Surveillance for adverse events after DTwP/Hib vaccination in Brazil: Sensitivity and factors associated with reporting

We estimated the sensitivity, i.e., the proportion of all cases of adverse events following immunization (AEFIs) reported to the Brazilian passive surveillance for adverse events following immunization (PSAEFI) with the diphtheria-tetanus-whole-cell pertussis-Haemophilus influenzae type b (DTwP/Hib) vaccine, as well as investigating factors associated with AEFIs reporting. During 2003-2004, 8303 AEFIs associated with DTwP-Hib were reported; hypotonic-hyporesponsive episodes (HHEs), fever and convulsions being the most common. Cure without sequel was achieved in 98.4% of the cases. The mean sensitivity of the PSAEFI was 22.3% and 31.6%, respectively, for HHE and convulsions, varying widely among states. Reporting rates correlated positively with the Human Development Index and coverage of adequate prenatal care, correlating negatively with infant mortality rates. Quality of life indicators and the degree of organization of health services are associated with greater PSAEFI sensitivity. In addition to consistently describing the principal AEFIs, PSAEFI showed the DTwP/Hib vaccine to be safe and allayed public fears related to its use. (C) 2010 Elsevier Ltd. All rights reserved.

Under-reporting of energy intake is more prevalent in a healthy dietary pattern cluster

The aim of the present study was to determine whether under-reporting rates vary between dietary pattern Clusters. Subjects were sixty-five Brazilian women. During 3 weeks, anthropometric data were collected. total energy expenditure (TEE) was determined by the doubly labelled water method and diet Was Measured. Energy intake (El) and the daily frequency of consumption per 1000 kJ of twenty-two food groups were obtained from a FFQ. These frequencies were entered into a Cluster analysis procedure in order to obtain dietary patterns. Under-reporters were defined Lis those who did not lose more than 1 kg of body weight during the study and presented EI:TEE less than 0.82. Three dietary pattern clusters were identified and named according to their most recurrent food groups: sweet foods (SW). starchy foods (ST) and health), (H). Subjects from the healthy cluster had the lowest mean EI:TEE (SW = 0.86, ST = 0.71 and H = 0.58: P = 0.003) and EI - TEE (SW = -0.49 MJ, ST = - 3.20 MJ and H = -5.09 MJ; P = 0.008). The proportion of Under-reporters was 45.2 (95 % CI 35.5, 55.0) % in the SW Cluster: 58.3 (95 % CI 48.6, 68.0) % in the ST Cluster and 70.0 (95 % CI 61.0, 79) % in the H cluster (P=0.34). Thus, in Brazilian women, Under-reporting of El is not uniformly distributed among, dietary pattern clusters and tends to be more severe among subjects from the healthy cluster. This cluster is more consistent with both dietary guidelines and with what lay individuals usually consider `healthy eating`.

Time-lag in biological responses to landscape changes in a highly dynamic Atlantic forest region

Time-lagged responses of biological variables to landscape modifications are widely recognized, but rarely considered in ecological studies. In order to test for the existence of time-lags in the response of trees, small mammals, birds and frogs to changes in fragment area and connectivity, we studied a fragmented and highly dynamic landscape in the Atlantic forest region. We also investigated the biological correlates associated with differential responses among taxonomic groups. Species richness and abundance for four taxonomic groups were measured in 21 secondary forest fragments during the same period (2000-2002), following a standardized protocol. Data analyses were based on power regressions and model selection procedures. The model inputs included present (2000) and past (1962, 1981) fragment areas and connectivity, as well as observed changes in these parameters. Although past landscape structure was particularly relevant for trees, all taxonomic groups (except small mammals) were affected by landscape dynamics, exhibiting a time-lagged response. Furthermore, fragment area was more important for species groups with lower dispersal capacity, while species with higher dispersal ability had stronger responses to connectivity measures. Although these secondary forest fragments still maintain a large fraction of their original biodiversity, the delay in biological response combined with high rates of deforestation and fast forest regeneration imply in a reduction in the average age of the forest. This also indicates that future species losses are likely, especially those that are more strictly-forest dwellers. Conservation actions should be implemented to reduce species extinction, to maintain old-growth forests and to favour the regeneration process. Our results demonstrate that landscape history can strongly affect the present distribution pattern of species in fragmented landscapes, and should be considered in conservation planning.

