Clinical Evaluation Of An Auto-Segmentation Tool For Spine Sbrt Treatment., Yingxuan Chen, Yevgeniy Vinogradskiy, Yan Yu, Wenyin Shi, Haisong Liu

Department of Radiation Oncology Faculty Papers

Purpose: Spine SBRT target delineation is time-consuming due to the complex bone structure. Recently, Elements SmartBrush Spine (ESS) was developed by Brainlab to automatically generate a clinical target volume (CTV) based on gross tumor volume (GTV). The aim of this project is to evaluate the accuracy and efficiency of ESS auto-segmentation.

Methods: Twenty spine SBRT patients with 21 target sites treated at our institution were used for this retrospective comparison study. Planning CT/MRI images and physician-drawn GTVs were inputs for ESS. ESS can automatically segment the vertebra, split the vertebra into 6 sectors, and generate a CTV based on the …

Faculty Perceptions Of Nursing Student Retention In Community College Associate Degree Programs: A Qualitative Descriptive Study, Lauri Jones

Dissertations

Understanding the factors that influence nursing students to stay or leave a nursing program is vital to ensure our population has prepared nurses to care. Low student retention leads to fewer nurse graduates, negatively impacting the nursing shortage. Although several factors contribute to the nursing shortage, with many well beyond the influence of nursing education programs, student retention is a factor where nurse educators can play a pivotal role. Research indicates that students perceive faculty relationships as influential to their success, satisfaction and retention in education programs. However, a gap in the literature exists on faculty perspectives of student retention, …

Examining The Relationship Between Therapists’ Attachment-Related Characteristics And The Process And Outcome Of Psychotherapy, Char M. Houben

Dissertations

Although psychotherapy researchers have gleaned greater understanding about how client attachment classifications influence the outcome of psychotherapy, relatively few studies have investigated therapists’ effects and have yielded inconclusive results (Steel et al., 2018). In the current study, we investigated how therapist attachment affects changes in the working alliance and client psychological distress over a course of psychotherapy treatment. We evaluated attachment in a sample of 23 therapist trainees from a university-based training clinic in the U.S. with the recently validated, transcript-based Therapist Attunement Scales (TASc; Talia & Muzi, 2017), which measures attunement by moment-to-moment discursive markers from a single psychotherapy …

Divergent Water Requirements Partition Exposure Risk To Parasites In Wild Equids, Kaia J. Tombak, Laurel A. Easterling, Lindsay Martinez, Monica S. Seng, Liana F. Wait, Daniel I. Rubenstein

Publications and Research

For grazing herbivores, dung density in feeding areas is an important determinant of exposure risk to fecal- orally transmitted parasites. When host species share the same parasite species, a nonrandom distribution of their cumulative dung density and/or nonrandom ranging and feeding behavior may skew exposure risk and the relative selection pressure parasites impose on each host. The arid-adapted Grevy's zebra ( Equus grevyi ) can range more widely than the water-dependent plains zebra ( Equus quagga ), with which it shares the same species of gastrointestinal nematodes. We studied how the spatial distribution of zebra dung relates to ranging and …

The Role Of Chemical Cues In Host Susceptibility To Fish-Parasitic Gnathiid Isopods., Clayton M. Vondriska

Student Theses and Dissertations

Parasitism is one of the most common lifestyle strategies. Ectoparasites must navigate complex environments to find their host and many rely heavily on chemical cues to do so. Gnathiid isopods are common parasites that use chemical cues to find their marine fish hosts. While gnathiids are considered host-generalists, hosts vary in their susceptibility to infestation. However, the mechanisms that mediate differential susceptibility are unknown. Here I used field and laboratory experiments to investigate if the chemo-attractiveness of hosts explains differences in susceptibility of Caribbean reef fishes to infestation by a common Caribbean gnathiid isopod, Gnathia marleyi. While G. marleyi can …

Source Of Off-Type Frequencies In Winter Wheat Varieties, Michaela Benes

Honors Program: Senior Projects (Public)

The enzyme polyphenol oxidase (PPO) is undesirable in most wheat products due to the discoloration it causes. Purifying wheat varieties through selective breeding is the best way at getting rid of PPO in a variety. The variety NW15443 was planted in both a field in McCook, NE, and in a greenhouse in Lincoln, NE. Individual heads were snapped from the field and the greenhouse seed was harvested in bulk. After completing a PPO test of the seed, it was determined that the percentages of off-type frequencies from the field seed and the greenhouse seed were 11% and 3.6%, respectively. Using …

The Impact Of Teacher And Student Racial And Ethnic Matching On Student Outcomes: A Quantitative Study, Daryl Minus-Vincent

Seton Hall University Dissertations and Theses (ETDs)

This study aimed to investigate the predictive relationship of teacher race on student outcomes in New Jersey public schools, as measured by the New Jersey Student Learning Assessment (NJSLA), chronic absenteeism, and graduation rates. Specifically, the relationship between teacher and student race matching with Black students, the schoolwide population of students, and a subset of urban schools was examined. The study investigated the potential of race matching to address the problem of racial and ethnic student achievement gaps. Studies indicate that pairing students with teachers with whom they share the same race and ethnicity can lead to increased cultural understanding …

