I Am Relieved To Discover My Symptoms Are Normal For My Condition: An Analysis Of Two Irritable Bowel Syndrome Support Communities, Erin Hvizdak

Master's Theses

Symptoms of Irritable Bowel Syndrome (IBS), a "medically unexplained illness," are present in up to 20% of the United States population. Individuals experiencing symptoms of IBS often report that physicians dismiss their experiential and embodied knowledge, leading to a sense of isolation and frustration. Many of these individuals attempt to diminish isolation and also exchange their knowledge in a community setting. In order to enable a more complete understanding of IBS, a survey about community participation was sent to members of a large online support group for IBS located on Facebook, with 81 completed surveys received. Further, an open-ended questionnaire …

Activity Patterns And Spatial Resource Selection Of The Eastern Garter Snake (Thamnophis Sirtalis Sirtalis), Matthew Gregory Most

Master's Theses

Snake species usually exhibit seasonal variations in activity patterns, home-range size and the use of respective habitat. Using mark-recapture protocols I marked 96 individual Thamnophis sirtalis sirtalis specimens in Lake Forest, IL to determine the independent variables that best explained habitat selection in a population of Eastern Garter Snakes (T. s. sirtalis). Specifically, I focused on the relationship between seasonal movement and home range size of male and female garter snakes. I analyzed the habitat preferences and spatial ecology of Eastern Garter Snakes during the 2011 sampling season and modeled the relationship between preferred or avoided habitat, in conjunction with …

Exosomes: Antiviral Agents In The Human Lung, Jennifer Alexandra Novak

Master's Theses

Hundreds of interferon effectors comprise the immediate host response to virus infection. One family of interferon stimulated genes is the IFITM (Interferon-Induced Transmembrane) proteins. IFITM3, in particular, has been shown to block virus cell entry of Influenza A Virus, SARS Coronavirus, and West Nile Virus, among others. IFITM3 has also been identified as an essential factor for host protection against Influenza A Virus in mice and humans. However, the mechanism by which IFITM3 functions remains unclear.

IFITM3 may function both intracellularly and extracellularly to block virus infection in the human lung. The extracellular milieu contains microscopic vesicles termed exosomes which …

The Interactive Effects Of Coping Strategies, Gender, And Stress In The Prediction Of Internalizing Symptoms In African American Youth: An Application Of The Specificity Model, Cynthia Pierre

Master's Theses

The current study utilized a specificity framework in the examination of interactions among coping strategies, stressor domains, and participant gender in the prediction of depressive and anxiety symptoms. Participants were 273 African American adolescents (6th - 8th; mean age = 12.9; 58% female). Participants completed measures of universal and culturally-relevant coping strategies in response to a stressor. Stressors were coded by raters across dichotomous domains: interpersonality (interpersonal vs. non-interpersonal), duration (acute vs. chronic), controllability (controllable vs. non-controllable), and sexuality (sexual vs. non-sexual). T-tests were conducted to examine differences in reported coping across stress domains. Inconsistent with predictions, mean differences of …

The Relation Of Executive Functions To Active Coping Strategies And Internalizing Symptoms In A Community Sample Of African-American Youth, Arie Zakaryan

Master's Theses

The purpose of this study is to examine the relations between stressor appraisals, active coping, executive functions, and internalizing symptoms in a community sample of low-income African-American youth. There is a dearth of studies assessing how executive functions influence the connection between coping and internalizing symptoms, notably in community and minority populations. When faced with distressing, uncontrollable settings straining the capacity to self-regulate, youth with executive functioning deficits may encounter greater challenges in coping with stressors. Yet, since typically adaptive active coping strategies do not benefit some youth and can result in negative outcomes, it is important to identify what …

Utilizing the engaged methodology of community-based research this project uses the voice of community leaders from both Hammond and Uptown to inform and illustrate what is happening behind the Census data. This includes the role of civic institutions, local government and local business. Through long form structured interviews individuals offered their perspectives, concerns and ideas about how this diversity came about and what challenges and opportunities …

Assessing The Effects Of Titanium Dioxide Nanoparticles On Microbial Communities In Stream Sediment Using Artificial Streams And High Throughput Screening, Alexandra Ozaki

