Signs Workshop: the importance of natural gestures in the promotion of early communication skills of children with developmental disabilities

This article emphasises the importance of natural gestures and describes the framework and the development process of the “Signs Workshop” CD-ROM, which is a multimedia application for the promotion of early communication skills of children with developmental disabilities. Signs Workshop CD-ROM was created in the scope of Down’s Comm Project, which was financed by the Calouste Gulbenkian Foundation, and is the result of a partnership between UNICA (Communication and Arts Research Unit of the University of Aveiro) and the Portuguese Down Syndrome Association (APPT21/Differences)

Highly-parallelized simulation of a pixelated LArTPC on a GPU

The rapid development of general-purpose computing on graphics processing units (GPGPU) is allowing the implementation of highly-parallelized Monte Carlo simulation chains for particle physics experiments. This technique is particularly suitable for the simulation of a pixelated charge readout for time projection chambers, given the large number of channels that this technology employs. Here we present the first implementation of a full microphysical simulator of a liquid argon time projection chamber (LArTPC) equipped with light readout and pixelated charge readout, developed for the DUNE Near Detector. The software is implemented with an end-to-end set of GPU-optimized algorithms. The algorithms have been written in Python and translated into CUDA kernels using Numba, a just-in-time compiler for a subset of Python and NumPy instructions. The GPU implementation achieves a speed up of four orders of magnitude compared with the equivalent CPU version. The simulation of the current induced on 10^3 pixels takes around 1 ms on the GPU, compared with approximately 10 s on the CPU. The results of the simulation are compared against data from a pixel-readout LArTPC prototype

Pictorial representations of achievement emotions: Preliminary data with primary school children and adults

Three studies are presented aimed at testing a preliminary version of a pictorial instrument representing children\u2019s achievement emotions as conceptualized in control-value theory. Children (second- and fifth-graders) and adults were administered three tasks assessing the correspondence between drawings of faces and ten achievement emotions (enjoyment, pride, hope, relief, relaxation, anxiety, anger, shame, boredom, and hopelessness): an agreement task (Study 1, n = 46), a matching task (Study 2, n = 47), and a naming task (Study 3, n = 53). Analyses on the agreement and matching task revealed accurate responses for all the emotions, while in the naming task low accuracy emerged for pride, hope, relief, and particularly for boredom. Results are discussed in light of their applicative relevance for the future development of the instrument
