Application Of Cementitious Materials And Fiber Reinforcement To Enhance Lime Stabilization For Nebraska Shale Soils, Jongwan Eun, Seunghee Kim, Chung R. Song, Laith Ibdah, Kenaz Owusu

Nebraska Department of Transportation: Research Reports

Lime stabilization is a widely used technique to improve weak subgrades; however, its effectiveness under freeze-thaw cycles remains a critical challenge. This study investigates the incorporation of cementitious materials and fiber to enhance the mechanical properties and environmental resistance of lime-stabilized soils under such conditions. Two types of soil, gray shale (plasticity index of 37.8) and clay soil (plasticity index of 19.0) from Nebraska, were used. Stabilization mixtures included lime dosages of 0%, 3%, and 6% by weight, combined with either 10% fly ash or 3% and 6% cement by weight, and 0% and 1% fiber. The experimental program comprised …

Racial Powers, Talhah Mustafa

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This dissertation will be divided into three papers that in some way considers the concept of racial powers. The concept of racial power is under-researched and presupposed in the Philosophy of Race literature. Many arguments in this field seem premature without a general understanding of racial powers. The first paper fills that gap by introducing and defending the view that racial powers are possessed in virtue of one’s race or perceived race.

In the second paper, I consider Chike Jeffers’ cultural constructionist account of race. The nature of race is complex, requiring nuanced consideration. Chike Jeffers’ cultural constructionist may seem …

The Effect Of Voir Dire Variations On Juror Disclosures, Joshua A. Haby

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Voir dire, sometimes referred to as jury selection, is the legal process the court uses to pursue an impartial jury. The presiding judge controls many aspects of how voir dire proceeds. In deciding voir dire variations, the judge presumably engages in a calculus weighing factors like the goal of voir dire, time, and specific trial needs to determine appropriate procedures. Certain procedures are considered expansive and others limited. Where expansive procedures provide more information from jurors, they may take longer; limited procedures may be more expeditious but limit access to information from jurors (Hans and Jehle, 2003; Mize, Hannaford-Agor, and …

Empowering Multilingual Learners Through Culturally Sustaining Pedagogy And Arts-Based Learning In Burkina Faso, Inoussa Malgoubri

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This dissertation explores how culturally sustaining pedagogy and arts-based learning can engage multilingual learners of English as an Additional Language (EAL) in Burkina Faso. The research emphasizes the incorporation of local cultural elements and learners' linguistic backgrounds into the EAL curriculum to address challenges such as limited classroom interactions (Somé-Guiebré, 2020) and monolingual instructional strategies with inadequate cultural representation (Ndlangamandla, 2024). This qualitative study integrates culturally relevant materials, including Forum Theater, slam poetry, and griot-style storytelling, to create an engaging and inclusive learning environment. Data consisted of observation, images from arts-based workshops and pre- and post-workshop interviews with selected teachers …

Exploring The Pathogen Profiles Of Ancient Feces, Drew Capone, David Holcomb, Amanda Lai, Karl Reinhard, Joe Brown

Karl Reinhard Publications

Analysis of ancient desiccated feces – termed paleofeces or coprolites – can unlock insights into the lives of ancient people. We collected desiccated feces from caves in the Rio Zape Valley in Mexico (725-920 CE). First, we extracted DNA with methods previously optimized for paleofeces. Then, we applied highly sensitive modern molecular tools (i.e., PCR pre-amplification followed by multi-parallel qPCR) to assess the presence of 30 enteric pathogens. We detected ≥1 pathogen associated gene in each of the ten samples and a mean of 3.9 pathogens per sample. The targets detected included Blastocystis spp. (n=7), atypical enteropathogenic E. coli (n=7), …

Effect Of Feeding Fenugreek Extract And Encapsulated Lecithin On Finishing Cattle Performance, Carcass Characteristics, And Liver Abscesses, Sofia Suarez Lorences, Rebecca L. Mcdermott, Joshua R. Benton, Robert Bondurant, Willard Lemaster, James C. Macdonald, Galen E. Erickson

Nebraska Beef Cattle Reports

Summary with Implications

A feedlot study was conducted to evaluate the effects of adding fenugreek extract and encapsulated lecithin (Furst-McNess Company, Rockford, Illinois, United States) on finishing cattle performance, carcass characteristics, and liver abscesses. Treatments were applied as a 2×2 factorial that included a control diet with no additive; a diet containing fenugreek extract; a diet containing encapsulated lecithin; and a diet containing both fenugreek extract and encapsulated lecithin. Tylosin was not included in any diets to test natural occurrence of liver abscesses. No interactions were observed between fenugreek extract and encapsulated lecithin treatments but neither feed additive impacted intakes, …

