Potencialidades de cultivo de macroalgas no litoral do Rio Grande do Norte (NE, Brasil): uma perspectiva de integração de dados ambientais em sistemas de informação geográfica (SIG)

Since centuries ago, the Asians use seaweed as an important source of feeding and are their greatest world-wide consumers. The migration of these peoples for other countries, made the demand for seaweed to increase. This increasing demand prompted an industry with annual values of around US$ 6 billion. The algal biomass used for the industry is collected in natural reservoirs or cultivated. The market necessity for products of the seaweed base promotes an unsustainable exploration of the natural banks, compromising its associated biological balance. In this context, seaweed culture appears as a viable alternative to prevent the depletion of these natural supplies. Geographic Information Systems (GIS) provide space and produce information that can facilitate the evaluation of important physical and socio-economic characteristics for the planning of seaweed culture. This objective of this study is to identify potential coastal areas for seaweed culture in the state of Rio Grande do Norte, from the integration of social-environmental data in the SIG. In order to achieve this objective, a geo-referred database composed of geographical maps, nautical maps and orbital digital images was assembled; and a bank of attributes including physical and oceanographical variables (winds, chains, bathymetry, operational distance from the culture) and social and environmental factors (main income, experience with seaweed harvesting, demographic density, proximity of the sheltered coast and distance of the banks) was produced. In the modeling of the data, the integration of the space database with the bank of attributes for the attainment of the map of potentiality of seaweed culture was carried out. Of a total of 2,011 ha analyzed by the GIS for the culture of seaweed, around 34% or 682 ha were indicated as high potential, 55% or 1,101 ha as medium potential, and 11% or 228 ha as low potential. The good indices of potentiality obtained in the localities studied demonstrate that there are adequate conditions for the installation of seaweed culture in the state of Rio Grande do Norte

Parallel Cyclostationarity-Exploiting Algorithm for Energy-Efficient Spectrum Sensing

The evolution of wireless communication systems leads to Dynamic Spectrum Allocation for Cognitive Radio, which requires reliable spectrum sensing techniques. Among the spectrum sensing methods proposed in the literature, those that exploit cyclostationary characteristics of radio signals are particularly suitable for communication environments with low signal-to-noise ratios, or with non-stationary noise. However, such methods have high computational complexity that directly raises the power consumption of devices which often have very stringent low-power requirements. We propose a strategy for cyclostationary spectrum sensing with reduced energy consumption. This strategy is based on the principle that p processors working at slower frequencies consume less power than a single processor for the same execution time. We devise a strict relation between the energy savings and common parallel system metrics. The results of simulations show that our strategy promises very significant savings in actual devices.

Programa de aquisição de alimentos (2003-2010): avaliação da implementação pela CONAB no Rio Grande do Norte

This thesis aimed to evaluate the implementation of the Food Acquisition Program(PAA) through CONAB RN in the period of 2003-2010 with the perception of all agents involved in the implementation of the government program.For the methodological trajectory it was adopted a descriptive bibliographical and documentary approach with triangular qualitative and quantitative, also called evaluative research.The theoretical model was supported by the authors Draibe (2001), Aguilar and Ander-Egg (1994) and Silva(2001), among others, that focused on family farming and evaluation of implementation of public policy having as a category of analysis the size implementation of policy and the latter divided into 10 theoretical dimensions.The universe consisted of three groups: the first were the managers and technicians from CONAB(RN and Brasilia), totaling 15 subjects. The second group was of associations/cooperatives that participated in the programin 2010, totaling a sample in each access of 15 representatives. The third group of subjects totaled with 309 representatives of governmental and non-governmental organizations that received donations of food for the same period. Semi-structured interviews and forms were adopted as instruments of data collection.The data were processed qualitatively by the analysis of content (interviews and documents) and quantitatively by means of statistical tests that allowed inferences and adoption of frequencies. Among the key find ingests that the program is not standing as a structure supported by planning. The interests of the performers do not necessarily converge with the objectives of the Food Acquisition Program (PAA). A shockof goals was identified (within the same program) when comparingthe financial agent (Ministry of Rural Development and of Social Development and Fight Against Hunger Ministry r) and the executor, CONAB/RN. Within the assessed dimensions, the most fragileis the sub-managerial decision-making and Organizational Environment and internal assessment, still deserves attention the sizeof logistical and operational Subsystem, as this also proved weak.The focusin the quest toexpand thequantificationof the resultsof theFood Acquisition Program (PAA)by CONAB/RN does forget a quality management focused on what really should be:the compliance with the institutional objectives of the government program.Finally, the perspective for the traded implementation should be re-examined because excessive discretion by managers along with technical staff has characterized there al role of the Food Acquisition Program (PAA) as public policy. We conclude that the implementation model, which apparently aggregates values to the benefitted citizens, has weakened the context of work on family farms having the management model of the implementation process be reviewed by the Federal Government and point too ther paths, which have as a guide line the emancipation and developmentof the field or in the field andat the same time enables the reduction of nutritional deficiency of beneficiaries in a balanced and coherent way

