Foster Parents' Perceptions And Beliefs About Social Emotional Development In Infants And Toddlers, Susan R. Noel

DNP Projects

Infants and toddlers placed in foster care are at increased risk for social-emotional (SE) development dysregulation. Foster parents, as surrogate parents, play a critical role in a young child having the potential for healthy SE development. The transactional model supports the complex and intricate interplays and transactions of the child, the foster parent, and the environment that influences a healthy SE development. This qualitative descriptive study explored foster parent knowledge, behavioral cue recognitions, and role perception regarding a young child's SE development. Although the sample size was small, the study provides relevant information, from the on-going experiences of foster parents, …

Conservation Agriculture In Kentucky: Investigating Nitrogen Loss And Dynamics In Corn Systems Following Wheat And Hairy Vetch Cover Crops, Rebecca Erin Shelton

Theses and Dissertations--Plant and Soil Sciences

Unintentional nitrogen (N) loss from agroecosystems produces greenhouse gases, induces eutrophication, and is costly for farmers; therefore, adoption of conservation agricultural management practices, such as no-till and cover cropping, has increased. This study assessed N loss via leaching, NH₃ volatilization, N₂O emissions, and N retention in plant and soil pools of corn conservation agroecosystems across a year. Three systems were evaluated: 1) an unfertilized organic system with cover crops Vicia villosa, Triticum aestivum, or a mix of the two; 2) an organic system with a Vicia cover crop employing three fertilization schemes (0 N, organic N, …

Soil Management And Nitrogen Dynamics In Burley Tobacco Rotations, Congming Zou

Theses and Dissertations--Plant and Soil Sciences

Agronomic practices, including tillage, crop rotation and N fertilization, have been developed to efficiently manage soil N dynamics and crop N nutrition. These practices can affect soil organic carbon (SOC) and soil total nitrogen (STN) sequestration, and consequently influence soil nitrogen mineralization (SNM) and crop N nutrition. However, little research has been systematically and simultaneously conducted to examine the effect of agronomic management on (1) SOC and STN stocks; (2) SNM; and (3) crop N nutrition. Burley tobacco (Nicotiana tobacum L.) is a N demanding crop and subject to inefficiency in N fertilization. Moreover, conservation tillage and rotation have been …

Unveiling Novel Aspects Of D-Amino Acid Metabolism In The Model Bacterium Pseudomonas Putida Kt2440, Atanas D. Radkov

Theses and Dissertations--Plant and Soil Sciences

D-amino acids (D-AAs) are the α-carbon enantiomers of L-amino acids (L- AAs), the building blocks of proteins in known organisms. It was largely believed that D-AAs are unnatural and must be toxic to most organisms, as they would compete with the L-counterparts for protein synthesis. Recently, new methods have been developed that allow scientists to chromatographically separate the two AA stereoisomers. Since that time, it has been discovered that D-AAs are vital molecules and they have been detected in many organisms. The work of this dissertation focuses on their place in bacterial metabolism. This specific area was selected due to …

Urea Formulations On The Productivity Of Bermudagrass And Bermudagrass-White Clover Pastures, Caitlin Timberlake

Theses and Dissertations--Plant and Soil Sciences

Bermudagrass (Cynodon dactylon L.) is a perennial warm-season grass that is very responsive to nitrogen (N) fertilization. Excessive N applications have negative environmental consequences and make maintaining mixed swards difficult. This study determined the effects of enhanced efficiency (EE) N fertilizers and fertilizer rate on bermudagrass yields, nutritive values, and white clover persistence. Nitrogen sources included urea, urea formulated with Agrotain^® (U+A), urea with Agrotain^® and dicyandiamide (SuperU), a polymer-coated urea (ESN), ESN+urea (75% ESN, 25% urea), and methylene urea (MU). In the urea formulation trial, SuperU and U+A maximized forage yields at lower N rates. The …

Characterization Of Co-Circulating Swine Influenza A Viruses In North America And The Identification Of A Novel H1 Genetic Clade With Antigenic Significance, Tavis K. Anderson, Brian A. Campbell, Martha I. Nelson, Nicola S. Lewis, Alicia Janas Martindale, Mary Lea Killian, Amy L. Vincent

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Multiple genetically and antigenically distinct hemagglutinin genes of the H1 and H3 influenza A virus (IAV) subtypes co-circulate in North American swine. This diversity has evolved by repeated transmission of IAVs from humans to swine and subsequent antigenic drift in swine. To understand the evolutionary dynamics of these diverse HA lineages in North American swine, we undertook a phylogenetic analysis of 1576 H1 and 607 H3 HA gene segments, as well as 834 N1 and 1293 N2 NA gene segments, and 2126 M gene segments. These data revealed yearly co-circulation of H1N1, H1N2, and H3N2 viruses, with three HA clades …

