The paper presents an overview of sociolinguistics and analyses its importance in the L2 development and second language learning (SLL). A number of sociolinguistic issues then are discussed to provide further explanations for the critical role of sociolinguistics in SLL through an analysis of empirical studies in this field.

In civil engineering, the study of embankment settlement on soft ground is a vital geotechnical task in order to maintain serviceability of the road embankment, pavement, and facilities. This paper presents a study on settlements of road embankment on soft ground using vertical drains, including prefabricated-vertical drain (PVD), sand drain (SD), and sand compaction pile (SCP) on a number of packages of Hanoi – Haiphong Expressway Construction Project.

The "determining modes" concept introduced by Foias and Prodi in 1967 say that if two solutions agree asymptotically in their P projection, then they are asymptotical in their entirety. In this paper, we consider the 2D g-Bénard problem in domains satisfying the Poincaré inequality with homogeneous Dirichlet boundary conditions.

The score function is used to compare intutionistic fuzzy numbers. In this paper, a novel score function of intuitionistic fuzzy sets (IFSs) is investigated. The novel score function was constructed by combining the polynomial and exponential functions working on the degree of membership and degree of non-membership of intuitionistic fuzzy sets.

This paper investigates the driving forces of decision making on correspondent banking relationships (CBRs), focusing on two decisions: Whether to establish a correspondent bank (CB) in a country, which we refer to as country selection, and then how many CBs are established in each country, which we label as number decision.

This paper develops a constant friction coefficient model that best represents a velocity-dependent friction model for predicting structural response of buildings isolated with concave friction bearings. To achieve this goal, the effect of friction model on structural response of three hypothetical isolated buildings with different number of stories subjected to different earthquake scenarios was numerically investigated.

This paper summarizes the basic principle of FEM and DEM, then reviews a number of possible direct coupling strategies between FEM and DEM together with potential applications in civil engineering. The second objective is to develop a model that combines these two above mentioned methods in a multi-scale approach.

The shear behavior of steel fiber reinforced concrete (SFRC) beams has been assessed in a large number of previous studies. However, the shear strength of corroded SFRC beams without shear reinforcement is still an unresolved topic. In this paper, the finite element models of non-corroded and corroded SFRC beams have been constructed and verified regarding load-displacement curves, crack patterns, and failure modes.

The purpose of this study is to examine if CSR practices have a correlation with companies’ performance of the twenty Vietnamese firms. Despite a large number of studies on CSR with the sole focus on emerging economies, this concept in the specific Vietnamese market has yet to receive apprehension and qualified research. Therefore, this paper provides a quantitative approach to study the relationship between CSR and financial performance of Vietnamese firms in three distinct sectors: banking, real estate and food manufacturing.

This paper describes an investigation of fluid flow through two tandem circular cylinders using Lattice-Boltzmann Method in direct numerical simulation. The diameter ratio of two circular cylinders, D1/D2 varies from 0.5 to 1.5, and spacing ratio (L/D2) varies from 1.5 to 10, whereas the Reynolds number of 100 is considered. The numerical model is well validated by comparing the results with those obtained in the literature.

This paper contributes to the literature on the internationalization process of new ICT companies, especially the ride-hailing developer firms. It analyzes the global expansion of UBER in the Asian market. UBER did an aggressive expansion using a standard business model in every market that they get into. The strategy was on scale economy rather than localization of services. The case analysis suggests that UBER was unsuccessful in its global expansion due to a number of factors especially t

In this paper "New provincial records of skinks (Squamata: Scincidae) from northwestern Vietnam", we report six new records of skinks from northwestern Vietnam: Eutropis macularius, Scincella devorator, S. monticola, S. ochracea, Sphenomorphus cryptotis and S. indicus. Our new findings increase the species number of skinks (Scincidae) to nine in Dien Bien Province and to 14 in Son La Province. We also provide additional natural history data of aforementioned species.

As more Koreans invested in Vietnam, the number of foreign students in Korea increased due to the perception that studying in Korea would be beneficial for employment within Vietnam. Also, the ratio of international students entering graduate school is increasing. In this study, the researches related to Vietnam were investigated, focusing on the articles and papers of journals searched through the Vietnam keyword of the National Assembly Library. We also have examined research trends through Big Data Analysis.
