Today, the construction industry has a significant share of the economy and is considered as a leading and employment-generating industry. Due to various and sometimes risky activities during construction, there is a possibility of risks and personal and financial injuries, the control of which can be very effective in the success of the project. In the present study, a model for evaluating the safety risks of construction projects has been presented and new powerful tools such as fuzzy expert system improved with genetic algorithm have been used. Therefore, at first, the main factors influencing the safety of construction projects were identified by studying the literature and consulting with experts. Then, a questionnaire was provided to the experts to obtain their views and assess the severity of the risk effect and the probability of the occurrence of each risk. Then, based on the experts’ views, an expert system was obtained to assess the risks, which instead of using zero and one logic, governing expert systems, fuzzy logic was used. In the proposed model, to improve the performance of the fuzzy expert system, the genetic algorithm was employed as an optimizer. The research results indicated the optimal performance of the proposed model in assessing the safety risks of construction projects, so that the error rate of the model was acceptable. The model can also provide an effective tool for project managers in assessing and refining the safety situation in the construction site.

Transformational leadership, workplace spirituality and employee creativity are important issues in organizational management. The purpose of this study was to investigate the impact of transformational leadership on employee creativity with the mediating role of workplace spirituality. The present applied study was a descriptive-correlational one, conducted with a sample of 135 prevention police managers of Qom Disciplinary Command. Stratified simple random sampling method was used to select the sample. To collect the data, three standard questionnaires, including Bass et al. (2003), Torrance (1963) and Milliman et al. (2003) and to analyze the collected data, correlation coefficient tests, confirmatory factor analysis and structural equation modeling were employed. The reliability of the instruments was checked using Cronbach's alpha and the validity of all components of the questionnaire was verified first through the formal method and then the confirmatory factor analysis. The findings showed that transformational leadership, has a positive direct effect on workplace spirituality (0.61) and on employee creativity (0.73) at a significant level of 0.001.

The purpose of this study was to design an organizational ambidexterity model in the branches of Tejarat Bank in Isfahan, identifying important indicators. The research method was a sequential combination of exploratory case study and survey. Grounded theory and Lisrel software were used to confirm the identified organizational ambidexterity model and test the hypotheses. Based on the initial findings of the grounded theory technique, 74 indicators remained after the initial screening and removal of duplicate and redundant codes. These indicators were introduced as the input data of fuzzy Delphi technique and finally 18 indicators were considered to continue the process and present the main and sub-themes. The organizational ambidexterity model and its identified importance for generalization to the whole complex were confirmed by the structural equation approach (exploratory factor analysis). Human resource indicators of the two-dimensional organizational model, which mainly refers to the organizational and individual cultures, show the influential role of the internal characteristics of individuals and organizations in the implementation of a new concept. Among strategic indicators the emphasis was on the existence of a flexible structure to implement dual power. In terms of social capital, a significant point was the high priority of the index of reviewing social processes and components in the total indicators of the ambidextrous organization. This means that in the early stages of implementing dual power, it is necessary to review the processes and equipment to discover exploitation and exploration opportunities, plan to pursue these opportunities simultaneously, and develop an ambidextrous model in different parts of the bank.

The purpose of this study was interpretive structural modeling of the factors affecting supply chain optimization in the electricity industry. In this study, using a mixed method, a qualitative-quantitative approach was employed to model and verify the factors affecting supply chain optimization. To this end, through content analysis and thematic analysis using Novo software to form thematic networks, a qualitative model of factors influencing supply chain optimality was designed. In order to formulate a basic pattern of the factors affecting supply chain optimality, 23 experts in the electricity industry were selected through purposeful sampling method. In the quantitative section of the study, interpretive structural modeling (ISM) approach and MICMAC analysis were used. The results showed that the initial framework of supply chain optimality model has six dimensions including supply chain performance, supply chain management, supply chain risk management, supply chain quality management, production and operation, and supply chain stability. In the ISM graph, the variables were categorized at different levels, in which the "agency" and "strategy" factors were the highest and "customer satisfaction" was the lowest factor. After MICMAC analysis, the variables were categorized in three groups of independent variables with 11 variables, with four variables and dependent variables with 10 variables. No variables were included in the PA.
