Weed Control Efficacy Of Bio-Based Sprayable Mulch Films In Specialty Crop Systems, Eliott Gloeb

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

A sprayable bio-based mulch film (biofilm) could present a more sustainable weed management tool for specialty crop producers than conventional plastic mulch films while also offering flexibility in application patterns and timing. From 2017 to 2019, six greenhouse trials and four field trials were conducted at the University of Nebraska-Lincoln to study the effects of biofilm application on weed suppression and crop yields. Multiple application rates (0.81 L/m² - 9.78 L/m²) and application times (prior to weed emergence and post weed emergence) were tested. Corn starch, glycerol, keratin hydrolysate, corn gluten meal, corn zein, and isolated soy …

Fighting For 504: Negotiating Hegemonic Ability Through Verbal Advocacy And Disabled Embodiment, Drew Finney

Department of Communication Studies: Dissertations, Theses, and Student Research

In my thesis, I look at San Francisco’s 504 sit-in for disability rights. I argue that both the verbal advocacy and the embodied actions of protestors demonstrate that dis/ability is constructed through a hegemonic process. I contend that combating hegemonic understandings of disability creates a tension between being a counter hegemonic movement and desiring the benefits of hegemonic legibility. To make these arguments, my thesis draws several conclusions. I argue that activists enacted a civil- rights framework to communicate the need for Section 504 to the public. I explain that activists adopted the role of educator to address problematic ideas …

Irrigation, Carbon Amelioration, Nitrogen, And Stover Removal Effects On Continuous Corn, Marty Schmer, Virginia L. Jin, Richard B. Ferguson, Brian J. Wienhold

Department of Agronomy and Horticulture: Faculty Publications

Corn (Zea mays L.) residue or stover is harvested as supplemental feed for livestock and is a potential feedstock for cellulosic biofuels. Limited information is available on corn stover removal effects on grain yield under different irrigation rates, nitrogen (N) fertilizer rates, and practices to maintain soil carbon (C) and minimize soil erosion. We evaluated potential interactions between irrigation rate (full or limited), C amelioration practices (cover crop, surface-applied manure, or no amelioration practice), fertilizer N management (125 or 200 kg N ha⁻¹), and stover removal (residue removal or no residue removal), on no-till continuous corn …

Coronavirus Food Assistance Program For Livestock Producers, Bradley Lubben

Extension Farm and Ranch Management News

United States Congress and the President have approved multiple phases of COVID-19 assistance to date including the $2.3 trillion CARES (Coronavirus Aid, Relief, and Economic Security) Act passed in March that provides financial support for agricultural producers as a small part of the overall relief.

While agricultural producers and agribusinesses are eligible for two programs administered through the Small Business Administration, including the Paycheck Protection Program (PPP) and Economic Injury Disaster Loans (EIDLs), the primary support for agriculture is coming from USDA through the Coronavirus Food Assistance Program (CFAP). The CARES Act provided $9.5 billion directly to the Secretary of …

Psychological Safety, Rebecca Orsi, Megan Paul

Umbrella Summaries

What is psychological safety?

Psychological safety is the belief that one’s workplace is safe for interpersonal risk taking (Edmondson, 1999; Kahn, 1990). It has been suggested that psychological safety is a condition necessary for people to feel attached to and engaged in their work, when people feel they can reveal themselves without fear of negative consequences to status or career (Kahn, 1990). Psychological safety is not only an individual perception; it can also be a group-level shared belief that a team or work group is safe for interpersonal risk taking (Edmondson, 1999). The most popular way to measure psychological safety …

Working Post-Pandemic: What Campus Employees Need (Now), Marcia Dority Baker, Teri Abbo

Information Technology Services: Publications

Now is the time for institutional leaders to ask employees what they need to successfully transition back to working on campus. It is also a good time for employees to ask their managers what remote work options will be available in the long term.

In late April, EDUCAUSE conducted a QuickPoll survey asking the higher education technology workforce how they are doing. The results of the poll provide great (and timely) insight on how the coronavirus pandemic has impacted the work, location, and workload of technology employees.

