Dissertação de Mestrado em Engenharia e Gestão Industrial apresentada à Faculdade de Ciências e Tecnologia O objetivo deste trabalho surge da necessidade de otimizar o dimensionamento e sequenciamento de lotes em linhas de produção paralelas, com tempos de mudança entre famílias diferentes dependentes da sequência de produção, e tempos de mudança independentes da sequência de produção para produtos dentro da mesma família, numa fábrica da indústria de papel, onde são produzidos diversos de papel do tipo tissue. Para tal, e após uma extensa revisão do estado da arte, foi utilizado um modelo eficiente de programação linear inteira mista. O modelo proposto integra três abordagens de modelação diferentes. Uma abordagem discreta é utilizada para o cálculo dos custos de inventário e de backlog. Para o sequenciamento da produção das famílias, é utilizada uma abordagem de tempo contínuo com variáveis de precedência, e o escalonamento dos produtos é feito através de restrições de capacidade e de dimensionamento de lotes.O modelo desenvolvido foi implementado num solver comercial de modo a testar a sua eficiência num problema de dimensão real, e através de dados fornecidos pela empresa foi possível avaliar diversos cenários de operação. Os resultados principais sugerem que quando o sistema não está em sobrecarga, o modelo tende a atingir a solução ótima em tempo computacional muito competitivo, quer no planeamento a curto prazo, quer a médio prazo. Contudo, quando ocorre sobrecarga e havendo possibilidade de não cumprir com as datas de entrega, a qualidade das soluções a médio prazo pode ficar comprometida. É ainda possível concluir que o modelo tende a fornecer melhores soluções do que as atualmente obtidas pela empresa. Desta forma, conclui-se que o modelo formulado tem potencial para ser aplicado em ambientes industriais, no entanto, é importante realçar que compromisso entre o detalhe do modelo e a eficiência computacional terá sempre de ser considerado, por forma a assegurar a automatização eficiente do processo de tomada de decisão. The goal of this dissertation is to optimize the lot sizing and scheduling decisions in parallel production lines, with changeover times between different families depending on the production sequence, and setup times independent of the production sequence for products belonging to the same family, in a factory from the paper industry, where sub products from tissue paper are made.To accomplish this objective, and after an extensive review of the state of the art, an efficient mixed integer linear programming model was used. The proposed model integrates three different modeling approaches. A discrete approach is used for the inventory and backlog cost calculation. For scheduling the families, a continuous-time approach with immediate precedence variables is used, and for scheduling of products, lot sizing capacity constraints are applied.The developed model was implemented in a commercial solver in order to test its efficiency in a real dimension problem. Through data provided by the company, different operation scenarios were evaluated. The main results suggest that when the system is not overloaded, the model tends to reach the optimal solution in very competitive computational time, whether it is short or medium-term planning. However, when an overload occurs, and there is a possibility of not meeting due dates, the quality of the solution in the medium term may be compromised. It is also possible to conclude that the model tends to provide better solutions than the ones currently generated by the company. Thus, it is concluded that the formulated model has the potential to be applied in industrial environments. However, it is important to highlight that the compromise between the detail of the model and computational efficiency must be always considered, in order to guarantee an efficient automatization of the decision-making process.

In the modern world, modern culture has given rise to consumption culture, in which the ownership of goods and objects becomes a language through which the entire society communicates and talks. In modern consumption cultures, the goods are composed of a large number of objects highly differentiated in terms of scarcity and of cost, so that there is always a higher level of consumption to which people can aspire. This article used bibliometrics to quantify and to identify the methodologies used in 56 papers on culture and consumption presented to ENANPADs from 2009 to 2012. Data were collected electronically and analyzed using descriptive statistical methods. The greatest part of the papers were considered ethnographic exploratory qualitative research or netnographic, using the interview for the raising of evidences, which were treated by the technique of discourse analysis. The most relevant conclusions are that the authors are not always concerned about giving this information to their readers, that theoretical research remains unattractive to researchers, and that they reject the use of less common techniques when analyzing qualitative data.

