Abstract
Purpose
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.
Design/methodology/approach
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.
Findings
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.
Originality/value
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.

Abstract
Purpose
Student in-class participation is a crucial aspect in the learning process, including in synchronous learning process. Several variables may hinder students from actively participating in synchronous learning including communication anxiety. As behavior, student in-class participation can be modeled using theory of planned behavior (TPB) with communication anxiety as barrier variable. The current study aims to investigate student decision-making process to actively participate in synchronous online learning using TPB frameworks and examine the effect of communication anxiety as part of extended TPB.
Design/methodology/approach
This was quantitative nonexperimental research conducted by gathering cross-sectional data through electronic survey. A total of 1,009 Indonesian college students voluntarily participate in the survey. Structural equation modeling was used to analyze the data and test the hypothesis.
Findings
The results indicate that there was significant and positive effect between TPB-related variables: (1) attitude, (2) subjective norms, (3) behavioral control, (4) intention and (5) behavior. Communication anxiety, as an additional variable in the extended model, shows significant and negative effects on behavioral control and active participation behavior. However, the communication anxiety indicates insignificant effect on students’ intention to participate in online synchronous learning. The findings support the evidence that students’ intention to actively participate in synchronous learning can be described using TPB and communication anxiety hinders student to actively participate in synchronous learning.
Originality/value
The paper extends TPB on student active participation. Prior research limited to original theory of planned behavior (TPB) on student in-class and massive open online course (MOOC) participations, whereas the current research includes communication anxiety as additional variable on extended TPB to understand students’ intention to actively participate in synchronous online learning.

Abstract
Purpose
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).
Design/methodology/approach
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.
Findings
The findings revealed both GM and FK significantly influence IP, which is crucial to overcome SMEs’ resistance to go international.
Research limitations/implications
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.
Originality/value
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).
Abstract
Purpose
This paper aims to examine the friction and wear performance of the graphene synthesized from fruit cover plastic waste and oil palm fiber (OPF).
Design/methodology/approach
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.
Findings
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.
Originality/value
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.

Abstract
Purpose
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.
Design/methodology/approach
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.
Findings
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.
Research limitations/implications
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.
Originality/value
This paper identifies and encourages the need to study leadership style that is desirable among youth.

Abstract
Purpose
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.
Design/methodology/approach
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.
Findings
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.
Research limitations/implications
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.
Practical implications
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.
Originality/value
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.

Abstract
Purpose
The purpose of this study is to determine the best vaned diffuser design that can generate higher pressure output at a predetermined speed.
Design/methodology/approach
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.
Findings
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.
Originality/value
The study used the turbocharger with the impeller size 60 mm and adapted vaned diffuser to increase the output pressure.

Abstract
Purpose
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.
Design/methodology/approach
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.
Findings
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.
Research limitations/implications
In this study, all-inclusive scrutiny needs to be carried out for further exploration.
Originality/value
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.

Abstract
Purpose
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.
Design/methodology/approach
A survey with 400 respondents in Banten, Indonesia, was performed. The data were analyzed using multiple regression analysis.
Findings
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.
Research limitations/implications
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.
Practical implications
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.
Originality/value
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.
