    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.

    The Republic of Costa Rica is one of the most stable and strongest countries in Central America. It is bordered by Nicaragua and Panama to the north and south and the Caribbean Sea and the Pacific ocean to the east and west and has a total land size slightly smaller than West Virginia. Costa Ricans enjoy a high life expectancy and literacy rate. As well, schools have an attendance rate of nearly 100%. The predominant ethnic group is white, and the predominant spoken language is Spanish. The work force is divided up as follows: 32% agriculture, 25% industry and commerce, 38% services and government, and 5% finance and banking. The country's climate is tropical and subtropical, and the geography of Costa Rica is composed of rugged terrain, mountains, large forest areas, some lowlands and 3 volcanic mountain ranges. The great majority of Costa Ricans are of European descent with only small numbers of the indigenous Indian population surviving today. The government of Costa Rica is democratic, holding periodic elections. The electoral process is monitored by the Supreme Electoral Tribunal. Other bodies of government include the Supreme Court of Justice and the Legislative Assembly. The National Liberation Party has been in power since 1948 and represents socialist ideals. Many factors such as: an influx of enlightened leaders and officials, flexible class lines, economic prosperity and the absence of military force have allowed Costa Rica to progress and maintain a stable economy and government amidst an unstable region. Costa Rica's relations with other countries and international organizations are excellent.

    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.

    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

    For 16 years, Costa Rica was the only country in the world that banned IVF, after it had been successfully conducted from 1995 to 2000. It also has been the only country that banned IVF based on the argument that it protects the embryo. After years of conflict, the prohibition has finally been lifted and the first baby girl was born in March 2017. This paper recounts the judicial and legal struggles Costa Rica faced in order to reestablished its IVF program. PMID:28985042

    The availability of data sets for time periods of more than a year is scarce for tropical environments. Advances in hardware and software speed-up the re-analysis of old data sets and facilitates the description of population oscillations. Using recent taxonomic literature and software we have updated and re-analized the information on crustacean diversity and population fluctuations from a set of cores collected at a mud-sand flat in the mid upper Gulf of Nicoya estuary, Pacific coast of Costa Rica (1984-1988). A total of 112 morphological species of macroinvertebrates was found, of which 29 were crustaceans. Taxonomic problems, maily with the peracarids, prevented the identification of a group of species. The abundance patterns of the crab Pinnixa valerii, the ostracod Cyprideis pacifica, and the cumacean Coricuma nicoyensis were analized with the Generalized Additive Models of the free software R. The models evidenced a variety of population oscillations during the sampling period. These oscillations probably included perturbations induced by external factors, like the strong red tide events of 1985. In additon, early on 1984 the populations might have been at an altered state due to the inpact of El Niño 1982-83. Thus, the oscillations observed during the study period departed from the expected seasonality (dry vs rainy) pattern and are thus considered atypical for this tropical estuarine tidal-flat. Crustacean diversity and population peaks were within the range of examples found in worldwide literature. However, abundances of the cumacean C. nicoyensis, an endemic species, are the highest reported for a tropical estuary. Comparative data from tropical tidal flat crustaceans continues to be scarce. Crustaceans (total vs groups) had population changes in response to the deployment of predator exclusion cages during the dry and rainy seasons of 1985. Temporal and spatial patchiness characterized the abundances of P. valeri, C. pacifica and C. nicoyenis.

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

    Full Text Available This new building is intended to house the various services of the Central Bank of Costa Rica. 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. The cables run in corrugated metal tubes, and these were kept in precise position with the aid of distance pieces.El nuevo edificio, destinado a agrupar los servicios del Banco Central de Costa Rica, está constituido por una estructura de hormigón pretensado.

    A study was carried out on the construction of indicators in biotechnology in Costa Rica as part of the project "SYMBIOSIS, Cooperative Program for the Construction of Indicators in Biotechnology adapted to Latin American and Caribbean countries, to motivate the application and transference of industrial technologies". The study focused on two units: researchers and research projects developed in Costa Rica, between 1998 and 2002. For researchers, information was collected about indicators related to sex, age, teaching activities, number of projects, academic degree, area of speciality and number of publications. For research projects we obtained information about: speciality, sector of application, duration of projects and number of researchers per project. Very interesting results include the high participation of the women in this area of investigation (54%); the low participation of young researchers (13% younger than 30), and a high proportion of the investigators that are responsible for 4 or more projects (42%). With relation to the specialities of the projects, the majority are in the category Bio-Agro (39%) whereas in Acuaculture only 1% was found. The sectors of application with the most number of projects are: Agriculture and Livestock (37%) and Human Health (35%). The main strengthts and limitatations for the development of biotechnology in Costa Rica are discussed.

    Science.gov (United States)

    1988-07-01

    Costa Rica's current financial crisis threatens to jeopardize recent gains in health indicators, especially among the low-income population. The increasing costs of developing health services and of providing social security coverage for marginal social groups can no longer be fully met by the Costa Rican government, which has steadily allocated a high percentage of the national budget to health. Given this situation, Costa Rica has appealed for international cooperation to help meet the most urgent health needs in the country. In 1985, Costa Rica's population stood at slightly under 2.6 million, with 36% aged 16 years and older. The country remains primarily rural; only 46% of the population is centered in urban areas. Costa Rica has been described as a country that maintains a strong tradition of peace and democracy. Given its political stability, Costa Rica has been the recipient of large waves of immigrants from other Central American countries in states of social political turmoil.

    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.

La diversificación agrícola que promovió Costa Rica en la década de los ochenta, permitió ampliar la oferta exportable y reducir la vulnerabilidad de la dependencia económica de productos tradicionales, como café y banano. Los retos de la economía global y el establecimiento de tratados comerciales con muchos países, hacen necesario que el país promueva en el sector agrícola la exportación con mayor valor agregado, para lo cual es necesario una modernización y reconversión productiva, ya que el modelo actual está agotado. Debemos mejorar sustancialmente los bienes y servicios que ofrecemos; para este propósito, algunos aspectos como la imagen de marca del país con tradición democrática, respeto a los derechos laborales, así como las buenas prácticas de manejo ambiental, deben publicitarse.

    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).

    This paper describes the Costa Rican health system which provides health, water and sanitation services. The health component of the system includes a public and a private sector. The public sector is dominated by the Caja Costarricense de Seguro Social (CCSS), an autonomous institution in charge of financing, purchasing and delivering most of the personal health services in Costa Rica. CCSS is financed with contributions of the affiliates, employers and the state, and manages three regimes: maternity and illness insurance, disability, old age and death insurance, and a non-contributive regime. CCSS provides services in its own facilities but also contracts with private providers. The private sector includes a broad set of services offering ambulatory and hospital care. These services are financed mostly out-of-pocket, but also with private insurance premiums. The Ministry of Health is the steward of the system, in charge of strategic planning, sanitary regulation, and research and technology development. Among the recent policy innovations we can mention the establishment of the basic teams for comprehensive health care (EBAIS), the de-concentration of hospitals and public clinics, the introduction of management agreements and the creation of the Health Boards.

    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 URRWXCal(2) 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.

The study revealed that 88% of the students showed a satisfactory level of knowledge about modem biotechnology and 79% of them reported a favorable opinion and good acceptance of this technology. Students would accept some risks associated to biotechnology if it represents an improvement to the competitiveness of Costa Rica. Some differences were detected in the opinions from students of the three universities that can be associated to the area of study. Students from social disciplines showed a higher percentage of negative acceptances to biotechnology and GMOs when their opinions were compared with those of students from life sciences and technologies.

    Full Text Available RESUMENEste trabajo utiliza datos de las Encuestas Comparativas de Fecundidad de América Latina, así como de la Encuesta Mundial de Fecundidad para estudiar las tendencias y diferenciales en el espaciamiento de los nacimientos entre las mujeres alguna vez casadas en Costa Rica durante el período 1945-1974. 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

    2004-06-01

    Full Text Available Helminth parasites of vertebrates have been studied in Costa Rica for more than 50 years. Survey work on this group of parasites is far from complete. We assembled a database with all the records of helminth parasites of wild and domestic vertebrates in Costa Rica. Information was obtained from different sources such as literature search (all published accounts and parasite collections. Here we present a checklist with a parasite-host list as well as a host-parasite list. Up to now, 303 species have been recorded, including 81 species of digeneans, 23 monogeneans, 63 cestodes, 12 acanthocephalans, and 124 nematodes. In total, 108 species of vertebrates have been studied for helminths in Costa Rica (31 species of fishes, 7 amphibians, 14 reptiles, 20 birds, and 36 mammals. This represents only 3.8% of the vertebrate fauna of Costa Rica since about 2,855 species of vertebrates occur in the country. Interestingly, 58 species (19.1 % were recorded as new species from Costa Rica and most of them are endemic to particular regions. Considering the valuable information that parasites provide because it is synergistic with all the information about the natural history of the hosts, helminth parasites of vertebrates in Costa Rica should be considered within any initiatives to accomplish the national inventory of biological resources. Starting with this compilation work, the Colección de Helmintos de Costa Rica (CHCR, hosted at the Facultad de Microbiología, Universidad de Costa Rica, has reemerged and it is our hope that it will have the standards of quality to assure that it will become the national depository of helminths in the country

  18. Glaucoma in Costa Rica: Initial approaches

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

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

    2018-01-01

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

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

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.

    With 51 100km2 of terrestrial area and 589 000km2 of national waters, Costa Rica is considered one of the countries with the greatest biodiversity. It has approximately 3.5% of the world marine species. In the last four decades, Costa Rica has done a considerable effort to create a representative system of Protected Areas (PA), mainly terrestrial. We present an assessment of the current situation of the Marine Protected Areas (MPA) in Costa Rica, through an historical analysis, and an evaluation of their distribution, coverage and management categories. Costa Rica has 166 protected areas covering 50% of the coastline; of these 20 are MPAs, classified as National Parks (90.6%), National Wildlife Refuges (6.6%), Wetlands (1.5%), Biological Reserves (1%), and one Absolute Natural Reserve (0.3%). According to IUCN criteria, 93.7% correspond to category II, 5% to IV and 1.3% to I. The marine protected surface is 5 296.5km2, corresponding to 17.5% of the territorial waters and 0.9% of the Exclusive Economic Zone. The median distance between MPAs is 22.4km in the Pacific and 32.9km along the Caribbean. The median size is close to 54km2. The main threats to MPAs are the lack of coordination between governmental agencies, limited economic resources, restricted patrolling and control, poor watershed management, and rampant coastal alteration.

  7. International politics and primary health care in Costa Rica.

    1990-01-01

    Costa Rica's internationally-renowned rural health program exemplifies the principles put forth by the 1978 Alma Ata Declaration on Primary Health Care with one exception: the government has not succeeded in achieving active community participation in health. This paper uses a historical and political-economic perspective to explain why the Costa Rican government failed in its efforts to enhance community participation after Alma Ata. International agencies have been closely involved in the design and implementation of rural health services in Costa Rica since the early 1900s, yet community participation did not figure in these programs until the mid-1970s. The demise of community participation in the early 1980s is attributed to a combination of factors including partisan conflicts, social class conflicts, interest group politics and, particularly, to the shifting priorities of international health and development agencies.

    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.

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.

    Determining Costa Ricans' behaviour patterns when using health services. The Costa Rican Health Survey was used. Central tendency, dispersion, percentages, frequencies, Ji-Square and Kruskal-Walis test measurements were analysed. Area of residence and income level were the predisposing factors in both out-patient and emergency services whereas educational level was so in terms of hospitalisation service. Health insurance status and the area of residence were the enabling factors associated with using out-patient and hospitalisation services. The need factors associated with outpatient services were the individuals' perceived state of health, having remained in bed at least until noon and suffering some chronic disease; chronic disease was associated with hospitalisation and remaining in bed when using the emergency service. Most variables postulated by Andersen and Newman's model as being determinants for using health services were present in Costa Rica. Nevertheless, the significance of its factors varied between outpatient, hospitalisation and emergency services.