Master's Theses

Nano-titanium dioxide (nano-TiO2) is an engineered nanomaterial used in a wide array of commercial products. The production and use of large amounts of nano-TiO2 is resulting in the unintended release to the environment. Nano-TiO2 is known to be cytotoxic due primarily to its ability to generate reactive oxygen species, and negative impacts on a variety of organisms have been demonstrated, but the effects of nano-TiO2 on complex microbial communities under ecologically relevant conditions have rarely been tested. We conducted a controlled manipulative experiment using recirculating model streams dosed with a one-time amendment of 1mg L-1 nano-TiO2 (specifically P25). Within one …

Antibodies To Inhibit Clostridium Difficile Adhesion To Human Gut Epithelial Cell Line, Wonbeom Paik

Master's Theses

Clostridium difficile infection (CDI) is a major hospital-acquired diarrhea that can cause life-threatening complications such as pseudomembranous colitis. CDI is caused by colonization of host with C. difficile, a Gram positive, anaerobic bacterium known to produce toxins that cause disease. Normally, the gut microbiota protects the host from CDI, but disruption of the microbial composition through antibiotic treatment can leave one vulnerable for CDI. To date, no vaccines for preventing CDI are available.

In this study, the potential of antibodies directed against specific surface molecules of C. difficile to block bacterial adherence to host gut epithelial cells was studied, in …

Effectiveness Of Peer Mentoring In First-Year Program Classrooms, Katherine Casey

Master's Theses

First-year programs (FYPs) for college students offer extended orientation to campus resources and provide first-time freshmen with essential skills for academic success, and many believe that the effectiveness of FYPs increases with the presence of peer mentors. The present study measured the added effectiveness of peer mentoring in FYP classrooms with knowledge of campus resources as a dependent measure. Ninety one first-year students in nine sections of FYP classes participated in this quasi-experimental study. Seven of the classes had peer mentors (n = 70), and the two control classes (n = 21) did not have peer mentors in the classroom. …

An Ecological Assessment Of Insect Diversity At Organic Central Coast Vegetable Farms On Two Spatial Scales, Emily Musgrave

Master's Theses

Modern industrial agriculture is the principal cause of anthropogenic land use changes for terrestrial ecosystems. Approximately 40% of the planet's land surface, or half of the habitable area, is now composed of agricultural landscapes. The simplification and industrialization of agriculture are the biggest drivers of global biodiversity loss, especially on Californian's Central Coast. Diversified organic agriculture, however, may offer some refuge for non-crop species. In this study we analyzed insect and plant biodiversity on and adjacent to organic vegetable farms on the Central Coast of California at two spatial scales, the landscape-scale and a smaller within-farm scale. At the landscape-scale, …

This Could Be A Game!": Defining Gamification For The Classroom, Darcy Elaine Osheim

Master's Theses

Instructors find a gap between what they experienced in school in the mid-to-late 20th century and the experiences of students entering college in 2012/13. In the United States, the influx of almost universal access to technology has marked this generation in a way the previous generations must work to understand, and gamification is a strategy used in areas like marketing to gain participation from this age group. Gamification is a strategy that employs game mechanics, techniques, and theory in areas that traditionally are not set up to function like a game. The purpose of this study was to define gamification …

Experiences Of Coping With Injury In Division I Athletes From Low-To-Middle Socioeconomic Status Backgrounds, Matthew Philip Bejar

Master's Theses

Injuries inevitably occur in any sport at any level. The integrated sport injury model is one of the most extensive frameworks to address the psychological responses to athletic injury. While this model posits that socioeconomic status (SES) influences how an athlete cognitively, emotionally, and behaviorally responds to an injury, no research has substantiated this claim. Low SES individuals experience an exceptional amount of stress, which may complicate how they cope with a negative event. The coping strategies employed by an athlete can have major implications on rehabilitation adherence, recovery time, and psychosocial well-being. The purpose of this study was to …

An Examination Of American Sport For Development And Peace Interns' Program Experiences, Michael Sanh Dao

Master's Theses

Sport for Development and Peace (SDP) is an international development movement that uses sport to address international humanitarian issues, including education on preventing HIV/AIDS, peaceful resolutions in communities experiencing conflict, and establishing gender equality in male-dominated societies. The emergence of SDP as a branch of international development over the last decade has garnered much attention. National governments, non-governmental organizations, and scholars have involved themselves in the process of SDP. The attention that SDP has attracted by these parties has been both practical and theoretical. Scholarly studies by prior researchers on SDP have included suggestions on best practices, and how people …

Women In Science, Technology, Engineering, And Mathematics (Stem) Fields: The Importance Of The Need To Belong And Self-Esteem On The Intention To Leave A Job, Jung Eun Lee

