Entre o matrimônio, a beleza, a moda e esportes : imagens da mulher na Revista Vida Capichaba (1925-1939)

Essa dissertação tem por objetivo de estudo investigar as imagens do feminino presentes na revista Vida Capichaba, periódico de publicação quinzenal que circulou, no Estado do Espírito Santo, entre as décadas de 1920 e 1950. Diante da longevidade do periódico, optamos por concentrar nossos esforços analíticos nas décadas de 1920 e 1930, especificamente entre os anos de 1925 e 1939. Entendemos que o ideal de mulher presente na revista passou pela construção de requisitos morais e uma formação adequada para desempenhar papéis concebidos como naturalmente femininos como o casamento e a maternidade. Além dessa característica, outras práticas se fizeram ainda mais destacadas. A construção da beleza, de um corpo magro e jovem associado à valorização dos esportes e da moda, se tornaram características da nova mulher capixaba. Eficiência e delicadeza, sensualidade e obediência, maternidade e independência, agilidade e elegância, beleza e liberdade. São dualidades como essas, nas quais códigos sociais tradicionais e novos valores culturais se articulam definindo novos modos de ser, que compuseram o quadro de imagens presente na Vida Capichaba.

On the Suitability of Suffix Arrays for Lempel-Ziv Data Compression

Lossless compression algorithms of the Lempel-Ziv (LZ) family are widely used nowadays. Regarding time and memory requirements, LZ encoding is much more demanding than decoding. In order to speed up the encoding process, efficient data structures, like suffix trees, have been used. In this paper, we explore the use of suffix arrays to hold the dictionary of the LZ encoder, and propose an algorithm to search over it. We show that the resulting encoder attains roughly the same compression ratios as those based on suffix trees. However, the amount of memory required by the suffix array is fixed, and much lower than the variable amount of memory used by encoders based on suffix trees (which depends on the text to encode). We conclude that suffix arrays, when compared to suffix trees in terms of the trade-off among time, memory, and compression ratio, may be preferable in scenarios (e.g., embedded systems) where memory is at a premium and high speed is not critical.

Return premiums of sustainable companies listed on the Spanish stock market

The purpose of this paper is to analyze whether companies with a greater commitment to corporate social responsibility (SRI companies) perform differently on the stock market compared to companies that disregard SRI. Over recent years, this relationship has been taken up at both a theoretical and practical level, and has led to extensive scientific research of an empirical nature involving the examination of the relationships existing between the financial and social, environmental and corporate governance performance of a company and the relationship between SRI and investment decisions in the financial market. More specifically, this work provides empirical evidence for the Spanish market as to whether or not belonging to a group of companies the market classes as sustainable results in return premiums that set them apart from companies classed as conventional, and finds no differences in the stock market performance of companies considered to be SRI or conventional.

The risk-return trade-off in Europe: A temporal and cross-sectional analysis

This paper analyzes the risk-return trade-off in European equities considering both temporal and cross-sectional dimensions. In our analysis, we introduce not only the market portfolio but also 15 industry portfolios comprising the entire market. Several bivariate GARCH models are estimated to obtain the covariance matrix between excess market returns and the industrial portfolios and the existence of a risk-return trade-off is analyzed through a cross-sectional approach using the information in all portfolios. It is obtained evidence for a positive and significant risk-return trade-off in the European market. This conclusion is robust for different GARCH specifications and is even more evident after controlling for the main financial crisis during the sample period.

Optimal insurance with counterparty default risk

We study the design of optimal insurance contracts when the insurer can default on its obligations. In our model default arises endogenously from the interaction of the insurance premium, the indemnity schedule and the insurer’s assets. This allows us to understand the joint effect of insolvency risk and background risk on efficient contracts. The results may shed light on the aggregate risk retention sched- ules observed in catastrophe reinsurance markets, and can assist in the design of (re)insurance programs and guarantee funds.

