A importância da viagem precursora na criação de novas atividades do Projeto Rondon: bailando em direção ao futuro

Trabalho apresentado no II Congresso Nacional do PROJETO RONDON, realizado em Florianópolis, SC, no período de 23 a 25 de setembro de 2015 - Universidade Federal de Santa Catarina.O Projeto Rondon, iniciativa coordenada pelo Ministério da Defesa, visa, sobretudo promover a integração de universitários de todo país a regiões carentes. Essa integração se dá por meio de ações adequadas para o local específico onde serão implementadas. Para tanto, é necessário que na fase que antecede a ida dos estudantes a campo, seja realizada a viagem precursora, esta, é feita por um dos professores que estará coordenando a equipe de alunos na execução das propostas, para o município que irá receber as ações do Projeto. Entre os diversos objetivos desta viagem, este trabalho destaca sua importância na criação de uma nova atividade de acordo com a demanda percebida no local. Este estudo de caso descritivo, buscará descrever como a viagem precursora de um professor para o município de Salgado de São Félix/PB resultou em uma oficina de ballet clássico. Demosntrando ainda o quão importante é que os coordenadores da equipe formada para atuar na cidade conheçam o perfil de seus membros, para além de seus currículos acadêmicos e profissionais

Early communication indicator: an analysis with three Portuguese toddlers

Professionals need efficient tools in early childhood communication development to identify infants and toddlers who are at risk of communication disorders or language delays. In Portugal, this project was carried out to respond to these needs due to a lack of these resources and a high prevalence of children at risk for communication problems at early ages. This paper describes the first steps to adapt the Early Communication Indicator (ECI) for the Portuguese population. The ECI is a play-based expressive communication measure for infants and toddlers aged 6 to 42 months. The ECI was originally developed in the U.S. and was designed for use by service providers to provide information about growth in communication, to help in intervention decision making, and to be administered in any language. This paper analyzes the ECI results of three Portuguese children in relation to their communication progression, based on a one-year longitudinal study. The ECI was administered when children were 17, 24, and 30 months of age. The ECI results showed that two of the children follow the typical progression of communication acquisition, with acquisition of earlier prelinguistic skills preceding growth in spoken language. The ECI results for the other child showed a very different and slower progression in the communication skills. The data obtained provided just an initial demonstration of the use of the ECI with Portuguese children. More research is needed into the development of the ECI in the Portuguese context, such as the development of a nationally representative, normative sample. Therefore, a discussion of what is needed in research and practice to advance this project is provided.Los profesionales necesitan herramientas eficaces en el desarrollo de la comunicación en la primera infancia para identificar a los bebés y niños pequeños que corren el riesgo de sufrir trastornos de la comunicación o retrasos en el lenguaje. En Portugal, este estudio se llevó a cabo para responder a estas necesidades debido a la falta de estos recursos y a una alta prevalencia de niños con riesgo de problemas de comunicación a edades tempranas. Este trabajo describe los primeros pasos para adaptar el Indicador de Comunicación Temprana (ECI) a la población portuguesa. El ECI es una medida de comunicación expresiva basada en el juego para bebés y niños pequeños de 6 a 42 meses. El ECI fue desarrollado originalmente en los EE.UU. y fue diseñado para ser utilizado por los proveedores de servicios para proporcionar información sobre el crecimiento en la comunicación, para ayudar en la toma de decisiones de intervención, y para ser administrado en cualquier idioma. Este trabajo analiza los resultados del ECI de tres niños portugueses en relación con su progresión comunicativa, basándose en un estudio longitudinal de un año. La ECI se administró cuando los niños tenían 17, 24 y 30 meses de edad. Los resultados del ECI mostraron que dos de los niños seguían la progresión típica de la adquisición de la comunicación, con la adquisición de habilidades prelingüísticas anteriores al crecimiento del lenguaje hablado. Los resultados de la ECI del otro niño mostraron una progresión muy diferente y más lenta en las habilidades comunicativas. Los datos obtenidos proporcionaron sólo una demostración inicial del uso de la ECI con niños portugueses. Se necesita más investigación sobre el desarrollo de la ECI en el contexto portugués, como el desarrollo de una muestra normativa representativa a nivel nacional. Por lo tanto, se presenta una discusión sobre lo que se necesita en la investigación y en la práctica para avanzar en la línea que marca este estudio.This work was supported by the Portuguese Funding Agency for Science and Technology (FCT) under the reference SFRH/ BD/138965/2018, within the framework of CIEC (Research Centre on Child Studies, Institute of Education, University of Minho), projects under the references UIDB/00317/2020 and UIDP/00317/2020, and CIEd (Research Centre on Education, Institute of Education, University of Minho), projects under the references UIDB/01661/2020 and UIDP/01661/2020, through national funds of FCT/MCTES-PT

