Abstract

Purpose

The purpose of this paper is to analyze the results of recording electrophysiological signals by nanosensors during tests on volunteers using neutral questions and questions that cause excitement.

Design/methodology/approach

The nanosensor-based hardware and software complex (HSC) was used for simultaneous recording of electrocardiogram, electroencephalogram and galvanic skin response during tests on volunteers using neutral questions and questions that cause excitement. The recording was carried out in real time without averaging and filtering in the extended frequency range from 0 to 10,000 Hz, level of more than 1 µV and sampling frequency equal to 64 kHz.

Findings

For the first time, the following signals were recorded by nanosensors without filtering and averaging in the measuring channels: real-time micropotentials on an electrocardiogram with a duration of 0.2 ms and a level of 1 µV or more. Also, for the first time, changes in the shape and amplitude of the P wave, slow waves on the electroencephalography (EEG), high impulse activity of the EEG and impulse activity of short duration on the GSR were recorded in response to questions that cause excitement.

Practical implications

The obtained results will be used for high-resolution equipment to develop additional measuring channels in existing types of equipment for psychophysiological studies.

Originality/value

For the first time, new data undistorted by filters was obtained on the amplitude and time parameters of electrophysiological signals in the frequency range from 0 to 10,000 Hz in response to questions that cause excitement, which was due to high sensitivity and noise immunity of nanosensors in comparison with existing electrodes for biopotential recording.

Abstract

Purpose

The purpose of this paper is to show the adaptation of participatory concept: “from passive to active community” which is the key point to achieve successes of the case study project – a cultural village in Tam Thanh, Tam Ky, Quang Nam, Vietnam. Its achievements result from the employment of three principal steps including identifying core issues in the community, creating changes in human perceptions and living conditions, and demanding operation and maintenance of the community further. The project can seem to be an outstanding showcase for the applicability and possibility of other community projects around Vietnam.

Design/methodology/approach

The paper uses the previous community projects developed in Vietnam. However, they are less effective for the community in long-term due to ignoring/underestimating the role of local people. The case study is an impoverished residential neighbourhood in Tam Thanh, Quang Nam. The authors along with the colleagues observed and conducted the workshops on site to understand the problems, values and expectations of people and the land. The paper likes as a summary for achievements and lessons extracted from that field study. The comparison to the previous projects shows the efficiency of participatory design with the active involvement of the local community.

Findings

The practical experiences to find successes for the community projects in Vietnam: collaboration of experts, architects, volunteers and local people; classification of roles for groups of participants; the involvement of the local government. engagement of a collaborative relationship with the community under the patience, comprehension and sympathy of all members of the community; and role of the architects involving the projects should be supported for people’s participation to come up with the idea instead of proposing strict ideas.

Practical implications

The appropriate approaches on the right subjects and right time are the key of successes and sufficiency for the community projects, particularly to the impoverished neighbourhoods or places with sensitive issues. The Tam Thanh village is a typical example and its experiences can be disseminated for the other projects. It indicates the active and respectful involvement of like-minded people (experts, volunteers, sponsors, managers and in particular local people) is very important to achieve the final expected destination in the purpose for/by/with the community.

Social implications

The huge effect of community projects is directly on the local people. The approaching and understanding them is challenging. An achievable community project is that the real needs of the people are provided; they are aware of their roles and benefits; and finally, the values are retained and developed sustainably in long term. The community projects are characterised by the participation of many people in many different stages: analysis, design and implementation. Therefore, for the experts, volunteers and managers, they learn to listen to the voice of the local people and to avoid the forced thoughts and underestimation of local people’s involvement.

Originality/value

The value of the study is that the nature of participatory design method is shown through activities and results of the community project in Tam Thanh. The delivery from theoretical features to practical works is not easy and needs observation and understanding of local culture and life. Depending on each specific location, the application of this design theory is flexible and adaptive. An idea for every project is initiation; however, the participation of local people is key to the project’s achievement.

Abstract

Purpose

Previous research has yielded mixed results on the relationship between consumer perception and purchase intention towards organic food products. Although the prior literature has widely applied planned behaviour theory, using a single theoretical approach often provides limited understanding of organic food consumption. This study builds upon consumer perception and social cognitive theories to examine the effects of perceived food healthiness and environmental consciousness on the purchase intention of organic drinking products. The current research also assesses the mediating role of consumer extrinsic motivation and moderating role of corporate social responsibility (CSR) beliefs in these effects.

Design/methodology/approach

A survey method was applied to collect data from 606 consumers from different food retailers in Vietnam. Data were analysed using multivariate analysis techniques, such as structural equation modelling and bootstrap analysis.

Findings

Results of hypothesis testing support the predictive ability of perception and social cognitive theories in explaining consumers' perceptions, motivation and behavioural intention towards organic drinking products. Furthermore, results provide evidence for the moderating effect of CSR beliefs on the relationship between consumer extrinsic motivation and purchase intention.

