When teachers initiate the process of student-kept portfolios in high school language arts, they draw upon implicit beliefs about knowledge, learning, and teaching. This study shows that why we use portfolios is as important as how we use them. / I begin by exploring the century old history of teaching high school English wherein we can identify a contrast to portfolios, what we call traditional education. The ethical, classical, grammar based and non-academic traditions have shaped our definition of the subject, as well as the content. By examining where portfolios come from in the history of teaching English, we can then uncover the beliefs that are implicit in using them. / Next, I review the work of Tolstoy, Ashton-Warner and Dewey who developed innovative teaching methods based on an original set of beliefs. I connect them to beliefs that are implicit about knowledge, learning, and teaching in today's portfolio classrooms. / Like these three innovators, teachers in today's portfolio classrooms have reinterpreted their role as teacher and evaluator. The portfolio teachers in this study hold common beliefs that relate to both the history of the subject and to the work of innovative educators in our past. These common beliefs, found in the concluding chapter of this thesis, are the reasons why some teachers use portfolios.

The fixed maturity, pricing and cash flow characteristics of fixed-income instruments like bonds distinguish them from equities and complicate the application of mean-variance optimization techniques to bond portfolio management. This report examines the challenges involved and reviews some of the theoretical term structure models and empirical estimation methods that have been proposed to address them. An empirical study is conducted which finds evidence of increased interest rate volatility, which affirms the need for a portfolio approach in fixed-income investing. An optimal portfolio of bond funds constructed using the Markowitz method is found to provide the best risk-return profile over the chosen study period, suggesting the viability of this approach as an alternative to holding bonds. / text
