Trail Vision: Utilizing Leopold As Environmental Equipment For Living, Kendall Elizabeth Barrett

Master's Theses

Hiking trails are one of the major ways citizens make observations about the natural world. An analysis of trail maintenance texts demonstrates a focus on concealment and camouflage of human construction and upkeep in National Scenic Trails. These practices are detrimental to environmentalism, since the resulting ideology frames nature as overly self-sufficient and not in need of human stewardship. Trail maintenance practices are analyzed in reference to the nature/culture dichotomy. Perceptions of nature’s self-healing ability are analyzed through a comparison of the oil spills in Santa Barbara during 1969 and 2015. An alternative approach is found through Aldo Leopold. Leopold …

Living Between Borders: Transnational Marriage And Us Resettlement Patterns In Sudanese Refugee Populations, Deirdre Patterson

Master's Theses

Many South Sudanese refugees who have resettled in the USA have actively sought to maintain their unique cultural identity while simultaneously working to integrate into American society through the pursuit of formal higher education and successful careers. One of the most interesting developments within this population is the establishment and maintenance of transna- tional families. The process for marriage is economically tiresome and, due to strict immigration policies, often compels family members to live transnational lives. Systems of transnational mar- riage—often arranged by families—and married life allow Sudanese refugees living in the USA to continue important cultural practices, speak their …

Laff-O-Tron: Laugh Prediction In Ted Talks, Andrew D. Acosta

Master's Theses

Did you hear where the thesis found its ancestors? They were in the "parent-thesis"! This joke, whether you laughed at it or not, contains a fascinating and mysterious quality: humor. Humor is something so incredibly human that if you squint, the two words can even look the same. As such, humor is not often considered something that computers can understand. But, that doesn't mean we won't try to teach it to them.

In this thesis, we propose the system Laff-O-Tron to attempt to predict when the audience of a public speech would laugh by looking only at the text of …

Using a case study approach, it contributes original research to existing scholarship on Mathews, as well as the history of art education, the rise of women artists, and male feminism in the United States. By synthesizing primary sources from the 1890s related to Arthur and Lucia Mathews, the Académie Julian, the San Francisco School of Design, the San Francisco Sketch Club, and the San Francisco Commission for the Suppression of Vice, it presents new insights …

Stakeholder Engagement In Marine Protected Area Network Planning In Southern California: Understanding Fishing, Government, And Environmental Perspectives, Nicole Catalano

Master's Theses

This study focuses on the MPA network planning process associated with California’s Marine Life Protection Act (MLPA) in southern California, occurring between 2008-2009. This case study demonstrates the ongoing complexity of MPA planning efforts in balancing social and science goals and reinforces the view that public participation alone may not be sufficient in achieving the type of stakeholder support needed for successful MPA implementation. Using a qualitative approach, this research draws upon the field of public participation to examine the efficacy of the planning process from the perspectives of fishing, government, and environmental stakeholders. Findings reveal significant differences in perceptions …

The Role Of Psychological States In Predicting Work Engagement: A Test Of Kahn's Model, Taylor Gatti

Master's Theses

Researchers have consistently found engagement to be linked to positive individual and organizational outcomes such as job satisfaction, job performance, customer satisfaction, and productivity. Although task characteristics, transformational leadership, and core self-evaluations have been found to be important determinants of engagement, the mechanisms of why they are related to engagement are not well understood. Kahn (1990) argues that individuals become engaged through three psychological states: meaningfulness, safety, and availability. Using Kahn’s theory, the present study was conducted to test whether task characteristics, transformational leadership, and core self-evaluations were related to engagement through its respective psychological state. Data were collected from …

Experiments With And Implementation Of A Context Sensitive Text Summarizer, Charles Joseph Bocage

Master's Theses

Automatic text summarization is the ability to obtain key ideas from a text passage using as few words as possible. With the increase in data on the web, manual summarization of web pages has become unfeasible, and the need for automatic text summarization has become ever greater. This project explored and implemented various parts of the automatic text summarization process for an open source search engine, Yioop. These parts included stemming, text segmentation, term frequency weighting, automatic sentence compression, and content management system detection.

