Abstract
Purpose
This study aims to enhance to corrosion protection of NiZn-plated steel by electroplating multilayer coating.
Design/methodology/approach
The multilayer coating consists of three layers on mild steel substrate, such as Cr3+ chromate conversion layer (CCC), electrodeposited nanosilica zinc-nickel composite layer (ZnNiSi) and electrodeposited zinc-nickel alloy layer (ZnNi). Its morphology, composition and corrosion behaviour were investigated by various methods.
Findings
Polarization curves indicated that polarization resistance and corrosion current density of CCC/ZnNiSi/ZnNi/Fe (6.956 kO.cm2; 2.56 µA.cm−2) were two times higher and five times lower than that of ZnNiSi/ZnNi/Fe (3.42 kO.cm2; 12.52 µA.cm−2), respectively. From electrochemical impedance spectroscopy data, charge transfer resistances were 1.344, 2.550 and 2.312 kO.cm2 for ZnNi, ZnNiSi/ZnNi and CCC/ZnNiSi/ZnNi, respectively. Salt spray test indicated that after 48 h, surface of ZnNi and ZnNiSi was covered by white rust, whereas no white rust was observed on surface of CCC/ZnNiSi/ZnNi. After 600 h, there were red rust spots (1% surface coverage) on surface of Zn-Ni, whereas only white rust was observed on both ZnNiSi/ZnNi (100% surface coverage) and CCC/ZnNiSi/ZnNi (10% surface coverage).
Originality/value
Multilayer coating enhanced significantly the corrosion protection for steel, as compared to the single-layer coating.

Abstract
As a coastal emerging country, export-led marine economy has been the development model of Vietnam over the past decades since The Renovation 1986. Given the rise of globalization, regional economic integration and logistics enhancement have been identified as key engines for economic sustainability by Vietnamese government. Nevertheless, little sectoral and sub-sectoral evidence has been given for the platform shaped by policies relevant to export, logistics performance and regional economic integration. The paper employs the trade gravity model to study the relationship between seafood export, logistics performance and regional economic integration in the case of Vietnam. Sectoral and sub-sectoral trade gravity models are employed. Logistics performance from the exporter-side and importer-side is included in the estimations. Membership to effective regional trade agreements of Vietnam are proxies for regional economic integration. Zero trade issue is resolved by the Pooled Ordinary Least Squares (POLS), Poisson Pseudo-Maximum Likelihood (PPML) and Heckman Sample Selection estimations, while endogeneity is tackled by the difference and system Generalized Method of Moments (GMM) models. Findings vary by estimation methods, data levels, product groups, and whether which side is considered. In addition, theoretical contributions and some seafood export-driving policy recommendations relevant to regional economic integration and logistics performance development are discussed.

Abstract
Purpose
One Commune One Product (OCOP) program, a rural economic development program in Vietnam, aims to empower local communities for sustainable social and economic welfare development, protect the environment and preserve tradition. This study aims to employ this program associated with tourism to support small family businesses in rural areas cost-effectively.
Design/methodology/approach
This study used the geographic location mapping method to design tourist routes that connect tourism resources with OCOP producers. A stakeholder approach was employed to identify suggested practical works that need to be implemented while developing this tourism initiative.
Findings
Four rural districts of Bac Giang Province, a northern province in Vietnam known as the place of various indigenous people live and traditional craft villages. Many cultural and historical tourist sites have been chosen as sample areas for this study. By using Google map, based on the Bac Giang Tourist Map and a list of recognized OCOP products in Bac Giang Province, main tourist sites (16 locations) and small family businesses (known as cooperatives and households) that have OCOP products (17 places) in the four districts have been identified. Four notable tourist routes have been formed to propose four thematic tours (two 1-day tours and two 2 days-1 night homestay tours). Suggestions for related stakeholders to ensure the sustainability of this initiative are provided.
Research limitations/implications
This study is supposed to be a model of promoting small family businesses through OCOP programs and tourism activities in a sustainable way in Vietnam. The outcome of this study is in line with the stakeholder theory emphasizing the systematic connection of various stakeholders such as employees, suppliers, local communities, government agencies and others towards complex business sustainability. The results of the study cannot conclude the small family businesses in Vietnam because it adopts geographic location mapping alone. Moreover, this study focused on OCOP programs only. Future research can use other methods of primary data collection, especially from tourists' perspectives. Data triangulation can be done to explore and verify the tourist routes that have been formed according to the four thematic tours proposed. Future research could also compare hotels managed by family businesses with non-family businesses.
Originality/value
This study is supposed to be a model of promoting small family businesses through OCOP programs and tourism activities in a sustainable way in Vietnam.

