Combining Forage And Cover Crop Benefits From Cool-Season Annuals In The Southeastern United States, Dustin John Smith Jan 2016

Combining Forage And Cover Crop Benefits From Cool-Season Annuals In The Southeastern United States, Dustin John Smith

LSU Master's Theses

Cow-calf operations in the southeastern United States (U.S.) are based on warm-season perennial grass pastures. Stored forage feeding during the non-grazing season constitutes more than half of a cattle operation’s annual expenses. Cool-season annuals can extend the grazing season, thereby reducing stored forage feeding. A two-year field trial was conducted to determine the forage potential of a variety of crops commonly used as winter cover crops in the southeastern U.S. The ten cover crop treatments included seven monocultures (annual ryegrass [Lolium multiflorum], rye [Secale cereal], oats [Avena sativa], triticale [Triticale hexaploide], tillage radish [Raphanus sativus], hairy vetch [Vicia villosa], crimson …

Tests Of Reproductive Isolation Between The Fishes Fundulus Heteroclitus And F. Grandis, Ruthie E. Barbas Jan 2016

Tests Of Reproductive Isolation Between The Fishes Fundulus Heteroclitus And F. Grandis, Ruthie E. Barbas

UNF Graduate Theses and Dissertations

The closely related killifishes Fundulus heteroclitus and F. grandis hybridize in a small region where their ranges overlap in coastal northeastern Florida. Hybrids of these species are rare in frequency within the contact zone, suggesting the presence of relatively strong reproductive isolation between these species. The objective of this study was to elucidate barriers to reproduction between F. heteroclitus and F. grandis in the lab, as well as to quantify the relative strengths and contributions of various isolating barriers. Pre-zygotic (mating and fertilization) and post-zygotic (hatching) barriers were investigated by performing a variety of choice and no-choice laboratory mating experiments. …

Functional Characterization Of A Novel Disaccharide Membrane Transporter In The Digestive Tract Of The American Lobster, Homarus Americanus, Olivia Scheffler Jan 2016

Functional Characterization Of A Novel Disaccharide Membrane Transporter In The Digestive Tract Of The American Lobster, Homarus Americanus, Olivia Scheffler

UNF Graduate Theses and Dissertations

In animals, the accepted model of carbohydrate digestion and absorption involves reduction of disaccharides into the simple sugars glucose, fructose and galactose. Previous studies have shown the presence of disaccharides maltose and trehalose in the blood of several crab species, the crayfish and the American lobster. In 2011, a gene for a distinct disaccharide sucrose transporter (SCRT) was first found in Drosophila melanogaster and characterized using a yeast expression system. The purpose of the current study was to identify and characterize a putative disaccharide transporter analog in crustaceans using the American lobster, Homarus americanus. Brush border membrane vesicles purified …

Structure And Function Of Male Bottlenose Dolphin Alliances In Northeast Florida, Kristin A. Karle Jan 2016

Structure And Function Of Male Bottlenose Dolphin Alliances In Northeast Florida, Kristin A. Karle

UNF Graduate Theses and Dissertations

Bottlenose dolphins exhibit fission-fusion social systems in which group size and composition change fluidly throughout the day. Societies are typically sexually segregated, and the quality and patterning of individual relationships in this social species shape the social structure of a population. Female dolphins usually have a large network of associates with whom they form recurring moderate bonds, while male associations are highly variable due to their mating strategies. Males employ one of two strategies; males may be solitary, and encounter and herd females individually, while others may form strong bonds with one to two other males and cooperatively herd individual …

The Post-Secondary School-To-Work Transitional Program: An Occupational Therapist's Guide To Service Delivery, Annemarie Assel, Erin Haugen

Occupational Therapy Capstones

Background: Autism Spectrum Disorders (ASDs) are one of the most prevalent childhood diagnoses, occurring in every 1 in 68 children (Centers for Disease Control and Prevention, 2015). Although ASDs are considered childhood disorders, they persist throughout one’s life and are often more pronounced during common life transitions. For adults with ASDs, this is a time marked by fragmented services, as well as disengagement from services (Baldwin, Costley, & Warren, 2014; Friedman, Warfield, & Parish, 2013; Shattuck, Wagner, Narendorg, Sterzing, & Hensley, 2011; Strickland, Coles, & Southern, 2013). Those with ASDs have skills deemed valuable by employers that include being: reliable, …

Variation In The Amphibian Hypothalamic Pituitary Adrenal Axis: Patterns, Mechanisms, And Implications, Jessica Thomas Jan 2016

Variation In The Amphibian Hypothalamic Pituitary Adrenal Axis: Patterns, Mechanisms, And Implications, Jessica Thomas

