    Full Text Available The author reviews the malaria research program in Sucre State, Venezuela, taking an ecosystem approach. The goal was to determine which methods could have been introduced at the onset that would have made the study more ecological and interdisciplinary. Neither an ecosystem approach nor integrated disease control were in place at the time of the study. This study began to introduce an ecosystem approach when two contrasting ecosystems in Sucre State were selected for study and vector control methods were implemented based on research results. The need to have a health policy in place with an eco-health approach is crucial to the success of research and control. The review suggests that sustainability is low when not all the stakeholders are involved in the design and implementation of the research and control strategy development. The lack of community involvement makes sustainability doubtful. The author concludes that there were two interdependent challenges for malaria control: development of an ecosystem approach for malaria research and control, and the implementation of an integrated disease control strategy, with malaria as one of the important health issues.O autor faz uma revisão do programa de pesquisa sobre malária no Estado de Sucre, Venezuela, à luz de uma abordagem ecossistêmica. O objetivo era determinar quais métodos poderiam ter sido introduzidos no início do estudo para torná-lo mais ecológico e interdisciplinar. A fase inicial do estudo não incluía uma abordagem ecossistêmica ou controle integrado da doença, que só foram incorporados quando dois ecossistemas contrastantes no Estado de Sucre foram selecionados para pesquisa, junto com um método de controle de vetores com base nos resultados. Uma política de saúde bem-definida com uma abordagem ecossistêmica é crucial para o sucesso de uma estratégia de pesquisa e controle. Esta revisão sugere que a sustentabilidade é baixa se todos os atores não estiverem

    Yardlong bean (Vigna unguiculata subsp. sesquipedalis) plants with virus-like systemic mottling and leaf distortion were observed in both experimental and commercial fields in Aragua State, Venezuela. Symptomatic leaves were shown to contain carlavirus-like particles. RT-PCR analysis with carlavirus-specific primers was positive in all tested samples. Nucleotide sequences of the obtained amplicons showed 84%-74% similarity to corresponding sequences of Cowpea mild mottle virus (CPMMV) isolates deposited in the GenBank database. This is the first report of CPMMV in Venezuela and is thought to be the first report of CPMMV infecting yardlong bean.

    Full Text Available La construcción de nuevas vías de comunicación, genera sin lugar a dudas, impactos positivos, ya que éstas, facilitan la integración de centros poblados y contribuyen a fortalecer el desarrollo económico de estos espacios. Sin embargo, esta actividad también produce impactos negativos al ambiente, tales como: la degradación de los suelos, la pérdida de cobertura vegetal, la alteración en la calidad del agua, la disminución de la fauna local, por mencionar algunos; y, a la sociedad la alteración de la calidad de vida, ruidos que afectan la normal convivencia, molestias debido al incremento del tráfico, entre otros. La presente investigación evalúa los posibles impactos ambientales y socioeconómicos, que generaría la construcción de la Autopista Regional del Sur en el eje La Victoria–San Sebastián de los Reyes, estado Aragua. Para lograr este objetivo, se aplicó el método de sensibilidad ambiental y la matriz de Leopold, los cuales permitieron identificar los posibles impactos y, predecir su riesgo, duración, intensidad, extensión y reversibilidad. Los resultados arrojaron que las consecuencias más significativos que podrían ocurrir al desarrollar este proyecto son: el deterioro de las cuencas hidrográficas de los ríos Pao y Caramacate, que abastecen de agua potable a los pobladores del municipio San Sebastián de Los Reyes; la alteración de la calidad del agua, principalmente la del río Pao, que se originaría por la disposición inadecuada de desechos; además del incremento del riesgo de incendios de vegetación, a lo largo del eje vial. Mientras que entre los impactos positivos están la conexión vial directa, en sentido norte-sur entre La Victoria y San Sebastián de los Reyes, la generación de empleos, tanto en las etapas de construcción como en las de ejecución del proyecto, y el desarrollo de las actividades agrícolas, ya que se contará con una vialidad apropiada que permitiría trasladar estos rubros

  11. Venezuela.

    1982-02-01

    This discussion of Venezuela reviews the following: the history of the country's demographic situation; the government's overall approach to population problems; statistical systems and development planning; institutional arrangements for the integration of population within development planning; the government's view of the importance of population policy in realizing development objectives; population size, growth, and natural increase; morbidity and mortality; fertility; international migration; and spatial distribution. Over the 1920-1961 period Venezuela's level of fertility was high and continued to rise gradually. The crude birth rate was around 40.0/1000 population in 1920, 44.0/1000 in 1950, and 45.0/1000 in 1961, and thereafter began to decline, dropping to a level of 38.4/1000 by 1971. During the same period, mortality underwent a steady decline, with the crude death rate falling from 30.0/1000 population in 1920 to 13.7 in 1950, 7.4 in 1961, and to 6.6 by 1971. Venezuela's government has no policy of intervention to modify fertility or population growth but has relied primarily on the benefits of rapid economic growth to achieve a rate of demographic growth that is compatible with its development objectives. Since 1920, 7 modern censuses have been conducted. The most recent census was in 1971. The registration data are classified as incomplete. Multiround sample household surveys were conducted in 1976-1977 and 1978. The government has not established a special unit for population policies. It assigned this function to the Central Planning Agency in 1975. The government has not announced a comprehensive population policy, but it has been moving in the direction of formulating more comprehensive policies in 2 areas of concern--international migration and spatial distribution. The government considers the current rate of population growth to be satisfactory despite the fact that it is rather high by Latin American standards. The government also considers

    Drug-induced liver injury (DILI) is an important cause of morbidity and mortality worldwide, with varied geographical differences. The aim of this prospective, descriptive, cross-sectional study was to identify and characterize cases of DILI in a hospital of Zulia state, Venezuela. Thirteen patients with a presumptive diagnosis of DILI attended by the Department of Gastroenterology, Hospital Universitario, Zulia state, Venezuela, from December-2012 to December-2013 were studied. Ibuprofen (n = 3; 23.1%), acetaminophen (n = 3; 23.1), isoniazid (n = 2; 15.4%) and Herbalife products (n = 2; 15.4%) were the main drugs involved with DILI. Acetaminophen and ibuprofen showed a mixed pattern of liver injury (n = 3; 23.1%) and isoniazid presented a hepatocellular pattern (n = 2; 15.4%). The CIOMS/RUCAMS allowed the identification of possible (n = 7; 53.9%), probable (n = 4; 30.8%) and highly-probable cases (n = 2; 15.4%) of DILI. Amoxicillin/clavulanate, isoniazid, isotretinoin, methotrexate and Herbalife nutritional products were implicated as highly-probable and probable agents. The highest percentage of DILI corresponded to mild cases that recovered after the discontinuation of the agent involved (n = 9; 69.3%). The consumption of Herbalife botanical products is associated with probable causality and fatality (n = 1; 7.7%). In conclusion, the frequency of DILI cases controlled by the Department of Gastroenterology of the Hospital Universitario of Maracaibo was low, being ibuprofen, acetaminophen, isoniazid and products Herbalife the products most commonly involved. It is recommended to continue with the prospective registration of cases, with an extended follow up monitoring period and to facilitate the incorporation of other hospitals in the Zulia State and Venezuela.

    A cross-sectional survey was conducted to determine the prevalence of Blastocystis hominis infection in a random sample of apparently healthy food handlers. A total of 415 individuals attending the Manoa Urban Outpatient Clinic (Caroní Municipality, Bolívar State, Venezuela) in the Adult Hygiene Program and who requested health certification to work as food handlers were studied. Stool samples obtained by spontaneous evacuation were examined by direct microscopy and the Willis concentration method. A total of 150 individuals were infected (36.14%), 107 (25.78%) of whom with B. hominis. There was no difference between males and females (p > 0.05), but there was a significant difference between ages (chi(2) = 12.17; g.l. = 4), with infection more frequent between 18 and 27 years. In 71.02% of the cases, B. hominis was the only parasite. Giardia lamblia was the parasite most frequently associated with B. hominis (2.41%). In the majority (85%) of infected individuals, less than five microorganisms per microscopic field were observed. We conclude that B. hominis is a frequent intestinal parasite among food handlers in Caroní Municipality, Bolivar State, Venezuela.

    In Venezuela, human Fasciolosis shows a low frequency. However, Mara Municipality is a highly endemic region for bovine fasciolosis and there are no reports of this parasite infection in humans. To determine the prevalence and associated factors to human fasciolosis in Mara municipality - Zulia state, a total of 51 blood and stool samples were collected. Serums were tested by ELISA and Western Blot (WB) assays, with excretion-secretion antigens of Fasciola hepatica (AFhES). The serum samples that resulted positive by these assays were tested by ELISA IgG anti Toxocara sp, Toxoplasma gondii and cysticerosis. Stool samples were concentrated by the Ritchie and rapid sedimentation techniques. Two serum samples were reactive to ELISA AFhES (3.9%) and these did not recognize the specific molecules of WB-AFhES detected by serum from patients with an absolutely demonstrated infection. Both participants were not positive to IgG anti Toxocara sp, Toxoplasma gondii, cysticerosis, and stool samples of these were negative to intestinal parasites. The general prevalence of intestinal parasites was 52.9% (27/51), being protozoa more frequent than helminthes. No Fasciola eggs were found. The two positives participants had in common that both had worked as fresh pasture cutters. These results suggest that the population had been in contact with F. hepatica, with no active infection because of the lack of specific molecules recognition and the absence of eggs in stool samples. Human fasciolosis has a low frequency in Venezuela and is underestimated and underrecognized by health workers and the general population.

    Venezuela offers a unique case and fertile ground for the study of oil policy-making processes. In the specialised literature very little attention has been paid to the nature and operations of multinationals from developing countries. By analysing Petroleos de Venezuela SA's (PDVSA's) internationalisation policy, this unique book explores the difficulties encountered by a major state oil enterprise in its efforts to grow beyond national borders. This informative study focuses on the impact of democratic bargaining on the process of oil policy-making in Venezuela, stressing the constraints posed by politics on PDVSA's efforts to expand its foreign operations.

    This work was conducted to determine the occurrence of Trichogramma wasp species in Lara State, Venezuela. Lepidopteran egg samples collected from various crop leaves were observed daily under laboratory conditions for emergence of Trichogramma species adult wasps. Trichogramma were also obtained from traps containing eggs from the hosts Sitotroga cerealella (Olivier) (Lepidoptera: Gelechiidae) and Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae). In the laboratory, specimens of Trichogramma species were mounted on microscope slides to show male genitalia and other morphological characters used for its identification. Trichogramma atopovirilia Oatman y Platner emerged from S. frugiperda eggs collected in a cornfield at La Palomera, Humocaro Alto and at El Parchal, Humocaro Bajo, Municipio Morán. T. atopovirilia also emerged from S. frugiperda eggs collected in a cornfield at Sabana Grande and from S. cerealella eggs used as traps in a pepper culture at Tintinal, Municipio Andrés Eloy Blanco. T. exiguum Pinto y Platner emerged from S. frugiperda eggs used as traps or collected in cornfield at Totumito and at La Palomera, Humocaro Alto. T. pretiosum Riley emerged from Phthorimaea operculella Zeller eggs collected on stored potatoes at Monte Carmelo, Sanare. The identification of Trichogramma species in Lara State would be useful in the development of biological control programs for lepidopteran pests.

    A total of 16 new species records of Culicidae from Falcon State was collected at the "Juan Crisostomo Falcon National Park" (Sierra de San Luis), Natural Monument "Cerro Santa Ana", Coro, and La Vela. Species of Sabethini, Culicini and Toxorhynchitini Tribes were found in natural breeding sites (Phytotelmata), with special occurrence in plants belonging to Tillandsia, Vriesea, Guzmania, Aechmea (Bromelianceae), Heliconia (Heliconiaceae), Calathea (Marantaceae) and Colocasia (Araceae). Aedini and Mansonini were collected only as adults. A specie of Culex (Carrollia) was collected from an artificial container. The Culicidae species belong to 6 genera out of the 23 genera reported from Venezuela (Culex, Wyeomyia, Johnbelkinia, Aedes, Psorophora, Mansonia and Coquillettidia) and to 5 Tribes out of the 9 present in the country. The Aedini, Sabethini and Culicini Tribes were richer in species with 5, 4 and 4 species, respectively, than the Mansonini (2 species) and Toxorhynchitini (1 species) Tribes. We discuss some bioecological aspects regarding the 16 new-species records in Falcon State and give a checklist of the mosquito species previously reported in the literature.

    Cryptosporidiosis in food handlers from Venezuela is unknown, being this an important public health problem in immunosuppressed patients. To determine the prevalence of Cryptosporidium sp and other intestinal parasites in food handlers from Zulia State, one hundred nineteen fecal samples were evaluated by wet mount, concentrated according to Ritchie and modified Ziehl-Neelsen staining. Fourteen (11.8%) were positive for Cryptosporidium sp and associated with other protozoosis (P < 0.05), being most frequent Endolimax nana (42.9%). The general prevalence of the intestinal parasitism was 48.7%, emphasizing E. nana (41.2%), followed by Blastocystis hominis (38.7%) and Entamoeba coli (17.6%). The most frequent pathogenic protozoa was Giardia lamblia (13.4%), followed by the complex Entamoeba histolytica/E. dispar (9.2%). 4.1% were positive for intestinal helminthes. The infection by Cryptosporidium sp is frequent in food handlers from Zulia State. Given to the results of this investigation and the nonexistence of studies in this population, is necessary to deepen in the impact of this parasitism in food handlers and the consumers of their products.

    The primordial objective of this study was to carry out an epidemiological analysis of sexually transmitted diseases (STD) in terms of sensed morbidity and real morbidity in the mining region of "Las Claritas", Bolivar State, Venezuela, during the third trimester of 1998. The epidemiological characteristics of time, people and place are interlaced, giving a relationship included within the Epidemiological Triad, that represents this work's conceptual framework; defining both, the determinant and the conditioning factors of the presence of STDs in the zone. The clinical interrogatory was partially steered towards the participant's sensed morbidity. A mostly feminine population is described (65%), with a low scholarly level in the general population and a high index of foreigners among the evaluated patients; with 48.72% of stable unions in the interviewees. From 166 evaluated patients, 27.70% referred to have had some STD episode, being syphilis and blenorrhagia the most frequently reported. In the survey, there was a general hush concerning the presence of STDs; but, key informants such as the medicine retailers, revealed a higher presence of these diseases, which are wrongly treated by automedication. These are important results, since they let opened a space for the epidemiological evaluation in the zone, in the various health, sanitary, environmental and social aspects and mainly, by the individual's quality of life expectations.

    A nematode from the genus Steinernema was isolated in Zulia state (North-western, Venezuela). Morphological, morphometric and molecular studies indicated that this nematode belongs to the "bicornutum" group and is described herein as Steinernema goweni n. sp. Steinernema goweni n. sp. is characterised by morphometrics of its infective juveniles, with body length 640 (531-719) µm, pharynx length of 119 (109-126) µm, tail of 67 (59-89) µm, c ratio = 9 (6-11) and E% = 77 (48-94). First generation male specimens can be recognised by the shape and size of spicules (55 (50-57) µm long) and gubernaculum (35 (30-40) µm long), and %D value 42 (28-59), which is at the lower limit within the "bicornutum" group. The number of genital papillae in males is also distinctive for S. goweni n. sp. presenting up to 27 (13 pairs + 1) papillae in 15% of specimens. The phasmids can be seen in scanning electron microscopy in all stages, characters not previously reported within the "bicornutum" group. Phylogenetic analyses of the "bicornutum" group based on both ITS and D2D3 regions showed a clear separation of S. goweni n. sp. from the other species. In both analyses S. goweni n. sp. formed a strongly supported group of American species.

    The intestinal coccidioses caused by Cryptosporidium parvum, Isospora belli, and Cyclospora cayetanensis are parasitoses of major medical importance, but many epidemiological aspects of these infections are still unknown in Bolívar State, Venezuela. To determine the prevalence of intestinal parasites and especially of intestinal coccidiosis, an indigenous population in San Antonio de Morichal was evaluated from July 2003 to April 2004. Stool samples obtained by spontaneous evacuation were preserved in potassium dichromate 2.5% and examined by the formalin-ether concentration method and Kinyoun staining. Of the 160 indigenous people examined, 92.5% (148 cases) were infected. Entamoeba coli (58.8%), Ascaris lumbricoides (38.8%), and Giardia lamblia (18.8%) were the most prevalent intestinal parasites. Coccidiosis prevalence was 13.1%, and cyclosporiasis was the most prevalent with 11.9% (19 cases). One subject with C. parvum oocysts and another with I. belli oocysts were diagnosed. There was no difference according to sex (p > 0.05) and age (chi2 = 5.6; f.g. = 6) among individuals infected with C. cayetanensis. Of these, two cases had only diarrhea. In conclusion, a high prevalence of intestinal coccidiosis infection was found among indigenous people from this community, with C. cayetanensis as the most prevalent infection.

    Roads directly or indirectly affect the structure, dynamics and function of ecosystems that they traverse. Most studies on the effect of roads on wildlife focus on the evaluation of mortality of vertebrates by vehicle collisions. Despite the extensive road network that exists in Venezuela, studies of wildlife mortality in them are scarce. In this paper, we analyzed the temporal and spatial pattern of vertebrate's collisions along the road Guanare-Guanarito, in Portuguesa state. We travelled 26 times between these towns (74 km) to localize dead vertebrates, at a speed of 50-60km/h. of those trips were conducted from March 13 to October 26, 2010, and 10 additional trips from December 7, 2009 to December 14, 2010; these ones, with the aim to include months and seasons that were insufficiently sampled during the first period. The elapsed time between trips varied from 14 to 37 days. The total distance traveled was 1 924 km. Dead animals found amounted 464 individuals, 66 of them were birds (25 identified species), 130 mammals (15 species) and 268 reptiles (18 species). The species with the highest number of individuals were the snake Leptodeira annulata (n=119), the oppossum Didelphis marsupialis (n=39) and the spectacled caiman Caiman crocodilus (n=33). Excluding domestic animals, the rate of road-killed vertebrates was 0.2282 indiv./km, a figure 28.3% higher than previous studies in the same road. Changes in the relative number of collisions for some species, respect to the numbers reported 20 years ago, were linked to the increase in traffic flow and changes in land use. Road segments with collision rates higher than expected by chance were identified. Collition by cars may be the principal cause of mortality for species like the tamandua (Tamandua tetradactyla) and the giant anteater (Myrmecophaga tridactyla), the last considered a vulnerable species. Some basic measures are proposed to reduce wildlife mortality on the road.

    Pathogenic strains of Acanthamoeba are causative agents of keratitis and encephalitis that often may end fatal in humans and other animals. In the present study, twenty-seven soil samples were collected in the Bolivar State in Venezuela and checked for the presence of Acanthamoeba. Samples were cultivated onto 2% non-nutrient agar plates seeded with a layer of heat killed E. coli. Amplification by PCR and sequencing of the DF3 region of the 18S rDNA of Acanthamoeba was carried out in order to confirm morphological identification of the amoebae. Furthermore, Acanthamoeba spp. was isolated from 51.8% of soil samples. Sequencing of the DF3 region of the 18S rDNA resulted in the identification of genotype T4 in all samples. To the best of our knowledge, this is the first report of genotype T4 in soil sources from Venezuela. Further studies should be carried out in this State and in the country in order to determine the current occurrence of Acanthamoeba in Venezuelan environments.

    Malnutrition is a public health problem for underdeveloped countries. From the 852 million of undernourished estimated by FAO between 2000 and 2002, 815 million belonged to underdeveloped countries, 28 million to countries in transition and 9 million to developed countries. Malnutrition in Venezuela had a 6% raise between 2000 and 2002, when it went from 11% to 17%. This work was done with children under 15 years old from La Escalera, using classic indicators and their combination, relating them with socioeconomic conditions, through the NBI and Graffar Méndez Castellano methods, as to consider the population nutritional profile. The higher prevalence corresponded to normal nutritional values, which oscillated between 55,7% and 80,7% in the 7-14 years old group and the 2-6 years old group, respectively. Malnutrition was found in the under 2 years old group and 7-14 years old group, with values ranging between 12,5 and 41,0% respectively. The least prevalence was found for excess malnutrition. 100% of the families in this study are poor, according to NBI; although the Graffar Mendez Castellano method established that poverty was about 60%, while 40% belonged to a medium-low status. Relating nutritional diagnosis with social stratification and the mother's educational level, three patterns were observed: III, IV and V, prevailing normal diagnosis, followed by malnutrition by deficit and malnutrition by excess, respectively. The predominating mother's educational level corresponded to incomplete high school, followed by analphabetism and the least prevalent has complete basic elementary education. It should be noted that the nutrition deficit was inversely related to the socioeconomic stratification and the mother's educational level.

    draws on this context of 'interdependent hegemony' to explore the existing relationship between Venezuela, as a swing state, and China, as one of the Big Three global powers. Particularly, I focus on Venezuelan efforts to develop, at the domestic and regional level, a counterhegemonic political project...... against the US and how China is considered a valuable ally to acquire more independence. However, this situation of interdependence can paradoxically lead to a new kind of dependence, in this case on China. To analyze these relations, I propose a conceptual framework consisting of three dimensions: 1...... of a political and economic model which can inspire or be followed by other countries. Although China's influence and increasing power in Venezuela is unquestionable in economic terms, the Venezuelan government uses its agreements with China strategically to legitimate its policies, in the name of a South...

  12. Venezuela: A petro-state using renewable energies. A contribution to the global debate about new renewable energies for electricity generation

    In spite of the economic role of oil, Venezuela has started developing hydroelectricity since the 1950s. At present, the country is trying to introduce additional renewable energy sources (RES) but still has to overcome a series of hurdles in order to deploy them. Unlike other developing countries, oil countries such as Venezuela do not lack financial means and sometimes show a tendency to solve problems by using money when other approaches could be more helpful. The main goal of this qualitative, comparative policy analysis is to find out whether the availability of oil revenues restraints or favors the adoption of RES. Based on the rentier state theory, German Massabie examines the reasons why Petro states try to dispose of their natural wealth to take advantage of non-conventional energy sources. He analyses and interprets primary and secondary data collected in Germany and in Venezuela and draws on interviews with Venezuelan experts, policy makers, and key actors. The study allows a look beyond laws, development programs, and official statements. (orig.)

