Criação de um Microtesauro na área da Dança

Este trabalho de Investigação teve como objetivo a construção de um microtesauro na área da Dança. Face à inexistência de um Tesauro especializado na área da Dança, quer a nível nacional, quer internacional, e para dar resposta às necessidades de uma recuperação mais eficaz de informação nas Unidades Documentaisi Especializadas em Dança. Neste caso, em particular, no Centro de Informação e Documentação (CDI) da Escola Superior de Dança (ESD). Percebeu-se que a construção deste microtesauro, tendo em conta as normas nacionais e internacionais para o efeito. No âmbito das funções desempenhadas no CDI foi identificada a necessidade de existir um instrumento de Linguagem Documental adequado, que permitisse nas Pesquisas bibliográficas, recuperar por Assunto os documentos existentes na Base de Dados. A Pesquisa Bibliográfica, apenas disponível por Título e por Autor, veio a revelar-se insuficiente, e a impossibilidade de pesquiasr os documentos por Assunto traduzia-se numa carência crescente dos utilizadores e do próprio Serviço. A Metodologia seguida para a construção deste Microtesauro, teve como base uma lista de Termos de Indexação construída a partir da análise de uma amostra de 125 monografias e a consulta de várias fontes de informção (monografias e obras de referência, linguagens documentais, e entrevistas informais a docentes da ESD). A análise, quantificação e qualificação dos termos que constituem este microtesauro teve o acompanhamento, avaliação e adequação contínua por parte de alguns docentes da ESD, investigadores e especialistas em Dança. A Dança, enquanto objeto de exploração teórica, revela-se uma disciplina transversal a várias áreas do conhecimento que, agrupadas em classes, correspondem a 8 áreas do saber, relacionadas com a Dança, tendo em consideração as temáticas do espólio documental do CDI e as matérias lecionadas nas Unidades Curriculares dos cursos de Licenciatura e Mestrados da ESD. O microtesauro na área da Dança, que resulta do nosso trabalho de investigação, é constituído por Descritores, Não-Descritores, e suas relações de equivalência hierárquicas e associativas, apresentando-se no final deste trabalho, em apêndice, devido à sua dimensão. O mesmo resulta de um processos de construção individual, inicialmente elaborado de forma manual e posteriormente transposto para um Software Documental CDS/ISIS para Windows, que veio agilizar a estruturação do microtesauro. Este microtesauro na área da Dança, em Língua Portuguesa, constitui um importante contributo para as Bibliotecas e Centros de Documentação que detêm documentação nesta área específica, dado colmatar uma lacuna existente neste domínio do conhecimento.

A Gestão Documental na Autoridade Portuária de Barcelona

Este relatório de estágio representa o trabalho desenvolvido na Autoritat Portuària de Barcelona (APB), mais precisamente no Centro de Documentação da Autoridade Portuária de Barcelona, num período de 150 horas, onde tive a oportunidade de passar pelos diferentes serviços de documentação e realizar as tarefas inerentes a uma Instituição com idêntica tipologia àquela onde presto idêntica atividade em Portugal. Descreve-se a empresa e o trabalho desenvolvido no Centro de Documentação (CENDOC), considerando todas as funções desenvolvidas ao nível da gestão documental, na biblioteca, no arquivo intermédio, histórico e no arquivo fotográfico. O serviço de Arquivo agiliza a gestão de um fundo documental com mais de 3.900 metros lineares de documentos textuais, 500 metros lineares de documentação gráfica e cartográfica e 75.000 fotografias. Também gere o Património Cultural Móvel da APB, tanto o fundo documental do Arquivo Histórico (textual e imagens), como as coleções de objetos artísticos de interesse histórico e cultural (pinturas, esculturas, artes decorativas, cartas náuticas, modelos de navios). Toda a documentação do Arquivo Intermédio foi devidamente tratada, higienizada e organizada num novo espaço de arquivo, com melhores condições de acondicionamento. Aproveitando este trabalho, foi desenvolvido um novo Plano de Classificação em maio de 2012, no mesmo período que desenvolvi o estágio, a fim de melhorar o serviço de Arquivo. O serviço da Biblioteca tem ao alcance dos seus utilizadores um fundo de 1276 publicações periódicas e mais de 2.300 monografias, catalogadas no programa informático CDS/ISIS. A sua classificação é feita com base na Classificação Decimal Universal (CDU), e a partir de um tesauro especifico elaborado pelos técnicos do CENDOC. Enquanto Técnica Superior no Centro de Documentação e Informação na Administração do Porto de Lisboa (APL), o desenvolvimento deste estágio trouxe um importante contributo para o serviço que desempenho no Centro de Documentação e Informação na Administração do Porto de Lisboa. Este Estágio possibilitou, sem dúvida, um melhor conhecimento teórico e prático no âmbito das tarefas inerentes ao mesmo, e a capacitação para o desenvolvimento de projetos relacionados com as funções que desempenho, no Centro de Documentação e Informação da Administração do Porto de Lisboa.

