14. The impact of daycare attendance on Math test scores for a cohort of 4th graders in Brazil
We estimate the impact of having attended center-based daycare institutions during early childhood on Math test scores at the 4th grade of elementary school. Because enrollment in daycare centers may depend on unobservable character- istics of the family and the child, we build and estimate a structural model of endogeneous choice of school to deal with the

15. HISTÓRIA DA MATEMÁTICA NO ENSINO FUNDAMENTAL: usos em sala de aula pelo professor de matemática da rede municipal de Aracaju/Se. / HISTORY OF MATHEMATICS IN ELEMENTARY SCHOOL: Uses classroom math teacher at the municipal Aracaju / Se.
This article presents the results of a survey whose aim was to identify whether or how the Mathematics teachers of municipal schools in Aracaju make use of the History of Mathematics to deal with mathematical contents on the final years of Junior High School. In order to accomplish such a task, first it was identified the subjects through the intersection be

16. A função exponencial no caderno do professor de 2008 da Secretaria do Estado de São Paulo, análise de atividades realizadas por alunos da 2 série do ensino médio
This work arms is to analyze whether the activities presented in the Teachers Book contribute to the students on not understanding about the exponential function, and whether on not the students can make changes in the register of semiotic representation, according to Duvals theory (2003). We also analyze if there is a variable approach in this book accordin

17. Um problema de fronteira livre para um sistema eliptico-hiperbolico : uma aplicação ao crescimento de tumores / A free boundary problem for an elliptic-hyperbolic system : an application to tumor growth
In this dissertation we detail the analysis done in the article by X. Chen, A. Friedman, A free boundary problem for an elliptic-hyperbolic system,: an application to tumor growth, SIAM J. Math. Anal. 35, 2003, which considers a free boundary value problem for an elliptic-hyperbolic system of partial differential equations related to the Hele-Shaw problem. T

18. FUNCTIONS OF PRODUCTION MAIZE AND BEANS CROPS, THROUGH AN EXPERIMENTAL AND SIMULATED STUDY / FUNÇÕES DE PRODUÇÃO DAS CULTURAS DE MILHO E FEIJÃO ATRAVÉS DE ESTUDO EXPERIMENTAL E SIMULADO
The development of math models can available a tool to estimate and understand the behavior of the system in face of diferent situations, helping in the decision-making process, through a simplified representation of reality, allowing to simulate several scenes and to estimate the different action courses impact about the production systems, helping in the a

19. Task and delay of reinforcement effects on mathematical questions solution behavior among children with or without ADHD / Efeitos de atraso e tarefa na resolução de problemas matemáticos em crianças com e sem TDAH
The Attention Deficit Hiperativity Disorder (ADHD) has been related to self-control. In behavior analysis, self-control/impulsivity situations have been studied using alternatives differing in reinforcer delay and magnitude. Studies with ADHD children have shown that they have a stronger preference for immediate reinforcers, in comparison to children without

20. As contribuições das políticas de avaliação educacional em larga escala : o caso da avaliação de aprendizagem na Bahia.
The present study dealt with the contributions of educational evaluation public policies to elementary public schools. It focused on the Student Assessment Project (AA) implemented by the State of Bahia-Brazil during the 1999-2004 period (first tests administered in 2001). In the context of this investigation, contributions were comprised of elements of eval

22. MODELAGEM DE CARGA EM SISTEMAS DE ENERGIA ELÉTRICA: MODELO MATEMÁTICO E SUA VALIDAÇÃO COM TESTES DE CAMPO / ELECTRIC POWER SYSTEMS LOAD MODELING: A MATH MODEL AND ITS VALIDATION WITH CASE STUDIES
Neste trabalho é proposta uma nova metodologia para a modelagem estática de carga em Sistemas Elétricos de Potência. A ferramenta proposta visa à estimação dos parâmetros dos modelos exponencial e polinomial (ZIP) relativos às potências ativa e reativa da carga com as variações estáticas de tensão. Estes parâmetros são determinados a partir d

24. Comportamento complexo na formação de bolhas de ar em líquidos / Complex behaviour in air-liquid bubble formation
We have investigated the air bubble formation in viscous fluid with some control parameters. We have characterized the sistem using the air flow and the length of the hose that connects the air flow control system and the injector nozzle as control parameters. The hose corresponds to a system dissipative element. We have found period adding routes with and w
