In "Concise Guide to Technical Communications", the issue of ethics is covered in the span of 14 pages. The authors have given the reader a few real-life examples of situations, of which a couple are shared with "Ethics in Technical Communication". Additionally, in the "Ethics. . ." text, the authors draw upon 2 other examples--the Three-Mile Island incident, and the Pentium chip privacy problem.
Of the four perspectives of ethics discussed in chapter 3 of the "Ethics. . ." textbook, "Concise Guide. . ." leans toward the 'ethics of care', though not in the strict sense noted in the "Ethics" text. An example from "Concise Guide" is on page 100, where there is a list of 'obligations', based on the publication. "Media Ethics: Cases and Moral Reasoning", where the editors developed the responsiblities one has to everyone involved, not only within the technical arena, but in day-to-day living.