Master's Theses

The purpose of the study was to predict individual intentions to leave science, technology, engineering, and mathematics (STEM) field jobs. Psychological predictors were gender, the need to belong, self-esteem, perceived personal discrimination, and perceived group discrimination. We used the Amazon Mechanical Turk to recruit participants and Survey Monkey to conduct an online survey. Participants were 174 men and women who worked or studied in STEM fields. Two-step hierarchical linear regression analyses were performed to analyze the data. As a result, we found that all predictors mentioned above accounted for the variance in the intention to leave a job. Self-esteem and …

The Effects Of Indoor Climbing Route Rating Manipulation On Participant Climbing Self-Efficacy, Phillip James Sandlin

Master's Theses

This quantitative study utilized a classical experiment design to explore the

effects of manipulation of indoor climbing route ratings on the climbing self-efficacy of 90 indoor rock climbers. Controversy surrounding the accuracy of the assigned ratings of indoor climbing routes is commonplace at indoor climbing facilities. For indoor rock climbers to accurately assess their abilities, set appropriate goals, and monitor their progress, they must be able to choose climbs that accurately represent their desired level of challenge. Statistical analysis of the data did not support a relationship between manipulation of climbing route ratings and any changes in participant climbing self-efficacy. …

Funding Sources Of Impactful And Transformative Research, Barrett Anderson

Master's Theses

Understanding how the most important scientific articles have been funded can help inform and improve future funding decisions. Importance is here defined as science that, in the metaphor of the tree of knowledge, plays a structurally significant role (e.g., creates new branches of knowledge or transforms existing ones). The structural significance of articles is broken down into two submeasures: citation count and "generativity" (a novel measure defined as being highly cited and also leading to a comparatively large number of other highly cited articles). Generativity is an attempt to provide a quantitative operationalization that should correlate with transformativeness, a concept …

Future Work Selves And Work-Related Outcomes: The Role Of Perceived Supervisor Support, Shama Arakeri

Master's Theses

The purpose of this study was to examine the relationships between future work selves and work-related outcomes such as proactive career behaviors, self-development organizational citizenship behaviors (OCBs), and work engagement. Future work self salience was used to capture employee work selves that could be easily and clearly recalled into memory. An additional purpose of the current study was to examine whether perceived supervisor support would moderate each of the three relationships. A total of 123 employees participated. Future work self salience was positively related to proactive career behaviors, self-development OCBs, and work engagement. Furthermore, perceived supervisor support was found to …

Farms On Campus: Strong Stakeholder Support For An Educational Garden At A Non-Land-Grant University, Gina M. Bacigalupi

Master's Theses

University farms and gardens are increasingly seen as effective tools for learning a variety of academic subjects and as resources that allow users to connect experientially to nature. Most existing university farms, however, are found at resource-rich land-grant universities. This research evaluated stakeholder interest and willingness-to-pay in money, time, and labor for a proposed educational farm at a public, urban, non-land-grant university through an online survey of over 400 members of the California State University East Bay, Concord Campus community. Overall, support for an educational farm at this site was high amongst all stakeholder groups. Students and stakeholders who hold …

The Effect Of Dietary Methylmercury On Na+, K+, -Atpase Activity And Growth In Fall-Run Chinook Salmon (O. Tshawytscha), John Negrey

Master's Theses

Hatchery reared Chinook salmon from California's Central Valley were fed for 67 days (Apr-Jun, 2008) on fish pellets mixed with either 0, 1, 3, or 5 µg*g-1 methylmercury hydroxide. Weight, fork length, condition factor, and Na+,K+- ATPase measurements were determined every two weeks and a 96-h seawater challenge was conducted at the conclusion of the experiment.

A total of 50 interviewees participated in the study. Results indicated that job applicants did manipulate their Facebook pages for employment purposes for various reasons with the most common reason being to avoid misperceptions by potential employers. Another goal of this study was to examine job applicant beliefs on employer and job applicant use of Facebook for employment purposes. The study results indicated that job applicants supported …

Game Theory Approach To Transportation Network Vulnerability Measurement, Qixing Wang

Master's Theses

The vulnerability of a transportation network is strongly correlated with the ability of the network to withstand shocks and disruptions. A robust network with strategic redundancy allows for the redistribution or reassignment of traffic without unduly compromising system performance. As such, high-volume edges with limited alternative paths represent system vulnerabilities – a feature of transportation networks that has been exploited in the past to identify critical components. In this thesis, a mixed-strategy, two opponents, non-zero sum, combinatorial game theoretical framework are presented for measuring network vulnerability. Two solution approaches (Shortest Path Algorithm with Entropy function (SPE) & User Equilibrium Assignment …

