    Introduction This report contains a new geologic map at 1:50,000 scale, derived from a set of geologic map databases containing information at a resolution associated with 1:24,000 scale, and a new description of geologic map units and structural relationships in the mapped area. The map database represents the integration of previously published reports and new geologic mapping and field checking by the author (see Sources of Data index map on the map sheet or the Arc-Info coverage pi-so and the textfile pi-so.txt). The descriptive text (below) contains new ideas about the Hayward fault and other faults in the East Bay fault system, as well as new ideas about the geologic units and their relations. These new data are released in digital form in conjunction with the Federal Emergency Management Agency Project Impact in Oakland. The goal of Project Impact is to use geologic information in land-use and emergency services planning to reduce the losses occurring during earthquakes, landslides, and other hazardous geologic events. The USGS, California Division of Mines and Geology, FEMA, California Office of Emergency Services, and City of Oakland participated in the cooperative project. The geologic data in this report were provided in pre-release form to other Project Impact scientists, and served as one of the basic data layers for the analysis of hazard related to earthquake shaking, liquifaction, earthquake induced landsliding, and rainfall induced landsliding. The publication of these data provides an opportunity for regional planners, local, state, and federal agencies, teachers, consultants, and others outside Project Impact who are interested in geologic data to have the new data long before a traditional paper map could be published. Because the database contains information about both the bedrock and surficial deposits, it has practical applications in the study of groundwater and engineering of hillside materials, as well as the study of geologic hazards and the academic research on the geologic history and development of the region.

  9. Entrepreneurship in Costa Rica: stagnation in the transition to innovation

    2015-12-01

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

  10. International trade, and land use intensification and spatial reorganization explain Costa Rica’s forest transition

    2016-03-01

    While tropical deforestation remains widespread, some countries experienced a forest transition—a shift from net deforestation to net reforestation. Costa Rica had one of the highest deforestation rates in the 1980s and is now considered as a model of environmental sustainability, despite being a major producer of bananas and pineapples. We tested three land use processes that are thought to facilitate forest transitions. First, forest transitions may be accompanied by land use displacement through international trade of land-based products, which may undermine the global-scale environmental benefits of national forest protection. Second, reforestation is often associated with land use intensification in agriculture and forestry, allowing for land sparing. Third, this intensification may partly result from a geographical redistribution of land use at the sub-national scale to better match land use with land suitability. These hypotheses were verified for Costa Rica’s forest transition. We also tested whether forest increased mainly in regions with a low ecological value and agriculture expanded in regions with a high ecological value. Intensification and land use redistribution accounted for 76% of land spared during the forest transition, with 32% of this spared area corresponding to net reforestation. Decreasing meat exports led to a contraction of pastures, freeing an area equivalent to 80% of the reforested area. The forest transition in Costa Rica was environmentally beneficial at the global scale, with the reforested area over 1989-2013 corresponding to 130% of the land use displaced abroad through imports of agricultural products. However, expansion of export-oriented cropland caused deforestation in the most ecologically valuable regions of Costa Rica. Moreover, wood extraction from forest plantations increased to produce the pallets needed to export fruits. This highlights the importance of a multi-scale analysis when evaluating causes and impacts of

    The forest transition framework describes the temporal changes of forest areas with economic development. A first phase of forest contraction is followed by a second phase of expansion once a turning point is reached. This framework does not differentiate forest types or ecosystem services, and describes forests regardless of their contribution to human well-being. For several decades, deforestation in many tropical regions has degraded ecosystem services, such as watershed regulation, while increasing provisioning services from agriculture, for example, food. Forest transitions and expansion have been observed in some countries, but their consequences for ecosystem services are often unclear. We analyzed the implications of forest cover change on ecosystem services in Costa Rica, where a forest transition has been suggested. A review of literature and secondary data on forest and ecosystem services in Costa Rica indicated that forest transition might have led to an ecosystem services transition. We modeled and mapped the changes of selected ecosystem services in the upper part of the Reventazón watershed and analyzed how supply changed over time in order to identify possible transitions in ecosystem services. The modeled changes of ecosystem services is similar to the second phase of a forest transition but no turning point was identified, probably because of the limited temporal scope of the analysis. Trends of provisioning and regulating services and their tradeoffs were opposite in different spatial subunits of our study area, which highlights the importance of scale in the analysis of ecosystem services and forest transitions. The ecosystem services transition framework proposed in this study is useful for analyzing the temporal changes of ecosystem services and linking socio-economic drivers to ecosystem services demand at different scales.

  12. Analysis of the transitional dynamics and duration of unemployment in Costa Rica

    Full Text Available This paper analyzes the main factors that explain the duration of unemployment spells and the transitional dynamics between the state of employment, unemployment and inactivity in Costa Rican labor market, using the Continuous Employment Survey for the period between the first quarter of 2012 and the third quarter of 2013. This research focuses mainly on supply-side factors and uses binominal and multinomial logit models in order to determine which variables determine that some people are more likely to be unemployed, Markov matrixes to estimate a series of transitional probabilities for different states in the labor market, and a survival model to characterize the duration of the unemployment spells. We conclude that women are more likely to be unemployed than men, and have smaller probabilities of changing from unemployed to employed. Also, the duration of their unemployment spells is longer. Furthermore, a higher academic level decreases the probabilities for an individual of being unemployed, but increases the duration of the unemployment spell. A correlation between the performance of the economic activity and the probabilities of becoming employed and of becoming inactive is observed.

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

  17. Developing and Transitioning Numerical Air Quality Models to Improve Air Quality and Public Health Decision-Making in El Salvador and Costa Rica As Part of the Servir Applied Sciences Team

    2014-12-01

    In order to enhance the capacity for air quality modeling and improve air quality monitoring and management in the SERVIR Mesoamerica region, members of SERVIR's Applied Sciences Team (AST) are developing national numerical air quality models for El Salvador and Costa Rica. We are working with stakeholders from the El Salvador Ministry of the Environment and Natural Resources (MARN); National University of Costa Rica (UNA); the Costa Rica Ministry of the Environment, Energy, and Telecommunications (MINAET); and Costa Rica National Meteorological Institute (IMN), who are leaders in air quality monitoring and management in the Mesoamerica region. Focusing initially on these institutions will build sustainability in regional modeling activities by developing air quality modeling capability that can be shared with other countries in Mesoamerica. The air quality models are based on the Community Multi-scale Air Quality (CMAQ) model and incorporate meteorological inputs from the Weather Research and Forecasting (WRF) model, as well as national emissions inventories from El Salvador and Costa Rica. The models are being optimized for urban air quality, which is a priority of decision-makers in Mesoamerica. Once experimental versions of the modeling systems are complete, they will be transitioned to servers run by stakeholders in El Salvador and Costa Rica. The numerical air quality models will provide decision support for stakeholders to identify 1) high-priority areas for expanding national ambient air monitoring networks, 2) needed revisions to national air quality regulations, and 3) gaps in national emissions inventories. This project illustrates SERVIR's goal of the transition of science to support decision-making through capacity building in Mesoamerica, and it aligns with the Group on Earth Observations' health societal benefit theme. This presentation will describe technical aspects of the development of the models and outline key steps in our successful

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

    1985-05-01

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

    This paper reviews economic developments in Costa Rica during 1995–97. Costa Rica faced a slump in economic activity in 1995–96 following a sharp deterioration in the public finances and higher inflation associated with the 1993–94 political–economic cycle. To avert a balance-of-payments crisis in early 1995, the authorities increased interest rates, imposed temporary import surcharges, and raised excise taxes, while tightening expenditure and shifting some outlays to 1996. The econom...

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

  19. Mercury Contamination in Costa Rica

    2012-12-01

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

  1. 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.

  2. The Galapagos-OIB signature of the central Costa Rican volcanic front: arc-hotspot interaction

    Although most Central American magmas have a typical arc geochemical signature, magmas in southern Central America have isotopic and trace element compositions with an OIB affinity, similar to the Galapagos hotspot lavas. Our new data for Costa Rica suggest that this signature, unusual for a convergent margin, has a relatively recent origin (Late Miocene-Pliocene ca. 6 Ma). We also show that there was a transition from typical arc magmas (analogous to the modern Nicaraguan volcanic front) to OIB-like magmas. The geographic distribution of the Galapagos signature in recent lavas from southern Central America is present landward from the subduction of the Galapagos hotspot tracks (the Seamount Province and the Cocos/Coiba Ridges) at the Middle American Trench. The higher Pb isotopic ratios, relatively low Nd isotopic ratios and enriched geochemical signature of central Costa Rican magmas can be explained by arc-hotspot interaction. The isotopic ratios of central Costa Rican lavas require the subducting Seamount Province (Northern Galapagos Domain) component, whereas the isotopic ratios of the adakites and alkaline basalts from southern Costa Rica and Panama are in the geochemical range of the subducting Cocos/Coiba Ridges (Central Galapagos Domain). Geological, geochemical, and isotopic evidence collectively indicate that the relatively recent Galapagos-OIB signature in southern Central America represents a geochemical signal from subducting Galapagos hotspot tracks, which started to collide with the margin ~8 Ma ago. The Galapagos hotspot contribution decreases systematically along the volcanic front from central Costa Rica to NW Nicaragua.

  4. Costa Rica saves infants' lives.

    1988-01-01

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

  9. Active Subduction on Both Coasts of Costa Rica Does not Represent an Important Tsunami Hazard

    Science.gov (United States)

    Protti, M.; Gonzalez, V.

    2007-05-01

    Costa Rica, on the southern terminus of the Middle American Trench is being affected by active subduction on both, along the Pacific coast as well as on its Caribbean coast. Three main subduction segments can be recognized along the Pacific coast: 1) under northwestern Costa Rica, off Papagayo Gulf and Nicoya peninsula, the Cocos plate is subducting under the Caribbean plate; 2) under southern Costa Rica (Osa and Burica peninsulas) the Cocos plate subducts under the Panama Block and 3) in the central Pacific coast (between Nicoya and Osa peninsulas) the Cocos plate subducts under a shear zone that marks the transition between the Caribbean and the Cocos plate. Along the Caribbean coast, south of Puerto Limon, the Caribbean plate subducts under the Panama block. Large subduction earthquakes occur under the Nicoya peninsula, Osa peninsula and south of Limon. Most of the rupture area of these large events lies below land so the deformation of the ocean floor is minimal and therefore the tsunamis they generate are small. No large subduction earthquakes occur under the central Pacific coast of Costa Rica due to the subduction of small sea mounts that act as small asperities without potential to accumulate large amounts of slip. For this reason the region between Nicoya and Osa peninsulas is not an important tsunamigenic zone.

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

    1989-01-01

    Costa Rica's La Selva-Braulio Carrillo complex encompasses a 60-km protected corridor of Caribbean rain and cloud forest extending from 30 m at the La Selva Biological Station to 2,906 m at the top of Volcán Barva. The 52,000-ha complex covers four life zones and two transitional zones, including tropical wet forest, tropical wet forest cool-transition, tropical premontane wet-transition rain forest, tropical premontane rain forest, lower montane rain forest, and montane rain forest. Located in the northeastern part of the country, the area is representative of Central American Caribbean slope forests that extend from Mexico to Panama. The extensive elevational gradient of the complex provides protected habitat for a variety of altitudinal migrants. With support from the National Geographic Society and Rice Foundation, the Organization for Tropical Studies organized a biological survey of the complex in early 1986. The mammal team worked at six sites along the elevational transect established by the expedition: 300 m, 700 m, 1,000 m, 1,500 m, 2,050 m, and 2,600 m. We supplemented our collecting records with unpublished records made available by colleagues, records in the published literature, and specimens in museum collections. In addition, observations recorded by a variety of observers at the La Selva Biological Station are summarized. The mammal fauna of the complex comprises 142 species including 79 bats, 23 rodents, 15 carnivores, 7 marsupials, 6 edentates, 4 artiodactyls, 3 primates, 2 rabbits, 2 shrews, and 1 perissodactyl. At least 10 additional species are likely to occur there. The only species of mammal likely to have been extirpated from the area is the giant anteater. Recognizing the importance of the area to wildlife and to mankind in general, the government of Costa Rica added 13,500 ha to the complex on 13 April 1986. This area, previously known as the “Zona Protectora,” provided the mid-elevational link between the lowlands of the La Selva

Changing rooms for bathers, and a night club, in the basement. Restaurant and bar on the ground floor. Twelve living apartments on the six standard floor levels; two apartments per storey. Porter's house in the attic. As the foundations are in the sand, and the building is exposed to strong coastal winds, the structural design has, as interesting features, the foundation ribbed slab and the transversal portal frames, which are W shaped on the ground level. This arrangement makes the edifice look lighter and it acquires a more dynamic plasticity.En la Costa del Sol de Almería y a muy pocos metros de la orilla del mar, se ha construido este edificio de apartamentos. Su programa es el siguiente: casetas de baño y sala de fiestas, en sótano; restaurante-bar, en planta baja; doce viviendas, en las seis plantas tipo, con dos viviendas por planta; y vivienda del portero en ático. Cimentado sobre arena y expuesto a los fuertes vientos que azotan la costa, la solución estructural ofrece el interés de su tipo de cimentación por placa nervada, y de sus pórticos transversales que en planta baja adoptan forma de W, con lo que el edificio adquiere un aspecto de mayor ligereza y de dinamismo plástico.

