Metodologias para alocação equitativa de recursos financeiros em saúde: uma revisão integrativa
Authors: Carnut Leonardo , Mendes Áquilas , Leite Marcel Guedes
Published: November 2020

RESUMO Há diversas experiências no mundo que visam ao desenvolvimento de metodologias para alocação de recursos para a saúde, contudo, o que resta saber é até que ponto a equidade é operacionalizada nesses métodos. Por isso, este estudo objetivou analisar o que tem sido produzido nas literaturas nacional e internacional a respeito das metodologias de alocação equitativas de recursos em saúde e suas dimensões. Realizou-se uma revisão integrativa em três portais/bases de dados (Bireme, PubMed e Scopus) de artigos científicos, publicados em português, inglês e espanhol. Foram identificados nos artigos o(s) objetivo(s), o método do estudo utilizado pelos pesquisadores e a abordagem sobre a metodologia de alocação de recursos em saúde no que se refere à discussão/operacionalização da equidade. Ainda são poucos os estudos em que alocação equitativa é tema central. Há certa imprecisão sobre a delimitação entre ‘alocar’ e ‘financiar’. Em geral, as metodologias precisam admitir as implicações (bio)éticas relativas à equidade, devem se basear minimamente na dimensão per capita, em conjunto, compulsoriamente, com a orçamentação incremental, com as questões sociodemográficas, sociossanitárias e epidemiológicas e ter centralidade na ‘necessidade de saúde’, sendo necessário um constante aperfeiçoamento da metodologia ao longo do tempo para refinar a operacionalidade da equidade.
Alternative to Tukey test
Authors: Batista Ben Dêivide de Oliveira , Ferreira Daniel Furtado
Published: November 2020

ABSTRACT In order to search for an ideal test for multiple comparison procedures, this study aimed to develop two tests, similar to the Tukey and SNK tests, based on the distribution of the externally studentized amplitude. The test names are Tukey Midrange (TM) and SNK Midrange (SNKM). The tests were evaluated based on the experimentwise error rate and power, using Monte Carlo simulation. The results showed that the TM test could be an alternative to the Tukey test, since it presented superior performances in some simulated scenarios. On the other hand, the SNKM test performed less than the SNK test.

Published: November 2020

ABSTRACT Methionine is an essential amino acid, and generally, the first limiting one in the diets of tambaqui, the main native fish produced in continental aquaculture in South America. However, there is a lack of information on their amino acid requirement, especially for maintenance and efficiency of utilization. The present study aimed to determine the requirement of [methionine plus cystine] for the maintenance and efficiency of utilization using tambaqui of different body weights. Two experiments were carried out using 250 tambaqui with weights of 100 and 300 g. They were distributed in a completely randomized design with four treatment groups (0.264, 0.396, 0.528, and 0.660% of digestible [Met + Cys]), five replications. The control treatment (CT) was performed with the addition of methionine at the first level (0.264%) until the second level was reached (0.396%). The maintenance requirement was determined by the regression analysis between the consumption of [Met + Cys] and protein retention equal to zero. The efficiency was determined using the value of the slope coefficient of the line obtained by the linear regression. The protein and methionine retention values of tambaqui weighing 100 to 300 g were compared by the parallelism test, and no difference was observed between the parameters of the equations indicating the need for only one equation to describe the responses to body weights. The requirement of digestible [Met + Cys] for the maintenance of tambaqui with weights from 100 to 300 g was 60.47 mg kg-0.7 day-1 and the efficiency of utilization of 42%.

Published: November 2020

ABSTRACT The present study evaluated the physiological and biochemical parameters of apple trees under different irrigation water depths in a semiarid region of Brazil. The experiment had a split-plot randomized block design. Irrigation levels (60, 80, 100, and 120% of the reference evapotranspiration - ET0) and two apple cultivars (Julieta and Princesa) were analysed in the experimental plots and the phenological stages (vegetative, flowering and fruiting) were analysed in the experimental subplots. The physiological characteristics evaluated included the chlorophyll index, relative water content, net photosynthesis, stomatal conductance, transpiration, internal CO2 concentration, leaf temperature and instant carboxylation efficiency. The biochemical characteristics evaluated included the leaf contents of reducing sugars, total soluble sugars, and non-reducing sugars and proteins. The best biochemical responses were observed in the Princesa cultivar under 80% ET0 during the flowering and vegetative stages and under 120% ET0 during the fruiting stage. The best physiological responses for all phenological stages were observed under irrigation levels of 120% ET0 for both cultivars. The cv. Princesa demonstrated osmotic adjustment under water stress conditions during the phenological stages evaluated.

