This paper presents a case study where twelve graduate students undertook the demanding role of the adaptive e-course developer and worked collaboratively on an authentic and complex design task in the context of open and distance tertiary education. The students had to work in groups in order to conceptualise and design a learning scenario for adaptive learning, develop learning materials and ...

There are two dominant approaches to describe and understand the anatomy of complete health and well-being systems internationally. Yet, neither approach has been able to either predict or explain occasional but dramatic crises in health and well-being systems around the world and in developed emerging market or developing country contexts. As the impacts of such events can be measured not simp...

If we consider the worldwide maritime shipping industry as a system, we observe that a large number of independent rational agents such as port authorities, shipping service providers, shipping companies, and commodity producers play a role in achieving predominant positions and in increasing market share. The maritime shipping industry can, from this perspective, be defined as a Complex System...

The web continues to grow at a phenomenal rate and the amount of information on the web is overwhelming. Finding the relevant information on the web remains a big challenge. Due to its wide distribution, its openness and high dynamics, the WWW is a complex system, for which we have to imagine mechanisms of content maintaining, filtering and organizing that are able to deal with its evolving dyn...

Nowadays the interest to the adaptive intelligent eLearning systems increases. There are different kind of adaptations one to the content, other to the learning process or to the assessment and so on. The crucial moment for the learner motivation’s is to catch their needs and possibilities and then to act, i.e. the respond from the system.. The intelligent tutor (system agent(s)) has to decide ...

1 Introduction

Representing the image as a surface, an inhomogeneous diffusion algorithm is developed, evolving the surface at a speed proportional to its mean curvature, reducing noise while preserving image structure. An adaptive scaling parameter increases the speed of the diffusion. The properties of a discrete algorithm are demonstrated experimentally.

Web-based learning systems, if designed appropriately, offer many advantages over the traditional learning environments. This study addresses the design and development of new approaches and network technologies based on the newly induced pedagogical models to support collaborative teaching, knowledge sharing, lifelong learning opportunities for anyone to offer or participate in courses free of...

In clinical trials with extreme outcomes, it is ethically desirable to treat as many trial patients as possible with the superior treatment. Adaptive designs seek to achieve this goal. One such design is known as the randomized play the winner rule which has been applied in some real clinical trials. In this paper we demonstrate some interesting and desirable properties of the randomized play t...
