Foreign Direct Investment flows to countries where the most prominent political parties are national, rather than regional

What is the relationship between Foreign Direct Investment (FDI) and political party organisation? Joel W. Simmons, Allen Hicken, Ken Kollman and Irfan Nooruddin share evidence which shows that countries with a higher number of regionalised political parties will have more difficulty attracting FDI than those countries with national political parties in positions of greater prominence

Wang-Landau molecular dynamics technique to search for low-energy conformational space of proteins

Multicanonical molecular dynamics (MD) is a powerful technique for sampling conformations on rugged potential surfaces such as protein. However, it is notoriously difficult to estimate the multicanonical temperature effectively. Wang and Landau developed a convenient method for estimating the density of states based on a multicanonical Monte Carlo method. In their method, the density of states is calculated autonomously during a simulation. In this paper we develop a set of techniques to effectively apply the Wang-Landau method to MD simulations. In the multicanonical MD, the estimation of the derivative of the density of states is critical. In order to estimate it accurately, we devise two original improvements. First, the correction for the density of states is made smooth by using the Gaussian distribution obtained by a short canonical simulation. Second, an approximation is applied to the derivative, which is based on the Gaussian distribution and the multiple weighted histogram technique. A test of this method was performed with small polypeptides, Met-enkephalin and Trp-cage, and it is demonstrated that Wang-Landau MD is consistent with replica exchange MD but can sample much larger conformational space.Comment: 8 pages, 7 figures, accepted for publication in Physical Review

Political Parties and Electoral Landscapes

We study the relationship between voters' preferences and the emergence of party platforms in two-party democratic elections with adaptive parties. In the model, preferences of voters and the opposition party's platform determine an electoral landscape on which the challenging party must adaptively search for votes. We show that changes in the underlying distribution of voters' preferences result in different electoral landscapes which can be characterized by a measure of ruggedness. We find that locally adapting parties converge to moderate platforms regardless of the landscape's ruggedness. Greater ruggedness, however, tempers a party's ability to find such platforms. Thus, we are able to establish a link between the distribution of voters' preferences and the responsiveness of adaptive parties

Can Government-Controlled Media Cause Social Change? Television and Fertility in India *

Abstract Does exposure to government-controlled media shape social attitudes and behaviors? Governments routinely enlist public broadcasting to advance progressive social change. However, the efficacy of so-called "developmental communications" is unclear. Modernization theorists contend that the media serve as an important instrument of persuasion in poor countries-especially among certain population groups. Yet, where institutionalization is weak, government-controlled outlets are often dominated by ruling-party propaganda, which may induce distrust in the media and its messaging campaigns. To adjudicate which of these propositions holds sway, we investigate television's impact on fertility preferences and behaviors in India. Exploiting unique data, as well as plausibly exogenous variation in TV ownership due to electromagnetic wave refraction, we show that exposure to India's monopolistic state broadcaster, Doordarshan, caused women to desire fewer children-especially fewer girls-while increasing family planning discussions and contraceptive use. The results demonstrate that even biased state media can engender far-reaching societal transformation. * We than