Information Technology Services: Publications

In late April, EDUCAUSE conducted a QuickPoll survey asking the higher education technology workforce how they are doing.1 The results of the poll provide great (and timely) insight on how the coronavirus pandemic has impacted the work, location, and workload of technology employees. The results also show how the pandemic has impacted these employees as individuals. The looming questions that remain are, "What now?" and "How can institutions embrace new opportunities that may arise?" Institutions need to actively reach out to employees and ask, "What do you need?"

“Because Like – And So I Don’T – So I Think It’S Maybe, I Don’T Know”: Performing Traumatic Effects While Reading Lynda Barry’S The Freddie Stories, David Lewkowich, Michelle Miller Stafford

SANE journal: Sequential Art Narrative in Education

As a picture of childhood composed from the point of view of a young boy named Freddie, who suffers the effects of repeated and ongoing trauma, the experience of reading The Freddie Stories presents a number of interpretive challenges: its main character is often split and in various states of disassociation, the difference between dreaming and waking life is not always obvious, multiple monsters appear in different and changeable forms, and as Freddie experiences repeated difficulties with language and cognitive function, his traumatic past enfolds upon the time in which the story is set. In this paper, we analyze how …

The Trait Repertoire Enabling Cyanobacteria To Bloom Assessed Through Comparative Genomic Complexity And Metatranscriptomics, Huansheng Cao, Yohei Shimura, Morgan M. Steffen, Zhou Yang, Jingrang Lu, Allen Joel, Landon Jenkins, Masanobu Kawachi, Yanbin Yin, Ferran Garcia-Pichel

Food for Health: Publications

Water bloom development due to eutrophication constitutes a case of niche specialization among planktonic cyanobacteria, but the genomic repertoire allowing bloom formation in only some species has not been fully characterized. We posited that the habitat relevance of a trait begets its underlying genomic complexity, so that traits within the repertoire would be differentially more complex in species successfully thriving in that habitat than in close species that cannot. To test this for the case of bloom-forming cyanobacteria, we curated 17 potentially relevant query metabolic pathways and five core pathways selected according to existing ecophysiological literature. The available 113 genomes …

Genetic Biocontrol For Invasive Species, John L. Teem, Luke Alphey, Sarah Descamps, Matt P. Edgington, Owain Edwards, Neil Gemmell, Tim Harvey-Samuel, Rachel L. Melnick, Kevin P. Oh, Antoinette J. Piaggio, J. Royden Saah, Dan Schill, Paul Thomas, Trevor Smith, Andrew Roberts

United States Department of Agriculture Wildlife Services: Staff Publications

Invasive species are increasingly affecting agriculture, food, fisheries, and forestry resources throughout the world. As a result of global trade, invasive species are often introduced into new environments where they become established and cause harm to human health, agriculture, and the environment. Prevention of new introductions is a high priority for addressing the harm caused by invasive species, but unfortunately efforts to prevent new introductions do not address the economic harm that is presently manifested where invasive species have already become established. Genetic biocontrol can be defined as the release of organisms with genetic methods designed to disrupt the reproduction …

Air Temperature, Carbon Dioxide, And Ammonia Assessment Inside A Commercial Cage Layer Barn With Manure-Drying Tunnels, W Zheng, Y Xiong, R S. Gates, K W. Koelkebeck

Department of Animal Science: Faculty Publications

Understanding the air temperature distribution, ammonia (NH₃) and carbon dioxide (CO₂) levels in poultry housing systems are crucial to poultry health, welfare, and productivity. In this study, 4 Intelligent Portable Monitoring Units and 7 temperature sensors were installed inside and between the cages and above 2 minimum ventilation fans of a commercial stacked-deck cage laying hen house in the Midwest United States (425,000 laying hens) to continuously monitor the interior environment over a 6-month period. During cold conditions (March 12th–May 22nd), there was a variation noted, with barn center temperatures consistently being highest in the longitudinal …

Conquering A Legislative Court: Murphy And An Opportunity For Clarity In Indian Country, Michael R. Faz

Nebraska Law Bulletin (Selected Issues)

