March 2018 Copyright © 2018 Stellenbosch University All rights reserved i Stellenbosch University https://scholar.sun.ac.za ABSTRACT While most international political economy (IPE) literature has been concerned with the relations between multinational corporations (MNCs) and the host states in which they operate, this study sought to contribute to general state-MNC relations by looking at the other dimension, namely home state-MNC relations. In addition, while home state-MNC literature mostly focuses on how this relationship plays out in the domestic realm; this study focused on home state-MNC relations in foreign policy. A further limitation was to only look at home state-MNC relations in the developing world by using China and Brazil as the main case studies, and their interaction with MNCs in foreign policy towards developing states from Africa. The research design was comparative, using the most similar system case selections.

  • Brazil and the Alliance for Progress
    BRAZIL AND THE ALLIANCE FOR PROGRESS: US-BRAZILIAN FINANCIAL RELATIONS DURING THE FORMULATION OF JOÃO GOULART‟S THREE-YEAR PLAN (1962)* Felipe Pereira Loureiro Assistant Professor at the Institute of International Relations, University of São Paulo (IRI-USP), Brazil [email protected] Presented for the panel “New Perspectives on Latin America‟s Cold War” at the FLACSO-ISA Joint International Conference, Buenos Aires, 23 to 25 July, 2014 ABSTRACT The paper aims to analyze US-Brazilian financial relations during the formulation of President João Goulart‟s Three-Year Plan (September to December 1962). Brazil was facing severe economic disequilibria in the early 1960s, such as a rising inflation and a balance of payments constrain. The Three-Year Plan sought to tackle these problems without compromising growth and through structural reforms. Although these were the guiding principles of the Alliance for Progress, President John F. Kennedy‟s economic aid program for Latin America, Washington did not offer assistance in adequate conditions and in a sufficient amount for Brazil. The paper argues the causes of the US attitude lay in the period of formulation of the Three-Year Plan, when President Goulart threatened to increase economic links with the Soviet bloc if Washington did not provide aid according to the country‟s needs. As a result, the US hardened its financial approach to entice a change in the political orientation of the Brazilian government. The US tough stand fostered the abandonment of the Three-Year Plan, opening the way for the crisis of Brazil‟s postwar democracy, and for a 21-year military regime in the country.

Fax: + 358 919124835. E-mail address: [email protected] Abstract The large-scale pulp investment model, with its pressure on land, has created conflict and caused major disagreements and open hostility amongst the social movement and NGO networks, state actors, and the pulp and paper companies in Brazil. In this article, Ethical Analysis was applied in the assessment of the dynamics and possibilities of conflict resolution related to the expansion of pulpwood plantations in Brazil's Bahia State, particularly near Veracel Celulose. Ethical Analysis as a tool identifies the complex dynamics of contention through identifying bridges and rifts in the social, ecological and economic viewpoints of the main actors. The analysis was based on field research, interviews, and a review of existing literature. The results indicated that the conflict is marked by politics of power, and as long as this stage continues, the politics of cooperation and conflict resolution would be hard to achieve.

I argue that the Democratization of the Brazilian healthcare system in 1988, created a conventional vision of the “New Brazilian (bio)Citizen” that has been institutionalized by the public healthcare system and reimagined or resisted by patients who seek care outside of the system. Rather than adopting the ontology of the New Brazilian (bio)Citizen as codified in the 1988 constitution, patients have built in additional ideas about the relationship between health, the self and their rights and responsibilities as citizens of Brazil and members of humanity.

  • Demographic Transition and the Regulatory Shortcomings of Brazil's
    DEMOGRAPHIC TRANSITION AND THE REGULATORY SHORTCOMINGS OF BRAZIL’S SOCIAL SECURITY Riovaldo Alves de Mesquita 1 Giácomo Balbinotto Neto 2 Resumo A assistência e previdência social brasileira são muito caras em relação ao perfil etário e de renda do país. Uma causa disso foi a indexação dos pisos de benefícios ao salário mínimo, feita na Constituição. Outras causas são a baixa idade de elegibilidade, os valores relativamente altos de benefícios, um período mínimo de contribuição relativamente curto, a possibilidade de os beneficiários acumularem mais de um tipo de benefício e o caráter assistencialista de alguns benefícios. Em 2050 os brasileiros com 65 anos ou mais serão 23% da população total e o número de pessoas em idade ativa estará em queda. Palavras-chave: Transição Demográfica, Previdência Social, Assistência Social. Abstract Brazil’s social security and social assistance provisions are too expensive and becoming more so relative to the country’s age profile and per capita GDP. One reason for this is the fact that in the1988 Constitution social security pensions were indexed to the minimum wage. Other reasons are low eligibility age, high pensions relative to past contributions, a short minimum contribution period, the possibility of accumulating different benefits and the fact that some social security benefits are dispensed as social assistance benefits. In 2050 Brazilians 65 or older will represent 23% of total population, while the workforce will be shrinking. Unless comprehensive reform is made in the country’s social provisions, they will become unsustainable. Keywords: Demographic Transition, Social Security, Social Assistance.

Part I, “Locating Representation”, argues that contemporary debates that privilege the creation of new democratic spaces as a response to the shortcomings of representative democracy ignore the importance of these spaces’ own issues of representation. The section goes on to outline the context for the research (which was conducted at the national level and in two sites in the Amazon region), describing the process of action research and multi-sited ethnography.

They are mainly associated with large sedimentary basins^ 'Brazilian uranium occurrences can be grouped into the following environments: (1) Metaconglomerates (2) Metasomatic rocks (associated with albitization) (3) Vein type (4) Sandstone type (5) Intrusive alkalic rock Upper Proterozoic folding regions related to mobile belts and large Precambrian unconformities are good targets for uranium exploration in Brazil. [QJJP»JT>\ I) INTRODUCTION The evolution of the earth's crust has an ensialic trend and uranium, as a lithophile element, follows this trend. It is progressively enriched during the formation of the continental crust. Due to its crystal chemistry uranium follows the classical magmatic differentiation, being gradually displaced to its late stages, reflected in the increase of the average content from ultramafic (0.03 ppmU) to acidic (3.8 ppmU) rocks. (25).It is well known that uranium does not participate in or substitutes other atoms in common rock-forming minerals. Uranium also does not form discrete minerals at conditions of high pressure and/or temperature, such as deep burial environments, within or close to intruded magmas.
