title: Legacies of intensive management in forests around pre-columbian and modern settlements in the Madeira-Tapajós interfluve, Amazonia

description: ABSTRACT Amazonian peoples use and manage plant populations in previously domesticated landscapes, but the extent of landscape transformation remains uncertain, especially in interfluvial areas. We tested the hypothesis that useful plant communities vary in richness, abundance and basal area around pre-Columbian and current settlements independent of the distance to a major river. Nine plots were established at different distances from settlements in the Humaitá National Forest and the Jiahui Indigenous Land, where trees and palms with DBH ≥ 10 cm were sampled. Interviews were used to identify species, their uses and management practices. We found high values of richness, abundance and basal area of useful species around settlements both close to and 70 km from the major river. Different use categories presented different responses to current management, which shows that management by current and past populations is selective. We showed that areas of intensive management and landscape transformation are not limited to the margins of major rivers, but also occur in interfluvial areas within a radius of 5 km from pre-Columbian and current settlements. Indigenous people and local communities manage forests around their settlements over time, showing that they are key actors in the sustainable use of Amazonia.

title: Medicinal plants for the "nerves": a review of ethnobotanical studies carried out in South Brazil

description: ABSTRACT Among the medicinal purposes for which plants have been used is the treatment of “nerves". The objective of this study was to search for species of plants used in the state of Rio Grande do Sul (South Brazil) for the relief of symptoms related to central nervous system (CNS) disorders. Twenty-seven ethnobotanical studies were compiled, in which a total of 94 species were cited. The five most cited species were Cymbopogon citratus (81.5 %), Melissa officinalis (77.7 %), Aloysia citriodora (66.6 %), Matricaria chamomilla (62.9 %) and Passiflora edulis (51.8 %). Scientific studies have corroborated the popular use of these plants as sedatives, but most studies are preclinical and very few have been clinical (M. chamomilla and M. officinalis), and these were mainly exploratory or were performed against placebo. In addition to efficacy data, there are also indications of toxicity for M. chamomilla and P. edulis. In conclusion, there is a great diversity of plant species used in the treatment of symptoms related to CNS disorders, and they are most frequently used as a sedative. Data indicate that M. officinalis possesses clinical efficacy in the treatment of symptoms associated with anxiety without signs of toxicity.

title: Forecasting of solid waste generation for the Aparecida de Goiânia (GO), Brazil, landfill by time series

description: ABSTRACT An effective and robust municipal solid-waste-treatment system requires a suitable forecast model to assist in its management. This work was carried out, using time series, an analysis of the projection of solid waste generation in the landfill of Aparecida de Goiânia, located in the State of Goiás. In order to understand the generation of residues, we analyzed the influences exerted by climatic variables and governmental incentives. The model that best fit the studied phenomenon was SARIMA, due to the presence of seasonality in the analyzed time series. As a main result, the forecast for the generation of solid urban waste in Aparecida de Goiânia projected a reduction of the volume produced until 2018. Seasonality in the generation of municipal solid waste does not occur due to the influence of climatic variables. The modeling of municipal solid waste can aid in decision-making and collection management, as well as in contributing to the environmental impacts control.

title: Approach to An Unusual Cardiac Mass: Mitral Annulus Caseoma

description: Abstract Caseous calcification of the mitral annulus (CCMA) is known to be a rare variant of mitral annulus calcification, a chronic and degenerative process of the mitral valve fibrous ring. It usually carries a benign prognosis. The following case demonstrates a huge mitral annulus caseoma that complicated with severe mitral regurgitation and was treated with a successful surgery. The common consensus on the optimal management of CCMA is conservative medical management and avoiding unnecessary surgery. Therewithal, the current indications for surgical intervention include mitral valve dysfunction, strokes and uncertain diagnosis. Aggressive debridement, risk of left ventricular perforation and exposure of caseous debris to the systemic blood flow may increase the risk of a standard mitral valve surgery. Mitral valve replacement should be preferred compared with mitral valve repair.

