Energy-Environment Policy Alignments, Todd S. Aagaard Dec 2015

Energy-Environment Policy Alignments, Todd S. Aagaard

Faculty Publications

Energy law focuses on making energy widely available at reasonable cost, and environmental law focuses on preventing pollution. As a result of these differences in their respective orientations, the two fields often work incoherently and even in conflict. Historically, federal energy law and environmental law have attempted to manage their interrelationships by imposing negative constraints on each other: Energy policies of the Federal Energy Regulatory Commission (FERC) must comply with requirements set forth in environmental statutes, and the Environmental Protection Agency’s (EPA’s) statutes contain energy-related requirements and exemptions. More recently, however, FERC and EPA have begun developing policies that create …

A Phenomenological Study Of First-Generation Latino Graduates Of Community College And Protective Factors Of Academic Resilience, Homiler Elie Phanor Dec 2015

A Phenomenological Study Of First-Generation Latino Graduates Of Community College And Protective Factors Of Academic Resilience, Homiler Elie Phanor

Education Doctoral

This study examined the reasons behind first-generation Latino students’ academic success in attaining associate degrees in community colleges in the United States, focusing specifically on academic resilience factors among this cohort. The research comes in response to the awareness that, despite the U.S.’s rapidly growing Latino population, Latinos have the lowest higher education attainment level compared to all other ethnic groups. While the structural factors behind this have been examined, there is relatively little research on the enabling factors driving Latinos, specifically those who are first-generation students, who do successfully complete higher education degrees in community colleges, their main entry …

Ways Of Knowing, Learning, And Being: Exploration Of The Educational Culture, Learning Experiences, And The Persistence Of Male Students In Associate Degree Nursing Programs In New York State, Loretta G. Quigley Dec 2015

Ways Of Knowing, Learning, And Being: Exploration Of The Educational Culture, Learning Experiences, And The Persistence Of Male Students In Associate Degree Nursing Programs In New York State, Loretta G. Quigley

Education Doctoral

Currently, studies show that men are underrepresented in the nursing profession. The Health Resources and Services Administration (2013) found that although men comprise 49% of the population, only 9% of the nursing workforce is male. Additionally, there are predictions of an impending nursing shortage, related in part to an ageing nursing workforce and health care reform. Increasing the number of men could be a possible solution to the shortage. This may be accomplished by retaining male students in nursing education, although studies have identified many factors that impact negatively on their retention. The National Advisory Council on Nurse Education and …

Short Term Effectiveness Of High Density Large Woody Debris In Asotin Creek As A Cheap And Cheerful Restoration Action, Reid Camp Dec 2015

Short Term Effectiveness Of High Density Large Woody Debris In Asotin Creek As A Cheap And Cheerful Restoration Action, Reid Camp

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In response to human impacts, river restoration and rehabilitation actions have become a priority in the United States. In the Pacific Northwest, most restoration actions are focused on repairing degraded freshwater habitat to increase or improve Pacific salmonid production. However, traditional river restoration actions remained largely unchanged for over 100 years despite a lack of definitive evidence that the actions were effective. More recently, there has been a surge in process-based restoration actions, which aim to reestablish the physical and biological processes that maintain fluvial and floodplain environments by targeting the root causes of degradation in a watershed. Cheap and …

Changing Behavior, Brain Differences, Or Both? A Review Of Effective Adhd Treatment, Devin Hilla Dec 2015

Changing Behavior, Brain Differences, Or Both? A Review Of Effective Adhd Treatment, Devin Hilla

Honors Projects

Much debate exists over the proper course of treatment for individuals with attention-deficit/hyperactivity disorder (ADHD). Stimulant medications, such as methylphenidate (e.g., Ritalin) and amphetamine (e.g., Adderall), have been shown to be effective in managing ADHD symptoms. More recently, non-stimulant medications, such as atomoxetine (e.g., Strattera), clonidine (e.g., Kapvay), and guanfacine (e.g., Intuniv), have provided a pharmacological alternative with potentially lesser side effects than stimulants. Behavioral therapies, like behavioral parent training, behavioral classroom management, and behavioral peer interventions, have shown long-term benefits for children with ADHD; however, the success of the short-term management of ADHD symptoms is not as substantial when …