Published: November 2020

ABSTRACT Campomanesia rufa (O. Berg) Nied. is a native Cerrado species that presents great edible potential. However, it is a species “in danger of extinction” as recommended by the International Union for the Conservation of Nature (IUCN). No technical and scientific information about the species exists, thus demonstrating the importance of its research. The present work aimed at the physical and chemical characterization of immature and mature C. rufa fruits. The fruits showed a change in coloration from green (b * = 25.11, h = 122.43) to yellowish-green (b * = 34.26 , h = 115.73), an increase in mass (6.54 g to 10.88 g), diameter (23.76 mm to 28.03 mm) and soluble solids (8.00 to 10.80%). The fruits presented high levels of total (1246.35 mg 100 g-1) and soluble pectin (195.93 mg 100 g-1), high water content (78.86 g 100 g-1), low pH value (3.40), and high citric acid content (1.2%). However, the fruits had low protein (0.81 g 100 g-1), lipid contents, and low caloric values (64.76 kcal 100 g-1). The fruits presented significant values of carotenoids, phenolic compounds (312.47 mg 100 g-1), vitamin C (263.60 mg 100 g-1) as well as good in vitro antioxidant activity (1862.81 µM g-1). The results obtained indicate that C. rufa fruits showed a similar composition to the fruits of other Campomanesia species, and their biological properties should be investigated additionally under in vivo conditions.

Published: November 2020

Resumo O cenário atual do trauma por causas violentas tem apresentado um elevado número de casos. Entre eles, a lesão de aorta torácica por trauma penetrante é uma condição de elevada morbimortalidade que exige diagnóstico adequado e que, nos últimos anos, tem sido corrigida com procedimentos endovasculares. Essa modalidade de tratamento se mostra mais segura, com menor número de complicações em relação ao procedimento cirúrgico aberto. Após a realização da abordagem endovascular, há necessidade de acompanhamento contínuo, que visa monitorar as condições de saúde do paciente e corrigir possíveis complicações relacionadas ao procedimento. O objetivo deste artigo é relatar um caso de traumatismo penetrante de aorta torácica, tratado por via endovascular, visto que a literatura aborda predominantemente as lesões por trauma contuso.
Pastoreio, governo e os limites do entendimento: sobre a condição ética dos cães no sertão cearense
Authors: Teixeira Jorge Luan
Published: November 2020

Resumo O artigo discute a condição ética dos cães nos sertões cearenses tomando como foco de atenção os ataques de alguns deles aos rebanhos ovinos. Geralmente levando à morte dos cães, tais episódios produzem uma espécie de curto-circuito moral nas concepções sertanejas sobre os cristãos (humanos) e os brutos (animais) e problematizam a inocência conferida a priori aos segundos. Se os conceitos de pastoreio e governo chamam a atenção para o dever humano de cuidar dos animais de criação e de se responsabilizar pelas suas ações, eles também evidenciam que, para os sertanejos, animais como os cães são capazes de agir e de pensar eticamente. Longe de serem concebidos apenas como seres com “significado ético” para os humanos, os cães são percebidos na vida ordinária como “sujeitos éticos”. Este trabalho, portanto, precisa a especificidade dessa condição ética em face daquela dos humanos e argumenta que ambas estão entrelaçadas.
Sacerdotisas africanas no mundo bíblico. Leitura decolonial de Êxodo 4.24-26
Authors: Caldeira Cleusa , Artuso Vicente
Published: November 2020

Resumo: Da experiência espiritual da mulher negra em diáspora, surge um pensamento fronteiriço como resposta bíblico-teológica à experiência histórica do racismo. Trata-se de um exercício hermenêutico que assume o imperativo ético e epistemológico da decolonização da teologia e da Bíblia, visto que ambas serviram como “ferro em brasa” para subjugar e desumanizar os povos de origem africana. De um exercício interpretativo a partir do subalterno, desvela-se o protagonismo espiritual da mulher negra no mundo bíblico a fim de revelar as matrizes africanas da fé judaico-cristã. Com isso, anseia-se contribuir para a desconstrução do imaginário eurocêntrico que segue legitimando a dominação e o aniquilamento do outro e, assim, cooperar para a reconstrução de um imaginário despatriarcalizado e antirracista.
Ficções porno-políticas do corpo (a partir) de Preciado
Authors: Oliveira Ana
Published: November 2020

