This study explores the relationships among multiple factors, including growth mindset, lifelong learning and continuous professional development (CPD), influencing teachers’ integration of information and communication technology (ICT) into their teaching methods.

The study involved 1,095 Indonesian vocational high school teachers who participated in in-service or preservice teacher development programs. Data was collected through a survey, and a structural equation model with partial least squares parameter estimation was used to analyze the relationships and mediations.

Structural equation modeling revealed that a growth mindset positively affects both lifelong learning and CPD. Moreover, lifelong learning positively impacts CPD. Furthermore, all of these variables demonstrate a positive effect on teachers’ ICT integration in the classroom. The findings indicate that lifelong learning and CPD partially mediate the relationship between a growth mindset and ICT integration.

This study contributes to the literature on the determinants of teachers’ ICT usage postparticipation in in-service and preservice teacher programs. The findings underscore the significant impact of a growth mindset on teachers’ ICT use in the classroom.

The purpose of this study is to investigate the influence of top management capabilities inclusive of global mindset (GM), foreign knowledge (FK) and international firm performance (IP).

This paper opted for a descriptive study using structured questionnaires involving 118 Malaysian small medium enterprises (SMEs) that are currently marketing their products abroad with halal JAKIM certification. Multiple regression analysis was applied to test the influence of the two variables on international performance.

The findings revealed both GM and FK significantly influence IP, which is crucial to overcome SMEs’ resistance to go international.

This study only focusses on the niche market which is halal export product, thus the findings may not be generalized to other sectors. Furthermore, the firm size might also influence the significant contribution of top management.

This paper is a part of ongoing study of internal capabilities and international firm performance among SMEs halal product manufacturers in developing countries.

This paper aims to examine the friction and wear performance of the graphene synthesized from fruit cover plastic waste and oil palm fiber (OPF).

The graphene was synthesized by using a chemical vapor deposition method, where a copper sheet was used as the substrate. The dry sliding test was performed by using a micro ball-on-disc tribometer at various sliding speeds and applied loads.

The results show that both as-grown graphenes decrease the coefficient of friction significantly. Likewise, the wear rate is also lower at higher sliding speed and applied load. For this study, OPF is proposed as the best solid carbon source for synthesizing the graphene.

The main contribution of this study is opening a new perspective on the potentials of producing graphene from solid waste materials and its effect on the tribological performance.

The purpose of this paper is to investigate the styles that are desirable in a leader in the perspective of youth in Asia, particularly Brunei Darussalam and South Korea. Thus, by investigating it using the Path Goal Theory as its approach, this study provides leaders with the desirable leadership style to motivate and influence the youth.

The research used a quantitative method with a proportionate stratified sampling method using the criteria of age of youth defined by UNESCO. The data then collected using a face-to-face method of a questionnaire from February 2016 till June 2016.

The evidence depicts that Bruneian youth prefers directive leadership while South Korean youth prefers supportive leadership. This finding is based on the selected styles that are desirable by the youth and their choice is also influenced by culture. This may imply that culture has a large impact which can determine the leadership styles best suited to the environment.

Since the research has limited sample sizes and geographical location, this can lead to future research by considering more regions of different continents to determine whether different leadership preference still persists. This study can also be used as a basis to consider other factors in investigating leadership preference in Asian countries.

This paper identifies and encourages the need to study leadership style that is desirable among youth.

This study aims to examine the impact of the COVID-19 pandemic on the relationship between auditors’ work stress and client participation with audit quality (AQ).

This study is a descriptive-survey type and the data were collected through a questionnaire distributed online. The statistical population consisted of auditors working in audit firms in Iran and the sample was selected using a random sampling method. Structural equation modeling was used to analyze the data.

The findings of this study suggest that the COVID-19 pandemic exacerbated the negative relationship between auditors’ work stress and AQ. In addition, the results indicate that client participation in the audit process did not significantly impact AQ during the COVID-19 pandemic.

Given the global and widespread impact of the COVID-19 pandemic on individuals’ lives and work settings, this study provides an opportunity to explore the challenges auditors face concerning health protocols and their well-being during the pandemic, specifically within the context of Iran. The unique circumstances of the pandemic have placed additional pressure on auditors to navigate and address the challenges arising from COVID-19 in their workplaces. Although research on the effects of the pandemic on accounting and auditing is ongoing, this study contributes to the literature by expanding our understanding of the specific implications and circumstances faced by auditors during the COVID-19 outbreak.

This research aims to test the simultaneous effects of the perceived threat of COVID-19, e-health literacy, e-health access barrier, loyalty toward healthy foods in general, loyalty toward functional foods, the affordability of healthy foods in general and the affordability of functional foods on health-related quality of life (HrQoL) during the COVID-19 pandemic.

A survey with 400 respondents in Banten, Indonesia, was performed. The data were analyzed using multiple regression analysis.

The results of the research showed that HrQoL during the COVID-19 pandemic was positively affected by e-health literacy and the affordability of healthy foods in general while negatively affected by the e-health access barrier, the perceived threat of COVID-19 and loyalty toward healthy foods in general. Furthermore, HrQoL was not influenced by loyalty toward and affordability of functional foods.

This research was conducted in Banten. Due to the operational limitations during the COVID-19 pandemic, this research used a purposive sampling technique. Therefore, the next research should retest the model in different contexts and locations.

To improve HrQoL during the COVID-19 pandemic, citizens need to be educated on finding and utilizing credible online health information during the COVID-19 pandemic. Governments and health service providers should also strive to offer ease of access to credible online health information. Furthermore, the affordability of healthy foods, in general, should be managed well.

