The purpose of this study is to explore the applications of 3D printing in space sectors. The authors have highlighted the potential research gap that can be explored in the current field of study. Three-dimensional (3D) printing is an additive manufacturing technique that uses metallic powder, ceramic or polymers to build simple/complex parts. The parts produced possess good strength, low weight and excellent mechanical properties and are cost-effective. Therefore, efforts have been made to make the adoption of 3D printing successful in space so that complex parts can be manufactured in space. This saves a considerable amount of both time and carrying cost. Thereof the challenges and opportunities that the space sector holds for additive manufacturing is worth reviewing to provide a better insight into further developments and prospects for this technology.

The potentiality of 3D printing for the manufacturing of various components under space conditions has been explained. Here, the authors have reviewed the details of manufactured parts used for zero-gravity missions, subjected to onboard international space station conditions and with those manufactured on earth. Followed by the major opportunities in 3D printing in space which include component repair, material characterization, process improvement and process development along with the new designs. The challenges like space conditions, availability of power in space, the infrastructure requirements and the quality control or testing of the items that are being built in space are explained along with their possible mitigation strategies.

These components are well comparable with those prepared on earth which enables a massive cost saving. Other than the onboard manufacturing process, numerous other components as well as a complete robot/satellite for outer space applications were manufactured by additive manufacturing. Moreover, these components can be recycled onboard to produce feedstock for the next materials. The parts produced in space are bought back and compared with those built on earth. There is a difference in their nature, i.e. the flight specimen showed a brittle nature, and the ground specimen showed a denser nature.

This review discusses the advancements of 3D printing in space and provides numerous examples of the applications of 3D printing in space and space applications. This paper is solely dedicated to 3D printing in space. It provides a breakthrough in the literature as a limited amount of literature is available on this topic. This paper aims at highlighting all the challenges that additive manufacturing faces in the space sector and also the future opportunities that await development.

The pandemic's health and social issues have significantly altered the character and manner of teaching and learning in higher education across the country. The use of technology to replace or integrate face-to-face learning with online learning has become a necessary requirement for promoting and continuing learning processes. Furthermore, integrating technology is a goal of Sustainable Development Goal 4 (SDG 4) to make teaching and learning more innovative and sophisticated. This paper is based on a systematic review grounded in a synthesis of research papers and documents analyzing the current status of teachers' pedagogy through online learning modes in the context of Pakistan.

Through content analyses of academic studies in higher education and reflection on the online teaching experiences, this study discusses how students' learning is associated with teachers' teaching approaches in the modern era of digitalization and innovation.

The review and analysis suggest that online teaching is not viewed as an innovative phenomenon; rather, teachers simply teach their traditionally designed face-to-face courses through the use of technology. The paper suggests that transforming teachers' pedagogical insight to make online learning sustainable is an urgent need for higher education.

The analysis provides a basis for consideration of teacher learning and quality education (SDG #4) to fulfill the nation’s agenda for sustainable development. The analysis helps educators and administrators in higher education institutions reflect on their policies and practices that have short- and long-term effects on students' learning outcomes.

The purpose of this study is to investigate the moderating impact of corporate governance (CG) on the relationship between economic policy uncertainty (EPU) and the sustainable growth (SG) of Chinese firms.

The study collects data of 975 Chinese non-financial listed firms for the period from 2010 to 2017. The study measures SG using a comprehensive index based on nine financial indicators and applies industry and year fixed effects regression to investigate the direct and moderating impact of CG on the relationship between EPU and SG of Chinese firms.

The results of the study explain that EPU negatively affects SG, while concentrated ownership, board independence and board gender diversity (BGD) positively contribute to the SG of the Chinese firms. The results also explain that concentrated ownership and BGD reduce the negative impact of EPU on the SG of the Chinese firms.

The study considers only non-financial firms; therefore, the results of this study cannot be generalized for financial firms. Future research can be carried out while considering financial firms as a unit of analysis.

The investigation of the negative impact of policy uncertainty on SG is essential for the government and policymakers to devise policies to reduce uncertainty. The investigation of the moderating effect of CG enriches the literature on corporates’ response to policy uncertainty. It provides valuable insights for corporates regarding CG mechanisms to attain SG.

