O presente trabalho tem como objetivo identificar a forma como foi gerado o paradigma das políticas públicas sobre mudança climáticas no Brasil. Para alcançar este objetivo faz-se necessário um percurso analítico do que de mais relevante foi produzido nesse período, partindo da realidade Global em direção à realidade nacional. Considera-se que tais políticas públicas assentam-se em duas categorias básicas: globalização e governança. Os estudos sobre a globalização abordado neste trabalho, e sua dimensão ambiental, a partir do momento em que têm influenciado a agenda política dos Estados nacionais, resulta na contribuição da construção de uma governança contemporânea, especialmente o conceito de governança global climática, baseada na intersecção da governança global com as questões ambientais que dizem respeito aos efeitos negativos gerados pela mudança do clima. Entre as características dessa categoria estão a presença de novos atores, novos temas e nova correlação de forças, o que exige uma nova reorientação dos Estados nacionais, para o entendimento e o reconhecimento de novos padrões, inclusive os informais, não captados pelas instituições governamentais, ou seja, um sistema de governança exigido pela nova realidade impactada pela globalização, que apresenta desafios à ordem constituída, como a problemática das mudanças climáticas, evidenciado na instituição da Convenção Quadro sobre Mudança Climática e no Protocolo de Quioto das Nações Unidas. Finalizamos, mostrando como esse paradigma influenciou a construção das políticas nacionais e subnacionais sobre mudanças climáticas no Brasil.

ABSTRACT: To evaluate the short period climatic variations impact over Amazonic mangrove ecosystem, studies were carried out on the northeast coast of Para State. Sediments, surficial and interstitial waters were collected and examinated throughout salinity, pH and Eh (mV) measurements; mineralogical determination using X-ray diffraction and electronic microscopy. Chemical analysis of dissolved sulfides, sulfate and chloride, among others were made in samples collected seasonally, under spring and neap tides conditions. The seasonal chloride variations in the interstitial waters shows 20 g/l during the dry season and less of 10 g/l in the season; the concentration in surficial are higher at neap tides (rainy season) and spring tide (dry season). The dissolved sulfides were found only at 10 cm, indicating sediment exposure to the atmospheric oxygen advectives fluxes. The dissolved iron rates increases between 0-10 cm and the pH tends to neutrality. The saturation of interstitial waters at dry season is indicated by evaporitic minerals: gypsum and halite. The pluviometric variations are responsible by gradual changes in the nutrient and physical chemical properties of surficial and interstitial waters, into the saline equilibrium control at coastal waters, in the salinization and desalinization of sediments and the distribution of mangrove vegetation at the estuary. The prolonged exposure of sediments during the dry season and the morphological characteristics contribute to the total or partial oxidation of surficial sediments, modifying the mineralogy of sediments and the physical chemical characteristics of interstitial waters.

It is known that the urban environment modifies the energy balance between the surface and the atmosphere, causing changes in temperature, relative humidity, among other things, opening the way for studies aimed at urban climatology. Based on the theme of urban climate, this research focuses on the city of Assis, located west of São Paulo. The generation of urban climate is a result of various factors, among which stand out: the use and different land use, the thermodynamic properties of buildings, number of buildings in the urban, socioeconomic activities, etc.. In general, this increases the temperature and reducing relative humidity, providing thermal discomfort. The rural environment is used for comparison studies to this theme by presenting different characteristics in relation to the structure, morphology and urban functionality. The main objective of this study is to determine the characteristics of temperature and humidity environments with the habits and occupations of the different soils in winter, at night, one inserted into the urban fabric of Assis and the other in the rural environment, to verify for evidence of changes in climatic elements because of urbanization. To collect the data will be used mini automatic weather stations that record data on temperature and humidity. For analysis of the results will be made between the data obtained in the city and the countryside, developing graphics application using Excel to tabulate the data. It was found that there were differences in the thermo-hygrometric data collection points, showing a specific urban climate in the city of Assis

O processo de urbanização é bastante expressivo na modificação do clima na escala local, pois as formas materiais assumidas pela cidade, bem como as atividades que nela se desenvolvem, provocam anomalias nos elementos do clima como a temperatura, umidade relativa do ar, direção e velocidade do vento. Destes, a temperatura tem se destacado nos estudos sobre o clima urbano, pois as características da área urbana promovem seu aumento tanto no ar quanto nos alvos da superfície. Nesse sentido, este estudo objetivou detectar as anomalias térmicas intraurbanas e suas magnitudes, relacionando-as com os tipos de uso e ocupação da superfície do solo no município de Presidente Prudente-SP. Para tanto, foram realizadas análises das diferenças térmicas e higrométricas entre o urbano e o rural em dias representativos do inverno e do verão, e a verificação da temperatura da superfície através do sensoriamento remoto no infravermelho termal. Os resultados apresentaram que os tipos de tempo, assim como as características da superfície foram responsáveis pelas maiores ou menores diferenças entre a área urbana e a rural, o que demonstra a importância de se adequar o planejamento urbano às características do ambiente local

In 2010 two retailers signed an association agreement to gain an advantage in the market, however this association has promoted many changes within the companies. So this study had the objective to analyze the organizational climate, in the integration of companies context, in order to early detect deficiencies that could pose risks to the process of integration. The results collected from the questionnaires revealed the perceptions and expectations of employees regarding the integration of companies and their level of satisfaction with the organization, in addition, the data obtained from interviews allowed us to understand and to find some causes to the level of satisfaction presented by employees. The results made possible to identify strengths as the company‟s image, points of failure in communication and training and dissatisfaction with the workload, then some actions were suggested with the intention to achieve greater engagement and commitment of employees and consequently contribute to the success of the Integration Program. The conclusion of this study is that the changes promoted by the integration of companies impacted in the organizational climate and increased employees dissatisfaction

There are obvious changes that occur within the cities, experienced in synthesis for the degradation of the environment and especially the worsening quality of life. Even small cities, began to exhibit characteristics typical of an atmospheric climate. Thus, it becomes natural to analyze the characteristics of these spaces, unlike the medium and large cities, provide a detailed analysis of the peculiarities of intra-urban space in order to highlight what factors enhance or soften the formations of a typical urban climate distinct patterns of land use. The aim of this research from a geoenvironmental mapping of attributes (uses and land cover, vegetation and tree characteristics of buildings) while representing the dynamic City entertainment. Thus, we seek to inter-relate these indicators to analysis climate urban-rural and intra-urban applied to the city of Alfredo Marcondes / SP, a small town in order to identify a potential compromise climate conditions point to generate a specific climate. From this detailed analysis, we intend to give suggestions with the government to improve the comfort of that environment. For the data collection was organized a specific methodology for its collection, organization and representation and for the record of climatic data (temperature, wind speed and direction and cloud cover) were used mini-shelters weather with temperature sensors in fixed locations, and a temperature sensor attached on the side of a vehicle, 1.5 meters in height from the floor for 42 points perpassando selected in different intra-urban spaces...