    2016-07-01

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

  8. Accumulation of atmospheric sulfur in some Costa Rican soils

    Science.gov (United States)

    Bern, Carleton R.; Townsend, Alan R.

    2013-01-01

    Sulfur is one of the macronutrient elements whose sources to terrestrial ecosystems should shift from dominance by rock-weathering to atmospheric deposition as soils and underlying substrate undergo progressive weathering and leaching. However, the nature and timing of this transition is not well known. We investigated sources of sulfur to tropical rain forests growing on basalt-derived soils in the Osa Peninsula region of Costa Rica. Sulfur sources were examined using stable isotope ratios (δ34S) and compared to chemical indices of soil development. The most weathered soils, and the forests they supported, are dominated by atmospheric sulfur, while a less weathered soil type contains both rock-derived and atmospheric sulfur. Patterns of increasing δ34S with increasing soil sulfur concentration across the landscape suggest atmospheric sulfur is accumulating, and little rock-derived sulfur has been retained. Soil sulfur, minus adsorbed sulfate, is correlated with carbon and nitrogen, implying that sulfur accumulation occurs as plants and microbes incorporate sulfur into organic matter. Only the lower depth increments of the more weathered soils contained significant adsorbed sulfate. The evidence suggests a pattern of soil development in which sulfur-bearing minerals in rock, such as sulfides, weather early relative to other minerals, and the released sulfate is leached away. Sulfur added via atmospheric deposition is retained as organic matter accumulates in the soil profile. Adsorbed sulfate accumulates later, driven by changes in soil chemistry and mineralogy. These aspects of sulfur behavior during pedogenesis in this environment may hasten the transition to dominance by atmospheric sources.

    Costa Rica has a diversity of volcanic crater lakes that can be classified into two groups: hot and cold lakes. The country contains at least 5% of the world's hot lakes. Costa Rica has 2 hot hyperacidic lakes, both of them on active volcanoes, the Rincón de la Vieja (38.0°C, pH = 0 - 1) and the Poás Laguna Caliente (36.1°C - 56°C, pH = 0.55 - 0.74), nowadays the Poás hot lake is the most active crater lake in the world, with more than 200 eruptions only on 2010. One of the most studied cold crater lakes is Irazú (13°C, pH = 3.5), that used to contain bubbling and clear areas of upwelling involving CO2 liberation and subaqueous fumaroles with temperatures up to 50°C, but since 2005 the lake presents an important descend until April 2010 when it disappeared. On February 9, 2003, Irazú's lake underwent a drastic change of color, from clear green to mustard with reddish loops, similar to the color of the waters of Lake Nyos after the gas burst of August 1986. Other studied cold lakes include Botos, Chato, and Tenorio, all at the summit of Quaternary volcanoes as well as Barva and Danta, located in recent pyroclastic cones. Some cold lakes are located in Holocene maar-type explosion craters, among them are Congo, Bosque Alegre, Hule, and Río Cuarto. These last two have undergone repeated rapid reddish color changes over the last 10 years, in association with fish kills and the liberation of apparently sulfurous scents. On March 2010, University of Costa Rica was the host of the 7th Workshop on Volcanic Lakes, part of the Commission of Volcanic Lakes of the IAVCEI, 51 participants from 14 countries attended the workshop; they presented 27 talks and 17 posters, also they visited and sample 4 of the lakes mentioned above (Botos, Irazú, Río Cuarto and Hule).

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

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

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

Una buena parte de la atención se pone en el ritmo de la fecundidad en las etapas umbral, temprana y tardía de la disminución de la fecundidad que este país experimentó durante los años sesenta y principios de los setenta. Los resultados muestran bastante similitud en el tempo de la reproducción en los diferentes niveles paridez y áreas geográficas. Sin embargo, un análisis de las variables del entorno que afectan espaciamiento de los nacimientos muestra diferencias entre las zonas urbanas y rurales. Por último, se postula que el reciente estancamiento en las tasas de período puede ser una consecuencia de los cambios en el tempo de construcción de la familia, con mujeres de baja paridez que postergan los nacimientos, lo que contrarresta las tendencias de descenso que generan las mujeres de mayor paridez quienes aún pueden estar restringiendo su reproducción.ABSTRACTThis paper uses data from the Latin American Comparative Fertility Surveys as well as from the World Fertility Survey to study trends and differentials in birthspacing among ever married women in Costa Rica during the period 1945-1974. A good deal of attention is placed on the pace of fertility in threshold, early and late stages of the fertility decline that this country experienced during the sixties and early seventies. The results show a good deal of similarity in the tempo of reproduction across parities and geographical areas.However, an analysis of the background variables affecting birthspacing shows differences between urban and rural zones. Finally, it is postulated that the recent plateau in period rates may be a consequence of changes in the tempo of

    Full Text Available El abuso sexual es un conjunto de actitudes de un sujeto que realiza en detrimento de otro, generalmente menor, para su autosatisfacción. Las estadísticas de los diferentes países apuntan a que se está convirtiendo en una epidemia que nos está asfixiando. La prevención de la revictimización, una política establecida en el Poder Judicial de Costa Rica desde hace más de diez años, dio como fruto la conformación de los equipos interdisciplinarios. Al inicio, estos abarcaron una serie de disciplinas tan disímiles entre sí, que comprendían tanto el derecho, como la medicina, la psicología, el trabajo social y la psiquiatría. Con el paso de los años los equipos se fueron reduciendo hasta quedar conformados por el psicólogo, el trabajador social y el médico forense, que asiste a una reunión semanal con ellos y en donde se discuten las diferentes conclusiones de las tres disciplinas. Hoy en día son equipos establecidos prácticamente en todas las cabeceras de provincia de nuestro país con funciones periciales muy específicas en el tratamiento legal de las causas de los delitos sexuales.Sexual Abuse is series of actitudes of a subject, Which he realize in detriment of other, usually younger, for his self satisfaction.

  10. Call for a change in research funding priorities: the example of mental health in Costa Rica.

    2014-10-01

    The World Health Organization (WHO) Mental Health Action Plan 2013-2020 urges its Member States to strengthen leadership in mental health, ensure mental and social health interventions in community-based settings, promote mental health and strengthen information systems, and increase evidence and research for mental health. Although Costa Rica has strongly invested in public health and successfully reduced the burden of nutritional and infectious diseases, its transitional epidemiological pattern, population growth, and immigration from unstable neighboring countries has shifted the burden to chronic disorders. Although policies for chronic disorders have been in place for several decades, mental disorders have not been included. Recently, as the Ministry of Health of Costa Rica developed a Mental Health Policy for 2013-2020, it became evident that the country needs epidemiological data to prioritize evidence-based intervention areas. This article stresses the importance of conducting local epidemiological studies on mental health, and calls for changes in research funding priorities by public and private national and international funding agencies in order to follow the WHO Mental Health Action Plan.

  11. Active deformation near the Nicoya Peninsula, northwestern Costa Rica, between 1996 and 2010: Interseismic megathrust coupling

    We use campaign and continuous GPS measurements at 49 sites between 1996 and 2010 to describe the long-term active deformation in and near the Nicoya Peninsula, northwestern Costa Rica. The observed deformation reveals partial partitioning of the Cocos-Caribbean oblique convergence into trench-parallel forearc sliver motion and less oblique thrusting on the subduction interface. The northern Costa Rican forearc translates northwestward as a whole ridge block at 11 ± 1 mm/yr relative to the stable Caribbean. The transition from the forearc to the stable Caribbean occurs in a narrow deforming zone of ˜16 km wide. Subduction thrust earthquakes take 2/3 of the trench-parallel component of the plate convergence; however, surface deformation caused by interseismic megathrust coupling is primarily trench-normal. Two fully coupled patches, one located offshore Nicoya centered at ˜15 km depth and the other located inland centered at ˜24 km depth, are identified in Nicoya with the potential to generate an Mw 7.8 1950-type earthquake. Another fully coupled patch SE of Nicoya coincides with the rupture region of the 1990 Nicoya Gulf earthquake. Interface microearthquakes, non-volcanic tremor, low-frequency earthquakes, and transient slow-slip events generally occur in the intermediately to weakly coupled regions.

    Full Text Available La diabetes mellitus neonatal es un raro desorden metabólico usualmente desarrollado en las primeras 6 semanas de vida, secundario a un grupo de mutaciones y defectos del desarrollo pancreático que puede desembocar en una catástrofe clínica si no se identifica tempranamente; se divide en una variante transitoria y una permanente, siendo la primera la más frecuente, con cerca de un 60% de los casos. El manejo inicial de ambas variantes es la insulinoterapia intensiva, que en la variante transitoria puede suspenderse usualmente en los primeros meses de vida. El síndrome de disregulación inmunológica, poliendocrinopatía y enteropatía ligada a X (IPEX por sus siglas en inglés, es una causa extremadamente rara de la variante permanente, casi siempre mortal, caracterizada por un inmunocompromiso severo, enteropatía, diabetes y dermatitis. En el estudio se describen 4 casos de diabetes mellitus neonatal diagnosticados en el Hospital Nacional de Niños de San José, Costa Rica: 2 correspondientes a una diabetes mellitus neonatal transitoria, 2 a una diabetes mellitus neonatal permanente y 1 de ellos correspondiente a un síndrome de IPEX.

    Full Text Available La horticultura en Costa Rica se ha desarrollado principalmente a campo abierto y se ha concentrado en el Valle Central donde predominan las actividades de expansión urbanística y comercial. Muchos de los problemas asociados a la producción hortícola se centran en la alta presencia de plagas y enfermedades que obligan al productor a utilizar plaguicidas químicos con consecuencias nocivas para el ambiente: la horticultura a campo abierto se vuelve muy contaminante e insostenible. Una alternativa productiva pueden ser los sistemas de cultivos protegidos, en los que se usan estructuras, materiales y equipo; posibilitan la producción de hortalizas en climas adversos y facilitan el control de plagas y enfermedades. Estos sistemas se han usado ampliamente a nivel mundial con gran éxito, pero a nivel del trópico es necesaria la investigación en este campo con el objetivo de implementar o modificar el sistema para que favorezca la producción sostenible de hortalizas.

Posteriormente se presenta la situación de la oferta y la demanda actual de estos productos, destacando las principales limitaciones que experimenta su desarrollo comercial, así como el potencial que posee el país en esta materia, basado en su extraordinaria biodiversidad. Además, se hace mención de las entidades involucradas en esta temática. Finalmente se hacen algunas consideraciones adicionales relacionadas con la toxicidad de estos productos y sobre la importancia de los conocimientos etnobotánicos en esta materia. Entre las especies de plantas que más se mencionan en la bibliografía consultada están Allium sativum, Annona reticulata, Azadirachta indica, Capsicum frutescens, Chenopodium Ambrosiodes, Gliricidia sepium, Quassia amara y Ryania speciosa. Se resalta el hecho de que hasta la fecha, tanto su uso artesanal como su desarrollo comercial son mínimos, en relación con el potencial existente en el país. Con excepción de dos productos, los pocos bioplaguicidas de origen vegetal que se comercializan son importados.

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

Objective: To describe the operations, activities, and resources of the DICs and the DISs affiliated with public institutions of Costa Rica, and their adjustment to the provisions set forth by the PAHO. Methods: Descriptive study conducted in May 2003. The officers in charge of each of the seven public DICs or DISs in Costa Rica were interviewed, and inquiries were made regarding aspects of the structure and process of their centers. Results: In Costa Rica there are seven public drug information units, that is, four DICs and three DISs. One of the DICs is located in this university, and the remaining six centers and services are in located in hospitals. Five of the centers do not have the primary sources required by the PAHO. Fifteen out of the 36 tertiary sources recommended are not available in any of the centers. 100% of the information units carry out four main activities: answering inquiries from the hospital community, answering inquiries from users outside the hospital, implementing education programs for patients and risk groups, and rotation programs for student training. Conclusions: The activities developed by the DISs and the DICs in Costa Rica are similar to each other; they respond not only to the PAHO’s guidelines, but they also have similarities with the activities and operations of other DICs worldwide. Primary, secondary, and tertiary bibliographical support must be strengthened.

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.

  2. Importance of orographic precipitation to the water resources of Monteverde, Costa Rica

    Science.gov (United States)

    Guswa, Andrew J.; Rhodes, Amy L.; Newell, Silvia E.

    2007-10-01

    Monteverde, Costa Rica harbors montane forests that exemplify the delicate balances among climate, hydrology, habitat, and development. Most of the annual precipitation to this region arrives during the wet season, but the importance of orographic precipitation during the dry and transitional seasons should not be underestimated. Development associated with ecotourism has put significant stress on water resources, and recent work has shown evidence that changes in regional land-cover and global climate may lead to reduced precipitation and cloud cover and a subsequent decline in endemic species. Precipitation samples collected from 2003 to 2005 reveal a seasonal signal in stable isotope composition, as measured by δ 18O and δ 2H, that is heaviest during the dry and transitional seasons. Attenuated versions of this signal propagate through to stream samples and provide a means of determining the importance of precipitation delivered by the trade winds during the dry and transitional seasons to water resources for the region. Results from six catchments on the leeward slope indicate that topography exerts a strong control on the importance of orographic precipitation to stream baseflow. The contributions are greatest in those catchments that are close to the Brillante Gap in the Continental Divide. Differences in the temporal variation of precipitation and streamflow isotope compositions provide insight to the hydrologic pathways that move water to the streams.

