    1986-10-01

    Background notes by the U.S. States Department on the landlocked country of Bolivia, in the center of South America are presented. Bolivia has 6.25 million persons, about 1/3 each of Aymara indians, Quechua indians and mixed races. The growth rate is 2.6%, despite high death rates: infant mortality is 123/1000 and life expectancy is 49 years. There are fertile tropical lowland climate, hills and valleys, high plateaus and very high, dry cold mountain regions. Bolivia is the least developed, poorest nation in South America (per capita income is $536). There are remarkable cultural resources in archaeology, art, music, folklore and crafts, however. The country is plagued with military coups, social unrest, debt, poverty, and the disruption of international traffic in illegal drugs. One of the major resources, tin, has been lost as income due to collapse in tin prices in 1985. Other resources include natural gas, zinc, silver, tungsten, coffee, and undeveloped lithium, potassium and borax. Bolivia has had difficulties with border disputes with Chile, and since 1980, with many former friendly nations, including the U.S. due to a repressive military dictatorship. Recently, a more moderate government came into power, and relations and economic aid have resumed. PMID:12177934

  3. Bolivia Deforestation

    Science.gov (United States)

    2002-01-01

    Once a vast carpet of healthy vegetation and virgin forest, the Amazon rain forest is changing rapidly. This image of Bolivia shows dramatic deforestation in the Amazon Basin. Loggers have cut long paths into the forest, while ranchers have cleared large blocks for their herds. Fanning out from these clear-cut areas are settlements built in radial arrangements of fields and farms. Healthy vegetation appears bright red in this image. This scene was acquired by Landsat 7's Enhanced Thematic Mapper plus (ETM+) sensor on January 8, 2000. This is a false-color composite image made using infrared, red, and green wavelengths. The image has also been sharpened using the sensor's panchromatic band. Image provided by the USGS EROS Data Center Satellite Systems Branch

    Full Text Available This article analyzes the main problems that the new Political Constitution of Bolivia is facing before being implemented, once it was approved on February 2009. In addition, it also studies how the constitutional provisions were negotiated in order to make the constitutional referendum viable. What were the political conflicts in the critical juncture 2008-2009, and what kind of reflection should be considered as to how the new emerging regional and local governments—together with its decentralized structures—are able to renew democracy in Bolivia within the framework of the Plurinational State? The multiple challenges ahead are highly difficult to confront from democratic theory perspectives.

    2002-01-01

    This image from Landsat7, acquired on August 1, 2000, shows the new agricultural settlements east of Santa Cruz de la Sierra, Bolivia in an area of tropical dry forest. Since the mid-1980s, this region has been rapidly deforested as a result of the resettlement of people from the Altiplano (the Andean high plains) and a large agricultural development effort, called the Tierras Baja project. The pie or radial patterned fields (left) are part of the San Javier resettlement scheme. At the center of each unit is a small community including a church, bar/cafe, school, and soccer field-the essentials of life in rural Bolivia. The rectilinear, light-colored areas (right) are fields of soybeans cultivated for export that are mostly funded by foreign loans. The dark strips running through these fields are wind breaks. These are advantageous because the soils in this area are fine and prone to wind erosion.

  7. Bolivia: A Gasified Democracy

    Directory of Open Access Journals (Sweden)

    2004-04-01

    Full Text Available In October 2003 a wave of popular protest  brought down the Sánchez de Lozada government  in Bolivia. The intention to export natural gas to  the United States and Mexico triggered the protests, but actually stood for widespread discontent  with the Sánchez de Lozada government, the  preceding governments and the economic policies  pursued since 1985. The events belie the opinion  of various students of the Latin American democratic transitions who held that Bolivian democracy  was on its way towards consolidation and suggest that the recent inquiries into the quality of Latin  American democracies may point a way ahead in  rethinking democracy in the region. Taking such  assessments as a reference, this article reviews the  ‘gas war’ and looks at the Bolivian political regime as it has functioned over the past decades. It  will be argued that the ‘pacted democracy’, that  until now sustained institutionality, and the economic model adopted in 1985 have excluded an  important part of the population, both in political terms and where poverty alleviation and equity is  concerned. Increasing popular protest has been  met with increasing repression, which gradually  turned Bolivia into a ‘democradura’, or a ‘gasified  democracy’ that relies on teargas and bullets to  uphold itself. At present the country finds itself at  a crossroads. It either may reinvent democracy or  become an institutionalized ‘democradura’. Resumen: Bolivia: una democracia gasificadaEn octubre de 2003 una ola de protesta popular  llevó a la caída del gobierno de Sánchez de Lozada en Bolivia.

    The Bolivian LANDSAT Program is an integrated, multidisciplinary project designed to provide thematic analysis of LANDSAT, Skylab, and other remotely sensed data for natural resource management and development in Bolivia, is discussed. Among the first requirements in the program is the development of a legend, and appropriate methodologies, for the analysis and classification of present land use based on landscape cover. The land use legend for Bolivia consists of approximately 80 categories in a hierarchical organization which may be collapsed for generalization, or expanded for greater detail. The categories, and their definitions, provide for both a graphic and textual description of the complex and diverse landscapes found in Bolivia, and are designed for analysis from LANDSAT and other remotely sensed data at scales of 1:1,000,000 and 1:250,000. Procedures and example products developed are described and illustrated, for the systematic analysis and mapping of present land use for all of Bolivia.

    Smith, P.

    1997-12-01

    The author summarizes changes which have occurred in Bolivia in the past year which have had an impact on renewable energy source development. Political changes have included the privatization of power generation and power distribution, and resulted in a new role for state level government and participation by the individual. A National Rural Electrification Plan was adopted in 1996, which stresses the use of GIS analysis and emphasizes factors such as off grid, economic index, population density, maintenance risk, and local organizational structure. The USAID program has chosen to stress economic development, environmental programs, and health over village power programs. The national renewables program has adopted a new development direction, with state projects, geothermal projects, and private sector involvement stressed.

    2008-01-01

    This report looks at Bolivia's main economic indicators over the past year (mid-2006 to mid-2007), noting improvements in growth, fiscal balances, balance of payments, and international reserves. These improvements were largely due to government policies and choices, such as increased hydrocarbons royalties and control over the hydrocarbons sector, and have allowed the government to embark on a number of programs targeting the poor and landless. The report also notes that Bolivia faces many challenges: expansion of land reform, more rapid growth and poverty reduction, the reduction of regional and demographic disparities, and an accelerated diversification of the economy away from hydrocarbons and minerals.

    Started in 2011, the GeoBolivia project (www.geo.gob.bo)aims at building the Spatial Data Infrastructure of the Plurinational State of Bolivia (IDE-EPB by its Spanish initials), as an effort of the Vice Presidency of the State to give an open access to the public geographic information of Bolivia. The first phase of the project has already been completed. It consisted in implementing an infrastructure and a geoportal for accessing the geographic information through WMS, WFS, WCS and CSW services. The project is currently in its second phase dedicated to decentralizing the structure of IDE-EPB and promoting its use throughout the Bolivian State. The whole platform uses free software and open standards. As a complement, an on-line training module was developed to undertake the transfer of the knowledge the project generated. The main software components used in the SDI are: gvSIG, QGis, uDig as GIS desktop clients; PostGreSQL and PostGIS as geographic database management system; geOrchestra as a framework containing the GeoServer map server, the GeoNetwork catalog server and the OpenLayers and Mapfish GIS webclient; MapServer as a map server for generating OpenStreetMap tiles; Debian as operating system; Apache and Tomcat as web servers.

  15. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Bolivia

    International Nuclear Information System (INIS)

    Bolivia has an area of 1,098,580 square kilometers. Its capital is La Paz. The western part of the country is dominated by two ranges of the Andes Mountains, the Cordillera Occidental on the vest flank of the high plateau (Altiplano) and the Cordillera Real (or Oriental) on the east flank. The northern Andes average 5,486 meters in elevation; the southern Andes are not as lofty. The Altiplano is 3,658 to A,267 meters high and 129 km. in average width; it is the largest basin of inland drainage in South America and contains the renowned Lake Titicaca on the Peruvian-Bolivian border. The eastern tropical lowlands or pampas (Oriente) comprise about two-thirds of the country, with rain forest in the northern portion. An intermediate zone of valleys and basins lies between the eastern Andes and Oriente. Bolivia differs from other Andean countries, like Chile, Peru and Ecuador, in having large areas of Preeambrian schists, gneisses, migmatites and granites. These crop out in the eastern part of the country. Parts of these rocks contain banded iron formations (i.e., in the Muttin region) and are probably early Precambrian in age. Little systematic exploration for uranium was undertaken in Bolivia until the late 1960's. In 1967, 1968 and 1969 technical assistance was requested from, and provided by, the IAEA. This work led to evaluation of radioactive anomalies in veins of northeast Bolivia and in sandstones in the extreme southern part of the country. Although no uranium reserves are now credited to Bolivia, the geologic possibilities for several kinds of uranium deposits coupled with the relatively limited work done to date suggest that uranium orebodies will be discovered. It is estimated that the potential resources of Bolivia are in the range of 10,000 to 100,000 tonnes uranium

    Background The aim of this study was to document the types of diseases treated by the use of medicinal plants, their main applications and also to have a report of the major diseases treated at the Hospital of San Pablo de Huacareta (Chuquisaca Bolivia). Methods We conducted semi-structured interviews on the use medicinal plants with 10 local informants, and categorized the kinds of diseases treated by traditional medicine. We obtained reports of cases treated at the Hospital of Huacareta in order to compare the use frequency of traditional medicine and allopathic medicine for the treatment of recurrent diseases in the area. Results Our survey identified 258 traditional medicine uses, spanning a total of 13 diseases categories and including 91 native and exotic plant species and one unidentified sample plant type. Gastrointestinal disorders (55%) were most frequently treated with medicinal plants, followed by afflictions of the musculoskeletal system (25%) and dermatological disorders (24%). Hospital information indicates that the most common diseases are acute respiratory infections (47%) and acute diarrheal diseases (37%). The herbal remedies were mostly used in the form of teas and decoctions. The informants used mainly native plant species, although exotic species has been introduced to the pharmacopoeia. Conclusions The treatment of gastrointestinal disorders is the primary objective of the medical ethnobotany of the inhabitants of Huacareta, while respiratory system diseases are mostly treated in the hospital. Looking at the data from the Hospital records we can infer that gastrointestinal disorders are among the most common diseases in the study area. For most respondents, traditional medicine is a reliable choice for the care of their illnesses. However, the preference of the population for either traditional medicine or allopathic medicine needs to be clarified in future comparative studies to obtain more convincing results. The results presented can be

  19. The Decolonization of Bolivia's Antinarcotics Policy?

    Directory of Open Access Journals (Sweden)

    2016-03-01

    Este artículo sostiene que, en el siglo XX, se desarrolló una forma peculiar de colonización en la política antinarcótica de Bolivia, compuesta por rasgos parecidos a los del colonialismo externo e interno. Por una parte, las instituciones internacionales y los Estados Unidos lograron imponer en el país un sistema de control y prohibición del cultivo y consumo de la hoja de coca. Por otra parte,  la élite gobernante apoyada por los EE.UU. impuso su poder y dominio sobre los cocaleros al introducir esta prohibición  y promover la erradicación forzosa de la coca con el auspicio de EE.UU., poniendo en severo peligro los derechos de los  cocaleros. A diferencia de anteriores gobiernos que aceptaron pasivamente las decisiones tomadas en foros internacionales acerca de la clasificación de la hoja de coca como droga ilegal y siguieron con rigor las instrucciones de los EE.UU. acerca de la erradicación de la coca, el gobierno de Evo Morales está actuando para cambiar la situación  en un doble esfuerzo internacional y nacional. Analizando las políticas de este gobierno entre 2006-2014, este artículo sostiene que en el manejo de la política antinarcótica está siguiendo un proceso particular de descolonización para defender los usos tradicionales de la hoja de coca y proteger los derechos sociales, económicos y culturales de las poblaciones andinas involucradas en su producción y/o consumo, y promover el desarrollo económico de las áreas donde se cultiva.

    Full Text Available Introduction: Neural Tube Defects (NTD are the second congenital malformation, second only to cardiac malformations. Myelomeningocele (MMCL is the most frequent NTD and the more complex. In Bolivia, like in many countries in South America, the low socio economical level of the population increases its incidences and complicates its management. Materials and Methods: Retrospective study of 70 cases of MMC at Hospital Universitario Japonés (HUJ, Santa Cruz de la Sierra, between 2008-2011. Sixty had surgery. Results: Prenatal care in 27 women (38.6%, positive diagnosis for spinal disraphism in 2 (7.4%. The child arrived after 24 hours of birth (65.5%. Lumbosacral lesion (64.3%. Of those 67.2% were open, with 32.9% evidencing partial motor lesion in contrast with 47.1% who were paraplegic bellow the level of the lesion. Three children were not operated because they had complex and severe malformations associated to the MMCL. The most common surgical complications were; wound dehiscence or infection (16.6%, CSF fistula (10% CNS infection (11.7%. Mortality and specifically postoperative mortality were 7.1% y 3.3%, respectively. Hydrocephalus wass evident in 80% of the patients who were operated, they received a VP shunt medium pressure. Nine patients who had long term follow up presented with tethered cord. Conclusions: A characteristic, delayed referral. No gender predominance. Majority of cases were lumbar or lumbar sacral. Mortality similar to what is reported in the literature. Few patients came for follow up. MMCL is a pathology that requires concentrated attention by the national authorities. A multi center and multi national study will improve our management of these patients.

    1999-10-01

    Bolivia, with its large oil and natural gas potential, is becoming an increasingly important link in South American energy trade. With new fields and pipeline construction, the nation is becoming the natural gas hub for the Southern Cone. In 1998, Bolivia experienced 4,7% GDP growth, the fastest in South America, and Bolivia's best performance since 1988. In addition, Bolivia brought its inflation rate to a 2-decade low of 4,4 %. In addition to tight global capital markets, investments also is expected to decrease due to the completion of the Bolivia to Brazil gas pipeline. This extremely capital-intensive project accounted for a significant portion of Bolivia's investment for 1998 and 1999. Bolivia has made significant economic improvements over the past few years by adopting a series of free market policies. The mayor improvements in economic growth have been made possible primarily through the government's unique capitalization program of key national industries. In addition to the Capitalization Program, Bolivia's economic growth is a result of its involvement in several free trade associations. Bolivia, as well as Chile, is an associate partner of the Mercosur, whose members include Argentina, Brazil, Paraguay and Uruguay. Bolivia is also member of the Andean Pact, which comprises Peru, Colombia, Ecuador and Venezuela. Bolivia's unique involvement in both of these trade groups is allowing it to become an important cornerstone in the integration of the South American continent. Specifically, Bolivia is increasingly becoming an important transport hub within the continent. Energy is one of the main products Bolivia is attempting to transport. According to the government, nearly $5 billion of investment is needed by 2005 so Bolivia can succesfully develop its oil and gas reserves, build pipelines, and construct power plants if it wishes to emerge as the regional hub.

    Introducción: Las malformaciones del tubo neural (MTN) representan la segunda causa más frecuente de anomalías congénitas, luego de las cardiopatías. En este grupo se destaca el mielomeningocele (MMC) por su mayor incidencia, y por ser la más incapacitante y la más compleja entre todas las demás malformaciones del sistema nervioso c`entral (SNC). En Bolivia, como en muchos países de Sudamérica, los bajos niveles socio-culturales y la debilidad en el sistema sanitario, hacen que su incidencia y su morbilidad, sean mayores que en las naciones más desarrolladas. Material y Métodos: Se realizó un estudio retrospectivo y descriptivo de 70 casos de MMC, atendidos por un equipo multidisciplinario en el Hospital Universitario Japonés (HUJ) de Santa Cruz de la Sierra, entre 2008-2011. De ellos, 60 fueron intervenidos quirúrgicamente. Resultados: Se realizaron controles prenatales sólo en 27 mujeres (38.6%), diagnosticándose una disrafia espinal en apenas dos casos (7.4%). La edad de ingreso del MMC en su mayoría fue después de las 24 horas (65.6%), predominando su localización en la región lumbosacra (64.3%). De ellos, 67.2% eran abiertos, presentando un 32.9% un daño neurológico motor parcial mientras que 47.1% tenían paraplejia por debajo de la lesión. De los 70 casos, tres (4.3%) no fueron intervenidos, por presentar defectos congénitos severos o estado general grave. Las principales complicaciones posoperatorias inmediatas fueron: dehiscencia de sutura y/o infección de la herida (16.6%), fístula de líquido cefalorraquídeo (LCR) (10%) e infección del SNC (11.7%). La mortalidad general y postoperatoria fue de 7.1% y 3.3%, respectivamente. Al mes de vida presentaban hidrocefalia un 80% de los pacientes operados, colocándose una derivación ventriculoperitoneal (DVP) de presión media.

    This study presents monthly and annual climate maps for relevant hydroclimatic variables in Bolivia. We used the most complete network of precipitation and temperature stations available in Bolivia, which passed a careful quality control and temporal homogenization procedure. Monthly average maps at the spatial resolution of 1 km were modeled by means of a regression-based approach using topographic and geographic variables as predictors. The monthly average maximum and minimum temperatures, precipitation and potential exoatmospheric solar radiation under clear sky conditions are used to estimate the monthly average atmospheric evaporative demand by means of the Hargreaves model. Finally, the average water balance is estimated on a monthly and annual scale for each 1 km cell by means of the difference between precipitation and atmospheric evaporative demand. The digital layers used to create the maps are available in the digital repository of the Spanish National Research Council.

  2. The Nation State v. Indianist Revitalization Dialectic in Bolivia

    Directory of Open Access Journals (Sweden)

    Full Text Available Since early in 2006, the republic of Bolivia has been ruled by the first indigenous president in that country’s history: the Aymara Evo Morales, union leader and first name in the ballot of the so-called “Movement for Socialism” (MAS. His political rise, electoral victory and government program have drawn considerable attention from international mass media and been the subject of valuable political and sociological analyses. From the perspective of comparative anthropology, the process can be understood as an instance, in the Andean cultural context, of what Anthony Wallace called a “revitalization movement,” triggered by the convergence, at a juncture of crisis begun in 1997, of a number of historical conditions of variable duration in Bolivia as a national project.

    Desde comienzos de 2006, la república de Bolivia cuenta con el primer presidente indígena de su historia: el aymara Evo Morales, dirigente sindical y cabeza de lista del llamado “Movimiento al Socialismo” (MAS. Su ascensión política, victoria electoral y programa de gobierno han llamado mucho la atención de los medios informativos internacionales y han sido objeto de valiosos análisis políticos y sociológicos. Desde la perspectiva de una antropología comparada, el proceso se ajusta bien, en el contexto cultural andino, a lo que Anthony Wallace llamara un “movimiento de revitalización”, desencadenado por la convergencia, en un periodo de crisis iniciado en 1997, de varias condiciones estructurales de duración histórica variable en Bolivia como proyecto nacional.

    2007-11-01

    Land-cover change in eastern lowland Bolivia was documented using Landsat images from five epochs for all landscapes situated below the montane tree line at approximately 3000 m, including humid forest, inundated forest, seasonally dry forest, and cloud forest, as well as scrublands and grasslands. Deforestation in eastern Bolivia in 2004 covered 45,411 km2, representing approximately 9% of the original forest cover, with an additional conversion of 9042 km2 of scrub and savanna habitats representing 17% of total historical land-cover change. Annual rates of land-cover change increased from approximately 400 km2 y(-1) in the 1960s to approximately 2900 km2 y(-1) in the last epoch spanning 2001 to 2004. This study provides Bolivia with a spatially explicit information resource to monitor future land-cover change, a prerequisite for proposed mechanisms to compensate countries for reducing carbon emissions as a result of deforestation. A comparison of the most recent epoch with previous periods shows that policies enacted in the late 1990s to promote forest conservation had no observable impact on reducing deforestation and that deforestation actually increased in some protected areas. The rate of land-cover change continues to increase linearly nationwide, but is growing faster in the Santa Cruz department because of the expansion of mechanized agriculture and cattle farms.

    2016-02-01

    Bolivia is currently undergoing a series of healthcare reforms centred around the Unified Family, Community and Intercultural Health System (SAFCI), established in 2008 and Law 475 for Provision of Comprehensive Health Services enacted in 2014 as a first step towards universal health coverage. The SAFCI model aims to establish an intercultural, intersectoral and integrated primary health care (PHC) system, but there has not been a comprehensive analysis of effective strategies towards such an end. In this systematic review, we analyse research into developing PHC in Bolivia utilizing MEDLINE, the Virtual Health Library and grey literature from Pan American Health Organization/World Health Organization's internal database. We find that although progress has been made towards implementation of a healthcare system incorporating principles of PHC, further refining the system and targeting improvements effectively will require increased research and evaluation. Particularly in the 7 years since establishment of SAFCI, there has been a dearth of PHC research that makes evaluation of such key national policies impossible.

    Bolivia is currently undergoing a series of healthcare reforms centred around the Unified Family, Community and Intercultural Health System (SAFCI), established in 2008 and Law 475 for Provision of Comprehensive Health Services enacted in 2014 as a first step towards universal health coverage. The SAFCI model aims to establish an intercultural, intersectoral and integrated primary health care (PHC) system, but there has not been a comprehensive analysis of effective strategies towards such an end. In this systematic review, we analyse research into developing PHC in Bolivia utilizing MEDLINE, the Virtual Health Library and grey literature from Pan American Health Organization/World Health Organization's internal database. We find that although progress has been made towards implementation of a healthcare system incorporating principles of PHC, further refining the system and targeting improvements effectively will require increased research and evaluation. Particularly in the 7 years since establishment of SAFCI, there has been a dearth of PHC research that makes evaluation of such key national policies impossible. The quantity and quality of PHC research must be improved, especially quasi-experimental studies with adequate control groups. The infrastructure for such studies must be strengthened through improved financing mechanisms, expanded institutional capacity and setting national research priorities. Important for future progress are improved tracking of health indicators, which in Bolivia are often out-of-date or incomplete, and prioritization of focused national research priorities on relevant policy issues. This study aims to serve as an aid towards PHC development efforts at the national level, as well as provide lessons for countries globally attempting to build effective health systems accommodating of a multi-national population in the midst of development.

    The system of radiation in Bolivia has the radiation Protection and Safety Law with its own regulations for the control of ionizing radiation sources. The Competent National Authority is The Bolivian Institute of Science and Nuclear Technology (IBTEN). The control of ionizing radiation sources is based on several licenses and authorizations. Each one of these elements offers courses, personnel dosimetry, emergency response systems, calibration and others, etc. All the elements of control need to be followed by all the personnel involved for the efficient functioning of their jobs.

  14. Electrical conductivity of intermediate magmas from Uturuncu Volcano (Bolivia)

    Laumonier, Mickael; Gaillard, Fabrice; Sifre, David

    2015-04-01

    Magmas erupted at Uturuncu volcano (South Bolivia) comes from the Altiplano-Puna Magma Body (APMB, Chile-Bolivia), a crustal massive body of 80 km long by 10 km thick located at ~ 35 km depth named. Recent magneto telluric surveys reveal a resistivity lower than 1 ohm.m due to the presence of melt which could result in the reactivation of the volcano. In order to better constrain the resistivity profiles and thus the conditions of magma storage of the APMB, we have performed in situ electrical measurements on natural dacites and andesites from Uturuncu with a 4-wire set up in a piston cylinder and internally heated pressure vessel. The range of temperature (500 to 1300°C), pressure (0.3 to 2 Gpa), and the various water contents covers the respective ranges occurring at natural conditions. The results show that the conductivity increases with the temperature and the water content but slightly decreases with the pressure. Then a model was built from these results so as to help in (i) interpreting the electrical signature of natural magmas, (ii) constraining their conditions (chemical composition, temperature, pressure, water content, melt fraction) from the source to the storage location and (iii) providing information on the interior structure of a volcano and its reservoir.

    Full Text Available Chagas disease is a major public health problem in Bolivia. In the city of Cochabamba, 58% of the population lives in peripheral urban districts ("popular zones" where the infection prevalence is extremely high. From 1995 to 1999, we studied the demographics of Chagas infections in children from five to 13 years old (n = 2218 from the South zone (SZ and North zone (NZ districts, which differ in social, environmental, and agricultural conditions. Information gathered from these districts demonstrates qualitative and quantitative evidence for the active transmission of Trypanosoma cruzi in urban Cochabamba. Seropositivity was high in both zones (25% in SZ and 19% in NZ. We observed a high risk of infection in children from five to nine years old in SZ, but in NZ, a higher risk occurred in children aged 10-13, with odds ratio for infection three times higher in NZ than in SZ. This difference was not due to triatomine density, since more than 1,000 Triatoma infestans were captured in both zones, but was possibly secondary to the vector infection rate (79% in SZ and 37% in NZ. Electrocardiogram abnormalities were found to be prevalent in children and pre-adolescents (SZ = 40%, NZ = 17%, indicating that under continuous exposure to infection and re-infection, a severe form of the disease may develop early in life. This work demonstrates that T. cruzi infection should also be considered an urban health problem and is not restricted to the rural areas and small villages of Bolivia.

    Directory of Open Access Journals (Sweden)

    Pinto Aguirre, Guido

    2007-01-01

    Full Text Available The objective of the present study is to examine the effects of several reproductive and demographic factors on child survival in Bolivia, one of the most impoverished nations in all of Latin America. We model the joint effects of maternal age, parity, pace of childbearing, duration of breastfeeding, and use of modern contraception on child mortality. Data for this research come from “Demographic and Health Survey” (DHS carried out during 1998. The results obtained in this paper support the evidence found in other studies: breastfeeding and the pace of childbearing are the most important reproductive patterns affecting child mortality risks, and their strong, consistent effects tend to persist even after the introduction of various socioeconomic variables as controls: short preceding birth intervals and short durations of breastfeeding increase the risk of death during the first two years of life.

  20. ¿Qué ocurrió realmente en Bolivia?

    Mario Torrico

    2006-07-01

    Full Text Available This article seeks to dispute the explanations which assume that the process Bolivia is going through is similar to the processes other Latin–American countries are experiencing. These perspectives suggest the triumph of Evo Morales in the presidential elections of December 2005 was produced by the failure of the neoliberal policies carried out in this region during the period following the debt crisis of the eighties. Showing data that reveal that the bolivian economic performance in the neoliberal period was better compared to the performance of Argentina, Brazil and Mexico, this article offers an alternative explanation, which not denying the poverty of the bolivian majorities, asserts that the breakdown of the political system and the parties that alternated in power for twenty years is the main factor explaining the rise of the first indigenous president.

  1. Bolivia: New Presidential Electoral System and Political Parties Coordination

    Directory of Open Access Journals (Sweden)

    Mario Torrico

    2015-01-01

    Full Text Available This article analyzes the incentives generated by presidential electoral systems in Bolivia. The system that was in place until 2005 led to the formation of coalition governments that aimed at giving the Executive the majority in Congress. However, these coalitions gradually lost the electorate confidence, and citizens sought alternative political options to major parties from the early nineties on, giving rise to a social dissatisfaction with democracy. This, in turn, led to the resignation of Sánchez de Lozada and, later, to the triumph of Evo Morales. The new electoral system for electing the president, included in the 2009 Constitution, increases the likelihood that the elected government does not have a majority in Congress. Similar situations in the past led to political crisis and anticipation of elections. In a more favorable context characterized by greater satisfaction with democracy and their parties, the challenge is to take decisions inclusively, something unprecedented in Bolivian politics.

  4. Fiscal policy and economic growth: a simulation analysis for Bolivia

    Directory of Open Access Journals (Sweden)

    Carlos Gustavo Machicado

    2012-12-01

    Full Text Available This paper develops a dynamic stochastic general equilibrium (DSGE model to analyze the growth effects of fiscal policy in Bolivia. It is a multi-sector model with five representative sectors for the Bolivian economy: Non-tradables, importables, hydrocarbons, mining and agriculture. Public capital is included as a production factor in each of these sectors. The model is calibrated and a number of interesting scenarios are simulated by modifying each of the available fiscal policy instruments. In particular, we analyze the sustainability of Bolivian social policy based on government transfers to households along with the short- and long-run implications of fiscal policy for growth and welfare. We find that fiscal policy alone is unable to generate high rates of growth: it must be accompanied by an efficient provision of public capital and productivity boosts in the economic sectors.

Different actors with different interests worked together against the system, which became their “common antagonist”.  On the one hand, after years of autonomous organization, these social movements won social recognition and increased their power. On the other, political parties and trade unions lost legitimacy.  In December 2005, a faction of the Bolivian social movements won the general elections, and Evo Morales (the cocalero movement´s leader became the first Aymara president in Bolivian history.

    Full Text Available Voluntary Debt Reduction Operations. Bolivia, México, and Beyond This paper studies two recent voluntary operations of debt reduction: Bolivia's buy-back and Mexico's exchange of loans for bonds. This argued that the buy-back had a cost for Bolivia and, hence, it required a political decision when comparing this option to other alternative use of its scarce foreign exchange resources. In the case of Mexico, it is shown that the operation, which can be seen as an indirect buy-back, gave this country a rate of return on the use of its reserves, between 18% and 24%. The effects of both transactions on the debtor are examined, as well as on participating and non-participating creditor banks.

    Anisotropy in the upper mantle is often associated with mantle flow direction through the lattice preferred orientation of anisotropic minerals such as olivine in the upper mantle material. The flow of the mantle around subduction zones can be particularly complex, and thus difficult to explain. Because of its relationship to anisotropy, analysis of shear wave splitting measurements can help to answer questions regarding the upper mantle flow that surrounds subducting slabs. Here we present SK(K)S shear wave splitting measurements from a temporary broadband network (PLUTONS) of 33 stations deployed from April 2009 to October 2012 on the Altiplano plateau around Uturuncu volcano in Bolivia. The stations are spaced 10-20 km apart, providing a high spatial resolution of the region of the mantle directly below Uturuncu volcano. Despite the lack of numerous splitting results to analyze, preliminary measurements indicate a relatively consistent pattern of fast-polarization directions in a NW-SE orientation of about N80ºW. We think that it is likely that these observations come from anisotropy in the mantle wedge above the subducting Nazca plate indicating a direction of flow in the mantle wedge that is sub-parallel to the subduction direction of the Nazca plate. Although W-E flow beneath the subducting Nazca plate cannot be completely ruled out, these results appear to be consistent with the simple model of two-dimensional corner flow in the mantle wedge and slab-entrained mantle flow beneath the slab.

    Full Text Available Heavy domestic and peridomestic infestations of Triatoma infestans were controlled in two villages in southern Bolivia by the application of deltamethrin SC25 (2.5% suspension concentrate at a target dose of 25 mg a.i./m². Actual applied dose was monitored by HPLC analysis of filter papers placed at various heights on the house walls, and was shown to range from 0 to 59.6 about a mean of 28.5 mg a.i./m². Wall bioassays showed high mortality of T. infestans during the first month after the application of deltamethrin. Mortality declined to zero as summer temperatures increased, but reappeared with the onset of the following winter. In contrast, knockdown was apparent throughout the trial, showing no discernible temperature dependence. House infestation rates, measured by manual sampling and use of paper sheets to collect bug faeces, declined from 79% at the beginning of the trial to zero at the 6 month evaluation. All but one of the houses were still free of T. infestans at the final evaluation 12 months after spraying, although a small number of bugs were found at this time in 5 of 355 peridomestic dependencies. Comparative cost studies endorse the recommendation of large-scale application of deltamethrin, or pyrethroid of similar cost-effectiveness, as a means to eliminate domestic T. infestans populations in order to interrupt transmission of Chagas disease

    Uruguay and Bolivia are two countries that show heterogenicity of the Latin American region, including the national income, the expenditure on health and the services for renal care. In Bolivia, there is manpower shortage for renal care with only 5 nephrologists per million people (pmp) and the prevalence of patients on dialysis is only 200 pmp. This is much lower than the mean prevalence rate of renal replacement therapy for Latin America as a whole. Uruguay on the other hand has more dedicated renal resources with 50 nephrologists pmp, and renal replacement therapy is provided to ~ 1,000 dialysis patients pmp. In November 2012, a collaborative project financed by the Uruguayan International Cooperation Agency was signed by both the Uruguay and Bolivia Ministries of Health, and the goal was to develop a comprehensive program for the prevention and management of all stages of chronic kidney disease (CKD) in Bolivia. The specific objectives were to: a) promote renal healthcare in the primary healthcare setting, b) identify kidney disease in populations at risk, and c) optimize patient care at all stages of CKD, including dialysis and transplantation supported with a national ESRD registry in Bolivia. As a first step, delegates from the Bolivian Health Ministry, visited Uruguay in April 2014, primarily to strengthen the development of tools required for developing and maintaining a national registry. In addition, during this visit, a meeting with the president of the Latin American Society of Nephrology and Hypertension (SLANH) culminated in designing a training program for peritoneal dialysis. This highly cooperative relationship is advancing the prevention and care of CKD in Bolivia and may serve as a model for international approaches to advance system level CKD care in countries with limited healthcare resources.

