Applicability Of The Dual Isotopes Δ15n And Δ18o To Identify Nitrate In Groundwater Beneath Irrigated Cropland, R. F. Spalding, A. J. Hirsh, M. E. Exner, N. A. Little, K. L. Kloppenborg

Department of Agronomy and Horticulture: Faculty Publications

Identification of the nitrate sources that adversely impact groundwater quality is a necessary first step in the control of this major worldwide pollutant. The impact of nitrate leachate from urea-ammonium nitrate (UAN) (50% urea-N, 25% ammonium-N, 25% nitrate-N) fertilizer, whose use has increased dramatically in the last three decades largely because it can be applied through sprinkler irrigation systems to corn in all growth stages, is investigated. The dual isotopes δ¹⁵N_NO3 and δ¹⁸O_NO3 were measured in groundwater samples from 39 irrigation wells in two intensively sprinkler-irrigated, corn-growing areas of Nebraska with nitrate-contaminated (N …

Cultivation In Long-Term Simulated Microgravity Is Detrimental To Biofilm Formation Ability And Pyocyanin Production Of Pseudomonas Aeruginosa Pa14 Wild Type, Δflgk, And Δpela, Linda M. Vu , '19

Senior Theses, Projects, and Awards

Pseudomonas aeruginosa can attach to surfaces and form aggregates known as biofilms. It has been previously found that P. aeruginosa cultivated in space form thicker and structurally different biofilms than those grown in Earth gravity. The purpose of our study was to investigate how microgravity, simulated in a laboratory setting, would influence the biofilm formation abilities of P. aeruginosa PA14 wild type strain as well as mutants ΔflgK and ΔpelA. While ΔflgK is defective in the initialization of biofilm formation, ΔpelA is hindered in biofilm growth and maintenance. The bacteria were cultivated in a High …

Girl Time: An Enrichment Program Fostering Social And Emotional Well-Being Among Kindergarten Girls, Irene A. Opuka

PCOM Psychology Dissertations

Early identification and intervention are essential in meeting the unique needs of all children and families (Bagdi & Vacca, 2005). In addition to studying the growth of separate emotions and their importance for mature development, researchers have discovered that early-childhood years are a key time for developing capacity to control and regulate emotions (Nuttall, Romero, & Kalesnik, 1999). Schools are designed to promote emotional well-being, and GIRL TIME could be viewed as part of a responsive and collaborative approach to a child-centered service continuum that includes promotion, prevention, and intervention. Effective social-emotional-behavioral interventions have been found to change the balance …

Describing The Impact Of Low Socioeconomic Status On School Performance, Barry Linden Cropp Ii

PCOM Psychology Dissertations

This study used archival school data compiled during the 2017-2018 school year to analyze the impact of family income, as determined by student eligibility for free- or reduced-lunch benefits, on several measures of school performance. This study was based upon an investigation of the effects of income on three dependent variables: academic performance, school attendance, and need for behavioral management interventions. Participants included 165 male students in third through fifth grade who attended a single elementary school in the mid-Atlantic region of the United States. Indicators of school performance were derived from data routinely collected and maintained in students' cumulative …

Sleep, Communicative Ability, And Diet As Predictors Of Aggression In Autism Spectrum Disorder, Rafat Omar

PCOM Psychology Dissertations

Aggression is a common behavioral issue in children with autism spectrum disorder (ASD). Aggression is often treated with evidence-based behavioral treatments, such as applied behavioral analysis and functional communication training. Another form of intervention that has grown in popularity is to alter the child’s diet. The most popular dietary intervention, the autism diet, has been used as a form of behavior management by parents and guardians for children diagnosed with ASD to address aggressive behavior; however, its use has not been strongly supported by research. The authors proposed that a more beneficial way of understanding aggression in ASD is to …

The Relationship Between Cognitive Distortions, Self-Compassion, And Insomnia Severity, Gabriel Stanziano

