Holt, Johnson and the 1966 Federal Election. A Question of Causality

US President Lyndon Johnson's state visit to Australia in October 1966, came at the pinnacle of support for Australia's military involvement in the Vietnam War. Johnson's visit also occurred just weeks before an election for the House of Representatives at which the ruling Liberal-Country Party Coalition won its eighth successive, and largest victory, The proximity of these events has led many to argue that a causal relationship exists between the two. Advocates of this thesis, however, have failed to support their position with any evidence other than the anecdotal. Contrary to the assertions made by numerous political historians and observers of the period, this paper finds no evidence to support a thesis of causality. This paper argues that the Coalition's landslide victory in 1966 was both a rejection of the tired and lacklustre leadership of Labor's Arthur Calwell and a measure of the electorate's overwhelming support for Holt and his Government's policies of conscription and military involvement in Vietnam.

The G-77, BASIC, and global climate governance: a new era in multilateral environmental negotiations

The G-77 has historically organized the participation of developing countries in multilateral environmental negotiations. This article analyses the impact of a new coalition of emerging powers - Brazil, China, India, and South Africa as BASIC - on the G-77's role in climate governance. While there are important benefits for both sides in their relationship, I argue that the G-77 is also disadvantaged in several concrete ways by the BASIC countries.

Political conditions for successful inflation stabilization: comparing Brazil and Argentina

This study tries to understand how Brazil and Argentina, two countries with chronically high inflation, achieved permanent stabilization by looking at political factors necessary for stabilization. It suggests that, although state autonomy or political unity may contribute to successful price stabilization, reconciling the interests of different stakeholders and thereby building a broad political support base is more essential for stabilization to succeed. Political skills of the leaders and compensatory policies may help raise such support and they are more crucial where other political conditions are less favorable. Also, rapid improvement in the economy is important for sustained political support, and thus, for successful stabilization.

Tribunal de Contas: defesa do dinheiro público também no caso-BES

Numa altura em que continuam em vigor uma série de misteriosos e injustos contratos de PPP’s, contratos futuros-swap e rendas artificiais outorgadas a lucrativos grupos económicos – e mais desfavoráveis às contas do Estado e contribuintes, como várias instituições e personalidades têm alertado em público incluindo a imprensa internacional -, a defesa dos dinheiros públicos assume cada vez maior importância. Abstract: At a time when still in force a series of mysterious and unjust PPP contracts, future swap contracts and artificial rents granted to profitable economic groups - and more unfavorable to the state and taxpayers of all, as several institutions and personalities have warned in public including the international press - the defense of public money is increasingly important.

A Política Científica e Tecnológica de Santa Catarina: análise a partir do modelo de coalizões de defesa

Este artigo utiliza o modelo de coalizões de defesa (Advocacy Coalition Framework - ACF), de Sabatier e Jenkins-Smith (1993), para analisar a prevalência da comunidade científica catarinense como ator-chave na formulação da Política Científica e Tecnológica (PCT) de Santa Catarina. A coleta de dados foi realizada a partir de relatórios e documentos oficiais das instituições, bem como de entrevistas realizadas com 10 atores do processo de formulação da PCT que ocuparam funções estratégicas no período de 1989 a 2009, assim classificados: 1) comunidade científica; 2) burocratas; 3) designados politicamente; 4) empresários; 5) políticos. A análise dos dados teve como conceitos sensíveis aqueles presentes no modelo de coalizões de defesa: a) o papel dos atores; b) sistemas de convicções e recursos; c) trajetórias da política pública; d) características da política pública; e) conteúdo da política pública. Foram identificadas as conexões entre os atores, suas convicções, estratégias, recursos e constrangimentos. A pesquisa conclui que a comunidade científica exerce um papel de destaque na formulação da política científica e tecnológica catarinense, sendo prevalente na formulação da PCT em todo o período analisado. Em relação aos empresários, políticos e burocratas, não se identificou uma atuação destacada e contínua desses atores. Entretanto, os designados politicamente, que na maioria das vezes são recrutados no seio da comunidade científica, exerceram papel importante na formulação e na reafirmação do sistema de convicções da comunidade científica. Em relação às principais trajetórias que ajudam a explicar as mudanças da PCT catarinense no período analisado, a trajetória "aprendizagem orientada pela política pública" destaca-se perante as demais.

