Specialized Late Cingulo-Opercular Network Activation Elucidates The Mechanisms Underlying Decisions About Ambiguity, Jordan E. Pierce, Nathan M. Petro, Elizabeth Clancy, Caterina Gratton, Steven E. Petersen, Maital Neta

Center for Brain, Biology, and Behavior: Faculty Publications

Cortical task control networks, including the cingulo-opercular (CO) network play a key role in decision-making across a variety of functional domains. In particular, the CO network functions in a performance reporting capacity that supports successful task performance, especially in response to errors and ambiguity. In two studies testing the contribution of the CO network to ambiguity processing, we presented a valence bias task in which masked clearly and ambiguously valenced emotional expressions were slowly revealed over several seconds. This slow reveal task design provides a window into the decision-making mechanisms as they unfold over the course of a trial. In …

A Collaborative Model For Faculty Development: Helping Faculty Develop Inclusive Teaching Practices, Christina Bifulco, Christopher Drue

To Improve the Academy: A Journal of Educational Development

Inclusive pedagogy, an intentional approach to creating learning environments that meet the instructional needs of diverse student populations, is critically important and a moral imperative in contemporary higher education. Among the biggest challenges for creating faculty development programming to address the development and use of inclusive pedagogy are the lack of financial resources to support the effort and a lack of centralized institutional staff expertise and resources to inform and support such efforts. This case study gives a model for an institutional collaboration that incorporates experts from a variety of offices to deliver a series of inclusive teaching workshops and …

Developing Critical Literacy: An Urgent Goal, Victoria Appatova, Alice Horning

To Improve the Academy: A Journal of Educational Development

Due to the recent changes in higher education, including a major shift to online learning and the reform of education, critical literacy skills of today’s generation of college students face the peril of an increasing decline. All students, developmental and non-developmental in online and face-to-face environments, need the well-organized, systemic effort of college educators to enhance students’ critical literacy, including critical thinking, reading, writing, and research skills taught in an integrated manner. To promote postsecondary critical literacy, the Professional and Organizational Development (POD) Network and centers for teaching and learning (CTLs) can expand collaborations with existing “writing across the curriculum …

An Exploration Of Trauma-Inclusive Pedagogy And Students’ Perceptions Of Academic Success, R. Jason Lynch, Krista Wojdak

To Improve the Academy: A Journal of Educational Development

While trauma-inclusive approaches to student learning have been well documented in K–12 contexts, postsecondary education has done little to incorporate trauma-inclusive pedagogy into college classrooms. Using a sample (n = 529) of graduate and undergraduate students at a public rural-serving regional serving university, this study aims to explore differences in students’ perception of academic success in courses where trauma-inclusive practices were used and courses where these practices were not. Findings provide evidence that students felt more successful in courses where trauma-inclusive practices were used. Additionally, researchers were able to demonstrate that differences in perceptions of success were more pronounced …

Exploring The Impact Of Student-Faculty Partnership Program At A Hispanic Serving Institution, Alyssa Guadalupe Cavazos, Lesley Chapa, Javier Cavazos-Vela

To Improve the Academy: A Journal of Educational Development

Guided by a strength-based framework and counter-storying lens, we use a qualitative case study approach (Cook-Sather, 2020; Cook-Sather and Motz-Storey, 2016; Lechuga-Peña and Lechuga, 2018) to explore students’ and instructors’ experiences with a students as learners and teachers (SaLT) partnership program at a Hispanic Serving Institution (HSI). This study includes five students and five faculty members who participated in the student-faculty partnership program. Data collection involved student partners’ self-assessment reflections and faculty members’ pre- and post-program reflections on their experiences. Several themes were identified following a phenomenological analysis of students’ and faculty partners’ self-reflections. Themes emerging from student participants included …

How Teachers Use Data: Description And Differences Across Prek Through Third Grade, Amanda Witte, Lisa Knoche, Susan Sheridan, Natalie A. Koziol

Nebraska Center for Research on Children, Youth, Families, and Schools: Faculty Publications

The use of data to inform instruction has been linked to improved student outcomes, early identification of intervention needs, and teacher decision-making and efficacy. Additionally, data are used as a means of accountability within educational settings. However, little is known about data use practices among early grades teachers. The purpose of the current study is to describe the data use of PreK to third grade teachers and to investigate differences in data use and support across grade levels. Participants were 307 early childhood teachers in PreK and early elementary school. Analysis of survey data revealed, overall, most teachers across grade …

Optimizing Crop Productivity And Fertility Practices In Intermediate Wheatgrass, Roberta Bianchin Rebesquini

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

The intensive management associated with many annual crops often includes recurring tillage, fertilization, and pesticide applications, which contribute to environmental concerns such as water pollution and soil erosion. Intermediate wheatgrass (Thinopyrum intermedium), recognized under the trade name Kernza®, is a perennial grass that can be managed to produce grain and biomass while providing desired environmental benefits such as soil conservation and nutrient cycling. There has been limited research on best management practices and crop productivity for this alternative dual-use crop in Nebraska. A field experiment was conducted beginning in 2021 to assess nitrogen (N), phosphorus (P), and potassium …

Honors Program: Senior Projects (Public)

Dunkin Brands is the parent company that operates franchises, and one of its most well-known subsidiaries is Dunkin' Donuts. This establishment, rooted in the United States but with a global presence, is a significant player in the coffee and donut shop industry. This paper provides a background on Dunkin Brands and analyzes their internal and external environment, firm strategy, and corporate governance. The analysis uses theories and principles learned in management, such as Porter’s Five Forces and PESTEL analysis. Additionally, strategic recommendations were made for Dunkin Brands' next steps to continue dominating the coffee and donut shop industry.

