Factors affecting corruption in the public sector: evidence from Vietnam

This research utilizes a structural equation modeling (SEM) technique to comprehensively examine the intricate interactions among various factors influencing corruption in Vietnam's public sector. The findings reveal that certain factors, including inadequate anti-corruption policies and enforcement, a lack of accountability and transparency in anti-corruption endeavors, and significant income disparities between public officials and anti-corruption measures, significantly and positively impact the cultural and social norms associated with anti-corruption. Additionally, insufficient cultural and social standards exert a notable and positive influence on the level of corruption in the public sector. The outcomes of this study provide valuable insights for developing effective policies and strategies that promote accountability, transparency, and good governance to combat corruption in Vietnam's public sector

Vibrational Study of the Hydrogen Adsorption on the Missing Row Platinum (110) Surface

The hydrogen vibration was investigated to analyze its affect on the hydrogen adsorption on the missing row platinum surface (H/Pt(110)-(1$\times$2) model) in the ultrahigh vacuum (UHV). The density functional theory (DFT) combined with the approximation oscillation of the hydrogen atom on the surface was used. When the hydrogen coverage ΘH on the surface is 100% ($\Theta$ = 1 ML), and taking into account the vibrational effect, the bond formed at the edge of the first layer (short bridge) is the most stable site. The vibrational effect on the adsorption model H/Pt(110)-(1$\times$2) is significant

On the causality relationship between demographic changes, economic growth and domestic savings in Vietnam

The study aims to investigate the short run and long run relationships between demographic factors (population growth and the age dependency ratio), economic growth (GDP per capita growth) and domestic savings in Vietnam for the period of 1986 to 2016 using the cointegration and Wald tests. The findings revealed that there is a cointegration relationship between domestic savings and demographic and economic variables, while Wald test shows a unique causality trend running from population growth to domestic savings in Vietnam. The policy implications from this study suggest that the Vietnam government should focus on boosting economic growth (GDP per capita growth) through mobilizing its resources, managing fertility level between urban and rural areas and population growth in relation with growth rate of the economy. Moreover, the Vietnam government should take advantage of the golden population structure and limit the effects of the dependency ratio through offering attractive beneficial programs for the elderly and provide opportunities to increase their productivity, and thus spur savings in Vietnam

IMPACT OF THE EVFTA AGREEMENT: A STUDY ON VIETNAM'S EXPORTED GOODS

Abstract The research aims to assess the quantitative impact of the Vietnam-European Union Free Trade Agreement (EVFTA) on Vietnam's export growth to the EU market. The study employs quantitative analysis using the SMART model with data on export turnover and scenarios of tariff reduction to 0% when EVFTA takes effect. Based on the export turnover data and necessary parameters, the analysis results show an increase in Vietnam's exports to the EU market when EVFTA becomes effective. As a result, the research proposes some implications to promote Vietnam's export activities to the EU in the future

Acetate wheat starch improving blood glucose response and bilan lipid on obesity dyslipidemia mice

Resistant starch is particularly concerned with beneficial effects in regulating blood glucose concentration and lipid metabolism, reducing the risk of diabetes and cardiovascular diseases. This study aimed to validate the effects of wheat starch acetate containing 32.1% resistant starch on postprandial blood glucose response and lipid profile on obesity, dyslipidemia Swiss mice induced by a high-fat diet. The result showed that there was a restriction on postprandial hyperglycemia and remained stable for 2 hours after meal efficiently comparing with the control group fed natural wheat starch. Simultaneously, when maintaining the dose of 5g/kg once or twice a day for 8 weeks, wheat starch acetate to be able to reduce body weight and blood glucose, triglyceride, cholesterol levels compared to the control group (p<0.05)

Ammonia oxidation capacity of bacillus bacteria in swine wastewater after biogas treatment

Nitrogen removal with biological methods plays a crucial role in wastewater treatment technology. The treatment begins with the oxidation of ammonia to nitrite to facilitate the subsequent nitrification and denitrification. Various strains of ammonia-oxidising bacteria have been reported. In this study, we use three Bacillus bacteria isolated from swine wastewater to oxidise ammonia. Different initial densities (103, 104, 105, and 106 CFU·mL–1) of each strain were examined. The results show that the combination of all the bacteria at a ratio of 1:1:1 and a density of 105 CFU·mL–1 exhibits the most effect. The findings contribute to the diversity of ammonia-oxidising bacterial species and pose a great potential for applying these strains in wastewater treatment

Nitrite metabolism of several bacterial strains isolated from abattoir and swine wastewater after biogas treatment

In nitrogen treatment with biological methods, nitrite metabolism is an intermediate process that facilitates other processes involving different bacteria strains. In this study, we isolated two nitrite-oxidising bacteria strains from abattoir wastewater and wastewater from biogas tanks of an industrial pig farm in Ha Tinh province. The bacteria strains grow, develop, and metabolise nitrite at pH 6–8 and 30–37 °C. The samples with the nitrite concentration up to 750 mg·L–1 were oxidised within four days of incubation, and the nitrite metabolism rate was proportional to the concentration of nitrite tested. Under severe conditions (salinity up to 3% NaCl, a low dissolved oxygen level of 0.1 mg·L–1), the two isolated bacterial strains exhibited their effective growth and nitrite metabolism capacity. The results enrich the database of nitrite-oxidising bacteria and are prospective in wastewater treatment
