Aplicación del dibujo arquitectónico en 3D para el análisis histórico de los sistemas constructivos industrializados

La condición tridimensional de la construcción edificatoria precisa del uso del dibujo en 3D como la mejor herramienta de proyecto y transmisión de conocimientos técnicos y formales. El objetivo de esta comunicación es mostrar la aplicación de la expresión gráfica en 3D en un análisis histórico sobre la evolución de la envolvente industrializada en arquitectura, identificando sus principales condicionantes técnicos y constructivos. El estudio compara la evolución del uso de sistemas constructivos industrializados mediante un análisis gráfico de las soluciones constructivas más destacables. La metodología empleada se basa en la identificación y estudio de determinados sistemas constructivos industrializados compuestos por materiales ligeros así como de obras de arquitectura representativas por su influencia en la evolución de la envolvente arquitectónica en la segunda mitad del siglo XX. La representación gráfica en 3D ayuda a comparar las obras analizadas desde aspectos tecnológicos y formales, constatándose la utilidad del dibujo asistido por ordenador en el análisis constructivo realizado. En conclusión, el uso del dibujo arquitectónico en 3D contribuye, por la mejor comprensión de las características espaciales de las soluciones constructivas, al análisis de las propiedades materiales y funcionales de los sistemas constructivos industrializados y su aplicación al diseño arquitectónico, ayudando a perfeccionar su conocimiento e incrementando la calidad constructiva y compromiso social de las propuestas arquitectónicas.

Introducción

Este dossier se inicia con una entrevista de Teresa Basile a Néstor Rodríguez en la cual se abordan diversos conflictos territoriales, lingüísticos y culturales suscitados en la frontera entre Haití y República Dominicana, tanto en la historia de ambos países como en el presente. El artículo de Juan Valdez analiza en el contexto de la frontera domínico-haitiana, las discusiones sobre el valor del español y el kreyòl que ofrecen la oportunidad para examinar en qué modo específico las representaciones lingüísticas intervienen en las luchas políticas donde se construyen las nuevas identidades. En acorde con metodologías y aproximaciones elaboradas por sociólogos del lenguaje y lingüistas-antropólogos, analizo un corpus de textos representativos del discurso metalingüístico y de las relaciones haitiano-dominicanas. Mi análisis de la dimensión lingüística de los conflictos políticos aspira a contribuir a la reflexión crítica en búsqueda de alternativas a las miradas conflictivas, y a motivar el diálogo intercultural y la convivencia de grupos diversos

The stimulus-response curve and motor unit variability in normal subjects and subjects with amyotrophic lateral sclerosis

The behavior and stability of motor units (MUs) in response to electrical stimulation of different intensities can be assessed with the stimulus-response curve, which is a graphical representation of the size of the compound muscle action potential (CMAP) in relation to stimulus intensity. To examine MU characteristics across the whole stimulus range, the variability of CMAP responses to electrical stimulation, and the differences that occur between normal and disease states, the curve was studied in 11 normal subjects and 16 subjects with amyotrophic lateral sclerosis (ALS). In normal subjects, the curve showed a gradual increase in CMAP size with increasing stimulus intensity, although one or two discrete steps were sometimes observed in the upper half of the curve, indicating the activation of large MUs at higher intensities. In ALS subjects, large discrete steps, due to loss of MUs and collateral sprouting, were frequently present. Variability of the CMAP responses was greater than baseline variability, indicating variability of MU responses, and at certain levels this variability was up to 100 mu Vms. The stimulus-response curve shows differences between normal and ALS subjects and provides information on MU activation and variability throughout the curve.

