Inactivation Of E. Faecium Nrrl B-2354 In Whole Black Pepper By Fluidization With Hydrogen Peroxide Vapor, Daniela Segura

Department of Food Science and Technology: Master of Science with Project Option

This study evaluated Enterococcus faecium NRRL B-2354 as a surrogate for Salmonella inactivation in black peppercorns treated with hydrogen peroxide (HP) vapor via fluidization. The selected parameter for dwell temperature was 60ºC for 60 minutes. The reduction of both Salmonella and E. faecium, along with changes in water activity, color, and residual hydrogen peroxide, were measured before, immediately after treatment and at 24 and 48 hours post-treatment. Results showed that E. faecium exhibited a significantly greater reduction (4.63 ± 0.55 log CFU/g) compared to Salmonella (2.94 ± 0.16 log CFU/g) (p < 0.05), making E. faecium unsuitable as …

Enhancing Faculty Preparedness To Teach Students With Learning Disabilities: A Community College Insight, Mayda Gonzalez

Instructional Leadership Abstracts

Conclusion

As more students with learning disabilities enroll in college, faculty preparedness and the support institutions provide have become increasingly important. Despite some progress, a graduation gap still exists, highlighting the need for meaningful change. This study emphasizes that welltrained faculty are essential for creating inclusive classrooms. Educators can establish environments where all students can thrive by utilizing Universal Design for Learning (UDL), adaptable teaching methods, and fostering positive attitudes.

To help close this gap, institutions must invest in ongoing, research-based professional development. Mandatory training will equip faculty with the tools to support neurodiverse students effectively. By implementing these changes, …

Cotopaxi: Stewardship To Succession, Roy Dumblauskas, Landry Geiger, John Post, Jack Smiley, Zachary Wallenburg

B-Corp Case Studies by UNL Raikes Seniors

Cotopaxi is a company built from the ground up to be socially conscious, from their governance structure to their deeply ingrained core values. Despite being in a market dominated by incumbents like Patagonia, they've done well in the past, bringing in around $160 million in revenue in 2023 while donating millions outright and carefully maintaining ethical internal business practices. But just as the company began taking off, founder Davis Smith left the company to pursue religious mission work. He spent years, starting the search in 2019 before finally stepping down in July 2022, looking for a successor, eventually finding a …

B-Corp Case Studies by UNL Raikes Seniors

Bombas is a leading premium basics brand with a unique focus on socks and philanthropy. Its 'buy one, give one' model, along with a viral appearance on Shark Tank, helped propel the company into the public eye. Since the company’s inception, they have donated over 150 million essential clothing items to people in need. Bombas’s commitment to quality and product innovation has earned it a loyal consumer base. However, its production practices and business model have faced scrutiny, raising questions about whether the company is truly maximizing its impact in giving back

Artificial Interiors, Alex Renbarger

School of Art, Art History, and Design: Theses and Student Creative Work

Artificial Interiors is a series of intimately scaled paintings that depict dramatically lit domestic interiors. My limited yet saturated color palette creates a dark atmosphere that feels both strange and familiar, contributing to the unsettling ambiance of the domestic scenes. Their origins in Artificial Intelligence (AI) prompts further reinforce this effect. Each painting begins as a composite collage created with AI-generated images, iterative prompts, and Photoshop, in a process that creates fantasy spaces, detached from real ones, even as their elements - sofas, chairs, corners, stairs - suggest common expectations and experiences for domestic life in the U.S.

Commonly Encountered Insect Pests Of Virginia, Angel Almaas

Department of Entomology: Distance Master of Science Projects

Foreword

The goal of this pamphlet is to provide an outline of over 50 commonly encountered pest species that occur in Virginia. Care was given to represent each category of pest. This is by no means an exhaustive list of insect pests in Virginia. However, the profiles chosen are reflective of data from insect inventories performed on military bases in coastal Virginia (Fort Eustis, Langley Air Force Base, and Camp Pendleton), sampling from counties in central Virginia, insect species diversity surveys performed in northern Virginia, annual species counts of vector surveillance data from the Virginia Department of Health, and information …

