Intrinsic and extrinsic motivations: Classic definitions and new directions.
- Contemporary Educational Psychology,
, 2000
"... Intrinsic and extrinsic types of motivation have been widely studied, and the distinction between them has shed important light on both developmental and educational practices. In this review we revisit the classic definitions of intrinsic and extrinsic motivation in light of contemporary research ..."

motivation in those around them. Most theories of motivation reflect these concerns by viewing motivation as a unitary phenomenon, one that varies from very little motivation to act to a great deal of it. Yet, even brief reflection suggests that motivation is hardly a unitary phenomenon. People have not only
Boosting the margin: A new explanation for the effectiveness of voting methods
- IN PROCEEDINGS INTERNATIONAL CONFERENCE ON MACHINE LEARNING
, 1997
"... One of the surprising recurring phenomena observed in experiments with boosting is that the test error of the generated classifier usually does not increase as its size becomes very large, and often is observed to decrease even after the training error reaches zero. In this paper, we show that this ..."

that this phenomenon is related to the distribution of margins of the training examples with respect to the generated voting classification rule, where the margin of an example is simply the difference between the number of correct votes and the maximum number of votes received by any incorrect label. We show
A Theory of the Learnable
, 1984
"... Humans appear to be able to learn new concepts without needing to be programmed explicitly in any conventional sense. In this paper we regard learning as the phenomenon of knowledge acquisition in the absence of explicit programming. We give a precise methodology for studying this phenomenon from ..."

High performance scalable image compression with EBCOT
- IEEE Trans. Image Processing
, 2000
"... A new image compression algorithm is proposed, based on independent Embedded Block Coding with Optimized Truncation of the embedded bit-streams (EBCOT). The algorithm exhibits state-of-the-art compression performance while producing a bit-stream with a rich feature set, including resolution and SNR ..."

Contract Cheating: A New Phenomenon in Cyber-Plagiarism
"... Contract Cheating is a new phenomenon, which is becoming an issue of concern at educational institutions in the UK, USA and Western Europe. Contract cheating is a form of academic dishonesty in which a student would pay someone (a contractor) to complete a given piece of coursework and then submit i ..."

Shell stabilizes nuclear instability: A new phenomenon
, 2003
"... Infinite nuclear matter mass model and the relativistic mean field theory show strong evidence of new neutron magic numbers 100, 150, 164; proton magic number 78 and new islands of stability around N=100, Z ≃ 62; N=150, Z=78; and N = 164, Z ≃ 90 in the drip-line regions of nuclear chart. It is shown ..."

. It is shown that shell effect stabilizes here the instability due to nuclear force giving rise to a new phenomenon; in contrast to the phenomena of fission isomer and super heavy elements where Coulomb instability is overcome by the same.

Toward a New Phenomenon: Super-Čerenkov Radiation
, 2008
"... In this letter a new coherent gamma emission mechanism, called Super-Čerenkov radiation, is introduced. The SČR is expected to take place when the charged particle is moving in a medium with a phase velocity vxph satisfying the super-coherent condition: cos θSC = vxphvγph ≤ 1. The results on an expe ..."

Does the “New Economy” Measure up to the Great Inventions of the Past?
- JOURNAL OF ECONOMIC PERSPECTIVES—VOLUME 14, NUMBER 4—FALL 2000—PAGES 49–74
, 2000
"... A widespread belief seems to be emerging, at least in the popular press, that the U.S. economy is in the throes of a fundamental transformation, one which is wiping out the 1972–95 productivity slowdown, along with inflation, the budget deficit, and the business cycle. A typical recent comment, in a ..."
