Contexte : La petite enfance constitue une période importante dans l’acquisition de saines habitudes alimentaires. Par leurs connaissances, attitudes, croyances, pratiques et perceptions en alimentation et nutrition, plusieurs intervenants influencent les jeunes enfants : parents, responsables de l’alimentation et éducatrices en services de garde. Objectifs : Cette étude décrit et analyse les perceptions du « bien manger » de 113 responsables de l’alimentation, de 302 éducatrices et de 709 parents d’enfants âgés de 2 à 5 ans en services de garde au Québec. Méthodologie : Ce mémoire porte sur une question ouverte, répétée dans trois questionnaires autoadministrés de la recherche Offres et pratiques alimentaires revues dans les services de garde au Québec. Les réponses ont été recueillies de 2009 à 2010 et analysées au moyen d’une grille de codification construite de manières déductive et inductive. Résultats : L’analyse des données recueillies montre la récurrence des thèmes de la variété, l’équilibre, la modération, des légumes et fruits, mais aussi l’émergence du plaisir, de la santé, du GAC, des qualités organoleptiques, des pratiques coercitives et de la commensalité. Cette recherche dévoile que la variété, la santé et l’équilibre sont communs aux trois catégories d’intervenants, alors que le GAC, le plaisir, la saine alimentation et les qualités organoleptiques figurent plutôt dans les perceptions d’intervenants spécifiques. Conclusion : Ce portrait illustre la compréhension du « bien manger » qu’ont des intervenants jouant un rôle important dans le développement d’enfants âgés de 2 à 5 ans. En outre, il permet d’éclairer les acteurs développant messages, interventions et politiques de santé publique faisant la promotion de la saine alimentation et favorisant la mise en place d’environnements appuyant l’adoption de saines habitudes alimentaires dans les services de garde du Québec ainsi que dans les ménages.

La Explotación Comercial sexual de los niños, niñas y adolescentes – ESCNNA ha ocasionado graves repercusiones en la sociedad, sometiendo a los menores a situaciones que atentan contra su integridad física y psicológica. Por ello, en el marco internacional y nacional se han adelantado diferentes iniciativas para erradicar dicho fenómeno. La Cooperación Internacional para el desarrollo- CI ha sido una valiosa herramienta en el tratamiento del flagelo dados los diferentes canales de ayuda los cuales han contribuido para su intervención. En este sentido, la CI por medio de la Agencia Canadiense para el desarrollo internacional- ACDI y la Fundación Renacer- ECPAT Internacional (End Child Prostitution, Pornography & Trafficking of Children for Sexual Purposes) hicieron posible junto con otros actores el proyecto de CI en Cartagena llamado: “La Muralla soy yo”, el cual buscó la prevención y futura erradicación de la Explotación Sexual de niños y adolescentes en el turismo- ESNAT en la ciudad. En el presente estudio de caso se pretende identificar cómo la CI incide por medio de la ACDI y la red ECPAT Internacional en instituciones locales de Cartagena para la prevención y posible erradicación del problema de la Explotación comercial sexual infantil en niños, niñas y adolescentes, en el contexto del turismo.

El presente trabajo busca analizar los factores que llevaron a que se produjera una importante dinámica migratoria de venezolanos que llegaron a Colombia a invertir o a trabajar en el sector de hidrocarburos. Específicamente se busca encontrar la incidencia de la política de Seguridad Democrática en este fenómeno tomando como periodo de estudio el gobierno de Álvaro Uribe Vélez, es decir, de 2002 a 2010. Se examina la percepción de seguridad en Colombia vista por los venezolanos y por los colombianos y los diferentes factores que contribuyeron al “boom” petrolero en este país. El resultado de las investigaciones de este estudio de caso permite establecer que la Seguridad Democrática si fue un factor incidente en las dinámicas migratorias pero que se articula junto con otros hechos específicos para que se haya dado de la manera que se dio y que en este texto se expone.

En el año 2010 el gobierno de Canadá pública su estrategia de política exterior hacia el Ártico, en la cual manifiesta que esta región es una de las principales prioridades del Gobierno de Stephen Harper en materia de política exterior. Así las cosas, a partir de la perspectiva teórica del realismo neoclásico la investigación se enfoca en analizar por qué la seguridad nacional y la prosperidad económica son los principales intereses de este Gobierno en la zona.

