Systems, interactions and macrotheory

A significant proportion of early HCI research was guided by one very clear vision: that the existing theory base in psychology and cognitive science could be developed to yield engineering tools for use in the interdisciplinary context of HCI design. While interface technologies and heuristic methods for behavioral evaluation have rapidly advanced in both capability and breadth of application, progress toward deeper theory has been modest, and some now believe it to be unnecessary. A case is presented for developing new forms of theory, based around generic “systems of interactors.” An overlapping, layered structure of macro- and microtheories could then serve an explanatory role, and could also bind together contributions from the different disciplines. Novel routes to formalizing and applying such theories provide a host of interesting and tractable problems for future basic research in HCI

Legal Implications of Drug Testing in the Private Sector

Drug testing, or perhaps more appropriately substance abuse testing, is a double-edged sword in the private sector. Not only can the employer be sued as the result of testing but he can be sued for not testing. Private employers find themselves in the classic damned if you do, damned if you don\u27t situation. Large corporations are seen as deep pockets when matched against one of their employees and if the plaintiff\u27s lawyer can find an issue and then get his or her case to the jury, corporate pockets can be very deep indeed. Hence, before examining the legal implications of testing, there is good reason to consider the legal implications of not testing
