Constitucionalismo internacional: direitos humanos sob a ótica da globalização

The work presented here is the result of research on the issue of human rights in the face of conflicting issues such as the incorporation of international treaties, the sovereignty of states, globalization and multuculturalism. Specifically, we will investigate the origin of human rights, alongside his growing recognition, from the Revolutions until its completion in the Universal Declaration of Human Rights in 1948. The question, however, has become broader, when analyzed from the perspective of the internationalization of these rights as conditions and limits of democracy. Given the convergence on the reception of international treaties on human rights, we analyze a series of positions, including recent placements of the Supreme Court, and Constitutional Amendment n.45/2004. The study aims to review the classical concept of sovereignty, now within a new perspective based on the appearance of certain limitations of the state and a crisis in the face of the protection of human rights. We analyze the phenomenon of globalization in light of its complexity and its relation to sovereignty and human rights in pursuit of an expansion of democracy. The theme is consistent also with the line of contemporary constitutionalism, since their approach has a close connection with the issues of sovereignty and globalization, as well as a current relationship with the protection of human rights. The research aims to analyze the formation of a new society within a global vision of the constitutionalization of international law. It seeks to glimpse the invocacion model of foreign precedents and the possibility of dialogue betweem States as a way of protecting and enforcing the protection of human rights

Por uma pedagogia do oprimido midiático: meios de comunicação e suas intervenções na escola

En este trabajo nos ocupamos de la convergencia de la fotografía, el vídeo y la música, intermediado por una estación de radio en la escuela, instalada en la escuela Municipal de Djalma Maranhão, Natal, Rio Grande do Norte, en una clase de 5º año de jóvenes y adultos en el año escolar 2007. Se analizan las intervenciones causados los que participan en la vida escolar, a partir de las actividades realizadas por ellos, en la producción de programas de radio. Los procedimientos metodológicos sobre la base de la etnometodologia (COULON, 1995a, 1995b), en la investigación cualitativa (BOGDAN, BIKLEN, 1999, DENZIN y LINCOLN, 2006), participante como observador (MAY, 2004) y la investigación-acción (THIOLLENT, 1992). La comprensión de Paulo Freire en la comunicación e la educación es nuestro principal referente teórico. Los experimentos citados en los medios de comunicación revelaron varias posibilidades de mejora en la enseñanza y el aprendizaje, como el aumento de la autoestima de los estudiantes, social y de inclusión educativa de personas con discapacidad, disminución de la timidez y facilitar la comunicación entre los sujetos, lo que permite el diálogo entre ellos, intervino en sus relaciones sociales, más allá de los límites de la escuela. La investigación confirma, entonces, que la comunicación y la educación son parte de la misma naturaleza

A educação informal para o consumo infantil e juvenil na televisão e na mídia

The consumption has become a major pillar of modern capitalism and at the same time, one of the factors that relate to social inequality. Karl Marx developed the theory of historical materialism which maintains a history of society determined by class struggle and the! exploitation of man by man. Considered to be overtaken by those who believe that Marxism is synonymous with real socialism, the Marxist ideals seem more present than in the Western world which each individual takes the individualization (loss of sense of public and collective) and the alienation by the work. Weassumed we could work on these issues in student education, even in elementary school, through questioning of the consumer society, with the criticism of television and the media, the main promoter of the current sense of consumption, as an initial step that could lead to future autonomy of theindividual. The theory of ideology and ideas of Paulo Freire's liberating education theory permeated the experience that happened as a participant observation of groups in the discipline of sociology in the unit 2 of the Colégio Pedro II in Rio de Janeiro, the state capital, an institution under the direct administration Ministry of Education. Wehave found fertile ground in which the students were able to understand and question the meaning of advertising media

Métodos estatisticos em cadeias de Markov

Este trabalho tem como objetivo o estudo do comportamento assintótico da estatística de Pearson (1900), que é o aparato teórico do conhecido teste qui-quadrado ou teste x2 como também é usualmente denotado. Inicialmente estudamos o comportamento da distribuição da estatística qui-quadrado de Pearson (1900) numa amostra {X1, X2,...,Xn} quando n → ∞ e pi = pi0 , 8n. Em seguida detalhamos os argumentos usados em Billingley (1960), os quais demonstram a convergência em distribuição de uma estatística, semelhante a de Pearson, baseada em uma amostra de uma cadeia de Markov, estacionária, ergódica e com espaço de estados finitos S

Caracterização de processos morfodinâmicos e hidrodinâmicos do cinturão lacustre meridional da Reserva Biológica do Lago Pirituba, Amapá

