BACKGROUND Deficiencies in essential vitamins and minerals-also termed hidden hunger-are pervasive and hold negative consequences for the cognitive and physical development of children. METHODS This analysis evaluates the change in hidden hunger over time in the form of one composite indicator-the Hidden Hunger Index (HHI)-using an unweighted average of prevalence estimates from the Nutrition...

This paper describes a method for learner modelling for use within simulation-based learning environments. The goal of the learner modelling system is to provide the learner with advice on discovery learning. The system analyzes the evidence that a learner has generated for a specific hypothesis, assesses whether the learner needs support on the discovery process, and the nature of that support...

Learner preferences of students have been analysed within two modules that have been given in the department of media using Röll’s learner preference model. A qualitative analysis of the results of an online learner preference test based on this model has been conducted. This analysis showed that for the majority of the students the revealed results were valid. Starting from current methods use...

CM-ED is a Concept Map EDitor developed with the aim of being useful in different contexts and uses of the educational agenda. This paper describes DynMap, a system based on CM-ED for dynamically visualizing the Learner Model of an Intelligent Tutoring System (ITS). The aim is to facilitate teachers to better understand ITS outcomes. The paper, first, describes the structure of the tutors built...

We describe an approach to student modelling where the student can delve into the student model. We describe how this can support learning on several levels. It serves as a basis for planning learning goals, improving communication between the teaching system and the learner, and as an aid to reflection about learning. There is a growing group of researchers working with accessible and understa...

Beim Thema patientenzentrierte Kommunikation hat der Autor vier Aspekte vermisst: Die Kompetenz zur intuitiven Entscheidungsfindung, den Einbezug des Praxis- oder Pflegepersonals, Faktor Zeit sowie die "Hidden Agenda".

This paper explores the potential learning benefits of 3D Learning Environments (3DLEs). It presents definitions of key terms and analyses the learner-computer interactions facilitated by 3DLEs, in order to identifj! the unique characteristics of such environments It is argued that the most important potential contribution of 3DLEs to conceptual understanding is through facilitation of spatial ...

Syndromic surveillance has expanded since 2001 in both scope and geographic reach and has benefited from research studies adapted from numerous disciplines. The practice of syndromic surveillance continues to evolve rapidly. The International Society for Disease Surveillance solicited input from its global surveillance network on key research questions, with the goal of improving syndromic surv...

Hidden Markov Models are a widely used generative model for analysing sequence data. A variant, Profile Hidden Markov Models are a special case used in Bioinformatics to represent, for example, protein families. In this paper we introduce a simple propositionalisation method for Profile Hidden Markov Models. The method allows the use of PHMMs discriminatively in a classification task. Previousl...