This study examines the impact of unintended--mistimed or unwanted--pregnancy on breastfeeding duration. We use data from the 1990 Paraguay and 1994 Bolivia Demographic and Health Surveys and restrict our analysis to last-born, surviving children younger than 36 months from singleton births. To assess the association, unintended and intended pregnancies are compared by calculating incidence rates and adjusted hazard ratios (aHR) using survival analysis. Most children (approximately 95 percent) were breastfed initially, but the median duration of breastfeeding in Bolivia was five months longer than that in Paraguay (19 versus 14 months). A greater proportion of pregnancies were described as intended in Paraguay than in Bolivia (74 percent versus 45 percent). In adjusted analyses, unwanted and mistimed pregnancies were associated with slightly longer duration of breastfeeding (aHR = 0.9) than were intended pregnancies, but the association was not statistically significant. In this study, therefore, pregnancy intention was not an important factor in duration of breastfeeding in Bolivia or Paraguay.

    Paleoelevation histories from the central Andes in Bolivia have suggested that the geodynamic evolution of the region has been punctuated by periods of large-scale lithospheric removal that drive rapid increases in elevation at the surface. Here, we evaluate viable times and locations of material loss using a map-view reconstruction of the Bolivian orocline displacement field to forward-model predicted crustal thicknesses. Two volumetric models are presented that test assumed pre-deformation crustal thicknesses of 35 km and 40 km. Both models predict that modern crustal thicknesses were achieved first in the northern Eastern Cordillera (EC) by 30-20 Ma but remained below modern in the southern EC until ≤10 Ma. The Altiplano is predicted to have achieved modern crustal thickness after 10 Ma but only with a pre-deformation thickness of 50 km, including 10 km of sediment. At the final stage, the models predict 8-25% regional excess crustal volume compared to modern thickness, largely concentrated in the northern EC. The excess predicted volume from 20 to 0 Ma can be accounted for by: 1) crustal flow to the WC and/or Peru, 2) localized removal of the lower crust, or 3) a combination of the two. Only models with initial crustal thicknesses >35 km predict excess volumes sufficient to account for potential crustal thickness deficits in Peru and allow for lower crustal loss. However, both initial thickness models predict that modern crustal thicknesses were achieved over the same time periods that paleoelevation histories indicate the development of modern elevations. Localized removal of lower crust is only necessary in the northern EC where crustal thickness exceeds modern by 20 Ma, prior to paleoelevation estimates of modern elevations by 15 Ma. In the Altiplano, crustal thicknesses match modern values at 10 Ma and can only exceed modern values by 5 Ma, post-dating when modern elevations were thought to have been established. Collectively, these models predict that

    Full Text Available The regimes of Hugo Chávez, Evo Morales, and Rafael Correa undermine contestation while simultaneously increasing the material inclusion of the poor and the excluded. These regimes that are usually lumped together show distinct patterns in fostering participation. Whereas in Ecuador participation is reduced to voting in elections, participatory institutions were created in Venezuela and Bolivia. And whereas mobilization in Bolivia comes mostly from the bottom up, in Venezuela and Ecuador it comes from the top-down. To compare their divergent patterns this paper analyses: 1 the strength of subaltern organizations when these leaders were elected; 2 the confrontation between governments and the oppositions; and 3 the views of democratization of the coalitions that brought these regimes to power.Resumen: En nombre del pueblo: democratización, organizaciones populares y populismo en Venezuela, Bolivia y EcuadorLos regímenes de Hugo Chávez, Evo Morales y Rafael Correa atentan en contra del pluralismo a la vez que incluyen materialmente a los pobres y a los excluidos. Estos regímenes que por lo general son aglutinados en un mismo saco tienen diferentes patrones para promover la participación política. Es así que mientras que en Ecuador la participación se reduce a votar en elecciones, en Venezuela y Bolivia se crearon instituciones participativas. Mientras que en Bolivia la participación viene en gran medida desde las bases, en Ecuador y Venezuela viene desde arriba hacia abajo. Para comparar los diferentes patrones este trabajo estudia: 1 la fuerza de organizaciones de los subalternos cuando estos líderes fueron electos; 2 la confrontación entre el gobierno y las oposiciones; 3 las visiones sobre democratización de las coaliciones que llevaron al poder a estos líderes.

    In the year of 2003 the Brazilian government, as form of to stimulate the demand for natural gas in the country and to promote the success of the investment accomplished in the construction of the pipe line Bolivia-Brazil, it lowered the price of the Bolivian commodity' in US$0,85/MMBTU. In the end of 2005 and mainly in 2006, the current Bolivian president Evo Morales nationalized the energy reservations of your country. To main change it is related to the price of sale of the Bolivian input. The values stipulated in contract they were broken and new negotiations are in process. The maximum capacity of transport of natural gas was reached in 2007. However, before the crisis established due to the measure taken by the government from Bolivia, Brazil suspended the investments in compressors and the projections of increase of this capacity were stagnated. One of the forecasts was to increase in at least more 50% of the current capacity or even in 100% in a more promising scenery. Before this context this research makes the analysis of economical viability regarding the construction of the pipe line Bolivia-Brazil in agreement with three sceneries. The first of them suggests that the investments foreseen in compressors it was stopped and, this way, the pipe line will operate it ties the end of the amortization with your current maximum capacity. The second scenery already suggests that the investments were not interrupted, in other words, the current maximum capacity was overcome in 50%. Similarly to the previous ones, the third scenery makes reference the overrun of the current capacity in 100%. The methodology used for such an analysis it was lent of the financial mathematics and it is treated of the calculation of TIR and of VPL. Both studies show that in agreement with TIR (15%) and VPL the economical viability is satisfactory. The president of PETROBRAS is renegotiating the contract and the investments will probably be retaken. This measured it seeks to

METHODS: To assess the magnitude and reasons for occupational pesticide intoxication, a cross-sectional study with interviews and blood-tests was performed among 201 volunteer farmers ......, and a coordinated action by authorities, society and international bodies is needed to limit the number of intoxications and the environmental pollution....... with spraying operations. The risk of experiencing symptoms and the serum cholinesterase activity were influenced by whether or not organophosphates were used and the number of times sprayed. The experience of symptoms was moreover influenced by the hygienic and personal protective measures taken during...... spraying operations while this had no influence on the serum cholinesterase level. CONCLUSION: The study showed that occupational pesticide intoxications were common among farmers and did depend on multiple factors.

    Full Text Available From Enron to Evo is a long-term study of Enron and Shell’s construction of the Cuiabá pipeline in eastern Bolivia. The pipeline goes through the middle of the Chiquitano forest and affects a population of about 8,000. The project also has a negative impact on four critical ecoregions; the Gran Chaco and Cerrado, which are a mixture of grasslands and scattered trees, the Chiquitano dry forest, and the Pantanal wetlands. The Cuiabá pipeline has been highly contested by the thirty-four Chiquitano and two Ayoreo communities that live in the area. After years of field research, extensive interviews and document analyses, Dr. Hindery manages to expose the murky ways in which the hydrocarbon industry works in Bolivia. This is an industry where the powerful –mainly multinational oil companies and the Bolivian government– abuse the ecoregion and the indigenous populations that live on it.

    Full Text Available This paper presents an anthropogenetic study of African descent populations in the region of Nor Yungas, Bolivia. Emphasis is placed on the socio-historical frame, the methodology that was built with communities and participants, and the importance of returning results to the community. Our proposal was to bring a scientific tool that would be a contribution to the historical-cultural reconstruction of ancestral roots undertaken by the Afro-Bolivian communities for the last two decades, in pursuit of a greater visibility as a nation in the Plurinational State of Bolivia. Uniparental inheritance of genetic markers (mtDNA and Y chromosome STRs were determined in order to estimate the geographic origin of the population. The results show that communities studied have a strong African descent, with a minoritary process of interbreeding with Native American and European.

Un aspecto de estas dificultades fue la aparición de discursos nacionalistas y regionalistas, los cuales dividían la parte oriental de la parte occidental del país, y al revés. Dichos discursos se han caracterizado por sus fuertes matices étnicos y acentuaban por un lado la identidad camba y por otro la identidad colla. No obstante, tales discursos tienen raíces muy distintas y reflejan proyectos y relaciones de clase muy diferentes. Partiendo de la metáfora de la «nevera al revés» (la nevera que genera calor hacia dentro y frío hacia afuera, este artículo busca elucidar la interrelación entre la política nacionalista/regionalista, la etnia y la clase social en la Bolivia contemporánea.ABSTRACT: Over the past years Bolivia has seen a series of «social convulsions». One aspect of these upheavals was the emergence of nationalist and regionalist discourses pitting the orient against the occident of the country, and vice versa. Such discourses were marked by strong ethnic overtones, accentuating either camba or colla identities. Nevertheless, such identity discourses have very different roots and reflect very different projects and class relations. Taking a lead from the «inverted fridge» metaphor –the fridge that generates warmth towards the «inside(r» and cold towards the «outside(r»– this paper seeks to elucidate the interrelation between the politics of nationalism/regionalism, ethnicity and class in contemporary Bolivia.

This paper reports on programmes in Bolivia, Kenya, and South Africa. All three countries have established antenatal syphilis control programmes. Early antenatal syphilis screening and management of positive cases were difficult to implement since most women presented for their first antenatal clinic visit after 6 months of pregnancy. Most women...

    To establish the frequency of necrotizing funisitis in congenital syphilis, we conducted a prospective descriptive study of maternal syphilis in Bolivia by testing 1,559 women at delivery with rapid plasma reagin (RPR). We examined umbilical cords of 66 infants whose mothers had positive RPR and fluorescent treponemal antibody absorption tests. Histologic abnormalities were detected in 28 (42%) umbilical cords (seven [11%] had necrotizing funisitis with spirochetes; three [4%] had marked funi...

    2009-01-01

    The global financial crisis (GFC) has had a negative effect on the Bolivian economy. The outbreak of the GFC has caused a drop in export commodity prices such as mining and hydrocarbons, and a reduction in remittances. Bolivia however, was in a relatively good position to deal with the negative effects of the GFC. The country has experienced in recent years an important commodity price boom, which significantly increased external revenues, public and private incomes and consumption levels. Al...

  5. Stereo Pair with ASTER Image, Iturralde Structure, Bolivia

    Science.gov (United States)

    2002-01-01

    An 8-kilometer (5-mile) wide crater of possible impact origin is shown in this stereoscopic view of an isolated part of the Bolivian Amazon. The view is derived from an Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) satellite image and a Shuttle Radar Topography Mission (SRTM) elevation model. The circular feature covering much of the image, known as the Iturralde Structure, is possibly the Earth's most recent 'big' impact event recording collision with a meteor or comet that might have occurred between 11,000 and 30,000 years ago.Although the structure was identified on satellite photographs in the mid-1980s, its location is so remote that it has only been visited by scientific investigators twice, most recently by a team from NASA's Goddard Space Flight Center in September 2002. Lying in an area of very low relief, the landform is a quasi-circular closed depression only about 20 meters (66 feet) in depth, with sharply defined sub-angular 'rim' materials. It resembles a 'cookie cutter' in that its appearance 'cuts' the heavily vegetated soft-sediments and pampas of this part of Bolivia. The SRTM data have provided investigators with the first topographic map of the site and will allow studies of its three-dimensional structure crucial to determining whether it actually is of impact origin.This stereoscopic image was generated by first draping the ASTER satellite image over the Shuttle Radar Topography Mission digital elevation model. Two differing perspectives were then calculated, one for each eye. They can be seen in 3-D by viewing the left image with the right eye and the right image with the left eye (cross-eyed viewing) or by downloading and printing the image pair and viewing them with a stereoscope. When stereoscopically merged, the result is a vertically exaggerated view of Earth's surface in its full three dimensions.Thick vegetation in part defines the surface that the SRTM radar sees as it maps the terrain.

    Full Text Available Unregulated selling practices, bad storage habits and the use of illegal pesticides in Bolivia are widespread, with increasing negative consequences on public health and the environment. The present study describes the selling, storage and use of legal, illegal and obsolete pesticides among pesticide retailers and farmers in Bolivia. A cross-sectional study was conducted on 191 pesticide-using farmers and 40 pesticide retailers. Data were gathered in 2009 in La Paz County, Bolivia. A questionnaire was used to evaluate pesticide handling practices and observational data on pesticide stocks and storage was assessed through direct visits on site. Banned, outdated and highly toxic pesticides were found stored on most smallholder farms. A mean of 299 g of pesticides was found on each farm, of which 60% were obsolete. Knowledge on pesticide toxicity and safe handling practices were lacking among both retailers and farmers, and poisonings were frequently reported. Significant figures of obsolete pesticides were found outside of the officially recognized dumping sites. This underlines the necessity of including the small but numerous amounts of pesticides stored at farms, when calculating a country’s total amount of obsolete pesticides. Better regulations of imports, sale and storage and an improved use of safety measures when handling pesticides needs to be urgently addressed.

    Full Text Available It is intended to reflect, from the history of the people Chiquitano, originally a set of more than twenty ethnic groups that were aldeadas by Jesuits in the Chiquitos mission, elements of contemporary identity and ethnicity. The proposal presented is to understand how identities are situated today relating to the territoritalities experienced in Bolivia and Brazil, since these people are currently split because the division of national states. The fact that they live in one country or in another causes different experiences and propositions of identity. However, until the 1980s the frontier between the two countries was not yet fully institutionalized, and it was possible a transit to and fro, and this freedom allowed maintenance of social relations and kinship networks. How are the identities currently in territorial diversity and historical? How they configure their territoritalities Chiquitanos in Bolivia and Brazil if the indigenous policies are different? How the self-identifications occur if there are different concepts for "Indians" - here and Bolivia indigenous "peasant" or "pueblos originales"? How the official recognition of ethnicity in Brazil Chiquitanos brought new elements that caused conflicts? These are questions we intend to answer in this paper.

    2011-03-01

    Here we report a superbly preserved and profusely represented five-ichnotaxa dinosaur track assemblage near Icla village, 100 km southeast of Sucre, Bolivia. As preserved in reddish Jurassic-Cretaceous boundary aeolian sandstones, this rich and uncommon assemblage is, additionally, the oldest dinosaur tracksite for Bolivia. Four trackmakers were identified in the area: three quadrupedal and one bipedal, all of them with tracks of around 35 cm in lenght. One of the quadrupedals is represented by no less than five adult individuals (ichnotaxon A), and four purported juveniles (ichnotaxon B) walking in association. The other two quadrupedals (ichnotaxa C and D) involve four trackways, and the last, the bipedal trackmaker (ichnotaxon E), is represented by one trackway. The five ichnotaxa represented in the "Palmar de Tunasniyoj" could be tentatively assigned to the following trackmakers: Ichnotaxa A and B are assigned to basal stegosaurians; ichnotaxon C to a basal tyreophoran, perhaps related to the ankylosaur lineage; ichnotaxon D to the Ankylosauria, and ichnotaxon E to Theropoda. The Tunasniyoj assemblage, the oldest dinosaur tracksite for Bolivia, includes the oldest known evidence assigned to ankylosaurs and stegosaurs for South America.

    Full Text Available This article examines the implications of natural gas developmentfor Guaraní indigenous communities in southeastern Bolivia. Duringthe 1990s, the Bolivian government enacted a series of neoliberalreforms designed to attract international investment for natural gasand petroleum exploitation and to facilitate the export of hydrocarbons.Protests over the management and distribution of the benefitsderived from natural gas contributed diretly to the election of EvoMorales, Bolivia´s first indigenous president. Nevertheless, anddespite the pro-indigenous discourse of Morales and his MAS (Movementto Socialism party, gas production has had negative effectsfor indigenous peoples in Bolivia´s Chaco region, who are directlyimpacted by extractive activities.

    Full Text Available Young adults 18 to 25 years old show the highest prevalence of marijuana use in Latin America. This study analyzes the changes in prevalence of marijuana use among university students in the Andean Community (Bolivia, Colombia, Ecuador, and Peru from two studies carried out in 2009 and in 2012. Data were collected through representative two-stage samples of universities and students in the Andean Community. An online survey was administered using a standardized questionnaire. Prevalence was calculated for lifetime, past year, and past month. Marijuana was the most widely used illicit substance consumed among university students, in 2009 and in 2012. Past month prevalence among university students in 2009 in Colombia was 5.27%, in Peru 1.00%, in Ecuador 1.68%, and in Bolivia 0.76%. Past month prevalence in 2012 in Colombia was 7.14%, in Ecuador 3.67%, in Peru 1.62%, and in Bolivia 1.45% in 2012. Among university students in the Andean Community, past month prevalence increased among both males and females between 2009 and 2012 in most countries. Marijuana continues to be the most commonly used illicit drug in Latin American countries. Increases in prevalence among young adults could have important implications for national drug policy.

    Indigenous peoples have the worst socio-demographic indicators and the largest inequalities in terms of access to social services and health in the Latin American region, Bolivia included. In the last few years, attempts to implement policies that support indigenous people's health rights led to the development of intercultural health approaches. Yet, acceptance and integration of indigenous medicine into the biomedical health system presents a major challenge to intercultural health in Latin America. The objective of this article is to analyze the case of a health center in Tinguipaya, one of the first and few examples of intercultural health initiatives in Bolivia. This intercultural health project, which represents a pioneer experience with regard to the creation of intercultural health services in Bolivia, aims to create a network between local communities, traditional healers, and biomedical staff and offer a more culturally sensitive and holistic health service for indigenous people living in the area. The aim of this article is to critically assess this initiative and to analyze the main challenges met in the creation of a more effective intercultural health policy. The extent to which this initiative succeeded in promoting the integration between indigenous health practitioners and biomedical staff as well as in improving access to health care for local indigenous patients will also be examined.

    Full Text Available Using data on informal market loans in the Cochabamba region of Bolivia, we test the hypothesis that monetary reform in the 1985-87 period resulted in a dedollarization of the economy. A theoretical model of the loan market suggests variables to be examined in the empirical analysis. A PROBIT model of the probability of dollar-denominated loans is estimated as a function of Bolivian inflation, exchange-rate depreciation, and exchangerate volatility. In addition, policy reforms are modeled with dummy variables that switch on at the date of the reforms. In addition to the PROBIT estimates, we aggregate monthly average time series data for the informal market and investigate the hypotheses studied in this alternative data set.The evidence from the informal loan market suggests that the Bolivian stabilization plan was associated with an increase in dollarization rather than a decrease. Several possible reasons for this result are discussed, including a lack of credibility of the announced plan. Dolarization and Monetary Reform. Evidence from the Cochabamba Region of Bolivia

    The Bolivia-Brazil Natural Gas Pipeline has 2.593 kilometers since Rio Grande City in Bolivia until Canoas City, in south Brazil. The pipeline crosses a lot of types of geological fields and difficult topography. The south spread of the gas pipeline is the most interesting because of its hard topography combined with the variety of geological materials, such as, colluvium deposits and debris flow areas. Curriola River is located at the kilometer 408, north part of Parana State. In this area, the pipeline crosses slopes of 45 degrees of inclination. The down part of Curriola's slope is composed by a non-resistance material (clay and little rock blocks) with a high porosity. Every year, during the rainy seasons, tension cracks are observed evidencing the earth movement. The slope stability is above the minimum expected for pipeline operation. The aim of this paper is to present the site characterization of the Curriola River Slope, together with all the investigation made in order to supply the studies with condensed information for the slope stabilization.

    Full Text Available This essay relates improvements in social indicators in Bolivia during the Twentieth Century to ideological changes during the same period. During the Twentieth Century, most social indicators improved dramatically in Bolivia. Separately, scholars have vigorously debated ideologies, such as neoliberalism and its macroeconomic competitors, and the potential social impact of these ideologies. Despite the separate emphases on ideas and social outcomes, no systematic attempt has been made by scholars of Bolivia to link long–term ideological change to long–term social improvement in the country. This essay argues that it is probable that such a relationship exists, but it is important to consider mass ideology, which affects the whole of Bolivian society, in addition to elite ideology, which affects a much more limited portion of society.Este ensayo relaciona las mejoras en indicadores sociales en Bolivia durante el siglo XX con cambios ideológicos registrados durante el mismo periodo. Durante el siglo XX la mayoría de los indicadores sociales mejoraron dramáticamente en Bolivia. Los especialistas han debatido vigorosamente  la relación de estas mejoras con ideologías tales como el neoliberalismo y sus competidores macroeconómicos, discutiendo su potencial impacto social. Sin embargo, pese al énfasis otorgado a la relación de las ideas con los resultados sociales, no ha habido ninguna tentativa sistemática por parte de los especialistas de  relacionar el cambio ideológico de largo plazo con las mejoras sociales de largo plazo en el país. Este ensayo sostiene que es probable que tal relación exista, pero para visibilizarla es importante considerar la ideología de masas, que afecta al conjunto de la sociedad boliviana, además de la ideología de la élite, que afecta a una porción mucho más limitada de la sociedad.

    The analysis of drainage net allows to identify features of relief symmetry and/or not symmetry and know its morpho structure (high and low structural). The interpretation of relief and drainage texture elements at Landsat/ETM7+ satellite images allows to identify the geo environmental zoning. The integration between morpho structural maps and geo environmental zones maps produces sustainable capacity maps. In the Bolivia-Brazil Gas Pipeline influence area, the evaluation of sustainable capacity shapes the interrelation among gas pipeline and physical environment and allows classify more geological and geotechnical favorable areas to gas pipeline maintenance. Gas pipeline regions located at 'High Sustainable Capacity' need few maintenance. However, gas pipeline regions at 'Low/Very Low Sustainable Capacity' need constant investment and monitoring.

    Herein, we describe Litomosoides salazari n. sp. collected from the body cavity of the yellow bat, Lasiurus ega , from Bolivia. This new species of filarioid nematode is most closely related to the carinii group and is characterized by its relatively small size with the vulva located slightly posterior to the esophago-intestinal junction; an arrow-shaped buccal capsule; and a short, rounded tail. New host and locality records for both Litomosoides hamletti and L. chandleri in phyllostomid bats, and L. brasiliensis occurring in both phyllostomid and vespertilionid bats, are provided. The morphological variability of the specimens is documented by providing comparative measurements of 3 known species. Litomosoides brasiliensis occurs in 6 species of bats from Bolivia and was the most common species of filarioid nematode encountered. All 4 species of nematodes, including the new species, were found in sympatry at Chijchijpa, a locality in the Yungas of Bolivia. PMID:20738202

    Wild populations of Triatoma infestans, the main vector of Chagas disease in the Southern Cone countries, may be involved in reinfestation of human dwellings, limiting the success of vector-control campaigns in Bolivia. Knowledge of the distribution of these populations remains incomplete. We report here the detection of T. infestans wild populations in large areas in the department of La Paz, Bolivia. Among 18 sylvatic areas investigated, 17 were positive with T. infestans specimens. The infection rate of captured T. infestans with Trypanosoma cruzi was 85.7% in adult specimens. These results expand the geographical distribution of wild populations of T. infestans; it may be distributed throughout the Inter-Andean Dry Forest eco-region of Bolivia. The current information allows us to propose the hypothesis that a sylvatic origin of the reinfestation is located in the valleys of La Paz. PMID:20348501

    2016-03-01

    Full Text Available By the late 20th and early 21st century, credit institutions in Bolivia had become more complex, resilient and popular that at any time previously in its history. Traditional economics analyses emphasize incentives created by laws such as those promulgated by the Kemmerer mission in Bolivia in the 1920s and 30s, or material factors, such as transportation costs. Yet neither of these explanations offers a compelling explanation for the magnitude of the flourishing of popular and complex credit institutions in Bolivia after the 1960s. Cultural changes, however, might offer a compelling complement to legal and material explanations of credit development. Vatican II represented an important mass change in Bolivian culture, and institutions associated with these reforms ushered in a new era of credit institution development in the country. A finales del siglo XX y comienzos del XXI, las instituciones crediticias en Bolivia se volvieron más complejas, elásticas y populares que en cualquier otro momento de su historia. Los análisis económicos tradicionales ponen de relieve los incentivos creados por leyes como las promulgadas por la misión Kemmerer en Bolivia en las décadas de 1920 y 1930, o factores materiales, tales como los costos de transporte. Con todo, ninguna de estas explicaciones ofrece una explicación convincente de la importancia del florecimiento de instituciones crediticias populares y complejas en Bolivia después de la década de 1960.  No obstante, los cambios culturales podrían ofrecer un complemento de peso a las explicaciones legales y materiales del desarrollo del crédito. El Concilio Vaticano II representa un importante cambio en la cultura boliviana, y las instituciones asociadas con sus reformas marcan el comienzo de una nueva era en el desarrollo de la institución crediticia en el país.

    Full Text Available For most crops, like Capsicum, their diversity remains under-researched for traits of interest for food, nutrition and other purposes. A small investment in screening this diversity for a wide range of traits is likely to reveal many traditional varieties with distinguished values. One objective of this study was to demonstrate, with Capsicum as model crop, the application of indicators of phenotypic and geographic diversity as effective criteria for selecting promising genebank accessions for multiple uses from crop centers of diversity. A second objective was to evaluate the expression of biochemical and agromorphological properties of the selected Capsicum accessions in different conditions. Four steps were involved: 1 Develop the necessary diversity by expanding genebank collections in Bolivia and Peru; 2 Establish representative subsets of ~100 accessions for biochemical screening of Capsicum fruits; 3 Select promising accessions for different uses after screening; and 4 Examine how these promising accessions express biochemical and agromorphological properties when grown in different environmental conditions. The Peruvian Capsicum collection now contains 712 accessions encompassing all five domesticated species (C. annuum, C. chinense, C. frutescens, C. baccatum, and C. pubescens. The collection in Bolivia now contains 487 accessions, representing all five domesticates plus four wild taxa (C. baccatum var. baccatum, C. caballeroi, C. cardenasii, and C. eximium. Following the biochemical screening, 44 Bolivian and 39 Peruvian accessions were selected as promising, representing wide variation in levels of antioxidant capacity, capsaicinoids, fat, flavonoids, polyphenols, quercetins, tocopherols, and color. In Peru, 23 promising accessions performed well in different environments, while each of the promising Bolivian accessions only performed well in a certain environment.

    BACKGROUND In Bolivia, in 2008, the under-five mortality rate is 54 per 1000 live births. Diarrhea causes 15% of these deaths, and 40% of pediatric diarrhea-related hospitalizations are caused by rotavirus illness (RI). Rotavirus vaccination (RV), subsidized by international donors, is expected to reduce morbidity, mortality, and economic burden to the Bolivian state. Estimates of illness and economic burden of RI and their reduction by RV are essential to the Bolivian state’s policies on RV program financing. The goal of this report is to estimate the economic burden of RI and the cost-effectiveness of the RV program. METHODS To assess treatment costs incurred by the healthcare system, we abstracted medical records from 287 inpatients and 6,751 outpatients with acute diarrhea between 2005 and 2006 at 5 sentinel hospitals in 4 geographic regions. RI prevalence rates were estimated from 4 years of national hospital surveillance. We used a decision-analytic model to assess the potential cost-effectiveness of universal RV in Bolivia. RESULTS Our model estimates that, in a 5-year birth cohort, Bolivia will incur over US$3 million in direct medical costs due to RI. RV reduces, by at least 60%, outpatient visits, hospitalizations, deaths, and total direct medical costs associated with rotavirus diarrhea. Further, RV was cost-savings below a price of US$3.81 per dose and cost-effective below a price of US$194.10 per dose. Diarrheal mortality and hospitalization inputs were the most important drivers of rotavirus vaccine cost-effectiveness. DISCUSSION Our data will guide Bolivia’s funding allocation for RV as international subsidies change. PMID:21624421

Four steps were involved: 1) Develop the necessary diversity by expanding genebank collections in Bolivia and Peru; 2) Establish representative subsets of ~100 accessions for biochemical screening of Capsicum fruits; 3) Select promising accessions for different uses after screening; and 4) Examine how these promising accessions express biochemical and agromorphological properties when grown in different environmental conditions. The Peruvian Capsicum collection now contains 712 accessions encompassing all five domesticated species (C. annuum, C. chinense, C. frutescens, C. baccatum, and C. pubescens). The collection in Bolivia now contains 487 accessions, representing all five domesticates plus four wild taxa (C. baccatum var. baccatum, C. caballeroi, C. cardenasii, and C. eximium). Following the biochemical screening, 44 Bolivian and 39 Peruvian accessions were selected as promising, representing wide variation in levels of antioxidant capacity, capsaicinoids, fat, flavonoids, polyphenols, quercetins, tocopherols, and color. In Peru, 23 promising accessions performed well in different environments, while each of the promising Bolivian accessions only performed well in a certain environment. Differences in Capsicum diversity and local contexts led to distinct outcomes in

    A case of hantavirus pulmonary syndrome (HPS) was serologically confirmed in a critically ill patient in Santiago, Chile. The patient's clinical course had many similarities to that of other HPS patients in North and South America but was complicated by acute severe renal failure. The patient's history included self-reported urban and probable rural rodent exposure during travel in Bolivia. Comparison of a viral sequence from an acute-phase serum sample with other known hantaviruses showed that the hantavirus nucleic acid sequence from the patient was very similar to a virus recently isolated from rodents associated with HPS cases in Paraguay.

    Lack of housing is a problem in Bolivia, migrations from rural areas to towns causes problems in the fast growing cities. Since urban planning does not have the resources to keep up with the need for housing many settlements are illegal and often lead to a land use conflict. In some cities large parts of the population live in spontaneous settlements, often in areas planned for another use of land. In Cochabamba the number of inhabitants has grown rapidly, particularly in the past few decades...

    The author has identified the following significant results. Due to the receipt of ERTS-1 imagery, Bolivia will have for the first time a geomorphological map at a scale of 1:100,000. Now the researcher and the student will be able to compare the distribution of the existing shapes of the country, which have been modelled by diverse processes, factors, and agents. This geomorphological information will be very useful in its application to mining, especially alluvial beds, engineering work, and other geological studies. This map is divided into ten geomorphological units which coincide with the geostructural units of the western region of the country.

    2010-10-01

    Full Text Available This study examined environmental and socioeconomic outcomes of a water project in rural Bolivia, and sought insights on how and why its planning was so flawed. The project destroyed an ancient, sustainable irrigation system, and replaced it with one that provides insufficient and diminishing quantities of water to many fewer people, appears to be causing land degradation and groundwater depletion, and has fueled conflicts. The study shows that even relatively small, NGO-led projects can generate significant negative impacts, and raises questions about the pressures on development agencies to charge ahead with projects, despite obvious potential for such impacts.

    Two filarioid nematodes, Litomosoides andersoni n. sp. and Litomosoides ctenomyos n. sp. (Nemata: Onchocercidae), are described from the mesenteries of the subterranean rodent Ctenomys opimus (Rodentia: Hystrichognathi) collected on the altiplano of Bolivia. Specimens collected near Rancho Huancaroma (Oruro Dept.) in 1984 and 1986 can be recognized as undescribed by the structures of the spicules and stoma and the shape of the ovijector. This record represents the first time members of the genus Litomosoides have been recovered from rodents of the family Ctenomyidae; this also represents the first published report of these nematodes from mammals in Bolivia.

    Full Text Available A small focus of hemorrhagic fever (HF cases occurred near Cochabamba, Bolivia, in December 2003 and January 2004. Specimens were available from only one fatal case, which had a clinical course that included fever, headache, arthralgia, myalgia, and vomiting with subsequent deterioration and multiple hemorrhagic signs. A non-cytopathic virus was isolated from two of the patient serum samples, and identified as an arenavirus by IFA staining with a rabbit polyvalent antiserum raised against South American arenaviruses known to be associated with HF (Guanarito, Machupo, and Sabiá. RT-PCR analysis and subsequent analysis of the complete virus S and L RNA segment sequences identified the virus as a member of the New World Clade B arenaviruses, which includes all the pathogenic South American arenaviruses. The virus was shown to be most closely related to Sabiá virus, but with 26% and 30% nucleotide difference in the S and L segments, and 26%, 28%, 15% and 22% amino acid differences for the L, Z, N, and GP proteins, respectively, indicating the virus represents a newly discovered arenavirus, for which we propose the name Chapare virus. In conclusion, two different arenaviruses, Machupo and Chapare, can be associated with severe HF cases in Bolivia.

    Despite increasing awareness that domestic violence is a major public health problem, existing studies focus on physical and sexual violence and give little attention to psychological violence. This study uses data from the 2008 Bolivia Demographic and Health Surveys (BDHS) to examine the prevalence and correlates of physical, sexual, and psychological intimate partner violence in Bolivia. The results show that psychological intimate partner violence is extremely common (affecting nearly one in two women) and often occurs in addition to physical violence. While physical, psychological and sexual intimate partner violence have several common predictors, there are factors that only affect some types of violence. Common risk factors include urban residence, respondent's employment status and having witnessed interparental violence in childhood. Although marital status is not a risk factor for physical violence, unmarried cohabitation is a strong risk factor for psychological intimate partner violence. Our findings highlight the need for research to assess the potential consequences of psychological intimate partner violence, particularly for women's mental health. PMID:23534436

    1975-01-01

    Fascioliasis caused by Fasciola hepatica was a serious problem for sheep and alpacas in the Altiplano Region of Bolivia. In some provinces close to Lake Titicaca, the raising of sheep was forced to discontinue, because infection with the fluke made it unprofitable and almost impossible. It was proved that in the Altiplano Region, two species of freshwater snails, Lymnaea viatrix and L. cubensis var., served as intermediate hosts for F. hepatica. In some subtropical areas of Bolivia, these snails could not be found, although other Lymnaea sp. was widely distributed there. As it is possible for Lymnaea sp. to be intermediate host for the fluke, further studies are required on the identification. Acute fascioliasis of sheep occurred in the Altiplano Region principally during a period from May to July, or the dry season. In some areas, the mortality rate of infected sheep was roughly estimated as 15 to 25% annually. Contamination with Fasciola metacercariae of herbage and semi-aquatic plants grown in a swamp in one of these areas was biologically assessed, using guinea pigs. Plants of Compositae and Eleocharis sp. were contaminated most intensely and those of Senicio sp. and Vallisneria sp. carried a fairly large number of cysts, while plants of Scirpus sp. and Ranunclaceae carried only a few cysts. No signs of Fasciola infection were observed in any animal given the plants of Liliaceae.

