Resumo O presente trabalho faz uma investigação das relações entre neoliberalismo, Estado de Exceção e controle social na contemporaneidade do Brasil. Assim, o problema que move este artigo se coloca: diante dos elementos de exceção e de neoliberalismo, pode-se dizer que o controle social da Administração Pública já se constitui uma mera ideia vazia de significado? A hipótese é a de que sim, é possível falar em decadência do controle social, principalmente por meio de um de seus principais mecanismos, o acesso à informação. O método de trabalho é o hipotético-dedutivo, testando-se a hipótese a partir da argumentação desenvolvida.

Abstract The present work deals with an investigation of the relations between neoliberalism, the State of Exception and social control in contemporary Brazil. Thus, the problem that moves this article arises: in the face of elements of exception and neoliberalism, can it be said that social control is already a myth, a mere empty idea of meaning? The hypothesis is that yes, it is already possible to talk about the decay of social control, mainly through one of its main mechanisms, access to information. The working method is the hypothetical deductive, testing the hypothesis based on the arguments developed.
Resumo Este artigo discute a visão de poder constituinte de Antonio Negri à luz da teoria do direito de Franz Neumann. O texto apresenta as características essenciais do constitucionalismo e a sua crítica por Negri (2015) no livro O Poder Constituinte. Para Negri (2015), o constitucionalismo tem como função central impedir a transformação social radical por meio da contenção do poder constituinte. A seguir, o texto discute essa crítica à luz de Franz Neumann (2009; 2013) procurando mostrar que nem toda transformação radical é necessariamente progressista, especialmente se deixar de lado algumas garantias presentes na tradição do constitucionalismo.

Abstract This article discusses Antonio Negri’s view of the constitutive power in the light of Franz Neumann’s theory of law. The text presents the essential characteristics of constitutionalism and its critique by Negri (2015) in the book “The Constituent Power”. For Negri (2015), constitutionalism has as its central function to prevent radical social transformation by restraining the constituent power. Next, the text discusses this criticism in the light of Franz Neumann (2009; 2013), seeking to show that not all radical transformation is necessarily progressive, especially if we leave aside certain assurances present in the tradition of constitutionalism.
Resumo Neste trabalho serão discutidos os avanços e os retrocessos no direito constitucional e no direito internacional no pós-guerra. Analisa-se o mundo que emerge normativamente mais igual após a Carta da ONU, a Declaração Universal dos Direitos Humanos e os Pactos de 1966, aproximando-se de um constitucionalismo global, porém permanece desigual no plano fático. A pesquisa foi realizada por meio de revisão bibliográfica.

