Exploring The Impact Of Student-Faculty Partnership Program At A Hispanic Serving Institution, Alyssa Guadalupe Cavazos, Lesley Chapa, Javier Cavazos-Vela

To Improve the Academy: A Journal of Educational Development

Guided by a strength-based framework and counter-storying lens, we use a qualitative case study approach (Cook-Sather, 2020; Cook-Sather and Motz-Storey, 2016; Lechuga-Peña and Lechuga, 2018) to explore students’ and instructors’ experiences with a students as learners and teachers (SaLT) partnership program at a Hispanic Serving Institution (HSI). This study includes five students and five faculty members who participated in the student-faculty partnership program. Data collection involved student partners’ self-assessment reflections and faculty members’ pre- and post-program reflections on their experiences. Several themes were identified following a phenomenological analysis of students’ and faculty partners’ self-reflections. Themes emerging from student participants included …

Meanings Of Community: Educational Developers Experience Care, Satisfying Contributions, And Belonging In A Collaboration Across Institutions, Thomas M. Colclough, William J. Howitz, Daniel Mann, Katherine Kearns, Darren S. Hoffmann

To Improve the Academy: A Journal of Educational Development

We share insights from a mixed methods study to describe the experience of educational developers participating in a community of practice (CoP). This CoP consisted of 19 leaders at eight institutions, serving collectively as facilitators of a hybrid, across-institutional, seven-week workshop series on course design for graduate students and postdoctoral scholars. From results of a survey examining the functional and sustaining features of the community, we illustrate that members experience the community aspect of our CoP primarily as a sense of satisfaction/personal fulfillment and, to an extent, in the effectiveness/productiveness of collaborations between members. Members of our CoP experience several …

Writing Communities To (Re-)Engage Faculty: The U See I Write Initiative, Ilona S. Yim, Nina Bandelj, Olga V. Razorenova, Peiyi Wang

To Improve the Academy: A Journal of Educational Development

The COVID-19 pandemic has taken a toll on university faculty, unduly those from underrepresented groups, causing many faculty to disengage. Writing communities represent a promising tool to (re-)engage faculty and build an inclusive climate. As part of U See I Write, a faculty development initiative at the University of California, Irvine, we convened a series of monthly writing retreats between March and June of 2021, with between-retreat weekly writing sessions in smaller groups and an expectation to write daily for at least 30 minutes. In a diverse cohort of 34 faculty writers, program participation resulted in a significant increase in …

Impacts Of Campus Disruption On Educational Developers’ Role-Identity And Teamwork, William V. Pilny, Benjamin Brock, Stephanie Laggini Fiore

To Improve the Academy: A Journal of Educational Development

In times of crises, educational developers (EDs) work to ameliorate the teaching- and learning-related impacts caused by campus-wide disruptions such as health-related emergencies, mass shootings, and environmental disasters. These incidents may impact the personal-psychological factors and processes of EDs that, in turn, influence their engagement with team members and faculty. Given the vital role EDs play in improving faculty teaching and student learning across higher education (Dawson et al., 2010; Grupp, 2014; Schroeder et al., 2010), understanding the impacts of campus-wide disruptions on their functioning is critical. The present, novel study uses a psychological-phenomenological methodology and the Dynamic Systems Model …

Nebraska Center for Research on Children, Youth, Families, and Schools: Faculty Publications

The use of data to inform instruction has been linked to improved student outcomes, early identification of intervention needs, and teacher decision-making and efficacy. Additionally, data are used as a means of accountability within educational settings. However, little is known about data use practices among early grades teachers. The purpose of the current study is to describe the data use of PreK to third grade teachers and to investigate differences in data use and support across grade levels. Participants were 307 early childhood teachers in PreK and early elementary school. Analysis of survey data revealed, overall, most teachers across grade …

Community Well-Being And Civil Discourse In Nonmetropolitan Nebraska, Rebecca J. Vogt, Heather Akin, Cheryl A. Burkhart-Kriesel, Bradley D. Lubben, L. J. Mcelravy, Timothy Meyer, Steven A. Schulz

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 two 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, this year that trend reversed back to the typical pattern. This year, more 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 people believe their community will …

Optimizing Crop Productivity And Fertility Practices In Intermediate Wheatgrass, Roberta Bianchin Rebesquini

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

The intensive management associated with many annual crops often includes recurring tillage, fertilization, and pesticide applications, which contribute to environmental concerns such as water pollution and soil erosion. Intermediate wheatgrass (Thinopyrum intermedium), recognized under the trade name Kernza®, is a perennial grass that can be managed to produce grain and biomass while providing desired environmental benefits such as soil conservation and nutrient cycling. There has been limited research on best management practices and crop productivity for this alternative dual-use crop in Nebraska. A field experiment was conducted beginning in 2021 to assess nitrogen (N), phosphorus (P), and potassium …

