Notes that, although unillustrated text has changed from a string of unseparated words to the paragraph system, text-image relations present a continuous pattern of different degrees of interpretation and structuring for visual understanding. Suggests that human cognitive needs caused an adaptation in unillustrated text and that text illustrations…

Suggests that cohesion is best understood as a general perceptual phenomenon rather than a purely semantic one. Discusses three types of structural cohesion based on an analysis of technical texts: cohesion produced through thematic progression, parallelism, and graphic devices. (SR)

Investigates the role that ethos takes in the scientific papers of American glacial geologists. Analyzes the rhetorical strategies of five articles spanning the time period from 1839-1988. Discovers a coherent evolution of rhetorical strategies over this time period. (HB)

Outlines two rhetorical principles for producing iconic-mosaic texts--the principle of complementarity and the principle of compensation. Shows how these principles can be applied to practical problems in coordinating the writing and design processes in student projects. (RS)

Discusses the typical form and content of 40 theoretical scientific papers chosen from the most-cited papers in the "Science Citation Index." Demonstrates that the form of these papers is similar to that of experimental and methods papers but that the content differs substantially. (HB)

Quantifies specific elements of technical writing style in five award winning technical manuals where combined averages for the style elements are calculated. Compares these results to common criteria of good technical writing. Claims that wide variations among these manuals show that defining "good" technical writing is difficult. (HB)

Studies empirically the effects on reader performance of reduced text structure in technical writing texts. Reveals that removal of cues to local coherence produced reliable decrements in reader performance. Discusses results with regard to questions of information design. (HB)

Describes a small-scale experiment in which five professional writers were asked to revise brochure fragments based on the feedback from readers. Discusses the type of feedback collected from readers and how the experiment focused on the revision phase following formative text evaluation. (SG)

A study examined a set of 78 journal articles identified as influential in technical communication (published between 1988 and 1992) and a preliminary list of 63 articles frequently cited between 1993 and 1997. The texts were organized into six topical groups: profession, rhetoric and composition, document design, social construction and…

Writing research has long attempted to define and assess coherence in written prose; however the researchers have often ignored or inadequately met the needs of writing students who require a simple definition of coherence that they can use to revise their own prose. One exception is Joseph Williams, author of "Style: Ten Lessons in Clarity…
