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 explore the strategic integration of Sharia-compliant and environmental, social and governance (ESG)-focused investments within global equity portfolio optimization frameworks, with a particular emphasis on variance minimization and dynamic rebalancing techniques.

The research uses historical data from Sharia-compliant, ESG-focused and conventional equity exchange-traded funds (ETFs). Advanced mean-variance optimization methodologies via quadratic programming are employed, encompassing static optimization with and without a 50% cap on individual asset weights, dynamic optimization with monthly rebalancing and rolling window optimization.

Portfolios integrating Sharia-compliant investments frequently outperform those composed solely of conventional equity ETFs. Dynamic optimization with monthly rebalancing achieved the highest Sharpe ratio (1.3708) and demonstrated enhanced portfolio resilience during market turbulence, such as the COVID-19 pandemic. Sharia-compliant investments showed substantial allocations during key periods, with weights reaching up to 100% in the first half of 2020. In contrast, ESG-focused investments exhibited more limited and sporadic allocations, reflecting a more opportunistic role in the portfolio.

The findings reaffirm the critical role of Sharia-compliant investments in well-diversified, risk-conscious portfolios while also providing nuanced insights into the more selective integration of ESG-focused assets. The results offer practical guidance for portfolio managers seeking to integrate ethical and sustainable investment principles within advanced portfolio optimization frameworks, particularly when focusing on minimizing variance and dynamically responding to evolving market conditions.

The study contributes to the growing body of literature on ethical and sustainable investments, demonstrating that it is possible to balance ethical considerations with robust financial performance. The research underscores the potential for Sharia-compliant investments to play a significant role in global portfolios, potentially fostering greater financial inclusion and cross-cultural understanding in the investment community.

This research provides novel insights by focusing on Sharia-compliant investments within non-Muslim countries, an area that has been relatively underexplored. It also compares the outcomes of static, dynamic and rolling optimizations, highlighting the dynamic interplay between ethical investment principles and financial performance.

This study examined the revisit intention of tourists in Muslim-friendly hotels in nexus with Halal-friendly hotel attributes (social environment, facilities, food and beverage, locals and staff, and services), corporate image, customer engagement, perceived value, and service encounter evaluation. It further examined the mediating role of corporate image, customer engagement and perceived value between Halal-friendly hotel attributes and service encounter evaluation.

Using a structured survey instrument, 390 valid responses were gathered from international tourists who visited Malaysia. The collected data were analyzed using Partial Least Squares – Structural Equation Modeling (PLS-SEM) to test the assumed relationships.

The research shows that corporate image (CI), customer engagement (CE), and perceived value (PV) are directly influenced by Halal-friendly hotel attributes (HFHA) and exert influence on service encounter evaluation (SEE). Findings also suggest the mediating effect of CI, CE, and PV between HFHA and SEE. SEE further positively and significantly enhances the revisit intention and positive word-of-mouth.

The findings of this study stipulate that hotel owners should ensure the presence of HFHA in their offers to retain their existing guests and ensure their positive communication towards potential visitors through developing a fascinating image, engagement, and lucrative value.

Grounded on the attribution theory, this study contributes to the Halal tourism literature by exploring the role of Halal-friendly hotel attributes in enhancing the hotel’s image, customer engagement, and perceived value to enhance positive service encounter evaluation and revisiting intention for the hotel.

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 study proposes the integrated Qardhul Hasan and equity-based microenterprise development (IQEMD) model, a financial model for microenterprises in Muslim nation such as Afghanistan. This study aims to overcome the significant challenges these businesses face in securing financial resources, offering a tailored, sustainable solution to enhance their operations.

This study collected primary data via a survey from 466 microentrepreneurs in Kandahar, Afghanistan. Data analysis was performed using partial least squares with SmartPLS 4 software. The study’s validation of the proposed financial model among microenterprises was grounded in the theory of reasoned action, ensuring a solid theoretical basis for its findings.

The findings of this research revealed that the attitudes and subjective norms of Afghan microentrepreneurs positively influence their intention to use IQEMD Model. These findings provide important guidance for financing ventures and policymakers, highlighting the IQEMD model’s potential to improve financial strategies and practices for microenterprises in Afghanistan.

This study focuses solely on microenterprise development in Afghanistan, with its sample size and study area being clear constraints. Therefore, caution is advised when interpreting the results, which may not be broadly applicable. The reliance on current factors may also restrict the exploration of other important determinants affecting microenterprises’ behavioral intentions toward using the IQEMD model. Future research should consider incorporating new factors to optimize the IQEMD model and include interviews with more stakeholders to increase its validity.

The findings of this paper offer microenterprises an alternative source of financing to start or expand their businesses. This study holds implications for government and policymakers. By incorporating a nonprofit organization as suggested in this model, it assists the government in reducing expenditures associated with the development of microenterprises.

This study is a pioneering effort in merging Qardhul Hasan and equity-based financing for microenterprise development. It significantly contributes to existing research by underscoring the effectiveness and impact of such financing as a viable source for these enterprises. These strategies could notably boost productivity, employment and gross domestic product growth. The study enhances understanding of alternative financing models in the microenterprise sector.

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.