Nesse contexto, o presente trabalho tem como objetivo analisar as dinâmicas ambientais do nordeste sul-mato-grossense, sobretudo do município de Três Lagoas, motivadas pela expansão da silvicultura de eucalipto, fator que ocasionou a transformação da paisagem nos últimos anos (1988-2018). Para tanto, utilizou-se como aporte metodológico o modelo teórico e sistêmico GTP (Geossistema-Território-Paisagem), proposto por Bertrand e Bertrand (2007), como instrumento para a análise ambiental, além de pesquisa documental, coleta e sistematização de dados, pesquisas de campo, visitas técnicas, tratamento digital de imagens de satélite, bem como entrevistas semi-dirigidas junto aos moradores rurais, a fim de mostrar a realidade ambiental local e suas repercussões regionais. Verificou-se que o geocomplexo do referido município sofreu alterações ao longo do tempo, desde o início da sua ocupação, quando instalou-se, na maioria dos estabelecimentos rurais, a agropecuária. A retirada da cobertura vegetal trouxe perdas irreparáveis para o meio natural, acelerando a velocidade dos processos erosivos e a degradação do ambiente. Com a mudança na cobertura e uso da terra (agropecuária-silvicultura), ocorreu uma nova interferência no geocomplexo devido à presença de eucalipto em áreas próximas a corpos d’água, acarretando, entre outros fatores, alterações nos recursos hídricos ou, ainda, devido à retirada da cobertura vegetal para o plantio de novas áreas. Constatou-se, também, que as áreas ocupadas pela silvicultura de eucalipto se intensificaram a partir de 2008, com a chegada das indústrias de celulose e papel e com a necessidade crescente de matéria-prima para a produção. Com isso, averiguou-se uma involução na produção agropecuária do município e região, notadamente a partir da instalação das indústrias. Por fim, constatou-se que os principais problemas ambientais identificados pelos moradores rurais foram: 1) alteração da paisagem; 2) perda de postos de trabalho na agropecuária; 3) ressecamento de corpos d’água; 4) afugentamento de animais; 5) supressão da vegetação secundária; 6) ressecamento de árvores de espécies nativas do Cerrado devido à pulverização aérea com produtos químicos; ou isolamento e sombreamento ocasionado pela densidade de árvores de eucalipto no entorno. Como impacto positivo, destacam-se a geração de emprego e melhorias referentes ao acesso à rodovia. Portanto, as relações e ações promovidas no território, com a instalação do complexo celulósico-papeleiro no município de Três Lagoas, ocasionaram problemas ambientais e repercussões no desenvolvimento local e regional, ao passo que essas empresas igualmente atuam na configuração do espaço, organizando, conforme suas intencionalidades, novas dinâmicas de produção e de ordenamento territorial. The northeast portion of Mato Grosso do Sul (one of the three central-west Brazilian states) is becoming more and more prominent on the national scene as a producer and exporter of pulp and paper, especially the municipality of Três Lagoas. It is one of the largest areas of commercial eucalyptus forests in Brazil, owing to pulp and paper industries, namely Fibria (currently named Suzano), International Paper, and Eldorado Brasil, which were attracted by the region’s natural potential, and by benefits in the scope of tax and credit, infrastructure, legislation, and financing. In this context, this doctoral dissertation aims to analyze the environmental dynamics in northeastern Mato Grosso do Sul, especially Três Lagoas, concerning the expansion of eucalyptus forestry, which caused landscape transformations in the past years (1988-2018). In this regard, the methodological framework of the study comprised the theoretical systemic model proposed by Bertrand and Bertrand (2007), named GTP (Geosystem-Territory-Landscape), which was used as an instrument for the present environmental analysis. Additionally, documentary research, data collection and systematization, field studies, technical visits, digital processing of satellite images, and semi-directed interviews with rural residents were used to help illustrate the local environmental reality and some regional repercussions. It was found that the geocomplex of Três Lagoas has changed over time, since the beginning of its occupation, when farming was practiced in most rural areas. The clearance of vegetation cover inflicted irreparable losses on the natural environment, accelerating erosion processes and environmental degradation. With changes in land cover and use (farming and forestry), there were other interferences in the geocomplex resulting from the planting of eucalyptus near water bodies, causing inter alia alterations in water resources, also due to the vegetation clearance for the planting of new areas. Furthermore, it was observed that the areas occupied by eucalyptus forests have intensified since 2008, with the establishment of pulp and paper industries and the growing demand of raw material. As a result, an agricultural involution process initiated in the studied municipality and region, notably from the undertaking of said industries. Finally, the main environmental problems reported by rural residents comprised: 1) landscape alterations; 2) job losses in farming; 3) the drying up of water bodies; 4) wildlife disturbance; 5) secondary vegetation suppression; 6) the withering of tree species native to Cerrado due to aerial spraying of agricultural chemicals; or the isolation and shading caused by the density of eucalyptus trees in the surroundings. The main positive impacts observed were the creation of new jobs, and improvements regarding access to the main highway. Therefore, the relationships and actions promoted in the municipality of Três Lagoas after the installation of the pulp and paper complex caused environmental problems and repercussions on local and regional development, given that these companies interfere in the space configuration by organizing, at their will, new dynamics of production and spatial planning. El noreste del estado brasileño de Mato Grosso do Sul, en particular el municipio de Três Lagoas, se ha destacado en el escenario nacional como productor y exportador de pulpa y papel, con una de las más grandes áreas de plantaciones forestales de eucalipto con fines comerciales en Brasil. Estas son áreas que resultaron de la implantación de industrias de pulpa y papel, más específicamente Fibria (actualmente Suzano), International Paper y Eldorado Brasil, atraídas por el potencial natural de la región, además de los beneficios tributarios y crediticios, de infraestructura, legislación y financiamiento. En este contexto, el presente trabajo tiene como objetivo analizar la dinámica ambiental del noreste de Mato Grosso do Sul, especialmente Três Lagoas, suscitada por la expansión de la silvicultura de eucalipto, que provocó transformaciones en el paisaje en los últimos años (1988-2018). Para ello, el marco metodológico adoptado fue el modelo teórico y sistémico GTP (Geosistema-Territorio-Paisaje), propuesto por Bertrand y Bertrand (2007), que se utilizó como instrumento para el presente análisis ambiental. Adicionalmente, se recurrió a la investigación documental, recolección y sistematización de datos, estudios de campo, visitas técnicas, procesamiento digital de imágenes satelitales y entrevistas semidirigidas a residentes rurales con el fin de mostrar la realidad ambiental local y su repercusión regional. Se encontró que el geocomplejo del municipio en cuestión ha sufrido cambios a lo largo del tiempo, desde el inicio de su ocupación, cuando se practicaba la agricultura en la mayoría de los establecimientos rurales. La remoción de la cubierta vegetal trajo pérdidas irreparables al medio natural, acelerando los procesos de erosión y la degradación del medio ambiente. Con cambios en la cobertura y uso del suelo (agricultura y silvicultura), se produjo una nueva interferencia en el geocomplejo debido a la presencia de eucaliptos en áreas cercanas a los cuerpos de agua, provocando, entre otros factores, cambios en los recursos hídricos, o incluso debido a la eliminación de la cubierta vegetal para la plantación de nuevas áreas. Además, se constató que las áreas ocupadas por la silvicultura de eucalipto se han intensificado desde el año 2008, tras la llegada de las industrias de pulpa y papel, y la creciente demanda de materias primas. Como resultado, se inició un proceso de involución agrícola en el municipio y en la región, especialmente a partir de la instalación de dichas industrias. Finalmente, los principales problemas ambientales reportados por los residentes rurales fueron: 1) la alteración del paisaje; 2) la pérdida de puestos de trabajo en la agricultura; 3) el secado de los cuerpos de agua; 4) la fuga de animales de la fauna local; 5) la supresión de la vegetación secundaria; 6) la desecación de los árboles de especies nativas del Cerrado debido a la fumigación aérea con productos químicos, o el aislamiento y sombreado provocados por la densidad de eucaliptos en los alrededores. Como impacto positivo, se destacan la generación de empleos y mejoras en el acceso a la carretera principal. Por tanto, las relaciones y acciones impulsadas en el municipio de Três Lagoas tras la instalación del complejo de pulpa y papel generaron problemas ambientales y repercusiones en el desarrollo local y regional, dado que estas empresas interfieren en la configuración del espacio, organizando nuevas dinámicas de producción y ordenación territorial según sus intenciones.