Electronic Theses and Dissertations

Many vertebrate stress responses are mediated by the hypothalamic-pituitary-adrenal/interrenal (HPA/I) axis, which involves hypothalamic secretion of corticotropin releasing factor (CRF) and increased plasma levels of glucocorticoid hormones (GCs) like corticosterone (CORT). Basal HPA/I activity is also imperative to maintaining homeostasis. Despite having crucial roles, HPA/I activity is variable and can be influenced by factors like environment, physiology, and life-history. HPA/I activity also influences reproduction and immunity. To better understand patterns of HPA/I variation (specifically CORT and CRF), we conducted several studies using plethodontid salamanders. Their low-energy lifestyle offers unique contrast to studies of stress physiology in high-energy animals like mammals …

The Social Obligation To Reduce Stigma In Order To Increase Utilization Of Mental Health Services, Melissa Sue Berdell Jan 2016

The Social Obligation To Reduce Stigma In Order To Increase Utilization Of Mental Health Services, Melissa Sue Berdell

Electronic Theses and Dissertations

Many mental health organizations have developed campaigns that concentrate on reducing the stigma towards mental health with the intentions of increasing access and utilization for people with mental illnesses that are not receiving appropriate mental health services. The mental health campaigns predominantly focus on establishing awareness and education related to the number of people with mental illnesses and diagnoses so that people will not be ashamed or embarrassed to have mental illnesses or access mental health treatments. However, societal prejudices have caused many people diagnosed with mental illnesses to lose jobs, homes, and families; therefore, in general, people are afraid …

Truth And Legitimacy (In Courts), Kenneth S. Klein Jan 2016

Truth And Legitimacy (In Courts), Kenneth S. Klein

Faculty Scholarship

This Article draws upon empirical and theoretical scholarship from philosophy, economics, social science, psychology, political science, ethics, and jurisprudence, in addition to more traditional legal sources such as Supreme Court decisions, to develop an articulation of the meaning, role, and importance of truth in courts. It is frequently articulated that trials are a search for truth. But as insiders to the judicial system know, if this is so then it is a meaning of truth that differs what truth means in any other context. And exposing this definitional dissonance in turn exposes that the legitimacy of the courts rests on …

Life-Cycle Cost Analysis Of Nutrient Reduction Technologies Employed In Municipal Wastewater Treatment, Colin Barrett Brown Jan 2016

Life-Cycle Cost Analysis Of Nutrient Reduction Technologies Employed In Municipal Wastewater Treatment, Colin Barrett Brown

Honors Papers

Eutrophication presents a serious threat to America's aquatic ecosystems, negatively impacting both the aquatic life and the communities dependent on these bodies of water. Reducing nutrient inflow of nitrogen and phosphorus into waterways from point and non-point sources is critical in reversing the environmental degradation caused by eutrophication. Municipal wastewater treatment plants are one of the primary point sources of nutrient-rich effluent, and as such, implementing nutrient reduction strategies within the treatment process is an impactful step towards mitigating eutrophication. Grey infrastructure technologies that use mechanical or chemical treatment have historically been used for wastewater nutrient reduction. However, constructed wetlands …

Inverted Quarantine: Individual Response To Collective Fear, Katherine Parker Moncure Jan 2016

Inverted Quarantine: Individual Response To Collective Fear, Katherine Parker Moncure

Honors Papers

In his 2007 book Shopping Our Way to Safety, sociologist Andrew Szasz coined the term inverted quarantine to describe a phenomenon in the way that Americans react to the changing natural environment. Inverted quarantine, or the impulse to remove one’s self from perceived environmental dangers, often manifests in consumption behavior such as consuming only organic food, drinking filtered or bottled water, moving from a city to a suburb, or even being enclosed in a gated community. Although inverted quarantine may result in some form of protection, in the long run it is unsustainable in the face of the changing natural …

Biophilic Architecture, Connectedness To Nature, And The Importance Of Environmental Issues, Sarah Michelle Kahl Jan 2016

Biophilic Architecture, Connectedness To Nature, And The Importance Of Environmental Issues, Sarah Michelle Kahl

Honors Papers

In today’s world where climate change consequences are apparent, we need to be searching for ways to encourage more pro-environmental behaviors. Connectedness to nature, which is the sense of kinship and sense of community with the natural world, is one factor that has been shown to promote pro-environmental behavior. While architecture types have been tested with states of well-being, they have never been assessed to examine the effects on one’s connectedness to nature. This study used Seeley G. Mudd Center (Mudd) and the Adam Joseph Lewis Center (AJLC) at Oberlin College to determine whether biophilic types of architecture versus architecture …

