Democracia participativa e regulação econômica: uma questão de legitimidade

This work presents an analysis about the legitimation of independent regulatory commission`s rulemaking power by participation procedure. It is observed that political and administrative decentralization and fragmentation of State, with the purpose of approaching citizens and provide, more efficiently, the functions acquired by the passage of the Welfare State, leads to a deficit of legitimacy (democratic crisis), which is noticeable in the making of legal norms by directors of independent regulatory commission to regulate specific economic sector. However, we understand that this crisis stems from the observation of the contemporary world from dogmas and legal institutions of the eighteenth century, without their evolution and adaptation to the modern world. The legitimacy must be perceived as the justification of power, relation command /obedience, which, from the Modern State, has the democracy as standard. Therefore, just as the world has evolved and demanded political and administrative decentralization to accompany him, it is necessary to the development of the idea of representative democracy (formal legitimacy) to participatory democracy (legitimacy stuff). Legitimacy is not confused with the legality: as the legality is on observance to internal legal system, the "rules of play"; legitimacy, as inputs to be fed into this system, the selection of the different expectations in the environment. Nevertheless, the legitimacy will take place by legality, through introduction of rational and communicative procedures: procedures get fundamental importance because these will be the means to select the expectations to be introduced in the legal system in order to make decisions more fair, rational and qualified towards society. Thus, it is necessary to its opening to the environment for dialogue with the government. In this context, we try to make an analysis of constitutional norms based on systematic and teleological interpretation of these norms to build these arguments. According to the Constitution of 1988, participatory democracy is a result of the democratic principle (sole paragraph of art. 1 of the Constitution), and it is an expression of citizenship and political pluralism, both foundations of Republic (respectively Art. 1st, inc . V and II of the Constitution), as well as the national consciousness. From another point of view, that principle consists of an evolution in the management public affairs (principle of Republic). The right of interested participate in the rulemaking process derives both the principle of popular participation (part of the democratic principle) and the republican principle as the due process constitutional (art. 5, LIV and LV, CF/88) and the right to petition (Art . 5 °, inc. XXXIV, "a", CF/88), and it is the duty of the State not only be open to participation and encourage it. Ignoring stakeholder involvement in procedures and / or expressions compiled can be causes of invalidation of the rule of law produced by addiction of procedure, motive, motivation and/or because of the administrative act. Finally, we conclude that the involvement of stakeholders in the process of making rules within the independent regulatory commission is the legitimacy and the validity of rules; and that, despite of the expressions do not bind the decision making, they will enter the system as juridical fact, balancing the field of technical discretionary of agencies

Regulação do livre acesso no transporte de gás natural à luz da ordem econômica da Constituição de 1988

In the middle of modern social changes produced by globalization and capitalism, several markets have changed. States have left the direct coordination of these markets (chiefly public utility sector in the form of monopolies), introducing regulation in order to promote competition. These changes have affected natural gas industry by promoting competition as a key factor to the development and the increase of firms in this market. The regulatory reform of natural gas industry ocurred in EUA and Europe Union and it has produced its first results. In Brazilian context, Constitutional Amendment nbr. 09 and Federal Law nbr. 9.478/97 ( Petroleum Law ) opened the natural gas market to a broad range of private economic agents and they finished the monopoly over the industry before managed by Petrobras. The new regulatory framework of Brazilian natural gas industry has designed competition as a central element to the new form of managment of business and contractual relationships of this industry. Among the regulatory instruments, open access regulation in natural gas pipelines is directed to promote competition. The questions arised about its implementation in Brazilian context are studied in the present work, in which it is discussed the constitutional rules and principles are to be applied to the open access regulation within the theme of statal regulation of economy present in constitutional economic order

Relação entre variáveis na regulação do consumo de vacas Holandês × Zebu em lactação sob pastejo em capim-elefante

A análise fatorial de componentes principais (CP) foi usada no exame do relacionamento entre variáveis de um banco de dados da Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) Gado de Leite. As variáveis disponíveis foram relacionadas às vacas (dias em lactação, teores lácteos de gordura e extrato seco total, produção de leite, ordem de lactação, peso vivo e grau de sangue), ao manejo (dia de pastejo, disponibilidade e períodos de descanso da pastagem), ao ambiente (estação do ano, precipitação pluviométrica) e ao alimento (consumo de nutrientes do concentrado e da cana × uréia, consumo de MS de pastagem de capim-elefante, composição química e digestibilidade in vitro da pastagem e concentração fecal de PB, FDN e FDA). O primeiro CP (33,7% da inércia dos dados) representou o uso da suplementação volumosa (cana × uréia) da pastagem em resposta à redução sazonal da disponibilidade e do consumo de capim-elefante. O segundo CP (15,3% da inércia) foi relacionado ao consumo de nutrientes do concentrado. O terceiro CP (8,5% da inércia) representou efeitos do manejo sobre a composição química da pastagem. A interpretação gráfica dos resultados favoreceu a percepção mais dinâmica da intensidade da associação e do antagonismo entre as variáveis contextualizadas no estudo.