Gestão democrática nas escolas: a atuação dos diretores escolares e os desafios para sua consolidação na rede municipal de Natal/RN

The democratic management is a challenge for education, on the one hand for its actualization needs a link between the government and the educational institution. From that, research aims to understand the main challenges faced by the school administration to consolidate the management of public schools in Natal/RN. Against this context the methodology used was multiple cases, qualitative approach in which respondent were manager (director, deputy director and coordinator) of the four municipal schools and two representatives of the Democratic Management Commission of a Government departament of Education, Natal/RN. The analysis was made by peers, between schools that had grade superior IDEB that average stipulated by the federal government and two that had grade lower and between managers and representatives of the Secretary. Were used techniques of categorization and content analysis of the speeches of respondents. Was note that managers understand the importance of the participation about whole community in the democratic management, however only one school highlighted means of attracting the parents against to the difficulty of representing these. The lack of knowledge about the democratic management is evident mainly in the pair of schools with lower IDEB. That schools with a lower IDEB adhere to this management as a way to meet rules. So unanimous, the broad role of director hampers knowledge about the legislation. About relationship of the Government department with managers, there are some contradictions between the understanding of the role of the coordinator by managers and representatives of the Government department. It was perceptible the no uniformity about a good relationship between managers and Government department. It was notable features of democratic management in all school units, well as the efforts of the Government department in this scope. However there are also undemocratic features that deserve further study

A previdência rural universalista e a sua relevância na economia dos municípios do Rio Grande do Norte

This study deals with the rural social security Universalist established by the Constitution of 1988 and its importance in the economy of the municipalities of Rio Grande do Norte. In this context, the study seeks to satisfy two important criteria that guide the selection of objects of social science research: a consideration of issues that have relevance to the real world and the intention to make the contribution to the scholarly literature on theoretical and empirical aspects. The research seeks to reveal what is the economic importance of the subsystem of social security for rural municipalities in RN. The hypothesis is that the transfer of income received by beneficiaries from the rural social security tax exceeds the explicit mechanisms for most municipalities in RN, in many cases significantly, proving the importance of this policy as a mechanism for combating poverty and reducing social inequality, especially before the fragility of the federal system on the national political entity hall. The study presents theoretical cores - chapters 1-3 - and empirical - Chapter 4. The first core is about the evolution of social protection as a state policy, addressing the influential theories and typologies of the State of Social Welfare and the characteristics of the Brazilian social security model, but mainly, its rural social security subsystem, its history until universalistic model inaugurated by the Federal Constitution of 1988. The second begins with an overview of studies that have emphasized the impact of Social Security on the local economy of small municipalities, then passing data and statistics in order to gauge the socioeconomic importance of pension income in the rural municipalities of Rio Grande do Norte. To this end, the final chapter provides a comparison of the monetary value transferred by the payment of social security benefits - rural and urban - to each of the 167 municipalities in RN with the equally important sources of income in the budget of municipal entities. Apart from their own tax revenues, are objects of comparison with the value of pension benefits awarded in RN, transfer quota state relating to the municipality on the federal ICMS and the transfer on the FPM

Estrutura econômica, mercado de trabalho e evolução sócio-ocupacional no Rio Grande do Norte 2001 a 2008: reflexo de uma condição mercantil e estruturalmente periférica

