Abundance And Diversity Of Dung Beetles (Coleoptera: Scarabaeoidea) As Affected By Grazing Management In The Nebraska Sandhills Ecosystem, Patrick M. Wagner, Gandura Omar Abagandura, Martha Mamo, Thomas Weissling, Ana Wingeyer, Jeffrey D. Bradshaw

Department of Entomology: Faculty Publications

Dung beetles (Coleoptera: Scarabaeoidea) serve a significant role in regulating ecosystem services on rangelands. However, the influence of grazing management on dung beetle communities remains largely unknown. The purpose of this study was to investigate dung beetle abundance and diversity throughout the grazing season in the Nebraska Sandhills Ecoregion. Grazing treatments included: continuous grazing (CONT), low-stocking rotational grazing (LSR), high-stocking rotational grazing (HSR), and no grazing (NG). The abundance and diversity of dung beetles were measured in the 2014 and 2015 grazing seasons using dung-baited pitfall traps. Dung beetle abundance for each grazing treatment was characterized through four indices: peak …

Point-Of-Decision Prompts Increase Dietary Fiber Content Of Consumers’ Food Choices In An Online Grocery Shopping Simulation, Kristina Arslain, Christopher Gustafson, Devin J. Rose

Department of Food Science and Technology: Faculty Publications

Only 5% of Americans consume the recommended amount of dietary fiber. In an online simulated shopping experiment, we examined whether a fiber-focused point-of-decision prompt (PDP) would influence consumers to choose food products that were higher in this important nutrient. We hypothesized that participants exposed to the dietary fiber PDP would choose products with more dietary fiber/serving than those who were not exposed to the PDP. The experiment was completed by 753 participants. Participants were randomly assigned to a condition in which they were not exposed to a PDP (the no-PDP condition), a personalized PDP, or PDP without personalization. Choices in …

Introduction To Workforce Metrics, Quality Improvement Center For Workforce Development (Qic-Wd)

Other QIC-WD Products

It is important for Human Resources (HR) and child welfare leaders to start with a question-based mindset when analyzing workforce data (i.e., being thoughtful about what you and/or your stakeholders want to know), but it is also important to leave room to explore the data as well. This can only be accomplished if you know what is possible. This blog post describes some of what is possible to explore within the realm of workforce metrics as they relate to employee well-being, performance, and retention.

In many ways, the concept of workforce metrics is still in its infancy and many things …

Thriving, Megan Paul

Umbrella Summaries

What is thriving?

Thriving is defined as “a positive psychological state in which individuals experience both a sense of vitality and a sense of learning at work” (Spreitzer, Sutcliffe, Dutton, Sonenshein, & Grant, 2005, p. 538). Vitality refers to feeling energized, and learning is about experiencing personal growth and development (Spreitzer et al., 2005). The most popular measure of thriving includes ten items, with instructions to think about the questions in relation to work (Porath, Spreitzer, Gibson, & Garnett, 2012). Examples of vitality items include, “I have energy and spirit” and “I feel alive and vital,” and examples of learning …

Department of Animal Science: Faculty Publications

Since genetic engineering of pigs can benefit both biomedicine and agriculture, selecting a suitable gene promoter is critically important. The cytomegalovirus (CMV) promoter, which can robustly drive ubiquitous transgene expression, is commonly used at present, yet recent reports suggest tissue-specific activity in the pig. The objective of this study was to quantify ZsGreen1 protein (in lieu of CMV promoter activity) in tissues from pigs harboring a CMV-ZsGreen1 transgene with a single integration site. Tissue samples (n=35) were collected from neonatal hemizygous (n=3) and homozygous (n=3) piglets and ZsGreen1 abundance was determined via immunoblotting. ZsGreen1 was detected in all tissues, except …

Seasonal Forecast Based Preharvest Hedging, Eric D. Hunt, Cory Walters, Toni Klemm, Iyore Eronmwon