  4. The Guanacaste Volcanic Arc Sliver of Northwestern Costa Rica.

    2017-05-11

    Recent studies have shown that the Nicoya Peninsula of northwestern Costa Rica is moving northwestward ~11 mm a -1 as part of a tectonic sliver. Toward the northwest in El Salvador the northern sliver boundary is marked by a dextral strike-slip fault system active since Late Pleistocene time. To the southeast there is no consensus on what constitutes the northern boundary of the sliver, although a system of active crustal faults has been described in central Costa Rica. Here we propose that the Haciendas-Chiripa fault system serves as the northeastern boundary for the sliver and that the sliver includes most of the Guanacaste volcanic arc, herein the Guanacaste Volcanic Arc Sliver. In this paper we provide constraints on the geometry and kinematics of the boundary of the Guanacaste Volcanic Arc Sliver that are timely and essential to any models aimed at resolving the driving mechanism for sliver motion. Our results are also critical for assessing geological hazards in northwestern Costa Rica.

    The presence of Arcobacter spp. in minced meat (including beef) samples has been well documented in different countries, with varying frequencies. Nevertheless, the only Latin American country reporting this bacterium in minced beef samples is Mexico, with a 28.8% frequency in 2003. Previous studies in Costa Rica have demonstrated the presence of Arcobacter species in samples taken from the poultry production chain, but still there are no studies performed in bovine meat. The aim of this study was to determine the frequency of this bacterium in 120 samples of minced beef acquired from the Central Valley region of Costa Rica and to describe the antibiotic sensitivity pattern of the isolates obtained. A total of 75 different Arcobacter strains were isolated from minced beef samples, for a final frequency of 48.3%. After species PCR identification, the strains were classified as A. butzleri (37.3%), A. cibarius (14.7%), A. thereius (12%), and Arcobacter spp. (36%). All samples were sensitive to gentamicin but were resistant to ampicillin, levofloxacin, nalidixic acid, and ciprofloxacin. The results obtained in this study show that the frequency of isolation of Arcobacter in minced beef samples is high and that there is a high resistance rate for antibiotics in common use. This suggests that Arcobacter represents a health risk for Costa Rica and that control measures should be developed to decrease its potential impact.

  6. Socioeconomic development, health interventions and mortality decline in Costa Rica.

    1991-01-01

    Costa Rica, whose life expectancy was 74 years by 1985, has reached a health level comparable to a developed country. The health achievements of this country are product of political and socioeconomic circumstances as well as of right public health policies. Until about 1970 the features of Costa Rica mortality, although somewhat better than the Latin American average, evolved in a similar way to the rest of the region. In particular, the decades of 1940s and 1950s saw dramatic improvements in life expectancy, thanks mainly to the import of low-cost, high-effectiveness health technologies. In the 1970s, however, Costa Rica departed from a regional pattern of stagnation and managed to close the gap with developed countries in terms of mortality levels. A dramatic decline in the infant mortality rate from 60 to 19 per 1,000 took place in this decade. The main determinants of this breakthrough were health interventions, notably a primary health care program, even though favorable socioeconomic conditions and a reduced fertility also played a role. Ecological data and other evidence suggest that up to three fourths of the mortality decline was accounted for contemporary improvements in public health services, with about 40 percent attributable to primary health care interventions. Furthermore, by targeting interventions on the less privileged population, these interventions had the merit of reducing geographic and socioeconomic differentials in child mortality.

    2010-01-01

    To analyze the determinants of health care utilization (visits to the doctor) in Costa Rica using an econometric approach. Data were drawn from the National Survey of Health for Costa Rica 2006. We modeled the Grossman approach to the demand for health services by using a standard negative binomial regression, and used a hurdle model for the principal-agent specification. The factors determining healthcare utilization were level of education, self-assessed health, number of declared chronic diseases and geographic region of residence. The number of outpatient visits to the doctor depends on the proxies for medical need, but we found no multivariate association between the use of outpatient visits and income or insurance status. This result suggests that there is no problem with access in the public - almost universal - Costa Rican health system. No conclusive results were obtained on the influence of the physician on the frequency of use of health care services, as postulated by the principal-agent model. Copyright © 2010 SESPAS.

    Hemoglobinopathies are hereditary autosomic recessive diseases. A total of 70 943 samples of whole blood collected by heel prick in filter paper (S&S 903) from throughout Costa Rica (October 2005-October 2006) were analyzed to detect variants of hemoglobin by the iso-electric focusing technique. Eight hundred ninety one cases presented some variant, for a frecuency of 1/79. Five cases are homozygous for hemoglobin S (sickle cell disease) and one shows the double heterozygous genotype SC. In this study the S and C variants of hemoglobin, although with some local differences, are widespread all over the country. Thus, the prevention of new cases is important through the testing of hemoglobin in the Costa Rican National Newborn Screening Program, together with a Interdisciplinary National Program of Education for the disease and carrier status (AS/AC) for patients, families and medicar personnel. This is the basis for proper genetic counseling, to improve treatment and to reduce morbi-mortality.

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

    Full Text Available Resumen. La Universidad de Costa Rica en Tránsito es un artículo que pretende dar cuenta del tránsito que ha iniciado la institución en su camino hacia la transdisciplinariedad. Se presenta, en primera instancia, un contexto histórico y referentes teóricos que apuntan a que la Universidad en el Siglo XXI debe iniciar un tránsito, por una parte, de regreso a reflejar el significado de su origen: UNIVERSUS-A-UM (“todo”, “entero”, “universal” superando fragmentaciones y departamentalizaciones y, por otro, hacia una visión transdisciplinar, un pensamiento complejo en sintonía con las realidades biológicas, sociales y culturales del mundo en el siglo XXI. Y, ya que la transdisciplinariedad no se puede llevar a cabo más que en la acción y en la interacción con otros, se reporta sobre una serie de estrategias interconectadas que se están promoviendo Universidad de Costa Rica para ayudar a la institución a iniciar ese tránsito.Abstract. University of Costa Rica in Transit is an article that reports on the journey the institution has started on its path towards transdisciplinarity. On one way, back to the origen: universus (all, whole, universal, overcoming fragmentation and departamentalization. On the other towards a transdisciplinary vision and complex thinking in accordance with the new biological, social and cultural realities of our world. Interactive and interrelated strategies that are currently beeing promoted to stimulate the institution towards transdisciplinarity are reported here. It is important to remember that transdisciplinarity can only be reflected in action, and in the interaction with others.

    The Purruja mangrove (Golfito, Costa Rica) has an estimated area of 70 ha. A socio-biological research was the ground to set initial goals to manage the resources and to identify the mangrove biological condition. Community participation and the local organization were key factors in developing an integrated model for the management of natural resources. Constant monitoring and institutional networks were the other two factors to manage the mangrove. The constant profesional support was a tool to facilitate the acomplishment of goals and to establish an institucional network to promote local group iniciatives for collaborative management of the Purruja mangrove.

  8. Demography and development: the lessons of Costa Rica.

    Gallagher, C F

    1980-01-01

    Focus in this discussion is on demography and development in Costa Rica. In a 15-year period, during the 1960s and the 1st years of the 1970s, Costa Rica achieved the fastest and steepest fertility decline yet recorded in Latin America. The crude birthrate dropped from a high point in 1959 of 48.3/1000 to a low of 29.9/1000 in 1973. During the same period, the death rate declined from 9.2/1000 to 5.2/1000 by 1973. Because of this, the drop in the rate of natural increase, from 3.9% a year in 1959 to 2.47% in 1973, was not quite as pronounced in percentage terms. During those same years infant mortality dropped from 74/1000 to about 45/1000. The total fertility rate declined from 7.3 children in 1960 to 5.5 in 1968 and to just above 4 children in 1973. The major thrust of the decline originated primarily in popular perception of the imbalance between an unnecessarily high birthrate and changed socioeconomic conditions toward the end of the 1950s, of which improvements in health and general social care were among the most influential. It is not so much the economic performance of Costa Rica that distinguishes it from its neighbors as its social condition. What keeps Costa Rica from being a "banana republic" is its comparatively much higher level of social indicators: newspaper circulation per capita and the amount of newsprint consumption, the extraordinary number of bookstores in San Jose, the number of physicians and hospital beds per person, the number of teachers and students enrolled at all levels of education, and its extremely low mortality rate and very high longevity. The total fertility rate appears to have entered a period of stagnation or pause, with virtually no decline since 1974 and even a slight increase since 1976. In the 5-year period since 1973, the decline through 1978 amounted to only 5%. In the preceding 1968-73 period it wasmore than 26%. The number of births/1000 women in the 15-19 year old age group remains constant and is comparatively very

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

    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 aim of this study was to address the hypothesis that Amerindian ancestry is associated with extended longevity in the admixed population of Nicoya, Costa Rica. The Nicoya Peninsula of Costa Rica has been considered a "longevity island," particularly for males. We estimated Amerindian ancestry using 464 ancestral informative markers in 20 old Nicoyans aged ≥99 years, and 20 younger Nicoyans (60-65 years). We used logistic regression to estimate odds ratio (OR) and 95% confidence interval (CI) of the association of Amerindian ancestry and longevity. Older Nicoyans had higher Amerindian ancestry compared to younger Nicoyans (43.3% vs 36.0%, P = .04). Each 10% increase of Amerindian ancestry was associated with more than twice the odds of being long-lived (OR = 2.32, 95% CI = 1.03-5.25). To our knowledge, this is the first time that ancestry is implicated as a likely determinant of extended longevity. Amerindian-specific alleles may protect against early mortality. The identification of these protective alleles should be the focus of future studies. © 2017 Wiley Periodicals, Inc.

To identify factors associated with susceptibility, tobacco use and addiction in young people from 13 to 15 years of age, to determine conditions of risk and identify possible correlates to the development of public policies on smoking in Costa Rica. Materials and methods. Information available from the four rounds of the Global Youth Tobacco Survey (GYTS Costa Rica was used. It was based on a sample size of 11 540 youngsters from public and private schools. Indicators of interest and logistic regression models for smoking, susceptibility and addiction were estimated. Results. The prevalence of current consumption shows a significant decrease over the 14 years of the study (17.3% in 1999 and 5.0% in 2013 and, to a lesser intensity, in the index of smoking susceptibility (19.3% in 1999 and 12.4% in 2013. The proportion of young people with addiction has shown a significant increase in the same period. Conclusions. The conditions that explained the significant reduction in smoking prevalence and less susceptibility must be maintained and deepened to achieve full compliance of the MPower measures.

Data were obtained by sampling nine transects along the coast and observations done by skin diving between September and November of 2002. This reef consist of 10.5 hectares, where 13 species of corals, 39 of macroalgae, two of seagrasses, two of zoantids, one anemone, one corallimorpharian, and one sponge were identified. Life coral coverage (16%), was higher than in other years (5% for 1985, and 13.2% for 1995), and death coral coverage was very low (0.2%). Macroalgae have the highest coverage (59%), particularly brown algae with a patchy distribution of Sargassum and Padina. Laurencia brongniartii (Rhodophyta) is added to the list of marine flora of Costa Rica. The Punta Cocles reef works as a refuge for organisms, because there are no towns or river mouths nearby, and because of the coast formation. The refuge character is enhanced by the environmental conscience of the people that live close to the reef and help to protect the environment.

