Distance education in formal undergraduate and graduate programs is the fastest growing segment of adult education, and many institutions and instructors are placing learning opportunities on the World Wide Web. Yet many adult learners do not possess the skills required to successfully complete Web

Ethics training in graduate psychology programs has blossomed in the last decade but the debate continues regarding how graduate ethics should be taught. While an effective model of ethics training is being discussed among professors, student input has been negligible, and information from students

In this work we show just how ommon and widespread the use of s alar elds has be ome in modern osmology, and we explain the underlying me hanisms for a variety of dierent topi s. First, we examine the ee t of a possible time variation in the Higgs va uum expe tation value on the Cosmi Mi rowave Ba kground and determine how observational data an onstrain su h a time variation. Next, we turn our attention to the analysis of s alar eld quintessen e models in an attempt to determine how to improve our ability to distinguish between dierent models, whi h make similar predi tions. As a nal topi , we examine s alar eld phantom models in the ontext of their ability to ameliorate the osmologi al oin iden e problem. ii To my mother iii ACKNOWLEDGMENTS

objective of this research is to provide three extensions to the inventory theoretic approach which was developed to explain carrier/mode selection. One of the strengths of the approach is that it accounts for both demand and lead time uncertainty when calculating total logistics costs. As the world’s economies become more and more interconnected, supply chains are growing in length and complexity resulting in increased lead time uncertainty. To manage costs effectively, supply chain managers need to account for lead time uncertainty. This research attempts to extend the inventory theoretic approach in three stand-alone papers that examine issues such as product value, variation in demand of lead time, equipment shortages, overbooking, and currency fluctuations across multiple methodologies. The first chapter introduces the inventory theoretic approach and gives a brief overview of the remaining chapters. Chapter two develops an optimization model based on the inventory theoretic approach in an effort to aide managers in selecting the best carrier/mode for their product. Findings suggest that total logistics costs are minimized by selecting a faster mode of transportation as the value of the product and the coefficient of variation in demand
