How Chicago Public Schools Engaged African American Parents In The Closing Of Austin Career Academy High School, Shani Blackwell

Master's Theses

The role of African American parents in education reform initiatives in Chicago is not clearly defined. Local School Councils (LSC) allow parents to make school related decisions in Chicago. But LSCs are removed from decisions about whether or not to place school on or off probation, and whether or not to close schools based on performance or building utilization. In 2013, African American and Latinx parents expressed outrage over the decision by Chicago Public Schools (CPS) to close 49 schools with protests, including a hunger strike by a group of parents, and pleas to the Chicago Board of Education (BOE). …

Bicycling To Level The Field: A Study Of Divvy In Chicago, Bushra Ghaniwala

Master's Theses

With the onset of COVID-19, norms across the world shifted, including the way people moved in major cities. In order to conduct a comparative analysis, understanding transportation habits before COVID-19 hit cities is important. In this paper, I have focused on Divvy bikes in the city of Chicago, which are touted as a means to achieving first- and last-mile transit especially in underserved communities. I am interested in initiating the line of inquiring into who Divvy bikes served during a time when there was major fear around high transmission of COVID-19 on trains and buses due to the close proximity. …

A Comparative Study Of The Impact Of Regimes In Latin America’S Education Systems: The Cases Of Mercosur, Alba-Tcp, And Pa, Victoria Desimoni

Master's Theses

This thesis presents a comparative study of the regional education policies and programs in three Latin American (LA) regional entities (hereafter ‘regimes’ and ‘regionalisms’): The Southern Common Market (MERCOSUR), the Bolivarian Alliance for the Peoples of Our America – People’s Trade Treaty (ALBA-TCP), and Pacific Alliance (PA). Each of these represents different regionalisms coexisting in LA (hegemonic, post-hegemonic, and counter-hegemonic regionalisms), which makes them ideal for comparative analysis. This project aims to compare these very diverse regimes to interrogate the similarities and dissimilarities, as well as discover who (the regional or the global) is shaping education systems in this area …

Connecting School Climate And Trust: A Content Analysis Of Elements Of Trust In Student And Staff School Climate Surveys, Katherine Thyen

Master's Theses

This study aims to make a concrete connection between trust in schools and school climate. Research indicates that both trust and school climate can positively impact school experiences and performance for teachers and students, but no formal connection has been made between these two elements of schools. In order to answer this study’s research questions of “What differences in frequency and context of trust dimensions exist between student surveys and teacher surveys?” and “How are survey items related to trust dispersed across school climate domains?”, a directed qualitative content analysis was performed. School climate surveys administered to students and teachers …

Constructing Planetary Citizens Through Ecopedagogy In U.S. Social Studies Standards, Madeline Anne Rainey

Master's Theses

The world is in the age of the Anthropocene, where humans are impacting the environment to disastrous effects. The capitalist economy, promoting neoliberal policies of mass consumption, has exacerbated the world's environmental deterioration and social inequity. The rights and responsibilities people hold have been rapidly changing with the fourth industrial revolution. Globalization and Information and Communications Technology (ICT) have further expanded notions of citizenship. While there have been numerous attempts to bring the environment into schools, it has not emphasized what this crisis deserves. Ecopedagogy, as a critical theory, explicitly examines the interplay between environmental and social problems and challenges …

Institutionalism, Peer Culture, And Cultural Reproduction In Active Shooter Drills, Lillian Wynne Platten

Master's Theses

Columbine, Sandy Hook, Parkland: these are words that represent moments in history where schools should have become unprecedented sites of tragedy and isolated events. Except Columbine occurred in 1999, Sandy Hook in 2012, and Parkland in 2016, making them almost commonplace alongside hundreds of other mass shootings in the US. In place of gun regulation, schools are mandated to conduct active shooter drills, which mimic actual shootings through simulated events including the use of rubber bullets and masked actors to produce visceral reactions. Research has shown that these drills have produced trauma and desensitization among teachers, administrators, and counselors; but …

