By combining new data on bilateral asset holdings with data on securities regulation in an empirical gravity model, it is found that bilateral differences in securities regulation lead to decreased portfolio holdings. Hence, regulatory harmonization can foster financial integration. The results are especially strong for equity holdings. It is verified that the results do not just reflect genera...

This paper provides an original study into how democratization and globalization in‡uence transnational terrorism — examining the motives of terrorists and how democratic institutions and international integration in‡uence non-state economic actors. We employ a gravity model to investigate the relative importance of globalization and democratization on transnational terrorism and external con‡i...

We consider solutions of the field equations for the large N dilaton gravity model in 1 + 1 dimensions of Callan, Giddings, Harvey, and Strominger (CGHS). We find time dependant solutions in the weak coupling region with finite mass and vanishing flux, as well as solutions with lie entirely in the Liouville region.

We show that a canonical transformation converts, up to a boundary term, a generic 2D dilaton gravity model into a bosonic string theory with a Minkowskian target space.

The trade of livestock is an important and growing economic sector, but it is also a major factor in the spread of diseases. The spreading of diseases in a trade network is likely to be influenced by how often existing trade connections are active. The activity α is defined as the mean frequency of occurrences of existing trade links, thus 0 < α ≤ 1. The observed German pig trade network had an...

DYOPTYKA’s innovative solution for the reduction of speckle noise in projection displays, using a phase randomizing deformable mirror, is shown to achieve good performance both within a single 1 μs pulse duration and through sequences of such pulses.

Present paper is an attempt to estimate the impact of Economic and Geographic indicators in trade among Islamic countries according to a bilateral trade model as Gravity model, and study the relationship between Economy, Geography and Trade in this way. Fixed effect version of the panel data estimation producer with OIC member country data spanning over the 2007–2012. The result of this researc...
