    Full Text Available En tiempos de recesión, los expertos nos bombardean con cifras relacionadas a la caída del producto interno bruto, al desempleo, entre otras. Dada la situación que presenta hoy en día Venezuela, aunado a la alta inflación y la devaluación de la moneda; el escenario resulta bastante complicado para el consumidor y las empresas proveedoras de bienes y servicios. En este sentido, las PyMES turísticas de Mochima, ubicadas en el Estado Sucre, Venezuela, se presentan como una alternativa para de alguna manera ayudar a disipar ese triste escenario, mediante sus bondades y en combinación con Internet. De allí que el presente artículo aborde desde los aspectos teóricos del turismo hasta las bondades naturales y culturales que ofrece esta zona oriental del país. Se utilizó una metodología de carácter descriptiva y una combinación de estrategia documental y de campo. Se aplicó un muestreo no probabilístico de tipo intencional, seleccionando los elementos con base en criterios de los investigadores. De acuerdo al estudio, se diseñó la página web y se concluyó, que la implementación de la misma ayudaría en gran medida a mejorar los ingresos de la región y darse a conocer tanto a nivel nacional como internacional.

    Full Text Available A chemical and biological preliminary study of the species Vismia cayennensis, collected in the Amazonas state, Venezuela. The antibacterial test of plant bark extract showed significant inhibition in Escherichia coli, Shigella sp and Staphylococcus aureus. In addition, three of the five soluble fractions of different polarity solvents, specifically those of chloroform, acetone and water, maintained moderately active against Shigella sp strain. The hydroalcoholic extract of the plant and the fraction soluble in chloroform, exhibited a significant antiinflammatory effect. Cytotoxicity tests performed by the methods of (3-(4,5-dimetiltiazol-2-yl-5-(3-carboximetoxifenil-2-(4-sulfophenyl-2H-tetrazolium/phenazine methosulfate of (MTS/PMS and sulforhodamine B , revealed that only has water soluble cytotoxic effect. Additionally, a study phytochemical obtained information on the presence of some families of secondary metabolites such as flavonoids, saponins, tannins, polyphenols, anthraquinones, triterpenes and sterols. It can be inferred that the stem bark of the plant V. cayennensis, is a promising source of bioactive secondary metabolites

  5. Metamorfosis del delito de secuestro en el Estado Zulia, Venezuela

    María Alejandra Añez Castillo

    2010-12-01

    Full Text Available El delito de secuestro es un flagelo social que ha experimentado mutaciones en el tiempo. El año 2009 terminó con una cifra sin precedentes en cuanto a los secuestros reportados en Venezuela. Los datos aportados por los organismos oficiales revelan que durante el 2008 hubo 537 secuestros, lo cual representa un aumento de 52% respecto al total del 2007, mientras que en el 2009 la cifra se incrementó en un 62,82%, en relación con el año anterior. Esta investigación tiene como objetivo describir el delito de secuestro en Venezuela, con especial referencia al Estado Zulia, población fronteriza limítrofe con Colombia. Para ello se emplea una metodología de tipo documental- descriptiva. Se revela que no existen esquemas predefinidos que permitan caracterizar este tipo penal, pues, tal y como ha venido sucediendo, es susceptible de llevarse a cabo en cualquier momento y circunstancia, no de modo exclusivo en sujetos de alto estatus socioeconómico, sino con mínimos medios para responder a las exigencias de los plagiarios; de aquí la proliferación de la modalidad del llamado secuestro exprés. El delito de secuestro en Venezuela ha cambiado en forma notable sus patrones: de ser un delito predominantemente político, fronterizo y ejecutado por grupos organizados, ha pasado a ser uno de objetivos sobre todo económicos, urbano, y ejecutado con un fin de lucro por la delincuencia común. En verdad, el Estado Zulia sigue repuntando en la lista de los estados con mayor incidencia de este delito en Venezuela, pero no es el principal, pues ha sido desplazado en posicionamiento por otras urbes del país, encabezadas en la actualidad por la ciudad capital de Caracas.

    2001-01-01

    Full Text Available In response to increasing human population pressure in the Amazonas State of Venezuela greater attention is being given to the "minilivestock" production of the wild rodents paca (Agouti paca, and agouti (Dasyprocta spp as sources of food and income and to reduce the risk of their possible extinction. In preparation for the increased farming of these rodents, this paper reviews published material on their characteristics, distribution, habitat, conservation status, behaviour, reproductive parameters and nutrition. It is concluded that the two rodents paca and agouti, have characteristics that justify greater investment in their domestication and farmed production, although and behavioural issues and reproductive limits need further research.

  8. Geochronology of the basement rocks, Amazonas Territory, Venezuela and the tectonic evolution of the western Guiana Shield

    Energy Technology Data Exchange (ETDEWEB)

    Gaudette, H E; Olszewski, Jr, W J

    1985-01-01

    The Amazonas Territory of Venezuela is a large area of Precambrian basement rocks overlain in some locales by the supracrustal sedimentary and volcanic rocks of the Roraima Formation. The basement rocks are medium to high grade gneisses with both igneous and sedimentary protoliths, plutonic rocks ranging in composition from granite to tonalite, and meta-volcanic rocks. Rb-Sr whole rock, and U-Pb isotopic analyses of zircons indicate a period of medium to high grade metamorphism and intrusion from 1860 to 1760 Ma. Post-tectonic plutonic activity continued to 1550 Ma. The volcanic rocks of the Roraima Formation in Venezuela give an age of 1746 Ma comparable to volcanic rocks of the Roraima Formation in other parts of the Guiana Shield. The ages and distribution of the basement rocks suggest the presence of a tectonic zone, approximately coincident with the Venezuelan-Colombian border, representing an active orogenic boundary between distinct tectonic provinces. The rocks to the northeast of this zone are part of the Trans-Amazonian of the Guiana Shield, while to the southwest and in adjacent Brazil and Colombia, new younger continental crust has been developed and cratonized. We suggest a model of collision and subduction followed by a chan0140n tectonic style to extensional-vertical to produce the basement rocks of the western Guiana Shield in the Amazonas Territory.

    2005-06-01

    Full Text Available Apesar da baixa atividade de usos do solo no Estado, a produção de madeira não é sustentável. Isso é causado, principalmente, pela falta de infra-estrutura dos órgãos responsáveis para monitorar os planos de manejo florestal e de corte raso para agricultura e pecuária. Este estudo apresenta análise de alguns fatores de produção, industrialização e comercialização da indústria madeireira do Estado do Amazonas, visando viabilizar diagnóstico do setor florestal. Essas informações possibilitam o estabelecimento de políticas florestais para a região. Fez-se a definição das zonas de produção, onde os principais municípios produtores de serrados foram Manaus, Itacoatiara, Manacapuru e Parintins; e de compensados e laminados foram Manaus e Itacoatiara. Após essa definição os dados foram coletados diretamente nas indústrias, através de questionários e entrevistas para coletar as seguintes informações: principais espécies consumidas, produtividade das indústrias, origem da matéria-prima, transporte, qualificação de pessoal e treinamento, principais problemas tecnológicos e exportação. Em 2000, a produção estadual foi de 323.400m³ de madeira em toras. Mais de 50 espécies diferentes são usadas nas serrarias, das quais 16 representaram 80% do volume total, sendo as 5 espécies (louro inhamui,angelim pedra,amapá,assacu e maçaranduba contribuíram com 49,34% do consumo total; quanto as indústrias de compensado e laminado estas usaram, 17 espécies onde as 5 principais (muiratinga, sumaúma, copaíba, assacu e amapá representaram 62,71% do consumo total.Também foram coletados dados complementares junto ao IBAMA, SUFRAMA, SEFAZ e IBGE.Despite low land activities, hardwood production is not sustainable.

    Full Text Available Este artigo teve como objetivo analisar o itinerário dos usuários que tiveram acesso a medicamentos via judicial no estado do Amazonas, Brasil. Trata-se de estudo qualitativo, prospectivo, baseado em dados coletados por meio de entrevistas semiestruturadas com usuários que receberam medicamentos via mandado judicial. A judicialização na saúde mostrou-se um fator agregador ao reconhecimento dos direitos e da cidadania pelos usuários que, na sua trajetória de vida, acabaram adquirindo um grande aprendizado sobre formas de enfrentar a falta de acesso aos medicamentos. Conclui-se que a relação entre o sujeito e o Estado permanece desigual, e o direito à saúde se deu na dimensão individual e restritiva, desconsiderando a dimensão coletiva e a concepção de cidadania.

  15. Estados Unidos y Venezuela: Una relación necesaria.

    Directory of Open Access Journals (Sweden)

    Carlos Romero.

    2002-09-01

    Full Text Available The author identifies Hugo Chavez's electoral victory and the implementation of a new type of democracy as two factors that transformed Venezuelan foreign policy, and in particular, the bilateral relationship with the United States. Chavez's international activism, in addition to his Bolivarian policy signaled a shift from "safe partner" to "partner with reservations" in the country's relations with Washington. Although Venezuela considered itself a Latin American showcase in previous years, the text argues that Chavez's populist tendencies, his critical posture towards the promotion of democracy and human rights, and his supposed links with Colombian guerrillas has led to a "wait-and-see" policy characterized by high levels of caution on the part of the United States.

    Full Text Available RESUMEN: Este artículo muestra que las compañías petroleras internacionales han estado haciendo negocios en Venezuela durante más de cuatro quintas partes de casi un siglo de historia de la industria petrolera en este país (1917-2009. Muestra también que lo que ha cambiado para ellas a lo largo del tiempo es la manera de hacer negocios en la industria petrolera venezolana, valga decir, los términos y condiciones de acceso a las actividades de exploración y producción que les ha impuesto el propietario del recurso natural, relacionados particularmente con el reparto de la renta petrolera internacional. El artículo, dividido en cuatro secciones, es una síntesis de la historia del derecho de propiedad del subsuelo, de las compañías petroleras, del Estado y de la renta petrolera internacional en Venezuela desde 1920 hasta el presente. ABSTRACT: This paper shows that in almost a century of history of the Venezuelan oil industry (1917-2009, International Oil Companies (IOCs have been doing business in this country for just more than fourth fifth of this period (74/92 years. It shows too that during that time, what has been changing in this country for the oil companies, IOCs or National Oil Companies (NOCs, is the way of doing business in the upstream of the oil industry: the terms and conditions of the owner of the underground property rights. Terms and conditions mean in this context how much of the oil generated rents in the underground public and national property rights goes to the pockets of the oil companies and government. This paper summarizes the history of the underground property rights, oil companies, the State, and rent in Venezuela from 1920 up to the present.

    The intracratonic Amazonas Basin covers an area close to 500.000km{sup 2} shared between the Amazonas and Para states. The phanerozoic stratigraphic framework is up to 6.000m thick and may be subdivided into two, first order depositional sequences: the Paleozoic sequence, intruded by diabase dikes and sills and the Mesozoic-Cenozoic sequence. Analyzing the stratigraphic framework, the great tectonic influence on the basin development can be appreciated. The mainly NW-SE structural directions of the basement, which mark the boundaries of the geochronological provinces of the Amazonas, are clearly identified along the Tapajos River. The Paleozoic sequence outcrops on the southern border of the Amazonas Basin embraces potential source rocks, reservoirs and seal rocks. They can be subdivided in three, second order sequences, limited by regional unconformities, as: the Ordovician/Devonian, which corresponds to the Pitinga lithostratigraphic formation; the Devonian-Tournaisian, which corresponds to the Maecuru, Erere, Barreirinha and Curiri formations and, the Pensylvanian-Permian that are represented by the Monte Alegre and Itaituba formations. This field trip guide presents these classic lithostratigraphic outcrop units, together with a brief sedimentological description and an analysis of their positioning related to sequence stratigraphical concepts.

    The background notes by the U.S. State Department on Venezuela emphasize the unique economic conditions in this oil-rich nation, and include information on its people, geography, history, government politics, defense and foreign relations. Venezuela, located on the north coast of South America, has 17,791,000 people, growing at a rate of 2.7%. Infant mortality is 2.7/1000, and life expectancy is 70 years. Geography ranges from the scarcely populated highlands between the Orinoco river and Guyana, the Orinoco plains, to the populated Andes mountains and coast. 80% of the population is urban. Literacy is a priority at 88.4%; Technical and university education is increasing; emigration from other countries is common because of relatively good working conditions. Venezuela has a long history of self government, having become independent in 1921. Now the democratic constitutional government is effective in improving both internal and regional development and human rights. The economy is based on oil production and refining, as well as steel and aluminum, all nationalized industries. Self-sufficiency in agriculture is a national goal. Because of the rapid population growth rate, however, per capita income and GNP are stagnating.

    Full Text Available Frente a los retos de los mercados mundializados reaparecen las alianzas o acuerdos interempresariales, que son frecuentemente utilizados por empresas de gran tamaño aun cuando no excluye a las de pequeñas dimensiones. Esta investigación se desarrolló con el propósito de caracterizar las alianzas existentes entre las empresas del estado de Mérida, Venezuela. Para tal efecto, se aplicó un cuestionario a 228 propietarios/gerentes mediante entrevista personal y se contrastó una hipótesis de trabajo. El análisis de los resultados indica baja propensión a establecer alianzas, predominio de las alianzas de naturaleza vertical y en el área de marketing. Prevalecen las none equity alliances y las coaliciones como formas de cooperación. Las formas legales más utilizadas son el outsourcing y la franquicia. Entre los motivos para no aliarse resaltan la falta de confianza y el temor a perder independencia. Finalmente, se encontró una relación moderada entre tamaño relativo de la empresa y la conformación de alianzas.

    Full Text Available Uno de los aspectos más investigados en relación a la “ecología de la carretera” es el atropellamiento de vertebrados silvestres. Se evaluó la distribución espacial y temporal de los atropellos de vertebrados en la carretera Guanare-Guanarito, estado Portuguesa, Venezuela. Desde 2008 hasta el 2010 se realizaron 26 viajes en carro a lo largo de 74km, a 50-60km/h, para un total recorrido de 1 924km. Se encontraron 464 animales muertos: 66 aves (25 especies, 130 mamíferos (15 especies y 268 reptiles (18 especies. La serpiente Leptodeira annulata (n=119, el rabipelado Didelphis marsupialis (n=39 y la baba Caiman crocodilus (n=33 fueron las especies con mayor frecuencia de atropellos. Excluyendo a los animales domésticos, se localizaron 0.2282indviv./km; cifra 28.30% mayor que la reportada en estudios previos en la misma vía. Los cambios en la frecuencia relativa de atropellos de algunas especies con respecto a los reportados hace 20 años, se relacionan con el incremento en el flujo vehicular y por modificaciones en el uso de la tierra. Se identificaron segmentos donde el número de individuos atropellados supera al esperado por azar. Los atropellos pudieran ser la principal causa de mortalidad para especies como el oso melero (Tamandua tetradactyla y el oso hormiguero (Myrmecophaga tridactyla, esta última considerada como una especie vulnerable. Se recomiendan algunas medidas básicas para disminuir la mortalidad de fauna en la carretera.

    Full Text Available Se realizó un estudio seroepidemiologico de amibiasis en una comunidad de bajas condiciones socioeconómicas del Municipio Mara, Estado Zulia, Venezuela. Se estudiaron 283 individuos cuyas edades fluctuaron de 2 a 53 años. Se obtuvieron muestras de sueros, las cuales se examinaron con la prueba de hemaglutinación indirecta de KESSEL et al., según una modificación de MILGRAM et al. Se utilizó antígeno amibiano obtenido de cultivos axénicos de la raza HK9 de E. histolytica. La tasa de seropositividad obtenida fué de 46.6%; la mayoría de los reactores tenía títulos bajos y no presentaba signos de amibiasis. El porcentaje de seropositividad aumentó con la edad. Los resultados sugieren una alta endemicidad de la infección en esta comunidad, ocurriendo la transmisión con mucha mayor frecuencia que la amibiasis invasiva.In the present evaluation, a community of low socioeconomical conditions from Zulia State, Venezuela, was analyzed for the prevalence of antibodies to E. histolytica. Two hundred and eighty three serum samples were collected and examined by the indirect hemagglutination test according to a microtiter modification of the KESSEL and LEWIS method, as used by MILGRAM et al. Antigen prepared from axenically-grown. E. histolytica strain HK9 in Diamond's medium was used. The seropositivity rate obtained was 46.6% and the frequency of positive cases was dependent on age. The antibody profiles obtained suggest a high endemicity for this parasitic infection in the area studied, with a much higher level of transmission than invasive amebiasis.

    Full Text Available Los flebotominos son transmisores de los protozoarios parásitos del genero Leishmania, agentes causales de las leishmaniasis en humanos y otros mamíferos. Mediante modelos nulos, se estudio la estructura de las comunidades flebotominas en focos endémicos de leishmaniasis del estado Falcón, en el nor-occidente de Venezuela, a una escala reducida o local: en el domicilio, peridomicilio y el área silvestre de una zona de vida o en una localidad en particular. La aplicación de los modelos nulos reveló que a escala local las comunidades flebotominas se encuentran agregadas, sugiriendo que las especies coexisten y no compiten. Los estudios de co-ocurrencia con el análisis de estructura gremial y la prueba de la hipótesis de los estados favorecido mostró que los resultados obtenidos no son estadísticamente significativos (p> 0.05, lo que sugiere que las especies flebotominas pertenecen a un mismo gremio en sus preferencias alimentarias, lo que podría deberse a que la hematofagia se trata de un evento heterogéneo, circunstancial y oportunista. Se discuten aspectos sobre los posibles factores, como por ejemplo la transformación y homogenización de los hábitats por el impacto sinantrópico, que pudieran estar determinando el ensamble de los flebotominos en la región falconiana.

A classificação de implantação foi intermediária e insatisfatória. Os resultados mostram aumento no número de municípios com PSF implantado, assim como na cobertura do programa, porém ainda abaixo de 50% da cobertura populacional. Para a dimensão de mudança no modelo assistencial, não foram observados municípios com alto índice de mudança. No indício de impacto houve diminuição no baixo impacto e aumento do alto impacto. O teste estatístico indica que a classificação final não apresentou mudança estatisticamente significante entre um ano e outro, prevalecendo nos municípios do Estado do Amazonas a classificação de implantação insatisfatória. A avaliação do PSF não é algo simples, pois há vários fatores que contribuem para essa problemática.

    Full Text Available A finales de la década de los 70 empieza a manifestarse en Venezuela la crisis del modelo de desarrollo, consistente en una grave situación económica, un gran déficit fiscal, problemas de gobernabilidad, así como elementos de fragmentación social, agudizados en la década de los 90 por los programas de estabilización económica. Por ello, desde 1984 se inicia el proceso de reforma del Estado, cuyos factores predominantes han sido la modernización política, la descentralización, la disminución del Estado social y los requerimientos de una mayor participación de la sociedad civil. Dentro del proceso de descentralización, iniciado en 1989, las gobernaciones promueven políticas de apoyo a las organizaciones de la economía social. El presente trabajo pretende caracterizar la política de la gobernación del estado Zulia dirigida a ese sector durante el periodo 1989-2000, a partir del enfoque de las políticas públicas, con una perspectiva crítico-descriptiva del proceso, por tratarse de una primera aproximación al objeto de estudio. Se construye un enfoque operativo sobre la definición de la economía social, su papel y su significación en los procesos de formulación económica y redefinición del Estado. Se avanza en la caracterización de las organizaciones estudiadas (microempresas, cooperativas y organizaciones no gubernamentales (ONGs, para luego puntualizar las estrategias políticas de los gobiernos. Se concluye, de manera parcial, en la descripción del proceso de formulación de políticas, donde ha predominado la visión utilitaria del sector, sin trascender los procesos organizativos reales que impulsen de manera significativa a estas organizaciones, para que impacten en la economía regional y nacional.

    Full Text Available Las empresas actualmente demandan sistemas de costos que reporten un mayor detalle en la información generada, con el propósito de orientar la aplicación de estrategias que conduzcan a captar y apropiarse de mayores espacios de mercado, sobre todo cuando la competitividad es elevada; por ello, se formuló un sistema de costos basado en actividades, conocido por sus siglas en inglés como abc (Activity-Based Costing, aplicado a los hoteles de turismo de cuatro estrellas de Mérida, en Venezuela, para el control y reducción de costos en los servicios prestados. A partir de una investigación de carácter exploratorio, con un diseño de campo y con apoyo documental, se halló que el sector hotelero encuentra en el abc una oportunidad para afinar controles sobre los altos y variados costos en los que incurre a partir del conocimiento profundo de actividades consumidas, con sus medidas y frecuencia. De esta manera, se obtiene el costo real de los distintos servicios al vincularlos con las actividades desarrolladas para su obtención; finalmente, se sugiere un conjunto de variables que pudieran fungir como generadoras de valor e indicadoras de eficiencia. Se concluye que el abc representa una herramienta de gestión que orienta las decisiones estratégicas y el control de los costos con la consecuente reducción de los mismos para la maximización de beneficios.

    Full Text Available   El conocimiento de temas relacionados con la salud sexual y reproductiva evidencia vacíos en los países latinoamericanos en cuanto a reproducción, especialmente en el medio rural y en personas con menor nivel educativo. Se pretende con esta investigación describir características de la sexualidad en el área rural, primer estudio en Venezuela. Estudio descriptivo, transversal y de campo, con un cuestionario como instrumento, la muestra fue de 128 individuos de la comunidad de Apamates, Cojedes. La edad promedio fue 25,3 años, resultaron solteros 76,5% de los hombres y 43,6% de las mujeres. 96,1% de las personas saben leer y escribir pero únicamente 19,5% tenían bachillerato completo. 35,9% eran obreros y 82,8% recibían sueldo básico. 82% conocen los métodos anticonceptivos. El condón y los anticonceptivos orales son los mayormente usados. Fue baja la prevalencia de ITS. La mayoría tenía entre 0 y 1 hijo. Los hombres por iniciativa propia buscan información sobre sexualidad. El conocimiento sobre sexualidad en ambos géneros es bajo.  Ambos géneros mantienen relaciones sexuales por amor y con fines reproductivos. Desconocen que es el orgasmo. Se concluye que: desconocen aspectos básicos sobre la sexualidad y reproducción; la sexualidad es un tabú; y conocen los anticonceptivos pero no los usa con frecuencia. Para el desarrollo de la sexualidad es indispensable tener educación sexual verdaderamente eficaz.

Em 1992 e 2004, foi aplicado um questionário a 38 extratoras. Sementes das duas espécies de andiroba (Carapa procera D.C. e Carapa guianensis Aubl. foram utilizadas como matéria prima. O processo tradicional é complexo, demora cerca de dois meses e pode ser dividido em três etapas: 1. A coleta, seleção de sementes boas e um primeiro armazenamento (3-15 dias. 2. O preparo da massa pelo cozimento das sementes em água (1-3 horas, um segundo período de armazenamento (até 20 dias e finalizada pela retirada da casca e o amassamento das amêndoas. 3. A extração do óleo (até 30 dias, pelo gotejamento colocando a massa sobre uma superfície inclinada. Óleo extraído na sombra foi considerado de melhor qualidade do que no sol, porém o processo é mais demorado. Uma segunda extração com a prensa ("tipiti", usada na fabricação de farinha, foi raramente empregada. Verificaram-se pequenas variações entre os procedimentos das extratoras, aparentemente com conseqüências na rentabilidade e na qualidade do óleo. Na primeira e segunda etapa da extração participaram membros da família e/ou vizinhos, ao contrário da etapa final, realizada por uma única mulher.

    Full Text Available O objetivo deste trabalho foi avaliar a demanda ambulatorial da Clínica de Odontologia da Universidade do Estado do Amazonas (UEA. Foram entrevistados cem pacientes em tratamento na disciplina de semiologia; por meio de um questionário, foram coletados os dados demográficos e o perfil socioeconômico e por meio de exame clínico foram obtidos o perfil nosológico e o perfil da pressão arterial e das perdas dentais. Os resultados evidenciaram que 52% dos pacientes eram do sexo feminino, com idade predominante entre 20 e 29 anos; 48,3% com o segundo grau incompleto e 60,8% com renda mensal maior que cinco salários mínimos. Quanto à perda dental, os dentes mais acometidos foram os primeiros molares; 29% perderam o primeiro molar superior e 45%, o inferior. O perfil nosológico mais encontrado foi de 31,3% para tratamentos na área de dentística restauradora, seguida de 21% de periodontia e 19% de cirurgia. Apenas um paciente apresentava hipertensão. Concluí-se que a população predominantemente atendida foi de mulheres de classe média baixa, com nível médio de instrução e quadro odontológico precário, evidenciando muitas perdas dentais e necessitando mais de tratamentos reabilitadores do que os preventivos. Com a maior compreensão da realidade dos usuários da clínica odontológica da UEA, será possível melhorar o planejamento do atendimento e das ações para promoção de saúde.The objective of this study was to evaluate the demand of the clinic of Dentistry of UEA.

