Quynh Nga DUONG,Thanh Binh VU,Thi-Phuong VO,Ngoc Hoan NGUYEN-LE,Van Diep NGUYEN 한국유통과학회 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.6
The purpose of the research examines the relationship between foreign ownership and listed firms’ performance in Vietnam. This study employs an extensive set of panel data comprising 288 non-financial listed Vietnamese firms, over a period from 2015 to 2019 taken for analysis. The results show that the higher the foreign ownership ratio, the higher the performance, however, the relationship between foreign ownership and firm’s performance is U-shaped. In contrast, when the foreign ownership ratio is becoming too high, it will reduce the firm’s performance and firm size, liquidity, financial leverage, capital intensity, and growth opportunities. Furthermore, we find that foreign ownership and performance are linked by an inverted U-shaped relationship. A firm’s performance increases with greater foreign ownership up to the range of 36.26%, and declines thereafter. The paper also found positive effects of firm size and growth opportunities, and an inverse relationship between liquidity, financial leverage and capital intensity, and firm’s performance. This study has several implications for the enhancement of information and understanding of the foreign ownership as it sheds light on the foreign ownershipfirm’s performance relationship. Moreover, the study findings contribute to the literature concerning the ownership structure in the context of developing countries.

Project manager plays a very important role in the success of any project. The primary duty of the project manager is to combine the outcomes or results of the various processes and activities of project management into a systematic project management strategy or plan for the project. In the construction industry, a lack of motivation is an urgent problem for many project managers in construction and engineering projects. Lack of motivation affects the quality and productivity of jobs, reducing profits and growth for companies, businesses, contractors or organizations that rely on human resources. The reasons for this lack of motivation are diverse ranging from salary to culture to life and working environment, among others. Through surveys and data analysis using Cronbach's Alpha reliability and EFA (Exploratory Factor Analysis), our research scaled the factors affecting work motivation of project managers in the construction industry in Vietnam. The research results identified six major groups of relevant factors including (i) salary and benefits, (ii) work environment, (iii) promotion opportunities, (iv) organizational culture, (v) interest in the job, and (vi) relationship with the organization. From there, this paper contributed useful information as well as measures for businesses, companies, contractors or organizations in the construction industry.

Livelihood capitals have a clear influence on livelihood development. As for the livelihood results, it has been pointed out in the analysis of the poor households that the ability of people to escape poverty depends especially on the access to livelihood capitals. This study aims to analyze the impacts of livelihood capital on poverty among mountain people who depend on forests through human capital, social capital, natural capital, physical capital and financial capital. This research employs the model of binary regression function. Independent variables x1, x2, …, xn are targets of livelihood strategy, vulnerability context, and livelihood capitals. These variables were selected to be included in the original model with dependent variable Y as poor and non-poor households. This study surveys households living in upland areas, near forests, and households of ethnic minorities. The results show that,out of the poor household rate, nearly 4% are newly-poor households or those falling back into poverty. Therefore, the government needs to pay more attention to this disadvantaged group and implements policies such as education and training policies, credit support policies, policies to support forest development, and payment for forest environmental services in the context of emerging countries like Vietnam.

In this paper, we consider the Robin-Dirichlet problem for a nonlinear wave equation of Kirchhoff-Carrier type with a viscoelastic term. Using the Faedo-Galerkin method and the linearization method for nonlinear terms, the existence and uniqueness of a weak solution are proved. An asymptotic expansion of high order in a small parameter of a weak solution is also discussed.

