Harnessing Heterogeneity in Human Gut Microbiome Data

Creator:: Tataru, Christine
Abstract:: The focus of this thesis is to design, characterize, and apply novel computational methods and molecular systems to interrogate heterogeneous human gut microbiome-related phenomena. In Chapter 2, I design, implement, and characterize a method for embedding co-occurrence patterns derived from massive 16s amplicon datasets. I use this method to 1....

Comparative Metagenomic Investigations Link the Functional Capacity of the Gut Microbiome to Vertebrate Physiology

Creator:: Armour, Courtney R.
Abstract:: Microscopic organisms inhabit virtually every niche on this planet, where they perform functions vital to all life on earth. Accordingly, humans host a complex community of microorganisms (i.e. the gut microbiome) that inhabit the gastrointestinal tract and modulate host physiology. Insight into the specific mechanisms through which gut microbes influence...

Toward making the invisible visible : studying science teaching self-efficacy beliefs

Creator:: Perkins, Catherine J.
Abstract:: This dissertation consists of two articles to be submitted for publication. The first, a literature review, makes visible common influences on science teaching self-efficacy beliefs and also points to potentially invisible validation concerns regarding the instrument used. The second investigates the participants' invisible science teaching self-efficacy beliefs and, through the...

Ecophylogenetic Characterization of the Gut Microbiome of At-risk Companion and Food Animals

Creator:: Kirchoff, Nicole S.
Abstract:: Agricultural and companion animals are integral to our way of life as they provide us with nourishment, financial resources, transportation, and companionship. However, pets, managed animals in the agricultural industry, as well as wild populations of food animals are all subject to health and mortality risks. The gut microbiome is...

Temperature and water potential effects on physiological functions of sudangrass (Sorghum vulgare var. Piper)

Creator:: Young, Richard Su-Shung
Abstract:: Temperature and water potential effects on the growth, transpiration, total nonstructural carbohydrate (TNC) content, and nutrient uptake of sudangrass (Sorghum vulgare var. piper) were investigated in laboratory experiments. The effect of nitrogen supply on the growth and nutrient uptake at constant soil water potential was also investigated in this study....

From Microbes to Megafauna: The Ecology of Gut Microbiomes in Wild Herbivores

Creator:: Couch, Claire E.
Abstract:: All mammals host communities of commensal microbes in and on their bodies. Recent technological advances, combined with experimental studies in laboratory animals, are beginning to reveal the ubiquitous links between the gut microbiome and host disease, metabolism, immunity, and numerous other host functions. A new challenge of microbiome research is...

The influence of participating in a mandatory mixed-format student success seminar on persistence in an urban community college

Creator:: Mendoza, James A.
Abstract:: Over the past twenty years, the national three-year graduation rate for community college students has ranged from 44% to roughly 31% in 2013 (NCES, 2013). As a way to address such low graduation rates, colleges have implemented a myriad of services and programs (i.e., tutoring, mentoring, etc.). Another intervention is...

Validation of an instrument for mathematics enhancement teaching efficacy of Pacific Northwest agricultural educators

Creator:: Jansen, Daniel J.
Abstract:: Teacher efficacy continues to be an important area of study in educational research. This study tested an instrument designed to assess the perceived efficacy of agricultural education teachers when engaged in lessons involving mathematics instruction. The study population of Oregon and Washington agricultural educators utilized in the validation of the...

Lesbian leaders in action : influencing and transforming community college culture

Creator:: Kenney, Rebecca J.
Abstract:: The purpose of this study is to explore through their own stories and journeys (storjourns), how lesbian leaders influence and transform dominant community college culture. Five lesbian leaders participated who held the position of Director, Associate Dean, Dean, Executive Vice President, and President/Executive Dean. This microethnographical inquiry divulges and makes...

The Roles of Dietary Nitrate in Bone and the Gut in an Ovarian Hormone-deficient Rodent Model

Creator:: Conley, Melissa N.
Abstract:: Osteoporosis is a common metabolic bone disease, affecting a third of women and a fifth of men over age 65. In the US, annual health care costs associated with osteoporosis are estimated to be over $20 billion. Osteoporosis is associated with increased fracture risk, which has been demonstrated to predict...
