Efforts to reduce tobacco use among school children need to be based on understanding of access to cigarettes by these subjects because previous studies indicated that enforcement of laws for controlling tobacco sales seems to not affect teen/school children because they can obtain cigarettes from different sources. This paper aims to describe access to and availability of cigarettes among school students (aged 13-15 years old) according to the data from GYTS Vietnam 2014. In GYTS, a national school-based survey of students of grades 8-10, our findings showed that about 15% school children are current smokers who smoke at home, and that they could easily buy cigarettes from stores (63.2%), or someone else (27.8%), or street vendors (9%). Notably, over 85% of school children answered that they were not refused because of their age. This high percentage was nearly the same in the North (85.7%), the Centre (92.5%), and the South (89.7%) of Viet Nam. These findings show that it is quite easy for school children to obtain cigarettes and this is a crucial challenge for policy makers aiming to reduce tobacco use among youth in general and school-age students in particular.

<P><B>Abstract</B></P> <P>This study investigated the microstructure, dielectric, ferroelectric, and strain properties of lead‒free 0.995Bi<SUB>1/2</SUB>(Na<SUB>0.82</SUB>K<SUB>0.18</SUB>)<SUB>1/2</SUB>TiO<SUB>3</SUB>–0.005BaZrO<SUB>3</SUB>/0.98Bi<SUB>1/2</SUB>(Na<SUB>0.78</SUB>K<SUB>0.22</SUB>)<SUB>1/2</SUB>TiO<SUB>3</SUB>–0.02LaFeO<SUB>3</SUB> (BNKT18BZ/BNKT22LF) ceramic composites. We found that the required electric field for trigging the phase transition from ergodic relaxor (ER) to ferroelectric of BNKT18BZ/BNKT22LF ceramic composites can be effectively decreased by adding BNKT18BZ as nonergodic relaxor (NER) with changes of three different stabilized regions and the highest <I>S</I> <SUB>usable</SUB> peak points as a function of the applied electric field. The highest <I>d</I> <SUB>33</SUB> <SUP>*</SUP> value of 690p.m./V was obtained at 4kV/mm for 0.3wt BNKT18BZ fraction ceramic composites. This value was higher than 575 p.m./V of BNKT22LF ceramics under an applied electric field of 5kV/mm.</P>

Abscisic acid (ABA) is a phytohormone essential for seed development and seedling growth under unfavorable environmental conditions. The signaling pathway leading to ABA response has been established, but relatively little is known about the functional regulation of the constituent signaling components. Here, we present several lines of evidence that Arabidopsis Raf-like kinase Raf10 modulates the core ABA signaling downstream of signal perception step. In particular, Raf10 phosphorylates subclass III SnRK2s (SnRK2.2, SnRK2.3, and SnRK2.6), which are key positive regulators, and our study focused on SnRK2.3 indicates that Raf10 enhances its kinase activity and may facilitate its release from negative regulators. Raf10 also phosphorylates transcription factors (ABI5, ABF2, and ABI3) critical for ABA-regulted gene expression. Furthermore, Raf10 was found to be essential for the in vivo functions of SnRK2s and ABI5. Collectively, our data demonstrate that Raf10 is a novel regulatory component of core ABA signaling.

NGUYEN, Hanh Thi Hong,TRAN, Ngoc Minh,NGUYEN, Quyen Le Hoang Thuy To Korea Distribution Science Association 2020 The Journal of Asian Finance, Economics and Busine Vol.7 No.10

This paper explores the barriers to derivative accounting disclosures in Vietnamese companies and ranks their relative importance for effective and efficient remedies. The Delphi technique was applied to get agreement of panel of experts on the measurement of factors hindering disclosure. Unstructured questionnaires were first sent to twelve experts who had both practical experience and academic knowledge in the field to get ideas on the obstructions to derivatives disclosure. The structured questionnaire was designed to get their agreement on barriers to derivative accounting disclosures. The data analysis with mean, median, mode, standard deviation, and quartile has been implemented to ensure the unanimity. Market-related factors, legislation, accountants' attributes, managers' attributes, information technology and communication, and on-site training were the six major obstacles agreed upon by the experts during their in-depth interviews. Then, these factors were ranked by applying the analytical hierarchy process (AHP). The findings confirmed the priority of information technology and communication, which held the greatest weight. Legislation ranked second, followed by market-related factors and on-site training, which explained the impediments to derivatives disclosure. Managers' and accountants' attributes had the least contribution to the barriers to derivative disclosures. The results have important implications for actions to enhance corporate derivative disclosures in Vietnam.