Cornhusker Economics

Given the immense effect of weather on agriculture, skillful weather forecasts are of importance to agricultural producers for effective decision making. Weather forecasts affect operational decisions such as whether or not to irrigate (where applicable), when to apply fertilizer, when to spray herbicide and pesticide, and certainly the timing of planting and harvesting. At the seasonal time scale, say in the spring, just before planting, weather forecasts may be used for strategic decision making on outcomes, say from preharvest hedging (hereafter referred to hedging), that will not be realized until the fall or harvest. Historically, the lack of skill in …

Assessing The Environmental Impacts Of Effluent From Aerobic Treatment Units, Sarah Deeb, Tamylles Souza Da Costa, Zahaan Eswani, Christopher Struchtemeyer

RURALS: Review of Undergraduate Research in Agricultural and Life Sciences

Aerobic treatment units (ATUs) serve as an alternative to traditional septic systems in many rural homes that lack access to municipal utilities. ATU effluent often flows directly into ditches that contain overgrown vegetation and rely on sunlight for disinfection. To date, it is unclear if effluent gets properly disinfected in these ditches, which is problematic since they often flow directly into major recreational water bodies. The goal of this work was to determine if ATUs negatively impact the environment by quantifying Escherichia coli and thermotolerant coliforms in: 1) ATU effluent, 2) Disposal ditches that received ATU effluent, and 3) Water …

National Drought Mitigation Center: Faculty Publications

Monitoring drought impacts in forest ecosystems is a complex process because forest ecosystems are composed of different species with heterogeneous structural compositions. Even though forest drought status is a key control on the carbon cycle, very few indices exist to monitor and predict forest drought stress. The Forest Drought Indicator (ForDRI) is a new monitoring tool developed by the National Drought Mitigation Center (NDMC) to identify forest drought stress. ForDRI integrates 12 types of data, including satellite, climate, evaporative demand, ground water, and soil moisture, into a single hybrid index to estimate tree stress. The model uses Principal Component Analysis …

Using Triallelic Snps For Determining Parentage In North American Yak (Bos Grunniens) And Estimating Cattle (B. Taurus) Introgression, Theodore S. Kalbfleisch, Jessica L. Petersen, R. G. Tait Jr., Jiansheng Qiu, Veronica Basnayake, Peter H. Hackett, Michael P. Heaton

Department of Animal Science: Faculty Publications

Background: Genetic testing for pedigree accuracy is critical for managing genetic diversity in North American (NA) yak (Bos grunniens ), a population expanded mostly from imported zoological park specimens. DNA testing also enhances species conservation by identifying recent B. taurus F1 hybrid ancestors (within three generations). Biallelic single nucleotide polymorphisms (SNPs) can accomplish either task, but increases the marker count and costs necessary to achieve both. Our aim was to identify novel, multifunctional, triallelic yak SNPs (tySNPs), with each having two alleles for yak parentage testing, and a third allele for identifying recent cattle introgression.

Methods: Genome sequences were …

Producer Services: An Engine For High-Wage Job Growth, Spencer Cook, Eric Thompson

Business in Nebraska

Producer services providers are firms that sell services primarily to the business community rather than to individuals and households. Many producer services businesses are classified in the professional, scientific, and technical service (PSTS) industry. Accounting firms, consultants, and computer design services are prominent examples of PSTS businesses that are worth studying for three reasons:

1. SUPPORT OF OTHER INDUSTRIES: PSTS industries supply the broader business community, making them a critical segment of the economy.

2. RAPID HIGH WAGE JOB GROWTH: Many PSTS industries are rapidly growing and pay high wages. The producer services sector, in fact, is the principal source …

Leveraging Abet Accreditation To Promote Inclusion Of Noise Control Engineering Concepts In Engineering Programs, Lily M. Wang, Bryan Beamer

Durham School of Architectural Engineering and Construction: Faculty Publications

Accreditation Board for Engineering and Technology, Inc. (ABET) accreditation is an internationally recognized system ensuring consistency and quality in engineering education programs. As a part of ABET accreditation, there is no set requirement for any general engineering program to include noise control engineering concepts in their curricula. However, one of the seven student outcomes that each ABET accredited engineering program must document is their students’ “ability to apply engineering design to produce solutions that meet specified needs with consideration of public health, safety, and welfare…” Controlling noise in the authors’ view is a fundamental strategy for protecting workers from occupational …

