Online 72. "A Different Kettle of Fish": OPEC's Impact on Oil Nationalization, Political Accountability, and Governance [2024]
- Nicolson, Bailey (Author)
- May 15, 2024; May 15, 2024; May 15, 2024
- Description
- Book
- Summary
-
Academic literature and scholarship surrounding the Organization of the Petroleum Exporting Countries (OPEC) and the effects of oil nationalization evaluate the two separately. Econometric analyses debate OPEC’s ability to control prices according to dominant cartel theory and question OPEC’s relevance economically (Rose 2004). Studies of the effects of natural resource nationalization emphasize the regional effects, without considering the socio-political effects of OPEC membership. My research bridges this gap by asking: for countries with nationalized oil programs, how has membership in OPEC affected political accountability? OPEC membership for countries with nationalized oil programs may provide the collateral for resource-rich countries to bargain for their own oil interests and profit. In my thesis, I evaluate two pairs of countries which nationalized their oil industries; in each pair, one country joined OPEC, whereas the other did not. One pair, Nigeria and Bolivia, represent countries with conflict that preceded nationalization; the other pair, Argentina and Iran, represent two countries that nationalized in the 1950s. I compare both sets of cases’ political accountability before and after oil nationalization and also relative to dates the country joined OPEC. I utilize primary and secondary materials, including historical accounts, interviews, and various archives to understand the trajectory of a country before nationalizing their oil program and the implications of the nationalization event on political accountability. My thesis draws on sources from the UK National Archives in Kew, England, the Lyndon B Johnson Presidential Library in Austin, Texas, and the Hoover Library in Stanford, California. This archival research contextualizes the relevance of sovereignty over natural resources and contemporary debates surrounding the impact of OPEC for global petroleum markets. I find that countries that joined OPEC have fewer institutions of political accountability than countries that never joined OPEC. I also present possible explanations for this finding, including that countries that nationalized and never joined OPEC did so due to domestic political pressure, which solidified channels of political accountability. Countries that did join OPEC nationalized their oil reserves due pressure from international interests, and did not create or support methods of political accountability in the process.

Online 73. A Drone Based Wildfire Monitoring System [2024]
- Danish, Mohammed (Author)
- May 10, 2024; 2024
- Description
- Book
- Summary
-
Wildfires pose significant challenges to global communities, affecting lives, property, and the environment. In response to the increasing frequency and intensity of wildfires, particularly in Sweden and California, this report comprehensively explores a drone-based wildfire monitoring system developed by students from Stanford University and Linköping University, sponsored by SAAB. This system, designed to enhance real-time situational awareness and improve decision-making for wildfire management teams, includes an innovative air and ground unit structure to assist firefighters in their operations. Integrating an air and ground unit enhances situational awareness with accurate fire spread data through real-time thermal imaging and predictive mapping. The air unit features lightweight construction with four propellers and various sensors like IR imaging cameras and GPS, while the ground unit displays intuitive real-time data. The project aims to improve communication and predictive analytics, ultimately empowering firefighters with crucial data to make informed decisions and enhance wildfire management strategies.

Online 74. A Kinetic Inductance Parametric Amplifier for Quantum Sensing [2024]
- Rosenfeld, Ethan (Author)
- June 9, 2024; June 2024
- Description
- Book
- Summary
-
Superconducting parametric amplifiers are used extensively to amplify signals in sensitive cryogenic measurements of quantum devices. State-of-the-art Josephson parametric amplifiers have a 1 dB compression point limited by higher order nonlinear processes at large gain and are currently incompatible with frequencies in the millimeter-wave band (30-300 GHz). In this work, we present a resonant parametric amplifier using four-wave mixing based on nonlinear kinetic inductance in thin film NbTiN. The device is engineered with coupled transmission lines to reduce added noise by placing the pump tones at adjacent modes to the signal tone. This device is designed with an eye towards future quantum sensing applications—in particular towards the preparation of squeezed millimeter-wave photons for use in impedance microscopy of 2D materials beyond the standard quantum limit.

