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

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.

The authors estimated the hidden overhead (capital diversion or wasteful use of capital) of Vietnam state-owned enterprises (SOEs).

Abstract

Purpose

The authors estimated the hidden overhead (capital diversion or wasteful use of capital) of Vietnam state-owned enterprises (SOEs).

Design/methodology/approach

The authors used a panel data set of 10,200 Vietnam SOEs observed over the period 2010–2018. The authors modeled and estimated the hidden overhead by using a stochastic production frontier. The hidden overhead parameter is modelled as the technical inefficiency in the production function.

Findings

Vietnam SOEs are very capital intensive. The hidden overhead (or the wasteful use of capital) is very high with an average rate of 69%.

Research limitations/implications

Alternative estimation methods should be used to account for endogeneity in production inputs. Lack of comparison with the Vietnam private firms.

Originality/value

The paper proposes an original way to quantify hidden overhead (or capital diversion) in the Vietnam SOEs. The finding (a capital diversion rate of 69% on average) is astonishing. It calls for an urgent and profound reform of the Vietnam SOEs.

Abstract

Purpose

This study aims to explore the impact of social, financial and institutional factors on women’s entrepreneurship in Vietnam, emphasizing motivation’s role in addressing challenges. Women’s entrepreneurship holds economic significance, driving local economies and creating opportunities. Government efforts to support women entrepreneurs have increased, but research on this in developing economies, especially in Vietnam, is limited.

Design/methodology/approach

The paper investigates women’s entrepreneurship in Vietnam, examining social, financial and institutional influences and emphasizing motivation in overcoming challenges. Using a qualitative approach, it conducts in-depth interviews with 28 female entrepreneurs, analyzing data thematically. Methodologically, the study uses purposive sampling, triangulation and member checking to enhance credibility.

Findings

Findings reveal key motivations like financial incentives, self-achievement and social impact. These motivations empower women to overcome financial constraints, skill gaps, limited support and societal perceptions. This research guides women entrepreneurs to enhance success through learning, persistence, skill development and self-awareness.

Originality/value

This paper presents a novel exploration into women’s entrepreneurship in Vietnam, offering original insights into the interplay of social, financial and institutional factors, with a spotlight on motivational drivers. It provides unique perspectives on their motivations, challenges and support mechanisms. The study’s contribution lies in its comprehensive understanding of women’s entrepreneurship dynamics in a developing economy like Vietnam, offering valuable insights for policymakers, practitioners and academics alike. Its originality lies in its holistic approach and nuanced examination, enriching the discourse on women’s entrepreneurship in emerging

Abstract

Purpose

This article aims to provide a theoretical unifying framework for workplace Confucian culture and employees’ organizational commitment (OC) through the modelling role of moral identities. The context is education in Vietnam.

Design/methodology/approach

Based on employees’ OC theory, a theoretical model was built. Administrative staff and teachers were asked to participate in the study with the assistance of preschool educational institutions in Vietnam. A survey was performed, and data from 421 participants were collected. The moderated structural equation technique was used to test hypotheses.

Findings

The study has demonstrated the positive impact of workplace Confucian culture applications on employees’ perceptions and participation in corporate social responsibility (CSR). The study also confirms the positive impact of employees’ perceptions and participation in CSR. In addition, another conclusion is the moderating effect of moral values on the relationship between workplace Confucian culture and aspects of CSR.

Research limitations/implications

The study focuses on Confucian-culture employees in workplaces, suggesting that their perception of CSR may differ from those from other backgrounds. The authors then plan to state the comparison in further research. The main finding of the study is that WCC and CSR affect employee OC, but there are other factors that could be influenced by WCC and CSR. Future research should explore these factors to improve the current model.

Practical implications

Confucian ideology has been constructed and developed for a long time, but this study has examined its practical implications for favourably effecting human behaviour, thereby demonstrating its potential in organizational culture and practical application.

Social implications

This theoretical framework can be profitably used in educational organizations.

Originality/value

The study adds to the body of research on OC in two ways. The first way is to explain how a beneficial organizational factor – the Confucian workplace culture – contributes to employees’ OC. The second way involves examining the effects of moral identity on participation and perception of CSR.

Abstract

Purpose

In the apparel industry, suppliers play a significant role, directly affecting customer service levels and business profits. Integrating sustainable requirements into supplier selection not only aligns with global environmental goals but also enhances business performance, social responsibility and overall industry well-being. This study aims to design a multi-criteria model to evaluate and select the most sustainable suppliers in the fashion industry, trying to balance the conflicts in the set of sustainable development criteria.

Design/methodology/approach

The integration of analytic hierarchy process (AHP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) offers advantages in sustainable supplier selection within the apparel industry. The AHP plays a crucial role in engaging multiple decision-makers with conflicting criteria to reach a consensus during the decision-making process. Conversely, the TOPSIS is used to compute alternative ratings. By simultaneously determining criteria weights and incorporating stakeholder preferences, hybrid models enhance decision-making strength and overcome limitations observed in classical multi-criteria decision-making techniques.

Findings

This research identified and classified 16 critical criteria impacting the selection of apparel industry suppliers, focusing on sustainable development. The criteria were weighted, providing a robust statistical foundation for the selection model. The results indicated that the most influential criteria were staff training, production capability, flexibility and practice of recycling. The proposed sustainable supplier selection model explains to decision-makers how criteria influence supplier ranking results compared to traditional models, supporting managers in making informed and sustainable supply chain decisions through continuous updates and enhancements.

Originality/value

This research provides new insight into the weighted impact of factors related to sustainable supplier selection in the apparel industry. The combination of a precise process and scientific knowledge will improve the quality of sustainable supplier selection.

