Meme-tracking and the Dynamics of the News Cycle
, 2009
"... Tracking new topics, ideas, and “memes” across the Web has been an issue of considerable interest. Recent work has developed methods for tracking topic shifts over long time scales, as well as abrupt spikes in the appearance of particular named entities. However, these approaches are less well suite ..."

Sampling—50 years after Shannon
- Proceedings of the IEEE
, 2000
"... This paper presents an account of the current state of sampling, 50 years after Shannon’s formulation of the sampling theorem. The emphasis is on regular sampling, where the grid is uniform. This topic has benefited from a strong research revival during the past few years, thanks in part to the math ..."

Catastrophic regime shifts in ecosystems: linking theory to observation.
- Trends Ecol Evol
, 2003
"... Occasionally, surprisingly large shifts occur in ecosystems. Theory suggests that such shifts can be attributed to alternative stable states. Verifying this diagnosis is important because it implies a radically different view on management options, and on the potential effects of global change on s ..."

Occasionally, however, this scenario is interrupted by an abrupt shift to a dramatically different regime Similar dramatic regime shifts are now documented for a range of ecosystems, including the open ocean in which
Pricing in Computer Networks: Reshaping the Research Agenda
- ACM Computer Communication Review
, 1996
"... As the Internet makes the transition from research testbed to commercial enterprise, the topic of pricing in computer networks has suddenly attracted great attention. Much of the discussion in the network design community and the popular press centers on the usage-based vs. fiat pricing debate. The ..."

A pervasive millennial-scale cycle in North Atlantic Holocene and glacial climates
- Science
, 1997
"... Evidence from North Atlantic deep sea cores reveals that abrupt shifts punctuated what is conventionally thought to have been a relatively stable Holocene climate. During each of these episodes, cool, ice-bearing waters from north of Iceland were advected as far south as the latitude of Britain. At ..."

Topic initiation, development and shift in conversations Topic Initiation, Development And Shift In Conversations
"... This study is a replication of Coates ’ study on conversations between women friends, and seeks to test Coates ’ findings on topic development and shift in women’s conversations using data on female British Asian friends. Coates ’ study (1996, 1998), using data on white women friends, found that in ..."

Automated evaluation of coherence in student essays
- In Proceedings of LREC 2000
, 2000
"... This paper explores the role of Centering Theory, in particular Rough-Shift identification, in locating abrupt topic shifts in student essays. Rough-Shifts within student paragraphs are generated by short-lived topics and are therefore indicative of poor topic development. We develop a Rough-Shift-b ..."

LETTERS An abrupt wind shift in western Europe at
, 2008
"... The Younger Dryas cooling 12,700 years ago is one of the most abrupt climate changes observed in Northern Hemisphere palaeoclimate records1–4. Annually laminated lake sediments are ideally suited to record the dynamics of such abrupt changes, as the seasonal deposition responds immediately to climat ..."

Topic

"... Attention serves several functions related to information processing. It selects certain events or objects in the environment to focus on and maintains focus on the object of interest while information provided by that object is processed. Additionally, while attention is focused on one object, shif ..."
