Group B Streptococcus In The Urine In Nonpregnant Adults: Disease Or Distraction?, Nicole Mongilardi, Brigid M. Wilson, Sunah Song, Robin L.P. Jump, Federico Perez

Faculty Scholarship

In this large, retrospective cohort study, we used administrative data to evaluate nonpregnant adults with group B Streptococcus (GBS) bacteriuria. We found greater all-cause mortality in those with urinary tract infections compared to asymptomatic bacteriuria. Differences in patients' baseline characteristics and the 1-year mortality rate raise the possibility that provider practices contribute to differences observed.

Crossing The Threshold: Factors That Influence The Beliefs Of First Year Teachers Regarding Reform-Based Mathematics Instruction, Quinn H. Braden

Theses and Dissertations

Teacher preparation programs invest significant resources to influence the beliefs of preservice teachers, including clinical faculty who mentor preservice teachers during practicum experiences. Despite the work of university personnel to guide preservice teachers' beliefs, their influence wanes once preservice teachers cross the threshold into inservice teaching. New mentors, including mentor teachers, instructional coaches, and administrators take the place of university personnel. This quantitative study examined how the beliefs of 77 novice inservice teachers changed toward reform-based mathematics instruction during their first year of teaching. Of the 77 subjects, 50 were interns and 27 had completed student teaching. Near the end …

Field Based Study Of Gravel Liquefaction, Jashod Roy

Theses and Dissertations

Characterization and assessment of liquefaction potential of gravelly soil in a reliable cost-effective manner has always been a great challenge for the geotechnical engineers. The typical laboratory investigation techniques have proven to be ineffective for characterizing gravelly soil due to the cost and difficulty of extracting undisturbed sample from gravelly deposits. The traditional in-situ tests like SPT or CPT are not very suitable for gravelly soil because of interference with large size gravel particles which can artificially increase the penetration resistance. The Becker Penetration Test, well known for gravelly soil characterization, is cost-prohibitive for routine projects and is not available …

The Influence Of Land Coverage And Soil Chemical Factors On Soil Bacterial Community Diversity And Structure In Cedartown, Ga, Usa, Jake Smith

Master of Science in Integrative Biology Theses

Heavy metals pose serious threats to organisms due to their mobility and solubility in soil. Bacteria communities are vulnerable to heavy metal stress, but the response of different bacterial groups may vary depending on the level and type of heavy metal contamination. When subjected to heavy metal stress, many bacterial species or populations may become extirpated, while some may survive to form the foundations of a new microbial community. A study of the bacterial community at a lead (Pb) contaminated study site in Cedartown, GA, found that the microbiome in the Pb contaminated soil had significantly lower species richness. But …

Children’s Nutrition Research Center Staff Publications

Background: Glycine is a proteogenic amino acid that is required for numerous metabolic pathways, including purine, creatine, heme, and glutathione biosynthesis. Glycine formation from serine, catalyzed by serine hydroxy methyltransferase, is the major source of this amino acid in humans. Our previous studies in a mouse model have shown a crucial role for the 10-formyltetrahydrofolate dehydrogenase enzyme in serine-to-glycine conversion.

Objectives: We sought to determine the genomic influence on the serine-glycine ratio in 803 Hispanic children from 319 families of the Viva La Familia cohort.

Methods: We performed a genome-wide association analysis for plasma serine, glycine, and the serine-glycine ratio …

Abm Simulation Model Of A Pandemic For Optimizing Vaccination Strategy, Gibeom Park

Theses and Dissertations

This study presents a process-oriented hybrid model for individuals' immune responses and interactions involving vaccination to describe the trend of contagious disease and estimate the future societal cost. The model considers "recovery" as a non-absorbing state and incorporates various infection stage states including two symptomatic states. To model contagiousness to be consistent with the current pandemic and include that the spread of a disease depends on the mobility of people, we developed an Agent-Based Simulator that fitted to the particular model used in this study and can test various what-if scenarios. We improved the simulator considerably by appying data structures …

On Epidemiology As Racial-Capitalist (Re)Colonization And Epistemic Violence, Ryan J. Petteway