The aim of this thesis was to investigate the evolution of the socio-occupational status in Rio Grande do Norte from 2001 to 2008, based on the characterization of the socio-economic status of this State from the analysis of labor market norte-rio-grandense . The study, specifically, drew a comparison between the dynamics of the labor market in Rio Grande do Norte and the capital city, Natal. From this perspective, the purpose was to make a relationship between the social division of labor and its effects on the socio-spatial division, represented in the "macro scale" by the federal unit and the "micro level" for the capital; locus of economic and population concentration. The collection of data on the labor market had as a major source PNAD/IBGE, characterizing the labor market in many ways: people of working age, economically active population and employed and unemployed people, classified by age, sex, color, education, income and social protection condition. However, as for the socio-occupational division, we follow the methodology used by the research group on national television, based in IPPUR /UFRJ, called Monitoring of the Metropolis," which rallied twenty-four groups that aggregate the occupations found in the PNAD/IBGE, in eight groups of socio-occupational categories, according to the similarity between them. It was used in the socio-spatial cutting two relevant discussions, which are inter-related and were characterized as crucial points in developing the research problem: the former was related to the influence of the hegemony of merchant capital in the labor market in Rio Grande North and, the latter, it referred the socio-economic relations between the territory and the variable occupation. Lastly, the results all indicated that in Rio Grande do Norte, as a peripheral state, has suffered the devastating influence of the hegemony of capital purely commercial basis, where "wealth" of capitalism is generated through the sphere of mere movement of goods and services rather than a productive process due to the social relations of production more advanced. We have a little advanced economic structure, with a tertiary sector that has propagated under-employment or disguised unemployment. Similarly, the agricultural sector has been presented as an example of greater social degradation of working conditions in the state. The secondary sector, in turn, also was not behind this uncertainty; on the contrary, confirmed that condition, with poor levels of income, low education of the workforce and a high degree of social helplessness, even in the state capital, space full urban area, which although always appear with a favorable condition compared to Province, in practically most of the variables studied, was also reflected at the same time the author of a structurally underdeveloped condition

O direito social fundamental de acesso à energia elétrica e a atuação estatal

Electrical energy today is an essential element in the life of any human being. Through the access to electrical energy it is possible to enjoy dignified conditions of life, having in mind the possibility of making use of minimal material conditions of life. The lack of access to electricity is directly linked to poverty and degrading conditions of life, in which are some communities in Brazil, especially the more isolated from urban centers. Access to the electric service is a determining factor for the preservation of human dignity, constitutional principle inscribe in the art.1 of the Federal Constitution, and the promotion of development, being a right of everyone and a duty of the State to promote universal access. For that reason, focuses mainly on the analysis of their setting as a fundamental social right and its importance for national development. For this, the theoretical and descriptive method was used, with normative and literary analysis, in particular the Constitution of 1988. This study also discusses the form of action of the State in the energy sector, to give effect to the fundamental social right of access to electricity, the characteristics of public service and the principles that guide it, in addition to the role of public policies in universalization of access, in particular the analysis of the Program Luz para Todos, and the function of regulation in the implementation of these policies and the provision of adequate public services.

Licenciamento ambiental em postos de revenda de combustíveis à luz dos princípios constitucionais de defesas do meio ambiente: o caso do município de Natal/RN

This study approaches the question of the administrative procedure of the environmental licensing of ranks of fuel resale, taking as basis a study case of the reality of the City of Natal/RN (Brazil). For in such a way, it was done a retrospect on the evolution of the system of road transport in Brazil, having started to briefly analyze the urbanization process that if after accented in the capitals of the Brazilian States the decade of 1950, relating these subjects with the growth of the sector of fuel resale. After that, it was transferred boarding of the defense of the national environment to the light of ambient principles constitutional. In the sequence, a boarding on the ambient guardianship in the Federal Constitution of 1988 was made, treating basically specifies and on the national urban politics and the national politics of the environment, with its instruments. In the sequence, it was transferred the analysis of the abilities and attributions of the National Advice of the Environment (CONAMA) and its Resolutions, for then only enter in the most important part of this work: an analysis of the environmental licensing of ranks of fuel resale, in the reality of the City of Natal/RN. Before this specific boarding, it was proceeded specifically a survey and communication from the applicable norms to such establishments (Resolutions of the CONAMA and norms of the ABNT), for after that carrying through an geo-ambient characterization of the City of Natal/RN. Finally, a reflection was made on the possibility of magnifying of the state activity, in terms of guarantees for the responsible members for the environmental policy and of administrative efficiency, through the idea of the ambient regulation. For the accomplishment of this study, it was proceeded research in diverse sources such as books, magazines, sites of the Internet, periodicals, thesis and dissertations, among others material, beyond visits the agencies that direct or indirectly act with the ambient defense and as fuel resale, such as Secretariat of Environment and Urbanism of the City of Natal (SEMURB), Institute of Economic Development and Environment of RN (IDEMA), Brazilian Institute of the Environment and the Natural resources You renewed, Executive Management of RN (IBAMA/RN), Public prosecutor's office of the Environment of Natal (Public prosecution service of the RN), National Agency of Oil (ANP) and Union of the Retailing of Derivatives of Oil of the RN, among others. To the end, satiated regulation is observed that although on the substance of the ambient licensing in ranks of fuel resale, also with federal, state and municipal norms, the municipal Public Power is very far from the fulfilment of its institutional functions, in the question environmental policy of these establishments, a time that few are the permitted ranks of resale in the city of Natal/RN

