Olhares acerca da construção cotidiana de uma escola do campo

The education of children and youth in the rural areas, with the social movements of struggle for land, returns to a place of relevance and is repositioned on the political agenda. This study aims to analyze the process of development and implementation of a pilot project of schools in the rural area of the city of Araraquara, focusing on the subjects’ perception of the region. We adopted a qualitative ethnographic approach, with the following instruments of data collection: participant observation and semi-structured interviews. It was found that the project which was built through a process of struggle of a community in an adversarial relationship with the municipal government, which itself is struggling in an exercise of cultural emancipation and the construction of citizenship. Thus it finds itself in a habit of cultural resistance and in areas that has its effects on representation and social transformation within the community. Notwithstanding, those who participated in the process of the struggle and implementation have been transformed along the way, salvaging their self-esteem, history and a sense of belonging to a community.

Pediatric Antiphospholipid Syndrome: Clinical and Immunologic Features of 121 Patients in an International Registry

OBJECTIVES. The purpose of this study was to obtain data on the association of antiphospholipid antibodies with clinical manifestations in childhood and to enable future studies to determine the impact of treatment and long-term outcome of pediatric antiphospholipid syndrome.PATIENTS and METHODS. A European registry extended internationally of pediatric patients with antiphospholipid syndrome was established as a collaborative project of the European Antiphospholipid Antibodies Forum and Lupus Working Group of the Pediatric Rheumatology European Society. To be eligible for enrollment the patient must meet the preliminary criteria for the classification of pediatric antiphospholipid syndrome and the onset of antiphospholipid syndrome must have occurred before the patient's 18th birthday.RESULTS. As of December 1, 2007, there were 121 confirmed antiphospholipid syndrome cases registered from 14 countries. Fifty-six patients were male, and 65 were female, with a mean age at the onset of antiphospholipid syndrome of 10.7 years. Sixty (49.5%) patients had underlying autoimmune disease. Venous thrombosis occurred in 72 (60%), arterial thrombosis in 39 (32%), small-vessel thrombosis in 7 (6%), and mixed arterial and venous thrombosis in 3 (2%). Associated nonthrombotic clinical manifestations included hematologic manifestations (38%), skin disorders (18%), and nonthrombotic neurologic manifestations (16%). Laboratory investigations revealed positive anticardiolipin antibodies in 81% of the patients, anti-beta(2)-glycoprotein I antibodies in 67%, and lupus anticoagulant in 72%. Comparisons between different subgroups revealed that patients with primary antiphospholipid syndrome were younger and had a higher frequency of arterial thrombotic events, whereas patients with antiphospholipid syndrome associated with underlying autoimmune disease were older and had a higher frequency of venous thrombotic events associated with hematologic and skin manifestations.CONCLUSIONS. Clinical and laboratory characterization of patients with pediatric antiphospholipid syndrome implies some important differences between antiphospholipid syndrome in pediatric and adult populations. Comparisons between children with primary antiphospholipid syndrome and antiphospholipid syndrome associated with autoimmune disease have revealed certain differences that suggest 2 distinct subgroups.

Isolation of Salmonella enterica Serovar Enteritidis in Blue-Fronted Amazon Parrot (Amazona aestiva)

Avian salmonellosis is a disease caused by bacteria of the genus Salmonella that can cause three distinct diseases in birds: pullorum diseases, fowl typhoid, and paratyphoid infection. Various wildlife species are susceptible to infections by Salmonella, regardless of whether they live in captivity or freely in the wild. The present study verified the presence of Salmonella enterica serovar Enteritidis in three captive specimens of Amazona aestiva. The study involved a total of 103 birds undergoing rehabilitation to prepare for living in the wild, after having been captured from animal traffickers and delivered to the Centrofauna Project of the Floravida Institute in São Paulo, Brazil. This is the first report of Salmonella Enteritidis isolation in A. aestiva that originated from capture associated with animal trafficking; Salmonella was detected during the study by the serologic method of rapid serum agglutination on a plate with bacterial isolate. The antimicrobial profile exam of the isolated samples demonstrated sensitivity to ampicillin, cefaclor, ciprofloxacin, and cloranfenicol. The three samples also presented resistance to more than four antibiotics. The presence of the genes invA and spvC was verified by PCR technique and was associated with virulence and absence of class 1 integron, a gene related to antimicrobial resistance. The commercial antigen for pullorum disease was shown to be a useful tool for rapid detection in the screening of Salmonella of serogroup D(1) in Psittaciformes. New studies on Salmonella carriage in birds involved in trafficking must be performed to better understand their participation in the epidemiologic cycle of salmonellosis in humans and other animals.

Parceria intergeracional e formação docente

O artigo focaliza o potencial formativo da parceria intergeracional na formação docente -inicial e continuada -, tendo por pressuposto a existência de uma cultura profissional específica do magistério (JULIA, 2001), o papel dos professores como produtores de saberes sobre o ensino (SHULMAN, 1986; TARDIF; LESSARD; LAHAYE, 1991), bem como a importância da escola como eixo para a formação docente (NÓVOA, 1999; AZANHA, 2000). São apresentados dados sobre um trabalho formativo que, desde 2006, vem sendo desenvolvido na cidade de Rio Claro, reunindo estudantes do curso de Pedagogia da UNESP e professores dos anos iniciais do ensino fundamental. de acordo com a proposta, futuros professores e professores em exercício atuam como parceiros, em uma relação de colaboração nas atividades docentes. Além da formação profissional dos sujeitos envolvidos, o investimento nessas parcerias tem em vista o desenvolvimento de uma dimensão mais colaborativa no seio da cultura do magistério.