A study of cluster analysis techniques and their applications

This thesis seeks to describe the development of an inexpensive and efficient clustering technique for multivariate data analysis. The technique starts from a multivariate data matrix and ends with graphical representation of the data and pattern recognition discriminant function. The technique also results in distances frequency distribution that might be useful in detecting clustering in the data or for the estimation of parameters useful in the discrimination between the different populations in the data. The technique can also be used in feature selection. The technique is essentially for the discovery of data structure by revealing the component parts of the data. lhe thesis offers three distinct contributions for cluster analysis and pattern recognition techniques. The first contribution is the introduction of transformation function in the technique of nonlinear mapping. The second contribution is the us~ of distances frequency distribution instead of distances time-sequence in nonlinear mapping, The third contribution is the formulation of a new generalised and normalised error function together with its optimal step size formula for gradient method minimisation. The thesis consists of five chapters. The first chapter is the introduction. The second chapter describes multidimensional scaling as an origin of nonlinear mapping technique. The third chapter describes the first developing step in the technique of nonlinear mapping that is the introduction of "transformation function". The fourth chapter describes the second developing step of the nonlinear mapping technique. This is the use of distances frequency distribution instead of distances time-sequence. The chapter also includes the new generalised and normalised error function formulation. Finally, the fifth chapter, the conclusion, evaluates all developments and proposes a new program. for cluster analysis and pattern recognition by integrating all the new features.

The application of artificial neural networks to the interpretation and classification of freshwater benthic invertebrate communities

This thesis presents a thorough and principled investigation into the application of artificial neural networks to the biological monitoring of freshwater. It contains original ideas on the classification and interpretation of benthic macroinvertebrates, and aims to demonstrate their superiority over the biotic systems currently used in the UK to report river water quality. The conceptual basis of a new biological classification system is described, and a full review and analysis of a number of river data sets is presented. The biological classification is compared to the common biotic systems using data from the Upper Trent catchment. This data contained 292 expertly classified invertebrate samples identified to mixed taxonomic levels. The neural network experimental work concentrates on the classification of the invertebrate samples into biological class, where only a subset of the sample is used to form the classification. Other experimentation is conducted into the identification of novel input samples, the classification of samples from different biotopes and the use of prior information in the neural network models. The biological classification is shown to provide an intuitive interpretation of a graphical representation, generated without reference to the class labels, of the Upper Trent data. The selection of key indicator taxa is considered using three different approaches; one novel, one from information theory and one from classical statistical methods. Good indicators of quality class based on these analyses are found to be in good agreement with those chosen by a domain expert. The change in information associated with different levels of identification and enumeration of taxa is quantified. The feasibility of using neural network classifiers and predictors to develop numeric criteria for the biological assessment of sediment contamination in the Great Lakes is also investigated.

Écfrasis y Lecturas Icono-textuales en las "Leyendas" de Gustavo Adolfo Bécquer

The relationship between literature and the visual arts is ancient and it has been studied from different conceptual frames. Scholars agree that both have a descriptive function and therefore share the common goal of portraying a fictional or nonfictional reality. Based on this correspondence between two different modes of artistic expression, the Roman poet Horace coined the well-known simile ut pictura poesis --as is painting so is in poetry-- which in turn functions as the theoretical underpinning of ekphrasis, a rhetorical device through which one medium of art tries to describe the essence and form of another medium of art, with the purpose of enhancing the original work described. Spanish post-romantic poet and writer Gustavo Adolfo Bécquer (1836-1870) mastered this rhetorical strategy by expertly weaving all of his artistic interests into his prose. The purpose of this dissertation is to analyze how Bécquer makes his readers both see and hear through his prose. My semiotic research encompasses the various forms of ekphrasis used by Bécquer in the “Leyendas”. It shows how both images and symbols produce in readers sensory experiences that enhance their role as active participants in the creation of meaning. Thus, Bécquer´s prose is like a painting which not only tells a story, but also reflects reality through the eyes of the reader’s imagination. By using these ekphrastic strategies in his collection of short stories, Bécquer makes words, paintings, and music converge and collide with iconography, visual culture, and intertextuality. These components must be read, seen, heard, and understood to be more than just complementary to the text, but rather crucial elements, equal in importance to verbal expression. This analysis shows how Bécquer’s “Leyendas” not only tackle notions such as fantasy, figuration, and imagination, but also the importance of the reader´s gaze. Bécquer integrates processes such as imaginative action, iconization and visualization, into a semantic web whereby the reader creates his own particular hermeneutic image.