    Differential identification of Entamoeba histolytica and Entamoeba dispar is essential for both appropriate patient treatment and epidemiological purposes. To determine the prevalence of these amoeba infections in Santa Rosa de Agua (Maracaibo, Zulia State, Venezuela), a PCR assay using specific primers for each species was standardized and applied. 204 stool samples were analyzed through direct microscopic examination with SSF (0.85%) and lugol, formol-ether concentration, and PCR. Under direct microscopy, 42 individuals (20.58%) presented the E. histolytica/E. dispar complex. Meanwhile PCR showed 47 positive cases for these amoebas: 22 E. histolytica (10.78%), 16 E. dispar (7.84%), and 9 (4.41%) mixed infections. There was no significant difference in the presence of E. histolytica and/or E. dispar according to either gender or age. There were no cases of these amoebas in children under 2 years of age. Observed frequency of E. histolytica (31/204) shows the endemic nature of amoeba infection in this community.

    Malaria in pregnancy constitutes a world-wide public health problem. With the objective of studying malaria in pregnancy, a cross-sectional, descriptive epidemiological study was carried out on 449 women, in mining areas of the San Isidro parish, municipality Sifontes, state of Bolívar, Venezuela, during 2005-2006. The Malaria incidence in pregnant women was 27.4%: 87% for Plasmodium vivax, 12.2% Plasmodium falciparum and 0.8% mixed infections. These infections appeared mainly during the second trimester (41.5%). Of the women studied, 71.5% presented symptoms and 26.2% had anemia. A higher proportion of abortions occurred among infected mothers with Plasmodium vivax (3/5); and there were 3.3% low-birth-weight neonates. A case of placental malaria (0.8%) for Plasmodium vivax was registered. An association was observed between mothers receiving chemoprophylaxis and the adequate weight of newborns (chi2 = 41 23gl. p < 0.0001), independently of the regularity of treatment. It is concluded that the routine administration of antimalarial quimioprophilaxis against P. vivax to pregnant women, could be justified in endemic areas. It is advisable to establish the routine diagnosis and opportune treatment during the prenatal practice in the transmission areas of malaria.

    The main vector of Chagas disease in Venezuela is Rhodnius prolixus. Specimens of Rhodnius sp., identified elsewhere as R. prolixus by molecular tools, were collected in Barinas State (Venezuela) before insecticide application, and compared by morphometric techniques with post-spraying, re-infesting insects after control. Geometric morphometry was applied, allowing separate analyses of shape and size. The idea of a single species sharing silvatic and domestic/peri-domestic ecotopes was supported, suggesting new evolutionary scenarios for the controversial R. prolixus origins. The same data allowed to understand the possible mechanisms of villages re-infestation after a control campaign, either recolonization by local recovery of survivors or re-infestation by external migrants. Both mechanisms were apparent. Although shape properties could distinguish very close subpopulations such as insects from houses and insects from peri-domestic shelters, they were unable to identify the insects from palm trees as a distinct subpopulation. This strongly suggested that human environment could receive immigrants from palm trees. The pattern of size variation supported the hypothesis of a one-way exchange from silvatic to human environments, but did not support the reverse movement. Thus, morphometric data indicated that a silvatic population of the local vector is probably responsible for re-infesting villages after insecticide application, and they also pointed to the existence of re-infestation by local recovery of survivors. According to this interpretation, new epidemiological scenarios must be considered to improve Chagas disease control in Venezuela.

    Rabies is a zoonotic viral disease and in Zulia State, it constitutes a public health problem of a high social impact, due to the report of cases in human beings. In this study, the presence of urban rabies was determined in Zulia's State and its distribution was identified according to municipalities and affected species during 1996-2006. In the scope of a descriptive study, a documented revision of Zulia's State Zoonosis Regional Coordination registries for the period in study was carried out. A total occurrence of 1.033 rabies cases was observed, 1.017 were in animals and 16 in human beings. The biggest incidences were for Maracaibo (31.40%) and San Francisco (15.68%) municipalities. The type of predominant rabies was the urban one; the principal reservoir and transmitter was the canine one (91.60%). Of the reported cases in human beings, the biggest incidence was in in Maracaibo Municipality (37.5%) and the most affected age group was <15 years (81.2%). A low percentage in the coverage of vaccination was presented (33%). A high incidence of rabies is demonstrated in Zulia's State in spite of this being a preventable immune disease. A positive correlation was determined between the number of admissions and cases (rs=0.948 P<0.01). It is necessary to implement an effective control of the sources of infection and to support a minimal coverage of vaccination of 80% in canines and furthermore, to implement community education programs, to diminish the risk of infection and the occurrence of cases.

    Large populations live on or near alluvial fans in locations such as Los Angeles, California, Salt Lake City, Utah, Denver, Colorado, and lesser known areas such as Sarno, Italy, and Vargas, Venezuela. Debris flows and flash floods occur episodically in these alluvial fan environments, and place many communities at high risk during intense and prolonged rainfall. In December 1999, rainstorms induced thousands of landslides along the Cordillera de la Costa, Vargas, Venezuela. Rainfall accumulation of 293 mm during the first 2 weeks of December was followed by an additional 911 mm of rainfall on December 14 through 16. Debris flows and floods inundated coastal communities resulting in a catastrophic death toll of as many as 30,000 people. Flash floods and debris flows caused severe property destruction on alluvial fans at the mouths of the coastal mountain drainage network. In time scales spanning thousands of years, the alluvial fans along this Caribbean coastline are dynamic zones of high geomorphic activity. Because most of the coastal zone in Vargas consists of steep mountain fronts that rise abruptly from the Caribbean Sea, the alluvial fans provide practically the only flat areas upon which to build. Rebuilding and reoccupation of these areas requires careful determination of hazard zones to avoid future loss of life and property. KEY TERMS: Debris flows, flash floods, alluvial fans, natural hazards, landslides, Venezuela

    Full Text Available In the above article author describes evolution of legal regulation of international commercial arbitration in Venezuela. Author cites statistics of arbitration centers in Venezuela activities. In past two decades many Latin American countries have reformed their arbitration law. In an effort to modernize its arbitral institutions several Latin American countries adopted Model Law on International Commercial Arbitration of the UN Commission on International Trade Law (UNCITRAL. In addition, many Latin American countries have adopted the monistic system. Author pays detailed attention to this issue, discusses concept of a monistic system - a system in which a unique set of rules governs both domestic and international arbitration. Author argues that legal system of Venezuela fits this definition. Venezuelan law on arbitration in 1998 makes no distinction between domestic and international arbitration. Arbitration was included in judicial system under the Constitution of Venezuela of the 1999. Art. 258 of the Venezuelan Constitution states that arbitration, conciliation and mediation are alternative ways of resolving disputes.

    Full Text Available INTRODUCTION:In Venezuela, acute diarrheic syndrome (ADS is a primary cause of morbi-mortality, often involving the Salmonella genus. Salmonella infections are associated with acute gastroenteritis, one of the most common alimentary intoxications, and caused by the consumption of contaminated water and food, especially meat. METHODS: Conventional and molecular methods were used to detect Salmonella strains from 330 fecal samples from individuals of different ages and both sexes with ADS. Polymerase chain reaction (PCR was used for the molecular characterization of Salmonella, using invA, sefA, and fliC genes for the identification of this genus and the serotypes Enteritidis and Typhimurium, respectively. RESULTS: The highest frequency of individuals with ADS was found in children 0-2 years old (39.4%, and the overall frequency of positive coprocultures was 76.9%. A total of 14 (4.2% strains were biochemically and immunologically identified as Salmonella enterica subsp. enterica, of which 7 were classified as belonging to the Enteritidis serotype, 4 to the Typhimurium serotype, and 3 to other serotypes. The S. enterica strains were distributed more frequently in the age groups 3-4 and 9-10 years old. CONCLUSIONS: The molecular characterization method used proved to be highly specific for the typing of S. enterica strains using DNA extracted from both the isolated colonies and selective enrichment broths directly inoculated with fecal samples, thus representing a complementary tool for the detection and identification of ADS-causing bacteria.

    Full Text Available Com base na grande incidência da espécie invasora de caramujo africano, Achatina fulica, na cidade de Araguaína, objetivamos investigar a relação existente entre as condições microbiológicas do caramujo e a ocorrência deste nas hortas domésticas na cidade. Foram seguidas metodologias laboratoriais na determinação de presença/ausência de microrganismos na superfície do caramujo, assim como de fungos filamentosos. Para complementar o trabalho foram entrevistados cento e um (101 moradores domiciliados em dezenove setores de Araguaína. Os resultados microbiológicos da superfície do caramujo apresentam valores acima de 1,2x105 UFC/g de bactérias heterotróficas, foram também isolados fungos dos gêneros Aspergillus, Penicillum, Trichophyton e Cryptococcus. No levantamento por entrevista, 86% dos entrevistados relataram uma alta incidência do caramujo nos seus domicílios no período chuvoso e 50% deles afirmaram ter algum tipo de canteiro em casa, porém 85% desconhecem as doenças que poderiam ser transmitidas por este caramujo. Concluímos que existe uma elevada contaminação microbiológica na superfície dos caramujos analisados, o que combinado com a preferencia pelos produtos de hortas domesticas desconhecendo os riscos que a invasão por caramujos pode acarretar, indicam a necessidade de ampliar o conhecimento sobre a determinação das condições de risco inerentes a A. fulica, assim como sua divulgação na sociedade araguaínense sobre seus efeitos, não somente na saúde das pessoas mas também na produtividade da agricultura artesanal.

    Immigration to Venezuela is examined using census data with the focus on the period 1971-1981. A brief overview of trends since the beginning of the twentieth century is first presented. The analysis indicates that "immigration to Venezuela is clearly of a short-term nature. Flows follow job opportunities and adjust to the labour market and to the financial capacity of the exchange market. The large increase of migratory movements to Venezuela in the 1970's is characterized by a diversification of their places of origin and by a greater instability. To a large extent, the migrants are illegal, especially those coming from Colombia and the Caribbean islands. Because of the crisis of the early 1980's, which is now worsened by the down trend of both oil prices and the U.S. dollar, Venezuela has become less attractive to immigrants, particularly from neighbouring countries." The authors observe that migrants in Venezuela are not well integrated and may depart, disrupting the labor supply in certain technical and specialized occupations (SUMMARY IN ENG AND SPA)

    Bacterial resistance to mercury (Hg) was investigated in strains isolated from Hg-contaminated tailing ponds located in the gold mining area of El Callao (Bolívar State, Venezuela). High frequencies of resistance were detected to both inorganic-Hg and organomercurials among these strains. A broad range of resistance levels was observed when determining minimal inhibitory concentrations of Hg(2+). Some strains were able to grow in liquid medium containing 25 muM: Hg(2+), whereas others grew at 300 muM: Hg(2+). Of 190 Hg-resistant strains tested, 58.2% were additionally shown to be resistant to ampicillin (40 mg/L), 33.3% to chloramphenicol (30 mg/L), 24.9% to streptomycin (30 mg/L), 23.3% to tetracycline (30 mg/L), and 1.6% to kanamycin (30 mg/L). Furthermore, we found that 20% of the Hg-resistant strains were simultaneously resistant to as many as four of these antibiotics, at the concentrations tested. The presence of large plasmids in 62.9% of 53 Hg-resistant strains screened prompted us to investigate the horizontal transfer of resistance determinants. Mating experiments were performed using Escherichia coli and Pseudomonas aeruginosa as recipient strains. The results obtained confirmed that indigenous Hg-resistant bacteria colonizing the tailing ponds can effectively transfer the phenotype to potentially pathogenic species.

    Full Text Available This study examined the seasonal variation of avifaunal composition and structural community in foothill gallery forest fragments in the Manzanares river medium basin, state of Sucre, Venezuela, at two sectors: Guaranache-Cancamure (GC y Tataracual-Cangrejal (TC, during february-may (dry period and june-november (rainy period. Birds samples were taken monthly by point counts and mist-nets. Correlation analysis and non parametric tests were estimated to examine differences among seasonal periods. 73 species were recorded and were grouped into 7 feeding guilds. Mean diversity of both periods was high but no significant; although dry period diversity was moderately higher than rainy period. Richness and diversity showed no significant differences among periods, neither showed significant correlation with rainy levels. Occurrence frequency showed unusual > eventual > habitual > prevalent species pattern. Complementary index showed a substantial mean similarity monthly (67%. For both methods species cumulative curves displayed similar growing patterns. Insectivores and frugivores-insectivores were the most diverse feeding guilds. Amazilia tobaci obtained the highest specific importance index. Pitangus sulphuratus was the most persistent species. Community dynamic of avifauna of these riparian landscape would seem be influenced primarily to a suitable resources availability because to vertical and horizontal floristic heterogeneity. Conservation plans for medium basin of Manzanares river should take into account regular deforestation activities, particularly periodic and uncontrolled burnings, which likely would affect more adversely species associated with understory habitats.

    The mineral phosphate-solubilizing (MPS) activity of a Pantoea agglomerans strain, namely MMB051, isolated from an iron-rich, acidic soil near Ciudad Piar (Bolívar State, Venezuela), was characterized on a chemically defined medium (NBRIP). Various insoluble inorganic phosphates, including tri-calcium phosphate [Ca(3)(PO(4))(2)], iron phosphate (FePO(4)), aluminum phosphate (AlPO(4)), and Rock Phosphate (RP) were tested as sole sources of P for bacterial growth. Solubilization of Ca(3)(PO(4))(2) was very efficient and depended on acidification of the external milieu when MMB051 cells were grown in the presence of glucose. This was also the case when RP was used as the sole P source. On the other hand, the solubilization efficiency toward more insoluble mineral phosphates (FePO(4) and AlPO(4)) was shown to be very low. Even though gluconic acid (GA) was detected on culture supernatants of strain MMB051, a consequence of the direct oxidation pathway of glucose, inorganic-P solubilization seemed also to be related to other processes dependent on active cell growth. Among these, proton release by ammonium (NH(4)(+) ) fixation appeared to be of paramount importance to explain inorganic-P solubilization mediated by strain MMB051. On the contrary, the presence of nitrate (NO(3)(-) ) salts as the sole N source affected negatively the ability of MMB051 cells to solubilize inorganic P.

    2007-07-01

    Venezuela is an important player in the energy world, because of its hydrocarbons reserves. The process for calculating oil and associated gas reserves is described bearing in mind that 90% of the gas reserves of Venezuela are associated to oil. Likewise, an analysis is made of the oil reserves figures from 1975 to 2003. Reference is also made to inconsistencies found by international experts and the explanations offered in this respect by the Ministry of Energy and Petroleum (MENPET) and Petroleos de Venezuela (PDVSA) regarding the changes that took place in the 1980s. In turn, Hubbert's Law is explained to determine peak production of conventional oil that a reservoir or field will reach, as well as its relationship with remaining reserves. Emphasis is placed on the interest of the United Nations on this topic. The reserves of associated gas are presented along with their relationship with the different crude oils that are produced and with injected gas, as well as with respect to the possible changes that would take place in the latter if oil reserves are revised. Some recommendations are submitted so that the MENPET starts preparing the pertinent policies ruling reserves. (auth)

    This study aimed to estimate the prevalence of musculoskeletal disorders and rheumatic diseases in the Warao, Kari'ña, and Chaima indigenous populations of Monagas State, Venezuela. A cross-sectional, analytical, community-based study was conducted in 1537 indigenous subjects ≥18 years old (38.6 % male, mean age 41.4 ± 17.5 years). The cross-culturally validated Community Oriented Program for the Control of Rheumatic Diseases (COPCORD) diagnostic questionnaire was applied. Subjects with a positive COPCORD diagnosis (either historic or current pain) were evaluated by primary care physicians and rheumatologists. A descriptive analysis was performed and comparisons made using analysis of variance and the chi-square test. Pain in the last 7 days was reported by 32.9 %, with pain intensity, according to a Likert-type scale [no pain, 195 (38.5 %); minimal pain, 231 (45.6 %); strong pain, 68 (13.4 %); intense pain, 5 (0.9 %)], 38.0 % reported historical pain, and 641 (41.7 %) had either historic or current pain. Of the COPCORD-positive subjects, pain most frequently occurred in the knee, back, and hands. Musculoskeletal and rheumatic diseases included osteoarthritis (14.1 %), back pain (12.4 %), rheumatic regional pain syndromes (RRPS) (9.7 %), undifferentiated arthritis (1.5 %), rheumatoid arthritis (1.1 %), and fibromyalgia (0.5 %). Chaima (18.3 %) and Kari'ña (15.6 %) subjects had a high prevalence of osteoarthritis, and Warao subjects had a high prevalence of low back pain (13.8 %). The prevalence of RRPS was high in all three ethnic groups. The Chaima group had the highest prevalence of rheumatic diseases, with 2.0 % having rheumatoid arthritis. This study provides useful information for health care policy-making in indigenous communities.

    Here we undertook an inorganic geochemical study of Cenomanian-Campanian bedded cherts (the Táchira Ftanita Member of the La Luna Formation) in the western region of the Táchira State, Venezuela. The aim of this study was to determine the paleo-oceanographic and paleo-environmental conditions that governed the deposition of chert beds and put forward a sedimentation model for the Táchira Ftanita Member in the study area. Seventy-two chert samples were collected and trace/rare earth elements (La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Rb, Cs, Th, U, Y, Co, and Sc) and major/trace elements (SiO2, TiO2, Al2O3, Fe2O3, MgO, CaO, Na2O, K2O, P2O5, Mn, Ba, Sr, Cr, Ni, and V) were determined by ICP-MS and ICP-OES, respectively. On the basis of the stratigraphic abundance and distribution of relatively immobile elements, as well as the distribution of rare earth elements, we established that the detrital sediments associated with the sequences studied have matching characteristics with distinct continental materials, with an intermediate composition, thus pointing to the Guayana Massif as the main source of sediments. In addition, we also determined the influence of hydrothermal input on the chemical composition of some cherts from La Molina Mine. On the basis of geochemistry, we found a biological influence regarding the uptake of dissolved silica for forming chert beds. The application of parameters for relatively immobile elements allowed us to establish a still proximal continental-margin (hemipelagic) for most samples from the Zorca River and a continental-margin for almost all the cherts from the Delicias-Villa Páez section and the remaining samples from La Molina Mine. Finally, we propose that the rhythmicity that accompanies the sequence of bedded cherts is related to changes in the intensity of upwelling patterns of water and/or to variability in the supply of silica dissolved in the Táchira sub-basin.

    In order to analyze the frequency, injury rate and cause of on site accidents to the hands of workers on the east coast of lake of Maracaibo in Zulia State, data was obtained from the accident reports registered with the Venezuelan Institute of Social Security. An occupational hand injury was defined as a traumatic injury to the hands, fingers or wrists that occurred while the employee was at work; that resulted from a single exposure to a hazardous agent. The following variables were analyzed: age, severity, economic activity, material agent, mechanic cause, type of injury, type of accident and unsafe action. The frequency rate was used to analyze the annual accident rate. During the period under study 2.456 injuries to the hand were registered, representing 36% of the total injuries reported; 95% were light injuries, 5% incapacitating and two cases resulted in the death of the worker. 72% of the injuries were located in the fingers, 22% in the hands and 6% in the wrists. The greatest frequency of injuries were found in the economic activity in mines and quarries with a rate of 123.1 per thousand. The age group most affected was of 20-29 years (42%), Wounds or contusions and crushings were the injuries most commonly reported, in 39% and 36% of the cases respectively. The main type of injuries were caused by run over, running into or blow from objects. The principal agents causing injuries were materials, substances and radiations in 45% of the cases. It is concluded that the hand injury rate is very high in the exploitation of mines and quarries and represents the main cause of worker's disability.

    The author describes the decline of Venezuela's oil industry as well as President Chavez' reaction to Venezuela's budgetary crisis. Politicization, falling investment and the obligation to take upon itself a plethora of social spending have left national oil company Petroleos de Venezuela, S.A. unable to produce efficiently and maintain production levels. Falling oil production and lower oil prices have in turn left president Hugo Chavez unable to spread the wealth to Venezuela's poor and he is searching desperately for ways to extract yet more from Venezuela's dysfunctional economy. As funds run out, Venezuela's expensive foreign policy, supporting regional allies, in particular Cuba, and seeking to export anywhere but the United States, proves overly expensive. Venezuela's impoverished masses, still supportive of Chavez during February's elections, may become less so as funds for social programmes run out. For Chavez it is a time for making choices... otherwise the people of Venezuela will choose for him. [Dutch] De auteur beschrijft de teruggang van de olie-industrie van Venezuela en de reacties van president Chavez op de budgettaire crisis in Venezuela.

    Interest for apheresis activity has been growing in Venezuela. In 1976 there were only a few devices; in 2003, 80 apheresis machines performed 27,675 donor apheresis procedures and 547 therapeutic procedures countrywide. We report the activity at the Metropolitan Blood Bank (the largest one of the country) in the period 1999-2003: 597 therapeutic procedures were performed in 171 patients, during 212 crisis episodes. The average age was 38 +/- 16 years, 65% male and 35% female. Most of the therapeutic procedures were therapeutic plasma exchange for hematology diseases (mainly thrombotic thrombocitopenic purpura and hemophilia inhibitors), including 184 therapeutic procedures with the Autopheresis-C (Baxter Healthcare Corp., Deerfield, IL). Most common adverse effects (3.9%) were hypotension and allergic reactions to the plasma.

