The rationale of co-rank • The co-rank tool is designed to facilitate the grading process in Massive Open Online Courses (MOOCs). • Goal: implement an efficient grading system to evaluate the performance of the students. • Problem: the number of students attending a course is huge, while the number of available professional graders is limited. • Suggestion: peer grading; each student acts as a ...

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 ...

Existing measures of peer pressure and conformity may not be suitable for screening large numbers of adolescents efficiently, and few studies have differentiated peer pressure from theoretically related constructs, such as conformity or wanting to be popular. We developed and validated short measures of peer pressure, peer conformity, and popularity in a sample (n= 148) of adolescent boys and g...

Sharing content such as scientific papers or multimedia data in locally distributed organisations or between a group of co-operating users still poses a couple of problems. Existing systems like centralized client-server solutions and distributed peer-to-peer applications both suffer from their characteristic disadvantages. Centralized systems on the one hand have advantages in their good manag...

Peer review, the process of improving the quality of work done by a peer of approximately equal caliber, is posited to be an effective educational tool and learning process. Unfortunately, many students participating in peer review lack confidence in the value of their feedback or experience difficulty maintaining interest in another student’s work, thus tending to create feedback that is super...

Sexual content in teenagers' media diets is known to predict early sexual behaviour. Research on sexual content has not allowed for the social context of media use, which may affect selection and processing of content. This study investigated whether sexual media content and/or contextual factors (co-viewing, parental media restrictions) were associated with early sexual behaviour using 2251 14...

The epistemology of disagreement concerns the normative question of how you ought to revise your beliefs in a very specific epistemic context. Imagine that you and a peer form an opinion in isolation about whether P in response to mutually shared evidence, and you take your peer to be just as reliable as you about matters of this kind. How are you to respond should you subsequently discover tha...
