A Partial Least Squares Path Model of Repurchase Intention in Smartphone-based Ride Hailing Service
Nguyen,Ngoc Duy Phuong,Tran,Thi Dai Trang 한국유통과학회 2019 KODISA ICBE (International Conference on Business Vol.2019 No.-
The aims of this study are applying the Perceived value model and employing the three factors defining service quality of information system from DeLone and McLean’s success model to identify the key factors affecting repurchase intention in smartphone-based ride hailing service. The research framework was examined with 427 valid respondents from Grab and Uber customers in Vietnam. Partial Least Square (PLS) employed to analyze the measurement and structural model. The statistical results support all seven proposed hypotheses. The study confirm that service quality and electronic service quality of information system are significant predictors of overall perceived service quality. In addition, when customer perceives the service quality outweighs their sacrifices, the perceived value increase, subsequently results in higher repurchase intention towards smartphone-based ride-hailing service. Overall, other variables account for 51.1% of variance of repurchase intention. The study confirms the relationships of the three variables represent the electronic service quality and service quality with the overall service quality, which directly effects to perceived value, considering a more comprehensive model for service in m-commerce context.

This study seeks to examine the relationship between business resources (through VRIN: Valuable - valuable, Rare - scarce; Inimitable - difficult to adapt, Irreplaceable - hard to replace), dynamic capability, external cooperation, and efficiency of startups operating in the seafood export sector. Research data was collected randomly and conveniently from 250 enterprises in Ba Ria-Vung Tau province, Vietnam, from October 2020 to December 2020. After excluding those ineligible, the remaining 204 enterprises meet the research conditions. With the support of SPSS-AMOS 22 dedicated software, using the 5-step Likert scale and Structural Equation Modeling (SEM), the study conducted analysis steps such as verifying convergence, discriminant value, unidirectional and scale reliability when giving the components correlated freely in the critical model by Confirmatory Factor Analysis (CFA) analysis. Results of the study have shown that the enterprise resource factor - VRIN has a positive impact on dynamic capability, and outside cooperation. However, in contrast to previous studies, we found that the relationship between enterprise resources - VRIN and performance as well as the relationship between dynamics capacity and performance is not clear. This shows that seafood exporters need to promote, exploit and effectively use this precious resource to improve business efficiency.

This research aims to give information about the current situation of five financial sources for climate change in Vietnam, including (i) the State budget used by ministries; (ii) the State budget used by provinces; (iii) Bilateral funds; (iv) Multilateral funds; and (v) Private funds, and then classify them in line with the effectiveness. The working paper’s secondary data on spending on CC-related activities, collected from reports of six ministries and 29 provinces, show that the State budget has been crucial in subsidizing CC-related activities in Vietnam. Moreover, domestic investment has accounted for a major part of the total expenditure of ministries and provinces for climate change. In addition, by using primary data collected from surveys sent to twelve experts from 5 groups, such as researchers, practical experts, managers of private funding organizations (such as banks and enterprises), managers of international funding organizations and beneficiaries, and then analyzing the data through the AHP method, the study shows that all climate finance sources in Vietnam are still not very effective. However, private sector funds are considered the most effective financial source for responding to climate change.

Purpose: The paper employs the theory of planned behaviour, social identity theory, social presence theory, and social exchange theory to propose a model for using the social media platform Facebook in distributing information in universities. Research design, data and methodology: Data were obtained from 618 students at Hanoi University of Industry (HaUI) in Vietnam. The study used structural equation modeling in SPSS and the statistical analysis software AMOS version 24 to explore the information distribution role of Facebook. Results: Findings reveal that subjective norms and social presence play a key role in driving students to use Facebook for studying. In addition, university administrators can boost student satisfaction and academic achievement through Facebook. Interestingly, students who strongly identify with the brand name of the university have a strong connection with the university are more likely to engage in behaviors supportive toward the university. Conclusions: These findings show that Facebook had played a key information distribution role in universities. Thus, the study provides the executive board of the university and teachers can gain new understanding of why students employ Facebook for studying as well as capitalize on the platform to improve several operational metrics such as brand identification, student satisfaction, and academic achievement.

Purpose: This article focuses on exploring the associations between job satisfaction, organizational commitment, and turnover intention. Specifically, this study estimates the impacts of Vietnamese employees’ job satisfaction on their organizational commitment and turnover intention in FDI enterprises. Research design, data and methodology: The measures are adapted from previous studies to develop a questionnaire with a seven-point Likert scale. The dataset is directly collected from 227 respondents who are employees at FDI enterprises situated in the North of Vietnam. The dataset is analyzed by quantitative approaches using SPSS 24.0 and AMOS 24.0. Results: The results show that while turnover intention is positively correlated with monthly income, it is negatively correlated with job satisfaction and organizational commitment. Also, organizational commitment is positively associated with job satisfaction among employees at FDI enterprises in Vietnam. Conclusions: The findings of this study will serve as useful references for administrators of FDI enterprises and policymakers to promote employees’ job satisfaction and retain skilled employees.

