Alkaloid-Based Chemical Defenses In 11 Species Of Bufonid Poison Frogs From Brazil (Bufonidae: Melanophryniscus), Emily Staufer

Masters Theses

The term ‘poison frog’ describes members of five anuran families that are capable of sequestering lipophilic, alkaloid-based chemical defenses from their prey. Alkaloid defenses can vary widely within and among poison frog species, mostly linked to differences in availability of arthropod prey at different scales. While research has mainly focused on alkaloid variation within the dendrobatid and mantellid poison frogs, bufonid poison frogs in the genus Melanophryniscus demonstrate high inter- and intra-species alkaloid variation, and some members are capable of both sequestering dietary alkaloids and synthesizing alkaloids metabolically. However, of the 31 species of Melanophryniscus, only eight have ever had …

Differential Impact Of Biological And Behavioral Traits On Postexercise Energy Intake In Men Andwomen, Christoph Höchsmann, Safiya E. Beckford, Jeffery A. French, Julie B. Boron, Jared Stevens, Karsten Koehler

Department of Psychology: Faculty Publications

The energy intake response to exercise is highly variable and energy (over-) compensation via increased post-exercise energy intake occurs in some individuals but not others. In explorative analyses, we aimed to identify biological and behavioral predictors of post-exercise ad libitum energy intake and whether these predictors differ from ad libitum energy intake after rest.

Conclusions:Post-exercise energy intake is associatedwithdifferent factors than energy intake after rest and behavioral and biological traits differentially affect post-exercise energy intake in men and women. In women, habitual exercise behavior seems to predict postexercise energy intake, protecting against compensatory eating. Inmen, appetite-regulating hormones play a role …

Chloris Gayana - Environmental Weed Risk Assessment 2022, Department Of Primary Industries And Regional Development, Western Australia

Environmental Weed Risk Assessments

Introducing new plants to an area may have both positive and negative effects on the environment, economy and community. To minimise the negative environmental impact of introducing new agricultural species, DPIRD conducts a risk assessment procedure based on widely accepted scientific standards. This report assesses Rhodes grass (Chloris gayana). Rhodes grass (Chloris gayana) is a warm season or sub-tropical (C4) perennial grass which is both tufted and has stolons (runners). The degree of stoloniferous growth not only varies between varieties but can also vary between different environments and management practices. Vegetative growth is generally 30 to 100 cm in height, …

Clitoria Ternatea - Environmental Weed Risk Assessment 2022, Department Of Primary Industries And Regional Development, Western Australia

Environmental Weed Risk Assessments

Introducing new plants to an area may have both positive and negative effects on the environment, economy and community. To minimise the negative environmental impact of introducing new agricultural species, DPIRD conducts a risk assessment procedure based on widely accepted scientific standards. This report assesses Butterfly pea (Clitoria ternatea). Butterfly pea, also called blue pea, is a short-lived perennial legume with a semi-erect woody base with fine twining stems and pinnate leaves with 5–7 leaflets. Individual plants may persist for 2–4 years but, where well adapted, have good regeneration from seed, so reseeding is usually not required in permanent pastures. …

Covid-19 Pandemic Impact On Us Childhood Caries And Potential Mitigation, Christina Scherrer, Shillpa Naavaal, Susan O. Griffin, Mei Lin

Dental Public Health and Policy Publications

Non-Hispanic Black (NHB) and Hispanic and low-income US children have a higher prevalence of untreated caries than their higher-income and non-Hispanic White (NHW) counterparts. Due to the COVID-19 pandemic, many dental offices and school sealant programs closed beginning March 2020. We examine the effect of reduced access to restorative care and sealants on the oral health of children from low-income households overall and by race/ethnicity and how increased sealant delivery in September 2022 could mitigate these effects. We used Markov chain Monte Carlo simulation to model COVID-19’s impact on first permanent molar (1M) caries incidence and loss in quality of …

Dental Public Health and Policy Publications

Objectives: To evaluate the changes in dental insurance and utilization among pregnant women before and after the pregnancy Medicaid dental benefit policy implementation in 2015 in Virginia.