Resumo A indústria de papel gera enorme volume de resíduo de lama de papel. Neste trabalho foi desenvolvido um novo suporte cerâmico poroso usando resíduo de lama de papel como matéria-prima alternativa. Os suportes cerâmicos foram produzidos por prensagem e sinterizados entre 1000 e 1200 ºC. A influência da incorporação do resíduo de lama de papel nas propriedades físicas e microestrutura sinterizada foi investigada. Os resultados indicaram que o resíduo de lama de papel atua como um agente formador de poro. Os suportes cerâmicos produzidos apresentaram massa específica aparente de 1,16 a 2,01 g/cm3, porosidade aparente de 14,6% a 46,7% e tensão de ruptura à flexão de 15,4 a 39,9 MPa. Análise microestrutural indicou que os suportes cerâmicos apresentaram estrutura morfológica altamente porosa. Tais resultados indicaram que suportes cerâmicos contendo até 30% em massa de resíduo de lama de papel têm potencial para serem empregados na fabricação de membranas de filtração. Abstract The paper industry generates a huge volume of paper sludge waste. In this study, a new porous ceramic support using paper sludge waste as an alternative raw material was developed. The ceramic supports were produced by pressing and sintered between 1000 and 1200 °C. The influence of the incorporation of the paper sludge waste on the physical properties and sintered microstructure was investigated. The results indicated that the paper sludge waste acts as a pore-forming agent. The produced ceramic supports showed an apparent specific mass of 1.16 to 2.01 g/cm3, apparent porosity of 14.6% to 46.7%, and flexural strength of 15.4 to 39.9 MPa. Microstructural analysis indicated that the ceramic supports had a highly porous morphological structure. Such results indicated that porous ceramic supports containing up to 30 wt% of paper sludge waste have the potential to be employed in the manufacture of filtration membranes.