    Full Text Available La promoción social está vinculada al logro de una nueva visión de escuela proyectada hacia su entorno, en tanto la gerencia participativa se relaciona con la gestión institucional, entendida como la búsqueda de la productividad administrativa y académica, a partir de un nuevo concepto de la acción gerencial que rompe con la dirección vertical y realza la toma de decisiones compartidas; estas premisas están contenidas en el proyecto educativo venezolano. El objetivo de esta investigación fue determinar dimensiones de las variables gerencia participativa y promoción social en docentes y directores de escuelas urbanas del municipio de Trujillo, estado Trujillo, Venezuela. Se hizo una investigación descriptiva, de campo y correlacional basada en la encuesta y se usó el cuestionario como instrumento de recolección de información. Se encuestaron 11 directores y 38 docentes. Como resultados se dan los siguientes: los directores consideran buena y los docentes mala la gestión y la promoción social, con correlación positiva y fuerte entre ambas variables. Se concluye que para los docentes pero no para los directores la gestión es cerrada en las instituciones educativas estudiadas, distante del concepto de gerencia participativa; además, que se deja de lado el importante rol de promotor social que deben exhibir todos los actores involucrados en la educación formal.

O objetivo deste trabalho é apresentar alguns aspectos do processo de deslocamentos transfronteiriços no norte do Brasil, no município de Pacaraima (Estado de Roraima e na fronteira sul da Venezuela, no município de Gran Sabana (Estado Bolívar, e, ao mesmo tempo, apontar as tendências e reflexos nas configurações socioculturais nessas zonas de contato. Nessa fronteira Brasil-Venezuela, podemos afirmar que o trânsito maior é de brasileiros para a Venezuela e para a Guiana, em decorrência das possibilidades de atuarem nas atividades de mineração, no comércio local e no setor de transportes, além das atividades ilegais, como tráfico de mulheres, contrabando de combustível e câmbio ilegal de moeda. Apresenta-se, no entanto, uma nova tendência que é a imigração de estrangeiros de outros países do continente, tais como peruanos e colombianos. Esses migrantes transfronteiriços percorrem os países fronteiriços em itinerários cuja porta de entrada é a Venezuela e a Guiana, mas também o Estado do Amazonas.BORDER zones are zones of cultural lending, borrowing and appropriation, and, therefore, a privileged vantage point for understanding the phenomenon of international migration.

Materiales y métodos: Estudio transversal realizado con una muestra representativa de 478 MEF y 465 niños aguarunas seleccionados por muestreo bietápico probabilístico. Se realizó la toma medidas antropométricas, dosaje de hemoglobina a ambos grupos y finalmente una encuesta de consumo de alimentos a una submuestra de 290 hogares. Resultados: La prevalencia de desnutrición crónica en niños fue de 33,4%. Se encontró asociación estadística entre el distrito de residencia y la desnutrición crónica en niños. La prevalencia de anemia fue de 76,5%. El 89% de las MEF presentaron un IMC ideal, sin embargo, la talla promedio de la mujer aguaruna fue de 148 cm. La prevalencia de anemia en MEF fue de 50,2%. Se listaron más de 100 alimentos locales y foráneos que forman parte de la dieta de las familias aguarunas; sin embargo, sólo se consume diariamente la yuca y plátanos; y con alguna frecuencia semanal el arroz, la carachama, gusano, huevo de gallina y verduras como la chonta y sachaculantro. Conclusiones: La evaluación nutricional indica un déficit nutricional para los niños y la deficiencia de hierro expresada en anemia afecta a la mitad de las MEF y a dos de cada tres niños. Esta situación podría atribuirse, entre otras causas al consumo de una dieta basada principalmente en yuca y plátanos con escasa presencia de alimentos de origen animal.

It features the efficiency of this action of the government from the reality experienced in the context Amazon, which show a framework for various characteristics and natural, cultural and focused on the issue geospatial. This involves understanding the multitude of climates and geographical characteristics, cultural and social constitute major obstacles for the implementation of policies homogeneous, demonstrating that the potential for development of each region has different dynamics, which should influence in the formulation of policies. While electricity is essential for the economic progress of a country, the expansion of its services to society must be viewed with great discretion, in order to prevent the exploitation and consumption exacerbated of natural resources and waste of energy. With this reading, the work he proposes to show the inconsistencies of the program in the state of Amazonas, on presentation of data from the Companhia Energetica do Amazonas (CEAM), showing thus obstacles to the achievement of the goals outlined in the State. Considering the environmental importance that the Amazon represents for Brazil and for the world, emerges is the need for a differentiated look for the region, taking into account their unique reality. It is believed that is the acceptance of their characteristics that we can really promote a development that is sustainable for the Amazon. (author)

    Carlos Enrique Mascareu00F1o Quintana

    2002-01-01

    Full Text Available El presente artículo contiene una aproximación a la dinámica de la relación entre la sociedad civil y el Estado descentralizado en las entidades federales y municipios en Venezuela. La hipótesis central que se maneja es la de que a partir del inicio del proceso de descentralización en 1990, han proliferado grupos civiles organizados alrededor de asuntos públicos como salud, vivienda, educación, vecinales o programas sociales, asociados al desarrollo de competencias ejecutadas por gobernaciones y alcaldías y que la relación que se establece con estas estructuras de gobierno territorial, aún es precaria toda vez que su desempeño depende más de la iniciativa de los gobiernos que de la autonomía del espacio civil. El documento resalta la importancia de esta reciente realidad, enmarcada en las tendencias de complejización de los procesos sociales y de la diferenciación funcional creciente que obliga a la existencia de esferas públicas, más allá del Estado. En esta perspectiva, los procesos de descentralización ofrecen un terreno fértil para ampliar los espacios civiles, siempre y cuando se puedan atenuar los marcados signos movilizadores y clientelares del Estado patrimonialista y dar paso a una creciente institucionalización de la actuación de los grupos civiles en los territorios.

Para alcanzar el objetivo propuesto se revisaron los postulados del Modelo Nacional de Tecnología (MNT (2009 y los aportes teóricos de autores como Gaynor (1999, Peters (2006 y Bosch (2000, en relación con la gestión de tecnología. El estudio fue de tipo descriptivo bajo un diseño de campo, no experimental-transeccional y con una muestra constituida por seis sujetos encargados de gerenciar tecnología en las unidades productivas de la Cervecería Polar y Pepsi de Venezuela. Los resultados obtenidos, mediante el cuestionario utilizado para la recolección de información, permitieron concluir que la gestión de tecnología, en dichas empresas, se desarrolla de manera empírica con una configuración funcional en la cual no existen estándares establecidos en cuanto a su integración con la gestión del conocimiento ni en la necesidad de generar unidades de I+D que tengan foco en la gestión de la tecnología. Sin embargo, el reconocimiento del impacto de la gestión tecnológica en los resultados positivos de la empresa condujo a reconocer mejores prácticas y experiencia a través de las actividades de vigilancia, planeación, habilitación, protección e implantación tecnológica.Palabras Clave: Gestión; tecnología; conocimiento; competitividad. Management of Technology in the Business World Class Beverages Sector in Venezuela Case: San Francisco County - Zulia StateAbstractThe main purpose of this research was to analyze the technology management in world-class companies belonging to the drinking sector at the San Francisco county, Zulia State, Venezuela.

    Stroke, the 5th. cause of death in Venezuela, has been associated to cerebral infarction. However, there is little information concerning lethality factors. 33 atherothrombotic subtype stroke patients, 31 (96%) Latino and 2(4%) white, were admitted into a prospective study to analyze the role of 11 mortality risk factors for those patients. A mortality relative risk (RR) > 1.5 or Mortality RR for patients age 65 and over (RR = 2.95) and 4 year mortality RR for male patients (RR = 2.04) were clinically and statistically significant. History of high blood pressure was protective (RR = 0.62) probably due to good medical control. Cumulative mortality was higher than that of comparable studies, even from the first week of follow-up, reaching 67% at the 4th year.

    Full Text Available Se analizó el crecimiento, la distribución de tallas y la mortalidad de una población de Pinctada imbricata en Guamachito, Península de Araya, Venezuela, entre enero y diciembre de 2000. Los muestreos se realizaron mensualmente sobre transeptos perpendiculares a la línea de la costa con una rastra artesanal, tomando también datos sobre temperatura, oxígeno disuelto y salinidad de la columna de agua. La distribución de tallas fue variable con un predominio de tallas entre 50 y 70 mm, que constituyeron el 75% de la población. La mayor cantidad de juveniles fue observada en marzo, cuando la longitud media en la población fue de 55.8 mm. Los promedios de los pesos húmedo y seco siguieron la misma tendencia, con valores mínimos en junio, julio, septiembre y octubre de 2000. Las relaciones longitud-peso húmedo y longitud-peso seco fueron altamente significativas (P < 0.05. Los parámetros de la ecuación de crecimiento estacionalizada de von Bertalanffy fueron L∞ = 85.15 mm; K = 1.42 año–1, ts = 0.2, y C = 0.20; indicando un crecimiento lento (WP = 0.42 en el periodo de julio a noviembre, asociado con los parámetros ambientales del área con una longevidad estimada en 3 años. La mortalidad total fue de 14.35 año para los individuos pequeños (10–36 mm y 3.45 año, para los individuos grandes (36–84 mm. La alta tasa de crecimiento de P. imbricata muestra ser una ventaja para considerarla como una especie con potencial para actividades de acuicultura en la región. El banco ostrícola presenta buenas condiciones para mantener una explotación pesquera sostenida, tomando en consideración parámetros pesqueros como la captura registrada, el esfuerzo óptimo, la talla mínima de extracción, la mortalidad por pesca y la mortalidad natural.

    Full Text Available El conocimiento de las propiedades físicas de los suelos agrícolas y bióticos proporciona información para el manejo de equipos agrícolas, procesos de compactación y la labranza convencional y conservacionista. A medida que la humedad edáfica aumenta, genera diversos estados del suelo; e.g. una menor interacción entre partículas adyacentes y un comportamiento que se aproxima al del líquido. El inicio de la sensibilidad de compactación, parece ser el límite plástico del suelo bajo una bien definida energía de compactación. El objetivo general, de este estudio fue caracterizar sistemáticamente, con las implicaciones de ingeniería posibles, los suelos agrícolas de sabana del Estado Monagas de Venezuela. Los objetivos específicos consistieron en determinar: a- los límites de Atterberg; y b- el índice de plasticidad y friabilidad. Para ello se utilizó los procedimientos de laboratorio de Mecánica de Suelos: ASTM D427-61 para el límite de contracción, ASTM D424-59 para el límite plástico y ASTM 423-66 para el límite líquido, de un suelo de sabana en muestras aleatorias a las profundidades de 0-15, 15-30, 30-45 y 45-60 cm. Se utilizó el análisis de regresión para interpretar la proporción de la variancia entre parámetros. Los resultados indicaron valores de: límite de contracción de 4,22–5,20%, límite plástico de 12,92–14,04%, límite líquido de 16,94–19,43%, índice de plasticidad de 3,59–5,78% e índice de friabilidad de 8,63–8,84%. Se concluye que los valores concuerdan con la bibliografía y el rango de uso agrícola se encuentra entre 8% y 15% para el suelo en estudio.

Bajo un esquema conceptual que combina principios de las teorías: Elección Racional, Movilización de Recursos, Privación Relativa, Identidades Colectivas y Capital Social, se plantea la hipótesis que la participación de dichas comunidades en el subprograma está determinada por una serie de factores internos y externos en donde resaltan la representación social que tienen del subprograma, el cálculo racional de la acción, la tradición participativa y el apoyo organizativo de grupos voluntarios. Se empleó la perspectiva etnomedotológica en la realización de entrevistas en profundidad, de donde se extrajo como conclusión que existen factores comunes que condicionan la participación en ambas comunidades, tales como la reafirmación de una identidad femenina entendida como un incentivo para la acción, una representación colectiva positiva sobre la medicina natural y la presencia de recursos organizativos externos proporcionados por las escuelas ubicadas en cada comunidad, por grupos eclesiales de base y por la misma Iglesia Católica como agente promotor del subprograma.

    Full Text Available En el estado Nueva Esparta, Venezuela, la pesca del pulpo Octopus vulgaris es considerada por los pescadores artesanales como una actividad alternativa para diversificar la producción y aumentar los ingresos, pero en los últimos años han venido experimentando fluctuaciones interanuales considerables. La necesidad de gestionar el recurso de una forma racional y responsable, impuso analizar algunos aspectos de la reproducción, crecimiento, mortalidad y pesquería, de modo que sirvan de base científica para llevar a cabo estrategias de manejo. Con el fin de cumplir con los objetivos, las muestras se obtuvieron durante la temporada de pesca junio-diciembre 2012 con una periodicidad semanal. A cada uno de los especímenes se le registró la longitud del manto (Lm, peso total (Pt, sexo y estado de madurez gonádica. Se procesaron 1 268 machos de 9 a 25cm Lm y 818 hembras de 9 a 22cm Lm; la proporción de sexo mensual fue diferente a uno excepto junio y agosto, con un alto porcentaje de maduros en ambos sexos. Las tallas mínima y media de madurez sexual en machos fueron: 11cm (428g y 16cm (1 142g; mientras que en hembras 12cm (476g y 15.35cm (844g. La relación longitud-peso de machos: Pt=0.7994*Lm2.62 y hembras: Pt=1.4552*Lm2.33 expresaron un crecimiento alométrico minorante. La estimación del crecimiento se basó en el análisis de la distribución de frecuencia de longitudes, para ello se usó el software FiSAT.

    Full Text Available El alga rodofita, Pterocladiella caerulescens, ha sido poco estudiada en Venezuela, a pesar de que a nivel mundial se ha determinado su alto rendimiento en la producción de agar. En este trabajo, se describen las estructuras vegetativa y reproductiva (cistocarpo, tetrasporangio y espermatangio de una población de P. caerulescens ubicada en los sustratos rocosos de la zona intermareal de la bahía de Boca de Río, Isla de Margarita, durante el mes de noviembre 2013 a mayo de 2014. Doscientos ejemplares, formando agrupaciones cespitosas, fueron recolectados con estructuras de fijación, realizándose el desprendimiento con la ayuda de cuchillo y espátulas, preservándolas en solución de formaldehido al 4% v/v con agua de mar y almacenadas en frascos de vidrio. El análisis mediante microscopía óptica reveló en los ejemplares femeninos, la presencia de un cistocarpo solitario con una placenta unilocular en cuyo centro de la cavidad se dispone el carpogonio, lo que permitió la identificación de la especie como Pterocladiella caerulescens (Kützin Santelices & Hommersand, perteneciente a la familia Pterocladiaceae. Esta especie no había sido registrada en la zona marino-costera del estado Nueva Esparta, siendo identificado por primera vez en los estados Falcón y Carabobo, posteriormente en el estado Sucre, por lo que con este registro se amplía el área de distribución de la misma en Venezuela.

Un recurso judicial como el de interpretación abstracta de la Constitución, creado por la Sala Constitucional sin soporte en la Constitución, en manos de un Juez Constitucional totalmente dependiente del mismo Poder Ejecutivo, sin autonomía ni independencia algunas, ha resultado ser un instrumento utilizado para cambiar y ajustar la Constitución a la voluntad del Ejecutivo, al margen de los procedimientos de reforma y de la voluntad del poder, afianzando el autoritarismo

    Full Text Available Durante os últimos 30 anos, o aumento da população humana no Amazonas introduziu a necessidade de produção adicional de alimentos e levou o governo do estado a desenvolver programas para aumentar e melhorar a produção agrícola. A produção de hortaliças não tradicionais apresentou vários problemas desconhecidos para os agricultores da região, uma vez que estas culturas não são bem adaptadas às condições locais. A suscetibilidade a insetos, fungos e outras pragas, e a competição com vegetação nativa vem forçando os agricultores a usar intensivamente os agrotóxicos. Os agricultores não estavam preparados para o uso adequado desta tecnologia ignorando os riscos dos agrotóxicos para saúde humana e o ambiente. Os agricultores não usam equipamento de proteção individual, porque é caro, desconfortável e inadequado para o clima quente da região. A falta treinamento e o escasso conhecimento sobre os perigos dos agrotóxicos contribuem para a manipulação incorreta durante a preparação, aplicação e disposição das embalagens vazias. Nestas condições, a exposição dos agricultores, suas famílias, consumidores e ambiente é alta. Como um primeiro passo para o entendimento deste problema e a proposição de soluções é proposta a realização de uma avaliação integrada de risco. As três fases do processo, formulação de problema, avaliação da exposição, e caracterização de risco são detalhadas. Programas de educação, treinamento e informação fazem parte das estratégias para a redução do risco do uso de agrotóxicos permitindo o desenvolvimento de uma agricultura ambientalmente sustentável.During the last 30 years, the increase of the human population in the Amazon introduced the need for additional food production and caused the state government to implement programs to increase and improve agricultural production.

    Full Text Available En América del Norte, los grupos indígenas se han identificado como una población con un riesgo elevado de ser portadora de Streptococcus pneumoniae, así como de desarrollar enfermedad neumocócica invasora. Sin embargo, hay poca información con respecto a los indígenas de Latinoamérica. En el presente estudio se evaluó el estado de portador nasofaríngeo y la distribución de los serotipos de S. pneumoniae en madres e hijos de la población panare de Venezuela. Durante el mes de mayo de 2008 se obtuvieron 148 muestras nasofaríngeas de 64 madres y 84 niños menores de 5 años pertenecientes a 8 comunidades panare. Mediante procedimientos estándares se identificaron 65 cepas de S. pneumoniae. Dichas cepas fueron tipificadas por PCR múltiple, y sus patrones de sensibilidad a los antimicrobianos se determinaron por el método de difusión con discos. El 11% de las madres y el 69% de los niños eran portadores de S. pneumoniae. Los serotipos 6B (49%, 33F (21,5%, 6A (6%, 19A (3,1% y 23F (1,5% fueron los más frecuentes. El mismo serotipo se identificó en 3 de los 6 grupos madre-hijo/s colonizados. Todas las cepas fueron sensibles a la penicilina y el 13,7% fue resistente a los macrólidos. La elevada tasa de colonización en la población panare sugiere que los niños presentan un alto riesgo de desarrollar enfermedad invasora por S. pneumoniae; por lo tanto podrían beneficiarse de la vacunación. Cuatro serotipos de la vacuna conjugada (6B, 6A, 19A y 23F, que representaron el 58% de las cepas aisladas, estaban presentes en la población al momento del estudio.

    Full Text Available The current increase of the population with older age poses new urgencies in social aspects, which leads us to redefine our generational identity. The world of the elderly has changed, increasingly taking more active roles within the family dynamics where, with adjustments for mutual assistance, have led to a considerable number of them to become “caregiver grandparents” or “kangaroo grandparents”, to get in charge of their grandchildren. This task, which involves devotion from the grandparent’s part, also involves impacts on his physical and mental health that complicate his living conditions (material and symbolic. To understand this dynamic, this study aimed to interpret the experiences of three “kanguroo grandparents” from Cumana, Sucre State, Venezuela, under a phenomenological qualitative approach, with field design and descriptive-interpretatiive level. The techniques used were observation and in-depth interviews with three grandparents and their families, to deconstruct reality through categorized protocols and triangulated, which allowed the construction of a global structure of the phenomenon. As main findings, it was revealed the existence of a close relationship between the formation of matriarchal families, with a progressive process of feminization of poverty. Filial piety became the suitable channel to keep hogging and exploitative relations, that created stress and various conflicts. In addition, the displacement of patterns of breeding was evidenced that not only redefines parenting roles, but distorts the foreseeable development of families.

For the study of service quality two fundamental props exist: the internal and the external clients. The present investigation analyzes the service quality of fast food businesses from the participation of the avant-garde employee, in the specific case of businesses located in Libertador Municipality of Merida State, Venezuela. For this purpose, the integral model of quality breaches of the service and the scale of Dineserv were applied during the second semester of 2014. In this regards, a representative sample of the population of managers, employees and external customers of fast food businesses was selected, and a survey was applied to each of them. Compliance with the standards of the service employees was verified, as well as the positive correspondence between this performance and the levels of quality of service perceived by the user. To confront the low perception of the performance of the employee, rewards, recognition and multiple and varied stimulus should be implemented in order to motivate for a continuous improvement of the quality of service.

La finalidad de este ensayo se centra en demostrar, desde el punto de vista del análisis de las políticas públicas, cómo la política de auxilios financieros, intervención y/o liquidación de instituciones bancarias entre 1994 y 1995, si bien respondían al deseo de proteger los ahorros del público y las empresas, su manejo deficiente, en términos económicos, no hizo sino reflejar los conflictos entre los niveles de decisión técnica y política. La preeminencia de los elementos de carácter político sobre los de carácter técnico, ahondó más aún la crisis y demostraron que la experiencia acumulada en crisis anteriores de poco o nada sirvieron para dominar la crisis en el sistema de pagos venezolano. Se concluye, que el sistema de vigilancia y control bancario junto a la estructura del sistema bancario venezolano ameritan un severo reajuste institucional.

    Full Text Available Introducción. La enfermedad de Chagas y la leishmaniasis son patologías de gran importancia en salud pública debido a su alta frecuencia y amplia distribución en América Latina. El estudio de los animales reservorios es vital para una comprensión global de estas enfermedades. Objetivo. En el presente trabajo nos propusimos identificar parásitos de la familia Trypanosomatidae en animales silvestres con la finalidad de establecer posibles relaciones debidas a la coinfección. Materiales y métodos. En El Carrizal, un área rural del estado Mérida, Venezuela, entre julio de 1998 y febrero de 2000 se realizaron capturas sistemáticas de animales silvestres con la finalidad de poner en evidencia la presencia de parásitos pertenecientes a la familia Trypanosomatidae. Las capturas fueron realizadas con trampas caseras tipo Tomahawk, colocadas 15 noches por mes durante el periodo del estudio. A los animales capturados se les practicó punción cardiaca bajo anestesia para extracción de sangre con la cual se realizaron los siguientes estudios: examen en fresco, extendido para coloración con Giemsa y cultivo en agar-sangre. Se realizaron algunos xenodiagnósticos. Los aislamientos obtenidos por medio de cultivo se identificaron por medio de análisis de restricción e hibridación con sondas específicas. Resultados. Se capturaron y estudiaron 215 animales pertenecientes a tres especies: Rattus spp. (135, Sigmodon hispidus (73 y Didelphis marsupialis (7. Igualmente, se identificaron tres especies de Trypanosomatidae: Leishmania (V guyanensis, Trypanosoma cruzi y Trypanosoma lewisi.

    Full Text Available El trabajo analiza la geomorfología de dunas costeras longitudinales del Istmo de Médanos, costa noroccidental de Venezuela. La metodología consistió en consultas bibliográficas, cartográficas, fotogramétricas y satelitales, trabajos de campo y análisis sedimentológico. Los resultados indican que estas dunas están compuestas por arenas de grano fino en un 84.6%, muy bien seleccionadas en más del 60%, principalmente subangulares, con asimetría negativa predominante, distribución leptocurtica, y bajo contenido de carbonato de calcio cercano al 10%. Los datos sugieren que los sedimentos son de origen terrígeno y escasa distancia de transporte hasta el lugar de acumulación. Los vientos predominantes actuales son del noreste, con componentes direccionales secundarios que retrabajan los sedimentos generando dunas transversales, barcanas y longitudinales; las dunas longitudinales son paralelas a la dirección del viento y se presentan colonizadas por vegetación xerofítica favorecida por la inactividad de las mismas. Estas dunas se originaron probablemente por una conjunción de factores como: disponibilidad de sedimentos en una amplia llanura costera relacionada con un nivel marino regresivo, vientos fuertes y persistentes, orientación oblicua de la costa respecto a la dirección del viento, una topografía continental favorable adyacente a la playa, bajo condiciones climáticas distintas a las actuales.

    This study evaluates the daily dietetic ingestion of Hg and some nutrients of pre-scholar children from eight communities of Amazonas state, Brazil. Some children from each community were selected and their diets (24 hours total consumption) were collected by the duplicate quantity method and a pool of diets composed for each of these communities. The diet samples were analysed for the Hg total content by a CV AAS linear accelerator and neutron activation analysis for determination of Ca, Fe, K, Se and Zn micro nutrients. Both analytical methodologies precision and accuracy were validated using the certified reference materials analysis. The provisional tolerable weekly ingestion (PTWI) for Hg and the daily micro nutrient ingestion were calculated for each group, considering an 10 kg average weight for each child. The obtained results for all diets were shown the inadequacy prevail for the evaluated micro nutrients, and some communities exceeded the limit of 5 {mu}g Hg/kg of body weight (PTWI). Those results suggested that the nutritional education program must be implemented at those communities, aiming the better utilization of the local food natural resources. (author)

    Full Text Available El área de La Macolla se localiza al SW del faro homónimo en la costa NW de Paraguaná, Estado Falcón, Venezuela. El objetivo del trabajo es abordar una posible explicación de evolución geomorfológica, a partir de los indicadores disponibles en el campo, tales como terraza marina, manglar y barrera o cordón litoral, además de caracterizar los ambientes sedimentológicos distintivos. Se trata de una antigua bahía bordeada por un escarpe de terraza constituido por calizas fosilíferas con un promedio de altura de 80 cm. Este escarpe domina un área de 9.6 ha de planicie lodosa o “mud flat” y una barrera litoral de 3.5 ha. La fracción limosa predominante en los sedimentos de la planicie lodosa y del área de manglar se interpretan como evidencias de condiciones más húmedas que las actuales, que permitieron la meteorización de las calizas circundantes, una escorrentía superficial y el consiguiente transporte hasta las partes más bajas, donde la vegetación halófita se instaló. La evolución de la bahía a llanura cenagosa se atribuye a fluctuaciones del nivel marino y al cierre de cordones litorales por transporte sedimentario.

