No Relief: The Politics Of Welfare Retrenchment, 1873-1898 And 1973-2002, Stephen Pimpare Jan 2002

No Relief: The Politics Of Welfare Retrenchment, 1873-1898 And 1973-2002, Stephen Pimpare

Dissertations, Theses, and Capstone Projects

No Relief compares the national repeal of AFDC in 1996 with the widespread campaigns against municipal poor relief that occurred throughout the United States some one hundred years earlier. In both eras businesses and the governments that depended upon them, threatened by growing labor power, civil unrest and the rising costs of poor relief, launched an attack against poor people and the limited benefits available to them. They did not do so directly but under cover of the Charity Organization Societies of the Gilded Age and conservative think tanks of the late twentieth century—"neutral" reform organizations that obscured the class-based …

Topological Sweep In Degenerate Cases, Eynat Rafalin, Diane Souvaine, Ileana Streinu Jan 2002

Topological Sweep In Degenerate Cases, Eynat Rafalin, Diane Souvaine, Ileana Streinu

Computer Science: Faculty Publications

Topological sweep can contribute to efficient implementations of various algorithms for data analysis. Real data, however, has degeneracies. The modification of the topological sweep algorithm presented here handles degenerate cases such as parallel or multiply concurrent lines without requiring numerical perturbations to achieve general position. Our method maintains the 0(n2) and 0(n) time and space complexities of the original algorithm, and is robust and easy to implement. We present experimental results.

When Legislatures Delegate Death: The Troubling Paradox Behind State Uses Of Electocution And Lethal Injection And What It Says About Us, Deborah W. Denno Jan 2002

When Legislatures Delegate Death: The Troubling Paradox Behind State Uses Of Electocution And Lethal Injection And What It Says About Us, Deborah W. Denno

Faculty Scholarship

This article discusses the paradoxical motivations and problems behind legislative changes from one method of execution to the next, and particularly moves from electrocution to lethal injection. This article first examines the constitutionality of electrocution, contending that a modern Eighth Amendment analysis of a range of factors, such as legislative trends toward lethal injection, indicates that electrocution is cruel and unusual. It then provides an Eighth Amendment review of lethal injection, demonstrating that injection also involves unnecessary pain, the risk of such pain, and a loss of dignity. The article next presents the author's study of the most current protocols …

Effects Of Heavier Truck Loadings And Super-Single Tires On Subgrades, Rodrigo Salgado, Daehyeon Kim Jan 2002

Effects Of Heavier Truck Loadings And Super-Single Tires On Subgrades, Rodrigo Salgado, Daehyeon Kim

JTRP Technical Reports

Due to their efficiency and economy, super-single tires have gradually been replacing conventional dual tires in the trucking industry. According to recent studies, super-single tires generate much higher vertical contact stresses than do conventional dual tires, resulting in larger deformations and more severe damage to the subgrade. In order to better assess the higher stresses generated by super-single tires and their effect on the subgrade, analyses are done taking into account soil plasticity rather than simple elastic analysis. In this study, the effects of super-single tires on subgrades for typical road cross-sections are investigated using plane-strain (2D) and 3D static …

Wetland Replacement Practices And Procedures For Indiana Highway Projects, James E. Alleman, Steve M. Graves Jan 2002

Wetland Replacement Practices And Procedures For Indiana Highway Projects, James E. Alleman, Steve M. Graves

JTRP Technical Reports

It is estimated that Indiana has already lost more than 80% of its original, native wetlands, and concerns have been expressed that some fraction, and perhaps even a sizable fraction, of these losses can be historically linked to highway construction associated with INDOT-related activities. These wetlands are important for several reasons, in that they help keep ground water and surface water clean, serve as reservoirs for floodwaters, help recharge groundwater, provide habitats for many species of animals, and serve as recreational areas. This underlying concern behind this accusation, therefore, is that the construction of state and federal roads historically carried …
