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.
Seeking shear waves in liquids with picosecond ultrasonics

- Picosecond shear acoustic pulses can be generated in solids using ultrashort optical pulses. Here we use this technique to seek high frequency shear waves in water, ethylene glycol and glycerol while simultaneously measuring high frequency longitudinal wave velocity and attenuation. We use a silica thin film on (114) GaAs to generate shear and longitudinal acoustic pulses at frequencies up to ∼50 GHz by ultrashort pulsed optical excitation. The acoustic pulses are transmitted into adjacent liquids, and are detected through variations in the optical reflectivity. Although we could not detect shear waves in these liquids, we did detect gigahertz longitudinal elastic stiffening. © 2007 IOP Publishing Ltd.
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.
