Achieving Relationships, Frederick C. Melancon

Master's Theses

These stories attempt to follow John Gardner’s instruction to create a dream that will engage the reader. Mirroring the goal that an author has to create a relationship with his audience, each story in turn focuses on emotional details that convey the characters’ feelings of isolation or, alternatively, inclusion in their communities. In the first story, a young man tries to recreate his father’s king cake. In the next, a middle school girl fixates on her relationship with her sister. Trying to recapture the memory of a lost daughter, a man searches for the perfect nectar snowball. A mom, then, …

Development And Validation Of A Survey Of Knowledge Of Autism Spectrum Disorder, Laura Katherine Hansen

Master's Theses

As autism spectrum disorder (ASD) is more commonly diagnosed, having knowledge of the disorder becomes increasingly important for educators, parents, and the general public. Previous research regarding knowledge of ASD, focused mainly on knowledge possessed by those in the educational field, has found that individuals may perceive themselves as possessing average knowledge regarding ASD but have low actual knowledge (as defined by the researchers) regarding specific aspects of the disorder (Williams et al., 2011). Studies support the notion that there is a general lack of knowledge of different aspects of ASD among teachers; however, there has been little research regarding …

Recreation Ecology Of Colorado Fourteeners: An Assessment Of Trail Usage And Impacts, James C. Ewing

Master's Theses

The popularity of climbing Colorado’s 14,000 ft. peaks, or “Fourteeners”, has risen dramatically in recent years, raising important sustainability and management questions. Moreover, groups managing the peaks operate with major capital constraints so their efforts need to be informed, prioritized, and efficient. This paper gauges the dynamics of trail usage, explanatory variables, and recreational impacts across all 58 Fourteeners, and details evaluation adjustments that minimize error and produce results in-step with the resource management framework. Relative to a baseline study completed in 2005, substantial changes occurred in trail usage and impact dynamics. The greatest changes were concentrated on peaks previously …

Maternal History Of Childhood Sexual Abuse And Adolescent Sexual Risk Behaviors: Potential Mechanisms Of Intergenerational Effects, Sanne N. Wortel

Master's Theses

Almost a quarter of women experience some kind of childhood sexual abuse (CSA). Although CSA is associated with subsequent difficulties in women’s sexual well-being and parenting, few studies have examined whether maternal CSA history impacts how parents navigate the sexual development of their children. Using a cross-sectional sample of 194 low-income adolescents girls (Mean age = 15.4), the goal of this study was to: 1) test whether maternal CSA is predictive of adolescent sexual risk behaviors (SRBs), and 2) identify parenting/family characteristics (sexual communication, sexual beliefs, parental monitoring and autonomy granting, and mother-daughter relationship quality) that may mediate this relationship. …

Lyme Disease Ecology In San Luis Obispo County: The Role Of The Western Gray Squirrel, Ryan William Baker-Branstetter

Master's Theses

Despite the fact that eight cases of Lyme disease were diagnosed in San Luis Obispo County between 2005-2013, the identity of wildlife hosts serving as sources for tick infection in this region remained unidentified. The primary cause of Lyme disease in the U.S. is the spirochetal bacterium Borrelia burgdorferi sensu stricto, and this agent had not been previously isolated from the region. Borrelia bissettii, a related species that has not been implicated as a common causative agent of Lyme disease, was isolated in small rodents inhabiting coastal scrub and chaparral habitats in a previous San Luis Obispo County study. However, …

The Influence Of Organizational Personality And Social Identity Consciousness On Organizational Attraction: A Humanness Perspective, Xiaoyuan (Susan) Zhu

Master's Theses

Organizational affiliations serve a social identity function for employees because others will typically infer information about them based on their place of employment. To the extent that job seekers are concerned about these inferences, they will attempt to maintain a positive social identity by joining organizations they believe are viewed as favorable by the public. Research has examined whether social identity needs interact with organizational personality perceptions (i.e., a type of symbolic inferences) but with some inconsistent findings. I argue that the existing organizational personality taxonomy may suffer from bandwidth correspondence issues that may be attenuating large interaction effects. In …

Quantification Of Blood Flow Velocity Using Color Sensing, Aditya Deepak Sanghani

Master's Theses

Blood flow velocity is an important parameter that can give information on several pathologies including atherosclerosis, glaucoma, Raynaud’s phenomenon, and ischemic stroke [2,5,6,10]. Present techniques of measuring blood flow velocity involve expensive procedures such as Doppler echocardiography, Doppler ultrasound, and magnetic resonance imaging [11,12]. They cost from $8500-$20000. It is desired to find a low-cost yet equally effective solution for measuring blood flow velocity. This thesis has a goal of creating a proof of concept device for measuring blood flow velocity.

