A Machine-Learning Approach To Predicting The Achievement Of Australian Students Using School Climate; Learner Characteristics; And Economic, Social, And Cultural Status, Myint S. Khine, Yang Liu, Vivek K. Pallipuram, Ernest Afari

Pacific Faculty Work

The Programme for International Student Assessment (PISA) is a global survey conducted by the Organisation for Economic Co-operation and Development (OECD) to assess educational systems by evaluating the academic performance of 15-year-old school students in mathematics, science, and reading. In PISA 2022, 13,437 students from Australia participated in the test. While the PISA main questionnaire assesses the subject knowledge, the student background questionnaire solicits contextual information such as school climate, learner characteristics, and socioeconomic status. This study analyses how these contextual variables predict student achievement using the machine-learning models Ridge Linear Regression, K-Nearest Neighbours, Decision Trees, eXtreme Gradient Boosting, and …

First Breeding Confirmation For Red-Breasted Nuthatch (Sitta Canadensis) Along The Big Bend Reach Of The Platte River, Jacob C. Cooper, Cody Mcgregor, Letitia M. Reichart, Janet Steele

Nebraska Bird Review

The Red-breasted Nuthatch (Sitta canadensis) is a highly nomadic species of North American nuthatch prone to large movements across the entire continent (Ghalambor and Martin 2020). This behavior has resulted in both a lack of geographic variation across the continent and propensity to colonize isolated patches of suitable habitat (Ghalambor and Martin 2020). In the Bessey District of the Nebraska National Forest (NNF), Red-breasted Nuthatches were one of the first coniferous-forest bird species to colonize and begin breeding in the isolated planted stands of pine (Zimmer 1913, Bray 1994). Despite the increasing number of records for the species …

Fall Field Report, August–November 2024, W. Ross Silcock

Nebraska Bird Review

First off, I should reiterate that records are only mentioned in this Introduction and in the text when they add to or fine-tune data included in BONO (Birds of Nebraska – Online (outdoornebraska.gov). It was my expectation that as the number of birders and in particular those reporting to eBird continue to increase, gaps in the database will be filled and my job will become simpler. However, this expectation is yet to be realized, likely due to increasing movements and activity among birds that appears to be due to increasing severity of weather events, such as heat, cold, and drought, …

Hypervalent Iodine Based Macrocycles And Their Supramolecular Interactions With Guests, Krishna Pandey

Dissertations

In this contribution, we successfully synthesize different variations of hypervalent iodine macrocycles (HIM) including novel phenylalanine base HIM. Next, this study explores the dynamic self-assembly and disassembly of hypervalent iodine-based macrocycles (HIMs) guided by secondary bonding interactions. The reversible disassembly and reassembly of HIMs are facilitated through anion binding via addition of tetrabutylammonium (TBA) salts or removal of the anion by addition of silver nitrate. The association constants for HIM monomers with TBA(Cl) and TBA(Br) are calculated and show a correlation with the strength of the iodine-anion bond. A unique tetracoordinate hypervalent iodine-based compound was identified as the disassembled monomer. …

Modulation Of Piezo Mechanosensors: Exploring The Effects Of Proteinogenic Sulfur-Containing Amino Acids And Propofol, Donggyeom Yu

Dissertations

Organisms are constantly subjected to mechanical stimuli originating from their environment or internal activities. To sense and properly handle such mechanical cues, the conversion of mechanical signals into electrochemical signals occurs continuously within the organisms. Mechanosensitive ion channels (MSCs) are pivotal participants in this process, being ready to open to allow the movement of ions across cellular membranes in response to mechanical stimulation. Piezo1 and Piezo2 mechanosensitive cation channels are evolutionarily conserved MSCs, taking part in various physiological processes, including bone formation and touch sensation. Mutations in Piezo1 or Piezo2 lead to pathological conditions and overexpression of the channels is …

Citation Bias, Diversity, And Ethics, Keisha S Ray, Perry Zurn, Jordan D Dworkin, Dani S Bassett, David B Resnik

