Guerra contra as drogas: uma análise sob a perspectiva do princípio da proporcionalidade

As substâncias entorpecentes acompanham a humanidade desde o início da civilização. No entanto, várias delas foram consideradas proscritas ao longo do tempo. Seu combate foi inaugurado na comunidade internacional a partir do começo do século XX. No início, tinha o condão eminentemente moral, porquanto a proibição encerrava, por princípio, a proteção da ética ameaçada pelo padrão desviado do consumo de estupefacientes. Na década de 1970, a guerra contra as drogas, expressão cunhada nesse período, evoluiu para se tornar o meio pelo qual o consumo seria mitigado. Dez anos mais tarde, ante à impossibilidade de sucumbir o narcotráfico, passou a ser um fim em si mesma o novo argumento para os esforços militares dos Estados Unidos da América. A criminalização das substâncias entorpecentes consideradas ilícitas é fundamento jurídico da guerra contra as drogas. Esse modelo proibicionista encontra argumento no direito penal do inimigo, segundo o qual o Estado pode, em situações que exponham a coletividade a grave perigo, negar à determinada categoria de criminosos (os inimigos) as garantias inerentes ao direito penal, cabendo-lhes apenas a coação estatal. Mesmo tendo consumido trilhões de dólares, encarcerado aos milhões e custado a vida de milhares de pessoas, pode-se dizer que a guerra contra as drogas não reduziu a oferta e o consumo de substâncias entorpecentes consideradas ilícitas, nem mitigou os danos delas decorrentes pelo contrário, tornou-se um problema de segurança pública. Assim, impõe-se a verificação da constitucionalidade da norma penal que fundamenta a guerra contra as drogas, sob ponderação do princípio da proporcionalidade. Referido postulado cobra que a norma seja adequada, cumprindo a finalidade pretendida, necessária, não havendo meio menos gravoso à obtenção do mesmo fim, e proporcional, estrito senso, que a sanção imposta ao indivíduo seja equivalente ao dano que se quis prevenir. Em matéria penal há de se incluir um outro elemento, a ponderar se as consequências da proibição em matéria penal, por si só, são mais graves que os consectários dos fatos que se pretendem proibir - exige-se que a lei seja socialmente menos ofensiva. A norma penal que fundamenta a guerra contra as drogas não se mostrou hábil a mitigar os danos sociais delas decorrentes sendo, por isso, inadequada. Existem meios alternativos à criminalização mais eficientes à esse objetivo, pelo que se faz desnecessária. Na medida em que estupefacientes mais nocivos à coletividade são considerados lícitos, a criminalização de drogas menos danosas se mostra desproporcional. E, uma vez que dela resultam graves danos à sociedade, não atende ao critério da menor ofensividade social. É, portanto, inconstitucional

Saída compulsória do estrangeiro do território nacional à luz dos direitos humanos: análise de casos

This paper aims to review traditional concepts inherent to the general theory of the state and human rights, relating to the legal situation of foreign, understood as the subject of rights, especially when the is case of compulsory legal imposition of exit from national territory. After the serious violations during the Second World War and the importance acquired by the International Law of Human Rights, values as dignity, justice and equality are enshrined in the legal system and its respect required beyond the boundaries of any country. The creation of an international community, which is governed by rules that its members are subordinated, without distinction, as well as state - based on volunteerism, become inspired by one principled nature of these new concepts required of Global Society, as well as the adoption, influenced by neoconstitutionalism, to the model of State Constitutional rule of law, are opposed to the idea of state sovereignty connected to a superiority, absolute and unlimited power which recognizes no other above it, not even the basic principles or axioms that must govern the relationships internally. So looks for a concept of state that includes all the requirements of a democratic society, that have the people as the power holder, understanding that state element has undergone a relativization, because had to adapt to the contemporary values applicable to the individual, inserting in its concept, the indispensable obligation to protect the inalienable rights of citizens, regardless of with whom he have legal and political bond of nationality. It happens that, to consecrate these privileges to individuals, which, because they contain reference to values with supranational characteristics, are very abstract and are in constant collision course with internal rules, making it difficult to reconcile, it will use hermeneutics of human rights, due mainly to international courts, correlated with constitutional exegesis, in particular, legal principiologia, using, among others, the principles of reasonableness and proportionality, the systematic interpretation of the Constitution and international legal standards. Thus, it seek to enshrine the common foundation of all law , the link between the systems, namely, the dignity of human beings. Finally, it will see if Brazilian jurisdiction, through case studies, is tuned in line with these new paradigms, and in line with the International Bill of Human Rights, the Federal Constitution, the values and principles she hired

