The green supply chain management model is for environmental protection, which companies could use to reduce negative environmental impacts and achieve the optimal use of resources and energy. The study is an attempt to identify and develop a similar model for the petrochemical industry of Iran’s Fars province using Grounded Theory as a qualitative data technique and the DEMATEL method to test its effectiveness and efficiency. The data collection was based on documents as well as interviews with 20 experts selected through snowball sampling. To analyze the qualitative data, three stages of open, axial and selective coding were used. Criteria were also prioritized using the DEMATEL method and questionnaire. The results indicated the extraction of 21 axial and 90 open coding, which were placed in the form of a paradigm model. Then, using pairwise comparisons in the said method, and the final ranking of selected criteria of green supply chain, showed that the central process design, customers and other external institutions, green innovation, environmental management approaches, human resource management, environmental performance improvement, management and optimization of energy consumption (with values greater than the threshold) have a higher degree of importance (weight).

Professional identity refers to a process that answers the question "who am I" during One has been studying for years at university. The PhD is the latest stage in the development of this kind of identity that has a great bearing on the career path of individuals. The present article attempts to test the theoretical model of the PhD students' professional identity development in Iran's social sciences. The Grounded Theory of Vedadhir and Others (2017) have been operationalized and the questionnaire has been tested with participation of 191 PhD students of social sciences. Quantitative findings confirm the theatrical propositions obtained from the basic theory model. As can be seen in the above equation, Regression results show that in general, the structure of higher education, the external conditions of the social sciences, the psychological traits of PhD students of social sciences, as well as financial conditions and scientific socialization can change the dependent variable of the professional identity of the PhD degree of social sciences among respondents Better than the rest of the independent variables. The statistical results indicate that the role of external and structural factors is important.
