Abstract

Purpose

This study aims to investigate the effect of spray drying temperature and maltodextrin addition on the contents of phenolics, flavonoids, anthocyanins and antioxidant activities (2,2-diphenyl-1-picrylhydrazyl [DPPH] radical scavenging activity, ferric reducing antioxidant power and reducing power) of karonda powder.

Design/methodology/approach

Over the past few decades, the demands for application of natural colorants in food production have been attracting the attention of academic research and food industry. Anthocyanins, a red pigment commonly found on plants, show high potentials in the preparation of spray-dried pigment powder. This study, therefore, was conducted using full factorial design with two factors, namely, inlet temperature (150°C and 160°C) and soluble solid concentration (10, 15 and 20°Brix) with maltodextrin as carrier to produce pigment powder from karonda, an anthocyanin-rich fruit which is native to southeast Asia.

Findings

Increasing soluble solid content from 10 to 15°Brix resulted in a 42%–57% reduction in phenolic, flavonoid and anthocyanin contents. However, when increasing the amount of maltodextrin from 15 to 20°Brix, a lower reduction (approximately 11%–19%) was observed. In samples with the same °Brix, there was no significant variation in antioxidant contents and activities, especially at high maltodextrin ratios. In addition, the reducing power of samples dried at higher temperature (160°C) was higher than that of samples dried at lower temperature. Karonda spray-dried powder showed a good positive correlation (p < 0.01) between antioxidant contents and DPPH• activity.

Originality/value

To the best of the authors’ knowledge, in this study, for the first time, the effect of spray drying conditions on the quality of karonda powder was investigated.

Abstract

Purpose

The purpose of the present research is to examine the comparative values that urban Vietnamese consumers place on attributes of rice that is produced using environmentally friendly methods. The authors consider the impacts that this may have on the livelihoods of rural Vietnamese small farmers. Rice is an “impure public good” that includes both “private” and “public” attributes that consumers consider in their purchase decisions. Consumers make tradeoffs between environmentally and socially beneficial practices (public goods) and perceptions of product quality (private goods). The authors used latent class modeling to investigate the values associated with attributes of rice that is produced using sustainable farming practices.

Design/methodology/approach

The authors used a discrete choice experimental design in which consumers stated their choices among combinations of rice attributes. The survey provided responses from 360 urban Vietnamese consumers and allowed to estimate the preferences and nonpecuniary values for rice grown using different levels of environmentally beneficial production methods.

Findings

The results identify two segments of rice consumers: one group of consumers who are sensitive to price and the other group who are sensitive to environmental issues. The individual characteristics are reflected in the choices of production methods and in the willingness to pay for environmentally beneficial outcomes of those methods.

Research limitations/implications

Given the number of independent variables measured, the sample was relatively small, such that confirmatory statistical methods were inconclusive. However, the authors used multiple analytical tools that provide corroboration of the significant determinants of the utility functions for the two segments.

Practical implications

The results provide directions for production of rice at a national level, as well as practical implications for consumer-oriented communications.

Social implications

Results suggest that the emerging middle class of Vietnamese consumers are willing to pay more for rice that is produced using methods that are beneficial to the environment. Results also indicate challenges to provide sustainably-produced rice to poorer groups of consumers.

Originality/value

The study provides important context for consumer preferences within emerging economies. This also adds to a growing literature that uses the choice experiment method to estimate consumer valuation of the outcomes of various agricultural practices.

Abstract

Purpose

This paper aims to investigate the sentiment connectedness among 10 European stock markets between January 2020 and July 2022, associating such connectedness with the level of the geopolitical risk index.

Design/methodology/approach

For this purpose, a time-varying parameter vector autoregressive connectedness framework is used.

Findings

Results show a high degree of sentiment connectedness. Overall, the sentiments of Portugal, France, the Netherlands, Spain, Germany and Italy are net transmitters of shocks while those of Poland, Sweden, Norway and Romania are net receivers. Additional evidence indicates that when geopolitical risks increase, the sentiment connectedness tends to decrease. However, the reverse holds under extremely high levels of geopolitical risks.

Originality/value

Overall, this study provides some significant contributions to the literature. First, to the best of the authors’ knowledge, this is among the first few studies to examine the dynamic connectedness among stock market sentiment across countries. This issue needs special consideration for European countries because of their close geographical distance and strong integration due to the European Union’s co-development strategies. Second, the association of sentiment connectedness with geopolitical risk is examined for the first time. This is even more meaningful in the context of growing geopolitical risks stemming from the Ukraine war, which could affect international financial markets.

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.