PCOM Psychology Dissertations

The goal of this study was to examine the relationships between cognitive distortions, self-compassion, and insomnia severity. Individuals were assessed using the Inventory of Cognitive Distortions (ICD), Self-Compassion Scale (SCS), and Insomnia Severity Index (ISI). Data were analyzed using a sample of 67 participants, ranging in age from 18 to 74. A simple linear regression analysis was conducted to test the hypothesis that cognitive distortions would be predictive of insomnia severity. The results were not significant. A multiple regression analysis was used to test the hypothesis that the specific cognitive distortions of fortunetelling, labeling, and jumping to conclusions would be …

Turkish Journal of Biology

In the present study it was aimed to obtain novel strains of actinomycetes that have the ability to promote plant growth. For this, seven soil samples from the rhizosphere of Humulus lupulus (Pazaryeri, Bilecik) were used and potential isolates were obtained. 16S rRNA genes of 30 isolates were amplified by PCR and sequenced. Eighteen isolates were found to be closely related to Streptomycetes spp. and they were tested for their proteolytic activity, cellulase activity, phosphate solubility, IAA production, biofilm formation, and growth in nitrogen-limited medium. Two isolates, HCI 12 and HCI 36, were selected according to the results of these …

Paleoecology Of Northern Great Plains Bison: Inferences From Stable Isotopes And Dental Calculus, Gaimi Lynn Davies

Theses and Dissertations

The purpose of this study is to infer Northern Great Plains bison (Bison bison) paleoecology through the analysis of stable isotopes and dental calculus from bison skeletal remains. Bison used to roam in the millions throughout most of North America but today they are primarily kept in confined and isolated populations. Little is known about their ancestral ecology. The abundance of bison in the archeological record provides a unique opportunity to study their remains on a broad temporal and spatial scale. This research uses the archeological record of bison in North Dakota to study bison diet and environment from the …

Mediation In Medical Treatment: A More Effective Way To Manage Disputes, Caitlin Mcclay

Catholic University Law Review

The right to refuse medical treatment is based on a competent persons due process rights guaranteed by the fifth amendment. Incompetent persons do not have the right to refuse medical treatment. Instead, a process called “substituted judgement” is used to determine what care they will receive. A family member will then make medical decisions on behalf of the incompetent person while they are unable. Disagreements between guardians or between guardians and physicians lead to a court deciding the proper medical treatment.

There two major challenges that arise with the substituted judgement process are that family members often do not know …

Community Risk Factors And Health Inspection Violations In Mississippi Delta Census Tracts, Chrystal S. Early

Walden Dissertations and Doctoral Studies

A concerning public health issue in America is about food deserts urban and rural communities that lack grocery retailers that offer affordable, nutritious, and diverse foods. Empirical evidence has shown significant associations between neighborhood disadvantage/disorder risk factors of high poverty and high percentages of ethnic minority residents with presence/ absence of healthy food retailers in food deserts. The purpose of this quantitative correlational study, framed by the disparities in food safety conceptual model, was to examine if county-level poverty, number of African American residents, number of elderly (i.e., age 65 or older) residents, vehicle ownership, and crime rates were significantly …

Depression Screening In Poststroke, Shannah Lowe

Walden Dissertations and Doctoral Studies

Depression, a sequela of stroke, is underrecognized and underreported. The American Heart/Stroke Association estimated 1/3 of patients develop depression after a stroke. Depression after a stroke has negative influence on stroke recovery through decreased participation in rehabilitation, and increased morbidity and mortality. The American Heart/Stroke Association recommended that depression screening be conducted on stroke patient; however, there is a lack of guidance regarding the optimal time and tools for depression screening. The practice problem identified was the absence of depression screening in poststroke patients at the project site. The project question focused on identifying evidence-based approaches for depression screening in …

On The Efficacy Of Moringa Oleifera As Anticancer Treatment: A Literature Survey, Florentin Smarandache, Victor Christianto

