Immigrant Students, Urban High Schools: The Challenge Continues

Uses examples from New York, Houston, and North Carolina to explore some of the innovative programs that are helping immigrants become educated citizens and productive workers, and highlights issues related to establishing a new educational framework

High School Students at Risk: The Challenge of Dropouts and Pushouts

Analyzes the factors contributing to high dropout rates at schools in New York, Chicago, and Las Vegas. Explores the available alternatives and program reforms that have been implemented to improve graduation rates at urban schools

Detection of the transitional layer between laminar and turbulent flow areas on a wing surface

A system is disclosed for detecting the laminar to turbulent boundary layer transition on a surface while simultaneously taking pressure measurements. The system uses an accelerometer for producing electrical signals proportional to the noise levels along the surface and a transducer for producing electrical signals proportional to pressure along the surface. The signals generated by the accelerometer and transducer are sent to a data reduction system for interpretation and storage

Tests show that aluminum welds are improved by bead removal

Tests with 2218-T87 aluminum alloy plate indicate improvements in strength, ductility, fatigue properties, and burst pressure result when one or both of the top and bottom weld beads are removed. There is, however, a drop in yield strength. The consistency of test data is considerably improved by weld bead removal

[Review of] Susan Olzak. The Dynamics of Ethnic Competition and Conflict

Susan Olzak’s work, The Dynamics of Ethnic Competition and Conflict, is informative and contributes to an understanding of ethnic violence from an historical perspective. The central finding is that ethnic/racial conflict arises from an increase in intergroup competition for social resources. Exploring economic and political competition in the United States from 1877 to 1914, Olzak concludes that violence is most apt to occur when members of a disadvantaged ethnic/racial group experience greater equality of opportunity. This new environment creates a situation whereby members of a formerly segregated group become rivals for social awards. An environment which contains several disadvantaged groups competing for rewards -- a situation which existed in the period under investigation through a combination of racial migration from the south and European immigration -- leads to attacks on groups least able to defend themselves. Thus, the “..... breakdown of racially and ethnically ordered systems unleash forces of competitive exclusion against the least powerful targets in the system” (224). Olzak suggests this situation occured [occurred] with African Americans as European groups achieved social mobility

[Review of] David Delaney. Race, Place, & the Law

David Delaney\u27s work is informative and contributes to an understanding of race relations and the legal system. The central finding is that race relations exist in different spatial contexts at the same time. The author begins with the case Commonwealth v. Aves, 18 Pick. 193 (1836) which focuses on a young slave girl, Med and her freedom. The cause of action involved the movement of the servant girl to Massachusetts by her Louisiana master. The master was visiting relatives. Under Louisiana law Med was a slave, but Massachusetts law did not permit slavery