Representações discursivas de Lula nas capas das revistas Época e Veja

This doctoral dissertation proposes to analyze the discursive representations of Lula, as they appear on the covers of the magazines, Época and Veja, targeting the verbo visual elements that comprise the genre, magazine covers. In this way, we seek to describe and interpret the discursive representations (Drs), using a theoretical framework based on the Textual Discourse Analysis –TDA, developed by Jean Michel Adam (2011a), focusing on the semantic level of the text, that is, on the dimension that allows for the comprehension of Drs present in a text. For a discussion about the Drs and their categories of analysis referencing, predication, modification, relation and spatial localization and time we use as a starting point, the study by Brize about the logical discursive operations (1990, 1996), and continue through the studies that discuss linguistic, textual, and discursive operations in concrete utterances, such as Castilho (2010), Rodrigues; Passeggi; Silva Neto (2010), Neves (2011), Rodrigues et al. (2012), Passeggi (2001; 2012), Queiroz (2013), among others. In addition, we rely on Multimodal Discourse for the verbo visual aspects present on magazine covers (KRESS; van LEEUWEN, 2006; DIONISIO, 2011; DIONISIO; VASCONCELOS, 2013). Using aresearch approach that is qualitative with quantitative support, and which is documental, and based on deductive inductive methods, we describe and interpret a corpus (SEVERINO, 2007; CHIZZOTTI, 2010; OLIVEIRA, M., 2013), aiming to reconstruct Lula’s Drs. The cor pusis comprised of forty one magazine covers sixteen from Época and twenty four from Veja. The covers date from the election period in which the candidate, Lula, was elected President of Brazil in 2002, the last mandate after his reelection in 2006, and in the year 2010 a period of 9 years. Based on the analysis carried out, we can affirm that the magazines, Época and Veja, construct diverse Drs by Lula, such as: candidate; elected candidate; governing member and member of a political party; reelected president; politics; workers party acronym PT; international governments as allies; accomplices and participants in scandals of corruption; friend, brother, cousin, nephew, father, parent and man; among others that unfold throughout these by the mediation of the modifiers of the referents and processes, and by the very processes and connections, and analogies made on the object of discourse, Lula. Nonetheless, the reconstruction of these is derived from the description and interpretation of the textual linguistic and discursive choices that the magazines make to produce the proposition utterances, as well as by the choices of images and other visual resources, all operating as co(n)textually articulated to produce the magazine’s desired effect. In conclusion, the Drs verified demand the reflection, description and interpretation of the referencing, prediction, the relationship and spatial temporal localization, which was only possible through the textual discursive analysis of the verbo visual arrangements that comprise texts in the genre magazine cover.

O registro de procedimentos metodológicos em projetos de intervenção arquitetônica no patrimônio edificado: o caso de Natal-RN

In the midst of growing preservationist awareness, regarding methods of architectural intervention of buildings with a recognized heritage value, there are numerous approaches on how the original heritage value can be protected. However, can these intervention projects be differentiated? Is it possible to identify how they differ (if in fact they do) from an architectural project not related to preservation? Although there are numerous theoretical studies regarding methods utilized in architectonical projects, there appear to be a lack of studies focused on an architectural intervention exclusively focused on areas or edifications that have a recognized heritage value, thereby requiring a reflection on which methodological procedures in an architectonical project serve the purpose of the preservation of the historical aspects. This discussion is of even greater importance because, at the national level, some recent discussions on this type of architectural design seem arbitrary and lack methodological rigor. Therefore, this research attempts to focus equally on the theoretical-methodological practices of preservation as well as the architectural project methods. In an attempt to address these aspects, the focus of this research centers on the case studies of the intervention projects of the maritime passenger terminal of Natal (Terminal Marítimo de Passageriros de Natal), the old government hall (Palacio do Governo - EDTAM) and the old central hotel (Hotel Central) which are situated in the area known as the historic downtown of the city of Natal, within the federal heritage protection polygon. The analyses of these is intended to identify what methodological procedures were recorded in the final product (in the graphical representation of the architectural design and other documents) delivered to IPHAN / RN, the body responsible for review and approval of these architectural projects, noting whether such procedures appear, in some way, in the final product, and if an understanding of the complexity of preservation is evident. The analyses of these projects corroborate the hypothesis that there are unique characteristics, which must be addressed in the intervention project for preservation when compared to new project design. The main characteristic to be addressed is related to the very nature of the project. It is inherent in the dialectical relationship between the need to preserve (the identified heritage values) and the need to modernize (making adaptations to contemporary life). This relationship, denominated in this dissertation as "radical restraint", must, or at least should, guide the actions in the project as well as the technical analyses of the preservationist organization. However, this radical restriction appears more evident in the guidelines put forth by legislators than in the decisions of designers. These legislators require the presentation of documents, aimed at identifying and contextualizing intervention (Ordinance No. 420 of December 22, 2010), that grant (or should grant) assistance in the decision making process. It was evident in the analyses of these documents that there existed a disconnect between the documents produced and the decisions made in the project. This fact can be seen in the total absence of dialogue about theoretical-methodological preservationist principles, which, in our view, is an essential element of the methodological procedures of the intervention project needed to guide the legislative and project design discussions.

