Sandy soils in south central coastal Vietnam: their origin, constraints and management
No full textIn Vietnam, sandy soils are distributed mainly in the coastal central provinces where they occupy 337,768 ha comprising 63 % of the nation’s sandy soils, and they are also important to regional economic growth where more than 10 million people are living i.e.14 % of the Vietnamese population. The sandy materials in the central coastal Vietnam originate from mostly in situ weathering of granite although aeolian sediments are parent materials for sandy soils also. Sandy soils have a wide range of limiting factors for agricultural production, including nutrient deficiencies, acidity, low water holding capacity and wind erosion risk (on coastal dunal sands). Although there are soil fertility constraints to the use of sandy soils in Vietnam, 79,076 ha has been utilized in agriculture. Developing integrated nutrient management practices are needed to improve soil physical, chemical and biological fertilities of sandy soils. For example, systematic use of farmyard manures, crop residues, green manures, and alley cropping need to be considered. Developing integrated nutrient management practices also need to address environmental considerations by matching nutrient applications to crop needs and amending soils to minimise nutrient losses to water. Developing new soil management technologies (such as use of biochar, slow release fertilisers and minimum tillage) is also important for sustainable management of sandy soils in Vietnam

A Case Study of the Application of Dynamic Symbolic Execution to Real-World Binary Programs
No full textAssessing the impact of traffic climate and risk-taking attitude on the risky riding behaviour of young motorcyclists in Vietnam
No full textThis research investigates the interrelationships between traffic climate perceptions, risk-taking attitudes, and motorcyclists' riding behaviours in Vietnam using the Driver Behaviour Questionnaire (DBQ) and Traffic Climate Scale (TCS). The study, conducted among young motorcyclists aged 18-24, explores how perceptions of traffic climate, characterised by functionality, external affective demands, and internal requirements, influence risk-taking attitudes and subsequent riding behaviours. The analysis reveals that external affective demands positively correlate with higher risk-taking attitudes, whereas internal requirements are inversely related. Increased risk- taking attitudes predict frequent riding errors, violations, and lapses. These findings underscore the complexity of factors contributing to hazardous riding behaviours and highlight the need for targeted interventions that address both individual attitudes and perceived traffic conditions to improve road safety. The study emphasises the critical role of traffic climate in shaping riding behaviours, providing essential insights for developing effective road safety strategies in developing countries.We express our sincere gratitude to the anonymous reviewers and the editors for their insightful and constructive feedback, which has significantly improved the quality of this research.

Heterogeneity in behavioural response to pricing policies in the transition from motorcycles to private cars in motorcycle-based societies
No full textPricing instruments are widely seen as an effective tool for reducing the travel demand for private vehicles. In contrast to developed countries, the design of pricing policies in certain developing countries is more challenging, owing to the mixed use of private cars and motorcycles. This study argues for the existence of a transitional group of motorcycle users who will switch to being car users. An investigation of the behavioural responses to a pricing policy from private car users and motorcycle users is implemented in Ho Chi Minh City, Vietnam. A propensity score-matching technique is used to identify the transitional group. The results regarding the mode choice models for various pricing policies show similar responses between the transitional motorcycle users and car users. Such characteristics of the transitional group imply that ignorance of travellers' heterogeneity may cause significant bias, especially when modelling pricing policies.This research was financed by the Special Research Fund of Hasselt University.
