The paper aims to develop a method for improving the accuracy of smart sensors (deemed as digital measuring instruments) by organizing combined measurements and processing their results by the parametric adjustment method at heterogeneous dispersion of the random error of the applied regression model.

When carrying out combined measurements, the problem of joint processing of measurement results of functionally related quantities must be solved. The function type can be known in advance or obtained experimentally. The number of combined measurements exceeds the number of unknown measured quantities. The redundant measurements can improve the accuracy of estimates of measured values but lead to inconsistency of the measurement results. The problem of inconsistency is solved by the parametric adjustment method, which is rather widely used mainly in the field of geodetic measurements, wherein the parametric equations are linear and the measured quantities are additive.

The proposed method allows to reduce the uncertainty of type B of a measurement result, caused by the maximum permissible error of a digital measuring instrument, by 1.2–4 times in comparison with the direct estimation method.

A compact description of the parametric adjustment method in matrix form is given. Recommendations are given on shaping a sensitivity matrix of functions for the proposed method. The geometric interpretation of the proposed method is considered. The results of the proposed method experimental testing are given when evaluating resistance values.

This essay examines a common assertion among middle-class shoppers in Ho Chi Minh City, Vietnam, that place of manufacture, rather than brand markers, largely determines the quality of goods. For shoppers in Ho Chi Minh City, unity of place, people, raw materials, and trade secrets at the source – a corporation’s home country – is essential to the production of high quality goods. This stands in contrast to the brand logic through which corporations outsource their production presumably without compromising product quality. By privileging production sites over brands, shoppers in Ho Chi Minh City interpret the recent increase of famous foreign brand name goods in Vietnam as an increase of domestic, rather than foreign goods.

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.

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.

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.

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.

The project have caused an increase in water-related social conflict.

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.

This chapter focuses on the potential of urban agriculture to support progress in SDG targets 2.1, 2.2, 2.3, and 2.4 in Ho Chi Minh City (HCMC), Vietnam. The chapter integrates findings from the British Council-funded project, ‘Urban Resilience from Agriculture through Highly Automated Vertical Farming in the UK and Vietnam’, undertaken in collaboration with Middlesex University, Van Lang University, and local agricultural stakeholders in HCMC. Food security in the city faces multiple challenges ranging from significant in-migration, decreasing area of cultivated land, the impact of the Covid-19 pandemic that continues to depress the economy and disrupt food supply chains, and climate change impacts affecting the environment and people throughout the city. HCMC accommodates a substantial agricultural sector, which is evolving from traditional to modern production practices. City’s leaders established numerous policies that emphasise green, circular economies, climate change resilience, and low carbon emissions fuelling demand for agricultural solutions that integrate traditional and modern technologies that can be embedded in the local topography, soil types, architectural space, and native culture. Findings from greenhouse trials, community awareness surveys, and stakeholder-led workshops point to a range of high-technology-supported agriculture models that, if applied flexibly throughout the varying context of the urban area, have good scope to help Ho Chi Minh City and meet its growing need for food as well as its sustainability aspirations.

Adequate, reliable, and efficient urban infrastructure systems (UIS) are fundamental to sustainable development, social mobility, and economic vitality. As communities continuously rely on basic infrastructure services to support their daily communal functions, major components of UIS are subject to heavy use, and thus rapidly deteriorate over time; hence, it is critical that efficient infrastructure management strategies practices are in place. As current strategies remain confronted with various limitations including adaptability to changing conditions, lack of public engagement, and cost-effectiveness, this study explores social media data mining as an approach to revitalise and support current urban infrastructure monitoring strategies by extracting valuable insights from public opinion. Twitter messages or ‘Tweets’ pertaining to public infrastructure in The Philippines were collected and analysed to identify recurring issues in public infrastructure, emerging topics in public discussions, and the overall perception of the public on infrastructure services. This study presents a topic model that extracts dominant topics from aggregated social media data and a sentiment analysis model that determines public opinion sentiment in relation to different urban infrastructure components. The findings of this study highlight the potential of social media data mining to surpass the limits of conventional data collection techniques and the importance of public opinion as a key driver for a more user-involved decision-making in infrastructure management and as an important social aspect that can be utilised to support planning and response strategies in routine maintenance, preservation, and improvement of UIS.

Through a case study of the Po Klaong Girai temple in Vietnam, this paper explores how indigenous community perceive tourism benefit sharing (TBS) associated with their cultural tourism at sacred living-heritage sites and how this TBS enhances the equality and inclusion for indigenous community in the context of tourism in Vietnam.

This study employed ethnographic fieldwork and semi-structured interviews with 35 indigenous Cham priests directly associated with managing and preserving the Po Klaong Girai temple.