"Ella", de Juan Carlos Onetti. Necrofilia y ficción (Homenaje)

La autora reflexiona sobre el relato “Ella”, del uruguayo Juan Carlos Onetti, y sobre otras representaciones de la muerte de Eva Perón, escritas por Jorge Luis Borges, David Viñas y Néstor Perlongher. Afirma que en la Argentina de Perón ya confluían realidad y ficción, y que las múltiples biografías de Eva serían “un duelo de versiones narrativas entre la ficción y la historia o, si se prefiere, una metáfora de la historia”. Rosano plantea que, en los textos revisados, es la realidad la que adopta contornos fantasmagóricos, disparados por motivos diversos: la descomposición y el tópico del mal olor, la impostura del cuerpo embalsamado y del mandatario, el entrelazamiento entre lo político y lo sexual en la escena del velorio, la imagen de Eva, “una diosa que muestra sus encajes de novia de suburbio” pero también una siniestra y doliente “zombi escarlata”. Señala, finalmente, que los textos muestran a los fieles, esos “miles de necrófilos murmurantes y enlutados”, sometidos a la potencia del mito.

A review of currently available in-stream water-quality models and their applicability for simulating dissolved oxygen in lowland rivers

In this paper, a review is undertaken of the major models currently in use for describing water quality in freshwater river systems. The number of existing models is large because the various studies of water quality in rivers around the world have often resulted in the construction of new 'bespoke' models designed for the particular situation of that study. However, it is worth considering models that are already available, since an existing model, suitable for the purposes of the study, will save a great deal of work and may already have been established within regulatory and legal frameworks. The models chosen here are SIMCAT, TOMCAT, QUAL2E, QUASAR, MIKE-11 and ISIS, and the potential for each model is examined in relation to the issue of simulating dissolved oxygen (DO) in lowland rivers. These models have been developed for particular purposes and this review shows that no one model can provide all of the functionality required. Furthermore, all of the models contain assumptions and limitations that need to be understood if meaningful interpretations of the model simulations are to. be made. The work is concluded with the view that it is unfair to set one model against another in terms of broad applicability, but that a model of intermediate complexity, such as QUASAR, is generally well suited to simulate DO in river systems.

LDA or GGA? A combined experimental inelastic neutron scattering and ab initio lattice dynamics study of alkali metal hydrides

In a previous work, we carried out inelastic neutron scattering (INS) spectroscopy experiments and preliminary first principles calculations on alkali metal hydrides. The complete series of alkali metal hydrides, LiH, NaH, KH, RbH and CsH was measured in the high-resolution TOSCA INS spectrometer at ISIS. Here, we present the results of ab initio electronic structure calculations of the properties of the alkali metal hydrides using both the local density approximation (LDA) and the generalized gradient approximation (GGA), using the Perdew–Burke–Ernzerhof (PBE) parameterization. Properties calculated were lattice parameters, bulk moduli, dielectric constants, effective charges, electronic densities and inelastic neutron scattering (INS) spectra. We took advantage of the currently available computer power to use full lattice dynamics theory to calculate thermodynamic properties for these materials. For the alkali metal hydrides (LiH, NaH, KH, RbH and CsH) using lattice dynamics, we found that the INS spectra calculated using LDA agreed better with the experimental data than the spectra calculated using GGA. Both zero-point effects and thermal contributions to free energies had an important effect on INS and several thermodynamic properties.

