Abstract: Flood effects are very serious, especially in developing countries where they are at high risk due to urbanization and socio-economic development. Reliable information is crucial to support decisionmakers or planners to develop appropriate strategies to reduce flood risk. This article aims to develop a theoretical framework for assessing flood risk and adaptive capacity based on a bottom-up approach, in the Gianh River watershed of Vietnam, considered a very important task for flood risk management. Flood risk was computed by combining hazard, exposure, and vulnerability using hydrodynamic modeling and the Analytic Hierarchy Process method. The adaptive capacity of the population was assessed via interviews with 298 inhabitants. The results show that flood risk is high in areas with high population and construction density. Both the ability to access resources and communities' perceptions are important factors in improving the capacity to adapt. This study can provide an important theoretical framework complementing the existing literature and supporting studies related to flood risk management in the context of climate change and urbanization in other regions. Besides, the study fills in a gap in the knowledge of negative flood effects, providing important inputs for decision-makers to develop appropriate strategies for reducing damage in Vietnam and other countries in the world. From a methodological start point, this study underlines the importance of using hydraulic models and socioeconomic surveys in flood risk management.

Abstract: Based on a qualitative case study in An Giang province, Vietnam, we mapped the understanding of the ‘Living with Floods’ (LWF) concept and the implementation of three projects to explain the effectiveness of water governance in Vietnam. We have demonstrated how perceptions on the LWF concept differ per government level and the limits of water governance effectiveness. Diverging perceptions undermine the effectiveness of water governance. A framework and a list of indicators are proposed to measure the effectiveness of floodwater governance. Integrating local and social aspects in LWF policies and vertical coordination may help align short-term benefits with long-term adaptation.

Abstract: Study region Ganh Hao River, Ca Mau Peninsular, Vietnamese Mekong Delta. Study focus The study was conducted to determine the extent of pollution by physicochemical parameters and heavy metals through seasonally sampling of the river. The water quality was compared with international and Vietnamese standards, while sediment quality was compared with the Vietnamese standard and pollution indices (Geo-Accumulation Index, Contamination Factor, and Pollution Load Index). The principal component analysis (PCA) was employed for explaining the main factors responsible for observed levels of water pollution. The oscillations due to tidal cycles and seasonality were also evaluated by statistical comparison. Based on the logistic regression models, the temporal variability of selected water quality parameters was visualized using QGIS. New hydrological insights The results showed that the concentrations of nutrients and organic compounds exceeded the allowable standards for surface water quality. The concentrations of heavy metals were below the allowable standard for sediment quality and consistent with the background levels. The influences of the tidal regime and seasonality caused significant changes in water quality. Aquaculture practices and tidal regimes accounted for 79.84% of the total variance in water quality characteristics. The extensive and improved-extensive shrimp culture activities were identified in relation to the variation in water quality, and water quality maps highlighted pollution hotspots. The research results could be useful not only to policymakers in developing water resources management strategies but also likely widespread implications for other rivers beyond the geographical regions.

Abstract: Tidal energy is a renewable energy source produced by the rise and fall of ocean tides. Tidal energy can be exploited using a special type of generator that converts tidal energy into electricity. Tidal power generation has the potential to open up many prospects for energy field and minimize carbon dioxide emissions that cause the greenhouse effect. To evaluate the possibility of tidal power, it is necessary to have documents and data on average annual tidal amplitude, tidal regime, and main tidal waves in the study area. To calculate the tidal power potential for the east coast of Vietnam, this article applies the calculation formula of tidal power energy by Russian scientist L.B. Bernstein. The annual mean tidal amplitude and the K1, O1, and M2 wave amplitude data at nearly 2000 calculation points along the coast of Vietnam were extracted from the TPOX8- Atlas harmonic constant set. Research results showed that Vietnam has great potential for tidal energy along the Hai Phong - Quang Ninh coastal area and the southeast region with a prospective 41.6 GWh/km2/y.
Human resource development in Vietnam : research and practice
Hien Thi Tran. Cham, Switzerland : Palgrave Macmillan, 2021.
Abstract: Vietnam has had one of the highest GDP growth rates in the world in recent years, yet it remains a developing economy. There remains a need to improve factors influencing the development of its human resources through education at all levels, workplace training, corporate social responsibility, gender equality, support for entrepreneurship, and other practices and policies related to HR. Yet, national HRD, officially, is a relatively new concept in Vietnam. This edited volume highlights the importance of developing human resources, enabling Vietnam to continue its growth in its move into the ranks of developed countries. It examines the historical, political, economic, and cultural contexts embedded in HRD at national and organization levels and emphasizes the changes that HRD can bring about in the nation. This book offers scholars and practitioners a non-western view of how HRD research should be more indigenous and discusses implications for future research.
Minority Students’ Experiences are Part of Our Life of Teaching”: Hierarchical Multiple Regressions of Vietnamese Teacher Autonomous Motivation and Teacher Engagement
Ngoc Tung Vu and Duc An Nguyen. Journal of ethnic and cultural studies, 9(2), 2022. Free full text http://www.ejecs.org/index.php/JECS/article/view/949.
Abstract: This article seeks to understand teacher autonomous motivation and teacher engagement of Vietnamese in-service teachers of English working with Vietnamese ethnic minority students, by presenting their voices and experiences as a hierarchical multiple regression analysis. Relying on the Self-Determination theory (Deci & Ryan, 1985), this quantitative study draws insights into Vietnamese K-12 English teachers of ethnic minority groups, when it comes to intrinsic, external, introjected, and identified motivation in support of their continuation of daily teaching activities and their further teaching professions. These aspects are likely to be translated into their sense of engagement in their professional contexts to different extents. Applying purposeful sampling for quantitative data collection, we primarily focus on drawing from the teachers’ self-rated competence to better explore a wide range of Vietnamese education insights regarding Vietnamese minority groups. Our findings, based on the multiple rounds of hierarchical multiple regression, suggest that teacher autonomous motivation and teacher engagement appear to be closely associated. Some relevant associations are found to occur under the influence of the teachers’ demographic backgrounds, including personal, familial, and educational experiences. Pedagogical implications are also presented at the end of our study, making way for future research to continue this important scholarship.

Abstract: This paper aims to sketch a comparative review of the education of mathematical talents between Eastern and Western countries. In this study, East Asia refers to countries such as China, Hong Kong, Japan, Korea, Taiwan, Singapore, and Vietnam, and the “West” refers to North American countries and Europe. Student achievement is determined by a variety of different factors and international comparative studies would seek to identify similarities and differences in educational policies and practices, unraveling the variables underlying the different practices. Within the scope of this text, the variables construed to be related to talent development include the traditional perception of mathematical giftedness, the identification regime, gifted curriculum and teacher capacity. The strengths and weaknesses of each of the systems will be discussed in light of educational perspectives regarding mathematical talent education. The second half of the text examines a specific case of Vietnam, a country with impressive achievements in international Math competitions. Discussion will focus on Vietnam’s mathematical successes and contributions in local and international contexts, as well as the future fostering of brilliant children in mathematics.
