Capital Flows Management During the Post-2007 Global Financial Crisis: The Experiences of SEACEN Economies
Although global financial stability in late 2010 and early 2011 has, in general, improved when compared to the 2008-2009 period of the sub-prime global financial crisis, vulnerabilities remain high. The recent World Economic Outlook of the IMF (WEO, September 2011) underlines the two speed recovery processes taking place in the world economies. In advanced economies, especially those hit hardest by the crisis, firms, government and household sectors continue to be heavily indebted and are likely to spur relatively weak demand. Although the financial markets of these economies have, in most parts, returned to profitability, the overall frail balance sheets reflect the general subdued state of the local economy. In sharp contrast, the emerging economies, including those of the SEACEN region, are posting robust growth rates until the second half of 2011, meeting new challenges associated with strong demand, rapid credit and excess liquidity. Price pressures, including potential asset price bubbles, have been the common themes of policy challenges for the SEACEN economies. Managing macro-financial risks, namely balancing growth, balance sheet soundness of the financial institutions, particularly the banking sector, and keeping a lid on inflationary pressures, have been and will likely be the primary policy challenges for these emerging markets in 2011 and 2012. This paper takes stock of recent trends and developments with regard to capital flows in the SEACEN economies. It elaborates in detail, the breakdowns and compositions of the flows. In particular, the focus of the analyses is on key flows such as the international bank lending activities to the region. The paper also summarises and analyses some of the basic push and pull factors of these flows to understand some of the domestic and external drivers of these flows. Some of the economic consequences of these capital flows and policy dilemma facing the SEACEN economies are also looked at. The paper also examines the policy responses of the central banks/monetary authorities, in particular, to mitigate the negative consequences and maximise the benefits of capital flows.
Analisis Faktor Yang Mempengaruhi Kebijakan Hutang Emiten Pertanian Di Bursa Efek Indonesia
In financial management perspective, corporate goal is to maximize shareholder or corporate value. The purpose of this study was to analyze the effect of institutional ownership (INST), asset structure (FAR), profitability (ROA), and corporate growth (GROWTH) on debt policy. This study used linear and multiple regression analysis. Significant test results of individual parameters (t statistical test) showed that significant value of INST variable 0.058 < 0.1 (α) and -0.632 (β), FAR 0.097 < 0.1 (α) and 1.019 (β), ROA 0.043 < 0.1 (α) and -1.198 (β), and GROWTH 0.064 < 0.1 (α) and 0.972 (β). The results showed that INST and ROA significantly and negatively affect debt policies, while FAR and GROWTH were significantly and positively affect on debt policies. Whereas, test result of simultaneous (F statistical test) showed that significant value was 0.010 < 0.1 (α) and the value of F calculated was 4.184 > 2.184 F table. These results indicated that institutional ownership, asset structure, profitability, and corporate growth had a significant effect on debt policy simultaneously
Measuring Ultrasonic Characterisation to Determine the Impact of Toc and the Stress Field on Shale Gas Anisotropy
While the majority of natural gas is produced from conventional sources, there is significant growth from unconventional sources, including shale-gas reservoirs. To produce gas economically, candidate shale typically requires a range of characteristics, including a relatively high total organic carbon (TOC) content, and it must be gas mature. Mechanical and dynamic elastic properties are also important shale characteristics that are not well understood as there have been a limited number of investigations of well-preserved samples. In this study, the elastic properties of shale samples are determined by measuring wave velocities. Arrays of ultrasonic transducers are used to measure five independent wave velocities, which are used to calculate the elastic properties of the shale. The results indicated that for the shale examined in this research, P- and S-wave velocities vary depending on the isotropic stress conditions with respect to the fabric and TOC content. It was shown that the isotropic stress significantly impacts velocity. In addition, S-wave anisotropy was significantly affected by increasing stress anisotropy. Stress orientation, with respect to fabric orientation, was found to be an important influence on the degree of anisotropy of the dynamic elastic properties in the shale. Furthermore, the relationship between acoustic impedance (AI) and TOC was established for all the samples

Density-Functional Theory of Graphene Sheets
We outline a Kohn-Sham-Dirac density-functional-theory (DFT) scheme for
graphene sheets that treats slowly-varying inhomogeneous external potentials
and electron-electron interactions on an equal footing. The theory is able to
account for the the unusual property that the exchange-correlation contribution
to chemical potential increases with carrier density in graphene. Consequences
of this property, and advantages and disadvantages of using the DFT approach to
describe it, are discussed. The approach is illustrated by solving the
Kohn-Sham-Dirac equations self-consistently for a model random potential
describing charged point-like impurities located close to the graphene plane.
The influence of electron-electron interactions on these non-linear screening
calculations is discussed at length, in the light of recent experiments
reporting evidence for the presence of electron-hole puddles in nearly-neutral
graphene sheets.Comment: 11 pages, 9 figures, submitted. High-quality figures can be requested

Di-μ-methacrylato-κ4 O:O′-bis[aquabis(1,10-phenanthroline-κ2 N,N′)copper(II)] dinitrate dihydrate
The title complex, [Cu2(C4H5O2)2(C12H8N2)2(H2O)2](NO3)2·2H2O, contains a dimeric [Cu2(C4H5O2)2(C12H8N2)2(H2O)2]2+ dication with two five-coordinated CuII ions linked by two methacrylate ions in a syn–syn bridging arrangement. The dication possesses pseudo-twofold rotational symmetry. The pentacoordination of each CuII ion has a distorted square-pyramidal geometry, with two N donors from a phenanthroline ligand and two carboxylate O atoms occupying basal sites and the apical position being occupied by a water molecule. In the crystal packing, molecules are linked to form a three-dimensional framework by O—H⋯O and C—H⋯O hydrogen bonds and π–π interactions [centroid–centroid distances of 3.6039 (15), 3.5301 (15), 3.6015 (15), 3.6496 (15) and 3.6858 (15) Å]
Isotropic Band Gaps and Freeform Waveguides Observed in Hyperuniform Disordered Photonic Solids
Recently, disordered photonic media and random textured surfaces have
attracted increasing attention as strong light diffusers with broadband and
wide-angle properties. We report the first experimental realization of an
isotropic complete photonic band gap (PBG) in a two-dimensional (2D) disordered
dielectric structure. This structure is designed by a constrained-optimization
method, which combines advantages of both isotropy due to disorder and
controlled scattering properties due to low density fluctuations
(hyperuniformity) and uniform local topology. Our experiments use a modular
design composed of Al2O3 walls and cylinders arranged in a hyperuniform
disordered network. We observe a complete PBG in the microwave region, in good
agreement with theoretical simulations, and show that the intrinsic isotropy of
this novel class of PBG materials enables remarkable design freedom, including
the realization of waveguides with arbitrary bending angles impossible in
photonic crystals. This first experimental verification of a complete PBG and
realization of functional defects in this new class of materials demonstrates
their potential as building blocks for precise manipulation of photons in
planar optical micro-circuits and has implications for disordered acoustic and
electronic bandgap materials
