title: Altmetric studies in Brazil: An analysis from the curricula on the Lattes Platform-CNPq

description: Abstract Field of the information metrics studies with nine years of existence, altmetrics has in Brazil a history three years more recent. If, on the other hand, we consider the field more broadly, such as scientometric studies based on cybermetric or web-based data, we could identify older works. However, delimitation of the field occurred in 2010, when Jason Priem coined the term “altmetrics” via Twitter having arrived in Brazil as “altmetria” in 2013. In the exploratory bibliometric study here presented, we used the Lattes curriculum to identify articles and communications in congresses of researchers, with or without a doctorate degree, who work in the field of altmetrics in Brazil, their large areas and areas of expertise, geographical distribution and the evolution of data and thematic sources over the years. To this end, the identification of curricula was made through the advanced search in the Lattes Platform by the terms “altmetria”, “altmétrico”, “altmétrica”, “altmetric” or “altmetrics”. The 94 curricula found, 37 of which were doctors and 57 of non-doctors, had their contents filtered by the search terms used. Twenty-six articles were identified in periodicals and 36 communications in events. From the 94 researchers it is verified that 53 of them produced only in altmetrics and 41 with intercession with Facebook, Twitter or Mendeley. The field is dominated by researchers from the large area of Applied Social Sciences with emphasis on Information Science and to a lesser extent for Communication. Research focus have been evolving from more theoretical approaches towards practical, evaluative, critical and institutional and regional contexts.

title: Visibility and altmetric impact of the University of Antioquia researchers: Methodology applicable to universities

description: Abstract This work is the result of one of the components of a macro investigation, which seeks to develop a Model to identify the degree of linkage of a university with its environment; in this case, it is applied to the University of Antioquia (Medellín-Colombia). This component refers to the visibility and impact of investigators from the perspective and data off ered by altmetrics. To that eff ect, the altmetrics data of 1,032 investigators from six areas of knowledge are reviewed, taking into account diff erent academic, professional and social platforms, as well as an integrating platform of altmetrics indicators. Although this measurement refers to University of Antioquia investigators, the general methodology for data capture and interpretation may be extended to other universities that share the same investigation and scientific communication, and that from the altmetrics wish to identify the visibility and impact of their investigators and the linking of the institution with its environment, and complement in this way, the traditional bibliometric measurements or other measurements of the university environment, such as the Manual of Valencia

title: Urban governance in Latin America: Bibliometrics applied to the context of smart cities

description: Abstract Society lives in a dynamic, complex, and contradictory urban system that seeks the balance between urban development and environmental preservation. For this purpose, there are Information and Communication Technologies which can make the existence of Smart Cities possible. Thus, developing Smart Cities involves applying inter and multidisciplinary knowledge, which permeates even Information Science. This study analyzes Latin American scientific production by applying Bibliometrics to quantify the publications related to smart cities, geotechnologies, governance, and cadastre. We analyzed scientifi c productionindexed in the Scopus database from 2007 to 2017. We also performed the Factorial Correspondence Analysis for visualization of word clusters in order to verify their co-occurrence in the abstracts of articles. The results identifi ed Brazil as the country with the highest number of published documents. The importance of the term “Smart Cities” was evidenced with the increase of production in the last 5 years, a period that accumulates 98% of such publications. The most common term is “Geographic Information System”, that appears in 75% of the publications. Finally, in the co-occurrence of words, we identifi ed terms that corroborate with the greater objectives of smart cities.

title: Brumadinho disaster: contributions to public policies and sanitation management in emergency periods

description: ABSTRACT This article aimed to analyze the vulnerability of post-disaster sanitation, adopting as a case study the experience of Brumadinho, in the state of Minas Gerais, in January 2019. It was developed from qualitative, descriptive and exploratory research, carried out through documentary analysis and a case study, through the collection of data published on institutional websites. The analysis of the components took place after the critical reading, based on aspects relevant to the approach of the article. After assessing the material collected it was concluded that the lack of urban planning as well as the precarious investment in actions involving basic sanitation and the lack of inspection at the Córrego do Feijão dam were determining factors in the outcome of the disaster. The mining company Vale S.A. did not have an emergency plan, which could assist in the reduction of damages and in making post-disaster decisions. Sanitation measures are essential to prevent the spread of diseases and thus minimize impacts on the affected population. Disasters from mining areas underline the importance of stricter environmental policies that promote healthy and safe environments.

title: Breast cancer diagnosis based on mammary thermography and extreme learning machines

description: Abstract Introduction Breast cancer is the most common cancer in women and one of the major causes of death from cancer among female around the world. The early detection and treatment are the major way to healing. The use of mammary thermography in Mastology is increasing as a complementary imaging technique to early detect lesions. Its use as a screening exam to identify breast disorders has been investigated. The aim of this study is to investigate the behavior of different classification methods while grouping the thermographic images into specific types of lesions. Methods To evaluate our proposal, we built classifiers based on artificial neural networks, decision trees, Bayesian classifiers, and Haralick and Zernike attributes. The image database is composed by thermographic images acquired at the University Hospital of the Federal University of Pernambuco. These images are clinically classified into the classes cyst, malignant and benign. Moments of Zernike and Haralick were used as attributes. Results Extreme Learning Machines (ELM) and Multilayer Perceptron networks (MLP) proved to be quite efficient classifiers for classification of breast lesions in thermographic images. Using 75% of the database for training, the maximum value obtained for accuracy was 73.38%, with a Kappa index of 0.6007. This result indicated to a sensitivity of 78% and specificity of 88%. The overall efficiency of the system was 83%. Conclusion ELM showed to be a promising classifier to be used in the differentiation of breast lesions in thermographic images, due to its low computational cost and robustness.

