    Full Text Available El trabajo cuestiona los argumentos que justifican la privatización neoliberal de la financiación, gestión y prestación de servicios de salud, y analiza el significado y estrategias de privatización. Comparamos la privatización en Costa Rica y Chile, y en la discusión se sugiere que el modelo costarricense de privatización selectiva, limitada y concebida autóctonamente de Costa Rica lleva a un sistema de salud más solidario, equitativo, eficiente y satisfactorio para los usuarios que el modelo importado de privatización chileno.This study questions the premises that justify the neoliberal privatization of financing, managing and delivering health services. It also analyses the meaning of privatization and its strategies. We compare privatization in Chile and Costa Rica and suggest that the more limited, selective and locally designed privatization process in Costa Rica has resulted in a more equitable, and efficient health system than the imported privatization model introduced in Chile. The Costa Rican system also produces greater patient satisfaction and at the same time preserves the solidarity principle.

    The work of Dr. Claudio Costa Casaretto covers a broad field in the history of Medicine in Chile. He contributed with the historical aspects in the Centennial issue of Revista Médica de Chile in July, 1972. He published 85 papers in this journal in a lapse of 20 years. In his works, he investigated about medical personalities with the highest relevance for Chilean medicine such as Dr. William Blest, graduated in Edinburgh and director of the first Medicine Course in Chile in 1833, the French obstetrician Dr. Lorenzo Sazie, first Dean of the Faculty of Medicine of the University of Chile in 1843 and Dr. Eloisa Díaz, first physician graduated in Chile and South America in 1887. He published the translation from Latin of Juan Ignacio Molina's verses "Elegies to smallpox", Chilean writer and erudite of the XVIII century. He also undertook the origins of Universidad de San Felipe (1737), Universidad de Chile (1842) and Pontificia Universidad Católica de Chile (1889) and the main educational events occurred in the Faculty of Medicine of the University of Chile, during the past century. He also published about the public health situation and sanitary care during the XIX century, about the conflict between private and public teaching and other political events of the past century. The work of Dr. Costa as a whole, is a real history textbook of Chilean Medicine. Dr. Costa and Dr. Enrique Laval are the most important Chilean medical historians of the XX century.

    Full Text Available Mosquito collections were made in and near Costa Marques, Rondonia, Brazil, to determine anopheline anthropophilic/zoophilic behavior. Collections from a non-illuminated, bovine-baited trap and indoor and outdoor human-bait collections were compared. Anopheles darlingi and Anopheles deaneorum were more anthropophilic than the other anophelines collected. The remainder of the Anopheles species were collected much morefrequently in bovine-baited traps than in human-bait collections. Anopheles darlingi and An. deaneorum were more frequently collected inside houses than the other anopheline species. But, when collections were made in a house with numerous openings in the walls, there were few differences in the percentages of each species biting man indoors versus outdoors. Anopheles darlingi was the predominant mosquito collected, both inside and outside houses, and had the strongest anthropophilic feeding behavior of the anophelines present.Para determinar o comportamento antropofilico e zoofilico dos anofelinos, foram capturados mosquitos na periferia e na zona urbana de Costa Marques, Rondônia, Brasil. Foram comparadas as capturas feitas à noite, com iscas bovinas e humanas, dentro efora de casa. O Anopheles darlingi e o Anopheles deaneorumforam mais antropojilicos do que os outros anofelinos capturados. O restante das espécies anofelinas foi capturado mais freqüentemente nas iscas bovinas do que nas humanas. Anopheles darlingi e Anopheles deaneorumforam capturados dentro de casa com mais freqüência do que as outras espécies anofelinas. Porém, quando a captura foi feita em casas com muitas aberturas nas paredes houve pouca diferença nas porcentagens de cada espécie sugadora de humanos dentro efora de casa. Anopheles darlingi foi o mosquito capturado com mais freqüência, dentro e fora de casa, e apresentava maior antropofilia em relação aos outros anofelinos presentes.

    Full Text Available Ganancia genética esperada en Acacia mangium en Los Chiles, zona norte de Costa Rica. Con el objetivo de seleccionar los materiales de mayor crecimiento y calidad de fuste en Acacia mangium, se evaluó un ensayo de progenie de Acacia mangium Willd. conformado por veinticinco familias. El ensayo fue establecido en Los Chiles, zona norte de Costa Rica, en 2006 con evaluaciones en el 2007 y en 2010. Se utilizó material genético seleccionado por la Cooperativa de Conservación y Mejoramiento Genético Forestal "GENFORES", en Costa Rica y Colombia. Cada familia estuvo representada por 48 progenies, plantadas en cuatro parejas distribuidas en forma aleatoria dentro de cada uno de los seis bloques del ensayo. Se evaluó el diámetro a la altura de pecho "DAP", incremento en DAP, adaptabilidad al sitio, número de trozas comerciales, bifurcación, altura de bifurcación, calidad de las primeras cuatro trozas. Se determinó el volumen de madera comercial por árbol y hectárea. Los datos fueron analizados por medio del software SELEGEN de EMBRAPA para obtener los parámetros genéticos. Todos los caracteres registraron valores de heredabilidad media familiar superiores a 0,68. Si se seleccionaran los dos mejores individuos dentro de las mejores doce familias, se obtendría una ganancia genética del 40,8% en volumen comercial/ha a los cuatro años de edad. Esta ganancia corresponde a un volumen comercial de 91,65 m3/ha, a una tasa de 22,9 m3/ha/año. Las dos procedencias derivadas de Colombia son signifi cativamente superiores a los demás materiales evaluados. El análisis de correlación genética entre caracteres muestra que la tasa de crecimiento diamétrico se expresa desde temprana edad en esta especie, lo que podría ser utilizado a futuro en una selección a menor edad.

    The Chilean, Argentinean and Brazilian power matrixes presented in the last two decades a growth of the non-renewable energy sources share, especially fossil sources, mainly in installed capacity and in a lesser degree in energy production. Greenpeace and the European Renewable Energy Council have elaborated a reference energy scenario together with a scenario analyzing the institution of ample measures for the promotion of renewable energy sources. Feed-in tariffs and auction or bidding mechanisms implemented in Brazil and Argentina and the renewable portfolio standard implemented in Chile allied with the wind industry state in these countries indicate that Chile and Argentina will fulfill the 2020 wind power installed capacity predicted in the reference scenarios, while Brazil will reach the energy revolution scenario prediction. Important energy policy changes are required if the Chile and Argentina energy revolution scenarios wind power installed capacity are to become a reality in 2020. (author)

    The present study analyzes educational targeting in Argentina, Brazil and Chile from a sociological point of view. It shows that a `logic of induction' has become the vehicle for anti-poverty education strategies meant to help targeted groups improve on their own. The analysis explores the influence of the global educational agenda, the empirical connection between the logic of induction and the mechanism of emulation, and the territorial aspects of educational inequalities. Emulation plays a main role inasmuch as the logic of induction leads targeted groups to compare their adverse situation with more privileged groups, which actually legitimizes inequalities. A brief statistical summary completes the study, showing that educational inequality has remained unchanged as far as urban-rural ratios (in Brazil and Chile) and regional disparities (in all three countries) are concerned.

    Global governance is of key concern in the current debate over the workings of the world's computer network, and Brazil has played a notable role in this process, especially after approval of the Marco Civil da Internet (law 12.965, april 23, 2014), which defines Brazil's regulatory framework for the internet. Dubbed the internet bill of rights, this law sets out the principles, guarantees, rights, and duties of internet users and providers in Brazil. Based on the fundamental categories of net neutrality, internet users' right to privacy, and copyright discussions from the perspective of intellectual property, the article offers a comparative analysis of regulations in five countries: Brazil, Chile, Spain, the US, and France.

Nuestra estimación encuentra cierta contra-ciclicidad por el lado de las contribuciones, si bien el desembolso de beneficios no tiene efectos significativos. A nivel neto, efectos inflacionarios significativos se cancelan entre sí. Sin duda, mantener un enfoque macroeconómico prudencial también es garantía de bienestar para crecientes números de pensionados y por ello, se hace imperativo fortalecer estos programas como parte de una batería de políticas públicas que no sólo sirvan para eliminar la pobreza entre grupos vulnerables, sino que también aseguren importantes propiedades macroeconómicas no reconocidas.

    Chile is a long (2650 miles), narrow (250 miles at widest point) country sandwiched between the Andes mountains and the Pacific. The northern desert is rich in copper and nitrates; the temperate middle region is agricultural and supports the major cities, including Santiago, the capital, and the port of Valparaiso; and the southern region is a cold and damp area of forests, grasslands, lakes, and fjords. The country is divided into 12 administrative regions. Chile's population of 12.5 million are mainly of Spanish or Indian descent or mestizos. Literacy is 92.3%, and the national language is Spanish. Infant mortality is 18.1/1000, and life expectancy is 68.2 years. 82% of the people are urban, and most are Roman Catholics. Chile was settled by the Spanish in 1541 and attached to the Viceroyalty of Peru. Independence was won in 1818 under the leadership of Bernardo O'Higgins. In the 1880s Chile extended its sovereignty over the Strait of Magellan in the south and areas of southern Peru and Bolivia in the north. An officially parliamentary government, elected by universal suffrage, drifted into oligarchy and finally into a military dictatorship under Carlos Ibanez in 1924. Constitutional government was restored in 1932. The Christian Democratic government of Eduardo Frei (1964-70) inaugurated major reforms, including land redistribution, education, and far-reaching social and economic policies. A Marxist government under Salvador Allende lasted from 1970 to 1973 when the present military government of General Pinochet Ugarte took power, overthrew Allende, abolished the Congress, and banned political parties. It has moved the country in the direction of a free market economy but at the cost of systematic violations of human rights. A new constitution was promulgated in 1981, and congressional elections have been scheduled for October, 1989. A "National Accord for Transition to Full Democracy" was mediated by the Catholic Church in 1985. The social reforms of the

  19. Rights to Land, Forests and Carbon in REDD+: Insights from Mexico, Brazil and Costa Rica

    Directory of Open Access Journals (Sweden)

    Pablo Pacheco

    2011-03-01

    Full Text Available Land tenure and carbon rights constitute critical issues to take into account in achieving emission reductions, ensuring transparent benefit sharing and determining non-permanence (or non-compliance liabilities in the context of REDD+ strategies and projects. This is so because tenure systems influence who becomes involved in efforts to avoid deforestation and improve forest management, and that land tenure, carbon rights and liabilities may be linked or divorced with implications for rural development. This paper explores these issues by looking at tenure regimes and carbon rights issues in Mexico, Brazil and Costa Rica. It is effectively shown that complex bundles of rights over forest resources have distinct implications for REDD+ design and implementation, and that REDD+ strategies in selected countries have to date failed in procedurally addressing land-use conflicts and carbon rights entitlements and liabilities.

  4. Public versus private treatment of chronic diseases in seniors: Argentina, Brazil, Chile and Uruguay.

    Science.gov (United States)

    Cataife, Guido

    2012-01-01

    This article measures differences in the likelihood of treatment of chronic diseases in elders across types of coverage (private, public and social security) in four major Latin American cities: Buenos Aires (Argentina), Sao Paulo (Brazil), Santiago (Chile) and Montevideo (Uruguay). We used a logistic regression to estimate the odds ratio for treatment of chronic diseases carried by individuals with public, private and social security coverage. The data were from the Survey on health, well-being and aging in Latin America and the Caribbean (SABE) conducted in 1999 and 2000. We find a strong association between possession of public coverage only and treatment failure of chronic diseases in elders in Argentina. We find no significant association for Brazil, Chile and Uruguay. In Buenos Aires, access to private or social security coverage is a necessity for elders because the public sector fails to provide proper treatment. In the remaining cities, private or social security coverage provides similar coverage for chronic diseases in elders compared with the public sector. For this group of countries, the main difference between the former and the latter seems to be in terms of 'luxurious' characteristics, such as the quality of the facilities and waiting times.

En costas rocosas existen grandes solapamientos en la composición de las comunidades asociadas a bioingenieros que forman habitats frondosos (algas o mitílidos. Nosotros investigamos la potencial redundancia en la provisión de este tipo de habitat comparando ensambles faunísticos asociados a mantos de Perumytilus purpuratus y frondas de Corallina officinalis var. chilenis, Gelidium chilense y Gastroclonium cylindricum. En tres oportunidades, entre septiembre de 2003 y enero de 2004, muestreamos ensambles de moluscos asociados a cada uno de estos bioingenieros, en alturas de mareas similares en dos áreas rocosas de Chile central. De las 31 especies de moluscos identificados, 30 fueron encontrados en Corallina y 19-22 fueron identificados en los otros habitat. El conjunto de especies asociado a cada bioingeniero se sobrepone ampliamente, demostrando el potencial de redundancia en la provisión de habitat y poca especificidad de habitat. Sin embargo, análisis multivariados y univariados mostraron que los bioingenieros, con excepción de Gastroclonium, contenían un ensamble de moluscos único en al menos uno de los periodos de muestreo, ya sea en la variación en la frecuencia de ocurrencia, riqueza y abundancia total. Estudios recientes han destacado diversos procesos antropogénicos y naturales que influencian directamente la diversidad y composición de especies en bioingenieros de costas rocosas. Se demuestra que para la costa de Chile central la pérdida de cualquier de los bioingenieros analizados no alteraría sustancialmente el conjunto total de especies de moluscos, alojados en ellos. Sin embargo, la pérdida de cualquier bioingeniero, excepto Gastroclonium, resultaría en una disminución local de la biodiversidad debido a que cada uno de los ensambles de moluscos en Perumytilus, Corallina y Gelidium, contiene una estructura comunitaria significativamente diferente, en al menos

  10. Acceptability of emergency contraception in Brazil, Chile, and Mexico. 2 - Facilitating factors versus obstacles

    Directory of Open Access Journals (Sweden)

    Soledad Díaz

    Full Text Available A multi-center study was performed in Brazil, Chile, and Mexico to identify factors that may facilitate or hinder the introduction of emergency contraception (EC as well as perceptions concerning emergency contraceptive pills. Background information on the socio-cultural, political, and legal context and the characteristics of reproductive health services was collected. The opinions of potential users and providers were obtained through discussion groups, and those of authorities and policymakers through semi-structured interviews. Barriers to introduction included: perception of EC as an abortifacient, opposition by the Catholic Church, limited recognition of sexual and reproductive rights, limited sex education, and insensitivity to gender issues. Facilitating factors were: perception of EC as a method that would prevent abortion and pregnancy among adolescents and rape victims; interest in the method shown by potential users as well as by some providers and authorities. It appears possible to reduce barriers through support from segments of society committed to improving sexual and reproductive health and adequate training of health care providers.

Several interviewees felt that all women should be informed about EC, while others viewed it as a method for special situations such as rape and unprotected first sexual intercourse. Concern was expressed that its introduction might be associated with a decrease in condom use, increase in sexually transmitted diseases, and irresponsible or promiscuous sexual behavior among adolescents. The need for EC was clearly perceived by most participants, leading to the conclusion that health authorities have the responsibility of implementing programs for its introduction. Training of health care personnel should include the discussion of reproductive health problems that could be prevented by EC.

    Full Text Available Aprovechando la reconstrucción del índice de posición latitudinal del anticiclón del O.Pacífico Sur sobre la costa de Chile (L durante el período 1901-2004, se analiza su comportamiento de largo plazo como variable anual o mensual en el período más precipitante del clima mediterráneo sudamericano. Existe una importante evidencia del traslado de L hacia latitudes altas desde mediados del Siglo XX al presente, que podría ser justificado con el actual proceso de calentamiento global, sin embargo esto no parece justificar el comportamiento opuesto observado en la primer mitad del Siglo XX. En términos mensuales la tendencia hacia latitudes altas es más evidente en L, pero el mes de Junio (opuesto es el encargado de mostrar que fluctuaciones de media y alta frecuencia pueden torcer una tendencia larga, lo que no hace recomendable el análisis en esta escala. Esto también es válido para series de variables anuales de alrededor de medio siglo o menos. Otra variable importante para el análisis en esta ocasión fue la intensidad anual del flujo de los Oeste en latitudes altas, que sí parece tener un comportamiento tendencial acorde a los cambios del calentamiento global.

    Full Text Available Cryptobia neghmei sp.n. is described from the blood of two species of flounder, Paralichthys microps and P. adspersus, inhabiting the Chilean coast in the southern Pacific Ocean. Flagellates were elongate, slender, with two flagella and a conspicuous undulating membrane. It was distinguished from previously described species on the basis of its unusual shape and dimensions. All of 97 flounder were infected upon examination. Developmental stages of kinetoplastid protozoans, perhaps C. neghmei sp. n., were observed in some leeches Glyptonotobdella sp. that were found attached to flounder, which probably represent a mode for transmission among piscine hostsSe describe a Cryptobia neghmei sp.n., un protozoo sanguíneo de dos especies de lenguados, Paralichthys microps y P. adspersus, habitantes de la costa de Chile en el sur-este del océano Pacífico.

Since artificial and natural floating substrata are also abundant at high latitudes it is inferred that the low diversity of littoral caprellids at high latitudes is not due to lack of dispersal vectors, but rather of other factorsMuchas especies de caprélidos del litoral presentan una amplia distribución, algunas han sido citadas a lo largo de todo el mundo. La distribución cosmopolita de muchas especies de caprélidos podría deberse al hecho de que se asocian frecuentemente a las comunidades "fouling" en objetos flotantes, que presentan una capacidad importante de dispersión a largas distancias. Esta capacidad de dispersión puede tener implicaciones en la distribución de caprélidos a escala local y regional. En este estudio, nosotros examinamos la distribución de las especies de caprélidos litorales en dos escalas espaciales, local (decenas de kilómetros y regional (cientos de kilómetros, a lo largo de la costa Pacífico de Chile continental. A escala local se estudió la fauna de caprélidos en distintos hábitats (bolones intermareales, praderas de algas y fanerógamas marinas, comunidades "fouling" de boyas y cuerdas; a escala regional el estudio se centró solamente en los caprélidos asociados a boyas y cuerdas. Se encontraron un total de seis especies de caprélidos, algunos de los cuales fueron muy abundantes a escala local y regional. A escala local, existió una diferencia entre los tres tipos de hábitat con respecto a la fauna de caprélidos, algunos de los cuales estuvieron presentes en más de un hábitat. Los valores más altos de riqueza específica y abundancia se encontraron en la comunidad "fouling" asociada a boyas y cuerdas ancladas. A escala regional, los caprélidos fueron más abundantes y diversos en las comunidades "fouling" de la región norte

    Full Text Available El rol e impacto de los herbívoros en la trama trófica de comunidades intermareales rocosas podría ser más diverso y complejo de lo considerado hasta ahora, particularmente en el caso de consumidores de mayor tamaño y abundancia como el erizo negro Tetrapygus niger (Molina en la costa de Chile. En este contexto, analizamos la variación en riqueza y composición de la dieta de T. niger en cuatro comunidades intermareales rocosas del norte de Chile, distribuidas en 1.000 km de costa, y muestreadas estacionalmente entre invierno 2004 y primavera 2005. Durante el estudio ocurrió el evento El Niño 2004-2005 cuyo efecto potencial fue incorporado en esta evaluación. En cada comunidad y estación se evaluó la abundancia de las especies presentes en 45 cuadrantes (0,25 m² distribuidos en cinco bloques permanentes, recolectando cerca de 10 individuos de T. niger a los que se midió su biomasa y longitud, determinando el número, identidad y frecuencia de ocurrencia de ítemes en su contenido gástrico. Colectamos un total de 251 individuos de T. niger, que en conjunto consumieron 89 ítemes de algas (64 % e invertebrados (36 %; incluyendo otros herbívoros. Una relación inversa significativa entre el tamaño corporal y el número de ítemes animales ingeridos sugiere que T. niger varía su dieta durante la ontogenia. La amplitud de nicho dietario fue alta y tendió a disminuir hacia latitudes menores. Globalmente, el espectro y frecuencia de ocurrencia de ítemes dietarios no fueron significativamente distintos entre comunidades, pese a marcadas diferencias en intensidad de surgencia entre ellas. Similarmente, no hubo relación clara entre la oferta ambiental de recursos y su frecuencia en la dieta de T. niger, destacando la clorófita Ulva rígida que fue el ítem consumido con más frecuencia en cada comunidad pero no el más abundante en terreno. Sin embargo, la riqueza dietaria de T. niger se relacionó negativa y significativamente con la

    Full Text Available El tunicado Pyura chilensis se ha considerado una especie de importancia ecológica, por concentrar una gran diversidad biológica en sus agregaciones y de importancia económica por ser un recurso de extracción por pescadores artesanales. Sin embargo, se han detectado cambios en la distribución y abundancia de sus poblaciones adjudicados a su sobreexplotación. Para llegar a establecer medidas de conservación de un recurso, es necesario entre otras cosas, conocer su variabilidad genética y su estructura poblacional, estimando los patrones y sus causas. Por lo tanto, en el presente trabajo se determinó el grado de variabilidad genética aloenzimática del piure P. chilensis y su estructura poblacional en base a tres localidades (Antofagasta, Talcahuano y Puerto Montt en la costa chilena. Los loci polimórficos obtenidos fueron Mdh-1 y Pgi-1. Los valores de Fst mostraron leve estructuración poblacional entre localidades (Fst 0,019 al igual que la prueba exacta de diferenciación genética (P = 0,031. Se observó diferenciación para la localidad de Puerto Montt en relación a las otras dos localidades en algunos de los dos loci. Los niveles de variabilidad observados en esta especie corresponden a lo esperados para otras ascidias. La estructuración genética poblacional puede ser explicada por una combinación de diferentes factores, entre los que destacan: (i el tiempo del periodo larval de 12 a 24 h, lo cual no facilitaría una amplia dispersión a lo largo de 2.500 km de costa y (ii las condiciones oceanográficas diferenciales entre localidades, junto a patrones de circulación cerrados que podrían llegar a restringir el flujo génico. Por último, proponemos que un conocimiento adecuado del grado de variabilidad, estructura y dinámica genética de las poblaciones son aspectos esenciales para tomar medidas de conservación de recursos explotados, tanto en ambientes abiertos como en áreas de manejoThe ascidian Pyura chilensis is an

    Full Text Available Los caprélidos son comunes y abundantes en muchos hábitats litorales del ambiente marino. Sin embargo este grupo de anfípodos no ha sido muy bien estudiado en la costa chilena. El estudio de los caprélidos se ha visto dificultado por su gran variabilidad morfológica y el hecho de que la literatura así como los especímenes de los museos son difíciles de localizar. El objetivo de este estudio fue entregar las herramientas taxonómicas para la identificación de las especies de crustáceos caprélidos comunes en el centro-norte de la costa de Chile. Se muestrearon distintos hábitats (boyas, bolones intermareales, praderas de algas y fanerógamas marinas y se encontraron seis especies distintas de caprélidos: Caprellina longicollis (Nicolet, 1849, Caprella equilibra Say, 1818, C. scaura Templeton, 1836, C. verrucosa Boeck, 1871; Deutella venenosa Mayer, 1890 y Paracaprella pusilla Mayer, 1890. Caprella scaura, C. verrucosa y D. venenosa fueron muy abundantes sobre las algas, hidrozoos y briozoos asociados a boyas. Caprella equilibra, también presente en boyas, fue más abundante bajo piedras en zonas intermareales rocosas expuestas, donde también se encontraron ejemplares de D. venenosa y de P. pusilla. Caprella scaura también se encontró sobre algas rojas de las playas arenosas, especialmente sobre Gracilaria chilensis y sobre la fanerógama marina Heterozostera tasmanica, donde cohabitó junto a Caprellina longicollis. Paracaprella pusilla constituye una nueva cita para las costas pacíficas sudamericanas, siendo nueva para la fauna de Chile. La especie D. venenosa, que se cita por primera vez después de la descripción original de Mayer en el año 1890, es considerada una especie endémica de la costa central de ChileCaprellids are abundant in many littoral habitats of the marine environment.

    en invertebrados marinos a escalas espaciales grandes es de vital importancia para determinar las variables ambientales críticas que afectan la reproducción, y así poder entender los patrones espaciales de las dinámicas poblacionales. Sin embargo, la información sobre patrones de reproducción en invertebrados marinos a gran escala es escasa, y en algunos casos ha sido generada tomando en cuenta especies con diferentes modos de desarrollo. Los crustáceos braquiuros son un grupo de gran interés para analizar patrones de reproducción a gran escala no solo por la importancia comercial de muchas especies sino también por presentar un único modo de desarrollo larval y un amplio rango de distribución geográfica. En este trabajo reportamos los patrones reproductivos de cinco especies de braquiuros: Cancer setosus, Paraxanthus barbiger, Homalaspis plana, Ovalipes trimaculatus y Taliepus marginatus, a lo largo de la costa de Chile (18-54 ° S. Cinco variables fueron analizadas: peso de la masa de embriones, fecundidad, peso seco del embrión, volumen del embrión y pérdida de embriones. Se realizaron comparaciones entre el norte (20 ° S, centro (29-33 ° S y sur de Chile (35-41 ° S para C. setosus, y entre el centro y sur de Chile para las otras cuatro especies. Se recolectaron y analizaron un total de 378 hembras ovígeras. Aunque no detectamos un patrón bien definido para todas las variables reproductivas en las especies analizadas a lo largo de la costa de Chile, emergieron al menos tres generalidades. Primero, en la mayoría de las especies el peso de la masa de embriones no varió entre el centro y sur de Chile (exceptuando P. barbiger. Segundo, la pérdida de embriones no varió entre el centro y sur de Chile en cuatro de las especies estudiadas. Tercero, el peso seco del embrión tendió a aumentar en poblaciones de latitudes altas en cuatro de las especies analizadas.

