Previous research has suggested that similar to other age-related declines in language production, the ability to produce the correct spellings of words decreases in old age (e.g., Abrams & Stanley, 2004; MacKay & Abrams, 1998; MacKay, Abrams, & Pedroza, 1999; Stuart-Hamilton & Rabbitt, 1997). However, aging alone does not predict spelling deficits. For example, spelling ability interacts with ...

The foraging behaviour in web building spiders involves: (1) placing the web in the habitat, (2) constructing the web, (3) attacking prey entangled in the web, and (4) ingesting prey (Leborgne et al., 1991). Foraging theory suggests that organisms should exhibit foraging behaviour that optimizes the relationship between benefits and costs (Schoener, 1971; Pyke et al., 1977). The two major benef...

Populations of coupled oscillators may exhibit two coexisting subpopulations, one with synchronized oscillations and the other with unsynchronized oscillations, even though all of the oscillators are coupled to each other in an equivalent manner. This phenomenon, discovered about ten years ago in theoretical studies by Kuramoto and Battogtokh [1], was further characterized by Abrams and Strogat...

This essay discusses cryptographic protection of information confidentiality and integrity as that information passes from one point in space-time to another. More recent uses of cryptography , such as authentication and nonrepudiation are also discussed. The essay begins with an introduction of these ideas, including some basic examples, then proceeds to the definition of a cryptographic syste...
