In this article, a systematic literature review is presented and the Active Methodologies (MAs) used by researchers in findings linked to studies in graduate programs are analyzed, with the aim of investigating the thematic characteristics of academic papers on MAs in mathematics teaching, in the period from 2016 to 2021. This is a study with a qualitative approach. The theoretical support to carry out the review was based on Ramos, Faria and Faria (2014). To facilitate understanding, the studies were delimited into three questions: Which active methodologies are subsidizing the research? In which graduate programs were the research developed? What are the conclusions of these studies? With the systematic literature review, 15 papers were identified, including theses and dissertations from the Brazilian Digital Library of Theses and Dissertations (BDTD), which discussed MAs in Mathematics Teaching. It was observed in most of these papers that Project-Based Learning (PBA) is one of the most used MAs in research and that one graduate program, in particular, stands out, for its important contributions to the quantity and quality of research for mathematics teaching. The results showed that MAs are effective in the teaching and learning process, by developing autonomy and encouraging greater student participation in mathematics classes. [ABSTRACT FROM AUTHOR]

The following paper analyzes prison education studies based on the theoretical reference of Andre et al (1999); Ferreira (2002); Romanowski; Ens (2006). It tries to show the contributions to the debate on educational issues regarding individuals deprived of their liberty. In addition, it highlights the place and the importance that this theme had in that period and the gaps to be filled. Through the bank of thesis and dissertations of the Higher Education Personnel Improvement Department (CAPES), there were identified themes and concerns showed by researchers as well as the theoretical perspectives of such approaches. Meanwhile there was a discussion about the tasks related to education as well as the contributions for its theoretical and practical understanding. As a conclusion, there were 66 (78%) Master's thesis and 19 (22%) dissertations chosen, which means 85 papers written from 1975 to 2012. [ABSTRACT FROM AUTHOR]

This paper presents the study developed to assist Municipal Coordination of Civil Defense and Protection (COMPDEC) of Caxias do Sul in the identification of areas susceptible to flooding events in the municipality. The COMPDEC database from Caxias do Sul, extracted from the Citizen Assistance Service (Alô-Caxias), was used for the mapping of areas with flooding in the city, from 2013 to 2018, which according to the information collected, recorded 317 occurrences in different points of the urban perimeter. Identification of possible areas of flooding was performed using a variation of the Analytic Hierarchy Process (AHP) and Multicriterial Analysis (AM) methods. In order to compare the points with occurrence records, the following data were selected for analysis: hypsometry, slope, hydrography, surface sealing and three-dimensional image generated by the Qgis geoprocessing software, resulting in the identification of 14 areas susceptible to flooding. County. These areas have flatter relief features with slopes less than 25% and surrounded by areas with higher elevations and slopes greater than 50%. The rainfall data analyzed were taken from the National Center for Monitoring and Alerts for Natural Disasters (Cemaden), and indicate that flooding usually occurs after rainfall ranging from 13 mm to 24 mm within 1 hour, or after rainfall with volume from 17 mm to 46 mm over a time period of 2 hours. The validation of the field results indicated that the methodology developed and used in this study was 64% effective, demonstrating the need for adjustments and analysis of other criteria so that it is possible to determine with greater certainty areas with risk of flooding in the urban perimeter of the municipality.

The following paper displays research results that aims to understand how mathematical modeling (MM) is presented in the studies that discuss such topic in Spain. As a methodological approach, the author used the Mapping procedures in Educational Research. The data were gathered from eight papers written by Spanish researchers. They were published in periodicals, in Spanish, in Spain and/or abroad. There were five categories previously established for the analysis: (a) MM theoretical studies; (B) the research context; (C) investigated problems / research interest; (D) methodology; (E) main results and contributions to evolve the specific theme. The study identified theoretical and methodological approaches among the analyzed studies and shows that the core of the research is focused on students and teachers' thoughts, perceptions and actions during the MM process.

