Comparative Proteomics: Assessing The Variation In Molecular Physiology Within The Adductor Muscle Between Mytilus Galloprovincialis And Mytilus Trossulus In Response To Acute Heat Stress, Joshua Scott Mier

Master's Theses

Increases in seawater temperatures have imposed physiological constraints which are partially thought to contribute to recently observed shifts in biogeographic distribution among closely related intertidal ectotherms. For instance, Mytilus galloprovincialis an introduced warm-adapted species from the Mediterranean, has displaced the native cold-adapted congener, M. trossulus, over large latitudinal expanses off the California coast. Several comparative physiological studies have revealed interspecific differences in thermal tolerance, including variation in aerobic metabolism and gape behavior, which suggest the invasive congener is better adapted to acclimate to increasing seawater conditions as predicted due to climate change. However, current analyses seek to discover the …

But I Need My Money Now: A Stratified Propensity Score Analysis Of The Effects Of Retirement Decisions Made During The Great Recession On Income Mobility, Zachary Kline

Master's Theses

The Great Recession and accompanying financial crisis that occurred between 2007 and 2009 presented a host of emergency expenses to Americans with historically low traditional savings while at the same time limiting their access to credit. The resulting increase in poverty and decrease in real median family income raises the question: What if more Americans had access to liquid, emergency funds? The United States’ retirement system increasingly relies on choice-based public policy programs that allow individuals to access their retirement funds by “cashing out” during financial hardship. Proponents of choice programs may expect individuals who cash out of their retirement …

Nanoscale Mapping Of In-Situ Micro Electro Mechanical Systems With Atomic Force Microscopy, Manuel Rivas

Master's Theses

Micro-electro-mechanical-systems (MEMS) are increasingly at our fingertips. To understand and thereby improve their performance, especially given their ever-decreasing sizes, it is crucial to measure their functionality in-situ. Atomic Force Microscopy (AFM) is well suited for such studies, allowing nanoscale lateral and vertical resolution of static displacements, as well as mapping of the dynamic response of these physically actuating microsystems. In this work, the vibration of a tuning fork based viscosity sensor is mapped and compared to model experiments in air, liquid, and a curing collagen gel. The switching response of a MEMS switch with nanosecond time-scale activation is also monitored …

An Overview Of Body Armor And Single Plate Impact Dynamics, Thomas Matzinger

Master's Theses

In the past, personal body armor was constructed of simple plates of high- strength alloys. However, with the advancement of modern combat and weaponry, particularly armor-piercing ammunition, personal body armor has evolved into more complex and effective metal, ceramic, and composite structures. This paper lays the groundwork for experimental and modeling methods used to understand the effectiveness of new armor designs. Focusing on the first layer of modern body armor, the ”High Impedance” layer. Experiments measuring the change in velocity of bullets passing through aluminum and titanium plates were conducted. These experiments were then replicated through FEA simulation.

Assessment Of Maternal And Infant Outcomes Of Moderately Malnourished Pregnant Adolescents In Malawi, Alyssa Marie Friebert

Master's Theses

Background: Adolescent childbearing and maternal malnutrition are common in low- and middle-income countries and are associated with increased risk for poor maternal and infant outcomes. Adolescent pregnancy compounded with moderate malnutrition exacerbates outcomes common to both individually. Supplementary foods may be a way to improve outcomes in malnourished adolescent pregnant women.