Resumo: Partindo dos escritos de Preciado, este artigo propõe uma problematização contradisciplinar das representações do corpo enquanto produto epistemológico e enquanto laboratório político. A primeira parte, dedicada ao tópico central do Manifesto contrassexual (plasticidade dos sexos e sexos de plástico), discute o sentido de Natureza e a ruptura epistemológica com o discurso sobre uma ordem natural que precede e constitui o humano. A segunda parte centra-se nas noções do corpo como laboratório, introduzidas em Testo yonki. Combinando ficção autopolítica, autoteoria e ensaio corporal, Testo yonki relata um protocolo de intoxicação voluntária à base de testosterona sintética. Essa experimentação corporal, que permite a Preciado ficcionar-se como hacker-sexual ou pirata-do-sexo, apresenta-se como um meio de renovação do sentido de si. No seu conjunto, este artigo pretende contribuir para uma análise preciadista de Preciado, isto é, uma análise do sujeito (biografia) que é feita a partir das próprias categorias criadas pelo autor (bibliografia), fazendo de Preciado simultaneamente fonte e objeto de teorização. Trata-se, desse modo, de um ensaio biópico, no qual procuro explorar e combinar as dimensões de produção biográfica e bibliográfica de Preciado.
Analysis of the level of disclosure of the mission statements of large Brazilian companies,
Authors: Junqueira Emanuel , Camacho Reinaldo , Santos Eric Ferreira dos
Published: November 2020

ABSTRACT The aim of this study was to verify the level of disclosure of the survival, growth, and profitability (SGP) construct in the mission statements of Brazilian companies and in the collective discourse of different economic sectors, classified according to the “Biggest & Best” Annual published by Exame Magazine. The research seeks to fill the gap in the field by studying the disclosure of the SGP construct in the mission statements of large Brazilian companies. Considering the mission statement as the genesis of strategic planning, an analysis of the disclosure of the SGP construct allows for a discussion of the relevance of the contribution of the mission statement to the elaboration, implementation, and monitoring of that planning. The benefit of a mission statement aligned with the strategic planning lies in adequate communication to the stakeholders regarding the long-term SGP goals, based on the assumption that comprehensive and objective communication minimizes the risks of failures during the management process. Collective subject discourse (CSD) was used to develop a qualification metric of the constitutive elements of the organizational mission statements, enabling it to be identified whether the Brazilian companies, grouped into different economic sectors, are smoothing, concealing, or omitting the construct formed by the SGP components in their mission statements. This study investigates the presence or not of the SGP components in the collective discourse of mission statements of 220 large Brazilian companies. Most of the companies analyzed in the sample do not include SGP in their mission statements and those that do discuss it with discursive vagueness, lacking clarity in their disclosure of the components. For the academia, this finding contributes to understanding the constituent components of the mission statements of large Brazilian companies. For organizations, the findings indicate the need to reflect on the content to be used in the formulation of their mission statements.
Relationship between market discipline and capital buffers in Brazilian banks,
Authors: Carvalho José Alves de , Dantas José Alves
Published: November 2020

ABSTRACT The aim of this study was to investigate the relationship between the market discipline and the capital buffers of Brazilian banks, identifying the channels through which this phenomenon materializes. The literature on market discipline and capital buffers has focused on developed countries. In Brazil, the topic is in its infancy, despite the characteristics of the market representing a relevant opportunity for broadening the related studies. Even with the specificities of an emerging market, the Brazilian banking industry provides a vast field for studying market discipline and capital buffers, given that the banks have leverage with investors, who are sensitive agents to alterations in the risk appetite of those entities. This study contributes to understanding the dynamics of the market discipline in the banking industry and to fostering discussions about the role of that private supervision in promoting the transparency and solidity of the financial system, providing support and guidelines for banking regulation. Using data from 193 Brazilian banks, from 2001 to 2017, the empirical tests included the estimation of panel data models, with the use of two-stage least squares (TSLS), following Ayuso et al. (2004), Flannery and Rangan (2004), and Nier and Baumann (2006). As the discipline exercised by the monitoring and influence of the market is not directly verifiable by external agents, six proxies were developed based on the cost of fundraising, on unsecured deposits, on subordinated debt, and on disclosure. The capital buffer was represented by the difference between the capital calculated by the institution and the minimum regulatory requirement. The results of the empirical tests revealed a positive association between the capital buffer and market discipline, providing evidence of the presence of that private supervision in the Brazilian banking industry.

