OBJECTIVE: HIV transmission has been associated with offering a child food prechewed by an HIV-infected caregiver. We assessed awareness of prechewing and oral prewarming of food by an adult before offering it to a child among HIV-infected pregnant women and clinical investigators in 3 Latin American countries. METHODS: HIV-infected pregnant women at 12 sites (Eunice Kennedy Shriver National Institute of Child Health and Human Development International Site Development Initiative Perinatal Longitudinal Study in Latin American Countries, a prospective cohort trial) in Argentina, Brazil, and Peru were administered a screening survey about prechewing/prewarming of infant foods and cautioned against these feeding practices. Survey responses were analyzed, overall, and stratified according to country. RESULTS: Of the 401 HIV-infected pregnant women interviewed, 34% had heard about prechewing (50% from Argentina, 32% from Brazil, and 36% from Peru), 23% knew someone who prechewed food for infants, and 4% had prechewed food in the past. Seventeen percent had heard about oral prewarming of food, 13% knew someone who prewarmed food for infants, and 3% had prewarmed food for an infant in the past. Women who reported knowing someone who prechewed were more likely to also know someone who prewarmed food (P < .0001). Few site investigators anticipated that their patients would be aware of these practices. CONCLUSIONS: Prechewing food, a potential risk factor for HIV transmission, and orally prewarming food, which has not been associated with HIV transmission but might expose a child to blood from an HIV-infected adult, are not uncommon practices in Latin America. Both practices should be further investigated. Site investigator responses underscore that health care providers could be missing information about cultural practices that patients may not report unless specifically asked.

Objective: This study aimed to assess the relative validity of a food frequency questionnaire.(FFQ), previously validated to measure usual intakes in adults, for measuring dietary intakes in children 5 to 10 y of age. Methods: Dietary intakes were measured using an FFQ and a 3-d dietary record. Healthy children, 5 to 10 y old (n = 151), were recruited from public schools and asked to answer the questions in the FFQ and to provide non-consecutive 3-d dietary records based on reported estimated portion sizes. Paired sample t tests and Pearson`s correlation coefficients were conducted to determine whether the two instruments reported similar values for energy and nutrients. The agreement of quartile categorization between the two instruments was also examined. Results: Estimated energy and nutrient intakes derived from the FFQ were significantly higher than those derived from 3-d dietary records. As expected, Pearson`s correlations increased after adjusting for residual measurement error, presumably due to exclusion of the high within-person variability in intake of these nutrients. Moderate to high (r > 0.50) correlation coefficients were verified for some nutrients such as calcium, folate, vitamin 132, vitamin A, and vitamin C. Conclusion: This FFQ, originally developed for use in adults, appears to overestimate usual energy and nutrient intakes in children 5 to 10 y of age. Further work is necessary to conduct a calibration study to establish adequate portion sizes before instrument adoption in this population. (c) 2008 Elsevier Inc. All rights reserved.

According to the producers, CHROMagar (TM) Listeria medium comes to facilitate the detection, differentiating Listeria monocytogenes from the other species, directly on the isolation process, allowing final results in 72 h, while the traditional method takes up to 10 days. A total of 120 food samples of sliced cooked ham, ground beef and frankfurters was analyzed. From 151 colonies presenting typical L. monocytogenes characteristics on CHROMagar (TM) Listeria (bluish, surrounded by a white halo), only 95 (62.9%) were confirmed as L. monocytogenes. The medium was highly sensitive to detect L. monocytogenes in ground beef and frankfurter, but not in sliced ham. (c) 2007 Elsevier Ltd. All rights reserved.

Experimental animal studies have shown that nicotine exposure during gestation alters the expression of fetal hypothalamic neuropeptides involved in the control of appetite. We aimed to determine whether the exposure to maternal smoking during gestation in humans is associated with an altered feeding behavior of the adult offspring. A longitudinal prospective cohort study was conducted including all births from Ribeirao Preto (Sao Paulo, Brazil) between 1978 and 1979. At 24 years of age, a representative random sample was re-evaluated and divided into groups exposed (n = 424) or not (n = 1586) to maternal smoking during gestation. Feeding behavior was analyzed using a food frequency questionnaire. Covariance analysis was used for continuous data and the chi(2) test for categorical data. Results were adjusted for birth weight ratio, body mass index, gender, physical activity and smoking, as well as maternal and subjects` schooling. Individuals exposed to maternal smoking during gestation ate more carbohydrates than proteins (as per the carbohydrate-to-protein ratio) than non-exposed individuals. There were no differences in the consumption of the macronutrients themselves. We propose that this adverse fetal life event programs the individual`s physiology and metabolism persistently, leading to an altered feeding behavior that could contribute to the development of chronic diseases in the long term.