Amplificação gênica alelo-específica na caracterização das hemoglobinas S, C e D e as interações entre elas e talassemias beta

INTRODUÇÃO: As hemoglobinopatias resultam de alterações hereditárias, sendo prevalentes em muitas regiões do mundo, mas atingem a população brasileira de forma significativa. Elas são decorrentes de alterações em genes estruturais responsáveis pelo aparecimento das hemoglobinas variantes e/ou em genes reguladores, resultando nas talassemias. A identificação dessas patologias tem sido rotineiramente realizada por procedimentos eletroforéticos, contudo nossa experiência laboratorial evidencia que as mesmas nem sempre apresentam resoluções suficientes para a correta caracterização da mutação. CASUÍSTICAS E MÉTODOS: O propósito deste trabalho foi estabelecer uma metodologia válida para a caracterização das hemoglobinas S, C e D em homozigose ou heterozigose, e suas possíveis interações, baseada na amplificação gênica alelo-específica (PCR-AE) com a utilização de primers sense, antisense e primers que se acoplam na posição do alelo mutante e na respectiva posição do alelo normal. RESULTADOS E DISCUSSÃO: Os resultados evidenciaram a validade dessa metodologia na caracterização das mutações, sendo esse procedimento de fácil realização, reprodutível e possível de ser aplicado em um significativo número de amostras.

Desenvolvimento de sistemas farmacêuticos emulsionados para veiculação gênica

Broadly speaking, the concept of gene therapy involves the transfer of a genetic material into a cell, tissue, or organ in order to cure a disease or at least improve the clinical status of a patient. Making it simple, gene therapy consists in the insertion of functional genes into cells containing defective genes by substituting, complementing or inhibiting them. The achievement of a foreigner DNA expression into a population of cells requires its transfer to the target. Therefore, it is a key issue to create systems able to transfer and protect the DNA until it reaches the target, the vectors. The disadvantages related to the use of viral vectors have encouraged efforts to develop emulsions as non-viral vectors. In fact, they are easily produced, present controllable stability and enable transfection. The aim of this work was to develop an emulsion for gene therapy and evaluate its ability to compact nucleic acids by the development of a complex with the plasmid pIRES2-EGFP. The first step was to determine the Hydrophilic Lipophilic Balance (HLB) of the Captex® 355 (oily internal phase of the emulsion) through long and short term stability assays. Based on the results, emulsions composed of Captex® 355, Tween 20® and Span 60® with 10.7 HLB were produced by three different methods: phase inversion, spontaneous emulsification and sonication. The results showed that the lowest diameter and best stability of the emulsions were achieved by the sonication method. The cationic emulsions were made by adding DOTAP to the basic emulsion. Its association with pIRES2-EGFP was evaluated by electrophoresis. Several rates of emulsion and DNA were evaluated and the results showed that 100% of the complex was formed when the rate DOTAP/DNA(nmol/µg) was 130. In conclusion, the overall results show the ability of the proposed emulsion to compact pIRES2-EGFP, which is a requirement to a successful transfection. Therefore, such formulation may be considered a promising candidate for gene therapy

Algoritmos de agrupamento aplicados a dados de expressão gênica de câncer: um estudo comparativo

The use of clustering methods for the discovery of cancer subtypes has drawn a great deal of attention in the scientific community. While bioinformaticians have proposed new clustering methods that take advantage of characteristics of the gene expression data, the medical community has a preference for using classic clustering methods. There have been no studies thus far performing a large-scale evaluation of different clustering methods in this context. This work presents the first large-scale analysis of seven different clustering methods and four proximity measures for the analysis of 35 cancer gene expression data sets. Results reveal that the finite mixture of Gaussians, followed closely by k-means, exhibited the best performance in terms of recovering the true structure of the data sets. These methods also exhibited, on average, the smallest difference between the actual number of classes in the data sets and the best number of clusters as indicated by our validation criteria. Furthermore, hierarchical methods, which have been widely used by the medical community, exhibited a poorer recovery performance than that of the other methods evaluated. Moreover, as a stable basis for the assessment and comparison of different clustering methods for cancer gene expression data, this study provides a common group of data sets (benchmark data sets) to be shared among researchers and used for comparisons with new methods