Published: November 2020

RESUMO O controle biológico no Brasil vem crescendo devido aos problemas gerados pelo uso indiscriminado de inseticidas químicos. A Musca domestica representa o maior problema em granjas avícolas devido às condições favoráveis para seu crescimento populacional. Sendo assim, foram realizadas capturas de dípteros muscoides em um aviário na região de Montes Claros, MG, usando armadilhas contendo isca química e captura por busca direta e, destas moscas, foram isolados e identificados fungos residentes nestes insetos. Os fungos isolados foram duas espécies do gênero Aspergillus sp., um do gênero Memnoniella sp., Scopulariopsis sp., Paecilomyces sp e um fungo da família Moniliaceae. Foram também requeridos junto ao CENARGEM/EMBRAPA as espécies de fungos entomopatogênicos Beauveria bassiana CG 470 e CG 472; Metarhizium anisopliae CG 34 e CG 312 e o Paecilomyces sp. CG 301. As espécies selecionadas para os bioensaios foram um Aspergillus sp., Memnoniella sp. e os Metarhizium anisopliae CG 34 e CG 312 por terem boa esporulação. Os fungos Aspergillus sp. e o Memnoniella sp. não apresentaram capacidade entomopatogênica, os fungos M. anisopliae CG 34 e CG 312 foram bastante eficientes em controlar a emergência dos adultos de M. domestica, mostrando-se bons agentes de controle biológico.
The Validity Concept in Medical Education: a Bibliometric Analysis
Authors: Souza Ruy Guilherme Silveira de , Sequeira Bianca Jorge , Martins Antonio Carlos Sansevero , Bicudo Angélica Maria
Published: November 2020

Abstract: Introduction: Assessment is a critical part of learning and validity is arguably its most important aspect. However, different views and beliefs led to a fragmented conception of the validity meaning, with an excessive focus on psychometric methods and scores, neglecting the consequences and utility of the test. The last decades witnessed the creation of a significant number of tests to assess different aspects of the medical profession formation, but researchers frequently limit their conclusions to the consistency of their measurements, without any further analysis on the educational and social impacts of the test. The objective of this work is to determine the predominant concept of validity in medical education assessment studies. Method: The authors conducted a bibliometric research of the literature about studies on the assessment of learning of medical students, to determine the prevalent concept of validity. The research covered a period from January 2001 to august 2019. The studies were classified in two categories based on their approach to validity: (1)” fragmented validity concept” and (2)” unified validity concept”. To help with validity arguments, the studies were also classified based on Miller’s framework for clinical assessment. Results: From an initial search resulting in 2823 studies, 716 studies were selected based on the eligibility criteria, and from the selected list, of which 693 (96,7%) were considered studies of the fragmented validity concept, which prioritized score results over an analysis of the test's utility, and only 23 studies (3,2%) were aligned with a unified view of validity, showing an explicit analysis of the consequences and utility of the test. Although the last decade witnessed a significant increase in the number of assessment studies, this increase was not followed by a significant change in the validity concept. Conclusions: This bibliometric analysis demonstrated that assessment studies in medical education still have a fragmented concept of validity, restricted to psychometric methods and scores. The vast majority of studies are not committed to the analysis about the utility and educational impact of an assessment policy. This restrictive view can lead to the waste of valuable time and resources related to assessment methods without significant educational consequences.

