This article examines the relationships among task goal clarity, task significance, and individual-level task performance. While both goals and task significance are important in extant public-management research, a theoretical integration of the variables is needed. This study makes the theoretical contribution of explaining how these variables might work together in a public organization. In ...

The paper presents an ACT-R model of task switching, which implements flexible mechanism of control over task rules, that adapts to the level of task change predictability. In predictable task switching situations, the model loads relevant task rules into an easily accessible focus of attention (simulated with an ACT-R goal buffer). However, when tasks change randomly, such strategy would lead ...

While a software process is being exe cute d,many errors and problems occur which require to r econsider previously exe cute dprocess steps. In order to handle fe edback in a process management system, several requir ementsne ed to be addr essed: adaptability, human intervention, impact analysis, change prop agation, r estor ation of the work c ontext, and traceability. F eedback management in ...

Recent evidence suggests that interleukin-1beta (IL-1beta), which was originally identified as a proinflammatory cytokine, is also required in the brain for memory processes. We have previously shown that IL-1beta synthesis in the hippocampus is dependent on P2X(7) receptor (P2X(7)R), which is an ionotropic receptor of ATP. To substantiate the role of P2X(7)R in both brain IL-1beta expression a...

It is well recognised that task analysis and modelling are complementary to object oriented software development. While the latter has gained widespread use, the adoption of the former is still rare in industry. We argue that while good methodologies are important, they are not sufficient by themselves to ensure their rapid adoption. What is also needed are tools which will mediate the implemen...

In this paper we evaluate the Parallel-Horus parallelization strategy, and propose some approaches for further optimization. Also, we compare the Parallel-Horus approach with other strategies described in the literature. Furthermore, we investigate if adding automatic task parallelization is possible, and if this can be done in a user-transparent way.

The working style of virtual R&D team is becoming more and more popular, so lots of researchers concern about the performance of virtual R&D teams. Shared mental model (SMM) is a concept in psychology which is defined as a common thinking style developed by similar experience and individual mental models. In this paper, we consider two types of SMM, which are task-related SMM and member-related...

objectives: the aim of this study was to identify the role of attentional process in postural control using choice reaction time task while changing the visual and proprioceptive cues under difficult balance task (standing on one-leg). methods: this cross-sectional study was conducted by participating 20 young people (22.75±2.29). each subject performed one-leg standing as balance task for each...
