The gender wealth gap by household head in Vietnam

While the gender income gap has been examined extensively, the gender wealth gap has largely been ignored, especially for emerging markets such as Vietnam. The lack of serious analysis has caused great concern for practitioners and policymakers as public policy targeting the inequality in income and wealth across genders has not achieved their desired outcomes. Previous studies on gender in emerging markets have focused on income rather than wealth. This paper provides a comprehensive review and insightful policy recommendations on the important issue. Using data from Vietnam's Household Living Standard Survey (VHLSS), the paper examines the gender wealth inequality for sole-head families and partner-head families in Vietnam in 2016, the latest year for which data are available. In addition, the paper extends the Machado-Mata decomposition technique based on the Oaxaca-Blinder decomposition, which was developed for quantile regressions, to examine the relationship across the distributions of wealth accumulation. The empirical findings from the paper indicate that, among partnered heads, female-head families experienced a larger gap of wealth accumulation. At the lower quantiles of wealth accumulation, the gender wealth gap is primarily associated with different characteristics for both sole and partner-head households. At the median and upper tails of the distribution of wealth accumulation, gender differences in endowments (such as education level and living area) are the main determinants in explaining the wealth gap. Given the empirical findings in the paper, policy implications emerge for the Vietnam Government to consider policies targeting a support for females as female-head families appear to be poorer than their male-head counterparts in terms of wealth.</p

Factors affecting the decision to choose a university of high school students: A study in An Giang Province, Vietnam

It is important to provide high school students with the necessary information for them to consult and make a decision to choose a university. The study aims to identify and evaluate the influence of factors in the decision to choose a university for high school students. The questionnaire survey method was used to collect data from 393 students from eight high schools in An Giang Province, Vietnam. Exploratory factor analysis and linear regression were used to analyze the data. The research results show that students are quite satisfied and quite certain with their decision to choose a university, while there are six important factors affecting the decision to choose a university. Influential factors with decreasing order of magnitude are: i) Factors consulted by teachers, family, friends, and relatives; ii) Factors of future job opportunities; iii) Factors of media activities; iv) Factors of learning conditions; v) Factors of university reputation; vi) Factors belong to the students themselves. The findings of the study show that there is no statistically significant difference between the group of males and females, between grades 10, 11, and 12. Besides, there is a statistically significant difference between students in high schools. The findings of this study have theoretical and practical implications for university admissions in Vietnam. Proposals made to university administrators were discussed. From the research results, we want to help students find the right university, and support universities to improve the efficiency of admissions

Source and release mechanism of arsenic in aquifers of the Mekong Delta, Vietnam

In order to elucidate the arsenic source and its release mechanism into groundwater in the Mekong Delta, Vietnam, groundwater samples were collected from wells at different depths (20 to 440 m) and core samples (from 20 to 265 m depth) were analyzed. Based on the analytical results for groundwater and core samples, the As source in groundwater is considered to be pyrite (FeS 2 ) in acid sulfate soil (ASS) under oxidizing conditions and hydrous ferric oxide (Fe(OH) 3 ) under reducing conditions. Geochemical modeling demonstrated that As (III) is the dominant species and the presence of As-bearing sulfides, Fe-bearing sulfides and oxides phases may locally act as potential sinks for As. From variation between Fe and As concentrations in groundwater samples, the release mechanism of As is: dissolution of Fe(OH) 3 containing As under reducing conditions and oxidative decomposition of FeS 2 containing As under oxidizing conditions

Innovative development of a flying robot with a flexible manipulator for aerial manipulations

This paper presents an innovative development of a flying robot or an aerial robot, with a flexible manipulator, called the Dexterous Aerial Robotic System (DFTS), for aerial manipulations, especially for inspections and reparations of various structures such as wind turbines, power lines and open gas pipelines, decorations and painting of high industrial chimneys and walls of high buildings, as well as transport and delivery of courier shipments, relocation and manipulation of assemblies and units in inaccessible or dangerous environments. The proposed DFTS consists of two independent but interconnected systems or functional units, which have two main separate functions respectively, including a basic carrying function, and a precise positioning and stabilization function. The system with a basic carrying function is actually the main flying system, the un-manned aerial vehicle (UAV); it is remotely controlled and piloted. Meanwhile, the aerial manipulation platform, called the vertical take-off and landing platform VTOL, which is an active flying platform with 6 degrees of freedom (DOF) is used for positioning and stabilization; and it is attached to the UAV via the soft link. With the use of a long soft link, the problems which are caused by the air turbulent flows generated by the UAV are minimized, and the aerial manipulations of objects are safely controlled and operated. The VTOL which is equipped with a grasping mechanism was successfully developed, prototyped and tested. The experimental results showed that, the developed VTOL can self-stabilize with the inclination angle of being up to 8 degrees
