The Factors Affecting Entrepreneurial Intention With Self Confidence as a Moderator - Based on Elderly People as an Example

Purpose: This study aims to determine the factors affecting the entrepreneurial intention of young people in Vietnam, thereby assessing the level of these influencing factors to propose solutions and entrepreneurship orientations effectively in the future.   Theoretical framework:  After synthesizing previous studies, the study has found some studies that mention the impact on the entrepreneurial intention of students and young people while finding a research gap that has not been studied on this issue among elderly people. Therefore, the authors proposed a research model with factors as follows: Family support, government policy, self-confidence, and capital, which affect entrepreneurial intention.   Design/methodology/approach: This study uses SPSS software to test the hypothesis by linear regression method and to test the research hypothesis with survey samples conducted in 5 months 1310 votes were collected, including 972 valid votes. The age of survey participants is between 45 and 65 years old..   Findings:  The results show that the capital factor does not affect the entrepreneurial intention while the entrepreneurial experience factor has the strongest impact on the start-up intention. Next, it is support from the government and support from family. Finally, it is self-confidence. That proves that capital is not an essential issue for elderly people because they have already accumulated capital before. Whereas, the experience factor refers to a long process of working. The longer they work, the more experienced they get, thereby increasing their ability to be confident and successful in doing business in their old age.   Research, Practical & Social implications:  The proposal of this study will be an important reference for start-ups and related government agencies. It aims to promote breakthrough business ideas and exploit the essence of experienced people who have retired. This object needs special attention to develop the country's economy sustainably.   Originality/value:  Identified a research gap from previous studies there are no studies into the object of elderly people. The research results have been through a methodical and professional data acquisition process in two forms, such as quantitative and qualitative methods, thereby proposing research models. The research results are to find out the difference with the previous topics. Also, it is proposed to be an important reference for agencies and organizations related to start-up activities in Vietnam

The Zn-finger transcription factor ZAT12 : a molecular link between iron deficinecy responses and oxidative stress

Plants grown under conditions where iron is poorly available induce a set of genes which enhance the efficiency of its uptake by the roots. A central regulator of this response in the model plant Arabidopsis (Arabidopsis thaliana) is the basic helix-loop-helix transcription factor FIT whose activity is tightly regulated. We identified the oxidative stress-responsive zinc finger transcription factor ZAT12 in an attempt to find a link between iron deficiency responses and oxidative stress. ZAT12, whose expression is upregulated by several stresses like oxidative, cold and heat stresses etc., contains an EAR motif and is thought to function as a repressor of gene expression. Using yeast-two-hybrid assay, we demonstrate that the EAR motif is necessary for the interaction between FIT and ZAT12. Expression of the FIT gene was upregulated in zat12 loss-of-function plants. In addition, these plants accumulated higher amount of iron compared to the wild type. We generated transgenic plants expressing ZAT12 protein fused to GFP driven by the ZAT12 upstream DNA sequence. GFP fluorescence was detected in Arabidopsis roots, where it could be observed in the nuclei. Abundance of this protein was elevated upon iron deficiency, H2O2 and MG132 treatment. We conclude that ZAT12 links iron deficiency and oxidative stress responses through direct interaction with and negative regulation of FIT.Wenn Pflanzen unter Bedingungen wachsen, bei denen Eisen nur gering verfügbar ist, induzieren sie ein Set von Genen, die die Effizienz der Eisenaufnahme durch die Wurzel steigern. Ein zentraler Regulator dieser Antwort in der Modellpflanze Ackerschmalwand (Arabidopsis thaliana) ist der basische Helix-Loop-Helix-Transkriptionsfaktor FIT, dessen Aktivität eng reguliert ist. Im Versuch, eine Verbindung zwischen den Antworten auf Eisenmangel und oxidativen Stress zu finden, haben wir den Zinkfinger-Transkriptionsfaktor ZAT12 identifiziert, dessen Expression durch verschiedene Stresse wie oxidativem Stress, Kälte- oder Hitzestress hochreguliert wird. ZAT12 enthält ein EAR-Motiv und wirkt vermutlich als Repressor der Genexpression. In einem Yeast-Two-Hybrid-Assay konnten wir zeigen, dass das EAR-Motiv für die Interaktion zwischen FIT und ZAT12 erforderlich ist. Die Expression des FIT-Gens wurde in zat12-Loss-of-Function-Pflanzen hochreguliert. Außerdem akkumulierten diese Pflanzen mehr Eisen als der Wildtyp. Wir haben transgene Pflanzen generiert, die unter der Kontrolle der ZAT12-Promotors ein ZAT12- GFP-Fusionsprotein exprimieren. GFP-Fluoreszenz wurde in den Zellkernen von Arabidopsis-Wurzeln detektiert. Die Menge dieses Proteins war sowohl unter Eisenmangel als auch unter H2O2- und MG132-Behandlung erhöht. Daraus folgern wir, dass ZAT12 Antworten auf Eisenmangel und oxidativen Stress durch direkte Interaktion mit FIT und dessen negative Regulation verbindet

