This study aims to investigate how job self-efficacy mediates the relationship between online knowledge sharing and employee innovation. To fully understand this relationship, this study also tests the moderating role of an innovative climate.

This study gathered data from 353 full-time employees working at information technology companies in Vietnam. This study used structural equation modeling to test hypotheses.

The results showed that online knowledge sharing positively influenced employee innovation directly and indirectly through job self-efficacy. Moreover, innovative climate positively affected employee innovation as well as moderated the nexus between online knowledge sharing and employee innovation.

First, this study provides further evidence that job self-efficacy plays a mediator linking online knowledge sharing with employee innovation. Second, this paper confirms that an innovative climate can play a mixed moderator that not only influences employee innovation but also moderates the association between online knowledge sharing and employee innovation.

The problem of image retrieval and image description exists in various fields. In this paper, a model of content-based image retrieval and image content extraction based on the KD-Tree structure was proposed.

A Random Forest structure was built to classify the objects on each image on the basis of the balanced multibranch KD-Tree structure. From that purpose, a KD-Tree structure was generated by the Random Forest to retrieve a set of similar images for an input image. A KD-Tree structure is applied to determine a relationship word at leaves to extract the relationship between objects on an input image. An input image content is described based on class names and relationships between objects.

A model of image retrieval and image content extraction was proposed based on the proposed theoretical basis; simultaneously, the experiment was built on multi-object image datasets including Microsoft COCO and Flickr with an average image retrieval precision of 0.9028 and 0.9163, respectively. The experimental results were compared with those of other works on the same image dataset to demonstrate the effectiveness of the proposed method.

A balanced multibranch KD-Tree structure was built to apply to relationship classification on the basis of the original KD-Tree structure. Then, KD-Tree Random Forest was built to improve the classifier performance and retrieve a set of similar images for an input image. Concurrently, the image content was described in the process of combining class names and relationships between objects.

From a consumer–brand relationship (CBR) perspective, this study proposes a serial multiple mediation model to explore the pathways (e.g. cognitive, affective and hybrid) to increase online celebrity brand equity (OCBE) and follower's hotel booking intentions (FBI).

Paper-based and online surveys were used to collect data from 443 respondents who had been using TikTok and had followed at least one online celebrity on TikTok, while that online celebrity had reviewed one or more types of accommodation. A serial multiple mediation model was evaluated through covariance-based structural equation modeling.

The results confirmed the hybrid cognitive–affective and cognitive–affective–conative pathways among antecedents and components of OCBE and FBI.

From a CBR perspective, this study provides a serial multiple mediation model to increase OCBE via hybrid cognitive–affective pathways and to drive FBI via cognitive–affective–conative pathways. These sequential relationships contribute to the human branding literature by defining a mechanism of how online celebrities can efficiently attract followers, thus driving online celebrity brand loyalty and hotel booking intentions.

The results should be validated in other cultural contexts to generalize findings and broaden the range of target respondents to include international followers and those within other nations.

COVID-19 pandemic has exposed that even the best of the developed nations have surrendered to the devastations imposed on the global supply chains. The purpose of this study is to explore how COVID-19 has exaggerated the supply chain of production and distribution of Taiwan-based face masks and also investigate the conscientious factors and subfactors for it.

In this study, an analytical hierarchy processes (AHP)-based approach has been used to assign the criterion weights and to prioritize the responsible factors. Initially, based on 26 decision-makers, successful factors were categorized into five main categories, and then main categories and their subcategories factors were prioritized through individual and group decision-maker’s contexts by using the AHP approach.

The results of this AHP model suggest that “Safety” is the most important and top-ranked factor, followed by production, price, work environment and distribution. The key informers in this study are stakeholders which consist of managers, volunteers, associations and non-governmental organizations. The results showed that good behavior of the employees under the “Safety” category is the top positioned responsible factor for successful production and distribution of face masks to the other countries with the highest global percentage of 15.7% and using sanitizers to protect health is the second most successful factor with the global percentage of 11.7%.

The limitations faced in this study were limited to only Taiwan-based mask manufacturing companies, and it was dependent on the decisions of the limited company’s decision-makers.

The novelty of this study is that the empirical analysis of this study has been based on a successful Taiwan masks manufacturing company and evaluates the responsible factors for the production and distribution of Taiwan masks to other countries during COVID-19.

This study focuses on Vietnamese international students who returned from their overseas doctoral education to home universities in Vietnam (henceforth Vietnamese overseas-trained returnees). The purpose is to explore the experience of these returnees “doing research” (i.e. being research active) when resuming a lecturing role at a Vietnamese regional university. In the context of research now receiving heightened attention in both the wider global higher education (HE) discourse and the Vietnamese HE sector, this study is timely and provides valuable insights.