A Comprehensive Catalog Of The Important Insects Found Within The Usa's National Parks, Raven Patrick

Department of Entomology: Distance Master of Science Projects

To fulfill the Masters in Entomology Masters Project requirement, I chose to focus on creating a list of the important insects found within the National Parks of the United States. Important insects, although subjective, was grouped into four categories for my project: Keystone Insect Species, Invasive Insect Species, Insect Species of Conservation Concern, and Culturally Significant Insect Species. Keystone insects include those that are important parts of ecosystems and who which without would cause a significant upset to the food web. Invasive insect species includes those that are introduced into parks accidentally, usually through anthropogenic means, and are causing ecological …

Algorithms For Order Statistics In Farey Sequences: A Computational Study, Connor Weyers

School of Computing: Dissertations, Theses, and Student Research

Farey sequences are the sets of irreducible fractions in increasing order with denominator less or equal to some integer n. They are a well-known concept in number theory problems and are related to many other concepts in number theory including integer factoring, Fibonacci sequences, and Riemann’s Zeta function. In this paper, we investigate some known algorithms to solve certain problems in Farey sequences from a computational perspective. In particular, we implement established algorithms that have not been previously implemented with the goal of creating a package that can be used more broadly. We also develop a new algorithm for rational …

Tillamook: Ethical Values Or Misleading Marketing?, Victoria Chin, Ealynn Hsu, Kyana Le, B Littman, Natalia Trejo Andalon

B-Corp Case Studies by UNL Raikes Seniors

Tillamook began as a humble cooperative for the local dairy farmers of Tillamook County, Oregon, to ensure that high-quality cheese was the local standard. As time passed, Tillamook evolved to establish an internal Farm Services Team to help support each farmer and pay above market value for members’ milk–in return, receiving a stable supply of dairy to manufacture its dairy-based products. Additionally, the farmers are still the ones who call the important shots for Tillamook rather than other corporate shareholders. Tillamook County Creamery Association (TCCA) has since expanded nationally, but the foundation remains the same: high-quality dairy to create high-quality …

Shakespeare’S Early Histories And The Construction Of Government, Paul Olson

Department of English: Faculty Publications

Shakespeare’s first tetralogy has been treated as an account of the reinvention of government, especially a Hobbesian reinvention demonstrating how authoritarian government forces order out of chaos. This article argues that, though Hobbesian elements present themselves, Shakespeare employs subtexts available to his time and place to speak of how orderly government is constituted: that is, he relies on accounts of the Fall from perfection into chaos and the return from it through divinely blessed kingship that are present in syncretic readings of Ovid and the Bible. The two subtexts give order to the progress from Fall into chaos and back …

Clinical Case Study: The Effects Of Saltatory Pneumotactile Stimulation Of Glabrous Hand And Perioral Face On Cerebral Oxygenation, Cognitive Performance, And Sensorimotor Function In An Adult Following Left Hemorrhagic Stroke, Tara L. Hull

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Stroke remains a leading cause of adult disability and a significant global health concern. Effective rehabilitation strategies for cognitive and communicative impairments following stroke are limited (Kuhn & Sharman, 2023). One emerging approach involves repetitive somatosensory stimulation to drive cerebral hemodynamic changes, potentially offering a novel rehabilitative method. Functional Near-Infrared Spectroscopy (fNIRS) is a non-invasive, accessible tool for monitoring these changes during stroke recovery. Prior studies suggest tactile stimulation rapidly affects brain hemodynamics (Custead et al., 2015; Oh et al., 2017). This clinical single-case study explored the use of GALILEO saltatory pneumotactile stimulation applied to the face and hand in …

Controlling The Narrative: How The United Daughters Of The Confederacy Shaped Collective Memory Through Romance Novels, Karie L. Cobb

Department of English: Dissertations, Theses, and Student Research

While existing scholarship on the United Daughters of the Confederacy (UDC) reveals the immense influence the organization wielded in the nineteenth and twentieth centuries, I assert that their legacy has had a broader and more insidious reach than previously believed. Through close analysis of two foundational romance novelists’ works published during the rapid escalation of the genre’s popularity, I contend that the rhetoric of the UDC shaped generations of Southerners as demonstrated through repetitions and parallels of the Lost Cause ideology found in UDC publications and sponsored materials within romance novels written by white Southern women who came of age …

