(Universidade Federal de São Carlos, 2021) Amaral, Fatima Beatriz Manieiro do; Simionato, Ana Carolina; Furnival, Ariadne Chloe Mary; https://lattes.cnpq.br/2906322889921375; https://lattes.cnpq.br/9896600626524397; https://lattes.cnpq.br/1291482506649810
As editoras universitárias constituem um campo cultural relacionado à comunicação e divulgação científica. Por meio de discussões da área de Ciência da Informação, com a utilização das Tecnologias da Informação e Comunicação e de metadados, o contexto se torna pauta a fim de que os livros publicados sejam recuperáveis, isto é, encontráveis e acessíveis na Web. Sendo assim, pretende-se elaborar uma discussão sobre os benefícios da adoção de um padrão de metadados por editoras universitárias e a apresentação do ONIX for Books, padrão de metadados editoriais utilizado globalmente. Método: Este trabalho consiste em uma pesquisa exploratória, realizada a partir de um levantamento bibliográfico - com fontes obtidas na busca pelos termos “metadados” e “editoras universitárias brasileiras” no operador Google Acadêmico e na BRAPCI - e documental- com as pesquisas nos websites das editoras universitárias e do padrão ONIX. Resultados: Verificou-se na literatura a importância e benefícios da adoção de um padrão de metadados para a representação de recursos informacionais, com destaque para o ONIX for Books já que é um padrão rico e amplamente adotado nacional e internacionalmente. Conclusão: Para as editoras universitárias, utilizar um padrão de metadados para a descrição de seus livros ou recursos informacionais é urgente, uma vez que garantem a interoperabilidade e recuperação por lojas em plataformas digitais, bibliotecas e bases de dados, chegando mais facilmente ao usuário-cliente final.

(Universidade Federal de São Carlos, 2021) Reis, José Eduardo dos; Sarvo, Denilson de Oliveira; Faria, Leandro Innocentini Lopes de; Amaral, Roniberto Morato do; https://lattes.cnpq.br/3806982041285431; https://lattes.cnpq.br/1542185480817206; https://lattes.cnpq.br/0767710394930118; https://lattes.cnpq.br/6958372164719600
Metric studies on internationalization, especially indicators of co-authorship, present challenges regarding the collection, representativeness, and reliability of the data measuring the impacts of international mobility. Aiming to contribute to the understanding of scientific collaboration initiatives, the present research’s objective was to investigate the relationship between outside teacher education, represented by the completion of a doctoral degree and post-doctoral internship, and international collaboration, identified by the international co-authorships in institutional scientific output. The research method was the exploratory case study, and the case unit was the Federal University of São Carlos. The Lattes Platform and the Web of Science were used as sources of information, and the sample analyzed comprised 12,787 scientific articles and 1,915 Lattes resumés. It was found that 1,850 teachers have doctoral or post-doctoral education (96.6%) and, of these, 632 graduated abroad (33.1%). Regarding the scientific output, 3,487 of the 12,787 articles were published in international co-authorship (27.3%). From the scientific output in international co-authorship, indicators on the groups of teachers with and without education abroad were analyzed. Among the indicators developed, 8.43 articles per teacher were identified for the group with education abroad, while in the group without education abroad, 4.26 articles were identified per teacher. The results demonstrate a positive relationship between doctoral or post-doctoral education abroad with international co-authorships, contributing to institutional internationalization.
As competências apontadas pelo fórum econômico mundial no contexto da indústria 4.0: um levantamento com profissionais da região de Sorocaba – SP
(Universidade Federal de São Carlos, 2021) Fonseca, Juliana Carvalho; Silva, Danielly Cristina Candido da; Ubeda, Cristina Lourenço; https://lattes.cnpq.br/6696784421924024
Industry 4.0 and the advancement of technologies are phenomena that are transforming the work settings of companies, promoting process automation, increased productivity, use of technologies such as big data, machine learning and the internet of things. These changes have a significant impact on work relationships, skills needed by professionals, the disappearance of some occupations and the creation of others. The purpose of this article is to understand whether professionals in the job market understand the skills they need to develop to remain competitive in this new context of the so-called 4th industrial revolution. The research method used is the Survey, and data collection was done through an electronic questionnaire containing multiple-choice and open-ended questions with short answers. The questionnaire was directed to professionals in the labor market who work in the region of São Paulo, Sorocaba and their surroundings. The data were compared with the 15 skills considered essential for the future of work according to the World Economic Forum. After analyzing the results, it is possible to conclude that young workers from the São Paulo - Sorocaba axis understand the importance and master all the competences raised by the World Economic Forum, except for the more technical competences such as use, monitoring and control of technologies, programming , systems analysis and evaluation. This gap raises the need for companies and governments to encourage the development of such technical skills considered important for the future of work. Keywords: Competencies. Industry 4.0. Job market.
