Guide To Nebraska's Wetlands And Their Conservation Needs, Third Edition, 2022, Ted Lagrange

Nebraska Game and Parks Commission: Publications

Wetlands: a source of great interest, and at times conflict. Wetlands represent different things to different people. To some people they may be considered shallow, muddy nuisances whereas to others they are considered to be wonderful, varied, and productive assets. This is because wetlands take on many roles as part of an elaborate and dynamic system. Understanding wetlands requires understanding the complex and varying roles they can play. To aid in this understanding, this guide defines wetlands, discusses their importance and dynamics, identifies threats and losses, describes conservation programs, and takes an in-depth look at Nebraska’s regional wetland complexes.

¿Aviso O Alerta? Developing Effective, Inclusive, And Consistent Watch And Warning Translations For U.S. Spanish Speakers, Joseph E. Trujillo-Falcón, América R. Gaviria Pabón, Joseph T. Ripberger, Abby Bitterman, Jonathan B. Thornton, Mackenzie J. Krocak, Sean R. Ernst, Estilita Cassiani Obeso, John Lipski

National Oceanographic and Atmospheric Administration: Technical Reports and Related Materials

Spanish-speaking populations in the United States are more vulnerable in disaster contexts due to inequities, such as language barriers, that prevent them from receiving life-saving information. For the past couple of decades, governmental organizations have addressed these issues by translating weather watches, warnings, and advisories into Spanish. Previous studies suggest that these Spanish translations do not communicate the same level of urgency as their English counterparts. To identify whether these translated products result in inequities between English and Spanish speaker reception and comprehension of forecast information, we asked a representative sample of U.S. English (n = 1,550) and Spanish (n …

Dissecting The Cellular Landscape And Transcriptome Network In Viral Myocarditis By Single-Cell Rna Sequencing, Ninaad Lasrado, Nicholas Borcherding, Rajkumar Arumugam, Timothy K. Starr, Jay Reddy

School of Veterinary and Biomedical Sciences: Faculty Publications

Coxsackievirus B3 (CVB3)-induced myocarditis is commonly employed to study viral pathogenesis in mice.Chronically affected micemaydevelop dilated cardiomyopathy, which may involve the mediation of immune and nonimmune cells. To dissect this complexity, we performed single-cell RNA sequencing on heart cells from healthy and myocarditic mice, leading us to note significant proportions of myeloid cells, T cells, and fibroblasts. Although the transcriptomes of myeloid cells were mainly of M2 phenotype, the Th17 cells, CTLs, and Treg cells had signatures critical for cytotoxic functions. Fibroblasts were heterogeneous expressing genes important in fibrosis and regulation of inflammation and immune responses. The intercellular communication networks …

An Overview Of Integrated Pest Management In Greenhouse Systems, Kateri Cavanagh

Department of Entomology: Distance Master of Science Projects

Greenhouses are technological advancements that have existed since the first century. Human life and the field of agriculture have greatly improved with their invention. However, greenhouses come with their own set of challenges. One of the biggest issues with greenhouse systems is the presence of large pest populations. This is due to the ample food and water supply along with the relative stability of greenhouses. Pests in greenhouses are usually dealt with through the application of chemical pesticides. However, integrated pest management (IPM) is gaining traction for use in greenhouse systems. This overview will cover the history of greenhouses and …

A Review Of The Repellency Properties Of Pyrethrins, Gary Frazier

Department of Entomology: Distance Master of Science Projects

Pyrethrum is an insecticide created from the dried flower heads of plants in the genus Chrysanthemum. The six compounds responsible for the insecticidal activity are collectively known as pyrethrins, and are known individually as Pyrethrin-I, Pyrethrin-II, Cinerin-I, Cinerin-II, Jasmolin-I, and Jasmolin-II. Of these compounds, Pyrethrin-I is best known for mortality, and Pyrethrin-II is best known for knockdown activity (Sisay et al. 2001). These compounds are voltage gated sodium-ion channel disruptors acting on nerve cells. The inside of nerve cells is negative relative to the outside at rest. It is due to an imbalance between ions on either side of the …

