Evolution And Niche Specialization Of Microbial Taxa In Vaginal Infection And Pregnancy, Abigail L. Glascock

Theses and Dissertations

The vaginal microbiome plays an important role in reproductive health and pregnancy. It has coevolved with humans and has direct effects on reproductive success, rendering selective pressure more pronounced at this site. Herein, we probe coevolution of the vaginal microbiome using a systems-level approach. In Chapter 2, we examine the evolutionary trajectory of two vaginal Veillonellaceae phylotypes evolved from an ancestral gastrointestinal lineage to inhabit the vaginal niche. We present evidence of their divergence and subniche specification and describe their differential associations with vaginal infection and pregnancy. In Chapter 3, we identify ten bacterial taxa, predicted to contribute to the …

Small Town Capital In Community, Christin Hardy

Theses and Dissertations

Rural towns often do not see community developments geared towards creating public spaces for multi-cultural experiences, the arts and recreation. Instead small towns are more exposed to commercial properties coming in and out the area. Introducing public spaces that offer various community activities and events will benefit people’s human and social capital. Human capital meaning skills and knowledge. Social capital meaning advantages and skills that come from interpersonal engagements (Anderson, 2004). Community centers designed for the unique needs of small towns can house programming to introduce new and rewarding opportunities for community engagement and personal development. Existing buildings within the …

Nam June Paik As A Pioneer Of Interactive Art, Byeongwon Ha

Theses and Dissertations

Nam June Paik (1932-2006) is well known as the father of video art. However, this study demonstrates the importance of his earlier interactive art (1961-63), which historically has been overshadowed by his video art. At the climax of his career in interactive art, Paik introduced his two-way art to the public at his first solo exhibition in Wuppertal, West Germany, in 1963. Interactive art itself has been a peripheral area in the history of art, and it has plural pioneers across disciplinary boundaries. Among the several origins of interactive art, Nam June Paik utilized music as a fundamental approach to …

The Mall: A World-Building Speculation On The Future Of Privacy, Hazem Asif

Theses and Dissertations

This thesis is a science fiction exploration of a future dystopian world where privacy becomes a dominant currency that is distributed according to social class and ranking mechanisms. It utilizes speculative world-building to study the unanticipated implications of technology on personal privacy, surveillance and social inequality on future societies. The project introduces The Mall, as a highly efficient and hyper-connected world, but also exposes its downfall as a society with heightened cultural and socio-political disparities. Inspired by past civilizations, the development of the modern nation-state as well as contemporary society, the design adapts, appropriates and reformulates existing cultures into new …

Redox Reactions At Oil-Water Interface By Particle Collision Electroanalysis, Dilip K. Paul

Theses and Dissertations

Particle Collision Electrochemistry (PCE) has gained considerable attention in heterogeneous catalysis, petroleum chemistry and pharmaceutical fields. The PCE refers to a phenomenon in which a particle strikes on an inert electrode surface as a consequence of its Brownian motion and produces a spike of current for the direct oxidation/reduction of the individual particle. This method allows us characterization of individual particles and in-situ study of electrochemical reactions coupled to the particle.

Herein, emulsion droplets were studied by PCE where toluene droplets contained hydrophobic tetrachloro-1,4-benzoquinone (Q). This was investigated as a model system to study the molecular effects that arise due …

Ultrasound—Re:Viewing Bodies, Minjee Jeon

Theses and Dissertations

A medical evaluation of physical impairment imposes the additional burden of “labeling” the patient with the condition. The binary nature of the normal versus abnormal label emphasizes difference and can lead to trauma. Understanding differences, however, can lead to the generation of new forms and thus, more sensitive differentiation and representation. Tension is created by exploring different bodily forms—a dialectic between form and essence. I am designing a space that visualizes and illuminates difference as a source of trauma and amplifying the tension by comparing figures that represent varying degrees of normalcy. This forms a critique of idealized form and …

