FACTORS INFLUENCING THE INTENTION TO USE MOBILE MONEY: A STUDY IN BUSINESSES IN HANOI, VIETNAM
Abstract
The government's and people's expectations for the successful implementation of this activity are significant, but the scientific basis for its implementation remains limited. This study, the first of its kind in Vietnam since the aforementioned decision, aims to clarify the factors influencing consumer usage of Mobile Money, focusing on businesses in Hanoi, Vietnam. Mobile Money, a form of mobile wallet not linked to bank accounts, represents a new transaction method in Vietnam, catering to consumers' reduced use of cash. This research examines the factors affecting the intention to use Mobile Money among employees of businesses in Hanoi. To achieve this goal, the author relies on the Theory of Reasoned Action (TRA), the Theory of Planned Behavior (TPB), the Technology Acceptance Model (TAM), and risk perception variables to design the research model. With a sample of 479 employees who intend to use Mobile Money, hypotheses are tested using a multivariate regression model through quantitative analysis with IBM SPSS Statistics 20.0. The research results identify five factors that positively influence the intention to use Mobile Money: Perceived Ease of Use, Trust, Security and Privacy, Social Influence, and COVID-19 Risk Perception. The factor of Perceived Usefulness does not have a significant impact in this case. Particularly, heightened risk perception regarding COVID-19 or social instability leads to an increased intention to use Mobile Money. This study provides guidance to Mobile Money service providers on how to enhance users' intention to use their services. Additionally, it underscores how factors related to diseases or societal instability can alter or even disrupt initial intention or behavior models
EGG QUALITY COMPARISON OF TWO VIETNAMESE CHICKEN BREEDS (RI AND MIA)
In the context of the valorization of poultry biodiversity, this work represents a step
toward a better knowledge of the production abilities of local chicken breeds in Vietnam.
Local chicken breeds are indeed particularly well suited for low-input rearing systems, as
widely practiced in rural households of Vietnam. The socio-economic importance of these
breeds might be underpinned by a market valorization through the mounting of differentiated
quality value chains. Such a strategy needs the production potential of these local breeds to be
assessed using parameters of egg quality and quantity. This study presents data about egg
quality traits in two chicken breeds, the Ri and the Mia. The former is the most widespread
breed in Vietnam, while the latter is known to be in danger of extinction. Nineteen
parameters of quality of ninety eggs of Ri chickens and sixty eggs of Mia chickens were
measured, each for both 40 and 60-weeks old hens to take hens ages into account.Mean egg
weight of Mia eggs (44.70g) was significantly (p<0.001) higher than that of Ri eggs (41.68g).
The yolk to albumen ratio was not significantly different (p>0.05) between the two breeds at
the age of 40 weeks (Ri: 0.55; Mia: 0.58). For 60-weeks old hens, the ratio became
significantly (p<0.05) higher in Mia eggs compared to Ri eggs (0.64 vs. 0.57). No significant
difference (p>0.05) was recorded between the two breeds for parameters used for egg
freshness assessment (Haugh’s units and pH of albumen and yolk) or eggshell resistance
(maximal breakage force). Despite the small sample available for the study (due to the low
availability of Mia hens and eggs), significant differences in egg quality traits were thus
observed between these two breeds.Peer reviewe
Incidence of dengue and chikungunya viruses in mosquitoes and human patients in border provinces of Vietnam
Background: Dengue virus remains a major threat in Vietnam, while chikungunya virus is expected to become one. Surveillance was conducted from 2012 to 2014 in Vietnam to assess the presence of dengue and chikungunya viruses in patients hospitalized with acute fever in five Vietnam provinces neighboring Lao PDR and Cambodia. Surveillance was extended to mosquitoes present in the vicinity of the patients' households. Results: A total 558 human serum samples were collected along with 1104 adult mosquitoes and 12,041 larvae from 2250 households. Dengue virus was found in 17 (3%) human serum samples and in 9 (0.8%) adult mosquitoes. Chikungunya virus was detected in 2 adult mosquitoes (0.18%) while no chikungunya virus was detected in humans. Differing densities of mosquito populations were found, with the highest in the Long An Province border with Cambodia. Long An Province also displayed the lowest rate of infection, despite a very high Breteau Index, high human population density and presence of the main cross border road system. The highest incidence was found in Dac Nong Province, where the Breteau and Container indices were the second lowest. Dengue virus was detected in five Aedes albopictus, three Aedes aegypti and one Culex vishnui. Chikungunya virus was detected in two Ae. aegypti. All infected mosquitoes belonged to haplotypes described in other parts of the world and a number of novel haplotypes were found among uninfected mosquitoes. Conclusions: Dengue is considered to be regularly introduced to Vietnam from Cambodia, mostly through human movement. The data reported here provides a complementary picture. Due to intensive international trade, long-distance transportation of mosquito populations may play a role in the regular importation of dengue in Vietnam through Ho Chi Minh City. It is important to decipher the movement of mosquitoes in Vietnam, not only at the Lao PDR and Cambodia borders but also through international trade routes. Mosquito surveillance programs should address and follow mosquito populations instead of mosquito species
Effects of water scarcity awareness and climate change belief on recycled water usage willingness: Evidence from New Mexico, United States
