An implicit assumption of trust in the participants is at the basis of most Peer-toPeer (P2P) networks. However, in practice, not all participants are benign or cooperative. Identifying such peers is critical to the smooth and effective functioning of a P2P network. In this paper, we present the ROCQ mechanism, a reputation-based trust management system that computes the trustworthiness of peer...

In this experimental study, we made an attempt to examine gender-related peer influences on childhood fear. Nine- to 12-year-old boys and girls were provided with ambiguous and positive information about novel animals and then asked to provide a subjective fear rating of the animals under two conditions: fear of one animal was assessed individually by the child on its own, whereas fear of the o...

Fueled by the popularity of firms such as Airbnb and Uber, the sharing economy, otherwise referred to as the collaborative economy or peer economy, has recently gained increasing attention among practitioners and academics. In the sharing economy,3 new ventures develop and deploy digital platforms to enable peer-to-peer sharing of goods, services and information. The underlying proposition of s...

Instructors and students would benefit more from computersupported peer review, if instructors received information on how well students have understood the conceptual issues underlying the writing assignment. Our aim is to provide instructors with an evaluation of both the students and the criteria that students used to assess each other. Here we develop and evaluate several hierarchical Bayes...

This research was designed to investigate the effects of two different types of learning modalities, namely Meta-cognitive Prompting and structured peer interaction on intermediate EFL learners’ collaborative writing. For this purpose, 90 learners of total number of 120 intermediate learners studying at Kish English language school were chosen first for homogenization prior to the study. In ord...

INTRODUCTION As today's healthcare model moves toward more streamlined and corporate industrialism, it is our responsibility, as doctors, to ensure the integrity of medicine's foundation in professionalism. The erosion of professional values not only creates a climate of animosity, but reverberates negatively to impact the development of students, who model their behaviour after those they most...

SETTING Two managed care adult primary care clinics. PARTICIPANTS A t...

among structured peer-to-peer systems, chord has a general popularity due to its salient features like simplicity, high scalability, small path length with respect to network size, and flexibility on node join and departure. however, chord doesn’t take into account the topology of underlying physical network when a new node is being added to the system, thus resulting in high routing latency an...

abstract— peer-to-peer ( p2p ) systems have been the center of attention in recent years due to their advantage . since each node in such networks can act both as a service provider and as a client , they are subject to different attacks . therefore it is vital to manage confidence for these vulnerable environments in order to eliminate unsafe peers . this paper investigates the use of genetic ...
