The bulk of research within the interactionist framework seems to be consensually pointing to the beneficial effects of interaction in SLA. However, few studies have investigated the role of training in providing and perceiving interactional feedback, especially among young learners. This study probed the effects of training prior to engagement in interaction in case of young learners acquiring...

There has been a significant body of research conducted into various structured and unstructured overlay network protocols. Both paradigms have advantages for specific application domains and researchers are beginning to examine the benefits of using hybridized systems. We hypothesize that resource awareness and adaptation are essential to the efficient exploitation of the resources available o...

This study examined the influence of peers in meeting DSM-IV symptom criteria for an internalizing disorder in adolescents exposed to Hurricane Georges. Participants included a representative community sample of 905 youth (n = 476 boys) ages 11-17, residing in Puerto Rico. Data were gathered on hurricane exposure, symptoms of internalizing disorders, peer social support, peer violence, and peer...

Today, Peer-to-Peer applications are predominant on the internet when considered in terms of its tra c consumption. However apart from Skype, their commercial success is still very limited. This is due to the di culties faced when trying to implement crucial functionality such as accounting and charging without violating the Peer-to-Peer paradigm. A fully decentralized accounting scheme based o...

This study investigates the effect of homogeneous and heterogeneous peer interaction on the development of Iranian EFL learners’ writing skill. Sixty female students of TEFL participated in the study. The participants were divided into two groups based on their English proficiency test scores. The homogeneous group consisted of 14 participants paired with partners with similar English proficien...

In this paper we propose a peer-to-peer support approach that we call structural awareness support. The structural awareness aims to support the communication that takes place in virtual learning communities. Its emphasis is on revealing the group structure to its participants in order to promote collaborative interactions. This support has been implemented on a forum type tool called Mailgroup...

In today’s society, an increasing number of personal and business interactions occur remotely. Much of this collaboration takes place online via the Internet. While not every message may need to be secure, some will, creating a concern as to how one individual can trust another, especially if they have never met. This paper presents an original trust model that can support secure adhoc collabor...

There has been a recent push in extraction of 3D spatial layout of scenes. However, none of these approaches model the 3D interaction between objects and the spatial layout. In this paper, we argue for a parametric representation of objects in 3D, which allows us to incorporate volumetric constraints of the physical world. We show that augmenting current structured prediction techniques with vo...

One of the most popular P2P applications on the internet is P2P media streaming. Finding nearby peer over the internet is challenging job in live media streaming because it is time constrained application and nearest neighbors have to discover as quickly as possible. Objective of media streaming is low latency, QoS and scalability. For applications like Gnutella, finding the nearest peer can re...