Effects Of Allocation Frequency On Cattle Performance And Forage Utilization When Swath Grazing A Sorghum-Sudangrass Hybrid In Eastern Nebraska, Thomas E. Aquino, Mary E. Drewnoski, Pedro Henrique J. Fernandes

Nebraska Beef Cattle Reports

Summary with Implications

A sorghum-sudangrass hybrid was swath grazed by growing steers (529 ± 18 lb) from November 2023 to January 2024. Treatments were offering new forage once (1X) or twice (2X) per week to determine the effect of allocation frequency on animal performance and forage utilization. Average daily gain was not impacted by treatment (1X = 0.45 ± 0.1 lb/day, 2X = 0.45 ± 0.1 lb/day). Pre-and post-graze biomass samples were collected to estimate forage utilization, which was not different between treatments (1X = 57.1 ± 3.6%, 2X = 61.1 ± 3.6%). However, there was a difference in carrying …

Chaucer’S Complaint To His Purse And Authority In The World, Paul A. Olson

Department of English: Faculty Publications

Chaucer’s Complaint to His Purse concerns more than the poet’s financial need under the new Lancastrian administration. It speaks to the limits of Henry IV’s royal authority and, through irony, to the limitations of Chaucer’s purse’s power. Underlining royal limits, Chaucer petitions the king as one who holds office through election and line but not con-quest, which is Henry’s position on his office as well. In speaking iron-ically of the purse’s authority, the poet addresses the gold that the mon-arch might grant him as if it constituted a human or divine patron, but he does so in a hierarchy of …

Research Report: Confidence In Institutions, Heather Akin, Cheryl A. Burkhart-Kriesel, Mary Emery, Katelyn Larson, Bradley D. Lubben, L. J. Mcelravy, Rebecca J. Vogt

Nebraska Rural Poll

This report details 943 responses to the 2025 Nebraska Rural Poll, the 30th annual effort to understand rural Nebraskans’ perceptions. Respondents were asked a series of questions about their confidence in institutions. Trends for some of the questions are examined by comparing data from the 2017 Poll and 2021 Poll to this year’s results. In addition, comparisons are made among different respondent subgroups, that is, comparisons by age, occupation, region, etc. Based on these analyses, some key findings emerged:

• Rural Nebraskans’ confidence in many institutions did not change much during the past eight years. However, more rural Nebraskans have a …

Research Report: Insights Into Community, Heather Akin, Cheryl A. Burkhart-Kriesel, Mary Emery, Katelyn Larson, Bradley Lubben, L. J. Mcelravy, Timothy Meyer, Rebecca J. Vogt

Nebraska Rural Poll

Rural Nebraskans are more positive about the current change in their communities this year but are less positive about its future. Starting three years ago, the proportion believing their community changed for the worse was more than the proportion believing it had changed for the better (similar to what occurred in 2003 and 2009). However, last year that trend reversed back to the typical pattern and continued this year. This year, more people believe their community has changed for the better than has changed for the worse. When asked about what they expect ten years from now, this year more …

The Nebraska Criminal Law Practitioner's Guide To Representing Non-Citizens In State Court Proceedings, 2025 Edition, Kevin Ruser

The Nebraska Criminal Law Practitioner's Guide to Representing Non-Citizens in State Court Proceedings

PREFACE TO THE 2025 EDITION

There have been a good deal of developments in this area since the 2023 revision to this Guide. Two are especially notable. The first is the 2024 decision by the United States Supreme Court in Loper Bright Enterprises v. Raimondo, in which the Court overruled its 1984 decision in Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc. Although the contours of Loper Bright are still playing out, it is clear that the level of deference given to agency interpretations of the law under Chevron is no longer appropriate. That obviously has significant implications …

A Critical Role For An Honors Community Of Practice, Rebecca C. Bott-Knutson, Scott O'Leary, Scott Breuninger, Karen D. Youmans, Jeff Chamberlain, Sheila Nowinski

National Collegiate Honors Council Monographs: Chapters

The Honors Community of Practice is a promising form of professional development in honors, where the wide variety of institutions, professional roles, and structures can present challenges to inclusive and relevant programming. The HCoP’s flexible and responsive format allows individuals in different contexts to connect, share resources, and learn from one another. The fluid nature of HCoP discussions, in which participants shift between mentor and mentee roles, highlights expertise in the community and encourages new voices to emerge. Of course, the advantages of Communities of Practice are not confined to honors. Their adaptability and simplicity make it effective programming in …