    Abstract New members of the spider family Caponiidae from Brazil and Chile are presented. Three new species in previously known genera are described: Taintnops paposo sp. n. from Chile, and the Brazilian Tisentnops mineiro sp. n. and Tisentnops onix sp. n., both belonging to a genus known only from its damaged type. Additionally, two new non–nopine Brazilian genera are proposed: Nasutonops gen. n. including three new species: Nasutonops chapeu sp. n., Nasutonops sincora sp. n. and Nasutonops xaxado sp. n.; and Carajas gen. n., known only from the type species Carajas paraua sp. n. Both new genera have entire, rather than sub-segmented tarsi. Therefore, they are not included in the caponiid subfamily Nopinae.

    Full Text Available New members of the spider family Caponiidae from Brazil and Chile are presented. Three new species in previously known genera are described: Taintnops paposo sp. n. from Chile, and the Brazilian Tisentnops mineiro sp. n. and Tisentnops onix sp. n., both belonging to a genus known only from its damaged type. Additionally, two new non–nopine Brazilian genera are proposed: Nasutonops gen. n. including three new species: N. chapeu sp. n., N. sincora sp. n. and N. xaxado sp. n.; and Carajas gen. n., known only from the type species C. paraua sp. n. Both new genera have entire, rather than sub-segmented tarsi. Therefore, they are not included in the caponiid subfamily Nopinae. Nasutonops gen. n. is characterized by the presence of a projected clypeal horn, unique among caponiids. Additionally, the first blind caponiids are described: Tisentnops mineiro sp. n. from the state of Minas Gerais and Carajas paraua sp. n. from the state of Pará. Both of these species are found only in caves and completely lack eyes.

    The best way to preserve chile depends on how you plan to use it and your available storage space. Frozen or canned chile is best for chile rellenos and salsas. Stews can use frozen, canned or dried chile. Dried chile has minimal storage requirements and is light-weight for taking on camping trips. Pickled chiles can be used on a relish plate or as an ingredient in other dishes.

En primer lugar, se reconstruyen los principales debates de la CEPAL de los tempranos años cincuenta y su repercusión en los distintos proyectos y alternativas políticas de la época. En segundo lugar, se analiza cómo el triunfo de la Revolución Cubana obligó a revisar esos mismos problemas latinoamericanos, abriendo un nuevo escenario de alternativas políticas para las izquierdas y para las derechas. El estudio propone reubicar "revolución" y "violencia", tópicos muy propios de la década de 1960, en un mapa integral de circulación de ideas que comenzó a conformarse en la coyuntura crítica de los 1950.This paper intends to analyze the relationship between politics, ideas and beliefs in Argentina, Brazil, Chile and Uruguay during the period 1950-1960. First, we reconstruct the main debates at CEPAL in the early 1950s and their repercussion on the distinct projects and political alternatives at that time. Second, we analyze how the success of the Cuban Revolution made it necessary to revise these same problems in Latin America, opening the door to a new scenario of political alternatives for the left- and right-wing. The study proposes reconsidering the position of "revolution" and "violence", topics that were highly characteristic of the 1960s, on an integral map of ideas that began to take shape in the critical instance of the 1950s.

    This work describes the experience of four Latin American countries in the area of energy efficiency (EE), with particular emphasis on the creation and effectiveness of institutional systems needed to develop policies, programs and mechanisms to promote EE. The wide variety of situations presented in the study of national cases in Brazil, Chile, Mexico and Uruguay, as well as the wealth of their experiences may provide significant contributions to the promotion of EE in the region. Brazil stands out because of its long and rich history in the field of promoting EE, in particular, for work conducted in 1985 by PORCEL, a federal program with its base of operations at ELETROBRAS, which served as the national coordinator of EE activities in the electric sector during a large part of the period and was responsible for the successful implementation of activities to foster EE in various areas. While PROCEL and CONPET continue to fulfill an important role, other actors have become involved over time in the activities related to EE, with a gradual transfer over recent years of the activities of these programs to the primary agencies in the sector, particularly MME, ANEEL, ANP and EPE. Currently, Brazil has an extensive network of public and private institutions involved in the area of EE, as well as norms that encourage EE with sufficient resources and regulatory mechanisms to finance and guide these activities. Although a large variety of initiatives have been implemented, they do not yet constitute a national EE policy. Thus, the need is seen for greater institutional coordination that allows for improving the convergence of results, utilizing economies of scale and creating opportunities to develop a national EE policy. Along the lines of the perspective described, the development is underway of a National Energy Efficiency Plan (PNEf, Spanish acronym), coordinated by the MME, that should include the basic elements needed to define an EE policy.

    This discussion of Costa Rica focuses on: geography, people and history, government, political conditions, the economy, defense, foreign relations, and relations between the US and Costa Rica. In 1985 the population totaled 2.6 million with an annual growth rate of 2.6%. The infant mortality rate is 15.2/1000; life expectancy is 67.5 years for men and 71.9 years for women. Costa Rica, the 2nd smallest Central American country, is located in a narrow strip between Panama and Nicaragua. Costa Ricans are overwhelmingly of European descent. Although preominantly Spanish, there also are many Costa Ricans of German, Dutch, and Swiss origin. The indigenous Indian population numbers about 20,000, 20% fewer than inhabited Costa Rica when the Spanish first settled in 1522. Blacks, descendants of 19th century Jamaican immigrant workers, constitute a significant English-speaking minority of 30,000. Costa Rica is a democratic republic with a strong systems of checks and balances. The president and 57 legislative assembly deputies are elected for 4-year terms. Costa Rica's political system has contrasted with that of its neighbors. The nation has steadily developed and maintained democratic institutions and an orderly, constitutional process of government succession. Costa Rica faces severe challenges to its economic stability, although traditionally it is one of the strongest nations in the region. Increases in government spending in the late 1970s and higher world prices for coffee and other important Costa Rican exports stimulated the economy, creating inflationary pressure. The government is pursuing a course of disciplined management. The country is an outsponken and active member of the international community. The cordial relationship between Costa Rica and the US is based on mutual respect for democratic traditions, common goals, and a relationship free from serious political disagreement.

De acuerdo a Darwin (1859, en general, estas "islas" corresponderían a los remanentes de poblaciones glaciales, que ocuparon sitios de menor altitud y latitudes más bajas, durante el avance de los hielos. Se desprende de esta hipótesis que, a lo largo de Chile, se habrían producido desplazamientos de la flora austral y andina hacia el Valle Longitudinal, durante la última glaciación, y en sentido inverso, durante el Tardiglacial (14.600-10.000 14C años AP y Holoceno (después de 10.000 14C años AP. Considerando esta hipótesis, en este trabajo se analizan dos secuencias palinológicas, procedentes de las cimas de la Cordillera de la Costa de la Región de los Lagos (cordilleras de Nahuelbuta y de Sarao, y se correlacionan con registros publicados, tanto de otros sitios de cimas de cerros, como de sitios de baja altitud, todos ellos procedentes de las regiones de Los Lagos y de Los Canales. Los registros de las cimas de la Cordillera de La Costa, analizados en este estudio, muestran la siguiente secuencia cronológica: (1 El registro de la Cordillera de Sarao documenta, para el Holoceno temprano, a partir de 9.040 14C años AP, la colonización del elemento de tundras magallánicas y bosque norpatagónico con coníferas, aunque ambas formaciones alcanzan su máximo desarrollo en el Holoceno medio, sucedidas por el elemento de bosque norpatagónico-valdiviano, en el Holoceno tardío.

    Full Text Available The Cerro de la Campana range, in the central part of Chile, is described. The area has several important features, and parts of it have been declared as National Park. Besides the high taxonomic and ecology diversity, both in animals and in plants, it has the southernmost forests of palm trees, as well as many other subtropical residual forests. Many species reach here the extreme south limit. But the ecosystems of the area are endangered and most of them have been decreasing or even vanishing in the past because of the human pressure. The main dangers come from fire and from slash cutting, although many natural communities there seem to be adapted to periodic burns. The consequences of these dangers and some protective measures are discussed.

    Se describe la cadena del Cerro de la Campana, cuyos recursos naturales han determinado la creación en la zona de un Parque Nacional. Los aspectos más interesantes de la zona se relacionan con la existencia en la misma de bosques subtropicales relictos, así como de bosquetes de palmeras en los que la familia palmáceas alcanza su límite extremo meridional. Por otra parte, la variedad ecológica del área es muy elevada, al igual que su riqueza específica, puesto que alberga 7tiuverosas especies de vertebrados, invertebrados y plantas. Muchas especies encuentran aquí su límite meridional absoluto. Sin embargo la zona se encuentra amenazada por la presión humana, especialmente en la forma de incendios forestales y tala masiva, a pesar de que muchas comunidades naturales parecen estar adaptadas a los incendios repetidos. En el trabajo se analizan las consecuencias de estas amenazas y se sugieren medidas encaminadas a la protección del paraje.

    Full Text Available The coral reef is an ecossystem which evokes great interest, for its beaury, species diversity and fisheries potential. The coast of Paraíba State, northeast Brazil, possesses several natural reefs and shipwrecks which are inhabited by a rich fish fauna. In order to survey the reef fish fauna of Paraíba State, a total of 118 dives, utilizing SCUBA diving techniques, were carriedoutin 27samplingpoints (depths: 0,5-66m, from February/1995 to May/1996. Specimens were collected whenever underwater identification was precluded. A total of 157 known species belonging to 59 families were found. Four unidentified species, one dasyatid, one haemulid, one scarid, and one labrid were recorded. Haemulidae was the most representative family in number of individuais, whereas Carangidae was the most speciose family. This paper is part of a broader study of the northeast Brazilian reef fishes.

Se estimó la tasa de crecimiento promedio para cada año, desde 1972 a 2009 y se analizaron los parámetros y curvas de crecimiento de vB, agrupados en tres periodos, seleccionados en referencia a importantes variaciones en la biomasa del stock, a saber: 1972-1990, 1991-2003 y 2004-2009. Los resultados indicaron que la tasa de crecimiento promedio mostró variaciones interanuales que no superan ± 1,5 cm LT en torno al promedio histórico de machos y hembras, no mostrando una tendencia persistente hacia el aumento o disminución sostenida. Las curvas de crecimiento obtenidas con los parámetros (vB estimados para los tres periodos indicados, mostraron tanto en hembras como en machos, trayectorias similares hasta los 7 y 8 años de edad, respectivamente. Variaciones posteriores a estas edades se podrían deber a la disminución de los peces de mayor tamaño en la distribución, removidos por el efecto selectivo de la pesca que efectivamente ocasiona variaciones en las curvas ajustadas, pero estas variaciones no son el reflejo de cambios en el crecimiento somático de esas edades en la población. Los resultados permiten concluir que el crecimiento somático de merluza común no ha variado en forma importante desde 1972, los cambios que se observan en peces de mayor edad es probable que obedezcan a causas distintas a la denso-dependencia.

    Full Text Available Polyplacophorans are common herbivores on rocky shores, but basic aspects of their ecology remain scarcely studied and their role within communities could be more complex than previously considered. Such is the case of Acanthopleura echinata (Barnes, one of the largest and most conspicuous chitons in the world, and at the same time, one of the least known intertidal species in the southeastern Pacific. To improve the basic ecological knowledge of this potentially important intertidal consumer, we studied the diet of A. echinata and its variation among sites of varying levels of coastal upwelling spread over 1000 km along the coast of northern Chile. A seasonal evaluation of diet, body size distribution and density at sites expected to vary in overall nutrient loadings, benthic algal productivity and sea surface temperature, allowed us to examine plasticity in Acantholeura diet and body size. Overall, A. echinata consumed 85 items of algae (64.7 %, mainly fleshy and calcified encrusting thalli and invertebrates (35.3 %, mainly barnacles. Diet was always dominated by encrusting corallines, although the proportion of algae increased with body size suggesting an ontogenetic variation in feeding habits. Although the number and occurrence frequency of dietary items varied significantly in time and space, there were no consistent seasonal patterns and the dominant items in the diet remained the same at all places. The density of A. echinata showed no significant spatial variation, but its body size and diet breadth correlated positively among sites and both tended to increase with latitude. Our results show that A. echinata is a generalist, polyphagous consumer with a high potential for affecting the space-occupancy dynamics in the intertidal system, and also that among site variation in diet bears no simple relationship with variation in sea surface temperature and upwelling intensity.Los poliplacóforos son herbívoros comunes en costas rocosas, pero

En este estudio se evaluaron siete rodales de la cordillera de la Costa, en la parte norte de la distribución del tipo forestal (39°14'-40°16' S. En ellos se midió la densidad de árboles, plántulas y brinzales, y se estimó la cobertura de copas de los árboles así como del sotobosque, con la finalidad de evaluar los efectos de la dominancia, la estructura y la cobertura del sotobosque sobre la densidad de plántulas de especies forestales. Laurelia philippiana fue la especie dominante a nivel arbóreo y de plántulas. El número de plántulas fue en general significativamente más abundante a altitudes menores donde Aextoxicon punctatum fue importante. Chusquea spp. y Lophosoria quadripinnata, ambas especies del sotobosque, tuvieron un efecto negativo significativo en la densidad de plántulas. El área basal y la cobertura de copas mostraron una pobre relación con la densidad de plántulas. La estructura vertical, evaluada a través del índice de copas, tuvo una relación significativa con la densidad de plántulas, pero su dirección dependió de la especie (i.e., L. philippiana y A. punctatum y la estructura de diámetros de las parcelas. Los modelos ajustados con estas variables fueron altamente significativos, y en la mayoría de los casos su significancia aumentó considerablemente (14 a 26 % cuando se ajustaron separadamente para parcelas con distintas estructuras diamétricas

    Full Text Available The onshore distribution and abundance of the South American sea lion Otaria flavescens along the central Chilean coast was estimated during the period January-February 2007. Additionally, changes in population abundance during the period 1970-2007 were examined. Population surveys were based on photographs taken from boats or aircraft. A total of 16301 sea lions (CI = 16209-16375 were counted in 33 colonies (6 breeding and 27 non-breeding sites. After correction to account for the proportion of individuals at sea and for pups not seen at the time of the survey, the mean estimated abundance was 18179 (95 % CI = 17777-18851 sea lions. Population trend analysis showed that from 1970 to 1985, South American sea lions showed a positive increase of approximately 2.1 % yr-1. Nevertheless, between 1985 and 1997 and between 1997 and 2007, the estimated number of sea lions showed a stable or slightly negative trend of 0.4 ± 0.1 % yr-1and 0.5 ± 0.1 % yr-1, respectively. We suggest that the overexploitation and decline of the principal fisheries in Central Chile could adversely impact the abundance and distribution of the South American sea lion in the study area.Se estimó la distribución y la abundancia poblacional del lobo marino común Otaria flavescens en la costa de Chile central durante los meses de enero y febrero de 2007.

    Echinococcus granulosus is a taeniid cestode and the etiological agent of an infectious zoonotic disease known as cystic echinococcosis (CE) or hydatid disease. CE is a serious public health concern in many parts of the world, including the Americas, where it is highly endemic in many regions. Echinococcus granulosus displays high intraspecific genetic variability and is divided into multiple genotypes (G1-G8, G10) with differences in their biology and etiology. Of these, genotype G1 is responsible for the majority of human and livestock infections and has the broadest host spectrum. However, despite the high significance to the public and livestock health, the data on genetic variability and regional genetic differences of genotype G1 in America are scarce. The aim of this study was to evaluate the genetic variability and phylogeography of G1 in several countries in America by sequencing a large portion of the mitochondrial genome. We analysed 8279bp of mtDNA for 52 E. granulosus G1 samples from sheep, cattle and pigs collected in Argentina, Brazil, Chile and Mexico, covering majority of countries in the Americas where G1 has been reported. The phylogenetic network revealed 29 haplotypes and a high haplotype diversity (Hd=0.903). The absence of phylogeographic segregation between different regions in America suggests the importance of animal transportation in shaping the genetic structure of E. granulosus G1. In addition, our study revealed many highly divergent haplotypes, indicating a long and complex evolutionary history of E. granulosus G1 in the Americas.

    Full Text Available One event of three consecutive days and another of four consecutive days of Stratus clouds were registered at the Maceio airport on the northeast coast of Brazil. This is a very rare phenomenon for equatorial regions and it was analyzed using the high resolution (10km ETA model, NCEP reanalysis, satellite data and conventional data supplied by the Hydrometeorological Directory DHM-SERHI/AL and by the Department of Flight Protection of the Zumbi dos Palmares airport. Wave disturbance in the trade winds and weak ascendant movements at low levels (1000 and 925hPa were identified. At the same time, anticyclonic curvature at high levels formed descendant movements and subsidence inversion. These vertical movements combined with a stable layer between 850 and 700hPa created a very humid layer at the low levels. The precipitation forecasted by the ETA model with 24h antecedence presented a satisfactory result for an average quantity of precipitation. Nevertheless, the spatial distributions of forecasted and observed precipitation were different. Precipitation during all days was not forecasted for the coastal region, and for the west region the forecasted precipitation was more intense than the observed ones.Foram registrados dois eventos de três e quatro dias consecutivos de nuvens Stratus no aeroporto de Maceió na costa leste do Nordeste Brasileiro (NEB.

    This work describes the experience of four Latin American countries in the area of energy efficiency (EE), with particular emphasis on the creation and effectiveness of institutional systems needed to develop policies, programs and mechanisms to promote EE. The wide variety of situations presented in the study of national cases in Brazil, Chile, Mexico and Uruguay, as well as the wealth of their experiences may provide significant contributions to the promotion of EE in the region. Brazil stands out because of its long and rich history in the field of promoting EE, in particular, for work conducted in 1985 by PORCEL, a federal program with its base of operations at ELETROBRAS, which served as the national coordinator of EE activities in the electric sector during a large part of the period and was responsible for the successful implementation of activities to foster EE in various areas. While PROCEL and CONPET continue to fulfill an important role, other actors have become involved over time in the activities related to EE, with a gradual transfer over recent years of the activities of these programs to the primary agencies in the sector, particularly MME, ANEEL, ANP and EPE. Currently, Brazil has an extensive network of public and private institutions involved in the area of EE, as well as norms that encourage EE with sufficient resources and regulatory mechanisms to finance and guide these activities. Although a large variety of initiatives have been implemented, they do not yet constitute a national EE policy. Thus, the need is seen for greater institutional coordination that allows for improving the convergence of results, utilizing economies of scale and creating opportunities to develop a national EE policy. Along the lines of the perspective described, the development is underway of a National Energy Efficiency Plan (PNEf, Spanish acronym), coordinated by the MME, that should include the basic elements needed to define an EE policy.

The opinion scale for mental disorders was applied. The results showed statistically significant differences (5% in terms of authoritarianism, mental hygiene ideology, serial restriction and minority vision, which were favorable to Brazilian students. As to the factor interpersonal etiology, the results were favorable to Peruvians, while the results for etiology of mental strain were favorable to Chileans. There was no statistical evidence to confirm any difference in terms of benevolence. These results reveal that Brazilian students present more positive attitudes towards mental disorders, as they showed to be less authoritarian, restrictive and discriminative than the Chilean and Peruvian students. Therefore, they are more likely to develop a more therapeutic behavior towards people with mental disorders.

    Brazil's population in 1985 was 135 million, with an annual growth rate (1982) of 2.3%. The infant mortality rate (1981) was 92/1000, and life expectancy stood at 62.8 years. 76% of the adult population was literate. Brazil is a federal republic which recognizes 5 political parties. 55% of the population is Portuguese, Italian, German, Japanese, African, or American Indian; 38% is white. Of the work force of 50 million, 35% are engaged in agriculture, 25% work in industry, and 40% are employed in services. Trade union membership totals 6 million. The agricultural sector accounts for 12% of the GDP and 40% of exports. Brazil is largely self-sufficient in terms of food. The GDP was US$218 billion in 1984, with an annual growth rate of 4%. Per capita GDP was US$1645. Brazil's power, transportation, and communications systems have improved greatly in recent years, providing a base for economic development. High inflation rates have been a persistent problem.

    Central America is recognized as a mega diverse "hot-spot" and one of its smaller countries, Costa Rica, as one of the world's leaders in the study and conservation of tropical biodiversity. For this study, inspired by the 60th anniversary of the journal Revista de Biología Tropical, we tabulated all the scientific production on Costa Rican biodiversity published in Revista de Biología Tropical between 2000 and 2010. Most articles are zoological (62%) and 67% of authors had only one publication in the jounal within that period. A 54% of articles were published in English and 46% in Spanish. A 41% of articles were written in collaboration among Costa Rican institutions and 36% in collaboration with foreign institutions. The Collaboration Index was 2.53 signatures per article. Visibility in American sources was 56% in Google Scholar and 42.66% in the Web of Science, but the real visibility and impact are unknown because these sources exclude the majority of tropical journals. Revista de Biología Tropical is the main output channel for Costa Rican biology and despite its small size, Costa Rica occupies the 10th. place in productivity among Latin American countries, with productivity and impact levels that compare favorably with larger countries such as Brazil, Mexico, Argentina and Chile.

The results of the current study were: 11.4% maternal transfer rate; 2.2% cesarean sections; 1.2% neonatal ICU admissions; and 1% 5-minute Apgar scores below 7. Delivery dystocia and the request for epidural anesthesia were the main reasons for maternal transfer, and respiratory distress was the main cause of neonatal ICU admission. Corrected neonatal mortality was 2 per 1,000 live births. The results at this birthing center did not differ significantly from those in a review of the international literature. The most striking finding was the low cesarean rate. Comparative studies and more comprehensive national data on low-risk gestations are needed.

    Full Text Available Cheilodactylus variegatus is an abundant carnivorous demersal reef fish that lives in the shallow subtidal of the north-central Chilean coast. Characteristically, these environments are dominated by kelp forests of Lessonia trabeculata. This species preys on a great variety of benthic invertebrates, and shows particularly high consumption rates on amphipod crustaceans. In our study, two widely separated populations of C. variegatus were considered (central and northern Chile. Individuals that form part of these populations show considerable differences in their distribution, abundance and trophic behavior. In the northern zone, the species is abundant and both juveniles and adults are distributed along the whole bathymetric gradient. This contrasts with populations found in central Chile, which are more sparse and lack juveniles. The distribution and abundance patterns appear to be influenced mainly by the great abundance of diverse understory macroalgae in the northern subtidal, which harbors a large number of invertebrates, especially amphipods. In contrast, the understory algal abundance of the central zone is much lower, and does not show a direct relationship with the lesser abundance of amphipods. In general, C. variegatus maintains a high consumption rate on amphipods throughout its ontogeny but it includes several other prey items in later ontogenetic stages. The different understory algal assemblages, and their associated fauna, are likely to be the main factors influencing the patterns of abundance and distribution observed between these two geographically distinct fish populationsCheilodactylus variegatus es un pez demersal abundante que habita el submareal somero de la costa norte y central de Chile.

