The negative impact of Internet use on adolescents has received much popular attention and has also become a popular research topic. How to induce adolescent players to change their attitudes toward online gaming is one of the most important issues in online gaming addiction. The present study is based on the less-leads-to-more effect of dissonance theory. Experimental research was conducted to...

A good publication record is one of the most important prerequisites of a successful academic career in IS. Despite the weight hiring and promotion committees place on it, the definition of a “good publication record” especially for junior researchers remains unclear. Indeed, is it better to have one A-publication or three B-publications? Does being the third author on an A-publication have a b...

Today, communication is main part of everybody’s life. Security is the most important issue in any communication. So we need a secured system to exchange data securely between users. For this purpose of security there are various techniques like cryptography, watermarking and steganography. Steganography is used to transmit information in covered form. In steganography we hide the presence of d...

Health informatics is a relatively new research area. Over the last decade or so, research in health information has been growing at a very rapid rate, as evidenced by the large number of publications. While this growth has been beneficial to the field, it has also made understanding the scope of the field more difficult. Consequently, it is difficult to answer questions such as how the researc...

Privacy protection on user context is one of the most important issues in ubiquitous and pervasive computing. This paper describes a new privacy protection approach that not only filters and reduces the granularity of context information to correct access level granularity, but also intelligently replace the filtered-out context information with the artificial context information considered app...

This paper is an expanded version of a paper presented at the EDEN conference, Vienna, June 2006. It expands the model of learner engagement in the e-portfolio process and defines types of engagement experienced by the user. The factors which impact on the type of engagement enjoyed by the user are numerous and the paper will argue that feedback provision and relevance are the two most importan...

Global change has been predominantly studied from the prism of ‘how much' rather than fast' occurs. Associated to this, there a focus on environmental drivers crossing critical value and causing so‐called regime shifts. This presupposes that rate at which conditions is slow enough allow ecological entity remain close stable attractor (e.g. an equilibrium). However, occurring unprecedented rates...

Background & Aims of the Study: Fatigue is one of the most important issues relating with safety and other aspects of human life. To understand fatigue and its relative factors and causes, there is a need to useful instruments, such as self-reported scales. The purpose of this study is to identify and present useful self-reported scales to measure fatigue. Materials & Methods: Data were extrac...

Maintaining good soil productivity in rice paddies is important for global food security. Numerous methods have been developed to evaluate paddy soil productivity (PSP), most based on soil physiochemical properties and relatively few on biological indices. Here, we used a long-term dataset from experiments on paddy fields at eight county sites and a short-term dataset from a single field experi...