In general, the total Hg and MeHg median ranges in hair were similar (0.91 to 1.71 mg kg-1 except for the São Jose neighborhood, which was lower (0.16 mg kg-1. De spite the fact that the Manaus population consumes fish as part of the normal dietary intake, the Hg hair levels were below the level for an adult population not exposed to mercury (2.0 mg kg-1. These data were compared to demographic, socioeconomic information and eating habits of the families that took part in the study. The results were also compared to other published data from the Amazon region, other regions of Brazil and other countries. Future studies to set Hg and MeHg levels in hair of children in Brazil should take into account and assess the diversity of the country, mainly in terms of eating habits, socio-economic and cultural aspects.O presente estudo avaliou o teor de Hg e MeHg em amostras de cabelo de 201 crianças de 2 aos 7 anos de idade, residentes em seis bairros da cidade de Manaus, Amazonas, Brasil.

Las deficiencias de anticuerpos son las IDPs más comunes y dentro de estas la agammaglobulinemia congénita representa el 10%, siendo un 85% ligada al cromosoma X, existiendo también formas autosómicas recesivas. La agammaglobulinemia ligada a X (ALX consiste en la ausencia casi absoluta de linfocitos B, ocasionando incapacidad de sintetizar anticuerpos y una alta susceptibilidad a la adquisición de infecciones, con respuesta a vacunas disminuida o ausente. Se presenta el caso de un escolar masculino de 8 años de edad quien desde los 5 meses presentó infecciones a repetición principalmente por bacterias extracelulares encapsuladas. Estudios paraclínicos revelaron hipogammglobulinemia persistente con subpoblación de linfocitos B muy disminuida y conservación de linfocitos T en sangre periférica. El estudio molecular reportó la mutación R525X en el exón 16 del gen TirosinKinasa de Bruton (BTK en el paciente y su madre, más no en la abuela, lo que confirmó el diagnóstico de ALX y permitió concluir que se trataba de una mutación de novo en la madre. Actualmente recibe tratamiento con Inmunoglobulina por vía endovenosa, disminuyendo la frecuencia y severidad de episodios infecciosos. El diagnóstico precoz a través del reconocimiento de las señales de alarma de las IDPs, junto al tratamiento adecuado y vigilancia constante constituyen la mejor herramienta para el adecuado manejo de los pacientes con IDPs, logrando una disminución de los procesos infecciosos e inflamatorios y sus secuelas, así como también mejorar la calidad de vida y supervivencia.

    Amazona barbadensis is an endangered species of parrot living in northern coastal Venezuela and in several Caribbean islands. In this study, we sequenced full mitochondrial genome of the considered species. The total length of the mitogenome was 18,983 bp and contained 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, duplicated control region, and degenerate copies of ND6 and tRNA (Glu) genes. High degree of identity between two copies of control region suggests their coincident evolution and functionality. Comparative analysis of both the control region sequences from four Amazona species revealed their 89.1% identity over a region of 1300 bp and indicates the presence of distinctive parts of two control region copies.

    Full Text Available La globalización económica ha acentuado la desigualdad y la vulnerabilidad a las enfermedades tropicales en todo el mundo. La población del Amazonas venezolano y particularmente la población indígena del interior del Estado es uno de los segmentos más desfavorecidos de las Américas a juzgar por los indicadores de salud. Las tasas de mortalidad infantil observadas en poblaciones indígenas en áreas remotas indican que han sido afectadas por la globalización de las enfermedades, pero no se han beneficiado de la globalización de la salud. Por otra parte, la globalización ha influido en las políticas públicas lo cual afectó la eficiencia de los programas de control de enfermedades tropicales en Amazonas. Un nuevo pacto mundial para el desarrollo sostenible de la aldea global es necesario, a través de la "globalización" de los valores y los derechos comunes de la humanidad. En Venezuela, nuevas políticas dirigidas hacia el subsector de salud indígena, más recursos y mayor autonomía de acción pueden ayudar a reducir las inequidades aquí descritas en el Amazonas venezolano.Economic globalization appears to be causing greater inequalities and increased vulnerability to tropical diseases around the world. The Venezuelan Amazon population, especially the rural indigenous population, displays among the worst health indicators in the Americas. High infant mortality rates in remote indigenous populations indicate that such communities have been affected by the globalization of disease, rather than favored by globalization of health. Globalization has also influenced public policies in the country, affecting the efficiency of control programs targeting tropical diseases. A new global pact for the sustainable development of the planet is needed, supported by the globalization of human values and rights. In Venezuela, new policies for the indigenous health sector, more resources, and greater autonomy could help reduce the inequities

    Full Text Available Perna viridis es un bivalvo procedente del Indo-Pacífico que habita en la zona intermareal y ha invadido varios ecosistemas de la costa norte del estado Sucre, Venezuela. Con la finalidad de realizar un estudio sobre las comunidades de moluscos asociadas a esta especie y sus relaciones tróficas, se llevaron a cabo muestreos bimensuales entre octubre/97 y agosto/98, en un banco natural de mejillones a dos metros de profundidad en la costa norte de la península de Araya (10°40’N -48°63’W. Los organismos fueron recolectados delimitando el área con una cuadrícula de 0.25 m². Se identificaron los organismos hasta la categoría de especies utilizando claves específicas para moluscos y bibliográficamente se les determinó categoría trófica.Se capturó un total de 1 235 individuos de P. viridis y asociados a la especie 3 163 especímenes pertenecientes al phylum Mollusca, contenidos en tres clases: Bivalvia,Gastropoda y Polyplacophora. Éstas estuvieron representadas por 50 especies correspondientes a 10 órdenes, 24 familias; para los gasterópodos se contabilizaron 25 especies, para los bivalvos 22 y tres para los poliplacóforos. Del total de las especies, 40% fueron filtradoras, 26% carnívoras, 24% herbívoras y el 10% restante presentó dos categorías.De las filtradoras las más representativas fueron: Perna perna, Musculus lateralis, Crassostrea rhizophorae y Ostrea equestris; en el grupo de los carnívoros dominaron tres especies de la familia Columbellidae:Mitrella lunata, Anachis obesa y Nitidella ocellata y para el grupo de los herbívoros destacaron dos especies de la familia Fisurellidae: Diodora cayenensis y D. minuta. Se registraron dos especies filtradoras-detritívoras, y tres especies herbívoras-filtradoras representantes del género C repidula. El alto porcentaje de filtradores sería un indicativo de que dentro de este sistema probablemente hay una mayor disponibilidad de fracciones alimenticias para este grupo

Atraídos por las oportunidades económicas, millares de hombres jóvenes han migrado a esa zona y su presencia en ella ha atraído, al mismo tiempo, a muchas trabajadoras sexuales. La situación, sumada a otros factores sociales, económicos y culturales, facilita la propagación de la infección por VIH y de otras ETS en el territorio. Más de 2 000 personas asistieron a los talleres sobre la prevención de la infección por VIH/ETS, que también se aprovecharon para reunir información sobre las prácticas sexuales en la zona minera. El estudio reveló prácticas sexuales de alto riesgo en todos los grupos estudiados. Antes de este proyecto de investigación se disponía de información epidemiológica escasa e incompleta sobre las infeccions por VIH/ETS en esa zona. Para el presente estudio se tomaron 893 muestras de sangre de habitantes de la localidad. Las pruebas realizadas revelaron una altísima frecuencia de infección sifilítica y de infección por VIH, virus de la hepatitis B y virus humanos linfotrópicos t de tipos I y II. Los resultados de los tallers sobre prevención y del estudio epidemiológico se usarán para crear un plan bien dirigido a largo plazo para la prevención de VIH/ETS en la zona de explotación minera de oro.

    Immigration to Venezuela is examined using census data with the focus on the period 1971-1981. A brief overview of trends since the beginning of the twentieth century is first presented. The analysis indicates that "immigration to Venezuela is clearly of a short-term nature. Flows follow job opportunities and adjust to the labour market and to the financial capacity of the exchange market. The large increase of migratory movements to Venezuela in the 1970's is characterized by a diversification of their places of origin and by a greater instability. To a large extent, the migrants are illegal, especially those coming from Colombia and the Caribbean islands. Because of the crisis of the early 1980's, which is now worsened by the down trend of both oil prices and the U.S. dollar, Venezuela has become less attractive to immigrants, particularly from neighbouring countries." The authors observe that migrants in Venezuela are not well integrated and may depart, disrupting the labor supply in certain technical and specialized occupations (SUMMARY IN ENG AND SPA) excerpt

    Full Text Available The bullfrog, Lithobates catesbeianus, is one of the one hundred worst invasive species in the world. Its introduction into the Venezuelan Andes is worrying due to the large number of endemic species that could be affected by its presence. We examined the dispersal of Lithobates catesbeianus in western Venezuela to identify the areas where follow-up and control are a priority to avoid further invasion. Based on data on absence and presence of the bullfrog, we updated its distribution and compared it to records from 2005 (46.001 km2 and 2010 (53.502 km2. The area invaded by 2013 was 76.417 km2, 1.6 times the distribution in 2005, growing at a rate of 3,041 km2 per year. Factors such as inclination of the terrain, presence of forests and bodies of fast moving water could be acting as barriers to further dispersal. Taking into account that the distribution of this species in Venezuela by 2013 was limited to the basins of the rivers Capazón, Las González and Quebrada La Sucia in Mérida state; the regions at the greatest risk of being invaded due to natural dispersal are downriver from these bodies of water. However, the risk of invasion exists due to human introduction in nearby areas similar to those currently inhabitedby the bullfrog. Our recommendations are the conservation and reforestation of forests in the area, the creation of early warning protocols for the areas at greatest risk of invasion, and the continuation of measures prohibiting the transportation of bullfrogs outside of their current distribution.

    1982-01-01

    Venezuela had an aggressive nuclear program when it was under a dictatorship in the 1950s, but it is currently assuming a wait-and-see stance. The country has one small research reactor, but it may have a reactor on-line in the mid-1990s. CONADIN, Venezuela's nuclear energy planning agency, has commissioned feasibility studies and requested proposals for a reactor-siting survey. A recent study for the Venezuelan state oil company suggests tha a natural-uranium, gas-cooled reactor could provide process steam to extract oil from the bituminous tar sands of the Orinoco Basin. Venezuela is also exploring for uranium reserves. 23 references, 1 figure, 2 tables

    Full Text Available Mercury is a toxic element used in the manufacture of energy-saving bulbs, which is a source of pollution both for the environment and humans when they are improperly disposed of. Mercury entering the organism is mainly eliminated by urinary excretion. The discard of energy-saving bulbs and its relation with mercury environmental exposure in Bella Vista population (Aragua, Venezuela was studied. Research was descriptive, correlational, cross-sectional and field. For a group of 36 possibly exposed and 37 control group individuals, the discarding methods for energy-saving bulbs were identified, mercury levels in urine by cold vapor spectrophotometry and creatinine levels by Jaffe modified method were quantified. Permissive limit for non-exposed persons is 5 μg Hg/g creatinine. Signs and symptoms associated with exposure to mercury were described and the variable discard of energy-saving bulbs with urinary mercury levels was related. An analysis of variance was applied on the results of urine mercury levels classified by study group (possibly exposed and control and age groups, with statistically significant differences for urine mercury levels classified according to study groups (p = 0.001 but not for age group (p = 0.946.

    Full Text Available Determination of bioelements concentrations in serum are considered very important, since they allow to establish reference levels that can be used to detect essential elements deficiency or poisoning by their excess. The aim of this study was to identify the serum levels of magnesium, iron and copper in a population of apparently healthy adults, residents of an urban area of Ciudad Bolivar, Bolivar State, The sample consisted of 57 individuals (28 men and 29 women that were not occupationally exposed residents in Ciudad Bolivar, aged between 25 and 60 years. Bioelements were determined by Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES after acid digestion of serum samples. The average concentration values (± SD of magnesium, iron and copper obtained were, respectively, 22 ± 3 mg.L-1, 1.1 ± 0.2 mg.L-1 y 1.0 ± 0.2 mg.L-1. Regarding the studied bioelement levels, only magnesium levels of men were significantly higher (p < 0.05 than the levels of women. The mean concentrations of bioelements were within ranges of reference values reported in the literature for healthy people, but significantly different (p < 0,05 to those from Merida, another region from Venezuela, and a possible consequence of changes in eating habits and environment conditions among these two Venezuelan regions.

    Full Text Available Beta-hemolytic streptococci of groups A (EBHGA, Streptococcus pyogenes, C (EBHGC and G (EBHGG induces the production of anti-streptolysin O antibodies (ASTO in infected individuals. In Venezuela, the most common tests used to measure these antibodies are bacterial toxins neutralizing and indirect (passive agglutination with latex particles. Individuals colonized by the aforementioned bacteria can remain as asymptomatic carriers. The purpose of this study was to determine ASO titers and frequency of beta-hemolytic streptococci in 203 students 10-15 years old from the municipality Francisco Linares Alcantara. The ASO titers were determined by neutralization and indirect (passive agglutination tests; EBH frequency was determined through the throat swab culture, which was performed on blood agar at 5%. It was found that 88.6% (180/203 and 53.2% (108/203 of the individuals had normal titers by the method of neutralization and agglutination, respectively. The most frequently isolated EBH belonged to G group (42%, followed by B (26%, A (11% and C (5% groups. There was a large discrepancy between the results from culture and serology. The Fisher exact test found no significant difference between the proportions of high titers for groups of healthy patients and asymptomatic carriers. These results indicate that the behavior of the ASTO titers is similar in both groups.

    Full Text Available The author reviews the malaria research program in Sucre State, Venezuela, taking an ecosystem approach. The goal was to determine which methods could have been introduced at the onset that would have made the study more ecological and interdisciplinary. Neither an ecosystem approach nor integrated disease control were in place at the time of the study. This study began to introduce an ecosystem approach when two contrasting ecosystems in Sucre State were selected for study and vector control methods were implemented based on research results. The need to have a health policy in place with an eco-health approach is crucial to the success of research and control. The review suggests that sustainability is low when not all the stakeholders are involved in the design and implementation of the research and control strategy development. The lack of community involvement makes sustainability doubtful. The author concludes that there were two interdependent challenges for malaria control: development of an ecosystem approach for malaria research and control, and the implementation of an integrated disease control strategy, with malaria as one of the important health issues.O autor faz uma revisão do programa de pesquisa sobre malária no Estado de Sucre, Venezuela, à luz de uma abordagem ecossistêmica. O objetivo era determinar quais métodos poderiam ter sido introduzidos no início do estudo para torná-lo mais ecológico e interdisciplinar. A fase inicial do estudo não incluía uma abordagem ecossistêmica ou controle integrado da doença, que só foram incorporados quando dois ecossistemas contrastantes no Estado de Sucre foram selecionados para pesquisa, junto com um método de controle de vetores com base nos resultados. Uma política de saúde bem-definida com uma abordagem ecossistêmica é crucial para o sucesso de uma estratégia de pesquisa e controle. Esta revisão sugere que a sustentabilidade é baixa se todos os atores não estiverem

    No federal government officials showed up at the Oct. 29 ceremony to lauch the Responsabilidad Integral program of Asoquim, the Venezuelan chemical industry association. But that did not discourage industry representatives. Industry has tried to keep the Ministry of Environment Affairs involved as much as possible, says Danay Zoppi de Perez, corporate v.p. with Grupo Quimico. But industry was proud to be doing it anyway, despite the absence of government. It's a private, proactive initiative. Asoquim's program is based on the six Responsible Care codes. At the ceremony, 56 companies from Asoquim's membership of 150, which represents 90% of chemicals production in the country, signed on. Signatories include stateowned Petroquimica de Venezuela (Pequiven), domestic private-sector firms, and most of the multinationls operating in Venezuela.

    Strong performances by small and medium sized oil companies in Venezuela have contributed to the success of its oil industry. This paper considers the historical progress of the industry since its nationalisation twenty-one years ago, charting its attractiveness to investors and plans for expansion. Its very success has brought the Venezuelan oil industry into conflict with OPEC's quota system, which it argues, needs to be charged. (UK)

    Percent variation of the consumer price index (CPI) is the inflation indicator most widely used. This indicator, however, has some drawbacks. In addition to measurement errors of the CPI, there is a problem of incongruence between the definition of inflation as a sustained and generalized increase of prices and the traditional measure associated with the CPI. We use data from 1991 to 2005 to estimate a complementary indicator for Venezuela, the highest inflation country in Latin America. Late...

    2007-07-01

    Venezuela is an important player in the energy world, because of its hydrocarbons reserves. The process for calculating oil and associated gas reserves is described bearing in mind that 90% of the gas reserves of Venezuela are associated to oil. Likewise, an analysis is made of the oil reserves figures from 1975 to 2003. Reference is also made to inconsistencies found by international experts and the explanations offered in this respect by the Ministry of Energy and Petroleum (MENPET) and Petroleos de Venezuela (PDVSA) regarding the changes that took place in the 1980s. In turn, Hubbert's Law is explained to determine peak production of conventional oil that a reservoir or field will reach, as well as its relationship with remaining reserves. Emphasis is placed on the interest of the United Nations on this topic. The reserves of associated gas are presented along with their relationship with the different crude oils that are produced and with injected gas, as well as with respect to the possible changes that would take place in the latter if oil reserves are revised. Some recommendations are submitted so that the MENPET starts preparing the pertinent policies ruling reserves. (auth)

    Since 1990, ACCSI has worked to safeguard the rights of people living with HIV/AIDS in Venezuela. The Pan American Health Organization (PAHO) had recognized ACCSI's program by 1992, enabling the nongovernmental organization (NGO) to establish fixed office hours during which it can receive clients. ACCSI does not distinguish between people living with HIV/AIDS and others, but considers it important to regulate AIDS as a public health issue within the context of human rights and ethics. Almost all of the Legal Office's initial cases were related to discrimination in the workplace, health centers, and educational institutions, but the ACCSI now also addresses family problems related to adoption, insurance, and inheritance, among others. To cope with the increase in service caseload, services have been extended through collaboration with specialized organizations concerned with human rights, women, children, prisons, and indigenous people. ACCSI influences governmental policy-making through its participation in the National AIDS Program. Moreover, ACCSI's networking activities ensure that the topic of HIV/AIDS and human rights is now always included in seminars and conferences in Venezuela, even when they are concerned with sexually transmitted diseases or other medical issues. Almost every time the press report upon AIDS, they consult the NGO. Everyday more people in Venezuela are standing up for their rights and denouncing discrimination against people infected with HIV.

    The incidence of type 2 diabetes (T2D) and its economic burden have increased in Venezuela, posing difficult challenges in a country already in great turmoil. The aim of this study was to review the prevalence, causes, prevention, management, health policies, and challenges for successful management of diabetes and its complications in Venezuela. A comprehensive literature review spanning 1960 to 2015 was performed. Literature not indexed also was reviewed. The weighted prevalence of diabetes and prediabetes was estimated from published regional and subnational population-based studies. Diabetes care strategies were analyzed. In Venezuela, the weighted prevalence of diabetes was 7.7% and prediabetes was 11.2%. Diabetes was the fifth leading cause of death (7.1%) in 2012 with the mortality rate increasing 7% per year from 1990 to 2012. In 2012, cardiovascular disease and diabetes together were the leading cause of disability-adjusted life years.T2D drivers are genetic, epigenetic, and lifestyle, including unhealthy dietary patterns and physical inactivity. Obesity, insulin resistance, and metabolic syndrome are present at lower cutoffs for body mass index, homeostatic model assessment, and visceral or ectopic fat, respectively. Institutional programs for early detection and/or prevention of T2D have not been established. Most patients with diabetes (∼87%) are cared for in public facilities in a fragmented health system. Local clinical practice guidelines are available, but implementation is suboptimal and supporting information is limited. Strategies to improve diabetes care in Venezuela include enhancing resources, reducing costs, improving education, implementing screening (using Latin America Finnish Diabetes Risk Score), promoting diabetes care units, avoiding insulin levels as diagnostic tool, correct use of oral glucose tolerance testing and metformin as first-line T2D treatment, and reducing health system fragmentation.

While the number responding to the amnesty was small relative to expectations, the majority of illegals appeared to have regularized their status. For the first time it was possible to assess objectively the characteristics of the undocumented population. Moreover, the problem of illegal migrants seems to have been temporarily solved, a result of both the amnesty and the country's declining economic activity."

Results. 27.5% of individuals had low levels of Apo A-I, 45.2% high Apo B and 60.6% high Apo B/Apo A-I ratio. Serum levels of apolipoproteins and Apo B/Apo A-I ratio did not vary with age or gender, while the ratio HDL cholesterol/Apo A-I decreased with the age. Obese individuals, smokers, hypertensive, hypercholesterolemics, hypertriglyceridemics or with low HDL cholesterol showed higher Apo B and Apo B/Apo A-I ratio. Older individuals, smokers or individuals with increased LDL cholesterol and triglycerides showed lower HDL cholesterol/Apo A-I ratio. Consumption of three or more alcoholic drinks/day was associated with decreased Apo B. Conclusions. These results show high prevalence of altered apolipoprotein profile, which is associated with major cardiovascular risk factors. The results support the inclusion of the evaluated apolipoproteins in laboratory determinations made in public health centers in Venezuela.

    The Yellow-shouldered Amazon (Amazona barbadensis) is the sole parrot of the genus Amazona that inhabits only dry forests. Its population has been dropping; therefore it has been the topic of many studies and conservation efforts. However, the phylogenetic relationship of this species to potential relatives classified within the Yellow-Headed Amazon (YHA) complex are still not clear. Therefore, we used more extensive data sets, including the newly sequenced mitochondrial genome of A. barbadensis, to conduct phylogenetic analyses. Various combinations of genes and many phylogenetic approaches showed that A. barbadensis clustered significantly with A. ochrocephala ochrocephala from Colombia and Venezuela, which created the Northern South American (NSA) lineage, clearly separated from two other lineages within the YHA complex, the Central (CA) and South American (SA). Tree topology tests and exclusion of rapidly evolving sites provided support for a NSA+SA grouping. We propose an evolutionary scenario for the YHA complex and its colonization of the American mainland. The NSA lineage likely represents the most ancestral lineage, which derived from Lesser Antillean Amazons and colonized the northern coast of Venezuela about a million years ago. Then, Central America was colonized through the Isthmus of Panama, which led to the emergence of the CA lineage. The southward expansion to South America and the origin of the SA lineage happened almost simultaneously. However, more intensive or prolonged gene flow or migrations have led to much weaker geographic differentiation of genetic markers in the SA than in the CA lineage.

    This article presents information on the age structure and the level of female fertility obtained on the basis of a sample of the yanomami population (653 individuals) residing in the Venezuelan margin of Sierra Parima. Data was gathered through a survey which had the character of a retrospective demographic investigation, consisting of a series of questions about past events. The survey was conducted almost in its entirety by an American missionary who has resided in the area since 1972. The study took place from March 1981 to March 1982. To estimate the number of births per anum Mortara's method was used. This method consists of plotting on a graph the number of live births according to the mother's age and adjusting the resulting curve so that irregularities disappear. The population observed was very young, over 50% were less than 15 years old and the mean age was 18 years. The total fertility rate reach 7.76 children/woman while the age distribution of rates showed that fertility began at early ages and started to decrease only after age 30. The comparison of the obtained parity averages with existing records of fertility rates suggest that the information given for the year previous to the survey was the most accurate. The importance of maintaining reliable and continuous records of live births is stressed. Results are illustrated in tables and charts.

    This paper analyses the health services regionalization process in the State of Amazonas through a case study covering the health sub-region Manaus Surroundings. This is a qualitative, descriptive and analytical research, which data were collected using interviews, documents and Internet reviews, oriented by the guiding concept of health regionalization. Study findings revealed a social setting dominated by asymmetry, verticality, competitiveness and fragile multilateral relations among municipalities, associated to a bureaucratic profile of local institutions operating in the region under study. The political agents have limited acknowledgement of the sociopolitical and institutional conditions in which they operate. They usually impute healthcare networks' management and operational issues to the natural and geographical characteristics of the Amazon region, but their financing, governance and technical capacity are insufficient to overcome them.

