Por que as cooperativas agropecuárias e agroindustriais brasileiras estão falindo?

Este ar tigo evidencia as contradições do Modelo Cooperativista brasileiro em relação ao Modelo Original. Trata- se de incoerências intrínsecas na formação do movimento cooperativo, nos princípios para a sua condução ideológica, bem como na regimentação e operacionalização estatutária. A partir desses desacertos, o artigo mostra as restrições para o exercício da autogestão. Também sugere mudanças nas leis cooperativistas vigentes, propícias ao exercício da participação dos associados no processo decisório.

A participação de Conselheiros Municipais de Saúde: solução que se transformou em problema?

A proposta de controle social instituída pela constituição abriu perspectivas para uma prática democrática ímpar no setor saúde. O Sistema Único de Saúde utiliza o Conselho Municipal de Saúde (CMS) como meio de cumprimento do princípio constitucional da participação da comunidade para assegurar o controle social sobre as ações e serviços de saúde do município. O CMS tem competência para examinar e aprovar as diretrizes da política de saúde, para que sejam alcançados seus objetivos. Ao atuar na formulação de estratégias, o Conselho pode aperfeiçoá-las, propor meios aptos para sua execução ou mesmo indicar correções de rumos. em Botucatu (SP), o CMS existe desde 1992 e nossa proposta foi analisar a participação dos conselheiros e sua representatividade. Para esse propósito, utilizamos uma abordagem qualitativa que permitisse uma aproximação e o conhecimento daquela realidade. Os resultados mostraram, entre vários aspectos, que, em média, metade dos conselheiros titulares e um terço dos suplentes comparecem às reuniões. Além de interessados, esses conselheiros trazem reivindicações ou sugestões do grupo que representam, considerando boa a repercussão dessas reivindicações, porém nem sempre obtêm respostas satisfatórias, pois algumas decisões são tomadas fora do âmbito do conselho; percebem dificuldade de integração entre os serviços de saúde; a própria organização das reuniões dificulta a participação e, muitas vezes, a reunião apenas aprova pacotes ministeriais que devem ser implementados. Ouvir os conselheiros permitiu levantar problemas que precisam ser enfrentados e, com isso, fazer avançar o processo democrático, ou seja, um desafio para a vida.

Educação superior no século XXI e a reforma universitária brasileira

Procura-se mostrar que a adequação desse sistema para o enfrentamento dos desafios da sociedade do conhecimento, em um país como o Brasil, deve necessariamente resolver três questões: a modernização do sistema, o efetivo aprimoramento da qualidade da educação brasileira em todos os níveis, graus e modalidades e a democratização do ensino promovendo a inclusão social.

Analytical and Monte Carlo approaches to evaluate probability distributions of interruption duration

Regulatory authorities in many countries, in order to maintain an acceptable balance between appropriate customer service qualities and costs, are introducing a performance-based regulation. These regulations impose penalties-and, in some cases, rewards-that introduce a component of financial risk to an electric power utility due to the uncertainty associated with preserving a specific level of system reliability. In Brazil, for instance, one of the reliability indices receiving special attention by the utilities is the maximum continuous interruption duration (MCID) per customer.This parameter is responsible for the majority of penalties in many electric distribution utilities. This paper describes analytical and Monte Carlo simulation approaches to evaluate probability distributions of interruption duration indices. More emphasis will be given to the development of an analytical method to assess the probability distribution associated with the parameter MCID and the correspond ng penalties. Case studies on a simple distribution network and on a real Brazilian distribution system are presented and discussed.

Transmission-expansion planning using the DC model and nonlinear-programming technique

The paper presents a constructive heuristic algorithm (CHA) for solving directly the long-term transmission-network-expansion-planning (LTTNEP) problem using the DC model. The LTTNEP is a very complex mixed-integer nonlinear-programming problem and presents a combinatorial growth in the search space. The CHA is used to find a solution for the LTTNEP problem of good quality. A sensitivity index is used in each step of the CHA to add circuits to the system. This sensitivity index is obtained by solving the relaxed problem of LTTNEP, i.e. considering the number of circuits to be added as a continuous variable. The relaxed problem is a large and complex nonlinear-programming problem and was solved through the interior-point method (IPM). Tests were performed using Garver's system, the modified IEEE 24-Bus system and the Southern Brazilian reduced system. The results presented show the good performance of IPM inside the CHA.

Estudio radiográfico do desenvolvimento da dentição permanente de crianças brasileiras com idade cronológica variando entre 84 e 131 meses.

With the help of orthopantomograms we analyse the tooth development beside body weight and height from Brazilian healthy boys and girls. So, their dental age were compared to their chronological age. The results of this investigation, according to the methodology employed, indicated that: 1. girls showed accelerated formation of permanent teeth and mean values of dental age higher than boys; 2. the mean values of dental age in girls were higher than their chronological age in all groups; 3. the teeth development stages were appropriate in assessment of the degree of physiological maturity of a growing child.

Implantação do pilar ruju Botucatu na UNESP para integração ao Sistema Geodésico Brasileiro

The objective of this work was to implant a geodesic pillar in the campus of Botucatu (Rubião Júnior) of the São Paulo State University (UNESP), using active stations of the Brazilian Net of Continuous Monitoring (RBMC) as reference, aiming at inclusion in the Brazilian Geodesic System (BGS). In the planning of the trace, some aspects of the pillar optimization were considered: the field evaluation, the equipment Receiver GPS Topcon Hiper GGD and the net RBMC were used to trace the height, and the Topcon Tools 6.04 version software was use for the data processing, the ambiguity solution, as well as the treatment of injunctions during the column adjustment. The obtained results allowed the implantation of a more accurate pillar then 1ppm compatible to the RBMC net, meeting the specification of IBGE.