OHSU-PSU School of Public Health Faculty Publications and Presentations

This commentary reflects upon power-knowledge dynamics and matters of epistemic, procedural, and distributive justice that undergird epidemiological knowledge production related to racial health inequities in the U.S. Grounded in Foucault’s power-knowledge concepts—“objects”, “ritual”, and “the privileged”—and guided by Black feminist philosopher Kristie Dotson’s conceptualization of epistemic violence, it critiques the dominant positivist, reductionist, and extractivist paradigm of epidemiology, interrogating the settler-colonial and racial-capitalist nature of the knowledge production/curation enterprise. The commentary challenges epidemiology’s affinity for epistemological, procedural, and methodological norms that effectively silence/erase community knowledge(s) and nuance in favor of reductionist empirical representations/re-presentations produced by researchers who, often, have never …

Batterer Intervention Program Evaluation: A Portland, Oregon Program Case Study, Julie M. Conner

University Honors Theses

Batterer intervention programming (BIP) has shown up as a source of treatment for men who abuse women since the late nineteen-seventies and have since continued to expand. Research has been done to examine how effective these programs are in many different settings at reducing intimate partner violence, but little is known about programs specific to the state of Oregon. BIPs are used as an alternative to incarceration for individuals convicted of domestic violence: existing programs are based on the Duluth Model and Cognitive Behavioral Theory (CBT). Other modalities have utilized trauma-informed approaches, psychoeducation, holistic modeling, and risks, need, and responsivity …

My thesis investigates the performative response to gender-based violence in contemporary art in Mexico during the 1970’s and then again in the post-NAFTA era, with the aim of examining the use of the artists body, the voices of women as substitution for the body, and the bodies of others as means of creating a greater awareness to the feminicidal epidemic. Artists like Mónica Mayer and Lorena Wolffer use their body and the voices of woman, as opposed …

Exploring The Lncrnas Related To Skeletal Muscle Fiber Types And Meat Quality Traits In Pigs, Rongyang Li, Bojiang Li, Aiwen Jiang, Yan Cao, Liming Hou, Zengkai Zhang, Xiying Zhang, Honglin Liu, Kee Hong Kim, Wangjun Wu

Department of Food Science Faculty Publications

The alteration in skeletal muscle fiber is a critical factor affecting livestock meat quality traits and human metabolic diseases. Long non-coding RNAs (lncRNAs) are a diverse class of non-coding RNAs with a length of more than 200 nucleotides. However, the mechanisms underlying the regulation of lncRNAs in skeletal muscle fibers remain elusive. To understand the genetic basis of lncRNA-regulated skeletal muscle fiber development, we performed a transcriptome analysis to identify the key lncRNAs affecting skeletal muscle fiber and meat quality traits on a pig model. We generated the lncRNA expression profiles of fast-twitch Biceps femoris (Bf) and slow-twitch Soleus (Sol) …

Valuing Angling On Reservoirs Using Benefit Transfer, Richard T. Melstrom, Mark A. Kaemingk, Nicholas W. Cole, John C. Whitehead, Christopher J. Chizinski, Kevin L. Pope

Biology Faculty Publications

Economic assessments are rarely applied to inland recreational fisheries for management purposes, especially when compared to fish, habitat, and creel assessments, yet economic assessments can provide critical information for management decisions. We provide a brief overview of economic value, key terminology, and existing economic techniques to address these issues. Benefit transfer, a technique used to measure economic value when an original analysis is not practicable, is conducted by drawing on existing estimates of economic value in similar contexts. We describe an application of benefit transfer to measure the economic value of several recreational fisheries in Nebraska, USA. We examine two …

Understanding The Complexities Of Anemia In Chronic Inflammatory Diseases From Diagnosis To Treatment, Naomi Rae Flindt

Theses and Dissertations

Iron is an essential nutrient for energy and DNA replication. Its homeostasis is commonly perturbed by chronic inflammatory mechanisms. Chronic inflammation upregulates a cytokine, hepcidin, that degrades the iron export protein ferroportin. Without a way to export iron into the bloodstream iron availability in blood becomes depleted. Iron depletion in the blood stream hinders erythropoiesis and is termed anemia. Herein I investigate and inhibit the mechanism of hepcidin activation. Inhibition of hepcidin activation has released iron from tissues and alleviated anemic conditions in a cancer model. I have laid the foundation to investigate this pathway in a 3D spheroid model. …

We also include a case of a constitutional balanced t(9;22) carrier from our institution. Among the 16 balanced t(9;22) carriers in our review, 13 were maternal and 3 were paternal. Of the 15 unbalanced translocation cases identified, 13 were live births, one was a missed abortion, and one resulted in pregnancy termination. The spectrum of established syndromes reported among the live births was the following: trisomy 9p syndrome (6/13), dual trisomy 9p and DiGeorge syndrome …