Tyche

The word tyche (plural tychai) denotes an ancient Greek concept encompassing many aspects of fortune – chance, fate, luck, occurrence, even achievement, success, and wealth – both good and bad. As a personification of that concept, the goddess Tyche came to symbolize the fate and fortune of rulers and through them their cities; she thus emerged as the preeminent city goddess throughout the Hellenistic and Roman worlds. Her name is etymologically related to the verb tynchanein (“to hit, meet with, be favored with, happen accidentally”). The connection between the noun and verb is so close that it is difficult to distinguish in Greek literature between the deity and the abstraction.

Modelling the structure of a polymer glass poly(methylmethacrylate) through neutron scattering experiments

Determination of the local structure of a polymer glass by scattering methods is complex due to the number of spatial and orientational correlations, both from within the polymer chain (intrachain) and between neighbouring chains (interchain), from which the scattering arises. Recently considerable advances have been made in the structural analysis of relatively simple polymers such as poly(ethylene) through the use of broad Q neutron scattering data tightly coupled to atomistic modelling procedures. This paper presents the results of an investigation into the use of these procedures for the analysis of the local structure of a-PMMA which is chemically more complex with a much greater number of intrachain structural parameters. We have utilised high quality neutron scattering data obtained using SANDALS at ISIS coupled with computer models representing both the single chain and bulk polymer system. Several different modelling approaches have been explored which encompass such techniques as Reverse Monte Carlo refinement and energy minimisation and their relative merits and successes are discussed. These different approaches highlight structural parameters which any realistic model of glassy atactic PMMA must replicate.

SANS/WANS time-resolving neutron scattering studies of polymer phase transitions using NIMROD

We use new neutron scattering instrumentation to follow in a single quantitative time-resolving experiment, the three key scales of structural development which accompany the crystallisation of synthetic polymers. These length scales span 3 orders of magnitude of the scattering vector. The study of polymer crystallisation dates back to the pioneering experiments of Keller and others who discovered the chain-folded nature of the thin lamellae crystals which are normally found in synthetic polymers. The inherent connectivity of polymers makes their crystallisation a multiscale transformation. Much understanding has developed over the intervening fifty years but the process has remained something of a mystery. There are three key length scales. The chain folded lamellar thickness is ~ 10nm, the crystal unit cell is ~ 1nm and the detail of the chain conformation is ~ 0.1nm. In previous work these length scales have been addressed using different instrumention or were coupled using compromised geometries. More recently researchers have attempted to exploit coupled time-resolved small-angle and wide-angle x-ray experiments. These turned out to be challenging experiments much related to the challenge of placing the scattering intensity on an absolute scale. However, they did stimulate the possibility of new phenomena in the very early stages of crystallisation. Although there is now considerable doubt on such experiments, they drew attention to the basic question as to the process of crystallisation in long chain molecules. We have used NIMROD on the second target station at ISIS to follow all three length scales in a time-resolving manner for poly(e-caprolactone). The technique can provide a single set of data from 0.01 to 100Å-1 on the same vertical scale. We present the results using a multiple scale model of the crystallisation process in polymers to analyse the results.

