Prevalence of Autism Spectrum Disorders in Ecuador: A pilot study in Quito

This research presents the results of the first phase of the study on the prevalence of pupils with Autism Spectrum Disorder (ASD) in regular education in Quito, Ecuador. One-hundred-and-sixty-one regular schools in Quito were selected with a total of 51,453 pupils. Prevalence of ASD was assessed by an interview with the rector of the school or its delegate. Results show an extremely low prevalence of 0.11 % of pupils with any ASD diagnosis; another 0.21 % were suspected to have ASD, but were without a diagnosis. This low prevalence suggests that children and adolescents with ASD are not included in regular education in Quito. These results are discussed in the light of low diagnostic identification of ASD and low inclusion tolerance

Integration of Biological, Psychological and Social Aspects in Agent-Based Simulation of a Violent Psychopath

Abstract. In the analysis of criminal behaviour, a combination of biological, psychological and social aspects may be taken into account. Dynamical modelling methods developed in recent years often address these aspects separately. This paper contributes an agent-based modelling approach for behaviour of a certain criminal type, the violent psychopath, in which these aspects are integrated in one dynamical system. It is shown how within a certain social context, an interaction between biological factors and cognitive and emotional factors can lead to a crime committed when an opportunity is perceived

Towards Integration of Biological, Psychological, and Social Aspects in Agent-Based Simulation of Violent Offenders

In the analysis of criminal behavior, a combination of biological, psychological and social aspects may be taken into account. Dynamical modeling methods developed in recent years often address biological, psychological or social dynamical systems separately. This paper makes the first step in the development of an agent-based modeling approach for criminal behavior in which these aspects are integrated in one dynamical system. It is shown how within a certain (multi-agent) social context, biological factors, such as certain brain deviations, testosterone levels and serotonin levels, affect cognitive and emotional functioning in such a way that a crime is committed when the perceived opportunity is there. This paper presents one generic model for the behavior of violent offenders with parameters that can be set to obtain simulation traces for three known types of offenders. © 2009, SAGE Publications.
