Towards Modeling Human Attention From Eye Movements For Neural Source Code Summarization, Aakash Bansal, Bonita Sharif, Collin Mcmillan Jan 2023

Towards Modeling Human Attention From Eye Movements For Neural Source Code Summarization, Aakash Bansal, Bonita Sharif, Collin Mcmillan

School of Computing: Faculty Publications

Neural source code summarization is the task of generating natural language descriptions of source code behavior using neural networks. A fundamental component of most neural models is an attention mechanism. The attention mechanism learns to connect features in source code to specific words to use when generating natural language descriptions. Humans also pay attention to some features in code more than others. This human attention reflects experience and high-level cognition well beyond the capability of any current neural model. In this paper, we use data from published eye-tracking experiments to create a model of this human attention. The model predicts …

Turfgrass Alternatives For The Modern Yard, John Lonowski Jan 2023

Turfgrass Alternatives For The Modern Yard, John Lonowski

Department of Environmental Studies: Undergraduate Student Theses

The considerable maintenance and irrigation required of turfgrass lawns can often be seen as a fruitless endeavor, as it consumes substantial resources but yields minimal economic benefit. The goal of this paper is to highlight the resource needs of traditional turfgrass lawns and identify and test alternative lawn types that are still aesthetically pleasing while being more sustainable than traditional turfgrass. To obtain the results, the experiment was conducted in Alda, Nebraska employing a randomized complete block design, which tested four entries at two separate locations, each with three replications. The entries include: 1. Buffalograss, 2. Tall Fescue, 3. White …

Interspecific Oral Rabies Vaccine Bait Competition In The Southeast United States, Wesley C. Dixon, Jacob E. Hill, Richard Chipman, Amy J. Davis, Amy Gilbert, James C. Beasley, Olin E. Rhodes Jr., Guha Dharmarajan Jan 2023

Interspecific Oral Rabies Vaccine Bait Competition In The Southeast United States, Wesley C. Dixon, Jacob E. Hill, Richard Chipman, Amy J. Davis, Amy Gilbert, James C. Beasley, Olin E. Rhodes Jr., Guha Dharmarajan

United States Department of Agriculture Wildlife Services: Staff Publications

The United States Department of Agriculture’s National Rabies Management Program (NRMP) has coordinated the use of oral rabies vaccination (ORV) to control the spread of raccoon rabies virus variant west of the Appalachian Mountains since 1997. Working with state and local partners, the NRMP deploys ORV baits containing a rabies vaccine, primarily targeting raccoon populations (Procyon lotor). Bait competition between raccoons and non-target species may limit the effectiveness of ORV programs, but the extent of bait competition remains poorly quantified, particularly in the southeastern United States. We placed placebo ORV baits in bottomland hardwood (n = 637 baits) and upland …

Ovarian Inflammation Mediated By Toll-Like Receptor 4 Increased Transcripts Of Maternal Effect Genes And Decreased Embryo Development, Alison F. Ermisch, Katie L. Bidne, Scott G. Kurz, Kerri A. Bochantin, Jennifer R. Wood Jan 2023

Ovarian Inflammation Mediated By Toll-Like Receptor 4 Increased Transcripts Of Maternal Effect Genes And Decreased Embryo Development, Alison F. Ermisch, Katie L. Bidne, Scott G. Kurz, Kerri A. Bochantin, Jennifer R. Wood

Department of Animal Science: Faculty Publications

Obese women are subfertile and have reduced assisted reproduction success, which may be due to reduced oocyte competence. We hypothesize that consumption of a high-fat/high-sugar diet induces ovarian inflammation, which is a primary contributor to decreased oocyte quality and pre-implantation embryo development. To test this hypothesis, C57BL/6 (B6) mice with a normal inflammatory response and C3H/HeJ (C3H) mice with a dampened inflammatory response due to dysfunctional Toll-like receptor 4 were fed either normal chow or high-fat/high-sugar diet. In both B6 and C3H females, high-fat/high-sugar diet induced excessive adiposity and hyperglycemia compared to normal chow-fed counterparts. Conversely, ovarian CD68 levels and …

Evaluating Draft Environmental Protection Agency Emissions Models For Broiler Operations, G. Li, R. S. Gates, B. C. Ramirez, R. T. Burns Jan 2023

Evaluating Draft Environmental Protection Agency Emissions Models For Broiler Operations, G. Li, R. S. Gates, B. C. Ramirez, R. T. Burns