To the best of the authors’ knowledge, this is the first study that investigates the moderating impact of CG on the SG of Chinese firms using an index-based measurement of SG.

This study aims to identify the factors that influence Malaysian non-Muslim consumers’ perception towards buying halal food products.

A structured close-ended questionnaire was used for data collection through a random distribution to 500 non-Muslim consumers from various states in Malaysia.

Using SPSS package, the factor analysis was able to identify three main variables. Later, the hypotheses were tested using structural equation modelling. This study has indicated that the perception of non-Muslim consumers about halal food products is influenced by their attitude, subjective norm and perceived behavioural control, specifically in the context of Malaysia.

This finding will help both the academics and the industry food makers in understanding the perception of non-Muslim consumers towards the concept of halal food products.

The outcome of the study can serve as a useful reference to relevant Malaysian statutory bodies on the current perception of the Malaysian non-Muslim consumers towards Malaysian halal agenda. This will also help the industry food makers to serve their customers better as well as maximize their profit through a well-planned marketing campaign.

It prepares a sound basis for Malaysian policymakers to promote the involvement of Malaysian non-Muslim entrepreneurs within the halal food service industry with the intent of improving the socio-economic strata of its participants and, at the same time, fulfilling their religious obligations in providing halal foods for fellow Muslims.

Because very few researches have studied non-Muslim consumers’ perception towards halal food products, the development of halal food theory will help in capitalizing the practices in non-Muslim countries.

This paper contributes to risk management research with reference to disclosure of risk specific information within the oil and gas industry. This paper provides empirical evidence regarding voluntary and mandatory disclosure behaviour from both a quantitative and qualitative perspective.

A longitudinal empirical study examines probabilistic reserve quantum reporting of UK companies, over a time-period spanning voluntary and mandatory disclosure. The researchers analyse disclosure behaviour under voluntary and mandatory time spans using a logistical regression approach to measure determinants of risk reporting. Form of regulation is considered as the fundamental driver for disclosure whilst controlling for other relevant variables. Implications for developing international regulation are presented with suggestions for further research.

Mandatory reporting is not seen as a significant influence to disclosure. Degree of risk, quality of audit firms, level of stock exchange and organisational visibility each impact on disclosure. The findings indicate that a mandatory disclosure approach is ineffective, partially explained by mimetic and normative forces and a balancing of agency-related costs and benefits. There is an inverse relationship between level of risk and risk reporting.

Generalisation of the findings is limited due to the specific context of the extractive industry.

The paper seeks to inform the International Accounting Standards Board's (IASB) on-going consideration of risk reporting and also its extractive industries deliberations.

The paper provides original insight into the area of risk management with particular focus on risk specificity and quantitative metrics for risk profiling not previously tested. The paper introduces risk profiling as a variable in risk disclosure.

International students are considered as a huge and potentially lucrative segment for various products of the tourism industry in Malaysia. One of the tourism products is the local food they consume. The purpose of this paper is to investigate key factors that contribute to international students’ intention to consume Malay food. Drawing on the theory of planned behavior (TPB), the present study examines the impact of attitude, subject norm and perceived behavioral control (PBC) on international students’ intention to consume Malay food.

A quantitative approach using self-administered questionnaire was adopted. A total of 163 samples were collected from international students studying in five different Malaysian higher education institutions. A partial least squares structural equation modeling technique was used to test the hypothesized model.

The findings highlight that attitude, subject norms and PBC significantly motivate international students to consume local food. The subject norm toward consuming local food was revealed as the strongest predictor of international students’ intention to consume Malay food.

Although this is one of the early studies that uses the TPB in assessing the factors that influence international students’ intention to consume local food, this paper is driven by and aimed for practical consideration and thus making a significant contribution to practice. Specifically, the findings of the present study provide important implications for tourism industry practitioners to plan and implement initiatives that may promote local food among international students studying in Malaysian institutions.

This paper aims to review 69 studies related to Muslim consumer behavior and determine the relationship between these topics and Islamic rationality. In addition, this paper elaborates on Al-Ghazali’s Islamic rationality model.

