Currently, the global community is on the threshold of a transition from fossil fuels as a result of transformations such as climate change, entailing the strict implementation of carbon setoff policies and quick progress in green technologies. A transition to clean, low-carbon energies will not only disrupt the global energy system, it will also impact the global economy and political dynamism within and without all states. Based on these transformations, the present article asks the question of how the energy transition will impact the geopolitical future of the global oil economy. The authors hypothesize the following in answer to this question: Given the superior, more advanced position of economic powers such as China and the US in clean energy technologies, we are likely to witness the weakening of traditional oil powers in a post-carbon world, such as the Middle East and North African countries (MENA) and Russia; in contrast, the balance of power will tilt heavily towards current energy consumers. Technology-savvy countries have the knowledge to reproduce and stabilize their power in the global economy. The traditional countries of the energy sector, however, face shortfalls in their infrastructure and modern technologies and will lose their geopolitical position to a large extent.

Although the prevalence of COVID-19 pandemic and the worldwide periodic lockdowns, and travel restrictions have heavily damaged tourism destinations, however some theorists believe that the channels and intensity of adverse effects of COVID-19 are not even in different tourism destinations and it may depend on the tourism form that the destination is endowed with. The purpose of this research is to fulfill a comparative survey between two different tourism destinations that enjoy two different tourism forms, including pleasure tourism (Ganjnameh region) and commercial based tourism (Lalejin region) in Iran and try to explore the different complex aspects of COVID-19 effects on tourism industry and compare sustainability of both tourism forms. In order that, we apply Grounded Theory (GT) model and relay on qualitative data gathered by face-to-face interviews with 40 participants who are engaged in tourism related businesses in sample destinations. In according to the results, this study critically derives 4 different aspects of complexity of the situation arisen from corona virus pandemic on tourism sector in Ganjnameh and Lalejin including: resilience strategies and sustainability, change in tourist behavior, change in the tourism industry, and aggravating factors. In addition, the results showed that changes to tourism as a result of COVID-19 is complex and uneven in two different tourist destinations. Moreover, we realized that the economic statues of Ganjnameh region which is widely depend on pleasure tourism is more vulnerable to unexpected tourism crises compared to the Lalegin region, where the economics of a big bulk of habitants depends on commercial tourisms and handicrafts. Therefore, the commercial based touristic destinations looks more resilient and sustainable in comparison to pleasure tourism formed destinations. This study released valuable information about current statues and future concerns about tourism industry and offers suitable policy implications to cope with COVID-19 effects during and after Corona crisis.

With the advent and growth of Islamic banking, various researches have been performed to analyze the performance and mechanisms of regulatory rules of this industry. Due to the special role of banks in the economic systems of countries and the world, significant regulatory and control rules were used. In the meantime, the commitment to implement the rules of the Basel II Capital Accord as the most important international agreement to ensure banking health is of particular importance, and among all the issues raised in this agreement, compliance with the minimum capital adequacy has been considered by many researches. One of the most important questions in this area is whether the Basel method of calculation and the minimum rate (8%) is appropriate for the Islamic banking system? To answer this question, this study has calculated the capital adequacy ratio for Islamic banks of Iran and by modeling its effect on the bank’ profit efficiency, as the most important incentive indicator for banks, has estimated an optimal rate these banks.
