The Influence Of Pore Fluids On Shear Strength And Stress-Strain Behavior Of Granular Soils, Prasanna Ratnaweera

Dissertations

When a dry granular soil is subjected to an external load, the stresses are transferred through mineral to mineral contacts. The shear strength of such a soil is governed by its contact properties. Presence of a thin layer of fluid between mineral to mineral contacts in a saturated soil will alter its contact properties. Therefore any change in the physical properties of pore fluid can logically be reasoned to influence the deformation characteristics of granular soils.

To investigate the influence of pore fluid viscosity on shear strength and stress-strain behavior of a soil, a series of consolidated drained triaxial tests …

Juvenile Justice: An Examination Of Disparities In Dispositions, Michael P. Brown

Dissertations

The present study tests the utility of status characteristics and expectation states theory in the context of the juvenile court. The theory contends that there is dispositional certainty when case related factors are consistently rated serious or nonserious; the severity of the sanction will reflect the seriousness of the case. However, the likelihood of sentencing disparities based on individual characteristics (e.g., race and SES) increases as case related factors become increasingly inconsistent, with some rated serious and others rated nonserious.

Data to test this theory were collected from the Kalamazoo County Juvenile Court, Kalamazoo, Michigan in June and July, 1990. …
