The Demand of Urban Consumers for Safe Pork in the Vietnamese Mekong Delta

This study applied the contingent valuation method to analyze the consumers’ demand for the proposed safe pork. The data was collected by face-to-face interviewing 884 urban households in the Vietnamese Mekong Delta. The results revealed that the majority of consumers (about 64%) paid attention to the proposed safe pork. Their willingness to pay was about VND 176,000 ($ 7.65) per kg, nearly double compared to the market price of conventional pork. The results showed that the respondents who had higher household income, larger proportion of elderly and children in the family, paid higher price of a conventional pork, and get more knowledge score on the safe pork are more likely, while the respondents who have more number of family members are less likely to pay for the proposed safe pork

Research on Criteria for Operational Audit of Expenditure from State Budget in Vietnam

In Vietnam, operational audits have been upgraded as an independent form of audit in the operation of the supreme audit agency. However, because it was introduced later than other types of audit, it is still confusing and general in setting criteria of audit. There are no specific guidelines for auditing expenditure from state budget. Therefore, the formation and application of audit criteria in the audit practice of expenditure from state budget has not been effective, spontaneous and influenced by the actual capacity of assigned auditors. Meanwhile, in order to perform the proper audit function, the most important thing is to build up the evaluation criteria. Based on data collected both secondary and primary from interviewing auditors, experts in the field of state budget, we conducted the synthesis, analysis, evaluation, comparison and clarification of research issues. The results show that the formation of audit criteria is not really reasonable; criteria for economic efficiency and effectiveness are sometimes unclear. Therefore, this study is to identify and develop criteria for evaluating the operational audit of expenditure from state budget in Vietnam.

Isolation and characterization of Rhizobium spp. and Bradyrhizobium spp. from legume nodules

Rhizobia topic has been re-focused in recent years because of new findings on their traits not only as nitrogen-fixing bacteria but also as plant growth-promoting rhizobacteria. When combing rhizobial strains with novel biological carriers (e.g., biochar) for inoculant production, it brings great potential for improving soil health in long-term. Appreciating this trend, this study is designed to isolate and characterize local rhizobial strains from legume fields using the conventional method with some modifications to increase efficiency in rhizobial identification. As a result, 17 rhizobial strains were isolated and classified biochemically that genetic identification outcome confirmed 10 strains belong to 07 different Rhizobium species as R. mayense, R. paknamense, R. pusense, R. miluonense, R. tropici, R. phaseoli, and R. multihospitium while the rest belong to 06 various Bradyrhizobium species as B. elkanii, B. centrosematis, B. guangxiense, B. liaoningense, B. yuanmingense, and B. arachidis. Thermal and saline tolerant tests together with seed germination tests also performed on these rhizobial strains to gain data on their responses to abiotic stresses. By comparing rice and mung bean GI values, we can assess the effectiveness of each rhizobial strains to help seeds at their early germination

Choice modeling approach to evaluate the economic value of renewable energy development

Purpose. This research aims to quantify the willingness to pay (WTP) of urban residents in the Mekong Delta for the environmental and social benefits associated with renewable energy projects. By analysing their preferences and priorities regarding renewable energy implementation, this study aims to contribute to the increasing knowledge on the drivers of sustainable energy transitions in developing regions. Methodology / approach. This paper leverages a choice modeling (CM) framework to analyse the economic viability of renewable energy investments in Vietnam. The CM technique is advantageous for its ability to capture individual preferences for complex goods or services characterised by multiple attributes and trade-offs. This enables a detailed assessment of the diverse economic values associated with renewable energy sources, beyond their traditional energy generation capacity, including environmental externalities, social impacts, and potential synergies with other sectors. Results. Residents showed significant WTP for renewable energy initiatives improving landscape aesthetics, wildlife habitats, air quality, and job opportunities. Higher income, education, and knowledge level are positively associated with greater WTP. Younger respondents showed a strong position in favor of renewable energy sources. Households with more children were less likely to support the status quo, and married respondents were more pro-renewable. Perceived community involvement emerged as a significant factor in supporting renewable energy policies. Originality / scientific novelty. This study represents a novel application of CM within the Vietnamese context, providing valuable quantitative data for policymakers and stakeholders. By estimating WTP for specific renewable energy attributes, we inform cost-benefit assessments and support the development of efficient policies for managing renewable energy investments. This data facilitates resource allocation and prioritisation of projects with the highest societal value. Practical value / implications. Our findings underscore the crucial role of public awareness and education in driving renewable energy implementation. Residents with a clear understanding of the benefits demonstrate a higher WTP. Hence, we recommend a multifaceted communication strategy to educate the public about the environmental, social, and economic benefits of renewable energy. This involves utilising diverse channels like community meetings, media outreach, online platforms, and expert engagement to disseminate accurate and engaging information. By fostering knowledge and understanding, we can cultivate a strong public mandate for renewable energy investment, facilitating informed decision-making and accelerating the transition to a sustainable energy future in the Mekong Delta

Current situation of Bitcoin management and use: perspectives from the world and recommendations for Vietnam

The research aimed to evaluate suitability of Bitcoin and its platform in emerging markets such as Vietnam. We used qualitative analysis combined with data collection method published, statistics, analysis, synthesis, comparison, to generate qualitative comments and discussion; evaluate results, the article analyzed and evaluated the impacts of Bitcoin and virtual currency on society of Vietnam, both positive and negative sides. It was found that virtual currency not accepted in Vietnam as means of payment yet, while many nations in the world accept it. We need to complete the legal framework for virtual currencies in general, Bitcoin in particular. The State should continue to have policies to improve information technology infrastructure, build and improve the capacity of the contingent of financial experts, encryption, and security experts and give warning risks in virtual currency transactions. The scientific value of paper is using experiences from previous studies in other countries to generate recommendations for conditions of Bitcoin development in merging markets. Last but not least, the research was limited to the case of Vietnam; hence, we can expand research to other Asian countries or other emerging markets
