At the core of adaptive learning systems is an adaptation engine which decides the adaptations based on the learner’s profile, educational activity, infrastructure and/or environment. This paper presents a model for adaptation engines. Then it presents 17 criteria for the evaluation of an adaptation engine.

UNLABELLED Mentoring is a complex developmental relationship that contributes to individual growth and career advancement in different areas of human activity, including academic medicine. This article describes a broader environmental milieux in which mentoring occurs and considers the ways in which the environmental factors may affect the process and outcomes of mentoring. An ecological model...

Experimental evidence of extinction via an Allee effect (AE) is a priority as more species become threatened by human activity. Kramer & Drake (2010) begin the International Year of Biodiversity with the important--but double-edged--demonstration that predators can induce an AE in their prey. The good news is that their experiments help bridge the knowledge gap between theoretical and empirical...

Humans commonly engage in tasks that require or are made more efficient by coordinating with other humans. In this paper we introduce a task dynamics approach for modeling multi-agent interaction and decision making in a pick and place task where an agent must move an object from one location to another and decide whether to act alone or with a partner. Our aims were to identify and model (1) t...

BACKGROUND AND AIMS Information on the effect of students' class attendance on examination performance in a problem-based learning medical curriculum is limited. This study investigates the impact of different educational activities on students' academic performance in a problem-based learning curriculum. METHODS This is a retrospective cohort study conducted on the cardiology block at the Co...

While acknowledging the need for “sustainability,” this paper summarizes the problems that have been encountered in our understanding and use of this concept. It explores the efforts of others to define the concept within the context of specific disciplinary areas and sets forth a proposal for a basic understanding of the term “environmental sustainability” as an expansion of our common percept...

Chiropractic is a popular health care choice in Australia and yet major gaps in our empirical understanding of this area of practice remain. Furthermore, while some research excellence exists, a largely uncoordinated approach to research activity and development has in effect led to silos of interest and a lack of strategic 'big-picture' planning essential to producing a sustainable research cu...

E-learners are generally adults with work and family constraints who get involved in the virtual campus looking for temporary academic flexibility. However, they are often confronted with collaborative learning activities which lead to additional organizational efforts by reducing their individual time flexibility. In this paper, we argue that time is a major variable in Computer Supported Coll...

Principles of self-organization play an increasingly central role in models of human activity. Notably, individual human displacements exhibit strongly recurrent patterns that are characterized by scaling laws and can be mechanistically modelled as self-attracting walks. Recurrence is not, however, unique to human displacements. Here we report that the mobility patterns of wild capuchin monkeys...

Transitions from marine to freshwater habitats constitute dramatic shifts between 'adaptive zones' that have initiated the radiation and speciation of many taxa. As recently as 10?000 years ago, deglaciation resulted in marine fauna being trapped in freshwater lakes. In modern times, human activity has caused the acceleration of freshwater invasions from marine or brackish habitats, leading to ...
