Returns to Education and the Demand for Labour in Vietnam. ESRI WP506. July 2015

Using data from the Vietnam Household Living Standards Survey, this paper examines the returns to education in Vietnam in 2002 and 2010, and how these returns changed over time. Given the economic growth that took place during this time period, the relative demand for labour is also assessed in order to identify if skill-biased technical change played a role in explaining the returns to education in Vietnam at a time of exceptional economic growth. The male and female education returns displayed a linear pattern in both 2002 and 2010, with earnings rising with increased levels of education. Relative to males with no qualifications, the returns to those with a vocational training qualification or below fell between 2002 and 2010, while the economic returns to a college education and above increased. Similar results were observed for females. In relation to relative labour demand, the results indicated that the demand for all levels of education (apart from males with a high school qualification) relative to those with no qualifications grew between 2002 and 2010. However, there was particularly strong growth in the demand for those with a vocational training qualification and above, especially an advanced degree qualification. Findings from the paper show that high levels of economic growth in Vietnam between 2002 and 2010 have facilitated increasing returns to education and demand for high skilled labour. In addition, there appears to be shortages for some types of skilled labour

MACRO-ZOOPLANKTON ABUNDANCE IN RELATION TO METAL ACCUMULATION AND WATER QUALITY IN TRUC BACH LAKE

Urban lake pollution is one of the serious issues due to suffering of waste discharged from householders. However, there is a gap of knowledge about the diversity of zooplankton species and how metals accumulate in zooplankton in urban ecosystems. We addressed this by determining the rule of blooming macro-zooplankton in Truc Bach lake and levels of two essential metals: copper (Cu), and zinc (Zn) and of three non-essential metals: arsenic (As), and lead (Pb) in water samples were determined. The results showed that Cladocerans and copepods are macro-zooplankton dominant species in Truc Bach Lake. Water temperature significantly affects the variety of copepod blooming. Arsenic concentration in water collected from the lake exceeded the safety level of current Vietnamese regulation. As concentration in macro-zooplankton positively correlated with metal concentrations in the water (p 0.05) while the concentration of Cu, Zn, and Pb in water has no significant correlation with the metal in zooplankton’s body. The relative abundance of adult copepods in Truc Bach lake had a negative correlation with As concentration in water (p = 0.01). The higher As concentration in water, the lower relative abundance of copepods was found in the sample

SOLUTIONS TO ENHANCE THE COMPETITIVE ADVANTAGE OF SMALL AND MEDIUM ENTERPRISES IN THE CONTEXT OF POST-COVID-19 PANDEMIC IN TRA VINH PROVINCE, VIETNAM

The purpose of this research is to find solutions to enhance the competitiveness of small and medium-sized enterprises in the context of the Post-Covid-19 pandemic in Tra Vinh Province, Vietnam, by collecting secondary data from reports from Tra Vinh Provincial People’s Committee, Tra Vinh Department of Planning and Investment, and Tra Vinh Provincial Statistics Office in the period 2016-2020. The authors used descriptive statistics, synthesis, analysis, evaluation, and expert surveys to verify former hypotheses about small and medium-sized enterprises and search for feasible solutions to enhance the competitiveness of small and mediumsized enterprises in Tra Vinh Province. The study analyzed the situation of small and mediumsized enterprises during the period 2016–2019 regarding the actual operation status, advantages, and limitations in the competition of Small and Medium Enterprises in Tra Vinh, Vietnam. From the research findings, the study proposes solutions to improve competitive advantages for Small and Medium Enterprises in Tra Vinh in the post-Covid-19 pandemic future

The Impact of FDI, International Trade, and National Economy on People’s Standard of Living in ASEAN Countries

This research paper analyzes the impact of foreign direct investment (FDI), international trade, and national economy on the standard of living of people in ASEAN member countries, using data from 2012-2021. The study uses data from this period to examine the effects of these variables on the standard of living in ASEAN member countries. The results indicate that international trade and national economy have a significant influence on people's standard of living in the region. However, the effect of FDI varies depending on the level of development of the country. While FDI doesn't have much effect on developing countries, it has a negative impact on developed countries. The study also provides insights for policymakers on how to promote economic growth and improve the quality of life for people in the ASEAN. Keywords: FDI, international trade, national economy, the standard of living, ASEAN DOI: 10.7176/EJBM/15-6-10 Publication date:March 31st 2023

Synthesis of new simplified hemiasterlin derivatives with α,β-unsaturated carbonyl moiety.

International audienceIn this Letter, we report a convenient and efficient method for the synthesis of new simplified derivatives of hemiasterlin in which the α,α-dimethylbenzylic moiety A is replaced by α,β-unsaturated aryl groups as Michael acceptor. Most of these derivatives have a strong cytotoxic activity on three human tumor cell lines (KB, Hep-G2 and MCF7). Analogs 17b and 17f showed a high cytotoxicity against KB and Hep-G2 cancer cell lines comparable to paclitaxel and ellipticine

Study on pathogenicity of Colletotrichum gloeosporioides on Coffee in North of Vietnam

Coffee is an important crop in Vietnam and it has recently brought a lot of benefit for the country through export. After coffee leaf rust, anthracnose is the second destructive disease for coffee production and is caused primarily by Colletotrichum gloeosporioides. In order to investigate the pathogenicity of C. gloeosporioides on coffee in the North of Vietnam, we carried out isolation of C. gloeosporioides species from different coffee plantations and found that C. gloeosporioides presents in different parts of coffee including leaf, twig, ripe berry and green berry. The pathogenicity of a total of twenty eight C. gloeosporioides isolates was tested on green berry in laboratory. Interestingly, two most pathogenic isolates were originated from green berry. In detail, the rate of green berry infection by C. gloeosporioides isolates varied from 4.44% to 76.67% and the variation of infection rate was also observed clearly among C. gloeosporioides isolates originating from leaf (14.40% to 45.56%), twig (4.44% to 58.89%), ripe berry (22.20% to 61.10%) and green berry (24.40% to 76.67%). Three selected pathogenic isolates representing for C. gloeosporioides isolates originated from twig, ripe berry and green berry were further tested for pathogenicity on hypocotyl seedling in greenhouse. The rate of hypocotyl seedling infection by C. gloeosporioides isolates originated from twig, green berry and ripe berry is 48.89%, 37.78 and 23.33% respectively. Our data suggests that pathogenicity of C. gloeosporioides is variable and specific among isolates, parts of coffee