What drives corporate default risk premia? Evidence from the CDS market

This paper studies the evolution of the default risk premia for European firms during the years surrounding the recent credit crisis. We employ the information embedded in Credit Default Swaps (CDS) and Moody’s KMV EDF default probabilities to analyze the common factors driving this risk premia. The risk premium is characterized in several directions: Firstly, we perform a panel data analysis to capture the relationship between CDS spreads and actual default probabilities. Secondly, we employ the intensity framework of Jarrow et al. (2005) in order to measure the theoretical effect of risk premium on expected bond returns. Thirdly, we carry out a dynamic panel data to identify the macroeconomic sources of risk premium. Finally, a vector autoregressive model analyzes which proportion of the co-movement is attributable to financial or macro variables. Our estimations report coefficients for risk premium substantially higher than previously referred for US firms and a time varying behavior. A dominant factor explains around 60% of the common movements in risk premia. Additionally, empirical evidence suggests a public-to-private risk transfer between the sovereign CDS spreads and corporate risk premia.

Idiosyncratic risk really drives stock returns; Spanish evidence

Following the theoretical model of Merton (1987), we provide a new perspective of study about the role of idiosyncratic risk in the asset pricing process. More precisely, we analyze whether the idiosyncratic risk premium depends on the idiosyncratic risk level of an asset as well as the vatriation in the market-wide measure of idiosyncratic risk. As expected, we obtain a net positive risk premium for the Spanish stock market over the period 1987-2007. Our results show a positive relation between returns and individual indiosyncratic risk levels and a negative but lower relation with the aggregate measure of idiosyncratic risk. These findings have important implications for portfolio and risk management and contribute to provide a unified and coherent answer for the main and still unsolved question about the idiosyncratic risk puzzle: whether or not there exists a premium associated to this kind of risk and the sign for this risk premium.

Sistema de suporte à decisão de anteprojecto de mini-hídrica

O presente documento tem como principal objectivo efectuar uma abordagem aos diversos aspectos que constituem um Sistema de Suporte à Decisão de um Anteprojecto de Centrais Mini-Hídricas. A energia é, nos dias de hoje, um dos temas políticos com mais relevância para a nossa sociedade, muito em particular para os países que não dispõem de recursos energéticos de origem fóssil. O preço do petróleo e seus derivados tem tendência para aumentar, embora possa ter períodos de decréscimo; a escassez associada a estes recursos tenderá a originar uma futura escalada de preços. Com a crescente preocupação com o ambiente, nomeadamente com as emissões de gases poluentes, devido à utilização de combustíveis fósseis para gerar electricidade, é cada vez mais imperioso optar por recursos com menor impacte ambiental e, de preferência, renováveis. A promoção e a utilização de fontes de energia renováveis para a produção energética resultam da necessidade de garantir um desenvolvimento sustentável para a sociedade actual e futura, sendo a energia hídrica uma boa solução alternativa. Após uma análise das questões técnicas e económicas relacionadas com as Centrais Mini-Hídricas, foi utilizada uma aplicação informática, Solver Premium®, que tem como suporte o Excel®, visando a maximização do potencial hidroeléctrico e a respectiva viabilidade económica entre vários cenários colocados para um pequeno aproveitamento hídrico em estudo. Os estudos de viabilidade são uma mais-valia para um agente de decisão; com a informação replicada pela aplicação informática utilizada, é possível obter com rapidez e uma curta margem de erro a decisão do melhor investimento, considerando várias hipóteses no projecto em análise.

Eastwards / westwards: which direction for gender studies in the 21st century?

