Two small scale RED devices produced consistent power for up to three to ten days, depending on the device design. A two-fold decrease …

Exploring Parent Perception Of Adverse Childhood Experiences Screening In Pediatric Primary Care: A Clinical Inquiry Project, Kathryn Stevens

The Eleanor Mann School of Nursing DNP Capstone Projects

This manuscript explores the incidence and implications of Adverse Childhood Experiences (ACEs) and outlines a project assessing parental perception of their own ACEs screening during their child’s wellness visit. ACEs are adversarial events occurring during childhood, which may be chronic or singular. Abuse, neglect, and household dysfunction result in negative outcomes, including compromised neurological development and cognitive behaviors, developmental delays, poor lifestyle choices, and reduced mental and physical health. Additionally, a growing body of literature supports the impaired parenting skills in those with a history of ACEs. This can perpetuate intergenerational trauma, deprived opportunities, and poor familial health. Despite the …

Phytogenic Water Additives Improve Broiler Growth Performance Via Modulation Of Intermediary Metabolism-Related Signaling Pathways, Joshua J. Flees, Nima K. Emami, Elizabeth Greene, Bhaskar Ganguly, Sami Dridi

Poultry Science Faculty Publications and Presentations

A ban on the use of antibiotic growth promoters (AGPs) has fueled and promoted scientific research towards the identification of reliable and effective alternatives. The supplementation of phytogenics AV/SSL12 (AVSSL) and Superliv Gold (SG) in water has been shown to improve broiler feed efficiency (FE) via modulation of hypothalamic neuropeptides. However, their effects on peripheral metabolic pathways are still unknown. The present study was undertaken to determine the effects of AVSSL and SG on lipid and protein metabolism-associated pathways in various tissues. Day-old male Cobb 500 chicks (n = 288) were randomly assigned to 3 treatment groups, with 8 …

Whole-Body Acute Contact Toxicity Of Formulated Insecticide Mixtures To Blue Orchard Bees (Osmia Lignaria), Joseph Belsky, David J. Biddinger, Neelendra K. Joshi

Entomology and Plant Pathology Faculty Publications and Presentations

Blue orchard bees, [Osmia lignaria (Say) (Hymenoptera: Megachilidae)], have been developed as an important pollinator for orchard crops in North America over the last 40 years. The toxicity of several pesticides to O. lignaria and other Osmia species has been previously reported. However, the field-realistic toxicity of formulated premix insecticides comprised of multiple active ingredients (each with a different mode of action) to O. lignaria has not been assessed. Here, we use a customized spray tower in a laboratory setting to assess adult male and female whole-body direct contact exposure to four formulated pesticide mixtures: thiamethoxam + lambda-cyhalothrin (TLC), …

Race And Ethnicity, Gender, And Age On Perceived Threats And Fear Of Covid-19: Evidence From Two National Data Sources, Michael D. Niño, Casey Harris, Grant Drawve, Kevin M. Fitzpatrick

Sociology and Criminology Faculty Publications and Presentations

Previous studies find preventative behaviors designed to reduce the number of infections during emerging disease outbreaks are associated with perceived risk of disease susceptibility. Few studies have attempted to identify underlying factors that explain differences in perceptions of risk during an infectious disease outbreak. Drawing from two early waves of American Trends Panel (n=7,441), as well as a National Science Foundation funded, Qualtrics national panel survey from the early stages of the pandemic (n=10,368), we test whether race and ethnicity, gender, and age were associated with six perceived threat and fear outcomes related to COVID-19.

Conserved And Divergent Aspects Of Robo Receptor Signaling And Regulation Between Drosophila Robo1 And C. Elegans Sax-3, Trant Daiber, Christine J. Vanderzwan-Butler, Greg J. Bashaw, Timonthy A. Evans

Biological Sciences Faculty Publications and Presentations

The evolutionarily conserved Roundabout (Robo) family of axon guidance receptors control midline crossing of axons in response to the midline repellant ligand Slit in bilaterian animals including insects, nematodes, and vertebrates. Despite this strong evolutionary conservation, it is unclear whether the signaling mechanism(s) downstream of Robo receptors are similarly conserved. To directly compare midline repulsive signaling in Robo family members from different species, here we use a transgenic approach to express the Robo family receptor SAX-3 from the nematode Caenorhabditis elegans in neurons of the fruit fly, Drosophila melanogaster. We examine SAX-3’s ability to repel Drosophila axons from the …

Chemistry & Biochemistry Faculty Publications and Presentations

A new force field has been created for simulating hydrated alanine polypeptides using the adaptive force matching (AFM) method. Only density functional theory calculations using the Perdew–Burke–Ernzerhof exchange–correlation functional and the D3 dispersion correction were used to fit the force field. The new force field, AFM2020, predicts NMR scalar coupling constants for hydrated homopolymeric alanine in better agreements with experimental data than several other models including those fitted directly to such data. For Ala₇, the new force field shows about 15% helical conformations, 20% conformation in the β basin, and 65% polyproline II. The predicted helical population of …

Evidence Of Mitochondrial Dysfunction In Bacterial Chondronecrosis With Osteomyelitis–Affected Broilers, Alison Ferver, Elizabeth S. Greene, Robert F. Wideman Jr., Sami Dridi

Poultry Science Faculty Publications and Presentations

A leading cause of lameness in modern broilers is bacterial chondronecrosis with osteomyelitis (BCO). While it is known that the components of BCO are bacterial infection, necrosis, and inflammation, the mechanism behind BCO etiology is not yet fully understood. In numerous species, including chicken, mitochondrial dysfunction has been shown to have a role in the pathogenicity of numerous diseases. The mitochondria is a known target for intracellular bacterial infections, similar to that of common causative agents in BCO, as well as a known regulator of cellular metabolism, stress response, and certain types of cell death. This study aimed to determine …

Background

Interest in the use of natural feed additives as an alternative to antimicrobials in the poultry industry has increased in recent years because of the risk of bacterial resistance. One of the most studied groups are polyphenolic compounds, given their advantages over other types of additives and their easy potentiation of effects when complexes are formed with metal ions. Therefore, the objective of the present study was to evaluate the impact of dietary supplementation of copper acetate (CA), curcumin (CR), and their combination (CA-CR) against Salmonella Typhimurium colonization, intestinal permeability, and cecal microbiota composition in broiler chickens through a …

Fecundity And Seed Dormancy Variation Within And Among Echinochloa Species, Hussain Tahir, Nilda Roma-Burgos

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

The Echinochloa genus contains two of the world's top five worst weeds. The persistence and weediness of Echinochloa spp. are partly due to its seed longevity and variable seed dormancy. In the USA, specifically in Arkansas, multiple species infest the same field in many cases. Persistence could vary across species and dormancy affects infestation level. Studies were conducted to evaluate the seed production potential and dormancy of Echinochloa species in the State. Ninety-four accessions were characterized in a common garden in Fayetteville, Arkansas, USA. The species were Echinochloa colona (L.) Link, E. crus-galli (L.) P. Beauv, E. muricata P. …

Prevailing Theories Of Over-Imitation, Christa Griffith

2021 Honors Symposium

Imitation is a naturally occurring process of human development where individuals can learn different skills and behaviors by mimicking those around them. Imitation plays a vital role in the development of cognitive and social communication behaviors such as language and joint attention. Although imitation appears to have a clear positive utilization there are instances where its utility is reduced. Over-imitation is the process of an individual imitating actions even when those actions are not causally relevant to the objective to the task. Whiten et al. (2016) said that “the occurrence of overimitation in the real world, maximizes the power of …
