Satellite Remote Sensing Of Active Wildfires In Alaska's Boreal Forest, Christine F. Waigl

Geosciences

This research addresses improvements to the detection and characterization of active wildfires in Alaska with satellite-based sensors. The VIIRS I-band Fire Detection Algorithm for High Latitudes (VIFDAHL) was developed and evaluated against existing active fire products from the Visible Infrared Imaging Radiometer Suite (VIIRS) and the Moderate Resolution Imaging Spectroradiometer (MODIS). This new algorithm is based on VIIRS 375 m spatial resolution imagery and was tuned using fires in Alaska's boreal forest. It provides improved fire detection of low-intensity fires, especially during daytime and at sensor zenith angles smaller than approximately 50° off nadir. Low-intensity active fires, which represent residual …

Phylogeography And Molecular Phylogenetics Of The Hoary Marmot (Marmota Caligata), Nicholas John Kerhoulas

Biological Sciences

In this dissertation I documented the phylogeographic history of the Hoary Marmot (Marmota caligata) and its phylogenetic relationships with the Vancouver Island (M. vancouverensis) and Olympic (M. olympus) marmots. The Hoary Marmot is an iconic alpine mammal that is broadly distributed throughout the Pacific Northwest (PNW) from Washington and central Idaho in the south to Alaska in the north. Vancouver Island and Olympic marmots have much more restricted geographic distributions, occurring only on Vancouver Island (British Columbia, Canada) and the Olympic Peninsula (Washington, USA), respectively. In my first chapter I used mitochondrial DNA (mtDNA) sequence data to document the existence …

Assessing Seasonal Trends In Harbor Seal (Phoca Vitulina) Diet Using Stable Isotope Analysis Along The Whisker, Justin Arthur Smith

Biological Sciences

Harbor seals (Phoca vitulina) that use tidewater glaciers in the summers to molt, pup, and breed have declined in recent years, which could be attributed to reduced prey availability caused by regime shifts in the coastal marine environment. Recording seasonal dietary trends of harbor seals in different years could improve our ability to test if regime shifts caused these declines. However, such analysis has not been possible, because wild harbor seals are difficult to recapture. Stable isotope analysis of serial sections of growing whiskers (mystacial vibrissae) can be used as a tool to assess diet over different seasons, but uncertainty …

Social-Ecological Soundscapes: Examining Aircraft-Harvester-Caribou Conflict In Arctic Alaska, Taylor R. Stinchcomb

Biological Sciences

As human development expands across the Arctic, it is crucial to carefully assess the impacts to remote natural ecosystems and to indigenous communities that rely on wild resources for nutritional and cultural wellbeing. Because indigenous communities and wildlife populations are interdependent, assessing how human activities impact traditional harvest practices can advance our understanding of the human dimensions of wildlife management. Indigenous communities across Arctic Alaska have expressed concern over the last four decades that low-flying aircraft interfere with their traditional harvest practices. For example, communities often have testified that aircraft disturb caribou (Rangifer tarandus) and thereby reduce harvest opportunities. Despite …

Cultural Differences In Group Therapy: A Phenomenological Study Of The Lived Embodied Experience Of The Cultural Bump, Natalie R. Breitmeyer

Creative Arts Therapies Theses

Utilizing transcendental phenomenology, this study sought to better understand dance/movement therapists’ experiences of the culture bump phenomenon in the group therapy setting. Culture bumps are defined as moments in which two or more people enter a situation with different culturally-based expectations about customs, behavior, beliefs, communication styles, and other norms (Archer & Nickson, 2012). Data were collected using individual inperson semi-structured interviews with five Chicagoland dance/movement therapists who self identified as having experienced the phenomenon of the culture bump while in the group therapy setting. Data analysis was completed using Moustakas’ (1994) adaptation of the Stevick-Colaizzi-Keen method and resulted in …

