Patterns Of Habitat Use By Bats Along A Riparian Corridor In Northern Utah, Duke S. Rogers, Mark C. Belk, Malinda W. González, Brent L. Coleman

Faculty Publications

We examined patterns of habitat use within a community of bats along the Provo River in Heber Valley, Utah. The landscape was divided into 5 habitat categories: riparian forest, wetland, agricultural field, edge, and a habitat restoration site. We used Anabat II bat detectors to record the number of echolocation calls per night within each habitat type as an index of bat activity. Echolocation calls were classified into foraging guilds based on acoustic traits, and we analyzed activity by entire community and by the 4 guilds related to habitat type and environmental variables. Activity was not significantly related to moon …

Pakootas V. Teck Cominco Metals, Ltd.: Finding A Sustainable Solution To Transboundary Pollution, Kate Mcdonald

Georgia Law Review

Transboundary pollution has become an issue of increasing concern as scientists learn more about the global effects of industry pollutants and the harm they pose to human health. - Advances in our understanding of the environment opened the door to disputes over responsibility for prevention and mitigation of the harmful effects of pollutants and created a search for techniques for international conflict resolution. Recently, industrial pollution of the Columbia River resulted in a legal battle between Washington citizens and a Canadian corporation over who was financially responsible for restoring the health of a portion of the river lying within the …

Rescuing Judicial Accountability From The Realm Of Political Rhetoric, Charles G. Geyh

Articles by Maurer Faculty

The article examines the threat to judicial independence from political calls for more judicial accountability. The author begins by defining judicial accountability and discussing its purposes before breaking the concept down into three categories: institutional accountability, behavioral accountability, and decisional accountability. This process reveals that in the judicial accountability family, there is but one discrete sub-species, situated in the decisional accountability genus, that does not further accountability's proper purpose and is therefore conceptually problematic: direct political accountability for competent and honest judicial decision-making error that the politicians desire and a serious threat to judicial independence. The critical question becomes one …

Regarding Pained Sympathy And Sympathy Pains: Morality, And Empathy In The Civil Adjudication Of Pain, Jody L. Madeira

Articles by Maurer Faculty

This Essay considers the legal propriety of the empathic responses of jurors to suffering plaintiffs. To that end, Part II first explicates the legal contours of a tension between what is experiential or physical (objective) and what is expressionistic or non-physical (subjective). This tension is a foundational jurisprudential concern in personal injury litigation because the subjective is seen to threaten the rule of law: the perceived primacy of reason and logic. Thus, this tension is also what the parties' attorneys seek to exploit and what the court seeks to constrain. Part III explores why an empathic identification is indeed a …

Recognizing Odysseus' Scar: Reconceptualizing Pain And Its Empathic Role In Civil Adjudication, Jody L. Madeira

Articles by Maurer Faculty

This Article proffers a consideration of how the expression of pain impacts the interpersonal dimensions of personal injury proceedings, contesting through philosophical logic and textual analyses of case law and legal practitioners' texts the conclusion of scholars such as Elaine Scarry and Robert Cover that pain unmakes both the word and the world. Seeing pain as something that can and must be communicated, albeit in a different form than pain embodied, makes pain a much more profound force, comports with our understanding of pain as a physical yet interpersonally meaningful sensation, and has many evidentiary ramifications. Taking as its premise …

"Mirror Worlds": Transpacific Inspiration And Mimetic Rivalry In American And East Asian Literature, 1945-2005., Matthew J. Packer

Graduate Theses, Dissertations, and Problem Reports (ETD)

One conspicuous trend during the world economy's shift to the Pacific Rim in the late twentieth century has been the increased reciprocal inspiration and mimetic rivalry between American and East Asian cultures. For much of the past century, for example, the Japanese have been stereotyped as cultural copycats, when transpacific imitating actually has been mutual: as East Asians have looked to the West for models of development and the imagination, so have Americans looked to the Far East---as even representing the future, according to novelist William Gibson. Americans have drawn inspiration from Eastern aesthetics, while East Asians have copied Western …