Impact Of Diet Quality And Functional Food (Honey) On Gut Microbiota And Metabolic Health In Obesity, Sarah M. Eaton

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

Understanding the impact of dietary patterns and functional foods on human health is crucial for the advancement of evidence-based nutrition choices. This dissertation investigates the effects of three a priori-defined healthful dietary patterns as well as a functional food, specifically Manuka honey, on gut health and metabolic markers in individuals with overweight and obesity. Two studies were conducted to explore these relationships. The first study, a post-hoc, cross-sectional analysis, compared the effects of three healthful dietary patterns: Healthy Eating Index-2010 (HEI-2010), Dietary Approaches to Stop Hypertension (DASH), and Mediterranean Dietary Pattern (MDP) on markers of intestinal permeability and gut microbiota …

The Reality Of Transformation: A Case Study Of An American Community College Implementing Holistic Student Supports, Calie Marie Holden

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

This dissertation examines the implementation of Holistic Student Supports at a community college that served as an early adopter of this approach, providing insights into the decade-long process of transformational change. Against the backdrop of community colleges' ongoing efforts to improve completion rates, this study investigates how one institution navigated the implementation process, made necessary adaptations, and sustained reform efforts over time. Through document analysis, semi-structured interviews, and a focus group, this study documents the evolution of this initiative from its inception in 2010. Kotter's Eight-Step Change Model frames the analysis, which confirms the model's applicability and extends it by …

Transgender And Gender Diverse Young Adults’ Navigation Of Sexuality: What Mental Health Providers Need To Know, Sage A. Volk

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

Though literature has documented that TGD individuals may face unique challenges when attempting to develop healthy romantic and sexual relationships (Hill-Meyer & Scarborough, 2014), research has also identified that intimate partners can serve as an immeasurable source of support and resilience for their TGD partners (Coppola et al., 2021; Galupo et al., 2019). While there is strong evidence to support the importance of TGD individuals developing healthy intimate relationships, there is little guidance in the literature for mental health providers wanting to discuss these domains with TGD clients in psychotherapy (Spencer and Vencill, 2017).

The present study addresses this gap …

Transgender And Gender Diverse Youth Navigating Relationships And Sexuality: Recommendations For Affirming Clinical Practice, Hannah Marie Coffey

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

Healthy relationship development is critical for adolescents’ social-emotional wellbeing, and shifting social expectations and identity development in adolescence can be challenging (Kenny et al., 2013; Roach, 2018). This can be particularly complex for transgender and gender diverse (TGD) youth given the occurrence of identity development alongside navigating safety, access to affirming spaces, and limited availability of queer-inclusive education (Levitt and Ippolito, 2014; Xing et al., 2015). The positive psychosocial impacts of comprehensive sex education and the relevance of discussing relationships in therapy with adolescents situate mental health providers well to address some of the gaps in knowledge and access to …

An American Song Cycle: A Performance Guide To The Rim Of Love By Andrea Clearfield, Margot Marie Porter

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

Philadelphia-based American female composer Andrea Clearfield (b. 1960) arranged the cantata The Rim of Love into a song cycle for soprano and piano, featuring poetry written by Manfred Fischbeck (1940–2021). Fischbeck and Clearfield met in 1985 while both on faculty at the University of the Arts in Philadelphia, where they cultivated a lifelong creative partnership and friendship, along with being romantic partners for 20 years.

