Skilled Workers’ Mobility And Attrition: The Case Of Florida Emergency Medicine Physicians, Vassina Hassane Meite

Theses and Dissertations

Emergency medicine (EM) physicians constitute the front line of healthcare providers. They work swiftly to address critical situations, diagnose illnesses, and stabilize patients. Amidst a growing need and shortage of EM physicians, this longitudinal descriptive study captures EM physicians’ preferences for practice locations by studying Florida EM physicians’ relocation patterns between 2006 and 2020. Esti- mates from a Cox Proportional-Hazards model and fixed effects logistic regressions suggest that wage amenities are not a strong determinant of relocation over time. Physician attrition and relocation are instead more saliently affected by high work volumes within the EM physician’s primary work location.

Seasonal Crop Foraging Habits Of Asian Elephants And The Response Of Farmers Near The Salakpra Wildlife Sanctuary, Kanchanaburi, Thailand, Scott J. Gulizio

Theses and Dissertations

The consequences of human-elephant-conflict are of concern to a range of interests, including conservation, animal welfare, and socio-economic initiatives. Loss of crops due to elephants is a particularly contentious issue and a multitude of elephant deterrents have been tried to help prevent or diminish crop-foraging. This study examines the seasonal crop-foraging habits of Asian elephants just outside of Salakpra Wildlife Sanctuary, Thailand. Specifically, we sought to analyze when the elephants would forage crops, for how long, and how farmer presence affected this behavior. Additionally, to better understand patterns of deterrent use, we cataloged which deterrents were deployed by the farmers …

Keeping Both History And Magic Alive: Judson Dance Theater: The Work Is Never Done (2018) At The Museum Of Modern Art, Beatrice M. Johnson

Theses and Dissertations

This thesis examines the exhibition, historical reconstruction, and museum acquisition and conservation of postmodern dance, with the 2018 MoMA exhibition Judson Dance Theater: The Work Is Never Done as a case study. This exhibition considered the history and legacy of 1960s postmodern dance through a presentation of artifacts and archives alongside a continuous program of live, in-gallery performances. The Work Is Never Done catalyzed questions in the three areas of dance exhibition, reconstruction, and conservation and, as this thesis argues, represents a unique example of preserving canonical dance history while creating a generative context for spontaneity, experimentation, and reinvention.

Covering The Beatles: Tribute, Tradition, And Transformation, Alexander J. Prezzano

Theses and Dissertations

This thesis focuses on cover songs as they relate to the music of The Beatles. Before and after the 1969 break-up of the band, the number of Beatles songs that have been covered by artists of various genres and in different eras is immeasurable. The implications of the cover song phenomenon of the 20th century crosses musical, cultural, political, and global borders. From the view of cover songs, this thesis will analyze The Beatles' continued influence on popular music, and the way their music has become a template, or pedagogical device for composers and songwriters in the postmodern era.

The study’s research methods were phenomenological discourse analysis and …

The Social Construction Of Sex Trafficking Among Three Agencies Seeking To Address The Problem, Alexis Lange

Theses and Dissertations

Since 2000, there has been a growing interest in human trafficking by researchers, governments, organizations, law enforcement, and the general public. One form of human trafficking that has captured the most interest and awareness is sex trafficking. However, despite the growing research and understanding of the problem, there is no shared, collective understanding and definition of sex trafficking. Various constructions and approaches have made it challenging to prevent sex trafficking, protect victims, and prosecute traffickers. For this research, I will take a social constructionist/social problems perspective by interviewing three agencies about how they identify, define, frame, and approach to the …

A Help Or Hindrance? Team Leader Behaviors And The Team Climate Of Innovation, Matthew Brady Johnson

Theses and Dissertations

While the nature of teamwork in organizations is ever-evolving, the utilization of teams in some form has continued to increase over the past several decades. While creativity is generally regarded as an individual-level phenomenon, innovation tends to occur as an emergent process at the team level, so rather than only hiring and rewarding star performers, organizations should cultivate and protect the team’s climate for innovation. A particularly impactful contextual factor in team climate is the team leader’s behavior. Therefore, the team leader’s contribution to the climate should work to promote innovation rather than discourage it. A cross-sectional, correlational study surveyed …

Simple Mechanically Reconfigurable Patch Antennas, Luis Alonso Hernandez Galvan

Theses and Dissertations

Reconfigurable antennas form an active subdivision of antenna and communications research primarily targeted at achieving reconfigurability in the RF, microwave, and millimeter-wave frequency regimes. Mechanical, all-electronic, material based, and optical methods are the most common approaches to achieve reconfigurability. Each method can overlap to create new and innovative approaches to enable device tunability. The sub-class of reconfigurable antennas are antennas that dynamically achieve an adaptable transformation of their frequency, radiation-pattern, polarization, and/or bandwidth characteristics to enable multiple dynamic functionalities.

In this thesis, we designed new rectangular and triangular microstrip patch array antennas operating in the 5G midband at 5GHz. These …

Vertical Transmission Of Zika Virus In Monodelphis Domestica, Mohini Moulick

Theses and Dissertations

Zika Viral infection in pregnant women may lead to infants born with microcephaly and other neurological complications, making Zika viral research imperative. Prior research demonstrated Monodelphis domestica to be a unique animal model for Zika virus studies, and viral proteins were detected in brain tissue of juveniles after intracerebral inoculation of infants. We wanted to determine if we can detect a viral protein, non-structural protein 1 (NS1), in brain tissue after intraperitoneal inoculation and we found it to be possible through immunohistochemistry (IHC) analysis. We also investigated if inoculated dams (mothers) would give rise to Zika positive pups (natural inoculation), …

Moreover, knowing the exact load applied to each bearing on the …

Vibration-Based Machine Learning Models For Condition Monitoring Of Railroad Rolling Stock, Sergio M. Martinez

Theses and Dissertations

One of the primary causes of rail rolling stock derailments is attributed to bearing and wheel axle failures. The health of train bearings is primarily monitored at target locations through wayside detection systems. This practice is susceptible to bearing failure and potential derailments at points in between these wayside systems. To remedy this, the University Transportation Center for Railway Safety (UTCRS) has developed a wireless onboard monitoring system that can continuously monitor the vibration response, which directly correlates to the health of bearings. This data is used to train regression-based machine learning algorithms and long-term prediction neural networks to predict …

Two Essays On Credit Risk Correlation, Theophilus Teye Osah

Theses and Dissertations

This dissertation comprises two essays on credit risk correlation. In the first essay, we provide robust empirical evidence that lenders charge higher loan spreads to borrowers with higher credit risk correlation. This effect is concentrated in investment grade firms, driven by tightening lending conditions, and more pronounced for firms with higher rollover risk. Furthermore, banks whose borrowers have higher average credit risk correlation, have greater default risk themselves. In the second paper, we find that a trading strategy that buys high- and sells low-credit risk correlation stocks generates significant risk-adjusted expected return of about 121 bps per annum. Cross-sectional regressions …
