Information and communication tools (ICT), Web 2.0 applications and the impact that these resources are having on education are rapidly creating new challenges for teachers and learners faced with learning online. Teaching and learning in an e-learning environment happens differently than in the traditional classroom and can present new challenges to professors and learners participating in this online learning environment. Objectives: The purpose of this article is to provide a framework for teachers for a better e-interaction with students. Approach: It shows the literature and research that focus on e-learning statistics.ResultsContinuing to learn and try new methods of communication will aid in improved learning and foster teacher-student respect and collaboration. Value: There are effective techniques to presenting face-to-face material in the online environment that will allow the student to achieve a higher level of satisfaction of learning and cognitive understanding of the course material

While e-government (referring here to the first generation of e-government) was just the simple manner of delivering public services via electronic means, e-gov 2.0 refers to the use of social media and Web 2.0 technologies in government operations and public service delivery. However, the use of the term ‘e-government 2.0’ is becoming less common as the focus shifts towards broader digital transformation initiatives that may include AI technologies, among others, such as blockchain, virtual reality, and augmented reality. In this study, we present the relatively new concept of e-government 3.0, which is built upon the principles of e-government 2.0 but refers to the use of emerging technologies (e.g., artificial intelligence) to transform the delivery of public services and improve governance. The study objective is to explore the potential of e-government 3.0 to enhance citizen participation, improve public service delivery, and increase responsiveness and compliance of administrative systems in relation to citizens by integrating emerging technologies into government operations using as a background the evolution of e-government over time. The paper analyzes the challenges faced by municipalities in responding to citizen petitions, which are a core application of local democracies. The author starts by presenting an example of an e-petition system (as in use today) and analyses anonymized data of a text corpus of petitions directed to one of the Romania municipalities. He will propose an AI model able to deal faster and more accurately with the increased number of inputs, trying to promote it to municipalities who, for some reason, are still reluctant to implement AI in their operations. The conclusions will suggest that it may be more effective to focus on improving new algorithms rather than solely on ‘old’ technologies.

Cities around the world should prioritize the management of municipal solid waste (MSW). For this to be effective, there is a strong need to buildup a complex system that involves social, economic, and environmental processes, leading to a supply chain (SC). The actors involved in dealing with MSW—from suppliers, collectors, distributors, industries, and managers—should be engaged in strategic planning. This paper focuses on alternative energy solutions and uses existing SC models of managing MSW, as well as the existing literature, to identify successful stories in cities like Bergen and Tønsberg in Norway, London in UK and Barcelona in Spain and draw a conceptual framework for city officials in Romanian municipalities (but not only) to innovate—and convert MSW in biogas to be used in delivering public services, i.e., public transportation. The article shows that when the innovation is accepted and well implemented by all actors, the benefits for the citizens and the municipality are considerably higher than by using conventional methods of collecting and depositing MSW. The proposed approach is also relevant for implementing the EU environment policy, where delays are usually observed (as the case for Romania).

The promotion of new electric and hybrid vehicles is a worldwide strategy to reduce carbon emissions for a clean future environment in many countries. In Europe, development of the electric vehicle (EV) industry is a strategic direction of multiple car-producing companies, institutes, and governments, but how sustainable it is to shift fully to electric has yet to be seen. By making use of the statistic reports from the European Union, scientific literature, and mathematical calculation, the author wants to examine if what politicians see will be a matter of reality in the near future. It will be proved that, if all private transport become electric, energy consumption will increase to such a level that is impossible to be satisfied by the actual energy producing companies. While the EV industry is seen as an important step towards achieving environmental goals, and despite some positive assumptions made by few European Governments (e.g., Norway) according to which electrical cars will replace the fossil fuel ones in private transportation, the actual energy market trends are not able to support the demand for the next several decades. The author will focus on one European country, Romania, to provide it as a case study (Romania is a self-sustainable country with regard to energy production, producing roughly 124% of its needs.).

Over recent decades, the transformation of education through technology has created a more extensive tool for enhancing the Bologna process for increasing the quality, effectiveness and accessibility of higher education. In this context, literature supports the importance of Web platforms for education, in particular through comparative analysis, focusing on educational effectiveness and promoting quality education. Few studies have integrated the analysis with the economic issues. This paper aims to achieve a comparative study of Web platforms, in terms of raising the effectiveness of distance education, and the economic costs required to implement them. The research methodology is using, for the first time, an adapted version of cost-effectiveness analysis. Empirical research will be carried out on two platforms of e-learning - Learning Management System (LMS) and Moodle - used by our university to support distance education programs. The working hypothesis starts from the fact that open source software is cheaper than that developed internally, even if it does not fully meet the needs of the university

The topic investigated in this article is a comparison, contrast, and integration effort of European strategies for sustainable development with the evolving market initiatives that are beginning to fuel the fourth industrial revolution. Several regulatory initiatives from continental bodies come into effect to radically change access to finances for business development, based on sustainability goals, and an analysis of the legislation and trends becomes essential for an effective pivot tactic in the face of adversity, as well as change management policies to pre-emptively adapt and perform. The general research question is “what the strategic tools are best employed to overcome the hurdles laid forth by the drastic changes legally required for a sustainable future?” The research methods include a quantitative analysis of norms, regulations, and legislation, including strategic initiatives circulated in the European Union governmental bodies, integrated with qualitative research of the literature. The study finds and draws synergies between national strategies that have recently been drafted or are currently evolving with sustainability-centric initiatives such as the hydrogen initiative, the nuclear initiative, the natural gas initiative, the renewables initiative, the synthetics, and biomass initiative, the ESG initiative, the digital initiative. The findings are to contribute to the business administration field by providing an appropriate image of the organizational design model in the sustainability era, and a strategy framework to build the optimum long-term vision founded on continental regulatory initiatives that have come into effect.
