Previsão do preço de ações brasileiras utilizando redes neurais artificiais

The stock market analysis is influenced by the upward and downward trend related to the asset prices in relation to short periods. Due to the feelings and the expectations of investors, which can affect the movement of shares. One of the possibilities to maximize the returns in stock forecast is to predict the directional asset movement instead of forecasting the prices. This paper analyses the use of artificial neural networks to preview the directional asset movement and compares the performances of two architectures: LSTM and GRU. Shares and Ibovespa index are analyzed in several time horizons aiming at the observations of specific patterns. The performance of the said architectures is very similar to each other: for short time horizons, the LSTM architecture presented a better accuracy, and for long time horizons, the GRU is more accurate than LSTM.

Tradução, adaptação cultural e validade de conteúdo do programa de treinamento espanhol “empecemos” para pais

Recently lots of changes occurred when it comes to family models: the number of caregivers, the school model, the children's daily activities and the excessive amount of stimuli. These factors caused researchers to acknowledge such phenomena and to think about the importance of parental psychologic interventions as an instrument to prevent or improve behavioral problems in early childhood. Studies have shown that there are many benefits resulting from good parental practices; but programs in Brazil lack structure and methodological clarity, making it difficult to analyze their results and to use them. For that matter, a training that is very effective regarding interventions is called Empecemos, a Spanish program of parental intervention designed in 12 sessions to be deployed in a group of parents or caregivers of children between ages 5 to 11. Empecemos aims to potentialize positive interactions with children through positive reinforcement and shared activities. The goal of the present study was to translate, to adapt culturally and to validate the content inside of the program's manual so it may be suitable to use in Brazil. To do so, this work was divided into five phases: 1) authorization from the original author; 2) translation of the manual to Brazilian Portuguese by a professional that is native to Spanish language and fluent in Portuguese, and by another native in Brazilian Portuguese and fluent in Spanish; 3) cultural adaption of diverging words and expressions between the two translations; 4) synthesis of the two translated manuals and 6) validity of content, executed by five psychologists who are experts in parental interventions to attest if the content semantically equals the original text. Results show an average of 83,3% of positive margin for all sessions translation and adaptation and 95,8% off approval regarding the program’s format. This indicates that the program’s version in Brazilian Portuguese equals semantically and objectively to the original Spanish text and that it presents itself as a better structured alternative for deployment in Brazil.

Linha 10 turquesa da CPTM: a difícil transformação de uma ferrovia de cargas para o transporte de passageiros

The city of São Paulo and the metropolitan region are closely linked to the history of the railroad, especially the lines of the corridor Santos to Jundiai corresponding to the first railway in the state of São Paulo. This rail link has provided the conditions for economic development of São Paulo, for streamlined coffee transport towards the port for export in a later period attire, distributed raw materials, products and industrial workers. The railroad was the means by which the metropolization form of São Paulo, took form with the railway stations becoming the centrality of the locations that later originated several municipalities, among which the leading center of the region known as "Grande ABC" (Great ABC), heavily industrialized region, of great importance in the national economic scenario. The adoption of road development policies from the second half of the twentieth century, at the expense of pre-installed railway infrastructure contributed to the stagnation of this mode of transport, which has suffered the reduction of public resources for modernization and also by reducing of industrial activity on its edge, attributed to changes in the economy that discouraged the industrial concentration in large urban centers. After its attempt to rescue the railways its of the general context of country’s the transport at on framework, the federal government privatized the cargo railway and handed to the state administration passenger transport system, in the 1990s. The CPTM (Paulista Company of Metropolitan Transportation), result of this second action, the has been making efforts in the recovery and improvement of the railway system of passengers, applying resources in the recovery and improvement of all the railways, providing passenger transport services in the RMSP (São Paulo Metropolitan Region). Among its six lines, one sees an imbalance in the implementation of these improvements in practice; mitigate the metropolis of mobility problems. Line 10 - Turquoise is the most recent one to receive improvement Works, despite connecting the Bras station to the municipality of Rio Grande da Serra, through the Great ABC, once industrial cities and reasonable economic development. This imbalance is even more noticeable when comparing Line 10 - Turquoise to Line 9 - Emerald, the only fully modernized line and meets the most developed region of the City of São Paulo, focusing the portion of the population with the highest income and the new tertiary economic pole located in the Luiz Carlos Berrini and Faria Lima region. A more detailed analysis shows that this imbalance is caused by more complex economic factors related the movement of cargo through the port of Santos, whose line 10 - Turquoise CPTM still plays an important complementary role in cargo flow. This study aims and presents the operational peculiarities of the rail system, display the particular difficulties of Line 10 - Turquoise, which still lives strongly with the activity of cargo transportation due to remnants of linked industrial activity to the railroad, causing an interference directly related to their operational performance with regards to passenger transportation.

Aurelio Martinez Flores : a produção do arquiteto mexicano no Brasil (1960-2015)

Aurelio Martinez Flores (1929-2015), a Mexican architect based in Brazil, left throughout his professional life important contributions that take form in different fields: design, interiors and architecture. His legacy, at the same time indelible and anonymous, is revealed in his works and those of his disciples. His initiation working for furniture stores in Puebla, where he was born, gave him the architecture path in the university, and the vocation to head the production line of the American branch in Mexico City of the leading manufacturers of modern furniture in the twentieth century – Knoll International –, responsible for designs such as Mies van der Rohe, Marcel Breuer, Eero Saarinen and Harry Bertoia. At the beginning of the 1960s, after a season in the company headquarters, he was indicated to share his knowledge on the field with the recently licensed Forma store in São Paulo. In Brazil, he not only disseminated the Bauhaus design, through his pioneering store – Inter/design – but also developed a method for decoration and interiors based on modern strategy and his own cultural background. Its architectural production, rooted in Mexican tradition, acculturated by international modernism and implanted in Brazilian territory, certainly deserves to be analyzed and thought. The presence of Aurelio Martinez Flores in Brazilian architecture, although unknown, is one of the most relevant to contemporaneity. Therefore, even if late, from the analysis of primary sources, this research is fundamental to announce one of the rare incursions between the two Latin American cultures.

