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

The purpose of this paper is to develop an alternative new ternary geopolymer mortar (MKSP) to resolve a traditional mortar problem which exhibits several disadvantages, including poor strengths and surface microcracks and the CO2 air pollution.

Design/methodology/approach

The MKSP ternary binder was produced using metakaolin (MK), slag (S), and palm oil fuel ash (POFA) activated with an alkaline mixture of sodium silicate (Na2SiO3) and 10 M NaOH in a mass ratio of 2.5. Seven different mix proportions of MK, slag, and POFA were used to fabricate MKSP mortars. The water-to-binder ratio was varied between 0.4 and 0.5. The mortars were heat cured for 2 h at 80°C and then aged in air. Flexural stress and strain, mortars flow and compressive strength were tested. Furthermore, the mortars were characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM) analyses.

Findings

The results showed that the sample MKSP6, which contained 40 percent MK, 40 percent slag, and 20 percent POFA, exhibited high compressive strength (52 MPa) without any cracks and flexural strength (6.9 MPa) at 28 days after being cured for 2 h at 80°C; however, the MKSP7 mortar with optimal strength of 55 MPa showed some surface cracks . Further, the results of the XRD, SEM, and FTIR analyses indicated that the MKSP mortars primarily consisted of a crystalline (Si+Al) phase (70 percent) and a smaller amorphous (Si+Ca) phase (30 percent).

Research limitations/implications

The MKSP ternary geopolymer mix has three limitations as an importance of heat curing for development early strength, POFA content less than 20 percent to gain high normal strength and delaying the sitting time by controlling the slag content or the alkali activator type.

Practical implications

The use of geopolymer materials binder in a real building is limited and it still under research, Thus, the first model of real applied geopolymer cement in 2008 was the E-Crete model that formed by Zeobond company Australia to take the technology of geopolymer concrete to reality. Zeobond Pty Ltd was founded by Professor Jannie S.J. van (van Deventer et al., 2013), it was used to product precast concrete for the building structure. The second model was PYRAMENT model in 2002 by American cement manufacturer Lone Star Industries which was produced from the development carried out on inorganic alumino-silicate polymers called geopolymer (Palomo et al., 1999). In 2013 the third model was Queensland’s University GCI building with three suspended floors made from structural geopolymer concrete containing slag/fly ash-based geopolymer (Pathak, 2016). In Australia, 2014, the newly completed Brisbane West Wellcamp airport becomes the greenest airport in the world. Cement-free geopolymer concrete was used to save more than 6,600 tons of carbon emissions in the construction of the airport. Therefore, the next century will see cement companies developing alternative binders that are more environmentally friendly from a sustainable development point of view.

Originality/value

Production of new geopolymer binder of mortar as alternative to traditional cement binder with high early and normal strength from low cost waste materials, less potential of cracking, less energy consumption need and low carbon dioxide emission.

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

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

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.

Abstract

Purpose

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).

Design/methodology/approach

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.

Findings

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.

Originality/value

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.

Abstract

Purpose

The current work provides a framework for the ranking of ontology development methodologies (ODMs).

Design/methodology/approach

The framework is a step-by-step approach reinforced by an array of ranking features and a quantitative tool, weighted decision matrix. An extensive literature investigation revealed a set of aspects that regulate ODMs. The aspects and existing state-of-the-art estimates facilitated in extracting the features. To determine weight to each of the features, an online survey was implemented to secure evidence from the Semantic Web community. To demonstrate the framework, the authors perform a pilot study, where a collection of domain ODMs, reported in 2000–2019, is used.

Findings

State-of-the-art research revealed that ODMs have been accumulated, surveyed and assessed to prescribe the best probable ODM for ontology development. But none of the prevailing studies provide a ranking mechanism for ODMs. The recommended framework overcomes this limitation and gives a systematic and uniform way of ranking the ODMs. The pilot study yielded NeOn as the top-ranked ODM in the recent two decades.

Originality/value

There is no work in the literature that has investigated ranking the ODMs. Hence, this is a first of its kind work in the area of ODM research. The framework supports identifying the topmost ODMs from the literature possessing a substantial amount of features for ontology development. It also enables the selection of the best possible ODM for the ontology development.

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 reveal empirical facts that literacy and marketing strategies effectively impact people using Sharia pawn products during the COVID-19 pandemic because of the pressure of capital needs and financial difficulties.

Design/methodology/approach

This study used an exploratory qualitative research approach through semi-structured interviews with six partners of different productive ages and social, economic and educational backgrounds. After data reduction, presentation, description and validation, this paper develops the theory and presents it as a qualitative thematic analysis.

Findings

The findings of this study revealed that those who had socialised Sharia pawnshops had a low literacy level. Nonetheless, the socialisation of Sharia pawnshops increases literacy and public understanding of pawnshop products in Sharia pawnshops. This issue arises because of the COVID-19 pandemic, which makes it impossible for Sharia pawnshops to hold an event or socialise.

Originality/value

The authenticity of this study proves that literacy and marketing strategies can increase public awareness of Sharia pawn products during the COVID-19 pandemic.

Abstract

Purpose

This paper aims to explore the contextual role of social-cultural capital in youth entrepreneurship between Malaysia and Lao PDR/Laos, comparing two different entrepreneurial ecosystems designed to identify emergent factors that stimulate and/or stifle the genesis of youth entrepreneurship while identifying similar and divergent entrepreneurial identities and traits among young people from these two sovereign contexts.

Design/methodology/approach

Utilizing qualitative-based case study design approach, data collections were garnered from 30 informants through in-depth personal interviews, focus group studies coupled with personal observation conducted via purposive cum snowball sampling.

Findings

Thematic analysis reveals a pattern-based outcome that discloses a variety of inter-related factors within the social network ecosystem that stimulate and sometimes stifle youth entrepreneurship, primarily through the active agency of social-cultural capital.

Practical implications

Entrepreneurial ecosystem contextual differences between Malaysia and Laos demonstrate the unifying factor of social-cultural capital through social network in stimulating youth entrepreneurship and unveiling practical similarities and differences that can be used to promote youth entrepreneurial endeavors among varying sovereign socio-economic contexts in ASEAN (Association of Southeast Asian Countries).

Originality/value

This study specifically focuses on the unambiguous contextual differences of two sovereign entrepreneurship ecosystems. Contextual differences may not necessarily demarcate further the gulf of differences within and between two sovereign entrepreneurship ecosystems but, on the contrary, may close the gap through the dynamic role of social-cultural capital via social network ties in youth entrepreneurship.
