An Ontological-based Model for Competences in Sustainable Development Projects: a Case Study for Project’s Commercial Activities

The paper presents a project management competencies model, using an ontological approach. The ontology, named PMCatalog, was developed in the framework of the project CONTO, financed by Romanian through the grant 91-037/2007. PMCatalog is consistent with the competence definition and PM competence elements included in the International Competence Baseline, the competency standard of the International Project Management Association. The main PMCatalog’s use cases for commercial activities in sustainable development projects are described. Ontology was developed using the Protégé editor.competence, project management, sustainable development, commercial activities

OBJECT ORIENTED MODELLING, A MODELLING METHOD OF AN ECONOMIC ORGANIZATION ACTIVITY

Now, most economic organizations use different information systems types in order to facilitate their activity. There are different methodologies, methods and techniques that can be used to design information systems. In this paper, I propose to present the advantages of using the object oriented modelling at the information system design of an economic organization. Thus, I have modelled the activity of a photo studio, using Visual Paradigm for UML as a modelling tool. For this purpose, I have identified the use cases for the analyzed system and I have presented the use case diagram. I have, also, realized the system static and dynamic modelling, through the most known UML diagrams

CLUSTER ANALYSIS OF PC ENDOWMENT IN PRE-UNIVERSITY EDUCATION AT ROMANIAN COUNTIES LEVEL

In the contemporary world, ICT has become omnipresent. Not only the younger generation, but also the other categories of the population uses it in their daily activity, on the one hand. On the other hand, however, in many counties, the education and, especially, the pre-university education remained deficient regarding the endowment of schools with personal computers (PCs) and other ICT. Based on this observation, this paper analyses the endowment with PCs of pre-university educational institutions at county level and their grouping by the average number of existing PCs. The paper emphasizes the major differences that exist between counties, in this regard

Analysis of Disparities in Internet Purchases by Individuals at the EU State Level

In recent years, the trend of digital transformation of commerce has been extremely dynamic, and the COVID-19 pandemic has generated a strong impetus for the development of digitalization. However, there is a large difference in the use of e-commerce in European Union (EU) countries. The objective of this article is to explain the complex evolution of e-commerce in terms of B2C using econometric methods, especially regarding Internet purchases made by individuals according to six social and technological factors considered basic factors in purchase decisions. Thus, we propose a conceptual model for the analysis of disparities in Internet purchases, taking into account both factors related to demand (consumer) and factors related to supply (supplier). Based on the data provided by Eurostat for all 27 EU countries for the period 2012–2021, the empirical findings of cluster analysis suggest changes in the grouping of countries at the beginning and end of the analysed period. Socioeconomic factors that can explain the transition of EU states from one group to another in terms of development level of Internet purchases by individuals were identified. The results of this study can serve as a starting point for future adaptation strategies of e-commerce in the context of global economic development with a focus on increasing digitisation, the existence of for which a digital convergence in the process of digital transformation is essential

Characteristics of the evolution of renewable energy production in European Union

Starting from the evolution of the primary energy production from renewable energy sources, in the EU-28, from 1990 to 2015, the paper emphasizes both the changes in the primary production volumes and the mutations in the share of their production in the total primary renewable energy production recorded, especially, in the second part of the analysed period. Based on them, models are identified and primary renewable energy productions for 2020 are estimated from renewable energy sources like: solid biofuels, hydropower, wind power, biogas, biodiesels and solar photovoltaic. Excepting the production of energy based on hydropower, significant increases are recorded for the other five renewable energy sources

A Cluster Design on the Influence of Energy Taxation in Shaping the New EU-28 Economic Paradigm

Environmental and energy taxation are essential components for designing global economic policies and they often contribute to achieving the sustainable economic development goals in contemporary economies. Starting from the analysis of certain elements such as the share of environmental, energy, transport and pollution taxation in GDP and using the Hierarchical Clustering methodology, the paper aims to identify economic models of behaviour and to understand the influence of energy taxation in designing an economic paradigm. In addition, another objective of the paper is to deepen the relationships that energy taxation has in designing certain economic models of behaviour and to group the EU-28 Member States based on the specified criteria. The research results confirm that at the EU-28 level could exist elements for achieving energy taxation convergence and that the states should promote a more accurate fiscal policy in order to improve the loss of competitivity caused by an inaccurate energy taxation

Exploring Digital Literacy Skills in Social Sciences and Humanities Students

Digital literacy is among the mandatory abilities to any higher education level and represents a fundamental ingredient in successful professionalization. Considering the deep penetration of digital technologies in everyday life, digital literacy offers a set of transversal skills that could improve a whole area of activities, from banking operations to civic participation. However, these skills are diverse and vary according to the development of technologies and society. This study fills an important academic gap on digital literacy by placing it in a specific and well-defined context, analyzing different perspectives that involve such learning, such as predictors of digital literacy in different types of students. In addition, research increases its importance as it is being developed during the pandemic, a period characterized by accelerated technological use and sudden changes. This research used a quantitative design based on the answers to a questionnaire conducted from March 2021 to May 2021. From a methodological perspective, we tested several hypotheses using one-way analysis of variance (ANOVA) and confirmatory factor analysis (CFA) within the structural equation model (SEM). The results show that communication, critical thinking, problem-solving, and technical digital skills are more present in the case of students enrolled in social sciences, while other digital skills (i.e., creativity and information) are more prevalent in the case of humanities students. Moreover, the results showed that, except for creativity and problem-solving-related digital skills, all of the digital skills were significantly influenced by students’ different levels of education
