This study aims to review relevant studies concerning consumer purchase of halal-certified products. A total of 35 studies related to the consumer purchasing behavior of halal-certified products in top-tier journals have been identified according to the recommended systematic literature review methodology.

A systematic literature review approach was implemented to examine, summarize and finally interpret the relevant research stream pertaining to consumer purchase of halal-certified products.

There are five research streams extracted from this systematic review, halal study context, theories adapted, covariance-based-structural equation modeling (SEM) vs partial least square-SEM, Muslim vs nonMuslim consumer and role of religiosity. Despite the growing interest in the quantitative approach in consumer purchase behavior in halal-certified products, scholars in halal consumer studies must have a greater extent of work. These include incorporating diverse theories in the framework, an advanced SEM approach, and relevant determinants to capture consumer purchasing of halal-certified products in the highly anticipated and profitable Muslim market.

Findings would help researchers in halal studies to consider and contemplate critical issues, according to the research stream presented in this review.

To the best of the authors’ knowledge, this study is the first review of quantitative studies on consumer purchases of halal-certified products.

The purpose of this study is to review the role of knowledge-sharing and its association with the Theory of Planned Behavior (TPB). TPB is the most used theory in understanding knowledge-sharing behavior in many contexts.

Based on the bibliometric approach, this study extracted and analyzed 229 journal articles on the Web of Science. In addition, two analyses (bibliographic coupling and co-word) were performed to provide science mapping in presenting the knowledge structure on the present and future research direction on knowledge-sharing and TPB.

The findings of this study suggest that two stand-out clusters are determinants and antecedents of knowledge-sharing behavior based on TPB and the role of the virtual platform and social media in facilitating knowledge-sharing among users.

This study will benefit researchers and scholars in studying individual behavioral traits underpinning TPB in achieving organizational excellence.

This study extends the findings of the previous review because of their limitations on methods. This study confirms the determinants of knowledge-sharing intention and behavior. However, this study suggests integrating TPB with other theories to provide more insights into knowledge-sharing behavior and use online and technology-based platforms to facilitate knowledge-sharing behavior.

The purpose of this study is to review cyberbullying incidents among students in higher education institutions (HEIs). Cyberbullying has become a threat to students' wellbeing as it penetrates one life due to the pervasive availability of digital technologies.

Through a bibliometric analysis, this study analyzes 361 journal publications from the Web of Science (WoS) based on bibliographic coupling and co-word analysis.

Significant themes were found related to cyberbullying in HEIs, particularly related to the impact and determinants of cyberbullying on students. Bibliographic coupling produces three clusters on the current research fronts, while co-word analysis produces four clusters on the prediction of future trends. Implications of this phenomenon warrant comprehensive intervention by the HEIs management to dampen its impact on students' wellbeing. Findings would enhance the fundamental understanding through science mapping on the prevalent and potential incidence of cyberbullying.

Crucial insights will benefit the government, HEIs’ management, educators, scholars, policymakers and parents to overcome this dreadful phenomenon of cyberbullying. Several managerial interventions and mitigation strategies are proposed to reduce and control the occurrence of cyberbullying.

This study presents a bibliometric review to uncover the knowledge structure of cyberbullying studies in HEIs.

This study aims to provide the current and future state of United Nations’ Sustainable Development Goals (SDGs) in the higher education institutions (HEIs). Since the SDGs’ proliferation, HEIs have played a crucial part in meeting the goals. Despite the central role of HEIs in accomplishing the SDGs, there has been little attention in providing a comprehensive overview of the SDGs in relation to HEIs.

A total of 280 publications in the Web of Science database were analyzed through a bibliometric approach consisting of citation analysis, co-citation analysis and co-occurrence of keywords analysis. This review explores the current state of SDGs, its central themes of research streams and predicts future direction in the context of HEIs.

The findings would assist stakeholders to strategize the SDGs on HEIs, including the government and policymakers, university top management, benefactors and academics. Three main research streams were observed sustainable curriculum; challenges and barriers of SDGs; and COVID-19 and health management.

Implications suggest that to achieve the stipulated goals in the SDGs, proper planning and strategy should be aligned proportionate to the national agenda.

This paper presents a novel knowledge structure by mapping the most relevant SDGs in the context of HEIs based on bibliometric analysis.

This study integrates the theory of planned behaviour (TPB) and value-belief-norm (VBN) theory to investigate tourists' intention and behaviour to visit green hotels in Malaysia.

A total of 160 valid questionnaire responses were collected via an online survey. The partial least square–structural equation modelling (PLS-SEM) technique was utilised to assess the study framework and the hypothesised relationship.

The study's results confirmed that tourists' intention to stay at a green hotel is directly influenced by their subjective norms and perceived behavioural control. Besides, the study confirms the insignificant relationship between green trust, personal norms and tourists' stay intention. On the other hand, perceived morals, responsibility, willingness to pay more and perceived consumer effectiveness were significant in explaining the customer's subjective norms, personal norms and perceived behaviour control.

The hotel industry may benefit from this empirical outcome to devise effective marketing strategies for retaining their customers, particularly in rejuvenating the impact of the COVID-19 pandemic on the industry.

This study provides valuable practical implications for green hotel operators to develop effective strategies to attract tourists to green hotel visits.

This study is the first to integrate the extended TPB and VBN theory to understand tourist intention to visit a green hotel. Notably, the extended TPB and VBN theory was practical and helpful in predicting tourist intention to visit a green hotel.

The purpose of this paper is to systematically review knowledge hiding (KH) behavior in higher education institutions (HEIs). KH is regarded as an unethical and antisocial behavior by many scholars, which should not be prevalent in HEIs.

