Reducing Costs In Human Assisted Speech Transcription, Justin Rovin

Master's Theses

The only official documentation of the lawmaking process at the California Legislature is unedited video recordings of committee hearings, bill texts, votes and analyses. While the bills resulting from these hearings are clear, using video recordings to understand how a bill was created is far too laborious for the average citizen. To increase public transparency, a service that provides easier access to the bill creation process was needed. In response to this need, the Digital Democracy initiative was established at Cal Poly by the Honorable Sam Blakeslee, former California State Senator and founder of the Institute for Advanced Technology and …

Seasonal And Dilution Rate Impacts On Nannochloropsis Oceanica Productivity In Algae Raceway Ponds, Garrett Dameron Murawsky

Master's Theses

Biomass growth of the alga Nannochloropsis oceanica, cultivated outdoors in six pilot-scale raceway ponds, was monitored over the course of 1.5 years, at two different dilution regimes each season, to establish the effects on algal biomass productivity and concentration of dilution rate, pond water temperature, and solar radiation. The 4.5-m² ponds were located in a mild, mid-latitude, coastal region (central California). Experimental conditions were operated in duplicates or triplicates with a consistent artificial seawater medium, pond depth, pH range, paddle wheel mixing speed, and replete nutrient conditions for the duration of the study. Two cultivation regimes were used …

Fluid Flow Characterization In Rapid Prototyped Common Iliac Artery Aneurysm Molds, Daniel Cole Greinke

Master's Theses

The goal of this project was to determine whether i) fused deposition modeling could be employed to manufacture molds for vascular constructs, ii) whether vascular constructs could be created from these molds, and iii) to verify practical equivalence between observed fluid velocities. Dye tracking was to be employed to characterize fluid velocity profiles through the in vitro vascular constructs, including a half-vessel model and a full vessel model of an iliac artery aneurysm. A PDMS half-vessel construct was manufactured, and the movement of dye through the construct was tracked by a cellphone camera. Thresholds were applied to each video in …

Pink And Dude Chefs: Impact Of A Nutrition And Culinary Education Program With Middle School Students In An Afterschool Setting, Jessie R. Bierlich-Wesch

Master's Theses

The epidemic of adolescent obesity has become one of the greatest public health concerns in the United States. Approximately 20.5% of adolescents of both sexes aged 12-19 years are considered obese. Higher rates of obesity are evident in ethnic minority and lower income status children with the highest prevalence among Hispanic/Latino and Black populations. The causes for obesity are multifactorial in nature and highlight disparities nationwide. These factors include socioeconomic status, education, environment, availability and access to fresh fruits and vegetables, and behavior patterns. Successful intervention methods that have reduced the impact of adolescent obesity have incorporated nutrition knowledge and …

Design And Validation Of A Fall Detection Application For Ios, Connor Lewis Mosley

Master's Theses

Despite significant preventative efforts, falls continue to be a major source of morbidity and mortality among the elderly. Additionally, the fear of falling can be a major obstacle to independent living for otherwise self-sufficient individuals. This fear is significantly heightened in individuals who have sustained a fall and often results in self-imposed restrictions on mobility and exercise, causing weakening in these individuals and further exacerbating the danger. Much time has been spent developing alert systems in an attempt to mitigate these problems. Unfortunately these systems typically involve dedicated monitoring centers and therefore often come with substantial upfront and recurring costs. …

Deciphering The Outer Envelope Of Thermotoga Maritima, Chaman Ranjit

Master's Theses

Thermotoga maritima is the representative member of the order Thermotogales, which is comprised of extremely thermophilic anaerobic bacteria. All members of this order are characterized by the presence of a unique outer envelope, the toga. The outer envelope appears as polar cellular distensions that sometimes are as large as the cytoplasm. The outer envelope increases in size while the cytoplasm remains the same leading to an outer envelope distension. The outer envelope distension development and increase in its size most likely occurs for storage of nutrients. Initial observations suggest that cells create larger distensions at the poles as they enter …

Investigation Of A Ubiquitous Spore Surface Protein, Justyna Kordzikowska

Master's Theses

All bacterial spores are comprised of concentric shells. All spores are encased in a layer called the coat. Some spores have an additional layer outside of the coat called the exosporium. Presumably, this morphological variation is an adaptation to variation in the environments in which these species can be found. However, spores from species with and without exosporia can often be found in the same niche. We hypothesize, therefore, that spores with and without exosporia share a common surface protein. Bacillus anthracis possess a well characterized surface protein called BclA. A BclA homologue is also present on the surface of …

Lipoate Metabolism In Staphylococcus Aureus Pathogenesis, Maria Azul Zorzoli

Master's Theses

Lipoate is an essential cofactor of several proteins involved in cellular energy homeostasis and catabolism. Lipoate metabolism has been linked to pathogenesis in some microbial species, but its role in Staphylococcus aureus infections had not been explored. In this thesis, we tested the hypothesis that lipoate acquisition mechanisms promote S. aureus infectivity. We used a bacterial genetics approach to elucidate the biological function of the S. aureus genes involved in lipoate metabolism. Our findings allowed us to propose a model for lipoic acid de novo biosynthesis and salvage pathways in S. aureus. Moreover, we detail hitherto undescribed genetic arrangements of …

