Early detection of health changes in the elderly using in-home multi-sensor data streams
Authors:   , Wu Wenlong
Published: September 2022

The rapid aging of the population worldwide requires increased attention from health care providers and the entire society. For the elderly to live independently, many health issues related to old age, such as frailty and risk of falling, need increased attention and monitoring. When monitoring daily routines for older adults, it is desirable to detect the early signs of health changes before serious health events, such as hospitalizations, happen, so that timely and adequate preventive care may be provided. By deploying multi-sensor systems in homes of the elderly, we can track trajectories of daily behaviors in a feature space defined using the sensor data. In this work, we investigate a methodology for learning data distribution from streaming data and tracking the evolution of the behavior trajectories over long periods (years) using high dimensional streaming clustering and provide very early indicators of changes in health. If we assume that habitual behaviors correspond to clusters in feature space and diseases produce a change in behavior, albeit not highly specific, tracking trajectory deviations can provide hints of early illness. Retrospectively, we visualize the streaming clustering results and track how the behavior clusters evolve in feature space with the help of two dimension-reduction algorithms, Principal Component Analysis (PCA) and t-distributed Stochastic Neighbor Embedding (t-SNE). Moreover, our tracking algorithm in the original high dimensional feature space generates early health warning alerts if a negative trend is detected in the behavior trajectory. We validated our algorithm on synthetic data, real-world data and tested it on a pilot dataset of four TigerPlace residents monitored with a collection of motion, bed, and depth sensors over ten years. We used the TigerPlace electronic health records (EHR) to understand the residents' behavior patterns and to evaluate and explain the health warnings generated by our algorithm. The results obtained on the TigerPlace dataset show that most of the warnings produced by our algorithm can be linked to health events documented in the EHR, providing strong support for a prospective deployment of the approach.
Ecology of mid-continent migratory shorebirds, performance of tracking devices, and modelling animal social structure and demography
Authors:   , Clements Sarah Jeanne
Published: September 2022

[EMBARGOED UNTIL 6/1/2023] Migratory birds are threatened by landscape and climate change, and shorebirds are particularly imperiled. Shorebirds undertake some of the most impressive migrations in the world, but in every season, there are threats such as habitat loss, limited prey abundance, overhunting, and climate change contributing to their declines. New technologies and analytical techniques offer opportunities to improve our ability to disentangle drivers of shorebird declines to inform conservation investments. However, it is important to test and evaluate new technologies and methods to move toward the most cost-effective and least invasive ways to gather necessary information. The chapters of my dissertation were: (1) studying environmental drivers of migration decision-making and reproductive success in black-bellied plovers (Pluvialis squatarola); (2) examining spatial and temporal habitat characteristics that influence energy expenditure and behavior in American avocets (Recurvirostra americana); (3) characterizing and comparing migration strategies among three species with contrasting life histories: American avocets, black-bellied plovers, and Hudsonian godwits (Limosa haemastica); (4) testing performance of tracking devices for bird research; and (5) developing and evaluating a modelling approach to combine social structure and survival information. In chapter 1, we found that winter and spring weather conditions influenced migration duration and number of stopovers in black-bellied plovers, and these metrics explained substantial variation in reproductive success, while breeding season weather did not. In chapter 2, we found that in two study areas with contrasting habitat compositions, landcover type, time of day, and tide all explained substantial variation in energy expenditure (i.e., activity) in American avocets, but that relationships were different between the two sites. In chapter 3, we showed that shorebirds with different migration distances varied in both their migration strategies and in their plasticity in strategy. In chapter 4, we found that tracking devices performed well enough to meet most research objectives in standardized tests, however we caution that device performance is likely reduced when deployed on wild birds. We split chapter 5 in two parts: (a) we present current literature and techniques for studying animal social structure and demography, and (b) we developed a simulation study that evaluated performance of a model linking social network analysis and Cormack-Jolly-Seber survival models and found that models performed with minimal bias and good precision, but precision was influenced by data resolution.
Dissecting the genetic basis of carbohydrate partitioning in maize and sugarcane
Authors:   , Dhungana Singha Raj
Published: September 2022

