The extended Delaunay tessellation (EDT) is presented in this paper as the unique partition of a node set into polyhedral regions defined by nodes lying on the nearby Voronoï spheres. Until recently, all the FEM mesh generators were limited to the generation of tetrahedral or hexahedral elements (or triangular and quadrangular in 2D problems). The reason for this limitation was the lack of any acceptable shape function to be used in other kind of geometrical elements. Nowadays, there are several acceptable shape functions for a very large class of polyhedra. These new shape functions, together with the EDT, gives an optimal combination and a powerful tool to solve a large variety of physical problems by numerical methods. The domain partition into polyhedra presented here does not introduce any new node nor change any node position. This makes this process suitable for Lagrangian problems and meshless methods in which only the connectivity information is used and there is no need for any expensive smoothing process.

Administrative reforms in Argentina have followed an irregular trajectory as a result of the penetration of patronage in the state apparatus. Extensive politicization has impeded the development of a univocal and stable civil service at the national level.

In this context, the goal of this chapter is to analyze the characteristics of the federal civil service in its interaction with actors and institutions of the political system during the 2004–2014 period. The study reveals two main findings: (1) a diversity of bureaucratic formats coexist in the country, both formally and informally; and (2) the relationships between the administration and the political system vary according to the predominant bureaucratic format.

Governance and opacity issues have increased since the early 1990s and several governance indicators are introduced by international organizations and NGOs. The governance indicators have been used in various sectors, directly affecting a nation's political reputation. This study analyzes the context of governance and opacity in Argentina and Chile and assesses the relationship between the cultural pattern and the functioning of institutions. A first approximation to the analysis of Argentina and Chile seems to lead to the conclusion of the existence of homogeneity between them as a result of a similar background. However, differences in geography and history generate different societal norms, and functioning of institutions within them. Chile's geographical isolation and limited natural resources leads the country toward economic growth and political stability. By contrast, in Argentina, populist regimes undermine the foundations of its economy while its middle class struggles and loses public trust. The various factors interactively affect quality of public policies and governance and, consequently, are conducive to differences in the perceived and real levels of opacity between both countries. Is corruption a culture-specific issue? If yes, then, is governance a consequence of culture too? Therefore, it is important to interpret a context behind governance in order to establish appropriate anticorruption reform in practice. This chapter seeks to address some of these issues by means of a case study comparison between Argentina and Chile and contribute to the understanding of the context in which negotiations may occur when FDI and M&A deals take place.

Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.
