APPLYING THE CASE METHOD IN TEACHING THE DEPARTMENT OF DEFENSE AND SECURITY EDUCATION AT THAI NGUYEN HIGH SCHOOL, VIETNAM

The case method is a teaching method based on real-life events that have happened or are happening. This method is based on constructivist theory and geared toward the target: education as preparation for solving life situations. Learning through solving situations helps students actively and strategically receive knowledge, flexibly apply knowledge and skills, and develop problem-solving abilities. By observing, interviewing, and experimenting, the article has developed a process of organizing case teaching and applied it in teaching National Defense and Security Education at Thai Nguyen High School, Vietnam. Initial results show that the percentage of students interested in the lesson is high (85%). That shows that the effectiveness of the method is feasible and creates a basis for continuing to use this teaching method in practice.  Article visualizations

Dealing With Non-Performing Loans During The Bank Restructuring Process in Vietnam: Assessment Using The AHP and TOPSIS Methods

This article aims to assess the solutions that have been implemented in Vietnam to deal with non-performing loan(s) (NPLs) in the banking system. By trying to build evaluation criteria through a literature review and an expert survey, as well as using the analytic hierarchy process (AHP) and technique for order preference by similarity to ideal solution (TOPSIS), this research measures the effectiveness of the resolution of NPLs in Vietnam through many factors. The empirical results show that, in the past, the banking system in Vietnam has not dealt very well with bad debt, as it mostly uses traditional methods such as NPL write-offs by loan loss reserves or the liquidation of collateral. Based on our consideration of the NPLs’ resolutions that the Vietnamese banking system has implemented recently, we propose some suggestions to improve the necessary conditions for applying more market-based solutions, such as debt-equity swaps and securitization to thoroughly resolve the NPLs in Vietna

ASSESSMENT OF EFFECTIVENESS TO REDUCE GREENHOUSE GAS EMISSION OF BIOGAS DIGESTERS IN LIVESTOCK MANURE TREATMENT AT VAN CU RICE NOODLE CRAFT VILLAGE, THUA THIEN HUE PROVINCE

This paper used some calculation techniques of IPCC to quantify the economic and environmental benefit from greenhouse gas (GHG) emission mitigation at Van Cu rice noodle craft village, Huong Toan commune, Huong Tra town, Thua Thien Hue province. The resulting calculation showed that the GHG emission amount of Van Cu rice noodle craft village was 1,572.3 tonnes of CO2e/ year, in which the GHG emission of households who had activities of swine breeding and rice noodle producing had accounted for 78% of total emissions of the whole village. There were 24 biogas digesters in 31 households had built biogas works that were working well and creating biogas for usage as fuel to service of life. Therefore, this study surveyed at 24 households were using biogas works efficiency. Before using biogas works, average GHG emission reached 51.0 tonnes CO2e/ household/ year. After using biogas digesters, total GHG emission of 24 households reduced 267.6 tonnes of CO2e/ year. Thus, the total GHG emission amount was cut down 956.5 tonnes of CO2e/ year, corresponding to revenue from the sale of certified emission reductions (CERs) was 13.04 million dong/ year

Shifting views on irregular migration during a time of socio-political change: A critical analysis of press and social media discourses in the UK, 2015 - 2018

The cross-border movement of people repeatedly leads to political controversy in countries across the world. In Europe, migration became a paramount public concern after the arrival of the unprecedented number of 1.2 million migrants in 2015. Most of these individuals were labelled ‘irregular’ due to their lack of valid travel documents. European states have various policy measures in place to combat irregular migration. In particular, the United Kingdom has a long-standing tradition of restrictive policies since the mid-1960s. However, little knowledge exists on public views towards irregular migrants and how people regard the state’s responses, with most previous research limited to newspaper analyses. These studies emphasised a widespread negative portrayal of migrants as cultural and security threats. Social media presents an additional rich source to traditional media, but its potential to unveil the public discourse on irregular migration remains largely untapped. This research examines the online press and social media discourse on irregular migration between 2015 and 2018 in the British context. This time period is significant as it covers the heightened public interest in migration following the so-called ‘migration crisis’ in Europe. Moreover, migration was a crucial factor influencing the outcome of the British EU referendum in 2016. Both events are expected to have caused an increasing interest in migration among the online press and social media users. The study is based on an analysis of 244 online newspaper articles and 22,967 corresponding social media comments. Using Social Identity Theory and Social Representation Theory, this thesis explores the discursive organisation of group-thinking dynamics and shared social identity of three key social groups - migrants, nationals and government of migrants’ destination country - and asks how they are depicted by ingroup and outgroup representations. The key contributions of this thesis are twofold. First, this study is among the first to analyse both press representations and people’s views expressed about irregular migration on a social media platform over a long time span. By employing this approach, this study highlighted that the press and social media discourse on irregular migration was highly volatile, shifting with the changing socio-political events between 2015 and 2018. Second, in-depth analysis of social media comments revealed that strong opposition to irregular migrants was shown to be primarily used as a vehicle for commenters to express their dissatisfaction and lack of trust in the political handling of irregular migration and of the citizens’ concerns. These ingroup and outgroup dynamics highlight a paradox in which British policymakers have created a hostile image of irregular migrants but fail to understand the respective doubts and expectations of the British public. Political elites should reassess the way they represent and address irregular migration in light of these findings

