In theory, shifts in institutional arrangements result in new public policies. This articles focuses on Curitiba, Brazil, an international flagship city of urban planning recognized for its technocratic government. The 2012 municipal elections and the 2013 nationwide political upheaval led to a change in the city's institutional arrangement. As a consequence, the 2014 Master Plan was conceived with the tagline of more public participation. This paper analyzes whether the changes in institutional arrangements influenced the city's planning process and the Master Plan.

The overall development of business operations logistics activities becomes more important for firms with the globalization of economy and therefore performance measurement being equally important. In order to break monopolistic control of Container Corporation of India (CONCOR), Indian Railways entered for competition in the container segment in January 2006 through private-public participation for customer centric competitiveness. The purpose of this book chapter is to benchmark the performance indicators in CONCOR. A case study has been conducted employing basic and super-efficiency models of Data Envelopment Analysis (DEA) on secondary data of CONCOR, Adani and Gateway container terminals from 1995-96 till 2010-11 for performance evaluation within CONCOR and comparative analysis for three organizations from 2005-06 till 2010-11. The exercise identified efficiency trends fluctuating between 87.5% to 1000% within CONCOR owing to haphazard infrastructure developed while comparison with private players showed 38.31% to 77.59% efficiency fluctuation concurrent to licensing policy norms.

Shale Formation

Refracturing technology has become an important means for the regeneration of old wells reconstruction. It is of great significance to understand the formation mechanism of hydraulic fracturing fracture for the design of hydraulic fracturing. In order to accurately evaluate and improve fracturing volume after refracturing, it is necessary to understand the mechanism of refracturing fracture in shale formation. In this paper, a true triaxial refracturing test method was established. A series of large-scale true triaxial fracturing experiments were carried out to characterize the refracturing fracture initiation and propagation. The results show that for shale reservoirs with weak bedding planes and natural fractures, hydraulic fracturing can not only form the main fracturing fracture, which is perpendicular to horizontal minimum principal stress, but it can also open weak bedding plane or natural fractures. The characteristics of fracturing pump curve indicated that the evolution of fracturing fractures, including initiation and propagation and communication of multiple fractures. The violent fluctuation of fracturing pump pressure curve indicates that the sample has undergone multiple fracturing fractures. The result of refracturing shows that initial fracturing fracture channels can be effectively closed by temporary plugging. The refracturing breakdown pressure is generally slightly higher than that of initial fracturing. After temporary plugging, under the influence of stress induced by the initial fracturing fracture, the propagation path of the refracturing fracture is deviated. When the new fracturing fracture communicates with the initial fracturing fracture, the original fracturing fracture can continue to expand and extend, increasing the range of the fracturing modifications. The refracturing test results was shown that for shale reservoir with simple initial fracturing fractures, the complexity fracturing fracture can be increased by refracturing after temporary plugging initial fractures. The effect of refracturing is not obvious for the reservoir with complex initial fracturing fractures. This research results can provide a reliable basis for optimizing refracturing design in shale gas reservoir.

Procedural Rights

In order to get the general public more involved in decisions regarding sustainable economic development, the Brazilian Congress approved a law specifically targeting availability and access to environmental information in 2003. This law was clearly inspired by the principles of 1998 Aarhus Convention which established the procedural rights to access to environmental information, public participation and access to court in environmental matters among European countries. This paper aims to compare the Aarhus Convention – with its innovative nature and open administrative and democratic practices – with applications on access to environmental information in Brazil. It first gives a brief explanation of the Aarhus Convention, followed by an overview of access to environmental information in Brazilian legislation and its recent evolution. The paper compares Brazilian legislation and the Aarhus Convention and identifies which criteria of the Aarhus Convention regarding access to environmental information have already been introduced in Brazilian legislation. In addition, the paper discusses the actual effectiveness of Brazilian Law 10.650/03 through an empirical exercise seeking to estimate how often it has been used to access environmental information.
