Managerial Recommendations Improving the Competitive Capability of Firms Based on Total Quality Management during Covid-19 Pandemic

In 2021, the COVID-19 epidemic affected many aspects of the provinces' socio-economic fields, especially deeply affecting businesses at enterprises. The task of ensuring social security continues with the management agencies, who need appropriate solutions and support policies to encourage and help enterprises return to production and trade after the quarantine society quickly. The basis for management theory has contributed to improving the competitive capability based on improving Total Quality Management (TQM), such as the "just in time" system. TQM aims to enhance the quality of products and satisfy customers to the best extent possible. The distinguishing feature of TQM from previous quality management methods is that it provides a comprehensive system for managing and improving all aspects related to quality and involves the participation of the public, every department, and every individual to achieve the set quality goals. The article's novelty identifies factors influencing total quality management and competitive capability of firms in Vietnam with one percent significance. Methods: The authors surveyed 650 managers at many enterprises in Vietnam. And the authors used a convenient sampling method. SPSS tools processed 589 samples to measure Cronbach's alpha, exploratory factor analysis (EFA), confirmation factor analysis (CFA), and test structural equation modeling (SEM). The authors proposed several recommendations to enhance the total quality management and competitive capability of firms. Doi: 10.28991/ESJ-2022-06-03-010 Full Text: PD

Comparing Traditional Body Mass Index and Joslin Diabetes Center’s Asian Body Mass Index in Predicting Self-Report Type 2 Diabetes.

This study examined the predictability of traditional Body Mass Index standards and the Joslin Diabetes Center’s recommended BMI standards for Asian Americans. A sample of 2973 adult Asian Americans aged 45 and older from the 2009 California Health Interview Survey (CHIS) was used. This sample consists of 12.25% of respondents with type 2 diabetes and 87.75% that had neither type 2 or any types of diabetes. Logistic regression was used to estimate the predictability of two the BMI standards and to test for the interaction effect of BMI standards and sex in predicting type 2 diabetes. The results revealed that both traditional and Joslin Diabetes Center’s recommended standards had similar predictability of types 2 diabetes. Both BMI standards of overweight and obesity had a greater association with type 2 diabetes for men than for women. That is, given a similar level of BMI, men tend to report a greater prevalence of type 2 diabetes than women. These findings support caution in changing BMI cut-offs for Asian Americans, and highlight the potential limitations of using BMI as a measure of risk for diabetes in this population

EFL Vietnamese Teachers’ Perception Toward Critical Thinking in the Classroom

The 21st academic curriculum worldwide has emphasized Critical Thinking as one of the paramount thinking skills. However, the fact that whether EFL teachers- as direct guides in the classroom- have thoroughly grasped the concept, have been exposed to the concept or equipped with adequate methods and approaches to teach critical thinking in daily lessons remains questionable. This paper aims to present the Vietnamese EFL teachers’ perceptions of critical thinking and provide an overview of their current practices of critical thinking skills. The paper emphasized the extent of understanding of critical thinking that Vietnamese EFL teachers show in comparison with definitions in the literature, and how they apply what they understand in the EFL classroom. Participants of the study are 5 teachers who have teaching experience of more than 3 years, and the researchers collected data through in-depth interviews. The findings revealed a lack of information and training from the participants as well as some challenges in practicing the skills due to time-constraints or inadequate general knowledge and limited language level of students. This paper gives EFL managers and practitioners’ assessment criteria for whether to include or exclude critical thinking in their classes and sheds light on how Vietnamese EFL teachers can structure their lessons to critical thinking in the classroom

Revisiting conventional noncovalent interactions towards a complete understanding: from tetrel to pnicogen, chalcogen, and halogen bond

Typical noncovalent interactions, including tetrel (TtB), pnicogen (PniB), chalcogen (ChalB), and halogen bonds (HalB), were systematically re-investigated by modeling the N⋯Z interactions (Z = Si, P, S, Cl) between NH$_3$ – as a nucleophilic, and SiF$_4$, PF$_3$, SF$_2$, and ClF – as electrophilic components, employing highly reliable ab initio methods. The characteristics of N⋯Z interactions when Z goes from Si to Cl, were examined through their changes in stability, vibrational spectroscopy, electron density, and natural orbital analyses. The binding energies of these complexes at CCSD(T)/CBS indicate that NH$_3$ tends to hold tightly most with ClF (−34.7 kJ mol$^{−1}$) and SiF$_4$ (−23.7 kJ mol$^{−1}$) to form N⋯Cl HalB and N⋯Si TtB, respectively. Remarkably, the interaction energies obtained from various approaches imply that the strength of these noncovalent interactions follows the order: N⋯Si TtB > N⋯Cl HalB > N⋯S ChalB > N⋯P PniB, that differs the order of their corresponding complex stability. The conventional N⋯Z noncovalent interactions are characterized by the local vibrational frequencies of 351, 126, 167, and 261 cm$^{−1}$ for TtB, PniB, ChalB, and HalB, respectively. The SAPT2+(3)dMP2 calculations demonstrate that the primary force controlling their strength retains the electrostatic term. Accompanied by the stronger strength of N⋯Si TtB and N⋯Cl HalB, the AIM and NBO results state that they are partly covalent in nature with amounts of 18.57% and 27.53%, respectively. Among various analysis approaches, the force constant of the local N⋯Z stretching vibration is shown to be most accurate in describing the noncovalent interactions
