A Behavioral Model Of Law Enforcement Applicant Characteristics Derived From A Simulated Cheating Task: Implications For Pre-Employment Hiring Practices, Julian Montaquila

Electronic Theses and Dissertations

Recently, numerous high-profile instances of police misconduct and corruption have been thrust into the national spotlight. Hiring police officers who will act with integrity and not betray public trust remains essential. The present research experimentally examines this phenomenon by evaluating pre-employment assessment results against applicant performance on a simulated cheating task (i.e., The Dots Task) in order to derive information to improve contemporary pre-employment screening and selection models. Four case examples are presented which depict malicious actors who possessed privileged access, assumed no one would ever scrutinize their activities, and attempted to leverage a lack of oversight for their personal …

Boitawl: Soil, Lost And Left, Bishnupriya Chowdhuri

Electronic Theses and Dissertations

Boitawl ("Boi"- lack, devoid of, "Tawl"- bottom/ ground/ foundation), the word in one of the Bengali dialects refers to one without a ground beneath her feet. The thesis, a hybrid collection of prose and verse including narratives and graphic vignettes, flash, fabulist and short stories, prose poems and free verse imagines the inside worlds of such un-settled existences. In the process, the pieces connect migration, memory, childhood and lost towns with fractured humans caught in between - to reveal what lies under pillars of desires, the shapes of unsaid longings and recurrent images in their dreams.

Selective Carbon-Carbon Bond Formation Promoted By Divalent Samarium Reagents, Christopher David-James Aretz

Electronic Theses and Dissertations

Three efficient methods for synthesis of five membered carbocycles, a highly understudied product motif in samarium(II) chemistry, were explored and optimized. These methods utilized simple starting materials to generate linear substrates with functional groups that are reactive towards samarium(II) iodide. The three methods explored were the Reformatsky-aldol, Reformatsky-alkylation, and pinacol cyclizations. The critical discovery for efficient formation of the Reformatsky-aldol and pinacol carbocycles products was the use of lithium bromide. This addition of lithium bromide facilitates easy in situ formation of samarium(II) bromide. The Reformatsky-alkylation cyclization was a newly realized reaction employing samarium enolates. Two of the three methods, the …

The Sasquatch is incredibly popular in American society. This project explores the impact of the Sasquatch phenomenon on those that live in and visit Bailey, Colorado. It focuses on how the Sasquatch Outpost museum contributes to this impact, especially through outdoor activities, visiting the museum, visiting the Outpost general store, and the sharing of sighting stories. This work takes an in-depth look at the concept of the amateur museum, or micromuseum, and how it can contribute to the larger museum world, particularly through the ideas of Outsider Art and serious leisure. By evaluating the processes, exhibits, and procedures of the …

Weathering Climate Change: Provisions For Climate Change Resiliency In Transboundary River Treaties, Emily Joan Zmak

Electronic Theses and Dissertations

Climate change will be most apparent in alterations to the hydrologic system - shifts in movement, variations in extremes - thereby defining many resource disputes in the coming decades. Water is a boundaryless resource; as its hydrologic patterns shift within and without borders, so too will preexisting agreements on its use and allocation. The question for transboundary water agreements is: how can agreements both satisfy parties' needs and account for future uncertainties of climate-induced changes to their basins' hydrologic systems?

From examining literature and water agreements, this thesis develops a list of provisions identified as foundational to resiliency in transboundary …

Using Dialogue To Interrupt Legacies Of Exclusion, Incite Hope, Invite Change, And Increase Levels Of Awareness At Predominantly White Institutions With Diversity, Equity, And Inclusion Rhetoric, Amanda Meise

Electronic Theses and Dissertations

This dissertation questions how a predominantly white institution (PWI) could infuse dialogue to aid the implementation of diversity, equity, and inclusion (DEI) initiatives and invite institutional change. There has been an increased spotlight on racial tensions permeating predominantly white campuses with DEI initiatives; higher education scholars have identified several factors that prevent institutions from fostering inclusive spaces. This research addresses three specific hurdles for PWIs implementing DEI initiatives: (1) social amnesia characterized by romanticized versions of history; (2) a discontinuity between professed values and the goals of DEI initiatives with policy, structure, and experience; and (3) low awareness of privilege …

Whither The Gender Of Get Out: A Critique Of The Cinematic (Im)Possibilities Of The Black Political Imagination, Daelena Tinnin

Electronic Theses and Dissertations

This thesis investigates the entanglements of spatialized racial-sexual violence, conceptualizations of black female subjectivity, questions of the limitations and excesses of media representations and the socioeconomic, cultural and spatiotemptoral relations that make black images visible and (im) possible as they are situated in the cinematic black political imagination. Through a materialist media analysis of the 2017 film Get Out, I argue that the film and its articulation of the afterlife of slavery fails to account for gender by tangentially engaging black women in its dissection of race and racism. I contend that black women are the absent presence in …