The Impacts of Foreign Language Anxiety on Students in English-Medium Instruction Classes in the Central Region Universities, Vietnam

This study investigates the anxiety frequency of students in English-medium instruction classes and its relationship with gender and English performance. The questionnaire was administered to 300 students in three universities in Central Vietnam. The follow-up interviews and classroom observations were conducted to obtain more insights into the research problems. The results revealed that the EMI students had moderate levels of anxiety. The most provoking causes of students’ anxiety were worries about making mistakes, inconfidence during speaking tasks and fears of negative judgment from peers and teachers. The analyses of the variables related to foreign language anxiety revealed a significant negative correlation between students’ foreign language anxiety levels and their English competence. No statistically significant relationship was found between male and female students. The study provides several pedagogical insights for curriculum designers, educators and teachers to improve the quality of English-medium instruction courses in the Vietnamese context

A research on the performance of down-flow hanging sponge (DHS) reactor treating domestic wastewater

The aim of this study was to evaluate the performance of a down-flow hanging sponge (DHS) system in treating domestic wastewater. A pilot-scale of DHS system with a capacity of 60 L was designed and fabricated from polyvinyl chloride (PVC). The dimensions of DHS system are 1.5 m in height and square surface with 0.2 m in width, consists of three identical segments connected vertically in series. Each segment was filled by polyurethane sphere containing sponge. The total area of sponge and polyurethane sphere was 3,300 m2 m-3, density at 150 kg m-3, void ratio at 90%. DHS system was operated at ambient temperature within 82 days and stepwise increased of organic f rate from 0.5 to 1 and 1.5 kg COD m-3 d-1. The results showed that, this system performed well throughout the operational period and achieve the maximum removal of COD, BOD5, NH4+-N, and TN as 80%, 83%, 65% and 60%. The effluent of wastewater from DHS system achieved the requirement for National technical regulation on domestic wastewater of Vietnam type B QCVN 14:2008/BTNMT. In conclusion, the performance of DHS system indicated a high potential for application in removing organic matter and converting nitrogen ammonia to nitrogen nitrate, however it did not perform well for the removal of total nitrogen, it is necessary to study further by providing an anoxic zone in the system to enhance the treatment of nutrient in wastewater

On the central symmetry of the circumstellar envelope of RS Cnc

We present a phenomenological study of CO(1-0) and CO(2-1) emission from the circumstellar envelope (CSE) of the Asymptotic Giant Branch (AGB) star RS\,Cnc. It reveals departures from central symmetry that turn out to be efficient tools for the exploration of some of the CSE properties. We use a wind model including a bipolar flow with a typical wind velocity of $\sim$8 km\,s$^{-1}$ decreasing to $\sim$2 km\,s$^{-1}$ near the equator to describe Doppler velocity spectral maps obtained by merging data collected at the IRAM Plateau de Bure Interferometer and Pico Veleta single dish radio telescope. Parameters describing the wind morphology and kinematics are obtained, together with the radial dependence of the gas temperature in the domain of the circumstellar envelope probed by the CO observations. Significant north-south central asymmetries are revealed by the analysis, which we quantify using a simple phenomenological description. The origin of such asymmetries is unclear.Comment: accepted for publication in Research in Astronomy and Astrophysics (RAA

AN INVESTIGATION INTO THE USE OF COLLOCATIONS IN ACADEMIC ESSAYS OF ENGLISH-MAJORED STUDENTS OF THE HIGH-QUALITY PROGRAM AT CAN THO UNIVERSITY, VIETNAM

One of the main goals of language learners is to master all four skills of listening, speaking, reading and writing when it comes to their acquisition of the target language. However, during the process of learning English, learners inevitably face a variety of challenges related to their writing including grammatical errors, word choice, organization, idea development, and most importantly their difficulties in using collocations (Duong & Nguyen, 2021). Therefore, this study has been conducted to investigate the students’ use of English collocations in their academic essays associated with their difficulties so that appropriate pedagogical approaches and practices would be taken into consideration in order to help students improve their English collocational competences in academic writing. This descriptive study was carried out with 103 English-majored students of the High-quality program of the School of Foreign Languages at Can Tho University, Vietnam. A 5-point Likert scale survey with 18 questionnaire items was employed to examine the frequency of students' exposure to as well as their usage of English collocations, and their difficulties in using English collocations. The results of this study have shown that the most commonly used collocations in the students’ academic essays were ‘verb + noun’, and ‘adjective + noun’ lexical collocations. Additionally, the research outcomes have revealed that the types of English collocations that the students were more likely to make the most mistakes belonged to ‘verb + adverb’, and ‘adjective + noun’ lexical collocations.  Article visualizations