[EMBARGOED UNTIL 6/1/2023] Carbohydrate partitioning, the process by which carbohydrates synthesized in the photosynthetic source tissues (mature leaves) are mobilized to non-photosynthetic (sink) tissues, such as roots, seeds, and developing organs is crucial for plant growth, development, and yield. Various physiological, biochemical, and anatomical studies have addressed this process, but the genetic control of carbohydrate partitioning is still not well understood. The main purpose of this dissertation is to elucidate aspects of the genetic control of carbohydrate partitioning in maize and sugarcane. Chapter 1 summarizes our current knowledge of phloem loading in grasses, the principal families of sugar transporters involved in sucrose transport, and novel mechanisms by which the activities of these sugar transporters are modulated. It also elaborates some of the recent discoveries in some eudicot species. Chapter 2 describes the genome of the wild ancestor of sugarcane (Saccharum spontaneum) and presents some ideas about the genes that may regulate sugar storage in the modern sugarcane varieties. For this study, I annotated Sucrose Transporters (SUTs) and Tonoplast Sugar Transporters (TSTs) in the S. spontaneum genome. Similarly, Chapter 3 describes the sugar transporter families; SUTs and TSTs in low (Saccharum spontaneum) and high sugar accumulating (Saccharum officinarum) sugarcane species and takes a comparative genomics approach to understand the ability of modern sugarcane cultivars to store huge amounts of sugars in their stem. Chapter 4 describes the characterization and cloning of maize carbohydrate partitioning defective13 (cpd13) and carbohydrate partitioning defective35 (cpd35) mutants, whereas Chapter 5 describes the characterization and progress towards cloning of carbohydrate partitioning defective60 (cpd60) and carbohydrate partitioning defective87 (cpd87) mutants. All of these mutants are recessive and contribute to carbohydrate hyperaccumulation in the mature leaves of the mutant due to reduced sucrose export. The cpd13 and cpd35 mutations affect a Dna-J-thioredoxin-like protein, which is hypothesized to be involved in processing of proteins and have chaperone-like activities. The cpd60 and cpd87 mutations result in ectopic lignin in the phloem of mature leaves, but the mechanism and the gene involved remain to be identified. Chapter 6 summarizes the discoveries made in the previous chapters and presents future research directions. Appendix A is a research article that I collaborated on and contributed to the measurement of non-structural carbohydrates in very oil yellow1 (vey1) leaves introgressed to B73 and Mo17 inbred lines. Collectively, the research presented here has enhanced our understanding of the genetic control of carbohydrate partitioning in maize and sugarcane. These studies establish the foundations for future experiments to determine the genetic architecture controlling carbohydrate partitioning in plants.
Novel insights into strand cleavage at an abasic site in DNA
Authors:   , Haldar Tuhin Subhra
Published: September 2022

[EMBARGOED UNTIL 6/1/2023] Loss of a nucleobases from the deoxyribose backbone of DNA generates Abasic sites in DNA. Abasic sites are the most common unavoidable DNA damage lesion. It is important to understand the properties of Abasic site. The acidic nature of the [alpha]-protons of the ring-opened abasic aldehyde residue facilitates the [beta]-elimination of the 3'-phosphoryl group. This reaction is expected to generate a DNA strand break with a phosphoryl group on the 5'-terminus and a trans-[alpha],[beta]-unsaturated aldehyde residue on the 3'-terminus; however, a handful of studies have identified noncanonical sugar remnants on the 3'-terminus, suggesting that the products arising from strand cleavage at apurinic/apyrimidinic sites in DNA may be more complex than commonly thought. The strand cleavage in DNA at an abasic site induced by the treatment of heat, NaOH, piperidine, spermine, and the base excision repair glycosylases Fpg and Endo III has been characterized. DNA oligomer generated noncanonical sugar remnants including cis-[alpha],[beta]-unsaturated aldehyde, 2-deoxyribose, and 3-thio-2,3-dideoxyribose products on the 3'-terminus of the strand break. Cells contain millimolar concentration of spermine, which can induce strand cleavage at an abasic site in DNA generate very reactive [alpha],[beta]-unsaturated aldehyde iminium ion. Deoxyguanosine Triphosphate (dGTP) can react with the [alpha],[beta]-unsaturated aldehyde iminium ion of the on the 3'-end of the Ap-derive strand cleavage and generates a previously uncharacterized 3'dGTP-ddR adduct.
Reflections of residents in a rural Midwestern community on the impacts of a successful university football program, their tendency to bask in reflected glory, and their social identity
Authors:   , Hornickel Mark D.
Published: September 2022

