A teoria democrática e a participação popular : as trajetórias participativas no Recife e em Módena

This work basically achieve three goals. Critically investigate the liberal democratic regime and its historical reformulation, rejecting the popular power and popular self-organization, limiting the entry of normal citizen in decision-making, believing in the market as a mediating body in regulating of the different life spheres of social. Starting from the critical liberal democracy, it discussed the concept of popular participation in the democracy, searching new democratically horizons, where the masses could have the opportunity to make decisions about their own destiny. On the basis of theoretical discussion on participation, we discuss a concrete instrument of participation, the Participatory Budgeting, comparing two participatory experiences in North and South

Resposta de brócolis, couve-flor e repolho à adubação com boro em solo arenoso

Foram avaliados em condições de campo, em solo arenoso, com baixo teor de boro, os efeitos da adubação com cinco doses de boro (0; 2; 4; 6 e 8 kg ha-1 de B na forma de bórax) na produção de brócolis, couve-flor e repolho. O experimento obedeceu a um esquema fatorial com delineamento experimental de blocos ao acaso com três repetições. As adubações orgânica e química, inclusive o bórax, foram feitas no sulco antes do transplantio das mudas e a colheita foi feita entre 63 e 93 dias após o transplantio. A produtividade de brócolis variou de 16,9 a 20,5 t ha-1; a de couve-flor de 21,6 a 29,6 t ha-1 e a de repolho de 40,5 a 46,4 t ha-1. O aumento observado na produtividade de brócolis e de repolho foi linear e o efeito das doses de boro na produtividade de couve-flor foi quadrático, sendo necessários 5,1 kg ha-1 de B para atingir a produtividade máxima de 30 t ha-1. Brócolis e repolho mostraram-se menos sensíveis do que a couve-flor tanto à deficiência quanto ao excesso de boro. No caso da couve-flor, com a aplicação de 2 kg ha-1 ou de 6 kg ha-1 de B houve significativa perda de qualidade do produto.

Atividade microbiana do solo em pomar de laranja em resposta ao cultivo de adubos verdes

Adubos verdes (AVs) são condicionadores do solo utilizados para a melhoria da estrutura e fertilidade do solo. Este estudo avaliou o efeito de Crotalaria spectabilis Roth (crotalária), Cajanus cajan (L) Millsp (guandu) e Brachiaria decumbens Stapf (braquiária) nas propriedades microbiológicas e bioquímicas do solo sob laranjal. As leguminosas foram plantadas nas entrelinhas do laranjal e, após 3 meses, cortadas e lançadas nas entrelinhas. A braquiária, já estabelecida, foi roçada e lançada nas entrelinhas. Após 5 meses, as amostras de solo foram coletadas na entrelinha e na linha, na profundidade de 0-20 cm. O delineamento experimental foi em parcela subdividida. Efeito significativo (p< 0,05%) da aplicação dos AV sobre as contagens de bactérias, as atividades da desidrogenase e nitrificante foram obtidas e aumentaram, em média, de 20, 39 e 190%, respectivamente. O número de fungos diminuiu de 57%. A atividade da urease e a solubilizadora, e os conteúdos de matéria orgânica e umidade não foram influenciados pela aplicação dos AVs. Dentre as plantas, respostas significativas foram obtidas decorrentes do estímulo da atividade da desidrogenase em 57% pelo guandu, da urease em 58% pela braquiária, solubilizadora em 346% pela crotalária e nitrificante em 236% pelo guandu ou braquiária em relação aos demais AVs. Estes resultados sugerem que a aplicação de AVs durante anos consecutivos pode estimular a ação dos microrganismos e melhorar a qualidade do solo.

