How Some Arboreal Salamanders (Genus Aneides) Jump, Glide, And Generate Lift, Christian E. Brown

USF Tampa Graduate Theses and Dissertations

The jumping and subsequent aerial behaviors of arboreal lungless salamanders (genus Aneides) had never been investigated or described. The aims of this research were to (1) compare jumping performance within the family Plethodontidae with a special focus on arboreal species from genus Aneides, (2) describe the biomechanics and kinematics of aerial behaviors after a jump or extended fall, and (3) model airflow over the morphology of the most aerially adept salamanders to investigate if they are capable of generating lift. First, I recorded salamanders jumping, locomoting vertically, dropping, and flying in a vertical wind tunnel. Then, I laser-scanned and reconstructed …


Music As An Instructional Modality To Increase Attending Behavior Of Elementary Students, Zachary Grossman Mar 2023

Music As An Instructional Modality To Increase Attending Behavior Of Elementary Students, Zachary Grossman

USF Tampa Graduate Theses and Dissertations

Audio and audiovisual cues, when used as teaching tools, result in desirable learning outcomes for young learners when compared to visual cues alone (Havy et al., 2017; Kirkham et al., 2019; Sloutsky & Napolitano, 2003). Previous research has demonstrated that music can be an effective delivery method for teaching math in the elementary classrooms (An & Tillman, 2015; An et al., 2014; Azaryahu et al., 2020). However, the effectiveness of music at increasing attending behavior specifically has not been assessed in these studies. This study evaluated the effectiveness of music based instruction on students’ attending behaviors compared to non-music based …


The Ontological Grounds Of Reason: Psychologism, Logicism, And Hermeneutic Phenomenology, Stanford L. Howdyshell Mar 2023

The Ontological Grounds Of Reason: Psychologism, Logicism, And Hermeneutic Phenomenology, Stanford L. Howdyshell

USF Tampa Graduate Theses and Dissertations

The following dissertation explains the psychologism debate as it played out in the 19thand early 20th Centuries and then shows how Martin Heidegger radicalized the debate by undermining its key themes and assumptions. First, I explain each side of the psychologism debate, starting with the psychologicists. I explore the philosophies of Jakob Friedrich Fries and John Stuart Mill in order to encapsulate the full spectrum of psychologism in the 19th Century, from Neo-Kantian to British Empiricist. The investigation will show a set of common themes within psychologism, such as the grounding of logic in the constitution of the human subject, …


The Role Of The Dna Helicase Rrm3 Under Replication Stress, Julius Muellner Mar 2023

The Role Of The Dna Helicase Rrm3 Under Replication Stress, Julius Muellner

USF Tampa Graduate Theses and Dissertations

DNA replication needs to be strictly monitored to ensure proper duplication of the genome. During DNA synthesis, the DNA replication machinery encounters multiple obstacles such as incorrect dNTP incorporation, RNA-DNA hybrids, modification of DNA nucleobases, collision with the transcription-replication machinery. These endogenous and exogenous sources of DNA damage may result in single-strand breaks (SSBs) and double-strand DNA breaks (DSBs), thereby impeding fork progression. To prevent stalling of DNA synthesis a multitude of DNA repair pathways are specifically designed to deal with these kinds of blockages. One of the proteins involved in ensuring DNA replication fork progression is the DNA helicase …


Lithium And Lithium Isotope Behavior During High Temperature Solid/Fluid Exchanges: Examples From Iceland And The Izu-Bonin Forearc, Alex Maruszczak Mar 2023

Lithium And Lithium Isotope Behavior During High Temperature Solid/Fluid Exchanges: Examples From Iceland And The Izu-Bonin Forearc, Alex Maruszczak

USF Tampa Graduate Theses and Dissertations

The development of a method for lithium isotopic measurement was developed using a quadrupole, single-collector ICP-MS. Measured precision was ±1.00‰ 2σ over a 15-month period based on measurements of international rock standards. A 1-hour leach using cold, HCl was sufficient to remove alteration-related Li in minimally to moderately altered seafloor basalts. Measurements on the Holocene ages lavas from the neovolcanic zones of Iceland suggest no systematic Li isotopic variability among the differing Icelandic sources. Felsic samples from Hekla and Pumice contain elevated Li contents of >18ug/g while the tholeiitic and alkaline basalts are <8ug/g Li. Most of the island lies around MORB values of ~+3 to +5‰ with the exception of Western Volcanic Zone samples that show evidence for seawater inputs. The RN-17 drillcore, which penetrates >3000m through a hydrothermal system in the …