De Novo Asymmetric Syntheses Of Biologically Important Natural Products: Phomopsolide D, Phomopsolide E, Milbemycin Beta3 And Apicularen A., Miaosheng Li

Graduate Theses, Dissertations, and Problem Reports (ETD)

De novo asymmetric synthesis is a strategy that uses asymmetric catalysis to construct chiral molecules from achiral starting materials. One of the advantages of this strategy is that we can synthesize numerous stereoisomers (e.g. the enantiomers) of the target natural product for biological testing. Substituted α,β-unsaturated δ-lactones are an important class of natural products with a wide range of biological activity. Many synthetic methodologies have been developed to synthesize this core structure. However, they depended on either performing kinetic resolutions or chiral starting materials (e.g. carbohydrates). We envisioned using catalytic asymmetric catalysis (de novo approach) to synthesize these complex molecules. …

Quantification Of Doxorubicin Concentration In Rat Tissues Using Polymeric Micelles In Ultrasonic-Drug Delivery, William G. Pitt, Beverly Roeder, Bryant J. Staples

Faculty Publications

The triblock copolymer, Pluronic P105, has been found to be an ideal ultrasonically activated drug delivery vehicle because it forms micelles with hydrophobic polypropylene oxide cores that sequester hydrophobic drugs (Fig. 1). These micelles release their contents upon the application of low frequency ultrasound [1]such that drugs can be released specifically at the ultrasonicated region (Fig. 2). Such ultrasonically controlled release has been effective against cancer cells in vitro [2] and in vivo [3]. The purpose of this research is to assess the use of these novel polymeric micelles in ultrasonically-activated Doxorubicin® (DOX) delivery to tumors. This cancer therapy involves …

George Eliot And The Anxious Construction Of The Domestic Other: Racial Inheritance, Radical Femininity And Masculinity, And National Identity In "The Spanish Gypsy" And "Daniel Deronda"., Christina E. Godlewski

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation seeks to articulate the extent to which George Eliot engages in an active dialogue with contemporary scientific thought, particularly in respect to England's Jewish and Gypsy populations. I examine The Spanish Gypsy and Daniel Deronda to determine Eliot's position in relation to ideologies on race, gender, and class. Eliot's texts manage to expose some of the contradictions regarding these two "domestic others" within the dominant discourses of the Victorian period. Chapter one sets out my critical and methodological framework and foregrounds the discursive proximity between the Gypsies, the Jews, the working classes, and women in the Victorian period. …

Hepatic Α-Aminoadipate Δ-Semialdehyde Synthase Appears To Be Post-Translationally Regulated In Mouse And Chicken., Aaron S. Kiess

Graduate Theses, Dissertations, and Problem Reports (ETD)

 Lysine is the limiting amino acid in many animal diets. Improving the efficiency of lysine use for protein synthesis can reduce feed cost and potentially the nitrogen and phosphorus output of agricultural production systems. Lysine not used for protein synthesis is oxidized, primarily by lysine α-ketoglutarate reductase (LKR). The mechanism(s) responsible for alterations in hepatic LKR activity in rodents and poultry are still unclear. For this reason, studies in both species were conducted to evaluate possible mechanisms responsible for alterations of LKR activity. Mice were fed either a high or adequate protein diet. Mice fed the high protein diet had …

Surrendered Resistance: Playing Dead In American Autobiographical Writing, 1840-1933., Georgia R. Kreiger

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation focuses on the use of death as a metaphor for lived experiences in nineteenth- and early twentieth-century American autobiographical writing. Adopting Paul de Man’s definition of autobiography as a figure of reading rather than a genre or mode, the study analyzes autobiographical death acts in a variety of writings, including political discourse, fiction, and poetry. The writers discussed stage deaths-of-the-self to facilitate descriptions of traumatic events that might otherwise defy verbal expression. They “play dead” figuratively in their texts, similarly to the way one might play dead literally as a survival strategy in the presence of an animal …

Effects Of Various Environmental Parameters On The Reduction Of Arsenic(V) To Arsenic(Iii) By Dissolved Organic Matter., Tsanangurayi Tongesayi

