Testing against Changing Correlation

A Framework for Testing Selforganisation Algorithms

The characteristics of self-organising, adaptive systems (SOAS) lead to a signi cantly higher exibility and robustness against an ever-changing environment. This exibility makes it hard to test these systems adequately, which is, however, inevitable in order to assure their quality. As a part of our vision of testing SOAS, we present a framework for testing selforganisation (SO) algorithms. The...

Doubts on the validity of correlation as a validation tool in second language testing research: the case of cloze testing

The statistical analysis technique of correlation has extensively been used in second/ foreign language testing research for a variety of purposes. Most commonly, the technique has been used to validate newly constructed language tests (particularly cloze tests) against previous supposedly valid measures. Tests such validated are meant to substitute the older ones, and based on these newly vali...

Precise numerics versus theory for correlation ratchets.

Fluctuation-induced transport in a correlation ratchet driven by both additive Gaussian white and additive Ornstein-Uhlenbeck (colored) noise is studied numerically and interpreted against theoretical predictions. The current, as well as the current-load curve, exhibits a different behavior depending on the scaling of the colored noise strength. This archetypal correlation ratchet is capable of...

Gametes, embryos and the life in being: the impact of reproductive technology on the rule against perpetuities.

As the twenty-first century begins, changing technology is testing old rules of property law. In this Article, the author discusses the effect of modern technology on the Role Against Perpetuities. This discussion includes the arguments for and against recognition of the embryo as a life in being, as well as suggestions for legislative solutions to this issue.