Background: Mice allergic to ovalbumin (OVA) avoid drinking a solution containing this antigen. This was interpreted as related to IgE-dependent mast cell degranulation and sensory C fiber activation. Methods: We employed pharmacological manipulation to further investigate the mediators involved in immune-induced food aversion. Results: While nonimmunized rats preferred a sweetened OVA solution, immunized rats avoided it. We also employed a paradigm in which rats are conditioned to drink water for two 10-min sessions a day. Tolerant rats presented lower IgE titers, and this manipulation abrogated food aversion. Dexamethasone (1.0 mg/kg) prevented the aversion of OVA-immunized rats to the antigen-containing solution. Combined blockade of H(1) and 5-hydroxytryptamine (5-HT)(2) receptors by promethazine (3.0 mg/kg) plus methysergide (5.0 mg/kg) was unable to alter food aversion. Blockade of 5-HT(3) receptors by ondansetron (1.0 mg/kg) caused a twofold increase in the ingestion of the sweetened OVA solution by immunized rats, suggesting the involvement of 5-HT(3) receptors in food aversion. Finally, we showed that dexamethasone or promethazine plus methysergide, but not ondansetron, effectively prevented the IgE-dependent mast-cell-degranulation-induced increase in vascular permeability in rats. Conclusion: We suggest that regardless of whether or not they cause edema, IgE-mediated mast cell degranulation and consequent 5-HT(3) signaling are involved in the process that triggers avoidance to the source of the allergen in allergic rats.

Reduction in leaf area in corn plants during reproduction changes physiological metabolism and consequently the accumulation of dry matter in grains. The aim of this work was to study changes in agronomic characteristics caused by defoliation in corn during the reproduction phase. The experiment was carried out in Uberlândia, Minas Gerais state, in the agricultural year 2007/2008. The experiment was arranged in a randomized block design, consisting of seven treatments: control without defoliation, removal of two apical leaves, removal of four apical leaves, removal of all leaves above spike, removal of four intermediate leaves, removal of all leaves below spike, and removal of all plant leaves, with five repetitions. The genotype used for the evaluations was hybrid NB 7376. Defoliation was carried out when plants were at the growth stage R2. The variables assessed were: yield, density of spikes and corncobs, root resistance and stem integrity. When all leaves above the spike were removed, grain yield was reduced by 20%. Corncob density, stem integrity and root resistance to uprooting were also affected. Spike density was only affected when all plant leaves were removed. The leaf area remaining physiologically active above the spike was found to be most efficient in terms of grain yield.

This paper analyses the commercial and socio-demographic antecedents of the importance of price in buyers' decisions. The study uses ordinal regression in order to analyze the data obtained from a random sample of consumers of frequently purchased products; these consumers were surveyed in different stores. The results demonstrate that shopping enjoyment and brand loyalty have an influence over the importance of price. However, responsibility for shopping (purchase frequency) does not show a significant relationship. Furthermore, some interesting socio-demographic characteristics were found in the context of the study that can be analyzed in future research.

In sport there is a great need to obtain as much information as possible about the factors which affect the dynamics of play. This study uses sequential analysis and temporal patterns (T-patterns)to examine the evolution of defence (against an equal number of attackers)as used by the Spanish handball team at the Beijing 2008 Olympic Games. The aim is to help handball coaches (during their training and gathering of professional experience)to understand the importance of the structure of defensive systems. This can be achieved through observational processes that reveal the evolution and adaptation of these defensive systems according to different variables: the match score, the response of the opposing team and progress through the tournament.

