Circulação de textos midiáticos entre alunos de escola pública básica

The text characterizes the reading of media-related materials by students of the public basic education system in the State of São Paulo, based on a systematic observation of the circulation of press texts within the school daily life. In a study carried out during two academic years with groups of students from fundamental and secondary education classes belonging to two different schools situated in the outskirts of a town in the interior of the state, the students' reports on their appropriation of media-based information obtained from a variety of sources were analyzed, with particular emphasis on written newspapers. During the period investigated individual and group interviews, as well as texts produced by the students, were taken as points of departure for the analysis. Among the aspects noted from the contact with communication media is the establishment of press information inside the school, albeit with fragmentary repercussions, not fully integrated into the pedagogical daily life, but somewhat circumstantial in the students' lives. The themes that receive more attention circulate through the television, mediated by family or peers, but not by teachers. A proposal for the analysis of these data is made, followed by concrete suggestions as to the treatment to be given to support material, texts and media-based issues at school, taking into account the resources available and the school context such as it appears nowadays.

Os antecedentes e a luta atual em torno da Conferência Nacional de Comunicação

The ancient struggle for a National Conference on Communication in Brazil, truly representative and with clear opportunities to define new rules to the sector of communication, has been waged for years and was conducted in late 2009. It is proposed to identify the background of the historic struggle for CNC can be perceived in the defense of press freedom and freedom of expression in seventeenth and eighteenth centuries, most recently in the movements of democratization policy in the 80s and 90s. The research was done by analyzing the direct and indirect official document concerning the establishment of guidelines and the convening of the Conference, and manifestation of civil society and business. 


Efeitos do conhecimento de resultados autocontrolado na aprendizagem motora

O objetivo do presente estudo foi analisar três diferentes estratégias de fornecer conhecimento de resultados (CR): autocontrolado, yoked pareado por tentativa e yoked pareado pela frequência média total de CR, na prática aleatória. A amostra foi constituída por 45 voluntários universitários, distribuídos em três grupos (n= 15 sujeitos). A tarefa consistiu em pressionar as teclas 2, 4, 8 e 6 do teclado numérico de um computador, em três diferentes tempos alvo (700, 900 e 1100 ms), praticados aleatoriamente. O experimento constou de fase de aquisição e testes de retenção e transferência atrasados. A análise dos dados foi realizada por meio da ANOVA e não foi constatada diferença significativa entre os grupos. Os resultados demonstraram que não houve efeito das frequências autocontroladas para a aprendizagem motora quando se utiliza a prática aleatória. Além disso, uma nova possibilidade de parear o grupo autocontrolado foi apresentada.

O Estado Novo e as críticas a Machado de Assis na primeira metade dos anos 1940

Este artigo tem como objetivo analisar o tratamento conferido pelo Estado Novo brasileiro (1937-1945) a Machado de Assis, depois das celebrações oficiais do centenário do autor de Dom Casmurro em 1939. Se, no ano da efeméride, o governo se empenhou em alçar o romancista à condição de maior escritor brasileiro, no início dos anos 1940, no âmbito do Departamento de Imprensa e Propaganda (DIP), o tom passa a ser outro: num contexto de prevalência de certo caráter social e documental da obra de arte, o próprio Getúlio Vargas, o ideólogo Cassiano Ricardo e os principais periódicos estadonovistas fazem menção ao suposto absenteísmo e à falta de "cor local" do fundador da Academia Brasileira de Letras.

Primary stability in cementless total hip replacement: measurement techniques and aided-surgery