The Amapá State has an important natural lake system, known as The Amapá Lakes Region . Most of these lakes are on the southern part of Amapá s coastal plain, which has 300 km of extension and it s composed by holocenic sediments deposited at the northern part of Amazon River to the Orange Cape located on the northern part of Amapá state. This region is under influence of the Amazon River discharge which is the largest liquid discharge of about 209.000 m³/s and biggest sediment budget discharged on the ocean in the order 6.108 ton per day. The climate is influenced by the Intertropical Convergence Zone and El Niño Southern Oscillation which act mainly under precipitation, nebulosity, local rivers and tidal hidrology. In this region lake belts are Ocidental, Oriental and Meridional Lake Belts. The last one is formed by the by the lakes Comprido de Cima, Botos, Bacia, Lodão, Ventos, Mutuco and Comprido de Baixo. These lakes are the closest to the Araguari River and are characterized by pelitic sedimentation associated with fluvial and estuarine flood plains under influence of tides. The lakes are interconnected, suffer influence of flood pulses from the Tartarugal, Tartarugalzinho and Araguari rivers and the hydrodynamic and morphodynamic know edge is poor. Volume and area reduction, natural eutrophication, anthophic influence, hidrodynamic alterations, morphological changes and are factors which can contribute to the closing of such lakes on the Meridional Lake Belt. This belt is inside the boundaries of the Biological Reserve of Piratuba Lake, created in 1980 for integral protection. Due to the fragility of the environment together with the poor knowledge of the system and with the study area relevancy it is necessary to know the hydrodynamic and geoenvironmental processes. This work aims the characterization of morphodynamic and hydrodynamic processes in order to understand the geoambiental context of the Meridional Lake Belt, from the Comprido de Baixo Lake to the dos Ventos Lake, including the Tabaco Igarape. Methodology was based on the hydrodynamic data acquisition: liquid discharge (acoustic method), tides, bathymetry and the interpretation of multitemporal remote sensing images, integrated in a Geographic Information System (GIS). By this method charts of the medium liquid discharges of Lake Mutuco and Tabacco Igarape the maximum velocity of flow were estimated in: 1.1 m/s, 1.6 m/s and 1.6 m/s (rainy season) and 0.6 m/s, 0.6 m/s and 0.7 m/s (dry period), the maximum flow in: 289 m³/s, 297 m³/s and 379 m³/s (rainy season) and 41 m³/s , 79 m³/s and 105 m³/s (dry period), respectively. From the interpretation of multitemporal satellite images, maps were developed together with the analysis of the lakes and Tobaco Igarape evolution from 1972 to 2008, and were classified according to the degree of balance in the area: stable areas, eutrophic areas, areas of gain, and eroded areas. Troughout analysis of the balance of areas, it was possible to quantify the volume of lake areas occupied by aquatic macrophytes. The study sought to understand the hydrodynamic and morphodynamic processes occurring in the region, contributing to the elucidation of the processes which cause and/or favor geoenvironmental changes in the region; all such information is fundamental to making the management of the area and further definition of parameters for environmental monitoring and contributing to the development of the management plan of the Biological Reserve of Lake Piratuba. The work activities is a part of the Project "Integration of Geological, geophysical and geochemical data to Paleogeographic rebuilding of Amazon Coast, from the Neogene to the Recent

Estudo comparativo de abordagens de inversão do fator de qualidade Q

Seismic wave dispersion and attenuation studies have become an important tool for lithology and fluid discrimination in hydrocarbon reservoirs. The processes associated to attenuation are complex and are encapsulated in a single quantitative description called quality factor (Q). The present dissertation has the objective of comparing different approaches of Q determination and is divided in two parts. Firstly, we made performance and robustness tests of three different approaches for Q determination in the frequency domain. They are: peak shift, centroid shift and spectral ratio. All these tests were performed in a three-layered model. In the suite of tests performed here, we varied the thickness, Q and inclination of the layers for propagation pulses with central frequency of 30, 40 and 60 Hz. We found that the centroid shift method is produces robust results for the entire suíte of tests. Secondly, we inverted for Q values using the peak and centroid shift methods using an sequential grid search algorithm. In this case, centroid shift method also produced more robust results than the peak shift method, despite being of slower convergence

O espaço central das atenções: o corredor de integração da região metropolitana de Natal

This work considers the space study of the main road runner of integration of the Region Metropolitan of Natal (RMN) in formation, emphasizing its repercussion for the geographic context of the city, where we identify the positive and negative aspects of such space configuration, as for the aspects of the urban inaquality, economic centrality and of flows, promoted for the state and private capital (national and foreign). The linear convergence and polinucleately of geographic objects in that we identify as Central Space of Attentions (CSA), promoted, and still it promotes, important repercussion in the space estructuretion of the peripheral areas of the RMN, such as in the constitution of the "Capital Value of the Space". In this direction, to endorse the analysis of such reading, choose as cientific ballast the geographic theory, in a perspective dialectic, as well as we rescue contributions of the science of the administration, sociology, economy, amongst others. From the empirical research, subsidized with the application of forms together the entrepreneurs whom they possess investments in the CSA, as well as in the rescue of information you register in cadastre in the Junta Comercial do Estado do Rio Grande do Norte (JUNCERN) and telephonic list, we construct a proposal of reading of the current period of training of the process of space production to which is rank the CSA. The analysis of the data, under a comparative space angle, presents an important contribution to reevaluate the urban space of the RMN in its bigger aspect, exceeding the limits of the studied road corridor

Monitoramento da qualidade das ásguas de chuvas conforme a atuação dos sistemas sinóticos na cidade de Natal/RN