Finger blood flow velocity is investigated in this project. The close proximity to the skin of the finger’s arteries …

Clarifying The Role Of Social Support In The Relationship Between Stressors And Strains At Work: The Effect Of Self-Construals, Maria Joao Subtil De Carvalho

Master's Theses

Practitioners and researchers often focus on social support to allay occupational stress, despite inconsistent results from empirical studies. This longitudinal study examined the impact of nurses’ self-construals on the effect of social support on the relationship between stressors and outcomes, based on research showing that people in individualistic and collectivistic cultures perceive supervisor and coworker support differently and research showing culture is internalized as self-construals. The aim of the study was to identify circumstances in which social support mitigates stress. Survey data were collected at two points in time (about four weeks apart), from 139 nurses in two northern California …

The Effects Of Gender, Physical Attractiveness, And Socioeconomic Status On Initial Attraction, Sherrie Jagolino

Master's Theses

The tradeoff threshold model posits that in a heterosexual relationship, high socioeconomic status (SES) can compensate for physical unattractiveness in men, whereas physical attractiveness can compensate for low SES in women. In the present study, we attempted to provide evidence for the tradeoff threshold model. Ninety-six heterosexual participants viewed eight high and low attractive male or female stimuli photographs each attached with high or low SES descriptions. Average physical attractiveness ratings were analyzed in a 2 (physical attractiveness: high and low) x 2 (SES: high and low) repeated measures analysis of variance (ANOVA) for each gender. Women rated low SES …

The Interactive Effects Of Accent, Attire, And Job Status On Employment-Related Decisions, Bonnie Nguyen

Master's Theses

Using data from 207 college students, the interactive effects of an applicant’s accent (standard American English vs. Arabic), attire (no hijab vs. hijab), and job status (low vs. high) on perceived applicant characteristics (i.e., competence and warmth) and employment-related decisions (i.e., job suitability and hiring recommendation) were examined. Inconsistent with the hypotheses, results showed that an Arabic-accented and an applicant wearing a hijab were not rated as less competent and warm compared to a standard American-accented applicant and an applicant not wearing a hijab, respectively. Additionally, an Arabic-accented applicant wearing a hijab was not perceived as less competent and warm. …

The Moderating Effect Of Supervisory Social Support On The Relationship Between Second Generation Latinos’ And Asians’ Assimilation Level And Work-Family Conflict, Yazmin Perez-Lopez

Master's Theses

The majority of the empirical work regarding work-family conflict (WFC) has been focused on the experiences of White, middle class, Anglo-Americans. The labor force, however, is experiencing major demographic changes as increasing numbers of U.S.-born Latinos and Asians become employees. Although second generation Latinos and Asians play a major role in the U.S. economy and workplace, their experiences as employees have seldom been examined. Because they are exposed to collectivistic and individualistic values simultaneously, their assimilation levels, or identification with the U.S. culture, could be a unique predictor of a type of WFC: work-interference with family (WIF) or family interference …

Generational Differences In Perceived Supervisory Support, Ashraf Rayani

Master's Theses

As Baby Boomers, Generation X and Generation Y interact with each other in the workplace, popular media and HR practitioners have suggested ideas on how to promote these groups to work cohesively under one organizational umbrella. Beyond encouraging the partnership of these three generations, it is also important for organizations to understand how these three generational cohorts differ in the level of support they receive from their supervisors. Therefore, the current study bridged that research gap by investigating differences in perceived supervisory support across the three generational cohorts. An online employee engagement survey was administered to 935 business professionals from …

The Effect Of Distractions On Task Performance And Enjoyment As Moderated By Regulatory Fit, Kimberly Leung

Master's Theses

Every day, distractions keep people from maintaining focus and productivity. Music, in particular, is a distraction that can easily disrupt individuals mentally and physically. However, what if common distractions like music had the power to motivate people towards a goal rather than deter them from it? Regulatory Focus Theory offers an explanation for how this is possible. It posits two motivational foci: promotion and prevention. If individuals are promotion-focused, they seek positive outcomes, and if individuals are prevention-focused, they try to avoid negative outcomes.

The current study tested the assumption that avoiding distractions during goal pursuit matched the behavior of …

An Investigation Into Partitioning Algorithms For Automatic Heterogeneous Compilers, Antonio M. Leija

Master's Theses

Automatic Heterogeneous Compilers allows blended hardware-software solutions to be explored without the cost of a full-fledged design team, but limited research exists on current partitioning algorithms responsible for separating hardware and software. The purpose of this thesis is to implement various partitioning algorithms onto the same automatic heterogeneous compiler platform to create an apples to apples comparison for AHC partitioning algorithms. Both estimated outcomes and actual outcomes for the solutions generated are studied and scored. The platform used to implement the algorithms is Cal Poly’s own Twill compiler, created by Doug Gallatin last year. Twill’s original partitioning algorithm is chosen …

Demographics And Transfer Of Escherichia Coli Within Bos Taurus Populations, Joshua Ryan Dillard

Master's Theses

In the United States, symptoms caused by pathogenic strains of Escherichia coli are on the rise. A major source of these pathogenic strains is the E. coli in the digestive tract of cattle. The purpose of this project was to determine if E. coli are transferred between individuals of the same species and if interspecies transmission is possible. Proximity of cattle was also studied as a contributing factor to the transfer of E. coli. To accomplish this goal, E. coli isolates from cattle and cohabitating ground squirrels were compared through a new method of bacterial strain typing called pyroprinting. …

