Second, for independent unitary tasks, we provide an optimal scheduling algorithm where the objective is to maximize the reliability subject to makespan minimization.
Although it is commonly believed that accounting and performance management are relatively straight-forward and unitary tasks, authors have highlighted that in fact there are many different logics and ways to understand, operationalize, and motivate them, resulting in very different varieties of accounting regimes and consequences [ 33, 34].
One of the conditions they identified was "Unitary, nondivisible, simple tasks need to be completed, such as the learning of specific facts or the acquisition or the performance of simple skills" (p. 370).
Integration of information streams into a unitary representation is an important task of our cognitive system.
Sato et al. [ 5] trained one adult female chimpanzee on a matching-to-sample task in which unitary and separated rectangles appeared as stimuli.
In particular, RT variability across a wide variety of neuropsychological tests was recently reported to be the best discriminator between ADHD cases and controls, with principal components analysis suggesting that RT variability across tasks forms a unitary construct [ 55].
As a result, there is the possibility that subjects, rather than splitting their attention, may have performed the task by elongating a unitary spotlight into such a formation as to encapsulate the regions where the targets were expected to appear, while remaining spatially contiguous through the fixation point.
The best known example of unitary theory for the control of hybrid tasks can be derived from the equilibrium point hypothesis (EPH) [27] [29], which views posture as the biomechanical consequence of the interaction among the spring-like behavior of muscles and reflexes and movement as the transient from an equilibrium state to another.
However, in our examples, we have found that a unitary scale coefficient is adequate to perform the task.
First, measures of intra-individual variability best discriminated between the ADHD and control groups; second, intra-individual variability appeared to be a unitary construct in ADHD (individuals with high variability on one task tended to have high variability on other tasks).
