The aim of this study is to investigate the affect of firm size on profitability. In this study, data of 200 companies which were active in Istanbul Stock Exchange (ISE) between the years 2008-2011 has been used. “Return on Assets” (ROA) has been used as indicators of firm profitability and total assets, total sales and number of employees have been used as indicators of size. Multiple regressi...

This article investigates the relationship between firm specific factors and macroeconomics on profitability in Taiwanese property-liability insurance industry using the panel data over the1999 through 2009 time period. Using operating ratio and return on assets (ROA) for the two kinds of profitability indicators to measure insurers’ profitability. The results show that underwriting risk, reins...

This paper examines the relationship between financial risks and profitability of the conventional and Islamic banks in Malaysia for the period between 1996 and 2005. The measures of profitability that have been used in the study are the return on equity (ROE) and return on assets (ROA) while the financial risks are credit risk, interest rate risk and liquidity risks. This study employs panel d...

Determination of the saccharide structure in solution is a laborious process that can be significantly enhanced by optical spectroscopies. Raman optical activity (ROA) spectra are particularly sensitive to the chirality and conformation. However, the interpretation of them is largely dependent on computational tools providing a limited precision only. To understand the limitations and the link ...

Transfers of polarizability, dipole, and energy derivatives from smaller fragments enable extension of ab initio vibrational spectral simulations to larger molecules. The accuracy of the transfer, however, varies according to the molecule and the tensor type. Recent works (J. Chem. Theory Comput.2011, 7, 1867 and Coll. Czech. Chem. Commun.2011, 76, 567) questioned the accuracy of the tensor tra...

The poly(l-proline) II (PPII) helix is considered to be a major conformation in disordered polypeptides and unfolded proteins in aqueous solution. The PPII conformation can be identified by using Raman optical activity (ROA), which measures the different intensities of right- and left-circularly polarized Raman scattered light from chiral molecules and provides information on stereochemistry as...

The formation and structure of the potassium complex with valinomycin in solution were studied by means of Raman and Raman optical activity (ROA) spectroscopy. The complexation caused significant spectral changes, particularly in the region 1200-1400 cm(-1). The experimental spectra were interpreted using first principles computations. A complete computational conformational search combined wit...

The C(2)-symmetric title compound, a small, rigid hydrocarbon molecule with two distinct, strongly interacting vibrational chromophores, represents a unique model system for testing computational approaches to Raman optical activity (ROA) beyond the isolated molecule and the harmonic approximation. We show that the experimental Raman and ROA spectra are marked by the presence of strong Fermi re...

Spectral comparison is an important part of the assignment of the absolute configuration (AC) by vibrational circular dichroism (VCD), or equally by Raman optical activity (ROA). In order to avoid bias caused by personal interpretation, numerical methods have been developed to compare measured and calculated spectra. Using a neighbourhood similarity measure, the agreement between a computed and...

INTRODUCTION Aggrecanase cleavage at the (392)Glu-(393)Ala bond in the interglobular domain (IGD) of aggrecan, releasing N-terminal (393)ARGS fragments, is an early key event in arthritis and joint injuries. We determined whether synovial fluid (SF) levels of ARGS-aggrecan distinguish subjects with progressive radiographic knee osteoarthritis (ROA) from those with stable or no ROA. METHODS We...