Objective: To retrospectively assess maternal and infant outcomes in moderately malnourished pregnant young adolescents (16-17 YO), older adolescents (18-19 YO), and adults (≥20 YO) in response to one of three nutritional interventions and in a pooled treatment group analysis, and to assess differences in infant outcomes by infant gender. …

Predicting The Nitrogen Fertilizer Response Of Turfgrass Based On Solvita® Soil Test Results, David Moore

Master's Theses

Nitrogen (N) fertilizer recommendations are very difficult to make for turfgrass because N is transient in the soil and because the N mineralization potential of soil can be difficult to predict. This study was conducted to determine the relationship between turfgrass performance and Solvita^® Labile Amino N (SLAN) and Soil CO₂-Burst (SSCB) tests. Kentucky bluegrass (Poa pratensis) and tall fescue (Festuca arundinacea) turf plots received 23 rates of organic fertilizer and 4 rates of urea, and were evaluated separately for five measures of turfgrass performance: total foliar N, normalized difference vegetation index, chlorophyll …

Development Of Zonal Safety Performance Functions For Local Road Intersections And Segments In Connecticut, Ishraq Rayeed Ahmed

Master's Theses

Crash counts at a location are predicted using a Safety Performance Function (SPF) equation. The expected number of crashes on a traffic facility can be estimated using SPFs and the required countermeasures can be taken to reduce crashes in future. Due to the absence of sufficient traffic count data for local roads, new crash prediction approaches are essential to implementing highway safety improvement strategies. The study focuses on developing SPFs with coefficients varying by geographic covariate for segment and intersection crashes on local roads in Connecticut. Demographic and network topology data has been used as a surrogate for traffic count …

Development Of A Novel And Dynamic Shear Rheometer Based Extensional Deformation Test To Replace Force Ductility Test, Waleed M. Omer

Master's Theses

Modification of asphalt binders is essential to improve the physical and rheological properties of asphalt and to reduce the aging effect. The use of polymers to modify asphalt is the most common approach in asphalt modification. Force ductility test has been a challenging topic as an indicator of asphalt performance, especially for the modified asphalt binders. The significance of the force ductility test as a measure of fatigue and thermal cracking has been debated because of its low reproducibility, empirical nature and the unclear relationship with the fundamental asphalt properties, especially with modified asphalt binders [1]. Extensional deformations tests where …

There are two main automation goals of this thesis that are reflected in the core of the …

The Politics Behind The National School Lunch Program, Jaylyn Brown

Master's Theses

The National School Lunch Program (NSLP) is one of the longest federally funded programs in the United States. The program is meant to provide food that is nutritious and affordable to schoolchildren. Indeed, most students receive free or a reduced price lunch highlighting the importance of affordability and nutrition in the school lunch system. Since the creation of the NSLP in 1946 debates about food quality and nutrition standards have consumed school lunch reform discussions. Many health organizations stress the importance of child nutrition, and advocate for the means to prevent diseases such as childhood obesity, diabetes, and heart disease. …

Characterizing The Roles Of Staphylococcus Aureus Secreted Factors In Virulence And Modulation Of Innate Immune Cell Activity, Cameron Harvey

Master's Theses

Staphylococcus aureus is a prominent human pathogen that is responsible for a massive burden on healthcare. This thesis takes two approaches to characterize how S. aureus secreted factors subvert the innate immune response. First, characterization of the integral membrane protease 1984 showed that it regulates secretion of a putative lytic transglycosylase, IsaA, which is implicated in virulence. My results suggest IsaA and 1984 are capable of modulating immune responses that result in enhanced heart colonization in vivo. In addition, recent studies have uncovered TLR-independent pathways that induce inflammatory responses after S. aureus insult. Therefore, I hypothesized the bacterium secretes factors …

Chronic Circadian Misalignment Leads To Reduced Longevity And Largescale Changes In Gene Expression In Drosophila Melanogaster, Alex Christ Boomgarden

Master's Theses

As a result of earth's orientation toward the sun producing day and night, organisms have evolved an endogenous circadian timing system that is responsible for the 24-hour oscillation of most physiological and behavioral processes. This timing system is constantly synchronized to the external environment to adapt to and anticipate changes in light, temperature, food, and mate availability. In modern society, social and work constraints cause people to live schedules that are out of sync with their internal circadian clocks, producing a chronic circadian misalignment (CCM). While epidemiological studies in humans point to potentially damaging metabolic and cognitive consequences of CCM, …