Scientific pedagogy at the end of the 19th century: Some readings and writings in the Portuguese debate

Through the text presented we intend to outline the debate that occurred in Portugal in the transition from the 19th to the 20th centuries. At the time, the imperatives of scientific development had reached education as a basis for the national prosperity. It was believed that Portugal had fallen behind in comparison to the other European countries because it was not capable of constructing a civilization directed by scientific criteria, through the expansion and spreading of culture. The debate over the extension of schools to increasingly broader segments of the population acquires a different meaning when the theorist of Education make use of language from several other areas of knowledge in order to create a mosaic of what has become known, since that time, as the Science of Education.

Time and distance in acceleration of road commercial vehicles

The time and the distance traveled during the acceleration and the velocity retaking are parameters used for the comparison and the project of vehicles. In this paper equations for the calculation of those parameters are presented. Several criteria are presented for the shift gears. It is also verified the occurrence or not of total slip during the acceleration of the vehicle. The theoretical models were implemented in a developed computational system. Such system was applied in a Mercedes-Benz do Brazil sample vehicle, in order to facilitate comparisons between the simulate values and the experimental road tests.

Identification of structural parameters for active vibration control

The study of algorithms for active vibration control in flexible structures became an area of enormous interest for some researchers due to the innumerable requirements for better performance in mechanical systems, as for instance, aircrafts and aerospace structures. Intelligent systems, constituted for a base structure with sensors and actuators connected, are capable to guarantee the demanded conditions, through the application of diverse types of controllers. For the project of active controllers it is necessary, in general, to know a mathematical model that enable the representation in the space of states, preferential in modal coordinates to permit the truncation of the system and reduction in the order of the controllers. For practical applications of engineering, some mathematical models based in discrete-time systems cannot represent the physical problem, therefore, techniques of identification of system parameters must be used. The techniques of identification of parameters determine the unknown values through the manipulation of the input (disturbance) and output (response) signals of the system. Recently, some methods have been proposed to solve identification problems although, none of them can be considered as being universally appropriate to all the situations. This paper is addressed to an application of linear quadratic regulator controller in a structure where the damping, stiffness and mass matrices were identified through Chebyshev's polynomial functions.

The Brazilian architecture in wood and the confrontations with the questions of the environment

Two discussions are imposed to the designers of wood constructions. The first one deals with the technical knowledge to project and execute buildings; the second one is concerned with the preservation of the environment, use of the wood in a sustainable way. The work presents the tendencies of the wood used in the Brazilian habitation architecture characterizing the used woods; how the construction technical solutions have developed and discusses about the necessity of using the wood in a conscious way, knowing its origin and control, sustainable use of the forests resources. It focalizes, mainly, the search of the designers to harmonize the use of the wood and the preservation of the forest biodiversity, when it deals with the native forest.

Model of a game for improving integrated decisions in production management

This paper presents the results obtained with a business game whose model represents the decision making process related to two moments at an industrial company. The first refers to the project of the industrial plant, and the second to its management. The game model was conceived so the player's first decision would establish capacity and other parameters such as quantities of each product to produce, marketing expenses, research and development, quality, advertising, salaries, if purchases will be made in installments or in cash, if there will be credit sales and how many installments will be allowed and the number of workers in the assembly area. An experiment was conducted with employees of a Brazilian company. Data obtained indicate that the players have lack of contents, especially in finances. Although these results cannot be generalized, they confirm prior results with undergraduate and graduate students and they indicate the need for reinforcement in this undergraduate area. © 2012 Springer-Verlag.

Recovery of degraded areas using topsoil in the Amazon rainforest

This study is aimed at evaluating the effect of placing the top soil cover areas, such as tailings degraded by tin mining, in the Amazon rainforest in Brazil. The evaluations of the planting sites occurred in areas where tin mining was carried out, basically planting native trees over a period of seven years. This work did not come from a pre-decreed methodology of experimental design, and data was collected only seven years after planting. Thus, it was not possible to identify all variables that contributed to a better recovery of the areas. Sampling was done about seven years after placing the top soil and is determined: pH, organic matter content, P, K, Ca, Mg, Al, cation exchange capacity (T), base saturation (V%), B, Fe, Zn, Cu and Mn. The native forest species existing at the site were evaluated in relation to height (in meters) and diameter of the base. For all sites where the surface layer of soil was applied, there were significant differences in the growth of native species. A fundamental aspect in the rehabilitation of areas degraded by mining, in general, is the knowledge about the soil where that recovery must be conducted. The specific procedures in the rehabilitation of those areas depend essentially on the physical, chemical, biological and mineralogical properties of the soil, which must present conditions for the adequate development of the plants. The initial idea of implanting a project of recovery of soils degraded by mining in the Amazon Forest emerged from a first visit to the field, carried out in 1998. The conditions of the already mined areas, in comparison to the exuberant forest of the surroundings caught our attention. The mining company that acts in the area had already been trying for some time to implant a plan of recovery of these mining areas, however without reaching any significant positive results. The loss of organic matter is one of the main problems of degraded areas in Brazil. The storage and reuse of a blanket of soil (topsoil) produce excellent results, but most of the miners consider this technique expensive and difficult because of operational costs and the sharp topographical condition of the mine site. Therefore, a research project was elaborated prioritizing the recovery of the soil degraded by the tin mining as a prior step to the recovery activities with native forest species. The formation of a superficial pseudo-horizon that supported the vegetation and the time that it would take for its establishment became the main objective of this research. The objective of this work is to verify the levels of elements and their traces in areas where top soils were applied for the remediation of degraded areas with local re-vegetation. © 2011 WIT Press.
