Current Issues

The present paper was to discuss how the use of the progressive forms with stative verbs has changed in present-day English and discuss what the teachers should do to deal with this issue in English grammar teaching. The discussion of the paper was based on theoretical framework of progressive aspect and stative verbs. Data collected from three corpus-informed grammar textbooks show that there has been being a change in grammatical usage, specifically in the use of the progressive form with stative verbs. In particular, traditional views support the limitation of the use of the progressive form with stative verbs, while present-day English ones prove that many stative verbs can be used in progressive form. Through the discussion, the writer of the present paper finally suggested two pedagogical implications for teaching English progressive aspect.

In the paper, we investigate the structure and electronic properties of the pristine germanene nanoribbon and four adsorption configurations of 1F and 2F on the substrate of germanene nanoribbon. We obtained the parameters of the most stable structures of pristine germanene nanoribbon and four adsorption configurations. The band structure and the density of state and the part density of state for each element were also obtained. Findings show the adsorption configuration of 1F-GeNR.bridge has no band structure, while other configurations are semimetals with band gap from 0.175eV to 0.67eV; both four adsorption configurations are chemisorption and non-magnetic. The charge distribution of all configurations also was investigated; it showed that there is a charge shift from Ge atoms towards F atoms due to their electronegativity difference.
Oral history is both a method of gathering information and an important source of historical data in social history and public history. The narratives of individuals are not only exploited to find historical facts or “additional” details to a grand narrative but uncover the meaning of individuals’ stories for a broader social context. That shift has made oral history increasingly an interdisciplinary research method. However, compared with the popularity of oral history in international academic disciplines, the application of this research method restricts in Vietnam. This article presents the possibilities and prospects of oral history through different research topics/fields in history, at the same time, specify the causes of obstacles to the legitimization of oral history in Vietnam.

ABSTRACT With the ever-increasing development of technology, online teaching is more readily accepted as a viable component in teaching and learning, and blended learning, the combining of online and face-to-face learning, is becoming commonplace in many higher education institutions. Definitely, challenges cannot be denied; however, it has been suggested and deployed globally including Vietnam. To some extent, both teachers and students present their positive points of view on this learning approach. However, there are a huge number of students expressing their lack of understanding the blended learning, which negatively affects their attitudes towards deployment of this learning approach as well as particular reference to motivation and interest. This paper is to assess the English majors’ perceptions on blended learning environment at tertiary level, which especially affects their learning the writing skills. Results of the study are absolutely helpful for the author to understand the students’ perceptions of the effects on the blended learning; then, she can give some suggestions to enhance the learning of writing skills in the light of blended learning. Key word: Blended learning, academic writing, perception
This paper is devoted to study a fractional equation involving Caputo-Katugampola derivative with nonlocal initial condition. Unlike previous papers, in this paper, the source function of problem is assumed having a singularity. We propose some reasonable conditions such that the problem has at least one mild solution or has a unique mild solution. The desired results are proved by using the Banach, Leray-Schauder and Krasnoselskii fixed point theorems. Some examples are given to confirm our theoretical findings.

Abstract: The article is based on data from the research program "Greater Mekong Subregion Flood and Drought Risk Management and Mitigation Project (ADB-GMS1)" jointly implemented by the Asian Development Bank (ADB) and the Ministry of Agriculture and Rural Development, and the Vietnam Institute of Water Resourches Research in Tien Giang and Dong Thap province. The results show that, in recent years, due to the increasingly severe global climate change, the intensity of various types of natural disasters occurs more frequently, irregularly and with greater intensity. This has greatly affected the production, daily life and properties of the people in the vulnerable areas. To reduce the impact of various types of disasters on people living in vulnerable areas, it is necessary to combine two types of solutions in disaster prevention, namely construction solutions and non- construction solutions. In which, non-construction solutions play a very important role, namely, people living in communities are considered as the main actors in preventing and mitigating disaster risks occurring in the community.

Performance-related pay (PRP) is an integral part of Reward Management (RM) and is considered to have beneficial effects on organisational performance and employee motivation. Drawing on 14 case studies, this paper examines the Reward Management practices of local and multinational companies in Australia with specific consideration to PRP within the debate over the applicability of the transfer of the Human Resource Management (HRM) practices between nations through subsidiary-parent company relationships. After reviewing the relevant literature(s), the study concentrates on finding whether multinational corporations (MNC) in Australia pursue similar or different RM practices compared to their domestically owned Australian counterparts with special reference to PRP. It also investigates whether there are national variations between multinational companies in terms of the nature and character of their practices. The findings reveal country of origin differences in the way PRP practices are applied in subsidiaries of foreign-owned companies in Australia and local Australian firms. The case studies are used to examine and explain the practices.
Chau Pha Lake is one of the large reservoirs providing water for domestic, irrigation and production of people in Phu My town, Ba Ria Vung Tau province. This study was conducted to analyze the parameters of pH, temperature, DO, BOD5, COD, N-NH4+, P-PO43-, TSS, turbidity, total Coliform on 16 samples in 2020 and the water quality index calculation WQI.
