Abstract

Purpose

This paper aims mainly at introducing applied statisticians and econometricians to the current research methodology with non-Euclidean data sets. Specifically, it provides the basis and rationale for statistics in Wasserstein space, where the metric on probability measures is taken as a Wasserstein metric arising from optimal transport theory.

Design/methodology/approach

The authors spell out the basis and rationale for using Wasserstein metrics on the data space of (random) probability measures.

Findings

In elaborating the new statistical analysis of non-Euclidean data sets, the paper illustrates the generalization of traditional aspects of statistical inference following Frechet's program.

Originality/value

Besides the elaboration of research methodology for a new data analysis, the paper discusses the applications of Wasserstein metrics to the robustness of financial risk measures.

Abstract

Purpose

This research aims to specialise in the investigation of risk management for service-oriented manufacturing supply chains via two stages, highlighting its differences from manufacturing. The research article is commenced by executing an encyclopedic review of earlier research to ascertain the distinctive traits of service-oriented manufacturing supply chains and identify prevalent risks. Secondly, an empirical study in the construction field, amongst the industry hardest struck in the mist of the COVID-19 epidemic, is conducted to thoroughly inspect the resonant effect of these risks on service-oriented manufacturing supply chain performance.

Design/methodology/approach

In this study, to validate the resonant effect mechanism, a thorough assessment is undertaken by juxtaposing theoretical model to a newly constructed comparative model that encompasses the single effects of risks on supply chain performance.

Findings

63% variance of service-oriented manufacturing supply chain performance was showcased by the resonant effect model, compared with 46.3% in the comparative model. Moreover, each risk exerts a more glaringly significant impact on supply chain performance, asserting the mechanism of the resonant influence. Another noteworthy result involves the demand risk possessing a low effect on supply chain performance, thus emphasising the superiority of service-oriented manufacturing supply chains.

Research limitations/implications

Future research endeavours should hinge on the optimal “resonant” model explosion, thereby foreseeing and alleviating worst-case scenarios to guarantee the robustness and resilience of supply chain networks.

Practical implications

Indubitably, reducing the intensity of the resonant effect revolves around lowering the coefficient of “a,” thereby restricting/eliminating the link among risks. Therefore, the suggested resonant impact model might thus serve as “a road map”. In light of the aforementioned considerations, it is advisable that supply chain executives employ supply chain management tactics namely avoidance, prediction, and postponement, but only after meticulous consideration the costs and benefits of adopting such strategies.

Originality/value

The service-oriented manufacturing supply chain features and advantages have been analysed and explained throughout the article. The data gathered during the COVID-19 pandemic is a captivating and topical point of this paper.

Abstract

Purpose

Based on the ability, motivation and opportunity (AMO) theory, this study aims to investigate the role of digital human resources management (digital-HRM) practices in influencing hotel employee behaviors, especially their adoption of work-at-home (WAH).

Design/methodology/approach

The study was conducted in two stages in hotels in Vietnam. Stage 1 used a mixed method to develop an instrument to measure digital-HRM practices. In Stage 2, through a survey of 303 respondents, the research investigated digital-HRM practices’ additive and interactive effects on WAH.

Findings

The study shows that digital-HRM comprised five factors. Except for digital recruitment, the other digital-HRM practices significantly affected WAH. In addition, the research suggests that digital training and employee involvement should be combined to enhance employee willingness for WAH.

Research limitations/implications

Drawing on the AMO theory, this study constructs a digital-HRM measurement scale to study the antecedents and consequences of these practices to improve employees’ digital work efficiency. In addition, through both additive and combinative (a two-way interaction) models, the study enhances the HRM and hotel management theory by understanding why digital-HRM practices are essential to boost employees’ digital competencies to adopt remote working.

Practical implications

By investigating the role of digital-HRM practices in improving employees’ adoption of WAH, this study provides empirical implications for hotels to manage digital-HRM practices better and thus makes remote working effective.

Originality/value

The existing literature reveals the lack of a deep understanding of how HRM practices can promote digital devices and services and their influence on employee behaviors, especially in the hotel sector. To the best of the authors’ knowledge, this study is unique in extending the AMO theory into the digital context to illuminate components of digital-HRM practices and clarify how digitalizing HRM practices can motivate hotel employees to accept WAH.

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

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

Using a substantial sample of U.S.-listed firms’ Seasoned Equity Offerings (SEOs) spanning the period from 2012 to 2017, we examine the relationship between hierarchical complexity and the selection of SEO methods.

Design/methodology/approach

We employ multinomial logistic regression to examine the influence of hierarchical complexity on the choice among various SEO techniques. To strengthen the robustness of our results, we employ a two-stage-least-squares (2SLS) analysis and utilize propensity score matching to address potential endogeneity issues and mitigate self-selection bias, respectively.