Resumo: Introdução: O programa de extensão Amigos do Sorriso foi construído a partir da compreensão da extensão universitária como integrante da formação dos estudantes, ao proporcionar vivências e trocas na aproximação entre a academia e a sociedade em geral. Os participantes são estudantes da área da saúde e desenvolvem atividades lúdicas com foco no processo de humanização, na educação em saúde e nos seus efeitos multiplicadores. Desde 2010, o programa realiza atividades quinzenais numa instituição de longa permanência para idosos (Ilpi), com o objetivo de oportunizar momentos lúdicos, com estratégias criativas e comunicativas, no sentido de ressignificar a velhice por meio do brincar. Este artigo tem como objetivos descrever as vivências e compreender quais foram os aprendizados desenvolvidos pelos estudantes de Medicina nesse âmbito. Método: Trata-se de uma pesquisa qualitativa, desenvolvida a partir de 13 narrativas redigidas entre 2018 e 2019 por estudantes de Medicina que participaram das atividades lúdicas na Ilpi. Realizou-se análise temática de conteúdo dos materiais em diálogo com os referenciais teóricos e a literatura relacionada. Resultados: As três categorias temáticas foram: o brincar com o idoso, construção artesanal da comunicação e partilha entre gerações sobre o envelhecer. Os extensionistas discutiram as diversas formas do brincar, sua relação com a promoção da saúde e as especificidades de desenvolver atividades lúdicas com o idoso. Utilizaram diversas formas de comunicação para interação com os idosos, conversando, ouvindo e contando histórias e respeitando os silêncios, o que provocou encontros e desencontros, todos disparados pelo brincar. Discutiram sobre o processo de envelhecimento, a saúde do idoso, a velhice asilar e o próprio encontro de gerações por meio do qual puderam refletir sobre si mesmos. Conclusões: As atividades na Ilpi proporcionaram aos estudantes a percepção da potência das estratégias lúdicas, promotoras da autonomia e saúde, sem infantilização dos idosos. Possibilitaram o reconhecimento de estratégias para aproximação e vínculo, respeitando limites individuais e coletivos, ao compartilharem histórias e sentimentos de forma empática. Dessa forma, destaca-se o desenvolvimento de competências para o futuro médico, tanto gerais como para o cuidado com as pessoas idosas, no reconhecimento de que todos estão envolvidos no universo do florescer do envelhecimento.
The relationship between periodontite and diabetes mellitus type ii facing the new classification of periodontal diseases: literature review
Authors: OLIVEIRA Lívia Maria Lopes de , BARBOSA Lívia Mirelle
Published: November 2020

ABSTRACT Periodontal disease and type 2 diabetes mellitus are considered chronic diseases that at their core have a deep relationship with inflammation. It is assumed that there is a bidirectional relationship between periodontal disease and type 2 diabetes mellitus. It is estimated that approximately 10% of the world’s population is affected by periodontal disease, in its most severe form, almost the same percentage estimated for people with diabetes, which is considered a 21st century emergency. The World Workshop for the Classification of Periodontal and Peri-implant Diseases and Conditions took place from September 9-11, 2017. The aim of this study is to analyze the results of this workshop with regard to the relationship between periodontal diseases/conditions and diabetes mellitus, in addition to conducting an integrative review on the topic. A literature review was conducted, using the Medline electronic databases via Pubmed, Scientific Electronic Library Online, Scientific and Technical Literature of Latin America and the Caribbean and Virtual Health Library. A new classification of periodontal disease included tools for individual assessment of the patient and recognizing risk factors that might negatively interfere in response to treatment. The occurrence of metabolic lack of control in periodontal patients with type 2 diabetes mellitus is now considered a factor of great importance for the assessment of individual susceptibility to the progression of periodontitis. Diabetes is believed to promote a hyper inflammatory response to bacterial challenge by modifying the tissue response of periodontal tissues.

Published: November 2020

ABSTRACT Objective: To present the current evidence on clinical and laboratory characteristics of infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during childhood and adolescence. Data source: This is a narrative review conducted in the databases: Medical Literature Analysis and Retrieval System Online (MEDLINE/PubMed), Latin American and Caribbean Health Sciences Literature in the Virtual Health Library (LILACS/VHL), Scopus, Web of Science, Cochrane Library, portal of the Coordination for the Improvement of Higher Education Personnel (Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES), Scientific Electronic Library Online (SciELO), ScienceDirect, and Cumulative Index to Nursing and Allied Health Literature (CINAHL). The terms used were SARS-CoV-2, COVID-19, novel coronavirus, child, newborn, and adolescent. Data synthesis: Unlike adults, most children infected by SARS-CoV-2 have mild or asymptomatic clinical presentations. Symptomatic children mainly have low fever and cough, with some associated gastrointestinal symptoms. Severe cases are rare and occur especially in infants under one year of age. Detection of viral particles in feces seems to be more persistent in children and can be used as a tool for diagnosis and control of the quarantine period. Different from adults, children can present distinct inflammatory responses, as has happened in new cases of Kawasaki-like syndrome associated with SARS-CoV-2 infection. Conclusions: Most children have asymptomatic or mild presentations, with a prevalence of fever, cough, and gastrointestinal symptoms. New cases with different systemic inflammatory reactions in children have been reported, with clinical manifestations distinct from those typically found in adults.