    Sources of demographic data for Venezuela include 11 population censuses conducted between 1873-1981, birth and death registration statistics, and the household sample survey. The average annual rate of population growth increase from 2.8% between 1920-40 to 3-4% thereafter. The population at the 1961 census was 7.52 million. According to preliminary data from the 1981 census, the population of 14.57 million is growing at an annual rate of 2.8%. 41.2% of the population is under 15 years old, implying a huge demand for educational and health services, housing and employment. The dependency rate in 1980 was 81.3% for the country as a whole, 100.4% in rural areas, and 76.0% in urban areas. The young age structure means that the population will continue to grow even if natality rates decline. The crude natality rate was estimated at 47.3/1000 for 1950-55, 36.0 for 1970-75, and 32.9 for 1980-85. Some rural areas still have natality rates of over 47/1000. The total fertility rate declined from 6.5 in 1950-55 to 4.1 in 1980-85. The decline in the natality rate reflects improving quality of life, availability of family planning services, urbanization, and access of women to productive activities and educational centers. The mortality rate was 12.3/1000 in 1950-55, 9.1 in 1960-65, in 1970-75, and has been estimated at 5.5 for 1980-85. Some rural areas have mortality rates of 8.1. The infant mortality rate was 50.2/1000 in 1971 and 34.3 in 1980. Life expectancy at birth is about 69 years. During the 1920s, Venezuela unerwent expansion in infrastructure and technological utilization, generating rapid urbanization. 39.2% of the population was urban in 1941, compared to 78.8% in 1980. The significance of urbanization in Venezuela is due to the rapidity as well as the diffusion of the process. The household sample survey for the 2nd half of 1980 indicated a total of 8.16 million employed and an activity rate of 32.1% overall, 46.4% for males and 17.7% for females. The

    Full Text Available Scorpion poisoning was surveyed in Acosta and Caripe counties, located in the Turimiquire subregion of Monagas State, Venezuela, aiming to expand information on stings by characterizing some epidemiological aspects. From 1987 to 1993, 298 cases of scorpion stings were recorded in Acosta and Caripe counties. Acosta had 212 cases, with an annual incidence rate of 18.3‰(cases per 10,000 inhabitants and a period median incidence rate of 128‰. The scorpion poisoning index is 4.18 times greater in Acosta than in Caripe, confirming the former as a hyperendemic zone for this type of injury, with a phenomenon of cyclical temporal fluctuations and an upward trend. This area is infested with scorpions of the genus Tityus. Our results show that the region surveyed in Monagas State is endemic for scorpion stings, posing a major public health problem.No presente trabalho os autores procuram mostrar o perfil epidemiológico do escorpionismo nos Municípios Acosta e Caripe, localizados na subregião geográfica do maciço montanhoso do Turimiquire do Estado de Monagas, Venezuela. Durante o período de 1987 a 1993, registrou-se um total de 298 acidentes causados por escorpiões, correspondendo 212 ao Município de Acosta e 86 ao de Caripe. Acosta apresentou um índice de incidência anual de 18,3 casos por 10.000 habitantes e 128% para o período meio de estudo; o índice de escorpionismo foi 4,18 vezes maior que o apresentado em Caripe. Os dados indicam que o Município de Acosta é hiperendêmico para este acidente, com um comportamento variável e uma tendência ao incremento ao longo dos anos. Os resultados obtidos evidenciam que estas regiões do Estado de Monagas são endêmicas para o acidente peçonhento causado por escorpiões que assumem importância como problema de saúde pública, mais ainda quando são áreas de dispersão do gênero Tityus.

    Full Text Available O objeto principal deste estudo é verificar quais as características que levam os comportamentos motivacionais de seleção de lojas e formatos de varejo de alimentos por parte do consumidor de baixa renda da cidade de Araguaína Tocantins. Neste estudo observou-se que as técnicas qualitativas de investigação apontam características do consumidor de baixa renda bem como o comportamento das empresas varejistas de alimentos quanto ao posicionando frente a esse consumidor. Os pontos principais deste estudo levam em conta de que no ato da compra a loja pode proporcionar ao consumidor uma experiência extremamente agradável, desde que se crie todo um ambiente agradável que passe uma boa imagem e proporcione certo calor humano, de prazer e aceitação. Por isso, o atendimento e o trabalho de visual merchandising são extremamente importantes na construção de valor. Os resultados revelam que o preço dos produtos nem sempre é importante para os consumidores, o que é comprovado pela preferência dos consumidores na região de estudo pelo supermercado que pratica os maiores preços, mas que com eficiência desenvolve um trabalho exaustivo e sinérgico nos outros produtos do mix de marketing.

    Full Text Available The focus of this article is on what role, if any, oil has on Venezuela's instability. When trying to explain why a resource-rich country experiences slow or negative growth, experts often point to the resource curse. The following pages explore the traditional theory behind the resource curse as well as alternative perspectives to this theory such as ownership structure and the correlation between oil prices and democracy. This article also explores the various forms of instability within Venezuela and their causes. Finally, the article looks at President Hugo Chavez's political and economic policies as well as the stagnation of the state oil company, Petroleos de Venezuela (PDVSA. This article dispels the myth that the resource curse is the source of destabilization in many resource dependent countries. Rather than a cause of instability, this phenomenon is a symptom of a much larger problem that is largely structural.

    Full Text Available El diseño e implantación de políticas públicas expresas en el área del transporte urbano en Venezuela data de finales de los años ochenta. En él se contempló la “modernización” y la “municipalización” del transporte urbano. El objetivo del presente trabajo es analizar la intervención de los poderes locales en el diseño e implementación de la política de transporte urbano en las ciudades venezolanas. La metodología utilizada consistió en el análisis de información documental y entrevistas semiestructuradas a funcionarios de Alcaldías y del gobierno central. Los resultados indican que la política fue diseñada en el seno del Ministerio de Transporte y Comunicaciones y del Ministerio de Infraestructura, por un grupo de especialistas, siguiendo lineamientos de la banca multilateral, sin consultar a los actores del sistema, y muy especialmente a los Municipios o Alcaldías. Se concluye que los poderes locales han intervenido de forma limitada en la implantación de la política, con muy escaso poder de decisión y siguiendo lo establecido por el gobierno nacional.

Se abordó la investigación enmarcada en una metodología de tipo positivista con técnicas estadísticas. Se concluyó que los recursos escasos y las dificultades históricas exigen un incremento de esfuerzos presupuestarios y de gestión, en cantidad, calidad y transparencia por parte del Estado a través del gasto público.

    Full Text Available Insulin Resistance (IR is an important finding in several diseases including diabetes and metabolic syndrome, and its diagnosis seems pertinent during the evaluation of insulin sensitivity, though mathematical models like HOMA (Homeostasis Model Assessment. The purpose of the present study was to determine an appropriate cutpoint for HOMA-IR in adult individuals from the Maracaibo municipality, Zulia state, Venezuela. Two-thousand and twenty-six individuals from both sexes and beyond 18 years of age were selected from the Maracaibo city Metabolic Syndrome Prevalence Study, a descriptive cross-sectional study with multietapic sampling. HOMA-IR was calculated using the formula [Fasting Insulin (µU/L x Fasting Glycemia (mmol/L/22,5]. To estimate the cutpoint, 602 healthy individuals were selected and a percentile distribution was calculates, alongside ROC Curve in order to identify the best cutoff point according to sensitivity and specificity. Overall, the average HOMA-IR was 3,71±3,01, with 3,65±2,96 for women and 3,76±3,06 for men (p=0,397. Using the reference population, the resulting arithmetic value was 2,64±1,67. When distributing per percentile, p75 was 3,02. When selecting a cutpoint using ROC Curve, the chosen cutoff point was 3.03 with an Area Under the Curve of 0.814 (75,2% sensitivity and 75,6% specificity. The obtained results are good enough to propose a cutpoint of 3,00 for HOMA-IR, which can be use in the clinical evaluation of IR in adults from our population

    In recent years, in addition to American cutaneous leishmaniasis (ACL), a significant number of cases of American visceral leishmaniasis (AVL) have been reported in periurban areas of Barcelona city (Anzoátegui State, Venezuela). We studied the bionomics of Lutzomyia (Lutzomyia) evansi and Lutzomyia (Psychodopygus) panamensis, possible vectors of AVL and ACL, respectively, in El Rincón, a periurban village of that city. To evaluate the seasonal domiciliary landing/biting activity of sandflies on human bait, a house was chosen in El Rincón. Landing catches were carried out between 18:00 and 06:00, once a month for a year. The results show the presence of 2 species, Lu. (Lu.) evansi (89.9%) and Lu. (Psy.) panamensis (10.1%). Lu. evansi was most abundant in the months of October and July, associated with the bimodal cycle of annual rainfall in the area. Maximum landing/biting activity of Lu. evansi was observed at 24:00 and 03:00. These findings suggest that at this time of the year and at these hours there is heightened risk of the transmission of AVL. Lu. panamensis monthly abundance also shows a direct association with rainfall and maximum landing/biting activity was observed between 02:00 and 03:00. The lower domiciliary abundance of Lu. panamensis suggests its greater importance in the extradomiciliary transmission of ACL.

    This map is one of a series of 1:500,000-scale maps that, along with several other products, stems from a cooperative agreement between the U.S. Geological Survey (USGS) and the Corporacion Venezolana de Guayana, Tecnica Minera, C.A. (TECMIN), a Venezuelan Government-owned mining and mineral exploration company. The agreement covered cooperative work carried out in the Precambrian Shield of southern Venezuela during 1987-1991 and included a geologic and mineral resource inventory, technology transfer, and scientific training (Wynn and others, in press). The Precambrian Guayana Shield (Escudo de Guyana, not to be confused with the neighboring country of Guyana) includes some of the oldest known rocks in the world (Mendoza, 1977) and also covers parts of neighboring Guyana, Surinam, French Guiana, Columbia, and Brazil. In Venezuela, it underlies most of Bolivar state and all of the Amazonas Federal Territory (see index map).

    The Neotropical fauna of saucer bugs (Naucoridae) currently includes four monotypic genera. Recent extensive collecting in Venezuela has produced three new species in two of these genera. In addition, undetermined Guyanan specimens of one of the new species were found in the United States National Museum of Natural History. Thus, described here are Placomerus obscuratus n. sp. from Guyana and Venezuela with brachypterous and macropterous hindwing forms, and two species of Procryphocricos from Venezuela. Procryphocricos quiu n. sp. is described from the brachypterous forewing form and Procryphocricos macoita n. sp. from both brachypterous and macropterous forms. Previously described species also are discussed.

    It is study the feasibility of development of the alternative energies, AE, in Venezuela based on its potential of exploitation, the analysis of its energetic system, and the attitude of the State before the AE. The results indicate that the country has a high potential of AE, that the hidroenergy in great scale is the unique one with an important participation in the energy system, and that the solar energy and the eolic are those of greater possibility of development. However, an assembly of factors impede the development in firm of the AE, fundamentally related to its historic condition of producer and consumer of fuel fossil in great scale at low cost. It is concluded that only with a change of attitude of the State and the concourse of all the actors involved in the sector, the {sup c}lean energies{sup w}ould be able to have an important weight in the national energetic balance.

    2013-01-01

    Full Text Available Discussions of democracy in contemporary Venezuela lack a settled definition of the subject, how to study it, or indeed of what counts as «democracy» in the first place. The regime has been described as everything from participatory democracy, hybrid, mixed, and personalist to populist, illiberal, or no longer democratic but rather competitive authoritarian. The goal of this article is to measure the quality of democracy in Venezuela, within the terms of a procedural concept of democracy as detailed in our earlier work. Empirical measurement of the quality of democracy on five dimensions (electoral choice, participation, responsiveness, accountability, sovereignty reveals a low level overall and deep institutional weakness under a personalist leadership, with little change from 2005 to 2010. Future scenarios, after the 2012 presidential election result, include reinforcement of authoritarian trends, open militarization, liberalization and institutional strengthening, or long term volatility and polarized conflict. All scenarios are contingent on the health of President Chávez, who is a central unifying factor for his movement and regime

    Full Text Available OBJECTIVE: To describe the epidemiological and clinical characteristics of Venezuelan pediatric patients with multiple sclerosis (MS. METHODS: Database records from the National Program for MS were searched for patients with an established diagnosis of MS whose first symptoms appeared before age 18. RESULTS: The national database held records of 1.710 patients; 3.8% had onset of the first symptoms before age 18. 46.7% were boys, yielding an F:M ratio of 1.13:1. Many children had a disease onset characterized by motor impairment (30.7%, brainstem/cerebellum and spinal cord affectation (27.6%, headache (26%. Less frequent symptoms were sensory symptoms (8% and optic neuritis (7%. DISCUSSION: Pediatric MS patients in Venezuela represent a significant proportion of all MS cases. The clinical pattern is characterized by motor symptoms at onset, and predominantly monosymptomatic presentation with a relapsing-remitting pattern. This is the first systematic attempt to estimate the prevalence of pediatric MS in Venezuela.

    Full Text Available Based on LANDSAT ETM and Digital Elevation Model (DEM data derived by the Shuttle Radar Topography Mission (SRTM, 2000 of the coastal areas of Northern Venezuela were investigated in order to detect traces of earlier tsunami events. Digital image processing methods used to enhance LANDSAT ETM imageries and to produce morphometric maps (such as hillshade, slope, minimum and maximum curvature maps based on the SRTM DEM data contribute to the detection of morphologic traces that might be related to catastrophic tsunami events. These maps combined with various geodata such as seismotectonic data in a GIS environment allow the delineation of coastal regions with potential tsunami risk. The LANDSAT ETM imageries merged with digitally processed and enhanced SRTM data clearly indicate areas that might be prone by flooding in case of catastrophic tsunami events.

    At the Venezuela National Astronomical Observatory we are carrying out variability surveys spanning many hundreds of square degrees near the celestial equator, using an 8k x 8k CCD Mosaic Camera optimized for drift-scanning on a 1m Schmidt telescope. Among the initial efforts was a project to obtain the first moderately deep, homogeneous sample of young stars over an area of ~180sqr.deg. encompassing the entire Orion OB1 association, one of the nearest and most active regions of star formation. The results show that variability is a powerful technique to identify pre-main sequence populations, specially in sparse areas devoid of gas and dust. We are currently developing a massive database, equipped with web-based data mining tools, that will make our data and results available to the astronomical community.

Morphological characterization allowed its assignment to the Tityus bahiensis population inhabiting the southernmost area of the species' geographic range, e.g. the state of São Paulo in Brazil, northern Argentina and Paraguay. The fact that the only available Venezuelan antiscorpion (anti-Tityus discrepans serum does not neutralize the effects of alpha- and beta-toxin from Tityus serrulatus venom (which resembles in composition that of T. bahiensis constitutes a warning to local clinicians confronted with envenomations by noxious species transported to Venezuela from Brazil by human agency.

O objetivo deste trabalho é apresentar alguns aspectos do processo de deslocamentos transfronteiriços no norte do Brasil, no município de Pacaraima (Estado de Roraima e na fronteira sul da Venezuela, no município de Gran Sabana (Estado Bolívar, e, ao mesmo tempo, apontar as tendências e reflexos nas configurações socioculturais nessas zonas de contato. Nessa fronteira Brasil-Venezuela, podemos afirmar que o trânsito maior é de brasileiros para a Venezuela e para a Guiana, em decorrência das possibilidades de atuarem nas atividades de mineração, no comércio local e no setor de transportes, além das atividades ilegais, como tráfico de mulheres, contrabando de combustível e câmbio ilegal de moeda. Apresenta-se, no entanto, uma nova tendência que é a imigração de estrangeiros de outros países do continente, tais como peruanos e colombianos. Esses migrantes transfronteiriços percorrem os países fronteiriços em itinerários cuja porta de entrada é a Venezuela e a Guiana, mas também o Estado do Amazonas.BORDER zones are zones of cultural lending, borrowing and appropriation, and, therefore, a privileged vantage point for understanding the phenomenon of international migration.

    Full Text Available Con el objetivo de contribuir a discernir la compleja problemática de la pobreza y de sus posibles salidas, en este trabajo se discuten algunas razones que explicarían la continuidad del estilo asistencial compensatorio focalizado, propio de la política social neoliberal, en la actual estrategia venezolana de atención a la pobreza, pese a que el discurso del presente gobierno se opone frontalmente a dicho modelo. Destacan, entre otros, dos factores básicos: 1 la vigencia de los mecanismos psicológicos del rentismo, manifiesto en la cultura clientelar aún internalizada en el venezolano, tanto en los ciudadanos como en los gobernantes, a pesar de los cambios de la coyuntura económica y sociopolítica del país, y 2 la importancia político-estratégica del asistencialismo en función del objetivo prioritario, no declarado, de mantener una relativa paz social, legitimidad política, estabilidad del gobierno y del régimen democrático. Se señalan riesgos potenciales del asistencialismo y se bosquejan algunos de los prerrequisitos que hoy exige el enfrentamiento a la pobreza en Venezuela.

The siting of this hall was carefully studied, and such factors as nearness to industrial zones, climate, and ease of access were decisive aspects that were taken into account. The final choice was a site near Morón, in the Carabobo Department, close to the sea. The main constructional item is the roof of the large hall. It is made of a series of hyperbolic-parabolic reinforced concrete thin shells, of rectangular planform, and slightly inclined towards the north, to produce a saw edge profile. Each of these shells is supported by a central column. The hollow spaces along the saw edge profile have been used for ventilation. The enclosing walls consist of trellice material, which also provide ample facility for additional ventilation.Para el montaje de los coches Volkswagen destinados al mercado venezolano, se ha construido una gran nave dotada de todos los servicios necesarios: pintura, engrases, aparcamiento de los vehículos terminados, etc. La elección del lugar más apropiado para la situación de la nave y edificios anexos fue motivo de un detenido estudio, en el que la proximidad a zonas industriales, clima, fácil entrada de materiales procedentes de ultramar y salida para los acabados, fueron los factores decisivos. Definitivamente se eligió un solar en las cercanías de Morón, del departamento de Carabobo, y próximo al mar. Lo más notable es la cubierta de la gran nave, formada por una serie de láminas parabólico-hiperbólicas de hormigón armado, de planta rectangular, inclinadas ligeramente hacia el norte para formar un perfil en diente de sierra.

    1996-12-31

    The Government of Venezuela ratified the United Nations Framework Convention on Climate Change (UNFCCC) in December, 1994. The Convention requires all parties to develop and publish national inventories of anthropogenic greenhouse gas emissions (GHG) as well as national plans to reduce or control emissions, taking into account their common but differentiated responsibilities and their specific national and regional development priorities, objectives, and circumstances. Within this context, the Ministry of Environment and Renewable Natural Resources and the Ministry of Energy and Mines developed the `Venezuelan Case-Study to Address Climate Change`. The study was initiated in October 1993, with the financial and technical assistance of the Government of United States, through the U.S. Country Studies Program (USCSP), and the Global Environment Facility (GEF), through the United Nations Environment Programme (UNEP).

Anti-HCV antibodies were determined using a fourth generation ELISA (Innotest HCV Ab IV kit and positive blood samples were tested using a recombinant assay kit (Inno-LIA HCV Ab III, both kits from Innogenetics N.V., Belgium. The findings indicate a lack of HCV seroconversion in the hemodialysis patients over the study period, confirmed by the recombinant assay. Risk factors for HCV infection were 0.3270 (95% confidence interval: 0.01323-8.080 in patients undergoing hemodialysis. The findings suggest a lack of significant sources for HCV infection due to the preventive measures to avoid its transmission in the hemodialysis unit.

Results. 27.5% of individuals had low levels of Apo A-I, 45.2% high Apo B and 60.6% high Apo B/Apo A-I ratio. Serum levels of apolipoproteins and Apo B/Apo A-I ratio did not vary with age or gender, while the ratio HDL cholesterol/Apo A-I decreased with the age. Obese individuals, smokers, hypertensive, hypercholesterolemics, hypertriglyceridemics or with low HDL cholesterol showed higher Apo B and Apo B/Apo A-I ratio. Older individuals, smokers or individuals with increased LDL cholesterol and triglycerides showed lower HDL cholesterol/Apo A-I ratio. Consumption of three or more alcoholic drinks/day was associated with decreased Apo B. Conclusions. These results show high prevalence of altered apolipoprotein profile, which is associated with major cardiovascular risk factors. The results support the inclusion of the evaluated apolipoproteins in laboratory determinations made in public health centers in Venezuela.

    2015-10-01

    In 2010, an outbreak of febrile illness with arthralgic manifestations was detected at La Estación village, Portuguesa State, Venezuela. The etiologic agent was determined to be Mayaro virus (MAYV), a reemerging South American alphavirus. A total of 77 cases was reported and 19 were confirmed as seropositive. MAYV was isolated from acute-phase serum samples from 6 symptomatic patients. We sequenced 27 complete genomes representing the full spectrum of MAYV genetic diversity, which facilitated detection of a new genotype, designated N. Phylogenetic analysis of genomic sequences indicated that etiologic strains from Venezuela belong to genotype D. Results indicate that MAYV is highly conserved genetically, showing ≈17% nucleotide divergence across all 3 genotypes and 4% among genotype D strains in the most variable genes. Coalescent analyses suggested genotypes D and L diverged ≈150 years ago and genotype diverged N ≈250 years ago. This virus commonly infects persons residing near enzootic transmission foci because of anthropogenic incursions.

    Full Text Available This paper addresses the process of decentralization in Venezuela, under mayors’ perspective, elected for the period 2000-2004. Our main goal is to identify the vision they have over such an important process that theoretically strengthens, supports, and enhances the democratic system. We contrast decentralization theory (which states that if there is not democracy at levels of government closer to the citizens-municipal government-democracy is not sustained over real bases with what Venezuelan mayors exposed about the facts observed in the nation in this sense. Our hypothesis is that the concepts and visions that the mayors expressed must coincide with the theory sustaining decentralization in general and particularly decentralization in Venezuela, which must coincide with their praxis in their municipalities. We concluded that the positive perspectives and visions as the negatives or pessimistic ones stated by the interviewed mayors coincided with theory supporting decentralization in different countries and with the evaluations of decentralization that have been conducted in different nations. Venezuelan decentralization process is not different from those that have been discovered in other countries in this sense. It seems to be that the decentralization policy in Venezuela enjoys the same virtues and suffers the same problems that decentralization policies in other countries.

    Figures of Colombian immigrants in Venezuela in the period 1981-1986 as well as the development of their socio-demographic profile and their integration into the labor market are analyzed by means of ad hoc tables drawn from a Sample Home Survey by the Oficina Central de Estadisticas e Informatica and information from the civil record office. It is estimated that in 1987 there are only half a million Colombians in Venezuela and, contrary to what is generally assumed, not only has the afflux decreased (3/4 of the Colombians entered before 1981), but also a return migration can be observed. Colombian immigration is not homogeneous, but is made up of different groups as far as their professional skills and occupations are concerned. The number of Colombians engaged in household service and those living in rural areas has decreased, but not the number of active farm workers. A greater proportion of Colombians engaged in trade and sales activities is observed, but artisans and skilled labor are still the majority.