Abstract The paper discusses advances and setbacks in constitutional law and international law in the postwar period. Analyzes the world emerges more equal normative guidance after the UN Charter, the Universal Declaration of Human Rights and the Covenants of 1966, approaching a global constitutionalism, but remains uneven in factual plan. The research was conducted through literature review.
Studies conducted in the field of education have, in many cases, highlighted the little insertion of teaching and learning theories in Natural Sciences classes, in Higher Education. We developed this study to analyze how Chemistry professors take ownership of a historical case to explain the concepts they develop in their classes. To do so, we analyzed this record of undergraduate classes, at times when professors related pedagogical link-making to the future field of work of the students, using the “Thalidomide case.” We realized that, by showing the importance of studies involving chirality and related concepts, the students’ attention to the content seems to have increased significantly, which expands the possibilities of construction of meaning. Thus, we argue that the pedagogical link-making can significantly contribute to students’ knowledge.
The trunk bark of Tabebuia caraiba Bignoniaceae was found to contain four novel iridoids, 6-O-E-p-coumaroyljioglutin D (2), 6-O-E-p-coumaroyl-3-demethyl-3-O-ethyljioglutin D (3), 6-O-E-p-coumaroyl-1-demethyl-1-O-ethyljioglutin D (4), 7-O-E-p-coumaroyljiofuranaldehyde (5), three known iridoids, including one iridoid glucoside, jioglutin D (1), rehmaglutin D (6), 6-O-E-p-coumaroylcatalpol (7). From the flowers were obtained six triterpenes, betulinic acid (8), olean-12-en-3-one (9), β-amyrin (10), oleanolic acid (11), ursolic acid (12), 3-O-E-p-coumaroylursolic acid (13), 2α-hydroxyursolic acid (14), 6β,19α-dihydroxyursolic acid (15), and one phenylethanoid, tyrosol (16), in addition to β-sitosterol, β-sitosterol-3-O-β-D-glucopyranoside and β-sitosterol-3-O-β-D-(6´-O-acyl)-glucopyranoside and E-p-coumaric acid. The structures of the isolated compounds were established on the basis of 1D and 2D NMR spectroscopic techniques. The chemical profile of the trunk bark of the plant was determined by HPLC/DAD/HRESIMS and did not present a good correlation with the phytochemical study. It did not detect most of the isolated substances and allowed to propose the presence of some non-isolated compounds.
On May 2019, the members of the Anthropocene Working Group completed a binding vote to affirm some of the key questions that have been agreed in 2016: the Anthropocene should be considered as a formal chronostratigraphic unit, defined by a Global Boundary Stratotype Section and Point (GSSP), using one of the stratigraphic signals around the mid-twentieth century of the Common Era. The fallout from nuclear weapons testing appears as the most suitable GSSP. In this article, the main anthropogenic markers are discussed as well as the sources or human-made radiation and the signature of nuclear weapons testing. The appearance of 239+240Pu in the early 1950s and the clear peak, in 1963, makes a good marker. High resolution archives include layers of sedimentary rocks, lacustrine and marine sediments and corals and polar ice cores. A coupled application of other radioactive isotopes, as 137Cs, 14C and 241Am, may be useful to categorize distinct fallout signatures. A site to define the Anthropocene (golden spike) would ideally be located between 30º and 60º north of the equator. Nevertheless, results obtained in sediments on the Brazilian coast showed that both 239+240Pu and 137Cs signatures could be detected and quantified as markers of this “atomic age”.
A highly sensitive ultra-performance liquid chromatography tandem mass spectrometry method for the determination of Docetaxel and metabolites (M1+M3) in human plasma samples was developed and validated. The method employs a liquid-liquid extraction and a reversed phase separation Acquity® C18 column BEH C18 (150 x 2.1 mm, 1.7 µm). Mobile phase was a mixture of formic acid 0.1% (eluent A) and acetonitrile plus 0.1% formic acid (eluent B) in isocratic mode. Total analytical run time was 7 min. The interval of method linearity interval was 50 to 3000 ng mL-1 for docetaxel and 5.0 to 300 ng mL-1, for M1+M3 metabolites. Intra-assay and inter-assay precision was coefficient of variation 2.5-15.7% and 5.9-12.6%, respectively and accuracy was 89.0-114.0%. The method was successfully applied in the measurement of docetaxel plasma levels and area under the curve calculation in 31 cancer patients, demonstrating adequate analytical performance for the clinical application in the therapeutic drug monitoring and pharmacokinetics studies.
In recent years, great advances have been observed in the proteomic area regarding the different approaches adopted as top-down, middle-down and bottom-up. Regarding middle-down and bottom-up approaches, a previous step for protein digestion is necessary for further analysis of the generated peptides. Classical digestion protocols employing proteases are usually carried out in solution, which can lead to a number of disadvantages such as high digestion time, enzymatic autolysis and impossibility to reuse the enzymes. In view of these drawbacks, different approaches have been studied and applied for improving enzymatic efficiency, inhibition of autolysis, reduction of digestion time, and to minimize the number of missed cleavages. In the literature, great efforts have been made in order to achieve maximum efficiency in enzymatic digestion, with emphasis on proteases immobilization. In this review, concepts related to protein digestion, immobilization techniques, as well as the main support used for enzyme immobilization are discussed considering new tools for proteomic analysis.
