Multimodal Learning: Generating Precise Chest X-Ray Report On Thorax Abnormality, Gaurab Subedi

Dissertations and Theses

Chronic respiratory diseases, ranking as the third leading cause of death worldwide according to the 2017 World Health Organization (WHO) report, affect a staggering 544.9 million individuals. Compounding this public health challenge is the fact that over 80% of health systems grapple with shortages in their radiology departments, highlighting an urgent need for accessible and efficient diagnostic solutions. While various image classification models for analyzing thorax abnormalities have been developed, relying solely on one type of dataset (image data, for example) for thorax abnormality analysis is insufficient. Integrating texts with image data could provide more accuracy as well as analysis. …

Induction And Mentoring Programs: Pathways To New Teacher Retention And Success, Valerie Kim Seales

Dissertations and Theses

The pipeline of college students seeking teaching positions is shrinking. The teacher shortage makes finding and retaining new teachers even more challenging. The cost of replacing existing teachers who leave is tremendous, and new teachers leave the profession at an alarming rate. This dissertation explored the lived experiences of new teachers who recently completed their induction and mentoring program. The study addresses three primary research questions: (1) What are the perceived benefits and deficits of the induction program (2) What (if any) additional support do new teachers need to improve their work experience in our schools? Using a phenomenological research …

Soft System Methodology Applied To Stakeholder Engagement In Social Services Nonprofit Organizations, Robyn Chin

Full-Text Theses & Dissertations

This dissertation explored the challenges of a Community Development Financial Institution (CDFI), a non-profit social service organization, and the value of employing a systems thinking approach to problem formulation and problem-solving to address its challenges. Soft Systems Methodology (SSM), a systems-informed framework, encourages collective learning and fosters an appreciation for differing perspectives about problem formulation amongst stakeholders instead of rushing to solve predefined issues. One common challenge from current research is that due to reliance on sparse profits and grants earmarked for programmatic endeavors, there is insufficient funding for organizational development. The literature also identified a deficit in stakeholder engagement …

$\Ast$-Semiclean Rings, Shefali Gupta, Dinesh Udar

Turkish Journal of Mathematics

A ring $R$ is called semiclean if every element of $R$ can be expressed as sum of a periodic element and a unit. In this paper, we introduce a new class of ring, which is the $\ast$-version of the semiclean ring, i.e. the $\ast$-semiclean ring. A $\ast$-ring is $\ast$-semiclean if each element is a sum of a $\ast$-periodic element and a unit. The term $\ast$-semiclean is a stronger notion than semiclean. In this paper, many properties of $\ast$-semiclean rings are discussed. It is proved that if $p \in P(R)$ such that $pRp$ and $(1-p)R(1-p)$ are $\ast$-semiclean rings, then $R$ is …

Methodologies For Evaluating Interaction Cues For Virtual Reality, Xinyu Hu

Electronic Theses and Dissertations, 2020-2023

Virtual reality (VR) games and educational systems commonly employ interaction cues to provide information on how to take appropriate actions at particular moments. Interaction cues can be employed for different purposes, such as informing the user to look, go, pick, and operate. Additionally, different types of interaction cues can directly affect usability and user experiences. In our early research, we conducted two ecologically valid empirical studies with a preexisting VR training application and evaluated the effects of delayed interaction cues, in addition to comparing the purposes of interaction cues for learning and retention. Our results indicated that immediate interaction cues …

From Human Behavior To Machine Behavior, Zerong Xi

Electronic Theses and Dissertations, 2020-2023

A core pursuit of artificial intelligence is the comprehension of human behavior. Imbuing intelligent agents with a good human behavior model can help them understand how to behave intelligently and interactively in complex situations. Due to the increase in data availability and computational resources, the development of machine learning algorithms for duplicating human cognitive abilities has made rapid progress. To solve difficult scenarios, learning-based methods must search for solutions in a predefined but large space. Along with implementing a smart exploration strategy, the right representation for a task can help narrow the search process during learning. This dissertation tackles three …

Comparing Phosphorus Removal Efficiencies And Mechanisms Via Two Cost-Effective Specialty Adsorbents In A Cascade Upflow Filtration System, Sydney Kilgus-Vesely

Honors Undergraduate Theses

Finding solutions to treat water that contains phosphorus is an important effort due to the harmful impacts it presents to both human health and the environment. Phosphorus is considered a limiting factor in water oftentimes and therefore controls the growth of algal bloom in a water body. The increase of algal populations due to wastewater effluent, stormwater runoff, and agricultural discharge in Florida waters has a direct link to the event of harmful algal blooms such as red tide in coastal regions, eutrophication of waterbodies, and fish kills. Finding low cost, energy efficient, and low maintenance green sorption media (GSM) …

A Framework For The Automatic Identification Of Optimized Yield Surface Parameters, Kevin Hanekom

Honors Undergraduate Theses

Advanced engineering materials are designed to display tensile-compressive asymmetry (TCA) and anisotropy to provide unique attributes to critical components necessary in the hot section of turbines. The never-ending chase for higher efficiencies, and with them, higher temperature gradients, intrinsically leads to more and more of these complex materials, like single crystal turbine blades, embedded within the turbine environment. Mathematical models, known as yield criteria, allow engineers to visualize the mechanical behavior of these materials in various orientations under complex loading. Yield criteria are dependent on three key items in determination of their governing parameters: material test data, mathematical constraints, and …