Bioinformatic Analysis Predicts Microglial Dysfunction In Murine Aging, Amadu Idrisa Jalloh Mar 2023

Bioinformatic Analysis Predicts Microglial Dysfunction In Murine Aging, Amadu Idrisa Jalloh

USF Tampa Graduate Theses and Dissertations

Age-related disease is a growing concern as the global geriatric population increases. Neurodegenerative diseases scale unfavorably in prevalence with aging and inflict disastrous consequences to human health and well-being. These disorders are challenging to investigate because they arise from complex molecular origins. The neuroimmune system is a common factor among these diseases and microglia play an important role in maintaining homeostasis in the central nervous system. Aging progressively impairs microglia by decreasing their ability to adapt and respond to noxious environmental stimuli or injury. Microglial dysfunction aggravates neurodegenerative pathology when microglia are unable to regulate neuroinflammation effectively. We investigated aging …

Conformational Dynamics And Free Energy Studies Of Dna And Other Biomolecules, Paul B. Orndorff

USF Tampa Graduate Theses and Dissertations

This work uses molecular dynamics simulations and enhanced sampling methods to investigate both the qualitative and quantitative properties of biomolecular systems. Conformational dynamics are critical in the study of biomolecular systems. Application of computer simulations to study dynamics of biomolecular systems allows for motions to be readily investigated at a resolution not possible in experimental techniques. In this work, the dynamics of uracil damaged and undamaged DNA is studied via molecular dynamics simulations. Uracil results in DNA from either misincorporation in the replication process or through spontaneous deamination of cytosine, and its presence in DNA can lead to mutations in …


An Evaluation Of Staff Management Strategies To Minimize Reactivity In Treatment Integrity Of Intervention Implementers, Claudia C. Reyes Mar 2023

An Evaluation Of Staff Management Strategies To Minimize Reactivity In Treatment Integrity Of Intervention Implementers, Claudia C. Reyes

USF Tampa Graduate Theses and Dissertations

Treatment integrity is of great importance in applied behavior analysis because of its influence on skill acquisition and behavior reduction. Staff management procedures have been assessed and found to increase levels of treatment integrity. Despite this, implementers exhibit reactivity to the presence of a supervisor with high levels of treatment integrity when supervisors are present and low levels when they are absent (e.g., Pantermuehl & Lechago, 2015). Researchers have tried to account for the effects of reactivity with limited success. The purpose of the current study was to increase treatment integrity in observer absent conditions by delivering feedback to participants …

Fuzzy Kc Clustering Imputation For Missing Not At Random Data, Markku A. Malmi Jr. Mar 2023

Fuzzy Kc Clustering Imputation For Missing Not At Random Data, Markku A. Malmi Jr.

USF Tampa Graduate Theses and Dissertations

Research has a variety of difficulties, especially when involving human subjects, and one of the most prevalent is the issue of missing data. Missing data will always be present in research due to the fact there is no perfect method for collecting data and protecting against human error or mechanical failure. This requires researchers to be able to mitigate the problems that come along with missing data; reduction in power of an analysis and bias introduced by the missing pattern. This research investigated a non-parametric method using a nested approach of fuzzy K-Modes and fuzzy C-Means clustering to impute missing …


Head Movement Behaviors In Various Communication Environments, Angkana Lertpoompunya Mar 2023

Head Movement Behaviors In Various Communication Environments, Angkana Lertpoompunya

USF Tampa Graduate Theses and Dissertations

In a complex environment with only a single-source speech target, modern hearing aids can improve signal-to-noise ratios (SNRs) by using directional microphones, and consequently, improve speech intelligibility. However, in many realistic listening situations where there are multiple sound sources, especially in a turn-taking conversation, improving the SNRs in one location may come at a cost of another equally important location. Critically, the hearing aid user is also unlikely to retain a static head orientation to which the hearing aids reference in these complex environments. For this reason, modern premium hearing aids are now equipped with motion sensors (e.g., accelerometers) to …


