Reza Zare,Javad Moradi,Hashem Valipour
Asian Economic and Financial Review , 2013,
Abstract: This study attempts to examine the relevance of dividend policy and information asymmetry From the Signaling Perspective and Compare the relative information content of them. Based on sampling, 88 firms from Tehran Stock Exchange (TSE) were selected and examined during 2003 to 2010. The findings show that the profit division policy(Divisible profit proportion) has positive and significant relation with market data asymmetry namely when the profit division policy increases the data asymmetry increases, too. On the other side, the test findings indicate the investors are sensitive to the EPS changes and when the EPS changes are positive their divisible profit increases, but when the divisible profit of the company decreases the data boggles their mind and data asymmetry increases.

Javad Moradi,Hashem Valipour,Aida Dowran
Research Journal of Applied Sciences, Engineering and Technology , 2013,
Abstract: This study examines the value relevance (information content) of cash flow and accounting figures in situations where the information is asymmetrical and Compare the relative information content of them to clarify the role of accounting figures in investment decision making and mitigating the agency problems (specifically resulting from the existence of information asymmetry in the emerging markets). Based on testing a sample of 76 firms from Tehran Stock Exchange (TSE) during 2005 to 2011, the results support the priority of accounting figures over cash flows in the market (TSE). On the other hand, when the information is asymmetrical, the accounting figures are still more relevant than the cash flows and have more relative information content. At the same time, in small firms, the value relevance of the accounting figures compared to cash flows is more; while in large firms, the relative content of accounting figures and cash flow figures aren't significantly different.

Research Journal of Applied Sciences, Engineering and Technology , 2012,

The effect of various factors on the assessment scale of operation was measured in different researches, e.g. the structure of ownership. In this study, the relationship between three kinds of various structures of ownership including the structure of shareholder's ownership and other firms and the structure of state ownership Q Tobin's operation scale of listed firms in TSE was considered. The effect of firm's age and size has considered as two control variables on the Q Tobin's operation scale. In this study, the statistical population is listed firms in Tehran Stock Exchange (TSE). Theories are tested by multilateral Regression on the basis of T and F statistics. Finding shows that Q Tobin operation scale has significant relationship with two kinds of investment organization's ownership scale and other companies and state ownership, but it does not have significant relationship with minor shareholder's scale. Age and size of firms do not effect on Q Tobin operation scale as two control variables.

Reza Tehrani,Mahdi Salehi,Hashem Valipour,Mohammad Jahandar Lashky
Business Intelligence Journal , 2009,
Abstract: The political cost is one of the most important costs and payment of companies, and companies sought to reduce these costs. According to the theory that political expenditures by Watts and Zimmerman has been presented, Politicians have the power to by using the policies of the distribution of wealth again such as taxes, aid, the contributions, insurance and etc companies under the influence of. In other words, the change in currents can cash by taxes, special rules and information pertinent to the political challenges under the influence of. The aim of this research study is the relationship between the size of the company and the political costs. To do research the historical information of all present companies in Tehran stock exchange in the period of time 2005 to 2007 has been used. In the way of analyze information after making dependent conversional normal, seeing transmittal charts and with regard to the index R2, logarithmic models have been selected for the expression of communication. The results of different patterns show that relation between the size of company and political costs is meaningful. It means that by increasing the costs of the company as much as political as well as it will increase. On the other hand because companies' environment in political activities and many of the cost of the political support by law, so a big part of the political challenges that the companies will be imposed is unavoidable and another part of it like celebration relations and the cost for participation in elections and help and contributions have been impossible to control and it can be with proper management and precise auditing by considering the long-term works reduced them.

Mohammad Valipour
Journal of Agricultural Science , 2012, DOI: 10.5539/jas.v4n12p125
Abstract: Accurate computing of amount of pressure loss is very important in sprinkle and trickle irrigation system design. Not correctly adjusted of pressure loss are causes lack of appropriate performance or failure of sprinkle and trickle irrigation system. By tapered pipes, pressure loss adjusted using increasing or decreasing of pressure head. In this study using HydroCalc software, ability of single and tapered pipes in pressure loss adjusting has been compared. Single and tapered laterals were able to adjusting of pressure loss but single manifolds were not able to achieving to the desired pressure head. In single lateral-tapered manifold system due to the lower pressure loss in laterals, can be use from several types of pipe diameters for manifolds but in tapered lateral-tapered manifold system due to the more pressure loss in laterals, the choice is limited. The best diameters for tapered manifolds with single lateral were 69.2-36.8 mm, 69.2-58.2-36.8 mm, and 58.2-46.0-36.8 mm whereas the best diameters for tapered manifold with tapered lateral were 69.2-46.0-36.8 mm.