Resposta de mudas de goiabeira a doses e modos de aplicação de fertilizante fosfatado

O presente trabalho objetivou avaliar o desenvolvimento de mudas de goiabeira em resposta a doses e modos de aplicação de fertilizante fosfatado. As mudas de goiabeira foram transplantadas em conjuntos de vasos (sacos plásticos, 18 x 28 cm) geminados, contendo em cada lado 2,8 dm³ do subsolo de um Argissolo (P resina = 1 mg dm-3), de modo que a metade do sistema radicular ficasse em cada vaso. Usou-se um fatorial 2 x 3 x 2 + 1 (testemunha, sem fósforo), em 5 blocos casualizados. As doses de 70; 140 e 280 mg de P dm-3 de solo, na forma de superfosfato triplo, foram aplicadas de dois modos diferentes com relação ao solo (distribuído em todo o volume do solo ou localizado a 1/3 de profundidade) e dois modos diferentes com relação às raízes (dividindo-se a dose igualmente entre os dois vasos do conjunto ou aplicando-se a dose total em um único vaso). Cem dias após o transplante, verificou-se maior acúmulo de P e maior produção de matéria seca nas plantas que receberam adubação fosfatada. As mudas de goiabeira responderam positivamente à adubação fosfatada, sendo a dose próxima de 100 mg de P dm-3 de solo suficiente para o bom desenvolvimento das plantas. Doses acima de 200 mg de P dm-3 promoveram redução do crescimento das mudas de goiabeira. A disponibilização de fósforo à metade ou a todo o sistema radicular da goiabeira não afetou o suprimento desse nutriente às mudas e tampouco o seu desenvolvimento. A aplicação do adubo fosfatado distribuído em todo o volume de solo no vaso proporcionou maior desenvolvimento do sistema radicular e menor desenvolvimento da parte aérea das mudas de goiabeira, comparado à aplicação localizada do adubo a 1/3 de profundidade.

A Eficácia dos direitos fundamentais nos contratos civis e de consumo: uma teoria contratual baseada na colisão dos direitos ou bens constitucionalmente protegidos

The apparent virtuosity that if could wait of the globalization and the neoliberalism has given signals of deterioration in the contractual relations, especially in contracts of mass consumption, generating innumerable offensive situations to the basic rights and the goods constitutionally protected of the contractors. In the world of today, still that it does not reveal any desire, the individual practically is compelled to contract, for force of necessities and customs completely imposed, mainly in face of the essentiality of the services or agreed to goods. Ahead of as much and unexpected changes in the civil liames and of consumption, dictated for the globalization, it comes to surface the reflection if the private law e, more specifically, the civil law, meet prepared adequately to deal with these new parameters of the economy. The present dissertation has the intention to investigate if the globalization and the consequent neoliberalism, in this beginning of third millennium, will imply to revive of the principles and the basics paradigms of the contracts that consolidated and had kept, for more than two centuries, the liberal State. One notices that the study of this phenomenon it gains importance to the measure where if it aggravates the decline of the social State (Welfare State), with the embrittlement and the loss of the autonomy of the state authority, over all in countries of delayed modernity, as it is the case of Brazil, that presents deep deficiencies to give or to promote, with a minimum of quality and efficiency, essential considered public services to the collective and that if they find consecrated in the Federal Constitution, as basic rights or as goods constitutionally protecting, the example of the health, the education, the housing, the security, the providence, the insurance, the protection the maternity, the infancy and of aged and deficient. To the end, the incidence of constant basic rights of the man in the Constitution is concluded that, in the process of interpretation of the right contractual conflicts that have as object rights or goods constitutionally proteges, in the universe of the globalized perhaps economy and of the neoliberalismo, it consists in one of the few ways - unless the only one - that still they remain to over all deal with more adequately the contractual relations, exactly that if considers the presence of clauses generalities in the scope of the legislation infraconstitutional civil and of consumption, front the private detainers of social-economic power. To be able that it matters necessarily in disequilibrium between the parts, whose realignment depends on the effect and the graduation that if it intends to confer to the basic right in game in the private relation. The Constitution, when allowing the entailing of the basic rights in the privates relations, would be assuming contours of a statute basic of all the collective, giving protection to the man against the power, if public or independently private

Teoria da despesa pública: uma leitura ético-constitucional em busca do possível da reserva