Abstract
Subject area
Decision-making seems simple, but, in reality, it is not an easy task to decide the cause for its profound result or consequence, leading to inevitable failures. Therefore, a leader must recognize whether there is something incorrect so as to avoid bad results. A good leader is a person who carefully reviews and analyzes aspects of a problem, knows the strengths and weaknesses of his organization and evaluates what the advantages or risks are. It cannot be denied that the appropriate options will reap many benefits to the business. For such important things, this paper will discuss the dilemma of Viettire, a tire distributor company in Vietnam. Accordingly, its CEO was worried about what strategic option he should adopt to approach the Myanmar market while ensuring a strategic fit to its company’s resources and capabilities and also to the overall market demands of the tire industry environment in both countries. However, with different ideas, the expansion strategies in this new market become controversial. The General Director and Founder of Viettire were wondering how Viettire could expand its existing business into Myanmar. To expand the company to new emerging market in Myanmar, Hoang Nguyen – CEO of Viettire – had conducted a strategic analysis of external environment factors to define the opportunities and threats when doing business in Myanmar by using Porter’s five forces model, S.W.O.T and competitive advantages analysis. The results indicated that Myanmar’s business environment is highly risky for foreign investors because of uncertain political, economic, social reforms in the process. Among three options, namely, exporting, licensing and wholly owned, however, Option 2 is illustrated as the best strategy for its dilemma.

Case overview
As for a market mechanism, what produces, how and for whom, is not the business’s demand but the consumer’s demand. The business sells only what the market needs, not what it has. In the period of increasingly competitive conditions, stabilizing and expanding markets are a prerequisite for survival. If stability is seen as a “defensive” way, expansion is a “defensive attack” like trying to hold on the “pie” that the market gives to itself. This strategic action is to strengthen regular, close relationships with existing customers and establish new customers. As a result, the potential market is transformed into a target market. Hence, decision-making of which market, which method is the issue that a leader has to think the choice to avoid risks. Mr Hung, Viettire’s co-owner, suggests that Myanmar should be taken into account as a company’s new entry, thus exploring this potential market to increase the company’s growth and profitability. In the progress, Viettire’s marketing team had been doing a thorough tire market investigation in Myanmar. It was concluded that this emerging country, especially Yangon City, was the most suitable for those who were willing to embark on an overseas investment expansion. They believe this was a good opportunity to gain market share compared with other entrants and competitive rivals; if Viettire hesitated to invest, others definitely had jumped in with a first-mover advantage. However, the CEO, Mr Hoang, was worried about what strategic option he should adopt to approach this new market while ensuring a strategic fit to its company’s resources and capabilities and also to the overall market demands of the tire industry environment in both countries.
Expected learning outcomes
Understand the basic decisions that firms contemplating foreign expansion must make: which markets to enter, when to enter those markets and at what scale. Recognize the current strategic decisions an organization is facing: positioning, portfolio and market expansion approach. Learn how to develop an effective strategic plan. Be familiar with different strategies for competing globally and their pros and cons. Evaluate various strategic options and decisions in accordance with a company’s resources and capabilities.

Abstract
Purpose
Drought and salinity intrusion aggravated by climate change threaten agricultural livelihoods in Viet Nan's Mekong Delta. In response, authorities have built water management infrastructure for irrigation and salinity protection. This study assessed the impact of one such project, the Ba Lai dam in Ben Tre province, on the livelihoods of aquaculture farmers.
Design/methodology/approach
This study uses the Sustainable Livelihoods Framework to assess the impact of the Ba Lai dam on the livelihood capitals of 18 farming households in four communes, located both upstream and downstream of the dam.
Findings
The authors find that, apart from some positive effects, the dam has also brought negative environmental consequences, such as increased water pollution. The authors also find that farmers have responded to the changes by adapting their livelihood practices.
Research limitations/implications
The samples were relatively small, encompassing four communes in Ben Tre province. On the other hand, this case study is instructive to the many ongoing infrastructure projects in the Vietnamese Mekong Delta.
Social implications
The project have caused an increase in water-related social conflict.
Originality/value
The case of the Ba Lai dam provides a cautionary example for infrastructure-based water management plans, both in Viet Nam and more broadly. The study suggests the need to strengthen community participation and prioritize impacts of farmers' capital assets when constructing water management infrastructure for climate change adaptation.

Abstract
Unsustainable logging and illegal logging for domestic and international trade and trafficking continue to lead to deforestation. It is crucial that Sustainable Development Goal 15 ‘Sustainably manage forests, combat desertification, halt and reverse land degradation, halt biodiversity loss’ is achieved to maintain the livelihoods of people and protect the planet. This is the case in Vietnam as well, where many people, including indigenous groups, rely on the forest for their survival. Drawing on semistructured interviews in Vietnam and a literature review, we investigate how the abuse of forest policies leads to human insecurity. From this, we propose solutions to (1) end unsustainable harvesting and illegal logging (SDG 15.7), (2) integrate the value of forests (culturally and economically) into national and local planning, the development process and poverty elimination strategies (SDG 15.9) and (3) improve the use of forest protection funding provided by international donors.