  9. Tenure Security and Land Appropriation under Changing Environmental Governance in Lowland Bolivia and Pará

    Directory of Open Access Journals (Sweden)

    Pablo Pacheco

    2015-02-01

    Full Text Available Appropriation of public lands associated with agricultural frontier expansion is a longstanding occurrence in the Amazon that has resulted in a highly skewed land-tenure structure in spite of recent state efforts to recognize tenure rights of indigenous people and smallholders living in or nearby forests. Growing concerns to reduce environmental impacts from agricultural development have motivated state governments to place greater attention on sustainable land management and forest conservation. This paper assesses the political and institutional conditions shaping tenure security and land appropriation in lowland Bolivia and the State of Pará in Brazil, and their links with environmental governance. The two cases show that clarifying and securing tenure rights is considered as the cornerstone for improving environmental governance. Thus, much attention has been given to the recognition of indigenous people and smallholder rights and to legalization of large-scale estates in agricultural frontiers, which have in turn influenced emerging conservation and environmental governance approaches. While policy frameworks share similar goals in the two cases, contrasting implementation approaches have been adopted: more agrarian in lowland Bolivia and more conservationist in the State of Pará.

    Summary Objectives Rotavirus is the most important etiology of severe diarrhea in Bolivia. The monovalent attenuated human oral rotavirus vaccine Rotarix® was introduced in Bolivia in 2008. We describe the molecular epidemiology of circulating rotavirus strains before vaccine introduction. Methods Two thousand one hundred thirty-five diarrheal samples were collected from hospitals in four Bolivian cities during 2007–2008. Forty-three percent (445 of 1030 rotavirus-positive samples) were analyzed for G and P genotypes. Among those, 331 were electropherotyped by polyacrylamide gel electrophoresis. Disease severity was quantified using a modified Vesikari scale. Results Among the 445 samples, five genotypes were found to be prevalent: G9P[8] (33%), G1P[6] (17%), G2P[4] (13%), G9P[6] (12%), and G1P[8] (4%). Co-infections with two or more strains accounted for 14% of samples. The most prevalent strain, G9, showed greater electropherotype diversity compared to other serogroups. Strain G1P[6] generally infected younger children and peaked later in the year than other strains. No particular genotype was associated with a higher severity score, though there was a significant difference in the duration of diarrhea between genotypes. Conclusions During the 2-year pre-vaccine period, substantial diversity of rotavirus co-circulating strains was observed. These data constitute a baseline against which changes in circulating strains post-vaccine introduction can be monitored. PMID:23688547

  12. Deformation, deposition, and surface uplift in the hinterland of the Central Andes, Bolivia

    2011-12-01

    Paleoelevation histories from mountain belts like the Central Andes of Bolivia provide important constraints on the timing and geodynamic mechanisms associated with surface uplift. New stable isotope data from paleosol carbonate nodules in the Altiplano and Eastern Cordillera of the Central Andes of Bolivia indicate a previously undocumented episode of surface uplift occurred in the region between ca. 24 and 17 Ma. Oxygen isotope and clumped-isotope thermometry values from paleosol carbonate in strata >24 Ma suggest paleoelevations as low as sea-level. Paleosol carbonate in strata ca. 17 Ma have oxygen isotope and clumped-isotope thermometry values, which using modern lapse rates, indicate an increase in elevation of approximately 3 km. Relatively undeformed Oligocene and Miocene strata overlap faulted Paleozoic rocks of the Bolivian Eastern Cordillera, indicating deposition and surface uplift post-dated and was decoupled from upper crustal deformation. Together, geological data from the area record an initial period of deformation and exhumation, a subsequent period of sediment deposition and overlap, and then an episode of surface uplift that was not accompanied by upper crustal deformation. We propose accommodation for the Oligocene-Miocene strata was associated with mantle and lowermost crustal processes, and the subsequent increase in surface elevation was an isostatic response to removal of dense material through delamination or drip. Combined with existing data sets in the Central Andes, these new data suggest multiple, regionally-variable, and diachronous periods of surface uplift occurred within the Central Andes during the Cenozoic Era.

  13. A model for predicting the growth of Eucalyptus globulus seedling stands in Bolivia

    2012-11-01

    Eucalyptus globulus is one of the most planted species in the Inter-Andean Valleys of Bolivia, where growing conditions are different from most places where eucalyptus have been studied. This prevents a straightforward utilization of models fitted elsewhere. In this study a distance-independent individual-tree growth model for E. globulus plantations in Bolivia was developed based on data from 67 permanent sample plots. The model consists of sub-models for dominant height, tree diameter increment, height-diameter relationship and survival. According to model-based simulations, the mean annual increment with the optimal rotation length is about 13 m3 ha{sup -}1 yr{sup -}1 on medium-quality sites and 18 m{sup 3} ha{sup -}1 yr -1 on the best sites. A suitable rotation length for maximizing wood production is approximately 30 years on medium sites and 20 years on the most productive sites. The developed models provide valuable information for further studies on optimizing the management and evaluating alternative management regimes for the species. (Author) 22 refs.

La expropiación mexicana de 1938 alcanzó una dimensión trasnacional más allá de sus repercusiones diplomáticas: una experiencia percibida bajo muy diversos prismas en cada país latinoamericano. ¿Cómo fue vista la expropiación mexicana en los Andes bolivianos? Se argumenta que en la Paz, y en Sucre, diversos sectores de la sociedad leyeron esa expropiación tras los filtros del conflicto con la Standard Oil of Bolivia y del debate ideológico y político en torno a la recién creada YPFB, y cargaron de otro significado este episodio nacionalista al adaptarlo al contexto boliviano, dialogando simultáneamente con el sustrato previo de recepción de la revolución mexicana en la región, así como con el especial contexto político, económico y diplomático andino. Razones de orden nacional e internacional explican las reacciones ante el episodio petrolero mexicano en Bolivia, tanto como la percepción de estas por parte de la diplomacia mexicana.This article deals with a relevant subject in Latin American historiography, that being the Mexican oil expropriation during the Lázaro Cárdenas government and provides original information as well as an innovative approach that goes beyond strictly national historiographies, with the intention of contributing both to Bolivian and Mexican history. The Mexican expropriation of 1938 reached a transnational dimension beyond its diplomatic implications; an experience perceived through quite different prisms in each Latin American country. How was the Mexican expropriation viewed in the Bolivian Andes? We have argued that in La Paz and Sucre, various

    Patricia V Aguilar

    Full Text Available Venezuelan equine encephalitis virus (VEEV has been responsible for hundreds of thousands of human and equine cases of severe disease in the Americas. A passive surveillance study was conducted in Peru, Bolivia and Ecuador to determine the arboviral etiology of febrile illness. Patients with suspected viral-associated, acute, undifferentiated febrile illness of <7 days duration were enrolled in the study and blood samples were obtained from each patient and assayed by virus isolation. Demographic and clinical information from each patient was also obtained at the time of voluntary enrollment. In 2005-2007, cases of Venezuelan equine encephalitis (VEE were diagnosed for the first time in residents of Bolivia; the patients did not report traveling, suggesting endemic circulation of VEEV in Bolivia. In 2001 and 2003, VEE cases were also identified in Ecuador. Since 1993, VEEV has been continuously isolated from patients in Loreto, Peru, and more recently (2005, in Madre de Dios, Peru. We performed phylogenetic analyses with VEEV from Bolivia, Ecuador and Peru and compared their relationships to strains from other parts of South America. We found that VEEV subtype ID Panama/Peru genotype is the predominant one circulating in Peru. We also demonstrated that VEEV subtype ID strains circulating in Ecuador belong to the Colombia/Venezuela genotype and VEEV from Madre de Dios, Peru and Cochabamba, Bolivia belong to a new ID genotype. In summary, we identified a new major lineage of enzootic VEEV subtype ID, information that could aid in the understanding of the emergence and evolution of VEEV in South America.

    Tailings from mining activities in Bolivia represent an environmental problem. In the vicinity of the tin mines of Llallagua, Potosi department, there are large dumps and tailings. We present a study of the use of these wastes as raw materials for the manufacture of glass. This procedure aims to contribute to environmental remediation of mining areas through the vitrification, a process which offers an alternative for stabilization of hazardous waste. In addition, the marketing of the obtained product would provide an additional income to the mining areas. For this study three samples of mining waste, with grain size between sand and silt, were used. The chemical composition of these raw materials, determined by X-ray fluorescence, is granitic, with high contents of heavy metals. On the basis of its composition, glass were made from silica glass by adding CaCO{sub 3} and Na{sub 2}CO{sub 3}. The thermal cycle has been determined from TDA. Tg values of glass range from 626 degree centigrade to 709 degree centigrade. Leaching tests of the obtained glasses confirm their capacity to retain heavy metals. (Author) 38 refs.

    Full Text Available This article considers ‘kirchnerism’ and ‘evism’ to be popular identity movements which have attempted to provide answers to the open social dislocations since the crisis of December 2001 in Argentina, and the cycle of protests from 2000-2005 in Bolivia. The emergence of both of these identity constructions has involved at least three simultaneous processes. Firstly, the gradual incorporation of public decision-making on subjects and demands which were formerly ignored; secondly, political divisions within communities; and, finally, establishing a nation within the new institutional framework currently in force. As these processes developed, some points of approach and distancing between the case studies were noted.

    In 2003 a pilot study was carried out in the rural area of the Bolivian Department of La Paz aiming at the identification of dietary patterns among a group of secondary school adolescents who have little or scarce contact with the urban centres. The study consisted of a food intake survey (24 h recall), the measurement of anthropometrics and sociodemographic information. Nine percent was the global prevalence of overweight, although it was more present in girls. No statistically significant differences were found between nutrients in the diets of boys and girls. The energy intake was distributed in the five usual eating times as follows: 22% breakfast, 20% break time at school, 24% lunch, 12% tea time and 22% dinner. Furthermore, the anthropometric measures of boys were compared with their urban counterparts, where the differences were only significant with students in private schools. The present study can be used for the formulation of nutritional policies in Bolivia.

    Full Text Available From 2008 onwards, the economic crisis experienced by countries such as Spain marked a turning point in migratory flows. As a result, faced with the serious reality of unemployment and the precariousness of the Spanish labour market, the option of return has become the last resort for some immigrants, and an attractive strategy for governments (of both countries of origin and destination, which attempt to manage return using special programmes. From this point of view, the aim of this paper is to examine the assisted voluntary return programmes in Spain and Bolivia and their suitability to the dynamics of return, beginning with an exhaustive review of the programmes and the perceptions on them expressed by Bolivian immigrants as part of the survey «Circulation and Return», carried out within the framework of the RETTRANS project.

    Geodetic measurements of surface deformation are critical in volcano and earthquake studies to place constraints on associated deformation sources, to understand the interaction between volcanic processes and tectonics surroundings, and to detect and investigate emplacement of magmas prior to eruptions. In this paper, we use Envisat data from 2003 to 2009 and apply an InSAR time-series technique to study ongoing deformation at Uturuncu volcano in SW Bolivia. Following this observation, we employ analytical models to infer information about the source of deformation at depth; perform detailed GIS analysis and numerical stress models to analyze the geology surroundings and compare the results. We also model, using Envisat data acquired in Wide Swath and Image Mode, the deformation associated with the 14 November 2007 Tocopilla earthquake that occurred approx. 300 km west of Uturuncu and investigate whether the stress change caused by the fault slip during this subduction event triggered a response in the movement of source beneath Uturuncu Volcano.

  13. The Ignimbritic tertiary volcanism of the Andes (Peru, Bolivia, Argentina): its characteristics and uraniferous potentiality

    International Nuclear Information System (INIS)

    The petrographic and geochemical characteristics of the volcanism and the primary U distribution at the magmatic stage: alkali-rich volcanic rocks (Peru) appear to be fertile source-rocks, whereas sub alkaline and calc-alkaline rocks (Bolivia and Argentina) are less favorable. Uranium can only be leached from the matrix, due to the stability of the accessory minerals during all the following events. The fertility of a volcanic rock is thus directly controlled by the volume proportion of the matrix and the U fractionation between glass and accessory minerals. The preconcentration and concentration stages: the existence of mineralizations in relation with a fertile rock will depend on other events which must occur successively at the same place: the cooling type and rate of the volcanic pile (pre-concentration stage), the intensity and the duration of the hydrothermal circulations, the presence of reducing agents and trapps.

    Directory of Open Access Journals (Sweden)

    2013-03-01

    Full Text Available Upon his presidential election, Bolivian coca grower leader Evo Morales adopted a policy of promoting consensual coca reduction through social control, a sophisticated coca monitoring system, and economic development. That strategy is paying off. In 2011, coca cultivation decreased by 13 per cent according to the U.S. government. The Morales administration has also made significant progress facing the ongoing challenges of drug production and trafficking. Seizures of coca paste and cocaine and destruction of drug laboratories have steadily increased since President Morales took office. Despite continued tensions in bilateral relations, U.S.-Bolivian counter-drug cooperation continues and the signing of a new framework agreement in 2011 should lead to an exchange of ambassadors. Internationally, Bolivia has successfully gained acceptance of the right to the traditional use of coca within its own territory. But Bolivia’s efforts must be carried out in tandem with effective demand reduction strategies to shrink the global cocaine market.

    The Earth Resources Technology Satellite program of Bolivia has developed a multidisciplinary project to carry out investigations in cartography and to prepare various thematic maps. In cartography, investigations are being carried out with the ERTS-1 images and with existing maps, to determine their application to the preparation of new cartographic products on one hand and on the other to map those regions where the cartography is still deficient. The application of the MSS images to the geological mapping has given more than satisfactory results. Working with conventional photointerpretation, it has been possible to prepare regional geological maps, tectonic maps, studies relative to mining, geomorphological maps, studies relative to petroleum exploration, volcanological maps and maps of hydrologic basins. In agriculture, the ERTS images are used to study land classification and forest and soils mapping.

    Accurately defining disease distributions and calculating disease risk is an important step in the control and prevention of diseases. Geographical information systems (GIS) and remote sensing technologies, with maximum entropy (Maxent) ecological niche modelling computer software, were used to create predictive risk maps for Chagas disease in Bolivia. Prevalence rates were calculated from 2007 to 2009 household infection survey data for Bolivia, while environmental data were compiled from the Worldclim database and MODIS satellite imagery. Socio-economic data were obtained from the Bolivian National Institute of Statistics. Disease models identified altitudes at 500-3,500 m above the mean sea level (MSL), low annual precipitation (45-250 mm), and higher diurnal range of temperature (10-19 °C; peak 16 °C) as compatible with the biological requirements of the insect vectors. Socio-economic analyses demonstrated the importance of improved housing materials and water source. Home adobe wall materials and having to fetch drinking water from rivers or wells without pump were found to be highly related to distribution of the disease by the receiver operator characteristic (ROC) area under the curve (AUC) (0.69 AUC, 0.67 AUC and 0.62 AUC, respectively), while areas with hardwood floors demonstrated a direct negative relationship (-0.71 AUC). This study demonstrates that Maxent modelling can be used in disease prevalence and incidence studies to provide governmental agencies with an easily learned, understandable method to define areas as either high, moderate or low risk for the disease. This information may be used in resource planning, targeting and implementation. However, access to high-resolution, sub-municipality socio-economic data (e.g. census tracts) would facilitate elucidation of the relative influence of poverty-related factors on regional disease dynamics.

    In Bolivia Sn mining activity produces large tailings of SiO2-rich residues. These tailings contain potentially toxic elements that can be removed into the surface water and produce a high environmental pollution. This study determines the thermal behaviour and the viability of the manufacture of glass-ceramics from glass. The glass has been obtained from raw materials representative of the Sn mining activities from Llallagua (Bolivia). Temperatures of maximum nucleation rate (Tn) and crystallization (Tcr) were calculated from the differential thermal analyses. The final mineral phases were determined by X-ray diffraction and textures were observed by scanning electron microscopy. Crystalline phases are nefeline occurring with wollastonite or plagioclase. Tn for nepheline is between 680 ºC and 700 ºC, for wollastonite, 730 ºC and for plagioclase, 740 ºC. Tcr for nefeline is between 837 and 965 ºC; for wollastonite, 807 ºC and for plagioclase, 977 ºC. In order to establish the mechanical characteristics and efficiency of the vitrification process in the fixation of potentially toxic elements the resistance to leaching and micro-hardness were determined. The obtained contents of the elements leached from the glass ceramic are well below the limits established by the European legislation. So, these analyses confirm that potentially toxic elements remain fixed in the structure of mineral phases formed in the glass-ceramic process. Regarding the values of micro-hardness results show that they are above those of a commercial glass. The manufacture of glass-ceramics from mining waste reduces the volume of tailings produced for the mining industry and, in turn enhances the waste, transforming it into a product with industrial application.

  1. Microsatellites reveal a high population structure in Triatoma infestans from Chuquisaca, Bolivia.

    Directory of Open Access Journals (Sweden)

    Juan Carlos Pizarro

    Full Text Available BACKGROUND: For Chagas disease, the most serious infectious disease in the Americas, effective disease control depends on elimination of vectors through spraying with insecticides. Molecular genetic research can help vector control programs by identifying and characterizing vector populations and then developing effective intervention strategies. METHODS AND FINDINGS: The population genetic structure of Triatoma infestans (Hemiptera: Reduviidae, the main vector of Chagas disease in Bolivia, was investigated using a hierarchical sampling strategy. A total of 230 adults and nymphs from 23 localities throughout the department of Chuquisaca in Southern Bolivia were analyzed at ten microsatellite loci. Population structure, estimated using analysis of molecular variance (AMOVA to estimate F(ST (infinite alleles model and R(ST (stepwise mutation model, was significant between western and eastern regions within Chuquisaca and between insects collected in domestic and peri-domestic habitats. Genetic differentiation at three different hierarchical geographic levels was significant, even in the case of adjacent households within a single locality (R(ST = 0.14, F(ST = 0.07. On the largest geographic scale, among five communities up to 100 km apart, R(ST = 0.12 and F(ST = 0.06. Cluster analysis combined with assignment tests identified five clusters within the five communities. CONCLUSIONS: Some houses are colonized by insects from several genetic clusters after spraying, whereas other households are colonized predominately by insects from a single cluster. Significant population structure, measured by both R(ST and F(ST, supports the hypothesis of poor dispersal ability and/or reduced migration of T. infestans. The high degree of genetic structure at small geographic scales, inferences from cluster analysis and assignment tests, and demographic data suggest reinfesting vectors are coming from nearby and from recrudescence (hatching of eggs that were laid

    Full Text Available Abstract Background Molecular epidemiological studies of HIV-1 in South America have revealed the occurrence of subtypes B, F1 and BF1 recombinants. Even so, little information concerning the HIV-1 molecular epidemiology in Bolivia is available. In this study we performed phylogenetic analyses from samples collected in Bolivia at two different points in time over a 10 year span. We analyzed these samples to estimate the trends in the HIV subtype and recombinant forms over time. Materials and methods Fifty one HIV-1 positive samples were collected in Bolivia over two distinct periods (1996 and 2005. These samples were genetically characterized based on partial pol protease/reverse transcriptase (pr/rt and env regions. Alignment and neighbor-joining (NJ phylogenetic analyses were established from partial env (n = 37 and all pol sequences using Mega 4. The remaining 14 env sequences from 1996 were previously characterized based on HMA-env (Heteroduplex mobility assay. The Simplot v.3.5.1 program was used to verify intragenic recombination, and SplitsTree 4.0 was employed to confirm the phylogenetic relationship of the BF1 recombinant samples. Results Phylogenetic analysis of both env and pol regions confirmed the predominance of "pure" subtype B (72.5% samples circulating in Bolivia and revealed a high prevalence of BF1 genotypes (27.5%. Eleven out of 14 BF1 recombinants displayed a mosaic structure identical or similar to that described for the CRF12_BF variant, one sample was classified as CRF17_BF, and two others were F1pol/Benv. No "pure" HIV-1 subtype F1 or B" variant of subtype B was detected in the present study. Of note, samples characterized as CRF12_BF-related were depicted only in 2005. Conclusion HIV-1 genetic diversity in Bolivia is mostly driven by subtype B followed by BF1 recombinant strains from the CRF12_BF "family". No significant temporal changes were detected between the mid-1990s and the mid-2000s for subtype B (76.2% vs 70

    The Bolivia-Brazil Natural Gas Pipeline starts at Santa Cruz de La Sierra city, in Bolivia, and goes until Canoas City (RS) in Brazil, with a total extent of 3,150 km. The pipeline crosses in the 2,593 km established in Brazilian soil, the most diverse types of geology and geomorphology. Along the line, the right-of-way (ROW) also crosses a lot of roads, railways, rivers and lakes. During a routine inspection (foot patrol), signs of instability were detected at an embankment slope of a highway of the Santa Catarina state, at the pipeline crossing. An eventual failure of this slope could put the pipeline at risk. The aim of this paper is to present the aspects of the stabilizations phases, since field investigation, design, works, instrumentation, until monitoring. Emphasis is given to the design criteria to pipeline safety. The solution adopted is composite by soil nailing, a changing of slope inclination and superficial drainage system. (author)

    Full Text Available Bolivia is a high-endemic country for Chagas disease, for which the principal vector is Triatoma infestans (Triatominae. This is a mainly domestic species that is also found in the wild environment. Recently, an increasing number of studies have shown the importance of Triatominae resistance to insecticides, especially in Bolivia. Data regarding the susceptibility/resistance of wild and domestic populations of T. infestans to deltamethrin are presented. For the first time, domestic populations of the department of Santa Cruz were tested, showing low resistance. Although most of the wild populations were found to be susceptible to deltamethrin, three populations from three departments showed a mortality rate of less than 100%. This result is emphasised here.

    Full Text Available El 18 de julio del 2004 se dio el primer referéndum sobre los hidrocarburos en Bolivia; el proceso pre-referéndum puso en manifiesto problemas nacionales que amenazaban la estabilidad social. Este trabajo analiza las posiciones de los sectores sociales organizados y de los partidos políticos más importantes de Bolivia, en una coyuntura política conflictiva donde las diferencias entre los distintos actores sociales y políticos imposibilitaban el establecimiento de una política hidrocarburífera consensuada desde el Ejecutivo. Del mismo modo estudia cómo estos hechos influyeron en las características de la iniciativa presidencial en la política de hidrocarburos. Finalmente, muestra que en su momento el referéndum sirvió para legitimar al Presidente Carlos Mesa, pero a la larga las discrepancias entre el poder legislativo y el poder ejecutivo en torno a la interpretación de los resultados del referéndum contribuyeron al debilitamiento del Presidente y a su posterior renuncia.The referendum of July 2004 in Bolivia over hydrocarbon policies in Bolivia disclosed many of the national problems that threatened social peace. This paper analyses the attitudes of different labor unions, political parties, and civic communities within the context of the referendum and how the stances of political and social actors in the referendum produced internal divisions. It also examines how these groups' different points of view on President Mesa's hydrocarbon policy contributed to the call for a referendum. The work demonstrates that for a short period of time the referendum served to legitimize Carlos Mesa's presidency but in a long run defeated of it own presidency.

    Chilean red chili peppers contaminated with aflatoxins were reported in a previous study. If the development of gallbladder cancer (GBC) in Chile is associated with a high level of consumption of aflatoxin-contaminated red chili peppers, such peppers from other countries having a high GBC incidence rate may also be contaminated with aflatoxins. We aimed to determine whether this might be the case for red chili peppers from Bolivia and Peru. A total of 7 samples (3 from Bolivia, 4 from Peru) and 3 controls (2 from China, 1 from Japan) were evaluated. Aflatoxins were extracted with acetonitrile:water (9:1, v/v) and eluted through an immuno-affinity column. The concentrations of aflatoxins B1, B2, G1, and G2 were measured using high-performance liquid chromatography (HPLC), and then the detected aflatoxins were identified using HPLC-mass spectrometry. In some but not all of the samples from Bolivia and Peru, aflatoxin B1 or aflatoxins B1 and B2 were detected. In particular, aflatoxin B1 or total aflatoxin concentrations in a Bolivian samples were above the maximum levels for aflatoxins in spices proposed by the European Commission. Red chili peppers from Bolivia and Peru consumed by populations having high GBC incidence rates would appear to be contaminated with aflatoxins. These data suggest the possibility that a high level of consumption of aflatoxin-contaminated red chili peppers is related to the development of GBC, and the association between the two should be confirmed by a case-control study.

    Full Text Available Here we report a superbly preserved and profusely represented five-ichnotaxa dinosaur track assemblage near Icla village, 100 km southeast of Sucre, Bolivia. As preserved in reddish Jurassic-Cretaceous boundary aeolian sandstones, this rich and uncommon assemblage is, additionally, the oldest dinosaur tracksite for Bolivia. Four trackmakers were identified in the area: three quadrupedal and one bipedal, all of them with tracks of around 35 cm in lenght. One of the quadrupedals is represented by no less than five adult individuals (ichnotaxon A, and four purported juveniles (ichnotaxon B walking in association. The other two quadrupedals (ichnotaxa C and D involve four trackways, and the last, the bipedal trackmaker (ichnotaxon E, is represented by one trackway. The five ichnotaxa represented in the "Palmar de Tunasniyoj" could be tentatively assigned to the following trackmakers: Ichnotaxa A and B are assigned to basal stegosaurians; ichnotaxon C to a basal tyreophoran, perhaps related to the ankylosaur lineage; ichnotaxon D to the Ankylosauria, and ichnotaxon E to Theropoda. The Tunasniyoj assemblage, the oldest dinosaur tracksite for Bolivia, includes the oldest known evidence assigned to ankylosaurs and stegosaurs for South America.Neste estudo é relatado um conjunto magnificamente preservado de pistas de dinossauros representados por cinco táxons distintos, situado próximo à Vila de Icla, 100 quilômetros a sudeste do Sucre, Bolívia.

    The northern Altiplano plateau of southern Peru and northern Bolivia is one of the highest topographic features on the Earth, flanked by Western and Eastern Cordillera along its margin. It has strongly influenced the local and far field lithospheric deformation since the early Miocene (Masek et al., 1994). Previous studies have emphasized the importance of both the crust and upper mantle in the evolution of Altiplano plateau (McQuarrie et al., 2005). Early tomographic and receiver function studies, south of 16° S, show significant variations in the crust and upper mantle properties in both perpendicular and along strike direction of the Altiplano plateau (Dorbath et. al., 1993; Myers et al., 1998; Beck and Zandt, 2002). In order to investigate the nature of subsurface lithospheric structure below the northern Altiplano, between 15-18° S, we have determined three-dimensional seismic tomography models for Vp and Vs using P and S-wave travel time data from two recently deployed local seismic networks of CAUGHT and PULSE. We also used data from 8 stations from the PERUSE network (PERU Subduction Experiment). Our preliminary tomographic models show a complex variation in the upper mantle velocity structure with depth, northwest and southeast of lake Titicaca. We see the following trend, at ~85 km depth, northwest of lake Titicaca: low Vp and Vs beneath the Western Cordillera, high Vs beneath the Altiplano and low Vp and Vs beneath the Eastern Cordillera. This low velocity anomaly, beneath Eastern Cordillera, seems to coincide with Kimsachata, a Holocene volcano in southern Peru. At depth greater than ~85 km: we find high velocity anomaly beneath the Western Cordillera and low Vs beneath the Altiplano. This high velocity anomaly, beneath Western Cordillera, coincides with the well-located Wadati-Benioff zone seismicity and perhaps represents the subducting Nazca slab. On the southeast of lake Titicaca, in northern Bolivia, we see a consistently high velocity anomaly

    Recent insights shed light on the global mechanisms involved in the abrupt oscillations of the Earth climate for the Late Glacial Maximum (LGM) to Holocene period (Zhang et al., 2014; Banderas et al., 2015). Yet the concomitant patterns of regional climate reorganization on continental areas are for now poorly documented. Particularly, few attempts have been made to propose temporal reconstructions of the regional climate variables in the High Tropical Andes, a region under the direct influence of the upper part of the troposphere. We present new glacial chronologies from the Zongo (16.3°S - 68.1°W, Bolivia) and Wara-Wara (17.3°S - 66.1°W, Bolivia) valleys based on Cosmic Ray Exposure dating (CRE) from an exceptional suite of recessive moraines. These new data permitted to refine existing chronologies (Smith et al., 2005 ; Zech et al., 2010): the Zongo valley is characterized by an older local last glacial maximum than the Wara Wara valley. Both sites however exhibit similar glacier behaviours, with a progressive regression between 18 ka and the Holocene. In both sites, glaciers recorded stillstand episodes synchronous with the cold events of the Norther Hemisphere (Henrich 1 event, Younger Dryas). Since the nearby Altiplano basin registered lake level variations over the same period, we were able to apply a joint modelling of glaciers Equilibrium Line Altitude (ELA) and lake budget. This permits to derive a temporal evolution of temperature and precipitation for both sites. These new reconstructions show for both sites that glaciers of the Eastern Tropical Andes were both influenced by the major climatic events of the Northern and Southern Hemispheres. However, precipitation variability is more influenced by the Northern Atlantic events. This observation is in good agreement with the theories suggesting that North Hemisphere cold events are coeval with an important southward deflexion of the Intertropical Convergence Zone (ITCZ) due to the inter

    This case study analyses current migration dynamics in two regions of Bolivia: Northern Potosi, one of the main areas of outmigration in Bolivia, and the municipality of San Julian in the Department of Santa Cruz, a major destination for internal migrants, some of whom come from Northern Potosi. The research was qualitative in nature, with specific attention to breadth and accuracy in the information and analysis. The methods used were participative and the research was done in collaboration with the rural and indigenous organisations in the two selected areas: the Federation of Indigenous Ayllus of Northern Potosi (Federacion de Ayllus Originarios Indigenas del Norte de Potosi Charka Qhara Qhara - FAOI-NP) and the Federation of Intercultural Communities of San Julian (Federacion de Comunidades Interculturales de San Julian). The information gathering process examined a wide range of factors that may trigger migration, including the possible influence of climate change and public policies on migration. The key challenge was to understand current patterns of migration, the processes involved and the social, cultural, economic and political causes and effects, taking into account issues that are increasing in importance, such as climate change, and seeking to discover the extent of their influence in the midst of other factors that drive migration. It is well known that migration is not a simple occurrence. In fact, it involves a series of processes, motivations, causes and decisions. Because it is a collective rather than an individual process, it takes on the character of a 'social phenomenon' that is historically and geographically determined. In many cases, there are cultural practices of transhumance, such as agriculture on different ecological levels or the use of winter and summer pastures. This involves people moving from one place to another, sometimes travelling long distances and crossing districts for several months at a time. These transhumance

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

    Full Text Available RESUMEN: El artículo —que comenta el Informe Desarrollo Humano de Bolivia 2000— se pregunta ¿qué significa globalizarse para un país? ¿Es posible medirla desde las dimensiones subjetivas de la interacción social? ¿Cuáles son los límites de la modificación de la "personalidad social" de las naciones? Para proyectarse en el mundo globalizado es necesario interactuar desde la definición de los intereses "propios". Hay que definir los cambios en los paradigmas de la subjetividad para asumir la comparación y examinar las aptitudes para conservar y modificar a la nación. En suma, ¿Estamos construyendo formas específicas de ser en la globalización? La forma de entendernos en los "poderes" de la globalización es disponer de un arsenal mínimo de "saberes". Es una medición de la autonomía para relacionarse. Permite "negociar" la inserción en la globalización, que plantea las formas de una construcción conjunta y conflictiva de los sentidos de la historicidad (compromisos. Acerca de las tareas pendientes, en el ámbito político, el artículo sostiene que deben fortalecerse las instituciones: cuando la sociedad asedia con su dinámica contradictoria, las instituciones no pueden construir su lógica valórica. En el ámbito económico, debe re-enrumbarse el sentido de la competitividad: ¿Se puede conducir la eficiencia hacia la solidaridad? En el ámbito social, debe superarse la extrema pobreza: existe una enorme incapacidad para producir un pacto nacional contra la pobreza ya que los pactos políticos no tienen pactos sociales de sustento.La educación aparece como la posibilidad de (re conocer a la inserción internacional como una oportunidad.

    The chronology, sedimentary history, and paleoecology of the Tarija Basin (Bolivia), one of the richest Pleistocene mammalian sites in South America, are revised here based on a multidisciplinary study, including stratigraphy, sedimentology, geomorphology, paleontology, isotope geochemistry, and (14)C geochronology. Previous studies have indicated a Middle Pleistocene age for this classic locality. We have been able to obtain a series of (14)C dates encompassing all the fossil-bearing sequences previously studied in the Tarija Basin. The dated layers range in age from about 44,000 to 21,000 radiocarbon years before present (BP), indicating that the Tarija fauna is much younger than previously thought. Glacial advances correlated to marine isotopic stages (MIS) 4 and 2 (ca. 62 and 20 ka BP, respectively) are also documented at the base and at the very top of the Tarija-Padcaya succession, respectively, indicating that the Bolivian Altiplano was not dry but sustained an ice cap during the Last Glacial Maximum. The results of this multidisciplinary study enable us to redefine the chronological limits of the Tarija sequence and of its faunal assemblage and to shift this paleontological, paleoclimatological, and paleoecological framework to the time interval from MIS 4 to MIS 2.