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants that frequently accumulate in soils. There is therefore a requirement to determine their levels in contaminated environments for the purposes of determining impacts on human health. PAHs are a suite of individual chemicals, and there is an ongoing debate as to the most appropriate method for assessing the risk to humans from them. Two methods predominate: the surrogate marker approach and the toxic equivalency factor. The former assumes that all chemicals in a mixture have an equivalent toxicity. The toxic equivalency approach estimates the potency of individual chemicals relative to the usually most toxic Benzo(a)pyrene. The surrogate marker approach is believed to overestimate risk and the toxic equivalency factor to underestimate risk. When analysing the risks from soils, the surrogate marker approach is preferred due to its simplicity, but there are concerns because of the potential diversity of the PAH profile across the range of impacted soils. Using two independent data sets containing soils from 274 sites across a diverse range of locations, statistical analysis was undertaken to determine the differences in the composition of carcinogenic PAH between site locations, for example, rural versus industrial. Following principal components analysis, distinct population differences were not seen between site locations in spite of large differences in the total PAH burden between individual sites. Using all data, highly significant correlations were seen between BaP and other carcinogenic PAH with the majority of r2 values > 0.8. Correlations with the European Food Standards Agency (EFSA) summed groups, that is, EFSA2, EFSA4 and EFSA8 had even higher correlations (r2 > 0.95). We therefore conclude that BaP is a suitable surrogate marker to represent mixtures of PAH in soil during risk assessments.

OBJETIVO: Verificar a ocorrência de Staphylococcus aureus em uma amostra de queijo tipo Minas frescal comercializado na cidade de Poços de Caldas, MG, de modo a obter subsídios que permitam avaliar o risco potencial que este produto pode representar para a saúde da população consumidora. MÉTODOS: Foi investigada a presença e o número de cepas de Staphylococcus aureus em 80 amostras de queijo tipo Minas frescal produzido artesanalmente e comercializado na cidade de Poços de Caldas, MG, Brasil. RESULTADOS: Os resultados obtidos evidenciaram a presença de S. aureus em 40 (50,0%) amostras, cujas contagens revelaram valores médios em torno de 10(5)/g. CONCLUSÕES: Tais achados parecem ser extremamente preocupantes, pois além de se situarem acima do limite máximo de 10³/g estabelecido pelo Ministério da Saúde, estes valores mostraram-se muito próximos dos requeridos para a produção de enterotoxinas em quantidades suficientes para a ocorrência de surtos de intoxicação alimentar estafilocócica.

The Brazilian Network for Continuous Monitoring of GPS - RBMC, since its foundation in December of 1996, has been playing an essential role for the maintenance and user access of the fundamental geodetic frame in the country,. It provides users with a direct link to the Brazilian Geodetic System - SGB. Its role has become more relevant with the increasing use of space navigation technology in the country. Recently, Brazil adopted a new geodetic system, SIRGAS2000, in February 2005, fully compatible with GNSS technology. The paper provides an overview of the recent modernization phases the RBMC network has undergone highlighting its future steps. From its current post-mission mode, the RBMC will evolve into a real-time network, providing real-time data and real-time correction to users. The network enhanced with modern GPS receivers and the addition of atomic clocks will be used to compute WADGPS-type corrections to be transmitted, in real time, to users in Brazil and surrounding areas. It is estimated that users will be able to achieve a horizontal accuracy around 0.5 m (1σ) in static and kinematic positioning and better for dual frequency users. The availability of the WADGPS service will allow users to tie to the new SIRGAS2000 system in a more rapid and transparent way for positioning and navigation applications. It should be emphasized that support to post-mission static positioning will continue to be provided to users interested in higher accuracy levels. In addition to this, a post-mission Precise Point Positioning (PPP) service will be provided based on the one currently provided by the Geodetic Survey Division of NRCan (CSRS-PPP). The modernization of the RBMC is under development based on a cooperation signed at the end of 2004 with the University of New Brunswick, supported by the Canadian International Development Agency and the Brazilian Cooperation Agency. The Geodetic Survey Division of NRCan is also participating in this modernization effort under the same project.
