Graphics and Ethos in Biomedical Journals    

This article describes a study that examined the tables and figures in articles from a basic research journal, The Journal of Cell Biology, and compared them to tables and figures from an applied medical journal, The New England Journal of Medicine. Comparison of graphics between the two journals shows sharp differences in terms of range of graphics types, visual consistency within and between articles, or use of color. As the articles take into account what is needed by different audiences, the graphics help to build the credibility of the journal. The study also addresses the question of how scientific visuals contribute to the persuasiveness of a writer, looking at how the graphics within an article affect the credibility or ethos of the writer.

Graphics and Invention in Engineering Writing    

This study reports on the use of graphics by engineers as a method of stimulating the writing process (rhetorical invention). Information presented here comes from working engineers, based on a questionnaire developed after informal conversations and then administered to 15 participants in private industry, with questions about specific writing genres and types of graphics. Results show that graphics have a powerful function in stimulating writing ideas. Although individual writers' preferences in graphics are strong, patterns could be seen in (1) overall number of graphics types used by each writer, (2) specific types of graphics used by each writer based on the writing genre, and (3) the most common types of graphics used overall.
