The international system is changing fast and both the European Union and Brazil will need to adapt. This paper argues that such a process of adjustment may bring the two closer together, even if their starting points differ considerably. Europe looks at the ongoing redistribution of power as a challenge, Brazil as an opportunity. Europe is coping with the detrimental impact of the economic crisis on its international profile; Brazil is enhancing its influence in its region and beyond. Their normative outlook is broadly compatible; their political priorities and behaviour in multilateral frameworks often differ, from trade to development and security issues. Despite the crisis, however, there are signals of renewed engagement by the EU on the international stage, with a focus on its troubled neighbourhood and partnerships with the US and large emerging actors such as Brazil. The latter is charting an original course in international affairs as a rising democratic power from the traditional South with no geopolitical opponents and a commitment to multilateralism. In testing the limits of its international influence, Brazil will need dependable partners and variable coalitions that go well beyond the BRICS format, which is not necessarily sustainable. This contribution suggests that the strategic partnership between the EU and Brazil may grow stronger not only as a platform to deepen economic ties and sustain growth, but also as a tool to foster cooperation in political and security affairs including crisis management, preventive diplomacy and human rights.

Many commentators have criticised the strategy used to finance regional governments such as the Scottish Parliament – both the block grant system and the limited amount of fiscal autonomy devised in the Scotland Act of 2012. This lecture sets out to identify what level of autonomy or independence would best suit a regional economy in a currency union, and also the institutional changes needed to sustain those arrangements. Our argument is developed along three lines. First, we set out the advantages of a fiscal federalism framework and the institutions needed to support it, but which the Euro-zone currently lacks. The second is to elaborate a model of fiscal federalism where comprehensive powers of taxation and spending are devolved (an independent Scotland and the UK remain constituent members of the EU and European economy). Third, we evaluate the main arguments for the breakup of nations or economic unions with Scotland and the UK as leading examples. We note that greater autonomy may not result in increases in long run economic growth rate, but it does imply that enhancing the fiscal competence and responsibility of regional governments would result in productivity gains and hence higher levels of GDP per head. That means the population is permanently richer than before, even if ultimately their incomes continue to grow at the same rate. It turns out that these improvements can be achieved through devolved tax powers, but not through devolved spending powers or shared taxes.

International trade and investment economies are highly integrated and interdependent and can be exploited by organized, international terrorism. The network of inter dependencies in the international economy means that a terrorist attack has the potential to disrupt the functioning of the network, so the effects can reverberate around the world. Governments can control the distributed effects of terrorism by auditing industrial networks to reveal and protect critical hubs and by promoting flexibility in production and distribution of goods and services to improve resilience in the economy. To explain these network effects, the authors draw on the new science of complex networks which has been applied to the physical sciences and is now increasingly being used to explain organizational and economic phenomena.

Since Plato's Republic and Aristotle's Politics established the basis for Western political thought almost 2500 years ago, the discipline of international relations has evolved substantially. However, most of the literature revolves around state interaction within the system, and there is little discussion of countries that opt out of the international states system and become isolationist. Given the interdependent nature of the modern international system, this study elaborates on domestic and foreign isolationism by expounding upon the reasons and consequences of states opting out of the international system. The empirical case studies utilized to explore isolationism are Albania, North Korea, and Burma. By empirically verifying the components, motivations, and consequences of isolationism in an interdependent world, this study provides insight into why and how states resist engagement with the global socioeconomic and political state system. ^ Using historical, comparative, and inductive analysis, this study explains why states choose to isolate themselves both domestically and internationally. Specifically, comparative historical analysis highlights isolationism as a concept and practice. This study maintains that extreme forms of self-imposed isolation in an interdependent international system, while perhaps serving the immediate interests of a ruling regime, harms the long-term national interests of the state and the populace. Although the leadership in an isolationist state gains a significant amount of power and control over the people within its borders, the state as a whole experiences profound negative effects. In the long term, a state loses power, stability, prestige, and suffers a decline in overall economic prosperity. ^ States that withdraw from the international system, therefore, provide insight into an unexplored area of international relations when considering notions of rationality, self-interest, power politics, cooperation, and alliances. In short, isolationism in an interdependent state system goes against the logic of the modern society/system of states, resulting in deleterious consequences to the wellbeing of the state. ^

Bangladesh has experienced rising GDP and rising per capita incomes now for at least three decades. This article considers whether its continuing economic growth is likely to solve its environmental problems. In doing so, it critically considers the application to Bangladesh of Environmental Kuznets Curve relationships and applies other macro-methods of assessing the relationship between economic growth and the environment to Bangladesh’s situation. The consequences of Bangladesh's economic reforms for the economic welfare of Bangladeshis and the state of Bangladesh's environment are also examined. Particular attention is given to environmental change in agriculture in the light of Bangladesh economic growth, reforms and proposed growth strategy. Doubts are expressed about the environmental benefits claimed by the Bangladeshi Government for its agricultural development strategy. Indeed, it may exacerbate many existing environmental problems, such as depletion of soil fertility and water supplies, already present.

Variational data assimilation is commonly used in environmental forecasting to estimate the current state of the system from a model forecast and observational data. The assimilation problem can be written simply in the form of a nonlinear least squares optimization problem. However the practical solution of the problem in large systems requires many careful choices to be made in the implementation. In this article we present the theory of variational data assimilation and then discuss in detail how it is implemented in practice. Current solutions and open questions are discussed.

We propose an iterative procedure for the inverse problem of determining the displacement vector on the boundary of a bounded planar inclusion given the displacement and stress fields on an infinite (planar) line-segment. At each iteration step mixed boundary value problems in an elastostatic half-plane containing the bounded inclusion are solved. For efficient numerical implementation of the procedure these mixed problems are reduced to integral equations over the bounded inclusion. Well-posedness and numerical solution of these boundary integral equations are presented, and a proof of convergence of the procedure for the inverse problem to the original solution is given. Numerical investigations are presented both for the direct and inverse problems, and these results show in particular that the displacement vector on the boundary of the inclusion can be found in an accurate and stable way with small computational cost.