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

    Brucellosis has been an endemic disease of cattle and humans in Costa Rica since the beginning of XX century. However, brucellosis in sheep, goats, pigs, water buffaloes, horses and cetaceans, has not been reported in the country. We have performed a brucellosis survey in these host mammal species, from 1999–2016. In addition, we have documented the number of human brucellosis reported cases, from 2003–2016. The brucellosis seroprevalence in goat and sheep herds was 0.98% and 0.7% respectively, with no Brucella isolation. Antibodies against Brucella were not detected in feral or domestic pigs. Likewise, brucellosis seroprevalence in horse and water buffalo farms was estimated in 6.5% and 21.7%, respectively, with no Brucella isolation. Six cetacean species showed positive reactions against Brucella antigens, and B. ceti was isolated in 70% (n = 29) of striped dolphins (Stenella coeruleoalba). A steady increase in the diagnosis of human brucellosis cases was observed. Taking into account the prevalence of brucellosis in the various host mammals of Costa Rica, different measures are recommended. PMID:28793352

    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.

  6. Perspective View with Landsat Overlay, San Jose, Costa Rica

    2002-01-01

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

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

    2010-11-01

    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.

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

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

    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

    Programming activities for the control of venereal diseases implies certain difficulties in Latin American countries owing to the lack of basic information and resources. It is perhaps for this reason that such programs have so far failed to achieve an adequate epidemiological impact. In late 1975, a new program was set up in Costa Rica with the following objectives: 1) reducing the incidence of venereal diseases; 2) detecting cases at an early stage in order to begin treatment; 3) developing a far-reaching hygiene education program; 4) establishing appropriate epidemiological surveillance machinery, including border-area programs; 5) integrating control activities with the general health services; 6) training personnel; and 7) carrying out research. Among the activities planned for the attainment of the aforementioned objectives was the detection of cases by means of voluntary presentation; surveillance of contacts; serological testing of pregnant women, blood donors, and applicants for health care identity cards, and other types of examination. Outpatient treatment was planned for all cases detected. Where epidemiological surveillance was concerned, it was proposed that improvements be made in morbidity report procedures, data analysis, and border-area programs. Plans were also made for integrating control activities into the basic health services and for reviewing the existing legislation with a view to expediting the implementation of the program. Steps taken to that end included the establishment of a more effective coordination of such activities with the Costa Rican Social Security Institute, an entity which attends the health needs of 80% of the population; a follow-up program for cases detected in the hospitals included in the program, and preparation of a flow diagram to be used for that purpose by such institutions. Other aspects considered were the distribution of treatment manuals, and information on epidemiological interview methods and laboratory

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

    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 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. Copyright © 2014 The Authors. Published by Elsevier Ltd..

Un estudio basado en 915 encuestas, 312 a visitantes de origen local y 603 a visitantes de origen extranjero fue realizado en Honduras, Nicaragua y Costa Rica, con el fin de determinar la brecha en satisfacción de los visitantes con la infraestructura, los servicios y las opciones recreativas, utilizando una forma modificada del modelo de brecha basado en la teoría de las expectativas-desconfirmacion. El estudio encontró que había diferencias y semejanzas significativas al nivel de 95% de probabilidad entre las caracterizas socio-demográficas y los niveles de satisfacción de los visitantes locales y extranjeros a los diferentes parques y entre los visitantes locales y extranjeros en cada parque. Modelos estandarizados fueron identificados para cada parque en cada categoría de visitante los cuales permitieron identificar aquellas variables que más influenciaban la brecha en satisfacción. El material anterior permitió además identificar aquellas áreas más importantes a las cuales se les deberían asignar recursos financieros para mejorar en el corto plazo los niveles de satisfacción de los visitantes.

    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.

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

    To examine whether total physical activity or activity patterns are associated with metabolic syndrome and its components. Participants include 1994 controls from a case-control study of non-fatal myocardial infarction in Costa Rica (1994-2004). Physical activity was assessed via self-administered questionnaire and patterns were identified using principal components analysis. Metabolic syndrome was assessed via blood samples and anthropometry measurements from in-home study visits. Prevalence ratios (PRs) and 95% confidence intervals (CIs) were calculated using log binomial regression. Adjusted least squares means of metabolic syndrome components were calculated by quintile of total activity and pattern scores. Four activity patterns were identified: rest/sleep, agricultural, light indoor activity, and manual labor. Total activity was not associated with metabolic syndrome. Metabolic syndrome prevalence was 20% lower in participants with the highest scores on the agricultural job pattern compared to those with the lowest (PR: 0.80, 95% CI: 0.68-0.94). Higher total activity was associated with lower triglycerides and lower HDL cholesterol. Higher scores on each pattern were inversely associated with metabolic syndrome components, particularly waist circumference and fasting blood glucose. Patterns or types of physical activity may be more strongly associated with metabolic syndrome and its components than total activity levels. Copyright © 2014 Elsevier Inc. All rights reserved.

    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.

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

    The case of Nicaraguan migrants in Costa Rica is emblematic of the issues that immigration generates in host countries. Undocumented Nicaraguan women seeking maternal care constitute a key challenge to the universal coverage of Costa Rica's health system. Can the long-standing commitment to universality, solidarity and equality expressed in the legislation be translated into practice? Discourses of health professionals in Costa Rica reveal a contradiction between merit and prejudice in prenatal and delivery care. Here, I present qualitative research based on semi-structured interviews with physicians and nurses at a Costa Rican National Hospital. The data show that migrant women, rejected from primary care, do find help in emergency services, but not without difficulties, as they must engage in individual negotiations centred on their bodies. The discourses of health providers reflect an ambivalence between the perceived undeservingness of undocumented migrant women and the medical realisation that two lives are at risk. While the foetus often evokes compassion, the mother commonly provokes repression, as specific and shifting rationalities reflect new moral regimes that are applied to this population. Women are perceived as being 'illegal', 'immoral' and 'irrational', and the baby, although legally Costa Rican due to jus solis policy, embodies 'the other'. Ultimately, otherness frames perceptions of deservingness of maternal care for undocumented migrant women in Costa Rica.

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

    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

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.

Se confirmó el diagnóstico clínico inicial en la mayoría de los casos de distrofia miotónica, pero en los casos con retardo mental, más de la mitad de los análisis resultaron negativos para la amplificación en el gen FMR1, específica de FRAXA. La razón principal para esto podría ser el cuadro clínico muy sutil que muestran los niños afectados antes de la pubertad. Los únicos métodos disponibles para prevenir estas discapacidades por el momento son, el tamizaje en cascada, el consejo genético y el aborto selectivo. De los cuales, el último no se puede llevar a cabo según las leyes vigentes en Costa Rica.

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

The aim of this work is to evaluate the levels of ultraviolet solar radiation (UV using solar radiation maps designed for the territory of Costa Rica created with the software Surfer 8. The data of UV radiation – utilized in the creation of the maps – were predicted in eighty-three geographical locations by an atmospheric spectral model, which is physically established, this model utilizes as necessary input data: the date and hour, identifying place by the latitude, length and height of the land above sea level, the value of the vertical column of the ozone, the superficial albedo and the atmospheric turbidity parameters. The estimation differs in a 3% with the experimentation data made in situ. The model estimate ultraviolet radiation under clear skies conditions; this is the maximum possible energy which is obtained in each locality. This is important at the moment to evaluate the harmful effects for the human health can cause the maximum intensity in this important band of the solar spectrum. Among the most noticeable results can be mentioned an increase of 23%  with the altitudes, among the lower places (sea level and higher places (hills and mountains. It was also found an increment greater that 27% between the months of fewer solar radiation (December and greater solar radiation (Apri. This theme is of special interest due to the growing number of people that displace during different times of the year to altitudes greater than 2000 m in activities relating to the tourism, recreation and work. In this case these people receive important increments in the levels of ultraviolet solar radiation in clear sky conditions.

    The mollusks in Manuel Antonio National Park on the central section of the Pacific coast of Costa Rica were studied along thirty-six transects done perpendicular to the shore, and by random sampling of subtidal environments, beaches and mangrove forest. Seventy-four species of mollusks belonging to three classes and 40 families were found: 63 gastropods, 9 bivalves and 2 chitons, during this study in 1995. Of these, 16 species were found only as empty shells (11) or inhabited by hermit crabs (5). Forty-eight species were found at only one locality. Half the species were found at one site, Puerto Escondido. The most diverse habitat was the low rocky intertidal zone. Nodilittorina modesta was present in 34 transects and Nerita scabricosta in 30. Nodilittorina aspera had the highest density of mollusks in the transects. Only four transects did not clustered into the four main groups. The species composition of one cluster of transects is associated with a boulder substrate, while another cluster of transects associates with site. Two clusters were not associated to any of the factors recorded. Some species were present in previous studies but absent in 1995, while others were absent in the previous studies but found in 1995. For example, Siphonaria gigas was present in 1995 in many transects with a relatively high density, but absent in 1962, probably due to human predation before the establishment of the park. Including this study, a total of 97 species of mollusks in three classes and 45 families have been reported from Manuel Antonio National Park. Sixty-nine species are new reports for the area: 53 gastropods, 14 bivalves and 2 chitons. There are probably more species of mollusks at Manuel Antonio National Park, than the 97 reported here, because some areas have not been adequately sampled (e.g., deep environments) and many micro-mollusks could not be identified.

    Paleomagnetic results from globally distributed lava flows have been collected and analyzed under the time-averaged field initiative (TAFI), a multi-institutional collaboration started in 1996 and designed to improve the geographic and temporal coverage of the 0-5 Ma paleomagnetic database for studying both the time-averaged field and its very long-term secular variations. Paleomagnetic samples were collected from 35 volcanic units, either lava flows or ignimbrites, in Costa Rica in December 1998 and February 2000 from the Cordilleras Central and Guanacaste, the underlying Canas, Liberia and Bagaces formations and from Volcano Arenal. Age estimates range from approximately 40 ka to slightly over 6 Ma. Although initial results from these sites were used in a global synthesis of TAFI data by Johnson et al. (2008), a full description of methodology was not presented. This paper documents the definitive collection of results comprising 28 paleomagnetic directions (24 normal, 4 reversed), with enhanced precision and new geological interpretations, adding two paleointensity estimates and 19 correlated 40Ar/39Ar radiometric ages. The average field direction is consistent with that of a geocentric axial dipole and dispersion of virtual geomagnetic poles (17.3 ± 4.6°) is in general agreement with predictions from several statistical paleosecular variation models. Paleointensity estimates from two sites give an average field strength of 26.3 μT and a virtual axial dipole moment of 65 ZAm2. The definitive results provide a useful augmentation of the global database for the longer term goal of developing new statistical descriptions of paleomagnetic field behavior.

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

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.

    Crime, violence, and insecurity are among the most important social topics in contemporary Costa Rica. These three issues play a central role in the media, politics, and everyday life, and the impression has emerged that security has changed for the worse and that society is now threatened permanently. However, crime statistics do not support this perception. The paper thus asks why violence and crime generate such huge fear in society. The thesis is that the Costa Rican national identity - w...

    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.

    This study describes the dynamics of adolescent childbearing of Nicaraguan-born and Costa Rican-born adolescents in Costa Rica and examines the association between socio-demographic factors and adolescent childbearing in the country. We studied Nicaraguan-born and Costa Rican adolescents using the data of the 2000 Census. Multivariate logistic regression was used to analyze the association between country of origin and adolescent childbearing, while controlling for socio-demographic factors (age, education, union, urbanization and poverty). 26% of Nicaraguan-born migrants and 9.5% of Costa Ricans had given birth during adolescence. The migrants' increased odds of pregnancy decreased from 3.34 (CI 3.21, 3.48) to 1.88 (CI 1.79, 1.97) when controlling for socio-demographic factors. Age, low educational attainment, urban residence, poverty and union were all significant predictors of adolescent pregnancy. Nicaraguan-born status is associated with adolescent childbearing in Costa Rica. Further research is needed to understand what factors, other than socio-demographic indicators, contribute to the differing prevalence of adolescent childbearing in Costa Rica.