RESUMO: Com o actual quadro de descentralização de atribuições e competências da administração central para as autarquias locais, na área da educação, os municípios passam a investir cada vez mais na acção educativa ao liderarem e planearem políticas educativas locais mais ou menos explícitas, e, nalguns casos, tentando superar carências que o sistema educativo apresenta. Esta pesquisa tem como problemática compreender o papel do Estado na (re)configuração das políticas de educação, quando a tendência para a mudança, de um Estado-educador para um Estado-regulador, tem por pressuposto o discurso neoliberal de que com ‗menos‘ Estado mas maior accountability se obtêm melhores resultados. Este processo origina uma redefinição no papel e funções do Estado no plano social e económico, provocando constrangimentos e conflitos de poder no que respeita ao seu controlo político, com a redistribuição de poderes entre o Estado e a comunidade, entre o central e o local. É neste contexto de mudança que a presente investigação, que se situa no âmbito da análise das políticas educativas, procura averiguar como e com que meios as autarquias locais concretizam as suas competências na área da educação. A estratégia de investigação concentra-se em uma metodologia qualitativa, com a utilização de um estudo exploratório, em três municípios da Região de Lisboa e Vale do Tejo. As actuais políticas educativas derivam da nova visão na gestão da coisa pública – res publica –, como resultado da nova concepção para o próprio Estado, e dos processos de elaboração das decisões político-educativas. Nesta perspectiva, a descentralização passa a ser um instrumento do poder local que favorece o aumento da autoridade democrática dos actores. Todavia, a governação – governance – supõe uma dinâmica de negociação, até mesmo de regulação entre o Estado, a região, o local, a escola e o mercado, feita para atender à construção do interesse geral, que já não é totalmente definido pelo Estado, mas construído em conjunto com as diversas forças políticas, económicas, educativas e sociais. O estudo permitiu evidenciar que a descentralização é posta em causa pelo Estado central, quando este ‗recentraliza‘ decisões e condiciona o poder local, com o fecho da maioria das escolas do primeiro ciclo e a verticalização dos agrupamentos escolares. Por sua vez, algumas políticas educativas como a ‗Escola a Tempo Inteiro‘ fomentam a desregulação dos vínculos laborais, forçando os municípios a aumentar os seus meios técnicos e humanos e a construírem novas infra-estruturas educativas. As políticas educativas passaram a ser concebidas segundo uma matriz híbrida, que visam a municipalização da educação – do pré-escolar e de todo o ensino básico –, por um lado; e fomentam a situação de ‗quase-mercado‘ com a privatização de sectores e o financiamento de várias instituições – que fornecem serviços na área da educação –, por outro lado. ABSTRACT: With the current framework of decentralization of functions and powers from central government to local authorities, in education, the municipalities are investing each more in educational work in leading educational policies and planning places more or less explicit and in some cases, trying to overcome shortcomings that education system. This research aims to understand the role of the state in the (re) configuration of education policies, when the tendency for the change in a State-Educator for a State-regulator, is the assumption that neo-liberal speech that with 'less' State but with more accountability we achieve better results. This process leads to a redefinition of the role and State functions in socio-economic constraints, resulting in power struggles with regard to its political control, with the redistribution of powers between the state and community, between the central and local. It is in this changing context that the present investigation, which lies in the examination of education policy addresses the question how and by what means the local, materialized their skills in education. The strategy focuses on a qualitative methodology, with the use of an exploratory study in three municipalities of Lisbon and Tagus Valley. The current education policies come from the new vision in the management of public affairs - res publica - as a result of the new design for the State itself, and the process of preparation of educational policy decisions. In this perspective, decentralization becomes an instrument of local government that favours the increase of democratic authority of the actors. However, the governance assumes a dynamic negotiation, even in regulation between the State, region, local authorities, school and market, made to suit the construction of general interest, which is not anymore fully defined by the State, but constructed together with the various political, economic, educational and social forces. The study indicates that decentralization is undermined by the central government when it ‗re-centralize‘ decisions and the local conditions, with the closure of most primary schools and with vertical groupings of schools. In turn, some educational policies such as 'Full Time School' forced the municipalities to increase their technical and human resources, to build new educational infrastructure. The educative policies began to be designed according to a hybrid matrix, which aims the decentralization of education - from pre-school and all the primary school - on one hand, and promote the situation of 'quasi-market' with privatization of sectors and the financing of several institutions - that provide services in education -, on the other hand. RÉSUMÉ: Avec le cadre actuel de décentralisation des fonctions et pouvoirs du gouvernement central aux autorités locales, dans l'éducation, les municipalités investissent de plus en plus dans le travail éducatif dans la conduite des politiques éducatives en mener et en faisant la planification des lieux plus ou moins explicites et, dans certains cas, essayer de remédier aux lacunes que présente l'éducation. Donc, nous voulons avec cette recherche comprendre le rôle de l'Etat dans la (re) configuration des politiques d'éducation, alors que la tendance au changement d‘un État-éducateur pour un État-régulateur, a comme l'hypothèse le discours néo-libéral de que avec «moins» État, mais plus d‘accountability on a des meilleurs résultats. Ce processus conduit à une redéfinition du rôle et des fonctions de l'Etat au plan social et économique, en donnant lieu à des luttes de pouvoir à l'égard de son contrôle politique, avec la redistribution des compétences entre l'État et la collectivité, entre les niveaux central et local. C‘est dans ce contexte changeant que la présente enquête, qui réside dans l‘examen de la politique de l‘éducation aborde la question de savoir comment et par quels moyens le local matérialisé leurs compétences dans l‘éducation. La stratégie est axée sur une méthodologie qualitative, avec l'utilisation d'une étude exploratoire dans trois municipalités de Lisbonne et Vallée du Tage. Les politiques actuelles d'éducation sont tirées de la nouvelle vision dans la gestion des affaires publiques - res publica – à la suite de la nouvelle conception de l'État lui-même, et le processus de préparation des décisions politique-éducatives. Dans cette perspective, la décentralisation devient un instrument de gouvernement local qui favorise l'augmentation de l'autorité démocratique des acteurs. Toutefois, la gouvernance assume une dynamique de négociation, même en matière de réglementation entre l'État, la région, le local, l'école et le marché, faite pour répondre à la construction d'intérêt général, qui n'est pas plus entièrement défini par l'Etat, mais construit en ensemble avec les divers forces politiques, économiques, éducatives et sociales. L‘étude indique que la décentralisation est minée par le gouvernement central quand il ‗re-centralise‘ les décisions et les conditions locales, avec la fermeture de la plupart des écoles du premier cycle et avec des groupements verticaux d‘écoles. À leur tour, certaines politiques éducatives telles que ‗l'école à temps plein‘ forcé les municipalités à accroître leurs ressources techniques et humaines, de construire de nouvelles infrastructures éducatives. Les politiques éducatives ont commencé à être conçues selon une matrice hybride, qui vise à la municipalisation de l'éducation - de l'école maternelle et de toute l'école basique - d'une part ; et de promouvoir la situation de «quasi-marché» avec la privatisation de secteurs et le financement de plusieurs institutions - qui offrent des services dans l'éducation -, d‘autre part.

