Estructura formal, textual y oral del discurso público

Estructura formal, textual y oral del discurso públicoExisten tres competencias comunicativas muy valoradas en la sociedad de la información. Primero, la búsqueda, selección y gestión de grandes cantidades de información. Segundo, la redacción de textos claros, concisos y rigurosos. Y en tercer lugar, la exposición y defensa oral de esta información en un discurso público. Tradicionalmente, los estudios de periodismo han abordado estas competencias de forma independiente. Pero actualmente, instituciones y empresas de ámbitos diferentes demandan un perfil profesional capaz de aplicarlas ante cualquier tipo de información y con objetivos diversos. Se propone un modelo integral en tres niveles estructurales basado en teorías, conceptos y estudios específicos de periodismo, oratoria, retórica… o comunicación, en los últimos años. Este modelo puede contribuir a encauzar las investigaciones de académicos y representa una herramienta de entrenamiento para profesionales.

Newcomer Integration in Online Knowledge Communities: Exploring the Role of Dialogic Textual Complexity

Using online knowledge communities (OKCs) as informal learning environments poses the question how likely these will integrate newcomers as peripheral participants. Previous research has identified surface characteristics of the OKC dialog as integrativity predictors. Yet, little is known about the role of dialogic textual complexity. This contribution proposes a comprehensive approach based on previously validated textual complexity indexes and applies it to predict OKC integrativity. The dialog analysis of N = 14 blogger communities with a total of 1937 participants identified three main components of textual complexity: dialog participation, structure and cohesion. From these, dialog cohesion was higher in integrative OKCs, thus significantly predicting OKC integrativity. This result adds to previous OKC research by uncovering the depth of OKC discourse. For educational practice, the study suggests a way of empowering learners by automatically assessing the integrativity of OKCs in which they may attempt to participate and access community knowledge.

Predicting Student Performance and Differences in Learning Styles based on Textual Complexity Indices applied on Blog and Microblog Posts

Social media tools are increasingly popular in Computer Supported Collaborative Learning and the analysis of students' contributions on these tools is an emerging research direction. Previous studies have mainly focused on examining quantitative behavior indicators on social media tools. In contrast, the approach proposed in this paper relies on the actual content analysis of each student's contributions in a learning environment. More specifically, in this study, textual complexity analysis is applied to investigate how student's writing style on social media tools can be used to predict their academic performance and their learning style. Multiple textual complexity indices are used for analyzing the blog and microblog posts of 27 students engaged in a project-based learning activity. The preliminary results of this pilot study are encouraging, with several indexes predictive of student grades and/or learning styles.

Assisting digital forensic analysis via exploratory information visualisation

Background: Digital forensics is a rapidly expanding field, due to the continuing advances in computer technology and increases in data stage capabilities of devices. However, the tools supporting digital forensics investigations have not kept pace with this evolution, often leaving the investigator to analyse large volumes of textual data and rely heavily on their own intuition and experience. Aim: This research proposes that given the ability of information visualisation to provide an end user with an intuitive way to rapidly analyse large volumes of complex data, such approached could be applied to digital forensics datasets. Such methods will be investigated; supported by a review of literature regarding the use of such techniques in other fields. The hypothesis of this research body is that by utilising exploratory information visualisation techniques in the form of a tool to support digital forensic investigations, gains in investigative effectiveness can be realised. Method:To test the hypothesis, this research examines three different case studies which look at different forms of information visualisation and their implementation with a digital forensic dataset. Two of these case studies take the form of prototype tools developed by the researcher, and one case study utilises a tool created by a third party research group. A pilot study by the researcher is conducted on these cases, with the strengths and weaknesses of each being drawn into the next case study. The culmination of these case studies is a prototype tool which was developed to resemble a timeline visualisation of the user behaviour on a device. This tool was subjected to an experiment involving a class of university digital forensics students who were given a number of questions about a synthetic digital forensic dataset. Approximately half were given the prototype tool, named Insight, to use, and the others given a common open-source tool. The assessed metrics included: how long the participants took to complete all tasks, how accurate their answers to the tasks were, and how easy the participants found the tasks to complete. They were also asked for their feedback at multiple points throughout the task. Results:The results showed that there was a statistically significant increase in accuracy for one of the six tasks for the participants using the Insight prototype tool. Participants also found completing two of the six tasks significantly easier when using the prototype tool. There were no statistically significant different difference between the completion times of both participant groups. There were no statistically significant differences in the accuracy of participant answers for five of the six tasks. Conclusions: The results from this body of research show that there is evidence to suggest that there is the potential for gains in investigative effectiveness when information visualisation techniques are applied to a digital forensic dataset. Specifically, in some scenarios, the investigator can draw conclusions which are more accurate than those drawn when using primarily textual tools. There is also evidence so suggest that the investigators found these conclusions to be reached significantly more easily when using a tool with a visual format. None of the scenarios led to the investigators being at a significant disadvantage in terms of accuracy or usability when using the prototype visual tool over the textual tool. It is noted that this research did not show that the use of information visualisation techniques leads to any statistically significant difference in the time taken to complete a digital forensics investigation.

