The City faces many of the same housing availability and affordability challenges as the rest of the State, but also has distinct characteristics that necessitate unique policies and strategies, such as the concurrent presence of both a large student and young professional population as well as a wealthy retirement community, which drastically drives up housing prices and demand.

The Flexible Density Program is proposed by the City of San …

Modeling The Spread Of Covid-19 Over Varied Contact Networks, Ryan L. Solorzano

Master's Theses

When attempting to mitigate the spread of an epidemic without the use of a vaccine, many measures may be made to dampen the spread of the disease such as physically distancing and wearing masks. The implementation of an effective test and quarantine strategy on a population has the potential to make a large impact on the spread of the disease as well. Testing and quarantining strategies become difficult when a portion of the population are asymptomatic spreaders of the disease. Additionally, a study has shown that randomly testing a portion of a population for asymptomatic individuals makes a small impact …

Examining The Ecological And Social Implications Of Parklets And Plazas Across Multiple Urban Scales, Joshua L. Muller

Master's Theses

Faced with population increases but stagnant capital improvements and impacts from global warming, cities around the world are experimenting with smaller-scale and cheaper strategies in order to accommodate the new influx of residents. New York City has led the way in converting low-efficiency intersection space into public plazas with a limited range of permanently installed elements and San Francisco has pioneered the concept of the parklet, which converts two to four street parking spaces into a modular and flexible pedestrian space. I seek to answer two questions about these spaces: What are common factors influencing the viability and successful implementation …

A System Dynamics Model Of Soil Carbon Stock And Flows In Grasslands Under Climate And Grazing Scenarios., Deirdre Sommerlad-Rogers

Master's Theses

Carbon sequestration is paramount to reducing climate change. Grasslands, representing 40% of all terrestrial area, can serve as a primary sequestration location if optimal management strategies can be realized. This study used system dynamics modeling to examine the temporal dynamics of carbon stocks and flows in response to grass species composition, grazing intensity, and temperature and precipitation changes at the landscape level. While there are other biogeochemical models in existence, they are either meant to model large areas, including globally, or are meant to be at a farm level and have limited plot sizes, limiting the options for rangeland managers …

An Artificial Neural Network For Bankruptcy Prediction, Walter D. Magdefrau

Master's Theses

Assessing the financial health of organizations remains a topic of great interest to economists, financial institutions, and invested stakeholders. For more than a century, research into financial distress has focused primarily on traditional applications of statistical analysis; however, modern advances in computational efficiency have created a significant opportunity for more sophisticated approaches. This thesis investigates the application of artificial intelligence on company bankruptcy prediction. The proposed neural network model is evaluated using the Polish Companies Bankruptcy dataset and yields a 5-year prediction accuracy of 96.5% and an AUC (area under receiver operating characteristic curve) measure of 92.4%.

Effects Of Compost On Soil Health And Greenhouse Gas Emissions: A Case Study In A Mediterranean Vineyard, Tsz Fai Wong

Master's Theses

Compost is commonly used as an organic amendment in cropping systems such as vineyards, and has been shown to be beneficial to carbon (C) sequestration and soil health. As perennial crops, grapevines have a larger potential for C sequestration than most crops. Yet, there is a lack of understanding regarding the relationship between compost application rate, the magnitude of C sequestration, and its environmental tradeoff in the form of greenhouse gas (GHG) emissions. In the study, we investigated the effects of compost application rate on soil C sequestration, GHG emissions, crop growth, and overall soil health after two annual compost …

A Performance Survey Of Text-Based Sentiment Analysis Methods For Automating Usability Evaluations, Kelsi Van Damme

Master's Theses

Usability testing, or user experience (UX) testing, is increasingly recognized as an important part of the user interface design process. However, evaluating usability tests can be expensive in terms of time and resources and can lack consistency between human evaluators. This makes automation an appealing expansion or alternative to conventional usability techniques.

Early usability automation focused on evaluating human behavior through quantitative metrics but the explosion of opinion mining and sentiment analysis applications in recent decades has led to exciting new possibilities for usability evaluation methods.

