The purpose of this study is a new understanding behaviour and net cash flow forecasting. The data of this research contains the daily trial balance for one year, which has been received from 48 bank branches. For this purpose, the optimal model out of 4 models; Geometric Brownie, Arithmetic Brownie, Vasicek and Modified Square Root at three levels of microscopic, mesoscopic and macroscopic have been investigated and the Geometric Brownie model has been approved as the optimal model in microscopic level . The results show that Geometric Brownian Motion model can simulate the net cash flow highly accurate in accordance with the criteria of mean absolute percentage error. also forecasting net cash flow for each under study time series has been done in various forecasting horizons involved 7, 14, 21, 30, 60, 90 and 180 day time period accordance with the criteria of mean absolute percentage error. Also The other results obtained from this study is that according to 8 different prediction accuracy criteria, By increasing the forecast hori-zon, ability of the GBM model in simulation and forecasting the net cash flow de-creases.

The purpose of this study is to perform a meta-analysis of the relationship between auditor characteristics and profit quality. In order to integrate the results of different researches and identify the factors that modulate the relationships between auditor characteristics and profit quality, in this research we will use meta-analysis methodology which is one of the quantitative statistical methods. In order to implement the meta-analysis method, they were identified and collected from the websites of foreign journals (articles published in the period 2005 to 2020) and the Internet site of domestic scientific research journals (articles published during the years 2006 to 2021) as a statistical population of the research. Systematic removal has finally analyzed 50 studies; The results of studies conducted in the period and around this relationship indicate that most of these studies are heterogeneous. In order to identify the cause of this heterogeneity, by dividing the research based on different criteria for measuring profit quality and auditor characteristics and calculating intra-group chi-square statistics, we found that these different measurement criteria used in research are one of the factors of contradiction in the results. There have been researches. In the following study, it was observed that there is no significant relationship between auditor characteristics with profit smoothing and timely profit and also between non-audit services provided by the auditor and profit quality, while in contrast, there is no significant relationship between auditor characteristics and quality of accruals; Profit stability; There is the ability to predict profit and conservatism.

Traditional approaches applied in supply chain management consider only the physical logistic operations and ignore the financial aspects of the chain. In this study, a mathematical model has been developed to address the supply chain network design problem with a value-based management approach. This model integrates both operations and financial aspects to maximize the value created and measured by shareholder value analysis (SVA) as an objective function. The results attributed to the developed model and the basic model are compared. The results indicate that creating more value for the company and its shareholders is achievable with appropriate financial decisions. To validate and show the applicability of the proposed model, it was solved by GAMS software with data provided by literature. Finally, sensitivity analyses on financial parameters were performed to evaluate the results. The results clearly reveal the improvement of using the new approach and convince managers to take advantage of the proposed approach.

Auditors' personality traits have a significant effect on the motivation of their financial behavior. In fact, the personal and personality traits of auditors that can be influenced by the environment play an important role in motivating individuals to engage in financially professional behaviors. Audit team norms are one of the factors in the audit firm environment that affect the auditor's behavior. In this study, the effect of auditing team norms and auditors' personality types on auditor objectivity was investigated. The Entropy technique is used to examine the importance of the norms of the audit team and the personality components of the peers, and based on the results and using the TOPSIS method, these factors affecting the objectivity of financial auditors are ranked. The statistical population of this study includes all professional auditors working in the auditing organization and private auditing institutions, members of the Iranian Society of Certified Public Accountants in 2020, including 242 members. The results showed that extroverted and responsible personality types have a positive and significant effect on auditors' objectivity. The results also showed that the norms of the audit team have a positive and significant effect on the objectivity of auditors.

Proving helpful in an efficient management of cash in order to reach optimal cash and clearly explain relevant optimization policies, this study examined the adjustment speed of cash holding using asymmetric models. The sample consisted of 117 firms listed in Tehran Stock Exchange and their financial details over the 2009-2018 period. Once the optimal level for cash holding was identified, asymmetric models such as the dummy variable approach, the quadratic model, and the threshold regression model were employed to test the adjustment speed of cash holding. The results revealed that cash-rich firms are moving toward optimal cash at a greater speed than cash-poor firms. In addition, the results from the quadratic model showed a non-linear, skewing effect of the cash holding adjustment speed in terms of the different cash levels. Therefore, there is an optimal level of cash holding that enables firms to deviate from the cash target. Should firms fall outside the optimal cash range, cash adjustment will occur at a greater speed, and it will be both partial and asymmetric.