Eastwards / Westwards: Which Direction for Gender Studies in the XXIst Century? is a collection of essays which focus on themes and methods that characterize current research into gender in Asian countries in general. In this collection, ideas derived from Gender Studies elsewhere in the world have been subjected to scrutiny for their utility in helping to describe and understand regional phenomena. But the concepts of Local and Global – with their discoursive productions – have not functioned as a binary opposition: localism and globalism are mutually constitutive and researchers have interrogated those spaces of interaction between the ‘self’ and the ‘other’, bearing in mind their own embeddedness in social and cultural structures and their own historical memory. Contributors to this collection provided a critical transnational perspective on some of the complex effects of the dynamics of cultural globalization, by exploring the relation between gender and development, language, historiography, education and culture. We have also given attention to the ideological and rhetorical processes through which gender identity is constructed, by comparing textual grids and patterns of expectation. Likewise, we have discussed the role of ethnography, anthropology, historiography, sociology, fiction, popular culture and colonial and post-colonial sources in (re)inventing old/new male/female identities, their conversion into concepts and circulation through time and space. This multicultural and trans-disciplinary selection of essays is totally written in English, fully edited and revised, therefore, it has a good potential for an immediate international circulation. This project may trace new paths and issues for discussion on what concerns the life, practices and narratives by and about women in Asia, as well as elsewhere in the present day global experience. Academic readership: Researchers, scholars, educators, graduate and post-graduate students, doctoral students and general non-fiction readers, with a special interest in Gender Studies, Asia, Colonial and Post-Colonial Literature, Anthropology, Cultural Studies, History, Historiography, Politics, Race, Feminism, Language, Linguistics, Power, Political and Feminist Agendas, Popular Culture, Education, Women’s Writing, Religion, Multiculturalism, Globalisation, Migration. Chapter summary: 1. “Social Gender Stereotypes and their Implication in Hindi”, Anjali Pande, Jawaharlal Nehru University, New Delhi, India. This essay looks at the subtle ways in which gender identities are constructed and reinforced in India through social norms of language use. Language itself becomes a medium for perpetuating gender stereotypes, forcing its speakers to confirm to socially defined gender roles. Using examples from a classroom discussion about a film, this essay will highlight the underlying rigid male-female stereotypes in Indian society with their more obvious expressions in language. For the urban woman in India globalisation meant increased economic equality and exposure to changed lifestyles. On an individual level it also meant redefining gender relations and changing the hierarchy in man-­woman relationships. With the economic independence there is a heightened sense of liberation in all spheres of social life, a confidence to fuzz the rigid boundaries of gender roles. With the new films and media celebrating this liberated woman, who is ready to assert her sexual needs, who is ready to explode those long held notions of morality, one would expect that the changes are not just superficial. But as it soon became obvious in the course of a classroom discussion about relationships and stereotypes related to age, the surface changes can not become part of the common vocabulary, for the obvious reason that there is still a vast gap between the screen image of this new woman and the ground reality. Social considerations define the limits of this assertiveness of women, whereas men are happy to be liberal within the larger frame of social sanctions. The educated urban woman in India speaks in favour of change and the educated urban male supports her, but one just needs to scratch the surface to see the time tested formulae of gender roles firmly in place. The way the urban woman happily balances this emerging promise of independence with her gendered social identity, makes it necessary to rethink some aspects of looking at gender in a gradually changing, traditional society like India. 2. “The Linguistic Dimension of Gender Equality”, Alissa Tolstokorova, Kiev Centre for Gender Information and Education, Ukraine. The subject-matter of this essay is gender justice in language which, as I argue, may be achieved through the development of a gender-related approach to linguistic human rights. The last decades of the 20th century, globally marked by a “gender shift” in attitudes to language policy, gave impetus to the social movement for promoting linguistic gender equality. It was initiated in Western Europe and nowadays is moving eastwards, as ideas of gender democracy progress into developing countries. But, while in western societies gender discrimination through language, or linguistic sexism, was an issue of concern for over three decades, in developing countries efforts to promote gender justice in language are only in their infancy. My argument is that to promote gender justice in language internationally it is necessary to acknowledge the rights of women and men to equal representation of their gender in language and speech and, therefore, raise a question of linguistic rights of the sexes. My understanding is that the adoption of the Universal Declaration of Linguistic Rights in 1996 provided this opportunity to address the problem of gender justice in language as a human rights issue, specifically as a gender dimension of linguistic human rights. 