An Analysis Of The Oil Pollution Act Of 1990: Regulatory Calibration In Anticipation Of 21st Century Environmental Disasters, Jessica S. Thornton Mar 2023

An Analysis Of The Oil Pollution Act Of 1990: Regulatory Calibration In Anticipation Of 21st Century Environmental Disasters, Jessica S. Thornton

USF Tampa Graduate Theses and Dissertations

After federal the Oil Pollution Act of 1990 (OPA 90) was promulgated in response to the Exxon Valdez oil spill in Alaska, it helped restructure the nation’s environmental response capabilities and modernize the commercial shipping industry to effectively decrease environmental shipping disasters. However, in the 33 years since OPA 90’s inception, the oil and gas industry has transformed, especially in the offshore realm, as industry adopts new drilling technologies to gain access to deeper and heretofore untapped maritime environments. Though there have been two catastrophic offshore drilling accidents since the turn of the 21st century, OPA 90 remains categorically unchanged, …

Employing Individuals With A Criminal Record: How Prior Experience And Belief In Redeemability Impact Hiring Decisions, Kiera O'Connor

USF Tampa Graduate Theses and Dissertations

This study sought to better understand the mechanisms that play a part in employers’ hiring decisions when considering an applicant who has a criminal record. Specifically, two key variables were analyzed as a predictor of an employers’ willingness to hire (WTH): the presence and quality of an employer’s prior experience (PE) having hired an individual with a criminal record, and the extent to which they hold a belief in the redeemability (BiR) of those with a criminal record. Further, the current study aimed to contribute to the body of literature pertaining to WTH, PE and BiR by introducing BiR as …


Dreaming To Get Out The “Sunken Place”: Fantasy, Film, And The Inner-White- I(Eye), Jordan Battle Mar 2023

Dreaming To Get Out The “Sunken Place”: Fantasy, Film, And The Inner-White- I(Eye), Jordan Battle

USF Tampa Graduate Theses and Dissertations

Since its inception during the transatlantic slave trade, blackness within the collective unconscious of Western society has been sutured to negative stereotypes, images, and feelings. In modern discourse on race and racism, the unconscious manifestations of anti-black racism adopted from cultural impositions, the impact of enslavement and colonization on the psyche of the subjugated, and the importance of the mind in revolutionary efforts are all too often undertheorized. Through an Afropessimist framework, this thesis uncovers the origination of the black imago in Western society, how and why it is habitually recreated, and how black theorists, artists, political activists, and others …

Violence, Rents, And Elites: Institutional Determinants Of Political Order In Ethiopia, Rwanda, And South Sudan, Kaleb Demerew

USF Tampa Graduate Theses and Dissertations

This dissertation aims to investigate why some African states make progress in political development while others remain stagnant or regress. The study adopts a political economy approach within the new institutionalism tradition, focusing on the agency of domestic elites and the impact of violence constraints on institutional outcomes. Specifically, the study employs the violence trap framework, which identifies developing countries as fragile states, basic natural states, and mature natural states. The research applies this framework to case studies of Ethiopia, Rwanda, and South Sudan using an analytic narratives methodology that combines elite interviews with primary and secondary source analysis. The …


Healthcare Decision Makers' Perspectives On Barriers And Facilitators To Hiring Genetic Counselors In Huntington Disease (Hd) Clinic Settings, Bailey Hummel Mar 2023

Healthcare Decision Makers' Perspectives On Barriers And Facilitators To Hiring Genetic Counselors In Huntington Disease (Hd) Clinic Settings, Bailey Hummel

USF Tampa Graduate Theses and Dissertations

Huntington disease (HD) is a hereditary, neurodegenerative autosomal dominant disorder for which there are currently no effective options to prevent the onset of symptoms. Although meeting with a genetic counselor (GC) is recommended as part of national guidelines for predictive HD genetic testing and a GC is required for Centers of Excellence, not all HD centers have hired a GC. To explore drivers for, valued outcomes of, and barriers to the creation of GC positions in clinics that treat patients with HD, we conducted semi-structured interviews with 11 individuals involved with HD clinics and/or hiring decisions at 8 clinics across …