Comitês de grupamento aplicados a dados de expressão gênica

The main goal of this work is to investigate the suitability of applying cluster ensemble techniques (ensembles or committees) to gene expression data. More specifically, we will develop experiments with three diferent cluster ensembles methods, which have been used in many works in literature: coassociation matrix, relabeling and voting, and ensembles based on graph partitioning. The inputs for these methods will be the partitions generated by three clustering algorithms, representing diferent paradigms: kmeans, ExpectationMaximization (EM), and hierarchical method with average linkage. These algorithms have been widely applied to gene expression data. In general, the results obtained with our experiments indicate that the cluster ensemble methods present a better performance when compared to the individual techniques. This happens mainly for the heterogeneous ensembles, that is, ensembles built with base partitions generated with diferent clustering algorithms

Proteção constitucional do consumidor no âmbito da regulação publicitária

The concern with issues related to consumer protection has emerged in North America and then spread throughout the world. In Brazil, consumer‟s rights and interests only gained greater importance after their consolidation in the Constitution of 1988 and the enactment of the 8078/90 Law (Consumer‟s Protection and Defense Code), which established the consumerist microsystem. The understanding of the legal relationship of consumption concept is necessarily connected to knowledge of the elements that compose it. Among these, we can find the consumer and the provider (subjective elements), the product or service (objective elements), and the consumer‟s condition as final receiver of the consumption object (finalistic element). In order to elucidate the configuration of consumer protection before advertising communication, this work will analyze the advertising through the prism of consumerist laws, conceptualizing it and presenting a differentiation of it in relation to practices such as marketing, offer and commercial communication as well as examining its several kinds of manifestation, focusing mainly the ones categorized as misleading or unfair advertising. All kinds of advertising communication against the consumerist microsystem are subject to judicial control exercised by the State. Besides individual protection possibilities, this state-owned control can be collectively exercised as a result of the utilization of public civil action and popular action. Some specific categories of advertising (smoking products, alcoholic beverages, pesticides, medicines and therapies) are still subject to a set of particular restraints provided by the 9294/96 Law, which enables the performance of a special control in relation to them. In addition to state control, there is also a system of advertising communication self-regulation, which develops itself through the actions of the National Council of Advertising Self-Regulation that are based mainly on the laws established by the Brazilian Code of Advertising Self-Regulation and its annexes. However, this system of advertising self-regulation still has some deficiencies that hinder its effectiveness

Expressão gênica dos REα, REβ e PR em tumores mamários de cadelas por meio do q-PCR

A expressão de receptores de estrógeno (ER) e progesterona (PR) por meio da técnica de q-PCR foi avaliada em 26 cadelas portadoras de neoplasias mamárias e cinco cadelas sem afecções mamárias (grupo controle). Os resultados mostraram que os três grupos de animais estudados - com tumor maligno ou benigno e controle - expressaram receptores de estrógeno alfa, beta e progesterona. A quantificação relativa mostrou tendência para uma expressão maior de receptores no grupo controle e menor no grupo de animais com neoplasias malignas. Além disso, observou-se expressão maior de ERα em relação ao ERβ, e as neoplasias malignas de origem mista apresentaram maiores concentrações dos receptores PR, ERα e ERβ que as neoplasias de origem epitelial.

Influência de prolongados períodos de obesidade sobre a expressão gênica miocárdica

FUNDAMENTO: Vários autores mostraram que a deterioração da função cardíaca associa-se com o grau e a duração da obesidade. Os padrões de expressão gênica após longos períodos de obesidade precisam ser estabelecidos. OBJETIVO: Este estudo testou a hipótese de que a exposição prolongada à obesidade leva à redução nos níveis de RNAm de proteínas envolvidas na homeostase do Ca2+ miocárdico. Além disso, este estudo avaliou se uma diminuição no hormônio tireoidiano causava redução na expressão de RNAm. MÉTODOS: Ratos Wistar machos de 30 dias de idade foram distribuídos em dois grupos: controle (C) e obeso (Ob). O grupo C recebeu uma dieta padrão e o grupo Ob recebeu dietas hiperlipídicas por 15, 30 e 45 semanas. A obesidade foi definida pelo índice de adiposidade. A expressão gênica foi avaliada por PCR em tempo real quantitativa. RESULTADOS: O índice de adiposidade foi maior no grupo Ob do que no C em todas as etapas. Enquanto a obesidade nas semanas 15 e 45 determinou uma redução no RNAm de Ca2+-ATPase do retículo sarcoplasmático (SERCA2a), trocador Na+/Ca2+ (NCX) e calsequestrina (CSQ), observou-se aumento da expressão do RNAm de canal de Ca2+ do tipo L, receptor de rianodina, SERCA2a, fosfolamban (PLB), NCX e CSQ após a semana 30, em comparação ao grupo C. Não houve associação significativa entre os níveis de T3 e a expressão de RNAm. CONCLUSÕES: Nossos dados indicam que a obesidade por curtos ou longos períodos de tempo pode promover alteração na expressão gênica de proteínas reguladoras da homeostase do Ca2+ sem influência do hormônio tireoidiano