D6.3 – Semantic Content Annotation Support

The Semantic Annotation component is a software application that provides support for automated text classification, a process grounded in a cohesion-centered representation of discourse that facilitates topic extraction. The component enables the semantic meta-annotation of text resources, including automated classification, thus facilitating information retrieval within the RAGE ecosystem. It is available in the ReaderBench framework (http://readerbench.com/) which integrates advanced Natural Language Processing (NLP) techniques. The component makes use of Cohesion Network Analysis (CNA) in order to ensure an in-depth representation of discourse, useful for mining keywords and performing automated text categorization. Our component automatically classifies documents into the categories provided by the ACM Computing Classification System (http://dl.acm.org/ccs_flat.cfm), but also into the categories from a high level serious games categorization provisionally developed by RAGE. English and French languages are already covered by the provided web service, whereas the entire framework can be extended in order to support additional languages.

Exploring the joint compositional variability of major components and trace elements in the Tellus soil geochemistry survey (Northern Ireland)

The complexity of modern geochemical data sets is increasing in several aspects (number of available samples, number of elements measured, number of matrices analysed, geological-environmental variability covered, etc), hence it is becoming increasingly necessary to apply statistical methods to elucidate their structure. This paper presents an exploratory analysis of one such complex data set, the Tellus geochemical soil survey of Northern Ireland (NI). This exploratory analysis is based on one of the most fundamental exploratory tools, principal component analysis (PCA) and its graphical representation as a biplot, albeit in several variations: the set of elements included (only major oxides vs. all observed elements), the prior transformation applied to the data (none, a standardization or a logratio transformation) and the way the covariance matrix between components is estimated (classical estimation vs. robust estimation). Results show that a log-ratio PCA (robust or classical) of all available elements is the most powerful exploratory setting, providing the following insights: the first two processes controlling the whole geochemical variation in NI soils are peat coverage and a contrast between “mafic” and “felsic” background lithologies; peat covered areas are detected as outliers by a robust analysis, and can be then filtered out if required for further modelling; and peat coverage intensity can be quantified with the %Br in the subcomposition (Br, Rb, Ni).

Large-scale Roll Out of Online Prospective Measurement of Mood Symptoms in Affective Disorders

Background and Aims: True Colours is an online prospective mood-monitoring system developed at the University of Oxford to assist local patients and clinicians with monitoring course of illness in bipolar disorder. We report our initial experiences of using True Colours for research purposes in the Bipolar Disorder Research Network (BDRN; www.bdrn.org), a large research network of individuals with mood disorders spread throughout the UK. Methods: After initial piloting to ensure the practicality/acceptability of using True Colours within BDRN, we invited all BDRN participants (n = 7000) to participate in weekly True Colours ratings via three postal invitations sent over an 8-month period. Results: Following the three postal invitations, 915 individuals have so far expressed an interest in joining True Colours, and, of these, 662 (72.3%) have registered. 32 of those who registered for True Colours (5%) have so far asked to leave the system. Positive feedback from participants has focused around the ease of use and convenience of True Colours and potential clinical utility of the graphical representation of weekly mood scores. Conclusions: We have demonstrated that large-scale prospective mood monitoring for research purposes using a contemporary online approach is feasible. Challenges have included: (i) variation in participants’ technological ability; (ii) management of requests for clinical advice based on mood scores within a research setting; and, (iii) resources required to provide access and on-going support for participants using True Colours. We continue to expand recruitment to True Colours within BDRN, and plan to trial email invitations in the next phase of recruitment.