Primary stability of stems in cementless total hip replacements is recognized to play a critical role for long-term survival and thus for the success of the overall surgical procedure. In Literature, several studies addressed this important issue. Different approaches have been explored aiming to evaluate the extent of stability achieved during surgery. Some of these are in-vitro protocols while other tools are coinceived for the post-operative assessment of prosthesis migration relative to the host bone. In vitro protocols reported in the literature are not exportable to the operating room. Anyway most of them show a good overall accuracy. The RSA, EBRA and the radiographic analysis are currently used to check the healing process of the implanted femur at different follow-ups, evaluating implant migration, occurance of bone resorption or osteolysis at the interface. These methods are important for follow up and clinical study but do not assist the surgeon during implantation. At the time I started my Ph.D Study in Bioengineering, only one study had been undertaken to measure stability intra-operatively. No follow-up was presented to describe further results obtained with that device. In this scenario, it was believed that an instrument that could measure intra-operatively the stability achieved by an implanted stem would consistently improve the rate of success. This instrument should be accurate and should give to the surgeon during implantation a quick answer concerning the stability of the implanted stem. With this aim, an intra-operative device was designed, developed and validated. The device is meant to help the surgeon to decide how much to press-fit the implant. It is essentially made of a torsional load cell, able to measure the extent of torque applied by the surgeon to test primary stability, an angular sensor that measure the relative angular displacement between stem and femur, a rigid connector that enable connecting the device to the stem, and all the electronics for signals conditioning. The device was successfully validated in-vitro, showing a good overall accuracy in discriminating stable from unstable implants. Repeatability tests showed that the device was reliable. A calibration procedure was then performed in order to convert the angular readout into a linear displacement measurement, which is an information clinically relevant and simple to read in real-time by the surgeon. The second study reported in my thesis, concerns the evaluation of the possibility to have predictive information regarding the primary stability of a cementless stem, by measuring the micromotion of the last rasp used by the surgeon to prepare the femoral canal. This information would be really useful to the surgeon, who could check prior to the implantation process if the planned stem size can achieve a sufficient degree of primary stability, under optimal press fitting conditions. An intra-operative tool was developed to this aim. It was derived from a previously validated device, which was adapted for the specific purpose. The device is able to measure the relative micromotion between the femur and the rasp, when a torsional load is applied. An in-vitro protocol was developed and validated on both composite and cadaveric specimens. High correlation was observed between one of the parameters extracted form the acquisitions made on the rasp and the stability of the corresponding stem, when optimally press-fitted by the surgeon. After tuning in-vitro the protocol as in a closed loop, verification was made on two hip patients, confirming the results obtained in-vitro and highlighting the independence of the rasp indicator from the bone quality, anatomy and preserving conditions of the tested specimens, and from the sharpening of the rasp blades. The third study is related to an approach that have been recently explored in the orthopaedic community, but that was already in use in other scientific fields. It is based on the vibration analysis technique. This method has been successfully used to investigate the mechanical properties of the bone and its application to evaluate the extent of fixation of dental implants has been explored, even if its validity in this field is still under discussion. Several studies have been published recently on the stability assessment of hip implants by vibration analysis. The aim of the reported study was to develop and validate a prototype device based on the vibration analysis technique to measure intra-operatively the extent of implant stability. The expected advantages of a vibration-based device are easier clinical use, smaller dimensions and minor overall cost with respect to other devices based on direct micromotion measurement. The prototype developed consists of a piezoelectric exciter connected to the stem and an accelerometer attached to the femur. Preliminary tests were performed on four composite femurs implanted with a conventional stem. The results showed that the input signal was repeatable and the output could be recorded accurately. The fourth study concerns the application of the device based on the vibration analysis technique to several cases, considering both composite and cadaveric specimens. Different degrees of bone quality were tested, as well as different femur anatomies and several levels of press-fitting were considered. The aim of the study was to verify if it is possible to discriminate between stable and quasi-stable implants, because this is the most challenging detection for the surgeon in the operation room. Moreover, it was possible to validate the measurement protocol by comparing the results of the acquisitions made with the vibration-based tool to two reference measurements made by means of a validated technique, and a validated device. The results highlighted that the most sensitive parameter to stability is the shift in resonance frequency of the stem-bone system, showing high correlation with residual micromotion on all the tested specimens. Thus, it seems possible to discriminate between many levels of stability, from the grossly loosened implant, through the quasi-stable implants, to the definitely stable one. Finally, an additional study was performed on a different type of hip prosthesis, which has recently gained great interest thus becoming fairly popular in some countries in the last few years: the hip resurfacing prosthesis. The study was motivated by the following rationale: although bone-prosthesis micromotion is known to influence the stability of total hip replacement, its effect on the outcome of resurfacing implants has not been investigated in-vitro yet, but only clinically. Thus the work was aimed at verifying if it was possible to apply to the resurfacing prosthesis one of the intraoperative devices just validated for the measurement of the micromotion in the resurfacing implants. To do that, a preliminary study was performed in order to evaluate the extent of migration and the typical elastic movement for an epiphyseal prosthesis. An in-vitro procedure was developed to measure micromotions of resurfacing implants. This included a set of in-vitro loading scenarios that covers the range of directions covered by hip resultant forces in the most typical motor-tasks. The applicability of the protocol was assessed on two different commercial designs and on different head sizes. The repeatability and reproducibility were excellent (comparable to the best previously published protocols for standard cemented hip stems). Results showed that the procedure is accurate enough to detect micromotions of the order of few microns. The protocol proposed was thus completely validated. The results of the study demonstrated that the application of an intra-operative device to the resurfacing implants is not necessary, as the typical micromovement associated to this type of prosthesis could be considered negligible and thus not critical for the stabilization process. Concluding, four intra-operative tools have been developed and fully validated during these three years of research activity. The use in the clinical setting was tested for one of the devices, which could be used right now by the surgeon to evaluate the degree of stability achieved through the press-fitting procedure. The tool adapted to be used on the rasp was a good predictor of the stability of the stem. Thus it could be useful for the surgeon while checking if the pre-operative planning was correct. The device based on the vibration technique showed great accuracy, small dimensions, and thus has a great potential to become an instrument appreciated by the surgeon. It still need a clinical evaluation, and must be industrialized as well. The in-vitro tool worked very well, and can be applied for assessing resurfacing implants pre-clinically.

