Decisão política no Estado Novo, 1933-1939

Os processos de decisão política em regimes não democráticos têm sido objecto de um interesse crescente, quer em relação às ditaduras do período entre guerras, quer no âmbito dos chamados «novos autoritarismos ». Os estudos sobre as elites assentam na ideia de que o seu perfil constitui um factor determinante na distribuição do poder (Rees 2005; Almeida, Pinto e Bermeo 2006). Já os estudos centrados nas instituições defendem que as regras de funcionamento das estruturas de poder são uma fonte fundamental para a compreensão do processo decisório (Gandhi 2008). Por fim, a investigação sobre os tipos de liderança tem sustentado a ideia de que o processo de decisão política pode ser entendido com base no aspecto carismático, burocrático-legal e tradicional do líder (Pinto, Eatwell e Larsen 2007; Kershaw 2009). Sendo a centralização do poder uma das variáveis de estudo do processo de decisão política, dificilmente será captada pela análise isolada de cada um desses aspectos. Pelo contrário, as variáveis da centralização e da decisão política devem ser tratadas articulando a investigação do funcionamento das instituições, da natureza das elites e do tipo de liderança do ditador. Procurando pôr em prática esta ideia, estuda-se aqui a centralização do poder político em Portugal durante o período de institucionalização do Estado Novo (1933-1939), explorando simultaneamente as dimensões formais e informais da decisão política. Analisa-se, em particular, o papel do Conselho de Ministros, já que certos estudos publicados ao longo das últimas décadas sugerem que Salazar desvalorizou substancialmente este órgão, contrariamente ao que sucedeu durante os anos que antecederam e sucederam ao salazarismo – ou seja, na ditadura militar (1926-1933) e no marcelismo (1968-1974).

A arqueologia mineira: território interdisciplinar

A mina do Lousal encerrou os trabalhos em 31 de Maio de 1988 após menos de cem anos de laboração.Quase dez anos depois desta data teve início um processo tendente a regenerar o tecido social e económico do Lousal e a promover a recuperação ambiental da área mineira.Com efeito, todos sabemos que naqueles locais em que uma única actividade económica contribuiu durante muito tempo para sustentar em exclusivo o desen-volvimento locai, quando ela cessa fica um território deprimido dos pontos de vista social e económico c também ambiental no caso das explorações mineiras.Isso mesmo foi o que sucedeu no Lousal.O processo de recuperação que acima referimos tem como base e motor do novo ciclo de vida do Lousal um Museu Mineiro - o mesmo é dizer, o património geológico e mineiro c a história local.

A gênese e a estrutura do serviço social brasileiro no período doutrinário católico

Esta tese examina os textos sobre a história do Serviço Social Latino-Americano e Brasileiro questionando as generalizações formuladas. Mostra-se que não está de todo clara a caracterização e a explicação da gênese e do processo de estruturação do Serviço Social Brasileiro. Com base na metodologia de Lucien Goldmann foram estudados os textos produzidos pelos primeiros assistentes sociais brasileiros até dezembro de 1947, ano de realização do I Congresso Brasileiro de Serviço Social. Identificou-se sete autores significativos, isto é, que expressavam a maior coerência em relação à visão social de mundo contida na totalidade do material produzido. A partir dos autores significativos e, com base na Doutrina Social da Igreja católica, identificou-se a estrutura de visão social de mundo assumida pelos mesmos. Foram analizados os aspectos do homem, da família, da educação, da sociedade, do estado, do governo e do direito e justiça social. Todos se estruturam dentro da perspectiva denominada Democracia Cristã. Da mesma forma foram examinados os conceitos, finalidades, a ação e a formação profissional do assistente social no período. Especial atenção foi dada à discussão: Serviço Social - profissão ou apostolado. Identificou-se alguns pontos divergentes entre os autores, o que prova que a homogeneidade atríbuida aos mesmos não corresponde à realidade constatada.

Formação de professores, saberes, reflexividade e apropriação da cultura digital no Projeto Um Computador por Aluno (UCA)

