A Web-based Application to Address Individual Interests of Children with Autism Spectrum Disorders

AbstractAutism spectrum disorders (ASDs) are a triad of disturbances affecting the areas of communication, social inter- action and behavior. In educational contexts, these limitations can be deeply disabling unless appropriate intervention methodologies are promoted. Children with ASDs usually have very strict interests, which may cause a lack of interest in standard ICT tools overtime. Our paper presents a new way to overcome these issues, by enabling children to have the opportunity to enjoy a rich multimedia platform. This approach allows tutors and peers to prepare a unique setup for the child's needs, giving the possibility to fully customize the layout and contents. Special attention was given to the promotion of communicative and social competences of children with ASDs, enabling them to interact with one another through messages, share opinions, and experiences. Preliminary results show that children feel motivated using the tool, and number of interactions between peers increase. In this paper we will describe the platform and how it can be customized, and finally, introduce the evaluation methodology to be used

A Tissue P System and a DNA Microfluidic Device for Solving the Shortest Common Superstring Problem

This paper describes a tissue P system for solving the Shortest Common Superstring Problem in linear time. This tissue P system is well suited for parallel and distributed implementation using a micro°uidic device working with DNA strands. The tP system is not based on the usual brute force generate/test technique applied in DNA computing, but builds the space solution gradually. The possible solutions/superstrings are build step by step through the parallel distributed combination of strings using the overlapping concatenation operation. Moreover, the DNA micro°uidic device solves the problem autonomously, without the need of external control or manipulation

Grau de aderência aos requisitos de divulgação dos instrumentos financeiros derivativos : um estudo das empresas exportadoras de capital aberto do Brasil

Os derivativos são produtos que minimizam os riscos das companhias que os utilizam. Atualmente, são usados extensivamente pelas grandes corporações mundiais para fins de proteção, principalmente em relação ao câmbio, porém o seu uso pode causar danos relevantes para o resultado financeiro dessas organizações. As empresas de capital aberto devem evidenciar informações referente ao uso desses instrumentos. Como as empresas exportadoras necessitam se proteger do risco de câmbio, muitas delas utilizam os derivativos para esse fim. Portanto, este trabalho tem por objetivo verificar o nível de aderência das maiores empresas abertas exportadoras brasileiras em relação as normas de disclosure referente aos instrumento financeiros derivativos. Foi realizada uma pesquisa descritiva, documental, intencional em relação a amostra e com uma observação sistemática para o tratamento dos dados. Assim, foi efetuada uma análise de 27 companhias abertas brasileiras em relação ao CPC 40 – Instrumentos Financeiros: Instrumentos Financeiros: Evidenciação, o qual dispõesobre as informações que devem ser divulgadas referente ao uso dos instrumentos financeiros entre as empresas brasileiras, com os dados financeiros dessas organizações dos anos de 2016 e 2017. A partir da análise dos dados, pode-se concluir que a maioria dos itens requeridos foram atendidos pelas empresas, com uma média de aderência de 60,2% em 2016 e 63,7% em 2017, porém, nenhuma das companhias pesquisadas seguem plenamente as normas contábeis vigentes de disclosure referente aos derivativos, com as informações sobre o impairment sendo o item menos divulgado entre as empresas

Unpacking the relationship between screen use and educational outcomes in childhood: a systematic literature review

[EN] The increasing digitization of society has led to the growing immersion of children in virtual culture, raising concerns about how screen use affects their educational and personal development. Through a Systematic Literature Review (SLR) and Textual Data Mining (TDM), this study explores the profile of digital technology use, behaviour, and effects on childhood. We identify three distinct periods in the study of these effects: pre-2016, focused on addiction and health; 2016–2020, focused on educational applications and the role of families; and post-2020, with an emphasis on negative repercussions for identity construction, health, well-being, and behaviour. Our findings reveal a growing concern about the cognitive and emotional impact of screen use, underscoring the importance of teacher training and digital literacy for children and parents for appropriate and healthy use of technology. In contrast to what has been previously known, this study highlights the dynamic change in issues of concern about childhood screen use over time and emphasizes the need for educational strategies adapted to emerging digital cultural realities. This comprehensive approach offers a deeper insight into the dual role of technology as both an educational tool and a source of risk, providing a foundation for the development of informed and responsible educational practices in the digital age.https://doi.org/10.1016/j.compedu.2024.105049https://doi.org/10.1016/j.compedu.2024.10504

Investigation of main and secondary transformers on mitigation of voltage sags, swells and interruptions in unbalanced medium voltage distribution systems

Since voltage interruptions, sags and swells are Power Quality (PQ) disturbances with great economic impact, studies that seek alternatives to mitigate its effects have been conducted extensively. The PQ Brazilian standard names these disturbances as Short-Duration Voltage Variations (SDVVs), classified them in terms of magnitude, duration, and frequency of occurrence. These parameters are used to calculate the Impact Factor (IF) of SDVVs, a severity-characterization index of their incidence. In this context, this work assesses the influence of three-phase transformer winding connection and neutral grounding on the quantities of SDVVs and the IF observed by an industrial consumer in a distribution system. Fault simulations at ATPEMTP perform the study, considering two different winding connections for the secondary transformer and applying a grounding resistance to the neutral of the main transformer of the distribution system. The SDVVs are verified in two different ways: phase-to-ground and phase-to-phase voltages. It is observed that there are differences in these quantities and for the value of the IF due to the winding connection of the secondary transformer, the value of the neutral grounding resistance of the main transformer and the ways of voltage verification

O clubismo no jornalismo esportivo: análise do programa Jogo Aberto

The present work seeks to analyze and analyze how the so - called clubism is linked to the current structure of sports journalism. It is clear that in this area impartiality is recurrent, but in this context the rule does not apply. The corpus selected was the "Jogo Aberto" soccer program, which was televised weekly by Bandeirantes TV, with a total of five exhibitions in a period after the World Cup between July and August 2018. Thus, the intention is to understand through the analysis of the French line discourse, using the ethos figure, as the speech enunciated by Renata Fan and Denílson portray this question, directly interfering in the content produced in the round table.Trabalho de Conclusão de Curso (Graduação)O presente trabalho procura discorrer e analisar de que forma o chamado clubismo está ligado a atual estrutura do jornalismo esportivo. É nítida a concepção de que nesta área a imparcialidade é algo recorrente, porém neste contexto a regra pouca se aplica. O corpus selecionado fora o programa futebolístico ‘‘Jogo Aberto’’, exibido semanalmente pela TV Bandeirantes, com um total de cinco exibições, ocorridas em um período pós Copa do Mundo, compreendido entre os meses de Julho e Agosto de 2018. Sendo assim, o intuito é compreender através da análise do discurso de linha francesa, utilizando a figura do ethos, como a fala enunciada por Renata Fan e Denílson retratam esta questão, interferindo diretamente na contéudo produzido na mesa redonda
