THE INFLUENCE OF FOOD IMAGE ON TOURIST SATISFACTION AND WORD-OF-MOUTH INTENTION: THE CASE OF DALAT, LAM DONG PROVINCE, VIETNAM
Get PDFLocal food influences destination choice and enhances destination attractiveness. This study explores the links among food image, tourist satisfaction, and word-of-mouth (WOM) intention regarding local food in Dalat, Lam Dong Province, Vietnam. A quantitative method was applied to a sample of 327 domestic tourists chosen by convenience sampling. A model was proposed and then tested using confirmatory factor analysis and structural equation modeling. The results confirm the existence of significant relationships among food image, tourist satisfaction, and WOM intention. Tourist satisfaction is influenced by three significant dimensions of food image: food safety and health, restaurant service, and food taste and popularity. This study explores how restaurant service influences both tourist satisfaction and WOM intention. A negative relationship between food safety and health and WOM intention was found. Moreover, the results demonstrate that tourist satisfaction has a critical effect on WOM intention. The study also suggests some managerial implications for enhancing the use of local food and its image to encourage tourist satisfaction and WOM intention

QUANTUM TELEPORTATION OF ENTANGLED STATES VIA GENERALIZED PHOTON-ADDED PAIR COHERENT STATE
Get PDFIn this paper, we study the quantum teleportation of an unknown atomic state based on the two-photon Jaynes-Cummings model, consisting of an effective two-level atom with a two-mode field in the generalized photon-added pair coherent state (GPAPCS). By applying the detecting method, we use a scheme that includes two two-level atoms and a cavity field to teleport the unknown atomic state from a sender to a receiver. The results show that the number of photons added to the field and the intensity of the initial field influence the average fidelity and success probability of the teleportation process. The time-evolution dependence of the average fidelity is also considered and compared for the field in the pair coherent state and in the GPAPCS
INVESTIGATING THE EXPERIENCES OF STUDENTS WITH DISABILITIES WITH E-LEARNING DURING THE COVID-19 PANDEMIC IN VIETNAMESE HIGHER EDUCATION
Get PDFThis study uses a mixed-methods approach to investigate the experiences of Vietnamese university students with disabilities (visual/mobility impairments) with e-learning as a consequence of emergency remote teaching during the COVID-19 pandemic. An analysis of the ideas of 20 surveyed students with disabilities at eight universities in Ho Chi Minh City and six students interviewed afterward shows that students can change their study habits to adapt to e-learning and to enjoy this model of learning. However, the participants revealed that they also want to experience face-to-face learning so that they can interact with their lecturers and peers more effectively and in more diverse ways, as well as assimilate lectures more easily. Furthermore, the research shows that various adjustments should be made by system designers, universities, and lecturers to make e-learning friendlier to disabled students. The recommended adjustments include designing easy-to-use learning tools and platforms, providing lecturers with the necessary tools and facilities to design lessons appropriate for all students, providing psychological and technical support for disabled students, choosing user-friendly learning applications and platforms, providing students with suitable learning resources, and modifying testing and assessment methods
AN UPDATED CHECKLIST AND COMMENTS FOR SECTION PIQUETIA (CAMELLIA, THEACEAE)
Get PDFNew Camellia species in section Piquetia have recently been discovered. It is necessary to enumerate the number of species and update the specific characteristics of this section. Based on the study of more than 30 pieces of literature and a large number of specimens, a total of 15 species belonging to section Piquetia, including two new species, are identified. A taxonomic key to all species is provided, and typical characteristics of the section are also discussed. Information on the distribution, ecology, and conservation status of each species, as well as notes on the differences between closely related species, is also provided.
IMPACT OF EXTERNAL DEBT ON FINANCIAL DEVELOPMENT: AN EMPIRICAL ANALYSIS OF SELECTED EAST ASIAN AND PACIFIC COUNTRIES
Get PDFThis article explores the impact of external debt on financial development in a group of fifteen selected East Asian and Pacific countries from 1992 to 2021. These countries include Cambodia, China, Fiji, Indonesia, Lao PDR, Mongolia, Myanmar, Papua New Guinea, the Philippines, Samoa, the Solomon Islands, Thailand, Tonga, Vanuatu, and Vietnam. Data were extracted from the World Bank and International Monetary Fund databases. This study employs random effects and fixed effects models, Driscoll-Kraay standard errors, and the generalized method of moments to test two hypotheses. The results indicate that external debt has a positive impact on the financial development of these East Asian and Pacific countries, where economic growth plays a vital role in promoting financial development. Additionally, a nonlinear impact of external debt on the financial development of these East Asian and Pacific countries is observed. Based on these findings, it is recommended that appropriate financial development policies be implemented in the identified countries
THE TRIEU TUONG MAUSOLEUM SITE: RESULTS OF THE 2019 EXCAVATION
Get PDFTrieu Tuong Mausoleum is the place to worship the ancestors of the Nguyen royal family in their homeland. This is also where Nguyen Kim (Emperor Tinh) was buried. To conserve, embellish, and promote the historical and cultural heritage of the mausoleum, the Department of Culture, Sports and Tourism of Thanh Hoa Province coordinated with the Vietnam Institute of Archaeology to conduct a third excavation at the site in 2019. This article presents the research progress, essential documents related to the excavation at the mausoleum site in 2019, and an evaluation of the outstanding value of the relics and artifacts obtained from the mausoleum and contributes to the study and research into the history and culture of the Nguyen Dynasty in Vietnam
THE IMPACT OF DATA SECURITY ON THE INTENTION OF VIETNAMESE CONSUMERS TO USE E-WALLETS
Get PDFE-wallets are used as a form of payment that brings many benefits to users. This article studies the impact of data security on consumer intentions to use e-wallets in the rapidly growing economy of Vietnam. The data consist of 236 observations from a survey of consumers in Vietnam. Covariance-based structural equation modeling (CB-SEM) was employed to test the proposed hypotheses. Research results show that security trust has the greatest impact on the intention to use e-wallets, followed by perceived privacy risk, social influence, and information sensitivity. The study also reveals the role of privacy policies and security concerns in consumer intentions to use e-wallets. Based on the research results, the study provides recommendations for consumers, e-wallet providers, and governmental agencies to increase awareness of and responsibility for information security among the consumers who use e-wallets

VULNERABLITY OF RURAL LIVELIHOODS IN NINH THUAN PROVINCE TO DROUGHT
Get PDFThe risk of drought poses a significant challenge to agricultural production in Ninh Thuan Province. Therefore, this study aims to identify the factors that influence farmers’ livelihood outcomes due to the impact of drought. Data were collected from a survey of 231 farmers randomly selected from the districts of Thuan Nam, Thuan Bac, and Ninh Hai. In addition to descriptive statistics, a Tobit regression model was used to identify the factors influencing livelihood outcomes during mild and severe droughts. The results showed that farmers’ livelihood outcomes were generally low. The regression identified the financial (β=0.230 and 0.205), social (β=0.200 and 0.291), and human capital (β=0.195 and 0.196) impacts on farmers’ livelihood outcomes from both mild and severe droughts. During mild drought years, seasonal adjustment (β=-0.009) and migration (β=0.013) were found to significantly influence livelihood outcomes. In severe drought years, government support (β=-0.030) negatively affected livelihood outcomes. There is a need to establish an early warning system for climate change and extreme weather events while simultaneously disseminating information widely to farmers so that they can take timely measures to cope. Enhancing human capital by raising awareness and skills in adapting to drought and developing comprehensive abilities to implement drought adaptation strategies is needed
