To establish the foundation, this thesis uses a robust qualitative methodology, coupling a review of literature on the potential advantages and disadvantages of vehicle automation and lessons from past innovations in transportation, with recent trends of the Millennial Generation, …

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 …

Peering In: Improving Existing Buildings With Colorful Increments, Daire Heneghan

On the other hand, new office buildings’ adoption of new technologies and building philosophies offer a range of sustainable efficiencies previously unavailable. Combining these efficiencies with elements that embrace human diversity and well- being offer the opportunity to not only mend our existing buildings’ deteriorating physical bodies but aid in creating workplaces that promote good physical and mental health.

This project provides recommendation on how an existing high-rise commercial building can incorporate a number of incremental improvements that continually evolve to meet rapidly changing market …

Toward High Performance Nanocarbon Fibers, Michaela R. Pfau

Master's Theses

High performance carbon fibers (CFs) have been a commercially available since their commercial boom in the 1970s, and are generally produced via carbonization of poly (acrylonitrile) (PAN). More recently, carbon nanomaterials like graphene and carbon nanotubes (CNTs) have been discovered and have shown excellent mechanical, thermal, and electrical properties due to their sp² carbon repeating structure. Graphene and CNTs can both be organized into macroscopic fibers using a number of different techniques, resulting in fibers with promising mechanical performance that can be readily multifunctionalized. In some cases, the two materials have been combined, and the resulting hybrid fibers have …

Metrics Dashboard Services: A Framework For Analyzing Free/Open Source Team Repositories, Fnu Shilpika

Master's Theses

Software engineering as practiced today (especially in the industry) is no longer about the stereotypical monolithic life cycle processes (e.g. waterfall, spiral, etc.) found in most software engineering textbooks. These heavyweight methods historically have impeded progress for small/medium sized development teams owing to their inherent complexity and rather limited data collection strategies that predominated the 1980s until relatively recently in the mid-2000s. The discipline and practice of software engineering includes software quality, which has an established theoretical foundation for doing software metrics. Software metrics are a critical tool which provide continuous insight to products and processes and help build reliable …

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 …

Grit In The Classroom, David Anthony Vaughn

Master's Theses

In the United States today, educational opportunity is not equally distributed. Statistical data show a persistent educational achievement gap that disproportionately affects students of color or with a low socioeconomic status. There have been countless efforts to reform this inequality within the American school system; however, many efforts have ignored underlying issues regarding power structures and may instead be rooted in the biased beliefs of dominant culture. Knowledge is Power Program (KIPP) Public Charter Schools, in particular, emphasize seven character strengths that are intended to promote success for their students and bring them to and through college. Such traits may …

Use Of Youth Program Quality Assessment (Ypqa) As A Method Of Process Evaluation: Maximizing Limited Resources Of Nonprofit Organizations, Young Im

Master's Theses

Past literature shows the progression of different phases of evaluation practice in nonprofit organizations. Pressure of outcome or impact evaluation started the beginning of the 21st century. The attempt to manage the weight of conducting outcome evaluation has raised many complications, inhibiting the nonprofit organization’s ability to learn and understand the proper role of evaluation and what it can provide to assist in improving programs. It, therefore, has led to a gap in which nonprofits miss what happens during implementation, a crucial part of process evaluation. Among nonprofit organizations in the areas of youth development and after-school programs, various types …

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 …

Building And Optimizing A Spectroelectrochemical System For The Study Of Shewanella Putrefaciens, Jonathan Muscolino

Master's Theses

Shewanellaceae are among the most widely studied electroactive microorganisms. This study reports on Shewanella putrefaciens under anaerobic conditions during applied potential while monitored by spectroscopy. The attachment of the microbe Shewanella putrefaciens onto an indium tin oxide electrode was found to occur after 2 hr of +0.2 V applied potential. Microbial detachment occurred with a 5 mV/s scan rate cyclic voltammogram from +0.2 V to -0.5 V to +0.2 V. This was confirmed through use of a spectroelectrochemical apparatus utilizing a standard 3 electrode setup with evanescent wave spectroscopy.

I specifically seek to answer this research question: How were tracking policies in the German education system reshaped or addressed in education reforms after the end of World War I, World War II, and post-reunification? This is a historical study; thus, the data I collected came from a variety of primary and secondary sources relevant to the subject with the aim of …

Feminist And Gay Male Politics: New Issues For Political Collaboration And Activism, Adam Hii

Master's Theses

This project looks at political collaboration between people who self-identify as gay men

and those who self-identify as feminists. These two groups have been political aligned on numerous issues since the 1970s. The goal of this project is to see on which issues that political collaboration will continue moving forward. This research draws extensively on oral interviews conducted with gay men and feminists, as well as the current work of national advocacy organizations to see where political interest is high, and where networks already exist to foster future advocacy efforts. By focusing on these areas, this project predicts which issues …

A Bioluminescence Sensor Of Nlrp3 Inflammasome Activation, Michael Alexander Winek

Master's Theses

The innate immune system is many organisms first line of defense against pathogenic insult or tissue damage. This defense strategy is intent on restoring homeostasis upon perturbation. Upon activation of the innate immune system in humans, an oligomeric protein complex termed the “Inflammasome” forms in myeloid cells. The canonical output of activation of any subset of inflammasome is Caspase-1-mediated secretion of pro-inflammatory cytokines IL1β and IL18. Chronic or uncontrolled inflammasome activation is at the core of myriad economically burdening diseases. In many of these diseases, endogenous factors chronically engage the innate immune system. To study these diseases in in vivo, …

