I knew that a conversation with the author would not settle such questions, because a man is not the same as his writing: in the last analysis, the questions had to be settled by the work itself.

These curves were derived by an analysis of extensive skywave measurement data.

It was stated earlier that one purpose of this study was to extend the analysis of variability of Onset and Completion in each of the 21 growth centers somewhat beyond that provided by the data in Tables 1 and 2.

Let us now put some flesh on the theoretical bones we have assembled by giving illustrations of roleplaying used for evaluation and analysis.

Finally, information is retrieved from the dictionary as required by stages of the translation process -- the grammatical description for sentence-structure determination, equivalent-choice information for semantic analysis, and target-language equivalents for output construction.

A third explanation is suggested by Richardson's analysis of Sukuma tone.

The general basis on which these common costs are assigned to differently measured units of service will be illustrated by the following highly simplified problem of an electric-utility cost analysis.

In order to simplify the exposition of a typical fully apportioned cost analysis, let us assume the application of the analysis to an electric utility company supplying a single city with power generated by its own steam-generation plant.

The theory claims to show by analysis that when we say, `` That is good '', we do not mean to assert a character of the subject of which we are thinking.

The force of the authors' analysis ( if indeed it has any force ) can be felt by the reader, I believe, only after three questions have been successfully answered.

Finally, just as no different issues are posed for thoughtful analysis by the foreshortening of time that may yet pass before the end of human life on this earth, but only stimulation and alarm to the imagination, the same thing must be said in connection with the question of what we may perhaps already be doing, by human action, to accelerate this end.

" In his book Indoctrination and Self-deception, Roderick Hindery tries to shed light on these tensions by contrasting them with impostors of authentic self-affirmation and altruism, by analysis of other-regard within creative individuation of the self, and by contrasting love for the few with love for the many.

This design-based analysis was discussed and developed by Francis J. Anscombe at Rothamsted Experimental Station and by Oscar Kempthorne at Iowa State University.

Since the randomization-based analysis is complicated and is closely approximated by the approach using a normal linear model, most teachers emphasize the normal linear model approach.