SEASONAL VARIATION OF PHYTOPLANKTON FUNCTIONAL GROUPS IN TUYEN LAM RESERVOIR, CENTRAL HIGHLANDS, VIETNAM

Seasonal changes in freshwater phytoplankton assemblages at Tuyen Lam Reservoir in the Central Highlands of Vietnam were classified into 23 functional groups based on physiological, morphological, and ecological characteristics. A total of 168 species were recorded during 10 surveys from 2015 to 2019 at 7 sampling sites, with Chlorophyta dominating in number of species. Phytoplankton abundance varied from 0.18×105 to 21.2×105 cells/L during the study period, mainly due to cyanobacteria. Seven of the 23 functional groups were considered to be dominant (relative density > 5%).  The dominant functional groups were groups M and G in the dry season and groups M, G, P, and E in the rainy season. Group M (Microcystis aeruginosa) was the most common in both seasons, while group P (Closterium, Staurastrum, Aulacoseira), group E (Dinobryon, Synura), and group G (Sphaerocystis, Eudorina) were more common in the rainy season. The Shannon diversity index (H¢) showed that phytoplankton communities were relatively diverse and that most of the study sites were lightly polluted. However, the ecological status has deteriorated at some locations due to the overgrowth of group M, leading to eutrophication in this reservoir. This study highlights the usefulness of functional groups in the study of seasonal changes in phytoplankton dynamics. Functional groups are applied for the first time at Tuyen Lam Reservoir and can be used to predict early-stage cyanobacterial blooms in future studies

The Efficiency and the Performance of the Logistics Global Supply Chain Activities to Vietnam Exportation: an Empirical Case Study

Purpose: This research paper aims to determine the factors affecting the efficiency and logistics performance index (LPI) of Vietnam's exports to foreign partners during 2018-2022 are due to the impact of the COVID-19 pandemic.   Theoretical Framework: Based on the primary factors affecting the efficiency and performance of global supply chain activities in logistics for Vietnam's exports, including practical impact and logistics results of enterprises in Vietnam. Based on the primary factors affecting the efficiency and performance of global supply chain activities in logistics for Vietnam's exports, including (1). Customs efficiency (speed, simplicity and predictability of customs clearance procedures) (2). Quality of infrastructure related to trade and transport, including Roads, railways, ports, airports, warehouses and information technology ...(3). The level of ease when arranging to transport import and export goods with competitive prices (costs such as warehousing fees, port fees, tolls ... ) (4). Capacity and quality of logistics service providers ... (5). Ability to track and trace shipments. (6). Timeliness of the shipment to the destination within the specified time limit. The practical impact and logistics results of enterprises in Vietnam.   Method: The panel approach allows the authors to explore the heterogeneity in data across countries. Fixed effects (FE) and random effects (RE) models were used to estimate the model. Then, the Hausman test is carried out to decide which model is appropriate. The data were collected from 240 observations from Vietnam and 80 major export partner countries of Vietnam.   Findings: The research results show that the cost, time and capacity of providing logistics services have the most significant impact on Vietnam's exports.   Practical & social implications: Overall, to increase the efficiency and logistics efficiency of enterprises. The Vietnamese Government needs to cooperate and propose ideas to partner countries to improve logistics activities for exports from Vietnam. Logistics is beginning to play an increasingly important role in the competitiveness of economies.   Originality values: This study also confirms the sustainability of the extended gravity model using OLS and RE methods by substituting different variables for the country's logistics efficiency and solving the endogenous problem in the model while applying the regression method to industrial variables. We find that an 1% improvement in Vietnam's logistics would increase Vietnam's exports by 1.443%, and an 1% improvement in a partner country’s performance would help promote Vietnam's exports to this country by 0.546%