© 2015 The Authors. Published by Elsevier B.V.. Vitamin D is getting more attention everyday due to its importance in maintaining bone and calcium homeostasis, cellular proliferation, differentiation and immune response. Vitamin D is derived from diet or elicited in the skin by the activation of 7-dehydrocholesterol, which is an inert molecule that must be activated by ultraviolet light to form pre-vitamin D3. Recent studies connected the gene encoding for vitamin D (VDR) to the genetic control of bone mass and other diseases. As VDR SNPs have been associated with several disorders and diseases, it's important to investigate the allelic …

Happiness In Modern Society: Why Intelligence And Ethnic Composition Matter, Satoshi Kanazawa, Norman P. Li Dec 2015

Happiness In Modern Society: Why Intelligence And Ethnic Composition Matter, Satoshi Kanazawa, Norman P. Li

Research Collection School of Social Sciences

Recent developments in evolutionary psychology suggest that living among others of the same ethnicity might make individuals happier and further that such an effect of the ethnic composition on life satisfaction may be stronger among less intelligent individuals. Data from the National Longitudinal Study of Adolescent Health showed that White Americans had significantly greater life satisfaction than all other ethnic groups in the US and this was largely due to the fact that they were the majority ethnic group; minority Americans who lived in counties where they were the numerical majority had just as much life satisfaction as White Americans …

Economic Status And Old-Age Health In Poverty-Stricken Myanmar, Bussarawan Teerawichitchainan, John Knodel Dec 2015

Economic Status And Old-Age Health In Poverty-Stricken Myanmar, Bussarawan Teerawichitchainan, John Knodel

Research Collection School of Social Sciences

Objective: We examine the association between poverty, economic inequality, and health among elderly in Myanmar. Method: We analyze 2012 data from Myanmar’s first representative survey of older adults to investigate how health indicators vary across wealth quintiles as measured by household possessions and housing quality. Results: Poverty and poor health are pervasive. Self-assessed health, sensory impairment, and functional limitation consistently improve with higher wealth levels regardless of socio-demographic controls. Differentials in self-rated health and sensory impairment between the bottom and second quintiles are clearly evident, suggesting that relative economic inequality matters even among very poor elders and that a small …

Galvanic Corrosion Of Magnesium Coupled To Steel At High Cathode-To-Anode Area Ratios, Dila Ram Banjade Dec 2015

Galvanic Corrosion Of Magnesium Coupled To Steel At High Cathode-To-Anode Area Ratios, Dila Ram Banjade

Theses and Dissertations

In this study, the impact of galvanic coupling of magnesium to steel on the corrosion rate, surface morphology, and surface film formation was investigated. In particular, the role of self-corrosion was quantified as previous studies showed discrepancies between model predictions and experimental results that were likely due to significant self-corrosion. This experimental study examined the corrosion of Mg coupled to steel in 5 wt% NaCl at cathode-to-anode area ratios that ranged from 5 to 27. Results showed that self-corrosion was significant and accounted for, on average, one-third of total corrosion. Moreover, self-corrosion varied with time and cathode size, and was …

Third Ventricle Width As A Metric For Fast And Efficient Detection Of Atrophy In Traumatic Brain Injury, Christopher Scott Finuf Dec 2015

Third Ventricle Width As A Metric For Fast And Efficient Detection Of Atrophy In Traumatic Brain Injury, Christopher Scott Finuf

Theses and Dissertations

In an average year more than 1.7 million people will experience a traumatic brain injury (TBI) in the United States. It is known that atrophy occurs across a spectrum for TBI patients, ranging from mild to severe. Current conventional magnetic resonance imaging (MRI) methods are inconsistent in detecting this atrophy on the milder end of the spectrum. Also more contemporary imaging tools, although efficient, are too time consuming for clinical applicability. It is for these reasons that a quick and efficient measurement for detecting this atrophy is needed by clinicians. The measuring of third ventricle width had the potential to …

Evidence Of Ancient Maya Agriculture In The Bajos Surrounding Tikal, Guatemala, Adam Calvin Parker Dec 2015