El boom de la quinua, la expansión de la frontera agrícola y la suspensión de la construcción de una carretera que atraviese el TIPNIS son algunos de los temas que se discuten. Internacionalmente, hay motivos de optimismo con relación a la demanda marítima de Bolivia, mientras que, a nivel nacional, el MAS aseguró una victoria parlamentaria en el año 2014. Las reformas menos exitosas son las del órgano judicial. La presentación termina revisando los movimientos sociales que permitieron la formación la de Asamblea Constituyente y el asunto de la autonomía municipal, departamental e indígena.

    In the Andes, as elsewhere, infanticide is a difficult challenge that remains largely undocumented and misunderstood. From January to March 2004 we used community-based vital event surveillance systems, discussions with health staff, ethnographic interviews, and focus group discussions among Aymara men and women from two geographically distinct sites in the Andes of Bolivia to provide insights into the practice of infanticide. We noted elevated mortality at both sites. In one location, suspected causes of infanticide were especially high for girls. We also observed that community members maintain beliefs that justify infanticide under certain circumstances. Among the Aymara, justification for infanticide was both biological (deformities and twinship) and social (illegitimate birth, family size and poverty). Communities generally did not condemn killing when reasons for doing so were biological, but the taking of life for social reasons was rarely justified. In this cultural context, strategies to address the challenge of infanticide should include education of community members about alternatives to infanticide. At a program level, planners and implementers should target ethnic groups with high levels of infanticide and train health care workers to detect and address multiple warning signs for infanticide (for example, domestic violence and child maltreatment) as well as proxies for infant neglect and abuse such as mother/infant separation and bottle use.

    Since 2005, great progress has been made in health care provision to patients with terminal renal failure in Bolivia. Access to dialysis and transplantation is regulated by the Ministry of Health, based on clinical criteria, applied equitably, without favoritism or discrimination based on race, sex, economic means, or political power. Until December 2013, there were no restrictions in dialysis and transplantation in Health Insurance institutions, but they covered only 30% of the population. Now the remaining 70% has access to free dialysis funded by the communities where patients live, with funds coming from the government and taxes on oil products. More than 2,231 people are getting dialysis, reaching a population growth of >60% annually. The number of hemodialysis units has increased by >200% (60 units), making access easier for end-stage renal failure patients. Treatment protocols have been drawn up to guarantee the best quality of life for the patients. The Law on Donation and Transplantation was enacted in 1996, and Supplementary Regulations were enacted in 1997 with various amendments over the past 5 years. A National Transplant Coordination Board, working under the National Renal Health Program, supervises and regulates transplants and promotes deceased-donor transplantation in an attempt to cover the demand for donors. Rules have been drawn up for accreditation of transplant centers and teams to guarantee the best possible conditions and maximum guaranties. Since January 2014, the National Renal Health Program has been providing free kidney transplants from living donors. PMID:27110002

    This study examined the association between food insecurity, determined by a modified version of the U.S. Household Food Security Survey Module (US HFSSM), and total daily per capita (DPC) consumption (measured as household expenditures) in Bolivia, Burkina Faso, and the Philippines. Household food insecurity was determined by an adapted 9-item US HFSSM version. A short version of the World Bank's Living Standards Measurement Study (LSMS) consumption module measured household expenditures. Focus groups were used to adapt the survey instrument to each local context. The sample (n approximately 330 per country) includes residents of urban and rural areas. A 12-month food expenditure aggregate was generated as part of the total household expenditures calculation. DPC food expenditure, which represented over 60% of the total household consumption, as well as expenditures on specific food groups correlated with food insecurity both as a continuous Food Insecurity Score (FinSS) and a tricategorical food insecurity status variable. ANOVA and regression analysis were executed adjusting for social and demographic covariates. Food-secure households have significantly higher (P expenditures as well as expenditures on animal source foods, vegetables, and fats and oils than moderately and severely food-insecure households. The results offer evidence that the US HFSSM is able to discriminate between households at different levels of food insecurity status in diverse developing world settings.

  9. A new snake skull from the Paleocene of Bolivia sheds light on the evolution of macrostomatans.

    Full Text Available Macrostomatan snakes, one of the most diverse extant clades of squamates, display an impressive arsenal of cranial features to consume a vast array of preys. In the absence of indisputable fossil representatives of this clade with well-preserved skulls, the mode and timing of these extraordinary morphological novelties remain obscure. Here, we report the discovery of Kataria anisodonta n. gen. n. sp., a macrostomatan snake recovered in the Early Palaeocene locality of Tiupampa, Bolivia. The holotype consists of a partial, minute skull that exhibits a combination of booid and caenophidian characters, being the presence of an anisodont dentition and diastema in the maxilla the most distinctive trait. Phylogenetic analysis places Kataria basal to the Caenophidia+Tropidophiidae, and represents along with bolyeriids a distinctive clade of derived macrostomatans. The discovery of Kataria highlights the morphological diversity in the maxilla among derived macrostomatans, demonstrating the relevance of maxillary transformations in the evolution of this clade. Kataria represents the oldest macrostomatan skull recovered, revealing that the diversification of macrostomatans was well under way in early Tertiary times. This record also reinforces the importance of Gondwanan territories in the history of snakes, not only in the origin of the entire group but also in the evolution of ingroup clades.

  10. Full moment tensors for small events (Mw<3) at Uturuncu volcano, Bolivia

    2016-07-01

    We present a catalog of full seismic moment tensors for 63 events from Uturuncu volcano in Bolivia. The events were recorded during 2011-2012 in the PLUTONS seismic array of 24 broadband stations. Most events had magnitudes between 0.5 and 2.0 and did not generate discernible surface waves; the largest event was Mw 2.8. For each event we computed the misfit between observed and synthetic waveforms, and we used first-motion polarity measurements to reduce the number of possible solutions. Each moment tensor solution was obtained using a grid search over the six-dimensional space of moment tensors. For each event we show the misfit function in eigenvalue space, represented by a lune. We identify three subsets of the catalog: (1) 6 isotropic events, (2) 5 tensional crack events, and (3) a swarm of 14 events southeast of the volcanic center that appear to be double couples. The occurrence of positively isotropic events is consistent with other published results from volcanic and geothermal regions. Several of these previous results, as well as our results, cannot be interpreted within the context of either an oblique opening crack or a crack-plus-double-couple model. Proper characterization of uncertainties for full moment tensors is critical for distinguishing among physical models of source processes.

  11. Aerosol composition at Chacaltaya, Bolivia, as determined by size-fractionated sampling

    Adams, F.; van Espen, P.; Maenhaut, W.

    Thirty-four cascade-impactor samples were collected between September 1977 and November 1978 at Chacaltaya, Bolivia. The concentrations of 25 elements were measured for the six impaction stages of each sample by means of energy-dispersive X-ray fluorescence and proton-induced X-ray emission analysis. The results indicated that most elements are predominantly associated with a unimodal coarse-particle soil-dustdispersion component. Also chlorine and the alkali and alkaline earth elements belong to this group. The anomalously enriched elements (S, Br and the heavy metals Cu, Zn, Ga, As, Se, Pb and Bi) showed a bimodal size distribution. Correlation coefficient calculations and principal component analysis indicated the presence in the submicrometer aerosol mode of an important component, containing S, K, Zn, As and Br, which may originate from biomass burning. For certain enriched elements (i.e. Zn and perhaps Cu) the coarse-particle enrichments observed may be the result of the true crust-air fractionation during soil-dust dispersion.

  12. Four thousand years of environmental change and human activity in the Cochabamba Basin, Bolivia

    Williams, Joseph J.; Gosling, William D.; Coe, Angela L.; Brooks, Stephen J.; Gulliver, Pauline

    The Cochabamba Basin (Bolivia) is on the ancient road network connecting Andean and lowland areas. Little is known about the longevity of this trade route or how people responded to past environmental changes. The eastern end of the Cochabamba valley system constricts at the Vacas Lake District, constraining the road network and providing an ideal location in which to examine past human-environmental interactions. Multi-proxy analysis of sediment from Lake Challacaba has allowed a c. 4000 year environmental history to be reconstructed. Fluctuations in drought tolerant pollen taxa and calcium carbonate indicate two periods of reduced moisture availability ( c. 4000-3370 and c. 2190-1020 cal yr BP) compared to adjacent wetter episodes ( c. 3370-2190 and c. 1020 cal yr BP-present). The moisture fluctuations broadly correlate to El Niño/Southern Oscillation variations reported elsewhere. High charcoal abundance from c. 4000 to 2000 yr ago indicates continuous use of the ancient road network. A decline in charcoal and an increase in dung fungus ( Sporormiella) c. 1340 -1210 cal yr BP, suggests that cultural changes were a major factor in shaping the modern landscape. Despite undisputable impacts of human populations on the Polylepis woodlands today, we see no evidence of woodland clearance in the Challacaba record.

    New diseases known locally as 'hoja de perejil' of tomato (Lycopersicon esculentum Mill) and 'brotes grandes' of potato (Solanum tuberosum L.) were first recognized in surveys of production fields in Bolivia during 2000-2003. Alfalfa (Medicago sativa) witches' broom and little leaf diseases of native weeds Morrenia variegata and mora-mora (Serjania perulacea) were also identified near to production fields. Phytoplasma aetiology was attributed to each of these diseases following detection and initial identification of aster yellows group (16SrI) phytoplasmas in all five diseased plant species. While potato, alfalfa and mora-mora plants contained indistinguishable 16SrI-B strains, 'hoja de perejil' (THP) and morrenia little leaf (MVLL)-associated phytoplasma strains shared 97.5 % 16S rRNA gene sequence similarity with 'Candidatus Phytoplasma asteris' and related strains and <95 % similarity with all other 'Candidatus Phytoplasma' species. Phylogenetic analysis of 16S rRNA gene sequences indicated that the THP and MVLL phytoplasmas represent a novel lineage within the aster yellows (16SrI) group and, on the basis of unique 16S rRNA gene sequences, we propose that THP and MVLL phytoplasmas represent 'Candidatus Phytoplasma lycopersici', with THP as the reference strain.

    In the Bolivian Altiplano, a number of environmental variables combine to produce some of the most exotic and poorly understood lacustrine environments on Earth. In a cold, arid environment with extreme ultraviolet flux, these lakes provide a habitat for biology and a proxy for the study of potentially analogous martian environments. Here, we present new data on the physical, chemical environment of three such lakes at Licancabur Volcano, Bolivia and explore the quantitative basis for an analogy to Mars. Licancabur (22°50`'S, 67°53`'W) is a large, dormant volcano on the western edge of the Bolivian Altiplano at the border with Chile. Two hypersaline lakes, Laguna Blanca and Laguna Verde, are located at the volcano`'s 4300 m base. Within the past thirty years, these two were connected as a single reservoir, but local climate-driven evaporation (precipitation 1000 mm/y) has resulted in two topographically and chemically distinct bodies connected by a small stream. At nearly 6000 m, the small crater lake of Licancabur is one of the highest known and least explored on Earth. While sub-freezing average air temperature and extreme ultraviolet flux create an environment similar to the surface of Mars, the lake harbors a small biological community and is ice-covered only part of the year.

  15. Bolivia: hundimiento de la Asamblea Constituyente y naufragio del proyecto de Constitución

    Full Text Available Bolivia cierra una coyuntura en el cual la Asamblea Constituyente no sirvió sino para acentuar los problemas estructurales de la sociedad. Un nuevo proyecto de Constitución, cuya filosofía reivindica el carácter multiétnico de la sociedad y la aspiración colectiva de justicia social, no ha podido lograr la forma de un pacto social nacional ni una formulación sencilla favorable a la construcción de un nuevo Estado. Los cambios anunciados están trabados por el centralismo que el MAS ejerce en la toma de decisiones, por la ineficacia táctica de sus operadores políticos y por la dependencia de su política internacional. A pesar de un escenario interior conflictivo, la crisis boliviana podría atemperarse gracias a la influencia de los factores externos regionales: Brasil, potencia emergente, secundado por Argentina y Chile aspiran consolidar una zona libre de conflictos en el Cono Sur.

  16. The sensitivity of wet and dry tropical forests to climate change in Bolivia

    Bolivia's forests contribute to the global carbon and water cycle, as well as to global biodiversity. The survival of these forests may be at risk due to climate change. To explore the associated mechanisms and uncertainties, a regionally adapted dynamic vegetation model was implemented for the Bolivian case, and forced with two contrasting climate change projections. Changes in carbon stocks and fluxes were evaluated, factoring out the individual contributions of atmospheric carbon dioxide ([CO2]), temperature, and precipitation. Impacts ranged from a strong increase to a severe loss of vegetation carbon (cv), depending on differences in climate projections, as well as the physiological response to rising [CO2]. The loss of cv simulated for an extremely dry projection was primarily driven by a reduction in gross primary productivity, and secondarily by enhanced emissions from fires and autotrophic respiration. In the wet forest, less precipitation and higher temperatures equally reduced cv, while in the dry forest, the impact of precipitation was dominating. The temperature-related reduction of cv was mainly due to a decrease in photosynthesis and only to lesser extent because of more autotrophic respiration and less stomatal conductance as a response to an increasing atmospheric evaporative demand. Under an extremely dry projection, tropical dry forests were simulated to virtually disappear, regardless of the potential fertilizing effect of rising [CO2]. This suggests a higher risk for forest loss along the drier southern fringe of the Amazon if annual precipitation will decrease substantially.

  17. Small scale mining cooperatives in Bolivia: From lifeguard of the poor to machinery of political manipulation

    2013-11-01

    Full Text Available This article argues that relations between social movements and organizations and the State are not only developed based on defended objectives and interests in political negotiations, but are also developed within particular situations, of specific cultures and histories. Our investigation about the relationship between mining cooperatives, their national organization, and the Bolivian State demonstrates the crucial importance of considering historical aspects, of collective memory, some regional and others within the organizations themselves. The traditions, memories, and abilities incorporated in the mining organizations and in the political realm will influence the way in which different parts relate to one another, design their strategies, and adapt to changing circumstances. This topic is illustrated firstly through a historical and contemporary account of mining in Bolivia focused in the sector of small scale mining. This is followed by outlining the position that cooperative mining occupies in the country and the strategies and self esteem that they display. Next, our case study is addressed: the ASOBAL cooperative. In the national outline, like in our case study, we connect the positions and strategieswith themes of identity, memory, and place.

  18. The expansion of brown rot disease throughout Bolivia: possible role of climate change.

    Bacterial wilt is a devastating plant disease caused by the bacterial pathogen Ralstonia solanacearum species complex and affects different crops. Bacterial wilt infecting potato is also known as brown rot (BR) and is responsible for significant economic losses in potato production, especially in developing countries. In Bolivia, BR affects up to 75% of the potato crop in areas with high incidence and 100% of stored potatoes. The disease has disseminated since its introduction to the country in the mid-1980s mostly through contaminated seed tubers. To avoid this, local farmers multiply seed tubers in highlands because the strain infecting potatoes cannot survive near-freezing temperatures that are typical in the high mountains. Past disease surveys have shown an increase in seed tubers with latent infection in areas at altitudes lower than 3000 m a.s.l. Since global warming is increasing in the Andes Mountains, in this work, we explored the incidence of BR in areas at altitudes above 3000 m a.s.l. Results showed BR presence in the majority of these areas, suggesting a correlation between the increase in disease incidence and the increase in temperature and the number of irregular weather events resulting from climate change. However, it cannot be excluded that the increasing availability of latently infected seed tubers has boosted the spread of BR. PMID:26991236

    The polygyny-fertility hypothesis states that polygyny is associated with reduced fertility for women and is supported by a large body of literature. This finding is important, because theoretical models of polygyny often differentiate systems based on the degree to which women are forced or willingly choose to enter polygynous marriages. The fact that polygyny tends to be associated with reduced fertility has been presented as evidence that polygyny is often less favourable for women, and that women must, therefore, be pressured into accepting such arrangements. Previous studies, however, have been hampered by the non-random assignment of women into monogamous and polygynous unions (i.e. self-selection), as differences between these groups of women might explain some of the effects. Furthermore, the vast majority of such studies focus on sub-Saharan populations. We address these problems in our analysis of women's fertility in polygynous marriages among the Tsimane of Bolivia. We offer a more robust method for assessing the impact of polygynous marriage on reproductive outcomes by testing for intra-individual fertility effects among first wives as they transition from monogamous to polygynous marriage. We report a significant link between polygyny and reduced fertility when including all cases of polygyny; however, this association disappears when testing only for intra-individual effects.

  20. Transient convection over the Amazon-Bolivia region and the dynamics of drought over Northeast Brazil

    A two layer, nonlinear, equatorial beta-plane model, in p-coordinates is used to study the atmospheric response to a large scale prescribed heat source varying in time. The heat source is meant to represent a convective burst with total duration of approximately 48 hours over the Amazon/Bolivia region. The boundary conditions used are meridional velocity zero at 60 deg S, omega w = 0 at the top and zero geometric velocity at the lower boundary. Sensitivity study was done which includes initial state at rest, compared with realistic initial flow. The scale of the heat source is 1500 km in latitude and longitude and it is centered at 10 deg S. Special attention is paid to the distribution and intensity of the induced vertical motion. The model is integrated for two days and the preliminary results show agreement with the observed 200 mb flow. Of interest is the establishment of a trough and descending motion to the northeast of the heat source. A conjucture is thus made that the Amazon heat source and its fluctuations bear some relationship with the drought problem over Northeast Brazil.

    By the end of the 1960s, the argasid tick Ornithodoros peropteryx was described from larval specimens collected from the bat Peropteryx macrotis in Colombia. Since its original description, no additional record of O. peropteryx has been reported, and its post-larval stages have remained unknown. During July 2010, 18 larvae were collected from 9 bats (Centronycteris maximiliani), resulting in a mean infestation of 2.0 ± 2.2 ticks per bat (range 1-8). These bats were captured in a farm in northeastern Bolivia close to Guaporé River in the border with Brazil. Morphological examinations of the larvae revealed them to represent the species O. peropteryx. One engorged larva that was kept alive in the laboratory moulted to a nymph after 9 days. Fourteen days after the larval moulting, the nymph moulted to an adult female without taking any blood meal during the nymphal period. This adult female was used for a morphological description of the female stage of O. peropteryx. In addition, the larvae were used for a morphological redescription of this stage. One larva and two legs extirpated from the adult female were submitted to DNA extraction and PCR targeting a fragment of the mitochondrial 16S rDNA gene, which yielded DNA sequences at least 11 % divergent from any available argasid sequence in Genbank. We show that O. peropteryx ontogeny is characterized by a single, non-feeding, nymphal stage. This condition has never been reported for ticks. PMID:23543273

  2. The compatibility of agricultural intensification in a global hotspot of smallholder agrobiodiversity (Bolivia).

    Integrating the conservation of biodiversity by smallholder farmers with agricultural intensification is increasingly recognized as a leading priority of sustainability and food security amid global environmental and socioeconomic change. An international research project investigated the smallholder agrobiodiversity of maize (corn) in a global hotspot (Bolivia) undergoing significant intensification. Peach-based intensification was pronounced (300-400%) and prolonged (2000-2010) in study areas. Intensification and maize agrobiodiversity were found to co-occur within smallholder landscapes. Interactions of these field systems did not trigger land-change tipping points leading to landrace extirpation. By 2010 maize landraces in the study areas still demonstrated high levels of taxonomic and ecological biodiversity and contributed significantly to this crop's agrobiodiversity at national (31%) and hemispheric (3%) scales. Social and ecological resilience and in situ conservation of the maize agrobiodiversity by Bolivian smallholders was enabled through robust linkages to off-farm migration; resource access and asset capabilities among both traditional and nontraditional growers; landrace agroecology and food uses; and innovative knowledge and skills. The smallholders' resilience resulting from these linkages was integral to the conditional success of the in situ conservation of maize agrobiodiversity. Environment-development interactions both enabled smallholders' agrobiodiversity resilience and influenced the limits and vulnerability of agrobiodiversity. Scientific policy recommendations regarding land-use planning and sustainability analysis are targeted to specific Río+20 priorities for agrobiodiversity.

    Full Text Available BACKGROUND: The causative agent of Chagas disease, Trypanosoma cruzi, is divided into 6 Discrete Typing Units (DTU: Tc I, IIa, IIb, IIc, IId and IIe. In order to assess the relative pathogenicities of different DTUs, blood samples from three different clinical groups of chronic Chagas disease patients (indeterminate, cardiac, megacolon from Bolivia were analyzed for their circulating parasites lineages using minicircle kinetoplast DNA polymorphism. METHODS AND FINDINGS: Between 2000 and 2007, patients sent to the Centro Nacional de Enfermedades Tropicales for diagnosis of Chagas from clinics and hospitals in Santa Cruz, Bolivia, were assessed by serology, cardiology and gastro-intestinal examinations. Additionally, patients who underwent colonectomies due to Chagasic magacolon at the Hospital Universitario Japonés were also included. A total of 306 chronic Chagas patients were defined by their clinical types (81 with cardiopathy, 150 without cardiopathy, 100 with megacolon, 144 without megacolon, 164 with cardiopathy or megacolon, 73 indeterminate and 17 cases with both cardiopathy and megacolon. DNA was extracted from 10 ml of peripheral venous blood for PCR analysis. The kinetoplast minicircle DNA (kDNA was amplified from 196 out of 306 samples (64.1%, of which 104 (53.3% were Tc IId, 4 (2.0% Tc I, 7 (3.6% Tc IIb, 1 (0.5% Tc IIe, 26 (13.3% Tc I/IId, 1 (0.5% Tc I/IIb/IId, 2 (1.0% Tc IIb/d and 51 (25.9% were unidentified. Of the 133 Tc IId samples, three different kDNA hypervariable region patterns were detected; Mn (49.6%, TPK like (48.9% and Bug-like (1.5%. There was no significant association between Tc types and clinical manifestations of disease. CONCLUSIONS: None of the identified lineages or sublineages was significantly associated with any particular clinical manifestations in the chronic Chagas patients in Bolivia.

    2004-03-01

    Full Text Available Fossil plants belonging to the morphogenera Glossopteris, Pecopteris and Asterotheca were collected from the upper part of the Chutani Formation (Titicaca Group, near the town of San Pablo de Tiquina, on the southeastern shore of Lake Titicaca (northern Altiplano, Bolivia. This paper presents the first description of specimens of the morphogenus Glossopteris from Bolivia. The Bolivian specimens of Glossopteris consist of poorly-preserved impressions, although they present the diagnostic features of this morphogenus. They are fragments of leaves with secondary veins of taeniopterid-type, typical of glossopterids from Late Permian deposits of Gondwana. The only species of Pecopteris confirmed in the first part of this study, i.e. P. dolianitii Rösler and Rohn (see Vieira et al. 2004, was previously reported from the Late Permian beds of the Rio do Rasto and Estrada Nova formations in the Paraná Basin (southern Brazil. Therefore, a Late Permian age is proposed for the fossil plant-bearing beds of the Chutani Formation based on the analyzed assemblage. The phytogeographic implications of this new find are briefly analyzed.Plantas fósseis, pertencentes aos morfo-gêneros Glossopteris, Pecopteris e Asterotheca, foram coletadas na porção superior da seção aflorante da Formação Chutani, próxima ao povoado de San Pablo de Tiquina, sudeste do lago Titicaca (Altiplano norte, Bolívia. Este trabalho apresenta a primeira descrição de espécimes do morfo-gênero Glossopteris provenientes da Bolívia. Os espécimes estudados de Glossopteris consistem em impressões foliares pobremente preservadas nas quais feições diagnósticas estão presentes. Os fragmentos foliares apresentam venação secundária do tipo teniopteróide, uma característica típica de glossopterídeas encontradas em depósitos do Permiano Superior do Gondwana.

    This paper argues that migration is better defined as an adaptive response to socio-economic, cultural, political and environmental transformations, in most instances closely linked to the need to diversify income sources and reduce dependency on natural resources. Drawing on case studies in Bolivia, Senegal and Tanzania, it describes how environmental change at the local level interacts with other factors to shape migration patterns, and how such patterns in turn affect the livelihoods and resilience of individuals, households and communities in areas experiencing the impacts of climate change in the form of desertification, soil degradation, disrupted rainfall patterns and changes in temperature.

  15. Rural power supply with local management: Examples from Bolivia, India and Nepal

    Energy Technology Data Exchange (ETDEWEB)

    1997-08-01

    Local management of rural power supply is being evaluated in a joint research project conducted by Tanzania Electric Supply Company Limited (TANESCO) and Stockholm Environment Institute (SEI) on new approaches to management and organization of rural electrification. The study is based on literature, and on data from eight visited local organizations for management of power supply in Bolivia (4), India (1) and Nepal (3). Common for these countries is that the national, rural electrification programmes have encountered difficulties. Governments have failed to generate enough funds from existing power supply systems to cover the cost for a continued rural electrification. In cases where large private companies exist, they have had few incentives for expanding into rural areas since it is often not profit making. A third category may be defined as local initiators to power supply, private or co-operative. In all these countries, locally managed power supply systems have developed as a complement to governmental and other large scale programmes. The national policies pertaining to rural power supply in general and local management thereof in particular are described for each country. From the study, it appears that local management of rural power supply is a feasible approach in developing countries. Local management of rural power supply can slightly lower the costs of electrification, and it may help accelerate the pace of load development in newly electrified areas. For successful local organizations though, the most significant factor appears to be local peoples` willingness to develop their own area. Important though, is that proper financial and technical assistance is provided the local organizations. Crucial for sound external assistance is that the national rural electrification policies are clear and consistent. 53 refs, 1 fig, 11 tabs

  16. Referéndum y asamblea constituyente: autonomías departamentales en Bolivia.

    2006-12-01

    Full Text Available On 2 July 2006, Bolivia held a national referendum about departamental autonomy as part of the process of state decentralization and as an institutional response to the dire political and social crisis. The inclusion in the constitution of figures such as referendum, constitutional assembly and citizen legislative initiation was the response to the social demands and unrest given under the framework of semi-direct democracy which allowed for an institutional solution to them. Even though the law that called for the referendum defines its national character, in several articles it states that a regime of departamental autonomy will apply immediately after the new Constitution is ratified in those departments where the referendum question was approved by a simple majority of the vote. This dual interpretation with regards to the mandatory nature of the results — at the national or the departamental level — is added to the debate about the nature of the autonomies.The party of the government, whose position won in the referendum and won a majority of the constitutional assembly, sketches a proposal that includes different versions of autonomy — indigenous, regional, provincial, cantonal, communal — that run counter, in some instances, to the departamental autonomies. In sum, the referendum on departamental autonomy, far from solving the problem, has transfered it to the constitutional assembly which puts at risk the democratic legitimacy of its decisions given that the new constitution must answer the demands of diverse political and social actors. Aside from these dynamics, this experience of citizen participation in the decisiom-making process is an example of the positive impact of an institutional reform in the strengthening of the democratic legitimacy and the efficacy of political institutions.

    Full Text Available INTRODUCTION: American tegumentary leishmaniasis (ATL, including mucocutaneous leishmaniasis (MCL and localized cutaneous leishmaniasis (LCL, is endemic in Bolivia. We describe the results of active surveillance of ATL from 2001 to 2006 and assess demographic data related to ATL epidemiology in the Yungas valleys. METHODS: Community-based active ATL surveillance was performed by the institutions SERVIR, CÁRITAS, and the Health Services Department of La Paz, whose files were reviewed retrospectively. A cross-sectional survey was carried out to assess demographic data in two communities. RESULTS: Two thousand nine hundred nine cases of ATL were detected from 2001 to 2006: 2,488 (85.5% corresponded to LCL and 421 (14.5% to MCL. A reduction in the proportion of mucosal cases was observed between 2001 and 2006. The proportion of MCL cases increased with age and was higher among males (15.5% versus 12.1%, p=0.018. The rate of positivity via direct observation of the parasite in dermal scrapings and in parasite cultivation was significantly higher for LCL than for MCL (p<0.001 and p=0.009, respectively. The rate of reactivity in the leishmanin skin test was higher in the group with mucosal lesions (p=0.012. The cross-sectional survey showed that 40% of the families had emigrated from the Altiplano. CONCLUSIONS: It is necessary to undertake continuous case detection of ATL in the area, where the disease presents a high rate of mucosal cases. Increasing incidence seems to be associated with immigration and continuous deforestation to expand the crop-growing areas.

    Seven million children under 5 years of age died worldwide in 2011, and one-third had malnutrition. Latin America and Caribbean countries stand out for the notable improvement of their health and nutrition situation, particularly in pregnant women and young children. Nutrition-sensitive interventions such as promoting food security, women's empowerment, social safety nets, clean water, and sanitation, among others, are critical for success. In Bolivia, the program Desnutrición Cero (Malnutrition Zero) was able to reduce mortality from severe malnutrition after 5 years from 25% to less than 5%, based on widespread implementation of the World Health Organization 10-steps protocol for hospitalized care and the application of community management. The Economic Commission for Latin America estimated the cost of malnutrition for Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, Panama, and the Dominican Republic as US $6,658 million. Approximately 1 million children have dropped out of school because of malnutrition, and as a result, malnourished children have 2 years less schooling, which brings social and economic losses not only to those affected but to society at large. National and international nutrition and food programs developed over the past 50 years have been implemented as integral components of broader strategies of primary healthcare and education, oriented toward preventing deaths and improving the quality of life of low-socioeconomic-status groups. Treating hundreds or thousands of affected children will not solve the global public health problem of malnutrition. Access to adequate amounts of quality foods represents a basic human right and is a necessary precondition for health. In turn, good nutrition and health are prerequisites for human, social, and economic development.

  20. Constraining Glacial Runoff Contributions to Water Resources in the Cordillera Real, Bolivia using Environmental Tracers

    Warming temperatures in recent decades have contributed to substantial reductions in glaciers in many mountain regions around the globe, including the South American Andes. Melting of these glaciers taps water resources accumulated in past climates, and the diminishing ice marks a decrease in a nonrenewable water source that begs the question: how will future water supplies be impacted by climate change. Water resource management and climate adaptation efforts can be informed by knowledge of the extent to which glaciers contribute to seasonal streamflows, but remote locations and scant monitoring often limit this quantification. In Bolivia, more than two million people draw water from watersheds fed, in part, by glaciers. The amount to which these glaciers contribute to the water supply, however, is not well constrained. We apply elemental and isotopic tracers in an end-member mixing model to quantify glacial runoff contributions to local water supplies. We present oxygen and deuterium isotopes and major anion concentrations (sulfate and chloride) of shallow groundwater, streams, reservoirs, small arroyos, and glacial runoff. Isotopic and anion mixing models suggest between 45-67% of the water measured in high altitude streams originated from within the glacial footprint during the 2011 wet season, while glacial runoff contributed about 42-53% of the water in reservoirs in the 2012 dry season. Data also show that shallow groundwater is connected to glacial-fed streams. Any future decrease in glacial runoff may contribute to a reduction in surface water supplies and lower groundwater levels downstream, perhaps below the depth of hand-dug wells common in rural communities.

    All over the world a lot of cities are located in flood-prone areas and million of people are exposed to inundation risk. To cope with that the social safety demands efficient civil protection structures able to reduce flood risk by issuing warnings. This task requires civil protection organisms to adopt systems able to support their activities in predicting floods and rainfall impacts. For this reason flood early warning systems, based on rainfall observations and predictions, has become very useful because they are able to provide in advance a quantitative evaluation of possible effects in term of discharge and peak flow. Traditionally those forecasting systems use hydrologic models coupled with meteorological models to forecast discharge in relevant river sections and are called hydro-meteorological chains. In order to have a better representation of the flood dynamics, these hydro-meteorological chains can be expanded to include bi-dimensional hydraulic models where the level exposure is high or flow singularities (e.g. junctions, deltas, etc.) require more accurate investigation. That information allows the generation of real-time inundation scenarios that can be used by civil protection and authorities to estimate impact on population and take counter-measures. The new real-time flood impact forecasting chain consists of a suite of hydrometeorological tools that combines meteorological models, a disaggregation tool and a fully distributed hydrological model and a bidimensional hydraulic model that produces inundation scenarios in the most exposed river segments of the flood plain and a scenario tool that allows the assessment of assets involved. The complete modelling chain has been implemented in the Chapare watershed in Bolivia and it is managed by the Dewetra platform, which since 2013 is used by the Civil Defense and National Meteorological service as the main national Early Warning supporting tool.

  3. Assessing adaptation – Climate change and indigenous livelihood in the Andes of Bolivia

    Full Text Available Based on a case study of Charazani – Bolivia, this article outlines the understanding of adaptive strategies to cope with climate change and its impact on environmental and socioeconomic conditions that are affecting rural livelihoods. Mainly qualitative methods were used to collect and analyze data following the framework for vulnerability assessments of a socio-ecological system. Climate data reveals an increase of precipitation and temperature during the last decades. Furthermore the occurrence of extreme weather events, particularly drought, frost, hailstorms and consequently landslides and fire are increasing. Local testimonies highlight these events as the principle reasons for agricultural losses. This climatic variability and simultaneous social changes were identified as the drivers of vulnerability. Yet, several adaptive measures were identified at household, community and external levels in order to cope with such vulnerability; e.g. traditional techniques in agriculture and risk management. Gradually, farmers complement these activities with contemporary practices in agriculture, like intensification of land use, diversification of irrigation system and use of artificial fertilizers. As part of a recent trend community members are forced to search for new off-farm alternatives beyond agriculture for subsistence. Despite there is a correspondingly large array of possible adaptation measures that families are implementing, local testimonies point out, that farmers often do not have the capacity and neither the economical resources to mitigate the risk in agricultural production. Although several actions are already considered to promote further adaptive capacity, the current target is to improve existing livelihood strategies by reducing vulnerability to hazards induced by climate change.