In addition, experiments were conducted on different pre-existing Yioop summarizers. These results served as a baseline …

Identifying Association Between Pedestrian Safety Interventions And Street Crossing Behavior Considering Demographics And Traffic Context, Franklin J. Caraballo

Master's Theses

Pedestrian fatalities are becoming a larger percentage of overall fatalities in the United States, therefore pedestrian safety research is essential for understanding and improving pedestrian safety. Pedestrian safety interventions are often used to educate and consequently improve pedestrian behavior. This study used pedestrian safety interventions to assess their effect on the respondents’ stated crossing behavior. Also, specific demographic data was used in this study to identify behavioral trends regarding street crossing behavior. The results show that pedestrian safety interventions are significantly associated with changes in pedestrian crossing behavior. The effect of the interventions was predominantly positive, since the respondents’ behavior …

Scaled Synthetic Aperture Rader Development, Jason Garvey Schray

Master's Theses

Several previous Cal Poly thesis projects involve synthetic aperture radar (SAR), automatic target recognition (ATR), and tracking. SAR data was either accessed from a publicly available database or generated using complex computer modeling software. The motivation for this dual thesis project is to design and construct a scaled SAR system to support Cal Poly radar projects. Ideally this is a low-cost, high resolution SAR architecture that produces raw range Doppler data for any desired target area. To that end, a scaled SAR system was successfully designed, built, and tested. The current SAR system, however, does not perform azimuthal compression and …

Inquiry Of Graphene Electronic Fabrication, John Rausch Greene

Master's Theses

Graphene electronics represent a developing field where many material properties and devices characteristics are still unknown. Researching several possible fabrication processes creates a fabrication process using resources found at Cal Poly a local industry sponsor. The project attempts to produce a graphene network in the shape of a fractal Sierpinski carpet. The fractal geometry proves that PDMS microfluidic channels produce the fine feature dimensions desired during graphene oxide deposit. Thermal reduction then reduces the graphene oxide into a purified state of graphene. Issues arise during thermal reduction because of excessive oxygen content in the furnace. The excess oxygen results in …

Gender In 17th Century Southern New England, Megan K. Willison

Master's Theses

This thesis, written in the form of two broadly related articles, aims to address questions related to topics of gender, identity, cultural change and continuity, and the materiality of social institutions. Each article investigates how artifacts, as physical objects unintentionally or purposefully discarded, represent and reflect human behavior, societal ideologies, and cultural infrastructures. Using primary sources, archaeological evidence, and linguistic data, each article proposes that certain artifact classes are representative of larger societal ideals and cultural mores, such as gender systems and ways of defining one's gender identity. The first article studies these topics through the analysis of funerary remains …

The Causes Of Regional Sea-Surface Temperature Anomalies During Wind Relaxation Events Off The U.S. West Coast In Summer, Kayla Flynn

Master's Theses

The term ‘wind relaxation’ describes weakening or reversal of the prevailing upwelling-favorable winds. Summertime wind relaxations along the U.S. West Coast exhibit an ‘event cycle’ spanning ~12 days. The winds first relax or reverse off the coast of Oregon. Next, the upwelling-favorable winds strengthen off the coast of central California; the strong winds move poleward and reach Oregon in ~3 days. Then the winds relax off central California. This previously known synoptic scale pattern in the momentum flux from atmosphere to ocean has led to two questions: 1) How does sea-surface temperature (SST) respond on scales of 100s to 1000s …

The Self Relevance Of Stigma: The Impact Of Weight Stigma On Normal Weight Women's Health Cognitions, Paige Martinez

Master's Theses

Previous research has demonstrated that weight stigma is associated with negative health outcomes among women who are overweight; this effect has been shown in both experimental and longitudinal studies. However, normal weight women do not tend to experience negative health impacts from exposure to weight stigma. This study attempted to manipulate the self-relevance of weight stigma among 150 normal weight women, in order to test whether self-relevance of stigma has an impact on health cognitions. Limited support for this framework was found.

Understanding How Intentionally Unplugging From Cell Phones Shapes Interpersonal Relationships And The Undergraduate College Experience, Jadelin P. Felipe

Master's Theses

The purpose of this study was to gain an understanding of what motivated college students—the Unplugged Students—to intentionally use their cell phones less and how they understood the impact that unplugging had on their interpersonal relationships and college experience. Nine undergraduate college students from four private schools were interviewed in one-on-one semi- structured interviews. These students, considered non-users, provided a particularly useful perspective as these students made a conscious choice to counteract social norms and experienced both being plugged in and unplugged. Cell phones and the act of unplugging proved to make up a complex and more nuanced topic than …

Micro-Grid Reliability Modeling And Analysis Approaches, Xiaofang Shi

Master's Theses

Micro-grids are becoming of more interest worldwide to achieve reliable electrical energy infrastructure during natural hazards and catastrophic situations due to their ability to operate in both grid-connected and islanded modes. They typically include distributed generation resources that could provide heat and electricity and are expected to have significant clean energy penetration.

