This research was conducted to understand how vulnerable communities used social media (SM) tools to face the impacts of the COVID-19 pandemic. Affected by the lack of information and the absence of effective public policies, residents from slums in the city of Rio de Janeiro displayed new and unexpected uses to SM tools to tackle the health and socio-economic impacts of the pandemic.

The research methodology consisted of a qualitative, exploratory study, combining a series of in-depth interviews with the analysis of various posts, containing videos and texts, extracted from SM during the first six months of the pandemic. The data were collected in the context of 10 different communities in Rio de Janeiro city.

In the context of the pandemic, people combined different uses of SM not only to inform themselves and communicate with others but also to articulate and execute fundraising and food donation strategies within vulnerable communities. Accordingly, this SM use is characterized by improvisation, learning by doing and building resilience, which are all constructs related to the concept of bricolage. Users had no specific SM knowledge, and adjusted these technological tools to emergent new activities in practice, which is characteristic of sociomaterial process. In addition to emphasizing the importance of context for the emergence of the phenomenon, this work also highlights reliability, validity and authority as characteristics related to the citizen-led participation approach that was observed.

Future research can develop approaches based on pandemic sociomaterial bricolage (PSB) aspects, which could guide governments and practitioners on building innovative solutions for the use of SM by the population, especially in emergency situations.

This study proposes a framework, termed PSB, to represent SM usage promoted by the pandemic context, which emerged from the triangulation of empirical data and an analysis based on the concepts of bricolage and sociomateriality.

This chapter presents a methodological discussion about ethnographic practice from a feminist perspective that contributes to the field of communication studies methodology and theory. The ethnography engages Black (Afro-Brasileiro and African-American) and economically disadvantaged youth from Rio de Janeiro (Brazil) and New Orleans (USA) regarding their strategies of social and media visibility. This multi-sited ethnography proposes to improve the objectives of ethnography through theoretical flexibility, liberation from a priori assumptions, greater representation of the voices of community members, disavowal of the imperatives of positivist work, and abiding respect for the “other.”

To address the absence of Lean in transportation logistics in the digital era, this study aims to investigate the application of Lean transportation (LT) tools to reduce waste and facilitate the digital transformation of dedicated road transportation in the offshore industry.

The study adopts action research with a multimethod approach, including a scoping review, focus groups (FG) and participant observation. The research is conducted within the offshore supply chain of a major oil and gas company.

Implementing LT’s continuous improvement tools, particularly value stream mapping (VSM), reduces offshore transportation waste and provides empirical evidence about the intersection of Lean and digital technologies. Applying techniques drawn from organisational learning theory (OLT), stakeholders involved in VSM mapping and FGs engage in problem-solving and develop action plans, driving digital transformation. Waste reduction in loading and unloading stages leads to control actions, automation and process improvements, significantly reducing downtime. This results in an annual monetary gain of US$1.3m. The study also identifies waste related to human effort and underutilised digital resources.

This study contributes to theory and practice by using action research and LT techniques in a real intervention case. From the lens of OLT, it highlights the potential of LT tools for digital transformation and demonstrates the convergence of waste reduction through Lean and Industry 4.0 technologies in the offshore supply chain. Practical outputs, including a benchmarking questionnaire and a plan-do-check-act cycle, are provided for other companies in the same industry segment.

In our studies of daily newspapers and news websites in small and medium-sized cities in Brazil, we view these enterprises as firms endowed with specific strengths and weaknesses reflecting the characteristics of the localities in which they operate. In addition, we use references from urban geography and the industrial economy to investigate their structure, conduct, and performance. This chapter presents our observations about the structure of these firms and the journalistic business in non-metropolitan cities of the State of Rio de Janeiro. The results point to greater consolidation of newspapers, despite their traditional way of operating; the low performance of news websites and their restricted source of revenue; and the existence of a potential regional market little explored by these media.

This paper aims to identify the kind of internal climate leaders should offer health-care professionals to promote a patient safety culture in public hospitals managed by social health organizations in Brazil.

Two surveys were applied to health-care professionals working at three Brazilian public hospitals. The internal climate survey reached 1,013 respondents, and the patient safety culture survey reached 1,302 participants. Both factor and regression analyses were used to analyze the study model and determine how internal climate influences patient safety culture.

Results indicate that to promote a patient safety culture among health-care professionals, leaders should generate an internal climate based on trust to foster pride in working in the hospital. Possibly, the trust dimension is the most important one and must be developed to achieve job satisfaction and provide better services to patients.

All the hospitals studied were managed by the same Organização Social de Saúde. Due to the limited responses concerning the respondents’ profiles, demographic variables were not analyzed.

This research reveals that the trust and pride dimensions can most strongly influence a positive patient safety culture, helping hospital leaders face this huge managerial challenge of consistently delivering high standards of patient safety.

This research studies the promotion of a patient safety culture in public hospitals managed by social health organizations, characterized by greater flexibility and autonomy in health-care management and by a greater need for accountability.

