Abstract

Purpose

COVID-19 hits every country’s health-care system and economy. There is a trend toward using automation technology in response to the COVID-19 crisis not only in developed countries but also in those with lower levels of technology development. However, current studies mainly focus on the world level, and only a few ones report deployments at the country level. The purpose of this paper is to investigate the use of automation solutions in Vietnam with locally available materials mainly in the first wave from January to July 2020.

Design/methodology/approach

The authors collected COVID-related automation solutions during the first wave of COVID-19 in Vietnam from January to July 2020 through a search process. The analysis and insights of a panel consisting of various disciplines (i.e. academia, health care, government, entrepreneur and media) aim at providing a clear picture of how and to what extent these solutions have been deployed.

Findings

The authors found seven groups of solutions from low to high research and development (R&D) levels deployed across the country with various funding sources. Low R&D solutions were widely spread owing to simplicity and affordability. High R&D solutions were mainly deployed in big cities. Most of the solutions were deployed during the first phases when international supply chains were limited with a significant contribution of the media. Higher R&D solutions have opportunities to be deployed in the reopening phase. However, challenges can be listed as limited interdisciplinary research teams, market demand, the local supporting industry, end-user validation and social-ethical issues.

Originality/value

To the authors’ best knowledge, this is the first study analyzing the use of automation technology in response to COVID-19 in Vietnam and also in a country in Southeast Asia. Lessons learned from these current deployments are useful for future emerging infectious diseases. The reality of Vietnam’s automation solutions in response to COVID-19 might be a reference for other developing countries with similar social-economic circumstances and contributes to the global picture of how different countries adopt technology to combat COVID-19.

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

The purpose of this paper is to present a low-cost, highly mobile system for performing street-level imaging. Street-level imaging and geo-location-based services are rapidly growing in both popularity and coverage. Google Street View and Bing StreetSide are two of the free, online services which allow users to search location-based information on interactive maps. In addition, these services also provide software developers and researchers a rich source of street-level images for different purposes – from identifying traffic routes to augmented reality applications. Currently, coverage for Street View and StreetSide is limited to more affluent Western countries with sparse coverage throughout south-east Asia and Africa. In this paper, we present a low-cost system to perform street-level imaging targeted towards the congested, motorcycle-dominant south-east Asian countries. The proposed system uses a catadioptric imaging system to capture 360-degree panoramic images which are geo-located using an on-board GPS. The system is mounted on the back of a motorcycle to provide maximum mobility and access to narrow roads. An innovative backwards remapping technique for flattening the images is discussed along with some results from the first 150 km which have been captured from Southern Vietnam.

Design/methodology/approach

The design was a low-cost prototype design using low-cost off-the-shelf hardware with custom software and assembly to facilitate functionality.

Findings

The system was shown to work well as a low-cost omnidirectional mapping solution targeted toward sea-of-motorbike road conditions.

Research limitations/implications

Some of the pictures returned by the system were unclear. These could be improved by having artificial lighting (currently only ambient light is used), a gyroscope-stabilised imaging platform and a higher resolution camera.

Originality/value

This paper discusses a design which facilitates low-cost, street-level imaging for a sea-of-motorcycle environment. The system uses a catadioptric imaging approach to give a wide field of view without excessive image storage requirements using dozens of cameras.

Abstract

Purpose

This paper aims to provide a deep understanding of rural household livelihoods in the Mekong Delta and to explore how they can cope with climate stressors at the ground level.

Design/methodology/approach

The paper employs the sustainable livelihood framework at a household and also an individual scale. The general data obtained from a survey of 2,100 households provide an overview of their livelihoods. Qualitative and quantitative methods were adopted, as case studies, to comprehensively assess 100 households in one commune affected by annual floods and an additional 100 households in another commune affected by sea level rises. Livelihood profile analysis is beneficial to identify specific livelihood change patterns that have taken place in these specific cases.

Findings

There are four types of livelihood adaptation to climate stressors: (1) change of structure of agricultural systems, (2) change of employment locations, (3) resettlement with strong impact on livelihoods and (4) out-migration. The household livelihood resources and the local economic structures have significant roles in driving adaptive solutions.

Research limitations/implications

This paper provides detailed profiles of the livelihood change considered as passive adaptation of smallholders in the Mekong Delta.

Originality/value

It contributes to the knowledge of rural households in multiple aspects with regard to how they cope with climate change via reflection on their livelihoods.

Abstract

Purpose

The purpose of this paper is to review both international and domestic (i.e. Vietnamese language) journal articles and graduate theses and dissertations on educational leadership in Vietnam. The review addresses two specific goals: first, to describe and critically assess the nature of the formal knowledge base on principal leadership in Vietnam, second, to synthesize findings from the existing literature on principal leadership in Vietnam.

Design/methodology/approach

The paper employed a method for conducting systematic reviews of research. The authors conducted a detailed, exhaustive search for international and “local” papers from Vietnam, yielding 120 research sources. Information from these papers was extracted and evaluated prior to analysis. Data analysis included both quantitative description of the “review database” as well as critical synthesis of substantive findings.