Graduate Theses, Dissertations, and Problem Reports (ETD)

The objective of this study was to investigate the reduction of inorganic As(V) with Suwannee River fulvic acid (FA) in aqueous solutions and in real samples. Samples of inorganic As(V) were incubated with FA under various solution conditions and aliquots from the incubated samples were taken at various time intervals and analyzed for As(III) using square wave cathodic stripping voltammetry at a hanging mercury drop electrode. The study demonstrated the following important aspects of As speciation: (1) FA can significantly reduce As(V) to As(III), (2) Reduction of As(V) to As(III) is a function of pH, (3) Reduction of As(V) to …

A Simple, Inexpensive, And Effective Light- Carrying Laryngoscopic Blade For Orotracheal Intubation Of Rats, Robert C. Molthen

Biomedical Engineering Faculty Research and Publications

The research paradigm of using large laboratory animals, in which oroendotracheal intubations are relatively easy, is shifting toward the use of small animals, such as rodents, in which oropharyngeal access is limited, the arytenoid cartilage cycles are faster, and the glottis is much smaller. The considerable growth recently seen in preclinical imaging studies is accompanied by an increased number of rats and mice requiring in vivo intubation for airway management. Tracheal access is important for ventilation, administration of inhaled anesthetics, instillation of drugs or imaging agents, and maintenance of airway patency to reduce mortality during and after operations. I fashioned …

Lives, Livelihoods, And Landscapes: A Study Of Land Use And Social Change In Northeastern Nepal, Jennifer Leigh Anderson

Dissertations and Theses

This thesis explores the forces of change in lives and landscapes that have altered the Lamosangu-to-Everest route in northeastern Nepal and shows how a transect in photographs and conversations across the east-central Himalaya allows us insight and a greater understanding into the processes and consequences of this change.

Three forces of change over the last twenty-five years dominated discussions with local informants: the rise of the "People's War"-Nepal's Maoist Insurgency beginning in 1996; the Democratic Revolution of 1990; and dependence on tourism for livelihood after the establishment of Sagarmatha National Park in 1976. Understanding the cultural-historical context for these forces …

Adverse Possession And Conservation: Expanding Traditional Notions Of Use And Possession, Alexandra B. Klass

University of Colorado Law Review

At common law, very minimal actions were needed to establish the "exclusive possession " necessary to acquire land by adverse possession when the land was "wild" or undeveloped. This minimal burden to adversely possess wild lands, which is still the general rule today, stands in contrast to the much higher standard necessary to adversely possess developed lands. This article explores why the lesser standard for adverse possession of wild lands remains a threat to many of the millions of acres of land in this country that are still undeveloped. This article then proposes that courts modernize the adverse possession doctrine …

Is Cost-Benefit Analysis Neutral, David M. Driesen

University of Colorado Law Review

Cost-benefit analysis (CBA) owes much of its appeal to its image as a neutral principle for deciding upon the appropriate stringency of environmental, health, and safety regulation. This Article examines whether CBA is neutral in effect-i.e. whether it sometimes makes regulations more stringent or regularly leads to weaker environmental, health, and safety protection. Using a representative data set from recent Office of Management and Budget (OMB) reviews, an examination of OMB prompt letters, and a literature review, this Article shows that CBA has almost always proven anti-environmental in practice. It also shows that the most common approaches to CBA are …

The Shrinking Scope Of Judicial Review In Norton V. Southern Utah Wilderness Alliance, Justin C. Konrad

University of Colorado Law Review

In Norton v. Southern Utah Wilderness Alliance, the U.S. Supreme Court issued its first decision definitively construing § 706(1) of the Administrative Procedure Act ("APA"). This section ostensibly provides for review of agency action "unlawfully withheld or unreasonably delayed." However, the Court's opinion narrowly construed section 706(1) so as to allow review only for discrete agency actions that are legally required. As a result, the Court held that Bureau of Land Management compliance with a Federal Land Management and Policy Act ("FLPMA") provision mandating management of certain public lands so as to prevent impairment of their wilderness characteristics was not …