title: Productive and economic performance of goats of different genetic groups

description: SUMMARY This study aimed to evaluate the bio-economic performance in confinement crossbred goats from different genetic groups. Were used 30 goats, crossbred (F1) intact male, 10 goats Boer x SPRD (undefined breed), 10 x Savannah SPRD and 10 Oberhasli x SPRD, with an average weight of 15 kg and an average age of 100 days. The initial weight was evaluated, final body weight, average daily gain, total weight gain, dry matter intake, water intake, feed conversion and days on feed. As an economic indicator was calculated gross profit margin (MB), the average dry matter intake, the confinement period, the cost of each diet and the cost of vaccines and medicines. We used the 5% Tukey test for comparisons between treatment means. For the variables weight gain, dry matter intake, water intake and body condition score averages observed did not differ between the genetic groups. There was significant effect (P&gt; 0.05) of genetic groups on days on feed. The biological performance of the goats finished in feedlot was not influenced by genetic group. In bioeconomic analysis was no significant difference (P&gt; 0.05) between the evaluated racial groups. Gross profit margin was negative for the mestizos Pardo Alpine x SPRD. The cross between the Boer breed and without defined breed results in premature animals, reaching slaughter weights with reduced confinement period. In the feedlot finishing system crossbred Boer goats x SPRD showed better economic performance, providing greater profitability to the creator.

title: Development of a tool for hydroeletric reservoir operation with multiple uses considering effects of climate changes. Case study of Furnas HPP

description: ABSTRACT The possible impact of climate change on the multiple uses that involve the hydro power plant of Furnas was one of the objectives of this study by proposing a methodological approach to mitigate these conflicts. The first stage of the study was to perform a time trend analysis oh hydrologic variables being identified significant increasing trends in some rain gauges not reflected in streamflow data in the study basin. For representation of the future climate the hydrological model (MGB-IPH) was used inputted by the global model HadCM3 and regional Eta model through the A1B scenario of the IPCC. If the climate changes scenarios are verified, the reservoir can be quickly dumped, however the improvement of a methodology that considers the determination of the length and transgression frequency of levels, conflicts over water use can be minimized without damage to power generation.

title: pH Exudate Test for Determining the Viability of Araucaria angustifolia Seeds

description: ABSTRACTThis study aimed to verify the efficiency of methods of pre-conditioning and periods of water immersion to perform the pH exudate test to evaluate the viability of Araucaria angustifolia seeds. Three pre-conditioning methods (whole seed, seed longitudinally sectioned, excised embryo) and three water imbibition periods (30, 60 and 90 minutes) were tested, and the solution color was evaluated. Additionally, the seeds were artificially aged for four and eight days at 40 °C. The viability was higher in embryos excised, after 30 minutes of imbibition, showing high coefficient of correlation with the germination and tetrazolium tests. Seeds at advanced stage of deterioration should be evaluated by associating the solution color with the tissue aspect. In conclusion, the pH exudate test is efficient to evaluate the viability of A. angustifolia seeds, and it should be performed using excised embryo imbibed in water for 30 minutes.

title: Revisiting the risk concept in Geotechnics: qualitative and quantitative methods

description: Abstract In this paper, the concept of risk is discussed with focus on its use in geotechnics. The authors focalize the operational definition of risk, giving special emphasis to the concept of risk scenarios. Concepts of hazard, vulnerability and susceptibility are focalized because they appear in the literature in place of the concept of risk. Examples are presented. It is concluded that quantitative methods to evaluate risks are associated with non-equations elucidating the cultural, phenomenal and environmental dimensions of the risk concept. Index approach qualitative methods are associated with a compression of risk concept expressed through equations that evaluate risk as a sole number. This apparent paradox in risk analyses - equations associated to qualitative methods - is responsible for most of problems in measuring and communicating risk.

title: Right to the water, right to the city. The universalization of sanitation in precarious urban settlements of Medellin, Colombia

description: Abstract This article analyzes a sanitation universalization program in precarious urban settlements, implemented by the municipal government of Medellin, Colombia. Based on the theory of Political Ecology, it discusses aspects that enable or restrict the expansion of sanitation services to the poor population, and analyzes the experience of Bello Oriente, a settlement not served by the program, where the population, with the support of a local NGO, has managed to improve water supply conditions and mitigate geotechnical risks. The article shows that the solution developed by the community is much closer to a concept of socioenvironmental unit than the municipal urban policy, which proposes a development based on ecological urbanism, but is subject to the neoliberal model of commodification of the city.