O presente estudo trata dos fatores motivacionais, cuja temática vem sendo discutida intensamente, nas últimas décadas, por pesquisadores na área de Educação e Psicologia, em virtude do aumento dos problemas relacionados à falta de motivação que influencia, negativamente, o processo de ensino e aprendizagem. O objetivo deste estudo foi analisar os fatores motivacionais que estão presentes no processo de aprendizagem dos alunos do 5º ano do ensino fundamental de duas Escolas Públicas em Sergipe, sendo uma da rede estadual de ensino da capital sergipana(Aracaju); e outra da rede municipal de uma das cidades do interior sergipano (Boquim). Os sujeitos da pesquisa foram 32 alunos. O procedimento metodológico utilizado foi levantamento bibliográfico, coleta de dados através da aplicação de uma escala de motivação, entrevistas com os alunos e documentos (atas do rendimento escolar do ano de 2008). Como resultados, a pesquisa revelou maior pontuação na motivação intrínseca (MI) do que na motivação extrínseca (ME). Todavia, houve uma acentuada semelhança nos resultados de medidas centrais encontradas, e a relação com os resultados de aprendizagem foi pouco significativa.

RESUMO: Diversos estudos realizados na área educativa têm demonstrado a importância de escolaridade para a melhoria da qualidade de vida das pessoas. Apesar disso, o alto índice de repetência e evasão escolar está presente em diversas escolas do país. Para tanto, este trabalho tem como tema central o dilema da repetência e da evasão em escolas rurais de um município sergipano. Assim, o trabalho desenvolve uma análise sobre os altos índices de evasão e de repetência em escolas rurais, apoiada numa revisão de literatura que discute essa temática. Participaram dessa pesquisa 10 alunos evadidos da 1° a 4° séries do Ensino Fundamental, no qual, o processo de coleta de dados foi a entrevista semi-estruturada, onde os questionamentos foram formulados através de um roteiro prévio de cinco questões. Através dessas questões, procurou-se discutir e refletir as causas da agravante repetência e evasão com alunos rurais, além da possibilidade de seus retornos às escolas vencendo os obstáculos que a educação local impõe. Trabalhamos também a história de vida de cada entrevistado. Por fim, buscou-se oferecer subsídios para a compreensão das condições em que educação rural se encontra. ABSTRACT: Several studies in the field of education have demonstrated the importance of education to improve the quality of life. Nevertheless, the high rate of grade repetition and dropping out is present in several schools in the country. Therefore, this work is focused on the dilemma of grade repetition and dropping out in rural schools in the municipality of Sergipe. Thus, this paper provides an analysis of the high grade repetition and dropout rates in rural schools, including a literature review which discusses this theme. Ten students who stopped their education after elementary school grades 1st to 4th participated in this study, where the process of data collection was a semi-structured interview with questions formulated from a script of the previous five questions. Through these questions, we sought to discuss and reflect upon the causes of aggravated student grade repetition and dropping out in rural areas, beyond the possibility of their return to the schools by overcoming the obstacles that the local education imposes. We worked also their life story. Finally, we attempted to provide background information on the conditions which constitute a rural education.

