Radiology During the COVID-19 Pandemic: Mapping Radiology Literature in 2020

Objectives: Our aim was to assess articles published in the field of radiology, nuclear medicine, and medical imaging in 2020, analyzing the linkage of radiology-related topics with coronavirus disease 2019 (COVID-19) through literature mapping, along with a bibliometric analysis for publications. Methods: We performed a search on Web of Science Core Collection database for articles in the field of radiology, nuclear medicine, and medical imaging published in 2020. We analyzed the included articles using VOS viewer software, where we analyzed the co-occurrence of keywords, which represents major topics discussed. Of the resulting topics, literature map created, and linkage analysis done. Results: A total of 24,748 articles were published in the field of radiology, nuclear medicine, and medical imaging in 2020. We found a total of 61,267 keywords, only 78 keywords occurred more than 250 times. COVID-19 had 449 occurrences, 29 links, with a total link strength of 271. MRI was the topic most commonly appearing in 2020 radiology publications, while “computed tomography” has the highest linkage strength with COVID-19, with a linkage strength of 149, representing 54.98% of the total COVID-19 linkage strength, followed by “radiotherapy, and “deep and machine learning”. The top cited paper had a total of 1,687 citations. Nine out of the 10 most cited articles discussed COVID-19 and included “COVID-19” or “coronavirus” in their title, including the top cited paper. Conclusion: While MRI was the topic that dominated, CT had the highest linkage strength with COVID-19 and represent the topic of top cited articles in 2020 radiology publications.

Multivocal Literature Mapping on DSLs and Tools for Entity-Relationship Modeling

A variedade de tecnologias de sistemas de banco de dados que se tornou disponível nos últimos anos dificulta a seleção de ferramentas para modelagem de entidade-relacionamento (ER). Nesse sentido, contribui-se com um levantamento de inovações recentes por meio de um mapeamento sistemático complementado por uma pesquisa na literatura cinza. Este trabalho abrange um conjunto final de 10 estudos primários focados em Linguagens Específicas de Domínio (DSL) e identifica 55 ferramentas já aplicadas na indústria e academia para modelagem ER em nível conceitual, lógico e físico. Assim, este estudo apresenta o estado da arte e da prática para modelagem ER, incluindo sua caracterização e lacunas de pesquisa.

Payment for Environmental Services for Waste Pickers: Systematic Literature Mapping

In Payment for Environmental Services (PES) systems, environmental service providers receive compensation for a conservationist action that implies the preservation of natural resources. The objective of this systematic mapping was to identify and discuss scientific articles that address the theme 'Payment for Environmental Services - PES for Waste Pickers Organizations', to understand the state of art of hiring these workers as environmental service providers. The study was developed using the method of systematic mapping of literature, from 2009 to 2019, considering qualitative and quantitative aspects. Results indicated that the countries that most investigate this theme are Brazil, China, India, and Indonesia. The articles portray the informal work of waste pickers, working conditions and the transition from informal systems to waste management in public services. The relationship between payment for environmental services and the work of waste pickers is not yet evident. Furthermore, research on PES and recycling are developed along distinct lines, without interdisciplinarity. However, PES shows itself as an important socio-environmental management tool that has the potential to solve relevant problems of recyclable waste management, because it presents congruent characteristics with the public procurement systems for waste pickers.

Design for Disassembly (DfD) in construction industry: a literature mapping and analysis of the existing designs

A systematic search of scientific literature on the topic of Design for Disassembly (DfD) in the architecture, engineering, and construction (AEC) industry was performed with a special focus on study cases. The results were augmented by electronic magazine search due to the non-representative amount of data found in the scientific database. Results show the domination of wood and steel solutions among architects and engineers designing for disassembly. Frame structural system is preferable. DfD structures are mainly located in Europe but observed in the whole world and growing exponentially since 90'. The database with 117 built DfD study cases is made available online and will be further developed.

Towards Unified Literature Representations: Applications in Information Systems and Entrepreneurship Research

Research activity is becoming increasingly complex due to the nature of research topics and questions. Among the essential academic research activities are literature reviews (LR), as they support the advance of the knowledge frontier. To improve literature reviews and their understanding, it would need to have comprehensive literature representations. In this perspective, the paper aims to advance previous work by illustrating a new way of creating thorough literature representations. The proposed tool is innovative and versatile since authors can adopt it in different types of LRs. Its adoption implies the construction of a three-dimensional scheme for the classification of the literature to be analysed. Then, based on the latter and selecting suitable evaluation variables, the proposed approach produces informative multidimensional representations for literature mapping and bibliometric analysis. For exemplifying this, the paper provides two application cases concerning Enterprise Resource Planning (ERP) systems and entrepreneurship research.