Brazilian law passes through a crisis of effectiveness commonly attributed to the extravagance of fundamental rights and public shortage. However, public finances are not dogmatically structured to solve the conflicts around the limitations of public spending. There are ethical conditioning factors, like morality, proportionality and impartiality, however, these principles act separately, while the problem of public shortage is holistic. Also, the subjectivity of politics discretionary in the definition of public spending, which is supported in an indeterminate concept of public interest, needs material orientation about the destination of public funds, making it vulnerable to ideological manipulation, resulting in real process of catching rights. Not even the judicial activism (such as influx of constitutionalism) is shown legally appropriate. The Reserve of Possible, also presents basic ethical failure. Understanding the formation of public shortage is therefore essential for understanding the crisis of effectiveness of state responsibilities, given the significant expansion of the state duty of protection, which does not find legal technique of defense of the established interests. The premise of argument, then, part of the possibility of deducting minimal model ethical of desire to spend (public interest) according to objective parameters of the normative system. Public spending has always been treated disdainfully by the Brazilian doctrine, according to the legal character accessory assigned to the monetary cost. Nonetheless, it is the meeting point between economics and law, or is in the marrow of the problem of public shortage. Expensive Subjects to modernity, as the effectiveness of fundamental rights, pass necessarily an ethical legal system of public spending. From the ethical principles deducted from the planning, only the democratic principle guides the public spending through the approval of public spending in the complex budget process. In other words, there is an ethical distancing of economic reality in relation to state responsibilities. From the dogmatic belief of insufficiency, public spending is evaluated ethically, according to the foundations of modern constitutionalism, in search of possible of the financial reserve, certain that the ethics of public economy is a sine qua non condition for legal ethics.

O direito fundamental contra a autoincriminação: a análise a partir de uma teoria do Processo Penal Constitucional

The right against self-incrimination is a fundamental right that works in the criminal prosecution, and therefore deserves a study supported by the general theory of criminal procedure. The right has a vague origin, and despite the various historical accounts only arises when there is a criminal procedure structured that aims to limit the State´s duty-power to punish. The only system of criminal procedure experienced that reconciles with seal self-incrimination is the accusatory model. The inquisitorial model is based on the construction of a truth and obtaining the confession at any cost, and is therefore incompatible with the right in study. The consecration of the right arises with the importance that fundamental rights have come to occupy in the Democratic Constitutional States. In the Brazilian experience before 1988 was only possible to recognize that self-incrimination represented a procedural burden for accused persons. Despite thorough debate in the Constituent Assembly, the right remains consecrated in a textual formula that´s closer to the implementation made by the Supreme Court of the United States, known as "Miranda warnings", than the text of the Fifth Amendment to the U.S. Constitution that established originally the right against self-incrimination with a constitutional status. However, the imprecise text does not prevent the consecration of the principle as a fundamental right in Brazilian law. The right against self-incrimination is a right that should be observed in the Criminal Procedure and relates to several of his canons, such as the the presumption of not guilty, the accusatory model, the distribution of the burden of proof, and especially the right of defense. Because it a fundamental right, the prohibition of self-incrimination deserves a proper study to her constitutional nature. For the definition of protected persons is important to build a material concept of accused, which is different of the formal concept over who is denounced on the prosecution. In the objective area of protection, there are two objects of protection of the norm: the instinct of self-preservation of the subject and the ability to self-determination. Configuring essentially a evidence rule in criminal procedure, the analysis of the case should be based on standards set previously to indicate respect for the right. These standard include the right to information of the accused, the right to counsel and respect the voluntary participation. The study of violations cases, concentrated on the element of voluntariness, starting from the definition of what is or is not a coercion violative of self-determination. The right faces new challenges that deserve attention, especially the fight against terrorism and organized crime that force the development of tools, resources and technologies about proves, methods increasingly invasive and hidden, and allow the use of information not only for criminal prosecution, but also for the establishment of an intelligence strategy in the development of national and public security

