COVID-19 played a crucial role in the development and enlargement of learning via electronic media. Still, the recent fourth industrial revolution [Industry 4.0 (I4.0)] paved the road toward Education 4.0. In this regard, several research challenges arise, involving the preparation of gamification strategies in online learning environments. In this sense, this paper aims to investigate the relationship between technologies of I4.0 and gamification practices in online learning around the world. Specifically, to categorize the studies of the scientific literature in the area into knowledge domains and the mention of I4.0 technologies and to verify the relationship of these technologies with the different educational levels.

The preferred reporting items for systematic reviews and meta-analysis protocol was used as a research method with 130 papers included for full content analysis and obtained from the Web of Science.

The leading I4.0 technologies mentioned in the analyzed papers were simulation, Internet of Things and augmented/virtual reality, in this order. Although there are more mentioned technologies, the domain of knowledge to be applied and the educational level interfere in choosing these pillars. With this, the main findings of this relationship were exposed in a singular, modern, active, realist, technological framework to demonstrate how I4.0 relates to the practice of gamification in online educational environments.

To the best of the authors’ knowledge, this is the first study that brings together the relationship of gamification applied in e-learning with I4.0 technologies.

We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

The purpose of this paper is to investigate the effects of acai pulp consumption on biometric parameters and inflammatory biomarkers (sCD40L, CCL5, TNF-a and CRP) in apparently healthy women.

Nutritional intervention was performed with women who consumed 200 g of acai pulp daily during 30 consecutive days. Firstly, they were divided into two groups: normal weight and overweight related to BMI. Then, such volunteers were subdivided into other two groups according to values below or above the median of sCD40L.

sCD40L (ρg/mL) concentrations increased in overweight volunteers post-consumption of acai (964 ± 542) compared with the same volunteers pre-consumption of acai (633 ± 187, p = 0.03), and the CCL5 concentrations (ρg/mL) decreased in volunteers with sCD40L concentrations below median after the treatment (4.1 ± 1.5) when compared in same volunteers before the treatment (5.8 ± 1.8, p = 0.02). Protein consumption (g) reduced in volunteers with sCD40L concentrations below median after the intervention (96.6 ± 44.5), when compared before the intervention (96.7 ± 33.8, p = 0.03).

This paper concluded that the acai consumption can modulate the inflammatory profile in both stratified volunteers according to the BMI and the sCD40L marker median.

This study aims to estimate the overall SARS-CoV-2 seroprevalence and evaluate the accuracy of an antibody rapid test compared to a reference serological assay during a COVID-19 outbreak in a prison complex housing over 13,000 prisoners in Brasília.

The authors obtained a randomized, stratified representative sample of each prison unit and conducted a repeated serosurvey among prisoners between June and July 2020, using a lateral-flow immunochromatographic assay (LFIA). Samples were also retested using a chemiluminescence enzyme immunoassay (CLIA) to compare SARS-CoV-2 seroprevalence and 21-days incidence, as well as to estimate the overall infection fatality rate (IFR) and determine the diagnostic accuracy of the LFIA test.

This study identified 485 eligible individuals and enrolled 460 participants. Baseline and 21-days follow-up seroprevalence were estimated at 52.0% (95% CI 44.9–59.0) and 56.7% (95% CI 48.2–65.3) with LFIA; and 80.7% (95% CI 74.1–87.3) and 81.1% (95% CI 74.4–87.8) with CLIA, with an overall IFR of 0.02%. There were 78.2% (95% CI 66.7–89.7) symptomatic individuals among the positive cases. Sensitivity and specificity of LFIA were estimated at 43.4% and 83.3% for IgM; 46.5% and 91.5% for IgG; and 59.1% and 77.3% for combined tests.

The authors found high seroprevalence of anti-SARS-CoV-2 antibodies within the prison complex. The occurrence of asymptomatic infection highlights the importance of periodic mass testing in addition to case-finding of symptomatic individuals; however, the field performance of LFIA tests should be validated. This study recommends that vaccination strategies consider the inclusion of prisoners and prison staff in priority groups.

This paper aims to discuss and collect evidence about the hypothesis that, under imperfect information, the multipurpose public organization emulates its peers, arguing that this hypothesis can be fruitful to the study of this kind of organization.

At IPEC – Instituto de Pesquisa Clínica Evandro Chagas, the clinical research institute affiliated to FIOCRUZ – Fundação Oswaldo Cruz, activities relating to infectious diseases –, e.g. diagnostic exams; outpatient care and patient admissions; teaching and research – are structured in the form of integrated action programs (briefly, PAIs). Taking into account the complexity of this organizational format, this paper applies a mathematical model allowing to define and compute managerial indicators referring to the eight main PAI programs with a view to measure their performance, to investigate whether there are any scale inefficiencies in the eight programs selected as decision‐making units (DMUs) and to assess the effectiveness of the whole organizational structure. To accomplish those objectives, the paper employs the so‐called DEA models with variable returns to scale – whereby two input and seven output variables were used to represent the eight DMUs.

Findings suggest that PAIs related to clinical research operated under increasing returns to scale between 2002 and 2006. To that extent, both the choice of PAIs as an organizational format and the current growth strategy at the Institute may be considered adequate.

This approach is valuable to complement the cost minimization analysis of specific activities of multipurpose organizations and has general application to the overall assessment of performance, structures and strategies in these organizations.

This study aims to expose the main knowledge management (KM) practices applied in BRIC (Brazil, Russia, India and China) industries using scientific literature published in the Scopus database from 2001 to 2010.

