The effects of the relationship between racial identity and the nature and frequency of interracial contact on racial prejudice and social distance
In the light of social identity theory and contact theory, this study looked at the effects of racial identity on contact and prejudice. The sample consisted of 826 UCT students who belonged to the White and African population groups. Their mean age was 20.50 and they were 52.54% females and 47.46% …

Contact between models of rough surfaces containing spherical asperities
… brief introduction to the problem and importance of solid-solid contact as well as to the nature of surface topography is given. A number of experimental techniques, both direct and indirect, for determining the true area of contact between surfaces as well as a number of theories for predicting …

Selective assembly in deformable systems using templated assembly by selective removal
The current work presents the first demonstration of successful assembly of deformable polymer microspheres on patterned rigid substrates using Templated Assembly by Selective Removal (TASR). Also presented is a quantitative model for predicting the successful self-assembly of deformable materials …

Kinematic Analysis of a Threaded Fastener Assembly
… insertion, in an effort to determine the nature of contact between a bolt and nut during thread mating. The assembly problem was initially simplified as a two-dimensional analysis to gain an understanding about how contacts between the bolt and nut change during counter-clockwise motion. …

MULTI-SCALE DYNAMICS OF MECHANICAL SYSTEMS WITH FRICTION
Contact between rough surfaces occurs in numerous engineering systems and in many instances influences the macro behavior of the system. In many instances, the interaction between rough surfaces, affect the macro behavior of the system. Effective treatment of systems containing rough surface …

I am a Lifer: An ethnographic study of the impact of long-term incarceration on Lifers' identity.
The purpose of this research was to investigate the impact of the prison environment on Lifers' identity. It was hypothesized that individuals exposed to a prison environment, especially for long periods of time, are likely to experience conversion, or transformation to a "convict" or "inmate" …

Analytical investigation of fretting wear with special emphasis on stress based models
… oscillatory motion between two surfaces in contact under an applied normal load. It can cause either surface or subsurface initiated failure resulting in either fatigue or wear or both. Two distinct regimes – partial slip and gross slip are typically observed in fretting contacts. Due to the …