    Current health conditions of Venezuela, together with the tropical proliferation of different types of Aedes (aegypti and albopictus), suggest the arrival to this country of ZIKA virus (ZIKV). The Pan American Health Organization urges Latin American countries to take measures to prevent the ZIKV entry and advises that these measures must be designed to detect the introduction of ZIKV in an area, track its spread and actively monitor the disease. In Venezuela and other Latin-American countries, where endemicity is high for other arboviruses such as dengue arid chikungunya, health authorities should strengthen their surveillance systems to detect early and timely introduction of ZIKV ap.d refine diagnostic methods to confirm the infection rate; however, the high incidence of cases due those viral agents reflects weakened and poorly timed insensitive monitoring systems, as well as, poor vector control measures, arising the questions: will this arbovirus pop in our country, will it set as the other as edemicepidemic and lead to alter their clinical behavior and severity of the disease?

    This paper describes the Venezuelan health system, including its structure and coverage, financial sources, human and material resources and its stewardship functions. This system comprises a public and a private sector. The public sector includes the Ministry of Popular Power for Health (MS) and several social security institutions, salient among them the Venezuelan Institute for Social Security (IVSS). The MH is financed with federal, state and county contributions. The IVSS is financed with employer, employee and government contributions. These two agencies provide services in their own facilities. The private sector includes providers offering services on an out-of-pocket basis and private insurance companies. The Venezuelan health system is undergoing a process of reform since the adoption of the 1999 Constitution which calls for the establishment of a national public health system. The reform process is now headed by the Barrio Adentro program.

We will be publishing a Spanish translation this month in Medicina Social. We present here the abstract of the article. We encourage readers to read the English original which is available at: www.medicc.org/mediccreview/. The issue is entitled: Teaching for Health Equity: Changing Paradigms of Medical Education. National Training Program for Comprehensive Community Physicians, Venezuela Introduction: Through the 1990s, wide disparities in health status were recorded in Venezuela, a mirror of poor social conditions, decreasing investment in the public health sector and a health workforce distribution unable to meet population health needs or to staff effective, accessible public health services. Venezuelans’ health status deteriorated as a result. In 2003-2004, the Venezuelan government launched Barrio Adentro, a new national public health model aimed at assuring primary health care coverage for the entire population of an estimated 26 million. Cuban physicians staff Barrio Adentro clinics, mainly in poor neighborhoods, until enough Venezuelan physicians can be trained to fill the posts. Intervention: Cuban experience with community-oriented medical education and global health cooperation was drawn upon to develop curriculum and provide faculty for the new National Training Program for Comprehensive Community Physicians, begun in 2005 in cooperation with six Venezuelan universities. The program differs from previous Venezuelan medical education models by adopting a stated goal of training physicians for public service, recruiting students who had no previous opportunity for university-level education, and concentrating the weight of their training on a service- and community-based model of education, relying on practicing physician-tutors. Results: Over 20,000 students have been enrolled in three years. The six

  3. [Recent and future trends in general fertility in Venezuela].

    Science.gov (United States)

    Papail, J

    1983-01-01

    Data from the 1977 Venezuela Fertility survey were used to assess recent trends in fertility and to attempt an understanding of future fertility based on observed trends. Between 1951-61, the total fertility rate increased from 5.96 to 6.61. In the 1960s, the fertility of women aged 15-30 years declined somewhat and the use of contraception and sterilization became more widespread, so that by 1971 the total fertility rate fell to 5.58. It is possible that the 1977 fertility survey slightly underrepresented women in the Caracas area, which would tend to overestimate fertility at the national level. The small sample size of 4361 women aged 15-44 involved considerable fluctuations in fertility rates from year to year. The risk of errors resulting from the method of retrospective reporting of live births appeared to be small since the recall period was relatively short. A series of quinquennial rates for women aged 15-39 was constructed for each age group from 1968-77. Fertility rates estimated for 1971 and 1976 respectively from the Venezuela Fertility Survey results using a moving average for 3 years were 120.7 and 105.1 for women 15-19, 259.0 and 225.1 for women 20-24, 255.0 and 213.1 for women 25-29, 214.3 and 167.7 for women 30-34, and 150.0 and 103.6 for women 35-39. The results were quite close to fertility rates estimated in other sources. The 1977 fertility survey indicated a trend toward later age at marriage and a correlation of ideal family size with age. The ideal number of children was 4.2 for the total sample, 5 children for women aged 35-39 years, 4.5 for those aged 30-34, 3.9 for those 25-29, and 3.5 for those aged 20-24. 55% of women in union stated they wanted no more children. 46% of women exposed to risk of pregnancy used a modern method of contraception; the proportion varied from 40% of those with 1 child to 56% with 4 children. The fertility decline, reduced ideal family size, and use of modern contraception were closely associated with

  4. Venezuela's Barrio Adentro: an alternative to neoliberalism in health care.

    2006-01-01

    Throughout the 1990s, all Latin American countries but Cuba implemented health care sector reforms based on a neoliberal paradigm that redefined health care less as a social right and more as a market commodity. These reforms were couched in the broader structural adjustment of Latin American welfare states as prescribed by international financial institutions since the mid-1980s. However, since 2003, Venezuela has been developing an alternative to this neoliberal trend through its health care reform program, Misión Barrio Adentro (Inside the Neighborhood). In this article, the authors review the main features of the Venezuelan health care reform, analyzing, within their broader sociopolitical and economic contexts, previous neoliberal health care reforms that mainly benefited transnational capital and domestic Latin American elites. They explain the emergence of the new health care program, Misión Barrio Adentro, examining its historical, social, and political underpinnings and the central role played by popular resistance to neoliberalism. This program not only provides a compelling model of health care reform for other low- to middle-income countries but also offers policy lessons to wealthy countries.

  5. Intestinal Parasitic Infections among Pregnant Women in Venezuela

    Directory of Open Access Journals (Sweden)

    2006-01-01

    Full Text Available Introduction. Intestinal parasitic infections, especially due to helminths, increase anemia in pregnant women. The results of this are low pregnancy weight gain and IUGR, followed by LBW, with its associated greater risks of infection and higher perinatal mortality rates. For these reasons, in the setting of no large previous studies in Venezuela about this problem, a national multicentric study was conducted. Methods. Pregnant women from nine states were studied, a prenatal evaluation with a coproparasitological study. Univariated and multivariated analyses were made to determine risk factors for intestinal parasitosis and related anemia. Results. During 19 months, 1038 pregnant women were included and evaluated. Intestinal parasitosis was evidenced in 73.9%: A lumbricoides 57.0%, T trichiura 36.0%, G lamblia 14.1%, E hystolitica 12.0%, N americanus 8.1%, E vermicularis 6.3%, S stercoralis 3.3%. Relative risk for anemia in those women with intestinal parasitosis was 2.56 ( P<.01 . Discussion. Intestinal parasitoses could be associated with conditions for development of anemia at pregnancy. These features reflect the need of routine coproparasitological study among pregnant women in rural and endemic zones for intestinal parasites. Further therapeutic and prophylactic protocols are needed. Additional research on pregnant intestinal parasitic infection impact on newborn health is also considered.

    Full Text Available Between February and May 2014, wide public demonstrations erupted mayor cities in Venezuela, when young people protested against violent criminality, scarcity of goods, inflation and a general perception of an uncertain future. They were violently repressed by the military police, the police and armed thugs. Fifty people died, many were injured or arrested, and about 2.500 were submitted to criminal procedure. A number of opposition leaders and mayors are still in prison. Prosecutors and judges have collaborated in the repression and have paid no attention to the massive violation of human rights. The article analyzes the meaning of such massive repression for the judicial system and the state.

El objetivo de este trabajo es determinar el nivel de calidad de la democracia en Venezuela, en el marco de una concepción procedimental de la democracia. La evaluación empírica de cinco dimensiones de calidad de la democracia (decisión electoral, participación, respuesta a la voluntad popular, rendición de cuentas y soberanía revela un nivel bajo en conjunto, con escasa variación entre 2005 y 2010. Los escenarios posibles luego de las elecciones de 2012 incluyen: reforzamiento de las tendencias autoritarias, militarización abierta, liberalización política con fortalecimiento institucional, o volatilidad duradera con conflicto polarizado y debilidad institucional.

    The comparative hourly activity of Lutzomyia ovallesi (Ortiz) and L. gomezi (Nitzulescu), vectors of cutaneous leishmaniasis in Miranda State, Venezuela, was studied between November and March during 1991-1994 using a Shannon trap with a fluorescent light. Female abundance of L. ovallesi increased from 1800 to 2000 hours, plateaued from 2000 to 2400 hours, then decreased progressively. L. gomezi always exhibited maximum activity between 1900 and 2000 hours, then declined abruptly. The importance of these activity patterns in Leishmania transmission is discussed.

  14. Tertiary evolution of the northeastern Venezuela offshore

    Ysaccis B., Raul

    1998-12-01

    On the northeastern offshore Venezuela, the pre-Tertiary basement consists of a deeply subducted accretionary complex of a Cretaceous island arc system that formed far to the west of its present location. The internal structure of this basement consists of metamorphic nappes that involve passive margin sequences, as well as oceanic (ophiolitic) elements. The Tertiary evolution of the northeastern Venezuela offshore is dominated by Paleogene (Middle Eocene-Oligocene) extension and Neogene transtension, interrupted by Oligocene to Middle Miocene inversions. The Paleogene extension is mainly an arc-normal extension associated with a retreating subduction boundary. It is limited to the La Tortuga and the La Blanquilla Basins and the southeastern Margarita and Caracolito subbasins. All of these basins are farther north of and not directly tied to the El Pilar fault system. On a reconstruction, these Paleogene extensional systems were located to the north of the present day Maracaibo Basin. By early Miocene the leading edge of the now overall transpressional system had migrated to a position to the north of the Ensenada de Barcelona. This relative to South America eastward migration is responsible for the Margarita strike-slip fault and the major inversions that began during the Oligocene and lasted into the Middle Miocene. The Bocono-El Pilar-Casanay-Warm Springs and the La Tortuga-Coche-North Coast fault systems are exclusively Neogene with major transtension occurring during the Late Miocene to Recent and act independently from the earlier Paleogene extensional system. They are responsible for the large Neogene transtensional basins of the area: the Cariaco trough, the Northern Tuy-Cariaco and the Paria sub-basins, and the Gulf of Paria Basin. This latest phase is characterized by strain-partitioning into strike slip faults, a transtensional northern domain and a transpressional southern domain that is responsible for the decollement tectonics and/or inversions of the

  18. [Increasing difficulties for scientific publication in Venezuela].

    Science.gov (United States)

    Ryder, Elena

    2014-03-01

    A very important increase in the costs of the edition of scientific journals has taken place in Venezuela, due to difficulties in obtaining imported free acid paper and other materials used for handling documents. Like other journals, Investigaci6n Clinica has been considering switching completely to a digital publication format; however there are several reasons that prevent us to doing it at this time: the journal is distributed in printed form to many national institutions, which do not have immediate access to digital information. In addition, there exists a commitment of shipment of printed issues for some international indices and in exchange with other national and foreign journals, whose printed format we receive. Another important aspect is that our University maintains a weak technological platform that makes difficult the immediacy required for the interchange with authors and consulted referees of received papers; and there is a latent danger of limitations in the use of digital technologies, due to current national politic problems. Consequently, we need to continue with the printed format, but must reduce the amount of printed issues, so as not to limit the number of papers published in each edition. Nevertheless, there is an ever increasing number of contributions from foreign researches and Investigaci6n Clinica has been recently included in two new international indices, the SEIIC from Argentina and the Infobase Index from India, reasons that obligate us to maintain our levels of excellence and commitment to our authors and readers.

  19. [Enterobiasis in students from Ciudad Bolivar, Venezuela].

    Enterobius vermicularis is a nematode with a peculiar biological cycle, thus requiring a special diagnostic technique. In order to determine the prevalence of E. vermicularis infection among schoolchildren in Ciudad Bolívar, Venezuela, 282 children aged 5-14 years old were evaluated between november 1995 and august 1996 by the Graham technique (three perianal swabs with adhesive cellulose tape). The prevalence of enterobiasis in the studied children was estimated 19.1% (54/282). There was no difference between sexes (P > 0.05), but there was a difference between ages (x2 = 13.8; 1.g. = 4), being the infection more frequent between 5 and 8 years. Symptoms were observed in 90.7% of the schoolchildren. Anal pruritus was the most common clinical finding (81.6%). Other less frequent manifestations were enuresis (28.6%) and vulvitis in girls (26.1%). This intestinal parasitosis occurs with high frequency among schoolchildren in Ciudad Bolívar with characteristic and identifiable symptoms in most cases. The Graham method must be used for its diagnosis. This test is not routinely performed in our laboratories unless specifically requested by the attending physician.

  1. In situ combustion field experiences in Venezuela

    Villalba, M.; Estrada, M.; Bolivar, J. [INTEVEP, Caracas (Venezuela)

    1995-02-01

    A literature review of four in situ combustion projects: in Miga, Tia Juana, Melones and Morichal fields in Venezuela was made, and a summary of these projects is presented. Reservoir description and project performance data were analyzed. The behavior of the four in situ combustion field tests can be summarized as follows: The problems most often encountered were corrosion and high temperature producing wells. The direction in which the burning front moved was guided essentially by reservoir characteristics. The produced oil was upgraded by about 4{degrees} API, and viscosity was substantially reduced. For Mirochal and Miga fields, the analyses of available information from the combustion projects indicated that the process has been successful in the affected region. Conclusions from this review indicate that the two most frequent problems encountered were operational problems in producing wells and the direction of the burning front. The heterogeneous nature of the sands probably resulted in the burning front moving in a preferential direction, hence reducing areal sweep efficiency.

  2. Possible association between gastric cancer and bracken fern in Venezuela: an epidemiologic study.

    2001-01-15

    To explore a possible connection between specific environmental factors that might explain the high rates of stomach cancer in people living in the highlands of western Venezuela, an epidemiologic study was conducted in 2 regions of contrasting topography. The regions embrace 3 Andean states, Mérida, Táchira and Trujillo, and the vicinal lowland surrounding the Maracaibo lake basin of Zulia State. Statistical sanitary records from 1986 to 1996 comprising 5.5 million people in the study area indicated that age-sex-adjusted gastric cancer death rate per 100,000 people (DR) was up to 3.64 times higher in highland than lowland areas, although total cancer-related DRs were comparable in both regions. DRs of other less frequent cancers from the upper alimentary tract [esophagous (1.18/0.99) and mouth-throat (1.39/2.64)] showed comparable values in both regions as well as colorectal, breast, and uterus-cervix cancers, suggesting that the stomach cancer DRs were related to geographically determined factors. Comparison of some nutrition issues, incidence of Helicobacter pylori infection in selected areas, the discovery of the bracken carcinogen ptaquiloside in milk from bracken-fed cows, the prevalence of this plant in mountain cattle households and pasturelands and the rates of bracken-evoked bovine enzootic hematuria led us to conclude that consumption of ptaquiloside-contaminated milk may contribute to human gastric cancer in the Andean states of Venezuela.

  3. Misery Index Corrected by Informality: Applicable to Venezuela

    Full Text Available This paper suggests a variation of the IMO index (Okun's Misery Index, adapting it to markets with these characteristics, adding the ESI level (Employment in the Informal Sector to the unemployment level. This research compares the evolution of several standard misery indexes in several zones during the last decades, with emphasis on the case of Venezuela, for which the new proposed index is also estimated. Results show improvement in the well-being of groups of countries under study, compared to the deterioration of the indicator in Venezuela. In general terms, the IMO is controlled by unemployment, except in Venezuela. However, preponderance of inflation over unemployment in this country seems to occur by the underestimate that the unemployment rate has on the Venezuelan labor market situation.

  4. Neogene history of the Carapita Formation, Eastern Venezuela basin

    Science.gov (United States)

    Sanchez Zambrano, Dennis Alberto

    The planktonic and benthic foraminifera from the lower to middle Miocene shales of the Carapita Formation of Eastern Venezuela in three exploration wells and one outcrop section are analyzed with the objectives of establishing a precise biostratigraphy of the formation and its bathymetric history. Comparison with the well-preserved microfaunas of the correlative Cipero Formation of Trinidad made possible the achievement of these objectives. The formation, up to 4500 to 6000 m thick in outcrops, extends from northeastern Anzoategui and North of Monagas States to the Gulf of Paria and is both an important oil reservoir towards the east and the main seal rock for the Oligocene reservoir in the north of Monagas State. In the area studied the Carapita Formation spans lower to lower middle Miocene Zones N6/M3 to N9/M6; its upper part is unconstrained as only rare long ranging early Miocene to early Pliocene planktonic foraminifera occur above the Orbulina datum. Unexpectedly, we found that the four lower to middle Miocene sections are highly discontinuous, with hiastuses as long as 4 Myr. Based on the abundance patterns of sixty-nine species of benthic foraminifera and analysis of morphotype abundance following the methodology of Corliss and Chen (1988) and Corliss and Fois (1993), we show that the Carapita Formation was deposited at outer neritic to middle bathyal depths (≥200--1000 m), whereas the Cipero Formation was deposited at middle to lower bathyal depths (≥600--2000 m). Importantly, the bathymetric changes are associated with unconformities in all sections, strongly suggesting that both (shallowing and associated unconformities) were tectonically induced.

    The complete sequences of isolates of two new bipartite begomoviruses (genus Begomovirus, family Geminiviridae) found infecting weeds in Venezuela are provided. The names proposed for these new begomoviruses are "Datura leaf distortion virus" (DLDV), isolated from a Datura stramonium L. (family Solanaceae) plant, and "Dalechampia chlorotic mosaic virus" (DCMV), isolated from infected Dalechampia sp. (family Euphorbiaceae) and Boerhavia diffusa L. (family Nyctaginaceae) plants. Phylogenetic analysis showed that these new begomoviruses segregated in two distinct clades of New World begomoviruses. To our knowledge, this is the first record of a begomovirus infecting Dalechampia sp. plants. Also, this is the first report of a begomovirus infecting Boerhavia spp. and Datura spp. in Venezuela.

Muestra también que lo que ha cambiado para ellas a lo largo del tiempo es la manera de hacer negocios en la industria petrolera venezolana, valga decir, los términos y condiciones de acceso a las actividades de exploración y producción que les ha impuesto el propietario del recurso natural, relacionados particularmente con el reparto de la renta petrolera internacional. El artículo, dividido en cuatro secciones, es una síntesis de la historia del derecho de propiedad del subsuelo, de las compañías petroleras, del Estado y de la renta petrolera internacional en Venezuela desde 1920 hasta el presente. ABSTRACT: This paper shows that in almost a century of history of the Venezuelan oil industry (1917-2009, International Oil Companies (IOCs have been doing business in this country for just more than fourth fifth of this period (74/92 years. It shows too that during that time, what has been changing in this country for the oil companies, IOCs or National Oil Companies (NOCs, is the way of doing business in the upstream of the oil industry: the terms and conditions of the owner of the underground property rights. Terms and conditions mean in this context how much of the oil generated rents in the underground public and national property rights goes to the pockets of the oil companies and government. This paper summarizes the history of the underground property rights, oil companies, the State, and rent in Venezuela from 1920 up to the present.

A través de la etnografía y entrevistas, se concluye que MBA proporcionó acceso a la atención médica y logró obtener apoyo popular a consecuencia de: movimientos sociales de los pobres; cooperación entre trabajadores comunitarios, residentes, profesionales de salud y funcionarios públicos; la integración de la atención médica con programas sociales y económicos; la ubicación de médicos como residentes en barrios pobres; interacciones positivas y equitativas médico-paciente; el papel clave de los Comités de Salud; y el impacto de la hostilidad de la prensa, un segmento grande de los médicos venezolanos y la oposición en transformar a la salud en un tema político esencial. Todo esto nos sugiere que el Estado puede confrontar las inequidades de salud cuando se unen perspectivas teóricas de la medicina social y la epidemiología crítica con los saberes populares dentro de las comunidades afectadas. Estructuras institucionales flexibles, no burocráticas y creativas aumentan la efectividad de las intervenciones.

    Full Text Available Spatial configuration of Quaternary active tectonic features along the southern Caribbean plate boundary suggests that the region is subject to a compressive strike-slip (transpressional senso lato regime, characterized by a NNW-SSE maximum horizontal stress (sH=s1 and/or an ENE-WSW minimum (s h=s3 or s2 horizontal stress. Stress inversion applied to fault-plane kinematic indicators measured essentially in Plio-Quaternary sedimentary rocks confirms this tectonic regime. Accordingly, this stress regime is responsible for the Quaternary activity and kinematics of six sets of brittle features along northern Venezuela (from Colombia in the west to Trinidad in the east: (1 east-west rightlateral faults, (2 NW right-lateral faults -acting as synthetic Riedel shears-, (3 ENE to east-west dextral faults -P shears-, (4 NNW normal faults, (5 almost north-south left-lateral faults -antithetic Riedel shears- and (6 mostly subsurface ENE reverse faults associated with folding of the same orientation. Brittle deformation conforms to the simple shear model, although not all the deformation can be accounted for it since strain partitioning is also taking place because regional folding and thrusting are due to the normal-to-structure component of the relative slip vector between the Caribbean and South America plates. On the other hand, the maximum horizontal stress in western Venezuela, particularly in the Maracaibo block and south of the Oca-Ancón fault, progressively turns counter-clockwise to become more east-west oriented, producing left- and right-lateral slip along the north-south striking and NE-SW striking faults, respectively. The orientation and spatial variation of this regional stress field in western Venezuela results from the superposition of the two major neighboring interplate maximum horizontal stress orientations (sH: roughly east-west trending stress across the Nazca-South America type-B subduction along the pacific coast of Colombia and NNW

    The growing toward decentralization and democratization of development planning in Venezuela was discussed. Venezuela has a long tradition of rule by a strong centralized authority. Currently, the Office of the President is vested with considerable power, despite the existence of an elected legislator and an independent judiciary. The president rules by decree. State legislatures are elected, but governors of the states are appointed by the president. There are also elected municipal councils. Both state and municipal governments are almost fully dependent on the federal government for both their operating and capital investment budgets. Development programs are administered through 2 systems. Specific programs are administered by almost 100 different institutes and enterprises. The activities of these various programs are coordinated by administrative bodies at the state and federal level. The 2nd administrative system operates at the regional and federal levels. The administrative body at the federal level is the Central Office for Coordination and Planning and was established by Presidential Decree in 1958. This body prepares and coordinates all national development plans. The administrative bodies at the regional level are the Regional Organizations for Development. These bodies were created in specific regions through a series of legislative acts commencing in 1969 and continuing into the present. The development of these regional bodies represented a 1st step toward decentralization. Decree 478, promulgated in 1980, further promoted the decentalization of developmental planning. The decree established a series of assemblies and councils at various levels. A National Council of Regional Development was created at the federal level, and a Regional Council of Development was established at the regional level. At the state level an Assembly of Participation was organized, and at the municipal level a Committee of Citizen Participation was established

    Weisbrot, Mark; Sandoval, Luis; Rosnick, David

    2006-01-01

    This article looks at household and individual poverty rates in Venezuela over the past seven years. For more than a year, the statement that poverty in Venezuela has increased under the government of President Hugo Chávez has appeared in scores of major newspapers, on major television and radio programs, and even in publications devoted to foreign policy. There are no data to support such statements, and in fact the available data show a decline in poverty for both individuals and households over the seven-year period: the percentage of people in poverty declined from 50 percent in the first quarter of 1999 to 43.7 percent in 2005. Further, there is no evidence to suggest any change in the methodology for measuring poverty during this period, as has been alleged in a number of reports. The article also examines briefly the impact of significant changes in non-cash benefits such as free health care, which are not taken into account in the measured poverty rate, on poor people in Venezuela. Finally, the authors look at how the mistakes in reporting on Venezuela's poverty rate were made; an appendix gives examples of mistakes in major media and foreign policy publications.