The science of racial improvement: historical considerations about Brasilian eugenic education
(Universidade Federal de São Carlos, 2021) Roitberg, Guilherme Prado; Faggion, Melline Ortega; https://lattes.cnpq.br/3993968379492241
Defined by Francis Galton (1822-1911) as the “science of racial improvement”, eugenics became popular among the influential Brazilian intellectual elite in the first decades of the Republic, aiming the biological-racial improvement of the population by combating the “degenerative threats” represented by blacks, mestizos, physically and mentally disabled. Considering this historical context and taking as a theoretical and methodological support a documentary research supported by the critique of instrumental reason, the article analyzes the intellectual production of the directors of the journal Boletim de Eugenia (1929-1933): Renato Kehl, Octavio Domingues and Salvador de Toledo Piza Jr. It is investigated the political-ideological foundations of eugenic education in Brazil and its role in the spread of biological racism among the country's intellectual elite in the 1920s and 1930s. It is concluded that the conception of education of these authors goes beyond the sense of schooling and aligns with a broader intellectual project that envisioned the popularization of the science of racial improvement in Brazil.
A educação eugenista latino-americana: correspondências entre os intelectuais brasileiros e argentinos nas décadas de 1920-1930
(Universidade Federal de São Carlos, 2021) Roitberg, Guilherme Prado; https://lattes.cnpq.br/3993968379492241
A ciência do melhoramento racial ou eugenia foi criada no final do século XIX por Francis Galton. Baseada no determinismo biológico, essa ciência popularizou-se entre a influente elite intelectual latino-americana, levando à criação de organizações comprometidas com o aperfeiçoamento racial da população através do sanitarismo e do combate às ‘ameaças degenerativas’ representadas por negros, mestiços, estrangeiros e deficientes. Amparado pela perspectiva histórica com base na teoria crítica da sociedade, o artigo investiga o projeto utópico-racial do movimento eugenista na América Latina nas décadas de 1920-1930. Por meio de uma pesquisa documental sobre as correspondências e publicações dos eugenistas brasileiros e argentinos, analisamos as vicissitudes do campo intelectual que permitiram o desenvolvimento do racismo biológico latino-americano através da institucionalização da educação eugenista. Dialogando com a bibliografia especializada, demonstramos de que maneira tais documentos consistem em fontes fundamentais na compreensão da conexão Brasil-Argentina vislumbrada pelo movimento eugenista, bem como a permanência dessa rede de apoio intelectual ao longo do século XX.
Brazilian fascism and anti-semitism
(Universidade Federal de São Carlos, 2021) Roitberg, Guilherme Prado; Silva, Mariana Bergo Damaso; Souza, Edson Guilherme de; Gomes, Luiz Roberto; https://lattes.cnpq.br/3993968379492241
O artigo aborda o tema do fascismo na contemporaneidade, a partir dos elementos do antissemitismo descritos por Adorno e Horkheimer em 1947 e por meio das evidências empíricas que marcam atualmente a adesão da sociedade brasileira aos movimentos autoritários e extremistas. A discussão teórica e a análise de situações empíricas nos permitem afirmar que existe um fascismo à brasileira com formas de adesão e expressão bastante peculiares. A questão das fake news é tomada como objeto de análise de um processo que tem sido cada vez mais preocupante, tanto em termos do número significativo de pessoas, que contribuem decisivamente para sua disseminação, como em termos de composição das forças de resistência estabelecidas pela sociedade civil em face do perígo que tais notíciais representam à democracia, à formação da sociedade, ao futuro da humanidade e do planeta como um todo.