A psychophysical and computational analysis of the spatio-temporal mechanisms underlying the flash-lag effect

Several accounts put forth to explain the flash-lag effect (FLE) rely mainly on either spatial or temporal mechanisms. Here we investigated the relationship between these mechanisms by psychophysical and theoretical approaches. In a first experiment we assessed the magnitudes of the FLE and temporal-order judgments performed under identical visual stimulation. The results were interpreted by means of simulations of an artificial neural network, that wits also employed to make predictions concerning the F LE. The model predicted that a spatio-temporal mislocalisation would emerge from two, continuous and abrupt-onset, moving stimuli. Additionally, a straightforward prediction of the model revealed that the magnitude of this mislocalisation should be task-dependent, increasing when the use of the abrupt-onset moving stimulus switches from a temporal marker only to both temporal and spatial markers. Our findings confirmed the model`s predictions and point to an indissoluble interplay between spatial facilitation and processing delays in the FLE.

Manipulation in Newspaper Articles : A Political Discourse Analysis of Lexical Choice and Manipulation in Japanese Newspaper Crisis Reporting in the case of North Korea

This paper analyzes some forms of linguistic manipulation in Japanese in newspapers when reporting on North Korea and its nuclear tests. The focus lies on lexical ambiguity in headlines and journalist’s voices in the body of the articles, that results in manipulation of the minds of the readers. The study is based on a corpus of nine articles from two of Japan’s largest newspapers Yomiuri Online and Asahi Shimbun Digital. The linguistic phenomenon that contribute to create manipulation are divided into Short Term Memory impact or Long Term Memory impact and examples will be discussed under each of the categories.The main results of the study are that headlines in Japanese newspapers do not make use of an ambiguous, double grounded structure. However, the articles are filled with explicit and implied attitudes as well as attributed material from people of a high social status, which suggests that manipulation of the long term memory is a tool used in Japanese media.

Desafios para implementação do global reporting initiative nas empresas sucroenergéticas no Brasil

Desafios para implementação do global reporting initiative nas empresas sucroenergéticas no Brasil A pesquisa pretende avaliar o grau de maturidade necessário para elaboração e publicação de um Relatório de Sustentabilidade Integrado. O setor sucroenergético brasileiro foi escolhido para a pesquisa por aderir ao padrão da Global Reporting Initiative para relatórios de sustentabi-lidade e por ser um setor com exposição nacional e internacional, que vem passando por grandes transformações com entrada de novos players nacionais e internacionais, profissionalização da gestão, alterações de práticas operacionais visando atender exigências ambientais e sociais. Para se entender o grau de maturidade das organizações foi preciso definir seis fundamentos de supor-te à realização de um relatório integrado: processos, estrutura, pessoas, sistemas, políticas e pro-cedimentos e cultura organizacional. A seguir, foram estabelecidos três graus de maturidade – alto, médio e baixo. Assim, para cada um desses fundamentos foi atribuído um grau de maturida-de. Na prática de elaborar relatórios de desempenho as organizações podem estar em diferentes estágios de um processo evolutivo. Elas têm por fim a publicação de um relatório integrando os aspectos econômicos, ambientais e sociais, denominado triple bottom line. Nesse processo evolu-tivo, existem as empresas que reportam seu desempenho econômico financeiro e há as que repor-tam o relatório anual da administração mais completo e que pode conter o relatório de sustentabi-lidade. Os dois estágios requerem a aplicação dos fundamentos descritos acima, mas em graus de complexidades diferentes. Para elaborar e publicar um relatório integrado, o grau de utilização dos fundamentos deverá ser muito maior. Esse grau de maturidade na aplicação dos fundamentos será determinante para o processo de interação com os stakeholders, criar um relatório transpa-rente e que seja também útil às suas interpretações e decisões. A pesquisa detectou que as empre-sas do setor, como o esperado, têm o grau de maturidade alto quando se trata de reportar o de-sempenho econômico-financeiro. Quando se trata dos indicadores ambientais, já se nota uma evolução em relação ao tema; há um esforço maior a ser empreendido quando o assunto é o re-porte dos aspectos sociais. Independentemente do grau de maturidade, a iniciativa das empresas do setor sucroenergético brasileiro (na região Centro-Sul), na evolução dos Relatórios de Susten-tabilidade, deverá reverter em prol do desafio global para o meio ambiente.

