, Mark S. Johnson, Mason D. King, Rafael Mateo, Carolyn B. Meyer, Christopher J. Salice, Barnett A. Rattner

United States Geological Survey: Staff Publications

Model species (e.g., granivorous gamebirds, waterfowl, passerines, domesticated rodents) have been used for decades in guideline laboratory tests to generate survival, growth, and reproductive data for prospective ecological risk assessments (ERAs) for birds and mammals, while officially adopted risk assessment schemes for amphibians and reptiles do not exist. There are recognized shortcomings of current in vivo methods as well as uncertainty around the extent to which species with different life histories (e.g., terrestrial amphibians, reptiles, bats) than these commonly used models are protected by existing ERA frameworks. Approaches other than validating additional animal models for testing are being developed, but …

Measuring Diversity, Equity, And Inclusion, Quality Improvement Center For Workforce Development

Workforce Analytics Resources

What is Diversity?

Diversity refers to the degree of differences in the composition of the workforce in terms of such constructs as race, ethnicity, gender, gender identity and expression, sexual orientation, religion, disability, age, national origin, language, or other social identities. Though there are certainly other types of employee differences worth assessing (e.g., acquired diversity characteristics, such as education, skills, personality, preferences, attitudes), the focus here is on inherent social identities, especially those that are related to differences in representation, power, and privilege. Note that diversity is a characteristic of a group, not an individual.

How is Diversity Measured?

Occurrence Of Radionuclides And Hazardous Elements In The Transboundary River Basin Kyrgyzstan–Kazakhstan, Mariya A. Severinenko, Vladimir P. Solodukhin, Bekmamat M. Djenbaev, The National Academy Of Science Of The Kyrgyz Republic G. Lennik, Baktiyar T. Zholboldiev, Daniel D. Snow

Nebraska Water Center: Faculty Publications

Important for irrigation, the transboundary river basin between Kyrgyzstan and Kazakhstan is vulnerable to geochemical and anthropogenic sources of pollution. The use of water use indices, together with measurements of the elemental and radionuclide composition of the water and bottom sediments, provides a means for evaluating the continued use of the water from this region. Recent monitoring shows the highest concentrations of hazardous contaminants include lead and thorium contained in the bottom and banks of the Kichi-Kemin River. These contaminants are likely remnants of an accidental spill at the Aktyuz tailing dump in 1964. The specific activity of the Th-232 …

Nebraska’S Medico-Legal System: A Death Investigation Analysis, Ashley Novak

Honors Program: Senior Projects (Public)

A large part of the founding of the United States of America focused on the idea of state control over their internal affairs. For this reason, the United States is home to a largely decentralized medico-legal system. The State of Nebraska hosts a coroner-based death investigation system as is written into their legislation regarding the establishment of their medico-legal system. By studying legislation, federal and state reports, as well as publications by academics within the field, merits and weaknesses of the Nebraskan coroner system can be uncovered. Additional considerations and understandings that are needed to be understood include: understanding what …

Student Perspectives Of Sustainable Transportation Use On A College Campus, Brynn Fuelberth

Department of Environmental Studies: Undergraduate Student Theses

As climate change grows in relevance in society, attention has often been turned to large universities to look at what solutions can help minimize the impacts contributing to the devastation. Sustainable transportation is an alternative that can help combat these issues. This study specifically focuses on what sustainable transportation looks like at the University of Nebraska-Lincoln (UNL), and what barriers and motivations are present in the undergraduate students’ eyes. This was investigated through an open-ended qualitative survey administered to the undergraduate population of the UNL. This study asks how students make their mode decisions in relation to sustainable transportation methods, …

Plasticity Of Sorghum Biomass And Inflorescence Traits In Response To Nitrogen Application, Kyle M. Linders

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

Nitrogen is an essential nutrient required for growth and development in plants. Insufficient nitrogen availability can reduce vegetative growth and grain yield. However, nitrogen is a costly input for farmers, is energy intensive to manufacture, and runoff of excess nitrogen fertilizer impacts water quality. Compared to its close relative, maize, sorghum has much greater resilience to nitrogen and water deficit, and heat stress, allowing sorghum to be grown with fewer inputs and on marginal land. Variation in total biomass accumulation and grain yield between sorghum accessions, as well as between nitrogen conditions, can be largely explained by differences in vegetative …

County Finance, House Prices, And Financial Decision-Making, Kyle Kopplin

College of Business: Dissertations, Theses, and Student Research

This work is in three chapters. The first chapter investigates the extent to which county-level property tax changes are capitalized into house prices. The literature mainly focuses on specific tax events, but this chapter generalizes the context to large U.S. cities. The main findings suggest that county-level property tax capitalization occurs and varies along the distribution of house prices. The second chapter measures differences in county-aggregated self-assessed valuations of house prices and county- aggregated sale prices to determine whether there are trends in the level of misperceived house value. Factors like age, time of tenure in a house, and house …