This research found that Cham community perceive inequality and exclusivity on tourism benefit sharing at this religious site. While Cham Ahier priests face economic barriers in providing these services to the community, annual tourism revenue is allocated to local government budgets. Such economic pressure forces the priests to seek alternative economic avenues to support their families at the expense of their traditional commitments to communal, cultural and religious activities, significantly impacting sustainable heritage conservation. This has led to strained relations between the local community and local authorities.

This research provides evidence to improve living heritage management practices by proposing tourism development policies for equality and inclusion among stakeholders, especially minorities and disadvantaged groups. This can be an experiential and necessary lesson for “dealing” with sustainable heritage management in heritage living sites in other ethnic minority areas in Vietnam and globally.

The findings from this study address the knowledge gap on equitable revenue sharing in heritage tourism, where financial benefits from the commodification of minority cultures should be used to support local communities and the custodians of indigenous heritage.

This research investigates the market for Western clothing in Vietnam, one of the most under‐developed countries of South East Asia. The intention is to look at factors which will assist economic development in Vietnam because economic growth generally leads to greater GDP per capita and this in turn leads to greater spending per capita on clothing. The country is making use of direct foreign investment (DFI) from the ‘Asian Tigers’ to modernise its industry. The lighter manufacturing industries, which include apparel, are expected to benefit. The population of Vietnam welcome this investment and the employment it is creating, and as the labour force changes from agrarian to urban the GDP is expected to rise. This rudimentary clothing industry is being established in Vietnam mainly to supply the markets in Asia but there are indications that there is a growth of local demand for western clothing. In this research the access to retail western clothing in Vietnam is explored from both secondary and primary data sources, and, conclusions drawn incorporating the economic prospects for the future size of the market. The results of the research show that although the country is experiencing strong growth now and there is demand for western clothing the future market will be small.

In this chapter, the author relates the historical trajectory of the Vietnamese revolution and its relentless willingness to build socialism despite external aggressions, first colonialist (France), then fascist (Japan), and finally imperialist (United States). The author traces the analysis back to the August (1945) revolution and the founding of the Democratic Republic of Vietnam. The author continues with the 30 years of wars for national independency, then with the two very difficult decades after the wars. The author studies the so-called “Doi Moi” (renewal) period and the economic advances it allowed, then the political aspects of the Vietnamese socialist system, before exposing the questions of international relations.

This research aims to investigate the effect of personal values on customer satisfaction and whether positive experiences lead to positive word of mouth (WOM) about the luxury hotel service from the Confucian perspective.

This research developed a structural equation model for testing. Research data collected from Confucian participants who have used luxury hotel services in Vietnam, where Confucianism is the dominant cultural paradigm.

The results show that there is a positive relationship between Confucian customer personal values and satisfaction, as well as between customer satisfaction and positive WOM; personal values had no effect on positive WOM.

This research implies that the personal values of Confucian consumers constitute the lens through which they view the world, thus the service personal values reflect their priorities on luxury hotel service consumption. A key to success for luxury hotel service providers lies in providing services that enhance Confucian customer personal values, which allow service providers to intercommunicate with the Confucian consumers’ core.

This research is significant because there is little research on personal values from the cultural mechanism of Confucian culture. This research also comes up with a richer understanding of the relationship between customer personal values and behaviors within the luxury hotel segment.

This study aims to investigate the influence of corporate social responsibility (CSR) on corporate sustainable performance (CSP) of small- and medium-sized enterprises (SMEs) by looking into the significance of mediating factors, namely, brand image (BI) and brand loyalty (BL), within the context of an emerging economy.

The authors conduct an extensive literature study on the subjects of CSR, BI and BL to assess their influence on the sustainable performance of SMEs in an emerging market. The study adopts a quantitative methodology. A total of 438 answers were obtained from a sample size of 513. The data of the SMEs in Vietnam was analyzed using the smart partial least squares structural equation modeling software, specifically version 3.3.2.

The results of the authors demonstrate notable and favorable correlations between CSR and CSP, CSR and BI and CSR and BL. Importantly, the findings contribute to existing knowledge by looking into the mediating influence of BI and BL in the relationship between CSR and CSP.

According to the authors’ understanding, a number of research have investigated the correlation between CSR and CSP within the realm of SMEs. Nevertheless, there is a scarcity of scholarly research examining the mediating function of BI and BL in this association. The study’s findings have important implications for entrepreneurs and senior management in effectively guiding their enterprises and improving their business strategies with an emphasis on sustainability in emerging markets. The outcome of this study has the potential to significantly contribute to SMEs in Vietnam as well as other emerging countries.