Evidence Of Ancient Maya Agriculture In The Bajos Surrounding Tikal, Guatemala, Adam Calvin Parker

Theses and Dissertations

Current Central American agricultural practices are environmentally and economically unsustainable, yet the ancient Maya who lived in the same region thrived for thousands of years. Archaeologists have attempted to understand the factors enabling the prolonged success and ultimate collapse of the Maya societies. Some have proposed that the karst seasonal wetlands, called bajos, that border many Maya sites in the region were an influential factor in the Maya's ability to flourish. For the past decade, researchers have used carbon isotope analyses to identify areas of ancient maize agriculture at Maya archaeological sites. In this study, we collected soil samples from …

Reject Or Redemptive Fathers? A Content Analysis Of Father Portrayals In Top Box Office Family Films, Cassidy Jo Wadsworth

Theses and Dissertations

More research is needed to fully understand the way in which parents, particularly fathers, are portrayed in family films and the effects those portrayals might have. Viewers, particularly parents, need to understand how the material their children view presents reality and how it may shape their children's perspectives of the real world, particularly where the family unit and parenting role are concerned. By exploring these portrayals through the lens of Cultivation Theory, this study sought to answer this overarching question: How are fathers portrayed in family films as opposed to television? This quantitative study explores the top twenty films from …

Stochastic Simulation Of Lagrangian Particle Transport In Turbulent Flows, Guangyuan Sun Dec 2015

Stochastic Simulation Of Lagrangian Particle Transport In Turbulent Flows, Guangyuan Sun

Theses and Dissertations

This dissertation presents the development and validation of the One Dimensional Turbulence (ODT) multiphase model in the Lagrangian reference frame. ODT is a stochastic model that captures the full range of length and time scales and provides statistical information on fine-scale turbulent-particle mixing and transport at low computational cost. The flow evolution is governed by a deterministic solution of the viscous processes and a stochastic representation of advection through stochastic domain mapping processes. The three algorithms for Lagrangian particle transport are presented within the context of the ODT approach. The Type-I and -C models consider the particle-eddy interaction as instantaneous …

“I Take--No Less Than Skies”: Emily Dickinson And Nineteenth-Century Meteorology, Kjerstin Evans Ballard Dec 2015

“I Take--No Less Than Skies”: Emily Dickinson And Nineteenth-Century Meteorology, Kjerstin Evans Ballard

Theses and Dissertations

Emily Dickinson's poetry functions where scientific attention to the physical world and abstract theorizing about the ineffable intersect. Critics who emphasize the poet's dedication to the scientific often take for granted how deeply the uncertainty that underlies all of Dickinson's poetry opposes scientific discussion of the day. Meteorology is an exceptional nineteenth-century science because it takes as its subject complex systems which are inexplicable in Newtonian terms. As such, meteorology can articulate the ways that Dickinson bridges the divide between the unknown and the known, particularly as she relates to the interplay of nature and culture, the role of careful …

A Longitudinal Examination Of The Effects Of Acculturation And Mental Health Problems On Immigrant Father Involvement: A Cross-Cultural Study, Keitaro Yoshida Dec 2015

A Longitudinal Examination Of The Effects Of Acculturation And Mental Health Problems On Immigrant Father Involvement: A Cross-Cultural Study, Keitaro Yoshida

Theses and Dissertations

The present study examined how acculturation, mental health problems, and parenting stress are associated with two dimensions of father involvement longitudinally for Latino and Chinese immigrant fathers using a nationally representative sample of young children and their resident fathers from the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B). After controlling for a variety of individual and demographic characteristics and previous levels of father involvement, results from multiple group structural equation modeling revealed that immigrant fathers' English proficiency is negatively associated with care-taking involvement at 2 years, but positively associated with care-taking involvement at 4 years. Interestingly, mothers' English proficiency is also …

Blockade Of Tgf-Ss Signaling Through The Activin Type Iib Receptor With The Small Molecule, Sgi-1252, Jordan David Fuqua Dec 2015

Blockade Of Tgf-Ss Signaling Through The Activin Type Iib Receptor With The Small Molecule, Sgi-1252, Jordan David Fuqua