    Reducing tropical deforestation is a major climate and development issue: forest clearing is responsible for roughly a fifth of greenhouse gas emissions, and the forest-dependent poor number over a billion. In the runup to the Copenhagen climate summit, REDD – reducing emissions from deforestation and (forest) degradation by providing incentives to tropical forest countries – has been touted as one of the most cost-effective mitigation mechanisms on the table. But the benefits would be only temporary if forests saved today are cleared once incentives cease. Would the expense of maintaining such incentives over decades raise the price to uncompetitive levels? A forest reserve in Amazonas, Brazil, offers some of the first real-world data on the costs of REDD. Even with pessimistic assumptions about future pressures, the project's carbon cuts look highly affordable.

    International Nuclear Information System (INIS)

    Silva, P.

    1991-01-01

    This paper reports on the natural gas outlook for Venezuela. First of all, it is very important to remember that in the last few years we have had frequent and unforeseen changes in the energy, ecological, geopolitical and economical fields which explain why all the projections of demand and prices for hydrocarbons and their products have failed to predict what later would happen in the market. Natural gas, with its recognized advantages over other traditional competitors such as oil, coal and nuclear energy, is identified as the component that is acquiring more weight in the energy equation, with a strengthening projection, not only as a resource that covers demand but as a key element in the international energy business. In fact, natural gas satisfies 21% of overall worldwide energy consumption, with an annual increase of 2.7% over the last few years, which is higher than the global energy growth of other fossil fuels. This tendency, which dates from the beginning of the 1980's, will continue with a possibility of increasing over the coming years. Under a foreseeable scenario, it is estimated that worldwide use of natural gas will increase 40% over the next 10 years and 75% on a longer term. Specifically for liquid methane (LNG), use should increase 60% during this last decade. The LPG increase should be moderate due to the limited demand until 1995 and to the stable trends that will continue its use until the end of this century

    Full Text Available In the above article author describes evolution of legal regulation of international commercial arbitration in Venezuela. Author cites statistics of arbitration centers in Venezuela activities. In past two decades many Latin American countries have reformed their arbitration law. In an effort to modernize its arbitral institutions several Latin American countries adopted Model Law on International Commercial Arbitration of the UN Commission on International Trade Law (UNCITRAL. In addition, many Latin American countries have adopted the monistic system. Author pays detailed attention to this issue, discusses concept of a monistic system - a system in which a unique set of rules governs both domestic and international arbitration. Author argues that legal system of Venezuela fits this definition. Venezuelan law on arbitration in 1998 makes no distinction between domestic and international arbitration. Arbitration was included in judicial system under the Constitution of Venezuela of the 1999. Art. 258 of the Venezuelan Constitution states that arbitration, conciliation and mediation are alternative ways of resolving disputes.

    Necropsies were conducted on a female blue-fronted Amazon (Amazona aestiva) and a female yellow-headed Amazon (Amazona oratrix) that died after depression, ruffled feathers, diarrhea, and biliverdin in the urine. Gross and microscopic examinations revealed multifocal necrosis in the liver, spleen, lungs, kidneys, intestines, and heart caused by acute bacteremia. Yersinia pseudotuberculosis, serogroup O:1a, was isolated by culturing from the visceral lesions in the liver, intestines, and spleen. Virulence gene analysis showed the presence of the inv gene and the complete pathogenicity island: IS100, psn, yptE, irp1, irp2 ybtP-ybtQ, ybtX-ybtS, and int asnT-Int. Histopathologic findings and chemical analysis also demonstrated hepatic hemosiderosis. As has been demonstrated in other species, hemosiderosis may predispose Amazona spp. to systemic infection with Y. pseudotuberculosis after enteric disease.

    2015-06-01

    Full Text Available INTRODUCTION: In the State of Amazonas, particularly in the capital Manaus, meningitis has affected populations of different cultures and social strata over the years. Bacterial meningitis is caused by several different species and represents a major issue of public health importance. The present study reports the meningitis case numbers with different etiologies in Amazonas from January 1976 to December 2012. METHODS: Since the 1970s, the (currently named Tropical Medicine Foundation of Doutor Heitor Vieira Dourado [Fundação de Medicina Tropical Doutor Heitor Vieira Dourado (FMT-HVD] has remained a reference center in Amazonas for the treatment of meningitis through the diagnosis and notification of cases and the confirmation of such cases using specific laboratory tests. RESULTS: The foundation has achieved coverage of over 90% of the state medical records for many years. Between 1990 and 2012, meningitis cases caused by Haemophilus influenzae decreased with the introduction of the H. influenzae vaccine. Meningococcal disease previously had a higher frequency of serogroup B disease, but starting in 2008, the detection of serogroup C increased gradually and has outpaced the detection of serogroup B. Recently, surveillance has improved the etiological definition of viral meningitis at FMT-HVD, with enteroviruses, Epstein-Barr virus (EBV and varicella zoster virus (VZV prevailing in this group of pathogens. With the advent of acquired immunodeficiency syndrome (AIDS, cryptococcal meningitis has become an important disease in Amazonas. Additionally, infectious meningitis is an important burden in the State of Amazonas. CONCLUSIONS: Changes in the epidemiological profile for the different etiology-defined cases are the result of continuous epidemiological surveillance and laboratory capacity improvements and control measures, such as Haemophilus influenzae vaccination.

    Sporotrichosis is one of the most common subcutaneous mycoses in Venezuela. It is a granulomatous chronic infection with cutaneous or subcutaneous tissue lesions. Regional lymphatic involvement may be present; extracutaneous disease is rare. The causal fungus Sporothrix schenckii has been isolated from soil, vegetation, and animals on numerous occasions and in many localities throughout the world. The aim of this study is to describe clinical and epidemiological features of cases of sporotrichosis observed in Venezuela and review of the literature. We included the demographic data, clinical features, diagnostic methods, treatment, and follow-up of patients with sporotrichosis from 1963 to 2009, diagnosed at the Department of Medical Mycology. One-hundred and thirty-three sporotrichosis cases were diagnosed. Most patients were under the age of 30 years (66.15%). In 61.6% of them, the mode of transmission was not identified. The predominant clinical form in this population was lymphocutaneous (63.15%). Direct microscopic diagnosis was performed in 123 cases, and 57.9% yielded positive results for asteroid body. Sporotrichosis is an endemic subcutaneous mycosis in Venezuela. There are no reports to this date of disseminated forms of the disease, even amongst patients with acquired immunodeficiency syndrome. Direct microscopic examination of wet mount slides with saline solution or distilled water in the search for asteroid bodies is paramount. Saturated sodium and potassium iodine solutions continue to be extremely efficacious and affordable to most of our patients, therefore our treatment of choice. © 2013 The International Society of Dermatology.

  14. Venezuela opens up to explorers

    Kielmas, M.

    1995-01-01

    The opening of Venezuela's first exploration bidding round since oil nationalisation in 1976 was a turning-point in the country's energy policy. The state oil company, Petroleos de Venezuela (PdVSA), has said that the bidding round could generate investment of some $11 billion eventually in development investment and that over the next 10 years, nearly 20 percent of a planned $55 billion, 10-year state oil company investment programme could also come from foreign or private sector oil investment. Should this optimistic prediction materialise, Venezuela, whose 2.75 million b/d oil production in October was some 400,000 b/d over its Opec quota, will remain both the dominant oil producer in Latin America and the top-ranking oil exporter to the US market. In May this year, Venezuelan oil exports topped 1.43 million b/d, or some 16.8 percent of the US market, compared with Saudi Arabia's 15.7 percent. (author)

    Full Text Available En Venezuela, los gobiernos locales junto con el gobierno nacional, crearon un sistema nacional de salud paralelo, Misión Barrio Adentro (MBA, ubicando a unos 33.000 profesionales de la salud, inicialmente cubanos, en vecindarios de bajos ingresos. A través de la etnografía y entrevistas, se concluye que MBA proporcionó acceso a la atención médica y logró obtener apoyo popular a consecuencia de: movimientos sociales de los pobres; cooperación entre trabajadores comunitarios, residentes, profesionales de salud y funcionarios públicos; la integración de la atención médica con programas sociales y económicos; la ubicación de médicos como residentes en barrios pobres; interacciones positivas y equitativas médico-paciente; el papel clave de los Comités de Salud; y el impacto de la hostilidad de la prensa, un segmento grande de los médicos venezolanos y la oposición en transformar a la salud en un tema político esencial. Todo esto nos sugiere que el Estado puede confrontar las inequidades de salud cuando se unen perspectivas teóricas de la medicina social y la epidemiología crítica con los saberes populares dentro de las comunidades afectadas. Estructuras institucionales flexibles, no burocráticas y creativas aumentan la efectividad de las intervenciones.

  1. Importance of energy efficiency in Venezuela

    International Nuclear Information System (INIS)

    Corrie, R.

    1991-01-01

    Venezuela's economic development relies heavily on oil. The nation's energy production equals 3.5 million barrels of oil equivalent (boe) per day. Oil comprises 71% of the energy Venezuela produces, natural gas 20%, hydro 9% and coal 1%. Of the energy produced, Venezuela exports three quarters and consumes the remainder. Over 99% of Venezuela's energy exports are crude oil and oil products. Economic problems have constrained Venezuela's development in recent years. Saddled with an external debt of $US 32 billion, Venezuela will continue to encounter barriers for years to come. The nation is, however, in the process of restructuring its economy. As part of this process, the Venezuelan government has begun to integrate opportunities for improving the efficiency of its energy use. As a major oil producer and exporter, Venezuela is conscious of its responsibility to the international community to limit its emissions of energy-related CO 2 into the atmosphere. For this reason, the Venezuelan government is in the process of creating a program to conserve and ration the use of energy. This effort incorporates a number of measures including the substitution of natural gas for liquid fuels for all end uses (including transportation activities), the increased reliance on hydropower in the generation of electricity and the reduction of waste in the production of natural gas to 2% of the economically recollectable volume

  2. Quality of democracy in Venezuela

    Directory of Open Access Journals (Sweden)

    Daniel H. LEVINE

    2013-01-01

    Full Text Available Discussions of democracy in contemporary Venezuela lack a settled definition of the subject, how to study it, or indeed of what counts as «democracy» in the first place. The regime has been described as everything from participatory democracy, hybrid, mixed, and personalist to populist, illiberal, or no longer democratic but rather competitive authoritarian. The goal of this article is to measure the quality of democracy in Venezuela, within the terms of a procedural concept of democracy as detailed in our earlier work. Empirical measurement of the quality of democracy on five dimensions (electoral choice, participation, responsiveness, accountability, sovereignty reveals a low level overall and deep institutional weakness under a personalist leadership, with little change from 2005 to 2010. Future scenarios, after the 2012 presidential election result, include reinforcement of authoritarian trends, open militarization, liberalization and institutional strengthening, or long term volatility and polarized conflict. All scenarios are contingent on the health of President Chávez, who is a central unifying factor for his movement and regime

    Full Text Available OBJECTIVE: To describe the epidemiological and clinical characteristics of Venezuelan pediatric patients with multiple sclerosis (MS. METHODS: Database records from the National Program for MS were searched for patients with an established diagnosis of MS whose first symptoms appeared before age 18. RESULTS: The national database held records of 1.710 patients; 3.8% had onset of the first symptoms before age 18. 46.7% were boys, yielding an F:M ratio of 1.13:1. Many children had a disease onset characterized by motor impairment (30.7%, brainstem/cerebellum and spinal cord affectation (27.6%, headache (26%. Less frequent symptoms were sensory symptoms (8% and optic neuritis (7%. DISCUSSION: Pediatric MS patients in Venezuela represent a significant proportion of all MS cases. The clinical pattern is characterized by motor symptoms at onset, and predominantly monosymptomatic presentation with a relapsing-remitting pattern. This is the first systematic attempt to estimate the prevalence of pediatric MS in Venezuela.

    This paper reports on Venezuela's expansion by state oil company PDVSA has gone from a mere concept a year ago to a well-defined plan. The five-year project that began this year and runs through 1995 received a $4-billion upgrading last fall to $25 billion. Money will be spent in increments of $5 billion/year, and all sectors are involved. Largest share, about $10.5 billion, will go to upstream projects, with $6 billion to be invested in refining, $6 billion in petrochemicals, $1.5 billion in coal and $800 million in domestic marketing. PDVSA intends to finance most of the spending directly from its cash flow. The upstream spending will go toward boosting oil production to more than 3.6 MMbpd by the beginning of 1996, with capacity topping at 4.2 MMbopd. Such heavy spending should prove a boon to the Venezuelan economy. The oil industry constitutes 23% of Venezuela's GNP, accounts for 75% of governmental revenues and produces 70% of the nation's annual foreign exchange earnings. The Ministry of Planning already is forecasting a 7% leap in real growth of the GNP this year

    Venezuela's current economic and demographic situation is described. Venezuela is a major oil country, and the oil industry accounts for 90% of the country's foreign exchange, 70% of the government's revenues, and 15% of the gross domestic product. The economy experienced a sudden and high rate of economic growth in the mid-1970s as a result of high oil prices; however, in recent years, declining oil prices have had a negative effect on the economy. The country is now faced with a serious trade deficit, and the government recently imposed restrictions on imports. Imports in recently years had increased markedly. The emphasis on the oil industry weakened the agricultural sector and, as a result, food imports increased. In addition, the rapid economic growth experienced during the 1970s greatly increased the demand for imported consumer goods. Venezuela has the 4th highest foreign debt in the world (US$35 billion). Despite these problems Venezuela has a relatively high per capita income (US$4,140) and living standard, compared to other countries in the region. Venezuela's total population is 14.6 million, and the population is unevenly distributed. 86% of the population lives in cities of 2500 or more. 37.4% of the population and 70% of the industry is concentrated in the Federal District which contains Caracas, and in the surrounding states of Aragua, Miranda, and Carabobo. This area constitutes only 2.36% of the country's territory. Most of the oil fields are located in the state of Zulia which also contains the country's 2nd largest city (Maracaibo). The country's coastal area contains most of the agricultural lands, and the prairies just south of the coastal mountain ranges are devoted primarily to cattle raising. The remaining 58.2% of the country's territory is essentially jungle and contains only 6.9% of the country's population. The annual population growth rate is 3.11%. Although the rate declined in recent years it is higher than in most of the other

    Full Text Available Based on LANDSAT ETM and Digital Elevation Model (DEM data derived by the Shuttle Radar Topography Mission (SRTM, 2000 of the coastal areas of Northern Venezuela were investigated in order to detect traces of earlier tsunami events. Digital image processing methods used to enhance LANDSAT ETM imageries and to produce morphometric maps (such as hillshade, slope, minimum and maximum curvature maps based on the SRTM DEM data contribute to the detection of morphologic traces that might be related to catastrophic tsunami events. These maps combined with various geodata such as seismotectonic data in a GIS environment allow the delineation of coastal regions with potential tsunami risk. The LANDSAT ETM imageries merged with digitally processed and enhanced SRTM data clearly indicate areas that might be prone by flooding in case of catastrophic tsunami events.

En la ultima década se ha extendido la distribución de A. albopictus a las Américas. En la ciudad de Tabatinga, Brasil, muy cerceide la frontera con Colombia, se ha informado la presencia de esta especie en 1996 y, posteriormente, en octubre de 1997. En marzo de 1998, en desarrollo de un e&udio sobre enfermedades tropicales realizado por el Programa de Estudio y Cotítrol de Enfermedades Tropicales, PECET, de la Universidad de Antioquia y la secretaría de Salud del Amazonas, se capturaron 8 ejemplares adultos de A. albopictus en la ciudad de Leticia, departamento del Amazonas, siendo éste el primer hallazgo de esta especie en Colombia. La presencia en Colombia de A. albopictus vuelve más complejo el problema del dengue por la mayor adaptación de este vector a climas más fríos, la capacidad de transmisión transovariana, la buena capacidad vectorial para transmitir los cuatro serotipos del virus y la mayor dificultad para su control dado que sus criaderos están en áreas peridomésticas y rurales. La distribución de esta especie tanto en zonas selváticas como rurales y urbanas presenta un peligro potencial de urbanizar la transmisión de la fiebre amarilla. Se presenta el plan de contingencia que se debe implementar por parte de la Secretaría de Salud del Amazonas con miras a evitar la propagación de este vector a otras regiones del país.

Brazil is one of 22 countries that accounts for 80% of the tuberculosis global burden. The highest incidence rates in Brazil occur in the States of Amazonas and Rio de Janeiro. The aim of this study was to describe the temporal distribution of TB in the State of Amazonas. Between 2001 and 2011, 28,198 cases of tuberculosis were reported in Amazonas, distributed among 62 municipalities, with the capital Manaus reporting the highest (68.7% concentration of cases. Tuberculosis was more prevalent among males (59.3% aged 15 to 34 years old (45.5%, whose race/color was predominantly pardo (64.7% and who had pulmonary TB (84.3%. During this period, 81 cases of multidrug-resistant TB were registered, of which the highest concentration was reported from 2008 onward (p = 0.002. The municipalities with the largest numbers of indigenous individuals affected were São Gabriel da Cachoeira (93%, Itamarati (78.1%, and Santa Isabel do Rio Negro (70.1%.

    A 4-year-old blue-fronted Amazon parrot (Amazona aestiva) was admitted for vocalization secondary to constipation. Saline infusion cloacoscopy revealed the presence of a 2-cm-diameter cloacolith within the coprodeum that was obstructing the rectal opening. The cloacolith was fragmented with a pair of biopsy forceps and the pieces removed. The cloacolith was subsequently analyzed and was composed of 100% uric acid salts. The bird improved completely and was able to defecate normally after the procedure. Cloacoliths are relative uncommon cloacal conditions, and this case documents cloacoscopic findings, rectal obstruction, and confirmation of its uric acid composition by urolith analysis.

    Osteoma is an uncommon bone formation documented in avian species and other animals. A blue-fronted Amazon parrot (Amazona aestiva) with clinical respiratory symptoms was examined because of a hard mass present on the left nostril. Radiographs suggested a bone tumor, and the mass was surgically excised. Histopathologic examination revealed features of an osteoma. To our knowledge, this is the first description of an osteoma in a blue-fronted Amazon parrot. Osteoma should be considered as a differential diagnosis in birds with respiratory distress and swelling of the nostril.

    Amazon parrots (Genus Amazona) are among the most recognizable and imperiled of all birds. Several hypotheses regarding the evolutionary history of Amazona are investigated using a combined phylogenetic analysis of DNA sequence data from six partitions including mitochondrial (COI, 12S, and 16S) and nuclear (beta-fibint7, RP40, and TROP) regions. The results demonstrate that Amazona is not monophyletic with respect to the placement of the Yellow-faced parrot (Amazona xanthops), as first implied by. In addition, the analysis corroborates previous studies suggesting a Neotropical short-tailed parrot genus as sister to Amazona. At a finer level, the phylogeny resolves the Greater Antillean endemic species as constituting a monophyletic group, including the Central American Amazona albifrons, while further revealing a paraphyletic history for the extant Amazon species of the Lesser Antilles. The reconstructed phylogeny provides further insights into the mainland sources of the Antillean Amazona, reveals areas of taxonomic uncertainty within the genus, and presents historical information that may be included in conservation priority-setting for Amazon parrots.

  7. Can Venezuela's oil sector endure Chavez' ambitions any longer?

    International Nuclear Information System (INIS)

    Honkoop, J.

    2009-07-01

    The author describes the decline of Venezuela's oil industry as well as President Chavez' reaction to Venezuela's budgetary crisis. Politicization, falling investment and the obligation to take upon itself a plethora of social spending have left national oil company Petroleos de Venezuela, S.A. unable to produce efficiently and maintain production levels. Falling oil production and lower oil prices have in turn left president Hugo Chavez unable to spread the wealth to Venezuela's poor and he is searching desperately for ways to extract yet more from Venezuela's dysfunctional economy. As funds run out, Venezuela's expensive foreign policy, supporting regional allies, in particular Cuba, and seeking to export anywhere but the United States, proves overly expensive. Venezuela's impoverished masses, still supportive of Chavez during February's elections, may become less so as funds for social programmes run out. For Chavez it is a time for making choices... otherwise the people of Venezuela will choose for him. [nl

On one extreme, there is Mundurukú do Pará, the language of daily communication in the Mundurukú Indigenous Land, with fluent speakers found across all generations and still acquired by children as a mother tongue. On the other extreme, there is Mundurukú do Amazonas, formerly spoken in the Kwatá-Laranjal Indigenous Land, but whose inhabitants have shifted to Portuguese. A group of Mundurukú students from Amazonas decided to initiate a process of language revitalisation as a way to strengthen the community's ethnic and cultural identity. This paper reports the initial stages of language planning, and includes future actions to promote language use in the homes and communities, assessement of language proficiency, and definition of educational programs to teach Mundurukú in local schools.Mundurukú, uma língua Tupí do Brasil, apresenta dois cenários opostos.

    A 37-year-old yellow-crowned Amazon parrot (Amazona ochrocephala) and a 20-year-old red-lored Amazon parrot (Amazona autumnalis) each presented with a large mass localized on the lateral neck. With the first bird, there was no evidence of signs of pain or discomfort, and the bird prehended and swallowed food normally. The second bird showed signs of mild upper-gastrointestinal discomfort. Results of an ultrasound examination and aspiration of the mass on each bird revealed a cystic structure. A computed tomography performed on the second bird revealed a large polycystic mass connected to the pharynx by a lateral tract. During surgical resection, both masses were found to originate from the subpharyngeal area. Based on topography and the histopathologic and immunohistochemical results, the masses were determined to be a second branchial cleft cyst for the first case and a second branchial pouch cyst for the second case. In addition, a carcinoma was present in situ within the epithelium of case 1, and the cyst in case 2 was secondarily infected. Branchial cysts are uncommonly diagnosed in veterinary and human medicine. These 2 cases are the first documented in parrots and appear similar to second branchial cysts reported in adult humans.

    Full Text Available Fluorescent (acridine orange microscopical examination of capillary centrifuged blood (quantitative buffy coat [QBC®] analysis and Giemsa stained thick blood smears (GTS were compared for diagnosis of malaria in blood specimens from adults living in malaria transmission areas of the States of Bolivar and Amazonas in southeastern and south Venezuela, respectively. Of a total of 198 GTS examined, 95 subjects (48% showed parasitaemia. Among the 95 blood films with a positive GTS, 94 were judged positive by the QBC. However, positive QBC tubes were found in 29 out of 103 blood specimens with a negative GTS. Thus, relative to a GTS standard, the sensitivity and specificity of the QBC-test was 99.2% and 72%, respectively. Young trophozoites of Plasmodium vivax and P. falciparum could not be distinguished with certainty. It is confirmed that the QBC offers many advantages compared with the standard diagnosis of malaria parasites, specifically in the speed of staining and ease of interpretation. However, in places where P. falciparum and P. vivax occur, species and stage differentiation should be confirmed with the GTS.

    2007-12-01

    The decorative panels in the foyer of the Teatro Amazonas, inaugurated in 1896, stand out from the rest of the building's ornamental iconography. The rubber trade brought great wealth to the capitals of Pará and Amazonas and as these cities gained national and international fame, their urban fabric and forms of sociability underwent significant changes. The article looks for parallels between the landscape representations of Amazonian nature adorning the building's foyer, the construction of the modern city, and social uses of the Teatro Amazonas, symbol of the era and emblem of the newly rich elite, who were then taking their place on the regional and national stages. The Teatro Amazonas formed the center of the era's social life and its foyer played host to veritable rituals of 'civilization', in which Brazilian and foreign guests enjoyed the fine setting of Amazon's nature as represented in the decorative wall panels.

    2014-09-01

    The lipoprotein panel is a useful diagnostic tool that allows clinicians to evaluate blood lipoprotein fractions. It is a standard diagnostic test in human medicine but is poorly understood in avian medicine. Amazon parrots (Amazona species) are popular pets that frequently lead a sedentary lifestyle and are customarily fed high-fat diets. Similar to people with comparable diets and lifestyles, Amazon parrots are prone to obesity and atherosclerosis. In human medicine, these conditions are typically correlated with abnormalities in the lipoprotein panel. To establish reference intervals for the lipoprotein panel in Amazon parrots, plasma samples from 31 captive Amazon parrots were analyzed for concentrations of cholesterol, triglycerides, high-density lipoprotein (HDL), low-density lipoprotein (LDL), and very low-density lipoprotein (VLDL). The data were also grouped according to sex, diet, body condition score, and age. Aside from HDL levels, which were significantly different between male and female parrots, no intergroup differences were found for any of the lipoprotein fractions.

Pesquisa qualitativa, descritivo-analítica, cujos dados foram coletados através de entrevistas, revisão de documentos e de páginas de internet, tomando como conceito guia a regionalização em saúde. Os achados do estudo mostram uma cena social onde predominam a assimetria, a verticalidade, a competitividade e a fragilidade das relações multilaterais entre municípios, associados a um perfil cartorial das instituições que atuam na região de saúde sob estudo. Os agentes políticos envolvidos no processo têm limitado reconhecimento das condições sociopolíticas e institucionais em que atuam. Tendem a atribuir os problemas de gestão e operacionalização das redes de assistência à configuração dos espaços naturais-geográficos amazônicos, mas seu financiamento, governança e capacidade técnica são insuficientes para superá-los.

