Rational expectations and the service of public debt: a recursive approach

This paper uses dynamic programming to study the time consistency of optimal macroeconomic policy in economies with recurring public deficits. To this end, a general equilibrium recursive model introduced in Chang (1998) is extended to include govemment bonds and production. The original mode! presents a Sidrauski economy with money and transfers only, implying that the need for govemment fmancing through the inflation tax is minimal. The extended model introduces govemment expenditures and a deficit-financing scheme, analyzing the SargentWallace (1981) problem: recurring deficits may lead the govemment to default on part of its public debt through inflation. The methodology allows for the computation of the set of alI sustainable stabilization plans even when the govemment cannot pre-commit to an optimal inflation path. This is done through value function iterations, which can be done on a computeI. The parameters of the extended model are calibrated with Brazilian data, using as case study three Brazilian stabilization attempts: the Cruzado (1986), Collor (1990) and the Real (1994) plans. The calibration of the parameters of the extended model is straightforward, but its numerical solution proves unfeasible due to a dimensionality problem in the algorithm arising from limitations of available computer technology. However, a numerical solution using the original algorithm and some calibrated parameters is obtained. Results indicate that in the absence of govemment bonds or production only the Real Plan is sustainable in the long run. The numerical solution of the extended algorithm is left for future research.

De touch: extending service channels in an airport through touch technologies

This project aimed to create a communication and interaction channel between Madeira Airport and its passengers. We used the pre-existent touch enabled screens at the terminal since their potential was not being utilised to their full capacity. To achieve our goal, we have followed an agile strategy to create a testable prototype and take advantages of its results. The developed prototype is based on a plugin architecture turning it into a maintainable and highly customisable system. The collected usage data suggests that we have achieved the initially defined goals. There is no doubt that this new interaction channel is an improvement regarding the provided services and, supported by the usage data, there is an opportunity to explore additional developments to the channel.

Proposta Curricular para Educação infantil: (re) significando saberes docentes

The theory contemporary in the field of early children education, as well the legal discourse and official texts valid in our country point to the need for systematization of proposals pedagogic / curriculum in institutions, built and carried out by subjects that act as factor of assurance care quality. Quest us about what knowledge are required to teachers in developing a proposed curriculum for children education. Defined as an object of study, the knowledge teachers necessary for the development of a proposed curriculum for children education. As goals, assume: investigate teachers knowledge necessary for the development of a proposed curriculum in a Public Institution for children education and contribute to the (new) meaning on the part of teachers, knowledge needed to build a proposed curriculum for children education. Assuming the principles of the paradigm of qualitative research, we have developed a research institution of a children education Network Public Hall of Ceará-Mirim-RN, which serves children of four and five years old (preschool) with the participation of 17 teachers and two supervisory (teachers) that institution - subject of our research. Therefore, we have adopted the principles of action research, according to which the knowledge gained through research should build so shared / dialogue in the relationship between researcher and participants, what is the implementation of an effective action formative. As the search procedures developed observations no-teaching participants in the meetings and activities of the classroom; semi-structured interviews (individual and collective) with teachers and supervisors; analysis of school documents and participant observation in the seminars of studies reflective. The latter is implemented as key moments of speech and thought, and finally to (new) meaning of knowledge, the subject of the research-action. For these knowledge, the systematization of the register built was developed based on the principles of analysis of Content that guided us to the definition of two categories 1) knowledge teachers concerning conceptions of curriculum / proposed curriculum and 2) knowledge teachers concerning specifics of children education. From these were built subs representing thematings more specific and significant, among the many that emerged in the analysis: 1.1) Definitions of curriculum and curriculum proposal; 1.2) The subjects makers / implementing a curriculum / proposed curriculum; 1.3) elements constituting a curriculum / proposed curriculum for children education and 2.1) Functions of children education and conception of child; 2.2) The space of the play in the organization of routine. Under the intervention could significant advances with regard to (new) meaning of such knowledge from the subjects, with major disruptions to their original designs. These are presented and reflected in this work. In front of this movement, transformation, made the need for a permanent work in the context of the institution of in-service training, or mediated by pedagogical coordinator or other to assume this role with teachers, in order to provide the development and effectiveness of proposed curriculum consistent and contextualized in practice effective with the children concrete envisage the service to their specificities and a quality education

Política de formação de professores: uma leitura a partir da análise do programa especial de formação de professores para a educação básica PROEB/UFMA

Study of Teacher Education Policy: a reading from the analysis of Programa Especial de Formação de Professores para a Educação Básica Proeb - aims to analyze the initial teacher training developed by the Universidade Federal do Maranhão - UFMA. Proeb is a policy of in-service training of teachers, formulated and implemented in the context of current educational policies for basic education. This work assumes that the guidelines developed in the last decades of the twentieth century are linked to international organizations that spread in Latin America continent a homogeneous model of training which has as main features to be held in service through the mode the distance and the school as a leading locus. In Brazil, these guidelines are supported on the Law of Directives and Bases of National Education No. 9.394/96 and Report 09/2001, which deals with the Syllabus Guidelines for the formation of Basic Education Teachers. To carry out the study was taken as reference, the syllabus developed for the deployment of Proeb from 1998 to 2002, specifically the proposal operationalized in the Degree Course of Mathematics in the city of Vitória do Mearim in Maranhão. To conduct the study, it was used literature as a way to deepen understanding, clarify and aim the conceptual aspect of the object researched. The documental research was consisted in the analysis of legal documents concerning the reform of education policies, teacher training and pedagogical project Proeb/UFMA and, finally, the semi-structured interviews were used to allow a better understanding of the subjects involved with research. The data analysis has shown that the curriculum designed to operationalize the course of undergraduate mathematics Proeb/UFMA, despite having guidelines that point to the separation of theory/practice dichotomy and establish as a principle work as an educational principle, has an disciplinary curriculum organization that reinforces the instrumental view of the syllabus, not enabling in practice, the execution of their initial proposal. Concerning to the view of graduates on the course, they highlight the weaknesses of the course, but also evidence that it has allowed an improvement of initial training, through the disciplines of the common core syllabus of courses and special training. It is possible seeing in graduates words, that the course have had repercussions in their teaching and improving their integration into the labor market and in the community of Vitória do Mearim. Overall, these developments have indicated evidence of teacher professionalization, although they are incipient. The work has shown that for the professionalization of teachers is introduced, the syllabus of undergraduate teacher education must overcome the traditional view of syllabus and implement contextualized curricula in a multidisciplinary approach involving, in equal proportions, the general education and training specific course. Accordingly, it is believed in need to review the role of the University in the formative process, as well as recovering as part of educational policies, the omnilateral size of teacher education