Influence of the external pressure on the quantum correlations of molecular magnets

The study of quantum correlations in solid state systems is a large avenue for research and their detection and manipulation are an actual challenge to overcome. In this context, we show by using first-principles calculations on the prototype material KNaCuSi$_{4}$O$_{10}$ that the degree of quantum correlations in this spin cluster system can be managed by external hydrostatic pressure. Our results open the doors for research in detection and manipulation of quantum correlations in magnetic systems with promising applications in quantum information science

Quasinormal modes of a massive scalar field nonminimally coupled to gravity in the spacetime of Self-Dual Black Hole

In this work, we investigate the quasinormal modes for a massive scalar field with a nonminimal coupling with gravity in the spacetime of a loop quantum black hole, known as the Self-Dual Black Hole. In this way, we have calculated the characteristic frequencies using the 3rd order WKB approach, where we can verify a strong dependence with the mass of scalar field, the parameter of nonminimal coupling with gravity, and parameters of the Loop Quantum Gravity. From our results, we can check that the Self-Dual Black Hole is stable under the scalar perturbations when assuming small values for the parameters. Also, such results tell us that the quasinormal modes assume different values for the cases where the mass of field is null and the nonminimal coupling assumes $\xi=0$ and $\xi=1/6$, i.e., a possible breaking of the conformal invariance can be seen in the context of loop quantum black holes.Comment: 15 pages, 2 tables and 8 figures. arXiv admin note: text overlap with arXiv:2005.0220

Studies with screening and assessment instruments in communication and language in Portuguese children with and without language difficulties in inclusive contexts.

[Excerpt) The acquisition of communication and language is fundamental for the child's overall development. Therefore, communication difficulties may negatively influence the child's development, namely at the behavioral, socio-emotional, and cognitive levels (Prelock & Hutchins, 2018). Given the high prevalence of Portuguese children with communication and language difficulties, as well as with difficulties in school learning (Castro et al., 2019), it is essential to identify as early as possible the cases at risk that may require intervention. Thus, this paper aims to present and analyze valid and accurate screening and assessment tools, and to recognize Portuguese children at early ages at risk of language difficulties and disorders

Translaminar Pressure Difference and Ocular Perfusion Pressure in Glaucomatous Eyes with Different Optic Disc Sizes

Purpose: Intracranial pressure (ICP) and ocular perfusion pressure (OPP) are both involved with the pathogenesis of glaucoma. The orbital ICP determines a retrolaminar counter pressure that is antagonistic to the intraocular pressure (IOP). The purpose of this study is to evaluate whether the translaminar pressure difference (TLPD) and the OPP varies in glaucoma patients with different optic disc sizes. Methods: In this university hospital-based, observational, cross-sectional clinical study, all patients underwent an ophthalmic evaluation. Blood pressure, height, weight, and the results of retinal nerve fiber layer examination with optical coherence tomography examination were recorded. TLPD and OPP were calculated for each patient using proxy algorithms to attain indirect surrogate parameter values. Patients’ eyes were stratified into three quantiles according to optic disc sizes and the differences compared. Data from both eyes were used after using the appropriate correction for inter-eye dependency. Results: The sample consisted of 140 eyes of 73 patients with primary open-angle glaucoma and suspects. Patients with large disc size presented with higher TLPD as compared to those with average and small-sized discs (2.4 ± 4.5, 2.8 ± 3.8, and 3.7 ± 4.7 mmHg for first, second, and third tertile, respectively (P < 0.000). OPP did not vary according to the optic disc size. Conclusion: Glaucoma patients with larger optic discs have higher TLPD. The pathological significance of this finding warrants further investigation

Influence of web thickness reduction in the shear resistance of non-prismatic tapered plate girders

The evaluation of deteriorated members with corrosion, and consequent potential degradation of strength, is found in existing plate girder bridges. This difficult engineer’s task is based in a low level of information concerning the shear behaviour of corroded web panels. This insecurity in the evaluation of deterioration members of plate girders bridges must be minimized by using models based on sound theoretical principles, validated by extensive and reliable data. In this paper are presented the results of degradation of strength, for critical and ultimate shear load, on tapered plate girders with local corrosion (web or flanges), using a nonlinear finite element analysis. In this way, it is also presented the development of a data base with several scenarios of degradation for the creation of predictive models for critical and ultimate shear stress in tapered webs, taking into account different scenarios of thickness reduction. In order to analyze the data generated in the finite element model, Data Mining techniques (e.g., Neural Networks) have been used
