The Role of Physical, Human and Social Capital in Regional Financial Development Differences: An Analysis of Turkish Provinces
The Role of Physical, Human and Social Capital in Regional Financial Development Differences: An Analysis of Turkish Provinces Ercan Dulgeroglu , Sibel Bali Eryigit , Kadir Y. Eryigit and Filiz Gaygusuz Abstract With the undeniable importance of the financial markets in the economy, the factors stimulating financial development have started to be researched, particularly in recent times in a more intensive way. Starting from this point, the driving force of this study is both to contribute to international literature in this field and to fill a gap in the literature related to Turkey. The main purpose of this study is to explain the causes of regional financial development differences on the basis of capital accumulation. In order to answer the question âWhat is the effect and degree of importance of physical, human and social capital on the differences in regional financial development?â, in this study some indexes for financial development and each type of capital accumulation will be calculated using kernel principle components analysis and depending on the annual data of 81 provinces covering the period 2005 â 2009. As an index, the capital measurements can be seen in a comprehensive form allowing for more accurate measurement and evaluation of both the capital accumulation and financial development. By using the calculated indexes, then, financial development differences are evaluated with spatial panel data methods developed by Elhorst (2003). In this context, to our knowledge, this study is the first to take into account the effects of each type of capital on financial development in a model simultaneously.

Scaling of the critical temperature and quark potential with a renormalization group improved SU(3) gauge action
We study the scaling property of the ratio of the critical temperature
to the square root of the string tension in the SU(3) pure gauge
theory using a renormalization group improved action. We first determine the
critical coupling on lattices with temporal extension and 6,
and then calculate the static quark potential at the critical couplings on
lattices at zero temperature. The values of in the
infinite volume limit are identical within errors, while they are slightly
larger than the value extrapolated to the continuum limit with the standard
action. We also note that the rotational invariance of the static quark
potential is remarkably restored in the both cases, and that the potential
in physical units scales in the whole region of investigated.Comment: 3 pages of Latex, 5 PostScript figures, Talk presented at

Comparing the QCD potential in Perturbative QCD and Lattice QCD at large distances
We compare the perturbatively calculated QCD potential to that obtained from
lattice calculations in the theory without light quark flavours. We examine
E_tot(r) = 2 m_pole + V_QCD(r) by re-expressing it in the MSbar mass m =
m^MSbar(m^MSbar) and by choosing specific prescriptions for fixing the scale mu
(dependent on r and m). By adjusting m so as to maximise the range of
convergence, we show that perturbative and lattice calculations agree up to
3*r_0 ~ 7.5 GeV^-1 (r_0 is the Sommer scale) within the uncertainty of order
Lambda^3 r^2.Comment: Version to appear in Eur.J.Phys; 16 pages, 7 figure
A fresh look on the flux tube in Abelian-projected SU(2) gluodynamics
We reconsider the properties of the flux tube within
Abelian-projected SU(2) lattice gauge theory in terms of electric field and
monopole current. In the maximal Abelian gauge we assess the influence of the
Gribov copies on the apparent flux-tube profile. For the optimal gauge fixing
we study the independence of the profile on the lattice spacing for
2.3, 2.4, and 2.5115 on a lattice. We decompose the Abelian Wilson loop
into monopole and photon parts and compare the electric and monopole profile
emerging from different sources with the field strength and monopole current
within the dual Ginzburg-Landau theory.Comment: 3 pages, 6 figures, Lattice2002(topology
Thermodynamics and heavy quark potential in N_f=2 dynamical QCD
We study N_f=2 lattice QCD with nonperturbatively improved Wilson fermions at
finite temperature on 16^3 \cdot 8 lattices. We determine the transition
temperature at m_{\pi}/m_{\rho} \sim 0.8 and lattice spacing as small as
0.12fm. The string breaking at T < T_c is also studied. We find that the static
potential can be fitted by a simple expression involving string model potential
at finite temperature.Comment: 6 pages, 6 figures, contribution to Lattice 2002(topology
Quark Confinement Physics in Quantum Chromodynamics
We study abelian dominance and monopole condensation for the quark
confinement physics using the lattice QCD simulations in the MA gauge. These
phenomena are closely related to the dual superconductor picture of the QCD
vacuum, and enable us to construct the dual Ginzburg-Landau (DGL) theory as an
useful effective theory of nonperturbative QCD. We then apply the DGL theory to
the studies of the low-lying hadron structure and the scalar glueball
properties.Comment: Talk given at 15th International Conference on Particle and Nuclei

Observing Long Colour Flux Tubes in SU(2) Lattice Gauge Theory
We present results of a high statistics study of the chromo field
distribution between static quarks in SU(2) gauge theory on lattices of volumes
16^4, 32^4, and 48^3*64, with physical extent ranging from 1.3 fm up to 2.7 fm
at beta=2.5, beta=2.635, and beta=2.74. We establish string formation over
physical distances as large as 2 fm. The results are tested against Michael's
sum rules. A detailed investigation of the transverse action and energy flux
tube profiles is provided. As a by-product, we obtain the static lattice
potential in unpreceded accuracy.Comment: 66 pages, 29 figures, uuencoded latex file with epsfigures (450 K),

Structure of the baryonic flux tube in N_{f}=2 lattice QCD at finite temperature
We study the flux tube profile in the baryonic system in full QCD at finite
temperature on lattice. We fix the maximally Abelian gauge and
measure the monopole and the photon parts of the Abelian action density, the
color electric field and the monopole current on both sides of the finite
temperature transition. We demonstrate the disappearance of the flux tube in
the high temperature phase.Comment: 3 pages, 4 figures, Lattice2003 topolog
