Does Corporate Tax Avoidance Influence Firm Leverage of Vietnamese Listed Companies?  [PDF]
Hoang Thi Mai Khanh, Nguyen Vinh Khuong
Theoretical Economics Letters (TEL) , 2019, DOI: 10.4236/tel.2019.94069
Abstract: Corporate tax avoidance is defined by reducing taxes for any particular purpose, extending from the gracious remission of taxes expense arising from inconsistent customs for financial statements. In this paper, we examine the association between corporate tax avoidance and firm leverage. The trade-off theory is significant for explaining the relationship between tax avoidance behaviour and firm leverage. Consequently, the company directs to allow tax avoidance behaviour and accept the company’s leverage at a higher level than usual. The consequences commence to transaction costs, financial risks when viewing at company health from financial statements, but will maintain the company achieves the expected tax rates. We utilize STATA to test GMM on a sample of Vietnam listed firms data over the period 2010-2016. The sample data of 125 companies in the period from 2010 to 2016, all 875 observations were used for the analysis. The results show that there is a significant positive relationship between corporate tax avoidance on firm leverage in Vietnam. The research is essential to the regulator in controlling tax costs for companies, for investors in analyzing a corporate financial situation.

To estimate the genetic relationship of Vietnamese pigs in Central Highlands, we compared cytochrome b sequences of Vietnamese wild boars and Vietnamese domestic pigs with other Asian and European wild boars. The results showed that there were two wild boar populations locating in Vietnam Central Highlands including wild boars of group I and wild boars of group II. The Vietnamese wild boars of group II and domestic pigs were genetically close to Asian A1 and Asian A2 wild boar groups, whereas the Vietnamese wild boars of group I were genetically distinct from Asian A1, Asian A2 wild boar groups. The phylogenetic tree demonstrated that the Vietnamese wild boars of group I were clustered in one clade which was distinct from Asian wild boars and Europe wild boars. In addition, the Vietnamese wild boars of group I were estimated to have diverged from European wild boars at 421500 YBP, indicating that Vietnamese wild boar of group I could be isolated from other Asian wild boars. The single nucleotide polymorphism analysis showed that three Asian haplotypes were contributed in Vietnamese wild boars including A3 (TATG) haplotype in Vietnamese wild boar of group I and A1 (CATA) haplotype and A2 (CATG) haplotype in Vietnamese wild boars of group II. The A1 haplotype and A2 haplotype were also distributed in Vietnamese domestic pigs. Thus, there is a high possibility that Vietnam Central Highlands is a principal source for research on genetic diversity in Asian wild boar and domestic pig populations.

International Journal of Business and Management , 2012, DOI: 10.5539/ijbm.v8n2p29
Abstract: Following the storm of melamine in milk and lower protein milk index than the published standard, consumers are more and more cautious when they choose powdered milk for their children. More especially, the Vietnamese prefer to buy imported powdered milk rather than domestic powdered milk. Accordingly, this research is conducted to investigate which factors influence consumer-buying behavior toward imported milk powdered in Ho Chi Minh City through a quantitative survey of 110 consumers. Through multiple regression analysis, the findings indicate that product brand, advertisement, and country of origin are significant predictors of consumer-buying behaviors towards imported powdered milk. Sponsorship turned out to be insignificant factor in predicting the dependent variable. Among demographic characteristics only income was found to affect the consumer-buying behavior.

Abstract: The factors that govern the development of tuberculosis disease are incompletely understood. We hypothesized that some strains of Mycobacterium tuberculosis (M. tuberculosis) are more capable of causing disseminated disease than others and may be associated with polymorphisms in host genes responsible for the innate immune response to infection. We compared the host and bacterial genotype in 187 Vietnamese adults with tuberculous meningitis (TBM) and 237 Vietnamese adults with uncomplicated pulmonary tuberculosis. The host genotype of tuberculosis cases was also compared with the genotype of 392 cord blood controls from the same population. Isolates of M. tuberculosis were genotyped by large sequence polymorphisms. The hosts were defined by polymorphisms in genes encoding Toll-interleukin 1 receptor domain containing adaptor protein (TIRAP) and Toll-like receptor-2 (TLR-2). We found a significant protective association between the Euro-American lineage of M. tuberculosis and pulmonary rather than meningeal tuberculosis (Odds ratio (OR) for causing TBM 0.395, 95% confidence intervals (C.I.) 0.193–0.806, P = 0.009), suggesting these strains are less capable of extra-pulmonary dissemination than others in the study population. We also found that individuals with the C allele of TLR-2 T597C allele were more likely to have tuberculosis caused by the East-Asian/Beijing genotype (OR = 1.57 [95% C.I. 1.15–2.15]) than other individuals. The study provides evidence that M. tuberculosis genotype influences clinical disease phenotype and demonstrates, for the first time, a significant interaction between host and bacterial genotypes and the development of tuberculosis.

