Psychological assessment in high ability and excellence

Este artigo objetiva discutir as condições de avaliação psicológica das altas habilidades e da excelência. Esses construtos reportam-se a realidades psicológicas distintas nas dimensões em que são definidos, mas a sua avaliação deve sempre ser pautada por parâmetros de precisão e validade. Se nas altas habilidades predominam as variáveis internas, e isso leva ao uso dos testes psicológicos, na excelência convergem os fatores contextuais de aprendizagem, treino e realização, apelando às entrevistas, histórias de vida e observação dos desempenhos na execução da avaliação. Um objetivo central da avaliação psicológica das altas habilidades e excelência, tendo em vista a identificação de tais indivíduos, é evitar os falsos positivos e os falsos negativos nos diagnósticos, tanto pelo impacto negativo que a avaliação pode ter na vida desses indivíduos, quanto para a adequada e necessária orientação. Além disso, dos processos de avaliação e consequente recolha de informações, podem decorrer programas de estimulação orientados que apoiem as necessidades específicas desses indivíduos talentosos.This paper aims to discuss the conditions for psychological assessment of high ability and excellence. These constructs relate to the different realities in terms of psychological dimensions that define them, but their evaluation should be guided by criteria of reliability and validity. If the high ability dominates the internal variables and those appeals to psychological tests, contextual factors converge on the excellence of learning, training and performance, appealing to the interviews, life histories and observation of performance. A main purpose of psychological assessment of high ability and excellence, trying to identify such individuals is to avoid false positives and false negatives in such diagnoses, considering the negative impact that such an assessment can have on the lives of these individuals, as well as an appropriate and necessary guidance. In addition, procedures for assessment and subsequent collection of information, can generate more focused and oriented stimulation programs that support the specific needs of talented individuals

An early start in robotics: K-12 case-study

This paper describes a study carried out with K-12 students. This study is focused on understanding the motivation of these students on the use of robots in the Project Area curricular unit and to understand whether they want to continue their studies in technology areas. K-12 students participated in the RoboParty® event, where the main task is to assemble and program a robot. In other words, the students, in a simple and entertaining way and guided by qualified tutors, learned how to build a robot. At the end of the academic year, a questionnaire was applied to identify and evaluate the K-12 students' opinions regarding the experience. The students’ reaction to this experience as well to the direct contact with the university environment was quite positive.Fundação para a Ciência e a Tecnologia (FCT

The morita-baylis-hillman reaction: advances and contributions from brazilian chemistry

The Morita-Baylis-Hillman reaction is an organocatalyzed chemical transformation that allows access to small poly-functionalized molecules and has considerable synthetic potential and promising biological profiles. In this review, we report the efforts made by Brazilian research groups in recent years on the development of Morita-Baylis-Hillman chemistry. The review covers these contributions, with a focus on mechanistic studies, improvement of the experimental conditions, and the use of Morita-Baylis-Hillman adducts as building blocks for the synthesis of heterocycles, natural products and drugs126830852CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPsem informação2013/10449-5; 2013/07600-5; 2012/08048-

Non-Destructive Inspection of High Temperature Piping Combining Ultrasound and Eddy Current Testing

Project Hi2TRUST—Second generation platform for high-temperature component inspection, (Ref. 3335), supported by Fundo Europeu de Desenvolvimento Regional (FEDER), Programa Operacional Regional de Lisboa (Lisb@2020 and Portugal2020). Publisher Copyright: © 2023 by the authors.This paper presents an automated Non-Destructive Testing (NDT) system for the in-service inspection of orbital welds on tubular components operating at temperatures as high as 200 °C. The combination of two different NDT methods and respective inspection systems is here proposed to cover the detection of all potential defective weld conditions. The proposed NDT system combines ultrasounds and Eddy current techniques with dedicated approaches for dealing with high temperature conditions. Phased array ultrasound was employed, searching for volumetric defects within the weld bead volume while Eddy currents were used to look for surface and sub-surface cracks. The results from the phased array ultrasound results showed the effectiveness of the cooling mechanisms and that temperature effects on sound attenuation can be easily compensated for up to 200 °C. The Eddy current results showed almost no influence when temperatures were raised up to 300 °C.publishersversionpublishe

Materials from renewable resources: new properties and functions

Sustainable production requires increasing use of raw materials from renewable sources, processed under mild conditions with minimal effluent production. These requirements are satisfied by using materials derived from biomass, in synergy with food and energy production. The possibilities of biomass are continuously enlarged by new findings, as in the intrinsic nanocomposite properties of natural rubber and the amphiphile behavior of cellulose that translated into new functional materials, including high-performance, flexible and conductive non-metallic materials. Other findings are allowing a better understanding of electrostatic phenomena that play a positive role in electrostatic adhesion and cohesion of nanocomposites made from biomass products. Moreover, this should allow the development of safe electrostatic separation techniques, suitable for the fractionation of crude mixtures of biomass residues. A current study on rubber electrostatics is showing its capabilities as a transducer of mechanical energy while providing clues to understand the performance of the dielectric elastomers used in robotic self-sensing actuators914CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESP465452/2014-088887.284776/2018-002014/50906-

Balanço de nutrientes no braço sul do estuário do rio Mondego

Na sequência de estudos realizados no domínio da análise de vulnerabilidade da costa litoral portuguesa, entendeu-se pertinente desenvolver um programa de investigação sobre o braço sul do estuário do rio Mondego visando, fundamentalmente, os seguintes aspectos: caracterização das marés, caudais fluviais e descargas de fontes poluidoras; modelação hidrodinâmica do sistema; avaliação do balanço anual de nutrientes; análise da vulnerabilidade deste sistema à eutrofização. Neste trabalho procedeu-se à modelação do sistema utilizando um modelo de qualidade unidimensional (DUFLOW) e os dados existentes. A não adopção, nesta fase, dum modelo multidimensional deve-se não só à não simultaneidade das medições dos parâmetros nos vários pontos de amostragem, mas, sobretudo, ao objectivo do presente trabalho: estimar o balanço de nutrientes neste sistema estuarino

Leadership model

The Theory of Planned Behavior studies the decision-making mechanisms of individuals. We propose the Nash Equilibria as one, of many, possible mechanisms of transforming human intentions in behavior. This process corresponds to the best strategic individual decision taking in account the collective response. We built a game theoretical model to understand the role of leaders in decision-making of individuals or groups. We study the characteristics of the leaders that can have a positive or negative influence over others behavioral decisions.Previous versions of this work were presented in the International Congress of Mathematicians ICM 2010, the Second Brazilian Workshop of the Game Theory Society in honor of John Nash and EURO 2010, ICDEA 2009 and LAMES 2008.

Fricción y tensión tangencial por fondo con ola y corriente

[ES] Se calcula la tensión tangencial debido a ola y corriente mediante un modelo numérico con cierre turbulento K-L, donde K es la energía cinética turbulenta y L es la escala longitudinal de turbulencia. Se obtiene el coeficiente de fricción parametrizado para el caso de flujo turbulento rugoso, siguiendo a Soulsby et al. (1994) y se amplía al caso de flujo turbulento liso. La comparación de estos resultados con otros existentes en la literatura, especialmente los proporcionados por Tanaka y Thu (1994) muestra un buen ajuste.Se propone una nueva parametrización de la serie temporal de la tensión tangencial que incluye el coeficiente de fricción local obteniéndose mejores resultados que aplicando la parametrización propuesta por Soulsby et al.