This paper presents a survey of modern, open-source sentiment analyzers’ usefulness in extracting and …

Investigating The Mechanism Of The Escherichia Coli Atp-Binding Cassette (Abc) Transporter Metni, Matthew Foronda

Master's Theses

Chemical homeostasis is a baseline requirement for any cell to survive. ATP-binding cassette (ABC) transporters play a vital role in homeostasis by importing nutrients and exporting toxins against their concentration gradients by utilizing the energy of ATP hydrolysis. Malfunctioning ABC transporters cause a variety of health problems, including cystic fibrosis, Stargardt’s disease (vision loss), and the development of drug-resistant tumors. An important step in solving these medical issues is to first understand the structure and mechanism of ABC transporters. Various studies have made great strides in depicting the structure and details of different ABC transporters and their mechanisms, however, many …

Envisioning Justice And Solidarity In The Household Workplace: The Organizing Power Of Immigrant Domestic Workers And Employers In The Bay Area, Nicole Laporte

Master's Theses

Domestic workers are skilled professionals who engage in a variety of activities ranging from housecleaning, elderly care and childcare support in private households. In the United States, it is estimated that there are over 2.5 million domestic workers, the majority of whom are immigrant women of color.[1] Due to the historic racialized and gendered exclusion from labor law protections such as the Fair Labor Standards Act of 1938, [2] the labor of domestic worker professionals has been made invisible in the United States. Today, domestic workers are three times as likely to be living in poverty and are less …

Lgbtq Forced Migrants' Labor Market Integration In Mexico City: Perspectives From Mexico's Government Agencies, International Organizations, And Mexican Civil Society, Rolando Diaz

Master's Theses

Mexico holds a unique position as a country of immigration, emigration, refuge, transit, and return migration. In recent decades, researchers have built awareness on the country’s received migrants’ diverse characteristics by posing questions and tackling the challenges that certain migrants face. Lesbian, Gay, Bisexual, Transgender, and Queer (LGBTQ) forced migrants have become increasingly visible since the exodus of asylum-seekers from Central America. Many of these LGBTQ migrants flee state and non-state actors that present life-threatening conditions for the LGBTQ community. Though Mexico as a whole is going through its own evolution on LGBTQ and migrants’ rights, its capital city has …

Hey Google: How Can We Build Critical Media Literacy?, Wilson Wang

Master's Theses

The year 2020 spotlighted problematic media coverage of the global coronavirus pandemic. Conflicting narratives of the origin of the “China virus” (Campbell & Park, 2020), the silenced journalistic freedoms (Davidson, 2020), and the impact on communities of color (Williams, 2021) created mass confusion during the global pandemic. To help address our understanding of media, teaching civic online reasoning (Wineburg & McGrew, 2017) and critical media literacy are two potential points of emphasis. Building critical media literacy helps resist the echo chamber effect of social media and cable news, which results in polarization and difficult mediation between parties (Bexley & Tchailoro, …

The Health Costs Of Political Identity: Evidence From Public Safety Responses In The Us And A Natural Experiment In California, Sahiba Chopra

Master's Theses

The Covid-19 pandemic has brought political polarization in the US to the forefront of the battle against coronavirus. We find that for every one percentage point increase in votes for Trump there are 881 more Covid-19 cases and 17 more Covid-19 deaths. We find that these results are motivated by political identity as it is mediated through public safety behaviors like maskwearing and social distancing. In addition, a natural experiment in California during the first half of the pandemic in the US finds that 36% of the Covid-19 cases at the census tract level in California can be associated with …

The Making Of Crimmigration: The Criminalization Of Immigrants, Dorisa Esparza

Master's Theses

For the past decades, immigrants and immigration policies in the United States of America are significant debates. During campaigns, politicians describe their immigration opinion and their immigration solutions. Media coverage also illustrates the fervor on immigration discourse. Immediately, one can argue that immigration discourse has extreme depictions of immigrants. Politicians use polarizing language that can be damaging for the immigrant community in the United States. The criminalization of immigrants was illustrated within the discourse and immigration policies.

