Esta investigación propone las bases de un modelo de interpretación para el fenómeno de la opinión pública a partir de la Teoría de los Campos de Pierre Bourdieu. Este modelo es el punto de partida para el análisis de la trayectoria de los sentidos renovadores que se desprenden de la Iniciativa Yasuní-ITT, propuesta política del gobierno ecuatoriano surgida en 2007 que consiste en dejar el crudo de tres campos petroleros amazónicos bajo tierra, para lo que se planteó que la comunidad internacional entregue al Ecuador una compensación económica. Los sentidos renovadores identificados son 1) una relación no extractivista con la Naturaleza como eje del debate sobre una economía pos petrolera y 2) un nuevo relacionamiento con los pueblos “otros” que reconoce su condición de sujetos políticos. Ambos sentidos se establecen como renovadores por contraposición con el pensamiento de raíces en la Modernidad que sustenta al capitalismo global como sistema mundo. Propongo que este pensamiento, también denominado pensamiento único, se expresa en los sentidos comunes que dominan el campo de la opinión pública y que son su capital en disputa. Así, el campo de la opinión pública está dinamizado por una lucha de sentidos en que los sentidos renovadores desafían a los sentidos comunes. Observé y describí esta lucha a partir de un seguimiento al discurso de tres agentes sociales fundamentales para el campo de la opinión pública, y definitivos en el caso de la Iniciativa Yasuní-ITT. Estos agentes son el gobierno ecuatoriano, la sociedad civil organizada (Acción Ecológica) y los medios de comunicación masiva (los diarios El Comercio y El Universo). Identifiqué momentos importantes en el devenir de esta iniciativa y analicé el discurso de estos tres agentes sociales en esos momentos. El sustento es el modelo de interpretación trazado para observar el curso y destino de los sentidos renovadores, pero también el funcionamiento de las leyes del “campo” de la opinión pública.

Las Normas Internacionales de Información Financiera NIIF´S se basan en los estándares de registro, valuación presentación y revelación de cada una de las transacciones que afectan los Estados Financieros. Las Normas NIIFS, incluyen el estudio de las Normas Internacionales de Contabilidad (NIC), dentro de estas consta la NIC No. 12, conocida en nuestro país como Impuesto a la Renta, y a nivel internacional como Impuesto a las Ganancias. En el Ecuador por los años 2004, se realiza el informe sobre la observancia de los Códigos y Normas (ROSC), el mismo que fue elaborado por un equipo del Banco Mundial, donde se recomienda dar inicio a la aplicación de normas y para lo cual las empresas públicas y privadas deben prepararse. La NIC 12, Impuesto a las Ganancias, es una norma internacional contable, que apoya específicamente en la interpretación fiscal y armonización contable mediante el reconocimiento de un gasto fiscal, un activo y/o un pasivo por impuestos diferidos. La disposición legal en Ecuador es emitida por la Superintendencia de Compañías, según Registro Oficial 348 del 4 de Septiembre del 2006, donde se manifiesta la obligatoriedad de la adopción NIIF, mientras que el Servicio de Rentas Internas, según Registro Oficial 718 del 6 de Junio del 2012 ( Resol: NAC12-0009), pone en tela de duda la aplicación de la NIC 12, sobre todo en la aplicación de los activos por impuesto diferidos, al no permitir reversar gastos no deducibles hasta Diciembre del 2014, sin embargo el Ejecutivo promulga una ley nominada: “ Ley Orgánica de Incentivos a la Producción y Prevención del Fraude Fiscal” publicada en el Registro Oficial No. 407 del 31 de Diciembre del 2014, misma que rige desde Enero 2015, esta ley reformatoria abarca esencialmente la posibilidad de reconocer impuesto diferidos, lo que permite de alguna manera armonizar la NIC 12.

Sand flies were captured weekly with CDC light traps from December 2003 to November 2005 in three areas of Campo Grande, in the Brazilian state of Mato Grosso do Sul. These areas incorporated two patches of remnant forest and five houses. The blood meals of engorged female sand flies were identified using the avidin-biotin system of immunoenzymatic ELISA capture. Most (327/355) of the females analysed were Lutzomyia longipalpis, of which 66.4% reacted with human blood, 64.8% with that of birds and 8.9% with that of dogs. Females that had taken human blood predominated in the residential areas and two forest patches. The following combinations of blood were also detected for L. longipalpis in some of the samples analysed: bird + human (43.4%), bird + human + dog (6.1%). The combination bird + human + dog + pig was also found for Nyssomyia whitmani. Dogs and pigs appear to have little attractiveness for L. longipalpis. The results obtained demonstrate the eclecticism and high anthropophily of L. longipalpis and raise new questions with regard to the importance of dogs in VL epidemiology and the possible role of man as a source of infection for sand flies.

