The problem of selecting appropriate mathematical models for use in studying hydrological phenomena has created a situation in which the choice of suitable models by hydrologic practitioners has become exceedingly complex. The extensive comments in the literature indicate that neither the traditional system of technical journals nor the more modern computer-based retrieval schemes have really solved the problem. Further examination shows that similar problems have arisen in many fields, hence a well organized attack on the specific problem of hydrologic model choice can have a more general application. The present problem is identified as a requirement to codify and make accessible to users information in a more directly user oriented format. The problem of model choice arises at several levels, ranging from decision on what fundamental structure to use, to choice of parameters, and on to model calibration and validation. This paper is focused on a scheme to aid in model structure choice. The essential ingredients of model structure choice, and indeed of many choice processes, are extracted and embedded in a generalized set theoretic mathematical notational framework in order to give some insight into the nature of the problem. Within this framework the specialized features of the model choice problem are analyzed, and a specialized model is developed for assisting in model choice and all problems similarly situated. These considerations lead to the development of a finite vector of objective statements with codified responses prepared by a panel of qualified researchers who are willing and able to construct the essential information in a user oriented format. It is required that the panel not only couch their information in objective oriented terms but that they also generate value judgments for the individual components. In this way, those using the system can take advantage of the expert opinions embedded in the model while, at the same time, tailoring the choice to meet their own specific needs and aspirations. This results in what is defined as a mathematical CHOICEMODEL. The implementation of a system for interactive computation of the CHOICEMODEL is described in detail, and the associated computer programs are presented in appendices. A detailed instruction manual is given, and the implementation of the method is illustrated by an easily understood model of the ingredients of the problem of selecting an 8-track stereo tape deck for home use. The plan is outlined whereby hydrologic choice models can be developed within the CHOICEMODEL system by a selected panel of expert EVALUATORS.

The main issue that this thesis deals with is the interaction between the Supreme Court of Canada’s recent decision in ESA vs. SOCAN and the new making available right introduced in Canada’s Copyright Modernization Act. The thesis analyzes the approach of the Supreme Court of Canada in ESA vs. SOCAN and examines the legislative history of the making available right on both global and domestic levels. A conclusion drawn by this thesis is that, the scope of the communication right in Canada’s Copyright Act should be expanded after the introduction of the making available right in order to cover a variety of digital transmissions including downloading, P2P file sharing and other interactive transmissions.

In today's world education and the resulting production of knowledge is highly valued as it can open the door to socioeconomic status and mobility. As a result, many students choose cultural and educational exchanges in a foreign country. The goal of this thesis is to better understand the decision making process international students experience prior to their study at an American university. Anchored in structuration theory, a two-step methodology was applied. First, a brief questionnaire survey was administered as a pilot study to gather preliminary data and initiate contact with participants. Second, interviews were conducted with foreign students to obtain background information and their reasoning for studying abroad. While most international students share common experiences in the decision making process, the temporal progression of "action steps" varies considerably among students. / Department of Geography
