The notion of a compensation is widely used in advanced transaction models as means of recovery from a failure. Similar concepts are adopted for providing “transaction-like” behavior for long business processes supported by workflows technology. Generally, designing a compensating task in the context of a workflow process is a non-trivial job. In fact, not every task is compensatable. This work...

Task-related motion is a major source of noise in functional magnetic-resonance imaging (fMRI) time series. The motion effect usually persists even after perfect spatial realignment is achieved. Here, we propose a new method to remove a certain type of task-related motion effect that persists after realignment. The procedure consists of the following: the decomposition of the realigned time-ser...

this work supports the effectiveness of the employment of communication strategies for bet-ter and more efficient communication. communication strategies varies as a function of dif-ferent factors such as personality traits, pedagogical setting, l2 context, etc. the present re-search aimed at delving into the relationship between shyness, task nature and the frequency and type of communication ...
