Silvia Pellicer-Ortin, Eva Figes' Writings. A Journey through Trauma
No full textWriting a monograph on such a confidential author as Eva Figes – whose name has long been hardly known – is certainly an exciting yet daunting task. Since Eva Figes passed away in London in late August 2012 (somewhat unnoticedly, as could be expected, in the academic world), and even before that, writing about her work has appeared to her devotees not only as a necessary tribute to a fine author but also as an attempt to shore substantial fragments against what may otherwise turn into ruins: ..

Análise da relação entre o EVA, o MVA e outros indicadores de desempenho das empresas da BM&FBovespa no período de 2000 a 2010
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Sócio Econômico, Programa de Pós-Graduação em Contabilidade, Florianópolis, 2012Este estudo tem por objetivo evidenciar a relação entre o EVA, o MVA e outros indicadores de desempenho das empresas listadas na BM&FBovespa no período de 2000 a 2010. A pesquisa se justifica pela relevância da mensuração do desempenho empresarial e da necessidade de informações que evidenciem a geração de valores aos acionistas, nesse sentido, na literatura o EVA e o MVA se destacam como possibilidade para medir a geração de riquezas aos investidores e a valorização das ações. O estudo tem como amostra 196 empresas listadas na BM&FBovespa, com dados do período de 2000 a 2010 disponíveis na base do Economática®. De posse dos dados foi utilizado uma estimativa econométrica de painel dinâmico, no qual acompanhou-se ao longo do tempo 196 empresas durante dez períodos. Para analisar a relação entre as variáveis explicativas com o MVA utilizou-se o estimador GMM de Arellano e Bond (1991) e do teste de causalidade de Granger para evidenciar estatísticamente o sentido de causa entre as variáveis estudadas. Os resultados alcançados permitem-nos identificar a relação entre o desempenho do EVA com o MVA das empresas. Bem como, testou-se se há relação de causalidade entre as variáveis, sendo possível constatar que EVA é Granger-causa de MVA sendo uma relação bidirecional. A análise relacionou o desempenho do LPA, ROE, ROA e VM com o MVA das empresas da amostra. Os resultados evidenciaram que há relação entre as variáveis LPA e VM com o MVA das empresas. No entanto não foi possível confirmar a relação entre ROA e ROE com o MVA das empresas da amostra por meio da análise de dados em painel conforme o Modelo de Arellano e Bond (1991) e os resultados obtidos pela estatística F. Os resultados confirmam a base teórica da eficiência do EVA e do MVA como medidas de apoio ao processo de gestão, na identificação da geração ou destruição de riquezas para os acionistas, servindo como indicativos preditivos para a análise do desempenho empresarial.Abstract : This study aims to analyze the relationship between EVA, MVA and other performance measures of companies listed on the BM&FBovespa in the period from 2000 to 2010. The research is justified by the importance of performance measurement and the need for business information showing the generation of shareholder value, in this sense, literature EVA and MVA stands out as a possibility to measure the generation of wealth for investors and the valuation of shares . The study has a sample size of 196 companies listed on the BM&FBovespa, with data for the period 2000 to 2010 on the basis of available Economática®. In possession of data was used an econometric estimate of dynamic panel, which is followed over time companies 196 for ten periods. To analyze the relationship between the explanatory variables with the MVA used the GMM estimator of Arellano and Bond (1991) and Granger causality test to statistically demonstrate the meaning of cause between variables. The results allow us to identify the relationship between the performance of EVA with MVA companies. As well, we tested whether there is a causal link between the variables, and can see that EVA is Granger-cause of MVA is a bidirectional relationship. The analysis related the performance of LPA, ROE, ROA and VM with the MVA of the sample companies. The results showed that there is a relationship between variables LPA and VM with MVA companies. However it was not possible to confirm the relationship between ROA and ROE with the MVA of the sample by analyzing panel data model as the Arellano and Bond (1991) and the results obtained by the statistic F. The results confirm the theoretical efficiency of EVA and MVA as measures to support the management process, the identification of the generation or destruction of wealth for shareholders, serving as indicative predictive analysis of business performance

Viajantes ex-cêntricas nas histórias de Ana Miranda
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em Literatura.No conjunto das narrativas ficcionais da escritora brasileira Ana Miranda, a temática da viagem # considerada uma das mais férteis da literatura ocidental de todos os tempos # ocupa um espaço de centralidade, podendo até mesmo ser vista como o mais importante eixo de estruturação de suas obras. O estudo realizado pela presente tese tem por objetivo analisar o tratamento dado ao tema da viagem nos romances Desmundo, O retrato do rei, Dias & Dias e Amrik, evidenciando que por intermédio das narradora-viajantes # Oribela, Mariana, Feliciana e Amina # a autora promove um diálogo entre diferentes culturas, gêneros, etnias e gerações, ao mesmo tempo em que estabelece um profícuo diálogo com o passado em sua invariante problematização concernente aos limites e cruzamentos entre o discurso ficcional e os discursos narrativos extraliterários que o cercam, sobretudo o histórico e o biográfico. In the whole of Brazilian writer Ana Miranda#s fictional narrative, the travel thematic # considered one of the most fertile themes of the western literature of all times # occupies a central space, and can even been seen as the most important structuring axis of Miranda#s works. The aim of the present thesis is to analyze the treatment given to the travel subject in the novels Desmundo, O retrato do rei, Dias & Dias and Amrik, emphasizing that, through the traveling narrators, Oribela, Mariana, Feliciana and Amina, the author promotes a connection between different cultures, genders, ethnics and generations, at the same time that establishes a profitable dialogue with the past in her invariant problematization concerning the limits and crossings between the fictional and the extra-literary narrative discourses that surrounds it, mainly the historical and the biographic ones
Reduction theory for singular symplectic manifolds and singular forms on moduli spaces
No full text© 2023 The Author(s). Published by Elsevier Inc. This is an open access article under the CC BY-NC-ND licenseThe investigation of symmetries of b-symplectic manifolds and folded-symplectic manifolds is well-understood when the group under consideration is a torus (see, for instance, [25,21, 28] for b-symplectic manifolds and [12,14] for folded symplec-tic manifolds). However, reduction theory has not been set in this realm in full generality. This is fundamental, among other reasons, to advance in the “quantization commutes with reduction” programme for these manifolds initiated in [29,30].The project that gave rise to these results received the support of a fellowship from “la Caixa” Foundation (ID 100010434) under the INPHINIT 2018 program for excellence centers. The grant is attached to the retained excellence project Interactions between symmetries and singularities in Geometry and Physics supervised by Eva Miranda. The fellowship code is LCF/BQ/DI18/11660046.
