Dogs have a special place in human history as the first domesticated species and play important roles in many cultures around the world. However, their role in scientific studies has been relatively recent. With a few notable exceptions (e.g., Darwin, Pavlov, Scott, and Fuller), domestic dogs were not commonly the subject of rigorous scientific investigation of behavior until the late 1990s. Although the number of canine science studies has increased dramatically over the last 20 years, most research groups are limited in the inferences they can draw because of the relatively small sample sizes used, along with the exceptional diversity …

Genetic Control Of Photoprotection And Photosystem Ii Operating Efficiency In Plants, Seema Sahay, Marcin Grzybowski, James Schnable, Katarzyna Głowacka

Department of Biochemistry: Faculty Publications

• Photoprotection against excess light via nonphotochemical quenching (NPQ) is indispensable for plant survival. However, slow NPQ relaxation under low light conditions can decrease yield of field-grown crops up to 40%.

• Using semi-high-throughput assay, we quantified the kinetics of NPQ and photosystem II operating efficiency (ΦPSII) in a replicated field trial of more than 700 maize (Zea mays) genotypes across 2 yr. Parametrized kinetics data were used to conduct genome-wide association studies.

• For six candidate genes involved in NPQ and ΦPSII kinetics in maize the loss of function alleles of orthologous genes in Arabidopsis (Arabidopsis thaliana) …

Genome-Wide Investigation Of Snrk2 Gene Family In Two Jute Species: Corchorus Olitorius And Corchorus Capsularis, Borhan Ahmed, Fakhrul Hasan, Anika Tabassum, Rasel Ahmed, Rajnee Hassan, Ruhul Amin, Mobashwer Alam

Department of Biochemistry: Faculty Publications

Background Sucrose non-fermenting-1 (SNF1)-related protein kinase 2 (SnRK2), a plant-specifc serine/threonine kinase family, is associated with metabolic responses, including abscisic acid signaling under biotic and abiotic stresses. So far, no information on a genome-wide investigation and stress-mediated expression profling of jute SnRK2 is available. Recent whole-genome sequencing of two Corchorus species prompted to identify and characterize this SnRK2 gene family.

Result We identifed seven SnRK2 genes of each of Corchorus olitorius (Co) and C. capsularis (Cc) genomes, with similar physico-molecular properties and sub-group patterns of other models and related crops. In both species, the SnRK2 gene …

Structural Basis Of Dna Binding By The Whib-Like Transcription Factor Whib3 In Mycobacterium Tuberculosis, Tao Wan, Magdaléna Horová, Vimmy Khetrapal, Shanren Li, Camden Jones, Andrew Schacht, Xinghui Sun, Limei Zhang

Department of Biochemistry: Faculty Publications

Mycobacterium tuberculosis (Mtb) WhiB3 is an iron–sulfur cluster-containing transcription factor belonging to a subclass of the WhiB-Like (Wbl) family that is widely distributed in the phylum Actinobacteria. WhiB3 plays a crucial role in the survival and pathogenesis of Mtb. It binds to the conserved region 4 of the principal sigma factor (σ^A₄) in the RNA polymerase holoenzyme to regulate gene expression like other known Wbl proteins in Mtb. However, the structural basis of how WhiB3 coordinates with σ^A₄ to bind DNA and regulate transcription is unclear. Here we determined crystal structures …

Complab V1.0: A Scalable Pore-Scale Model For Flow, Biogeochemistry, Microbial Metabolism, And Biofilm Dynamics, Heewon Jung, Hyun-Seob Song, Christof Meile

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Microbial activity and chemical reactions in porous media depend on the local conditions at the pore scale and can involve complex feedback with fluid flow and mass transport. We present a modeling framework that quantitatively accounts for the interactions between the bio(geo)chemical and physical processes and that can integrate genome-scale microbial metabolic information into a dynamically changing, spatially explicit representation of environmental conditions. The model couples a lattice Boltzmann implementation of Navier–Stokes (flow) and advection–diffusion-reaction (mass conservation) equations. Reaction formulations can include both kinetic rate expressions and flux balance analysis, thereby integrating reactive transport modeling and systems biology. We also …

Evaluation Of Cytocompatability And Safety Of Nerve Retraction Compounds For Local Disc Denervation To Treat Disc-Associated Low Back Pain, Fei San Lee, Uyen N. Nguyen, Rebecca A. Wachs