Parental Perceptions On The Impact Of Adhd Medication Regarding Children’S Inappropriate Behavior And Academic Performance, Amy Vest

CUP Ed.D. Dissertations

Centers for Disease Control and Prevention (2014) suggested that parenting a healthy child brings about a variety of challenges throughout life, however parenting a child diagnosed with Attention Deficit Hyperactive Disorder (ADHD) proves a daunting task inundated with unanswered questions and multitudes of stressful situations. The purpose of this research is to study parent perceptions of a child’s ADHD medication to determine if a relationship exists between the ADHD medication, inappropriate behavior and academic performance. The quantitative survey instrument provided the means to examine the significance of the child’s ADHD medication on one day of the parent’s choice within the …

Setting:Home, Adrienne Cole

CGU MFA Theses

I look at the world graphically, seeing people as objects, objects as shapes and shapes as lines. I develop these elements into textural abstractions and patterned representations. Sometimes my work is almost entirely abstract while at other times traces of visual references can be seen. I am interested in intersections and in-between; my works fill space with disorder allowing the audience to see through my scattered, confusing and often times mysterious lens.

Preventing Obesity And Cardiovascular Disease In At-Risk Youth, Allison Patricia Woolf, Nicole Ashley Bauernfeind, Rachel Katharine Civale, Elizabeth Rose Spellman

Senior Honors Projects, 2010-2019

The literature review that was conducted focuses on exploring the most effective way to prevent development of Cardiovascular Disease (CVD) as a late effect of childhood obesity or risk thereof. Our research focused on the 8-10 year old at-risk and obese pediatric populations and whether the use of interactive educational interventions in the community setting can be of use to reduce CVD development and improve overall health status. Our findings determined that interactive educational interventions early in childhood can improve health outcomes for these populations and prevent subsequent development of CVD. We minimized the inclusion of all research whose evidence …

The Role Of Brain Stem 5-Ht1a And Gaba-A Receptors In The Thermoregulatory Response To Hypoxic Stress, Alexander Schmidt

Senior Honors Projects, 2010-2019

Sudden Infant Death Syndrome (SIDS) is a leading cause of infant mortality. Alterations in brainstem development of Serotonin (5HT) and γ-aminobutyric acid (GABA) are linked to its cause. The sympathetic premotor neurons located in the Nucleus of the Raphe Pallidus (NRP) in the brainstem have both 5-HT1A and GABA-A receptor subtypes that mediate protective cardiovascular responses to environmental stress. It is hypothesized that alteration in these receptors at the NRP will also modify protective thermoregulatory responses to hypoxic stress such as hypothermia. Using aseptic techniques, male and female Sprague-Dawley rats (230-385g) were instrumented with radiotelemetry probes to non-invasively measure core …

Tetrameric Structure Of Beta-Amylase 2 (Bam2) In Arabidopsis Thaliana, Lauren Elizabeth Pope

Senior Honors Projects, 2010-2019

Plants store starch during the day for use at night. This process of transitory starch degradation is mostly attributable to the β-Amylase (BAM) family, which are starch exohydrolases that cleave the penultimate α-1,4 glycosidic bonds of starch to release maltose. BAM2 was recently characterized as a catalytically active, K⁺-requiring tetramer with sigmoidal kinetics and cooperativity. All other catalytically active BAMs display Michaelis-Menten kinetics, no cooperativity, and do not require salt, making BAM2’s characteristics intriguing. Due to a lack of a crystal structure, a monomeric homology model of BAM2 was generated using I-TASSER based on a BAM5 from soybean. …

Using Social Narratives To Improve The Healthcare Experiences Of Children Diagnosed With Autism Spectrum Disorder, Margaret Spindel

