Problem 3. True or False, and Justify (12 parts) [84 points] Circle T or F for each of the following statements to indicate whether the statement is true or false, respectively. If the statement is correct, briefly state why. If the statement is wrong, explain why. The more content you provide in your justification, the higher your grade, but be brief. Your justification is worth more points th...

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. While the ABD program enables the retailers to lock in a portion of the customer demand and use...

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 ...

The changes of the phase composition of iron oxide samples prepared by solgel method using single precursor both for nanoparticles and the matrix were studied by x-ray diffraction. Obtained data were analyzed by an approach using the Debye formula which is suitable for the size of particles up to about 10 nm. The phase composition of the nanoparticles was described by a core-shell model corresp...

The formation of Co(3)O(4) nano-scale colloid particles by gamma irradiation of CoSO(4) solutions was investigated. Solutions of 0.2-0.3 mM CoSO(4) at pH 6.0 and 10.6 (air-saturated and Ar-purged) were irradiated at an absorbed dose rate of 5.5 kGy h(-1). The resulting concentrations of H(2), H(2)O(2), Co(II) and Co(III) species in solution and the chemical composition and sizes of particles th...