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

    Full Text Available La estricnina es un alcaloide de origen vegetal, de efecto convulsivante el cual ha sido usado en Costa Rica como plaguicida y rodenticida y también como adulterante de drogas de abuso. Su utilización terapéutica ha sido rechazada. La intoxicación por este tóxico es rara debido al uso actualmente restringido en Costa Rica para la eliminación de perros callejeros por personal de salud. La sintomatología, primordialmente neurológica y cardiorrespiratoria, es de diagnostico clínico y de laboratorio, según esta revisión e la literatura reciente. Los principales hallazgos postmortem son rigidez cadavérica precoz e intensa y síndrome asfíctico. Los registros de la Sección de Patología Forense del Organismo de Investigación Judicial de Costa Rica presentan desde 1990, únicamente dos casos de muerte por intoxicación con estricnina. Se trata de mujeres, que presentaron la rigidez anotada, corroborándose por la escena de muerte y en el laboratorio. La baja frecuencia se debe a la dificultad para conseguir la estricnina.Strychinine is an alcaloid of plant origin and convulsive effect which has beenused in Costa Rica as a pesticide androdenticide, as well as adulterant in abused drugs. Its therapeutic use has been rejected. Poisoning with this substance is not common because n Costa Rica its use is currently restricted to the elimination of street dogs practiced by sanitary personnel. The symptons, basically neuroogic and cardiorespiratory, require clinical and laboratory analysis, according to the present review of recent literature. The main post-mortem findings are early rigor mortis and an asfictic syndrome.

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

    Seven species of Orbiniidae are described from the Pacific coast of Costa Rica including two new species. Leodamas hamatus n. sp., a commonly occurring species on the coast of Pacific Costa Rica, is described from 11‒18 m in the Gulf of Nicoya and Bahia Culebra. This species is unusual in that the neuropodial uncini differ morphologically from anterior to posterior in the thorax. Scoloplos cryptospinigerus n. sp. is described from 18-22 m in the Gulf of Nicoya and has only a few short, toothed spines amidst numerous capillary setae in most of the thoracic neuropodia. This arrangement of thoracic neurosetae is unusual and has been seen only in one other described species of Scoloplos from Australia.

    Transport of crab zoeae, megalopae, and early juveniles was measured in a mangrove estero (creek) in the Gulf of Nicoya on the Pacific coast of Costa Rica. In 1987, larvae were collected by quantitative pumping from a platform moored in the mouth of the estero. During each sampling period, larvae were collected every 2 h over five consecutive tidal cycles. The investigation consisted of one spring-tide sampling period and one neap-tide sampling period during each season of the year (dry season, dry-rainy transition, rainy season, and rainy-dry transition). Hourly tidal heights were available for each sampling period. A model for hindcasting tidal volume flux from the change in sea level over each half tidal cycle was developed from measurements made in the estero in 1989. This model was used to calculate tidal volume flux and consequent larval flux during each of the 1987 sampling periods. There was a net export of zoea stage I of four taxonomic groups ( Uca spp., Pinnotheres spp., Petrolistes spp., and Grapsidae) during most sampling periods, while there was a net import of zoea stage I of only two groups ( Pinnixa spp. and Xanthidae). Intermediate and late zoeal stages of all taxonomic groups were generally imported into the estero, as were megalopal and juvenile stages. Quantitative estimates of net larval transport corroborated earlier qualitative models of larval transport that had been based on observations of the vertical distribution of larvae in the water column.

    The third meeting organised by the European Federation of Biotechnology (EFB) on advances in Applied Synthetic Biotechnology in Europe (ASBE) was held in Costa da Caparica, Portugal, in February 2016. Abundant novel applications in synthetic biology were described in the six sessions of the meeting, which was divided into technology and tools for synthetic biology (I, II and III), bionanoscience, biosynthetic pathways and enzyme synthetic biology, and metabolic engineering and chemical manufacturing. The meeting presented numerous methods for the development of novel synthetic strains, synthetic biological tools and synthetic biology applications. With the aid of synthetic biology, production costs of chemicals, metabolites and food products are expected to decrease, by generating sustainable biochemical production of such resources. Also, such synthetic biological advances could be applied for medical purposes, as in pharmaceuticals and for biosensors. Recurrent, linked themes throughout the meeting were the shortage of resources, the world's transition into a bioeconomy, and how synthetic biology is helping tackle these issues through cutting-edge technologies. While there are still limitations in synthetic biology research, innovation is propelling the development of technology, the standardisation of synthetic biological tools and the use of suitable host organisms. These developments are laying a foundation to providing a future where cutting-edge research could generate potential solutions to society's pressing issues, thus incentivising a transition into a bioeconomy.

    Science.gov (United States)

    Campo-Engelstein, Lisa; Meagher, Karen

    2011-08-01

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

    2001-06-01

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

    2008-01-01

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

  1. Horizontal principal stress orientation in the Costa Rica Seismogenesis Project (CRISP) transect from borehole breakouts

    Malinverno, A.; Saito, S.; Vannucchi, P.

    2016-01-01

    The Costa Rica Seismogenesis Project (CRISP) drilled the Pacific margin of the Middle America Trench just north of where the Cocos Ridge enters the subduction zone, resulting in basal erosion of the upper plate. Here we report the orientations of the maximum horizontal principal stress (SHmax) from borehole breakouts detected by logging-while-drilling and wireline downhole measurements. All SHmax directions were estimated in the sediment cover of the margin, above the deeper rocks of the deformed margin wedge. We observe three overall SHmax orientations: NNE-SSW (25° azimuth) in the deepest interval drilled at the upper slope Site U1379; ENE-WSW (82°) in the rest of Site U1379 and in Site U1413, also drilled in the upper slope; and NNW-SSE (157°) in the mid-slope Site U1378. Our preferred interpretation is that the deepest interval of Site U1379 records the stress conditions in the underlying margin wedge, as SHmax is parallel to the direction of the Cocos-Caribbean plate convergence and of the compressional axes of plate boundary fault earthquakes. The variable SHmax directions observed elsewhere are likely due to the effect of a network of normal faults that subdivide the sediment cover into a number of independently deforming blocks. In addition, the observed SHmax directions may be influenced by the subducting Cocos Ridge, which acts as an indenter causing oblique deformation, and by the transition to seismogenic subduction along the plate boundary fault.

  2. Assessment of health policy in Costa Rica--some preliminary remarks.

    Eriksson, C G; Mohs, E; Eriksson, B

    1991-01-01

    Costa Rica is one of the world's success stories in primary health care. During the past 20 years the country has experienced a demographic and epidemiological transition. However, during the 80's the economic recession severely affected the country. The social, economic, political and geographic contexts are important for the assessment of health policy. The longstanding democracy, investments in public education and health all contribute to the peace and stability. Assessment of health policy needs both a quantitative and qualitative approach. The policy-making process--how policies are made, translated into action and evaluated--is a research challenge. The national health policy 1986-1990 includes commitment to Health for All strategy; development of the National Health Care System; strengthening of the health care infrastructure; consolidation of health achievements and undertaking of new problems and approaches on integral care for the population; community participation in all health care system activities; and health care priorities. Important research issues are the relationship between the needs of the population and health policy development and the impacts of health policy on the health of the population. A comprehensive study of policy-making includes studies of policy content, process, output and evaluation of impacts (including economy of health policy), and analysis for policy, i.e. information for policy making, process and policy advocacy. Recent successful health policy issues are child health and HIV/AIDS, while water pollution and traffic accidents have been more problematic policy issues.

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

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

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

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

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

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

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

  17. Structural and hydrologic controls of subduction zone seismogenic behavior along the Nicoya Peninsula, Costa Rica

    Audet, P.; Schwartz, S. Y.

    2012-12-01

    Subduction zone thrust faults exhibit variations in rupture behavior that include potentially great (M>8) earthquakes and slow propagating (M~7) slip. The factors controlling transitions in frictional properties are loosely constrained and include variations in temperature, lithologies and pore-fluid pressures. Along the Nicoya Peninsula, Costa Rica, the seismogenic zone is characterized by strong heterogeneity in mechanical properties and a lateral change in the origin of the subducting plate. We use observations of scattered teleseismic waves to examine structural properties (compressional to shear velocity ratio, or Vp/Vs) of the subduction zone elements beneath the Nicoya Peninsula and report two findings: 1) evidence for inferred high pore fluid pressures within the subducting oceanic crust, in agreement with results globally and 2) contrasts from lower to higher forearc and oceanic Vp/Vs ratios from northwest to southeast that correlate with changes in interseismic locking, seismogenic behavior and the origin of the subducting plate. We interpret these results as representing differences in permeability and thus fluid overpressures in the oceanic crust. We suggest that enhanced permeability of the East Pacific Rise (EPR) crust being subducted beneath the northwest portion of the Nicoya Peninsula results in lower pore-fluid pressure, higher effective stress and strength compared with the Cocos Nazca Spreading Center (CNS) crust, subducted beneath the southeastern Nicoya Peninsula. The higher pore-fluid pressure within the CNS crust is consistent with the lower coupling and large slow slip events observed in this region. We posit that the elevated fluid pressures here are periodically released allowing fluids to migrate into the upper plate reducing its velocities. Changes in hydrologic properties resulting from differences in the structural integrity of the subducting oceanic crust appear to control the seismogenic segmentation along the Nicoya Peninsula. (a

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

    This article describes three fragmentary images on the origin of the Costa Rican drama from a contemporary point of view. Through these images it is shown that the Costa Rican theater lacks a native mythology, that female production comes late in its history, and that the Costa Rican theater emerges more as a political  and a entertainment necessity, than in relation to the development of the national dramatic literature. Se presenta en este artículo tres imágenes fragmentarias sobre el or...

    Full Text Available The new synonymy “Scutigera Vesuviana” [O. G. Costa], 1839 = Lithobius forficatus (Linnaeus, 1758 syn. nov. is proposed. “Lithobius vesuvianus”, a name erroneously attributed to Achille instead of Oronzio Gabriele Costa and by the authors of a species named but never described different from “Scutigera Vesuviana” [O. G. Costa], 1839, is equated to this latter. The few records of “Scutigera Vesuviana” quoted by the authors after the original description, critically revised, must be referred to Scutigera coleoptrata (Linnaeus, 1758.

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

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

    Morales-Ramírez, A

    2001-12-01

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

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

La 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.

    Full Text Available This paper presents the results of estimating three leading indicators for the turning points of the economic activity in Costa Rica. 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.

    2001-12-01

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

    2011-01-01

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

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

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

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

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

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

    2002-12-01

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

    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.

    AIM: To evaluate several risk factors for gastric cancer (GC) in Costa Rican regions with contrasting GC incidence rate (GCIR). METHODS: According to GCIR, 191 Helicobacter pylori ( H pylori)-positive patients were classified into groups A (high GCIR, n = 101) and B (low GCIR, n = 90). Human DNA obtained from biopsy specimens was used in the determination of polymorphisms of the genes coding for interleukin (IL)-1o play a major role in GCIR variability in Costa Rica.

    The extensive development of genealogical studies based on archival documents has provided powerful support for genetic research in Costa Rica over the past quarter century. As a result, several questions of population history have been answered, such as those involving hereditary illnesses, suggesting additional avenues and questions as well. Similarly, the preservation of massive amounts of historical documentation highlights the major advantages that the Costa Rican population offers to genetic research.

    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 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.

    The studies on marine copepods of Costa Rica started in the 1990's and focused on the largest coastal-estuarine systems in the country, particularly along the Pacific coast. Diversity is widely variable among these systems: 40 species have been recorded in the Culebra Bay influenced by upwelling, northern Pacific coast, only 12 in the Gulf of Nicoya estuarine system, and 38 in Golfo Dulce, an anoxic basin in the southern Pacific coast of the country. Freshwater environments of Costa Rica are known to harbor a moderate diversity of continental copepods (25 species), which includes 6 calanoids, 17 cyclopoids and only two harpacticoids. Of the +100 freshwater species recorded in Central America, six are known only from Costa Rica, and one appears to be endemic to this country. The freshwater copepod fauna of Costa Rica is clearly the best known in Central America. Overall, six of the 10 orders of Copepoda are reported from Costa Rica. A previous summary by 2001 of the free-living copepod diversity in the country included 80 marine species (67 pelagic, 13 benthic). By 2009, the number of marine species increased to 209: 164 from the Pacific (49% of the copepod fauna from the Eastern Tropical Pacific) and 45 from the Caribbean coast (8% of species known from the Caribbean Basin). Both the Caribbean and Pacific species lists are growing. Additional collections of copepods at Cocos Island, an oceanic island 530 km away of the Pacific coast, have revealed many new records, including five new marine species from Costa Rica. Currently, the known diversity of marine copepods of Costa Rica is still in development and represents up to 52.6% of the total marine microcrustaceans recorded in the country. Future sampling and taxonomic efforts in the marine habitats should emphasize oceanic environments including deep waters but also littoral communities. Several Costa Rican records of freshwater copepods are likely to represent undescribed species. Also, the biogeographic relevance

    Full Text Available Introduction. Home visit is the main strategy of primary care by bringing health services to the homes and workplaces of people, which allows knowing the needs of the population firsthand. Thus, home visit by the ATAP represents the first contact of the individual, family and community with the health system, with significant benefits both individually and collectively. This research responds to the need to identify the elements that the home visiting program needs to improve modify or replace in order to maximize the provision of this service.Method. It is a qualitative, observational analytic study. Data were collected through documentary research, key informant interviews and focus group. The analysis was performed from the grounded theory.Results. The main results showed the existence of elements at the level of the health system, home visiting program and the figure of the ATAP that should be reviewed, modified or replaced to the home visit, thus it has bigger and better results for the population and the health system.Conclusion. The Home Visiting Program is strength of the Costa Rican health system to address health inequities. However, it is imperative to make decisions and implementation of actions that promote the improvement and increased results of the home visit at a family and community level.