    2016-12-01

    CYP2D6 is an important cytochrome P450 enzyme that plays an important role in the metabolism of about 25% of currently prescribed drugs. The presence of polymorphisms in the CYP2D6 gene may modulate enzyme level and activity, thereby affecting individual responses to pharmacological treatments. The most prevalent diseases in the admixed population from Venezuela are cardiovascular and cancer, whereas viral, bacterial and parasitic diseases, particularly malaria, are prevalent in Amerindian populations; in the treatment of these diseases, several drugs that are metabolized by CYP2D6 are used. In this work, we reviewed the data on CYP2D6 variability and predicted metabolizer phenotypes, in healthy volunteers of two admixed and five Amerindian populations from Venezuela. The Venezuelan population is very heterogeneous as a result of the genetic admixture of three major ethnical components: Europeans, Africans and Amerindians. There are noticeable inter-regional and inter-population differences in the process of mixing of this population. Hitherto, there are few published studies in Venezuela on CYP2D6; therefore, it is necessary to increase research in this regard, in particular to develop studies with a larger sample size. There is a considerable amount of work remaining before CYP2D6 is integrated into clinical practice in Venezuela.

    2015-11-01

    We analyzed the possible effects of global climate change on the potential geographic distribution in Venezuela of five species of triatomines (Eratyrus mucronatus (Stal, 1859), Panstrongylus geniculatus (Latreille, 1811), Rhodnius prolixus (Stål, 1859), Rhodnius robustus (Larrousse, 1927), and Triatoma maculata (Erichson, 1848)), vectors of Trypanosoma cruzi, the etiological agent of Chagas disease. To obtain the future potential geographic distributions, expressed as climatic niche suitability, we modeled the presences of these species using two IPCC (Intergovernmental Panel on Climate Change) future emission scenarios of global climate change (A1B and B1), the Global Climate model CSIRO Mark 3.0, and three periods of future projections (years 2020, 2060, and 2080). After estimating with the MaxEnt software the future climatic niche suitability for each species, scenario, and period of future projections, we estimated a series of indexes of Venezuela's vulnerability at the county, state, and country level, measured as the number of people exposed due to the changes in the geographical distribution of the five triatomine species analyzed. Despite that this is not a measure of the risk of Chagas disease transmission, we conclude that possible future effects of global climate change on the Venezuelan population vulnerability show a slightly decreasing trend, even taking into account future population growth; we can expect fewer locations in Venezuela where an average Venezuelan citizen would be exposed to triatomines in the next 50-70 yr.

    2013-12-01

    Full Text Available The paper aims to study the perception of the political agents of the Congress through the analysis of their votes on the context of the acceptance of Venezuela into MERCOSUR, relating it to the potential gains coming from its admission. The relevance of the topic is justified by the importance that the bloc would acquire accepting a new member, considering the expansion of the internal consumer market and the increase of oil reserves of the bloc. Therefore, the intention is to clarify the political situation favorable to the integration and, taking the Brazilian perception in consideration, establish the relationship between economic gains that would come from the acceptance of Venezuela as a state member and the political discourse regarding this subject in the National Congress. Through the votes of deputies and senators we mapped the variables that act as important factors in the decision-making process of lawmakers. It was found that the party influence, though strong, suffers marginal effects of variables such as the influence of regional and local interests when it comes to voting on foreign policy.

    Venezuelas tectonic setting as part of the plate boundary between the Caribbean and the South American plate causes two major seismologically active fault systems: the roughly west - east trending strike slip fault system along the coast with numerous sub-parallel faults and the Bocono fault system, which dominates the Venezuelan southwest - northeast striking Andes. The main Bocono fault reaches a total length of about 500 km and has a width of approximately 100 km between the southern and northern baseline of the mountain slopes which are marked by inverse faults. This is believed to be due to strain partitioning, a concept which seems to apply as well to the Bocono fault system. The whole fault system is characterized by a high seismicity rate of small scale and intermediate event magnitudes ranging from 1.5 to 6.3 in the last fifty years. In this study we would like to present an investigation on 39 focal mechanism solutions and a b-value mapping of the Andean region with the main goal to throw light on the stess and strain situation. For recompiling the focal memchanisms calculated from first motion polarities, various sources had to been used: seismograms from stations of the local and regional networks of the Seismological Center of ULA, the national seismic network operated by FUNVISIS, the seismic network Lago Maracaibo of PDVSA and the local seismic network of DESURCA. For the b-value mapping we used the two catalogues of ULA and DESURCA of which the last one registered more than 6500 events from 1994 to 1999. The set of focal mechanism solutions studied showed normal, strike slip, and reverse faulting mechanisms concentrated in distinct areas of the Bocono fault system and thus resulting in a zonation also supported by the determinations of the azimuths of the maximum horizontal stress SHmax. This hypothesis of the zonation of the Andes region is strongly supported by the results of the b-value mapping. The zonation as seen in the varying major stress

    Streptomyces venezuelae YJ028, bearing a deletion of the entire biosynthetic gene cluster encoding the pikromycin polyketide synthases and desosamine biosynthetic enzymes, was used as a bioconversion system for combinatorial biosynthesis of glycosylated derivatives of tylosin. Two engineered deoxysugar biosynthetic pathways for the biosynthesis of TDP-3-O-demethyl-D-chalcose or TDP-Lrhamnose in conjunction with the glycosyltransferaseauxiliary protein pair DesVII/DesVIII were expressed in a S. venezuelae YJ028 mutant strain. Supplementation of each mutant strain capable of producing TDP-3-O-demethyl- D-chalcose or TDP-L-rhamnose with tylosin aglycone tylactone resulted in the production of the 3-O-demethyl- D-chalcose, D-quinovose, or L-rhamnose-glycosylated tylactone.

    Site effects have been recognized to play an important role in damage distribution of destructive earthquakes. These effects have been observed in Venezuela especially during the 1967 Caracas earthquake, when 4 buildings with 10 and more storeys during the Caracas 1967 earthquake collapsed, and a big number of them in the same deep sediment area have been seriously damaged. This motivated the development of studies regarding the subsurface configuration of Caracas and Barquisimeto during the last decade, with a seismic microzoning project realized in both cities from 2005 to 2009. The main results of this project were the development of design response spectra for the different microzones within the sedimentary basin, as well as estimates of landslide hazard. Implementation of the results in municipality ordinances is actually discussed with local authorities. They are aimed to address mitigation for new constructions by the application of the specific design spectra, for existing buildings via evaluation and retrofitting strategies, and for slope areas (informal, as well as formal developments) due to the identification of areas that may not be developed or require detailed studies of slope stabilities. Since then, seismic microzoning studies were started in Cumaná, Guarenas/Guatire and Lara state, and within a broader context of integrated risk management, which includes flooding, landslide and technological risks, in Mérida, Valencia, Maracay, Barcelona/Puerto La Cruz and Valle de la Pascua. The projects are coordinated by the Venezuelan Foundation for Seismological Research (FUNVISIS) in cooperation with local universities. Efforts are done to unable local researchers to apply the methodologies in other cities as Valera, Trujillo, Boconó, San Cristóbal and Tucacas. A unified seismic hazard map as input motion to these studies is actually in development. Depending on the local characteristics, building inventory and vulnerability analysis are done for risk

    Full Text Available El delito de secuestro es un flagelo social que ha experimentado mutaciones en el tiempo. El año 2009 terminó con una cifra sin precedentes en cuanto a los secuestros reportados en Venezuela. Los datos aportados por los organismos oficiales revelan que durante el 2008 hubo 537 secuestros, lo cual representa un aumento de 52% respecto al total del 2007, mientras que en el 2009 la cifra se incrementó en un 62,82%, en relación con el año anterior. Esta investigación tiene como objetivo describir el delito de secuestro en Venezuela, con especial referencia al Estado Zulia, población fronteriza limítrofe con Colombia. Para ello se emplea una metodología de tipo documental- descriptiva. Se revela que no existen esquemas predefinidos que permitan caracterizar este tipo penal, pues, tal y como ha venido sucediendo, es susceptible de llevarse a cabo en cualquier momento y circunstancia, no de modo exclusivo en sujetos de alto estatus socioeconómico, sino con mínimos medios para responder a las exigencias de los plagiarios; de aquí la proliferación de la modalidad del llamado secuestro exprés. El delito de secuestro en Venezuela ha cambiado en forma notable sus patrones: de ser un delito predominantemente político, fronterizo y ejecutado por grupos organizados, ha pasado a ser uno de objetivos sobre todo económicos, urbano, y ejecutado con un fin de lucro por la delincuencia común. En verdad, el Estado Zulia sigue repuntando en la lista de los estados con mayor incidencia de este delito en Venezuela, pero no es el principal, pues ha sido desplazado en posicionamiento por otras urbes del país, encabezadas en la actualidad por la ciudad capital de Caracas.

    2006-06-01

    Full Text Available This article analyzes the changes in violence in Venezuela during the last forty years. It links the ups and downs of the oil revenues and the political crisis of the country to the changes in the homicide rates, which increased from 7 per 100 thousand inhabitants in 1970 to 12 in 1990, 19 in 1998 and 50 in 2003. The article characterizes Venezuela as a rentist society and shows its trajectory from rural violence to the beginning of urban violence, the guerilla movements of the 60s, the delinquent violence related to the abundance of oil revenues and the violence during the popular revolt and the sackings of 1989 in Caracas. After this, we analyze the coups d'état of 1992 and the influence the political violence exerted upon criminal violence. We describe the political and party changes in the country, their influence upon the stabilization of homicide rates since the mid-90s and their remarkable increase during the H. Chávez government. The article finishes with an analysis of the current situation, the official prohibition to publish statistics on homicides and with some thoughts about the perspective of greater violence in Venezuela.

    Eid, Mahmoud; Nahon-Serfaty, Isaac

    2015-01-01

    The prevalence of breast cancer in Venezuela is particularly alarming, which is attributed to healthcare inequalities, low health literacy, and lagging compliance with prevention methods (i.e., screening and mammography). While the right to health is acknowledged by the Venezuelan constitution, activism beyond governmental confines is required to increase women's breast cancer awareness and decrease mortality rates. Through the development of social support and strategic communicative methods enacted by healthcare providers, it may be possible to empower women with the tools necessary for breast cancer prevention. This paper discusses issues surrounding women's breast cancer, such as awareness of the disease and its risks, self-advocacy, and the roles of activists, healthcare providers, and society. Specifically, it describes a four-year action-oriented research project developed in Venezuela, which was a collaborative work among researchers, practitioners, NGOs, patients, journalists, and policymakers. The outcomes include higher levels of awareness and interest among community members and organizations to learn and seek more information about women's breast cancer, better understandings of the communicated messages, more media coverage and medical consultations, increasing positive patient treatments, expansion of networking of NGOs, as well as a widely supported declaration for a national response against breast cancer in Venezuela.

    2013-01-01

    In 1999, newly-elected Venezuelan President Hugo Chávez initiated a far-reaching social movement as part of a political project known as the Bolivarian Revolution. Inspired by the democratic ideologies of Simón Bolívar, this movement was committed to reducing intractable inequalities that defined Venezuela's Fourth Republic (1958-1998). Given the ambitious scope of these reforms, Venezuela serves as an instructive example to understand the political context of social inequalities and population health. In this article, we provide a brief overview of the impact of egalitarian policies in Venezuela, stressing: (a) the socialist reforms and social class changes initiated by the Bolivarian Movement; (b) the impact of these reforms and changes on poverty and social determinants of health; (c) the sustainability of economic growth to continue pro-poor policies; and (d) the implications of egalitarian policies for other Latin American countries. The significance and implications of Chávez's achievements are now further underscored given his recent passing, leading one to ask whether political support for Bolivarianism will continue without its revolutionary leader.

  2. Comparison of fish assemblages in two littoral habitats in a Neotropical morichal stream in Venezuela

    Carmen G. Montaña

    Full Text Available Morichales are lowland streams in South American savannas with riparian forest dominated by the moriche palm (Mauritia flexuosa. We sampled littoral habitats from ten flooded vegetated patches (dominated by Mauritiella aculeate and six sand banks in two months of the dry season (Feb-Mar 2005 in a stream in the savannas of Apure State, Venezuela. We collected samples that compromised 12,407 individual fishes of 107 species. Small-bodied fishes (< 100 mm, representing diverse trophic and life history strategies, were abundant. The most abundant species were in the families Characidae and Cichlidae. Fish assemblages from flooded vegetated patches differed significantly from those on adjacent sand banks. High structural complexity along vegetated shoreline habitats of morichal streams likely contributes to species richness and affects assemblage composition.

  3. Analysis of antenal sensilla patterns of Rhodnius prolixus from Colombia and Venezuela

    Directory of Open Access Journals (Sweden)

    Lyda Esteban

    2005-12-01

    Full Text Available Antennal sensilla patterns were used to analyze population variation of domestic Rhodnius prolixus from six departments and states representing three biogeographical regions of Colombia and Venezuela. Discriminant analysis of the patterns of mechanoreceptors and of three types of chemoreceptors on the pedicel and flagellar segments showed clear differentiation between R. prolixus populations east and west of the Andean Cordillera. The distribution of thick and thin-walled trichoids on the second flagellar segment also showed correlation with latitude, but this was not seen in the patterns of other sensilla. The results of the sensilla patterns appear to be reflecting biogeographic features or population isolation rather than characters associated with different habitats and lend support to the idea that domestic R. prolixus originated in the eastern region of the Andes.

    2005-10-01

    The privileged location of Venezuela along an active interplate deformation belt, despite of being a "so-called" developing country, has led to a long paleoseismic tradition as attested by 45 trench assessments since 1968. Since then, a first 2-trench study was carried out by the American Woodward-Clyde company across the Oca fault at Sinamaica. Since 1980, all further paleoseismic studies have been performed by FUNVISIS and the Uribante-Caparo hydroelectric project (southern Mérida Andes) became their first assessment where 22 huge trenches were bulldozer-dug. Except for these Compañía Anónima de Administración y Fomento Eléctrico (CADAFE) financed trenches and two others, all other assessments were for Petróleos de Venezuela S. A. -PDVSA-. In this paper, geographic and geologic factors, as well as logistic limitations, conditioning success in paleoseismic studies by trenching, shall be discussed based on the Venezuelan experience developed over the years. The scientific contribution of this approach refer to: confirmation of Holocene fault activity, slip-per-event and average slip rate of a given fault (or segment), seismic potential (repeat of maximum credible earthquakes) of known faults, fault segmentation, fault interaction as consequence of stress loading by stick-slip on contiguous faults, time-space distribution of seismic activity along a given tectonic feature, seismotectonic association of historical earthquakes and landscape evolution on the short term and its implications on the long-term evolution (poorly discussed since this is really part of the field of Neotectonics). In recent years (since 1999), a new approach has been introduced in Venezuela consisting in complementing the seismic history derived from trenching studies with the evaluation of seismically induced perturbations in the continuous Quaternary sedimentary record of (either active or fossil) lakes. The future of this discipline in Venezuela heads to more trenching and lake

    Full Text Available On May 7th of 2012, Organic Law on Work, male workers and female workers —Ley Orgánica del Trabajo, los Trabajadores y Trabajadores (LOTTT— was published in Official Gazette of the Degree with Rank, Value and Force in Venezuela. The aim of this law is “to protect the work as a social fact and guarantee the labor rights, creators of the produced social wealth and the leading subjects of the processes of education and work to achieve the aims of the democratic state and social rights and justice…”. To achieve these aims changes were established that apparently benefit the employees and place them in a better situation, in respect to the 1997 law, and on the benefits of the entrepreneur. In this sense, the aim of the present article is to analyze the economic impacts that this law has had on both the employee and the entrepreneur, using a review of the literature and journals. It was observed that the most significant changes were in the reduction of the workday, the calculation and the retroactivity of the social benefits, the elimination of outsourcing, and other less significant changes such as, pre and postnatal period extension, the calculation of the overtime, the elimination of the outstanding performance bonus, among others. It was shown, without any doubt, that this law is highly punitive for the entrepreneurs and very protective for the employees. All these came along with a decrease in the Economically Active Population (PEA, with a decrease in the gross domestic product and, thus, productivity. And now with the highest levels of inflation in Latin America, this is an unflattering landscape for companies in Venezuela.

    2015-10-01

    In order to assess the qualitative pattern of food consumption in urban families of Anzoátegui, Venezuela, 300 domestic groups that combined a total of 1 163 people were studied. The domestic dietary pattern was addressed by the method of qualitative frequency of food consumption, which applied a structured survey that yielded the usual frequency of intake of a food or food group over a given period. The information was obtained through an interview with the person responsible for the procurement of food in every home, and included basic data for the socioeconomic and nutritional profile of the families studied. The qualitative analysis of the diet was obtained by comparing the different food groups that constitute the actual consumption pattern of the population studied, with official feeding guidelines suggested for the Venezuelan population. The present study showed that the qualitative pattern of food consumption in the urban population evaluated is characterized by slightly adjusted to the promotion of health and control of diet-related diseases. The family food proved to be far from the guidelines established by the dietary guidelines for Venezuela and consumption patterns are fairly homogeneous in the different socioeconomic strata. The foods most consumed daily were salt, coffee, dressing and precooked corn flour as well as beef, chicken and the higher weekly food consumption pastas. 90% of the food consumed daily is technologically processed. The results contribute to increase knowledge about the food situation of the Venezuelan population, and technically could direct the efforts of the authorities to reconcile the development of the productive sector and food supply, whereas a pattern qualitatively inadequate intake directly affects the individual biological functioning, and results in the collective conditioning of unfavorable health states.

    Adverse drug reactions (ADRs) represent the first cause of change of the first-line highly active antiretroviral therapy (HAART) regimen, therefore, they constitute the main limiting factor in the long-term follow up of HIV patients in treatment. A retrospective study was carried out in a specialized center in Lara State, Venezuela, including 99 patients over 18 years of age who had change of first-line HAART regimen due to ADRs, between 2010 and 2013. The aims of this research were to describe the sociodemographic and clinical variables, frequency of ADRs related to change of HAART, duration of the first-line HAART regimen, to determine the drugs associated with ARVs and to identify the risk factors. The ADRs constituted 47.5% of all causes of change of first-line HAART regimen, the median duration was 1.08±0.28 years. The most frequent ADRs were anemia (34.3%), hypersensitivity reactions (20.2%) and gastrointestinal intolerance (13.1%). The most frequent ARV regimen type was the protease inhibitors-based regimen (59.6%), but zidovudine was the ARV most linked to ADRs (41.4%). The regression analysis showed increased risk of ADRs in singles and students in the univariate analysis and heterosexuals and homosexuals in multivariate analysis; and decreased risk in active workers. The present work shows the high prevalence of ADRs in the studied population and represents the first case-based study that describes the pharmacoepidemiology of a cohort of HIV-positive patients treated in Venezuela.

    prehispanic extinct groups are difficult. Admixture of Neoamerican groups has been characterized by unions between European males and Amerindian females. This allows the identification in present populations of Amerindian mitocondrial haplogroups which give information on ancestral groups. In order to investigate female lineages present in western Venezuela, RFLP haplogroups from mtDNA were obtained from 193 individuals with grandparents from this region, 81 from the State of Lara (Barquisimeto and 112 from 3 towns of the State of Falcon (Macuquita=25; Macanilla=29 and Churuguara=58. Comparison of haplogroup distributions between groups was performed, and admixture estimates based on female lineages were obtained. The distribution of four Amerindian haplogroups was compared with those of other populations from the American Continent. In our four samples Amerindian haplogroups predominate, followed by those of African origin. In the comparison of the mtDNA Amerindian fraction with other populations we find that Macanillas, Lara and Churuguara are similar to South American and Amazonian groups whilst Macuquita is similar to groups from Aruba. Our findings suggest an important genetic diversity in this region, explained by migration routes to and from the south and the Caribean. They also suggest genetic relationship between prehispanic groups from Aruba and those from the Paraguaná peninsula, which have been inferred by archeological evidences. An increase in sample size and analysis of sequences for more precision is recommended.

    Full Text Available The year 2006 marked a milestone in the history of the regional integration of Venezuela. After 33 years as a member of CAN, the country withdrew from the integration agreement and joined Mercosur, marking a significant change in regional integration strategy. In this paper, the causes of this change, as well as its economic and political effects, have been analyzed through desk research. One of the main conclusions is that Chavez decided to use regional integration as a tool to address the liberal policies of the United States, regardless of the economic consequences. Another is that, due to the economic and institutional deterioration of Venezuela, the non-oil productive sector is not ready to compete with other members of Mercosur.

