Documenting Tetranychus Urticae And Lygus Hesperus Resistance Status In California Strawberries, Kiley William Jensen

Master's Theses

The resistance status of Tetranychus urticae Koch and Lygus hesperus Knight sourced from California strawberry fields was evaluated in laboratory bioassay experiments. Adult female T. urticae sourced from a miticide naïve population were exposed to a range of miticide active ingredient concentrations mixed with acetone in contact bioassay experiments. LC₅₀ concentrations for the active ingredients fenpyroximate, abamectin, bifenazate, and spiromesifen as well as LC₉₀ concentrations for the active ingredients fenpyroximate, abamectin, and bifenazate were derived from this susceptible population. A total of ten field populations of T. urticae, five from the Santa Maria growing region and five …

Master's Theses

Surveys of the four major soilborne pathogens of strawberry (Fusarium oxysporum f. sp. fragariae, Macrophomina phaseolina, Phytophthora spp., and Verticillium dahliae) to determine their relative prevalence were conducted in Watsonville-Salinas, CA in 2021 and in Santa Maria, CA in 2022. All four major pathogens were detected at relatively similar prevalence in Watsonville-Salinas, between 22% and 31% of sampled fields. In Santa Maria, M. phaseolina was far more prevalent at 52% of sampled fields, the other three falling between 14% and 17%. Additionally replicated greenhouse and field trials were conducted to evaluate the effects of wheat as …

Impact Of Long-Term Trauma Exposure On Competitiveness And Generosity, Anchal Khandelwal

Master's Theses

: Although half of all nations in the world have experienced armed conflict in the last 50 years, there is still a glaring lack of evidence on the persistent human costs of these conflicts. We exploit the quasi-random variation in abduction (Blattman and Annan 2009) and establish a control (neighboring) sub-county based on the intensity of exposure by the Lord’s Resistance Army in Northern Uganda to investigate the long-term impact of trauma exposure on competitiveness and generosity. We do this by conducting lab-in-field experiments on a sample of adult North Ugandan women and find that trauma exposure reduces competitiveness in …

The Right People In The Wrong System: Examining The Tension Between Nonprofit Individuals And Organizational Structure, Erin Vong

Master's Theses

Nonprofit organizations pursue missions of social good while still operating within the confines of systems of oppression, creating a tension between organizational values and operational success. Previous research focuses on the micro-level role of individuals and the macro-level role of ideologies that create these tensions for nonprofit workers in these spaces. Through a qualitative case study, this thesis seeks to uncover the meso-level role of organizational structures in the experiences of nonprofit workers. The research questions that guided this case study were (a) How does one organization present equitable working conditions for its staff? (b) How do staff at this …

Positive Out Of The Negative: Tracking Renewable Energy Projects In Central America, Jordan Ethan Castillo (Miner)

Master's Theses

Central America is undertaking a vast Renewable Energy (RE) transition, due to widespread investments across the region in an array of technologies. These technologies include Community Solar, Wind, and Hydroelectricity. Hydroelectricity has long been the backbone of many countries’ energy grids in the region due to the region’s long history with hydroelectricity. Ambitious climate goals coupled with diminishing hydroelectric power generation opportunities have led to an expansion of investment in Community Solar and Wind energy. The embrace of Solar and Wind has been accelerated due to declining costs for these technologies as they mature. Central America as a case study …

War And Genocide In Darfur And Its Impact On Darfur Society, Hamid Elshareif

Master's Theses

The Darfur region in western Sudan has witnessed bloody revolutions and conflicts since the beginning of 2003. The Sudanese government recruited militias such as Janjaweed who killed and robbed the civilian people of Darfur. The Janjaweed practiced murder, rape, torture, the burning of villages, looting, and theft which amounted to what most people consider genocide. This genocide is being practiced against the indigenous African tribes in the western region of Sudan which is less developed and has been marginalized by the government in Khartoum. Reasons for this conflict are in question with many people seeing it as purely an Arab …

Master's Theses

The purpose of the study was to determine how lay directors of works in Jesuits West secondary schools can be formed to best serve as faith leaders. The study consisted of secondary research in which interview data and surveys from studies on lay formation in Jesuit universities and lay leadership of Bay Area Catholic High Schools were used to determine whether or not formation of lay directors of works in faith leadership is possible, what the objectives of that training should be, and how that training can be offered. This analysis determined that lay formation is both possible and necessary. …

Mapping Effectiveness: Farm Mechanization Initiatives By Lumbini Province Of Nepal (Fiscal Year 2018/19), Ananda Phuyal