3. “The Rebirth of an Old Language: Issues of Gender Equality in Kazakhstan”, Maria Helena Guimarães, Polytechnic Institute of Porto, Portugal. The existing language situation in Kazakhstan, while peaceful, is not without some tension. We propose to analyze here some questions we consider relevant in the frame of cultural globalization and gender equality, such as: free from Russian imperialism, could Kazakhstan become an easy prey of Turkey’s “imperialist dream”? Could these traditionally Muslim people be soon facing the end of religious tolerance and gender equality, becoming this new old language an easy instrument for the infiltration in the country of fundamentalism (it has already crossed the boarders of Uzbekistan), leading to a gradual deterioration of its rich multicultural relations? The present structure of the language is still very fragile: there are three main dialects and many academics defend the re-introduction of the Latin alphabet, thus enlarging the possibility of cultural “contamination” by making the transmission of fundamentalist ideas still easier through neighbour countries like Azerbaijan, Uzbekistan and Turkmenistan (their languages belong to the same sub-group of Common Turkic), where the Latin alphabet is already in use, and where the ground for such ideas shown itself very fruitful. 4. “Construction of Womanhood in the Bengali Language of Bangladesh”, Raasheed Mahmood; University of New South Wales, Sydney. The present essay attempts to explore the role of gender-based language differences and of certain markers that reveal the status accorded to women in Bangladesh. Discrimination against women, in its various forms, is endemic in communities and countries around the world, cutting across class, race, age, and religious and national boundaries. One cannot understand the problems of gender discrimination solely by referring to the relationship of power or authority between men and women. Rather one needs to consider the problem by relating it to the specific social formation in which the image of masculinity and femininity is constructed and reconstructed. Following such line of reasoning this essay will examine the nature of gender bias in the Bengali language of Bangladesh, holding the conviction that as a product of social reality language reflects the socio-cultural behaviour of the community who speaks it. This essay will also attempt to shed some light on the processes through which gender based language differences produce actual consequences for women, who become exposed to low self-esteem, depression and systematic exclusion from public discourse. 5. “Marriage in China as an expression of a changing society”, Elisabetta Rosado David, University of Porto, Portugal, and Università Ca’Foscari, Venezia, Italy. In 29 April 2001, the new Marriage Law was promulgated in China. The first law on marriage was proclaimed in 1950 with the objective of freeing women from the feudal matrimonial system. With the second law, in 1981, values and conditions that had been distorted by the Cultural Revolution were recovered. Twenty years later, a new reform was started, intending to update marriage in the view of the social and cultural changes that occurred with Deng Xiaoping’s “open policy”. But the legal reform is only the starting point for this case-study. The rituals that are followed in the wedding ceremony are often hard to understand and very difficult to standardize, especially because China is a vast country, densely populated and characterized by several ethnic minorities. Two key words emerge from this issue: syncretism and continuity. On this basis, we can understand tradition in a better way, and analyse whether or not marriage, as every social manifestation, has evolved in harmony with Chinese culture. 6. “The Other Woman in the Portuguese Colonial Empire: The Case of Portuguese India”, Maria de Deus Manso, University of Évora, Portugal. This essay researches the social, cultural and symbolic history of local women in the Portuguese Indian colonial enclaves. The normative Portuguese overseas history has not paid any attention to the “indigenous” female populations in colonial Portuguese territories, albeit the large social importance of these social segments largely used in matrimonial and even catholic missionary strategies. The first attempt to open fresh windows in the history of this new field was the publication of Charles Boxer’s referential study about Women in lberian Overseas Expansion, edited in Portugal only after the Revolution of 1975. After this research we can only quote some other fragmentary efforts. In fact, research about the social, cultural, religious, political and symbolic situation of women in the Portuguese colonial territories, from the XVI to the XX century, is still a minor historiographic field. In this essay we discuss this problem and we study colonial representations of women in the Portuguese Indian enclaves, mainly in the territory of Goa, using case studies methodologies. 7. “Heading East this Time: Critical Readings on Gender in Southeast Asia”, Clara Sarmento, Polytechnic Institute of Porto, Portugal. This essay intends to discuss some critical readings of fictional and theoretical texts on gender condition in Southeast Asian countries. Nowadays, many texts about women in Southeast Asia apply concepts of power in unusual areas. Traditional forms of gender hegemony have been replaced by other powerful, if somewhat more covert, forms. We will discuss some universal values concerning conventional female roles as well as the strategies used to recognize women in political fields traditionally characterized by male dominance. Female empowerment will mean different things at different times in history, as a result of culture, local geography and individual circumstances. Empowerment needs to be perceived as an individual attitude, but it also has to be facilitated at the macro­level by society and the State. Gender is very much at the heart of all these dynamics, strongly related to specificities of historical, cultural, ethnic and class situatedness, requiring an interdisciplinary transnational approach.

