Cash holding in businesses depends largely on their resource management because operational activities in a period which usually lasts one year concern the recognition and optimal management of working capital. The working capital is not primarily determined to increase profits but managers try to obtain a favorable level of liquidity so that they can meet the company’s profitability goals. This article aims to explain the relationship between consumer price index (CPI), operating cycle, and size and growth opportunities with cash holding in Tehran stock Exchange. To achieve this goal, 75 companies listed in Tehran Stock Exchange whose financial data were accessible from 2012 to 2016 were selected as the research sample. The results indicated that CPI and the operating cycle have no significant relationship with cash holding. In addition, the analysis of other variables suggested that the firm size, net changes in working capital, changes in current liabilities, and cash holding have a significant relationship with cash holding. Finally, the results of this study showed that there is a significant relationship between the company size and cash holding, while growth opportunities do not show any significant correlation with cash holding.

This paper aims at highlighting the role of the XBRL in electronic accounting disclosure and how it contributes to the activation and efficiency of the stock market, in order to increase the awareness of Algerian institutions to the need of introducing this new technology in the accounting disclosure process. And consequently, to increase the quality of the financial reports, transparency and the integrity, because these latter is considered to be the backbone of confidence in both the financial and nonfinancial communities.

To achieve our goal, we conducted a field study to validate our plan above.The questionnaire was distributed to some practitioners in countries that applied the"XBRL" language (Malaysia, South Africa, Romania, Oman...). As we intended, first of all, to appreciate the tight relation between the language "XBRL" and the quality of the financial information.

Tax evasion has always being a bane to any tax system and there are diverse arguments on tax audit and investigation as a curb to this anathema. Based on this, the study examined the application of tax audit and investigation on tax evasion control in Nigeria. It specifically investigated the impact of desk audit-DEKAUD, field audit-FIAUD, back duty auditBAKAUD and tax investigation-TAXINV on tax evasion control in Nigeria. Relevant data was sourced fromthe administration of questionnaire and response from it analyzed with ordered logistic regression and Spearman's rho measure of association. It was revealed that from the Likelihood ratio test: Chisquare(4)= 325.11 [0.0000] and cut1 to cut11 that the overall model is significant at 5% levelin explaining the variation in tax evasion control in Nigeria. DEKAUD has a tendency to significantly reduce the occurrence of tax fraud in Nigeria (z=5.8743, p<0.00001); FIAUD indicated effect of 0.14 (z=, p=0.15720) on tax evasion control in the country; BKAUD showed significant influence on the control of tax evasion (z=4.1856, p<0.05); Tax investigation does not influence significantly the level of fraud control (z= 1.1017, p>0.05).It was concluded that tax audit in the form of desk and back duty are highly instrumental in the reduction in tax evasion, while tax investigation and field audit does not influence the control of tax frauds in the form of evasion. The study recommended that revenue agency should frequently engage in desk and field audit as they both contribute largely to the control of tax evasion in the country, while in the conduct of field audit and tax investigation, they must put in place adequate machinery in the form security personnel to help protect tax inspectors so as to mitigate the occurrence of fracas between tax inspectors and tax evaders which makes it impact not to be felt on tax evasion control.

Linearization of portfolio optimization plays a central role in financial studies, since linear problem allows for performing sensitivity analysis. This concept makes it possible to measure the variation of parameters as a result of variation of one parameter in a linear problem, without solving the problem from scratch. Based on the existing literatures, the approach of CVaR (conditional value at risk) method outperforms other methods, therefore in this study CVaR is applied as a constraint to change portfolio optimization problem into a linear problem. The coefficient of objective function of mentioned method for a portfolio includes average of asset returns, which are highly correlated. Here principal component analysis is employed to convert the correlation of the functional relations. An example of stock market is employed to substantiate the validity of method. Finally, we verify that the result of the presented method is closer to the ideal result.
