Web 2.0 technologies are having a considerable influence on the learning industry. Constructivist learning processes, such as collaborative writing, have emerged as a result of the development of Web 2.0 technologies. We define the term “mandatory collaborative writing” to describe a writing task where the group has a firm deadline. This article focuses on(More)

Constructivist learning mechanisms such as collaborative writing have emerged as a result of the development of Web 2.0 technologies. We define the term mandatory collaborative writing to describe a writing activity where the group has a firm deadline. Our study focuses on how a wiki can fully support mandatory group writing. The motivation of this design(More)
This study posits Blogs and Podcasts can be used to persuade students in one school to have more sense of community among their group. We designed and developed the WordPress MU based artifact, SISATSpace, to extend students' conversations and foster academic and friendly relationships. SISATSpace might be consider as a persuasive tool, medium, and social(More)
This paper explores the design and evaluation of a trust model to establish trust management in an open source collaborative information repository for an emergency response environment. The proposed model is an instantiation of the SECURE framework and it is based on the characteristics of trust defined by recent information systems research. Evaluation of(More)
RSA is the most well-known public key cryptosystem. The security of RSA is based on the difficulty of factoring the modulus which is the product of the two large prime numbers. If the modulus is factorized, RSA is broken. VFactor is a new factorization algorithm which can factorize the modulus faster than Fermat's Factorization algorithm (FFM) and Trial(More)
We propose a method to decrease processing time for two factorization algorithms. One is Modified Fermat Factorization Version 2 (MFFV2) modified from Modified Fermat Factorization (MFF). The other is Modified Non - sieving Quadratic Sieve Version 2 (MNQSV2) modified from Modified Non - Sieving Quadratic Sieve (MNQS). A key concept of this method is to(More)