Effect Of Turning Frequency And Season On Composting Materials From Swine High-Rise Facilities, K L. Cook, E L. Ritchey, J H. Loughrin, M Haley, K R. Sistani, C H. Bolster

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Composting swine slurries has several advantages, liquid slurries are converted to solids at lower moisture, the total volume and weight of material is reduced and the stabilized product is more easily transported off-site. Despite this, swine waste is generally stored, treated and applied in its liquid form. High-rise finishing facilities (HRFF) permit liquid slurries to be converted to solids which are partially decomposed underneath the HRFF and then finished in compost windrows. The purpose of this study was to evaluate the effect of turning frequency and ambient weather conditions on biological, physical and chemical properties of composted slurry-woodchip mixtures from …

Antimicrobial-Resistant Bacterial Populations And Antimicrobial Resistance Genes Obtained From Environments Impacted By Livestock And Municipal Waste, Getahun E. Agga, Terrance M. Arthur, Lisa M. Durso, Dayna M. Harhay, John W. Schmidt

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

This study compared the populations of antimicrobial-resistant bacteria and the repertoire of antimicrobial resistance genes in four environments: effluent of three municipal wastewater treatment facilities, three cattle feedlot runoff catchment ponds, three swine waste lagoons, and two “low impact” environments (an urban lake and a relict prairie). Multiple liquid and solid samples were collected from each environment. The prevalences and concentrations of antimicrobial-resistant (AMR) Gram-negative (Escherichia coli and Salmonella enterica) and Gram-positive (enterococci) bacteria were determined from individual samples (n = 174). The prevalences of 84 antimicrobial resistance genes in metagenomic DNA isolated from samples pooled (n = …

Characterization Of Novel Brown Midrib 6 Mutations Affecting Lignin Biosynthesis In Sorghum, Erin D. Scully, Tammy Gries, Deanna L. Funnell-Harris, Zhanguo Xin, Frank A. Kovacs, Wilfred Vermerris, Scott E. Sattler

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The presence of lignin reduces the quality of lignocellulosic biomass for forage materials and feedstock for biofuels. In C4 grasses, the brown midrib phenotype has been linked to mutations to genes in the monolignol biosynthesis pathway. For example, the Bmr6 gene in sorghum (Sorghum bicolor) has been previously shown to encode cinnamyl alcohol dehydrogenase (CAD), which catalyzes the final step of the monolignol biosynthesis pathway. Mutations in this gene have been shown to reduce the abundance of lignin, enhance digestibility, and improve saccharification efficiencies and ethanol yields. Nine sorghum lines harboring five different bmr6 alleles were identified in …

Acute Cocaine Differentially Induces Pka Phosphorylation Substrates In Male And Female Rats, Wei-Lun Sun, Luyi Zhou, Arbi Nazarian, Vanya Quinones-Jenab, Shirzad Jenab

Publications and Research

Background: Sex differences in intracellular dopamine pathways may contribute to the known sex differences in psychomotor responses to cocaine and differential development of dependence. This study aimed to determine whether there are sex differences in the activation of the extracellular signal-regulated kinases (ERK1/2, or p44/p42 MAPK) and PKA phosphorylation-dependent substrates in the nucleus accumbens (NAcc) of male and female rats at baseline or after acute cocaine administration.

Methods: 60-day-old male and female Fischer rats were injected with saline or cocaine (30 mg/kg) and sacrificed 5, 15, 30, 45 or 90 minutes later. Total locomotor activity, Stereotypic, rearing, and ambulatory behaviors …

How Polymorphic Warnings Reduce Habituation In The Brain—Insights From An Fmri Study, Bonnie Brinton Anderson, C. Brock Kirwan, Jeffrey L. Jenkins, David Eargle, Seth Howard, Anthony Vance

Faculty Publications

Research on security warnings consistently points to habituation as a key reason why users ignore security warnings. However, because habituation as a mental state is difficult to observe, previous research has examined habituation indirectly by observing its influence on security behaviors. This study addresses this gap by using functional magnetic resonance imaging (fMRI) to open the “black box” of the brain to observe habituation as it develops in response to security warnings. Our results show a dramatic drop in the visual processing centers of the brain after only the second exposure to a warning, with further decreases with subsequent exposures. …

Applying Wetland Rating Systems To Assess Functions Of Depressional Wetlands Created By A Mass Wasting Feature, Table Mountain, Washington, Thomas S. Wachholder

All Master's Theses

The formation of wetlands in the Swauk Watershed has been primarily controlled by mass wasting events, which includes landslide activity. Landslide activity has been the primary influential process in shaping the landscape where wetland systems have formed on the surface of landslide deposits. The wetland sites used in this study, near the base of Table Mountain, were chosen because they inhabit the same ancient landslide, have the same underlying geology, and vary in aspect and elevation. The elevational gradient of the sites ranges from 1300 – 1600 m and the individual wetlands differ in terms of north- and south-facing aspects. …

