When Vaccine Uncertainty Prevails: Association Between Online Social Influence and COVID-19 Vaccine Intentions

Guided by the integrative model of behavioral prediction and the social identity of deindividuation effects model, this study used an online experiment (N = 322) to test a moderated-mediation model that linked exposure to user comments posted to COVID-19 vaccine news stories and vaccine intentions. The study was conducted in Vietnam when the Delta variant of COVID-19 spread to the country and the efficacy and side effects of the COVID-19 vaccine were controversial in the news. Results showed that, compared with vaccine-hesitancy comments, vaccine-acceptance comments significantly increased vaccine intentions through injunctive norms, response efficacy, and attitudes. This indirect association was only significant among participants who perceived commenters as in-group members. Compared with vaccine-hesitancy comments, a mixture of comments that featured both acceptance and hesitancy significantly increased perceived norms, perceived efficacy, and attitudes. Further, comments significantly changed participants’ perceived norms, perceived efficacy, and attitudes compared with the news stories. Theoretical and practical implications are presented

The impact of ownership structure on corporate performance (business-operating result) of listed companies on Ho Chi Minh Stock Exchange – A comparison the period 2006-2008 vs 2015-2017 – 10 years overview

This research studies the relationship between equity structure and business performance/ operating results of listed companies on HOSE for three years 2015, 2016, and 2017. This is not only an important aspect of corporate governance but also more important for companies operating in the form of a joint-stock company. The author uses the Enterprise Management System theory and references Xu and Wang's research model applied to Chinese joint-stock companies (1997). The used data is secondary data including indicators showing the company's business results (ROA, ROE, P/B) and equity ratios of shareholders (ownership concentration, ownership components). The research method was performed by regression analysis using SPSS software, in which the dependent variables are indicators of the company's business results, the main independent variables represent the equity structure. After analyzing data, the study has drawn two main results. The first result is that the ownership component of individuals (personal) hurts on the business performance of companies, in contrast to the fraction of equity owned by state and equity owned by legal person/institution (organizational entities) do not have any influence on the linear correlation. The second result is the concentration of ownership has no relation to the business performance of companies. With the above results, this topic can be studied more extensively for all types of other ownership such as domestic shareholders and foreign shareholders; due to both two types increasingly essential for companies and investors in the joint-stock market

Ensuring the Semantic Correctness of Workflow Processes: An Ontological Approach

International audienceWorkflow verification has been known as an important as-pect of workflow management systems. Many existing approaches con-centrate on ensuring the correctness of workflow processes at the syntac-tic level. However, these approaches are not sufficient to detect errors at the semantic level. This paper contributes to ensure the semantic cor-rectness of workflow processes. First, we propose a formal definition of semantic constraints and an O(n 3)-time algorithm for detecting redun-dant and conflicting constraints. Second, by relying on the CPN Ontology (a representation of Coloured Petri Nets with OWL DL ontology) and sets of semantic constraints, workflow processes are semantically created. And third, we show how to check the semantic correctness of workflow processes with the SPARQL query language

Ensuring the Correctness of Business Workflows at the Syntactic Level: An Ontological Approach

International audienceHigh quality business workflow definitions play an important role in the organization. An incorrectly defined workflow may lead to unexpected results. Therefore, each business workflow definition should be carefully analyzed before it is put into use. In this paper, we propose an ontological approach which is suitable for ensuring the syntactic correct-ness of business workflows. In details, to represent CPNs with OWL DL, we first introduce the CPN Ontology. Then, we define axioms, which are added to the CPN Ontology to provide automated support for establishing the correctness of business workflows. Finally, by relying on the CORESE semantic engine, SPARQL queries are implemented to detect shortcomings in concrete workflows. To the best of our knowledge, this is a novel approach for the representation and verification of business workflows based on ontologies

Representation of RDF-oriented Composition with OWL DL Ontology

International audienceThis paper introduces a solution for representing RDF-oriented compositions with OWL DL ontologies. Firstly, we present an overview of RDF-oriented Composition Definition Language (RDFCDL), which is defined for creating/composing RDF manipulation operations. Secondly, we propose an approach for representing RDFNet with OWL DL ontology. We focus on translating some key components of the RDFCDL language into classes, properties and axioms of OWL DL ontology

Coloured Petri Nets-based Approach for Manipulating RDF Data

International audienceThis paper introduces a solution for controlling RDF data manipulation operations. We propose a formal approach to manage any modification, query or adaptation of the data to satisfy end-user/application criteria (e.g., RDF filtering). An overview of the RDF data manipulation framework with its main components is first presented. We then introduce the RDF-oriented Composition Definition Language (RDFCDL) including the syntax and its graphical representations defined based on CPNs. The language aims to support both expert and non-expert developers to create/compose RDF manipulation operations. Besides, an ontology for representing processes modelled with the RDFCDL language is developed in order to share and reuse the processes more easily. To the best of our knowledge, this is the first approach providing a means for end-users to create activity nodes over RDF data based upon system-defined functions and allowing manipulating processes to be stored in RDF file format

Synthesis of antiulcer drug esomeprazole.

Esomeprazole (Nexium®), the (S)-isomer of Omeprazole, is the first proton-pump inhibitor developed as a single isomer for the treatment of acid-related diseases. It is used for the treatment of peptic ulcers, gastroesophagal reflux disease, and erosive esophagitis. Herein, we report our synthetic study of esomeprazole sodium salt from the starting    2-mercapto-5-methoxybenzimidazole and 2-(chloromethyl)-4-methoxy-3,5-dimethylpyridine hydrochloride reagents. The Esomeprazole sodium salt was obtained from enantioselectivesulfoxidation reaction in moderate yield with high enantioselectivity

Teaching English vocabulary to young learners through total physical response method

This study attempts to investigate the effect of the Total Physical Response (TPR) Method on vocabulary retention and explore the young learners’ attitudes toward it. It involved sixty two English young learners (YLs) aging from 10 to 11. All of them were attending English classes at Viet Uc English Language Center (henceforth called VUC) in Bien Hoa City where the current study was conducted. Both quantitative and qualitative data was obtained through the three instruments, namely pre- and post-test and interview. Descriptive statistics was employed for data analysis. The results revealed that TPR had effect on the YLs’ vocabulary knowledge through an increase in their vocabulary retention after they underwent the treatment. Similarly, the findings of the study also revealed that the YLs had positive attitudes toward the use TPR in vocabulary teaching and learning. This study is expected to shed light to the implementation of teaching vocabulary methods in the VUC context and other similar contexts