Acid rain is a major assault on the environment, a consequence of burning fossil fuels and industrial pollutants the basis of sulfur dioxide released into the atmosphere. The objective of this research was to monitor and analyze changes in water quality of rain in the city of Natal, seeking to investigate the influence of quality on a local, regional and global, in addition to possible effects of this quality in the local landscape. Data collection was performed from December 2005 to December 2007. We used techniques of nefanálise in identifying systems sinóticos, field research in the search for possible effects of acid rain on the landscape, and collect and analyze data of precipitation and its degree of acidity. Used descriptive statistics (standard deviation and coefficient of variation) used to monitor the behavior of chemical precipitation, and monitoring of errors in measurements of pH, level of confidence, Normalized distribution of Gauss, confidence intervals, analysis of variance ANOVA were also used. Main results presented as a variation of pH between 5,021 and 6,836, with an average standard deviation of 5,958 and 0,402, showing that the average may represent the sample. Thus, we can infer that, according to the CONAMA Resolution 357 (the index for fresh water acidity should be between 6.0 and 9.0), the precipitation of Natal / RN is slightly acidic. It appears that the intertropical convergence zone figures showed the most acidic among the systems analyzed sinóticos, taking its average value of pH of 5,617, which means an acid value now, with a standard deviation of 0,235 and the coefficient of variation of 4,183% which shows that the average may represent the sample. Already in field research and found several places that suffer strongly the action of acid rain. However, the results are original and need further investigation, including the use of new methodologies

Ultrastructural aspects of the intercellular bridges between female bee germ cells

No ovário das abelhas as células germinativas e as células foliculares são interconectadas por pontes intercelulares mantidas abertas por reforços do citoesqueleto na membrana plasmática. As pontes entre as células germinativas têm comportamento dinâmico e provavelmente atuam na determinação do ovócito entre as células do clone formado pelas mitoses pré meióticas formando posteriormente uma via de transporte para que os produtos sintetizados pelas células nutridoras atinjam o ovócito durante sua maturação. Os elementos do citoesqueleto presentes nas pontes intercelulares das gônadas das abelhas são basicamente microfilamentos e microtúbulos, mas nas pontes entre os cistócitos pré-meióticos outro tipo de filamento (espesso de natureza não definida, associado a elementos do retículo endoplasmático) está presente, atravessando a ponte e prendendo-se através dos microfilamentos à membrana plasmática. Estes filamentos aparentemente controlam o vão da ponte. Terminada a fase de proliferação os cistócitos tomam a forma de uma roseta e um fusoma, formado pela convergência das pontes, aparece no centro desta. Nesta conformação os filamentos grossos não estão presentes. Nova mudança ocorre com a diferenciação do ovócito e das células nutridoras, com a reorientação de todas as pontes de maneira a canalizar o conteúdo das futuras células nutridoras para o ovócito.

Fato e ficção em Crônicas de fim do milênio, de Antonio Callado

Ao examinar os textos de Antonio Callado publicados na Folha de S. Paulo e reunidos no livro Crônicas de fim do milênio (1997), buscamos investigar de que maneira Callado lança mão de textos literários diversos para constituir seu ponto de vista nos comentários que faz sobre os dados do jornalismo e da história. Mais que uma ilustração do conteúdo das crônicas, essas obras apresentam-se como organizadoras de sua argumentação, revelando-se como um dispositivo de descoberta do mundo, por meio do qual o autor revê a história do Brasil. Nesse contexto, este trabalho aborda a trajetória da crônica brasileira e a obra geral de Antonio Callado, as quais apresentam um ponto fundamental de convergência com as crônicas do autor: a vinculação entre o texto literário, os fatos jornalísticos e os dados históricos, aspecto que se constitui como um dos eixos centrais de nosso estudo.

A aurora do (forte)piano

Este artigo revisita a aurora do fortepiano, instrumento que se tornaria ponto de convergência no fazer musical de fins do século XVIII até meados do XX, e apresenta referências documentais sobre o início da invenção da mecânica de Bartolomeo Cristofori, bem como documentações de outros projetos não Cristoforianos.

O expressionismo de Erwartung diante do problema do fetichismo musical

O monodrama Erwartung, de Arnold Schoenberg, foi caracterizado por um lado como síntese do expressionismo e, por outro, como uma composição não definível por meio de categorias formais. Esta convergência entre expressão e negação da forma, apontada por Carl Dahlhaus, é o ponto de partida deste texto, cujo objetivo é sustentar, mais do que uma simples convergência, uma relação determinada entre expressão e negação da forma, ou da convenção. Isto é realizado em três momentos: primeiro, desenvolve-se o conceito adorniano de fetichismo musical; segundo, aborda-se a relação entre a expressão e a convenção à luz do problema do fetichismo musical, o que permite aproximar noções como a negação da convenção, a negação romântica do objetivismo musical em prol da expressão subjetiva e a recusa de materiais fetichizados; em terceiro lugar, aborda-se Erwartung, mostrando como o problema da convenção, do objetivismo e do fetichismo não deixam de aparecer em uma peça que leva às últimas consequências a radicalização da expressão pela negação da convenção.