Resumo A determinação da área foliar é de fundamental importância em estudos ecofisiológicos que buscam entender a relação planta-ambiente. Objetivou-se com esta pesquisa determinar uma equação alométrica que permita estimar a área foliar de Mesosphaerum suaveolens a partir de medidas lineares do limbo foliar (comprimento e/ou largura). Coletaram-se 900 limbos foliares aleatórios de diferentes formas e tamanhos, em uma área de Caatinga antropizada, localizada no município de Santa Luzia, estado da Paraíba, nordeste do Brasil. Para a construção das equações alométricas utilizaram-se os seguintes modelos de regressão: linear, linear sem intercepto, quadrático, cúbico, potência e exponencial. O modelo linear sem intercepto utilizando o produto entre comprimento e largura (C.L) foi o mais indicado para estimar a área foliar de M. suaveolens, com maior coeficiente de determinação (R2) e índice de concordância de Willmott (d), menor erro absoluto médio (MAE), critério de informação de Akaike (AIC) e raiz do quadrado médio do erro (RQME), e índice BIAS mais próximo de zero (R2 = 0,9971; d = 0,9989; MAE = 0,422; AIC = 2094,69; RQME = 0,770; BIAS = -0,0105). A área foliar de M. suaveolens pode ser estimada satisfatoriamente pela equação AF = 0,6787*(C.L).

RESUMO Objetivo Examinar e mapear as evidências científicas acerca das percepções das mulheres em situação de violência quanto aos serviços de apoio social formal. Método Scoping Review, conforme Joanna Briggs Institute e a questão norteadora: “Qual a percepção das mulheres em situação de violência ao buscar atendimento profissional nos serviços de apoio?”. Inclusos estudos nacionais, internacionais, primários, abordagens qualitativas, quantitativas, métodos mistos, idiomas inglês, português e espanhol, no espaço temporal de 2014 a 2019. Realizadas buscas em sete bases de dados, encontrados 1557 artigos e selecionados 16 como amostra final. Resultados Os atendimentos evidenciaram a escuta ativa, criação de vínculo e articulação dos serviços. Como também a falta de acolhimento; sentimento de insegurança, medo e humilhação. O processo de capacitação foi estabelecido pelos artigos como ferramenta aos profissionais, na promoção de abordagem direcionada e individualizada. Conclusões e considerações para a prática O acolhimento e vínculo propiciado por alguns serviços de apoio resultou em propostas de mudanças e suscitou nas mulheres reflexão, confiança e busca para saída do ciclo da violência. O contrário gerou afastamento dos serviços e consequente permanência junto ao agressor.
Política, gênero humano e direitos humanos na formação do pensamento de Karl Marx
Authors: Sartori Vitor Bartoletti
Published: November 2020

Resumo A partir dos escritos marxianos da Gazeta renana (1842), pretendemos analisar a formação do pensamento marxiano no que toca o tema da política e dos direitos humanos. Intentamos demonstrar que Marx passa de uma concepção ontopositiva do Direito e da política, em 1842, a uma concepção ontonegativa, no final de 1843. O percurso do autor começa com a defesa do Estado político como essenciais à sociabilidade e chega à crítica ao Estado como tal. Neste momento de sua obra, tem-se por essencial a tematização da oposição entre individualidade e generidade; se em um primeiro momento Marx busca o elemento universal da liberdade no Direito, na Crítica à filosofia do Direito de Hegel já enfoca a forma democrática de governo para, então, finalmente, em Sobre a questão judaica, contrapor-se com força a tais teses. O autor procura, então, defender que o indivíduo só se eleva ao patamar de um ser genérico ao recuperar para si suas forças próprias que apareciam estranhadas na política. O ponto de partida para a teoria marxiana passa a ser a crítica ao Direito, à política e à sociedade civil-burguesa.
Reflections on the organization of the Brazilian union in the age of the precariat

