    A study in cross-cultural transmission of natural philosophy: the Kenkon Bensetsu

    Get PDF
    Dissertação apresentada para cumprimento dos requisitos necessários à obtenção do grau de Doutor em História dos Descobrimentos e da Expansão PortuguesaThis work shows that the transmission of European natural philosophy by Christian missionaries in Japan during the sixteenth and seventeenth centuries was made in a systematic way, even if at an elementary level. The Kenkon Bensetsu is used as main evidence of this. This text was introduced into Japan by Antonio Rubino, on the orders of Inoue Masashige it was translated by Sawano Chuan, at the request of Kainosho Masanobu it was transliterated by Nishi Kichibei and Mukai Gensho, and this last one also wrote a commentary on its theories from a neo-Confucian perspective. The historical setting and the process that led to the production of the Kenkon Bensetsu are described. From this it is established that the Japanese of all walks of life were curious about the causes of natural phenomena; that the missionaries had the ability to provide those explanations, drawing from the pool of theories provided by sixteenth century Aristotelian natural philosophy, adjusted to the interests and talents of their audience; and that the Japanese authorities considered that these theories were important in some way and thus took the necessary steps to ensure that that they would not be consigned into oblivion as a consequence of their efforts to stamp out Christianity. The text is integrally translated following explicit criteria, therefore opening the way to further exploration by many researchers. Some of its most striking characteristics concerning content and style are analysed

    This study aimed to identify the indicators of reception (receptivity model) to the Physical Education intern by his/her Supervising Teacher (PS) during the supervised internship period. The method used was qualitative, case study type, from the perspective of the Descriptive Analytical Model. The participants were a supervising physical education teacher and her intern. The instruments used were semi-structured interviews, on-site observations, and final internship report, all analyzed through the Content Analysis Technique. The results indicated that the Supervising Teacher provided an internship with predominant elements of the Formative Welcoming, prioritizing the partnership and the integration of the intern to the school environment.Este estudio tuvo como objetivo identificar los indicadores de acogida (modelo de receptividad) del becario de Educación Física por su Docente Supervisor (PS) durante el período de prácticas supervisadas. El método utilizado fue el cualitativo, tipo estudio de caso, desde la perspectiva del Modelo Analítico Descriptivo. Los participantes fueron una maestra supervisora de Educación Física de la red de educación básica y su becaria. Los instrumentos para la recolección fueron Entrevistas Semiestructuradas, Observaciones in loco, Informe Final de Pasantía, y todos fueron analizados mediante la Técnica de Análisis de Contenido. Los resultados mostraron que el Docente Supervisor brindó una pasantía con elementos predominantes de la Recepción Formativa, priorizando la asociación y la integración del pasante en el ámbito escolar.Esse estudo teve como objetivo identificar os indicadores de acolhimento (modelo de receptividade) ao estagiário de Educação Física, pela sua Professora Supervisora (PS), durante o período de estágio supervisionado.

    O presente artigo descreve o ciclo de desenho de um protótipo Role-playing game desenvolvido em Scratch para alunos do 12.o ano a frequentarem a disciplina opcional de Aplicações Informáticas B. É dado especial destaque ao processo de avaliação da usabilidade, nomeadamente a avaliação com especialistas e com utilizadores semelhantes aos finais recorrendo a vários métodos e técnicas de recolha de dados. O processo foi iniciado com uma investigação preliminar realizando um teste exploratório com o público-alvo. De seguida, foi criada a primeira versão do jogo que foi alvo da avaliação heurística. Esta avaliação foi realizada com recurso às heurísticas de Nielsen para a usabilidade e as heurísticas de Malone para o divertimento. A partir das recomendações dos peritos, foi criada uma nova versão, submetida à avaliação por parte de utilizadores semelhantes aos finais. O grau médio de satisfação obtido através do questionário SUS foi de 76 numa escala de 0 a 100 pontos, no entanto, foram identificados alguns erros de usabilidade e divertimento que serão corrigidos e alvo de novos testes.This article describes the designing cycle of a Role - playing prototype game using Scratch software. T his prototype was developed for 12th grade students attending the optional subject of Computer Applications B. Special emphasis is given to the process of usability evaluation, including evaluation with experts and representative end users using several me thods and techniques of data collection. The process began with a preliminary investigation conducting an exploratory testing with the target audience. Then, the first version of the game was created and was the target of heuristic evaluation. This evaluat ion was performed using Nielsen's usability heuristics and Malone’s heuristics for entertainment. Based on the recommendations of the experts, we created a new version for evaluation by users similar to the final ones. The average degree of satisfaction ob tained through the SUS questionnaire was 76 on a scale of 0 to 100 points. However, some usability and entertainment errors were identified, whichwill be corrected and the target for new tests.CIEC - Centro de Investigação em Estudos da Criança, UM (UI 317 da FCT

    Commitment to Work and its Relationship with Organizational Culture Mediated by Satisfaction

    Get PDF
    Purpose – The objective of this study is to analyze the mediating effect of satisfaction on the relationship between organizational culture and commitment at work. Design/methodology/approach – This paper adopts a quantitative and descriptive approach, applying an online questionnaire to employees of a public development bank operating in the Northeast of Brazil. The analysis method involved the use of structural equations modeling. Findings – The main results indicate that job satisfaction plays an important role in employee commitment, mediating the positive influence of organizational culture on commitment to work in its affective, instrumental, and normative dimensions in adhocratic cultures, and on affective commitment in clan cultures. They also indicate that satisfaction is a direct predictor of organizational commitment in the same way it mediates the relationship between culture and commitment. Originality/value – This paper contributes to increasing the theoretical knowledge about the relationships established between culture, satisfaction, and commitment. For the area of people management, this knowledge can favor organizational performance, allowing managers to act more accurately in each of these constructs

    Measurement of isolated-photon pair production in pppp collisions at s=7\sqrt{s}=7 TeV with the ATLAS detector

    The ATLAS experiment at the LHC has measured the production cross section of events with two isolated photons in the final state, in proton-proton collisions at . The full data set collected in 2011, corresponding to an integrated luminosity of 4.9 fb(−1), is used. The amount of background, from hadronic jets and isolated electrons, is estimated with data-driven techniques and subtracted. The total cross section, for two isolated photons with transverse energies above 25 GeV and 22 GeV respectively, in the acceptance of the electromagnetic calorimeter (|η| &lt; 1.37 and 1.52 &lt; |η| &lt; 2.37) and with an angular separation ΔR &gt; 0.4, is pb. The differential cross sections as a function of the di-photon invariant mass, transverse momentum, azimuthal separation, and cosine of the polar angle of the largest transverse energy photon in the Collins-Soper di-photon rest frame are also measured. The results are compared to the prediction of leading-order parton-shower and next-to-leading-order and next-to-next-to-leading-order parton-level generators.Peer Reviewe
