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 ...

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.

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...

according to a basic prediction made by the revised hierarchical model (rhm,kroll & stewart, 1994), there is no l2 conceptual connection at the beginning stages of language learning as l2 learners mostly rely on l1 conceptual connections to retrieve the meaning of the l2 words.with increasing proficiency, however, there would be a direct access from l2 to the conceptual system. available litera...

As computers have become more powerful, the simulations and data processing applications that use them have become resource hungry, and, at the same time more complex. The complexity of simulations has increased in terms of the number of dimensions (from 1D to 2D to 3D), the set of equations being simulated (from one equation, to multiple equations in one domain, to multiple equations in multip...

The purpose of this qualitative exploratory study was to identify factors that influenced prospective and experienced secondary level science teachers’ reasoning as they evaluated or selected tasks to formatively assess their students’ understanding of scientific concepts. The analysis of the coded written responses revealed two categories of factors that influenced the teachers’ reasoning: (1)...

This paper follows the scenarios and task models debate by reviewing the contributions of task modelling and scenario based approaches from a cognitive perspective. A framework of cognitive affordances is introduced to discuss the merits and limitations of each approach. An extension of the modelling theme, generic task models, is proposed to augment the contribution of knowledge reuse to the d...

In this paper we present our first participation at RepLab Campaign. Our work is focused in two contributions. The first one is the use of an IR method to address Polarity and Filtering tasks. These two tasks can be seen as the same problem: to find the most relevant class to annotate a given tweet. For that, we applied a classical IR approach, using the tweet content as query against an index ...

This case study investigated how five novice teachers of French went about implementing tasks. In particular, the investigation aimed at finding out about implementational demands that imposed challenges for the teachers and how they coped with these challenges. The study also looked at the complementary relationship between implementational demands and task design factors and how these impact ...
