Surface growth for molten silicon infiltration into carbon millimeter-sized channels: Lattice–Boltzmann simulations, experiments and models

The process of liquid silicon infiltration is investigated for channels with radii from 0.25 to 0.75 [mm] drilled in compact carbon preforms. The advantage of this setup is that the study of the phenomenon results to be simplified. For comparison purposes, attempts are made in order to work out a framework for evaluating the accuracy of simulations. The approach relies on dimensionless numbers involving the properties of the surface reaction. It turns out that complex hydrodynamic behavior derived from second Newton law can be made consistent with Lattice-Boltzmann simulations. The experiments give clear evidence that the growth of silicon carbide proceeds in two different stages and basic mechanisms are highlighted. Lattice-Boltzmann simulations prove to be an effective tool for the description of the growing phase. Namely, essential experimental constraints can be implemented. As a result, the existing models are useful to gain more insight on the process of reactive infiltration into porous media in the first stage of penetration, i.e. up to pore closure because of surface growth. A way allowing to implement the resistance from chemical reaction in Darcy law is also proposed.

Co-design: setting relational domains for deep sustainability

This paper draws mainly on the work of Elizabeth Sanders who has being practising, thinking and mapping participatory design research for over 25 years, connecting it to insights from Maturana (1984), Capra (2002), Jovchelovitch (1995, 2000, 2007) and Preece (2011), to propose that the process of design per se is a relational domain of cocreativity that is essential to construct a way toward deeper sustainability.

‘Neutral, native-like or authentic’ : Investigating attitudes and beliefs of expanding circle speakers of English

The status of English as the language of international communication is by now well-established. However, in the past 16 years, research has tried to emphasize the fact that the English spoken in international contact situations and between people with other first languages than English has different needs than the English spoken locally amongst native speakers, resulting in the emergence of English as a lingua franca (ELF) as a scholarly field. However, the impact of findings in ELF has so far only led to a moderate shift in English language teaching. Especially in expanding circle countries, where ELF should have the biggest impact, change is only gradually becoming palpable. Accent and pronunciation, as one of the biggest factors on both identity and mutual intelligibility (Jenkins 2000; 2007) are at the root of discussion. The scope of this study is therefore to examine accent choices and the extent to which native speaker ideology informs the preferences of ten speakers of ELF and 27 German natives with experience in international communication. Both ethnographical and sociolinguistic methods, as well as auditory analysis have been applied and conducted. The auditory analysis of six variables in the recorded speech production of the ten speakers suggests that there is no significant preference of one norm-giving variety over the other. Rather, speakers tend to mix-and-match General American- and Standard Southern British English-like features in their pronunciation. When reporting their accent ideals, the idea of a ‘neutral’ English accent is mentioned by four participants. Neutral accents seem to have been understood as ‘unmarked accents’. Expressed beliefs on their own English pronunciation show a comparatively high level of reflection on and confidence in their own production. Results from a rating task and a survey given to 27 German participants reveal attitudes that are more negatively stacked. While Germans reported openness towards NNS (non-native speaker) accents and showed awareness of the priority of intelligibility over accent choice in both their own and others’ pronunciation, they still largely reported NS accent preference. The ratings of the production from ten ELF speakers confirmed this and showed that ‘neutral’ is equated with native-like. In the light of these findings, issues are discussed that ultimately relate to the influence of NS Englishes, identity and the development of English as an international language.

Currículo escolar e inclusão de estudantes com deficiência: diálogos com uma escola pública

