Because Pedagogy of the Oppressed has received worldwide acclaim, influenced many, and has uniquely defined Paulo Freire, it is noteworthy to highlight the book’s evolution from concept to publication. What were the contextual factors that prompted Freire to write the book? What was his approach for converting his thoughts to prose? How long did it take him to write the book? To that end, this article examines those and other questions that brought the world Paulo Freire’s seminal text.

The purpose of this paper was to present the stages of the Brazilian startups' organizational life cycle (OLC), identifying and describing the main factors related to the entrepreneurial and organizational perspectives, as well as the factors related to external relationship agents and the associated risks at each OLC stage. In addition, the variables that comprised the three perspectives above were used for a descriptive reading of the evolutionary process from the perspective of intellectual capital during the stages.

The type of research used was quantitative with a descriptive character. For data collection, the authors have used the survey method and two complementary questionnaires were used as research tools. The measurement scale used in these instruments was the 11-point Likert scale. In total, 100 Brazilian startups registered in the STARTUPBASE and residents in São Paulo comprised the sample of this research. For the data processing, it was used the exploratory factor analysis techniques, to identify the analysis factors, and the cluster analysis, to identify the OLC stages.

Based on the results obtained, four stages were identified and described to build the OLC model of this research: Stage I – conception and development; Stage II – organization and traction; Stage III – growth and scale; and Stage IV – consolidation and transition. In addition, the authors described the main lines of evidence found at each stage.

This research contributes to academic studies of the OLC in startups and the evolution of risks that originate from the relationship between external agents in the business environment and startups. Thus, a management map is built, which helps entrepreneurs and managers construct these businesses since such a management map allows identifying the risks and challenges that a startup needs to overcome to grow and develop.

The originality of this research lies in the adaptation of the OLC approach, which is widely used in studies analyzing the growth and development of mature organizations. The authors used this adaptation to analyze the growth and development of startups in Brazil. In addition, the identification and analysis of external agents that make up the business environment, as well as the analysis of the risks, originated from the relationships between the startup and these agents, brought original and essential results and discussions, both for OLC studies and for risk analysis studies in startups.

A sustainable transportation system should represent a win-win situation: minimizing transport's impact on the environment and reducing natural disasters' effects on transportation. A well-distributed set of rain gauges is crucial for monitoring services in smart cities. However, those services should consider the uncertainties about the registers of rainfall impacts. In this paper, the authors present a case study of optimal rain gauge location based on an actual database of rainfall events with impacts on urban mobility in the city of Sao Paulo (Brazil).

This paper presents a maximal covering location formulation and proposes a robustness analysis considering spatial location perturbations.

In this case study, the robustness of the objective function is above 99.99%. The robustness for the number of covered demand points is 88.93%, and the frequency associated with every candidate is between 11.71% and 69.49%.

Incorporating spatial uncertainties on coverage problems is essential to provide stakeholders more realistic supporting tools and to draw different possible scenarios.

The purpose of this study is to address the extended travel time caused by dwelling time at stations for passengers on traditional rail transit lines. To mitigate this issue, the authors propose the “Non-stop” design, which involves trains comprised of modular vehicles that can couple and uncouple from each other during operation, thereby eliminating dwelling time at stations..

The main contributions of this paper are threefold: first, to introduce the concept of non-stop rail transit lines, which, to the best of the authors’ knowledge, has not been researched in the literature; second, to develop a framework for the operation schedule of such a line; and third, the author evaluate the potential of its implementation in terms of total passenger travel time.

The total travel time was reduced by 6% to 32.91%. The results show that the savings were more significant for long commutes and low train occupancy rates.

The non-stop system can improve existing lines without the need for the construction of additional facilities, but it requires technological advances for rolling stock.

To eliminate dwelling time at stations, the authors present the “Non-stop” design, which is based on trains composed of locomotives that couple and uncouple from each other during operation, which to the best of the authors’ knowledge has not been researched in the literature.

This paper contains descriptive discussions of the implementation of strategic planning in a not‐for‐profit (NFP) organization in Brazil, highlighting the factors that engender emergent strategies. This issue requires more study to enrich both the Brazilian literature in particular and the international literature in general in the field of how emergent strategies triggered in NFP organizations.

Reflections on the debate over managerial strategy and implementation are presented. This theoretical basis supports the discussion of a case study of a Brazilian NFP organization. Interviews were conducted with a range of volunteers with the aim of identifying and discussing the implementation changes that were made to previously planned projects.

The main theme emerging from the cases was the lack of commitment of volunteers, which forced change on previously planned projects.

Research that investigates actions that force the managers of NFP organizations to alter their established action plans is not well canvassed in the context of the literature on Brazil. This paper proposes some future research questions in this context.

This paper aims to determine the effects of 11S globulin isolated from Chickpea (Cicer arietinum L.) on lipid metabolism in animals subjected to a hypercholesterolemic and hyperlipidemic diet and compared to the drug simvastatin.

Thirty-six male Wistar rats, kept in individual cages and under appropriate conditions, were separated into groups that were fed a normal diet (STD) containing casein as protein source and according to AIN-93G; a high-cholesterol diet (HC), normal diet plus 1 per cent cholesterol and 0.5 per cent cholic acid and 20 per cent coconut oil; HC diet plus the isolated 11S globulin (300 mg/kg/day); and HC diet plus the simvastatin (50 mg/kg/day), both dissolved in saline and administered by gavage for 28 days. After this time, the animals were killed.

