Mutual benefits of inducible defenses to crab predators in the blue mussel Mytilus edulis in a multi-predator environment
Date: 2021-01-01
Creator: Sophia Walton
Access: Open access
- The blue mussel Mytilus edulis alters its phenotype in species-specific ways in response to either green crab (Carcinus maenus) or sea star (Asterias sp.) predation. Previous studies have shown that only sea stars induce changes in abductor muscle morphology, while green crabs generally alter the shape and thickness of shells. In the Western Gulf of Maine, Blue mussels collected from wave protected sites with abundant green crab predators were shown to have significantly thicker shells and larger adductor muscles than mussels collected from wave exposed sites with few green crab predators. The phenotypes of mussels originating from wave-protected and high green crab abundance sites increased the handling time by A. forbesi compared to sites with low wave exposure and high green crab abundance. These results contradict the paradigm that shell thickness trades off with abductor morphology, and I propose that a likely candidate for increased energy allocation to these traits is a decrease in reproductive allocation. My results further suggest that the escalating “arms race” between invasive green crabs and blue mussels in the Western Gulf of Maine is leading to changes in the phenotypic response of mussel populations in ways that are likely impacting sea star foraging dynamics.

Minor, Ugly, and Meta: Feelings in Contemporary Korean American Literature
Date: 2022-01-01
Creator: Kyubin Kim
Access: Open access
- In 2019, Korean American writer Cathy Park Hong published her memoir Minor Feelings: An Asian American Reckoning in the midst of a turning point in Asian American politics. Hong describes minor feelings as “emotions that are negative, dysphoric, and therefore untelegenic, built from the sediments of everyday racial experience and the irritant of having one’s perception of reality constantly questioned or dismissed.” Used as a concept to summate the Asian American experience in white America as living in a country where one’s reality is constantly questioned and made invisible, minor feelings forges an affective framework to study minoritized, diasporic literature. My project enriches Hong’s “minor feelings” by studying Korean American literature through a transnational and multimedia lens, considering how Korea’s colonial history and nation-building play roles in emoting Korean American self-realities. I structurally model my project after Sianne Ngai’s Ugly Feelings, split into four chapters, each focusing on one affect: shame, anger, han, and love. My project follows and documents the contemporary shifts occurring in Korean Americana, in how they perceive collective racial and diasporic identity, the intersectionality of layered identities, and the younger generations’ call for coalition. Since Korean American affects often are studied as an afterthought to Korean affects, my project retains a focus on the Korean American experience, recentering members of a diaspora whose globalizing homeland’s triumphs may eclipse their minor, invisible realities in America.
Nuevas posibilidades para la subjetividad feminista en la literatura del Cono Sur
Date: 2022-01-01
Creator: Kate Elizabeth Tapscott
Access: Open access
- ¿Cómo es que se puede escapar verdaderamente de la opresión patriarcal? Esta investigación aborda a través de un análisis de la literatura de escritoras del Cono Sur el asunto complicado de la liberación bajo un sistema en constante mutación. En el primer capítulo, a partir de aportes teóricos de Freud, Josefina Ludmer y Homi Bhabha entre otros, analizo cuentos de Jorge Luis Borges, Silvina Ocampo, y Clarice Lispector cuyas protagonistas intentan resistir su condición de víctima con diversos grados de éxito. En el capítulo que sigue, exploro una tendencia reciente en la literatura de escritoras del Cono Sur que incorpora elementos del horror y lo gótico para desestabilizar una cosmovisión humanista y patriarcal. Incorporando la teoría de Gabriel Giorgi, Rosi Braidotti, y Julieta Yelin, investigo los efectos que los animales, los cuerpos, y la materia tienen en la expansión de la agencia feminista y discuto si ofrecen o no nuevas e inesperadas posibilidades para resistir el sistema.

A Comprehensive Survey on Functional Approximation
Date: 2022-01-01
Creator: Yucheng Hua
Access: Open access
- The theory of functional approximation has numerous applications in sciences and industry. This thesis focuses on the possible approaches to approximate a continuous function on a compact subset of R2 using a variety of constructions. The results are presented from the following four general topics: polynomials, Fourier series, wavelets, and neural networks. Approximation with polynomials on subsets of R leads to the discussion of the Stone-Weierstrass theorem. Convergence of Fourier series is characterized on the unit circle. Wavelets are introduced following the Fourier transform, and their construction as well as ability to approximate functions in L2(R) is discussed. At the end, the universal approximation theorem for artificial neural networks is presented, and the function representation and approximation with single- and multilayer neural networks on R2 is constructed.
The Price of Carbon: Politics and Equity of Carbon Taxes in the Middle Income Countries of South Africa and Mexico
Date: 2015-05-01
Creator: Bridgett C McCoy
Access: Open access
- This study provides the first analysis of the politics and ethics behind carbon taxation in South Africa and Mexico. Using the preexisting scholarly frameworks of climate change policy, tax policy, and Robert Putnam’s two level games, I determine that in both cases, international pressures from multilateral negotiations and international development funding sources initiated the carbon tax policymaking process within the environment and treasury ministries of both countries. Once environment ministry bureaucrats initiated the carbon tax a lack of politicization of climate change (both countries) and an additional gain of raising revenue (Mexico) allowed the taxes to become law. I then turn to the laws themselves, analyzing their implications for climate justice. In both cases, the government did not adopt any proposals made interest groups representing environmental concerns and poverty groups, and instead shaped the bills so as to tailor to the interests of heavy manufacturing. This policy decision had the main effect of weakening the climate change mitigation impact of the carbon tax, and exacerbating issues of regressivity by not recycling revenues towards projects aimed at poverty reductions. I conclude this paper with an analysis of the ethics of such a carbon tax in developing countries. The carbon taxes, as they currently exist, sacrifice the rights and needs of the present poor for those of the future generation while an ideal policy that addresses poverty betters the condition of both groups. In order to ensure climate justice and for all groups and prevent political backlash, policy makers in middle-income countries must make carbon reduction policies with the unique challenges of poverty and climate change mitigation in mind.