Senior Honors Projects, 2010-2019

Children with Autism Spectrum Disorder (ASD) often experience significant emotional stress when they visit a healthcare provider. The focus of this research project was to explore the use of social narratives to help reduce stress associated with this environment. Social narratives are short stories designed to walk a child through a potential situation that they will encounter, that they may not be familiar with, or that they are not currently handling properly. As part of an initial literature review, evidence for the need for additional intervention in the healthcare setting for children with ASD was established. Continuing literature review then …

Navigating Culture: An Exploration Of Domestic Violence And Abuse Resource Provision To The Harrisonburg Iraqi Refugee Community, Kaitlin Michelle Holland

Senior Honors Projects, 2010-2019

There are currently 22.5 million refugees worldwide who have been displaced from their home countries due to war, conflict, or persecution. Of this total, only 1% are recommended for resettlement each year. In recent years, many of these resettled refugees have come from Iraq, fleeing conflict stemming from the Iraq war and ISIS. Upon resettlement, refugees face significant acculturation difficulties that can negatively affect mental health. Additionally, experiencing domestic violence and abuse (DVA) can also negatively affect physical and mental health. I researched how the refugee migration experience and domestic violence and abuse affect mental health as well as what …

Lipophosphoglycan Polymorphisms Do Not Affect Leishmania Amazonensis Development In The Permissive Vectors Lutzomyia Migonei And Lutzomyia Longipalpis, Paula M. Nogueira, Agna C. Guimarães, Rafael R. Assis, Jovana Sadlova, Jitka Myskova, Katerina Pruzinova, Jana Hlavackova, Salvatore J. Turco, Ana C. Torrecilhas, Petr Volf, Rodrigo P. Soares

Molecular and Cellular Biochemistry Faculty Publications

Background: Lipophosphoglycan (LPG) is a dominant surface molecule of Leishmaniapromastigotes. Its species-specific polymorphisms are found mainly in the sugars that branch off the conserved Gal(β1,4)Man(α1)-PO₄ backbone of repeat units. Leishmania amazonensis is one of the most important species causing human cutaneous leishmaniasis in the New World. Here, we describe LPG intraspecific polymorphisms in two Le. amazonensis reference strains and their role during the development in three sand fly species.

Results: Strains isolated from Lutzomyia flaviscutellata (PH8) and from a human patient (Josefa) displayed structural polymorphism in the LPG repeat units, possessing side chains with 1 and 2 β-glucose …

Small-Animal Models Of Zika Virus, Justin G. Julander, Venkatraman Siddharthan

Animal, Dairy, and Veterinary Science Faculty Publications

Zika virus (ZIKV) infection can result in serious consequences, including severe congenital manifestations, persistent infection in the testes and neurologic sequelae. After a pandemic emergence, the virus has spread to much of the new world and has been introduced to many countries outside of endemic areas as infected travelers return to their home countries. Rodent models have been important in gaining a better understanding of the wide range of disease etiologies associated with ZIKV infection and for the initial phase of developing countermeasures to prevent or treat viral infections. We discuss herein the advantages and disadvantages of small animal models …

Common Goods In Uncommon Times: Water, Droughts, And The Sustainability Of Ancestral Pueblo Communities In The Jemez Mountains, New Mexico, Ad 1100-1700, Michael Aiuvalasit

Anthropology Theses and Dissertations

Adapting our infrastructure and institutions to climate change is a crucial dilemma for modern society. Archaeologists should be well positioned to address this issue with examples from the past. Yet, too often when we find that cultural changes are synchronous with climate variation, such as abandonment of a region during a drought, we advance causal arguments to what may merely be correlations. I argue that identifying proxies for resource management in the archaeological record, particularly for resources managed by collective action and vulnerable to climate change, can help to address this problem. To test this approach I studied water management …

Quantum Chemical Studies Of Noncovalent Interactions And Multicenter Bonds Utilizing Local Vibrational Modes, Vytor Oliveira

