abstract textbooks play an important role in english language teaching (elt), particularly in the english as a foreign language (efl) context where it provides the primary linguistic input. the present research was an attempt to comparatively evaluate the touchstone series in terms of compliment and complaint speech acts. four touchstone textbooks (book 1, book 2, book 3, and book 4) were selec...

Benchmarks are valuable for comparing processor performance. However, porting and running processor benchmarks on new platforms can be di cult. Touchstone, a simple addition benchmark, is designed to overcome portability problems, while retaining performance measurement accuracy. In this paper, we present experimental results that show Touchstone correlates strongly with processor performance u...

Critical theory is one of the most influential theoretical frameworks influencing scholarship within the field of adult and community education. This chapter outlines what constitute the chief elements of critical theory using Horkheimer’s (1937/1995) classic essay as a touchstone for this analysis. It argues for a set of adult learning tasks that are embedded in this analysis and that apply bo...

This paper describes the Intel Touchstone Gamma Prototype, a distributed memory MIMD parallel computer based on the new Intel i860 floating point processor. With 128 nodes, this system has a theoretical peak performance of over seven GFLOPS. This paper presents some initial performance results on this system, including results for individual node computation, message passing and complete applic...