Investigating Microbial And Host Factors That Modulate Severity Of Clostridioides Difficile Associated Disease, Armando Lerma

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Clostridioides difficile is recognized as one of the most important pathogens in hospital and community healthcare settings. The clinical outcome of infection of toxigenic C. difficile infection (CDI) ranges from asymptomatic colonization to fulminant pseudomembranous colitis and death. In recent studies, it has been suggested that a high proportion of nosocomial CDI cases are transmitted from asymptomatic carriers which might be acting as infection reservoirs. Understanding what causes the different responses to infection could lead to the development of novel prevention and treatment strategies. Although several explanations have been proposed to explain variations in susceptibility, understanding of the exact mechanisms …

Hospital-Based Nurse Educators' Technology Readiness And Use Of High-Fidelity Simulation, Kristen Bryan Wessel

Department of Teaching, Learning, and Teacher Education: Theses and Other Student Research

This study used a cross-sectional survey design in an aim to compare the technology readiness (TR) of hospital-based nurse educators (HBNEs) that use highfidelity simulation (HFS) and those that do not use HFS in order to determine if a difference in TR might account for the lack of widespread adoption of HFS in the hospital setting. An online survey was administered to HBNEs from two national organizations: ANPD and SSH. Descriptive statistics and quantitative data analyses were conducted and reported as well as qualitative findings. Descriptive statistics revealed the average age of HBNE to be 45-46 years of age, possessing …

Career And Technical Education Teachers’ Beliefs About Developing Students’ Motivation To Write, Katie Graham

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Students in the U.S. write poorly. Although postsecondary and workplace writing expectations continue to rise, writing instruction has largely remained unchanged over time. As a result, student writing outcomes continue to fall below expectations from both an assessment and hirable proficiency standpoint. Career and Technical Education (CTE) provides a unique opportunity to motivate students who are otherwise disengaged in writing (ACTE, 2009). The benefits of helping students develop their writing-self efficacy has well-documented support (Bruning & Horn, 2009; Bandura, 1997; Pajares 2003; Pajares & Valiante, 2006). However, little is known about the writing opportunities provided in CTE classes or CTE …

Coyotes, Rick Tischaefer

Wildlife Damage Management Technical Series

The coyote (Canis latrans; Figure 1) is a medium-sized member of the canid family. Once primarily found in western deserts and grasslands, coyotes have expanded their range across North America and into diverse habitats, including urban areas. This expansion occurred during a time of extensive habitat change and efforts by people to suppress coyote populations to prevent damage. Coyotes can cause a variety of conflicts related to agriculture, natural resources, property, and human health and safety. This document highlights a variety of methods for reducing those conflicts. Coyotes are a highly adaptable species and may become habituated to some management …

Gambiense human African trypanosomiasis (g-HAT) is the chronic form of sleeping sickness caused by Trypanosoma brucei gambiense in West and Central Africa, while Trypanosoma brucei rhodesiense causes an acute form in eastern Africa. g-HAT is targeted for elimination as a public health problem by 2020 and 0 transmission by 2030 [1,2]. Control of g-HAT is largely based on identification and treatment of infected individuals, supplemented by control of the tsetse fly vectors [3]. There has been growing evidence that when both tsetse control and case identification activities are carried out simultaneously in the same geographies, elimination of the disease is …

Testing The Hypothesized Antipredator Defence Function Of Stridulation In The Spiny Orb-Weaving Spider, Micrathena Gracilis, Tyler B. Corey, Eileen A. Hebets

Eileen Hebets Publications

The observable diversity of antipredator defenses across organisms demonstrates predation’s impact on trait evolution. The functions of many traits that are presumed to have an antipredator function have never been directly tested. The spiny orb-weaving spider, Micrathena gracilis, for example, stridulates when grasped. While stridulation was first hypothesized to be an antipredator defense nearly 50 years ago, no data exist to support this hypothesis. To explore the form and function of M. gracilis stridulation, we first quantified the behavioral and acoustical properties of sound production. Next, using laboratory assays, we directly tested the effect of stridulation on survival with …

Assessing The Quantification Of Soy Protein In Incurred Matrices Using Targeted Lc-Ms/Ms, Jenna Krager

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Soy-derived ingredients are commonly added as auxiliary components to a diverse range of food products. The versatile end-applications of commercially processed soy ingredients is concerning for the safety of allergic consumers. Immunological detection of soy proteins in food matrices has some drawbacks, including loss of epitope binding and matrix masking. Therefore, the aim of this study was to assess naturally incurred matrices with an existing liquid-chromatography tandem mass spectrometry (LC-MS/MS) workflow to determine the recovery of total soy protein.

