Photoionization cross-sections out of the fine-structure levels (2S(2)2p(4) P-3(2,0,1)) of the O-like Fe ion Fe XIX have been reinvestigated. Data for photoionization out of each of these finestructure levels have been obtained, where the calculations have been performed with and without the inclusion of radiation damping on the resonance structure in order to assess the importance of this process. Recombination rate coefficients are determined using the Milne relation, for the case of an electron recombining with N-like Fe ions (Fe XX) in the ground state to form O-like Fe (Fe XIX) existing in each of the fine- structure ground-state levels. Recombination rates are presented over a temperature range similar to 4.0 less than or equal to log T-e less than or equal to 7.0, of importance to the modelling of X-ray emission plasmas.

We report calculations of energy levels, radiative rates and electron impact excitation cross<br/>sections and rates for transitions in He-like Cl XVI, K XVIII, Ca XIX and Sc XX. The grasp<br/>(general-purpose relativistic atomic structure package) is adopted for calculating energy levels<br/>and radiative rates. To determine the collision strengths and subsequently the excitation rates,<br/>the Dirac atomic R-matrix code (darc) is used. Oscillator strengths, radiative rates and line<br/>strengths are reported for all E1, E2, M1 and M2 transitions among the lowest 49 levels of<br/>each ion. Collision strengths are averaged over a Maxwellian velocity distribution and the<br/>effective collision strengths obtained listed over a wide temperature range up to 107.4 K.<br/>Comparisons are made with similar data obtained from the flexible atomic code (fac) to<br/>highlight the importance of resonances, included in calculations with darc, in the<br/>determination of effective collision strengths. Discrepancies between the collision strengths<br/>from darc and fac, particularly for forbidden transitions, are also discussed. Additionally,<br/>theoretical lifetimes are listed for all the 49 levels of the above four ions.

The diachronic studies marked the first decades of the 20th century in Brazilian linguistics, passing by an ostracism period after the 50s. Mainly from the 90s especially with the project, created in 1997, Para a história do português brasileiro (PHPB), which has systemized, in national ambit, the programme related to the area of diachrony the historical studies retake forces and have gradually increased since then. Our work is set in the new scene of Brazilian historical linguistics and it is associated to two research programmes: i) the constitution of a diachronic corpus; ii) the diachrony of text and discourse. As regards the first programme, we made effort to constitute a diachronic corpus of official letters about Rio Grande do Norte, we called cartas oficiais norte-rio-grandenses, written in 18th, 19th and 20th centuries. The chosen for bureaucrat letters occurred for they represent a textual category very productive in historical contexts, mostly 18th and 19th centuries, in which the command of writing was the least and also because they bring, almost always explicitly, the information of where, when, for whom and from whom, as remembers Fonseca (2003). The rules for constituting the corpus were based, although not strictly, on the orientation from PHPB. In respect to the second programme, we set up on the ideas of coserian base came from the studies on discourse traditions (TD) (Koch, 1997; Kabatek, 2006) amongst which that the texts are shaped so as to follow their own tradition (Coseriu, 2007), and we turned to Diplomatics (Belloto, 2002) in order to do the characterization of this corpus by the application of concepts from Diplomatics and TD as well as by the presentation of the structures that form those official letters: their textual genres, a kind of TD, with their macrostructures; and some of their formulaic expressions (microstructures), another sort of TD. This stage of characterizing will pay attention, as far as possible, to the dynamic between tradition and innovation that happen in the actualization of those textual structures along the centuries. This work intends to contribute with the researches connected to Historical Linguistics in Rio Grande do Norte, more specifically the ones related to the constitution of diachronic corpora and to TD; and with the study of official documents, textual category about which there are almost no studies (cf. Silveira, 2007)

This dissertation is a research on the marked topic construction (CT) in Brazilian personal letters from eighteenth, nineteenth and twentieth centuries. The goal of our research is to verify if CT are present in the writing of Brazilians born in the centuries in question. Our research focus is based on the assumptions of generative theory (CHOMSKY 1981; 1986), which states that grammar is internalized in the mind / brain of the writers, with the emphasis on studies of grammatical change, as pointed texts by Paixão de Sousa (2004), Carneiro (2005); Galves, Namiuti and Paixão de Sousa (2006) and Martins (2009). Our corpus was extracted from Projeto Para a História do Português Brasileiro (PHPB) and Cartas Brasileiras coletânea de fontes para o estudo do português. We selected forty-six correspondents who should be inserted into the two criteria set out in this research: to be Brazilian and be born in the centuries mentioned above, so that we could find legitimate topic constructions of PB. This work is based on researches by Pontes (1987), Mateus et al. (2003), Araujo (2006, 2009), Berlinck, Duarte and Oliveira (2009), which actively support us in the study of this linguistic phenomenon in Portuguese. The results show that the marked topic construction in our corpus appear on the writing of Brazilians since the second half of the eighteenth century, while the typical constructions in Brazilian Portuguese locative topic, subject topic and copy topic - are already reflected in the I-language of the writers born in the second half of the nineteenth century and the first of the twentieth century

O texto discute os muitos significados dados à morte de duas mulheres dos grupos menos abastados em Belém do Pará. Tais mulheres foram assassinadas em momentos distintos e tiveram a história de suas vidas e de suas mortes evocada por literatos, estudiosos da região e na imprensa paraense, como um exemplo a ser seguido por outras mulheres, revelando ideais de fidelidade, casamento, de famÃlia, entre outros. Se ainda hoje a força dessas histórias vem à tona com significados diversos, no passado não foi diferente sugerindo os muitos sentidos dados a suas vidas e a suas mortes.

