ABSTRACT
The purpose of the study is to analyze the development of the scientific production of teamwork, in relation to the performance and productivity of employees, and to distinguish whether the Covid-19 period has affected it. The Web of Science database was used to collect the articles and the methodology used was bibliometric, covering the period from 1993 to December 2021 with 305 articles. Bibliometrix and VOSviewer were used to obtain data for the detailed analysis of results such as world scientific production, areas of knowledge, most cited articles, by language, authors and relevant sources and impact, network of cocitations, keywords, classification of empirical-theoretical methodologies and theories that support the documents. In terms of results, it is highlighted that the predominant area was economic business, the most used methodology was empirical, and in terms of theories supporting the articles, role theory stands out. As for Covid-19, although in previous years the production showed an increase, it can be emphasized that in the last two years there has been a significant increase.
ABSTRACT
During the COVID-19 pandemic, the U.S. power sector witnessed remarkable electricity demand changes in many geographical regions. These changes were evident in population-dense cities. This paper incorporates a techno-economic analysis of energy storage systems (ESSs) to investigate the pandemic's influence on ESS development. In particular, we employ a linear program-based revenue maximization model to capture the revenues of ESS from participating in the electricity market, by performing arbitrage on the energy trading, and regulation market, by providing regulation services to stabilize the grid's frequency. We consider five dominant energy storage technologies in the U.S., namely, Lithium-ion, Advanced Lead Acid, Flywheel, Vanadium Redox Flow, and Lithium-Iron Phosphate storage technologies. Extensive numerical results conducted on the case of New York City (NYC) allow us to highlight the negative impact that COVID-19 had on the NYC power sector. © 2023 IEEE.
ABSTRACT
The article aims to present the development of the existing scientific literature on teleworking and identify whether Covid-19 has had an impact on scientific production in the Scopus and Web of Science databases. The methodology used to develop this research is based on a bibliometric study between the period from 1977 to October 29, 2020, in which a total of 1667 documents were reviewed through the Bibliometrix and VOSviewer software, including articles, book chapters and books. The analysis that was performed on the documents was at the level of authors, sources, documents, and keywords through the number of documents, citations, H-index, Bradford's law, Lotka, in addition to co-citation and co-authorship networks. Ultimately, scientific production has increased little by little over the years, however, Covid-19 caused this production to increase considerably. Most of the documents written on the subject are produced in collaboration and originate mostly in the United States and the United Kingdom, with Latin American countries lagging far behind in the production of teleworking documents.
ABSTRACT
Introduction: The pandemic caused by COVID-19 forced to change the modality in the rehabilitation processes-from face-to-face to remote-including that of those already planned treatments. Objectives: To implement telerehabilitation and to set down whether the change of modality based on therapeutic exercise impacts on the results of the intervention. Case report: The case of a patient with bilateral hip osteoarthritis is reported here. Her physical therapy intervention had to be modified to a remote modality, due to the COVID-19 pandemic. Conclusions: The remote modality adopted did not affect the functional recovery established in the early stages. It is recommended to use functional evaluations, as well as to consider the required conditions at home to continue the interventions. © 2021, Editorial Ciencias Medicas. All rights reserved.