Taking It Too Far? Examining Derogation In Sexism Confrontations, Bayleigh Smith

Master's Theses

Sexism continues to be prevalent within today’s society (Bates, 2012; Crandall et al., 2018; World Health Organization, 2021), creating the need for methods to respond to such bias. Confrontation is one method that allows targets of sexism to stand up for themselves (Haslett & Lipman, 1997; Hyers, 2007; Kaiser & Miller, 2004), but often comes with social costs (e.g., being disliked, Czopp & Monteith, 2003; Dodd et al., 2001; Gulker et al., 2013; Kaiser & Miller, 2001). However, researchers have not dissected the factors that affect the social costs associated with confrontation (i.e., being labeled as a “sexist”, humor, or …

Role Of Tetraspanins In Sars-Cov-2 Fusion And Entry, Marcos Saul Santiago Figueroa

Master's Theses

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the pandemic the world has been facing in recent years. Even as new countermeasures are developed, there is still much we don’t know in terms of its entry into host cells. Tetraspanins are transmembrane proteins that are near ubiquitous amongst cell types. They fulfill numerous roles, including that of a viral co-receptor. Here, we considered whether tetraspanins, specifically CD9, CD63, and CD81 influence SARS-CoV-2 fusion and entry. Using ACE2-LgBit and tetraspanin overexpressing EVs and HeLa cells, we find that the presence of excess tetraspanins inhibit fusion and entry. However, we …

Analysis Of Current And Future Flood Hazard In The Sacramento-San Joaquin Delta, Nicholas L. Mcguire

Master's Theses

The primary motivation of this study is to estimate the current and future flood hazard throughout the Sacramento-San Joaquin Delta in the context of sea-level rise. I also analyzed the effects of storm surge and river flow on extreme events to better understand how these events originate and vary spatially and in time. To address this goal, I combined digital water level records (primarily 1983-present) with archival data collected by the California Department of Water Resources (1929-1983) to reevaluate flood hazard in the Delta and investigate the possible sensitivity of the region different sea-level rise projections. Available archival records from …

Design And Analysis Of A Discrete, Pcb-Level Low-Power, Microwave Cross-Coupled Differential Lc Voltage-Controlled Oscillator, Pavin Singh Virdee

Master's Theses

Radio Frequency (RF) and Microwave devices are typically implemented in Integrated Circuit (IC) form to minimize parasitics, increase precision and tolerances, and minimize size. Although IC fabrication for students and independent engineers is cost-prohibitive, an abundance of low-cost, easily accessible printed circuit board (PCB) and electronic component manufacturers allows affordable PCB fabrication.

While nearly all microwave voltage-controlled oscillator (VCO) designs are IC-based, this study presents a discrete PCB-level cross-coupled, differential LC VCO to demonstrate this more affordable and accessible approach. This thesis presents a 65 mW, discrete component VCO PCB with industry-comparable RF performance. A phase noise of -103.7 dBc/Hz …

A Study Of Pressure Probe Response In Steady And Unsteady Flows, Michael T. Charonnat

Master's Theses

The objective of this thesis is two-fold: to analyze the directional calibration of a 3-hole probe in steady flow and to develop a method for the interpretation of measurements recorded with a novel, fast-response Pitot-type probe in unsteady, turbulent flow. Calibration data for the 3-hole probe’s two side ports was taken in the steady, non-turbulent region of a free jet and was evaluated for symmetry. In addition, data that was recorded using one side port in two independent calibration runs was compared to study repeatability. Misalignment was found between the nominally symmetric data sets, which may be the result of …

Mechanisms Of Substrate Selectivity And Transport By Escherichia Coli Atp- Binding Cassette (Abc) Transporter Metni, Yuchun Chen

