aim: it seems that positive outcomes resulting from the autonomy in the job, is dependent on a number of factors. autonomy means the interdependence and freedom of staff in planning and organizing work and it has different levels. the aim of current research is to investigate the role of task reflection in relation of autonomy and skill utilization. method: the research sample consisted of 324 ...

objectives: this study aimed to identify elderly fallers and non-fallers by balance test under dual tasks conditions. methods & materials: this study was an analyze-comparative study. subjects were from three park of tehran. subjects were 20 older adults with outhistory of falls (aged 75.95±6.28 years) and 21 older adults with a history of 2 or more falls in the previous one year (aged 72.50±7....

one of the most problematic areas in foreign language learning is collocation. it is often seen as arbitrary and an overwhelming obstacle to the achievement of nativelike fluency. current second language (l2) instruction research has encouraged the use of collaborative output tasks in l2 classrooms. this study examined the effects of two types of output tasks (editing and cloze) on the learning...

Past studies suggested that decision support systems (DSS) must be an “enabling” system aiming to enhance users’ capabilities and to leverage their skills and intelligence. This suggests that users be the center of DSS and users’ characteristics be an important factor of explaining their DSS acceptance behavior. Since DSS are aimed to work in semi-structured and unstructured task environment, p...

Task analysis can be defined as the study of what a user is re q u i red to do, in terms of actions and/or cognitive processes, to achieve a task objective. The idea is that task analysis provides some stru c t u re for the description of tasks or activities, which then makes it easier to describe how activities fit together, and to explore what the implications of this may be for the design of...

A substantial body of research has highlighted the effects of experience on individual performance in groups. However, the challenges individuals confront after moving between groups require the adoption of more finely grained categorizations of experience to understand how they will help or hinder performance in novel group environments. This article develops a distinct form of experience here...

Workflow management systems (WFMS) coordinate execution of multiple tasks performed by different entities within an organization. In order to coordinate the execution of the various tasks in a workflow, task dependencies are specified among them. These task dependencies are enforced during the normal execution of the workflow. When a system crash occurs some tasks of the workflow may be committ...

Stigmergy is usually used to model semantically simple problems such as routing. It can be applied to more complex problems by encoding them in the stigmergic environment. We demonstrate this approach by showing how stigmergic agents can plan over a hierarchical task network, specifically a resource-oriented dialect of the TÆMS language.