    Full Text Available Os aspectos físicos, operacionais e econômicos da frota pesqueira no município de Coari, situado na região do Médio Rio Solimões (Estado do Amazonas, foram analisados por meio de dados coletados diretamente no porto de desembarque e dados secundários no período de setembro de 2008 a outubro de 2009 obtidos junto às entidades de classe ligadas à atividade pesqueira. A frota pesqueira do município de Coari foi composta, em sua maioria, por canoas motorizadas (7,6 m ±1,29, e por barcos pesqueiros com média de comprimento de 12,8 m (±1,94. Os lagos Coari e Juçara foram os principais locais de captura do pescado. A malhadeira foi o apetrecho de pesca mais utilizado durante as expedições. As principais espécies capturadas foram as da ordem Characiforme, jaraqui (Semaprochilodus spp., pacu (Mylossoma duriventre, Myleus sp., sardinha (Triportheus spp. e curimatã (Prochilodus nigricans. O componente dos custos mais oneroso durante as pescarias de canoas motorizadas foi o combustível. Estes resultados podem subsidiar a elaboração de políticas de investimento e medidas adequadas de manejo para melhoria da atividade pesqueira na região de Coari.

    Full Text Available A violência contra crianças e adolescentes é um fenômeno frequente, mas pouco se conhece sobre o contexto em que ocorre e sobre suas consequências. O objetivo deste estudo é caracterizar esta violência no Interior do Estado do Amazonas. Foram analisados 193 registros do Relatório Txain sobre a Violência contra Crianças e Adolescentes. Como resultado, verificou-se que grande parte dos registros oficiais omitem informações. A agressão física é o tipo de violência mais relatado, e a maior parte das vítimas é constituída de adolescentes do sexo feminino de idades entre 12 e 15 anos. Os agressores são predominantemente desconhecidos das vítimas e são do sexo masculino. Em termos de consequências para a saúde, há referência a algumas lesões físicas, mas os dados são bastante omissos em relação à saúde mental. Estes dados sugerem a necessidade de integralização e aprimoramento dos sistemas de registro, informação e atendimento a vítimas fora das grandes cidades.

    Full Text Available La revisión de algunos supuestos que conforman el modelo liberal de sociedad, se trazan como inicio para inferir características presentes en el proceso de descentralización dentro de las reformas del Estado en el contexto venezolano. En las dos últimas décadas importantes cuestionamientos se realizan acerca de la estructura centralizada del Estado en América Latina y de los desiguales niveles de desarrollo que se hallan dentro de un mismo territorio nacional, asociándose el centralismo con la dinámica de la actividad económica capitalista. En la relación de estas variables político-económicas, se describen obstáculos para el desarrollo y agotamiento de las capacidades funcionales del Estado, surgiendo como alternativa la descentralización. Una definición que integra la descentralización política, administrativa y económica, según se dirija a incidir en la participación política, en la administración estatal o en el modelo económico, abre cauces para la discusión del modelo liberal de sociedad. ¿Puede señalarse que la conducción del proceso de descentralización en Venezuela ha seguido orientaciones liberales, con tan marcado predominio económico que ha afectado la institucionalidad política que el mismo proceso conlleva? La descentralización en Venezuela, orientada hacia el fortalecimiento político institucional, tomó el camino de las reformas neo-liberistas, lo cual se le ha convertido en freno para continuar avanzando hacia el fortalecimiento de la institucionalidad política democrática.

    2001-06-01

    Full Text Available The waterfalls of the Presidente Figueiredo municipality represent a fascinating natural scenery of northeast state of Amazonas, northern Brazil. The falls, generally less than 10m high, are developed on siliciclastic rocks of the Nhamundá (Lower Silurian, and Manacapuru (Upper Silurian - Lower Devonian formations. Morphological and structural analyses of these features indicate that most of them originated through Quaternary neotectonics and are installed in NE-trending normal fault escarpments. Waterfalls also developed within pseudokarstic features, but are less frequent. The origin of the Presidente Figueiredo waterfalls probably goes back to the Neogene, when the region was submitted to laterization processes associated with a humid climate and a dense rainforest. These conditions favored the development of caves in quartzarenites of the Nhamundá Formation. During the Quaternary, the region was subjected to NE-trending normal faulting which displaced laterite layers, rivers and streams giving rise to waterfalls. These climatic and tectonic phenomena promoted intense relief dissection, as indicated by fault escarpment retreat and cave dismantlement, responsible for the present-day morphologic configuration.As cachoeiras da região de Presidente Figueiredo constituem um dos mais fascinantes cenários naturais do nordeste do Estado do Amazonas, norte do Brasil.

    Full Text Available La estrategia de la descentralización del Estado se inicia con la aprobación de la Ley de Descentralización, Delimitación y Transferencia de Competencias del Poder Público (LOD en diciembre de 1989. El propósito de la descentralización es aumentar la capacidad de respuesta eficiente del sistema de servicios a los problemas de salud a la población entre los diferentes niveles de poder central, estadal y municipal, así como brindarle una mayor participación a las comunidades en su solución. En Venezuela las instituciones que prestan servicios de salud son numerosas, en su mayoría independientes y ausentes de una coordinación efectiva por parte del Ministerio de Sanidad y Asistencia Social (MSAS, ente creado en 1936 con mayor injerencia en los asuntos relativos a la salud. El MSAS se orienta hacia una política de centralización normativa – procedimental y desconcentración programática que consiste en la transferencia de las funciones administrativas, requeridas para el desarrollo de los programas, a los órganos regionales del Sistema Nacional de Salud. Destaca que el MSAS delimitará a las comunidades territorial, demográfica y técnicamente, en función del establecimiento de atención integral a la salud que le preste sus servicios. Este trabajo tiene como objetivo evaluar el proceso de descentralización de la salud, tomando en cuenta la actual coyuntura sociopolítica y económica en el marco de la nueva Constitución Bolivariana (1999. La muestra está constituida por los Estados Monagas, Carabobo, Aragua, Falcón y Zulia. Los resultados se concretan en el aumento de la productividad y calidad de los servicios de atención médica; simplificación de los procesos administrativos y el fortalecimiento de la democracia, al contar con una comunidad involucrada y satisfecha con el servicio de salud. Se concluye que el proceso de descentralización municipal ha sido frenado por el Gobierno central en los Estados Monagas y

    Full Text Available To assemble Volkswagen cars for the Venezuela market, a large hall has been built, which is fitted with full facilities for its purpose, such as painting and greasing installations, and large parking area for the finished vehicles. The siting of this hall was carefully studied, and such factors as nearness to industrial zones, climate, and ease of access were decisive aspects that were taken into account. The final choice was a site near Morón, in the Carabobo Department, close to the sea. The main constructional item is the roof of the large hall. It is made of a series of hyperbolic-parabolic reinforced concrete thin shells, of rectangular planform, and slightly inclined towards the north, to produce a saw edge profile. Each of these shells is supported by a central column. The hollow spaces along the saw edge profile have been used for ventilation. The enclosing walls consist of trellice material, which also provide ample facility for additional ventilation.Para el montaje de los coches Volkswagen destinados al mercado venezolano, se ha construido una gran nave dotada de todos los servicios necesarios: pintura, engrases, aparcamiento de los vehículos terminados, etc. La elección del lugar más apropiado para la situación de la nave y edificios anexos fue motivo de un detenido estudio, en el que la proximidad a zonas industriales, clima, fácil entrada de materiales procedentes de ultramar y salida para los acabados, fueron los factores decisivos. Definitivamente se eligió un solar en las cercanías de Morón, del departamento de Carabobo, y próximo al mar. Lo más notable es la cubierta de la gran nave, formada por una serie de láminas parabólico-hiperbólicas de hormigón armado, de planta rectangular, inclinadas ligeramente hacia el norte para formar un perfil en diente de sierra. Cada una de estas láminas se soporta por un montante central. Los huecos que dichos dientes de sierra dejan se han aprovechado para la ventilación. Los

    Venezuela has pioneered a preventive-focused and comprehensive movement for Occupational Safety and Health (OSH) in Latin America. However, despite being an oil-rich country, it has some of the lowest salaries for their workers and highest levels of hyperinflation, devaluation, crime, and violence of the world. Review the current status and challenges on relevant aspects of OSH in Venezuela. Review of literature and documents from national governments, UN agencies, NGOs, and the Venezuelan government concerning OSH and related topics since 1986. Reformed in 2005, the Organic Law on Prevention, Conditions and Environment (LOPCYMAT) was a fundamental moment of change for OSH. Factors which have impacted OSH the strongest are (i) the creation of the National Institute of Occupational Safety and Health (INPSASEL) and (ii) the socioeconomic crisis Venezuela is going through. Venezuela's laws are innovative and yet non-compliance is enormous. Almost half of the population works in the informal sector. Following the International Labor Office projections, 5 people die per day in Venezuela due to occupational accidents or diseases, making health and safety at work a luxury rather than a right. The quality of life for the average worker has deteriorated, affecting not only health but the overall well-being of all Venezuelans. The political and socio-economic situation has led to a mass exodus of more than 1.6 million highly qualified and talented professionals. Many statistics concerning OSH are not updated and are unreliable regarding occupational accidents and diseases. There is a substantial difference between what is written to protect individual Venezuelans in the workplace and the reality of workplace conditions. Substantial governmental actions are needed in the immediate future to improve occupational safety and health of Venezuelan workers. Copyright © 2015 The Author. Published by Elsevier Inc.

Se encuentra que la línea editorial de este diario a finales del trienio 1945-1948 demuestra una fuerte oposición de la jerarquía eclesiástica del Zulia al gobierno del trienio acciondemocratista, al cual trató de desprestigiar con la difusión de un discurso negativo acerca de la acción del gobierno en los ámbitos social, moral y educativo, fundamentado en una concepción del partido de gobierno como un brazo del comunismo internacional. Una vez consumado el derrocamiento del presidente Rómulo Gallegos, los editores del diario "La Columna" difunden un discurso legitimador del Golpe de Estado del 24 de Noviembre, asociando al derrocado gobierno con el caos, la inmoralidad, la corrupción y la incapacidad para gobernar, y a las Fuerzas Armadas con el retorno de la moral, con la paz, la seguridad y el bienestar de la familia venezolana.

Este município de população predominantemente indígena constitui uma importante noso-área da Amazônia para o problema da tuberculose, cuja magnitude se expressa por intermédio do coeficiente 2,4 vezes mais elevado que a média estadual e até quatro vezes mais que a média nacional. Análises estatísticas utilizadas para avaliar a tendência em relação à associação com a idade, o sexo e a forma clínica revelaram diferenças no comportamento da endemia, quando comparados os coeficientes de incidência entre os casos de procedência urbana e rural. As taxas padronizadas mostraram a população masculina com uma incidência mais elevada que a feminina nas duas áreas de residência. A faixa etária mais atingida foi acima de 50 anos, porém a proporção de menores de 15 anos se mostrou acima dos valores esperados na população geral do país, além de apresentar diferentes níveis de gravidade nas subáreas rurais estudadas. Os achados indicam que esta situação pode ser explicada pelas desigualdades, sobretudo, relativas à acessibilidade aos serviços de saúde que, contraditoriamente, parecem menos resolutivos na área urbana.This study describes the tuberculosis situation in São Gabriel da Cachoeira, Amazonas State, Brazil, from 1997 to 2002.

    Despite the availability of tuberculosis prevention and control services throughout Amazonas, high rates of morbidity and mortality from tuberculosis remain in the region. Knowledge of the social determinants of tuberculosis in Amazonas is important for the establishment of public policies and the planning of effective preventive and control measures for the disease. To analyze the relationship of the spatial distribution of the incidence of tuberculosis in municipalities and regions of Amazonas to the socioeconomic factors and indigenous tuberculosis component, from 2007 to 2013. An ecological study was conducted based on secondary data from the epidemiological surveillance of tuberculosis. A linear regression model was used to analyze the relationship of the annual incidence of tuberculosis to the socioeconomic factors, performance indicators of health services, and indigenous tuberculosis component. The distribution of the incidence of tuberculosis in the municipalities of Amazonas was positively associated with the Gini index and the population attributable fraction of tuberculosis in the indigenous peoples, but negatively associated with the proportion of the poor and the unemployment rate. The spatial distribution of tuberculosis in the different regions of Amazonas was heterogeneous and closely related with the socioeconomic factors and indigenous component of tuberculosis.

    National oil companies were key elements in the initial OPEC strategy and they brought a de-integration of oil industry. These companies have tried to move from crude marketing to product marketing through new investments at home and abroad in order to get higher value added and more secure markets for crude. Low prices bring new challenges. Venezuela's answers are strategic associations, operating contract for marginal fields and profit sharing agreements. (Author)

The author has revealed the interaction of internal political processes in Venezuela as the country's leader in the region, with its integration policy, and also identified trends in the further development of energy policy and strategy of Latin American countries. The research of energy resources of Latin America determined that the main factor that works in favor of convergence states within the South American "geopolitical ring" is to ensure energy security. Venezuela is among the richest resources of Latin America. In the research it was determined that Petrosur, Petrocaribe and Petroandina provide the basis for a range of bilateral agreements to promote cooperation, creation ventures based on the state oil companies of these states.

  17. Violence in Venezuela: oil rent and political crisis Violência na Venezuela: renda petroleira e crise política

    Full Text Available This article analyzes the changes in violence in Venezuela during the last forty years. It links the ups and downs of the oil revenues and the political crisis of the country to the changes in the homicide rates, which increased from 7 per 100 thousand inhabitants in 1970 to 12 in 1990, 19 in 1998 and 50 in 2003. The article characterizes Venezuela as a rentist society and shows its trajectory from rural violence to the beginning of urban violence, the guerilla movements of the 60s, the delinquent violence related to the abundance of oil revenues and the violence during the popular revolt and the sackings of 1989 in Caracas. After this, we analyze the coups d'état of 1992 and the influence the political violence exerted upon criminal violence. We describe the political and party changes in the country, their influence upon the stabilization of homicide rates since the mid-90s and their remarkable increase during the H. Chávez government. The article finishes with an analysis of the current situation, the official prohibition to publish statistics on homicides and with some thoughts about the perspective of greater violence in Venezuela.O presente artigo analisa as mudanças na violência ocorridas na Venezuela nos últimos quarenta anos, relacionadas com os altos e baixos da renda petroleira e com a crise política no país, fatos que contribuíram para um aumento nas taxas de homicídios: de 7 por cada cem mil habitantes em 1970 a 12 em 1990, 19 em 1998 e 50 no ano de 2003. O artigo caracteriza a Venezuela como sociedade rentista e, a partir daí, faz uma retrospecção cobrindo desde a violência rural até os inícios da violência urbana, o movimento guerrilheiro dos anos sessenta, a criminalidade resultando da abundância dos recursos petroleiros e a violência em decorrência da revolta popular e dos saques ocorridos em 1989 em Caracas. Em seguida são analisados os golpes de Estado de 1992 e o impacto que a violência política exerceu

    Naturally occurring radionuclides, such as the uranium and thorium decay chains, are present in rocks and soils. But its distribution is not homogeneous: it depends on the type of rock being that those of volcanic origin have higher concentrations of uranium and thorium. These are NORM. Locations with NORM present higher dose rates than the world average. Thus, the determination of the natural radioactivity of a NORM region is of extreme importance since it provides data for the estimation of human exposure to natural radiation. In addition, if there is a mining company exploring NORM, the background radiation estimation should be considered in the decommissioning and future planning. There are places in Brazil, such as Granito Madeira in the state of Amazonas, in the north of Brazil, where NORM is present. It is an extremely remote area located within the Amazon Forest currently in the process of open cast mining. In this study, the iodide scintillator detector was used to measure and map the natural background radiation of the Granito Madeira using a scintillator detector of sodium iodide that was transported in tracks within the forest. The data obtained were georeferenced, classified and used to obtain the annual dose related to gamma radiation. The results are presented in frequency histograms and maps. The annual average was (6.0 ± 3.0) mSv.y{sup -1}. These data were compared to those available from other regions with NORM in Brazil and the 2010 UNSCEAR report. (author)

    The objective of this study was to evaluate the protein requirements for hand-rearing Blue-fronted Amazon parrots (Amazona aestiva). Forty hatchlings were fed semi-purified diets containing one of four (as-fed basis) protein levels: 13%, 18%, 23% and 28%. The experiment was carried out in a randomized block design with the initial weight of the nestling as the blocking factor and 10 parrots per protein level. Regression analysis was used to determine relationships between protein level and biometric measurements. The data indicated that 13% crude protein supported nestling growth with 18% being the minimum tested level required for maximum development. The optimal protein concentration for maximum weight gain was 24.4% (p = 0.08; r(2) = 0.25), tail length 23.7% (p = 0.09; r(2) = 0.19), wing length 23.0% (p = 0.07; r(2) = 0.17), tarsus length 21.3% (p = 0.06; r(2) = 0.10) and tarsus width 21.4% (p = 0.07; r(2) = 0.09). Tarsus measurements were larger in males (p < 0.05), indicating that sex must be considered when studying developing psittacines. These results were obtained using a highly digestible protein and a diet with moderate metabolizable energy levels.

    2015-01-01

    This paper reports the behavior of the dissolved U-isotopes 238 U and 234 U in groundwater providing from 15 cities in Amazonas State, Brazil. The isotope dilution technique accompanied by alpha spectrometry were utilized for acquiring the U content and 234 U/ 238 U activity ratio (AR) data, 0.01–1.4 µg L −1 and 1.0–3.5, respectively. These results suggest that the water is circulating in a reducing environment and leaching strata containing minerals with low uranium concentration. A tendency to increasing ARs values following the groundwater flow direction is identified in Manaus city. The AR also increases according to the SW–NE directions: Uarini→Tefé; Manacapuru→Manaus; Presidente Figueiredo→São Sebastião do Uatumã; and Boa Vista do Ramos→Parintins. Such trends are possibly related to several factors, among them the increasing acid character of the waters. The waters analyzed are used for human consumption and the highest dissolved U content is much lower than the maximum established by the World Health Organization. Therefore, in view of this radiological parameter they can be used for drinking purposes. - Highlights: • U-isotopes data in important aquifer systems in Amazon area. • Application of the U-isotopes data to investigate the groundwater flow direction. • Evaluation of the drinking-water quality in terms of dissolved uranium

    A clinically normal 2-year-old Hispaniolan Amazon parrot (Amazona ventralis) was found to have periodic second-degree atrioventricular (AV) block with variable nodal conductions while anesthetized with isoflurane during a thermal-support research project. Arrhythmias were observed on 5 successive weekly electrocardiograms. A complete cardiac evaluation, including a diagnostic electrocardiogram, revealed intermittent bradyarrhythmias ranging from a 2:1 to a 7:1 second-degree AV block, with concurrent hypotensive episodes during the nodal blocks. Results of a complete blood cell count, plasma biochemical profile, blood gas analysis, and atropine-response test, as well as radiography and auscultation, revealed no obvious cause for the arrhythmias. Echocardiography demonstrated cardiac wall thickness, chamber size, and systolic function similar to other psittacine birds. On return to the colony, the parrot continued to be outwardly asymptomatic despite the dramatic conduction disturbances. Although cardiac arrhythmias, including second-degree AV block, have been widely reported in birds, the wide variation of nodal conductions, the intermittent nature, and an arrhythmia with a 7:1 second-degree AV block that spontaneously reverts to normal as seen in this case have not been well documented in parrots.

  3. Multifragment alleles in DNA fingerprints of the parrot, Amazona ventralis

    Human DNA probes that identify variable numbers of tandem repeat loci are being used to generate DNA fingerprints in many animal and plant species. In most species the majority of the sc rable autoradiographic bands of the DNA fingerprint represent alleles from numerous unlinked loci. This study was initiated to use DNA fingerprints to determine the amount of band-sharing among captive Hispaniolan parrots (Amazona ventralis) with known genetic relationships. This would form the data base to examine DNA fingerprints of the closely related and endangered Puerto Rican parrot (A. vittata) and to estimate the degree of inbreeding in the relic population. We found by segregation analysis of the bands scored in the DNA fingerprints of the Hispaniolan parrots that there may be as few as two to five loci identified by the human 33.15 probe. Furthermore, at one locus we identified seven alleles, one of which is represented by as many as 19 cosegregating bands. It is unknown how common multiband alleles might be in natural populations, and their existence will cause problems in the assessment of relatedness by band-sharing analysis. We believe, therefore, that a pedigree analysis should be included in all DNA fingerprinting studies, where possible, in order to estimate the number of loci identified by a minisatellite DNA probe and to examine the nature of their alleles.

    Retrobulbar neoplasms are not common in mammals and are even more infrequently seen in nonmammalian species. The current report describes a retrobulbar mass creating exophthalmia and neurologic signs in a red-lored Amazon parrot (Amazona autumnalis). A 27-year-old female parrot presented for a 3-day history of anorexia and a 2-week history of periocular soft tissue swelling and exophthalmia of the right eye. Physical examination revealed 9% dehydration and right eye exophthalmia with inability to retropulse the globe. A fine-needle aspirate was performed, and cytologic evaluation revealed necrotic debris with scattered clusters of epithelial cells, moderate numbers of macrophages, and few heterophils. Given the possibility of neoplasia and paucity of treatment options, the owners elected euthanasia and submitted the body for necropsy. A large, fluctuant, friable, red, retrobulbar mass with multiple areas of hemorrhage, on cut surface, was noted at necropsy. Histologically, the mass was composed of neoplastic, cuboidal to columnar epithelial cells, forming rosette-like glandular structures, admixed with abundant necrotic debris. The neoplastic cells were strongly positive for cytokeratin (AE1/AE3) by immunohistochemistry. Based on histopathology and immunohistochemistry, the mass was diagnosed as an adenocarcinoma.

    Full Text Available Las plantaciones de caña de azúcar se dieron en América Latina y en las islas antillanas como consecuencia de la demanda en los mercados europeos desde el XVI hasta el XIX. El escenario construido con financiamiento internacional y la participación activa de Holanda, Francia, Inglaterra, Estados Unidos, incluso Portugal y España, implicó la inversión de grandes capitales en las colonias para la instalación de los ingenios y la importación de la mano de obra. En el caso de Venezuela y en particular de la región sucrense, la producción y el comercio del azúcar y sus derivados marcó una singular diferencia con lo acontecido en otros países; por cuanto la metrópoli no invirtió capitales para la explotación a gran escala de este cultivo agrícola que tomó fuerza en este escenario, a partir del siglo XIX. En el distrito Sucre del estado Zulia el proceso económico generado por los cambios en la explotación tradicional de la caña de azúcar, en las primeras décadas del siglo XX, aceleró la industrialización del azúcar y sus derivados, cuya referencia más significativa fueron las nuevas compañías azucareras que le dieron un impulso a una clase dominante que diversificó la economía nacional y expandió el desarrollo del capitalismo en Venezuela.

    Full Text Available Resumo: A crescente demanda de mercado por produtos florestais não madeireiros oferece uma oportunidade de desenvolvimento econômico que poderia aliar a inclusão social produtiva de agricultores familiares com a conservação dos ecossistemas florestais. No entanto, o aumento da produção poderá significar a substituição do manejo extrativo das florestas pelo monocultivo, anulando seus efeitos positivos quanto à conservação das florestas. Buscou-se identificar os fatores determinantes que levam os agricultores familiares tradicionais do baixo rio Manacapuru a se engajarem na atividade extrativista ou de cultivo do açaí-da-mata (Euterpe precatória, a espécie nativa do estado do Amazonas. Dado que a coleta extrativa dos frutos é feita mediante a escala das árvores, a decisão de produção parece depender principalmente da oferta de mão de obra masculina jovem, de trabalhadores com a habilidade e força física para realizar essa tarefa. Já a decisão de cultivo pode estar associada à maior disponibilidade de capital financeiro que as famílias obtêm da renda das atividades agrícolas. As famílias que cultivam o açaí mantiveram a prática de coleta extrativa, indicando que o plantio de pequenas áreas de cultivos consorciados representa uma estratégia de aumento da produção sem que necessariamente haja a completa substituição do extrativismo pelo cultivo da espécie.

    Figures of Colombian immigrants in Venezuela in the period 1981-1986 as well as the development of their socio-demographic profile and their integration into the labor market are analyzed by means of ad hoc tables drawn from a Sample Home Survey by the Oficina Central de Estadisticas e Informatica and information from the civil record office. It is estimated that in 1987 there are only half a million Colombians in Venezuela and, contrary to what is generally assumed, not only has the afflux decreased (3/4 of the Colombians entered before 1981), but also a return migration can be observed. Colombian immigration is not homogeneous, but is made up of different groups as far as their professional skills and occupations are concerned. The number of Colombians engaged in household service and those living in rural areas has decreased, but not the number of active farm workers. A greater proportion of Colombians engaged in trade and sales activities is observed, but artisans and skilled labor are still the majority.