A Hybrid Approach To General Information Extraction, Marie Belen Grap

Master's Theses

Information Extraction (IE) is the process of analyzing documents and identifying desired pieces of information within them. Many IE systems have been developed over the last couple of decades, but there is still room for improvement as IE remains an open problem for researchers. This work discusses the development of a hybrid IE system that attempts to combine the strengths of rule-based and statistical IE systems while avoiding their unique pitfalls in order to achieve high performance for any type of information on any type of document. Test results show that this system operates competitively in cases where target information …

Cognitive Video Streaming, Devaki Rani Pasupuleti

Master's Theses

Video-on-demand (VoD) streaming services are becoming increasingly popular due to their flexibility to allow users to access their favorite video contents anytime, anywhere from a wide range of access devices such as smart phones, computers and TV. The content providers rely on highly satisfied subscribers for revenue generation and there has been significant efforts in developing approaches to “estimate” the quality of experience (QoE) of VoD subscribers. But a key issue is that QoE is not defined, appropriate proxies needs to be found for QoE, via the streaming metrics (the quality of service (QoS) metrics) that are largely based on …

Enzyme Level N And O Isotope Effects Of Assimilatory And Dissimilatory Nitrate Reduction, Lija Treibergs

Master's Theses

Nitrate N and O isotope distributions in the environment can be used to elucidate salient biogeochemical N transformations. In order to do so, it is necessary to know the isotopic imprints characteristic of respective N transformations, and to understand the underlying mechanisms that determine these patterns. In order to provide mechanistic constraints on the isotopic imprints associated with nitrate consuming processes, we measured the enzymatic N and O isotope effects (¹⁵ε and ¹⁸ε) imparted on nitrate by three types of nitrate reductase enzymes, including (a) a prokaryotic respiratory nitrate reductase, Nar, from the heterotrophic denitrifier Paracoccus …

Crowdsourcing Real-Time Traveler Information Systems, Asif Rehan

Master's Theses

In the last decade, the concept of collecting traffic data using location aware and data enabled smartphones in place of traditional sensor networks has received much attention. With a steady market growth for smartphones enabled with GPS chipsets, the potential of this technology is enormous. This combined with the pervasion of participatory paradigms such as crowdsourcing wherein individuals with portable sensors instead of physical networks serve as sensors providing information. Crowd sensed data overcome a number of issues with traditional physical sensor networks by providing wider coverage, real-time data, data redundancy and cost effectiveness to name a few. While there …

"Equal Partners In Crime": Narration In The Brief Wondrous Life Of Oscar Wao, Rebecca Mae Holder

Master's Theses

This reading of Junot Díaz’s The Brief Wondrous Life of Oscar Wao argues that narrator Yunior’s failure to capture the authentic speech of Beli illuminates the failure of narrative generally to speak authentically for the subaltern. The writings of Mikhail Bakhtin, Gayatri Spivak, and Scott McCloud work together to uncover the political and ethical implications of Yunior’s willful erasure of Beli’s voice. In the sections detailing her early life, Yunior draws attention to the gaps in the information he gives readers and thus reminds them that all narrative excludes and distorts details to fulfill an objective. This reading argues that …

The Masculine Mystique, Michael W. Chancellor Jr.

Master's Theses

This textual analysis explores the rhetoric of exclusion among homosexual men by analyzing DouchebagsofGrindr.com. The rhetoric of exclusion is used by some homosexual men in order to achieve hegemonic masculinity based on performance of gender, age, race, and physical characteristics to conquer stereotypes of femininity. The gay community utilizes civil rights rhetoric in order to create a dialogue about equality; unfortunately a disturbing number of gay community members frequently discount homosexual male minorities, perpetuating the notion that homosexual minorities are unattractive because they violate heteronormative gender performances. Analyzing the artifact DouchebagsofGrindr.com allows for a glimpse into the self-deprecating online behavior …

A Poetic Poioumenon: Coterie And Ekphrasis In David Lehman's "The Breeders' Cup", Anna Beth Rowe

Master's Theses

David Lehman’s poem “The Breeders’ Cup” uses cross-generational coterie and ekphrasis to create a poetic poioumenon. When read in terms of art criticism, Lehman’s “The Breeders’ Cup” models creative processes from the past and calls for a rehabilitative ethic in postmodern poetics. Lehman follows the ekphrastic form, which associates a poem with a work of visual art, from his New York School predecessor Frank O’Hara. “The Breeders’ Cup” addresses Édouard Manet’s 1865 painting Olympia through ekphrasis, and the painting of a prostitute becomes a patron saint of parody for postmodern poetics. The poem introduces lust as a metaphor for creative …

Evaluation Of The Protein Recognition Properties Of Peptide Nucleic Acids, Crystal Cox Serrano

Master's Theses

The objective is to evaluate the ability of aminoacyl-tRNA synthetases (aaRS) to recognize the non-standard nucleic acid, PNA (peptide nucleic acid). PNA has immense potential in biomedical applications due to its increased thermostability and nuclease resistance over natural nucleic acids. PNA represents a superior alternative to natural nucleic acids in many biomedical applications due to its specificity, strong binding, and nuclease resistance. This study is the initial data set that indicates PNA are recognized by translation enzymes.
