Super-tall towers have surfaced as a pragmatic remedy to meet the escalating requisites for both residential and commercial areas and to stimulate economic growth in the Middle East. In this unique regional context, optimizing spatial usage stands as a paramount consideration in the architectural design of skyscrapers. Despite the proliferation of super-tall towers, there exists a conspicuous dearth of comprehensive research pertaining to space efficiency in Middle Eastern skyscrapers. This study endeavors to bridge this substantial gap in the literature.

The research methodology utilized in this paper adopts a case study approach to accumulate data regarding super-tall towers in the Middle East, with a specific focus on investigating space efficiency. A total of 27 super-tall tower cases from the Middle East were encompassed within the analytical framework.

Key findings can be succinctly summarized as follows: (1) average space efficiency was 75.5%, with values fluctuating between a minimum of 63% and a maximum of 84%; (2) average ratio of the core area to the gross floor area (GFA) registered 21.3%, encompassing a spectrum ranging from 11% to 36%; (3) predominantly, Middle Eastern skyscrapers exhibited a prismatic architectural form coupled with a central core typology. This architectural configuration mostly catered to residential and mixed-use functions; (4) the combination of concrete and outrigger frame systems was the most frequently utilized; (5) as the height of the tower increased, space efficiency tended to experience a gradual decline and (6) no significant discernible disparities were detected in the impact of diverse load-bearing systems and architectural forms on space efficiency.

Despite the proliferation of super-tall towers, there exists a conspicuous dearth of comprehensive research pertaining to space efficiency in Middle Eastern skyscrapers. This study endeavors to bridge this substantial gap in the literature.

The purpose of this paper is to study and specify to what extent Iran will succeed in being a regional hegemon. The paper is devoted to clarification of the constitutive elements for regional hegemony. These elements will be related to an actor’s perception of its role and regional perception, and how these hegemons exert power, do these work for the public good in the region (provision) and how this regional power projects power and exerts power to influence others’ preferences and values without reference to violence (projection). For the Middle East, Iran emerged as a key player in most regional conflicts and it tried to increase its sphere of influence as a regional hegemon. Therefore the question here would be: To what extend could Iran succeed in being a regional hegemon and what are the circumstances that could enhance or constrain this Iranian ambition? So the aim of the paper is to look at three dimensions in general and see whether Iran makes a plausible candidate for regional hegemony. The paper outlines the essential traits of a regional hegemon, and the main elements that constitute a regional hegemony such as perception, provision and projection, and then analyze how Iran follows those elements by analyzing internal perceptions of the Iranian elite about Iranian regional role, regional acceptance, provision of public good, projection and finally impact of the relation with external great powers. Through analyzing its regional strategy in Syria and Iraq since 2003, the year of invasion of Iraq, since ever a political vacuum was created, that enabled Iran to extend its regional influence, after the fall of its historical regional rival, Saddam Hussein baathi regime.

The study adopts an analytical framework of analyzing a regional hegemony strategy which is approached by Miriam Prys in her study “Hegemony, domination, detachment: differences in regional powerhood” to study and analyze Iran’s regional behavior as one of regional power that is seeking regional hegemony. This analytical framework is one of the most significant analytical tools that interests in the study of the behavior of regional power and identify the constitutive dimensions for regional hegemony such as self-perception, regional perception, provision and power projection.

The study concludes that there are obstacles completely in front of achieving the Iranian quest to regional hegemony over the Middle East. These are the continuing US involvement in the Middle East and the consequent tense relationship between Iran and the USA. It is most unlikely that Iran will be hegemonic state over the Middle East as long as there are refusal and resistance from other regional states for Iranian regional role; as each of regional powers has tools to contain the influence of the other. The Iranian regional behavior that is sectarianism-based, whether to protect Shiite shrines and holy places or to protect Shiites in the region, such policies deepen the ideological and sectarian conflicts. It also has not provided an attractive cultural model for the peoples of the region.

This paper enhances the deep analysis of the Middle East dynamics through the prospective of regional power. Also, the paper focuses on the analysis of the relation between great power and aspiring regional power and the impact on its strategies.

