This doctoral thesis deals with the transmission and reception of the works of Cyprian of Carthage in the early Middle Ages. The process of research combined the study of the manuscript transmission of Cyprian’s works with the study of texts that were (in an immediate way or not) influenced by these writings. The connections between the transmission of Cyprian’s writings and the publishing activities of various groups, from the Donatists in fourth-century North Africa to Carolingian priests, is a central part of the thesis. The appropriation of the Church Father by different groups, including Arian writers in the aftermath the Council of Aquileia, proves not only the sense of authority Cyprian’s works invoked but also the, often liberal, way in which ancient works were used or interpreted. In addition, Cyprian was the first Latin Church Father to connect the concept of the unity of the Church with the office of the bishop. He was therefore influential in medieval ecclesiological thought and in the shaping of episcopal identities throughout the early Middle Ages. The thesis examined how Cyprian’s works functioned as tools of legitimisation for the causes of ninth-century bishops, such as Hincmar of Reims; invocations of priestly and episcopal identity, which were often based on Cyprian’s contribution to Catholic theology, enabled influential bishops to affirm their place in a Christian society as major players in ecclesiastical and secular politics.

Motivation Translational bioinformatics(TBI) has been defined as ‘the development and application of informatics methods that connect molecular entities to clinical entities’ [1], which has emerged as a systems theory approach to bridge the huge wealth of biomedical data into clinical actions using a combination of innovations and resources across the entire spectrum of biomedical informatics approaches [2]. The challenge for TBI is the availability of both comprehensive knowledge based on genes and the corresponding tools that allow their analysis and exploitation. Traditionally, biological researchers usually study one or only a few genes at a time, but in recent years high throughput technologies such as gene expression microarrays, protein mass-spectrometry and next-generation DNA and RNA sequencing have emerged that allow the simultaneous measurement of changes on a genome-wide scale. These technologies usually result in large lists of interesting genes, but meaningful biological interpretation remains a major challenge. Over the last decade, enrichment analysis has become standard practice in the analysis of such gene lists, enabling systematic assessment of the likelihood of differential representation of defined groups of genes compared to suitably annotated background knowledge. The success of such analyses are highly dependent on the availability and quality of the gene annotation data. For many years, genes were annotated by different experts using inconsistent, non-standard terminologies. Large amounts of variation and duplication in these unstructured annotation sets, made them unsuitable for principled quantitative analysis. More recently, a lot of effort has been put into the development and use of structured, domain specific vocabularies to annotate genes. The Gene Ontology is one of the most successful examples of this where genes are annotated with terms from three main clades; biological process, molecular function and cellular component. However, there are many other established and emerging ontologies to aid biological data interpretation, but are rarely used. For the same reason, many bioinformatic tools only support analysis analysis using the Gene Ontology. The lack of annotation coverage and the support for them in existing analytical tools to aid biological interpretation of data has become a major limitation to their utility and uptake. Thus, automatic approaches are needed to facilitate the transformation of unstructured data to unlock the potential of all ontologies, with corresponding bioinformatics tools to support their interpretation. Approaches In this thesis, firstly, similar to the approach in [3,4], I propose a series of computational approaches implemented in a new tool OntoSuite-Miner to address the ontology based gene association data integration challenge. This approach uses NLP based text mining methods for ontology based biomedical text mining. What differentiates my approach from other approaches is that I integrate two of the most wildly used NLP modules into the framework, not only increasing the confidence of the text mining results, but also providing an annotation score for each mapping, based on the number of pieces of evidence in the literature and the number of NLP modules that agreed with the mapping. Since heterogeneous data is important in understanding human disease, the approach was designed to be generic, thus the ontology based annotation generation can be applied to different sources and can be repeated with different ontologies. Secondly, in respect of the second challenge proposed by TBI, to increase the statistical power of the annotation enrichment analysis, I propose OntoSuite-Analytics, which integrates a collection of enrichment analysis methods into a unified open-source software package named topOnto, in the statistical programming language R. The package supports enrichment analysis across multiple ontologies with a set of implemented statistical/topological algorithms, allowing the comparison of enrichment results across multiple ontologies and between different algorithms. Results The methodologies described above were implemented and a Human Disease Ontology (HDO) based gene annotation database was generated by mining three publicly available database, OMIM, GeneRIF and Ensembl variation. With the availability of the HDO annotation and the corresponding ontology enrichment analysis tools in topOnto, I profiled 277 gene classes with human diseases and generated ‘disease environments’ for 1310 human diseases. The exploration of the disease profiles and disease environment provides an overview of known disease knowledge and provides new insights into disease mechanisms. The integration of multiple ontologies into a disease context demonstrates how ‘orthogonal’ ontologies can lead to biological insight that would have been missed by more traditional single ontology analysis.