Clearfield has composed over 170 works, including opera, chamber ensembles, solo instruments, chorus, and orchestra. In 2005, the nonprofit mentoring program Astral Artists, based out of Philadelphia, commissioned Clearfield to compose The Rim of Love …

Holding Ground In The Cerulean Tide: Minority Party Legislators' Strategies For Advancing Climate Policies In Landslide States, Sukjae Lee

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

This dissertation addresses a key puzzle: Why do states sometimes adopt nationally polarized policies, such as climate change legislation, even when doing so does not align with strict partisan interests? The analysis focuses on “landslide states,” where a single party overwhelmingly dominates, and the minority party cannot realistically expect to gain a majority. In these environments, reduced partisan conflict allows minority party legislators to break from traditional partisan paths. As a result, I argue that electoral motivations drive them to signal moderation by advancing liberal policy agendas or incorporating provisions that minimize backlash from their core constituents in landslide states. …

How Do School-Level Dynamics Impact Mainstreaming Practices In American Schools?, Natalie M. Watson

Department of Sociology: Dissertations, Theses, and Student Research

How do school-level dynamics impact the everyday experiences of students with disabilities, compared to their abled peers? Extant research has mostly focused on the experiences of individual students with disabilities, and their teachers. We know far less about how school-level dynamics shape students’ experiences. Historically, American schools formally separated students with and without disabilities, though the specific mode varied over time -- ranging from explicit institutionalization to segregation in special education programs. At least since the passage of the Americans with Disabilities Act in 1990, efforts to educate students with disabilities alongside their abled peers in mainstreamed settings have increased …

Giving Voice To Student Grief: Using Community-Based Participatory Research To Develop And Pilot A Translational Storytelling Intervention For Bereaved College Students, Cassidy Rae Taladay-Carter

Department of Communication Studies: Dissertations, Theses, and Student Research

The purpose of this dissertation was to employ community-based participatory research (CBPR, Wallerstein et al., 2018) methods to attend to a pressing issue in the community. In partnership with one local grief center, we identified the need for enhanced grief support for current emerging adult undergraduate students in our area. Nearly 50% of U.S. emerging adults enrolled in four-year residential universities experience the death of an important figure (Cox et al., 2015; Cupit et al., 2021), at a time when they are developing important facets of their narrative identity. Without the coherence and meaning structures provided by narrative identity, students …

The Impact Of Provider Communication On Treatment Adherence In Patients With Hypertension And Diabetes, Trey Carlson

Honors Program: Senior Projects (Public)

Current research cites effective provider communication as an important factor in improving treatment adherence and the health outcomes of patients. This study examines the effect of provider communication on treatment adherence in patients with chronic illnesses with a specific focus on hypertension and diabetes. Provider communication was measured using patient satisfaction surveys and treatment compliance was measured as the percentage of hypertensive and diabetic patients with a blood pressure below 140/90 mmHg and hemoglobin A1C levels below 9%. A one-way MANOVA revealed that provider communication had no significant impact on the combined treatment compliance variables for hypertension and diabetes (Wilk’s …

Dental Disparities: An Analysis Of Dental Caries Risk Factors Promoting Disparities Between Rural And Urban Communities In Nebraska, Nick Lounsbery

Honors Program: Senior Projects (Public)

The prevalence of dental caries in the United States remains a public health concern, as it is one of the most common chronic conditions across people of all ages. Research shows that preventative measures including brushing, fluoridated water, and regular checkups are effective strategies to mitigate tooth decay. However, there appears to be a divide between rural and urban populations, as the presence of dental cavities is significantly greater in remote areas in the State of Nebraska. Research methods used in this analysis included analyzing accredited academic literature to illustrate how cavities form from a biochemical perspective. Research methods also …

Enhancing Remote Sensing Imagery Temporal Resolution Using Starfm Data Fusion Approach For Improved Land Surface Monitoring, Ahmadreza Pourghodrat

School of Computing: Dissertations, Theses, and Student Research

High-resolution remote sensing imagery plays a critical role in various domains, such as farm-level agricultural operations, environmental monitoring, and natural resource management. However, data with high spatial resolution typically have low temporal resolution, and those with high temporal resolution often lack spatial detail. For example, Landsat 8 and 9 satellites deliver high spatial resolution images with a 30-meter pixel size but suffer from low temporal resolution, with a 16-day revisit cycle. In contrast, satellites like MODIS and VIIRS provide daily images but with a much coarser spatial resolution (375 meters or more), reducing spatial details. Additionally, there is a lack …
