Imagens para além do olhar : escritas possíveis na escola especialFerreira, Anelise Barra January 2004 (has links)
A presente dissertação visa, ao mapear e analisar as concepções elaboradas pelos alunos na aquisição do sistema de escrita no contexto da escola especial, oferecer uma versão das possibilidades de aprendizagem dos alunos “com deficiência mental”. As produções e interpretações escritas (escrita do nome, palavras, frases, textos) realizadas na dinâmica da sala de aula de uma turma coordenada pela pesquisadora apresentaram nove alunos na condição de “leitores e de escritores em processo”, construtores de variadas e particulares reflexões em interação com este objeto de conhecimento. A intervenção efetiva da professora e do contexto escolar enquanto intérpretes e informantes deste conhecimento culturalmente organizado tornou-se fundamental no sentido de oferecer uma série de vivências significativas com atos de leitura e escrita, possibilitando aos alunos um questionar-se e o desejo de apropriar-se da cultura escrita. Observou-se uma rede (não linear) de concepções que oscilavam entre diferentes níveis de conceitualização. O olhar teórico foi determinante no sentido de possibilitar visualizar o processo de alfabetização, dando a compreender o que poderia ser entendido como “erro, imaturidade ou deficiência” como formas de pensar diferenciadas da convencional, pertinentes ao processo de desenvolvimento e de aprendizagem em geral, como nos mostram os autores Emilia Ferreiro, Ana Teberosky e David Olson. Reconheceu-se o sujeito inventivo da teoria piagetiana. Este entendimento marca possibilidades de se viver novas formas de ser, diferenciadas do padrão “deficiente mental”: o de um aluno que também pode vir a ser letrado, independentemente de dominar ou não a forma oficial do sistema de escrita. Uma pessoa que assina seu nome e suas aprendizagens. / The present dissertation presents the concepts students with mental deficiencies are able to build when acquiring the written code, and discusses a version of these students´ learning possibilities. Their written productions and interpretations (spelling of names and words, writing of full statements and texts) emerge as a result of a classroom dynamic work coordenated by the present researcher. The study finds out nine students as readers-and-writers-in-process – able of producing varied and private reflections in interaction with the target object. The effective intervention of the teacher and the whole school context, as interpreters and communicators of this culturally-organized-knowledge, became crucial factors to offer students a series of meagninful experiences of life along to the reading and writing tasks, so the students behaved like questioning themselves and had the wish to acquire the written code. It was possible to observe a growing network of concepts (not in a linear basis), which floated among different levels of nominalization. The theoretical choice, making it clear what we should consider or should not consider as an “error”, “imaturity” or a “deficiency”. It also was decisive to best visualize the literacy process in a different approach from the ones used by convencional learning and development practices, as Emilia Ferreiro, Ana Teberosky and David Olson have pointed out. It made possible to recognize the inventive subject according to the piagetian theory. The understanding that underlines this work sets new possibilities of living new ways of being, which differ from the mental deficient standard. We talk about a student that is also able to become lectured, and that despite acquiring or not the official writen code, is a person who is able to sign his/her name and his/her productions.