Real-world vehicle emissions of carbonyls compounds (CC) were determined at the Rebouças Tunnel, Rio de Janeiro (Brazil). The tunnel is a two-bore tunnel with three lanes in each direction and has a length of 2840 m, divided in two sections. On average, approximately 5,000 vehicles (95% light duty) were passing the tunnel per hour. Sixteen samples were simultaneously collected 500 and 1500 m inside from the entrance. The main CC were formaldehyde, acetaldehyde, acetone, propionaldehyde and benzaldehyde. A total of 16 samples were collected in each point in 8 different days. In 5 days, CO and CO2 were also monitored during the sampling period. Emission factors were calculated. Using the Pierson method, emission factors were 7.5 ± 2.6 and 13.8 ± 5.7 mg km-1 for formaldehyde and acetaldehyde, respectively. Using the fuel consumption method, values were 6.3 ± 2.1 and 11.8 ± 3.9 mg km-1 for the same compounds. The differences between both methods were lower than 20% and may be considered acceptable considering all the approximations in the calculations. Ozone forming potentials (OFP) were also estimated as 90.4 ± 37.3 and 70.7 ± 24.6 mg km-1 for formaldehyde and acetaldehyde, respectively.
A new method to identify the authenticity of Brazilian banknotes (R$) is proposed using digital image analysis by a smartphone application, Photometrix®, associated with chemometric tools. Authentic banknotes (n = 4) obtained in local bank and falsified (n = 12) by the author himself by means of three printers (laser-Deskjet®, wax-Color Qube® and inkjet-Deskjet®) were used for the development of the methodology. An experimental planning was performed to evaluate the authenticity of the banknotes determining: the best region (holographic band, tactile region in the lower left and right upper number, effigy microimpressions, lower number left, animal figure, watermark and puzzle); Region of Interest (ROI) (16x16; 32x32 and 64x64 pixels), focal length (8, 12, 15 and 20 cm) and variation of the smartphone (Motorola G5 Plus, Samsung S7 and LG K10). The best regions chosen were effigy microimpressions and round the animal. Promising results were obtained from ROI 16x16 pixels with focal length fixed at 10 cm. Thus, the application presents promising features for analyzing the authenticity of banknotes by digital images making it fast, non-destructive, portable, with low cost, and can be accessed by all society.
The ability to monitor the spread of diseases is essential for prevention, intervention and control practices. In this context, wastewater-based epidemiology (WBE) has been applied to empirically evaluate the exposure of populations to chemical substances and pathogens of emerging concern in near real time. During the current COVID-19 pandemic, WBE remains an innovative epidemiological tool, with the potential to complement infectious disease surveillance systems. Recent studies on WBE and COVID-19 are based on the monitoring of viral RNA fragments as target biomarkers for SARS-CoV-2 via RT-qPCR and allied techniques. Literature results have been shown the potential of WBE as an innovative tool to monitor viral spread in large communities, map contagion curves and hotspots, identify the contribution of asymptomatic individuals, and subsidize early warning systems for disease outbreaks. WBE can offer less expensive responses for monitoring large populations compared to individual clinical tests which are not feasible on large scales. This aspect is important in terms of health surveillance and associated public policies, notably where clinical tests are scarce or underestimated and in less developed regions with inadequate sanitation conditions.
In Brazil, the continuing education of chemistry teachers has recently begun to form part of a broader public policy: the Professional Master Programs for the Qualification of Teachers of the Public Basic School (ProEB). The overall objective of these programs would be to contribute to the professional development by conducting qualified and current research that seeks to improve professional practices. Specifically, this article aims to present the perceptions of students and teachers in the initial phase of implementation of the Professional Master of Chemistry in National Network (PROFQUI). In this sense, the following are addressed: a) the aspects of teacher education in undergraduate chemistry courses; b) the continuing education of these teachers; c) the proposal of the professional masters, with special attention to PROFQUI; d) the initial data from a longitudinal survey involving 44 chemistry teachers and 27 university professors, collected from 6 higher education institutions participating in the PROFQUI. In short, it can be concluded that teachers of basic education seek from their professional development to improve the teaching of school chemistry. In this sense, such intended improvements are not only about scientific updating in chemistry, but also about didactic resources and possible practices and activities that contribute to their professional performance.
Resumo Este artigo investiga os desafios que as mídias sociais apresentam em relação ao poder das cúpulas dos partidos de definir o discurso majoritário. A hipótese é de que, em contexto de fragmentação partidária, as mídias sociais oferecem oportunidades para correntes internas vocalizarem insatisfações e negociarem suas agendas publicamente, o que gera ruídos externos e dificulta consensos. O estudo de caso focaliza as disputas travadas entre diferentes facções do PSOL acerca da aliança com PT, PCdoB e Rede na eleição para a prefeitura do Rio de Janeiro em 2016. Coletamos dados a partir de requisições à Graph API para mapear a presença de lideranças, diretórios, facções e núcleos dos quatro partidos. Os achados indicam a distância estrutural entre os subsistemas comunicativos organizados em torno do PSOL e do PT-PCdoB e a ríspida discussão pública sobre a composição da aliança eleitoral.