RESUMO: O presente estudo pretende analisar a imagem percebida de Lisboa como destino turístico por parte do mercado finlandês, considerando as seguintes perguntas de partida: a) quais os elementos que caracterizam a imagem percebida de Lisboa como destino turístico por parte dos turistas finlandeses; b) quais os factores com maior predominância na imagem percebida e c) qual o perfil do turista finlandês que visita Lisboa. Para atingir os objectivos deste estudo, foi realizado um inquérito por questionário a turistas finlandeses em Lisboa, de forma autoministrada, nos meses de Maio, Junho, Setembro e Outubro de 2008, no último dia da sua estada. Para além de questões que visaram compreender a imagem percebida de Lisboa como destino turístico, por parte dos inquiridos, o questionário incluiu perguntas sobre as suas características sócio-demográficas. Os resultados confirmaram as três componentes da imagem propostas no modelo de Echtner e Ritchie: psicológica-funcional, atributos-holística e comum-única. Os mesmos permitem também concluir que os inquiridos valorizam principalmente as características históricas e estéticas da cidade, como também o bom clima e a simpatia da população local. Por sua vez, os aspectos relativos à programação, eventos, diversão nocturna, interacção com a população local e preços, são os factores menos associados à cidade pelos inquiridos. As qualidades e as características únicas de Lisboa foram destacadas, tendo-se também verificado um elevado grau de satisfação com a visita à cidade e um vasto leque de sugestões dos inquiridos para melhorar Lisboa como destino turístico. ABSTRACT: This study aims to analyze the perceived image of Lisbon as a tourist destination by the Finnish market, considering the following questions: a) what are the elements that characterize the perceived image of Lisbon as a tourist destination by Finnish tourists b ) what features/attributes are most predominant in the perceived image c) what is the sociodemographic profile of the Finnish tourist who visits Lisbon. Data was collected in May, June September and October 2008. The questions were used seeking to identify the image of Lisbon of the respondents as a tourist destination, as well as the socio-demographic characteristics of the tourists. The results identified the three components of the image model proposed by Ritchie and Echtner: psychological-functional, attributes-holistic and commonunique. The results also allowed to conclude that respondents identify and value particularly historical and aesthetic characteristics, as well as the good weather and the friendliness of the local people whereas factors of the city such as the events, the nightlife, the interaction with the local population and the price level, didn’t particularly convinced the respondents. The qualities and the unique characteristics of Lisbon were highlighted, having also noticed a high degree of satisfaction on the visit to the city and a wide range of suggestions obtained from respondents to improve Lisbon as a tourist destination. TIIVISTELMÄ: Perehdyin tutkielmassani suomalaisten kokemusperäiseen mielikuvaan Lissabonista matkakohteena. Tutkimuksen tavoitteena oli selvittää, millaisia kokemuksia ja mielikuvia suomalaisilla matkailijoilla on Lissabonista matkakohteena. Tutkimus pyrki vastaamaan kolmeen kysymykseen: a) mitkä tekijät luonnehtivat suomalaisten matkailijoiden kokemusperäistä mielikuvaa Lissabonista matkakohteena, b) mitkä ominaisuudet hallitsevat kyseistä mielikuvaa sekä c) mihin sukupuoli-, ikä-, koulutus- ja yhteiskuntaluokkaan Lissabonissa vierailevat suomalaiset matkailijat kuuluivat. Tiedot kerättiin touko-, kesä-, syys- ja lokakuussa 2008. Kyselyssä keskityttiin pääosin matkailijoiden kokemuksiin ja mielikuviin Lissabonista sekä matkan ominaisuuksiin ja matkailijoiden matkakohdetta koskeviin tietoihin. Lisäksi matkailijoita pyydettiin kirjoittamaan, miten Lissabonin asemaa matkakohteena voitaisiin parantaa. Alkuperäisen olettamuksen mukaan tulokset osoittivat Echtnerin ja Richien ehdottaman mallin mukaisesti mielikuvien muodostuvan kolmesta osatekijästä: toiminnallinen-psykologinen, attribuutti-kokonaisvaltainen ja yleinenainutlaatuinen. Tulokset osoittivat vastaajien yhtyvän mielikuvissaan ensisijaisesti kaupungin toiminnallisiin osatekijöihin. Sen sijaan kaupungin tapahtumiin ja yöelämään tai vuorovaikutukseen paikallisten kanssa taikka hintatasoon liittyviä ominaisuuksia ei koettu erityisen merkittäviksi. Vastauksista tulivat selvästi esille Lissabonin vetovoimatekijät ja ainutlaatuiset ominaisuudet matkakohteena. Lisäksi vastaukset osoittivat matkailijoiden olleen suurimmaksi osaksi erittäin tyytyväisiä vierailuunsa kaupungissa. Vastauksiin sisältyi myös useita ehdotuksia Lissabonin aseman parantamiseksi matkailukohteena.