Resposta de diferentes populações de Digitaria insularis ao herbicida glyphosate

Objetivou-se com estse trabalho avaliar o controle químico de diferentes populações de capim-amargoso (Digitaria insularis) pelo herbicida glyphosate por meio de curva de dose-resposta, além de propor tratamentos alternativos para as populações mais tolerantes. O delineamento experimental foi o de blocos ao acaso, com quatro repetições, em esquema fatorial 5 x 9. As sementes de capim-amargoso foram coletadas em cinco locais: área de produção de grãos da Fazenda de Ensino, Pesquisa e Produção da UNESP, Jaboticabal (SP); área de produção comercial de grãos, localizada nos municípios de Campo Florido-MG e Rio Verde-GO; pomar de laranja, localizado no município de Matão (SP); e área não agrícola sem histórico da aplicação de glyphosate (Jaboticabal-SP). O glyphosate (0D, 1/4D, 1/2D, D, 2D, 4D e 8D, em que D é a dose recomendada de 1,5 kg ha-1 de equivalente ácido) e as suas associações [glyphosate + fluazifop-p-butil (1,5 + 0,25 kg ha-1) e glyphosate (1,5 kg ha-1) com sequencial de diuron + paraquat (0,20 + 0,40 kg ha-1 + 0,2% de surfatante)] foram pulverizados em plantas de sete a oito perfilhos e altura média de 20 cm. As populações de capim-amargoso de Campo Florido e Rio Verde foram consideradas suscetíveis; as de Jaboticabal e Matão, tolerantes; e a da área não agrícola, de sensibilidade intermediária. A associação de glyphosate ao fluazifop ou a sua aplicação com sequencial de diuron + paraquat foram eficazes no controle das populações mais tolerantes de capim-amargoso.

Resposta à inoculação de fungo solubilizador de fósforo em milho

Este trabalho procurou verificar o efeito da adição de duas fontes de fosfato prontamente disponíveis, superfosfato triplo e fosfato solubilizado obtido por via microbiológica e uma fonte não prontamente disponível, apatita de Araxá, na cultura do milho. em adição, foi verificado o efeito da inoculação do fungo Aspergillus niger, solubilizador de fosfato de rocha e da adição de matéria orgânica. Nos tratamentos em que se usou matéria orgânica, houve um aumento de população microbiana total do solo, mas nenhum efeito foi observado na produção e absorção de fósforo pela cultura do milho. Tanto o superfosfato triplo como a apatita de Araxá permitiram resultados mais favoráveis em termos de produção de massa seca e absorção de fósforo pelo milho em relação ao controle (sem fósforo) e à utilização de fosfato solubilizado. Também não se constatou efeito da inoculação de A. niger sobre a solubilização do fosfato de rocha, possivelmente devido à interferência dos microrganismos naturais do solo. O numero de microrganismos e a atividade da fosfatase ácida foram menores no solo fertilizado com superfosfato triplo que com apatita de Araxá.

A relação teoria-prática do curso de formação de professores do campo na UFPA

Ce travail est une reflexion sur les pratiques éducatives dévelloppées par des élèves/professeurs dans le Cours de Formation d Éducateurs de la Campagne, réalisé dans un partenariat entre l Université Fédérale du Pará (UFPA), Le Movimento dos Trabalhadores sem Terra (MST Mouvement des travailleurs sans Terre) et le Programme National d Éducation dans la Réforme Agraire (PRONERA), en ayant comme son objectif stratégique rechercher les éléments facilitateurs de l articulation théorie-pratique dans les procédures méthodologique du Cours, fondé sur Paulo Freire. Nous approfondissons des réflexions sur la production d une proposition d Éducation de la Campagne qui, entre autres éléments, se fonde sur la Pédagogie de l Alternance, spécifiquement en ce qui concerne lês catégories Temps École et Temps Communauté. Dans le procès de recherche, nous utilisons comme ressources les documents écrits (dês projets de cours, des rapports, des journaux de la campagne document qui registre le quotidien des activités et des choses réalisées), et les discours des élèves de l Assentamento Palmares II , pendant et après lê Cours. À l analyse, nous identifions comme éléments facilitateurs de la relations théorie et pratique, le Temps École et le Temps Communauté en créant des opportunités, la rélation de ce qui se caracterise comme praxis (action-refléxion-action), en utilisant la recherche comme moyen d insertion dans la réalité et l´existence de groupe (colectif), ce qui a possibilité la participation colective aux réalisations des pratiques pédagogiques plus significatives dans le procès de Formation d Éducateurs de la Campagne, en ayant comme objectif la contribution dans la formation des sujets réalisateurs de leur histoire

