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 …

Speaking Life To A Church In The Process Of Healing And Growth, Emeka Buffong

Master's Theses

Problem

Over the past several years, there has been a marked decline in almost every area of the Niles Philadelphia Seventh-day Adventist Church life. Members have reported feeling overwhelmed with discouragement, and overall commitment has dwindled significantly. This poor morale is reflected by the low numbers at prayer meetings, Sabbath services and other church functions. Furthermore, there is difficulty in filling church offices and even when individuals volunteer to serve in specific offices they often later resign or lose their motivation to serve. Church members often appear to look for excuses to leave. There is a deep sense of discontentment. …

Examining Outcomes And Mechanisms Of The Honest, Open, Proud Intervention In College Students With Mental Illness, Carol Hundert

Master's Theses

Emerging adulthood is a developmental stage involving many changes and transitions (Arnett, 2004). The instability during this time can cause significant distress, making this a period of increased vulnerability for the development of mental illness (Kessler et al., 2007). The rise in the incidence of mental illness on college campuses has caused an increased demand for mental health services (Kadison & Digeronimo, 2004). Unfortunately, college students face many barriers to treatment, including self-stigma (Eisenberg, et al. 2009). Honest, Open, Proud for college students (HOP-C) is a peer-led group-based intervention designed to reduce self- stigma in college students living with mental …

Resiliency, Bajo Que Costó? How Young Undocumented Mexicans Navigate Trauma And Survival, Julia Mendes

Master's Theses

Under the Trump administration, Deferred Action for Childhood Arrivals (DACA) has become a "hot topic" in political discourse and in the media. Amidst this discourse, however, the stories of DACA recipients whose lives are drastically affected by this political drama are often overlooked. Furthermore, a problematic narrative has emerged labeling the "dreamers" as "good immigrants" who need to be saved at the expense of their families, relatives, and other undocumented immigrants who do not fit into the "dreamer" category. Another problematic aspect of current research is celebrating this aspect of "resiliency" that undocumented youth portray and ignoring the consequences this …

What's Wrong With Being Single: Lowered Relational Value Bias Toward Single People, Darian Farrell

Master's Theses

This study examined the perceived relational value of single individuals (compared to that of coupled individuals). I hypothesized that, participants would be more likely to make the conjunction fallacy in the single condition vs. the coupled condition, when asked whether or not it was more likely that the target person from the condition was a single teacher vs. teacher. The data supported my hypothesis: participants in the single condition were significantly more likely to make the conjunction fallacy than participants in the coupled condition. My study also tested whether or not the need to belong acted as a moderator for …

The Potential Effects Of Exercise-Induced Cortisol Release On Executive Functioning In Preadolescents, Kory Matthew Bettencourt

Master's Theses

Purpose: Moderate-intensity aerobic exercise (MAE) has been shown to elicit improvements in cognition and subsequent academic performance among preadolescents. Aerobic exercise has also shown to increase cortisol release in response to increasing exercise intensity. However, it is unknown if increased cortisol levels following exercise are related to acute improvements in executive function following a bout of MAE in preadolescents. The purpose of this study was to examine the potential effects of increased cortisol release after acute MAE on attention and working memory among preadolescents. Methods: Eleven preadolescents [6 males, 5 females] volunteered to participate in this study (age=9.45±1.03). …

Beyond The Reach Of The Safety Net: The Geography Of Social Service Provision In The Context Of Suburban Poverty, Christine Breit

Master's Theses

Poverty rates have risen across the United States since 2000, but the fastest growth in poverty is occurring in the suburbs (Berube and Kneebone 2013). Today, more poor people live in suburbs than cities (Berube and Kneebone 2013). Parallel to this increase in suburban poverty has been federal retrenchment in cash assistance in exchange for service-based assistance (Allard 2004). By and large, the federal government administers social service funds to state governments who then allocate the money to nonprofit entities. This reliance upon local providers creates an uneven patchwork of care (Peck 2008; Allard 2009; Berube and Kneebone 2013) as …

The Loyola Experience: Increasing Belonging And Retention Among Underrepresented Students, Michelle Seli Aku Adzido

