Distribution And Habitat Use Of The Santa Clara County Population Of Red-Bellied Newts (Taricha Rivularis), Joie De Leon Jul 2021

Distribution And Habitat Use Of The Santa Clara County Population Of Red-Bellied Newts (Taricha Rivularis), Joie De Leon

Master's Theses

Anthropogenically-induced habitat loss and degradation have increased extinction rates in amphibians worldwide, yet little is known about many remaining populations. A disjunct population of red-bellied newt (Taricha rivularis), an endemic California species, was discovered 130 km south of its previously known range. Here I document the range and breeding phenology of this population and contrast its mesohabitat use with that of other sympatric newts. Surveys across two years suggest that the southern population of T. rivularis is confined to a 1 km segment of Stevens Creek, and the population follows an early-March to late-April migratory breeding pattern, similar to one …

Perception Correction: Addressing Social Stigmatization Around Bdsm And Mental Health, Erin Afana Jul 2021

Perception Correction: Addressing Social Stigmatization Around Bdsm And Mental Health, Erin Afana

Master's Theses

Mainstream society’s characterization of activities and subgroups as abnormal can result in a long history of being shamed and pathologized, leading to discrimination and stigmatization. BDSM (bondage and discipline, dominance and submission, and sadomasochism) is an alternative lifestyle with a variety of identities, characteristics and practices that are viewed by many as being outside of societal norms. The consequences of this can be seen in how society, in general, views BDSM participants, how the criminal justice system responds to issues involving BDSM, and how the mental health system perceives those who participate in BDSM activities. The purpose of this thesis …


Evaluating Effect Of Folic Acid On Mouse Embryonic Fibroblast Cells With Impaired Dna Repair System, Suneeti Madhavan Jul 2021

Evaluating Effect Of Folic Acid On Mouse Embryonic Fibroblast Cells With Impaired Dna Repair System, Suneeti Madhavan

Master's Theses

Mandatory folic acid (FA) fortification programs have been introduced in many countries since 1998 [1]. This fortification program, especially when combined with vitamin supplements taken for health purposes, can lead to higher-than-normal levels of synthetic FA in the body [2]. Recent research has linked high levels of synthetic FA (more than the daily requirement of 400μg/day) with increased incidences of cancer [2-7]. In comparison, low levels of FA have been shown to cause DNA damage due to impaired DNA repair processes [8,9]. This study hypothesizes that increased levels of FA give rise to DNA modification. Therefore, if cells harbor an …

A Flat Plate Skin Friction Correlation Including Transition, Jaret M. Wedow Jun 2021

A Flat Plate Skin Friction Correlation Including Transition, Jaret M. Wedow

Master's Theses

Many existing boundary layer models treat transition as a rapid switch from laminar to turbulent flow, with correlations defining properties in each respective region. Natural transition, however, is not always a very spanwise uniform process, with the onset of transition varying somewhat between different streamwise paths of fluid flow. Thus, a spanwise average of natural transition can result in a more gradual, extended transition region than many existing models predict. Modern applications, such as aircraft wings and fuselages, are extremely streamlined and smooth, allowing for natural transition to occur rather than flow tripping to turbulent near the leading edge. Under …

Los Zetas, Neoliberalism, And Popular Opposition: A Study In Linkages, Gina R. Lyle Jun 2021

Los Zetas, Neoliberalism, And Popular Opposition: A Study In Linkages, Gina R. Lyle

Master's Theses

Los Zetas are considered by security analysts to be a transformative force within transnational criminal organizations (TCO), exporting their unique model throughout Mexico. Los Zetas’ idiosyncratic interventions include their diversification of criminal operations, professionalization of TCO security, sophisticated use of media and technology, extreme forms of violent coercion, and decentralized command structure. This project aims to complicate the narrative that Los Zetas emerged because of top leaders’ sadistic tendencies or due to an inherently violent culture in Mexico by reframing the group’s evolution within historical processes. Moving beyond Los Zetas, this project examines how persons affected by Los Zetas’ indiscriminate …


Upending The "Racial Death-Wish": Black Gay Liberation And The Culture Of Black Homophobia, Kailyn Pope Jun 2021

Upending The "Racial Death-Wish": Black Gay Liberation And The Culture Of Black Homophobia, Kailyn Pope

Master's Theses

This thesis analyzes the origin and impact of Black homophobia found in activist spaces of mid- to late-twentieth-century American society. Black gay Americans were subjected to intersecting forms of systemic and cultural oppression that were exceedingly hard to escape due to both the homophobia in Black spaces and the racism in gay spaces. Black gay activists and artists thus had to create their own avenues of expression where they and others could fully embrace what it meant to be Black and gay. This work utilizes a Black feminist framework to explore the roots of Black homophobia and how this type …

Leveraging Intermediate Artifacts To Improve Automated Trace Link Retrieval, Alberto D. Rodriguez Jun 2021

Leveraging Intermediate Artifacts To Improve Automated Trace Link Retrieval, Alberto D. Rodriguez

Master's Theses

Software traceability establishes a network of connections between diverse artifacts such as requirements, design, and code. However, given the cost and effort of creating and maintaining trace links manually, researchers have proposed automated approaches using information retrieval techniques. Current approaches focus almost entirely upon generating links between pairs of artifacts and have not leveraged the broader network of interconnected artifacts. In this paper we investigate the use of intermediate artifacts to enhance the accuracy of the generated trace links – focus- ing on paths consisting of source, target, and intermediate artifacts. We propose and evaluate combinations of techniques for computing …


Investigating Daily Fantasy Baseball: An Approach To Automated Lineup Generation, Ryan Smith Jun 2021

Investigating Daily Fantasy Baseball: An Approach To Automated Lineup Generation, Ryan Smith

Master's Theses

A recent trend among sports fans along both sides of the letterman jacket is that of Daily Fantasy Sports (DFS). The DFS industry has been under legal scrutiny recently, due to the view that daily sports data is too random to make its prediction skillful. Therefore, a common view is that it constitutes online gambling. This thesis proves that DFS, as it pertains to Baseball, is significantly more predictable than random chance, and thus does not constitute gambling.

We propose a system which generates daily lists of lineups for Fanduel Daily Fantasy Baseball contests. The system consists of two components: …

An Inclusive Design Approach To Integrating An External Human Machine Interface With Autonomous Vehicles, Sandra Roksic Jun 2021

An Inclusive Design Approach To Integrating An External Human Machine Interface With Autonomous Vehicles, Sandra Roksic

Master's Theses

As autonomous vehicles become more prevalent in urban traffic settings, the safety of vulnerable road users, predominantly pedestrians, must be placed in high regard relative to the design of the autonomous vehicle's (AV's) external human machine interface (HMI). Traditionally, there exist communication methods between drivers and pedestrians, such as hand gestures, eye contact, and verbal cues that convey the driver's awareness of the pedestrian's presence. However, with autonomous vehicles, there is a shift in communicative responsibility from the driver to the vehicle itself. It is the vehicle's responsibility to intuitively and clearly indicate its actions to the pedestrian.

This research …