    Full Text Available Background: Mobile health (m-health work in low and middle-income countries (LMICs mainly consists of pilot programmes with an unclear path to scaling and dissemination. We describe the deployment and testing of an m-health platform for non-communicable disease (NCD self-management support in Bolivia. Methods: 364 primary care patients in La Paz with diabetes or hypertension completed surveys about their use of mobile phones, health and access to care. 165 of those patients then participated in a 12-week demonstration of automated telephone monitoring and self-management support. Weekly Interactive Voice Response (IVR calls were made from a platform established at a university in La Paz, under the direction of the regional health ministry. Results: 37% of survey respondents spoke indigenous languages at home, and 38% had six or fewer years of education. 82% had a mobile phone; half (45% used text messaging with a standard phone, and 9% had a smartphone. Smartphones were least common among patients who were older, spoke indigenous languages, or had less education. IVR programme participants completed 1007 self-management support calls, with an overall response rate of 51%. IVR call completion was lower among older adults, but was not related to patients’ ethnicity, health status or healthcare access. IVR health and self-care reports were consistent with information reported during baseline interviews. Patients’ likelihood of reporting excellent, very good, or good health (versus fair or poor health via IVR increased during programme participation, and was associated with better medication adherence. Patients completing follow-up interviews were satisfied with the programme, with 19/20 (95% reporting that they would recommend it to a friend. Conclusions: By collaborating with LMICs, m-health programmes can be transferred from higher-resource centres to LMICs and implemented in ways that improve access to self-management support among people

  5. Biotic nitrosation of diclofenac in a soil aquifer system (Katari watershed, Bolivia).

    2016-09-15

    Up till now, the diclofenac (DCF) transformation into its nitrogen-derivatives, N-nitroso-DCF (NO-DCF) and 5-nitro-DCF (NO2-DCF), has been mainly investigated in wastewater treatment plant under nitrification or denitrification processes. This work reports, for the first time, an additional DCF microbial mediated nitrosation pathway of DCF in soil under strictly anoxic conditions probably involving codenitrification processes and fungal activities. This transformation pathway was investigated by using field observations data at a soil aquifer system (Katari watershed, Bolivia) and by carrying out soil slurry batch experiments. It was also observed for diphenylamine (DPA). Field measurements revealed the occurrence of NO-DCF, NO2-DCF and NO-DPA in groundwater samples at concentration levels in the 6-68s/L range. These concentration levels are more significant than those previously reported in wastewater treatment plant effluents taking into account dilution processes in soil. Interestingly, the p-benzoquinone imine of 5-OH-DCF was also found to be rather stable in surface water. In laboratory batch experiments under strictly anoxic conditions, the transformation of DCF and DPA into their corresponding N-nitroso derivatives was well correlated to denitrification processes. It was also observed that NO-DCF evolved into NO2-DCF while NO-DPA was stable. In vitro experiments showed that the Fisher-Hepp rearrangement could not account for NO2-DCF formation. One possible mechanism might be that NO-DCF underwent spontaneous NO loss to give the resulting intermediates diphenylaminyl radical or nitrenium cation which might evolve into NO2-DCF in presence of NO2 radical or nitrite ion, respectively.

  6. Characteristics of the aerial regime of an aridisol at the central high plateau of Bolivia

    International Nuclear Information System (INIS)

    In this work, the aerial regime of an aridisol with a loam clay-sandy texture of the central area of the high plateau of Bolivia, was determined as a function of the monthly volumetric moisture (using mean values) and the total porosity of the horizons Ap (0-19 cm), Bt (19-49 cm) and Cca (49-70 cm), Bt (19-49 cm) and Cca (49-70 cm). Values of moisture were determined during three year: 1983-84, 1984-5 and 1985-86 with the neutron probe. Fluctuations of the soil air content during the research period in the Ap and Bt horizons were strictly dependant on the precipitations and their seasonal variations due to porosity which was considered constant. Because this work was made in a soil with natural vegetation cover and without physical changes produced by tillage. The soil air content in the sandy Ap horizon showed higher values and greater difference (4-27%) than inferior horizons rich in clay (2-14%). The results were compared with quotes from the Czechoslovakian literature on the requirement of soil air content for certain crops: 15-35% for potatoes, 10-15% for cereals and 5-10% for pastures. This aridisol showing certain properties as clay horizons from 20 cm depth, unstable structure and insufficient air contents, can only be used for cereals and pastures. The use of these soils could be extended to crops with greater air requirements, if the water and aerial regimes are improved with the help of subsoilers, deepening the top soil and incorporating manure and green manure for improving the soil structure and porosity

    During the period of the Transatlantic Slave Trade (TAST) some enslaved Africans were forced to move to Upper Peru (nowadays Bolivia). At first they were sent to Potosí, but later to the tropical Yungas valley where the Spanish colonizers established a so-called “hacienda system” that was based on slave labor, including African-descendants. Due to their isolation, very little attention has been paid so far to ‘Afro-Bolivian’ communities either within the research field of TAST or in genetic population studies. In this study, a total of 105 individuals from the Yungas were sequenced for their mitochondrial DNA (mtDNA) control region, and mitogenomes were obtained for a selected subset of these samples. We also genotyped 46 Ancestry Informative Markers (AIM) in order to investigate continental ancestry at the autosomal level. In addition, Y-chromosome STR and SNP data for a subset of the same individuals was also available from the literature. The data indicate that the partitioning of mtDNA ancestry in the Yungas differs significantly from that in the rest of the country: 81% Native American, 18% African, and 1% European. Interestingly, the great majority of ‘Afro-descendant’ mtDNA haplotypes in the Yungas (84%) concentrates in the locality of Tocaña. This high proportion of African ancestry in the Tocaña is also manifested in the Y-chromosome (44%) and in the autosomes (56%). In sharp contrast with previous studies on the TAST, the ancestry of about 1/3 of the ‘Afro-Bolivian’ mtDNA haplotypes can be traced back to East and South East Africa, which may be at least partially explained by the Arab slave trade connected to the TAST.

    This paper emphasize on the observational investigation of an ice-covered volcano and two glaciated mountains in the Central Andes from 1984 to 2011. Annual snowlines of the Nevado Sajama in the Cordillera Occidental and the Nevado Cololo and the Nevado Huanacuni in the Cordillera Apolobamba in Bolivia were calculated using remote sensing data. Landsat TM, Landsat ETM+, and LISS-III images taken during the end of dry season were used in this study. Changes in the highest annual snowline during May-September is used an indirect measure of the changes in the equilibrium line altitude of the glaciers in the outer tropics. We tried to understand the combined influence of the El Niño-Southern Oscillation and the Pacific Decadal Oscillation on the variations in the annual snowline altitude of the selected glaciers. Meteorological data in the form of gridded datasets were used for calculating the anomalies in precipitation and temperature during the study period. It is found that the glaciated areas were fluctuated with the occurrence of warm and cold phase of ENSO but the magnitude of the influence of ENSO is observed to be controlled by the phase changes of PDO. Snowline of the Nevado Sajama fluctuated heavily when cold and warm phases of ENSO occur during the cold and warm regimes of PDO, respectively. Nevado Cololo and Nevado Huanacuni are showing a continuous retreating trend during the same period. This clearly indicates that the changes in the Pacific SST patterns have more influence on glaciers in the Cordillera Occidental compared with those in the Cordillera Oriental of the Bolivian Andes.

    The Bolivia-Brazil Natural Gas Pipeline - GASBOL - begins in the city of Santa Cruz of La Sierra, in Bolivia, arriving in Canoas (RS), in Brazil, traveling an extension of 3.150 Km. Of this total, 2.593 Km are in Brazilian soil. In the kilometer 526+500m of the south spread, GASBOL crosses the reservoir of the Vocoroca's dam (COPEL), which had its operational level reduced, in face of the station of the droughts that usually reaches the area in the months of March to September. The lowing of the reservoir caused the turn of the course of Fojo River (Sao Joaozinho River) to its natural quota, forming a waterfall, whose hydraulic gradient caused the removal of the sediment and part of the foundation soil, discovering the pipe that was with space free from approximately 13 m of length. This paper discusses the solution adopted, as well as the several details of the recovery project, besides geotechnical and hydraulic studies and the aspects of safety of the Gas Pipeline. (author)

    Full Text Available (1 The high-altitude (4,500+ m Andean mountain range of north-western Bolivia contains many peatlands. Despite heavy grazing pressure and potential damage from climate change, little is known about these peatlands. Our objective was to quantify carbon pools, basal ages and long-term peat accumulation rates in peatlands in two areas of the arid puna ecoregion of Bolivia: near the village of Manasaya in the Sajama National Park (Cordillera Occidentale, and in the Tuni Condoriri National Park (Cordillera Real. (2 We cored to 5 m depth in the Manasaya peatland, whose age at 5 m was ca. 3,675 yr. BP with a LARCA of 47 g m-2 yr-1. However, probing indicated that the maximum depth was 7–10 m with a total estimated (by extrapolation carbon stock of 1,040 Mg ha-1. The Tuni peat body was 5.5 m thick and initiated ca. 2,560 cal. yr. BP. The peatland carbon stock was 572 Mg ha-1 with a long-term rate of carbon accumulation (LARCA of 37 g m-2 yr-1. (3 Despite the dry environment of the Bolivian puna, the region contains numerous peatlands with high carbon stocks and rapid carbon accumulation rates. These peatlands are heavily used for llama and alpaca grazing.

    Full Text Available To increase our knowledge of the natural susceptibility of Triatoma infestans to an organophosphate insecticide, we performed toxicological and biochemical studies on three sylvatic populations from Bolivia and two populations from domestic dwellings from Bolivia and Argentina. Fifty-per-cent lethal doses (LD50 were determined based on the topical application of fenitrothion on first instar nymphs and mortality was assessed at 24 h. Both type of populations exhibited LD50ratios significantly higher than 1 with a range of the values (1.42-2.47; the maximum value were found in a sylvatic (-S population, Veinte de Octubre-S. Samples were biochemically analysed using a glutathione S-transferase activity assay. The highest significant activity was obtained for Veinte de Octubre-S and the lowest activity was obtained for the reference population (102.69 and 54.23 pmol per minute per mg of protein respectively. Two out of the three sylvatic populations (Veinte de Octubre-S and Kirus Mayu-S exhibited significantly higher glutathione S-transferase activity than that of the reference population. Based on this analysis of the natural susceptibility of this organism to organophosphate insecticides, continental and focal surveys of organophosphate susceptibility should be conducted to evaluate the evolution and distribution of this phenomenon.

    The Central Andes of southern Bolivia is a highly seismic region due to the faults present in this area which eventually could generate earthquakes up to 8.5 Mw. Nevertheless most of them are shallow and have low magnitude. In 2013, an earthquake of 5.0 Mw ocurred in Santa Cruz de la Sierra, it was followed by five aftershocks in the two months after the mainshock. Distances between epicenters of the aftershocks and the mainshock are up to 34 km, which is greater than expected for an earthquake of this magnitude. Additionaly the uncertainty of the epicenters is around 20 km; this scenario is not suitable for studies looking to determine the seismogenic fault orientation. Using data from South American stations of the international network of the Incorporated Research Institutions dor Seismology (IRIS) and the relative location technique, that uses the surface waves (usually the clearest wave in noisy sismograms), the epicenters of five aftershocks of the Santa Cruz series were determinated in relation the mainshock. This method enabled to achieve epicentral locations with uncertainties smaller than 2 km, distances between the aftershocks and the mainshock are up to 7 km, in accordance with the magnitude of the earthquake. The result of the relative location showed a N - S trend of the epicenters in agreement with the location and orientation of the Mandeyapecua fault, the largest reverse fault in Bolivia. Key words: Relative location, Surface waves

    2013-10-01

    Full Text Available The dominant paradigm in rural water provision in Bolivia has focused on the provision of infrastructure, whether by government agencies or international cooperation groups. However, the investment in infrastructure has led neither to universal access for all Bolivians nor to consistently high levels of services for those who do have access to a water system. This paper will describe the transition of one international non-profit organisation, Water For People, from supporting dispersed water projects throughout the country towards targeted support of water services at the municipal level, aiming to support permanent universal services. The institutional evolution – including changes in governance, implementation strategy, donor base, and indicators of success – that allowed field programmes to shift from projects to services provides the context for the change of approach in Bolivia. A discussion of the various aspects that have changed in the organisation’s operations in seven municipalities in Bolivia, from the scale of intervention, to municipal-wide planning information and tools, to support to service providers and service authorities, and an increased focus on post-construction monitoring, demonstrates how the Everyone, Forever approach is resulting in a more service- delivery-oriented approach in Bolivia.

    Subduction of the Nazca plate in the north central Andes beneath southern Peru and northern Bolivia is of prime importance because of the role it plays in the evolution of topographic features since the late Eocene (~40 Ma). Previous studies based on slab event locations constrained only with teleseismic data defined a broad area of flat slab subduction in central and southern Peru, which transitions to a normally dipping slab beneath the northernmost Altiplano Plateau. We present earthquake locations and focal mechanisms using data from two temporary arrays: the network of 50 broadband seismic stations that were part of the NSF-Continental Dynamics-funded project 'CAUGHT' (Central Andean Uplift and the Geodynamics of High Topography) and the 40 station NSF- Geophysics funded 'PULSE' array (PerU Lithosphere and Slab Experiment). Our earthquake locations provide new information about the geometry of subducting Nazca slab between 13°S to 18°S. A significant clustering of intermediate depth earthquakes at ~15.5°S and 18°S suggests strong and localized release of tectonic stress in the slab perhaps due to bending and unbending. There are not enough intra-slab events at depth greater than 100 km to constrain the flat slab width north of 14°S. Our analyses indicate that the flat slab is at least 10 to 12 km shallower than the previous estimates (e.g. Cahill and Isacks, 1992; Ramos, 2009). Focal mechanisms and stress axis orientation of slab events at ~15.5°S indicate down-dip extension, where the dip changes from subhorizontal to steeply dipping slab. The continuity in the trend of stress suggests that the slab is deformed but not torn where it transitions from flat to steeply dipping. Data from local slab events will eventually be incorporated into a local tomographic body wave inversion to better constrain the velocity structure of the mantle lithosphere and asthenosphere below the Altiplano. This in turn will provide the valuable information on the process

    An overwhelming number of applications depend on reliable precipitation estimations. However, over complex terrain in regions such as the Andes or the southwestern Amazon, the spatial coverage of rain gauges is scarce. Two reanalysis datasets, a satellite algorithm and a scheme that combines surface observations with satellite estimations were selected for studying rainfall in the following areas of Bolivia: the central Andes, Altiplano, southwestern Amazonia, and Chaco. These Bolivian regions can be divided into three main basins: the Altiplano, La Plata, and Amazon. The selected reanalyses were the Modern-Era Retrospective Analysis for Research and Applications, which has a horizontal resolution (~ 50 km) conducive for studying rainfall in relatively small precipitation systems, and the Climate Forecast System Reanalysis and Reforecast, which features an improved horizontal resolution (~ 38 km). The third dataset was the seventh version of the Tropical Rainfall Measurement Mission 3B42 algorithm, which is conducive for studying rainfall at an ~ 25 km horizontal resolution. The fourth dataset utilizes a new technique known as the Combined Scheme, which successfully removes satellite bias. All four of these datasets were aggregated to a coarser resolution. Additionally, the daily totals were calculated to match the cumulative daily values of the ground observations. This research aimed to describe and compare precipitations in the two reanalysis datasets, the satellite-algorithm dataset, and the Combined Scheme with ground observations. Two seasons were selected for studying the precipitation estimates: the rainy season (December-February) and the dry season (June-August). The average, bias, standard deviation, correlation coefficient, and root mean square error were calculated. Moreover, a contingency table was generated to calculate the accuracy, bias frequency, probability of detection, false alarm ratio, and equitable threat score. All four datasets correctly

    Assessing climatological trends and extreme events requires high-quality data. However, for many regions of the world, observational data of the desired quality is not available. In order to eliminate errors in the data, quality control (QC) should be applied before data analysis. If the data still contains undetected errors and quality problems after QC, a consequence may be misleading and erroneous results. A region which is seriously affected by observational data quality problems is the Central Andes. At the same time, climatological information on ongoing climate change and climate risks are of utmost importance in this area due to its vulnerability to meteorological extreme events and climatic changes. Beside data quality issues, the lack of metadata and the low station network density complicate quality control and assessment, and hence, appropriate application of the data. Errors and data problems may occur at any point of the data generation chain, e.g. due to unsuitable station configuration or siting, poor station maintenance, erroneous instrument reading, or inaccurate data digitalization and post processing. Different measurement conditions in the predominantly conventional station networks in Bolivia and Peru compared to the mostly automated networks e.g. in Europe or Northern America may cause different types of errors. Hence, applying QC methods used on state of the art networks to Bolivian and Peruvian climate observations may not be suitable or sufficient. A comprehensive amount of Bolivian and Peruvian maximum and minimum temperature and precipitation in-situ measurements were analyzed to detect and describe common data quality problems. Furthermore, station visits and reviews of the original documents were done. Some of the errors could be attributed to a specific source. Such information is of great importance for data users, since it allows them to decide for what applications the data still can be used. In ideal cases, it may even allow to

    The Altiplano-Puna Volcanic Complex (APVC) of the Central Andes has produced prodigious silicic volcanism (at least 11,000 km3 of magma) over the last 10 Ma including some of the largest known ignimbrites on Earth. Despite excellent exposure, little previous work had been conducted on the timing and distribution of ignimbrite volcanism in the Lípez region of southwestern Bolivia, the heart of the APVC. To address this deficiency we have performed ~612 single crystal laser-fusion 40Ar/39Ar analyses from 39 pumice and bulk matrix samples collected from the main ignimbrite units within the Lípez region. Geochemistry of pumice and mineral samples, and paleomagnetic data are also being used to correlate individual ignimbrite units. Our new 40Ar/39Ar results establish new or refined eruption ages (with 2σ error) from the Vilama caldera at 8.41±0.02 Ma, Pastos Grandes caldera at 5.45±0.02 and 2.94±0.01 Ma, and Guacha caldera at 5.65±0.01, and 3.57±0.02 Ma. New ages were also determined for eruptions from the Panizos ignimbrite shield (6.86±0.03 Ma), Juvina ignimbrite shield (5.23±0.01 Ma), and the Laguna Colorado ignimbrite shield (2.21±0.05 and 1.95±0.03 Ma). The oldest ignimbrite we have found in the area is 10.33±0.64 Ma, a local unit beneath the Vilama ignimbrite. The youngest units have been identified west of the Guacha caldera with eruption ages of 1.70±0.6 Ma and 0.70±0.01 Ma. These results demonstrate that ignimbrite-producing eruptions in the Lípez region span the age of APVC volcanism previously established, with the largest eruptions occurring from long-lived, cyclic supervolcano caldera systems like Guacha and Pastos Grandes. The aggregate data from the APVC support the hypothesis that the APVC developed predominantly during distinct pulses of massive ignimbrite eruptions at ~8, 6, and 4 Ma and attest to episodic behavior of the magmatic system. Ignimbrites of geothermal presence and active local surface deformation suggest that the magma

METHODS: The immunofluorescent antibody test (IFAT was used for IgG and IgM anti-Trypanosoma cruzi antibodies in filter paper bloodspot eluates from 128 subjects (73 females, 55 males selected by systematic sampling. Concerning each subject age, gender, birthplace, occupation, duration of residence and building materials used in their houses were recorded. Vectors were captured both in domestic and peridomestic environments. RESULTS: Seropositive, 12.5% (16/128: females, 15.1% (11/73; males, 9.1% (5/55. Average time of residence: 6.1 years for the whole population sample and 7.4 years for the seropositive subjects. Most houses had adobe walls (76.7% , n= 30, galvanized iron rooves (86.7% and earthen floors (53.4% 80% of the walls had crevices. One hundred forty seven specimens of Triatoma infestans were captured, of which 104 (70.7% were domestic, and 1 peridomestic Triatoma sordida. Precipitin host identification: birds, 67.5%; humans, 27.8%; rodents, 11.9%; dogs, 8.7%; cats, 1.6%. House infestation and density indices were 53.3 and 493.0 respectively. We found 21 (14.3% specimens of T. infestans infected with trypanosomes, 18 (85.7% of which in domestic environments. DISCUSSION: The elements for the vector transmission of Chagas disease are present in Avaroa/Primer de Mayo and the ancient custom of keeping guinea pigs indoors adds to the risk of human infection. In neighboring Cochabamba, due to substandard quality control, contaminated blood transfusions are not infrequent, which further aggravates the spread of Chagas disease.

    The San José mine, Oruro, Bolivia is known for provided a broad diversity of minerals. The San José Sn deposit is a Sn-Ag deposit composed of veins hosted in a complex of Miocene domes from monzonitic to dioritic composition within rhyolitic volcanic rocks hosted in Tertiary sedimentary rocks. Advanced argillitic alteration. is widespread in the surroundings of the deposit. Kaolinitization reach industrial importance and the kaolinitized rock is exploited, however it was not already been characterised. In this study we present a preliminary mineralogical and thermal characterization to determine the industrial applications of these kaolinitic materials. A sampling of the kaolinitized rocks in outcrops from the mining area was undertaken. The chemical composition of major and trace elements was determined by X-ray fluorescence (XRF). Mineralogy was obtained by powder diffraction X-ray (XRD) and infrared spectroscopy (FTIR). Quantitative determination of phases was obtained by the Rietveld refinement method using the Fullprof software. Thermal properties were determined by differential thermal analysis-thermo gravimetry (DTA -TG) and dilatometry. Mineral phases determined are mainly quartz (54-55 wt. %), kaolinite (7-8 wt. %), K-feldspar (8-19 wt. %), muscovite (16-17 wt. %), plagioclase up to 3 wt. %, alunite up to 8 wt% and gypsum up to 4 wt%. DTA -TG show a first endothermic event related to the dehydration of gypsum, with a loss weight of 0.4 wt%. An endothermic peak corresponding to the loss of the OH- groups of kaolinite occurs about 520 °C and an exothermic, at 980 °C, due to the crystallization of the mullite phase. The endothermic peak is attributed to the transformation of kaolinite in metakaolinite: Al2Si2O5 (OH)4  Al2Si2O7 + 2H2O and the dehydroxilation of alunite; the loss weight associated with this event is 2.9-3.2 wt%. The exothermic peak is caused by the formation of mullite: 3Al2Si2O7  Al6Si2O13 + 4SiO2. Another loss weight, of 3wt%, is

    The internal lining in gas pipelines aims the reduction of roughness and, consequently, the friction factor, therefore resulting in a reduction of pressure drop in natural gas flowing. During Bolivia-Brazil gas pipeline basic design, the cost benefit of internal coating was analyzed, in terms of friction factor reduction and distances between Compressor Stations. It was observed an increase of transport capacity and reduction of compressors' power, thus leading to its utilization. Since the pipeline is already in operation, using a SCADA system with Advanced Functions, a comparison between the current real friction factor in the pipeline with that theoretical values used during the design phase becomes possible. Through this comparison, it is possible to evaluate internal coating's efficiency, quantifying its real benefit for gas pipelines. (author)

    Este artículo propone que descolonizar es desmontar, de manera radical, el actual sistema de valores y las instituciones que los sustentan. En Bolivia, este es un sistema de dominación que es neocolonial y racista. Aunque se vive la descolonización de la sociedad, desde el año 2009 el gobierno del MAS quebró la posibilidad de una descolonización del Estado. Sin embargo, el gobierno proclama el triunfo de la descolonización sobre la base de que Evo Morales es un presidente indígena. Para dimensionar el alcance de estos debates, el artículo estudia otras corrientes de pensamiento acerca de la descolonización, tales como el indianismo y el katarismo, y el multiculturalismo de Xavier Albó.

    A 5-month field study on both the distribution and ecology of Callimico goeldii was carried out in the seasonally dry rain forest of north-western Bolivia. The species was found to be very sparsely distributed (approximately one group per 4 km2) in isolated groups of about 6 animals throughout the study area. Callimico was found to associate a great deal with two species of Saguinus that inhabit the same region in greater densities. It appears to be a habitat specialist, preferring low-lying and damp, but well-drained, bamboo forest and spending nearly all its time within 3 m of ground level, travelling mainly by vertical clinging and leaping. We believe that this ecological specialisation accounts for the species' discontinuous micro-distribution, and that this in turn is related to Callimico's distinctive pattern of social organisation.

    Artisanal gold mining is the main economic activity in the Yani district, Northern Bolivia. In this area abundant orogenic gold deposits constituted by quartz veins hosted in paleozoic turbiditic series that contain either free gold or associated with pyrite. Gold is recovered in processing plants by gravimetric methods using shaking tables in several communities of this district. Previously, miners ground the mineral in ball mills together with mercury. The present study aims to evaluate the effect of mercury used in the gold recovering process to the environment and human health in the Yani district. The assessment was based on the analysis of human hair, sediments and water from the river nearby the processing plant and drinking water from the fountain that supplies these communities. 47 samples of hair from miners and other people from the Yani and Señor de Mayo communities were obtained in 2014 and 52 samples in 2015. All were analysed to evaluate the mercury exposure in these places. The results from the 2014 sampling show a wide range of Hg concentration in hair, especially in Señor de Mayo, with values up to 136 μg/g THg. However, in 2015 among the 43 residents in Señor de Mayo, 29 (67%) exhibit concentrations higher than 2 μg/g THg, with an average value of 5.36 μg/g THg. On the other hand, in Yani only 40% have concentrations above 2 μg/g THg, with an average value of 2.34 μg/g THg. The content in Hg in most of the hair samples exhibit values above the tolerable limits established by the US Environmental Protection Agency (1 μg/g Hg) and the World Health Organisation (WHO, 2 μg/g Hg). These high Hg concentrations are found not only in miners but also in the other members of the community, in spite of low fish consumption in this area. Part of the hair was analysed before and after cleaning. Usually in the second case the content of Hg is reduced, but still show high Hg levels, then probably the atmosphere is polluted with Hg and population is

    Full Text Available The aim of this paper is to explore possible links between forest cover change and characteristics of social-ecological systems at sub-national scale based mainly on census data. We assessed relationships between population density, poverty, ethnicity, accessibility and forest cover change during the last decade for four regions of Bolivia and the Lao PDR, combining a parcel-based with a cell-based approach. We found that accessibility is a key driver of forest cover change, yet it has the effect of intensifying other economic and policy-related underlying drivers, like colonization policies, cash crop demand, but also policies that lead to forest gain in one case. Poverty does not appear as a driver of deforestation, but the co-occurrence of poverty and forest loss driven by external investments appears critical in terms of social-ecological development. Ethnicity was found to be a moderate explanatory of forest cover change, but appears as a cluster of converging socio-economic characteristics related with settlement history and land resource access. The identification of such clusters can help ordering communities into a typology of social-ecological systems, and discussing their possible outcomes in light of a critical view on forest transition theory, as well as the relevance and predictive power of the variables assessed. Résumé: L’objectif de cet article est d’explorer les liens entre le changement de la couverture forestière et les caractéristiques des systèmes socio-écologiques à l’échelle nationale, principalement à l’aide de données de recensement.

    Current legislation transferred public tertiary hospitals in Bolivia from the Municipalities to the Regional Level. However, the Regional Governments are experiencing technical and financial constraints to reform infrastructure, modernize equipment and introduce reforms to allow better governance, management and sustainability of these hospitals. This articles summarizes the recent experience of the Government of Santa Cruz de la Sierra in Bolivia where five tertiary hospitals and blood bank (most of them in precarious working conditions) has been transferred in 2012 from the Municipal Government of Santa Cruz (the capital) to the Regional Government of Santa Cruz. To face the challenges, the Regional Government of Santa Cruz implement several improvements, such as contract new clinical and administrative personal, increases hospital budgetary autonomy, outsource hospitals' auxiliary services, take measures to eliminate waiting lists and make several new investments to modernize and equip the hospitals. The World Bank was contracted to evaluated the future financial sustainability of these investments and to advice the Government to propose changes to increase the hospitals' management performance. The article describes the remaining challenges in these hospitals and the proposals from the World Bank Study. In the area of quality of care, the main challenge is to improve client satisfaction and continuous outcomes monitoring and evaluation according quality standards. In the area of financing, the challenge is how to assure the sustainability of these hospitals with the current level of health financing and the insufficient financial transfers from the National Government. In the area of Governance, reforms to streamline and simplify internal processes need to be introduced in order to establish mechanisms to increase transparency and accountability, allowing the hospital to have a good administration and adequate participation of the main actors in the guidance of

    Potosí, Bolivia, is the site of centuries of historic and present-day mining of the Cerro Rico, a mountain known for its rich polymetallic deposits, and was the site of large-scale Colonial era silver refining operations. In this study, the concentrations of several metal and metalloid elements were quantified in adobe brick, dirt floor, and surface dust samples from 49 houses in Potosí. Median concentrations of total mercury (Hg), lead (Pb), and arsenic (As) were significantly greater than concentrations measured in Sucre, Bolivia, a non-mining town, and exceeded US-based soil screening levels. Adobe brick samples were further analyzed for bioaccessible concentrations of trace elements using a simulated gastric fluid (GF) extraction. Median GF extractable concentrations of Hg, As, and Pb were 0.085, 13.9, and 32.2% of the total element concentration, respectively. Total and GF extractable concentrations of Hg, As, and Pb were used to estimate exposure and potential health risks to children following incidental ingestion of adobe brick particles. Risks were assessed using a range of potential ingestion rates (50-1000mg/day). Overall, the results of the risk assessment show that the majority of households sampled contained concentrations of bioaccessible Pb and As, but not Hg, that represent a potential health risk. Even at the lowest ingestion rate considered, the majority of households exceeded the risk threshold for Pb, indicating that the concentrations of this metal are of particular concern. To our knowledge, this is the first study to quantify key trace elements in building materials in adobe brick houses and the results indicate that these houses are a potential source of exposure to metals and metalloids in South American mining communities. Additional studies are needed to fully characterize personal exposure and to understand potential adverse health outcomes within the community.

    Full Text Available En este trabajo se describe el proceso de consolidación de la propiedad y el control de la gestión en los bancos que operaron en Bolivia durante el periodo de 1996 a 2006, y se evalúa de manera general el papel de los bancos extranjeros en el desarrollo del sistema bancario. El uso del concepto de subsidiaria extranjera en el país, más allá de la definición tradicional de sucursal extranjera, permite apreciar perspectivas diferentes a las habitualmente observadas sobre el desempeño de los bancos extranjeros en Bolivia. Adicionalmente, un análisis definido por las etapas de la evolución de la cartera, con aproximaciones a indicadores macro y micro, utilizando la información publicada por los bancos, posibilita también la observación de características sobresalientes y particulares en bancos nacionales y sucursales o subsidiarias extranjeras. El estudio llega a la conclusión de que los cambios más substanciales de la última década en el sistema bancario del país anfitrión, fueron protagonizados por las subsidiarias extranjeras, ya que sus modelos de negocio y actividades fueron más allá de la especialización en operaciones de comercio exterior o de carácter corporativo, pero también muestra cómo los cambios en las estrategias de sus casas matrices extranjeras pueden ser perniciosos para un sistema financiero de las características del boliviano.

  2. The geologic and geomorphologic evolution of Serranía Huanchaca, eastern Bolivia: The legendary ``Lost World''

    Science.gov (United States)

    Litherland, M.; Power, G.

    Serranía Huanchaca is a remote tableland in eastern Bolivia with an area of about 7000 km 2. It is bounded by precipitous cliffs which overlook the densely forested lowlands of the southern Amazonian basin. Descriptions of the cliffs by the English explorer Col. Fawcett formed the basis for the novel The Lost World by Arthur Conan Doyle. The serranía is composed mainly of unmetamorphosed arenaceous Proterozoic sediments which comprise the Huanchaca Group. This unconformably overlies a basement complex of schists and granites which were generated at c. 1300 Ma. The Huanchaca Group sediments are interpreted as fluvial deposits which were derived from the north. Around 900 Ma, these sediments were intruded by a continental tholeiitic sill and dike complex, while the marginal effects of the Aguapei Mobile Belt produced a pattern of monoclinal folds in the form of a structural basin. This basin was later infilled by sandstones of the Macacos Group, of possible Cretaceous age, and the entire sequence was affected by the Cretaceous post-Macacos episode of faulting, jointing and minor folding, accompanied by the formation of siliceous reefs of quartz breccia and chert. The geomorphologic evolution of the serranía can be related to successive Tertiary cycles of erosion which, in order of decreasing age, produced the Pega Pega, Paucerna, and San Ignacio planation surfaces and associated laterites as well as sandstones, cherts, and silcretes found locally over the serranía. The keel of more resistant Huanchaca Group quartzites has helped preserve the Pega Pega and Paucerna surfaces over the serranía; elsewhere in eastern Bolivia, these have been removed by the San Ignacio cycle of erosion.

