The Happiest Place On Earth: A Grounded Theory Of Fulfillment In Mixed-Orientation Marriages, Isadora Ferreira De Melo

Electronic Theses and Dissertations

Mixed-orientation marriages (MOMs) are often misunderstood. There is a general cynicism in research literature and in the broader culture regarding the relational viability of same-sex attracted (SSA) individuals who marry someone of the opposite sex. However, there exist couples in MOMs that are resilient and attain satisfaction. The purpose of this study is to better understand how MOMs might become successful. By interviewing maritally satisfied mixed-orientation couples, the Model of Relational Self- Determination in Mixed-Orientation Marriages was developed. This model is separated into five stages that are organized around the experience of disclosure of the SSA spouse’s sexuality. Depending on …

Becoming Stewards Of Attention: A Theological Appeal, Joshua Gorenflo

Electronic Theses and Dissertations

The widespread compromising of attention currently taking place in our digital age is, at least in part, a theological issue necessitating a theological response, which invites an examination of the human person in relation to God. Familiar within the biblical narrative and throughout Christian tradition, I suggest that when the role of steward functions as the operative paradigm for humans, the claims made upon their lives have profound implications for attending within the digital age. More specifically, the steward’s attention becomes a tangible expression of authority and accountability in representation of God’s image to the rest of creation. In pursuit …

No Such Thing As A New “Normal”: The Future Of Teaching In A Pandemic World, Victoria Benard

Honors College Theses

Due to the many changes wrought on our society by the COVID-19 pandemic, teachers in high schools have had to dramatically alter their methods of teaching in order to comply with new rules and regulations. These guidelines, deemed safe by the CDC, have completely upended traditional high school classrooms and left teachers scrambling to effectively teach their content and assess student learning. The purpose of this research is to determine the successes and/or failures of high school teachers’ teaching strategies that have undergone dramatic adaptations amidst the COVID-19 pandemic. One goal of this research is to produce a concise understanding …

Sangaku In Multiple Geometries: Examining Japanese Temple Geometry Beyond Euclid, Nathan Hartmann

Honors College Theses

When the country of Japan was closed from the rest of the world from 1603 until
1867 during the Edo period, the field of mathematics developed in a different way
from how it developed in the rest of the world. One way we see this development
is through the sangaku, the thousands of geometric problems hung in various Shinto and Buddhist temples throughout the country. Written on wooden tablets by people from numerous walks of life, all these problems hold true within Euclidean geometry. During the 1800s, while Japan was still closed, non-Euclidean geometries began to develop across the …

Open Access Publications

INTRODUCTION: Early-onset scoliosis (EOS) is a well-known orthopaedic manifestation in patients with myelomeningocele. The rib-based growing system (RBGS) has been proposed as an alternative for these individuals because of the poor outcomes with traditional surgical techniques. We aimed to describe the effect of RBGS in patients with nonambulatory EOS myelomeningocele.

METHODS: We retrospectively reviewed the Pediatric Spine Study Group Multicenter Database for all patients with nonambulatory EOS myelomeningocele treated with RBGS from 2004 to 2019. Demographics, surgical data, radiographic findings, and postoperative complications were obtained. The quality-of-life parameters were assessed postoperatively using the Early-onset Scoliosis Questionnaire-24.

Open Access Publications

PURPOSE: Disparities in radiation oncology (RO) can be attributed to geographic location, socioeconomic status, race, sex, and other societal factors. One potential solution is to implement a fully mobile (FM) RO system to bring radiotherapy to rural areas and reduce barriers to access. We use Monte Carlo simulation to quantify techno-economic feasibility with uncertainty, using two rural Missouri scenarios.

METHODS: Recently, a semimobile RO system has been developed by building an o-ring linear accelerator (linac) into a mobile coach that is used for temporary care, months at a time. Transitioning to a more FM-RO system, which changes location within a …

Intelligibility Of Medically Related Sentences In Quiet, Speech-Shaped Noise, And Hospital Noise, Tessa Bent, Melissa Baese-Berk, Erica E. Ryherd, Sidney Perry

Durham School of Architectural Engineering and Construction: Faculty Publications

Noise in healthcare settings, such as hospitals, often exceeds levels recommended by health organizations. Although researchers and medical professionals have raised concerns about the effect of these noise levels on spoken communication, objective measures of behavioral intelligibility in hospital noise are lacking. Further, no studies of intelligibility in hospital noise used medically relevant terminology, which may differentially impact intelligibility compared to standard terminology in speech perception research and is essential for ensuring ecological validity. Here, intelligibility was measured using online testing for 69 young adult listeners in three listening conditions (i.e., quiet, speech-shaped noise, and hospital noise: 23 listeners per …

Expanding The Role Of Occupational Therapy For Oncology Patients: A Focus On Tumor- And Blood-Based Cancers, Erika N. Clark

Occupational Therapy Capstone Presentations

Tumor and blood-based cancer diagnosis rates are increasing rapidly in the United States. To improve survivorship, treatment practices are constantly evolving, however, patients are often left to face the consequences of survival. With decreased range of motion, strength, and ability to participate in desired activities, patients may experience a decrease in overall quality of life. Through a holistic lens, occupational therapists are well suited to address the diverse needs of cancer patients through the duration of their cancer treatments. Unfortunately, occupational therapy remains a widely underutilized service for this population. This capstone experience worked to address this gap by expanding …

Visions Of Science: An Art Historical Exploration Of Medieval Scientific Manuscripts, Olivia Brock