Master's Theses

An effective farm mechanization program should increase crop production and be profitable to the benefitting households. Increasing labor shortages and decreasing animal draft power in agriculture demanded farm mechanization to increase food productivity in Nepal. To increase crop yield, the Ministry of Land Management, Agriculture and Cooperative (MOLMAC) of Lumbini Province in Nepal distributed 1994 subsidized tools and machinery in Fiscal Year 2018. The farm mechanization program by the government was an ambitious program and was implemented without research to address the actual need of the geography. However, the program had a positive impact on the community. It is found …

Unaccompanied Migrant Children And Adolescents’ Rights In Colombia: Between Invisibility And Incapacity, Linda María Urueña Mariño

Master's Theses

This thesis centers on an analysis of the situation of unaccompanied migrant children and adolescents transiting through and settling in Colombia, from a children’s rights perspective. These children are being invisibilized, which is causing their unprotection and multiple violations of their rights. Through a critical policy analysis, with a review of Colombian migration and child protection policies, and interviews with governmental and nongovernmental representatives working with migrant children in the country, the study aimed at contrasting policies with the real practices of migrant children protection.

The analysis recurred to Bauman, Butler, Crenshaw, among other authors to show how the Colombian …

Preparing To Engage Migrant-Origin Students Through Culturally Responsive Teaching: A Handbook For Teachers, Grayson E. Briggs

Master's Theses

Students of migrant-origin currently represent approximately 25% of the total student population in the United States. As immigration to the U.S. continues, the proportion of migrant-origin students in public schools is only expected to grow. Despite the growing representation of migrant-origin youth amongst the K-12 student population, current schooling approaches have not expanded to address the diversifying needs of the student population. Because public school systems are struggling to adapt to the needs of migrant-origin students, these students’ educational attainment is suffering. The presence of implicit bias, microaggressions, and stereotypes in all aspects of schooling is a significant factor that …

Restorative Justice: How Adult Practitioners Navigate Contested Learning Environments, Andrés Castañeda

Master's Theses

Restorative justice principles and practices have gained significant traction among educators in recent years, as they endeavor to establish school cultures that prioritize safety, student belonging, and humanizing relationships. However, existing literature indicates that schools who implement restorative justice frameworks tend to be obstructed by the historically punitive logics that govern them. As schools have become institutions that are highly racialized and influenced by neoliberal policies, it is important to continue to identify factors that can impede the work of racial equity and social justice within the schooling system. The purpose of this thesis is to conduct a qualitative study …

Between Life And Death: Reimagining Black Reproductive Healthcare, Briana Britton

Master's Theses

The state of Black reproductive health is in crisis with mortality rates of birthing people in the U.S. being the worst in the developed world. What compounds this issue is historical and cultural evidence of unethical and inhumane treatment of Black people – Black birthing people in particular – by the U.S. healthcare system primarily due to racism and sexism. Those who do not identify with the binary and heteronormative structures of our healthcare system are at further risk of discrimination and health disparities. Due to social and cultural ideals, stigma, and other structural forces, Black, Black birthing and Black …

“An Untold Story”: Voices Of Qtbipoc Individuals Who Have Been Canceled Through Public Call Outs, Glorivette Rodriguez

Master's Theses

QTBIPOC communities are historically marginalized groups that experience oppression and discrimination. Oftentimes, this experience goes unnoticed, unacknowledged, and unrecognized because these groups are intentionally erased and silenced by dominant culture. Keeping the communities safe is a priority, and it is no wonder that social media is being used as a “necessary survival technology” (brown, 2020, p. 45) to call out injustices and harm. Unfortunately, communities are unskilled in navigating conflict using a transformative justice approach and thus, used this tool unskillfully, which has been referred to as “knee-jerk callouts” (brown, 2020, p. 40). This study explores the experiences and impacts …

Feeling Status: What Emotion Reveals About Immigrant Relationships With The United States, Faith Johanna Williams

Master's Theses

Traditional understandings of legal status focus on its role as a mechanism for state function without adequately acknowledging the emotional component of how it feels to navigate it, especially for immigrants. Drawing on the embodied wisdom of immigrants to better understand what legal status is and what role it plays in society, this study utilizes 13 semi-structured interviews conducted with immigrants now permanently documented in the United States as legal permanent residents or naturalized citizens, who previously lived undocumented in the country, to identify several patterns that highlight the limit of conventional notions of citizenship. By employing a person-centered approach …

Calladitas No Nos Vemos Más Bonitas: Testimonios Of Mexican Migrant Catholic Mothers’ Resistance To Marianismo, Jessica Guadalupe Ornelas

