Since the breakdown of bipolarity, the international community had to cope with independence movements spreading in Eastern, Central and Southeastern Europe. Given the peculiar coercive character of the Soviet and Yugoslav Federations and the Soviet Union’s hegemonial rule in Central Europe, the wish for independent statehood can be understood as a sum of single secessionist movements. This art...

Current pointing techniques provide no adequate way to select very small objects whose movements are fast and unpredictable, and theoretical tools –such as Fitts' law– do not model unpredictable motion. To inform the design of appropriate selection techniques, we studied how users performed when selecting moving objects in a 2D environment. We propose to characterize selection performance as a ...

The U.S. Department of Justice released the first national guide for collecting and preserving eyewitness evidence in October 1999. Scientific psychology played a large role in making a case for these procedural guidelines as well as in setting a scientific foundation for the guidelines, and eyewitness researchers directly participated in writing them. The authors describe how eyewitness resear...

The rim partials of a church bell (those with an antinode at the soundbow) generate the strike pitch or perceived note of the bell. The spacing in frequency of the higher rim partials has an important effect on the tonal quality of the bell. Investigations into the partial frequencies of 2752 bells, both bronze and steel, of a wide variety of dates, founders and sizes, show a simple and unexpec...

Data management in a networked world presents us with some of the same challenges that we’ve seen in the past, but emphasizes our ability to deal with scale, in that there are several orders of magnitude more database users, and database sizes are rising more quickly than Moore’s law. We have considerably less control over the structure of the data than in the past and must efficiently operate ...
