Improving the quality of university library services to meet the requirements of basic educational quality accreditation

This paper examines the results of quality accreditation of library criteria retrieved from universities (according to the set of standards issued by the Ministry of Education and Training) from 2016 to the present. By studying the limitations of libraries, recommendations from external organizations for quality accreditation and identifying the causes, the authors propose solutions to improve the quality of university library services. Proposed solutions involve the library's initiative in understanding user needs and providing services that meet the needs of learners and stakeholders, carrying out good management of libraries and periodically surveying users to better the quality of library service

Students’ perceptions of using note-taking in consecutive interpreting assignments

Note-taking is critical in helping interpreters memorize detailed information both quickly and accurately. Therefore, the present study was conducted as a questionnaire survey at a university in the Mekong Delta of Vietnam to investigate how students, specifically student interpreters, perceive note-taking in consecutive interpreting assignments. In detail, this study explores the students’ perceptions of the benefits and the challenges of using note-taking in consecutive interpreting assignments. The participants in this study comprised 160 students majoring in English Interpretation and Translation. Furthermore, they have taken consecutive interpreting courses and experienced taking notes in consecutive interpreting tasks. The findings of this study indicated that most students had good perceptions about note-taking used in consecutive interpretation and perceived its benefits and challenges. Moreover, some pedagogical implications for both students and teachers are made. Specifically, the study suggests that students should frequently practice it to acquire good note-taking skills. Teachers should make effective lecture designs to help students improve their note-taking skills and consecutive interpreting performance

Universality in odd-even harmonic generation and application in terahertz waveform sampling

Odd-even harmonics emitted from a laser-target system imprint rich, subtle information characterizing the system's dynamical asymmetry, which is desirable to decipher. In this Letter, we discover a simple universal relation between the odd-even harmonics and the asymmetry of the THz-assisted laser-atomic system -- atoms in a fundamental mid-IR laser pulse combined with a THz laser. First, we demonstrate numerically and then analytically formulize the harmonic even-to-odd ratio as a function of the THz electric field, the source of the system's asymmetry. Notably, we suggest a scaling that makes the obtained rule universal, independent of the parameters of both the fundamental pulse and atomic target. This universality facilitates us to propose a general pump-probe scheme for THz waveform sampling from the even-to-odd ratio, measurable within a conventional compact setup

Survey on Vietnamese teachers’ perspectives and perceived support during COVID-19

The COVID-19 pandemic has caused unprecedented damage to the educational system worldwide. Besides the measurable economic impacts in the short-term and long-term, there is intangible destruction within educational institutions. In particular, teachers – the most critical intellectual resources of any schools – have to face various types of financial, physical, and mental struggles due to COVID-19. To capture the current context of more than one million Vietnamese teachers during COVID-19, we distributed an e- survey to more than 2,500 randomly selected teachers from two major teacher communities on Facebook from 6th to 11th April 2020. From over 373 responses, we excluded the observations which violated our cross-check questions and retained 294 observations for further analysis. This dataset includes: (i) Demographics of participants; (ii) Teachers' perspectives regarding the operation of teaching activities during the pandemic; (iii) Teachers' received support from their schools, government bodies, other stakeholders such as teacher unions, and parents' associations; and (iv) teachers' evaluation of school readiness toward digital transformation. Further, the dataset was supplemented with an additional question on the teachers' primary source of professional development activities during the pandemic

Effect of Molecular Charge Asymmetry on Even-to-odd Ratio of High-order Harmonic Generation

Recently, asymmetric molecules, such as HeH$_2^+$, CO, OCS, HCl, have been evolved much attention since its rich information in the high-order harmonic generation (HHG), whose ratio of adjacent even and odd harmonics characterizes the asymmetry of molecules. In this paper, we study the dependence of even-to-odd ratio on the asymmetric parameters, in particular, the nuclear-charge ratio, and the permanent dipole, by exploiting a simple but general model of asymmetric molecules $Z_1Z_2$ subjected to an intense laser pulse. The HHG is simulated by the numerical method of solving the time-dependent Schrödinger equation. We find out that this even-to-odd ratio strongly depends on the nuclear-charge ratio. In particular, the even-to-odd ratio reaches its maximum when the nuclear-charge ratio is about from 0.5 to 0.7. Besides, the dependence on the permanent dipole of the even-to-odd ratio has a non-trivial law. To explain, we calculate the analytical ratio of the transition dipole according to the emission of even and odd harmonics, and this ratio is well consistent with the even-to-odd ratio of the HHG
