Content validity and preliminary structural validity of the sensory integration infant routines questionnaire

This study examined the content validity and preliminary structural validity of the Sensory Integration Infant Routines Questionnaire (SIIRQ), a tool designed to screen for behaviors reflecting possible sensory integration concerns in children aged between 8 and 24 months. This study included two main phases. In phase 1, we examined content validity through cognitive interviews with experts and caregivers. In phase 2, we explored preliminary structural validity through item discrimination, analyzing the dispersion of responses within the 4-point Likert scale. Preliminary internal consistency using Cronbach's alpha was also explored. Experts demonstrated a high degree of agreement, and their input was useful in establishing items to help identify sensory integration vulnerabilities within daily routines. Caregivers unanimously reported that the instrument and the instructions were easy-to-understand. The questionnaire item responses demonstrated good dispersion and appear to capture behaviors that are consistent with sensory integration concerns in daily routines. The homogeneity of the items within each dimension (Cronbach's alpha) ranged from 0.60 to 0.87. The final version of the questionnaire includes 102 items aimed at detecting sensory integration vulnerabilities within the child's daily routines, in accordance with currently accepted models of early intervention.This work was financially supported by Portuguese national funds through the FCT (Foundation for Science and Technology) within the framework of the CIEC (Research Center for Child Studies of the University of Minho) projects under the references UIDB/00317/2020 and UIDP/00317/2020.

Dark Matter and Fundamental Physics with the Cherenkov Telescope Array

The Cherenkov Telescope Array (CTA) is a project for a next-generation observatory for very high energy (GeV-TeV) ground-based gamma-ray astronomy, currently in its design phase, and foreseen to be operative a few years from now. Several tens of telescopes of 2-3 different sizes, distributed over a large area, will allow for a sensitivity about a factor 10 better than current instruments such as H.E.S.S, MAGIC and VERITAS, an energy coverage from a few tens of GeV to several tens of TeV, and a field of view of up to 10 deg. In the following study, we investigate the prospects for CTA to study several science questions that influence our current knowledge of fundamental physics. Based on conservative assumptions for the performance of the different CTA telescope configurations, we employ a Monte Carlo based approach to evaluate the prospects for detection. First, we discuss CTA prospects for cold dark matter searches, following different observational strategies: in dwarf satellite galaxies of the Milky Way, in the region close to the Galactic Centre, and in clusters of galaxies. The possible search for spatial signatures, facilitated by the larger field of view of CTA, is also discussed. Next we consider searches for axion-like particles which, besides being possible candidates for dark matter may also explain the unexpectedly low absorption by extragalactic background light of gamma rays from very distant blazars. Simulated light-curves of flaring sources are also used to determine the sensitivity to violations of Lorentz Invariance by detection of the possible delay between the arrival times of photons at different energies. Finally, we mention searches for other exotic physics with CTA.Comment: (31 pages, Accepted for publication in Astroparticle Physics

Strategic Research & Innovation Agenda for Organics and agroecology

TP Organics is one of the 40 European Technology Platforms recognized by the European Commission. Since 2007, TP Organics has been shaping research and innovation agendas to advocate for more sustainable food and farming systems in Europe based on organic and agroecological principles. The research priorities outlined in this publication are the result of intensive discussions, workshops and consultations that TP Organics held in 2018–2019. The priorities are the reflection of the knowledge and innovation needs of farmers, processors, companies, and civil society groups. They are eager to work with researchers and transform the food and farming systems of Europe. Our food and farming systems need to be climate-neutral, circular, diverse and fair. They need to be prepared for the rapid digitalisation of our economies, which brings new opportunities but also comes with risks. To achieve this, all actors need to change the way we produce and consume our food. Policy makers have a crucial role to play in this transformation. Their role is to ensure a common, integrated and holistic approach to food policy. An approach that has a long-term vision for the future, harmonizes goals, strategies and actions across sectors1, prioritizes investment for public goods and engages diverse actors in making this happen. TP Organics is convinced that research and innovation on organics and agroecology can enable the transition of our food systems towards a more sustainable future for all. The Strategic Research and Innovation Agenda shows concrete research areas and priorities that need to receive proper support at EU level, in particular through Horizon Europe, the European Partnerships and Missions as well as EIP-AGRI, in order to leverage the potential of organics and agroecology