Abstract

In response to COVID-19 global outbreaks, Canada, and Australia, two favored destinations by international students, as the contexts of this essay, have enacted different international education policies, which will be investigated through the narratives. The authors discuss transnationality and mobility as key terms in the internationalization of higher education (HE) studies through their experiences as three Vietnamese doctoral students in Canada and Australia. Transnationality is attended through a narrative of a Vietnamese returnee struggling with bringing unfamiliar knowledge of gender and sex education from the West into a Vietnamese HE context. Mobility is unpacked through stories of a Vietnamese doctoral student in Canada stuck in Vietnam due to the COVID-19 despite inviting policies from the Canadian government to international students. This experience is connected to another Vietnamese student’s experience in Australia about a controversial act to discourage international students from staying in Australia if they cannot support themselves during the pandemic. The authors’ stories are created and retold personally for introspective and contemplative reflections on what the authors have experienced and offer considerations for how transnationality and mobility in international and comparative education could be understood through education, equity, and inclusion.

Abstract

This paper focuses on dry port as a key notion in port-hinterland development. We first discuss the concept of dry port by reviewing existing literature. Then, we explore the reasons behind the emergence and development of inland node systems in different geographical, economic and institutional contexts. Next, the paper presents a classification of dry ports based on a multitude of factors and dimensions and the respective benefits to different parties. The study then focuses on the specific characteristics of dry ports and associated transport networks in developing countries.

In the last part, we present a case study on the dry port system in Vietnam by reviewing the seaport and inland transport system and analyzing the current status of inland terminals in Vietnam. To conclude, a SWOT analysis is presented with regard to the development of the dry port network in Vietnam, followed by recommendations for policy makers.

Abstract

Purpose

Despite huge investments within the modern trade arena, Vietnam remains a traditional trade retailing country. The purpose of this paper is to establish the combined effects of motivation, store attributes and demographic factors on the predictive outcome of store format choice in Vietnam.

Design/methodology/approach

A logistic regression model is used to determine the effect of these factors on the predictive outcome of traditional markets or supermarkets in purchasing non-food products or processed food products.

Findings

The dichotomy between what supermarkets and traditional markets have to offer is simple but effective. Utilitarian-motivated shoppers are more likely to shop at traditional markets. They emphasize the need to buy products quickly, find a good price, with less travel time and hence lower travel costs. Hedonistic shoppers are motivated by feelings of happiness; they shop to relieve stress and to keep up with trends. Significant difference in store choice also exists between older and higher income shoppers.

Research limitations/implications

Future research should examine the sociocultural dimensions of shopping at traditional stores by exploring how such shopping relates to, and is embedded in, the formation and changes of individual identity, especially in communities outside of Ho Chi Minh City where shoppers are almost entirely dependent on traditional stores.

Practical implications

Traditional stores have the benefit of convenient location and savings in both time and travel costs. These benefits are being eroded as supermarkets and transnational retail corporations establish new stores close to the traditional stores.

Social implications

Shopping at traditional markets is part of the social culture and is embedded in individuals’ identity formation, despite increasing urbanization and shoppers’ higher incomes.

Originality/value

This study comprehensively explores the interactions between store choice and motivation, store attributes and demographic factors, taking into account contemporary and contextually relevant factors.

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

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

This study aims to identify the level of political participation of local citizen in 208 districts representing for 63 provinces and cities in Vietnam and consider the effects of candidate's attributes, local political contextual factors and other local citizen’s demographic characteristics on the elections of local leaders in Vietnam.

Design/methodology/approach

By using Probit model and data about provincial governance and public administration performance index and self-survey about local leaders in the districts, this paper shows the different effects of candidates’ attributes, local political context and other local citizen’s characteristics on the first and second elections of local leaders in Vietnam.

Findings

The result indicates the probability of candidates being elected in the first term depends on their characteristics, local political context and local citizen. However, the reelection of local leaders for a second term depends much on their characteristics and local political context not on demographic characteristics of local citizen. The satisfaction rate of local citizen and being an incumbent for the first term are driving forces for the local citizen to elect their leader for the second term. Meanwhile, local political context such as local transparency, local official development assistance project and citizen satisfaction will increase the likelihood of local leaders being elected for the first and second terms.

Research limitations/implications

The major limitation of this study is the data of the self-survey because it only provides basic but not complete characteristics of candidates and local contexts in some typical districts in 63 provinces and cities across the country.

Practical implications

This paper includes policy implications for candidates who want to be elected for both terms and local governance in Vietnam. The government needs to focus on building human resources for local administration to meet the requirements of building a clean, strong, modern and anticorruption administrative system.

Originality/value

This paper extends the analysis on examining the characteristics of candidates and local citizen as well as local political context influencing the elections of local leaders, getting involved in the Vietnam context, still underresearched, especially with reference to political participation of local citizen.