[EMBARGOED UNTIL 6/1/2023] Intercollegiate athletics are embedded in the fabric of American culture and provide a source of unity and pride for the students, universities, and communities they represent (Beyer and Hannah, 2000; Duderstadt, 2003; Gumprecht, 2003; Vanover and DeBowes, 2013). This qualitative study sought to understand, within the conceptual framework of basking in reflected glory (BIRG) established by Cialdini et al. (1976) and social identity theory (SIT) established by Tajfel and Turner (1979), the perceptions and lived experiences of residents in a rural Midwestern community and the impacts of a successful university football program that inhabits their community. While the study sought to contribute to the existing literature connected to BIRG and SIT, it also fills a gap in the scholarly research where qualitative methods studying an NCAA Division II environment is scarce. Supported by the previously published literature, themes emerged that showed residents' BIRG tendencies as well as evidence of team identification and social anchors among the residents who associate with the football program. Recommendations for practitioners and scholars include using the findings to better understand the value of intercollegiate athletics in enhancing the identities of broader campus communities and studying an urban setting where a successful NCAA Division II athletics program exists.
Parsimonious item response theory modeling with different link functions
Authors:   , Shim Hyejin
Published: September 2022

[EMBARGOED UNTIL 6/1/2023] Traditional item response theory (IRT) models assume a symmetric error distribution and rely on symmetric (logit or probit) link functions to model the response probabilities. However, this assumption does not always hold in item response data. To explore the possible benefits of alternate link functions, I developed and investigated a set of one-parameter IRT models for unidimensional tests with dichotomous items by specifying the complementary log-log (CLL), negative log-log model (NLL), and cauchit links. In a series of simulations studies, I demonstrated that these parametrically parsimonious alternate-link IRT models are comparable to traditional IRT models with regard to (1) data distribution shape, (b) inflection point shift, (c) structural similarities, and (d) response behaviors. Importantly, these four properties provide a rationale for how certain parametrically simple alternate-link models can outperform more parametrically complex traditional IRT models. Specifically, I demonstrate that the CLL model accounts for the effect of guessing because it has an item characteristic curve with a higher inflection point than that of the traditional Rasch or two-parameter logistic (2PL) models. Similarly, the NLL model addresses the effects of slipping via an inflection point that is lower than in the Rasch or 2PL models. Importantly, unlike traditional IRT models that focus on guessing and slipping as response behaviors associated with the extreme levels of the latent trait, I show that the CLL and NLL models assume such behaviors affect responses across the entire range of the trait. I also present the cauchit model, which treats both guessing and slipping effects as outliers. The simulation results reveal that these one-parameter alternate-IRT models are robust to small sample sizes (e.g., N = 100), and facilitate item-weighted scoring. I then provide further evidence for these claims by applying the CLL, NLL, and cauchit models to empirical data. Finally, I propose some extensions of alternate-link IRT modeling beyond the particular (unidimensional dichotomous) context that formed the basis of my simulations and empirical analysis. I conclude by discussing the implications of this work for applied measurement and psychometric research.
The LASSI as a measure of doctoral of physical therapy students study skills and its relationship to PEAT and NPTE
Authors:   , Stephens Kelly
Published: September 2022

[EMBARGOED UNTIL 6/1/2023] Physical therapy students, like most students frequently use poor study strategies that do little to promote long term retention. This undermines the ability to pass a comprehensive entry level licensure exam. This research correlated the Learning and Study Skills inventory (LASSI) with retrospective GRE scores and prospective performance on the National Physical Therapy Examination. The sample was physical therapy students from the University of Missouri including five cohorts of students (N= 456). Measures included the LASSI, GRE, Practice Exam and Assessment Tool (PEAT), and National Physical Therapy Examination (NPTE). The PEAT and NPTE represent the board exam performance. A factor analysis was performed to determine the most appropriate factor structure for this sample. A six-factor structure was the most appropriate but complicated by numerous cross loadings of items. Analyses used the 3rd addition of the LASSI and the total score. Students did not significantly increase in LASSI scores as they progressed through the program, suggesting that they did not improve their use of study strategies. The GRE did not predict LASSI scores for this sample. The LASSI predicted student performance on the PEAT and for the NPTE, but prediction was not statistically significant for the NPTE.
Data combining using mixtures of g-priors with application on county-level female breast cancer prevalence
Authors:   , Wang Qiao
Published: September 2022