International Journal of Clinical Medicine (IJCM) , 2019, DOI: 10.4236/ijcm.2019.101003
Abstract: Objectives: The study aimed to describe the quality of sleep and explore factors especially Sleep Hygiene Practices associated with sleep quality among pregnant women. Study design: This is a cross-sectional study. Methods: 119 healthy pregnant women in two central hospitals in Vietnam were participated in this study. The Pittsburgh Sleep Quality Index (PSQI) was employed to evaluate sleep quality and the Modified Sleep Hygiene Practices was used to describe sleeping practices among pregnant women. Results: The results showed that while 58.8% pregnant women had quite good sleep quality, 41.2% of pregnant women had mild to moderate quality sleep disturbance. The quality of sleep was better in second trimester, but then getting worst in the third trimester. Multipara experienced worse sleep quality than nullipara. Poor sleep quality had a positive correlation with unhealthy Sleep Hygiene Practices including using an uncomfortable bed (p < 0.05), going to bed with variable bedtime (p < 0.01), watching TV or making call in bed other than sleep (p < 0.05), going to sleep without sleep sensation (p < 0.001) and staying in bed even though it was difficult to fall asleep (p < 0.001). Conclusion: Pregnant women should be taken care of on sleep quality, especially in the first and third trimester as they experience more change in hormone and physiology. Sleep Hygiene Practices should be emphasized in health education for pregnant women.

Open Journal of Social Sciences (JSS) , 2017, DOI: 10.4236/jss.2017.510026
This study aims to examine the death attitudes and perception about the death of the elderly in Vietnam in the current period. Using the scale based on the research work of Wong and his colleagues (1994) and concepts of Buddhism, the study was performed on 959 elderly people in three areas: The Nord, the Centre and the South of the country. Results of data analysis show that only a part of the studied believe in afterlife. They tend to believe that their death is caused by pain, sadness and missing dear people instead of the supernatural that force them to die. Concerning death attitudes, we note that the majority of the studied will make actions expressing their willingness to accept death. Age, education, gender and life arrangement affect death perception as well as death attitudes in which we also note the difference by self-reported health and satisfaction of material life.

Abstract: We have previously developed and validated a prognostic model to predict the risk for unfavorable outcome in Dutch adults with bacterial meningitis. The aim of the current study was to validate this model in adults with bacterial meningitis from two developing countries, Vietnam and Malawi. Demographic and clinical characteristics of Vietnamese (n = 426), Malawian patients (n = 465) differed substantially from those of Dutch patients (n = 696). The Dutch model underestimated the risk of poor outcome in both Malawi and Vietnam. The discrimination of the original model (c-statistic [c] 0.84; 95% confidence interval 0.81 to 0.86) fell considerably when re-estimated in the Vietnam cohort (c = 0.70) or in the Malawian cohort (c = 0.68). Our validation study shows that new prognostic models have to be developed for these countries in a sufficiently large series of unselected patients.