Forecasting Intraday Stock Price Trends with Text Mining Techniques

In this paper, we describe NewsCATS (news categorization and trading system), a system implemented to predict stock price trends for the time immediately after the publication of press releases. NewsCATS consists mainly of three components. The first component retrieves relevant information from press releases through the application of text preprocessing techniques. The second component sorts the press releases into predefined categories. Finally, appropriate trading strategies are derived by the third component by means of the earlier categorization. The findings indicate that a categorization of press releases is able to provide additional information that can be used to forecast stock price trends, but that an adequate trading strategy is essential for the results of the categorization to be fully exploited.

How parties justified the 2014 EP election debate. A comparative analysis in six EU countries

On the role of parties as important channels for people to voice their preferences there is a sound consensus in the literature. Traditional socio-economic concerns have been more and more displaced by culturally fought issues such as immigration and European integration. Scholarly works, however, have paid less attention how, if at all, parties combine different cultural issues. The primary aim of the analysis is to investigate if and under which conditions parties link immigration and European integration issues to address the growing discontent in the population with these issues. Our expectation is that parties endorse different strategies depending on the party competition, in particular the presence of a populist challenger. The analysis is based on a quantitative content analysis of press releases and newspapers articles published in the 12 weeks preceding the 2014 EP election in five European countries (Austria, Germany, Greece, the Netherlands and the United Kingdom).

España Republicana, una lectura de la Guerra Civil desde Argentina

España Republicana fue el órgano de prensa del Centro Republicano Español de Buenos Aires que, entre 1918 y 1964, resultó un medio esencial para la comunicación de las noticias de España en materia política, cultural, económica y social. Además de constituir un ámbito de información, dio lugar al diálogo entre entidades españolas de la Argentina y sirvió como vehículo a la hora de reunir material de ayuda en los momentos más duros de la Guerra Civil y de la posguerra. En sus páginas, las personalidades más destacadas de la II República aparecen como protagonistas, con sus alocuciones citadas en discurso directo, en plena toma de decisiones y, muchas veces, como firmantes de colaboraciones dedicadas en exclusiva a ser publicadas en el periódico. Dada la importante función que cumplió España Republicana durante la Guerra Civil, hemos creído útil dar a conocer en este número mono-gráfico los detalles de un trabajo que formó parte de un amplio proyecto de investigación de archivos que desarrolla el Ministerio de Cultura español, en colaboración con la Fundación "Claudio Sánchez-Albornoz". En síntesis, la tarea consistió en la microfilmación y elaboración de un índice comentado de cada uno de los más de mil números disponibles de la publicación, con un detallado registro de contenidos, onomásticos e instituciones, entre otros aspectos considerados, a fin de facilitar a los investigadores de todo el mundo la localización de los datos de su interés.

The inverted Chinese / China problem in Indonesia : a preliminary analysis on the 2011 Surabaya incident

A clash between the police and journalists covering a Falun Gong gathering in Surabaya 2011 have shown a significant change in understanding the triangular relationship between Indonesia, China and the Ethnic Chinese in Indonesia. During the Suharto period, ethnic Chinese in Indonesia and China as a foreign state were the problems for the Indonesian government. After the political reforms in Indonesia together with the Rise of China in 2000s, in some situation, it is the Indonesian government together with the Chinese government which is the problem for some ethnic Chinese in Indonesia. Ethnic Chinese people were seen to be close with China and their loyalty to the nation was doubted. But now it is the Indonesian government which is viewed as being too close to China and thus harming national integrity, and suspected of being unnationalistic.

