  • Spiradiclis hainanensis H.S. Lo and S. purpureocaerulea H.S. Lo (Rubiaceae) are reported as new additions to the flora of Vietnam. In Vietnam, the genus Spiradiclis has been represented by only two species, S. leptobotrya (Drake) Pit. and S. caespitosa Blume. During our field investigations in the Lao Cai and Ninh Binh Provinces of northern Vietnam, we collected two interesting specimens of Spiradiclis that were earlier known only from China and unknown in Vietnam. Here, we report S. hainanensis and S. purpureocaerulea as previously unrecorded species from Vietnam. Detailed descriptions and color photographs are provided along with a taxonomic key for Spiradiclis species in Vietnam.

  • Many publications of ecocritical research papers and translations of ecocriticism occur in Vietnam in recent years. This paper examines ecocritical scholarly writing in Vietnam, understanding how it corresponds to-reflects and attends to-contemporary Vietnamese society and politics. Specifically, this paper contextualizes Vietnamese ecocriticism in contemporary social and political concerns-embodied in journalistic and administrative documents-about the modernity-oriented postcolonial nation-building of Vietnam. In revealing critiques of political and social degenerations implied in ecocritical writings in Vietnam, this paper suggests that the emergence of ecocriticism in present-day Vietnam indicates a recent "political turn." More importantly, such emergence reflects and engages with the continuing Marxist perspective of literature as an instrument for social criticism and cultural revolution in Vietnam. Vietnamese ecocritics bear the mission of prophets of the time, public educators, and soul engineers, writing is an act of engaging with and influencing reality. Writing (literary and scholarly) still forms an idealized ideological instrument in the struggles for national homogeneity and sovereignty and social democracy in present-day Vietnam.

  • The purpose of the study is to find the factors that influence the financial leverage of Vietnam firms. The dependent variable is the financial leverage and the independent variables are firm size, asset structure, liquidity, growth opportunities, profitability, and firm age. The data are collected from Vietnam firms' annual financial reports in the period from 2010 to 2019. The study uses a sample of 448 Vietnam listed firms in the period. We also employ a panel regression model with pooled OLS and fixed effect to analyze the firms' financial data. The results of the model showed that financial leverage (FL) has a negative relationship with some factors such as asset structure (AS), liquidity (LQ), growth opportunities (GRW), profitability (ROA), and firm age (AGE) in the fixed effect regression. It means that when liquidity, profitability, and firm age increase, firms' financial leverage will decrease. While firms' financial leverage has still a positive relationship with the firm size (SIZE) in the model. As a result, when firm size increases, financial leverage will increase, too. The results showed that models are fit for the research and can be used to predict future findings. It is also useful for enterprises, financial advisors, investors, as well as the financial managers.

  • This study aimed to explore the factors affecting the innovation capacity of students at the National Economics University, Vietnam. Researchers used the innovation capacity model based on six factors, including personality traits, future orientation, creative skills, social interaction, content knowledge, and management skills. The empirical analysis used data from the survey of 303 students at National Economics University, Vietnam, with reliable tools (SPSS 26.0 software). The data were analyzed by testing the reliability of the scales, correlation analysis, and Pearson' Linear Correlation Coefficient, exploratory factor analysis, as well as regression model based on the survey data. The research results identified the following factors affecting innovation capacity of students: management skills, social interaction, and personality traits have the strongest impact on innovation capacity of students; content knowledge has the following strongest effects on innovation capacity of students; and finally the creative skills that affects on innovation capacity of students. There is also a positive relationship between all the factors and innovation capacity of students. The result can serve as useful reference sources for scholars who are interested in the innovation field. It also helps university's managers and policymakers build the appropriate environment to improve innovation capacity of students.

  • Traditional procurement methods have revealed many disadvantages in construction fields such as the adversarial relationships between stakeholders. After several decades of application, partnering has shown to be an innovative arrangement that helped to reduce many problems existing in the traditional arrangement. In Vietnam, partnering has been applied for construction projects since the construction industry was facing many new challenges emanated from the global integration and economic booming. Partnering is rather new, so it needs to gain a better understanding of the new concept. This paper has identified twenty eight success factors for partnering in the Vietnamese construction industry. Five factors are considered critical to partnering success including financial security, commitment from top management, mutual trust between parties, adequate resources and effective communication. The findings could help construction practitioners to deploy the innovative procurement type and would also contribute to the global knowledge.

  • The study investigates the impact of globalization on coal consumption in Vietnam. This study employs an autoregressed distributed lag approach on time series data for the period of 1990 to 2017. The study tests the stationary, cointegration of time series data and utilizes autoregressed distributed lag modeling technique to determine the short-run and long-run relationship among coal consumption, globalization, income, population, and CO2 emissions. The results show that globalization increases coal consumption in Vietnam in the long run. The results also show that rapid economic growth promotes more coal consumption in the short run as well as in the long run. Moreover, higher population reduces coal consumption, and CO2 emissions decrease coal consumption both in the short run and the long run. The findings of the study suggest that globalization increases coal consumption in Vietnam in the long run. This result suggests that the increase in globalization level in Vietnam increases coal consumption. An interesting finding is that higher population reduces coal consumption, and population is an important factor towards the lessening in coal consumption. The findings confirm that environmental pollution decreases coal consumption in the short run and the long run. This implies that coal consumption may be green consumption in Vietnam.

  • The taxonomic status and the distribution of Rosenvingea species need attention because of the difficulties in morphological identification in the laboratory as well as in the field. We analyzed mitochondrial cox3 and plastid psaA gene sequences from Rosenvingea species from Vietnam, Mexico and Panama in combination with morphological examinations. Our results confirmed the occurrence of R. intricata and R. orientalis in Vietnam. R. intricata formed dense decumbent mats with many flat branches, often inter-adhesive, and was up to 5 cm in diameter. R. orientalis thalli were up to 18 cm long with narrow (less than 2 mm in width) tubular to compressed fronds. Both cox3 and psaA phylogenies revealed the non-monophyly of the genus Rosenvingea, as reported previously for other scytosiphonacean genera.

  • This paper provides the practical application of a linear shrinkage framework on Vietnam stock market. The cumulative data points observed in this analysis are 468 weeks from January 2011 to December 2019. All the companies listed on Ho Chi Minh City Stock Exchange (HOSE), except the companies under two years period from Initial Public Offering (IPO), are considered. The cumulative number of stocks picked is therefore 350 companies. The VNINDEX, which is the Vietnam Stock Index, is used as a reference index for shrinking to a single-index model. The empirical results show that the shrinkage of covariance matrix for portfolio optimization gives the promising results for the investors on Vietnam stock market. The shrinkage method helps the investors to produce the optimal portfolio in the sense of having higher profit with lower levels of risk compared to the portfolio of the traditional SCM method. Moreover, the portfolio turnover of shrinkage method is always kept at low magnitudes, and this makes the shrinkage portfolios save much transaction costs and reduce the liquidity risks in the trading process. In addition, the ability of shrinkage method in making profit is once again confirmed by the Alpha coefficient that achieves a high positive value.