Voices in search of a reader: the polyphonic writing of António Lobo Antunes

This paper aims at analysing the writing of the Portuguese author António Lobo Antunes, considered one of the major writers in European Literature with 26 books published, by focusing on the strategies deployed in his texts of creating micro-narratives within the main frame, and conveying the elements of individual and collective memory, past and present, the self and the others, using various voices and silences. Lobo Antunes incorporates in his writing his background as a psychiatrist at a Mental Hospital in Lisbon, until 1985 (when he decided to commit exclusively to writing), his experience as a doctor in the Portuguese Colonial War battlefield, but also the daily routines of the pre and post 25th of April 1974 (Portuguese Revolution) with subtle and ironic details of the life of the middle and upper class of Lisbon‘s society: from the traumas of the war to the simple story of the janitor, or the couple who struggles to keep their marriage functional, everything serves as material to develop and interweave a complex plot, that a lot of readers find too enwrapped and difficult to follow through. Some excerpts taken from his first three novels and books of Chronicles and his later novel – Ontem não te Vi em Babilónia (2006) – will be put forward to exemplify the complexity of the writing and the main difficulties of the reader, lost in a multitude of narrators‘ voices. Recently, Lobo Antunes has commented on his work stating: What I write can be read in the darkness. This paper aims at throwing some light by unfolding some of the strategies employed to defy new borders in the process of reading.

A celebração do casamento do Príncipe Carlos com Camilla Parker Bowles: mediação e mediatização

Tendo presente a relação que o discurso estabelece com a sociedade como um todo, este artigo procura analisar o modo como a monarquia britânica representou o segundo casamento do Príncipe Carlos e o modo como os media construíram os relatos do acontecimento desde 10 de Fevereiro a 9 de Abril de 2005 relativamente a assuntos mais vastos, como sejam as relações de poder, as estruturas económicas dos jornais e a cultura popular. Foi dada particular relevância aos aspectos multifuncionais do discurso (por exemplo, as funções ideacional, interpessoal e textual), o que requer uma leitura contextualizada de um duplo processo de mediação: por um lado, a organização da cerimónia levada a cabo pelo Palácio de St. James e a sua subsequente estratégia para atingir um fechamento monológico e, por outro, as representações discursivas da imprensa britânica, abertas a uma polifonia de vozes e a vários enquadramentos discursivos.

The wedding of Prince Charles and Camilla Parker-Bowles: royal mediation and press mediatization

Bearing in mind the relationship between discourse and society at large, this article addresses the way the British monarchy represented Charles’s second marriage and the way the media constructed their accounts in the period from 10 February (announcement) until 9 April 2005 (wedding) in relation to wider issues such as power relations, newspaper economic structures and popular culture. Particular attention is paid to the multifunctional features of discourse (i.e. its ideational, interpersonal and textual functions), which requires a contextualized reading of a dual process of mediation: on the one hand, the staging of the ceremony by St. James’s Palace and its strategy for attaining monologic closure and, on the other hand, discursive representations by the British press open to a polyphony of voices and discursive frames

Enabling inter-domain transactions in bridge-based hybrid wired/wireless PROFIBUS networks