Abstract This paper investigates the challenges posed by social media to the directive head of the parties to define the majority discourse. The hypothesis is that in a context of party fragmentation, social media offer opportunities for internal currents to vocalize dissatisfactions and to publicly negotiate their agendas publicly, which generates external noise and hinders consensus. The case study focuses on the coalition negotiations among PSOL factions, PT, PCdoB and Rede for the 2016 Rio de Janeiro City Hall election. This study has collected public data by querying the Facebook Graph API, searching fan pages of leaders, directories, factions and local representations. The sample is composed of 189 pages, from which 54 are connected to PSOL organization and 10 factions. The findings indicate the structural distance between the communicative subsystems organized around PSOL and PT / PCdoB, with separate clusters on Facebook and a strong public discussion about the composition of the electoral alliance.


Résumé Cet article examine les défis que les médias sociaux présentent pour le pouvoir des sommets de partis de définir le discours de la majorité. Sur la base de l’approche organisationnelle théorique de la communication entre partis, l’hypothèse est que les médias sociaux fragmentent la communication entre partis divisés et offrent aux courants internes la possibilité d’exprimer leur mécontentement et de négocier publiquement leurs programmes. L’étude de cas porte sur les différends entre différentes factions du PSOL sur l’alliance avec PT, PCdoB et les élections du conseil municipal de Rio de Janeiro en 2016. Nous avons collecté des données à partir de demandes adressées à Graph API afin de renforcer la présence de dirigeants, répertoires, factions et noyaux des quatre partis, comprenant un échantillon de 189 pages de fans, dont 54 représentent le PSOL, dont 10 factions. Les résultats indiquent la distance structurelle entre les sous-systèmes de communication organisés autour du PSOL et du PT / PCdoB, avec des clusters séparés sur Facebook et un débat public animé sur la composition de l'alliance électorale.
Resumo O objetivo do texto é analisar os atos legais, que levaram ao afastamento do poder do último governador Setecentista de Pernambuco. O artigo evidencia o papel da comunicação política e o trâmite jurídico escolhido pelos denunciantes para que a Coroa portuguesa aceitasse punir D. Tomás José de Melo do governo da capitania, e julgá-lo na Corte, em um dos seus tribunais. A pesquisa explora a documentação colonial do Arquivo Histórico Ultramarino, buscando compreender o trâmite jurídico e o processo instaurado contra o governador, concluindo que a aplicação da justiça, mesmo no final do século XVIII, continuava sendo uma prerrogativa do monarca e ainda cabia ao rei dar a cada um o que era seu de direito.

Abstract The purpose of the text is to analyze the legal acts that led to the removal of the power of the last governor of eighteenth century Pernambuco. The article highlights the role of political communication and the legal process chosen by his accusers so that the Portuguese Crown agreed to punish D. Tomás José de Melo by removing him from his role in the captaincy and trying him in court in Lisbon. The article explores the colonial documentation of the Overseas Historical Archive, seeking to understand the legal process and the case taken against the governor, concluding that, even at the end of the eighteenth century, justice was still a prerogative of the monarch who was responsible for giving each one what was theirs by right.
Resumo Neste artigo, discutimos narrativas sobre as relações afetivo-sexuais de homens jovens vivendo com HIV/aids, com carga viral indetectável e possibilidade de não transmis-sibilidade do HIV. Realizamos dez entrevistas semiestruturadas com homens que fazem sexo com homens, entre 18 e 30 anos, acompanhados em um SAE - Serviço de Assistência Es-pecializada de Salvador-BA, em 2017. Nas narrativas em foco, a condição de indetectável aparece como uma mudança [bio]identitária importante, e sua manutenção como uma res-ponsabilidade contínua consigo e com o outro. Apesar de avanços biomédicos e das novas possibilidades interativas abertas nesse cenário, os efeitos estigmatizantes do HIV persistem, sustentados pelos discursos de medo e culpa por uma possível transmissão do vírus. Uma noção de corpos perigosos, de risco, em detrimento dos avanços alcançados com os estudos que indicam que indetectável=intransmissível.