Impacts Of Spatial Resolution And Viewing Angle On Remotely Sensed Estimates Of Spartina Alterniflora Aboveground Biomass, Avery Miller

Theses

Coastal salt marshes sequester large quantities of “blue carbon” in plant biomass and sediments, and provide numerous other valuable ecosystem functions and services. However, these ecosystems are increasingly threatened by external stressors, including rising sea levels and a changing climate, which have resulted in large losses of tidal marsh habitat. Measuring plant biomass is critical for understanding how carbon storage may be affected as stressors continue to cause marsh losses, and for improving conservation and management efforts. A number of studies have quantified aboveground biomass (AGB) in salt marshes using remote sensing techniques, and with the development of high resolution …

Coffit: An Interaction Design Project For Remote Employees To Enjoy Casual Talks And Interact With Each Other In A Virtual Environment, Yifei (Effie) Wang

Theses

The impact of the COVID-19 pandemic has changed a portion of people’s way of living and forced a radical shift in working habits. Due to restrictions of non-essential travel and the need for social distancing, many companies have adopted a work-from-home policy for their employees; with some even allowing it to be a permanent move. The policy creates a number of benefits such as increased productivity, reduced commuting time costs, attracting the best talent from any location, and more. And yet challenges have appeared. Long-term remote workers frequently experience feelings of loneliness and isolation, as well as a decline in …

Exoskeletal Predator Defenses Of Juvenile California Spiny Lobsters (Panulirus Interruptus) Are Affected By Fluctuating Ocean Acidification-Like Conditions, Kaitlyn B. Lowder, Maya S. Devries, Ruan Hattingh, James M.D. Day, Andreas J. Andersson, Phillip J. Zerofski, Jennifer R.A. Taylor

Faculty Research, Scholarly, and Creative Activity

Spiny lobsters rely on multiple biomineralized exoskeletal predator defenses that may be sensitive to ocean acidification (OA). Compromised mechanical integrity of these defensive structures may tilt predator-prey outcomes, leading to increased mortality in the lobsters’ environment. Here, we tested the effects of OA-like conditions on the mechanical integrity of selected exoskeletal defenses of juvenile California spiny lobster, Panulirus interruptus. Young spiny lobsters reside in kelp forests with dynamic carbonate chemistry due to local metabolism and photosynthesis as well as seasonal upwelling, yielding daily and seasonal fluctuations in pH. Lobsters were exposed to a series of stable and diurnally fluctuating reduced …

Estimating Age In Mule Deer: Accuracy And Influence On Reproduction, Morgan S. Hinton

Theses and Dissertations

Accurate estimates of parameters and demographic rates of wildlife populations are crucial to management and conservation. One parameter of interest is age because it influences multiple demographic rates and behaviors including reproduction, dispersal, migration, and disease transmission. There are a number of methods used to estimate ages of wildlife. One of the most common methods used for mammals is evaluation of patterns in dental eruption and tooth wear. In the first chapter, we evaluate the accuracy associated with estimates of age from dental eruption and patterns of tooth wear for mule deer (Odocoileus hemionus). In the second chapter, we use …

The study took place along five state routes in the Salt Lake City metropolitan area. Snowplows and intersections were equipped with the technology to communicate and process requests for signal preemption. Signal performance and vehicle performance analysis were performed to understand the impacts that snowplows requesting signal preemption had. Signal performance analysis was done to determine how snowplows with V2X systems using DSRC affected signals. Vehicle performance analysis was done to see if plowing and traffic …

Heavy Metal Distribution Across Three Georgia Estuaries Using Coastal Sharks As Sentinel Species, Allyson Stiles

Master of Science in Integrative Biology Theses

Estuaries are transitional environments that play key roles in coastal ecosystem functioning by providing essential habitats to ecologically important plant and animal species. Estuaries are exposed to a number of anthropogenic impacts, including heavy metal contamination from human activities. However, few studies have examined heavy metal distribution within Georgia’s estuaries and how intact salt marsh ecosystems could play a role in filtering and sequestering contaminants, such as Mercury (Hg). This thesis examined blood total mercury (THg) concentrations of four coastal shark species and concentrations of five heavy metals (Hg, As, Cr, Cu, and Pb) within the water and sediments of …
