Abstract
Purpose
The health and environmental hazards associated with synthetic dyes have led to a revival of natural dyes that are non-toxic, environmentally benign and coupled with various functions. The study aims to investigate and develop the potentiality of a popular herb called Chromolaena odorata (C. odorata) as a sustainable and stable dyestuff in textiles.
Design/methodology/approach
Natural colorant extracted from C. odorata leaves is used to dye the worsted fabric, which is one of the premier end-use of wool in fashion, via the padding method associated with pre-, simultaneous and post-mordanting with chitosan, tannic acid and copper sulfate pentahydrate. The effects of extraction, dyeing and mordanting processes on fabric’s color strength K/S and color difference ΔECMC are investigated via International Commission on Illumination’s L*a*b* color space, Fourier transform infrared spectroscopy, scanning electron microscope, color fastness to washing, rubbing, perspiration and light.
Findings
The results obtained indicate extraction with ethanol 90% with a solid/liquid ratio of 1:5 within 1 h, and coloration with a liquor ratio of 1:5 (pH 5) within 2 h under padding pressure of 0.3 MPa are the most effective for coloring worsted fabric.
Practical implications
The C. odorata’s application as a highly effective dyestuff possessing good colorimetric effectiveness has expanded this herb's economic potential, contributing partly to economic growth and adding value to wool in global supply chain.
Originality/value
C. odorata dyestuff has prevailed over other natural colorants because of its impressive color fastness against washing, rubbing, perspiration and especially color stability for pH change.

Abstract
Purpose
This study aims to investigate the conditional indirect effect of academic self-efficacy in the interplay between academic motivation and academic satisfaction through academic engagement among university students.
Design/methodology/approach
A cross-sectional study was performed on 1,638 Vietnamese university students (31.9% males and 68.1% females) aged 16 to 36 (Mean = 20.06, SD = 1.428). The participants filled out a questionnaire with the Vietnam versions of the General Self-Efficacy Scale, Academic Motivation Scale, Academic Life Satisfaction Scale and Academic Engagement Scale. Model 4 and Model 7 in the PROCESS macro were used for the mediation analysis and the moderated mediation analysis.
Findings
Results showed that the indirect effect of academic engagement on the academic motivation-academic satisfaction link was significant. Furthermore, academic self-efficacy moderated this indirect effect. The indirect effect was stronger among students with high academic self-efficacy and weaker among students with low academic self-efficacy.
Originality/value
This study’s findings contribute to educational research on academic satisfaction and can be used by institutions of higher education and educators to enhance academic satisfaction among university students.

Abstract
Purpose
Cambodian and Laotian students (CLS) are among the largest groups of international students in intra-ASEAN student mobility as well as in Vietnamese higher education institutions (HEIs). However, little has been researched on the factors influencing CLS’s decision to choose Vietnam as destination country. The purpose of this study is to investigate why CLS decide to go overseas and choose Vietnam as their host country among other opportunities as well as their perceptions of the decision.
Design/methodology/approach
Using qualitative methods and employing purposive sampling, data were collected by semi-structured interviews from CLS studying in a HEI in the Mekong Delta of Vietnam. The data were analysed against the push–pull framework to understand factors influencing the participants’ decision.
Findings
The findings show that CLS in the study were “pushed” by the perceived higher value of a foreign qualification and family encouragements. In terms of pull factors, they were attracted to choose Vietnam as the host country most observably due to scholarship opportunities. However other pull factors were also significant, especially the lack of certain skills in home countries and its congruence with Vietnam’s competitive strength in offering courses for those skills. In retrospect, the participants expressed a sense of optimism, though there was also certain reservation.
Research limitations/implications
The small sample restrict the generalisability of the findings.
Practical implications
As an exploratory study, the findings can lay the ground for largerscale studies investigating CLS mobility in Vietnam and be employed for inbound student mobility policymaking reference for HEIs in Vietnam as well as in other developing countries.
Originality/value
This study investigates why Cambodian and Laotian international students decide to go to Vietnam, a developing country in the lesser-known part of international student mobility landscape. This is a topic that remains under-researched in the Asia-bound student mobility literature. Insights from the study can not only contribute to the scholarly gap but also offer implications for HEIs in Vietnam and other Asian countries.