Nas últimas décadas, temos assistido ao surgimento de publicações (muitas denominadas “street papers”) que pretendem constituir um canal de visibilidade para a população de rua. Sob uma perspectiva histórica, este artigo estuda o surgimento dessas experiências, tendo como foco central o jornal O Trecheiro, um projeto peculiar dentre os street papers, já que suas pautas voltam-se exclusivamente à realidade da população de rua e de grupos marginalizados. Assim, procuraremos compreender como se dá a representação da população de rua nesse veículo, caracterizada por algumas estratégias principais: afirmação de uma memória coletiva; humanização do sujeito; e ocupação de espaços do jornal por pessoas em situação de rua

The NBOMes are classified as new psychoactive substances and have recently become popular as drugs of abuse, being associated with several intoxication cases and even deaths, leading to its ban in several countries. Until now, the most widely used analytical instrument among forensic laboratories in Brazil is GC-MS. In this study, this instrumentation was employed for routine analyzes of twenty blotter paper seizure by Brazilian Federal Police (BFP) in the southernmost state of the country. However, to acquire more information about these samples, LC-QTOF/MS was used as a supplementary analysis to determinate degradation products, metabolites and unknown compounds. The GC-MS analysis detected only 25B-NBOMe, while the LC-QTOF/MS analysis detected 25B-NBOMe, 2C-B and MDMA. The compounds found in these analyzes are quite different from that found in the national profile of seizures by BFP, suggesting that another rout or supplier act in this region. For research and drug intelligence purposes the use of more versatile, sensitive and specific analytical tool provides a greater number of information that could be employed as a valuable strategy in the drug trafficking combat.

