The purpose of this paper is to present a review of empirical studies on principal leadership in Singapore. It seeks to provide a general picture of Singapore principals’ leadership qualities, styles, and roles.

This is a systematic review of empirical studies, using a “bounded” approach with a focus on the main findings of the reviewed studies. In all, 36 studies were selected for the interview. The findings of these studies were open coded, synthesized, and clustered into different themes.

The review revealed several qualities, characteristics, styles, and enacted roles of Singapore principals. While there are similarities between Singapore principals and principals elsewhere in the world, the review brought out some features unique to Singapore principals.

This review contributes to the growing literature in comparative research on principals’ leadership and their enacted roles, and concurrently functions as a guide for further research on school leadership in Singapore.

This purpose of this paper is to review the progressive development in bilateral trade and investments between China and the Association of the Southeast Asian Nations (ASEAN) since 1970. China's economic reform has served as a great incentive for ASEAN countries to engage in continuous political and economic dialogue with the economic giant as it is considered as one of the largest, growing markets in the world. The political and economic efforts initiated by ASEAN have sought to affirm an outward‐looking ASEAN in playing a pivotal role in the international community and advancing ASEAN's common interests, which include economic trade with China as regional partner.

A review of the literature based on secondary data provides the analysis of the stages of the Chinese political and economic reforms that had brought about improvement in the economic relationship between China and ASEAN.

The findings comprise reports that highlight the promising trend in investment relations between China and ASEAN.

The paper highlights the need for further in‐depth analysis of Chinese political and economic reforms that will have a significant impact on regional trade and investment in the Asia‐Pacific region.

The paper will allow international managers of multinational enterprises to have a better appreciation of the political and economic developments in China and to consider options to enhance greater business partnerships with Chinese corporations.

The literature gap in this particular area of study presents an opportunity to explore new developments in the Chinese Government's economic reforms.

The growing use of internet-based learning (IBL) platforms in institutions of higher education is producing profound changes in the traditional teaching learning process worldwide. This paper aims to identify and understand the ways in which higher education institutions draw benefits by the use of such means, synthesizing the literature research.

The study synthesized the literature research by using a mixed method approach in which both Web of Science (WoS) and bibliographic techniques were used to retrieve the relevant data base.

The comprehensive review of the literature suggests that communication technology (CT), massive open online courseware (MOOCs), social networking sites (SNSs), blogs, real simple syndication (RSS) and YouTube are creating new possibilities and avenues of collaborative learning by transforming the traditional class and teacher-centric system.

Multiplicity of the IBL platforms and rapid technological obsolesce are some of the limitations of this paper.

The findings of this study are highly useful in developing a strategic framework to accelerate the integration of IBL platforms to make teaching learning process more interactive and informative.

This study aims to review the recent advancements in high entropy alloys (HEAs) called high entropy materials, including high entropy superalloys which are current potential alternatives to nickel superalloys for gas turbine applications. Understandings of the laser surface modification techniques of the HEA are discussed whilst future recommendations and remedies to manufacturing challenges via laser are outlined.

Materials used for high-pressure gas turbine engine applications must be able to withstand severe environmentally induced degradation, mechanical, thermal loads and general extreme conditions caused by hot corrosive gases, high-temperature oxidation and stress. Over the years, Nickel-based superalloys with elevated temperature rupture and creep resistance, excellent lifetime expectancy and solution strengthening L12 and γ´ precipitate used for turbine engine applications. However, the superalloy’s density, low creep strength, poor thermal conductivity, difficulty in machining and low fatigue resistance demands the innovation of new advanced materials.

HEAs is one of the most frequently investigated advanced materials, attributed to their configurational complexity and properties reported to exceed conventional materials. Thus, owing to their characteristic feature of the high entropy effect, several other materials have emerged to become potential solutions for several functional and structural applications in the aerospace industry. In a previous study, research contributions show that defects are associated with conventional manufacturing processes of HEAs; therefore, this study investigates new advances in the laser-based manufacturing and surface modification techniques of HEA.

The AlxCoCrCuFeNi HEA system, particularly the Al0.5CoCrCuFeNi HEA has been extensively studied, attributed to its mechanical and physical properties exceeding that of pure metals for aerospace turbine engine applications and the advances in the fabrication and surface modification processes of the alloy was outlined to show the latest developments focusing only on laser-based manufacturing processing due to its many advantages.

It is evident that high entropy materials are a potential innovative alternative to conventional superalloys for turbine engine applications via laser additive manufacturing.
