No unbounded arbitrage, weak no market arbitrage and no arbitrage price system conditions: The circular results.

Page and Wooders (1996) prove that the no-unbounded-arbitrage (NUBA) condition introduced by Page (1987) is equivalent to the existence of a no arbitrage price (NAPS) when no agent has non-null useless vectors. Al- louch, Le Van and Page (2002) show that their generalized NAPS condition is actually equivalent to the weak-no-market-arbitrage (WNMA) condition introduced by Hart (1974). They mention that this result implies the one given by Page andWooders (1996). In this note, we show that these results are actually circular.Arbitrage, Equilibrium, Recession cone.

An updated list of monogenoidea from marine fishes of Vietnam

In this paper, we updated the list of monogenean species from marine fishes of Vietnam. Taxonomic position of monogenean species were arranged according to the current classification system. A total of 220 monogenean species from 152 marine fish species were listed. Distribution, hosts and references of each species were given. In addition, amendations of taxonomic status of taxa were also updated. 

The Relationship Between the Human Capital and Economic Growth: A Case of Vietnam

Human capital are not only the engine of economic growth but also increase the global competitiveness for countries. Improving labor quality helps countries improve long-term economic efficiency. This article uses annual data in the period 1990 - 2017 in Vietnam, which attempts to explore the relationship between total capital formation, the labor quantity, education levels and life expectancy with economic growth. By using OLS regression, the analysis results shown that the gross capital formation, the labor quantity, education levels and life expectancy are positive and have a significant impact on GDP in Vietnam. Furthermore, the Granger causality test indicates that there is a two-way causal relationship between labor and economic growth (GDP) in Vietnam.

Industrial characteristics, the size of countries, and the extensive margin of trade

This dissertation consists of three chapters exploring some issues in International Trade. Chapter 1 explains how home-market effects change across industries in a model of monopolistic competition with heterogeneous firms. The home-market effect hypothesis (Krugman (1980)) states that a large country has more firms (or products) in an increasing return sector than does a small country. However, the large country\u27s share of firms (or products) across industries in an increasing return to scale may vary with industry characteristics. This chapter builds a model of monopolistic competition with heterogeneous firms to investigate which industry characteristics have effects on that change. The model includes two countries with many industries of differentiated products and one industry of homogeneous goods. The model predicts that industries with low trade costs, high fixed-domestic costs, low fixed-export costs, and high productivity dispersion will tend to concentrate in a large country. Chapter 2 demonstrates empirical evidence to support the first chapter\u27s predictions. As the characteristics of an industry are assumed to be homogeneous across countries, I use a sample of 28 developed countries. This ensures that industry characteristics are similar across countries. In addition, I use the four-digit ISIC industrial classification to categorize countries\u27 industries and use the method of Hummels and Klenow (2002) to measure the relative number of products (or firms) between two countries. The empirical evidence is found to support the predictions from the theoretical model. Chapter 3 examines how the extensive and intensive margins of trade in developing countries respond to changes in trade barriers through import and export demand functions. The study finds that trade liberalization has a significant impact on both the extensive and intensive margins of trade in developing countries. However, only the intensive margin of trade responds significantly to the yearly change of import and export duties, while the extensive margin responds insignificantly to this. These results are consistent with the theoretical predictions of Ruhl (2008). The method of Hummels and Klenow (2002) is used to measure the extensive and intensive margins and the dynamic-panel regression method is used to estimate models in this paper

A STUDY OF THE SERVANT LEADERSHIP OF DOMINICAN SEMINARIANS AT PARISHES IN VIETNAM

This study was on the servant leadership of Dominican seminarians at parishes in Vietnam. The objectives of this study were (1) to examine the current servant leadership of seminarians serving at the parishes in Vietnam (2) to determine the relationship between seminarians’ servant leadership and their demographic factors including age, educational attainment and years of serving experience.The research method which was used for this study was a quantitative approach. A Likert scale questionnaire which based on Barbuto and Wheeler’s (2006) theory was used to determine servant leadership qualities of 265 seminarians at the Dominican Seminary in Vietnam. The data from questionnaire was analyzed by using descriptive statistics and Pearson Production Moment Correlation Coefficients test.This study showed that (1) the Dominican Seminarians fairly practiced servant leadership when serving at parishes in Vietnam; (2) there was no significant relationship between seminarian servant leadership qualities and their demographic elements including age and educational attainment. The findings from this study could be useful for the administrators of the Seminary in Vietnam to further improve their training quality for current and new seminarians in order to achieve the ideal mission instilling a greater sense of servant leadership in them. In general, these findings could also provide a fresh impetus for all seminarians to strengthen their faith and perform their duty effectively

How scientific research changes the Vietnamese higher education landscape: Evidence from social sciences and humanities between 2008 and 2019

Background: In the context of globalization, Vietnamese universities, whose primary function is teaching, there is a need to improve research performance. Methods: Based on SSHPA data, an exclusive database of Vietnamese social sciences and humanities researchers’ productivity, between 2008 and 2019 period, this study analyzes the research output of Vietnamese universities in the field of social sciences and humanities. Results: Vietnamese universities have been steadily producing a high volume of publications in the 2008-2019 period, with a peak of 598 articles in 2019. Moreover, many private universities and institutions are also joining the publication race, pushing competitiveness in the country. Conclusions: Solutions to improve both quantity and quality of Vietnamese universities’ research practice in the context of the industrial revolution 4.0 could be applying international criteria in Vietnamese higher education, developing scientific and critical thinking for general and STEM education, and promoting science communication