Phosphodiesterase Inhibition As A Mechanism Of Ion Channel Modulation By Celecoxib, Christina Jean Robakowski

Master's Theses

The overall objective of this thesis work is to determine the mechanism by which celecoxib modulates Kv7 potassium channels in vascular smooth muscle cells. The central hypothesis of the project is that celecoxib modulates Kv7 potassium channels in vascular smooth muscle cells through inhibition of phosphodiesterase 4 (PDE4, which catalyzes the breakdown of cyclic adenosine monophosphate (cAMP)), thereby activating a cAMP/protein kinase A (PKA) signaling pathway. The aims of this thesis targeted different points in the cAMP/PKA pathway with pharmacological interventions using whole cell perforated patch clamp electrophysiology and biochemical methods.

The data suggest multiple mechanisms by which celecoxib could …

Examining The Effects Of Coping Strategies Specific To Community Violence Exposure Among African American Adolescents, Suzanna So

Master's Theses

Variability in exposure to community violence (ECV) and aggressive behaviors in African American youth from urban communities can be attributed to general coping, but these studies have been inconclusive. Recent qualitative research identified four types of coping that are specific to ECV; however, quantitative research is needed to understand the adaptiveness of these strategies. The current study examined the factor structure of a measure for ECV-specific coping strategies. The current study also assessed how ECV-specific coping was associated with ECV and externalizing behaviors. Data from the current study were derived from an archival dataset comprised of 594 African American adolescents. …

Risk And Resilience Factors Among Low-Income Latino Adolescents: The Impact On Daily Ratings Of Mood, Stephanie Andrea Torres

Master's Theses

Given that Latino adolescents endorse more negative mood when compared to their counterparts of other backgrounds (CDC, 2012), it is especially advantageous to evaluate the impact of risk and resilience factors on mood among this population. The current study uses daily diary methodology to examine the impact that daily economic stress, daily family stress, familism, and ethnic identity commitment and exploration have on daily ratings of mood among 58 (M =13.31, 47% female) low-income Latino adolescents. Results show that daily family stress was strongly linked to daily mood while familism emerged as a salient resilience factor. Contrary to predictions, ethnic …

Adams As Potential Regulators Of Stem Cell Quiescence In The Olfactory Epithelium, Elaine Elizabeth Orendorff

Master's Theses

I demonstrate that a member of the protein family A Disintegrin and Metalloprotease (ADAM), ADAM23, is expressed in the olfactory epithelium (OE) and may inhibit neural progenitor cell (NPC) proliferation. I generated a list of ten gene candidates and selected ADAM23 for further study, based on its conserved protein structure and accumulating evidence for its role in cell cycle progression of proliferative cells. I next determined ADAM23 protein localization using immunohistochemistry and measured both mRNA and protein expression post-lesion with RT-qPCR and Western blot. ADAM23 is expressed in multiple cell types of the OE, including glial Sustentacular (Sus) cells and …

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 …

Spest – A Tool For Specification-Based Testing, Corrigan Redford Johnson

Master's Theses

This thesis presents a tool for SPEcification based teSTing (SPEST). SPEST is designed to use well known practices for automated black-box testing to reduce the burden of testing on developers. The tool uses a simple formal specification language to generate highly-readable unit tests that embody best practices for thorough software testing. Because the specification language used to generate the assertions about the code can be compiled, it can also be used to ensure that documentation describing the code is maintained during development and refactoring.

The utility and effectiveness of SPEST were validated through several exper- iments conducted with students in …

Simulating And Understanding A Summertime Dry Lightning Event In Coastal California, Philip Isaac Martin

Master's Theses

Thunderstorms are rare in coastal California during the summer months. Synoptic situations that encourage these summertime thunderstorms typically involve elevated instability that promotes dry lightning thunderstorms, where less than 0.1 in of precipitation reaches the ground. On 21 June 2008, a poorly forecasted dry lightning outbreak was responsible for starting more than 1,500 wildfires across California, and specifically the Monterey region. In this research, we used analysis data from the Global Forecast System (GFS) model to investigate the evolution of the synoptic conditions leading up to the outbreak. We then created two sets of ensembles with the Weather Research and …

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 …

Data Reduction Of A Shake-Table Experimental Study Of Architectural Precast Concrete Cladding, Kanotha Charles Kamau-Devers

Master's Theses

Two full-scale architectural precast concrete (APC) panels were tested in 2011 on a full-scale five-story steel frame building at the E-Defense shake table facility in Miki, Japan. The panels were designed according to common U.S. practice. The main issues evaluated were: 1) the effect of acceleration on the APC panels, and 2) the effectiveness of the current slotted-bolt sliding connection to allow for inter-story earthquake motion. The testing represented one type of standard US APC façade design where the APC panel is designed to accommodate inter-story drift through rocking. Instrumentation measured the acceleration of the panels and floors as well …

A Wholistic Model Of Apologetics For Equipping The Youth, Selim Kesmez

Master's Theses

Problem

While available studies indicate that biblical world view among young adults decreases in years of secular education Adventist education system in Germany is struggling to address the needs of the young adults. The question arises what kind of needs can be identified why they leave faith and church behind and how the Church may counteract this process and provide valuable assistance. The urgency of this question emerges in considering the high rate of de-conversion among Adventist youth.

Method

This study analyzes various studies and statistical reports regarding the condition of the spiritual life of young adults in both the …
