Life Events, Initial Sexual Behaviors, And Teenage Pregnancy Among African American Females, Yonzetta Brook Tillman

Walden Dissertations and Doctoral Studies

Teenage pregnancy is disproportionate between African American and Caucasian females. This disproportion is notable because African American teenagers are 3 times more likely to become pregnant than their Caucasian counterparts are. The purpose of this study was to determine whether a relationship exists among major life events, sexual behaviors, and resultant teenage pregnancy among African American females in the United States. The theoretical framework for this study was social learning theory. Three key research questions focused on relationships among (a) major life events and initial sexual behavior, (b) ethnicity, and (c) teenage pregnancy. Independent variables were life event and ethnicity, …

Unearthing The Process Roots Of Environment Ethics: Whitehead, Leopold, And The Land Ethic, Brian G. Henning

Philosophy Faculty Scholarship

The aim of this essay is twofold. First, I examine the role of Alfred North Whitehead and process thinkers in bringing about and shaping the field of environmental ethics. As we will see, our job is not so much to develop the connections between Whitehead and environmental thought as to recover them. Second, given this genealogical work, I invite process scholars to reconsider their generally hostile reception of Aldo Leopold and his land ethic. I suggest that a version of the land ethic grounded in a process axiology could make a significant contribution to contemporary environmental thought.

Weighing The Relative Potential Impacts Of Climate Change And Land-Use Change On An Endangered Bird, Betsy A. Bancroft, Joshua J. Lawler, Nathan H. Schumaker

Biology Faculty Scholarship

Climate change and land-use change are projected to be the two greatest drivers of biodiversity loss over the coming century. Land-use change has resulted in extensive habitat loss for many species. Likewise, climate change has affected many species resulting in range shifts, changes in phenology, and altered interactions. We used a spatially explicit, individual-based model to explore the effects of land-use change and climate change on a population of the endangered Red-cockaded Woodpecker (RCW; Picoides borealis). We modeled the effects of land-use change using multiple scenarios representing different spatial arrangements of new training areas for troops across Fort Benning. …

Use Of High-Fidelity Simulation Training For New Cardiothoracic Intensive Care Unit Nurses, Bryan Boling

DNP Projects

Critical care nursing is one of the most challenging, high-stress fields in healthcare. This is especially true for nurses in the highly specialized environment of the cardiothoracic intensive care unit (CTICU). The experience level of nurses in critical care is positively linked with patient outcomes; however, with older nurses retiring or moving away from the bedside and younger nurses increasingly moving into advanced practice or management and leadership roles it is becoming more difficult to maintain a high degree of nursing experience in the ICU. Simulation training has been used to provide safe, effective training, and it is even possible …

Preventing Delirium Through The Implementation Of The Abcde Bundle And Pad Guideline Into Everyday Care In A Community Hospital Intensive Care Unit: Opportunities For Practice Improvement, Mary Zody

DNP Projects

This DNP project focuses on the reduction of delirium through improvement of nursing knowledge of delirium and implementation of evidence based bundle ( Awake, Breathing, Coordination, Early Mobility, and Pain, Agitation, Delirium) into a twelve bed intensive care unit located in a 150 bed community hospital. Specifically, this project will review the literature supporting the evidence based bundle and report on a comprehensive gap analysis which was done to determine areas for practice improvement to reduce delirium and improve patient outcomes. The gap analysis included a comparison of current practice to the evidence, a review of administrative policies/ statements of …

Polyphenol Content And Differential Expression Of Flavonoid Biosynthetic Pathway Genes Of Fragaria Spp. With White Fruit, Sutapa Roy

Theses and Dissertations--Plant and Soil Sciences

Strawberries are a rich source of polyphenols which contribute to berry color and plant disease resistance, and have been shown to lower the risk of many chronic when consumed. While a considerable body of work exists on the polyphenolic composition of commercial strawberry (Fragaria x ananassa Duch.), less information is available concerning polyphenols in Fragaria vesca, or Alpine strawberry, considered a model system for the Rosaceae family of crop species. The study of natural and genetically-engineered F. vesca mutants with white fruit can provide unique insight into regulation of metabolic flux through the complex branched phenylpropanoid/flavonoid biosynthetic pathway. …

Studies On Regulation Of Pqq-Dependent Phosphate Solubilization Among Rhizosphere Dwelling Bacteria, Ran An