    Current health conditions of Venezuela, together with the tropical proliferation of different types of Aedes (aegypti and albopictus), suggest the arrival to this country of ZIKA virus (ZIKV). The Pan American Health Organization urges Latin American countries to take measures to prevent the ZIKV entry and advises that these measures must be designed to detect the introduction of ZIKV in an area, track its spread and actively monitor the disease. In Venezuela and other Latin-American countries, where endemicity is high for other arboviruses such as dengue arid chikungunya, health authorities should strengthen their surveillance systems to detect early and timely introduction of ZIKV ap.d refine diagnostic methods to confirm the infection rate; however, the high incidence of cases due those viral agents reflects weakened and poorly timed insensitive monitoring systems, as well as, poor vector control measures, arising the questions: will this arbovirus pop in our country, will it set as the other as edemicepidemic and lead to alter their clinical behavior and severity of the disease?

    Briceño-León, Roberto

    2012-12-01

    Venezuela was considered one of the least violent countries in Latin America, however by 2010 it was among the countries with the highest homicide rate. This article analyzes the evolution of homicides in Venezuela between 1985 and 2010 and proposes the existence of three stages which correspond to trends in social and political institutions of the country. The first from 1985 to 1993, characterized by the looting of 1989 and the coups d'état of 1992, when for the first time the homicide rate rose from 8 to 20. The second phase from 1994 to 1998 was a recovery period of the institutional and political stability when the homicide rate remained constant at around 20. The third phase began in 1999 with the H Chavez government and the institutional destruction that comes with the Bolivarian revolution and caused an increase in the rate of 20 to 57 homicides per 100 thousand inhabitants. This article argues that the explanation for the changes in the phases is to be found in the transformation of social and political institutions.

A continuación presentamos los resultados para el caso venezolano, manteniendo como hipótesis que el desarrollo ferroviario en ese país estuvo más determinado que en el resto de América Latina por las necesidades de la construcción del Estado y de integración de la economía nacional en el mercado mundial como productora primario-exportadora. Tal fue la dependencia que aquél tuvo de estos elementos, que tras la finalización del ciclo alcista primario- exportador en las décadas de 1920-30, la explotación ferroviaria sufrió una crisis cuya solución fue el cierre de las líneas.

En algunos países latinoamericanos como Colombia, Chile, Argentina, Brasil, Costa Rica se han impulado procesos de descentralización con el fin de racionalizar la actividad estatal y, precisamente, contribuir a la gobernabilidad.En Venezuela la Comisión para la Reforma del Estado (COPRE implementó la descentralización en 1988 como una forma de superar el modelo estado céntrico, caracterísitico de las últimas décadas en el país. El proceso no estuvo acompañado por cambios constitucionales, lo que condujo a conflictos entre diversas normas y al consiguiente retraso en la implementación de las nuevas políticas. El ejercicio descentralizador se está desarrollando principalmente a nivel político, por ejemplo, en los municipios de Chacao, Baruta, El Hatillo y Libertador, que pertenecen al Area Metropolitana Interna de Caracas. Así, el proceso descentralizador se vive con diferencias marcadas resultantes del tipo de administración implementada desde la alcaldía, la mayor o menor disponibilidad de resursos económicos y humanos, la población y la pobreza.ABSTRACT: Decentralization is one of the mechanisms by which the central State transfers political and administrative competences to the localities, sometimes with the purpose of strenghtening political participation, to achieve state efficiency of to look for gobernability.

Con base en el pensamiento filosófico sobre las libertades se analizan los antecedentes de la Asamblea Nacional Constituyente de 1999 y los principios losócos, sociales e históricos que determinaron la “Democracia participativa y protagónica” y “Estado social de derecho y justicia” presentes en la Constitución, que bajo la premisa de derechos, la libertad, la igualdad, la propiedad, la seguridad y la justicia, permite a todos los ciudadanos, en teoría, el goce de los derechos y libertades. La Constitución vigente dene al sistema democrático como “Estado social de derecho y Justicia”, el cual supone como fundamento la igualdad entre los ciudadanos para ejercer sus deberes y derechos políticos. Del análisis de los elementos que integran la democracia participativa y de los derechos se concluye el advenimiento postconstitucional de un estado paralelo denominado “estado comunal” tras la promulgación de leyes orientadas a sectorizar la participación ciudadana bajo la ideología del sector ocial y el desconocimiento de los derechos humanos ante las sentencias emitidas por la Corte Interamericana de los Derechos Humanos

    Full Text Available The Republic of Venezuela was an oasis in Latin America, a stable, democratic and prosperous country for several decades until the coming of the 1980s’ crisis. The new context and the erosion of traditional actors forced profound political changes. The crisis, the adjustments made during the 1990s and the population’s hopes of one day returning to the path of prosperity generated increasingly radical policy responses. This article seeks to analyse the political responses of the Venezuelan people to the challenges posed by their new socioeconomic reality and how these connect with visions derived from past experience and the approach to the roles of state and leader. It also explores the frustration caused by failure to meet their expectations, leading to the election of increasingly radical options.

This work assess the environmental impact caused by visual pollution in public spaces, using as a case of study a mixed-use neighborhood in San Cristobal, the capital of Tachira state, Venezuela. Such assessment was made using a qualitative approach, where special emphasis was paid to the perception of these impacts by a purposive sample of users of this area. The compilation and analysis of information reveal the main visual pollutants existing in these public spaces where, in addition to outdoor advertising, overhead wires, rubbish, graffiti, vacant land, among others, cars and outdoor kiosks. Neighborhood users are sensitive to the presence of visual pollutants, which affects them physically and psychologically, as well as for the visual quality of their environment. Such signs were used to guide a qualitative appraisal of environmental impacts generated by these circumstances and to propose policies to mitigate them.

    Full Text Available ABSTRACT The fauna of blowflies (Calliphoridae and Mesembrinellidae in three localities of primary Amazon forest coverage in the Amazonas-Negro interfluvial region was assessed. A total of 5066 blowflies were collected, with Chloroprocta idiodea being the most abundant species (66.3%. A difference in species richness between the localities ZF2 and Novo Airão was observed. Comparison among sampled sites revealed no considerable variation in fauna composition, except for the species Eumesembrinella benoisti (Séguy 1925 and Hemilucilia sp., whose occurrence was observed only in a single locality. Apparently, Amazon rivers are not efficient geographical barriers to influence the current composition of necrophagous blowfly assemblages. Also, most of the blowfly species did not show a noticeable specificity for any specific forest among the interfluvial areas of the ombrophilous forest. Finally, an updated checklist of necrophagous blowfly species of the Amazonas state in Brazil is presented.

    In the State of Amazonas, Brazil, urban expansion together with precarious basic sanitation conditions and human settlement on river banks has contributed to the persistence of waterborne and intestinal parasitic diseases. Time series of the recorded cases of cholera, typhoid fever, hepatitis A and leptospirosis are described, using data from different levels of the surveillance systems. The sources for intestinal parasitosis prevalence data (non-compulsory reporting in Brazil) were Medical Literature Analysis and Retrieval System Online (MEDLINE), Literatura Latino-Americana (LILACS) and the annals of major scientific meetings. Relevant papers and abstracts in all languages were accessed by two independent reviewers. The references cited by each relevant paper were scrutinized to locate additional papers. Despite its initial dissemination across the entire State of Amazonas, cholera was controlled in 1998. The magnitude of typhoid fever has decreased; however, a pattern characterized by eventual outbreaks still remains. Leptospirosis is an increasing cause of concern in association with the annual floods. The overall prevalence of intestinal parasites is high regardless of the municipality and the characteristics of areas and populations. The incidence of hepatitis A has decreased over the past decade. A comparison of older and recent surveys shows that the prevalence of intestinal parasitic diseases has remained constant. The load of waterborne and intestinal parasitic diseases ranks high among the health problems present in the State of Amazonas. Interventions aiming at basic sanitation and vaccination for hepatitis A were formulated and implemented, but assessment of their effectiveness in the targeted populations is still needed.

El régimen ha sido descrito de muchas formas: democracia participativa, híbrido, mixto, personalista, populista, iliberal, autoritarismo competitivo. El objetivo de este trabajo es determinar el nivel de calidad de la democracia en Venezuela, en el marco de una concepción procedimental de la democracia. La evaluación empírica de cinco dimensiones de calidad de la democracia (decisión electoral, participación, respuesta a la voluntad popular, rendición de cuentas y soberanía revela un nivel bajo en conjunto, con escasa variación entre 2005 y 2010. Los escenarios posibles luego de las elecciones de 2012 incluyen: reforzamiento de las tendencias autoritarias, militarización abierta, liberalización política con fortalecimiento institucional, o volatilidad duradera con conflicto polarizado y debilidad institucional. La salud del presidente Chávez afectará estos escenarios, dado su carácter de factor central unificador de su movimiento y del régimen.Discussions of democracy in contemporary Venezuela lack a settled definition of the subject, how to study it, or indeed of what counts as «democracy» in the first place.

    The president of Petroleos de Venezuela (PDV) describes the transformation of Venezuelan society and economics which has come about between 1989 and 1992 and the effect of these political changes on the oil industry in this country. While political and social unrest has been widespread before and during these changes PDV, at least, considers that a more robust economy and a better and fairer society will result than would have been possible under the oil rent system which held sway prior to 1989.

    Full Text Available Este estudo providenciou a primeira investigação sobre impacto causado pela invasão da Oreochromis niloticus sobre a população de Cichlidae nativos da bacia hidrográfica Igarapé Fortaleza, um tributário do Rio Amazonas no estado do Amapá, no Norte do Brasil. Como uma consequência de escapes e/ou liberações intencionais de O. niloticus de pisciculturas, houve a invasão e estabelecimento dessa espécie de peixe exótico no ecossistema natural, especialmente em área de refúgio, alimentação e reprodução das espécies de ciclídeos nativos.  Os fatores que contribuíram para essa invasão e estabelecimento foram aqui discutidos. A invasão de O. niloticus está causando pressão sobre as populações de ciclídeos nativos, os quais encontram-se em baixa densidade populacional, pois 72,7% da biomassa dos ciclídeos (nativos e não nativos está constituída por O. niloticus. Consequentemente, a CPUE (2,489 kg.h-1 para essa tilápia invasora é muito superior aos valores da CPUE (0,641 kg.h-1 de todas as 16 espécies de ciclídeos nativos juntos. Os resultados indicam uma necessidade de plano de manejo para controle desse peixe invasor, evitando assim a extinção de espécies de ciclídeos nativos. Além disso, serão úteis também para a tomada de decisão crítica de instituições governamentais (estadual e federal quanto à aprovação da introdução de peixes não nativos na Amazônia ou qualquer outra região do país.

    Onchocerciasis is caused by Onchocerca volvulus and transmitted by Simulium species (black flies). In the Americas, the infection has been previously described in 13 discrete regional foci distributed among six countries (Brazil, Colombia, Ecuador, Guatemala, Mexico and Venezuela) where more than 370,000 people are currently considered at risk. Since 2001, disease control in Venezuela has relied on the mass drug administration to the at-risk communities. This report provides empirical evidence of interruption of Onchocerca volvulus transmission by Simulium metallicum in 510 endemic communities from two Northern foci of Venezuela, after 10-12 years of 6-monthly Mectizan (ivermectin) treatment to all the eligible residents. In-depth entomologic and epidemiologic surveys were serially conducted from 2001-2012 in selected (sentinel and extra-sentinel) communities from the North-central (NC) and North-east (NE) onchocerciasis foci of Venezuela in order to monitor the impact of ivermectin treatment. From 2007-2009, entomological indicators in both foci confirmed that 0 out of 112,637 S. metallicum females examined by PCR contained L3 infection in insect heads. The upper bound of the 95% confidence intervals of the infective rate of the vector reached values below 1% by 2009 (NC) and 2012 (NE). Additionally, after 14 (NC) and 22 (NE) rounds of treatment, the seasonal transmission potential (±UL CIs) of S. metallicum was under the critical threshold of 20 L3 per person per season.

    Venezuela had the highest number of human malaria cases in Latin American before 1936. During 1891–1920,malaria was endemic to >600,000 km2 of this country; malaria death rates led to major population decreases during 1891–1920. No pathogen, including the influenza virus that caused the 1918 pandemic, caused more deaths than malaria during 1905–1945. Early reports of malaria eradication in Venezuela helped spark the world's interest in global eradication. We describe early approaches to malaria epidemiology in Venezuela and how this country developed an efficient control program and an approach to eradication.Arnoldo Gabaldón was a key policy maker during this development process. He directed malaria control in Venezuela from the late 1930s to the end of the 1970s and contributed to malaria program planning of the World Health Organization.We discuss how his efforts helped reduce the incidence of malaria in Venezuela and how his approach diverged from World Health Organization guidelines.

  10. [Increasing difficulties for scientific publication in Venezuela].

    Ryder, Elena

    2014-03-01

    A very important increase in the costs of the edition of scientific journals has taken place in Venezuela, due to difficulties in obtaining imported free acid paper and other materials used for handling documents. Like other journals, Investigaci6n Clinica has been considering switching completely to a digital publication format; however there are several reasons that prevent us to doing it at this time: the journal is distributed in printed form to many national institutions, which do not have immediate access to digital information. In addition, there exists a commitment of shipment of printed issues for some international indices and in exchange with other national and foreign journals, whose printed format we receive. Another important aspect is that our University maintains a weak technological platform that makes difficult the immediacy required for the interchange with authors and consulted referees of received papers; and there is a latent danger of limitations in the use of digital technologies, due to current national politic problems. Consequently, we need to continue with the printed format, but must reduce the amount of printed issues, so as not to limit the number of papers published in each edition. Nevertheless, there is an ever increasing number of contributions from foreign researches and Investigaci6n Clinica has been recently included in two new international indices, the SEIIC from Argentina and the Infobase Index from India, reasons that obligate us to maintain our levels of excellence and commitment to our authors and readers.

  11. Zulia rich coal seams to fuel Venezuela

    1983-06-16

    In March, 1982, Carbozulia awarded a contract to Fluor Corp. to provide basic engineering services, including mine planning and geology, for the two-phase project. The open pit mine and ancillary facilities, valued at more than $200 million, will provide steam and metallurgical coal for domestic use. The site, Mina Paso Diablo, is located about 60 miles northwest of Maracaibo. Upon phase one completion sometime in 1987, the mill will start production, gradually increasing to 4 million metric-tons-per-year. This will increase to 6.4 million metric tons when phase two is completed. In addition to the mine, the Venezuelan government plans to build an industrial complex along Lake Maracaibo. Corpozulia will build a steel-rolling mill and add a 350,000 metric tons-per-year coking oven, which will consume about 7% of the mine's metallurgical-coal production. Another government-owned firm, Electric Energy of Venezuela, plans to build a thermo-electric plant nearby. Two 250-megawatt units are planned initially, with potential to add another six units. At full capacity, the plant will burn more than 90% of the coal produced from the mine. Mina Paso Diablo contains one of Latin America's largest proven coal reserves - about 350 million metric tons - with guesstimates running as high as 4 billion metric tons for the Zulia coal basin. The coal is of superior quality, running about 12,000 to 13,000 Btu's per lb. with a low ash and sulphur content.

  12. Social Change and Health Policy in Venezuela

    Directory of Open Access Journals (Sweden)

    Nuramy J. Gutiérrez

    2008-07-01

    Full Text Available This work reviews social changes occurring in Venezuela during the last two decades, examining how they led to the development of a new health policy. Initially, the political context of the nineties is examined; this was a time when the neoliberal politics of the 1980’s had a demonstrable impact on the living conditions and health status of the population. By 1999 social and political events led to a new Constitution which provided the juridical and legal framework for a new health policy. The conceptualization of health and the model of health care which arose from the constitutional process are considered, as well as the reaction of the dominant economic and political sectors to the new policies imposed by constitutional mandate. The emergence of Barrio Adentro and other social missions is analyzed as an essential factor in the initiation of structural changes within the country and its health institutions. The Barrio Adentro program is described in detail, along with key steps in the development of the Venezuelan National Public Health System. Finally, the impact of these new health policies on the quality of life of the Venezuelan population is delineated.

En relación con este último aspecto, se ha venido manejando el concepto de gestión medioambiental desde diferentes perspectivas durante los últimos 50 años, por lo que en este trabajo se planteó como objetivo analizar la gestión medioambiental en Venezuela desde una perspectiva sistémica. La investigación es analítica con diseño de fuente mixta, documental y de campo; tomando como referencia datos documentales del conjunto de leyes ambientales existentes en Venezuela y datos empíricos mediante una encuesta a cinco empresas del sector petroquímico. Se evidenció que en Venezuela el Estado se apoya en una completa legislación pero no aplica instrumentos económicos que incentiven a las empresas a la protección del medioambiente, de igual modo sólo algunas organizaciones y especialmente aquellas cuyas actividades productivas pueden tener impacto ambiental significativo, como el caso de las empresas del sector petroquímico, integran el componente ecológico en sus prácticas gerenciales, presentando deficiencias en cuanto al cumplimiento de sus políticas ambientales y a la certificación de sus sistemas de gestión; por lo que aún se presenta como un reto el articular esfuerzos desde la perspectiva sistémica entre el Estado y el sector empresarial.

    To report the prevalences of hepatitis B (HBV) and hepatitis D (HDV) infections in remote and more accessible Yanomami and Piaroa Venezuelan Amazonian Amerindian populations; to estimate incidence per susceptible. Clinico-epidemiological evaluation was carried out in 9 Piaroa villages. Blood samples were tested for HBV core antibody (anti-HBc), surface antigen (HBsAg) and HDV antibody (anti-HDV). Results were analysed using logistic regression, and estimates made of HBV forces of infection (FOI). Prevalences and FOI were also estimated for 4 Yanomami villages. Mean Piaroa anti-HBc and HBsAg prevalences were 27.4% and 5.1%, respectively (up to 53% and 19% in the remote Autana region). Mean Yanomami anti-HBc and HBsAg prevalences were, respectively, 58.0% (range 43-70%) and 14.3% (31% in the village with highest HBsAg). No significant difference was found between sexes, with age and maternal HBsAg the only risk factors for HBV identified in multivariate regression of Piaroa data. Only 4 Piaroa and 2 Yanomami individuals were anti-HDV positive. Piaroa HBV prevalences were generally higher in remote villages than in less remote ones, with prevalences in Yanomami villages even higher. Anti-HBc prevalence was 47% in one Yanomami village with a history of HBV vaccination but no HBsAg cases were identified, suggestive of previously cleared or possibly transient infection or vaccine escape. Despite a past history of HDV epidemic outbreaks and HBsAg levels in some villages appearing sufficient to facilitate HDV transmission, anti-HDV prevalence was low; it remains to be established why no recent outbreaks have been reported.

    2012-08-01

    Full Text Available The focus of this article is on what role, if any, oil has on Venezuela's instability. When trying to explain why a resource-rich country experiences slow or negative growth, experts often point to the resource curse. The following pages explore the traditional theory behind the resource curse as well as alternative perspectives to this theory such as ownership structure and the correlation between oil prices and democracy. This article also explores the various forms of instability within Venezuela and their causes. Finally, the article looks at President Hugo Chavez's political and economic policies as well as the stagnation of the state oil company, Petroleos de Venezuela (PDVSA. This article dispels the myth that the resource curse is the source of destabilization in many resource dependent countries. Rather than a cause of instability, this phenomenon is a symptom of a much larger problem that is largely structural.

    Full Text Available This paper suggests a variation of the IMO index (Okun's Misery Index, adapting it to markets with these characteristics, adding the ESI level (Employment in the Informal Sector to the unemployment level. This research compares the evolution of several standard misery indexes in several zones during the last decades, with emphasis on the case of Venezuela, for which the new proposed index is also estimated. Results show improvement in the well-being of groups of countries under study, compared to the deterioration of the indicator in Venezuela. In general terms, the IMO is controlled by unemployment, except in Venezuela. However, preponderance of inflation over unemployment in this country seems to occur by the underestimate that the unemployment rate has on the Venezuelan labor market situation.

    Full Text Available Os painéis decorativos do salão nobre do Teatro Amazonas singularizam-se em relação ao restante da iconografia que decora o edifício, inaugurado em 1896. Na ocasião, as capitais do Pará e do Amazonas, enriquecidas pela economia gomífera, passaram por significativas transformações no tecido urbano e nas formas de sociabilidade, projetando-se nacional e internacionalmente. O artigo procura identificar paralelos entre as representações paisagísticas da natureza amazônica que decoram o salão nobre do edifício, a construção da cidade moderna e os usos sociais do Teatro Amazonas, símbolo do período e emblema da elite enriquecida que se afirmava no cenário regional e nacional. O Teatro Amazonas ocupou o centro da vida social da época, e em seu salão nobre ocorreram verdadeiros rituais de 'civilização' em que os convidados - brasileiros ou estrangeiros - tinham como cenário privilegiado a natureza amazônica representada nos painéis parietais decorativos.The decorative panels in the foyer of the Teatro Amazonas, inaugurated in 1896, stand out from the rest of the building's ornamental iconography. The rubber trade brought great wealth to the capitals of Pará and Amazonas and as these cities gained national and international fame, their urban fabric and forms of sociability underwent significant changes. The article looks for parallels between the landscape representations of Amazonian nature adorning the building's foyer, the construction of the modern city, and social uses of the Teatro Amazonas, symbol of the era and emblem of the newly rich elite, who were then taking their place on the regional and national stages. The Teatro Amazonas formed the center of the era's social life and its foyer played host to veritable rituals of 'civilization', in which Brazilian and foreign guests enjoyed the fine setting of Amazon's nature as represented in the decorative wall panels.

    Full Text Available INTRODUCCIÓN: Los Desórdenes por Deficiencia de Yodo son un problema serio de salud pública, con cerca de 2 mil millones de personas a riesgo de padecerlos, pudiendo causar bocio neonatal, cretinismo, retardo mental, hipotiroidismo, entre otros. Estos desórdenes son aún prevalentes, y en algunos casos los esfuerzos para su erradicación se han traducido en aumento del riesgo de exceso poblacional de yodo y autoinmunidad tiroidea. En Colombia, se desconoce el estado real de yodo en la población. OBJETIVOS: Determinar la mediana de la yoduría en población escolar, y de los hábitos del consumo de sal, función y parámetros de autoinmunidad tiroidea, y cociente intelectual. MATERIALES Y MÉTODOS: Estudio basado en la comunidad, de corte transversal. Se evaluaron las variables sociodemográficas, la frecuencia de bocio y los niveles de TSH, anti-TPO, anti-Tg, anti-TSHR, yoduria, test de factor G de Cattell, y hábitos del consumo de sal. RESULTADOS: El consumo de sal promedio persona/día fue de 18,13 g. El 37,9% presentó bocio. 36,1% tenían un valor límite en el cociente intelectual. La mediana de yoduria fue de 510,3 μg/L. El 42,75% tuvo anti-TPO positivos, y el 2,87% anti-Tg positivos. El 10% presentó niveles de TSH elevados. CONCLUSIÓN: En escolares de zona urbana, hay un exceso en la mediana de yoduria, pudiendo explicarse por el alto consumo de sal. La alta prevalencia de autoinmunidad tiroidea y bocio, junto al alto nivel de la TSH, puede ser consecuencia del exceso en la ingesta de sal y de otros factores medioambientales/ hereditarios.

    Full Text Available Nesta revisão foram investigados os principais determinantes da transição epidemiológica, nutricional e do padrão de atividade física vivenciados pelos brasileiros nas últimas três décadas. Constata-se nestas pesquisas a exclusão sistemática da região Norte-rural do novo cenário epidemiológico nacional, atualmente caracterizado pelo declínio da desnutrição infantil e elevação concomitante da obesidade, além da ausência de informações científicas a respeito das condições de saúde, nutrição e sobrevivência das populações de praticamente todos os estados da região Norte. Especificamente para o estado do Amazonas é referida a menor estatura entre as crianças brasileiras, o que evidencia exposição à carências nutricionais de longa duração. Do mesmo modo, a análise evolutiva das pesquisas regionais caracteriza a persistência de um quadro grave de insegurança alimentar. Entretanto, sabe-se que a Amazônia é detentora de uma grande diversidade em peixes e frutos, o que deveria representar uma abundante oferta e utilização de proteína de boa qualidade biológica, calorias, vitaminas, minerais, e assim, viabilizar um adequado padrão de saúde, nutrição e qualidade de vida para sua população. A realidade social e econômica, bem como o quadro de precariedade da saúde e da nutrição da Região contrastam com a sua riqueza em recursos naturais. Para o entendimento deste evidente paradoxo foram investigados os componentes do bioma amazônico quanto à: heterogeneidade, complexidade, fragilidade, interatividade e suas relações com o potencial alimentar da região, bem como seu poder de influência na determinação do binômio saúde versus nutrição para os habitantes dos seus diferentes ecossistemas.In this review were investigated the principal determinants of the epidemic transition, nutritional and of the pattern of physical activity lived on by Brazilians in the last three decades.

