The purpose of the research Decline of Auditors' Financial Bias in Decision making by Professionalism in Auditing: Rough Set Analysis. The research approach is of inductive-deductive type in terms of the data collection meth-od, because it was first determined based on the content analysis of the com-ponents and propositions related to the professional characteristics, then it was tried to confirm or delete the propositions based on the Delphi analysis. This research by participating 14 individuals of the audit partners with the academic degrees over a one-year period, 2018-2019. The results According to the formation of decision making matrix, the results showed that both propositions, the perceptual error of failure to separate the context from con-tent as the Halo bias and the perceptual error of the experience of fraud de-tection in the financial statement as memory bias were determined as the most influential perceptual errors in the audit profession in Iran. In addition, according to gray vikor theory analysis, it was found that the component of the audit's professional maturity was selected as the most important priority and the most effective feature for reducing the audit perceptual bias.

Chief executive officers (CEO), as the central pillar directing companies at the capital market level, plays a critical role in making investment decisions to de-crease agency costs and maximize shareholders’ wealth; however, their psycho-logical attitudes and perceptions lead to different investment functions of these companies in a competitive market. Accordingly, this study aimed to detect the propositional arrays of the investment functions using Q analysis in order to identify the CEOs’ mental typology in distinguishing investment functions. The present study was carried out with the participation of 13 CEOs from Tehran Stock Exchange companies during a one-year period (2018-2019). The study encompassed two different phases. In the first phase, content analysis was used to identify the phrase Q of the CEOs’ investment functions. In the second phase, Q analysis was adopted to typify the CEOs’ investment functions, which was based on the subjective cognition of the target population and contributed to the development of the approaches in line with the research objectives. The results confirmed the existence of three mental patterns in the CEOs regarding the in-vestment functions in the capital market. These mental patterns were ‘investment function in stock market indices’ as the first mental pattern, ‘investment function in risk control’ as the second mental pattern, ‘strategic investment function’ as the third mental pat-tern. The study results revealed different types of investment functions among the CEOs’ of stock exchange companies and thus contributed to the development of financial theories from the perspective of CEOs’ cognition.

The efforts of the developers of capital market laws and regulations over the past years have been aimed at increasing the level of information transparency to create more symmetry between companies and shareholders so that they can be more attractive to investors to invest in the stock market. But given the interplay of individual characteristics of corporate decision-makers with the interests of shareholders and investors, it seems that focusing on behavioral functions in the area of promoting managerial ability can more effectively lead to increased protection of shareholder interests. The purpose of this study is to investigate the effect of management ability on the protection of investors based on the development of the theory of the devil's advocate. Therefore, the present study, using the structural equation modeling approach and partial least squares analysis (PLS), while fitting the model's desirability, examined the impact of management ability on protecting investors. In this study, in order to measure the in-field variable, ie protection of shareholders' interests, a researcher-made questionnaire was created through meta-analysis with the participation of 15 research experts. Then the criterion of Demirjan et al (2013) was used to measure managerial ability as an exogenous variable in partial least squares analysis. The researcher-made questionnaire was sent to 142 CEOs of companies listed on the Tehran Stock Exchange, and finally, after many follow-ups, 105 questionnaires were completed and returned and used as a final sample for analysis. After ensuring the acceptable fit of the measurement and structural models of the research, according to the theory of the devil's advocate, the results showed that the ability of management has a positive and significant effect on protecting the investors. Managerial ability, as one of the specialized decision-making capacities, puts the company on the path of effective interaction with stakeholders and provides the ground for investors to Protect in companies' priorities to gain their trust.

The purpose of this study is to analyze the most effective basis for assessing the intellectual capital maturity based on the themes of the ambidextrous learning link. In terms of purpose, this research is part of developmental research. Because of the lack of a basis for assessing the intellectual capital maturity under ambidextrous learning in previous research, based on meta-synthesis in the first step, an attempt was made to identify components as the analytical basis of the research and propositions as reference variables. Then, in order to explain the identified components and propositions, in a small part, intuitive fuzzy sets (IFSs) was used to determine the most effective basis for evaluating the intellectual capital maturity based on the themes of the ambidextrous learning link. In this study, the target population consisted of two parts: qualitative and quantitative. In the qualitative section, with the help of 16 management specialists and experts, an attempt was made at the university level to identify research components and propositions in the form of score forms. In the small section, 50 managers, officials and experts at various levels of knowledge-based companies participated. The results showed that the proposition of strategic tendencies in learning is considered as the most influential themes of the ambidextrous learning link in the studied companies, which strengthens the sustainability of knowledge creation as an effective component in the intellectual capital maturity.

Since the auditing profession is a process engaged in judgment activities, knowing the reasoning concepts to achieve a level of rationale in audit judgment is the theoretical and fundamental concept in this profession. In this regard, tactfulness is one of the decision-making components in an auditor's judgment that assigns a level of reasoning for making an intellectual decision and promotes the level of judgment quality in auditing. Accordingly, the purpose of this research is Auditors’ Wise Tactfulness in Professional Judgments by Total Interpretive Structural Modeling (TISM). The mixed-methods approach was used for the research in which, in the qualitative part, two experts population as panel members, and, in the quantitative part, 30 independent auditors as the statistical population participated. In the qualitative part, the meta-analysis approach was used to identify the themes related to wise tactfulness in professional judgment, and then, the basic themes selected were examined based on two criteria, concordance coefficient and average, in three rounds reciprocally until theoretical saturation was met. At this point, 14 themes were accepted among 20 basic themes. In the quantitative part, the themes accepted were coded first and then were distributed among the respective population, based on a matrix questionnaire, to identify the most effective trait of auditor's wise tactfulness in professional judgment using the Total Interpretive Structural Modeling approach. According to the results, the theme adherence to the principles of professional ethics as a basic theme of professional thinking was selected as the most influential trait of wise tactfulness.

Managers are responsible for providing financial statements and they might try to make a good picture of their firm's conditions. Therefore, they try to delay the disclosure of bad news and release the good news as soon as possible. The ten-dency of managers toward hiding bad news increases the stock price crash risk. The protection of investor is one of the factors that can prevent from falling stock price, because it restricts the managers and majority shareholders in frauding and hiding bad news. Thus, the main purpose of the present research is to study the effect of investor protection on future stock price crash risk. In this research, 89 companies from listed companies in Tehran Stock Exchange during 2011-2017 were tested. The results obtained from the research's hypothesis test showed that protecting the rights of investors has a negative effect on the stock price crash risk. In fact it can be concluded that with the increase of the investor protection, the firms are obligated to disclose the high-quality accounting information and present more transparent financial reporting, as a result, the information asym-metry will be reduced and by creating a flow of information between the manag-ers and the investors and thus failure to accumulate bad news in the company, the risk of the stock price crash will be also reduced.