    Full Text Available In this paper we bring together institutional, contextual, and behavioral perspectives in a comprehensive model that explores determinants of executive and legislative approval based on economic performance in Brazil and Chile. Our main question is, do voters attribute responsibility for the state of the economy to their representatives in the Legislative Branch as they apparently do to officeholders in the Executive Branch? We search for answers to this question with an eye on how active the distinct branches of government are in economic policy-making and voters’ levels of political sophistication. Our main hypothesis is that less sophisticated voters will blame politicians indiscriminately for the state of the economy, independent of how influential each branch of government is on economic policy. More sophisticated voters will better discern the role each branch plays in economic policy-making and will not blame representatives in the Legislative Branch for the state of the economy when Congress is not active in economic policy-making. The cases of Brazil and Chile under Cardoso and Lagos offer the perfect opportunity to test this hypothesis, which is confirmed by our data.

No obstante, en Chile y a nivel mundial existen pocos estudios parasitológicos sobre crustáceos que habitan el intermareal rocoso. En este estudio se registró y comparó la carga parasitaria de crustáceos decápodos, y se relacionó con la abundancia de sus hospedadores definitivos (peces y aves. Entre julio y septiembre de 2013 se recolectaron 409 crustáceos, correspondientes a 16 especies, desde el intermareal rocoso de dos localidades de Chile central (33°S, Las Cruces y Montemar. El 65,5% de la muestra estaba parasitada, recolectándose 2.410 metacercarias y 18 nemátodos. Algunas metacercarias correspondían a la familia Opecoelidae, mientras que otras a Microphallidae; los nematodos eran de la familia Cystidicolidae. La mayor prevalencia y abundancia de Microphallidae se registró en Petrolisthes tuberculosus (42,3%; 4,8 ± 11,08 parásitos/crustáceo y de Opecoelidae en P. violaceus (96,9%; 13,59 ± 17,50 parásitos/crustáceo, mientras que Cystidicolidae fue poco prevalente y abundante en ambas localidades. Las infecciones parasíticas fueron afectadas por la localidad de muestreo, especie y tamaño del hospedador. No se encontró asociación entre la abundancia de los hospedadores definitivos y las cargas parasitarias que presentaban los crustáceos. La nula relación entre las cargas parasitarias y la abundancia de hospedadores definitivos puede ocurrir si estos últimos tienen un amplio espectro trófico o viajan largas distancias, de este modo, la transmisión de los parásitos no sería afectada directamente por la abundancia de los hospedadores definitivos.

    Full Text Available Se comparan las infracomunidades de parásitos de la borrachilla Scartichthys viridis (Pisces: Blenniidae de tres muestras tomadas en un lapso de 17 meses, entre 1999 y 2001, desde pozas intermareales vecinas a Las Cruces (33°27' S, 71°37' O, Chile central. El objetivo es averiguar si la riqueza, diversidad, abundancia y composición de las infracomunidades de parásitos son persistentes o no en el tiempo ontogenético y cronológico. Se recolectaron 10 taxa parasitarios en cerca del 89 % de los 63 huéspedes examinados, de los cuales ocho eran metazoarios. La búsqueda de protozoos se realizó sólo en los últimos 2 años. El 75 % de los ocho taxa de metazoos ocurrieron en los tres años, uno no estuvo presente en un año, y otro fue encontrado solamente en un año. La mayoría de los huéspedes examinados albergaba protozoos parásitos. La prevalencia de los protozoos Cryptobia sp. fue alta para ambos años, y menor en Trichodina sp. La longitud total de los huéspedes era un predictor relevante de las variaciones en la riqueza, abundancia, diversidad y composición infracomunitaria en el conjunto de los tres años. En cambio, el año de muestreo no lo fue, en particular al comparar entre huéspedes de similar longitud total. Estos resultados son similares a los encontrados en infracomunidades de parásitos de otras especies de peces en Chile, en que hay baja variabilidad en las propiedades agregadas de las infracomunidades en el tiempo cronológico. Se discute acerca de la extensión relativa del tiempo ontogenético en contraste al tiempo cronológico al ser probablemente ambos de importancia en las características de las infracomunidades, y se propone que se explore la medida en la cual estos resultados constituyen un patrón.Parasite infracommunities of the blenny Scartichthys viridis (Pisces: Blenniidae are compared among three samples taken within a 17-month period during three consecutive years (1999-2001, from intertidal pools at

El grado de agrupamiento entre las zonas muestra las tres unidades biogeográficas definidas recientemente por Lancellotti & Vásquez. Este arreglo, que representa lo exhibido por los grupos más diversos, se ve alterado en los grupos menos representados donde las diferencias obedecen al patrón de afinidades mostradas por las zonas comprendidas dentro de la Región Templada Transicional.

    3.5 million people lived in Costa Rica as of mid-1997. There were 24 births and 4 deaths per 1000 population, respectively, contributing to the annual natural increase rate of 2.0%. Each woman in Costa Rica bears an average of 2.8 children during her reproductive lifespan and men and women were expected to live for 73 and 78 years, respectively. Costa Rica's low infant mortality rate and high literacy and life expectancy rates set it apart from the rest of Central America. Costa Rica is also the only country in the region which maintains no standing army. About 96% of the population is White or Mestizo, 3% is Black, and 1% is indigenous Indian. More than half of the country lives in San Jose and its metropolitan area, 6% of the country's total land area. Unemployment has run near 5% over the past 2 years, but much of the labor force is underemployed. Costa Rica's economy depends upon tourism and agricultural exports such as coffee, beef, and bananas. A large Intel factory opened in 1997. The government and Costa Rican environmentalists are planning a joint campaign to reconvert 80% of Costa Rica's pasture back to forest and tree crops. About 20% of the government's budget is spent upon education and the 93% literacy rate is the highest in the region. Government health services provide low-cost contraceptives to more than 75% of users and 75% of women use some form of family planning.

    Full Text Available A multi-center study was performed in Brazil, Chile, and Mexico to identify factors that may facilitate or hinder the introduction of emergency contraception (EC as well as perceptions concerning emergency contraceptive pills. Background information on the socio-cultural, political, and legal context and the characteristics of reproductive health services was collected. The opinions of potential users and providers were obtained through discussion groups, and those of authorities and policymakers through semi-structured interviews. Barriers to introduction included: perception of EC as an abortifacient, opposition by the Catholic Church, limited recognition of sexual and reproductive rights, limited sex education, and insensitivity to gender issues. Facilitating factors were: perception of EC as a method that would prevent abortion and pregnancy among adolescents and rape victims; interest in the method shown by potential users as well as by some providers and authorities. It appears possible to reduce barriers through support from segments of society committed to improving sexual and reproductive health and adequate training of health care providers.Foram identificados fatores que poderiam facilitar ou dificultar a introdução da anticoncepção de emergência (AE no Brasil, Chile e México.

    Full Text Available This article presents the results of a study on the acceptability of emergency contraception (EC in Brazil, Chile, and Mexico. Opinions of potential users and possible providers were obtained through discussion groups and those of authorities and policy-makers through semi-structured interviews. Most participants had a positive opinion of EC, based on the view that it can help reduce unplanned pregnancy, adolescent pregnancy, and unsafe abortion. Several interviewees felt that all women should be informed about EC, while others viewed it as a method for special situations such as rape and unprotected first sexual intercourse. Concern was expressed that its introduction might be associated with a decrease in condom use, increase in sexually transmitted diseases, and irresponsible or promiscuous sexual behavior among adolescents. The need for EC was clearly perceived by most participants, leading to the conclusion that health authorities have the responsibility of implementing programs for its introduction. Training of health care personnel should include the discussion of reproductive health problems that could be prevented by EC.Apresentam-se opiniões de potenciais usuárias e possíveis provedores de anticoncepção de emergência (AE no Brasil, Chile e México.

Catch rates of the royal red shrimp were standardized using Generalized Linear Models (GLM. Preliminary analysis on goodness-of-fit indicates that Gamma distribution was the most adequate to model catch rates as response variable on this specie.

The proposed model explained 18% of the total deviance, and temporal and spatial factors included (year, months, area and depth, were highly significant (p < 0.01. Since 2005, the catch rate shows an increment on their values as a consequence of a decrease in fishing effort. Catch rates also show monthly variations, with higher values during spring-summer 53 kg per trawl hour (kg ha-1 and lower in winter, with 40 kg ha-1. At spatial scale, the standardized catch rates show higher values for those hauls carried out over 500 m of depth and between 33º53’S-34º41’S. The current analysis produces a standardized catch rate time series for the royal red shrimp fishery. This time series can be used as an abundance index to calibrate

    Costa Rica's demographic and economic characteristics are highlighted. Costa Rica's demographic situation is unique in certain respects. Between the late 1950s and the late 1970s, the total fertility rate declined from about 7 to 4 and then stabilized instead of continuing to decline to 2 as expected. This is especially surprising since the level of contraceptive use is similar to that of most European countries. Approximately 2/3 of all couples practice contraception. It is possible that the rate will slowly decline to the expected level, but a delayed decline will ultimately produce a much larger population than initially expected. The demographic situation in Costa Rica is being carefully monitored for insights which might be useful in predicting future fertility patterns in other developing countries. The government of Costa Rica recognizes that family planning is a necessary component of maternal and child health care; however, most family planning services are provided by private organizations. In 1982, population size was 2.6 million, the crude birth rate was 30.7, the crude death rate was 3.9, infant mortality was 19.3, and the rate of natural increase was 2.7%. The population is predominantly Spanish, and the indigenous population totals only 20,000. 48% of the population is urban. Costa Rica has a relatively stable deomocratic government. It relationshiops with other countries are generally peaceful, but tensions between Nicaragua and Costa Rica are increasing. The country's economic situation deteriorated in recent years due primarily to a decline in the price of coffee, the country's principle export commodity. The trade deficit increased markedly, unemployment increased, and income fell sharply. The economic slowdown is now showing signs of a reversal. In 1983 exports, consisting primarily of coffee, bananas, beef, sugar, cane and cacao, totalled US$871 million, and imports, consisting mainly of manufactured goods and equipment, chemicals, fuel, food

It synthesizes the knowledge about this important ecosystem and lists the currently available literature. The study focuses on the coast of Pará and Maranhão states, which are covered by a continuous belt of mangroves. The mangrove flora comprises six mangrove tree species and several associated species. Mangrove tree height and stem diameter vary as a function of abiotic local stand parameters. Seasonal variation in rainfall and salinity affect the species' phenology and litter fall. Local population use products derived from mangrove plants for different purposes (e.g. fuel; medicinal; rural construction. The increase in the coastal population has given rise to conflicts, which impact on mangrove forest.O presente estudo apresenta uma compilação da literatura sobre a vegetação dos manguezais da costa norte do Brasil, apresentando uma síntese do conhecimento e listando a literatura disponível.

Usou-se 13 anos de dados ininterruptos de precipitação estimados através do algoritmo 3B42_V6 do projeto TRMM. Os ciclos foram analisados por quadrimestres. Para obter informações sobre amplitude, fase e fração de variância de cada ciclo, utilizou-se a análise harmônica do ciclo composto no período de 24 horas para cada quadrimestre. Regiões mais próximas da costa apresentaram ciclos modulados por mecanismos oceânicos e, portanto, tendem a apresentar o máximo de precipitação no início da manhã e a noite. Regiões mais afastadas da costa apresentaram máximos às 2100 UTC (17:00 HL em função dos mecanismos de convecção local. A região Nordeste do Pará apresentou as maiores amplitudes de precipitação. Durante o quadrimestre de janeiro a abril observou-se as maiores taxas de precipitação. Não há variações sazonais significativas na fase dos ciclos. Os dois harmônicos correspondem a cerca de 80% do total da variância diária dos dados.

    Full Text Available Por casi un siglo, varios autores han analizado los patrones de distribución de la fauna y flora marina del Pacífico de Sudamérica y de la costa de Chile en particular, con el propósito de establecer el número de las unidades biogeográficas presentes. Si bien los patrones generales actuales son relativamente bien conocidos, la mayoría de los estudios se ha enfocado en las discontinuidades distribucionales y en propuestas de clasificación más que en los factores y procesos dinámicos que han formado las unidades espaciales identificadas. Aun en el caso de las clasificaciones, las conclusiones publicadas se basan principalmente en el análisis de uno o pocos grupos seleccionados, y presentan diferencias importantes en los criterios de selección de los grupos, el número de especies involucrado y la metodología usada. Por otra parte, las discrepancias entre estudios específicos tienden a obscurecer un fenómeno relevante y de mayor escala como es la dinámica de las biotas, uno de los aspectos biogeográficos menos conocidos en Chile.

  1. Chile exploits LNG

    Energy Technology Data Exchange (ETDEWEB)

    1980-03-01

    Simultaneously with its exploitation of offshore hydrocarbon reservoirs Chile is developing the production and selling of LNG. Chile produces a large quantity of associated gas from its reservoirs at Megallanes and processes it at the Manantiales, Cullen and Posesion plants recovering propane, butane and natural gas liguids. The stripped gas is reinjected for pressure maintenance operations. With the completion of the LNG program full use of the gas will be achieved. It will totally meet the needs of combustible liquids for the central and northern parts of the country, a volume of 2200 million cu m/yr. For its treatment natural gas is sent through gas pipelines to the LNG plant at Cabo Negro. By means of a cooling process, the gas is cooled to -160 C where it becomes a liquid and its volume is reduced by a factor of 600. It is then stored in tanks at atmospheric pressure.

    The author describes a joint program to use renewables for rural electrification projects in Chile. The initial focus was in a limited part of the country, involving wind mapping, pilot project planning, training, and development of methodologies for comparative evaluations of resources. To this point three wind hybrid systems have been installed in one region, as a part of the regional private utility, and three additional projects are being designed. Additional resource assessment and training is ongoing. The author points out the difficulties in working with utilities, the importance of signed documentation, and the need to look at these programs as long term because of the time involved in introducing such new technologies.

Así mismo, utilizando modelos de regresión binomial se determinaron los riesgos relativos de mortalidad de los inmigrantes nicaragüenses versus personas nativas de Costa Rica con ajustes por edad, urbanización, desempleo, pobreza, educación y segregación residencial. Los hombres y mujeres nacidos en Nicaragua tuvieron un riesgo reducido de mortalidad de 32% y 34% respectivamente con relación a sus contrapartes nacidas en Costa Rica. Se notó que los riesgos de mortalidad por enfermedades infecciosas, cáncer, enfermedades crónicas pulmonares, enfermedades cardiovasculares, y enfermedades crónicas del hígado eran significativamente reducidos entre los inmigrantes nacidos en Nicaragua. El exceso significativo de mortalidad por homicidios se encontró entre los hombres nacidos en Nicaragua (RT = 1,35, 95% IC: 1,19; 1,53 y en mujeres (RT = 1,41, 95% IC: 1,02; 1,95.

    2012-12-01

    Recent measurements of Hg in air in the central valley of Costa Rica produced some remarkably high values (up to 700 ng Hg/m3;Castillo et al., 2011), raising concerns for public health. We made a broad assessment of Hg as an environmental contaminant in Costa Rica, and sampled and analyzed lake and wetland sediment and soils to derive atmospheric Hg deposition rates. We also measured Hg(0) in air in three locations, and sampled local fish that were analyzed for Hg. We set up a sampling program of Hg in hair of Costa Ricans, sampling hair from a broad crossection of the population, in combination with dietary and personal information. The lake sediments had Hg concentrations between 34 and 316 ppb Hg, with several lakes at common natural background concentrations (20-100 ppb Hg). Some lakes showed a Hg contamination component with concentrations well above simple background values. These sediments also were very rich in organic matter, and the high Hg concentrations may be a result of Hg focusing from the watersheds into the lake depositional environments. Deduced atmospheric deposition rates of Hg range from 0.16-0.25 ng Hg/cm2 per year, which is at the low end of the global range of measured wet atmospheric deposition rates. The observed Hg concentrations in sediment and soils thus can be characterized as natural background to mildly contaminated, but nothing that would indicate Hg inventories as expected from the reported high Hg air burdens. Some of our Hg(0) in air measurements were done at the same locations as those done earlier and yielded values between 0.6-4.2 ng Hg/m3; these values are similar to the low range measurements of Castillo et al. (their night time values), but we found no evidence in 2011 for their high daytime values. The range of a few ng Hg/m3 in air is compatible with global Hg dispersion modeling. Fish tissue of Trout and Tilapia gave a range of 68-112 ppb Hg (wet weight base), well below the 300 ppb Hg EPA alert level. Overall, these

    ESO, the European Southern Observatory, in reply to questions raised by the international media, as well as an ongoing debate about the so-called "Paranal case" in Chilean newspapers, would like to make a number of related observations concerning its status and continued operation in that country [1]. THE ESO OBSERVATORY SITES IN CHILE The European Southern Observatory, an international organisation established and supported by eight European countries, has been operating more than 30 years in the Republic of Chile. Here ESO maintains one of the world's prime astronomical observatories on the La Silla mountain in the southern part of the Atacama desert. This location is in the Fourth Chilean Region, some 600 km north of Santiago de Chile. In order to protect the La Silla site against dust and light pollution from possible future mining industries, roads and settlements, ESO early acquired the territory around this site. It totals about 825 sq. km and has effectively contributed to the preservation of its continued, excellent "astronomical" quality. Each year, more than 500 astronomers from European countries, Chile and elsewhere profit from this when they come to La Silla to observe with one or more of the 15 telescopes now located there. In 1987, the ESO Council [2] decided to embark upon one of the most prestigious and technologically advanced projects ever conceived in astronomy, the Very Large Telescope (VLT). It will consist of four interconnected 8.2-metre telescopes and will become the largest optical telescope in the world when it is ready. It is safe to predict that many exciting discoveries will be made with this instrument, and it will undoubtedly play a very important role in our exploration of the distant universe and its many mysteries during the coming decades. THE VLT AND PARANAL In order to find the best site for the VLT, ESO performed a thorough investigation of many possible mountain tops, both near La Silla and in Northern Chile. They showed

    One of the biggest earthquakes recorded in human history has recently devastated a large part of the Chilean territory and, followed by a Tsunami, destroyed cities, seaports, fishermen's coves, bridges, and countryside houses. This cataclysm affected a large proportion of our population, leaving homeless families, no working tools for work places, hospitals, schools, public buildings, museums. However, the loss of human Uves was small compared to similar disasters. It destroyed part of the national heritage as well as damaged people's living conditions. A national movement started immediately to help and recover, and international resources, both human and technological were also set in motion. As after previous earthquakes in Chile, young M.D.'s and medical students were organized in voluntary groups backed by institutions or by their own organizations and went from large cities as Santiago and others to provide medical and psychological care to those in most need. Young members and students of other health professions (nurses, physical therapists, etc.) were included in these groups or worked in their own ones. National and international experience indicates that the forthcoming months require special care of psychological reactions and sequel (posttraumatic stress symptoms) and health consequences after water pollution, restrictions in housing and deteriorated sanitary conditions. Nevertheless, our country will stand up once more.

    Servicio Paz y Justicia (SERPAJ) is a nongovernmental organization (NGO) established in Chile in 1977. It supports fundamental human dignity and rights by fighting discrimination and exclusion based upon individual differences. SERPAJ promotes training, organization, and the political participation of community members as part of the democratic process, working mainly with the at risk women, street children, and youth of Santiago's working-class neighborhoods. Groups participate in workshops and training courses on human rights and development, civic education, and methods of non-violent community action. In 1987, SERPAJ-Sur Oriente began to include the topic of sexuality and AIDS/STDs in courses training working-class women as community human rights agents. The NGO is therefore one of the first mainstream Chilean human rights organizations to incorporate HIV/AIDS issues. A basic facts brochure was developed, followed by a pilot education project developed in one neighborhood which was then systematically replicated in other neighborhoods. The comments of some people who have participated in SERPAJ workshops are presented.

    I de sidste årtier er Chile blevet et egentligt forbrugersamfund. Udbredelsen af forbrugskulturen og forbrugerismen er centrale fænomener i chilenernes dagligliv og har nået et omfang, som har konsekvenser for de borgere, der ikke kan deltage fuldt ud heri, noget som er typisk for et samfund med en...... ujævn økonomisk udvikling og med store sociale forskelle. Denne proces er ikke et produkt af en stille, fredelig og naturlig samfundsudvikling, således som magteliten og de toneangivende intellektuelle i Chile har fremstillet det.

  8. Wildfires in Chile: A review

    Science.gov (United States)

    Úbeda, Xavier; Sarricolea, Pablo

    2016-11-01

    This paper reviews the literature examining the wildfire phenomenon in Chile. Since ancient times, Chile's wildfires have shaped the country's landscape, but today, as in many other parts of the world, the fire regime - pattern, frequency and intensity - has grown at an alarming rate. In 2014, > 8000 fires were responsible for burning c. 130,000 ha, making it the worst year in Chile's recent history. The reasons for this increase appear to be the increment in the area planted with flammable species; the rejection of these landscape modifications on the part of local communities that target these plantations in arson attacks; and, the adoption of intensive forest management practices resulting in the accumulation of a high fuel load. These trends have left many native species in a precarious situation and forest plantation companies under considerable financial pressure. An additional problem is posed by fires at the wildland urban interface (WUI), threatening those inhabitants that live in Chile's most heavily populated cities. The prevalence of natural fires in Chile; the relationship between certain plant species and fire in terms of seed germination strategies and plant adaptation; the relationship between fire and invasive species; and, the need for fire prevention systems and territorial plans that include fire risk assessments are some of the key aspects discussed in this article. Several of the questions raised will require further research, including just how fire-dependent the ecosystems in Chile are, how the forest at the WUI can be better managed to prevent human and material damage, and how best to address the social controversy that pits the Mapuche population against the timber companies.

  9. Chile Energy Policy Review 2009

    2009-10-22

    Since 1990, Chile has been the fastest growing economy in Latin America thanks to sound economic management and integration into the global economy. Chile can also be proud of its energy policy achievements. The pioneering privatisation and liberalisation of its electricity sector in the 1980s was the foundation for a competitive energy sector, which has sustained the rapid growth of the Chilean economy over the past two decades. Nonetheless, Chile faces the continuing challenge of finding additional energy supplies to fuel economic growth. Chile has limited fossil energy resources and depends on imports to meet three-quarters of its energy needs. The country's electricity sector has faced three periods of significant stress over the past decade. The last episode took place in 2007/2008, when the loss of natural gas imports from Argentina was further exacerbated by a drought in the central system, where hydropower normally accounts for over half of electricity generation. Drawing on the experience of IEA member countries, the Review assesses Chile's major energy challenges and provides recommendations. Six main themes emerge: the successful liberalisation of the power sector in the 1980s; the essential role played by the state in ensuring energy security; the re-formulation of Chile's long-term energy policy; the proposed reorganisation of the institutional framework; greater independence for the system operators; and the need for a clear framework of regulation so that long-term investment decisions integrate social and environmental costs. This publication is essential reading for all who are interested in Chilean energy issues and in learning about the important role sound energy policy can play in developing a nation's economic and social welfare.