Published: November 2020

Abstract This study discusses the paradigmatic shift in the world of work triggered by globalization and the use of telematics and assesses the (in)adequacy of the Brazilian union model to represent the new class of precarious workers. We carried out an exploratory study using a systemic and deductive approach to review bibliographic sources and legislative texts. A perspective of redefinition of the union movement is proposed and we emphasize the importance of collective autonomy as an institute of Private Law for the reconstruction of pacts of collective organization against hegemonies.
Centralizing informal work, complexifying inclusion, decolonizing labour law
Authors: Nicoli Pedro Augusto Gravatá
Published: November 2020

Abstract The article demonstrates how labour regulation is implicated in the process of coloniality, by complexifying the idea of inclusion of informal workers in Brazil. It draws a theoretical and empirical framework to informality, connected to dissident epistemological perspectives, and investigates inclusion from there. The outcome is a critique of the ambiguous ways labour law conceptualizes inclusion and a call for its decolonization.

The so-called outsourcing (subcontracting) question and its regulation
Authors: Dutra Renata Queiroz , Filgueiras Vitor Araújo
Published: November 2020

Abstract Although outsourcing (or subcontracting) has been subject of great controversy, there is predominant consensus over the concept that defines it. The aim of this paper is to discuss this consensus and point out its contradictions, indicating that the casualization of labour related to outsourcing is not a contingency, but corollary of the nature of this way of hiring workers, which tends to reduce the chances of limiting labour exploitation.

Published: November 2020

Resumo Este artigo investiga em que medida o Direito do Trabalho desempenha uma função conformadora da realidade e, ao mesmo tempo, transformadora. Para isso, além de um breve resgate da história do Direito do Trabalho, o artigo analisa os limites da democracia em uma realidade capitalista. A partir disso, iremos examinar a função que a Justiça do Trabalho tem para a manutenção/construção de uma realidade democrática, e mesmo para a superação do modelo hoje adotado e consequente construção de um convívio social que realmente elimine desigualdades, produza distribuição de riqueza e reduza os níveis de violência e discriminação.
Optimal pump selection for variable speed operation in water distribution network

Published: November 2020

ABSTRACT The optimization of pumping stations operation in water distribution networks has been largely studied, especially with the development of speed drivers, which allowed the machines to adjust the hydraulic power inserted to the system according to the demand requirements. Although this approach results in high benefits, the original characteristics of pumps remains the same. Consequently, the pumps can be operating in a range of suboptimal efficiency. Thus, this paper will evaluate the benefits that an optimized pump selection can bring for variable speed operation. The selection of the pumps best efficiency point and the number of pumps operating in parallel are defined applying Particle Swarm Optimization (PSO) to minimize the energy costs of the system. For the case study, the results show that there is no benefit when more pumps are operated in parallel, and that a flexible operational routine significantly reduces the energy expenses, especially when the pump is selected for this purpose.

Abstract: The objective of this work was to determine the effect of L-carnitine supplementation on the productive performance and physiology of juvenile pacu (Piaractus mesopotamicus). A total of 288 pacu, with an initial average weight of 9.62±0.74 g, were fed experimental diets supplemented with 400, 800, 1,200, 1,600, and 2,000 mg kg-1 L-carnitine and a control diet (without supplementation), for 128 days. The following were evaluated: growth performance; carcass centesimal composition; intestinal, muscle, and hepatic histomorphologies; and oxidative stress. The fish hepatosomatic and viscerosomatic fat indexes increased with the inclusion of L-carnitine in the diets. The evaluation of carcass centesimal composition showed that the diets supplemented with 2,000 mg kg-1 L-carnitine caused a reduction in protein content and an increase in that of ethereal extract. Intestinal histomorphology indicated changes in the villi with L-carnitine supplementation. Moreover, hepatic lipid peroxidation occurred with the inclusion of 2,000 mg kg-1 L-carnitine. The supplementation with L-carnitine in the diets of pacu juveniles does not influence the development of the fish until the rate of 1,600 mg kg-1. However, high carcass lipid levels, as well as an increase in the hepatosomatic and viscerosomatic fat indexes, are observed in fish fed diets containing 2,000 mg kg-1.