Drawing Dna Sequence Networks, Julia Olivieri Jan 2016

Drawing Dna Sequence Networks, Julia Olivieri

Honors Papers

We explore methods for drawing a graph of DNA sequences on a digital canvas such that the Euclidean distances between sequences on the canvas suggest the distances between the sequences as calculated from pairwise sequence alignment. We use data from three plant taxa, the genus Castilleja as well as the families Caryophyllaceae and Cactaceae, to test our methods. We discuss different possible measures of the cost of a drawing, and analyze heuristic approaches to the problem including random assignment, greedy assignment, the iterated hill-climber, and simulated annealing. We find that our hill-climbing method tends to return superior drawings. Our simulated …

Towards Sustainable Rural Japan: A Case Study On Urban-Rural Migration Motives, Lisa Kanai 16 Jan 2016

Towards Sustainable Rural Japan: A Case Study On Urban-Rural Migration Motives, Lisa Kanai 16

Honor Scholar Theses

With Japan losing its overall population due to low fertility rate, rural depopulation has become a prevalent issue across the country. This thesis examines Oonan Town in Shimane Prefecture as a case study, as it is a rural town that has been successful in getting in-migrants back into the community. Through oral, biographical interviews, participants reported factors that played a significant role in the migration decision-making process. Data show that in-migrants in Oonan Town were largely affected by four factors, which are 1) family ties, 2) life course events, 3) lifestyle preferences, and 4) financial factors. The current study also …

The Question Of Truth In Literature: Die Poetische Auffassung Der Welt, Richard Thomas Eldridge Jan 2016

The Question Of Truth In Literature: Die Poetische Auffassung Der Welt, Richard Thomas Eldridge

Philosophy Faculty Works

This chapter starts with the question of truth in literature, noting that this question has several interrelated senses: can literature present (significant) truths at all?; what does its presentation of truths (if it exists) have to do with its manner of presentation (with literary language)?; and is the presentation of truth a central aim of literary art? The chapter surveys a variety of neo-Fregean (Lamarque and Olsen, Walton) views that reject the very possibility of literary truth as well as a variety of anti-Fregean views (Goodman, Heidegger) that endorse it. But those endorsements often do not say enough about literary …

Changing Winds And Rising Tides On Beach Renourishment In Florida: Short-Term Alternatives And Long-Term Sustainable Solutions Using Law And Policy From Florida And Nearby States, Lewis Van Alstyne Iii

Florida A & M University Law Review

Sandy beaches make up 825 miles of Florida's 1,260 total miles of coastline around the Sunshine State's peninsula. These beaches are changing over time due to the natural erosional forces of wind and water. Coastal engineering attempts to halt natural forces with man-made structures such as buildings, piers, groins, jetties, breakwaters, sea walls, ports, inlets, and in some cases, it creates new sandy beaches and world-class cities where none existed. In an effort to protect the new real estate from the erosion that has always existed, engineers created beach nourishment. This Article focuses on building up beaches through beach nourishment. …

Animal Law And Environmental Law: Exploring The Connections And Synergies, Randall S. Abate, Elizabeth Hallinan, Joan E. Schaffner, Bruce Myers

Journal Publications

Environmental law, with its intricate layers of international, federal, state, and local laws, is more established than its animal counterpart. Yet animal law faces many of the same legal and strategic challenges that environmental law faced in seeking to establish a more secure foothold, both in the United States and abroad. In What Can Animal Law Learn From Environmental Law?, editor Randall S. Abate brought together academics, advocates, and legal professionals to examine the very different histories of environmental and animal law, as well as the legal and policy frameworks that bridge the two fields. On November 16, 2015, the …

Banning Metal Mining In Guatemala, Randall S. Abate, Raquel Aldana Jan 2016

Banning Metal Mining In Guatemala, Randall S. Abate, Raquel Aldana

Journal Publications

Metal mining is unsustainable for Guatemala and its harms insurmountable for its people. Guatemalans who oppose metal mining have been fighting for decades domestically and internationally against the environmental degradation and other human rights abuses from metal mining activities in the country with little to show for their efforts. The State is too weak and corrupt to offer much hope for reform. Guatemala requires extensive governance reforms to become the type of strong democracy capable of reaping the potential benefits of metal mining in its territory. This is a long-term project. Most Guatemalans opposed to metal mining already know this, …

Faculty & Staff Scholarship

Pathogen identification and microbial source tracking (MST) to identify sources of fecal pollution improve evaluation of water quality. They contribute to improved assessment of human health risks and remediation of pollution sources. An MST microarray was used to simultaneously detect genes for multiple pathogens and indicators of fecal pollution in freshwater, marine water, sewage-contaminated freshwater and marine water, and treated wastewater. Dead-end ultrafiltration (DEUF) was used to concentrate organisms from water samples, yielding a recovery efficiency of >95% for Escherichia coli and human polyomavirus. Whole-genome amplification (WGA) increased gene copies from ultrafiltered samples and increased the sensitivity of the microarray. …
