The method of harvesting latex by slicing a groove into the bark of the tree mimics a mechanical wounding. In addition, rubber trees could be frequently exposed to pest and pathogen attacks through the scraped bark region. Terpenoids are a group of specialised compounds that play an important role in plant-environment interactions, especially in plant response to stress factors. The diversity of terpenoids is mainly determined by enzymes of the terpene synthase (TPS) family. Screening the RNA-seq data of H. brasiliensis revealed the presence of many putative TPS genes expressed in the bark tissues of rubber trees; however, their function has not been studied. This paper presents the identification of a TPS gene transcript variant (designated as HbTPS6L-X1) from the bark tissues of H. brasiliensis RRIV 209. Through the analysis of the phylogenetic tree, the presence of conserved motifs, and the signal peptide sequence region of the protein, as well as structural homology to known sesquiterpene synthases from other plants, HbTPS6L-X1 was predicted to belong to the TPS-a subfamily, be localised in the cytoplasm and catalyse the conversion of farnesyl diphosphate (FPP) to sesquiterpenes. These in silico functional characteristics are the basis for designing experiments to confirm the in planta biological function of HbTPS6L-X1 protein.","PeriodicalId":18650,"journal":{"name":"Ministry of Science and Technology, Vietnam","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139159715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various statistical techniques were employed to analyse the data, including the Cronbach’s Alpha test, exploratory factor analysis (EFA), and linear regression analysis. The findings reveal that the entrepreneurial intention of these graduates is positively influenced by a multitude of factors, such as behaviour control, subjective norms, attitude towards entrepreneurship, and perceived desirability, while being negatively impacted by the propensity to act. The study’s primary contribution is the provision of an updated and cohesive framework that enhances understanding of the entrepreneurial intention among graduates in the MRD.

Additionally, the impacts of climate change and the degradation of natural resources and the environment are increasing burdens on local socio-economic development. Therefore, this study aims to examine and build a compatible green economic model to help adapt to climate change and prevent natural disasters in the island district. The authors have researched and built a green economic model with three main activities (fishery logistics, tourism, and aquaculture), helping economic growth, improving people’s quality of life, and minimising the negative impact on the ecological system. The effectiveness of the green economic model is evaluated through a set of criteria with many contents, such as economic efficiency, the ability to create jobs and improve people’s living standards, and the level of renewable energy use, ecological and environmental conservation. In the end, groups of general and specific solutions are proposed to help strengthen the development and implementation of green economic models in the island district, ensuring adaptation to climate change, disaster prevention, and assurance of efficiency and sustainability for the environment, economy, and society.","PeriodicalId":18650,"journal":{"name":"Ministry of Science and Technology, Vietnam","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139168666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Utilising data from 2,475 non-financial firms across 19 frontier markets from 2003 to 2019, the study employs pooled OLS, fixed effects, and between-effects models to scrutinise the impact of factors like financial comparability, reputable auditing, analyst coverage, and legal systems on earnings management. The findings reveal that enhanced financial comparability, facilitated by strong governance mechanisms such as reputable auditors and analyst coverage, leads to a reduction in earnings management and information asymmetry. Interestingly, leverage does not serve as a constraining factor as commonly believed. The results contribute to the growing body of literature on the application of data science, and challenge the pecking order theory (POT), while lending support to the knowledge-based view (KBV)and convergence theories, thereby offering valuable insights into the role of corporate governance in mitigating information asymmetry.","PeriodicalId":18650,"journal":{"name":"Ministry of Science and Technology, Vietnam","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139170398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, smart factories have attracted the attention of not only business owners and policymakers but also scholars in many fields of research. However, the conception of a smart factory varies significantly depending on the approaches. This discrepancy translates into a notable divergence in creating a development strategy for a smart factory, encompassing aspects such as technology selection for investment, the enhancement of human resource strategies, and the overall development strategy for the entire enterprise. Furthermore, this disparity poses challenges in proposing a consistent science and technology policy to promote the trend of intelligent production. To address these shortcomings, the authors conducted an exhaustive literature review of published works on smart factories toestablish a comprehensive concept and delineate the primary characteristics of smart factories, providing a fundamental framework for strategic planning and investment policies.

Constructing a knowledge-based economy hinges on four pillars: the environment, the education system, the information infrastructure, and the innovation system. Consequently, education plays an integral role, particularly at the university level. To evaluate the educational process at universities, the academic achievements of students are consistently considered. Currently, across universities in general and An Giang University in particular, there is an escalating number of students experiencing poor academic performance, which leads to academic indebtedness, re-examinations, and delayed graduation. Hence, there is an imperative need to investigate the factors influencing students’ learning outcomes within the Faculty of Economics and Business Administration at An Giang University. The primary objective of this study is to identify the factors that impact students’ learning outcomes and propose measures for enhancing these outcomes. The research encompasses two phases: qualitative research and quantitative research. Following the survey and data cleansing procedures, the sample size for analysis comprises 350 observations. The analysis outcomes reveal that four variables exhibit a positive correlation with students’ learning outcomes: family and societal factors, scholarships, infrastructure, and motivation. The results of this research are intended to serve as practical documents that can assist academic leaders in making informed decisions to enhance the quality of education within the faculty.","PeriodicalId":18650,"journal":{"name":"Ministry of Science and Technology, Vietnam","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139168406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
