Abstract
Purpose
This paper aims to examine the management status quo of archaeological heritage in Vietnam seen in the case of Vuon Chuoi, a complex of Bronze Age sites located in Central Hanoi, which has been believed to be Hanoi’s first human settlement. Like other archaeological sites located in urban areas, this site has been under threat of destruction caused by land encroachment pressure. Although researchers have long waged a campaign for preservation, the dissensus among key stakeholders and the dispute over responsibility have left this site at the heart of an interminable polemic over legislation.
Design/methodology/approach
This research utilises a qualitative approach, and the primary data were collected throughout multiple field trips in 2019 and 2020. Several open-ended interviews were conducted with various state and nonstate actors involved in the Vuon Chuoi Complex’s management process. The discussion was also supported by analysing related legal documents retrieved from national archives and official online directories.
Findings
This paper dissects the current legislative and administrative framework applied in governing heritage in general and archaeological sites in Vietnam, in particular. The results indicate that existing flaws in Vietnam’s legal system are detectable, and the unsystematic organisation has led to deferment of the decision-making processes. Also, there is an apparent difference found in the attitude of the bodies in charge toward the treatment of listed and unlisted sites.
Originality/value
This research outlines that in the wake of urbanisation and industrialisation in Vietnam, a consensus among key stakeholders and an inclusive legal system are required to help preserve archaeological sites in urgent need of attention. Although several Vietnamese laws and regulations have been put into practice, they have shown critical barriers and gaps in conserving Vietnamese cultural heritage.

Abstract
Purpose
The purpose of this paper is to identify the leverage points in the Vietnamese coffee supply chain (SC) that would be used for increasing competitive advantages of the product.
Design/methodology/approach
A sequential approach by combining two established modelling techniques (causal loop diagram and Bayesian belief networks) was applied to identify the leverage points in the Vietnamese coffee SC for increasing the competitive advantages of the product. Data for the study were collected from a series of workshops and in-depth interviews with numerous relevant stakeholders of the coffee industry in the central highland of Vietnam.
Findings
The systems’ archetypes were developed and a sensitivity analysis was conducted to identify potential factors that can increase the competitive advantages of coffee production. The results indicate that higher investment in all elements of the coffee SC will lead to an enhanced competitive advantage.
Originality/value
Supply chain management (SCM) has become a potentially valuable method for improving competitive advantages, as competition is no longer only between organizations but also among SCs. Therefore, this research focus on enhancing the competitive advantages of production via SCM.

Abstract
Purpose
This paper attempts to develop a simple, static model of tax administration that is capable of explaining the widespread collusive petty tax administration corruption observed in developing countries.
Design/methodology/approach
This paper utilizes a positivist research framework and adopts a theoretical method of analysis, although secondary data will also be mentioned to support theoretical arguments whenever it is appropriate to do so.
Findings
A high rate of collusive tax corruption is inevitable in developing countries.
Research limitations/implications
The model is static and needs to be extended into a dynamic model.
Practical implications
Traditional enforcement tools such as higher audits or a higher penalty regime against tax evasion do not work. Tax simplification can lessen the incidence of tax corruption.
Social implications
Fighting tax corruption requires significant changes in the attitudes of taxpayers and tax auditors.
Originality/value
This paper combines the literature on Kantian economics and tax compliance in an innovative fashion.

Abstract
Purpose
The purpose of this paper is to propose an approach, which is easy to implement, for estimating the thickness of the air layer that may separate metallic parts in some aeronautical assemblies, by using the eddy current method.
Design/methodology/approach
Based on an experimental study of the coupling of a magnetic cup core coil sensor with a metallic layered structure (consisting of first metal layer/air layer/second metal layer), which is confirmed by finite element modelling simulations, an inversion technique relying on a polynomial forward model of the coupling is proposed to estimate the air layer thickness. The least squares and the nonnegative least squares algorithms are applied and analysed to obtain the estimation results.
Findings
The choice of an appropriate inversion technique to optimize the estimation results is dependent on the signal-to-noise ratio of measured data. The obtained estimation error is smaller than a few percent, for both simulated and experimental data. The proposed approach can be used to estimate both the air layer thickness and the second metal layer thickness simultaneously/separately.
Originality/value
This model-based approach is easy to implement and available to all types of eddy current sensors.

Abstract
Purpose
In the wine industry, maintaining superior quality standards is crucial to meet the expectations of both producers and consumers. Traditional approaches to assessing wine quality involve labor-intensive processes and rely on the expertise of connoisseurs proficient in identifying taste profiles and key quality factors. In this research, we introduce an innovative and efficient approach centered on the analysis of volatile organic compounds (VOCs) signals using an electronic nose, thereby empowering nonexperts to accurately assess wine quality.
Design/methodology/approach
To devise an optimal algorithm for this purpose, we conducted four computational experiments, culminating in the development of a specialized deep learning network. This network seamlessly integrates 1D-convolutional and long-short-term memory layers, tailor-made for the intricate task at hand. Rigorous validation ensued, employing a leave-one-out cross-validation methodology to scrutinize the efficacy of our design.
Findings
The outcomes of these e-demonstrates were subjected to meticulous evaluation and analysis, which unequivocally demonstrate that our proposed architecture consistently attains promising recognition accuracies, ranging impressively from 87.8% to an astonishing 99.41%. All this is achieved within a remarkably brief timeframe of a mere 4 seconds. These compelling findings have far-reaching implications, promising to revolutionize the assessment and tracking of wine quality, ultimately affording substantial benefits to the wine industry and all its stakeholders, with a particular focus on the critical aspect of VOCs signal analysis.
Originality/value