Desenvolvimento de livro paradidático para a divulgação científica sobre a biodiversidade de abelhas brasileiras
(Universidade Federal de São Carlos, 2021) Boeing, Guilherme Andrade Neto Schmitz; Abdalla, Fabio Camargo; https://lattes.cnpq.br/7770803221041927; Fernandes, Hylio Laganá; https://lattes.cnpq.br/1315602045624096; https://lattes.cnpq.br/7980973793405832
The use of paradidatic books in science teaching has been shown to be effective in helping students understand and visualize social problems. Currently, Brazil and the world are facing the biggest population decline of angiosperm pollinators thanks to anthropic actions such as deforestation, fires, urbanization, monocultures and pesticides. Thus, the proposal of this studt was to elaborate a paradidatic book on the biodiversity of native bees, in order to use it as material for scientific dissemination. The survey of information and the selection of species for the composition of the book's plot were carried out using the Moure Bee Catalog (http://moure.cria.org.br/index) in conjunction with the Global Biodiversity Information platform Facility (GBIF - https://www.gbif.org/pt/). With the species defined, realistic morphological images were produced using the Adobe Illustrator software, made available by Adobe Systems, and the production of scenarios using the CorelDRAW® Graphics Suite 2020 software. Finally, the Microsoft PowerPoint software was used for the end production of the paradidatic book. After conducting a bibliographic survey of information about native bee species, it was possible to select those that would compose the book based on their biodiversity characteristics. With that, a script was elaborated and, consequently, the scenarios and morphological drawings were produced and finalized. The final layout of the book was carried out and the title “Beeodiversidade” was chosen. With all these processes, it can be concluded that there was a successful development of a paradidatic book for teaching about the biodiversity of Brazilian bees which could expand the reader's knowledge on the subject.
Análise in silico de um novo composto possível inibidor de ciclooxigenase 2 utilizando docking molecular
(Universidade Federal de São Carlos, 2021-01-04) Pedroso, Sofia Dallasta; Schpector, Júlio Zukerman; https://lattes.cnpq.br/4252331837170383; https://lattes.cnpq.br/8054606648208210
This work describes the study of the formation of complexes between the enzyme cyclooxygenase (COX-2) and some of its inhibitors. For this purpose, the known inhibitors celecoxib (CEL), rofecoxib (RCX) and Korean 21 and the ligand RJA4, a potential inhibitor, were evaluated in the studies. The activity of COX-2 can be blocked by non-steroidal anti-inflammatory drugs (NSAIDs) such as CEL, RCX, among others. These drugs are known for their action in reducing inflammatory reactions, pain and fever, as well as their anticoagulatory effect when used in low doses, however, the first side effects detected were kidney failure, and peptic ulcer. The work was carried out using molecular docking simulations evaluating the possible capacity for selective COX-2 inhibition by the RJA4 compound, whose structure is similar to that of other COX-2 inhibiting drugs, generically known as coxibs. For the docking work, the protein with PDB code 5IKR, a crystallographic complex formed by the human COX-2 enzyme and the inhibitor mefenamic acid (ID8), was used. Docking studies were done using the same enzyme cavity occupied by mefenamic acid to position the studied compounds. The evaluation of the docking results was done by graphic analysis, first selecting poses (position, orientation and conformation) of the compounds at the site, and then the interactions between atoms of the ligands and that of the protein amino acids were evaluated: hydrogen bonds, van der Waals interactions and π interactions. It was observed that the π interaction of the ligands with Val523 deserves to be highlighted, a residue related to the specificity for COX-2. To obtain more details on this interaction computational calculations based on electronic density were also performed. The results indicate that the RJA4 compound is positioned similarly to the studied molecules (coxibs, Korean 21, ID8) making similar interactions with the COX-2 enzyme, which suggests that this compound may be a good inhibitor of COX-2. This is the starting point for further studies, whether theoretical, such as molecular dynamics, or in vitro, to experimentally determine the inhibitory potential of the studied molecule.
