visualization skills demonstrate that there are differences in skill levels between students who are potential majors and those who are not, suggesting that students may self-select geology as a major based on their visualization abilities before significant course work. Students in introductory geology courses with very poor spatial skills are more likely to receive poor final course grades th...

Many audio and multimedia applications would benefit from the ability to classify and search for audio based on its characteristics. The audio analysis, search, and classification engine described here reduces sounds to perceptual and acoustical features. This lets users search or retrieve sounds by any one feature or a combination of them, by specifying previously learned classes based on thes...

The discussion of moral dilemmas is often proposed as one way to teach ethics. But can ethics be taught to everyone? Do participants’ value orientations predict the acquisition of moral competence in an educational context? This study presents data from an evaluation of a course on the social consequences of information technology (IT). IT-related dilemma discussions were used extensively in th...

For any partition of {1, 2, . . . , n} we define its increments Xi, 1 ≤ i ≤ n by Xi = 1 if i is the smallest element in the partition block that contains it, Xi = 0 otherwise. We prove that for partially exchangeable random partitions (where the probability of a partition depends only on its block sizes in order of appearance), the law of the increments uniquely determines the law of the partit...

W model a situation in which two retailers consider launching an “Advance Booking Discount” (ABD) program. In this program, customers are enticed to precommit their orders at a discount price prior to the regular selling season. However, these precommitted orders are filled during the selling season.

C a retailer who sells perishable seasonal products with uncertain demand. Due to the short sales season and long replenishment lead times associated with such products, the retailer is unable to update demand forecasts by using actual sales data generated from the early part of the season and to respond by replenishing stocks during the season. To overcome this limitation, we examine the case ...
