Implement “Biographical Disruption” As An Anchor For Critical Reflection In Online Learning, Christopher J. Cachia

Teaching Online Pedagogical Repository

A term first coined by Bury (1982) to describe chronic illness as an embodied break with the experience of everyday life, biographical disruption considers the knowledge that underpins one’s experiences. The following strategy captures how biographical disruption may be implemented as an anchor for (shared) reflection in the online learning environment, including reflection on both content and the online learning process itself. This anchor, coupled with the DEAL framework for critical reflection (Ash & Clayton, 2009), has been utilized as part of an engaging, integral, and powerful opportunity for student discussion and reflection.

Perceived Barriers To And Comfort Levels With Hypothetical Intimate Partner Violence Help-Seeking Among Arab Americans, Jana Mostafa

Electronic Theses and Dissertations, 2020-2023

Members of the Arab American community experiencing intimate partner violence (IPV) face unique barriers to help-seeking and have different comfort levels with using formal and informal resources. This thesis surveyed Arab-Americans to identify perceived barriers and comfort levels with IPV help-seeking. A culturally informed and centered approach was taken to examine connections between individual level factors, perceived barriers and comfort levels in using resources. To do so, I gathered data via an online survey with 82 Arab American participants. Findings suggest that participants perceived the greatest barriers to seeking help for IPV are related to how others view and understand …

Development Of Regolith Simulants Of Lunar Permanently Shadowed Regions And Jupiter Trojan Asteroids, Karlis Slumba

Electronic Theses and Dissertations, 2020-2023

Every scientific experiment or innovation goes through a phase of testing equipment. This is not only true for experiments in the laboratory, but also very relevant for experiments on other planetary bodies. In order to test tools and robotic equipment that are destined for another planet, moon, asteroid or comet, it is necessary to simulate the regolith environment on that surface. In this thesis we have provided an overview of two methods for regolith simulant development. In one approach we made simulants in different compositions to find the best spectral fit to Jupiter Trojan asteroids. At visible to near-infrared (VNIR) …

Using An Interactional Ethnographic Perspective To Explore Insider Perspectives When Working With Previously Archived Records, Michelle Sullivan

Electronic Theses and Dissertations, 2020-2023

Studies in social science fields have examined specific issues in (re)using archived records for qualitative research, though few have focused on the use of private archives in ethnographic research, especially when it comes to foregrounding participant perspectives. In this methodological dissertation I draw on two sets of archived records to demonstrate how an ethnographer can make visible insider knowledge and perspectives when conducting qualitative research with archived records. Utilizing an interactional ethnographic perspective, I construct a dataset for analysis, making my logic visible as I use mapping and transcription, domain and taxonomic analysis, and discourse analysis to foreground insider perspectives …

Who Cares About Virtual Campus Tours? Virtual Tours In The College Choice Model And Perceived Student-Institution Fit, Christopher Thompson

Graduate Thesis and Dissertation 2023-2024

College recruitment practices have remained stagnant for quite some time. However, due to decreases in state funding and hypercompetitive applicant pools colleges must adapt their recruitment practices to remain competitive. Due to precautions and social distancing guidelines which occurred in 2020 caused by the coronavirus pandemic, college information sessions, college fairs, campus tours and other recruitment events were suspended. As such, admissions administrators were forced to rely on virtual recruitment practices, including virtual campus tours, to recruit applicants. Virtual campus tours allow colleges to expand their applicant pool by engaging with prospective students, who may not possess the required finances …

An Equal Wage For All: Investigating The Gender Wage Gap In Opticianry, Christine E. Pinkney

Honors Undergraduate Theses

To better understand the gender wage gap and how it affects licensed working opticians in Florida, an attitudinal survey was constructed using a Likert scale and an online survey instrument through Qualtrics. A pilot study was used with student opticians to investigate the clarity of the questions. This research aimed to learn about Florida opticians' current attitudes toward the gender wage gap in their field and to investigate if this knowledge had somehow affected their decision to stay in the opticianry field. The data from the pilot study indicates that while opticians are aware of the gender wage gap, they …

Authority And Politics: The Relation Between Authority And Political Views Among Those With The Normative Identity Style, Patrick Oefelein

Honors Undergraduate Theses

The purpose of this study was to determine whether a relationship exists between the theorized identity styles and political positions, views, and opinions. Also investigated were the effects of authority on political views, specifically within the normative identity style. Students at a large southeastern metropolitan university (N = 440) took an anonymous online survey in exchange for course credit. Those with a normative identity style, who look to authority figures for answers, were found to have much higher levels of conservatism and held more conservative positions than did those with an informational style, who seek out their own sources for …

