BACKGROUND Little is known about the stability of behavioural and developmental problems as children develop from infants to toddlers in the general population. Therefore, we investigated behavioural profiles at two time points and determined whether behaviours are stable during early development. METHODS Parents of 4,237 children completed questionnaires with 62 items about externalizing, in...

This paper establishes an ontology of creativity and innovation processes. A comprehensive review was undertaken describing the four key perspectives of creativity research, namely the creative-output, -process, -person and -environment. The focus of this review is based around the metrics for measuring creativity from each of the above perspectives. These metrics are drawn together in a common...

This paper proposes a model of expertise of temporary design teams. We start by outlining a situated view of expertise as being grounded in individual experience, which emphasises its applicability and teleology. We use the construct of a computational agent to model the individual expert. We then show the advantages of the function-behaviour-structure (FBS) schema to represent the knowledge of...

The ternary system of Portland cement-microsilica-limestone has been studied by investigating its set and strength behaviours. A number of different cementitious <span style="font-size: 10pt; color: #0...

A novel learning framework is proposed for anomalous behaviour detection in a video surveillance scenario, so that a classifier which distinguishes between normal and anomalous behaviour patterns can be incrementally trained with the assistance of a human operator. We consider the behaviour of pedestrians in terms of motion trajectories, and parametrise these trajectories using the control poin...

This diploma thesis presents an unusual event recognition approach in the field of traffic surveillance. Such events are unusual traffic behaviour like traffic jams, accidents or ghost drivers. An interest-point based tracking algorithm (KLT-tracker) is discussed which pursues features on vehicles through a static camera scene. Tracking data can be collected by observing normal traffic. Then, t...

In this paper a bottom-up approach for human behaviour understanding is presented, using a multi-camera system. The proposed methodology, given a training set of normal data only, classifies behaviour as normal or abnormal, using two different criteria of human behaviour abnormality (short-term behaviour and trajectory of a person). Within this system an one-class support vector machine decides...

The authors describe two cases in which a wrong diagnosis of allergy has negatively affected the normal health behaviour children and their families.