    This paper has been presented at DEGIT-X held in México 2005.-- Revised: 2008-08. Venezuela's growth experience over the past fifty years is characterized by a high economic growth rate from 1950 to 1970 and a low economic growth rate in the last thirty years. Although Venezuela is an oil abundant economy, this growth experience is largely accounted for by the evolution of its real non-oil GDP. We use growth accounting to quantify the extent to which the growth experience in non-oil sector...

    2014-01-01

    The structure of the gold mining industry in Venezuela has changed significantly since 1999 as a result of Government policy changes and industry response to these changes. This report documents the policy decisions that have affected the mining industry, discusses the response of the industry on a site by site basis, and suggests possible effects of these changes on the global economy. For the short term, at least, it appears that these changes have made Venezuela a more difficult place to invest for U.S. and Canadian companies, while investment by Chinese entities has been encouraged.

    The Bocono Fault Zone, the western part of the Bocono Moron-El Pilar Fault System of the southern Caribbean plate boundary, consists of aligned valleys, linear depressions, pull-apart basins and other morphological features, which extend for about 500 km in a N45[degrees]E direction, between the Tachira depression (Venezuela-Colombia border) and the Caribbean Sea. It crosses obliquely the Cordillera de Merida and cuts across the Caribbean Mountains, two different geologic provinces of Late Tertiary-Quaternary and Late Cretaceous-Early Tertiary age, respectively. Therefore, the maximum age that can be assigned to the Bocono Fault Zone is Late Tertiary (probably Pliocene). A total maximum right-lateral offset rate of 3.3 mm/a. The age of the sedimentary fill o[approximately] the La Gonzalez pull-apart basin suggests that the 7-9 km right-lateral offset necessary to produce it took place in Middle to Late Pleistocene time. The majority of seismic events are well aligned with the main fault trace; minor events are distributed in a belt several kilometers wide. Focal depth is typically 15 km and focal mechanisms indicate an average east-west compression across the zone. Return periods of 135-460 a (Richter M = 8), 45-70 a (M = 7), and 7-15 a (M = 6) have been calculated. Geodetic studies of several sites along the zone indicate compressive and right-lateral components; at Mucubaji the rate of right-lateral displacement observed is about 1 mm every 5 months (15 a of measurements).

    Full Text Available A falta de protocolos de sedação seguros para uso em papagaios na literatura demonstra a necessidade de conhecer os anestésicos que são eficazes nestes animais. Devido a pouca massa muscular desta espécie, notou-se a necessidade de estudar outra via de administração, menos invasiva e dolorosa ao animal, como a via intranasal. O objetivo deste estudo foi avaliar os efeitos sedativos e a viabilidade da administração intranasal, em comparação à via intramuscular, de 15mg/kg de Cetamina e 1mg/kg de Midazolam. Foram utilizados 14 papagaios das espécies Amazona aestiva e Amazona vinacea, de ambos os sexos, adultos, peso médio de 388,5±29,1g. Os animais foram distribuídos aleatoriamente em dois grupos: intramuscular (IM, n=7 e intranasal (IN, n=7. No grupo intramuscular, a administração dos anestésicos foi realizada nos músculos peitorais, utilizando seringas de insulina e no grupo intranasal, com auxílio de uma micropipeta. Avaliou-se o período de latência, tempo de duração, qualidade de sedação, e o tempo de recuperação total. A média para o período de latência no grupo IM foi de 6,13±2,02 minutos e no grupo IN de 4,84±2,37 minutos. Já para o tempo de duração da sedação no grupo IM a média foi de 35,81±29,56 e no grupo IN de 24,52±14,83 minutos. Ambas as vias promoveram sedação adequada, pois a média do escore da qualidade de sedação obtida pelo grupo IM foi 2±1,5 e pelo grupo IN 1,28±1,1. O tempo de recuperação total no grupo IM foi de 27,04±11,69 e no grupo IN de 17,67±11,64 minutos. Apesar do grupo IN ter apresentado os menores tempos de período de latência, duração e de recuperação total e ter obtido melhor escore na qualidade de sedação, não houve diferença estatística significativa entre os grupos.

    Safe and effective sedation protocols are important for chemical restraint of birds in clinical and diagnostic procedures, such as clinical evaluations, radiographic positioning, and blood collection. These protocols may reduce stress and ease the management of wild-caught birds, which are susceptible to injury or death when exposed to stressful situations. We compare the sedative effect of intranasal midazolam in wild-caught blue-fronted (Amazona aestiva) and orange-winged (Amazona amazonica) Amazon parrots. Ten adult parrots of each species (n = 20), of unknown sex, weighing 0.337 ± 0.04 (blue-fronted) and 0.390 ± 0.03 kg (orange-winged), kg were used. Midazolam (2 mg/kg) was administered intranasally and the total volume of the drug was divided equally between the 2 nostrils. Onset time and total sedation time were assessed. Satisfactory sedation for clinical evaluation was induced in all birds. Onset time and total sedation times were similar in both species: 5.36 ± 1.16 and 25.40 ± 5.72 minutes, respectively, for blue-fronted Amazons and 5.09 ± 0.89 and 27.10 ± 3.73 minutes, respectively, for orange-winged Amazons. A total of 15 animals showed absence of vocalization, with moderate muscle relaxation and wing movement upon handling, and 2 animals presented with lateral recumbence, with intense muscle relaxation and no wing movement, requiring no restraint. Three blue-fronted Amazons had no effective sedation. Intranasally administered midazolam at a dose of 2 mg/kg effectively promoted sedative effects with a short latency time and fast recovery in wild-caught parrots.

    Full Text Available In the State of Amazonas, Brazil, urban expansion together with precarious basic sanitation conditions and human settlement on river banks has contributed to the persistence of waterborne and intestinal parasitic diseases. Time series of the recorded cases of cholera, typhoid fever, hepatitis A and leptospirosis are described, using data from different levels of the surveillance systems. The sources for intestinal parasitosis prevalence data (non-compulsory reporting in Brazil were Medical Literature Analysis and Retrieval System Online (MEDLINE, Literatura Latino-Americana (LILACS and the annals of major scientific meetings. Relevant papers and abstracts in all languages were accessed by two independent reviewers. The references cited by each relevant paper were scrutinized to locate additional papers. Despite its initial dissemination across the entire State of Amazonas, cholera was controlled in 1998. The magnitude of typhoid fever has decreased; however, a pattern characterized by eventual outbreaks still remains. Leptospirosis is an increasing cause of concern in association with the annual floods. The overall prevalence of intestinal parasites is high regardless of the municipality and the characteristics of areas and populations. The incidence of hepatitis A has decreased over the past decade. A comparison of older and recent surveys shows that the prevalence of intestinal parasitic diseases has remained constant. The load of waterborne and intestinal parasitic diseases ranks high among the health problems present in the State of Amazonas. Interventions aiming at basic sanitation and vaccination for hepatitis A were formulated and implemented, but assessment of their effectiveness in the targeted populations is still needed.

    Full Text Available Leprosy is an ancient infectious disease caused by Mycobacterium leprae. According to comparative genomics studies, this disease originated in Eastern Africa or the Near East and spread with successive human migrations. The Europeans and North Africans introduced leprosy into West Africa and the Americas within the past 500 years. In Brazil, this disease arrived with the colonizers who disembarked at the first colonies, Rio de Janeiro, Salvador and Recife, at the end of the sixteenth century, after which it was spread to the other states. In 1854, the first leprosy cases were identified in State of Amazonas in the north of Brazil. The increasing number of leprosy cases and the need for treatment and disease control led to the creation of places to isolate patients, known as leprosaria. One of them, Colonia Antônio Aleixo was built in Amazonas in 1956 according to the most advanced recommendations for isolation at that time and was deactivated in 1979. The history of the Alfredo da Matta Center (AMC, which was the first leprosy dispensary created in 1955, parallels the history of leprosy in the state. Over the years, the AMC has become one of the best training centers for leprosy, general dermatology and sexually transmitted diseases in Brazil. In addition to being responsible for leprosy control programs in the state, the AMC has carried out training programs on leprosy diagnosis and treatment for health professionals in Manaus and other municipalities of the state, aiming to increase the coverage of leprosy control activities. This paper provides a historical overview of leprosy in State of Amazonas, which is an endemic state in Brazil.

    A 9-year-old male Yellow-headed Amazon (Amazona oratrix) with a history of anorexia and vomiting died of a liver tumor. The tumor consisted of neoplastic cells with hepatocellular and cholangiocellular differentiations and their intermingled areas. Neoplastic hepatocytes showed islands or trabecular growth with vacuolated eosinophilic cytoplasm. Cells showing biliary differentiation formed ducts or tubules lined by cytokeratin AE1/AE3-positive epithelia, accompanied by desmoplasia consisting of myofibroblasts reacting to α-smooth muscle actin and desmin. The tumor was diagnosed as a combined hepatocellular-cholangiocarcinoma, which is very rare in the avian.

    Full Text Available La lectura es un factor clave para la vida en sociedad; sin embargo, hay personas que no se han apropiado de este práctica. Este tema ha sido objeto de varias investigaciones e instancias académicas y científicas, siempre con el objetivo de lograr que la lectura sea accesible a todos. Brasil es conocido por su enorme extensión, pero carece de eficiencia en la ejecución de dichos proyectos. El Estado de Amazonas ocupa la superficie terrestre más grande del país; además, el transporte fluvial por los ríos es la única forma de acceso a las comunidades. El artículo describe un conjunto de actividades con el fin de acercar la lectura a las comunidades ribereñas, en un intento de democratizar el acceso a los libros y la lectura en ausencia de las bibliotecas públicas contribuyendo, de este modo, al proceso de inclusión informacional en la sociedad actual de la información y del conocimiento, donde la cuestión de la lectura es un desafío y, aunque sea una condición esencial, todavía existen analfabetos que necesitan ser incluidos con el fin de garantizar su participación como ciudadanos = Reading is a key factor for life in society, yet there are people who have not appropriated this habit. This theme has been the focus of various research and academic and scientific events, always with the intention of making it accessible to all.

The State of Amazonas occupies the largest land area of the country; in addition, the river transport is the only way to access to many communities. The article describes developed activities with the intention of bringing the reading to the riverside communities in an attempt to democratize access to books and reading in the absence of public libraries, contributing to the process of informational inclusion in the current society of information and knowledge where the issue of reading is

    The data of accidents caused by snakebites in Venezuela, registered at the morbidity statistics of the Direction of Epidemiology and Strategic Analysis of the Ministry of Health and Social Development were analyzed. During the years of 1996-2004, 53,792 snakebites were registered in Venezuela (5,976 cases average per year), with a higher incidence during the year 2004 (7,486 incidents). Zulia reported the highest frequency of all the states (5,975 cases); meanwhile the Midwestern region, constituted by Lara, Portuguesa, Falc6n and Yaracuy states, had a higher morbidity for snake bites. The highest incidence, distributed per states was registered in Cojedes, during the year 2001, with 228.72 cases per 100,000 inhabitants. When it was determined by regions, the highest incidence occurred during the year 2004 at los Llanos with 63.81 per 100,000 inhabitants. The median of the incidence rate for Venezuela during the period was of 21.46 accidents per 100,000 inhabitants. The classification of the endemic areas for ophidism, according to the percentiles 23, 50, 75 and 90, organized the country in: (a) states and regions of very high endemicity, (b) high endemicity, (c) middle, (d) low and (e) very low endemicity. These epidemiological data indicated that the accidents caused by snakes constitute a collective health problem in Venezuela.

  10. CYP2D6 variability in populations from Venezuela.

    2016-12-01

    CYP2D6 is an important cytochrome P450 enzyme that plays an important role in the metabolism of about 25% of currently prescribed drugs. The presence of polymorphisms in the CYP2D6 gene may modulate enzyme level and activity, thereby affecting individual responses to pharmacological treatments. The most prevalent diseases in the admixed population from Venezuela are cardiovascular and cancer, whereas viral, bacterial and parasitic diseases, particularly malaria, are prevalent in Amerindian populations; in the treatment of these diseases, several drugs that are metabolized by CYP2D6 are used. In this work, we reviewed the data on CYP2D6 variability and predicted metabolizer phenotypes, in healthy volunteers of two admixed and five Amerindian populations from Venezuela. The Venezuelan population is very heterogeneous as a result of the genetic admixture of three major ethnical components: Europeans, Africans and Amerindians. There are noticeable inter-regional and inter-population differences in the process of mixing of this population. Hitherto, there are few published studies in Venezuela on CYP2D6; therefore, it is necessary to increase research in this regard, in particular to develop studies with a larger sample size. There is a considerable amount of work remaining before CYP2D6 is integrated into clinical practice in Venezuela.

    Arid zones of northern Venezuela are represented by isolated areas, important from an ornithological and ecological perspective due to the occurrence of restricted-range species of birds. We analysed the prevalence and molecular diversity of haemosporidian parasites of wild birds in this region by screening 527 individuals (11 families and 20 species) for parasite mitochondrial DNA. The overall prevalence of parasites was 41%, representing 17 mitochondrial lineages: 7 of Plasmodium and 10 of Haemoproteus. Two parasite lineages occurred in both the eastern and western regions infecting a single host species, Mimus gilvus. These lineages are also present throughout northern and central Venezuela in a variety of arid and mesic habitats. Some lineages found in this study in northern Venezuela have also been observed in different localities in the Americas, including the West Indies. In spite of the widespread distributions of some of the parasite lineages found in northern Venezuela, several, including some that are relatively common (e.g. Ven05 and Ven06), have not been reported from elsewhere. Additional studies are needed to characterize the host and geographical distribution of avian malaria parasite lineages, which will provide a better understanding of the influence of landscape, vector abundance and diversity, and host identity on haemosporidian parasite diversity and prevalence.

    Weisbrot, Mark; Sandoval, Luis; Rosnick, David

    2006-01-01

    This article looks at household and individual poverty rates in Venezuela over the past seven years. For more than a year, the statement that poverty in Venezuela has increased under the government of President Hugo Chávez has appeared in scores of major newspapers, on major television and radio programs, and even in publications devoted to foreign policy. There are no data to support such statements, and in fact the available data show a decline in poverty for both individuals and households over the seven-year period: the percentage of people in poverty declined from 50 percent in the first quarter of 1999 to 43.7 percent in 2005. Further, there is no evidence to suggest any change in the methodology for measuring poverty during this period, as has been alleged in a number of reports. The article also examines briefly the impact of significant changes in non-cash benefits such as free health care, which are not taken into account in the measured poverty rate, on poor people in Venezuela. Finally, the authors look at how the mistakes in reporting on Venezuela's poverty rate were made; an appendix gives examples of mistakes in major media and foreign policy publications.

    Energy Technology Data Exchange (ETDEWEB)

    1977-07-01

    Venezuela has pioneered the production of heavy oil, according to Dr. A. Guzman-Reyes, director general of hydrocarbons for the Venezuelan government. The first heavy oil production began in Venezuela 60 yr ago and the oil industry has steadily improved methods of producing and handling heavy oil. The country's producing fields are capable of yielding almost one million barrels of heavy oil daily, although actual production, largely because of market limitations, is about 650,000 bpd. Canada's daily heavy oil production, including the 60,000 bbl of synthetic crude produced daily by the Great Canadian Oil Sands plant, is about 200,000 bbl. Dr. Guzman-Reyes stated that Venezuela intends to rapidly develop heavy oil production and upgrade facilities to maintain its export markets. The national oil company, Petroleos de Venezuela, plans to invest 4 times the amount spent on oil development over the last 60 yr during the next 10 yr, a total of $3 billion by 1980.

    Full Text Available Resumen Venezuela transita desde 1999 por un proceso propio de transformación impulsado por el Estado. La aprobación de políticas alternativas plasmadas en una nueva constitución, en las leyes aprobadas en el marco de ésta y en otros documentos, dan cuenta de una nueva orientación dirigida a romper con las tendencias neoliberales de los 90 del pasado siglo. Desafortunadamente, en cuanto a los procesos de gestión, es evidente la presencia de viejas prácticas que obstaculizan los avances, aunque se maneja la hipótesis de que en este contexto existen algunos procesos innovadores vinculados a las políticas alternativas. El propósito de este trabajo es explorar la presencia de estos procesos en la gestión pública venezolana, vinculados a la nueva política. La metodología consistió en el análisis de documentos oficiales y fuentes secundarias, así como entrevistas abiertas a actores que han estado cerca de algunos de los procesos innovadores. Los resultados dan cuenta de: 1 Procesos de desconcentración flexibles que acerca el Estado al ciudadano; 2 Comunicación argumentativa a los ciudadanos, sobre las nuevas políticas; 3 Un sistema de participación que potencia la incorporación de los ciudadanos en la defensa de los intereses colectivos; 4 Estrategias de articulación sectorial e institucional; 5 Procesos de incorporación del sector privado a las políticas de inclusión social; 6 Sistemas de compras y financiamiento como promotores de la economía social. Se concluye que en el marco de un aparato público que se niega al cambio se han introducido formalmente algunos procesos innovadores, cuya práctica aún está pendiente por comprender.AbstractSince 1999, Venezuela is going through a transformation process launched by the State.

    The Puerto Rican parrot ( Amazona vittata ) has become an iconic and high-profile conservation species. The cornerstone of the recovery plan for this critically endangered species is an active captive breeding program, management of the wild population, and a long-term reintroduction program. In 2002, 40 adult Puerto Rican parrots that had not produced viable offspring were selected for reproductive assessment at 2 aviary populations in Puerto Rico (Iguaca and Río Abajo), which are the only sources of parrots for release. The goal was to enhance reproductive potential and produce productive pairings in an attempt to augment the population growth and provide ample individuals for reintroduction. Seven Hispanolian Amazon parrots ( Amazona ventralis ) that were used as surrogate parents for the Puerto Rican parrots were also included in the study. This assessment included physical examination, endoscopic evaluation, hematologic and plasma biochemical profiles, viral screening, and hormonal assays. Results of general physical examination and hematologic and plasma biochemical testing revealed overall good health and condition of this subset of the population of Puerto Rican parrots; no major infectious diseases were found. Endoscopic examination also revealed overall good health and condition, especially of females. The apparent low fertility of male birds warrants further investigation. The findings helped to define causes of reproductive failure in the selected pairs and individual birds. New pairings resulting from the assessment helped to augment reproduction of this critically endangered species.

    2018-03-01

    The Brazilian Paleozoic ichthyofauna from the Parnaíba and Amazonas basins regard a sparsely known diversity, including chondrichthyans and acanthodians, besides some osteichthyan remains. This work proposes a revision of the fossil material from these two sedimentary basins and synthesizes the morphological aspect of such material trying to understand the influences of those fossils to the paleontology of the region, comparing the Brazilian fossils with other gondwanan faunas. The Brazilian Paleozoic fish fauna shows great resemblance to those of Bolivia, especially during the Devonian. Many of the Acanthodian spines from the Manacapuru Formation (Amazonas Basin), and the Pimenteira Formation (Parnaíba Basin), are comparable to the taxa found in Bolivia. The lack of more Placoderm remains in the Brazilian outcrops is similar to the low diversity of this group in Bolivia, when compared to other South American and Euramerican localities. The most diverse Brazilian ichthyofauna is encountered in the Permian Pedra de Fogo Formation where numerous chondrichthyans and 'paleopterygians' remains are found, together with dipnoans and actinistians. Despite the apparent lack of more representative Paleozoic ichthyofaunas in Brazil, the available material that ranges from Lower Devonian to early Permian from Brazil bears important taxa that could address valuable taxonomic and biogeographic informations.

La oposición, encabezada por Henrique Capriles, se niega a reconocer el triunfo en las urnas del candidato socialista Nicolás Maduro. Capriles ha llamado a sus seguidores, de forma solapada, a no reconocer la victoria de Maduro, y ha estimulado actos de violencia en todo el país. Algunos centros médicos donde trabajan colaboradores cubanos no han escapado de esa violencia. Nuestros colaboradores, sin embargo, han seguido cumpliendo con su deber, por la razón que los llevó a la tierra de Bolívar: “atender a cada ciudadano venezolano que requiera de sus servicios, independientemente de la filiación política, clase social, u otras consideraciones,” como dijo al periódico Granma el viceministro cubano de Salud, Dr. Roberto González Martín. Pero nuestros hermanos cubanos no han estado solos. Se ha desarrollado un movimiento voluntario, espontáneo de protección entre los venezolanos, como muestra del cariño y respeto que se han ganado los profesionales cubanos entre los pobladores de los barrios populares. Se sabe, los venezolanos saben, que la presencia de los médicos, enfermeras y técnicos cubanos se debe únicamente  a dos nobles objetivos, el de brindar atención médica a todo el que lo necesite y el contribuir a la formación de médicos venezolanos, que ya en cifra de cerca de 15 mil se han graduado con la ayuda de los profesionales cubanos.

How did the antagonisms between the opponent group and the Governmental one reflect the contradictions between National-States and neoliberal globalization? These questions will be answered in this study.   Keywords: Coup d’April, neoliberal globalization, National-State, classes struggle

    2008-12-01

    Full Text Available El presente articulo pretende examinar la evolución del debate constitucional sobre las relaciones Estado–Iglesia en nuestro pais, el actual diseno de estas relaciones a partir de lo dispuesto por el texto constitucional vigente y el Acuerdo suscrito con la Iglesia Catolica en julio de 1980, asi como los alcances de un proyecto de ley que pretende regular la libertad e igualdad religiosas. Asumiendo tal perspectiva recordaremos algunos antecedentes constitucionales que nos muestran por donde se ha encaminado el debate; y examinaremos los principios que orientan la relacion Iglesia-Estado, desde un enfoque de derechos fundamentales y en el marco de la indispensable afirmacion de un Estado Constitucional de Derecho. Ello es particularmente relevante en un pais como el nuestro en donde determinadas concepciones religiosas pretenden establecerse como unico parametro para la adopcion de aquellas politicas publicas respecto a las cuales la Iglesia tiene una posicion definida.

    Faced with the need to import increasing volumes of crude oil and the desire to avoid over-dependence on the Middle East, the United States is looking to its own hemisphere for more oil. Unfortunately for Washington, the continent's largest oil exporter does not appear to want to co-operate. Venezuela's President, Hugo Chavez, wants to reduce his country's political and economic ties with the US and is seeking other markets for its oil. He has also picked a fight with US oil companies operating in Venezuela, disputing their taxes and refusing to approve their upstream investment programmes, giving rise to fears that oil and gas production will not grow as planned, thereby reducing future export levels.

    Full Text Available Paxillus is a neotropical genus belonging to the subfamily Passalinae widespread from Mexico to Argentina. Brazil is known to harbor five species belonging to this genus with most of them presenting at head a flattened central tubercle lacking a free apex. However, one of these species, Paxillus macrocerus Reyes-Castillo & Fonseca, differs from that pattern by having a long central tubercle with a completely free apex. The present study describes and illustrates another new species, which has been found in the Brazilian Amazon, showing this same characteristic.Paxillus é um gênero neotropical pertencente à subfamília Passalinae, distribuído do México até a Argentina.

    Full Text Available Despite the importance of citriculture in Brazil, very little is known about mite populations in citrus crops in the Northern Region. In the municipality of Manaus, 12 sprayed sweet orange orchards were surveyed every two weeks during seven months to record mite species amount, and to describe the abundance and distribution of the most important species. The size and age of the orchards varied from 3,360 to 88,080 m² and seven to 25 years, respectively. In the fourteen sampling period, leaves, twigs and fruits were collected from 12 trees, one per orchard. In total, 3,360 leaves, 672 twigs and 1,344 fruits were sampled from 168 trees. Mites were manually extracted from the fruits, and by the washing method on leaves and twigs. We identified pests with the potential to cause economic loss. Fourteen species of phytophagous and mycophagous mites from Eriophyidae, Tarsonemidae, Tenuipalpidae, and Tetranychidae were recorded. Brevipalpus phoenicis (Geijskes 1939 and Phyllocoptruta oleivora (Ashm., 1879, the two commonest phytophagous mites in other Brazilian regions were dominant, showing that local orchards are susceptible to their infestation. Eleven predatory mites were recorded, comprising 10% of the mite population, belonging to Phytoseiidae and Ascidae. Phytoseiidae was the richest family, with ten species. The results are discussed in relation to the temporal variation aspects and habitat use of the most important species. Long-term research encompassing chemical applications followed by evaluations of the mite community are necessary for a better management of the orchards, taking into consideration the seasonal phenology of key pests.Apesar da importância da citricultura no Brasil, pouco se conhece sobre as populações de ácaros em plantações de citros no norte do país. No município de Manaus, 12 pomares de laranja doce pulverizados foram avaliados a cada duas semanas, durante sete meses, para o registro de ácaros plantícolas e para descrever a abundância e a distribuição das espécies mais importantes. O tamanho e a idade dos pomares variaram de 3.360 a 88.0080 m² e de sete a 25 anos, respectivamente. Nos 14 períodos de coleta, folhas, galhos e frutos foram coletados de uma árvore em cada pomar. No total, 3.360 folhas, 672 galhos e 1.344 frutos foram coletados de 168 árvores. Os ácaros foram extraídos dos frutos manualmente e pelo método de lavagem nas folhas e galhos. Identificamos espécies pragas com potencial de causar danos econômicos. Registramos 14 espécies de fitófagos em quatro famílias (Eriophyidae, Tarsonemidae, Tenuipalpidae, and Tetranychidae. Brevipalpus phoenicis (Geijskes 1939 (Tenuipalpidae e Phyllocoptruta oleivora (Ashm., 1879 (Eriophyidae, as duas espécies fitófagas mais abundantes em outras regiões, foram dominantes, mostrando que a cultura de citros local é suscetível à infestação. Registramos 11 espécies de predadores das famílias Phytoseiidae e Ascidae, compreendendo 10% da população total. Phytoseiidae foi a família mais diversa, com 10 espécies. Foram discutidos aspectos da variação temporal e utilização de hábitat das espécies mais abundantes. Estudos de longo prazo, envolvendo a aplicação de acaricidas e avaliações da comunidade de ácaros, são necessários para um melhor manejo dos pomares, levando-se em consideração a fenologia das pragas-chave.