DINH, Hien Thi Thu,CHU, Ngoc Nguyen Mong,TRAN, Van Hong,NGUYEN, Du Van,NGUYEN, Quyen Le Hoang Thuy To Korea Distribution Science Association 2020 The Journal of Asian Finance, Economics and Busine Vol.7 No.12

Employability has recently become the first target of the national higher education. Its model has been updated to catch the new trend of Industry 4.0. This paper aims at analyzing and ranking the determinants of undergraduate employability, focusing on business and economics majors in Ho Chi Minh City, Vietnam. In-depth interviews with content analysis have been primarily conducted to reach an agreement on a key group of factors: human capital, social capital, and identity. The Stochastic Fractal Search Algorithm (SFSA) is then applied to rank the sub-factors. Human capital is composed of three major elements: attitude, skill, and knowledge. Social capital is approached at both structural and cognitive aspects with three typical types: bonding, bridging, and linking. The analysis has confirmed the change of priority in employability determinants. Human capital is still a driver but the priority of attitude has been confirmed in the contemporary context. Then, social capital with the important order of linking, bridging, and bonding is emphasized. Skill, knowledge, and identity share the least weight in the model. It is noted that identity is newly proposed in the model but a certain role has been found. The findings are crucial for education strategies to enhance university graduate employability.

Education policy is a dynamic process featuring social development trends. The world countries have focused their education program on empowering the learners for future life and work. This paper aims to assess the higher education curriculum based on a survey of 280 students, employers, alumni, and lecturers in both social sciences and natural sciences in Ho Chi Minh City, Vietnam. The fuzzy decision-making method, namely the Fuzzy Extent Analysis Method (F-EAM), was applied to measure the relative weight of each parameter. Seven factors under the curriculum development have been put in the ranking. Input with emphasis on foreign language was the highest priority in curriculum development, given the expected demand of the labor market. Objective and learning outcome and teaching activities ranked second and third, respectively. The traditional triangle of teaching content, methodology, and evaluation and assessment are still proven their roles, but certain modifications have been defined in the advanced curriculum. Teaching facilities had the least weight among the seven dimensions of curriculum development. The findings are helpful for education managers to efficiently allocate scarce resources to reform the curriculum to bridge the undergraduate quality gap between labor supply and demand, meeting the dynamic trends of social development.

The Effect of Institutions on Productivity Spillovers from FDI to Domestic Firms: Evidence in Vietnam

Huynh Quoc Vu,Pham Thi Bich Ngoc,Nguyen Le Hoang Thuy To Quyen 사람과세계경영학회 2022 Global Business and Finance Review Vol.27 No.3

Purpose: The purpose of this study is to investigate the impact of formal institutions and their components on productivity spillovers from FDI enterprises to domestic firms’ TFP in developing countries like Vietnam. Design/methodology/approach: The study, conducted in two steps to explore the relationship, is to estimate the firm's TFP in accordance with the semi-parametric method of Levisohn and Petrin (2003). Regression is in accordance with the equation with panel data and adjusted by Driscoll and Kraay standard errors. An unbalanced panel data, related to more than 61,600 Vietnamese manufacturing firms from 2012 to 2017, is combined with the Provincial Institutional Quality Survey (PAPI index) and IO table. Findings: The local institutions have a positive impact on promoting learning ability and increasing productivity of domestic firms, especially small and medium enterprises (SMEs) that take better advantage of this effect. Vertical linkages with FDI enterprises assist local firms to increase productivity while horizontal linkages bring in negative effects. Domestic enterprises with high productivity (in the top 25%) receive positive spillover effects from horizontal linkages and vertical linkages and gain positive impacts of the institution on productivity whereas the group of low-productivity enterprises records negative impacts. This research highlights those enterprises operating in the region where institutions have transparency, accountability, participation in comments and effective corruption control can absorb spillovers and improve their productivity as well as the transparency and corruption control are recognized as having a positive impact through horizontal linkages. Research limitations/implications: With the limitation of research data being conducted only on manufacturing enterprises, there is a lack of data on the impact of service enterprises. The study only stops at understanding the impact of formal institutional effects on productivity spillovers whereas informal institutional effects will be studied in the future. Furthermore, the productivity spillovers of FDI enterprises are explored in general besides other FDI forms that will have different productivity spillovers like offshore. From the results of this study, the governments of developing countries should improve their institutions to encourage local enterprises to take the advantage of spillover effects from FDI enterprises as well as pay more attention to regional factors by supplementing development priority policies based on the capacity of each region. Institutional quality at provincial level has a positive impact on productivity spillovers; consequently, it is essential to have policies for further institutional improvement. Originality/value: This is the first research paper on the impact of the institutional factor at provincial level on firm’s productivity in developing countries like Vietnam. Theoretically, the impact of formal institutions on spillover effects from FDI enterprises is also clarified. In addition, our findings have implications for local economic development policies: vertical linkages promote domestic firms to increase their productivity while horizontal linkages of FDI enterprises in the same industry generate adverse impacts. This paper suggests some feasible solutions for SMEs in developing countries towards their productivity improvement.