Faculty and Staff Publications

How often a researcher is cited usually plays a decisive role in that person's career advancement, because academic institutions often use citation metrics, either explicitly or implicitly, to estimate research impact and productivity. Research has shown, however, that citation patterns and practices are affected by various biases, including the prestige of the authors being cited and their gender, race, and nationality, whether self-attested or perceived. Some commentators have proposed that researchers can address biases related to social identity or position by including a Citation Diversity Statement in a manuscript submitted for publication. A Citation Diversity Statement is a paragraph placed …

Observing Dynamic Emotional Faces From Many Generations, Tashaunda Grimmett

Masters Theses & Specialist Projects

This study sought to further understand emotion perception capabilities in younger and older adults. Previous studies examining emotion perception have consistently found emotion recognition deficits with age. The most common technique used to investigate age differences in emotion perception is a label selection task that presents static images of actors expressing emotion. More recently, dynamic stimuli have been developed; they portray realistic facial expressions that are more comparable to what one sees in real life. The use of dynamic stimuli has been found to ameliorate most age differences in the recognition of basic emotion categories. The current study presented dynamic …

Evaluation Of Biochar As A Remediation Tool For Aminopyralid Contaminated Compost, Steven James Parris

Masters Theses & Specialist Projects

Aminopyralid is a synthetic auxin herbicide which is applied to grass pastures to control broadleaf weed populations. Aminopyralid can contaminate compost through inputs derived from treated pastures such as manure and grass clippings. This possibility poses the threat of inadvertent herbicide exposure to sensitive vegetable plants through using compost contaminated with aminopyralid. Biochar can absorb pollutants and has a synergistic effect with compost when applied to the compost mixture. This study examined the relationship between biochar and aminopyralid through compost consisting of dairy manure and sawdust 1:1 mixture, aminopyralid (10μg/kg), and biochar at four treatment levels of total mass of …

The Atheroprotective Impact Of Anti-Mir-33a-5p/3p In Cultured Pro-Inflammatory Endothelial Cells, Kun Huang

All Dissertations

Atherosclerosis is the process of cholesterol buildup within arterial cells, which is considered a leading factor that causes certain cardiovascular diseases. Cholesterol accumulation within pro-inflammatory endothelial cells is thought to induce atherogenesis and accelerate atherosclerosis progression. Evidence suggests inhibiting the microRNA miR-33a in arterial cells may promote atheroprotection via increasing ABCA1 protein expression. MiR-33a is processed into two functional strands, miR-33a-5p and miR-33a-3p. The potential atheroprotective effect of inhibiting miR-33a-5p and/or miR-33a-3p precisely in pro-inflammatory endothelial cells is not fully understood, as data is scant regarding what potential atheroprotective impact ABCA1-dependent cholesterol within pro-inflammatory endothelial cells demonstrates, which occurs via …

Challenging Myths & Addressing Intimate Partner Sexual Violence In Lgbtq+ Relationships, Nora K. Whitten

SPARK Symposium Presentations

Intimate partner violence (IPV), including intimate partner sexual violence (IPSV), is a public health crisis that disproportionately affects members of the LGBTQ+ community. This paper draws upon related, though limited, research to identify the five prevalent myths surrounding IPSV in LGBTQ+ relationships, addressing the following misconceptions: 1) IPSV can only occur in heterosexual relationships, 2) IPSV in LGBTQ+ relationships is not as severe, 3) Women cannot commit acts of sexual violence, 4) The more “masculine” partner is always the perpetrator, and 5) IPSV is a “mutual fight” among partners of the same sex. These myths perpetuate victim-blaming, minimize the severity …

Leveraging Geo-Ai To Evaluate Conservation Land Conditions In Nebraska, Usa, Fnu Jahangeer

Community and Regional Planning Program: Theses

Wetlands are among the most vital natural resources, offering extensive ecosystem services that benefit human societies. However, human activities and disturbances have led to widespread wetland degradation and loss worldwide. Key factors contributing to this degradation include pollution, exploitation of biological resources, modifications to natural systems, and agricultural and aquacultural practices. This study examines wetland conservation efforts in Nebraska, focusing on three main areas: (1) AI-Driven Applications in Google Earth Engine for Surface Water Monitoring, Assessment, and Management; (2) Assessing Wetland Hydrological Performance under Three Conservation Programs in Nebraska through AI-Driven Google Earth Engine Analysis; and (3) Identifying Potential Wetland …