Master's Theses

ABC transporters are central in many cellular functions including nutrient uptake, signal transduction membrane assembly, and cellular detoxification. Both structural and functional studies have revealed insights into the high-affinity uptake mechanism of the MetNI methionine ABC transporter. Using the energy from ATP binding and hydrolysis, the MetNI-Q system can import L-Met, D-Met, and other methionine derivatives against concentration gradients. Many mechanistic studies of ABC transporter propose a model in which cognate binding proteins sequester substrates in the periplasm and deliver them to the transporter. In contrast, recent in vivo and crystallographic studies of MetNI-Q suggest that some substrates may be …

Ncaa Di Assistant Coaches' Understanding Of Mental Performance And Mental Health Services, Heather Hill

Master's Theses

The National Collegiate Athletic Association (NCAA) has acknowledged the importance of providing student-athletes with psychological services throughout their athletic careers (NCAA, n.d.). Two vital services for student-athletes are mental performance services that are focused on sport-related issues and mental health services that are centered around personal issues (Sudano & Miles, 2017). Previous literature around mental performance and mental health services has not distinguished between them, making it difficult to understand key stakeholders’ perceptions and knowledge of both mental performance and mental health services. Assistant coaches play an important role in NCAA athletic departments and spend substantial amounts of time connecting …

Smart Spine Tape: Active Wearable Posture Monitoring For Prevention Of Low Back Pain And Injury, Samuel J. Borda

Master's Theses

Back pain and injury are a global health issue and are a leading cause of work and activity absence. Prevention would not only save those affected from the burden of pain and discomfort, but would also save people from loss of over 290 million workdays annually and save the healthcare system billions of dollars in expenses per year. Successful research and development of a wearable technology capable of comprehensively monitoring spinal postures that are leading causes of back pain and injury can result in prevention of mild to severe back pain and injury for high-risk people. To accomplish this, the …

Evaluating Traditional And Novel Modalities Of Self-Monitoring In Females With Low-Literacy & Obesity: A Feasibility Study, Anita H. Kelleher

Master's Theses

This study aimed to determine the feasibility of three distinct self-monitoring modalities employed as part of a weight-loss intervention among Spanish- and Mixtec-speaking women with low-no literacy who were overweight or obese (body mass index, BMI> 25). Primary outcomes assessed include self-monitoring adherence, weight, body composition, and diet quality. Participants (n=18) were recruited from the Cal Poly Women and Infants Mobile Health Unit, and contacted if they had a BMI> 25 and did not attend school beyond elementary level (6th grade). Upon enrollment, participants were asked to attend a weekly meeting at which the lifestyle intervention was delivered by a …

On April 9th, 2022, The Immigrant – Original Score was premiered in front of a live audience in Milne Auditorium on the campus of the University of Northern Colorado with thirteen performers and Jared Lane conducting. This new score was written for Charlie Chaplin’s 1917 film The Immigrant.1 While this score was written to encompass the spirit of Chaplin’s film, it was also intended to introduce this one-hundred-year-old film to modern audiences. The Immigrant – Original Score embodies a synthesis of the music of Chaplin’s day and modern film scoring techniques.

Using Portable X-Ray Fluorescence To Predict Physical And Chemical Properties Of California Soils, Micaela D. Frye

Master's Theses

Soil characterization provides the basic information necessary for understanding the physical, chemical, and biological properties of soils. Knowledge about soils can in turn be used to inform management practices, optimize agricultural operations, and ensure the continuation of ecosystem services provided by soils. However, current analytical standards for identifying each distinct property are costly and time-consuming. The optimization of laboratory grade technology for wide scale use is demonstrated by advances in a proximal soil sensing technique known as portable X-ray fluorescence spectrometry (pXRF). pXRF analyzers use high energy Xrays that interact with a sample to cause characteristic reflorescence that can be …

The Role Of Speech-Language Pathologists In Trauma-Informed Practices: Feelings, Attitudes, And Reported Behaviors Of Colorado School Speech-Language Pathologists, Kallie Haritopoulos