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.

    Congram, Derek R

    2008-07-01

    This case report describes the search for a clandestine grave in Costa Rica for which the police sought the assistance of an archaeologist. An anonymous informant suggested that the victim had been kidnapped and murdered, placed in a shallow grave in the woods, then covered with lime and cement. A search of the area to detect conventional signs of burial (e.g., slumping, different plant growth) resulted in excavation of unrelated features of past disturbance. Different aspects of the grave including the deposition of cement powder over the body prevented its initial discovery. Improvisation of conventional archaeological excavation methods and use of police familiar with archaeological excavation resulted in the location of the grave and exhumation of the victim without loss of important contextual evidence that supported testimony on the cause of death. The taphonomic effects of high-lying ground water and lime in the tropical burial environment are briefly discussed. Recommendations such as the construction of a temporary sump to lower the ground water level in the grave during excavation are made to assist in similar investigations in the future.

    2015-01-01

    Cervical and uterine cancer continues to be an important issue for women around the world, although neoplasia has the greatest demonstrated potential for prevention. Costa Rica has achieved important advances in the reduction of the incidence and mortality of these cancers since the last century. This is the result of a series of policies, programmes, and plans, not only at the level of the health care system, but also in other areas. Increased access for women to care in health centres, fundamentally at the primary level, has been vital, as has ensuring the quality of cytology readings and access to diagnosis and treatment for precursor lesions for in situ and invasive cancers. Despite all of these achievements, there are still challenges to be overcome, which are widespread in many countries in Latin America and the Caribbean. It is important to learn from the experiences of other countries in order to improve women's health not only as a health objective, but also as an ethical imperative to promote the exercise of women's rights to life and health.

    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 Moín 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 microg/g, respectively) and lower in Moín Bay (3.4% and 52 microg/g, respectively). Zinc mean concentration was also higher in Golfito Bay (96 microg/g), but lower in Culebra Bay (66 microg/g). Lead mean concentration was higher in Moín Bay (6.4 microg/g) and lower in Culebra Bay (3.0 microg/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 Moín Bay and the Gulf of Nicoya showed an intermediate condition.

    In agreement with the Broecker and Penn two-boxes model, I generated a biogeochemical balance model for the Gulf of Nicoya (Guanacaste, Costa Rica) using two nutrient reservoirs: surface water and deep water. The mixing zone was located at a depth of 20 m. There is a balance between surface waters descending to the bottom and upwelling waters that carry nutrients and other chemical elements to the surface. The main source of nitrogen (nitrate), was the outlet of the Tempisque and Tárcoles rivers. The Gulf of Nicoya is a net source of Dissolved Inorganic Nitrogen (DIN) with an availability rate of 87 x 10(3) mol day(-1) in the dry season and 3044 x 10(3) mol day(-1)in the rainy season. Dissolved Inorganic Phosphate (DIP) was estimated in 27 mol day(-1) in the dry season and 207 mol day(-1) in the rainy season. The dynamics of these biolimited nutrients, in relation to runoff seasonal variations, fits the biological processes reported for the gulf, for example, for variations in primary productivity levels, and maturity and reproduction seasons for species with short and long life cycles.

    Three daily samplings of the phytoplankton community were made at two consecutive days in March, April, May, September, October, November and December 1997, at Punta Morales, Golfo de Nicoya, Costa Rica. Samples were collected during each tide at depths of 50% and 10% of light penetration using a Niskin bottle. A total of 43 taxa were identified. Centric diatoms, pennates and flagellates represented 90% of total phytoplankton abundance. In the phytoplankton fraction (cells > 30 microm), diatoms were the most abundant group, and Skeletonema costatum (32%) dominated. In nannophytoplankton (cells < 30 microm), Chaetoceros (23.7%) was the most abundant taxon, followed by flagellates (23%) and Cylindrotheca closterium (13.1%). These results agree with previous surveys and suggest that a typical net phytoplankton community persist through time in the Punta Morales zone. The number of nannophytoplankton fraction cells varied seasonally and suggests quantitative changes in species abundance, with possible modifications of cellular size or chain length in filamentous species. The codominance between S. costatum and Chaetoceros spp. during the rainy season suggested the ocurrence of an early ecological sucession, and nutrients could be the factor generating such population changes.

    Beginning in early 2006, an ocular disease of unknown etiology was routinely observed in American crocodiles (Crocodylus acutus) inhabiting the highly polluted Tarcoles River in west-central Costa Rica. We examined the nature and incidence of ocular disease in Tarcoles crocodiles and assessed the possible association between the disease and accumulation of chemical pollutants in diseased individuals. During 12-15 September and 12-13 December 2007, crocodiles were captured and examined for ocular disease and sampled to determine environmental contaminant accumulation. Three of 11 (27.3%) crocodiles captured (all males) exhibited unilateral ocular disease, primarily characterized by corneal opacity and scarring, anterior synechia, and phthisis bulbi. Multiple pollutants were detected in crocodile caudal scutes (organochlorine pesticides [OCPs] and metals), crocodile blood (OCPs), and sediments (OCPs and metals) from the Tarcoles, but no associations were found between contaminant accumulation and the incidence of eye disease. On the basis of the limited number of diseased animals examined and the potential exposure of crocodiles to pathogens and other pollutants not targeted in this study, we cannot rule out infection or chemical toxicosis as causes of the eye lesions. However, circumstantial evidence suggests that the observed ocular disease is likely the result of injury-induced trauma (and possibly secondary infection) inflicted during aggressive encounters (e.g., territorial combat) among large adult crocodiles living at relatively high densities.

  1. Conversion or conservation? Understanding wetland change in northwest Costa Rica.

    Wetlands are more threatened than any other ecosystem type, with losses exceeding 50% of their original extent worldwide. Despite the small portion of the Earth's surface that they comprise, wetlands contribute significantly to global ecosystem services. In this study, we tested the hypothesis that the location and rate of change in wetland amount in the Tempisque Basin of northwest Costa Rica is predictable from landscape setting. Our results demonstrate that a strong potential exists for developing predictive models of wetland conversion based on an understanding of wetland location and surrounding trends of land use. We found that topography was the single most important predictor of wetland conversion in this area, entraining other conversion processes, and that spatial patterns of wetland loss could consistently be predicted from landscape-level variables. Areas with highest probabilities of conversion were found in the most accessible, non-protected regions of the landscape. While Palo Verde National Park made a substantial contribution to wetland conservation, our results highlight the dependence of lower-lying protected areas on upland processes, adding a little-addressed dimension of complexity to the dialogue about protected area management. Conservation strategies aimed at reducing wetland loss in tropical habitats will benefit from careful analysis of the dominant land use system(s) at a relatively broad scale, and the subsequent development of management and policy responses that take into account dynamic opportunities and constraints in the landscape.

Es una enfermedad sistémica, de moderada a severa, producida por la infección del endotelio vascular de pequeños vasos de la mayoría de órganos y tejidos. Es la más letal de las infecciones transmitidas por garrapatas y desde su descubrimiento, hace cerca de 100 años, todavía se presenta, aunque esporádicamente, de forma persistente, y a pesar de que se cuenta con antibióticos efectivos, la mortalidad sigue siendo de mas del 10% y los pacientes requieren terapia intensiva durante la infección si esta no es diagnosticada y tratada a tiempo. En tiempo recientemente se han descrito otras especies de garrapatas que pueden transmitir rickettsias a humanos así como nuevas especies de rickettsias que pueden producir cuadros de fiebres manchadas y aunque se ha dilucidado parte de sus mecanismos patogénicos, persisten muchas dudas respecto a su virulencia.

    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.

Later, to help finance that enterprise, he founded the United Fruit Company and the Jamaican workers remained in the Province of Lim...

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

    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

    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

    Background We previously screened 400 elderly Costa Ricans for neurodegenerative disease. Those reporting occupational pesticide exposure (18%) had an increased Parkinson’s disease (PD) risk (OR 2.57, 95% CI 0.91–7.26), and worse cognition (Mini-Mental States Exam (MMSE) 24.5 versus 25.9 points, p=0.01). We subsequently measured long-lasting organochlorine pesticides (β-HCH, DDE, DDT, and dieldrin) in a sub-sample (n=89). Dieldrin and β-HCH have been linked to PD, and DDE to Alzheimer’s disease. Methods We ran regression models for MMSE and tremor-at-rest to assess associations with pesticides in 89 subjects. Results The percent of β-HCH, DDE, DDT (parent compound for DDE), and dieldrin above their limit of detection (LOD) were 100%, 93%, 75%, and 57%, respectively. Tremor-at-rest was found in 21 subjects, and the mean MMSE was 25. Those who reported occupational pesticide exposure (n=36) had more detectable dieldrin samples (p=0.005), and higher mean levels of dieldrin (p=0.01), than those not reporting exposure. Other pesticides did not differ between those with and without self-reported occupational exposure. There was a positive but non-significant trend of higher risk for tremor-at-rest with higher dieldrin (p=0.10 for linear trend). Neither DDE nor DDT showed a relationship with MMSE. However, after excluding two outliers with the lowest MMSE scores, higher DDT levels showed some modest association with lower MMSE (p=0.09 for linear trend). Conclusions Our data are limited by small sample size. However, dieldrin was high in our population, has been previously linked to PD, and could be partly responsible for the excess PD risk seen in our population. PMID:25173053

    Full Text Available The objective of this study was to check for the presence of resistance to clethodim in Poa annua populations 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 exercised good control (S population, and from another farm where clethodim 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 was 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.

Allelic frequencies and major population genetic parameters were determined for eighteen microsatellite markers. An analysis of molecular variance was also carried out and genetic distances were calculated between cattle from different regions. At the national level, a high allelic diversity was found, with an average of 14.6±1.01 observed alleles and 5.6+0.37 effective alleles per marker. Observed (Ho and expected (He heterozygosities were 0.76±0.01 and 0.81±01, respectively. Polymorphic Information Content (PIC and Coefficient of Inbreeding (FIS were 0.79±0.06 and 0.06±0.004, respectively. At the regional level, Ho ranged between 0.73±0.02 in the South Central region to 0.78±0.01 in the North Huetar region. The dendrogram showed three clearly distinct groups, Metropolitan Central and West Central regions in one group, Caribbean Huetar, South Central, Central Pacific and Chorotega regions in a second group; and North Huetar and Brunca regions in a third intermediate group. Estimates of genetic differentiation (RST were significant between regions from different groups and non-significant for regions within the same group. Genetic differences between regions are related to differential proliferation of breed groups based on their adaptability to the agro-ecological conditions and production systems prevailing in each region.

  4. The distribution of nutrients, dissolved oxygen and chlorophyll a in the upper Gulf of Nicoya, Costa Rica, a tropical estuary.

    2007-06-01

    In the Gulf of Nicoya on the Pacific Coast of Costa Rica, nutrient rich equatorial subsurface water (ESW) is upwelled in much of the lower gulf. These offshore waters are often regarded as the major source of nutrients to the gulf. However, for most of the year, the ESW has little influence on the nutrient content of the upper gulf, which has a distinct character from the lower gulf. The upper gulf, extending 40 km north of the restriction between Puntarenas Peninsula and San Lucas Island, is bordered primarily by mangrove swamps, is less than 20 m deep, and is less saline than the lower gulf. We surveyed the upper gulf for dissolved inorganic nitrogen, phosphate, silicate, dissolved oxygen, and chlorophyll in November 2000, January and July 2001. All nutrients are more concentrated in the upper gulf during the rainy and transitional seasons than the dry season, significantly so for phosphate and silicate. Throughout the year, nutrients tend to be much more concentrated in the less saline water of the upper gulf. This trend indicates that discharge from the Tempisque River predominantly controls spatial and temporal nutrient variability in the upper gulf. However, nutrient rich ESW, upwelled offshore and mixed to form a mid-temperature intermediate water, may enter the inner gulf to provide an important secondary source of nutrients during the dry season.

