Migration, human capital accumulation and economic development

We study how the possibility of migration changes the composition of human capital in sending countries, and how this affects development. In our model, growth is driven by productivity growth, which occurs via imitation or innovation. Both activities use the same types of skilled labour as input, albeit with different intensities. Heterogenous agents accumulate skills in response to economic incentives. Migration distorts these incentives, and the accumulation of human capital. This slows down, or even hinders, economic development. The effect is stronger, the farther away the country is from the technological frontier. (C) 2008 Elsevier B.V. All rights reserved.

Global Governance and International Migration: A Case Study of Trafficking of Human Beings

The purpose of this article is to explore the concept of “global governance” and the way it applies to the management of international migration by using trafficking of human beings as a case study. Globalization has altered the scene of world politics. A traditional State-centric view of the world order has been overshadowed by the increasing importance of other actors, including the United Nations, multi-national corporations and non-governmental organizations. Globalization has also altered the dynamics of rule making and their enforcement within the international system, in that not only States but also these non-State actors exercise enormous influence. The concept of global governance acknowledges this as it aims to include all the pertinent actors involved. To illustrate this further, the author will use trafficking of human beings as a case study. Two key principles of global governance are participation and accountability. This article will analyse how these principles are reflected and implemented in the regime dealing with the prevention and suppression of trafficking of human beings.

Solid and liquid charge-transfer complex formation between 1-methylnaphthalene and 1-alkyl-cyanopyridinium bis{(trifluoromethyl)sulfonyl}imide ionic liquids

Liquid charge-transfer (CT) complexes were observed to form on contacting electron-rich aromatics with electron withdrawing group appended 1-alkyl-4-cyanopyridinium ionic liquids (ILs). Cooling below the melting point of the ionic liquid resulted in crystallisation of ionic liquid from the complex for 2-cyano and 3-cyano pyridinium isomers and in the formation of a 1 : 1 IL : aromatic crystalline CT-complex with the 4-cyanopyridinium isomer. The liquid structure of a 1 : 1 mixture of 1-methyl-4-cyanopyridinium bis{(trifluoromethyl)sulfonyl} imide with 1-methylnaphthalene has been probed by neutron diffraction experiments and molecular dynamics simulations. A high degree of correlation between the experimental data and the simulations was found with a significant displacement of the anions from around the cation by the aromatic species and the resulting structure having pi-pi stacks between the cations and the aromatic.