Electronegative Low-Density Lipoprotein is Associated with Dense Low-Density Lipoprotein in Subjects with Different Levels of Cardiovascular Risk

Dyslipidemias and physicochemical changes in low-density lipoprotein (LDL) are very important factors for the development of coronary artery disease (CAD). However, pathophysiological properties of electronegative low-density lipoprotein [LDL(-)] remain a controversial issue. Our objective was to investigate LDL(-) content in LDL and its subfractions (phenotypes A and B) of subjects with different cardiovascular risk. Seventy-three subjects were randomized into three groups: normolipidemic (N; n = 30) and hypercholesterolemic (HC; n = 33) subjects and patients with CAD (n = 10). After fasting, blood samples were collected and total, dense and light LDL were isolated. LDL(-) content in total LDL and its subfractions was determined by ELISA. LDL(-) content in total LDL was lower in the N group as compared to the HC (P < 0.001) and CAD (P = 0.006) groups. In the total sample and in those of the N, HC, and CAD groups, LDL(-) content in dense LDL was higher than in light LDL (P = 0.001, 0.001, 0.001, and 0.033, respectively) The impact of LDL(-) on cardiovascular risk was reinforced when LDL(-) content in LDL showed itself to have a positive association with total cholesterol (beta = 0.003; P < 0.001), LDL-C (beta = 0.003; p < 0.001), and non-HDL-C (beta = 0.003; P < 0.001) and a negative association with HDL-C (beta = -0.32; P = 0.04). Therefore, LDL(-) is an important biomarker that showed association with the lipid profile and the level of cardiovascular risk.

Immunomodulatory effects of Pteridium aquilinum on natural killer cell activity and select aspects of the cellular immune response of mice

Pteridium aquilinum (bracken fern) is one of the most common plants. Epidemiological studies have revealed a higher risk of certain types of cancers (i.e., esophageal, gastric) in people who consume bracken fern directly ( as crosiers or rhizomes) or indirectly through the consumption of milk from livestock that fed on the plant. In animals, evidence exists regarding the associations between chronic bracken fern intoxication, papilloma virus infection, and the development of carcinomas. While it is possible that some carcinogens in bracken fern could be responsible for these cancers in both humans and animals, it is equally plausible that the observed increases in cancers could be related to induction of an overall immunosuppression by the plant/its various constituents. Under the latter scenario, normal tumor surveillance responses against nascent (non-bracken-induced) cancers or responses against viral infections ( specifically those linked to induction of cancers) might be adversely impacted by continuous dietary exposure to this plant. Therefore, the overall objective of this study was to evaluate the immunomodulatory effects of bracken fern following daily ingestion of its extract by a murine host over a period of 14 ( or up to 30) days. In C57BL/6 mice administered ( by gavage) the extract, histological analyses revealed a significant reduction in splenic white pulp area. Among a variety of immune response parameters/functions assessed in these hosts and isolated cells, both delayed-type hypersensitivity (DTH) analysis and evaluation of IFN gamma. production by NK cells during T(H)1 priming were also reduced. Lastly, the innate response in these hosts-assessed by analysis of NK cell cytotoxic functionality-was also diminished. The results here clearly showed the immunosuppressive effects of P. aquilinum and that many of the functions that were modulated could contribute to the increased risk of cancer formation in exposed hosts.

Basic aminopeptidase activity is an emerging biomarker in collagen-induced rheumatoid arthritis

The objective of this study was to investigate the catalytic activity of basic aminopeptidase (APB) and its association with periarticular edema and circulating tumor necrosis factor (TNF)-alpha and type II collagen (CII) antibodies (AACII) in a rat model of rheumatoid arthritis (RA) induced by CII (CIA). Edema does not occur in part of CH-treated, even when AACII is higher than in control. TNF-alpha is detectable only in edematous CII-treated. APB in synovial membrane is predominantly a membrane-bound activity also present in soluble form and with higher activity in edematous than in non-edematous CH-treated or control. Synovial fluid and blood plasma have lower APB in non-edematous than in edematous CII-treated or control. In peripheral blood mononuclear cells (PBMCs) the highest levels of APB are found in soluble form in control and in membrane-bound form in non-edematous CII-treated. CII treatment distinguishes two categories of rats: one with arthritic edema, high AACII, detectable TNF-alpha, high soluble and membrane-bound APB in synovial membrane and low APB in the soluble fraction of PBMCs, and another without edema and with high AACII, undetectable TNF-alpha, low APB in the synovial fluid and blood plasma and high APB in the membrane-bound fraction of PBMCs. Data suggest that APB and CIA are strongly related. (C) 2011 Elsevier B.V. All rights reserved.