[EMBARGOED UNTIL 6/1/2023] As more and more data are available, data synthesis has become an indispensable task for researchers. From a Bayesian perspective, this dissertation includes three related projects and aims at quantifying the benefits of combining data under various scenarios in terms of the theoretical properties including biases, frequentist variances, and mean squared errors. In the first project, data combining of linear models with the classical mixtures of g-priors is investigated. We calculate and compare the posterior estimates and the frequentist properties of the Bayesian estimator from the model with individual and combined data. To resolve the newly identified conditional Lindley paradox and relax constraints on design matrix, data combining with independent mixtures of g-prior is explored, where a different scale is used for each group of coefficients. We not only perform a posterior variance analysis, but also offer a conditional asymptotic analysis of the Bayesian estimators. We also apply the corresponding results in the comparison of models for individual and combined data. Furthermore, to reflect how the use of sample size impact the estimates in a data combining context, we compare the Zellner-Siow prior to its adjustment with the effective sample size. At last, an application on data combining of the 2016 county-level female breast cancer prevalence is presented using data from the Missouri Cancer Registry and Research Center, and the Missouri County-level Study. To provide a broader scope of the data combining framework, we study the linear mixed model and generalized linear mixed model with a conditional autoregressive prior serving as random effects.
Fatigue-recovery simulation model to analyze the impact of nursing activities on fatigue level in an intensive care unit
Authors:   , de Oliveira Vargas Vitor
Published: September 2022

[EMBARGOED UNTIL 6/1/2023] Although nursing is physically and mentally strenuous, not many studies have been done yet to find the impact of the key groups of tasks on nurses' average fatigue level and workflow. So, this study aims to understand the relationships among the key activities that impact the nurses' average fatigue level in an Intensive Care Unit (ICU). Nurses' time-study and real-time location data have been used to develop a simulation model in two different periods: February to March 2020 and July 2020. Two Hierarchical Task Analysis charts were generated from the collected data, one for each period, and used as the foundation for the fatigue-recovery simulation model. Both simulation models have been statistically tested and validated by comparing the time study observation data. Different scenarios of all nursing activities' frequencies (number of conducted tasks during a shift) and task sequences (number of times tasks are conducted continuously prior to a break) were simulated as independent variables. The dependent variable is their impacts on the nurses' predicted average fatigue levels during a shift. The main contribution of this work is that the model could provide a new way to estimate the nurses' fatigue levels in different workload conditions and to establish specific nursepatient ratios dynamically to improve patient care in a medical ICU. In this study, it was found that the major drivers for nurses' fatigue in an ICU shift is the number of times nurses conduct tasks in sequence without a break (number of task sequences), followed by the number of patient care or procedures, and peer support activities conducted in shift. However, the limitations in this study are the lack of the ratio number of nurses/number of patients during the shifts, the number of patients assigned to the assessed nurses, and regarding to the fatigue and recovery indexes. In this study, it is assumed three levels for the indexes, low, medium, and high, depending on the nature of the activity. It is recommended that, for the sake of more accurate results, in future studies, fatigue is monitored by a real-time method, in that way, there will be an estimated fatigue and/or recovery index for every single nurse task.
Discovery, design, and optimization of implantable/wearable, wireless biosensors
Authors:   , Heck Ian
Published: September 2022