Scavenging As An Accelerant In The Postmortem Interval Estimate: Refining Quantitative Regressions For Decomposition Analyses In Southeast Nebraska, Jenna L. Alexander

Department of Anthropology: Theses and Student Research

In forensic anthropology, the postmortem interval (PMI) is an estimation of the time elapsed from the moment of death to the point of discovery or examination. Contemporary approaches for estimating PMI have sought to refine broad quantitative regressions by addressing variance among intrinsic and extrinsic influences of decomposition at a regional level. Southeast Nebraska and the broader Great Plains region encompass one of the most influential agricultural ecosystems, featuring a unique climate type and a diverse spectrum of vertebrate scavengers. While there has been minimal research addressing how the biogeoclimatic conditions of Nebraska affect predicted estimates for PMI using known …

Weighing In: Why Obesity Should Be Considered A Qualifying Disability Under The Americans With Disabilities Act, Anne Marie Hawley

University of Chicago Law Review

Anti-fat bias has been described as the last socially acceptable form of prejudice. Weight discrimination persists even though obesity affects over 100 million adults in the United States and obesity rates have continued climbing over the past few decades. Despite the discrimination that fat people face, there is no federal protection against weight discrimination. One potential solution to the lack of existing legal protections is the Americans with Disabilities Act (ADA).

Claimants challenging weight discrimination under the ADA argue that weight discrimination is a form of disability discrimination—namely, discrimination based on the medical condition of obesity. Although the medical community …

The Primate Gut Microbiota Contributes To Interspecific Differences In Host Metabolism., Elizabeth K Mallott, Sahana Kuthyar, Won Lee, Derek Reiman, Hongmei Jiang, Sriram Chitta, E Alexandria Waters, Brian T Layden, Ronen Sumagin, Laura D Manzanares, Guan-Yu Yang, Maria Luisa Savo Sardaro, Stanton Gray, Lawrence E Williams, Yang Dai, James P Curley, Chad R Haney, Emma R Liechty, Christopher W Kuzawa, Katherine R Amato

Faculty Research 2024

Because large brains are energetically expensive, they are associated with metabolic traits that facilitate energy availability across vertebrates. However, the biological underpinnings driving these traits are not known. Given its role in regulating host metabolism in disease studies, we hypothesized that the gut microbiome contributes to variation in normal cross-vertebrate species differences in metabolism, including those associated with the brain's energetic requirements. By inoculating germ-free mice with the gut microbiota (GM) of three primate species - two with relatively larger brains and one with a smaller brain - we demonstrated that the GM of larger-brained primates shifts host metabolism towards …

Faculty Research 2024

To gain insight into how researchers of aging perceive the process they study, we conducted a survey among experts in the field. While highlighting some common features of aging, the survey exposed broad disagreement on the foundational issues. What is aging? What causes it? When does it begin? What constitutes rejuvenation? Not only was there no consensus on these and other core questions, but none of the questions received a majority opinion-even regarding the need for consensus itself. Despite many researchers believing they understand aging, their understanding diverges considerably. Importantly, as different processes are labeled as "aging" by researchers, different …

Lessons Learned From 20 Years Of Preclinical Testing In Pediatric Cancers., Malcolm A Smith, Peter J Houghton, Richard B Lock, John M Maris, Richard Gorlick, Raushan T Kurmasheva, Xiao-Nan Li, Beverly A Teicher, Jeffrey Chuang, Filemon S Dela Cruz, Michael A Dyer, Andrew L Kung, Michael W Lloyd, Yael P Mossé, Timothy M Stearns, Elizabeth A Stewart, Carol J Bult, Stephen W Erickson

Faculty Research 2024

Programs for preclinical testing of targeted cancer agents in murine models of childhood cancers have been supported by the National Cancer Institute (NCI) since 2004. These programs were established to work collaboratively with industry partners to address the paucity of targeted agents for pediatric cancers compared with the large number of agents developed and approved for malignancies primarily affecting adults. The distinctive biology of pediatric cancers and the relatively small numbers of pediatric cancer patients are major challenges for pediatric oncology drug development. These factors are exacerbated by the division of cancers into multiple subtypes that are further sub-classified by …