Gudinnan Hathor : en studie ur metallurgiverksamhetens perspektiv som belyser auktoritära strukturer i forna Egypten

Denna studie undersöker gudinnan Hathors funktion i forna Egypten med utgångspunkt från metallurgiverksamheten som Hathor var beskyddare över. Studien undersöker vad för behov som uppstår i metallurgikontexten och hur denna kan ha påverkat och speglats i förställningar kring gudinnan Hathors funktion i forna Egypten. Studien stödjer sig på William Padens teori om religiösa Världar för att därigenom belysa hur behov i en specifik kontext kan spelgas i den Religiösa Världen. Undersökningen baseras på tolkningar av en rad olika forskningsrapporter. Dels etnografiska dokumentationer om metallurgikontexter ifrån Afrika söder om Sahara, arkeologiska utgrävningar från gruvområdet i Timna i Sinai och forskares interpretationer kring gudinnan Hathors funktion i forna Egypten. Ifrån metallurgiverksamheten studerades dels hur den äldre teknologin fungerade och hur den inverkade på religiösa föreställningar och den auktoritära strukturen i Afrika. Därtill vad för sorts belägg som finns för metallurgiverksamhet i Timna i Sinai och hur gudinnan Hathors kults närvaro i gruvområdet kom till uttryck. Dessutom studeras forskares interpretationer som rör gudinnan Hathors kults funktion, auktoritära struktur och kultens förhållande till konungen i forna Egypten. Dessa uppgifter analyserades därefter och studien visar starka indikationer på att gudinnan Hathor skapades och användes i syfte att gagna en begränsad grupps intresse i forna Egypten. Att gudinnan Hathors funktion och de offentliga festivalerna var till för att upprätthålla en auktoritär struktur och vidmakthålla smidessläktets och prästerskapets makt.

A utilização de varões de GFRP nas estruturas de betão armado

A crescente preocupação com a deterioração e consequente reparação e reabilitação das estruturas de betão armado tradicionais, sobretudo devido ao fenómeno da corrosão associada aos varões de aço, que afecta significativamente a durabilidade deste tipo de estruturas, tem impulsionado a introdução dos varões de GFRP na área da engenharia civil. A progressiva utilização dos varões de GFRP, nas estruturas de betão armado, surge não só no sentido de colmatar as deficiências apresentadas pelo aço convencional, mas igualmente, pelas características que lhe são inerentes, das quais se destacam, entre outras, a elevada resistência à tracção e à fadiga, a elevada resistência química, a sua não condutividade electromagnética e corrosibilidade nula e o seu baixo peso próprio. Contudo, o comportamento frágil consequente do reduzido módulo de elasticidade, o custo início elevado e a falta de códigos de dimensionamento, têm tardado a sua aplicação generalizada. Neste contexto, procede-se no presente documento à elaboração de um Estado da Arte, com intuito de analisar o ponto de situação dos conhecimentos, seguida da apresentação da filosofia de dimensionamento e da descrição das propriedades físicas e mecânicas dos varões de GFRP. No sentido de avaliar o Estado Limite Último (E.L.U.) e o Estado Limite de Serviço (E.L.S.), dos elementos de betão armado com GFRP, realiza-se uma exposição dos modelos de dimensionamento sugeridos pelo ACI 440.1R-06 [3], pelo Fib-Bulletin 40 [21] e pelo ISIS Manual No.3 [25]. Por fim, dimensiona-se três elementos estruturais de betão armado com GFRP, com o objectivo de delinear as principais diferenças entre as armaduras de aço e de GFRP. Os exemplos de aplicação efectuados permitiram concluir, que de facto, o E.L.S. é maioritariamente condicionante neste tipo de estruturas, devido ao reduzido módulo de elasticidade, que afecta significativamente a deformação.