“It Was Just My Name!”: A Crt/Crf Analysis Of International Female Graduate Students’ Perception And Experiences Regarding Their Ethnic Name, Peiwen Wang, Xiaoyan Gu, Amanda R. Morales

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Although international female students accounted for 44% of the enrolled international students in the United States (U.S. Department of Homeland Security’s Student and Exchange Visitor Information System, 2020), their experiences regarding their ethnic name are relatively understudied in onomastic literature. This study considers the experiences of eight international female graduate students of Color who are studying at a Midwestern predominantly White university. Utilizing Critical Race Theory (CRT) and Critical Race Feminism (CRF) as the theoretical and analytical lenses, this qualitative phenomenological study collected data through semi-structured, in-depth interviews. We explore the meaning of ethnic names and their connection to participants’ …

Friends-Based Protective Strategies And Unwanted Sexual Experiences: A Daily Diary Examination Of First Year College Women, Jessica A. Blayney, Tiffany Jenzer, Anna E. Jaffe, Quinn Carroll, Jennifer P. Read

Department of Psychology: Faculty Publications

Risk for unwanted sexual experiences can emerge in social contexts—the same contexts that early college women navigate with their friends. Though friends naturally engage in prevention strategies, less is known about how capable guardianship influences risk. Using multilevel structural equation modeling, the present study examined guardianship at the person and situation levels. First-year college women (N = 132) completed eight weekends of daily surveys. We examined whether guardianship (e.g., more friends present, greater proportion of female friends, no intoxicated friends) would reduce unwanted sexual experience risk and if this relation was mediated by friends-based strategy use. An alternative model …

Psychological And Physical Intimate Partner Aggression Are Associated With Broad And Specific Internalizing Symptoms During Pregnancy, Gabriela R. Perez, Sara M. Stasik-O’Brien, Lauren M. Laifer, Rebecca L. Brock

Department of Psychology: Faculty Publications

Background: Intimate partner violence (IPV) has serious consequences, particularly during high-risk periods such as pregnancy, which poses a significant risk to maternal mental health. However, it is unclear whether IPV presents a broad risk for psychopathology or is specific to distinct diagnoses or symptom dimensions (e.g., panic, social anxiety). Further, the relative impact of physical versus psychological aggression remains unclear. Methods: One hundred and fifty-nine pregnant couples completed surveys assessing psychological and physical intimate partner aggression unfolding in the couple relationship, as well as a range of internalizing symptoms. Results: Psychological and physical aggression were each associated with broad negative …

Peer Coach Support In Internet-Based Cognitive Behavioral Therapy For College Students With Social Anxiety Disorder: Efficacy And Acceptability, Chandra L. Bautista, Allura L. Ralston, Rebecca L. Brock, Debra A. Hope

Department of Psychology: Faculty Publications

Social anxiety disorder is common among emerging adults and is associated with serious functional impairment. Cognitive-behavioral therapy (CBT) is an effective intervention for social anxiety. An online version may increase access but low completion rates limit utility. This study investigated a self-guided, internet based CBT (ICBT) with peer coach support. Participants were 35 undergraduate students randomized for immediate treatment (IT) or wait-list control (WL) in a randomized controlled trial design. IT participants completed a six-week ICBT program on their own and met briefly with a minimally trained undergraduate student as a “coach” between each lesson. IT participants had a greater …

Attachment Anxiety And Avoidance Predict Postnatal Partner Support Through Impaired Affective Communication, Frances C. Calkins, Rebecca L. Brock

Department of Psychology: Faculty Publications

Objective: The purpose of the present study was to investigate perceived difficulties in affective communication as a key mechanism linking attachment anxiety and avoidance during pregnancy to the quality of postpartum support received by partners.

Background: During the postpartum period, partner support has the potential to promote family well-being by mitigating stress related to changes experienced during this transition. Attachment security is one of the most robust predictors of intimate relationship processes and impacts partner communication and support dynamics.