Abstract
Purpose
Given the important role of frugal innovation for firms in the developing and emerging countries, the purpose of this paper is to investigate the effect of transformational leadership (TL) on frugal innovation through the mediating roles of tacit and explicit knowledge sharing.
Design/methodology/approach
The paper used a quantitative research method and structural equation modeling to test the relationship among the latent factors based on a sample of 339 participants from 120 Vietnamese firms.
Findings
Findings reveal the significant impacts of TL on aspects of frugal innovation, namely, frugal functionality, frugal cost and frugal ecosystem. Moreover, the paper highlights the mediating roles of tacit and explicit knowledge sharing (KS) in the relationship between TL and frugal innovation in terms of frugal functionality and frugal cost.
Research limitations/implications
To bring a deeper understanding of the benefits and important role of knowledge resources, future research should investigate the potential mediating mechanisms of knowledge management processes in the relationship between specific leadership styles and frugal innovation.
Practical implications
The paper provides a valuable understanding and novel approach for managers and directors of firms in developing and emerging countries to improve their firms’ frugal innovation capability through leadership practice and knowledge resources.
Originality/value
This study contributes to bridging research gaps in the literature and advances the insights of how TL directly and indirectly fosters frugal innovation via mediating roles of tacit and explicit KS.

Abstract
Purpose
Due to the vital role of innovation for firms to respond effectively to the rapid changes of business environment, the purpose of this study is to explore the influence of transformational leadership (TL) on innovation capability of firms via mediating role of knowledge management capability (KMC). It attempts to deepen insight on the moderating mechanism of innovation culture (IC) in enhancing the effects of KMC on two specific aspects of innovation capability namely product and process innovation.
Design/methodology/approach
The paper utilized structural equation modeling (SEM) and cross-sectional design to test hypotheses in the proposed research model using data collected from 339 participants in 75 manufacturing and service firms in China.
Findings
The findings indicate that TL directly or indirectly affect firm's innovation via mediating role of KMC. The findings highlight that influences of KMC on aspects of innovation capability are different and depended on the degree of innovative climate in an organization.
Research limitations/implications
Future research should examine the mediating mechanisms of knowledge acquisition, knowledge sharing and knowledge application to provide deeper insight on specific roles of knowledge management's constituents in linking TL and innovation capability.
Originality/value
This study contributes to bridging research gaps in the literature and advancing the insights of how TL directly and indirectly fosters product and process innovation via mediating roles of KMC. By investigating moderating role of IC, this study has provided the valuable initiatives and integration view of a new mechanism to foster specific dimensions of innovation capability of firms in developing and emerging market.

Abstract
Purpose
The purpose of this paper is to investigate the mediating roles of knowledge sharing behaviors (knowledge collecting and donating) in linking the relationship between high-commitment human resource management (HRM)practices and specific aspects of innovation capability, namely, exploitative and exploratory innovation.
Design/methodology/approach
The paper is based on quantitative approach and structural equation modeling to examine the correlation among the latent constructs based on the survey data collected from 281 participants in 95 Chinese firms.
Findings
The findings of this study support the mediating role of knowledge sharing (KS) behaviors in the relationship between HRM practices and aspects of innovation capability. It highlights the important role of knowledge donating and indicates that the effect of knowledge donating is more significant than that of knowledge collecting on exploitative and exploratory innovation.
Research limitations/implications
Future research should investigate the impact of high-commitment HRM practices on innovation capability under the moderating effects of organizational variables to bring better understanding on the relationship among them.
Originality/value
The paper significantly contributes to increasing knowledge and insights on the correlation between high-commitment HRM practices and specific forms of innovation. The understanding on mediating role of KS contribute to advancing the body of knowledge of HRM and innovation theory.

Abstract
Purpose
This article traces the transformation of hát bội, a form of traditional opera in Southern Vietnam, from its primary role as entertainment into a religious activity after the Reform (Đổi Mới) were enacted in 1986.
Design/methodology/approach
This research is based on ethnological fieldwork complemented by a review of historical documents and of the available literature on hát bội, cultural policies and on data collected from interviews with artists and spectators at the festival at the shrine to the Lady of the Realm.
Findings
Before 1986, hát bội was performed either as a stand-alone entertainment during the fair portion of community festivals or as part of religious ceremonies. The Reform and the accompanying relaxation of state control over religion and culture promoted the resurgence of popular religious fairs across the nation. New opportunities for hát bội to revive opened, artists left state-sponsored troupes to join private companies that catered to religious festivals. But almost exclusive involvement in religious rites has led to artistic stasis for private hát bội troupes.
Originality/value
This research constitutes novel insights of how the Reform in Vietnam affects the transformation of a traditional performance form.