Abstract
Purpose
The purpose of this study is to present an exploration of green intrinsic motivation’s mediating role in the relationship between socially responsible human resource management (SRHRM) and employee workplace green behaviour. Additionally, green leadership behaviour’s moderating role within this relationship is investigated.
Design/methodology/approach
Data were collected via a survey using a convenience sampling approach with a sample of 300 employees in Vietnam. A path analysis and the bootstrapping technique in the SPSS Process macro were used to test the hypotheses.
Findings
The results demonstrate that employee green intrinsic motivation mediates the association between SRHRM and workplace green behaviour. Furthermore, the findings indicate that green leadership behaviour attenuates the mediation.
Practical implications
The findings suggest that managers should be aware of green intrinsic motivation’s role in encouraging employee workplace green behaviour that results from SRHRM implementation. Organisations should provide resources and enact policies to promote green intrinsic motivation and foster employees’ engagement in workplace environmental activities. Additionally, organisations must be aware of the potentially negative impact of green leadership behaviour and proactively ensure that such actions are authentic, aligned with SRHRM practices, applicable to employees’ work and administered carefully to prevent the perception of micromanagement.
Originality/value
This is the first study to examine green intrinsic motivation as the underlying psychological mechanism and green leadership behaviour as the boundary condition that affects the relationship between SRHRM and employee workplace green behaviour.

Abstract
Purpose
The COVID-19 lockdown has forced many organizations and employees to work from home. In such uncertain and unprecedented context, it is crucial for organizations to stimulate their employees’ creativity to adapt to new working environment and thus to sustain and improve organizational performance. This paper aims to examine how to stimulate employees’ creativity by focusing on their online knowledge sharing (OKS) behaviors, their use of online platforms and their organizations’ innovation climate in a working from home (WFH) context because of the lockdown. For empirical analysis, this research uses data from Vietnam – a developing country in the Southeast Asia.
Design/methodology/approach
Data are collected from employees working in Ho Chi Minh City but WFH during the COVID-19 lockdown. Structural equation models are used for analyzing the data.
Findings
Online platform use and organizational innovation climate are positively associated with creativity directly and indirectly via the mediating roles of internal and external OKS.
Research limitations/implications
This research provides policymakers, organizational leaders and managers with an important evidence on how to stimulate creativity by emphasizing the roles of knowledge sharing, online platforms and innovation climate. Accordingly, relevant practical implications are also drawn to sustain or improve organizational performance in the context of WFH context because of COVID-19 lockdown. This research also contributes to knowledge management literature by providing an evidence on the relationships between online platform use, organizational innovation climate, OKS and creativity.
Originality/value
This research is among the early attempts that explore the associations between employees’ use of online platforms, their organizations’ innovation climate, their internal and external OKS behaviors and their creativity in the context of WFH because of a lockdown.

Abstract
Purpose
Farmers' risk attitudes and risk perceptions play an essential role in shaping risk management strategies to address risks and uncertainties. Contract farming is considered as one of the feasible approaches to tackle farmers' concerns. However, risk perspectives under various categories have not been included in studies on farmers' preferences for contract farming in the literature, especially in Vietnam. This study aims to determine factors affecting farmers' choices of different contract farming practices.
Design/methodology/approach
The explanatory factor analysis (EFA) and multinomial logit model (MNL) were applied to explore the impacts of risk perspectives on farmers' preferences for contract farming. Data have been collected from 211 rice farmers in An Giang Province, “the rice bowl” of the Mekong Delta, Vietnam.
Findings
The study found that farm size, cooperatives, extension, market access and trust have significantly impacted on contract participation while a delay payment was a barrier for farmers' motivation to opt for the contract. Farmers' contract choices were also influenced by their risk attitudes and perceptions under different risk dimensions. The financial, policy and human risk-averse behavior predisposed farmers to single out the full contract while the policy and human risk-loving and production, market and finance risk-averse respondents were in favor of the marketing contract. Moreover, the findings indicated that the more farmers concerned about risk of weather and market, the more choices for the full contract, whereas the risk perceptions of weather and policy encouraged farmers to use the limited contract. By contrast, farmers who perceived the impacts of risk of diseases/pests and human were likely to adopt the marketing contract.
Research limitations/implications
This study just focuses on collecting data from farmers’ perspective. Future studies involving stakeholders such as enterprises and policy makers are strongly recommended so as to design suitable contracts and enforce contract schemes effectively in Vietnam.
Originality/value
The findings also contribute to the literature on different types of contracts and the multidimensional aspect of risk for rice production in Vietnam.

Abstract
Purpose
Dehydrated bacterial cellulose’s (BC) intrinsic rigidity constrains applicability across textiles, leather, health care and other sectors. This study aims to yield a novel BC modification method using glycerol and succinic acid with catalyst and heat, applied via an industrially scalable padding method to tackle BC’s stiffness drawbacks and enhance BC properties.
Design/methodology/approach
Fabric-like BC is generated via mechanical dehydration and then finished by using padding method with glycerol, succinic acid, catalyst and heat. Comprehensive material characterizations, including international testing standards for stiffness, bending properties (cantilever method), tensile properties, moisture vapor transmission rate, moisture content and regain, washing, thermal gravimetric analysis, derivative thermogravimetry, Fourier-transform infrared spectroscopy and colorimetric measurement, are used.
Findings
The combination of BC/glycerol/succinic acid dramatically enhanced porous structure, elongation (27.40 ± 6.39%), flexibility (flexural rigidity of 21.46 ± 4.01 µN m; bending modulus of 97.45 ± 18.20 MPa) and moisture management (moisture vapor transmission rate of 961.07 ± 86.16 g/m2/24 h; moisture content of 27.43 ± 2.50%; and moisture regain of 37.94 ± 4.73%). This softening process modified the thermal stability of BC. Besides, this study alleviated the drawbacks for washing (five cycles) of BC and glycerol caused by the ineffective affinity between glycerol and cellulose by adding succinic acid with catalyst and heat.
Originality/value
The study yields an effective padding process for BC softening and a unique modified BC to contribute added value to textile and leather industries as a sustainable alternative to existing materials and a premise for future research on BC functionalization by using doable technologies in mass production as padding.