    2015-12-01

    We describe the first Miocene turtle remains from Bolivia, which were collected from the late middle Miocene (13.18-13.03 Ma) of Quebrada Honda, southern Bolivia. This material includes a large scapula-acromion and fragmentary shell elements conferred to the genus Chelonoidis (Testudinidae), and a left xiphiplastron from a pleurodire or side-necked turtle, conferred to Acanthochelys (Chelidae). The occurrence of a giant tortoise and a freshwater turtle suggests that the paleoelevation of the region when the fossils were deposited was lower than has been estimated by stable isotope proxies, with a maximum elevation probably less than 1000 m. At a greater elevation, cool temperatures would have been beyond the tolerable physiological limits for these turtles and other giant ectotherm reptiles.

    This paper aims to clarify and understand the reasons for the current economic policy and trade between Bolivia and Brazil, the latter represented by PETROBRAS, as the year 2006. Focuses on the regulatory change in Bolivia that culminated in a period of re-nationalization of its mineral wealth as opposed to international interests, including Brazilians, and agreements entered into during the opening of the market in the country. Thus, set in the Latin American actual situation, we undertake to understand the process and its consequences for Brazil, which, even with the third largest gas reserves in the region, in the short term, it follows as an importer of this feature. To have a concrete base with foundations and analyze what happens today, we must understand the political history of Bolivia and their internal changes. So we divided the work into two parts: first, we analyze the neo liberal period, and the agreements signed with Brazil in the hydrocarbon sector, for mutual benefits. In the second part, we understand the political rise of Evo Morales and the nationalization process of national wealth and the consequent crisis that developed with the international oil companies, especially with PETROBRAS, to the final outcome on the price, production and export of gas.

    Full Text Available From the end of the nineteenth century until the middle of the twentieth, the Gran Chaco was a zone of conflict. Argentina, Bolivia and Paraguay exercised varied and competing influences in the region, reflecting the intentions of each nation to incorporate the Chaco forcibly as part of larger projects of industrialisation and colonisation. This study examines the implementation of these projects, as well as the resistance they generated in the face of the violence visited upon the inhabitants of the region, whether indigenous peoples, mestizos, or whites. From an anthropological perspective, the work also reassesses conflicts in the Chaco region as a problem in the history of inter-American relations, where non-governmental actors determine links between people and government. The article goes on to consider the national and regional contexts to conflict, in which frontiers and boundaries are further concepts and realities to be assessed.

Este trabajo busca conocer la ejecución de aquellas políticas y las resistencias generadas, en espacios que fueron tanto de concertaciones, como de conflictos frente al poder y a la violencia ejercida sobre sus pobladores, indios, mestizos y blancos. El objetivo es también contribuir a enriquecer la historia de las relaciones interamericanas, a través de una perspectiva antropológica, en donde actores no estatales configuran vínculos entre pueblos y gobiernos, y asimismo de una mirada que se dirija simultáneamente hacia la consideración de los contextos nacionales y regionales, en donde fronteras y límites son nociones y realidades a

  15. Late Quaternary geomorphic history of a glacial landscape - new sedimentary and chronological data from the Cordillera de Cochabamba (Bolivia)

    Throughout the Central Andes, glacial landscapes have long been used for the reconstruction of Late Quaternary glaciations and landscape evolution. Much work has focused on the Andes in Peru, Chile and the Bolivian Altiplano, whereas relatively little data has been published on glaciation history in the eastern Andean ranges and slopes. Even less is known with regard to the postglacial evolution of these glacial landscapes. In the Cordillera de Cochabamba (Bolivia), local maximum advances probably peaked around 20-25 ka BP and were followed by significant readvances between ~12-16 ka BP. This generally points to temperature controlled maximum glacial advances along the humid eastern slopes of the Central Andes, which is supported by glacier-climate-modelling studies. However, most studies include only marginal information with regard to the complex geomorphic and sedimentary situation in the Cordillera de Cochabamba. Furthermore, the chronological results are afflicted with several methodological uncertainties inherent to surface exposure dating and call for application of alternative, independent age dating methods. Therefore this study aims at i) documenting and interpreting the complex glacial geomorphology of the Huara Loma valley in the Cordillera de Cochabamba (Bolivia), ii) analyzing the involved units of glacial sediments, and iii) improving the chronological framework by applying optically stimulated luminescence (OSL) and radiocarbon dating (14C). For this purpose, geomorphic mapping was combined with field documentation of sedimentary profiles. The involved sediments were subject to geochemical and mineralogical analysis in order to deduce information on their erosional and weathering histories. In addition, the interpretation of OSL ages from glacial and proglacial sediments integrated several methodological procedures with regard to sample preparation and statistical analysis of the measurements in order to increase the degree of confidence.

  16. Evaluation of a polymerase chain reaction assay for the diagnosis of bovine Trypanosomosis and epidemiological surveillance in Bolivia

    International Nuclear Information System (INIS)

    Sporadic outbreaks of bovine Trypanosomiasis have been reported in Bolivia since 1996 when T.vivax and T.evansi were identified for the first time by parasitological means. However, comprehensive epidemiological information concerning T.vivax and T.evansi in the country is lacking. Current parasitological and serological diagnostic methods for Trypanosomiasis have important limitations either in their sensitivity or specificity, which can result in unreliable data when applied in epidemiological studies. PCR assays are a recently developed procedure that might help to overcome the constraints of parasitological and serological assays. Therefore, the objective of this study was to evaluate PCR assays as a diagnostic tool for epidemiological studies in Bolivia. PCR assays for diagnosis of Trypanosome infection in cattle were evaluated for their ability to detect Trypanosome DNA in blood spots samples collected from cattle in four different provinces from the Bolivian lowlands and the results compared with those obtained with standard parasitological (Micro Haematocrit Centrifugation Technique (HCT) and stained smears) and serological methods (Card Agglutination Test for T.evansi (CATT), and Antibody ELISAs for T.vivax and T. congolense). Kappa agreement analysis showed a significant agreement between PCR assays and results from parasitological methods but there was no agreement when PCR was compared with serological assays. Some samples from T.vivax smear positive animals were negative by PCR, therefore modifications to the PCR assay conditions were undertaken to try to improve agreement between PCR and parasitological assays. Changes in the template DNA concentration or the use of an alternative primer sets resulted in improvements in the PCR detection rate, but not all the parasitologically positive samples were detected by PCR. Results from PCR assays for T.vivax and T.evansi were combined with results from parasitological and serological assays to provide

    We present the application of a network transportation model, with capacity restrictions, to determine the minimal cost of supply of a group of markets at the Bolivia Brazil Gas Pipeline influence area, as a function of city gate price. We consider the potential of integration of pipeline transportation at the South Cone, looking forward to supply the Brazilian market. The city gate price consists of the sum of commodity price plus transportation tariffs over every gas pipeline through which the gas passes (except distribution pipelines). There is no distinction related to product quality (e.g. heating value) among suppliers, or among end uses (thermal, thermoelectric or chemical). The model is numerically solved by linear programming. Flow direction alternatives and transportation tariffs alternatives (postal and by zone) are proposed. The model allows, among other applications: identification of the lowest cost supply strategy, identification of network flow capacity bottlenecks, determination of operation and expansion marginal costs using dual solution analysis, investigation of alternative sceneries through sensibility analysis and appreciation of non-optimal solutions that might be attractive.

    Full text: In this work the presence of radon gas was determined, which is a radioactive contaminant that comes from underground, able to penetrate the houses. The danger is that when mixed air and when inhaled can cause serious damage to the lungs, for the short life time that has radon and progeny for decay, damaging the pulmonary alveoli and reducing breathing capacity of the habitants, then causing polycythemia in some cases. The study was carried out in homes in the city of Potosi, Bolivia located at 4000 m. The quantification of radon gas and progeny was performed with the equipment Alpha-Zaeller-2 (Az-2), quantification was realized in 6 zones of the city of Potosi, chosen randomly. In each zone were carried out measurements in 40 homes (2 rooms more permanent), both day and night, for a period of 3 days in two different seasons and with concentrations of average humidity of 20, 50 and 80%. The values obtained for each period vary depending on the season and 30 to 50% of the allowable values given by the EPA and Who for housing. (Author)

  19. Perception and Interpretation of Climate Change among Quechua Farmers of Bolivia: Indigenous Knowledge as a Resource for Adaptive Capacity

    2013-12-01

    Full Text Available We aim to explore how indigenous peoples observe and ascribe meaning to change. The case study involves two Quechua-speaking farmer communities from mountainous areas near Cochabamba, Bolivia. Taking climate change as a starting point, we found that, first, farmers often associate their observations of climate change with other social and environmental changes, such as value change in the community, population growth, out-migration, urbanization, and land degradation. Second, some of the people interpret change as part of a cycle, which includes a belief in the return of some characteristics of ancient or mythological times. Third, environmental change is also perceived as the expression of "extra-human intentionalities," a reaction of natural or spiritual entities that people consider living beings. On the basis of these interpretations of change and their adaptive strategies, we discuss the importance of indigenous knowledge as a component of adaptive capacity. Even in the context of living with modern science and mass media, indigenous patterns of interpreting phenomena tend to be persistent. Our results support the view that indigenous knowledge must be acknowledged as process, emphasizing ways of observing, discussing, and interpreting new information. In this case, indigenous knowledge can help address complex relationships between phenomena, and help design adaptation strategies based on experimentation and knowledge coproduction.

    This study analyzed the epidemiological profile of pulmonary tuberculosis from 2007 to 2010 in municipalities (counties) in Mato Grosso do Sul State, Brazil, that border on Paraguay and Bolivia. In the border region, the incidence rate (49.1/100,000 inhabitants), mortality rate (4.0/100,000 inhabitants), and treatment dropout rate (11.3%) were 1.6, 1.8, and 1.5 times higher than in the non-border region. Among indigenous individuals in the border region, the rates for incidence (253.4/100,000 inhabitants), mortality (11.6/100,000 inhabitants), and HIV/TB co-infection (1.9/100,000 inhabitants) were 6.4, 3.2, and 1.9 times higher than in non-indigenous individuals in this region. Living in the border regions was inversely associated with HIV/TB co-infection. Indigenous ethnicity was associated statistically with not abandoning TB treatment. The study concludes that the population residing in these municipalities along the border is exposed to high risk of pulmonary TB and TB mortality and treatment dropout, thus requiring special health surveillance interventions.

    Full Text Available Community-based management research is a collaborative effort between management, academics and communities in need with the specific goal of achieving social change to foster social justice. Because it is designed to promote and validate joint methods of discovery and community-based sources of knowledge, community-based management research has several unique characteristics, which may affect its execution. This article describes the process of a community-based management research project which is descriptive in nature and uses quantitative techniques to examine school efficiencies in low-income communities in a developing country – Bolivia. The article describes the partnership between a US-based university and a Bolivian not-for-profit organisation, the research context and the history of the research project, including its various phases. It focuses on the (yet unpublished process of the community-based research as opposed to its content (which has been published elsewhere. The article also makes the case that the robust partnership between the US-based university and the Bolivian NGO has been a determining factor in achieving positive results. Strengths and limitations are examined in the hope that the experience may be helpful to others conducting descriptive quantitative management research using community-engaged frameworks in cross-cultural settings. Keywords: international partnership, community-engaged scholarship, education efficiency, multicultural low-income education.

    Full Text Available La última década ha estado marcada por el resurgimiento de movimientos políticos izquierdistas en Latinoamérica. Sin embargo, la magnitud del alzamiento de estas “nuevas izquierdas” oculta a menudo la relación ambivalente entre estos movimientos y la sociedad, así como su lucha por encontrar alternativas al modelo de desarrollo prevaleciente. A lo largo del continente, el sector de las microfinanzas ha llenado el vacío dejado por los fallos de los bancos públicos, desarrollándose bajo una forma crecientemente comercial. Análisis de Nicaragua, Ecuador y Bolivia revelan que los nuevos gobiernos comparten su desconfianza hacia las IMF (instituciones de microfinanzas. Sin embargo, en la ausencia de alternativas viables para la provisión de servicios financieros, los gobiernos y las microfinanzas se ven obligados a coexistir. El medio en el cual lo hacen varía grandemente, dependiendo de políticas locales y factores institucionales. No obstante, algunas tendencias comunes pueden ser discernidas.

    Full Text Available In this study we compared the utility of two molecular biology techniques, cloning of the mitochondrial 12S ribosomal RNA gene and hydrolysis probe-based qPCR, to identify blood meal sources of sylvatic Chagas disease insect vectors collected with live-bait mouse traps (also known as Noireau traps. Fourteen T. guasayana were collected from six georeferenced trap locations in the Andean highlands of the department of Chuquisaca, Bolivia.We detected four blood meals sources with the cloning assay: seven samples were positive for human (Homo sapiens, five for chicken (Gallus gallus and unicolored blackbird (Agelasticus cyanopus, and one for opossum (Monodelphis domestica. Using the qPCR assay we detected chicken (13 vectors, and human (14 vectors blood meals as well as an additional blood meal source, Canis sp. (4 vectors.We show that cloning of 12S PCR products, which avoids bias associated with developing primers based on a priori knowledge, detected blood meal sources not previously considered and that species-specific qPCR is more sensitive. All samples identified as positive for a specific blood meal source by the cloning assay were also positive by qPCR. However, not all samples positive by qPCR were positive by cloning. We show the power of combining the cloning assay with the highly sensitive hydrolysis probe-based qPCR assay provides a more complete picture of blood meal sources for insect disease vectors.

  5. Differences in influence patterns between groups predicting the adoption of a solar disinfection technology for drinking water in Bolivia.

    The lack of safe drinking water is one of the major problems faced by developing countries. The consequences of contaminated water are diseases such as diarrhea, one of the main causes of infant mortality. Because of its simplicity, solar water-disinfection technology provides a good way of treating water at the household level. Despite its obvious advantages and considerable promotional activities, this innovation has had rather a slow uptake. We conducted a field survey in which 644 households in Bolivia were interviewed in order to gain insights on motivations that resulted in adopting the technology. The aim was to examine possible differences in the predictors for adopting this technology during the diffusion process using the theory of innovation diffusion. Our findings indicate that early adoption was predicted by increased involvement in the topic of drinking water and that adoption in the middle of the diffusion process was predicted by increased involvement by opinion leaders and by recognition of a majority who supported the technology. Finally, late adoption was predicted by recognition that a majority had already adopted. Suggestions for future promotional strategies are outlined. PMID:18508169

    This report documents primate communities at two sites within Noel Kempff Mercado National Park in northeastern Santa Cruz Department, Bolivia. Diurnal line transects and incidental observations were employed to survey two field sites, Lago Caiman and Las Gamas, providing information on primate diversity, habitat preferences, relative abundance, and population density. Primate diversity at both sites was not particularly high, with six observed species: Callithrix argentata melanura, Aotus azarae, Cebus apella, Alouatta caraya, A. seniculus, and Ateles paniscus chamek. Cebus showed no significant habitat preferences at Lago Caiman and was also more generalist in use of forest strata, whereas Ateles clearly preferred the upper levels of structurally tall forest. Callithrix argentata melanura was rarely encountered during surveys at Lago Caiman, where it preferred low vine forest. Both species of Alouatta showed restricted habitat use and were sympatric in Igapo forest in the Lago Caiman area. The most abundant primate at both field sites was Ateles, with density estimates reaching 32.1 individuals/km2 in the lowland forest at Lago Caiman, compared to 14.1 individuals/km2 for Cebus. Both Ateles and Cebus were absent from smaller patches of gallery forest at Las Gamas. These densities are compared with estimates from other Neotropical sites. The diversity of habitats and their different floristic composition may account for the numerical dominance of Ateles within the primate communities at both sites. PMID:9802511

    Neo-institutional economics (NEI) has long shown that take-or-pay (ToP) long-term contracts provide a robust framework for safeguarding the interests of both upstream and downstream parties in the gas industry. The case of gas trade between Brazil and Bolivia presents an opportunity to re-examine empirically and to review the robust nature of the ToP framework over time. This case reveals that the positions of the contractors actually change giving rise to a veritable lifecycle of the contractual arrangement. Such a contract can be seen to span three successive phases. The first phase of the contract cycle begins when it is signed; allowing the investments to begin. The second phase starts when investments have been completed and the actual trade in gas begins. The third phase of the contract cycle comes when the increasing flow of gas comes close to saturating capacity and the volume levels for downstream market volume have been reached. These three contract phases are thus distinguished by how robust the alignment of the parties' interests is. The added value of the paper is then both empirical and analytical: the case study provides a brand new lifecycle analysis of the performance of ToP long-term contracting into an NEI framework.

  15. Social differentiation and embodied dispositions: a qualitative study of maternal care-seeking behaviour for near-miss morbidity in Bolivia

    Directory of Open Access Journals (Sweden)

    Liljestrand Jerker

    2009-07-01

    Full Text Available Abstract Background Use of maternal health care in low-income countries has been associated with several socioeconomic and demographic factors, although contextual analyses of the latter have been few. A previous study showed that 75% of women with severe obstetric morbidity (near-miss identified at hospitals in La Paz, Bolivia were in critical conditions upon arrival, underscoring the significance of pre-hospital barriers also in this setting with free and accessible maternal health care. The present study explores how health care-seeking behaviour for near-miss morbidity is conditioned in La Paz, Bolivia. Methods Thematic interviews with 30 women with a near-miss event upon arrival at hospital. Near-miss was defined based on clinical and management criteria. Modified analytic induction was applied in the analysis that was further influenced by theoretical views that care-seeking behaviour is formed by predisposing characteristics, enabling factors, and perceived need, as well as by socially shaped habitual behaviours. Results The self-perception of being fundamentally separated from "others", meaning those who utilise health care, was typical for women who customarily delivered at home and who delayed seeking medical assistance for obstetric emergencies. Other explanations given by these women were distrust of authority, mistreatment by staff, such as not being kept informed about their condition or the course of their treatment, all of which reinforced their dissociation from the health-care system. Conclusion The findings illustrate health care-seeking behaviour as a practise that is substantially conditioned by social differentiation. Social marginalization and the role health institutions play in shaping care-seeking behaviour have been de-emphasised by focusing solely on endogenous cultural factors in Bolivia.

    Full Text Available RESUMEN: El artículo analiza cómo el papel de los medios masivos de comunicación en la política contemporánea de las sociedades latinoamericanas empieza a adquirir mayor relevancia en los últimos años, tanto en el ámbito académico como en el ámbito político. Presenta algunas reflexiones acerca de los nuevos roles que están asumiendo los medios de comunicación masiva y el nuevo lugar que éstos están pugnando dentro del espacio público en un contexto de crisis de las tradicionales instancias dotadoras de sentido.Los medios masivos devienen como instancias públicas de interpelación, de mediación, de constitución de identidades y de construcción de ciudadanos. Esto será ilustrado con un estudio de caso en Bolivia: el Sistema de "Radio y Televisión Popular" (RTP y su programa "La Tribuna Libre del Pueblo" (TLP, a partir de los cuales emerge un sujeto social, que adquiere visibilidad cuando irrumpe como movimiento social (Palenquismo y, que luego se constituye en un actor político destacado a nivel nacional cuando se institucionaliza en el partido político Conciencia de Patria (CONDEPA.RTP y la TLP al dar acceso al micrófono a amplios sectores populares hacen posible que su "voz" sea escuchada y amplificada, hacia sus semejantes como hacia el resto de la sociedad. Con esto contribuye a que dichos sujetos puedan "expresarse", "mirarse" y "oirse" a través de las ondas de radio o la pantalla catódica, con lo cual contribuye a que se reconozcan como "cholos, "indios", "compadres" y "hermanos dentro de la gran familia RTP", y constituyan una comunidad de sentido, una identidad colectiva. Y lo más importante, es que estos medios masivos han coadyuvado a que ciertos individuos que inicialmente se reconocían solamente como sujetos con necesidades y deberes, hayan pasado a reconocerse como "sujetos con derechos" en una sociedad que los ha excluido permanentemente.ABSTRACT: This paper analizes the role of mass media in contemporary

    Palynological and Rock-Eval pyrolysis studies of the Chaunaca and El Molino Fm (Santonian to Thanetian, Cordillera Oriental, Bolivia) indicate that some facies have economic significance as potential oil source rocks. The occurrence of Pediastrum and Azolla testify a lacustrine environment. In the Upper Molino, the environmental interpretation of an almost monospecific association of dinocysts is discussed. The presence of Apectodinium quinquelatum indicates that the age of the upper part of the Upper El Molino Fm is likely to be Upper Thanetian. (authors). 22 refs., 5 figs.

    The purpose of this paper is to use climatic history for contributing to the general objectives of the IAI -CRN II-047 Project. It will reconstruct, from archival documents, the hydroclimatic variability occurring in the high basin of the Bermejo River during the last centuries and its effects on the floods and swellings in the middle basin. The Río Bermejo in the Southern Andes, is a binational (Argentina-Bolivia) river that contributes the largest proportion of the sediment load to the La Plata basin. Its headwaters are in the Subtropical Andes, near Tarija, Bolivia (22?00'14"S, 64?57'38"W). The main headwater tributaries are the Río Grande de Tarija, in Bolivia and the Iruya and San Francisco Rivers in Argentina. When the river abandons the mountain and turns eastwards (Gran Chaco), it acquires the characteristics of typical lowland rivers, widens its course, and occupies a large, low sedimentary plain with vast floodland areas. Quite often during very high sediment discharge the main river avulses and changes its course, creating big alluvial plains that are occupied for many years. Administrative documents from the colonial and republican periods have provided useful information to reconstruct climate and hydrology of the region. Documents from the Archivo General de Indias in Seville, Archivo Nacional de Bolivia and Archivo General de la Nación (Argentina) have been used to identify extreme floods and swellings in the high and middle-basin of the Rio Bermejo from the 17th century to the first decades of the 20th century. Old maps of the region, reports from annals, chronicles, priests' and travelers' descriptions were also used. Diaries written by the military, explorers and government officials in charge of discovering and taking possession of the territory also provide important sources of information. The archival documents show abrupt hydrological changes in response to the climatic fluctuations in the headwaters region. These records document

    Habitat structure and anthropogenic disturbance are known to affect primate diversity and abundance. However, researchers have focused on lowland rain forests, whereas endangered deciduous forests have been neglected. We aimed to investigate the relationships between primate diversity and abundance and habitat parameters in 10 deciduous forest fragments southeast of Santa Cruz, Bolivia. We obtained primate data via line-transect surveys and visual and acoustic observations. In addition, we assessed the vegetation structure (canopy height, understory density), size, isolation time, and surrounding forest area of the fragments. We interpreted our results in the context of the historical distribution data for primates in the area before fragmentation and interviews with local people. We detected 5 of the 8 historically observed primate species: Alouatta caraya, Aotus azarae boliviensis, Callithrix melanura, Callicebus donacophilus, and Cebus libidinosus juruanus. Total species number and detection rates decreased with understory density. Detection rates also negatively correlated with forest areas in the surroundings of a fragment, which may be due to variables not assessed, i.e., fragment shape, distance to nearest town. Observations for Alouatta and Aotus were too few to conduct further statistics. Cebus and Callicebus were present in 90% and 70% of the sites, respectively, and their density did not correlate with any of the habitat variables assessed, signaling high ecological plasticity and adaptability to anthropogenic impact in these species. Detections of Callithrix were higher in areas with low forest strata. Our study provides baseline data for future fragmentation studies in Neotropical dry deciduous forests and sets a base for specific conservation measures.

The NGO Adventist Development and Relief Agency (ADRA is implementing a malaria project with community health workers (CHW, who provide diagnosis and treatment.Material and MethodsA total of 160 CHW were involved in the Implementation of diagnosis and treatment. The present study was undertaken in two stages in 2011 and 2012, evaluating 44 and 102 CHW respectively.ResultsThe average age of the CHW was 37 years and 32% were women. In 2011 and 2012, 87% and 92%, respectively, of CHW had support material available, while 96% and 93%, respectively, knew basic information about malaria. During the monitoring of performance of the rapid malaria test, 50% of CHW did not check the expiration period, 28% did not record the name of the patient, 18% did not adequately collect blood with the pipette, 18% read the result before the required time had elapsed, 25% did not record the result in the form, 40% did not dispose of the used material, and 16% did not report the result. Regarding treatment for children, there was an increase in the coverage of treatment from 64% to 84% for P. vivax cases, and from 66% to 75% for P. falciparum cases. For adults, there was an increase in coverage from 89% to 93% for P. falciparum cases.DiscussionThe CHW must improve regarding the following aspects: filling in the malaria registration form; carrying out the rapid test; and providing the correct treatment dosage. Therefore, continued monitoring of their implementation of the project is essential.

    Full Text Available BACKGROUND: Chagas disease, caused by the flagellate parasite Trypanosoma cruzi affects 8-10 million people in Latin America. The mechanisms that underlie the development of complications of chronic Chagas disease, characterized primarily by pathology of the heart and digestive system, are not currently understood. To identify possible host genetic factors that may influence the clinical course of Chagas disease, Human Leucocyte Antigen (HLA regional gene polymorphism was analyzed in patients presenting with differing clinical symptoms. METHODOLOGY: Two hundred and twenty nine chronic Chagas disease patients in Santa Cruz, Bolivia, were examined by serological tests, electrocardiogram (ECG, and Barium enema colon X-ray. 31.4% of the examinees showed ECG alterations, 15.7% megacolon and 58.1% showed neither of them. A further 62 seropositive megacolon patients who had undergone colonectomy due to acute abdomen were recruited. We analyzed their HLA genetic polymorphisms (HLA-A, HLA-B, MICA, MICB, DRB1 and TNF-alpha promoter region mainly through Sequence based and LABType SSO typing test using LUMINEX Technology. PRINCIPAL FINDINGS: The frequencies of HLA-DRB1*01 and HLA-B*14:02 were significantly lower in patients suffering from megacolon as well as in those with ECG alteration and/or megacolon compared with a group of patients with indeterminate symptoms. The DRB1*0102, B*1402 and MICA*011 alleles were in strong Linkage Disequilibrium (LD, and the HLA-DRB1*01-B*14-MICA*011 haplotype was associated with resistance against chronic Chagas disease. CONCLUSIONS: This is the first report of HLA haplotype association with resistance to chronic Chagas disease.

  17. Evaluation of particle dispersal from mining and milling operations using lead isotopic fingerprinting techniques, Rio Pilcomayo Basin, Bolivia

    International Nuclear Information System (INIS)

    Mining and milling of ores from the Cerro Rico de Potosi precious metal-polymetallic tin deposits of Bolivia have led to severe contamination of water and sediments of the Rio Pilcomayo drainage system. Lead (Pb) isotopic data were used in this study to first document downstream dispersal patterns of Pb contaminated sediment within the channel of the Rio Pilcomayo, and then to determine the relative contribution of Pb from Cerro Rico within alluvial terrace soils that are used for agriculture. The concentration and isotopic composition of Pb within channel bed sediments differed significantly between 2000, 2002, and 2004. These differences presumably reflect changes in the type of ore mined and milled at Cerro Rico, and alterations in dispersal and grain-size dilution mechanisms associated with interannual variations in rainfall and runoff. Within agricultural terrace soils, both Pb concentrations and the percentage of Pb from Cerro Rico: (1) semi-systematically decrease downstream, (2) were found to decrease with terrace height above the channel, and (3) reflect the use of contaminated irrigation water. In upstream reaches (within 30 km of the mills), Pb from mining represents the most significant Pb source, accounting for more than 80% of Pb in the examined agricultural fields. At Sotomayor, located approximately 170 km from the mills, the relative contribution of Pb from Cerro Rico is highly variable between fields, but can be significant, ranging from approximately 15% to 35%. The analysis demonstrates that Pb isotopic ratios can be used to effectively trace contaminated particles through river systems and into adjacent alluvial soils, even where multiple Pb sources exist and Pb concentrations are similar to background values

    This paper introduces the administration system of mining industry in Bolivia. The system has the common characteristics with South American countries;and they have divided the mining activities into basic mining activities and mining auxiliary activities, which have been subject to different laws. At the same time, national mining companies have directly involved in mining management which epitomized the nationalism over mineral resources. In terms of mineral right, there is no mineral exploration right or exploitation right in Bolivia.%  玻利维亚矿业管制体制具有南美国家共同的特点,将矿业活动分为基础矿业活动与矿业辅助活动,并适用不同的法律,同时国家矿业公司直接参与矿业管理,是矿产资源民族主义的集中体现。玻利维亚矿业权没有探矿权、采矿权之分,是其有别于大多数国家的重要特点。相对于其矿业开发环境保护的相关规定,玻利维亚矿业税费总体上比较简单,集中体现在矿业权特许费上。

    Accurate estimates of global carbon emissions are critical for understanding global warming. This paper estimates net carbon emissions from land use change in Bolivia during the periods 1990-2000 and 2000-2010 using a model that takes into account deforestation, forest degradation, forest regrowth, gradual carbon decomposition and accumulation, as well as heterogeneity in both above ground and below ground carbon contents at the 10 by 10 km grid level. The approach permits detailed maps of net emissions by region and type of land cover. We estimate that net CO2 emissions from land use change in Bolivia increased from about 65 million tons per year during 1990-2000 to about 93 million tons per year during 2000-2010, while CO2 emissions per capita and per unit of GDP have remained fairly stable over the sample period. If we allow for estimated biomass increases in mature forests, net CO2 emissions drop to close to zero. Finally, we find these results are robust to alternative methods of calculating emissions.

    The Bolivia-Brazil Natural Gas Pipeline is approximately 3,500 kilometers long since the city of Rio Grande, in Bolivia, until the city of Canoas, in the South of Brazil. The south spread of the pipeline - approximately 850 kilometers long - is characterized by a steep topography combined with a variety of geological sites, such as colluviums deposits and debris flow areas. Within such a scenario, a spot nearby Curriola River, as can be seen in Figure 1.a, it shows hillsides with slopes of almost 40 degrees of inclination. Every year, mainly along the rainy season, mass movements tend to overburden the pipeline, jeopardizing its integrity. Because of this, geotechnical works have been done and, since 2004 up to 2008, mechanical stress surveys were applied. This paper aims to summarize all mechanical investigations made, including residual stresses assessment, the variation of the state of mechanical stresses along those years, methodology and full interpretation of the data acquired. From this gross data, internal pressure loading and residual stresses have been discounted from the combined stresses assessed, so as to indicate only the ground interaction and main direction of the corresponding loading. All this together with geotechnical models is intended to support mitigation measures for global stress relieving and preserving the pipeline's integrity. (author)

  1. Evaluation of agricultural reuse practices and relevant guidelines for the alba rancho WWTP (primary and secondary facultative ponds) in Cochabamba, Bolivia.

    Many cities in developing countries are experiencing high population growth, which is generating chaotic and unplanned development, reducing land areas available for agriculture, and polluting surface and groundwater. Consequently, the reuse of untreated or partially treated wastewater for agricultural irrigation is increasing in arid and semi-arid regions in developing countries. Cochabamba city in Bolivia also has a high population growth. The climatic characteristics and the lack of clean water sources in this city are forcing the agriculture sector to use treated and untreated wastewater for irrigation. We investigated the effluent quality of the Alba Rancho Wastewater Treatment Plant (WWTP) in Cochabamba, Bolivia, and the existing effluent reuse practices for irrigation of fodder crops in the surrounding agricultural land (La Mayca area). The plant uses primary and secondary facultative ponds, and does not achieve the required effluent quality (according to Bolivian environmental law) for effluent BOD, COD, TDS and faecal coliforms. This paper also includes a brief comparison of guidelines for wastewater reuse in agriculture from several developing and developed countries, comparing the parameters measured as pollution indicators. It appears that for developed countries, the main concern is the health risk that reuse can cause to the farmers and consumers. For developing countries on the other hand, pollution reduction is currently the major aim in their guidelines and standards. PMID:17305172

  2. Socialist government health policy reforms in Bolivia and Ecuador: The underrated potential of integrated care to tackle the social determinants of health

    2009-12-01

    Full Text Available Background Selective vertical programs prevailed over comprehensive primary health care in Latin America. In Bolivia and Ecuador, socialist governments intend to redirect health policy. We outline both countries’ health system’s features after reform, explore their efforts to rebuild primary health care, identify and explain policy gaps, and offer considerations for improvement. Methods Qualitative document analysis. Findings Earlier reform left Bolivia’s and Ecuador’s population in bad health, with limited access to a fragmented health system. Today, both countries focus their policy on household and community-based promotion and prevention. The negative effects on access to care of decentralization, dual employment, vertical programming and targeting are largely left unattended. Neglecting care is understandable in the light of particular interpretations of social medicine and social determinants, international policy pressures, reliance on external funding and institutional inertia. Current policy choices preserve key elements of selective care and consolidate commodification. It might not improve health and worsen poverty. Interpretation Care can be considered as a social determinant on its own. Key to the accomplishment of primary care is an integrated application of family medicine, taking advantage of individual care as one of the ways to act on social determinants. It deserves a central place on the policy-makers’ priority list, in Bolivia and Ecuador as elsewhere.

