                  an integrated part of everyday activities. The most used
                  devices are desktop PCs or laptops, tablet PCs, and
                  smartphones, which mainly differ with regard to the screen
                  size and the method of data entry. Given the growing diffusion
                  of technological devices, the increasing ownership of multiple
                  devices, and the resulting different usage patterns between
                  devices, it is essential to gain insights into which devices
                  are used for which activities. The aim of this analysis was to
                  examine a total of 21 activities people engage in on a
                  day-to-day basis with regard to desktop PC or laptop, tablet
                  PC, and smartphone usage. When considering user
                  characteristics with regard to technology, one of the most
                  influential factors is the user's age. Therefore, the sample
                  (N{\thinspace}={\thinspace}1923) was analyzed with regard to
                  four different technology generations. Results show that there
                  are significant differences in device usage between the
                  activities under study and between the four analyzed
                  technology generations.",

  abstract =     { Ubiquitous technology depends upon imposing
                  standards. Choices in function and form reflect the
                  homogenization of artifacts, necessitated by the intentions of
                  experts to satisfy a plurality of users. In material publics,
                  users with expert knowledge can develop customized artifacts
                  satisfying desired affordances or aesthetics. This project
                  involves a media archaeology of computer keyboard design to
                  explore the relationship between experts, publics, and the
                  creation of these artifacts. Participation in these
                  communities and study of enthusiast records result in a
                  public-expert knowledge. The importance granted to minutia of
                  design, from the choice of plastics to spring tensioning,
                  parallels new form factors that reflect highly personalized
                  choices. These reassert user control over the materiality of
                  an otherwise ubiquitous and mundane mediating
                  artifact. Publics then create a new political materiality by
                  recomposing artifacts beyond what commercial expertise
                  prescribes. }

It is shown that the test has a prescribed level of significance protection against error of the first kind for any combination of true hypotheses. The power properties of the test and a number of possible applications are also discussed.},
