Since the late ' fifties the term structure of interest rates has attracted considerable attention from both theoretical and empirical economists. While potentially a very fruitful area for the application of the traditional methods of economic enquiry, the term structure has proved itself to be a potent testing ground for these tools, and consequently a wide range of sophisticated analytic devices have been introduced, Despite this, no general agreement has yet been reached and a number of crucial questions remain unanswered. It is our task in this dissertation to extend the enquiry into the South African context in an attempt to shed some light on the determination of the term structure of interest rates. Intro., p. 1.

Class of 2014 Abstract / Specific Aims: To assess and compare prescribing error-identification rates by healthcare professionals Methods: Pharmacists and nurses from Northwest Medical Center were invited to participate in this study. Participants completed a questionnaire that consisted of 10 fictitious patient prescriptions. They were asked to evaluate the accuracy of the prescriptions and indicated the type of error found, if any. The number of correctly identified prescribing errors, correct types of errors, and error identification rates for each group were calculated. Rasch analysis was used to assess the validity and reliability of the questionnaire. Wilcoxon and Rasch-Welch t-test were used to assess the difference in prescribing error-identification rates. Main Results: Thirty-five out of 700 nurses and 6 out of 20 pharmacists completed the questionnaire (response rate 5% and 30% respectively). Pharmacists had significantly higher error-identification rates compared to nurses (p = 0.0001). Additionally, pharmacists were able to correctly identify the type of error in each prescription (p < 0.0001). Conclusion: Pharmacists were significantly able to correctly identify more prescribing errors and more types of prescribing errors in 10 fictitious prescriptions compared to nurses. Several assumptions and limitations were identified in this study, therefore future studies are warranted.

This thesis addresses the problem of pricing perishable inventories such as airline seats and hotel rooms. It also analyzes the airline seat allocation problem when two airlines compete on a single-leg flight. Finally, several existing models for seat allocation with multiple fares on a single-leg flight are compared. The pricing framework is consistent with modern yield management tools which utilize restrictions such as weekend stayover to segment the market. One model analyzed considers a restriction which is irrelevant to one set of consumers, but which the others find so onerous that they will not purchase a restricted ticket at any price. If the consumers who do not mind the restriction are less price sensitive than those who find the restriction onerous, then the thesis shows that there is an optimal policy for a monopolist which will sell fares at no more than three price levels. When two restrictions are allowed in the model, if one is more onerous than the other in the sense that the set of consumers who would not buy a ticket with the first restriction is a subset of those who would not buy it with the second restriction, then the restrictions are said to be nested. If the sets of consumers who would not buy tickets with the first restriction is disjoint from those who would not buy with the second restriction, then the restrictions are said to be mutually exclusive. If two restrictions are either nested or mutually exclusive, then a monopolist needs at most four price levels with three types (i.e. combinations of restrictions) of product. With two general restrictions, the monopolist may need five price levels with four types of product. The pricing model is applied to restrictions which are based on membership in a particular organization. For example, employees of an airline are frequently eligible for special fares. Some airlines provide special fares for government employees or for employees of certain corporations. An analysis is given to help airlines understand the costs and benefits of such arrangements. A model of two airlines competing on a single-leg flight is developed for the case where the airlines have fixed capacity and fixed price levels for two types of fares-full and discount. The airlines compete by controlling the number of discount fares which they sell. The split of the market between the airlines is modelled in two different ways. First, the airlines might share the market for a fare class proportionally to their allocation of seats to that fare class. In this case, under certain conditions, there exists an equilibrium pair of booking limits for the discount fare such that each airline will protect the same number of seats for the full fare customers, even when the demands are random and stochastically dependent. The second market sharing model assumes that the two airlines share the market demand equally. In this case, when the demands are deterministic, then there is an equilibrium solution where each airline will protect enough seats to split equally the market for the full fares. Finally, three existing seat allocation models for multi-fare single-leg flights with stochastically independent demands are compared. It is shown that the optimality conditions for each of these models are analytically equivalent, thus providing a unified approach to this problem. / Business, Sauder School of / Graduate
