Processo criativo que (se) contamina e (se) ocupa: nos ‘entres’ de dança, vídeo e cidade

Na arte contemporânea, as videodanças contribuem para difusão da arte, visibilidade e sustentabilidade de obras, além de borrarem fronteiras, permitindo que linguagens artísticas interajam, cruzem e estabeleçam interfaces. Dentre processos intermidiáticos em artes cênicas, a videodança se destaca como linguagem híbrida e resultado do diálogo entre dança e vídeo. Assim, tecnologias digitais dialogam com poéticas da dança, diferindo-se do registro videográfico. Refletimos aspectos processuais, poéticas, estratégias e dispositivos nas interfaces entre dança, vídeo e espaço urbano na criação de uma videodança em Cataguases (Minas Gerais, Brasil). Focamos, a partir da investigação baseada na prática, na discussão do processo de criação da obra “Bárbara”. Observamos que ocorreu não somente a ocupação da cidade de arquitetura modernista pela dança e pela tecnologia digital (registro imagético). Todos esses agentes se contaminaram.info:eu-repo/semantics/publishedVersio

Revisiting 1-Copy equivalence in clustered databases

Recently renewed interest in scalable database systems for shared nothing clusters has been supported by replication protocols based on group communication that are aimed at seamlessly extending the native consistency criteria of centralized database management systems. By using a read-one/write-all-available approach and avoiding the fine-grained synchronization associated with traditional distributed locking, one needs just a single distributed interaction step for each update transaction. Therefore the system can easily be scaled to a large number of replicas, especially, with read intensive loads typical of Web server support environments.In this paper we point out that 1-copy equivalence for causal consistency, which is subsumed by both serializability and snapshot isolation criteria, depends on basic session guarantees that are costly to ensure in clusters, especially in a multi-tier environment. We then point out a simple solution that guarantees causal consistency in the Database State Machine protocol and evaluate its performance, thus highlighting the cost of seamlessly providing common consistency criteria of centralized databases in a clustered environment.(undefined

Cape verdean women's fertility - West Africa

Os níveis de fecundidade de um país fazem parte de um elenco de indicadores que orientam na formulação de políticas públicas, face à redução do volume da população e do seu envelhecimento. O aumento da fecundidade pode indicar falta de acesso da população a informações e serviços de saúde reprodutiva. Assim, o objetivo é analisar a fecundidade das mulheres cabo-verdianas e a contribuição de determinantes próximos da fecundidade. Realizou-se a análise e a mensuração do comportamento da fecundidade das mulheres a partir de métodos indiretos de estimação da fecundidade com base nos dados dos censos. A análise dos determinantes próximos da fecundidade é baseado no DHS (Pesquisa sobre Saúde e Demografia - 1998). Os dados mostraram uma redução de 1,7, 1,5 e 1,6 filhos por mulher no final do período reprodutivo, de acordo com os três métodos (Brass, Arriaga e Gompertz) entre 1990 e 2000. As taxas foram mais altas para as mulheres das áreas rurais. A fecundidade vem diminuindo no país e com ocorrência mais precoce. O uso de contraceptivos foi o determinante de maior relevância no processo de declínio de fecundidade das mulheres de Cabo Verde, África.A country's fertility levels are part of a list of indicators that guide the formulation of public policies, in view of population reduction and population aging. An increase in fertility may indicate the population's lack of access to reproductive health information and services. Therefore, our aim is to analyze Cape Verdean women's fertility and the contribution of proximal determinants of fertility. The analysis and measurement of the behavior of the women's fertility were performed through indirect methods of fertility estimation based on census data. The analysis of the parameters near fertility was based on DHS (1998). The data showed a reduction of 1.7, 1.5 and 1.6 children per woman at the end of the reproductive period according to the three methods (Brass, Arriaga and Gompertz) between 1990 and 2000. Rates were higher for women who lived in rural areas. Fertility has been decreasing in the country and the use of contraceptives was the most relevant parameter regarding the fertility decline process of women from Cape Verde, Africa

Fatores associados ao início da vida sexual e o uso de preservativo entre adolescentes da Ilha de Santiago, Cabo Verde, África Ocidental