    2001-01-01

    A study of several loci blood groups (ABO, Diego, Duffy, Kell, Kidd, Lewis, Lutheran, MNSs, P, Rhesus and Secretor), and Hp serum protein was carried out on a sample of 2,196 unrelated Costa Rican individuals of both sexes. Data was classified and analyzed according to geographic regions. Gene frequencies and the goodness of fit to Hardy-Weinberg equilibrium were estimated by the maximum likelihood method. A geographic structuring was observed in the Costa Rican population. All the regions of Costa Rica show higher heterozigosity values than the ones observed in the indigenous Costa Rican groups, but similar or slightly higher than the ones observed in the Spanish populations. The genetic distance analysis evidenced that the regions of Costa Rica group close to each other in intermediate positions between the Amerindians and the Spanish, fact that is coherent with the statement that attributes a intermediate origin to the general population of Costa Rica. The data contradicts the idea that the Central region has a radically different population than the rest of the country. The outcome of these markers revealed poor values of exclusion probability in forensic and paternity cases, which confirms the importance of their replacement for DNA markers in the outlines of human identification of judicial investigation systems. These results are similar to other studies made in Latin American populations.

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

    Science.gov (United States)

    Campo-Engelstein, Lisa; Meagher, Karen

    2011-08-01

    A dominant cultural narrative within Costa Rica describes Costa Ricans not only as different from their Central American neighbours, but it also exalts them as better: specifically, as more white, peaceful, egalitarian and democratic. This notion of Costa Rican exceptionalism played a key role in the creation of their health care system, which is based on the four core principles of equity, universality, solidarity and obligation. While the political justification and design of the current health care system does, in part, realize this ideal, we argue that the narrative of Costa Rican exceptionalism prevents the full actualization of these principles by marginalizing and excluding disadvantaged groups, especially indigenous and black citizens and the substantial Nicaraguan minority. We offer three suggestions to mitigate the self-undermining effects of the dominant national narrative: 1) encouragement and development of counternarratives; 2) support of an emerging field of Costa Rican bioethics; and 3) decoupling health and national successes. © 2011 Blackwell Publishing Ltd.

  9. The fertility plateau in Costa Rica: a review of causes and remedies.

    Holl, K D; Daily, G C; Ehrlich, P R

    1993-01-01

    Costa Rica achieved a substantial reduction in its overall fertility rate in a very short period of time. The halving of the fertility rate which occurred in less than ten years in Costa Rica transpired over the course of 100 years in France and 170 in Sweden. The level of contraceptive use in Costa Rica is twice that in other Central American nations. The authors summarize the recent demographic history of Costa Rica and review factors influencing its remarkable fertility decline. They then discuss possible explanations for the ensuing fertility plateau and conclude by suggesting strategies for affecting a further decrease in fertility rates. With regard to the reasons for the fertility plateau, cultural factors, socioeconomic factors, declining government commitment and family planning services, education, and the Church are considered. To reduce the level of fertility even further, the authors recommend that the government adopt a clear population policy which could serve as a basis for other changes such as increased support of family planning programs, improvements in the educational system, increased women's status and employment opportunities, and extensive education in schools and through the mass media on the socioeconomic and environmental effects of overpopulation. It is important to increase Costa Ricans' understanding of the negative impacts of continued population growth and the role of individual family planning decisions in that growth.

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

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

    1982-04-01

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

  11. Food niche overlap among neotropical frugivorous bats in Costa Rica

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

  6. Is the Central Valley of Costa Rica a genetic isolate?

    Directory of Open Access Journals (Sweden)

    Bernal Morera

    2004-09-01

    Full Text Available In the last decade, the Costa Rican Central Valley population (CRCV, has received considerable scientific attention, attributed in part to a particularly interesting population structure. Two different and contradictory explanations have emerged: (1 An European-Amerindian-African admixed population, with some regional genetic heterocigosity and moderate degrees of consanguinity, similar to other Latin-American populations. (2 A genetic isolate, with a recent founder effect of European origin, genetically homogeneous, with a high inter-marriage rate, and with a high degree of consanguinity. Extensive civil and religious documentation, since the settlement of the current population, allows wide genealogy and isonymy studies useful in the analysis of both hypotheses. This paper reviews temporal and spatial aspects of endogamy and consanguinity in the CRCV as a key to understand population history. The average inbreeding coefficients ?(alpha between 1860 and 1969 show a general decrease within time. The consanguinity in the CRCV population is not homogeneous, and it is related to a variable geographic pattern. Results indicate that the endogamy frequencies are high but in general it was not correlated with alpha ?values. The general tendency shows a consanguinity decrease in time, and from rural to urban communities, repeating the tendencies observed in other countries with the same degree of development, and follows the general Western World tendency. Few human areas or communities in the world can be considered true genetic isolates. As shown, during last century, the CRCV population has had consanguinity values that definitively do not match those of true genetic isolates. A clear knowledge of the Costa Rican population genetic structure is needed to explain the origin of genetic diseases and its implications to the health system. Rev. Biol. Trop. 52(3: 629-644.

    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

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

    Directory of Open Access Journals (Sweden)

    Jing Li

    2014-12-01

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

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 Esta es una breve descripción de lo que ha sido el desarrollo de la citogenética humana en Costa Rica, la situación actual y las expectativas a corto plazo. Esta ciencia- arte nació hace poco más de cuarenta años en la Facultad de Medicina de la Universidad de Costa Rica. Actualmente se desarrolla como un servicio diagnóstico-asistencial en el Hospital Nacional de Niños "Dr. Carlos Sáenz Herrera" y con un componente adicional de investigación en el Instituto de Investigaciones en Salud de la misma universidad. Los ensayos que se ofrecen a la población son los cariotipos en sangre periférica y en médula ósea, el diagnóstico prenatal citogenético en muestras de líquido amniótico y de sangre fetal y con menos frecuencia en biopsias de piel.Past, present and future of cytogenetics in Costa Rica. This is an overview of the past, present and future of human Cytogenetics in Costa Rica. It started in 1965 at the University of Costa Rica where it has been developed slowly but steadily. There is only one overloaded clinical cytogenetic laboratory in the social security system. The tests currently performed are peripheral blood and blood marrow karyotypes, prenatal cytogenetic diagnosis (amniotic fluid and fetal blood and less frequently skin biopsies. The task now is to standardize molecular cytogenetic techniques, we are actually working with PRINS in order to study submicroscopic subtelomeric rearrangements associated with mental retardation and other microdeletion syndromes as well.

This is an historical overview of prenatal cytogenetic diagnosis in Costa Rica. It started in 1984 at the Institute for Health Research of the University of Costa Rica. This is the only fetal cytogenetic diagnosis facility in the country and serves social security as well as private patients. Perinatologists send amniotic fluid and fetal blood samples from high risk pregnancies, mainly due to abnormal ultrasound assessment, sonographic markers of aneuploidy and advanced maternal age. Second and third trimester diagnosis allows the development of coping strategies for the families of affected fetuses, since pregnancy interruption is not permitted. Normal fetal cytogenetic results provide reassurance to the parents. Rev. Biol. Trop. 52(3: 545-549. Epub 2004 Dic 15.

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

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

    Lücke, O. H.; Linkimer, L.

    2013-12-01

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

  10. Dying with AIDS in Costa Rica. Access to care and treatment.

    Science.gov (United States)

    1997-01-01

    Costa Rica, with a population of 3 million people, has approximately 1200 cumulative diagnosed cases of AIDS. 70% of AIDS cases in the country have been among gay men. About 500 people with AIDS (PWA) are still alive and it is estimated that just as many people may be asymptomatic carriers of HIV. At the cost of $800-1000 per month per person, approximately 700,000 people, mostly in the US and Europe, are being treated with combination drug therapy capable of managing AIDS as a fairly curable chronic illness. However, most people in Costa Rica, where the per capita annual income is $2500, cannot afford to pay for such therapy. Arguing that the drugs are too expensive, the government has not approved any of the retroviral medications for general use in its socialized medical system which otherwise guarantees appropriate medical treatment to its citizens. The pharmaceutical companies which distribute the medications in Costa Rica, Roche and Bristol Meyers, refuse to provide patients with either free or significantly discounted drugs. The author discusses social discrimination against gay people in Costa Rica and describes attempts made to negotiate drug supplies for PWA with the government and pharmaceutical companies.

  11. Men's narratives of vasectomy: rearticulating masculinity and contraceptive responsibility in San José, Costa Rica.

    Science.gov (United States)

    Pomales, Tony O

    2013-03-01

    This article interrogates the modes by which cultural constructions of male contraceptive use emerge in Costa Rica by analyzing men's narratives of vasectomy. Drawing on ethnographic research data, I examine men's contraceptive decision making and perspectives on vasectomy and specify the ways they work through their vasectomy to rearticulate the relationship between masculinity and contraceptive responsibility and tensions in an emerging Costa Rican social modernity. Following Oudshoorn's (2003) analysis on male contraceptive research, this article highlights contraceptive technologies and men's narratives of these technologies as key sites for examining gender politics in contemporary societies and the materialization of new social orders. In the discussion, I argue that the men's narratives examined here potentiate creation of an "alternative technosociality" (Oudshoorn 2003) in Costa Rica, in which men taking contraceptive responsibility does not constitute performing a subordinate masculinity, but simply another way of acting as men. © 2013 by the American Anthropological Association.

    Full Text Available Costa Rica se ha convertido en un país multicultural. Muchas personas han migrado a él en busca de mejores condiciones de vida. La mayoría de estas personas son nicaragüenses, quienes conforman alrededor de tres cuartas partes del grupo total inmigrante en el país. En el año 2007, se realizó un proyecto de investigación en la Escuela de Educación Física y Deportes de la Universidad de Costa Rica que tuvo la finalidad de estudiar cómo se recreaba esta población antes y, especialmente, después de la inmigración a Costa Rica. La investigación fue cualitativa, fenomenológica, e incluyó 13 personas nicaragüenses residentes en el Área Metropolitana. La información que se presenta en este artículo fue recolectada mediante entrevistas y observaciones de la participación en una actividad recreativa. Los datos fueron analizados en forma individual y se triangularon. Los resultados generales indican que: (1 la población investigada realizaba once tipos de actividades recreativas en Nicaragua, entre semana y fines de semana, antes de venir a Costa Rica; (2 esa misma población participaba en diez categorías de actividades recreativas en Costa Rica, entre semana y fines de semana, y (3 ese grupo percibió siete beneficios que le ofrecía la recreación.

