The simultaneous consideration of various notions (practice, procedure, prescribed task, effective task, task space, task search, task, method, activity) shows that the task accomplishment cannot be discussed at a general level, as classical approaches do. Rather, this paper points out the importance to distinguish the task definition and the task realization because the former is mainly static...

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...

In contradiction to stimulus-response- (S-R-) translation bottleneck models of dual-task control, stimulus processing in a primary task is affected by its compatibility with the response in a secondary, later performed task (Hommel, 1998a)- an indication of parallel S-R translation. Here we show that this backward-compatibility effect is independent of working-memory load, whether this is induc...

The present study aimed at investigating the relationship between organizational trust and organizational commitment in staff. Eighty-four persons from 101 staff of department of Sports and Youth in the province of Mazandaran responded to two questionnaires of “Organizational Trust Inventory (OTI)” developed by Shockley-Zalaba, Ellis, and Winograd (2000) and “Organizational Commitment Questio...

In this paper, we review the literature on efficient task scheduling on multi-core system. The number of cores on one chip are increasing very rapidly. For achieving high performance without more power consumption and without heating up the system, multi-core processing technology is used. In addition for fully utilization of system resources in more efficient way task scheduler are developed, ...

objectives: the present study aimsed to examine the reliability of forceplate parameters under both single and dual task conditions and in different levels of postural difficulty. methods & materials: the healthy elderly+65, were assessed with aone-week interval, with a random combination of three levels of postural difficulty (i.e., standing on a rigid surface with eyes open, standing on a rig...

This paper identifies new challenges for knowledge-based planning research by examining the relationship between plans and procedures. Procedures are plan-like data structures containing variables. Typically, one procedure abstracts many plans. Just prior to or during execution, a procedure is selected and instantiated fully according to the prevailing situation. Procedures can be constructed u...