In the field of corporate tax behavior, corporate governance mechanisms are effective for shaping and monitoring the behavior of managers. The board, which is responsible for allocating resources, improving performance and increasing shareholder wealth, plays a central role in choosing a tax management strategy. Hence, companies with different governance structures may adopt different types of tax management. Therefore, it can be argued that corporate governance mechanisms can affect corporate tax activities. In order to achieve the weight of the identified criteria, the network analysis process method was used. The purpose of this method was to structure the decision-making process, according to a scenario affected by multiple independent factors. In this method, there can be a relationship between all levels, while in the method of hierarchical analysis process, this relationship could only be from high levels to low levels. The method of the network analysis process, such as the hierarchical analysis process, calculates the inconsistency of all judgments by the conformity rate, and the calculated inconsistency rate must be less than 10%. The compatibility coefficient of the final matrix shows the validity of the questionnaire. In order to analyze the data, Super Decision 1.6.0 software developed by Thomas L. Saati, the inventor of this method, as well as MS Excel 2019 software were used. There is considerable evidence that increasing tax requirements can increase tax compliance, but typically some types of tax offenses are used as a tool to control the phenomenon of tax default.

FinTech is the solution that strengthens the way of financial communication and if we apply this technology, it will provide us with new methods of performing smarter, more agile and wider financial services. The purpose of this study is to investigate and analyze the factors affecting the implementation of FinTech in Iran's banking industry using structural equation modeling to provide comprehensive solutions of removing barriers and development of this industry in the Iranian banking industry by fully understanding the current situation. The present article is of descriptive-analytical type and data collection has been done through library studies and questionnaires. The statistical sample of the study was 12147 personnel working in Iran's banks in 1400. Due to the size of the population, Cochran’s method and random sampling method were used to determine the sample size. To analyze and classify the extracted data, a questionnaire and a test of the main hypothesis and sub-hypotheses and structural equation modeling were used using smart PLS statistical software. The obtained results confirm the main hypothesis and the sub-hypotheses of the research. The results indicated that in the banking sector, there is a need for legalization and harmonization with upstream laws, as well as the need for infrastructure and tools that are very important in adopting strategies to implement FinTech in Iran's banking industry, in order to make transparency, reduce costs, provide high-speed services, and move towards a smart economy.

Adrienne Mayor’s The Poison King is a fascinating biography of Mithradates Eupator Dionysus, one of the most controversial monarchs of ancient history who has been especially neglected by scholars of Iranian history. This biography, like any other about ancient heroes, is full of tales, legends, stories, and historical narratives and its crafty author knows how to distinguish between fact and fiction. The book contains 15 chapters, in which, other than  the first, the remaining chapters are arranged based on Mithradates’ life, from his birth to his death.

Khalifeh Kandi village is located in the southeast of the Sahand mountain range and northwest of Hashtrud province. Investigation at these sites started in 2013 and continued until 2015. Obtained evidence included a variety of potteries, carved stones, and caves from the historical and Islamic eras. in this paper an attempt has been made to introduce and analyze cultural and historical founds. The result shows that most of the surveyed sites and places around Khalifeh Kandi, in terms of pottery types, belonged to the Islamic period and rarely, artifacts from the pre-Islamic period were observed. The settlements identified in the area under study are mostly located in w slopes by the river and shallow valleys, and only one of these archaeological sites was observed in flat and elevated lands. probably this site was used in certain seasons of the year. Glazed and simple pottery from the Islamic period and rough pottery that was produced in local workshops are among the artifacts observed in the surveyed sites.

Emphasis on the importance of social-political fabric and its effect on the urbanization and economic system that are aspects of urbanization life is one of the necessities during the Achaemenid Period. This study was conducted based on the deductive-inductive method. First, written sources (clay inscription of Persepolis and classic authors) have been used to achieve general information about the social-political fabric of Fars during Achaemenid Period then archeological evidence remained from the economic system of Achaemenid period in Central Fars was analyzed within this framework. No coin, including Shahi or so-called Satrapy, has been discovered from archaeological excavations in Iran, even. It seems that Achaemenid Empire had no plan for monetary economic development, and coin promotion and use in transactions despite its wide territory and regular discipline. On the contrary, it seems that Darius and his successors considered coin as a political instrument used to convey and show the message of the political and military power of the Achaemenid king at that ear not as a tool for the economic system. Therefore, studies focused on clay inscriptions of Persepolis and evaluated works of authors indicate that the sociopolitical fabric of Iranian society, especially Fars has been traditional and based on agriculture and husbandry during Achaemenid Era. As we know, the city was not shaped during the Achaemenid period despite the presence of urban structures, such as social sophistication, specialism, and the modern administrative system of the ear; therefore, coin use was not institutionalized in the economy of that era.