Geologia e petrologia das rochas riolíticas do Cerro Ana Dias, Região de Quitéria, Sudeste do RSOliveira, Diego Skieresz de January 2015 (has links)
As manifestações vulcânicas e sub-vulcânicas riolíticas do Neoproterozoico do sul do Brasil são correlacionados a um intenso magmatismo ácido, ligados à diferentes associações petrotectônicas do Escudo Sul-Rio-Grandense. Uma porção deste vulcanismo ocorre no Cinturão Dom Feliciano, associado ao Batólito de Pelotas, e é resultante de episódios magmáticos vinculados à ambientes pós-colisionais relacionados com os estágios finais do Neoproterozoico no sul do Brasil. O Riolito Ana Dias é a principal ocorrência sub-vulcânica deste vulcanismo e está situado na região de Quitéria, na parte central do Rio Grande do Sul. O magmatismo ácido tem sido comumente associado com as fases mais diferenciadas das suítes graníticas durante os estágios finais de evolução do Batólito de Pelotas. O Riolito Ana Dias é caracterizado como um corpo intrusivo, constituído por rochas que apresentam textura porfirítica à seriada, variando para termos equigranulares finos. Novas idades U-Pb obtidas em zircões indicam uma idade de cristalização de 581,9 ± 1,9 Ma para estes riolitos. Dados geoquímicos caracterizam as rochas riolíticas como sendo da série alcalina. Apresentam um caráter metaluminoso a peraluminoso com teores elevados de SiO2, álcalis, FeOt/FeOt+MgO e índice agpaítico e baixos conteúdos de Al2O3, CaO e MgO. Os valores de Zr, Rb, Y, Nb e Ga são moderados em comparação com os conteúdos relativamente baixos de Ba e Sr. Estas características geoquímicas de elementos maiores e traços são comuns em magmas ácidos de afinidade alcalina, com caráter dominantemente metaluminoso. O padrão de alguns elementos-traços e ETR é caracterizado por um enriquecimento em elementos mais incompatíveis, o que juntamente com a anomalia negativa em Ba, o leve enriquecimento em Ce em relação aos elementos adjacentes e o enriquecimento de K2O e Rb em relação ao Nb, sugerem magmas derivados de fontes mantélicas, enriquecidas em elementos incompatíveis com alguma forma de participação crustal. As características químicas são semelhantes com as de magmatismo granítico do tipo A, relacionado a ambientes pós-colisionais. Os dados litoquímicos obtidos indicam uma vinculação genética com as rochas graníticas mais diferenciadas da Suíte Dom Feliciano do Batólito Pelotas, associadas ao magmatismo Neoproterozoico pós-colisional do Escudo Sul-Rio-Grandense. / Neoproterozoic volcanic and subvolcanic rhyolitic systems in southernmost Brazil are correlated with acid magmatism linked to different petrotectonic associations of the Sul-Rio-Grandense Shield. A portion of this volcanism in the Dom Feliciano Belt is associated with the Pelotas Batholith, which resulted from magmatic episodes associated with the Ediacaran post-collisional evolution of southern Brazil. Ana Dias Rhyolite is the main subvolcanic occurrence of this volcanism that took place in the Quitéria region, in the central part of Rio Grande do Sul State. The acid magmatism has been commonly associated with the most differentiated granite suite phases during the final stages of emplacement of the Pelotas Batholith. The Ana Dias Rhyolite is characterized as an intrusive body with rocks that present a porphyritic to seriated texture and a gradational variation to fine-grained equigranular rocks. New zircon U-Pb dating indicates crystallization age of 581.9 ± 1.9 Ma for the Ana Dias Rhyolite. Geochemistry data characterize the rhyolites as belonging to the alkaline series; they present a metaluminous to peraluminous character; elevated SiO2 and alkali concentrations, high FeOt/FeOt+MgO ratios and agpaitic index; and low Al2O3, CaO, and MgO contents. The Zr, Rb, Y, Nb, and Ga concentrations are moderate when compared with the relatively low Ba and Sr contents. These geochemistry characteristics are common in acid magmas with alkaline affinity. The behavior of certain trace elements and REE demonstrate enrichment in more incompatible elements, in addition to the negative anomaly of Ba, the slight enrichment in Ce relative to adjacent elements, as well as the enrichment in K2O and Rb relative to Nb, suggesting magmas derived from mantle sources enriched in incompatible elements with some crustal contamination. The chemical characteristics are similar to those of A-type granites associated with Neoproterozoic post-collision magmatism in the Sul-Rio-Grandense Shield.