Produção textual de adolescentes acerca da saúde sexual e reprodutiva: subsídios para atuação de enfermagem

Trata-se de um estudo exploratório-descritivo, com abordagem qualitativa, que teve por objetivo analisar as mensagens, acerca da promoção da saúde sexual e reprodutiva, produzidas por adolescentes de escolas públicas e particulares da cidade do Rio Grande, num concurso de redação e música promovido pelo Grupo Gestor Municipal (GGM) do Projeto Saúde e Prevenção nas Escolas (SPE), nos anos de 2007 e 2008. Após autorização pelo GGM para realização deste estudo, foram disponibilizadas para reprodução, via xérox, as 29 redações e as três letras de músicas inscritas nos concursos. Para o tratamento dos dados utilizou-se a técnica de análise de conteúdo na modalidade temática. Participaram 35 adolescentes, sendo 25 moças e dez rapazes, com idades entre onze e dezessete anos. Quanto à escolaridade, dois frequentavam a quinta série; doze a sexta, doze a sétima e nove a oitava. Apreendeu-se que, em sua produção textual, os(as) adolescentes revelaram as vulnerabilidades e fortalezas referentes à saúde sexual e reprodutiva. Entre os inúmeros fatores que aumentam a vulnerabilidade individual, social e programática, discorreram sobre a carência de informações, a dificuldade para transformar o conhecimento em prática, a sensação de imunidade, a violência familiar, a conduta repressora de pais e mães, as mensagens de cunho sexual veiculadas pela mídia, a necessidade de serem aceitos(as) pelo grupo, preconceitos, e falta de ações governamentais direcionadas a adolescentes. No que se refere às fortalezas, sabem que a informação é uma importante aliada para a promoção da saúde sexual e reprodutiva citando, entre as fontes acessíveis, os serviços públicos de saúde, a família e a escola. Demonstraram conhecimento acerca da alarmante propagação da epidemia da AIDS entre jovens, conhecendo os sinais e sintomas das DSTs mais comuns e as formas de prevenção. As moças enfatizaram a necessidade de compartilhar a responsabilidade preventiva com os rapazes, bem como de amor próprio e respeito mútuo. O acesso aos serviços de saúde também foi apresentado como indispensável ao adolescer saudável. Os(as) jovens demonstraram conhecimento sobre drogas seus efeitos e consequências. Referem-se à adolescência como um período gostoso, repleto de dúvidas, mas também cheio de potencialidades. Assim, os mesmos componentes apresentados como desencadeadores de vulnerabilidade podem torná-los(as) fortes e capazes de superar os desafios comuns a essa etapa da vida. Para que tal superação ocorra, é necessário que tenham acesso à informação e a problematizem; que sejam capazes de incorporá-las ao cotidiano, adotando práticas protegidas e protetoras; que haja diálogo, despido de tabus, censuras e preconceitos no ambiente familiar; que as escolas adotem de forma transversalizada temáticas referentes à saúde sexual e reprodutiva; que os serviços de saúde tenham infraestrutura para assegurar os direitos contidos no Estatuto da Criança e do Adolescente; entre outras estratégias fortalecedoras.

