With Liberty And Justice For The Wealthy: The Criminalization Of The American Poor, Ashlyn Dickmeyer

Honors Program: Senior Projects (Public)

The last phrase of the Pledge of Allegiance states “with liberty and justice for all”. However, not everyone has access to this liberty and justice. Liberty and justice can be bought in this country for a price, and those who can’t afford to pay it are often left in the hands of those who can. One of the most prominent ways to see this is by analyzing the criminal justice system. Despite clauses in the Fourteenth Amendment and court cases like Gideon v. Wainwright (1963) establishing and upholding that the poor are entitled to equal treatment within the criminal justice …

Searches For Additional Higgs Bosons And For Vector Leptoquarks In Τ Τ Final States In Proton-Proton Collisions At √S = 13 Tev, A. Tumasyan

Kenneth Bloom Publications

Three searches are presented for signatures of physics beyond the standard model (SM) in τ τ final states in proton-proton collisions at the LHC, using a data sample collected with the CMS detector at √s = 13TeV, corresponding to an integrated luminosity of 138 fb⁻¹. Upper limits at 95% confidence level (CL) are set on the products of the branching fraction for the decay into τ leptons and the cross sections for the production of a new boson ø, in addition to the H(125) boson, via gluon fusion (ggø) or in association with b quarks, …

Blind Luck: A Narrative Exploration Of French Sayings And Superstitions, Isabella North

Honors Program: Senior Projects (Public)

The goal of this Honors Thesis was to explore French superstitions and idioms through a fictional story. To facilitate the inclusion of a range of sayings and superstitious beliefs, the short story “Jamais Deux Sans Trois” is a borderline paranormal piece of fiction which is meant to call into question how the reader interprets the world. The story, written in French, revolves around a pair of best friends and their experiences with a series of events which may or may not be explained through the lens of superstitions, depending on which character is asked at which point in the story. …

Do Ceo Gratification Preferences Influence Accounting Choices Near Retirement?, Nicholas Wilson

College of Business: Dissertations, Theses, and Student Research

CEOs near retirement are less motivated to act in shareholders' best interests than those planning to remain indefinitely; this is the horizon problem. Financial reporting that personifies the horizon problem includes an abrupt reduction in discretionary spending and an increase in current accounting earnings; this abrupt change in reporting is potentially detrimental to long-term gains. Gratification preference, defined by observable tendencies, is a personal characteristic reflecting one's prior life experiences and environments. This study offers an archival measure of these gratification preferences and examines whether these preferences mitigate or exacerbate the CEO horizon problem. The results suggest that discretionary accounting …

Myzus Fataunae Shinji (Hemiptera: Aphididae), Pilea Aphid, New To North America, Susan E. Halbert, Jade S. Allen, Matthew R. Moore, Katherine E.O. Fairbanks, Masakazu Sano, Gary L. Miller

Insecta Mundi

Minute aphids belonging to the species Myzus fataunae Shinji (Hemiptera: Aphididae) were found at a nursery in Seminole County, Florida. Morphological and molecular data support this determination. The Florida population only colonized species of Pilea Lindl. in our host range experiments. It did not colonize Fatoua villosa. Nakai. Likewise, it did not colonize tested common Florida species of Urticaceae other than Pilea spp. Myzus fataunae is adventive, and it appears to be established in the United States.

Daugherty Water for Food Global Institute: Faculty Publications

Long-term atmospheric CO₂ concentration records have suggested a reduction in the positive effect of warming on high-latitude carbon uptake since the 1990s. A variety of mechanisms have been proposed to explain the reduced net carbon sink of northern ecosystems with increased air temperature, including water stress on vegetation and increased respiration over recent decades. However, the lack of consistent long-term carbon flux and in situ soil moisture data has severely limited our ability to identify the mechanisms responsible for the recent reduced carbon sink strength. In this study, we used a record of nearly 100 site-years of eddy covariance …

Estimating The Prevalence Of Two Or More Diseases Using Outcomes From Multiplex Group Testing, Md S. Warasi, Joshua M. Tebbs, Christopher S. Mcmahan, Christopher R. Bilder