This paper aims to analyze in details the discussion about aspects of agrarian question in the North of Rio Grande do Sul in order to contribute to the challenge expressed in the institutional policy of Federal University of Southern Frontier (UFFS) in generating knowledge to change the hegemonic productive matrix and to guide paths that glimpse ecologically engaged ways of produce and live. Therefore, as methodological procedure, we present graphical and cartographic representation of official socioeconomic, and demographic data in order to offer a spatialized reading that allows to readers understand the contradictions of agrarian question in the studied region, as well as presents the positive role of the ONGs acting in the microregion.

The purpose of this research was to identify and analyze the scientific publications, national and international, about the pedagogical strategy of the flipped classroom in the teaching of Mathematics. The study retrieved 16 papers, covering investigations in the contents of Calculus, Numerical Methods and Linear Algebra. Other searches showed the inversion of the classroom in the reduction of anxiety and also in the use of this proposal by teachers of Mathematics. Such mapping indicated a limited number of publications, from 2014 to 2017, with only five journals. Therefore, it is considered necessary new searches that can discuss the flipped classroom and the influences of this one in the teaching of Mathematics. [ABSTRACT FROM AUTHOR]

The field of social machines is still a new area, without a definition that has the common sense of researchers, this creates some difficulties to understand which concept, or which social machine project we should choose. This work aims to investigate in detail the work presented in the social machine workshops and in the main databases, from this analysis we create a study map, a categorization scheme of the works and also graphs of bubbles between the categorizations. It was produced a landscape of the area of social machines, was by identifying the main topics, types, trends and challenges through this preliminary research, as well as defining the maturity of existing contributions. This paper provides a conceptual basis for understanding the area and also detects research problems and gaps in the field of social machines. [ABSTRACT FROM AUTHOR]

This paper presents a reflexive study of the scientific production on Intellectual Capital (IC) from a bibliometric study and from a mapping of the results of research published in Brazilian journals classifi ed as "A" by Capes and in the proceedings of the "EnAnpad" and of the "Congresso USP". The analysis of the 73 papers on CI published between 2000 and 2006 yielded the following results: the greater part of the studies is practical in nature; Mackenzie is the most relevant IES [instituição de ensino superior - graduate studies institution] in terms of scientific production; citation analysis points to the works by Edvinsson and Malone and Sveiby as the most referenced; most of the research devotes attention to external users; 'human, structural and customer capital' is the most used category; Edvinsson and Malone's model inform most of the studies; there is a parallelism between the topics explored in the Brazilian and in the international contexts; the multidisciplinary character of CI research is confirmed, from the tendencies evidenced in the studies.

This paper aims to perform a hydrological modeling and flooding susceptibility spatialization applied to extreme precipitation events in Igrejinha City, RS, for different return periods (RPs). The work included seven stages: i) determination of the rainfall scenarios, ii) calculation of the morphometric parameters, iii) application of a rainfall-runoff model in the basins, iv) applying a hydrological model for the propagation of flows in the main rivers, v) hydrological simulation of extreme events with RP 10, 50 and 100 years, through the combination of the two models used, vi) estimation of reached levels in cross-sections of the river Paranhana, vii) flooding susceptibility spatialization for each RP. It was observed a rapid runoff in small streams that flow into the Paranhana River, which favors the occurrence of flash floods, while in the Paranhana River the runoff time is higher, favoring the development of a gradual flood. In the scenario with 10 years of RP the runoff achieves 1,120 m³/s, while in a rainfall with 100 years of RP, we obtained a value of 2.090 m³/s, representing an increase of 86.6%. However, regarding the area reached by the waters, the difference between scenarios with RPs between 10 and 100 years was only 9.4%. This occurred due to the characteristics of the embedded valley where the city is located, where increase of the flow rate is reflected more in changing river level than the flooded area.

This paper summarizes some findings of a research on typographic elements found in São Paulo city central area. Using mapping methodology, we show that based on the information found in certain inscriptions in the building façades, it is possible to identify patterns and paths of settlement in this area, specially in what regards authorship and dates of design and construction. Although many of the edifices studied are part of the city heritage, heritage files very often lack this kind of information, which can be found in architectonic epigraphs. Defined as signatures, public and everlasting records of design authorship, epigraphs might also be analyzed as an example of visual design applied to the city. [ABSTRACT FROM AUTHOR]