The Development And Validation Of A Universal Enjoyment Measure: The Enjoy Scale, Joseph Keebler, Tianxin Zhang, Barbara Chaparro, Christina M. Frederick, Shayn S. Davidson, James Szalma

Publications

For decades, the concept of enjoyment has been used to measure the psychological benefits of activities and has been shown to determine future behavior toward activities and objects of interest. However, there has been little consensus on the definition and dimensionality of enjoyment. This study introduced a new measure of enjoyment with scale development and validation reported. CFA and EFA findings from 1466 participants across 739 different activities were reported. The instrument developed measured enjoyment across activities, with demonstrated content validity, internal consistency, discriminant and convergent validity. The final 25-item version of the ENJOY scale is composed of 5 factors: …

Evaluation Of Hydrodynamic Effects Of Waterway Restoration On An Estuarine Ecosystem, Megan Kramer

USF Tampa Graduate Theses and Dissertations

Estuaries are hydrodynamically complex for they are influenced by tidal forces, freshwater flows, salinity variations, and often intricate coastal land morphology. Furthermore, many estuaries are subject to constant anthropogenic stresses due to dense coastal populations, which are expected to be exacerbated by changing climate trends. The 1,800 home residential Manchester Waterway (MW) community located in Charlotte Harbor (along the Gulf of Mexico in Southwest Florida), is interested in improving boat access by restoring a previous connection between the local waterway and the harbor, separated by a barrier peninsula. The proposed connections aim to reduce boat traffic and travel time through …

Investigations Into The Improvement Of Angelman Syndrome Therapeutics, Austin W. Nenninger

USF Tampa Graduate Theses and Dissertations

Angelman syndrome (AS) is a rare genetic neurodevelopmental disease caused by interruption of the function of the ubiquitin ligase UBE3A gene. Patients experience an early life onset of symptoms which include pronounced intellectual disability, drastic speech impairmentor inability to speak, severe movement disorders, seizures, aggression, disruptive sleep impairment, and unusual personality traits. Estimates of prevalence show that approximately 1:15000 births are affected.

The disease is severe, and the burden can be devastating to the patients and the caregivers that they require for the duration of their relatively normal lifespan. Current treatments for the disease are lacking. Many are expensive and …

Impact Of Arginine Metabolism And Sensing In Mouse Models Of Alzheimer’S Disease, Chao Ma

USF Tampa Graduate Theses and Dissertations

Alzheimer’s disease (AD) remains the most common neurodegenerative disease in the central nervous system (CNS), with amyloidosis and tauopathy as their two main hallmarks. Typical AD pathologies include cerebral plaques deposited by amyloid-β, neurofibrillary tangles aggregated by tau, and neuroinflammation caused by activated brain myeloid cells. A critical theme is centered on impaired brain metabolism. Emerging evidence showed that impaired arginine metabolism was a novel biomarker pathway for AD. The manipulation of arginine metabolism by a critical enzyme arginase 1 (ARG1) in neurons indicated therapeutic benefits in alleviating tau pathology. Balanced cellular proteostasis was governed by the mechanistic target of …

Down Syndrome-Associated Arthritis (Da): Diagnostic And Management Challenges., Jordan T. Jones, Jacqueline Kitchen, Nasreen Talib

Manuscripts, Articles, Book Chapters and Other Papers

Down syndrome (DS) is one of the most common birth defects in the United States, the most common genomic disorder of intellectual disability, and results from trisomy 21. This chromosome disorder causes an extensive, heterogenous phenotype that results in a broad presentation of symptoms that includes atlantoaxial instability, congenital heart defects, muscle hypotonia, hypothyroidism, hematologic disorders, recurrent infections, and autoimmune diseases. The autoimmune diseases are caused by immune system dysregulation that results in increased pro-inflammatory cytokines, along with other innate and adaptive immune system dysregulation. This is the likely cause of the increased risk of inflammatory arthritis or Down syndrome-associated …

Subaerial Volcanism Is A Potentially Major Contributor To Oceanic Iron And Manganese Cycles, Jack Longman, Martin R. Palmer, Thomas M. Gernon, Hayley R. Manners, Morgan T. Jones

School of Geography, Earth and Environmental Sciences

Surface ocean availability of the micronutrients iron and manganese influences primary productivity and carbon cycling in the ocean. Volcanic ash is rich in iron and manganese, but the global supply of these nutrients to the oceans via ash deposition is poorly constrained. Here, we use marine sediment-hosted ash composition data from ten volcanic regions, and subaerial volcanic eruption volumes, to estimate global ash-driven nutrient fluxes. Using Monte Carlo simulations, we estimate average fluxes of dissolved Iron and Manganese from volcanic sources to be between 50 and 500 (median 180) and 0.6 and 3.2 (median 1.3) Gmol yr−1, respectively. Much of …