Produção científica sobre inclusão escolar de alunos com Transtorno do Espectro Autista nas revistas brasileiras de educação especial
(Universidade Federal de São Carlos, 2021-01-05) Santana, Thaluane Sigoli; Postalli, Lidia Maria Marson; https://lattes.cnpq.br/2748282330028870; https://lattes.cnpq.br/0573517603851669
In Brazil, there are two important journals in the Special Education area, the Special Education Journal (REE) edited by the Federal University of Santa Maria, created in 1987; and the Brazilian Journal of Special Education (RBEE), created in 1993, maintained by the Brazilian Association of Special Education Researchers (ABPEE). Both are of extreme relevance for research in the Special Education area, increasing the quantity and qualifying the information about the theme. The present study aimed to perform a bibliographical survey of scholar inclusion of children with Autism Spectrum Disorder (ASD) in the Brazilian Journal of Special Education (RBEE) and Special Education Journal (REE) of Santa Maria published between 2000 and 2020. This research replicated and updated the Cabral and Marin (2017) study. The bibliographical survey utilized the electronic collect data in the Scielo website for RBEE and REE's own website. The evaluated period of RBEE refers to the volumes available online since 2005 in Scielo, and for REE since 2000 available online on the magazine's website. To search for studies, Portuguese words and combined with the Boolean descriptor “and”: Inclusion and School and Autism; Inclusion and School and Autism; School and Autism. A search was also made with the same combinations, but using the expression “autistic spectrum” instead of “autism”. Thirteen scientific research were selected. The studies analyzed were published in 2008 and between 2010 e 2020 (until the data collect, October of 2020), five studies published in RBEE (years 2008, 2010, 2014, 2016, and 2018) and eight studies published in REE (years 2013, 2015, 2017, 2018, 2019 and 2020). Regarding the objectives, four studies investigated the conception of teachers about inclusive education and one of the family members; two studies carried out teacher training; three studies described strategies employed by teachers in working with students with autism, and one article described research on the schooling of people with ASD. Most of the participants were teachers, in total 352, and 25 family members. The number of participants in the studies ranged from one to 217 participants, with three studies had between one and two participants; three studies had between 4 and 12 participants; four studies had between 20 and 58 participants and one study had 217 participants. In general, studies have shown that one of the main factors for inclusion is to rethink the school with different pedagogical attitudes and practices, and also to offer training and specific support to teachers. Future research should invest in evaluating the effects of specific interventions for the development and learning of students with autism.
Comparação entre sistemas de contenção de subsolo: parede diafragma e estacas justapostas
(Universidade Federal de São Carlos, 2021-01-05) Lima, Wilton de Oliveira; Almeida Filho, Fernando Menezes de; https://lattes.cnpq.br/0447825383222965; https://lattes.cnpq.br/8421747725686243
The process of choosing a soil retaining system for underground buildings is based on techniques and economics parameters. There are two very common soil retaining systems in Brazil: Diaphragm Walls and Bored Pile Walls. A bad choosing of that kind of solution can provoke, therefore, building pathology’s and waste. Thereby, the elaboration of a choosing directrix can be very helpful as a source of comparison between these two solutions based on representative technique parameters of the two methods. In this project, the most important technique parameters of the choosing a soil remaining system were studied and, more deeply, the construction processes of Diaphragm Walls and Bored Pile Walls. As result, this study led to the conclusion of a better viability for using Diaphragm Walls when water is present, but specially was observed the importance of knowing and considering all the parameters found.
Do bico à boca: o trabalho itinerante no cultivo de uva em São Miguel Arcanjo, SP
(Universidade Federal de São Carlos, 2021-01-05) Manente, Ingrid Yasmine; Carvalho, Joelson Gonçalves de; https://lattes.cnpq.br/0141039743607067; https://lattes.cnpq.br/7387340401728901
The present monograph deals with the working conditions of the well-known grape workers of the city of São Miguel Arcanjo, a small town in the southwest of São Paulo. The production of grapes in the city is known in the state of São Paulo, and all the São Miguel cultural tradition revolves around the grape, for being one of the main agricultural products produced by the city. In this work, we gave voice to the workers, so that they could report their working conditions, income, and the reasons for becoming cold boiled in the cultivation and thinning of grapes in the city.
Desenvolvimento de Magnésia Cáustica para Revestimento de Aço Elétrico
(Universidade Federal de São Carlos, 2021-01-05) Almeida, Felipe Bento; Pandolfelli, Victor Carlos; https://lattes.cnpq.br/7369376873984839; https://lattes.cnpq.br/8808200197395815
Electric steels are ferrous alloys with up to 3.5 wt.% Silicon in its composition, and with carbon concentrations around 20 ppm. They are materials with excellent magnetic properties, generally used in the manufacture of transformer cores, small and large electric motors and electricity meters. During its processing, electric steel is rolled into slab shape. Then, the material is subjected to a heat treatment in which the carbon inside it, initially at concentrations around 0.2% by mass, is extracted. Also, in this stage, a vitreous silica layer is formed on the surface of the sheets. Then, the material is coated with a suspension of caustic magnesia, and sent to a final annealing, in which the magnesia reacts with the silica layer previously formed, producing a forsterite film on the surface of the steel sheets. This film performs several important functions in the final product. For the formed forsterite film to have the appropriate characteristics for the application, the caustic magnesia used must have a series of properties in specific ranges. In the present work, it was verified what are the properties and the ranges of properties that a caustic magnesia must have to be used in this application. We also sought to produce a caustic magnesia with all these properties from products of the refractory company RHI Magnesita. In addition, we tried to test the developed products in electric steel manufacturers, to verify the possibility of starting a supply of the material to these manufacturers.