Liberdade de expressão artística: concepções filosóficas, fundamentalidade constitucional e política da pluralidade

The right to artistic expression, freedom granted in the western democratic constitutionalism, is a fundamental right that cyclically, compared to other cohesive rights of expression, has been forgotten and put in an irrelevant juridical-dogmatic position. The first reason for this behaviour that disesteems artistic freedom is the valorisation of rationalism and scientificism in the modern society, subordinating academic researches to utilitarianism, relegating the purpose of feelings and spirituality on men s elocution, therefore, we investigate, guided by philosophy, the attribution of art on human formation, due to its capacity in harmonising reason and emotion. After that, we affirm the fundamental right to artistic expression s autonomy in the 1988 valid constitutional order, after a comparative explanation of freedom in the Fundamental Laws of United States, Portugal, Spain and Germany; and the construction historic-constitutional of the same right in the Brazilian Constitutions. In this desiderate, the theoric mark chosen is the Liberal Theory of the fundamental rights, guiding the exam through jusfundamental dimensions: juridical-subjective and juridical-objective. Whilst the first, classical function of resistance, delimitates the protection area of the artistic expression right from its specific content, titularity and its constitutional and subconstitutional limits, the other one establishes it as cultural good of the Social Order, defining to the State its rendering duties of protection, formation and cultural promotion. We do not admit artistic communication, granted without legal reserve, to be transposed of restrictions that belong to other fundamental rights and, when its exercise collides with another fundamental right or juridical-constitutional good, the justification to a possible state intervention that tangentiates its protection area goes, necessarily, through the perquisition of the artist s animus, the used method, the many viable interpretations and, at last, the correct application of the proportionality criteria. The cultural public politics analysis, nevertheless, observes the pluralism principle of democratic substratum, developer of the cultural dialogue and opposed to patterns determined by the mass cultural industry. All powers are attached, on the scope of its typical attributions, to materialise public politics that have the cultural artistic good as its aim, due to the constant rule contained in §1, art. 5º of the Federal Constitution. However, the access and the incentive laws to culture must be constantly supervised by the constitutional parameter of fundamental right to equality

Objetiva(ação) da medida e contagem do tempo em práticas socioculturais e educativas

This thesis describes and analyzes various processes established and practiced by both groups about the socio-cultural objective (action) the measurement and timing, mobilized some socio-historical practices as the use of the gnômon of the sundial and reading and interpretation of movements celestial constellations in cultural contexts such as indigenous communities and fishermen in the state of Pará, Brazil. The Purpose of the study was to describe and analyze the mobilization of such practices in the socio-historical development of matrices for teaching concepts and skills related to geometric angles, similar triangles, symmetry and proportionality in the training of mathematics teachers. The record of the entire history of investigation into the socio-historical practice, the formative action was based on epistemological assumptions of education ethnomathematics proposed by Vergani (2000, 2007) and Ubiratan D'Ambrosio (1986, 1993, 1996, 2001, 2004) and Alain Bishop conceptions about mathematics enculturation. At the end of the study I present my views on the practices of contributions called socio-cultural and historical for school mathematics, to give meaning to the concept formation and teaching of students, especially the implications of Education Ethnomatematics proposed by Vergani (2000) for training of future teachers of mathematics

Um algoritmo para estimação de estado em alimentadores de distribuição de energia elétrica com base no método da soma de potências

