INTRODUCTION: The structure of the urban platform of Tehran and its physical characteristics depends on the inherent conditions and environmental thresholds in relation to changes. This study aimed to determine the natural landscapes of Tehran by two phenomena of earthquake and flood that posed the highest risk in different periods of this city. Therefore, the natural perspective of Tehran is divided into three perspectives of north, central, and south regarding the inherent features and evolutionary process. METHODS: The relationship between the perspective of Tehran based on the form and geomorphological processes and the evaluation of earthquake and flood hazards have been observed in four stages, which included data collection, data processing, calculation of indicators, and analysis of findings. The studied area was divided into three northern, central, and south urban landscapes to determine the resistance thresholds of the city according to the characteristics of topography, physiography, geology, the results of field studies and satellite images, aerial photographs, as well as paleogeomorphological research in Tehran. FINDINGS: According to the zoning map of Tehran based on the earthquake phenomenon in three perspectives of north, center, and south, the highest distribution of non-resistance is observed in the northern and southern areas of the city. Northeast, southwest, and semi-western regions have the highest urban resilience to earthquakes. Moreover, regarding the zoning of Tehran based on the flood phenomenon in the three perspectives of north, center, and south, the highest distribution of non-resilience has been observed in the northern regions of the city. Northeast, southwest, and west of Tehran have the highest urban flood resilience. CONCLUSION: Based on the results of the present study, in order to increase resilience against the risks of earthquakes and floods, the city of Tehran should be studied not in just one perspective but in different perspectives.

Purpose : The present study aimed to present an interpretive structural model based on DEMATEL for the Entrepreneur University among top universities in the northern region of Iran. Methodology : This study was applied in terms of objective and combined (qualitative and quantitative) in terms of implementation method. The research population in the qualitative section were documents and texts of the Entrepreneurship University and experts in this field that 35 documents and texts and 30 experts were selected as samples according to the principle of theoretical saturation by purposive sampling method. The research population in the quantitative section consisted of the same 30 experts who rated the components. The research tools included text review, semi-structured interview, and 77-item researcher-made questionnaire that their psychometric indices were confirmed. Data were analyzed by Delphi methods and interpretive structural modeling based on DEMATEL in SPSS-23 and LISREL. Findings: The results showed that the Entrepreneurship University included 77 concepts, 24 sub-components in 6 main components. So that among the 6 main components, three components of infrastructure (with four sub-components), management (with five sub-components), and communication with the population (with four sub-components) were identified as effective variables, and three components of services (with three sub-components), knowledge-based entrepreneurship (with five sub-components) and output and outcome (with three sub-components) were identified as affected variables. The results of DEMATEL-based interpretive structural modeling showed that in the first level with 10 components, the component of commercialization of knowledge and research and revenue generation from advanced technology, in the second level with 7 components, the component of entrepreneurial research, R&D, and dissemination of academic results, in the third level with 14 components, the component of entrepreneurial research, R&D and dissemination of academic results, and in the fourth level with 1 component, the core component of strong leadership and change in structural and managerial dimensions were at a higher level. Conclusion : According to the results of the present study, planners and higher education professionals can take advantage of the results of this study and plan for the improvement and growth of the Entrepreneur University through the effective components identified in it.
