Forward exchange rate unbiasedness is rejected in tests from the current floating exchange rate era. This paper surveys advances in this area since the publication of Hodrick's (1987) survey. It documents that the change in the future exchange rate is generally negatively related to the forward discount. Properties of the expected forward forecast error are reviewed. Issues such as the relation of uncovered interest parity to real interest parity, and the implications of uncovered interest parity for cointegration of various quantities are discussed. The modeling and testing for risk premiums is surveyed. Included in this area are tests of the consumption CAPM, tests of the latent variable model, and portfolio-balance models of risk premiums. General equilibrium models of the risk premium are examined and their empirical implications explored. The survey does not cover the important areas of learning and peso problems, tests of rational expectations based on survey data, or the models of irrational expectations and speculative bubbles.

Systolic architectures, which permit multiple computations for each memory access, can speed execution of

developed specifically to make the task of scheduling easy. As a result, it has been possible to develop a powerful scheduling algorithm that yields optimal and near-optimal schedules for iterative computations. This novel architecture and this scheduling algorithm are the topic of this paper.

The increasing quality and ever growing presence of technology in and outside the classroom allows teachers to experiment with new forms of lesson delivery, from video production (Gromik, 2007), to blogging (Pinkman, 2005) and teacher produced podcasts (Diem, 2005). Recently however a new form

Abstract—ESL (Execution Support Language) [5] is a language for encoding execution knowledge in embedded autonomous agents. It is similar in spirit to RAPs [2] and RPL [7], and RS [6], and its design owes much to these systems. Unlike its predecessors, ESL aims for a more utilitarian point

This paper introduces architectural and interaction patterns for integrating crowdsourced human contributions directly into user interfaces. We focus on writing and editing, complex endeavors that span many levels of conceptual and pragmatic activity. Authoring tools offer help with pragmatics, but for higher-level help, writers commonly turn to other people. We thus present Soylent, a word processing interface that enables writers to call on Mechanical Turk workers to shorten, proofread, and otherwise edit parts of their documents on demand. To improve worker quality, we introduce the Find-Fix-Verify crowd programming pattern, which splits tasks into a series of generation and review stages. Evaluation studies demonstrate the feasibility of crowdsourced editing and investigate questions of reliability, cost, wait time, and work time for edits.

The era of low power microelectronics began with the invention of the transistor in the late 1940 's and came of age with the invention of the integrated circuit in the late 1950's. Historically, the most demanding applications of low power microelectronics have been battery operated

different modules. Such capabilities are part of the so-called electronic system-level (ESL) design automation. ESL design automation has caught much attention from the industry recently. In general, it has been shown that the code density and simulation time can be improved by 10X and 100X, respectively

The primary purpose of this study was to examine ESL teachers ' perceptions of the impact of a revised curricular framework containing performance objectives on their preparation for, implementation in, and evaluation of their classes. Teachers ' agency in curriculum making was also