Department of Animal Science: Faculty Publications

In August 2021, the U.S. Environmental Protection Agency( EPA) released draft models to estimate daily NH3, H2S, PM2.5, PM10, and total suspended particulate semissions from U.S. broiler operations using inputs of daily mean ambient temperature, relative humidity, and live animal weight. The EPA developed these models using data sets collected between 2005 and 2007. It is important to note that over 15 yr have passed since the original data were collected, and broiler genetics, nutrition, and management have improved consideably. These models, if adopted, could have substantial impact on the U.S. broiler industry regarding air emission management and regulation. The …

Predator Feeding Rates May Often Be Unsaturated Under Typical Prey Densities, Kyle E. Coblentz, Mark Novak, John Delong Jan 2023

Predator Feeding Rates May Often Be Unsaturated Under Typical Prey Densities, Kyle E. Coblentz, Mark Novak, John Delong

School of Biological Sciences: Faculty Publications

Predator feeding rates (described by their functional response) must saturate at high prey densities. Although thousands of manipulative functional response experiments show feeding rate saturation at high densities under controlled conditions, it remains unclear how saturated feeding rates are at natural prey densities. The general degree of feeding rate saturation has important implications for the processes determining feeding rates and how they respond to changes in prey density. To address this, we linked two databases—one of functional response parameters and one on mass–abundance scaling—through prey mass to calculate a feeding rate saturation index. We find that: (1) feeding rates may …

Metamorphosis Imposes Variable Constraints On Genome Expansion Through Effects On Development, R. Lockridge Mueller,, Clayton E. Cressler, R S. Schwartz, R A. Chong, M. Butler Jan 2023

Metamorphosis Imposes Variable Constraints On Genome Expansion Through Effects On Development, R. Lockridge Mueller,, Clayton E. Cressler, R S. Schwartz, R A. Chong, M. Butler

School of Biological Sciences: Faculty Publications

Genome size varies ∼100,000-fold across eukaryotes and has long been hypothesized to be influenced by meta- morphosis in animals. Transposable element accumulation has been identified as a major driver of increase, but the nature of constraints limiting the size of genomes has remained unclear, even as traits such as cell size and rate of development co-vary strongly with genome size. Salamanders, which possess diverse metamorphic and non-metamorphic life histories, join the lung- fish in having the largest vertebrate genomes—3 to 40 times that of humans—as well as the largest range of variation in genome size. We tested 13 biologically-inspired hypotheses …

Farley, Joseph A. Cook, Sarah A. Sonsthagen, George K. Sage, Timothy H. Heaton, Sandra L. Talbot, Charlotte Lindqvist

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

During the Late Pleistocene, major parts of North America were periodically covered by ice sheets. However, there are still questions about whether ice-free refugia were present in the Alexander Archipelago along the Southeast (SE) Alaska coast during the last glacial maximum (LGM). Numerous subfossils have been recovered from caves in SE Alaska, including American black (Ursus americanus) and brown (U. arctos) bears, which today are found in the Alexander Archipelago but are genetically distinct from mainland bear populations. Hence, these bear species offer an ideal system to investigate long-term occupation, potential refugial survival and lineage turnover. Here, we present genetic …

Habitat Use By Sandhill Cranes Wintering In The Agricultural Landscape Of The Sacramento–San Joaquin River Delta Of California, Gary L. Ivey, Bruce D. Dugger, Caroline P. Herziger, Michael L. Casazza, Joseph P. Fleskes Jan 2023

Habitat Use By Sandhill Cranes Wintering In The Agricultural Landscape Of The Sacramento–San Joaquin River Delta Of California, Gary L. Ivey, Bruce D. Dugger, Caroline P. Herziger, Michael L. Casazza, Joseph P. Fleskes

Proceedings of the North American Crane Workshop

The Sacramento–San Joaquin Delta region of California is an important wintering region for sympatric greater (Grus canadensis tabida) and lesser (G. c. canadensis) sandhill cranes. Basic information about sandhill crane use of habitats in their winter landscape is needed to design a biologically driven conservation strategy. We monitored a sample of radio-tagged birds of each subspecies for 2 winters and conducted foraging counts to document their habitat use. Cranes used the major crops and habitat types that were available in the landscapes surrounding their roost sites and focused most of their foraging in grain crops. We examined habitat selection surrounding …

Whooping Crane Nesting Behavior, Parental Care, And Ecology At Wood Buffalo National Park, Andrew J. Caven, Michael J. Forsberg Jan 2023

Whooping Crane Nesting Behavior, Parental Care, And Ecology At Wood Buffalo National Park, Andrew J. Caven, Michael J. Forsberg

