An important problem in number theory is to study the distribution of the non-trivial zeros of the Riemann zeta-function which, if one is willing to assume the Riemann Hypothesis, all lie on a vertical line. It is relatively easy to count how many of these zeros lie in a large interval, so the average spacing between consecutive zeros is easy to compute. However, it is a difficult and interesti...

In this talk I will agree with Harry Potter that one should "never trust anything that can think for itself, if you can't see where it keeps its brain". I’ll argue that humans need to locate intelligence, and that this issue poses problems for the disappearing computer. Bodies are the best possible example of located intelligence, of course, and interacting with another person is best done when...

The Internet is one of the major information sources for trip planning. However, sometimes it can be difficult to use, especially for planning a trip to a novel destination with a different culture. Using mixed methods which are comprised of process tracing, think aloud protocol, and clickstream analysis, this research explores the usability problems and barriers when American college students'...

Emerging technologies for children often require the involvement of children as test subjects in software development projects. Previous research studies have indicated that children behave differently than adults when involved in usability test sessions. Thus, children impose new opportunities and limitations in the evaluation and we still need to investigate proper and fruitful ways of involv...

Although the Alternative Uses divergent thinking task has been widely used in psychometric and experimental studies of creativity, the cognitive processes underlying this task have not been examined in detail before the two studies are reported here. In Experiment 1, a verbal protocol analysis study of the Alternative Uses task was carried out with a Think aloud group (N=40) and a Silent contro...

A think-aloud method was used to examine the content of information available to working memory during narrative comprehension in a CHI population. Twenty severe CHI participants (>1 year post-injury) and 20 controls talked aloud after they read each sentence of story narratives. Trabasso and Magliano's (1996a) verbal protocol analysis was then used to code for the production of inferential and...

the present study-both qualitative and quantitative--explored fifty efl learners’ preferences for receiving error feedback on different grammatical units as well as their beliefs about teacher feedback strategies. the study also examined the effect of the students’ level of writing ability on their views about the importance of teacher feedback on different error types. data was gathered throug...