Department of Statistics: Faculty Publications

When screening a population for infectious diseases, pooling individual specimens (e.g., blood, swabs, urine, etc.) can provide enormous cost savings when compared to testing specimens individually. In the biostatistics literature, testing pools of specimens is commonly known as group testing or pooled testing. Although estimating a population-level prevalence with group testing data has received a large amount of attention, most of this work has focused on applications involving a single disease, such as human immunodeficiency virus. Modern methods of screening now involve testing pools and individuals for multiple diseases simultaneously through the use of multiplex assays. Hou et al. (2017, …

Penguins Go Parallel: A Grammar Of Graphics Framework For Generalized Parallel Coordinate Plots, Susan Vanderplas, Yawei Ge, Antony Unwin, Heike Hofmann

Department of Statistics: Faculty Publications

Parallel Coordinate Plots (PCP) are a valuable tool for exploratory data analysis of high-dimensional numerical data. The use of PCPs is limited when working with categorical variables or a mix of categorical and continuous variables. In this article, we propose Generalized Parallel Coordinate Plots (GPCP) to extend the ability of PCPs from just numeric variables to dealing seamlessly with a mix of categorical and numeric variables in a single plot. In this process we find that existing solutions for categorical values only, such as hammock plots or parsets become edge cases in the new framework. By focusing on individual observations …

Winter Field Report, Dec. 2022 - Feb. 2023, W. Ross Silcock

Nebraska Bird Review

Since this is a Winter Seasonal Report, it seems appropriate to lead off with notable reports of occurrences that might be considered unexpected for midwinter, of which there were several. A range of species was involved, suggesting an encompassing cause such as climate change. Of interest were northerly wintering groups of waterfowl including Gadwall, Green-winged Teal, Canvasback, Ringnecked Duck, and Hooded Merganser. Reports of wintering Tundra Swans, Whitewinged Doves, and Lesser Goldfinches continue to increase, and numerous Redwinged Blackbirds in the northeast in midwinter were unexpected. Also quite unexpected were two Sandhill Cranes wintering in the east, the state’s first …

The Impact Of Crop Rotation And Spatially Varying Crop Parameters In The E3sm Land Model (Elmv2), Eva Sinha, Ben Bond-Lamberty, Katherine V. Calvin, Beth A. Drewniak, Gautam Bisht, Carl Bernacchi, Bethany J. Blakely, Caitlin E. Moore

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

Earth System Models (ESMs) are increasingly representing agriculture due to its impact on biogeochemical cycles, local and regional climate, and fundamental importance for human society. Realistic large scale simulations may require spatially varying crop parameters that capture crop growth at various scales and among different cultivars, as well as common crop management practices, but their importance is uncertain, and they are often not represented in ESMs. In this study, we examine the impact of using constant versus spatially varying crop parameters using a novel, realistic crop rotation scenario in the Energy Exascale Earth System Model (E3SM) Land Model version 2 …

Remembering Paul Johnsgard, Linda R, Brown, Josef Kren

Zea E-Books Collection

Paul A. Johnsgard (1931–2021) was a friend of many, an artist, prolific author, teacher, and humble admirer of all living creatures. It was impossible to find someone at Nebraska Audubon Society or Nebraska Ornithologists’ Union meetings who did not know Paul Johnsgard. His more than 100 published books made him known not just in a community of ornithologists, birdwatchers, and bird lovers in the United States but also abroad. He was a world-renowned ornithologist and naturalist who remained deeply embedded in his local culture and its prairie environment.

We invited about 75 people to write a short memory of Paul. …

The Impact Of Sexual Violence On Women's Dating Lives: Understanding Enjoyment Of Sexualization Among Sexual Violence Survivors, Jaela Hardin

Honors Program: Senior Projects (Public)

This project seeks to understand the relationship between women’s former experiences of sexual violence and their present relationship with sex. Specifically, this study seeks to identify whether women with a history of sexual violence victimization now experience enjoyment of sexualization by others – most often men - in their daily life, as well as whether these same women also engage in self-objectification. Data from a community sample of single women aged 21-30 was collected online to record women’s responses on a variety of measures related to their sex and dating life. This project also explores whether women’s responses regarding enjoyment …

