A Distance-Based Clustering Framework For Categorical Time Series: A Case Study In Episodes Of Care Healthcare Delivery System, Lauren Staples

Doctor of Data Science and Analytics Dissertations

Understanding how compensation structures influence overall healthcare costs is a central issue in health economics. Episodes of Care (EoC) is a compensation structure that bundles payments for healthcare interventions that belong to a well-defined health event. Since the variation of clinical pathways can drive the cost of healthcare, this research uses sequences of medical billing codes in Perinatal Episodes of Care claims data to study the extent of that variation by equating it to the number of reproducible clusters found. This research proposes a methodological framework to detect reproducible clusters in an unsupervised problem where the true number of clusters …

Advancing Cell-Free Protein Synthesis Systems For On-Demand Next-Generation Protein Therapeutics And Clinical Diagnostics, Emily Ann Long Zhao

Theses and Dissertations

Recombinant proteins have many medical and industrial applications, but their use is complicated by commercial production and stability constraints. These issues are particularly challenging for recombinant proteins used in pharmaceutical therapeutics and clinical diagnostics. Expensive production and distribution limit the accessibility of therapeutics and diagnostics especially in the developing world. Additionally, clinical use of recombinant proteins face further challenges within biological systems including biological degradation and immunogenicity. To increase the accessibility of recombinant proteins, the cost and inefficiencies of protein manufacturing and distribution need to be significantly reduced. A powerful tool to aid in this endeavor is cell-free protein synthesis …

Falling Through The Cracks Of Education: A Comparative Analysis Of Canada’S And The United States’ Use Of Standardized Testing Within The Realm Of Public Education, Micaela Baldner

University of Miami International and Comparative Law Review

The education system is foundational to society. Public education is based on the concept of equal educational opportunities for all. Although the purpose of standardized testing is the elimination of bias to prevent certain segments of society’s students from receiving unfair academic advantages, there is little empirical verification that suggests that standardized testing actually achieves its intended purpose. In fact, the evidence indicates that standardized testing negatively impacts low-income, marginalized, and English-learning students, as achievement gaps for these groups have remained the same or have even grown with the increased use of such tests. This article will discuss the intended …

A Trauma-Informed Inquiry Of Covid-19’S Initial Impact On Students In Adult Education Programs In The United States, David A. Housel

Publications and Research

The COVID-19 pandemic has had a profound impact on adult education programs throughout the world, abruptly transforming in-person instruction to distance teaching/learning. Can the lessons learned from adult students, especially related to the “digital divide,” be leveraged to enhance adult education and create more inclusive policies and practices moving forward? To grapple with this question, this exploratory qualitative study sought the insights of adult learners in the northeastern United States through an online survey of primarily open-ended questions. Through multiple rounds of coding using a trauma-informed lens, the following themes emerged: (a) anxiety and loss; (b) distractions, adjustments, and balance; …

Subject Disintegration: Identity And Alterity In The Age Of The Hyperreal, Sophie Ell

American Studies ETDs

What do the signs “identity” and “alterity” point to within the economy of representation and the logic of simulation that govern the present era? How does the visual saturation of a screen-mediated life affect the study of identity? Where does the information overload within which we operate leave the production of knowledge about otherness? My goal in this project is not to resolve these questions, but rather to linger in them. Focusing on various portrayals of categorical identities in film, photography, and digital media, I utilize a semiotic analysis to examine the formulaic, repetitive maneuvers of signification practices that reproduce …

Contextualizing Caves Within An Animate Maya Landscape: Caves As Living Agents In The Past And Present, Brent K. S. Woodfill

KIP Articles

After groundbreaking work by multiple archaeologists in the latter half of the 20th century, caves in the Maya world are currently acknowledged as fundamentally ritual rather than domestic spaces. However, a more nuanced read of the anthropological literature and conversations with Indigenous collaborators in the past and present pushes us to move still farther and see caves not as passive contexts to contain ceremonies directed elsewhere but animate beings with unique identities and personalities in their own right. This article combines archaeological, ethnohistoric, and ethnographic documentation of Maya cave use in central Guatemala to build a foundation for examining caves …

Pushing It To The Limit: Determining Asian Elephant (Elephas Maximus) Olfactory Sensitivity And Discrimination Through A Behavioral Choice Task, Matthew S. Rudolph

Theses and Dissertations

Elephants have shown remarkable olfactory capabilities. Their sense of smell impacts their foraging choices, behavior, and ultimately, survival. Being able to detect a target odor can allow elephants to locate specific resources, identify threats, and find receptive conspecifics. Previous studies have shown that elephants can consistently detect target odors, but have not identified the limits of this detection. Thus, to investigate the extent of elephants’ odor detection capabilities, we tested Asian elephants in a two-step odor discrimination task. First, we investigated whether elephants could detect odors at varying levels of dilution after a training procedure, and then whether they could …

The Influence Of Comorbid Gad On Er Utilization In Urban Youth With Asthma, David A. Karpe

Theses and Dissertations

Current literature indicates a strong association between asthma and the early onset of comorbid generalized anxiety disorder (GAD) in minors and their primary caregivers. Studies show that asthma prevalence increases with certain demographic factors, such as ethnicity, socioeconomic status, and housing quality. Evidence also suggests that GAD influences decision-making, especially when deciding to utilize emergency room (ER) services for asthma-related concerns. This study analyzed the effect of comorbid GAD on minors with asthma and ER utilization. The data were provided by an earlier Stress & Justice Study (S&J) baseline survey, an investigation aimed at understanding the impact of parental criminal …

