Distance Is Dead , Long Live Distance
For many educators, the phrase ‘from distance education to e-learning’ conjures up the view of an ‘evolutionary’ progression beginning with correspondence study and developed through more sophisticated technologies to its current identification with computers, the Internet, and the World Wide Web. For others, particularly those with little knowledge or experience of (and often equally little in...
متن کاملLong distance transport.
A few years ago, I attended a 1-day symposium on long distance transport at a national meeting in a country abroad. Towards the end of the day, as the participants became tired and no general agreement was in sight, one observer from an allied discipline remarked, "Why can't you translocation workers make any progress, you still discuss the same miserable old models that were proposed 40 years ...
متن کاملLong distance tunneling
Quantum tunneling between two potential wells in a magnetic field can be strongly increased when the potential barrier varies in the direction perpendicular to the line connecting the two wells and remains constant along this line. A periodic structure of the wave function is formed in the direction joining the wells. The resulting motion can be coherent like motion in a conventional narrow ban...
متن کاملLong-distance life rafting
Ordering and disordering electrons When a liquid is cooled rapidly, it can form a glass, a state stuck between liquid and solid. Two groups looked in detail into analogous dynamics in electronic systems. Sato et al. and Sasaki et al. studied layered organic materials with a triangular in-plane lattice. These materials can assume a state in which their charge distribution has a regular pattern—a...
متن کاملLearning Long Distance Phonotactics
Two questions regarding the non-local nature of long-distance agreement in consonantal harmony patterns (Hansson 2001, Rose and Walker 2004) are addressed: (1) How can such patterns be learned from surface forms alone? (2) How can we understand a a major feature of the typology—the absence of blocking effects? It is shown that a learner which generalizes only by making distinctions with respect...