The purpose of this paper is twofold: first, to present a rigorous bibliometric analysis and a systematic literature review of the critical success factors (CSFs) for Building information modelling (BIM)-based digital transformation; second, to identify the relationship between the dimensions in favour of BIM implementation.

This study adopts a two-step approach to combine bibliometric and systematic literature review to explore the research topic of BIM and CSFs. Bibliometric tools such as Biblioshiny in R language and Ucinet software were applied to this study.

Besides identifying the two most influential authors (e.g. Bryde and Antwi-Afari), the key journal for disseminating articles, and the most influential countries in this discourse (e.g. Hong Kong and Australia), the study also identifies four pivotal research themes derived from the co-occurrence analysis of keywords: the fusion of sustainability and technology with BIM; practical application and its integration within construction management; innovation and engineering paradigms; and the advent of emerging technologies (e.g. Blockchain) within developing nations. Additionally, the paper introduces a comprehensive framework for selecting CSFs pertinent to BIM-centred digital transformation as viewed through the lens of dynamic capabilities.

This paper establishes a link between dynamic capabilities theory, CSFs, and BIM dimensions, presenting a multifaceted framework guiding future paths and offering practical insights for managerial and political decision-makers engaged in digital transformation endeavours. The study positions dynamic capabilities as pivotal, aligning digital technologies with continuous business performance, and advocates for a strategic focus on digital transformation.

The current and modern electrical distribution networks, named smart grids (SGs), use advanced technologies to accomplish all the technical and nontechnical challenges naturally demanded by energy applications. Energy metering collecting is one of these challenges ranging from the most basic (i.e., visual assessment) to the expensive advanced metering infrastructure (AMI) using intelligent meters networks. The AMIs’ data acquisition and system monitoring environment require enhancing some routine tasks. This paper aims to propose a methodology that uses a distributed and sustainable approach to manage wide-range metering networks, focused on using current public or private telecommunication infrastructure, optimizing the implementation and operation, increasing reliability and decreasing costs.

Inspired by blockchain technology, a collaborative metering system architecture is conceived, managing massive data sets collected from the grid. The use of cryptography handles data integrity and security issues.

A robust proof-of-concept simulation results are presented concerning the resilience and performance of the proposed distributed remote metering system.

The methodology proposed in this work is an innovative AMI solution related to SGs. Regardless of the implementation, operation and maintenance of AMIs, the proposed solution is unique, using legacy and new technologies together in a reliable way.

This chapter presents a comparative study of the trends and patterns of communication and tourism research in Brazil and the United States over the last 20 years. Through a bibliometric analysis of the CAPES and EBSCO databases, the study identifies the main theoretical and methodological references, classifies the fundamental themes in the area, and describes the role of communication for tourism. The results indicate the predominance in North American scientific literature of research related to the image and the brand of the tourist destinations, as well as the measurement and the evaluation of the communicative strategies. On the other hand, Brazilian research presents a greater diversity of approaches: destination image studies, tourism consumption, tourist narrative analysis, identities, social networks, community-based tourism, sports, and ecological tourism, with an explicit recognition of the dangers of sexual objectification and dehumanization within tourism. The survey showed that the scientific community has a strong interest in this area, signaling a search for knowledge to deepen the conceptual understanding of the subject. Thus, this chapter provides insights regarding the opportunities and directions for the next decades of research in this field of study.

Brazil’s regional inequality is an important topic due to the large and persistent differences in development between states and the high levels of inequality in the country. These variations in development can potentially render survey data inaccurate since the significance of capital income varies across the states. Besides, previous studies incorporating tax and national accounts data globally have mainly focused on measuring the income distribution at the country-level. This approach can limit the understanding of inequality, especially when considering large countries such as Brazil.

The methodology used to construct these estimates follows the guidelines of the Distributional National Accounts, whose core goal is to provide income distribution measures consistent with macroeconomic aggregates and harmonized across countries and time. The procedure has three main steps: first, it corrects the survey’s underrepresentation of top incomes using tax data. Then, it accounts for national income items not included in the survey or tax data, such as imputed rents and undistributed profits. Finally, it ensures that all components match the national income.

Compared to survey-based estimations, the results reveal a new angle on the state-level inequality. This study indicates that Amazonas, Rio de Janeiro and São Paulo have a more concentrated income distribution. The top 1\% of earners in these states receives around 28\% of total pre-tax income, while the top 10\% receive nearly 60\%. On the other end, Amapá (AP), Acre (AC), Rondônia (RO) and Santa Catarina (SC) are the states where the income distribution is less concentrated. There were no significant changes in the income distribution across the states during the period analyzed.

This study combines survey, tax and national accounts data to construct new estimates of Brazil’s state-level income distribution from 2006 to 2019. Previous results only considered income captured in surveys, which usually misses a significant part of capital incomes. This limitation may bias comparisons as capital income has different importance across the states. The new estimates represent the income of top groups more accurately, account for the entire national income and enable to compare regional inequality levels consistently with other countries.