In order to accomplish this article, it was necessary to schematize and to problematize how child/childhood concept along the centuries made their use possible by specialized speeches (namely: medical and pedagogic, mainly) in many different historical extracts. Looking at child/childhood, examining them, transforming them into knowledge and tutor bodies/object, countless attempts in disciplining their gestures and consequent institution of subjective processes will be some steep lines in this article. That will be done in order to evidence the existence of what is nowadays so called child/childhood, and that today is the target of specialists’ speeches that, in our analysis, when leaning over childhood, would dictate norms behavior for the children, limiting them and restricting them.

A tese examina a relação entre as elites e a educação em Portugal durante a Monarquia Constitucional e na Iª República. Em primeiro lugar caracteriza o quadro europeu no qual emergiram os modernos sistemas de ensino, focando-se depois na análise dos processos de segmentação que separaram o ensino clássico do ensino técnico, passando em revista a literatura sobre o reformismo educativo português. Em segundo, analisa o processo de segmentação na cidade de Évora, capital de uma região caracterizada pela prática de uma agricultura essencialmente extensiva e comercial, na qual estavam implantadas as instituições de ensino que constituem o objeto de estudo: o Liceu e a Escola Industrial. Em terceiro, procede à caracterização dos espaços escolares; em quarto estuda as condutas públicas dos agentes educativos, em particular dos reitores e dos professores, colocando em destaque a sua intervenção pública; em quinto, caracteriza a procura a que foram sujeitos os vários institutos de ensino estudados: a ênfase foi colocada na mobilidade geográfica aferida a partir da naturalidade dos alunos e da residência dos pais; em sexto, foi efetuada a análise da extração social dos alunos e o perfil ocupacional dos pais. Finalmente, em último lugar, foram reconstituÃdos os percursos académicos e profissionais dos alunos liceais no arco cronológico antes enunciado; Elites and Education.School itineraries and career paths.Alentejo, 19th and 20th centuries. Abstract: The thesis examines the relation between elites and education in Portugal, during the Constitutional Monarchy and the First Republic. Firstly, it characterises the European context in which modern teaching systems emerged and it focuses on the analysis of the processes of segmentation that separate classic and technical teaching. It reviews literature on Portuguese educational reformism, centred on classic and technical teaching. Secondly, it analyses the process of segmentation in Évora, capital of a region that is characterised by agriculture, which is essentially extensive and commercial, home to the education institutions our study focuses on: the Liceu and the Industrial School. Thirdly, school facilities are characterised; then, public behaviour of educators, namely that of headmasters and teachers, highlighting their public intervention; it characterises the demand in these institutions - the emphasis is placed on geographic mobility, considering students' birthplace and their parents' residence; a study on students' backgrounds and parents' occupational profiles is carried out. Eventually, the academic and professional itineraries of Liceu students' are reconstituted, within the formerly described chronological arch.

Resumen: Los avances del liberalismo conmovieron, en buena medida, a la filosofÃa cristiana. Efectivamente él consagró el valor de la libertad como aspiración máxima y, en su nombre, se intentó sacudir el yugo de la autoridad y la Iglesia no quedó al margen, por lo que los católicos se replantearon muchas de sus posiciones, a fin de poder brindar las respuestas sociales que la sociedad estaba reclamando. Fue asà que apareció la tercera escolástica, concebida como un movimiento de renovación contra el liberalismo que lo habÃa invadido todo. Los propulsores de esta corriente decidieron restaurar en las escuelas y universidades la filosofÃa de Santo Tomás. La Argentina sufrió también las embestidas del liberalismo, lo que impulsó a los católicos a prepararse para plasmar soluciones en las más diversas áreas, con la idea de fondo de imponer el catolicismo como el principio organizador del medio social, argumentando que esa habÃa sido la tendencia histórica en el paÃs. Asà fue como la tercera renovación escolástica, o neotomismo, penetró en la Argentina a fines del siglo XIX y en el XX, y se impuso tanto entre los seminaristas como en la Universidad de Córdoba y particularmente en su Facultad de Derecho y Ciencias Sociales. Durante los últimos años del otoño decimonónico la neoescolástica estuvo presente en muchas de las tesis presentadas en la Facultad de Derecho, siguiendo, en este aspecto, una tradición de la universidad cordobesa, la que predominaba también entre ciertos profesores. En este trabajo rastreamos los fundamentos del poder polÃtico que se encuentran en esos trabajos, refiriéndonos, por un lado, a la visión del grupo sobre el orden, a la igualdad y el progreso y, por otro, a los derechos del hombre.
