Ecosystem Services And Federal Public Lands: A Quiet Revolution In Natural Resources Management, J.B. Ruhl, James Salzman

University of Colorado Law Review

The major federal public land management agencies (the Forest Service, Bureau of Land Management, Park Service, Fish & Wildlife Service, and Department of Defense) have increasingly adopted a language that did not exist twentyfive years ago-the language of ecosystem services. Ecosystem services are the range of benefits that ecological resources provide to humans, from water purification and pollination to carbon sequestration and wildlife habitat. The scientific discipline advancing the ecosystem services framework arose in the mid-1990s and quickly became a central strategy for fusing ecology and economics research. Despite its ascendance in research communities, the recognition and conservation of ecosystem …

An Old View Of The Cathedral: Intellectual Property Under The Colorado Uniform Partnership Act, Nathaniel T. Vasquez

University of Colorado Law Review

The Colorado Uniform Partnership Act ("CUPA") contains a subtle shortcoming. CUPA is a default statute that only operates in the absence of a governing agreement between two partners formed at the outset of the partnership. As with most things in this life, partnerships inevitably come to an end. When this happens, a partner is said to have "dissociated" from the partnership. Typically, this is followed by a dissolution of the partnership itself

Rather than terminating at that point, the partnership then goes into what is called the "winding up" period. Among other things, winding up involves liquidating all of the …

Dustbowl Waters: Doctrinal And Legislative Solutions To Save The Ogallala Aquifer Before Both Time And Water Run Out, Warigia M. Bowman

University of Colorado Law Review

Eighty-three years after the Dust Bowl, residents of America's High Plains face a dire threat: their primary aquifer faces depletion, and entire sections of the country are set to run out of groundwater by the end of the century or sooner.

The Ogallala Aquifer provides a significant amount of America's agricultural irrigation water and is a primary source of drinking water for Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming.

This Article argues that policymakers should slow the Aquifer's depletion rate by implementing changes to irrigation technology, crop choice, consumer behavior, legal doctrine, and legislation. This Article …

Recently, advances in transdermal drug delivery have offered avenues previously unattainable through conventional means. Some of these new delivery methods have been reviewed, explored and offer promising results with the potential to carve a new avenue in the way therapeutic …

Impact Of Phosphorus Intake On Beef Heifer Growth Performance And Conception Rates, Hailey Hilfiker, Beth Kegley, Rick Rorie, Jeremy Powell

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

In Northwest Arkansas, soil phosphorus concentrations have increased where livestock manures have been repeatedly applied, leading many to question if supplementing phosphorus in this area is necessary. The effects of phosphorus intake on beef heifer growth performance and conception rates were investigated. In this study, crossbred Angus heifers (n = 72), approximately 30 days after weaning, were stratified by body weight (average initial weight 251 ± 3.9 kg) and allocated randomly into 8 groups. Groups were assigned randomly to 1 of 2 treatments. Treatments were delivered through either a free-choice-mineral mix that contained no supplemental phosphorus (CON), or a free-choice-mineral …

Design And Characterization Of Thermal Inkjet Bioprinted Constructs For The Treatment Of Diabetic Foot Ulcers And Other Wound Healing Impaired Conditions, Luis Horacio Solis

Open Access Theses & Dissertations

Tissue engineering (TE) is a multidisciplinary practice focused on developing patient-specific constructs to repair, regenerate, or replace injured tissues and organs. One biofabrication process that has gained tremendous momentum in this field is bioprinting. Most, if not all bioprinting modalities embody the same principles of heat and shear due to mechanical forces or friction as cells are forced through narrow orifices. While it is important to examine the interaction between host and implanted constructs, it is also crucial to understand the direct effects that these bioprinting technologies have on cells before embedding them into TE applications.

The purpose of this …

A Short History Of The Public Trust Doctrine And Its Intersection With Private Water Law, Erin Ryan

Scholarly Publications

This article explores the development of public trust principles from early Roman and British law through modern U.S. law as a public commons approach to natural resource management, especially with regard to waterways. It then analyzes the tension between the common pool approach underlying the public trust regulation of waterways and the contrasting theoretical premises of American laws that regulate private use of the water within them—especially the privatization model embedded in the doctrine of prior appropriations, which assigns perpetual rights to withdraw from the watercourse on a first-in-time basis. The public trust doctrine, the protagonist of much modern environmental …

How Artists Can Capture Us: Educating About The Works Of Stephen Sondheim Through Parody, Jarrett Poore