Findings

The research indicates that companies characterized by high levels of hierarchical complexity tend to steer clear of accelerated offerings but exhibit a preference for rights offerings over firm commitment offerings. This tendency is plausibly attributed to the impact of hierarchical complexity, which diminishes information transparency and heightens information asymmetry. Furthermore, the study highlights a negative association between hierarchical complexity and firm value following SEOs.

Originality/value

While an expanding body of evidence establishes a connection between hierarchical complexity and various firm- or market-specific activities, to the best of our knowledge, there are no specific empirical studies that have investigated how hierarchical complexity impacts equity offering strategies. Building on the established correlation in previous research between hierarchical complexity, information transparency, and asymmetric information, and recognizing the critical role of information in the selection of SEO methods, our study reveals that hierarchical complexity may diminish information transparency, heighten information asymmetry, and hinder outside investors from fully grasping a firm’s actions and outcomes. Consequently, this influence extends to the methods of offerings chosen by listed companies.

Abstract

Purpose

The Vietnam construction industry has considerably developed since 1986 as a result of “Doi Moi” or all-round renovation process. However, despite the pace of economic reforms, a number of challenges continue to plague the construction industry. The purpose of this paper is to revisit the factors causing construction project failure in Vietnam. Some of the selected best practices from Brazil, Russia, India, China and South Africa (BRICS) and China, Indonesia, Vietnam, Egypt, Turkey, South Africa (CIVETS) are discussed.

Design/methodology/approach

Using a mixed method approach, data were collected from construction stakeholders in Vietnam using a postal survey questionnaire and semi-structured interviews. The quantitative data were subjected to descriptive statistics using ranking and frequencies analysis, and qualitative data employed content analysis.

Findings

Despite the lack of systematic approach to managing projects risks, there is a high level of acknowledgement regarding the importance of risk management practices. The highly ranked critical factors still causing construction project failure in Vietnam are: disregard of the significance of project planning process and project planning; lack of experience in executing complicated project; poor design capacity and frequent design changes; lack of knowledge and ability in managing construction projects; lack of financial capacity of owner; poor performance of contractors; lack of a systematic approach to managing the project and entire organisation; corruption and bribery in construction projects; the delays in payment; and economic volatility and high inflation.

Practical implications

The identified and revisited project failure factors could be used as a “road map” for the revaluation, and development of appropriate project management practices.

Originality/value

The construction sector has undergone through significant structural changes following “Doi Moi”. This study provides the opportunity to realign the strategies for addressing project failure factors and learning from comparative studies in BRICS and CIVETS countries.

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

Purpose

Tourism is one of the most notable features of the contemporary globalised world. The tourism industry is becoming increasingly vital to the economy of many developing and developed countries around the globe. The demand of the tourism industry has posed a challenge for tourism training providers to move towards a more responsive and internationalised curriculum to enhance work readiness for tourism graduates who are expected to work with an increased number of international tourists. The purpose of this paper is analyse whether and how internationalisation has been implemented in the tourism training programmes across six institutions in Vietnam.

Design/methodology/approach

The research deployed case studies as research strategy with interviews and document analysis as two instruments of data collection.

Findings

The major findings show that even though the tourism industry demands graduates to possess global competency, knowledge and skills, the curriculum does not prioritise the internationalisation dimensions and the faculty members are not facilitated to be internationally active in their roles. Overall, internationalisation is still fragmented and ad hoc in these institutions even though the private institutions in this research appear to be more responsive to the trend of internationalisation in education than their public counterparts.

Research limitations/implications

The paper provides recommendations on how to effectively embed internationalisation components into local tourism training programs in Vietnam.

Originality/value

The research bridges the gap in the literature on internationalisation of the local tourism programme in non-English-speaking countries.

Abstract

Purpose

The growing awareness of climate risks associated with food safety issues has drawn the attention of stakeholders urging the food industry to carry out a sustainable food safety management system (FSMS). This study aims to investigate whether the critical success factors (CSFs) of sustainable FSMS can contribute to achieving climate neutrality, and how the adoption of FSMS 4.0 supported by the Industry Revolution 4.0 (IR 4.0) technologies moderates the impact of the CSFs on achieving climate neutrality.

Design/methodology/approach

Survey data from 255 food production firms in China and Vietnam were utilised for the empirical analysis. The research hypotheses were examined using structural equations modelling (SEM) with route analysis and bootstrapping techniques.

Findings

The results show that top management support, human resource management, infrastructure and integration appear as the significant CSFs that directly impact food production firms in achieving climate neutrality. Moreover, the results demonstrate that the adoption of FSMS 4.0 integrated with the three components (ecosystems, quality standards and robustness) significantly moderates the impact of the CSFs on achieving climate neutrality with lower inputs in human resources, infrastructure investment, integration and external assistance, and higher inputs in strengthening food safety administration.

Originality/value

This study provides empirical findings that fill the research gap in understanding the relationship between climate neutrality and the CSFs of sustainable FSMS while considering the moderating effects of the FSMS 4.0 components. The results provide theoretical and practical insights into how the food production sector can utilise IR 4.0 to attain sustainable FSMS for achieving climate neutrality.