Machine Learning Methods For Kidney Disease Screening, Rathna Ramesh

Master's Theses

The number of people diagnosed with advanced stages of kidney disease has been rising every year. Early detection and constant monitoring are the only way to prevent severe kidney damage or kidney failure. Current test procedures require expensive consumables or several visits to the doctor, which results in many people foregoing regular testing. To address this problem, we propose a cost-effective teststrip-based testing system that can facilitate kidney health checks from the comfort of one’s home by using mobile phones. The specially designed teststrip facilitates a colorimetric reaction between alkaline picric acid and creatinine in a blood sample that has …

Paul explicitly addresses the issue of circumcision for the first time in the epistle of Galatians in chapter 5:2–6. The precise meaning of circumcision, however, both historically and exegetically, has been much debated in Pauline scholarship.

Method

This thesis will first provide an overview of how circumcision has been interpreted in the context of different approaches to Pauline theology. Then, the historical background of the significance of circumcision around the first century AD will be analyzed, both in the Jewish and the Greco-Roman context. Finally, an exegetical study of Galatians 5:2–6 will focus on how Paul addresses the topic …

Pain And Academic Performance In Youth With Spina Bifida: The Mediating Role Of Neuropsychological Functioning, Diana Margaret Ohanian

Master's Theses

Objective: The current literature has identified few modifiable condition parameters associated with academic performance in youth with spina bifida (SB). Nevertheless, youth with SB are more likely to struggle academically than their typically developing (TD) peers. Therefore, identifying areas for clinical intervention is paramount. Pain, an understudied secondary condition in youth with SB, has been found to be associated with poorer academic performance in TD youth. Further, neuropsychological functioning has been found to be both negatively associated with pain and positively associated with academic outcomes. The aims of this study were to examine (1) the relationship between pain and academic …

Consistency Of Health Behaviors And Relations To Bmi In First Year College Students, Laura Nicholson

Master's Theses

Existing research suggests that individuals with erratic schedules (e.g., shift workers) may be at greater risk for weight gain. This may be due, in part, to the inconsistent timing of health behaviors, such as sleep. Little is known, however about the relevance of the consistent timing of health behaviors among other populations, including college students who are risk for weight gain. The current study examined the consistency of three health behaviors (i.e. sleep, eating occurrences, and physical activity) and relations with body weight among first year college students at a large Midwestern university. Daily diary methods were used to collect …

Police Beats And City Streets: An Examination Of Black American And Latinx Youth Interactions With And Perceptions Of Police, Ogechi Onyeka

Master's Theses

Existing research on issues of race and police suggest that Black Americans and Latinx youth tend to have more negative experiences with, and views of, police than individuals from other ethnoracial groups. This finding is even more robust among Black American and Latinx youth, notably those living in low-income and high crime communities. The victimization and constant burden such perceptions of police and police interactions have on Black American youth can potentially cause psychological damage. When coupled with repeated exposure to social, economic, and racially-related stressors, the former may result in greater adverse psychological outcomes. However, resilience factors such as …

Reflections On Life: Replication And Extension, Karen Osowski

Master's Theses

This study used an experimental methodology to examine positive affect and gratitude as mediators of the beneficial impact of an intervention in which older adults savor "life lessons" they have learned in growing older on measures of psychological well-being (i.e., positive attitudes toward aging, life satisfaction, anxiety, state self-esteem, and state hope). In the following pages, I first review the background literature on gerontology and quality of life as well as describe, in detail, the original experiment (Smith & Bryant, 2018) that formed the foundation of the proposed research. Next, I describe several extensions of this earlier study that are …

It's About Time: Length Of Incarceration, Gang Membership, And Recidivism Among Illinois Prison Releasees, Henry Douglas Otto

