Double Consciousness in Today’s Black America

In The Souls of Black Folk, W.E.B. Du Bois introduces double consciousness as a result of racial prejudice and oppression. Explained as a state of confliction felt by black Americans, Du Bois presents double consciousness as integral to understanding the black experience. Later philosophers question the importance of double consciousness to current race discussions, but this paper contends that double consciousness provides valuable insights into black and white relations. To do this, I will utilize the modern slang term, “Oreo,” to highlight how a perceived incompatibility between blacks and whites could prevent America from achieving a greater unit

Forensic Interviews of Children: The Components of Scientific Validity and Legal Admissibility

The problems associated with assessments of children\u27s reports of victimization in criminal proceedings came to national attention during the 1980s and 1990s in a series of highly publicized trials of daycare staff. Walker describes information that professionals need to know if they are to conduct valid interview of children in forensic contexts

Research on speech understanding and related areas at SRI

Research capabilities on speech understanding, speech recognition, and voice control are described. Research activities and the activities which involve text input rather than speech are discussed

The promise and practice of e-learning within complex tertiary environments

In advance of a change in learning management systems at a tertiary institution in New Zealand, the authors undertook a research study, the purpose of which was to provide a ‘snap-shot’ of existing online instructional practice within their School. They sought to identify existing pedagogical and technical issues and staff attitudes and preparedness for the new software. Although they found considerable staff good will toward e-learning, a number of problems were identified in the study. Findings from research have been organized and are discussed within five categories, including vision, skills, incentives, resources, and action plan. Conclusions describe plans for reorganizing how and in what manner e-learning can be supported within complex social environments, such as universities, when resources are limited

CO2 laser annealing of 50-microns-thick silicon solar cells

A test program is conducted to determine thin solar cell annealing effects using a laser energy source. A CO2 continuous-wave laser was used in annealing experiments on 50 micrometers-thick silicon solar cells after proton irradiation. Test cells were irradiated to a fluence of 1.0 x 10 to the 12th power protons/sq cm with 1.9 MeV protons. After irradiation, those cells receiving full proton dosage were degraded by an average of 30% in output power. In annealing tests laser beam exposure times on the solar cell varied from 2 seconds to 16 seconds reaching cell temperatures of from 400 C to 500 C. Under those conditions annealing test results showed recovery in cell output power of from 33% to 90%

A fibre optic, four channel comparative photometer

Development of a four channel comparative photometer is described. Tests have shown that it is stable from night to night and is capable of working in very poor sky conditions. Even when the sky conditions are so poor that stars are barely visible, light curves can still be obtained with an r.m.s. value of 0.0016 mag., provided that integration times that are long compared with the transparancy changes are possible