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Low back pain (LBP) is the leading cause of disability worldwide. Aberrant nerve growth into intervertebral discs is a common pathological feature of disc-associated LBP. Current treatments rely on short-term solutions using opioids or anti-inflammatory prescriptions which can lead to addiction and side effects, respectively. We hypothesize that removal of aberrant nerve fibers in the disc using nerve retraction compounds can alleviate discassociated LBP. We performed screening of nerve retraction compounds using adult rat dorsal root ganglia (DRG) explant culture in hydrogels to mimic disc innervation in vitro. Capsaicin, known to induce nerve retraction, was used as a positive control …

A Methodology To Optimize Site-Specific Field Capacity And Irrigation Thresholds, Hemendra Kumar, Puneet Srivastava, Jasmeet Lamba, Bruno Lena, Efstathios Diamantopoulos, Brenda Ortiz, Bijoychandra Takhellambam, Guilherme Morata, Luca Bondesan

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The determination of field capacity (FC), irrigation thresholds, and irrigation amounts is characterized by site-specific soil hydraulic properties (SHPs). This study, conducted in two zones (zone 1 and zone 2) delineated based on soil, topography, and historical crop yield in Alabama (USA), focused on determining zone-specific FC using negligible drainage flux (q_fc) criterion. The HYDRUS-1D model was used to optimize zone-specific SHPs using measured soil matric potential (h). The zone-specific FCs were determined using optimized and raw SHPs at 0.01 cm/day as q_fc. The results showed that the optimized FC at q_{fc …}

Agricultural Machinery Operator Monitoring System (Ag-Oms): A Machine Learning Approach For Real-Time Operator Safety Assessment, Terence Irumva, Herve Mwunguzi, Santosh Pitla, Bethany Lowndes, Aaron Yoder, Ka-Chun Siu

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The 2015 CS-CASH (Central States Center for Agricultural Safety and Health, 2015) Injury Surveillance Surveys showed that around 19% of injuries to agricultural producers are related to tractors or large agricultural machinery, yet only a limited number of studies are found that address tools and methods for monitoring safety behaviors of agricultural machinery operators in real-time. The current safety behavior monitoring approaches require an in-person presence, which can be both time- and cost-inefficient, and the other available methods lack a feedback element to alert operators in realtime. As a result, the research presented in this study aimed to develop an …

Goniometer In The Air: Enabling Brdf Measurement Of Crop Canopies Using A Cable-Suspended Plant Phenotyping Platform, Geng Bai, Yufeng Ge, Bryan Leavitt, John Gamon, David Scoby

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The Bidirectional Reflectance Distribution Function (BRDF) quantifies the distribution of the spectral reflectance of a target surface at various viewing and illumination angles. In-field measurement of the BRDF of vegetation canopies improves the characterization of offnadir measurements and informs radiative transfer models of canopy reflectance, where the Lambertian assumption does not hold. However, current field goniometers are unable to measure BRDF efficiently, especially for tall vegetation across the growing season because of the limitations of clearance, field accessibility, and flexibility of the sensor field of view. In this study, we explored the potential of using a large-scale cable-suspended field phenotyping …

Fusarium Graminearum Effector Fgnls1 Targets Plant Nuclei To Induce Wheat Head Blight, Guixia Hao, Todd A. Naumann, Hui Chen, Guihua Bai, Susan Mccormick, Hye-Seon Kim, Bin Tian, Harold N. Trick, Michael J. Naldrett, Robert Proctor

Nebraska Center for Biotechnology: Faculty and Staff Publications

Fusarium head blight (FHB) caused by Fusarium graminearum is one of the most devastating diseases of wheat and barley worldwide. Effectors suppress host immunity and promote disease development. The genome of F. graminearum contains hundreds of effectors with unknown function. Therefore, investigations of the functions of these effectors will facilitate developing novel strategies to enhance wheat resistance to FHB. We characterized a F. graminearum effector, FgNls1, containing a signal peptide and multiple eukaryotic nuclear localization signals. A fusion protein of green fluorescent protein and FgNls1 accumulated in plant cell nucleiwhen transiently expressed in Nicotiana benthamiana. FgNls1 suppressed …

Gene Regulatory Changes Underlie Developmental Plasticity In Respiration And Aerobic Performance In Highland Deer Mice, Rena M. Schweizer, Catherine M. Ivy, Chandrasekhar Natarajan, Graham R. Scott, Jay F. Storz, Zachary A. Cheviron

