Environmental Consciousness: Human Motivation For Thinking Ecologically, Rob Pigue

Student Theses 2001-2013

What is the motivation for acting environmentally? Why do people care? What is the reason for buying fluorescent bulbs and hybrid cars, energy efficient appliances and reusable water bottles? Why is it that people turn off the lights when they leave a room, turn off the faucet while brushing their teeth, and go through the inconvenience of recycling?

Humans are known to act out of self-interest. Regardless of what people do or why they do it, their motivation can always be traced back to personal gain.

So why go green? Nothing about reducing, reusing, or recycling has any direct impact …

Nesting Ecology Of The Mississippi And Swallow-Tailed Kite In White River National Wildlife Refuge, Arkansas, Scott James Chiavacci

Student Theses and Dissertations

The Swallow-tailed (Elanoides forficatus; STKI) and Mississippi kite (Ictinia mississippiensis; MIKI) both express relatively poor reproductive success in White River National Wildlife Refuge (WRNWR), east-central Arkansas. I studied the nesting ecology of both species in WRNWR to determine factors contributing to their low nest survival. I located 41 MIKI nests from 2008-2009 and documented 8 causes of nest failure. The overall estimated probability of nest survival was ~25%, but estimated daily nest survival varied between nest periods among and across years. I found no consistent predictors of nest survival among the variables I measured. Also, I determined snake excluder devices, …

A Study Of Genetic Structuring For Southern California Populations Of The Polychaete Nereis Grubei Using Inter Simple Sequence Repeats, Jignesh Anantray Chandarana

Student Theses and Dissertations

Members of the family Nereididae, including Nereis grubei, have a unique reproductive pattern among polychaetes- they reproduce a single time and possess a short larval period (4-5 days). This limits their potential to transmit their alleles to the next generation. Ocean currents also impact the magnitude and direction of gene flow. This study sampled 252 Nereis grubei from five coastal sites along southern California, two Channel Islands (Santa Cruz and Santa Catalina islands) and one central Mexico population using Inter Simple Sequence Repeats (ISSRs). Genetic diversity as measured by number of loci had a mean of 32, and expected heterozygosity …

Consistent Probabilities In Wheeler-Dewitt Quantum Cosmology, David A. Craig, Parampreet Singh

Faculty Publications

We give an explicit, rigorous framework for calculating quantum probabilities in a model theory of quantum gravity. Specifically, we construct the decoherence functional for the Wheeler-DeWitt quantization of a flat Friedmann-Robertson-Walker cosmology with a free, massless, minimally coupled scalar field, thus providing a complete decoherent histories formulation for this quantum cosmological model. The decoherence functional is applied to study predictions concerning the model's Dirac (relational) observables; the behavior of semiclassical states and superpositions of such states; and to study the singular behavior of quantum Wheeler-DeWitt universes. Within this framework, rigorous formulas are given for calculating the corresponding probabilities from the …

Minimum Description Length Measures Of Evidence For Enrichment, Zhenyu Yang, David R. Bickel

COBRA Preprint Series

In order to functionally interpret differentially expressed genes or other discovered features, researchers seek to detect enrichment in the form of overrepresentation of discovered features associated with a biological process. Most enrichment methods treat the p-value as the measure of evidence using a statistical test such as the binomial test, Fisher's exact test or the hypergeometric test. However, the p-value is not interpretable as a measure of evidence apart from adjustments in light of the sample size. As a measure of evidence supporting one hypothesis over the other, the Bayes factor (BF) overcomes this drawback of the p-value but lacks …

Integrated Freestanding Single-Crystal Silicon Nanowires: Conductivity And Surface Treatment, Chung-Hoon Lee, Clark Ritz, Minghuang Huang, Michael Ziwisky, Robert Blise, Max Lagally

Electrical and Computer Engineering Faculty Research and Publications

Integrated freestanding single-crystal silicon nanowires with typical dimension of 100 nm × 100 nm × 5 µm are fabricated by conventional 1:1 optical lithography and wet chemical silicon etching. The fabrication procedure can lead to wafer-scale integration of silicon nanowires in arrays. The measured electrical transport characteristics of the silicon nanowires covered with/without SiO₂ support a model of Fermi level pinning near the conduction band. The I–V curves of the nanowires reveal a current carrier polarity reversal depending on Si–SiO₂ and Si–H bonds on the nanowire surfaces

Improving Urban Stormwater Quality: Applying Fundamental Principles, Allen P. Davis, Robert G. Traver, William F. Hunt

Journal of Contemporary Water Research and Education

Urban stormwater runoff is a growing contributor to the impairment of surface waters. Nature-based technologies, including green roofs, vegetated swales, grassed filter strips, bioretention, and pervious pavements have been demonstrated to be effective in mitigating detrimental runoff characteristics. Lacking, however, has been a fundamental engineering analysis approach to these technologies. Current design guidance is based on empirical recommendations and most performance data are based on limited, localized observations. Flow balances, including infiltration, evapotranspiration and surface discharge, based on fundamental fluid dynamics principles can be employed through analysis to understand flow management. Water quality improvements will occur through a specific unit …

Application Of The Analytic Hierarchy Process For Selecting And Modeling Stormwater Best Management Practices, Kevin D. Young, Tamim Younos, Randel L. Dymond, David F. Kibler, David H. Lee

Journal of Contemporary Water Research and Education

Engineers are increasingly expected to consider several influential criteria when selecting a single best management practice (BMP) for stormwater management. These criteria include site physical characteristics; local, state, and federal pollution control ordinances; stakeholder input, and BMP implementation and long-term maintenance costs. This paper discusses the development of a software-aided approach based on the Analytic Hierarchy Process (AHP) as a decision-making tool for selecting stormwater management BMPs. Supported with input from a geographic information system, the AHP can provide an objective, mathematically-based alternative to the existing, often subjective BMP selection approaches. In this study, the developed AHP decision support software …

