Goodworks: In Houston, A COVID-19 Storm
Get PDFMarlen Guerrero ’18, a Posse Scholar from Houston, Texas, began helping families long distance from Mayflower Hill after Hurricane Harvey hit her hometown. She continues that work, but recently saw her nonprofit pivot to address needs during the pandemic. She spoke with Colby Multimedia Producer Gabe Souza
Apparatus Improvement and Characterisation for Experiments on Ultra-cold Plasmas.
No full textApparatus for creating ultra-cold neutral plasmas (UNPs) was improved and data on plasma expansion was collected. We increase the trapping efficiency of a quadrupole magneto-optical trap (MOT) by installing a tapered amplifier to increase the power of the cooling laser used to trap atoms. We achieve an improvement in density of trapped atoms from 1 x 1010 cm-3 to 2.5 - 4.5 x 1010 cm-3. In addition, to improve precision and decrease systematic error, the magnetic field induced by inductive current in the MOT\u27s anti-helmholtz coils was suppressed. This was achieved by installing a KEPCO Bipolar Power Supply, which allowed for suppression of induced current to sub 200 microAmpere magnitudes during the experiment.
Expansion velocity of rubidium UNPs was studied using ion time of flight (TOF) spectra collected for plasmas with initial electron temperatures of 1-150 K and initial ion temperatures of \u3c100 microKelvin. We predicted a constant expansion velocity for a given initial electron temperature and our data generally agrees with this prediction well. However, for low initial electron temperatures and early in the plasma evolution we see a non-linear region. We suspect this is a result of the effects of three-body recombination. As such, we demonstrate that using ion TOF is a good way for studying spatial evolution of UNPs
El cruce de fronteras cinematográficas de Carlos Reygadas: la experiencia afectiva de Japón, Luz Silenciosa, y Post Tenebras Lux
No full textEl movimiento Nuevo Cine Mexicano de los años noventa marcó una nueva ola en la historia cinematográfica mexicana. Películas como Amores perros (Alejandro González Iñárritu, 2000), Y tu mamá también (Alfonso Cuarón, 2002), y Sexo, pudor, y lágrimas (Antonio Serrano, 1999), fueron dirigidas por algunos de los directores más reconocidos en México. Al mismo tiempo, Carlos Reygadas surgió en el mismo período, pero produjo películas que no podrían haber sido más diferentes a estas producciones, ya que el director empleaba actores no profesionales, filmaba en lugares rurales, y utilizó técnicas de slow cinema que crean una nueva experiencia fílmica. Sin los mismos medios de producción, sin símbolos nacionales o entretenimiento de ritmo rápido, ¿qué hace que las películas de Reygadas resuenen con audiencias más allá de la frontera mexicana? Argumento que en sus películas, lo que sientes tiene prioridad sobre lo que puedes racionalizar, lo que crea un modo universal de comprensión. A través de Japón (2002), Luz Silenciosa (2007), y Post Tenebras Lux (2012), exploro cuáles son esos sentimientos, o esos afectos, cómo se vinculan con el mundo natural, y cómo se alinean con las identidades marginadas. Afirmo que el afecto es la raíz de la transnacionalidad de las películas y examino las implicaciones de un medio visual que prioriza el sentimiento por encima de todo, tanto a escala local como global
Memories and New Beginnings: Chinese American Restaurants and Food as a Contact Zone in Early-Twentieth Century California
No full textIn previous Asian American studies, authors largely focus on urban centers. In my thesis, I center rural Chinese American communities in early-twentieth century California in the making of the Chinese American identity. I argue that they, along with Chinese American food, acted as contact zones for Chinese and non-Chinese Americans. This paper covers a range of themes, including most prominently the connection between food and culture. I additionally address how Chinese American restaurants and food challenged perceptions of Chinese Americans as foreigners, their role in gender relations, and what we consider to be authentic. This paper largely uses archival newspaper articles from the early-twentieth century to illustrate my argument. I aim to reposition rural Chinese Americans in California, in conjunction with their restaurants and food, as integral parts of the American story. Chinese American restaurants and food played a crucial role in creating the Chinese immigrant identity as Chinese and American
Municipal Reform in the Progressive Era: Spatial Spread and Fiscal Outcomes of the Commission Government
No full textThe Galveston-Des Moines Plan for commission government, seen as an important municipal reform during the Progressive Era meant to address corruption and inefficiency in many cities, was pitched by business elites and spread like wildfire in the 1910s. Is there a spatial component to the spread of the adoption of the commission form of government? What are the municipal fiscal outcomes of adoption? This paper shows that there was a spatial spread to its adoption using a lagged state adoption proportion variable. This paper also reveals that promises made by business elites such as increased efficiency and projects to improve infrastructure were not fulfilled under the commission model, with business elites seeming to benefit personally from its adoption. This is seen through a reduction in taxes that target corporate wealth
St. George’s Food Access Initiatives: Navigating Food Inequalities, Forging a Way to Food Choice Freedom, and Transgressing Culinary Borderlands in Lake County, Colorado
No full textAs guided by ethnographic fieldwork and the interdisciplinary discipline of Global Studies, this thesis works to trace food access inequalities in Lake County, Colorado and how they are felt and confronted both at the individual and communal level. Amidst the failures of global food systems and the ongoing impacts of the COVID-19 pandemic, rural communities, such as the field site of Lake County, Colorado, face additional challenges in accessing food that is culturally relevant, craved, and truly wanted. This thesis traces the dominant food inequalities in Lake County. In the face of these inequalities, I centralize the community food initiatives that take place at St. George Episcopal Church in Lake County. St George, as being both a space and a community, works to confront food inequalities through spearheading food initiatives within its sanctuary to make food more accessible for the greater Lake County community. As informed by ethnographic fieldwork in the setting of St. George Episcopal Church’s food initiatives, I consider and argue how St. George’s food initiatives create the opportunity 1) to name, place, and confront food inequalities, 2) offer individuals and the community opportunities to embolden their right to food choice freedom, and 3) provide a physical space to transgress culinary borderlands. This project draws on a vast literature of food studies to situate my research within. Ultimately this thesis serves, through sharing the story of what food can do and be at St. George, as an example of how tuning into a community’s needs can offer solutions to the shortcomings and failures of global food systems that are experienced individually and communally at the localized level