A few studies on HrQoL during COVID-19 pandemic were performed. However, there is a lack of paper that examines the role of food customer loyalty and affordability in a model of HrQoL during the COVID-19 pandemic. To the best of the authors’ knowledge, this paper is the first that involved and tested the role of food customer loyalty and affordability in a model of HrQoL during the COVID-19 pandemic.

During Covid-19 pandemic, Millennials, which are familiar with the Internet, may contribute in facing the pandemic by consistently sharing healthy food information. Thus, it is important to improve Millennials online healthy food information-sharing behaviour during the Covid-19 pandemic. This research aims to examine the simultaneous effects of e-health literacy, knowledge of the digital health communication media (DHCM) use, facilitating conditions, information quality and source credibility on Millennials' online healthy food information-sharing behaviour during the Covid-19 pandemic.

A survey was performed to collect the data. The respondents of the survey are 205 DHCM millennial users who lived in Tangerang Regency and Tangerang City, Indonesia. This research performed a multiple regression analysis to test the conceptual model and proposed hypotheses.

Millennials' online healthy food information-sharing behaviour during the Covid-19 pandemic was significantly affected by perceived threat of Covid-19, knowledge of the DHCM use and the facilitating conditions. However, it was not significantly affected by e-health literacy, information quality and source credibility.

This research employed a purposive sampling technique. This research also was conducted only in Tangerang Regency and Tangerang City, Indonesia. In order to test the stability of the research findings, future research should be conducted in other contexts.

In order to improve Millennials' online healthy food information-sharing behaviour during the Covid-19 pandemic, it was essential to educate Millennials on the importance of healthy food consumption during the Covid-19 pandemic and their relationships. It is also important to enrich Millennials' knowledge of reliable and trustworthy online health information sources, such as the DHCM, and the search method. Furthermore, the facilitating conditions of online healthy food information-sharing behaviour should be improved.

It is well known that online healthy food information-sharing behaviour is important during Covid-19 pandemic. However, there is lack of study that specifically focused on Millennials' online healthy food information-sharing behaviour during the Covid-19 pandemic. This paper is the first that develops and tests a model of Millennials' online healthy food information-sharing behaviour during the Covid-19 pandemic. The model can be used to understand the behaviour and develop intervention strategy.

The purpose of this study is to determine the best vaned diffuser design that can generate higher pressure output at a predetermined speed.

Several vaned diffusers of thin, flat-type design with different number of blades and blade angle were fabricated. The vaned diffusers were fitted inside the turbocharger compressor and test on a cold-flow turbocharger test rig. A Taguchi L₂₇ orthogonal array is selected for analysis of the data. Influence of number of blades, blade angle and rotational speed on output pressure is studied using the analysis of variance (ANOVA) technique. Finally, confirmation tests are conducted to validate the experimental results.

The optimum design parameters of the vaned diffuser using signal-to-noise ratio analysis were six blades type, blade angle of 18° and rotational speed of 70,000 rpm. Results from ANOVA showed that the speed has the highest influence on output pressure. The number of blades and blade angle produced the least effect on the pressure output.

The study used the turbocharger with the impeller size 60 mm and adapted vaned diffuser to increase the output pressure.

This study aims to scrutinise the impact of fibre length and its composition on the tribological attributes of oil palm fibre (OPF) polymeric composite as an alternative brake friction material.

Fabrication of the sample was conducted by using a hot-compression method. The tribological test was carried out by deploying a ball-on-disk tribometer. Analysis of the data was then done by using the Taguchi approach as well as analysis of variance.

The results indicated that all design variables (fibre composition, length and treatment) are not statistically significant, as all p-values are greater than 0.05. Remarkably, irrespective of the fibre treatment, the wear rate and coefficient of friction (COF) distribution suggested that a smaller fibre length with a high fibre composition might enhance the composite’s tribological performance with COF of 0.4 and wear rate below than 1 × 10^–9 mm³/Nm. The predominant wear mechanisms were identified as micro-cracks, fine grooves and fibre debonding.

In this study, all-inclusive scrutiny needs to be carried out for further exploration.

The main contribution and novelty of this study are opening a new perspective on the formulation of new substances from bio-based material (i.e. OPF) that possess superior tribological characteristics for friction-based applications.

This study aims to introduce a novel technique which helped in quantifying the wear performance of a roller chain which was lubricated by using the palm oil-based hexagonal boron nitride (hBN) nanoparticles (nano-biolubricant).

The efficiency of the nano-biolubricant was evaluated by using a custom-made roller chain tribometer, at different resistance torque values at a constant speed and running time. Prior to the test, 2 different lubrication conditions were applied. The mass loss and elongation behaviour of a roller chain was selected as a degradation metric for monitoring the amount of the chain wear. The predominant wear mechanism of a roller chain was identified by surface morphological analysis.

Regardless of the lubrication conditions, the wear performance of the roller chain was significantly increased, at increasing resistance torque values. Higher wear was noted when the roller chain was lubricated using a nano-biolubricant, however, the wear curve showed a promising high chain life. The predominant wear mechanism involved is abrasive wear.

Although an increase in the elongation during running is based on the wear between the pins and roller, none of the earlier studies quantified the wear performance of a roller chain under differing lubrication conditions. Hence, for bridging the gap, this study described a new method for measuring the wear performance of the roller chain which was lubricated using the palm oil-based hBN nanoparticles or a nano-biolubricant.