The existing LC-MS/MS workflow was time intensive. The peptide responses of five soy protein targets were compared between two dilution methods …

United States Department of Agriculture Wildlife Services: Staff Publications

Western North American forest ecosystems are experiencing rapid changes in disturbance regimes because of climate change and land use legacies (Littell et al. 2018). In many of these forests, the accumulation of surface and ladder fuels from a century of fire suppression, coupled with a warming and drying climate, has led to increases in the number of large fires (Westerling 2016) and the proportion of areas burning at higher severity (Safford and Stevens 2017, Singleton et al. 2018). While the annual area burned by fire is still below historical levels (Taylor et al. 2016), some forest types in the west …

One Out Of Ten: Low Sampling Efficiency Of Cloth Dragging Challenges Abundance Estimates Of Questing Ticks, Siiri Nyrhilä, Jani J. Sormunen, Satu Mäkelä, Ella Sippola, Eero J. Vesterinen, Tero Klemola

Harold W. Manter Laboratory of Parasitology: Library Materials

Hard ticks (Acari: Ixodidae) act as important vectors of zoonotic pathogens. For instance, Borrelia burgdorferi s.l. spirochetes pose a severe health risk as aetiological agents of Lyme borreliosis. Commonly, to study the abundance of questing (host-seeking) ticks, a 1 m2 piece of cloth is dragged over vegetation for a determined distance. Here, we designed a tick-sampling study to estimate the sampling efficiency of this standard method. We established 10 m dragging transects in a hemiboreal mixed forest patch in SW Finland for a 5-day monitoring period. Five of the transects were cloth-dragged 3× a day, whereas another five transects were …

Oddpub – A Text-Mining Algorithm To Detect Data Sharing In Biomedical Publications, Nico Riedel, Miriam Kip, Evgeny Bobrov

Copyright, Fair Use, Scholarly Communication, etc.

Open research data are increasingly recognized as a quality indicator and an important resource to increase transparency, robustness and collaboration in science. However, no standardized way of reporting Open Data in publications exists, making it difficult to find shared datasets and assess the prevalence of Open Data in an automated fashion.

We developed ODDPub (Open Data Detection in Publications), a text-mining algorithm that screens biomedical publications and detects cases of Open Data.

Assessment Centers, Tara Myers, Megan Paul

Umbrella Summaries

What are assessment centers?

Assessment centers measure knowledge, skills, abilities, and other characteristics by assessing participants’ responses to job-related simulations. Assessment centers can be used for hiring, placement, and career and skill development (Gaugler, Rosenthal, Thornton, and Bentson, 1987). Typically, participants complete a combination of in-basket, leaderless group discussion, role play, case analysis, and oral presentation exercises (Hoffman, Kennedy, LoPilato, Monahan, and Lance, 2015). Within each exercise, participants review job-relevant information and complete tasks. For the in-basket, participants are presented with documents (e.g., emails, memos, reports, requests—things that might be in an inbox) to which they provide responses and about …

Developing A Computer-Controlled Treat Dispenser For Canine Operant Conditioning, Walker Arce, Jeffrey R. Stevens

Center for Brain, Biology, and Behavior: Faculty Publications

When performing canine operant conditioning studies, the delivery of the reward can be a limiting factor of the study. While there are a few commercially available options for automatically delivering rewards, they generally require manual input, such as using a remote control, in accordance with the experiment script. This means that human reaction times and transmission distances can cause interruptions to the flow of the experiment. The potential for development of non-supervised conditioning studies is limited by this same factor. To remedy this, we retrofitted an off-the-shelf treat dispenser with new electronics that allow it to be remotely controllable as …