Chemistry Theses and Dissertations

Noncovalent interactions play an important role for the design of novel drugs, better catalysts, synthesis of complex supramolecular structures, and so on. To develop new materials, a well-founded knowledge of how to control the strength of these interactions is desirable. Despite the many investigations done so far, a quantitative assessment of the intrinsic strength of most types of noncovalent interactions is still missing. Recently and for the first time, the Konkoli-Cremer local modes analysis was successfully used to probe the intrinsic strength of hydrogen and pnicogen bonds. We extended these investigations to more than 300 halogen and chalcogen bonds. A …

Pathological Personality Traits And Neuropsychological Function, Rui Tang

Psychology Theses and Dissertations

Traditional categorical diagnosis in DSM-5 has received widespread criticism due to its extreme heterogeneity, poor diagnostic reliability, poor validity and high comorbidity. The alternative trait model introduced the domain of psychoticism, which captures the trait of positive schizotypy. Positive schizotypy has been linked to vulnerability to schizophrenia spectrum disorders, which has shown several areas of neuropsychological dysfunction. Considerable evidence has demonstrated that the dimensional model has superior reliability and validity and ties to important clinical constructs such as neuropsychological function. Little research has tied the dimensional model of personality pathology to neuropsychological domains including processing speed and executive function. The …

African-American Males, Part-Time Work, And Persistence, Ami M. Tripp

CUP Ed.D. Dissertations

The central research question for this study asked how do African-American males perceive working part-time, while enrolled full-time, to have an impact on their persistence? A secondary question asked, what factors influenced African-American male students to persist through graduation? The participants comprised of 35 African-American male college students who graduated Spring 2016. This study was focused on part-time employment and its support of persistence for African-American men. Hence, persistence theory was the most pertinent lens through which to view the literature and the data collected in this study. This study employed a case study research, as it is an empirical …

Dual Enrollment And Rural Alaska: A Qualitative Case Study Examining Student Access And Impact, Corey S. Weiss

CUP Ed.D. Dissertations

This case study employed an interview process that examined the access rural Alaskan students have to dual enrollment and how it differs from the access of similar school districts in remote areas of Texas. The interviewees consisted of administrators of five school districts in northern and western Alaska and their counterparts in districts in western Texas. The outcome of this study is relevant to dual enrollment research as it provides more data from a region that has been overlooked by researchers and establishes that the school districts have a substantial degree of access to dual enrollment, with no significant differences …

The Mediating Role Of Trauma Symptoms In Teen Dating Violence Victimization, Caitlin Rancher, Ernest Jouriles, Renee Mcdonald, Jeff Temple, David Rosenfield

Psychology Theses and Dissertations

This research examined whether the frequency of recent physical and sexual teen dating violence (TDV) victimization is associated with re-experiencing, avoidance, and hyperarousal trauma symptoms, and whether they, in turn, predict the frequency of future TDV victimization. Participants were 104 (49% female) 14 to 17 year olds, recruited primarily from truancy courts to participate in three assessments, spaced three months apart. Adolescents reported on their trauma symptoms, experiences of physical and sexual dating violence victimization and characteristics of their romantic relationship at every assessment. Results indicated that the frequency of recent TDV victimization is related to re-experiencing, avoidance and hyperarousal …

Micro-Architectured Metamaterials: Design And Analysis, Li Ai

Mechanical Engineering Research Theses and Dissertations

Metamaterials are engineered materials with unusual properties deriving mainly from their micro-architectures rather than composition. They have attracted increasing attention owing to their tailorable multi-functional properties that cannot be exhibited by naturally-occurring or traditionally-manufactured materials. Materials with a negative Poisson’s ratio (PR) and materials with a non-positive coefficient of thermal expansion (CTE) are examples of mechanical metamaterials. In this dissertation, metamaterials with negative Poisson’s ratios and negative coefficients of thermal expansion are designed using both heuristic approaches and topology optimization methods.

Firstly, based on a star-shaped re-entrant structure, three two-dimensional (2-D) periodic cellular materials are developed, which can be tailored …