Methods: We used pooled cross-sectional data from six cycles of the Virginia Pregnancy Risk Assessment Monitoring System on women aged ≥21 years. Using logistic regression models and a difference-in-difference design, we compared the effects of policy implementation on dental insurance and utilization between pre-policy (2013-2014) and post-policy period (2016-2019) among women enrolled in Medicaid (treatment, N = 1,105) vs. those with private insurance (control, N = 2,575). A p-value of 0.05 was …

Dismantling The Education-Survival Complex: A Qualitative Case Study Of How High School Youth Resist Whitestream School Policies And Foster School Change Through A Youth-Development Organization, Tracie Trinidad

Electronic Theses and Dissertations

The aim of this study is to critically examine how youth resist whitestream school policies and foster educational change through community sociopolitical youth-development organizations. The methodology for this study is a qualitative case study (Fraenkel & Wallen, 1990; Merriam, 1988), as I am focused on participant perceptions and experiences, and how they make sense of their resistance experience through participation in sociopolitical youth development organizations like Youth for Social and Political Activism (YSPA). In total, eight participants spoke about their racial identity through their lived experiences in public school and YSPA programming.

The data and analysis are presented in the …

Mitigating Weight Stigma In The Medical System: Self-Compassion For Nursing Students, Ellen C. Joseph

Electronic Theses and Dissertations

Weight stigma is a form of oppression that has been shown to have a detrimental impact on the well-being of people with higher weight. Healthcare providers are one of the most common sources of weight stigma, and their stigmatizing beliefs have been found to be associated with differential care for patients with “obesity”. The current study aimed to explore the feasibility of the loving-kindness meditation (LKM) as a brief intervention that reduces weight bias in nursing students by increasing self-compassion, positive, other-focused emotions, and cognitive flexibility, in order to improve compassionate care for patients with higher weight. Participants (189 nursing …

Reference-Free Discovery Of Nuclear Snps Permits Accurate, Sensitive Identification Of Carya (Hickory) Species And Hybrids, Robert A. Literman, Brittany M. Ott, Jun Wen, L. J. Grauke, Rachel S. Schwartz, Sara M. Handy

Biological Sciences Faculty Publications

Premise: DNA-based species identification is critical when morphological identification is restricted, but DNA-based identification pipelines typically rely on the ability to compare homologous sequence data across species. Because many clades lack robust genomic resources, we present here a bioinformatics pipeline capable of generating genome-wide single-nucleotide polymorphism (SNP) data while circumventing the need for any reference genome or annotation data. Methods: Using the SISRS bioinformatics pipeline, we generated de novo ortholog data for the genus Carya, isolating sites where genetic variation was restricted to a single Carya species (i.e., species-informative SNPs). We leveraged these SNPs to identify both full-species and hybrid …

Defining A Flexible Notion Of “Good” Stem Writing Across Contexts: Lessons Learned From A Cross-Institutional Conversation, Sara M. Grady, Jenna Morton-Aiken, Caroline Gottschalk Druschke, Ingrid E. Lofgren, Nancy E. Karraker, Scott R. Mcwilliams, Nedra Reynolds, Elaine Finan, Patti L. Wolter, Donna R. Leff, Michael Kennedy

Natural Resources Science Faculty Publications

We respond to a surging interest in science communication training for graduate scientists by advocating for a focus on rhetorically informed approaches to STEM writing and its assessment. We argue that STEM communication initiatives would benefit by shifting from a strategic focus on products to a flexible understanding of writing as a practice worthy of attention and study. To do that, we use our experience across two universities and two distinct programmatic contexts to train STEM graduate students in writing and communication. We draw from cross-disciplinary conversations to identify four facets of “good” STEM writing: (1) connecting to the big …

Momentum, Rather Than Velocity, Is A More Effective Measure Of Improvements In Division Ia Football Player Performance, J. Bryan Mann, Jerry L. Mayhew, Marcel Lopes Dos Santos, J. Jay Dawes, Joseph F. Signorile