School of Biological Sciences: Faculty Publications

Phenotypic plasticity can play an important role in the ability of animals to tolerate environmental stress, but the nature and magnitude of plastic responses are often specific to the developmental timing of exposure. Here, we examine changes in gene expression in the diaphragm of highland deer mice (Peromyscus maniculatus) in response to hypoxia exposure at different stages of development. In highland deer mice, developmental plasticity in diaphragm function may mediate changes in several respiratory traits that influence aerobic metabolism and performance under hypoxia. We generated RNAseq data from diaphragm tissue of adult deer mice exposed to (1) life-long …

Using Drawing As A Tool For Investigating Undergraduate Conceptions Of Earth Scientists, Peggy Mcneal, Deepika Menon, Deef Allah Al Shorman, Paulina Gajewska-Schaefer

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

The purpose of this study was to investigate undergraduate students’ conceptions of Earth scientists, using drawing as a tool, during introductory Earth science courses. We explored two research questions: 1) What student conceptions are evident in undergraduate students’ drawings of Earth scientists? and 2) How do undergraduate students’ conceptions of Earth scientists—as evidenced in their drawings—change as a result of completing an introductory Earth science course? We collected pre- and post-drawings of Earth scientists from 94 students in six introductory Earth science courses at two universities and coded the 188 drawings across 39 indicators. We used Chi Square Goodness of …

Greenhouse Gas Emissions From Two Beef Systems From Birth To Slaughter In Eastern Nebraska, Levi J. Mcphillips, Zac E. Carlson, Andrew E. Suyker, J. C. Macdonald, Tala Awada, Jane Okalebo, Shree Dangal, Rick R. Stowell, Andrea K. Watson, Galen E. Erickson

Nebraska Beef Cattle Reports

Methane emissions from growing and finishing calves born into a spring calving, conventional cow system or a summer calving, partially-confined cow system were compared. Cows fed a restricted diet of corn-byproduct and grain residues in confinement produced less methane and carbon dioxide per day compared to cows grazing pasture or cover crop. Calves weaned from the confinement-based production system were smaller at weaning and compensated with greater gain during the growing phase. More days on feed in the finishing phase were needed for the calves from the confinement system to reach same backfat thickness. Over the entire growing and finishing …

Oxbridge And Core Curricula: Continuing Conversations With The Past In Honors Colleges, Christopher A. Snyder

National Collegiate Honors Council Monographs: Chapters

The American honors college, as it exists in the twenty-first century, is idiosyncratic and an amalgam of centuries old European traditions in higher education with pedagogies and practices that have emerged only since about the 1980s and are particular to America. These disparate influences coexist—sometimes uneasily—in American universities, and yet American honors colleges have continued to have conversations with the past in order to seek wisdom for dealing with contemporary issues such as the democratization of higher education, social justice and diversity, the use of instructional technology, and the controversy between vocational training and liberal learning. Because, unlike departments, an …

Should We Start An Honors College? An Administrative Playbook For Working Through The Decision, Richard Badenhausen

National Collegiate Honors Council Monographs: Chapters

The last two decades have seen significant growth in honors colleges, though the transition to that model takes many forms. This essay lays out crucial questions for stakeholders considering such a move. While highlighting material advantages that may accrue from the transition, the chapter also notes reasons for not starting an honors college; and it explores some of the new challenges that recently founded honors colleges will face. Above all, the essay frowns upon the so-called “switch out the sign over the door” approach to institutional change in favor of deliberate, thoughtful, and strategic processes that involve many stakeholders and …

The Role Of The Honors College Dean In The Future Of Honors Education, Peter Parolin, Timothy J. Nichols, Donal C. Skinner, Rebecca C. Bott-Knutson

National Collegiate Honors Council Monographs: Chapters

In this chapter, four honors deans reflect on the unique aspects of the honors dean's role. The authors argue that by being responsive to the challenges, opportunities, and responsibilities they face daily, honors deans can enable honors to deliver on its promises to students and to serve the whole university community. Attentive to changing dynamics in honors education nationwide, the authors address how deans must confront myths about honors that bear the legacy of past realities while actively tending to justice in the admissions process, to recruiting and serving diverse populations, and to supporting an honors environment that addresses the …