A search was performed in papers selected from the Scopus database, which houses the KM practices of industries in BRIC countries.

The results show that Brazil, Russia and India have an easier way of converting tacit knowledge into explicit knowledge compared to China, where informal relationships of trust and friendship play a special role within organizations, as well as where the political structure (communism) is an intervening factor. Brazil, Russia and India practice similar KM mechanisms such as the use of technology, process standardization and electronic data management. They also model the positive experiences of western companies. In China, interpersonal relationships shape the tacit and explicit features of organizations.

The methodological filter could potentially limit the volume of responses, as not every case study can demonstrate the usual practices of KM. Empirical studies are able to capture the nuances and even provide a holistic picture of these practices.

The results have practical implication, in particular. They are expected to help managers and workers to better comprehend KM practices in BRIC countries or even suggest new KM practices in the business.

The main discussion of this paper brings together a large range of KM practices applied in BRIC, addressing similarities and differences between KM deployments.

In developing countries, such as Brazil, the construction sector is consistently focused on the construction of new buildings, and there is no dissemination of the preservation, restoration and maintenance of historic buildings. Idle buildings, due to the use and lack of maintenance, present pathological manifestations, such as moisture problems that compromise specially their thermal and energy performance. With this in mind, the purpose of this work is to create a digital model using terrestrial photogrammetry and suggest retrofit interventions based on computer simulation to improve the thermal and energy performance of a historical building.

The proposed methodology combined terrestrial photogrammetry using common smartphones and commercial software for historical buildings with building information modeling (historic building information modeling (HBIM)) and building energy modeling (BEM). The approach follows five steps: planning, site visit, data processing, data modeling and results. Also, as a case study, the School of Architecture and Urbanism of the Fluminense Federal University, built in 1888, was chosen to validate the approach.

A digital map of pathological manifestations in the HBIM model was developed, and interventions considering the application of expanded polystyrene in the envelope to reduce energy consumption were outlined. From the synergy between HBIM and BEM, it was concluded that the information modeled using photogrammetry was fundamental to create the energy model, and simulations were needed to optimize the possible solutions in terms of energy consumption.

Firstly, the work proposes a reasonable methodology to be applied in development countries without sophisticated technologies, but with acceptable precision for the study purpose. Secondly, the presented study shows that the use of HBIM for energy modeling proved to be useful to simulate possible solutions that optimize the thermal and energy performance.

Technology-based incubators depend on high-level knowledge to constantly meet the demands of the market. Incubators offer a variety of specialized services to help startups increase the chances of crossing the valley of death. These services include infrastructure, access to a professional network of mentors and an intensive support of a consultant team to help with managerial and legal challenges. Therefore, it is critical to incubators to develop both highly skilled teams of consultants and social environment that facilitates communication. The purpose of this paper is to understand how innovation-oriented social networks created within technology-based incubators are shaped.

Data were collected in five incubators participating connected to federal universities from the state of Minas Gerais. The network attributes collected in the survey were placed in a matrix form. The mapping and measurement of the relationships between individuals were developed using the Ucinet software. Ucinet enables the analysis of attributes (attitudes, behaviors and characteristics) characterized as relational (contacts, ties and relationships). The software also includes the Netdraw network visualization tool, which enables the creation of matrices and graphical network maps. The measurements of centrality, closeness and intermediation were analyzed to assess the intra-organizational social network.

The results indicate that although the flow of communication does not follow the formal hierarchy, the interaction between team members to spontaneously exchange ideas, information and experiences is rare. The workers are so concerned about their timely tasks, that they have few opportunities to exchange information and knowledge. The coordination is carried out by university professors, who also perform other tasks (e.g. teaching, research and administration activities) besides those related to the incubators. The results also suggest that in the technology-based incubators studied, besides dealing in an innovative environment, the distribution of tasks and responsibilities are still rigid and traditional.

By analyzing the degree of the relationship between team members, the proximity and the level of intermediation of co-workers, it is possible to see how the incubators workers interact, thereby identifying the flow of information. This study offers implications for theory and practice. To the theory, this study adds to the discussion of intra-organizational social network of technology-based companies in the Brazilian context. To practitioners, this research sheds light on the importance of the social network built within the organization to promote effective communication and knowledge sharing.

An area of information technology (IT) in organizations is required to manage resources efficiently. For this, IT certifications are adopted by companies and sought by professionals. However, these have many requirements and to identify which are paramount to the performance of their activities and/or are much more important to IT managers is not a trivial task. The purpose of this study is to identify how the processes of the Information Technology Infrastructure Library (ITIL) v3 and Control Objectives for Information and Related Technology (CobiT) 5 certifications are analyzed by IT managers. Regarding the knowledge of professionals about the processes, which are more important, less important or indifferent in the manager’s view.

A survey is carried out with IT managers using questions elaborated according to the Kano model in which the processes of the analyzed certifications are related to classify according to the proposed model.

Of the 64 analyzed processes, 20 CobiT processes and 13 ITIL processes were classified as must-be requirements. Another 17 CobiT processes and 9 ITIL processes were classified as one-dimensional and 5 ITIL processes are present in more than one relationship with CobiT processes and, depending on the relationship, they were classified as must-be or one-dimensional requirements.

It is concluded that this study contributes in the discussion of the importance of the ITIL and CobiT implementations and analyzes the relevance of ITIL and CobiT certification processes in the view of IT managers, providing useful information for the professionals in terms of prioritization of the processes expected by the managers.