O município brasileiro e o direito fundamental do acesso à justiça: a prestação da assistência jurídica municipal ao necessitado

This scholarly work aims to investigate the feasibility and constitutionality of access to justice through the provision of full and free legal assistance by the Brazilian municipalities. Investigates the historical aspects of federalism in a global context, emphasizing the contributions left by American federalism. In the Brazilian context, emphasizing the importance of municipalities as federal entities and their outstanding characteristics, while addressing regional issues of federalism. Leanings to the more detailed analysis of the Brazilian municipalities, contextualizing its legal status, its independence and its constitutional powers. It is emphasized in the same way, the relevant transformations of Brazilian municipalities over the last twenty years of this Constitution of the Federative Republic of Brazil in 1988, especially the various constitutional amendments that affected the local autonomy and budgetary aspects, fiscal and skills, bringing significant changes to the municipalities. It is an approach to the concept of justice and deepening the studies on the fundamental right of access to justice in its various connotations. In this vein, it is a study on the legal advice provided in Brazil, especially the powers of the Public Defender of the States and Union, as well as the provision of such public service by Brazilian municipalities and its relevance to citizens in need.

At this point the thesis, one wonders if some important aspects of this activity such as political influence and patronage, very common in day-to-day municipal prosecutors and legal advisers, public employees or occupying commissioned positions within the municipal administrative structure in several municipalities throughout Brazil. Finally, there will be a conclusion as to the constitutionality of the service being done by presenting proposals and recommendations that may improve the municipal legal aid, allowing a constitutional backing to this important service is being provided in capital cities and municipalities throughout the length of Brazil

Federealismo e desenvolvimento: cooperação entre os entes federados limites, direitos e deveres

Taking as a starting point the Classic Federalism and theory of the development this Work intend to present some ideas linked about cooperation between federal entities and intergovernmental relations with the main focus the regulation by the Public Consortia aimed at administrative efficiency as a Constitutional Principle of Activity Administrative, against the current provisions of the Federal Constituition of 1988, and infraconstitutional legislation in order to provoke debate and criticism about the principle of cooperation adopted as a paradigm and the capabilities that the state has and what it is, in fact, an efficient management public. It is in the growth of the state, and not a decrease as a minimal state, which aims to discuss its role in promoting the collective interests, and it is therefore essential, as an institution able to intervene on citizens in the search for socially relevant results. Study Federalism and Development on the premise of public consortia and administrative efficiency requires study the course of history as the formation of the Brazilian State, in particular the fact that he is in joint effort between federal agencies - federal, state and municipal - in order to better review the relations established in this plan, in what concerns directly on the issue of division of powers, especially the common or competitors and the subject of the highest relevance for the implementation of an effective federal pact. Finally, the objective of this Work is not only particularize the institute of public consortia, it is intended to demonstrate the deviousness of the concept of efficiency and the division of powers of federal agencies and the constitutional contribution of the institute as a program that should be put in a tone of debate, adequacy of the practice and the law itself

A Constitucionalidade do decreto de licitações da Petrobrás à luz dos princípios da legalidade e da eficiência

PETROBRAS, a Brazilian oil company, follows principles of public administration and from the Constitutional Amendment 9/95 in Brazil began to compete with other companies with the flexibility of the oil monopoly. In this new model started to use the simplified procedure for bidding so that could compete on equal terms. The ordinance that adopted a simplified procedure for bidding has been the subject of some criticism and lawsuits especially under the Court of Audit and the Supreme Court in Brazil. The analysis of their constitutionality, and the possibility of their use by other group companies is the theme of this work, and for this purpose, permeates through the notions of judicial review in the Brazilian law on the stage of law and economics analysis of the norm, and the principles applicable to PETROBRAS and the devices most frequently asked about the implementation of 2745/98 Decree. For this, the basic issue that should be investigated further is the regulatory power of the Federal Executive and the delegation of powers within the legislature and its conformation to the constitutional regency

Fiscalização difusa da constitucionalidade e o incidente de argüição de inconstitucionalidade

