(MDPI, 2023-07) Binsaeed, Rima H.; Grigorescu, Adriana; Pătru, Ciprian Laurențiu; Yousaf, Zahid; Nassani, Abdelmohsen A.; Pătru (Grigorie), Larisa
Health crises across the globe bring dramatic changes to the lives of individuals and organizations. These crises have some psychological effects on society. The COVID-19 pandemic also caused some serious problems for individual and organizational life. Globally, the COVID-19 situation precipitated various economic and psychological issues that are far-reaching and exceptional. Health crises are increasing following the occurrence of COVID-19 due to its psychological effects on individuals worldwide. The current study highlighted the impact of COVID-19 fear on mental well-being (MWB). Most studies have examined the MWB of nursing staff and related their MWB to psychological factors. Few studies have considered the health crisis factors that are important in terms of bringing about variation in the MWB of nursing staff. Nursing staff MWB is impacted by various health crises (including COVID-19) at the global level and it has been ignored by researchers. In this study, a list of 1940 healthcare units with 6758 nursing staff was obtained. A total of 822 nurses were selected with the help of random sampling. The collected data were analyzed using correlation analysis, SPSS (statistical package for social sciences) version 23, and SEM. Thus, in this study we examined the effect of a health crisis (i.e., COVID-19) fear on the MWB of nurses. Moreover, we also examined the extent to which perceived stress (PS) influences the link between COVID-19 fear and MWB. The study's findings confirmed that COVID-19 fear shown negative effect on MWB, while PS mediated the link between COVID-19 fear and MWB.

(MDPI, 2021-10) Andronie, Mihai; Lăzăroiu, George; Iatagan, Mariana; Uță, Cristian; Ștefănescu, Roxana; Cocoșatu, Mădălina
With growing evidence of deep learning-assisted smart process planning, there is an essential demand for comprehending whether cyber-physical production systems (CPPSs) are adequate in managing complexity and flexibility, configuring the smart factory. In this research, prior findings were cumulated indicating that the interoperability between Internet of Things-based real-time production logistics and cyber-physical process monitoring systems can decide upon the progression of operations advancing a system to the intended state in CPPSs. We carried out a quantitative literature review of ProQuest, Scopus, and the Web of Science throughout March and August 2021, with search terms including "cyber-physical production systems ", "cyber-physical manufacturing systems ", "smart process manufacturing ", "smart industrial manufacturing processes ", "networked manufacturing systems ", "industrial cyber-physical systems, " "smart industrial production processes ", and "sustainable Internet of Things-based manufacturing systems ". As we analyzed research published between 2017 and 2021, only 489 papers met the eligibility criteria. By removing controversial or unclear findings (scanty/unimportant data), results unsupported by replication, undetailed content, or papers having quite similar titles, we decided on 164, chiefly empirical, sources. Subsequent analyses should develop on real-time sensor networks, so as to configure the importance of artificial intelligence-driven big data analytics by use of cyber-physical production networks.