[EMBARGOED UNTIL 6/1/2023] In the world of wireless technology, communication, power supply, and response time of the sensors are the focal points of device design. Bluetooth and Near-Field-Communication (NFC) are two excellent methods of communication ideal for short range wireless technology. Battery technology and wireless power transfer free devices from immobilizing power cords. Finally, optimizing real time detection and data delivery offers great advantages to the user when it comes to monitoring the targets. The goal of this work is to explore these focal points and find synergy between various methods and components to create novel, wearable, wireless biosensors. Because there is a countless amount of design combinations, these devices will utilize a combination of dependable and innovative technology, and certain components will be characterized and tested to reduce the subjectivity of their inclusion. From these tests, two different sensors passed preliminary tests that confidently suggest that the devices can operate in their intended environments. The current challenges posed by wireless biosensors can be seen as opportunities for improvement. In this document, we will explore the design process and operation of two different biosensors. The first biosensor that will be discussed, is a wireless, battery-less, implantable biosensor for optogenetic and pharmacological stimulation. For this work, the focus was on improving the sensor introduced in, Battery-free, lightweight, injectable microsystem for in vivo wireless pharmacology and optogenetics. Here, the focus lay on characterizing and potentially improving wireless power harvesting as well as novel programming to operate NFCbased devices. The second biosensor is a wireless, non-invasive pressure sensor intended to aid in diabetic foot ulcer healing. The focus of this work will lay on characterizing the pressure sensor and ultimately designing a device intended for clinical use. Both projects will have different testing criteria as to efficiently administer applicable tests and avoid redundant data that may not be pertinent to the project.
Gia Dinh for orchestra
Authors:   , Huynh Oswald
Published: September 2022

[EMBARGOED UNTIL 6/1/2023] Gia Dinh, meaning "family" in Vietnamese, is an exploration of intergenerational trauma, cultural inheritance, and what is lost between eras. Specifically, I am focusing on the greater Vietnamese diaspora and the Vietnamese boat people, who traveled across the ocean in makeshift boats in search of a future for their families. Many of my own family members were a part of this generation, and only within recent years have they chosen to share their stories with me. Each movement acts as a musical portrait of the various aspects and roots of intergenerational trauma and is titled with a Vietnamese proverb that describes the value of family and the perceived relationship between parent and child in Vietnamese culture. The opening movement, "Cha nao con nay," (Like father, like child) observes heritage, tradition, and culture as trauma. Conflicting generational values often create rifts between parent and child, particularly in Western countries. What should we pass down and teach? And at what cost? Borrowing thematic material from the Vietnamese folk song Ly Keo Chai, I present fragments of the song without ever presenting the melody in its entirety. These musical splinters are introduced clearly, but quickly disintegrate into the orchestral texture. The second movement,"Khong co gi bang com voi ca, khong co gi bang ma voi con," (There is nothing like rice with fish, there is nothing like mother with child) considers colonization and war as a source of trauma. Vietnam was colonized by the French in the mid-1800s, which played a large part in the spread of Catholicism among Vietnamese people. Shortly after Vietnam gained independence from France, the Vietnam War broke out, which ultimately led to the mass exodus from the country. A unique aspect of Vietnamese Catholic practice is the tradition of doc kinh, in which all prayers and responses are sung or chanted. I directly quote Kinh Thu Nhan (Penitential Act), which is preceded by a fragmented theme that slowly builds into the chant. The final movement, "Blood is thicker than water," (Mot giot mau dao hon ao nuoc la) examines migration, displacement, and assimilation as forms of trauma. In addition to what is passed on to the next generation, this movement also explores what is lost. Language, culture, and history can all be lost within a single generation as a result of displacement. This is represented musically by two extremely contrasting themes: a slow, lyrical melody inspired by Vietnamese folk melodies and a fractured, unrelenting section that cycles through the entire orchestra. I bounce between the two themes until the music melts into a coda that recalls the first movement.
Balanced entertainment: motivations behind watching cable news
Authors:   , Senk Aaron
Published: September 2022

[EMBARGOED UNTIL 6/1/2023] Cable news networks have a peculiar dynamic with their audiences compared to other television news mediums, as their privatized, highly competitive nature means they are especially dependent on attracting audiences and catering to viewer whims to maintain ratings. The nature of this dynamic has made it fertile ground for studies that examine it through a Uses and Gratifications Theory lens. Prior scholarly perspectives have focused largely on the partisan, ideological ways that cable news networks have catered to audiences, such as by decrying bias in competing networks or making vocal, performative gestures of their professed ideology. The Fox News Network is the most visible representation of this pattern of behavior, having over the decades cultivated a loyal, predominantly conservative audience, and a sizable amount of research on cable news networks has focused on Fox News and its audiences. This study sought to examine both Fox News and other cable news networks using Uses and Gratifications Theory, surveying cable news network audiences to get a sense of what uses and gratifications they tended to value and what areas they felt both their network of choice and other networks could improve in, so as to get a sense of what non-partisan factors may be serving as potential uses and gratifications for American cable news network viewers. The results of this study were mixed, and overall seemed to suggest that the independent variable that was aspects of one's personal identity and background such as age and political self-identity had a stronger influence on the dependent variable that was what uses and gratifications one prioritized instead of cable news network affiliation, which is true to the spirit of uses and gratifications theory.
Coprolites of the late eocene using virtual paleontology from the Pipestone Springs Main Pocket, Montana
Authors:   , Webb Jeremy Louis
Published: September 2022

