Raising information security awareness in digital ecosystem with games - a pilot study in Thailand

Success of digital ecosystem depends on a reliable supporting infrastructure that offers and transports services and information thereby empowers the business system to function properly. This implies the utmost importance to maintain the reliability, confidentiality and integrity of the network and communication systems. This paper reports an initial pilot study on the use of a simulation game called CyberCIEGE for raising the awareness and knowledge on Information Security among a small group of Thai students. The paper provides an overview of the software, the experiment and results, and, a discussion on the next phase of this proposed projec

Biaxial nematic phases in amphiphilic systems

The formation of biaxial nematic phases in mixtures of surfactants and water is discussed. Emphasis is given to experimental data that confirm the existence of a biaxial nematic phase. Some new microscopic observations and birefringence measurements are reported. Biaxial nematic phases were observed in two systems that have, in addition, two uniaxial nematic phases. The general features of the phase transitions involving these nematic phases are theoretically analyzed on the basis of a Landau expansion. Specific relations for the order parameters are derived that compare favorably with the experimental results