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

Integrated crop-livestock systems are promoted as an alternative for sustainable intensification of food production. They have the potential to offer enhanced input efficiency and maintain a diversified livelihood which plays an important role in building resilience of agricultural systems. This work aims to evaluate the technical efficiency of “Integrated Crop-Livestock Systems” (ICLS), “Specialized Livestock Systems” (SLS) and “Specialized Cropping Systems” (SCS) and to identify the determinants behind inefficiencies in these systems. It also aims to assess the resilience against climate variability and market fluctuations. The first chapter provides a comparative analysis and an overview of technical efficiency assessment of farming …

Limited Accumulation And Persistence Of An Influenza A Virus In Tadpole Snails (Physa Spp.), Paul T. Oesterle, J. Jeffrey Root, Darcy S.O. Mora, Heather Schneider, Alan B. Franklin, Kathryn P. Huyvaert

United States Department of Agriculture Wildlife Services: Staff Publications

Waterfowl infected with avian influenza A viruses (IAVs) shed infectious virus into aquatic environments, providing a mechanism for transmission among waterfowl, while also exposing the entire aquatic ecosystem to the virus. Aquatic invertebrates such as freshwater snails are likely exposed to IAVs in the water column and sediment. Freshwater snails comprise a significant portion of some waterfowl species’ diets, so this trophic interaction may serve as a novel route of IAV transmission. In these experiments, tadpole snails (Physa spp.) were exposed to a low-pathogenicity IAV (H3N8) to determine whether snails can accumulate the virus and, if so, how long virus …

Lenoch, Mary Lea Killian, Christina Leyson, Sarah N. Bevins, Krista Dilione, Hon S. Ip, David E. Stallknecht, Rebecca L. Poulson, David L. Suarez, David E. Swayne, Mary J. Pantin-Jackwood

United States Department of Agriculture Wildlife Services: Staff Publications

Highly pathogenic avian influenza viruses (HPAIVs) of the A/goose/Guangdong/1/1996 lineage H5 clade 2.3.4.4b continue to have a devastating effect on domestic and wild birds. Full genome sequence analyses using 1369 H5N1 HPAIVs detected in the United States (U.S.) in wild birds, commercial poultry, and backyard flocks from December 2021 to April 2022, showed three phylogenetically distinct H5N1 virus introductions in the U.S. by wild birds. Unreassorted Eurasian genotypes A1 and A2 entered the Northeast Atlantic states, whereas a genetically distinct A3 genotype was detected in Alaska. The A1 genotype spread westward via wild bird migration and reassorted with North American …

Predicted Structure And Analysis Of The Glycoprotein From Sars-Cov-2 Variants Of Interest, Boris Shabaltiy

Honors Program: Senior Projects (Public)

SARS-CoV-2 has had a devastating effect on the world, and while the public concern and severity of the diseased caused by it have decreased, it is still crucial to monitor the virus for mutations so we can rapidly identify new variants of concern, and then rapidly prepare new vaccines and treatments. The SARS-CoV-2 spike (S) protein from the first isolates of the virus (root variant) was structurally characterized in early 2021. The spike protein structure, designated 7CZW, was uploaded to RCSB Protein Data Bank (RCSB PDB). All subsequent mutations the S protein has accumulated are based on the amino acid …

Beneath The Surface: An Investigation Into The Relation Between Power, Dehumanization, And Objectification In And Initial Social Interaction, Lillian Hefner

Honors Program: Senior Projects (Public)

Objectification theory suggests that women are disproportionately affected by objectification leading them to experience more negative health outcomes such as depression and eating disorders. Further research on objectification and synthesis of leading theories in the area suggest that power may be one factor likely to predict the objectification and dehumanization of women. One important dimension of this objectification and dehumanization is the environment in which it occurs. Few studies examine a social/dating context as the current study does. We expected the men in the study who felt a stronger sense of power during the interaction would exhibit more objectification of …

Existing Evidence For Influenza B Virus Adaptations To Drive Replication In Humans As The Primary Host, Matthew J. Pekarek, Eric A. Weaver

Nebraska Center for Virology: Faculty Publications

Influenza B virus (IBV) is one of the two major types of influenza viruses that circulate each year. Unlike influenza A viruses, IBV does not harbor pandemic potential due to its lack of historical circulation in non-human hosts. Many studies and reviews have highlighted important factors for host determination of influenza A viruses. However, much less is known about the factors driving IBV replication in humans. We hypothesize that similar factors influence the host restriction of IBV. Here, we compile and review the current understanding of host factors crucial for the various stages of the IBV viral replication cycle. While …

Did Cover Crop Or Animal Manure Ameliorate Corn Residue Removal Effects On Soil Mechanical Properties After 10 Years?, Hans W. Klopp, Humberto Blanco-Canqui, Michael Sindelar, Virginia L. Jin, Marty R. Schmer, Richard B. Ferguson

Department of Agronomy and Horticulture: Faculty Publications

Crop residue removal may negatively affect soil mechanical properties, which are key components of soil quality. To evaluate potential long-term effects, we assessed the 10-yr impact of corn (Zea mays L.) residue removal (59 % of non-grain biomass annually) on surface soil mechanical properties (0–20 cm). We also evaluated whether adding carbon (C) amendments, such as using a winter rye (Secale cereale L.) cover crop or surface-applying cattle manure (24 Mg ha− 1 biannually) can ameliorate the effects of crop residue removal. This long-term study was under irrigated no-till continuous corn on a silt loam soil in south-central …

Turnover, Megan Paul, Sarah Stepanek

Umbrella Summaries

What is turnover?