Theses and Dissertations--Plant and Soil Sciences

Plant growth promotion can be enhanced by soil- and rhizosphere-dwelling bacteria by a several different methods. One method is by promoting nutrient acquisition from soil. Phosphorus is an essential nutrient that plants obtain from soil, but in many cases it is immobilized in forms that are not available for plant uptake. Bacteria can solubilize insoluble soil phosphates by secreting gluconic acid. This chemical is produced from glucose by the activity of the bacterial enzyme glucose dehydrogenase, which requires a coenzyme called PQQ. In this dissertation, I studied the regulation of the glucose dehydrogenase enzyme and the PQQ coenzyme in the …

Transcriptional Regulation Of Specialized Metabolites In Arabidopsis Thaliana And Catharanthus Roseus, Craig M. Schluttenhofer

Theses and Dissertations--Plant and Soil Sciences

For millennia humans have utilized plant specialized metabolites for health benefits, fragrances, poisons, spices, and medicine. Valued metabolites are often produced in small quantities and may command high prices. Understanding when and how the plant synthesizes these compounds is important for improving their production. Phytohormone signaling cascades, such as jasmonate (JA) activate or repress transcription factors (TF) controlling expression of metabolite biosynthetic genes. TFs regulating specialized metabolite biosynthetic genes can be manipulated to engineer plants with increased metabolite production.

WRKY transcription factor are known components of both JA signaling cascades and regulation of specialized metabolism. The presence of WRKY binding …

The Effects Of Manufactured Nanomaterial Transformations On Bioavailability, Toxicity And Transcriptomic Responses Of Caenorhabditis Elegans, Daniel L. Starnes

Theses and Dissertations--Plant and Soil Sciences

In recent decades, there has been a rapid expansion in the use of manufactured nanoparticles (MNPs). Experimental evidence and material flow models predict that MNPs enter wastewater treatment plants and partition to sewage sludge and majority of that sludge is land applied as biosolids. During wastewater treatment and after land application, MNPs undergo biogeochemical transformations (aging). The primary transformation process for silver MNPs (Ag-MNPs) is sulfidation, while zinc oxide MNPs (ZnO-MNPs) most likely undergo phosphatation and sulfidation. Our overall goal was to assess bioavailability and toxicogenomic impacts of both pristine, defined as-synthesized, and aged Ag- and ZnO-MNPs, as well as …

Death Row, Calls For Indifference, And Redemption Of The Soul, Corinna Barrett Lain

Law Faculty Publications

In this Response, I first engage with McLeod’s article, summarizing its key claims and endorsing its call for legislative action, while disagreeing at times with the analytical moves it makes along the way. I then turn to two questions that the article inspired. One stems from comments in the constitutional, academic, and public discourse calling for indifference to the way we treat the condemned in light of the way they treated their victims. Given the depravity of the crimes the condemned have committed, why should we care about the conditions under which they are housed on death row? The other …

Copyright In Pantomime, Brian L. Frye

Cardozo Arts & Entertainment Law Journal

Why does the Copyright Act specifically provide for the protection of "pantomimes"? This Article shows that the Copyright Act of 1976 amended the subject matter of copyright to include pantomimes simply in order to conform it to the Berne Convention for the Protection of Literary and Artistic Works. It further shows that the Berlin Act of 1909 amended the Berne Convention to provide for copyright protection of "les pantomimes" and "entertainments in dumb show" in order to ensure copyright protection of silent motion pictures. Unfortunately, the original purpose of providing copyright protection to '"pantomimes " was forgotten. This Article argues …

Estrogen Signaling And Endocrine Disruption Potential In The Embryonic Development Of The Female Reproductive Tract Of The American Alligator, Alligator Mississippiensis, Brenna M. Doheny

MUSC Theses and Dissertations

Perturbation of endocrine signaling during critical embryonic developmental windows has been implicated in many female reproductive system disorders. Reproductive tract anomalies in women exposed in utero to synthetic estrogen diethylstilbestrol, prescribed as a miscarriage preventative, provided some of the first evidence for this “embryonic origins of adult disease” paradigm and suggested a role for estrogen signaling in female reproductive tract (FRT) differentiation. Developmental studies of FRT in other vertebrates have great value in furthering our understanding of embryonic origins of reproductive disorders. The alligator is a particularly intriguing model as an environmental sentinel species with temperature dependent sex determination, which …