Master's Theses

Research indicates that a majority of children in the United States will be exposed to at least one traumatic event before they turn 18, and some children experience multiple forms. Trauma can cause various adverse effects in physical, cognitive, linguistic, behavioral, social, and emotional functioning, which can affect educational performance and success. Despite the increased chance that children who have experience trauma will receive speech and language services, research surrounding trauma-informed practices predominantly focus on the role of general education teachers and mental health professionals. This qualitative study aimed to understand the feelings, attitudes, and reported behaviors of five Colorado …

Upland Migration Of Coastal Marshes As A Response To Sea Level Rise And Fire Management: Past, Present, And Predicted, Devin Jen

Master's Theses

Coastal marshes are one of the most productive and intensively used ecosystems in the world. However, they are under threat due to natural and anthropogenic stressors, such as sea level rise (SLR). SLR can cause marshes to drown, converting them to open water. Marshes can respond to SLR through landward migration when suitable habitat is available. My research focuses on the landward migration pattern and mechanisms. I evaluated the historical land cover changes at the Grand Bay National Estuarine Research Reserve and the Pascagoula River delta over two-time intervals since 1955 and focused on the forest-marsh dynamics. I found that …

Infidelity And The Bioecological Protective Factors For Mental Health: A Longitudinal Investigation, Lindy Williams

Master's Theses

Infidelity is an important topic of research due to the profound effects on the individual experiencing the trauma. Through the lens of bioecological systems and betrayal trauma, the impact of infidelity on mental health is examined in relation to the most proximal systems to an individual which include personality traits such as agreeableness and neuroticism as well as support from friends, family, and community. This research explores the hypotheses that more support leads to more positive mental health outcomes after the experience of infidelity and the possibility that support from friends, family, and community may buffer specific personality traits and …

Alt-Right Of The_Donald And Authoritarian Communists On Reddit: Internet Memes To Build Community, Joshua Hendricks

Master's Theses

This project infuses Lacanian psychoanalysis further into the rhetorical study by exploring authoritarian discourses on Reddit. I analyze the alt-right community that found a home on the subreddit r/The_Donald and chart their discourse as it shaped from the quarantine to the establishment of an independent forum called TheDonald.win. I selected memes and the comments around them to build the analysis. The second aspect of this thesis examines authoritarian communist discourse on Reddit. The leftist community splintered when r/socialism banned a community member because the person made catgirl art. The ban sent shockwaves through the leftist community on Reddit and generated …

A Bioarchaeological Investigation Of The Courtney-Anderson Cemetery, Lauren Scott

Master's Theses

Located in Perry County, Mississippi, the Anderson Family Cemetery represents an abandoned turn-of-the-century Piney Woods cemetery. The cemetery is located on land once owned by the Courtney and Anderson families, who farmed the area until it was taken under eminent domain by the United States government in 1942. The purpose of this thesis is to present three osteobiographies created from human remains and material culture recovered from three graves excavated from within the cemetery in 2022 to explore the lifeways of rural Piney Woods families of Mississippi at the turn-of-the-century.

Among the graves explored, one did not contain evidence of …

Strawberry Disease Management Improvement For Macrophomina Root Rot And Botrytis Fruit Rot, Yu-Chen Wang

Master's Theses

Strawberry production in California is limited by plant diseases such as Macrophomina root rot (caused by Macrophomina phaseolina) and Botrytis fruit rot (BFR) (caused by Botrytis cinerea). Current disease management strategies are compromised due to fumigant regulations or ineffective disease management practices. This thesis investigated methods to potentially improve the management of these two diseases.