Branch Mathematics and Statistics Faculty and Staff Publications

Medicinal plants are important elements of indigenous medical system that have persisted in developing countries. Many of the botanical chemo-preventions currently used as potent anticancer agents. However, some important anticancer agents are still extracted from plants because they cannot be synthesized chemically on a commercial scale due to their complex structures that often contain several chiral centers. The aim of this study was to test different extracts from the Moringa oleifera leaves. Previous studies have shown potentially antioxidant, antitumor promoter, anticlastogen and anticarcinogen activities both in vitro and in vivo. Emerging evidence indicates that efficacy of Moringa oleifera in cancer …

Athletic Training Student And Student Aide Clinical Task Allowance In The Secondary School Setting, Zachary K. Winkelmann, Robert A. Huggins, Lindsey E. Eberman

Internet Journal of Allied Health Sciences and Practice

Purpose: Athletic training student aides (SA) are minors in high school that participate in an athletic training experience under the supervision of secondary school athletic trainers (SSAT). The NATA published an official statement on the proper supervision of SAs related to task allowance. As SSATs may also supervise athletic training students (ATSs), it is important to understand the differences in both. Therefore, the objective was to explore the training, task allowance, and perspectives of SAs and ATSs by SSATs during clinical experiences. Methods: We used a cross-sectional, web-based survey for this study. SSATs (n=3,567) from the ATLAS database were recruited …

The Correctional Officer-Inmate Relationship: Evaluating Job Functionality To Enhance Rehabilitation, Maya Stern

Faculty Curated Undergraduate Works

The relationship between correctional officers (COs) and the prison populations they survey is vastly understudied in the field of criminal justice. Currently, reports on correctional officers focus on the officers' indispensable role in the prison system as well as their subjectivity to high turnover rates. Studies assessing this relationship would be of great use to prison administrations and the criminal justice system as a whole, because creating effective relationships between COs and inmates may correlate with incidences of job stress and turnover. Utilizing a shift in research would also promote rehabilitative attitudes as the correctional officer and inmate relationship is …

Uncompromising Hunger For Justice: Resistance, Sacrifice, And Latcrit Theory, Brenda Williams, Edwin Lindo, Marc-Tizoc González

Articles

In this Article, three law professors report on and theorize a nonviolent direct-action campaign of the kind discussed by Dr. King in his famous Letter from a Birmingham Jail. Using the basic steps of the nonviolent campaign as an organizing framework, they analyze and report on the 18-day hunger strike by the Frisco 5 (a.k.a., Frisco5). This direct action protested the extrajudicial killings of Amilcar Perez-Lopez, Alex Nieto, Luis Góngora-Pat, and Mario Woods by San Francisco Police Department (SFPD) officers and advocated for institutional change to reduce the risk of homicides against persons with similarly racialized minority-group identities. Two weeks …

Everybody’S Working (But The Weakened): An Assessment Of Medicaid Work Requirements And Their Administrative Burdens, Samuel Misleh

MPA/MPP/MPFM Capstone Projects

Although Medicaid work requirements are currently halted in both Arkansas and Kentucky, this analysis utilizes the data available to make an assessment and estimate of what Kentucky’s Medicaid enrollment will look like if work requirements similar to those Arkansas had are ever implemented. The relative severity of the administrative burden of such requirements provide a tool for comparison, and a difference-in-differences analysis of the change in Medicaid enrollment between Arkansas and West Virginia, a state that has not implemented and currently has no plans to implement Medicaid work requirements, provide the bases for this estimate. After coding the work requirements …

The Role Of Cody In Hydrogen Peroxide Tolerance And Biofilm Formation Of Streptococcus Mutans, Kaitlin M. Rioux, Brandaliz Santiago-Narvaez

Honors Program Theses

Streptococcus mutans is the major cariogenic bacterium in the oral cavity. S. mutans causes disease by three main virulence factors: acid production, acid tolerance, and biofilm formation. S. mutans outcompetes various other species in the oral cavity, however it is affected by hydrogen peroxide production by these species. Based on previous findings and this research, hydrogen peroxide is shown to extend the lag phase of S. mutans but does not kill it unless present in extremely high amounts that are generally not produced by commensal species like S. sanguinis and S. gordonii in the oral cavity. CodY is a global …