Observing The Relationship Between Physical Activity, Overall Health, Anxiety, And Sleep, Brianna Chicas

Honors Undergraduate Theses

College students' mental health has been researched for some time. In particular, the correlation between physical activity and mental health symptoms has been researched. The study examines the relationship between physical activity and anxiety, sleep, and overall health. College undergraduate students at the University of Central Florida took an online survey that measured all of these variables. A Pearson's correlation coefficient was used to assess correlations. Positive correlations were found between anxiety and sleep, anxiety and social desirability, sleep and social desirability, and strength training and vigorous physical activity. Negative correlations were found between overall health and physical activity, overall …

Examining Academic Challenges And Mental Health Among First-Generation And Non-First-Generation Students, Cecilia Q. Bui

Honors Undergraduate Theses

First-generation students are individuals whose parents have not attended college. These students often face challenges such as academic pressures, lack of social support, and mental health problems. Research has found that first-generation students experience a culture shock when transitioning from high school to college. These factors can impact academic success and affect overall health. This quantitative, cross-sectional study examined the impact of stress on mental health among first-generation and non-first-generation students. The study also examined if social and emotional support had a buffering effect on levels of depression, anxiety, and academic stress among first-generation college students. A survey measuring these …

The Joint Effect Of Mindsets And Consequence Awareness On Task Performance, Melinda F. Ammon

Honors Undergraduate Theses

Auditors face strong incentives to execute tasks efficiently and meet deadlines; these conditions are both conducive to – and rewarding of – implemental mindsets. However, an implemental mindset may deprioritize careful analysis and thoughtful decision-making, leading to suboptimal performance and audit quality. Conversely, deliberative mindsets promote critical thinking and open-mindedness – and research suggests auditors in a deliberative mindset perform complex tasks more effectively than auditors in an implemental mindset. Additionally, auditors encounter frequent reminders about the consequences of audit failures. This study examines how these factors (i.e., mindsets and consequence reminders) jointly influence auditors' performance on complex tasks. I …

An Overview Of The Current Alternative Dispute Resolution (Adr) System: Projections For Future Expansion Of Adr Within Florida's Civil Court System, Alysia Rose Patterson

Honors Undergraduate Theses

Currently, mediation in Florida is a pre-suit requirement only for condo associations, homeowner disputes, and medical malpractice suits, as discussed in Florida Statute Chapter 720.311, 718.1255, 766.108, as well as those ordered by a judge. The American Bar Association (ABA) also reported that only 23 of the 204 law schools (11%) approved by the ABA require some form of Alternative Dispute Resolution (ADR) coursework to graduate. Changes need to be made for the ADR program to thrive and reach its full potential within our judicial system. This thesis will highlight that by calling for the government to make mediation a …

Relationship Between Patient Race And Provider Communication, Kristin M. Marino

Honors Undergraduate Theses

Health disparities by race in the United States have been persistent over decades and one possible reason for that could be that physicians are communicating differently with different races. The purpose of this study was to systematically review literature regarding the relationship of patient race/ethnicity with physician-patient communication. The overall project of which this is a part is a mixed methods review, but my part of the study involved only studies using observational data such as audio and video recordings of physician-patient encounters. This study investigated research that compares physician communication with patients across a wide range of ethnic groups, …

Male Pornography Viewers' Perceptions Of Asian Women, Caitlyn M. Koerner

Honors Undergraduate Theses

Objectification and sexual aggression are common themes in pornography. However, there are only a handful of quantitative studies that examine the role of race in pornography that included Asian women, a population that has been fetishized extensively and historically portrayed as hypersexual in mainstream media. There were also no studies on the self-reported attitudes of viewers around this topic. 96 male university students took a survey measuring the frequency and perception of their pornography use, their acceptance of sexual aggression myths, their objectification of Asian women, and their propensity to agree with microaggressions about Asian women. Results indicated that while …

The Effects Of Kangaroo Care On The Stress Levels Of Parents In The Nicu, Niyati Sishodia

Honors Undergraduate Theses

Background: Parents of NICU patients have high stress levels compared to other populations, which negatively impact their mental health. The kangaroo care (KC) method has been used for its numerous benefits for infants, but not as widely studied for its impacts on parental stress. The purpose of this integrative literature review is to examine and synthesize the existing evidence regarding kangaroo care and its impact on the stress levels of NICU parents.