  12. Costa Rica saves infants' lives.

    1988-01-01

    Even though Costa Rica is underdeveloped economically, life expectancy has been increasing over the past decade and the illiteracy rate was only 7% in 1984. Infant mortality rates have plummeted since 1972 when the 1st national health plan and social security were instituted (pre-1972: 2.3% annual reduction in infant mortality; 1972-1980: 13% decline annually). Decreased risk in the 1st postnatal month of life was responsible for 34% of the decrease from 1972-1980. Control of disease, especially diarrhea and acute respiratory infection, accounted for most of the decline (51%). Immunizations accounted for 8%, prevention of infectious diseases for 10%, control of malnutrition for 5%, and control of death due to premature birth for 14% of the decrease in mortality. Infant death due to pregnancy and delivery complications and congenital defects did not decrease during this period. Socioeconomic conditions normally influence survival rates strongly, but socioeconomic change in Costa Rica during 1970-1980 accounted for only 1/3 of the reduction in infant mortality. These improvements included an increase in the number of educated women, economic growth and decline in fertility (a decrease from 7.6 to 3.4 births between 1960-1980). The majority of the reduction stemmed from utilization of family planning techniques and the reduction of health risk factors. By 1980, the health program initiated in the 1970's provided primary care to 60% of the population, immunized 95% of the children against poliomyelitis, diptheria, pertussis, tetanus, and measles, and by 1984, provided almost all households with a sewage system. Analyses of the impact of socioeconomic development, fertility regulation, hospital care, outpatient services, and primary health care on infant mortality showed that, before 1970, those areas with better economies had a lower mortality rate, and after 1970, the economy and mortality rate had become independent variables. Furthermore, the introduction of health

    Within the last decade natural gas gained considerable importance in Chile. The contribution of natural gas within the energy system will increase in the future by predicted 3.6% annually until the year 2015. Due to limited resources within its own country, the energy system of Chile depends on natural gas imports preferential from Argentina. Therefore, the aim of several stakeholders from policy and industry is to reduce the share of imported primary energy within the overall energy system. In order to reach this goal, the use of domestic resources and particularly the utilisation of biomass as one of the most important renewable sources of energy in Chile could play an important role. Against this background, the goal of this paper is the analysis of the technical potentials of biomethane as a substitute for natural gas. For the production of biomethane the anaerobic or bio-chemical (i.e. Biogas) as well as the thermo-chemical conversion pathways (i.e. Bio-SNG) are considered. The results of this analysis show that biomass converted to biomethane is a promising energy provision option for Chile and it contributes to the reduction of greenhouse gas emissions. (author)

    Full Text Available In late 2001 and early 2002, a dichotomous species of Codium appeared colonizing the low intertidal and shallow subtidal bottoms of Caldera Bay, northern Chile (27° 03’ S, 70° 51’ W. Due to the ecological and economic impact the species is having in Caldera Bay and its potential spread along the Chilean coastline, we studied the taxonomic identity of the species and examined its relationships with other dichotomous species of Codium reported for temperate Pacific South America. Morphological analyses suggest that the seaweeds from Caldera Bay belong to Codium fragile (Suringar Hariot. Not only is there strong agreement in internal and external morphological characters, but among all the species reported for Peru and Chile, this is the only one exhibiting utricles with rounded, apiculate tip terminating in a mucron. This species has a broad geographic distribution in temperate waters. In Chile it was known only from the coasts of Valdivia to the Straits of Magellan (39° 48’ S, 73° 26’ W to 53° 10’ S, 73° 49’ W. This is the first record of C. fragile in northern Chile, and this study discusses several alternative hypotheses for the presence of the species into this area. The morphological characteristics of the material collected in Caldera partially agree with diagnostic characters known for C. fragile subspecies tasmanicum and C. fragile subspecies tomentosoides. However, the rapid population spread of the species in northern Chile, and recent molecular analysis support the identification of this form as the invasive C. fragile subspecies tomentosoidesA fines de 2001 y principio de 2002, apareció en el norte de Chile una especie del género Codium, de morfología dicotómica, colonizando los niveles intermareales y submareales de la Bahía de Caldera (27° 03’ S, 70° 51’ O.

It has a prestressed concrete structure, and consists of a basement parking space for 105 vehicles, and nine storeys, providing altogether a floor surface of 12,000 ms2. The building rests on a ground area of 40 by 60 ms, and the main structure occupies 22 by 45 ms. This Bank is located in a district of narrow streets, but its main side overlooks a green open space, which will improve its visibility and appearance. The building structure is made up of a framework of prestressed beams and columns. The beams have been concreted at the site, and the joists, which are also prestressed, are factory made. This framework, at each floor level, constitutes the basis of a continuous slab, which renders the total structure exceedingly stiff. The main continuous girders span 11.22 ms spaces, and vary in cross section. The prestressing reinforcements consist of 6 Loeba type cables. This is an original design by Dr. Leonhardt, in which the cables are placed on three horizontal layers, of parabolic outline. Each cable is made up of 12 x 5.4 mm wires, with a breaking stress of 180 kg/mm2 The tensioning stress was 108 kg/mm2, and the total prestress load is 29,700 kgs.

    Bacteria antimicrobial resistance is an uncontrolled public health problem that progressively increases its magnitude and complexity. The Grupo Colaborativo de Resistencia, formed by a join of experts that represent 39 Chilean health institutions has been concerned with bacteria antimicrobial susceptibility in our country since 2008. In this document we present in vitro bacterial susceptibility accumulated during year 2012 belonging to 28 national health institutions that represent about 36% of hospital discharges in Chile. We consider of major importance to report periodically bacteria susceptibility so to keep the medical community updated to achieve target the empirical antimicrobial therapies and the control measures and prevention of the dissemination of multiresistant strains.

    Full Text Available El problema de la desigualdad en Chile ha sido abordado desde diferentes puntos de vista como la cuestión de la distribución de la riqueza o el acceso a los derechos sociales. Es este trabajo se observa el mismo problema pero desde la perspectiva recientemente esbozada por los movimientos sociales: la del racismo ambiental o la desigual distribución de los deshechos del desarrollo y el consumo. De esta manera se revisan sucintamente los principales conflictos que han surgido en el último tiempo a lo largo del país entre empresas públicas y privadas y comunidades locales y originarias. Así mismo se examinan las formas de organización que estas últimas han asumido y el estado actual de articulación entre ellas. De la revisión de la situación se concluye que estamos ante el surgimiento de un actor de nuevo tipo, que surge de las contradicciones del Chile neoliberal y que se diferencia del movimiento ecologista por vincular sus reivindicaciones a la defensa del territorio y al derecho a la autodeterminación de los pueblos.

    Carter, M

    Brazil is South America's largest country and home to nearly half of the continent's people. Despite solid economic growth, Brazil has one of the world's widest income disparities. In the early 1990s, nearly 40% of urban and 66% of rural Brazilians lived in poverty. The streets of Brazil's cities are home to a large population of street children. Although it is difficult to estimate, 10 million children and youths may be either homeless or making a meager living off of the streets. Street children may be linked to prostitution and drugs and be the targets or perpetrators of violence. Child labor is an issue in Brazil. Today an estimated 30% of rural children and 9% of urban children ages 10-13 work in the formal economy. In some rural areas, 60% of workers are ages 5-17. Child labor also contributes to Brazil's relatively low educational attainment levels. UNICEF estimates that around 1990 only 1/3 of all Brazilian children continued on to secondary school, compared to 74% and 47%, respectively, for the Latin America and Caribbean regions. Immunization rates among Brazil's children are rising but still lag slightly behind regional averages. The mortality rate for children under age 5 decreased dramatically from 181 deaths for every 1000 live births in 1960 to 61/1000 in 1994. During the same time period, the average number of children born to a woman during her lifetime dropped from 6.2 to 2.8. This fertility decline is related in part to increased access to and acceptance of family planning. Contraceptive prevalence, including traditional and modern methods, is around 66%, with female sterilization and the pill being the most popular methods. Brazil's abortion rates are high, despite laws limiting access to abortion services. One estimate suggests that about 30% of all pregnancies are terminated through abortion each year.

    Chile is characterised economically and culturally by mining. The copper industry is highly important. In 2007 two thirds of export proceeds were generated solely by copper, copper concentrate and other minerals. With the increase in the price of raw materials since 2004 the state income rose considerably with the result that the national debt was offset. However, this increase was barely noticeable among the wider public. Further reasons for doubt with regards to the mining industry are that a new mining project generally not only creates jobs, but also changes local structures, competes with water utilisation and usually leaves contaminated sites. The responsible politicians and mining authorities are aware of these relationships and are drawing up corresponding laws and decrees. These include the Environmental Act, the bills for mine closures and the systematic redevelopment of old mining sites. At least voluntary commitments for current large-scale mining are in force until the bills are passed. (orig.)

    Full Text Available Se calculó la tasa bruta de homicidio doloso (intencional en la población total de Costa Rica y las tasas de las poblaciones de costarricenses y de nicaragüenses, residentes en el país. Para ello se empleó la casuística de personas imputadas por homicidio, disponible en el acervo del Poder Judicial, y las estimaciones y proyecciones poblacionales de Costa Rica del INEC y del CCP, ambas ajustadas a 15 a 49 años de edad. La tasa bruta de homicidio doloso de Costa Rica en el período del Estudio (1993-2005 ha experimentado un incremento sutil y sostenido hasta alcanzar una cifra preocupante en el 2005. Aún así, la tasa costarricense – en el Continente Americano - sólo es superada por las del Canadá, Argentina y Chile. Las tasas de homicidio de los costarricenses, por año, son en magnitud como la mitad, y a veces menos, de las tasas de los nicaragüenses que residen en Costa Rica. Una mayor proclividad hacia el homicidio doloso en los nicaragüenses parece estar relacionada con su pasado histórico, similar al de otras naciones del Istmo, exceptuando Panamá y Costa Rica. Aunque este Estudio no incursiona en la causalidad del homicidio doloso, es lógico plantear que su prevención y control solo puede darse cuando se corrijan o mejoren sus determinantes, a saber, pobreza, equidad, educación, desempleo, consumo de drogas y tenencia de armas.

    Energy Technology Data Exchange (ETDEWEB)

    Baring-Gould, E.I.

    1997-12-01

    This paper describes a village application in Chile. The objective was to demonstrate the technical, economic and institutional viability of renewable energy for rural electrification, as well as to allow local partners to gain experience with hybrid/renewable technology, resource assessment, system siting and operation. A micro-grid system is viewed as a small village system, up to 1200 kWh/day load with a 50 kW peak load. It can consist of components of wind, photovoltaic, batteries, and conventional generators. It is usually associated with a single generator source, and uses batteries to cover light day time loads. This paper looks at the experiences learned from this project with regard to all of the facets of planning and installing this project.

  7. 2010 Chile Earthquake Aftershock Response

    2010-05-01

    The Mw=8.8 earthquake off the coast of Chile on 27 February 2010 is the 5th largest megathrust earthquake ever to be recorded and provides an unprecedented opportunity to advance our understanding of megathrust earthquakes and associated phenomena. The 2010 Chile earthquake ruptured the Concepcion-Constitucion segment of the Nazca/South America plate boundary, south of the Central Chile region and triggered a tsunami along the coast. Following the 2010 earthquake, a very energetic aftershock sequence is being observed in an area that is 600 km along strike from Valparaiso to 150 km south of Concepcion. Within the first three weeks there were over 260 aftershocks with magnitude 5.0 or greater and 18 with magnitude 6.0 or greater (NEIC, USGS). The Concepcion-Constitucion segment lies immediately north of the rupture zone associated with the great magnitude 9.5 Chile earthquake, and south of the 1906 and the 1985 Valparaiso earthquakes. The last great subduction earthquake in the region dates back to the February 1835 event described by Darwin (1871). Since 1835, part of the region was affected in the north by the Talca earthquake in December 1928, interpreted as a shallow dipping thrust event, and by the Chillan earthquake (Mw 7.9, January 1939), a slab-pull intermediate depth earthquake. For the last 30 years, geodetic studies in this area were consistent with a fully coupled elastic loading of the subduction interface at depth; this led to identify the area as a mature seismic gap with potential for an earthquake of magnitude of the order 8.5 or several earthquakes of lesser magnitude. What was less expected was the partial rupturing of the 1985 segment toward north. Today, the 2010 earthquake raises some disturbing questions: Why and how the rupture terminated where it did at the northern end? How did the 2010 earthquake load the adjacent segment to the north and did the 1985 earthquake only partially ruptured the plate interface leaving loaded asperities since

    Full Text Available The overview of the issue of South American naval competition between the late nineteenth and early twentieth century' has been hindered by a bilateral perspective. Based on a perception of the hard power, naval competition is not interpreted as an episode restricted to the case of Chile-Argentina or Argentina-Brazil, but as a regional political determination induced by the belief that naval competition would increase the chances for success in the international system. This search for prestige ended in the 1920s due to cultural reasons, Wilsonianism, the path of collective security being discredited after World War I, and the global pro-disarmament climate.

También se realizan comparaciones de la diversidad de carábidos chilenos con respecto a otros países y el Neotrópico. Para Chile, se conocen 21 tribus, con 95 géneros y 365 especies, que representan el 38,8, 28,8 y 7,9 % de la fauna del Neotrópico, respectivamente. Chile posee un bajo número de tribus comparado con otros países, sin embargo, constituye un área importante por la presencia de seis tribus relictuales, principalmente pangeicas o gondwánicas. Chile posee 18 géneros endémicos (18,5 % de su fauna de Carabidae, 28 cuya distribución está restringida a Chile y Argentina y seis restringidos a Chile, Argentina y Uruguay. La cantidad de especies presentes en Chile es inferior a la que poseen otros países de América del Sur, pero la cantidad de especies endémicas es muy alta (204 y representa el 55,8 % de su fauna de carábidos. El alto grado de endemismo que posee Chile con respecto a otros países de América del Sur puede deberse a su condición de aislamiento, siendo las barreras más importantes la región desértica del norte y la cordillera de Los Andes. Este hecho también se vislumbra por la ausencia de importantes tribus neotropicales como Galeritini, Scaritini y Brachinini. También se incluyen en este trabajo claves para la identificación de todas las tribus y géneros presentes en Chile, como así también una breve descripción acerca de la diversidad y ambientes en los que se encuentra cada géneroThe family Carabidae is the fourth largest Coleoptera family in Chile.

    Full Text Available We present the results for the reproductive biology of Patagonian toothfish (Dissostichus eleginoides caught off southern Chile from January to March and June to November 2006. A total of 10,896 specimens were measured (55-220 cm total length, TL and sexed (7,049 males, 64.7%; and 3,847 females, 35.3%. Macroscopic observations showed that gonad maturation begins at 60 cm TL in both sexes, with an average maturation size of 81 cm TL in males and 89 cm TL in females. This species appears to have an ampie spawning period that occurs only off the far southern region of Chile. To date, no evidence indicates that this resource reproduces in any other areas of the Pacific Ocean off the coasts of South América, where no specimens were observed with mature gonads, percentages of atresia were high, and juvenile fish were not caught in trawl fishing operations targeting other commercial species.Se dan a conocer resultados sobre la biología reproductiva del bacalao de profundidad (Dissostichus eleginoides capturado en el extremo sur-austral de Chile, entre enero y marzo y de junio a noviembre de 2006. En dicho período se midió y determinó el sexo a 10.896 ejemplares, comprendidos entre 55 y 220 cm de longitud total (LT, de los cuales 7.049 correspondieron a machos (64,7% y 3.847 a hembras (35,3%.

Se sugiere que esta especie presenta un período amplio de desove y que este proceso se efectuaría únicamente en la región austral de Chile, destacándose que hasta ahora no se cuenta con evidencias que este recurso se reproduzca en otra zona del océano Pacífico frente a la costa de Sudamérica en atención a la ausencia de ejemplares maduros en las capturas, altos porcentajes de atresia y ausencia de peces

    Molecular, clinical and epidemiological studies have established beyond doubt that human papiloma viruses (HPV) cause cervical cancer. The virus is also associated with genital warts and other less common cancers in oropharynx, vulva, vagina and penis. Worldwide, VPH genotypes 16 and 18 are the most common high risk genotypes, detected in near 70% of women with cervical cancer. The discovery of a cause-effect relationship between several carcinogenic microorganisms and cancer open avenues for new diagnostic, treatment and prevention strategies. In this issue of Revista Médica de Chile, two papers on HPV are presented. Guzman and colleagues demonstrate that HPV can be detected in 66% to 77% of healthy male adolescents bypolymerase chain reaction and that positivity depends on the site of the penis that is sampled. These results support the role of male to female transmission of high risk HPVs in Chile and should lead to even more active educational campaigns. The second paper provides recommendations for HPV vaccine use in Chile, generated by the Immunization Advisory Committee of the Chilean Infectious Disease Society. To issue these recommendations, the Committee analyzes the epidemiological information available on HPV infection and cervical cancer in Chile, vaccine safety and effectiveness data, and describes cost-effectiveness studies. Taking into account that universal vaccination is controversial, the Committee favors vaccine use in Chile and it's incorporation into a national program. However, there is an indication that the country requires the implementation of an integrated surveillance approach including cross matching of data obtained from HPV genotype surveillance, monitoring of vaccination coverage, and surveillance of cervical cancer. The final decision of universal vaccine use in Chile should be based on a through analysis of information.ev Mid Chile

  18. Oswaldo Costa, Antropofagia, y la crítica caníbal de la modernidad colonial

    Jáuregui, Carlos A.

    2015-12-01

    Full Text Available Oswaldo Costa was a key member of the Brazilian modernist Antropofagia (Anthropophagy movement of the late 1920s, yet he has been largely forgotten by critics and marginalized from national cultural history. Costa articulated —as no other member of the movement did, including his famous leader Oswald de Andrade— an Antropofagia intellectually engaged in what we call a cannibal critique of colonial modernity and Occidentalism. Costa’s Antropofagia cannibalized the historical archive, reading against the grain of a triumphant Western imperial history. Throughout his contributions to the Revista de Antropofagia, he questioned Brazil’s cultural allegiance to Europe, pointed out the existence of asynchronous temporalities within Brazil, and defied Eurocentric notions of civilization and progress that ideologically structure Brazilian nationalism in the ninetieth and twentieth centuries. He also enacted an anthropophagous re-reading of Brazilian historiography against its celebration of colonialism and proposed the necessity of a cultural decolonization. This article analyzes Costa’s principal contributions to Antropofagia and rescues his hitherto overlooked countercolonial thought from the oblivion of collective forgetting. Moreover, it examines Costa’s significant view of Brazilian modernity as a perfidious armistice with other barbarous temporalities, and of the Westernization of Brazil as a deceptive appearance that hides ever-present colonial antagonisms.Oswaldo Costa fue un miembro fundamental del movimiento modernista Antropofagia de finales de la década de 1920. Pese al olvido crítico de su obra y a su exclusión de la historia cultural brasileña, Costa articuló —como acaso ningún otro miembro del movimiento, incluyendo a su famoso líder Oswald de Andrade— una Antropofagia-otra, intelectualmente trabada en lo que denominamos una crítica caníbal de la modernidad colonial y del Occidentalismo.

Changing rooms for bathers, and a night club, in the basement. Restaurant and bar on the ground floor. Twelve living apartments on the six standard floor levels; two apartments per storey. Porter's house in the attic. As the foundations are in the sand, and the building is exposed to strong coastal winds, the structural design has, as interesting features, the foundation ribbed slab and the transversal portal frames, which are W shaped on the ground level. This arrangement makes the edifice look lighter and it acquires a more dynamic plasticity.En la Costa del Sol de Almería y a muy pocos metros de la orilla del mar, se ha construido este edificio de apartamentos.

    This article summarizes studies designed to evaluate the role of Helicobacter pylori infection in Chile, described in 21 reports from nine centers in various Chilean regions published between 1985 and 1995. According to their data, H. pylori infection is quite frequent among patients with a variety of gastric conditions, including adults (43%-92%) and children (6%-100%). Levels of specific IgG antibodies to H. pylori are also elevated among patients with duodenal ulcers (100%) and gastritis (86%) as well as asymptomatic adults (75%). Combination therapy with three (but not two) drugs has been proved effective, with clinical improvement, ulcer cure, and H. pylori eradication occurring in well-controlled studies. Available evidence suggests that antibiotic resistance is not a major problem in treatment. The H. pylori reinfection rate is low (4.2% per year), suggesting that combination therapy with three drugs constitutes a cost-effective alternative for treating colonized symptomatic patients. Concurrent preliminary studies revealed that antibodies to VacA but not CagA proteins correlate with disease severity in Chilean patients. It can be concluded that local research assists local administrators of health resources to implement adequate policies to prevent, control, and treat H. pylori-related pathologies.

    While some countries have unbundled distribution and retailing, skeptics argue that the physical attributes of electricity make retailers redundant. Instead, it is claimed that passive pass through of wholesale prices plus regulated charges for transmission and distribution suffice for customers to benefit from competitive generation markets. We review the Chilean experience with regulated retailing and pass through of wholesale prices. We argue that when energy wholesale prices are volatile and prices are stabilized, distortions emerge. Regulated retailers gain little by mitigating or correcting them. On the contrary, sometimes price distortions increase their profits. We estimate the cost of three distortions that neither regulated retailers nor the regulator have shown any interest in correcting. - Highlights: > We review Chile's experience with regulated electricity retailing. > Distortions emerge when energy wholesale prices are volatile and prices stabilized. > Regulated retailers gain little by mitigating or correcting distortions. > Sometimes price distortions increase retailers' profits. > We estimate the cost of three distortions, which retailers have not corrected.

    The main cause of human exposure to artificial radiation corresponds to medical applications, so it is essential to reduce the dose to patients, workers and consequently the entire population [1]. Although there is no dose limit for patients, is necessary to reduce it to a minimum possible while still getting all the necessary diagnostic information, taking economic and social factors into account [2]. Based on this proposal, agencies such as the International Atomic Energy Agency has been dedicated to providing guidelines levels, whose function is to serve as standards for the optimization of the medical exposure [3]. This research was created as a preliminary survey with the claim of eventually determine the guidance levels in Costa Rica for three different studies of general radiology: Lumbar Spine-AP, Chest - PA and Thoracic Spine - AP (for screens with speeds of 400 and 800), and cranio-caudal study in mammography, applied to Costa Rica's adult population, perform properly in the institutions of Caja Costarricense del Seguro Social (CCSS).

    The main goal of the RV SONNE cruise 161 SPOC (Subduction Processes Off Chile), Leg 1 and 4, was to investigate the effects of subducting aseismic ridges and frac- ture zones on the seismicity and structure of the Central Chilean Margin. Scientists from GEOMAR (Kiel), BGR (Hannover), FU Berlin (SFB 267), Universidad de Chile (Santiago) and Instituto Costaricense de Electricidad (Costa Rica) participated in data acquisition and analysis. The SPOC experiment consists of four consecutive legs off Valparaiso, Central Chile. During Leg 1 (October), an array of 23 ocean bottom hydrophons and seismome- ters (OBH/S) was deployed to register local earthquakes. In December (Leg 4), the network was recovered and a total of 125 OBH/S locations were occupied on five wide-angle profiles. They recorded more than 10.000 airgun shots, fired by an airgun array of 20 guns with a total volume of 50 liters. In addition, the wide-angle seis- mic lines were extended by land-based seismometers, operated by the Universidad de Chile, Santiago. Furthermore gravity, magnetics and high resolution bathymetry (SIMRADTM) and sediment echo-sound data (PARASOUNDTM) were recorded. On Legs 2 and 3, the BGR carried out a multi-channel reflection (MCS) seismic survey. Preliminary analysis of the data shows that a considerable number of local earthquakes has been recorded by the passive seismological network. Preliminary location of the hypocenters yield earthquake depths predominantly between 15 and 30 km. Many events registered by the local seismological network have been relocated~10 km west- wards of the previous land-based locations, which might indicate a bias in the existing catalogues. Wide-angle record sections of high quality were obtained, for all profiles shot. Mantle phases over offsets of more than 120 km were recorded by many stations. The pre- liminary velocity depth model derived for a profile striking E-W at 31a S across the subduction zone resolved the lateral transition on the

    Costa Rica has a diversity of volcanic crater lakes that can be classified into two groups: hot and cold lakes. The country contains at least 5% of the world's hot lakes. Costa Rica has 2 hot hyperacidic lakes, both of them on active volcanoes, the Rincón de la Vieja (38.0°C, pH = 0 - 1) and the Poás Laguna Caliente (36.1°C - 56°C, pH = 0.55 - 0.74), nowadays the Poás hot lake is the most active crater lake in the world, with more than 200 eruptions only on 2010. One of the most studied cold crater lakes is Irazú (13°C, pH = 3.5), that used to contain bubbling and clear areas of upwelling involving CO2 liberation and subaqueous fumaroles with temperatures up to 50°C, but since 2005 the lake presents an important descend until April 2010 when it disappeared. On February 9, 2003, Irazú's lake underwent a drastic change of color, from clear green to mustard with reddish loops, similar to the color of the waters of Lake Nyos after the gas burst of August 1986. Other studied cold lakes include Botos, Chato, and Tenorio, all at the summit of Quaternary volcanoes as well as Barva and Danta, located in recent pyroclastic cones.