Master's Theses

Retaining underrepresented (e.g. first-generation and ethnic minority) students remains a challenge within higher education. Fostering a sense of belonging on campus is key to successfully retaining and increasing academic performance among underrepresented students. Peer-to-peer and faculty mentoring provides opportunities to form social bonds and potentially increase belonging. Mentoring may also connect students from underrepresented backgrounds with campus resources, thus contributing to their knowledge and utilization of campus resources, or self-advocacy. I recruited 95 racial minority and first-generation participants. They reported self-advocacy, belonging, grade point average (GPA), and retention intentions. I test whether participation in a mentoring program (versus control) operated …

A Sociofunctional Approach To Understanding Transphobia, Linas Mitchell

Master's Theses

Despite widespread evidence of anti-transgender prejudice and discrimination, research has yet to determine the nature of prejudice against transgender people. This study used the sociofunctional threat approach (Cottrell & Neuberg, 2005) to examine threat perceptions (contamination threats, obstacle threats, physical safety threats, and threats to reciprocity relations) and emotional reactions (disgust, anger, fear, pity) to transgender (transgender women, transgender men, and nonbinary people) and cisgender (cisgender women, cisgender men, and bisexual people) targets. Results from an online survey suggest that transgender targets evoke higher threat perceptions and negative emotions than cisgender targets; additionally, this tended to be the case for …

Queer People Navigating Experiences With Health Care Providers And Contraception, Dana Lavergne

Master's Theses

Contemporary views of contraception have intrinsically linked birth control to heterosexual sex and pregnancy prevention. As such, contraception is culturally understood to be exclusively for heterosexual women. Despite this, the little work that has been done on queer people1 and contraception use demonstrates they are also accessing birth control (Chrisler, Gorman, Manion, Murgo, Adams-Clark, Newton and McGrath 2015). This schism between the cultural understanding of contraception as a manifestation of heterosexual womanhood and the everyday use of contraception by both queer and heterosexual people takes root in the medical system. Based in heteronormative ideologies, the medical system fails to take …

Immunobiology Of Adenovirus-Vector Vaccines For Mrsa, Emily Orvis

Master's Theses

Staphylococcus aureus is a gram-positive, extracellular bacterium that has emerged as an

important human pathogen. This bacterium is a leading cause of skin and soft tissue infections

(SSTIs) in humans, often leading to invasive and life-threatening infections. Treatment of S.

aureus infections is becoming more complicated due to the rise of methicillin-resistant S. aureus

(MRSA) strains, which are becoming increasingly resistant to a number of antibiotics. In the

United States, invasive MRSA infections result in more deaths annually than any other infectious

agent.

Despite a dire need, there is currently no vaccine against S. aureus infections. The failure

of past …

Union Busted: Understanding The Relationship Between Democrats, Republicans, And Teachers’ Unions, Roman Motley

Master's Theses

There is an almost symbiotic relationship between the Democratic Party and labor unions. Labor unions emerged as the largest donors and staunchest organizers for Democrats. This is all especially true for teachers’ unions. The American Federation of Teachers and the National Education Association represent the largest organizational donors to the Democratic Party. Democrats on the national stage compete fiercely for these two organization’s endorsement. So, if teachers’ unions represent such an important donor and organizing base for Democrats how can we explain Democratic politics on education? Race to the Top was highly unpopular with unions and supported by Democrats. Liberal …

Effects Of Affiliative Motivation And Confrontation Style On Anti-Black Attitudes And Social Consequences, Jamie Patrianakos

Master's Theses

Anti-Black racism occurs on a daily basis and comes with both physical and psychological costs to its targets. One effective way to reduce discrimination is through confrontation, which could come in the form of a hostile accusation of racism (hot confrontation) or a polite emphasis on egalitarian values (cold confrontation). However, confronting often has social costs that may include damaging the relationship between the confronter and the perpetrator. This research determined whether social relationships can reduce anti-Black bias while also serving as a buffer against the social consequences of confronting. Participants (n = 168) were randomly assigned to a 2(affiliative …

A Study Into The Feasibility Of Using Natural Language Processing And Machine Learning For The Identification Of Alcohol Misuse In Trauma Patients, Andrew Phillips

Master's Theses

Alcohol misuse is a leading cause of premature death in the United States, with nearly a third of trauma patients found to have elevated blood alcohol levels upon admission. However, timely intervention has been shown to reduce this. It is thus important to be able to quickly screen patients to identify alcohol misuse. Many medical centers use standardized questionnaires to identify alcohol misuse, but since these instruments are not usually a part of routine care, there are many cases where it is not done.