    In Venezuela, mammals represent an important group of wildlife with high anthropogenic pressures that threaten their permanence. Focused on the need to generate baseline information that allows us to contribute to document and conserve the richness of local wildlife, we conducted a mammalogical inventory in Yurubí National Park, located in Yaracuy State in Venezuela. We carried out fieldworks in three selected vegetation types: an evergreen forest at 197m, a semi-deciduous forest ranging between 100-230m, and a cloud forest at 1 446m. We used Victor, Sherman, Havahart and pitfall traps for the capture of small non-volant mammals and mist nets for bats. In addition, we carried out interviews with local residents and direct-indirect observations for medium-large sized mammals. At least 79 species inhabit the area, representing 28% of the species recorded for the North side of the country. Chiroptera (39 spp.), Carnivora (13 spp.) and Rodentia (9 spp.) were the orders with the highest richness, as expected for the Neotropics. The evergreen forest had the greatest species richness (n=68), with a sampling effort of 128 net-hours, 32 bucket-days, 16 hours of observations, and three persons interviewed, followed by cloud forest (n=45) with 324 net-hours, 790 traps-night, 77 bucket-days, 10 hours of observations, and one person interviewed. The lowest richness value was in the semi-deciduous forest (n=41), with 591 traps-night, 15 net-hours, 10 hours of observations and three persons interviewed. Data and observations obtained in this inventory (e.g., endemism, species known as "surrogate species" threatened in Venezuela) give an important role at the Yurubí National Park in the maintenance and conservation of local ecosystems and wildlife, threatened by human pressures in the Cordillera de la Costa.

En algunos países latinoamericanos como Colombia, Chile, Argentina, Brasil, Costa Rica se han impulado procesos de descentralización con el fin de racionalizar la actividad estatal y, precisamente, contribuir a la gobernabilidad.En Venezuela la Comisión para la Reforma del Estado (COPRE implementó la descentralización en 1988 como una forma de superar el modelo estado céntrico, caracterísitico de las últimas décadas en el país. El proceso no estuvo acompañado por cambios constitucionales, lo que condujo a conflictos entre diversas normas y al consiguiente retraso en la implementación de las nuevas políticas. El ejercicio descentralizador se está desarrollando principalmente a nivel político, por ejemplo, en los municipios de Chacao, Baruta, El Hatillo y Libertador, que pertenecen al Area Metropolitana Interna de Caracas. Así, el proceso descentralizador se vive con diferencias marcadas resultantes del tipo de administración implementada desde la alcaldía, la mayor o menor disponibilidad de resursos económicos y humanos, la población y la pobreza.ABSTRACT: Decentralization is one of the mechanisms by which the central State transfers political and administrative competences to the localities, sometimes with the purpose of strenghtening political participation, to achieve state efficiency of to look for gobernability.

    Full Text Available Quantitative parameters of intestinal helminth species and their potential relations to host characteristics in a population of capybaras (Hydrochoerus hydrochaeris from Venezuela are reported for the first time. The intestines of 40 capybaras were collected during the 1992-annual harvest at Hato El Cedral. Six helminth species were found: 2 cestodes (Monoecocestus macrobursatum, M. hagmanni, 2 nematodes (Viannella hydrochoeri, Protozoophaga obesa, and 2 trematodes (Hippocrepis hippocrepis, Taxorchis schistocotyle. This is the first report for M. macrobursatum in Venezuela. Helminth abundance did not differ between sexes or age classes. Although patterns of distribution for all helminth species were overdispersed, the high prevalence found for all species (over 70% and the high abundance observed for nematodes made it difficult to assess the effect that these helminths may produce on capybaras. Nevertheless, the negative associations found between the body condition of capybaras and helminth intensity for M. macrobursatum and V. hydrochoeri, might be pointing out potential host population regulatory role for these parasites which require further research.

    Free-living amoebae of Acanthamoeba genus are opportunistic pathogens distributed worldwide. Strains included in this genus are causative agents of a fatal encephalitis and a sight-threating keratitis in humans and other animals. In this study, 550 clinical samples which were collected between 1984 and 2014 from different patients with suspected infections due to Acanthamoeba were initially screened for the presence of this amoebic genus at the Laboratorio de Amibiasis-Escuela de Bioanálisis at the Universidad Central de Venezuela. Samples were cultured in 2% Non-Nutrient agar plates seeded with a layer of heat killed Escherichia coli. From the 550 clinical samples included in this study, 18 of them were positive for Acanthamoeba genus after culture identification. Moreover, positive samples were confirmed after amplification of the Diagnostic Fragment 3 (DF3) of the Acanthamoeba18S rDNA genus and sequencing was carried out in order to genotype the isolated strains of Acanthamoeba. Furthermore, the pathogenic potential of the strains was checked by performing thermotolerance and osmotolerance assays. Sequencing of the DF3 region resulted in the identification of genotype T4 in all the isolated strains. Moreover, most isolates were thermotolerant or both thermotolerant and osmotolerant and thus were classified as potentially pathogenic strains. To the best of our knowledge, this is the first report on the molecular characterization at the genotype level of Acanthamoeba strains in Venezuela.

    The enzymatic modification of aminoglycosides by aminoglycoside-acetyltransferases (AAC), aminoglycoside-adenyltransferases (AAD), and aminoglycoside-phosphotransferases (APH), is the most common resistance mechanism in P. aeruginosa and these enzymes can be coded on mobile genetic elements that contribute to their dispersion. One hundred and thirty seven P. aeruginosa isolates from the University Hospital, Cumana, Venezuela (HUAPA) were evaluated. Antimicrobial susceptibility was determined by the disk diffusion method and theaac, aadB and aph genes were detected by PCR. Most of the P. aeruginosa isolates (33/137) were identified from the Intensive Care Unit (ICU), mainly from discharges (96/137). The frequency of resistant P. aeruginosaisolates was found to be higher for the aminoglycosides tobramycin and amikacin (30.7 and 29.9%, respectively). Phenotype VI, resistant to these antibiotics, was the most frequent (14/49), followed by phenotype I, resistant to all the aminoglycosides tested (12/49). The aac(6´)-Ib,aphA1 and aadB genes were the most frequently detected, and the simultaneous presence of several resistance genes in the same isolate was demonstrated. Aminoglycoside resistance in isolates ofP. aeruginosa at the HUAPA is partly due to the presence of the aac(6´)-Ib, aphA1 andaadB genes, but the high rates of antimicrobial resistance suggest the existence of several mechanisms acting together. This is the first report of aminoglycoside resistance genes in Venezuela and one of the few in Latin America. PMID:27007556

    Breast cancer incidence and mortality rates are of concern among Latin American women, mainly due to the growing prevalence of this disease and the lack of compliance to proper breast cancer screening and treatment. Focusing on Venezuelan women and the challenges and barriers that interact with their health communication, this paper looks into issues surrounding women's breast cancer, such as the challenges and barriers to breast cancer care, the relevant ethics and responsibilities, the right to health, breast cancer risk perception and risk communication, and the media interventions that affect Venezuelan women's perceptions and actions pertaining to this disease. In particular, it describes an action-oriented research project in Venezuela that was conducted over a four-year period of collaborative work among researchers, practitioners, NGOs, patients, journalists, and policymakers. The outcomes include positive indications on more effective interactions between physicians and patients, increasing satisfactions about issues of ethical treatment in providing healthcare services, more sufficient and responsible media coverage of breast cancer healthcare services and information, a widely supported declaration for a national response against breast cancer in Venezuela, and the creation of a code of ethics for the Venezuelan NGO that led the expansion of networking in support of women's breast cancer healthcare.

    The enzymatic modification of aminoglycosides by aminoglycoside-acetyltransferases (AAC), aminoglycoside-adenyltransferases (AAD), and aminoglycoside-phosphotransferases (APH), is the most common resistance mechanism in P. aeruginosa and these enzymes can be coded on mobile genetic elements that contribute to their dispersion. One hundred and thirty seven P. aeruginosa isolates from the University Hospital, Cumana, Venezuela (HUAPA) were evaluated. Antimicrobial susceptibility was determined by the disk diffusion method and theaac, aadB and aph genes were detected by PCR. Most of the P. aeruginosa isolates (33/137) were identified from the Intensive Care Unit (ICU), mainly from discharges (96/137). The frequency of resistant P. aeruginosaisolates was found to be higher for the aminoglycosides tobramycin and amikacin (30.7 and 29.9%, respectively). Phenotype VI, resistant to these antibiotics, was the most frequent (14/49), followed by phenotype I, resistant to all the aminoglycosides tested (12/49). The aac(6´)-Ib,aphA1 and aadB genes were the most frequently detected, and the simultaneous presence of several resistance genes in the same isolate was demonstrated. Aminoglycoside resistance in isolates ofP. aeruginosa at the HUAPA is partly due to the presence of the aac(6´)-Ib, aphA1 andaadB genes, but the high rates of antimicrobial resistance suggest the existence of several mechanisms acting together. This is the first report of aminoglycoside resistance genes in Venezuela and one of the few in Latin America.

    Steam injection is a major oil recovery method in Venezuela, with 3 trillion bbl of oil possibly recoverable by this technqiue. Alongside progress in steam injection technology, the development of a series of numerical simulators has been proceeding at an accelerated pace. This work describes 3 of the steam injection simulators developed, and their application to 2 major heavy oil reservoirs. These simulators describe 3-phase, nonisothermal multicomponent flow, consisting of 4, 3, and 2 components, respectively, in 3 dimensions. The implicitness of the simulators increases in the order of decreasing number of components. However, for a variety of problems, the less implicit but more efficient simulators are adequate. The finite difference methods used for each simulator are outlined. These, as well as the computational performance, are compared with the existing simulators. The application of the simulators to 2 major reservoirs in Venezuela-morichal and M/sup -6/ is described and compared. Effects of such factors as spacing, injection rate, and gravity segregation are examined. 14 references.

    Full Text Available This paper addresses a core puzzle: why is continued citizen mobilization accompanied by growing disempowerment of those same citizens? Why do movements fail, leaders burn out and members disperse, and what are the implications of this organizational failure for demo¬cratic representation? Our consideration of the issues is rooted in a close examination of urban movements, mobilization, empowerment and disempowerment in the recent experience of Venezuela and Perú. The puzzle that concerns us is of course not limited to these two countries: it is common to all the Andean republics, and in different ways, to much recent experience of urban mobilization in Latin America and beyond. After a brief account of urban citizen move¬ments and politics in our two cases, we outline general reflections on the nature of empowerment and disempowerment, on the peculiar combination of strengths and weaknesses that mark many contemporary movements. A close examination of types of movements and their links with poli¬tical parties and protest follows. The character of city life is important here. We close with analysis of recent waves of urban mobilization in Perú (that sparked the ouster of president Alberto Fujimori and in Venezuela (both for and against president Hugo Chávez Frías, and with reflections on the likely future of empowerment and disempowerment for urban citizens and the implications of this perspective for democratic representation

    The circulation of wild measles virus was interrupted in Venezuela in February 2007 after the catch-up vaccination (1994) and monitoring (1998) and in response to the measles outbreak in 2001. Traditionally, the routine coverage with measles-mumps-rubella vaccine does not exceed 85%. In February 2006, a measles outbreak started by importation in the State Miranda; this extended to 7 states and lasted 50 weeks with an intermediate period of 17 weeks without reported cases. New cases were reported in the States Guarico and Amazon. The pattern of circulation of the silent period was determined through the use of retrospective search for measles; this showed that 57% of suspected cases did not enter the surveillance system. Molecular epidemiology made it possible to identify B3 as only genotype, which also circulated in Spain. The epidemiological and clinical characteristics of measles have been modified; these determine outbreaks identified late, of slow expansion, silent, and with limited case-fatality, compared with classical outbreaks. The outbreak spread by that behavior was not recognized and the classical control measures did not result. The beginning of a broader and intense vaccination was delayed, partly by weaknesses in the sensitivity of the system. It is crucial to recognize the new behavior of measles and the effectiveness of the classical control measures, and especially to establish criteria for interruption of the circulation to control an outbreak in this stage of elimination.

    Between 1975 and 1987, epidemiological studies were carried out in several rural and urban communities in the central part of western Venezuela, especially in the state of Lara. 115 positive cultures were obtained from human cases and identified by their reactivity patterns to a cross-panel of specific monoclonal antibodies using a radioimmune binding assay; 53 were Leishmania venezuelensis and 62 were L. braziliensis. Most of these stocks were also characterized by isoenzyme electrophoresis, which confirmed the identification of the L. venezuelensis isolates. The enzyme electrophoretic profiles of the L. braziliensis isolates, however, revealed two populations with distinct electromorphs, one related to the World Health Organization L. braziliensis reference strain while the other population appeared to be a hybrid between L. braziliensis and L. guyanensis. L. braziliensis variants showed the widest geographical distribution, and were found in 7 states: Districto Federal (Caracas); Lara (Barquisimeto, Crespo, Iribarren, Jimenez, Morán, Palavecino, Torres, Urdaneta); Nueva Esparta (Margarita); Portuguesa (Las Cruces, Rio Amarillo); Trujillo (Cuicas); Yaracuy (Agua Fria, Cambural, Guaremal); and Zulia (Zipa-Yare). L. venezuelensis was found in the following endemic regions: Lara (Barquisimeto, Iribarren, Jimenez, Morán); Merida (Zéa); and Yaracuy (Campos Elias), showing that this parasite has a much wider geographical distribution than was initially recognized and that both these species can occur simultaneously within the same endemic region. Five isolates of L. braziliensis were made from infected donkeys (Equus asinus) in Urdaneta, Lara State, suggesting a possible domestic reservoir of L. braziliensis.

    The Rhizophora mangle roots form a complex ecosystem where a wide range of organisms are permanently established, reproduce, and find refuge. In this study, we assessed the diversity of bivalves and gastropods that inhabit red mangrove roots, in isla Larga, Mochima, Venezuela Sucre state. Bimonthly collections were made from January 2007 to May 2008, in four study areas denominated: South, North, East and West. In each area, five mangrove roots were sampled, and the specimens were obtained. We analyzed a total of 180 roots and a total of 35 bivalve species and 25 gastropod species were found. The most abundant bivalves were: Isognomon alatus, Isognomon bicolor, Ostrea equestris, Crassostrea rhizophorae and Brachidontes exustus; among gastropods, the most common where: Littorina angulifera, (Cymatium pileare and Diodora cayenensis. The months with the highest abundances and number of individuals for both groups were January and July 2007, and March 2008. The mangrove ecosystem in isla Larga, presented a number of individuals and species higher than those reported for other regions in Venezuela and the Caribbean.

    Full Text Available This paper addresses the process of decentralization in Venezuela, under mayors’ perspective, elected for the period 2000-2004. Our main goal is to identify the vision they have over such an important process that theoretically strengthens, supports, and enhances the democratic system. We contrast decentralization theory (which states that if there is not democracy at levels of government closer to the citizens-municipal government-democracy is not sustained over real bases with what Venezuelan mayors exposed about the facts observed in the nation in this sense. Our hypothesis is that the concepts and visions that the mayors expressed must coincide with the theory sustaining decentralization in general and particularly decentralization in Venezuela, which must coincide with their praxis in their municipalities. We concluded that the positive perspectives and visions as the negatives or pessimistic ones stated by the interviewed mayors coincided with theory supporting decentralization in different countries and with the evaluations of decentralization that have been conducted in different nations. Venezuelan decentralization process is not different from those that have been discovered in other countries in this sense. It seems to be that the decentralization policy in Venezuela enjoys the same virtues and suffers the same problems that decentralization policies in other countries.

Además se hacen consideraciones sobre los sistemas de producción, destacando limitaciones, avances y sugerencias. La fruticultura en Venezuela ocupa el 3er. lugar dentro del sector agrícola vegetal. Existen 167.691 Ha de frutales y una producción 2.232.088 TM por año. Se producen comercialmente una docena de rubros frutícolas, siendo los principales: plátano, banano, naranjo y piña. Las áreas de producción van desde zonas bajas y áridas, en donde se obtienen uvas y piñas; hasta zonas altas y húmedas donde se hallan duraznos y fresas. Ha habido reducción de la superficie plantada, con excepción de lechosa, piña y aguacate. El manejo hortícola de los huertos frutícolas es heterogéneo, ya que se observa desde bajo hasta alto nivel de tecnología. La incorrecta aplicación de las prácticas hortícolas origina baja productividad y calidad de fruta. La poscosecha podría mejorarse a través del desarrollo e implementación de normas de clasificación, empaque, embalaje, y cadena de frío. La exportación de frutas venezolanas se ha reducido en los últimos años y se concentra en mango, naranja y lima Tahití. Los principales destinos son Colombia, Europa, Norteamérica y las islas del Caribe. Sólo la naranja se procesa de manera importante en Venezuela. Las perspectivas para la fruticultura venezolana es continuar como una actividad dirigida al mercado interno, no se vislumbra una mayor participación del país en el mercado internacional.

  12. The Crustal Structure and Seismicity of Eastern Venezuela

    Eastern Venezuela is characterized by a moderate to high seismicity, evidenced recently by the 1997 Cariaco earthquake located on the El Pilar Fault, a right lateral strike slip fault which marks the plate boundary between the Caribbean and South-American plates in this region. Recently, the seismic activity seems to migrate towards the zone of subduction of the Lesser Antilles in the northeast, where a mb 6.0 earthquake occurred in October 2000 at 120 km of depth. Periodical changes in the seismic activity are related to the interaction of the stress fields of the strike-slip and the subduction regimes. The seismic activity decreases rapidly towards to the south with some disperse events on the northern edge of the Guayana Shield, related to the Guri fault system. The crustal models used in the region are derived from the information generated by the national seismological network since 1982 and by microseismicity studies in northeastern Venezuela, coinciding in a crustal thickness of about 35 km in depth. Results of seismic refraction measurements for the region were obtained during field campains in 1998 (ECOGUAY) for the Guayana Shield and the Cariaco sedimentary basin and in 2001 (ECCO) for the Oriental Basin. The total crustal thickness decreases from about 45 km on the northern edge of the Guayana Shield to some 36 km close to El Tigre in the center of the Oriental Basin. The average crustal velocity decreases in the same sense from 6.5 to 5.8 km/s. In the Cariaco sedimentary basin a young sedimentary cover of 1 km thickness with a seismic velocity of 2 km/s was derived. Towards the northern limit of the South-American plate, no deep seismic refraction data are available up to now. The improvement of the crustal models used in that region would constitute a step forward in the analysis of the seismic hazard.

    Enteric Helicobacter species (Helicobacter pullorum, Helicobacter pametensis, Helicobacter canadensis, Helicobacter anseris, and Helicobacter brantae) have been found in birds from temperate latitudes. We evaluated the occurrence of Helicobacter spp. in terrestrial wild birds from Venezuela. A fragment of 16S rRNA gene was amplified by PCR with Helicobacter genus-specific primers. Helicobacter spp. were detected in four of 80 fecal and in three of 42 intestinal tissue samples. Analyses of 16S and 23S rRNA gene sequences confirm for the first time the presence of Helicobacter in tropical terrestrial wild birds. However, the occurrence of Helicobacter was low, suggesting these bacteria may be uncommon in the populations we studied.

  4. Embodying racism: race, rhinoplasty, and self-esteem in Venezuela.

    2013-03-01

    In this article, I examine how race motivates women's decisions to undergo aesthetic rhinoplasty in Caracas, Venezuela. Through a combination of cultural domain analysis and thematic analysis of qualitative interviews, I explore how the preference for whiteness and associated facial features dovetail with the aesthetic ideals promoted by cosmetic surgeons. Rhinoplasty is offered by physicians and interpreted by patients as a resolution to body dissatisfaction and low self-esteem. The clinical ethos of objectivity established by cosmetic surgeons fails to acknowledge how perceptions of the self and body are strongly tied to racial marginalization: patients' efforts to alter the nose reveal attempts to change not only how the body looks, but how it is lived. As a result, cosmetic surgery only acts as a stop-gap measure to heighten one's self-esteem and body image.

The chorionic sculpturing of L. migonei, L. ovallesi, L. absonodonta and L. gomezi was characterized by series of columns arranged in palisade to form sinuous ridges. In inter-ridge areas, the basal layer was covered with fibrous material. The outer chorion of L. panamensis had a pattern known as "mountain- or volcano-like". The morphology of the posterior pole and aeropyle had a common structure in the five species, with some species-specific characters. The eggshell features of the five species are compared with those of other phlebotomine sand flies.

    Sixty-five percent of the ≈19 mm/yr eastward velocity of the Caribbean Plate north of Aruba and the Guajira peninsula relative to the South American plate is accommodated by dextral slip on the Bocono Fault system in NW Venezuela at 12±1 mm/yr, the remaining ~3 mm/yr of shear apparently distributed to the NW of the fault (Perez et al., 2011). The N40E strike of the Bocono fault system, however, requires that 10.6±1 mm/yr of convergence should accompany this partitioned dextral shear, but GPS measurements reveal that less than 25% of this convergence occurs across the Venezuelan Andes. The remaining 6-8 mm of convergence is presumably accommodated by incipient subduction between the Bocono fault and a trench 300 km NW of the northern coast of Colombia. Hence NW Venezuela and NE Colombia may occasionally host great earthquakes. Our current poor understanding of the geometry of the plate interface permits the plate to be locked 300 km down-dip and possibly 600 km along-strike, and if the plate slips in 10 m ruptures it could do so every 1200 years in a M~9 earthquake. No great earthquake has occurred since 1492, since when ~4 m of potential slip has developed, but should slip occur on just 10% of the hypothesized décollement (100x150 km) it could do so now in an Mw=8.2 earthquake. In that a potential Mw>8 earthquake poses a future seismic and tsunami threat to the Caribbean it is important to examine whether great earthquakes have occurred previously near the NW Venezuela coast. It is possible that creep accommodates the entire convergence signal, since there is no suggestion from microseismicity for an abrupt locked-to-sliding transition, as, for example, signifies its location in the Himalaya. An alternative measure of future potential seismic energy release is to identify the locus and rate of present-day strain contraction. To this end, Venezuelan, Colombian and US (CU and UNAVCO) investigators are installing an array of more than a dozen continuous operating

La investigación de tipo exploratorio adoptó un muestreo no probabilístico por conveniencia. La muestra resultó de ciento sesenta y ocho personas (168 entre encuestas auto suministradas y vía correo electrónico.

