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.

Building Home in Diaspora: New York’s Jewish Left and the History of the Bronx Housing Cooperatives

Date: 2022-01-01

Creator: Micah Benjamin Wilson

Access: Open access

This thesis investigates three predominantly Jewish housing cooperatives that emerged in the Bronx in the late 1920s. The Amalgamated Housing Cooperative, the United Workers Cooperative Colony (the “Coops”), and the Sholem Aleichem Houses offered garment workers utopian retreats from the drudgery of Lower East Side tenements where Jewish immigrants arrived in droves between 1890-1920. With each cooperative housing a distinct faction of the Jewish Left––from socialists to communists to Yiddish nationalists––the Bronx housing cooperatives, more than experiments in communal living, were the site of a highly contested battle over competing Jewish cultural and political worldviews across the 1930s and 1940s. Transcending the era that is typically considered the movement’s “peak” in the 1910s, this thesis demonstrates that the era of the Bronx cooperatives must be central to any study of the Jewish labor movement by revealing the ways radical Jews attempted to maintain and negotiate their various worldviews against the backdrop of the threats posed by the capitalist housing market, assimilation, and sectarian struggles. I reconsider the disproportionate attention the “success story” of the Amalgamated Cooperative has received, situating its politics as but one of many responses to the contradictions embedded in the housing cooperative model. Finally, I analyze the role of nostalgia present across resident recollections of the cooperatives and situate it in the contexts of 1970s neoliberal urban reform and suburbanization, while considering the discursive power of this emotion to obscure the persistent legacy of anti-black racism entangled in the cooperative housing movement despite its progressive reputation.