Master's Theses

The purposeful killing of women due to their gender (feminicide) is an atrocious global act that has been ascending at an alarming rate, over the past couple of years. Specifically, last year in México and in the duration of six months, there were close to 3,000 victims of gender based killings in México, which is about 10 casualties daily (ONU Mujeres, 2022). While most studies have centered their attention on systemic causes that lead to gender based violence, the amount of research that closely analyzes the ways these causes are interwoven with womens’ everyday lived experiences of social and personal …

Invisibility: Bringing Statelessness To The Forefront Of U.S. Political Advocacy, Claire G. Green

Master's Theses

Currently, an estimated 218,000 stateless persons are living in the United States. With no legal structure specifically addressing statelessness, stateless persons are left in a perpetual state of legal ambiguity. This project explores current research on statelessness in the United States, examines general awareness and attitudes towards the stateless population, and seeks to further understand how to increase empathy and engagement in the push for stateless rights. Guided by the lens of feminist political theory, I attempt to answer the following research question: Can autobiographical works of art be utilized as healing tools of empowerment and catalysts for political recognition …

Cost-A-Lot Of Evictions And Displacement: Meda's Role In Community Organizing And The Impacts Of The Costa-Hawkins And Ellis Acts, Henna Gandhi

Master's Theses

In February 1995, the Costa-Hawkins Rental Housing Act (AB1164) was passed in California. Developed by two Democratic state policymakers, Senator Jim Costa and Assemblymember Phil Hawkins, the act encompassed both Senate Bill 1257 and Assembly Bill 1169 (Goldberg 2, 2018). The Costa-Hawkins Act was a vacancy decontrol legislation that overruled strict rent control measures in cities across California. In combination with rent control and Costa-Hawkins, the passage of the Ellis Act (1985) by state legislators further contributed to the affordable housing crisis. With the current affordable housing crisis, I turn to community- based organizations (CBOs) who provide housing solutions for …

Charity Begins At Home: Investigating How Culture Shapes In-Group Bias In Altruistic Behavior, Angira Shukla

Master's Theses

The paper builds a structural model of altruistic transfers based on identity matches with another individual and estimates the weights that people place on the characteristic matches. We also take a comparative look at the role of culture in these transfers. The culture here is trying to contrast a traditional society versus a cosmopolitan one. I run an experiment in India to examine these differences. I find that in both the urban and rural samples individuals tend to give more to girls and donate largely on the basis of the need of the receiver. I also find that the rural …

Political Economy Of General Normative Force In The Paris Agreement, Jonah B. Jellesed

Master's Theses

The Paris Agreement revolutionizes international cooperation in addressing the urgent threat of climate change. However, its status as an emerging system of global climate governance remains largely unexplored. Drawing on HLA Hart's legal theory, we apply a straightforward test to determine its significance, revealing the Paris Agreement as evidence of a new international legal order. This has far-reaching implications, particularly in the realm of political economy. Unlike previous analyses that merely consider whether a state is a signatory to the agreement or not, our innovative approach delves deeper into countries' commitment. Our analysis shows high compliance levels among populations in …

Tempers Rising: The Effect Of Heat On Spite, Jake C. Cosgrove

Master's Theses

The relationship between heat and harmful outcomes is well documented, with research connecting various adverse economic outcomes to the climate. In the presence of increasing global warming and climate change, understanding why the climate leads to negative economic outcomes is essential for forming peaceful institutions of the future. We study how behavioral economic outcomes change in the presence of heat through a lab experiment involving 1,110 observations conducted in five different countries. This paper specifically focuses on the social preference outcome of spite. We find that increased time exposure to the treatment effect of heat is required to elicit an …

Empirical Evidence For The Emergence Of Global General Normative Force In The Paris Agreement, Michael J. Nordquist

Master's Theses

The Paris Agreement presents a unique framework to address the pressing dangers of climate change. Given the magnitude of this global problem and our reliance on international treaties to counteract its adverse effects, it is imperative that we understand the evolving norms within this domain. To evaluate the extent to which the Paris Agreement serves as a second-order "rule of recognition" in the context of global climate governance, we utilize a straightforward test rooted in Hart's theory of the rule of law. Our approach entails enumerating the number of countries worldwide that have enacted laws explicitly referencing the Paris Agreement, …

The Labor And Educational Effects Of Daca: Evidence From California, Oscar A. Alonso Guerra