Method: Heterosexual couples (N = 159) completed surveys and semi-structured interviews to obtain measures of attachment security, perceived difficulties in …

Safety Splash: Pool Safety For Children And Adults, Rachel Lofton

Honors Program: Senior Projects (Public)

This outreach project was made to address the issue of too many children drowning at pools due to a lack of water safety education. The dissemination of pool safety education is imperative to reduce accidental injuries and drownings. The goal of the Safety Splash video and supplemental materials is to provide pool safety education for children and adults. By encouraging conversations between children and adults before going to the pool, there can be an intervention that reduces the risk of injury and drowning once they arrive. Through research, I compiled information to support the effectiveness of a combination video, pamphlet, …

The Relation Between Childhood Maltreatment And Marriage Quality In Adulthood, Melanie Wagner

Honors Program: Senior Projects (Public)

Childhood maltreatment poses the potential for lasting effects on survivors as they enter adulthood. Research lacks investigations into these potential effects, such as the impact on interpersonal relations. This study investigates the correlation between different types of childhood maltreatment and overall quality of marriage, as well as aims to identify which type of childhood maltreatment may be the strongest relative predictor of marital quality. Analyses on a newlywed dataset from Lancaster County, NE yielded results of a strong negative association between measures of childhood maltreatment and marital quality through the application of the Childhood Trauma Questionnaire and the Quality of …

The Intersection Of Leadership Identity Development And Meaning-Making Experiences In College Students, Tori Pedersen

Honors Program: Senior Projects (Public)

The current study explored the intersection of meaning-making with leadership identity development through a narrative lens. Phenomenological interviews were conducted with six senior college students who participate in a leadership mentoring program. Results showed there are six themes of meaning-making experiences that influence leadership identity development: : (a) Confidence, (b) Growth From Challenges, (c) Identity, (d) Influence by Others, (e) Influencing Others, and (f) Involvements. These findings encourage the practice of developing leadership development curricula based upon these themes to further develop leadership identity in students.

Opposing Effects Of Myzus Persicae-Induced Lipase 1 And Jasmonic Acid Influence The Outcome Of Arabidopsis Thaliana–Fusarium Graminearum Interaction, Syeda T. Alam, Sujon Sarowar, Hossain A. Mondal, Ragiba Makandar, Zulkarnain Chowdhury, Joe Louis, Jyoti Shah

Department of Entomology: Faculty Publications

Fusarium graminearum (Fg) is an important fungal pathogen of small grain cereals that can also infect Arabidopsis thaliana. In Arabidopsis, jasmonic acid (JA) signalling involving JASMONATE RESISTANT 1 (JAR1), which synthesizes JA-isoleucine, a signalling form of JA, promotes susceptibility to Fg. Here we show that Arabidopsis MYZUS PERSICAE-INDUCED LIPASE 1 (MPL1), via its influence on limiting JA accumulation, restricts Fg infection. MPL1 expression was up-regulated in response to Fg infection, and MPL1-OE plants, which overexpress MPL1, exhibited enhanced resistance against Fg. In comparison, disease severity was higher on the mpl1 mutant than the wild type. JA content was …

Exploring 3d Data Reuse And Repurposing Through Procedural Modeling, Rachel Opitz, Heather Richards-Rissetto, Karin Dalziel, Jessica Dussault, Greg Tunink

Department of Anthropology: Faculty Publications

Most contemporary 3D data used in archaeological research and heritage management have been created through ‘reality capture,’ the recording of the physical features of extant archaeological objects, structures, and landscapes using technologies such as laser scanning and photogrammetry (Garstki 2020, ch.2; Magnani et al. 2020). A smaller quantity of data are generated by Computer Aided Design (CAD) and Building Information Modeling (BIM) projects, and even fewer data are generated through procedural modeling, the rapid prototyping of multi-component threedimensional (3D) models from a set of rules (Figure 8.1.). It is unsurprising therefore that in archaeology and heritage, efforts around digital 3D …

Challenges And Enabling Features Of Small And Medium Infrastructure Public-Private Partnerships (P3s): A Case Study Of The Us P3 Infrastructure Market, Yunping Liang, Baabak Ashuri

Durham School of Architectural Engineering and Construction: Faculty Publications

Purpose: In classical perspective, projects under a certain size are not feasible for P3. However, there is an emerging trend on using P3 to deliver projects that are frequently small to medium sized to meet ever-increasingly complex social needs, including enhancing lifecycle performance of existing facilities, designing and building for resilience and sustainability, ensuring cost effectiveness of public spending, and fostering innovation. In contrast with the increasing implementation, small and medium P3s, especially those in the United States, receive little attention in existing studies. This study aims at answering the question: in the context of the US, what features of …