This study investigates teacher training and cognitive practice of teachers in a Basic Education school that adopted the Project One Computer per Student (OCS) in their school routine. Its relevance consists in provide directions for the continuation of training activities on the Project and guide the teachers with their pedagogical practices using the laptop model one to one. The thesis defended is that the educator formation for social using of digital media (specially the laptops from the Project UCA) gives space to establish new sociotechnical relationships, of new social and professionals practices, new identitary components and a process of reflexivity and knowledge reconstruction to teach. We reaffirm the importance of reflexivity and appropriation of digital culture for the better development of teaching practice using the Information and Communication Technologies (ICTs), giving focus to the aspects of social and professional use of the technology. The study is part of the qualitative aspect and is a procedural tracking based on principles of ethnographic research. As procedures and methodological tools, were used: intensive observation of school environments, documental analysis, focal group, semi-structured questionnaires and semi-structured individual interviews. The research was held in a public school in the city of Parnamirim - RN. The subject sample relates to 17 teachers, coming from the elementary school I and II, Youth and Adult Education and High School, who went through the process of training UCA and having entered the laptops in their teaching. The research corpus is structured based on the messages built into the process of data collection and is analyzed based on principles of Content Analysis, specified by Laurence Bardin (2011). Was taken as theoretical reference studies by Tardif (2000; 2011), Pimenta (2009), Gorz (2004, 2005), Giddens (1991), Dewey, J. (1916), Boudieu (1994; 1999), Freire (1996; 2005), among others. The analysis indicates a process of reconstruction / revision of knowledge to teach and work in digital culture, being these knowledges guided by the experience of the subjects investigated. The reconstructed knowledges will be revealed from a categorization process. The following groups of knowledges: "technical knowledges", "didactic-methodological knowledges and knowledges of professionalization" were built on the assumption of ownership of digital culture in the educational context. The analysis confirms the appearance of new ways of sociability when acquiring other forms of acting and thinking ICTs, despite the environment adverse to the reflexivity shared among the teachers. Also reveals, based on the ownership concept present on the data analysis, the construction of meanings of belonging and transformation of individuals into social routes from the interweaving of the teaching practice with the digital culture. Emphasizes, finally, the importance of a training for use of ICTs that exceeds the instrumentation, in other words, what we call "technical knowledges", but taking on its structural basis the shared reflection, the opening for the ressignificance (new meaning) and reconstruction of new knowledges and practices and that really allows, to the teacher, the living of an experience capable of providing socio-technical transformations of their relationships

Estrutura genética de populações de melhoramento de Pinus caribaea var. Hondurensis por meio de marcadores microssatélites

O Pinus caribaea var. hondurensis Barret & Golfari tem elevada importância como espécie comercialmente plantada; aproximadamente 1,8 milhões de hectares estão ocupados por plantios desta espécie no Brasil. O trabalho teve como objetivo verificar por meio de marcadores microssatélites a variabilidade genética em Pinus caribaea var. hondurensis, bem como sua manutenção durante o processo de melhoramento genético, dentro de uma população- base de melhoramento, uma população de matrizes selecionadas e uma população melhorada F1. Para a realização das análises foi necessária a transferência de primers desenvolvidos para locos microssatélites de outras espécies do gênero. Dos 20 pares de primers testados, 8 foram transferidos para a espécie (RPS 25b, RPS 150, PSM 2, PR 4.6, PtTX 2037, PtTX 3029, RPTest 01 e RPTest 09). Verificou-se a existência de endogamia entre e dentro das populações estudadas, e o maior valor observado entre as populações foi F ST = 0,0213 (população base e F1). A heterozigosidade média observada e a heterozigosidade esperada na população-base foram, respectivamente, H0 = 0,2469 e He = 0,2489. A maior distância genética (D = 0,0119) foi observada entre as populações-base e a população melhorada F1. Através da distância genética entre as matrizes, foram indicados 10 cruzamentos potenciais entre as matrizes mais contrastantes, almejando a obtenção de vigor de híbrido nas progênies obtidas a partir destes cruzamentos.

Estratégias argumentativas na construção do discurso ideológico: um estudo da produção didático-pedagógica do meb

This research studies the argumentative process developed by the Basis Educational Movement (MEB), using as corpus the booklet Viver é lutar , and other lesson plans of the Educational Rural Radio from Natal. It has as objectives reveal the argumentative strategies in the discursive production of MEB, exploring the meaning effects suggested by its production conditions, and the ideological positions defended, in addition to this, verify how the booklet and the radio classes dialogued in the argumentation of their theses. So, the study is guided by the Discourse Analysis presuppositions, by the Argumentation Theory, by the conceptions of Popular Education, as well as the conception language dialogical language conception, recurring to Bakhtin (1995). The research adopts the documental characteristic of qualitative nature with an interpretative basis. The analysis of the data permitted us to confirm that the pedagogical didactic material discourse of MEB was produced in a social-historical-ideological context in what the education was seen as a social liberation instrument, being able to transform the Brazilian people and the Brazilian unequal structure. The results reveal that the booklet and the classes assume a position remarkably in favor of the popular classes, structured by the argumentative techniques that intended to convince, and to persuade the auditorium. Thus, the argument was based initially on the convincing of youths and of adults for, afterwards, to construct a persuasion to the learners, in terms of referring to act on the reality to transform it, according to their desires of social justice

