Vulnerable Resistance In Victorian Women’S Writing, Stephanie A. Harper

USF Tampa Graduate Theses and Dissertations

This dissertation explores how socially vulnerable characters, often dismissed as lacking access to agency, create space for resistance in nineteenth-century women’s writing. Central questions the dissertation addresses are, “Why is resistance by vulnerable characters not read?” and “How are women writers encoding resistance?” Working within a comprehensive historical picture of the challenges and concerns women writers of the nineteenth century had to contend with, and informed by feminist scholarship on women writers of the nineteenth century, the dissertation looks at vulnerable characters within Charlotte Brontë’s Shirley, Elizabeth Barrett Browning’s Aurora Leigh, George Eliot’s The Mill on the Floss, and Olive …

Video Anomaly Detection: Practical Challenges For Learning Algorithms, Keval Doshi

USF Tampa Graduate Theses and Dissertations

Anomaly detection in surveillance videos is attracting an increasing amount of attention. Despite the competitive performance of several existing methods, they lack theoretical performance analysis, particularly due to the complex deep neural network architectures used in decision making. Additionally, real-time decision making is an important but mostly neglected factor in this domain. Much of the existing methods that claim to be online, depend on batch or offline processing in practice. Furthermore, several critical tasks such as continual learning, model interpretability and cross-domain adaptability are completely neglected in existing works. Motivated by these research gaps, in this dissertation we discuss our …

Are All Pictures Worth 1,000 Words? An Investigation Of Fit Between Graph Type And Performance On Accounting Data Analytics Tasks, Shawn Paul Granitto

USF Tampa Graduate Theses and Dissertations

The usefulness of accounting data is directly dependent on the presentation and interpretation of the data (DeSanctis and Jarvenpaa 1989; Brown-Liburd et al. 2015; Cao et al. 2015). While both corporate accounting and public accounting have a large focus on data analytics and visualizations, accountants in both fields have reported to have minimal experience creating visualizations and observe a growing use of visualizations within their role (Krumwiede 2019; Buchheit et al. 2020; Gibson et al. 2020). Vessey (1991) finds that the appropriateness of a visualization can impact a user’s decision-making performance. Although prior studies have provided suggestions of when to …

Complaint Patterns In Us Nursing Homes: 2013-2017, Kallol Kumar Bhattacharyya

USF Tampa Graduate Theses and Dissertations

Complaints provide valuable information to consumers about nursing homes (NHs). Complaints that are substantiated often lead to an investigation and potentially a deficiency citation. In recent years, Nursing Home Quality data show mixed results. According to some Federal reports, one of the four data sets that measure residents’ quality of care in NHs, consumer complaints, suggest that residents’ concerns over quality have increased. In contrast, the other three datasets, i.e., deficiencies through annual recertification surveys, staffing levels, and clinical quality measures, reveal potential improvement in NH quality of services. The purpose of this dissertation is to carry out analyses of …

Boredom, Interoceptive Ability, And Emotional Eating, Erica Ahlich

USF Tampa Graduate Theses and Dissertations

Emotional eating is a commonly described phenomenon reported by individuals across the weight spectrum. Not only does existing evidence suggest it is not an effective emotion regulation strategy, but emotional eating is also associated with difficulty losing weight during weight loss interventions and other negative health outcomes. The majority of existing work in the area of emotional eating has focused on the broad dimensions of negative and positive affect. Yet, there are data suggesting that different emotions appear to produce different changes in eating behaviors, suggesting the importance of investigating the influence of discrete emotions on eating. The lack of …

Alpha Synuclein: A Therapeutic Target And Biomarker For Parkinson’S Disease, Max Chase

USF Tampa Graduate Theses and Dissertations

Parkinson’s Disease is the second most common neurodegenerative disease after Alzheimer’s Disease, and the most common motor disorder. In fact, nearly a third of those with AD have PD. A major hallmark of PD is the appearance of Lewy Bodies, proteinaceous cytoplasm inclusions, that build up and spread throughout the CNS in a prion like fashion. The major component of these Lewy Bodies is a protein called alpha-synuclein. Alpha-syn is a 14kDa protein made of 140 amino acids and found in the presynaptic ends of CNS neurons, acting as a chaperone and regulator. The protein is also found in the …