(MDPI, 2023-03-22) Stoicescu, Vlad; Bițoiu, Teodora; Vrabie, Cătălin
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.
The Management of Municipal Waste through Circular Economy in the Context of Smart Cities Development
(IEEE Access, 2019-07-15) Aceleanu, Mirela Ionela; Șerban, Andreea Claudia; Suciu, Marta Christina; Bițoiu, Teodora
The paper focus on the topic of circular economy in the context of sustainable development, as one major objective of today's societies. Circular economy is mostly characterized by the need to improve the use of resources,by reducing waste and recycling. Under the sustainable development broader circumstances, circular economy becomes one of the important part of providing resources for the future generations, based on intra and intergenerational solidarity, having as starting points the 3 R (reuse, recirculation, recycling) and extending the lifecycle of products. Also, a circular economy is an important factor to develop the smart cities. The smart city can be understood as a sustainable city, a city well performing in economy, governance, but also in environment and living. The paper aims to identify a set of major actions recommended at the European Union level in order to promote this vision. It aims as well to highlight some of the economic and institutional barriers that might be faced at all economic levels. The EU recommendations associated with the trends of increasing the prices of raw materials and also with the need to reduce the import dependency such as better ensure the energetic security and sustainability by respecting the imperatives of environment protection, require a focus on efforts towards these directions. Starting from these approaches, we analyzed the progress achieved by Romania in the last ten years and the extent to which the country is prepared to implement an efficient management of municipal waste in order to promote the circular economy vision. Based on the progresses obtained in the last decade, we appreciate that Romanian decision makers had understood the importance of circular economy and had taken some specific action dedicated to the focus on this direction. Although some of the indicators referring to recycling show an improvement in Romania, it still has to improve performance in this field. We consider that one of the main challenges for the future in terms of circular economy refers to the further development of the sectors associated with the circularity of resource and with the emergence of employment opportunities, based both on an active involvement of public and private sectors.
Parabolic Modeling Forecasts of Space and Time European Hydropower Production
(MDPI, 2024-06) Lincaru, Cristina; Grigorescu, Adriana; Dincer, Hasan
Renewable sources of energy production are some of the main targets today to protect the environment through reduced fossil fuel consumption and CO2 emissions. Alongside wind, solar, marine, biomass and nuclear sources, hydropower is among the oldest but still not fully explored renewable energy sources. Compared with other sources like wind and solar, hydropower is more stable and consistent, offering increased predictability. Even so, it should be analyzed considering water flow, dams capacity, climate change, irrigation, navigation, and so on. The aim of this study is to propose a forecast model of hydropower production capacity and identify long-term trends. The curve fit forecast parabolic model was applied to 33 European countries for time series data from 1990 to 2021. Space-time cube ArcGIS representation in 2D and 3D offers visualization of the prediction and model confidence rate. The quadratic trajectory fit the raw data for 14 countries, validated by visual check, and in 20 countries, validated by FMRSE 10% threshold from the maximal value. The quadratic model choice is good for forecasting future values of hydropower electric capacity in 22 countries, with accuracy confirmed by the VMRSE 10% threshold from the maximal value. Seven local outliers were identified, with only one validated as a global outlier based on the Generalized Extreme Studentized Deviate (GESD) test at a 5% maximal number of outliers and a 90% confidence level. This result achieves our objective of estimating a level with a high degree of occurrence and offering a reliable forecast of hydropower production capacity. All European countries show a growing trend in the short term, but the trends show a stagnation or decrease if policies do not consider intensive growth through new technology integration and digital adoption. Unfortunately, Europe does not have extensive growth potential compared with Asia-Pacific. Public policies must boost hybrid hydro-wind or hydro-solar systems and intensive technical solutions.

(MDPI, 2022-09) Grigorescu, Adriana; Zamfir, Ana Maria; Sigurjonsson, Throstur Olaf; Carlson, Ewa Lazarczyk
Skills needed in jobs and skills mismatches are important topics for research and policy in the field of economic development and the labour market. Understanding skill needs is essential for improving education and training policies, as labour markets experience dynamic transformation driven by rapid technological progress and increased complexity of work. On the other hand, knowledge economy is considered an important driver force of economic growth. This paper aims to assess skill needs in knowledge production and transfer occupations. We analyse data from online job advertisements and from the European Skills and Jobs Survey in order to provide a comprehensive picture of skills needed in occupations related to science, technology and ICT, as well as teaching positions from higher education in Europe. We find that workers involved in knowledge production and transfer activate in highly changing and challenging working environments. They differentiate themselves by other professionals and technicians mostly by the increased need for ICT skills, problem-solving, communication and learning skills, the ability to collaborate and adaptability. Our results are relevant for designing better education and training programs targeting occupations supporting knowledge production and transfer.

Digital technology (DT) has been broadly studied in industry and in scholarly research. This study aimed to examine the use of digital technology in the attainment of strategic performance and considered the mediating role of the accounting information systems (AISs) between them. Furthermore, this study explored the moderation of digital innovation in the linkage between DT and strategic performance. For data collection, 326 questionnaires were collected, and quantitative methods and random sampling techniques were used. The results showed that digital technology is directly associated with strategic performance. The findings also confirm that AISs play a mediating role, and digital innovation plays a moderating role in the association between digital technology and strategic performance. The results of this research encourage businesses to utilize opportunities for growing advanced technologies and developments in the industry to take up novel digital technologies, to advance their digital abilities to grow to be innovation leaders, and to boost the strategic performance of their firms. This study is one of the first pieces of research to provide information on how the latest technologies could have an influence in making innovative products/services and, afterward, boost firms' strategic performance. This study also fills a gap in the literature regarding the driving factors of strategic performance by defining the mediating role of AISs and the moderating role of digital innovation in the association between dynamic factors and performance. The outcomes of this research demonstrate that AISs are extremely helpful and have an influence on the strategic performance of electronics firms.