Paleoflood Hydrology And Basin Morphometric Characteristics Related To Flooding In The Colorado Front Range, Natalie Trivino

Electronic Theses and Dissertations

Flooding hazards are common in the Colorado Front Range due to the steep, complex terrain of the mountains where waters quickly spill out onto the most populated region of Colorado. This region has experienced numerous catastrophic floods, such as the 2013 Front Range Floods, the Fort Collins Flood of 1997, and the Big Thompson Canyon Flood of 1976 to name a few. The objective of this study was to analyze basin morphometric characteristics of several drainage basins throughout the Colorado Front Range South Platte River tributaries and determine how these characteristics relate to extreme flooding. This was done through three …

Symmetry Identified In 2-Dimensional Artwork Compositions Using Visuospatial Ability, Theresa Ferg

Electronic Theses and Dissertations

At the John Langdon Down Foundation A.C. in the La Escuela Mexicana de Arte Down school in Mexico City D.F., Mexico, art students with Trisomy 21 display the use of a mathematical construct in the painting compositions of their artworks. The mathematical construct is a type of symmetry and it carries a positive affect. This is important because there have been no studies that have investigated the use of the symmetry in the artwork compositions of persons with Down syndrome. The geometric construction of the artwork compositions follows the artistic principle of the Rule of Three and the division of …

Origins Of Animal Cell Adhesion, Jennyfer Mora Mitchell

Electronic Theses and Dissertations

A fundamental requirement for multicellularity is cell adhesion. This includes mechanisms by which cells adhere to each other and to their secreted extracellular matrix (ECM). Two well characterized adhesion complexes in animals include: 1) adherens junctions (AJs), which are involved in cell-cell adhesion and composed of cadherin receptors, p120-, α- and β-catenin, and 2) focal adhesions (FAs), which are involved in cell-ECM adhesion and include proteins such as integrins, vinculin, paxillin, talin and focal adhesion kinase (FAK). The molecular components of AJs are widely conserved in animals, and largely absent in non-animals. In contrast, the molecular components of FAs have …

An Investigation Of The Performance Of Urban Rail Transit Systems On The Corridor Level: A Comparative Analysis In The American West, Daniel Zimny-Schmitt

Electronic Theses and Dissertations

Since the 1980s, significant investments have been made in urban rail transit across the United States, particularly using light rail technology. Most of these light rail systems have been built in Sunbelt cities which no longer had legacy rail systems. As a result, they were constructed using a building blocks approach, being funded corridor by corridor. Most research, however, on urban rail performance has taken place at the system-wide level, leaving a significant gap at the level of the transit corridor. This research examined nineteen urban rail corridors in Denver, Salt Lake City, and Portland. A performance score was constructed …

Life Partner Perceptions Of The Emotional Impact Of Stuttering, Athanasia Svenning

Electronic Theses and Dissertations

The aim of the present study is to investigate the extent to which life partners understand the emotional impact stuttering has on their loved one who stutters. This was accomplished by administering the Speech Situation Checklist - Emotional Reaction (SSC-ER), a subtest of the Behavior Assessment Battery (BAB; Vanryckeghem & Brutten, 2018) via Qualtrics, an online survey software, to the participants who stutter and a modified version of the SSC-ER to their life partner. No significant differences and a positive correlation were observed between groups (people who stutter (PWS) and their life partner (LP) as it relates to total score …

Improving The Detection Limit Of Tau Aggregates For Use With Biological Samples, Emily Rickman Hager

Electronic Theses and Dissertations

The protein Tau is found in neurofibrillary tangles in Alzheimer's disease and over 20 other neurodegenerative diseases. An assay has been developed to detect minute amounts of fibrils from human brain tissue. This assay subjects brain tissue extract and recombinant Tau to several rounds of sonication and incubation. Incubation allows recombinant Tau to add itself to the ends of the existing fibrils in brain tissue extract. Sonication breaks the existing fibrils in the brain tissue extract offering more ends for Tau to add onto. Cycles of sonication and incubation have been shown to allow for amplification of Tau fibrils from …

"Traditioning" Blackness: A Theo-Ethical Analysis Of Black Identity In Black Theological Discourse, Ben Sanders Iii

