School of Natural Resources: Faculty Publications

Copious use of antibiotics in aquaculture farming systems has resulted in surface water contamination in some countries. Our objective was to develop a slow-release oxidant that could be used in situ to reduce antibiotic concentrations in discharges from aquaculture lagoons. We accomplished this by generating a slow-release permanganate (SR-MnO₄^-) that was composed of a biodegradable wax and a phosphate-based dispersing agent. Sulfadimethoxine (SDM) and its synergistic antibiotics were used as representative surrogates. Kinetic experiments verified that the antibiotic-MnO₄^- reactions were first-order with respect to MnO₄^- and initial antibiotic concentration (second-order rates: 0.056–0.128 s …

Daugherty Water for Food Global Institute: Faculty Publications

Climate change has brought increasing attention to the assessment of health risks associated with climate and extreme events. Drought is a complex climate phenomenon that has been increasing in frequency and severity both locally and globally due to climate change. However, the health risks of drought are often overlooked, especially in places such as the United States, as the pathways to health impacts are complex and indirect. This study aims to conduct a comprehensive assessment of the effects of monthly drought exposure on respiratory mortality for NOAA climate regions in the United States from 2000 to 2018. A two-stage model …

The Unintended Consequences Of China’S One-Child Policy, E. Wesley F. Peterson

Cornhusker Economics

In 1968, Paul Ehrlich published a book entitled The Population Bomb in which he argued that rapid population growth would overwhelm the world’s capacity to feed, house, and otherwise care for the coming millions of people. At that time, the world population was about 3.5 billion growing at an average annual rate of 2.06 percent (World Bank 2023). At that rate of growth, the world’s population would have been expected to double to 7.0 billion by 2001. In fact, population growth rates fell after the 1960s and world population reached only 6.2 billion in that year. Fears of a population …

Hematopoietic Stem Cells And Betaherpesvirus Latency, Lindsey B. Crawford

Department of Biochemistry: Faculty Publications

The human betaherpesviruses including human cytomegalovirus (HCMV), human herpesvirus (HHV)-6a and HHV-6b, and HHV-7 infect and establish latency in CD34+ hematopoietic stem and progenitor cells (HPCs). The diverse repertoire of HPCs in humans and the complex interactions between these viruses and host HPCs regulate the viral lifecycle, including latency. Precise manipulation of host and viral factors contribute to preferential maintenance of the viral genome, increased host cell survival, and specific manipulation of the cellular environment including suppression of neighboring cells and immune control. The dynamic control of these processes by the virus regulate inter- and intra-host signals critical to the …

Basic Fibroblast Growth Factor Induces Proliferation And Collagen Production By Fibroblasts Derived From The Bovine Corpus Luteum, Corrine F. Monaco, Michele R. Plewes, Emilia Przygrodzka, Jitu W. George, Fang Qiu, Peng Xiao, Jennifer R. Wood, Andrea S. Cupp, John S. Davis

Department of Animal Science: Faculty Publications

Cyclic regression of the ovarian corpus luteum, the endocrine gland responsible for progesterone production, involves rapid matrix remodeling. Despite fibroblasts in other systems being known for producing and maintaining extracellular matrix, little is known about fibroblasts in the functional or regressing corpus luteum. Vast transcriptomic changes occur in the regressing corpus luteum, among which are reduced levels of vascular endothelial growth factor A (VEGFA) and increased expression of fibroblast growth factor 2 (FGF2) after 4 and 12 h of induced regression, when progesterone is declining and the microvasculature is destabilizing. We hypothesized that FGF2 activates luteal …

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 …

Coparenting Support In The Context Of Difficult Children: Mother And Father Differences, Victoria J. Johnson, Dongho Choi, Lorey A. Wheeler, Patty X. Kuo

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

While parenting children with difficult behaviors can intensify stress within the entire family system, families may lean on other familial relationships to mitigate that stress. The coparenting relationship is known to play a key role within the family system for child outcomes and familial interactions, but it is not clear whether it eases the stress and challenge of raising a difficult child, nor how that plays out differently for mothers versus fathers. Ninety-six couples (89.7% married) parenting young children (Mean age = 3.22 years) were included in this study. Using cross-sectional and aggregated daily response data, actor–partner interdependence models were …