The present work consists of studying to diffuse control of constitutionality in Brazil, with emphasis in a procedural alternative to the evolution of that model: the incident to challenge of unconstitutionality. Starting from the discussion about the new role of constitutional jurisdiction in peripheral countries and in the globalized society, without forgetting to face inevitable doubts about its legitimacy before other powers of the State, the Brazilian control of constitutionality is revealed, under a diffuse, non-dichotomical view, through a number of inconsistencies and misunderstandings, that compromise social peace, the credibility of democratic institutions and the supremacy of juridical security. In order to achieve the goal, the study in course discussed the main difficulties of the Brazilian mixed model of constitutionality control, as well as, directing its view to the incident of challenge of unconstitutionality, which the most adequate forms to assure its appropriateness, legitimacy, processing and decisory effects are. Is was essential, in this point of view, to establish the difference between the incident of challenge of unconstitutionality conceived in article of the Brazilian Federal Constitution and the incident of challenge of unconstitutionality such as it is known in the European models. The insertion of the incident of challenge of unconstitutionality based on European models in the Brazilian control system, without jeopardizing the North-American essence the Brazilian constitutional history presents since 1981, is the hypothesis that is presented as an improvement of constitutional protection

Diagnóstico e avaliação das áreas de destino final dos resíduos sólidos urbanos no estado do rio grande do norte

This work aims to present the diagnosis and the evaluation of areas of final destination of urban solid waste in Rio Grande do Norte (RN) state. The survey was based on the experience of the State of São Paulo, which made its first inventory in 1997, through its Companhia de Tecnologia de Saneamento Ambiental CETESB. The methodology for the structuring of diagnosis was the Índice de Qualidade de Aterros de Resíduo -- IQR, developed by the Institute for Technological Research of São Paulo (ITRP). The calculation is based on the completion of a matrix that contains information about the main features of the site, infrastructure and operating conditions of the area of waste disposal. This study intends to subsidize the state government of Rio Grande do Norte through its State Secretariat of Environment and Water Resources and the Instituto de Desenvolvimento Sustentável e Meio Ambiente do RN (IDEMA), as well as federal, state and municipal authorities, in the definition of public policies for integrated management of municipal solid wastes to take account of environmental preservation and improvement of sanitary conditions of Natal-RN population.

Passivo ambiental e o setor de exploração de petróleo em terra: abordagem teórica e percepção institucional dos impactos ambientais gerados na atividade

The search for a sustainable development is result of the exhaustion of the natural resources of the planet that demands globalizated politics with practical of compatible economic development with the protection of the quality of life for the future generations. This work presents a study on the thematic on the environmental liabilities in the organizations with focus in the industry of the oil and the production of oil in land in the state of Rio Grande do Norte. Some types of environmental liabilities are presented, as well as, some estimates techniques. Moreover, this work presents surveys of some variable that stimulate the organizations to implant technologies of reduction of the impacts in the environment as: the environmental legislation, costs, the main impacts of the production of oil in land. On the basis of the bibliographical research and in the identified variable, it was carried a case study with state and municipal technician that act in the sectors of fiscalization (IBAMA-RN and IDEMA-RN) with the objective to deepen the discussion regarding the impacts of the industry of the oil, the effectiveness of the current law, the performance of the institutions the federal level and how to prevent impacts in the environment. It was observed that the environmental liabilities are a little spread subject in the organizations, perhaps to be unknown and of few theoretical referencees at the national level, regarding to the evaluation techniques. At the same time, absentee in the national politics that conducts the oil exploration

O (in)imaginável elefante mal-ajambrado: a questão de limites entre o Ceará e o Rio Grande do Norte e o exame da formação espacial e identitária norte-rio-grandense na Primeira República

This study s main goal is to analyze the way the limits between Ceará and Rio Grande do Norte states, the so called Grossos matter, has been associated to the norte-rio-grandense spacial and identity formation during the first republic period. Thus, a consistet number of sources: RN and CE old newspapers, as well as a república from Natal and Fortaleza and o mossoroense ; historical drafts from the historical and geographical institute associated and historical, gographical and anthropological institute of Ceará; the Ação Cível Originária de nº 6 from the supreme federal tribunal and many other cartographies. The documents haven t been hierarchized, neither accepted as proof effects, but understood as the base matter for this text composition by the deconstruction of the analyzed discusses. In order to do that the ablação or bricolagem method, without quotations marks or long quotations themselves, has been used. Along the three analyzed charpters: the two phases the litigious was found, since its beginning yet in the XVIII century until 1888 and its return within the republic proclamation, in the 1920 resolution; the development of the documental, historical and identity dispute between IHGA-CE and IHG-RN; and, at last, the political game existing between the Albuquerque Maranhão oligarchy , Manuel Pereira Reis and Rui Barbosa, explaining the intentions, silent and miths built along the time by these intellectual participations