Desencontros legais e morais na pesca artesanal: a Educação Ambiental política para a transformação socioambiental em Rio Grande/RS e São José do Norte/RS

A dissertação intitulada “Desencontros legais e morais na pesca artesanal: a Educação Ambiental política para a transformação socioambiental em Rio Grande/RS e São José do Norte/RS” busca analisar a compreensão das comunidades de pescadores artesanais do Rio Grande e de São José do Norte acerca de aspectos do desencontro entre as normas legais pesqueiras e as normas morais daqueles atores sociais, e os reflexos na conservação do meio ambiente e no exercício da cidadania ambiental, a fim de colaborar, por intermédio da Educação Ambiental, com o fortalecimento dos pescadores para a reversão do atual quadro de crise social e ambiental vivenciada na pesca artesanal da região, bem como para refletir sobre a ineficiência das regras legais aplicáveis no estuário da Lagoa dos Patos. Para tanto os objetivos foram estruturados de forma a investigar os aspectos do desencontro mencionado; analisar seus reflexos no declínio da conservação dos recursos renováveis e no exercício da cidadania pelos pescadores artesanais; e apresentar alternativas possíveis pela e para a Educação Ambiental, enquanto educação política, visando a proporcionar a transformação socioambiental dos pescadores para a garantia de sua participação cidadã nas esferas de decisão relativas à sua vida social e profissional. A pesquisa teve uma abordagem qualitativa, com enfoque teórico-metodológico nas representações coletivas dos pescadores. O trabalho foi composto de levantamento bibliográfico e documental, que serviu de apoio para a obtenção das representações mediante a realização de grupos focais junto a quatro comunidades de pescadores nas cidades pesquisadas. Esse corpus de pesquisa foi analisado com base na metodologia Análise Textual Discursiva. Os resultados obtidos indicaram que a crise instaurada na pesca ultrapassa a dicotomia existente entre as leis ambientais e as normas morais dos pescadores artesanais, emergindo o aspecto da necessidade financeira e de sobrevivência de pescadores e de suas famílias. Verificou-se, outrossim, que o desencontro pesquisado refletiu negativamente na conservação dos recursos naturais, na medida em que gerou a falta de efetividade de leis relacionadas àquela atividade profissional, repercutindo desfavoravelmente no exercício da cidadania ambiental pelos pescadores. Concluiu-se que a Educação Ambiental política possui um papel fundamental para o empoderamento dos pescadores artesanais em busca de sua participação ativa nos processos de gestão dos recursos pesqueiros estuarinos, numa verdadeira governança participativa, voltada à conservação ambiental e edificação do bem coletivo.

Análise de programas de educação ambiental no licenciamento ambiental de usinas hidrelétricas no Rio Grande do Sul : um estudo de caso

O trabalho intitulado - Análise de programas de Educação Ambiental no licenciamento ambiental de usinas hidrelétricas no Rio Grande do Sul: um estudo de caso - busca fazer uma análise compreensiva, reflexiva e problematizadora das ações de Educação Ambiental realizadas durante o processo de licenciamento ambiental, como medidas mitigadoras e/ou compensatórias de impactos ambientais causados pela instalação/operação de empreendimentos hidrelétricos. O objeto de análise foi o Programa de Educação Ambiental da UHE São José, instalada no rio Ijuí, interior do estado. Utilizou-se o movimento recursivo e reflexivo para elaboração da pesquisa, onde a primeira fase foi composta pelo levantamento bibliográfico que serviu de base para as discussões propostas, e a segunda fase foi composta pela investigação do referido programa, tendo como corpus da pesquisa documentos e entrevistas, e utilizando-se da Análise Textual Discursiva (ATD) como metodologia de análise. Os resultados obtidos fazem refletir sobre a ocupação dos espaços do licenciamento ambiental por uma Educação Ambiental que vá além do simples cumprimento das leis e normas, mas que seja de fato integradora e participativa, e envolva o compromisso dos empreendedores, das comunidades atingidas e dos órgãos fiscalizadores, contribuindo com a gestão ambiental e a sustentabilidade dos locais em transformação.

Causality in Europeanization Research: A Discursive Institutional Analytical Strategy

Discourse analysis as a methodology is perhaps not readily associated with substantive causality claims. At the same time the study of discourses is very much the study of conceptions of causal relations among a set, or sets, of agents. Within Europeanization research we have seen endeavours to develop discursive institutional analytical frameworks and something that comes close to the formulation of hypothesis on the effects of European Union (EU) policies and institutions on domestic change. Even if these efforts so far do not necessarily amount to substantive theories or claims of causality, it suggests that discourse analysis and the study of causality are by no means opposites. The study of Europeanization discourses may even be seen as an essential step in the move towards claims of causality in Europeanization research. This paper deals with the question of how we may move from the study of discursive causalities towards more substantive claims of causality between EU policy and institutional initiatives and domestic change.

