The uneven regional distribution of foreign direct investment (FDI) in Turkey poses an interesting question from the perspective of multinational firms (MNFs) and policymakers alike. This paper focuses on the factors governing the location decision of MNFs within Turkey with specific reference to policy implications. Using a conditional logit model, we find that agglomeration, depth of local fi...
We present converged first-principles calculations for the atomic and electronic structure of diamond ~111! surfaces based on density-functional theory in the local-density approximation. Singleand triple-danglingbond surfaces with 131, 231, and (A33A3)R30° translational symmetry are studied by means of totalenergy minimizations. The ground-state geometries and electronic band structures are co...
We study the O/Pd 111 system using a lattice-gas Hamiltonian where the many-body interactions among the oxygen adsorbates are derived from a series of density-functional-theory calculations. Through Monte Carlo simulations that employ the Wang-Landau algorithm, we use this Hamiltonian to predict the order-disorder phase-transition temperature as a function of oxygen coverage. We find that oxyge...
Scanning tunnelling microscopy has been used to study the effect of ion bombardment at different angles of incidence on a graphite surface. The 246 MeV energy of Kr+ ions was selected in the medium energy range, where the electronic and nuclear stopping is nearly balanced. The low dose (1 x 10(12)/cm2) of ions allows the characterization of single features caused by bombardment in perpendicular...
The formation of interface dipoles in self-assembled monolayers (SAMs) of –CH3 and –CF3 terminated short-chain alkanethiolates on Ag(111) is studied by means of density functional theory calculations. The interface dipoles are characterized by monitoring the change in the surface work function upon adsorption of the SAM. We compare results obtained for SAMs in structures with a different packin...
To resolve the phylogeny of the autochthonous mitochondrial DNA (mtDNA) haplogroups of India and determine the relationship between the Indian and western Eurasian mtDNA pools more precisely, a diverse subset of 75 macrohaplogroup N lineages was chosen for complete sequencing from a collection of >800 control-region sequences sampled across India. We identified five new autochthonous haplogroup...
Lucas and Rossi-Hansberg (2002) and Fujita and Ogawa (1982, 1989) develop urban models in which economic activity self-organizes due to spillovers in production. However, Fujita and Ogawa (1982, 1989) show that rents and employment density are flat or falling as the city center is approached, while in the simulations of Lucas and Rossi-Hansberg (2002) rents rise at an increasing rate towards th...
In the present paper we report in detail the results of our first-principles investigations of Xe/metal adsorption systems which were briefly presented in an earlier publication. We investigate Xe adsorption on the Mg 0001 , Al 111 , Ti 0001 , Cu 111 , Pd 111 , and Pt 111 surfaces in the 3 3 R30° structure. Our calculations are based on density functional theory within the local-density approxi...
A central purpose of this chapter is to assess whether the available empirical evidence supports the view that current levels of housing discrimination are a significant contributor to residential segregation in U.S. cities and metropolitan areas. Through the course of this chapter, the reader will find that the empirical patterns of racial segregation in the U.S. are often inconsistent the ava...
