Turismo, território e políticas públicas: uma análise do destino João Pessoa/PB

This study presents an approach to tourism activity from the perspective of the territory, analyzing the importance of the roles of the State and public policies for tourism development. Tourism in the northeastern region of Brazil begins to take its rise from the late 1970 through public policies, whose goal was to provide the necessary conditions for tourism development. The tourism public policies were the key elements in the production process of tourist territories in the region. In the state of Paraíba, the public authorities elected the coastline as the main attraction and the state capital, João Pessoa, as the locus for the tourism development, with the city receiving a series of public policies. In this context, this research aims to analyze the development process of three specific public policies for tourism development in João Pessoa: The (mega)Projeto Costa do Sol (1988), the PRODETUR/PB I and II (1997 e 2005) and the Plano Estratégico de Desenvolvimento do Turismo na Paraíba, the Plano Amanhecer (2000). This study was guided by the question that even having been contemplated by the tourism public policies, João Pessoa still remains in a peripheral position in the regional tourism market. The methodological procedures for this study were literature and documents research and semi-structured interviews with tourism public officials and representatives from local tourism trade. The research came to prove that the discontinuity between governmental administrations hampered the implementation process of the tourism public policies studied. It was observed that the implementation of tourism public policies in the long term depends on the interaction between governments, as well as the collective political will to develop tourism in Joao Pessoa

Interpretação sísmica e análise de atributos - área do levantamento sísmico 3D de siririzinho (Bacia Sergipe-Alagoas, NE do Brasil)

The main objective of the present thesis was the seismic interpretation and seismic attribute analysis of the 3D seismic data from the Siririzinho high, located in the Sergipe Sub-basin (southern portion of Sergipe-Alagoas Basin). This study has enabled a better understanding of the stratigraphy and structure that the Siririzinho high experienced during its development. In a first analysis, we used two types of filters: the dip-steered median filter, was used to remove random noise and increase the lateral continuity of reflections, and fault-enhancement filter was applied to enhance the reflection discontinuities. After this filtering step similarity and curvature attributes were applied in order to identify and enhance the distribution of faults and fractures. The use of attributes and filtering greatly contributed to the identification and enhancement of continuity of faults. Besides the application of typical attributes (similarity and curvature) neural network and fingerprint techniques were also used, which generate meta-attributes, also aiming to highlight the faults; however, the results were not satisfactory. In a subsequent step, well log and seismic data analysis were performed, which allowed the understanding of the distribution and arrangement of sequences that occur in the Siririzinho high, as well as an understanding of how these units are affected by main structures in the region. The Siririzinho high comprises an elongated structure elongated in the NS direction, capped by four seismo-sequences (informally named, from bottom to top, the sequences I to IV, plus the top of the basement). It was possible to recognize the main NS-oriented faults, which especially affect the sequences I and II, and faults oriented NE-SW, that reach the younger sequences, III and IV. Finally, with the interpretation of seismic horizons corresponding to each of these sequences, it was possible to define a better understanding of geometry, deposition and structural relations in the area.