Remote Medical Diagnosis Via Infrared Thermography And Augmented Reality, Frederick M. Selkey

USF Tampa Graduate Theses and Dissertations

Fast, accurate, and non-invasive diagnostic techniques are required by the medical industry to increase the success of medical treatments and enhance the quality of patient care. Medical IRT has been demonstrated reasonably effective at diagnosing and monitoring several physiological conditions. Diversities in the human body, physical and psychological condition, measurement equipment, and environment all influence the sensitive readings obtained by passive IR measurement devices. New standards for medical IRT and fever screening have been demonstrated effective, but there is limited adherence to the guidelines [36]. Absolute temperature readings require regular calibration checks and can easily be thrown off by noise. …


"Emerging And Submerging": Silence, Commemoration, And Sexual Violence In Minneapolis, Alissa Roy Mar 2023

"Emerging And Submerging": Silence, Commemoration, And Sexual Violence In Minneapolis, Alissa Roy

USF Tampa Graduate Theses and Dissertations

Dedicated in Minneapolis in October 2020, the Survivors Memorial became the first permanent memorial to survivors of sexual violence in the United States. However, as my research reveals, sexual violence has long been a part of the commemorative landscape in northeast Minneapolis. Whereas the Survivors Memorial explicitly commemorates survivors of sexual violence, a much older site, the 1936 Pioneers Monument - commemorates sexual violence through silence. This thesis argues that with the building and dedication of the Survivors Memorial, a different memory than the one embodied within the Pioneers Monument begins to take shape. An older narrative of peaceful conquest …


The Effects Of An Interactive E-Book On Promoting Idiomatic Competence And Motivation Among L2 Learners Of Arabic Language In Saudi Arabia, Alfaifi Adel Mar 2023

The Effects Of An Interactive E-Book On Promoting Idiomatic Competence And Motivation Among L2 Learners Of Arabic Language In Saudi Arabia, Alfaifi Adel

USF Tampa Graduate Theses and Dissertations

Native Arabic speakers used idiomatic expressions such as idioms, formulas, and collocations, in their daily communications. In learning Arabic as a second language (L2), effective communication requires “the ability to understand and use idioms appropriately and accurately in a variety of sociocultural contexts, in a manner like that of native speakers, and with the least amount of mental effort” (Liontas, 2015, p. 441). Yet, promoting L2 idiomatic competence in the classroom and beyond remains a difficult task (Liontas, 2006; Tabatabaei, 2012). The utilization of e-books in the learning environment in L2 teaching in the English language has received much research …

Florida lakes are diverse ecosystems and are an important part of the state's biodiversity and ecosystem services. As human population and development increase across the state, many lakes have been documented as nutrient impaired and are unable to maintain essential ecological functions. In this study, diatom diversity and functional groups in 72 Florida lakes were assessed for their relationships with associated water-quality data. Common alpha diversity indices, including Shannon-Weiner Index, the Gini-Simpson Index, and Hill’s numbers were utilized to measure trends in diatom communities, while the relationships between diatom lifeform characteristics and environmental data were explored using multivariate methods and …


The 'Charm And Distinction' Of Proverbs: The Duality Of The Gem Analogy In Erasmus's Adagia, Blythe Broecker Creelan Mar 2023

The 'Charm And Distinction' Of Proverbs: The Duality Of The Gem Analogy In Erasmus's Adagia, Blythe Broecker Creelan

USF Tampa Graduate Theses and Dissertations

Throughout the Adagia, Erasmus of Rotterdam frequently compares proverbs to precious gems and gemstone jewelry. My interdisciplinary study contributes to the broader discussion of Erasmus’s use of imagery by evaluating the specific qualities Erasmus associates with gemstones as analogous to the qualities he argues synonymously describe proverbs, specifically how both possess and imbue “charm and distinction.” The historical use of gemstones as essential for the display of social status and political power coupled with the contemporaneous belief in amuletic and astral magical properties of gemstones reveals the complex connections Erasmus forges between the qualities of gemstones and proverbs. Erasmus’s marked …
