  1. Unintended Consequences: Human-Medical Equipment Computer Interfaces

    Spectrum's Senior Associate Editor Samuel Moore sent me a note on an interesting news release titled, "Design of Patient Tracking Tools May Have Unintended Consequences" about a study by researchers at the University of Buffalo regarding the replacement of dry-erase patient status boards by electronic patient tracking systems. The researchers studied how new electronic patient-status boards were functioning in the emergency departments of two busy, university-affiliated hospitals. What the researchers found was while there were surface similarities between the manual and electronic systems, there were subtle differences in the design of the latter that affected how health-care providers communicated …

  2. Space Station's Computer Failure: It Was Inevitable

    James Oberg reports in an IEEE Spectrum webcast a very important story on the background to the NASA computer failure that occurred in June. Oberg stories states that, "The critical computer systems ... had been designed, built, and operated incorrectlyâ''and the failure was inevitable. Only being so relatively close to Earth, in range of resupply and support missions, saved the spacecraft from catastrophe." The problem was a cable short-circuit caused by moisture build-up, likely itself caused by a malfunctioning dehumidifier. But as Oberg writes, the short-circuit should not have caused the problems it did. "..in a shocking design …