The global water crisis is being exacerbated by climate change, even in the United States. Recycled water is a feasible alternative to alleviate the water shortage, but it is constrained by humans’ perceptions. The current study examines how residents’ water scarcity awareness and climate change belief influence their willingness to use recycled water directly and indirectly. Bayesian Mindsponge Framework (BMF) analytics was employed on a dataset of 1831 residents in Albuquerque, New Mexico, an arid inland region in the US. We discovered that residents’ willingness to use direct recycled potable water is positively affected by their awareness of water scarcity, but the effect is conditional on their belief in the impacts of climate change on the water cycle. Meanwhile, the willingness to use indirect recycled potable water is influenced by water scarcity awareness, and the belief in climate change further enhances this effect. These findings implicate that fighting climate change denialism and informing the public of the water scarcity situation in the region can contribute to the effectiveness and sustainability of long-term water conservation and climate change alleviation efforts
Identifying Live Bird Markets with the Potential to Act as Reservoirs of Avian Influenza A (H5N1) Virus: A Survey in Northern Viet Nam and Cambodia
Wet markets are common in many parts of the world and may promote the emergence, spread and maintenance of livestock pathogens, including zoonoses. A survey was conducted in order to assess the potential of Vietnamese and Cambodian live bird markets (LBMs) to sustain circulation of highly pathogenic avian influenza virus subtype H5N1 (HPAIV H5N1). Thirty Vietnamese and 8 Cambodian LBMs were visited, and structured interviews were conducted with the market managers and 561 Vietnamese and 84 Cambodian traders. Multivariate and cluster analysis were used to construct a typology of traders based on their poultry management practices. As a result of those practices and large poultry surplus (unsold poultry reoffered for sale the following day), some poultry traders were shown to promote conditions favorable for perpetuating HPAIV H5N1 in LBMs. More than 80% of these traders operated in LBMs located in the most densely populated areas, Ha Noi and Phnom Penh. The profiles of sellers operating at a given LBM could be reliably predicted using basic information about the location and type of market. Consequently, LBMs with the largest combination of risk factors for becoming virus reservoirs could be easily identified, potentially allowing control strategies to be appropriately targeted. These findings are of particular relevance to resource-scarce settings with extensively developed LBM systems, commonly found in South-East Asia
Prospects for Food Fermentation in South-East Asia, Topics From the Tropical Fermentation and Biotechnology Network at the End of the AsiFood Erasmus+Project
Fermentation has been used for centuries to produce food in South-East Asia and some foods of this region are famous in the whole world. However, in the twenty first century, issues like food safety and quality must be addressed in a world changing from local business to globalization. In Western countries, the answer to these questions has been made through hygienisation, generalization of the use of starters, specialization of agriculture and use of long-distance transportation. This may have resulted in a loss in the taste and typicity of the products, in an extensive use of antibiotics and other chemicals and eventually, in a loss in the confidence of consumers to the products. The challenges awaiting fermentation in South-East Asia are thus to improve safety and quality in a sustainable system producing tasty and typical fermented products and valorising by-products. At the end of the “AsiFood Erasmus+ project” (www.asifood.org), the goal of this paper is to present and discuss these challenges as addressed by the Tropical Fermentation Network, a group of researchers from universities, research centers and companies in Asia and Europe. This paper presents current actions and prospects on hygienic, environmental, sensorial and nutritional qualities of traditional fermented food including screening of functional bacteria and starters, food safety strategies, research for new antimicrobial compounds, development of more sustainable fermentations and valorisation of by-products. A specificity of this network is also the multidisciplinary approach dealing with microbiology, food, chemical, sensorial, and genetic analyses, biotechnology, food supply chain, consumers and ethnology
Exploring Destination Loyalty: Application of Social Media Analytics in a Nature-based Tourism Setting
User-generated content across social media platforms is playing an increasingly important role in the tourism context. Understanding tourists’ experiences and opinions about tourism destinations has led to numerous opportunities to provide tourism providers and decision-makers with greater insight. Identifying sentiments, detecting topics of interest, and exploring loyalty behaviors from user-generated content can provide valuable direction for managerial decisions. Few if any studies on social media analytics have demonstrated the support for strategic decision-making. This paper presents a novel and inclusive approach that uses different analytical techniques such as sentiment analysis and topic modeling to extract sentiments and topics of interest from tourists’ conversational data on TripAdvisor from 2002 to 2019, and also explore destination loyalty statements using a keyword clustering approach. Previous destination loyalty literature was used to develop a keyword list that was applied to search for expression of loyalty in online reviews. The robustness of loyalty clusters and optimal number of clusters was also assessed prior to final analysis. Four leading loyalty-focused categories of destination offerings were observed: glaciers, waterfalls, lakes and islands, and hiking and trails. Prioritization of visitor experience enhancements relating to these loyalty inducing destination components are discussed
