DESEMPENHO DE ORGANIZAÇÃO SOCIAL (OS) NO GERENCIAMENTO DE ORGANISMOS PÚBLICOS: ESTUDO DESCRITIVO-EXPLORATÓRIO DO CENTRO NACIONAL DE PESQUISA EM ENERGIA E MATERIAIS - CNPEM

Este trabalho discutiu o desempenho do Centro Nacional de Pesquisa em Energia e Materiais CNPEM, que deu início às suas atividades como Associação Brasileira de Tecnologia de Luz Síncrotron - ABTLuS, Organização Social (OS), entidade da sociedade civil, sem fins lucrativos, disciplinada pela Lei 9.637 de 15 de maio de 1998, para gerir organismos públicos mediante a assinatura de contrato de gestão baseado em metas a serem cumpridas. O modelo nasceu concomitantemente com a criação do Ministério da Administração e Reforma do Estado MARE, na gestão do ministro Luiz Carlos Bresser Pereira, no governo do presidente Fernando Henrique Cardoso - FHC, tendo como princípio básico a prestação de serviços sociais, nas áreas de cultura, educação, pesquisa científica, proteção e preservação do meio ambiente e saúde, na expectativa de que ele pudesse prestar melhores serviços do que as empresas estatais e as entidades da administração direta. Hoje, dez anos se passaram e o CNPEM continua prestando serviços na área de pesquisa científica ao CNPq e ao MCT, apesar de não haver apoio para a criação de novas OS na esfera do governo federal, o que indicou ameaças ao seu ciclo de vida. A pesquisa desenvolveu-se através de estudo descritivo-exploratório, interpretando dados por intermédio do processo de hermenêutica para interpretação de dados retirados dos documentos institucionais, com conclusão favorável à continuidade do modelo, tendo em vista que a pesquisa demonstra que ele é legal, legítimo e competente no cumprimento das metas e missão, bem como está em plena forma física, sem ameaças ao seu ciclo de vida, demonstrando que tem muito a oferecer para a ciência brasileira e, como não poderia deixar de ser, a milhares de usuários espalhados pelo Brasil e o mundo.

Essays in Energy Economics

This thesis presents four essays in energy economics. The first essay investigates one of the workhorse models of resource economics, the Hotelling model of an inter-temporally optimizing resource extracting firm. The Hotelling model provides a convincing theory of fundamental concepts like resource scarcity, but very few empirical validations of the model have been conducted. This essay attempts to empirically validate the Hotelling model by first expanding it to include exploration activity and market power and then using a newly constructed data set for the uranium mining industry to test whether a major resource extracting mining firm in the industry is following the theory’s predictions. The results show that the theory is rejected in all considered settings. The second and third essays investigate the difference in market outcomes under spot-market based trade as compared to long-term contract based trade in oligopolistic markets with investments. The second essay investigates analytically the difference in market outcomes in an electricity market setting, showing that investments and consumer welfare may be higher under spot-market based trade than under long-term contracts. The third essay proposes techniques to solve large-scale models of this kind, empirically, by exploring the practicability of this approach in an application to the international metallurgical coal market. The final essay investigates the influence of policy uncertainty on investment decisions. With France debating the role of nuclear technology, this essay analyses how policy uncertainty regarding nuclear power in France may feature in the French and European power sector. Applying a stochastic model for the European power system, the analysis shows that the costs of uncertainty in this particular application are rather low compared to the overall costs of a nuclear phase-out.

A Logic Framework of Normative-based Contract Management

We explore of the feasibility of the computationally oriented institutional agency framework proposed by Governatori and Rotolo testing it against an industrial strength scenario. In particular we show how to encode in defeasible logic the dispute resolution policy described in Article 67 of FIDIC.

A trading strategy based on the lead–lag relationship between the spot index and futures contract for the FTSE 100

This paper examines the lead–lag relationship between the FTSE 100 index and index futures price employing a number of time series models. Using 10-min observations from June 1996–1997, it is found that lagged changes in the futures price can help to predict changes in the spot price. The best forecasting model is of the error correction type, allowing for the theoretical difference between spot and futures prices according to the cost of carry relationship. This predictive ability is in turn utilised to derive a trading strategy which is tested under real-world conditions to search for systematic profitable trading opportunities. It is revealed that although the model forecasts produce significantly higher returns than a passive benchmark, the model was unable to outperform the benchmark after allowing for transaction costs.

Towards a Monitoring Framework for Agent-Based Contract Systems

The behaviours of autonomous agents may deviate from those deemed to be for the good of the societal systems of which they are a part. Norms have therefore been proposed as a means to regulate agent behaviours in open and dynamic systems, and may be encoded in electronic contracts in order to specify the obliged, permitted and prohibited behaviours of agents that are signatories to such contracts. Enactment and management of electronic contracts thus enables the use of regulatory mechanisms to ensure that agent behaviours comply with the encoded norms. To facilitate such mechanisms requires monitoring in order to detect and explain violation of norms. In this paper we propose a framework for monitoring that is to be implemented and integrated into a suite of contract enactment and management tools. The framework adopts a non-intrusive approach to monitoring, whereby the states of a contract with respect to its contained norms can be inferred on the basis of messages exchanged. Specifically, the framework deploys agents that observe messages sent between contract signatories, where these messages correspond to agent behaviours and therefore indicate whether norms are, or are in danger of, being violated.

