    Full Text Available OBJETIVOS: Avaliar a composição de ácidos graxos do leite humano maduro de mulheres residentes em área distante da costa litorânea brasileira. MÉTODOS: Amostras de leite materno maduro foram obtidas de 47 mulheres lactantes com idade entre 18 e 35 anos, que tiveram partos a termo e em aleitamento exclusivo ou predominante. A coleta de leite se deu a partir da 5ª semana pós-parto, por meio de ordenha manual. A composição de ácidos graxos do leite foi determinada por cromatografia gasosa. RESULTADOS: Verificou-se que a concentração de eicosapentaenoico (0,08% foi superior ao observado em estudos brasileiros prévios. Entretanto, o teor de docosahexaenoico (0,09% encontrado no leite humano foi um dos menores já verificados no mundo. O teor de ácidos graxos trans (2,05% foi similar ao relatado em estudos nacionais prévios à obrigatoriedade de declaração do teor deste em rótulos de alimentos, sugerindo que esta medida não surtiu efeito na redução de seu teor na dieta habitual das mulheres. CONCLUSÕES: Baixo teor de docosahexaenoico e elevada concentração de ácidos graxos trans foram verificados no leite materno maduro de mulheres residentes em área distante da costa litorânea brasileira.

    Full Text Available A ocorrência de naufrágios pode ser atribuída a vários fatores. Contudo, embarcações de pequeno porte usadas na pesca costeira, são geralmente mais suscetíveis aos fatores meteorológicos e oceânicos. O objetivo desse estudo foi analisar o comportamento da velocidade do vento e altura significativa de onda em relação à ocorrência de naufrágios na costa brasileira, entre os estados de Sergipe e Rio Grande do Sul. As frequências trimestral e mensal de naufrágios registrados entre Janeiro/2004 e Junho/2008 foram comparados com os ventos e com a altura significativa de ondas. As velocidades médias e máximas do vento nos dias e áreas de ocorrência, bem como a altura significativa de onda, foram comparadas aos valores históricos dessas variáveis. Foram observados ventos e ondas acima da climatologia em 54% e 46% das ocorrências de naufrágio, respectivamente. Em vários casos, o vento atingiu velocidades muito elevadas, sendo a provável causa para a ocorrência desses naufrágios. Os resultados apontaram para uma maior incidência de naufrágios em ambientes costeiros das regiões sudeste e sul do Brasil, com maior ocorrência entre os meses de março e agosto, envolvendo principalmente embarcações de pequeno porte (94%, utilizadas na pesca costeira. Os resultados encontrados reforçam a necessidade do envio de informações meteorológicas e oceanográficas para pequenas embarcações, em especial àquelas empregadas na atividade de pesca costeira.

  6. Feições Oceanográficas em Imagens MODIS na Condição de Sunglint: Exemplos para a Costa Sudeste Brasileira

    Full Text Available Resumo Imagens ópticas e no infravermelho-próximo adquiridas por sensores remotos em condição de reflexão especular bidirecional entre o sol, a superfície do mar e o sensor (condição de sunglint podem ser utilizadas para identificar filmes, feições, processos oceanográficos e meteorológicos atuantes sobre a superfície marinha. Imagens do sensor orbital Moderate Resolution Imaging Spectroradiometer (MODIS em condição de sunglint na plataforma continental sudeste brasileira foram processadas e analisadas, permitindo identificar feições como a borda Oeste da Corrente do Brasil, meandramentos e vórtices de mesoescala, ondas internas solitárias, rolos atmosféricos e filmes superficiais de origem biogênica e mineral. Uma correção atmosférica mais apropriada para detecção de feições no sunglint é aprensentada, assim como, detalhes sobre a geometria de aquisição. A dependência geométrica do sunglint torna sua ocorrência mais favorável entre outubro e fevereiro na região de estudo quando ocorrem zênites solares mais propícios. Os mecanismos e processos que permitem identificar estas feições no sunglint foram descritos e ilustrados. A partir deste entendimento, as complexas feições identificadas podem ser interpretadas e aplicadas na oceanografia operacional e detecção de vazamentos de óleo na superfície do mar, bem como, para melhorar nosso entendimento sobre os processos físicos e biológicos do meio marinho.

    Full Text Available Muitas espécies de bromélias armazenam água da chuva em seu interior, sendo esta característica resultado da distribuição espiralada de suas folhas, que formam pequenos tanques. O objetivo deste estudo foi avaliar e comparar o volume de água efetivamente armazenado e o volume máximo que pode ser armazenado no tanque de diferentes espécies de bromélias de 13 restingas brasileiras. Em cada restinga, em 100 plots de 100 m² cada, registramos as espécies de bromélias-tanque, os parâmetros morfométricos e o volume efetivo e máximo em 20 indivíduos de cada espécie. Encontramos 32 espécies de bromélias-tanque, para as quais medimos o volume máximo e o volume efetivo de água armazenado. Em 59.007 rosetas, estimamos o volume máximo em 44.388 litros e medimos 17.000 litros de água efetivamente armazenados. Encontramos diferenças interespecíficas nos volumes máximo e efetivamente reservado de água, na biomassa, no número de folhas e no volume do cone da planta. Aechmea aquilega, A. blanchetiana e Hohenbergia castelanosii tiveram os maiores volumes efetivos. Somente A. nudicaulis e Billbergia amoena diferiram entre suas populações em todos os parâmetros analisados. As restingas de Maricá, Prado, Trancoso e Jurubatiba tiveram os maiores volumes de água.ha-1 armazenada nas bromélias-tanque. O volume máximo de água estimado para as bromélias-tanque variou entre espécies devido a diferenças na forma e no tamanho das bromélias.Many bromeliad species store rain water in tanks, as a result of the spiraled distribution of their leaves. The aim of this study was to evaluate how much water is stored and what is the maximum volume of water possible to be stored in different tank-bromeliad species in 13 different Brazilian restingas. The species were recorded in 100 plots of 100 m2, in each restinga habitat. For each bromeliad species, the effective and the maximum water stored in the tanks were measured. We found 32 tank

Assim como existe um modo bastante próprio de abordar as questões filosóficas em alguns países, o que nos leva a conceber – através das diferenças evidentes – a existência de uma filosofia francesa, de uma filosofia alemã, inglesa, italiana, e, depois da globalização, de uma filosofia japonesa, árabe, e de outras nações cujas culturas são distintas da judaico-cristã; parece-me pertinente a questão: as singularidades de nosso pais podem produzir um pensamento original ao ponto de configurar um pensamento filosófico brasileiro? E ainda, encontramo-nos capazes, com nossa formação filosófica, de sermos intérpretes do Brasil?

    Full Text Available A viticultura brasileira nasceu com a chegada dos colonizadores portugueses, tornando-se uma atividade comercial a partir do início do século XX. Houve absoluto predomínio do cultivo de uvas americanas até meados do século XX, quando se iniciou o plantio de videiras europeias. Até a década de 1960, a viticultura brasileira ficou limitada às regiões Sul e Sudeste. A partir daí, a uva alastrou-se como alternativa econômica em diversas regiões tropicais do País e ganhou nova dimensão nas zonas temperadas de cultivo. Atualmente, a área vitícola brasileira situa-se ao redor de 83.700 ha, com uma produção anual oscilando entre 1.300.000 e 1.400.000 toneladas. Destacam-se, pelo volume de produção, os Estados do Rio Grande do Sul, São Paulo, Pernambuco, Paraná, Bahia, Santa Catarina e Minas Gerais. A grande maioria das uvas e seus derivados são consumidos no mercado interno. O suco de uva concentrado e a uva de mesa são os principais produtos de exportação. A diversidade é a marca da viticultura brasileira: são diferentes condições ambientais, variados sistemas de cultivo e recursos genéticos com ampla variabilidade. Neste trabalho, é traçado o perfil da viticultura brasileira e são apresentados os principais avanços tecnológicos obtidos nas últimas décadas. Entre outros tópicos, destacam-se a criação de novas cultivares, o desenvolvimento de técnicas e sistemas de manejo da videira - especialmente para as zonas tropicais e o desenvolvimento de sistemas de certificação de produtos vitivinícolas.

  16. The Porifera Ontology (PORO): enhancing sponge systematics with an anatomy ontology.

    Porifera (sponges) are ancient basal metazoans that lack organs. They provide insight into key evolutionary transitions, such as the emergence of multicellularity and the nervous system. In addition, their ability to synthesize unusual compounds offers potential biotechnical applications. However, much of the knowledge of these organisms has not previously been codified in a machine-readable way using modern web standards. The Porifera Ontology is intended as a standardized coding system for sponge anatomical features currently used in systematics. The ontology is available from http://purl.obolibrary.org/obo/poro.owl, or from the project homepage http://porifera-ontology.googlecode.com/. The version referred to in this manuscript is permanently available from http://purl.obolibrary.org/obo/poro/releases/2014-03-06/. By standardizing character representations, we hope to facilitate more rapid description and identification of sponge taxa, to allow integration with other evolutionary database systems, and to perform character mapping across the major clades of sponges to better understand the evolution of morphological features. Future applications of the ontology will focus on creating (1) ontology-based species descriptions; (2) taxonomic keys that use the nested terms of the ontology to more quickly facilitate species identifications; and (3) methods to map anatomical characters onto molecular phylogenies of sponges. In addition to modern taxa, the ontology is being extended to include features of fossil taxa.

    Few surveys on benthic fauna have been performed on the island of Madeira (Alves et al. 2003 and references therein), and the first sponge specimens were collected opportunistically (Johnson 1863, 1899; Topsent 1904, 1928). Porifera can be considered one of the least studied phyla in the Madeira archipelago, within the Lusitanian province. This is not the case for other regions as the Mediterranean (Boury-Esnault 1971 and references therein), Alboran Sea (Carballo 1994), Canary Islands (Cruz 2002), and the Azores (Topsent 1904; Boury-Esnault Lopes 1985; Xavier 2009), where sponges have been more thoroughly studied.

    2009-01-01

    Sponges [porifera], the most ancient metazoans, contain modules related to the vertebrate immune system, including the 2',5'-oligoadenylate synthetase (OAS). The components of the antiviral 2',5'-oligoadenylate (2-5A) system (OAS, 2'-Phosphodiesterase (2'-PDE) and RNAse L) of vertebrates have not all been identified in sponges. Here, we demonstrate for the first time that in addition to the OAS activity, sponges possess a 2'-PDE activity, which highlights the probable existence of a premature 2-5A system. Indeed, Suberites domuncula and Crella elegans exhibited this 2-5A degrading activity. Upon this finding, two out of three elements forming the 2-5A system have been found in sponges, only a endoribonuclease, RNAse L or similar, has to be found. We suspect the existence of a complex immune system in sponges, besides the self/non-self recognition system and the use of phagocytosis and secondary metabolites against pathogens.

  4. Molecular Phylogeny of the Astrophorida (Porifera, Demospongiae p) Reveals an Unexpected High Level of Spicule Homoplasy

    2011-01-01

    Background The Astrophorida (Porifera, Demospongiae p) is geographically and bathymetrically widely distributed. Systema Porifera currently includes five families in this order: Ancorinidae, Calthropellidae, Geodiidae, Pachastrellidae and Thrombidae. To date, molecular phylogenetic studies including Astrophorida species are scarce and offer limited sampling. Phylogenetic relationships within this order are therefore for the most part unknown and hypotheses based on morphology largely untested. Astrophorida taxa have very diverse spicule sets that make them a model of choice to investigate spicule evolution. Methodology/Principal Findings With a sampling of 153 specimens (9 families, 29 genera, 89 species) covering the deep- and shallow-waters worldwide, this work presents the first comprehensive molecular phylogeny of the Astrophorida, using a cytochrome c oxidase subunit I (COI) gene partial sequence and the 5′ end terminal part of the 28S rDNA gene (C1-D2 domains). The resulting tree suggested that i) the Astrophorida included some lithistid families and some Alectonidae species, ii) the sub-orders Euastrophorida and Streptosclerophorida were both polyphyletic, iii) the Geodiidae, the Ancorinidae and the Pachastrellidae were not monophyletic, iv) the Calthropellidae was part of the Geodiidae clade (Calthropella at least), and finally that v) many genera were polyphyletic (Ecionemia, Erylus, Poecillastra, Penares, Rhabdastrella, Stelletta and Vulcanella). Conclusion The Astrophorida is a larger order than previously considered, comprising ca. 820 species. Based on these results, we propose new classifications for the Astrophorida using both the classical rank-based nomenclature (i.e., Linnaean classification) and the phylogenetic nomenclature following the PhyloCode, independent of taxonomic rank. A key to the Astrophorida families, sub-families and genera incertae sedis is also included. Incongruences between our molecular tree and the current classification

  9. Development of a multilocus-based approach for sponge (phylum Porifera) identification: refinement and limitations.

    2017-02-02

    For sponges (phylum Porifera), there is no reliable molecular protocol available for species identification. To address this gap, we developed a multilocus-based Sponge Identification Protocol (SIP) validated by a sample of 37 sponge species belonging to 10 orders from South Australia. The universal barcode COI mtDNA, 28S rRNA gene (D3-D5), and the nuclear ITS1-5.8S-ITS2 region were evaluated for their suitability and capacity for sponge identification. The highest Bit Score was applied to infer the identity. The reliability of SIP was validated by phylogenetic analysis. The 28S rRNA gene and COI mtDNA performed better than the ITS region in classifying sponges at various taxonomic levels. A major limitation is that the databases are not well populated and possess low diversity, making it difficult to conduct the molecular identification protocol. The identification is also impacted by the accuracy of the morphological classification of the sponges whose sequences have been submitted to the database. Re-examination of the morphological identification further demonstrated and improved the reliability of sponge identification by SIP. Integrated with morphological identification, the multilocus-based SIP offers an improved protocol for more reliable and effective sponge identification, by coupling the accuracy of different DNA markers.

For this synopsis, diversity and distribution of SE Asian inland water sponges is reported on the basis of available literature and a recent biodiversity assessment of the Lower Mekong basin. A diagnostic key of families/genera from SE Asia is provided together with Light Microscopy and Scanning Electron Microscopy protocols to prepare the basic spicular complement for taxonomic identification. So far, SE Asian freshwater sponges consist of widespread and/or endemic species belonging to the families Metaniidae, Potamolepidae, and Spongillidae. The highest diversity is recorded from Indonesia, Philippines, Thailand, and Myanmar, respectively. Data from the other countries are necessary for our understanding of their diversity and distribution. Biodiversity in SE Asia is strongly underestimated, as indicated by recent new records and the discovery of new species of freshwater sponges in Thailand. Further investigations should reveal higher values of taxonomic richness, highlighting biogeographic patterns at the family/genus/species levels. A cooperative network involving Thai, Laotian and Italian researchers, was set up to contribute and fulfil knowledge on taxonomy, ecology and biotechnological potentialities of these neglected filter feeders, playing a key role in water purification and biomass production in both lentic and lotic ecosystems in the tropics.

    Over the past several decades molecular tools have shown an enormous potential to aid in the clarification of species boundaries in the marine realm, particularly in morphologically simple groups. In this paper we report a case of cryptic speciation in an allegedly cosmopolitan and ecologically important species-the excavating sponge Cliona celata (Clionaidae, Hadromerida). In the Northeast Atlantic and Mediterranean C. celata displays a discontinuous distribution of its putative growth stages (boring, encrusting, and massive) leading us to investigate its specific status. Phylogenetic reconstructions of mitochondrial (COI, Atp8) and nuclear (28S) gene fragments revealed levels of genetic diversity and divergence compatible with interspecific relationships. We therefore demonstrate C. celata as constituting a species complex comprised of at least four morphologically indistinct species, each showing a far more restricted distribution: two species on the Atlantic European coasts and two on the Mediterranean and adjacent Atlantic coasts (Macaronesian islands). Our results provide further confirmation that the different morphotypes do indeed constitute either growth stages or ecologically adapted phenotypes as boring and massive forms were found in two of the four uncovered species. We additionally provide an overview of the cases of cryptic speciation which have been reported to date within the Porifera, and highlight how taxonomic crypsis may confound scientific interpretation and hamper biotechnological advancement. Our work together with previous studies suggests that overconservative systematic traditions but also morphological stasis have led to genetic complexity going undetected and that a DNA-assisted taxonomy may play a key role in uncovering the hidden diversity in this taxonomic group.

  14. Molecular phylogenetic evaluation of classification and scenarios of character evolution in calcareous sponges (Porifera, Class Calcarea.

    Directory of Open Access Journals (Sweden)

    Oliver Voigt

    Full Text Available Calcareous sponges (Phylum Porifera, Class Calcarea are known to be taxonomically difficult. Previous molecular studies have revealed many discrepancies between classically recognized taxa and the observed relationships at the order, family and genus levels; these inconsistencies question underlying hypotheses regarding the evolution of certain morphological characters. Therefore, we extended the available taxa and character set by sequencing the complete small subunit (SSU rDNA and the almost complete large subunit (LSU rDNA of additional key species and complemented this dataset by substantially increasing the length of available LSU sequences. Phylogenetic analyses provided new hypotheses about the relationships of Calcarea and about the evolution of certain morphological characters. We tested our phylogeny against competing phylogenetic hypotheses presented by previous classification systems. Our data reject the current order-level classification by again finding non-monophyletic Leucosolenida, Clathrinida and Murrayonida. In the subclass Calcinea, we recovered a clade that includes all species with a cortex, which is largely consistent with the previously proposed order Leucettida. Other orders that had been rejected in the current system were not found, but could not be rejected in our tests either. We found several additional families and genera polyphyletic: the families Leucascidae and Leucaltidae and the genus Leucetta in Calcinea, and in Calcaronea the family Amphoriscidae and the genus Ute. Our phylogeny also provided support for the vaguely suspected close relationship of several members of Grantiidae with giantortical diactines to members of Heteropiidae. Similarly, our analyses revealed several unexpected affinities, such as a sister group relationship between Leucettusa (Leucaltidae and Leucettidae and between Leucascandra (Jenkinidae and Sycon carteri (Sycettidae. According to our results, the taxonomy of Calcarea is in

    Although there is a long history of taxonomic investigation in Caribbean sponges, there are still many undescribed species. Furthermore, field observations and corroborating morphological analyses are revealing that what was believed to be single, somewhat variable species, may consist of two or more species, often easier to distinguish once well characterized. This is the case for Dragmacidon reticulatum (Ridley & Dendy, 1886) (Porifera, Demospongiae, Axinellida, Axinellidae), a rather well-known sponge, with an ample distribution and presence in rocky and reef environments of the tropical and subtropical Western Atlantic, with local records in the majority of the countries of the area, from Bermuda to Brazil. Field observations and a detailed review of material from different areas, including some type specimens, led us to the distinction of two different species in terms of external morphology, size of spicules, and skeletal architecture. The distinction was confirmed in the Bahamas and Santa Marta, Colombia, where the two species coexist. One of the species is Dragmacidon reticulatum sensu stricto, but for the other there is need to erect a new name, for which we propose Dragmacidon alvarezae n. sp. The purpose of the present work is to describe, illustrate and compare these two species.

    2006-01-01

    The mesothelioma is a neoplasia originated in the serous membranes that drape the cellomic cavities and there cover the visceras that they contain, whose development has related to the exhibition to the asbestos. The present study describes the characteristics of the cases of mesothelioma pleural diagnosed in 3 adults hospitals in Costa Rica. 29 cases of pleural mesothelioma were found between 1972 and 2002 after reviewing the pathology service archives of the 3 national general hospitals of the Costa Rican social security health system. The incidence rate in 2002 was 1 case per 2 million; there were 15 females and 14 males, with a mean age of 54 years. Twenty cases presented with pleural effusion being dyspnea, chest pain, cough, fever and weight loss the most frequent symptoms. The disease was detected in all the cases because of an abnormal chest X-ray. The method used to obtain tissue for histological diagnosis was thoracotomy for 15 cases, pleural biopsy in 8, thoracoscopy in 4 and autopsy in 2. The histological diagnosis in 16 cases was fibrous mesothelioma, 10 malignant and 6 benign, 11 were epithelial (all malignant) and 2 were malignant mixed mesothelioma. The treatment in all the benign cases was surgical resection and none recurred. Two of the malignant lesions were resected, 1 had an extrapleural pneumonectomy along with pericardial and diaphragmatic resection, but the survival was not better than the rest of the malignant cases, with an average survival rate for all of them of only 6 months. Chemotherapy and radiotherapy showed no additional benefit. (author) [es

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. The cables run in corrugated metal tubes, and these were kept in precise position with the aid of distance pieces.El nuevo edificio, destinado a agrupar los servicios del Banco Central de Costa Rica, está constituido por una estructura de hormigón pretensado. El inmueble dispone de un sótano, estacionamiento propio para 105 vehículos y nueve plantas, con una superficie total de 12.000 metros cuadrados. Se asienta sobre una base de 40x60 m, donde se levanta un núcleo central de 22x45 metros. Está situado en un barrio de calles estrechas, pero tiene su fachada, principal frente a una zona verde que le proporcionará mayor categoría y visibilidad.

    The management system of electronic waste is a project organized and financed by the bilateral agreement Costa Rica - Holanda, it is integrated by governmental and non-governmental enterprises. It was divided in two phases, first performed in 2003 which provided a diagnosis on the management of electronic resources, based on the diagnosis a propose of strategy for recycling was made. The second phase is given in 2005 with the implementation and realization of the project including two pilots plans located one at the Instituto Tecnologico de Costa Rica and another in the community of Escazu, at the end some recommendations were given to strengthen the system. The electronic waste were divided in white line, gray and brown line; those with pollutants such as phosphorus, chromium, cadmium, barium, lead, beryllium, mercury are toxic and have different effects on human health. The project in Costa Rica has taken as examples several recycling plants in different countries, among them one installed in Belgica. As an outstanding figure of the diagnosis made it was determined that Costa Rica has no legal support regarding the handling of such materials. It has been accumulated in 2007 more than 24 260 tonnes and is growing rapidly year after year. Within the achieved progress in the implementation of the project are: the creation of a legal support, the organization of the compliance unit of the project, the valuation of environmental costs and the increase of enterprises offering the service of primary treatment [es

    Full Text Available Este estudo tem como objetivo pesquisar a existência de um legado grego terminológico na organização gramatical brasileira, considerando que a gramática incipiente grega é a fonte da nossa gramática, por via da gramática latina, e que o recorte de campo que ela preparou é um ponto de referência para o estudo da evolução do pensamento ocidental sobre a linguagem. A orientação teórico-metodológica se assenta na Linguística Histórica, na linha que orientou a ampla pesquisa sobre a emergência da gramática no Ocidente que constitui a fonte das informações que aqui se organizam (NEVES, 2005. As reflexões dirigem-se especialmente para o exame da nomenclatura, entendendo que ela mapeia conceptualmente o conjunto das posições assumidas, e em geral mantidas, que merecem apreciação. Entre outras coisas o exame opôs: termos gregos legados na corrente contínua do pensamento gramatical a termos gregos introduzidos posteriormente; termos transliterados do grego a termos decalcados da tradução latina. Além disso, verificaram-se casos de alteração de nome com manutenção de conceito, e casos de alteração de conceito para um nome conservado. De todo modo, o exame da nomenclatura revela a indiscutível existência de um legado grego à organização da gramática portuguesa.

