Related to nonsynchronous: synchronising


(sing′krŏ-nīz″) [Gr. synchronizein, to be contemporary with],


To coordinate the timing of two or more events or processes. In electrical cardioversion, for example, a shock to the heart is delivered when an R wave is detected on a cardiac monitor. Synchronized shocks are used to treat rhythms such as atrial flutter, atrial fibrillation, or supraventricular tachycardia, in which QRS complexes are recognizable. In these arrhythmias, unsynchronized shocks might induce ventricular fibrillation.

Bergstrom and Sauer (1986) felt double captures resulted from "random nonsynchronous encounters" at traps with increased springing tension, and suggested the following criteria needed to be met in double captures to infer social traveling: (1) no interspecific captures; (2) equal springing weight in traps with single and double captures; (3) nonrandom age-sex ratios; (4) recaptures of the same pairs; (5) no adult-juvenile pairs; and (6) proportion of double captures is independent of population density.

The importance of nonsynchronous trading occurs because it biases the moments and co- moments of an asset's returns, such as the coefficients of the mean, variance, covariance, beta, autocorrelation and cross-correlation.
A closely related phenomenon that buttresses this interpretation of serial correlation in hedge fund returns is the "nonsynchronous trading" effect, in which the autocorrelation is induced in a security's returns because those returns are computed with closing prices that are not necessarily established at the same time each day (see, for example, Campbell, Lo, and MacKinlay 1997, chap.
