Guided by a resource-based theory, this study is the first one that takes a quantitative approach to identify determinants of competitiveness of women-owned small and medium enterprises (SMEs) in Vietnam. The study employs time series data of Vietnamese SMEs extracted from the Vietnam Small and Medium Enterprises Survey conducted biennially from 2005 to 2015 in ten Vietnamese provinces. Firm competitiveness hereby is indicated by revenue, market share, profitability, and export volume. The research reveals a number of determining factors, of all, research and development, labor skills, business environment, technology investment are the most important factors, followed by capital and headcount. It is indicated that the determining factors have different influences on competitiveness obtained by different measurements. Therefore, it is based on specific targets and situations to make wise business decisions. The authors also make comparisons among groups of women-owned enterprises divided by their firm age, location, ownership, export, age, and educational background of business owners. The findings serve as critical empirical evidence and provide policy recommendations for improving the competitiveness of women-owned SMEs in Vietnam. The recommendations range from technology support, education and professional support for female entrepreneurs, access to capital and human resources to business environment improvement.

Impacts of Foreign Direct Investment on Human Capital in ASEAN
Hoi Van NGUYEN,Thuy Thi Thu NGUYEN,Tha Hien TO,Duong Quy DANG,Trang Thi Dai Luong 한국유통과학회 2020 유통과학연구 Vol.18 No.9
Purpose: Research and development of human capital in countries bring sustainable development to the nations. Especially for developing countries, the attraction of foreign direct investment not only brings economic growth to the country but also contributes to improving human capital. This study aims to assess the impact of foreign direct investment on human capital in ASEAN countries. Research design, data and methodology: With data collected from ASEAN countries from 1990 to 2019, panel data analysis is performed with revised model types (the Pooled OLS, Fixed effect model, Random effect model and regression with Driscoll-Kraay standard errors). Result: The results of the regression analysis show that FDI has a positive impact on human capital. At the same time, the study also found that public investment in education also positively affects human capital; the life expectancy factor does not affect human capital. Conclusions: With this research result, the authors also proposed a number of solutions to improve human capital by attracting FDI and improving the efficiency of investment for the education of ASEAN countries. Besides, public expenditure on education also plays an important role in raising human capital. Therefore, investment in education should be promoted further in the future.

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.

<P>This study investigated the profiling of polycyclic aromatic hydrocarbon- (PAH-) induced genotoxicity in cell lines and zebrafish. Each type of cells displayed different proportionality of apoptosis. Mitochondrial DNA (mtDNA) copy number was dramatically elevated after 5-day treatment of fluoranthene and pyrene. The notable deregulated proteins for PAHs exposure were displayed as follows: lamin-A/C isoform 3 and annexin A1 for benzopyrene; lamin-A/C isoform 3 and DNA topoisomerase 2-alpha for pentacene; poly[ADP-ribose] polymerase 1 (PARP-1) for fluoranthene; and talin-1 and DNA topoisomerase 2-alpha for pyrene. Among them, lamin-A/C isoform 3 and PARP-1 were further confirmed using mRNA and protein expression study. Obvious morphological abnormalities including curved backbone and cardiomegaly in zebrafish were observed in the 54 hpf with more than 400 nM of benzopyrene. In conclusion, the change of mitochondrial genome (increased mtDNA copy number) was closely associated with PAH exposure in cell lines and mesenchymal stem cells. Lamin-A/C isoform 3, talin-1, and annexin A1 were identified as universal biomarkers for PAHs exposure. Zebrafish, specifically at embryo stage, showed suitable <I>in vivo</I> model for monitoring PAHs exposure to hematopoietic tissue and other organs.</P>