Micro-grid system reliability is critical for system design and maintenance since it is commonly used as a backup power system especially during the main grid blackouts or failures. The study of micro-grid reliability can give system designers, operators, and customers potential failure modes of its subsystems and components …

Hydrologic Characteristics Of Summer Stream Temperatures In Little Creek And Scotts Creek At The Swanton Pacific Ranch, Justin M. Louen

Master's Theses

Stream temperature impacts have resulted in increased restrictions on land management such as timber harvest and have created considerable uncertainty for future planning and management of redwood forestlands. Challenges remain in the assessment of downstream cumulative effects given the complexity of stream temperature dynamics. The goal of this research is to identify the risk of downstream temperature heating based on the summer low flow residence times, stream morphological characteristics, stream water storage, and heat budget exchanges. Stream temperature, hydrologic, climatic, and channel morphological data were collected on two, approximately 800 m stream reaches on Little Creek and Scotts Creek located …

Risk-Based Approach To Assessment Of Advanced Technologies For Conceptual Design, Adipratnia Asmady

Master's Theses

The conceptual design phase of an aerospace system development program is typically characterized by short duration and relatively limited resources, yet design decisions are made that have critical implications on program risk. To address the more aggressive requirements, one of these decisions is the selection of advanced technologies. System developers need to assess advanced technologies early on, but are faced with uncertainties surrounding the potential net benefits. The concept introduced in this study is uncertainty characterization as a way to better understand the associated risk. A framework was developed to guide the interaction between the technology developer and the system …

These measurements were taken over diurnal cycles using a LICOR LI-8100A automated soil gas flux system with long term chambers. SR rates and soil temperature measurements were collected during 3 sampling periods in 2012 and 1 sampling period …

"Your Reclamation”: The Gothic Child And Moral Restoration In Charles Dickens’S A Christmas Carol, Ashten Roberts

Master's Theses

Charles Dickens’s A Christmas Carol (1843), an example of Victorian Gothic literature, portrays spirits escorting Ebenezer Scrooge on a journey through time in order to transform him from a miser to a benefactor. Dickens’s text has received much critical attention, and while most critics agree that the novella includes various elements of the gothic, few draw attention to the possibility of the child characters as gothic elements. I argue that Carol’s child characters can be read in terms of what Margarita Georgieva calls “the gothic child.” According to Georgieva, the gothic child can be an adult’s memory from childhood …

Establishing A Link Between Personality And Social Rank In A Group Of Bottlenose Dolphins (Tursiops Truncatus), Erin Elizabeth Frick

Master's Theses

Bottlenose dolphins (Tursiops truncatus) have been documented to possess personality traits that remain consistent over time (Highfill & Kuczaj, 2007) and across contexts (Kuczaj, Highfill, & Byerly, 2012). Such individual differences are thought to play an important role in various social contexts such as hierarchical dominance (Highfill & Kuczaj, 2010). The present study investigated the relationship between personality and social rank within a captive group of bottlenose dolphins housed at the Roatan Institute for Marine Science (RIMS). Social rank was established using questionnaires distributed to the RIMS experienced staff. Personality traits were derived from behavioral coding using context-specific …

The Invisible People Of The Invisible Coast: The Resilience Of People Experiencing Homelessness To Disasters On The Alabama, Louisiana, And Mississippi Gulf Coasts, Nicole Elizabeth Callais

Master's Theses

While extensive research has been conducted on vulnerability and resilience with regard to hazards, very few studies have researched the resilience of homeless populations. The Gulf Coast region is densely populated and susceptible to natural and anthropogenic hazards. Climate change studies indicate that this region will experience an increase in severe and intense tropical cyclones[1], thereby increasing the risk of experiencing adverse impacts from future coastal hazards. While local government agencies in this region have policies in place to protect communities, these policies tend to exclude any action regarding the evacuation and safety of the homeless population.

"Too Big To Swallow All At Once": Consumption And Posthuman Healing In Ceremony And House Made Of Dawn, Matthew Thomas Craft

Master's Theses

This project examines the roles of animals and animal figures in the Native American novels House Made of Dawn (1968)by N. Scott Momaday and Ceremony (1977) by Leslie Marmon Silko. Both novelists consistently evoke animal imagery within their respective texts often pairing this imagery alongside symbolic and metaphorical depictions of cannibalistic identity violence. Through the use of posthuman and postcolonial methodologies and ideas, I contend that the pairing of these two distinct types of imagery that both Momaday and Silko intentionally align the animal figures with premodern, indigenous belief systems while the cannibalistic violence is more often envisioned as …

The Effectiveness Of Periodically-Harvested Closures In Meeting Ecological And Socioeconomic Objectives, Paul G. Carvalho

Master's Theses

Periodically-harvested fisheries closures (PHCs) are a widespread form of community-based marine spatial management used throughout the Indo-Pacific that also is currently being intensively advocated by conservation organizations for supporting productive fisheries and healthy marine ecosystems. However, local implementation of PHCs has historically been designed to support occasional and efficient exploitation of fish stocks, and not necessarily sustainable fisheries yields and stock conservation. The efficacy of PHCs for achieving their historical cultural objectives of periodicity and efficiency of harvest, simultaneously with achieving contemporary fisheries objectives of fisheries productivity and conservation is undetermined. As a result, the utility of PHCs for supporting …