A text analytics approach is used to map 69 studies on Muslim consumer behavior. In addition, the historical-critical and inductive approach is used to identify Muslim scholars’ concepts and opinions regarding Islamic rationality, especially Al-Ghazali.

This study confirms that Muslim consumer behavior is in line with the concept of Islamic rationality proposed by Al-Ghazali. This is evidenced by a strong awareness of Islamic morals and values, which fosters a high commitment to halal products.

The findings of this study will provide essential benefits in the development of Islamic rationality theory, which can then be used as an alternative in explaining Muslim consumer behavior and also can be used as a reference for stakeholders in the industry to mainstream halalfication on products offered in the Muslim market.

The value of originality in this study lies in identifying the relation between Islamic rationality and Muslim consumer behavior, and this effort was confirmed through 69 selected studies related to Muslim consumer behavior.

The present study investigates the moderating role of customer trust in customer relationship management (CRM) components and customer loyalty relationships in the context of the baking sector in Bangladesh.

Data were collected through a survey using a structured questionnaire from 350 customers of commercial banks in Bangladesh.

The key finding is that all CRM components (customer orientation, customer advocacy and customer knowledge) except customer engagement have positive impact on customer loyalty. Moreover, customer trust only moderates the relationship between customer knowledge and customer loyalty, whereas other CRM components and customer loyalty do not moderate by trust.

The findings of the study add to the substantial pool of knowledge on CRM components, customer trust and customer loyalty literature. More specifically, the moderating role of customer trust between customer knowledge and customer loyalty is the novel contribution of this research which will enrich the existing CRM literature particularly in the banking sector of Bangladesh.

The innovation of cryptography technique and blockchain has made cryptocurrency an alternative medium of exchange due to its safety, transparency and cost effectiveness. But its main feature cannot be separated from the users who use cryptocurrency for their illegal transactions. There are several arguments related to the legality of cryptocurrency. The purpose of this paper is to analyze the nature of cryptocurrency based on characteristics of money, legal perspective, economic perspective and Sharia perspective.

In this study, the methodology used is descriptive with a qualitative approach. The object of this research is cryptocurrency. The data are secondary data obtained from peer-reviewed journal articles, conference papers review, working paper and Sharia consultant reports addressing the legality of cryptocurrency. The literature review analysis includes the following steps: material collection, descriptive analysis, discussion with people in Sharia competency and intuitive-subjective material evaluation.

Regarding the characteristic of money, cryptocurrency is acceptable. But in terms of the legal perspectives, cryptocurrency does not meet the criteria as currency. From the economic perspective, cryptocurrency does not fully meet the characteristic currency due to high price volatility, and from the Sharia perspective, cryptocurrency can be considered property (mal) but not as a monetary value (thamanniyah).

The research findings are based on the journal articles, working paper and Sharia consultant report, and it may lack Sharia’s opinion. Any further discussion related to Sharia perspectives will be a great input to enrich the study.

This study also includes the implications related to the opportunities and the risks of cryptocurrency that can be discussed for the development of the cryptocurrency in the future.

This study includes the implication cryptocurrency is using as nature of money and not as speculative instrument.

This study argued the legality of cryptocurrency in four perspectives such as the nature of money, legal, economy and Sharia perspective.

The purpose of this paper is to investigate the role of trust in enhancing customer loyalty, and to test the mediation role of commitment and customer intimacy in the relationship between trust and customer loyalty.

A total of 500 questionnaires were distributed and 200 were returned (40 percent response rate), and a structural equation modeling technique was used to test the hypotheses.

The results of this study show that trust has a significant relationship with commitment and customer intimacy but no significant relationship was found with customer loyalty. Commitment and customer intimacy have a significant relationship with customer loyalty. The mediation analysis reveals that commitment and customer intimacy play a mediation role in the relationship between trust and customer loyalty.

This study indicates that commitment and customer intimacy affect customer loyalty. The role of commitment and customer intimacy as a mediator between trust and customer loyalty indicates that customers are committed to continuing and maintaining the relationships with Islamic banks.

This study provides empirical evidence on interrelationships between trust, commitment, customer intimacy and customer loyalty in banking relationships.