    The Camamu and Reconcavo South Basins are located near the passive continental margin of the Bahia State, Brazil, and have high potential for hydrocarbon exploration. In these basins and surrounding basement, brittle and ductile structures were studied, which resulted in 3D stress field orientations by use of inversion methods. From this study, the following results are relevant: important control of the basement structural heritage on the basin formation and evolution; local strike-inversion of {sigma}{sub 1} and {sigma}{sub 3} orientations in transtensive settings; vertical {sigma}{sub 1} typical of extensional regime precedes sub horizontal {sigma}{sub 1} of transtensive one; in relation to basin's long axes, at least four main horizontal {sigma}{sub 1} orientations were obtained, involving parallel, orthogonal and two diagonal sets. This could be related to: parallel and orthogonal flexural stress due to the sedimentary load, local elastic rebound of fault blocks, stress channeling, density contrasts between oceanic and continental crusts and ridge pull of the adjacent oceanic plate; diagonals, due to a combination of first order regional and second order local stress fields. This suggest that the continental margin of the Bahia State evolves from a typical passive into a transtensive margin, with transpressive regime that have been observed in some places, in a classical evolution of the Wilson Cycle.

    Bearing in mind the current and pressing need for an update of the existing Chilean power supply system - which has been remarkably influenced by new requirements - the search for new energy supply sources has become a top priority. The wind resource, vis-a-vis its associated mature technology features and its apparent availability throughout Chile, comes forward as a feasible option likely to play a more important role in any future national energy generation matrix. With a view to understanding the local wind resource, this document surveys a sample set of wind profiles available in the northern Chile area, thus becoming the first public survey of this kind. It also tackles theoretical energy production and capacity factors. Those became the basis of the wind modelling we undertook for Chile's participation in COP15. This paper shows wind generation is a suitable option for curbing down Greenhouse Gas Emissions (GHG) in Chile. (author)

    Rickettsia felis is an emerging human pathogen associated primarily with the cat flea Ctenocephalides felis. In this study, we investigated the presence of Rickettsia felis in C. felis from Guatemala and Costa Rica. Ctenocephalides felis were collected directly from dogs and cats, and analyzed by polymerase chain reaction for Rickettsia-specific fragments of 17-kDa protein, OmpA, and citrate synthase genes. Rickettsia DNA was detected in 64% (55 of 86) and 58% (47 of 81) of flea pools in Guatemala and Costa Rica, respectively. Sequencing of gltA fragments identified R. felis genotype URRWXCal2 in samples from both countries, and genotype Rf2125 in Costa Rica. This is the first report of R. felis in Guatemala and of genotype Rf2125 in Costa Rica. The extensive presence of this pathogen in countries of Central America stresses the need for increased awareness and diagnosis. PMID:22665618

    2001-12-01

    The bathymetry of Coco's Island (UNESCO Natural and Cultural World Patrimony), located approximately 500 km from the Pacific coast of Costa Rica, is not well known. It has a high marine biodiversity and also represents a meeting site for many species traveling throughout the Pacific Ocean. The insular shelf is irregular in extension and also in bathymetric features. The northeast limit is defined by the 109.8-128.1 m contours (60-70 fathoms) while the 183 m contour (100 fathoms) practically defines the rest of the island, from which the depth gradient is steep. The maximum extension is to the northeast with a longitude of 13 km. In this context the present limits of the marine park (5 km), are insufficient to protect the whole insular shelf. Current regulation should be modified to prevent fishing activities less than 15 km from the Island.

    Full Text Available This presentation shows some of the consequences of the polio crisis in Costa Rica during the 1950’s, in order to preserve certain attitudes of Costa Ricans back then that are worth remembering: simplicity, solidarity and gratefulness. Hand in hand with highly service-oriented men and women, the country overcame the crisis and built one of the most iconic hospitals in Costa Rica: the National Children’s Hospital. It is worth rescuing the lessons learned and applying them to current times. This historical text was created based on the stories told by people who lived during the times of the crisis, on a 1956 notebook, on documents from the National Archive and the National Health and Social Security Library (BINASSS, for its name in Spanish, the Costa Rican Social Security System (CCSS, for its name in Spanish, Dr. Rodolfo Álvaro Murillo, and San Juan de Dios Hospital.  National and international newspapers were also reviewed. The consulted material confirms how the work of Costa Ricans, led by committed and service-oriented individuals, allowed for the construction of the National Children’s Hospital to take place -an institution that has served the Costa Rican people for fifty years. Costa Ricans also succeeded in eradicating polio long before several other countries around the world. The reactions of people in the 1950’s are lessons of solidarity and humanity that should not be forgotten; they should be remembered in order to value team work over individual work and make sure, no matter what our role in society is, to always stand by common well-being, as mid-century Costa Ricans did by overcoming their personal limitations and acting for the benefit of society.

    Full Text Available Abstract This article looks at the changes in party systems generally in modern democracies, and argues that many trends observed internationally - growing mistrust of parties, growing electoral de-alignment - are also observed in Chile. Hence any analysis of party change in Chile has to take into account what is happening in other countries with well-established party systems. The article argues that the comparison with the past tends to be limited to the exceptional 1964-1973 period and that a more extended analysis points to many continuities in the Chilean party system. Competing arguments over whether there is new party cleavage in Chile based on the opposition between support for authoritarianism or support for democracy are also examined*.Resumen Este artículo estudia los cambios generales en los sistemas de partidos en las democracias modernas y argumenta que muchas de las tendencias que se observan internacionalmente -como el aumento en la desconfianza en los partidos, o desalineaciones electorales cada vez mayores- también se observan en Chile. De esta forma, cualquier análisis de cambios en el sistema de partidos de Chile tiene que considerar lo que está sucediendo en otros países con sistemas de partidos bien establecidos. El artículo postula que la comparación del sistema de partidos chileno con el pasado reciente tiende a estar limitado al período excepcional 1964-1973 y que un análisis más extendido implicaría muchas más continuidades de las esperadas. También se cuestiona las nuevas discusiones sobre si existe o no una nueva fisura partidaria, basada en la oposición entre el apoyo y rechazo al sistema autoritario, o el apoyo a la democracia.

This paper describes the reproductive success of South American Terns on Cardos Island, Florianopolis, Brazil in the breeding seasons of 2003, 2005 and 2006. The colony was formed in mid-May in 2003 and early April in other years, with the total number of nests ranging from 1,852 in 2006 to 2,486 in 2005. Hatching success was estimated at 76.39% in 2006, 62.73% in 2003 and 41.1% in 2005, the lowest value that could be attributed to predation by hawks Caracara plancus, lizards Tupinambis merianae and black vulture Coragyps atratus. The chicks hatched in July in 2003, and in June 2005 and 2006, and fledging success was 50.94%, 35.96 and 53.47% respectively. Cardos Island has been constantly used as a breeding site by South American Terns, and therefore represents an important area for conservation of this species. This success could be attributed to low pressure of Kelp gulls (Larus dominicanus, the main predator of seabirds along the Brazilian coast.Sterna hirundinacea (Lesson, 1831 é uma ave migratória que nidifica na costa do Pacífico (do Peru ao Chile e ao longo do Atlântico Sul do Espírito Santo (Brasil até a Terra do Fogo (Argentina.

A comparative karyotype study was made between a population of A. presliana subsp. presliana and a population of A. presliana subsp. australis Ehr. Bayer. Both populations presented asymmetric karyotypes, with 2n = 2x = 16 chromosomes, but with different chromosome formulae: A. presliana subsp. presliana has a haploid formula with 4m + 1sm-sat + 1st-sat + 2t, i.e., four pairs ofmetacentric chromosomes, one submetacentric pair with satellite, one subtelocentric pair with satellite, and two telocentrics pairs. A. presliana subsp. australis has a formula with 2m + 1m-sat + 1sm + 4t chromosomes, i.e., two pairs of metacentric chromosomes, one metacentric pair with satellite, one submetacentric pair, and four telocentrics chromosomes. These results indicated that the karyotype of the subspecies is very different, and it would be possible to recognize A. presliana subsp. australis as a new species.Alstroemeria (Alstroemeriaceae es un género endémico de Sudamérica y presenta dos grandes centros de distribución: Chile y Brasil.

    2010-12-01

    The Federative Republic of Brazil has yesterday signed the formal accession agreement paving the way for it to become a Member State of the European Southern Observatory (ESO). Following government ratification Brazil will become the fifteenth Member State and the first from outside Europe. On 29 December 2010, at a ceremony in Brasilia, the Brazilian Minister of Science and Technology, Sergio Machado Rezende and the ESO Director General, Tim de Zeeuw signed the formal accession agreement aiming to make Brazil a Member State of the European Southern Observatory. Brazil will become the fifteen Member State and the first from outside Europe. Since the agreement means accession to an international convention, the agreement must now be submitted to the Brazilian Parliament for ratification [1]. The signing of the agreement followed the unanimous approval by the ESO Council during an extraordinary meeting on 21 December 2010. "Joining ESO will give new impetus to the development of science, technology and innovation in Brazil as part of the considerable efforts our government is making to keep the country advancing in these strategic areas," says Rezende. The European Southern Observatory has a long history of successful involvement with South America, ever since Chile was selected as the best site for its observatories in 1963. Until now, however, no non-European country has joined ESO as a Member State. "The membership of Brazil will give the vibrant Brazilian astronomical community full access to the most productive observatory in the world and open up opportunities for Brazilian high-tech industry to contribute to the European Extremely Large Telescope project. It will also bring new resources and skills to the organisation at the right time for them to make a major contribution to this exciting project," adds ESO Director General, Tim de Zeeuw.

    Abstract The taxonomic treatment of Begoniaceae for the state of Bahia, Brazil, led to the recognition of three new species of Begonia with narrow distributions, which are described and illustrated here: Begonia delicata Gregório & J.A.S. Costa, sp. nov. is a herb restricted to the region of the Recôncavo; Begonia elianeae Gregório & J.A.S. Costa, sp. nov. is a shrub endemic to the Atlantic forest of the southern part of the state; and Begonia paganuccii Gregório & J.A.S. Costa, sp. nov. is a subshrub known only from the type material, collected in the Piedmont of Paraguaçu. Notes on morphology, comparisons with morphologically similar species, etymology, geographic distribution, habitat and phenological data for each species are also presented. Furthermore, keys are provided as an aid to separating the new species from congeneric species that occur in their surroundings.

La vegetación predominante corresponde al bosque mixto siempre verde de la cordillera de la costa. Este es un bosque templado subpolar siempre verde ombrófilo rico en taloepífitas y en helechos que enraizan en el suelo. Las plantaciones de Pinus insigne, el desmantelamiento del bosque para terrenos de cultivo y los incendios forestales son los principales elementos responsables del retroceso del bosque valdiviano de Chile. Estamos estudiando las transformaciones espaciales y temporales que está provocando el fuego en estos bosques. Con el apoyo de fotos aéreas, análisis estadístico de datos de incendios, imágenes satelitarias y observaciones de campo; establecemos áreas piloto para estudiar fases de cambio en las áreas quemadas en los bosques de la montaña costera. Se determinan algunas reacciones de comunidades frente al fuego: por ejemplo los bosques de Fitzroya cupressoides no demuestran regeneración después de los incendios.

    20 years ago, Michael Schnitzler founded the NGO "Rainforest of the Austrians" to help save one of the most diverse rainforests in Central America, the Esquinas rainforest on the Pacific coast of SW Costa Rica, from being destroyed through logging. In this abstract we present an interdisciplinary upper Austrian school project aiming at building positive awareness in pupils towards rainforest conservation by fund-raising to help purchase endangered forest areas. The acquired rainforest was donated to the Costa Rican government and became part of the National Park "Piedras Blancas". In the following, we present a chronology of events and actions of the school project. We started our rainforest project by face-to-face encounters, letting involved persons speak directly to the pupils. Dr. Huber, coordinator of the tropical rainforest station La Gamba in Costa Rica (www.lagamba.at), together with Dr. Weissenhofer, presented an introductory slide show about the "Rainforest of the Austrians". With rainforest images and sounds in their mind the pupils wrote "trips of a lifetime" stories, thus creating idyllic images of rainforest habitats. Following up on that, we visited the exhibition "Heliconia and Hummingbirds" at the Biology Center in Linz. Reports about the slide show and the exhibition followed. Tropical sites were compared by producing climate graphs of La Gamba, Costa Rica, and Manaus in Brazil. The global distribution and the decrease of rainforests were also analyzed. In biology lessons the symbiosis between plants and animals of the rainforest were worked out by searching the Internet. Flyers with profiles of rainforest animals were produced. We also discussed the ecotourism project "RICANCIE" in Ecuador using fact sheets. "RICANCIE" is a Spanish acronym standing for "Indigenous Community Network of the Upper Napo for Intercultural Exchange and Ecotourism". It was founded in 1993 aiming to improve the quality of life for some 200 indigenous Kichwa families

    Full Text Available Desde 1979 se han reportado florecimientos de especies de microalgas nocivas (FAN en la costa Pacífica de Costa Rica, reconociéndose hasta el 2005 al menos 13 taxa de dinoflagelados. En años recientes estos fenómenos se han intensificado tanto espacial como temporalmente, produciéndose discoloraciones casi ininterrumpidas que se extienden por toda la costa produciendo mortalidad de peces y fetidez en el agua. Tales FAN masivos se iniciaron con Pyrodinium bahamense en el 2000, quien perduró por más de un año y en el cual se observaron morfotipos correspondientes a las dos variedades de la especie, coexistiendo junto a Gymnodinium catenatum y ocasionando serios casos de Intoxicación Paralizante por Consumo de Mariscos (IPM. Posteriormente, de septiembre del 2003 hasta junio del 2004, Cochlodinium cf. polykrikoides produjo discoloraciones en toda la costa Pacífica, seguidas por manchas extensas de Akasiwo sanguinea y Gymnodinium instriatum. El evento más reciente se observó en junio del 2005 cuando Alexandrium monilatum produjo extensas discoloraciones con cadenas formadas por más de 100 células. Los FAN de dinoflagelados ahora son comunes en las costas de Costa Rica, posiblemente como resultado de las condiciones ambientales actuales que favorecen la proliferación masiva de especies invasivas (agresivas, las cuales incluso pueden afectar otros sitios del Pacífico americano como es el caso de P. bahamense var. compressum que puede desplazarse hasta México, a lo largo de la costa del Pacífico centroamericano a través de la Corriente Costera de Costa Rica y la Corriente Occidental Mexicana.Since 1979 has been reported harmful microalgae blooms (HAB on the Pacific coast of Costa Rica, it was identified until 2005 at least 13 taxa of dinoflagellates.

Una buena parte de la atención se pone en el ritmo de la fecundidad en las etapas umbral, temprana y tardía de la disminución de la fecundidad que este país experimentó durante los años sesenta y principios de los setenta. Los resultados muestran bastante similitud en el tempo de la reproducción en los diferentes niveles paridez y áreas geográficas. Sin embargo, un análisis de las variables del entorno que afectan espaciamiento de los nacimientos muestra diferencias entre las zonas urbanas y rurales. Por último, se postula que el reciente estancamiento en las tasas de período puede ser una consecuencia de los cambios en el tempo de construcción de la familia, con mujeres de baja paridez que postergan los nacimientos, lo que contrarresta las tendencias de descenso que generan las mujeres de mayor paridez quienes aún pueden estar restringiendo su reproducción.ABSTRACTThis paper uses data from the Latin American Comparative Fertility Surveys as well as from the World Fertility Survey to study trends and differentials in birthspacing among ever married women in Costa Rica during the period 1945-1974.

    The thermoluminescence properties of the inorganic dust extracted from the Chile Guajillo (paprika) Mexicano, were studied in order to verify the possibility of using the TL technique to discriminate between irradiated and non irradiated peppers. The inorganic dust was found to consist of quartz 60%, albite (NaAlSi{sub 3}O{sub 8}) 30%, and ortose (KAlSi{sub 3}O{sub 8}) 10%. Its thermoluminescence dose response covers the wide dose range of 1Gy-10kGy, which was attributed mainly to feldspars. Its high sensitivity and its stability over 10 irradiation-readout cycles allow the application of a single grain-single aliquot regeneration dosimetry in Chile Guajillo (paprika). Evaluations based on trapping parameters show that thermal fading at room temperature for glow-peaks above 180 deg.. C, is not a problem in the dosimetry of paprika.

    Chile's tuberculosis morbidity notification statistics suggest that there has been a 3% average annual decrease in tuberculosis cases in the last 5 years (1978-82). In addition, over the period 1974-83, there was a 50% decline in the number of deaths from tuberculosis. In 1982, there were 6941 recorded cases of tuberculosis in Chile, only 6.5% of which involved children under 15 years of age; in that same year, there were 984 deaths from tuberculosis, 14.4% of which occurred in children. The majority of cases reported (78%) involve pulmonary tuberculosis. Over 90% of children under 15 years of age are covered by Bacille Calmette-Guerin (BCG) vaccination. This was achieved by immunizing 91% of all newborns, 83% of children in their first year of school, and 98% of those in their final year. Laboratories capable of case-finding now cover 95% of Chile's total area. Since 1975, an average of 47 bacilloscopies have been performed per 1000 consultations. Abandonment of treatment has been reduced to 12% and fewer than 20% of cases require hospitalization. Finally, the introduction of shortened rifampicin treatment has reduced the case-fatality rate from 6% to 3%.

    May-Collado, Laura J; Wartzok, Douglas

    2009-02-01

    Knowledge of the whistle structure in Guyana dolphins comes mostly from Brazilian populations where recordings have been made using limited bandwidth systems (18 and 24 kHz). In Brazil, Guyana dolphin whistle frequency span is 1.34-23.89 kHz, but authors have suggested that limits of their recording system may underestimate frequency span. Whistles of Guyana dolphins from Costa Rica were studied using a broadband recording system. How bandwidth limitations affect the understanding of whistle structure and species classification between sympatric dolphin species was evaluated. In addition, whistles were compared to Brazilian populations. Guyana dolphin whistle frequency span was 1.38 up to 48.40 kHz, greater than previously reported. Bandwidth limitations explained 89% of the whistle variation between studies, and increase in bandwidth improved the whistle classification of Guyana dolphins. Whistle duration and minimum frequency were the most important variables in dolphin species classification. Finally, after accounting for differences in recording systems, Costa Rican Guyana dolphins whistled with significantly higher frequency than Brazilian populations, providing evidence for a postulated increase in frequency from south to north. The study concludes that equipment with an upper frequency limit of at least 50 kHz (150 kHz for harmonics) is required to capture the entire whistle repertoire of the Guyana dolphin.

    Full Text Available Lutzomyia evandroi Costa Lima and Antunes, 1936 is found in Rio Grande do Norte, northeastern Brazil, in areas of visceral and mucocutaneous leishmaniasis and follows the same geographic distribution of L. longipalpis. The biological cycle, oviposition, morphological and behavioral characteristics of the species were studied under experimental conditions. The average number of eggs per wild caught female varied from 21 to 50 eggs along the year, with a peak occurring between January and March and another in August, with oviposition lasting for 4 to 12 days.

Para ampliar los reportes oficiales de la comercialización de alimentos para perros se creó una base de datos que incluyó cantidad, costo, empaque y formulación durante el período 1998 a agosto del 2000. De 1995 a 1998 y de 1996 a 1999 la producción nacional incrementó un 90,4% y la importación un 42,56% respectivamente, ocupando los alimentos nacionales un 72% del tonelaje y un 70% del valor en dólares americanos. No fue posible determinar cuál es el empaque más comercializado, pero si que los alimentos extrusados son los que ocupan el primer lugar y que los alimentos recomendados para cachorros y adultos son los que más se comercializan. La ausencia de datos en las declaraciones sugiere la necesidad de incrementar el control en las mismas en caso de requerirse un estudio de mercado, ya que contrariamente a esta situación el mayor número de garantías inscritas corresponden separadamente para las fases de cachorros y adultos. Merece también atención que las garantías indican mayores porcentajes de proteína cruda que los recomendados por la AAFCO y que al menos 36 fórmulas son recomendadas para estados sanitarios específicos (p.e. para perros con problemas de alergias, cálculos renales, pérdidas de pelo, etc. sin que oficialmente se encuentre registrada ninguna fórmula medicada

    The junctions of the Amazon and the Rio Negro Rivers at Manaus, Brazil. The Rio Negro flows 2300 km from Columbia, and is the dark current forming the north side of the river. It gets its color from the high tannin content in the water. The Amazon is sediment laden, appearing brown in this simulated natural color image. Manaus is the capital of Amazonas state, and has a population in excess of one million. The ASTER image covers an area of 60 x 45 km. This image was acquired on July 16, 2000 by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER will image Earth for the next 6 years to map and monitor the changing surface of our planet.ASTER is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, California, is the U.S. Science team leader; Bjorn Eng of JPL is the project manager. The Terra mission is part of NASA's Earth Science Enterprise, a long-term research and technology program designed to examine Earth's land, oceans, atmosphere, ice and life as a total integrated system.The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping, and monitoring dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface

Sin embargo, estos resultados variaron cuando se analizan las poblaciones de ambos rangos de distribución separadamente. La similitud genética no coincide con la divergencia morfológica entre individuos de la costa e interior, indicando que algunas poblaciones del interior están más relacionadas genéticamente, con poblaciones costeras que con aquellas de su mismo rango geográfico.The genus Alstroemeria consists of 82, exclusively South American taxa that are distributed mainly in Chile and Brazil. The great economic relevance, that has acquired the Chilean Alstroemeria species, as ornamentáis, has aroused great interest in the morphological variability of their flowers and genetic variability in those species with potential economic valué. One of these species is Alstroemeria hookeri which has four subspecies, of which A. hookeri subsp. hookeri, is endemic to the Maule and Biobio Regions. Its geographic distribution consists of two ranges, separated by the Coastal Mountain. Thus, there are populations growing in the coastal range, between 5-20 m high, in the provinces of Arauco, Concepción, Nuble, and Cauquenes, and populations of the Central Valley, growing between 100-150 m in the Biobio and Nuble provinces. Preliminary evidence indicated phenotypic differences between coastal and Central Valley populations, principally in colour and shape of the tepals. For this reason, a comparative morphological study was carried out in the complete geographic distribution of this subspecies and a population genetics study was conducted also, especially to determine the levéis of population structure. Thirty three floral characters were analyzed through ordination methods. The morphological study shows a slight tendency to separate the populations into two groups, which coincide with the extremes of morphological variation and both

    Full Text Available A malaria survey was conducted in an area of high transmission (Costa Marques, Rondonia, Brazil to determine the prevalence of asymptomatic parasitemia and its clinical significance. Most of the people surveyed were immigrants who had lived in the endemic area 2 days, 4 had only gametocytes, 1 had taken inadequate anti-malarial treatment, 3 were under treatment and 2 moved. Six asymptomatic patients denied the use of anti-malarial drugs and they developed malaria 3-6 days after the initial parasitological diagnosis. The final patient remained asymptomatic during the 7 day observation period. He had a history of > 40 malaria attacks and denied the use of antimalarial treatment. With the exception of the latter all of the other asymptomatic patients, were either in the incubation period or had been treated It is concluded that asymptomatic malaria is rare in the Costa Marques area and that it is necessary to treat all individuals with plasmodial parasitemia.

The officers in charge of each of the seven public DICs or DISs in Costa Rica were interviewed, and inquiries were made regarding aspects of the structure and process of their centers. Results: In Costa Rica there are seven public drug information units, that is, four DICs and three DISs. One of the DICs is located in this university, and the remaining six centers and services are in located in hospitals. Five of the centers do not have the primary sources required by the PAHO. Fifteen out of the 36 tertiary sources recommended are not available in any of the centers. 100% of the information units carry out four main activities: answering inquiries from the hospital community, answering inquiries from users outside the hospital, implementing education programs for patients and risk groups, and rotation programs for student training. Conclusions: The activities developed by the DISs and the DICs in Costa Rica are similar to each other; they respond not only to the PAHO’s guidelines, but they also have similarities with the activities and operations of other DICs worldwide. Primary, secondary, and tertiary bibliographical support must be strengthened.