Master's Theses

This study explored the effect of time spent incarcerated on recidivism among a sample of individuals released from IDOC facilities from 2011 to 2014 (N = 72,716). Gang members were compared to non-gang members in order to evaluate the potentially heterogeneous nature of the effect of length of stay on recidivism within the competing frameworks of deterrence theory and social learning theory. The samples were further split into separate analyses based on the current felony class, and length of stay was operationalized as incarceration in months and split into quartiles based on the distribution of each felony class sample. The …

The research question for this project is; In what ways do Black youth use Black television as a tool in school social settings? This study took a qualitative approach that called for the method of focus groups. Black students between the ages of 10-20 gathered into four focus groups to discuss how they use Black content to communicate with their peers. The results of the research show that Black youth use Black television as a …

Voices From The Margins: Service Providers Perspectives On Empowering Refugee Women, Deidra Ann Coleman

Master's Theses

Refugee women face considerable challenges while fleeing their countries, and attempting to adjust to their new lives in their host country. As a result of being both a woman, and a member of a marginalized group, refugee women tend to suffer disproportionately during displacement and and resettlement (UNHCR, 2015). They are more likely to be discriminated due their gender and ethnicity, and to lack the necessary community supports and resources needed to overcome barriers they encounter. In response to the refugee crisis, service organizations have emphasized empowerment as a key way to improve the lives of refugee women. While there …

Examining Recidivism And Correlates Of Yasi Scores Among Youth Released From Idjj, Claire Fischer

Master's Theses

There are two main purposes of this research: 1) to provide the Illinois Department of Juvenile Justice (IDJJ) with an updated picture of recidivism and 2) to determine how YASI risk/needs/protective domains and risk scores relate to post-release recidivism. To date, the research that is available regarding youth recidivism is fraught with methodological concerns (i.e., inconsistency in measurement). Moreover, there have been no systematic analyses of the YASI in Illinois since its implementation within the IDJJ. Thus, the present research will attempt to fill in the gaps by assessing rates of juvenile recidivism, the degree to which needs identified by …

The Neurobiological Correlates Of Savoring, Ian James Kahrilas

Master's Theses

Personality traits pertaining to positive emotion may be a key factor in deriving vitality from our lives. Positive affectivity refers to one's disposition to experience intense and frequent episodes of positive affect, while savoring capacity refer to one's ability to regulate positive affect. Both traits have been positively associated with happiness, self-esteem, prosocial behaviors, improved health outcomes, as well as attenuated depressive symptomatology and neuroticism. The late positive potential (LPP) is an electroencephalography (EEG) component that is theorized to index a visual cortical/amygdala pathway that is involved in evaluating the affective salience of stimuli. LPP is sensitive to the emotional …

Analysis Of Fiber Network Architecture In Blood Vessels And Blood Clots, Dustin Michael Nguyen

Master's Theses

Fibrous networks, including collagen and fibrin, provide strength and support, and are critical for maintaining homeostasis. In this study, we have developed algorithms to define the structural properties of collagen and fibrin networks from microscopic images of these networks in abdominal aortic aneurysms (AAA) and blood clots, respectively. AAA is a biomechanical disease characterized by significant changes in the structure and strength of the arterial wall due to differential changes in the composition of fibrillar collagen in adventitial and medial layers. Using bright-field and polarized microscopic images of histological sections of mouse aorta stained with Picrosirius red (PSR) stain, we …

The Conservation, Excavation, And Analysis Of Ancient Human Remains: A Bioarchaeological Case Study Of Prehistoric Reburials From Nevis, West Indies, Marissa Nicole Massaro

Master's Theses

In the summer of 2015, the cranium of what seemed to be an indigenous Caribbean individual was discovered partially exposed on White’s Bay Beach, Nevis. The following year, upon excavation of two known burial sites, a test pit brought forth an additional burial of two individuals dating about 1025-1275 AD. Currently, there is very little known about this period causing confusion about the migration and settlement patterns of the Caribbean people during this time. Additionally, the Nevis Historical and Conservation Society is experiencing rising concerns of the demolition and utilization of their historical land and beaches for infrastructural development. As …
