eResearch - Paradigm Shift or Propaganda

eResearch is a concept or word which has come into vogue in academic research circles since 2000. Fundamentally, it is collaborative and interactive research made possible by the Internet and data and computational grids. But like any other new concept, it can and has been abused and misused by people keen to “jump on the bandwagon”. eResearch presents many challenges, both technical and organi...

Business Analytics: Radical Shift or Incremental Change?

Shift-or string matching with super-alphabets

Given a text T [1 . . . n] and a pattern P [1 . . .m] over some alphabet Σ of size σ, we want to find all the (exact) occurrences of P in T . The well-known shift-or algorithm solves this problem in time O(ndm/we), where w is the number of bits in machine word, using bit-parallelism. We show how to extend the bit-parallelism in another direction, using super-alphabets. This gives a speed-up by ...

Does mental context drift or shift?

Theories of episodic memory have generally proposed that individual memory traces are linked together by a representation of context that drifts slowly over time. Recent data challenge the notion that contextual drift is always slow and passive. In particular, changes in one's external environment or internal model induce discontinuities in memory that are reflected in sudden changes in neural ...