[EMBARGOED UNTIL 6/1/2023]The study of coprolites and their internal constituents has previously employed a predominantly destructive means of extraction, resulting in the partial or complete loss of the specimen. Recently, however, there have been several studies adopting a more modern approach to data collection and analysis, incorporating three-dimensional imaging techniques such as x-ray tomographic microscopy ([mu]CT) and synchrotron microtomography. These non-destructive methods allow us to virtually extract qualitative information on the identity, structure, orientation, and size of inclusions, as well as important quantitative information with respect to the relative proportions of inclusions to matrix. Herein, [mu] CT was used to study bone, and other miscellaneous inclusions, in two size classes of coprolites from the Eocene Pipestone Springs Main Pocket (PSMP) assemblage (Renova Formation), Montana. Segmentation of [mu] CT-scans has enabled documentation of the degree of skeletal fragmentation and proportion of bone material to the phosphatic matrix which provides novel insights into the feeding behavior of the producer and taphonomy of constituents. Among the features identified in the [mu] CT data were skeletal fragments, including those showing evidence of bone-crushing; delicate molds of hair; lithic fragments encrusted on the coprolite surface; and lastly several pores and cracks throughout the coprolites' structure. A benefit of this technique is the ability to extract quantitative data on bone volumes and diameters for statistical comparison between the two different size classes of coprolite. In combination with volume renders of the segmented material, we also adopt more traditional methods such as thin-section petrography and scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS) to characterize the compositional and taphonomic attributes of the samples. We emphasize that traditional methods are not obsolete, as they provide data that cannot be obtained using digital methods. X-ray microscopy compliments traditional methods insofar that areas of interest can be identified prior to destructive sampling. Overall, this combined approach has provided a means to observe and statistically test differences in the coprolite gross morphology and their inclusions across the two size classes thereby offering valuable insights into the broader paleoecology of the PSMP coprolite producers.
The development of the Heterodimeric enhanced Yeast-One Hybrid (HD-eY1H) assay
Authors:   , Zachary Christopher Nathan
Published: September 2022

[EMBARGOED UNTIL 6/1/2023] Life can be summarized as a continuous struggle to maintain homeostasis - or balance - despite dynamic changes in environmental conditions. Changes in gene expression is one of the many ways organisms can interact and respond to their environment to adapt and preserve homeostasis. The central dogma of biology tells us about the flow of genetic information from DNA to RNA and then from RNA to proteins, who ultimately execute metabolic processes. Understanding the mechanisms that dictate gene expression offers the possibility of untangling the complex regulatory networks that have evolved over time. And these regulatory networks cover all aspects of survival for an organism and are what allow life to fleetingly maintain homeostasis. This thesis summarizes the development of the Heterodimeric eYeast-One Hybrid (HD-eY1H) assay, which was developed to identify novel protein-protein-DNA interactions. As a proof of concept, we used HD-eY1H to explore the iron homeostatic network in the reference plant Arabidopsis thaliana.

Can Maternal Colostrum Be Replaced by Commercial Products for Feeding Newborn Calves?
Authors: Galvao Klibs N.
Published: September 2022

Colostrum management and feeding are critical for calf health, calves’ future productive life, and farm profitability. Current recommendations state that a calf needs to ingest at least 150–200 g of immunoglobulin G within two hours of birth, but when colostrum quality is poor or unavailable, colostrum replacer may be a suitable alternative. This 3-page fact sheet presents the results of a recent publication that evaluated the effects of feeding maternal colostrum, one dose of plasma-derived colostrum replacer, or one dose of colostrum-derived colostrum replacer on serum total protein, immunoglobulin G concentration, calf morbidity, calf mortality, and weight gain from birth to weaning. Written by Klibs N. Galvao and published by the UF Department of Veterinary Medicine-Large Animal Clinical Sciences, May 2014.