Electronic Theses and Dissertations, 2020-2023

This thesis examined the modern renaissance man and his relationship between musical theatre history and parody; it examined how the modern artist created, produced, and facilitated an original parody in which humor can both influence and enhance an individual's interest in the art form. In the creation and production of The Complete Works of Stephen Sondheim [abridged], I showcased factual insight on one of the most prolific writers of musical theatre and infused it with comedy in order to educate and create appeal for Stephen Sondheim's works, especially those lesser known, to a wider theatrical audience. My two greatest research …

Meroitic Childhood Diet And Weaning At Sai Island, Sudan: A Carbon And Nitrogen Isotopic Study Of Site 8-B-52.B, Brenna Raisor

Electronic Theses and Dissertations, 2020-2023

This research explores the diet and weaning patterns of non-adult individuals from an elite Meroitic (300 BCE – 350 CE) cemetery (8-B-52.B) at Sai Island, Sudan. This was accomplished by conducting stable isotopic analyses of carbon and nitrogen on a sample of 54 individuals. These analyses focused on differences in adult and non-adult diet, non-adult weaning patterns, and intra-elite differences between contemporaneous cemeteries at Sai Island in order to shed light on the patterns of non-adult diet and weaning and the mother-infant dynamic. The non-adult individuals range from 36 weeks gestational age to 16.5 years of age, and the adult …

Playing Disability, Daniel Romano

Electronic Theses and Dissertations, 2020-2023

Disability in performance has a long history, starting with fictional characters such as Shakespeare's Gloucester/Richard, progressing through the freak shows of the early twentieth century, and finally with artists such as Neil Marcus, Mat Fraser and Deaf West Theatre in the past twenty years. Looking to the work of disabled artists, activists, and theorists such as Petra Kuppers and Carrie Sandahl, I will examine the history of both disability in performance and the performance of disability. I will discuss my performance of Garret, a man with muscular dystrophy, in my original play, The Sick Parents Club. Through analysis of what …

Non-Linear Inverse Liquid-Solid Chromatography As A Methodology To Characterize Drug Concentration Losses To Polymeric Materials Used In Body-On-A-Chip Devices For Drug Discovery, Mark Schnepper

Electronic Theses and Dissertations, 2020-2023

Body-on-a-chip and human-on-a-chip systems are currently being used to augment and could eventually replace animal models in drug discovery and basic biological research. However, hydrophobic molecules, especially therapeutic compounds, tend to adsorb to the polymer materials used to create these microfluidic platforms, which may distort the dose-response curves that feed into Pharmacokinetic/Pharmacodynamic (PK/PD) models which translate preclinical data into predictions of clinical outcomes. Adsorption of hydrophobic molecules to these polymer materials needs better characterization. Inverse Liquid-Solid Chromatography paired with a numerical optimization based on the Langmuir model of adsorption was used to characterize the adsorption isotherm parameters of selected drugs …

This research required participants to complete a pre-writing self-efficacy survey, participate in an interdisciplinary literacy unit and then complete a post writing self-efficacy survey. The interdisciplinary literacy unit took place during the distance learning environment that was a result of the global pandemic, …

Reconstruction Of Bacterial Strain Genomes From Shotgun Metagenomic Reads, Xin Li

Electronic Theses and Dissertations, 2020-2023

It is necessary to study bacterial strains in environmental samples. The environmental samples are mixed DNA samples collected from the ocean, soil, lake, human body sites, etc. In a natural environment, they provide us new insights into the diversity of our earth. As for bacterial strains on or inside human bodies, to select the proper treatment for diseases caused by bacterial strains, it is critical to identify the corresponding strains and reconstruct their genomes. However, it is a challenge to do so with the DNA from a large number of unknown microbial species mixed together in an environmental sample. The …

The Biological Manifestation Of Health, Culture, And Disease In Turn Of The Twentieth Century San Francisco, Trisha Walker

All Graduate Theses, Dissertations, and Other Capstone Projects

Between 1880 and 1920, a period known as the Great Migration, the city of San Francisco became one of the most diverse areas in the United States due to the steady arrival of immigrants. These groups of immigrants primarily consisted of individuals from China, Japan, Ireland, Italy, Eastern Europe, and Mexico. However, each of these groups faced various forms of xenophobia from American-born citizens when they tried to either earn a living or assimilate into American society. These immigrant groups were frequently impeded by who was, and who was not, considered to be “white” in the eyes of the dominant …

Entry Point For Assessing Sustainability In Ecotourism: Insights From Costa Rica (2020), Monica Mckeown