Observou-se que tão importante quanto contribuir para a geração e formação do PIB, de emprego, impostos, salários e balança comercial é o poder que um setor produtivo tem a mais que o outro de multiplicar estes indicadores quando uma unidade monetária é gasta a mais pelos consumidores finais na demanda por produtos deste determinado setor. Os resultados indicaram que o setor florestal é um dos setores da economia brasileira que apresentou os maiores efeitos multiplicadores para os indicadores socioeconômicos, sendo superiores aos de outros como o da indústria automobilística, de equipamentos elétricos e eletrônicos, de máquinas e equipamentos e de produtos químicos e petróleo.

La diversificación agrícola que promovió Costa Rica en la década de los ochenta, permitió ampliar la oferta exportable y reducir la vulnerabilidad de la dependencia económica de productos tradicionales, como café y banano. Los retos de la economía global y el establecimiento de tratados comerciales con muchos países, hacen necesario que el país promueva en el sector agrícola la exportación con mayor valor agregado, para lo cual es necesario una modernización y reconversión productiva, ya que el modelo actual está agotado. Debemos mejorar sustancialmente los bienes y servicios que ofrecemos; para este propósito, algunos aspectos como la imagen de marca del país con tradición democrática, respeto a los derechos laborales, así como las buenas prácticas de manejo ambiental, deben publicitarse. Como una herramienta clave para la incorporación de mayor valor agregado a nuestra producción agrícola, debemos promover la inversión en investigación y desarrollo, que históricamente ha sido escasa (0,4% del PIB. En vista de que el Estado Costarricense ha demostrado una incapacidad crónica para impulsar la ciencia y la tecnología como una herramienta para nuestro desarrollo, se propone un estímulo a la inversión privada y el fortalecimiento de una alianza con el Estado y las universidades. Se analiza la conveniencia del fortalecimiento de la autosuficiencia alimentaria y de que las empresas pequeñas y medianas jueguen un papel más activo en la agro-exportación. Respecto a los tratados comerciales que se han venido negociando, se considera la conveniencia para el país, ya que son instrumentos para integrar nuestro quehacer económico a nivel mundial, y nuestro deber es el de luchar para que el sector agropecuario tenga oportunidad de subsistir competitivamente según esas nuevas reglas y

The calculation and mapping of contours of the global solar radiation in the country are focused. Experimental values and predicted global solar radiation has been used in the contouring. The highest values were observed in the northern section of the Pacific slope and west of the Valle Central; the north and along the Caribbean coast have the lowest values. Quantitative data are not limited to the direct use of solar energy for power generation, also for other activities such as meteorological sciences, agriculture, irrigation and forest architecture. This information is important for specialists, teachers and professionals interested in harnessing solar energy. (author) [es

    Costa Rica, a small country with the population of 4 million, and without military and hence no military expenditure, promotes the use of renewable sources like Hydro, Mini hydro, Wind, Geothermal and Sun, mainly for electricity generation. Almost 90% of the electricity is produced from these renewable sources. Through different policies and some incentives, etc., private generation is also encouraged and there are some decentralized systems like solar water heaters, swimming pool heaters, cookers, dryers and stills and also photo voltaic panels. The last ones are mostly for the population where there is no electric grid. Depending on the province, 91-99.5% of the population is electrified. Government also encourages the use of energy saving devices specially at domestic and industrial sector. In addition to provide these data, some of the solar energy systems are mentioned. [Author].

    1992-07-01

    This report presents an analysis of the different public and private institutions, that in any form applies ionizing radiations. In total a sample of 387 was considered; it offers a great reliability, considering the size of Costa Rican market. Fundamentally the information was taken from the archives of the Atomic Energy Commision of Costa Rica; also from reports of labors and surveys carried out during 1991, tending to justify the Project ARCAL XVI: Industrial Applications of the Nuclear Technology.

    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 O presente trabalho trata das exportações brasileiras de madeira serrada de não coníferas, laminados e compensados durante o período de 1961 a 2002. Os dados referentes aos três produtos estudados foram agregados pelo método de Fisher para que pudesse ser feita uma avaliação econométrica do mercado dos três produtos. Foram especificados modelos de oferta e demanda das exportações brasileiras e estas estimados pelo método de Mínimos Quadrados Ordinários (MQO. Os resultados foram satisfatórios e condizem com a literatura. A oferta de exportações apresentou uma resposta positiva em relação à remuneração do exportador, à produção, à utilização da capacidade instalada e à tendência, e negativo em relação à demanda interna. A demanda pelas exportações brasileiras foi positivamente influenciada pela renda mundial, índice de participação e tendência, e negativamente pelo preço relativo. A baixa elasticidade-preço da demanda encontrada pode ter implicações na conservação dos recursos florestais brasileiros, pois os exportadores poderão aumentar os preços, diminuir as quantidades e ainda terem um aumento das receitas.

    Full Text Available Glaucoma is the second most frequent cause of irreversible blindness worldwide. Genetic factors have been implicated in the development of the disease. So far six loci (GLC1A-GLC1F and two genes (TIGR/MYOC and OPTN are involved in the development of juvenile (JOAG and adult onset or chronic primary open angle glaucoma (COAG, while two loci (GLC3A,GLC3B and one gene (CYP1B1 are known for primary congenital glaucoma (PCG. Here we summarize the results of the first genetic studies of glaucoma in Costa Rica. Nine families: 1 with JOAG, 1 with PCG and 7 with COAG were screened for mutations at the known genes. A10 bp duplication, 1546-1555dupTCATGCCACC, at the CYP1B1 gene, causes, in homozygous state, glaucoma in the consanguineous PCG family. This mutation has been found in different countries and generates an early stop codon that termitates protein synthesis 140 amino acids earlier than the normal allele. In exon 1 of the TIGR/MYOC the innocuous Arg76Lys variant was found in two of the COAG families. In the OPTN gene two variants in the coding region (Thr34Thr, Met 98Lys and 7 intronic changes were found in other Costa Rican glaucoma patients. One of the COAG families was chosen for a genome scan with 379 microsatellite markers and linkage analysis. LOD scores "suggestive" of linkage were obtained for several chromosomal regions. Evidence indicates that hereditary glaucoma in Costa Rica is highly heterogeneous and that further studies in the country will probably disclose some up to now unknown genes responsible for the disease. Rev. Biol. Trop. 52(3: 507-520. Epub 2004 Dic 15.El glaucoma es la segunda causa de ceguera irreversible en el mundo.

    Full Text Available Este trabalho sugere a classificação de seis tipos de costão marinho, sete tipos de falésia, bancada e três formas de campo de blocos costeiro, de acordo com as características da geomorfologia costeira brasileira. Aponta ainda para os problemas que podem ocorrer com a ocupação e uso das faixas de lavagem das ondas, que constituem áreas de risco. A maior parte do litoral do Estado do Rio de Janeiro é formada por costões, cuja inclinação é classificada neste trabalho entre 15° e 45°. Acima deste limite é considerado falésia. Existem ainda extensos depósitos de blocos produzindo situações antagônicas: muitos foram originados por eventos catastróficos, mas posteriormente passaram a promover certa proteção à costa, por formar barreiras que dissipam a energia das ondas. Em geral, os costões marinhos nas áreas expostas às ondas de tempestades possuem inclinação média de 30° e comprimento médio de 50m. A extensão aumenta à medida que a inclinação da encosta diminui porque as ondas alcançam áreas mais distantes. Nas áreas semi expostas e protegidas, os comprimentos diminuem. No Estado foram identificadas 13 regiões costeiras distintas, entretanto, da divisa Oeste até a Ilha da Marambaia são comuns depósitos de blocos; nos municípios do Rio de Janeiro e Niterói predominam costões marinhos; entre Arraial do Cabo e Búzios, prevalecem falésias cristalinas; e entre Rio das Ostras e Macaé, o perfil do tipo bancada é o mais comum.

  2. Perspective View with Landsat Overlay, Costa Rica

    Science.gov (United States)

    2002-01-01

    This perspective view shows the Caribbean coastal plain of Costa Rica, with the Cordillera Central rising in the background and the Pacific Ocean in the distance. The prominent river in the center of the image is the Rio Sucio, which merges with the Rio Sarapiqui at the bottom of the image and eventually joins with Rio San Juan on the Nicaragua border.Like much of Central America, Costa Rica is generally cloud covered so very little satellite imagery is available. The ability of the Shuttle Radar Topography Mission (SRTM) instrument to penetrate clouds and make three-dimensional measurements will allow generation of the first complete high-resolution topographic map of the entire region. These data were used to generate the image.This three-dimensional perspective view was generated using elevation data from SRTM and an enhanced false-color Landsat 7 satellite image. Colors are from Landsat bands 5, 4, and 2 as red, green and blue, respectively. Topographic expression is exaggerated two times.Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter resolution of most Landsat images and will substantially help in analyses of the large and growing Landsat image archive. The Landsat 7 Thematic Mapper image used here was provided to the SRTM by the United States Geological Survey, Earth Resources Observation Systems (EROS) Data Center, Sioux Falls, S.D.Elevation data used in this image was acquired by the SRTM aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices

    Full Text Available Na última década, muita coisa mudou no Brasil, também no âmbito das religiões. O censo de 2000 nos diz que o País está hoje menos católico, mais evangélico e menos afro-brasileiro. Velhas tendências foram confirmadas, novas direções vão se impondo. Religiões recém-criadas se enfrentam com as mais antigas, velhas religiões assumem novas formas e veiculam renovados conteúdos para enfrentar a concorrência mais acirrada no mercado religioso. Vou tratar aqui de um ramo religioso pequeno demograficamente, porém importante do ponto de vista de seu significado para a cultura brasileira e da visibilidade que transborda de seu universo de seguidores: as religiões afrobrasileiras. Trata-se de acompanhar as mudanças numéricas encontradas pelos censos para dimensionar os seguidores das religiões afro-brasileiras, e de examinar algumas de suas características, como cor e scolaridade, para então avançar, sem perder de vista as peculiaridades constitutivas e organizacionais dos cultos e terreiros, alguma explicação sobre mudanças pelas quais vêm passando essas religiões nos dias de hoje

O foco nos poríferos foi motivado pela grande biomassa de esponjas no fenômeno de arribação da baía e ausência de pesquisas sobre esses animais na área do ensino. A metodologia esteve pautada nas representações sociais, pois conhecimentos (reconstruídos na vivência de um local característico, como o apresentado por esse ambiente, permitem desenhar perspectivas que subsidiam o ensino de Ciências, por exemplo, no tratamento dos obstáculos epistemológicos à aprendizagem de conceitos científicos.

    2005-01-01

    An evaluation of national mammographic equipment was conducted, due to the increasing incidence of breast cancer in Costa Rican women. From June 2002 to October 2003, 2 of the 3 global indicators of image quality were evaluated, (mean glandular dose and phantom image) in 26 mammography machines facilitated by radiologists in charge of the same. The mean glandular dose found was 1.75 ± 0.60 mGy with a range of 0.8 a 2.56. Regarding quality image, 73% of the evaluated equipment was able to see 4 or more fibers, 53% saw 3 or more groups of microcalcifications and 82% saw 3 or more mass groups. All mean glandular doses were below the international reference dose value of 3 mGy. However, the analysis of phantom images showed that only 54% of all the equipment had a total score (sum of mass groups, fibers and microcalcifications) superior or equal to 10, as expected. A correct diagnosis that could eventually save the patient's life is the main objective of a mammogram; the factors that are degrading the images must be found and it might be necessary to increase the doses to achieve this. This study demonstrates the urgent necessity to introduce permanent quality control programs that will provide excellent images with the lowest internationally recommended doses.(author) [es

    1980-01-01

    In an effort to identify the causal mechanisms involved in the relationship between education and fertility in Costa Rica, all married women who were interviewed in the National Fertility Survey were reinterviewed in 1977-78. Questions on modernity and attitudes toward family size were designed to measure the extent of their influence on fertility. Questions on modernity were grouped into 4 measures of mass communications/information, sex roles, husband's power, and "instrumental activism." The intercorrelation of the 4 measures was enough to justify their use as separate subscales but high enough to permit their combined use as a single measure of modernity. The correlation between the combined total and education was strong and positive at .68, while the correlation between education and the number of live births controlled for age was -.35. Results of a multiple regression analysis indicate that high levels of general information and exposure to mass media are responsible for the positive correlation between education and fertility. A variety of scales were developed to measure the extent to which predispositions toward family size, numerical preference, and desire for additional children were responsible for the relationship between general information and fertility. Modernity and education showed strong negative relationships to predisposition toward family size, moderate negative relationships to size preference, and almost no relationship to the desire for more children.

    Exhumed faults are rough, often exhibiting topographic corrugations oriented in the direction of slip; such features are fundamental to mechanical processes that drive earthquakes and fault evolution. However, our understanding of corrugation genesis remains limited due to a lack of in situ observations at depth, especially at subducting plate boundaries. Here we present three-dimensional seismic reflection data of the Costa Rica subduction zone that image a shallow megathrust fault characterized by corrugated, and chaotic and weakly corrugated topographies. The corrugated surfaces extend from near the trench to several kilometres down-dip, exhibit high reflection amplitudes (consistent with high fluid content/pressure) and trend 11–18° oblique to subduction, suggesting 15 to 25 mm yr−1 of trench-parallel slip partitioning across the plate boundary. The corrugations form along portions of the megathrust with greater cumulative slip and may act as fluid conduits. In contrast, weakly corrugated areas occur adjacent to active plate bending faults where the megathrust has migrated up-section, forming a nascent fault surface. The variations in megathrust roughness imaged here suggest that abandonment and then reestablishment of the megathrust up-section transiently increases fault roughness. Analogous corrugations may exist along significant portions of subduction megathrusts globally.

    Full Text Available Costa Rica followed different steps in order to organise and implement a waste of electrical and electronic equipment (WEEE management system. This paper summarises the challenges, successes, and limitations of its implementation. Two phases were needed to set up the system. The first phase created a baseline followed by the designing of a strategy. The second phase promoted a Decree for WEEE management that prohibits discarding WEEE together with household waste, as well as the creation of a National Executive Committee with representatives of importers, consumers, and government, which will establish the quotes and treatment fees, and so on. Another outcome was the development of a strategy for the implementation of WEEE management for the country, the promotion of population awareness about their responsibility for WEEE management, and an example set up for other Latin American countries. This paper draws conclusions from the regulation and notes the required consistency with the existing national waste legislation in order to reduce approval times. Additionally, the importance of the participation of stakeholders representing different electric and electronic equipment (EEE sectors with the purpose of obtaining consensus on agreements is highlighted.

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

    Ultraviolet radiation (UV) has contributed relatively little energy to the solar spectrum; but is important, because it is biologically active. The software Surfer 8 has created maps designed of the territory of Costa Rica to assess the maximum levels of solar UV radiation on a horizontal plane. The data were used in creating the maps, were predicted at local noon in eighty-three locations scattered across the country, with a spectral atmospheric model which is physically established. The model has used as input data: the date and time, the location identified by latitude, longitude and height of land above sea level, the value of the vertical column ozone, surface albedo and atmospheric turbidity parameters. The estimate differs by 3% of the measurements made in situ, which agrees with the experimental data. The model has used the data estimation of UV radiation, clear sky conditions, which is the condition where you get the maximum energy possible in each locality. This is of fundamental importance when assessing the adverse effects on human health, leads the maximum intensity in this important solar spectrum band. A larger increase of 23% has presented in the UV radiation with altitude obtaining the hills and mountains the highest rates and places located at sea level and the lowest cost, the indices. The annual variation analysis has revealed an increase greater than 27% from the month of lowest UV radiation (December) and the month of greatest UV radiation (April). The issue is of particular interest because of the increasing number of people moving at different times of the year, altitudes over 2000 m altitude, in activities relating to tourism and employment. These individuals are significant increases in levels of UV solar radiation under conditions of clear skies. (author) [es

    artículo -- Universidad de Costa Rica, Programa de Investigación en Desarrollo Urbano Sostenible. 2010 Agrotourism is a form of tourism that encourages visitors to experience rural culture as a tourist attraction. The term “agro-ecotourism” was used for the first time in Costa Rica in 1994, and it is generally used as synonym of agrotourism. Nonetheless, not all cases of agrotourism display sufficient concern for the environment to be considered agro-ecotourism. The aim of the ...

    Throughout his long productive scientific career, Erminio Costa demonstrated several scholarly traits that illustrate a pattern for paths of successful achievement that should guide young scientists. Not only did he seek excellent training, he got and gave good mentoring. That guidance allowed him to ask important questions and to develop the methods necessary to obtain definitive answers by pursuing those questions in depth. Without question, he blazed trails in neuropharmacology that have been an inspiration to many others and me. This article is part of a Special Issue entitled 'Trends in neuropharmacology: in memory of Erminio Costa'.

    Full Text Available Este trabalho tem por objetivo analisar o papel dos choques de produtividade para a agricultura brasileira. Os choques de produtividade foram subdivididos em dois tipos, choques de produtividade advindos de avanços tecnológicos e choques não tecnológicos, devidos a variações climáticas. O referencial teórico tem como base um modelo de Small Open Economy fundamentado na teoria RBC. Na estimação do modelo fez-se uso de econometria bayesiana. Os resultados demonstram que um maior grau de endividamento do setor agrícola geraria um estoque de capital superior, o que poderia ter potencializado os choques de produtividade e melhorado o desempenho econômico da agricultura.

    2016-12-01

    Full Text Available Este artigo tem o objetivo de propor a materialidade do corpo queer como um produto estilizado pela telenovela brasileira, justamente, por este corpo pertencer a um processo de montagem que prioriza na imagem a evidência de certa ausência. Dessa forma, a representação do corpo queer é um elemento visual de uma montagem ideológica coerente. Portanto, é preciso analisar as estruturas textuais televisivas, os aportes teóricos queer e as próprias definições de montagem e ausência. A partir do conceito de “Imagem-Mentira” de Didi-Huberman, nomes como John Fiske, John Hartley, Judith Butler, Michel Foucault e Jacques Rancière servirão de base teórica para a discussão.

It has approximately 3.5% of the world marine species. In the last four decades, Costa Rica has done a considerable effort to create a representative system of Protected Areas (PA, mainly terrestrial. We present an assessment of the current situation of the Marine Protected Areas (MPA in Costa Rica, through an historical analysis, and an evaluation of their distribution, coverage and management categories. Costa Rica has 166 protected areas covering 50% of the coastline; of these 20 are MPAs, classified as National Parks (90.6%, National Wildlife Refuges (6.6%, Wetlands (1.5%, Biological Reserves (1%, and one Absolute Natural Reserve (0.3%. According to IUCN criteria, 93.7% correspond to category II, 5% to IV and 1.3% to I. The marine protected surface is 5 296.5km², corresponding to 17.5% of the territorial waters and 0.9% of the Exclusive Economic Zone. The median distance between MPAs is 22.4km in the Pacific and 32.9km along the Caribbean. The median size is close to 54km². The main threats to MPAs are the lack of coordination between governmental agencies, limited economic resources, restricted patrolling and control, poor watershed management, and rampant coastal alteration.

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.

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.

    Full Text Available The rational use of water is essentual as it is a finite resource. Consequerntly, studies of methids that minimize water use water are essential. As a result, agricultural hydrogels have been extensively tested in as a means of promoting agriculture improvements because of their water- and nutriente-retention characteristics. However, even though hydrogels are used in several sectors of Brazilian agriculture, there are still very few studies on their applications, the best methods and the quantities to be used. Consequently, there is a need for research into the applicability of this technology in Brazil, so that future research needs can be identified and appropriate decisions made at the production level. Therefore, the aim of this study was to collate currently available information on the applicability of agricultural hydrogels in Brazilian agriculture. Over the last decade, forestry is the sector in Brazil that has most studied and used hydrogels, but others such as fruit- and coffeegrowing have also been involved. The method of applying the polymer in granules directly mixed-in with growth substrates is the most used in the production of seedlings. However, use of hydrated gel at planting sites has also been explored. While synthetic hydrogels are most commonly used, those made of natural materials have great potential due to the low preparation costs and their in-soil biodegradability. The quantities of hydrogel used vary according to the target species, application method and objective. = A utilização racional da água faz-se necessária uma vez que esse recurso é finito, assim, estudos sobre a produção e minimização do uso da água são essenciais.

The marine protected surface is 5 296.5km², corresponding to 17.5% of the territorial waters and 0.9% of the Exclusive Economic Zone. The median distance between MPAs is 22.4km in the Pacific and 32.9km along the Caribbean. The median size is close to 54km². The main threats to MPAs are the lack of coordination between governmental agencies, limited economic resources, restricted patrolling and control, poor watershed management, and rampant coastal alteration.Con 51 100km2 de área terrestre y 589 000km² de aguas jurisdiccionales, Costa Rica es considerado uno de los países con mayor biodiversidad. Posee aproximadamente 3.5% de las especies marinas del mundo. En las últimas cuatro décadas, Costa Rica ha dedicado un esfuerzo significativo para la creación de Áreas Protegidas (AP, principalmente terrestres.

    Full Text Available Este artigo apresenta os resultados de uma pesquisa realizada em três publicações jornalísticas brasileiras de caráter cultural, a saber: Cult, Bravo e Brasileiros, que foram analisadas com o objetivo de identificar a visibilidade das manifestações culturais em suas páginas, por meio do mapeamento das matérias veiculadas. Em outro prisma, o intuito foi mapear os gêneros jornalísticos mais trabalhados na veiculação das matérias referentes à cultura, com vistas a identificar o grau de importância dado ao temas culturais retratados nas publicações, assim como, verificar as tendências no texto do Jornalismo Cultural. A metodologia utilizada no primeiro caso foi o diagnóstico simples e no segundo caso foi análise de conteúdo por emparelhamento. Ao final conclui-se que embora o Jornalismo Cultural brasileiro esteja se abrindo para divulgar a diversidade do país, ainda permanece uma predominância destacável dos eventos do sudeste entre os temas pautados pelas publicações citadas.

