This article shows how criteria can be developed for evaluating English language textbooks. It presents a scheme for evaluation which can be used to draw up a checklist of items relevant to second (or foreign) language teaching. Instructions for using the checklist are given as a way of suggesting how teachers can evolve their own criteria for different situations.

The model results indicate thatVAC therapy is less costly and more effective than both traditional and advanced dressings. The results are robust to changes in key parameters, including the transition probabilities, the cost ofVAC therapy and the utility weights applied to health states.

Using delayed matching-to-sample, subjects chose from an array the nonsense trigram or quingram that most resembled the stimulus item. Each choice represented one particular error in word recognition, that is, matching on the basis of individual letters or on overall shape of the word. Kindergarten children (nonreaders) showed no consistent cue selections. First graders (beginning readers) matched on the basis of initial letter most frequently, then on final letter. They very seldom used overall shape. Adults (proficient readers) used complex strategies, including both visual and aural matching, and some adults used shape as a basis for choice.

Patients with diabetic foot ulcers in the Medicare sample treated with NPWT had a lower incidence of amputations than those undergoing traditional wound therapy; this finding was evident in wounds of varying depth in both populations studied.

Philippe Marcus opened a general discussion of the paper by Roger Newman: Should the passive lm not be signicantly involved in pit initiation (as you suggest), how would you explain that the time to initiation is very much dependent on the nature of the passive lm?Roger Newman responded: I never said that the passive lm is not involved in pit initiation. I understand (of course) that longer passivation gives a longer induction time for pitting. What I say is that the effects of parameters like alloy composition, environment composition, potential, and temperature, are not easily accommodated (at least not predictively) within a passive lm breakdown model, but fall out naturally from a modied Galvele type of model that uses pitting potential data (or, if one has the time, lower extremes of pitting potential distributions). Now I don't know whether or not the nest details of lm breakdown, detectable at the pA level or lower in electrochemical experiments (not nA to mA -those are already pits), and/or on very pure, at alloy surfaces, follow the same rules that we nd using pitting potentials on industrial or semi-industrial alloys. Those measurements have not been done. Actually I don't think stainless steel is necessarily the best model system for such studies. Under certain conditions, as shown by Bardwell many years ago, iron shows blizzards of pits that are clearly not impurity-particle-related; probably aluminum too. In stainless steel we really don't know whether pit initiation ever occurs without a microcrevice and/or an impurity particle.From the viewpoint of practical utility, the Galvele type of approach clearly has the advantage. The Critical Pitting Temperature (CPT) is a propagation-related transition below which metastable pits never become stable at any potential. My group has published extensively on that.
