This paper is the result of discussions held during the initial research on ways of reading and reading activities, to obtain the title of the Ph.D. graduate program in Education at UNESP - Marilia. The paper seeks to rethink the practice followed the reality historically constructed as reference, creating a dialectic movement, and a constant construction, and the overcoming of it. In this perspective, we approach possible practices that can enhance the student's prior knowledge, and from it, to propose ways of action that lead to the development of the subject through the processes of teaching and learning of reading in school. From the study of actions that are agreed as reading practices, the study proposes to work with the Reading Strategies to promote the development of the individual. Among the different results that have been announced in the research, we highlight the need for conscious mediation of the teacher in the act of teaching reading and conscious participation of the student in the process. Partial results give evidence to confirm the hypothesis that: intentional actions are driving the learning of children in activity in the classroom, considering their experiences and choices of the teacher as mediator in the process. Students in third grade of elementary school are the subjects of research, theory and practice. The researcher is the mediator and proposer of the actions based on microgenetic research.

The article presents preliminary data of a survey that aimed to investigate the beliefs of children and adolescents about not learning. A total of 80 students, aged 6 to 16 years participated of the study. Among the participants, 20 are 6 years old, 20 are 9, 20 are 12 and 20 are 16 years old. As methodological tool, it was asked the participants to draw a person that learns and another one that doesn’t learn. Data was analyzed according to the Piagetian perspective for the construction of social knowledge. The main results indicate that a significant part of the participants tend to blame the students for the result of no learning. This indicates that students are able to consider the amplitude of different dimensions of social phenomena only partially. When considering the level of understanding of social reality, it was observed that, even at older ages, participants have a very basic notion of the social world.

This study aimed to verify the partial information literacy of librarianship undergraduates with regard to ethical and legal issues related to the use of information and compare with the standards of ACRL (2000). To this end, we applied an electronic questionnaire with 230 students from fifteen schools of Library science in southeastern Brazil. From the results it was realized that the standardization of reference, participants showed a performance below expectations, possibly compromising the recovery of a document by others. In the other questions that addressed issues regarding copyright and intellectual property, the majority of participants have shown that knowledge, behaviors and attitudes appropriate in relation to this aspect.

This paper aims to provide guidelines for the development of communication strategies and relationship to a Private Institution of Higher Education (PIHE), having as initial activity of this process the definition and distinction of its various stakeholders. Currently, it has become necessary due to changes the scene of higher education has been through. In general, competition is greater, the demands of customers increased, causing the university management to take new directions in order to plan the activities in the most possible professional way. The study enables the public to identify needs and preferences of each group, allowing the creation of communication strategies and more targeted and relationships more prosperous and sustainable, making them competitive advantages in the midst of this tumultuous contemporary educational context. Therefore, it was developed a study of public interest of Faculdades Integradas de Bauru - FIB - coupled with the development of a field research, exploratory and descriptive to get subsidies for a project relationship for the various stakeholders of the institution

Our purpose is to show the effects in the predator-prey trajectories due to parameter temporal perturbations and/or inclusion of capacitive terms in the Lotka Volterra Model. An introduction to the Lotka Volterra Model (chapter 2) required a brief review of nonlinear differential equations and stability analysis (chapter 1) , for a better understanding of our work. In the following chapters we display in sequence our results and discussion for the randomic pertubation case (chapter 3); periodic perturbation (chapter 4) and inclusion of capacitive terms (chapter 5). Finally (chapter 6) we synthesize our result

A disseminação de um estilo de vida saudável aliado a um relativo aumento de renda da população brasileira vem provocando um aquecimento no setor de negócios relacionados a atividade física. Nesse contexto, com esse frequente aumento no numero de academias, o cliente tem ampla rede de opção em relação a qual local escolher para desfrutar dos serviços oferecidos. A academia, para acolher o maior numero de clientes, deve oferecer diferenciais em seus serviços. É nessa hora que o profissional de educação física faz grande diferença, através de uma qualificação e capacidade profissional apurada, oferece um serviço de qualidade elevada, posicionado assim a academia em destaque no mercado. Nesse contexto, parece notório que a qualificação profissional, como foco no direcionamento técnico e na especificidade dos serviços oferecidos, não alcança a dinâmica administrativa e de gestão de pessoal. É dentro dessa abordagem que esse trabalho tentará alcançar uma visibilidade dentro do tema e uma abertura para a reflexão sobre a necessidade de aprimoramento teórico na área

Projeto arquitetônico que consiste na construção de um novo Hospital da Mulher em São José do Rio Preto – SP, que foi o primeiro hospital exclusivo para o público feminino da cidade e da região. A ideia era trabalhar apenas com cirurgias limpas ou potencialmente não contaminadas (como cirurgias vasculares, obstétricas, ginecológicas e plásticas), ou seja, com menores riscos de infecção (muito importante principalmente no caso de partos prematuros e do cada vez mais alto percentual de bebês que morrem por causa de infecções hospitalares). Um dos diferenciais do hospital era oferecer ambientes que lembravam uma casa de repouso e instalações hoteleiras, descaracterizando-o de um hospital comum. O investimento em instalações fazia parte do incentivo ao “turismo de saúde” da cidade, que atraia diariamente pacientes de vários municípios e Estados do País. Atualmente o local do antigo hospital é ocupado por uma clínica privada, sendo necessária a construção de um novo prédio, que viria de encontro aos anseios da cidade que, por possuir a Faculdade de Medicina de Rio Preto (FAMERP), vinculada à UNICAMP, ser um pólo regional de saúde com referências à nível nacional teria potencial para abranger uma grande demanda de pacientes diferenciados

Synchronization in nonlinear dynamical systems, especially in chaotic systems, is field of research in several areas of knowledge, such as Mechanical Engineering and Electrical Engineering, Biology, Physics, among others. In simple terms, two systems are synchronized if after a certain time, they have similar behavior or occurring at the same time. The sound and image in a film is an example of this phenomenon in our daily lives. The studies of synchronization include studies of continuous dynamic systems, governed by differential equations or studies of discrete time dynamical systems, also called maps. Maps correspond, in general, discretizations of differential equations and are widely used to model physical systems, mainly due to its ease of computational. It is enough to make iterations from given initial conditions for knowing the trajectories of system. This completion of course work based on the study of the map called ”Zaslavksy Web Map”. The Zaslavksy Web Map is a result of the combination of the movements of a particle in a constant magnetic field and a wave electrostatic propagating perpendicular to the magnetic field. Apart from interest in the particularities of this map, there was objective the deepening of concepts of nonlinear dynamics, as equilibrium points, linear stability, stability non-linear, bifurcation and chaos

Cancer biology is a complex and expanding field of science study. Due its complexity, there is a strong motivation to integrate many fields of knowledge to study cancer biology, and biological stoichiometry can make this. Biological stoichiometry is the study of the balance of multiple chemical elements in biological systems. A key idea in biological stoichiometry is the growth rate hypothesis, which states that variation in the carbon:nitrogen:phosphorus stoichiometry of living things is associated with growth rate because of the elevated demands for phosphorusrich ribosomal RNA and other elements necessary to protein synthesis. As tumor cells has high rate proliferation, the growth rate hypothesis can be used in cancer study. In this work the dynamic of two tumors (primary and secondary) and the chemical elements carbon and nitrogen are simulate and analyzed through mathematical models that utilize as central idea biological stoichiometry. Differential equations from mathematical model are solved by numerical method Runge-Kutta fourth order
