The cumulative resource constraints of the resource-constrained project scheduling problem (RCPSP) do not treat the resource demands as geometric rectangles, that is, activities are not necessarily assigned to the same resource units over their processing times. In spite of this fact, most papers on resource-constrained project scheduling mainly in the motivation phase use a strip packing of re...

This study investigated the intervention of Zimmerman & Hutchins (2003) Information Synthesization vs. Visualization on Iranian Undergraduate ESP (Accounting) learners’ reading comprehension achievement across gender. 120 ESP University students majoring in Accounting in Iran participated in this study and were assigned to 4 homogeneous groups, 30 male and 30 female students in experimental gro...

Real-time volume data acquisition poses substantial challenges for the traditional visualization pipeline where data enhancement is typically seen as a pre-processing step. In the case of 4D ultrasound data, for instance, costly processing operations to reduce noise and to remove artefacts need to be executed for every frame. To enable the use of high-quality filtering operations in such scenar...

The traditional role of visualization in large scale social modeling projects has mostly been relegated to presentation and reporting. While these projects see the potential of communicating information visually, the visualization component has too often been considered as the final stage of a long process, sometimes as a lastminute add-on. The result is that these visualization components are ...

In this paper we show how the deployment of a lightweight note sharing system can restore the antique social vocation of annotations in the classroom. The system was designed for the classroom context and evaluated through a longitudinal study lasting for an academic semester and involving 20 participants, enrolled in a Master-level course in computer science. Three key findings emerged. First,...

We present Lyra, an interactive environment for designing customized visualizations without writing code. Using drag-and-drop interactions, designers can bind data to the properties of graphical marks to author expressive visualization designs. Marks can be moved, rotated and resized using handles; relatively positioned using connectors; and parameterized by data fields using property drop zone...

Some teachers adopt a blended learning model that combines traditional classroom teaching and an e-learning system. In this model, a teacher may teach the first few sessions in a classroom. After the students have established a general idea of the course, they can then proceed to on-line learning and interaction. This study aimed to discover the relationship between learning records and the lea...

Knowledge monitoring is an important metacognitive process which can help students improve study habits and thereby increase academic performance. Which is more useful in predicting test performance: knowing what you know, or knowing what you do not know? Two distinct constructs of knowledge monitoring calibration, sensitivity and specificity, were used along with the more traditional Gamma to ...