Trajetória de carreira do profissional de recursos humanos

The idea that the career consists in a linear path throughout the individual s professional life structured by the company where he or she works has been changing to a new reality in which the career is seen as a journey, open to possibilities and uncertainties. Several models have come up as an attempt to comprehend and analyze this journey. Among them, there is the model of career narrative, which assumes that, while narrating, individuals give meaning to their own path, and at the same time they consider personal factors and the environment that act on their professional biography. This paper aimed to explore and articulate issues related to the environment and career paths of the human resource professionals working in the Greater Natal. For this purpose, the model of career narrative was used. From the methodological viewpoint, the project was divided in two stages. The first was characterized by conducting a survey with the intention of mapping professionals socio-occupational characteristics, through the application of a semi-structured questionnaire. The data was analyzed by descriptive statistical techniques and cluster analysis. The descriptive statistical analyses included 117 participants. The results indicated that HR professionals of Greater Natal have different functions, develop activities focused on different subsystems, have an increasing career path, and focus their professional formation in Business Administration and Psychology. The second stage of the study was characterized by the use of 17 narrative interviews, whose participants, in the process of nonprobabilistic sampling, were identified based on their belonging to the three clusters: Group 1, HR and public administration; Group 2, HR experts; and Group 3, HR beginners. Analyzing the results of the qualitative phase, it was found that the identification with the activity practiced is a deciding factor for choosing and remaining in the HR field. The lack of professional recognition appears as the main difficulty faced by professionals, as well as the lack of employment opportunity in the Greater Natal. The results analysis leads to a series of discussions on the career path in HR and reflections for this professional category, its representative bodies and educational institutions

Tratamento eletroquímico de água produzida sintética para remoção de hidrocarbonetos policíclicos aromáticos

The aim of this work is the treatment of produced water from oil by using electrochemical technology. Produced water is a major waste generated during the process of exploration and production in the oil industry. Several approaches are being studied aiming at the treatment of this effluent; among them can be cited the biological process and chemical treatments such as advanced oxidation process and electrochemical treatments (electrooxidation, electroflotation, electrocoagulation, electrocoagulation). This work studies the application of electrochemical technology in the treatment of the synthetic produced water effluent through the action of the electron, in order to remove or transform the toxic and harmful substances from the environment by redox reactions in less toxic substances. For this reason, we used a synthetic wastewater, containing a mixture H2SO4 0,5M and 16 HPAs, which are: naphthalene, acenaphthylene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene, benzo (a) anthracene, chrysene, benzo(b)fluoranthene, benzo(k) fluoranthene, benzo(a)pyrene, indeno(1,2,3-cd)pyrene, dibenzo(a, h)anthracene, benzo(g, h, i)perylene. Bulk electrochemical oxidation experiments were performed using a batch electrochemical reactor containing a pair of parallel electrodes, coupled with a power supply using a magnetic stirrer for favoring the transfer mass control. As anodic material was used, a Dimensionally Stable Anode (DSA) of Ti/Pt, while as cathode was used a Ti electrode. Several samples were collected at specific times and after that, the analysis of these samples were carried out by using Gas Chromatography Coupled to Mass Spectrometry (GC - MS) in order to determine the percentage of removal. The results showed that it was possible to achieve the removal of HPAs about 80% (in some cases, more than 80%). In addition, as an indicator of the economic feasibility of electrochemical treatment the energy consumption was analyzed for each hour of electrolysis, and based on the value kWh charged by ANEEL, the costs were estimated. Thus, the treatment costs of this research were quite attractive

O meteorito condrítico Saulo Gomes

This paper aims to present the results of petrographic and lithochemical studies obtained in one of the three artifacts, which fell on the farm Buritis in Buritizal County in August 1967, which were collected and stored until the present by reporter Saulo Gomes. The petrographic analysis showed that the artifact is composed by spherical and irregular chondrules with serial granulometry and size averaging around 1 mm and the largest reaching about 6 mm in diameter. The chondrules are made of olivine, ortho and clinopyroxene, crystallite glass, nickel iron alloy and troillite (kamacite and/or taenite/tetrataenite) and inter chondrules glassy material occurs in association with troillite, nickel and other alloy iron-based compounds. The lithochemical data show excellent correlation with the C chondrite, noting only small differences above or between them. The study made it possible to classify the artifact as type L3 and L4 ordinary chondrite.

Delineation of specific management areas for coffee cultivation based on the soil-relief relationship and numerical classification

Predicting and mapping productivity areas allows crop producers to improve their planning of agricultural activities. The primary aims of this work were the identification and mapping of specific management areas allowing coffee bean quality to be predicted from soil attributes and their relationships to relief. The study area was located in the Southeast of the Minas Gerais state, Brazil. A grid containing a total of 145 uniformly spaced nodes 50 m apart was established over an area of 31. 7 ha from which samples were collected at depths of 0. 00-0. 20 m in order to determine physical and chemical attributes of the soil. These data were analysed in conjunction with plant attributes including production, proportion of beans retained by different sieves and drink quality. The results of principal component analysis (PCA) in combination with geostatistical data showed the attributes clay content and available iron to be the best choices for identifying four crop production environments. Environment A, which exhibited high clay and available iron contents, and low pH and base saturation, was that providing the highest yield (30. 4l ha-1) and best coffee beverage quality (61 sacks ha-1). Based on the results, we believe that multivariate analysis, geostatistics and the soil-relief relationships contained in the digital elevation model (DEM) can be effectively used in combination for the hybrid mapping of areas of varying suitability for coffee production. © 2012 Springer Science+Business Media New York.