- Abstract
Despite constant medical evolution, the reimbursement policy of Portuguese National Health Service (NHS) for the study and risk stratification of coronary heart disease has remained unchanged for several decades. Lack of adjustment to contemporary clinical practice has long been evident. However, the recent publication of the European Guidelines for diagnosis and treatment of chronic coronary syndromes further highlighted this gap and the urgent need for a change. Prompted by these Guidelines, the Working Group on Nuclear Cardiology, Cardiac Magnetic Resonance and Cardiac CT, the Working Group on Echocardiography and the Working Group on Stress Pathophysiology and Cardiac Rehabilitation of the Portuguese Society of Cardiology, began a process of joint reflection on the current limitations and how these recommendations could be applied in Portugal. To this end, the authors suggest that the new imaging methods (stress echocardiogram, cardiac computed tomography and cardiac magnetic resonance), should be added to exercise treadmill stress test and myocardial perfusion scintigraphy in the available exam portfolio within the Portuguese NHS. This change would allow full adoption of European guidelines and a better use of tests, according to clinical context, availability and local specificities. The adoption of clinical guidance standards, based on these assumptions, would translate into a qualitative improvement in the management of these patients and would promote an effective use of the available resources, with potential health and financial gains., (Copyright © 2020.

Eles apresentam excelentes propriedades elétricas, mas são extremamente frágeis. Então uma alter-nativa seria integrar esses materiais em elastômeros. Assim, para a contornar a fragilidade e a questão de adesão de materiais condutores em substratos alongáveis, neste trabalho é proposto um novo método de fabricação para desenvolvimento de dispositivos eletroquímicos. Inspira-do no sistema redox eficiente das plantas e que está firmemente aderido ao solo pela estrutura das raízes, foi desenvolvido um processo de retardo do fluxo capilar do polidimetilsiloxano (PDMS) na estrutura pirolisada modificada, de forma que fibras pirolisadas integradas no elas-tômero possam garantir adesão e estabilidade mecânica, e que parte delas fique exposta para possibilitar atividade eletroquímica na interface. Baseado no modelo matemático de Lucas-Washburn, as mudanças na superfície das fibras de papel por conta da adição de acetato de celulose e a diminuição do raio dos poros resulta no retardo do fluxo da solução polimérica viscosa na estrutura porosa. Como resultado foi obtida uma superfície de eletrodo de carbono altamente ativa para reações redox. Além disso, testes mecânicos com o dispositivo flexiona-do, dobrado, e alongado, demonstraram que uma deformação linear de até 75% do tamanho inicial não tem efeitos nas propriedades eletroquímicas após o teste. O eletrodo foi ainda fun-cionalizado com polidopamina e azul de Meldola (PDA/AM) para avaliar as atividades eletro-catalíticas e alterar a molhabilidade de superfície. Como resultado o nanofilme permitiu espa-lhamento homogêneo de soluções aquosas na interface do eletrodo, por conta da diminuição do ângulo de contato, e o desenvolvimento de um sistema de auto coleta de amostras líquidas. Além disso, foi possível utilizá-lo como sensor para detecção de NADH através do ancora-mento do mediador redox AM. Testes mecânicos após a funcionalização indicaram que esse sistema do nanofilme cooperativo não altera as propriedades de molhabilidade e atividade eletrocatalítica, de forma que o dispositivo mostrou a mesma performance eletroquímica antes e após ensaios de alongamento. Cellulose and synthetic biopolymers derived carbon materials are extensively used for application in electronic field. They show excellent electrical properties but are extremely fragile and prone to crack. Then an alternative to address this challenge and the adhesion problem reported on literature, a new fabrication route for a flexible and stretchable electrochemical device is proposed. Inspired by trees redox system that is highly adhered on the ground and based on Lucas Wash-Burn model, the pyrolyzed paper is modified with cellulose acetate. Then, in a process named delayed capillary flow of elastomers the surface changes in paper fibers and the decrease in pore radius results in a delay on capillary flow of viscous polymer polydimethylsiloxane (PDMS) solution on its porous structure. As a result, a highly active carbon surface exposed on the top for redox reactions is produced, which shows a remarkable performance and is similar to tree leaves. Also, mechanical deformation studies on the new bendable, twistable, flexible, and stretchable device reveal a linear stretch up to 75%, without effects on its electrochemical properties. These mechanical properties are similar to tree roots highly adhered on the ground. The electrode working area was nanofunctionalized with polydopamine (PDA) that is used for anchoring redox mediators and improvement of wettability with unprecedent homogeneous spreading of liquids and development of self-collection liquid samples. This system is also efficient for NADH detection with Meldola’s blue (MB) redox mediator. In addition, the stretchability property of PDA/MB bionanofilm is exploited and mechanical studies show high electrochemical performance before and after stretch. Código de Financiamento 001

