Since judgments of many stakeholders such as investors and shareholders about the position of the economic unit are based on liquidity situation, so predicting future cash flow is crucial. In this research, the impact of cash and accrual items on cash flow forecasts has been studied. Providing a proper model to predict operating cash flows and review some important characteristics of cash flow forecasting regression models, using a multilayer perceptron and determining the best model by using accrual regression model variables for predicting cash flows. For this purpose, 287 firms listed in Tehran Stock Exchange during 2008 to 2017 were studied; Linear and nonlinear regression, correlation coefficient and artificial neural network statistical methods have been used for data analysis and predictive power of powers was c...

The behavioral factors affecting investment decisions are investigated in the area of behavioral finance. In other words, behavioral finance focuses on specific human behavior attributes and their utilization in asset pricing. Behavioral asset pricing is the result of applying behavioral finance theories within traditional asset pricing theories. Although there are many asset-pricing models, due to their weaknesses and incompleteness as well as the necessity of investigating behavioral factors, this study attempted to model asset pricing using behavioral models.The population of the study included all listed firms in Tehran Stock Exchange over the years 2008 to 2018, and the sample was selected through systematic elimination of the population. Given these conditions, 141 firms were selected as the sample. The hypotheses were then tested by designing multivariate regression models.The results showed that using Fama-Macbeth approach, accounting information risk, investors' trading behavior, and investors' sentiments had a significant and direct impact on firms' stock returns.Thus, it is argued that behavioral variables can play a significant role in Modeling Asset Pricing.

So, the components of psychological capital, including self-confidence, hope, optimism and resilience, and their impact on the operational performance of the subsidiary firms of Parsian Bank were studied. The results obtained from regression analysis of the firms’ data, at the confidence level of .95 and usingthepanel model with fixed effects, suggest that the components of psychological capital have a direct influence on the operational performanceof the subsidiary firms of Parsian Bank.

Investigating the factors affecting investment decisions is carried out in the field of behavioral finance; in other words, the focus of behavioral finance is on the specific charac-teristics of human behavior and applying them in asset pricing. Empirically, pricing models rarely include psychological factors, but the noticeable point is that nowadays, researchers have found behavioral factors influencing empirical asset pricing models that can manipulate returns on asset mispricing. Behavioral asset pricing is the result of applying behavioral finance theories within traditional asset pricing theories. Thus, despite the existence of many asset pricing models, due to their weaknesses and lack of comprehensiveness, as well as the necessity of reviewing behavioral factors, this study aims to model asset pricing through behavioral models. Using the data from 141 listed firms in Tehran Stock Exchange over the years 2008 to 2017 and multivariate regression, this study is an attempts to model asset pric-ing through employing behavioral models and Fama-French approach. Using Fama-French approach, the results showed that accounting information risk, investors' trading behavior, and investors' sentiment have a direct and significant impact on asset pricing.

The information contained in audit reports is used to forecast corporate bankruptcy; therefore, the auditor's opinion influences the views of users of financial statements. Financial status of a business can be assessed using financial ratios. The circumstances considered by an auditor in commenting on financial distress including financials (in particular, short-term liquidity, ability to repay and debt tolerability), and operations (profitability and ability to generate cash from operations). This study uses an integrated ANN-PSO to forecast audit opinion. The results show that ANN-PSO is more useful, because PSO algorithm can optimise hidden layers and neurons in ANN simultaneously. Finally, ANN-PSO outperforms ANN.

Materials and Methods: Male BALB/c mice were randomly divided into 12 groups composing sham, control, and treated groups. Aging was induced by administration of D-galactose (500 mg/kg/day for 6 weeks). A positive control group was assigned that received vitamin E (200 mg/kg/day). The extract of herbs was prepared, lyophilized, and used in this study. The herbs were administered by gavage for 4 weeks to D-galactose-aged animals at the selected doses (mg/kg/day) as follows: Zingiber officinale (250), Glycyrrhiza glabra (150), Rosmarinus officinalis (300), Peganum harmala (50), Aloe vera (150), Satureja hortensis (200), Teucrium scordium (200), Hypericum perforatum (135) and Silybum marianum (150). One group of animals was assigned as sham and not given D-galactose. Results: At the end of treatment, pro-inflammatory markers includin...

In distributed Exascale computing system, due to the possibility of occurrence of a dynamic and interactive nature in execution time, it is possible. That the chosen destination computing node affected with dynamic and interactive nature so cannot be considered as a destination in process migration. This paper, by changing management approach in process migration. Consider process as an abstract element on the target computing node and calculates the impact of the factors the parameters affecting the process. Considering the above factors make process migration manager able to create sets of computational node that can be considered as destination computing node. In the event of a dynamic and interactive nature, in each element of the set, the process migration management, consider the effects of the factors affecting the activity of the process management and then re-weighs the computing element which make the above set. Using this mechanism allow the process migration management in case of dynamic and interactive nature occurrence in destination able to decide about changing on global activity execution so it is not necessary to recall load balancer manager in order to choose destination computing node. These subject louds to decrease execution time of process migration activity in distributed Exascale computing system.

This research provides some of the first empirical evidence of the use of management accounting and control practices in a lean manufacturing environment. It appears that as the implementation of a lean manufacturing strategy intensifies, the organization simplifies its internal accounting reporting system, eliminates inventory tracking and overhead allocation, and increases its use of value stream costing. We also find that the presence of top management support for change in production strategies motivates firms to the extent of lean manufacturing increases. In sum our study contributes to the accounting literature by providing insights on the working of package of management accounting and control practices in a lean manufacturing environment looks like and help keep our research relevant.

Islamic Morality an Integral Part of Modern Accounting

The reason of this problem has always been discussed. This paper studies the importance of Islamic ethics in accounting science. Unpleasant events and deviations in this profession have caused this problem to be addressed more than ever. Several reasons have contributed in this problem including different ways of failure, lack of complete rules and regulations with minimum errors and/or personal material and spiritual reasons, etc. One of the most important reasons is the lack of any ethical sensitivity. Although the ethics in accounting is not a new subject, it is only instructed in a few universities as a course. Considering unprofessional behaviors in traditional accounting, it is clear that ethics has been isolated as of its instruction. Ethics in Islam and Islamic accounting is considered among the major and primary princ...