Most algorithms for state estimation based on the classical model are just adequate for use in transmission networks. Few algorithms were developed specifically for distribution systems, probably because of the little amount of data available in real time. Most overhead feeders possess just current and voltage measurements at the middle voltage bus-bar at the substation. In this way, classical algorithms are of difficult implementation, even considering off-line acquired data as pseudo-measurements. However, the necessity of automating the operation of distribution networks, mainly in regard to the selectivity of protection systems, as well to implement possibilities of load transfer maneuvers, is changing the network planning policy. In this way, some equipments incorporating telemetry and command modules have been installed in order to improve operational features, and so increasing the amount of measurement data available in real-time in the System Operation Center (SOC). This encourages the development of a state estimator model, involving real-time information and pseudo-measurements of loads, that are built from typical power factors and utilization factors (demand factors) of distribution transformers. This work reports about the development of a new state estimation method, specific for radial distribution systems. The main algorithm of the method is based on the power summation load flow. The estimation is carried out piecewise, section by section of the feeder, going from the substation to the terminal nodes. For each section, a measurement model is built, resulting in a nonlinear overdetermined equations set, whose solution is achieved by the Gaussian normal equation. The estimated variables of a section are used as pseudo-measurements for the next section. In general, a measurement set for a generic section consists of pseudo-measurements of power flows and nodal voltages obtained from the previous section or measurements in real-time, if they exist -, besides pseudomeasurements of injected powers for the power summations, whose functions are the load flow equations, assuming that the network can be represented by its single-phase equivalent. The great advantage of the algorithm is its simplicity and low computational effort. Moreover, the algorithm is very efficient, in regard to the accuracy of the estimated values. Besides the power summation state estimator, this work shows how other algorithms could be adapted to provide state estimation of middle voltage substations and networks, namely Schweppes method and an algorithm based on current proportionality, that is usually adopted for network planning tasks. Both estimators were implemented not only as alternatives for the proposed method, but also looking for getting results that give support for its validation. Once in most cases no power measurement is performed at beginning of the feeder and this is required for implementing the power summation estimations method, a new algorithm for estimating the network variables at the middle voltage bus-bar was also developed

Avaliação do processo industrial da cerâmica vermelha na região do Seridó - RN

Particularly in Braziland in Rio Grande do Norte, companies manufacturing red ceramic, play an important role as agents of development to study the region Seridó- RN, specific place for carrying out the research. It is observed in this region a concentration of red ceramic industries of small size, which, despite its importance in the ceramic, they are unable to enjoy or use the new forms of administrative management and technological advances designed and offered by universities, centers of research and projects of governments, remained almost entirely outside the progress and modernization, technological and administrative. These companies still have outdated technology, and management processes, providing quality problems and standardization of end products. Upon these conditions are the companies going through crisis and struggling to survive alone and without assistance. The region of Seridó-RN, lets make a detailed case study of red ceramic companies in the region proposed from the existing theoretical and actual lifting of the condition of the product manufacturing red ceramic, allowing through this overview of the implementation of collect samples of raw materials, allowing the study of each ceramic industry that contributed to the participation of the research, which was determined parameters such as: analysis of the physical, chemical and technological properties of raw materials, characterization of the processes used, raising the technological resources considering equipment, machinery, supplies, raw materials and facilities available and its organization by type of products from companies involved in this study. The methodology consists of the following steps: collection of raw material, crushing and screening, characterization of raw materials (liquid limit, chemical analysis, mineralogical analysis, differential thermal analysis, sieve analysis), mixing, forming, cutting, drying and burning of ceramic bodies and bodies of evidence. The results showed that it was clay with distinct characteristics with respect to plasticity. With respect to the different compositions of mixtures of ceramic masses, we conclude that the ceramic properties showed a direct proportionality with increasing fraction of the clay not plastic. However, the compositions of the masses studied proved to be the most appropriate for the types of simulated clay for use in ceramics. Adopted in the ceramic processing made it possible to obtain products the resulted in consistent properties, and in some cases even exceeding the requirements of technical studies and standard-Brazilian clays to obtain ceramic products such as tiles, bricks and tiles to floor. Based on the discussions from the results obtained in the various processing steps of this work, one can draw conclusions according to the physico-chemical and mineralogical properties of raw materials, the properties of ceramic products burned and analysis. This work may be used by other researchers, private companies and governmental organizations, undergraduate students and graduate, can develop studies and future research to: develop projects to modify the furnaces; mapping projects develop and rationalize the exploitation of raw materials ;promoting reforestation and forest management; develop reduction projects and recovery of waste; develop training projects in manpower sector, and develop security projects, improving the conditions of work in the area pottery