International Studies Undergraduate Honors Theses

Tourism is a rapidly growing industry and the prospect of development in smallcommunities from opening ecotourism enterprises is attractive to many. Increasingly, tourists are interested in visiting places for their natural beauty and adventure opportunities. Frameworks of assessment for the sustainability of ecotourism projects exist, but there is an absence of broader criteria meant to act as an entry point into the on-going process of sustainability assessment. In order for assessments to be more useful and easily conducted,there is a need for a new set of sustainability indicators. Because the ecotourism industry is growing rapidly, assessments are important in order …

Northwest African American Museum: Forging A Black Identity, Sadiqua Iman

Northwest African American Museum

The Northwest African American Museum opened in March, 2008, but had been in the works since 1985. During that time, community members, historians, and activists sometimes cooperated, sometimes argued over the best way to create an African American cultural center that could meet the needs of Seattle’s black community. Over the next twenty years, hardships, betrayals, and compromises would divide the African American community. When class, politics, economics, and racism must be reckoned with in building a new institution, change is the only constant and compromise the only solution. In the end, the Urban League of Metropolitan Seattle, the Black …

Social Media And Activism In The 2019/2020 Chilean Social Uprisings (2020), Julia Schwab

International Studies Undergraduate Honors Theses

As the current 2019/2020 social uprisings continue to sweep over Chile in resistance to neoliberal structural inequality and remanence of Augusto Pinochet’s 1973-1990 dictatorship, little research explores social media’s relationship with the movement. However, as the largest social movement since the dictatorship-era, 21st century digital media advancements and youth internet culture have significantly affected Chilean activism. The following paper will use historical analysis, social movement theory, and analysis of Twitter and Instagram posts to explore how social media is being used for social action in present day Chile. Results conclude that social media is a transformative catalyst in triggering spread …

The Effects That Family Form And Medical Practices Have On The Willingness Of Consumers To Adopt Entomophagous Practices, Mackenzie Conlon

Undergraduate Honors Thesis Projects

To help reduce amounts of destructive methane produced by livestock, climate activists are advocating for the inclusion of entomophagy in the mindset and culinary choices of Western society. Entomophagy, customary in most regions of the world, is seen as a deviant and disgusting food practice by most Westerners. In order to challenge this perception, producers of insect-based products are changing the appearance and marketability of their commodities. To successfully target markets, they need to determine the ideal household for entomophagy acceptance. My research tests the hypothesis that family form and medical practices affect the willingness of consumers to adopt these …

Cannabinoids As A Potential Therapeutic Treatment For Inflammatory Skin Disorders And Topical Phytocannabinoid Formulation Considerations, Hannah Korentur

Theses & ETDs

Due to the prevalence of chronic inflammatory skin diseases worldwide, new and effective treatments are constantly being considered and tested. The use of ​Cannabis sativa ​ L., also known as cannabis or marijuana, for pharmacological purposes has been controversial for decades due to its designation as a Schedule I drug. However, with a growing movement towards decriminalization, opportunities to understand the plant’s rich history, chemical complexity, and interactions with the human body have significantly increased. From this growth, the endocannabinoid system, a modulatory system that regulates a number of physiological and neurological functions, has been discovered in mammalian bodies. As …

Templated Single-Chain Polymer-Based Electrochemical Sensing, Habib Muhammad Nazir Ahmad

Master's Theses and Capstones

A target receptor is an essential component in developing selective biological and chemical sensors. Among various approaches in receptor implementation, templated polymers are synthetic biochemical receptors that mimic natural molecular recognition. They have the favorable arrangement of polymer structures to be steady in harsh conditions and can also be custom tailored to exhibit target affinity as well as interfacing with transducers. Effective templated polymer synthesis depends on the co-polymerization of functional monomers which will interact with the sensing molecule. This thesis proposes a rational design approach towards the integration of templated polymers with electrochemical sensing. The synthesized single-chain label-free flexible …

Developing Chenopodium Ficifolium As A Diploid Model System Relevant To Genetic Characterization And Improvement Of Allotetraploid C. Quinoa, Madhav Subedi

Master's Theses and Capstones

Quinoa, Chenopodium quinoa Willd., is a potential new high-value crop for Northern New England (NNE) because of its excellent nutritional qualities and its ability to grow in diverse agroecosystems. However, quinoa field trials have not been successful thus far in NNE because of some major issues such as downy mildew disease, severe lodging (bending over), excessive branching, overly long maturation time, and immature grains at harvest. Quinoa is an allotetraploid (2n=4x=36) species of genome composition AABB, and thus has two distinct diploid ancestors. This study reports foundational genetic studies in the BB diploid (2n=2x=18) ancestor, Chenopodium ficifolium, as a potential …

Objectives: Statin therapy has been associated with a decreased incidence of venous thromboembolism (VTE) in clinical trials and enhanced thrombus resolution in animal models. The effect of statins on thrombus resolution has not been reported clinically. This study investigates the association of statins with thrombus resolution or improvement in patients with deep vein thrombosis (DVT).