Stability Analysis Of Delay-Driven Coupled Cantilevers Using The Lambert W-Function, Daniel Siebel-Cortopassi

USF Tampa Graduate Theses and Dissertations

A coupled delay-feedback system of two cantilevers can yield greater sensitivity than that of asingle cantilever system, with potential applications in atomic force microscopy. The Lambert W-function analysis concept for delay differential equations is used to more accurately model the behavior of specific configurations of these cantilever systems. We also use this analysis concept to find parameters which yield stability for greater parameter ranges, of the delay differential equations. The Q factor, or quality factor, is the ratio of energy stored in the system, to the energy lost per fixed oscillation/movement cycle. Having stability of the cantilevers corresponds to the …

A Model-Based Fault Diagnosis In Dynamic Systems Via Asynchronous Motors System Identification Or Testing, And Control Engineering Observers, Kenelt Pierre

USF Tampa Graduate Theses and Dissertations

Induction machines are the workhorse of many military and commercialtypes of equipment. They are asynchronous machines referred to in this dissertation as induction motors. They are widely used due to their reliability in Naval Unmanned Systems like Remotely Operated Vehicles (ROV), Unmanned Untethered Underwater Vehicles (UUV), Autonomous Undersea Vehicles (AUV), and platforms like Missiles and Satellites. These induction motors are mainly controlled using variable speed drive functions, i.e., thrusters, propellers, and actuators. Though they are very robust, to harness the full technical benefits of induction motors, state-of-the-art drivers or controllers must be used to control such motors.

A Comparison Of Accumulated And Distributed Reinforcer Arrangements In A Classroom, Alexandra Gingras

USF Tampa Graduate Theses and Dissertations

Though effective classroom management can increase student academic achievement and decrease disruptive behavior (e.g., Beaman & Wheldall, 2000; Marzano et al., 2003), many classroom teachers receive inadequate training on effective classroom management strategies (Reinke et al., 2011; U.S. Department of education 2000). Reinforcement-based interventions using differing reinforcer arrangements (e.g., accumulated, distributed) have been shown to be effective at reducing disruptive behavior (Fulton et al., 2019; Robinson & St. Peter, 2019); however, previous studies have not evaluated the relative efficacy of different reinforcer arrangements as teacher implemented classroom management strategies. Therefore, the purpose of this study was to assess the efficacy …

Host-Pathogen Coevolution Between Tasmanian Devils (Sarcophilus Harrisii) And Devil Facial Tumor Disease, Dylan Garret Gallinson

USF Tampa Graduate Theses and Dissertations

Coevolution is a driving force of rapid evolution, yet the complexity of coevolutionary interactions has made it difficult to characterize the genomic basis of traits mediating such relationships. Coevolutionary dynamics are especially important in host-pathogen systems where the host and pathogen must constantly adapt to one another. The Tasmanian devil and its species-specific transmissible cancer, devil facial tumor disease (DFTD), provide the rare opportunity to study host-pathogen coevolution in a complex natural system. Extensive spatiotemporal devil sampling, high linkage disequilibrium in devils, and a large selective pressure imposed by DFTD facilitate a system tractable for study. Here, we characterized devil …

Self-Perceived Assessment Of Undergraduate Leaders Competencies Through A Leadership Development Program, Ryan D. Newton

USF Tampa Graduate Theses and Dissertations

This ex-post facto research study identified changes in participants’ self-perceptions of their competence in six key leadership competencies, as reported from a pre-training and post-training self-assessment. This study also identified the relationship between the participants’ self-reported changes and their persistence in enrollment at the University upon completion of the leadership training program. This quantitative study analyzed secondary data (N=201) from a large, four-year, public research institution in the southeast United States. Paired samples t-tests were used to determine that the self-reported change among participants was statistically significant (p<.05) from the pre- to the post-training self-assessment. Further, this study then examined the relationship between participants’ self-reported mean change and their persistence at the institution, defined as having graduated or continuing enrollment one year after completion of the leadership training program. A logistic regression was utilized to identify a negative predictive relationship between participants’ mean change and their likelihood of persistence. Implications for competency-based learning were discussed in relationship to student affairs practice.