Por meio de um breve levantamento bibliográfico, foi possível observar que atualmente há uma grande quantidade de livros, dissertações e teses sobre a História da África e do negro no Brasil. Destaca-se que, nas últimas décadas, um movimento acadêmico sobre a temática da Baixada Fluminense gerou significativa produção historiográfica sobre a região. Entretanto, percebe-se que os avanços historiográficos repercutiram de forma limitada fora dos circuitos de especialistas e que isso tem impactado na produção de material didático e, consequentemente, na simplificação dos debates.

    Full Text Available Analisando-se a situação atual da geografia brasileira, observa-se que ela é uma das mais ativas que temos conhecimento, de vez que ela é ministrada em nível superior e em nível de pós-graduação em dezenas de universidades situadas nos mais diversos pontos do país. Os geógrafos contribuem com uma vasta produção científica, em livros, em revistas especializadas e não especificamente geográficas, realizam seminários, congressos e reuniões científicas várias vezes por ano e em pontos diversos do território nacional. Além disto, participam ativamente, contribuindo com trabalhos que são apresentados em congressos e simpósios internacionais e desenvolvem trabalhos de planejamento e consultoria em órgãos públicos e privados.

Partindo destes pressupostos, podemos refletir como a geografia, ciência que existe desde os tempos mais antigos, mas que se estruturou de forma académica a partir da segunda metade do século XIX, teve um desenvolvimento tão expressivo no país. Como, em um país com tradições universitárias relativamente recentes, pôde esta ciência despertar tão grande interesse, atingindo os limites que atingiu?

    An assessment of mineral potential, in terms of types and numbers of deposits, approximate location and associated tonnage and grades, is a valuable input to a nation's economic planning and mineral policy development. This study provides a methodology for applying benefit-cost analysis to mineral resource assessment programs, both to determine the cost effectiveness of resource assessments and to ascertain future benefits to the nation. In a case study of Costa Rica, the benefit-cost ratio of a resource assessment program was computed to be a minimum of 4:1 ($10.6 million to $2.5 million), not including the economic benefits accuring from the creation of 800 mining sector and 1,200 support services jobs. The benefit-cost ratio would be considerably higher if presently proposed revisions of mineral policy were implemented and benefits could be defined for Costa Rica

    Dengue virus (DENV) (Flavivirus, Flaviviridae) is a reemerging arthropod-borne virus with a worldwide circulation, transmitted mainly by Aedes aegypti and Aedes albopictus mosquitoes. Since the first detection of its main transmitting vector in 1992 and the invasion of DENV-1 in 1993, Costa Rica has faced dengue outbreaks yearly. In 2007 and 2013, Costa Rica experienced two of the largest outbreaks in terms of total and severe cases. To provide genetic information about the etiologic agents producing these outbreaks, we conducted phylogenetic analysis of viruses isolated from human samples. A total of 23 DENV-1 and DENV-2 sequences were characterized. These analyses signaled that DENV-1 genotype V and DENV-2 American/Asian genotype were circulating in those outbreaks. Our results suggest that the 2007 and 2013 outbreak viral strains of DENV-1 and DENV-2 originated from nearby countries and underwent in situ microevolution. © The American Society of Tropical Medicine and Hygiene.

    Full Text Available Understanding key aspects of the biology and ecology of chondrichthyan fishes (sharks, rays, and chimeras, as well as the range of threats affecting their populations is crucial given the rapid rate at which some species are declining. In the Eastern Tropical Pacific (ETP, the lack of knowledge, unreliable (or non-existent landing statistics, and limited enforcement of existing fisheries regulations has hindered management and conservation efforts for chondrichthyan species. This review evaluated our current understanding of Costa Rican chondrichthyans and their conservation status. Specifically, we (1 provide an updated checklist on the species richness, habitat use, and distribution patterns, (2 summarize the most relevant chondrichthyan studies (scientific publications, theses, and official technical reports, (3 identify knowledge gaps, (4 discuss fisheries-related threats, and (5 highlight the management challenges and research needs to effectively protect their populations. A total of 99 chondrichthyan species are formally recorded in Costa Rican waters, from which 15% are threatened with extinction and 41% are “Data Deficient” based on the IUCN (International Union for Conservation of Nature Red List. A total of 121 studies were published between 1891 and 2017; 82% in the Pacific (24% from Isla del Coco and only 18% from the Caribbean Sea. These results highlight the need to redirect research efforts on specific taxonomic groups and geographic regions (i.e., Caribbean. Based on our review, improving the quality and quantity of fisheries landing statistics, as well as determining the degree of overlap between chondrichthyans and Costa Rican fisheries remains a priority. We proposed an adaptive management framework for chondrichthyan fisheries in data-poor countries where management goals/targets are clearly defined. This framework could strengthen the conservation of chondrichthyan populations in Costa Rica and the region.

    Cost Rica's contraceptive social marketing project is scheduled to be launched in March 1985. The project is run through a for-profit corporation, Asdecosta, which is owned by the Costa Rican International Planned Parenthood affiliate. Asdecosta was formed as a for-profit entity because Costa Rican law prohibits product sales by nonprofit groups. The US Agency for International Development (AID) will allocate US$1.2 million over a 5-year period, 1983-88. The project manager, Jorge Lopez, is an economist with considerable experience in marketing. The project has lined up a top national distributor, a packaging company, and an advertising agency for its 1st product, a condom manufactured in the US by Ansell. Asdecost's target market is projected to include 50,000-75,000 couples at its peak operating capacity. An estimated 65% of Costa Rican women have used a contraceptive method at some time. The condom, pill, and IUD are the most popular methods. Eventually, Asdecosta expects to expand its product line to include oral contraceptives. Another goal is to counter the high drop out rate among users of government and other family planning services.

    Several highly infectious diseases can be transmitted through feces and cause elevated mortality among carnivore species. One such infectious agent, canine distemper virus (CDV; Paramyxoviridae: Morbillivirus), has been reported to affect wild carnivores, among them several felid species. We screened free-ranging and captive wild carnivores in Costa Rica for CDV. Between 2006 and 2012, we collected 306 fecal samples from 70 jaguars (Panther onca), 71 ocelots ( Leopardus pardalis ), five jaguarundis (Puma yaguaroundi), 105 pumas ( Puma concolor ), five margays ( Leopardus wiedii ), 23 coyotes ( Canis latrans ), and 27 undetermined Leopardus spp. We found CDV in six individuals: one captive jaguarundi (rescued in 2009), three free-ranging ocelots (samples collected in 2012), and two free-ranging pumas (samples collected in 2007). Phylogenetic analyses were performed using sequences of the phosphoprotein (P) gene. We provide evidence of CDV in wild carnivores in Costa Rica and sequence data from a Costa Rican CDV isolate, adding to the very few sequence data available for CDV isolates from wild Central American carnivores.

De todas as cidades brasileiras, São Paulo é a que menos merece o título de cidade. Falta-lhe um espaço cultural inovador, apesar da riqueza e dinâmica de sua economia e de sua força política. O conceito de cidade subjacente ao pensamento de Flusser orienta-se pelo modelo da pólis grega e da cidade de Praga, antes da Segunda Guerra. Além disso, Flusser valoriza os novos códigos (de linguagem, de expressão arquitetônica, estética, musical, pictoral, capazes de integrar as influências multiculturais da história brasileira. A autora procura compreender a argumentação de Flusser, hoje comparado a um Walter Benjamin da pós-modernidade, mostrando contudo que sua tese foi precipitada. Saiu nos anos 70 de São Paulo, antes do fim da ditadura; não conheceu as grandes realizações da Bienal de Arte Moderna; não conheceu o ciclo de realizações Arte e Cidade no fim da década de 90, essencialmente baseado nas tecnologias da micro eletrônica da era digital, do PC e da internet, que ela festejava como novas linguagens.This article discusses Vilém Flussers controversial thesis. The Czech philosopher lived in São Paulo for over 30 after having fled the Nazi occupation of Prague. Of all Brazilian towns, São Paulo is the one which least deserves to be called a city. It lacks an innovative cultural space, in spite of its rich and dynamic economy and political strength. The concept of city subjacent to Flussers view is based on the model of the Greek polis and on Prague before the Second World War. Flusser also values the new codes (of language, architectural, aesthetic, musical and pictorial expression which are parts of the multicultural influences on Brazilian history.

    The recent Voyager missions to Jupiter have highlighted the role of sulphur in volcanic processes on io. Although fumarolic sulphur and SO/sub 2/ gas are almost universal in terrestrial active volcanoes, and rare instances of sulphur lava flows have been reported, sulphur in a pyroclastic form has only been described from Poas Volcano, Costa Rica. Here we amplify the original descriptions by Bennett and Raccichini and describe a recent eruption of pyroclastic sulphur scoria and ejected blocks that are characterised by miniature sulphur stalactites and stalagmites.

    Full Text Available RESUMOEste artigo analisa o chamado tripé da política macroeconômica brasileira, que desde 1999 tem combinado um regime de metas de inflação, um regime de taxa de câmbio flutuante e metas de superávit fiscal primário. A menos que o seu modus operandi seja alterado, o tripé não será capaz de libertar a economia brasileira de outra "possível trindade": altas taxas de juros reais, a apreciação da taxa de câmbio real e crescimento econômico muito baixo. Depois de analisar brevemente a base teórica sob o tripé macroeconômico, o artigo mostra por que este regime de política macroeconômica, se avaliado numa perspectiva de longo ou médio prazo, não tem sido capaz de garantir a estabilidade dos preços nem o crescimento econômico. Além da sugestão de romper com a estratégia brasileira de crescer com poupança externa, o documento também sugere três principais formas de mudar o modus operandi do tripé brasileiro: i aumentar o horizonte de tempo para atingir a meta de inflação, como tem sido o experiência da maioria dos países que adotam esse regime de política monetária; ii restaurar o papel anticíclico da política fiscal brasileira; e iii adotar uma combinação de mecanismos que visem prevenir que a moeda brasileira entre em uma nova tendência cíclica da apreciação em termos reais.

    2010-05-01

    Costa Rica has coral communities and reefs on the Caribbean coast and on the Pacific along the coast and off-shore islands. The Southern section of the Caribbean coast has fringing and patch reefs, carbonate banks, and an incipient algal ridge. The Pacific coast has coral communities, reefs and isolated coral colonies. Coral reefs have been seriously impacted in the last 30 years, mainly by sediments (Caribbean coast and some Pacific reefs) and by El Niño warming events (both coasts). Monitoring is being carried out at three sites on each coast. Both coasts suffered significant reductions in live coral cover in the 1980's, but coral cover is now increasing in most sites. The government of Costa Rica is aware of the importance of coral reefs and marine environments in general, and in recent years decrees have been implemented (or are in the process of approval) to protect them, but limited resources endanger their proper management and conservation, including proper outreach to reef users and the general public.

    Studies of intraseasonal and annual cycles of meteorological variables, using projections of climate change, are nowadays extremely important to improve regional socio-economic planning for countries. This is particularly true in Costa Rica, as Central America has been identified as a climate change hot spot. Today many of the economic activities in the region, especially those related to agriculture, tourism and hydroelectric power generation are linked to the seasonal cycle of precipitation. Changes in rainfall (mm/day) and in the diurnal temperature range (°C) for the periods 1950-2005 and 2006-2100 were investigated using the NASA Earth Exchange Global Daily Downscaled Projections (NEX-GDDP) constructed using the CMIP5 (Coupled Model Intercomparison Project version 5) data. Differences between the multi-model ensembles of the two prospective scenarios (RCP 4.5 and RCP 8.5) and the retrospective baseline scenario were computed. This study highlights Costa Rica as an inflexion point of the climate change in the region and also suggests future drying conditions.

    The rapid population growth in Central America has created pressure on the largest tract of cloud forest spanning the Talamanca Mountains in Costa Rica and Panama. Of immediate concern is restoring hope in the forest and improving the standard of living among local people. Such is the goal of the Amistad Conservation and Development (AMISCONDE) project in the communities of Cerro Punta, Panama, and San Rafael in Costa Rica. Through agriculture, forestry, animal husbandry, environmental education, and community development, AMISCONDE aims to restore the degraded lands in the reserve's buffer zone and improve the income of the people. All the local people, the farmers, women and children have benefited from the project. Some of the activities carried out to meet its objectives include helping the farmers improve the productivity and marketability of their products by teaching them new technologies and giving agricultural credits to farmers, women, and youth groups. In addition, AMISCONDE conducts training courses to address the economic, social and educational needs of women and communities. It is assured that the community and the group will be prepared to continue on their own after the official AMISCONDE office is gone.

    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.

    Enamel lesions in development were identified and classified in patients of Llano Grande de Cartago, examined at the Facultad de Odontologia of the Universidad de Costa Rica. A guide is provided over the topic. 15 children and 2 Costa Rican adults were selected. Clinical examinations, radiographs and clinical photographs were used as data collection method. Dental defects of the enamel were classified according to the possible genetic causes and without genetic causes. Imperfect Amelogenesis (IA) was diagnosed in 10 of patients. Hypoplastic IA was determined in 3 siblings with autosomal recessive inheritance, for 16% of the total sample. Hypomineralized IA was identified in an adult and two of his sons, with autosomal dominant inheritance. The remaining 4 cases of IA have been sporadic. Lesions of dental fluorosis were determined in the Horowitz index in 4 individuals, from 2 unrelated families. Other defects unspecified of the enamel or hypoplasias were found in 3 individuals. Enamel lesions in development should be classified with precision, for the purpose to inform to patients affected about their condition, origin, prognosis and appropriate treatment. The basis are established to implement reliability in the construction of family genealogy, identification and classification of enamel lesions, as well as the probabilities of future generations to express the lesions in the enamel of temporary or permanent dentition [es

    The establishment of the first radioactivity levels of natural radiation was carried out during the period 1991 to 1994 in three different regions of Costa Rica. The radionuclides studied belong to different soil types related to each selected region. Utilizing low level counting techniques the specific activity of the natural radioactive chains 238 U daughters, 232 Th and the element 40 K were measured for a total of 120 samples during this period. The amount of 137 Cs, a fall out radionuclide, was also studied. The average national values in Bq.kg -1 measured for 238 U were 11.66 for 214 Bi, 34.42 for 226 Ra and 10.73 for 232 Pb, for 232 Th daughters were 4.08 for 208 Tl, 9.65 for 212 Bi and 7.62 for 228 Ac. The specific activity value for 40 K was 95.14 Bq.kg -1 and for 137 Cs was 2.38 Bq.kg -1 . It is found that Costa Rica is not highly natural radioactive country and that the values for 137 Cs are well below international reported values [es

It is important to identify those inequities, to establish policies and strategies trying to mitigate them. It applies the MIPSE classification proposed by members of the Information and Studies Service, of the Catalunya's Sanitary Resources Headquarter, Spain. By an Indicator of Socioeconomic Development (IDSE) of a University of Costa Rica economist's team, it organised each canton in groups of quintiles (I for the richest, V for the poorest), previous people standardization. We found as a major causes of mortality MIPSE in the country: Heart Isquemic Disease (19,55% MIPSE causes), Traffic Accidents with Motor Vehicles (11,60%), Brain Vascular Disease (6,95%), Perinatal (6,92%) and Suicide (5,14%). The VIH infection - AIDS mortality, the Best Cancer in Women, Uterus Cancer, Skin Cancer and Hepatic Disease Secondary to Alcohol Consumption, affects more the cantons with better financial conditions and the Prostate Benign Hyperplasia mortality, Mothers mortality related with Pregnancy, Childbirth or Puerperal Stage and the Abdominal Hernia mortality, affects more to those with worst economic level. Two MIPSE groups were identified with similar inequality: Leukaemia and Congenital Cardiovascular Disease.

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.

    Brucellosis has been an endemic disease of cattle and humans in Costa Rica since the beginning of XX century. However, brucellosis in sheep, goats, pigs, water buffaloes, horses and cetaceans, has not been reported in the country. We have performed a brucellosis survey in these host mammal species, from 1999-2016. In addition, we have documented the number of human brucellosis reported cases, from 2003-2016. The brucellosis seroprevalence in goat and sheep herds was 0.98% and 0.7% respectively, with no Brucella isolation. Antibodies against Brucella were not detected in feral or domestic pigs. Likewise, brucellosis seroprevalence in horse and water buffalo farms was estimated in 6.5% and 21.7%, respectively, with no Brucella isolation. Six cetacean species showed positive reactions against Brucella antigens, and B. ceti was isolated in 70% (n = 29) of striped dolphins (Stenella coeruleoalba). A steady increase in the diagnosis of human brucellosis cases was observed. Taking into account the prevalence of brucellosis in the various host mammals of Costa Rica, different measures are recommended.

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

    Full Text Available Market sales of ready-to-use fresh fruit and vegetables have grown quickly in the recent years as a result of changes in consumer attitudes. The goal of this work was to evaluate the effect of two kinds of cuts on the physiological, physical, physical-chemical, chemical and biochemical traits of fresh-cut 'Menina Brasileira' zucchini stored in rigid polypropylene packages, with lids of the same material containing sliced and grated zucchini and stored at 5º C, for 15 days. The variables respiratory rate, pH, L* value, soluble pectin, PME and PG activity, was interactively affected by the cut type and storage time factors. The variables mass loss, phenylalanine ammonia-lyase activity and total pectin variable were only significantly affected by storage time factor. It can be concluded that sliced 'Menina Brasileira' zucchini shows a higher titratable acidity and soluble solids and a lower respiratory rate, pectin soluble and phenylalanine ammonia-lyase activity when compared with grated zucchini, contributing to the preservation of quality attributes.As vendas no mercado de frutas e hortaliças frescas prontas para o consumo têm crescido rapidamente nos últimos anos como resultado de mudanças nas atitudes dos consumidores. Neste trabalho objetivou-se avaliar o efeito de dois tipos de cortes nas características fisiológicas, físicas, químicas, físico-químicas e bioquímicas de abobrinha 'Menina Brasileira' minimamente processada, armazenada a 5º C em embalagens de polipropileno rígido, com tampas do mesmo material, contendo abobrinha fatiada e ralada, por 15 dias. As variáveis taxas respiratórias, pH, valor L*, pectina solúvel, atividade de PME e PG, foram interativamente afetadas pelos fatores tipo de corte e tempo de armazenamento. As variáveis perda de massa, atividade da fenilalanina amônia-liase e a pectina total foram afetadas significativamente apenas pelo fator tempo de armazenamento. Pode-se concluir que a abobrinha

    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.

This was done following the methodology proposed by the Organization for Economic Cooperation and Development (OECD. The Monthly Economic Activity Index (IMAE in Spanish was selected as the reference variable.  A total of 270 data series were analyzed including monetary, real and job market variables, as well as price indices, external sector indicators and fiscal sector variables. The real sector information was disaggregated into three levels, which included the classification of data at an industrial level using the International Standard Industrial Classification (ISIC with two digits, information from the agricultural sector based on the Central Product Classification (CPC and information from the manufacturing sector.  A leading indicator was developed for each level of aggregation, resulting in average leads of 7 to 12 months compared to the reference variable.

    The organophosphorus and organochlorine agrochemical residues distribution in sediments of 3 rivers located in an ornamental plant production area were analyzed in Poas canton, Alajuela, Costa Rica. The study comprised 8 months in order to assure 3 seasonal episodes: dry, transitional, and rainy seasons. Sediments were taken in 10 sampling stations along the rivers and characterized by a determination of their organic matter and texture. In 7 out of 10 sampling stations pesticide residues were detected in at least 1 of 4 samplings, but quantified only in 4 stations. Agrochemical residues evaluated included 21 organophosphorus and organochlorine pesticides; however, we found residues of only 3 organochlorine pesticides, due their high persistence in the sediment. Residues corresponded to PCNB (80-800 μg.kg -1 ), Endosulfan-β (40-50 μg.kg -1 ), and Endosulfan-α (90 μg.kg -1 ). Chlorothalonil was detected in only one sample. (author) [es

    Full Text Available We assess the utility of mixed-frequency models to forecast the quarterly growth rate of Costa Rican real GDP: we estimate bridge and MiDaS models with several lag lengths using information of the IMAE and compute forecasts (horizons of 0-4 quarters which are compared between themselves, with those of ARIMA models and with those resulting from forecast combinations. Combining the most accurate forecasts is most useful when forecasting in real time, whereas MiDaS forecasts are the best-performing overall: as the forecasting horizon increases, their precisionis affected relatively little; their success rates in predicting the direction of changes in the growth rate are stable, and several forecastsremain unbiased. In particular, forecasts computed from simple MiDaS with 9 and 12 lags are unbiased at all horizons and information sets assessed, and show the highest number of significant differences in forecasting ability in comparison with all other models.

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.

    2005-01-01

    This note is a preliminary investigation into the relationship between the efficiency of electricity utilization in the Costa Rican industrial sector and the competitive pressures generated by the implementation of economic reforms, in particular, the progressive liberalization of international trade, in the years since the debt and economic crisis of the early 1980s. The steady, year-by-year, reduction in the rate of import tariff protection, with only temporary interruptions and reverses, has been the most consistently implemented component of the macroeconomic, trade, and financial sector reforms upon which this country has embarked over the past two decades. The note sheds some light on the nature of the general policy environment that is conductive to an efficient utilization of energy in the productive sectors and to the success of national energy efficiency promotion programs in this and other parts of the world.

    1995-01-01

    In San Jose, Costa Rica, the nongovernmental organization PROCAL has established two rescue homes for sexually abused girls 10-15 years of age. One of these homes is devoted to the care of pregnant girls. In almost all cases, the perpetrator was a male relative. Since girls are taught they must obey older male relatives, they are powerless to stop the abuse. When girls become pregnant as a result of sexual abuse, they face social ostracism and are blamed for their participation in sexual activity. PROCAL counsels the girls that they are victims of their own lack of power and provides them with skills and education they need to return to society and start a new life. The stories of two young girls who became pregnant as a result of sexual abuse and were helped by PROCAL are presented.

