Internal Governance Structures and Earnings Management
This paper investigates the role of a firm's internal governance structure in constraining earnings management. It is hypothesized that the practice of earnings management is systematically related to the strength of internal corporate governance mechanisms, including the board of directors, the audit committee, the internal audit function and the choice of external auditor. Based on a broad cross-sectional sample of 434 listed Australian firms, for the financial year ending in 2000, a majority of non-executive directors on the board and on the audit committee are found to be significantly associated with a lower likelihood of earnings management, as measured by the absolute level of discretionary accruals. The voluntary establishment of an internal audit function and the choice of auditor are not significantly related to a reduction in the level of discretionary accruals. Our additional analysis, using small increases in earnings as a measure of earnings management, also found a negative association between this measure and the existence of an audit committee.No Full Tex
Development and validation of a new Fourier transform infrared spectrometric method for the quantification of urea in creams and ointments
A new Fourier transform infrared (FTIR) spectrometric method for the quantification of urea in creams and ointments was developed and validated. The sample was solubilized in a mixture of chloroform/acetonitrile (1/1 v/v) which allows to solubilize the vaseline or other fats as well as urea and water. The solution was examined in a transmission cell with a pathlength of 500 μm provided with NaCI windows. The urea spectrum was obtained by subtraction of the reference solvent mixture spectrum and the reference water spectrum from the sample spectrum. The absorbance of the peak at ±1688 cm-1 was compared to those of calibration standards to quantify urea. The detection limit and the quantification limit (three times and 10 times the noise, respectively) were estimated as 0.4 and 1.3 μg ml-1, respectively. Validation of the method was realized and application of this method to stability tests was done