Limited Accumulation And Persistence Of An Influenza A Virus In Tadpole Snails (Physa Spp.), Paul T. Oesterle, J. Jeffrey Root, Darcy S.O. Mora, Heather Schneider, Alan B. Franklin, Kathryn P. Huyvaert

United States Department of Agriculture Wildlife Services: Staff Publications

Waterfowl infected with avian influenza A viruses (IAVs) shed infectious virus into aquatic environments, providing a mechanism for transmission among waterfowl, while also exposing the entire aquatic ecosystem to the virus. Aquatic invertebrates such as freshwater snails are likely exposed to IAVs in the water column and sediment. Freshwater snails comprise a significant portion of some waterfowl species’ diets, so this trophic interaction may serve as a novel route of IAV transmission. In these experiments, tadpole snails (Physa spp.) were exposed to a low-pathogenicity IAV (H3N8) to determine whether snails can accumulate the virus and, if so, how long virus …

Upscaling Wetland Methane Emissions From The Fluxnet-Ch4 Eddy Covariance Network (Upch4 V1.0): Model Development, Network Assessment, And Budget Comparison, Gavin Mcnicol, Etienne Fluet-Chouinard, Zutao Ouyang, Sara Knox, Zhen Zhang, Tuula Aalto, Sheel Bansal, Kuang Yu Chang, Min Chen, Kyle Delwiche, Sarah Feron, Mathias Goeckede, Jinxun Liu, Avni Malhotra, Joe R.

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Wetlands are responsible for 20%–31% of global methane (CH4) emissions and account for a large source of uncertainty in the global CH4 budget. Data-driven upscaling of CH4 fluxes from eddy covariance measurements can provide new and independent bottom-up estimates of wetland CH4 emissions. Here, we develop a six-predictor random forest upscaling model (UpCH4), trained on 119 site-years of eddy covariance CH4 flux data from 43 freshwater wetland sites in the FLUXNET-CH4 Community Product. Network patterns in site-level annual means and mean seasonal cycles of CH4 fluxes were reproduced accurately in tundra, boreal, and temperate regions (Nash-Sutcliffe Efficiency ∼0.52–0.63 and 0.53). …

Creating An Automatic Lowering Function For Quarter-Scale Tractor Pulling Sled, Sam Wilkins

Honors Program: Senior Projects (Public)

As the agricultural industry works to continuously integrate innovative technology and improve production efficiency, improved on-board data acquisition and transmission will be necessary for all agricultural machines. To make this a reality, the utilization of controller area network (CAN) technology will be crucial. Therefore, it is important for all agricultural engineers to have foundational knowledge of CAN bus systems and the standards that govern their use in industry. The UNL quarter-scale tractor team regularly utilizes CAN buses on their tractors and testing equipment. One such testing machine is the team’s pulling sled, which uses CAN messages to transport important information …

Did Cover Crop Or Animal Manure Ameliorate Corn Residue Removal Effects On Soil Mechanical Properties After 10 Years?, Hans W. Klopp, Humberto Blanco-Canqui, Michael Sindelar, Virginia L. Jin, Marty R. Schmer, Richard B. Ferguson

Department of Agronomy and Horticulture: Faculty Publications

Crop residue removal may negatively affect soil mechanical properties, which are key components of soil quality. To evaluate potential long-term effects, we assessed the 10-yr impact of corn (Zea mays L.) residue removal (59 % of non-grain biomass annually) on surface soil mechanical properties (0–20 cm). We also evaluated whether adding carbon (C) amendments, such as using a winter rye (Secale cereale L.) cover crop or surface-applying cattle manure (24 Mg ha− 1 biannually) can ameliorate the effects of crop residue removal. This long-term study was under irrigated no-till continuous corn on a silt loam soil in south-central …

The Pepsis Menechma Lepeletier (Hymenoptera: Pompilidae: Pepsinae) Taxonomic And Nomenclatural Problem, Frank E. Kurczewski

Insecta Mundi

Hurd (1952), in revising the Nearctic species of Pepsis Fabricius, separated P. cerberus Lucas from P. elegans Lepeletier based on external morphology and geography. Vardy (2005), in his Western Hemisphere Pepsis revision, combined these taxa and several Neotropical color and structural variants in a broad defini­tion of P. menechma Lepeletier extending across ~11,250 km and two continents. Vardy (2005) synonymized the familiar and well-documented, 160-year-old P. elegans under P. menechma probably because it appeared several pages later in Lepeletier’s (1845) Histoire Naturelle des Insectes. Hyménoptères. Vardy’s (2005) interpre­tation of Pepsis menechma as a viable species presents a taxonomic and …

