Practice Cost And Size Differences In Invasive Plant Management Strategies: An Empirical Analysis Of Us Great Plains States, Mazbahul G. Ahamad

Department of Agronomy and Horticulture: Faculty Publications

Grassland conservation of the Conservation Stewardship Program in the United States (US) is one of the largest cost-sharing initiatives for protecting grazing land from invasive and woody plants. The practice cost and unit size of various invasive and woody plant management strategies, such as mulching, brush management, and pre- scribed burning, are different from state to state. We aimed to compare and examine the association between practice cost ($/acre[ac]) and standard unit size of practice (acre) of mulching, brush management, and pre- scribed burning strategies in nine US Great Plains states, including Kansas, Montana, Nebraska, New Mexico, North Dakota, Oklahoma, …

Transformation Of Major Peanut (Arachis Hypogaea) Stilbenoid Phytoalexins Caused By Selected Microorganisms, Victor S. Sobolev, Travis E. Walk, Renee S. Arias, Alicia N. Massa, Valerie A. Orner, Marshall C. Lamb

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

The peanut plant accumulates defensive stilbenoid phytoalexins in response to the presence of soil fungi, which in turn produce phytoalexin-detoxifying enzymes for successfully invading the plant host. Aspergillus spp. are opportunistic pathogens that invade peanut seeds; most common fungal species often produce highly carcinogenic aflatoxins. The purpose of the present research was to evaluate the in vitro dynamics of peanut phytoalexin transformation/detoxification by important fungal species. This work revealed that in feeding experiments, Aspergillus spp. from section Flavi were capable of degrading the major peanut phytoalexin, arachidin-3, into its hydroxylated homolog, arachidin-1, and a benzenoid, SB-1. However, Aspergillus niger from …

An Efficient Method Of Evaluating Multiple Concurrent Management Actions On Invasive Populations, Amy J. Davis, Randy Farrar, Brad Jump, Parker Hall, Travis Guerrant, Kim M. Pepin

United States Department of Agriculture Wildlife Services: Staff Publications

Evaluating the efficacy of management actions to control invasive species is crucial for maintaining funding and to provide feedback for the continual improvement of management efforts. However, it is often difficult to assess the efficacy of control methods due to limited resources for monitoring. Managers may view effort on monitoring as effort taken away from performing management actions. We developed a method to estimate invasive species abundance, evaluate management effectiveness, and evaluate population growth over time from a combination of removal activities (e.g., trapping, ground shooting) using only data collected during removal efforts (method of removal, date, location, number of …

Lifelong Effects Of Poverty, Jill Mccaslin-Timmons, Marilyn Grady

Journal of Women in Educational Leadership

Poverty in the United States impacts children in public schools. In reviewing the literature on poverty, several themes emerged. The themes included: the struggle to define poverty in the United States, characteristics of families in poverty, the impact of poverty on school and lifelong effects of poverty on children.

Additionally, a personal story of a public school administrator who grew up in poverty is shared. This includes how the impact of that experience still impacts the way she thinks about poverty and interacts with families from poverty.

The False Dichotomy Of Sex And Religion In America, Kelsy Burke

Department of Sociology: Faculty Publications

Religion and sexuality are polysemic categories. While conservative religion often fights against progressive sexual politics in contemporary America, this “usual story” is fractured and destabilized by people navigating the relationship between religion and sexuality as complex social creatures, not pundits or caricatures. Drawing from interdisciplinary scholarship, I examine salient issues of sexual politics—including abortion and reproductive rights, LGBT rights, and pornography—to show how religious actors have been on both sides of these debates. Because of this polysemic complexity, scholars of religion must not only tend to the dynamic interaction between religion and other categories, we must also recognize and study …

Economics Of Cormorant Predation On Catfish Farms, Carole Engle, Ganesh Kumar, Terrel Christie, Brian S. Dorr, Brian Davis, Luke Roy, Anita Kelly

United States Department of Agriculture Wildlife Services: Staff Publications

The Double-crested Cormorant is the primary avian predator on catfish farms causing significant economic losses primarily due to 1) on-farm expenditures related to bird-management activities and 2) value of the catfish lost to cormorants. This comprehensive economic study quantified these two economic effects by surveying catfish farms in the delta regions of Mississippi and Arkansas. On-farm expenditures for bird scaring were used to quantify bird-management costs. Economic losses from fish consumed by cormorants were quantified by evaluating data from field studies of the abundance, distribution, and diet of cormorants in the Mississippi delta. This study found that catfish farmers …

