Initially it presents a brief account of the history of Leonardo Fibonacci, from his most famous work,The Liber Abaci, to the relationship with other elds of Mathematics. Then we will introduce some properties of Fibonacci's Numbers, Binet's Form, Lucas' Numbers and the relationship with Fibonacci's Sequence and an important property observed by Fermat. Within relationships with other areas of Mathematics, we show the relationship Matrices, Trigonometry and Geometry. Also presents the Golden Ellipse and the Golden Hyperbola. We conclude with Tribonacci's Numbers and some properties that govern these numbers. Made some generalizations about Matrices and Polynomials Tribonacci. / Este trabalho tem como objetivo o estudo dos Números de Fibonacci. Apresenta-se inicialmente um breve relato sobre a história de Leonardo Fibonacci, desde sua obra mais famosa, O Liber Abaci, até a relação com outros campos da Matemática. Em seguida, apresenta-se algumas propriedades dos Números de Fibonacci, a Fórmula de Binet, os Números de Lucas e a relação com a Sequência de Fibonacci e uma importante propriedade observada por Fermat. Dentro das relações com outras áreas da Matemática, destacamos a relação com as Matrizes, com a Trigonometria, com a Geometria. Apresenta-se também a Elipse e a Hipérbole de Ouro. Concluímos com os Números Tribonacci e algumas propriedades que regem esses números. Realizamos algumas generalizações sobre Matrizes e Polinômios Tribonacci.

The relation between vocabulary and mental age of a rural white population

Unknown Date (has links)
Study conducted with 63 rural school children, as measured by the Revised Stanford-Binet Intelligence Scale. Since size of vocabulary is considered to be a relatively valid measure of intelligence and correlates to a high degree with the mental age obtained on the Biney scale, it is concluded in accordance with the results of this study, that the test as a whole may be considered a valid measure of the mental ages of rural school children. However, since the cases used in this study were taken from a limited population, the results are not to be considered conclusive, but due to the high correlation obtained, a need for further study is indicated. / "A Paper." / "Submitted to the Graduate Council of Florida State University in partial fulfillment of the requirements for the degree of Master of Science." / "February, 1951." / Typescript. / Advisor: Marcus B.

A compreensão da medida e a medida da compreensão: origens e transformações dos testes psicológicos / Comprehending measures and measuring comprehension: origins and transformations of psychological tests

Silva, Maria Cecilia de Vilhena Moraes 16 June 2010 (has links)

No. of bitstreams: 1 Maria Cecilia de Vilhena Moraes Silva.pdf: 1246481 bytes, checksum: b36c2aeff72f55fcdd6467b0a7b3dc27 (MD5) Previous issue date: 2010-06-16 / Since they were created, psychological tests have been used in different contexts to support decisions that affect the life of many people. If they are to be used properly, it is critical to know both their underlying theoretical assumptions and their limitations. This thesis aims to bring to light such assumptions and to demonstrate that psychological tests , as a generic label, is not suited for the broad array of psychological assessment techniques available today. Based on the work of Pierre Bourdieu, who considers scientific knowledge as a social activity and the conformation of scientific fields as stemming from the configuration of the forces that conform it in a given historical period, this thesis investigates the trajectory of Alfred Binet and Francis Galton, two important actors of the psychological assessment field, considering the personal, social and historical context of their work, and the influence of their contributions to the subsequent conformation of this field. The differences between projective techniques and psychometrical tests are highlighted and the implications of considering both as psychological tests for the conformation of the psychological assessment field in Brazil, today, are discussed. A few issues regarding the education of qualified psychologists for the proper use of these techniques are also considered / Desde sua criação, os testes psicológicos têm sido usados em diferentes contextos, subsidiando decisões que afetam a vida de muitas pessoas. Seu uso adequado tem, como condição fundamental, o conhecimento de seus pressupostos teóricos e de suas limitações. O objetivo deste trabalho é explicitar tais pressupostos e demonstrar que o rótulo genérico testes psicológicos é inadequado para abrigar a diversidade de instrumentos do exame psicológico existentes. Com base em Pierre Bourdieu, considera-se o conhecimento científico como uma atividade social, sendo a conformação de um campo científico decorrente da configuração das forças que o compõem e de seus respectivos pesos em um dado momento histórico. Procura-se recuperar a trajetória de Alfred Binet e de Francis Galton, dois dos principais atores do campo do exame psicológico, abordando o contexto pessoal, social e histórico em que desenvolveram suas obras, e a influência de suas ideias na conformação posterior do campo. A partir disso, procura-se diferenciar técnicas projetivas e testes psicométricos, discutir as implicações de considerá-los sob o mesmo rótulo na conformação do campo do exame psicológico no Brasil de hoje e apontar aspectos importantes da formação do psicólogo para o uso adequado desses instrumentos

Les néomalthusiens français et les sciences biomédicales (1880-1940) / The French neo-Malthusians and bio-medical sciences (1880-1940)

Hello, Eric 09 December 2016 (has links)
Le néomalthusianisme est un courant de pensée qui réunit des pédagogues, des médecins, des anthropologues et des militants féministes et anarchistes. Sa réflexion et son action ont une dimension politique, économique et scientifique. Son projet est une transformation profonde des sociétés humaines par la limitation des naissances afin d'aboutir à une meilleure organisation sociale, capable de répondre à l'aspiration légitime des êtres humains au bonheur. Les moyens pour atteindre cet objectif sont la généralisation de la prophylaxie anticonceptionnelle qui comprend les techniques contraceptives et l'avortement. Le mouvement néomalthusien a été particulièrement actif en France, des années 1890 à la veille de la Seconde Guerre mondiale. Il a également soulevé de nombreuses oppositions et a été activement combattu, notamment après la Première Guerre mondiale. S'intéressant au nombre des naissances, le néomalthusianisme souligne l'incompatibilité entre l'augmentation exponentielle de ce dernier et la possibilité pour les membres composant une collectivité de disposer du nécessaire afin d'atteindre le bonheur.De ce fait, le néomalthusianisme français est inséparable de l'eugénisme, thème central dans l'histoire de ce mouvement, de son émergence à ses derniers développements dans les années 1930. Le présent travail a pour objectif de tracer un portrait synthétique inédit du néomalthusianisme français en privilégiant son rapport aux sciences biomédicales et à la culture scientifique. [...] / Neo-Malthusianism is a line of thought which gathers education specialists,doctors, anthropologists and women's and anarchist activists. Its reflexion and its actionhave a political, economic and scientific dimension. Its project is to deeply transformhuman societies through birth control in order to reach a better social organisation, likelyto meet human beings’ legitimate aspiration for happiness. The means implemented toreach this goal are the generalisation of contraceptive prophylaxis, which includescontraceptive methods and abortion. The neo-Malthusian movement was particularlyactive in France, from the 1890ies to the eve of World War II. It has also met with strongopposition and was actively fought, noticeably after World War I. Observing the number ofbirths, neo-Malthusianism points how incompatible the exponential increase of births iswith the possibility for the members of a given community to have what they need to reachhappiness. Hence, French neo-Malthusianism is inseparable from eugenics, which is acentral theme in the history of this movement, from its emergence to its last developmentsin the 1930ies. The objective of the present work is to draw a new and previouslyunpublished synthetic portrait of this movement, focussing on its link to bio-medicalsciences and scientific culture. [...]