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

NE Trailblazer C-1 (GP-101, PI 672015), NE Trailblazer C0 (GP-100, PI 672014), NE Trailblazer C2 (GP-102, PI 672016), NE Trailblazer C3 (GP-103, PI 672017), NE Trailblazer C4 (GP-104, PI 672018), and NE Trailblazer C5 (GP-105, PI 672019) switchgrass (Panicum virgatum L.) germplasms were released by the USDA-ARS and the University of Nebraska-Lincoln on 10 Sept. 2014. These germplasms were developed by six generations of divergent breeding for in vitro dry matter digestibility (IVDMD). As a result of the multigenerations of recurrent breeding, the resulting populations differ significantly for IVDMD and for 25 other forage quality or biomass composition traits, …

Phenotype And Function Of Cd209+ Bovine Blood Dendritic Cells, Monocyte-Derived- Dendritic Cells And Monocyte-Derived Macrophages, Kun Taek Park, Mahmoud M. Elnaggar, Gaber S. Abdellrazeq, J. P. Bannantine, Victoria Mack, Lindsay M. Fry, William C. Davis

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

Phylogenic comparisons of the mononuclear phagocyte system (MPS) of humans and mice demonstrate phenotypic divergence of dendritic cell (DC) subsets that play similar roles in innate and adaptive immunity. Although differing in phenotype, DC can be classified into four groups according to ontogeny and function: conventional DC (cDC1 and cDC2), plasmacytoid DC (pDC), and monocyte derived DC (MoDC). DC of Artiodactyla (pigs and ruminants) can also be sub-classified using this system, allowing direct functional and phenotypic comparison of MoDC and other DC subsets trafficking in blood (bDC). Because of the high volume of blood collections required to study DC, cattle …

Evolution And Biogeography Of Haemonchus Contortus: Linking Faunal Dynamics In Space And Time, Eric P. Hoberg, D.S. Zarlenga

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

History is the foundation that informs about the nuances of faunal assembly that are essential in understanding the dynamic nature of the host-parasite interface. All of our knowledge begins and ends with evolution, ecology and biogeography, as these interacting facets determine the history of biodiverse systems. These components, relating to Haemonchus, can inform about the complex history of geographical distribution, host association and the intricacies of host-parasite associations that are played out in physiological and behavioural processes that influence the potential for disease and our capacity for effective control in a rapidly changing world. Origins and evolutionary diversification among species …

Standardization Of Rp-Hplc Methods For The Detection Of The Major Peanut Allergens Ara H 1, Ara H 2 And Ara H 3, Harmit Singh, Mary Jo Cantoria, Poonam Malave, Denny Saputra, Soheila Maleki

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

Crude peanut extract (CPE) was analyzed for three major allergens (Ara h 1, h 2, and h 3) using a C₁₂ and a C₁₈ column at two wavelengths (280 and 220 nm) and under different solvent conditions. HPLC profiles were compared for retention time, resolution, and peak heights. CPE samples were spiked with pure allergens to identify the peaks corresponding to allergens. The HPLC fractions of corresponding allergens were collected and freeze-dried in order to perform SDS–PAGE and immunoblotting tests. The best method was identified the one with a shorter retention time, better resolution, and greater peak height …

The Worm’S Eye View Of Community Ecology, Tavis K. Anderson, Michael V. K. Sukhdeo

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

The study of parasites in the context of community level organization, either as parasites embedded within host communities, or as parasite communities themselves, is now quite prevalent in parasitology and ecology today. However, this was not always the case. In terms of publications, there was almost no consideration of parasite interactions at the community level for most of the first half of the last century. Papers in The Journal of Parasitology by Clark Read (1951) and John Holmes (1961) were the defining contributions to the beginning of the field, and the ideas elaborated by these two parasitologists still inspire current …

Writing Life Stories: A Phenomenological Study Of Memory And Meaning For People With Early Stage Alzheimer's Disease, Jennifer E. Dimond Msw

All Student Scholarship

There are an estimated five million Americans living with Alzheimer’s disease; experts believe that by mid-century, that number will more than triple. The disease is the sixth leading case of death in the U.S., and the only one among the top ten with no known cure, treatment or means of prevention. An emerging body of research suggests that providing people with Alzheimer’s opportunities to tell their life stories can help them negotiate their personal identities and may have positive impacts on their sense of self. A hermeneutic phenomenological approach is used to understand the lived experience of people with early …