Previous issue date: 2016-03-18 / Theatricality, Montage and Performance in the Art of Ana Maria Pacheco scrutinizes the visual
work of the plastic artist as a main visual body analysis on the series of ten paintings entitled In Illo
Tempore I-X (1994), elaborated in the 90 ́s. The approach of this work is that the art of Ana Maria
Pacheco (1943) is an intervallic montage of multiple temporalities, and under this perspective, we
are headed to assume that the artist reinterprets the cultural-historical universe of her environment
of origin and formation relating it dynamically and diversely in her visual work. It also investigates
the theatricality inherent in the artist ́s visual work, elaborated through the intervallic and
anachronistic montage of the culture, from which a potential performance on images derives to the
reception of viewers eyes. The methodology used in this work is a combination of bibliographical
research and image analysis starting from the process “constellation and work table” (Didi-
Huberman, 2013), which consists in entangling a collection of affinities and relationship between
the images themselves. The main concepts approached in this work are the notions of “montage”
(Didi-Huberman, 2013), “theatricality” (Féral, 2011), “geopoetics” (Lowenthal, 1982) and
“performance and reception” (Zumthor, 2007). / Teatralidade, Montagem e Performance na Arte de Ana Maria Pacheco investiga a obra visual da
artista plástica tendo como principal corpo visual de análise a série de dez pinturas intitulada In Illo
Tempore I-X (1994), elaborada na década de 90. A abordagem deste trabalho é a de que a arte de
Ana Maria Pacheco (1943) é uma montagem intervalar de múltiplas temporalidades e, sob essa
perspectiva, parte-se do princípio de que a artista reinterpreta o universo histórico-cultural de seu
ambiente de origem e formação e o relaciona de maneira dinâmica e diversa em sua obra visual.
Investiga-se a teatralidade presente na arte visual da artista, elaborada por meio da montagem
intervalar e anacrônica da cultura, da qual decorre uma potencial performance nas imagens para a
recepção do olhar do espectador. A metodologia utilizada neste trabalho é uma combinação de
pesquisa bibliográfica e análise de imagens a partir do processo de “constelação e mesa de
trabalho” (Didi-Huberman, 2013), que consiste em intrincar uma rede de afinidades e
relacionamentos das imagens entre si. Os conceitos principais abordados neste trabalho são as
noções de “montagem” (Didi-Huberman, 2013), “teatralidade” (Féral, 2011), “geopoética”
(Lowenthal, 1982) e “performance e recepção” (Zumthor, 2007).

Ana: ousadia que mudou o seu destino / Ana: daring that changed their destinyEunice Angelo de Morais 12 March 2007 (has links)
Análise dos dois primeiros capítulos que integram o livro de 1 Samuel da Bíblia Hebraica, com ênfase nos aspectos históricos, lingüísticos e literários. Neles encontra-se registrada a história de Ana, uma mulher que sofria muito por não ter filhos, uma vez que a outra esposa de seu marido os tinha. A esterilidade de Ana é revertida após ela orar a Deus, e prometer-lhe entregar o filho que viesse a ter ao serviço religioso. Uma comparação com outros personagens da Bíblia Hebraica é feita, para demonstrar quais atitudes de Ana fazem dela uma das personagens femininas mais notáveis do Antigo Israel. Ao final, verifica-se também como o poema inserido nessa narrativa influenciou a literatura cristã. / Analyses of two first chapters that integrate the 1 Samuel book of Hebrew Bible, with emphasis in historical, liguistics and literary aspects. In these chapters we find the history of Hannah, a woman that suffered very much because she hasn\'t childrens and because the other wife of her husband has got them. The Hannah\'s sterility changed after she prays to God, and promisses to give the son that wasborn to the religious service. A comparision with others Hebrew Bibles characters is done to demonstrate which actitudes of Hannah make of her one of the most notable females characters of Ancient Israel. At the end we notice too how the poetry inserted into this narrative has influenced the christian literature.