Online 75. A Logical Theory of Analogy via Common Abstraction [2024]
- Nakas, Filippos (Author)
- June 4, 2024; [ca. 2023]
- Description
- Book
- Summary
-
In this thesis, we present a formal theory of analogical reasoning that aims to define the class of deductive analogies which depend on abstraction and prove some important properties about them. Although analogical reasoning is usually viewed as an inherently probabilistic or heuristic form of inference, we focus on a class of analogies that are deductive. To do this, we attempt to generalize the theory of analogy via determination of Davies and Russel, which, as far as we know, is the only theory that has managed to give an account of deductive analogy. We first show why plain determination relations cannot adequately describe a sub-class of deductive analogies that are grounded on the existence of something like a determination relation for a higher level of abstraction than that at which the source and target domain are described. We solve this problem by formulating a theory of, what we call, common functional abstractions between different domains, which gives a potential formalization of the notion of common abstractions introduced by Genesereth, and show how these abstractions can viewed as expressing abstract determination relations. The theory we introduce allows us to naturally describe hierarchies of such abstractions which provides a means of formally comparing the quality of different analogies for the same problem, which, as far as we know, has not been previously achieved for deductive analogies. For a set of candidate analogies, we define the best one as that which uses the most concrete common abstraction between source and target, and prove that, if the set of candidates is unique, the best solution is discoverable and unique. Finally, we extend the theory of analogy via common abstraction to take account of cases where the initial descriptions of source and target should be somehow reinterpreted before the best analogy between them can be determined. We formalize the intuitive notion of ”re-interpretation” using the pair of relations specialization/generalization which, in our formalism, is orthogonal to the pair concretion/abstraction. In this extension of the theory, we can still define the best analogy as that which relies on the set of the least specific versions of the unique most concrete common abstraction.

Online 76. A Pathway to Protection [2024]
- Walley, Arabella (Author)
- July 1, 2024; July 1, 2024
- Description
- Book
- Summary
-
For her capstone project, Arabella Walley created a short documentary film shedding light on the U-Visa application process for immigrant women in the Bay Area. Arabella examines how the U-Visa, a legal visa available to undocumented immigrants who have been victims of crimes on U.S. soil, has both risks and benefits for applicants. This documentary highlights the specific challenges faced by applicants such as long processing times, privacy concerns, and victim re-traumatization. By tackling this timely immigration issue, Arabella hopes to bring further awareness about the social and legal services needed to assist and guide U-Visa applicants in their pathway to legal status and, eventually, citizenship.

Online 77. A Social Network Analysis of the Feminist Sex Wars [2024]
- Ruedas, Andrea (Author)
- April 3, 2024
- Description
- Book
- Summary
-
During second-wave feminism, gender, sex, and sexuality emerged as popular topics in a debate questioning the place and implications of sex through a feminist lens that eventually became known as the “sex wars.” Two dominating theoretical camps emerged: anti-porn versus sexpositivity. Anti-porn feminist scholars claimed pornography was the modern root of genderbased violence, gender oppression, and male domination; as such, all pornography contributed to hierarchies of power which placed women at the bottom and scholars contended that it did not deserve to exist and much less be legalized by national institutions. Sex-positive scholars responded by nuancing the identity politics employed by sex-negative feminists; they interpreted sex, especially queer sexualities, as existing in direct opposition to patriarchal and heterosexual impositions on bodily and sexual autonomy. However, the sex wars continue to be predominantly portrayed as a dichotomous and monolithic debate in feminist studies without regard for its many participants who vigorously contributed over the years and for the impact it had at all analytical levels in both social and political science. In an attempt to provide a more holistic representation of the sex wars, I collected data on feminist scholars’ co-authorships throughout the three most recent waves of feminism and constructed a visual network of their ties. I followed by analyzing the emergent themes depending on the scholars’ camp in order to understand the shift in feminist contribution to the sex wars over time. The following is a network analysis of feminist theory authors’ collaborations which examines the shifts in the sex wars discourse according to the past three feminist waves.

