As cyberschooling options expand, it is vital that we understand the nuances of these particular learning opportunities. Because little research exists on leaders of K-12 cyberschools, this exploratory case study had two purposes. We first examined how 18 cyberschool leaders in the United States obtained their position. Second, we explored the perceptions of cyberschool leaders regarding the di...

Here we present a single-cell-based model of cell-cell interactions in a growing yeast colony. We examine the influence of multiple factors on the colony morphology and switch to a foraging growth behavior. We find that the cell-growth inhibition by neighboring cells along with polar division growth patterns are the most significant factors driving the exploratory behavior of a colony.

Purpose This study introduces a method based on link analysis to investigate the structure of the R&D support infrastructure associated with science parks in order to determine whether this webometric approach gives

We propose a new type of input for mobile devices by sensing forces applied by users to device casings. Deformation of the devices is not necessary for such “force gestures” to be detectable. Our prototype implementation augments an ultra-mobile PC (UMPC) to detect twisting and bending forces. We describe examples of interactions using these forces, employing twisting to perform application swi...

This work analyzes a case of computer-supported scripted collaboration, focusing on how students’ self-organization affected the actual collaboration script during script run-time. Two groups of students studied learning material using a web environment designed for supporting case-based learning. The first group followed a non-scaffolded individual mode of study while students in the second gr...

In this paper, we describe the result of the first part of a continuous effort to identify and validate factors influencing sociability of online social software. The concept of sociability was first refined and then a series of interviews were carried out to gain understanding of how users use social software to facilitate their social interactions and social relationships maintenance. We also...

We present work towards a spoken-dialogue embodied companion system that behaves in a socially cooperative fashion, i.e., being attentive to communicative and social cues emitted by the user, inferring internal cognitive, affective and interactional states, and reciprocating with appropriately adapted behavior. It is argued that this capability is vital for fostering cooperative, effortless, an...

This study reports an intensive, exploratory study of a single, protracted conflictual interaction involving all four members of a family. Within the larger interaction, there were four subinteractions. Because of space limitations, only the central conflictual subinteraction will be described. This interaction involved three of the four family members: the father and two daughters. The two chi...

Three alternative approaches to the modeUing of urban planning-processes are reviewed in this paper. These focus attention respectively on their sequential properties, their contextual elements, and the nature of the interactions between the actors involved. The findings of the review indicate that the three approaches reflect separate bodies of theorising and experience which sharpens the cont...

iSTART is an intelligent tutoring system (ITS) designed to improve students’ reading comprehension. Previous studies have indicated that iSTART is successful; however, these studies have also indicated that students benefit most from long-term interactions that can become tedious and boring. A new game-based version of the system has been developed, called iSTART-ME (motivationally enhanced). I...