Estos resultados revelaron importantes diferencias con un estudio previo realizado en el país. La causa puede deberse a la falta de un procedimiento muestral más representativo de ambos estudios, ya que hasta la fecha no se ha realizado un estudio de escala nacional para medir Personalidad de Marca. A pesar de ello, se consiguieron evidencias que los rasgos de personalidad alrededor de la dimensión “Emocionante” pudiesen ser explicativos de la personalidad del venezolano promedio, ya que además de su consistencia interna, presentan coincidencias con otros estudios empíricos de segmentación realizados en el país.

    Full Text Available The enzymatic modification of aminoglycosides by aminoglycoside-acetyltransferases (AAC, aminoglycoside-adenyltransferases (AAD, and aminoglycoside-phosphotransferases (APH, is the most common resistance mechanism in P. aeruginosa and these enzymes can be coded on mobile genetic elements that contribute to their dispersion. One hundred and thirty seven P. aeruginosa isolates from the University Hospital, Cumana, Venezuela (HUAPA were evaluated. Antimicrobial susceptibility was determined by the disk diffusion method and theaac, aadB and aph genes were detected by PCR. Most of the P. aeruginosa isolates (33/137 were identified from the Intensive Care Unit (ICU, mainly from discharges (96/137. The frequency of resistant P. aeruginosaisolates was found to be higher for the aminoglycosides tobramycin and amikacin (30.7 and 29.9%, respectively. Phenotype VI, resistant to these antibiotics, was the most frequent (14/49, followed by phenotype I, resistant to all the aminoglycosides tested (12/49. The aac(6´-Ib,aphA1 and aadB genes were the most frequently detected, and the simultaneous presence of several resistance genes in the same isolate was demonstrated. Aminoglycoside resistance in isolates ofP. aeruginosa at the HUAPA is partly due to the presence of the aac(6´-Ib, aphA1 andaadB genes, but the high rates of antimicrobial resistance suggest the existence of several mechanisms acting together. This is the first report of aminoglycoside resistance genes in Venezuela and one of the few in Latin America.

    Full Text Available This paper addresses a core puzzle: why is continued citizen mobilization accompanied by growing disempowerment of those same citizens? Why do movements fail, leaders burn out and members disperse, and what are the implications of this organizational failure for demo¬cratic representation? Our consideration of the issues is rooted in a close examination of urban movements, mobilization, empowerment and disempowerment in the recent experience of Venezuela and Perú. The puzzle that concerns us is of course not limited to these two countries: it is common to all the Andean republics, and in different ways, to much recent experience of urban mobilization in Latin America and beyond. After a brief account of urban citizen move¬ments and politics in our two cases, we outline general reflections on the nature of empowerment and disempowerment, on the peculiar combination of strengths and weaknesses that mark many contemporary movements. A close examination of types of movements and their links with poli¬tical parties and protest follows. The character of city life is important here. We close with analysis of recent waves of urban mobilization in Perú (that sparked the ouster of president Alberto Fujimori and in Venezuela (both for and against president Hugo Chávez Frías, and with reflections on the likely future of empowerment and disempowerment for urban citizens and the implications of this perspective for democratic representationEste artículo plantea un puzzle principal: ¿por qué la movilización ciudadana continuada viene acompañada de un crecimiento del desempoderamiento de estos mismos ciudadanos? ¿Por qué los movimientos fracasan, los líderes se desgastan y los miembros se dispersan, y cuáles son las implicaciones del fracaso organizativo para la representación democrática?

The agent in the three hosts was identified as Leishmania braziliensis, subspecies braziliensis at least in man and donkey. The probable vector was Lutzomyia panamensis. No infection was found in a small sample of wild mammals examined. The outbreak was apparently linked with the importation of donkeys with ulcers, from endemic areas. The Authors call attention to the fact that not only in the foci of "uta", but also in areas of the other forms of American cutaneous leishmaniasis, dogs are frequently found infected. They emphasize the necessity of searching for the infection in donkeys and of performing hemocultures and xenodiagnosis with sandflies in human, canine and equine cases, to verify their possible role as sources of infection, and not merely as dead ends in the epidemiological chain of the disease.Durante um surto de leishmaniose tegumentar em Las Rosas, localidade previamente não endêmica do Estado Cojedes, Venezuela, 12,9% dos habitantes, 7% dos cães e 21,4% dos asnos (Equus asinus apresentavam lesões com parasitos.

    Universal access to healthcare has assumed renewed importance in global health discourse, along with a focus on strengthening health systems. These developments are taking place in the backdrop of concerted efforts to advocate moving away from vertical, disease-based approaches to tackling health problems. While this approach to addressing public health problems is a step in the right direction, there is still insufficient emphasis on understanding the socio-political context of health systems. Reforms to strengthen health systems and achieve universal access to healthcare should be cognizant of the importance of the socio-political context, especially state-society relations. That context determines the nature and trajectory of reforms promoting universality or any pro-equity change. Brazil and Venezuela in recent years have made progress in developing healthcare systems that aim to achieve universal access. These achievements are noteworthy given that, historically, both countries had a long tradition of healthcare systems which were highly privatized and geared towards access to healthcare for a small segment of the population while the majority was excluded. These achievements are also remarkable since they took place in an era of neoliberalism when many states, even those with universally-based healthcare systems, were moving in the opposite direction. We analyze the socio-political context in each of these countries and look specifically at how the changing state-society relations resulted in health being constitutionally recognized as a social right. We describe the challenges that each faced in developing and implementing healthcare systems embracing universality. Our contention is that achieving the principle of universality in healthcare systems is less of a technical matter and more a political project. It involves opposition from the socially conservative elements in the society. Navigation to achieve this goal requires a political strategy that

    The leaves and inflorescences of five species of Tagetes, family Asteraceae, were collected from different locations in Mérida state, Venezuela, and their essential oils analyzed by GC and GC/MS. Several differences were observed in the composition of these oils, mainly regarding the major components, which for T. caracasana were trans-ocimenone (64.3%) and cis-tagetone (13.7%), and for T. erecta, piperitone (35.9%) and terpinolene (22.2%). High amounts of trans-anethole (87.5%) and estragole (10.7%) were observed in T. filifolia, while T. subulata essential oil contained terpinolene (26.0%), piperitenone (13.1%) and limonene (10.8%). For T. patula, two different oil samples were analyzed, leaves (TPL) and inflorescences (TPI). The TPL oil showed terpinolene (20.9%) and piperitenone (14.0%) as main components, while the TPI sample was composed mainly of beta-caryophyllene (23.7%), terpinolene (15.6%) and cis-beta-ocimene (15.5%).

    Full Text Available Caseous lymphadenitis (CL is a chronic infectious disease caused by Corynebacterium pseudotuberculosis; it affects small ruminants and generates economic loss due to a reduction in weight, reproductive performance, milk and wool production forfeiture, and depreciation of skins. Given the socio-economic importance of goat production in the Falcón state (Venezuela, this research aimed to epidemiologically characterize the disease in herds in the Paraguaná peninsula. The research is descriptive. Field work lasted six weeks, during which superficial lymph nodes were inspected, and 71 samples of purulent discharge were obtained from animals suspected to suffer from CL, according to their clinical manifestations. Back in the laboratory, specimens were bacteriologically analyzed; C. pseudotuberculosis isolates were compared with the reference strain ATCC 19410. The only risk factor detected for CL (p < 0.05 was the origin of goats by production units; those with the highest prevalence were located in the municipality of Falcón. Injuries in subscapular lymph nodes were the most frequent (p < 0.05 among the diagnosed animals. Penicillin, trimethoprim-sulfamethoxazole, and novobiocin-resistant strains were identified. These results are important to raise awareness among producers, given that this activity is of vital importance for the region and in many cases ignorance on the subject was evidenced.

    The status of American cutaneous leishmaniasis was investigated from 1985 to 1991 to provide an epidemiologic characterization of the disease in Bergantin, a rural community in the northeastern part of Anzoátegui State, Venezuela. The study revealed the presence of the infection during the period analyzed, with an average incidence of 50.2 cases per 10,000 inhabitants and this number has increased 1.5 times during the last two years. Three villages where clinical cases had been recorded were selected for a comparison of their prevalence data. These villages comprise the human population in the high and low altitude limits of Bergantin. Immunologic assessment of the inhabitants used two different antigen preparations to examine responses to parasites associated with the cutaneous and visceral forms of the disease. The leishmanin skin test (LST) was used in a sample of 276 individuals (46.3% of the inhabitants) and resulted in an overall positivity of 16.7%. The percentage of LST positivity varied with age and sex, yet analysis of this response and the prevalence for each village reflected the specific characteristics of these localities. La Montaña, situated at 800 meters above sea level, had the highest prevalence (800 cases per 10,000 inhabitants) and the most positive LST response (21.2%) in comparison with the two other villages situated at a lower altitude (300 meters above sea level).

    Full Text Available In today’s world most of the countries are following the market rule to determine their economic determinants with some to follow the mixed role of the government. There are a very few countries or states that are following the socialistic nature of development. One such country is Venezuela which has a long history of socialism and the degree of socialism got magnified under the regime of Hugo Chavez. The last election result in favour of Chavez has put some questions before the economists and politicians regarding its grounds. The present study has been framed in line with examining whether the role of economic factors have done the trick for Chavez to regain the presidential power. The study for the period of 1998-2010 has observed that the country has suffered in major economic factors compared to two Latin heroes Brazil and Argentina, albeit he has won the election. The study further observed that there are certain political grounds that played role for the favourable verdict.

    With the purpose of determining antibodies prevalence against Venezuelan Equine Encephalitis Virus in the population of Puertos de Altagracia and Sabaneta de Palmas of Miranda county, Zulia State, Venezuela, 199 subjects were studied: 57 from Puertos de Altagracia and 142 from Sabaneta de Palmas. They were classified in older (42.78%) and younger (57.2%) than 15 years. The blood specimens were processed for Hemagglutination Inhibition Test using EEV antigen Goajira strain at pH 6.5. We found that all 57 specimens from Puertos de Altagracia were negative, whereas of 142 specimens from Sabaneta de Palmas 17 were positive (11.97%). Of these, one was from a subject less than 15 years-old (5.85%) and 16 from individuals more than 15 years-old (94.15%). Positive titers were higher than 1:160 in 80% of cases. Being Sabaneta de Palmas one of the most affected areas in the 1962 epidemic in the Miranda county and keeping the affected ones high positivity with elevated titers, we conclude that this population could represent an enzootic zone similar to Paez county where a similar situation, of high positivity and elevated titers, many years after the last epidemic occurred in that area, has been described.

    Full Text Available Fluorescent (acridine orange microscopical examination of capillary centrifuged blood (quantitative buffy coat [QBC®] analysis and Giemsa stained thick blood smears (GTS were compared for diagnosis of malaria in blood specimens from adults living in malaria transmission areas of the States of Bolivar and Amazonas in southeastern and south Venezuela, respectively. Of a total of 198 GTS examined, 95 subjects (48% showed parasitaemia. Among the 95 blood films with a positive GTS, 94 were judged positive by the QBC. However, positive QBC tubes were found in 29 out of 103 blood specimens with a negative GTS. Thus, relative to a GTS standard, the sensitivity and specificity of the QBC-test was 99.2% and 72%, respectively. Young trophozoites of Plasmodium vivax and P. falciparum could not be distinguished with certainty. It is confirmed that the QBC offers many advantages compared with the standard diagnosis of malaria parasites, specifically in the speed of staining and ease of interpretation. However, in places where P. falciparum and P. vivax occur, species and stage differentiation should be confirmed with the GTS.

    This paper presents the results of the project of cyclic hot water injection carried out in the Morichal field, Monagas State, Venezuela, by Phillips Petroleum Co. A total of 66 billion btu of heat was injected in 21 wells for a total increment of 560,000 bbl in petroleum production. This increment in the production of petroleum was due to 2 reasons: (1) the cleanness of the formation around the wells, of the tube's perforations, and of the gravel packing caused by the removal of asphalt deposits, carbonates, etc.; and (2) reduction of the viscosity of petroleum caused by the increase of the temperature. The best results were obtained from wells in which production had decreased from plugging of flow channels in the surrounding formation, wells in good mechanical conditions and wells which were adjacent to undeveloped areas. The experience of this project points out that: (1) during a second cycle of stimulation, a production increment is obtained of approx. 80% as compared to that of the first cycle; (2) at least 2 billion btu of heat has to be injected per cycle; and (3) the wells that have a bad response to a cycle of stimulation should not be stimulated again unless the cause of bad response is eliminated or corrected.

    Paleoseismic studies have proved to be a powerful tool in seismic hazards assessment by he contributing to asses the seismogenic potential of a given fault by expanding the time window o seismic activity beyond the limits of historical and instrumental seismicity. Trenching has been an essential tool for paleoseismic studies in Venezuela. The first paleoseismic trenching project in Venezuela goes back to 1968 when Compania Shell de Venezuela retained the services of Woodward Clyde and Associates,(WCA), USA to asses the seismic integrity of the earthen dikes of Costa Oriental of Lake Maracaibo Protection System (COLM) in western Venezuela. The study was carried out under the general coordination of this author. An important part of this project included a seismology and seismic geology study under the direction of Geologist L.S. Cluff. This was the first ever study undertaken in Venezuela and included two excavations across the Oca Fault north of the city of Maracaibo. After several years of inactivity, FUNVISIS (The Venezuelan Foundation for Seismological Research) carried out in 1980 a seismic hazard (SHA) for the Uribante Caparo Hydroelectric Project southwest Venezuela. In 1989, MARAVEN, an operating company of PETROLE0S DE VENEUELA S.A. (PDVSA) undertook the project of a products pipeline form Maracaibo to El Vigia, south of Lake Maracaibo. Again, FUNVISIS was contracted to carry out a SHA, which included the digging of 5 trenches, which were supplemented with five more trenches for the COLM project. Trenching activity contined in Venezuela in the framework of SHA project, under the direction of Dr. Audemard. In 2001 Venezuelan trenching experience was exported to the neighboring Colombia as e Dr. Audemard t undertook a palaoseismicity project which included the digging of five trenches. In conclusion, paleoseismicty studies have given us the possibility of extending the scope of both instrumental and historical seismicity by some 10,000 years, trenching has

Los datos geologicos e hidrologicos del norte del rio Orinoco proceden de la digitalizacion de mapas geologicos en papel a escala 1:500.000. Estos datos fueron integrados con el mapa geologico digital del Escudo de Guayana Venezolano, a su vez derivado de hojas en papel a escala 1:500.000. La informacion sobre los tipos de fallas mostrados en el mapa es igual que en las fuentes originales. Los poligonos geologicos fueron atribuidos por edad, litologia y nombre de la unidad siguiendo el Codigo geologico de Venezuela. Se incorporaron revisiones significativas de la geologia de la Cordillera de la Costa a partir de las nuevas hojas integradas a escala 1:25.000. Toda esta informacion geologico-estructural se sobrepuso a una imagen de relieve sombreado, producida por el procesamiento de los datos de radar interferometrico con 90 m (3 arcosegundos) de resolucion espacial obtenidos por la mision topografica de radar del transbordador espacial (SRTM). Las areas de la base de datos del SRTM carentes de informacion fueron llenadas por medio de la interpolacion de los datos de las celdas adyacentes. Para producir la imagen de relieve sombreado se uso una direccion de iluminacion de 315 deg con un angulo de 65 deg sobre el horizonte. La proyeccion usada en el mapa es conica equidistante, con latitudes de 4 y 9 deg norte como paralelos estandar y una longitud de 66 deg al oeste como meridiano central. Los datos en el mapa proceden primordialment de hojas a escala 1:500.000 y el producto esta preparado para una impresion optima en escala 1:750.000. Los usuarios pueden obtener ampliaciones mayores, sin embargo no se garantiza la precision del mapa a escalas mas detalladas. Especialmente en la region de Guayana, al sobreponer los mapas geologicos sobre la reciente imagen SRTM, se notan grandes discrepancias no sistematicas tanto en contactos como en fallas.

    Full Text Available RESUMEN: Partiendo de la afirmación de Levine y Molina (2006, según la cual la calidad de la democracia depende del funcionamiento de los procesos mediante los cuales la población selecciona y controla sus gobernantes, en este trabajo se examina el caso venezolano, haciendo especial énfasis en el análisis de la dinámica electoral del período marcado por la presidencia de Chávez (1999-2006. Dicho examen nos lleva a concluir que el régimen sociopolítico venezolano actual puede ser caracterizado más adecuadamente como un «régimen autoritario electoral», más que como una democracia representativa convencional. Los rasgos autoritarios del gobierno venezolano actual explicarían la baja puntuación obtenida por Venezuela en los índices de Freedom House. Sin embargo, este examen también nos lleva a considerar la pertinencia de los supuestos de la calidad de la democracia en el contexto de un cambio de régimen que explícitamente se aleja de las aspiraciones e ideales que sustentan el concepto, dimensiones e indicadores de la calidad de la democracia propuestos.ABSTRACT: Taking off from the affirmation by Levine and Molina that «the quality of democracy depends on the operation of procedures whereby the population selects and controls its government», this article examines the dynamics of elections during the Presidency of Chávez, (1999-2006. This examination leads to the conclusion that the current regime is better characterized as «an autoritarian electoral regime» than as a conventional representative democracy. This re-definition explains the low scores obtained by Venezuela both in Freedom House. At the same time, this study throws light on the bases of democracy and of definitions of quality of democracy in a regime that explicitly rejects the very ideals and aspirations that underlie the definitions, dimensions and indicators of democracy itself.

    Full Text Available El Joropo es una expresión de arte popular en permanente evolución, originalmente una fiesta campesina o pueblerina que integra poesía, canto, música y danza en un sistema de creatividad improvisatoria sobre estructuras establecidas y parámetros definidos de estilo. El Joropo se caracteriza por un sistema de estructuras cristalizadas a lo largo de la historia a partir de canciones y danzas tradicionales que se erigieron en formas musicales, sirviendo como base para a variantes en la letra, o convirtiéndose en formas puramente instrumentales. El Joropo es una tradición que abarca casi la totalidad del territorio venezolano y al menos la cuarta parte del territorio colombiano. En Venezuela el Joropo es considerado el baile nacional por excelencia y existen tres tipos de Joropo clasificados por regiones con importantes variantes de instrumentación y estilo: el Joropo Oriental, el Joropo Central y el Joropo Llanero. Solamente el Joropo Llanero, extendido alrededor de la cuenca central del Orinoco, es común a Colombia y Venezuela, siendo el más difundido de todos, tanto por la amplia discografía y radiodifusión como por la abundancia de festivales, concursos y torneos que involucran a ambos países. Además es notable el auge y desarrollo urbano que ha tenido esta música en los últimos años en las respectivas capitales. Sus orígenes se remontan a las músicas ibéricas del Siglo XVII y XVIII, tales como el múltiple Fandango, las Folías, Peteneras, Jotas y Malagueñas andaluzas, sazonadas con la influencia de ocho siglos de dominación árabe y posteriormente transformadas en América con el mestizaje de elementos africanos e indígenas, bajo el sol abrasador de la Cuenca del Orinoco y la vastedad infinita de sus horizontes y llanuras. Los antecesores del Joropo incluyen la música de marineros y trovadores que llega en los galeones provenientes de España, transformándose en música arraigada en el suelo americano y dando lugar a

    The Caribbean waters of Venezuela are composed by a large variety of habitats, with over 2800 km of coastline, islands, and islets. This area is a transitional zone between two main biogeographic provinces, the Caribbean and the Brazilian, separated by the fresh water outflows of the Orinoco and Amazon rivers, and is therefore expected to be an area of high species diversity. However, concerning the study of molluscs, Venezuela is probably the poorest known region in the Caribbean. The best compilation of opisthobranch species known in Venezuela was produced almost a decade ago, mentioning the occurrence of 57 species, plus seven determined only to genus level. In this work, 134 species are reported for Venezuela (71 are illustrated), representing about 40 % of the entire diversity of opisthobranchs known in the Caribbean. Among the species occurring in Venezuela, 49 have here the southern limit of their distribution range and only one the northern limit. Forty-six species are recorded for the first time to the country and one is a new record for the Caribbean Sea, namely Placida cremoniana. In addition, the distribution and ecology of the species are given based in literature and new data.

    Chemical, paleontological, and mineralogical analyses of a 7.5-meter core from the middle of Lake Valencia, Venezuela, have provided information on the paleoclimatic history of this low-elevation, low-latitude site for the last 13,000 years. The data show that dry climates existed in this region from 13,000 years before present (B.P.) until about 10,000 years B.P. The Lake Valencia Basin was occupied by intermittent saline marshes at that time. About 10,000 years B.P., a permanent lake of fluctuating salinity formed and arboreal plant communities replaced the earlier dominant xeric herbaceous vegetation and marsh plants. By 8500 years B.P., Lake Valencia reached moderate to low salinities and discharged water; the modern vegetation became established at that time. After 8500 years B.P., the lake twice ceased discharging as a result of reduced watershed moisture. The second of these drying episodes is still in progress and has been aggravated by human activities in the watershed.

    Full Text Available Venezuela pese a los innumerables dotes naturales no ha podido alcanzar el anhelado desarrollo, tampoco el bienestar de todos sus habitantes, en parte porque sus acciones y prácticas económicas no se han fundamentado en el desarrollo sustentable, su comercio exterior se limita a la exportación de materias primas básicas sin mucho valor agregado cuya explotación intensiva incrementa la vulnerabilidad ecológica irreversible. En el presente trabajo se analiza la economía venezolana en el marco del desarrollo sustentable, vinculando su participación en el comercio exterior con el desarrollo sustentable. Se recomienda la urgente reducción de la dependencia petrolera, la diversificación económica y de exportaciones, para participar en el comercio internacional de forma dinámica con productos de alto valor agregado. El reto son los procesos de liberalización comercial y mundialización que promueva la sustentabilidad ecológica y el desarrollo humano equitativo, integrando mundialmente las políticas ecológicas y comerciales, dado que el comercio internacional no necesariamente eleva la calidad de vida y la salud del planeta, por el contrario, todo depende del uso eficiente de los recursos para crear riquezas en concordancia con la protección del medio ambiente.