Autoritarismes étatiques et régulation religieuse du politique en République démocratique du Congo : analyse discursive de la parole épiscopale catholique sur les élections (1990-2015)

Centrée essentiellement autour de la parole épiscopale congolaise, la présente recherche porte sur les articulations de la religion et du politique dans une perspective limitée au catholicisme en RDC. En prenant pour base empirique la ville de Kinshasa, elle thématise les effets des dynamiques religieuses sur les fermentations sociales et les changements politiques dans un contexte d’autoritarisme. Celui-ci est, dans ce travail, problématisé comme le fait conjoint de l’institution étatique et de l’organisation religieuse catholique. Le choix de cette approche relationnelle basée sur les interactions entre religion et politique, permet d’inscrire ce travail dans le champ d’études des sciences des religions. L’approche retenue s’appuie également sur les avancées de la sociologie politique et éclaire la régulation religieuse du politique, rarement étudiée par les sciences humaines. Cette recherche s’inscrit donc à l’intersection entre l’histoire, la sociologie, les sciences politiques, l’anthropologie, l’analyse du discours, la philosophie et la théologie. Sa thèse centrale est organisée autour d’une question principale : comment la religion participe-t-elle à la régulation du politique dans le contexte d’autoritarisme caractéristique de la RDC ? La réponse à cette question croise l’approche fonctionnelle de la religion et l’analyse des déclarations institutionnelles de l’épiscopat congolais. Elle esquisse les relations entre, d’une part, contextes et événements sociopolitiques et d’autre part, discours et pratiques religieuses. Elle construit la scène religieuse à partir de la trajectoire sociopolitique, économique et culturelle de la RDC entre 1990 et 2015, sous les Présidents J.-D. Mobutu, L.-D. Kabila et J. Kabila. Elle étudie l'offre normative de sens de leurs éminences J.-A. Malula, F. Etsou et L. Monsengwo. L’analyse de la rhétorique de l’épiscopat sur les élections vérifie la plausibilité sociale et l’efficience politique de la parole épiscopale congolaise. Elle se ressource dans la pragmatique de la communication telle que mise en œuvre dans l’analyse argumentative du discours de R. Amossy et dans celle du discours politique de P. Charaudeau. En mettant la focale sur l’objet linguistique « vérité des urnes », la recherche pose au niveau normatif, juridique et éthique, le problème de l’institutionnalisation d’un État de droit en RDC. Les élaborations sur ce dernier niveau s’articulent autour de l’inscription de l’éthique dans l’agir politique. L’examen des modes conventionnels d’action des chrétiens (élections de 2006 et 2011) et non conventionnels (marche des chrétiens de 1992 et 2012) conduit à éclairer les modes de reproduction ou de contestation de l’autoritarisme étatique par l’organisation religieuse. Il permet de promouvoir une démocratie des valeurs et d’action adossée à la parrhêsia. L’introduction de l’aléthique dans la vie publique donne à voir la parole épiscopale congolaise comme un discours ethopoïétique. C’est sur ce point précis que les élaborations de M. Foucault sur la parrhêsia aident à thématiser la capacité de la religion à informer et à influencer la démocratisation de la RDC. De là, la requête formulée pour un nouveau système d’action institutionnelle de l’organisation religieuse, susceptible de promouvoir le courage de la vérité en situation autoritaire. Cette innovation permet de tenir ensemble les valeurs démocratiques et les valeurs de l’Évangile, en les corrélant à la cohérence axiologique, à la probité morale et à l’intégrité existentielle des protagonistes de la démocratisation de la RDC.

WOMEN, CYCLING, AND THE PUBLIC SPHERE: HOW DISCURSIVE AND COMMUNITY PRACTICES AFFECT ENGAGEMENT

This thesis considers the impact that discursive and community practices have on women’s access to the public sphere by examining female cyclists and a cycling community in Miami, Florida via interviews and observation. In the interviews, female cyclists frequently reported fears for their safety, including concern over harassment, when riding in public space. I interviewed participants of the cycling community and observed Emerge Miami’s meetings and events, where publicly organized cycling excursions were a major component. Using the theoretical and methodological lenses of Feminist Critical Discourse Analysis and Communities of Practice, I examined the interviews to understand how participants discursively framed and contextualized gender-based harassment. I found two meta-discourse frames in operation: a normative frame (that essentially accepted the status quo) and a feminist frame (that challenged the “naturalness” of women’s harassment as just what one had to live with). The feminist frame offered a pathway for women to exert control over their experiences and alter the cultural understanding of harassment’s meaning and effect. The local community practices of Emerge Miami also challenged the normative frames that often silence women, employing explicitly invitational practices, which demonstrates how local discursive and social activity can impact and increase women’s involvement by creating a more accessible space for women to engage with their local cycling community.