Abstract
Purpose
This study aims to develop a strategic framework for the success of coastal urban projects in Vietnam, which is one of the Asia Pacific countries significantly affected by climate change.
Design/methodology/approach
A questionnaire was used to collect data from practitioners in Vietnam. Principal component analysis (PCA) technique was used to identify critical success factors (CSFs) of coastal urban projects. A strategy map for the success of coastal urban projects was also proposed using the balanced scorecard (BSC) method.
Findings
This study identified 41 project success factors that could contribute to project success, and thence, extracted 11 CSFs for coastal urban projects using the PCA technique. In addition, 11 key performance indicators (KPIs) for coastal urban projects were listed and their linking with project success factors and CSFs was explored. Furthermore, a strategy map for the success of coastal urban projects was proposed using the BSC method. The strategy map included five perspectives: learning and growth, internal processes, social and environmental performance, financial performance, and stakeholders' satisfaction.
Originality/value
This study identified 11 CSFs for coastal urban projects and proposed a strategy map for the success of coastal urban projects.

Abstract
Purpose
Cham Muslims are both an ethnic and religious minority group. Although reports indicate a bleak situation regarding school attainment and success, little research has been conducted exclusively on the experiences of Cham Muslims in Vietnam’s educational system. This study aims to investigate the challenges and supports that Cham Muslims may encounter during their years in public education. Additionally, this study explores how Islamic elements are received in various educational settings.
Design/methodology/approach
Using qualitative methods and purposive sampling, semi-structured interviews were conducted with Cham Muslim students enrolled in two Vietnamese universities. The data were analyzed to address the research questions and were interpreted through the lens of Bourdieu’s concepts of field and capital, as well as Appadurai's (2004) notion of “capacity to aspire.”
Findings
The findings of this study suggest that Cham Muslim students may encounter unique challenges compared to other ethnic groups residing in mountainous regions. Various forms of support, both from the state and individuals, have been identified as facilitators of educational engagement. However, this study also highlights the challenges associated with Islamic practices in both pre-collegiate and university environments.
Research limitations/implications
Given the exploratory nature of this study, the findings should be interpreted cautiously to avoid overgeneralization. While additional sources were consulted for substantiation, the small sample size limits the generalizability of the results. However, this study can serve as a foundation for future research investigating the experiences of Cham Muslims in Vietnamese education institutions. Larger-scale studies conducted in multiple locations would contribute to the literature on ethnic and religious minorities, which often requires in-depth analysis using various theoretical approaches.
Originality/value
This study is among the pioneering efforts to investigate Cham Muslims’ educational experiences in Vietnam, which has the potential to contribute to both the ethnic and religious minority studies.

Abstract
Purpose
This study aims to explore how ephemeral content marketing enhances brand love and customer engagement, with a focus on the mediating role of brand authenticity, self-brand connection and advertising value.
Design/methodology/approach
This research was conducted using a quantitative method through an online questionnaire with a sample of 728 in Vietnam, analyzing data by using the partial least squares structural equation modeling model.
Findings
This study evaluates ephemeral content marketing through six dimensions: entertainment, trendiness, informativeness, interactivity, aesthetic quality and perceived relevance. The findings indicate positive mediating roles of advertising value, self-brand connection and brand authenticity on the impact of ephemeral content marketing on brand love and customer engagement.
Research limitations/implications
This study provides a comprehensive model of factors affecting consumer perceptions of ephemeral content marketing, which can help businesses to proactively formulate strategic responses for consumers on social media platforms with ephemeral content features. This also allows them to precisely target their audience, avoiding ineffective and costly advertising efforts on social media when content quality is lacking.
Originality/value
This research sheds light on the six essential dimensions of effective ephemeral content that adds value to customers, ultimately leading to their love and active engagement. This substantial addition to the field of social media marketing opens up possibilities for further investigation of the dynamics across different forms of social media marketing, such as short-form videos or in various contexts such as tourism, fashion, food products and education, particularly in the context of ephemeral content in emerging markets such as Vietnam.