Methods: A literature search was conducted utilizing CINAHL Plus with Full Text, MEDLINE, and APA PsychInfo databases to identify relevant articles. Articles were included if they were published …

The Black American population has the highest prevalence of CKD in the United States, while concurrently possessing prominent genetic risk factors for this chronic disease. The social determinants: healthcare quality and access (extended to account for health behaviors), social and community context, and economic stability were specifically assessed in this review. Key terms were utilized to search electronic databases PubMed and Web of Science, which yielded 470 unduplicated articles. Twenty-nine articles …

Evaluation Of Sleep Benefits Following A 16-Week Judo Program For Children With Autism Spectrum Disorder, Neha R. Chittaluru

Honors Undergraduate Theses

Autism Spectrum Disorder is a neurodevelopmental disorder characterized by language and communication deficits, and difficulties with social interaction (Twisk, 2001). Research has shown that 80% of youth with ASD experience sleep challenges which can lead to sleep-related health issues, exacerbate problematic behaviors, and increase vulnerability to anxiety and depression (Wachob & Lorenzi, 2015; Williams et al., 2004; Richdale & Schreck, 2009). Sleep plays a central role in adaptive functioning, and insufficient sleep can hinder learning, memory, and neuroplasticity for children with ASD (Cohen et al., 2014). As these unhealthy behavior patterns can lead to more adverse long-term health consequences, it …

Comparison Of Health-Related Quality Of Life Trajectories In Older Breast Cancer Patients And Noncancerous Controls Over Ten Years, Maria Eduarda De Azevedo Daruge

Honors Undergraduate Theses

The adverse effects of cancer treatment on health-related quality of life (HRQL) are the primary concern of elderly women diagnosed with breast cancer. The interplay of transient and progressive functional impairments caused by cancer therapies, alongside the accelerated physical declines associated with the normal aging process, are all negatively correlated to HRQL. This study compared the HRQL trajectories between cases and controls for ten years after diagnosis. The cancer group included 1467 women (age ≥ 65), diagnosed with primary breast cancer, registered in the Surveillance Epidemiology and End Results (SEER) cancer registry, and completed the Medicare Health Outcomes Survey (MHOS) …

The Impact Of Telemedicine On Patient-Provider Communication At A University Student Health Center, Venkata Naga Sreelalitapriya Duvuuri

Honors Undergraduate Theses

Effective patient-provider communication (PPC) involves conveying sufficient information to a patient such that the treatment is agreed upon and implemented accurately. Furthermore, a patient must feel adequately involved in the treatment process. With the advent of the COVID-19 pandemic, many clinical visits were shifted online. Although telemedicine was successful in meeting pandemic-specific goals, such as lowering personal contact, it changes the communicative context. Both patients and providers get less input from body language (nonverbal communication) and rely more on verbal communication. Furthermore, the number of telemedicine visits conducted remains elevated over pre-pandemic levels. Much of what is known about effective …

The Effect Of L-Citrulline Supplementation On Blood Pressure: An Updated Systematic Review And Meta-Analysis Of Randomized Controlled Trials, Vraj Amin

Honors Undergraduate Theses

Cardiovascular disease remains one of the most prevalent diseases in the United States and has remained as the leading cause of death. Large Mendelian randomization studies have found significant correlations between high blood pressure and cardiovascular disease (CVD). In fact, high blood pressure is the single most important independent risk factor for CVD. The purpose of this study was to determine the effect of L-citrulline on blood pressure to determine whether it could be advised as an effective treatment for high blood pressure. L-citrulline is a naturally occurring amino acid that readily converts to L-arginine within the human body. L-arginine …

Design And Validation Of A Variable, Speed-Dependent Resistance Training Method For Muscle Hypertrophy, Alvaro Andres Aracena Alvial

Honors Undergraduate Theses

Muscle disorders and induced muscle atrophy impose critical risks to the well-being of an individual, limiting normal activities of daily living. Several resistance training methods have effectively reversed the progression of muscle atrophy. Weightlifting and hydrotherapy are the two widely practiced schemes for resistance training; however, there is the potential risk of excessive loads exerted on the muscles during weightlifting, and limited accessibility and cost are barriers to hydrotherapy. An alternative is using a resistance band. Some limitations include engaging multiple muscles/joints while only unidirectional resistance is feasible. To address these limitations, a VAriable Resistance Suit (VARS) was designed to …

The Relationship Between Task-Induced Stress And Time Perception, Annamarie Brosnihan

Honors Undergraduate Theses

A distortion of time is often reported under the presence of stress or threatening stimuli, for instance motor vehicle accidents or near-death experiences. There is a lack of research on the complexity of time distortion under stress; thus, the present study aimed to explore the relationship between stress and time perception. Given the challenges associated with producing a stress response in a laboratory setting, difficult tasks have been previously used to produce a stress response, such as anagram tasks. However, it remains unknown whether experiencing time pressure while completing a stressful task can also influence time distortion. To investigate this, …
