Abstract
Purpose
More electric aircraft (MEA) is defined as the extensive usage of electric power in aircraft. The demand for electric power in new generation aircraft rises due to environmental and economic considerations. Hence, efficient and reliable starter/generators (SGs) are trending nowadays. The conventional main engine starting system and power generation system can be replaced with an individual SG. The constraints of the SG should be investigated to handle the aviation requirements. Even though the SG is basically an electric machine, it requires a multidisciplinary study consisting of electromagnetic, thermal and mechanical works to cope with aviation demands. This study aims to review conventional and new-generation aircraft SGs from the perspective of electric drive applications.
Design/methodology/approach
First of all, the importance of the MEA concept has been briefly explained. Also, the historical development and the need for higher electrical power in aircraft have been indicated quantitatively. Considering aviation requirements, the candidate electrical machines for aircraft SG have been determined by the method of scoring. Those machines are compared over 14 criteria, and the most predominant of them are specified as efficiency, power density, rotor thermal tolerance, high-speed capability and machine complexity. The features of the most suitable electrical machine are pointed out with data gathered from empirical studies. Finally, the trending technologies related to efficient SG design have been explained with numeric datasets.
Findings
The induction motor, switched reluctance motor and permanent magnet synchronous motor (PMSM) are selected as the candidate machines for SGs. It has been seen that the PMSM is the most preferable machine type due to its efficient operation in a wide range of constant power and speed. It is computationally proven that the using amorphous magnetic alloys in SG cores increases the machine efficiency more. Also, the benefits of high voltage direct current (HVDC) use in aircraft have been explained by a comparison of different aircraft power generation standards. It is concluded that the HVDC use in aircraft decreases total cable weight and increases aircraft operation efficiency. The thermal and mechanical tolerance of the SG is also vital. It has been stated that the liquid cooling techniques are suitable for SGs.
Originality/value
The demand for electrical power in new generation aircraft is increasing. The SG can be used effectively and efficiently instead of conventional systems. To define requirements, constraints and suggestions, this study investigates the SGs from the perspective of electric drive applications.

Abstract
Purpose
This paper aims to explore the prospects and the challenges of Islamic fintech in Indonesia. This study also proposes a comprehensive legal framework to encourage and accelerate the growth of the Islamic economy.
Design/methodology/approach
This study is the result of legal research with a statute approach and conceptual approach. The types of data used are legal materials consisting of primary legal materials and secondary legal materials. The technique of collecting legal materials is done by using library research techniques. The legal materials were analyzed using the legal norm method.
Findings
Indonesia is a country with the largest Muslim population in the world. However, the market size of Indonesia’s Islamic fintech is still below Saudi Arabia, Iran, United Arab Emirates (UAE) and Malaysia. Saudi Arabia’s Islamic fintech is the biggest market in the world, with $17.9bn worth of transactions in 2020 while Iran is at $9.2bn, UAE $3.7bn, Malaysia $3.0bn and Indonesia $2.9bn. This condition was due to various challenges in the Islamic fintech industry in Indonesia, including inadequate regulations; complicated permit procedures; misuse of fintech for financing terrorism; rampant occurrence of illegal fintech businesses; and consumer disputes in the fintech sector. These challenges require the construction of a comprehensive legal framework through the formation of an Act on Fintech.
Research limitations/implications
The focus of this research was limited to the problems occurring in the Islamic fintech sector in Indonesia as a country with the largest Muslim population in the world.
Practical implications
The results of this research can be used as recommendations for the formulation of comprehensive policies for the growth and development of Islamic fintech.
Social implications
Islamic fintech requires a comprehensive legal framework that functions to encourage the development of the Islamic fintech industry, digital economy growth and legal mitigation of various legal risks and misuse of fintech for financial crime and financing terrorism.
Originality/value
This paper proposes an original idea of creating a legal framework in a form of the Islamic Fintech Act. The Act should cover such legal substances as follows: Islamic compliance; an integrated one-stop permit procedure; division of authority, coordination and synergy among authorities; prevention and resolution of digital financial system crisis; criminal sanctions; and consumer dispute resolution mechanisms and alternative institution for fintech consumer dispute resolution.

Abstract
The current Industry 4.0 era is considered not only as a process that dominates technological developments but also as a process that influences the leadership styles. Management 4.0 is essential for businesses to find and apply the appropriate technologies in the age of Industry 4.0. The leadership styles that business managers will adopt in order to be successful in this process and to survive in an intensely competitive environment can play an important role. At this point, a significant problem arises: identifying leadership styles that will bring success. In this context, the primary purpose of this chapter is to explain the modern leadership styles that business managers can adopt or follow in the age of Industry 4.0. In line with this purpose, the chapter first describes the historical development of leadership, leadership theories and modern leadership styles, such as transactional, transformational, technological, strategic, visionary and agile leadership, and all these concepts are discussed based on the Industry 4.0 perspective.

Abstract
Purpose
The purpose of this research is to determine the competitive advantages of higher education institutions (HEIs) and create a new methodology to rank universities according to the competitive advantages.
Design/methodology/approach
The research determines the competitive advantages of HEIs by analysing expert opinions through a semi-structured interview form, matches codes and themes to performance indicators using Saldana's two-cycle coding methods, evaluates content validity through Lawshe and reveals the item weights of the ranking with analytical hierarchy process (AHP). Simple additive weighting (SAW) and Technique for Order of Preference by Similarity (TOPSIS) methods were used for ranking universities.
Findings
Seven dimensions stand out in regard to what should be considered while ranking HEIs: research and publication, education, management, infrastructure, financial resources, human resources and social and economic contribution. Under the 7 dimensions, 69 indicators were determined.
Practical implications
The research provides a scientific reference point where HEIs can compare themselves with other HEIs regarding where they are in the sector, especially in terms of competitive advantages.
Originality/value
Although there are many different ranking methods that rank universities in the national and international literature, almost all these methods are largely based on the outputs of the university such as the number of publications, the number of patents, the number of projects, etc. A framework which ranks universities by considering different aspects of the institution, such as management, human resources and financial resources, has not been developed yet. In this respect, this research aims to fill this gap in the literature.