Produção científica na faculdade de filosofia, ciencias e letras de ribeirao preto-usp: Apliçãcao do índice de hirsch

In this work, an analysis of scientific bibliographic productivity was made using the Faculdade de Filosofia, Ciencias e Letras de Ribeirao Preto, Universidade de Sao Paulo (FFCLRP-USP) as example. It is a special Institution in the Brazilian University system which encompasses four important areas of knowledge (fields of concentration) in natural, biological, humanities, and social areas. It is composed by four departments which offer altogether eight undergraduate courses: 1) Psychology, 2) Pedagogy, 3) Chemistry, 4) Biology, 5) Medical Physics, 6) Biomedical Informatics, 7) Sciences of Information and Documentation and 8) Mathematics Applied to Business and six graduate programs leading to M.S. and Ph.D. degrees. Moreover, when analyzing the different courses of FFCLRP, they represent typical academic organization in Brazil and Latin America and could be taken as a model for analyzing other Brazilian research institutions. This analysis was made using: 1) the total number of papers (indexed in Curriculum Lattes database), 2) the number of papers indexed by Thomson ISI Web of Science database, and 3) the Hirsch (h-index). Bibliometric evaluations of undergraduate courses showed a better performance of the courses of Chemistry (P < 0.05), Biology (P < 0.05) and Medical Physics (P < 0.05) when compared to the Pedagogy, Sciences of Information and Documentation (P < 0.05) and Psychology (P < 0.05). We also analyzed the scientific output of the six graduate programs of FFCLRP-USP: 1) Chemistry, 2) Physics Applied to Medicine and Biology, 3) Entomology, 4) Compared Biology, 5) Psychology, 6) Psychobiology. The graduate programs in Psychobiology, Chemistry, Physics Applied to Medicine and Biology, Compared Biology, and Entomology presented very similar results, concerning the assessment of the three indexes. The graduate program in Psychology presented a lower h-index (P < 0.05) and had fewer papers indexed by the ISI (P < 0.05) when compared to the other graduate programs. The worse performance of the psychology program, pedagogy, sciences of information and documentation, psychology courses may be associated to the limited coverage of ISI database and some particular characteristics of this field of concentration.

¿Inestabilidad o estabilidad en la política brasileña? Partidos políticos y presidente de la República contra la incertidumbre

This article examines what political scientists think of the Brazilian political system, especially in regard to the relationship between the executive and legislative branches. There are two opposing camps of scholars who focus on how political parties behave in the Chamber of Deputies. While the first defends a political system that produces undisciplined representatives, the second supports a legislative organization that produces disciplined politicians.

Plano municipal de saúde: Análise do instrumento de gestão

Among planning instruments used by manager instances of Brazilian Health System it pointed the Health Municipal Plan (PMS) that should be built collectively showing political intentions, directresses, priorities, objectives, goals framework, estimative of resources and need costs to get the goals of the health sector. The aim of this work was to analyze the plans in relation to attendance of legal requirements which manage the Brazilian Health System, its constitution and showing of essential items. The study included three municipalities form São Paulo State. It was used the documental analysis as research technique. Near all plans showed an analysis of situation with detailed descriptions of general situation of municipality, and only one of them realized critical analysis of their epidemiological data; the financial income applied on health was decrypted by only one municipality. About programming, all municipalities described the main problems and its solutions. Although they had goals framework, the question about cost estimative to get the goals was not approached. Any municipality showed an annual review, being one of them delayed over than two years. It was observed no participation of Municipal Health Council on elaboration and review of plans. It was concluded that there was a deficiency in the plans analyzed. It's necessary to execute continuing education with managers in relation to importance of systematic elaboration of plans and to incentive the promotion of active participation of Municipal Health Council promotion of aiming to became true the social control of health actions.

Influência da combinação de dados GPS e GLONASS no georreferenciamento de imóveis rurais

The land question has been a widely discussed topic in Brazil, regarding land tenure. Law No. 10.267/01 was a major breakthrough for the agrarian issue. Since then on all rural properties must be georeferenced to the Brazilian Geodetic System (BGS). Therefore, satellite positioning and conventional methods are extensively used. Changes have been occurring in satellite positioning systems due to the addition of new signals in GPS (Global System Positioning), restructuring of GLONASS (Global Orbiting Navigation Satellite System), and the new systems like Galileo and Compass as well. To evaluate the effects of combining GPS and GLONASS data, several batches of processings were performed on different configurations. The data processing was performed to determine the coordinates of points of basic support and those materializing the neighborhood of the rural properties. As a result, it was found that the use of accurate ephemeris in transporting coordinates to support points has no significant influence, since transportation with broadcast ephemeris also meets the accuracy requirements for the Standard Technique for Georreferencing Rural Properties. On the other hand, when GPS and GLONASS data were used, such combination provides the best results. In the case of neighboring points, the use of GPS and GLONASS data is also recommended because such data meet the precision requirement and showed better results than those from where data were processed separately.
