Aberdeen polygons: computer displays of physiological profiles for intensive care

Article Abstract:

Polygon patterns are useful for information gathering about the physiological state of patients, especially, in the intensive care units. Each side of an Aberdeen polygon denotes a norm for an important sign. Deflections from the norm are represented by triangles extending from the side of the polygon. Triangles extending inward indicate negative deviations and triangles extending outward indicate positive deviations from the norm. Diagnosis of the nature and the severity of a patient's physiological state becomes easier after physicians learn to recognize the patterns.

The messaging threshold in computer-mediated communication

Article Abstract:

Individuals using computer-mediated communication (CMC) to prepare written reports show a messaging threshold as the relation between communication expenses and message urgency affects the decision to send messages. The CMC group members show less spontaneous social-emotional and time-critical behavior than individuals using face-to-face (FTF) communication. The CMC group shows greater cooperation and norm-strengthening behavior. The CMC members take longer to prepare the reports but the quality of their work is similar to that of the FTF members.

Computer mouse use and cumulative trauma disorders of the upper extremities

Article Abstract:

Workers' compensation claims for 1986 to 1993 were analyzed to study cumulative trauma disorders of the upper extremities (CTDUEs) associated with increasing use of computer and computer mouse. Although computer mouse-related CTDUEs are very small relative to all claims for the period covered, the problem is increasing and merits more research and attention.
