分组P2P网络模型分包传输策略分析

Internet的飞速发展使对等网络(P2P)及其相关领域的研究成为热点,但是当前P2P网络的结构并不完善。文中介绍了几种P2P模型,并在综合这几种模型优点的基础上,针对P2P网络的动态特性提出了一种分组P2P模型。P2P的网络应用在正不断发展,P2P中的一个重要核心思想是分包传输,它所采用的分包算法对于我们开发P2P软件具有重要的参考价值.我们在本文中分析它的分包传输算法,并且结合参考Coolstreaming和沸点网络电视系统中的策略,对在P2P网络中进行视频、音频等多媒体流数据的传输的方法和性能进行分析。

同行专家的双向匿名审稿制度辨析

高校文科学报要改革审稿制度，严肃学术纪律和学术规范，就要逐步建立同行专家的双向匿名审稿机制，以杜绝关系稿、人情稿以及学术赝品，努力倡导甘于寂寞、潜心钻研、实事求是、严谨治学的学风。该制度有其特定内涵，但其优劣有待于实践的检验。     

Personal reflections: Barriers and strategies in increasing diversity in psychology.

In this article, six faculty and students of color who participated in a panel discussion at a symposium during the National Multicultural Conference and Summit of 2003 talk about the barriers they encountered and continue to encounter in their graduate training and places of employment. They also discuss strategies they found to be effective, enhancing, and positive and suggest other possibilities. The contributors describe their relationships with dominant-group and minority peers and talk about how issues of social class, disability, and sexual orientation as well as color have been part of their experience.

Data Distribution in a Peer to Peer Storage System

This article presents distributions for data storage in a P2P system. In peer to peer storage system we have to face a continuous stream of peer failures. So to insure data durability data are usually disseminated using a dispersal redundant scheme and a dynamic data reconstruction process is used to rebuild lost data. There is an important communication traffic to maintain data integrity. So, it is important to reduce the impact of this reconstruction process on peer. To minimize end user traffic according to the reconstruction process, distribution must take into account a new measure: The maximum disturbance cost of a peer. To begin with, we define a static distribution scheme which minimizes this reconstruction cost based on prime numbers theory. We compare this distribution with the random distribution, the most used in data distribution.This Project () is supported by the ACI GRID CGP2P and the ACI MD GDX.

Validity and reliability of scaffolded peer assessment of writing from instructor and student perspectives.

Although peer reviewing of writing is a way to create more writing opportunities in college and university settings, the validity and reliability of peer-generated grades are a major concern. This study investigated the validity and reliability of peer-generated writing grades of 708 students across 16 different courses from 4 universities in a particular scaffolded reviewing context: Students were given guidance on peer assessment, used carefully constructed rubrics, and were provided clear incentives to take the assessment task seriously. Distinguishing between instructor and student perspectives of reliability and validity, the analyses suggest that the aggregate ratings of at least 4 peers on a piece of writing are both highly reliable and as valid as instructor ratings while (paradoxically) producing very low estimates of reliability and validity from the student perspective. The results suggest that instructor concerns about peer evaluation reliability and validity should not be a barrier to implementing peer evaluations, at least with appropriate scaffolds. Future research needs to investigate how to address student concerns about reliability and validity and to identify scaffolds that may ensure high levels of reliability and validity.