Caracterização morfológica do peixe cachimbo Microphis lineatus (Kaup, 1856) na costa brasileira (Teleostei, Syngnathiformes, Syngnathidae)
(Universidade Federal de São Carlos, 2021-01-05) Corazza, Beatriz Martins; Mattox, George Mendes Taliaferro; https://lattes.cnpq.br/4453900943293186; https://lattes.cnpq.br/4115153863565786
Syngnathidae includes seahorses, sea dragons and pipefishes, such as the species Microphis lineatus, which occurs in fresh, estuarine and marine waters off the Atlantic coast, from the USA to Brazil, and Pacific coast of Panama in the canal zone. It presents taxonomic uncertainty and is recognized as a species by some researchers and subspecies by others. Forty years ago, a clinal variation of three meristic data on the Brazilian coast was observed, with counts increasing in the north-south direction. The relatively small amount of material available at the time, however, hindered a better understanding of these clines. This study aimed to morphologically characterize M. lineatus in the Brazilian coast, making it possible to explore such clines with material accumulated in this period, in addition to providing subsidies for a future taxonomic review of the species. Seventeen morphometric and twelve meristic characters were taken from 209 specimens from six Brazilian ichthyological collections. The three characteristics with putative clines were corroborated (number of dorsal-fin rays, total number of subdorsal rings and number of tail rings). The symmetry analysis of the pectoral fins with the counting of their rays showed the absence of bilateral asymmetry in this characteristic. A new southern limit for the distribution of M. lineatus is proposed here: Rio Grande do Sul.
Análise dos determinantes de estrutura de capital das principais empresas do setor de transporte aéreo civil brasileiro
(Universidade Federal de São Carlos, 2021-01-06) Samú, Gustavo Brito; Rossetti, Nara; https://lattes.cnpq.br/4382669390423432; https://lattes.cnpq.br/4382669390423432
There is still no consensus in the financial literature regarding the companies’ capital structure determinants. This discussion has been going on since Durant (1952) proposed the traditional theory - which predicts that there is an ideal configuration of the way companies finance themselves - and was opposed by Modigliani and Miller (1958) - who developed the theory that there is no ideal configuration. Since then, several empirical studies have been developed to test these theses and new ideas have emerged on the subject. However, most of these studies have been carried out in markets quite different from the Brazilian one and, even in these, definitive convictions about the theoretical assumptions of the subject have not yet been defined. This work aims to continue these empirical studies by validating theoretical hypotheses based on data collected from the financial statements of the 3 largest companies in the Brazilian civil air transport sector. For this, using quarterly accounting data extracted from the websites of the companies studied, the statistical technique of multiple linear regression was used, which allowed to evaluate the relationship (positive or negative) between the defined accounting indices and to test the hypotheses raised. The results suggest that the profitability factor is decisive for the companies' capital structure and does not allow us to draw any further conclusions about the others.
Um estudo sobre o perfil do investidor de fundos de investimento imobiliário e a relação entre os indicadores IFIX, IBOV e CDI.
(Universidade Federal de São Carlos, 2021-01-06) Nogueira, Bruna Rocha; Rossetti, Nara; https://lattes.cnpq.br/4382669390423432; https://lattes.cnpq.br/5411858548913736
The present work aims to map the profile of the investor of Real Estate Investment Funds in Brazil, based on the analysis of responses collected in a market survey and also to conclude the list of indicators of the São Paulo Stock Exchange Index (IBOV) and Credit of Interbank Deposit (CDI) before the Real Estate Investment Funds Index (iFIX), using the Multiple Linear Regression algebraic method. In this context, the study proves the greater sensitivity of iFIX linked to the IBOV, characterizing the asset within variable income products, which are adequate and generally present in the portfolio of investors with a moderate profile.
Introdução à geometria diferencial e à análise complexa
(Universidade Federal de São Carlos, 2021-01-06) Silva, Rodrigo Thomaz da; Braun, Francisco; https://lattes.cnpq.br/5890727692959507; https://lattes.cnpq.br/3366281590933587
The paper "Conformal geometry, Euler numbers, and global invertibility in higher dimensions”, by Frederico Xavier, crosses different areas of Mathematics in order to obtain its main result. Among them we have Differential Geometry and Complex Analysis. So, in looking for a better preparation to read the cited paper, this work gathers great part of our study of both areas. We emphasise firstly curves and surfaces, and then complex analytic functions.