Objetiva-se neste artigo responder a seguinte questão: quais foram as propostas e as mudanças nos mecanismos de regulação do mercado postal brasileiro e na estrutura organizacional da Empresa Brasileira de Correios e Telégrafos (ECT) entre 1994 e 2011? Verifica-se que, entre 1994 e 2002, a proposta do governo federal, apresentada em 1999 por meio da "Nova Lei postal", previa a criação do Sistema Nacional de Correios, liberalizando o mercado postal, criando um órgão regulador e transformando a ECT em uma empresa de economia mista. Apesar da não aprovação do projeto de lei, algumas de suas propostas foram retomadas, a partir de 2008, pelos diagnósticos e propostas do governo Lula para reestruturar o setor postal brasileiro. As propostas subsidiaram a aprovação da Lei nº 12.490 de 2011, que internacionalizou a ECT, ampliou os segmentos de mercado da empresa e a reestruturou com base no modelo das sociedades anônimas.

O presente trabalho tem como objectivo analisar a evolução da divulgação voluntária de informação das empresas cotadas na Euronext Lisboa, no triénio 2006-2008. O estudo foi desenvolvido através da análise aos relatórios e contas anuais publicados nos anos de 2006, 2007 e 2008 e aos relatórios de sustentabilidade dos mesmos anos, quando disponibilizados, abrangendo 53 empresas. Os dados foram analisados e tratados estatisticamente pela análise univariada, bivariada e multivariada. Dos resultados obtidos, concluiu-se que a divulgação voluntária de informação por parte das empresas cotadas na Euronext Lisboa é ainda reduzida nas áreas dos desempenhos ambiental e social, apesar de ter tido uma evolução positiva nos três anos estudados. Dos 79 indicadores, apenas 30 são divulgados por estas empresas, revelando assim uma reduzida adesão à divulgação voluntária de informação segundo a estrutura da GRI. Quanto aos actores determinantes, apurou-se que a dimensão contribui para a divulgação de informação e que, pelo contrário, a rendibilidade não é um factor influenciador.