Electronic Theses and Dissertations

The emergence of James Cone's black liberation theology in the late-1960s and early 1970s marked both a radical challenge to and a historical transformation of the fields of religious and theological studies. Building on Cone's work, black theological discourse has developed a rich tradition of religious and academic inquiry characterized by its commitment to interpreting Christianity in particular, and religious experience more broadly, from the vantage point of oppressed black people. This dissertation shows that James Cone developed a particular understanding of black identity in his early works and, furthermore, that various scholars have critically engaged this conception of black …

Relationship Between Tdp-43 Toxicity And Aggregation In Saccharomyces Cerevisiae, Martin Anthony Aguilar

Electronic Theses and Dissertations

Protein aggregation and inclusion body formation are hallmarks of neurodegenerative diseases such as Alzheimer's, Parkinson's, Huntington's, and amyotrophic lateral sclerosis (ALS). These neurodegenerative diseases share a common pathology in that all include accumulation of insoluble protein aggregates in the brain. TAR-DNA-binding protein (TDP-43) is the major component found in the pathological inclusions of two of these diseases, ALS and frontotemporal lobar degeneration with ubiquitin-positive inclusions (FTLD-U). This thesis focuses upon the biophysical basis for TDP-43 aggregation in S. cerevisiae. Current in vitro evidence indicates that TDP-43 is a natively dimeric protein and that binding to RNA inhibits aggregation. Corresponding …

A Descriptive Policy Analysis Of State-Level Universal Preschool Adoption, Holly Higgins Wilcher

Electronic Theses and Dissertations

Presently, the United States does not have a publicly funded, comprehensive, universal ECE system. The fragmented and piecemeal approach to providing ECE creates social injustice and inequity for many young children (Kagan & Roth, 2017; Kagan, 2009). With the absence of comprehensive and streamlined federal ECE policy, several states have attempted to at least provide universal preschool to all four-year-old children. For states that aim to adopt universal preschool, it is critical to understand the factors, political conditions, and policy environments conducive to creating preschool policy change. Although many states would like to provide universal preschool, very few have been …

Photochemistry Of Polycyclic Aromatic Hydrocarbons With Environmentally Relevant Metals, John P. Haynes

Electronic Theses and Dissertations

The details of the work presented in this dissertation focus on simulated reactions in the atmosphere and water systems between persistent aromatic compounds and varying species of metals with an emphasis on iron. Bulk water suspensions of a standard soil and polycyclic aromatic hydrocarbons (PAH) were analyzed for soluble iron by inductively-coupled plasma mass spectroscopy (ICP-MS) following a 16 hour reaction period using simulated sunlight. Significant increases in soluble iron were only seen with 2-3 ring linear PAH and carboxylic acids.

A two-stage study was conducted to investigate the potential for and possible mechanisms involving the photo-oxidation of PAH into …

National Interests And Security Policies In The Arctic Region Among Arctic States, Hilde-Gunn Bye

Electronic Theses and Dissertations

The United States, Canada, Russia, and Norway are all Arctic states; however, they prioritize the region to different degrees in terms of investments of security assets and military presence. What explains why some Arctic countries prioritize the Arctic more than others? This thesis explores this question through using an issue-based approach, which looks at the salience of issues as having implications for foreign policy tools and measures. This thesis finds that having interests and stakes in the region of high overall salience contribute to an explanation of why some countries prioritize the region more, while low overall salience is linked …

The Power Of Resurrection: Early Christian Resistance Through The Rise Of Disciplinary Power, Patrick G. Stefan

Electronic Theses and Dissertations

This dissertation is an analysis of the spread of Christianity in the first three centuries and the commensurate activation and development of what Michel Foucault calls disciplinary mechanisms of power. It sets out to explore two questions, first, what were the theoretical conditions that led to Christianity's rapid expansion? And second, what were the historical precursors to the mechanisms of disciplinary power? It then seeks to put these two questions together to propose that early Christianity was successful in overtaking the Roman Imperial government because it activated underlying disciplinary mechanisms of power in a world governed and controlled by sovereign …

The main research question guiding this study was: What factors support or constrain the academic resiliency of Newcomers? The purpose of this study was to examine the academic resilience of Newcomers at an urban high school in Colorado. This qualitative study utilized case study methods of data collection. This study took place in four stages. The first stage encompassed …

Superresolved Three-Dimensional Analysis Of The Spatial Arrangement Of The Human Immunodeficiency Virus Type-1 (Hiv-1) Envelope Glycoprotein At Sites Of Viral Assembly, Carmen Anne Buttler