Polyetheretherketone As A Biomaterial For Spinal Applications, Jeffrey M. Toth, Mei Wang, Bradley T. Estes, Jeffrey L. Scifert, Howard B. Seim, A. Simon Turner

Biomedical Engineering Faculty Research and Publications

Threaded lumbar interbody spinal fusion devices (TIBFD) made from titanium have been reported to be 90% effective for single-level lumbar interbody fusion, although radiographic determination of fusion has been intensely debated in the literature. Using blinded radiographic, biomechanic, histologic, and statistical measures, we evaluated a radiolucent polyetheretherketone (PEEK)-threaded interbody fusion device packed with autograft or rhBMP-2 on an absorbable collagen sponge in 13 sheep at 6 months. Radiographic fusion, increased spinal level biomechanical stiffness, and histologic fusion were demonstrated for the PEEK cages filled with autograft or rhBMP-2 on a collagen sponge. No device degradation or wear debris was observed. …

Recent Trends In Robot-Assisted Therapy Environments To Improve Real-Life Functional Performance After Stroke, Michelle J. Johnson

Biomedical Engineering Faculty Research and Publications

Upper and lower limb robotic tools for neuro-rehabilitation are effective in reducing motor impairment but they are limited in their ability to improve real world function. There is a need to improve functional outcomes after robot-assisted therapy. Improvements in the effectiveness of these environments may be achieved by incorporating into their design and control strategies important elements key to inducing motor learning and cerebral plasticity such as mass-practice, feedback, task-engagement, and complex problem solving.

This special issue presents nine articles. Novel strategies covered in this issue encourage more natural movements through the use of virtual reality and real objects and …

Development Of Single Nanoparticle Optical Assays For Imaging Single Living Cells, William John Brownlow

Chemistry & Biochemistry Theses & Dissertations

Multi-drug resistance (MDR) has been reported in both prokaryotes and eukaryotes; the pathogenic gram-negative bacteria Pseudomonas aeruginosa can extrude a variety of structurally and functionally diverse substrates via a number of membrane transport systems leading to MDR. We have developed a novel nanoparticle assay to characterize both the membrane transport system composed of the MexAB-OprM efflux pump and the membrane permeability induced by antibiotics. Gold (Au) and silver (Ag) nanoparticles were investigated for use as probes to explore membrane transport in P. aeruginosa.

The surface plasmon absorption (color) of Au nanoparticle solutions was found to change in the presence …

Structure-Function Studies Of The Camp-Dependent Protein Kinase In Vitro And In Intact Cells, Gary Z. Morris

Theses and Dissertations in Biomedical Sciences

There are 518 protein kinase genes in the human genome; this constitutes about 1.7% of all human genes. The cAMP-dependent protein kinase (PKA) serves as the prototypic model for the study of kinases because it contains a conserved catalytic core shared with all eukaryotic kinases, it is the simplest kinase, and it is one of the best-characterized serine/threonine kinases. PKA is ubiquitous in mammals and regulates multiple physiological mechanisms such as the cell cycle, apoptosis, cell motility, energy metabolism, and gene transcription through a well-defined intracellular signaling pathway. While PKA clearly has a central physiological role it is still unclear …

Understanding The Nature Of Surgical Excellence Using A Competency Modeling Approach, Hope S. Hanner-Bailey

Psychology Theses & Dissertations

Currently, a thorough description of the knowledge, skills, abilities, and other personal characteristics (KSAOs) that distinguish an exceptional surgeon does not exist. This knowledge is pertinent to the development of selection, training, and performance assessment methods that can be used to develop high performing surgeons. Expert surgeons from around the country were recruited to participate in an interview to discuss the KSAOs (i.e., the competencies) needed to be exceptional in the field. A smaller number of novice surgeons were also interviewed. The expert interview data were distilled into a competency model that consists of ten competencies and patterns within the …

Age Validation And Reproductive Biology Of Bluefish, Pomatomus Saltatrix, Along The East Coast Of United States, Eric Robillard