Pandemic, Politics, And Public Opinion About Crime, Lisa Kort-Butler

Department of Sociology: Faculty Publications

Prior scholarship links ontological insecurities, racial tensions, and health issues to public opinion about crime. This project examined these forces in the context of the 2020 pandemic, racial justice demonstrations, and politics using data from the Nebraska 2020 survey (N=2775). Pandemicrelated insecurities and racial animus were associated with avoiding places in the community, worry about crime, and the belief that police in one’s community are underfunded. Trusting politicians but distrusting health leaders, and viewing COVID as an economic threat but not a health threat were associated with the belief police are underfunded. Results suggest that the politicization of the pandemic …

Ecological Intensification With Soil Health Practices Demonstrates Positive Impacts On Multiple Soil Properties: A Large-Scale Farmer-Led Experiment, Fernanda Souza Krupek, Daren D. Redfearn, Kent M. Eskridge, Andrea Basche

Department of Agronomy and Horticulture: Faculty Publications

Improving soil health is critical to reversing trends of soil degradation and is of increasing interest to a range of stakeholders including policymakers, agricultural industry leaders, food companies, and farmers. Crop and soil management practices focused on ecological functions can be effective in restoring fundamental biological, chemical and physical soil properties. The call for ecological intensification of agricultural systems has the potential to improve soil health and input-use efficiency. In this study, we developed a framework to classify spatial and temporal ecological intensification with soil health practices: tillage, crop rotation, cover crop, organic amendment, and crop-livestock integration. We applied this …

Essays On Conservation Outcomes On Rented Farmland: Role Of Gender, Diya Ganguly

Department of Agricultural Economics: Dissertations, Theses, and Student Research

The essays in this dissertation explore why female landowners may be less likely than male landowners to achieve long term conservation on their land. In Chapter 1 we develop theory to model the strategic interaction between a landowner and a tenant with a focus on their gender and implementation of conservation practices on land. Within the context of a sequential-move game, we use the principal-agent framework and identity theory to model land-use choice and equilibrium payoffs between landowner and tenant. We consider cash rent lease and discounted lease whereby the tenant pays a reduced rent if they implement conservation practices …

Sensors capable of measuring this quantity have been around for decades, however, the increasing focus in nano and microscale applications in the industry and academia demands more accurate and smaller devices. This paper reviews some of the methods used to develop heat flux meters targeted to nano and microscale, as well as some calibration processes for the same. A combination of Luminescence and non-luminescence methods for direct and indirect measurement of heat flux will be discussed. A glimpse of what the future …

Presidential Rhetoric In Times Of Health Crises: From President Eisenhower To President Trump, Abbi Murphy, Justin Kirk

Honors Program: Senior Projects (Public)

Three major health crises in American history include the polio epidemic in the 1950s, the Ebola crisis in 2014, and the coronavirus in 2020. Each of these viruses evolved under a different President, from President Eisenhower to President Obama to President Trump. Each of these presidents spoke to the people on their respective crisis, and here I examine speeches, addresses, and social media posts in order to examine the rhetorical strategies that each President utilized. Each of them had a similar goal in mind, to eradicate the disease and quell the public’s fears. However, they all had advantages and disadvantages …

A Meta-Analysis Examining Technology-Assisted L2 Vocabulary Learning, Aiqing Yu, Guy Trainin

Department of Teaching, Learning, and Teacher Education: Faculty Publications

This meta-analysis examines the effectiveness of technology-assisted second language (L2) vocabulary learning as well as identifies factors that may play a role in their effectiveness. We found 34 studies with 2,511 participants yielding 49 separate effect sizes. Following the procedure developed by Hunter and Schmidt (2004), we corrected for sample size bias and measurement error. The overall effect size for using technology to learn L2 vocabulary was d = 0.64, which is a moderate effect size. The Q statistic indicated a significant variability in effect size, so we followed up with a theory-driven moderator analysis. The results of the moderator …