Compliance com os requisitos de divulgação do IFRS - International Financial Reporting Standards e sua relação com o erro de previsão dos analistas de mercado

O objetivo deste estudo é fazer uma análise da relação entre o erro de previsão dos analistas de mercado quanto à rentabilidade das empresas listadas na BM&FBOVESPA S.A. (Bovespa) e os requerimentos de divulgação do International Financial Reporting Standards (IFRS). Isto foi feito através da regressão do erro de previsão dos analistas, utilizando a metodologia de dados em painel no ano de implantação do IFRS no Brasil, 2010, e, complementarmente em 2012, para referenciamento desses dados. Partindo desse pressuposto, foi determinado o erro de previsão das empresas listadas na Bovespa através de dados de rentabilidade (índice de lucro por ação/earnings per share) previstos e realizados, disponíveis nas bases de dados I/B/E/S Earnings Consensus Information, providos pela plataforma Thomson ONE Investment Banking e Economática Pro®, respectivamente. Os resultados obtidos indicam uma relação negativa entre o erro de previsão e o cumprimento dos requisitos de divulgação do IFRS, ou seja, quanto maior a qualidade nas informações divulgadas, menor o erro de previsão dos analistas. Portanto, esses resultados sustentam a perspectiva de que o grau de cumprimento das normas contábeis é tão ou mais importante do que as próprias normas. Adicionalmente, foi verificado que quando a empresa listada na BM&FBOVESPA é vinculada a Agência Reguladora, seu erro de previsão não é alterado. Por fim, esses resultados sugerem que é importante que haja o aprimoramento dos mecanismos de auditoria das firmas quanto ao cumprimento dos requerimentos normativos de divulgação, tais como: penalidades pela não observância da norma (enforcement), estruturas de governança corporativa e auditorias interna e externa.

On lag controllers: Design and implementation

Sometimes it is inconvenient or expensive to open the loop of a system to insert lag controllers-for instance, when this system is an open-loop system. A new controller structure where the loop is not opened, and that allows the design of lag controllers as in the case where one can open the loop, is presented. This result can be used by educators in undergraduate courses that deal with classic control system theory, because it allows a better comprehension of the concept of lag compensation and provides a new method for its design and implementation. An example illustrates the application of the proposed method.

Giving up reporting the aggressor: reports of female victims of domestic violence

The goal of this study is to describe the experience of female victims of domestic violence, who forfeited the lawsuits against their aggressors. The interviews were oriented by the question: What was your experience of forfeiting the denunciation of your aggressor? Three themes emerged from the convergence of the testimonies: time passed from the aggression to the denunciation and then to the forfeiting; the partner, the family, the women's precinct; reflecting about the experience, which described the studied phenomenon. The women expressed ambiguous feelings for their aggressor: affection, anger, humiliation and fear. They recognize that they are dominated and humiliated, but notions of justice and equality between spouses do not appear in the testimonies. Forfeiting can be understood in the context of the reproduction of the traditional family structure, conditioned to economic and social factors. Results highlight implications about the role of the Women's Precinct and the healthcare institutions in the care for women who were victims of domestic violence.

DIRECT EXPRESSIONS FOR OGATA LEAD-LAG DESIGN METHOD USING ROOT LOCUS

Direct expressions for the design of a lead-lag continuous compensator using the root locus method and the procedure described in the 1970 and 1990 books by Ogata are presented. These results are useful in the Ogata design method because they avoid the geometrical determination of poles and zeros, making it easier to create a computer-based design.
