Both can be implemented by the stochastic gradient descent method for obtaining the de-mixing matrix. The MI is the contrast function for blind separation while the entropy is not. To justify the ME, the relation between ME and MMI is rstly elucidated by calculating the rst derivative of the entropy and proving that 1) the the mean-subtraction is necessary in applying the ME and 2) at the solution points determined by the MI the ME will not update the de-mixing matrix in the directions of increasing the cross-talking.

The two sections were taught by the same instructor and used the same instructional materials.

An online survey of two popular social networking sites, Facebook and MySpace, compared perceptions of trust and privacy concern, along with willingness to share information and develop new relationships. Members of both sites reported similar levels of privacy concern. Facebook members expressed significantly greater trust in both Facebook and its members, and were more willing to share identifying information. Even so, MySpace members reported significantly more experience using the site to meet new people. These results suggest that in online interaction, trust is not as necessary in the building of new relationships as it is in face to face encounters. They also show that in an online site, the existence of trust and the willingness to share information do not automatically translate into new social interaction. This study demonstrates online relationships can develop in sites where perceived trust and privacy safeguards are weak.

However, the manner in which website development actually takes place within organisations is still largely uncertain. In this paper, we examine the results of a research exercise involving case studies in 25 UK organisations aimed at investigating the way in which website development activities are currently carried out within UK organisations. In particular, this paper discusses the activities that are typically involved in website development projects, and the techniques and standards actually used for website development found within 25 organisations studied. One of the main ®ndings of the research project was that in 25 organisations studied there was only limited use of formalised website design techniques (mainly hierarchy charts and storyboards). However, roughly half of the organisations studied did use some form of website layout standards. Website documentation was only produced in roughly a third of the organisations and only roughly a quarter of the organisations had any formalised website testing procedures in place. q

This study investigates the determinants of an effective Website. A literature survey indicated that the major categories of determinants are: page loading speed, business content, navigation efficiency, security, and marketing/customer focus. The relative importance of each category was determined by counting the number of citations in the literature, and by soliciting the opinions of end users. The paper concentrates on experts' recommendations of how to create an effective Website from an e-commerce point of view.

As content on the web includes text, pictures, graphics, layout, sound, motion and, someday, even smell, making the right web content decisions are critical to effective web design. While an understanding of marketing strategies that attract visitors to websites is beginning to emerge, how to convert web surfers to repeat visitors is a less well-understood phenomenon. Through an empirical study, the authors develop the Website Preference Scale (WSPS) based upon the work in environmental psychology of Rachel Kaplan and Stephen Kaplan. The results identify underlying dimensions of effective website design and provide insight into site design characteristics, which may lead to a higher likelihood of revisit. D

This paper uses Kano's Model of Quality to develop a conceptual framework for investigating features in the web environment that satisfy basic, performance, and excitement needs of potential customers. The researchers classify features commonly used in the web environment according to Kano's three quality dimensions for products and services.

It was found that the tools of the Internet and Web were neither fully neutral nor fully specific to the websites' 'home' cultures. Cultural hybridisation and diffusion of innovation are suggested as alternative explanations.

Boosted by a wide range of new technologies, educational institutes all over the world are innovating their educational systems, in order to extend their services, to improve their performances or to reduce costs. The apparent self-evidence of educational innovation hardly prompts the educational staff to reflect on the very idea of innovation and its consequences. This paper treats the basic principles that support the phenomenon of technology-induced educational innovation. It aims to contribute to a better insight and understanding of its implications to anyone engaged in education. It also aims to effect a growing awareness of the premises on technology and to support the right attitude to realise improvements in practice. The paper goes into strategies of change, while discussing both substitutional and transformational strategies. It explains its supposed differences by referring to the philosophical frameworks of Jaspers, Heidegger and Borgmann. Starting from Borgmann's "devices paradigm", four principles for educational innovations are formulated, referring to the transparency and interactivity of educational technologies, the socio-cultural significance of products, the importance of values beyond efficiency and the political bias involved with technological innovation.