Foram analisados fatores associados ao início da vida sexual de adolescentes na Ilha de Santiago, Cabo Verde, segundo sexo. Estudo realizado com amostra probabilística e representativa de 768 adolescentes, age 13-17 anos, de escolas secundárias públicas da Ilha de Santiago em 2007. A associação foi testada pelo teste de proporção, qui-quadrado de Pearson ou Fisher e regressão logística. Nos rapazes, os fatores associados ao início da vida sexual foram: idade maior que 14 anos, ser católico e consumo de bebidas alcoólicas. Para meninas: escolaridade maior que nove anos e ter parceiro afetivo-sexual. Ao contrário de outros contextos da África Subsaariana, foram constatadas taxas elevadas de uso de preservativo por adolescentes no início da vida sexual. Os adolescentes podem iniciar a vida sexual de maneira mais segura se tiverem informação, educação sexual e acesso a métodos de prevenção à gravidez e às DST. Este artigo oferece elementos para a reflexão sobre o delineamento de políticas de redução da vulnerabilidade dos jovens às DST/AIDS e sobre os limites e desafios da promoção do uso do preservativo e educação sexual, focando as relações desiguais de gêneroThe current study focuses on factors associated with sexual initiation and condom use among teenagers on Santiago Island, Cape Verde, according to gender. This was a representative, probabilistic sample of 13-to-17-year-olds (n = 768) attending public secondary schools on Santiago Island in 2007. Associations were tested by test of proportion, Pearson's chi-square, or Fisher's exact test and logistic regression. Factors related to sexual initiation among boys were: age over 14 years, Catholic religion, and alcohol consumption. For girls, the factors included: > 9 years of schooling and involvement in an affective-sexual relationship. Unlike other Sub-Saharan countries, this study showed a high prevalence of condom use during initial sexual activity. Adolescents are able to safely begin sexually active life if they have access to information, sex education, and other STD prevention and contraceptive methods. This study provides insights on the development of policies to reduce the vulnerability of the young population to STD/AIDS and the limits and challenges related to the promotion of condom use and sex education, focusing on unequal gender relation

Endanghed lives: a reflexion about the relation between gestations number and maternal mortality

Este estudo teve por objetivo identificar o risco e os fatores associados à mortalidade materna de multigestas (cinco ou mais gestações). Descreve a tendência da Taxa de Fecundidade Total (TFT) e da Razão de Mortalidade Materna (RMM) de 1998 a 2004 no Paraná. Apresenta uma análise dos 822 óbitos maternos deste período, o cálculo da Razão de Mortalidade Materna Específica, o Risco Relativo, a freqüência e o Odds Ratio para algumas variáveis segundo número de gestações. Analisa também as causas e a evitabilidade dos óbitos maternos. Os resultados apontaram TFT baixa (1,8 filhos por mulher) e a RMM elevada (69,7/100.000 nascidos vivos) no Paraná em 2004. Um quarto dos 822 óbitos maternos (206) era de multigestas (cinco ou mais gestações), o risco relativo de morte materna foi seis vezes superior do que para as mulheres com até duas gestações, e os perfis sociodemográfico e o reprodutivo foram mais desfavoráveis para aquele grupo de mulheres. A baixa escolaridade, a idade igual ou acima de 30 anos e o pré-natal com menos de quatro consultas apresentaram associação com o maior número de gestações. A proporção de mortes por causas obstétricas indiretas, hemorragias e aborto, foi maior entre as multigestas, e cerca de 90% dos óbitos deste grupo foi considerado evitável. Concluiu-se que o monitoramento das multigestas com idade avançada e em desvantagem social, bem como ações efetivas de planejamento familiar, e serviços obstétricos qualificados para gestação de alto risco são medidas que podem contribuir para a redução da mortalidade materna.This study had as objective to identify the risk and the factors associated to the multigesta's maternal mortality (gesta >; 5). It describes the tendency of the Total Fertility Rate (TFT) and of the Maternal Mortality Ratio (RMM) between 1998 to 2004 in Paraná. It presents an 822 maternal deaths analysis in this period, the calculation of the Specific Maternal Mortality Ratio, the Relative Risk, the frequency and the Odds Ratio for some variables, according to number of gestations. Analyzes also the causes and the prevent way the maternal deaths. The results aimed low TFT (1.8 children by woman) and to RMM elevated (69,7/100.000 been born alive) in Paraná in 2004. A quarter of the 822 maternal deaths (206) was of multigestas (gesta >; 5), the maternal death relative risk was six times higher than for the women with to two gestations, and the profiles sociodemographic and the reproductive one were more unfavorable for that group of women. Incomplete schooling, equal age or above 30 years and less than four prenatal medical consultations presented association with the most greatest number of gestations. The deaths proportion by indirect obstetric causes, hemorrhages and abortion was bigger between the multigestas and around 90% of the deaths of this group was considered avoidable. It concluded that monitoring of the multigestas with advanced age and in social disadvantage, as well as effective actions of family planning, and obstetric service qualified for high risk gestation are measures that can contribute for reduction of the maternal mortality in Paraná