An Exploration Of Influences On Consumers' Behaviors/Decisions In Relation To Animal Agriculture, Abigail Durheim

Department of Agricultural Leadership, Education, and Communication: Dissertations, Theses, and Student Research

Animal agriculture provides many daily resources for consumers around the globe. While the average American is at least three generations removed from agriculture, they still hold power to influence the industry with the dollar and their vote. The purpose of this study was to identify influences on consumer behaviors/decisions in relation to animal agriculture. Seven hundred four complete and usable responses were collected via a researcher-developed online survey. Using branding concepts as a framework, the first study evaluated how visual stimuli influenced consumers' intention to purchase Nebraska beef products. Researchers found that visual stimuli did influence respondents to choose Nebraska …

The Effects Of Telehealth On Access To Palliative Care In Rural Communities, Ryleigh Hanson

Honors Program: Senior Projects (Public)

Patients with serious and life-limiting illnesses are in need of palliative care which allows for both the patient and their family to learn how to live a relatively quality life in spite of their illness. Current access to palliative care is limited to urban areas leaving those in rural communities to face their illness without proper care. To understand why these limitations exist and to determine possible solutions, several articles were analyzed that focused on the benefits and stigmas of palliative care, why rural communities struggle to gain access to palliative care, and if telehealth is a possible solution to …

Analyzing Sea Level Rise Adaptation And Mitigation Strategies In Louisiana And The Netherlands, Jonah Mcdowell

Department of Environmental Studies: Undergraduate Student Theses

Sea level rise is an increasingly dangerous threat. As a byproduct of climate change, this is an issue that has the potential to impact countless people, animals, and ecosystems across the globe. As sea level rise continues to worsen, it is imperative that coastal communities develop their own strategies and plans to combat this problem. This study focuses on two areas, the state of Louisiana and the country of the Netherlands, and studies how they have responded to this problem. These locations were chosen because sea level rise is proportionally more severe at these two locations compared to other areas …

Unemployment And Opioid-Related Mortality Rates In U.S. Counties: Investigating Social Capital And Social Isolation–Smoking Pathways, Tse-Chuan Yang, Seulki Kim, Stephen A. Matthews

Department of Sociology: Faculty Publications

We examine two mechanisms—social capital and sociobehavior—potentially linking unemployment rates to opioid-related mortality and investigate whether the mechanisms differ geographically by the pace of the opioid crisis. Applying path analysis techniques to 2015–2017 opioid-related mortality in U.S. counties (N = 2,648), we find that (1) high unemployment rates are not directly associated with opioid-related mortality rates; (2) high unemployment rates are negatively associated with social capital, and low social capital contributes to high opioid-related mortality; (3) high unemployment rates increase social isolation and the prevalence of smoking, which is positively related to opioid-related mortality; and (4) the pathways are stronger …

Riodinid Butterfly Fauna (Lepidoptera) Of The Cosñipata Region, Peru: Annotated Checklist, Community Structure, And Contrast With Lycaenidae, Gerardo Lamas, Jon D. Turner, Michael L. Mcinnis, Robert K. Robbins

Insecta Mundi

A team of experienced lepidopterists sampled the butterfly fauna of Peru’s Cosñipata Region from 400 to 4,000 m elevation for more than a decade (7,440 field person-hours) and supplemented this sam­ple with data from museum specimens and the scientific literature. An annotated checklist of Cosñipata Riodinidae (Lepidoptera: Papilionoidea) documents 398 species, which represents 29% of the world Rio­dinidae fauna. For each, it lists sample abundance, adult behavior, elevation, and temporal distribution. In the fieldwork sample, 75 species (20.9%) were sampled once and 39 (9.8%) were not encountered (collected or imaged by others). A riodinid species of median abundance was sampled …

Improving Nasa’S Earth Satellite And Model Data Discoverability For Interdisciplinary Research, Applications, And Education, Zhong Liu, Chung-Lin Shie, Suhung Shen, James Acker, Angela Li, Jennifer C. Wei, David J. Meyer

Copyright, Fair Use, Scholarly Communication, etc.

Since the Internet era began, numerous earth science data services have been developed to facilitate data discovery (for example, data sources, documents, facts, visualization, opinions) and data access for research and application activities. For example, a large collection of NASA’s earth science data has been made searchable and freely downloadable over the Internet. Some value-added services even allow users to analyze and visualize many variables online (for example, 2,000+ in NASA Giovanni) without downloading data and software.

However, finding and discovering suitable datasets and information for interdisciplinary research (involving two or more scientific disciplines), applications, education, and other emerging activities …