Abstract: Background The bacterial genus Shigella is the leading cause of dysentery. There have been significant increases in the proportion of Shigella isolated that demonstrate resistance to nalidixic acid. While nalidixic acid is no longer considered as a therapeutic agent for shigellosis, the fluoroquinolone ciprofloxacin is the current recommendation of the World Health Organization. Resistance to nalidixic acid is a marker of reduced susceptibility to older generation fluoroquinolones, such as ciprofloxacin. We aimed to assess the efficacy of gatifloxacin versus ciprofloxacin in the treatment of uncomplicated shigellosis in children. Methodology/Principal Findings We conducted a randomized, open-label, controlled trial with two parallel arms at two hospitals in southern Vietnam. The study was designed as a superiority trial and children with dysentery meeting the inclusion criteria were invited to participate. Participants received either gatifloxacin (10 mg/kg/day) in a single daily dose for 3 days or ciprofloxacin (30 mg/kg/day) in two divided doses for 3 days. The primary outcome measure was treatment failure; secondary outcome measures were time to the cessation of individual symptoms. Four hundred and ninety four patients were randomized to receive either gatifloxacin (n = 249) or ciprofloxacin (n = 245), of which 107 had a positive Shigella stool culture. We could not demonstrate superiority of gatifloxacin and observed similar clinical failure rate in both groups (gatifloxacin; 12.0% and ciprofloxacin; 11.0%, p = 0.72). The median (inter-quartile range) time from illness onset to cessation of all symptoms was 95 (66–126) hours for gatifloxacin recipients and 93 (68–120) hours for the ciprofloxacin recipients (Hazard Ratio [95%CI] = 0.98 [0.82–1.17], p = 0.83). Conclusions We conclude that in Vietnam, where nalidixic acid resistant Shigellae are highly prevalent, ciprofloxacin and gatifloxacin are similarly effective for the treatment of acute shigellosis.

Abstract: Background Optimising the fluid resuscitation of patients with severe malaria is a simple and potentially cost-effective intervention. Current WHO guidelines recommend central venous pressure (CVP) guided, crystalloid based, resuscitation in adults. Methods Prospectively collected haemodynamic data from intervention trials in Vietnamese adults with severe malaria were analysed retrospectively to assess the responses to fluid resuscitation. Results 43 patients were studied of whom 24 received a fluid load. The fluid load resulted in an increase in cardiac index (mean increase: 0.75 L/min/m2 (95% Confidence interval (CI): 0.41 to 1.1)), but no significant change in acid-base status post resuscitation (mean increase base deficit 0.6 mmol/L (95% CI: ?0.1 to 1.3). The CVP and PAoP (pulmonary artery occlusion pressure) were highly inter-correlated (rs = 0.7, p<0.0001), but neither were correlated with acid-base status (arterial pH, serum bicarbonate, base deficit) or respiratory status (PaO2/FiO2 ratio). There was no correlation between the oxygen delivery (DO2) and base deficit at the 63 time-points where they were assessed simultaneously (rs = ?0.09, p = 0.46). Conclusions In adults with severe falciparum malaria there was no observed improvement in patient outcomes or acid-base status with fluid loading. Neither CVP nor PAoP correlated with markers of end-organ perfusion or respiratory status, suggesting these measures are poor predictors of their fluid resuscitation needs.

Abstract: Background Central nervous system (CNS) infections are important diseases in both children and adults worldwide. The spectrum of infections is broad, encompassing bacterial/aseptic meningitis and encephalitis. Viruses are regarded as the most common causes of encephalitis and aseptic meningitis. Better understanding of the viral causes of the diseases is of public health importance, in order to better inform immunization policy, and may influence clinical management. Methodology/Principal Findings Study was conducted at the Hospital for Tropical Diseases in Ho Chi Minh City, a primary, secondary, and tertiary referral hospital for all southern provinces of Vietnam. Between December 1996 and May 2008, patients with CNS infections of presumed viral origin were enrolled. Laboratory diagnostics consisted of molecular and serological tests targeted at 14 meningitis/encephalitis-associated viruses. Of 291 enrolled patients, fatal outcome and neurological sequelae were recorded in 10% (28/291) and 27% (78/291), respectively. Mortality was especially high (9/19, 47%) amongst those with confirmed herpes simplex encephalitis which is attributed to the limited availability of intravenous acyclovir/valacyclovir. Japanese encephalitis virus, dengue virus, herpes simplex virus, and enteroviruses were the most common viruses detected, responsible for 36 (12%), 19 (6.5%), 19 (6.5%) and 8 (2.7%) respectively, followed by rubella virus (6, 2%), varicella zoster virus (5, 1.7%), mumps virus (2, 0.7%), cytomegalovirus (1, 0.3%), and rabies virus (1, 0.3%). Conclusions/Significance Viral infections of the CNS in adults in Vietnam are associated with high morbidity and mortality. Despite extensive laboratory testing, 68% of the patients remain undiagnosed. Together with our previous reports, the data confirm that Japanese encephalitis virus, dengue virus, herpes simplex virus, and enteroviruses are the leading identified causes of CNS viral infections in Vietnam, suggest that the majority of morbidity/mortality amongst patients with a confirmed/probable diagnosis is preventable by adequate vaccination/treatment, and are therefore of public health significance.