Weather-Based Damage Prediction Models For Electric Distribution Networks, David W. Wanik

Master's Theses

From thunderstorms to hurricanes, electric distribution networks are subject to a wide range of warm weather storm events. Tropical Storm Irene (2011) and Hurricane Sandy (2012) are two events in recent memory that disrupted over half of The Connecticut Light and Power Company’s (CL&P) service territory, which left some customers without power for up to eleven days. This research study investigates a damage prediction framework for both thunderstorms and hurricanes that combines two generalized linear models to probabilistically determine the occurrence and extent of damages, known as trouble spots, to the overhead power distribution network. The models are inputted with …

The Odious Debt System, Andrew Hanauer

Master's Theses

Over the past forty years, African countries have accumulated enormous quantities of external debt. Today, this debt is heavily burdensome; money spent on debt service is money that cannot be invested into infrastructure development, health, education, or other areas that might benefit the large number of Africans who live in poverty. Calls for debt forgiveness have led western institutions to forgive a portion of this debt, but have not addressed the question of whether or not this debt is legitimate in the first place.

Similarly, academic proposals for the classification and subsequent repudiation or forgiveness of so-called "odious debt" have …

A Practical Scale For Multi-Faceted Organizational Health Climate Assessment, Zandra M. Zweber

Master's Theses

The current study sought to develop a practical scale to measure workplace health climate in a way that has not previously been conceptualized – as a three-faceted approach from the employee perspective serving as an indicator of a healthy organization. The goal was to create a short, useable yet comprehensive scale that could translate into practical use by organizations and occupational health professionals planning workplace interventions. To accomplish this, the proposed multi-faceted organizational health climate scale (MOHCA) assesses three-facets which match up with three organizational levels: 1) organization 2) supervisor and 3) workgroup. Ten items were developed and tested on …

Utilizing a qualitative research approach, four focus groups with 25 Somali women, two focus groups with 12 Somali men, one focus group with Somali religious leaders and seven in-depth interviews with American healthcare professionals were conducted in Minneapolis to help develop culturally sensitive reproductive health programs for Somali mothers. Twenty key distinctions between Somali cultural traditions and Western medicine were identified. For many Somali women, prenatal care is a new concept. There …

The Lavender Tide: Lgbtq Activism In Neoliberal Argentina, Andrew Shaffer

Master's Theses

Beginning with the legalization of same-sex marriage in 2010 and following up with the passage of the gender identity law of 2012, Argentina has quickly catapulted itself to the forefront of LGBTQ (lesbian, gay, bisexual, trans*, queer) rights in the world. This study sets out to answer a simple question: how did these vast legal changes come about in a country whose LGBTQ citizens are still met with hostility and discrimination? In order to answer this question I look at the ways LGBTQ activists have argued for the civil rights that they have achieved, and measure their success by analyzing …

This thesis reviews the literature on women’s mobilization in Latin America during the second half of the twentieth century. I find that women mobilized across class lines with the masses to end dictatorships. Women demobilized during transitions to …

The Globalization Of Cosmetic Surgery: Examining Bric And Beyond, Lauren E. Riggs

Master's Theses

What is driving the globalization of cosmetic surgery? Using BRIC (Brazil, Russia, India, China) countries as a model, this master's thesis systematically identifies and analyzes (1) the origins of cosmetic surgery in historical, regional, and country-specific terms, and (2) examples of how cosmetic surgery has become normalized. As a result, clear patterns emerge in regards to: embedded power structures related to racism and war; the results of Western interests rapidly opening countries’ markets to high media and corporate influence—especially in the wake of political oppression and austerity; the exacerbation of pre-existing class, color, race, and gender prejudice by hyper-consumerism; the …

A Tale Of Two Superpowers: Nigeria And China Relations, Faouziatou Aboudou Kabassi

Master's Theses

The study discusses the historical development of the Sino-Nigerian bilateral relations. The paper provides a detailed view of china's FDI in Nigeria and the diverse challenges faced by the oil rich country to develop its own economy through NEEDS as a result of china's economic power. China’s partnership with Nigeria is ideally for economic growth but practically poisonous to Nigeria’s development goals as China is solely pursuing its own interest and diverting its partner from working toward its NEEDS goal. A deep investigation of the relations should be reviewed for both countries. This will be needed to produce vital economic …
