This research examines how teens learn L2 vocabulary when affected by different types of oral corrective feedback during a controlled classroom interaction. The study employed post-test design. Pre-Intermediate teens ESL learners (N 30) in an institute were categorized into three groups: prompts, recasts, and control. In the treatment stage, a four step vocabulary activity was provided to promp...

As part of the Stanford Digital Libraries Project, we have prototyped a novel architecture for security and access control in heterogeneous, networked environments. Conceptually, this architecture recasts security issues from an “information access” metaphor into a “relationship management” framework and uniformly applies a contracting model. Architecturally, it introduces a “network-centric” d...

While it remains a central reference for work in computational creativity, Boden’s exploration/transformation model can be interpreted as having different meanings at the application level. As a result, programmers developing creative systems may have difficulty in realising the theory’s practical value. The paper develops a formalisation which recasts the key elements in quantitative terms whi...

The Shell model Monte Carlo (SMMC) method [1] was developed as an alternative to direct diagonalization in order to study low-energy nuclear properties. It was successfully applied to nuclear problems where large model spaces made diagonalization impractical. One calculates the thermal canonical expectation values of observables of few-body operators by representing the imaginary-time many-body...

The current study examined the impact of video-based conversational interaction on the longitudinal development (one academic semester) of second language (L2) production by collegelevel Japanese English-as-a-foreign-language learners. Students in the experimental group engaged in weekly, dyadic conversation exchanges with native speakers in the US via telecommunication tools, wherein the nativ...