Proceedings of the North American Crane Workshop

We studied Whooping crane (Grus americana) nesting behavior and movement patterns at Wood Buffalo National Park using an instantaneous scan sampling approach. We also photo-documented important behavioral and ecological observations. Data were collected from 2 to 9 June 2023 from before 3:00 to after 22:00 hours. We completed 88 hours of observation and documented nest swapping about every 3.2 hours. The female incubated/brooded 3.3-10.9% more than the male, and the probability of incubation/brooding declined by 49% after the second chick began pipping and by 99% after both chicks had hatched. The eldest chick was successfully provisioned 16 hours and 33 …

Inland Habitat Selection Model For Wintering Whooping Cranes, Karen Tyrell, Kristin Brightwell, Matthew Crane, Wade Harrell, Rosa Palmer, Aaron T. Pearse, Ted Owen Jan 2023

Inland Habitat Selection Model For Wintering Whooping Cranes, Karen Tyrell, Kristin Brightwell, Matthew Crane, Wade Harrell, Rosa Palmer, Aaron T. Pearse, Ted Owen

Proceedings of the North American Crane Workshop

Inland habitat use by wintering Aransas-Wood Buffalo whooping cranes (Grus americana) is expected to increase given projected population growth and observations of some whooping cranes using inland winter habitat in addition to coastal marshes. We developed resource utilization functions using ‘random forests’ to model whooping crane use as a function of environmental covariates considered important for whooping crane use. Covariates associated with distance to cropland, distance to development, and wetness or standing water were the most influential in model prediction. The model estimated that the 50% predicted use contour encompassed 34,925 hectares (ha) and the 95% predicted use contour encompassed …

Mortality Of Fledged Whooping Cranes In The Aransas-Wood Buffalo Population, Kristin Brightwell, Matt Rabbe, Aaron T. Pearse, Ben Bainbridge, Karen Tyrell, Clayton Derby Jan 2023

Mortality Of Fledged Whooping Cranes In The Aransas-Wood Buffalo Population, Kristin Brightwell, Matt Rabbe, Aaron T. Pearse, Ben Bainbridge, Karen Tyrell, Clayton Derby

Proceedings of the North American Crane Workshop

Maintaining accurate mortality records for endangered species is important for guiding management and conservation actions. Mortalities of whooping cranes (Grus americana) in the Aransas-Wood Buffalo Population (AWBP) are documented in published records from 1950 through 2010. This paper documents publicly available records of known mortalities from 2011 through 2023, and updates historic records from 1950 to 2010. Public sightings and telemetry carcass records were restricted to fledged whooping cranes from the AWBP and stratified by confirmed, suspected, and unknown causes across the annual range (i.e., summer, migration, and winter). This mortality update provides more certainty associated with available carcass data …

Differential Habitat Use Of Wintering Whooping Cranes Throughout The Range Of The Eastern Migratory Population, Hillary L. Thompson, Anne E. Lacy, Robert F. Baldwin, Patrick G. R. Jodice Jan 2023

Differential Habitat Use Of Wintering Whooping Cranes Throughout The Range Of The Eastern Migratory Population, Hillary L. Thompson, Anne E. Lacy, Robert F. Baldwin, Patrick G. R. Jodice

Proceedings of the North American Crane Workshop

In 2001, a reintroduced population of whooping cranes (Grus americana), the Eastern Migratory Population (EMP), was established in the eastern United States. There has been no assessment of habitat use of the EMP across the current winter distribution. During 2 winters, we used radio-telemetry to track groups of cranes each for 1 day. We grouped sites into 3 regions, based on natural clustering: north (Illinois, Indiana, Kentucky), central (Tennessee, Alabama), and south (Georgia, Florida, Louisiana). Home ranges decreased in size from north to south (4.9 ± 2.8, 3.1 ± 1.0, and 2.3 ± 0.5 km2, respectively). In the north and …

Comparisons Of Migration Patterns Between Parent-Reared And Costume-Reared Whooping Cranes In The Eastern Migratory Population, 2012–2023, Mary Anderson, Glenn H. Olsen, Susie Dunham, Hillary L. Thompson, Marianne M. Wellington Jan 2023

Comparisons Of Migration Patterns Between Parent-Reared And Costume-Reared Whooping Cranes In The Eastern Migratory Population, 2012–2023, Mary Anderson, Glenn H. Olsen, Susie Dunham, Hillary L. Thompson, Marianne M. Wellington

Proceedings of the North American Crane Workshop

Whooping cranes (Grus americana) have been raised and released into the Eastern Migratory Population (EMP) since 2001. Cranes either were costume-reared and learned their migration route by following an ultralight aircraft, were costume-reared and released in fall near adult cranes (known as direct autumn release), or were parent-reared by captive adult whooping crane pairs and released in the fall near adult whooping cranes. Compared to costume-rearing, parent-rearing encourages conspecific learning prior to release, but needs further research to understand how it may influence post-release behaviors including migration. This study compared the migratory timing and length of parent-reared whooping cranes and …

Temporal Patterns Of Sandhill Crane Use Of The Pecos River Valley, Chaves County, New Mexico, James B. Montgomery Jr. Jan 2023

Temporal Patterns Of Sandhill Crane Use Of The Pecos River Valley, Chaves County, New Mexico, James B. Montgomery Jr.