Effects Of Catharanthine On Dopamine Release In The Nucleus Accumbens And Ethanol Consumption, Emily Baldwin

Undergraduate Honors Theses

This thesis discusses the history of catharanthine and related compounds, and their potential anti-addictive properties. Current research is exploring possible mechanisms of these properties. Past studies have found catharanthine has effects on neurons that project to the mesocorticolimbic system, an area implicated in addiction. We have seen that catharanthine decreases evoked dopamine (DA) release but increases basal DA release. This is the first study to investigate catharanthine’s effect on DA transmission in vivo. Using microdialysis, we determined the effect of catharanthine on DA in the nucleus accumbens of the striatum. This study determines the effect of different doses of …

Noise And Time Pressure Effects On Situation Awareness And Aviation Maintenance Tasks, Syaza R. M. Haris

Doctoral Dissertations and Master's Theses

Aircraft maintenance technicians (AMTs) working in a line maintenance work setting are very susceptible to the deafening occupational noise from the airport vicinity or the maintenance machinery itself. Compared to a base maintenance working period, a line maintenance job requires AMTs to complete a task within a short time frame. The current study's objective is to determine if different noise levels and time pressure influence AMTs' performance and situation awareness (SA). Sixteen Embry-Riddle Aeronautical University students majoring in Aviation Maintenance Science participated in a within-subject experimental design. Each participant's performance, SA level, and perceived workload were measured during maintenance tasks …

Energetic Tradeoffs, Infection, And Immunity In Wild Chimpanzees Of Uganda And Tanzania, Sarah Renee Phillips

Anthropology ETDs

Infectious disease is a primary source of mortality for most mammal species, but scientists have little understanding of factors driving variation in infection and immunity between individuals, populations, and species in the wild. Life history theory provides an evolutionary framework for delineating distribution of available energy to competing physiological demands, including growth, reproduction, and maintenance. Early life reproduction should be favored over late life survival, but, in long-lived species, reproductive success is strongly tied to survival to old age. Slower pace of reproduction could allow investment in immunity, reducing risk of morbidity and mortality to infectious disease. Additionally, several host …

Paleoindian Response To Climate Change In The Northern Jornada Del Muerto, Christopher Wayne Merriman

Anthropology ETDs

Human-environment interaction is a long-standing and productive line of inquiry that includes the study of cultural responses to climate change. However, demonstrating a causal relationship between climate change and the consequent culture change is rarely straightforward for numerous reasons. In this dissertation I develop an optimality model to predict how Paleoindians should have responded to changes in precipitation across the Late Pleistocene-Early Holocene. The water supply model (WSM) ranks water supplies much like the diet breadth model ranks food resources. To adjust the WSM for climate change, paleoclimate records from playas in the northern Jornada del Muerto were used in …

The core features of each subgenre are expounded. These subgenres are then evaluated using design workshops to observe novice game designs use these subgenres in their game design process. An analysis of the workshops found that the AVR subgenre framework may benefit novice game designers in …

A New Criterion For Fluoroquinolone-Associated Disability Diagnosis: Functional Gastrointestinal Disorders, Deanna N. Cannizzaro, Lydia F. Naughton, Maya Z. Freeman, Linda Martin, Charles L. Bennett M.D., Ph.D., Cecilia Bove

Faculty Publications

Background and Objectives: Fluoroquinolones (FQs) are a broad-spectrum class of antibiotics routinely prescribed for common bacterial infections despite recent recommendations to use them only for life-threatening cases. In addition to their antimicrobial properties, FQs act in the central nervous system as GABAA receptor inhibitors, which could potentially affect functionality of the vagus nerve at the forefront of gastrointestinal (GI) tract function. Alterations in neural control of digestion have been shown to be linked to Functional Gastrointestinal Disorders (FGIDs), which are usually diagnosed based on self-reported symptoms. The aim of this study was to assess the incidence of FGIDs following FQ …

Positive Influences On Why They Stay: A Qualitative Study On The Contributing Factors To Teacher Retention In Rural North Dakota, Jennifer A. Jung

Dissertations, Theses, and Projects

An alarming number of educators are leaving the field within the first five years of employment. Midwestern rural schools experience a slightly higher percentage of turnover than do their urban counterparts. Due to this shortage of teachers, many districts across the nation have employed strategies to recruit and retain competent teachers. This qualitative study employs a phenomenological approach seeking to identify common themes among teachers who are long-staying teachers in a rural district (those with 1000 or fewer students). Both the social constructivism and teacher career cycle theoretical frameworks have been utilized to support the researcher’s understanding of rural teachers' …

Expanding Occupations Through Community College Registered Apprenticeships, Anne Hoeltke

Dissertations, Theses, and Projects

ABSTRACT

Registered apprenticeships remain a key workforce strategy as an affordable pathway to secure high paying jobs and meet the changing labor market demands. Individuals who have gone through a registered apprenticeship program receive substantially higher earnings, have higher completion rates, most graduate debt free and have very high job placement rates upon completion. Yet most apprentice programs have not advanced beyond the traditional occupations (construction and advanced manufacturing), and a majority of apprentices are white males.

Community colleges have existing relationships with industry and are already central to the nation’s career and technical education which required applied learning that …