Investigating Smoke Exposure And Chronic Obstructive Pulmonary Disease (Copd) With A Calibrated Agent Based Model (Abm) Of In Vitro Fibroblast Wound Healing., James A. Ratti

Theses and Dissertations

COPD is characterized by tissue inflammation and impaired remodeling that suggests fibroblast maintenance of structural homeostasis is dysregulated. Thus, we performed in vitro wound healing experiments on normal and diseased human lung fibroblasts and developed an ABM of fibroblasts closing a scratched monolayer using NetLogo to evaluate differences due to COPD or cigarette smoke condensate exposure. This ABM consists of a rule-set governing the healing response, accounting for cell migration, proliferation, death, activation and senescence rates; along with the effects of heterogeneous activation, phenotypic changes, serum deprivation and exposure to cigarette smoke condensate or bFGF. Simulations were performed to calibrate …

Consuming Digital Debris In The Plasticene, Stephen R. Parks

Theses and Dissertations

Claims of customization and control by socio-technical industries are altering the role of consumer and producer. These narratives are often misleading attempts to engage consumers with new forms of technology. By addressing capitalist intent, material, and the reproduction limits of 3-D printed objects’, I observe the aspirational promise of becoming a producer of my own belongings through new networks of production. I am interested in gaining a better understanding of the data consumed that perpetuates hyper-consumptive tendencies for new technological apparatuses. My role as a designer focuses on the resolution of not only the surface of the object through 3-D …

Quotations Like The Sharpest Claws, Johanna Robinson

Theses and Dissertations

Quotations like the Sharpest Claws describes a multimedia installation composed of paintings and sound that explores the theory of cognitive dissonance, a controversial psychological model that attempts to explain how we deal with inconsistency in incompatible beliefs. Imagination is given primacy as a source for truth-seeking and world-building. The uncanny and surreal are used as entry points into this topic.

The title is derived from a description of Eileen Myles’ poetry I once read in an anonymous review. Their writing was described as beyond poetry in a way that it could only be described as such when surrounded by “quotations …

Nitrogen Rich Porous Organic Frameworks: Proton Conduction Behavior Of 3d Benzimidazole And Azo-Linked Polymers, Michael J. Anhorn

Theses and Dissertations

Nitrogen-rich porous organic frameworks show great promise for use as acid-doped proton conducting membranes, due to their high porosity, excellent chemical and thermal stability, ease of synthesis, and high nitrogen content. Aided by very high surface area and pore volume, the material has the ability to adsorb high amounts of H₃PO₄ into its network, which creates a proton rich environment, capable of facile proton conduction. The morphology and chemical environment, doping behavior, and proton conduction of these materials were investigated. With such high acid-doping, ex-situ studies revealed that under anhydrous conditions, PA@BILP-16 (AC) produced a proton conductivity …

Advances In Dual-Energy Computed Tomography Imaging Of Radiological Properties, Dong Han

Theses and Dissertations

Dual-energy computed tomography (DECT) has shown great potential in the reduction of uncertainties of proton ranges and low energy photon cross section estimation used in radiation therapy planning. The work presented herein investigated three contributions for advancing DECT applications. 1) A linear and separable two-parameter DECT, the basis vector model (BVM) was used to estimate proton stopping power. Compared to other nonlinear two-parameter models in the literature, the BVM model shows a comparable accuracy achieved for typical human tissues. This model outperforms other nonlinear models in estimations of linear attenuation coefficients. This is the first study to clearly illustrate the …

The Player’S Journey: Ludology And Narratology In Modern Gaming, Angelica Fuchs

Theses and Dissertations

This thesis examines the evolution of gaming criticism (specifically ludology and narratology) and games as a medium of expression through the use of case studies. These case studies look at some of the core aspects of four major titles (The Last of Us, Horizon Zero Dawn, various BioWare games and Journey) and survey how these games work to effectively employ a narrative while maintaining an immersive, intuitive system for the player to interact with. Through these titles, the thesis suggests that in order to gain a full scope of a game’s intentions, studies should analyze more than …

Laminated Paint, Travis R. Austin

Theses and Dissertations

Though we may not perceive it, we are surrounded by material-in-flux. Inert materials degrade and the events that comprise our natural and social environments causally thread into a duration that unifies us in our incomprehension. Sounds reveal ever-present vibrations of the landscape: expressions of the flexuous ground on which we stand.