The seasonal distribution of Lutzomyia longipalpis was studied in two forested and five domiciliary areas of the urban area of Campo Grande; MS, from December 2003 to November 2005. Weekly captures were carried out with CDC light traps positioned on ground and in the canopy inside a residual forest and on the edge (ground) of a woodland and in at least one of the following ecotopes in peridomiciles-a cultivated area, a chicken coop, a pigsty, a kennel, a goat and sheep shelter and an intradomicile. A total of 9519 sand flies were collected, 2666 during the first year and 6853 during the second. L. longipalpis was found throughout the 2-year period, presenting smaller peaks at intervals of 2-3 months and two greater peaks, the first in February and the second in April 2005, soon after periods of heavy rain. Only In one of the woodlands was a significant negative correlation (p < 0.05) between the number of insects and temperature during the first year and the climatic factors (temperature, RHA and rain) was observed. In the domiciliary areas in four domiciles some positive correlations (p < 0.05) occurred in relation to one or more climatic factors; however, the species shows a clear tendency to greater frequency (72%) in the rainy season than in the dry (28%). Thus, we recommend an intensification of the VL control measures applied in Campo Grande, MS, during the rainy season with a view to reducing the risk of the transmission of the disease.

Rodents are responsible for the transmission of more than 60 diseases both to human beings and to domestic animals. The increase in rodent infestation in a given area brings several health problems to the nearby population. Thus, when infestation increases, it is time to take intervention measures. Although many countries have implemented programs aimed at controlling rodent infestation, literature on studies evaluating the effectiveness of intervention measures in urban areas is scarce. Aimed at contributing to the understanding of rodents` population dynamics in urban areas, the objective of this study was to evaluate the effectiveness of the control methods proposed by ""Programa de Vigilancia e Controle de Roedores do Municipio de Sao Paulo`` (Program for Rodents Surveillance and Control in Sao Paulo Municipality), conducted on Jardim Comercial District. As a first step, a survey to assess infestation rates was conducted in 1529 dwellings located in the area studied. After that, a chemical control upon rodents was accomplished in every dwelling infested. One week and six months after completion of control measures, a new evaluation on infestation rates was carried out, in order to verify the effectiveness of the procedures taken and to estimate the re-infestation capacity. Initial infestation rate was 40.0%, and the final infestation rate, 14.4%. Therefore, the effectiveness of the control methods utilized was 63.8%. It can thus be concluded that the control methods applied were quite effective.

Rodents are involved in the transmission to human beings of several diseases, including liptospirosis, which shows high lethality rates in Sao Paulo municipality. Despite this, few studies have assessed the relationship existing between urban environmental conditions and building rodent infestation. With the purpose of clarifying this relationship, an analysis has been conducted in order to quantify the influence of environmental factors upon rodent infestation on a low-income district. Diagnosis of the environmental situation has been performed to evaluate the frequency according to which harborage, food and access sources occur, and a survey on infestation rates in 2175 dwellings in the area studied. The logistic regression analysis showed that among the environmental variables, the one that showed the closest association with rodent infestation was access; followed by harborage, and food. It was concluded that poor socioeconomic and environmental conditions in the area propitiate the occurrence of high rodent infestation rates.

Une langue est comme un être vivant. Elle porte les traces des avis, des sentiments, de la joie et des déceptions de nos ancêtres. En même temps elle reflète les toutes tous derniers modes de vie et la manière de penser et d’agir dans la vie quotidienne. Ce sont sa grammaire, ses mots, ses proverbes et ses citations qui en témoignent. Ses sons soulignés par l’intonation et la prosodie nous laissent presque deviner l’esprit de vitalité, de mélancolie ou d’élégance de la langue et de ces locuteurs. Mais est-ce qu’il est possible de trouver aussi les traces des événements historiques et sociaux dans l’évolution d’une langue? Cette question est centrale dans ce mémoire qui suit l’évolution du français à partir du latin parlé dans l’Antiquité et en comparaison avec celle d’autres langues notamment celle du suédois.

O trabalho consiste em efetuar a análise da rede viária urbana, considerando diferentes períodos de desenvolvimento, correlacionando Indicadores de Configuração da Rede (ICR) e indicadores de ocupação do solo. Efetuou-se um estudo de caso na cidade de Campo Bom, situada na Região Metropolitana de Porto Alegre no estado do Rio Grande do Sul. Calculou-se a relação entre as localizações espaciais de locais de trabalho significativas para a cidade, no caso locais de trabalho industrial, e os eixos viários que apresentam os mais altos valores de ICR, quais sejam, a Conectividade, o Controle Local, a Integração e a Escolha Global. O trabalho foi efetuado em dois períodos de desenvolvimento urbano, sendo que para um deles efetuou-se medidas em redes viárias de dois anos diferentes e no outro um ano somente. os valores dos ICR foram efetuados então em três redes correspondentes aos anos de 1963, 1973 e 1988. Obteve-se então, correlações lineares para os dois períodos analisados entre os quatro indicadores e locais de trabalho com valores próximos a um para o conjunto de eixos principais, confirmando assim a validade da hipótese.