In 2017, the Tenth Circuit declared that the Muscogee (Creek) Nation continues to govern a large swarth of land in Eastern Oklahoma because Congress never stripped the Creek of jurisdiction. The issue before the court was whether the twentieth century policy of allotment removed tribal jurisdiction from the land in dispute. Following Supreme Court precedent established by Solem v. Bartlett, the court ruled that the Creek Nation persists. By implication, many legal scholars argue that since Congress’s treatment of the Creek resembled all Five Civilized Tribes, the State of Oklahoma lacks jurisdiction in nearly half of its current territory, including …

‘Do Unto Others’: Religiosity And Bullying In Adolescence And Emerging Adulthood, Joseph Jochman

Department of Sociology: Dissertations, Theses, and Student Research

This dissertation examines associations between religiosity and bullying in adolescence and emerging adulthood across three empirical chapters. The first empirical chapter uses data from the National Study of Youth and Religion Wave 1 (N=3,137) to assess the likelihood of bullying and religious victimization by key religious factors in youth. Results show that religious affiliation, religious practices, and religious views and beliefs are all associated with differential likelihoods of bullying. Mainline Protestants and youth with higher religious salience and scripture reading had lower likelihoods of bullying perpetration. Higher service attendance and religious youth group participation, however, were associated with increased likelihood …

Perceived Organizational Support, Megan Paul

Umbrella Summaries

What is perceived organizational support?

Perceived organizational support (POS) refers to employee perceptions regarding the extent to which their employer “values their contributions and cares about their well-being” (Eisenberger, Huntington, Hutchison, & Sowa, 1986, p. 501). In the social exchange between employees and employers, it is the organizational equivalent of employees’ commitment to the organization, though it is based on employees’ perceptions, rather than the organization’s perspective. In short, it represents “employees' inferences concerning the organization's commitment to them” (Eisenberger et al., 1986, p. 500). Beliefs about the organization’s commitment are thought to stem from employees’ interactions with other members …

Usda Meatpacking Inspectors Receive Hand Sanitizer Made At Nebraska U, Leslie Reed

Nebraska Innovation Campus Materials

Food safety inspectors employed by the USDA’s Food Safety and Inspection Service are receiving a supply of hand sanitizer thanks to an innovative partnership between Nebraska’s ethanol industry and the University of Nebraska–Lincoln. The hand sanitizer will be used by the men and women responsible for inspecting more than 6,500 meat-processing facilities across the country, ranging from “mom-and-pop” facilities that handle only a few animals at a time to the giant beef, poultry and pork plants that employ thousands of people. “Food Safety and Inspection Service inspectors provide critical support to our food supply chain and also to the livestock …

Advanced Health Care Directives In Nebraska: Health Care Power Of Attorney And Living Wills, J. David Aiken

Extension Farm and Ranch Management News

First paragraph:

During this period of coronavirus pandemic, some Nebraskans may be concerned about how medical decisions will be made for them if they are unable to communicate their wishes to their health care providers themselves. In these circumstances, health care providers will normally consult with the patient’s family members who may be available (spouse, then adult children–consensus, then parents, etc.) If no family members are present, the health care providers will use their best medical judgment in making health care decisions for the patient.

Photographic Validation Of Target Versus Nontarget Take Of Brown Treesnake Baits, Shane R. Siers, Aaron B. Shiels, Cynthia G. Payne, Francinem M. Chlarson, Craig S. Clark, Stephen M. Mosher

United States Department of Agriculture Wildlife Services: Staff Publications

Use of toxic baits or other tools for managing nuisance species must ensure that the species of interest is adequately targeted while exposure to nontarget species is minimized. Nontarget takes of acetaminophen‐laced baits for control of invasive brown treesnakes (Boiga irregularis) on Guam may put those animals at risk of lethal intoxication and render the bait unavailable to the intended target species. We used wildlife cameras to identify species removing toxic and nontoxic baits from brown treesnake bait stations designed to exclude nontarget taxa in 2015 and 2016. Throughout various sites and habitat types, and balanced by season (wet vs. …

Time Allocation To Resources By Three Species Of Rats (Rattus Spp.) In A Radial Arm Maze, Gary Witmer, Nathan P. Snow, Rachael S. Moulton

United States Department of Agriculture Wildlife Services: Staff Publications

Context. Introduced rats (Rattus spp.) can pose a serious threat to native flora and fauna, especially on islands where most species have evolved in the absence of terrestrial predators. Effective detection and eradication methods for introduced rats are essential to the maintenance of insular ecosystem integrity. Thus, it is important to better understand the behaviour of rats when they first arrive in a new setting.