title: Strategies, Representations, and Flexibility in Multiplicative Comparison Task Resolution

description: Abstract In this article we analyze, based on a theoretical framework on multiplicative comparison, Bruno's conceptual evolution, a student of the 6th grade (11 years), focusing on the adaptive and flexible articulation of concepts, strategies, numerical relations, properties of operations and representations. The way he explores the five tasks proposed in a teaching experiment indicates that the conceptual construction of Bruno's multiplicative comparison lies in the connection between the multiplicative factor and the scalar ratio. His knowledge of numbers and their relationships allows him to use different representations of rational ones in translating the strategies he implements. These vary between additive and multiplicative, and in the latter, the use of the double number line with only two points predominates. The analysis of Bruno's evolution validates and expands the theoretical conceptual framework adopted initially.

title: Mururé (Brosimum acutifolium Huber) in the treatment of syphilis in colonial Amazonia: historical data to the actual contribution to treatment

description: ABSTRACT Historical ethnobotanical studies of medicinal plants reveal important information about traditional practices of human groups and influence current understanding of the use of plants. The present article describes the ethnopharmacology of mururé (Brosimum acutifolium) since the XVIII century for the treatment of syphilis and correlates past and present therapeutic use. This information contributes to the appreciation of historical records in the contemporary use of natural products. The analysis of documental records is important for comparing information available overtime about the medicinal use and application of specific species. The present research was based on the analysis of a Jesuit work and other complementary documents. The medicinal effect of mururé is attributed to its latex, and dosage and adverse reactions are described. Historical documents stand out as valuable assets for pharmaceutical technology because they allow comparisons to be made between past and present uses of species as curative agents.

title: What matters in free listing? A probabilistic interpretation of the salience index

description: ABSTRACT Free listing is a data collection technique used in different subject areas to characterize a given cultural domain. Analysis of a set of lists from a human population allows inferences to be made about the cultural salience of the items in that domain. However, the challenge that the salience index presents is establishing a threshold value for determining whether an item can be considered salient or not. The present analysis reveals how to determine which items of a list have non-randomly determined citation frequency and order. Monte Carlo techniques were used to create a hypothetical null scenario. The present analysis not only objectively identifies which items stand out in relation to the others, it also reveals which items can be considered idiosyncratic and how order and frequency independently influence the salience index. The present analysis represents a useful tool for analyzing data collected through free listing. It also can contribute to understanding processes related to the cultural relevance of items and to the test future hypotheses in different areas of knowledge.

title: THE IMPACTS OF THE NATIONAL PACT FOR LITERACY IN THE RIGHT AGE: A SYSTEMATIC REVIEW

description: ABSTRACT: The article presents the main findings of a systematic review of the National Pact for Literacy in the Right Age (PNAIC), instituted by the Portaria 867, of July 4, 2012, considered the largest teacher training program developed by the Ministry of Education. A typology of the collected works was built - a total of 121 publications - and analysis categories were constructed to evaluate the quality of the evidence produced in the impact assessments (4 studies). The results suggest that: a) there is a large volume of studies on the PNAIC, but a very small number of evaluative studies on the impact of the Program; b) many studies describing potential policy effects are actually about perception of impact; c) the impact studies found, besides being scarce, have low internal and external validity, with important limitations, referring to the design, methodology and scale.

title: OUR NORTH IS THE SOUTH: A CASE STUDY ON THE LATIN AMERICAN DOCTORATE IN EDUCATION AT UFMG

description: ABSTRACT: International cooperation is a strategic component for the constitution and consolidation of stricto sensu excellence postgraduate programs. In the strengthening of the Brazilian Postgraduate System, academic relations with the global North have been valued, where most of the world-class universities are concentrated. This article presents an experience that distances itself from this model, focusing on South-South cooperation and the meanings of regional cooperation to overcome specific problems of Latin America and the Caribbean. The subject of this work is the Latin American Doctorate in Education (DLA) at UFMG/Brazil, which was developed in partnership with Unesco and universities in Chile, Colombia, Ecuador, Honduras, Mexico, Peru and Venezuela. The analysis includes documents of the program and questionnaires answered by graduates. It was concluded that the DLA is an alternative internationalization project, with more autonomy and self-centered, oriented by a social justice conception and solidarity among countries of the region.