A Zooarchaeological Analysis Of The Monashka Bay Site (Kod-026) Kodiak Island, Alaska, Ayla Aymond

All Master's Theses

This thesis involved the initial analysis of fauna recovered in 1989 by Christopher Donta at the Monashka Bay site on Kodiak Island. Analysis included all vertebrate remains (n = 36,273) larger than 1/8” from bulk samples collected in Area 3, a midden dating AD 1550-1670 during the site’s Koniag occupation. Results indicated a focus on cod (68% of fish identified to order), with modest amounts of sculpin, and small amounts of flatfish, salmon, herring, bird, and sea mammal. The predominance of cod is likewise seen at other Koniag-era sites in the vicinity, though the lack of salmon, which composed 2% …

Exercise Motivations Of Older Adults, Laura J. Attaway

All Master's Theses

This study examined and compared activity levels and motives in 103 older (over 50 years of age) competitive athletes (CA) and non-competitive fitness exercisers (NCF). The findings indicate that the CA group was significantly higher in the motives of enjoyment, competition, and social recognition. Ranking of the strength of the motivation factors for each group indicated that enjoyment was the strongest motivating factor for both groups, health ranked high for both groups, and social recognition ranked lowest in both groups. Findings related to rankings were not tested for significance, so are more tentative.

Underwater Sound Transmission Through Arrays Of Disk Cavities In A Soft Elastic Medium, David C. Calvo, Abel L. Thangawng, Christopher N. Layman Jr., Riccardo Casalini, Shadi F. Othman

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Scattering from a cavity in a soft elastic medium, such as silicone rubber, resembles scattering from an underwater bubble in that low-frequency monopole resonance is obtainable in both cases. Arrays of cavities can therefore be used to reduce underwater sound transmission using thin layers and low void fractions. This article examines the role of cavity shape by microfabricating arrays of disk-shaped air cavities into single and multiple layers of polydimethylsiloxane. Comparison is made with the case of equivalent volume cylinders which approximate spheres. Measurements of ultrasonic underwater sound transmission are compared with finite element modeling predictions. The disks provide a …

Do Olfactory Stimuli Increase Presence During Exposure Tasks: A Comparative Study, Benson Munyan

Electronic Theses and Dissertations

Exposure therapy (ET) is an extensively studied and supported treatment for anxiety and trauma-related disorders. ET works by exposing the patient to the feared object or situation without any danger in order to overcome the related anxiety. Over the past few years, various technologies including head-mounted displays (HMDs), scent machines, and headphones have been used to augment the exposure therapy process by presenting multi-sensory cues (e.g., sights, smells, sounds) to increase the patient*s sense of presence. While studies have shown that scents can elicit emotionally charged memories, no prior research could be identified that examined the effect of olfactory stimuli …

The Effect Of Traumatic Brain Injury On Exposure Therapy In Veterans With Combat-Related Posttraumatic Stress Disorder, Kathleen Ragsdale

Electronic Theses and Dissertations

Veterans of Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn are presenting for treatment with high rates of combat-related posttraumatic stress disorder (PTSD) and traumatic brain injury (TBI), spurring a need for clinical research on optimal treatment strategies. While exposure therapy has long been supported as an efficacious treatment for combat-related PTSD, some clinicians are hesitant to utilize this treatment for veterans with TBI history due to presumed cognitive deficits that may preclude successful engagement. The purpose of this study was to compare exposure therapy process variables in veterans with PTSD only and veterans with PTSD+TBI. Results suggest …

Applying The Cacao Change Model To Promote Systemic Transformation In Stem, Anthony Marker, Patricia Pyke, Sarah Ritter, Karen Viskupic, Amy Moll, R. Eric Landrum, Tony Roark, Susan Shadle

Organizational Performance and Workplace Learning Faculty Publications and Presentations

Since its inception in the Middle Ages, the university classroom can be characterized by students gathered around a sage who imparts his or her knowledge. However, the effective classroom of today looks vastly different: First-year engineering students not only learn basic engineering principles, but are also guided to consider their own inner values and motivations as they design and build adaptive devices for people with disabilities; students in a large chemistry lecture work animatedly together in small groups on inquiry-based activities while an instructor and teaching assistants circulate and guide their learning; students learning differential equations practice explicit metacognitive skills …

Long Live The Evil Queen: Once Upon A Time's Evolved Villain, Frank S. Lombari

Pell Scholars and Senior Theses

Mirror on the wall, who's the fairest Queen of all? In today's pop culture, many traditional villains are beginning to be turned into antiheroes. ABC's television show Once Upon a Time has taken a number of fairy tale villains and provided them both a background and character growth. Specifically, the adaptation of the Evil Queen has shifted from primary antagonist to redeemed hero over the first three seasons. The show also displays her in the real-world rather than just a fairy tale universe. The author claims that this radical development occurs due three essential aspects: the Evil Queen and Snow …