In this study, large quantities of notes were processed with natural language processing and machine learning …

Toddler Activity Recognition Using Machine Learning, Pinky Sindhu

Master's Theses

Pinky Sindhu

Loyola University Chicago

TODDLER ACTIVITY RECOGNITION USING MACHINE LEARNING

Toddlers behave differently than adults, to say the least. It is valuable to accurately measure the specific types of physical activity (PA) in toddlers; such information can be analyzed to predict future health prospects in relation to conditions like obesity.

We attached ActiGraph accelerometers to the wrist and waist of toddlers and recorded PAs. Toddlers were videotaped, and their movements were annotated as 20 specific activities. These activities were classified into 3 summary activity intensities including sedentary, light intensity PA (LPA), and moderate to vigorous intensity PA (MVPA).

Participation In Medical Research: Reasons Provided In Cognitive Interviews Of A Diverse Sample, Silvia Valadez

Master's Theses

Racial and ethnic minority groups are underrepresented in medical and health-related survey research, with implications for the generalizability across diverse populations of evidence gleaned from these studies. However, there is little known about the respondents’ reasons for participating—or not—in medical research studies, and how these reasons might vary across race/ethnicity, age, gender and education. In this thesis, I extend previous research by looking at data collected from cognitive interviewing techniques to examine 1) participants’ reported likelihood of participating in five increasingly invasive types of data collection, including research studies that ask participants to answer questions about themselves or provide samples …

Surveying Host Innate Immune Responses To Interferon Antagonist-Deficient Murine Coronaviruses, Aaron Brian Volk

Master's Theses

Two coronaviruses (CoVs)—severe acute respiratory syndrome (SARS) virus and Middle East respiratory syndrome (MERS) virus—have emerged in the 21st century from animal reservoirs into the human population, each causing an epidemic associated with significant disease and mortality. CoV epidemics are currently only controllable by rigorous public health measures; no targeted therapeutics or vaccines exist to treat or prevent any human CoV infection. One method of generating attenuated CoV strains to be studied as vaccine candidates involves specifically disrupting CoV-encoded interferon (IFN) antagonists, thereby rendering the virus vulnerable to host innate antiviral immunity. Deubiquitinating (DUB) activity encoded within CoV nonstructural protein …

Characterizing Immune Response To Hiv-1 Infection In Bicd2-Knockout Cells, Omar Abdel-Rahim

Master's Theses

An important part of the HIV-1 infection cycle is the attachment of the intracellular viral core to the host microtubule network, facilitated by attachment of the viral capsid to cargo adaptor proteins. One such cargo adaptor is Bicaudal D Homolog Protein 2 (BICD2). BICD2 can attach to both the HIV-1 capsid and the dynein/dynactin complex and facilitate the trafficking of the viral core towards the host nucleus. Removal of BICD2 can disrupt this viral translocation, resulting in an elevated immune response that impairs productive HIV-1 infection. In my research, we investigated what viral particles are detected in the absence of …

Induction Of Zika Virus-Specific Cd8+ T Cells By Means Of Dna Vaccine, Frank Gambino Jr.

