Emerging peer-to-peer applications require efficient group communication. However, current techniques for group communication are not optimal for peer-to-peer networks, which do not have group communication methods themselves. This paper presents the novel multiring topology, which is designed to meet requirements of high performance group communication in peer-to-peer networks. It improves dat...

In this paper, we study the application of random network coding in peer-to-peer (P2P) networks. The system we analyze is based on a prototype called Avalanche proposed in [8] for large scale content distribution on such networks. We present the necessary techniques for analyzing the system and show that random network coding provides the system with both maximum bandwidth efficiency and robust...

Lending officers (LOs) assess loan applications under conditions characterized by shifts in economic climate, wavering public credibility for banks and greater industry regulation. This paper examines the extent to which, in such an economic environment, the LOs’ assessment of commercial loan applications may be defensive, and, if so, which mechanisms that may trigger defensive loan assessment ...

Music piracy, which is often engaged in by college students, constitutes illegal behavior under the U.S. Copyright Act and, arguably, has a negative impact on the music industry. Based on prior research and a focus group conducted for this research, Gottfredson's low self-control and Sykes and Matza's techniques of neutralization along with the concept of drift, and rational choice theory have ...

Active XML (AXML) is an extension of XML to exploit the powerful computation ability of peer-to-peer network and Web services technologies. AXML is considered a distributed XML DBMS which extends the capability of XML by embedding intensional XML data inside XML documents. The management of intensional XML and XML data together in XML documents raises issues such as representation for intension...

Many emerging interactive and collaborative applications use the peer-to-peer paradigm nowadays. In every-day life peer-to-peer meetings of small groups are dominant, e.g. for business talks. Confidentiality is of primary concern in this context to provide group privacy. To assure confidentiality the partners have to agree upon a secret group key for encrypting their communication. This require...

this research study aimed at investigating whether using peer-provided feedbacks rather than teacher-provided comments would result in any significance difference in iranian english undergraduate students’ ability in writing. in so doing, based on a pretest (an opt & a writing exam), 40 subjects were assigned to two homogeneous groups of equal number the subjects in the control group received m...

Semantic People Tagging is an Enterprise 2.0-style approach to making expertise and individual capabilities transparent. By combining it with a collaborative ontology editor and thus the possibility to construct a shared vocabulary and understanding, it can be a supplement for cumbersome competence management, or expert finder solutions, which lack acceptance among employees, and suffer from ou...

We explore authenticated group key agreement in data-sharing Peer-to-Peer networks. We first propose a novel password-based authenticated group key agreement protocol with key confirmation. We present a formal statement of its security in a variant of the Bresson et al. security model adapted for the password-based setting. A discussion of the limitations of our protocol in the case where the g...