Abstract: The objective of this work was to evaluate five nonparametric selection indices for the selection of hybrid citrus rootstocks grafted with 'Valência' sweet orange, using horticultural traits relevant for the juice processing industry. Forty-six rootstocks were evaluated in a randomized complete block design, with three replicates and five trees in the plot, in the period from 2009-2015, in a rainfed cultivation. The means of the variables plant height, accumulated fruit yield, fruit yield efficiency, total soluble solids concentration, juice yield, and drought-tolerance were used to calculate the following indices: multiplicative index (IEi), sum of classification (IMMi), genotype-ideotype distance (DiI), and ranking indices (IRKi, based on simple means; and IRKii, based on linear normalization). The indices were efficient to classify the hybrids in relation to general performance. Spearman’s correlation showed a high similarity between most nonparametric indices, notably between IRKi and IRKii. The ranking indices, mainly IRKii, provide a more coherent classification of the hybrids, which allows of the selection of more productive and drought-tolerant rootstocks to produce high-quality fruit for processing.

abstract: The increase in the use of flat slabs and the need of the openings for the passage of installations, such as hydraulic and electrical, which significantly reduces the punching shear resistance capacity of the slab, makes the understanding of the influence of openings in this type of structure extremely necessary. The influence in the structural behaviour of flat slabs with openings at different distances from the column was investigated through five square slabs (1,800 mm x 1,800 mm x 130 mm) supported on square columns (150 mm x 150 mm) tested until failure. The results obtained experimentally were compared with results available in the literature, as well as with responses predicted from the normative instructions. The results confirm high stresses concentration in the region between the column and the opening and that opening situated at 3d from the column have no influence on the failure load for the tested slabs.
Price Discovery in the U.S. Treasury Cash Market: On Principal Trading Firms and Dealers
Authors: Harkrader James Collin , Puglia Michael
Published: November 2020

We explore the following question: does the trading activity of registered dealers on Treasury interdealer broker (IDB) platforms differ from that of principal trading firms (PTF), and if so, how and to what effect on market liquidity? To do so, we use a novel dataset that combines Treasury cash transaction reports from FINRA’s Trade Reporting and Compliance Engine (TRACE) and publicly available limit order book data from BrokerTec. We find that trades conducted in a limit order book setting have high permanent price impact when a PTF is the passive party, playing the role of liquidity provider. Conversely, we find that dealer trades have higher price impact when the dealer is the aggressive party, playing the role of liquidity taker. Trades in which multiple firms (whether dealers or PTFs) participate on one or both sides, however, have relatively low price impact. We interpret these results in light of theoretical models suggesting that traders with only a “small” informational advantage prefer to use (passive) limit orders, while traders with a comparatively large informational advantage prefer to use (aggressive) market orders. We also analyze the events that occurred in Treasury markets in March 2020, during the onset of the COVID-19 pandemic.

Ethnobotany is multidisciplinary science that is on the edge of the Humanities and Natural Sciences, studying the interaction between people and plants. As part of the summer schools, the author's course “Ethnobotany” was tested in the Vetraz sanatorium (Republic of Belarus). The course is aimed at understanding, memorizing, applying, analyzing, creating, evaluating information and engaging students in the development of science. The course program is based on ethnobotanical research projects, which were carried out by students using ethnobotanical methods. The article presents algorithms and results of 3 projects implemented in the vicinity of the city Postavy: 1) the use of wild plants by local residents; 2) ethnobotanical analysis of wild plants promising for decoration and use in everyday life; 3) wild plants used by local people for making tea.

Published: November 2020

Larch forests are most common in the modern high-mountain forests of the Altai. Some relic old-growth Siberian stone pine forests are ingrained to them. Our investigations are fetched out the modern Siberian stone pine forests is the final stage of post-fire succession but the reaching of the stage was possible only in periods with high precipitation levels. The cause which prevents forming of such forests in the modern period in a long time required for the succession as post-fire succession is developing by the inhibition model: successional predecessor species (larch) prevent colonization of successor species (Siberian stone pine) until the disturbance will damage the predecessor population. As a result reaching of the stone pine tree stage may require several hundred years. The fires are usually prevent reaching of this stage.

The data on the species composition and geographical distribution of species of the genus Artemisia L. in the territory of Southern Siberia are presented. During the study of the literature and critical revision of herbarium specimens on the territory of Southern Siberia, 78 species of wormwood were identified belonging to 3 subgenera (Artemisia, Dracunculus Bess., Seriphidium (Besser ex Less.) Fourr) in 7 sections and 20 subsections. A comparative analysis of the species composition of Southern Siberia, as well as the ratio of the belt-zonal and chorological structure, revealed the features of the distribution of species of the genus Artemisia L. in different sectors of Southern Siberia, which are due to modern natural conditions and the specifics of florogenesis.