Findings

The review supports and extends an earlier review which found that the practice of educational leadership in Vietnam remains largely “invisible” to the international community of scholars. The review also yielded a highly critical assessment of research perspectives and methods used in the “local” Vietnamese studies which comprised the bulk of the authors’ database. Synthesis of substantive findings highlighted the manner by which organizational, political, and socio-cultural forces in the Vietnamese context shapes the practice of school leadership.

Research limitations/implications

First, qualitative studies are recommended that seek to describe, in-depth, the enactment of leadership in the Vietnamese context. Second, broad-scale surveys of characteristics, attitudes, and beliefs of school leaders across Vietnam are warranted. Third, the authors encourage graduate students and scholars studying school leadership in Vietnam to undertake a new generation of theory-informed studies that connect with the global literature.

Practical implications

Due to the relatively weak nature of the existing knowledge base, the authors were unable to identify specific implications for leadership practice. However, practical implications are identified for developing the research capacity needed to improve research quality in Vietnam’s universities.

Originality/value

This review is the first systematic review of educational leadership and management conducted of the Vietnamese literature. Moreover, the authors suggest that the review is original in its comprehensive coverage of both the local and international literature on educational leadership in Vietnam.

Abstract

Microfinance plays a crucial role to reduce the poverty in developing countries. For that reason, the effectiveness of microfinance institutions (MFIs) is widely investigated in the literature. This study examines the levels of efficiency of MFIs in Vietnam and their determinants. The research, then, evaluates the relationship between MFIs’ efficiency and poverty reduction. Data are mainly taken from the MIX market website and other empirical researches. Regarding the methodology, two-stage data envelopment analysis (DEA) is used to estimate MFIs’ efficiency scores in Vietnam and their determinants, while meta-analysis and statistic descriptions are employed to examine the relationship between MFIs’ efficiency and poverty reduction. The findings show that technical efficiency (TE) of MFIs in Vietnam is considerably high with the average TE score and efficiency of scale being 85.5% and 94.7%, respectively. Size, age, outreach, and market target of MFIs are found not to be determinants of efficiency, while capital structure is. Also, many researches confirm the impact of MFIs’ efficiency to poverty reduction. However, the relationship is different between countries because of particular characteristics and operational mechanisms.

Abstract

Purpose

The purpose of this paper is to trace the way in which a popular ritual became one of Vietnam’s most important festivals, elevated as a celebration of national heroism and charts its gradual transformation in modern society.

Design/methodology/approach

This research focuses on the combination of a fertility rite and narratives of St Gióng based on nationalism or heroism created a special festival reflecting many traditional cultural characteristics of Vietnam and the Việt people and the transformation of St Gióng from a mythological to a national symbol of heroism in anti-invader history was recorded in texts.

Findings

The paper casts light on the mythologization and historicization of St Gióng in Vietnam’s particular historical context by decoding the Gióng symbol as a core element of the folktales and myths about St Gióng to understand the formation and development of St Gióng in the cultural history of Vietnam.

Research limitations/implications

The paper is not exploring the Gióng symbol within a larger cultural context of nationalism and ethnosymbolic approach in a comparison of national symbolism and heroism.

Practical implications

The paper includes implications for advised scholars to conduct further exploration of the symbol and myth of not only St Gióng in Vietnam but also Kubera in India and Vaisravana in China to connect Kubera, Vaisravana and St Gióng under the connection of literal myth and heroic symbol.

Social implications

The paper shows how processes of historicizing myth and mythologizing history are important features of Vietnamese socio-historical research.

Originality/value

The paper shows how a fertility rite became a historical festival and the figure of St Gióng became a symbol of patriotic heroism.

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

The purpose of this paper is to present a fully automated numerical tool for computing the effective permeability of porous media from digital images which come from the modern imagery technique.

Design/methodology/approach

The permeability is obtained by the homogenization process applied to a periodic rigid solid in which the fluid flow is described by the Stokes equations. The unit cell problem is solved by using the Fast Fourier Transform (FFT) algorithm, well adapted for the microstructures defined by voxels.

Findings

Various 3-D examples are considered to show the capacity of the method. First, the case of flow through regular arrays of aligned cylinders or spheres are considered as benchmark problems. Next, the method is applied to some more complex and realistic porous solids obtained with assemblies of overlapping spherical pores having identical or different radii, regularly or randomly distributed within the unit cell.

Originality/value

The use of FFT allows the resolution of high-dimension problems and open various possibilities for computing the permeability of porous microstructures coming from X-ray microtomography.

Abstract

Purpose

A review of literature has documented that accessing formal credit and other banking services has always been a crucial challenge for small and medium-sized enterprises (SMEs). The alternative, therefore, tends to be informal channels. However, the credit constraint vis-à-vis informal channel link does not appear to be well documented in the literature. This study aims to investigate whether credit constraints significantly affect the probability of accessing informal credit, as well as the credit values of Vietnamese SMEs.

Design/methodology/approach

This study uses a trinary approach and correlated random-effects Probit and Tobit techniques to avoid the incidental coefficients problem.

Findings

The results suggest that relative to unconstrained and partially constrained firms, fully constrained firms tend to be more active in the informal credit markets, shown by their higher probability of informal credit access and larger credit values.

Originality/value

To the best of authors’ knowledge, this is the first study on Vietnam that takes a different approach to credit constraints and examines their impact on informal credit access. Policy implications arise and are discussed.
