A study of the oral communication experiences and training of obstetric sonographers can provide insight into the complex expectations these medical professionals face as they complete their technical tasks and communicate with patients. Unlike other diagnostic medical professionals, obstetric sonographers are expected to provide detailed information to patients during the exam, a practice not typically found in the work of other types of medical diagnostic professionals. This study presents the results of interviews with 23 obstetric sonographers who described their communication experiences and their views on sonographer training in communication. Results suggest that sonographers experience complex communication challenges in the workplace that are not typically addressed in their education, nor are they officially recognized in the official discourse of their profession.

Florence Nightingale is usually pictured as an angelic nurse tending to British soldiers in military hospitals during the Crimean War. Although Nightingale was indeed a tender of soldiers, she was also an administrator, advocate for the common soldier, and proponent of the use of statistics and information design. This article examines Nightingale's rose diagrams, which she designed following her service as the director of nurses at a field hospital in the Crimean War. When the war ended, Nightingale was asked by the queen to write a report on the poor sanitary conditions and make recommendations for reform. When, after six months, the government did not act on the reforms, Nightingale decided to write an annex to the report, in which she would include her invention, the rose diagrams. Nightingale's ultimate success in persuading the government to institute reforms is an illustration of the power of visual rhetoric, as well as an example of Nightingale's own passionate resolve to right what she saw as a grievous wrong.

This paper is a critique of current approaches to the development of computer graphing and graph visualization programs. Developers of these programs model the user as an individual problem solver who is reliant on perceptual skills to create and interpret graphed information. Such a model of graphing is ill-suited to meet the complex needs of real users, a supposition that is supported by work in two major areas of graphing theory and research: the sociology of science and the educational research of mathematics and scientific students. These areas have not been traditionally cited when planning computer graphing or visualization programs or when assessing their usability. A review of the literature in these fields reveals that an over-reliance on a user's perceptual skills is unlikely to result in successful graph practices.
