Abstract
Purpose
This study aims to investigate whether personal values can moderate the relationship between entrepreneurs’ job demands and their well-being.
Design/methodology/approach
The data from an email survey involving 307 entrepreneurs in the two largest cities in Vietnam were analysed.
Findings
The analysis results indicated that the values of self-transcendence, openness to change and self-enhancement, which were identified as personal resources in this study, can help entrepreneurs maintain positive well-being even when they face challenging job demands in their business ventures. In contrast, conservation values reinforce the negative influence of job demands on their well-being.
Practical implications
Practically, entrepreneurs are encouraged to develop certain personal values, and policymakers should endorse these values through policy proposals and amendments that facilitate entrepreneurship through education and reduced bureaucracy.
Originality/value
This study further extends Conservation of Resources theory based on the mechanism that entrepreneurs use their personal values as resources to mitigate the negative impacts of the job demands of entrepreneurship on their well-being.

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 paper aims to facilitate the joint assessment of issues related to the agricultural systems, i.e. agriculture, aquaculture and climate change (CC) response strategies, in the coastal districts with a panel of stakeholders; and to evaluate the level of agreement on the topics under consideration and potentially identify the most promising approaches to assessing CC affecting agricultural systems in the area and identify relevant and adequate response strategies.
Design/methodology/approach
Stakeholder Delphi technique – its assessment is an interactive method of qualitative research used to facilitate the interactive participation of varied and conceivably hierarchical and antagonistic stakeholder groups.
Findings
The most important result for the province is that the impact of climate change on agro-ecological landscapes (poverty and near river areas) is the duration of cold weather, more frequent and extreme. Moreover, Kendall’s W test gave a score of 0.547, which indicates a “strong” stakeholder agreement and the “confidence in ranks” being “high” in Thai Binh (Vietnam).
Originality/value
The scientific results in this study are intended to serve as relevant knowledge-inputs and direct contributions to capacity-building for the local partners (stakeholders and local authorities). These local partners are engaged in policy-making and effective planning and implementation of climate response measures in the districts in the province of Thai Binh.

Abstract
Purpose
From the customer-relationship theory and attachment theory approaches, this study proposes a serial mediation model to examine how celebrity attachment influences event attendees' intentions in the celebrity endorsement process in the context of events.
Design/methodology/approach
Paper-based and online surveys were used to collect data from 759 Vietnamese respondents, aged 15 and above, who followed domestic or international celebrities and were interested in various events taking place in Vietnam. A serial multiple mediation model was evaluated through covariance-based structural equation modeling.
Findings
The results confirmed the cognitive, affective and hybrid cognitive-affective pathways among antecedents, celebrity attachment and event participation intentions.
Research limitations/implications
Future studies need to validate these findings across diverse cultural settings and larger participant pools to enhance their applicability. Exploring celebrity endorsement for events from an international follower perspective could offer valuable insights. Future research should consider these factors when interpreting results. It may benefit from conducting longitudinal or mixed-method studies to improve generalizability. Additional moderating variables are necessary, as research on the celebrity endorsement process for events evolves.
Originality/value
This study contributes to the literature on celebrity endorsement within event marketing, emphasizing the customer-brand relationship and attachment theory. It extends existing research that primarily examines how celebrity attachment influences event attendees' intentions in the celebrity endorsement process by validating a serial mediation model.

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
The textile industry has consumed large quantities of water and discharged large volumes of wastewater in the dyeing process. The study aims to characterize self-dyed silk with Rhodamine B (RhB) for fashion applications to reduce textile hazards to the environment and increase the added value of silk.
Design/methodology/approach
Bombyx mori was fed with RhB-colored mulberry leaves (1500 ppm). The effects of self-dyeing were investigated via color strength K/S, Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscope, X-ray diffraction, tensile strength, color fastness to washing, rubbing, perspiration and light.
Findings
Self-dyed silk possesses effective coloration and impressive color fastness (4–5/5), higher crystalline index (CrI) (73.26 ± 2.28%), less thermal stability and tenacity, slight change in amino acid composition compared with the pristine and no existence of harmful aromatic azo amines and arylamine salts.
Practical implications
The application of self-dyed silk with RhB dye has expanded new technology into fashion industry, contributing partly to economic growth and adding value to silk in the global supply chain. Besides, the self-dyeing will yield practical values in the reduction of dyeing discharge in textile industry.
Originality/value
Self-dyed silk was characterized for textile applications in comparison with pristine silk in terms of color strength and fastness as well as determined its polymeric properties relating to crystallinity, morphology, chemical composition, tensile properties and thermal stability which have not been investigated before.

Abstract
Purpose
This study aims to explore how the inhibitor-loaded nanocontainers can be used in the epoxy coating for protection of steel against corrosion. A self-healing anticorrosive coating can be easily fabricated by embedding the inhibitor-loaded nanocontainers into the epoxy coating matrices. For this purpose, first, cerium (a catholic corrosion inhibitor) is encapsulated into silica nanoparticles (SiO2@Ce). Thereafter, an epoxy nanocomposite coating has been prepared on steel substrate using these SiO2@Ce nanoparticles as nanofillers.
Design/methodology/approach
To examine the effect of SiO2@Ce nanocontainers on mechanical properties of epoxy coating, the abrasion resistance, impact resistance and adhesion strength of coating have been evaluated. To reveal the effect of SiO2@Ce nanocontainer on corrosion behavior of epoxy-coated steel, the electrochemical impedance spectroscopy (EIS) has been conducted in NaCl solution.
Findings
Transmission electron microscopy and scanning electron microscopy/Energy-dispersive X-ray spectroscopy analyses indicate that Ce3+ cations have been successfully loaded into the surface of silica nanoparticles (at the content of approximately 2 Wt.%). Mechanical tests of epoxy nanocomposite coatings indicate that the nanocomposite coatings with nanoparticles content of 2.5 Wt.% provide the highest values of abrasion resistance, impact resistance and adhesion strength. EIS results show that the presence of SiO2@Ce3+ nanocontainers increases both coating resistance and polarization resistance. Along with the improvement the coating barrier performance, Ce inhibitor plays an important role in improving the anticorrosive performance at the steel–electrolyte interface.
Originality/value
The application of self-healing epoxy/SiO2@Ce nanocomposite coatings for the protection of carbon steel is very promising.