On the use of a reflective architecture to augment Database Management Systems

The Database Management System (DBMS) used to be a commodity software component, with well known standard interfaces and semantics. However, the performance and reliability expectations being placed on DBMSs have increased the demand for a variety add-ons, that augment the functionality of the database in a wide range of deployment scenarios, offering support for features such as clustering, replication, and selfmanagement, among others. The effectiveness of such extensions largely rests on closely matching the actual needs of applications, hence on a wide range of tradeoffs and configuration options out of the scope of traditional client interfaces. A well known software engineering approach to systems with such requirements is reflection. Unfortunately, standard reflective interfaces in DBMSs are very limited (for instance, they often do not support the desired range of atomicity guarantees in a distributed setting). Some of these limitations may be circumvented by implementing reflective features as a wrapper to the DBMS server. Unfortunately, this solutions comes at the expense of a large development effort and significant performance penalty. In this paper we propose a general purpose DBMS reflection architecture and interface, that supports multiple extensions while, at the same time, admitting efficient implementations. We illustrate the usefulness of our proposal with concrete examples, and evaluate its cost and performance under different implementation strategies

GORDA: an open architecture for database replication

Database replication has been a common feature in database management systems (DBMSs) for a long time. In particular, asynchronous or lazy propagation of updates provides a simple yet efficient way of increasing performance and data availability and is widely available across the DBMS product spectrum. High end systems additionally offer sophisticated conflict resolution and data propagation options as well as, synchronous replication based on distributed locking and two-phase commit protocols. This paper presents GORDA architecture and programming interface (GAPI), that enables different replication strategies to be implemented once and deployed in multiple DBMSs. This is achieved by proposing a reflective interface to transaction processing instead of relying on-client interfaces or ad-hoc server extensions. The proposed approach is thus cost-effective, in enabling reuse of replication protocols or components in multiple DBMSs, as well as potentially efficient, as it allows close coupling with DBMS internals.(undefined

A pragmatic protocol for database replication in interconnected clusters

Multi-master update everywhere database replication, as achieved by protocols based on group communication such as DBSM and Postgres-R, addresses both performance and availability. By scaling it to wide area networks, one could save costly bandwidth and avoid large round-trips to a distant master server. Also, by ensuring that updates are safely stored at a remote site within transaction boundaries, disaster recovery is guaranteed. Unfortunately, scaling existing cluster based replication protocols is troublesome. In this paper we present a database replication protocol based on group communication that targets interconnected clusters. In contrast with previous proposals, it uses a separate multicast group for each cluster and thus does not impose any additional requirements on group communication, easing implementation and deployment in a real setting. Nonetheless, the protocol ensures one-copy equivalence while allowing all sites to execute update transactions. Experimental evaluation using the workload of the industry standard TPC-C benchmark confirms the advantages of the approach

Mortalidade infantil nos últimos quinquênios em Porto Velho, Rondônia – Brasil

Objective: To analyze the evolution of child mortality. Methods: A descriptive ecological study was conducted. The database of deaths provided by the Mortality Information System between 2006 and 2010 was used. Only records in which the city of residence and occurrence of deaths corresponded to the city of Porto Velho and whose children were younger than 12 months at the time of death were included in this study. In addition, only deaths from preventable neonatal and post-neonatal causes were analyzed. Results: In the city of Porto Velho, during the period studied, there is a predominance of mothers aged between 20 and 34 years, whose percentages of child deaths varied between 26.0% in 2006 and 29.0% in 2010, with small variations in the remaining years. There was an increasing trend towards premature deaths, except in 2009, when the percentage was 45.0%. Between 2006 and 2007, this percentage remained at 50.0%, increasing to 53% in 2008 and subsequently to 54.0% of deaths among children younger than one year in 2010. Conclusion: The estimate of incidence of child mortality in the period studied remained higher than the value expected by 2015 in Brazil.Objetivo: Analisar a evolução de mortalidade infantil. Método: Estudo ecológico e descritivo. Utilizaram-se os bancos de dados de óbitos fornecidos pelo Sistema de Informações sobre mortalidade, durante o período de 2006 a 2010. Selecionaram-se apenas os registros em que o município de residência e de ocorrência dos óbitos correspondiam ao município de Porto Velho e os que apresentavam idade menor de 12 meses no momento do óbito. Analisaram apenas os óbitos por causas evitáveis neonatal e pós-neonatal. Resultados: No município de Porto Velho, em período estudado há um predomínio de mães com idade entre 20 a 34 anos, cujos percentuais de óbitos infantis variaram entre 26,0% em 2006 a 29,0% em 2010, com oscilações percentuais nos demais anos. Houve uma tendência crescente de óbitos prematuros, exceto no ano de 2009, cujo percentual foi de 45,0%. Entre os anos de 2006 e 2007 esse percentual manteve-se em 50,0%, aumentou para 53% em 2008 e em 2010 representou 54,0% dos óbitos em menores de 1 ano. Conclusão: A estimativa de incidência de mortalidade infantil foi sempre mais elevada, ao longo do período estudado, do que o valor esperado para o Brasil até 2015
