Holding Off On The Fun Stuff: Academic Media Multitasking And Binge Watching Among College Students, Kelly Merrill Jr.

Electronic Theses and Dissertations

College students are often faced with the temptation of engaging in academic media multitasking and binge watching or completing their academic coursework in a timely and effective manner. A quantitative survey (N = 651) explored trait individual differences in self-control and academic delay of gratification and situational individual differences in enjoyment, reward, procrastination, regret, and guilt as predictors of academic media multitasking frequency, binge watching frequency, and binge watching duration. Stepwise regressions reveal that self-control is not a predictor of these media behaviors, while age and greater enjoyment were the only predictors of academic media multitasking and gender and greater …

Mechanism Design Of A Compact 4-Dof Robotic Needle Guide For Mri-Guided Prostate Intervention, Shihao Zhang

Electronic Theses and Dissertations

In the past several MRI compatible robotic needle guide devices for targeted prostate biopsy have been developed. The large and complex structure have been identified as the major limitations of those devices. Such limitations, in addition to complex steps for device to image registration have prevented widespread implementation of MRI-guided prostate biopsy despite the advantages of MRI compared to TRUS. We have designed a compact MRI-guided robotic intervention with the capability to have angulated insertion to avoid damage to any anatomical feature along the needle path. The system consists of a novel mechanism driven Robotic Needle Guide (RNG). The RNG …

Role Of Single Nucleotide Polymorphisms (Snps) In Ptpn2/22 And Mycobacterium Avium Subspecies Paratuberculosis (Map) In Rheumatoid Arthritis And Crohn's Disease, Robert Sharp

Electronic Theses and Dissertations

Both genetic pre-disposition and potential environmental triggers are shared between Rheumatoid arthritis (RA) and Crohn's disease (CD). We hypothesized that single nucleotide polymorphisms (SNPs) in the negative T-cell regulators Protein Tyrosine Phosphatase Nonreceptor type 2 and 22 (PTPN2/22) lead to a dysregulated immune response as seen in RA and CD. To test the hypothesis, peripheral leukocytes samples from 204 consented subjects were TaqMan genotyped for 9 SNPs in PTPN2/22. The SNPs effect on PTPN2/22 and IFN-y expression was determined using RT-PCR. Blood samples were analyzed for the Mycobacterium avium subspecies paratuberculosis (MAP) IS900 gene by nPCR. T-cell proliferation and response …

Semiconductor Design And Manufacturing Interplay To Achieve Higher Yields At Reduced Costs Using Smart Techniques, Ankush Bharati Oberai

Electronic Theses and Dissertations

Since the outset of IC Semiconductor market there has been a gap between its design and manufacturing communities. This gap continued to grow as the device geometries started to shrink and the manufacturing processes and tools got more complex. This gap lowered the manufacturing yield, leading to higher cost of ICs and delay in their time to market. It also impacted performance of the ICs, impacting the overall functionality of the systems they were integrated in. However, in the recent years there have been major efforts to bridge the gap between design and manufacturing using software solutions by providing closer …

Multi-Scale Fluid-Structure Interaction Model Analysis Of Patient-Specific Geometry For Optimization Of Lvad Outflow Graft Implantation: An Investigation Aimed At Reducing Stroke Risk, Ray Prather

Electronic Theses and Dissertations

A Left Ventricular Assist Device (LVAD), is a mechanical pump capable of providing circulatory myocardium relief when used as bridge-to-transplantation by reducing the workload of a failing heart, with the additional bonus of allowing for cardiac recovery when used as destination therapy. The newer generations of continuous flow VADs are essentially axial or radial flow pumps, and while these devices are capable their efficiency depends upon fluid composition and flow field patterns. The most devastating complication of VAD therapy is caused by embolization of thrombi formed within the LVAD or inside the heart into the brain leading to stroke. Anticoagulation …

Supporting Social Change: Administration Of Service-Learning In Communication Departments, Jennifer Snyder-Duch

Journal of the Association for Communication Administration

Service-learning has garnered wide acceptance as an effective experiential pedagogy in that it combines community service with academic instruction. This pedagogy incorporates critical, reflective thinking with personal and civic responsibility and involves students in activities that address community-identified needs. Successful service learning courses develop students’ academic skills and commitment to their community (Jacoby, 2015). Some service-learning experiences focus on advocacy or social change work. These are valuable teaching and learning experiences, but as faculty develop these courses, they must be aware of the need for departmental support.

Studies On E2 Conjugation Enzyme Partners Of Mulan E3 Ubiquitin Ligase, Rebekah J. Fitzpatrick

Honors Undergraduate Theses

Mulan is an E3 ubiquitin ligase embedded in the outer mitochondria membrane. Mulan’s participation in the ubiquitination process is conducted through its cytosol exposed RING finger domain, and its ability to modulate protein ubiquitination makes it a key player in mitochondrial and cellular homeostasis. Mulan is known to be involved in mitochondrial fission, fusion, mitochondrial stress, apoptosis, and Parkin-independent mitophagy. Dysregulation of Mulan in mice has been shown to correlate with human neurodegenerative disorders and heart disease. Accumulation of Mulan is predicted to be responsible for the motor neuron degeneration 2 (mnd2) phenotype in mutant mice through the deregulation of …

Sexual Harassment, Public Transportation, And Labor Market Outcomes For Women: Case Study Of Lahore, Pakistan, Rachel A. Wilder