    Eid, Mahmoud; Nahon-Serfaty, Isaac

    2015-01-01

    The prevalence of breast cancer in Venezuela is particularly alarming, which is attributed to healthcare inequalities, low health literacy, and lagging compliance with prevention methods (i.e., screening and mammography). While the right to health is acknowledged by the Venezuelan constitution, activism beyond governmental confines is required to increase women's breast cancer awareness and decrease mortality rates. Through the development of social support and strategic communicative methods enacted by healthcare providers, it may be possible to empower women with the tools necessary for breast cancer prevention. This paper discusses issues surrounding women's breast cancer, such as awareness of the disease and its risks, self-advocacy, and the roles of activists, healthcare providers, and society. Specifically, it describes a four-year action-oriented research project developed in Venezuela, which was a collaborative work among researchers, practitioners, NGOs, patients, journalists, and policymakers. The outcomes include higher levels of awareness and interest among community members and organizations to learn and seek more information about women's breast cancer, better understandings of the communicated messages, more media coverage and medical consultations, increasing positive patient treatments, expansion of networking of NGOs, as well as a widely supported declaration for a national response against breast cancer in Venezuela.

    In 1999, newly-elected Venezuelan President Hugo Chávez initiated a far-reaching social movement as part of a political project known as the Bolivarian Revolution. Inspired by the democratic ideologies of Simón Bolívar, this movement was committed to reducing intractable inequalities that defined Venezuela's Fourth Republic (1958-1998). Given the ambitious scope of these reforms, Venezuela serves as an instructive example to understand the political context of social inequalities and population health. In this article, we provide a brief overview of the impact of egalitarian policies in Venezuela, stressing: (a) the socialist reforms and social class changes initiated by the Bolivarian Movement; (b) the impact of these reforms and changes on poverty and social determinants of health; (c) the sustainability of economic growth to continue pro-poor policies; and (d) the implications of egalitarian policies for other Latin American countries. The significance and implications of Chávez's achievements are now further underscored given his recent passing, leading one to ask whether political support for Bolivarianism will continue without its revolutionary leader.

  11. Violence in Venezuela: oil rent and political crisis

    2006-06-01

    Full Text Available This article analyzes the changes in violence in Venezuela during the last forty years. It links the ups and downs of the oil revenues and the political crisis of the country to the changes in the homicide rates, which increased from 7 per 100 thousand inhabitants in 1970 to 12 in 1990, 19 in 1998 and 50 in 2003. The article characterizes Venezuela as a rentist society and shows its trajectory from rural violence to the beginning of urban violence, the guerilla movements of the 60s, the delinquent violence related to the abundance of oil revenues and the violence during the popular revolt and the sackings of 1989 in Caracas. After this, we analyze the coups d'état of 1992 and the influence the political violence exerted upon criminal violence. We describe the political and party changes in the country, their influence upon the stabilization of homicide rates since the mid-90s and their remarkable increase during the H. Chávez government. The article finishes with an analysis of the current situation, the official prohibition to publish statistics on homicides and with some thoughts about the perspective of greater violence in Venezuela.

    The scope of this paper was to analyze the perception of community-based organizations and their contributions to the history of tackling Aids in Amazonas State. It involved qualitative research with the use of oral and documental sources. Data were collected between June and September 2013 by means of semi-structured interviews with the leaders of eight organizations that work or worked with more vulnerable communities. Based on Discourse Analysis the conclusion drawn is that that the organizations perceive two distinct phases since the decentralization of funds from the Sexually-Transmitted Diseases Aids and Viral Hepatitis Department to the local leaders. The first phase was marked by the strengthening of organizations, collective empowerment and active political participation. The current phase has seen the distancing between organizations, a loss of political momentum and weakening of common response and organization.

Data were collected through interviews and observations concerning to the knowledge and everyday practices of the use of medicinal animals. About 60 animal species are known with medicinal purposes. The knowledge is well distributed between sexes (men and women and localities (urban and rural. The use of medicinal animals is embedded in etiological concepts and involves a complex cosmological vision of the cure process. The rural exodus and the facilitated access to the western medicine may be promoting the loss of the traditional knowledge, which can be mitigated through the valorization and transmission of this knowledge to the future generations.

    Carlos Mario Jaramillo

    Full Text Available Hepatitis B Virus (HBV infection is a worldwide public health problem. In the 1980's a highly effective and safe vaccine against HBV was developed, although breakthrough infection still occasionally occurs because of the emergence of escape mutants. The aim of this study was to identify HBV genotypes and escape mutants in children and their mothers in Amerindian communities of the Amazonas State, Southern Colombia.Blood specimens collected from children and mothers belonging to 37 Amerindian communities in Amazonas state, were screened for HBsAg and anti-HBc using ELISA. The partial region containing the S ORF was amplified by nested PCR, and amplicons were sequenced. The phylogenetic analysis was performed using the MEGA 5.05 software.Forty-six children (46/1275, 3.6% and one hundred and seventy-seven mothers (177/572, 30.9% were tested positive for the anti-HBc serological marker. Among them, 190 samples were tested for viral genome detection; 8.3% (2/31 serum samples obtained from children and 3.1% (5/159 from mothers were positive for the ORF S PCR. The predominant HBV genotype in the study population was F, subgenotype F1b; in addition, subgenotype F1a and genotype A were also characterized. Two HBV escape mutants were identified, G145R, reported worldwide, and W156*; this stop codon was identified in a child with occult HBV infection. Other mutations were found, L109R and G130E, located in critical positions of the HBsAg sequence.This study aimed to characterize the HBV genotype F, subgenotypes F1b and F1a, and genotype A in Amerindian communities and for the first time escape mutants in Colombia. Further investigations are necessary to elucidate the frequency and the epidemiological impact of the escape mutants in the country.

    Full Text Available This study evaluated the occurrence of American tegumentary leishmaniasis (ATL in the State of Amazonas, Brazil, in the last 30 years with emphasis on the last 10 years (2001 to 2010. The disease was predominantly observed in males (76.2%, in the 21- to 30-year-old age group (26.6% and in extractive workers (43.7%; 3.3% of the cases were the mucosal form. The endemic channel shows the disease seasonality, with a predominance of cases at the beginning and end of each year. The number of cases by municipality in the period of 2001-2010 shows the maintenance of the endemic in the localities where the highest numbers of cases have always been registered, namely, Manaus, Rio Preto da Eva, Itacoatiara and Presidente Figueiredo. The comparison of data from 2001 to 2005 and from 2006 to 2010 showed the emergence of this disease in municipalities that had been previously unaffected. In the last years, there has been a significant increase in the activities of control, diagnosis and treatment of leishmaniasis in the State of Amazonas. In conclusion, the historical series of ATL analyzed in this study suggests that the transmission foci remain and are even expanding, though without continuous transmission in the intra- or peridomicile settings. Moreover, the disease will persist in the Amazon while the factors associated with infection acquisition relative to forest exploitation continue to have economic appeal. There is a real expectation of wide variations in disease incidence that can be influenced by climate and economic aspects.

In the state of Amazonas, Brazil during the 2011 outbreak of dengue all the four Dengue virus (DENV serotypes circulating simultaneously were observed. The aim of the study was to describe the clinical epidemiology of dengue in Manaus, the capital city of the state of the Amazonas, where all the four DENV serotypes were co-circulating simultaneously.Patients with acute febrile illness during the 2011 outbreak of dengue, enrolled at the Fundação de Medicina Tropical Dr. Heitor Viera Dourado (FMT-HVD, a referral centre for tropical and infectious diseases in Manaus, were invited to participate in a clinical and virological descriptive study. Sera from 677 patients were analyzed by RT-nested-PCRs for flaviviruses (DENV 1-4, Saint Louis encephalitis virus-SLEV, Bussuquara virus-BSQV and Ilheus virus-ILHV, alphavirus (Mayaro virus-MAYV and orthobunyavirus (Oropouche virus-OROV.Only dengue viruses were detected in 260 patients (38.4%. Thirteen patients were co-infected with more than one DENV serotype and six (46.1% of them had a more severe clinical presentation of the disease. Nucleotide sequencing showed that DENV-1 belonged to genotype V, DENV-2 to the Asian/American genotype, DENV-3 to genotype III and DENV-4 to genotype II.Co-infection with more than one DENV serotype was observed. This finding should be warning signs to health authorities in situations of the large dispersal of serotypes that are occurring in the world.

    Science.gov (United States)

    2013-01-01

    Background Onchocerciasis is caused by Onchocerca volvulus and transmitted by Simulium species (black flies). In the Americas, the infection has been previously described in 13 discrete regional foci distributed among six countries (Brazil, Colombia, Ecuador, Guatemala, Mexico and Venezuela) where more than 370,000 people are currently considered at risk. Since 2001, disease control in Venezuela has relied on the mass drug administration to the at-risk communities. This report provides empirical evidence of interruption of Onchocerca volvulus transmission by Simulium metallicum in 510 endemic communities from two Northern foci of Venezuela, after 10–12 years of 6-monthly Mectizan® (ivermectin) treatment to all the eligible residents. Methods In-depth entomologic and epidemiologic surveys were serially conducted from 2001–2012 in selected (sentinel and extra-sentinel) communities from the North-central (NC) and North-east (NE) onchocerciasis foci of Venezuela in order to monitor the impact of ivermectin treatment. Results From 2007–2009, entomological indicators in both foci confirmed that 0 out of 112,637 S. metallicum females examined by PCR contained L3 infection in insect heads. The upper bound of the 95% confidence intervals of the infective rate of the vector reached values below 1% by 2009 (NC) and 2012 (NE). Additionally, after 14 (NC) and 22 (NE) rounds of treatment, the seasonal transmission potential (±UL CIs) of S. metallicum was under the critical threshold of 20 L3 per person per season. Serological analysis in school children < 15 years-old demonstrated that 0 out of 6,590 individuals were harboring antibodies to Ov-16. Finally, epidemiological surveys made during 2010 (NC) and 2012 (NE) showed no evidence of microfilariae in the skin and eyes of the population. Conclusions These results meet the WHO criteria for absence of parasite transmission and disease morbidity in these endemic areas which represent 91% of the population previously at

    Full Text Available La formulación de políticas públicas subnacionales (Estados y Municipios de apoyo a la economía social se inició en Venezuela con los procesos de descentralización y reestructuración neoliberal de la economía en los noventa. El propósito de este trabajo es explorar en varias gobernaciones las características de estas estrategias gubernamentales y las posibilidades que tienen las gobernaciones de insertarse en un proyecto alternativo de fomento a la economía social prevista en la nueva constitución. Todo esto plantea, para el proceso conocido como Revolución Bolivariana, un escenario de fuertes tensiones intergubernamentales y riesgos políticos para un proyecto transformador que toma expresión en: a diferencias conceptuales y referenciales del sector de la economía social hacia las microempresas en contraposición con las cooperativas, b obstáculos para lograr cooperación en las relaciones intergubernamentales necesarias para la puesta en práctica de la política, producto de condicionamientos de los modelos administrativos de las gobernaciones venezolanas, c duplicidad de funciones entre agencias nacionales y subnacionales de las políticas en el marco de serias restricciones fiscales y regulaciones constitucionales. Se concluye que las políticas subnacionales de fomento a la economía social se caracterizaron en la década de los noventa y siguen caracterizándose, por dar respuestas a los requerimientos de una economía de mercado con poco sentido social, lo que representa una importante contradicción para un proyecto alternativo de desarrollo que incluye estos ámbitos gubernamentales como espacios de actuación de los poderes públicos para el fortalecimiento de la democracia.

    Full Text Available INTRODUCCIÓN: el infarto agudo del miocardio constituyó más del 12 % de los fallecimientos por cardiopatía isquémica en Venezuela en 2006, sin evidenciarse disminución en la mortalidad a pesar del mejoramiento tecnológico de los servicios de urgencias. OBJETIVO: caracterizar su comportamiento en los centros de diagnóstico integrales del Estado de Vargas, en el período comprendido de junio de 2006 a junio de 2009. MÉTODOS: se realizó un estudio descriptivo, retrospectivo para caracterizar el comportamiento del infarto agudo del miocardio en los servicios de urgencia y emergencia de los centros de diagnóstico integrales utilizando las estadísticas de la Misión Barrio Adentro. RESULTADOS: fueron atendidos 186 pacientes por infarto agudo del miocardio, predominaron los ingresos en la terapia intensiva (2,4 % sobre los servicios de hospitalización. Los fallecidos por esta causa fueron 35 personas, 17,1 % del total de fallecidos. Fueron trombolizados el 39,2 %, con el mayor número alcanzado en el 2008 con 51,2 %. La letalidad por infarto agudo del miocardio osciló entre tasas de 17,3 y 20 por cada 100 pacientes vistos. La tasa de mortalidad bruta fue de 9,58 x 100 000 habitantes. CONCLUSIONES: el número de casos atendidos por infarto tuvo un comportamiento ascendente de manera estable, representaron el 0,7 % del total de ingresos en estos centros, con predominio de los ingresos en la terapia intensiva sobre los servicios de hospitalización. Se le aplicó el tratamiento trombolítico con estreptoquinasa recombinante a un por ciento importante de enfermos. En los servicios de hospitalización fue superior la letalidad por esta causa. No disminuyó el riesgo de morir para los pacientes con esta enfermedad y la mortalidad general en el período estudiado fue de 35 pacientes para una tasa de 9,58 × 100 000 habitantes.INTRODUCTION: the acute myocardial infarction was over the 12 % of deceased from ischemic heart disease in Venezuela in

    Full Text Available La Psicología Social Comunitaria cuenta con un sostenido desarrollo  teórico y metodológico que representa un gran potencial de aplicabilidad en la solución de diversos problemas sociales y en el desarrollo de las comunidades.  Por su parte, el contexto venezolano actual, donde casi todas las políticas públicas implican un alto nivel de protagonismo de la organización y la participación comunitaria, es sumamente propicio para que las ciencias sociales en general y, la Psicología Social Comunitaria en particular, integren sus aportes. En función de estos planteamientos, en el presente trabajo presentamos una experiencia realizada en el marco de la Gran Misión Vivienda Venezuela, política pública impulsada por el estado venezolano que asume una perspectiva comunitaria y participativa. La experiencia en cuestión se desarrolló entre diciembre del 2013 y diciembre del 2014 y estuvo adscripta al Gobierno del Distrito Capital, en Caracas, Venezuela. Tuvo como eje central el desarrollo e implementación de un Enfoque Comunitario Integral destinado a servir de orientación al trabajo que realizaron los equipos con las poblaciones ubicadas en los nuevos urbanismos construidos por el estado. El diseño e implementación del Enfoque, integró buena parte de las propuestas teórico -  conceptuales de la Psicología Comunitaria.   Palabras clave: vivienda, comunidad, organización, participación, políticas públicas.

    Being a form of cheap energy, abundant and accessible, the vegetable coal is quite often used generally in the urban and rural areas in the Amazonas state, domestic and commercial use as well. Several families live of the production activity and commercialization of vegetable coal inside the State of Amazonas. However, actions of government organs of the environment area turn more and more difficult the exercise of those activities, creating a situation of clandestine production and in some cases making unfeasible the only form of subsistence of several families. Besides the legal aspect there exist the low technological level, being the production of vegetable coal done in ovens of the type 'hot tail', which cause problems for the users health. The mentioned subjects are discussed in that work based on the study accomplished at three places producing the vegetable coal in the the State of Amazonas hinter side, in the proximities of Manaus. Through the information obtained in the communities a proposal is presented for the small scale production of vegetable coal in a economical, social and environmentally self sustainable way.

    Full Text Available The larva, pupa, male and female of Simulium tergospinosum n. sp. are described and illustrated. The adults of this new species share many characters with species in the subgenus Psaroniocompsa, where it is placed. The larva of this species bears dorsal and lateral triangular tubercles on the abdomen and multiply branched scale-like setae on the body, suggesting that it belongs to the S. siolii species group. S. tergospinosum n.sp. was collected along the Juma River, Apuí county, in the southern part of the State of Amazonas, Brazil. The Juma, a black-water river, is a tributary of the Aripuanã River in the Madeira River hydrographic basin, on the southern part of Amazonas. Females were collected biting humans along the water courses during the sampling period (in the dry season.

    Full Text Available The main objective of the present text is to analyze environmental governance in the Sustainable Development Reserve Igapó-Açu, located in the municipalities of Manicoré, Borba and Beruri, state of Amazonas, Brazil. The study area was chosen because the RDS is the only Amazonas state protected area crossed by a federal interstate highway. This highway provides a specific territorial arrangement of governance elements in the studied area. Different methodological tools were used in this research, such as close-ended questionnaires and open-ended interviews. Data were systematized using Excel software and they were graphically represented in the form of organizational charts drawn with Websphere Analysis Software. Results indicate that environmental governance of the RDS Igapó-Açu involves multiple factors, while the central node of the local political articulation is held by a Management Council that is in charge of materializing the governability of the RDSt, as well as its ramifications.

    Full Text Available We investigated the use of Bacillus thuringiensis isolated in the state of Amazonas, in Brazil, for the biological control of the dengue vector Aedes aegypti. From 25 soil samples collected in nine municipalities, 484 bacterial colonies were obtained, 57 (11.78% of which were identified as B. thuringiensis. Six isolates, IBt-03, IBt-06, IBt-07, IBt-28, IBt-30, and BtAM-27 showed insecticidal activity, and only BtAM-27 presents the five genes investigated cry4Aa, cry4Ba, cry10Aa, cry11Aa, and cry11Ba. The IBt-07 and IBt- 28, with lower LC50 values, showed equal toxicity compared to the standards. The isolates of B. thuringiensis from Amazonas constitute potential new means of biological control for A. aegypti, because of their larvicidal activity and the possibility that they may also contain new combinations of toxins.

    Full Text Available Envenoming snakebites are thought to be a particularly important threat to public health worldwide, especially in rural areas of tropical and subtropical countries. The true magnitude of the public health threat posed by snakebites is unknown, making it difficult for public health officials to optimize prevention and treatment. The objective of this work was to conduct a systematic review of the literature to gather data on snakebite epidemiology in the Amazon region and describe a case series of snakebites from epidemiological surveillance in the State of Amazonas (1974-2012. Only 11 articles regarding snakebites were found. In the State of Amazonas, information regarding incidents involving snakes is scarce. Historical trends show an increasing number of cases after the second half of the 1980s. Snakebites predominated among adults (20-39 years old; 38%, in the male gender (78.9% and in those living in rural areas (85.6%. The predominant snake envenomation type was bothropic. The incidence reported by the epidemiological surveillance in the State of Amazonas, reaching up to 200 cases/100,000 inhabitants in some areas, is among the highest annual snakebite incidence rates of any region in the world. The majority of the cases were reported in the rainy season with a case-fatality rate of 0.6%. Snakebite envenomation is a great disease burden in the State of Amazonas, representing a challenge for future investigations, including approaches to estimating incidence under-notification and case-fatality rates as well as the factors related to severity and disabilities.

    Full Text Available El propósito de este artículo consiste en plantear algunos problemas que bloquean el camino hacia el desarrollo político y constituyen tarea urgente para el gobierno. Asimismo se trata de hacer un aporte abordando áreas estratégicas importantes en las estructuras del poder como es el caso de las políticas públicas, tal vez la más reciente e innovadora corriente de análisis presente en la Ciencia Política, incluyendo la política social como una de las exigencias de los ciudadanos frente al Estado y la democracia. Bajo este punto de vista las políticas públicas son consideradas una estrategia básica para legitimar el rendimiento del gobierno. Por último se abordan ciertos resultados de la mala política y sus efectos sobre la democracia pues, así lo entendemos, en Venezuela las tareas del gobierno en materia de políticas públicas han estado marcadas por una visión formalmente bien intencionada, pero que operativamente ha sido bloqueada por factores perturbadores como por ejemplo: la inconsistencia en la toma de decisiones, el centralismo, la corta visión para acercarse a los parámetros de una gerencia pública moderna, la excesiva politización de los trámites administrativos para emprender acciones concretas y la relación asimétrica entre el tamaño del Estado y la calidad del Estado, todo lo cual impide la realización correcta de los procedimientos para profundizar en la tarea obtener logros efectivos y eficientes en materia de política social y el avance hacia la modernización del sector público. .

    This paper reports on Venezuela which continues efforts to position itself in world markets to capitalize on fallout from the Persian Gulf war. The central government and state oil company Petroleos de Venezuela SA have accelerated already ambitious plans to expand activities in upstream and downstream oil and gas sectors. Pvdsa has sharply increased its 1991-96 investment program from the level planned at the end of last year. The goal is to put Venezuela on a par with major Persian Gulf oil exporters in terms of productive capacity. Linchpin of those efforts could well be further steps toward privatization of Venezuela's oil sector. For the first time since nationalization in 1976, private foreign and domestic companies are being permitted to participate in Venezuelan exploration and development. In addition, the government is trimming the onerous tax burden the oil sector has carried in Venezuela, as well as its heavy subsidy of domestic petroleum products

Este estudio se desarrolló en la Unidad de Investigación de Análisis de Políticas Públicas y Desarrollo Socio-educativo de la Universidad de Carabobo. Tomando como referencias teóricas a E. Morin y J. Habermas, se desarrollan tres categorías presentes en la realidad de Venezuela: el Socialismo del Siglo XXI, el Estado Docente y la Autonomía Universitaria. El tratamiento metodológico parte del planteamiento de la premisa: el Nuevo Modelo de Educación Universitaria que está por construirse, se debe a la crisis del modelo cognitivo instrumental instituido en la Constitución de la República de Venezuela (1961, sus Leyes y Reglamentos. Al triangular las tres categorías se plantea, como valor agregado, concebir la educación a través de un proceso transdisciplinario, sustentado en una primera instancia por el ordenamiento jurídico que le dé concreción y sincronización en el tiempo y el movimiento. En el caso de la educación venezolana, se concluye que no se han producidos cambios significativos que nos indiquen que estamos en presencia de un nuevo modelo de educación. La educación universitaria sigue atada al modelo cognitivo instrumental, impidiendo cualquier cambio que desde su seno se pretenda impulsar, de manera que la nueva Ley de Educación Universitaria y el nuevo modelo de educación siguen diferido.Abstract: This essay is based on an analysis of the higher education in the context socio-political of the Venezuelan reality, in the reference period is 2007-2013, focused the promulgation of the organic law of education (2009.

    The number of cadaveric kidneys available for transplantation has become insufficient around the world. Despite concerted efforts, we have been unsuccessful in greatly improve the supply of organ donors, and consequently the number of end stage renal failure patients awaiting for kidney transplantation continues to increase. The primary objective of this paper is to quantify the need and supply of kidneys for transplant in Venezuela. An overview of the current level of kidney transplant activity in Venezuela is presented, observing that the activity with cadaveric donors had been predominant since 1983, although not to an optimal level. The annual activity in kidney transplant between 1989-1991 remained stable in 6 transplants/million people, but went sharply down to 4.6 in 1992. An estimate of the current need is around 10 donors/million people. This is in contrast with an effective donation rate of only 2.01 and 1.92 donors/million achieved in 1990 and 1991 respectively. The most frequent cause for no donation was the lack of familiar consent. Based on an analysis of the factors involved in the shortage of donor supply in Venezuela, we present some recommendations to increase the availability of cadaveric organ donors in the country. These measures include an improvement of education and legal regulation in the field of organ donation and transplantation, and following the Spanish model, the creation of a program of hospital transplant coordinators that can detect and evaluate potential organ donors as well as coordinate the logistical aspects of transplantation.