    2014-12-01

    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 La distrofia miotónica tipo1 (DM1 y el síndrome del cromosoma X frágil (FRAXA son dos enfermedades hereditarias relativamente comunes. Ambas constituyen ejemplos de un nuevo tipo de mecanismo mutacional, llamado mutaciones inestables o dinámicas, expansión de tripletas, o amplificación del ADN. La DM1 se considera como la distrofia muscular más frecuente en los adultos y FRAXA es la principal causa de retardo mental hereditario. Este trabajo presenta resultados actualizados de un estudio prospectivo no aleatorio en pacientes clínicamente afectados, que se realiza con el objetivo de confirmar el diagnóstico con técnicas moleculares (Hibridación de Southern y reacción en cadena de la polimerasa, PCR, y llevar a cabo el tamizaje en cascada del resto de la familia para ofrecerles consejo genético adecuado. Se confirmó el diagnóstico clínico inicial en la mayoría de los casos de distrofia miotónica, pero en los casos con retardo mental, más de la mitad de los análisis resultaron negativos para la amplificación en el gen FMR1, específica de FRAXA. La razón principal para esto podría ser el cuadro clínico muy sutil que muestran los niños afectados antes de la pubertad. Los únicos métodos disponibles para prevenir estas discapacidades por el momento son, el tamizaje en cascada, el consejo genético y el aborto selectivo. De los cuales, el último no se puede llevar a cabo según las leyes vigentes en Costa Rica.Myotonic dystrophy and fragile X syndrome are two genetically determined relatively common disabilities. Both are examples of a new type of mutation mechanism called unstable or dynamic mutations, triple repeats expansions or DNA amplification. Fragile X syndrome is recognized as the main cause of hereditary mental retardation and myotonic dystrophy is considered the most common muscular dystrophy of adults. This is a prospective non randomized study of clinically affected people, in order to confirm the diagnosis with

Además, se identifican los factores que explican la demanda relativa de los depósitos bancarios según su grado de liquidez y se buscan evidencias de irreversibilidad del proceso (histéresis mediante variables de tipo “ratchet”.Como factores explicativos del fenómeno, se plantean la probable influencia de elementos institucionales y de los estímulos económicos derivados de la globalización de la economía y de los diferenciales de rendimientos financieros. Pero se sostiene también que las políticas monetaria y cambiaria han tenido efectos en el nivel de dolarización alcanzado por la economía costarricense; por una parte, la política deencajes llevada a cabo desde 1996 favoreció la constitución de depósitos en moneda extranjera (y la intermediación de esos fondos ha debido generar la expansión secundaria de esos recursos y, por otra, el ajuste cambiario siempre alcista bajo el régimen de minidevaluaciones ha estimulado la sustitución de activos.Se concluye en general que la dolarización de depósitos bancarios ha alcanzado niveles muy elevados (50% del total y la significancia de la variable “ratchet” da indicios de que el proceso es de difícil reversión por lo que es de esperar que se mantenga en el futuro la

    Full Text Available 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

    Full Text Available Objetivo: Realizar una primera aproximación a los determinantes de la utilización de consultas médicas en Costa Rica. Método: Los datos proceden de la Encuesta Nacional de Salud para Costa Rica 2006. En el análisis econométrico se utilizó un modelo binomial negativo estándar ligado al enfoque de producción de salud de Grossman y un modelo en dos partes congruente con el enfoque agente-principal. Resultados: Los factores determinantes de la utilización de consultas médicas fueron el nivel educativo, el estado de salud percibida, el número de enfermedades crónicas declaradas y la región de residencia. Conclusiones: El hecho de que las variables de necesidad de salud expliquen de forma significativa la probabilidad de contacto con las consultas médicas y que, además, no se registren diferencias significativas de utilización entre quintiles de ingreso y situación de seguro, es un resultado esperable y deseable en un sistema público solidario y casi universal como el costarricense. No se obtienen resultados concluyentes de la influencia del médico en la frecuencia de utilización de las consultas que postula el modelo de agente-principal.Objective: To analyze the determinants of health care utilization (visits to the doctor in Costa Rica using an econometric approach. Methods: Data were drawn from the National Survey of Health for Costa Rica 2006. We modeled the Grossman approach to the demand for health services by using a standard negative binomial regression, and used a hurdle model for the principal-agent specification. Results: The factors determining healthcare utilization were level of education, self-assessed health, number of declared chronic diseases and geographic region of residence. Conclusion: The number of outpatient visits to the doctor depends on the proxies for medical need, but we found no multivariate association between the use of outpatient visits and income or insurance status. This result suggests that

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

    2015-01-01

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

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

    Objective The relationship among education, psychiatric diagnoses and psychotropic medication use has been explored in the United States, but little is known about patterns in poorer countries, despite their high documented burden of mental illness. Educational gradients in diagnosis and psychotropic use were estimated in the United States and Costa Rica – a middle-income country with universal health insurance. Methods Analyses were conducted using data on older adults (ages 60+) in nationally representative surveys from each country: the 2005 U.S. Medical Expenditures Panel Survey (n=4788) and the 2005 Costa Rican Longevity and Healthy Aging Study (n=2827). Logistic regressions examined the effect of lower educational attainment, income and urban residence on diagnosis and on psychotropic medication use with and without an associated mental illness diagnosis. Results Rates of self-reported diagnoses were lower in the U.S. (12% U.S.; n=598) than in, Costa Rica (20%; n=526), but may reflect differences in survey wording. Measures of self-reported and screened depression decreased with education in both countries. Psychotropic medication use among those with diagnoses increased with education in Costa Rica only. Conclusions We find similar patterns of educational gradients in diagnosis and screening between the U.S. and Costa Rica, but different patterns of medication use by education. Differences in stigma and access to care may play an important role in explaining differences between the countries, though we did not find evidence that insurance affected educational gradients in the U.S. These analyses increase the evidence on the role of education in the use of the health care system.

    Energy Technology Data Exchange (ETDEWEB)

    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.

We analyzed Costa Rican vital records for the years 1996-2005 with negative binomial regression models to determine the relative mortality risks of Nicaraguan immigrants versus Costa Rican natives with adjustments for age, urbanization, unemployment, poverty, education, and residential segregation. Nicaraguan-born men and women had reduced mortality risks of 32% and 34% relative to their Costa Rican-born counterparts. Excess homicide mortality was found among Nicaraguan-born men [rate ratio (RR) = 1.35, 95% CI: 1.19-1.53] and women (RR = 1.41, 95% CI: 1.02-1.95). The Nicaraguan-born population had a reduced all-cause mortality risk versus Costa Rican-born people over the years 1996-2005, due to markedly lower disease mortality. Homicide is a major source of excess mortality among Nicaraguan-born immigrants versus Costa Rican natives.

    Full Text Available Utilizando datos del Registro Nacional de defunciones de los años 1996-2005 se calcularon las tasas de mortalidad estandarizadas por edad para personas nacidas en Nicaragua versus personas nacidas en Costa Rica. Así mismo, utilizando modelos de regresión binomial se determinaron los riesgos relativos de mortalidad de los inmigrantes nicaragüenses versus personas nativas de Costa Rica con ajustes por edad, urbanización, desempleo, pobreza, educación y segregación residencial. Los hombres y mujeres nacidos en Nicaragua tuvieron un riesgo reducido de mortalidad de 32% y 34% respectivamente con relación a sus contrapartes nacidas en Costa Rica. Se notó que los riesgos de mortalidad por enfermedades infecciosas, cáncer, enfermedades crónicas pulmonares, enfermedades cardiovasculares, y enfermedades crónicas del hígado eran significativamente reducidos entre los inmigrantes nacidos en Nicaragua. El exceso significativo de mortalidad por homicidios se encontró entre los hombres nacidos en Nicaragua (RT = 1,35, 95% IC: 1,19; 1,53 y en mujeres (RT = 1,41, 95% IC: 1,02; 1,95. El riesgo relativo de causas de mortalidad de origen de tipo exógeno entre los inmigrantes nicaragüenses fue más grande entre los grupos de edad joven en áreas de baja densidad de inmigrantes nicaragüenses. La población nacida en Nicaragua residiendo en Costa Rica tiene un riesgo reducido de mortalidad por causas generales versus las personas nacidas en Costa Rica en los años entre 1996-2005. Esto se debe a una mortalidad por enfermedad reducida, la cual es bastante marcada. El homicidio es un una razón de mayor mortalidad entre los inmigrantes nacidos en Nicaragua versus los nativos costarricenses. Hay una gran necesidad de llevar acabo investigaciones adicionales sobre el rol de la migración, estatus socioeconómico y comportamientos entorno a la salud para poder explicar más a fondo los patrones de mortalidad diferenciales entre los inmigrantes nicarag

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

    The projected rising prevalence of diabetes and impaired fasting glucose (IFG) in developing countries warrants careful monitoring. The aim of this study was to present the results of the Costa Rican National Cardiovascular Risk Factors Surveillance System, which provides the first national estimates of diabetes and IFG prevalence among adults in Costa Rica. A cross-sectional survey of 3653 non-institutionalized adults aged ≥20 years (87.8% response rate) following the World Health Organization STEPwise approach was built on a probabilistic sample of the non-institutionalized population during 2010. Known diabetes was defined as self-reported diagnosis, the use of insulin, or hypoglycemic oral treatment as consequence of diabetes during at least the previous 2 weeks before the survey. Unknown diabetes was defined no self-reported diabetes but with venous blood concentrations of fasting glucose >125 mg/dL determined by laboratory testing. Impaired fasting glucose was defined as fasting glucose between 100 and 125 mg/dL among those without diabetes. The prevalence of diabetes and IFG prevalence was estimated according gender, body mass index (BMI), waist circumference (WC), educational level, and physical activity level. Overall diabetes prevalence was 10.8% (9.5% known and 1.3% unknown diabetes) and IFG prevalence was 16.5%. The prevalence of known diabetes was higher among women >65 years compared with men of the same age group. Both known and unknown diabetes were significantly associated with higher BMI, increased WC, and low education level (P = 0.01). The prevalence of diabetes and IFG in Costa Rica is comparable to that in developed countries and indicates an urgent need for effective preventive interventions. © 2015 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

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.

    Aerosol pollution has become a major issue in Costa Rica because of the urban development that induces an increase in vehicle and industrial emissions. The Metropolitan area in Costa Rica is a valley ( 1,967 km2 area) with a population of 2.6 million. This area concentrates 60% of the country's total industry and 57% of its vehicle emissions. In addition, this area is impacted by biogenic emissions coming from national forests surround it and windblown dust from the Sahara Desert transported by the Trade winds. PM10 and other criteria pollutants have been measured in the past 12 years. However, those monitor stations are single points of observation and do not represent the spatial and temporal resolution that the Costa Rican national government requires for long term policy decisions and health effects assessments. This investigation uses the Weather Research and Forecasting model coupled with Chemistry version 3.7 (WRF-Chem) to forecast PM10 concentration over Costa Rica in 2013. The temporal scales take into consideration the dry, rainy, and transition seasons of the country. The spatial domain was constructed with a master domain (27 km resolution) and multiple nested-domains (9, 3, and 1 km respectively) that include the total area of Costa Rica. The meteorology data bases for this model are from the European Centre for Medium-Range Weather Forecasts (ECMWF) Interim Reanalysis (Era-Interim; Dee et al. 2011). In addition, the chemical transport model uses emissions inventories from the PREP-CHEM-SRC tool, because of the lack of an appropriate national emission inventory for this investigation. The total average of PM10 observed at the metropolitan area of Costa Rica was 26±9 μgm-3 in 2013. According to the World Health Organization, this result exceeds the PM10 standard established in the air quality guidelines (WHO 2005). The final goal of this investigation is to evaluate the chemical transport simulations with ground-level measurements from more than 10