    Full Text Available El Parque Nacional Volcán Poás, ubicado en el valle central de Costa Rica, es el parque más importante y que recibe más visitantes en el país. Entre el 24 de Marzo y el 10 de Abril del 2006, hubo una serie de erupciones que, la administración del parque prohibiera primero y restringiera después el acceso del número de visitantes al PNVP por tres semanas. El estudio examina el impacto de tales restricciones en las comunidades de Poasito y Fraijanes, las comunidades ubicadas en la entrada del parque, las cuales dependen económicamente de los gastos de los turistas que visitan el parque para sobrevivir. El estudio examina además el impacto social, de la falta información durante este tiempo en la opinión de las comunidades y los negocios sobre la gestión del desastre por parte de la administración del parque. Se encontró que para mejorar los planes para el manejo de esta clase de desastres, el parque y la comunidad deben mejorar la comunicación entre ambos, y la participación y coordinación de actividades. Para disminuir los riesgos de desastres físicos y económicos, la comunidad tiene que organizarse para pedir y obtener más información sobre las crisis generada por futuras erupciones y diversificar el tipo de turismo de que depende. La administración del Parque Nacional Volcán Poás debería iniciar actividades que ayuden el mejoramiento de la capacidad de participar de las comunidades en las actividades que el parque realiza en épocas de crisis, también debería incluir las necesidades informativas de la comunidad y de los negocios en su plan de gestión de desastres.

    Collections of mammals were made during more than three years of biological investigations in Chile sponsored by the Corporación Nacional Forestal under the aegis of the Peace Corps (Smithsonian Environmental Program). Genera and species hitherto unreported for that country were taken and many useful data concerning distributional patterns of other (mostly little-known) species were gathered. These collections have also proved valuable in better understanding Chilean mammals from a taxonomic point of view and contribute knowledge of the species' natural history. Specimens are to be deposited in the (United States) National Museum of Natural History (USNM) or are to be retained by the Corporación Nacional Forestal, Avda, Bulnes 285, Depto. 401, Santiago. Numbers provided below are field numbers. A final division of specimens between the two institutions has not yet been made. A number of specimens reported here were not taken by Peace Corps personnel but have been obtained by the National Museum of Natural History from other sources. Specimens in the Field Museum of Natural History (FMNH) were used in making comparisons. Some of Fulk's (GWF) specimens are at Texas Tech University. Other are at the Servicio Agricola y Ganadero in Santiago (as are specimens of some introduced species taken by Schamberger). Reise's (DF) are at the Universidad de Chile-Concepción and in his personal collection.

    The Government of Chile has placed a high priority on health promotion. This is evident in the advances made through its National Plan for Health Promotion (Plan Nacional de Promoción de la Salud) and the Vida Chile National Council for Health Promotion (Consejo Nacional para la Promoción de la Salud Vida Chile). Chaired by the minister of health, Vida Chile is made up of 28 public and private institutions from around the country. Vida Chile has a network of local councils that have been established in the country's comunas (communes, or local-level divisions of the country's provinces) and that include government officials and representatives of local societal and community organizations and private businesses. This report details the methods used to evaluate the National Plan as well as provides a preliminary assessment of the technical and financial results for the 1998-2006 period. Coverage indicators (number of participants; number of accredited health-promoting schools, workplaces, and universities; and number of health promotion events) and the extent of strategy implementation were used to measure the success of the program. Health promotion activities grew markedly during this period. Among the notable accomplishments were the following four: (1) 98% of the communes now have their own community health promotion plan and intersectoral Vida Chile committee to implement the plan, (2) there has been an increase in societal and community groups involved in the health promotion strategies, (3) 34% of the primary and secondary schools have become accredited health-promoting schools, and (4) approximately 20% of the total population benefited directly from community-health-plan activities in 2006. The average per capita cost of the community health plans' activities in 2006 was US$ 6.60. The two most important factors that facilitated the operation of the local health promotion plans were participation by community and societal groups and having an adequate

La bacteria Burkholderia glumae está asociada al cultivo del arroz en el que provoca la enfermedad llamada añublo bacterial. Bajo condiciones ambientales favorables, la densidad bacteriana aumenta, lo que provoca que, bajo un sistema de regulación denominado quorum sensing, se expresen sus mecanismos de virulencia mediante la activación de genes responsables para la síntesis de la toxoflavina, que bloquea el flujo de nutrientes, para la biogénesis de flagelos y la respuesta quimiotáctica, y la producción de la enzima catalasa. Las plantas desarrollan la sintomatología que finalmente conlleva a un vaneamiento del grano provocando pérdidas económicas importantes. Se investigó la situación referente a la contaminación del grano de arroz causado por esta bacteria en Costa Rica durante los años 2009 y 2010, mediante un convenio entre la Corporación Nacional Arrocera y el Laboratorio de Fitopatología del Centro de Investigación en Protección de Cultivos de la Universidad de Costa Rica. Se usó la metodología de PCR de punto final recomendada por investigadores del Centro Internacional de Agricultura Tropical en Colombia y se reforzó la identificación, por medio de técnicas de microbiología convencional. Se obtuvieron resultados que indican la presencia de la bacteria en Costa Rica, la primera información sobre la prevalencia de un fitopatógeno bacteriano de gran importancia para el sector arrocero.

    Full Text Available Along the coast of central Chile, geographic trends of diversity have been inferred from literature compilations and museum collections based on species range limits for some taxonomic groups. However, spatially-intensive field-based assessments of macrobenthic species richness are largely missing. Over the course of a multiyear study (1998-2005, we characterized latitudinal patterns of rocky intertidal diversity at 18 sites along the coast of central Chile (29-36° S. At each site, the number of sessile and mobile macrobenthic species was quantified in 0.25 m² quadrats. Two estimators of local (alpha diversity were used: observed local species richness, calculated from the asymptote of a species-rarefaction curve, and the Chao2 index, which takes into account the effect of rare species on estimates of local richness. We identified a total of 71 species belonging to 66 genera for a total of 86 taxa. The most diverse groups were herbivorous mollusks (27 taxa and macroalgae (43 taxa. Diversity showed a complex spatial pattern with areas of high species richness interspersed with areas of low richness. In accordance with previous work, we found no trend in the number of herbivorous mollusks and an inverse and significant latitudinal gradient in the number of algal species. Our results highlight the need for taxonomically diverse assessments of biodiversity of the dominant taxa that conform intertidal communities.A lo largo de la costa de Chile central, los patrones geográficos de diversidad han sido inferidos a partir de revisiones literarias y colecciones de museos para algunos grupos taxonómicos. Sin embargo, aun no contamos con una evaluación integral, y en terreno, de la riqueza de especies macrobentónicas intermareales.

Las autoridades chilenas, conscientes de este extenso territorio marítimo, han desarrollado un sistema de alerta de tsunami como una responsabilidad estatal y han depositado su control a la oficina nacional de emergencia – ministerio del interior (ONEMI) y en el servicio hidrográfico y oceanográfico de la armada de Chile (SHOA). En este artículo hemos realizado experiencias con el objetivo de activar los sistemas de advertencias generando eventos telúricos ficticios y/o eventos telúricos históricos capaces de desatar eventos de tsunami. También se ha propuesto una hipótesis de trabajo que permita, a través de los procedimientos establecidos por ley de la República de Chile, monitorear los tiempos de respuestas de los organismos estatales. Nuestro trabajo de investigación entrega resultados que nos permiten afirmar que existen zonas para eventos hipotéticos que podrían generar tsunamis a los cuales el sistema de alerta no sería eficiente en reaccionar. Para llevar a cabo esta investigación hemos utilizado un software llamado SLAT, basado en ecuaciones simplificadas de propagación de una onda de tsunami que nos permite obtener resultados rápidos y además hemos sometido a prueba el sistema con datos oficiales en los cuales se ha demostrado que el sistema de alerta no fue capaz de reaccionar al evento Atico 8,4 M. ocurrido en Perú.The Chilean territory has an extensive coastline -about 80.000 km of coast including the territory of its islands – which is an important fact to consider in the event of the occurrence of a tsunami.

Los valores de incidencia y severidad fueron mayores para el tratamiento con 50% de abono. En este tratamiento se presentaron síntomas de marchitez. La ausencia de diferencias en las variables de peso fresco y seco entre los tratamientos inoculados y sin inocular, a los que se adicionó abono al 25%, sugiere que esta dosis podría compensar el daño causado por el patógeno. Se observó una menor concentración de nutrimentos en los tejidos de las plantas inoculadas lo que indica que el daño causado a la raíz pudo haber afectado la adquisición de nutrimentos.

    Full Text Available The distribution of Concholepas concholepas (Mollusca, Gastropoda, Muricidae is limited to the coasts of Chile and southern Peru. Almost all studies of this gastropod have been carried out in open coastal systems, rather than the fjords and channels of southern Chile, despite the fact that this area represents ca. 95 % of the total coastline in this country. Although there is a large volume of background literature on C. concholepas, almost nothing is published about early larval development under natural conditions, mostly because early veligers have rarely been found in nature. This study is the first attempt to determine the spatial and temporal abundance and size patterns of C. concholepas larvae in their natural environment throughout all of their developmental stages until they settle. Weekly plankton samples were obtained at the surface and at 8 m depth in four locations in southern Chile in combination with temperature and salinity records in each location. Settlement was quantified using artificial substrates in all locations. We have observed that C. concholepas larval development occurs throughout the entire year in Chilean inland seas, with early veliger larvae being released mostly from August to March, reaching the competent stage around June to August, and settling between July and August. Thus, larvae appear to have a long planktonic development that can last between 6 and 12 months. Differences in local hydrology could affect larval development of C. concholepas in this region. Further oceanographic and ecological investigation is necessary in order to answer the questions and hypotheses originated from this studyConcholepas concholepas (Mollusca, Gastropoda, Muricidae se distribuye entre las costas del sur de Perú y extremo sur de Chile. Prácticamente todos los estudios sobre este gastrópodo han sido realizados en costas expuestas, sin considerar los fiordos y canales del sur de Chile, a pesar de que estos representan

    Full Text Available Costa Rica is stuck in a transition phase between an efficiency-based economy and an innovation-based economy and is not promoting the necessary entrepreneurial conditions that would lead to the required transformation.  Meanwhile, other countries in the region are in a better position to encourage entrepreneurship. In this situation, it is important to ask which are the conditions regarding entrepreneurship in Costa Rica that could improve the transition to an innovation-based economy. To improve this situation, the country must develop an inter-institutional support program that attracts direct foreign investment and linkages between businesses, improve human capital, provide training, incubation and funding, and have better articulation of public policy.

    Isla del Coco lies at 5 degrees 32'N latitude, 87 degrees 04'W longitude and is the sole peak of the Cocos Ridge exposed above sea level. This isolated island formed approximately 2 million years ago. It rises 575 m above the surface of the sea and covers 46 km2 (Castillo et aI., 1988). Five hundred km to the NNE is Costa Rica; 630 km SSW are the Galapagos Islands; 650 km to the E is Isla Malpelo, Colombia; and approximately 8,000 km W lie the Line Islands. Costa Rica claimed Isla del Coco in 1832 and declared it a National Park in 1978. The area of the park was increased to include the adjacent waters 5 km offshore in 1984 and 25 km offshore in 1991.

Por esta razón, en este trabajo se revisa la información existente y los argumentos que sustentan ambas posiciones. Se empleó una muestra de 300 individuos de los períodos Arcaico Tardío, Formativo, Medio y Tardío de sitios de la Costa y Valle de Azapa.

    Full Text Available El objetivo de este trabajo fue determinar la presencia de Burkholderia glumae en arroz en Costa Rica. La bacteria Burkholderia glumae está asociada al cultivo del arroz en el que provoca la enfermedad llamada añublo bacterial. Bajo condiciones ambientales favorables, la densidad bacteriana aumenta, lo que provoca que, bajo un sistema de regulación denominado quorum sensing, se expresen sus mecanismos de virulencia mediante la activación de genes responsables para la síntesis de la toxoflavina, que bloquea el flujo de nutrientes, para la biogénesis de flagelos y la respuesta quimiotáctica, y la producción de la enzima catalasa. Las plantas desarrollan la sintomatología que finalmente conlleva a un vaneamiento del grano provocando pérdidas económicas importantes. Se investigó la situación referente a la contaminación del grano de arroz causado por esta bacteria en Costa Rica durante los años 2009 y 2010, mediante un convenio entre la Corporación Nacional Arrocera y el Laboratorio de Fitopatología del Centro de Investigación en Protección de Cultivos de la Universidad de Costa Rica. Se usó la metodología de PCR de punto final recomendada por investigadores del Centro Internacional de Agricultura Tropical en Colombia y se reforzó la identificación, por medio de técnicas de microbiología convencional. Se obtuvieron resultados que indican la presencia de la bacteria en Costa Rica, la primera información sobre la prevalencia de un fitopatógeno bacteriano de gran importancia para el sector arrocero.

  9. Social Networks and Political Parties in Chile

    Directory of Open Access Journals (Sweden)

    Adler Lomnitz, Larissa

    2002-09-01

    Full Text Available This paper describes the origin and evolution of two Chilean political parties (the Radical Party and the Christian Democrat Party through the analysis of the social networks that originated and composed them. The aim of this study is to propose a model of national political cultures on the basis of the structure of social networks related to power and of the symbol system, which legitimizes it. The structure of social networks, horizontal and vertical, are based on reciprocal or redistributive forms of exchange, on what is being exchanged and on the articulation between networks. In every society there are symmetrical and asymmetrical exchanges, which produce horizontal and vertical networks. These networks interact among themselves to form the social fabric. The dominance of some over others and how they combine, delineate the character of the political culture (authoritarian vs. egalitarian. Chile is a multiparty country within which there are cohorts of horizontal groups of friends, who informally exercise a central control over their members and create invisible boundaries setting them apart from others, in which leadership is under constrains. The result is both a strong presidential system based on an almost fanatic legitimacy, combined with factionalism and a strong parliamentary system.

  10. Macroeconomic fluctuations and bank behavior in Chile

    2008-03-01

    Full Text Available The purpose of this study is to analyze bank behavior in Chile over time, looking at how their balance sheets and performance move both in the short and long run, and how they react to macroeconomic shocks. The evolution of banking aggregates over an 18 year period (1989-2006, using quarterly data is examined. Techniques common in the real business cycle literature are applied to establish empirical patterns. Robustness tests using several filters are performed. The effects of macro shocks on banking variables are analyzed, both by means of an event study, and by estimating impulse responses with VARs. The results show that credit lags the cycle, demand deposits lead it, both being procyclical, while the capital adequacy ratio (CAR is countercyclical. In addition, a shock to interest rates reduces loans (total, commercial, consumption, and increases non performing loans (NPL and the capital adequacy ratio (CAR. A shock to GDP growth has a positive effect on loans, return over equity (ROE, and a negative impact on NPL and CAR.

    The purpose of the present study was to determine the protein quality and digestibility of shellfish commonly consumed in Chile, and to estimate its contribution to the protein needs of the Chilean population. The shellfish studied were chorito (Mytilus edulis chilensis), macha (Mesodesma donacium), loco (Concholepas concholepas), cholga (Aulacomya ater), erizo (Loxechinus albus) and almeja (no specific variety). The NPU method was used to determine protein quality. The percentage of protein adequacy for adult rations was calculated according to FAO/WHO 1973. The contribution of shellfish to the protein availability according to the family income of the Santiago population, was also calculated. Most of the shellfish presented NPU values of about 70; the lowest values were found for loco (54.9) and macha (63.3). The apparent and true digestibility gave an average of 83.6 and 90.4, respectively. The percentage of protein adequacy of habitual rations ranged between 27% (erizo) and 58% (loco). The availability of shellfish protein in relation to total protein increased from 0.4 to 2.5% when income increased. It is concluded therefore, that shellfish protein is, in general, of good quality. Nevertheless, it might be considered of poor influence insofar as fulfilling the protein needs of the population studied, whatever its socioeconomic level.

    This article analyses and compares the epidemiology of mental disorders and relevant public policies in Chile and Finland. In Chile, a specific mental health law is still lacking. While both countries highlight the role of primary care, Finland places more emphasis on participation and recovery of service users. Comprehensive mental health policies from Finland, such as a successful suicide prevention program, are presented. Both countries have similar prevalence of mental disorders, high alcohol consumption and high suicide rates. In Chile, the percentage of total disease burden due to psychiatric disorders is 13% and in Finland 14%. However, the resources to address these issues are very different. Finland spends 4.5% of its health budget on mental health, while in Chile the percentage is 2.2%. This results in differences in human resources and service provision. Finland has five times more psychiatric outpatient visits, four times more psychiatrists, triple antidepressant use and twice more clinical guidelines for different psychiatric conditions. In conclusion, both countries have similar challenges but differing realities. This may help to identify gaps and potential solutions for public health challenges in Chile. Finland’s experience demonstrates the importance of political will and long-term vision in the construction of mental health policies.

    1994-02-01

    The evolutionist ideas of Lamarck, Darwin and Haeckel entered the country through the arrival of their books. "On the origin of Species" arrived in Chile in 1869. The most outstanding immigrant european physicians that discussed these ideas were Rodulfo A Phillippi (1808-1904) and Juan José Brunner (1825-1899). Both discussed Darwin's ideas in their books and conferences as academics of the Faculty of Medicine of the University of Chile. The first Chilean physicians that read and discussed the validity of evolution theory were Adolfo Valderrama (1834-1902) and Pedro Candia Salgado. Both wrote articles about this matter in Revista Médica de Chile in 1872 and 1874. The professor of general biology, Juan Noé Crevani, italian physician and zoologist that arrived in Chile in 1912, was the first to teach directly the concepts of the evolution theory until his death in 1947. Professor Noé founded the great biological school of the twentieth century in Chile and his disciples introduced the concepts of Mendelian theory and neodarwinism in the decade of fifties. The theory of evolution was taught as a chapter of general biology in the Faculty of Medicine between 1913 and 1947, but its practical applications to medicine were introduced with the birth of medical genetics in the decade of fifties and the foundation of Chilean Genetics society in 1964, under the direction of professors Danko Brncic and Gustavo Hoecker, both awarded with the National Sciences Prize.

Con este artículo se pretende dar a conocer las necesidades curriculares identificadas en niñas y niños nicaragüenses migrantes que estudian en la escuela primaria rural Los Ángeles del Cantón Los Chiles de Costa Rica. Ellos y ellas, actualmente, se encuentran en una situación de exclusión, discriminación e indiferencia por parte de las instituciones locales. Existen obstáculos para el aprendizaje efectivo y el desarrollo de actitudes positivas, entre ellos la falta de participación responsable de la comunidad educativa, el procedimiento metodológico utilizado en el aula y la adecuación curricular del modelo pedagógico oficial costarricense; divorciados éstos, de las condiciones socioculturales de esta población educativa, de su familia y de la comunidad rural donde residen. Esta situación afecta la motivación de las niñas y niños, quienes no alcanzan las metas educativas: la mayoría de los que se matriculan dejan inconclusa la educación primaria, y los que la completan tienen dificultades académicas para ingresar a secundaria. Los sistemas educativos de Nicaragua y de Costa Rica deben plantear estrategias educativas conjuntas, que den respuesta a las necesidades educativas curriculares que presentan los niños nicaragüenses migrantes en las escuelas rurales costarricenses.  Abstract.

  1. Costa Rica's 'White legend': how racial narratives undermine its health care system.

    Science.gov (United States)

    Campo-Engelstein, Lisa; Meagher, Karen

    2011-08-01

    A dominant cultural narrative within Costa Rica describes Costa Ricans not only as different from their Central American neighbours, but it also exalts them as better: specifically, as more white, peaceful, egalitarian and democratic. This notion of Costa Rican exceptionalism played a key role in the creation of their health care system, which is based on the four core principles of equity, universality, solidarity and obligation. While the political justification and design of the current health care system does, in part, realize this ideal, we argue that the narrative of Costa Rican exceptionalism prevents the full actualization of these principles by marginalizing and excluding disadvantaged groups, especially indigenous and black citizens and the substantial Nicaraguan minority. We offer three suggestions to mitigate the self-undermining effects of the dominant national narrative: 1) encouragement and development of counternarratives; 2) support of an emerging field of Costa Rican bioethics; and 3) decoupling health and national successes.

    Biological dosimetry is a necessary support for national radiation protection programs and emergency response schemes. The Latin American Biological Dosimetry Network (LBDNet) was formally founded in 2007 for mutual assistance in case of radiation emergencies and for providing support to other Latin American countries that do not have bio dosimetry laboratories. In the frame of the IAEA Technical Cooperation Projects RLA/9/54 and RLA/9/61 the following activities have been performed: a) An international intercomparison exercise organized during 2007-2008 included six European countries and LBDNet laboratories. Relevant parameters related with dose assessment were evaluated through triage and conventional scoring criteria. A new approach for statistical data analysis was developed including assessment of inter-laboratory reproducibility and intra-laboratory repeatability. Overall, the laboratory performance was satisfactory for mutual cooperation purposes. b) In 2009, LBDNet and two European countries carried out a digital image intercomparison exercise involving dose assessment from metaphase images distributed electronically through internet. The main objectives were to evaluate scoring feasibility on metaphase images and time response. In addition a re-examination phase was considered in which the most controversial images were discussed jointly, this allowed for the development of a homogeneous scoring criteria within the network. c) A further exercise was performed during 2009 involving the shipment of biological samples for biological dosimetry assessment. The aim of this exercise was to test the timely and properly sending and receiving blood samples under national and international regulations. A total of 14 laboratories participated in this joint IAEA, PAHO and WHO. (Author)

    2009-06-01

    On 2 May 2008, a large eruption began unexpectedly at the inconspicuous Chaitén volcano in Chile's southern volcanic zone. Ash columns abruptly jetted from the volcano into the stratosphere, followed by lava dome effusion and continuous low-altitude ash plumes [Lara, 2009]. Apocalyptic photographs of eruption plumes suffused with lightning were circulated globally. Effects of the eruption were extensive. Floods and lahars inundated the town of Chaitén, and its 4625 residents were evacuated. Widespread ashfall and drifting ash clouds closed regional airports and cancelled hundreds of domestic flights in Argentina and Chile and numerous international flights [Guffanti et al., 2008]. Ash heavily affected the aquaculture industry in the nearby Gulf of Corcovado, curtailed ecotourism, and closed regional nature preserves. To better prepare for future eruptions, the Chilean government has boosted support for monitoring and hazard mitigation at Chaitén and at 42 other highly hazardous, active volcanoes in Chile.

    Full Text Available Despite success in reducing poverty over the last twenty years, inequality in Chile has remained virtually unchanged, making Chile one of the least equal countries in the world. High levels of inequality have been shown to hamper further reductions in poverty as well as economic growth and local inequality has been shown to affect such outcomes as violence and health. The study of inequality at the local level is thus crucial for understanding the economic well-being of a country. Local measures of inequality have been difficult to obtain, but recent theoretical advances have enabled the combination of survey and census data to obtain estimators of inequality that are robust at disaggregated geographic levels. In this paper, we employ this methodology to produce consistent estimators of inequality for every county in Chile. We find a great deal of variation in inequality, with countylevel Gini coefficients ranging from 0.41 to 0.63.

  15. Globalization, Inequality, and Transnational Activism: A Case Study on Chile

    Directory of Open Access Journals (Sweden)

    Moctezuma Garcia

    2013-09-01

    Full Text Available Globalization has transformed how states are governed through a neoliberal economic approach that reinforces an unregulated capitalist market. An emphasis on Chile is important because it was the first state in Latin America to apply neoliberalism and has been hailed as a prime example for other developing states to integrate similar strategies to strengthen the local economy. However, inequality continues to persist despite economic gains. A combination of historical struggles affecting victims of the Pinochet era and present struggles with poverty, have resulted in a constant conflict between the power elite and the rest of society. Social movements in Chile have played a pivotal role in raising international awareness and pressuring the local government to protect the rights of highly vulnerable populations. A focus on transnational activism provides an effective medium for local and international advocates to work together toward holding Chile accountable for addressing social disparities.