The Impact Of Parent Math Anxiety On Parent Homework Help Behaviors, Makenzie P. Starlin

Honors Program: Senior Projects (Public)

Math anxiety is commonly defined as negative feelings toward mathematics or solving mathematics problems (Dowker et al., 2016). Research indicates that math anxiety can influence parenting behaviors during homework interactions, which can involve behaviors that are autonomy supportive, or allow the child to initiate the homework task, or controlling, which does not allow the child to be actively engaged (Retanal et al., 2021) In particular, autonomy support behaviors allow children to work through homework on their own, whereas control behaviors do not allow children to work through the homework on their own and instead involve parents overseeing the homework help …

All Bark And No Byte: A Case Study On Nuclear Weapons' Role In Cyber Deterrence, Phuc Nguyen

Honors Program: Senior Projects (Public)

In what some scholars consider a marked departure from its traditional policy, the U.S.' 2018 Nuclear Deterrence Posture Review declared that the U.S. would consider the use of nuclear weapons in response to "significant, non-nuclear strategic attacks." However, despite real-world examples of the type of significant cyberattacks on U.S., allied, or partner civilian population or infrastructure alluded to in the Review, the factors that might trigger multidomain escalation remain underexplored, which creates a credibility gap in the U.S.' deterrence policy. This paper explores these factors by providing a case study of the North Korean WannaCry and Russian NotPetya cyberattacks and …

Uhpc Decked I-Beam For Accelerated Bridge Construction, George Morcous, Maher K. Tadros

Nebraska Department of Transportation: Research Reports

Ultra-High-Performance Concrete (UHPC) is an excellent material for bridge construction due to its exceptional durability and superior mechanical properties. Several Departments of Transportations (DOTs), including NDOT, have limited the use of UHPC in bridge construction to joints and connections between bridge components due to the relatively high materials cost of commercially UHPC products. Recently, NDOT has sponsored a research project to develop a non-proprietary UHPC using local materials to reduce materials cost and ensure its availability to local contractors and precast producers. The project was completed successfully and an economical UHPC mix that satisfied all workability, durability, and strength requirements …

Intensifying A Crop–Fallow System: Impacts On Soil Properties, Crop Yields, And Economics, S. J. Ruis, S. Stepanovic, Humberto Blanco-Canqui

Department of Agronomy and Horticulture: Faculty Publications

Intensifying crop–fallow systems could address increased weed control costs, increased land or rental costs, reduced crop diversity, and degraded soil properties in water-limited environments. One strategy to intensify such systems could be the insertion of a short-season crop during fallow. But, how this strategy affects soils, crop production, and farm economics needs further research. Thus, we studied the impacts of replacing fallow in a winter wheat (Triticum aestivum L)–corn (Zea mays L.)–fallow system with a short-season spring crop [field pea (Pisum sativum L.)] on crop yields and economics from 2015 to 2019 and 5-yr cumulative effects on …

Project Avatar: Utilizing The Power Of Social-Media To Share Stories Of Hope, Elizabeth Cremins

Honors Program: Senior Projects (Public)

Addiction affects everyone and the stigma around addiction and its’ recovery makes it exponentially harder for individuals to heal. Today, adolescents are exposed to drugs, alcohol, and related substances from younger ages than ever before and the age of first consumption of these substances is continually decreasing. Further, social media makes it easier than ever for these young people to see substance-related content. Most teens and young adults today check their social media daily—if not hourly. Due to the young age of first exposure to substances coupled with the near-constant exposure that social media provides, addiction is an ever-present problem …

An Exploratory Study Of How Measuring Knowledge-In-Use Adds Value Beyond Static Knowledge Measures, Julie Dwyer, Rachel E. Schachter, Alessandra E. Ward

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

Research-supported knowledge about how children develop language is considered foundational for high-quality instruction and as such, measuring and developing teachers’ knowledge has been emphasized across the field of early childhood. However, there is a critical gap in understanding how this static knowledge gained through pre-service and in-service experiences is connected to enacted practice. To address this, we compared teachers’ static knowledge regarding language development as assessed via a traditional paper and pencil measure with their knowledge used in-the-moment during language interactions with children via stimulated recall interviews. Ten educators from a variety of early childhood programs completed the surveys and …