Folhas de grafite pirolisado, (ou simplesmente folhas de grafite) oferecem uma ótima possibilidade de aplicação em sensores eletroquímicos descartáveis, devido ao seu baixo custo, boa condutividade elétrica e térmica, além de alta resistência mecânica. Este trabalho apresenta a melhora na performance eletroquímica da folha de grafite, seja após uma simples ativação eletroquímica em meio ácido usando voltametrias cíclicas ou após o tratamento com plasma frio, usando os gases CO2 e O2. Voltamogramas cíclicos do par redox ferri-ferrocianeto de potássio mostraram maior reversibilidade eletroquímica para as superfícies tratadas, o que corroborou com os resultados obtidos pela espectroscopia de impedância eletroquímica (menores valores de resistência a transferência de carga). Foi possível observar pela microscopia eletrônica de varredura que um maior número de rachaduras é encontrado nas superfícies tratadas, tanto por plasma quanto pelo tratamento eletroquímico, e a espectroscopia Raman mostrou mais defeitos estruturais (maior relação ID/IG), o que pode explicar a melhora na resposta eletroquímica nas voltametrias cíclicas com o par redox. Para avaliar a possibilidade da aplicação destes sensores em eletroanálise, as folhas de grafite foram utilizadas como eletrodos de trabalho para detecção de dopamina, utilizando voltametria cíclica e amperometria. Foram observadas melhoras nas performances eletroquímicas de todas as superfícies tratadas, especialmente para a folha tratada com plasma de CO2. A ativação eletroquímica é uma estratégia simples que proporciona melhora nas propriedades sensitivas da folha de grafite. Apesar disso, as superfícies tratadas com plasma de apresentaram melhor sensibilidade, o que provavelmente é causado pela maior quantidade de defeitos estruturais. Flexible pyrolytic graphite sheets or graphite paper (GP) are a promising source of disposable (low-cost) electrochemical sensors. This work demonstrates the improvement in the electrochemical performance of graphite paper either after a simple electrochemical activation in acid media using cyclic voltammetry or after cold reactive plasma treatment using CO2 and O2 gases. Cyclic voltammetry of the redox probe ferri-ferrocyanide showed higher electrochemical reversibility on the treated surfaces, which was corroborated by the data obtained by electrochemical impedance spectroscopy (lower charge transfer resistance). Scanning electron microscopy revealed a high number of grooves on the treated surfaces after both electrochemical and plasma treatments and Raman spectroscopy showed more structural defects (higher D/G ratios), which may explain the improved cyclic voltammetric response of the redox probe. To evaluate the possible application of these sensors in electroanalysis, the graphite paper was evaluated for dopamine detection using cyclic voltammetry and amperometry under flow conditions. Improved performance on treated surfaces, especially after CO2-plasma treatment, was verified. The electrochemical activation is a simple strategy to improve the sensing properties of graphite paper; however, cold-plasma treated surfaces provided better sensing properties probably due to the production of higher number of structural defects.

In this article we aim to analyze the effective practices of students in the 2nd grade of high school when they perform tasks on the representation of geometric solids in the paper/pencil environment, based on the manipulation of Concrete Object Construction Project (PCOC) models, obtained by rapid prototyping on the 3D printer. For that, we appropriated the Institutional Analysis and Didactic Sequence as a research methodology. We immerse our studies in the theoretical framework constituted by the Anthropology Theory of Didactics, with emphasis on its praxeological approach, to provide us with elements of analysis of the techno-theoretical techniques and speeches in Spatial Geometry, mobilized by the students in their effective practices. The results reveal that students can represent the solids considered in the paper/pencil environment but do not indicate or describe the techniques they use in the referred representations during their effective practices. Therefore, this is a problem of the reference institution, particularly the 2nd grade of high school, which does not provide training to students involving the indications and descriptions, as we proceeded in developing our a priori analysis around the PCOCs that we worked on with these students.