OES Theses and Dissertations

I describe a new preparation technique that increases readability of otoliths, along with criteria for the interpretation of otolith microstructure of bluefish, Pomatomus saltatrix, collected from Florida to New York during 2001-2003 (n = 2652). I validated annulus formation in otoliths for ages 1 to 8 using marginal increment analysis and thus extended validation by four years to include the preponderance of age classes in the catch. Although otoliths are typically superior for ageing, bluefish are routinely aged with scales; thus a side-by-side comparison of otoliths versus scales is necessary before otoliths can supplant scales. When compared, precision …

Importance De L'Organisation Du Travail Comme Soutien Aux Stratégies Protectrices Des Afs Et Des Infirmières Des Services De Soins Et De Maintien À Domicile, Esther Cloutier, Hélène David, Élise Ledoux, Madeleine Bourdouxhe, Catherine Teiger, Isabelle Gagnon, François Ouellet

Rapports de recherche scientifique

Une étude exploratoire réalisée en 1998, a montré que les emplois d’auxiliaires (AFS) et d’infirmières sont les deux emplois les plus nombreux en termes d’effectifs dans les CLSC au Québec et qu’ils présentent des risques importants pour la santé et la sécurité (SST). Elle montrait aussi que l’organisation du travail peut soutenir de manière plus ou moins efficace les travailleuses par différentes mesures. Le secteur de la santé est en croissance, la main-d’œuvre y est vieillissante; plusieurs recrues devront être engagées et conservées. Une nouvelle recherche a donc été réalisée afin d’étudier le rôle de l’organisation du travail des services …

Statins And The Vasculopathy Of Systemic Sclerosis: Potential Therapeutic Agents?, Chris T. Derk, Sergio A. Jimenez

Department of Medicine Faculty Papers

It has been postulated that endothelial cell injury is the initiating event in the pathogenesis of systemic sclerosis, causing attraction, attachment, migration and infiltration of activated T-cells and subsequent production of cytokines and growth factors. As a result of the action of these cytokines and growth factors, chemoattraction of fibroblasts into the vessel wall and transdifferentiation of resident fibroblasts and smooth muscle cells into myofibroblasts occur leading to fibrosis and exaggerated collagen deposition in the vessel wall. To date, the therapeutic options for the vasculopathy of systemic sclerosis have been limited to drugs that cause vasodilation and inhibit platelet aggregation …

Molecular Characterization Of A Tsetse Fly Midgut Proteolytic Lectin That Mediates Differentiation Of African Trypanosomes, Laila U. Abubakar, Wallace D. Bulimo, Francis J. Mulaa, Ellie O. Osir

All Peer-Reviewed Publications

Differentiation of bloodstream-form trypanosomes into procyclic (midgut) forms is an important first step in the establishment of an infection within the tsetse fly. This complex process is mediated by a wide variety of factors, including those associated with the vector itself, the trypanosomes and the bloodmeal. As part of an on-going project in our laboratory, we recently isolated and characterized a bloodmeal-induced molecule with both lectin and trypsin activities from midguts of the tsetse fly, Glossina longipennis [Osir, E.O., Abubakar, L., Imbuga, M.O., 1995. Purification and characterization of a midgut lectin-trypsin complex from the tsetse fly, Glossina longipennis. Parasitol. Res. …

Initial Evaluation Of Novel Preparations Of Bordetella Avium By Determination Of Antibody Response Titers, Joel Gallagher, Stacy Higgins, Luc Berghman, Billy Hargis

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

The efficacy of killed vaccines generally is not equal to live vaccines. However, due to safety and ease of production, they remain a vital part of controlling and preventing diseases. In this study, the immune response to four different vaccination preparation techniques for the agent of bordetellosis of turkeys, Bordetella avium (BA), was compared. Preparation/inactivation techniques included (1) formalin inactivation, (2) opsonization of formalin-inactivated BA, (3) buffered acetic-acid BA inactivation, or (4) opsonization of buffered acetic-acid-inactivated BA. Non-adjuvated suspensions containing equal antigen mass were administered subcutaneously (0.2 mL) at day-of-hatch in all cases. For each treatment (N=40/treatment), plasma samples were …