La censura del tema deportivo en la prensa durante la posguerra española (1939-1945)

La presente tesis doctoral pretende arrojar nueva luz sobre la utilización de la prensa durante los primeros años del franquismo. En concreto, el objetivo ha sido estudiar la censura del tema deportivo dentro del sistema censorio de los primeros años de posguerra civil en España, una área no estudiada hasta hoy y que entendemos fundamental para entender el desarrollo del deporte durante el llamado primer franquismo. Para ello, se estudiaron de manera pormenorizada los actores principales y los pasos básicos del proceso de censura; los métodos utilizados, tanto materiales como personales, para hacer efectiva ésta; y, por último, sus manifestaciones reales en el ámbito de la información deportiva: qué se censuró, por parte de quién, de qué forma y por qué motivos. De este modo, pretendemos llenar una de las lagunas de investigación que aún quedan dentro del estudio de la censura de prensa durante el franquismo. La metodología utilizada es la técnica historiográfica. Basado en el análisis crítico y en la interpretación de fuentes primarias, dicho método trata de establecer marcos históricos de referencia a través del estudio pormenorizado de las circunstancias del pasado. Ello implica una estructura algo distinta a la de las tesis doctorales de otras áreas de estudio puesto que, exceptuando la introducción, toda la tesis es la exposición de los resultados de la investigación llevada a cabo. Se ha utilizado cuantiosa documentación de los archivos General de la Administracion (Alcalá de Henares) y Centrale dello Stato (Roma) no manejada anteriormente por ningún investigador. La prensa periódica de la época y la legislación que afecta a nuestro tema de estudio también han sido ampliamente investigadas, tanto en el contexto español como en el italiano. Nuestra investigación arroja los siguientes resultados. Efectivamente, existió censura de prensa en el tema deportivo en las siguientes temáticas fundamentales: cuestiones económicas, autoridades y jerarquías, uso del lenguaje y comportamiento de los deportistas. En la mayor parte de los casos, la censura se ejerce en la información deportiva por razones ajenas al propio deporte. No se puede afirmar que existan diferencias en el tratamiento general entre medios de la Prensa del Movimiento y otros de titularidad privada o eclesiástica, si bien la aplicación de la censura no fue homogénea sino arbitraria en muchos casos. El sistema de censura de prensa español del primer franquismo toma la mayoría de sus rasgos del modelo fascista italiano, aunque tiene alguna característica propia como la censura previa y el catolicismo imperante. ABSTRACT This doctoral thesis aims to shed light on the use of press during the first years of francoism. The particular objective was to study the censorship of the sport topic into the general system of censorship carried out after the Spanish Civil War. It is a subject comparatively understudied to date but a key aspect to understand the development of sport during the so called early francoism. To this end, an in-depth study was made on key actors, main steps of censorship process, human and material methods used to ensure its effectiveness, and the actual manifestations in sports information area: what was censored, by whom, how and why. This should ensure us to fill the historiographical gap within the research on Francoʼs press censorship. Methodology used was historiographic research. It is based on critical analysis and interpretation of primary sources and seeks to establish historical reference frameworks tracing back the past in detail. It determines a different doctoral thesis structure in some aspects. Except the introduction, the whole document is the report and explanation of the results of research. A large amount of unexplored documents from the Archivo General de la Administración (Alcalá de Henares, Spain) and the Archivio Centrale dello Stato (Rome, Italy) has been used. The press of the period and legislation about our topic have also been analysed in detail both in Spain and Italy. Our research states these results. We can affirm that press censorship actually existed on sports topic in these thematic priorities: economical issues, authorities and hierarchies, use of language and sportsmen behaviours. In most cases, the censorship of sports information is exercised for reasons unconnected to sport. It cannot be concluded that general differences were applied in press censorship between State-owned media and private or church media although its implementation was non-uniform and arbitrary in many cases. The system of press censorship in Spain during the early francoism is clearly inspired by fascist Italy system copying most of its features although Spain had a few specific characteristics like prior censorship and catholicism.

GÊNESE DA IMPRENSA NO MARANHÃO NOS SÉCULOS XIX E XX

A imprensa brasileira nasceu tardiamente, 276 anos após o início da ocupação da colônia americana pela Coroa portuguesa. Investigando as singularidades desse processo na região Nordeste, pretende-se resgatar a gênese das atividades tipográficas no Maranhão, cujo marco é o jornal O Conciliador do Maranhão, que circulou entre novembro de 1821 e julho de 1823. O objetivo é identificar os fatores socioculturais que explicam o retardamento da imprensa no Estado. Para tanto, foi realizada uma pesquisa histórica adotando dupla estratégia metodológica: a) qualitativa: destinada a compreender as circunstâncias que contribuíram para delongar a chegada da imprensa à capital maranhense, condicionando a natureza da produção jornalística nascente; b) quantitativa: visando reconstituir o perfil jornalístico, a política editorial e a estrutura morfológica do jornal pioneiro, através da análise do conteúdo manifesto de uma amostra daquele periódico.(AU)
