Nebraska Water Center: Faculty Publications

Background: COVID-19 has caused nearly 1 million deaths in the United States, not to mention job losses, business and school closures, stay-at-home orders, and mask mandates. Many people have suffered increased anxiety and depression since the pandemic began. Not only have mental health symptoms become more prevalent, but alcohol consumption has also increased during this time. Helplines offer important insight into both physical and mental wellness of a population by offering immediate, anonymous, cheap, and accessible resources for health and substance use disorders (SUD) that was unobstructed by many of the mandates of the pandemic. Further, the pandemic also …

Genomics Reveals A New Genus And Species From A Single Female Specimen (Lepidoptera: Hesperiidae: Hesperiinae: Hesperiini: Moncina), Ernst Brockmann, Jing Zhang, Qian Cong, Nick V. Grishin

Insecta Mundi

New taxa in Hesperiidae (Lepidoptera: Papilionoidea) are traditionally proposed after inspection of male genitalia, which largely form the basis for Hesperiidae taxonomy. However, with genomic DNA se­quencing, even a single female specimen can be placed in a phylogenetic context of existing classification and taxonomically assigned with confidence. Genomic sequencing of an unusually patterned Hesperiidae female from San Martin, Peru, characterized by pearly spots outlining an inverted heart pattern on the rust-colored ventral hindwing, reveals that it represents an undescribed genus and species named here as Gemmia buechei Brockmann and Grishin, new genus and new species.

A Nanofiber-Embedded Microfluidic Platform For Studying Neurobiology, Donghee Lee, Navatha Shree Sharma, S. M. Shatil Shahriar, Kai Yang, Zheng Yan, Jingwei Xie

Department of Mechanical and Materials Engineering: Faculty Publications

Due to their biomimetic properties, electrospun nanofibers have been widely used in neurobiology studies. However, mechanistic understanding of cell-nanofiber interactions is challenging based on the current in vitro culture systems due to the lack of control of spatiotemporal patterning of cells and difficulty in monitoring single cell behavior. To overcome these issues, we apply microfluidic technology in combination with electrospun nanofibers for in vitro studies of interactions between neurons and nanofiber materials. We demonstrate a unique nanofiber embedded microfluidic device which contains patterned aligned or random electrospun nanofibers as a new culture system. With this device, we test how different …

Emotional Perspectives On Existential Threat: Evaluating The Rationality Of Climate Anxiety, Rachael Lange

Honors Program: Senior Projects (Public)

This thesis seeks to answer the following question: Is climate anxiety a rational emotion? In order to arrive at an answer, several queries embedded in the main question must be addressed. This paper will outline a theory of emotion in order to define anxiety, assess climate change as a specific emotional object, and compare the rationality of anxiety using two evaluative standards. Climate anxiety is an emerging emotional phenomenon experienced in response to the perceived detrimental effects of a warming climate. Due to the novel identification of this contemporary emotional phenomenon with the established emotion of anxiety, there has thus …

Anderson, Ronald J. Nachman, Yoonseong Park

Department of Entomology: Faculty Publications

The devastating Varroa mite (Varroa destructor Anderson and Trueman) is an obligatory ectoparasite of the honey bee, contributing to significant colony losses in North America and throughout the world. The limited number of conventional acaricides to reduce Varroa mites and prevent disease in honey bee colonies is challenged with wide-spread resistance and low target-site selectivity. Here, we propose a biorational approach using comparative genomics for the development of honey beesafe and selective acaricides targeting the Varroa mite-specific neuropeptidergic system regulated by proctolin, which is lacking in the honey bee. Proctolin is a highly conserved pentapeptide RYLPT (Arg-Tyr-Leu-Pro-Thr) known to …

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Considering the increasing demand for urban water and the low water-use efficiency in the agricultural sector, an exchange of treated urban wastewater for agricultural water could be a fundamental solution for administering sustainable management of water resources. However, implementing the intersectoral water exchange project is influenced by the economic, social, and environmental conditions of each region, especially in developing countries. Therefore, this study sought to identify the best possible strategies for exchanging treated urban wastewater for agricultural water in Mashhad city, located in Iran, a country that suffers from decreased urban water resources. Based on the interviews conducted with the …

Participatory approaches to science and decision making, including stakeholder engagement, are increasingly common for managing complex socio-ecological challenges in working landscapes. However, critical questions about stakeholder engagement in this space remain. These include normative, political, and ethical questions concerning who participates, who benefits and loses, what good can be accomplished, and for what, whom, and by who. First, opportunities for addressing justice, equity, diversity, and inclusion interests through engagement, while implied in key conceptual frameworks, remain underexplored in scholarly work and collaborative practice alike. A second line of inquiry relates to research–practice gaps. While both the practice of doing engagement …

Bovine respiratory disease (BRD) is the primary animal health concern facing feedlot producers. Many antimicrobial mitigation strategies are available, but few studies have compared feedlot performance during both the receiving and finishing periods following application of different antimicrobials used as metaphylaxis at arrival. The objective of this study was to compare antimicrobial metaphylaxis methods on clinical health and growth performance across both the receiving and finishing periods. A total of 238 multiple-sourced steers in two source blocks were used in a generalized complete block design. The four treatments included: 1) a negative control, 5 mL of sterile saline injected subcutaneously …

Activity Of The Lactate Dehydrogenase Inhibitor Oxamic Acid Against The Fermentative Bacterium Streptococcus Mitis/Oralis: Bactericidal Effects And Prevention Of Daptomycin Resistance In Vitro And In An Ex Vivo Model, Razieh Kebriaei, Arnold S. Bayer, Christian K. Lapitan, Michael J. Rybak, Greg A. Somerville, Nagendra N. Mishra