This study performed phytochemical and bioactiveassessments of the mangrove Lumnitzera racemosaWilld. leaves. Bioassay-guided fractionation of the methanolicextracts led to the identification of thirty-six compounds(1–36), their structures were elucidated using detailed NMRspectroscopic and MS analysis. The extracts, fractions, andthe isolated compounds were screened for potential antioxidantand cytotoxic activities. Antioxidant assays wereperformed using peroxyl radical-scavenging and reducingassays, whereas cytotoxicity was measured using MTTassays in HL-60 and Hel-299 cell lines. The methanolicextract, CH2Cl2 and n-BuOH fractions (10.0 lg/mL)exhibited potent antioxidant activity, with Trolox equivalent(TE) values of 24.94 ± 0.59, 28.34 ± 0.20, and27.09 ± 0.37 (lM), respectively. In addition, the isolatedcompounds exerted cytotoxic effects in a dose-dependentmanner; compounds 1 and 14 exhibited the most potentcytotoxicity in HL-60 cells, with IC50 values of 0.15 ± 0.29and 0.60 ± 0.16 lM, respectively. To clarify the mechanism(s) behind these cytotoxic effects, we measured thetime-dependent changes in apoptotic markers including thecondensation and fragmentation of nuclear chromatin, andthe downregulation of p-ERK1/2, p-AKT, and c-Myc levels.

Objective: Fibronectin 3 (FN3) and immunoglobulin like modules (Ig) are usually collocated beside modular cellulase catalytic domains. However, very few researches have investigated the role of these modules. In a previous study, we have sequenced and analyzed bacterial metagenomic DNA in Vietnamese goats' rumen and found that cellulase-producing bacteria and cellulase families were dominant. In this study, the properties of modular cellulases and the role of a FN3 in unique endoglucanase belonging to glycosyl hydorlase (GH) family 5 were determined. Methods: Based on Pfam analysis, the cellulases sequences containing FN3, Ig modules were extracted from 297 complete open reading frames (ORFs). The alkaline, thermostability, tertiary structure of deduced enzymes were predicted by AcalPred, TBI software, Phyre2 and Swiss models. Then, whole and truncated forms of a selected gene were expressed in Escherichia coli and purified by His-tag affinity column for assessment of FN3 ability to enhance enzyme activity, solubility and conformation. Results: From 297 complete ORFs coding for cellulases, 148 sequences containing FN3, Ig were identified. Mostly FN3 appeared in 90.9% beta-glucosidases belonging to glycosyl hydrolase family 3 (GH3) and situated downstream of catalytic domains. The Ig was found upstream of 100% endoglucanase GH9. Rarely FN3 was seen to be situated downstream of X domain and upstream of catalytic domain endoglucanase GH5. Whole enzyme (called XFN3GH5 based on modular structure) and truncate forms FN3, XFN3, FN3GH5, GH5 were cloned in pET22b (+) and pET22SUMO to be expressed in single and fusion forms with a small ubiquitin-related modifier partner (S). The FN3, SFN3 increased GH5 solubility in FN3GH5, SFN3GH5. The SFN3 partly served for GH5 conformation in SFN3GH5, increased modules interaction and enzyme-soluble substrate affinity to enhance SXFN3GH5, SFN3GH5 activities in mixtures. Both SFN3 and SXFN3 did not anchor enzyme on filter paper but exfoliate and separate cellulose chains on filter paper for enzyme hydrolysis. Conclusion: Based on these findings, the presence of FN3 module in certain cellulases was confirmed and it assisted for enzyme conformation and activity in both soluble and insoluble substrate.

Nguyen Thi Phuong Mai. 2009. ‘A study on teaching Korean language-culture through television drama for Vietnamese learners’. Journal of the International Network for Korean Language and Culture. Vol. 6-1. 191-211. Korean dramas started the Korean wave in Vietnam and are still a favourite for Vietnamese people. Loving Korean dramas has become a motive for studying Korean language and culture among a great number of Vietnamese students. Therefore, using the Korean dramas as teaching materials would lure the attention from the students as well as create an interesting studying atmosphere. In addition, Korean dramas use lively and daily communication language so as to help students to approach to the modern language not the formal one stated in the textbooks. The study aims at recommending a suitable teaching methodology of Korean language and culture through television dramas. The contents of Korean language-culture teaching and learning methodology in this paper include three parts: linguistic etiquette, productive skill based on comparison of language and cultural characteristics of Vietnamese and Korean languages, and the general Korean language-culture teaching. Regarding the teaching methodology of Korean language and culture through television dramas, this study brings about some suggestions such as using drama as a audio visual media in practising speaking and listening skills, using drama script in improving the reading skill, and sharpening the writing skill by rewriting the script in the cross-culture perspective.(Vietnam National University-Hochiminh City)

Peroxisome proliferator-activated receptors(PPARs) are ligand-activated transcription factors thatregulate the expression of multiple genes involved inmetabolic, anti-inflammatory, and developmental processes. This study evaluated the PPARs transactivationaleffects of thirteen cembranoid diterpenoids 1–13 from thesoft coral Lobophytum crassum, using PPAR-responsiveelements–luciferase reporter and GAL4–PPAR chimeraassays. All isolated compounds activated the transcriptionof PPARs in a dose-dependent manner, with EC50 valuesranging from 2.07 ± 1.73 to 130.20 ± 1.85 lM. Moreover,compounds 6–9 affected the transactivation of allthree PPAR types, PPARa, c, b(d), in a dose-dependentmanner, with EC50 values in a ranging from 11.92 ± 1.23to 122.50 ± 2.12 lM. These results provide a scientificrationale for further studies on the soft coral L. crassum andits diterpenoid constituents to develop medicinal productsagainst inflammatory and metabolic diseases.
