Dragon by the Tail, Dragon by the Head, Bilateralism and Globalism in East Asia

In this paper, we examine the bilateral implications of regional and global trade arrangements in the East Asian context. Using a dynamic global CGE model, we examine a variety of trade scenarios, in terms of bilateral relations between China and two of its most populace regional partners, Vietnam and Japan. Given the differences between the latter two economies, it might be reasonable to expect divergence in the bilateral outcomes. Our findings indicate that differences in initial conditions can indeed have a significant impact on bilateral adjustments, and that these can be adverse for some partners in the absence of policies that promote trade complementarity. By the latter we mean bilateral import and export patterns where the aggregate grows faster for each country than their total trade, but which help sustain bilateral balance of payments equilibrium.Dragon; Head; Bilateralism; Globalism

Vietnam’s Accession to the World Trade Organization: Economic Projections to 2020

This study presents a set of assessments of the long term economic effects of Vietnam’s accession to the WTO. Generally speaking, our results indicate that Vietnam would benefit from accelerating its participation in more open multilateralism. However, it is also clear from our analysis that these benefits will remain modest in the absence of comprehensive and complementary domestic economic reforms. Passive external liberalization, even when coupled with determined domestic reform, is inferior to WTO participation combined with negotiated market access and other activist multilateral agreements. Finally, our analysis shows that capital insufficiency is a very serious constraint on Vietnamese economic growth and diversification. Capital market reform can play an essential role in dynamic and sustained economic development for the country.Vietnam, WTO, Trade

Pedagogical Challenges in Online Teaching: A Qualitative Study on Vietnamese University Teachers of Social Sciences

In recent years, online teaching has gained significant traction in higher education institutions across the globe, primarily due to the widespread impact of the Covid-19 pandemic. Before the pandemic, online teaching was mainly associated with distance learning which aims to provide further education for in-service learners. In this context, our study aims to explore the pedagogical obstacles encountered by Vietnamese university teachers when implementing online teaching in social sciences. Employing qualitative research methods, such as snowball sampling and semi-structured in-depth interviews, the researchers gathered data from 23 university teachers specializing in social sciences across 12 public and private universities in Ho Chi Minh City, Vietnam. The findings of this investigation shed light on various pedagogical barriers that impede the teaching process, encompassing aspects such as lesson plan preparation, lecture delivery (limited interactions, teaching methods and activities, students’ distraction and passive participation, managing virtual classrooms), student assessment, and overall teaching ineffectiveness. This study contributes to the existing literature on contextualized online instructions in higher education, specifically focusing on the social sciences domain. Furthermore, the discussion delves into the critical points, providing a comprehensive understanding of the challenges faced by educators in the online teaching landscape

Hematological parameters of red tilapia (Oreochromis sp.) fed lemongrass essential oil (Cymbopogon citratus) after challenge with Streptococcus agalactiae

The study involved feeding lemongrass essential oil (LEO) supplements to red tilapia (Oreochromis sp.) at concentrations including Control - 0 mg, T1 – 200 mg, T2 – 300 mg, and T3 – 400 mg per kg of feed. The research investigated changes in hematological (HCT, Hb, RBC, WBC & thrombocytes) and erythrocyte’s morphological (major/minor axis; perimeter, and area of erythrocyte) parameters before infection, 5- and 10-days post-infection (DPI). According to analytical findings, a diet containing LEO enhanced the synthesis of both erythrocytes and leukocytes in the peripheral blood of red tilapia after 20 days of being used. Therefore, the indicators of this group of fish showed better performance than those that did not use LEO supplement five days after bacterial infection. Fish fed 200 mg/kg of LEO after being challenged with S. agalactiae for ten days showed an improved effect on red blood cell production. White blood cells decreased at all concentrations because of citral’s immunomodulatory properties

Straightforward Procedure for Laboratory Production of DNA Ladder

DNA ladder is commonly used to determine the size of DNA fragments by electrophoresis in routine molecular biology laboratories. In this study, we report a new procedure to prepare a DNA ladder that consists of 10 fragments from 100 to 1000 bp. This protocol is a combination of routinely employed methods: cloning, PCR, and partial digestion with restriction enzymes. DNA fragments of 100 bp with unique restriction site at both ends were self-ligated to create a tandem repeat. Once being cloned, the tandem repeat was rapidly amplified by PCR and partially digested by restriction enzymes to produce a ladder containing multimers of the repeated DNA fragments. Our procedure for production of DNA ladder could be simple, time saving, and inexpensive in comparison with current ones widely used in most laboratories

Development of Daphnia magna under exposure to the xenobiotic octylphenol: Research article

Xenobiotics are of human and environmental concerns due to their potential toxicity. Octylphenol is one of the very common and daily used xenobiotics in door and out door activities of human beings. Toxicity of octylphenol to aquatic organisms, especially to zooplankton (e.g. Daphnia magna) was investigated but not fully understood. In this study we evaluated the chronic effects of octylphenol at the concentrations of 5, 50 and 500 μg L-1 on Daphnia magna over a period of 14 days. The results showed that low concentration of octylphenol (5 μg L-1) stimulated the maturation while high concentrations of the chemical (50 and 500 μg L-1) caused a significant mortality to the Daphnia. Besides, all the tested concentrations of octylphenol had serious impacts on fecundity and growth of the animals. Investigations on the presence, distribution, fate and toxicity of xonobiotics including octylphenol in the developing country environment are suggested for human, environmental and ecological health protection.Những hợp chất tổng hợp đang là mối quan ngại cho con người và môi trường vì khả năng gây độc của chúng. Octylphenol là một trong những hợp chất tổng hợp được sử dụng phổ biến và thường xuyên trong những hoạt động của con người trong nhà và ngoài trời. Độc tính của octylphenol đối với thủy sinh vật, đặc biệt đối với động vật phù du (vd. Daphnia magna) mặc dù đã được nghiên cứu nhưng vẫn chưa được hiểu biết đầy đủ. Trong nghiên cứu này, chúng tôi đánh giá ảnh hưởng mãn tính của octylphenol ở các nồng độ 5, 50 và 500 μg/lít lên Daphnia magna trong thời gian 14 ngày. Kết quả cho thấy ở nồng độ octylphenol thấp (5 μg/lít) kích thích sự thành thục của sinh vật trong khi ở nồng độ cao hơn (50 và 500 μg/lít) gây chết đáng kể Daphnia. Bên cạnh đó, tất cả các nồng độ ocytlphenol dùng trong thí nghiệm gây ảnh hưởng nghiêm trọng lên sức sinh sản và sinh trưởng của sinh vật. Nghiên cứu về sự hiện diện, phân bố, phát tán và độc tính của những chất tổng hợp bao gồm octylphenol ở các nước đang phát triển nên được tiến hành vì mục tiêu bảo vệ sức khỏe con người, môi trường và hệ sinh thái