School of Veterinary and Biomedical Sciences: Faculty Publications

Streptococcus mitis/oralis is a fermentative bacterium that relies on lactate dehydrogenase to balance its redox poise and keep glycolysis active. Metabolomic analysis of an in vitro– derived daptomycin-resistant (DAP-R) S. mitis/oralis strain (351-D10) revealed differences in glucose catabolism relative to its DAP-susceptible (DAP-S) parental strain, 351. Metabolic changes associated with the transition to this DAP-R phenotype suggested that inhibiting glycolysis could alter DAP susceptibility. In addition, the strong reliance of S. mitis/oralis on glycolysis for energy and biosynthetic intermediates suggested that inhibiting glycolysis would adversely affect growth and biomass accumulation. To test these hypotheses, we used the lactate dehydrogenase inhibitor …

Agronomic And Quality Impact Of A Shortened Translocation For Wheat Streak Mosaic Virus Resistance, Mary J. Guttieri, Robert L. Bowden, Guorong Zhang, Scott Haley, Katherine Anna Frels, Gary L. Hein, Katherine W. Jordan

Department of Agronomy and Horticulture: Faculty Publications

Wheat streak mosaic virus (WSMV) is a mite-vectored virus with substantial economic impact on wheat production. One of the effective sources of resistance to WSMV, Wsm1, is carried on a translocation from Thinopyrum intermedium. The original whole arm form of this translocation (T4DL·4JsS) was highly effective against WSMV but carried a substantial yield penalty in the absence of the virus. Shorter recombinants of the Th. intermedium translocation are now available. This study characterized the agronomic performance of near-isogenic sib-pair families in 10 yield trials using one of these shortened T4DL·4DS-4J^sS translocations, named “rec213,” in the absence …

Role Of Bifidobacterium Pseudocatenulatum In Degradation And Consumption Of Xylan-Derived Carbohydrates, Elizabeth Drey, Car Reen Kok, Robert Hutkins

Department of Food Science and Technology: Faculty Publications

Xylans, a family of xylose-based polysaccharides, are dietary fibers resistant to digestion. They therefore reach the large intestine intact; there, they are utilized by members of the gut microbiota. They are initially broken down by primary degraders that utilize extracellular xylanases to cleave xylan into smaller oligomers. The resulting xylooligosaccharides (XOS) can either be further metabolized directly by primary degraders or cross-feed secondary consumers, including Bifidobacterium. While several Bifidobacterium species have metabolic systems for XOS, most grow poorly on longer- chain XOS and xylan substrates. In this study, we isolated strains of Bifidobacterium pseudocatenulatum and observed that some, including …

The Emergence Of Convergence, Shana M. Sundstrom, David G. Angeler, Jessica G. Ernakovich, Jorge H. Garcıá, Joseph A. Hamm, Orville Huntington, Craig R. Allen

School of Natural Resources: Faculty Publications

Science is increasingly a collaborative pursuit. Although the modern scientific enterprise owes much to individuals working at the core of their field, humanity is increasingly confronted by highly complex problems that require the integration of a variety of disciplinary and methodological expertise. In 2016, the U.S. National Science Foundation launched an initiative prioritizing support for convergence research as a means of “solving vexing research problems, in particular, complex problems focusing on societal needs.” We discuss our understanding of the objectives of convergence research and describe in detail the conditions and processes likely to generate successful convergence research. We use our …

While much of the quantitative research on Black women faculty has taken a comparative approach to understanding their experiences, this study provides a counternarrative, centering their experiences as faculty. This large-scale, multi-institution glance at Black women faculty helps to give us an overview of these women across the country, looking at who they are, where they are, how they spend their time, and what they value in undergraduate education. This study allows us to strengthen various arguments made in qualitative studies of Black women faculty and amplify their perspectives and experiences. Furthermore, it reaffirms and reinvigorates the need for educational …

Data-Driven Iterative Refinements To Educational Development Services: Directly Measuring The Impacts Of Consultations On Course And Syllabus Design, Chad Hershock, Laura Ochs Pottmeyer, Jessica Harrell, Sophie Le Blanc, Marisella Rodriguez, Jacqueline Stimson, Katherine Phelps Walsh, Emily Daniels Weiss

To Improve the Academy: A Journal of Educational Development

Evidence-based practice in educational development includes leveraging data to iteratively refine center for teaching and learning (CTL) services. However, CTL data collection is often limited to counts and satisfaction surveys rather than direct measures of outcomes. To directly assess impacts of consultations on course and syllabus design, we analyzed 94 clients’ syllabi (32 faculty, 62 graduate students and postdocs) before and after consultations. Faculty and non-faculty clients demonstrated significant change following consultations (6% and 10% gains in syllabus rubric scores, representing 50% and 31% of possible gains and effect sizes of 0.73 and 1.04 standard deviations, respectively). We compared faculty …

A Case Study In Teaching Inclusive Teaching, Zitsi Mirakhur, Christopher Chen, Sarah Schwarz

To Improve the Academy: A Journal of Educational Development

As the college student population grows increasingly diverse, there is a need for instructors—including graduate student instructors (GSIs)—to have a set of pedagogical tools that enables them to create inclusive classroom environments, those that consider their students’ identity and provide equal opportunities for learning. However, the literature on how to support GSIs develop these skills is still nascent. In this article, we report on two strategies—one diffuse and one direct—we used while training GSIs and the ways in which they changed GSIs’ understanding of what inclusive teaching entails. We find that our direct model might have increased GSIs’ awareness of …