Two Heads Are Better Than One: Current Landscape Of Integrating Qsp And Machine Learning, Tongli Zhang, Ioannis P. Androulakis, Peter Bonate, Limei Cheng, Tomáš Helikar, Jaimit Parikh, Christopher Rackauckas, Kalyanasundaram Subramanian, Carolyn R. Cho

Department of Biochemistry: Faculty Publications

Quantitative systems pharmacology (QSP) modeling is applied to address essential questions in drug development, such as the mechanism of action of a therapeutic agent and the progression of disease. Meanwhile, machine learning (ML) approaches also contribute to answering these questions via the analysis of multi-layer ‘omics’ data such as gene expression, proteomics, metabolomics, and high-throughput imaging. Furthermore, ML approaches can also be applied to aspects of QSP modeling. Both approaches are powerful tools and there is considerable interest in integrating QSP modeling and ML. So far, a few successful implementations have been carried out from which we have learned about …

Other QIC-WD Products

What is onboarding and why was this intervention selected?

Onboarding (also referred to organizational socialization) is “…the process by which newcomers make the transition from being organizational outsiders to being insiders” (Bauer, et al., 2007, p. 707). The overall goal of onboarding is to facilitate newcomer adjustment (Bauer & Erdogan, 2011), meaning that new employees understand the key tasks of their job (i.e., role clarity), have confidence in their ability to perform the key tasks of their job (i.e., self-efficacy), feel like they are an accepted member of the organization (i.e., social acceptance), and understand the …

Survey Of State Laws Governing Fees Associated With Late Payment Of Rent, Ryan Sullivan

Nebraska College of Law: Faculty Publications

The Survey contains both a cumulative and detailed account of the laws of each state governing late fees and penalties associated with late payment of rent involving residential tenancies. States that impose late fee maximums vary greatly on the amount and form of the limitation—some limit the late fee to a certain percentage of the rental amount, a few states impose a dollar amount maximum, and several states impose both. Some states, rather than limiting the late fee to a certain amount, only require that the late fee be “reasonable.” Additionally, a handful of states mandate that late fees can …

Water Insecurity, Water Borrowing, And Psychosocial Stress Among Daasanach Pastoralists In Northern Kenya, Leslie Ford, Hilary J. Bethancourt, Zane Swanson, Rosemary Nzunza, Amber Wutich, Alexandra Brewis, Sera Young, David Almeida, Matthew J. Douglass, Emmanuel K. Ndiema, David R. Braun, Herman Pontzer, Asher Y. Rosinger

School of Natural Resources: Faculty Publications

This article quantifies Daasanach water insecurity experiences in Northern Kenya, examines how water insecurity is associated with water borrowing and psychosocial stress, and evaluates if water borrowing mitigates the stress from water insecurity. Of 133 households interviewed in 7 communities, 95% were water insecure and 74.4% borrowed water three or more times in the prior month. Regression analyses demonstrate water borrowing frequency moderates the relationship between water insecurity and psychosocial stress. Only those who rarely or never borrowed water reported greater stress with higher water insecurity. The coping mechanism of water borrowing may help blunt water insecurity-related stress.

However, evidence indicates that excessive intake interferes with the metabolic processes of different tissues. Thus, this study aimed to investigate the effects of long-term exposure to F on the parotid salivary gland of mice, from the analysis of oxidative, proteomic and genotoxic parameters.

The animals received deionized water containing 0, 10 or 50 mg/L of F, as sodium fluoride, for 60 days. After, parotid glands were collected for analysis of oxidative biochemistry, global proteomic profile, genotoxicity assessment and histopathological analyses.

The results revealed that exposure to …

Compensation, Megan Paul

Umbrella Summaries

What is compensation?