This research will analyze the implication of immigration discourse from political actors on the creation of crimmigration policies. Crimmigration policies are defined as …

Attempting to address the lack of research on Pinay leaders in community- based organizations, this study will build on current Pinay epistemologies to further understand Pinay leadership. This study asks three research questions: 1) How do Pinays …

Transitioning Into Retirement: Effect Of Pension Expansion On Elderly Labor Force Participation In India, Devaprasad Sahadevan

Master's Theses

The welfare effects of public social security programs have been extensively studied in the context of developing economies where the reliance on state is much larger for the provision of basic goods and services. Pension schemes and reforms, however, are met with much less fiscal investment considering the demographic composition and the requisite demands of the larger proportion of youth- and working age- population. Given the rapid pace of demographic transition, there will inevitably be an ever-growing pressure and economic problems associated with aging are bound to become more apparent. As transitioning into retirement is an under-studied area in countries …

Police Union Membership And Lethal Use Of Force, Scott Barger

Master's Theses

I examine the Fraternal Order of Police union presence in cities as an explanation for the lethal use of violence. Using a novel dataset of FOP union presence, I utilize a simple log OLS linear model to explore the relationships between FOP unions and lethal use of force. I find robust evidence that FOP unions have higher incidences of death at the hands of police, compared to cities without a FOP union. Exposure to FOP leads to an increase in baseline risk of death by police by 17%. This effect increases for larger cities.

Alliance Building In The Food Sovereignty Movement: Perspectives From Activists Advocating For Farmworker Justice And Agrarian Justice, Sarah Ruszkowski

Master's Theses

The food sovereignty movement has come to encompass a wide-range of constituent groups, all with unique perspectives and interests. While some of these groups’ goals align naturally, others present priorities differently, namely organizations that advocate for farmworker justice and those that advocate for agrarian justice. Because of the power imbalance embedded in this relationship as well as the racist, patriarchal, and neoliberal nature of agrarian capitalism, it can be challenging to navigate an equitable path forward. In this thesis, I examine whether and how food sovereignty as a broader umbrella movement is generative towards building ties between advocates for farmworker …

The analysis …

Closing Down The Hall: San Francisco’S Efforts To Redefine Juvenile Justice, Madison Bliss Holland

Master's Theses

Significant research has demonstrated that juvenile prisons are obsolete for the following reasons: they fail to rehabilitate children and prevent future crime, they perpetuate pervasive abuse and trauma, they disproportionately target and further marginalize children of color, and the cost of youth incarceration has skyrocketed to unimaginable amounts. In light of all of these findings, in 2019, San Francisco became the first city in the nation to pass legislation to close its juvenile hall. In order to understand how this was possible and to understand its implications for other cities looking to engage in similar work, I asked the following …

The Inter-American Human Rights System In The Context Of Migration: Us Immigration Policies, Maira E. Delgado Laurens

Master's Theses

International human rights laws are critical to ensuring a minimum protection level for those migrating to other nations across the globe. Despite intense efforts by the United States to sidestep such policies while misrepresenting their repeated violations of human rights now taking place at the U.S.-Mexico border, these policies remain in full force in the global governance community. The actions of the Trump administration and others clearly indicate the need for political intervention to ensure such rights are maintained. Using qualitative content analysis and participatory observation, this article reviews the effectiveness of thematic hearings, under the Inter-American Commission on Human …

Do Letters And Gifts From International Sponsors Affect Child Outcomes? Evidence From Colombia, Ghana, And Haiti, Mai Moua

Master's Theses

Past research has found child sponsorship results in higher aspirations, mental health, and educational outcomes. In this research, I explore the extent to which these outcomes can be influenced by letters and gifts sent from the sponsor to the child. However, there is limited research on the effects of direct relationship between sponsor and child. Using 1142 sponsor letters and a 2017 survey from Compassion International, an international child sponsorship organization, we find that letters and gifts from sponsors have a statistically insignificant impact on outcomes including education, mental health, aspirations, social connectedness, nutrition, religiosity, hygiene, and views on drugs, …
