False statements took longer to process than positive statements (deciding about ...

Non-structured programs are diicult to parallelize. First, the scope of the non-structured statements may interact and the execution trajectories can overlap, preventing the unique determination of the scope of a control statement. Second, even if the scope of a non-structured statement is determined and is converted into a while loop, this while loop is still diicult to parallelize due to the ...

Intelligent Tutoring Systems are often modeled after human tutors; however, the effectiveness of this strategy is yet to be determined. Research on media interactions suggests that behaviors with humans are similar to those with computers. Intelligent Tutoring System studies have said the opposite. In this study we compared a human-human and a humancomputer tutoring system in terms of metacogni...

The advent of information technologies has raised public concern regarding privacy, as documented by the results of several surveys.