Virtual power producers integration into MASCEM

All over the world Distributed Generation is seen as a valuable help to get cleaner and more efficient electricity. Under this context distributed generators, owned by different decentralized players can provide a significant amount of the electricity generation. To get negotiation power and advantages of scale economy, these players can be aggregated giving place to a new concept: the Virtual Power Producer. Virtual Power Producers are multi-technology and multi-site heterogeneous entities. Virtual Power Producers should adopt organization and management methodologies so that they can make Distributed Generation a really profitable activity, able to participate in the market. In this paper we address the integration of Virtual Power Producers into an electricity market simulator –MASCEM – as a coalition of distributed producers.

A multi-agent based approach for intelligent smart grid management

The spread and globalization of distributed generation (DG) in recent years has should highly influence the changes that occur in Electricity Markets (EMs). DG has brought a large number of new players to take action in the EMs, therefore increasing the complexity of these markets. Simulation based on multi-agent systems appears as a good way of analyzing players’ behavior and interactions, especially in a coalition perspective, and the effects these players have on the markets. MASCEM – Multi-Agent System for Competitive Electricity Markets was created to permit the study of the market operation with several different players and market mechanisms. MASGriP – Multi-Agent Smart Grid Platform is being developed to facilitate the simulation of micro grid (MG) and smart grid (SG) concepts with multiple different scenarios. This paper presents an intelligent management method for MG and SG. The simulation of different methods of control provides an advantage in comparing different possible approaches to respond to market events. Players utilize electric vehicles’ batteries and participate in Demand Response (DR) contracts, taking advantage on the best opportunities brought by the use of all resources, to improve their actions in response to MG and/or SG requests.

Virtual power producers market strategies

This paper presents MASCEM - a multi-agent based electricity market simulator. MASCEM uses game theory, machine learning techniques, scenario analysis and optimisation techniques to model market agents and to provide them with decision-support. This paper mainly focus on the MASCEM ability to provide the means to model and simulate Virtual Power Producers (VPP). VPPs are represented as a coalition of agents, with specific characteristics and goals. The paper detail some of the most important aspects considered in VPP formation and in the aggregation of new producers and includes a case study.

Renewable-based generation integration in electricity markets with virtual power producers

The development of renewable energy sources and Distributed Generation (DG) of electricity is of main importance in the way towards a sustainable development. However, the management, in large scale, of these technologies is complicated because of the intermittency of primary resources (wind, sunshine, etc.) and small scale of some plants. The aggregation of DG plants gives place to a new concept: the Virtual Power Producer (VPP). VPPs can reinforce the importance of these generation technologies making them valuable in electricity markets. VPPs can ensure a secure, environmentally friendly generation and optimal management of heat, electricity and cold as well as optimal operation and maintenance of electrical equipment, including the sale of electricity in the energy market. For attaining these goals, there are important issues to deal with, such as reserve management strategies, strategies for bids formulation, the producers’ remuneration, and the producers’ characterization for coalition formation. This chapter presents the most important concepts related with renewable-based generation integration in electricity markets, using VPP paradigm. The presented case studies make use of two main computer applications:ViProd and MASCEM. ViProd simulates VPP operation, including the management of plants in operation. MASCEM is a multi-agent based electricity market simulator that supports the inclusion of VPPs in the players set.

Transmission cost allocation using cooperative game theory: a comparative study

In this paper is presented a Game Theory based methodology to allocate transmission costs, considering cooperation and competition between producers. As original contribution, it finds the degree of participation on the additional costs according to the demand behavior. A comparative study was carried out between the obtained results using Nucleolus balance and Shapley Value, with other techniques such as Averages Allocation method and the Generalized Generation Distribution Factors method (GGDF). As example, a six nodes network was used for the simulations. The results demonstrate the ability to find adequate solutions on open access environment to the networks.
