The value of a company is important to shareholders, investors, managers, creditors, and other stakeholders in their assessment of the company's future, its impact on the estimation of investment risk and returns, and stock prices. Therefore, examining the factors affecting a company's value is crucial. Intellectual capital, as a determinant in creating competitive advantage and value, plays a special role and is considered as an intangible asset of companies. Theoretical background and empirical evidence suggest that intellectual capital has a direct impact on a company's value and performance. Moreover, the need for corporate governance arises from the potential conflict of interest between individuals within the company's structure, which can affect its value. As banks’ shares play an important role in the Tehran Stock Exchange, we examine the impact of intellectual capital and good corporate governance on bank value, with the mediating effect of financial performance. The statistical population of this study includes 17 banks listed on the Tehran Stock Exchange over the period from 2017 to 2021. The results indicated that intellectual capital has a significant effect, while corporate governance does not have a significant effect on bank value. Additionally, the mediating effect of financial performance on the relationship between intellectual capital and bank value is accepted based on the Baron and Kenny method for mediation. The findings also show that the mediating effect of financial performance on the relationship between good corporate governance and bank value is confirmed according to the Zhao et al. procedure. Moreover, the results indicated that adding another independent variable relatively increases the explanatory power of the model.

This study investigates a multi-objective minimum cost flow with probabilistic objective function coefficients (Poss-MOMCF). Under using the α−cut set of the possibilistic variables, the Poss-MOMCF problem is converted into the corresponding (α-MOMCF) and hence into the (P-MOMCF) problem. A necessary and sufficient condition for investigating the α−possibly optimal solution is established. A fuzzy goal programming approach is applied to obtain the α−parametric optimal compromise solution. The stability set of the first kid under the concept of α−possiblyoptimal solution is characterized and analyzed without differentiability. Finally, a numerical example is given in the sake of the paper to clarify the methodology

Timely audit reports are essential for stakeholders in the healthcare sector to make informed decisions about the financial health of organizations. However, there is limited research on the factors influencing audit report timeliness in this sector.

This study will utilize a quantitative research design to analyze the determinants of audit report timeliness in the healthcare sector. Data on board size, composition, audit fee, and audit timeliness will be collected from a sample of healthcare organizations. Preliminary findings suggest that board size and composition significantly impact audit report timeliness in the healthcare sector. Organizations with larger boards and more independent directors tend to have timelier audit reports. Additionally, higher audit fees are associated with faster audit report timeliness. However, the relationship between audit timeliness and audit report timeliness is inconclusive and requires further investigation.