This study enhances the understanding of how Iranian decision-makers perceive their regional Iranian and the threats. Moreover, the tools that Iran uses its hard power and ideational one to create regional followers and change its allies’ normative and value systems to come in line with its national interests. Moreover, the study tries to measure the actual Iranian influence, its weakness and strength so that the Arab states and the West could behave in a fruitful way.

In the final analysis, the paper offers an insight into the regional behavior and the importance of external power in regional dynamics and to what extent the regional hegemon is applicable to Iran.

Effective business and investment climate can lead to a higher rate of investment, profits and improved productivity, through the creation of an institutional environment, where the state provides high-quality public goods. This study aims to explore the impact of the business–investment climate on firm performance in a sample of six countries in the Middle East and North Africa (MENA) region and Turkey. Furthermore, we extend our analysis to explore the impact of business–investment climate on the resource misallocation in Egypt and Turkey.

The study used fixed effects models to investigate the relationship between the business and investment climate, expressed by the obstacles in state–business relations- and the firm performance, which is measured by the firm's value-added, the labour productivity and the total factor productivity To reduce the endogeneity coming from possible reverse causality and the perceptions about the business climate, an instrumental variables (IV) approach applying the two-stage least squares (2SLS) method was followed. The empirical analysis relies on data derived from the World Bank Enterprise Surveys.

Based on estimates, the obstacles in business climate may reduce the firm performance measures by 15–40%. These findings indicate the importance of quality in the business climate and how the improvement in its efficiency can have a very considerable positive impact on firms' performance and thus on the overall economic growth of a country.

This is the first study exploring the impact of business–investment climate on various measures of the firm performance and the resource misallocation in a large sample of countries in the MENA region.

The Asian banking system has been appreciated with many distinct qualities including consistent in profitability. Many studies have examined the profitability of Asian banking sector from diverse perspectives. However, studies on bank profitability in connection to the capital structure, operating efficiency and non-interest income are only a few. This study investigates the influence of capital structure as estimated by leverage ratio and long-term debt, operating efficiency and non-interest income on the profitability of the banking industry in 28 countries of Asia.

This paper utilizes fixed effect regression model by involving panel data with sample of 492 banks from 28 countries of Asia for the time span of 15 years from 2004 to 2018.

The results confirm that an increase in total debt ratio increases the profit margin of the bank as supported by the agency cost theory, suggesting that the debt financing increases the profitability of the firm. In addition, the findings reveal that lowering the operating expenses and managing of costs effectively can boost the profitability of bank. Furthermore, non-interest income plays a vital role when the interest rates are lower. Hence the study suggests that a careful investment in this sector can generate income as well as increase the profit margin of the banking arena.

The paper examines the profitability of bank by including impact of leverage ratio and long-term debt as a measure of capital structure along with the influence of operational efficiency and non-interest income which contributes to the understanding of the existing literature.

The study aims to examine the geoeconomic significance of the Gulf Cooperation Council (GCC) countries to China’s global geopolitical ends. In this vein, the paper also seeks to explore the interplay between China’s grand geoeconomic strategy and China’s geopolitical ends from a realist perspective.

The study uses the realism theory to explore the interplay between China’s geoeconomic presence in the GCC countries and its geopolitical global ends.

The study concludes that China under President Xi Jinping has geopolitical ends, and they are the regional and global leadership. To achieve them, President Xi has formulated a grand geoeconomic strategy consisting of four strategies: going out strategy, periphery strategy, Belt and Road Initiative (BRI) and Asian Infrastructure Investment Bank. These strategies will maximize China’s economic power and presence around the world. From a realist perspective, this presence and its evolving consequences such as the balance of dependence will enable China to achieve its geopolitical ends. In this vein, China’s geoeconomic strategy in the GCC countries has largely maximized China’s economic presence in the Gulf. This presence highly serving China’s geopolitical global ends for two reasons: the economic weight of the GCC countries and their strategic location within BRI.

The study can prove the realistic dimension of geoeconomics in the neoliberal era on the application to China’s geoeconomic strategy.
