title: ANPAD and the institutionalization process of the Brazilian scientific community on management

description: Abstract A scientific community consists of interaction among people who share values, norms of conduct, common behaviors, that is, institutionalized standards on how to produce and reproduce knowledge and technologies in a given field of knowledge. As a general rule, scientific communities are self-regulating, insofar as their members are organized around associations or societies, which define spaces of action and paradigms on how to undertake science in the field of interest, against a background of certain transverse patterns of conduct applied to different fields of scientific knowledge. This article aims to discuss the role of the Associação Nacional de Pós-Graduação e Pesquisa em Administração (ANPAD) in the activities of scientific publication and regulation of the Brazilian scientific community of administration, and how these activities have contributed to the institutionalization process of this community. This process is analyzed in its historical context, the main achievements of ANPAD are discussed and the main challenges for this community in their consolidation process are stated.

title: Common findings on head computed tomography in neonates with confirmed congenital Zika syndrome

description: Abstract Objective: To describe head computed tomography (CT) findings in neonates with congenital Zika virus infection confirmed in cerebrospinal fluid. Materials and Methods: This was a study of 16 newborn infants who exhibited abnormal head CT findings during an outbreak of Zika virus infection. Those infants had the following features: brain imaging suggestive of congenital infection; brain calcifications and negative results on tests for other main infectious causes of primary microcephaly, namely toxoplasmosis, cytomegalovirus, rubella, and HIV; positivity for Zika virus on IgM antibody capture enzyme-linked immunosorbent assay in cerebrospinal fluid. Results: Decreased brain volume was observed in 13 (81.2%) of the infants. All of the infants showed cortico-subcortical calcifications, mainly located in the frontal lobe. In 15 neonates (93.7%), ventriculomegaly was observed. Colpocephaly was a common finding, being observed in 10 patients (62.5%). A prominent occipital bone was identified in 9 patients (56.2%). Conclusion: Our study proves that Zika virus infection can cause congenital brain damage, with or without microcephaly. Some predominant head CT findings in neonates with congenital Zika virus infection, although not pathognomonic, are strongly suggestive of a pattern.

title: Trophic structure of the fish community throughout the reservoirs and tributaries of the Middle and Lower Tietê River (São Paulo, Brazil)

description: Abstract Aim: We investigated the use of food resources throughout the reservoirs and tributaries of the Middle and Lower Tietê River. Methods The samplings were made in July 2000 (dry period) and January 2001 (rainy period). The fish samples were collected using two batteries of gill nets consisting of 8 nets with 10 meters in length and 1.5 meters wide with different mesh sizes, dip net and dragging nets. The stomach contents were dissected, the portion studied was the stomach and the anterior third of the intestines. Food remains found in the stomach were analyzed under a stereoscopic microscope and its identification was performed to the lowest taxonomic category. Results The analysis of stomach contents returned 30 types of food sources, being 21 autochthonous and 8 allochthonous. Most of the diet of the species in the tributaries consists of terrestrial insects, followed by vegetal material, seeds, crustaceans and mud, whereas in the reservoirs the main diet consists of aquatic insects, vegetal material, seeds and scales. The species of fish analyzed were grouped into 13 trophic categories. In both reservoirs and tributaries, most of the diet was carnivorous, whereas the omnivorous diet occurred only in the reservoirs. Species from rivers are more specialized and in reservoirs they are more generalist, making it a better survival strategy. Conclusions Fishes use the coastal areas of the reservoirs and even of the tributaries to feed on superior plants and insects that have terrestrial and aquatic stages. The trophic characteristics exhibited by the fish in the reservoirs depend on the structuring of the community during the colonization process, the characteristics of each reservoir, the introduction of exotic species of fish and alternative food sources.

title: Digital Soil Mapping Using Machine Learning Algorithms in a Tropical Mountainous Area