Undergraduate Honors Capstone Projects

The late 16th century saw a new movement in the world of science to push scientific ideas and practice out of academia and into the hands of the layman. No longer were scholars the sole proprietors of science –everyday laborers, craftsman, and artists now had practical scientific principles at their fingertips that they could incorporate into their professions. This new spread of science was facilitated in several ways, including the publication of books incorporating detailed, explanatory images, new utilitarian instruments, and public lectures. Though science was disseminated through a variety of means, I have been particularly interested in the ways …

Arseek: Identifying Api Resource Using Code And Discussion On Stack Overflow, Gia Kien Luong, Mohammad Hadi, Thung Ferdian, Fatemeh H. Fard, David Lo

Research Collection School Of Computing and Information Systems

It is not a trivial problem to collect API-relevant examples, usages, and mentions on venues such as Stack Overflow. It requires efforts to correctly recognize whether the discussion refers to the API method that developers/tools are searching for. The content of the Stack Overflow thread, which consists of both text paragraphs describing the involvement of the API method in the discussion and the code snippets containing the API invocation, may refer to the given API method. Leveraging this observation, we develop ARSeek, a context-specific algorithm to capture the semantic and syntactic information of the paragraphs and code snippets in a …

Exais: Executable Ai Semantics, Richard Schumi, Jun Sun

Research Collection School Of Computing and Information Systems

Neural networks can be regarded as a new programming paradigm, i.e., instead of building ever-more complex programs through (often informal) logical reasoning in the programmers' mind, complex 'AI' systems are built by optimising generic neural network models with big data. In this new paradigm, AI frameworks such as TensorFlow and PyTorch play a key role, which is as essential as the compiler for traditional programs. It is known that the lack of a proper semantics for programming languages (such as C), i.e., a correctness specification for compilers, has contributed to many problematic program behaviours and security issues. While it is …

Press A To Jump: Design Strategies For Video Game Learnability, Lev Poretski, Anthony Tang

Research Collection School Of Computing and Information Systems

Learnability is a core aspect of software usability. Video games are not an exception, as game designers need to teach players how to play their creations. We analyzed 40 contemporary video games to identify how video games approach learning experiences. We found that games have advanced far beyond using simple tutorials or demonstration screens and adopt a range of repeatable and reusable design strategies using visual cues to facilitate learning. We provide a detailed descriptive framework of these design strategies, elucidating how and when they can be used, and describing how the visual cues are used to build them. Our …

Undiscounted Recursive Path Choice Models: Convergence Properties And Algorithms, Tien Mai, Emma Frejinger

Research Collection School Of Computing and Information Systems

Traffic flow predictions are central to a wealth of problems in transportation. Path choice models can be used for this purpose, and in state-of-the-art models—so-called recursive path choice (RPC) models—the choice of a path is formulated as a sequential arc choice process using undiscounted Markov decision process (MDP) with an absorbing state. The MDP has a utility maximization objective with unknown parameters that are estimated based on data. The estimation and prediction using RPC models require repeatedly solving value functions that are solutions to the Bellman equation. Although there are several examples of successful applications of RPC models in the …

Defining The Collapse Point In Colloidal Unimolecular Polymer (Cup) Formation, Ashish Zore, Peng Geng, Yuwei Zhang, Michael R. Van De Mark

Chemistry Faculty Research & Creative Works

Colloidal unimolecular polymer (CUP) particles were made using polymers with different ratios of hydrophobic and hydrophilic monomers via a self-organization process known as water reduction. The water-reduction process and the collapse of the polymer chain to form a CUP were tracked using viscosity measurements as a function of composition. A vibration viscometer, which allowed for viscosity measurement as the water was being added during the water-reduction process, was utilized. The protocol was optimized and tested for factors such as temperature control, loss of material, measurement stability while stirring, and changes in the solution volume with the addition of water. The …

With the developed virtual tracer technique, liquid and solids back mixing was investigated at the conditions mimicking Fischer-Tropsch synthesis. Experiments were conducted at different pressure, solids loading, and superficial gas velocity. The axial dispersion model (ADM) and recirculation and cross flow dispersion (RCFD) models were used to model the liquid mixing. Transient sedimentation dispersion model …

Review Of Biomechanical Studies And Finite Element Modeling Of Sternal Closure Using Bio-Active Adhesives, Amatulraheem Al-Abassi, Marcello Papini, Mark R. Towler

Chemical and Biochemical Engineering Faculty Research & Creative Works

The most common complication of median sternotomy surgery is sternum re-separation after sternal fixation, which leads to high rates of morbidity and mortality. The adhered sternal fixation technique comprises the wiring fixation technique and the use of bio-adhesives. Adhered sternal fixation techniques have not been extensively studied using finite element analysis, so mechanical testing studies and finite element analysis of sternal fixation will be presented in this review to find the optimum techniques for simulating sternal fixation with adhesives. The optimal wiring technique should enhance bone stability and limit sternal displacement. Bio-adhesives have been proposed to support sternal fixation, as …

Queens Of Discourse: An Observation Of Black Insta-Comediennes, Naoka Foreman

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study observed the ways Black females on Instagram perform sociopolitical humor online to push back against the dominant culture in this digital age – maintaining the Black comedy tradition. It explores and illuminates the strategies of resistance exhibited by Instagram comediennes through a textual analysis informed by minor discourse, intersectionality, and critical feminist theories. Each comic’s personae were investigated and their content on Instagram was randomly selected and coded then grouped into themes. Black insta-comediennes shared Black feminist thought, modified beliefs about Black females or conventionality, and negotiated with the industrial demands of show business to earn subjectivity on …