Online 78. A Tavola con la Famiglia: The Family Meal, Body Image, and Eating Disorders among Italian Adolescent Females [2024]
- Zarrow, Rachel (Author)
- March 27, 2024
- Description
- Book
- Summary
-
Although M.F.K. Fisher may have meant this in a literal, chronological sense, implying that eating should be the first task at the table, recent research shows that sitting down for a meal should be a family's first priority for health reasons. Studies have linked the family meal with nutritional benefits for adolescents, such as increased intake of healthy foods (Fulkerson, Neumark-Sztainer, and Story 2006; Hammons and Fiese 2011; Videon and Manning 2003). Research also shows that it is not just the food consumed during family meals that impacts adolescents' health but also something in the ritual itself. For adolescents, family meals have been inversely correlated with risky behaviors including eating disorders (Hammons and Feise 2011). One of the few existing crossnational studies of family meal behavior compared family meal frequency across 31 countries for fifteen-year-old students. Of students from all 31 groups, the American respondents reported the second lowest frequency of family meals. Conversely, the respondents who reported the highest frequency of family meals were those in Italy (Davidson and Hauthier 2010). The famous Italian proverb, "a tavola non s'invecchia, 11 translates to, "at the table, one doesn't age." This adage implies that mealtimes are a sacred time and they remain central to Italian family life. Sociologically, the food culture in Italy appears to differ from that found in the United States. While the US has experienced an increase in the number of fast food establishments, Italy has retained its rich food-oriented culture despite industrialization. Unlike in the United States, economic growth in Italy did not lead to considerable increases in fast food consumption and home cooking still remains a significant part of Italian culture (Capatti and Montanari 2003). This pilot study attempts to examine if the pattern found among adolescents in the US--an inverse correlation between family meal frequency and cases of eating disorders-- is the same in Italy. It aims to identify potential protective factors that mitigate disordered eating in Italy with the goal of informing public health approaches for the prevention and treatment of eating disorders in Italy and in the United States. This study attempts to answer the following question: Is there a relationship between rates of disordered eating and family meal frequency and patterns in Italy?

Online 80. a_blurred_fluxx_00.avi: Blackqueer Self-Becoming through Lo-Fi and D-I-Y Aesthetics [2024]
- Osawemwenze, Osadolor (Author)
- June 7, 2024; May 10, 2024
- Description
- Book
- Summary
-
Lo-Fi and D-I-Y aesthetics, especially in audiovisual productions, I argue throughout this thesis, can be an Afropresentist tool for Blackqueer folks to reimagine their sense of self, community, and relationship with their cultural memory, the everyday present, and envisioning the future. Lo-Fi and D-I-Y's audiovisual aesthetic provides Blackqueer folks the agency to reveal and remain pixelated, shaky, blurry, inaudible, elusive, and abstract in their endless process of self-becoming. The film, 'MOSQUITO: The Movie' (2022), and the album, Uncloseted (2002), are, respectively, the visual and sonic case studies of my content analysis that help reframe the expansiveness of Blackqueer diasporic experiences, development, and understanding of space and time. I engage with Nigeria's cinematic world of Nollywood as a nexus point to move discussions around definitions and implications of Lo-Fi and D-I-Y aesthetics beyond the Western contextualization of media. I draw from academic and non-academic thought around Afropresentism, glitch feminism, queer futurity, the queer art of failure, the Black ratchet imagination, Black interiority, and more to create a synthesis of knowledge around the beautiful complexities of Blackqueerness that also continues to help me see the utopian potentials in mine. I made a short film entitled a_blurred_fluxx_00.avi as an artistic rendering of this thesis paper, personifying the research sonically and visually.