This work of qualitative approach, has as its study object the school curriculum, resulting from the implementation of public policies for inclusion in the Brazilian educational field and of the teaching organization in State School Despertar. While we acknowledge advances in government discussions and proposals related to school inclusion in our country, it is still important to develop studies and interventions in the context of basic education focused on the curriculum. With methodological basis in collaborative-critical action research and contribution by Barbier, the survey was conducted in 2013, in a state school in the Natal - Rio Grande do Norte - school system, and aimed to analyze the curriculum of the State School Despertar, in particular issues related to the inclusion of students with disabilities in common teaching classes expressed in the school and in collective situations of continuing education with teachers and interpreter of Brazilian Sign Language (Libras). The school was previously chosen because it had already been locus of research in a study conducted by a professor at the Federal University of Rio Grande do Norte promoting the knowledge of their formative needs. The study subjects were 26 teachers in the early years and the end of elementary school and a Libras interpreter. The instruments were direct observation, semi-structured interviews, document analysis and a proposal for continuing education called Collaborative Group on School Inclusion (GCEI), established with the participating subjects and the other research collaborators. The analyzed data showed eight dialogues built with the State School Despertar, being basic the contributions of Goffman (1988) on stigma and of Forquin (1993) on school culture. As a theoretical framework, there were important contributions on School Curriculum (SACRISTÁN, 2000; 2007; APPLE, 2006; 2008), School Inclusion (BUENO, 2008), Continuing Education (NÓVOA, 2002; GATTI, 2003) and the existing studies on the dialogues between Curriculum and Special Education (MAGALHÃES, 2002; SILVA, 2008; 2010; OLIVEIRA, 2004; VIEIRA, 2012). The study highlighted the importance of extending the dialogue, the theoretical deepening of GCEI for the understanding of school curriculum and the specifics of any students, with or without disability. It will be necessary to revisit the school teaching practices that do not correspond to the students, for instance the formation of classes made in classrooms. It is also important to consider the organization of the school day and its interface with the pedagogical functions of each member of the school in building curriculum practices consistent with the diversity of modes and learning styles. Subliminal aspects of the curriculum should be reviewed, given its implications in the context of the classroom and management. However, significant changes identified in the practices of some teachers, such as the use of audio description, stimulus to the participation of students with disabilities and use of images, favored the development of other students, who benefit of more exciting and participatory classes. Based on the conducted research, we conclude on the importance of collectively discuss the conditions for / in schooling of different students and the (re)thinking of curriculum practices in the school as a whole, and therein lies a paradox because, on the one hand, it is not about minimizing the specific knowledge in dealing with the needs of students with disabilities, on the other, we are not interested in distancing these needs from those inherent in human nature, therefore peculiar to the other students. The questioning of our own practices is the challenge imposed, not to special education, or its target audience, but this is undoubtedly task of education.

Redes Sociais da Família Multiproblemática ou Família Multidesafios

Esta investigação surge no âmbito do Mestrado de Psicologia Clínica – Família e Intervenção Sistémica, da Escola Superior de Altos Estudos, do Instituto Superior Miguel Torga. A dissertação de mestrado intitulada As Rede Sociais da Família Multiproblemática ou Família Multidesafios – Estudo Exploratório, trata-se de um estudo exploratório e versa sobre as principais características das redes sociais destas famílias, seus principais problemas e particularidades, contemplando uma leitura macrosistémica (Bronfenbrenner, 1986; Fuster & Ochoa, 2000; Navarro, 2004; Rojano, 2004; Rosello, 2004). Foram exploradas as características estruturais, as características funcionais e os atributos do vínculo das redes sociais (Guay, 1984; Guédon, 1984; Barrón, 1996; Sluzki, 1996, 2000, 2007; Guadalupe, 2003, 2009; Alarcão & Sousa, 2007) das famílias multiproblemáticas ou multidesafios, concluindo-se que estas possuem maioritariamente redes de tamanho reduzido, de densidade média (redes fragmentadas). Os quadrantes das relações familiares, das relações institucionais e das relações de amizade assumem um peso significativo. As redes sociais demonstram ser localizadas, nos quadrantes anteriormente mencionados e no quadrante das relações de trabalho ou estudo constatamos uma ausência de relações. Foram analisadas as características funcionais, como o apoio emocional, o apoio informativo, e o apoio material e instrumental, concluindo-se que o apoio é reconhecido de forma positiva, pelas famílias. Relativamente, aos atributos do vínculo, a totalidade da amostra percepciona trocas equitativas do apoio (reciprocidade) e ao nível da frequência de contactos, as famílias referem contactos frequentes. Ao tentarmos identificar os principais problemas das famílias (Costa, 1998; Sousa, Hespanha, Rodrigues & Grilo, 2007) concluímos que se encontram em diferentes áreas e são percepcionados de forma diferente por famílias e profissionais.

Auswirkungen von Traumata auf Entstehung und Verlauf von somatoformen Beschwerden sowie die Wirksamkeit von psychodynamischer Psychotherapie bei dieser Patientengruppe