How Gender And Primary Language Influence The Acquisition Of Economic Knowledge Of Secondary School Students In The United States And Germany, Roland Happ, Susanne Schmidt, Olga Zlatkin-Troitschanskaia, William Walstad

Department of Economics: Faculty Publications

Economics has become an essential component of secondary school curricula in many countries as a result of the growing awareness that young adults need fundamental economic knowledge to manage their personal finances. Accordingly, an increasing number of comparative studies are being conducted of commonalities and differences in students’ economic knowledge and its most decisive influencing factors within and across countries. In this study, we compare the performance of secondary school students in the United States (N = 3517) and Germany (N = 983) on the fourth version of the Test of Economic Literacy. We investigate two personal characteristics that have …

Editorial: Structure And Function Of Chloroplasts, Volume Iii, Hongbo Gao, Alistair J. Mccormick, Rebecca Roston, Yan Lu

Department of Biochemistry: Faculty Publications

Chloroplasts are endosymbiotic organelles derived from cyanobacteria. They have a double envelope membrane, including the outer envelope and the inner envelope. A complex membrane system, thylakoids, exists inside the chloroplast. It is the site of the light-dependent reactions of photosynthesis. The stroma is the main site of the carbon fixation reactions. Although photosynthesis is a very complicated process with many proteins involved, there are many other important processes that occur in chloroplasts, including the regulation of photosynthesis, the biogenesis and maintenance of the structures, carbohydrate, lipid, tetrapyrrole, amino acid, and isoprenoid metabolism, production of some phytohormones, production of specialized metabolites, …

Nelson

Department of Agricultural and Biological Systems Engineering: Faculty Publications

While the eddy covariance (EC) technique is a well-established method for measuring water fluxes (i.e., evaporation or 'evapotranspiration’, ET), the measurement is susceptible to many uncertainties. One such issue is the potential underestimation of ET when relative humidity (RH) is high (>70%), due to low-pass filtering with some EC systems. Yet, this underestimation for different types of EC systems (e.g. open-path or closed-path sensors) has not been characterized for synthesis datasets such as the widely used FLUXNET2015 dataset. Here, we assess the RH-associated underestimation of latent heat fluxes (LE, or ET) from different EC systems for 163 sites in …

Arnett, John Paul V. Anders, Tyler J. Neltner, Dolores G. Ortega, Richard J. Schmidt, Glen O. Johnson

Department of Nutrition and Health Sciences: Faculty Publications

Purpose The purpose of the present study was to examine the interactions between perceived fatigability and performance fatigability in women and men by utilizing the RPE-Clamp model to assess the fatigue-induced effects of a sustained, isometric forearm flexion task anchored to RPE = 8 on time to task failure (TTF), torque, and neuromuscular responses.

Methods Twenty adults (10 men and 10 women) performed two, 3 s forearm flexion maximal voluntary isometric contractions (MVICs) followed by a sustained, isometric forearm flexion task anchored to RPE = 8 using the OMNI-RES (0–10) scale at an elbow joint angle of 100°. Electromyographic amplitude …

Two Qtls Govern The Resistance To Sclerotinia Minor In An Interspecific Peanut Ril Population, Melina H. Rosso, Francisco J. De Blas, Alicia N. Massa, Claudio Oddino, Damian F. Giordano, Jose G. Seijo, Renee S. Arias, Juan H. Soave, Sara J. Soave, Mario I. Buteler, Marina Bressano

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

Sclerotinia blight is a soilborne disease caused by Sclerotinia minor Jagger and can produce severe decrease in yield. Cultural management strategies and chemical treatment are not completely effective; therefore, growing peanut-resistant varieties is likely to be the most effective control method for this disease. Sclerotinia blight resistance has been identified in wild Arachis species and further transferred to peanut elite cultivars. To identify the genome regions conferring Sclerotinia blight resistance within a tetraploid genetic background, this study evaluated a population of recombinant inbred lines (RIL) with introgressed genes from three wild diploid species: A. cardenasii, A. correntina, and A. batizocoi. …