The Discursive Construction of Japanese Identity and its Haunting Others

This dissertation examined the formation of Japanese identity politics after World War II. Since World War II, Japan has had to deal with a contradictory image of its national self. On the one hand, as a nation responsible for colonizing fellow Asian countries in the 1930s and 1940s, Japan has struggled with an image/identity as a regional aggressor. On the other hand, having faced the harsh realities of defeat after the war, Japan has seen itself depicted as a victim. By employing the technique of discourse analysis as a way to study identity formation through official foreign policy documents and news media narratives, this study reconceptualized Japanese foreign policy as a set of discursive practices that attempt to produce renewed images of Japan’s national self. The dissertation employed case studies to analyze two key sites of Japanese postwar identity formation: (1) the case of Okinawa, an island/territory integral to postwar relations between Japan and the United States and marked by a series of US military rapes of native Okinawan girls; and (2) the case of comfort women in Japan and East Asia, which has led to Japan being blamed for its wartime sexual enslavement of Asian women. These case studies found that it was through coping with the haunting ghost of its wartime past that Japan sought to produce “postwar Japan” as an identity distinct from “wartime imperial Japan” or from “defeated, emasculated Japan” and, thus, hoped to emerge as a “reborn” moral and pacifist nation. The research showed that Japan struggled to invent a new self in a way that mobilized gendered dichotomies and, furthermore, created “others” who were not just spatially located (the United States, Asian neighboring nations) but also temporally marked (“old Japan”). The dissertation concluded that Japanese foreign policy is an ongoing struggle to define the Japanese national self vis-à-vis both spatial and historical “others,” and that, consequently, postwar Japan has always been haunted by its past self, no matter how much Japan’s foreign policy discourses were trying to make this past self into a distant or forgotten other.

Provenance and technological analysis of selected cuneiform tablets from the late second millennium BC

The aim of the present study is to examine a group of clay tablets by thin-section petrography and thermogravimetric analysis in order to assess specific problems related to their provenance and manufacture technology. Two sets of documents dating to the fourteenth-thirteenth centuries BC will be considered separately throughout the thesis, with different research questions in mind for each case study. The petrographic data will be compared when possible with the chemical composition of the tablets, determined by pXRF and/or INAA in previous studies. On the whole, this dissertation is an attempt to combine textual, archaeological, petrographic, chemical and thermogravimetric information in order to get a better understanding of the materiality and the historical implications of the objects under examination; Resumo: O objetivo do presente estudo é examinar um grupo de tabuletas de argila por petrografia e análise termogravimétrica, a fim de avaliar problemas específicos relacionados com a sua proveniência e tecnologia de fabricação. Dois conjuntos de documentos que datam dos séculos XIV-XIII a.C. serão considerados separadamente ao longo da tese, com diferentes questões de pesquisa em mente para cada estudo de caso. Os dados petrográficos serão comparados quando possível com a composição química das tabuletas, determinada por pXRF e/ou INAA em estudos anteriores. No seu conjunto, esta dissertação é uma tentativa de combinar informação textual, arqueológica, petrográfica, química e termogravimétrica a fim de obter uma melhor compreensão da composição material e das implicações históricas dos objetos em análise.

Analysis Of The Dna Fourier Transform-infrared Microspectroscopic Signature Using An All-reflecting Objective.

The Fourier transform-infrared (FT-IR) signature of dry samples of DNA and DNA-polypeptide complexes, as studied by IR microspectroscopy using a diamond attenuated total reflection (ATR) objective, has revealed important discriminatory characteristics relative to the PO2(-) vibrational stretchings. However, DNA IR marks that provide information on the sample's richness in hydrogen bonds have not been resolved in the spectral profiles obtained with this objective. Here we investigated the performance of an all reflecting objective (ARO) for analysis of the FT-IR signal of hydrogen bonds in DNA samples differing in base richness types (salmon testis vs calf thymus). The results obtained using the ARO indicate prominent band peaks at the spectral region representative of the vibration of nitrogenous base hydrogen bonds and of NH and NH2 groups. The band areas at this spectral region differ in agreement with the DNA base richness type when using the ARO. A peak assigned to adenine was more evident in the AT-rich salmon DNA using either the ARO or the ATR objective. It is concluded that, for the discrimination of DNA IR hydrogen bond vibrations associated with varying base type proportions, the use of an ARO is recommended.