Zusammenhänge zwischen Trauma und Somatisierung wurden empirisch vielfach belegt. Zur Erklärung des Zusammenhangs bestehen verschiedene Theorien, u.a. die der unterbrochenen Handlung (Fischer, 2000, 2007), der unterbrochenen Informationsverarbeitung (Bering, 2011), der Dissoziation (Nijenhuis, 2004) und der Alexithymie (Krystal, 1979). Unklar ist, welche Art der Therapie traumatisierten, somatisierenden Patienten hilft, da die Psychosomatik als Outcome in der Traumatherapieforschung bislang häufig vernachlässigt wurde. In der vorliegenden Promotion wurde der Zusammenhang von Trauma und somatoformen Beschwerden sowie die Wirksamkeit psychodynamischer Psychotherapie bei dieser Patientengruppe untersucht. Hierzu wurde eine klinische, naturalistische Längsschnittstudie mit Prätest-Posttest-Design an einer Stichprobe ambulanter Psychotherapiepatienten durchgeführt. Die Ergebnisse (N = 248) zeigen, dass zwei Drittel der Somatisierungsvarianz mittels Traumata (insbesondere vor dem 6. Lj.), posttraumatischer und dissoziativer Symptomatik aufgeklärt werden können. Physische und sexuelle Gewalt sind die Subformen, die die stärksten Zusammenhänge mit Somatisierung aufweisen. Der Zusammenhang zwischen traumatischen Ereignissen und Somatisierung wird insbesondere durch PTBS-Symptomatik moderiert und durch Dissoziation partiell mediiert. Die längsschnittlichen Ergebnisse (n = 83) zeigen, dass nach psychodynamischer Psychotherapie (durchschnittlich 79 Std.) moderate bis große Effekte bezüglich der Verbesserung des Funktionsniveaus, der Reduktion der posttraumatischen, alexithymen, allgemeinpsychopathologischen, somatoformen und dissoziativen Symptome vorliegen. Entgegen der Hypothese liegt keine signifikante Veränderung der Inanspruchnahme des Gesundheitssystems vor. Negative Prädiktoren des Therapieverlaufs im Hinblick auf die Somatisierung sind Traumata (insbesondere vor dem 6. Lj.) sowie tendenziell starke Dissoziation und Alexithymie zu Therapiebeginn. Die Therapiedosis erweist sich als positiver, jedoch nicht signifikanter Prädiktor des Therapieerfolgs. Die Ergebnisse zeigen, dass somatoforme Symptome als Folge von Traumatisierung eher die Regel als die Ausnahme darstellen und durch Traumatherapie beeinflusst werden können. Sie verweisen zudem auf die Relevanz der Psychosomatik als Outcome in der Traumatherapieforschung. Zu diskutierende Limitationen der Untersuchung sind die reduzierte interne Validität des Feldstudiendesigns, das Fehlen einer Kontrollgruppe, die Auswahl der Outcome-Variablen inklusive des weitgehenden Fehlens multimodaler Bewertungen.

Is phraseology the third articulation of language? Fresh insights into a theoretical conundrum

Is phraseology the third articulation of language? Fresh insights into a theoretical conundrum Jean-Pierre Colson University of Louvain (Louvain-la-Neuve, Belgium) Although the notion of phraseology is now used across a wide range of linguistic disciplines, its definition and the classification of phraseological units remain a subject of intense debate. It is generally agreed that phraseology implies polylexicality, but this term is problematic as well, because it brings us back to one of the most controversial topics in modern linguistics: the definition of a word. On the other hand, another widely accepted principle of language is the double articulation or duality of patterning (Martinet 1960): the first articulation consists of morphemes and the second of phonemes. The very definition of morphemes, however, also poses several problems, and the situation becomes even more confused if we wish to take phraseology into account. In this contribution, I will take the view that a corpus-based and computational approach to phraseology may shed some new light on this theoretical conundrum. A better understanding of the basic units of meaning is necessary for more efficient language learning and translation, especially in the case of machine translation. Previous research (Colson 2011, 2012, 2013, 2014), Corpas Pastor (2000, 2007, 2008, 2013, 2015), Corpas Pastor & Leiva Rojo (2011), Leiva Rojo (2013), has shown the paramount importance of phraseology for translation. A tentative step towards a coherent explanation of the role of phraseology in language has been proposed by Mejri (2006): it is postulated that a third articulation of language intervenes at the level of words, including simple morphemes, sequences of free and bound morphemes, but also phraseological units. I will present results from experiments with statistical associations of morphemes across several languages, and point out that (mainly) isolating languages such as Chinese are interesting for a better understanding of the interplay between morphemes and phraseological units. Named entities, in particular, are an extreme example of intertwining cultural, statistical and linguistic elements. Other examples show that the many borrowings and influences that characterize European languages tend to give a somewhat blurred vision of the interplay between morphology and phraseology. From a statistical point of view, the cpr-score (Colson 2016) provides a methodology for adapting the automatic extraction of phraseological units to the morphological structure of each language. The results obtained can therefore be used for testing hypotheses about the interaction between morphology, phraseology and culture. Experiments with the cpr-score on the extraction of Chinese phraseological units show that results depend on how the basic units of meaning are defined: a morpheme-based approach yields good results, which corroborates the claim by Beck and Mel'čuk (2011) that the association of morphemes into words may be similar to the association of words into phraseological units. A cross-linguistic experiment carried out for English, French, Spanish and Chinese also reveals that the results are quite compatible with Mejri’s hypothesis (2006) of a third articulation of language. Such findings, if confirmed, also corroborate the notion of statistical semantics in language. To illustrate this point, I will present the PhraseoRobot (Colson 2016), a computational tool for extracting phraseological associations around key words from the media, such as Brexit. The results confirm a previous study on the term globalization (Colson 2016): a significant part of sociolinguistic associations prevailing in the media is related to phraseology in the broad sense, and can therefore be partly extracted by means of statistical scores.