The Interplay Of Covid 19, Organized Religion, And Social Media: “How Can I Be The Person I Feel I Need To Be?”, White Dove Bryant Beethoven Keith Short

All-Inclusive List of Electronic Theses and Dissertations

Young adults are disaffiliating themselves from organized religion (Hout & Fischer, 2014). This study investigates the impact of social media use on religious identity, teaching, and learning. Social media use is changing young adults as individuals in worldview and perspective, spirituality, religion, and personal lifestyle (Schaeffer, 2019). Messages devised for young adults by Christian ministers for discipleship in teaching and instruction are inharmonious with young adults and their personal views of the world, how to live, and religion (Pew Research Center, 2019). The continued existence of religious teaching, congregant replenishment, and practice of the organized institutional Christian church within society …

Biological Sciences Faculty Publications

Hundreds of studies have explored student evolution acceptance because evolution is a core concept of biology that many undergraduate biology students struggle to accept. However, this construct of “evolution acceptance” has been defined and measured in various ways, which has led to inconsistencies across studies and difficulties in comparing results from different studies. Many studies and essays have offered evaluations and perspectives of evolution acceptance instruments, but publications with a focus on consensus building across research teams is still needed. Further, little attention has been paid to how evolution acceptance instruments may be interpreted differently by students with varied religious …

Interspecific Selection In A Diverse Mycorrhizal Symbiosis, Megan A. Rúa, Jason D. Hoeksema

Biological Sciences Faculty Publications

Coevolution describes evolutionary change in which two or more interacting species reciprocally drive each other’s evolution, potentially resulting in trait diversification and ecological speciation. Much progress has been made in analysis of its dynamics and consequences, but relatively little is understood about how coevolution works in multispecies interactions, i.e., those with diverse suites of species on one or both sides of an interaction. Interactions among plant hosts and their mutualistic ectomycorrhizal fungi (ECM) may provide an ecologically unique arena to examine the nature of selection in multispecies interactions. Using native genotypes of Monterey pine (Pinus radiata), we performed a common …

Transcription Factor Expression Landscape In Drosophila Embryonic Cell Lines, Robert A. Drewell, Daniel Klonaros, Jacqueline Dresch

Biology

Background: Transcription factor (TF) proteins are a key component of the gene regulatory networks that control cellular fates and function. TFs bind DNA regulatory elements in a sequence-specific manner and modulate target gene expression through combinatorial interactions with each other, cofactors, and chromatin-modifying proteins. Large-scale studies over the last two decades have helped shed light on the complex network of TFs that regulate development in Drosophila melanogaster. Results: Here, we present a detailed characterization of expression of all known and predicted Drosophila TFs in two well-established embryonic cell lines, Kc167 and S2 cells. Using deep coverage RNA sequencing approaches we …

On Humans, Hogs, And Habitat: How Landscape Features And Vegetation Influence Wild Hog (Sus Scrofa) Detection On Private Lands And Using Existing Wild Hog Outreach Websites To Create An Effective Website For South Carolina, Andrew Jamison

All Theses

Invasive species are a source of human conflict with wildlife on a global scale and exist to the detriment of native wildlife species. Invasive species often possess the ability to respond rapidly to change and they often exist alongside humans. Wild hogs (Sus scrofa) are perhaps one of the most infamous examples of an invasive species. The spread of wild hogs necessitates effective communication with the public being impacted by them, as well as a continuation of research to learn more about wild hog behavior to promote effective management. Chapter 1 focuses on how we created a website …

Influence Of Hygrothermal Conditions Of The Bistability Of Asymmetric Carbon Fiber Laminate Composites, Celia Hill

All Theses

Carbon fiber-reinforced polymer (CFRP) laminates have widespread use in many industries because of their exceptional strength-to-weight ratio. Carbon fiber laminates following an asymmetric layup orientation can exhibit bistability meaning the laminate can exist at two stable geometric configurations. The morphing characteristics of bistable CRFP has a growing level of interest because of its potential in various applications including space aircraft structures for easy repair, automotive structures for energy dissipation and ergonomics, robotics for flexible motion and energy harvesting. Existing research shows that both moisture and temperature affect the material properties and behavior of CFRP laminates, however, the influence of moisture …