    Full Text Available RESUMENEn este trabajo se logró conocer los criterios de clasificación empleados para definir a la población con discapacidad en los registros censales del siglo XX en Costa Rica y, por consiguiente, una aproximación a las formulaciones conceptuales para referirse al grupo en estudio. Además, se caracterizó a ese segmento poblacional a partir de diferentes variables: sexo, edad, estado civil y distribución geográfica. También se abordaron otros aspectos como fueron: alfabetismo, nivel de educación, ocupación, jefatura de hogar y vivienda. Entre los hallazgos más destacables se encuentra la permanencia, en los registros censales del siglo XX, de un concepto de discapacidad basado en la deficiencia, lo que definió los criterios de clasificación para esa población en esas fuentes. Asimismo se constató, por una parte, la asociación entre discapacidad e inequidad en esa centuria y, por la otra, la fragilidad de los vínculos de parentesco en ese grupo poblacional con respecto al conjunto de hogares de Costa Rica a fines de ese siglo. Las fuentes empleadas en esta investigación fueron los censos de población de Costa Rica del siglo XX. En el procedimiento con los datos, se llevó a cabo un análisis descriptivo de distribución de frecuencias. ABSTRACTThis research discloses the classification criteria used to define the population with disability in the twentieth century census records in Costa Rica and therefore gives an approximation of the conceptual formulations needed to refer to the examined group. Additionally, a segment of the population has been characterized by sex, age, marital status and geographical distribution. Other aspects like literacy rate, education level, occupation, head of household and housing were also dealt with. The disability concept based on deficiency, which defined the classification criteria for the population in those data sources, is among the most significant findings of this research. Furthermore

    Diversity and microstructure of quitons (Mollusca: Polyplacophora) from the Caribbean of Costa Rica. The polyplacophorans of the coral reef on the Caribbean coast of Costa Rica have been insufficiently studied. The examination of coral rubble accumulated in the shallow sublitoral waters on four collection stations in Provincia Limón revealed a higher diversity of chitons than was documented. From the country eight species were previously known: Ischnochiton erythronotus (C.B. Adams 1845); Ischnoplax pectinata (Sowerby 1840); Stenoplax boogii (Haddon 1886); S. purpurascens (C.B. Adams 1845); Acanthopleura granulata (Gmelin 1791); Chiton marmoratus Gmelin 1791; C. tuberculatus Linnaeus 1758 and Acanthochitona rhodea (Pilsbry 1893). This study added five more species that are reported here for the first time: Callistochiton portobelensis Ferreira 1976; Ischnochiton kaasi Ferreira 1987; I. pseudovirgatus Kaas 1972; Acanthochitona balesae Abbott 1954 and Cryptoconchus floridanus (Dall 1889).

    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, mean leukocyte telomere length in Nicoya was substantially longer (81 base pairs, pCosta Rica, providing evidence of a biological pathway to which this notable longevity may be related. This relationship remains unchanged (79 base pairs, p<0.05) after statistically controlling for nineteen potential biological, dietary and social and demographic mediators. Thus the difference in mean leukocyte telomere 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. PMID:23988653

    2017-04-01

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

    2004-12-01

    Parallel to a zooplankton study (1999-2000) observations were made (from an inflatable boat), on the presence of dolphins along a transect (-8 km long) on the axis of Culebra Bay (24 km2), Gulf of Papagayo, Pacific coast of Costa Rica. Dolphins were found during 20 of the 31 boat surveys conducted. The only species of cetacean found in the bay was Stenella attenuata, the spotted dolphin. These sightings were more frequent during the rainy season, particularly during the month of May of both years. The presence of S. attenuata in Culebra Bay might be associated to the abundances of fish and mollusks (their presumed prey: for example, squids), as evidenced by fishery statistics available for this zone of the Pacific coast of Costa Rica.

To determine the bacteriological quality of fishery products in the different stages from commercialization, monthly samples were taken during March 2004 and February 2006 from a Costa Rica marketing chain. Microbiological analyses were made to determine total coliforms (CT), faecal coliforms (CF), Escherichia coli (EC), aerobic total count (RTA), Salmonella sp., Staphylococcus aureus, Vibrio cholerae and Vibrio parahaemolyticus. Three body zones were analyzed: skin, belly and muscle. There were differences in the amount of CT between parts: skin had the highest counts, 11% of samples were identified as E. coli. and 2.5% of total counts were higher than the legal limit. Only 1.3% of the samples were S. aureus-positive. Salmonella sp., V. cholerae and V. parahaemolyticus were absent.

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

    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.

    Following World Health Organization recommendations set forth in the Global Framework for Immunization Monitoring and Surveillance, Costa Rica in 2009 became the first country to implement integrated vaccine-preventable disease (iVPD) surveillance, with support from the U.S. Centers for Disease Control and Prevention (CDC) and the Pan American Health Organization (PAHO). As surveillance for diseases prevented by new vaccines is integrated into existing surveillance systems, these systems could cost more than routine surveillance for VPDs targeted by the Expanded Program on Immunization. We estimate the costs associated with establishing and subsequently operating the iVPD surveillance system at a pilot site in Costa Rica. We retrospectively collected data on costs incurred by the institutions supporting iVPD surveillance during the preparatory (January 2007 through August 2009) and implementation (September 2009 through August 2010) phases of the iVPD surveillance project in Costa Rica. These data were used to estimate costs for personnel, meetings, infrastructure, office equipment and supplies, transportation, and laboratory facilities. Costs incurred by each of the collaborating institutions were also estimated. During the preparatory phase, the estimated total cost was 128,000 U.S. dollars (US$), including 64% for personnel costs. The preparatory phase was supported by CDC and PAHO. The estimated cost for 1 year of implementation was US$ 420,000, including 58% for personnel costs, 28% for laboratory costs, and 14% for meeting, infrastructure, office, and transportation costs combined. The national reference laboratory and the PAHO Costa Rica office incurred 64% of total costs, and other local institutions supporting iVPD surveillance incurred the remaining 36%. Countries planning to implement iVPD surveillance will require adequate investments in human resources, laboratories, data management, reporting, and investigation. Our findings will be valuable for

    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. Copyright © 2015 Elsevier GmbH. All rights reserved.

    2002-01-01

    Forest area figures. at a given point in time and for a given region of interest, differ considerably, affecting the calculation of deforestation rates and thus confuse the political and scientific discussion on the state and change of the resource forest. This article discusses the variation of published forest cover figures, using Costa Rica as an example. A list of published figures on the forest cover of Costa Rica from 1940 onwards is analyzed. Reasons for the differences are hypothesized and discussed. These differences are mainly in the definition of forest and forest classes included, in the type of the studies conducted (mapping and/or sampling), in the precision of the estimates, and in the information sources used. It is concluded that part of the problem is inherent in the nature of the resource 'forest'. Quality and completeness of the presentation of the forest cover estimates are a clue to their correct understanding and interpretation. The latter point being especially relevant, as forest cover data have both a technical-scientific and a political meaning and are used as relevant arguments in many discussions. In the example of Costa Rica, a general downward trend is observed up to about 1985/1990, whereas after that forest area figures are on the average at a markedly higher level. Some hypotheses for this change in the trend are discussed.

    Full Text Available 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.

    Full Text Available We describe a new vanilla species growing in sympatry with Vanilla planifolia Jacks. ex Andrews (Orchidaceae in the province of Limón, Caribbean coast of Costa Rica. The morphology of the reproductive and vegetative organs observed on vines cultivated under shade-house, the nuclear (Internal Transcribed Spacer and plastid (matK nucleotide sequences, as well as the contents of aromatic compounds measured in ripe fruits, show that this species is close to but distinct from V. planifolia. The name V. sotoarenasii M.Pignal, Azofeifa-Bolaños & Grisoni sp. nov. is proposed for this new Vanilla species endemic in Costa Rica. It is especially distinguished from V. planifolia by a reduction of about 30% of the size of the fruits and flowers, by a divergence of ITS sequences for at least two species-conserved nucleotides compared to seven other species of the V. planifolia group, and by the presence of anisic compounds and low content of phenolic compounds (including vanillin in the fruits. These results confirmed the extension of the area of distribution of V. planifolia southward to Costa Rica, where a recent speciation process occurred. Because of its particular agronomic and aromatic properties, V. sotoarenasii sp. nov. could represent a valuable biological resource for the vanilla industry.

    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. © 2015 Blackwell Verlag GmbH.

    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.

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

    Rosero-Bixby, Luis; Dow, William H

    2016-02-02

    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.

    Full Text Available In the XIX century, a mostly Afro-Jamaican linguistic minority settled down on the Caribbean coast of Costa Rica, a Spanish-speaking country. They went there to work for Minor C. Keith, an enterprising U.S. engineer who had been commissioned by the Costa Rica government to build a railroad that would join an eastern port to the Central Valley capital, San Jose. 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. But, will it survive globalization? And if so, for how long?.//En el siglo XIX un grupo compuesto en su mayoría por afro-jamaiquinos se estableció en la costa Caribe de Costa Rica, un país de habla hispana.

    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.

    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.

    Full Text Available La conducción de la política monetaria ha evolucionado junto con el desarrollo de los diferentes enfoques teóricos macroeconómicos y las enseñanzas que se han derivado de la evidencia empírica. A partir de la quiebra del Sistema de Bretton Woods todos los países tuvieron que buscar la forma de implementar y conducir su política cambiaria y monetaria en forma consistente. En ese momento, empezó un proceso de prueba y error que ha sido fundamental en la conceptualización de la política monetaria.Por mucho tiempo Estados Unidos fue quien llevó la pauta en esta materia, su máxima contribución fue deducir a la luz de la evidencia empírica que la función primordial de la política monetaria es garantizar una inflación baja y estable con el fin de crear las condiciones necesarias para lograr el máximo crecimiento económico. A pesar de esa conclusión, su estrategia muestra una discrepancia con la concepción teórica, lo cual podría estar justificada en el mandato legal que obliga a la política de la Reserva Federal a alcanzar varios objetivos macroeconómicos simultáneos, es decir, máximo crecimiento, mínima inflación y tasa de interés moderada de largo plazo.

    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.

    The purpose of this article is to share information about the Costa Rican Marine Education Programme in relation to the quality criteria for Education for Sustainable Development (ESD) Schools. We found that the application of these criteria is feasible, not only to the organisation and management of schools that are looking to become ESD Schools, but also for the analysis of different projects seeking to educate students from the perspective of sustainable development. The way in which the criteria were adapted in this case to the area of teaching and learning proved both easy and effective, following the conceptual document produced by Breiting, Mayer and Mogensen in 2005. We therefore recommend that proposals of this kind be disseminated more widely and more attention be paid to their potential to contribute to education systems. As to the Marine Education Programme, the analysis performed highlighted its pertinence and conceptual orientation, and provided an insight into the methodology applied during its constituent workshops; however, in this case, the approach adopted was not tailored in accordance with quality criteria for ESD.

    Full Text Available Recientemente, la costa del Pacífico de Costa Rica ha experimentado un aumento en magnitud y frecuencia de proliferaciones algales nocivas (PAN. La falta de datos con respecto a la dinámica de estos eventos en el área, y las especies de microalgas que los producen, son temas de mucho interés. Las PAN han producido impactos negativos en los recursos pesqueros y en la salud humana en Costa Rica. En mayo de 2002, una PAN se observó frente a las playas a lo largo del Pacífico central; además, se observó un gran número y diversidad de peces muertos. Las muestras de agua fueron recolectadas usando una red de fitoplancton y se fijaron para ser procesadas posteriormente con microscopía electrónica. Asimismo, se tomó un litro de muestra de la superficie para su posterior conteo celular. En la PAN observada, los organismos dominantes fueron la cianobacteria Trichodesmiun erythraeum, rodeada por altas concentraciones de bacterias Gram -, y el dinoflagelado Cochlodinium cf. polykrikoides. T. erythraeum, es una de las principales cianobacterias fijadoras de N2 atmosférico en aguas marinas, y se ha asociado con los eventos PAN en diversas partes del mundo, produciendo síntomas como dermatitis por contacto con la brisa marina y otras afecciones. C. cf. polykrikoides es un dinoflagelado asociado con mortalidad de peces; aunque el tipo de toxinas asociadas aún es desconocido. En un periódico nacional se reportaron 17 casos de intoxicación en humanos durante este mismo periodo de PAN, los afectados presentaron desórdenes respiratorios e irritación en los ojos. Éste es el primer informe en Costa Rica dónde se observaron cianobacterias y dinoflagelados juntos produciendo PAN.