    In South America, cutaneous leishmaniasis is the most frequent clinical form of leishmaniasis. Bolivia is one of the countries with higher incidence, with 33 cases per 100,000 individuals, and the disease is endemic in 70% of the territory. In the last decade, the number of cases has increased, the age range has expanded, affecting children under 5 years old, and a similar frequency between men and women is found. An entomological study with CDC light traps was conducted in three localities (Chipiriri, Santa Elena and Pedro Domingo Murillo) of the municipality of Villa Tunari, one of the main towns in the Chapare province (Department of Cochabamba, Bolivia). A total of 16 specimens belonging to 6 species of the genus Lutzomyia were captured: Lu. aragaoi, Lu. andersoni, Lu. antunesi, Lu. shawi, Lu. yuilli yuilli and Lu. auraensis. Our results showed the presence of two incriminated vectors of leishmaniasis in an urbanized area and in the intradomicile. More entomological studies are required in the Chapare province to confirm the role of vector sand flies, the intradomiciliary transmission of the disease and the presence of autochthonous cases of cutaneous leishmaniasis.

The study’s main contributions to the literature are that government coalitions based more on strategic issues than on programmatic ones are fertile ground for policy switches, and it is possible that their secondary effects will be perceived more in the long run than in the short term.

  5. PCR reveals significantly higher rates of Trypanosoma cruzi infection than microscopy in the Chagas vector, Triatoma infestans: High rates found in Chuquisaca, Bolivia

    Full Text Available Abstract Background The Andean valleys of Bolivia are the only reported location of sylvatic Triatoma infestans, the main vector of Chagas disease in this country, and the high human prevalence of Trypanosoma cruzi infection in this region is hypothesized to result from the ability of vectors to persist in domestic, peri-domestic, and sylvatic environments. Determination of the rate of Trypanosoma infection in its triatomine vectors is an important element in programs directed at reducing human infections. Traditionally, T. cruzi has been detected in insect vectors by direct microscopic examination of extruded feces, or dissection and analysis of the entire bug. Although this technique has proven to be useful, several drawbacks related to its sensitivity especially in the case of small instars and applicability to large numbers of insects and dead specimens have motivated researchers to look for a molecular assay based on the polymerase chain reaction (PCR as an alternative for parasitic detection of T. cruzi infection in vectors. In the work presented here, we have compared a PCR assay and direct microscopic observation for diagnosis of T. cruzi infection in T. infestans collected in the field from five localities and four habitats in Chuquisaca, Bolivia. The efficacy of the methods was compared across nymphal stages, localities and habitats. Methods We examined 152 nymph and adult T. infestans collected from rural areas in the department of Chuquisaca, Bolivia. For microscopic observation, a few drops of rectal content obtained by abdominal extrusion were diluted with saline solution and compressed between a slide and a cover slip. The presence of motile parasites in 50 microscopic fields was registered using 400× magnification. For the molecular analysis, dissection of the posterior part of the abdomen of each insect followed by DNA extraction and PCR amplification was performed using the TCZ1 (5' – CGA GCT CTT GCC CAC ACG GGT GCT – 3

    Full Text Available Abstract: Challenges and perspectives of water governance and integrated water resource management in BoliviaBolivia is not only highly affected by social and political instability, but also by erosion and climate change and an indiscriminate and vast exploitation of its natural resources. The new policy structure seeks to establish a broad consensus on better water governance relying on a participatory democracy approach and the commitment to indicators for sustainable development. The creation of a Water Ministry in 2006, which emerged from the water riots against privatization of water rights and sanitation services in 2000, can be interpreted as a clear sign for more integration of social movements and civil organizations. But at the present these organizations seemed to be marginalized from the decision-making process, and government and public institutions are confronting a complex situation of weakened legitimacy. The present paper offers an insight on the ongoing process, including the challenges and obstacles for the implementation of a new water policy and local integrated water management systems. The reflections consider the official legal framework and a policy analysis in order to illustrate the conflictive schemes in different regions and localities. The final aim is to indicate the gaps between the official discourse and local realities for water governance and to indicate some recommendations for a more coherent public-civic action in water governance, control and transparency. Resumen:Bolivia no solo es afectada por una inestabilidad social y política, sino también por erosión, efectos del cambio climático y una explotación indiscriminada de los recursos naturales. La nueva política de cambio social se propone, entre otros objetivos, lograr un consenso amplio de gobernanza en el agua, basado en un proceso democrático participativo y el compromiso de cumplir indicadores de desarrollo sostenible.

    Background Solar drinking water disinfection (SODIS) is a low-cost, point-of-use water purification method that has been disseminated globally. Laboratory studies suggest that SODIS is highly efficacious in inactivating waterborne pathogens. Previous field studies provided limited evidence for its effectiveness in reducing diarrhoea. Methods and Findings We conducted a cluster-randomized controlled trial in 22 rural communities in Bolivia to evaluate the effect of SODIS in reducing diarrhoea among children under the age of 5 y. A local nongovernmental organisation conducted a standardised interactive SODIS-promotion campaign in 11 communities targeting households, communities, and primary schools. Mothers completed a daily child health diary for 1 y. Within the intervention arm 225 households (376 children) were trained to expose water-filled polyethyleneteraphtalate bottles to sunlight. Eleven communities (200 households, 349 children) served as a control. We recorded 166,971 person-days of observation during the trial representing 79.9% and 78.9% of the total possible person-days of child observation in intervention and control arms, respectively. Mean compliance with SODIS was 32.1%. The reported incidence rate of gastrointestinal illness in children in the intervention arm was 3.6 compared to 4.3 episodes/year at risk in the control arm. The relative rate of diarrhoea adjusted for intracluster correlation was 0.81 (95% confidence interval 0.59–1.12). The median length of diarrhoea was 3 d in both groups. Conclusions Despite an extensive SODIS promotion campaign we found only moderate compliance with the intervention and no strong evidence for a substantive reduction in diarrhoea among children. These results suggest that there is a need for better evidence of how the well-established laboratory efficacy of this home-based water treatment method translates into field effectiveness under various cultural settings and intervention intensities.

    Full Text Available This article presents a reflection on the role of the school in constructing citizenship and the mechanisms employed to this end. Based on ethnographic research in two schools, and in the framework of the Educational Revolution, I underline paradoxes and contradictions that indicate both processes of discrimination and processes of reification in students who self-identify as «Aymara». Parades and Wiphalas (the Indigenous Peoples’ flag and new national emblem since 2009 have become symbols of the schools and form the backbone of the behaviors and values that the school institution seeks to transmit to its students. Family expectations, often left aside, are woven into the reasoning in order to highlight the complex relationship between what is familiar and what is foreign, as well as challenges to interculturality, understood as a tool for emancipation.Este artículo presenta una reflexión sobre el papel de la escuela en la construcción de ciudadanía y los mecanismos empleados para tal fin. A partir de una investigación etnográfica en dos escuelas, y en el marco de la «Revolución Educativa» en Bolivia, subrayo paradojas y contradicciones que apuntan a procesos tanto de discriminación como de reificación de los estudiantes (autoidentificados como «aymara». Desfiles y wiphalas (bandera de los pueblos originarios y emblema nacional desde 2009 se erigen, respectivamente, como símbolo de cada una de las escuelas y vertebran las conductas y valores que la institución escolar pretende transmitir a sus estudiantes. Las expectativas familiares, tantas veces obviadas, se entretejen en el argumento para poner de relieve la compleja relación entre «lo propio» y «lo ajeno» así como los desafíos a los que se enfrenta la interculturalidad entendida como herramienta de emancipación.

    Two arrays of broad-band seismic stations were deployed in the north central Andes between 8° and 21°S, the CAUGHT array over the normally subducting slab in northwestern Bolivia and southern Peru, and the PULSE array over the southern part of the Peruvian flat slab where the Nazca Ridge is subducting under South America. We apply finite frequency teleseismic P- and S-wave tomography to data from these arrays to investigate the subducting Nazca plate and the surrounding mantle in this region where the subduction angle changes from flat north of 14°S to normally dipping in the south. We present new constraints on the location and geometry of the Nazca slab under southern Peru and northwestern Bolivia from 95 to 660 km depth. Our tomographic images show that the Peruvian flat slab extends further inland than previously proposed along the projection of the Nazca Ridge. Once the slab re-steepens inboard of the flat slab region, the Nazca slab dips very steeply (˜70°) from about 150 km depth to 410 km depth. Below this the slab thickens and deforms in the mantle transition zone. We tentatively propose a ridge-parallel slab tear along the north edge of the Nazca Ridge between 130 and 350 km depth based on the offset between the slab anomaly north of the ridge and the location of the re-steepened Nazca slab inboard of the flat slab region, although additional work is needed to confirm the existence of this feature. The subslab mantle directly below the inboard projection of the Nazca Ridge is characterized by a prominent low-velocity anomaly. South of the Peruvian flat slab, fast anomalies are imaged in an area confined to the Eastern Cordillera and bounded to the east by well-resolved low-velocity anomalies. These low-velocity anomalies at depths greater than 100 km suggest that thick mantle lithosphere associated with underthrusting of cratonic crust from the east is not present. In northwestern Bolivia a vertically elongated fast anomaly under the Subandean Zone

    There are close to 1 million people in the world who are alive simply because they have access to one form or another of renal replacement therapy (RRT). Ninety percent live in high-income countries. Little is known of prevalence and incidence of chronic kidney disease and of end-stage renal disease (ESRD) in middle-income and low-income countries, where the use of RRT is scarce or nonexistent. However, no intervention is undertaken, these people will experience progression to ESRD and death from uremia, because RRT is out of reach for them. These are the individuals for whom efforts should be focused to prevent or delay progression toward ESRD. In 1992, the Mario Negri Institute for Pharmacological Research in Bergamo, Italy, with the cooperation of the young doctors of the Ospedale Giovanni XXIII in La Paz (Bolivia), activated a specific project titled "El Proyecto de Enfermedades Renales en Bolivia" (The Project for Renal Diseases in Bolivia). The project sought to demonstrate that in emerging countries the best strategies against renal disease are prevention and early detection. After proper training of local personnel at the Clinical Research Center "Aldo e Cele Dacco" of the Mario Negri Institute in Bergamo, Italy, an educational campaign titled "First Clinical and Epidemiological Program of Renal Diseases"-under the auspices of the Renal Sister Center Program of the International Society of Nephrology-was conducted in 3 selected areas of Bolivia, including tropical, valley, and plains areas. The goal was to define the frequency of asymptomatic renal disease in these areas by screening a large population of patients at relatively low costs. The screening was formally performed at first-level health centers (Unidad de Salud). Participants were instructed to void a clean urine specimen, and a dipstick test was performed. Patients with positive urinalysis were enrolled in a follow-up program with subsequent laboratory and clinical checks. The study was conducted

    The goal of this study was to identify the degree of knowledge of students and health educators on licit and illicit drugs, related to the type, classification, action, mechanisms damages, consequences and adverse effects, besides use and consumption. A cross-sectional methodological design was used, with a sample of 172 students, professors and residents in medicine and nursing at Universidad Mayor de San Andrés (UMSA), Bolivia. The results reveal weak knowledge on the classification of psychotropic substances according to structure, chemical property and effects for health, highlighting significant difference with knowledge on licit and illicit drugs use, with high percentages. In conclusion, there is lack of knowledge in all groups studied on licit and illicit drugs regarding the consequences and adverse effects. This confirms the need to improve teaching on this content in health schools.

    In Bolivia, the prevalence of infection by T. cruzi in women in fertile age can vary between 20 and 60%. The present study made in the Maternity Germin Urquidi of Cochabamba - Bolivia, it has demonstrated, that 19.9% of the mothers who go to this hospitable center to be taken care of in the childbirth, they are carrying of the infection and that 4,6% of them, they are going to transmit, by transplacentaria route, the infection to its babies. Of the 71 children born with congenital Chagas, only 47,8 % present/display some type of alteration or of development(Apgar to 1 minute low, BPN, prematuridad, pathological dismadurez) or signs (SDR, hepatomegalia, esplenomegalia, neurological signs, cardiomegalia, anasarca, petequias). When investigating the effect of the differences in the vectorial density (low, medium and high) of the zone of maternal residence, on the transmission of the infection of the mother infected to the fetus, we concluded that the rate of transmission of the congenital infection of T. cruzi is not modified by the level of endemicidad of the zone of maternal residence. By another infected new born sides whose mothers reside in zones of high endemicidad present/display, most frequently and of significant way, Apgar to 1 minute prematuridad or an association of these alterations with respiratory syndrome of distress or anasarca, when one compares them with new born of resident mothers in the zones of loss or medium endemicidad, mortality in this group is greater. These results suggest calls to account it of the mothers, in areas of high endemicidad, she is associate with a serious increase in the risk of Disease of newborn severe and mortal congenital Chagas in.

    Full Text Available Varias regiones bolivianas reclamaron en su discurso autonómico su marginación en relación al centralismo estatal asociado con La Paz. ¿Pero cuál es el centro dado que hasta la propia capital sufrió un traslado? A partir de una revisión de los presupuestos se analiza la proveniencia de los ingresos y su distribución entre las regiones. Dos son nuestros planteamientos: uno de orden metodológico, otro de orden historiográfico. A través del análisis histórico se plantea que occidente financió al Estado boliviano por lo menos hasta 1952 y que el desequilibrio regional de hoy es resultado de las políticas desplegadas en el siglo XX. En términos metodológicos planteamos una lectura social de los presupuestos porque en ellos se plasman las relaciones de larga y corta duración entre el Estado y las regiones y entre el Estado y diferentes actores sociales.A number of regions in Bolivia argued marginalization –associated with State centralism– as part of a demand for more autonomy. ¿But what exactly is the centre, given that the very capital has changed location? By studying the budgets, this article analyses the source of income and its regional distribution, offering methodological and historiographical observations. Through historical analysis, the article observes how, at least until 1952, Bolivia was funded by the West axis, and that the current regional inequality is a result of policies that were implemented in the XX century. Methodologically speaking, we advocate a social interpretation of the budgets given that this would effectively convey the short-term and long-term relationships between the State and the regions; and between the State and other social actors.

    The investigated area involves the Pipeline Row of Bolivia Mato-Grosso, inserted in the South-center of The Serrana Province (Almeida, 1964). The south-center section of Serrana Province is a water divisor from those that leaks west directly to Paraguay River from the waters that leaks on the east side to Pantanal. This work has as main subject, to diagnose and to value the environmental impacts that occurred and can occur in the future on the brooks and springs where there were Pipeline Bolivia Mato-Grosso interference on its crossing at the Serrana area, in Caceres municipality. The springs monitor were done during 18 months (march, 2001 to September, 2001), during and after the ending of the works, including different climates and hydrologic conditions, making it possible to diagnose and to value the draining behavior on the drought and on the overflow epoch. So, we believe that the knowledge about the interferences, risks and alterations that reflects on the fluvial duct of the sub-basin that drains the Serrana Province and leaks to Paraguay River may be contributing indirectly or directly to the Pantanal conservation.

    In Bolivia's western highlands, at an altitude of some 3,600 metres, lie the largest identified reserves of lithium in the world. According to the latest estimates by the United States Geological Survey (USGS), beneath the 10,000 square kilometres of what are the world's most extensive salt flats, the Salar de Uyuni, there are some 6 to 9 million tonnes of lithium (Roskill 2008 nach Angerer, Marscheider-Weidemann, Wendl et al. 2009, Jaskula 2010a). Exploitation of those reserves has not yet begun, though the Bolivian government has constructed a small 6 million US Dollar pilot plant on the edge of the Salar de Uyuni, and has some ambitious plans: ''Lithium is the hope not just for Bolivia but for all inhabitants of the planet'', stated Bolivia's President Evo Morales in February 2009 (Bajak/Valdez 2009). Bolivia is one of the poorest countries in Latin America. The production of lithium, and the revenues it can generate, represents a major development opportunity for the country. Lithium is a key constituent of lithium ion batteries. Already in widespread use in mobile phones, camcorders and laptops, they are also increasingly needed to power hybrid and electric vehicles, which is why many analysts regard lithium as one of the key raw materials in the move towards sustainable mobility in the post-oil era (National Research Council (U.S.) 2008, Angerer et al. 2009, Tahil 2007; Chameides 2009). As the demand for lithium rises and its importance grows, the question arises as to the risks and opportunities associated with it. The resource booms of the past did little to promote Bolivia's development and improve the standard of living of its population. Indeed, Bolivia has a long history of resource-related conflict and political instability. This report (3.3) therefore investigates the risks and opportunities associated with the establishment of industrial-scale lithium production in Bolivia. Its analysis follows on from reports

    Middle Proterozoic rocks underlying the Andes in western Bolivia, western Argentina, and northern Chile and Early Proterozoic rocks of the Arequipa massif in southern Peru?? from the Arequipa-Antofalla craton. These rocks are discontinuously exposed beneath Mesozoic and Cenozoic rocks, but abundant crystalline clasts in Tertiary sedimentary rocks in the western altiplano allow indirect samples of the craton. Near Berenguela, western Bolivia, the Oligocene and Miocene Mauri Formation contains boulders of granodiorite augen gneiss (1171??20 Ma and 1158??12 Ma; U-Pb zircon), quartzose gneiss and granofels that are inferred to have arkosic protoliths (1100 Ma source region; U-Pb zircon), quartzofeldspathic and mafic orthogneisses that have amphibolite- and granulite-facies metamorphic mineral assemblages (???1080 Ma metamorphism; U-Pb zircon), and undeformed granitic rocks of Phanerozoic(?) age. The Middle Proterozoic crystalline rocks from Berenguela and elsewhere in western Bolivia and from the Middle Proterozoic Bele??n Schist in northern Chile generally have present-day low 206Pb/204Pb ( 15.57), and elevated 208Pb/204Pb (37.2 to 50.7) indicative of high time-averaged Th/U values. The Middle Proterozoic rocks in general have higher presentday 206Pb/204Pb values than those of the Early Proterozoic rocks of the Arequipa massif (206Pb/204Pb between 16.1 and 17.1) but lower than rocks of the southern Arequipa-Antofalla craton (206Pb/204Pb> 18.5), a difference inferred to reflect Grenvillian granulite metamorphism. The Pb isotopic compositions for the various Proterozoic rocks lie on common Pb isotopic growth curves, implying that Pb incorporated in rocks composing the Arequipa-Antofalla craton was extracted from a similar evolving Pb isotopic reservoir. Evidently, the craton has been a coherent terrane since the Middle Proterozoic. Moreover, the Pb isotopic compositions for the Arequipa-Antofalla craton overlap those of the Amazon craton, thereby supporting a link

    Full Text Available BACKGROUND: Chagas disease (American trypanosomiasis is a zoonotic or anthropozoonotic disease caused by the parasite Trypanosoma cruzi. Predominantly affecting populations in poor areas of Latin America, medical care for this neglected disease is often lacking. Médecins Sans Frontières/Doctors Without Borders (MSF has provided diagnostic and treatment services for Chagas disease since 1999. This report describes 10 years of field experience in four MSF programs in Honduras, Guatemala, and Bolivia, focusing on feasibility protocols, safety of drug therapy, and treatment effectiveness. METHODOLOGY: From 1999 to 2008, MSF provided free diagnosis, etiological treatment, and follow-up care for patients <18 years of age seropositive for T. cruzi in Yoro, Honduras (1999-2002; Olopa, Guatemala (2003-2006; Entre Ríos, Bolivia (2002-2006; and Sucre, Bolivia (2005-2008. Essential program components guaranteeing feasibility of implementation were information, education, and communication (IEC at the community and family level; vector control; health staff training; screening and diagnosis; treatment and compliance, including family-based strategies for early detection of adverse events; and logistics. Chagas disease diagnosis was confirmed by testing blood samples using two different diagnostic tests. T. cruzi-positive patients were treated with benznidazole as first-line treatment, with appropriate counseling, consent, and active participation from parents or guardians for daily administration of the drug, early detection of adverse events, and treatment withdrawal, when necessary. Weekly follow-up was conducted, with adverse events recorded to assess drug safety. Evaluations of serological conversion were carried out to measure treatment effectiveness. Vector control, entomological surveillance, and health education activities were carried out in all projects with close interaction with national and regional programs. RESULTS: Total numbers of

    An assemblage of 33 fossil pollen and spores, recovered from the 3600-m high Pislepampa locality of E. W. Berry, Eastern Cordillera, Bolivia, adds considerably to our knowledge of three aspects of the region in late Neogene time: (1) the paleovegetation, (2) the paleoclimate, and (3) the paleoelevation of the Central Andes. The plant microfossils recognized are Isoetes, Lycopodium (three types), Cnemidaria, Cyathea (three types), Grammitis, Hymenophyllum, Pteris, trilete fern spores (two types), Danaea, monolete fern spores (four types), Podocarpus, Gramineae, Palmae, Ilex, cf. Oreopanax, Cavanillesia, cf. Pereskia, Compositae (three types), Ericaceae, Tetrorchidium, and unknowns (three types). The diversity of the Compositae suggest that this flora has a maximum age around the Miocene-Pliocene boundary, that is, 6-7 million years. All members of the paleocommunity presently grow in the bosque montano húmedo (cloud forest) along the eastern slope of the Central Andes of Bolivia, which occurs between MATs (mean annual temperatures) of ∼10° and 20°C. The Pislepampa flora probably represents the lower limits of this forest because the fossil leaves collected by Berry from the same locality all have entire margins, suggesting that the flora grew near the cloud forest-tropical forest transition. Presently, the lower limit of the cloud forest forest has MATs of ∼20°C, a mean annual precipitation between 1000 and 1500 mm, and that part containing most of the identified genera of fossil pollen is found at elevations ∼1200-1400 m. These conditions are thus inferred for the Pislepampa flora; however, because of the uncertainty of the magnitude of global climate change and of possible changes in the ecological range of plant genera, we estimate an error of at least ±1000 m for the paleoelevation estimate. When the total uplift is corrected for probable amounts of erosionally driven isostatic rebound, the paleoelevation estimate suggests that from one-third to one

    In early Paleozoic time the Peru-Bolivia Trough at the South American Gondwana margin accommodated large volumes of siliciclastic detritus of hitherto largely unknown provenance. A multi-method provenance study of framework components, heavy minerals and whole rock geochemistry of Ordovician to Devonian formations of southern Peru and northern Bolivia reveals the predominant contribution from upper crustal sources. Main heavy minerals include zircon, tourmaline, rutile, apatite, garnet, epidote, monazite, and titanite and are strongly biased diagenetically towards the stable phases. Electron microprobe single grain analysis of tourmaline and rutile indicate that detrital tourmalines were derived mainly from metasedimentary, and subordinately, from granitic sources. Cr/Nb ratios in rutiles point to a metamafic derivation for 20-40% of grains, the remainder originating in felsic lithologies. Zr in rutile thermometry indicates a provenance from relatively high-grade metamorphic rocks transformed at temperatures between 500 °C and 900 °C, with clusters at c. 600 °C, 700 °C and 800 °C. U-Pb geochronological analysis of rutiles was largely unsuccessful due to high concentrations of common Pb. Three ages could be obtained and fall between 525 and 545 Ma, probably linking this detritus to the hidden Neoproterozoic orogen in what are now Cordillera Oriental and Sierras Subandinas. The most notable feature of the whole rock geochemical data is a high Cr content in the majority of samples, which otherwise have a composition similar to weathered upper continental crust. The elevated Cr contents indicates that ophiolitic rocks were either exposed to erosion abundantly in the source areas or had previously supplied significant volumes of detritus to intermittent sediment storage systems now eroded into the studied sedimentary rocks. Potential source candidates include the Ordovician metamorphic Tapo Ultramafic Complex in the Cordillera Oriental of central Peru, and the

    Fernández Juárez, Gerardo

    2010-06-01

    Full Text Available The periodic exhumation and moving of dead bodies is a ritual of long history in the Central Andes, as revealed by “programs to extirpate idolatry” in the 16th and 17th centuries as well as ethnography on current All-Saints Day celebrations. Despite the open hostility of the Catholic Church toward “unorthodox” customs regarding the dead, remarkable instances of them can still be observed and studied at present, such as the socalled “Feast of the Ñatitas” which is held on every Sunday following All-Saints Day in the premises and church of “the General Cemetery” of La Paz. The current process of “ritual empowerment” of native peoples and social movements in Bolivia makes it all too clear the full significance of this feast as well as its commanding presence in ritual time and space against the policy of Catholic Church authorities in the country.

    La periódica exhumación y traslado de cadáveres constituye un comportamiento ritual de larga duración en los Andes Centrales, tal y como acreditan los “procesos de extirpación de idolatrías” de los siglos XVI y XVII, así como la etnografía contemporánea en relación con la festividad de Todos los Santos. A pesar de la actitud crítica y el celo de la Iglesia Católica contra este tipo de comportamientos ceremoniales “heterodoxos”, contamos con ejemplos especialmente elocuentes que continúan practicándose en la actualidad; es el caso de la llamada “Fiesta de las Ñatitas”, que corresponde al domingo siguiente a la del Primero de Noviembre y que se celebra en el camposanto y en el templo del Cementerio General de La Paz. El actual proceso de “empoderamiento ritual” de los pueblos originarios y los movimientos sociales en Bolivia hace resaltar el alcance significativo de esta fiesta y su éxito rotundo en tiempos de vivo conflicto con los responsables de la Iglesia Católica boliviana.

    Full Text Available Desde la Declaración de ministros de educación de países iberoamericanos en Santa Fe de Bogotá, 4-6 de noviembre de 1992, la descentralización educativa ha sido un tema recurrente de las reformas educativas en los países iberoamericanos, donde en algunos de ellos las experiencias de descentralización antecedieron a esta Declaración y en otros fueron posteriores. Las reformas educativas desarrolladas en los últimos años asociaron la descentralización educativa a la participación social y la mejora de la calidad educativa, entre otros temas. Este artículo aborda precisamente estos aspectos, interrogándose sobre qué tipo de descentralización estaría vigente en Bolivia, cuáles serían sus características en cuanto a la participación social y cómo estaría incidiendo en la calidad educativa. Se ha optado por un enfoque de análisis de las micropolíticas y de las prácticas sociales de los actores, apoyándose metodológicamente en dos estudios de caso: La Paz y Tarabuco (Bolivia. El artículo sugiere que tanto las políticas de descentralización educativa como los enfoques teóricos de análisis desde las ciencias sociales han avanzado poco en explicar el fenómeno de las relaciones sociales de poder a nivel local que afecta a la naturaleza de cualquier proceso de descentralización, porque en los poderes centrales del Estado persiste una hegemonía del enfoque gerencialista y una visión esencialmente burocrática de la educación.

    Implications of a new collection of lycophytes of the genera Haplostigma Seward and Paleostigma Kräusel and Dolianiti from southern Bolivia and northern Argentina are presented. Fragmented herbaceous stems of lycophytes preserved as compressions, impressions and casts come from the Middle and Late Devonian Pescado (Huamampampa), Los Monos and Iquiri formations at Mataral, Yesera, Angosto del Pescado and Balapuca. The interbedded shales and siltstones bearing the lycophytes were also examined for palynology. They yielded mostly terrestrial palynomorphs with Grandispora pseudoreticulata and other Eifelian to Givetian species and fewer microplanktonic species (i.e., acritarchs, prasinophytes, chitinozoans). At Yesera, diagnostic spores and elements of the microplankton suggest a Givetian-Frasnian up to early Famennian age for the Haplostigma beds. Moreover, presence of the same brachiopod taxon in the Haplostigma intervals at Yesera Dique (palynologically barren) and Yesera Centro supports their correlation. This new information supports terrestrial connections between these Bolivian and Argentine areas and other regions of South America in the Eifelian - Givetian Afrosouthamerican Subrealm, which extended up to the early Famennian.

    Full Text Available Biocultural heritage-based products, including regional specialty foods, are increasingly part of sustainable rural development strategies. While export-oriented biocultural products are often the most visible, we examine the role of campesino gastronomic heritage in the Central Valley of Tarija, Bolivia, as a case study of a local market-centered biocultural resource-based development strategy reflected in an alternative agri-food network. We develop a biocultural sustainability framework to examine this network from ecological, economic and sociocultural perspectives. Data are drawn from interviews (n = 77, surveys (n = 89 and participant observation, with primary and secondary producers of traditional and new products, as well as restaurant owners, market vendors and local consumers. We find that campesino biocultural heritage and the alternative agri-food network surrounding it represent an influential territorial project that underpins many household economies, particularly for women. We conclude that the relatively small investments by local governments to promote campesino gastronomic heritage are having positive ripple effects on small-scale producer livelihoods and on biocultural sustainability. We suggest that further support to increase market access and reduce other barriers to participation in alternative food networks will likely increase the options and benefits available to small-scale producers mobilising campesino gastronomic heritage within the local economy.

    Cutaneous and mucosal leishmaniasis, caused in South America by Leishmania braziliensis, is difficult to cure by chemotherapy (primarily pentavalent antimonials [Sb(V)]). Treatment failure does not correlate well with resistance in vitro, and the factors responsible for treatment failure in patients are not well understood. Many isolates of L. braziliensis (>25%) contain a double-stranded RNA virus named Leishmaniavirus 1 (LRV1), which has also been reported in Leishmania guyanensis, for which an association with increased pathology, metastasis, and parasite replication was found in murine models. Here we probed the relationship of LRV1 to drug treatment success and disease in 97 L. braziliensis-infected patients from Peru and Bolivia. In vitro cultures were established, parasites were typed as L. braziliensis, and the presence of LRV1 was determined by reverse transcription-polymerase chain reaction, followed by sequence analysis. LRV1 was associated significantly with an increased risk of treatment failure (odds ratio, 3.99; P = .04). There was no significant association with intrinsic Sb(V) resistance among parasites, suggesting that treatment failure arises from LRV1-mediated effects on host metabolism and/or parasite survival. The association of LRV1 with clinical drug treatment failure could serve to guide more-effective treatment of tegumentary disease caused by L. braziliensis.

    This paper summarized the results of comprehensive petro-mineralogical and geochemical (archeometrical) investigation of Inka Period ceramics excavated from Inka (A.D. 1438-1535) and Late Intermediate Period (A.D. 1000/1200-1438) sites of the Paria Basin (Dept. Oruro, Bolivia). Applying geological analytical techniques we observed a complex and important archaeological subject of the region and the era, the cultural-economic influence of the conquering Inkas in the provincial region of Paria appearing in the ceramic material. According to our results, continuity and changes of raw material utilization and pottery manufacturing techniques from the Late Intermediate to the Inka Period are characterized by analytical methods. The geological field survey provided efficient basis for the identification of utilized raw material sources. On the one hand, ceramic supply of both eras proved to be based almost entirely on local and near raw material sources. So, imperial handicraft applied local materials but with sophisticated imperial techniques in Paria. On the other hand, Inka Imperial and local-style vessels also show clear differences in their material which suggests that sources and techniques functioned already in the Late Intermediate Period subsisted even after the Inka conquest of the Paria Basin. Based on our geological investigations, pottery supply system of the Paria region proved to be rather complex during the Inka Period.

    Full Text Available At their most local, initiatives to reduce emissions from deforestation and degradation (REDD will depend on rural people to manage forest resources. Although the design of frameworks, mechanisms and arrangements, to implement REDD programs have received significant attention, it is not yet clear how REDD+ will function on the ground or how the participation of local populations will be assured. Community forest management (CFM could be an option under REDD+ depending on how it is negotiated, largely because of the expectation that CFM could reduce emissions from deforestation and degradation. Examining institutional factors in the emergence of successful CFM systems and local forest enterprises could provide valuable lessons for REDD planners. We examine cases of CFM development in Mexico, Brazil and Bolivia, to assess the role of multi-scaled governance institutions in their development. Comparing and contrasting advanced CFM systems to regions where it is still emerging, we will show how the establishment of a local organizational base for communal resource management is crucial.

    Full Text Available We report on the intra-Amazonian migration of a pair of Orinoco Geese (Neochen jubata from Manú National Park, Peru. The species is Critically Endangered in Peru, so a major aim of the study was to aid conservation planning by learning the wet season location of the country's last known breeding population. We captured a breeding pair on October 27, 2010, and fitted the birds with Microwave Telemetry, Inc. GPS/Argos satellite PTT's. The pair migrated ∼655 km from Manú National Park to the Llanos de Moxos, Bolivia (Dept. of Bení in a predominantly longitudinal migration, reaching their final destination on December 23, 2010. Major movements (>5 km per time period were almost exclusively at night and were undertaken with and without moonlight. Foraging areas used at stopovers in the Llanos de Moxos were remarkably limited, suggesting the importance of grazing lawns maintained by the geese and other herbivores, possibly including cattle. Orinoco Geese are resident in the Llanos de Moxos year-round, so the Manú geese represent a partial migration from the Bení region. We hypothesize that cavity nest limitation explains the partial migration of Orinoco Geese from the Llanos de Moxos.

  17. Market-Based Instruments for the Conservation of Underutilized Crops: In-Store Experimental Auction of Native Chili Products in Bolivia

    2014-11-01

    Full Text Available Native chilies (Capsicum spp. are currently underutilized in Bolivia, one of this crop’s centers of diversity. Fewer local farmers cultivate native chilies annually due to low market demand. Increasing its private use value can lead to the in-situ conservation of this crop. The objective of the paper is to evaluate the market acceptability of three native chili products: (a chili marmalade; (b chili cooking paste; and (c pickled chilies. Multi-product Becker-DeGroot-Marschak experimental auctions and hedonic tests were conducted with 337 participants in La Paz and Santa Cruz. Data were analyzed using seemingly unrelated regressions. Results suggest that consumers are willing to pay price premiums of about 25–50 percent. Biodiversity conservation and improvements in farmers’ quality of life statements would not have influence on first purchase decisions but rather on repurchase decisions and therefore on consumers’ product loyalty. This in turn could lead to sustainable agro-biodiversity conservation, centered on consumers’ purchase of these products over time.