    2012-12-01

    Tropical mangroves provide a wide variety of ecosystem services, including atmospheric carbon sequestration. Because of their high rates of carbon accumulation, the large expected size of their total stocks (from 2 to 5 times greater than those of upland tropical forests), and the alarming rates at which they are being converted to other uses (releasing globally from 0.02 to 0.12 Pg C yr-1), mangroves are receiving increasing attention as additional tools to mitigate climate change. However, data on whole ecosystem-level carbon in tropical mangroves is limited. Here I present the first estimate of ecosystem level carbon stocks in mangrove forests of Central America. I established 28, 125 m-long, sampling transects along the 4 main rivers draining the Térraba-Sierpe National Wetland in the southern Pacific coast of Costa Rica. This area represents 39% of all remaining mangroves in the country (48300 ha). A circular nested plot was placed every 25 m along each transect. Carbon stocks of standing trees, regeneration, the herbaceous layer, litter, and downed wood were measured following internationally-developed methods compatible with IPCC "Good Practice Guidelines". In addition, total soil carbon stocks were determined down to 1 m depth. Together, these carbon estimates represent the ecosystem-carbon stocks of these forests. The average aboveground carbon stocks were 72.5 ± 3.2 MgC ha-1 (range: 9 - 241 MgC ha-1), consistent with results elsewhere in the world. Between 74 and 92% of the aboveground carbon is stored in trees ≥ 5cm dbh. I found a significant correlation between basal area of trees ≥ 5cm dbh and total aboveground carbon. Soil carbon stocks to 1 m depth ranged between 141 y 593 MgC ha-1. Ecosystem-level carbon stocks ranged from 391 MgC ha-1 to 438 MgC ha-1, with a slight increase from south to north locations. Soil carbon stocks represent an average 76% of total ecosystem carbon stocks, while trees represent only 20%. These Costa Rican mangroves

    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 The coral reefs, seagrasses and mangroves from the Costa Rican Caribbean coast have been monitored since 1999 using the CARICOMP protocol. Live coral cover at Meager Shoal reef bank (7 to 10m depth at the Parque Nacional Cahuita (National Park, increased from 13.3% in 1999, to 28.2% in 2003, but decreased during the next 5 years to around 17.5%. Algal cover increased significantly since 2003 from 36.6% to 61.3% in 2008. The density of Diadema antillarum oscillated between 2 and 7ind/m2, while Echinometra viridis decreased significantly from 20 to 0.6ind/m2. Compared to other CARICOMP sites, live coral cover, fish diversity and density, and sea urchin density were low, and algal cover was intermediate. The seagrass site, also in the Parque Nacional Cahuita, is dominated by Thalassia testudinum and showed an intermediate productivity (2.7±1.15 g/m2/d and biomass (822.8±391.84 g/m2 compared to other CARICOMP sites. Coral reefs and seagrasses at the Parque Nacional Cahuita continue to be impacted by high sediment loads from terrestrial origin. The mangrove forest at Gandoca, within the Refugio Nacional de Vida Silvestre Gandoca-Manzanillo (National Wildlife Refuge, surrounds a lagoon and it is dominated by the red mangrove, Rhizophora mangle. Productivity and flower production peak was in July. Biomass (14kg/m2 and density (9.0±0.58 trees/100m2 in Gandoca were relatively low compared to other CARICOMP sites, while productivity in July in Costa Rica (4g/m2/d was intermediate, similar to most CARICOMP sites. This mangrove is expanding and has low human impact thus far. Management actions should be taken to protect and preserve these important coastal ecosystems. Rev. Biol. Trop. 58 (Suppl. 3: 1-22.

    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.

Durante o processo de tradução para a língua portuguesa, algumas modificações foram realizadas no SCRQ. O instrumento traduzido foi aplicado durante entrevistas individuais - face a face - com 38 mulheres brasileiras. Os resultados da análise das respostas das mulheres mostraram que o SCRQ é confiável, culturalmente apropriado e adaptado, e assim pode ser empregado para medir padrões de respostas de auto cuidado entre mulheres brasileiras perimenopausais. Este estudo piloto demonstrou que a experiência da mulher em relação à menopausa e o conhecimento e interesse que ela tem sobre o assunto variam de pessoa para pessoa. Foram identificadas outras questões não abordadas pelo SCRQ que merecem ser investigadas, como por exemplo a quantidade e qualidade da atividade sexual durante todo o período menopausal.

    Full Text Available The genus Fluviphylax Whitley, 1965 is comprized of five valid species (F. pygmaeus Myers et Carvalho, 1955, F. zonatus, F. simplex, F. obscurus Costa, 1996, and F. palikur Costa et Le Bail, 1999, which are endemic to the Amazon region. These fishes are the smallest known South American vertebrates and among the smallest know vertebrates on Earth. All species but the type F. pygmaeus have been described in late 1990’s, and much remains unknown about the biology, taxonomy and systematics of this group of fishes. The aims of the present study were to establish the diploid and haploid number of F. zonatus and F. simplex, and to find species-specific markers for the discrimination of taxa. The diploid number for both species was 48 chromosomes, with no sex chromosome heteromorphism. Fluviphylax zonatus exhibited the karyotypic formula 4m+8sm+22st+14a and FN=82, and F. simplex exhibited 4m+16sm+18st+10a and FN=86. The determination of the total mean length of the chromosomes and their grouping into five size classes demonstrated different chromosome composition of the two species. This difference was further supported by the distribution of constitutive heterochromatin. The meiotic analysis revealed 24 bivalents in both species, but F. zonatus exhibited chromosomes with late pairing of the telomeric portions in the pachytene. These data reveal that cytogenetic characterization is useful and important for the discrimination of these species. Our study further indicates that this method could be employed in the analysis of other species of small fishes that are difficult to distinguish using traditional morphological traits or are morphologically cryptic.

    Full Text Available The coral reefs, seagrasses and mangroves from the Costa Rican Caribbean coast have been monitored since 1999 using the CARICOMP protocol. Live coral cover at Meager Shoal reef bank (7 to 10m depth at the Parque Nacional Cahuita (National Park, increased from 13.3% in 1999, to 28.2% in 2003, but decreased during the next 5 years to around 17.5%. Algal cover increased significantly since 2003 from 36.6% to 61.3% in 2008. The density of Diadema antillarum oscillated between 2 and 7ind/m2, while Echinometra viridis decreased significantly from 20 to 0.6ind/m2. Compared to other CARICOMP sites, live coral cover, fish diversity and density, and sea urchin density were low, and algal cover was intermediate. The seagrass site, also in the Parque Nacional Cahuita, is dominated by Thalassia testudinum and showed an intermediate productivity (2.7±1.15 g/m2/d and biomass (822.8±391.84 g/m2 compared to other CARICOMP sites. Coral reefs and seagrasses at the Parque Nacional Cahuita continue to be impacted by high sediment loads from terrestrial origin.

    Full Text Available Cancer is a worldwide problem because of its high rates of incidence and associated mortality. By 2000, more than 6.2 million people died from this illness worldwide. Among all types of cancer, breast cancer is one of the most studied. Each year, one million new cases are diagnosed around the world. We can classify breast cancer into two main kinds: sporadic cases and those which are a product of inherited genetic alterations. Approximately 5-10% of breast cancer cases are the result of inherited mutations, or alterations in breast cancer susceptibility genes, BRCA1 and BRCA2. Like other countries, Costa Rica possesses high rates of incidence and mortality for breast cancer. According to the "Registro Nacional de Tumores" (National Office of Tumor Records, in 2000 breast cancer had the highest rate of incidence and in 2002 it had the highest rate of mortality in comparison to other types of cancer. For this reason and the generalized lack of knowledge in the field we conducted an epidemiological research on breast cancer patients from Hospital San Juan de Dios, San José, Costa Rica, to find families with a history of breast cancer, and to determine the occurrence of familial cases within the population studied. So far, we have found 23 families, within which we discovered very informative cases that have rendered the identification of a pattern of inheritance. These findings allow us to announce that in Costa Rica there are several cases of inherited breast cancer and that we need more research is needed to improve the prevention, control, and treatment of this disease.

    2011-01-01

    Electron microscopy has celebrated in 2009 the XXXV anniversary in Costa Rica. The history of the electron microscopy was initiated with the donation of a microscope by Japan and the establishment of the Unidad de Microscopia Electronica (UME), which later, has been consolidated as the Centro de Investigacion en Estructuras Microscopicas (CIEMic) of the Universidad de Costa Rica (UCR). This center has realized its own research and has gave support to different units of the UCR, state universities and the private sector. Currently, the CIEMic has had two transmission electron microscopes (TEM) and two scanning electron microscopes (SEM), besides of optical microscopy equipment, including a laser confocal microscope. The two fundamental types of electron microscopes (TEM and SEM) have generated different images. While the first has had a resolution that has allowed to analyze virus, usually their images have been flat; however, with some special techniques can obtain three-dimensional images. The image in the TEM is generated by electrons that have passed through the sample, and to interact with its atoms have changed its energy and trajectory. This, at the end, has impacted on a photosensitive screen that has become in flashes, whose intensity has depended on its energy and form the image. Meanwhile, in the MER, the image has been normal type, although with less resolution. The electrons in the MER are focused on a small area of the sample in which have interacted with the atoms of this, and has generated a a series of signals, including the most used were the secondary electrons and characteristic X-rays. In both cases, an electron from beam has generated in the filament a collision against an electron of the sample and has given part of its energy to the degree of release of its atom and issued out of the sample; this has been called secondary electrons. X-rays have been generated when an electron of the same atom that has lost the secondary electron, but in an

    This perspective view shows the northern coastal plain of Costa Rica with the Cordillera Central, composed of a number of active and dormant volcanoes, rising in the background. This view looks toward the south over the Rio San Juan, which marks the boundary between Costa Rica and Nicaragua. The smaller river joining Rio San Juan in the center of the image is Rio Sarapiqui, which is navigable upstream as far inland as Puerto Viejo (Old Port) de Sarapiqui at the mountain's base. This river was an important transportation route for those few hardy settlers who first moved into this region, although as recently as 1953 a mere three thatched-roof houses were all that comprised the village of Puerto Viejo.This coastal plain is a sedimentary basin formed about 50 million years ago composed of river alluvium and lahar (mud and ash flow) deposits from the volcanoes of the Cordillera Central. It comprises the province of Heredia (the smallest of Costa Rica's seven) and demonstrates a wide range of climatic conditions, from warm and humid lowlands to cool and damp highlands, and including the mild but seasonally wet and dry Central Valley.This image was generated in support of the Central American Commission for Environment and Development through an agreement with NASA. The Commission involves eight nations working to develop the Mesoamerican Biological Corridor, an effort to study and preserve some of the most biologically diverse regions of the planet.This three-dimensional perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM) and an enhanced false-color Landsat 7 satellite image.

  14. The declining effect of sibling size on children's education in Costa Rica

    2014-12-01

    Full Text Available Background: Costa Rica experienced a dramatic fertility decline in the 1960s and 1970s. The same period saw substantial improvement in children's educational attainment in Costa Rica. This correlation is consistent with household-level quantity-quality tradeoffs, but prior research on quantity-quality tradeoff magnitudes is mixed, and little research has estimated quantity-quality tradeoff behaviors in Latin America. Objective: This study explores one dimension of the potential demographic dividend from the fertility decline: the extent to which it was accompanied by quantity-quality tradeoffs leading to higher educational attainment. Specifically, we provide the first estimate of quantity-quality tradeoffs in Costa Rica, analyzing the increase in secondary school attendance among Costa Rican children as the number of siblings decreases. Furthermore, we advance the literature by exploring how that tradeoff has changed over time. Methods: We use 1984 and 2000 Costa Rican census data as well as survey data from the Costa Rican Longevity and Healthy Aging Study (CRELES. To address endogenous family size, the analysis uses an instrumental variable strategy based on the gender of the first two children to identify the causal relationship between number of siblings and children's education. Results: We find that, among our earlier cohorts, having fewer siblings is associated with a significantly higher probability of having attended at least one year of secondary school, particularly among girls. The effect is stronger after we account for the endogeneity of number of children born by the mother. For birth cohorts after 1980 this relationship largely disappears. Conclusions: This study provides strong evidence for a declining quantity-quality (Q-Q tradeoff in Costa Rica. This result suggests one potential explanation for the heterogeneous findings in prior studies elsewhere, but more work will be required to understand why such tradeoffs might vary

    Propolis is produced by Apis mellifera bees from resins of plants that are found around the apiary. The chemical composition is highly variable and Costa Rica has reported without studies of characterization to define the types of propolis in the country. 119 samples were collected from beekeeping areas of the country. The spectrum of 1 H-NMR and its antioxidant activity against DPPH radical were measured. The spectra have been divided into 243 blocks of 0,04 ppm and processed with the Minitab software for multivariate analysis. 99 of the samples collected were used for construction of models for the valuation of the predictive ability of the model have been used coefficients of determination (R 2 ) of prediction by the software and the remaining 20 samples. The existence of three types of propolis with chemically different metabolomes were determined by principal component analysis (PCA). A prediction model was constructed by analysis of partial least squares (PLS). The prediction model has allowed to classify a propolis according to the level of antioxidant activity (AAO), high (type I and II) or low (type III) from the spectrum of 1 H-NMR. The R 2 has been 0.88 and R 2 prediction of 0, 718 for new samples. The nconiferyl benzoate of group I and nemorosone of the group II as two discriminated antioxidants among the groups I and II were isolated and high concentration levels of these compounds have been differentiated with respect to type III. This has allowed the construction of a linear discriminant model with a success rate of 100% for the samples used for formulation and 92,9 for the prediction of different samples. The classification systems could be applied to the standardization of the quality of propolis from Costa Rica for future medicinal or cosmetic applications that take advantage of its antioxidant properties. Also, the methylated derivative has isolated and identified of the nconiferyl benzoate thereof propolis than was obtained his counterpart

    Full Text Available Resumen La operación de las actividades económicas y su competitividad, analizadas desde una perspectiva de cadenas globales de mercancías, dependen del funcionamiento de los mercados de crédito, tanto nacionales como internacionales. La operación normal de los negocios requiere crédito para fortalecer sus recursos propios y hacer las compras de materia prima, insumos, pago de salarios e inversión. En todos los casos, el crédito puede ser utilizado para mejorar el diseño de productos, impulsar el acceso a nuevos mercados y aumentar la competitividad. A los productores de la región de Los Santos en Costa Rica se les reconoce por innovadores, y al café de la zona por ser un café de altura y de gran calidad. El artículo explora las necesidades de financiamiento de productores, beneficiadores y exportadores de café de Los Santos, sus fuentes de financiamiento y el uso dado a los recursos obtenidos. Entre las necesidades orientadas al mejoramiento de la competitividad se encontraron la renovación de cafetales entre los productores, el mantenimiento de proyectos y tecnología entre los beneficios y la generación de microbeneficios y búsqueda de nichos de mercado entre los exportadores. Abstract From a global commodity chains perspective, economic activities and their competitiveness depend upon the functioning of credit markets, both international and domestic. Current businesses operations require credit to enhance their own resources in order to buy raw material and inputs, pay wages and make investment. Credit may also be used to improve product design, enter new markets and boost competitiveness as a result. High altitude grown coffee from Los Santos, Costa Rica is widely known for its quality, and their growers as innovative. This paper addresses credit needs of coffee growers, processors and exporters in Los Santos, the credit sources they have access to, and the kind of uses the credit is given.

    A geologic map scale 1:50 000, stratigraphic and structural of the 509 km 2 of the Tapanti quadrangle is presented. The Tapanti quadrant is located in the central region of Costa Rica and belongs to the Central Costa Rica Deformed Belt (CCRDB). The CCRDB was a consequence of the interaction of the Cocos Ridge and the Western edge of the Panama microplate. Petrographic, geochemistry and paleontological analyzes were performed by selecting samples collected in the more than 100 field visits, with more than 300 outcrops raised. The geological information was compiled in a Geographical Information System. Lambert North coordinate system was employed. Aerial and topographic photographs from the TERRA Project 1997 and Digital Elevation Model were used. 18 rock samples were analyzed petrographically to discard altered samples. Rock samples were screened. The gravels or grains obtained were washed with deionized water in an ultrasonic stack. Gravel with signs of alteration were discarded by stereoscopic microscope. The powder obtained from the spraying of 25 mg of gravel each sample was melted and combined with Lithium tetraborate (Li2B4O7) and poured into glass discs. The discs were analyzed to determine concentrations of major elements and traced through of X-Ray Fluorescence in a Bruker S4 Pioner, and by a mass spectrometer (LA-ICP-MS) in a Micromass Platform ICP-MS, respectively. The oldest rocks mapped in this work are Miocene in age and they belongs to Pacacua, Pena Negra and Coris formations, than form the western edge of the Candelaria basin. Three igneous events were distinguished. First, the Miocene volcanic arc, which is represented by the rocks of La Cruz Formation and the clasts of Pacacua Formation. Another period of igneous activity was recorded in Grifo Alto and Doan formations and the Tapanti Intrusive, with an age range of 0.6-0.03 Ma. From a geochemical point of view a change in the composition of magmatism was remarkable between 10 to 6 Ma, expressed

    Full Text Available Dogs with the presumptive diagnosis of Chagas disease are commonly sent to our School of Veterinary Medicine by independent veterinarians. This prompted us to evaluate the prevalence of canine trypanosomiasis in some villages of the Central Valley of Costa Rica. A total of 54 dogs (21 males and 33 females from five rural villages, with ages between 3 months and 10 years old, were bled and submitted to three serological tests: indirect immunofluorescence, indirect hemagglutination and ELISA. Among all animals, 15 (27.7% revealed antibodies (6 pure bred and 9 mongrels and in 3 of them the parasite was also demonstrated by xenodiagnosis. All positive animals except 1, and 9 negative animals (control group were examined by X-rays and electrocardiography, revealing different degrees of cardiomegaly and ECG alteration, consistent with Chagas disease pathology in one dog (SA-11 of the infected ones. Examination of 50 inhabitants living in the houses where dogs and Triatoma dimidiata were found, yielded negative serological reactions. This was assumed to support the hypothesis that dogs are commonly infected by the oral route, a more effective means of infection compared with the vector transmission mechanism that occurs in humans.

  6. Light Diffusion in the Tropical Dry Forest of Costa Rica

    2016-06-01

    Leaf Area Index (LAI) has been defined as the total leaf area (one-sided) in relation to the ground. LAI has an impact on tree growth and recruitment through the interception of light, which in turn affects primary productivity. Even though many instruments exist for estimating LAI from ground, they are often laborious and costly to run continuously. Measurements of LAI from the field using traditional sensors (e.g., LAI-2000) require multiple visits to the field under very specific sky conditions, making them unsuitable to operate in inaccessible areas and forests with dense vegetation, as well as areas where persistent sunny conditions are the norm like tropical dry forests. With this context, we proposed a methodology to characterize light diffusion based on NDVI and LAI measurements taken from the field in two successional stages in the tropical dry forest of Santa Rosa National Park in Costa Rica. We estimate a "K" coefficient to characterize light diffusion by the canopy, based on field NDVI measurements derived from optical phenology instruments and MODIS NDVI. From the coefficients determined, we estimated LAI values and compared them with ground measurements of LAI. In both successional stages ground measurements of LAI had no significant difference to the tower-derived LAI and the estimated LAI from MODIS NDVI.

    Marine sediment samples from four coastal ecosystems in Costa Rica were taken between the years 2000-2002 and their iron, lead, copper and zinc concentrations were determined by the atomic absorption technique with flame or graphite furnace. In the Pacific coast, Culebra Bay (Papagayo Gulf), Gulf of Nicoya, and Golfito Bay (Dulce Gulf), were selected as representative sites, and Moin Bay, at the Caribbean coast. Mean metal concentrations for all ecosystems followed the same pattern: Fe> Zn> Cu> Pb. No temporal pattern was found for any metal. Iron and copper mean concentrations were higher in Golfito Bay (5.8% and 87 μg / g, respectively) and lower in Moin Bay (3.4% and 52 μg / g, respectively). Zinc mean concentration was also higher in Golfito Bay (96 μg / g), but lower in Culebra Bay (66 μg / g). Lead mean concentration was higher in Moin Bay (6.4 μg / g) and lower in Culebra Bay (3.0 μg / g). Lead highest concentrations occurred in the Caribbean and in Golfito Bay, and for the rest of the elements the maximum values were found in Golfito Bay. On the basis of data obtained in this work, Culebra Bay was considered a relatively unpolluted location; Golfito Bay was more contaminated, and Moin Bay and the Gulf of Nicoya showed an intermediate condition.

A total of 608 blood samples were collected during 2012 from 24 dairy farms located in the Northern regions of the provinces of Alajuela (15 and Heredia (9, and surveys were carried out to determine management practices in these farms. Serum samples were analyzed by enzyme-linked immunosorbent assay (ELISA to detect antibodies against C. abortus (sensitivity 100.0%, specificity 99.7%. Only one serum yielded positive results (S/P 62 %, two sera weak positive results (S/P 51% and 52%, respectively, while the remaining sera (n=605 were negative in ELISA. Six months later, 22 animals that showed S/P values >22% in ELISA were analyzed again, yielding all negative results. Blood, milk, conjunctival and vulvar swabs from these animals were analyzed by Polymerase Chain Reaction (PCR, and only one vulvar swab tested positive for Chlamydia spp. The analysis of the management practices and results obtained with ELISA and PCR lead us to conclude that C. abortus is not significantly present (<0.5% in dairy farms in the Northern regions of the provinces of Heredia and Alajuela in Costa Rica.

    Turrialba volcano is an active composite stratovolcano that is located approximately 40 km east of San Jose, Costa Rica. Seismic activity and degassing have increased since 2005, and gas compositions reflect further increased activity since 2007 peaking in January 2010 with a phreatic eruption. Gas fumes dispersed by trade winds toward the west, northwest, and southwest flanks of Turrialba volcano have caused significant vegetation kill zones, in areas important to local agriculture, including dairy pastures and potato fields, wildlife and human populations. In addition to extensive vegetative degradation is the potential for soil and water contamination and soil erosion. Summit fumarole temperatures have been measured over 200 degrees C and gas emissions are dominated by SO2; gas and vapor plumes reach up to 2 km (fumaroles and gases are measured regularly by OVSICORI-UNA). A recent network of passive air sampling, monitoring of water temperatures of hydrothermal systems, and soil pH measurements coupled with measurement of the physiological status of surrounding plants using gas exchange and fluorescence measurements to: (1) identify physiological correlations between leaf-level gas exchange and chlorophyll fluorescence measurements of plants under long term stress induced by the volcanic gas emissions, and (2) use measurements in tandem with remotely sensed reflectance-derived fluorescence ratio indices to track natural photo inhibition caused by volcanic gas emissions, for use in monitoring plant stress and photosynthetic function. Results may prove helpful in developing potential land management strategies to maintain the biological health of the area.

    A cross-sectional survey of a convenient sample of domestic cats from Costa Rica's greater metropolitan area was carried out to determine the prevalence of antibodies against feline herpesvirus type 1 (FHV-1), feline parvovirus (FPV), feline immunodeficiency virus (FIV) and antigens of feline leukemia virus (FeLV). Blood samples were collected from at least 96 cats from June 1998 to December 2001; data related to the individual cats and household variables were obtained using a questionnaire. Antibodies against FHV-1 were found in 71.9% of the cats sampled, but only 25.0% of them had a history of previous vaccination. The prevalence of FPV was 92.8%, and all positive cats showed protective antibodies titres; however, only 16.5% of them were previously vaccinated. Antigens of FeLV were detected in 16.7% of the sampled cats; 11 (64.7%) of the 17 positive cats were older than 1 year at the time of testing. No differences were found between the percentage of seropositive males and females. Antibodies against FIV were detected in 8.8% of the samples tested; 8 (88.8%) of the seropositive cats were older than 1 year of age, and a greater proportion of seropositive males (66.6%) was found.