Solubility and Stability of Scorodite and Adsorbed and Coprecipitated Arsenical 6-line Ferrihydrite in the Presence of Shewanella putrefaciens CN32 and Shewanella sp. ANA-3Revesz, Erika January 2015 (has links)
Mining and mineral processing generate a wide range of As-rich minerals, including scorodite (FeAsO4•2H2O), and arsenical ferrihydrite, which are common secondary minerals found in mine tailings. Scorodite and arsenical ferrihydrite are relatively stable under a wide range of physico-chemical conditions which makes them suitable arsenic sinks in mining environments. However, bacteria can reduce these minerals and release arsenic into the aqueous environment. Two dissimilatory iron and arsenic reducing bacteria, Shewanella sp. ANA-3 and Shewanella putrefaciens CN32, were used to investigate their effects on the reductive dissolution of scorodite and arsenical 6-line ferrihydrite in a chemically defined medium containing low phosphate concentrations representative of the natural environment. Analysis of the aqueous phase of all biotic reduced samples found mainly As(III), the more toxic form of As, while very little As(V) was reduced in the abiotic samples. Solid state analysis of the scorodite biotic post-reduction minerals identified scorodite, biogenic Fe(II)-As(III) compounds, parasymplesite and tooeleite, while in the biotic reduced arsenical six-line ferrihydrite, biogenic Fe(II)-As(III) compounds, hematite, akaganeite and unconfirmed magnetite were identified as secondary reduction products. Results from this research add to the body of literature on As and Fe biogeochemistry and provide very useful information for future assessments of the long term stability of As-rich minerals.
L’activité minière et la transformation du minerai génèrent divers minéraux riches en arsenic, tels la scorodite (FeAsO4•2H2O) et la ferrihydrite riche en arsenic, lesquels sont des minéraux secondaires communs des résidus miniers. Comme la scorodite et la ferrihydrite riche en arsenic sont relativement stables sous une grande gamme de conditions physico-chimiques, ces minéraux peuvent potentiellement être utilisés pour stocker de façon permanente l’arsenic dans les environnements miniers. Cependant, certaines bactéries peuvent réduire ces minéraux, ce qui entraine la solubilisation de l’arsenic. Deux bactéries capables de réduire l’arsenic et le fer, soit Shewanella sp. ANA-3 et Shewanella putrefaciens CN32, ont été utilisées afin de déterminer leurs effets sur la réduction microbienne de la scorodite et de la ferrihydrite riche en As dans un milieu de culture contenant de faibles concentrations de phosphate. Les analyses de la phase aqueuse ont démontré que dans tous les systèmes biotiques, As(V) a été réduit en As(III), alors que dans les systèmes contrôles abiotiques, peu de As(V) a été réduit. L’analyse des minéraux secondaires présents à la fin réduction dans les systèmes biotiques contenant de la scorodite indique que la scorodite est encore présente, ainsi que des composés organiques riches en Fe(II) et As(III), de la parasymplésite et de la tooéleite, alors que dans les systèmes biotiques contenant de la ferrihydrite riche en As, des composés riches en Fe(II) et en As(III), de l’hématite, de l’akaganéite et de la magnétique ont été identifiés comme minéraux secondaires. Les résultats de cette étude enrichissent la littérature sur le cycle biogéochimique du Fe et de As et fournissent de l’information importante pour l’évaluation de la stabilité à long terme de minéraux riches en As.