description: ABSTRACT: Increasingly, applications of machine learning techniques for digital soil mapping (DSM) are being used for different soil mapping purposes. Considering the variety of models available, it is important to know their performance in relation to soil data and environmental variables involved in soil mapping. This paper investigated the performance of eight machine learning algorithms for soil mapping in a tropical mountainous area of an official rural settlement in the Zona da Mata region in Brazil. Morphometric maps generated from a digital elevation model, together with Landsat-8 satellite imagery, and climatic maps, were among the set of covariates to be selected by the Recursive Feature Elimination algorithm to predict soil types using machine learning algorithms. Mapping performance was assessed using the confusion matrix, and the Z-test among the Kappa indexes of the matrices. In a conventional soil survey, the soils described and classified in the Brazilian System of Soil Classification [Argissolos Vermelho-Amarelos Distróficos – PVAd (Acrisols), Cambissolos Háplicos Tb Distróficos - CXbd (Cambisols), Gleissolos Háplicos Háplicos Tb Distróficos - GXbd (Gleysols), Latossolos Amarelos Distróficos - LAd (Xanthic Ferralsos), Latossolos Vermelho-Amarelos Distróficos - LVAd (Rhodic Ferralsols), and Neossolos Litólicos Distróficos - RLd (Neossols)] were grouped into composite mapping units (MU) using the conventional method. The eight algorithms showed similar performance without statistical difference (Kappa 0.42-0.48). The mapping of soils with varying slopes (LAd, LVAd, CXbd) showed lower accuracy, whereas soils on hydromorphic lowlands (GXbd) were classified more accurately. In map algebra, the result was rather satisfactory, with 63-67 % agreement between the conventional soil map and maps produced by machine learning. The areas with the largest disagreement in the DSM occurred in the LAd unit due to subtle color variation in the Latossolos mantle without a clear relation to any environmental variable, highlighting difficulties in DSM regarding hill slope landforms. Model performance was satisfactory, and good agreement with the conventional soil map demonstrates the importance of the DSM as a potential complementary tool for assisting soil mapping in mountainous areas in Brazil for the purpose of land use planning.

title: Reservoir management: an opinion to how the scientific community can contribute

description: Abstract Aim To report possible academic experiences as strategic contributions to help manage reservoirs ensuring multipurpose uses. Methods In this opinion article, we point out and discuss academic activities that are usually developed to assess environmental studies in reservoirs. Results Experience shows that various contributions can be highlighted in reservoir management, as well as direct contributions for decision-making of the environmental authorities involved, such as: i) development of experimental procedures to solve specific problems; ii) sampling planning activities; iii) analysis, integration and synthesis of data; iv) qualification of human resources, etc. It is important to mention that all academic activities reported in this article are potentially publishable in scientific journals (knowledge areas: environmental management, limnology, sanitation, public health and aquatic ecology). Conclusions According to the related activities, we identified strong academic orientation (water quality determination, greenhouse gas inventories and water quality simulation using mathematical models, aquatic macrophyte decomposition and growth experiments) for reservoir management.

title: Quality of peach fruits Jarillo cv. (Prunus persica L.) in Pamplona, Colombia

description: Abstract The aim of this study was to characterize the quality of peach fruits Jarillo cv., produced under the conditions of altitude tropical climate in three locations: Pamplona, Chitagá and Pamplonita, in Northern Santander, Colombia. Ten trees were sampled by the conditioned latin hypercube method and eight growing fruits with physiological state of maturity were selected. By means of a profile analysis, the hypotheses of parallelism, coincidence and horizontality of quality variables in the complete measurement interval were tested, and in some segments of the interval, some patterns from the graphic point of view were found. A radial diagram was made to study the development of fruit color at each thermal level. When the quotient between longitudinal diameter and equatorial diameter tends to 1 to the left, the highest weight values are reached, highlighting the lowest elevation level, with weights around 150 g. The profile analysis showed, regarding quality variables, that there was a significant interaction between evaluation time and altitude level. The results show that the prevailing climatic conditions affect the physicochemical characteristics of fruits during the growth process until maturation.

title: Bioactive compound retention in frozen red and yellow Strawberry guava pulps added with L-Ascorbic acid

description: Abstract Brazil presents a great variety of native fruits, which have aroused commercial interest, such as the strawberry guava. In this sense, many researches have looked for alternatives that allow postharvest availability of fruits, considering that perishability is a limiting factor for its commercialization. The freezing process is an important alternative in the sense of making these fruits available for longer on the market. The use of L-ascorbic acid is a potent protective agent in the stability of bioactive compounds in fruit pulps. The objective of this study was to evaluate potentially bioactive compounds present in red and yellow strawberry guava pulps added with L-ascorbic acid (1% m / m) and verify its effect on retention of these compounds and in its antioxidant activity during the frozen storage (-20 ± 2ºC). In the pulps were analyzed: antioxidant activity by the capture of the DPPH° and ABTS° radicals, phenols, anthocyanins and total carotenoids. L-ascorbic acid positively influences the retention of bioactive compounds (total phenols, total anthocyanins and total carotenoids) in red and yellow strawberry guava pulps during 120 days of frozen storage (-20 ± 2 ºC).