    While anthropogenic impacts on parasitism of wildlife are receiving growing attention, whether these impacts vary in a sex-specific manner remains little explored. Differences between the sexes in the effect of parasites, linked to anthropogenic activity, could lead to uneven sex ratios and higher population endangerment. We sampled 1108 individual bats in 18 different sites across an agricultural mosaic landscape in southern Costa Rica to investigate the relationships between anthropogenic impacts (deforestation and reductions in host species richness) and bat fly ectoparasitism of 35 species of Neotropical bats. Although female and male bat assemblages were similar across the deforestation gradient, bat fly assemblages tracked their hosts closely only on female bats. We found that in female hosts, parasite abundance per bat decreased with increasing bat species richness, while in male hosts, parasite abundance increased. We hypothesize the differences in the parasite-disturbance relationship are due to differences in roosting behavior between the sexes. We report a sex-specific parasite-disturbance relationship and argue that sex differences in anthropogenic impacts on wildlife parasitism could impact long-term population health and survival.

    The Costa Rican water regulatory framework (WRF) (2007), expresses the national concern about the degradation of surface water quality observed in the country since several years. Given the urgency of preserving and restoring the surface water bodies, and facing the need of defining a monitoring tool to classify surface water pollution, the Costa-Rican WRF relies on two water quality indexes: the so-called "Dutch Index" (D.I) and the Biological Monitoring Working Party adapted to Costa Rica (BMWP'CR), allowing an "easy" physicochemical and biological appraisal of the water quality and the ecological integrity of water bodies. Herein, we intend to evaluate whether the compound of water quality indexes imposed by Costa Rican legislation, is suitable to assess rivers local and global anthropogenic pressure and environmental conditions. We monitor water quality for 7 points of Liberia River (northern pacific region - Costa Rica) from March 2013 to July 2015. Anthropogenic pressures are characterized by catchment land use and riparian conditions. Environmental conditions are built from rainfall daily series. Our results show (i) the difficulties to monitor new sites following the recent implementation of the WRF; (ii) the statistical characteristics of each index; and (iii) a modelling tentative of relationships between water quality indexes and explanatory factors (land-use, riparian characteristics and climate conditions).

    Pseudocercospora fijiensis is the causal pathogen of black Sigatoka, a devastating disease of banana that can cause 20 to 80% yield loss in the absence of fungicides in banana crops. The genetic structure of populations of P. fijiensis in Costa Rica was examined and compared with Honduran and global populations to better understand migration patterns and inform management strategies. In total, 118 isolates of P. fijiensis collected from Costa Rica and Honduras from 2010 to 2014 were analyzed using multilocus genotyping of six loci and compared with a previously published global dataset of populations of P. fijiensis. The Costa Rican and Honduran populations shared haplotype diversity with haplotypes from Southeast Asia, Oceania, and the Americas but not Africa for all but one of the six loci studied. Gene flow and shared haplotype diversity was found in Honduran and Costa Rican populations of the pathogen. The data indicate that the haplotypic diversity observed in Costa Rican populations of P. fijiensis is derived from dispersal from initial outbreak sources in Honduras and admixtures between genetically differentiated sources from Southeast Asia, Oceania, and the Americas.

  19. Hydro and geothermal electricity as an alternative for industrial petroleum consumption in Costa Rica

    Energy Technology Data Exchange (ETDEWEB)

    Mendis, M.; Park, W.; Sabadell, A.; Talib, A.

    1982-04-01

    This report assesses the potential for substitution of electricity for petroleum in the industrial/agro-industrial sector of Costa Rica. The study includes a preliminary estimate of the process energy needs in this sector, a survey of the principal petroleum consuming industries in Costa Rica, an assessment of the electrical technologies appropriate for substitution, and an analysis of the cost trade offs of alternative fuels and technologies. The report summarizes the total substitution potential both by technical feasibility and by cost effectiveness under varying fuel price scenarios and identifies major institutional constraints to the introduction of electric based technologies. Recommendations to the Government of Costa Rica are presented. The key to the success of a Costa Rican program for substitution of electricity for petroleum in industry rests in energy pricing policy. The report shows that if Costa Rica Bunker C prices are increased to compare equitably with Caribbean Bunker C prices, and increase at 3 percent per annum relative to a special industrial electricity rate structure, the entire substitution program, including both industrial and national electric investment, would be cost effective. The definition of these pricing structures and their potential impacts need to be assessed in depth.

  20. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Costa Rica

    International Nuclear Information System (INIS)

    1977-08-01

    Most parts of Costa Rica, except for the Quaternary volcanic belt, have neither been studied or mapped in detail. Concerning past exploration limited uranium exploration took place in the late 1960's but details are lacking. No additional information is available. A bibliography of Costa Rican geology (Dengo, 19t>2a) and the metallogenic map of Central America (1CAITI, 1970) do not report any uranium occurrences. Data on current exploration activities for uranium are lacking. Mining is essentially regulated by a 1953 code and a 1964 supplement, but the production and use of radioactive materials are controlled by the Costa Rican Atomic Energy Commission. New raining and petroleum laws reportedly are being considered. Mining rights are available with few restrictions to foreign nationals and corporations. Costa Rica contains no rocks older than Cretaceous. The Mesozoic continental clastic sequences of Honduras and northern Nicaragua do not extend this far south. The massive intrusions of acidic granites and syenites in the Talamanca ranges are probably older than the oldest formations now seen adjacent to them and could not have contributed to their mineralization except through weathering. There may be a faint possibility for uranium deposition in lodes and fracture zones within the granitic rocks, but no such deposits have been reported. Insofar as the sediments are concerned, only the shallow water faces of the marine sediments of the Caribbean coastal region offer the remotest possibilities. The uranium potential of Costa Rica is estimated, at less than 1,000 tonnes

    Full Text Available Agricultura, recursos naturales, medio ambiente y desarrollo sostenible en Costa Rica. La agricultura sostenible en Costa Rica debe reconocer la necesidad de intensificar la productividad como medio de soportar la acelerada demanda creada por el incremento poblacional, pero al mismo tiempo debe prever el mejor uso y conservación de los recursos naturales. Sin recursos naturales no hay agricultura y sin ésta no hay seguridad alimentaria. Es de esperar que Costa Rica pueda satisfacer la demanda creciente de alimentos y otros productos agrícolas; evitando el acelerado proceso de degradación que sufren nuestros suelos y bosques. El proceso de agricultura sostenible en Costa Rica y otros países de la región, presenta un incremento en la demanda de tierras y recursos naturales; lo cual suscita competencias y agudos conflictos sociales, económicos y ecológicos. Costa Rica debe plantearse una estrategia de desarrollo sostenible que contemple los efectos asociados del crecimiento demográfico, la seguridad alimentaria, la protección de la biodiversidad, la regeneración de los ecosistemas, el desarrollo de tecnologías amigables con el ambiente, la regulación sobre el acceso a los recursos naturales y la formación de capital humano

    Full Text Available A agricultura desempenha papel importante na economia brasileira. Um elemento central para o desenvolvimento dessa atividade tanto no que tange ao crescimento econômico quanto social é a inovação. Nesse contexto, a proposta deste estudo objetiva analisar as inovações de produto, processo, organizacional e de marketing na agricultura brasileira. O estudo é de cunho teórico e analisa 32 artigos relacionados com o tema, selecionados a partir de bases de dados e de periódicos focados em inovação. Os resultados possibilitaram a criação de um esquema representativo da inovação na agricultura brasileira cujos componentes são os objetivos dos artigos, o tipo de estudo realizado, os conceitos e tipos de inovações adotados, as ferramentas e procedimentos utilizados para inovar, as principais entregas dos autores e a identificação das inovações como incremento ou diferenciação das commodities agrícolas. Concluiu-se que as pesquisas tratam dos diferentes tipos de inovação, conforme classificação do Manual de Oslo, os objetivos são voltados para aspectos técnicos ou sociais e o predomínio é de trabalhos de campo. Em suma, a inovação vem sendo acrescida tanto nas questões da produtividade quanto nas relações do homem com a terra e do desenvolvimento sustentável.

    Full Text Available O objetivo deste artigo, apoiado nos principais indicadores da economia global e nacional, é promover uma análise dos efeitos da crise mundial e as perspectivas de crescimento da economia brasileira no período de 2013-2015. O referencial teórico está apoiado nas Teorias Keynesiana, Neoinstitucionalista e das Finanças Públicas. Trata-se de um artigo bibliográfico, descritivo e qualitativo, cujas discussões estão baseadas nas projeções contidas nos relatórios das principais instituições multilaterais e nacionais brasileiras, em especial nas variáveis econômicas mais relevantes como o crescimento da economia mundial, do comportamento do nível de emprego e da inflação. Os resultados das discussões, a partir das análises dos documentos citados, evidenciam que a crise econômica mundial continua impactando de forma preocupante na maioria dos países, em especial, dos países membros da Zona do Euro e Estados Unidos, e que o desempenho da economia brasileira deverá crescer num ritmo menor nos próximos anos. Essas constatações permite concluir que se faz necessário a definição de um diagnóstico consistente para o Brasil, que permita uma mudança estrutural no potencial de expansão da economia do país, em especial, preparando de forma mais adequada o seu ambiente macro e microeconômico.

    Full Text Available O objetivo do presente estudo é analisar o processo de internacionalização de empresas brasileiras, incluindo as motivações para a internacionalização, os modos de entrada selecionados e as dificuldades encontradas nesse processo. O tema escolhido justifica-se pela importância da gestão internacional para empresas brasileiras no momento em que o país se encontra. Na revisão da literatura são discutidos estudos que tratam do processo de entrada em mercados externos, e mais especificamente da internacionalização de empresas brasileiras. Realizou-se pesquisa empírica, exploratória e qualitativa. Para a coleta de dados, foi utilizada a entrevista em profundidade, a qual tinha por base um roteiro. Como procedimento analítico, adotou-se a análise de conteúdo. Participaram da pesquisa dez empresas que têm sede no Brasil, adotaram o sistema de franquias no país e se internacionalizaram. Tais empresas fazem parte da Associação Brasileira de Franchising (ABF, que apoiou a pesquisa. O setor de franquias foi escolhido porque o Brasil é um dos países mais avançados do mundo em franquias e esse sistema é reconhecido como importante impulsionador do processo de globalização. Foram entrevistados o dono da empresa ou o executivo da área de marketing e/ou o responsável pela área internacional. Os resultados da pesquisa empírica evidenciam que, apesar de entrantes tardias, as empresas analisadas não pareceram atrasadas em termos de capacitação gerencial e demonstram possuir competências tecnológicas. É fato, contudo, que elas demoraram a se internacionalizar por possuírem ainda um vasto mercado interno para conquistar. Adotar uma visão global é muito importante, mesmo que se prefira uma abordagem gradual de internacionalização.

    Full Text Available O objetivo central do presente artigo é analisar a dinâmica inflacionária brasileira e medir o grau de inércia em tal dinâmica. De início, nós apresentamos resultados de simulação de Monte Carlo sobre o desempenho em amostras finitas de diferentes variantes da razão de variâncias, uma medida comumente utilizada para a mensuração de persistência de choques no longo prazo. As simulações são realizadas sob inovações normais e não-normais e também com e sem outliers e inliers. Os resultados favorecem uma particular variante robusta da razão de variâncias proposta neste artigo. Os resultados empíricos para o Brasil indicam que o grau de inércia inflacionária neste país é substancialmente maior do que aquele encontrado por Campêlo e Cribari-Neto (Revista Brasileira de Economia, 57, 713-739, 2003; de fato, em alguns períodos da história econômica brasileira recente nós encontramos inércia plena. Todavia, o grau de inércia inflacionária após a implementação do Plano Real é de segunda ordem. Nós analisamos também as dinâmicas inflacionárias da Argentina, Chile e México.The chief goal of this paper is to analyze the Brazilian inflationary dynamics, and to measure the degree of inertia in such dynamics. To that end, we start by reporting Monte Carlo simulation results on the finite-sample performance of different variants of the variance ratio, a well know measure of long-run persistence of shocks. The simulations are performed under normal and nonnormal innovations, and also with and without outliers and inliers. Overall, the results favor a robust variant of the variance ratio we propose. The empirical results for Brazil suggest that the degree of inertia in this country is substantially larger than what was found by Campêlo and Cribari-Neto (Revista Brasileira de Economia 57, 713-739, 2003; indeed, in several periods of the recent economic history we find full inertia. However, the degree of inertia since

    Tatiana Albanez

    2012-04-01

    Full Text Available O objetivo principal deste trabalho é analisar se a presença de importantes fatores institucionais brasileiros, como o acesso a fontes e linhas diferenciadas de financiamento, afeta a significância estatística e econômica da assimetria informacional, principal pressuposto da teoria de pecking order, na determinação da estrutura de capital de empresas brasileiras. Para tanto, foram utilizadas variáveis de controle, variáveis representativas de fatores institucionais e de assimetria informacional num painel de dados referente a empresas brasileiras de setores industriais, cujas ações foram negociadas na Bovespa, no período 1997-2007. Como principais resultados encontra-se que as variáveis tamanho, tangibilidade, rentabilidade e risco são importantes determinantes da estrutura de capital das empresas analisadas, sendo também significativa a participação de linhas diferenciadas no endividamento dessas empresas. Em resposta ao objetivo da pesquisa, verifica-se que a assimetria informacional não perde significância estatística e econômica no modelo proposto, após a inclusão de variáveis representativas de fatores institucionais, o que evidencia a importância da assimetria informacional na determinação da estrutura de capital de empresas brasileiras. O sinal negativo encontrado apoia a teoria de pecking order, na qual essas empresas seriam menos endividadas devido à possibilidade de captarem recursos por meio da emissão de ações. Ressalta-se que as proxies utilizadas para representar o atributo assimetria informacional constituem uma limitação da pesquisa. Em razão disso, sugere-se, para trabalhos futuros, a utilização de outras variáveis, com o propósito de verificar a consistência dos resultados aqui encontrados, bem como a análise da influência da assimetria informacional sobre o custo de capital de empresas brasileiras, com o intuito de verificar se empresas consideradas com menor assimetria informacional

    The African hedgehog is one of the newly imported exotic pets which have been observed with increasing regularity in veterinary clinics in Costa Rica. Despite their popularity, information about their diseases is scarce. Within skin diseases of hedgehogs, mange caused by Caparinia spp. is a common diagnosis in other countries. Two adult African hedgehogs, one male and one female, were brought to a private clinic in Heredia, Costa Rica, with chronic pruritic dermatitis, scabs, nearly complete loss of spines, lethargy, dehydration, and weight loss. During physical exam, deposits of dry seborrhea were taken and processed for diagnosis. Microscopic examination revealed psoroptid mites identified as Caparinia tripilis. This is the first report of the presence of Caparinia tripilis in Costa Rica and, to the authors' knowledge, the rest of Central America.

  11. Plastic paradise: transforming bodies and selves in Costa Rica's cosmetic surgery tourism industry.

    Science.gov (United States)

    Ackerman, Sara L

    2010-10-01

    Long popular as a nature tourism destination, Costa Rica has recently emerged as a haven for middle class North Americans seeking inexpensive, state-of-the-art cosmetic surgery. This paper examines "cosmetic surgery tourism" in Costa Rica as a form of medicalized leisure, situated in elite private spaces and yet inextricably linked to a beleaguered national medical program. Through historical context and ethnographic analysis of activities at medical hotels and clinics, I describe how the recovery industry operates on the embodied subjectivities of visiting patients and their local caretakers. Recovery sociality and healing landscapes facilitate patients' transition through a period of post-surgical liminality and provide nostalgic transport to an imagined medical arcadia, while clinicians are attracted by a neoliberal promise of prosperity and autonomy. Ultimately, Costa Rica's transformation into a paradise of medical consumption and self-optimization is contingent on a mythology that obscures growing uncertainties and inequities in the nation's broader medical landscape.

    Full Text Available OBJETIVO: Descrever as aposentadorias por invalidez decorrente de dor nas costas. MÉTODOS: Estudo descritivo com dados do Sistema Único de Informações de Benefícios e dos Anuários Estatísticos da Previdência Social em 2007. A taxa de incidência de dor nas costas como causa das aposentadorias por invalidez foi calculada segundo as variáveis idade e sexo, nos estados. Os dias de trabalho perdidos por invalidez decorrente de dor nas costas foram calculados segundo atividade profissional. RESULTADOS: A dor nas costas idiopática foi a primeira causa de invalidez entre as aposentadorias previdenciárias e acidentárias. A maioria dos beneficiários residia em área urbana e era comerciário. A taxa de incidência de dor nas costas como causa das aposentadorias por invalidez no Brasil foi de 29,96 por 100.000 contribuintes. Esse valor foi mais elevado entre os homens e entre as pessoas mais velhas. Rondônia exibiu taxa quatro vezes superior ao esperado (RT = 4,05 e a segunda maior taxa, referente à Bahia, foi de aproximadamente duas vezes o esperado (RT = 2,07. Os comerciários foram responsáveis por 96,9% dos dias perdidos por invalidez. CONCLUSÕES: A dor nas costas foi uma importante causa de invalidez em 2007, sobretudo entre comerciários, com grandes diferenças entre os estados.

Os mosquiteiros impregnados tiveram excelente receptividade pela população local. No entanto, a aderência foi muito baixa, principalmente pelos adultos maiores de 15 anos de idade e, durante a estiagem. O preço do mosquiteiro impregnado foi calculado em US$18,83 para casal e, em US$13,82, para solteiro. Apesar das vantagens econômicas do emprego dos mosquiteiros impregnados em larga escala, desde que subsidiados pelas agências governamentais, a baixa aderência verificada, aliada aos fatores epidemiológicos locais, não permitem indicar o uso de mosquiteiros impregnados como medida de proteção em massa na Amazônia.In 1992 during a trial with deltamethrin-impregnated bed nets conducted in Porto Murtinho, municipality of Costa Marques, Rondonia, in the Brazilian Amazon, we investigated community compliance and the economic aspects capable of reducing the impact of this intervention on malaria morbidity. Impregnated bed nets were well accepted by the local population. However, compliance was found to be very low among adults over 15 years of age and mainly during the dry season. The cost of impregnated bed nets was US$18.83 for double-bed nets and US$13.82 for single bed nets. Despite the economic advantages of using impregnated bed nets subsidized by the government, the low compliance and local epidemiological factors do not allow to indicate the use of impregnated bed nets for mass malaria control in the Amazon region.

    This perspective view shows the capital city of San Jose, Costa Rica, in the right center of the image (gray area). Rising behind it are the volcanoes Irazu, 3402 meters high (11,161 feet) and Turrialba, 3330 meters high (10,925 feet.)Irazu is the highest volcano in Costa Rica and is located in the Irazu Volcano National Park, established in 1955. There have been at least 23 eruptions of Irazu since 1723, the most recent during 1963 to 1965. This activity sent tephra and secondary mudflows into cultivated areas, caused at least 40 deaths, and destroyed 400 houses and some factories.This image was generated in support of the Central American Commission for Environment and Development through an agreement with NASA. The Commission involves eight nations working to develop the Mesoamerican Biological Corridor, an effort to study and preserve some of the most biologically diverse regions of the planet.This three-dimensional perspective view was generated using topographic data from the Shuttle Radar Topography Mission (SRTM) and an enhanced false-color Landsat 7 satellite image. Colors are from Landsat bands 5, 4, and 2 as red, green and blue, respectively. Topographic expression is exaggerated 2X.Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter resolution of most Landsat images and will substantially help in analyses of the large and growing Landsat image archive. The Landsat 7 Thematic Mapper image used here was provided to the SRTM by the United States Geological Survey, Earth Resources Observation Systems (EROS) Data Center, Sioux Falls, South Dakota.Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on February 11,2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM

    Full Text Available 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 = lambda a t + gamma S12 + a t typeEn este trabajo, se analizaron los datos de desembarque de tiburón de la flota pesquera artesanal en el Pacífico costarricense entre 1988 y 1997.

Investigamos os anos de ditadura militar (1964-1985. O foco da análise é a chamada canção de protesto, gênero musical caracterizado por críticas estético-cultural, político-ideológica e social aos governos militares. Tomando como referencial teórico os estudos de ideologia e filosofia da linguagem de Mikhail Bakhtin, evidenciamos que a canção de protesto retratou elementos dos contextos econômico, político e social, e propiciou a difusão de hábitos e ideologias alimentares saudáveis ou não saudáveis, contribuindo para a construção da identidade alimentar brasileira.

  18. Análise econômica da primeira Lei de Patentes brasileira

    Directory of Open Access Journals (Sweden)

    Andrea Felippe Cabello

    Full Text Available Resumo O Brasil foi um dos primeiros países a ter uma lei de patentes e um dos únicos a conceder prazos de duração da patente de acordo com a qualidade da invenção. Este trabalho analisa um banco de dados inédito com todos os 783 privilégios industriais concedidos sob a vigência da primeira lei de patentes brasileira entre 1830 e 1882. Os resultados mostram que a atividade inventiva esteve conectada à estrutura econômica e social da época e que a escassez de mão de obra incentivou a invenção de máquinas e equipamentos para o setor cafeicultor. O número de patentes apenas começou a se elevar a partir de 1870, quando a economia brasileira passou por grandes mudanças que levaram ao seu desenvolvimento, evidenciando que pouco resultado surge quando se institui uma lei de patentes em um ambiente de estagnação econômica. Mesmo assim, a lei revelou-se o mecanismo menos dispendioso para estimular a atividade inventiva no Brasil do século XIX.

Procuro sustentar meu argumento a partir da leitura de obras de pensadores da história e da cultura brasileiras considerados “de esquerda” ao mesmo tempo em que pontuo os limites de suas análises, ou seja, o silenciamento sobre a opressão das mulheres e questões de gênero. A seguir, examino a persistência de diversas formas do antifeminismo no campo das Letras a fim de compreender o estatuto da crítica feminista no campo dos estudos literários e as razões de sua invisibilidade, com considerações sobre conquistas e limitações de suas práticas.

Essas tensões dizem respeito ao golpe militar que inibiu melhorias no setor educacional, ao estudo exclusivo nas escolas de obras consideradas canônicas e ao estudo conteudista de literatura exigido pelos exames vestibulares. Esse é um debate importante, pois o ensino atual de literatura nas escolas impede a formação de estudantes capazes de analisar e interpretar um texto literário e de compreender o contexto histórico e sociológico de um país. Iremos, portanto, detalhar esses problemas e apresentaremos como o ensino de literatura brasileira pode ser importante para a percepção por parte dos alunos dos problemas sociais e consequentemente criar estudantes críticos.

