There is an extensive literature on task modelling related to the design of computer systems. Task analysis and task modelling have been widely recognized as central components in human-centred approaches. The aim of this paper is to report on some results of a worldwide survey about actual practices of task descriptions languages (TDL) in SIGCHI community. Results suggest that academic TDL are...

Many-Task Computing (MTC) is a widely used computing paradigm for large-scale task-parallel processing. One of the key issues in MTC is to schedule a large number of independent tasks onto heterogeneous resources. Traditional task-level scheduling heuristics, like Min-Min, Sufferage and MaxStd, cannot readily be applied in this scenario. As most of MTC tasks are usually fine-grained, the resour...

On construction jobsites, digital cameras are inexpensive devices that are widely used as an effective site observation method (Oglesby et al. 1989; Kim and Bai 2009). This opens the door for conducting scientific method studies on complex operations for productivity improvement through examining recorded videos. However, tedious manual reviewing is currently still required to extract productiv...

In studies of visual attention, and related aspects of cognition, race (continent/s of ancestry) of participants is typically not reported, implying that authors consider this variable irrelevant to outcomes. However, there exist several findings of perceptual differences between East Asians and Caucasian Westerners that can be interpreted as relative differences in global versus local distribu...

We present an extensive investigation (24 experiments) of a new case of prosopagnosia following right unilateral damage, GG, with the aim of addressing two classical issues: (1) Can a visual recognition impairment truly be specific to faces? (2) What is the nature of acquired prosopagnosia? We show that GG recognizes nonface objects perfectly and quickly, even when it requires fine-grained anal...

the necessity and importance of teaching pragmatics has come to light by many researchers (e.g. rose & kasper, 2001). due to the consensus over the need to teach pragmatic competence, the main issue now centers on the question of how we should teach this competence in the most effective way. consistent with this line of research, the present study aimed to investigate the effectiveness of d...

In Experiment 1, a normal adult population drawn from a remote culture (Himba) in northern Namibia made similarity matches to [Navon, D. (1977). Forest before trees: The precedence of global features in visual perception. Cognitive Psychology, 9, 353-383] hierarchical figures. The Himba showed a local bias stronger than that has been previously observed in any other non-clinical human populatio...

In compound, hierarchical stimuli (also known as Navon figures), a Global Precedence Effect (GPE) can reliably be observed for both letters and non-letters. However, when presentation conditions sufficiently resemble those of reading, the GPE for letters has occasionally been found to disappear. We corroborate this effect in a study with a large group of participants. In addition, in-between tw...

This article reports on the findings of a study that investigated the impact of manipulating task performance conditions on listening task performance by learners of English as a foreign language (EFL). The study was designed to explore the effects of changing complexity dimensions on listening task performance and to achieve two aims: to see how listening comprehension task performance was aff...