International Legal Structuralism: A Primer, Justin Deystone

Publications

International legal structuralism arrived on the shores of international thought in the 1980s. The arrival was not well-received, perhaps in part, because it was not well-understood. This essay aims to reintroduce legal structuralism and hopefully pave the way for new, and more positive, receptions and understandings. This reintroduction is organized around two claims regarding the broader encounter between international lawyers and critical theory in the ‘80s. The first was a jurisprudential claim about how the critics sought to show how international law was nothing more than a continuation of international politics by other means. The second was a historical claim …

Rethinking Drinking: A Paradigm Shift For Estimating Social And Behavioral Harm, Thomas Hall

Electronic Theses and Dissertations

This study challenges old saws about negative consequences attributed to alcohol use. Previous research findings associate negative social and behavioral consequences with alcohol consumption, as if college students only do regrettable things when they are drunk. Typical research related to negative consequences and alcohol use relies on retrospective self-reporting. Investigators often frame negative consequences as outcomes of problematic drinking or, as more commonly labeled, "binge drinking." In the nomenclature of prevention, binge drinking is not a direct measure of alcohol use resulting in intoxication; it is a hypothetical tipping point, predicting an increased likelihood of the incidence of negative consequences …

A Tale Of Two Palmettos: The Foundation Of Ecosystems, Warren G. Abrahamson Ii

Faculty Journal Articles

Fruits of saw palmetto (Serenoa repens) provide crucial, high-quality resources to wildlife while providing a matrix for many southeastern US ecosystems. As a foundation species, saw palmetto plays a major role in structuring fire-maintained plant communities. Often living on nutrient-poor soil conditions, the thick leaves of saw palmetto are long lived, up to 2.8 years in shaded sand pine scrub.

Evidence Of Rock Kangaroo Seed Dispersal Via Faecal Seed Storage In A Tropical Monsoon Community, Chris Martine, Ally Boni, Elizabeth Capaldi, Gemma Lionheart, Ingrid E. Jordon-Thaden

Faculty Journal Articles

While some of the plant species of the ‘Sandstone Country’ along the escarpment of western Arnhem Land produce fleshy fruits and appear to rely on biotic methods of seed dispersal, little is known about the methods by which this is achieved – and few potential dispersers co-occur in the sandstone outcrop communities. For the present study, scat collections were made on outcrops in the northeastern area of Kakadu National Park with the hope of uncovering relationships between local frugivores and fruit-producers, and providing evidence for seasonal storage of mammal-dispersed seeds in scat prior to germination. The goals of the present …

Preparing For The Inevitable: Sensemaking In Parent-Child Discussions Of Death, Carrie Ann Wartmann

Electronic Theses and Dissertations

Death is something everyone will eventually encounter, yet American society has a tendency to avoid or deny death in everyday life and language. Death makes people uncomfortable, and many view it as a topic too complex for children to understand. Children, however, witness big and little deaths in their lives: of pets, relatives, plants, and favorite fairy tale characters. When a child experiences a death, he or she may have questions for parents or other trusted adults which our current avoidance-geared society does not prepare adults for. Children exist in a specific cultural context, and learn rules and expectations of …

Mate Selection Comparisons In Heterosexual And Homosexual Individuals, Daina Lee Wierzbinski

All Master's Theses

The effects of character traits and socioeconomic status on mate selection for both heterosexual and homosexual individuals was studied. The current study recruited 347 Central Washington University students who ranked the importance of descriptive traits in a potential long-term mate, and also reported how willing they were to date a fictional potential mate in both a short-term and long-term context. Participants also described themselves in a dating profile scenario. The findings support the hypothesis that women are more interested in traits that signal resource acquisition and high socioeconomic status, and also support the hypothesis that men are more interested in …

In Search Of Heterotopia: Immersive Experiences In The Museum, Nicolas Crosby

All Master's Theses

Museums everywhere are waging battle to find ways to attract new audience members. In this thesis I draw upon participant observation, interviews, and event planning in order to examine how museums create heterotopic, interactive immersive experiences. I focus on the work of two Seattle-area museums, and a gallery and a museum in Ellensburg. The Entertainment, Music, and Popular Culture museum (EMP), the Nordic Heritage Museum (NHM), and the Museum of Culture and Environment (MCE) developed opportunities for visitors to engage with museum-created heterotopic events. I approach this analysis through a theoretical framework that emphasizes structure and agency. On one hand, …