The definition of turnover tends to somewhat vary in practice and research. The most common element is an employee leaving their job. Beyond that, turnover can be further defined as internal vs. external, voluntary vs. involuntary, functional vs. dysfunctional, and avoidable vs. unavoidable.

• Internal vs. external: Internal turnover means that the employee moves to a different job within the organization, whereas external means that the employee leaves the organization altogether. In child welfare, however, the “organization” may be defined as all of state or county government, which means that a lot of movement is considered internal.
• Voluntary …

Gender Differences In Graduate Student Views On The Professional Climate In Economics, Ann Mari May, Mary G. Mcgarvey, Muazzam Toshmatova

Department of Economics: Faculty Publications

This research examines graduate student's views on the professional climate in economics using a comprehensive survey of students enrolled in economics Ph.D. programs in the United States. Topics discussed include stress and work/life balance, disciplinary climate in the profession, departmental climate, and the prevalence of sexual harassment. We find significant gender differences in views on all four topics—particularly in views on departmental climate and disciplinary climate in the profession. We analyze the results based on gender, rank of the institution, public versus private institutional status, and representation of women faculty in departments.

Although several reports have hypothesized that exercise may increase skeletal muscle protein lactylation, empirical evidence in humans is lacking. Thus, we adopted a multifaceted approach to examine if acute and subchronic resistance training (RT) altered skeletal muscle protein lactylation levels. In mice, we also sought to examine if surgical ablation-induced plantaris hypertrophy coincided with increases in muscle protein lactylation. To examine acute responses, participants’ blood lactate concentrations were assessed before, during, and after eight sets of an exhaustive lower body RT bout (n = 10 trained college-aged men). Vastus lateralis biopsies were also taken before, 3-h post, and 6-h post-exercise …

Prostate cancer (PCa) is the most common cause of cancer death among African men. The presence of tumor-specific variations in cell-free DNA (cfDNA), such as mutations, microsatellite instability, and DNA methylation, has been explored as a source of biomarkers for cancer diagnosis. In this study, we investigated the diagnostic role of cfDNA among South African PCa patients. We performed whole exome sequencing (WES) of urinary cfDNA. We identified a novel panel of 31 significantly deregulated somatic mutated genes between PCa and benign prostatic hyperplasia (BPH). Additionally, we performed whole-genome sequencing (WGS) on matching PCa and normal prostate tissue in an …

Secondary Traumatic Stress: Definitions, Measures, Predictors, And Interventions, Anita Barbee, Lisa Purdy, Michael Cunningham

Other QIC-WD Products

Child welfare professionals are exposed to a lot of traumatic events. They may experience trauma first-hand witnessing the negative experiences of children and families on their caseload or it may be experienced second-hand through the stories shared by clients or co-workers, or information being read in a file. The research has a variety of terms for this phenomenon (as described in this brief) but the evidence is clear: child welfare workers experience trauma as an occupational hazard and that exposure can manifest itself in ways similar to post-traumatic stress disorder (e.g., disrupted sleep, difficulty concentrating). In fact, a survey of …

Myocarditis is a predominant cause of congestive heart failure and sudden death in children and young adolescents that can lead to dilated cardiomyopathy. Lymphocytic myocarditis mediated by T cells can result from the recognition of cardiac antigens that may involve CD4 or CD8 T cells or both. In this report, we describe the generation of T cell receptor (TCR) transgenic mice on a C57BL/6 genetic background specific to cardiac myosin heavy chain (Myhc)-α 334–352 and make the following observations: First, we verified that Myhc-α 334–352 was immunogenic in wild-type C57BL/6 mice and induced antigen-specific CD4 T cell responses despite being …

Centromeres are epigenetically specified by the histone H3 variant CENP-A. Although mammalian centromeres are typically associated with satellite DNA, we previously demonstrated that the centromere of horse chromosome 11 (ECA11) is completely devoid of satellite DNA. We also showed that the localization of its CENP-A binding domain is not fixed but slides within an about 500 kb region in different individuals, giving rise to positional alleles. These epialleles are inherited as Mendelian traits but their position can move in one generation. It is still unknown whether centromere sliding occurs during meiosis or during development. Here, we first improve the sequence …

Single activation of peroxymonosulfate (PMS) in a homogeneous system is sometimes insufficient for producing reactive oxygen species (ROS) for water treatment applications. In this work, manganese spinel ferrite and graphitic carbon nitride (MnFe₂O₄/g-C₃N₄; MnF) were successfully used as an activator for PMS under visible light irradiation to remove the four-mostdetected- hormone-contaminated water under different environmental conditions. The incorporation of g-C₃N₄ in the nanocomposites led to material enhancements, including increased crystallinity, reduced particle agglomeration, amplified magnetism, improved recyclability, and increased active surface area, thereby facilitating the PMS activation and electron …