Adrien-Marie Legendre (1752-1833) e suas obras em Teoria dos Números

The present thesis is an analysis of Adrien-Marie Legendre s works on Number Theory, with a certain emphasis on his 1830 edition of Theory of Numbers. The role played by these works in their historical context and their influence on the development of Number Theory was investigated. A biographic study of Legendre (1752-1833) was undertaken, in which both his personal relations and his scientific productions were related to certain historical elements of the development of both his homeland, France, and the sciences in general, during the 18th and 19th centuries This study revealed notable characteristics of his personality, as well as his attitudes toward his mathematical contemporaries, especially with regard to his seemingly incessant quarrels with Gauss about the priority of various of their scientific discoveries. This is followed by a systematic study of Lagrange s work on Number Theory, including a comparative reading of certain topics, especially that of his renowned law of quadratic reciprocity, with texts of some of his contemporaries. In this way, the dynamics of the evolution of his thought in relation to his semantics, the organization of his demonstrations and his number theoretical discoveries was delimited. Finally, the impact of Legendre s work on Number Theory on the French mathematical community of the time was investigated. This investigation revealed that he not only made substantial contributions to this branch of Mathematics, but also inspired other mathematicians to advance this science even further. This indeed is a fitting legacy for his Theory of Numbers, the first modern text on Higher Arithmetic, on which he labored half his life, producing various editions. Nevertheless, Legendre also received many posthumous honors, including having his name perpetuated on the Trocadéro face of the Eiffel Tower, which contains a list of 72 eminent scientists, and having a street and an alley in Paris named after him

Como vão se formando os professores em física e química: embates entre o ser, o ter e o fazer na formação de licenciandos da UFRN sob a perspectiva da teoria das representações sociais

The purpose of this work is to approach and understand the Social Representations (SR) (MOSCOVICI, 2003) about Physics and Chemistry from people who are major in these courses, as well as their Social Representations about teaching . We took as principle that approaching these representations it would be possible to relate their symbolic contents, in order to show how people who are following the first segments of bachelor degree courses in Physics and Chemistry become teachers, taking into account a psychosocial view. Two source of data was used during this research: Free-association Technique FA (ABRIC, 1994); and Multiple Classification Procedure (MCP) (ROAZZI, 1995). The analytical treatment of the collected data from FA was done according to the proposition of Grize, Vergés and Silem (1987 apud ABRIC, 1994, p. 66). MCP data were analyzed through MSA (Multidimensional Scalogram Analysis) and SSA (Singular Spectrum Analysis) methods associated with the Facet Theory (BILSKY, 2003). The discourses of MCP discussing groups at the moment of explanations were studied by Content Analysis as it was proposed by Bardin (1977) and Franco (2005). Indicative of an approach to the relations with knowledge (CHARLOT, 2000), the connections which aroused from the analyses showed that the group of future majors in Physics thought that this scientific field was based on a rationalist conception, influencing the idealization sense of the phenomena to be explained by Physics. Thus, Physics as school content started to require the student of the fundamental and high school to think abstractly as a cognitive skill of learning. The identifying elements observed in the relations between SR about Physics and Teaching aroused from the antagonism between future majors and their teacher, as well as from the speculation between their fundamental and high school students and themselves, mainly when they had to face the act of teaching due to the obstacles imposed by the own educational system, and by the weakness of the initial preparation. The group of future majors in Chemistry, through its discourses, showed these relations when they conceived empiricist Chemistry and said that teaching was the way of transmission of this knowledge, and didactics of Chemistry teaching was the direction to learning through pedagogic methods in order to lead the students to discoveries. The psychosocial contents which were built and showed from the symbolic relations in the studied SR achieved the relation of identity. This relation revealed identifying elements for these people, resulting from the traffic between their condition as students of Chemistry, and as teachers regarding their work, what placed the current relational contents in the teaching space, named as Knowledge changing and Adaptability . In order to study emerging questions in the discussing environment about formation and teaching professionalization, we focused the psychosocial view on this traffic and managed to observe epistemological practical and pedagogic obstacles that limited a configuration of the teaching work as a professional activity, especially from the particular conditions which led the relations of senses to Physics , Chemistry and Teaching ; and Chemistry and Physics as it was seen in this research. Generally speaking, we noted that these obstacles can denounce such obstacles concerning to the pedagogic doings which mainly impair the learning process of fundamental and high school students