    2004-07-15

    Four affected siblings in a Costa Rican family presented an aggressive polyneuropathy with widespread involvement of many visceral organs and onset during the third decade of life with rapid loss of muscle mass in the lower limbs and severe dysautonomy. The medical histories include vitreous opacity, cardiac enlargement, dermal and gastrointestinal infiltration, and autonomic dysfunction including circulatory compromise and gastrointestinal disturbances. Histological studies using Congo red stain and immunohistochemical assays with antibodies against the transthyretin (TTR) protein showed widespread deposition of amyloid in extracellular areas, including dermis and gastrointestinal lamina propia, endo- and perineural spaces, and vascular walls. A mutation search in the transthyretin (ttr) gene was performed seeking the cause of this severe form of familial amyloidotic polyneuropathy (FAP). We applied single-stranded conformational polymorphism (SSCP)-analyses followed by sequencing of the four exons of the ttr gene, revealing a point mutation in exon 3, a G to A transition that causes a Glu54Lys codon change. Western blots of plasma proteins incubated with anti-transthyretin antibodies after gel electrophoresis provided separation of wild-type and mutant TTR protein in affected family members.

    2016-01-01

    In this paper, we give a generic algorithm of the transition operators between Hermitian Young projection operators corresponding to equivalent irreducible representations of SU(N), using the compact expressions of Hermitian Young projection operators derived in a companion paper. We show that the Hermitian Young projection operators together with their transition operators constitute a fully orthogonal basis for the algebra of invariants of $V^{\\otimes m}$ that exhibits a systematically simplified multiplication table. We discuss the full algebra of invariants over $V^{\\otimes 3}$ and $V^{\\otimes 4}$ as explicit examples. In our presentation we make use of various standard concepts such as Young projection operators, Clebsch-Gordan operators, and invariants (in birdtrack notation). We tie these perspectives together and use them to shed light on each other.

    1987-07-01

    The Geochemical Atlas of the San Jose and Golfito 1:200,000-scale quadrangles, Costa Rica, was produced to help stimulate the growth of the Costa Rican mining industry and, thus, to benefit the economy of the country. As a result of the geochemical data presented in the Atlas, future exploration for metallic minerals in Costa Rica can be focused on specific areas that have the highest potential for mineralization. Stream-sediment samples were collected from drainage basins within the two quadrangles. These samples were analyzed for 50 elements and the results were displayed as computer-generated color maps. Each map shows the variation in abundance of a single element within the quadrangle. Basic statistics, geological and cultural data are included as insets in each map to assist in interpretation. In the Golfito quadrangle, the geochemical data do not clearly indicate undiscovered gold mineralization. The areas known to contain placer (alluvial) gold are heavily affected by mining activity. Statistical treatment of the geochemical data is necessary before it will be possible to determine the gold potential of this quadrangle. In San Jose quadrangle, gold and the pathfinder elements, arsenic and antimony, are indicators of the gold mineralization characteristic of the Costa Rican gold district located in the Tilaran-Montes del Aguacate Range. This work shows that high concentrations of these elements occur in samples collected downstream from active gold mines. More importantly, the high concentrations of gold, arsenic, and antimony in sediment samples from an area southeast of the known gold district suggest a previously unknown extension of the district. This postulated extension underlain by Tertiary volcanic rocks which host the gold deposits within the gold district. The geochemical data, displayed herein, also indicate that drainage basins north of Ciudad Quesada on the flanks of Volcan Platanar have high gold potential.

    2014-12-01

    Salt is a major determinant of population blood pressure levels. Salt intake in Costa Rica is above levels required for good health. With an increasing number of Costa Ricans visiting fast food restaurants, it is likely that fast-food is contributing to daily salt intake. Salt content data from seven popular fast food chains in Costa Rica were collected in January 2013. Products were classified into 10 categories. Mean salt content was compared between chains and categories. Statistical analysis was performed using Welch ANOVA and Tukey-Kramer HSD tests. Significant differences were found between companies; Subway products had lowest mean salt content (0.97 g/100 g; p food categories. Salt content in sandwiches ranged from 0.5 to 2.1 g/100 g. The high levels and wide variation in salt content of fast food products in Costa Rica suggest that salt reduction is likely to be technically feasible in many cases. With an increasing number of consumers purchasing fast foods, even small improvements in salt levels could produce important health gains.

    1996-12-01

    During the first cruise leg with the RV Victor Hensen to the Pacific coast of Costa Rica in December 1993 (end of the rainy season) the crustacean fauna found in the demersal collections revealed an unexpected species richness and biomass. The Crustacea collections were analyzed qualitatively and quantitatively during the fourth leg (February 1994, dry season) in the three study areas Golfo Dulce (GD), Bahía Coronado in the Sierpe-Térraba-estuary (ST) and Golfo de Nicoya (GN). Qualitative data were available for comparison from the first leg in december 1993. A total of 24 beamtrawl and ten ottertrawl sample collections were done on an area of 860.000 m2 yielding a total of 119 species with a biomass of 37.8 kg (10275 specimens). Despite the smaller area covered by the beamtrawl, it collected a higher number of species and more biomass than the ottertrawl due to the smaller mesh size (0.8 cm). Judging from the shape of the species -per-area-curves, the crustacean fauna appeared as representatively sampled for the study area. As compared with the GN (biomass 0.36 g +/- 0.26, SR = 97) and the ST (0.41 g +/- 0.27, SR = 59) and according to the results of the log-series-plots constructed from the abundance data, the GD seems to be a depauperated area with significantly lower biomass (0.05 g +/- 0.07) and species richness (45 sp.). No crustaceans were found in the center of the deep basin of the GD put parts of the interior gulf with adjacent mangrove areas seem to be important as nursery area for some commercially important penaeid shrimp species. The ST-estuary revealed the highest mean species number per station in the whole study area, but the GN had the highest total number of species. Biomass seems to be regularly distributed and not depth-depending within the GN, while species abundance varies clearly, confirming previous results. In contrast, abundance and biomass correlated well in the ST. Based on the results of the multivariate analysis, seven station

    Full Text Available Combinar en forma sostenible el patrimonio histórico cultural, el desarrollo turístico y la calidad ambiental es sin duda alguna el reto que enfrentan muchas comunidades latinoamericanas que en años recientes han hecho toda clase de esfuerzos por atraer turistas. 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.

    Full Text Available La Costa Maya est une région côtière du sud du Quintana Roo (Mexique, proche de l'îlet Ambergris au Bélize. 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. On ignore à quel niveau les nouvelles infrastructures tels l'aéroport international de Tulum qui propose un itinéraire de Chetumal à la plage et le nouveau complexe hôtelier à Xahuayxel, stimuleront la Costa Maya mexicaine créant peut-être une autoroute côtière reliée à San Pedro au Bélize.The Costa Maya is a vernacular coastal region of southeastern Quintana Roo (Mexico and adjacent Ambergris Cay, Belize.  As Mexico’s Caribbean coast suffered many growth pains associated with mass tourism development in Cancun and along the Riviera Maya, the Costa Maya by contrast was projected for more sustainable development including low-density housing and

    Deshon, Heather Rene

    Most large (MW > 7.0) underthrusting earthquakes nucleate along a shallow region of unstable frictional stability on or near the subducting plate interface termed the seismogenic zone. The studies presented here investigate along-strike spatial and temporal variability in microseismicity and seismic velocity and provide spatial constraints on the updip and downdip limits of microseismicity within the Middle America subduction offshore western Costa Rica. All chapters utilize data recorded by the Costa Rica Seismogenic Zone Experiment (CRSEIZE), a collaborative seismic and geodetic study undertaken from September 1999--June 2001 to better understand subduction zone behavior near the Osa and Nicoya Peninsulas, Costa Rica. Chapter 1 serves as a broad introduction to the thesis while Chapter 2 provides an overview of Costa Rica seismicity, the CRSEIZE experiment setup, data processing, and data quality. Chapter 3 discusses simultaneous inversion for 1D P- and S-wave velocity models, station corrections, and hypocenter parameters for both the Nicoya and Osa experiments and presents a refined location for the continental Moho in northern Costa Rica. Chapter 4 presents absolute and relative relocations of ˜300 aftershocks of the 1999 Quepos, Costa Rica, underthrusting earthquake and analyzes seismogenic zone structure offshore central Costa Rica during a period of increased seismicity rate. Subduction of highly disrupted seafloor north of the Osa Peninsula has established a set of conditions that presently limit the seismogenic zone to be between 10--35 km below sea level, 30--95 km from the trench axis. Chapter 5 presents high resolution earthquake locations and P-wave and P-wave/S-wave 3D velocity models for the locked Nicoya Peninsula segment of the Middle America subduction zone calculated using an iterative, damped least squares local tomography method. In the southern Nicoya Peninsula, microseismicity along the plate interface extends from 12--26 km depth, 73

    Two computational approaches to study plausible conformations of biological molecules and the transitions between them are presented and discussed. The first approach is a new search algorithm which enhances the sampling of alternative conformers using a mean field approximation. It is argued and demonstrated that the mean field approximation has a small effect on the location of the minima. The method is a combination of the LES protocol (Locally Enhanced Sampling) and simulated annealing. The LES method was used in the past to study the diffusion pathways of ligands from buried active sites in myoglobin and leghemoglobin to the exterior of the protein. The present formulation of LES and its implementation in a Molecular Dynamics program is described. An application for side chain placement in a tetrapeptide is presented. The computational effort associated with conformational searches using LES grows only linearly with the number of degrees of freedom, whereas in the exact case the computational effort grows exponentially. Such saving is of course associated with a mean field approximation. The second branch of studies pertains to the calculation of reaction paths in large and flexible biological systems. An extensive mapping of minima and barriers for two different tetrapeptides is calculated from the known minima and barriers of alanine tetrapeptide which we calculated recently.1 The tetrapeptides are useful models for the formation of secondary structure elements since they are the shortest possible polymers of this type which can still form a complete helical turn. The tetrapeptides are isobutyryl-val(χ1=60)-ala-ala and isobutyryl-val(χ1=-60)-ala-ala. Properties of the hundreds of minima and of the hundreds intervening barriers are discussed. Estimates for thermal transition times between the many conformers (and times to explore the complete phase space) are calculated and compared. It is suggested that the most significant effect of the side chain size is

En Costa Rica rige desde el 13 de diciembre de 1994 la "Ley de Bienestar de los Animales", pero sin embargo esta Ley deja sin definir importantes aspectos técnicos y de control del uso de los animales de experimentación. Debería de existir un manual de referencia, aprobado por una Autoridad Nacional competente, sobre el manejo y uso de animales de laboratorio y, principalmente, cursos sobre ética y técnica del uso de este reactivo biológico dirigido a los investigadores. La legislación sobre el uso de animales de laboratorio en algunos países como los Estdos Unidos, Inglaterra, Canadá, Suecia, Colombia, Australia y Alemania son más estrictas. Sin embargo en Costa Rica desde 1992 se presentó un proyecto de Ley que pretendía regular los derechos de los animales proclamados en la Declaración Universal de los derechos del animal, pero en la actualidad se encuentra archivado. Sin embargo en 1993 fue publicado en la Gaceta No 242 del 20 de diciembre de 1993 el proyecto "Ley de Bienestar y Etiología de los Animales", que no tiene ningún antecedente directo en realción al uso de animales de laboratorio en Costa Rica pero desarrolla el marco jurídico de la Declaración Universal de los Derechos del Animal, proclamada por las Ligas Nacionales afiliadas a la ONU y aun no suscrita por Costa Rica.Laboratory animals are used like analogs to the human diseases, just as much in gnotobiology, dental investigation, embriology and teratology, oncology, gerontology, cardiovascular

Sin embargo desde finales de 1999 se ha observado un aumento drástico en el número de personas intoxicadas, especialmente en la costa pacífica del país. En Costa Rica existe gran desconocimiento acerca del problema. Debido al impacto que producen los fenómenos FAN en la salud pública, el turismo local y el ecosistema, es necesario describir las especies tóxicas y sus toxinas para tomar las medidas adecuadas de control y prevención. Métodos: Se realizaron muestreos de agua en varios sectores de la costa pacífica de nuestro país, con el objetivo de detectar las especies de microalgas potencialmente tóxicas y nocivas, y se interrogó a los pescadores locales. La identificación de las especies se realizó morfológicamente mediante microscopía de luz y electrónica de rastreo. Los hallazgos se compararon con la bibliografía y se propuso el potencial tóxico de estas microalgas, así como los métodos de análisis toxicológico, y la sintomatología de los afectados. Resultados: Observamos en Costa Rica un aumento en número de especies de microalgas productoras de FAN. Se reportaron las especies tóxicas productoras de FAN descritas por varios autores y las encontradas en este estudio. En algunas muestras de floraciones algales hemos encontrado bacterias grandes intracelulares, de forma bacilar, principalmente dentro del dinoflagelado Prorocentrum micans.

    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

    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

    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 measurements of potential eruption hazards, as well as of volcano processes.

    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.