A two-phase analysis through quantitative scientometric analysis and qualitative systematic literature review method through the preferred reporting items for systematic reviews and meta-analyses (PRISMA) model was applied. In phase 1,174 articles were analyzed using the VOSviewer through co-word and co-citation analyses. In Phase 2, 20 related studies on KH in HEIs were qualitatively analyzed on the fundamental concept of KH. The main themes were determined based on current research findings, through the identification of relevant gaps in the context of higher education.

In Phase 1, co-word and co-citation analyses resulted in six and three clusters, respectively. Subsequently, in Phase 2, five themes were discovered: terminology of KH, scale of KH, cultural and geographical context, KH among academics and students and relevant theories. Further, discussion on the institutional factors of individuals, organizations, technology and culture is presented.

This review lays out a practical guide to facilitate HEIs in managing KH behavior among academics, employees, and students. Strategies can be planned and implemented to foster and inculcate knowledge sharing behavior to circulate knowledge while at the same time diminishing KH behavior in HEIs.

To the best of the author’s knowledge, this study is the first to review KH behavior in the context of HEIs through quantitative and qualitative analysis.

The purpose of this study is to review the plethora of studies on knowledge management (KM) in the hospitality and tourism. The purposes of this paper through a bibliometric analysis via the VOSviewer tool are to analyze the current research stream and to assess emerging trends in KM in the tourism and hospitality field.

A total of 1,732 publications with 65,150 cited references were retrieved from the Web of Science to uncover the structure and intellectual base of studies in tourism with a KM perspective. Three bibliometric analyses were performed using VOSviewer software (citation, co-citation and co-occurrence of keywords); this study aims to uncover the knowledge structure of the past, current and future trends based on the bibliographic database by assessing the most influential past publication; determining the structure of the co-cited publications; and evaluating emerging trends for future studies.

This study produced two ground-breaking research streams inductively evaluated from the three bibliometric analyses: KM and digital technology; and innovation in tourism. Furthermore, the pressing issue of sustainability in tourism from the perspective of KM would be a crucial aspect in the tourism field. These streams would provide fundamental knowledge-based and further enhance the assimilation of KM within the tourism sector. The outcome would facilitate future scholars to link important tourism topics to benefit the tourism industry facing a competitive and challenging business environment.

This study contributes to the current theoretical understanding through thematic knowledge mapping of KM and the tourism and hospitality field.

To the best of the author’s knowledge, this study is the first to apply bibliometric analysis to the tourism and KM field by providing a basis for the most significant issue in tourism and the essence of emerging topics and trends.

The purpose of this paper is to systematically review knowledge hiding (KH) behaviors in the team context. KH behavior is regarded as unethical and antisocial behavior, detrimental to team development and performance. The nature of its existence should not be allowed in team activities.

Applying a systematic literature review, this study investigated 39 related quantitative studies on KH behavior of employees in team and group contexts. This study discusses the fundamental concept of KH, analyzes current research findings, identifies relevant gaps in the team and group context and sheds light on future direction.

Findings observed that the KH phenomena had gained the interest of scholars since the year 2010. Five main research streams identified in this systematic review are role of leadership, team creativity and innovation, underlying theory, multilevel modeling and KH scale.

The value of this paper is subjected to the specific notion of KH in team background where knowledge sharing should have been promoted instead of KH. This systematic review serves as insight and recognition on the importance of mitigating KH in team. Existing current literature, future research work and trends of KH in the organization may benefit from this new and anticipated behavior within the knowledge management field.

To the best of the authors’ knowledge, this review is the first to review KH behavior in the team context.

Academics research productivity is the pinnacle issue of higher learning institution (HLI) quest for providing the best service for the community and a country’s as a whole. Being productive in their area of expertise will determine how far HLI can challenge for the best education in the world. In lieu of this, knowledge sharing (KS) behavior determinants are assessed to determine what factors that can contribute to academic’s research productivity.

A quota sampling method was applied in selecting academics from public and private universities in Malaysia. A partial least square structural equation modelling (PLS-SEM) was used for analysis.

The results show that academics productivity explained variance is 22.6 per cent. This suggests that academics KS behavior has substantial impact on research productivity. As for determinants of academic’s attitude, academics commitment, trust and social network constituted an explained variance of 36.4 per cent. Management support has an explained variance of 38.7 per cent towards subjective norm, while facilitating condition and social media has an explained variance of 26.5 per cent towards perceived behavioral control (PBC). Academics KS intention and KS behavior explained variance were 62.1 and 47.1 per cent, respectively.

All the hypotheses result in significant relationship except for H1, commitment toward attitude. The impact of this study will be discussed in term of its theoretical and managerial perspectives.

The KS behavior in a multiracial and multinational country in Malaysia can be a benchmark for Asian countries in general.

This study investigates consumer purchases of energy-efficient appliances (EEAs). The adoption of EEA would reduce the detrimental impact of the environment from the consumer behavioral perspective.

This study evaluates consumer purchase of EEA based on the theory of planned behavior (TPB), environmental factors, and consumer energy-efficient behavior (EEB). Applying partial least square structural equation modeling (PLS-SEM), 412 household respondents within the five regions in Malaysia were analyzed.

Findings depicted that EEB has a significant influence on intention to purchase and subsequently purchasing behavior of EEA. Similarly, the TPB variables were significant predictors of EEB and intention to purchase except for attitude. Meanwhile, among the environmental factors, only environmental awareness was significant.

Implications include integrating educational programs through formal and informal measures. The former includes infusing within the mainstream educational system. On the other hand, the latter is through effective and captivating media communication.

The integration of EEB towards consumers' intention and behavior of purchasing EEAs.