Faculty Publications - Kinesiology and Recreation

Speed, or the time to complete straight runs or agility drills, is commonly used to assess performance in collegiate American football players. However, it is common for players' speeds to plateau by the second year of eligibility, whereas their body masses continue to increase. The purpose of this study was to track change in speed, body mass, and momentum (body mass · velocity), across Division 1 football players' 4-year careers (n = 512). Complete data were derived for the 40-yd sprint (n = 82), the proagility shuttle (n = 73), and the L drill (n = 73) from the same …

Removal Of Emerging Contaminants From Wastewater Streams Using Membrane Bioreactors: A Review, Arijit Sengupta, Mahmood Jebur, Mohanad Kamaz, Sumith R. Wickramasinghe

Chemical Engineering Faculty Publications and Presentations

Water is a very valuable natural resource. As the demand for water increases the presence of emerging contaminants in wastewater has become a growing concern. This is particularly true when one considers direct reuse of wastewater. Obtaining sufficient removal of emerging contaminants will require determining the level of removal for the various unit operations in the wastewater treatment process. Membrane bioreactors are attractive as they combine an activated sludge process with a membrane separation step. They are frequently used in a wastewater treatment process and can operate at higher solid loadings than conventional activated sludge processes. Determining the level of …

The Effects Of Running Durations On Executive Function, Lauren Bainter

Honors Baccalaureate Theses

The purpose of this study was to examine the relationship between running habits and specific executive functions. Three cognitive function tests were administered virtually to men and women ages 18 – 61 through a validated web-based application (PsyToolKit) and were preceded by a demographic questionnaire. A total of 199 participants were analyzed. The cognitive functions assessed were cognitive inhibition by the Stroop Color and Word Test, visuospatial short-term working memory by the Corsi block-tapping test, and working memory capacity by the 2-back task. A linear regression was used to determine relationships between running and cognitive function. Significant correlations were found …

Root Phenotyping Of Peptide-Treated Glycine Max, Salem Jackson, Fiona Goggin

Inquiry: The University of Arkansas Undergraduate Research Journal

Plant elicitor peptides (Peps) – endogenous chains of amino acids involved in natural plant defense – have been shown to decrease damage from herbivores and pathogens by inducing an immune response, increasing the emission of volatile organic compounds (VOCS), transcripts, and metabolites. Exogenous treatment of soybean seeds with plant elicitor peptide GmPep3 has been shown to induce these broad-spectrum defenses and offers a new method for increasing crop yield. However, the effects of GmPep3 on indicators of soybean health – root characteristics, growth stages, etc. – have not been fully realized. Using the root-phenotyping platform RhizoVision Explorer, several root traits …

Impact Of Single-Family-Room Nicu Design On Infant Neurodevelopment And Breast Milk Provision, Lucille Kohlenberg

Yale Medicine Thesis Digital Library

NEONATAL INTENSIVE CARE UNIT DESIGN IMPACTING INFANT OUTCOMES AND BREAST MILK PROVISION.

Lucille Kohlenberg and Angela Montgomery, MD, MSEd. Section of Neonatal-Perinatal Medicine, Department of Pediatrics, Yale School of Medicine. New Haven, CT.

Single-family room (SFR) NICUs have gradually replaced open-bay (OB) units over the last three decades. Compared to OB units, SFR units provide increased opportunities for parental rooming and maternal breast milk (MBM) provision; however, they may also present fewer sensory exposures and parental learning opportunities. Due to the presence of potentially beneficial and detrimental effects, it remains uncertain whether the SFR design offers aggregate advantages over the …

Prenatal Perception Of Wic Breastfeeding Recommendation Predicts Breastfeeding Outcomes In Infant's First Year, Joanne Guthrie, Qi Zhang, Kelin Li, Kathryn Wouk, Rajan Lamichhane

Community & Environmental Health Faculty Publications

Objectives

Promoting breastfeeding (BF) is a priority of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Prior research found that pregnant mothers who believed WIC recommends BF only (versus BF and formula equally OK) were more likely to initiate BF and continue through 1 month postpartum. We examine whether such mothers are more likely to continue to exclusively BF through 5 months and BF at all through the infant's first year. Methods

Data are from the WIC Infant and Toddler Feeding Practices Study-2 (ITFPS-2), a longitudinal study that includes 2,649 mothers who completed prenatal interviews. Four BF …