Methods: A retrospective study of the electronic medical records of consecutive adult patients presenting with lower extremity DVT was performed. Patients were divided into two groups based on statin therapy (statin group) or lack thereof (non-statin group). The two groups were compared with respect to …

Cerebral Autoregulation-Based Blood Pressure Management In The Neuroscience Intensive Care Unit: Towards Individualizing Care In Ischemic Stroke And Subarachnoid Hemorrhage, Andrew Silverman

Yale Medicine Thesis Digital Library

The purpose of this thesis is to review the concept of cerebral autoregulation, to establish the feasibility of continuous bedside monitoring of autoregulation, and to examine the impact of impaired autoregulation on functional and clinical outcomes following subarachnoid hemorrhage and ischemic stroke. Autoregulation plays a key role in the regulation of brain blood flow and has been shown to fail in acute brain injury. Disturbed autoregulation may lead to secondary brain injury as well as worse outcomes. Furthermore, there exist several methodologies, both invasive and non-invasive, for the continuous assessment of autoregulation in individual patients. Resultant autoregulatory parameters of brain …

Bottom-Up Herbivore-Plant Feedbacks Trump Trophic Cascades In A Wolf-Elk-Grassland System, Trevor C. Weeks

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Top-down predator-prey effects that alter the abundance, biomass, or productivity of a population community across more than one link in a food web are referred to as trophic cascades. While these effects have been extensively studied in aquatic environments, fewer studies have examined trophic cascades in terrestrial ecosystems. And fewer still terrestrial studies have tested for trophic cascades between vertebrates and grassland vegetation. Across the globe, grassland plant biomass is driven by both precipitation and non-linear positive feedbacks between grazing and plant productivity, as predicted by the Intermediate Grazing Hypothesis. Yet little is known about the role that apex carnivores …

Characterizing Retinal Ganglion Cell Responses To Electrical Stimulation Using Generalized Linear Models, Sudarshan Sekhar, Poornima Ramesh, Giacomo Bassetto, Eberhart Zrenner, Jakob H Macke, Daniel L. Rathbun

Ophthalmology Articles

The ability to preferentially stimulate different retinal pathways is an important area of research for improving visual prosthetics. Recent work has shown that different classes of retinal ganglion cells (RGCs) have distinct linear electrical input filters for low-amplitude white noise stimulation. The aim of this study is to provide a statistical framework for characterizing how RGCs respond to white-noise electrical stimulation. We used a nested family of Generalized Linear Models (GLMs) to partition neural responses into different components-progressively adding covariates to the GLM which captured non-stationarity in neural activity, a linear dependence on the stimulus, and any remaining non-linear interactions. …

Intracellular Localization Of The Novel Polyq Protein Fam171b, Dulanjani Rajaguru

All Graduate Theses, Dissertations, and Other Capstone Projects

FAM171B is a relatively uncharacterized protein that contains fourteen consecutive glutamine residues within its primary amino acid sequence; thus it is a polyglutamine (polyQ) protein. PolyQ proteins are interesting because mutations within the polyQ tract have been linked to a number of severe neurodegenerative diseases including Huntingtons Disease (HD). To date, there are minimal published data regarding FAM171B and its molecular function, such that both expression levels and intracellular localization have yet to be definitively determined. Using immunohistochemical and in situ hybridization analyses, our lab has recently found that FAM171B is expressed throughout the mouse brain. This current study attempts …

The Impact Of Income On Nutrition: A Case Study Of Northern Mozambique, Hunter Swanigan, Lawton Lanier Nalley

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

In 2017, Mozambique ranked as one of the least developed countries in the world by measures of health, education, and income. With a minimal annual income, purchasing adequate food to meet recommended levels of nutrients for a healthy diet is difficult, leaving 40% of the country undernourished. This study analyzed what foods are available during the dry months (hungry season) of May through October in the Nampula province of Mozambique to determine if it is possible to meet recommended levels of nutrients from purchasing and growing food. Three different levels of income were used to determine what percentage of the …