    The presence of resistance to clethodim in Poa annua populations was observed in onion fields in the highlands of Cartago, Costa Rica. Two experiments were conducted; the first one was carried out, in 2007, in a greenhouse at the Fabio Baudrit Moreno Agricultural Experiment Station (EEAFBM, in Spanish), with seeds of plants from a farm where clethodim has exercised good control (S population), and from another farm where clethodim has showed a deficient control (R population). Both S and R populations were treated with different doses of clethodim (0,5X, 1,0X, 1,5X and 2,0X), being X the recommended commercial dose. In this experiment, control of the R population was 44% and 17% at doses of 1.5X and 2.0X, respectively, whereas control of the S population was 100% at either of those doses. The second experiment was carried out in 2009, seeds of two other P. annua populations were collected in a similar way: one population from an area where weed control has been satisfactory (S), and the other population from an area of the farm where control was deficient (R). Seeds were sown, depending on the type, in plastic pots and sprayed with clethodim at doses of: 0. 1X, 2X, 4X, 8X, and 16X. There were significant differences in the reactions to clethodim of both P. annua populations The S population showed a higher percentage of control and less surviving plants than the R population. Several plants of the R population resisted up to 16X commercial doses of clethodim. Results of both experiments suggest the presence of P. annua populations resistant to clethodim. (author) [es

  5. Basic limnology of fifty-one lakes in Costa Rica.

    2003-03-01

    We visited 51 lakes in Costa Rica as part of a broad-based survey to document their physical and chemical characteristics and how these relate to the mode of formation and geographical distribution of the lakes. The four oxbow lakes were low in elevation and tended to be turbid, high in conductivity and CO2, but low in dissolved O2; one of these, L. Gandoca, had a hypolimnion essentially composed of sea water. These were similar to the four wetland lakes, but the latter instead had low conductivities and pH, and turbidity was often due to tannins rather than suspended sediments. The thirteen artificial lakes formed a very heterogenous group, whose features varied depending on local factors. The thirteen lakes dammed by landslides, lava flows, or lahars occurred in areas with steep slopes, and were more likely to be stratified than most other types of lakes. The eight lakes that occupy volcanic craters tended to be deep, stratified, clear, and cool; two of these, L. Hule and L. Río Cuarto, appeared to be oligomictic (tending toward meromictic). The nine glacial lakes, all located above 3440 m elevation near Cerro Chirripó, were clear, cold, dilute, and are probably polymictic. Cluster analysis resulted in three significant groups of lakes. Cluster 1 included four calcium-rich lakes (average 48 mg l-1), Cluster 2 included fourteen lakes with more Si than Ca+2 and higher Cl- than the other clusters, and Cluster 3 included the remaining thirty-three lakes that were generally less concentrated. Each cluster included lakes of various origins located in different geographical regions; these data indicate that, apart from the high-altitude glacial lakes and lakes in the Miravalles area, similarity in lake chemistry is independent of lake distribution.

    The degree of inter-regional genetic diversity is explored in cattle of Costa Rica. 1498 DNA samples were collected of eight different regions of the country during the year 2013. Allelic frequencies and major population genetic parameters are calculated for eighteen microsatellite markers. An analysis of molecular variance is performed. The genetic distances between cattle of different regions are calculated. A high degree of diversity, with an average number of 14,6±1,01 alleles observed and 5,6+0,37 effective alleles per marker is observed at the national level. The heterozygosity observed (Ho) has been 0,76±0,01 and the expected (He) 0,81±0,01. Polymorphic information content (PIC) and inbreeding index (F_I_S) have been of 0,79±0,06 and 0,06±0,004, respectively. At the regional level, HO has varied from 0,73 ± 0,02 in the Central Sur region to 0,78 ±0,01 in the Huetar Norte region. Three clearly differentiated groups are shown by the dendrogram , with the Central Metropolitana and Central Occidental regions in a group: Huetar Caribe, Central Sur, Pacifico Central and Chorotega in a second group; and Huetar Norte and Brunca in a third intermediate group. Estimates of genetic differentiation R_S_T have been significant between regions of different groups and among regions of the same group have remained without being significant. Genetic differences between regions are related with differentiated proliferation of racial types according to their adaptability to the agroecological conditions and production systems prevailing in each region.

    We are currently developing a series of drones and associated instrumentation to study Turrialba volcano in Costa Rica. This volcano has shown increasing activity during the last 20 years, and the volcano is currently in a state of heightened unrest as exemplified by recent explosive activity in May-August 2016. The eruptive activity has made the summit area inaccessible to normal gas monitoring activities, prompting development of new techniques to measure gas compositions. We have been using two drones, a DJI Spreading Wings S1000 octocopter and a Turbo Ace Matrix-i quadcopter, to airlift a series of instruments to measure volcanic gases in the plume of the volcano. These instruments comprise optical and electrochemical sensors to measure CO2, SO2, and H2S concentrations which are considered the most significant species to help forecast explosive eruptions and determine the relative proportions of magmatic and hydrothermal components in the volcanic gas. Additionally, cameras and sensors to measure air temperature, relative humidity, atmospheric pressure, and GPS location are included in the package to provide meteorological and geo-referenced information to complement the concentration data and provide a better picture of the volcano from a remote location. The integrated payloads weigh 1-2 kg, which can typically be flown by the drones in 10-20 minutes at altitudes of 2000-4000 meters. Preliminary tests at Turrialba in May 2016 have been very encouraging, and we are in the process of refining both the drones and the instrumentation packages for future flights. Our broader goals are to map gases in detail with the drones in order to make flux measurements of each species, and to apply this approach at other volcanoes.

    Full Text Available The population of Costa Rica (CR represents an admixture of major continental populations. An investigation of the CR population structure would provide an important foundation for mapping genetic variants underlying common diseases and traits. We conducted an analysis of 1,301 women from the Guanacaste region of CR using 27,904 single nucleotide polymorphisms (SNPs genotyped on a custom Illumina InfiniumII iSelect chip. The program STRUCTURE was used to compare the CR Guanacaste sample with four continental reference samples, including HapMap Europeans (CEU, East Asians (JPT+CHB, West African Yoruba (YRI, as well as Native Americans (NA from the Illumina iControl database. Our results show that the CR Guanacaste sample comprises a three-way admixture estimated to be 43% European, 38% Native American and 15% West African. An estimated 4% residual Asian ancestry may be within the error range. Results from principal components analysis reveal a correlation between genetic and geographic distance. The magnitude of linkage disequilibrium (LD measured by the number of tagging SNPs required to cover the same region in the genome in the CR Guanacaste sample appeared to be weaker than that observed in CEU, JPT+CHB and NA reference samples but stronger than that of the HapMap YRI sample. Based on the clustering pattern observed in both STRUCTURE and principal components analysis, two subpopulations were identified that differ by approximately 20% in LD block size averaged over all LD blocks identified by Haploview. We also show in a simulated association study conducted within the two subpopulations, that the failure to account for population stratification (PS could lead to a noticeable inflation in the false positive rate. However, we further demonstrate that existing PS adjustment approaches can reduce the inflation to an acceptable level for gene discovery.

    Costa Rica’s most populated area, the Central valley, has lost much of its natural habitat, and the little that remains has been altered to varying degrees. Yet few studies have been conducted to assess the need for conservation in this area. We present preliminary inventories of plants, butterflies, and day-flying moths of the Reserva Ecológica Leonelo Oviedo (RELO), a small Premontane Moist Forest preserve within the University of Costa Rica campus, located in the urbanized part of the vall...

    Full Text Available Price transmission analysis is an increasing research topic, especially for price taking countries such as Costa Rica. We describe the beef supply chain and provide a numerical implementation of Vector Error Correction Model (VECM of price transmission for the meat market in order to observe the relationship between import prices of meat and their effects on national retail prices. To restore equilibrium, retail prices correct 8% of the error term monthly. Since the meat imports market of Costa Rica is complex, the analysis of others business partners as Nicaragua should be included in order to compare the influence of these in local retail prices

  16. Using Social Networks to Educate Seismology to Non-Science Audiences in Costa Rica

    2013-12-01

    Costa Rica has a very high rate of seismicity with 63 damaging earthquakes in its history as a nation and 12 felt earthquakes per month on average. In Costa Rica, earthquakes are part of everyday life; hence the inhabitants are highly aware of seismic activity and geological processes. However, formal educational programs and mainstream media have not yet addressed the appropriate way of educating the public on these topics, thus myths and misconceptions are common. With the increasing influence of social networks on information diffusion, they have become a new channel to address this issue in Costa Rica. The National Seismological Network of Costa Rica (RSN) is a joint effort between the University of Costa Rica and the Costa Rican Institute of Electricity. Since 1973, the RSN studies the seismicity and volcanic activity in the country. Starting on January 2011 the RSN has an active Facebook Page, in which felt earthquakes are reported and information on Seismology, geological processes, scientific talks, and RSN activities are routinely posted. Additionally, RSN gets almost instantaneous feedback from RSN followers including people from all rural and urban areas of Costa Rica. In this study, we analyze the demographics, geographic distribution, reach of specific Facebook posts per topic, and the episodic growth of RSN followers related to specific seismic events. We observe that 70 % of the RSN users are between ages from 18 to 34. We consistently observe that certain regions of the country have more Facebook activity, although those regions are not the most populated nor have a high connectivity index. We interpret this pattern as the result of a higher awareness to geological hazards in those specific areas. We notice that educational posts are as well 'liked' as most earthquake reports. For exceptional seismic events, we observe sudden increments in the number of RSN followers in the order of tens of thousands. For example, the May 2013 Sixaola earthquake (Mw

  17. Culture of Fear and Control in Costa Rica (II). Talk of Crime and Social Changes

    OpenAIRE

    Huhn, Sebastian

    2009-01-01

    The Costa Rican talk of crime is fundamentally based on the assumption that a formerly explicitly nonviolent nation has been transformed into a battleground for social violence—that is, on the belief that an alarming “crime wave” is occurring today while there was no crime at all in the past. On the basis of this assumption, the fear of crime and the call for zero tolerance and drastic law enforcement actions have been increasing. In this paper I discuss the Costa Rican talk of crime from a h...

    For several years, the University of Costa Rica, NASA Centers (e.g., JPL, ARC, GSFC/WFF, GRC) & NASA contractors-partners have made regular in situ measurements of aerosols & gases at Turrialba Volcano in Costa Rica, with aerostats (e.g., tethered balloons & kites), & free-flying fixed wing UAVs (e.g., Dragon Eye, Vector Wing 100, DELTA 150), at altitudes up to 12.5Kft ASL within 5km of the summit. Onboard instruments included gas detectors (e.g., SO2, CO2), visible & thermal IR cameras, air samplers, temperature pressure & humidity sensors, particle counters, & a nephelometer. Deployments are timed to support bimonthly overflights of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) onboard the NASA Terra satellite (26 deployments to date). In situ observations of dilute plume SO2 concentrations (~1-20ppmv), plume dimensions, and associated temperature, pressure, & humidity profiles, validate detailed radiative transfer-based SO2 retrievals, as well as archive-wide ASTER band-ratio SO2 algorithms. Our recent UAV-based CO2 observations confirm high concentrations (e.g., ~3000ppmv max at summit jet), with 1000-1500ppmv flank values, and essentially global background CO2 levels (400ppmv) over distal surroundings. Transient Turrialba He detections (up to 20ppmv) were obtained with a small (~10kg) airborne mass spectrometer on a light aircraft—a UAV version (~3kg) will deploy there soon on the UCR DELTA 500. Thus, these platforms, though small (most payloads de Costa Rica, the NASA Airborne Science and Earth Surface & Interior Programs, the Dirección General de Aeronáutica Civil de Costa Rica, and FH Düsseldorf for their support.

    Full Text Available O objetivo neste artigo é verificar a importância do tamanho da empresa no desenvolvimento de competências. O pressuposto central é que multinacionais brasileiras de pequeno porte precisam desenvolver mais competências organizacionais quando comparadas com multinacionais de grande porte. Os dados decorrem de um survey que obteve a resposta de 92 empresas brasileiras, a saber: 48 multinacionais de grande porte e 44 multinacionais de pequeno porte. Técnicas estatísticas de análise fatorial e modelagem linear generalizada são usadas para verificar a influência do tamanho da multinacional no desenvolvimento de competências. O resultado mostra que multinacionais brasileiras de pequeno porte desenvolvem mais competências no exterior quando comparadas com as grandes empresas. Portanto, ao menos para as multinacionais brasileiras, como representantes das empresas de países emergentes, o tamanho é um aspecto central para explicar as estratégias de desenvolvimento de competências no exterior.

    Full Text Available Cardiology has been and is a very significant fraction of the Brazilian contribution to science. In older days, the most significant part of this work was directed to foreign periodicals, but the quasi-simultaneous emergence of SciELO and PUBMED has ordained a redirection of much of this work to Brazilian periodicals. We here survey some of this more recent contribution for the benefit of readers of Revista Brasileira de Cirurgia Cardiovascular. This is offered as an update. Articles on the general themes of Cardiology and Pneumology published by four ISI Indexed Brazilian journals not specializing in cardiology are re-visited, after a search through 10 journals.A Cardiologia foi, e continua sendo, responsável por uma fracção muito significativa da contribuição brasileira para a ciência.

    Herrera, Alfonso Herrera

    1996-07-01

    The electric power system management in Costa Rica is analyzed. The possibility of substitution of LPG (Liquefied Petroleum Gas) for electric power, in home cooking, are identified as one of the most important program in order to reduce increasing load peak and energy requirements in electric power system of Costa Rica. The sustain ability of the substitution program stands on the current process of electric power supply. The primary power sources used in generating electric power in rush hours are oil-based; this process is less efficient than directly using LPG for home cooking. Large scale substitution with LPG in home cooking will reduce increasing electric power demand in peak hours, reducing subsidized electricity sales, with better use of combustibles presently imported, improving the country commercial balance and preventing or postponing electric power system expansion investments. Three different perspectives have been considered in evaluating economical effectiveness in substituting power sources: user, utility and society perspectives. Due to subsidized electric power prices, residential users do not enough interest in substituting of LPG for power source; unless LPG cookers are also subsidized. However, positive results for the distribution utility are enough in order to offer these kind of incentives. Explicit treatment of these kind of programs, including the efficiency increment as an available resource for electric power utilities in Costa Rica, will avoid the implantation of most of combustion plants now planned in current National Electric Power Plant expansion program.

    Full Text Available O artigo apresenta os resultados de uma pesquisa sobre os efeitos da cobertura da imprensa no voto nas eleições presidenciais brasileiras de 2002 e 2006. Argumenta-se que ela foi um fator importante em ambos os pleitos. A variável dependente é formada pelas séries históricas de intenção de voto dos principais candidatos: Lula (Partido dos Trabalhadores, Serra (Partido da Social Democracia Brasileira, Garotinho (Partido Socialista Brasileiro e Ciro (Partido Popular Socialista em 2002, e Lula, Alckmin (Partido da Social Democracia Brasileira, Heloísa Helena (Partido Socialismo e Liberdade e Cristovam Buarque (Partido Democrático Trabalhista em 2006. A principal variável explicativa é a cobertura eleitoral de quatro grandes jornais do país: Folha de S. Paulo, O Estado de S. Paulo, O Globo e Jornal do Brasil. Completam o modelo as seguintes variáveis de controle: propaganda partidária dos candidatos, o Horário Político Gratuito Eleitoral no 1º e 2º turnos, os debates presidenciais e o índice de popularidade presidencial. Os modelos foram estimados via MQO. Os resultados dos testes indicam que, em 2002, a cobertura da imprensa de Lula e Ciro Gomes foi uma das responsáveis pela variação observada nas suas respectivas intenções de voto. Em 2006, a dinâmica foi um pouco mais complexa. Apenas as intenções de voto em Heloísa Helena foram afetadas por sua própria cobertura. A princípio, é surpreendente que a cobertura extremamente negativa de Lula não tenha lhe custado votos. Mas ela teve um impacto indireto, e importante, para Alckmin e Cristovam Buarque. Como esse impacto foi maior durante o escândalo do dossiê tucano, podese afirmar que a cobertura da imprensa contribuiu decisivamente para a ocorrência do 2º turno na última eleição presidencial. Esses resultados mantêm-se mesmo quando se analisam os votos de eleitores de grupos de escolaridade distintos, um controle para os diferentes níveis de exposição aos

    Full Text Available RESUMO O tempo de deslocamento de casa ao trabalho tem se elevado substancialmente nas regiões metropolitanas brasileiras durante a última década. Esse fenômeno tem implicações fortes sobre o bem-estar dos indivíduos, porém as consequências desse problema não se distribuem uniformemente entre a população. O presente trabalho visa contribuir para o debate sobre a questão da mobilidade urbana nas metrópoles brasileiras analisando a evolução do tempo de deslocamento entre 1992 e 2013 e suas diferenças de acordo com características do trabalhador, como sexo, cor e renda per capita , e do posto de trabalho. Verifica-se que o aumento do tempo médio de deslocamento ocorreu a partir de 2003, caracterizando uma questão particularmente importante para as metrópoles brasileiras no terceiro milênio. Os trabalhadores com maiores tempos médios de deslocamento residem nas regiões metropolitanas do Rio de Janeiro e de São Paulo. Entretanto, as maiores taxas de crescimento ocorreram nas metrópoles do Pará, Salvador e Recife, sugerindo a necessidade de melhor direcionamento e planejamento de políticas públicas na mobilidade urbana. Considerando as diferenças socioeconômicas, destaca-se que os mais pobres e os mais ricos (extremos da distribuição de renda tendem a apresentar tempos de deslocamento menores do que os trabalhadores de famílias de renda média. Esse padrão se mantém ao longo do tempo, com aumento do tempo médio de deslocamento entre os mais pobres, mostrando uma face da desigualdade. Porém, o maior aumento ocorreu entre os mais ricos, colocando a questão da mobilidade urbana para além dos problemas de exclusão social.

Nos três casos, a proeminência dos argumentos que sustentam os pontos de vista das finanças, vistos como positivos no quadro sugerido pela cronologia, são contrapostos às dificuldades da sua crítica, que é associada às suas polaridades negativas.The article argues for the existence of a financial mode of domination in Brazilian society at the start of the 21st century. In support of this claim, it provides a chronology of the recent transformations in Brazilian economic culture and draws evidence from various spheres: (i on the success of the rhetoric justifying the continuance of high interest rates in the country, supposedly a response to the disorganization of Brazilian society; (ii on the propagation of corporate governance, increasingly advocated as the ideal method for managing and evaluating 'modern' organizations; (iii on the logic adopted by the explicit critique of financial domination, which attempts to personify the phenomenon in the form of 'exemplary' individuals. In all three cases, the pre-eminence of the arguments sustaining the financial viewpoint - seen as positive within the ideological framework of the proposed chronology - are contrasted with the difficulties faced by its critique, associated with its negative

RESULTADOS: Características peculiares da cultura da população surda apontaram a necessidade de adaptações na metodologia de aplicação de grupos focais quando compostos por pessoas surdas. As convenções ortográficas da escrita das línguas sinalizadas não estão consolidadas, o que trouxe dificuldades em registrar graficamente as etapas de tradução. As estruturas linguísticas que causaram maiores problemas de tradução foram as que incluíram expressões idiomáticas do português, muitas sem conceitos equivalentes entre o português e a Libras. Foi possível construir um software do WHOQOL-BREF e WHOQOL-DIS em Libras. CONCLUSÕES: O WHOQOL-BREF e o WHOQOL-DIS em Libras possibilitarão que os surdos se expressem autonomamente quanto a sua qualidade de vida, o que permitirá investigar com maior precisão essas questões.

    2003-01-01

    Costa Rica lies at the intersection of the Cocos and Caribbean plates in Central America. It has mountain ranges with many active volcanoes along its territory. Its soils are predominantly of volcanic origin. Natural radiation measurements utilising environmental CaF 2 :Dy thermoluminescence dosimeters were used for the first time in Costa Rica by the Dosimetry Section of the Atomic, Nuclear and Molecular Sciences Research Center of the University of Costa Rica. Seven hundred outdoor measurements were obtained in a 3.5-year period at eight different sites throughout the country. One hundred and seventy-four indoor readings were also collected at four sites for a 2-year period. Population-weighted averages give 82 nGy h -1 for outdoors and 130 nGy h -1 for indoors. The values lie on the upper range of worldwide reported values due to reported soil characteristics rich in uranium and potassium. A preliminary population-weighted value of 0.74 mSv/year for the effective dose is calculated for natural terrestrial gamma radiation in Costa Rica

    Maintained dedication to primary care has fostered a public health delivery system with exceptional outcomes in Costa Rica. For more than a decade, management commitments have been part of Costa Rican health reform. We assessed the effect of the Costa Rican management commitments on access and quality of care and on compliance with their intended objectives. We constructed seven hypotheses on opinions of primary care providers. Through a mixed qualitative and quantitative approach, we tested these hypotheses and interpreted the research findings. Management commitments consume an excessive proportion of consultation time, inflate recordkeeping, reduce comprehensiveness in primary care consultations, and induce a disproportionate consumption of hospital emergency services. Their formulation relies on norms in need of optimization, their control on unreliable sources. They also affect professionalism. In Costa Rica, management commitments negatively affect access and quality of care and pose a threat to the public service delivery system. The failures of this pay-for-performance-like initiative in an otherwise well-performing health system cast doubts on the appropriateness of pay-for-performance for health systems strengthening in less advanced environments.

    Blahnik, R. J.; Holzenthal, R. W.

    2005-05-01

    Protoptila is the most diverse of the genera in the subfamily Protoptilinae of the family Glossosomatidae, currently with 80 species, but many more from the Neotropics awaiting description. Fourteen species occur in the United States, only one of which is also known to occur in Mexico. This compares to 38 species and one subspecies (or about half of the total for the genus) currently known from Central America, mostly described in papers by Mosely and Flint. Although the majority of these, or some 27 species, occur in Mexico, this probably more closely reflects the historical intensity of collecting rather than the real diversity by region. In Costa Rica, 11 species are currently known, 8 of which are restricted in distribution to Costa Rica, or Costa Rica and Panama, and only 3 with distributions extending to Mexico. We are describing an additional 8 species from Costa Rica, bringing to 19 the number of species now known from the country. This represents an incredible diversity for such a small country and also a very high level of implied endemism, even considering the likelihood that some of the species will be found to have wider distributions.