Originality/value

This study may be amongst the first that explains consumption of organic drinking products from the perspectives of consumer perception and social cognitive theories. It provides a unique research model that explains the influence of perceived food healthiness and environmental consciousness on purchase intention of organic drinking products with the mediating role of consumer extrinsic motivation and moderating role of CSR beliefs. The current research provides fresh insights into the consumption of organic drinking products in an emerging market based on a mediated moderation mechanism, which has been limited in the prior literature.

Abstract

Purpose

In many countries, innovation in building design for improving energy performance, reducing CO2 emissions and minimizing life cycle cost has received much attention for sustainable development. This paper investigates the importance of optimization tools for enhancing the design performance in the early stages of Vietnam's cooling-dominated buildings in hot and humid climates using an integrated building design approach.

Design/methodology/approach

The methodology of this study exploits the non-dominated sorting genetic algorithm (NSGA-II) optimization algorithm coupled with building simulation to research a trade-off between the optimization of investment cost and energy consumption. Our approach focuses on the whole optimization problem of thermal envelope, glazing and energy systems from preliminary design phases. The methodology is then tested for a case study of a non-residential building located in Hanoi.

Findings

The results show a considerable improvement in design performance by our method compared to current building design. The optimal solutions present the trade-off between energy consumption and capital cost in the form of a Pareto front. This helps architects, engineers and investors make important decisions in the early design stages with a large view of impacts of all factors on energy performance and cost.

Originality/value

This is one of the original research to study integrated building design applying the simulation-based genetic optimization algorithm for cooling-dominated buildings in Vietnam. The case study in this article is for a non-residential building in the north of Vietnam but the methodology can also be applied to residential buildings and other regions.

Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Practical implications

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.

Originality/value

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.

Abstract

Purpose

This study aims to investigate the effect of the presence of women in top executive positions on financial reporting quality (FRQ) and the role of external audit in enhancing the role of women in top executive positions.

Design/methodology/approach

This study uses a sample of 644 Vietnamese-listed firms from 2010 to 2020 and applies fixed-effect and dynamic system generalized method of moments techniques for empirical models to test the related hypotheses.

Findings

First, this study found a U-shaped relationship between women on the board and FRQ as well as women on the audit committee and FRQ. Second, female CEOs are positively associated with FRQ in small firms but there is no evidence of this in large firms. Third, a female chief accountant can enhance FRQ. Finally, external audit quality can reduce the negative effect of women on the board and the audit committee on FRQ and increase the positive impact of female chief accountants on FRQ.

Practical implications

The results support all risk-averse, ethical sensitivity and glass ceiling hypotheses in different contexts. This study provides important implications for firms to enhance FRQ by nominating women in a majority of top executive positions and simultaneously using high-quality external audit services.

Originality/value

The impact of women in top executive positions on controlling FRQ in different contexts is an original contribution to gender in management literature.

Abstract

Purpose

The purpose of this paper is to investigate the relationship between the attitudes, skills and knowledge-based researchers’ competencies (ASK-RC), academic affiliation (AA) and knowledge management (KM) and its effect on promoting the growth of scholarly international publications (SIPs).

Design/methodology/approach

This research takes a quantitative approach relying on primary data gathered through a questionnaire-based survey. The study’s target population includes lecturers, managers and researchers involved in research activities in educational institutions. To operationalize the research framework, this study used social cognitive theory (SCT) and the academic community served as an empirical field of study.

Findings

The primary findings of this research are twofold: ASK-RC and AA are positively and statistically significantly associated with SIP; KM moderates the influence of ASK-RC on SIP.

Originality/value

This research adds to the current body of literature on research productivity by providing new information and empirical evidence on improving research productivity and international publication. Moreover, this research offers a new approach to the existing literature stream by operationalizing an underexplored framework from the lens of SCT. This study explains why scientific research productivity is becoming increasingly important to academia and stakeholders. Because scientific works are motivated by the goal of addressing general socioeconomic and environmental concerns, it is possible to address this concern based on SCT. Therefore, this research offers theoretical and managerial implications that may interest academics, professionals and policymakers.

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

Purpose

The main purpose of this paper is to analyze the sustainable inward FDI pattern of Vietnam.

Design/methodology/approach

This paper intends to analyze the sustainable FDI pattern of Vietnam using the gravity theory and panel data approach for the annual data over the period of 2007–2020.

Findings

Vietnamese FDI volume is positively affected by political and social factors, globalization and green energy consumption, while geographical distance is a major obstacle to the increase of FDI inflows of the country.

Practical implications

As the main practical policy implications, issuing policies for sustainable economic growth, launching the novel strategy of green FDI neighborhood policy and regionalism through free trade agreements are recommended.

Originality/value

To the best of author's knowledge, there has not been any in-depth academic study focusing on the Vietnam's sustainable FDI. In addition, three robustness checks have been conducted to ensure the validation of empirical findings.