Ensino de matemática pelo rádio (1950 1970): uma história falada e um documentário didático

This study aimed to describe and analyze aspects of the historical course of teaching Mathematics by Radio Experiences in Rio Grande do Norte, between the decades from 1950 to 1970 in order to organize a documentary (CD-ROM) containing information about Mathematics studied by Radio who have experienced it. In this, we use qualitative research. We seek support in the theoretical framework of cultural history and memory researchers as Certeau (1998), Chartier (1990), Le Goff (2008), Thompson (2002) and Peter Burke (2004). Moreover, we take the elements of oral history. We focus on the teaching of literacy and the primary of the Radio schools in two rural communities - Logradouro and Catolé - who are currently part of the city of Lagoa Salgada (RN) and, with respect to the Junior High School, we stopped in the Course of Madureza at Radio. We used as written sources, especially the documents found in the General Archives of the Archdiocese of Natal (RN) and the employees assigned by the participants of the survey. Our sources come from the oral testimonies of pupils and monitors Lagoa Salgada City, teachers, broadcasters and technicians of Rural Support Service (SAR) Natal (RN). In this study, we identify the geometry Cubação social practices of Lagoa Salgada students. Also identified in the research material, the Global Method with the pedagogy of Paulo Freire, that guided the production of lessons in literacy and primary courses. Content in Mathematics, we find traces of the trend-Empirical activist. In the course of Madureza, there was a tendency formal technique Fiorentini (1995). Finally, as a result of this study, organize and present a documentary (CD-ROM), along with the analysis of this study, containing the history of Mathematics teaching by Radio, from the speech of those who experienced Radio, emphasizing the methodology teaching developed in class, that serves as a reference material for students, professors and researchers.

De prático à profissional da matemática: que saberes se constituem em um processo de formação inicial de professores em serviço?

O estudo teve como objetivo investigar as mudanças ocorridas nas/das práticas dos professores-alunos a partir do ingresso em um curso de formação inicial de professores em serviço. Para tal, foi realizada uma pesquisa qualitativa, na modalidade estudo de caso, com dados coletados a partir de entrevistas semi-estruturadas realizada com quatro professores alunos do curso de Licenciatura Plena em Matemática da Universidade Federal do Pará, que estão atuando em sala de aula na Rede Pública Estadual de Ensino. Foram obtidas consideráveis informações que permitiram analisar o entendimento dos sujeitos participantes sobre as mudanças e os saberes construídos e/ou em construção ao longo do curso de formação. Realizamos entrevistas com quatro professores-formadores que estiveram trabalhando com disciplinas especificas da Licenciatura em Matemática na perspectiva de destacar o papel fundamental desse sujeito no processo de formação. Os resultados apontam que, apesar dos fatores que interferem na construção do saber sistematizado, houve mudanças significativas nas/das práticas docentes dos professores-alunos a partir dos saberes construídos num processo de formação inicial. Concluiu-se que estes resultados apontam para a importância da formação inicial para o exercício da prática docente.

Temas capitais da educação a distância: nós e entrenós que tecem a rede da formação de professores

Este trabalho é sobre a prática de professores de matemática que atuam na educação de jovens e adultos (EJA). Trata-se de uma pesquisa qualitativa, cujo objetivo é identificar, por meio das falas dos professores, os saberes por eles produzidos em sua prática docente na EJA. Para a construção dos dados, realizamos entrevistas semi-estruturadas com seis professores de matemática da EJA e a aplicação de questionários para 48 alunos de uma escola do município de Belém/Pará. Dos diálogos que mantivemos com os professores de matemática da EJA emergiram saberes experienciais que desenvolvidos em sua prática na EJA. Os saberes experienciais dizem respeito ao uso de linguagem e metodologias adequadas aos alunos, à contextualização dos conteúdos matemáticos, ao resgate social dos alunos, entre outros. Por meio de suas experiências, os professores reelaboram e adaptam seus saberes com base nas peculiaridades de seus alunos da EJA e na reflexão que fazem sobre suas próprias práticas. As falas dos professores de matemática evidenciam sua insatisfação com os conhecimentos recebidos em sua formação inicial para ensinar na EJA, o que os faz manter em suas práticas, um constante processo de reflexão e auto- formação para atuar nessa modalidade de ensino. Para tanto, é importante que os professores estabeleçam, entre si, relações de parceria, tendo em vista a melhoria do ensino para os alunos da EJA, o que pode contribuir com a implementação do projeto político pedagógico nas escolas da EJA.