The goal of this cohort study was to evaluate the characteristics of a group of Costa Rican breast cancer patients and their relationship with survival. Age, stage, tumor grade, immunohistochemistry, lymphovascular invasion, recurrence, and survival data on 199 Hispanic patients with breast cancer diagnosis, treated between January 2009 and May 2010, were collected from a single institution in San Jose, Costa Rica. The data were statistically analyzed for significance. Median age at diagnosis was 53 years. With a median follow-up of 46.5 months, there was an 88% overall survival rate. Thirty-seven percent of the patients (p Costa Rica. The higher proportion of triple negative tumors, advanced stage, and younger median age at diagnosis could contribute to the inferior prognostic described among Hispanic women. There may be a different distribution of tumor subtypes compared to non-Hispanic white women. Further studies are necessary to confirm such findings.

    Little is known about sensitization (defined as a positive IgE) to helminths and disease severity in patients with asthma. To examine the relationship between sensitization (defined as a positive IgE) to Ascaris lumbricoides and measures of asthma morbidity and severity in a Costa Rican population with low prevalence of parasitic infection but high prevalence of parasitic exposure. Cross-sectional study of 439 children (ages 6 to 14 years) with asthma. Linear regression and logistic regression were used for the multivariate statistical analysis. After adjustment for parental education and other covariates, sensitization to Ascaris lumbricoides was associated with having at least 1 positive skin test to allergens (odds ratio, 5.15; 95% CI, 2.36-11.21; P < .001), increased total serum IgE and eosinophils in peripheral blood, reductions in FEV(1) and FEV(1)/forced vital capacity, increased airway responsiveness and bronchodilator responsiveness, and hospitalizations for asthma in the previous year (odds ratio, 3.08; 95% CI, 1.23-7.68; P = .02). Sensitization to Ascaris lumbricoides is associated with increased severity and morbidity of asthma among children in Costa Rica. This association is likely mediated by an increased degree of atopy among children with asthma who are sensitized to Ascaris. In areas with a low prevalence of helminthiasis such as Costa Rica, Ascaris sensitization may be an important marker of severe atopy and disease morbidity in children with asthma.

    Full Text Available Treatment with the usual antimalarial drugs, have induced parasite resistance, reinforcing the need to finding natural antimalarial components that would be found on plants from the forest. Therefore, we decided to look for these components in Costa Rican plants from a protected forest area. Fresh and dry extracts of roots, bark, leaves, flowers and fruits of 25 plants from a biological reserve in Costa Rica, Reserva Biológica Alberto Manuel Brenes (REBAMB, were studied in vitro for the presence of substances with antimalarial activity. By studying the inhibition of P. berghei schizogony, we assessed the antimalarial activity of several plant extracts: Aphelandra aurantiaca, A. tridentata (Acanthaceae; Xanthosoma undipes (Araceae; Iriartea deltoidea (Arecaceae; Neurolaena lobata (Asteraceae; Senna papillosa, Pterocarpus hayessi, Lonchocarpus pentaphyllus (Fabaceae; Nectandra membranacea, Persea povedae, Cinamomum chavarrianum (Lauraceae; Hampea appendiculata (Malvaceae; Ruagea glabra, Guarea glabra (Meliaceae; Psidium guajava (Myrtaceae; Bocconia frutescens (Papaveraceae; Piper friedrichsthalii (Piperaceae; Clematis dioica (Ranunculaceae; Prunus annularis (Rosaceae; Siparuna thecaphora (Siparunaceae; Solanum arboreum, Witheringia solanácea (Solanaceae; Ticodendrum incognitum (Ticodendraceae; Heliocarpus appendiculatus (Tiliaceae and Myriocarpa longipes (Urticaceae.

The fresh extracts showed stronger activity than the dry ones. Since the plants showing the strongest antimalarial activity are very common in Central America, and some similar genera of these plants have shown positives results in South America, we considered important to present these findings for discussion.

    Full Text Available Sharks are highly vulnerable to intense and prolonged fishery extraction. This article analyzes the data on shark landings from the artisan fishing fleet on Costa Rica’s Pacific coast between 1988 and 1997. The data come from an invoicing system administered by the Costa Rican Fisheries Institute (Instituto Costarricense de la Pesca y Acuacultura, INCOPESCA. Pacific coast shark fishing during the period under study represented approximately 20% of the total national fisheries volume. According to data from the invoicing system, the Northern Pacific region was the most productive, reporting 58% of the shark catch nationwide. Within this region, shark fishing in Papagayo Gulf represented 91% and 53% of the landings by fishery region and nationwide, respectively. The mid-sized and advanced (length of boat > 10 meters artisan fishing fleets reported 96% of the shark catches in the zone. The study of shark fisheries in the Papagayo Gulf zone is crucial for an understanding of fishery dynamics for this resource at the national level.

    The consumption of fruits and it relation with the health and socioeconomic condition of an adult Costa Rican population is described. The study included a cross sectional and descriptive analysis in men and women 18 years old or older. Ten-house blocks were selected by affinity in a community or neighborhood in Cartago. Data were collected in a survey using home direct structured interviews carried out in the afternoons or during the weekend in February, 2000. Eighty percent of the 161 people interviewed were women. Results showed that the higher consumption of fruits was described in women who were older that 60 years old and, who proceed from a medium-high economic stratum or have a high schooling condition (2.3 +/- 1.0, 2.50 +/- 1.3 y 2.0 +/- 1.3 portions, respectively). No statistical significant difference was found in any of the variables evaluated. Data also showed that, in contrast with what it was expected, people that considered their health condition as bad, suffered chronic diseases, practiced physical exercise, took vitamin supplement or smoke, showed a higher consumption of fruits that those who do not have those conditions. The difference, however, showed to be no significant and the consumption of fruit showed to be not adequate in both groups. In conclusion, the amount and frequency of fruit consumption were inadequate in the population studied. The necessity of developing nutritional education strategies to promote a gradual increment in the consumption of fruits to approach the recommendation of the National Alimentary Guidelines is recommended.

    Full Text Available Abstract Current complexities of English teaching in Costa Rica’s public secondary education are discussed. Using an autoethnographic research approach, critical incidents of an EFL teacher are examined in light of Complexity Theory. Findings suggest that classrooms are unpredictable sites of struggle where multiple rationalities coexist (and often conflict, which must be understood before random decisions are made. For applied linguistics, the study is relevant at three levels: it expands the bulk of literature on the subject, it calls for more attention to the complexities of EFL, and it opens an avenue for reflection and future research directions. Resumen Se analizan ciertos aspectos de las complejidades actuales sobre la enseñanza del inglés de secundaria en la educación pública de Costa Rica. Mediante la autoetnografía, se analizan incidentes críticos de un docente de inglés como lengua extranjera, a la luz de la teoría de la complejidad. Los hallazgos indican que el aula es un espacio de enfrentamientos entre las distintas racionalidades que coexisten, que deben comprenderse ante cualquier toma de decisiones. El estudio atiende tres aspectos: expande la bibliografía sobre el tema, resalta las complejidades de la enseñanza de lenguas extranjeras y abre espacios de reflexión y rutas para investigaciones futuras.

    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.

    Demand for long-term care services for older people is increasing rapidly in low- and middle-income countries. Countries need to establish national long-term care systems that are sustainable and equitable. The Governments of Costa Rica and Thailand have implemented broadly comparable interventions to deploy volunteers in long-term home care. Both countries trained older volunteers from local communities to make home visits to impoverished and vulnerable older people and to facilitate access to health services and other social services. Costa Rica and Thailand are upper-middle-income countries with strong traditions of community-based health services that they are now extending into long-term care for older people. Between 2003 and 2013 Thailand's programme trained over 51 000 volunteers, reaching almost 800 000 older people. Between 2010 and 2016 Costa Rica established 50 community care networks, serving around 10 000 people and involving over 5000 volunteers. Despite some evidence of benefits to the physical and mental health of older people and greater uptake of other services, a large burden of unmet care needs and signs of a growth of unregulated private services still exist. There is scope for low- and middle-income countries to develop large-scale networks of community-based long-term care volunteers. The capacity of volunteers to enhance the quality of life of clients is affected by the local availability of care services. Volunteer care networks should be complemented by other initiatives, including training about health in later life for volunteers, and investment in community long-term care services.

    Full Text Available Risk factors for the onset of cognitive impairment in Costa Rica are not well understood, despite a substantial elderly population stemming from a higher than average life expectancy for the western hemisphere. To investigate the risk factors that predict the onset of cognitive impairment in the rural elderly of Costa Rica, a modified version of the Mini Mental State Exam-designed for illiterate populations-was administered to 90 elderly inhabitants of San Carlos, Alajuela, Costa Rica between April and May of 2011. Subsequently, each participant took a structured interview assessing viability of risk factors and behaviors potentially contributing to a diagnosis of cognitive impairment. Results showed strong dependencies between age (p=0.0001, education level (p=0.0095, the ability to read (p=0.0001 and write (p=0.0153, frequency of reading (p=0.0011, use of puzzles and mind games (p<0.0001, vocation (p=0.0225, area of residence (p<0.0001, comorbid mental diseases (p=0.0005, history of stroke or brain trauma (p=0.0104, urinary or renal problems (p=0.0443, consistent cooking practices (p=0.0262 and number of living companions (p=0.0299 in susceptibility for developing cognitive impairment. The study concluded that high intellectual use, or lack thereof, during the lifetime of a person was a predictor for cognitive status later in life. In addition, comorbid mental disorders, including neurological trauma due to stroke, impeded normal cognitive function. Future research should examine incidence and risk factors of cognitive impairment in urban, more educated populations. Rev. Biol. Trop. 62 (3: 869-876. Epub 2014 September 01.

  9. The annual cycle and biological effects of the Costa Rica Dome

    2002-02-01

    The Costa Rica Dome is similar to other tropical thermocline domes in several respects: it is part of an east-west thermocline ridge associated with the equatorial circulation, surface currents flow cyclonically around it, and its seasonal evolution is affected by large-scale wind patterns. The Costa Rica Dome is unique because it is also forced by a coastal wind jet. Monthly climatological fields of thermocline depth and physical forcing variables (wind stress curl and surface current divergence) were analyzed to examine the structure and seasonal evolution of the dome. The annual cycle of the dome can be explained by wind forcing in four stages: (1) coastal shoaling of the thermocline off the Gulf of Papagayo during February-April, forced by Ekman pumping on the equatorward side of the Papagayo wind jet; (2) separation from the coast during May-June when the intertropical convergence zone (ITCZ) moves north to the countercurrent thermocline ridge, the wind jet stops, and the North Equatorial Countercurrent extends toward the coast on the equatorward flank of the ridge; (3) countercurrent thermocline ridging during July-November, when the dome expands to the west as the countercurrent thermocline ridge shoals beneath a band of cyclonic wind stress curl on the poleward side of the ITCZ; and (4) deepening during December-January when the ITCZ moves south and strong trade winds blow over the dome. Coastal eddies may be involved in the coastal shoaling observed during February-March. A seasonally predictable, strong, and shallow thermocline makes the Costa Rica Dome a distinct biological habitat where phytoplankton and zooplankton biomass are higher than in surrounding tropical waters. The physical structure and biological productivity of the dome affect the distribution and feeding of whales and dolphins, probably through forage availability.

