and two anonymous reviewers from Management Science who provided helpful and insightful comments on earlier versions of this paper. Abstract Engineering design often involves a very complex set of relationships among a large number of coupled problems. It is this complex coupling that leads to iteration among the various engineering tasks in a large(More)
During June and August 1992, we tested a new technology designed to exclude cattle from specific areas such as riparian zones. Technology consisted of an eartag worn by the animal that provides an audio warning and electrical stimulus to the ear as the animal approaches the zone of influence of a transmitter. The transmitter emits a signal that narrowly(More)

There is a compelling case, based on research in statistics education, for first courses in statistical inference to be underpinned by a staged development path. Preferably over a number of years, students should begin working with precursor forms of statistical inference, much earlier than they now do. A side benefit is giving younger students more(More)
Discovering patterns in strings is a central task in analyzing molecular sequences. One pattern discovery problem is to find a pattern that occurs as a substring in each member of a given set of strings. Additionally, occurrences of this pattern are allowed to have up to some specified number of errors, so the occurrences may not exactly match the pattern.(More)

These lectures serve as an introduction to the renormalization group approach to effective field theories , with emphasis on systems with a Fermi surface. For such systems, demanding appropriate scaling with respect to the renormalization group for the appropriate excitations leads directly to the important concept of quasiparticles and the connexion(More)
course embraced a dialogical approach to the design, coordination, and collaboration of global, telecollaborative learning activities (Bur-niske, 2001). Dialogue and inquiry may prove difficult, however, for participants conditioned by hierarchical social systems reinforced through prescribed curricula and administrative hegemony. Nevertheless, a global,(More)