Much attention has been given to active learning strategies to promote student engagement and content retention, yet little information exists regarding student preferences for in higher level graduate nursing courses. This mixed-methods study aimed to examine student learning preferences for seven different instructional methodologies; traditional lecture, a problem-based learning exercise, reading with workbook assignments, development of cognitive aids, game-based learning, practice questions, and a case …

Magnetotelluric Insights Into The Formation And Reactivation Of Trans-Crustal Shear Zones In Precambrian Basement Of The Eastern U.S. Midcontinent, Benjamin S. Murphy, Michael S. Delucia, Stephen Marshak, Dhananjay Ravat, Paul A. Bedrosian

Earth and Environmental Sciences Faculty Publications

Three-dimensional inversion of regional long-period magnetotelluric (MT) data re- veals the presence of two distinct sets of high-conductivity belts in the Precambrian basement of the eastern U.S. Midcontinent. One set, beneath Missouri, Illinois, Indiana, and western Ohio, is defined by northwest– southeast-oriented conductivity structures; the other set, beneath Kentucky, West Vir- ginia, western Virginia, and eastern Ohio, in- cludes structures that are generally oriented northeast–southwest. The northwest-trend- ing belts occur mainly in Paleoproterozoic crust, and we suggest that their high con- ductivity values are due to graphite precipi- tated within trans-crustal shear zones from intrusion-related CO2-rich fluids. Our MT inversion …

Terrestrial Ecosystem Transformations In Response To Rapid Climate Change During The Last Deglaciation Around Mono Lake, California, Usa, Adam J. Benfield, Sarah J. Ivory, Bailee Nicole Hodelka, Susan R. H. Zimmerman, Michael M. Mcglue

Earth and Environmental Sciences Faculty Publications

We examine major reorganizations of the terrestrial ecosystem around Mono Lake, California during the last deglacial period from 16,000–9,000 cal yr BP using pollen, microcharcoal, and coprophilous fungal spores (Sporormiella) from a deep-water sediment core. The pollen results record the assemblage, decline, and replacement of a mixed wooded community of Sierran and Great Basin taxa with Alkali Sink and Sagebrush Steppe biomes around Mono Lake. In particular, the enigmatic presence of Sequoiadendron-type pollen and its extirpation during the early Holocene hint at substantial biogeographic reorganizations on the Sierran-Great Basin ecotone during deglaciation. Rapid regional hydroclimate changes produced structural alterations in …

Microtubule Polarity Flaws As A Treatable Driver Of Neurodegeneration, Bridie D. Eckel, Roy Cruz Jr., Erin M. Craig, Peter W. Baas

All Faculty Scholarship for the College of the Sciences

Microtubule disruption is a common downstream mechanism leading to axonal degeneration in a number of neurological diseases. To date, most studies on this topic have focused on the loss of microtubule mass from the axon, as well as changes in the stability properties of the microtubules and/or their tubulin composition. Here we posit corruption of the normal pattern of microtubule polarity orientation as an underappreciated and yet treatable contributor to axonal degeneration. We include computational modeling to fortify the rigor of our considerations. Our simulations demonstrate that even a small deviation from the usual polarity pattern of axonal microtubules is …

Eocene To Oligocene Cooling And Ice Growth Based On The Geochemistry Of Interglacial Mudstones From The East Antarctic Continental Shelf, Jennifer J. Light, Sandra Passchier

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

The Eocene-Oligocene Transition at c. 34 million years ago (Ma) marked the global change from greenhouse to icehouse and the establishment of the East Antarctic Ice Sheet (EAIS). How the ice-sheet behaviour changed during interglacials across this climate transition is poorly understood. We analysed major, trace and rare earth elemental data of late Eocene interglacial mudstone from Prydz Bay at Ocean Drilling Program Site 1166 and early Oligocene interglacial mudstone from Integrated Ocean Drilling Program Site U1360 on the Wilkes Land continental shelf. Both sites have comparable glaciomarine depositional settings. Lithofacies and provenance at Site 1166 in Prydz Bay are …

Indigenous And Western Sciences In Carlos Hernandez's The Assimilated Cuban's Guide To Quantum Santeria, Joy Sanchez-Taylor

Publications and Research

This chapter examines Carlos Hernandez’s The Assimilated Cuban’s Guide to Quantum Santeria as an example of how authors of alternative futurisms can draw on Indigenous knowledge to destabilize Eurowestern perceptions that Western science is more modern and rational than Indigenous knowledge. Joy Sanchez-Taylor argues that Hernandez combines references to Santería and quantum physics to demonstrate parallels between Indigenous knowledge and Eurowestern “rational” science. Ultimately, references in Quantum Santeria to ideas of spiritual healing and nonlinear time demonstrate how authors like Hernandez are working to restore Biskaabiiyang, or a return to self, within science fiction.

Modeling Monthly Actual Evapotranspiration: An Application Of Geographically Weighted Regression Technique In The Passaic River Basin, Felix Oteng Mensah, Clement Aga Alo

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Actual evapotranspiration (ET) is perhaps the most difficult quantity to directly measure among the major water balance components. Because of the high cost and labor constraints associated with the direct measurement of ET, empirical data-driven modeling has frequently been used to estimate ET. Beyond the widely used traditional type regression that has the effect of producing ‘global’ parameter estimates, assumed to be uniform throughout an area, we utilized a more localized spatially non-stationary technique - the geographically weighted regression (GWR) - to estimate mean monthly ET in the Passaic River Basin (PRB). We identified the key environmental controls of ET …