“It Is What You Make It”: Opportunities Arising From The Unique Roles Of Honors College Deans, Jeff Chamberlain, Thomas M. Spencer, Jefford Vahlbusch

National Collegiate Honors Council Monographs: Chapters

Grounded in the shared experiences of three current honors college deans and in comprehensive interviews with another two dozen honors deans at diverse institutions of higher education across the U.S., this chapter argues that the uniqueness of honors college dean roles and work can—and indeed should—lead to innovative and transformative change and improved student experiences, outcomes, and success, not only in honors colleges and within the scope of honors education, but across entire institutions. Ultimately the chapter contends that, while there can be manifold frustrations in running an honors college, the position of honors dean is one of the best …

Honors Colleges As Levers Of Educational Equity, Teagan Decker, Joshua Kalin Busman, Michele Fazio

National Collegiate Honors Council Monographs: Chapters

While higher education is widely imagined as a tool for social mobility, the realities of enrollment, retention, and professional trajectories betray the conservative mechanisms through which higher education too often reproduces the status quo of inequality. Honors colleges can and should strive to act as levers of equity in this scenario of entrenchment, but the nature of this project varies depending on the institution’s own class position vis-à-vis its students. Elite, highly selective institutions may advocate for enrollment strategies that target student populations that do not typically attend those institutions, but other institutions likely already enroll such students in large …

Honors Liberal Arts For The 21st Century, John Carrell, Aliza S. Wong, Chad Cain, Carrie J. Preston, Muhammad H. Zaman

National Collegiate Honors Council Monographs: Chapters

We argue that honors colleges can deploy the power of the liberal arts to emphasize diversity, equity, global citizenship, ethical leadership, and empowerment by combining liberal arts and STEM (science, technology, engineering, and medicine) fields in interdisciplinary approaches to global challenges, from climate change to the pandemic to forced displacement. As the honors colleges at Texas Tech and Boston University work to be at the forefront of pedagogical and curricular innovation, the twenty-first century has presented us with a student and faculty community becoming increasingly aware of historical, racial, gendered, and socioeconomic disparities, which were further exacerbated by the COVID …

Honors Colleges, Transdisciplinary Education, And Global Challenges, Paul Knox, Paul Heilker

National Collegiate Honors Council Monographs: Chapters

The authors contend that the most significant comparative advantage of honors colleges is the combination of gifted and motivated students from every academic discipline and interdisciplinary curricula that train students to integrate diverse perspectives. The authors discuss how to harness this advantage to provide a truly transdisciplinary education through collaborative, project-based learning, both on campus and beyond. They assert that honors colleges are in a unique position to circumvent the siloed structures of academia by convening multidisciplinary groups of students guided by faculty from a wide range of disciplines. Doing so can help reimagine undergraduate education to address urgent and …

Diversity In Honors: Understanding Systemic Biases Through Student Narratives, Aman Singla, Minerva Melendrez, Mable T. Thai, Sukhdev S. Mann, Denise Zhong, Kim T. Hoang, Isabella H. Lee, Andrea V. Aponte

Journal of the National Collegiate Honors Council Online Archive

Centered on superiority over a certain group or individual, discrimination becomes predominant in prestigious institutions that pride themselves on exclusivity. Collegiate honors programs tend to deepen this practice by creating highly elite spaces accessible only to a select few. This rigidity can lead to an underrepresentation of historically marginalized groups, students who often lack the necessary resources for achieving academic excellence. This case study examines the ways honors programs inadvertently perpetuate discrimination among different social identities. Using inductive interviewing of honors students (n = 12) to gauge individual perceptions of program diversity, researchers rely on content analysis to generate …

Resisting Disciplinarity: Curriculum Mapping And Transdisciplinarity, Megan Snider Bailey

Journal of the National Collegiate Honors Council Online Archive

American higher education relies on a taxonomy of knowledge stemming from Puritan ways of thinking and knowing—a disciplinary classification system that sorts “questions asked” and “answers possible” into epistemic categories. This paper interrogates the notion of disciplinarity to better understand the arbitrariness of epistemic divisions and the harm that these decisions cause. The author explores transdisciplinarity as an emerging concept in honors education, one which rejects boundaries and explores problems through multiple, competing perspectives. Transdisciplinary pedagogical approaches offer honors educators a mechanism for pivoting teaching and learning away from outdated assumptions of honors as elitist, giving honors students a liberating …