    We assessed the prevalence of intestinal parasites among 268 2-12-year-old children living in rural areas, small villages, and semi-urban areas of the Chaco region, south-eastern Bolivia. The overall parasitism was 69%. Only protozoa, helminths, or co-infections were observed in 89.2%, 5.9%, or 4.9% of the positive children, respectively. A significant progressive increase in overall parasite prevalence was found when passing from rural areas to small villages and semi-urban areas. The most commonly found species were Entamoeba coli (38.4%), Giardia intestinalis (37.7%), and Blastocystis spp. (16%). Hymenolepis nana was the most prevalent helminth (5.6%), followed by Ascaris lumbricoides and hookworms (1.5% and 0.4%) evidenced only in rural areas and in villages. Molecular diagnostics identified Blastocystis subtypes 9 and 2, and 5 infections by Entamoeba histolytica and 4 by Entamoeba dispar. The dramatic decrease in prevalence of soil-transmitted helminths with respect to that observed about 20 years ago (> 40%) evidences the success of the preventive chemotherapy intervention implemented in 1986. Health education and improved sanitation should be intensified to control protozoan infections.

Both qualitative and quantitative methods were utilised such as: survey, focus groups, participatory observation, unstructured interviews to Key informants and open discussions with the community. Results show that the public health services reputation is affected by elements as discriminatory attitude towards people belonging to a low socio-economic strata, lack of communication between health workers and patients, perceived insufficient technical skills and recognition of a low therapeutic efficacy. The people who are coming from highlands (collas appear as the most disappointed by the health service provision structured on the western predominant pattern with a top-bottom approach ignoring its potential users' expectations and needs. A low capability of the public health services to accept and recognise the inter-cultural features of the region, makes that the challenge to be undertaken by the district health personnel should focus on the establishment of intercultural bridges betwen the public health service providers and the potential patients, as well as among the different co-existing medical systems.

    Logging activity in the trinational southwestern Amazonia will grow in importance as a driver of regional land-use change as expanding road access facilitates both timber extraction and transport to international markets. Official data on current activity in this ~50 million ha region are limited and inconsistent with differences as much as twenty-fold between official estimates; nevertheless, they serve as guides for understanding the relative magnitude of logging activities. For 2000, an estimated 5 million m3 of timber were commercialized in Rondonia, 400,000 m3 in Acre, Brazil, and 200,000 m3 for the combined departments of Pando, Bolivia and Madre de Dios, Peru. About 70% of this timber originates from clear cutting done for pasture and agriculture activities, nearly a third from unregulated selective logging, and only 2% from managed selective logging. Eight timber species are preferentially extracted. The total area for timber concessions in Acre, Pando and Madre de Dios extends to about 4 million ha for a potential timber supply of 65 million m3. About 150,000 m3/yr of illegal timber is confiscated by federal and state agencies in Acre, Pando and Madre de Dios. Problems of enforcement in the region are due principally to the lack of trained personnel and little cooperation among agencies of the three countries. Proposed development plans indicate a 3- to >10-fold increase in logging activity in the Acre and Pando regions during the coming decade. More detailed studies are urgently needed to guide sustainable development of this resource in southwestern Amazonia.

  7. Imaging the mid-crustal low velocity zone of the Altiplano-Puna magma body (Uturuncu volcano) in southern Bolivia from receiver functions

    Uturuncu volcano is located in the Altiplano-Puna volcanic complex, near the center of the Altiplano-Puna magma body (APMB) in southern Bolivia. The region has exhibited sustained uplift of 1 to 2 cm/yr for several decades over a broad region (70 km diameter). Uturuncu volcano and the surrounding area are the focus of an intensive multi-university study. The centerpiece of this study is a 40-station network of broadband seismometers that were deployed in the spring of 2010. At this time two full years of data have been retrieved from the network. Over 1200 receiver functions were determined from 65 teleseismic earthquakes. Receiver functions from similar back-azimuths and distances were then stacked to produce 49 average receiver functions that are used in this study. P-wave receiver functions clearly delineate the low velocity region associated with the APMB. This mid-crustal low velocity zone is present throughout the study area. While the APMB has been previously noted and described, the current network increases the station density in this region by a factor of 10. The top of the low velocity layer is associated with a large negative Ps arrival at about 2 seconds, corresponding to a depth of about 15 km (although there is scatter and variability in the depth modeling). This negative arrival is followed by a positive Ps arrival at around 3.5 seconds corresponding to the bottom of the low velocity zone at a depth of about 25 km. In general the low velocity zone is around 10-15 km thick, but once again with a fair amount of variability. The low velocity region corresponds well with estimates of the inflation source responsible for the observed uplift, and thus most likely represents an extensive region of partial melt, and potentially magma recharge, at the volcano. Arrivals from the Moho and subducting Nazca plate are obscured by the strong arrivals (including multiple reverberations) from the low velocity layer.

    Between October 16th and November 9th 2002, the first NASA Ames DDF Licancabur multidisciplinary expedition initiated the investigation of the biology and environment for life in the highest lake on Earth located at the summit of the Licancabur volcano (6017 m/20,056 ft) at the boundary of Chile and Bolivia. The low oxygen, low atmospheric pressure, high-UV radiation, average temperature, volcano-tectonic and hydrothermal environment make the site a close analog to Martian paleolakes 3.5 billion years ago. The overall goal of the project is to understand through a series of high altitude scientific expeditions what strategies life is using to defend itself against killer-level UV radiation and environmental extreme conditions at this altitude. Several other lakes are located at 4300 m at the foot of the Licancabur volcano (hereafter named laguna Blanca and Laguna Verde). They were also investigated using identical experiments and methods as for the summit lake in order to compare the results and better understand the evolution of survival strategies at transitioning elevations. The lagunas are geothermally heated and many springs provide water at various temperatures. Sources of heat are also suspected for the summit lake as its surface water temperature was measured during the successful ascent at +6 C in a -9 C ambient crater environment (with a wind chill factor of -25 C with a wind blowing almost constantly). Results of this project are expected to provide critical keys to help searching and identifying potential sites for life (extant/extinct) on Mars and developing instruments, experiments and technologies for future missions.

    The natural gas pipeline transport is carried out by one or more compression stations. Each station possesses one or more compressors. The compressor's fuel is usually natural gas itself. The amount of natural gas consumed by the compressors fluctuates daily according to the demand at the city-gates. The daily operational result of a pipeline is known as imbalance. The imbalance is the difference between the natural gas entering into a in a pipeline and the volume delivered in the city-gates added to system use gas. The imbalance analyses in a pipeline that uses natural gas powered compressors requires the analyses of the system use gas. The aim of this work is to study the system use gas in the Bolivia-Brazil pipeline using the available data from the Superintendencia de Comercializacao e Movimentacao de Petroleo, seus Derivados e Gas Natural - ANP and compare the change of the volume consumed before and after the entry into operation of the Campinas-Rio gas pipeline.

    TBG - Transportadora Gasoduto Bolivia-Brasil S.A, executes routine maintenance works at the Gas Pipeline Right of Way, seeking its integrity. In the wetlands of Pantanal, near the Paraguay river crossing, the organic-alluvial soil was submitted to the process of subsidence. This process, associated with the river water flow erosion, shrank the soil volume and diminished or extinguished the pipeline land cover. The pipeline was exposed to the environment, and submitted to tension stresses and the risk of low cycle fatigue during the floods. The cathodic protection system also had to be evaluated, specially in the drought. To mitigate the problem, the embankment technique was adopted using sandy soil, reinforced with polyester geo-webs and with woven polipropene geo-textiles. The solution also used geo-webs with soil-cement as protection elements against the degradation of the geo-textiles blankets. Some monitoring works are associated with those interventions: monitoring of cathodic protection; topographical verification of horizontal and vertical displacements of the pipeline; levels of land covering, and rainfalls and flood measurement. The base of the embankment was built with hydraulic transported soil, and at the end consistently supported the gas pipeline. (author)

    A hundred and seventy kilometers from Campo Grande city, on Mato Grosso do Sul State, the Brasil-Bolivia Gas Pipeline crosses a 8,5 meters high landfill, over a drainage systems made of a 2,8 meters of diameter corrugated pipe. This drainage pipe was installed to allow the drainage of the valley, and the landfill above it was built so the Gas pipeline could cross easier the 80 meters deep and 30 degree vertices valley. This paper illustrates the work tasks and solutions taken to monitor and guarantee the integrity of the drainage and landfill structures, as well as the integrity of the Gas Pipeline. Some of the work tasks illustrated are the investigation of the support conditions of the Gas Pipeline, the analysis of a drainage system under the pipeline, on a rocky soil, the analysis of the stability of the landfill, the construction of a gravity retaining walls and the monitoring of the deformations on the drainage pipe.

    Full Text Available Alalay Pond is a 230-hectare, shallow aquatic ecosystem within Cochabamba, the third largest city in Bolivia. With the aim to determine the suitability of epiphytic diatoms for water quality assessment in the pond and to choose a substrate that would hold a representative bioindicator epiphytic community, the macrophytes Schoenoplectus californicus subsp. tatora (Kunth T. Koyama, Typha dominguensis Pers., Myriophyllum verticillatum L. and Azolla filiculoides Lam. were selected and differences in diatom community composition and structure were tested. Diatoms were collected during four sampling campaigns in the March-September, 2011 period, from three stations contiguous to the pelagic zone and prepared for analysis using standard, internationally used protocols. In all, 27 samples were collected from which 28 taxa characteristic of eutrophic environments were identified and 17 others could not be assigned names from the literature. Although many of the species are shared among sampling sites, the epiphytic communities developing at each station were different in structure and composition. Although, there are marked temporal variations in community features on each of the macrophytes, Shannon-Wiener and Pielou indexes, as well as canonical correspondence analysis, showed no marked differences within a single campaign and station among the 4 macrophytes. Shifts in structure and composition are denoted less commonly by species replacement and more often by changes in percent relative abundance of dominant and rare species. Very few species are restricted to a station or seem to show strong preference for a particular substrate. Taking into account growth, structural and ecological characteristics, as well as some phenological features of the macrophytes, S. californicus subsp. tatora and T. dominguensis are the most suitable substrates for water quality assessments in the pond. As demonstrated by multivariate analyses, among-site and time

    The Río Colorado dryland river system in the southeast of the endorheic Altiplano Basin (Bolivia) terminates on a very flat coastal plain at the edge of the Salar de Uyuni, the world's largest salt pan with an area of ca. 12,500 km2. Since the Pleistocene the basin has experienced several lake expansion and contraction cycles in response to wetter and drier climate periods, respectively. At present the basin is in a dry climate period which results in a lake level lowstand and progradation of fluvial systems such as the Río Colorado onto the former lake bottom. The present field study of the terminus of the Río Colorado shows that the river experiences a gradual downstream decrease of bankfull width and depth. This bankfull decrease is caused by the combined effects of: (1) extremely low gradient of the lake bottom and, hence, loss of flow energy, and (2) downstream transmission losses due to high evaporation potential and river water percolation through the channel floor. Peak water discharge in seasonal, short-duration rain periods causes massive overbank flooding and floodplain inundation. On satellite images the morphology of the river terminus has a divergent pattern and resembles a network of coeval sinuous distributary channels. However, field observations show that only one channel is active at low flow stage, and at high-flow stage an abandoned, partially infilled channel may be active as well. The active channel at its termination splits into narrow and shallow anastomosing streams before its demise on the lacustrine coastal plain. The rest of the channels which form the divergent network are older sediment-filled abandoned sinuous river courses with multiple random avulsion points. These channel deposits, together with extensive amalgamated crevasse-splay deposits, form an intricate network of fluvial sand deposits. Successive stages of progressively deeper crevasse-channel incision into the floodplain are the result of waning-stage return flow of

    Full Text Available La cacería ilegal representa una amenaza para la conservación de la vida silvestre. Las motivaciones y efectos que puede tener son variables y aún no han sido ampliamente estudiados. Aplicando un enfoque teórico-conceptual económico analizamos los diferentes factores que pueden motivar la cacería ilegal y discutimos las implicaciones de gestión. Basándonos en el caso de la cacería ilegal que ocurre durante la recolección de castaña (Bertholletia excelsa en la Reserva de Vida Silvestre Amazónica Manuripi, Bolivia, analizamos los resultados de un extensivo estudio de incumpli- miento. En base a la revisión de fuentes primarias y secundarias de información y al marco conceptual referido a modelos económicos de disuasión, identificamos que la probabilidad de detección y sanción, la moralidad, la legitimidad y la influencia social pueden afectar el cumplimiento de la pro- hibición de caza en la Reserva Manuripi. Adicionalmente, consideramos que el conocimiento de la regulación también puede afectar la decisión de cazar y señalamos evidencia empírica que sugiere que el hábito de consumir carne silvestre y la no-disponibilidad de alternativas a la carne silvestre motivan la cacería ilegal en Manuripi. Bajo este análisis, las recomendaciones para disminuir el riesgo de cacería ilegal durante el periodo de reco- lección de castaña se enfocan en mejorar los esfuerzos de fiscalización, monitoreo y control por parte de la Autoridad Ambiental, paralelamente a la implementación de procesos de concientización dirigidos a modificar los valores éticos y hábitos culturales entre los recolectores.

    Full Text Available The objective of this study was to evaluate the proximal composition, as well as Total Antioxidant Capacity (TAC and Total Phenols (TPH in meals that represent a complex food matrix, from different hospitals in Bolivia and Sweden. Protein, fat, ash, dietary fiber and carbohydrate contents were measured in 29 samples: 20 from two Bolivian hospitals and 9 from the university hospital in Lund, Sweden. The antioxidant capacity was measured by three spectrophotometric methods: the ferric reducing antioxidant power (FRAP method, the 2, 2'- azinobis-3-ethylbenzotiazoline-6-sulfonic acid (ABTS method and Total Phenolic Compounds (TPH using the Folin-Ciocalteu reagent. The results show that fat, protein, carbohydrate and dietary fiber in Bolivian and Swedish hospital meals are following internationally established recommendations. Regarding the main courses, TPH contents in both countries were in the same range. However, TAC and dietary fiber content were higher in Swedish meals than in Bolivian meals and the TAC was far lower, in both cases, in comparison with the value obtained from individual food items reported from literature. The results show that antioxidant levels can be easily overestimated by considering only individual uncooked ingredients. An interesting consideration is, the fiber content in the meals, which can be an important source of antioxidants and non-extractable phenolic compounds.El objetivo de este estudio fue evaluar la composición proximal, así como la capacidad antioxidante total (CAT y los fenoles totales (FT en alimentos que representan una matriz compleja en diferentes hospitales de Bolivia y Suecia.

    A large amount of Hg is used for gold extraction through the amalgamation process in the Apolobamba gold mining area located in the northwest part of La Paz, Bolivia. This mining operation may produce a very serious impact on the ecosystems, as well as on the health of miners and inhabitants, mainly due to the primitive methods used in the gold recovery. The objective of this work was to characterize the potential contamination of total Hg in soils, sediments, water, and plants in a mining area of Bolivia. Results showed that there was atmospheric deposition of Hg in the study area. Accumulation of this metal in the studied soils and sediments was one of the highest in the world, but Hg in aquatic solution was below the detection limit of the analytical method of the studied lakes and rivers. The highest concentration of Hg was found in the river sediments of the Sunchullí- Viscachani (102 mg kg-1, and in the sediments of Sunchullí and Viscachani lakes (12.3 and 11.7 mg kg-1, respectively. These concentrations may pose a serious problem for aquatic life, related ecosystems and human health. Therefore, there is a need to study Hg availability and speciation in soils and sediments to better understand the cycling of Hg in the area.

    Epilepsy is associated with a significant burden of social stigma that appears to be influenced by psychosocial and cultural factors. Stigma has a negative effect on the management of people with epilepsy (PWE), representing one of the major factors that contribute to the burden of epilepsy. To assess stigma perception among the Guarani population, one hundred thirty-two people living in Guaraní communities in Bolivia were invited to complete the Stigma Scale of Epilepsy questionnaire. The main determinants of stigma identified were: the fear linked to loss of control, the feelings of sadness and pity toward PWE, the difficulties faced by PWE in the professional and relationship fields, the level of education and type of seizure. Our study pointed out that, in this population, PWE face difficulties in everyday life because of epilepsy-associated stigma and the results attest to the importance of promoting community-based educational programs aimed at reducing the stigmatization process.

    Southwestern Amazonia, where Bolivia, Brazil and Peru meet, faces numerous challenges to the sustainable utilization of land and water resources as the region experiences rapid population and economic growth, expanding agriculture, transportation and energy sectors, along with frequent flooding and droughts. It is also predicted to be one of the most susceptible areas for climate change in the coming decade. The Acre River Basin, one of the few trinational basins in Amazonia, lies at the center of the Madre de Dios Region (Peru), Acre State (Brazil) and Pando Department (Bolivia) or MAP Region. It covers approximately 7,500 km2 and its inhabitants range from indigenous groups avoiding contact with industrial society to more than 60,000 dwellers of a binational urban center. The basin incorporates most the challenges facing the region and this paper discusses steps underway to address the basin's vulnerability to climate-related threats. A trinational group of professionals used GIS databases and local knowledge to classify these threats and possible societal responses. To prioritize threats and to propose responses, this group adapted a method proposed by the Queensland Climate Change Centre of Excellence of Australia to develop climate risk matrices for assessing impacts, adaptation, risk and vulnerability. The three priority climate variables were prolonged and more frequent droughts, more intense flooding, and more days with temperatures > 35oC. The final matrix proposed two areas of concentration - 1) Reduce the vulnerability of communities to hydro-meteorological extreme events and 2) Protect and restore ecosystems that maintain critical water-related resources with actions in public policy, capacity-building, and immediate activities.

    The Pensamiento Granitoid Complex (PGC), located in the northern part of the eastern Precambrian shield of Bolivia, is tectonically assigned to the Rondonian-San Ignacio Province (1.55 - 1.30 Ga) of the Amazonian Craton that is made up by Archean and Proterozoic provinces. The Proterozoic ones result from accretionary orogens that become successively younger south westwards, such as the Rondonian/San Ignacio (1.37 - 1.32 Ga) and the Sunsas orogenies (1.20 - 1.00 Ga). The PGC crops out mainly on the 'Paragua craton' bounded to the south by the Sunsas belt, and composed of granites and subvolcanic terms, and subordinately of syenites, granodiorites, tonalites, trondhjemites and diorites as orogenic representatives of the Rondonian/San Ignacio Orogeny, intrusive into the Lomas Maneches (ca. 1.68 Ga) and Chiquitania (ca. 1.7 Ga) complexes. Thirteen whole rock chemical analyses for major, trace and REE elements were performed for the La Junta, San Martin, Diamantina, Porvernir, San Cristobal, Piso Firme plutons of the PGC. The negative trends of MgO, Al{sub 2}O{sub 3} and CaO contents with increasing SiO{sub 2} suggest that fractional crystallization played an important role in the petrogenesis of the investigated rocks. The data also indicate a mainly peraluminous, sub-alkaline to high-K calc-alkaline composition, and fractionated LREE/HREE patterns are consistent with a magmatic arc character for these plutons. SHRIMP U-Pb zircon ages of the La Junta and San Martin syn- to late-kinematic plutons are 1347 {+-} 21 Ma and 1373 {+-} 20 Ma respectively, and the Sm-Nd T{sub DM} model ages are between 1.9 to 2.0 Ga, while {epsilon}{sub Nd(1330)} values range from +1.8 to -4.3, respectively. In addition, the late- to post-kinematic Diamantina pluton yields SHRIMP U-Pb zircon age of 1340 {+-} 20 Ma, and variable Sm-Nd T{sub DM} model ages (1.6 to 1.9 Ga) and {epsilon}{sub Nd(1330)} values (+0.4 to -1.2) that are comparable with previous results found for other coeval

Realizado en Cochabamba (Bolivia, Talca (Chile y Guadalajara (México entre 2007 y 2008. Un total de 184 jóvenes (de 14 y 19 años de edad fueron seleccionados por muestreo propositivo en centros de estudios de educación media superior de cada país. Fueron utilizadas las técnicas de listados libres y el sorteo de montones. Se indagaron términos asociados al concepto VIH/Sida y grupos de dimensiones conceptuales. Posteriormente se aplicó análisis de consenso mediante factorización de componentes principales y análisis dimensional mediante conglomerados jerárquicos y escalas multidimensionales. RESULTADOS: Las diferencias entre los contextos fueron en el grado de consenso en relación al término de VIH/Sida, ya que fue mayor en Cochabamba. En Talca y Guadalajara los jóvenes mencionaron metáforas de lucha frente a la enfermedad, mientras en Cochabamba se refirieron a la ayuda, apoyo y amor que las personas infectadas deberían recibir. Las coincidencias entre las conceptualizaciones de los jóvenes de los tres países fueron: los riesgos (las prácticas sexuales desprotegidas y el contacto con algunos grupos poblacionales específicos, las consecuencias (muerte física y social, entendida ésta última como el rechazo de la sociedad hacia los enfermos y la prevención de la enfermedad (con base en la información así como uso del condón. CONCLUSIONES: Para los estudiantes adolescentes el VIH/Sida es una enfermedad causada por prácticas sexuales y consumo de drogas que implica daño, dolor y muerte. Los programas preventivos del VIH/Sida para los adolescentes deben promover la búsqueda de información sobre el tema con bases científicas, y no centrarse en las consecuencias emocionales y sociales de la enfermedad.OBJETIVO: Compreender as dimensões culturais do HIV/Aids por estudantes adolescentes.

    Full Text Available Background: It is widely agreed upon that gender is a key aspect of sexuality however, questions remain on how gender exactly influences adolescents’ sexual health. Objective: The aim of this research was to study correlations between gender equality attitudes and sexual behavior, sexual experiences and communication about sex among sexually active and non-sexually active adolescents in 2 Latin American countries. Design: In 2011, a cross-sectional study was carried out among 5,913 adolescents aged 14–18 in 20 secondary schools in Cochabamba (Bolivia and 6 secondary schools in Cuenca (Ecuador. Models were built using logistic regressions to assess the predictive value of attitudes toward gender equality on adolescents’ sexual behavior, on experiences and on communication. Results: The analysis shows that sexually active adolescents who consider gender equality as important report higher current use of contraceptives within the couple. They are more likely to describe their last sexual intercourse as a positive experience and consider it easier to talk with their partner about sexuality than sexually experienced adolescents who are less positively inclined toward gender equality. These correlations remained consistent whether the respondent was a boy or a girl. Non-sexually active adolescents, who consider gender equality to be important, are more likely to think that sexual intercourse is a positive experience. They consider it less necessary to have sexual intercourse to maintain a relationship and find it easier to communicate with their girlfriend or boyfriend than sexually non-active adolescents who consider gender equality to be less important. Comparable results were found for boys and girls. Conclusions: Our results suggest that gender equality attitudes have a positive impact on adolescents’ sexual and reproductive health (SRH and wellbeing. Further research is necessary to better understand the relationship between gender

    Full Text Available Since the entry into force of the new Constitution (January 2009, Bolivia has experienced important political and institutional transformations, marked by the spotlight of indigenous peoples after decades of strong mobilizations. In the heart of these transformations, the proclamation of Bolivia as a “Plurinational State” and the extensive recognition of indigenous peoples’ collective rights feature prominently. Among these rights, the right to self-determination stands out, opening up the door to the establishment of indigenous autonomy systems. However, even when the Bolivian Constitution is the most advanced of Latin America in the field of the recognition of indigenous peoples’ collective rights, its implementation is facing many challenges. This situation creates a significant gap between the formal model of Plurinational State and the Plurinational State in practice, as it is attested by the existence of multiple burocratic hurdles posed to the indigenous autonomies prior to its full establishment. The long list of administrative requirements illustrate the lack of political will of the State, despite the fact that on 6 December 2009, 11 municipalites started the process of “conversion” to the autonomy. In this context, the present paper gives an account of the distance between the model and its implementation through an analysis of the system of indigenous autonomies, which draws on the case study of the Charagua Iyambae Guarani Autonomy and its new governance system.

Despite economic integration and bilateral cooperation, the border remains a sensitive issue and has been the source of diplomatic and military tension. The two countries must surpass these difficulties stemming from the collective memory of the armed conflict between them.

    Background The peak shift model predicts that the age-profile of a pathogen's prevalence depends upon its transmission rate, peaking earlier in populations with higher transmission and declining as partial immunity is acquired. Helminth infections are associated with increased immunoglobulin E (IgE), which may convey partial immunity and influence the peak shift. Although studies have noted peak shifts in helminths, corresponding peak shifts in total IgE have not been investigated, nor has the age-patterning been carefully examined across populations. We test for differences in the age-patterning of IgE between two South American forager-horticulturalist populations and the United States: the Tsimane of Bolivia (n = 832), the Shuar of Ecuador (n = 289), and the U.S. NHANES (n = 8,336). We then examine the relationship between total IgE and helminth prevalences in the Tsimane. Methodology/Principal Findings Total IgE levels were assessed in serum and dried blood spots and age-patterns examined with non-linear regression models. Tsimane had the highest IgE (geometric mean  = 8,182 IU/ml), followed by Shuar (1,252 IU/ml), and NHANES (52 IU/ml). Consistent with predictions, higher population IgE was associated with steeper increases at early ages and earlier peaks: Tsimane IgE peaked at 7 years, Shuar at 10 years, and NHANES at 17 years. For Tsimane, the age-pattern was compared with fecal helminth prevalences. Overall, 57% had detectable eggs or larva, with hookworm (45.4%) and Ascaris lumbricoides (19.9%) the most prevalent. The peak in total IgE occurred around the peak in A. lumbricoides, which was associated with higher IgE in children <10, but with lower IgE in adolescents. Conclusions The age-patterning suggests a peak shift in total IgE similar to that seen in helminth infections, particularly A. lumbricoides. This age-patterning may have implications for understanding the effects of helminths on other health outcomes, such as allergy, growth

    Full Text Available Abstract Background The main objective of the present study was to investigate the relationship between the attitudes of the mother and her family towards breastfeeding and the actual feeding pattern in a Bolivian population. A second objective was to study the relationship between breastfeeding information, specified according to source and timing, and feeding pattern. Methods Cross-sectional interviews with 420–502 Bolivian mothers with an infant less than or equal to 1 year of age. Duration of exclusive breastfeeding, use of prelacteal food and/or colostrum were the main outcome measures. Results The attitudes of the mother, her partner (the infant's father and the infant's grandmother towards breastfeeding did not influence the infant feeding pattern. Women who had received breastfeeding information from health care personnel before birth or on the maternity ward breastfed exclusively for a longer duration (adjusted p = 0.0233 and avoided prelacteal food to a greater extent (adjusted odds ratio (AOR = 0.42; 95% confidence interval for adjusted odds ratio (95% CI AOR = 0.23–0.72. Information from a doctor before birth or on the maternity ward was associated with less use of prelacteal food (AOR = 0.53; 95% CI AOR = 0.31–0.93, an increased use of colostrum (AOR = 3.30; 95% CI AOR = 1.16–9.37, but was not linked to the duration of exclusive breastfeeding (p = 0.1767. Conclusion The current study indicates that breastfeeding information delivered by health care personnel in a non-trial setting may affect the infant feeding pattern including the use of prelacteal foods and colostrum. There was no evidence that the attitudes of the mother, or the infant's father or grandmother influenced actual feeding behavior. The lack of a "negative or neutral attitude" towards breastfeeding in the participants of the current study does, however, diminish the chances to link attitude to feeding behavior.

    Full Text Available INTRODUCTION: A descriptive, entomological and seroepidemiological study on Chagas disease was conducted in a place of recent occupation on the outskirts of Cochabamba, Bolivia: Avaroa/Primer de Mayo (population:3,000, where the socio-economic level is low and no control measures have been made available. METHODS: The immunofluorescent antibody test (IFAT was used for IgG and IgM anti-Trypanosoma cruzi antibodies in filter paper bloodspot eluates from 128 subjects (73 females, 55 males selected by systematic sampling. Concerning each subject age, gender, birthplace, occupation, duration of residence and building materials used in their houses were recorded. Vectors were captured both in domestic and peridomestic environments. RESULTS: Seropositive, 12.5% (16/128: females, 15.1% (11/73; males, 9.1% (5/55. Average time of residence: 6.1 years for the whole population sample and 7.4 years for the seropositive subjects. Most houses had adobe walls (76.7% , n= 30, galvanized iron rooves (86.7% and earthen floors (53.4% 80% of the walls had crevices. One hundred forty seven specimens of Triatoma infestans were captured, of which 104 (70.7% were domestic, and 1 peridomestic Triatoma sordida. Precipitin host identification: birds, 67.5%; humans, 27.8%; rodents, 11.9%; dogs, 8.7%; cats, 1.6%. House infestation and density indices were 53.3 and 493.0 respectively. We found 21 (14.3% specimens of T. infestans infected with trypanosomes, 18 (85.7% of which in domestic environments. DISCUSSION: The elements for the vector transmission of Chagas disease are present in Avaroa/Primer de Mayo and the ancient custom of keeping guinea pigs indoors adds to the risk of human infection. In neighboring Cochabamba, due to substandard quality control, contaminated blood transfusions are not infrequent, which further aggravates the spread of Chagas disease. Prompt action to check the transmission of this infection, involving additionally the congenital and transfusional

    The Los Frailes Meseta (Bolivia) is one of the large tertiary ignimbritic fields of the inner volcanic arc from Central Andes (Central Volcanic Zone. CVZ), in contact zone between the Altiplano to the west and the Eastern Cordillera to the east. Field observations and mineralogical and geochemical studies (major and trace elements) lead to distinguish two types of volcanism in the western border to the Meseta. During the Middle Miocene and Pliocene, the volcanic activity can be subdivided into three pyroclastic emission cycles, the Larco, Coroma and Pliocene ignimbrites, the first two being separated by the Quechua 2 orogeny. All these ignimbrites are very similar and correspond to peraluminous rhyolites to rhyodacites. In the studies area, the Coroma cycle is the only one where an ignimbrite-less evolved resurgent dome association can be observed. Beside these ignimbrites, isolated small lava flows and domes overlay and/or intrude all the other formations. They are meta-aluminous lavas with a shoshonitic affinity. A quaternary age can be attributed to his second volcanism. These two volcanic types are well-known in the CVZ and are related to the different deformation stages, either compressional or extensional, which occur alternately in the Cordillera since 26 Ma.

As biological material it was used 40 lambs, of 7 positive months to the cestodiasis. The population in study conformed in 4 groups of 10 individuals beginning the treatment the day zero with the autopsy. G1 received ABZ 5%, 8.3 mg / kg weight, G2, ABZ 20%, 10 mg / kg, G3, FBZ 10%, 10 mg / kg, G4, fungió like group witness without treatment. The evaluation parameter was the presence or absence of mature cestodos in the carried out autopsies of two animals for group in the days 0, 14, 28, 42 and 56. The effectiveness was evaluated to 14, 28 and 42 days, of 100% having used ABZ 5% and ABZ 20%, 100%, 36% and 34.7% for FBZ 10%. The effect extension and intensity was of 100% of the three antiparasitarios infested with Thysanosoma actinioides, analyzed in the days 14, 28 and 56, for ABZ 20%, 100%, 100% and 0% for ABZ 5%, 100%, 0% and 0% for FBZ 10%, with relationship to the infestación with Moniezia expanza, analyzed in the same days, ABZ 20% and ABZ 5% stand out with 100% and lastly FBZ 10% with 100%, 100% and 0%. ANVA was statistical differences for the interactions antiparasitario for parasite type, antiparasitario for time of evaluation and you concludes that the antiparasitarios ABZ 5% and ABZ 20% reduced the cestodos number, with what was demonstrated as products recommended for the treatments against the parasites and in fact in the control of M. expanza and T. actinioides in the production of having won ovino.

    This article is a reflection on how interculturality, understood as the way to improve the health of the Bolivian population and coupled with the concept of living well, is not contributing to improving the quality of life and health of the most vulnerable populations in the country. The discourse is coupled with the intention of saving lives in its broadest sense; however, for this it is necessary to make decisions about environmental health and extractivist policies that are not taken into account in the health issues affecting indigenous communities, a population targeted by the intercultural aspects of the health reform.

    This paper uses microeconometric simulations to characterize the distributional changes occurred in the Bolivian economy in the period 1993-2002, and to assess the potential distributional impact of various alternative economic scenarios for the next decade. Wage equations for urban and rural areas estimated by both OLS and quantile regression are the main inputs for the microsimulations. A sizeable increase in the dispersion in worker unobserved wage determinants is the main factor behind th...

    Recent analyses of brines from the Salars of Uyuni and Coipasa have been compared with published data for Lakes Titicaca and Poopo to evaluate solute compositional trends in these remnants of two large Pleistocene lakes once connected by overflow from the N to the S of the Bolivian Altiplano. From Titicaca to Poopo the water shows an increase in Cl and N somewhat greater than the total solutes. Ca and SO4 increase to a lesser extent than total dissolved solids, and carbonate species are relatively constant. Between Poopo and Coipasa proportions of Ca, SO4 and CO3 continue to decrease. At Coipasa and Uyuni, the great salars frequently evaporate to halite saturation. Halite crystallization is accompanied by an increased K, Mg and SO4 in residual brines. - from Authors