    Ferlaviruses (FV, previously referred to as ophidian paramyxoviruses, OPMV), are enveloped viruses with a negative-strand RNA genome, affecting snakes in captivity worldwide. Infection is characterized by respiratory and nervous clinical signs and carries high mortality rates, but no specific treatment or vaccine is currently available. Costa Rica has 16 species of vipers, found in captivity in collections essential for antivenom production, reintroduction, and public education. FV circulation in these populations was previously unknown, and the risk of introducing the viruses into naïve collections or free-ranging populations exists if the virus's presence is confirmed. The objective of this study was to determine seroprevalence and FV shedding in 150 samples from captive vipers in nine collections across Costa Rica. A hemagglutination inhibition (HI) assay was performed to determine the antibody titer against two Ferlavirus strains, Bush viper virus (BV) and Neotropical virus (NT), and reverse-transcriptase polymerase chain reaction (RT-PCR) and sequencing to determine virus secretion in cloacal swabs. Ferlavirus strains were replicated in Vero cells, and chicken anti-FV polyclonal antibodies were produced and used as a positive control serum for the HI. Results demonstrate that seroprevalence of anti-FV antibodies in viper serum was 26.6% (n = 40) for the BV strain and 30% (n = 45) for the NT strain in the population tested. Furthermore, molecular characterization of FV group A was possible by sequencing the virus recovered from three cloacal swabs, demonstrating circulation of FV in one collection. This study demonstrates for the first time serological evidence of FV exposure and infection in vipers in captivity in Costa Rica, and suggests cross reactivity between antibodies against both strains. Appropriate biosafety measures could prevent the spread of FV between and within collections of reptiles in the country.

Además, se caracterizó a ese segmento poblacional a partir de diferentes variables: sexo, edad, estado civil y distribución geográfica. También se abordaron otros aspectos como fueron: alfabetismo, nivel de educación, ocupación, jefatura de hogar y vivienda. Entre los hallazgos más destacables se encuentra la permanencia, en los registros censales del siglo XX, de un concepto de discapacidad basado en la deficiencia, lo que definió los criterios de clasificación para esa población en esas fuentes. Asimismo se constató, por una parte, la asociación entre discapacidad e inequidad en esa centuria y, por la otra, la fragilidad de los vínculos de parentesco en ese grupo poblacional con respecto al conjunto de hogares de Costa Rica a fines de ese siglo. Las fuentes empleadas en esta investigación fueron los censos de población de Costa Rica del siglo XX. En el procedimiento con los datos, se llevó a cabo un análisis descriptivo de distribución de frecuencias.

    International market forces have played an increasingly important role in shaping land use dynamics through complex supply chains. In Costa Rica, the shift from a net loss to a net gain in forest cover was facilitated by forest plantations and the replacement of extensive cropland and pastures by export-oriented, high-yielding crops. However, agricultural intensification generated several feedbacks affecting forests. We analyzed the interactions between Costa Rica’s agricultural and forestry ...

    Serrano-Sandí, Juan; Bonilla-Murillo, Fabian; Sasa, Mahmood

    2013-09-01

    In Central America, palm swamps are known collectively as yolillales. These wetlands are usually dominated by the raffia palm Raphia taedigera, but also by the royal palm Manicaria saccifera and -in lower extensions- by the American oil palm Elaeis oleifera. The yolillales tend to be poor in woody species and are characteristic of regions with high rainfall and extensive hydroperiods, so they remain flooded most of the year. The dominance of large raffia palm leaves in the canopy, allow these environments to be distinguishable in aerial photographs, which consequently has helped to map them along most of their distribution. However, while maps depicting yolillales are available, the extent of their surface area, perimeter and connectivity remains poorly understood. This is particularly true for yolillales in Costa Rica and Nicaragua, countries that share a good proportion of palm dominated swaps in the Rio San Juan Basin. In addition, it is not known the actual area of these environments that is under any category of protection according to the conservation systems of both countries. As a first step to catalog yolillal wetlands in Costa Rica and Nicaragua, this paper evaluates cartographic maps to delineate yolillales in the region. A subsample of yolillales mapped in this study were visited and we geo-referenced them and evaluate the extent and condition of the swamp. A total of 110 883.2ha are classified as yolillales in Nicaragua, equivalent to 22% of wetland surface area recorded for that country (excluding the Cocibolca and Xolothn Lakes). In Costa Rica, 53 931.3ha are covered by these palm dominated swamps, which represent 16.24% of the total surface area covered by wetlands. About 47% of the area covered by yolillales in Nicaragua is under some category of protection, the largest extensions protected by Cerro Silva, Laguna Tale Sulumas and Indio Maiz Nature Reserves. In Costa Rica, 55.5% of the area covered by yolillal is located within protected areas

    Several expeditions in recent years to Isla del Coco have increased the total number of species of fishes known from the island. Several of these species have been described as new endemics (Bussing 1983, 1990, 1991a, 1991b, 1997). During the 1972 R/V Searcher Expedition to Costa Rica several trawl collections were made around Isla del Coco. At five localities in depths between 110 and 180m, 86 specimens of a new species of Peristedion were taken and are described herein. A key to the four species of Eastern Pacific Peristedion is included.

    Abstract The new species Rhopalosiphum chusqueae Pérez Hidalgo & Villalobos Muller, is described from apterous viviparous females caught on Chusquea tomentosa in Cerro de la Muerte (Costa Rica). The identity of the species is supported both by the morphological features and by a molecular phylogenetic analysis based on a fragment of the mitochondrial DNA containing the 5’ region of the cytochrome c oxidase 1 (COI) and on the nuclear gene coding for the Elongation factor-1 alpha (EF1α). The taxonomic position of the new species is discussed. An identification key to the Aphidinae species living on plants of Bambusoideae (Poaceae) is presented. PMID:22328859

    The dry ecosystems in the ignimbrite meseta of Guanacaste, northwest Costa Rica is mapped. Plant community distribution is intimately related to the type of relief, soils and humidity. In the upper parts of the meseta, characterised by soils which are stony, sandy, and acidic, herbacious vegetation such as savanna and edaphic steppe is dominant. By contrast, woodland is found on the deep and organically rich soils of the valley floors. Within the herbaceous formations dwarf varieties of Byrsonima crassifolia (nance), Curatella americana (raspa guacal) and Quercus oleoides (encino) are found because of the acid and infertile soils.

    Full Text Available Se midieron 31 ejemplares de tortuga africana de espolones Geochelone sulcata para la realización de un estudio biométrico. Se consideraron 26 medidas morfológicas para cada individuo. Las tortugas tenían una edad de entre 5 y 34 meses, y ninguna había alcanzado la madurez sexual. Todas ellas habían nacido en cautiverio en La Garita de Alajuela, Costa Rica, donde son una especie introducida. La longitud recta del espaldar fue de 83.1 mm, la anchura recta del espaldar de 68.3 mm y la altura máxima media de 46.2 mm. Todas las medidas estaban correlacionadas entre sí, salvo la longitud de la cola y la distancia cloacal. El mayor coeficiente de alometría positiva correspondió a la variable Peso. El mayor coeficiente de alometría negativa correspondió a la anchura a nivel de los escudos gulares. Todas las variables se agruparon en dos componentes principales, la longitud de la cola y la distancia cloacal en el Factor 2 y el resto en el Factor 1. La falta de correlación de las medidas de la cola así como su inclusión en un factor aparte al resto de la muestra podría responder a un proceso incipiente de diferenciación sexualGross morphometry of young Geochelone sulcata (Testudines: Testudinidae in Costa Rica.

    Pentastomids are parasites that infect respiratory cavities of vertebrates, they are pretty common but poorly known in wildlife veterinary. A Bothrops asper snake (Garman, 1884) was captured in the Caribbean region of Costa Rica and had its lung infested with pentastomids, identified as ca Porocephalus clavatus (Wyman, 1845). This represents the first record of Porocephalus (Humboldt, 1812) on B. asper as well as P. cf. clavatus in Costa Rica. Further studies are needed to clarify their taxonomic position, images and scanning electron microscopy photographs (SEM) of the specimens are given.

    A new species of terrestrial pitviper, Porthidium porrasi, is described from mesophytic forests of the Península de Osa and surrounding area of the Pacific versant of southwestern Costa Rica. It is most similar to P. nasutum and is characterized by a pattern of bands, persistence of the juvenile tail color in adults, and a high number of dorsal scales. Analysis of mtDNA sequences confirms its distinction from P. nasutum. The existence of this species reinforces the notion of elevated herpetofaunal endemism in southwestern Costa Rica.

    Recent studies in Central America indicate that mortality attributable to chronic kidney disease (CKD) is rising rapidly. We sought to determine the prevalence and regional variation of CKD and the relationship of biologic and socio-economic factors to CKD risk in the older-adult population of Costa Rica. We used data from the Costa Rican Longevity and Health Aging Study (CRELES). The cohort was comprised of 2657 adults born before 1946 in Costa Rica, chosen through a sampling algorithm to represent the national population of Costa Ricans >60 years of age. Participants answered questionnaire data and completed laboratory testing. The primary outcome of this study was CKD, defined as an estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m2 . The estimated prevalence of CKD for older Costa Ricans was 20% (95% CI 18.5-21.9%). In multivariable logistic regression, older age (adjusted odds ratio [aOR] 1.08 per year, 95% CI 1.07-1.10, P < 0.001) was independently associated with CKD. For every 200 m above sea level of residence, subjects' odds of CKD increased 26% (aOR 1.26 95% CI 1.15-1.38, P < 0.001). There was large regional variation in adjusted CKD prevalence, highest in Limon (40%, 95% CI 30-50%) and Guanacaste (36%, 95% CI 26-46%) provinces. Regional and altitude effects remained robust after adjustment for socio-economic status. We observed large regional and altitude-related variations in CKD prevalence in Costa Rica, not explained by the distribution of traditional CKD risk factors. More studies are needed to explore the potential association of geographic and environmental exposures with the risk of CKD. © 2015 John Wiley & Sons Ltd.

    Full Text Available Prácticamente todas las escuelas del pensamiento económico reconocen que las economías no se mueven de forma lineal sino que siguen un patrón cíclico recurrente que alterna periodos de altos con bajos niveles de actividad. El análisis de la naturaleza, causas y consecuencias de tales expansiones y contracciones es el principal objetivo de la Teoría de los Ciclos de Negocios (CN.A pesar que la comprensión de la naturaleza, causas y dinámica de un ciclo es vital tanto para los formuladores de política como para el sector privado, son pocos los intentos por brindar una interpretación económica de tales fluctuaciones en países pequeños y abiertos como Costa Rica. Así, queda aun una importante brecha teórica y empírica que explique las regularidades cíclicas presenten a estas naciones.El presente artículo es un intento en ese sentido. El trabajo busca evaluar si el patrón observado en la economía costarricense pertenece a un CN, y si así fuese, explorar en la causa y origen de los impulsos que dan lugar a esos movimientos. Con ello se amplía y complementa algunas investigaciones hechas anteriormente por autores como Azofeifa y otros (1995 y Gaba y otros (1993, de corte más estadístico.La principal conclusión del artículo es que, efectivamente, el patrón cíclico de Costa Rica puede ser considerado como un CN cuya causa se encuentra en las variaciones de la inversión. Los cambios experimentados en ella están alta, pero no exclusivamente, condicionados por el ciclo de los Estados Unidos, el cual canaliza sus fluctuaciones por medio de cambios en exportaciones y tasas de interés. Para tal efecto, el trabajo La investigación se apoya en un modelo kaleckiano/keynesiano que describe la secuencia impulso, causa y ciclo. Empíricamente, se utilizan herramientas econométricas varias tales como Modelos ARIMA y Vectores Autorregresivos para extraer el componente cíclico y probar la relación entre EEUU y Costa Rica.