Projector-based augmented reality for intuitive intraoperative guidance in image-guided 3D interstitial brachytherapy

PURPOSE: The aim of this study is to implement augmented reality in real-time image-guided interstitial brachytherapy to allow an intuitive real-time intraoperative orientation. METHODS AND MATERIALS: The developed system consists of a common video projector, two high-resolution charge coupled device cameras, and an off-the-shelf notebook. The projector was used as a scanning device by projecting coded-light patterns to register the patient and superimpose the operating field with planning data and additional information in arbitrary colors. Subsequent movements of the nonfixed patient were detected by means of stereoscopically tracking passive markers attached to the patient. RESULTS: In a first clinical study, we evaluated the whole process chain from image acquisition to data projection and determined overall accuracy with 10 patients undergoing implantation. The described method enabled the surgeon to visualize planning data on top of any preoperatively segmented and triangulated surface (skin) with direct line of sight during the operation. Furthermore, the tracking system allowed dynamic adjustment of the data to the patient's current position and therefore eliminated the need for rigid fixation. Because of soft-part displacement, we obtained an average deviation of 1.1 mm by moving the patient, whereas changing the projector's position resulted in an average deviation of 0.9 mm. Mean deviation of all needles of an implant was 1.4 mm (range, 0.3-2.7 mm). CONCLUSIONS: The developed low-cost augmented-reality system proved to be accurate and feasible in interstitial brachytherapy. The system meets clinical demands and enables intuitive real-time intraoperative orientation and monitoring of needle implantation.

Feasibility of stereotactic MRI-based image guidance for the treatment of vascular malformations: a phantom study.

PURPOSE Treatment of vascular malformations requires the placement of a needle within vessels which may be as small as 1 mm, with the current state of the art relying exclusively on two-dimensional fluoroscopy images for guidance. We hypothesize that the combination of stereotactic image guidance with existing targeting methods will result in faster and more reproducible needle placements, as well as reduced radiationexposure, when compared to standard methods based on fluoroscopy alone. METHODS The proposed navigation approach was evaluated in a phantom experiment designed to allow direct comparison with the conventional method. An anatomical phantom of the left forearm was constructed, including an independent control mechanism to indicate the attainment of the target position. Three interventionalists (one inexperienced, two of them frequently practice the conventional fluoroscopic technique) performed 45 targeting attempts utilizing the combined and 45 targeting attempts utilizing the standard approaches. RESULTS In all 45 attempts, the users were able to reach the target when utilizing the combined approach. In two cases, targeting was stopped after 15 min without reaching the target when utilizing only the C-arm. The inexperienced user was faster when utilizing the combined approach and applied significantly less radiation than when utilizing the conventional approach. Conversely, both experienced users were faster when using the conventional approach, in one case significantly so, with no significant difference in radiation dose when compared to the combined approach. CONCLUSIONS This work presents an initial evaluation of a combined navigation fluoroscopy targeting technique in a phantom study. The results suggest that, especially for inexperienced interventionalists, navigation may help to reduce the time and the radiation dose. Future work will focus on the improvement and clinical evaluation of the proposed method.

Automatic generation of real-time deformable parametric model of the aorta for a VR-based catheterism guidance system

The purpose of this work is twofold: first, to develop a process to automatically create parametric models of the aorta that can adapt to any possible intraoperative deformation of the vessel. Second, it intends to provide the tools needed to perform this deformation in real time, by means of a non-rigid registration method. This dynamically deformable model will later be used in a VR-based surgery guidance system for aortic catheterism procedures, showing the vessel changes in real time.

Oil and Gas Environmental Documentation Guidance Based on Existing Environmental Assessment Documentation

The hard push for domestic oil and gas production suggests a developing divergence from environmentally sound practices. As states feel the pressure to match energy growth to national need, adequate consideration for the surrounding environment should continue to be a high priority. Through an analyses of twelve environmental assessment documents, recommendations for an oil and gas specific environmental assessment documentation guidance has been created. Guidance recommendations for the affected environment, mitigation options, alternatives, public comment process and the overall approach to an environmental assessment document is outlined within this capstone.

Behavior-Based Safety: Developing a Regional Guidance

A behavior-based safety program improves overall safety culture and safety performance of an organization. A solid behavior-based safety program is achieved by successfully implementing key components. Key components include management commitment to the process, an effective training program, a cohesive observation process and a successful data collecting and reporting system. This Applied Capstone project defines a regional approach for each of the key components of a behavior-based safety program. Recommendations resulting from the project provide the company studied guidance on developing a consistent behavior-based safety program.
