Predictions of pressure-induced transition temperature increase for a variety of high temperature superconductors

A wide variety of superconducting oxides are used to test a general model of high pressure induced transition temperature (T c) changes. The T c 's vary from a low of 24 K to a high of 164 K. Although the model is capable of predicting both increases and decreases in T c with pressure, only superconductors that exhibit an increase are considered at this time. Predictions are made of the maximum T^ cP theo for 15 super-conductors as a function of their compressibilities. The theoretical results generally agree well with experiment. This model of T c as a function of pressure is derived from a recent successful phenomenological theory of short coherence length superconductivity.Comment: 9 pages. 1 table, 0 figure

Balancing Local Assessment and Statewide Testing: Building a Program that Meets Student Needs

This document discusses the components of assessment for those who are considering adding local assessments to required statewide testing of K-12 students. These components include technical adequacy, local-level opportunity, and how to link to state and local standards. Attributes of a model local assessment program are discussed and examples are given. There are also four key questions evaluators and teachers should ask themselves if they are considering a local-level assessment, including the cost feasibility.