In total, 76 Vietnamese overseas-trained returnees from varied disciplinary backgrounds completed a questionnaire on their research motivation and their perceived constraints doing research. Eighteen subsequently took part in semi-structured interviews. The study draws on the notion of human agency from the sociocultural perspective to understand the coping strategies of the Vietnamese overseas-educated returnees in response to the challenges they encountered.

The results show that the returnees' motivations to conduct research varied, fuelled by passion, but constrained by multiple factors. Time constraints, heavy teaching loads, familial roles and lack of specialized equipment are key inhibiting factors in re-engaging in research for these returnees. Addressing them necessitated a great deal of readaptation, renegotiation and agentive resilience on the part of the returnees in employing different coping strategies to pursue research.

The paper argues for a subtle understanding of the returnees' experience of re-engaging in research that is both complex and contextual. Implications are drawn for research development in the regional Vietnamese HE context and perhaps in other similar settings.

There is little empirical knowledge about how Vietnamese returned graduates – university lecturers – continue doing research after their return. Also underexplored in global discourse is research on foreign-educated returnees doing research, while they are an important source of human resources. The present study, therefore, fills these research gaps.

This article explores factors influencing the participation of industry professionals in Work-Integrated Learning (WIL) in three Vietnamese public universities. The impact of the unique socio-cultural background of Vietnam on WIL is also addressed.

A qualitative approach that included three focus groups and 15 individual in-depth interviews was applied. In total, 30 key university and industry WIL stakeholders were involved. Thematic analysis was employed to identify enablers and inhibitors to the participation of industry professionals in WIL in Vietnamese universities.

Industry professionals faced more challenges than support when involved in WIL in three Vietnamese public universities. Four enablers of their participation in WIL stemmed from industry and nine inhibitors emerged from a variety of sources. The overwhelming number of inhibiting factors indicated difficulties associated with implementing WIL.

The rationale behind limited industry involvement in Vietnamese universities has not been explored previously. A holistic understanding of all key WIL stakeholders’ perceptions of factors influencing industry participation in a non-Western tertiary context may provide leads for higher education policy in Vietnam and add to the international literature.

Vietnam is an emerging economy in the South East Asia region. Its Generation Z is gradually taking the lead in the country. But rather than breaking away from the previous generations, this generation also shows a strong preference towards local values and solid commitment to social issues. Thus, traditional culture elements are increasingly integrated in every aspect of Generation Z’s life, such as advertising and fashion. Instead of hanging out at coffee places, they go for bubble tea. They still appreciate the traditional values but integrate them within a modern context. Brands chase after these young people by adapting their values into their products and services. In the work place, the Vietnamese Generation Z is less confident. They are partially lost in career development with poor career counselling in the education system. They desire new experience and new learning opportunities. Generation Z, who were born beginning in 1995, emerges in Vietnam as a fresh and promising force.

Blockchain-based traceability technology (BTT) is an emerging digital technology that claims to have the potential to fulfil the demand for traceability to safeguard fruit safety. Drawing on the technological, organisational and environmental (TOE) framework, this study aims to investigate the perceived facilitators and barriers that influence the behavioural intentions of multiple stakeholders in the Vietnamese fruit supply chain (i.e., farmers, trading enterprises and consumers) to adopt BTT.

This study utilised a qualitative approach of semi-structured in-depth interviews with 60 stakeholders in the Vietnamese fruit supply chain to achieve the research objectives. NVivo 12 was employed to analyse the collected data using content and thematic analysis.

The findings identify several perceived facilitators that motivate BTT adoption. These include trust, transparency, business performance, the formation of alliances, consumer awareness of food safety and ethical agricultural practices, fruit branding and the pivotal role of farmers' cooperatives. Meanwhile, the perceived barriers to BTT adoption include a lack of digital literacy amongst the stakeholders, poor organisational culture, the high cost of traceability-enabled products and data privacy and security governance.

This study suggests that technology awareness and perceived facilitators and barriers should be incorporated into the design and deployment of blockchain-based traceability technology in the agri-food supply chain in developing countries.

To the best of the authors' knowledge, this study is the first qualitative paper that attempts to fill the research gap of understanding the perceived facilitators and barriers that influence the intentions of multiple stakeholders in the fruit supply chain to adopt BTT in the context of a developing economy.

Limited previous studies about Vietnamese returned migrant workers reviewed that a relatively high rate of migrants returned home before their contract ended. This paper aims to explore how the decisions to return were made under social lenses.

This paper analyses data obtained through in-depth interviews of contract workers who had worked in Taiwan with a focus on Phu Tho province in Vietnam.

The authors followed O’Reilly’s (2012) adaption of Practice theory in migration research to examine a group of Vietnamese labour migrants returning from Taiwan. Under this theory, external and internal structures are the two divisions of the social environment. The authors identified external structures that might enable or constraint migrant’s mobility. When negotiating internal structures, Vietnamese women might end their contract early in response to family obligations.

The findings provide insights into how women make their decisions when to return, which may contribute to a better understanding of how to assist women engaged in transnational labour migration.