Watershed Retrofit And Management Evaluation For Urban Stormwater Management Systems In North Carolina, Kathy M. Debusk, William F. Hunt, Upton Hatch, Olha Sydorovych

Journal of Contemporary Water Research and Education

In response to water quality concerns in the Jordan Lake Reservoir and state and federal mandates, several cities in North Carolina are being required for the first time to reduce nutrient loads in stormwater from previously developed lands; that is, install retrofits. It is anticipated that similar requirements will become necessary for other urban areas in North Carolina. The goal of this study is to evaluate the feasibility of alternative approaches to stormwater management for existing developments within North Carolina cities. Geographic coverage of the study included a portion of the New Hope Creek watershed, located within the City of …

The Pseudomonas Aeruginosa Magnesium Transporter Mgte Inhibits Transcription Of The Type Iii Secretion System, Gregory G. Anderson, Timothy L. Yahr, Rustin R. Lovewell, George A. O'Toole

Dartmouth Scholarship

Pseudomonas aeruginosa is an opportunistic pathogen that causes life-long pneumonia in individuals with cystic fibrosis (CF). These long-term infections are maintained by bacterial biofilm formation in the CF lung. We have recently developed a model of P. aeruginosa biofilm formation on cultured CF airway epithelial cells. Using this model, we discovered that mutation of a putative magnesium transporter gene, called mgtE, led to increased cytotoxicity of P. aeruginosa toward epithelial cells. This altered toxicity appeared to be dependent upon expression of the type III secretion system (T3SS). In this study, we found that mutation of mgtE results in increased T3SS …

Wetlands And Ponds For Stormwater Treatment In Subtropical Australia: Their Effectiveness In Enhancing Biodiversity And Improving Water Quality?, Margaret Greenway

Journal of Contemporary Water Research and Education

Stormwater best management practice is aimed at reducing potential downstream impacts on aquatic ecosystem health. Sediment basins, wetlands and ponds are commonly used in subtropical Australia for water-quality improvement; they also have the potential to enhance aquatic biodiversity in urbanised catchments. Two retrofit field sites in Brisbane, Australia were monitored for water quality and ecosystem health. The Golden Pond "wetland system" treatment train consisted of a sediment basin and two wetlands. The Bridgewater Creek "pond system", consisted of a sediment basin and five ponds. Suspended solids were reduced during wet weather, but increased during dry weather due to resuspension by …

Haunting Witnesses: Diasporic Consciousness In African American And Caribbean Writing, Brandi Bingham Kellett

Open Access Dissertations

This project examines the ways in which several texts written in the late twentieth century by African American and Caribbean writers appropriate history and witness trauma. I read the representational practices of Toni Morrison, Ernest Gaines, Paule Marshall, and Fred D'Aguiar as they offer distinct approaches to history and the resulting effects such reconstituted, discovered, or, in some cases, imagined histories can have on the affirmation of the self as a subject. I draw my theoretical framework from the spaces of intersection between diaspora and postcolonial theories, enabling me to explore the values of the African diaspora cross-culturally as manifested …

Earlier Buddhist Theories Of Free Will: Compatibilism, Rick Repetti

Publications and Research

This is the first part of a three-article series that examines Budd-hist accounts of free will. The present article introduces the issues and reviews earlier attempts by Frances Story, Walpola Rāhula, Luis Gómez, and David Kalupahana. These “early-period” authors advocate compatibilism between Buddhist doctrine, determinism (the doctrine of universal lawful causation), and free will. The second article reviews later attempts by Mark Siderits, Gay Watson, Joseph Goldstein, and Charles Goodman. These “middle-period” authors embrace either partial or full incompatibilism. The third article reviews recent attempts by Nicholas F. Gier and Paul Kjellberg, Asaf Federman, Peter Harvey, and B. Alan Wallace. …

The majority of injuries sustained in Operation Endearing Freedom/Operation Iraqi Freedom (OEF/OIF) are combined penetrating, burn and blast injuries, traumatic amputation, and infections from the multi-drug resistant organism, Acinetobacter (Melcer, 2010). The purpose of this study was to measure the quality of well-being and impact of events in a group of adults who served in the U.S. armed forces and sustained the loss of one or more limbs during any combat or …

Does Entropic Gravity Bound The Masses Of The Photon And Graviton?, Jonas R. Mureika, R. B. Mann

Physics Faculty Works

If the information transfer between test particle and holographic screen in entropic gravity respects both the uncertainty principle and causality, a lower limit on the number of bits in the universe relative to its mass may be derived. Furthermore, these limits indicate particles that putatively travel at the speed of light -- the photon and/or graviton -- have a non-zero mass m≥10−68 kg. This result is found to be in excellent agreement with current experimental mass bounds on the graviton and photon, suggesting that entropic gravity may be the result of a (recent) softly-broken local symmetry. Stronger bounds emerge …

Unl Physicists Model Potential 4-D Imaging Technique, Tom Simons, Hua-Chieh Shao, Anthony F. Starace

A long-standing goal of science is to be able to understand how matter behaves at the atomic and subatomic level. How electrons rearrange when atoms or molecules come together is the essence of chemistry, and the ability to manipulate those rearrangements is the goal of the emerging sphere of nanotechnology. A fuller understanding could lead to enormous scientific and technological breakthroughs. Unfortunately, significant problems confront scientists and engineers in attacking the question. Not only are atoms and molecules very small, requiring highly specialized equipment to "see" them, everything at the atomic level happens very, very fast. For example, an electron …