Implicações técnicas da vacinação na resposta imune contra o vírus da febre aftosa

Na bovinocultura brasileira, a vacinação contra o vírus da Febre Aftosa (FA) é fundamental para a fase inicial de erradicação da enfermidade. Mesmo a qualidade da vacina tendo controle rígido feito pelos órgãos oficiais, restam variáveis técnicas ainda não monitoradas como manipulação, transporte e conservação pelo consumidor, dose, local e forma de aplicação que interferem na resposta imune, preocupações essas, que direcionam o presente estudo. Assim, pela pesquisa de anticorpos neutralizantes do vírus da FA em placas de microtitulação com cultivo de células BHK-21, foram determinados os títulos, calculados em logaritmo decimal (SN), em soros sanguíneos de bovinos vacinados conforme o protocolo apresentado. No primeiro grupo com 25 animais, a média de SN foi igual a 2,37 e 2,19, respectivamente, 30 e 180 dias após a vacinação, cuja vacina foi manejada por especialista com todos os cuidados técnicos recomendados. Outro grupo com 140 bovinos, distribuídos em 5 fazendas distintas, apresentou média de SN igual a 1,66 e 1,5l depois de 30 e 180 dias após a vacinação, cuja vacina foi manejada sem acompanhamento técnico e por indivíduos não especializados. Finalmente um terceiro grupo com 10 animais, que ficaram sem vacinação, apresentou média de SN igual a 0,82 e 0,81, também 30 e 180 dias após a aplicação do placebo. Assim, só os cuidados com a qualidade da vacina são insuficientes para proporcionar títulos satisfatórios que determinam proteção dos rebanhos contra o vírus da FA, uma vez que a literatura pertinente considera rebanhos com 1,52 de média do SN como tendo 50% dos animais protegidos, e com 1,70 como tendo mais de 70% de proteção, no período de até 7 meses.

O professor e sua formação linguística: uma interlocução teoria-prática

The work in screen constitutes a study of entitled doutoramento THE teacher and your linguistic formation: a dialogue teoria-prática. In him, the researcher, discoursing on subjects that involve the teaching-learning of the verbal language, it focalizes the importance of the linguistic formation for professionals that act in the years you begin of the Fundamental Education. In that perspective, lens to analyze the interrelações among them you know about the teachers, referring to the language (verbal), mobilized in the process teaching-learning of the production of texts written by the students, enrolled in the years you begin of the fundamental teaching. For so much, it developed a research Colaborativa, of qualitative nature, with four partícipes, being three of them teachers of the empiric field, EETB (pointed school for the " Prova Brasil " (2005) as among the ten Brazilian schools with the worst index of revenue discente in the abilities to read, to write and to interpret) and the other (researcher) educational of UERN. The research made use of several methodological procedures, among which stand out: questionnaire, glimpses, reflexive sessions and cycles of reflexive studies, among others. These specific of the Methodology of the Elaboration Conceptual Ferreiriana, adopted in the process of (re)elaboration, for the partícipes of the language concepts, text, textual gender, spoken language and written language. With relationship to the analytic procedures, those were based in contributions of the theory of the formation of concepts, of the Applied Linguistics and of the archaeology of the elect concepts. The results appear that the process of linguistic formation, established through the research colaborativa and of the methodology of the elaboration conceptual ferreiriana, uniting knowledge of the areas of the Education and of the Language, it was productive and he/she reveals a narrow relationship among the acquired knowledge for the partícipes, the (re)organization of the process teachinglearning of the language and the improvement of the productions written by the students of those educational ones