Aims. To determine whether rats would find some novel stimuli to be significantly more attractive than other novel stimuli.

Methods. An eight-arm radial maze was used to study the behaviour of three species of Rattus …

Interactions With Humans Shape Coyote Responses To Hazing, Julie K. Young, Edd Hammill, Stewart W. Breck

United States Department of Agriculture Wildlife Services: Staff Publications

Medium and large carnivores coexist with people in urban areas globally, occasionally resulting in

negative interactions that prompt questions about how to reduce human-wildlife conflict. Hazing,

i.e., scaring wildlife, is frequently promoted as an important non-lethal means for urbanites to reduce

conflict but there is limited scientific evidence for its efficacy. We used a population of captive coyotes (Canis latrans) to simulate urban human-coyote interactions and subsequent effects of hazing on coyote behavior. Past experiences with humans significantly affected the number of times a coyoteapproached a human to necessitate hazing. coyotes that had been hand fed by adults had to …

United States Department of Agriculture Wildlife Services: Staff Publications

Invasive species are a leading driver of global change, with consequences for biodiversity and society. Because of extraordinary rates of endemism, introduction, and extinction, Hawaii offers a rich platform for exploring the cross-disciplinary challenges of managing invasive species in a dynamic world. We highlight key successes and shortcomings to share lessons learned and inspire innovation and action in and beyond the archipelago. We then discuss thematic challenges and opportunities of broad relevance to invaded ecosystems and human communities. Important research needs and possible actions include eradicating mammals from mainland island sanctuaries, assessing hidden threats from poorly known introduced species, harnessing …

Deciphering Interactions Between White-Tailed Deer And Approaching Vehicle, Morgan Pfeiffer, Raymond B. Iglay, Thomas W. Seamans, Bradley F. Blackwell, Travis L. Devault

United States Department of Agriculture Wildlife Services: Staff Publications

Deer-vehicle collisions are a major transportation hazard, but factors affecting deer escape decision-making in response to vehicle approach remain poorly characterized. We made opportunistic observations of deer response to vehicle approach during daylight hours on a restricted- access facility in Ohio, USA (vehicle speeds were ≤64 km/h). We hypothesized that animal proximity to the road, group size, vehicle approach, and ambient conditions would affect perceived risk by white-tailed deer (Odocoileus virginianus) to vehicle approach, as measured by flight-initiation distance (FID). We constructed a priori models for FID, as well as road-crossing behavior. Deer responses were variable and did not demonstrate …

Perceptions Of Organizational Politics, Penny Putnam Collins, Megan Paul

Umbrella Summaries

What are perceptions of organizational politics?

Perceptions of organizational politics (POP) is defined as an individual’s subjective assessment of the degree to which their work setting is believed to be self-serving of some individuals and groups, to the detriment of others (Ferris, Harrell-Cook, & Dulebohn, 2000). A popular and recommended 15-item measure assesses POP through three factors: general political behavior, going along to get ahead, and pay and promotion (Kacmar & Carlson, 1997). Example items from each factor include, “People in this organization attempt to build themselves up by tearing others down,” “Sometimes it is easier to remain quiet than …

Evaluating Moose Alces Alces Population Response To Infestation Level Of Winter Ticks Dermacentor Albipictus, Daniel D. Ellingwood, Peter J. Pekins, Henry Jones, Anthony R. Musante

United States Department of Agriculture Wildlife Services: Staff Publications

Many wildlife populations are experiencing a variety of environmental pressures due to the direct and indirect consequences of a changing climate. In the northeast, USA, moose Alces alces are declining in large part because of the increasing parasitism by winter tick Dermacentor albipictus, facilitated by high host density and optimal environmental conditions. To test this hypothesis, and better understand the influence of this interaction on the stability of the regional population, we constructed a population viability model using data collected through comprehensive survival and productivity studies in 2002–2005 and 2014–2018 in northern New Hampshire. Years of heavy tick infestation (epizootics) …