A participação infantil no cotidiano da escola: crianças com voz e vez

A presente dissertação centra-se no estudo da participação infantil no cotidiano escolar, mais precisamente, das instituições de Educação Infantil. Para tanto, assumo como fundamental perceber a criança enquanto ator social, produtor de cultura e a infância como uma categoria social, geracional. O objetivo principal deste estudo é compreender quais as formas de participação de um grupo de crianças que compõe a turma de nível II, com 5 e 6 anos de idade, da Escola Municipal de Educação Infantil Tia Luizinha, a partir de suas manifestações no cotidiano escolar, buscando perceber quais são os momentos da rotina que as crianças percebem que participam, o que elas pensam sobre esses momentos e como os significam. Para tanto, o referencial teórico-metodológico utilizado para dialogar com esta investigação é oriundo da perspectiva da Sociologia da Infância (SARMENTO, 1997; 2000; 2007, CORSARO 2011, DELGADO, 2004; 2007), que percebem as crianças como sujeitos de direitos, capazes de participar/opinar sobre o meio no qual estão inseridas. Trata-se de uma pesquisa sobre o contexto escolar, cuja metodologia busca inspirações etnográficas, ou seja, é o cotidiano com as crianças, narrado por quem tornou-se ator desta pesquisa, juntamente com elas. Neste sentido, cabe ressaltar que é um processo investigativo COM crianças e não sobre elas. Os principais instrumentos metodológicos utilizados foram a observação, a escuta, os registros, os desenhos das crianças e suas falas. No tratamento dos dados que foram sendo gerados no percorrer da pesquisa, percebi a emergência de duas categorias de análise: a participação das crianças na RODA DE CONVERSA e no PÁTIO da escola. Neste sentido, estabeleço relação entre a infância e os espaços por elas escolhidos como sendo de maior participação, vindo a encontrar eco nos estudos da Geografia da Infância (LOPES, 2008). Foi possível perceber o quanto as crianças atribuem sentidos muito particulares aos espaços nos quais se inserem. A roda de conversa, configurava-se como um espaço/tempo dialógico do cotidiano, porém, ainda muito vinculada com a presença marcante do adulto-orientador. No pátio da escola, em especial, na pracinha, a participação infantil esteve intimamente relacionada a autonomia das crianças e as possibilidades de escolha que ali se apresentavam. Considero que os resultados deste estudo possam contribuir com as propostas pedagógicas das escolas da infância, no sentido acolher as manifestações das crianças, para assim, torná-las cada vez mais coautoras das ações pedagógicas.

Identification of telomere dysfunction in Friedreich ataxia.

Background: Friedreich ataxia (FRDA) is a progressive inherited neurodegenerative disorder caused by mutation of the FXN gene, resulting in decreased frataxin expression, mitochondrial dysfunction and oxidative stress. A recent study has identified shorter telomeres in FRDA patient leukocytes as a possible disease biomarker. Results: Here we aimed to investigate both telomere structure and function in FRDA cells. Our results confirmed telomere shortening in FRDA patient leukocytes and identified similar telomere shortening in FRDA patient autopsy cerebellar tissues. However, FRDA fibroblasts showed significantly longer telomeres at early passage, occurring in the absence of telomerase activity, but with activation of an alternative lengthening of telomeres (ALT)-like mechanism. These cells also showed accelerated telomere shortening as population doubling increases. Furthermore, telomere dysfunction-induced foci (TIF) analysis revealed that FRDA fibroblasts have dysfunctional telomeres. Conclusions: Our finding of dysfunctional telomeres in FRDA cells provides further insight into FRDA molecular disease mechanisms, which may have implications for future FRDA therapy.

Új tendenciák településeink megújulásában

Az ország népességszámának csökkenése a településhálózat szélső pólusain jelentkezik legerőteljesebben. Egyértelmű növekedés a főváros agglomerációjában, egyes üdülőterületeken és Nyugat-Magyarországon mutatható ki. Az ország 3154 településéből mindössze 160 népességszáma növekedett mind a 2000-2007 közötti, mind a 2007-2010 és 2010-2014 közötti időszakok egészében. Míg 2007-2010 között 600 település növekedési üteme volt pozitív, addig 2010-2014 között 1171. Nagyvárosaink közül 2007 után csak Budapest és Nyíregyháza népességszáma növekedett mindkét jelzett periódusban. Ezeken kívül míg 2007 és 2010 között csak Miskolc népességszáma csökkent, addig 2010 után az összes többi nagyvárosunké is.