The results indicated that the addition of 1 per cent cholesterol and 0.5 per cent cholic acid induced hypercholesterolemia in the animals without interfering with their weight gain. Analyses of total cholesterol (TC), HDL-cholesterol (HDL-C) and triglycerides (TG) in the plasma, and TC and TG in the liver were made. The results show that the protein isolated from chickpea, and given as a single daily dose, did not affect the levels of plasma TC and its fractions, although decreasing the TG levels. Unlike the simvastatin, the chickpea protein significantly reduced TC and TG in the liver relative to HC group.

A single daily dose of 11S globulin from chickpea contributed as only as additional 2.8 per cent of dietary protein intake. These findings demonstrate that 11S chickpea protein acts as a functional agent in the lipid metabolism in addition to its nutritional properties.

The purpose of this paper is to analyze how, in three different contexts, the National Council for Advertising Self-Regulation narratively uses its past to build an official history concerning its origins that legitimates advertising self-control as a hegemonic narrative.

By using the historical research and the “uses of the past” approach, this study identifies, analyzes and confronts three organizational histories of Conar’s origins (both its official and unofficial versions) in the context of the creation of the Brazilian system of advertising self-regulation.

After a thematic analysis of the documentary sources, the narratives on the National Council for Advertising Self-Regulation’s origins and the self-control process were grouped into three versions: the narrative under the military regime: 1976/1980; the narrative during the process of re-democratization of the country: 1981/1991 and the contemporary narrative: from 2005 onwards. These narratives were confronted and, in consequence, provided, each of them, a different interpretation of the context surrounding the creation and justification for advertising self-control.

The study shows how a consumer defense organization re-historicized its past strategically to gain legitimacy in three different ways through time. It also reveals that organizations strategically use their past to build an intended vision of the future, thus having more agency than the hegemonic literature in management studies usually guarantees. Finally, it exposes the malleability of past narratives through which organizations play a critical role in the ongoing struggle for competing uses of the past. Therefore, the study identifies different organizational stories through time that allow researchers to reflect on several strategic uses of the past by organizations.

Today, organizations must be able to create innovative strategies, and creative performance depends on knowing what hinders or stimulates creativity. This paper aims to determine which factors in the workplace environment positively or negatively affect creativity by analyzing individuals’ perceptions in a sample of Brazilian industrial companies.

The discussion is based on the componential theory of creativity and the use of a recognized research instrument (KEYS). A regression analysis was carried out, using eight environmental factors related to creativity. The purpose of the collection is to observe the statistical relationships between the scales of the factors and the results related to creativity.

Among the eight factors of the original componential theory, only three were found to have a significant impact on the creative process: organizational incentives, challenging work and support from the work group.

The sample in this study was relatively small, and a larger sample will be required to undertake factor analysis.

Possible implications for the management of innovation in the Brazilian context are discussed in light of these results.

This study contributed to the production of knowledge, still scarce in the country, about the search for creative solutions through the work environment by confirming which factors are significant and determinants of creative performance and challenging factors that had already been proven by other studies in non-Brazilian contexts.

In this paper a model for the prediction of the failure strain of fiber reinforced polymer (FRP) sheets is proposed, based on a significant database consisting of results reported in the literature for concrete columns with circular cross-section confined with carbon, glass and aramid fiber reinforced polymers. This study aims to analyze the aforementioned model.

Significant experimental research on the confinement of columns externally wrapped with FRP has been carried out in the last decades. Several models of confined concrete have been proposed using different approaches for the prediction of the failure strain of FRP sheets. The majority of those proposals were developed to be simple, thus significant differences with experimental results can be found.

The results of a total of 572 specimens were considered. Statistical analysis was used to derive a regression model, which relates the outcome to a set of predictors of interest using linear assumptions.

The proposed model is shown to be more accurate than other proposals found in the literature.

This paper aims to investigate Lean Six Sigma (LSS) in the Brazilian context, seeking to identify its main characteristics and opportunities for future research.

This study focuses on a literature review in the area of production engineering and operations management, where 104 relevant scientific publications were identified.

The results show that the most important critical success factor for integrating LSS in Brazil is top management support and commitment. LSS integration occurs predominantly in large industrial companies, being incipient in small and medium-sized enterprises. In general, there is no structured way of applying LSS. A standard framework for LSS is still lacking.

This study is limited to a sample that only comprises Brazilian scientific studies.

Professionals and practitioners can understand the evolution of LSS through practical applications and the main LSS tools used in both the industrial and services sectors. It also points out the critical success factor for the implementation of LSS. The study highlights several roadmaps for LSS implementation adopted by large and modern Brazilian automotive industries based on a robust technological base. This study also contributes to expanding the evidence base of LSS application, both in Brazil and in other countries.

Some suggestions are proposed to clarify the structure and complexity of integrated implementation of LP and SS as well as expand the LSS application in small and medium-sized enterprises. This study is the first to discuss the current situation of LSS in Brazil and provide suggestions to expand LSS in the country. Comparisons of Brazilian LSS literature review with researches of others countries are also presented.