Master's Theses

The Deferred Action for Childhood Arrivals (DACA) program, implemented in 2012, has been a subject of intense debate. While much research has examined the early effects of DACA, this study contributes to the literature by analyzing more recent data on the labor and educational outcomes of DACA recipients in California. Using a difference-in-differences approach, I aim to uncover significant changes in the labor market and educational outcomes of DACA recipients over time. I find those eligible for DACA experienced noteworthy effects compared to those who were ineligible. Specifically, they exhibit a significant 3.1 percentage point increase in the likelihood of …

The purpose of this project is to further understand the implementation of the second provision of the Real ID Act of 2005 which issues marked identifications and driver's licenses that are federal compliant and understand how it will affect Latino undocumented California residents. The focus of this study through the literature review and the Testimonios is on the experiences of Latino undocumented immigrants living in California, and is viewed through a Latino Critical …

Sweet And Timely Insurance: The Role Of Honey In Reducing Coffee Producer Food Insecurity Exposure In Mexico, Grant Xavier Storer

Master's Theses

Smallholder coffee producers face a combination of pre- and post-harvest risk factors that leaves them particularly vulnerable to food insecurity. A popular form of on-farm diversification is honey production through beekeeping, that has both nutritional and commercial value. This study investigates the role of honey production as means of food security management due to the heightened pollinating activity during the coffee flowering stage that follows the annual coffee harvest provides an additional non-contemporaneous source of income. Using primary data collected in coffee-producing regions of Chiapas, Mexico, I find that during the honey harvest months, which occurs during the early stage …

By examining the historical, cultural, and economic contexts of meat consumption in Norway as well as the environmental impacts and ethical considerations associated with meat production and consumption, this thesis seeks to provide a nuanced understanding of the drivers of meat consumption in Norway. Following a brief outline of how these issues are to …

Silent Weapon: A Documentary On Ending Police Corruption In Nigeria With A Nonviolent Social Movement, Damilola Adesanya

Master's Theses

This documentary aims to examine the issue of police corruption in Nigeria and see how a nonviolent movement can be implemented to end this problem. The focus is on nonviolent movements like the #ENDSARS was used to bring change where there seemed to be no hope. There have been many accounts of the experiences of the citizens of Nigeria when it comes to police corruption. Unfortunately, a lot of these situations have gone untold. Some Nigerians believe there is no way to stop the police from being corrupt, as it has been going on for too long. Many citizens feel …

The Grid That Binds: The Renewable Energy Transition In Germany, France, And Italy, Katherine A. Mason

Master's Theses

The current energy crisis and climate change are just some of the challenges that the European Union and its member states are forced to reckon with. The loss of fossil fuel supplies from Russia in the wake of the invasion of Ukraine forced the acceleration of the renewable energy transition and created a new set of problems to be addressed, namely the effectiveness of climate work that had already begun, and what the roadmap for the future would look like. Examining the history and infrastructure of Germany, France, and Italy presents insights into how this challenge can be met, and …

Abolition Ecologies And The Making Of Freedom As A Place In Bayview-Hunters Point, Spencer Daniel O'Hara

Master's Theses

In this paper, I critically explore the subjectivities of Hunters Point Naval Shipyard (HPNS), part of the largest redevelopment project in San Francisco since 1906. Applying an abolition ecologies framework, I ask what explains the duplicity of the Shipyard as a site of radioactive contamination and capital accumulation, and in the same time-space one that creates the conditions for radical place-making. Hunters Point Naval Shipyard is a former commercial and military shipyard located on a peninsula in southeastern San Francisco. Motivated by its desire for a major shipbuilding and repair facility to project maritime power in the Pacific, the Navy …

Liberté, Égalité, Identité: Media And The Construction Of French National Identity, Hannah D. Lahey

Master's Theses

In 2015, France was rocked by a series of terror attacks that seemed to act as a tipping point for the fears and tensions that had been brewing in Europe in the months leading up to the strike. These attacks, and the subsequent responses to them, point to the influence of a much longer history of French involvement in the Middle East, and the lasting impact that colonization has on French national identity formation. With the creation of French national identity, and therefore the creation of the group that is deemed necessarily outside of this identity, the moral values and …

The Central American Minors Program: Advocating For Private Sponsorship, Magaly Velasco-Escobar

Master's Theses

Under this recommendation, minors would be interviewed by qualified officers at resettlement agencies in their home countries to assess credible fear, those deemed eligible but lacking an eligible relative would be referred for a private sponsorship pathway. Sponsors would be vetted and qualified using protocols currently in place by the Welcome Corps and Refugee Foster Care. Ideally, the Office of Refugee Resettlement (ORR) would coordinate between the private sponsors and overseas resettlement agencies, given they already do the work of vetting eligible sponsors for minors. ORR could create a program staffed with qualified individuals to coordinate this program or provide …