Revisiting The Dual Pathway Hypothesis Of Chorismate Production In Plants, Joseph H. Lynch

Faculty & Staff Scholarship

The shikimate pathway, the seven enzymatic steps that synthesize chorismate from phosphoenolpyruvate and erythrose 4-phosphate, produces the last common precursor of the three aromatic amino acids. It is firmly established that all seven enzymes are present in plastids, and it is generally accepted that this organelle is likely the sole location for production of chorismate in plants. However, recently a growing body of evidence has provided support for a previous proposal that at least portions of the pathway are duplicated in the cytosol, referred to as the Dual Pathway Hypothesis. Here I revisit this obscure hypothesis by reviewing the findings …

Despite their enormous size, whales make their living as voracious predators. To catch their much smaller, more maneuverable prey, they have developed several unique locomotor strategies that require high energetic input, high mechanical power output and a surprising degree of agility. To better understand how body size affects maneuverability at the largest scale, we used bio-logging data, aerial photogrammetry and a high-throughput approach to quantify the maneuvering performance of seven species of free-swimming baleen whale. We found that as body size increases, absolute maneuvering performance decreases: larger whales use lower accelerations and perform slower pitch-changes, rolls and turns than smaller …

Whales In The Carbon Cycle: Can Recovery Remove Carbon Dioxide?, Heidi C. Pearson, Matthew S. Savoca, Daniel P. Costa, Michael W. Lomas, Renato Molita, Andrew J. Pershing, Craig R. Smith, Juan Carlos Villaseñor-Derbez, Stephen R. Wing, Joe Roman

Faculty, Staff, and Students

The great whales (baleen and sperm whales), through their massive size and wide distribution, influence ecosystem and carbon dynamics. Whales directly store carbon in their biomass and contribute to carbon export through sinking carcasses. Whale excreta may stimulate phytoplankton growth and capture atmospheric CO2; such indirect pathways represent the greatest potential for whale-carbon sequestration but are poorly understood. We quantify the carbon values of whales while recognizing the numerous ecosystem, cultural, and moral motivations to protect them. We also propose a framework to quantify the economic value of whale carbon as populations change over time. Finally, we suggest research to …

Health Risk From Toxic Metals In Wild Rice Grown In Copper Mining-Impacted Sediments, Rohan Deep Sarkar, Zhiming Zhang, Manas Warke, Rupali Datta

Michigan Tech Publications, Part 1

Northern wild rice is of great dietary and cultural importance to the Native American population in the Upper Peninsula of Michigan. Millions of tons of mine tailings were discharged into Lake Superior and other inland lakes during the copper mining boom in the early 20th century in this area. This includes L’Anse Bay, located within the Keweenaw Bay Indian Community (KBIC) reservation. Since wild rice restoration is being encouraged by the KBIC, we investigated the distribution of toxic metals in sediments, water, and wild rice and their potential impact on human health from two locations. Sand Point sloughs on L’Anse …

Has Feminism Changed Women’S Realities In Africa? An Interrogation Of The Poems Of Ogundipe And Shire, Edith Weseja Bwana

Journal of Humanities and Social Sciences

African feminist movements of the 1960’s marked the starting point of debates from the origin of feminism in Africa to its impact on women and the society at large. Literature has from the go been used as a vehicle to reflect the life and its vicissitude on African women. African women writers have used literature as a platform to challenge and re-imagine gender relations within their societies and the continent as a whole. Yet, the question arises: despite half a century’s worth of literary production, has the reality of women, as reflected in literature, changed? This paper thematically interrogates the …

Sexism In Tanzanian Secondary School English Language Textbooks: Investigation Of Adjective Attributions, Fides S. Pangani, Antoni Keya Antoni Keya

Journal of Humanities and Social Sciences

This research paper investigates sexism in Tanzania’s secondary school English language textbooks with a focus on the adjectives used to describe women and men in textbooks published between 2005 and 2014. The paper aims to reveal how women and men are described, uncover gender ideologies conveyed by adjective descriptions and characterise the gender ideologies as hegemonic or deviant. Data were collected through a critical textual review of eight (8) textbooks. This paper is anchored on the Feminist CDA theory; and Fairclough’s three-dimensional framework was used as the analytic tool whereby data were described, interpreted and explained. The findings indicate that …

Activity Budgets Of Inland Versus Coastal Larus Argentatus Populations In Maine, Rebecca Cusick, Cassie Ferri

Undergraduate Research (Journal)

Comparing the behavior of wildlife populations residing in different habitats can give insight into external factors that influence behavior and explain why certain behaviors are exhibited by a species. In this study, we compared the average activity budgets of Herring Gulls (Larus argentatus) residing around inland and coastal habitats. We hypothesized that gulls in inland settings would be more likely to exhibit inactive behaviors such as loafing and sleeping, while gulls in coastal settings would exhibit more active behaviors such as foraging, walking, and squabbling. We observed a total of 100 individual gulls throughout the state of Maine, with 50 …
