As the number of applications available on the World Wide Web (WEB) increases at a rapid speed, an enormous number of resources become available to the general public. These resources offer information and services in a variety of domains but are often difficult to use due to their idiosyncratic domain and interaction models. In this paper, we discuss a multi-agent architecture for integration ...

Spatial skills predict students’ success in STEM domains. This paper aims to better understand the difficulties of students with low spatial skills in using interactive graphical representations. I present a mediation analysis with test and log data from 117 students who worked with an intelligent tutoring system for chemistry. The analysis is based on (1) a knowledge component model that descr...

BACKGROUND Although historically tuberculosis (TB) has been associated with poverty, few analytical studies from developing countries have tried to: 1. assess the relative impact of poverty on TB after the emergence of HIV; 2. explore the causal mechanism underlying this association; and 3. estimate how many cases of TB could be prevented by improving household socioeconomic position (SEP). M...

This article is concerned with the social organization of mediation in learning environments. It seeks to further articulate the sociocultural notion of mediation in sociointeractional terms, combining insights from the sociocultural approach to cognition and the microinteractionist, especially ethnomethodological approach to social activities.Amicroanalysisofmediation incommunicative2nd-langua...

(2011) "Knowledge processes, knowledge-intensity and innovation: a moderated mediation analysis", Journal of Knowledge Management, Purpose – The purpose of this paper is to examine innovation from a knowledge-based view by exploring the effect of knowledge processes and knowledge intensity on innovation performance. Design/methodology/approach – First, a theoretical model of the connections bet...

Resting state fMRI (rs-fMRI) has recently been considered as a possible complement or alternative to task-based fMRI (tb-fMRI) for presurgical mapping. However, evidence of its usefulness remains scant, because existing studies have investigated relatively small samples and focused primarily on qualitative evaluation. The aim of this study is to investigate the clinical usefulness of rs-fMRI in...

Presented is the vision of the authors on how diverse web services may be composed, mediated by dynamic task coalitions of agents performing tasks for service requestors. The focus and the contribution of the paper is the proposal of the layered web service mediation architecture. Middle Agent Layer is introduced to conduct service request to task transformation, agent-enabled cooperative task ...

Rail inspection is an essential task in railway maintenance and is periodically needed. Inspection is manually operated by trained human operator walking along the track searching for visual anomalies. This monitoring is unacceptable for slowness and lack of objectivity. This paper deals with a patented Visual Inspection System for Railway maintenance, devoted to different tasks. Here, its Rail...

this study explored the effect of contrastive phrase resynthesis instruction ongaining the teachability hypothesis stages in self-paced versus time-constrained oralproduction and recognition. three groups (i.e., 23 learners) of high beginner femalelearners in an english language institute were randomly selected from a cohort oflearners. one group received contrastive metalinguistic instruction ...

this study was an attempt to investigate the comparative impact of two types of teaching approaches, namely content-based (cbi) and task-based (tblt) instruction on the reading comprehension of iranian efl learners. for this purpose, sixty intermediate students from a pool of eighty five students studying at a private language school were chosen using a piloted pet. the students were then rando...
