Transition to Product Service Systems: methodology based on scenarios identification, modelling and evaluation
Part 4: Transition Towards Product-Service SystemsInternational audienceThe paper proposes a methodology to support the organisational shift towards product Services Systems. Its backbone is the evaluation of economic impact of such a shift. However, in order to efficiently accommodate organisational changes and include company specificities, other steps are required prior to evaluation. These are context analysis, scenarios identification and modelling. The novelty of the paper lies in (i) including organisational changes in the evaluation and (ii) managing the contextualization to company specificities
Epidemiology of autism spectrum disorder in Portugal: prevalence, clinical characterization, and medical conditions
The objective of this study was to estimate the prevalence of autistic spectrum disorder (ASD) and identify its clinical characterization, and medical conditions in a paediatric population in Portugal. A school survey was conducted in elementary schools, targeting 332,808 school-aged children in the mainland and 10,910 in the Azores islands. Referred children were directly assessed using the Diagnostic and Statistical Manual of Mental Disorders (4th edn), the Autism Diagnostic Interview-Revised, and the Childhood Autism Rating Scale. Clinical history and a laboratory investigation was performed. In parallel, a systematic multi-source search of children known to have autism was carried out in a restricted region. The global prevalence of ASD per 10,000 was 9.2 in mainland, and 15.6 in the Azores, with intriguing regional differences. A diversity of associated medical conditions was documented in 20%, with an unexpectedly high rate of mitochondrial respiratory chain disorders
Stellar Inversion Techniques
Stellar seismic inversions have proved to be a powerful technique for probing
the internal structure of stars, and paving the way for a better understanding
of the underlying physics by revealing some of the shortcomings in current
stellar models. In this lecture, we provide an introduction to this topic by
explaining kernel-based inversion techniques. Specifically, we explain how
various kernels are obtained from the pulsation equations, and describe
inversion techniques such as the Regularised Least-Squares (RLS) and Optimally
Localised Averages (OLA) methods.Comment: 20 pages, 8 figures. Lecture presented at the IVth Azores