Master's Theses

Zika virus (ZIKV) is a member of the virus family flaviviridae and is transmitted via Aedes aegypti mosquitos. Monoclonal antibodies against dengue virus have been found to cross-react with ZIKV but show no ability to neutralize it. Further studies have shown that Stat2-/- mice given plasma from dengue positive donors exhibit a heightened disease phenotype when challenged with ZIKV. Antibody dependent enhancement is theorized to cause such effect. The goal of this study was to design a plasmid which, when encoded, creates an antigen that will be used to stimulate exclusively CD8+ T cells. The gene sequence of NS3 was …

Cell Intrinsic Characteristics Of Cord Blood Naive Cd4 T Cells, Taylor Keller

Master's Theses

The neonatal immune system is functionally distinct from the adult immune system. Neonatal immune responses are less reactive than their adult counterparts, and as such, have an increased susceptibility to infection, resulting in increased duration and severity of disease. There is evidence that T-cells are partially responsible for the observed immunological differences between neonates and adults. Murine studies on neonatal immunity suggest that Th2 like responses predominate the neonatal immune system, an observation not found in the adult immune system. However, studies on human cord blood revealed that human neonates do not exhibit elevated Th2 like cytokines (with the exception …

An Exploratory Study Of Factors Influencing The Success Of Refugee Youth In College And University, Lea Tienou-Gustafson

Master's Theses

The educational needs, challenges and outcomes of refugee youth in the United States have been studied a great deal, particularly in regard to primary and secondary education. There is a dearth of research, however, on the refugee experience in higher education in the United States.

This study seeks to add to the body of literature on refugee education by exploring shared features of the refugee experience in higher education. Through an in-depth study of refugee youth in Chicago, the study seeks to understand their experiences before, while entering and during college and university, particularly how these experiences are tied to …

This study examines the impact of the current U.S. presidential administration's policies and rhetoric on international student experiences and identities. The researcher approaches this question through the theoretical lens of intersectionality, with the goal of highlighting the complexity and diversity of international student identities in this unique historical moment. Through in-depth narratives collected from interviews with 8 diverse international students, it becomes clear that the 2016 presidential election and the administration's rhetoric and policies have influenced international student experiences and identities in significant ways. Students perceive the statements and actions of the current government to have shifted their perspectives and …

The Characterization Of Rna Content And Biogenesis Pathways Of Extracellular Vesicles That Have Been Implicated In The Pathogenesis Of Hiv-1 Associated Neurocognitive Disorders, Virginia Elizabeth Zwikelmaier

Master's Theses

Patients infected with HIV-1 adhering to Anti-Retroviral Therapy (ART) still suffer from a variety of neurocognitive, behavioral, and motor dysfunctions, collectively referred to has HIV-1 Associated Neurocognitive Disorders (HAND). Current research suggests the manifestations of HAND might in part be due to the dissemination of toxic HIV-1 components throughout the brain via extracellular vesicles (EVs). Our goal is to characterize these pathogenic EVs to begin to gain a better understanding of this EV-mediated pathology.

We took the first steps in developing a technique to assess the microRNA content of individual EVs but it needs to be heavily optimized to eliminate …

A Modular Multi-Level Converter For Energy Management Of Hybrid Energy-Storage Systems In Electric Vehicles, Sharon Sanjeev George

Master's Theses

Electric vehicles (EVs) are substantial applications of clean energy. Their effectiveness for mainstream transportation is predicated on the efficient use of stored energy within the vehicles’ power pack. Among rechargeable storage solutions, lithium-ion (Li-ion) battery cells have high energy density making them suitable to supply the EVs’ average power. However, the peak power requirements of the vehicles exert stress on the Li-ion cells due to their low pulsating power capabilities. Ultracapacitors can be used instead as the power-pulsating storage elements given their superior power density. Incorporating the two cell types for energy storage signifies a hybrid configuration that leads to …

Airborne Doppler Radar Observations Of Pyrocu/Cb Plume Kinematics And Thermodynamics During The 2016 Pioneer Fire, Bruno Rodriguez

Master's Theses

During a period of explosive growth of the Pioneer Fire (Idaho, August 2016), deep pyroconvective plumes were sampled by aircraft. The research aircraft was equipped with both remote sensing and in situ instrumentation, including a W-Band Doppler radar which provided high-resolution vertical velocity retrievals from within the developing pyrocumulus. Being the first direct observations of vertical velocity within a pyrocumulus cloud, they have provided unique insights into the dynamical processes governing pyroconvective environments, with important implications for the fire modeling community. The observations were quality-controlled and corrected for issues such as Doppler velocity aliasing, and the plume’s kinematic structure was …