Entre elas o Q'eqchi' como idioma e cultura maya, sobre o qual se desenvolve esta investigação, no campo das ciências da linguagem, adotando os aportes da linguística textual. Neste processo participaram mestres (professores) que trabalham em cinco escolas de Xch'ool Ixim, eles recolheram algumas narrações que se utilizam para a trasmissão de determinados ensinamentos e emoções, ao realizar a análise dos dados foi possível detectar alguns resultados relacionados com a narratividade Q'eqchi', este gênero textual apresenta uma configuração em seus aspectos situacionais, formais e semânticos. Apresenta algumas características das quais se destacam a ação dos personagens, a contextualização dos fatos e uma estrutura lógica. Cada narração tem um objetivo e um destinatário, principlamente tem um campo moral e metafórico prórpio. Cumprem um papel importante na vida do Q'eqchi', é uma das formas que tem para educar e organizar seu conhecimento. O funcionamiento de determinadas unidades linguísticas permite que a narração Q'eqchi' tenta congruência e coerência entre as unidades A análise das formas lingüísticas das narrações em Q'eqchi' realizou-se desde três aspectos; Operações de Conexão, b) Operações de Coesão, c) Operações de Psicionamento Enunciativo e de Vozes de Enunciativas. A análise textual realizada na narração em idioma Q'eqchi', ofereceu resultados que podem traduzir-se em ferramentas lingüísticas e didáticas para os processos ensino - aprendizagem

O objetivo desta tese é construir, através de trabalhos realizados na área de poéticas visuais, uma reflexão que procure compreender como a mulher negra é vista na sociedade brasileira atual e o modo pelo qual as sombras lançadas pela escravidão sobre esta população se refletem nas negrodescendentes ainda hoje, criando e perpetuando locais simbólicos e sociais para este grupo. Este questionamento será realizado tendo como base uma investigação que transita entre diferentes manifestações artísticas, que vão da instalação à gravura, sempre procurando os meios plásticos adequados para a produção das obras que irão tratar do problema. Uma breve análise sobre os motivos que levam à opção por determinados procedimentos técnicos necessários à realização dos trabalhos, a escolha e aplicação de diferentes meios artísticos e suas adaptações ao pensamento visual também fazem parte desta investigação. É ainda intenção do trabalho pensar sobre a forma de apresentação do texto que acompanha as obras produzidas e esclarecer os motivos da eleição por uma escrita de artista para o relato apresentado em conjunto com as imagens executadas. / The goal of this thesis is to offer, through artworks in the field of visual art, a reflection that seeks to comprehend how black women are seen in current Brazilian society and the way that shadows cast by slavery over this population is still reflected in female black descendants today, creating and perpetuating social and symbolic places for that group. This issue will be tackled on the basis of a research that moves across different art forms, ranging from installations to printmaking, and always looks for suitable art materials to produce the works that will address the problem. A brief analysis of the reasons for choosing certain technical procedures necessary to create the artworks, the choice and application of different artistic media, and the adaptation of them to the visual thinking are also part of this investigation. The work is also intended to think about the text format accompanying the artworks and give grounds for plumping for an \"artist writing\" to deliver the reports associated with the images.

A reconstrução por inferenciação permite estabelecer o elo entre as informações explícitas e as implícitas no co-texto, em um determinado contexto. A inferência é uma estratégia muito importante para que se tome um texto como coeso e coerente, em termos de progressão referencial, colaborando de maneira decisiva para a produção de sentidos.A partir dos pressupostos da Lingüística textual e das teorias sobre leitura, apresenta a relação autor-texto-leitor no processo de produção e recepção do texto. Analisaram-se quantitativa e qualitativamente produções de textos de alunos de Ensino Médio nas quais se verificou o uso de seqüências pronominais, de repetições lexicais, das expressões nominais definidas, anáforas indiretas no texto ou referentes ao contexto, as quais permitem ao leitor fazer inferências e aturar como co-autor na produção dos sentidos. / Abstract: The work investigates the mechanisms of reference used in High School student’s productions in order to leave hints so that the reader com make inferences during the reading to produce meanings of what is being read. The reconstructions through inference permits to stablish the link among the explicit and implicit pieces of information in the co-text, in a determined context. The inference is a very important strategy to make a text cohesive and coherent, in terms of reference progression, contributing in a essencial way in the meaning production. From the textual linguistic and the theories about reading. The work presents the relationship author-text-reader in the process of text production and reception. It was analysed High School student’s productions in quality and amount in which it was verified the use of pronominal sequences, of lexical repetitions, of defined nominal expressions, indirect anaphora in the text or referred to the context, wich allow the reader to make inferences and act as co-author in the production of meanings. / Doutor