    Directory of Open Access Journals (Sweden)

    Julia A. Flagg

    2018-01-01

    Full Text Available Costa Rica has pledged to become the first nation to become carbon neutral. This event raises the important question of how to understand this contemporary form of climate politics, given that Costa Rica has made an almost negligible contribution to the problem of global climate change. To understand this pledge, a case study spanning about 200 years situates the pledge within the country’s unique historical profile. An analysis of interview data, archival research, and secondary data reveals that the pledge is the latest instance in Costa Rica’s unusual political tradition. This political tradition dates back to the area’s experience as a Spanish colony and as a newly independent nation. Several events, including the abolition of the army, the work on green development, and being awarded a Nobel Peace Prize were all foundational in forming Costa Rica’s tradition as a place that leads by example and stands for peace and protection of nature. The carbon neutral pledge extends the political tradition that has been established through these earlier events. This case highlights the importance of understanding contemporary environmental politics through an analysis of long-term, historical data.

El estudio aquí reportado analizó las condiciones socio-económicas de tres comunidades vecinas al Parque Nacional Braulio Carrillo (PNBC, en Costa Rica, identificó los problemas ambientales de los residentes de las mismas que se podrían agravar por causa del desarrollo turístico y determinó cómo y bajo qué condiciones los habitantes de la zona querían que se realizara el desarrollo turístico de las comunidades. Se entrevistaron 123 de un total de un total de 155 casas en las tres comunidades, y se utilizó una combinación de componentes principales y análisis factorial para analizar los datos. Los resultados indican que los vecinos entrevistados desean que el desarrollo turístico sea hecho sosteniblemente, y que además, se planifique, se establezcan requisitos claros, que la comunidad sea periódicamente informada, que sus lideres comunales participen activamente en el proceso, se establezcan programas para ayudar al desarrollo de micro-empresas eco-turísticas, y que se les brinde asistencia técnica y capacite en el desarrollo de proyectos eco-turísticos. Los problemas eventuales asociados a la calidad ambiental que habría que prestarles atención preferente son: ruido y tráfico excesivo, manejo de aguas negras y deforestación. El desarrollo turístico sostenible relacionado con el primer componente implicaría que este es un requisito básico de la calidad ambiental, la conservación y el uso sostenible del patrimonio histórico.

Contrairement à la côte caribéenne du Mexique qui a souffert du développement du tourisme de masse à Cancun et le long de la Riviera Maya, la Costa Maya s'est orientée vers un développement durable avec notamment une faible densité de construction et le développement de l'écotourisme.Le développement s'est concentré autour de Puerto Costa Maya où un terminal de croisière a été construit en 2001. La station balnéaire (balneario de Majahual est devenue dépendante des 10-12 bateaux de touristes qui débarquaient chaque semaine. En dépit d'importants plans de développement, les plages reculées de la Costa Maya accueillaient tout au plus des écotouristes aisés et du tourisme lié à la plongée sous-marine.Le cyclone Dean, de catégorie 5, a dévasté le paysage en août 2007 et le rétablissement économique n'a pu être entamé que fin 2008, après la réouverture du terminal de croisière et la reconstruction de Majahual. Fin 2009, le trafic de croisière n'a pas retrouvé son niveau d'avant Dean et la récession mondiale couplée avec la grippe porcine et les violences liées à la drogue ont fait diminuer le tourisme en provenance des Etats-Unis.

    The costa is a prominent striated fibre that is found in protozoa of the Trichomonadidae family that present an undulating membrane. It is composed primarily of proteins that have not yet been explored. In this study, we used cell fractionation to obtain a highly enriched costa fraction whose structure and composition was further analysed by electron microscopy and mass spectrometry. Electron microscopy of negatively stained samples revealed that the costa, which is a periodic structure with alternating electron-dense and electron-lucent bands, displays three distinct regions, named the head, neck and body. Fourier transform analysis showed that the electron-lucent bands present sub-bands with a regular pattern. An analysis of the costa fraction via one- and two-dimensional electrophoresis and liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) allowed the identification of 54 hypothetical proteins. Fourteen of those proteins were considered to be major components of the fraction. The costa of T. foetus is a complex and organised cytoskeleton structure made of a large number of proteins which is assembled into filamentous structures. Some of these proteins exhibit uncharacterised domains and no function related according to gene ontology, suggesting that the costa structure may be formed by a new class of proteins that differ from those previously described in other organisms. Seven of these proteins contain prefoldin domains displaying coiled-coil regions. This propriety is shared with proteins of the striated fibres of other protozoan as well as in intermediate filaments. Our observations suggest the presence of a new class of the cytoskeleton filaments in T. foetus. We believe that our data could auxiliate in determining the specific locations of these proteins in the distinct regions that compose the costa, as well as to define the functional roles of each component. Therefore, our study will help in the better understanding of the

    The purpose of this study was to explore the experiences of classroom teachers who participated in a science-focused study abroad during their time as a preservice teacher and to explore how they are using their study abroad experiences in science curriculum planning and in classroom instruction. This study is guided by two research questions: 1) what are the study abroad experiences that have influenced classroom teachers; and, 2) how do classroom teachers incorporate study abroad experiences into science curriculum planning and instruction in the classroom? Participants were two in-service science teachers from schools located in the Southwestern United States. The participants were enrolled in the course, Environmental Science and Multicultural Experience for K-8 Teachers offered through the Department of Educational Leadership, Curriculum and Instruction during their time as preservice teachers. The course included a two-week study abroad component in Costa Rica. Participants spent their mornings observing a monolingual, Spanish-speaking elementary classroom followed by a faculty-led multicultural seminar. Afternoons during the study abroad experience were dedicated to field science activities such as quantifying plant and animal biodiversity, constructing elevation profiles, determining nutrient storage in soil, and calculating river velocity. Throughout the course students participated in science-focused excursions. A cross case study design was used to answer the two research questions guiding this dissertation study. Data collection included participant-created concept maps of the science experiences during the study abroad experience, in-depth interviews detailing the study abroad experience and classroom instruction, and participant reflective journal entries. Cross-caseanalysis was employed to explore the uniqueness of each participant's experience and commonalities between the cases. Trustworthiness was established by utilizing multiple sources of data

    The relationship of education, psychiatric diagnoses, and use of psychotropic medication has been explored in the United States, but little is known about this relationship in poorer countries, despite the high burden of mental illness in these countries. This study estimated educational gradients in diagnosis and psychotropic drug use in the United States and Costa Rica, a middle-income country with universal health insurance. Analyses were conducted by using data of older adults (≥60) from the 2005 U.S. Medical Expenditure Panel Survey (N=4,788) and the 2005 Costa Rican Longevity and Healthy Aging Study (N=2,827). Logistic regressions examined the effect of education level (low, medium, or high) and urban residence on the rates of self-reported mental health diagnoses, screening diagnosis, and psychotropic medication use with and without an associated psychiatric diagnosis. Rates of self-reported diagnoses were lower in the United States (12%) than in Costa Rica (20%), possibly reflecting differences in survey wording. In both countries, the odds of having depression were significantly lower among persons with high education. In Costa Rica, use of psychotropic medication among persons with self-reported diagnoses increased by education level. The educational gradients in medication use were different in the United States and Costa Rica, and stigma and access to care in these countries may play an important role in these differences, although type of insurance did not affect educational gradients in the United States. These analyses increase the evidence of the role of education in use of the health care system.

    Costa Rica has a very high seismicity rate and geological processes are part of everyday life. Traditionally, information about these processes has been provided by conventional mass media (television and radio). However, due to the new trends in information flow a new approach towards Science Education is necessary for transmitting knowledge from scientific research for the general public in Costa Rica. Since 1973, the National Seismological Network of Costa Rica (RSN: UCR-ICE) studies the seismicity and volcanic activity in the country. In this study, we describe the different channels to report earthquake information that the RSN is currently using: email, social networks, and a website, as well as the development of a smartphone application. Since the RSN started actively participating in Social Networks, an increase in awareness in the general public has been noticed particularly regarding felt earthquakes. Based on this trend, we have focused on enhancing public outreach through Social Media. We analyze the demographics and geographic distribution of the RSN Facebook Page, the growth of followers, and the significance of their feedback for reporting intensity data. We observe that certain regions of the country have more Facebook activity, although those regions are not the most populated nor have a high Internet connectivity index. We interpret this pattern as the result of a higher awareness to geological hazards in those specific areas. We noticed that the growth of RSN users on Facebook has a strong correlation with the seismic events as opposed to Twitter that displays a steady growth with no clear correlations with specific seismic events. We see the Social Networks as opportunities to engage non-science audiences and encourage the population to participate in reporting seismic observations, thus providing intensity data. With the increasing access to Internet from mobile phones in Costa Rica, we see this approach to science education as an opportunity

    Costa Rica has one of the greatest percentages (26%) of protected land in the world. The National Protected Areas System (NPAS) of Costa Rica was established in 1976 and currently includes >190 protected areas within seven different protection categories. The effectiveness of the NPAS to represent species, populations, and areas with high species richness has not been properly evaluated. Such evaluations are fundamental to understand what is necessary to strengthen the NPAS and better protect biodiversity. We present a novel assessment of NPAS effectiveness in protecting mammal species. We compiled the geographical ranges of all terrestrial Costa Rican mammals then determined species lists for all protected areas and the estimated proportion of each species’ geographic range protected. We also classified mammal species according to their conservation status using the IUCN Red List of Threatened Species. We found almost complete representation of mammal species (98.5%) in protected areas, but low relative coverage (28.3% on average) of their geographic ranges in Costa Rica and 25% of the species were classified as underprotected according to a priori representation targets. Interestingly, many species-rich areas are not protected, and at least 43% of cells covering the entire country are not included in protected areas. Though protected areas in Costa Rica represent species richness well, strategic planning for future protected areas to improve species complementarity and range protection is necessary. Our results can help to define sites where new protected areas can have a greater impact on mammal conservation, both in terms of species richness and range protection. PMID:25970293

    Describe the relationship between the attitude towards violence against women (VAW) of professionals of the health of primary care with variables such professional satisfaction, workload, orientation of professional practice, knowledge, training and use of network in Catalonia and Costa Rica. Cross-exploratory and comparative study. Primary care in Barcelona and nearby counties and the Greater Metropolitan Area (GAM) of Costa Rica. 235 primary health professionals of Medicine, Nursing, Psychology and Social Work. Questionnaire with eight sections about attitudes, professional satisfaction, and orientation of professional practice, workload, knowledge, training and use of network. Three types of analysis were carried out: a descriptive one by country; a bivariate analysis; and a multivariable linear regression model. Primary Health Professionals attitudes towards VAW health were similar in both contexts (Catalonia: 3.90 IC 95% 3.84-3.96; Costa Rica: 4.03 IC 95% 3.94-4.13). The variables associated with attitudes towards VAW were: Use of network resources (B=0.20, 95% CI -0.14-0.25, P=<.001), Training (B=0.10, 95% CI 0.04 to 0.17, P=<0.001), and country, Costa Rica (B=0.16, 95% CI 0.06 to 0.25, P=<0.001). There was no interaction between the country and the other variables, suggesting that the association between the variables and the attitude is similar in both countries. The results suggest that increased use of network resources and training are related to a positive attitude towards VWA in primary health professionals, both in Catalonia and Costa Rica.

    Full Text Available En este documento se estima una medida de la incertidumbre inflacionaria. Un modelo de inflación señala incertidumbre cuando los errores de pronóstico son heteroscedásticos. Por medio de la especificación de una ecuación GARCH (Generalized Autoregressive Conditional Heteroscedasticity, para la varianza del término de error de un modelo de inflación, es posible estimar una proxy de incertidumbre inflacionaria. La estimación simultánea del modelo de inflación y de la ecuación GARCH, produce un nuevo modelo de inflación en el cual los errores de pronóstico son homocedásticos. Existe consenso en la literatura económica en que hay una correlación positiva entre incertidumbre inflacionaria y la magnitud de la tasa de inflación, lo cual, como lo señaló Friedman (1977, representa uno de los costos asociados con la persistencia inflacionaria. Esto es porque tal incertidumbre dificulta la toma de decisiones óptimas por parte de los agentes económicos.La evidencia empírica, para el periodo 1954:01-2002:08, apoya la hipótesis de que para el caso de Costa Rica mientras mayor es la inflación mayor es la incertidumbre respecto a esta variable. En los últimos siete años (1997-2002 la incertidumbre presenta la variación media más baja de todo el periodo. Además, se identifica un efecto asimétrico de la inflación sobre la incertidumbre inflacionaria, es decir, la incertidumbre inflacionaria tiende a incrementarse más para el siguiente periodo cuando la inflación pronosticada está por debajo de la inflación actual, que cuando la inflación pronosticada está por arriba de la tasa observada de inflación. Estos resultados tienen una clara implicación para la política monetaria. Para minimizar la dificultad que la inflación causa en la toma óptima de decisiones de los agentes económicos es necesario perseguir no solamente un nivel bajo de inflación sino que también sea estable.AbstractThis paper estimates a measure of

    Full Text Available We visited 51 lakes in Costa Rica as part of a broad-based survey to document their physical and chemical characteristics and how these relate to the mode of formation and geographical distribution of the lakes. The four oxbow lakes were low in elevation and tended to be turbid, high in conductivity and CO2 , but low in dissolved O2 ; one of these, L. Gandoca, had a hypolimnion essentially composed of sea water. These were similar to the four wetland lakes, but the latter instead had low conductivities and pH, and turbidity was often due to tannins rather than suspended sediments. The thirteen artificial lakes formed a very heterogenous group, whose features varied depending on local factors. The thirteen lakes dammed by landslides, lava flows, or lahars occurred in areas with steep slopes, and were more likely to be stratified than most other types of lakes. The eight lakes that occupy volcanic craters tended to be deep, stratified, clear, and cool; two of these, L. Hule and L. Río Cuarto, appeared to be oligomictic (tending toward meromictic. The nine glacial lakes, all located above 3440 m elevation near Cerro Chirripó, were clear, cold, dilute, and are probably polymictic. Cluster analysis resulted in three significant groups of lakes. Cluster 1 included four calcium-rich lakes (average 48 mg l-1, Cluster 2 included fourteen lakes with more Si than Ca+2 and higher Cl- than the other clusters, and Cluster 3 included the remaining thirty-three lakes that were generally less concentrated. Each cluster included lakes of various origins located in different geographical regions; these data indicate that, apart from the high-altitude glacial lakes and lakes in the Miravalles area, similarity in lake chemistry is independent of lake distribution.Se visitaron 51 lagos en Costa Rica como parte de un sondeo de lagos más amplio, con el fin de documentar sus carácteristicas físicas y químicas y las relaciones entre estas carácteristicas y el modo

    The inquiry of this study is the beliefs related to the nursing professional in the first decades of this activity in Brazil. The investigation presupposes that some of these beliefs are still current. The objective is to point out the beliefs expressed by Revista Brasileira de Enfermagem (Brazilian Journal of Nursing) in 33 articles, during the period between 1932 (when the journal was created) and 1954. Five notions of the nursing professional were identified through the analyses of the symbology presented on the cover of the periodical--Egyptian mythology; ideal, science and art, inscribed in a triangle. The categories established for nurses were: self-forgetful, heroine, socially committed, mercenary and bad angel. Finally, the study proposes an interpretation to the ideas presented in the triangle.

    Full Text Available In this study, we reflect upon the importance of scientific journals for the circulation and the legitimation of scientific knowledge. For this purpose, we gathered as object the Revista Brasileira de Filologia, a representative journal that circulated between the 1950s and early 1960s under the Brazilian national context. In view of this journal and the socio-historical context of its circulation, we analyzed how this discursive materiality has contributed to the legitimacy of certain areas of knowledge, such as Philology, Linguistics and Dialectology. Therefore, our main goal is to understand how this journal influences and contributes to the establishment and constitution of linguistic knowledge both in the national context and in southern Brazil. The development of this study is affiliated to the theoretical assumptions of the History of Linguistic Ideas and Pêcheux’s Discourse Analysis, as both are developed in Brazil.

    Revista Brasileira de Enfermagem-REBEn (Brazilian Journal of Nursing) is now 70 years old. It was created in 1932, and was initially called Anais de Enfermagem. Its main purpose was to be a communication link among Brazilian professionals of nursing. REBEn, which is directly linked to ABEn (Brazilian Association of Nursing), also has as its objective the publicizing of scientific production in different fields of knowledge which can be of interest for the nursing profession. The journal went through many difficulties before achieving the current status of most important publishing in the field of nursing in Brazil. The periodical was developed along many generations and has now achieved intellectual maturity which guaranteed its inclusion in the international indexation of scientific periodicals.

    Alberto Augusto Eichman Jakob

    Full Text Available Resumo O objetivo principal deste artigo é analisar a migração na Amazônia brasileira. São analisados os migrantes provenientes de outros países, em especial os transfronteiriços, assim como os migrantes brasileiros. A ideia é observar também qual o impacto destes migrantes na localidade de destino na Amazônia e o papel das cidades fronteiriças neste processo. Serão estas cidades apenas de passagem para a entrada no país ou possuem atrativos suficientes para que uma parte dos migrantes fique nelas? Estariam elas prontas para receber um volume substancial de migrantes? Estes migrantes vêm diretamente de seus países ou possuem experiência prévia em outras Unidades da Federação brasileiras? Para tentar esclarecer isto, são utilizados dados do Censo Demográfico de 2010 e da Contagem Populacional de 2007 para se analisar as características dos migrantes segundo sua origem, assim como seu local escolhido de destino. A partir das análises deste trabalho, percebe-se que o perfil da migração segundo a origem é diferente, e também a escolha do local de destino, possivelmente em função das redes sociais, que têm um papel importante neste processo de atração de migrantes em determinadas áreas.

    Colonially-nesting birds often nest in coastal areas, along rivers, or near other bodies of water that also are potentially polluted from industrial, agricultural or urban development. The levels of heavy metals and selenium were examined in the feathers of young wood storks Mycteria americana nesting in Northeastern Florida and from adult and young storks nesting on the Tempisque River on the west coast of Costa Rica. There were no significant yearly differences among the chicks from Costa Rica. Concentration of mercury, cadmium, and lead were significantly higher in the chicks from Florida compared to those from Costa Rica. Adult wood storks at Costa Rica had significantly higher levels of lead, cadmium, selenium, and manganese than young from the same colony.

    Full Text Available Food habits of 15 species of frugivorous bats were studied at La Selva Biological Station, Costa Rica. Eight hundred and fifty-four (854 fecal samples and 169 samples from fruit parts and seeds discarded by bats beneath feeding roosts were analyzed. During eight months of study, 47 fruit species consumed by bats were identified. Five plant genera (Cecropia, Ficus, Piper, Solanum, and Vismia constituted 85% of all plants found in fecal samples. Feeding niche breadth differed significantly among the six most common species of frugivorous bats (Artibeus jamaicensis, Carollia sowelli, C. castanea, C. perspicillata, Dermanura sp., and Glossophaga commissarisi. All species, except for Dermanura sp., showed a diet dominated by one or two plant species. This suggests a pattern of resource partitioning at a generic level, in which Carollia consumed mainly Piper, Artibeus consumed Ficus and Cecropia, and Glossophaga consumed Vismia. Cluster analysis revealed higher values of food niche overlap in congeneric species than among species of different genera. Results show that if food is a limiting factor, mechanisms other than trophic selection must reduce interspecific interference or competition for food in this frugivorous bat guild. Rev. Biol.

    Full Text Available La distrofia miotónica tipo1 (DM1 y el síndrome del cromosoma X frágil (FRAXA son dos enfermedades hereditarias relativamente comunes. Ambas constituyen ejemplos de un nuevo tipo de mecanismo mutacional, llamado mutaciones inestables o dinámicas, expansión de tripletas, o amplificación del ADN. La DM1 se considera como la distrofia muscular más frecuente en los adultos y FRAXA es la principal causa de retardo mental hereditario. Este trabajo presenta resultados actualizados de un estudio prospectivo no aleatorio en pacientes clínicamente afectados, que se realiza con el objetivo de confirmar el diagnóstico con técnicas moleculares (Hibridación de Southern y reacción en cadena de la polimerasa, PCR, y llevar a cabo el tamizaje en cascada del resto de la familia para ofrecerles consejo genético adecuado. Se confirmó el diagnóstico clínico inicial en la mayoría de los casos de distrofia miotónica, pero en los casos con retardo mental, más de la mitad de los análisis resultaron negativos para la amplificación en el gen FMR1, específica de FRAXA. La razón principal para esto podría ser el cuadro clínico muy sutil que muestran los niños afectados antes de la pubertad. Los únicos métodos disponibles para prevenir estas discapacidades por el momento son, el tamizaje en cascada, el consejo genético y el aborto selectivo. De los cuales, el último no se puede llevar a cabo según las leyes vigentes en Costa Rica.Myotonic dystrophy and fragile X syndrome are two genetically determined relatively common disabilities.

    Full Text Available Utilizando datos del Registro Nacional de defunciones de los años 1996-2005 se calcularon las tasas de mortalidad estandarizadas por edad para personas nacidas en Nicaragua versus personas nacidas en Costa Rica. 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. El riesgo relativo de causas de mortalidad de origen de tipo exógeno entre los inmigrantes nicaragüenses fue más grande entre los grupos de edad joven en áreas de baja densidad de inmigrantes nicaragüenses. La población nacida en Nicaragua residiendo en Costa Rica tiene un riesgo reducido de mortalidad por causas generales versus las personas nacidas en Costa Rica en los años entre 1996-2005. Esto se debe a una mortalidad por enfermedad reducida, la cual es bastante marcada. El homicidio es un una razón de mayor mortalidad entre los inmigrantes nacidos en Nicaragua versus los nativos costarricenses. Hay una gran necesidad de llevar acabo investigaciones adicionales sobre el rol de la migración, estatus socioeconómico y comportamientos entorno a la salud para poder explicar más a fondo los patrones de mortalidad diferenciales entre los inmigrantes nicarag

Además, se caracterizó a ese segmento poblacional a partir de diferentes variables: sexo, edad, estado civil y distribución geográfica. También se abordaron otros aspectos como fueron: alfabetismo, nivel de educación, ocupación, jefatura de hogar y vivienda. Entre los hallazgos más destacables se encuentra la permanencia, en los registros censales del siglo XX, de un concepto de discapacidad basado en la deficiencia, lo que definió los criterios de clasificación para esa población en esas fuentes. Asimismo se constató, por una parte, la asociación entre discapacidad e inequidad en esa centuria y, por la otra, la fragilidad de los vínculos de parentesco en ese grupo poblacional con respecto al conjunto de hogares de Costa Rica a fines de ese siglo. Las fuentes empleadas en esta investigación fueron los censos de población de Costa Rica del siglo XX. En el procedimiento con los datos, se llevó a cabo un análisis descriptivo de distribución de frecuencias.This research discloses the classification criteria used to define the population with disability in the twentieth century census records in Costa Rica and therefore gives an approximation of the conceptual formulations needed to refer to the examined group.