    Carranza, María

    2007-08-01

    Based on the case of Rosa, a nine-year-old girl who was denied a therapeutic abortion, this article analyzes the role played by the social in medical practice. For that purpose, it compares the different application of two similar pieces of legislation in Costa Rica, where both the practice of abortion and sterilization are restricted to the protection of health and life by the Penal Code. As a concept subject to interpretation, a broad conception of medical necessity could enable an ample use of the therapeutic exception and a liberal use of both surgeries. The practice of therapeutic sterilization has been generalized in Costa Rica and has become the legitimate way to distribute contraceptive sterilization. In contrast, therapeutic abortion is very rarely practiced. The analysis carried out proposes that it is the difference in social acceptance of abortion and sterilization that explains the different use that doctors, as gatekeepers of social morality, make of medical necessity.

    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.

    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.

    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.

    Little is known about the factors associated with asthma, allergic rhinitis, and eczema in Latin American countries. We investigated the relation between potential risk factors and current wheezing, allergic rhinitis, and eczema among 208 Costa Rican children aged 10-13 years participating in phase II of the International Study of Asthma and Allergies in Childhood (ISAAC). The geometric mean ( +/- SD) serum total IgE level of children with current wheezing was significantly higher than that of children without current wheezing (533.8 +/- 5.2 vs. 144.7 +/- 6.0 IU/mL, P eczema and STR to dog dander were associated with eczema in the child. The interaction between familial factors and lifestyle changes resulting from social reforms implemented 60 years ago may explain the high prevalence of atopic diseases in Costa Rica.

    The African Spur tortoise, Geochelone sulcata, has been introduced to Costa Rica. A total of 31 tortoises were measured for 26 gross morphometry parameters. All individuals measured were inmature, aged from 5 to 34 months, and were born in captivity in La Garita de Alajuela, Costa Rica. Mean straight carapace length was 83.1 mm, mean straight plastron length was 68.3 mm and mean maximum height was 46.2 mm. All the measurements were correlated, except tail length and cloacal distance. Weight had the highest positive allometry coefficient. All the variables were joined in two Principal Components; tail length and cloacal distance in Factor 2 and the rest of them in Factor 1. Lack of correlation among tail measures and the other variables as well as their inclusion in a different Factor could be related with an incipient development of sexual dimorphism characters.

    Full Text Available The article presents an analysis of the economic policy of energy in Costa Rica and of the exceptional role which the Costa Rican Institute of Electricity (ICE – the company responsible for the provision of energy and telecommunications – has historically held in shaping the national identity. The basic assumption is that the institutional profile of the ICE, as well as its evolution and impact on development have been shaped by very specific political, social and economic conditions which are difficult to replicate in other developing countries in the South. It is specifically argued that, since its foundation in 1949, ICE has become one of the cornerstones of a peculiar kind of welfare state and of a solidarity model for development which is listed among the most advanced in the world in terms of social progress.

  15. Interseismic megathrust coupling beneath the Nicoya Peninsula, Costa Rica, from the joint inversion of InSAR and GPS data

    2015-05-01

    The Nicoya Peninsula, Costa Rica, was struck by a long-anticipated and gap-filling Mw 7.6 earthquake in 2012. To study interseismic strain accumulation on the megathrust beneath the Nicoya Peninsula, we present an improved interseismic coupling model by integrating interferometric synthetic aperture radar (InSAR) and GPS data. Our model reveals three strongly coupled patches. The first strongly coupled patch locates beneath the Nicoya Peninsula and ruptured during the 2012 earthquake. The second strongly coupled patch locates offshore the central Nicoya Peninsula and remained largely unbroken. However, this region is close to and possibly intermingled with shallow slow slip and tremor, suggesting that accumulated strain in this region may be released both seismically and aseismically. The third strongly coupled patch offshore of the southeastern end of Nicoya overlaps part of the coseismic rupture of the 1990 Mw 7.0 Nicoya Gulf earthquake, indicating that significant strain has re-accumulated since this event. Incorporating InSAR data provides a more refined interseismic coupling model than using GPS alone and allows for a more reliable comparison with local seismic and aseismic activities. This comparison indicates that strongly locked regions during the interseismic stage are the loci of coseismic slip, and deep slow slip and low-frequency earthquakes occur in regions of low coupling or transition zones from low to high coupling, while shallow slow slip and tremor commingle with strongly coupled regions. Our study demonstrates that InSAR data can be used to recover small long-wavelength deformation signals with refined resolution in challenging subduction zone environments when integrated with GPS observations.

  16. Turmoil at Turrialba Volcano (Costa Rica): Degassing and eruptive processes inferred from high-frequency gas monitoring.

    Eruptive activity at Turrialba Volcano (Costa Rica) has escalated significantly since 2014, causing airport and school closures in the capital city of San José. Whether or not new magma is involved in the current unrest seems probable but remains a matter of debate as ash deposits are dominated by hydrothermal material. Here we use high-frequency gas monitoring to track the behavior of the volcano between 2014 and 2015 and to decipher magmatic versus hydrothermal contributions to the eruptions. Pulses of deeply derived CO2-rich gas (CO2/Stotal > 4.5) precede explosive activity, providing a clear precursor to eruptive periods that occurs up to 2 weeks before eruptions, which are accompanied by shallowly derived sulfur-rich magmatic gas emissions. Degassing modeling suggests that the deep magmatic reservoir is ~8-10 km deep, whereas the shallow magmatic gas source is at ~3-5 km. Two cycles of degassing and eruption are observed, each attributed to pulses of magma ascending through the deep reservoir to shallow crustal levels. The magmatic degassing signals were overprinted by a fluid contribution from the shallow hydrothermal system, modifying the gas compositions, contributing volatiles to the emissions, and reflecting complex processes of scrubbing, displacement, and volatilization. H2S/SO2 varies over 2 orders of magnitude through the monitoring period and demonstrates that the first eruptive episode involved hydrothermal gases, whereas the second did not. Massive degassing (>3000 T/d SO2 and H2S/SO2 > 1) followed, suggesting boiling off of the hydrothermal system. The gas emissions show a remarkable shift to purely magmatic composition (H2S/SO2 < 0.05) during the second eruptive period, reflecting the depletion of the hydrothermal system or the establishment of high-temperature conduits bypassing remnant hydrothermal reservoirs, and the transition from phreatic to phreatomagmatic eruptive activity.

    Full Text Available From January to July 1995, a market trial was conducted in Costa Rica with the fresh water fish species. Colossoma macropomum, commonly named “tambaqui”. About 1200 fish with an average weight of 800g were obtained from the fish culture station of the Universidad Nacional near La Rita, Guápiles. About 20 fish were delivered each Monday initially to three and later to each of four fishdealers in Limón, Guápiles, San José and Heredia. The shopkeepers purchased the fish at a price of $1.40/kg, covering all production and transport costs, and sold it for $1.97/kg. The motivations of the consumers for purchasing the fish were: curiosity, low price, good taste and recommendations by the shopkeepers. Most of the participants appreciated the taste, meat texture, freshness, colour and appearance very much. Some repondents criticized the amount of intramuscular spines in the fish. Eighty nine percent of the consumers intended to purchase more of the fish and 38% preferred this fish species above all other species. There was no effect (p > 0.05 of gender, householdsize or income level on the responses of the costumers. Chinese costumers were the only group discernible in the survey. Almost all participants thought tambaqui could get a good market position in Costa Rica. This trial shows that the price can be increased a little without losing much customers, but promotion would be necessary to get the product more known among the Costa Rican Population. The production of tambaqui could meet part of the demand for low priced fish in Costa Rica.

Later, to help finance that enterprise, he founded the United Fruit Company and the Jamaican workers remained in the Province of Limon to plant bananas. Their English-based Limonese Creole language has remained extant in spite of many government attempts to eradicate it, most likely because it acts, among other elements, as an identity marker for its people.

    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.

  11. Does Eco-Certification Have Environmental Benefits? Organic Coffee in Costa Rica

    2010-01-01

    Eco-certification of coffee, timber and other high-value agricultural commodities is increasingly widespread. In principle, it can improve commodity producers’ environmental performance, even in countries where state regulation is weak. However, evidence needed to evaluate this hypothesis is virtually nonexistent. To help fill this gap, we use detailed farm-level data to analyze the environmental impacts of organic coffee certification in central Costa Rica. We use propensity score matching t...

    On a three hundred swine sera sample collected from a Municipal Slaughter house and a Research Laboratory at the Ministerio de Agricultura y Ganadería a 26% of positivity against T. gondii was found using the carbon immunoassay. A relationship between the age and swine race are made. The epidemiological significance of this findings are discussed focused mainly on the role of swine meat as a source of human infection in Costa Rica.

    Nanotubes are generally not perfectly straight cylinders and the local curvature can influence transport properties. As shown by da Costa [1], charged particles moving on a curved surface experience an effective potential which modifies their dynamics. In this paper, we solve a one-electron Schrödinger equation in a distorted nanotube with open boundary conditions. We find that the deformations may open bandgaps suggesting their use in the design of nanotube- based electronic devices.

    The aim of this study was to document the presence of Rickettsia spp. in ticks parasitizing wild birds in Costa Rica. Birds were trapped at seven locations in Costa Rica during 2004, 2009, and 2010; then visually examined for the presence of ticks. Ticks were identified, and part of them was tested individually for the presence of Rickettsia spp. by polymerase chain reaction (PCR) using primers targeting fragments of the rickettsial genes gltA and ompA. PCR products were DNA-sequenced and analyzed in BLAST to determine similarities with previously reported rickettsial agents. A total of 1878 birds were examined, from which 163 birds (9%) were infested with 388 ticks of the genera Amblyomma and Ixodes. The following Amblyomma (in decreasing order of abundance) were found in immature stages (larvae and nymphs): Amblyomma longirostre, Amblyomma calcaratum, Amblyomma coelebs, Amblyomma sabanerae, Amblyomma varium, Amblyomma maculatum, and Amblyomma ovale. Ixodes ticks were represented by Ixodes minor and two unclassified species, designated here as Ixodes sp. genotype I, and Ixodes sp. genotype II. Twelve of 24 tested A. longirostre ticks were found to be infected with 'Candidatus Rickettsia amblyommii', and 2 of 4 A. sabanerae were found to be infected with Rickettsia bellii. Eight of 10 larval Ixodes minor were infected with an endosymbiont (a novel Rickettsia sp. agent) genetically related to the Ixodes scapularis endosymbiont. No rickettsial DNA was found in A. calcaratum, A. coelebs, A. maculatum, A. ovale, A. varium, Ixodes sp. I, and Ixodes sp. II. We report the occurrence of I. minor in Costa Rica for the first time and a number of new bird host-tick associations. Moreover, 'Candidatus R. amblyommii' and R. bellii were found in A. longirostre and A. sabanerae, respectively, in Costa Rica for the first time.

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

  8. Export-led growth as a determinant of social development in Costa Rica.

    Lundahl, M

    1991-01-01

    Costa Rica has put considerable effort into the development of education, health care, housing and social security. In order to be sustainable, this process requires that the output of such sectors as agriculture and manufacturing expands over time. The article examines the growth of the Costa Rican economy in a long run perspective, with an emphasis on foreign trade policy. The fate of the Costa Rican economy has been highly dependent on the exports of primary products, mainly coffee and bananas, for more than a century. This, however, has created a very vulnerable economy. As a result, during the 1960s, a new development strategy emerged: production of manufactures for the Central American Common Market (CACM). At the end of the 1970s, the prices of traditional export fell and the CACM more or less collapsed. The Central American economies were thrown into an acute crisis, aggravated by faculty domestic economic policies, which also jeopardized social development. This necessitated a stabilization effort on the one hand, and the development of a new trade strategy--promotion of non-traditional exports--on the other. It would appear that both efforts have been successful, although not without difficulties.

  9. The Neutral State: A Genealogy of Ecosystem Service Payments in Costa Rica

    2015-01-01

    Full Text Available Using the case of Costa Rica, this paper examines how ′carbon′ became an identifiable problem for that state. We trace how, during the 1980s, rationalities of financialisation and security arose in this country that allowed for Payments for Ecosystem Services (PES to emerge as an economic and political mechanism. Our central thesis is: this period initiated a government project of securing a viable future for the nation′s resources by linking them to global financial markets and international trade. This project of achieving resource security through economic circulation introduced new financial logics into forest management, as well as new modes of calculating the value and extent of the forest. These ways of framing resources found expression in the nation′s PES programme that is now central to the state′s goal of achieving carbon neutrality. Today, Costa Rica′s carbon flows are becoming territorialised as part of the nation′s atmosphere, biomass, people, and economy. This paper shows how carbon′s territorialisation did not begin with a concern for the climate, nor did it occur through diffusion of global climate policy to Costa Rica. Instead, carbon′s rise can be traced to locally specific ways of coping with the problem of resource security.

    In the agroexport zone of Los Santos Zone in Costa Rica, coffee is harvested by migrant labor. Most migrants are from Panama and Nicaragua. We describe migrants' housing- and service-related health determinants, with analyses of ethnicity, nationality and geography. We used interviews, observation-based assessments, and the Geographic Information System to assess a population of 8,783 seasonal migrants and 1,099 temporary dwellings at a total of 520 farms during 2004-2005. We identified determinants of poor health including widespread deficiencies in the quality of grower-provided dwellings, geographical isolation, crowding, lack of radio and television, and deficient toilets and cooking facilities. The indigenous and non-Costa Ricans shared the poorest conditions. Reluctance to use mainstream public health services was widespread, especially among foreign and indigenous migrants and the geographically isolated. Post-study, researchers organized workshops for audiences including workers, coffee producers, public officials and service providers. Topics have included migration, preventive health and hygiene, and child labor. This work was successful in convincing Costa Rican social security authorities to implement reforms that improve access to and quality of health care for the migrants. Special projects on ergonomics, psychosocial health hazards, and water quality, as well as a literacy program, are ongoing.