Theses and Dissertations

Antagonism of the activin receptor signaling pathway represents a promising potential therapy for the muscular dystrophies and other muscle wasting disorders (i.e., cachexia or sarcopenia). Previous research has shown that antagonism of activin signaling promotes muscle growth, attenuates muscle wasting, and restores function in both wild type and diseased animals. Our laboratory has recently developed a novel small molecule (SGI-1252) that inhibits activin downstream (i.e., Smad2/3 phosphorylation) signaling. Purpose: In this study we determined how eight weeks of orally administered SGI-1252 affected TGF-ß signaling, whole body mass, individual limb muscle mass, and muscle fiber cross sectional area (CSA). Methods: Wild-type …

The Effect Of Aerobic Exercise Versus Inactivity On Nitric Oxide Concentration And Synthesis In An Elderly Population, Samantha Burton Dec 2015

The Effect Of Aerobic Exercise Versus Inactivity On Nitric Oxide Concentration And Synthesis In An Elderly Population, Samantha Burton

Theses and Dissertations

CONTEXT: Nitric Oxide (NO) is an endothelial-derived vasoactive molecule that causes an increase in blood flow and oxygen delivery to tissue. A reduction in NO bioavailability has been found to occur in adults over the age of 60 and can be reversed pharmacologically by improving NO synthase (NOS) activity. Reversing these age-related changes with alternative interventions, such as aerobic exercise, has shown some promising results. OBJECTIVE: To quantify blood NO-bioavailability (as measured by blood nitrite levels) in a population of aerobically trained elderly men and compare these data to a group of age-matched, inactive individuals. In addition, we measured the …

Water Use Of Four Commonly Planted Landscape Tree Species In A Semi-Arid Suburban Environment, Michael Cameron Bunnell Dec 2015

Water Use Of Four Commonly Planted Landscape Tree Species In A Semi-Arid Suburban Environment, Michael Cameron Bunnell

Theses and Dissertations

Native plant communities and agricultural land are commonly converted to urban areas as cities across the Western United States continue to grow and expand. This expansion is typically accompanied by afforestation where a common goal among communities is to maximize shade tree composition. Planted forests in these regions are commonly composed of introduced tree species native to mesic environments and their ability to persist is dependent on consistent irrigation inputs. Many potential ecosystem services may be derived from planting trees in urban and suburban areas; however, there are also costs associated with extensive afforestation, and shade tree cover may have …

Virulence Of Photorhabdus Spp.: Examining The Roles Of Environment, Evolution, And Genetics In Insect Mortality, Dana Blackburn Dec 2015

Virulence Of Photorhabdus Spp.: Examining The Roles Of Environment, Evolution, And Genetics In Insect Mortality, Dana Blackburn

Theses and Dissertations

Entomopathogenic nematodes (EPNs) (genera Heterorhabditis and Steinernema) kill their invertebrate hosts with the aid of a mutualistic bacterium. The bacteria (Xenorhabdus spp. for steinernematids and Photorhabdus spp. for heterorhabditids) are primarily responsible for killing the host and providing the nematodes with nutrition and defense against secondary invaders. Photorhabdus is a Gram-negative bacterium in the Enterobacteriaceae family with high virulence towards their insect hosts. To achieve high mortality rates Photorhabdus produces a variety of virulence factors such as toxins, lipases, proteases, secretion systems, and fimbriae. EPNs are amenable to laboratory rearing and mass production for biocontrol applications against insects …

Hand-Portable Capillary Liquid Chromatography Instrumentation, Sonika Sharma Dec 2015

Hand-Portable Capillary Liquid Chromatography Instrumentation, Sonika Sharma

Theses and Dissertations

This dissertation focuses on the development of hand-portable capillary liquid chromatography (LC) instrumentation. In this work, battery-operable nano-flow pumping systems (isocratic and gradient) were developed and integrated with portable UV-absorption detectors for capillary LC. The systems were reduced in size to acceptable weights and power usage for field operation. A major advantage of the pumps is that they do not employ a splitter, since they were specifically designed for capillary column use, thereby greatly reducing solvent consumption and waste generation. UV-absorption detectors were specifically designed and optimized for on-column detection to minimize extra-column band broadening. Initially, an isocratic nano-flow pumping …
