With the ever-increasing demand for blood resources worldwide, there is a great need to ensure a safe and adequate supply of blood products, and recruiting and retaining blood donors remains one of the primary challenges for blood transfusion agencies. The main objective of this research is to investigate the future development of blood donation culture in Iranian society, emphasizing the the role of social capital. This research is classified as applied in purpose and employs a mixed-methods approach. The statistical population comprises 10 experts of the blood transfusion organization. Purposive sampling method was used to select participants. Fuzzy Delphi and Micmac analysis were used for data analysis. The findings indicate that social capital is the most influential factor in blood donation. Moreover, among the various factors, philanthropy and public education were identified as the top priorities for effectiveness. The results obtained from the effects analysis showed that social capital had the largest direct and indirect effects. Philanthropy and public education also received the highest scores for direct and indirect dependence among other criteria. To address the impending shortage of blood donors in the coming decades, the blood transfusion organization must maintain the number of donors at a level commensurate with social needs by creating a culture and training that promotes voluntary donation.

The aim of the current research was to present an optimal model for total productivity based on the combination of ownership and supervisory efficiency of independent managers of companies listed on the Tehran Stock Exchange. This research was a descriptive-deductive description in terms of its practical purpose and the method used. In order to analyze the data using the panel data method and to test the hypotheses, multiple linear regression tests were conducted in a sample consisting of 80 selected companies admitted to the Tehran Stock Exchange in the period of 1393-1400. In this research, the rate of return on equity and the ratio of book value to market value were used to measure the productivity index. The results of the estimation of the research models showed that when the variable rate of return on equity is considered as a productivity index, the composition of ownership has a significant negative effect on productivity. In fact, greater concentrated ownership in the institutional and major shareholders of the company causes a significant decrease in the productivity of companies; however, the increase in the number of non-commissioned members compared to the total number of board members as an indicator of the supervisory efficiency of independent directors does not have a significant effect on productivity. The effects of financial leverage and company size on the productivity of companies were found to be both negative and positive, that is, when the variable of the ratio of book value to market value is considered as a productivity index, ownership composition has a negative effect on productivity, but the effect of increasing the supervisory efficiency of independent managers on productivity was found to be significantly positive. As a result, reducing the concentration of managers’ ownership and increasing the number of non-commissioned board members can improve productivity.

Subject and Purpose of the Article: 

The purpose of the current research was to present an optimal model for improving the quality of the internal information environment of companies accepted in the Tehran Stock Exchange based on the management features of government and non-government owned companies with the help of a comparative analysis of the artificial neural network model with the regression method.This study is applied and the method used is descriptive ex post facto (causal). To test the research hypotheses, a sample of 72 public companies and 38 nongovernmental organizations was selected during the years 1388-1400.We used panel data method to analyze the data and to test the first hypothesis, used the mean comparison test of two societies and used multiple linear regression and multilevel perceptron neural networks to predict the quality of the internal information environment.

Comparison of these two criteria showed that in addition to the effect of the management features of public and private companies on improving the quality of the internal information environment, in hypothesis 1-2 and hypothesis 2-2, with a coefficient of explanation of 0.67 and 0.75, respectively, compared to the MLP neural network method With a value of R2 0.47 and 0.50, it is preferred, but in the third hypothesis,The results showed that the regression method is more accurate in estimating and explaining the quality of the internal information environment of companies due to the greater number of observations compared to neural networks in this research.

The purpose of this research was to investigate the mediating role of career path development in relation to reducing perceived organizational justice with the glass ceiling. This research was descriptive-causal in terms of nature and method, also was applied in terms of purpose and in terms of research directions, it was one of the basic researches and the research data was collected by the questionnaire tool. The statistical population of the research was made up of all the female education workers of Hashtgerd city, and were selected 316 people from the table of Gorjesi and Morgan by random sampling. We used confirmatory factor analysis to analyze the data and used path analysis of structural equations to calculate path coefficients with the help of Amos Graphics software estimates.Based on the results of the path analysis, respectively, the total effects of the reduction of perceived interactional justice and the reduction of perceived procedural justice, the development of the career path and the reduction of perceived distributive justice on the glass ceiling were significant and the aforementioned variables could explain only 20% of the changes in the dependent variable. It can be said that by comparing the beta coefficients: the glass ceiling is more affected by the reduction of perceived interactive justice and the reduction of perceived procedural justice.