O crime de desacato e o pacto de San José da Costa Rica

Pretende-se neste trabalho demonstrar a incompatibilidade material presente na legislação ordinária, que, aqui, estará representada pelo Código Penal vigente, tendo como contraponto do conflito antinômico a Convenção Americana de Direitos Humanos (Pacto de San José da Costa Rica), reconhecendo-se à controvérsia uma evidente inconstitucionalidade. A Corte Interamericana de Direitos Humanos já se manifestou ser contrária ao tipo penal de desacato, previsto no direito interno brasileiro, por sua desconformidade com o tratado interamericano, sendo, portanto, necessária a realização de verdadeiro Controle de Convencionalidade pelo Poder Judiciário, imprescindível de um Estado Democrático de Direito. O presente trabalho abordará acerca da análise subjetiva e objetiva do tipo penal de desacato, bem como da análise da Convenção Americana de Direitos Humanos (Pacto de San José da Costa Rica) e de seus dispositivos sob a luz da Constituição Federal Brasileira de 1988.

Garrincha, um filme de pernas tortas

Purpose: This dissertation begins with Joaquim Pedro de Andrade's cinematographic trajectory, his first experiences in cinema with the short films O Mestre de Apipucos (1959), O Poeta do Castelo (1959) and Couro de Gato (1960), relying in particular on the feature film Garrincha, Alegria do Povo (1963), with the intention of pointing out some important issues of the genre known as "documentary", as the film has been termed, showing its similarities with other genres of cinema. From an analysis of the use of impure footage in Garrincha, which was elaborated with the mixture of archival and filmed footage – an unusual practice at the time –, the dissertation draws similarities and differences with a supposed film genre, recently known as "filme-ensaio". For comparative purposes, an analysis of the documentary Rei Pelé, also from 1963, was carried out. Garrincha, Alegria do Povo reveals itself a singular film realized with practices similar to the filmic montages of works of the contemporary art.

O direito ao esquecimento na internet no contexto das decisões judiciais no Brasil

The technological advance of the last decades has brought new paradigms for a new kind of society: the information society. The constant use of the World Wide Web, the fluidity in the placement of information and data, and the permanent feeling of electronic surveillance contributed to rethink the Law and its applicability. If it was possible to separate the actuation of the individual in the public space and in the private space, today, with the pervasiveness of information, acting on such spaces is confused, making it impossible to establish a traditional privacy protection. It’s necessary to think about privacy as how the subject wants to be reminded or known in society as a right to oblivion. In this scenario, the idea of right to oblivion on the Internet appeared supported by leading European foreign cases (cases “Lebach” and “Mario Costeja”), together with the European Union directives that ensured the protection of sensitive and personal data to those involved. In Brazil, there isn’t legal provision of the institute, and despite the efforts made by the Judiciary in an attempt to resolve the matter in important cases, such as cases “Aída Curi” (Resp. n. 1.335.153/RJ), “Slaughter of Candelária” (Resp. n. 1.334.097/RJ) and “Xuxa versus Google” (Process n. 0024717-80.2010.8.19.0209), the foundations presented were insufficient for its application. Besides the lack of technical and specific knowledge of the Judiciary in dealing with the matter, another two factors must be considered: the functioning of the information society and the power of surveillance that the State exercises over individuals. These arguments, added to the manipulation of the legal rules to legalize violations and to the relativization speech of rights at the expense of national security and protective barriers, undermine democracy and, therefore, put away the application of the right to oblivion on the Internet, featuring, also, an exception state.

O trágico Jesus Cristo de José Saramago

The present work tried to demonstrate that the novel O Evangelho segundo Jesus Cristo (The Gospel according to Jesus Christ), written by José Saramago, may be interpreted as a tragic vision of Jesus´ figure. It searches to pursue the concept of the classical and modern tragedy and the character of the hero, as well. The novel is involved by Saragamo`s Marxist conception of the world. He is interested in rescuing the human nature of Jesus and refutes his divinity. In the beginning of the novel Saramago points Jesus in search of his real nature whether he is a man or a god but according Saramago´s point of view Jesus´ humanity is the fundamental trace of his life.

Da página do livro à tela do computador: um percurso histórico para a poesia infantil

At this work, we try to design a fast historical course of the Brazilian poetry for children, considering its publication since the end of the nineteenth century until the poetics constructions that could become concrete with the popularization of the computers and the internet: the ciberpoems. At first, we made a panoram that tries to suggest some significant changes the new techonologies brought to literature, especially to the relations that involve three elements that constitutes a literary system according to a social view of literature supported by Antonio Candido: writer, text and public. Following, through a historical course of poetry, we expose some aspects better evidenced on ciberpoems that had already been found in texts of different times and styles: visuality, sonority, movement and sinestesy. Finally, through the investigation of the historical of Brazilian literature for children, we present a fast analyse of Sérgio Capparelli s poems, writer who demonstrates in his work the transition of poetry between books and screens, showing the harmonic convivention between both that we are trying to suggest.