    2001-06-01

    Cetacean strandings in Costa Rica are reported for a period of 33 years, with a total of 35 strandings, 13 species and 247 individuals involved. The vast majority of documented strandings occurred on the Pacific coast and correspond to single individuals (32 and 28 strandings respectively). The highest stranding number was in the period from 1990 to 1999 (n = 24). Physeter catodon (cachalot or sperm whale) is the species with the highest frequency of strandings (n = 8) and the family Delphinidae has the majority of species (n = 8) and strandings (n = 22). No other general tendencies were determined with the existing data.

    2008-01-01

    An improved scalar Costa scheme (SCS) was proposed by using improved Watson perceptual model to adaptively decide quantization step size and scaling factor. The improved scheme equals to embed hiding data based on an actual image. In order to withstand amplitude scaling attack, the Watson perceptual model was redefined, and the improved scheme using the new definition can insure quantization step size in decoder that is proportional to amplitude scaling attack factor. The performance of the improved scheme outperforms that of SCS with fixed quantization step size. The improved scheme combines information theory and visual model.

    In the present work, an assessment of the Physics research capacity in Chile is presented. For this, the period between 2000 and June 2005 has been studied. In this period almost 200 physicists have contributed to scientific production in terms of ISI publications. Amongst these 200, {approx}160 correspond to theoretical physicists and only {approx}40 to experimental physicists; {approx}178 are men and only {approx}22 are women. A more detailed analysis shows that {approx}160 physicists have at least one appearance in ISI publications per year considering the last 3 years. Ten years ago, a similar criteria (at least one appearance per year in ISI articles, considering mobile three-year periods), the number of active physicists in the Chilean community was estimated at 70. Therefore, the Chilean active physicists' community has doubled in 10 years. There exist 20 centres in which scientific research is developed: 18 university centres, a government institute and a private institute. As regards scientific productivity, both as related to disciplines or research areas, and well as in relation to research centres, it is found that, generally, scientific production, in a particular area in Physics or in a research centre, is directly related to the number of corresponding researchers; that is to say, the percentage of the national productivity in an area or research centre corresponds to its share in the total number of physicists in the country. A geographical analysis shows that 50% of the productivity corresponds to Santiago and 50% to the rest of the country. The impact of the different funds for research is assessed, also: FONDECYT, Presidential Chairs and large projects and centres of excellence. According to Physics researchers opinion, Fondo Nacional de Ciencia y TecnologIa (FONDECYT, National Fund fro Science and Technology) has become the best instrument to support researchi activities in Chile. However, the amount of projects awarded has practically not

    Nearly all interplate megathrust earthquakes occur in the seismogenic coupling zone between converging plates. In the area of the 1960 Chile earthquake (Mw = 9.5), we aim at a quantitative understanding of the seismicity and its relation to processes operating at depth and at the surface. As a first step, the offshore experiment SPOC with RV SONNE was combined with an onshore-offshore, active-passive seismic experiment between 36\\deg and 39\\deg S, crossing the rupture area of the 1960 Chile earthquake. The campaign comprised: (1) a 2-D wide-angle component recording chemical shots and airgun pulses along three consecutive E-W onshore profiles; (2) a seismic reflection experiment in the onshore-offshore transition; and (3) a 3-D component which recorded both active and passive sources. Offshore, the upper plate is split into many segments with pronounced forearc basins and a narrow accretionary wedge. A thick subduction channel seems to cause a non-frontally accreting subduction mode. Along the westernmost part of the southernmost E-W refraction seismic line, the profile spread of the active reflection seismic survey at 38\\deg 15' S was 54 km long, and also recorded the airgun shots of the marine profile with the first 18 km of its spread. Different mainly eastward dipping reflection bands are observed. Between 5-25 km depth the internal structure of the Palaeozoic accretionary wedge is described. Reflections between 16-42 km correlate with Wadati-Benioff seismicity and are interpreted as imaging the top of the downgoing plate. In the central part of the profile a break in reflectivity located below the axis of the coastal cordillera more or less coincides with the intersection between the oceanic plate and the continental Moho. This break in reflectivity also approximately correlates with the downdip end of the seismogenic plate interface as defined by geodetic modelling. These new seismic data provide the geometry of the subduction zone in the area, and hence

Se encontró un total de 15 especies de corales (11 hermatípicas y 4 ahermatípicas, las que sumadas a informes previos para el parque hacen un total de 18 especies. El coral Porites lobata presentó la mayor cobertura coralina (36.5 ± 3.7% y fue el único presente en todos los sitios. Las otras especies de coral presentaron bajas coberturas (<10% y sólo fueron observadas en pocos sitios. El porcentaje de coral muerto fue de 1.8 ± 0.6% y el porcentaje de blanqueamiento (0.7 ± 0.2% está dado por P. lobata en un solo sitio. El PNMB y la Isla del Caño poseen el mayor número de especies de coral (18 especies de la región sur de Costa Rica; sin embargo, difieren en su composición. La baja diversidad y la baja cobertura coralina de varios sitios del parque se atribuyen al impacto del fenómeno de El Niño en los últimos años, a la sedimentación y a la dilución de las aguas en época de lluvias. Se sugiere la necesidad de realizar un monitoreo a largo plazo sobre estos ecosistemas y determinar futuras estrategias de manejo y conservación.

    endemismo, tanto para la costa de Chile, como para el Pacífico Suroriental. Determinamos el número y porcentaje de taxa de peces pertenecientes a cuatro grupos según sus afinidades biogeográficas. Esta asignación a grupos se hizo al nivel de especie, género y familia, tanto para teleosteos como condrictios. Con el fin de determinar la existencia de regiones biogeográficas, utilizamos análisis de conglomerados y ordenación en conjunto con técnicas de aleatorización, para los tres niveles taxonómicos estudiados. Se determinó que la diversidad de peces litorales se mantiene relativamente constante a lo largo de la costa, hasta alrededor de los 40º S, disminuyendo hacia el sur. Detectamos dos regiones biogeográficas a lo largo de la costa chilena, con un quiebre entre ellas a los 40º S. Estos resultados apoyan la existencia de las provincias biogeográficas o unidades faunísticas reconocidas previamente en la literatura. Estas dos regiones biogeográficas reflejan el origen mixto de la ictiofauna litoral chilena, la que consiste de especies de peces de origen subtropical y subantartico. Aunque el porcentaje de peces endémicos a la costa chilena es bajo (18%, un alto porcentaje de las especies de teleosteos presentes en aguas chilenas es endémico al Pacífico Suroriental (44%. Procesos relacionados con fenómenos de dispersión y la historia evolutiva de los componentes de esta fauna explicarían de mejor manera los patrones de distribución observados más que otros factores sugeridos en la literatura. Este estudio representa un primer paso hacia una mejor comprensión de la biogeografía de los peces marinos del Pacífico Suroriental

    This paper contributes to the debate about climate change technology transfer by analysing barriers and enablers for a Chilean company starting up the production of wind blades. Literature on the role of technology transfer for the development and deployment of local renewable energy technologies in developing countries often refers to success stories in Brazil, India and China. Instead, this case study highlights the different challenges faced by smaller emerging economies. The paper argues that successful technology transfer in a smaller economy like Chile requires: a minimum internal demand and access to regional markets to attract foreign knowledge providers; a focus in the types of technologies where the recipient country or company have a competitive advantage; and active learning processes by the recipient company. Lessons are drawn for improving the design and implementation of technology-push and market-pull policies in small or medium emerging economies. - Highlights: > We analyse the case of a Chilean company starting up wind blades production. > Technology transfer is required as the relevant knowledge is not available in the country. > We examine the factors that enable technology transfer to draw policy conclusions. > We highlight the particularities of medium sized developing countries.

Assessing both how the Chilean government has converged with the export sector and how the government has been able to co-opt, soften and divide those on the losing side of any FTA policy, are key to understanding Chile's vast number of FTAs. However, FTAs are also a constitutive part of a country's foreign policy, which converts these accords into a vehicle for the achievement of state goals dealing with economic issues and power configurations and expectations. It is the interplay between domestic groups' interests and the state's foreign policy goals that explain Chile's rush to FTAs.Este artículo analiza las razones que llevan a Chile a implementar una política agresiva de Tratados de Libre Comercio (TLC.

    Full Text Available Global catches of marine fishery resources declined during the last decades; however, there has been a trend of increasing exploitation of deepwater resources that are especially vulnerable to depletion. Such a tendency was noticeable in Pacific Latin América, too. In Costa Rica, the vast majority of the commercial fishing activities are concentrated on the Pacific coast. The target species for the deepwater fishery in Costa Rica are the two pandalids Heterocarpus affinis and H. vicarius as well as Solenocera agassizii, the latter one being the most important in terms of annual landings. Here we compile the information available from Costa Rica about each of the three target species. Furthermore, we describe research activities related to the Costa Rican deepwater resources and present available data about by-catch and discards in this fishery. Finally, the current situation of the administration and management of these resources in Costa Rica is described. Strengthening collaboration between governmental agencies, the fishery sector, non-governmental organizations, and the academic sector is recommended to avoid an uncontrolled overfishing of these valuable deepwater resources along the Pacific coast of Costa Rica.Las capturas globales de los recursos marinos pesqueros disminuyeron durante las últimas décadas. Sin embargo, se ha observado una tendencia de aumento en la explotación de los recursos de aguas profundas, los cuales son especialmente vulnerables a la extracción.

    Full Text Available Most of human aggressive behavior occurs in the context of a romantic relationship. Adolescents are not an exception: research show a significant prevalence of dating violence, revealing the need for further study, especially in Latin America, given the lack of research on this topic. This study aims at strengthening knowledge about aggressive behavior in adolescent dating relationships in Costa Rica, taking into account different aggressive behaviors, not only physical or sexual abuse; differences by gender are also analyzed. Based on an ex post facto design, a standardized instrument was used to measure five types of aggressive behavior (i.e., verbal-emotional, physical, sexual, relational and threats in a sample of 468 adolescents from Heredia (Costa Rica. Results show that most participants had committed or suffered aggressions in dating relationships, especially verbal-emotional or both verbal-emotional and sexual abuse, but the mean frequency of reported aggression was low; some significant intersex differences were also found. Results obtained indicate that adolescents have difficulties to deal with conflicts in their romantic relationship; thus this problem needs to be addressed holistically in order to increase the impact of prevention programs for youth.

    The introduction to this report of a study that examines the potential environmental impacts of labor force growth (LFG) in Costa Rica under LFG scenarios notes that LFG is an economically critical aspect of population growth that can affect the environment by expanding the economy's production possibilities frontier and/or by increasing consumption. The introduction also explains why Costa Rica is ideal for this study and identifies the study as unique because it constructs a computable general equilibrium (CGE) model using 10 environmental indicators and because it models uncertainty regarding the values of the economic parameters. The report continues by reviewing the literature linking population and environmental issues; detailing the CGE model; discussing the 10 environmental indicators (deforestation, erosion, pesticide use, overfishing, hazardous wastes, inorganic wastes, organic wastes, greenhouse gas emissions, air pollution, and water/sewer usage) used in the model; and explaining the method used to simulate the impacts of LFG. The major conclusions that emerged from the results of this study are that 1) the economy-wide impacts of LFG (and, thus, population growth) on the environment are important and vary significantly according to the amounts of physical and human capital present in the labor force and 2) the impacts of LFG vary substantially among environmental indicators.

    Sharks are highly vulnerable to intense and prolonged fishery extraction. This article analyzes the data on shark landings from the artisan fishing fleet on Costa Rica's Pacific coast between 1988 and 1997. The data come from an invoicing system administered by the Costa Rican Fisheries Institute (Instituto Costarricense de la Pesca y Acuacultura, INCOPESCA). Pacific coast shark fishing during the period under study represented approximately 20% of the total national fisheries volume. According to data from the invoicing system, the Northern Pacific region was the most productive, reporting 58% of the shark catch nationwide. Within this region, shark fishing in Papagayo Gulf represented 91% and 53% of the landings by fishery region and nationwide, respectively. The mid-sized and advanced (length of boat > 10 meters) artisan fishing fleets reported 96% of the shark catches in the zone. The study of shark fisheries in the Papagayo Gulf zone is crucial for an understanding of fishery dynamics for this resource at the national level. A monthly chronological series was constructed with the landings in the Papagayo Gulf zone, and a Univariate Box-Jenkins (UBJ) Model was estimated for first-order moving averages MA(1) with a seasonal component of the Yt = lamda(t-1) + gammaS12 + a(t) type.

    Deforestation and changes in land use have reduced the tropical dry forest to isolated forest patches in northwestern Costa Rica. We examined the effect of patch area and length of the dry season on nestedness of the entire avian community, forest fragment assemblages, and species occupancy across fragments for the entire native avifauna, and for a subset of forest dependent species. Species richness was independent of both fragment area and distance between fragments. Similarity in bird community composition between patches was related to habitat structure; fragments with similar forest structure have more similar avian assemblages. Size of forest patches influenced nestedness of the bird community and species occupancy, but not nestedness of assemblages across patches in northwestern Costa Rican avifauna. Forest dependent species (species that require large tracts of mature forest) and assemblages of these species were nested within patches ordered by a gradient of seasonality, and only occupancy of species was nested by area of patches. Thus, forest patches with a shorter dry season include more forest dependent species. PMID:27672498

    The CAREX data system converts national workforce volumes and proportions of workers exposed to workplace carcinogens into numbers of exposed in 55 industrial categories. CAREX was adapted for Costa Rica for 27 carcinogens and seven groups of pesticides. Widespread workplace carcinogens in the 1.3 million workforce of Costa Rica are solar radiation (333,000 workers), diesel engine exhaust (278,000), environmental tobacco smoke (71,000), hexavalent chromium compounds (55,000), benzene (52,000), wood dust (32,000), silica dust (27,000), lead and inorganic lead compounds (19,000), and polycyclic aromatic compounds (17,000). The most ubiquitous pesticides were paraquat and diquat (175,000), mancozeb, maneb, and zineb (49,000), chlorothalonil (38,000), benomyl (19,000), and chlorophenoxy herbicides (11,000). Among women, formaldehyde, radon, and methylene chloride overrode pesticides, chromium, wood dust, and silica dust in numbers of exposed. High-risk sectors included agriculture, construction, personal and household services, land and water transport and allied services, pottery and similar industries, woodworks, mining, forestry and logging, fishing, manufacturing of electrical machinery, and bar and restaurant personnel.

    Full Text Available Un sector interesante al que aplicar nuevas categorías de la investigación histórica y social es, sin duda, el de la educación de las mujeres. Maestras, educadoras, pedagogas fueron revolucionarias en diversas épocas de la historia dedicando su existencia a la difusión de conocimientos que pudiesen ser aprovechados por otras mujeres. Para ello fundaron escuelas, escribieron libros y publicaron periódicos. En este sentido las maestras socialistas italianas fueron pioneras al difundir palabras claves como derechos, democracia e igualdad de sueldo. Una figura muy importante fue la maestra antifascista Alda Costa (1876-1944, que luchó contra el militarismo italiano antes de la Primera Guerra Mundial y asumió encargos de gran relevancia en el Partido Socialista. Además fue amiga de Giacomo Matteotti, asesinado por los fascistas en Roma en junio de 1925. Alda Costa fue encarcelada, por su oposición al régimen, y los sufrimientos padecidos precipitaron su muerte.

    Bats are hosts of diverse coronaviruses (CoVs) known to potentially cross the host-species barrier. For analysing coronavirus diversity in a bat species-rich country, a total of 421 anal swabs/faecal samples from Costa Rican bats were screened for CoV RNA-dependent RNA polymerase (RdRp) gene sequences by a pancoronavirus PCR. Six families, 24 genera and 41 species of bats were analysed. The detection rate for CoV was 1%. Individuals (n = 4) from four different species of frugivorous (Artibeus jamaicensis, Carollia perspicillata and Carollia castanea) and nectivorous (Glossophaga soricina) bats were positive for coronavirus-derived nucleic acids. Analysis of 440 nt. RdRp sequences allocated all Costa Rican bat CoVs to the α-CoV group. Several CoVs sequences clustered near previously described CoVs from the same species of bat, but were phylogenetically distant from the human CoV sequences identified to date, suggesting no recent spillover events. The Glossophaga soricina CoV sequence is sufficiently dissimilar (26% homology to the closest known bat CoVs) to represent a unique coronavirus not clustering near other CoVs found in the same bat species so far, implying an even higher CoV diversity than previously suspected.

    Many countries in the Americas describe themselves as "nations of immigrants." In the United States, the myth of the "promised land" suggests that foreigners better themselves upon arrival because the nation is intrinsically great. In Brazil, however, the relationship between immigration and national identity is different. Many intellectuals, politicians, and cultural and economic leaders saw (and see) immigrants as improving an imperfect nation that has been tainted by the history of Portuguese colonialism and African slavery. As a result, immigrants were often hailed as saviors because they modified and improved Brazil, not because they were improved by Brazil. This "improvement" took place through absorption, mixture and with the use of increasingly flexible racial and ethnic categories.

    Despite of its small size, the Central American country of Costa Rica is internationally recognized as one of the world leaders in conservation and as the Central American leader in science. There have been no recent studies on the country's scientific production. The objective of this study was to analyze the Costa Rican scientific output as represented in the Science Citation Index Expanded. All documents with "Costa Rica" in the address field from 1981 to 2010 were included (total 6 801 publications). Articles (79%) were more frequent than other types of publication and were mostly in English (83%). Revista de Biología Tropical published the most articles (17%), followed by Toxicon and Turrialba (2.5%). The New England Journal of Medicine had the highest impact factor (53.484) with nine articles. Of 5 343 articles with known institutional address, 63%were internationally collaborative articles (most with the USA) with h index 91 and citation per publication 18. A total of 81% of all articles were inter-institutionally collaborative articles, led by the Universidad de Costa Rica. This reflects research and education agreements among these countries. Universidad de Costa Rica ranked top one in inter-institutionally collaborative articles, the rank of the total inter-institutionally collaborative articles, and the rank of first author articles and corresponding author articles. Studied subjects and journals in our sample are in agreement with dominant science fields and journals in Costa Rica. Articles with the highest citation were published in New England Journal of Medicine. The largest citation of medical articles reflects the general interest and wider readership of this subject. All corresponding and first authors of the high impact articles were not from Costa Rica. In conclusion, the scientific output of Costa Rican authors is strong in the areas related to conservation but the impact is higher for biomedical articles, and Costa Rican authors need to

    This article focuses on scientific integrity and the identification of predisposing factors to scientific misconduct in Brazil. Brazilian scientific production has increased in the last ten years, but the quality of the articles has decreased. Pressure on researchers and students for increasing scientific production may contribute to scientific misconduct. Cases of misconduct in science have been recently denounced in the country. Brazil has important institutions for controlling ethical and safety aspects of human research, but there is a lack of specific offices to investigate suspected cases of misconduct and policies to deal with scientific dishonesty.

    Lippia alba (Verbenaceae) is a shrub whose essential oil has important biological, pharmacological, and aromatizing properties. The species has a natural range from Central America to Argentina, being cultivated for its commercial value in Brazil, Argentina and Guatemala, and has been introduced into India and Spain. To reach the economic potential of the plant, the present study was aimed at evaluating L. alba for different chemotypes. The composition of the essential oil from two native populations of L. alba, collected from Argentina and two accessions from Costa Rica, were screened by GC and GC-MS. The results obtained led us to adopt the concept of a biodistribution map, as was proposed previously for the species, representing an approach to the natural biological distribution of the species in America based on the chemotypes described and their geographical distribution. Moreover, the biodiversity reported for the species (seven of eight chemotypes described for L. alba are present in Argentina) suggests the southern region of South America as the centre of distribution for L. alba.

    Observing sites at the East-Antarctic plateau are considered to provide exceptional conditions for astronomy. The aim of this work is to assess its potential for detecting transiting extrasolar planets through a comparison and combination of photometric data from Antarctica with time series from a midlatitude site. During 2010, the two small aperture telescopes ASTEP 400 (Dome C) and BEST II (Chile) together performed an observing campaign of two target fields and the transiting planet WASP-18b. For the latter, a bright star, Dome C appears to yield an advantageous signal-to-noise ratio. For field surveys, both Dome C and Chile appear to be of comparable photometric quality. However, within two weeks, observations at Dome C yield a transit detection efficiency that typically requires a whole observing season in Chile. For the first time, data from Antarctica and Chile have been combined to extent the observational duty cycle. This approach is both feasible in practice and favorable for transit search, as it i...

    2012-09-06

    Chile has experienced several serious energy supply incidents over the last decade, including major droughts, a sustained gas supply cut from Argentina (since 2004), and a major earthquake in early 2010 which affected electricity networks and refineries, and caused several black-outs. Due to Chile's unique and sinuous geography - it runs 4 300 kilometres from North to South and only 175 kms from East to West- the country's energy markets are regionally disjointed, particularly as the regional gas and electricity grids are not connected. In the arid North, energy demand is dominated by the mining industry, and operates based on a separate thermal-based Sistema Interconectado Norte Grande (SING) electricity grid. The more densely-populated central region (including Santiago) operates on the more hydro-dependent Sistema Interconectado Central (SIC) electricity grid. The southernmost, hydro-rich regions of the country are not connected to the rest of Chile in terms of electricity and gas. The following report is based on an IEA Emergency Response Assessment carried out in 2010 and 2011 which looked specifically at Chile's capacity to respond to short-term emergencies in oil, gas and electricity.

    Zhu, Xiao-San; Lu, Min-Jie

    2016-12-01

    Chile is a very important country that forms part of the Andean metallogenic belts. The Atacama and Domeyko fault systems in northern Chile control the tectonic-magmatic activities that migrate eastward and the types of mineral resources. In this paper, we processed and interpreted aeromagnetic data from northern Chile using reduction to pole, upward field continuation, the second derivative calculation in the vertical direction, inclination angle calculation, and analytical signal amplitude analysis. We revealed the locations and planar distribution characteristics of the regional deep faults along the NNE and NS directions. Furthermore, we observed that the major reasons for the formation of the tectonic-magmatic rocks belts were the nearly parallel deep faults distributed from west to east and multiple magmatic activities along these faults. We ascertained the locations of volcanic mechanisms and the relationships between them using these regional deep faults. We deduced the spatial distributions of the basic-intermediate, basic, and acidic igneous rocks, intrusive rocks, and sedimentary sequences. We showed the linear positive magnetic anomalies and magnetic anomaly gradient zones by slowly varying the background, negative magnetic anomaly field, which indicated the presence of strong magmatic activities in these regional deep faults; it also revealed the favorable areas of copper and polymetallic mineralization. This study provides some basic information for further research on the geology, structural characteristics, and mineral resource prospecting in northern Chile.

    Science.gov (United States)

    Espinoza, Manuel Antonio; Cabieses, Báltica; Paraje, Guillermo

    2014-01-01

    Health research is considered an essential element for the improvement of population health and it has been recommended that a share of the national health budget should be allocated to develop this field. Chile has undertaken efforts in the last decades in order to improve the governmental structure created to promote the development of health research, which has increased human resources and funding opportunities. On the other hand, the sustained economic growth of Chile in the last decades suggests that the health expenditure will maintain its increasing trend in the following years. This additional funding could be used to improve coverage of current activities performed in the health system, but also to address the incorporation of new strategies. More recently, health technology assessment (HTA) has been proposed as a process to support decisions about allocation of resources based on scientific evidence. This paper examines the relationship between the development of health research and the HTA process. First, it presents a brief diagnosis of the situation of health research in Chile. Second, it reviews the conceptual basis and the methods that account for the relationship between a HTA process and the development of health research. In particular, it emphasizes the relevance of identifying information gaps where funding additional research can be considered a good use of public resources. Finally, it discusses the challenges and possible courses of action that Chile could take in order to guarantee the continuous improvement of an articulated structure for health research and HTA.