Escapism: Indulging In Daydreams, Tanruk Pairoj-Boriboon

Theses and Dissertations

A fantasy world, that exists only in our minds, provides us a place where we can mentally escape from everyday reality. Escapism, such as indulging in daydreams, allows us to experience comfort and makes us feel safe, eliminating feelings of insecurity and vulnerability.

This study aims to use playfulness and reverie as a tool to access and confront mental discomforts. Transforming disturbing situations into an experience of reverie; a correction of unsatisfying reality, by converting a solid component of the real world into a desirable infinite form will provide alternative viewpoints.

Throughout my work, this method has been employed to …

Psychick Order, Corissa Duffey

Theses and Dissertations

Preserving Psychick Order is an investigation into the subliminal, of a body processing trauma and transition. I explore how my mind and body filter memory, fear, and the impact of the past into the present. Since childhood, making dolls has been a way for me to express complex feelings, especially as they relate to dynamics between biological and found family. By tenderly modeling dolls after my own transforming physical features and mental processes, I make connections between the effects of my mind on my body and vice versa. I like to describe the resulting forms as queer monsters trying to …

Engineering Surface Properties To Modulate Inflammation And Stem Cell Recruitment Through Macrophage Activation, Kelly M. Hotchkiss

Theses and Dissertations

Biomaterials are becoming the most commonly used therapeutic method for treatment of lost or damaged tissue in the body. Metallic materials are chosen for high strength orthopaedic and dental applications. Titanium (Ti) implants are highly successful in young, healthy patients with the ability to fully integrate to surrounding tissue. However the main population requiring these corrective treatments will not be healthy or young, therefore further research into material modifications have been started to improve outcomes in compromised patients. The body’s immune system will generate a response to any implanted material, and control the final outcome. Among the first and most …

Understanding The Role Of Phosphoinositide 3-Kinase And Its Function As A Driving Force Behind The Er Stress Response In Fibrostenotic Crohn’S Disease-Affected Ileal Smooth Muscle Cells, Prashant Yadav

Theses and Dissertations

Crohn’s disease (CD) affects about 780,000 people in the United States alone, and it is estimated that 6-15 per 100,000 persons will receive a diagnosis of this disease each year. There currently is no cure for Crohn’s disease, and available medical therapies simply serve to alleviate the inflammation. This does not help treat fibrostenosis that Crohn’s disease patients may develop, which can only be treated surgically. Finding alternatives to treat CD requires an understanding of mechanisms at the biochemical level. In this thesis, we attempted to gain a better understanding of certain pathways found to be active in Crohn’s disease-affected …

Reliability And Validity Of The Humboldt Food Addiction Questionnaire, Sarah R. Taylor

Cal Poly Humboldt theses and projects

Current research shows that foods high in sugar, salt, and fat can illicit addictive responses (Pursey, Stanwell, Gearhardt, Collins, & Burrows, 2014). Although measures of overeating pathology exist, only a few are dedicated to food addiction. Two of these measures are the Yale Food Addiction Scale (YFAS; Gearhardt, Corbin, & Brownell, 2009b) and the Eating Behaviors Questionnaire (EBQ; Merlo, Klingman, Malasanos, & Silverstein, 2009). Given the shortage of food addiction measures, the Humboldt Food Addiction Questionnaire (HFAQ) was developed to supplement the need for additional tools. Recruited from both a university and online, 626 participants completed this study. Reliability of …