First Measurement Of The Forward Rapidity Gap Distribution In PPb Collisions At √SNn=8.16 Tev, A. Tumasyan

Kenneth Bloom Publications

For the first time at LHC energies, the forward rapidity gap spectra from proton-lead collisions for both proton and lead dissociation processes are presented. The analysis is performed over 10.4 units of pseudorapidity at a center-of-mass energy per nucleon pair of √s_NN = 8.16 TeV, almost 300 times higher than in previous measurements of diffractive production in proton-nucleus collisions. For lead dissociation processes, which correspond to the pomeron-lead event topology, the EPOS-LHC generator predictions are a factor of 2 below the data, but the model gives a reasonable description of the rapidity gap spectrum shape. For the pomeron-proton …

Gender Differences In Graduate Student Views On The Professional Climate In Economics, Ann Mari May, Mary G. Mcgarvey, Muazzam Toshmatova

Department of Economics: Faculty Publications

This research examines graduate student's views on the professional climate in economics using a comprehensive survey of students enrolled in economics Ph.D. programs in the United States. Topics discussed include stress and work/life balance, disciplinary climate in the profession, departmental climate, and the prevalence of sexual harassment. We find significant gender differences in views on all four topics—particularly in views on departmental climate and disciplinary climate in the profession. We analyze the results based on gender, rank of the institution, public versus private institutional status, and representation of women faculty in departments.

Resistance Training In Humans And Mechanical Overload In Rodents Do Not Elevate Muscle Protein Lactylation, Madison L. Mattingly, Auburn University A. Ruple, Casey L. Sexton, Joshua S.

Brooks Mobley, Ivan Jose Vechetti Jr, Christopher G. Vann, Michael D. Roberts

Department of Nutrition and Health Sciences: Faculty Publications

Although several reports have hypothesized that exercise may increase skeletal muscle protein lactylation, empirical evidence in humans is lacking. Thus, we adopted a multifaceted approach to examine if acute and subchronic resistance training (RT) altered skeletal muscle protein lactylation levels. In mice, we also sought to examine if surgical ablation-induced plantaris hypertrophy coincided with increases in muscle protein lactylation. To examine acute responses, participants’ blood lactate concentrations were assessed before, during, and after eight sets of an exhaustive lower body RT bout (n = 10 trained college-aged men). Vastus lateralis biopsies were also taken before, 3-h post, and 6-h post-exercise …

The Localization Of Centromere Protein A Is Conserved Among Tissues, Eleonora Cappelletti, Francesca M. Piras, Lorenzo Sola, Marco Santagostino, Jessica L. Petersen, Rebecca R. Bellone, Carrie J. Finno, Sichong Peng, Ted S. Kalbfleisch, Ernest Bailey, Solomon G. Nergadze, Elena Giulotto

Department of Animal Science: Faculty Publications

Centromeres are epigenetically specified by the histone H3 variant CENP-A. Although mammalian centromeres are typically associated with satellite DNA, we previously demonstrated that the centromere of horse chromosome 11 (ECA11) is completely devoid of satellite DNA. We also showed that the localization of its CENP-A binding domain is not fixed but slides within an about 500 kb region in different individuals, giving rise to positional alleles. These epialleles are inherited as Mendelian traits but their position can move in one generation. It is still unknown whether centromere sliding occurs during meiosis or during development. Here, we first improve the sequence …

Toward A Brighter Future For Entomological Collections, Susan Weller

University of Nebraska State Museum: Entomology Papers

Entomology collections, and natural history collections more generally, are critical research infrastructure. Specimens and metadata such as specimen labels, field notebooks, images, dissections, genetic sequences, and host plant data (to name a few) enable team science to examine biological diversity through time and study the impacts of humans on landscapes and climate (Johnson et al. 2023). However, some do not grasp the connection between drawers of insect specimens and modern science driven by advances in computational methods, molecular biology, and big data. Scientific specimens are key to connecting large-scale research questions within and among entomology and other disciplines.

Measurement Of The Dependence Of The Hadron Production Fraction Ratios F S/F U And F D/F U On B Meson Kinematic Variables In Proton-Proton Collisions At √S=13 Tev, A. Tumasyan

Department of Physics and Astronomy: Faculty Publications

The dependence of the ratio between the B⁰_s and B⁺ hadron production fractions, f_s/f_u, on the transverse momentum (p_T) and rapidity of the B mesons is studied using the decay channels B⁰_s → J/ψϕ and B⁺ → J/ψK⁺. The analysis uses a data sample of proton-proton collisions at a center-of-mass energy of 13 TeV, collected by the CMS experiment in 2018 and corresponding to an integrated luminosity of 61.6 fb⁻¹. The f_s/f_u ratio is observed to depend on the B …