The marriage of emerging information technologies with control technologies is a major driving force that, in the context of the factory-floor, is creating an enormous eagerness for extending the capabilities of currently available fieldbus networks to cover functionalities not considered up to a recent past. Providing wireless capabilities to such type of communication networks is a big share of that effort. The RFieldbus European project is just one example, where PROFIBUS was provided with suitable extensions for implementing hybrid wired/wireless communication systems. In RFieldbus, interoperability between wired and wireless components is achieved by the use specific intermediate networking systems operating as repeaters, thus creating a single logical ring (SLR) network. The main advantage of the SLR approach is that the effort for protocol extensions is not significant. However, a multiple logical ring (MLR) approach provides traffic and error isolation between different network segments. This concept was introduced in, where an approach for a bridge-based architecture was briefly outlined. This paper will focus on the details of the inter-Domain Protocol (IDP), which is responsible for handling transactions between different network domains (wired or wireless) running the PROFIBUS protocol.

Accionamentos eficientes de força‐motriz. Nova classificação

Os motores eléctricos, particularmente o motor assíncrono de indução, são o tipo de máquina mais utilizada na indústria em virtude da sua grande versatilidade, gama de potências, robustez, duração, reduzida manutenção, baixa poluição, facilidade de produção e custos de aquisição relativamente baixos. Como qualquer máquina, o motor eléctrico, responsável pela conversão de energia eléctrica em mecânica, apresenta perdas. O rendimento (ou eficiência) é definido como sendo a razão entre a potência de saída (ao nível do veio de saída do accionamento) e a potência eléctrica absorvida à entrada. A produção de energia mecânica, através da utilização de motores eléctricos, absorve cerca de 60% da energia eléctrica consumida no sector industrial do nosso País, da qual apenas metade é energia útil. Este sector é, pois, um daqueles em que é preciso tentar fazer economias, prioritariamente. Os sistemas de accionamentos têm que ser abordados como um todo, já que a existência de um componente de baixo rendimento influencia drasticamente o rendimento global. O êxito neste domínio depende, em primeiro lugar, da melhor adequação da potência do motor à da máquina que ele acciona. Quando o regime de funcionamento é muito variável para permitir este ajustamento, pode‐se equipar o motor com um conversor electrónico de variação de velocidade. Outra possibilidade é a utilização dos motores “ de perdas reduzidas”, de “alto rendimento”, ou “elevada eficiência”, que permitem economias energéticas consideráveis. Nos últimos anos, muitos fabricantes de motores investiram fortemente na pesquisa e desenvolvimento de novos produtos com o objectivo de colocarem no mercado motores mais eficientes. O acordo voluntário obtido em 1999 entre a CEMEP (Associação Europeia de Fabricantes de Motores Eléctricos) e a Comissão Europeia sobre o rendimento de motores de 2 e 4 pólos, na gama de potências 1,1 a 90 kW, foi revisto em 2004. Os motores foram classificados de acordo com o seu rendimento: ‐ EFF1 – Motores de alto rendimento; ‐ EFF2 – Motores de rendimento aumentado; ‐ EFF3 – Motores sem qualquer requisito especial. No seguimento da directiva "Eco‐design Directive (2005/32/CE) “ publicada em 2005 para Produtos que consomem energia (EUP), a Comissão Europeia aprovou em Julho de 2009 um regulamento de aplicação dos requisitos de concepção ecológica para os motores eléctricos, com efeitos a partir de meados de 2011, dando aos fabricantes de cerca de 2 anos para garantir que seus produtos cumprem a referida directiva. O lote 11 da Directiva EUP (Energy Using Products) descreve as orientações de design, a compatibilidade ambiental, o impacte ambiental e o consumo de energia de máquinas / motores eléctricos rotativos de alto rendimento. A directiva abrange os motores de 2, 4 e 6 pólos, na gama de potências de 0,75 a 375 kW. Neste âmbito, os motores passam a ser classificados por: ‐ IE1 (igual a EFF2) – com utilização proibida; ‐ IE2 (igual a EFF1) – com utilização obrigatória; ‐ IE3 (igual a Premium) – com utilização voluntária; ‐ IE4 (ainda não aplicável a accionamentos assíncronos).