Spillover Of Sars-Cov-2 Into Novel Wild Hosts In North America: A Conceptual Model For Perpetuation Of The Pathogen, Alan B. Franklin, Sarah N. Bevins

United States Department of Agriculture Wildlife Services: Staff Publications

There is evidence that the current outbreak of the novel coronavirus SARS-CoV-2, which causes COVID-19, is of animal origin. As with a number of zoonotic pathogens, there is a risk of spillover into novel hosts. Here, we propose a hypothesized conceptual model that illustrates the mechanism whereby the SARS-CoV-2 could spillover from infected humans to naive wildlife hosts in North America. This proposed model is premised on transmission of SARS-CoV-2 from human feces through municipal wastewater treatment plants into the natural aquatic environment where potential wildlife hosts become infected. We use the existing literature on human coronaviruses, including SARS CoV, …

Stochastic Simulation Of Cellular Metabolism, Emalie J. Clement, Thomas T. Schulze, Ghada A. Soliman, Beata Joanna Wysocki, Paul H. Davis, Tadeusz A. Wysocki

Department of Electrical and Computer Engineering: Faculty Publications

Increased technological methods have enabled the investigation of biology at nanoscale levels. Such systems require the use of computational methods to comprehend the complex interactions that occur. The dynamics of metabolic systems have been traditionally described utilizing differential equations without fully capturing the heterogeneity of biological systems. Stochastic modeling approaches have recently emerged with the capacity to incorporate the statistical properties of such systems. However, the processing of stochastic algorithms is a computationally intensive task with intrinsic limitations. Alternatively, the queueing theory approach, historically used in the evaluation of telecommunication networks, can significantly reduce the computational power required to generate …

The Impact Of The Covid-19 Pandemic On Marginalized Populations In The United States: A Research Agenda, Neeta Kantamneni

Department of Educational Psychology: Faculty Publications

International and national crises often highlight inequalities in the labor market that disproportionately affect individuals from marginalized backgrounds. The COVID-19 pandemic, and the resulting changes in society due to social distancing measures, has showcased inequities in access to decent work and experiences of discrimination resulting in many of the vulnerable populations in the United States experiencing a much harsher impact on economic and work-related factors. The purpose of this essay is to describe how the COVID-19 pandemic may differentially affect workers of color, individuals from low-income backgrounds, and women in complex ways. First, this essay will discuss disproportionate representation of …

Medically Defined Infertility Versus Self-Perceived Fertility Problem: Implications Of Survey Wording For Assessing Associations With Depressive Symptoms, Michele H. Lowry, A L. Greil, J Mcquillan, A Burch, K M. Shreffler

Department of Sociology: Faculty Publications

Objective: To examine how measures of infertility based on medical criteria and based on self-perception relate to depressive symptoms among women with infertility. Background: Survey-based studies of depressive symptoms have used either measures of self-reported infertility based on meeting medical criteria or measures of self-perceived fertility problems, but seldom both. It is, therefore, not known which type of measure is more closely associated with depressive symptoms. Materials and Methods: Using ordinary least-squares multiple regression, this study compares associations between a measure of meeting medical criteria for infertility and a measure of self-perceived fertility problems with a common measure of depressive …

Public Perspectives And Media Reporting Of Wolf Reintroduction In Colorado, Rebecca Niemiec, Richard E.W. Berl, Mireille Gonzalez, Tara Teel, Cassiopeia Camara, Matthew Collins, Jonathan Salerno, Kevin Crooks, Courtney Schultz, Stewart Breck, Dana Hoag

United States Department of Agriculture Wildlife Services: Staff Publications

In the state of Colorado, a citizen ballot initiative to reintroduce gray wolves (Canis lupus) is eliciting polarization and conflict among multiple stakeholder and interest groups. Given this complex social landscape, we examined the social context surrounding wolf reintroduction in Colorado as of 2019. We used an online survey of 734 Coloradans representative in terms of age and gender, and we sampled from different regions across the state, to examine public beliefs and attitudes related to wolf reintroduction and various wolf management options. We also conducted a content analysis of media coverage on potential wolf reintroduction in 10 major daily …
