In real-world peer-to-peer applications, the scalability of data lookup is heavily affected by network artifacts. A common solution to improve scalability, robustness and security is to increase the local properties of nodes, by clustering them together. This paper presents a framework which allows for the development of distributed applications on top of interconnected overlay network. Here, m...

Community violence is recognized a significant public health problem. However, only a paucity of research has examined risk factors for community violence exposure across domains relevant to adolescents or using longitudinal data. This study examined youth aggressive behavior in relation to community violence exposure among a community epidemiologically defined sample of 582 (45% female) urban ...

Overlay networks are a technique whereby application developers create virtual customized networks on top of physical networks. Recent implementations of peer-to-peer applications such as file sharing and VoIP have increasingly meant that overlay networks have almost become ubiquitous. As a result, future overlay networks will increasingly coexist on the same node. A number of middleware framew...

Affiliation with weight conscious peer groups is theorized to increase thin-ideal internalization through socialization processes. However, selection effects could contribute if genetic and/or environmental predispositions lead to affiliation with weight conscious peers. Co-twin control methodology was used to examine socialization and selection effects in 614 female twins (ages 8-15) from the ...

This study examined functional outcomes for children with ADHD by comorbidity status. Children with ADHD (5-13 years) were recruited from 21 pediatric practices and followed up 12 months later (n = 199). Parent and teacher-reported baseline and 12 month surveys measured peer problems, daily functioning, quality of life (QoL), parent mental health, and family QoL. The Anxiety Disorders Interview...

background: reproductive health problems affect youths in all countries. there is an urgent need to enhance youths reproductive health services to provide a healthy life for this group. in this regard, the present study aimed to evaluate the reproductive health peer education program based on the opinion of university students.   methods :this interventional study was conducted in qazvin univer...

The peer-to-peer (P2P) system has prevailed on the Internet. The old client-server architecture is gradually becoming unable to satisfy users’ various requests and deal with the heavy loading of networks. Many applications adopt P2P architecture to provide more flexible and efficient service. However, P2P systems are not flawless. The anarchic property of P2P systems keeps participant behaviour...

evidence-based medicine is becoming an important s of human life span, which crucial developmental processes occur. since peers play a critical role in the psychosocial development of most adolescents, peer education is currently considered as a health promotion strategy in adolescents. peer education is defined as a system of delivering knowledge that improves social learning and provides psyc...

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 ...