The study’s goal is to determine how factors affecting tourism resilience during the COVID-19 pandemic affect Ho Chi Minh Tourism’s ability to respond to changes and disruptions. The model and research hypotheses were tested using Multiple Regression Analysis Models. The statistical findings showed that the tourism resilience components have a significant influence on the tourism resilience in Ho Chi Minh city. The analyses revealed that tourism resilience consisted of four latent dimensions. There are 4 explanatory variables with a significance coefficient < 0.05. Therefore, the variables Economic resilience, Ecological resilience, Institutional resilience, and Social resilience all have a significant impact on tourist resilience, which is consistent with Jamaliah and Powell (2017). The findings have important managerial implications for local governments, as well as factors that contribute to tourism resilience, as they must attempt to adapt to changes and turbulences during a pandemic, ensuring that the tourism system rebounds in the future. The four components of tourist resilience are defined in the theoretical contribution. The findings of the study could serve as a starting point for developing future tourist resilience strategies. Because the application of tourist resilience theory is still relatively new, this study presents two theoretical and methodological contributions.
Preparation and characterization of silicone resin nanocomposite containing CdSe/ZnS quantum dots

<P><B>Abstract</B></P><P>We report the preparation of the core/shell cadmium selenide/Zinc sulfide quantum dots (CdSe/ZnS QDs)‐silicone resin nanocomposite through the solution‐mixing method, followed by thermal hydrosilylation. After dispersing QDs into Dow Corning two‐component silicone resins (OE6630A and OE6630B at 1:4 mixing ratio by weight), the resins were cured at 150°C for 1.5 h to produce QD‐silicone resin nanocomposites. The curing behavior of the silicone resins resulting from the thermal hydrosilylation was studied using differential scanning calorimetry (DSC). The properties of the QD‐silicone resin nanocomposites were investigated by ultraviolet–visible (UV–vis), fluorescence, confocal laser scanning microscopy (CLSM), atomic force microscopy (AFM), and thermogravimetric analysis (TGA) measurements. The QDs that contain trioctylamine (TOA) as the original ligand can poison the Pt catalyst in the resins and inhibit the curing process by increasing the exothermic peak temperature, at which a lower heat of hydrosilylation is observed. Incorporating a small amount of CdSe/ZnS QDs (0.1 wt%) can greatly improve the thermal stability of the silicone resins. Moreover, CdSe/ZnS QDs tend to form clusters that are relatively homogeneously distributed in a cured silicone resin, offering good optical properties of 11.2 lm W<SUP>−1</SUP> luminous efficiency and 14.6% photoluminescence conversion efficiency (PCE) in light emitting device (LED) test.

<P>The structurally well-defined diblock copolymer, poly(methyl methacrylate)-b-poly(N-isopropylacrylamide) (PMMA-b-PNIPAM) amphiphilic diblock copolymer was successfully grafted onto the surface of Halloysite nanotubes (HNTs) via reversible addition-fragmentation chain transfer (RAFT) polymerization. In this approach, S-benzyl S'-trimethoxysilylpropyltrithiocarbonate was first immobilized onto the HNTs as the RAFT agent. The polymerization of MMA and NIPAM was then initiated and propagated on the HNTs surface by RAFT polymerization. The chemical structure and morphology of diblock copolymer grafted onto the HNTs surface were ascertained by FT-IR, and FE-SEM analyses. A moderate degree of functionalization of HNTs by polymer chains was obtained according to TGA results. This study has suggested a facile approach to prepare surface functionalized HNTs via RAFT polymerization, which is promising to open up a wider prospect for the fabrication and novel application of hybrid polymeric materials with diverse functionalities.</P>

<P>In this study, a facile method for synthesis of conducting polymer/inorganic oxide hybrid nanocomposites, the poly(N-vinylcar bazole)/Titanium Dioxide (PVK-g-TiO2), was successfully developed via direct facile esterification reaction under extremely mild conditions. The TiO2 nanoparticles (TiO2 NPs) were first modified by 3-glycidoxypropyl trimethoxysilane in order to prepare the epoxy groups functionalized TiO2 NPs, followed by refluxing with ethanol solution of hydrochloric acid to convert the epoxy groups into alkyl-hydroxyl units. A sufficient amount of PVK was then grafted onto the as-modified TiO2 NPs via esterification reaction between the alkyl-hydroxyl units at the nanoparticle surface and the carboxyl-terminated PVK chains. Fourier transform infrared spectroscopy, Energy dispersive X-Ray, X-ray diffraction and thermogravimetric analysis were used to study the chemical and physical properties in surface functionalities.</P>