Abstract

Purpose

This study aims to estimate the pass-through rate of the increases in the excise tax and TCF tax on tobacco in Vietnam. This study seeks to shed light on how the tax burden is split between consumers and producers and inform policy discussions in the country. Using panel micro-level data collected from three waves of a nationwide retailer's survey, this study provides an evidence-based pass-through estimation for tobacco tax in Vietnam and contributes to the understanding of tax policy on smoking and smoking-related issues.

Design/methodology/approach

Following increases in the excise tax and TCF tax on tobacco in 2019, the differential effect of the tax hike on the “treatment group” (domestic cigarettes) versus the “control group” (illicit cigarettes) using a difference-in-difference (DID) analysis has been studied. The study utilized unique longitudinal retailers’ data on cigarettes prices in Vietnam from 2018 to 2019 to estimate the tax pass-through rate for some of the most popular factory-made cigarette brands.

Findings

This study found evidence of an over-shifting of cigarette taxes on smokers. Specifically, it discovered that the tax increase is absorbed more by low-priced brand smokers compared to premium brand users due to (1) the limited increase in prices under a pure ad valorem system and (2) the way the Vietnamese currency is denominated. Additionally, there is evidence of cushioning to mitigate price shock on consumers as the real prices increase gradually over the period of one year after the tax change.

Originality/value

To the best of the authors’ knowledge, this study is the first to collect and analyze a unique panel micro-level data from three waves of a nationwide retailers’ survey, which captures the changes in marketing and pricing strategies of the tobacco industry in Vietnam before and after an increase in excise tax in 2019. The results of this study could be used as a reference for future policymakers in considering increasing taxes on tobacco.

This study explores the perceptions of Australian employers regarding the benefits and challenges of micro-credentials within higher education and enablers of their effectiveness.

Abstract

Purpose

This study explores the perceptions of Australian employers regarding the benefits and challenges of micro-credentials within higher education and enablers of their effectiveness.

Design/methodology/approach

A qualitative approach that included 11 semi-structured interviews with employers affiliated with an Australian university was used. A deductive thematic approach was employed to analyse the data.

Findings

Micro-credentials were generally seen to be beneficial for an array of people, including employees, employers, customers and communities – stakeholders in all environmental layers of micro-credentials’ ecological system. Findings also indicated that both challenges of micro-credentials and enablers of their effectiveness depended heavily on attributes of learners, employers and higher education providers. The conclusion is that, based on the evidence of this study, micro-credentials within higher education are worth trialling.

Originality/value

Although research interest in micro-credentials is growing, few empirical studies have investigated micro-credentials’ benefits, challenges and enablers of effectiveness, especially from the perspective of employers. The study carries practical and policy implications for those involved with micro-credential research and development.

Abstract

Purpose

The purpose of the study is to explore the interrelation between internal factors of learners and the external environment. The results of this study help to design a learning environment that improves students' self-efficacy and consequently self-regulated learning (SRL) behaviors of students.

Design/methodology/approach

The study adopts a quantitative approach to explore the relationship between learner's self-efficacy, self-regulation behavior and three factors in the online learning environment: course design, learning activities and relationship with instructors and peers. Participants of the study are 350 students in two universities in Vietnam.

Findings

The study finds that factors in the learning environment namely course design, learning activities and relationship within class significantly affect students' self-regulation. Moreover, results show that students' self-efficacy plays the mediating role in the relationship between learning environment and self-regulation.

Research limitations/implications

Samples are taken by convenience sampling method, which may lead to sampling bias, and results may, to some extent, be misleading. The study was conducted in only two universities with limited student populations. A larger sample of students from other institutions may contribute to a better explanation of the relationships.

Practical implications

The study has a practical implication of contributing to the limited understanding of learners in an underdeveloped-research country context. The study also implies necessary changes to the long-standing, prevalent yet ineffective teaching and learning style.

Social implications

The study calls for a renovation in the nation's traditional educational practices, having a social implication of creating a learning environment beneficial for learners.

Originality/value

This study is the first to investigate the impact of online learning environment and students' internal factors on their learning behaviors in Vietnam. The study is among the very few empirical research studies on the country's education generally and on self-regulation specifically, contributing to better understanding of learning experiences and the improvement of teaching.

Abstract

Purpose

This paper intends to analyze a social enterprise as a case example of fulfilling social missions and achieving financial profitability at the same time. This paper aims to illustrate a business partnership that helps to bridge the gap in business and employment opportunities between megacities and suburban areas and examine value-creating activities that generate healthy income stream for the business.

Design/methodology/approach

This paper follows a quantitative methodology in the form of case study. The data are collected through interviews, personal observation and document analysis; direct quotes from interviewees are used to describe the phenomenon. Value chain framework is adopted to analyze company activities and deduce key success factors as well as value creations of the company.

Findings

The case demonstrates that social enterprises can be self-sustained financially, which would help them to better fulfill their social missions. Financial profitability can be achieved through good management of production, marketing and sales activities. Besides, value creation achieved through activities in the value chain is not only for customers but also for suppliers – a beneficiary within the social impact created by the case company.

Practical implications

The case demonstrates the necessity of establishing strong alliance with suppliers and customers in ensuring business success, which implies that leaders need to equip themselves with good business skills. Entrepreneurship support should include educational and training assistance besides the usual legal and financial support.

Social implications

The case provides an exemplary partnership model that helps social enterprises to achieve financial security and social mission at the same time. This model can be applied anywhere in the world to create benefits for vulnerable communities.

Originality/value

The case study contributes to the limited understanding of social entrepreneurship in Vietnam, and demonstrates a social innovation in business partnership that helps to diminish the inequality of income and employment opportunities between suburban areas and big cities.