Popularity Prediction Of Reddit Texts, Tracy Rohlin

Master's Theses

Popularity prediction is a useful technique for marketers to anticipate the success of marketing campaigns, to build recommendation systems that suggest new products to consumers, and to develop targeted advertising. Researchers likewise use popularity prediction to measure how popularity changes within a community or within a given timespan. In this paper, I explore ways to predict popularity of posts in reddit.com, which is a blend of news aggregator and community forum. I frame popularity prediction as a text classification problem and attempt to solve it by first identifying topics in the text and then classifying whether the topics identified are …

Testing Camera Trap Density Estimates From The Spatial Capture Model And Calibrated Capture Rate Indices Against Kangaroo Rat (Dipodomys Spp.) Live Trapping Data, Timothy A. Walker

Master's Theses

Camera trapping studies often focus on estimating population density, which is critical for managing wild populations. Density estimators typically require unique markers such as stripe patterns to identify individuals but most animals do not have such markings. The spatial capture model (SC model; Chandler & Royle, 2013) estimates density without individual identification but lacks sufficient field testing. Here, both the SC model and calibrated capture rate indices were compared against ten sessions of live trapping data on kangaroo rats (Dipodomys spp). These camera and live trapping data were combined in a joint-likelihood model to further compare the two methods. From …

Deconstructing Exploitative Systems And Restoring A Balanced Biosphere: An Ecofeminist Posthumanist Reading Of Jane Smiley's A Thousand Acres And Barbara Kingsolver's Prodigal Summer, Aubrey A. Laughlin

Master's Theses

Although many scholarly articles have provided ecofeminist insights and

critiques of A Thousand Acres that connect the abuse of women to the abuse of the land, few have dealt specifically with the link between the treatment of women and the treatment of nonhuman animals. In the first chapter of this paper, I argue that associations between women and nonhuman animals in A Thousand Acres sustain the constructed reality of patriarchal communities. Similarly, Prodigal Summer’s narratives center around females and nonhuman animals, but also provide a broader focus that emphasizes the interconnectivity of the entire biotic pyramid and optimistically holds that …

Land-Use And Algal Species Influence Bacterial Community Composition And Activity In Streams, Miguel Rojas

Master's Theses

Microbial biofilms can be found on virtually all submerged surfaces in aquatic habitats, including rivers and streams. Biofilms are complex, taxonomically diverse communities of microorganisms (including algae and bacteria) that colonize solid surfaces and support a wide range of metabolic activities. Biofilms are critical components of river and stream ecosystems because they are key drivers of nutrient cycling processes (including nitrogen cycling) and because they serve as an important food source for higher trophic levels. Biofilms in urban streams are subject to a number of anthropogenic stressors, but research on the ecology of urban biofilms and their response to stressors …

Role Of Pkc Delta In Uv Radiation Dna Damage Repair, Gargi Patil

Master's Theses

DNA damage caused by ultraviolet radiation (UV), such as cyclobutane pyrimidine dimers (CPD), is repaired by the nucleotide excision repair (NER) pathway. When NER is defective, DNA damage is not repaired, leading to mutations and skin cancer. After DNA damage, the cell cycle is halted at various checkpoints to allow time for repair of the damage and maintain genomic integrity, however little is known about the coordination between NER DNA damage repair and cell cycle halting at checkpoints after DNA damage. Protein kinase C δ (PKCδ) plays major role in apoptosis and maintains the G2/M checkpoint in response to UV …

Lactobacillus Crispatus Produces A Bacteridical Molecule That Kills Uropathogenic E. Coli, Katherine Diebel

Master's Theses

As many as 1 in 2 women will have at least one urinary tract infection (UTI) in their lifetime. UTIs can cause complications in pregnancy and decrease quality of life, and their treatment and prevention are expensive. Uropathogenic E. coli (UPEC) is the primary cause of UTI. The probiotic and bactericidal capacities of gut and vaginal Lactobacillus isolates have been studied, but the same attention has not been paid to urinary strains. These urinary isolates of L. crispatus appear to have a greater killing capacity against UPEC and this bactericidal activity does not depend on the cells themselves, consistent with …

Examining Urban African American Adolescent Perceptions Of Neighborhood And Time Spent In Risky Contexts: Cross-Sectionally And Longitudinally, Kevin Michael Miller

Master's Theses

The purpose of the current study was to cross-sectionally and longitudinally examine the relationship between adolescent perceptions of their neighborhood and time spent in “risky contexts.” Specifically, the relationship between adolescent perceptions of neighborhood danger and the percent of time spent with older peers or outside was examined. In addition, this study analyzed the relationship between youth perceptions of neighborhood support and the percent time they spent with older peers or outside. All these relationships were also explored in regard to the moderating impact of gender and parental monitoring. An Experience Time Sampling technique (ESM) was utilized to determine how …