title: LONG-TERM RESULTS OF EXTREMITY SOFT TISSUE SARCOMAS LIMB-SPARING SURGERY AND RADIOTHERAPY

description: ABSTRACT Objective: To assess the prognostic factors and results of limb sparing surgery and postoperative radiotherapy (PORT) in patients with non-metastatic soft tissue sarcomas (STS) of the extremities. Methods: Between 1980-2007, 114 extremity-located STS treated with PORT were analyzed retrospectively. Tumors were mostly localized in the lower extremities (71,9%). The median radiotherapy (RT) dose was 60.9 Gy. Chemotherapy was administered to 37.7% of the patients. Tumor sizes were between 3-26 cm (median 7 cm). The three most frequent histological types included undifferentiated pleomorphic sarcoma (26.3%), liposarcoma (25.4%), and synovial sarcoma (13.2%). The median follow-up for all patients was 60 months, and 81 months for survivors. Results: The 5- and 10-year local control (LC) rates were 77% and 70.4%, respectively; actuarial survival rates for 5 and 10 years were 71.8% and 69.1%, respectively. Increasing the dose above 60 Gy for all patients and the patients with positive margins demonstrated a clear benefit on 5-year LC (p=0.03 and p=0.04, respectively). Based on multivariate analysis, the addition of chemotherapy and RT dose were independent prognostic factors for LC. A recurrent presentation significantly affects the disease-free survival. Conclusions: PORT for STS of the extremities provides good long-term disease control with acceptable toxicity in a multidisciplinary approach. Level of evidence III, Retrospective study.

title: Podostemaceae as habitat for macroinvertebrates in streams of Misiones (Argentina)

description: ABSTRACT Podostemaceae are important components of the trophic networks of rheophilic environments but their importance as habitats for invertebrates is little known. In this study, the abundance and taxa richness of macroinvertebrate assemblages associated with Podostemum distichum and Podostemum muelleri (Malpighiales: Podostemaceae) in two low order streams were analyzed across seasons. Mean macroinvertebrate abundance differed significantly among seasons but did not differ between streams. Nine orders of macroinvertebrates were recorded in both streams, comprising 14 families. Non- metric multidimensional scaling (NMDS) reflected some differences in the seasonal pattern, too. The coefficient of similarity and the complementarity indicate that both streams were very similar in terms of the composition of the macroinvertebrate families. The dominant Podostemceae species in each stream constitute intermediate diversity habitats for macroinvertebrates according to the diversity index used.

title: Performance Evaluation of the HadGEM2-ES and Eta Models from Climatic Extremes of Precipitation for the Amazon Basin

description: Abstract The calculation of climate index from observed data and climate models is an efficient way of identifying possible climatic variations on the Amazon basin. Although it is frequent to evaluate the performance of climate models from precipitation and temperature data, the evaluation of their performances using climate index is still little explored, mainly for the Amazon basin. Thus, the present work main objective was to quantify and evaluate the dexterity of the Had- GEM2-ES and Eta models in the representation of eight climate index. The climate index was determined from the daily precipitation from the Climate Prediction Center. To quantify the performance of both models, the bias and mean square error were calculated. These methods were applied on the basis of the annual average of the climate index for the period 1981 to 1990. The results show that the bias of HadGEM2-ES and Eta models is similar in the most climate index. Regarding the mean square error, it was observed that not all climatic extremes indicators based on precipitation data are well represented by both models, but Eta presented better performance in relation to HadGEM2-ES.

title: Dynamic Geometry Contribution in the Introduction to the Perspective Study for High School Students

description: Abstract The objective was to investigate contributions of an interventional proposal using perspective initial ideas for Geometry teaching, in order to expand the repertoire of plane representations and spatial visualization abilities for ten Brazilian High School students. Based on the historical development of techniques for bidimensional representations of spatial figures and methodologically oriented by Design Experiment procedures, activities have been developed in three meetings, at first to analyze paintings and images from various times and, afterwards, using the Dynamic Geometry environment to explore techniques for constructing images in perspective. We sought theoretical support in Parzysz and Gutiérrez's studies on bidimensional representations of spatial figures, particularly on the ideas of "seeing" and "knowing" poles. Qualitative data analysis showed that using a software may provoke interest on geometric constructions and Geometry study, although there were limitations in learning new concepts, especially those based on those participants previous ones. On the other hand, using the software has allowed some participants to become aware of the importance of knowing the representation rules for the interpretation of images in perspective, which shows that a long-term work of this nature can promote learning and visualization in Geometry.