Electronic Theses and Dissertations

Human Immunodeficiency Virus type 1 (HIV-1) replicates by forcing infected host cells to produce new virus particles, which assemble form protein components on the inner leaflet of the host cell's plasma membrane. This involves incorporation of the essential viral envelope glycoprotein (Env) into a structural lattice of viral Gag proteins. The mechanism of Env recruitment and incorporation is not well understood. To better define this process, we seek to describe the timing of Env-Gag encounters during particle assembly by measuring angular positions of Env proteins about the surfaces of budding particles. Using three-dimensional superresolution microscopy, we show that Env distributions …

Living Through Terror And Terror Through Living: The Biopolitical Dimensions Of Religion, Security, And Terrorism, Donnie Featherston

Electronic Theses and Dissertations

Recent emphasis and attention by thinkers, media pundits, and politicians on terrorism requires new, critical evaluation of the processes by which terrorism is understood. By investigating the concept of biopolitics, as developed specifically through Michel Foucault and Giorgio Agamben, new insights into the interactions between terrorism, politics, and religion can emerge. Most notably, the attempts to explain terror as simply an economic problem, an excessive form of violence, and/or as religious fervency gone awry rely on embedded biopolitical concepts. The continual attempts to solve terrorism through increased biopolitical strategies, thereby making terrorism a problem for biopolitics, only further substantiate the …

Rethinking Reintegration And Veteran Identity: A New Consciousness, Jeni Hunniecutt

Electronic Theses and Dissertations

This dissertation explores how Veteran reintegration is a process of identity transformation. Written as a first-person narrative and weaving my own story of Veteran reintegration and identity into the chapters, this purpose of this project is to address two questions: RQ1: Examining my own experiences of separating from the U.S. Military institution, what are some possible Veteran identity tensions that exist in the liminal space of reintegration? And, RQ2: How might the experiences of U.S. Military Veteran reintegration be shaped by an individual's sacred liminal experience of military initial entry training as well as their institutionalized liminal experience of belonging …

The Investigation Of Lactoferrin Nitration: Quantification, Function, And Inhibition, Amani Yahya Alhalwani

Electronic Theses and Dissertations

Lactoferrin (LF) is an iron-binding glycoprotein of molecular mass ca. 80 kDa that is predominantly found in mammalian body fluids. Lactoferrin is a multifunctional protein that has a wide range of properties such as antibacterial, antiviral, anti-inflammatory, and anti-allergic functions. Tyrosine residues in the protein play a part in many lactoferrin functions. Protein tyrosine nitration modification represents an oxidative and nitrosative stress process which can be caused by the exposure of proteins to oxidants from air pollution or disease. Understanding the way nitrated lactoferrin interacts with the biochemical environment of the body is thus important to the broader goal of …

Adolescent Protective Factors Related To Resilience: Issues Of Academic Self-Efficacy, Parental Involvement, And Special Education Status, Bethdalie Cruz

Electronic Theses and Dissertations

The predictive value of three constructs was examined in this study in order to explain adolescent self-reported protective factors associated with resilience while moderating for the effects of sex and race. The three constructs included Academic Self-efficacy, Maternal Parental Involvement, and Special Education Identification Status. Participants included 54 adolescents in diverse public middle and high schools, ages 11 to 18. Twenty of these participants were identified as receiving special education services while 34 did not. Results indicated that adolescent perceptions of Academic Self-efficacy significantly predicted protective factors associated with resilience while Special Education Identification Status and Maternal Parental Involvement did …

A History Of Nondenominational Churches In Denver And Beyond, 1945–2000, R. Norton Herbst

Electronic Theses and Dissertations

From 1945-2000, nondenominational churches in America developed from a scattering of independent congregations to one of the largest groups of churches in the nation. Few scholars have studied these churches as a cohesive movement. And many think they burst onto the American scene around the 1990s, though statistics suggest otherwise. Two questions, therefore, need to be addressed: What is the historical genealogy of nondenominational churches in modern America? And, is there a recognizable nondenominational church identity?

This study explores these questions in three ways. First, I survey the origins and development of Protestant denominationalism from the Reformation through the early …

Creating A Consistent Oceanic Multi-Decadal Intercalibrated Tmi-Gmi Constellation Data Record, Ruiyao Chen

Electronic Theses and Dissertations

The Tropical Rainfall Measuring Mission (TRMM), launched in late November 1997 into a low earth orbit, produced the longest microwave radiometric data time series of 17-plus years from the TRMM Microwave Imager (TMI). The Global Precipitation Measuring (GPM) mission is the follow-on to TRMM, designed to provide data continuity and advance precipitation measurement capabilities. The GPM Microwave Imager (GMI) performs as a brightness temperature (Tb) calibration standard for the intersatellite radiometric calibration (XCAL) for the other constellation members; and before GPM was launched, TMI was the XCAL standard. This dissertation aims at creating a consistent oceanic multi-decadal Tb data record …