    Full Text Available Este trabajo sitúa el problema de la guerra del Acre en un contexto multilateral, reconociendo la vigencia del equilibrio de poder como parte del razonamiento de la conducción de las políticas exteriores en juego. Se aplica el concepto de frontera de F. J. Turner, para explicar cómo las fronteras permeables pusieron a Brasil y Bolivia en confrontación, por la maniobra boliviana de configurar una concesión a inversionistas estadounidenses, británicos y franceses, que fue interpretada por Brasil como una maniobra imperialista de Estados Unidos. Entones Brasil se acercó a Chile, y afrontaron juntos los problemas del Acre y de Antofagasta, que derivaron en las redacciones de los tratados de Petrópolis (1903 y de Paz y Amistad (1904. El artículo postula que Bolivia procedió de esta forma para impedir el avance brasileño, peruano y paraguayo sobre sus fronteras, y que la búsqueda del paraguas estadounidense fue una idea que Bolivia gestó para compensar el desequilibrio de poder.This work considers the Acre War as part of a multilateral context where the equilibrium of power was important in the reasoning behind the establishment of foreign relations. It uses the frontier concept developed by F. J. Turner to explain why their open frontier put Brazil and Bolivia in confrontation. This happened because of the Bolivian strategy of granting land to investors from the United States, Great Britain and France, which was interpreted by Brazil as an imperialist action promoted by the United States. This explains why Brazil established a cióse relationship with Chile to confront together their problems in Acre and Antofagasta, which led to the drafting of the Petrópilis (1903 and Paz y Amistad (1904 treaties. The article argues that Bolivia proceeded this way to avoid a Brazilian, Peruvian or Paraguayan territorial advance, seeking the support of the United States to compénsate the imbalance of power.

    Brazil is one of the world's largest economies and the country also has significant heavy oil reserves. This report from the National Petroleum Agency of Brazil aims at presenting the situation of the oil and gas sector in Brazil in terms of resources, production, regulatory framework and opportunities for the future. Brazil has numerous sedimentary basins at its disposal, most of them being prospected by both national and foreign companies from all over the world. Brazil has over 14 billion barrels of proven reserves, its production is 2,1 MMBbl/d and heavy oil represents almost 40% of that production. The National Petroleum Agency of Brazil is responsible for the implementation of oil sector policy with the aims of maintaining self-sufficiency, implementing good practices in terms of health and safety, and increasing local content. This paper pointed out that Brazil has an important opportunity to enhance its energy sector through the development of heavy oil.

    2015-01-01

    Full Text Available This study aimed to show, based on the literature on the subject, the potential for dispersal and establishment of the chikungunya virus in Brazil. The chikungunya virus, a Togaviridae member of the genusAlphavirus, reached the Americas in 2013 and, the following year, more than a million cases were reported. In Brazil, indigenous transmission was registered in Amapa and Bahia States, even during the period of low rainfall, exposing the whole country to the risk of virus spreading. Brazil is historically infested by Ae. aegypti and Ae. albopictus, also dengue vectors. Chikungunya may spread, and it is important to take measures to prevent the virus from becoming endemic in the country. Adequate care for patients with chikungunya fever requires training general practitioners, rheumatologists, nurses, and experts in laboratory diagnosis. Up to November 2014, more than 1,000 cases of the virus were reported in Brazil. There is a need for experimental studies in animal models to understand the dynamics of infection and the pathogenesis as well as to identify pathophysiological mechanisms that may contribute to identifying effective drugs against the virus. Clinical trials are needed to identify the causal relationship between the virus and serious injuries observed in different organs and joints. In the absence of vaccines or effective drugs against the virus, currently the only way to prevent the disease is vector control, which will also reduce the number of cases of dengue fever.

    Full Text Available La trata de personas con fines de explotación sexual comercial es una problemática solapada en Costa Rica. Resulta necesario conocer este fenómeno, puesto que cada día más ciudadanos son atrapados y sometidos a una forma de esclavitud, que denigra su integridad física, psicológica, social y espiritual. A partir de las experiencias vividas como profesional en una organización sin fines de lucro (ONG con un programa para esta población, hizo evidente el desconocimiento y los excesivos prejuicios sobre las víctimas en la sociedad. Se explora el hecho de que la información sobre este fenómeno en Costa Rica es escasa y el abordaje psicológico lo es aún más. La investigación tiene sus bases en la metodología cualitativa descriptiva; se propone un diseño fenomenológico que parte de la teoría humanista del Análisis Transaccional de Berne (1976 para efectuar estudio múltiple de casos. La muestra estuvo constituida por un grupo de cinco mujeres, que se encontraron en proceso de restauración en la ONG bajo las categorías de análisis “Trata de personas con fines de explotación sexual comercial nacional” (dentro de Costa Rica, “Avasallamientos” y “Desarrollo personal”. Los resultados identificaron avasallamientos, a los que fueron sometidas las mujeres de esta muestra, antes, durante y después de ser captadas en la trata. Asimismo, se analiza cómo el desarrollo de las mujeres víctimas de trata en este estudio se ve obstaculizado por dichos avasallamientos y cómo algunas lograron obtener el crecimiento personal a pesar de lo sucedido.

    Full Text Available Este documento ilustra un enfoque económico a la comprensión de la industria de turismo de cruceros como impulsora del desarrollo económico en Costa Rica. El objetivo es describir el papel y las actividades de la industria de cruceros e identificar fuentes de costo y beneficio económico, a fin de que se puedan tomar decisiones locales de política con más información sobre el turismo de cruceros. Por ejemplo, nuestro análisis indica que la industria de turismo de cruceros compite con la industria de despacho de carga por espacio portuario a un significativo costo para los puertos de Costa Rica: la cantidad de dinero inyectada a la economía local por turista de crucero es sustancialmente más baja que para otros tipos de turismo. Los cruceros de turismo compran relativamente pocos suministros en Costa Rica y generan una gran cantidad de desechos producidos por las personas así como contaminación de agua y aire, lo que puede crear un serio peligro para la salud y costos de limpieza que no son proporcionales con otros tipos de desarrollo turístico de los que dispone el país. Quizás los encargados de tomar decisiones quieran considerar que la inversión en puertos amistosos con el turismo de crucero podría ser menos eficiente desde una perspectiva nacional que la inversión en infraestructura (por ejemplo, aeropuertos para aumentar tipos más rentables de turismo. Asimismo, quizás los líderes quieran pensar en estimular cruceros más pequeños “de bolsillo” más bien que la actual versión de turismo masivo. Este método debería ser aplicable a comunidades donde el turismo de crucero existe actualmente o se está considerando para incluirlo en la cartera de actividades económicas comunitarias.

    Morales-Ramírez, A

    2001-12-01

    This report is part of a series that summarizes the species and localities of Costa Rican marine taxa. A review of the literature on copepods, both pelagic and benthic for the Pacific and Caribbean coast of Costa Rica, includes eighty species. Sixty seven pelagic species have been found, distributed between sixteen calanoid, one cyclopoid, three harparticoid and four poecilostomatoid families. Moreover, thirteen benthonic species distributed into six families, all harparticoids, are reported. Among the pelagic families, Pontellidae has six species, while Paracalanidae and Eucalanidae had five each. Other families, like Calanidae, Pseudodiaptomidae and Acartiidae had four species and most families only one. Forty five species are reported only for the Pacific coast, thirteen for the Caribbean coast, only nine species occurred in both coasts; being a direct consequence of the more intensive research effort in the Pacific. Pelagic copepod biodiversity reflects different oceanographic conditions in both coasts. Typical estuarine species were found in the lower region of the Gulf of Nicoya, while a mixture of estuarine and oceanic species were found in Golfo Dulce. Diversity in the Caribbean, specially at the Cahuita coral reef is lower in comparison with the copepod diversity found in other regions in the Caribbean sea. This may be due to the high sediment resuspension rate characteristic of the Cahuita coral reef, which could affect the reproduction of many holozooplankters, specially copepods. Although sixty seven pelagic copepod species appears to be in low numbers, in terms of specific biodiversity it is as high when compared to numbers found in other tropical areas. Thirteen species are reported in the literature, all harparticoids. Five species, three sub-species and one genera were new to science. Balacopsylla is reported for the first time from a neotropical regions, while the genus Karllangia, represented by two coexisting species in the Caribbean coast

    Este folleto contiene historias veridicas que ilustran como sobrevivir, y como no sobrevivir, a un tsunami. Esta publicacion esta dirigida a las personas que viven, trabajan o, simplemente, se divierten a lo largo de las costas que pueden ser afectadas por un tsunami. Tales costas rodean la mayor parte del Oceano Pacifico pero tambien incluyen algunas areas costeras de los Oceanos Atlantico e Indico. Aunque mucha gente llama a los tsunamis 'olas de marea', estos no estan relacionados a las mareas, sino son una serie de olas, o 'tren de olas', generalmente causadas por cambios en el nivel del fondo marino durante los terremotos. Los tsunamis tambien pueden ser generados por la erupcion de volcanes costeros, islas volconicas, deslizamientos submarinos e impactos de grandes meteoritos en el mar. Como sucedio en Sumatra en el 2004, los tsunamis pueden alcanzar alturas de 15 metros, no tan solo en la costa sino tambien kilometros tierra adentro. Los relatos presentados en este folleto fueron seleccionados de entrevistas realizadas a personas que sobrevivieron al tsunami del Oceano Pacifico de 1960. Muchas de estas personas, incluyendo a la enfermera de la foto, se enfrento a las olas generadas a poca distancia, en la costa chilena. En cambio, otros debieron hacer frente al tsunami muchas horas despues, en Hawai y Japon. La mayoria de las entrevistas fueron realizadas a fines de los anos ochenta y en los noventa. Las historias ofrecen una mezcla de lecciones de supervivencia a un tsunami. En algunos casos se presentan las acciones que confiablemente salvaron vidas: poner atencion a los avisos de la naturaleza, abandonar los bienes, dirigirse rapidamente a un sector alto y permanecer alli hasta que el tsunami realmente haya terminado. Otras historias describen como se encontro refugio al subir a construcciones y arboles o flotar sobre desechos, tacticas que tuvieron diferentes resultados y que pueden ser recomendadas solo como actos desesperados de personas atrapadas en

    Full Text Available Este artículo presenta una visión general de la historia del jazz en Chile que destaca la función social de esta música y el cambio que tuvo a través del tiempo. Estos cambios se relacionaron con diferentes valoraciones de la práctica jazzística local. En un principio el jazz fue música popular masiva. Posteriormente fue valorado estéticamente por un segmento de élite, quienes eran profesionales en áreas no musicales y en muchos casos eran instrumentistas aficionados. En una tercera etapa, músicos profesionales asumieron la práctica del jazz como una plataforma para fusionar el lenguaje jazzístico con recursos tomados de la música tradicional chilena. Este tránsito del jazz en Chile está cruzado por factores socioeconómicos y estéticos, que se analizan en el trabajo.The article presents an overview of the history of jazz in Chile on the basis of the social function of jazz and the changes it has underwent over the years in terms of the valúes it has represented for Chilean society. Initially jazz was considered as mass popular music. Afterwards it was valued in aesthetic terms by a group belonging to the élite of Chilean society. Many of them belonged to non-music professions and in some cases were amateur musicians. Most recently professional musicians took up jazz as the basis for combining the jazz style with elements belonging to traditional music of Chile. This process in Chile is also influenced by social, economic and aesthetic aspects which are explored in this article.

    Full Text Available This observational pilot study was carried out at three sugarcane companies in Costa Rica. Its main objective was to determine the potential for heat stress conditions for workers in one sugarcane-growing region in Costa Rica during the maintenance (non-harvest period.Wet bulb globe temperature (WBGT variables were measured with a heat stress meter and threshold value limits and the Sweat Rate Indexes were calculated for each workplace. It was determined that workers in this study were in heat stress conditions. Costa Rica is likely to experience warmer temperatures and increased heat waves in the coming decades. It is therefore important to take action to decrease current and future heat-related risks for sugarcane workers in both harvest and non-harvest conditions and in all sugarcane growing regions in Costa Rica. It is also necessary to improve guidelines and occupational health standards for protecting worker health and productivity in the tropics.

La idea fundamental contempla al núcleo inflacionario como un indicador de la tendencia subyacente de la inflación capaz de capturar el componente del cambio total de precios común a todos los bienes y servicios, cuya persistencia se mantendría en el mediano y largo plazo y que excluye los cambios en los precios relativos de estos. La medida de núcleo inflacionario seleccionada se contrasta con el Índice de Núcleo Inflacionario (INI, indicador de inflación subyacente actualmente utilizado por el Banco Central de Costa Rica (BCCR.El Índice Subyacente de Inflación (ISI, definido como una medida de núcleo inflacionario que excluye un 30,7% del peso total del Índice de Precios al Consumidor (IPC, refleja más fielmente la tendencia subyacente de la inflación y logra capturar el movimiento más permanente del nivel general de precios, aislando las variaciones en precios relativos. Además, el ISI es fácil de calcular e interpretar lo cual ayuda a incrementar la transparencia y credibilidad de la política monetaria. También es un indicador oportuno, aumentando su valor para los que formulan la política monetaria. Por último, el ISI supera algunas de las limitaciones del INI, como son la falta de un criterio estadístico para definir el punto de corte de los bienes y servicios a excluir y el alto porcentaje del peso total del IPC eliminado. AbstractThis paper builds and evaluates several alternative measures of core inflation for Costa Rica.

    2001-12-01

    The time-space behavior of thermohaline properties of the water masses in the Gulf of Nicoya, a tropical estuary in the Costa Rican Pacific coast, was studied by sampling monthly from April 1992 to April 1993. The saline field has a seasonal maximum during April, a month before the maximum temperature is observed. Minimun values were observed during October and November, in the rainy season. A defined surface saline front is located towards the east of Negritos Islands; it is produced by the interaction of freshwater from the Tarcoles River and the oceanic waters that enter through the occidental coast of the gulf. The vertical distribution of temperature and salinity indicates a gulf whose internal area is highly stratified in the rainy season, and much less stratified, or even well mixed in the dry season. The outer area of the Gulf is stratified throughout the year.

    2011-01-01

    Full Text Available The coccids have different sex-determining mechanisms, including the heterochromatinization haplodiploidy of chromosomes of paternal origin, characteristic of the family Dactylopiidae. The heterochromatinization in coccids seems to be a mechanism by which part of a chromosome, the entire chromosome, or several chromosomes will become genetically inactive during development of the individual. In the first division immediately after fertilization, the chromosomes of embryos appear euchromatic (E; shortly after the blastocyst stage, almost half of the chromosomes become heterochromatic (H in embryos that are destined to be male, while in the female all the chromosomic set remain euchromatic. The objective of this study is to determine the heterochromatinization process in the sex determination of Dactylopius coccus Costa, 1935 embryos. The method used to identify chromosomes has been the conventional 2% lacto-acetic orcein protocol. In D. coccus it was observed that during embryogenesis, heterochromatinization occurs in the set of chromosomes from paternal origin, while those of maternal origin remain euchromatic.

The pattern is that sediment change from inner to mouth of bays. Carbonates and gravel fractions increased offshore and organic matter have high values inner the bays. Input of vegetal debris and mud was from the rivers of this island covered with rain and cloud forest.

  11. Paleozoic evolution of active margin basins in the southern Central Andes (northwestern Argentina and northern Chile)

    Science.gov (United States)

    Bahlburg, H.; Breitkreuz, C.

    The geodynamic evolution of the Paleozoic continental margin of Gondwana in the region of the southern Central Andes is characterized by the westward progression of orogenic basin formation through time. The Ordovician basin in the northwest Argentinian Cordillera Oriental and Puna originated as an Early Ordovician back-arc basin. The contemporaneous magmatic arc of an east-dipping subduction zone was presumably located in northern Chile. In the back-arc basin, a ca. 3500 meter, fining-up volcaniclastic apron connected to the arc formed during the Arenigian. Increased subsidence in the late Arenigian allowed for the accomodation of large volumes of volcaniclastic turbidites during the Middle Ordovician. Subsidence and sedimentation were caused by the onset of collision between the para-autochthonous Arequipa Massif Terrane (AMT) and the South American margin at the Arenigian-Llanvirnian transition. This led to eastward thrusting of the arc complex over its back-arc basin and, consequently, to its transformation into a marine foreland basin. As a result of thrusting in the west, a flexural bulge formed in the east, leading to uplift and emergence of the Cordillera Oriental shelf during the Guandacol Event at the Arenigian-Llanvirnian transition. The basin fill was folded during the terminal collision of the AMT during the Oclóyic Orogeny (Ashgillian). The folded strata were intruded post-tectonically by the presumably Silurian granitoids of the "Faja Eruptiva de la Puna Oriental." The orogeny led to the formation of the positive area of the Arco Puneño. West of the Arco Puneño, a further marine basin developed during the Early Devonian, the eastern shelf of which occupied the area of the Cordillera Occidental, Depresión Preandina, and Precordillera. The corresponding deep marine turbidite basin was located in the region of the Cordillera de la Costa. Deposition continued until the basin fill was folded in the early Late Carboniferous Toco Orogeny. The basin

  12. Health care in Costa Rica: boom and crisis.

    Mesa-Lago, C

    1985-01-01

    In 1960-1980 Costa Rica experienced a health boom, achieving significant improvements which moved that country into the number two position in Latin America for indicators such as population coverage, infant mortality, life expectancy and health services. In addition, there was a gradual process of integration of health services. But in the same period, the cost of health care as a percentage of GNP increased almost 5-fold and in 1980 was the fourth highest in the region. The economic crisis of the 1980s aggravated the financial difficulties; to cope with them, the government introduced an austere program to reduce costs and plans to transform the current model of health care into a more efficient one capable of maintaining Costa Rica's high health standards in the future. The paper is divided into five sections: summary of the historical development of health care, and description of its current organization and of its gradual process of integration; estimation of population coverage and its trends, evaluation of inequalities in coverage, and identification of the non-covered group; analysis of health-care financing and its sources, as well of the recent financial desequilibrium, its causes and measures to restore the equilibrium; description of health care benefits and their differences among groups and regions, analysis of the country's advances in health-care facilities and standards, and measurement of the impact of the health care system in income distribution; and description of the rising cost of health care and the current crisis, analysis of the causes of both phenomena, and review of the measures that have been and should be implemented to solve these problems.

    It is reported the prevalence, magnitude and determinant factors of nutritional anaemia in a sample of nursing women (NW), collected during the National Nutrition Survey, of Costa Rica done in 1996. Nutritional anaemia was determinate through measurements of haemoglobin, and plasma ferritin, folates, cianocobalamin and retinol. Methodologies used were cianometahaemoglobin, solid phase immunoradiometric assay, solid phase radioimmunoassay and high-pressure liquid chromatography. WHO cut-off points were used. Anaemia was present in 22.1% of the women. Iron and folate deficiency were found in 48.7 and 84.2% NW, respectively. The magnitude of anaemia was mild and iron and folate deficiencies were severe. Vitamin B12 and A deficiencies were 5.3 and 4.9%, respectively and did not represent a public health problem in this group. Prevalent deficiency was mixed (iron and folates, 46.6%) followed by exclusive folates deficiency (32%). Anaemia was caused by a combined deficiency of iron and folates (61.1%) and most iron deficiencies were accompanied by folates (92%). The logistic regression analysis demonstrated that low socio-economic level of NW and their families was the principal factor determining the appearance of nutritional anaemia, and educative interventions to the mother are possibly recommended. In conclusion anaemia in NW is a moderate health problem of nutritional type, that is more important when severe folates and iron deficiencies are present in Costa Rica. These problems have remained constant throughout the last three decades; although recently, possibly an improvement has occurred because the prevalence of neural tube defects in the infant population has reduced, maybe due to food iron and folates fortification public health policies implementation.

    The Community Development Association of the fishing village of Barra del Colorado populated by Blacks embraced the Conservation Strategy for the Sustainable Development of the Plains Tortuguero covering 419,000 hectares of lowland rain forest and wetlands along the Caribbean cost of northern Costa Rica. In 1985 the government established the Barra del Colorado Wildlife Refuge. The International Union for the Conservation of Nature (IUCN) team visited families and identified community problems. This resulted in the establishment of a communal bank; a community fisherman's association to help obtain a boat and fishing gear; assistance to help villagers obtain title to their land; a feasibility study of a public transport link to the rest of the country; new chairs for the school; and weekly instead of monthly visits by a doctor. The Tortuguero Strategy endeavors to establish 147,000 hectares of conservation area including the Tortuguero National Park. 5000 people live in the buffer zone and 132,000 live in the neighboring western area. The strategy strives to reverse deforestation in the buffer zone by restoring forest cover to 80% of the area by 2000. The Strategy has funded the Union of Small Agricultural Producers of the Atlantic to train people in ecotourism, forestry management, and growing and selling medicinal plants. The IUCN evaluated the environmental impact of expanding banana plantations and recommended ameliorative steps which have not been implemented. The preparation of the Tortuguero Strategy started in 1990 in concert with the Natural Resources Ministry, IUCN, and the European Community. A 1992 draft document based on biophysical, socioeconomic, and legal studies is waiting for official approval. Community strategies have been launched in 2 communities, self-sustaining financing is delayed, and a draft law setting up the conservation area awaits Costa Rican legislative authorization. The strategy is for the long term, but the experience of Barra del

    Full Text Available La Fiebre Manchada de la Montañas Rocosas es una zoonosis transmitida por garrapatas y causada por una bacteria intracelular obligatoria, la Rickettsia rickettsii. Es una enfermedad sistémica, de moderada a severa, producida por la infección del endotelio vascular de pequeños vasos de la mayoría de órganos y tejidos. Es la más letal de las infecciones transmitidas por garrapatas y desde su descubrimiento, hace cerca de 100 años, todavía se presenta, aunque esporádicamente, de forma persistente, y a pesar de que se cuenta con antibióticos efectivos, la mortalidad sigue siendo de mas del 10% y los pacientes requieren terapia intensiva durante la infección si esta no es diagnosticada y tratada a tiempo. En tiempo recientemente se han descrito otras especies de garrapatas que pueden transmitir rickettsias a humanos así como nuevas especies de rickettsias que pueden producir cuadros de fiebres manchadas y aunque se ha dilucidado parte de sus mecanismos patogénicos, persisten muchas dudas respecto a su virulencia. Desde 1975 se han reportado brotes de esta enfermedad en Costa Rica y el agente etiológico causal, la Rickettsia rickettsii, fue aislada e identificada en la mayoría de los casos en el Laboratorio de Virología de la Facultad de Microbiología de la Universidad de Costa Rica.

  16. Partitioning of Seismogenic Strain in the Offshore Costa Rica Forearc

    We examine non-recoverable strain in the offshore forearc crust between the Osa and Nicoya Peninsulas of Costa Rica. Treating the crust as a micropolar continuum we use new and published earthquake focal mechanisms to invert for best-fitting partial strain-rate tensors. Our preliminary results for new focal mechanisms west northwest of the Osa Peninsula indicate a shallow northwest-plunging maximum stretching axis and a subvertical minimum stretching axis. This strain geometry suggests thinning of the forearc and extension nearly parallel to the Middle America Trench. The earthquakes used to constrain this deformation geometry occurred at depths less than 5.1 kilometers in hanging wall crust adjacent to substantial topographic relief on the downgoing Cocos plate. To date evidence for trench-parallel stretching has only come from observations of brittle faults in coastal and inland exposures in Miocene sediments and Quaternary fluvial deposits. Our inversions of existing data from southeast of the Nicoya Peninsula yield results that are in accord with previous findings. Here, events ranging in depth between about 12 and 31 kilometers indicate nearly trench-normal shortening and crustal thickening. Earthquakes at similar depths just west northwest of the Osa Peninsula, however, reveal subhorizontal maximum and minimum stretching axes with the former trending south. This strain geometry is consistent with strike slip faulting and suggests partitioning of seismogenic strain with depth in the forearc offshore Osa Peninsula. In total, our findings suggest variations in the 3-dimensional pattern of non-recoverable strain in the Costa Rica forearc. A quantitative description of this sort of variation is necessary in order to better understand geodetic observations, and ultimately, the relation between coupling across the seismogenic zone and forearc strain.