Abstract
Purpose
Australian sales of hyperpalatable beverages (HPB) (a term used to describe naturally or artificially sweet beverages) have followed a consistent upward trend since 2000. The purpose of this paper is to examine HPB brand placements in the top 20 annual highest grossing movies in Australia in 2010-2014.
Design/methodology/approach
A content analysis was undertaken on the 20 highest grossing movies annually from 2010 to 2014. Movies were analysed according to the prevalence and portrayal of branded beverages.
Findings
In total, 35 per cent of movies contained an HPB brand placement. Movies were more likely to be classified M, MA15+, R/R18+, and categorised as comedy, or action/adventure genre. Soft drinks were the most prevalent category (60.9 per cent), and Coca Cola Company manufactured 40.6 per cent of the brands that were embedded throughout the movies.
Originality/value
This study revealed some of industry’s non-direct marketing strategies through HPB placement in movies. Findings suggest that further scrutiny is needed of the relatively underresearched medium of beverage advertising.

Abstract
Purpose
This paper aims to explore how research and development (R&D) scientists and engineers can contribute to sustainability initiatives in their organisations.
Design/methodology/approach
This paper uses a critical case study methodology, focussed on a large Vietnamese company in which business leaders sought to engage R&D scientists and engineers in sustainability initiatives focussed on eco-innovation and eco-efficiency. Bourdieu’s theoretical lens of habitus, capitals and field facilitates a relational analysis of the findings.
Findings
While R&D scientists and engineers adapted well to early changes aligned with eco-innovation, they struggled to engage with sustainability initiatives in the case firm. This study explains adaptions and constraints as scientists and engineers’ professional habitus and capitals, and their broader organisational field.
Practical implications
This paper provides insight into how organisations might integrate professional acculturation and appropriate facilitators to promote the additional contribution of scientists and engineers to sustainability initiatives in the context of an organisation.
Social implications
Although eco-innovation and eco-efficiency are only potential dimensions of comprehensive organisational sustainability reform, this research provides insight into how engaging scientists and engineers with a broader social sustainability agenda might be advanced.
Originality/value
The study addresses calls for empirical insights into ways that scientists and engineers can commit to organisational sustainability practices based on the configurations of habitus, capital and organisational field.

Abstract
The community college model is evolving in the Socialist Republic of Viet Nam. During June 2009, 11 of the 12 existing higher education institutions with “community college” in their official name were examined utilizing a qualitative multiple-case study approach. Data were collected in the field from June 1 to 23, 2009, while making visits to each of the 11 colleges, the Ministry of Education and Training (MOET), and the Vietnam Association of Community Colleges (VACC). Five data collection techniques were utilized to examine the bounded system: (a) semi-structured interviews, (b) survey of the college rectors, VACC informant and MOET informant, (c) participant observation with field notes, (d) document review, and (e) photographs taken during each site visit. After the field study stage, e-mail communication with the study informants between August 2009 and March 2010 clarified questions and developed a deeper level of understanding of the Vietnamese community college model. Results of the study (Epperson, 2010) indicate that although legislation does not exist to permanently establish the higher education institutions named community colleges, a community college model does exist and is in a state of evolution. The model can be defined by a set of core characteristics which emerged from the data. Five themes were particularly prominent: (a) public higher education institutions with community ownership at the provincial or city level, in conjunction with MOET oversight for academic matters; (b) multidisciplinary programs designed to meet the unique needs of the community; (c) multi-level certificates and diplomas conferred up through the college level (three year) of higher education and articulation agreements with universities enable students to earn a university bachelor's degree; (d) domestic and international partnerships are actively sought to develop social capital; (e) scientific and technological research based on community needs as required in the 2005 Education Law.

Abstract
“The world needs science, science needs women” is the message given by UNESCO in the program for the development of women in science” (UNESCO, 2017). In Vietnam, women’s participation and achievements in scientific research is considered a great and important resource for industrialization and modernization. Even so, are there gender differences in scientific achievement in the social science research institutes in Vietnam? What factors influence the scientific achievement of female social researchers? The answers will be based on data from a 2017 survey with a sample of 756 researchers, of which 77.6% were female. The survey was conducted by the Vietnam Academy of Social Sciences, a leading, ministry-level national center for the social sciences in Vietnam. This chapter analyzed the scientific achievements of researchers through their position as principal investigators of research projects and their publications, and factors that may impact this. Bivariate and multivariate analyses of factors that may affect the scientific achievement of researchers found that gender differences in academic achievement in the social sciences in Vietnam was still prevalent. Female researchers’ scientific achievements were lower than those of their male counterparts. The contribution to science of Vietnamese female researchers was limited by many different factors; the most important were the academic rank of the researchers and gender stereotype that considered housework the responsibility of women.
