Diversity in Retirement Wealth Accumulation
Examines household wealth by source, such as Social Security, home equity, savings, and defined benefit pensions; how their savings build up with age; and how total wealth accumulations vary by income, education, and race/ethnicity. Explores implications
EDUCO Schools in El Salvador: A Democratic Tree in a Globalized Forest?
This research on the Educacion con Participacion de Communidad (EDUCO) rural schools in El Salvador examined the nature of the reform and its impact on parent involvement and engagement for the local community; the underlying economic and political ideologies of EDUCO; and interpreted these findings to uncover the implications of the reform for democratic participation for the local school and community and for the more broadly constructed meaning of democracy, nationally and internationally
Early Sydney punk : methods in visual ethnography
This thesis explores the recollections of participants who were part of a cohort associated with a small punk venue known as the Grand Hotel, which operated at Railway Square, Sydney, between 1977 and 1979. While Australia’s first-wave moment has been increasingly recognised within a growing body of literature on punk, it has been considered almost exclusively in a music context. This study emphasises the sociality of punk subculture which has been largely absent from the record. The thesis comprises a creative component based on a series of video-recorded interviews, and a written exegesis. The video production, titled Distorted: Reflections on early Sydney punk, was developed through methods drawn from ethnography and other qualitative methodologies. The work presents discussion on a range of social, personal and political concerns of late 1970s Sydney through the reflections of participants. As such, it is a visual ethnography with a research focus on the past and on memory as articulated in a present setting. The written component of the thesis discusses aspects of cultural studies and subcultural theory in relation to punk as experienced in a post-colonial space, which is framed within an analysis of anthropologically-oriented ethnography. The text then discusses in detail the methodological underpinnings of the research. It is here that I advance an approach to audiovisual production which utilises computer assisted data analysis software within an analytical and conceptual framework drawn from grounded theory and narrative analysis
Accurate and efficient spin integration for particle accelerators
Accurate spin tracking is a valuable tool for understanding spin dynamics in
particle accelerators and can help improve the performance of an accelerator.
In this paper, we present a detailed discussion of the integrators in the spin
tracking code gpuSpinTrack. We have implemented orbital integrators based on
drift-kick, bend-kick, and matrix-kick splits. On top of the orbital
integrators, we have implemented various integrators for the spin motion. These
integrators use quaternions and Romberg quadratures to accelerate both the
computation and the convergence of spin rotations. We evaluate their
performance and accuracy in quantitative detail for individual elements as well
as for the entire RHIC lattice. We exploit the inherently data-parallel nature
of spin tracking to accelerate our algorithms on graphics processing units.Comment: 43 pages, 17 figure

Development of high speed power thyristor: The gate assisted turn-off thyristor
A high speed power switch with unique turn-off capability was developed. This gate-assisted turn-off thyristor was rated at 609 V and 50 A with turn-off times of 2 microsec. Twenty-two units were delivered for evaluation in a series inverter circuit. In addition, test circuits designed to relate to the series inverter application were built and demonstrated
Analysis of photographic developer solutions
The project has investigated the degradation products of colour
developing agents CD-3 and CD-4 that are likely to be present as significant
constituents in used colour developer solutions. Some of the major components
have been identified and confirmed earlier proposals made on model systems of
solutions of developing agents. Liquid chromatographic and capillary
electrophoretic methods have been established for the determination of the
individual components of the developer solutions and both Kodak and competitor
products have been examined. [Continues.
