This paper aims to determine the perception of small and medium-sized enterprises (SMEs) employees regarding the usage of cloud computing services in their activities. The quantitative study was conducted on a sample of 315 respondents employed in Romanian SMEs. Testing of the conceptual model was performed with the WarpPLS 3.0 software. The study aimed to test how several constructs—the perceived benefits, disadvantages and risks, communication process, overall experience of using cloud computing services, perceived image, and empathy regarding the cloud computing services—influence the perception of the cloud computing service quality among SMEs employees. Moreover, employees’ perception regarding the satisfaction of using cloud computing services based on the perceived quality was also tested. We concluded that the perceived benefits and disadvantages of cloud computing service usage, the perception of both the communication process and users’ experience regarding cloud computing service use, empathy, and cloud computing service image positively influence the perceived quality of the cloud computing service usage in SMEs. We did not find evidence that the perceived risks significantly influence the perceived quality of cloud computing services. Finally, we demonstrated that the perceived quality of the cloud computing services positively influences the satisfaction regarding cloud computing services among SMEs employees.

The purpose of this paper is to illustrate the opportunities for adopting robotic applications, through a marketing mix perspective, as well as depicting the current state of industrial robot integration in Romanian enterprises and the labor market, in contrast to other economies of the European Union. In this research, we highlight the impact of industrial robots within enterprises, while also considering the perceived standard of living through GDP per capita. For this, we conducted exploratory research based on secondary data regarding the evolution of the robotics sector in Romania, in connection to the dynamics of the global and European Union robotics market. We also performed a principal components analysis, which revealed the main factors that contributed to the dynamics of nation-level enterprise statistics. Our analysis revealed that a higher integration of industrial robots contributed to the reduction of employment rates amongst all six EU countries considered, while also having positive correlations with the GDP per capita and apparent labor productivity. Mixed results were only observed for the impact of industrial robots on remuneration growth, suggesting the potential adverse effects automation could have on incomes.

Giving due consideration to sustainability, the new concept of bioeconomy has faced strong support from international policymakers, changing the way the economy is currently working. And it does not involve only the replacement of fossil feedstock with bio-based fuels, but also acquiring value from waste and bringing to light the resource efficiency that can lead to a smooth transition from a linear to a circular economy. This paper aims to track the EU states movement in implementing the bioeconomy best practices by building clusters based on their progress in adapting their industries to the new requirements. To make this possible, we created two scenarios for recording the evolution of the energy industry in 27 countries: the first one that groups them according to the fossil-fuel sources, and the second one based on renewable resources. Our results revealed that the biomass tends to be used as a complementary source and not a substitute, in comparison to the traditional fuels. Same actors keep the leading positions in both scenarios, making us believe that they may face strong challenges in reaching the European Commission goals. Thus, the present study emphasizes the need to develop highly efficient policies for all EU members to keep the same path.