Evaluating Metabolic And Genomic Data For Predicting Grain Traits Under High Night Temperature Stress In Rice, Ye Bi, Rafael Massahiro Yassue, Puneet Paul, Balpreet Kaur Dhatt, Jaspreet Sandhu, Phuc Thi Do, Harkamal Walia, Toshihiro Obata, Gota Morota

Department of Agronomy and Horticulture: Faculty Publications

The asymmetric increase in average nighttime temperatures relative to increase in average daytime temperatures due to climate change is decreasing grain yield and quality in rice. Therefore, a better genome-level understanding of the impact of higher night temperature stress on the weight of individual grains is essential for future development of more resilient rice. We investigated the utility of metabolites obtained from grains to classify high night temperature (HNT) conditions of genotypes, and metabolites and single-nucleotide polymorphisms (SNPs) to predict grain length, width, and perimeter phenotypes using a rice diversity panel. We found that the metabolic profiles of rice genotypes …

Global Three-Dimensional Water Vapor Feature-Tracking For Horizontal Winds Using Hyperspectral Infrared Sounder Data From Overlapped Tracks Of Two Satellites, Amir Ouyed, Nadia Smith, Xubin Zeng, Thomas Galarneau Jr., Hui Su, Ross D. Dixon

Department of Earth and Atmospheric Sciences: Faculty Publications

The lack of measurements of three-dimensional (3D) distribution of horizontal wind vectors is a major challenge in atmospheric science. Here, we develop an algorithm to retrieve winds for nine pressure levels at 1° grid spacing from 70°N to 70°S. The retrieval is done by tracking water vapor from the hyperspectral Cross-track Infrared Sounder aboard two polar satellites (NOAA-20 and Suomi-NPP) that have overlapped tracks separated by 50 min. We impose a gross error check by flagging retrievals that are too different from ERA-5 reanalysis. Testing the algorithm for the first week of January and July 2020 indicates that our algorithm …

Alfalfa In Rotation With Annual Crops Reduced Nitrate Leaching Potential, Arshdeep Singh, Tahseen Afzal, Bryan Woodbury, Charles Wortmann, Javed Iqbal

Department of Agronomy and Horticulture: Faculty Publications

Rotation of perennial alfalfa (Medicago sativa L.) with annual crops has the potential to reduce nitrate-nitrogen (NO₃-N) in the vadose zone and increase soil organic carbon (SOC) sequestration. The objective of this study was to determine the long-term effects on SOC, NO₃-N, ammonium-N (NH₄-N), and soil water in the 7.2 m depth with an alfalfa rotation compared with continuous corn (Zea mays L.). Soils from six pairs of alfalfa rotation versus continuous corn observation points were sampled to 7.2 m depth in 0.3 m increments. The uppermost 0.3 m was divided into …

How Administration Stakes And Settings Affect Student Behavior And Performance On A Biology Concept Assessment, Crystal Uminski, Joanna K. Hubbard, Brian A. Couch

School of Biological Sciences: Faculty Publications

Biology instructors use concept assessments in their courses to gauge student understanding of important disciplinary ideas. Instructors can choose to administer concept assessments based on participation (i.e., lower stakes) or the correctness of responses (i.e., higher stakes), and students can complete the assessment in an in-class or out-of-class setting. Different administration conditions may affect how students engage with and perform on concept assessments, thus influencing how instructors should interpret the resulting scores. Building on a validity framework, we collected data from 1578 undergraduate students over 5 years under five different administration conditions. We did not find significant differences in scores …

Population Dynamics And Harvest Management Of Eastern Mallards, Anthony J. Roberts, Jeffrey A. Hostetler, Joshua C. Stiller, Patrick K. Devers, William A. Link

United States Fish and Wildlife Service: Publications

Managing sustainable harvest of wildlife populations requires regular collection of demographic data and robust estimates of demographic parameters. Estimates can then be used to develop a harvest strategy to guide decision‐making. Mallards (Anas platyrhynchos) are an important species in the Atlantic Flyway for many users and they exhibited exponential growth in the eastern United States between the 1970s and 1990s. Since then, estimates of mallard abundance have declined 16%, prompting the Atlantic Flyway Council and United States Fish and Wildlife Service to implement more restrictive hunting regulations and develop a new harvest strategy predicated on an updated population …