Facilitadores e barreiras para o desempenho de atividades por idosos que frequentam uma universidade aberta

Este estudo teve como objetivos: analisar fatores decorrentes da Classificação Internacional de Funcionalidade, Incapacidade e Saúde que atuam como facilitadores ou barreiras para o desempenho de atividades dos idosos que frequentam uma Universidade Aberta à Terceira Idade; propor ações de enfermagem/saúde para melhor aproveitamento do desempenho de atividades dos idosos que frequentam uma universidade aberta. Tratou-se de pesquisa qualitativa, do tipo exploratória e descritiva. Na coleta de dados, realizada em janeiro de 2014, utilizou-se a técnica Snowball (Bola de Neve) para inserir os dez participantes do estudo, aos quais foram aplicadas entrevistas semiestruturadas com a utilização de um formulário de pesquisa construído a partir dos domínios da Classificação Internacional de Funcionalidade, Incapacidade e Saúde: Atividades/Participação e Fatores Contextuais. Os dados foram analisados com base na Análise Textual Discursiva. Foram respeitados os aspectos éticos abordados na resolução 466/2012, obtendo-se o parecer de aprovação do Comitê de Ética em Pesquisa número 104/2013. Como categorias do estudo foram identificadas: Elementos facilitadores para o desempenho de atividades pelos idosos que frequentam uma Universidade Aberta à Terceira Idade; Elementos que servem como barreiras para o desempenho de atividades dos idosos que frequentam uma Universidade Aberta à Terceira Idade. Estas categorias possibilitaram a construção de propostas de enfermagem/saúde para melhor aproveitamento do desempenho de atividades de idosos que frequentam uma universidade aberta a terceira idade. Este estudo poderá propiciar um novo olhar ao desempenho das atividades e funcionalidade dos idosos, com a utilização de alguns elementos da Classificação Internacional de Funcionalidade, Incapacidade e Saúde, além de direcionar o cuidado de enfermagem a outro campo de atuação dos enfermeiros que diz respeito às Universidades Abertas à Terceira Idade.

A percepção dos trabalhadores da enfermagem acerca da avaliação de desempenho do servidor público

A concepção de avaliação de desempenho dos trabalhadores da enfermagem, na maioria das vezes, é a de um ato de julgamento entre o certo e o errado, relacionado às ações e posturas desenvolvidas no contexto do seu trabalho. A avaliação de desempenho, no entanto, pode ser visualizada pelos trabalhadores como um importante instrumento que favorece o feedback do fazer profissional, desafiando-os a olharem para si mesmos, para o desenvolvimento de suas atribuições profissionais, proporcionando um real entendimento de sua importância na sociedade. Assim tem-se como objetivo geral conhecer a percepção dos trabalhadores da enfermagem de um Hospital Universitário localizado no extremo sul do Rio Grande do Sul (HU) acerca da sistemática da avaliação dos servidores públicos vivenciada na instituição e como objetivo específico conhecer a percepção dos trabalhadores da enfermagem do HU acerca da sistemática da avaliação dos servidores públicos no período do estágio probatório, adotada na instituição. Trata-se de uma pesquisa com abordagem qualitativa do tipo exploratória, desenvolvida com 70 trabalhadores de enfermagem. Para a coleta de dados utilizou-se a técnica de entrevista. Mediante a análise textual discursiva, construíram-se duas categorias: A avaliação do desempenho na concepção de trabalhadores da enfermagem e Serviço público: representatividade para o serviço da enfermagem. A avaliação do desempenho do servidor público pode ser influenciada pelo período de estágio probatório, pela sua vulnerabilidade na instituição, com possibilidade de conquistar a estabilidade ou perdê-la. Decorrido o período probatório, alguns trabalhadores modificam seu comportamento, demonstrando, por vezes, falta de comprometimento com seu fazer. No entanto, tal mudança pode estar relacionada com a cultura organizacional existente na instituição pública e, ainda, com um aparente descontentamento dos trabalhadores na realização da avaliação de desempenho, por não receberem um retorno significativo de cada avaliação. Pensar a sistemática de avaliação de desempenho com os trabalhadores da enfermagem significou a possibilidade de desencadear um processo de discussão e de reflexão sobre os diferentes modos de ser e fazer a enfermagem.