  12. Sub-Nyquist sampling and detection in Costas coded pulse compression radars

    2016-12-01

    Modern pulse compression radar involves digital signal processing of high bandwidth pulses modulated with different coding schemes. One of the limiting factors in the radar's design to achieve desired target range and resolution is the need of high rate analog-to-digital (A/D) conversion fulfilling the Nyquist sampling criteria. The high sampling rates necessitate huge storage capacity, more power consumption, and extra processing requirement. We introduce a new approach to sample wideband radar waveform modulated with Costas sequence at a sub-Nyquist rate based upon the concept of compressive sensing (CS). Sub-Nyquist measurements of Costas sequence waveform are performed in an analog-to-information (A/I) converter based upon random demodulation replacing traditional A/D converter. The novel work presents an 8-order Costas coded waveform with sub-Nyquist sampling and its reconstruction. The reconstructed waveform is compared with the conventionally sampled signal and depicts high-quality signal recovery from sub-Nyquist sampled signal. Furthermore, performance of CS-based detections after reconstruction are evaluated in terms of receiver operating characteristic (ROC) curves and compared with conventional Nyquist-rate matched filtering scheme.

    This paper tries to determine the origin of springs on the Costa Verde beach, located in the district of Barranco, Miraflores and Magdalena, province of Lima, Peru. These springs emerge near the shoreline, from the lower layers of a 80 meter high cliff. They have survived the process of urbanization of agricultural land, started in the early 70, which decreased the water table aquifer of Lima, and wiped the water leaks from the cliffs. To identify the source of the springs, isotopic, physical, chemical and bacteriological analysis was carried out for samples from five springs. The isotopic concentrations in waters from Costa Verde springs are depleted compared to those obtained for Lima aquifer waters, which is recharged by infiltration of the Rimac River. The measured values of those concentrations suggest that water from the Costa Verde springs should come from a direct recharge in the upper and middle basin, due to infiltration of rainfall or the river at an altitude of about 3600 m.

    The IAS region is characterized by climate features of unique nature, one of them is the Mid-Summer Drought (MSD) or "veranillo", an atmospheric feature rarely observed in other tropical regions. On the Pacific slope of Central America, the precipitation annual cycle is characterized by two rainfall maxima in June and September-October, an extended dry season from November to May, and a secondary precipitation minima during July-August (MSD). Three daily gauge stations records, e.g. La Argentina, Fabio Baudrit and Juan Santamaria, located in the Central Valley of Costa Rica were studied to characterize the MSD from 1937 to 2010. Among the aspects considered are the MSD duration, intensity, timing and seasonal predictability. The modulation of these aspects by climate variability sources as Equatorial Eastern Pacific and Tropical North Atlantic was lately explored, including their interannual and decadal variability. The MSD signal strongly impact social and economic life in the region like energy and the agriculture sector. Additionally, the Central Valley of Costa Rica hosts most of the Costa Rican population with the higher level of exposure and vulnerability to hydro-meteorological hazards.

    Maintaining genetic diversity is crucial for the survival and management of threatened and endangered species. In this study, we analyzed genetic diversity and population genetic structure at neutral loci in American crocodiles, Crocodylus acutus, from several areas (Parque Nacional Marino Las Baulas, Parque Nacional Santa Rosa, Parque Nacional Palo Verde, Rio Tarcoles, and Osa Conservation Area) in Pacific Costa Rica. We genotyped 184 individuals at nine microsatellite loci to describe the genetic diversity and conservation genetics between and among populations. No population was at Hardy-Weinberg Equilibrium (HWE) over all loci tested and a small to moderate amount of inbreeding was present. Populations along the Pacific coast had an average heterozygosity of 0.572 across all loci. All populations were significantly differentiated from each other with both FST and RST measures of population differentiation with a greater degree of molecular variance (81%) found within populations. Our results suggest C. acutus populations in Pacific Costa Rica were not panmictic with moderate levels of genetic diversity. An effective management plan that maintains the connectivity between clusters is critical to the success of C. acutus in Pacific Costa Rica.

    A total of 45 native Costa Rican tree species are threatened or in danger of extinction, but the Convention on International Trade Endangered Species (CITES) includes only eight of these in its Appendices. However, the identification of other species based on their wood anatomy is limited. The present study objective was to describe and to compare wood anatomy and fluorescence activity in some endangered or threatened species of Costa Rica. A total of 45 (22 endangered and 23 threatened with extinction) wood samples of these species, from the xylaria of the Instituto Tecnológico de Costa Rica and the Forest Products Laboratory in Madison, Wisconsin, were examined. Surface fluorescence was positive in eight species, water extract fluorescence was positive in six species and ethanol extract fluorescence was positive in 24 species. Almost all species were diffuse porous except for occasional (Cedrela odorata, C. fissilis, Cordia gerascanthus) or regular (C. salvadorensis and C. tonduzii) semi-ring porosity. A dendritic vessel arrangement was found in Sideroxylon capari, and pores were solitary in Guaiacum sanctum and Vantanea barbourii. Vessel element length was shortest in Guaiacum sanctum and longest in Humiriastrum guianensis, Minquartia guianensis and Vantanea barbourii.

    A significant amount of the global terrestrial biomass is found in tropical forests, and soil respiration is a vital part of its carbon cycling. However, data on soil trace gas flux rates in the tropics are sparse, especially from previously disturbed regions. To expand the database on carbon cycling in the tropics, this study examined soil flux rate and its variability for CO2 and CH4 in a secondary premontane wet forest south of Arenal Volcano in Costa Rica. Data were collected over a six-week period in June and July 2011 during the transition from dry to wet season. Trace gas sampling was performed at three sub-canopy sites of different elevations. The soil is of volcanic origin with a low bulk density, likely an Andisol. An average KCl pH of 4.8 indicates exchangeable aluminum is present, and a NaF pH>11 indicates the soil is dominated by short-range order minerals. Ten-inch diameter PVC rings were used as static flux chambers without soil collars. To find soil CO2 efflux rates, a battery-powered LICOR 840A CO2-H2O Gas Analyzer was used to take measurements in the field, logging CO2 concentration every ten seconds. Additionally, six, 10-mL Nylon syringes were filled with gas samples at 0, 1, 7, 14, 21, and 28 minutes after closing the chambers. These samples were analyzed the same day with a SRI 8610 Gas Chromatograph for concentrations of CO2 and CH4. The average CO2 efflux calculated was 1.7±0.8E-2 g/m2/min, and did not differ between the applied analytical methods. Soil respiration depended strongly on soil moisture, with decreasing efflux rates at higher water-filled pore space values. An annual soil respiration rate of 8.5E3 g/m2/yr was estimated by applying the observed relationship between soil moisture and CO2 efflux to annual soil moisture measurements. The relatively high respiration rates could be caused by the high soil moisture and low soil bulk density, providing optimal conditions for microbial respiration. Several diurnal sampling periods at

  2. Exploring why Costa Rica outperforms the United States in life expectancy: A tale of two inequality gradients.

    Mortality in the United States is 18% higher than in Costa Rica among adult men and 10% higher among middle-aged women, despite the several times higher income and health expenditures of the United States. This comparison simultaneously shows the potential for substantially lowering mortality in other middle-income countries and highlights the United States' poor health performance. The United States' underperformance is strongly linked to its much steeper socioeconomic (SES) gradients in health. Although the highest SES quartile in the United States has better mortality than the highest quartile in Costa Rica, US mortality in its lowest quartile is markedly worse than in Costa Rica's lowest quartile, providing powerful evidence that the US health inequality patterns are not inevitable. High SES-mortality gradients in the United States are apparent in all broad cause-of-death groups, but Costa Rica's overall mortality advantage can be explained largely by two causes of death: lung cancer and heart disease. Lung cancer mortality in the United States is four times higher among men and six times higher among women compared with Costa Rica. Mortality by heart disease is 54% and 12% higher in the United States than in Costa Rica for men and women, respectively. SES gradients for heart disease and diabetes mortality are also much steeper in the United States. These patterns may be partly explained by much steeper SES gradients in the United States compared with Costa Rica for behavioral and medical risk factors such as smoking, obesity, lack of health insurance, and uncontrolled dysglycemia and hypertension.

    PyTransit implements optimized versions of the Giménez and Mandel & Agol transit models for exoplanet transit light-curves. The two models are implemented natively in Fortran with OpenMP parallelization, and are accessed by an object-oriented python interface. PyTransit facilitates the analysis of photometric time series of exoplanet transits consisting of hundreds of thousands of data points, and of multipassband transit light curves from spectrophotometric observations. It offers efficient model evaluation for multicolour observations and transmission spectroscopy, built-in supersampling to account for extended exposure times, and routines to calculate the projected planet-to-star distance for circular and eccentric orbits, transit durations, and more.

    In the last thirty years significant changes to protect the environment have been introduced in the judicial, administrative and social systems. Costa Rica is a well known international model in the field of sustainable development, and here I present a proposal for adding environmental gaurantees to the Costa Rican Constitution. One of the most important changes in the Costa Rican judicial system has been the introduction of an environmental amendment in the Constitution (Article 50). However, it is still fundamental to introduce a Title of Environmental Guarantees in the Constitution of Costa Rica, with these components: first, the State, the public and the private sector have the duty of defending the right to a safe environment; second, public domain over environmental issues, and third, the use of the environment should be regulated by scientific and technical knowledge. If current efforts succeed, Costa Rica will be the first country in the world to include Environmental Guarantees in its Constitution. This would be an example to other nations.

    The participation of Hydro-Quebec International in the construction and development of the Rio Lajas hydroelectric project in Costa Rica was described. The 10 MW Rio Lajas hydroelectric station in Costa Rica is expected to go into operation in September of 1998. The station is owned by the HRL consortium, which is composed of Hydro-Quebec International and Corporacion Superior. Construction of the station was contracted out to SEH Constructora SA, a company composed of the Costarican contractor Saret and two companies from Quebec; Entreprises Bon Conseil and Hydro-Mecanique. The station comprises two horizontal-axis Francis turbines. Turbines and alternators were respectively supplied by Bouvier and GEC Alsthom, two French manufacturers. Considerable attention was given to the control of the Rio Lajas river, whose discharge can vary by as much as 100 times in the steep volcanic terrains. Approximately 15 Hydro-Quebec employees were delegated to Costa Rica to oversee various stages of the project.

    2009-10-01

    Full Text Available Wind turbines in the Altamont Pass Wind Resource Area (Alameda/Contra Costa Counties, California, USA generate about 730 GWh of electricity annually, but have been killing thousands of birds each year, including >2,000 raptors and hundreds of burrowing owls. We have developed collision hazard maps and hazard ratings of wind turbines to guide relocation of existing wind turbines and careful repowering to modern turbines to reduce burrowing owl fatalities principally, and other birds secondarily. Burrowing owls selected burrow sites lower on slopes and on smaller, shallower slopes than represented by the average 10 × 10 m2 grid cell among 187,908 grid cells sampled from 2,281,169 grid cells comprising a digital elevation model (DEM of the study area. Fuzzy logic and discriminant function analysis produced likelihood surfaces encompassing most burrowing owl burrows within a fraction of the study area, and the former corresponded with burrowing owl fatalities and the latter with other raptor fatalities. Our ratings of wind turbine hazard were more predictive of burrowing owl fatalities, but would be more difficult to implement. Careful repowering to modern wind turbines would most reduce fatalities of burrowing owls and other birds while adding about 1,000 GWh annually toward California’s 33% Renewable Portfolio Standard.

    The awareness of the problem of avian fatalities at large scale wind energy developments first emerged in the late 1980`s at the Altamont Pass Wind Resource Area (WRA) in Central California. Observations of dead raptors at the Altamont Pass WRA triggered concern on the part of regulatory agencies, environmental/conservation groups, resource agencies, and wind and electric utility industries. This led the California Energy Commission staff, along with the planning departments of Alameda, Contra Costa, and Solano counties, to commission a study of bird mortality at the Altamont Pass WRA. In addition to the Altamont Pass WRA, other studies and observations have established that windplants kill birds. Depending upon the specific factors, this may or may not be a serious problem. The current level of scrutiny and caution exhibited during the permitting of a new windplant development in the United States results in costly delays and studies. This is occurring during a highly competitive period for electrical production companies in the USA. Clarification of the bird fatality issue is needed to bring it into perspective. This means standardizing metrics, defining terms, and recommending methods to be used in addressing or studying wind energy/bird interactions.