Proceedings of the North American Crane Workshop

The Pecos River Valley is an important stopover area for both migrating and wintering sandhill cranes (Grus canadensis) in southeastern New Mexico. The combination of shallow impoundments and a playa lake at Bitter Lake National Wildlife Refuge, off-refuge shallow ponds and riverine wetlands, and approximately 20,000 ha of nearby irrigated farmlands in Chaves County provided roosting and foraging areas used by the cranes. Once per week sandhill cranes were counted when departing their roosts during September through April 2005–2024. The fall migration during October and November peaked at 24,431 ± 204 (SE). During this peak period, cranes divided foraging between …

Movement Of Eastern Migratory Whooping Cranes Outside The Nonessential Experimental Population Range, 2002–2024, Nicole M. Gordon, Eleanor A. Laack, Hannah R. Macinnes, Alicia M. Ward, Hillary L. Thompson

Proceedings of the North American Crane Workshop

Whooping cranes (Grus americana) are listed as an endangered species under the Endangered Species Act (ESA), with 1 historic migratory population and multiple reintroduced populations. The reintroduced populations, including the Eastern Migratory Population (EMP), are considered nonessential experimental populations (NEP) under section 10j of the ESA. Within the boundaries of the NEP range, whooping cranes are treated with the protection of a threatened species on federal lands but are treated as a species under consideration for listing on private lands. However, if an individual exits the NEP range, they are treated as federally endangered and have the full protections of …

Telling Your Story: Stewardship And The Honors College, Andrew Martino Jan 2023

Telling Your Story: Stewardship And The Honors College, Andrew Martino

National Collegiate Honors Council Monographs: Chapters

Honors administrators, particularly honors college deans, find themselves in positions not necessarily equivalent to academic deans in other disciplines. Often, honors college deans function more like provosts in that they need to attend to multiple disciplines simultaneously, while also often carrying obligations in teaching and advising. In addition, the initiation, cultivation, and stewardship of donors to the college are essential components to the honors college dean’s portfolio. This task may be particularly challenging for a dean in honors in that many potential donors are intellectually and emotionally tied to their specific major and/or school or college. And yet, fundraising, especially …

Effects Of Lead Exposure On Birds Breeding In The Southeast Missouri Lead Mining District, Rebecka Brasso, Danielle Cleveland, Frank R. Thompson Iii, David E. Mosby, Kathy Hixson, Melissa Roach, Barnett A. Rattner, Natalie K. Karouna-Renier, Julia S. Lankton Jan 2023

Effects Of Lead Exposure On Birds Breeding In The Southeast Missouri Lead Mining District, Rebecka Brasso, Danielle Cleveland, Frank R. Thompson Iii, David E. Mosby, Kathy Hixson, Melissa Roach, Barnett A. Rattner, Natalie K. Karouna-Renier, Julia S. Lankton

United States Geological Survey: Staff Publications

Lead mining in the Southeast Missouri Lead Mining District began in the 1700s and continued for nearly 300 years; the waste piles associated with smelting, mining, and milling of lead ores have released metal residues that have contaminated soil and water in the region. Previous studies in the district have indicated potential harm to wildlife, including birds, because of elevated lead concentrations associated with mining. Exposure to soil-borne lead was correlated with elevated lead concentrations in tissues, inhibition of δ-aminolevulinic acid dehydratase (δALAD), and renal lesions in birds foraging on ground-dwelling invertebrates at contaminated sites (compared to reference sites) in …

Migrants, Covid-19, And Italy: A Multimodal Critical Discourse Analysis Of The Construction Of And Resistance To Nationalist Discourses, Alessia Barbici Wagner, Theresa Catalano, Bryan Meadows

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Migration has historically been a controversial issue around the world and one that has often been harnessed by people in power (or people hoping to gain power) for their own political agendas. In times of a global pandemic, the scapegoating of migrants has only increased, often rooted in nationalist ideologies which lead to policies and practices that harm migrants and the larger society. The present paper employs multimodal critical discourse analysis to explore how nationalist ideologies supported by right-wing populism are constructed visually and verbally during COVID-19 on Italian social media in regard to migration. We analyze Giorgia Meloni’s (leader …