Os sentidos do trabalho na tutoria a distância: buscando compreensões à luz da educação ambiental

A presente pesquisa está vinculada à linha Educação Ambiental: Ensino e Formação de Educadores(as) (EAEFE), do Programa de Pós-Graduação em Educação Ambiental - PPGEA/FURG. O estudo foi realizado com cinco tutoras a distância que atuaram no curso de Especialização em Educação de Jovens e Adultos na Diversidade, oferecido na modalidade a distância pela Universidade Federal do Rio Grande - FURG, a partir do Programa Universidade Aberta do Brasil, entre os anos de 2010 e 2012. A pesquisa buscou compreender que sentidos atribuem ao trabalho de tutoria, realizado no referido curso de especialização, os tutores a distância que dele fizeram parte. Assim, justifica-se por propor debate acerca da situação a que estão sujeitos esses profissionais, estando inseridos em um contexto de exploração, terceirização e prestação de serviços em educação, visto que a Educação a Distância, que não é institucionalizada, contribui para a manutenção do Sistema Capitalista, reproduzindo a precarização do trabalho docente. Este estudo caracteriza-se como uma pesquisa qualitativa, sendo os dados produzidos por meio de diálogo dirigido com questões que versavam a respeito das experiências das tutoras com a Tutoria a Distância. Para realizar a análise dos dados coletados, foi utilizada a Análise Textual Discursiva (ATD) (Moraes e Galiazzi, 2007), metodologia que possibilitou a compreensão dos discursos dos sujeitos. Os diálogos traçados entre os relatos das tutoras e teóricos como Antunes (2009), Mattar (2012), Loureiro (2004), entre outros, possibilitaram a construção de compreensões sobre o trabalho dos tutores no contexto do Modo de Produção Capitalista, vinculando, assim, a pesquisa ao campo de discussões da Educação Ambiental. Neste estudo, três categorias emergiram do processo de análise, denominadas: Tutoria a distância - questões que influenciam as condições de trabalho; Os sentidos do tempo na Tutoria a Distância - limites do tempo dentro e fora do trabalho; Tutoria a distância e o relacionamento com os estudantes - desafios do trabalho e da aprendizagem na EaD. Nesse sentido, foram tecidas reflexões sobre o trabalho na sociedade capitalista a partir da teoria marxista e suas relações com a organização da Educação a Distância, pensando na posição que ela assume no cenário educacional brasileiro e considerando as implicações do modo de produção capitalista na organização do trabalho da tutoria em EaD. Nas três categorias, os sujeitos elencaram desafios, dificuldades e as satisfações relacionadas com as experiências vivenciadas na tutoria a distância. Os resultados mostraram que os sujeitos da pesquisa consideram-se pertencentes ao processo de aprendizagem, desempenhando ações educativas que as caracterizam como professoras, pois como tutoras desempenham funções docentes no processo de formação dos educandos. Também fica evidente que as tutoras não identificam o trabalho na tutoria como um trabalho precarizado, embora essa atividade esteja constituída na lógica de exploração e terceirização da mão de obra trabalhadora. Além disso, houve a confirmação de que a realização das atividades de tutoria intensifica a jornada de trabalho e de que ele é organizado em cima do tempo livre das tutoras.