The Effect Of Welfare Work Requirements On Tanf Recipients: Individual Employment And Economic Mobility, Destiny Lockhart

Scripps Senior Theses

With many families in poverty in need of assistance in the United States, the government has implemented stricter work requirements to get individuals off welfare and to work. Recipients must now work a state specified number of hours per week to receive aid. Some research suggest that these policies may increase employment rates amongst recipients, yet not lead to their economic growth and independence. This study examines the effect of TANF work requirements on various socioeconomic outcomes for individual recipients, including employment, job quality and income. Data on TANF recipients come from 2014 Survey of Income and Participation. Results suggest …

Reimagining Potential Life: A Socialized Right To Reproductive Freedom, Daniella Henry

Scripps Senior Theses

A more conservative supreme court will likely have the chance to overrule Roe v. Wade. Many states have passed heartbeat laws that will probably be taken all the way to the supreme court, these cases will ask the supreme court to affirm fetal personhood, giving fetuses a constitutionally recognized right to due process and making abortion illegal. In this thesis, I will defend an expansion of protections for pregnant peoples through a socialized right to abortion.

Identification Of Antibiotic Ge37468a From Pseudonocardia Symbionts Of Trachymyrmex Septentrionalis Ants, Krithika Rao

Scripps Senior Theses

In response to the growing rates of antibiotic resistance in human bacterial pathogens, this study explores the natural products involved in the defensive symbiosis between actinobacteria and fungus-growing ants to uncover new potential antibiotics. This study also seeks to understand the function of natural antibiotics in their ecological contexts, especially those involved in defensive symbioses. Defensive symbiosis can be a beneficial platform for discovering useful antibiotics, because antibiotics in these relationships must be able to selectively inhibit enemies without harming hosts, and are therefore likely more specific and less toxic. Pseudonocardia sp. associated with Trachymyrmex septentrionalis ants demonstrated antibiotic activity …

Evidence-Based Probiotic Intervention For Behavioral And Social Deficits In Autism Spectrum Disorder, Allisen To

Scripps Senior Theses

Autism Spectrum Disorder (ASD) refers to a heterogeneous neurological condition characterized by repetitive and restrictive behaviors and social communication deficits. ASD diagnoses are at a record high, at approximately 1 in 59 children according to the US Center for Disease Control. Currently, there are no available interventions that effectively treat the core symptoms of ASD. All pharmaceutical options address comorbid side effects of ASD but not core deficits and are particularly associated with negative side effects. Additionally, there are economic and geographic barriers that can prevent families of individuals with ASD from seeking or receiving effective interventions. Many of the …

Individual Bodies, Informed Consent, And Self-Determination: A Rhetorical Analysis Of The Vaccine Refusal Movement, Gretta Richardson

Scripps Senior Theses

This project sought to explore the narratives and rhetorical themes that permeate the anti-vaccination movement. Mass media has portrayed vaccine refusal groups as stupid, as conspiracy theorists, and as radically selfish. However, the data I analyzed from vaccine refusal nonprofits and advocacy groups supports that although these themes may appear to be radical, in reality, each is congruent with already present societal frameworks, particularly neoliberal social discourse and a preoccupation with the individualistic and self-determined health care rather than utilitarian or collective action.

Written In Bone: Damage Patterns In Agonopsis Vulsa Armor, Morgan Stewart

Scripps Senior Theses

Naturally occurring armor has evolved in many different classes of organisms, often in response to predation, although other factors may play a part. In this study, the scales of the benthic armored fish Agonopsis vulsa were examined for damage patterns in order to illuminate the life history and environmental interactions of the fish. Scales from the fish were systematically destroyed in the lab, and observations made from the damaged scales were used to create a categorical damage rating, which was applied to 34 specimens ranging in trunk length from 2.3 cm to 14.2 cm. The specimens were rendered as three-dimensional …
