The Effect Of Need For Closure, Gender Essentialism, And Contact On Transphobia, Jacob E. Vargas
The Effect Of Need For Closure, Gender Essentialism, And Contact On Transphobia, Jacob E. Vargas
College of Education and Human Sciences: Dissertations, Theses, and Student Research
Using a motivated social cognition framework, this study explores whether there is an indirect effect of need for closure on transphobia via gender essentialism and whether this relationship is moderated by transgender contact. Data were collected from an undergraduate sample of 405 cisgender participants (nmen = 159, nwomen = 246). A simple mediation and a moderated mediation were used to examine the hypothesized relationships, controlling for participant gender. Results reinforced the positive correlation between gender essentialism and transphobia and the negative correlation between transgender contact and transphobia. However, the mediation and moderation hypotheses were not supported. Need …

Examining Trauma And Substance Use Co-Morbidity In African Americans, Breanne Maray Sande Russell
Examining Trauma And Substance Use Co-Morbidity In African Americans, Breanne Maray Sande Russell
Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–
Childhood maltreatment (CM) is a profound public health crisis that significantly elevates the risk for substance use disorders (SUDs), including alcohol and opioid misuse. Adolescents exposed to CM are especially vulnerable, often turning to substances as maladaptive coping mechanisms during critical developmental periods. African American youth bear this disproportionate burden, yet research addressing their unique experiences remains strikingly limited. Furthermore, while the co-occurrence of trauma-related disorders and substance use is well documented, racial and ethnic minority groups continue to be underrepresented in this literature. Emotion regulation difficulties are increasingly recognized as a mechanism linking PTSD symptoms with substance use, yet …
Echo Chambers On The Left, Echo Chambers On The Right: How Socioideological Identity Emotion Shape Social Interaction Behavior On Social Media, Dean Carl Jackson
Echo Chambers On The Left, Echo Chambers On The Right: How Socioideological Identity Emotion Shape Social Interaction Behavior On Social Media, Dean Carl Jackson
Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–
This dissertation investigates how echo chambers emerge on social media by shifting the lens from aggregate patterns of information exposure to moment-by-moment, individual level interaction decisions between peers. I theorize that selective exposure online is not only about what content people consume or avoid, but also about selective social exposure—accepting, rejecting, or sharing with the sources of that content—guided by sociopolitical identity, ideological distance (ID), and discrete emotions. To test this, I employ two survey experiments using real tweets varying in ideological extremity and measure user’s likelihood to Block, Follow, Retweet, or reply, alongside self-reported emotional reactions and ID between …

Examination Of Cooperative Extension As A Bridging Organization To Enhance Cross-Boundary Collaborative Water Management, Mark E. Burbach, Stephanie M. Kennedy, Weston M. Eaton, Kathryn J. Brasier, Daran R. Rudnick, Walt Whitmer
School of Natural Resources: Faculty Publications
We explored stakeholders’ familiarity with, trust of, perceived competence of, and shared vision with Cooperative Extension on water-related issues in two states to determine the degree to which Extension is positioned to be an effective bridging organization. Results of surveys in Nebraska and Pennsylvania showed that, overall, neither agricultural producers nor non-farm households were very familiar with Extension. However, both stakeholder groups perceived Extension to be trustworthy, competent, and have similar goals on water-related issues. Extension should renew efforts to bolster its familiarity among these groups to enhance its effectiveness as a bridging organization.

Cycling is increasingly recognized for its wide range economic, environmental, and health benefits as a mobility option. However, disparities in the provision and the quality of bicycle infrastructure persists. Ensuring fair access and usage of these benefits for all presents a significant challenge. As a result, establishing effective methodologies to evaluate cycling equity is critically important. This paper synthesizes research on infrastructure asset management with a focus on equity considerations in bicycle infrastructure. A systematic review of 19 North American studies critically examines how existing research categorizes vulnerable populations and assesses fairness. The results reveal that most existing analyses focus …

Green Project Finance For Infrastructure And Building Construction: Instruments And Benchmarks, Yunping Liang
Green Project Finance For Infrastructure And Building Construction: Instruments And Benchmarks, Yunping Liang
Durham School of Architectural Engineering and Construction: Faculty Publications
It is counterintuitive that both the practice and research on green project finance for infrastructure and building construction are ascendant and still have limited precedents, considering that individually, the two parts (i.e., project finance and sustainability in the built environment) are both familiar to the communities. To narrow the gap and facilitate the financing of the built environment’s sustainable transformation, this study systematically reviews the common instruments for financing green infrastructure and building projects. Benchmarking questions distinguishing the profile of green project finance from common construction project finance are developed based on the literature review and then are used for …

Effect Of Forage Allocation On Steer Performance When Grazing Cereal Rye, Shelby L. Davies-Jenkins, Abigail M. Sartin, Daren D. Redfearn, Mary E. Drewnoski
Nebraska Beef Cattle Reports
Summary with Implications
Cereal rye is the most common cover crop planted today. With its good winter tolerance and rapid spring growth during a gap in perennial pasture productivity, it is an attractive forage source in early spring. Unfortunately, optimum stocking rates and how they are related to forage biomass availability are unknown. The study objective was to understand the effect of forage allowance on steer performance when rotationally grazing fall-planted cereal rye in spring. Stocking rate was negatively correlated with pounds of forage offered. Surprisingly, amount of forage offered related to average daily gain. Growing steers grazing cereal rye …