Honors Undergraduate Theses

This thesis investigates an understudied question in the economics literature: how does sexual harassment experienced in and around public transportation affect labor market outcomes for women? Previous research suggests that access to public transport can improve labor market outcomes and that women's use of public transportation is sometimes limited by their experience of sexual harassment. It follows that when harassment is particularly widespread or severe – as is the case in much of South Asia – it may lead women who depend on public transportation for travel to make different labor market choices or not to work at all. If …

Gender's Role In Spanish-Language Journalism- An Examination Of How Gender Plays In Hard Vs. Soft News, Victoria R. Elajami

Honors Undergraduate Theses

The inequality of women in the workforce has been an ongoing issue. The 19th amendment granted women the right to vote in 1920. Since then, women have continued to fight for their equality in its entirety. Specifically, in the 21st-century women continue to fight for equality in the work place. Studies have shown that the amount of women in the workplace has exponentially increased. In fact, “they caught up with men in the rates of higher-education graduation, they increased their training and representation in formerly male-dominated professional fields and they entered many previously male dominated occupations” (Vokić, 2017). However the …

Can Nox1 Activity Initiate Parkinson's-Like Pathology In An Enteroendocrine Cell Line?, Evan Adler

Honors Undergraduate Theses

Increased attention has been given to the gut lately in a number of conditions, from maintaining health via the use of probiotics to treating Autism Spectrum Disorder. Parkinson's Disease has a history with the gut starting with the Braak hypothesis, in which eminent researcher Heiko Braak observed that the spread of Parkinson's (PD) seemed to occur along either olfactory or enteric neurons prior to reaching the substantia nigra in the midbrain, where the classical disease symptoms become evident. Though this finding was largely ignored at the time, the possibility of a gut origin for PD has received interest lately as …

Whose Sustainability? An Analysis Of A Community Farming Program's Food Justice And Environmental Sustainability Agenda, Sarah Davenport

Honors Undergraduate Theses

As the 1960s Environmental movement has grown, sustainability and justice discourses have come to the fore of the movement. While environmental justice discourse considers the unequal effects of environmental burdens, the language that frames "sustainability" is often socially and politically neutral. This thesis critically examines sustainability initiatives and practices of an urban farming organization in Florida. Based on ethnographic fieldwork in 2017, I explore the extent to which these initiatives incorporate race, ethnicity, and socioeconomic class when working to provide sustainably grown food in diverse communities. I argue that the organization's focus on justice for the environment, rather than for …

Optimal Sintering Temperature Of Ceria-Doped Scandia Stabilized Zirconia For Use In Solid Oxide Fuel Cells, Amanda K. Assuncao

Carbon emissions are known to cause decay of the Ozone layer in addition to creating pollutant, poisonous air. This has become a growing concern among scientists and engineers across the globe; if this issue is not addressed, it is likely that the Earth will suffer catastrophic consequences. One of the main culprits of these harmful carbon emissions is fuel combustion. Between vehicles, power plants, airplanes, and ships, the world consumes an extraordinary amount of oil and fuel which all contributes to the emissions problem. Therefore, it is crucial to develop alternative energy sources that minimize the impact on the environment. …

Exploring The Relationship Between Attitudes About Mental Illness, About Guns, And Personality Variables, Rachel N. Chavez

Honors Undergraduate Theses

This study explores relationships among attitudes about mental illness and guns in order to shed some light on two issues often mentioned in the same realm: mental illness and gun violence. This study also explores if personality variables relate to these attitudes about guns and mental illness. The results of this study found that those who reported more positive attitudes toward guns will have more negative attitudes toward mental illness. The data supported another part of the hypothesis that males would report more positive attitudes towards guns and more negative attitudes towards mental illness than females. This study did not …

Investigating The Role Of The Gut Microbiome In Huntington Disease, Casey G. Hart

Honors Undergraduate Theses

Huntington disease (HD) is an inherited neurodegenerative disease caused by a trinucleotide repeat expansion in the huntingtin (HTT) gene. Metabolic dysfunction is a feature of HD that is recapitulated in HD mouse models. Our lab has shown that circadian feeding rhythms are disrupted in humanized HD mice and restored by suppression of brain HTT. Furthermore, when circadian feeding rhythm is artificially restored, in addition to normalization of metabolic function, liver and striatal HTT is temporarily reduced, demonstrating that HTT is involved in gut-brain feedback. The gut microbiome, which can regulate gut-brain feedback, has been implicated in the pathogenesis …

Mimicking Blood Rheology For More Accurate Modeling In Benchtop Research, Lindsey Webb

Honors Undergraduate Theses

To confirm computer simulations and Computational Fluid Dynamics (CFD) analysis, benchtop experiments are needed with a fluid that mimics blood and its viscoelastic properties. Blood is challenging to use as a working fluid in a laboratory setting because of health and safety concerns. Therefore, a blood analogue is necessary to perform benchtop experiments. Viscosity is an important property of fluids for modeling and experiments. Blood is a shear thinning fluid, so it has a decreasing viscosity with higher shear rates. This project seeks to create a blood mimicking fluid for benchtop laboratory use. Numerous fluids with different combinations of water, …

Cross-Modal Distraction On Simultaneous Translation: Language Interference In Spanish-English Bilinguals, Violet A. Young

Honors Undergraduate Theses

Bilingualism has been studied extensively in multiple disciplines, yet we are still trying to figure out how exactly bilinguals think. A bilingual advantage has been observed in various experimental studies, but also has not been observed in many other studies. A bilingual advantage has been shown in tasks using selective attention. These tasks study the effects of language interference, where two types of interference are observed: interlingual (between-languages) and intralingual (within one language). This study examined language interference in Spanish-English bilinguals, using an auditory-visual simultaneous translation experimental setup. 16 college English monolinguals and 17 college Spanish-English bilinguals were tested. The …