Next-Generation Sequencing Data-Based Association Testing Of A Group Of Genetic Markers For Complex Responses Using A Generalized Linear Model Framework, Zheng Xu, Song Yan, Cong Wu, Qing Duan, Sixia Chen, Yun Li

School of Computing: Faculty Publications

To study the relationship between genetic variants and phenotypes, association testing is adopted; however, most association studies are conducted by genotype-based testing. Testing methods based on next-generation sequencing (NGS) data without genotype calling demonstrate an advantage over testing methods based on genotypes in the scenarios when genotype estimation is not accurate. Our objective was to develop NGS data-based methods for association studies to fill the gap in the literature. Single-variant testing methods based on NGS data have been proposed, including our previously proposed single-variant NGS data-based testing method, i.e., UNC combo method. The NGS data-based group testing method has been …

The Impact Of Leadership Turnover On Child Welfare Workforce Initiatives, Courtney Harrison, Megan Paul

QIC-Takes

Turnover among public child welfare leaders is prevalent. Across the eight QIC-WD intervention sites, leadership turnover was one of the most common implementation challenges observed by the QIC-WD team. Leadership changes can disrupt the implementation of a workforce initiative by shifting agency-level priorities, the organizational climate, or key staff.

Child welfare leaders may be appointed or hired in many different ways in different jurisdictions. In some states, the Governor appoints a cabinet-level child welfare director who oversees a stand-alone agency. This means that child welfare leadership changes follow the political election cycle with new governors appointing new agency leaders every …

Expanding State Parent Registry Laws, Jeffrey A. Parness

Nebraska Law Review

As with state recognized voluntary acknowledgements of parentage (VAPs) and state recognized assisted reproduction pacts (SRARPs) on childcare parentage for future or current children, state parent registries (PRs), often labeled putative paternity registries or putative father registries, embody declarations of expecting or current legal parenthood.1 Yet declarations on children in PRs often involve unilateral assertions, unlike dual parenthood declarations in VAPs. Actual parenthood under law for many PR declarants is never recognized because there are no simultaneous assertions by a second expecting or existing legal parent on the declarant’s parenthood, as with an assertion by an expecting or existing birth …

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 …

Physician Aid In Dying: Physician-Assisted Suicide As A Constitutionally Protected Liberty Interest Under The Nebraska Constitution, Emily Newcomb

Nebraska Law Review

“Every life is different from any that has gone before it, and so is every death.”1 Although advancements in technology and healthcare have saved and prolonged countless lives, there is one part of humanity that can never be fully cured: death. Death is not what it used to be—it is no longer normally a common, family communal, or even religious event.2 Modern dying takes place in a hospital while attached to machines that attempt to prolong life but seem to simultaneously take patients further and further away from dying with dignity. As these technologies that prolong life evolve, so do …

Sparks, Hilary M. Swain, Xiangming Xiao, Jean L. Steiner

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Intensification, the process of intensifying land management to enhance agricultural goods, results in “intensive” pastures that are planted with productive grasses and fertilized. These intensive pastures provide essential ecosystem services, including forage production for livestock. Understanding the synergies and tradeoffs of pasture intensification on the delivery of services across climatic regions is crucial to shape policies and incentives for better management of natural resources. Here, we investigated how grassland intensification affects key components of provisioning (forage productivity and quality), supporting (plant diversity) and regulating services (CO2 and CH4 fluxes) by comparing these services between intensive versus extensive pastures in subtropical …

Do Cover Crop Mixtures Improve Soil Physical Health More Than Monocultures?, Humberto Blanco-Canqui

Department of Agronomy and Horticulture: Faculty Publications

Rationale and Purpose — Adding multispecies cover crop (CC) mixtures could diversify the current simplified crop rotations and enhance soil health more than monoculture CCs. Further, CC mixtures with diverse plant species could adapt better to changing climatic and environmental conditions than monoculture CCs. However, our current understanding of the soil benefits of CC mixtures is still limited. This review discussed whether CC mixtures are better than monoculture CCs to improve soil physical health.

Methods — All studies published up to May 25, 2023, comparing soil physical properties between CC mixtures and their constituents grown as monocultures were searched in …