Strategies Affecting Performance And Profitability Of May-Born Steers, Dempster M. Christenson, Jacki A. Musgrave, Richard N. Funston
Nebraska Beef Cattle Reports
Summary with Implications
This study compared the performance and economic outcomes of differing backgrounding and feedlot systems in May-born yearling steers. We hypothesized reduced supplementation with adequate forage availability while backgrounding weaned steers will yield a similar carcass with greater profitability. It was hypothesized yearling steers backgrounded on pasture before finishing in feedlot would have a more valuable carcass that is more profitable than steers that enter the feedlot immediately. Weaned steer calves were backgrounded with ad libitum hay and 4 lb/d supplement in drylot or on pasture with 1 lb/d supplement. As yearlings, half of each backgrounding group immediately …

Nebraska Beef Cattle Reports
Summary with Implications
This study evaluated feeding wet or dry traditional distillers grains with wet and dry fractionated distillers (Solbran) fed at 40% of diet DM compared to a corn control diet on enteric methane emissions and performance. Compared to the control, there was no difference in carbon dioxide production, but there was an increase in methane production in the steers fed fractionated distillers compared to conventional distillers. Feeding steers traditional or fractionated distillers grains increased consumption, increased gain, but improved conversions only for steers fed WDGS, while steers fed the other distillers grains had worse or the same feed …

Business Model Evaluation Of Renewable Energy Community In Multi Unit Residential Building In Canada Net Metering, Considering The Regulatory Framework, Ownership And Organizational Structure, Zahra Keshavarz Moraveji, Yunping Liang, Ursula Eicker
Durham School of Architectural Engineering and Construction: Faculty Publications
Renewable Energy Community (REC) is an emerging concept that empowers local customers to generate decentralized renewable energy. Integrating RECs into the building industry presents a promising opportunity to support the transition toward net-zero cities. However, the viability of RECs depends on regional regulatory frameworks, permitted governance structures, and very importantly, business models. Compared to pioneering European countries, Canada lacks the regulatory support needed to fully enable REC. This paper proposes and evaluates various business models for potential REC implementations under Canada's existing regulatory constraints. The analyzed models focus on "behind-the-meter" electricity distribution, a multi-stakeholder type of REC, where generation occurs …

Department of Sociology: Faculty Publications
Population aging is accelerating across Africa yet remains underrepresented in research, policy, and public health planning. This review critically examines how social determinants shape aging experiences across the continent, focusing on health, care systems, and structural inequalities. While traditional African societies have historically valued older adults, modernization, migration, and economic hardship have eroded support systems, leaving many to face old age with limited resources. Older Africans, particularly women and rural residents, contend with lifelong disadvantages including low education, informal labor, poverty, and gendered caregiving roles that contribute to poor health and social vulnerability. Health systems remain poorly equipped to address …

Geometric Modeling, Reconstruction And Evaluation Of Maize Leaf Morphology In 3d, Zhaocheng Xiang
Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–
Maize is a vital crop for global food security, yet quantitative characterization of its three-dimensional (3D) morphology remains a major challenge due to the geometric complexity of curved leaf structures and occlusions during data collection. This work presents an integrated framework for the digital reconstruction, parametric modeling, and functional analysis of maize leaf morphology and canopy architecture, advancing the precision and interpretability of phenotyping and modeling in smart agriculture.
First, we propose a descriptive and parametric model that represents maize leaves through three fundamental components: midrib, cross-section, and blade contour. Each is described by geometric curves and controlled by biologically …
Assessing Reproductive Health In Zoo-Managed African Elephant Bulls (Loxodonta Africana), Kaitlyn Marie Campbell
Assessing Reproductive Health In Zoo-Managed African Elephant Bulls (Loxodonta Africana), Kaitlyn Marie Campbell
Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–
Populations of zoo-managed African elephant (Loxodonta Africana) exhibit substantial individual- and population-level variation in reproductive success, yet research has largely focused on females, leaving male fertility poorly understood. Subfertility in bulls, characterized by low libido and inconsistent semen quality, poses significant challenges to genetic management and long-term population sustainability. This study a) systematically evaluates semen quality, b) identifies physiological, behavioral, social, and environmental determinants of fertility, and c) advances ex situ conservation through the expansion of the African elephant sperm bank. Between January 2023 and July 2025, 209 semen collection events were conducted from 13 sexually mature bulls …
In-Season Nitrogen Mmanagement: Leveraging Data Visualization For Precision Agriculture, Chathurika Harshani Narayana
In-Season Nitrogen Mmanagement: Leveraging Data Visualization For Precision Agriculture, Chathurika Harshani Narayana
Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research
Effective nitrogen management is vital for sustainable agriculture, impacting both crop yield and environmental health. Traditional methods often use fixed application rates set before planting, which do not adapt to changing crop needs during the season. This can lead to over- or under-application, reducing efficiency and sustainability. While modern tools like sensors, satellites, and UAVs provide valuable real-time data on crop and field conditions, integrating and using this data to guide timely nitrogen decisions remains a major challenge. In-season nitrogen management offers a solution by allowing for dynamic adjustments to nitrogen applications, addressing crop needs as they arise. This approach …