A oficina como método de desenvolvimento de projeto do produto aplicado à atividade jangadeira de Ponta Negra Natal-RN

The jangadas (brazilian fishing rafts) are rudimentary artisanal vessels intrinsic to the Northeast of Brazil. The fishery with jangadas is highly representative in the State of Rio Grande do Norte, and source of income for many families in addition to being a strong cultural icon. Is still alive despite the difficulties, bringing the history and customs of the fishermen and their people. However, is in process of extinction due to factors such as the low profitability of the activity, tourism and urbanization. From the understanding of activity involving their context and circumstances, based on identified problems regarding the conditions of use of jangadas as the unpredictability, the risk of accidents, poor working conditions, hygiene and housing, this dissertation aims to: analyzing the design of the jangada on the beach of Ponta Negra and its relationship with the activity in relation to health, safety, productivity and environment, and from such assessments, together with the results achieved during the workshops of the project, proposing a cart to move the raft, adapted to the local fisherman activity studied. To perform analysis of jangadeira activity, we used a methodology based on ergonomic work analysis - AET (WISNER, 1987; GUÈRIN, 2001; VIDAL, 2008, SALDANHA, 2004 and Carvalho, 2005). For data collection were used observational and interaction methods as a conversational action, verbalizations, photographs and video. It is emphasized that the search for solutions appropriate to the jangadeira activity was possible through the collaboration of several people, not just an informational level and understanding during the work activity, but effectively contributing to the making decisions

Estudo das propriedades psicométricas da escala WHOQOLold em idosos da região Nordeste

The population aging process increases the number of elderly people worldwide. In Brazil, a country of continental size, this process began in the 40s and happens with specific features in each of the different region s realities. This way, this thesis aimed to evaluate the psychometric properties of a elderly s quality of life (QOL) scale, the WHOQOL-old, in a population of the Northeast of Brazil. We sought to investigate the congruence between the content covered by the scale and the ones deemed as relevant by the participants. It aimed also study the validity evidences of the instrument s internal structure. To achieve the research objectives we adopted the design of multiple methods. The research was organized in two studies. For data collection, both studies used a sociodemographic questionnaire to obtain a profile of the participants and the Mini Mental State Exam (MMSE), used as exclusion criterion. A number of 18 elderly residents of the cities of Natal-RN and Campina Grande-PB, mean age of 73.3 years (SD = 5.9) took part od the study, They were organized into three focal groups (FG) in witch they discussed about the concept of QOL, what enhance and what hinders QOL. For Study II, a quantitative approach, 335 elderly from Campina Grande responded scale WHOQOL-old. They are between 65 and 99 years (M = 74.17, SD = 6.5). The FG data were analyzed by categorical thematic content. For the data analysis of the WHOQOL-old scale were used exploratory factor analysis and calculation of the Akaike and Bayesian information criteria. The results of both studies were triangulated. According to the discussions in the FG, health and social participation have central roles in quality of life. Social participation is related to all the other QOL s influences raised. The participants indicated the relevance of religiosity and were divided about the importance of sexual activity. Exploratory factor analysis (EFA) extracted a model of six factors. Two items (OLD_3 and OLD_9), not loaded on any factor and were excluded. The other items had factor loadings > 0.3. The response categories were reduced from five to three. After the scale changes, the empirical model showed better fit (-2loglikelihood = 8993.90, BIC and AIC = 9183.90 = 9546.24) than the theoretical model (-2loglikelihood = 18390.88, AIC = 18678.88 and BIC = 19228.11). Despite the best information criterion values, the RMESA remained above the ideal (0.06). We conclude that the WHOQOL-old presents psychometric parameters below the ideal when used with the Northeast population, but the improvements made the scale s use acceptable. The WHOQOL-old uses observable variables that matches with the participants' perceptions on quality of life. However, new strategies must be tested for a better sacale refinement