This article focuses on initial teacher education, in the development of teaching study tasks, especially related to the end-of-course work. The research question is: Which reasons support the mathematics undergraduates' choices for the theme and development of the end-of-course work? In connection with the problem, this research analyzes the reasons that justify undergraduates' choices in the production of that work. The text is based on historical-cultural theory, with emphasis on the psychological and didactic principles of activity theory, on the development of students' reasons and meanings when faced with the social meanings of initial education. The methodology is developed through a formative pedagogical intervention carried out with two mathematics undergraduate students. The data production has an empirical reference in the transcripts of interviews and moments of collective advice for the development of academic work materialized in article format. The analysis is carried out from the perspective of historical-dialectical materialism, which demonstrates results through the reasons that lead students to create meanings of their experiences in the development of initial training, especially during the training processes throughout graduation. In addition to these cases, the persuasion of peers was also observed, demonstrating relationships on the theoretical-methodological/ideological orientations in their perceptions about the pedagogical activity in the interventions carried out.

This study faces the problem of female participation in politics, since historically they are excluded of elections. The Article 10, paragraph 3, of Law 9,504 / 97 establishes electoral gender quota rule. This device has been changed with the electoral reform of 2009 (Law 12,034 / 09). Takes care here the state that provides for inclusion minority that has no representation in homes to legislate, in an attempt to correct the distortion caused historically in representative democracy. But the literature used showed that until now this device was not successful, because it is urgent to change other parts of the Brazilian electoral system, and the promotion to empower women, not only in terms the right to vote and be voted on, but in the other freedoms inherent in their economic and social development, without which moves away from the promotion of human dignity.

Ten years ago the first version of the guiding document of the National Curriculum Guidelines (DCNs) was published, for the formation of bachelors in Journalism, and no longer in Social Communication. Almost simultaneously, the Supreme Court announced the end of the diploma requirement for professional practice. These apparently antagonistic facts impacted the demand for the course, the professional identity and the profile of the Brazilian journalist in the second decade of the third millennium. From the observation of the Undergraduate Conclusion Papers (TCCs), prepared by future bachelors in Journalism - and no longer in Social Communication, graduated at the Niterói campus of Estácio de Sá University, between 2014-2018, we sought to identify theoretical and perceptions of the changing professional identity.

Teatros de papel 1765-1860. ¿construcción de un modelo “a la francesa”?ResumenDesde mediados del siglo XVIII, la arquitectura teatral fue objeto de múltiples debates por cuanto ya no satisfacía las exigencias de la puesta en escena, ni del público que demandaba cada vez más comodidades. Las reflexiones teóricas se orientaron, entonces, hacia la búsqueda de una arquitectura para el espectáculo, adaptada a los hábitos y las prácticas de la sociedad francesa. En el presente artículo se propone analizar –—a partir del estudio de una serie de escritos publicados entre finales del siglo XVIII y mediados del siglo XIX—, los diferentes modelos teóricos que alimentaron la conceptualización de la arquitectura teatral, los cuales resultaron tan diversos como lo eran los perfiles y las trayectorias de sus autores. Las propuestas teóricas ofrecieron una amplia variedad de modelos que no convergen hacia una solución única; de la misma forma, fue posible encontrar entre aquellos teatros construidos, la coexistencia de numerosas variantes tipológicas.Palabras clave: arquitectura francesa, diseño arquitectónico, teoría arquitectónica, tipología arquitectónica, salas de espectáculos.Paper theaters 1765-1860. Building a «French» model?AbstractSince the mid-eighteenth century theater architecture was much debated because it no longer met the requirements of staging and the public was demanding more and more amenities. The theoretical reflections were then directed towards the searching for architecture for the show, adapted to the habits and practices of French society. In this article we propose to analyze, from study of a series of papers published between the late eighteenth century and the middle of the nineteenth century, the various theoretical models that fueled the conceptualization of theater architecture, which were as diverse as were the profiles and trajectories of their authors. The theoretical proposals offered a wide variety of models that do not converge into a single solution and in the same way, it was possible to find among those built theaters, the coexistence of numerous typological variations.Key words: French architecture, architectural design, architectural theory, architectural style, theaters.Théâtres de papier 1765-1860.