For the purposes of this review, compensation is defined in two primary ways: a) pay and b) pay satisfaction. Pay refers to “the amount of money an individual receives for their job” (Rubenstein et al., 2017, p. 6). It is sometimes measured as the exact amount or in terms of pay levels (Judge et al., 2010). Pay satisfaction is about an employee’s feelings about their pay, either in general or in terms of more specific aspects. Depending on how it is measured, pay satisfaction often also includes feelings about benefits, which might be more appropriately called compensation …

The Social Networks Of Manureshed Management, Gwendwr Rhiannon Meredith, Sheri Spiegal, Peter J. A. Kleinman, Daren Harmel

School of Natural Resources: Faculty Publications

Manureshed management—the strategic use of manure nutrients that prioritizes recycling between livestock systems and cropping systems—provides a comprehensive framework for sustainable nutrient management that necessitates the collaboration of many actors. Understanding the social dimensions of collaboration is critical to implement the strategic and technological requirements of functional manuresheds. To improve this understanding, we identified aspirational networks of actors involved in manureshed management across local, regional, and national scales, principally in the United States, elucidating key relationships and highlighting the breadth of interactions essential to successful manureshed management. We concluded that, although the social networks vary with scale, the involvement of …

Beyond The School Walls: Collective Impact In Micropolitan School-Community Partnerships, Sarah Zuckerman

Department of Educational Administration: Faculty Publications

Research suggests that the time students spend outside of school, as well as the communities in which they spend it, impact educational outcomes. Inequitable educational outcomes are the result of complex, interdependent problems in the public and private sector, suggesting the need for approaches that bring together schools with other organizations to address problems in the ecological and developmental systems of family, school, out-of-school programs, and communities. Collective impact has gained prominence as a strategy for such cross-sector partnerships. This qualitative study uses a comparative approach to extend knowledge of collective impact into rural and micropolitan communities using civic capacity …

Preliminary Evidence That Lectins In Infant Soy Formula Apparently Bind Bovine Milk Exosomes And Prevent Their Absorption In Healthy Adults, Ezra Mutai, Alice Kah Hui Ngu, Janos Zempleni

Department of Nutrition and Health Sciences: Faculty Publications

Background: Milk exosomes and their microRNA (miR) cargos are bioavailable. The content of exosomes and miRs is negligible in infant formulas compared to human milk, and dietary depletion of exosomes led to changes in bacterial communities and impaired gut health in juvenile mice. Adverse effects of formula feeding may be compounded by using soy formulas due to exosome binding by abundant lectins in that matrix. The purpose of this study was to assess the bioavailability of milk exosomes and their miR cargos added to soy formula in adults, as well as the potential role of soy lectins in exosome …

Harnessing Mycobacterium Bovis Bcg Trained Immunity To Control Human And Bovine Babesiosis, Reginaldo G. Bastos, Heba F. Alzan, Vignesh A. Rathinasamy, Brian M. Cooke, Odir A. Dellagostin, Raul G. Barletta, Carlos E. Suarez

School of Veterinary and Biomedical Sciences: Faculty Publications

Babesiosis is a disease caused by tickborne hemoprotozoan apicomplexan parasites of the genus Babesia that negatively impacts public health and food security worldwide. Development of effective and sustainable vaccines against babesiosis is currently hindered in part by the absence of definitive host correlates of protection. Despite that, studies in Babesia microti and Babesia bovis, major causative agents of human and bovine babesiosis, respectively, suggest that early activation of innate immune responses is crucial for vertebrates to survive acute infection. Trained immunity (TI) is defined as the development of memory in vertebrate innate immune cells, allowing more efficient responses to subsequent …

Diversity And Inclusion Climates, Megan Paul

Umbrella Summaries

What are diversity and inclusion climates?

Diversity climate and inclusion climate are separate but related concepts, and there are various definitions of each. For the purposes of this review, diversity climate refers to “employees’ shared perceptions that an employer utilizes fair personnel practices and socially integrates underrepresented employees into the work environment” (McKay et al., 2008, p. 350). Inclusion climate goes one step farther to value and leverage diversity, such that “individuals of all backgrounds—not just members of historically powerful identity groups—are fairly treated, valued for who they are, and included in core decision making” (Nishii, 2013, p. 1754). A …

Relationships Between Reported Pandemic Impacts And Well-Being Of Rural Nebraskans, Rebecca J. Vogt

Cornhusker Economics

Since March of 2020, the coronavirus pandemic has impacted Nebraskans in many ways, including their physical health, mental health, work, and socialization. The 2021 Nebraska Rural Poll examined to what extent various elements of life were affected or disrupted by the pandemic as well as respondents’ general assessments of their well-being. Did rural Nebraskans’ assessments of the impacts the pandemic has had on their lives correlate with their assessment of their well-being?
