Lost Ground: Neoliberalism, Charter Schools, and the End of Desegregation in St. Louis, Missouri

During the final decades of the twentieth century, U.S. urban education policy experienced a sea change in its orientation toward equity. Mid-century social liberalism and its programs for expanding access to public education resources through desegregation and more equitable funding gave way to neoliberal reforms focused on improving outcomes through deregulation, accountability regimes, and market discipline. Charter schools are the vanguard of neoliberal education reform. While much of the research on charters aims at either substantiating or critiquing their success claims relative to traditional public schools, in this dissertation, I examine the role of charter schools within the larger processes of urbanization. Specifically, I focus on St. Louis, Missouri, where, in 1998, a single piece of education reform legislation (Senate Bill 781) legalized charter schools and set an end for the largest and longest-running school desegregation program in U.S. history. Rather than legalize charters statewide, SB 781 restricted them to St. Louis and Kansas City, Missouri’s only two metropolitan areas to have operated court-enforced desegregation programs. Combining critical policy analysis and economic geography, I link both desegregation and charter schools to urban neoliberalization, arguing that racialized processes of accumulation structured (and continue to structure) uneven development in such a way to make educational equity-based reforms necessary and their failures inevitable. Here too, St. Louis has an important story to tell. With deindustrialization and suburbanization resulting in a 63 percent decline in population in just over 60 years, St. Louis, like many other Rust Belt cities, has wholly embraced neoliberalism’s entrepreneurial ethos. Through public-private partnerships and a portfolio of tax incentives, St. Louis has sacrificed public education in its efforts to attract capital back to the city. Rather than mitigating these issues, the neoliberal restructuring of public education in St. Louis has embraced the same market logics that contributed to educational divestment and school segregation. I argue for a more expansive approach to critical policy analysis in education, one that addresses the limitations of reform within the existing political economy and relocates educational issues and their solutions within a larger struggle for racial and economic justice

ESR studies of the slow tumbling of vanadyl spin probes in nematic liquid crystals

ESR line shapes that are appropriate for slowly tumbling vanadyl spin probes in viscous nematic liquid crystals were calculated by the stochastic Liouville method. Because of the symmetry possessed by vanadyl, the analysis and interpretation of these line shapes was simplified considerably. Spectral line shapes agreed well with experimental spectra of VOAcAc in the nematic liquid crystal Phase V and BEPC. Deviations from Brownian rotational diffusion were noted. A slowly fluctuating torque analysis yielded good agreement with the experimental spectra

Controlling chaos in the quantum regime using adaptive measurements

The continuous monitoring of a quantum system strongly influences the emergence of chaotic dynamics near the transition from the quantum regime to the classical regime. Here we present a feedback control scheme that uses adaptive measurement techniques to control the degree of chaos in the driven-damped quantum Duffing oscillator. This control relies purely on the measurement backaction on the system, making it a uniquely quantum control, and is only possible due to the sensitivity of chaos to measurement. We quantify the effectiveness of our control by numerically computing the quantum Lyapunov exponent over a wide range of parameters. We demonstrate that adaptive measurement techniques can control the onset of chaos in the system, pushing the quantum-classical boundary further into the quantum regime

In Defense of Academic Free dom and Faculty Governance: John Dewey, the 100th Anniversary of the AAU P, and the Threat of Corporatization

This essay situates John Dewey in the context of the founding of the American Association of University Professors (AAUP) in 1915. We argue that the 1915 Declaration of Principles, together with World War I, provides contemporary academics important historical justification for rethinking academic freedom and faculty governance in light of neoliberalism and what we argue is an increased corporatization of higher education in the United States. By revisiting the founding of the AAUP and John Dewey’s role in the various debates surrounding the establishment of the organization—including his broader role as a public intellectual confronted by war, questions of duty and freedom, and the shifting boundaries of the professoriate—we argue that professors today should demonstrate academic freedom and reclaim faculty governance for the public good over private interests