The Portuguese Journal of Behavioral and Social Research requires authors to follow the recommendations of the Publication Manual of the American Psychological Association (APA, 2010) in the presentation of statistical information. One of the APA recommendations is that effect sizes should be presented along with levels of statistical significance. Since p-values from the results of the statistical tests do not indicate the magnitude or importance of a difference, then effect sizes (ES) should reported. In fact, ES give meaning to statistical tests; emphasize the power of statistical tests; reduce the risk of interpret mere sampling variation as real relationship; can increase the reporting of “non-significant"results, and allow the accumulation of knowledge from several studies using meta-analysis. Thus, the objectives of this paper are to present the limits of the significance level; describe the foundations of presentation of ES of statistical tests to analyze differences between two groups; present the formulas to calculate directly ES, providing examples of our own previous studies; show how to calculate confidence intervals; provide the conversion formulas for the review of the literature; indicate how to interpret the ES; and show that, although interpretable, the meaning (small, medium or large effect for an arbitrary metric) could be inaccurate, requiring that interpretation should be made in the context of the research area and in the context of real world variables.

This research project revolves around the properties of text linguistics under a qualitative approach. The author analyzed drafts of a research paper by two university students as well as lesson plans and textbooks of high school Spanish Language and Literature courses and lesson plans of courses from the Licentiate degree in Education. According to the information from the drafts, students struggle with coherence and cohesion in writing; however, they succeed in choosing the correct language for the type of writing. Difficulties are most likely due to fact that this topic is not included in secondary education plans and is not commonly addressed in textbooks or university classes. In conclusion, teachers should include the properties of text linguistics in their lesson plans in order to help students overcome these difficulties.

Therapeutics. Pharmacology ,RM1-950 - Abstract
Objective The pharmacies and wholesalers’ remuneration system for the provision of medicines in Portugal went under structural changes with the Memorandum of Understanding in 2011, which intensified the degree of public pharmaceutical expenditure reduction requirements, in exchange for the financial international assistance. The objectives of the present study were: to provide an overview of the changes, its impact for pharmacies and recent advances towards a more comprehensive system. Methods Literature review and identification of changes; market analysis and distribution margins were computed using two nationwide databases with representative pharmaceutical dispensing data from ambulatory care; impact of changes and implications for the sector and pharmacies was accessed. Statistical analysis was performed using Statistical Analysis Software (SAS), Guide v4.1. Results The fixed linear remuneration system was replaced in 2012 by a regressive mark-up and minor fees system, per price range, determining the greatest modification to the distribution remuneration system during the last decades. An adjustment was made in 2014. The pharmaceutical market and the National Health System expenditure were reduced by 876 and 494 million euros, respectively, over the past four years. The loss of pharmacy and wholesaler remuneration was 322.8 million euros, higher than the established objective of 50 million euros. Conclusion Policy changes, reinforced with the Memorandum of Understanding, caused a large reduction in the remuneration of pharmacies, directly through cuts in margins and indirectly through decreases in prices. Several studies, published in the meantime, support the difficulties for the sector sustainability. Published in: Pharmacoeconomics. 2018: 3:117.

We present a complete Portuguese translation of the 1896 paper by Charles Édouard Guillaume (1861-1928) about the temperature of interstellar space. The importance of this work is that it is the oldest estimate known to us of the temperature acquired by a body which is in interstellar space far away from other stars. This temperature would be due to an equilibrium state in which the radiation received by this body from the stars around it would be equal to the radiation emitted by this body. This estimative happened prior to the birth of George Gamow (1904-1968) who is considered erroneously in many textbooks as being the first person to have predicted this temperature.