Defining The Role Of A Putative Peptidase In Staphylococcus Aureus Quorum Sensing And Pathogenesis, Chelsea Rose White

Master's Theses

The pathogenic bacterium Staphylococcus aureus encounters a variety of immune cells that restrict bacterial growth and dissemination during infection. However, S. aureus counters these immune cell functions by producing myriad virulence factors that facilitate evasion of host defenses. Therefore, it is important to understand S. aureus-immune cell interactions and the virulence factors that perturb normal immune function to promote pathogenesis. In a genetic screen designed to identify S. aureus secreted factors that modulate macrophage activity our lab identified a transposon insertion mutant in the gene SAUSA300_1984, encoding a putative membrane spanning peptidase. To investigate the role of 1984 in pathogenesis, …

The Role Of C-Abl Kinase In Hcc Development, Lennox Chitsike

Master's Theses

Hepatocellular Carcinoma is the second most lethal cancer after pancreatic cancer. Unresectable HCC tumors carry a poor prognosis and few treatment options are available. The dismal prognosis is mainly due to limited therapy options and molecularly targeted therapy is deemed as solution. Here, we report a novel role of c-Abl in HCC development. We provide evidence of c-Abl activation in human HCC samples compared to normal liver. Using genetic and pharmacological tools, we show that c-Abl plays a vital role in HCC progression in vitro and in vivo. We have identified Axl as an effector in processes mediated by c-Abl. …

Cellular Consequences Of Lysosomal Rupture Induced By Alpha Synuclein, Zachary Carpenter Green

Master's Theses

Misfolded, toxic forms of amyloid alpha synuclein (α-syn) have been implicated in Parkinson’s disease (PD) pathology and have been shown to spread throughout the brain in a prion-like manner, explaining the progressive loss of neurons in PD. The mechanisms of spread and cell death are unknown, however, evidence from previous studies suggests that neurons may undergo apoptosis due to the uptake of exogenous α-syn aggregate through the endocytic pathway and subsequent lysosomal rupture.

This study aimed to corroborate previous evidence of α-syn induced lysosomal rupture and investigate the cellular repercussions of rupture with respect to cell death and α-syn transfer. …

The Church And The Body, Kristina Russie

Master's Theses

Regulation Of Gonad Morphogenesis In Drosophila Melanogaster By Broad Complex, Tramtrack And Bric À Brac Transcription Factors, Diane Silva

Master's Theses

During embryogenesis, primordial germ cells (PGCs) and somatic gonadal precursor cells (SGPs) migrate and coalesce to form the early gonad. A failure of SGPs and PGCs to form a gonad with the proper architecture not only affects germ cell development, but also can result in infertility. We have characterized the phenotypes of two genes, longitudinals lacking (lola) and ribbon (rib), required for the coalescence and compaction of the embryonic gonad in Drosophila melanogaster. Both rib and lola are expressed in the SGPs and to a lesser extent in the PGCs of the developing gonad, and genetic interaction analysis suggests these …

Music And Aggression: Effects Of Lyrics And Background Music On Aggressive Behavior, Andrew Triplett

Master's Theses

Given the ever-growing popularity of music in daily life, it is of the utmost

importance to understand how it influences affect, cognition, and behavior, especially given the violence of certain genres of music. The present study was designed to investigate the relationship between music and behavior, specifically to examine how the lyrics and background music interact to influence affective hostility and aggressive behavior. Data were collected from a sample of 168 students (61% Female; MAge = 19.24, SD = 2.470) at a large, private, Midwestern university to investigate this relationship. The music was manipulated by randomly assigning the participant to …

Psychological Predictors Of Community Violence Exposure In Ethnic Minority Male Adolescents, Amanda Burnside

Master's Theses

Urban, minority males are disproportionately impacted by community violence exposure (ECV). However, person-based analyses have demonstrated variability in rates of ECV, suggesting that demographic risk factors do not always result in increased ECV, and it may be important to examine the utility of psychological factors in this relationship. Research suggests that depressive symptoms may actually exacerbate the risk of ECV. The current study examines the effect of internalizing symptoms on future ECV. Data were derived from a larger longitudinal study of adolescents who had committed a criminal offense. This subset of 184 participants ranged in age from 14-18. Results indicated …

In Plain Sight: How Social Images In Education Shape The Social Identity Of Black Students, Kandyce Cabacar

Master's Theses

This thesis will postulate social identity development in Black students is shaped by their school experience. Reviewing how racial grouping is a critical factor in how we engage with others socially, this study will curate the variables of society that assembles the Black image. Social construction influenced by media messages and the neighborhoods that determine our respective schools will also be analyzed. By borrowing from the research of social psychology and contributions of sociologists on race relations, this thesis will demonstrate how expectations influenced by racial stereotypes of Black students create a correlation to social identity. These findings are discussed …