Abstract In this article, we discuss narratives on affective-sexual relationships of young men living with HIV/AIDS, with undetectable viral load and possibility of not transmit-ting HIV. We conducted ten semi-structured interviews with men who have sex with men, aged between 18 and 30 years old, followed at a specialized health service in Salvador, Ba-hia, Brazil, in 2017. In these narratives, the undetectable condition appears as an impor-tant [bio]identity change, and its maintenance as an ongoing responsibility to themselves and others. Despite biomedical advances, the ‘undetectable equals Untransmittable’ (U=U) campaign and new interactive possibilities open up in this scenario, the stigma of HIV as well as a notion of dangerous/risky bodies persist, supported by discourses of fear and guilt for a possible virus transmission.
RESUMO Neste artigo, utilizamos depoimentos de agentes pioneiros na criação de festivais e lojas especializadas em rock em Pernambuco para reconstruir os fragmentos de uma rede de sociabilidade em torno desse gênero musical nos anos 1970. Todos fazem referência a experiências marcantes vivenciadas na casa de Humberto Brito, distribuidor informal de lançamentos importados raros na cidade. Utilizando a noção de “mediação cosmopolita”, elaborada a partir das contribuições de Latour (2012), Silverstone (2002) e Robbins (1992), tentamos compreender de que maneira se desenvolve a constituição de determinado gosto e de um modo específico de se relacionar com a música naquele contexto.

ABSTRACT In this article, we analyse interviews with pioneering agents in the creation of rock’nroll festivals and music stores in Pernambuco in order to reconstruct the fragments of a sociability network related to this musical genre, in the 1970s. They all refer to remarkable situatons experienced at Humberto Brito’s house, an informal distributor of rare imported Long-plays in Recife. We use the category “cosmopolitan mediation”, elaborated from the contributions of Latour (2012), Silverstone (2002) and Robbins (1992) in order to understand how a certain taste and a specific way of relating to music are structured in that context.
RESUMO Este artigo tem como foco as ideias de Mário de Andrade sobre a importância do patrimônio histórico e artístico nacional. Defende-se que a posição do escritor é informada por uma perspectiva vanguardista e revolucionária. Nesse quadro, a tradição não vale por si mesma, mas na medida em que comporta um aproveitamento contemporâneo e transformador, tanto na esfera artística quanto na esfera política.

ABSTRACT This paper is focused on Mário de Andrade’s ideas about the importance of national historical and artistic heritage. We argue that the writer’s position is informed by an avant-gardist and revolutionary perspective. In this context, the value of tradition does not stand on its own, but insofar as it admits a contemporary and transformative use, both at aesthetic and political spheres.
resumo Considerando a centralidade das mulheres no cuidado, quer gratuito quer mercantilizado, verificaremos, numa abordagem comparada, os principais pontos de convergência e divergência no trabalho de cuidadoras/es de idosos no Brasil, França e Japão, de modo a apreender as formas de organização e realização do trabalho de cuidado como relação social e interindividual. A diversidade dos contextos social, econômico, político e cultural no seio dos quais se realiza o trabalho de cuidado é tratada aqui de maneira central. O artigo considera a divisão sexual do trabalho de cuidado, a relação subjetiva ao trabalho e o papel do trabalho emocional, levando em conta as características individuais e as trajetórias profissionais e pessoais das cuidadoras. Queremos mostrar como o gênero, a raça e a classe social coconstroem essas trajetórias.

abstract Women are central in paid and unpaid care work. With a comparative approach, this article studies convergences and divergences in elderly care in Brazil, France and Japan. It examines the forms of organizing and performing care work in terms of social and inter-individual relations. The diversity of social, economic, political and cultural contexts is considered. This article broaches the sexual division of care work and the workers’ subjective relation to their labor, including its emotional aspects. It also takes into account individual characteristics, as well as the professional and personal trajectories of care workers. It shows how gender, race and social class co-construct the workers’ trajectories.