    Full Text Available From 1993 to 1997, we observed Scarlet Macaw (Ara macao feeding behavior in Central Pacific Costa Rica. Feeding data acquired in this study were not collected systematically, but opportunistically whenever macaws were observed feeding. To supplement feeding observations, we conducted interviews with local residents. Scarlet Macaws fed on seeds, fruits, leaves, flowers and/or bark of 43 plant species. Various plant parts eaten by macaws from several tree species contain secondary compounds toxic to humans, and additional species included in their diet are nonnative, introduced for agricultural purposes. Important macaw feeding tree species are Ceiba pentandra, Schizolobium parahybum, and Hura crepitans; these species are also crucial to this macaw population because of nest cavities they provide. The results of this study contribute to the conservation of Scarlet Macaws in Central Pacific Costa Rica through promoting protection of individual trees, and through local elementary school reforestation programs focusing on tree species that macaws use for feeding and/or nesting. Scarlet Macaw conservation is extremely important, as numerous population pressures have caused significant declines in macaw numbers in Costa Rica. Rev. Biol. Trop. 54 (3: 919-926.

  1. Ambient Tremor, But No Triggered Tremor at the Northern Costa Rica Subduction Zone

    Swiecki, Z.; Schwartz, S. Y.

    2010-12-01

    Non-volcanic tremor (NVT) has been found to be triggered during the passage of surface waves from various teleseismic events in locations around the world including Cascadia, Southwest Japan, Taiwan, and California. In this study we examine the northern Costa Rica subduction zone for evidence of triggered tremor. The Nicoya Peninsula segment of the northern Costa Rica margin experiences both slow-slip and tremor and is thus a prime candidate for triggered tremor observations. Eleven teleseismic events with magnitudes (Mw) greater than 8 occurring between 2006 and 2010 were examined using data from both broadband and short period sensors deployed on the Nicoya Peninsula, Costa Rica. Waveforms from several large regional events were also considered. The largest teleseismic and regional events (27 February 2010 Chile, Mw 8.8 and 28 May 2009 Honduras, Mw 7.3) induced peak ground velocities (PGV) at the NIcoya stations of ~2 and 6 mm/s, respectively; larger than PGVs in other locations that have triggered tremor. Many of the earthquakes examined occurred during small episodes of background ambient tremor. In spite of this, no triggered tremor was observed during the passage of seismic waves from any event. This is significant because other studies have demonstrated that NVT is not triggered everywhere by all events above some threshold magnitude, indicating that unique conditions are required for its occurrence. The lack of triggered tremor at the Costa Rica margin can help to better quantify the requisite conditions and triggering mechanisms. An inherent difference between the Costa Rica margin and the other subduction zones where triggered tremor exists is its erosional rather than accretionary nature. Its relatively low sediment supply likely results in a drier, lower pore fluid pressure, stronger and less compliant thrust interface that is less receptive to triggering tremor from external stresses generated by teleseismic or strong local earthquakes.

No entanto, as representações dos gays criadas a partir do discurso jornalístico podem determinar e/ou intensificar o processo de marginalização dos homossexuais na sociedade. A partir da análise da reportagem sobre casais gays que adotaram crianças, veiculada no programa Globo Repórter da Rede Globo, buscamos contribuir neste artigo para a discussão sobre a construção da homossexualidade pela Imprensa brasileira.

    2017-04-01

    Full Text Available Available data shows an increase in international migration departing from Costa Rica, mainly to the United States. Based on the data obtained from two surveys conducted with potential emigrants and families with members living abroad, this paper is aimed at understanding their reasons for emigrating. In addition, some socio-economic impacts in four suburbs with high rates of emigration are identified. From a political economy approach, the most appropriate framework to better understand these emigration cases is discussed.  Moreover, the transformation of the employment and productive matrix followed by Costa Rica during the last three decades, as well as the country’s form of insertion into the international economy are two structural factors strongly linked to the emigration of the subjects studied in this paper.

    Costa Rica has shown how a small developing country can grab the bull of environmental degradation by the horns, and reverse one of the highest deforestation rates in Latin America to become the poster child of environment success. Key to its achievement has been the country's payments for environmental services (PES) programme, which began in 1997 and which many countries are now looking to learn from, especially as water markets and schemes to reward forest conservation and reduced deforestation (REDD+) grow. Within Costa Rica too, there is a need to first reflect on how the contexts for, and challenges facing, PES have changed; and continue building a robust programme that can ensure the coming decade is as successful as the past one.

    Full Text Available The MSME Observatory has been studying MSMEs in Costa Rica. Its findings show that for every formal enterprise, there are 2.4 semi-formal ones. The latter refers to those enterprises that have already started the formalization process with the corresponding municipality but that still do not have all the formalization requirements.Owing to the importance of the semi-formal sector in the economic activity of Costa Rica, this study analyzed this business park and the role of municipal management concerning MSMEs, calculated the correlation among semi-formality, competitiveness, and development, and finally, proposed a cluster design to deal with the state of affairs. It should be noted that this type of analysis has never been undertaken in the country.

    Full Text Available This essay is part of the products from the Reconstruction of Knowledge project –attached to the Division of Rural Education of the National University of Costa Rica. This work seeks to create a thoughtful look regarding the existing indigenous education model in Costa Rica in general– and particularly in Talamanca. A methodology based on collaborative action research with indigenous teachers in the region of Talamanca Bribri and Talamanca Cabécar was used as a starting point. This methodology combined focus group discussions and individual interviews with a qualitative approach that allowed generating a series of critical impressions about the education system where they work. All this will lead to a summary of insights and specific recommendations that would strengthen the educational system for the indigenous population of Talamanca and would allow moving towards a true model of Intercultural Bilingual Education.

    Amphibians, turtles, mice and birds from a protected Costa Rican wildland were contaminated with organochlorine pesticides and metabolites. - Amphibians, turtles, birds (mostly passerines) and mice collected from a conservation area in northwestern Costa Rica were analyzed for organochlorine (OC) pesticide contamination. Six of 39 amphibians (three of eight species), three of six turtles (two species), one of eight mice (one species) and 19 of 55 birds (five of seven species) contained OCs at levels up to 580 ng/g. The most frequently detected compound in 23 of 108 organisms was p,p'DDE. Dieldrin, delta-BHC, heptachlor, p,p'DDD, and endosulfan II were each found in at least four organisms, while eight other OCs were found in at least one organism. The presence of OCs in taxa from the conservation area indicates the likelihood of long-distance transport of such compounds through the atmosphere.

  20. Tracking performance of unbalanced QPSK demodulators. I - Biphase Costas loop with passive arm filters

    1978-01-01

    Unbalanced quadriphase-shift-keying (QPSK) is an attractive means for transmitting two digital data streams which in general have different average powers, data rates, and data formats. Previous analyses of the tracking performance of Costas loop demodulators of unbalanced QPSK have accounted only for the filtering effect produced by the loop's two arm filters on the equivalent additive noise perturbing the loop. When the bandwidth of these filters is selected on the basis of the order of the data rate, as is typical of optimum Costas loop design, the filtering degradations of the data modulations themselves and the cross-modulation noise produced by their multiplication in the loop often cannot be neglected. The purpose of this paper is to incorporate these additional filtering effects into the analysis. Many of the results obtained herein are in the form of closed-form expressions which can easily be evaluated numerically for design and performance prediction purposes.

    Since 1984, the Seismic Network of the Volcanological and Seismological Observatory of Costa Rica, Universidad Nacional (OVSICORI-UNA) has been recording and registering the seismicity in Costa Rica. Before September 2012, the earthquakes registered by this seismic network in northwestern Costa Rica were moderate to small, except the Cóbano earthquake of March 25, 1990, 13:23, Mw 7.3, lat. 9.648, long. 84.913, depth 20 km; a subduction quake at the entrance of the Gulf of Nicoya and generated peak intensities in the range of MM = VIII near the epicentral area and VI-VII in the Central Valley of Costa Rica. Six years before the installation of the seismic network, OVSICORI-UNA registered two subduction earthquakes in northwestern Costa Rica, specifically on August 23, 1978, at 00:38:32 and 00:50:29 with magnitudes Mw 7.0 (HRVD), Ms 7.0 (ISC) and depths of 58 and 69 km, respectively (EHB Bulletin). On September 5, 2012, at 14:42:02.8 UTC, the seismic network OVSICORI-UNA registered another large subduction earthquake in Nicoya peninsula, northwestern Costa Rica, located 29 km south of Samara, with a depth of 21 km and magnitude Mw 7.6, lat. 9.6392, long. 85.6167. This earthquake was caused by the subduction of the Cocos plate under the Caribbean plate in northwestern Costa Rica. This earthquake was felt throughout the country and also in much of Nicaragua. The instrumental intensity map for the Nicoya earthquake indicates that the earthquake was felt with an intensity of VII-VIII in the Puntarenas and Nicoya Peninsulas, in an area between Liberia, Cañas, Puntarenas, Cabo Blanco, Carrillo, Garza, Sardinal, and Tamarindo in Guanacaste; Nicoya city being the place where the maximum reported intensity of VIII is most notable. An intensity of VIII indicates that damage estimates are moderate to severe, and intensity VII indicates that damage estimates are moderate. According to the National Emergency Commission of Costa Rica, 371 affected communities were reported; most

    The eastern San Francisco Bay region (Contra Costa and Alameda Counties, California) is a geologically complex area divided by faults into a suite of tectonic blocks. Each block contains a unique stratigraphic sequence of Tertiary sediments that in most blocks unconformably overlie Mesozoic sediments. Age and environmental interpretations based on analysis of microfossil assemblages are key factors in interpreting geologic history, structure, and correlation of each block. Much of this data, however, is distributed in unpublished internal reports and memos, and is generally unavailable to the geologic community. In this report the U.S. Geological Survey microfossil data from the Tertiary sediments of Alameda and Contra Costa counties are analyzed and presented in a digital database, which provides a user-friendly summary of the micropaleontologic data, locality information, and biostratigraphic and ecologic interpretations.

    "This paper seeks to (1) identify socioeconomic variables that are expected to generate fertility differentials; (2) hypothesize the direction and magnitude of the effect of each variable by reference to a demand-for-children model; and (3) test empirically the model using evidence from Costa Rica. The estimates are obtained from a ten-percent systematic random sample of all Costa Rican individual-family households. There are 15,924 families in the sample...." The authors specifically seek "to capture the effects of changing relative prices and available income and time constraints on parental preferences for children. Least-squares estimates show statistically significant relationships between household fertility and opportunity cost of time, parental education, occurrence of an extended family, medical care, household sanitation, economic sector of employment, and household stock of nonhuman capital." excerpt

    Scientific knowledge about hydroarsenicism must be disclosed in Latin America. The presence of arsenic has been detected in waters of Costa Rica that have been used for human consumption, in areas of risk; specifically in the province of Cartago, in the cantons of Oreamuno, Central, Paraiso and Alvarado. A quantification of reduced form trivalent arsenic was performed with the methodology of the 7062 Environmental Protection Agency of the United States, through volatile metal hydride generation by flame atomic absorption. The analyzed samples have determined that maintaining the maximum extent permitted by current legislation Costa Rican, 10μg/L. Research areas have corresponded to areas of high risk for its volcanic nature. The vast water supply of the cantons under study, with areas of relative protection circling recharge areas of springs, has caused the population to consume water source underground, but surface direct influence, less influence of volcanic rocks that are found at greater depths.

    Full Text Available This paper analyzes the economic contribution of married and cohabiting women to the household income, in comparison to the income their partners generate, in Costa Rica.  From a perspective of gender roles, human capital theory and female labor participation, this paper examines what variables influence the probability of contribution.  Based on data by the 2014 National Household Survey, this study found that 51% percent of married or cohabiting women do not generate any income, which shows there is an unequal economic relationship in half of Costa Rican households and the males assume the breadwinning role.  Household chores and the number of children reduce the probability of economic contribution.  On the other hand, women with more years of schooling have a higher probability to contribute equally to the couple’s total income.

    Full Text Available A preocupação com o futuro da economia brasileira já chegou aos poetas e às revistas internacionais. Os efeitos da crise do subprime fazem parte dessa preocupação. Alguns desafios, como a internacionalização das empresas brasileiras, a atualização tecnológica da produção e as expectativas de consumo no País ganharam destaque nesse processo. A reunião do G-20, no entanto, mostrou que há diferentes métodos de lidar com a crise, preservando-se a maior influência do modo norte-americano de “fazer negócio”. A inserção brasileira na economia internacional, porém, acompanha mais o novo perfil das economias emergentes, que se desenvolve independentemente da crise. Nesse caminho, a maior dificuldade para a inserção internacional eficiente do Brasil, com manutenção da mobilidade social e da tendência de alta no consumo, continua a ser a frágil relaçãointerna entre educação e competitividade.

    Full Text Available OBJETIVO: Determinar o perfil refracional dos présbitas na Amazônia ocidental brasileira, estabelecendo-se como piloto a cidade de Manaus e nove das sessenta e uma cidades do interior do estado do Amazonas. MÉTODOS: Estudo retrospectivo dos prontuários de 8.225 pacientes. Foram examinadas pessoas maiores de 40 anos, em 10 cidades do estado do Amazonas (Manaus e 09 municípios da hinterlândia, no período de setembro/2008 a dezembro/2011. Os dados foram classificados por faixa etária, sexo, atividade econômica (aposentados ou não, tipo de ametropia e acuidade visual para longe e perto com e sem correção. O método consistiu no exame oftalmológico de rotina que incluiu o exame de refração. A análise estatística dos dados utilizou estudos quantitativos. RESULTADOS: Dos pacientes atendidos, 53,0% eram do sexo feminino; a faixa etária mais prevalente era de 51 a 60 anos; 66,0% não são aposentados e ainda desenvolvem alguma atividade laborativa; a maior prevalência das ametropias registrada foi de astigmatismos diversos (43,0% e a acuidade visual para longe, sem correção, foi de 15,0% com 20/200 e, com correção, foi de 45,0% com 20/30 ou mais; em relação à visão para perto, a acuidade visual foi de 40,0% para J6, sem correção e, de 82,0% para J2 e J1, com correção; as adições utilizadas em 75,0% foram de +2,50 dioptrias ou mais; e 52,0% dos atendimentos foram realizados em Manaus. CONCLUSÃO: Esta pesquisa, ao examinar populações pobres da Amazônia brasileira, corrobora que a falta de óculos para corrigir a visão para perto constitui-se em importante problema de saúde pública nas pessoas acima dos 40 anos, principalmente naquelas que têm dificuldade de acesso a serviços de Oftalmologia.

    Full Text Available ResumoEste estudo avaliou a estrutura de capital de companhias abertas brasileiras, no período de 2005 a 2012, verificando o papel das fontes de financiamento nas quais tais companhias se baseiam. Para tanto, foi avaliada a proporção das dívidas em 3 fontes distintas: as instituições financeiras, o mercado de capitais e as fontes com taxas de juros subsidiadas, estas últimas representando um fator institucional da economia brasileira. Foi utilizada uma amostra de 95 empresas, dentre as 150 maiores empresas com ações negociadas na Bolsa de Valores, Mercadorias e Futuros de São Paulo (BM&FBOVESPA. Por meio de modelos com dados em painel, os resultados mostram que as fontes de financiamento impactam a formação da estrutura de capital das empresas, exercendo influência tanto na alavancagem quanto na maturidade das dívidas. Em relação à alavancagem, empresas que têm maior proporção de seus recursos captados no mercado de capitais são mais alavancadas. O mesmo não acontece com as empresas que têm maior proporção de recursos subsidiados. Em relação à maturidade das dívidas, recursos de diferentes maturidades são captados em diferentes fontes: os recursos de menores maturidades são captados em instituições financeiras e os recursos de maiores maturidades são captados no mercado de capitais e nas fontes com taxas de juros subsidiadas - leia-se Banco Nacional de Desenvolvimento Econômico e Social (BNDES. Comparando-se os recursos do mercado de capitais com os recursos subsidiados, verifica-se que os primeiros têm maior maturidade. Tal resultado pode ser justificado em virtude do crescimento do mercado de capitais brasileiro nos últimos anos, a partir de 2009, de modo que as companhias estão se baseando no mercado de capitais para seus financiamentos de maior maturidade e nos recursos subsidiados, do BNDES, para seus financiamentos de maturidades intermediárias.

    Full Text Available A perda auditiva é uma das privações sensoriais mais comum nos homens. A principal consequência da perda auditiva reside em sua repercussão no desenvolvimento da linguagem oral e, consequentemente, interferindo em todo o processo de aprendizagem da leitura e escrita. O implante coclear é um dispositivo eletrônico, parcialmente implantado, que visa a proporcionar aos seus usuários sensação auditiva próxima ao fisiológico. É uma boa opção aos portadores de surdez sensorioneural profunda, entretanto, não assegura o desenvolvimento das habilidades auditivas e de linguagem oral. Assim, por não desenvolverem a linguagem oral, os indivíduos com implante coclear não podem ser privados da possibilidade da aquisição e do desenvolvimento da linguagem, pois podem fazer isso utilizando outra forma de comunicação – a língua de sinais. O objetivo deste relato é descrever a experiência do atendimento multidisciplinar de uma criança usuária de implante coclear. B.V.S.R. oito anos, gênero masculino, portador de perda auditiva sensorioneural profunda, bilateral desde o período neonatal. Realizou cirurgia de implante coclear aos três anos de idade, sendo acompanhado segundo abordagem aurioral. Devido ao baixo desempenho escolar apresentado, foi discutido com a equipe multidisciplinar e decidido modificar a abordagem, optando-se por iniciar aprendizagem de língua brasileira de sinais.  Após um período de dois anos, segundo a nova abordagem, a criança apresentou considerável evolução em todos os aspectos do desenvolvimento. A mudança de abordagem influenciou positivamente na evolução da criança, pois a mesma alcançou adequado desempenho em diversas habilidades linguísticas.Palavras-chave: Surdez. Implante coclear.

    Full Text Available O conflito de interesses entre executivos e proprietários é uma questão amplamente difundida na academia, já documentada em 1932 por Berle e Means, trazendo à tona o clássico conflito de interesses entre agente e principal discutido pela Teoria da Agência. A premissa por trás da governança corporativa é que as pessoas que estão dentro das corporações não necessariamente agem visando o melhor para os provedores de fundos. Partindo deste pressuposto, o trabalho em questão visa verificar a influência dos aspectos de governança corporativa na eficiência das empresas de capital aberto brasileiras. O estudo une técnicas de otimização estática através de Análise Envoltória de Dados (DEA para identificar a eficiência das empresas de capital aberto, com Dados em Painel para identificar a influência da governança corporativa na eficiência das empresas. Os dados foram coletados manualmente dos relatórios 20-F da Security Exchange Commission (SEC das empresas brasileiras que possuem American Depositary Receipts (ADRs, já que a base de dados não está disponível, no Brasil, de uma forma completa. Grande parte das hipóteses foi confirmada, evidenciando as condições particulares das finanças corporativas no Brasil no que tange a Governança Corporativa. A incipiência do mercado de capitais brasileiro é percebida em várias análises, ressaltando que o histórico do sistema corporativo brasileiro é um dos limitantes da eficiência das empresas. As condições que prevalecem são: (i alta sobreposição propriedade-direção; (ii conselhos de administração de baixa efetividade; (iii em grupos familiares, os papéis dos acionistas, dos conselhos e da direção não são bem definidos; (iv existe pouca clareza quanto à relação benefício-custo da boa governança; (v baixa eficácia dos conselhos de administração; e (vi indícios de conflitos de interesses, relativizados por incentivos explícitos e implícitos.

    Despite high animal diversity in the Neotropics and the largely unregulated use and disposal of pesticides and industrial chemicals in Central America, few data exist regarding accumulation of environmental contaminants in Central American wildlife. In this study we examined accumulation of metals and organochlorine (OC) pesticides in caudal scutes of crocodiles from Belize and Costa Rica. Scutes from Morelet's crocodiles (Crocodylus moreletii) from two sites in northern Belize were analyzed for metals, and scutes from American crocodiles (C. acutus) from one site in Costa Rica were analyzed for metals and OC pesticides. All scutes (n = 25; one scute from each of 25 individuals) contained multiple contaminants. Mercury was the predominant metal detected, occurring in all scutes examined from both species. Other metals detected include cadmium, copper, lead, and zinc. American crocodile scutes from Costa Rica contained multiple OC pesticides, including endrin, methoxychlor, p,p'-DDE, and p,p'-DDT, all of which occurred in 100% of scutes analyzed (n = 6). Mean metal and OC concentrations varied in relation to those previously reported in crocodilian scutes from other localities in North, Central, and South America. OC concentrations in American crocodile scutes were generally higher than those previously reported for other Costa Rican wildlife. Currently, caudal scutes may serve as general, non-lethal indicators of contaminant accumulation in crocodilians and their areas of occurrence. However, a better understanding of the relationships between pollutant concentrations in scutes, internal tissues, and environmental matrices at sample collection sites are needed to improve the utility of scutes in future ecotoxicological investigations.

    2005-12-01

    Over the past eight years, 18 undergraduate students from 12 U.S. and Costa Rican universities and colleges have participated in field research projects investigating coastal tectonics on the Nicoya Peninsula, Costa Rica. These projects have been organized around two different models: 1) a month-long "field camp" with 10 students and 5 project faculty (Keck Geology Consortium Project, 1998), and 2) several two-week field projects with 1-3 students and one faculty advisor (Cal Poly Pomona University and Trinity University). Under the direction of the authors, each of these projects has been carefully designed to provide a new piece to a larger research puzzle. The Nicoya Peninsula lies along Costa Rica's northern Pacific coast inboard of the Middle America Trench where the Cocos and Caribbean plates converge at 10 cm/yr. In 1950, the peninsula was shaken by a ~M 7.7 subduction earthquake that produced widespread damage and 0.5-1.0 m of coseismic coastal uplift. With a large slip deficit since 1950, the Nicoya Peninsula is viewed as a high-potential seismic gap. Field study of uplifted Quaternary marine terraces along the Nicoya coastline provides undergraduate students with a unique opportunity to examine rapid forearc deformation related to large subduction earthquakes. The field research conducted by each of these students provides the basis for a senior thesis at their home institution. In most cases, the students have focused their individual work on separate, but adjacent field areas. Collectively, each of these projects has generated significant data that contribute toward of an ongoing investigation of fore arc tectonics and subduction cycle earthquakes along the Costa Rican Pacific margin.