Host plant resistance evaluations for Macrophomina root rot were conducted for the 2020-2021 and 2021-2022 growing seasons. Fifty-one strawberry genotypes were screened in two field experiments where plants were inoculated artificially with Macrophomina phaseolina in both seasons. A wide range of plant resistance …

Relationship Among Department Satisfaction, Training, And Police Behavior, Matthew Garvin

Master's Theses

The call for police reform has been sparked by incidents involving the shooting and killing of individuals by the police. Public and political scrutiny of police behavior and procedures has created a social identity of “Us Versus Them” mentality among police officers. Proactive policing strategies have diminished in response to the heightened scrutiny of police procedures and behavior, in turn, initiating a reduction in police protection and an increase in crime. While research has identified the importance of police presence, the literature does not yet answer questions regarding factors which influence police proactivity. To address the gap in understanding, this …

Pressure Disturbance Upstream Of The Boundary Layer Data System, Michelle S. Leclere

Master's Theses

The primary objective for this work was to evaluate the reliability of computational fluid dynamics (CFD) tools in the prediction of upstream surface pressure disturbance and pressure drag of various instrument excrescence shapes for a small aircraft flight test device called the Boundary Layer Data System (BLDS). Insights on pressure disturbance will serve as a guide for the placement of BLDS probes/sensors, and pressure drag can be used to ensure sufficient adhesive is used to install BLDS instrumentation. The Mach number for all CFD cases was 0.12 and the Reynolds number based on excrescence height varied from 4 x 10 …

The Impact Of Environmental Variability On Perceptions Of Parental Ability From Bodily Cues, Kaitlyn Boykin

Master's Theses

This study aimed to extend work considering how bodily cues appear diagnostic of parental ability. I examined body adiposity and sexually dimorphic features for women (i.e., breast size) and men (i.e., muscularity). I further considered how salience of resource scarcity might heighten perceptions of a potential mate as an effective parent when possessing features that connote underlying resource availability (e.g., body fat). Participants were primed with resource scarcity or a control condition before assessing parental affordances of female and male targets. Targets were orthogonally manipulated to possess high and low levels of adiposity. Female targets were manipulated for breast size …

"Conserving" The Middle Ground: Tennessee's Unionist Press In The Secession Crisis, 1860-1861, Michael Singleton

Master's Theses

This thesis advances scholars’ understanding of how newspaper editors framed and presented news during the secession crisis of 1860-1861. Methodologically, it draws on the publications of seven Unionist editors from Tennessee who initially resisted secession but later pursued different courses during the Civil War. Through this period, editors balanced their roles as journalists and political actors working to advance an ideological cause. Guided by existing practices and their unique journalistic styles, these editors presented a near unified message—influenced by Whig political culture—that framed their response to outside events. This unanimity fractured in 1861 as local pressures, business interests, and personal …

Disturbance Ecology Of The Sonadora River Rock Pool Insect Assemblage At Luquillo Experimental Forest, Puerto Rico, Patrick Gilkey

Master's Theses

Freshwater rock pools can serve as habitat for aquatic insects. Flash-flooding can have profound effects on insect communities in streams and rivers, but these effects have not been studied on freshwater rock pools. The goal of this thesis was to describe ecological patterns of the Sonadora River rock pool insect community at the Luquillo Experiment Forrest, Puerto Rico, specifically in response to intense flash-flooding, and then perform experiments to elucidate possible processes to explain those patterns. The rock pools contained primarily three taxa of Dipteran (true-fly) larvae, in order of decreasing abundance, 1) a newly discovered species of ceratopogonid (biting …

Evaluating The Effects Of Mindfulness Practice On Attentional Control And Episodic Memory, Jacob M. M. Namias

Master's Theses

Mindfulness refers to a mental state of being that involves nonjudgmental acceptance of current cognitions and emotions with awareness of the present moment. Researchers and clinicians have shown the efficacy of mindfulness as a treatment for psychological disorders such as anxiety and depression and have found reductions in reported stress. Building on clinical benefits, mindfulness practice may also facilitate attentional processes as practitioners are required to inhibit distracting thoughts and re-direct their focus to the present moment. My thesis examined the relationship between mindfulness practice and attentional control and potential spillovers to episodic memory. Experiment 1 gauged the relationship between …