    Objective Outcomes from the Women's Health Initiative have demonstrated adverse effects associated with hormone therapy (HT), and have prioritized the need to develop new alternative treatments for the management of menopause and osteoporosis. To this end, we have been investigating natural herbal medicines used by Costa Rican women to manage menopausal symptoms. Design Seventeen plant species were collected and extracted in Costa Rica. To establish possible mechanisms of action, and determine their potential future use for menopause or osteoporosis, the estrogenic activities of the herbal extracts were investigated in an estrogen reporter gene ERβ-CALUX® assay in U2-OS cells, and in reporter and endogenous gene assays in MCF-7 cells. Results Six of the plant extracts bound to the estrogen receptors. Four of the six extracts stimulated reporter gene expression in the ERβ-CALUX® assay. All six extracts modulated expression of endogenous genes in MCF-7 cells, with four extracts acting as estrogen agonists and two extracts, Pimenta dioica and Smilax domingensis, acting as partial agonist/antagonists by enhancing E2-stimulated pS2 mRNA expression, but reducing E2-stimulated PR and PTGES mRNA expression. Both P. dioica and S. domingensis induced a 2ERE-luciferase reporter gene in transient transfected MCF-7 cells, which was inhibited by the ER antagonist ICI 182780. Conclusions This work presents a plausible mechanism of action for many of the herbal medicines used by Costa Rican women to treat menopausal symptoms. However, it further suggests that studies of safety and efficacy are needed before these herbs should be used as alternative therapies to HT. PMID:19424091

    Full Text Available This research paper aims to show the panorama and scope of the current existing sex education practices carried out by the Costa Rican public universities. It analyzes different initiatives, its theoretical approaches that guide the actions, their purposes and other relevant aspects. The analysis includes secondary information as well as the point of view of students and university staff, as inputs for decision-making aimed at improving the overall education of young people. The findings take part of an exploratory research based on qualitative and quantitative methodologies based on gender and constructionism perspective. The information was gathered via the application of a questionnaire to a specific uneven stratified cluster groups, composed by 766 enrolled undergraduate students since first semester 2011 at Universidad Nacional de Costa Rica. The statistical margin of error was 1.5% and the confidence level of 95%. In addition, two focus groups with students and depth interviews with 16 persons were made. Data were tabulated with CSPRO software and analyzed using R software.  The findings suggest that Costa Rican universities recognize the importance of sex education as an essential part of overall development of students. Most of the initiatives are institutionalized; however, the lack of guidelines or policies on the subject, in most institutions, affects quality, consolidation and expansion of services. The need to strengthen and expand training activities on sexuality was identified as well. The students have a high opinion about the services offered, but few of them use these services, because they are perceived as less accessible and friendly. This paper concludes that it is a priority to maintain and strengthen existing initiatives on sexual education, so that they can effectively satisfy the needs of youth, with timely interventions and quality to enjoy a healthy and safe sexuality free from violence.

    The Gulf of Nicoya is a tectonic estuary on the Pacific coast of Costa Rica (10°N 85°W), extending about 100 km from the Tempisque river to the 500 m isobath. A dry season (December April) and a rainy season (May November) exert a significant impact on its water characteristics. The estuary is the most important fishing ground of Costa Rica, and the main Pacific ports are located within it. Coastal zone development has increased in recent years. In 1979 a research programme to study the Gulf was established at the University of Costa Rica, and foreign scientists were invited to work jointly with local experts to achieve the goals of the evaluation. More than 80 papers have been published to date, making the Gulf one of the best known tropical estuaries. The study of soft-bottom communities is an important component of this research programme. Past benthic research focused on the description of the structure of communities, while future efforts will find an unexplored field in the study of energy flow and community interactions. More than 200 species of fish, and 400 of benthic invertebrates have been identified. Future cooperative research is most welcome in larval ecology, interactions between size groups, and physiological tolerances. Considerable experience has been accumulated in the experimental manipulation of soft-bottom communities of high latitudes. This branch of ecology, however, remains little explored in the tropics. Future cooperative efforts in the Gulf of Nicoya will be established on solid ground, formed by a data base that has been improved since 1979, the existence of a marine research centre and a group of active, local scientists who have experience in working together with foreign expertise.

    Full Text Available Los Amerindos prehispánicos sudamericanos de costa pacífica se diferencian, por su conformación craneofacial, de las poblaciones de la planicie oriental, que son heterogéneas entre sí y con respecto a las transandinas. Estas últimas se comportan como perteneciendo a un único substrato, que se extiende por la franja costera, desde Tierra del Fuego hasta el Zulia Venezolano, conformando un Cordón Costero Sudpacífico (CCS. Esto ha sido corroborado por la genética, la ecología y la arqueología. La explicación más plausible hasta ahora es un efecto diferencial de flujo y deriva génica a ambos lados de la cordillera. El reciente hallazgo del mismo efecto en Centro y Norteamérica permite enlazar todo el continente hasta la costa oeste de California, en una línea continua que se corta en San Luis Obispo. Al mismo tiempo, las poblaciones de Florida y Nebraska se comportan como las de la planicie sudamericana. Se concluye que, sin desechar los mecanismos genéticos mencionados, un efecto tan extenso que sobrepasa los 14Mil kilómetros de extensión, debe ser explicado por un efecto general, tal como un proceso migratorio. Esta idea halla sustento en el modelo teórico de poblamiento temprano americano propuesto por Dixon en 2001, según el cual las migraciones americanas siguieron un trayecto Norte-Sur, aprovechando ecotonos tales como la cadena de valles situada entre los cordones montañosos y la costa pacífica. americana.

  5. Effect of hydrothermal circulation on slab dehydration for the subduction zone of Costa Rica and Nicaragua

    2016-06-01

    Dehydration of subducting oceanic plates is associated with mantle wedge melting, arc volcanism, intraslab earthquakes through dehydration embrittlement, and the flux of water into the mantle. In this study, we present two-dimensional thermal models of the Costa Rica-Nicaragua subduction zone to investigate dehydration reactions within the subducting Cocos plate. Seismic and geochemical observations indicate that the mantle wedge below Nicaragua is more hydrated than that below Costa Rica. These trends have been hypothesized to be due to a variation in either the thermal state or the hydration state of the subducting slab. Despite only small variations in plate age along strike, heat flow measurements near the deformation front reveal significantly lower heat flow offshore Nicaragua than offshore Costa Rica. These measurements are interpreted to reflect an along-strike change in the efficiency of hydrothermal circulation in the oceanic crust. We parameterize thermal models in terms of efficient and inefficient hydrothermal circulation and explore their impact on slab temperature in the context of dehydration models. Relative to models without fluid flow, efficient hydrothermal circulation reduces slab temperature by as much at 60 °C to depths of ∼75 km and increases the predicted depth of eclogitization by ∼15 km. Inefficient hydrothermal circulation has a commensurately smaller influence on slab temperatures and the depth of eclogitization. For both regions, the change in eclogitization depth better fits the observed intraslab crustal seismicity, but there is not a strong contrast in the slab thermal structure or location of the main dehydration reactions. Consistent with other studies, these results suggest that observed along-strike differences in mantle wedge hydration may be better explained by a northwestward increase in the hydration state of the Cocos plate before it is subducted.

  11. Annual Proxy Records from Tropical Cloud Forest Trees in the Monteverde Cloud Forest, Costa Rica

    The extinction of the Golden Toad (Bufo periglenes) from Costa Rica's Monteverde Cloud Forest prompted research into the causes of ecological change in the montane forests of Costa Rica. Subsequent analysis of meteorological data has suggested that warmer global surface and tropical Pacific sea surface temperatures contribute to an observed decrease in cloud cover at Monteverde. However, while recent studies may have concluded that climate change is already having an effect on cloud forest environments in Costa Rica, without the context provided by long-term climate records, it is difficult to confidently conclude that the observed ecological changes are the result of anthropogenic climate forcing, land clearance in the lowland rainforest, or natural variability in tropical climate. To address this, we develop high-resolution proxy paleoclimate records from trees without annual rings in the Monteverde Cloud Forest in Costa Rica. Calibration of an age model in these trees is a fundamental prerequisite for proxy paleoclimate reconstructions. Our approach exploits the isotopic seasonality in the δ18O of water sources (fog versus rainfall) used by trees over the course of a single year. Ocotea tenera individuals of known age and measured annual growth increments were sampled in long-term monitored plantation sites in order to test this proposed age model. High-resolution (200μm increments) stable isotope measurements on cellulose reveal distinct, coherent δ18O cycles of 6 to 10‰. The calculated growth rates derived from the isotope timeseries match those observed from basal growth increment measurements. Spatial fidelity in the age model and climate signal is examined by using multiple cores from multiple trees and multiple sites. These data support our hypothesis that annual isotope cycles in these trees can be used to provide chronological control in the absence of rings. The ability of trees to record interannual climate variability in local hydrometeorology

    Full Text Available [es] Desde la aparición del plano secuencia en forma expresiva con Citizen Kane, tal recurso se convirtió en sinónimo de modernidad cinematográfica. Ni tanto ni tan poco, el uso del plano secuencia, generalmente visible, se lo comprendió como maniera formal y toque de virtuosismo. Con el director portugués Pedro Costa, es posible entender de qué manera la crítica y teoría fílmica sobredimensionan criterios esté-ticos ante lo políticamente correcto. Con la realización de la trilogía sobre Fontainhas, Costa se ha convertido en uno de los directores excéntricos más relevantes de los últimos quince años. El recurrente uso del plano secuencia fílmico y su persuasión política a través de las imágenes discurre sobre las condiciones de producción y recepción del cine contemporáneo, poniendo énfasis en llevar a la luz del día del escenario audiovisual los sectores excluidos de su Lisboa, iniciando un periplo que comienza en Fontainhas. [en] Since the sequence shot expressively appeared with Citizen Kane, this resource became synonymous with cinematic modernity. Neither that much nor that little, the use of the sequence shot, usually visible, is understood as formal manieraand a touch of virtuosity. With the Portuguese director Pedro Costa it is possible to understand how film criticism and theory favor aesthetic criteria rather than what is politically correct. With the production of the trilogy about Fontainhas, Costa has become one of the most important marginal directors in the last fifteen years. The recurrent use of the film sequence shot and his political persuasion through images run on the conditions of production and reception of contemporary cinema, with a clear intention to bring into the light of audiovisual stage the excluded areas of Lisbon, starting a long journey that begins in Fontainhas.

    Spongberg, Alison L.

    2016-01-01

    This paper describes the initial investigation of PCB concentrations in four geographical regions (three on the Pacific and one in the Caribbean) of coastal Costa Rica: Bahia Culebra, Golfo Dulce, Golfo de Nicoya, and Limón. Overall total concentrations of PCB were low in all areas except around the port of Golfito (Golfo Dulce). Overall average concentration is 2.80 ng/g dw, with a standard deviation of 2.75. The low concentration could be due to lack of contamination or the subsequent degra...

    Antillón, F; Rodríguez, E

    1992-08-01

    In a bacteriological study on samples of bivalves, mud and surface waters from the Gulf of Nicoya, Costa Rica, 18 strains of non-01 Vibrio cholerae and 50 of V. mimicus were isolated. The samples were enriched in alkaline peptone water, and streaked on MacConkey and inositol-brilliant green bile agars. Biochemical and serological tests were used for their identification. Both species were isolated from all sampling sites (Lepanto, Jicaral and Puntarenas) with either of the two agar media, even though these were not specific for vibrios.

  12. Longer leukocyte telomere length in Costa Rica's Nicoya Peninsula: a population-based study.

    Studies in humans suggest that leukocyte telomere length may act as a marker of biological aging. We investigated whether individuals in the Nicoya region of Costa Rica, known for exceptional longevity, had longer telomere length than those in other parts of the country. After controlling for age, age squared, rurality, rainy season and gender, the mean leukocyte telomere length in Nicoya was substantially longer (81 base pairs, ptelomere length that characterizes this unique region does not appear to be explainable by traditional behavioral and biological risk factors. More detailed examination of mean leukocyte telomere length by age shows that the regional telomere length difference declines at older ages.

    Parasitoids on larvae of Caligo atreus were studied at the Estación de Biologia Tropical in Rio Macho, Cartago, Costa Rica. (1 600 masl), from March through July 2000. Fifth instar larvae of C. atreus were placed on Heliconia tortuosa Griggs var. Red Twist (Heliconiaceae) host plants at a mean temperature of 16.7 degrees C. The parasitoids obtained belong to an unidentified species of the genus Winthemia (Diptera: Tachinidae). Most flies emerge some 40 days after the eggs were laid (maximum 68 days). They make an orifice on the upper ventral part of the lepidopteran pupa. Winthemia is used commercially as biological control of cotton and banana.

  18. Pampered sons, (wo)manly men, or do-nothing machos? Costa Rican men coming of age under neoliberalism.

    Science.gov (United States)

    Mannon, Susan E; Kemp, Eagan

    2010-01-01

    This article explores how young men in Costa Rica negotiate ideas of manhood under neoliberalism. We draw on interview data involving 23 men, ages 15–35, residing in one Costa Rican city. Comparing men across three different class locations, we find diverse "markers of manhood." Our data suggest an emerging globally dominant masculine ideal among an elite class of men, a declining locally dominant masculine ideal among working-class men, and a cynical, possibly counter-cultural masculine ideal among poor men. We conclude that masculinities are not only fluid, but tied to changing economic circumstances and class structures.