Análise comparativa das propriedades mecânicas do ligamento da patela e do tendão calcâneo

Com a finalidade de se comparar as propriedades mecânicas do ligamento da patela e do tendão calcâneo foram realizados ensaios de tração em material obtido de 25 cadáveres humanos. A idade dos doadores foi 58 ± 14 anos (33-85), sendo 19 (76%) masculinos e 6 (24%) femininos, 23 brancos (92%) e dois negros (8%). Os materiais foram testados em seus 10 mm centrais, com velocidade de aplicação de carga de 30 mm/min. Foi obtida a área de secção dos corpos de prova para que fossem estudadas as propriedades estruturais e materiais. Foram estudadas as seguintes variáveis: carga máxima (N), tensão(MPa), módulo de elasticidade (MPa), energia (Nm), alongamento absoluto (mm) e específico (%), limite de proporcionalidade (N), além da tensão (MPa) e alongamentos neste ponto. A análise estatística revelou que ambos possuem carga máxima, limite de proporcionalidade e tensão semelhantes (p>0,05). Nas outras variáveis ocorreu diferença significativa (p<0,05) com o tendão calcâneo apresentando valores maiores para energia e alongamento. O módulo de elasticidade, significativamente maior no ligamento da patela (p<0,05), foi a variável que melhor caracterizou a diferença do comportamento mecânico dos dois materiais.

Aplicação do Sensoriamento Remoto e do Sistema de Informações Geográficas na Detecção de Manchas de Óleo na Região do Pólo de Exploração de Guamaré, R.N.

Objective to establish a methodology for the oil spill monitoring on the sea surface, located at the Submerged Exploration Area of the Polo Region of Guamaré, in the State of Rio Grande do Norte, using orbital images of Synthetic Aperture Radar (SAR integrated with meteoceanographycs products. This methodology was applied in the following stages: (1) the creation of a base map of the Exploration Area; (2) the processing of NOAA/AVHRR and ERS-2 images for generation of meteoceanographycs products; (3) the processing of RADARSAT-1 images for monitoring of oil spills; (4) the integration of RADARSAT-1 images with NOAA/AVHRR and ERS-2 image products; and (5) the structuring of a data base. The Integration of RADARSAT-1 image of the Potiguar Basin of day 21.05.99 with the base map of the Exploration Area of the Polo Region of Guamaré for the identification of the probable sources of the oil spots, was used successfully in the detention of the probable spot of oil detected next to the exit to the submarine emissary in the Exploration Area of the Polo Region of Guamaré. To support the integration of RADARSAT-1 images with NOAA/AVHRR and ERS-2 image products, a methodology was developed for the classification of oil spills identified by RADARSAT-1 images. For this, the following algorithms of classification not supervised were tested: K-means, Fuzzy k-means and Isodata. These algorithms are part of the PCI Geomatics software, which was used for the filtering of RADARSAT-1 images. For validation of the results, the oil spills submitted to the unsupervised classification were compared to the results of the Semivariogram Textural Classifier (STC). The mentioned classifier was developed especially for oil spill classification purposes and requires PCI software for the whole processing of RADARSAT-1 images. After all, the results of the classifications were analyzed through Visual Analysis; Calculation of Proportionality of Largeness and Analysis Statistics. Amongst the three algorithms of classifications tested, it was noted that there were no significant alterations in relation to the spills classified with the STC, in all of the analyses taken into consideration. Therefore, considering all the procedures, it has been shown that the described methodology can be successfully applied using the unsupervised classifiers tested, resulting in a decrease of time in the identification and classification processing of oil spills, if compared with the utilization of the STC classifier