Role of Tyrosine-Related Kinase B Inhibition in the Mesocorticolimbic Stress and Reward Circuitries of the Adolescent and Adult Brain Following a Heterotypic Stress RegimenAzogu, Idu January 2017 (has links)
The mesocorticolimbic system is involved in fundamental processes that drive motivational behaviors essential for survival (feeding, reproduction and sexual behavior, etc.), as well as neurochemical activity involved in mood regulation. Stressful life events are an important cause of dysregulated psychological functioning, which in some leads to a pathophysiology of mood disorders. A source of such disorder could be, among other underlying factors, an impairment of synaptic plasticity induced by alterations in the levels of neurotrophins and/or aberrant glucocorticoid responses. The role of the brain derived neurotrophic factor (BDNF) and its high affinity receptor tyrosine-related kinase B (TrkB) in the mesocorticolimbic reward circuitry has been largely studied in adulthood, yet a possible role of this system in mediating memory and emotional responses induced by stress during the juvenile, adolescence period has not been elucidated. The proposed set of thesis studies are designed to investigate the roles of BDNF and TrkB signaling, via the selective and non-competitive TrkB antagonist, ANA-12 (N-[2-[[(Hexahydro-2-oxo-1H-azepin-3-yl)amino]carbonyl]phenyl] benzo[b]thiophene-2-carboxamide), in the expression of stress-induced changes in the brain stress circuitry (including the medial prefrontal cortex (mPFC), hypothalamic-pituitary-adrenal (HPA) axis, and hippocampus) and reward signaling systems of the brain (including the nucleus accumbens (NAc) and ventral tegmental area (VTA)). In addition, experiments aim to determine behavioral changes following stress exposure in male and female Wistar rats. Finally, the possible interplay between BDNF, dopamine, glutamate and orexins in response to repeated stress is examined. Articles 1 and 2, aimed to assess the biochemical and behavioral effects of direct ANA-12 infusion (0.25 µg/ 0.5µl) into the nucleus accumbens shell during exposure to a 10-day heterotypic stress paradigm in male rats. Specifically, Article 1 demonstrated a key role for BDNF/TrkB signaling to regulate stress-induced effects. Notably, the impact of ANA-12 to attenuate anxiety-like behavior in repeatedly stressed rats while increasing anxiety behavior in non-stress rats suggest an interesting behavioral and neurochemical state-dependent process induced by TrkB receptor signaling. Article 2 supports the key role for BDNF secretion in basal and stress-induced behaviors in rats suggesting an influence of TrkB in sociability, motivation and passive avoidance. Furthermore, this role of TrkB extended to increased expression of orexin A in the Perifornical area (PfA) and a decrease in the ventral CA1 of the hippocampus, and in stress-induced elevations in orexinergic projections to the VTA, of which reductions were observed in non-stress groups treated with ANA-12. Article 3 demonstrated gender-specific behavioral and biochemical responses in different developmental periods and the impact of TrkB activation, dependent on stress exposure, to affect the regulation of TrkB receptor isoforms (full length and truncated TrkB, TrkB.FL and TrkB.T1, respectively) in adulthood. Results revealed increased CORT responses in adolescent females relative to males and attenuated CORT secretions in both genders by TrkB inhibition. Elevated activity levels in young adult
females and increased passive coping behavior in the forced swim in stress-naïve females were also noted, in addition to novel observations on brain region and sex differences in TrkB receptor isoforms. Taken together, thesis findings derived from applications of ANA-12, shall foster knowledge on the contribution of BDNF in regulation of mood upon stress exposure at times when the brain is undergoing important maturation and remodelling, as well as on the relationship of stress exposure during adolescence and lasting brain and behavioral disorders in adulthood.

Inifrån Islamiska Staten : En studie om upprätthållning av den sociala ordningen under krigKahlil, Noor January 2020 (has links)
Denna studie syftar till att undersöka hur den sociala ordningen upprätthölls under Islamiska Statens territorium. Detta görs med kvalitativ maximal varierande intervjuer av åtta individer med olika kön, religionstillhörighet, yrkeserfarenhet och civilstånd som befunnit sig inom Islamiska Statens territorium. Studien kommer att utgå från Ana Arjonas teori om två typer av social ordning under krigszoner. De två typerna är rebellokrati och aliokrati. Materialet som i första hand kommer att användas är respondenternas utsagor men också sekundärkällor såsom nyhetsartiklar och rapporter från internationella organisationer. Resultatet för studien visar på att Islamiska Staten har haft stark tillvaro på att styra civilbefolkningen. Respondenterna bekräftar att gruppens interaktion tyder mer på en rebellokrati än en aliokrati till början av deras styre, i betydelsen att gruppen har utgått från ett socialt kontrakt för upprätthållningen där båda parterna har hållit sig till.