    Soil, waste rock and mud from mercury-gold amalgamation mining areas of El Callao (Venezuela) are highly enriched in Hg (0.5-500 microg g(-1)) relative to natural background concentrations (mining districts (>100,000 ng m(-2) h(-1)). The results from this study also show that Hg emissions from the soil are influenced by solar radiation, soil temperature and soil Hg concentration. Our data suggest that solar radiation may be the dominant factor affecting Hg degrees emission since the major species of mercury in polluted soil is Hg degrees (85-97% of total Hg). The simple release of Hg degrees vapor is probably the dominant process occurring with incident light in the field. The apparent activation energy for mercury emission indicates that the volatilization of mercury mainly occurred as a result of the vaporization of elemental mercury in soil. The degree of Hg emission differed significantly among the soil sites studied, which may be due to variations in soil texture, organic matter content and soil compaction.

    Most of the anthropometric standards are derived from adult populations but not from older subjects, so their use to evaluate the nutritional status in the elderly may not be the most appropriate. In this sense, the anthropometric characteristics and their relationship to sex and age in a cross-sectional sample of 809 Venezuelan subjects (370 males and 439 females), aged 60 to 102 years old, randomly selected from a elderly institution-alised population were studied. The results indicate that anthropometric variables show different degrees and signs of sexual dimorphism. Males presented higher stature, weight, waist and calf circumferences and higher bone diameters, while females have higher hip and thigh perimeters, and bigger trunk and extremities skinfolds. Independently of the changes observed in these variables with age, the difference spread between the sexes tends to stay and even to increase with age in the height and weight, in hip perimeter and in thigh and calf skinfolds; while, on the contrary, they attenuate in waist perimeter and in triceps, subescapular and suprailiac skinfolds. Males and females appear to be more similar for these variables in the advanced ages. In general, these results could be used as reference elements for similar researches in Venezuela, due to the low number of studies developed in the country in older populations

    Overweight and obesity are a public health problem worldwide affecting adults and children as well. The aim of this study was to assess overweight, lipid profile and cardiovascular risk ratios in 390 preschool children from low socio-economic level from Valencia, Venezuela. Nutritional anthropometric evaluation measured by body dimensions, and serum determination of cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol and cardiovascular risk factors, were determined. 95% of the children were in relative and critical poverty. 14.3% of undernutrition and 20.8% of overweight was found. Lipid profile was in normal range, with no significant differences by sex, but higher values for HDL-cholesterol and risk ratios were found in children aged 1 to 3.99 years. Even though no differences were found by nutritional status, overweight children had higher values for lipids, except HDL-cholesterol. 6.3% of overweight children had cholesterol > or =170 mg/dL, 16.5% LDL-cholesterol > or =110 mg/dL, 40.5% triglycerides > or =75mg/dL and 100% HDL-cholesterol Nutritional and educational intervention should be addressed.

    Bulk geochemical parameters and organic matter biomarkers in a short, high resolution gravity core (Lake Valencia, Venezuela) were examined to reconstruct anthropogenic impacts on the lake's conditions. During the period of ca. 1840-1990, sedimentary organic matter was characterized by high contents of total organic C (TOC) and total N (TN), low TOC/TN values as well as relatively enriched {delta}{sup 13}C and {delta}{sup 15}N signals, suggesting a primary autochthonous (algae and macrophytes) organic matter origin. The occurrence of large amounts of C{sub 23} and C{sub 25} relative to C{sub 29} and C{sub 31}n-alkanes indicated substantial inputs from submerged/floating macrophytes. The variations of C{sub 32} 15-keto-ol, tetrahymanol, diploptene, C{sub 32} bishomohopanol, 2-methylhopane, dinosterol and isoarborinol concentrations over the investigated period record changes in the planktonic community structure, including Botryococcus braunii, bacteriavore ciliates, cyanobacteria, Eustigmatophytes and dinoflagellates. A principal shift occurred in the 1910s when cyanobacteria and dinoflagellates became more abundant at the expense and decline of B. braunii and Eustigmatophytes, likely related to increasing anthropogenic activity around the lake. A second shift (less obvious) occurred in the 1960s when cyanobacteria became the sole predominant planktonic class, coinciding with further deterioration of lake conditions.

The methodological treatment part of the approach of the premise: the new model of university education which is be built, is due to the crisis of the instrumental cognitive model established in the Constitution of the Republic of Venezuela (1961, its laws and regulations. To the triangular three categories arises, as an added value, conceive education through a transdisciplinary process, sustained in the first instance by the legal system to give realization and synchronization in time and movement. In the case of Venezuelan education, it is concluded that they have not been produced significant changes that indicate us that we are in the presence of a new model of education. University education is tied to the cognitive model instrumental, preventing any change it from her womb is intended to promote, so that the new law of university education and the new model of education remain deferred.

    1976-12-01

    The purpose of this report is to describe isolations of Venezuelan (VEE) and Eastern (EEE) Equine Encephalitis virus made in the lowland moist tropical forest of the Catatumbo region on the southwestern part of the State of Zulia, Venezuela. We have isolated four strains of EEEV from sentinel hamsters exposed at Caño Mocho and Madre Vieja sites in 1973 and 1974, and three strains of EEEV in Hacienda (Hda.) Las Nubes in 1975. Both viruses were recovered during silent interepidemic periods and we believe these viruses are maintained in this region in sylvatic conditions. The recovered virus strains were detected within 24 to 48 hours, both in SMB and Vero Cell monolayer cultures and the sentinel hamsters yielded virus infectivities up to 10(4) PFU ml. Our VEEV isolate (IVIC PAn 23645-47), recovered during the silent interepizodemic period had an elution profile on the hydroxylapatite column corresponding to that of a I-D (VEEV-3880) or a I-E (VEEV-63A216) 'enzootic' subtype. However, considering other in vitro criteria (KHI; HA pH 5.8-6.0; small plaque size in Vero monolayers with suitable overlay media), this later and other previous isolates had some very distinct properties of the 'epizootic' strains. Thus, the evidence suggests that in Venezuela the VEEV cycle in nature is maintained either by the so called 'enzootic' and/or 'epizootic' virus types, or the virus population of the isolates have particular in vitro properties which do not correlate to the virulence markers in vivo. We consider this important question must be further clarified, and in addition, the isolation of three strains of EEEV are reported; this is the first report of the presence of this virus in Venezuela. Although the EEEV isolates may be of the South American type, they must be considered as potentially dangerous in the case of outbreaks.

    Full Text Available The 1999 Constitution of the Bolivarian Republic of Venezuela (CBRV recognizes Indigenous Rights; among them, the territorial claims. In agreement with what is stated in the article 119 of the Magna Carta, the right to the territory of these populations is exercised through the public policy of demarcation, which is understood as the process in which its territorial space is disclaimed, made by the State in participation with the peoples and communities to be demarcated, subsequently to entitle the collective ownership for these human beings groups. Fifteen years after the Constitution was approved, this process of delineation has been slow and misleading. This delay has caused that in the present, these human beings groups are being stalked by outside interests (illegal mining, development projects, irregular forces, among others who threaten their existence as distinct cultures; since the right to territory is a fundamental human right for their survival. This article is the result of a field research. In the first part, the study analyzes the Organic Law of Indigenous Peoples and Communities (LOPCI (2005 in Venezuela, with the purpose of clarifying at what stage the territorial demarcation process is paralyzed; and as a result, it describes how many communities and indigenous peoples have been demarcated and entitled from 2005 to 2014.

El abordaje se enmarcó con una metodología de tipo descriptiva mediante la revisión de fuentes documentales. Por su parte, los hechos estilizados permiten evidenciar el comportamiento de la economía venezolana en el período de estudio y los elementos fundamentales de incidencia sobre el crecimiento económico. Finalmente se concluyó que los variantes e inestables niveles del crecimiento económico en los últimos años, estuvieron influidos generalmente por el gasto público auspiciado por los altos ingresos petroleros. La economía venezolana se caracteriza por tener un sector productivo “estrangulado”, no obstante, los últimos cinco años del período estudiado, el PIB ha presentado una propensión decreciente generado por la disminución del crecimiento económico. En suma, no se ha logrado subsanar y erradicar los problemas sociales más importantes en la economía venezolana como la pobreza, la inflación, el desempleo, entre otros; muchas de estas dificultades inciden directa y proporcionalmente sobre el bienestar social y por ende sobre el desarrollo humano, concluyendo que los beneficios económicos de los períodos de bonanza, no se trasladan en significativas mejoras de la calidad de vida.

The name of this event is "Encounters with Physics, Chemistry, Mathematics, and Biology" (hereinafter "Encounters with Science"), and it integrates these disciplines as well as Astronomy. Its main purpose is that young minds can become familiar with the methods of science inquiry and reasoning, and can understand the concepts and processes of the sciences through thoroughly prepared experiences. This flourishing program is continuing to grow and to become strong. As a matter of fact, in its sixth edition (2005), the number of high and elementary school students coming from all over the country, has reached the outstanding number of nine thousand. Among all the experiences that the students could be engaged in were many involving Astronomy. These experiences were prepared by professors, together with graduate and undergraduate students, who are pursuing their degrees in all branches of science including astronomy. Although there is this incredible team of faculties and graduate and undergraduate students working together; the target is the students of the high and elementary schools. We certainly focus on the engaging and encouraging of students to experience scientific work first hand. Additionally, our professors have prepared an excellent didactic material that can, together with the hour/class teaching, prepare high school and elementary school students for a better understanding of science; particularly, helping in this way for a better education in Astronomy. The main event of the Encounters lasts five days in the School of Science of ULA, but subsidiary events are spread all over the year and around the country. As a successful program, it can be interesting to see if other countries can adopt this method to recruit or to trigger the interest of students to pursue their

    Full Text Available Se realizó un estudio epidemiológico descriptivo de corte transversal, con el objetivo de determinar la morbilidad oculta por parasitismo intestinal en Lagunita, municipio Girardot, Venezuela; en el período de enero a octubre de 2009. El universo fue de 286 niños, lo que se corresponde con la población total del grupo de edad de menores de 15 años. De estos se seleccionaron por muestreo aleatorio simple 43 pacientes, a los que se les aplicó un cuestionario y se confeccionó una guía de observación, para describir los factores epidemiológicos que influyen en la infestación por parasitismo intestinal. Además, se les realizaron análisis de las heces fecales seriadas para el diagnóstico del parasitismo. El método estadístico fue el cálculo de las frecuencias absolutas y relativas. A través del estudio de las heces fecales seriadas se obtuvo que 27 pacientes tenían parasitosis intestinal, para una morbilidad de 62,79%, con una mayor incidencia en los niños de cinco a nueve años de edad. El sexo femenino fue el más afectado. Los factores epidemiológicos que más influyeron fueron: los malos hábitos higiénicos personales, el entorno desfavorable y el consumo de agua no potable; existió relación entre el nivel socioeconómico, los factores epidemiológicos y la morbilidad por parasitismo intestinal. Predominó la parasitosis por Entamoeba Histolytica, con 11 casos, para un 40,74%. La diarrea, las molestias abdominales y la pérdida de apetito constituyeron los principales síntomas

    Full Text Available As in many other Spanish Empire’s provinces abroad, Venezuelan colonial society was based on hierarchical values and inegality. This was a direct consequence of translating Spain’s mores and forms to its American territories during trhe Conquest period. A creole nobility thus appeared that could not but behave accordingly to the values and principles of the Ancien Regime. Many creole noblemen, however, embraced the independentist movement and supported the political changes that put an end to the colonial order and gave way to a republican one. How this process same about, what contradictions emerged as it evolved and what ultimate effects —if any— it had upon the Provincia de Caracas is the main subject of this paper

    En Venezuela, como en otras provincias ultramarinas, se constituyó una sociedad jerárquica y desigual, consecuencia directa de la traslación y adecuación a estos territorios de las formas y procederes sociales existentes en España en el momento de la conquista. Como consecuencia de este proceso, se formó una nobleza criolla que actuó de acuerdo con los valores y principios jerárquicos de la sociedad del Antiguo Régimen. Muchos de los hombre pertenecientes a los sectores privilegiados de la sociedad se sumaron a la causa de la Independencia y apoyaron el cambio político que puso fin a la sociedad antigua y dio paso a la instauración de un orden republicano. Cómo se dio este proceso en la provincia de Caracas, cuáles fueron sus contradicciones y qué efectos tuvo sobre la sociedad resultante, es el objetivo del presente artículo.

    Merida Andes (MA) is one of the most important orogenic belt in Venezuela and represents the northern culmination of South America Andes. During the last 60 years, several models have been proposed to explain the shallow and deep structure, using different geological, geophysical, seismological, geochemical and petrologic concepts; nevertheless, most of them have applied local observation windows, and do not represent the major structure of MA. Therefore, a multidisciplinary research group, coordinated by FUNVISIS, in close cooperation with UCV, ULA and PDVSA, is proposed in order to get the outlined goals in the project entitled GIAME ("Geociencia Integral de los Andes de MErida") was established, which aims to generate a lithospheric scale model and the development of a temporal dynamic model for the MA. As a base for lithospheric investigations of the Merida Andes, we are proposing three wide angle seismic profiles across the orogen on three representative sites, in order to determine the inner structure and its relation with the orogen's gravimetric root. To the date, there are no seismic studies at lithospheric scale which cross MA. The wide angle seismic will be complemented with the re-processing and re-interpretation of existing reflection seismic data, which will allow to establish a relationship between MA and its associated flexural basins (Maracaibo and Barinas-Apure basins). Depending on the results of the VENCORP Project (VENezuelan COntinental Reflection Profiling), which might show some reliable results about crustal features and Moho reflectors along three long seismic profiles at Caribbean Moutain system, a reflection seismic profile across the central portion of MA is proposed. Additional tasks, consisting in MA quaternary deformation studies, using research methods like neotectonics and paleoseismology, georadar, numerical modeling, cinematic GPS, SAR interferometry, thermocronology, detailed studies on regional geology, flexural modeling

    seroprevalence, between 1988 to 1992, was 1.20%(1.09 - 1.94%, with geographical variations between localities in several Stales. States with higher prevalence rates are located in the western and central part of Venezuela: Portuguesa, Lara, Trujillo, Cojedes and Carabobo. Due to difficulties in obtaining incidence rates for Chagas disease, it seems proper to use prevalence rates due to its greater stability; and in the specific case of Venezuela, due to a lesser severity and a higher survival of this disease at present. Considering that there is little to be offered to the seropositive individual, repeatibility is avowed for serological diagnosis. Specificity should be strived for in the light of lower prevalence rates at present.

    Full Text Available Resumen Venezuela transita desde 1999 por un proceso propio de transformación impulsado por el Estado. La aprobación de políticas alternativas plasmadas en una nueva constitución, en las leyes aprobadas en el marco de ésta y en otros documentos, dan cuenta de una nueva orientación dirigida a romper con las tendencias neoliberales de los 90 del pasado siglo. Desafortunadamente, en cuanto a los procesos de gestión, es evidente la presencia de viejas prácticas que obstaculizan los avances, aunque se maneja la hipótesis de que en este contexto existen algunos procesos innovadores vinculados a las políticas alternativas. El propósito de este trabajo es explorar la presencia de estos procesos en la gestión pública venezolana, vinculados a la nueva política. La metodología consistió en el análisis de documentos oficiales y fuentes secundarias, así como entrevistas abiertas a actores que han estado cerca de algunos de los procesos innovadores. Los resultados dan cuenta de: 1 Procesos de desconcentración flexibles que acerca el Estado al ciudadano; 2 Comunicación argumentativa a los ciudadanos, sobre las nuevas políticas; 3 Un sistema de participación que potencia la incorporación de los ciudadanos en la defensa de los intereses colectivos; 4 Estrategias de articulación sectorial e institucional; 5 Procesos de incorporación del sector privado a las políticas de inclusión social; 6 Sistemas de compras y financiamiento como promotores de la economía social.

  19. Politics of oil in Venezuela: A decision-making analysis of PDVSA's internationalisation policy

    Science.gov (United States)

    Baena, Cesar E.

    The high degree of international vertical integration achieved by the Venezuelan state oil enterprise, Petroleos de Venezuela S.A. (PDVSA), has placed it among the most important oil multinationals (MNs). The policy of creating downstream outlets through the establishment of foreign direct investments (FDIs) in the form of refinery assets was given the term of 'internationalisation'. By analysing PDVSA's internationalisation policy, the thesis explores the difficulties encountered by a major state-owned enterprise (SOE) from a developing country in its efforts to grow beyond national borders. The study focuses on the impact of democratic bargaining on the process of oil policymaking in Venezuela, stressing the constraints posed by politics on PDVSA's efforts to expand its foreign operations. Specifically, the study examines the intricate policymaking process that shaped the origins and the development of PDVSA's internationalisation policy, underlying the events and factors that influenced each one of its three distinguishable phases: adoption, formulation, and implementation. The tensions between politics and corporate strategy are highlighted at the core of the policymaking process. The study also looks at the relationship between the oil industry and the other two key decision-making centres involved in the oil policymaking process: the executive and Congress. In exploring the ways in which each one of them sought to influence policy outcome, the study attempts to gain insight into the main factors that prompted the tensions among the policy actors involved. Three environments, or pressure-generating centres, constantly exert influence on the oil industry: the oil market, the political context and the government's financial situation. By seeking to determine the industry's response to their pervasive influence on policy formulation and implementation, this research ascertains the extent to which these variables influenced the decision-making process that

L’affichage de nouvelles volontés politiques sur la scène régionale et internationale, sous l’impulsion du président Chavez, a perturbé le marché touristique national qui était dominé pour les clientèles nord-américaines ; le Venezuela apparaît désormais aux yeux des Etats-Unis comme un pays à risque, instable. C’est dans ce contexte que s’inscrit le « Programa Andes Tropicales » [PAT] qui soutient le  développement rural dans les parcs nationaux ; ce programme repose sur la participation des populations locales et leur implication dans les politiques de conservation des ressources naturelles et culturelles sources de revenus.

    Long-term demographic data are valuable for assessing the effect of anthropogenic impacts on endangered species and evaluating recovery programs. Using a 2-state open robust design model, we analyzed mark-recapture data from green turtles Chelonia mydas sighted between 1979 and 2009 on Aves Island, Venezuela, a rookery heavily impacted by human activities before it was declared a wildlife refuge in 1972. Based on the encounter histories of 7689 nesting females, we estimated the abundance, annual survival, and remigration intervals for this population. Female survival varied from 0.14-0.91, with a mean of 0.79, which is low compared to survival of other populations from the Caribbean (mean = 0.84) and Australia (mean = 0.95), even though we partially corrected for tag loss, which is known to negatively bias survival estimates. This supports prior suggestions that Caribbean populations in general, and the Aves Island population in particular, may be more strongly impacted than populations elsewhere. It is likely that nesters from this rookery are extracted while foraging in remote feeding grounds where hunting still occurs. Despite its relatively low survival, the nesting population at Aves Island increased during the past 30 years from approx. 500 to >1000 nesting females in 2009. Thus, this population, like others in the Caribbean and the Atlantic, seems to be slowly recovering following protective management. Although these findings support the importance of long-term conservation programs aimed at protecting nesting grounds, they also highlight the need to extend management actions to foraging grounds where human activities may still impact green turtle populations.

    To determine the predictive power of various anthropometric indices for the identification of dysglycemic states in Maracaibo, Venezuela. A cross-sectional study with randomized, multi-staged sampling was realized in 2230 adult subjects of both genders who had their body mass index (BMI), waist circumference (WC) and waist-height ratio (WHR) determined. Diagnoses of type 2 diabetes mellitus (DM2) and impaired fasting glucose (IFG) were made following ADA 2015 criteria. ROC curves were used to evaluate the predictive power of each anthropometric parameter. Area under the curve (AUC) values were compared through Delong's test. Of the total 2230 individuals (52.6 % females), 8.4 % were found to have DM2, and 19.5 % had IFG. Anthropometric parameters displayed greater predictive power regarding newly diagnosed diabetics, where WHR was the most important predictor in both females (AUC = 0.808; CI 95 % 0.715-0.900. Sensitivity: 82.8 %; specificity: 76.2 %) and males (AUC = 0.809; CI 95 % 0.736-0.882. Sensitivity: 78.6 %; specificity: 68.1 %), although all three parameters appeared to have comparable predictive power in this subset. In previously diagnosed diabetic subjects, WHR was superior to both WC and BMI in females, and WHR and WC were both superior to BMI in males. Lower predictive values were found for IFG in both genders. Accumulation of various altered anthropometric measurements was associated with increased odds ratios for both newly and previously diagnosed DM2. The predictive power of anthropometric measurements was greater for DM2 than IFG. We suggest assessment of as many available parameters as possible in the clinical setting.

    2003-01-01

    The pristine nature of the Orinoco Delta of eastern Venezuela provides unique opportunities to study the geologic processes and environments of a major tropical delta. Remote-sensing images, shallow cores, and radiocarbon-dating of organic remains form the basis for describing deltaic environments and interpreting the Holocene history of the delta. The Orinoco Delta can be subdivided into two major sectors. The southeast sector is dominated by the Rio Grande-the principal distributary-and complex networks of anastomosing fluvial and tidal channels. The abundance of siliciclastic deposits suggests that fluvial processes such as over-bank flooding strongly influence this part of the delta. In contrast, the northwest sector is represented by few major distributaries, and overbank sedimentation is less widespread relative to the southeast sector. Peat is abundant and occurs in herbaceous and forested swamps that are individually up to 200 km2 in area. Northwest-directed littoral currents transport large volumes of suspended sediment and produce prominent mudcapes along the northwest coast. Mapping of surface sediments, vegetation, and major landforms identified four principal geomorphic systems within the western delta plain: (1) distributary channels, (2) interdistributary flood basins, (3) fluvial-marine transitional environments, and (4) marine-influenced coastal environments. Coring and radiocarbon dating of deltaic deposits show that the northern delta shoreline has prograded 20-30 km during the late Holocene sea-level highstand. Progradation has been accomplished by a combination of distributary avulsion and mudcape progradation. This style of deltaic progradation differs markedly from other deltas such as the Mississippi where distributary avulsion leads to coastal land loss, rather than shoreline progradation. The key difference is that the Orinoco Delta coastal zone receives prodigious amounts of sediment from northwest-moving littoral currents that transport

  7. Household energy use in urban Venezuela: Implications from surveys in Maracaibo, Valencia, Merida, and Barcelona-Puerto La Cruz

    Figueroa, M.J.; Sathaye, J.

    1993-08-01

    This report identifies the most important results of a comparative analysis of household commercial energy use in Venezuelan urban cities. The use of modern fuels is widespread among all cities. Cooking consumes the largest share of urban household energy use. The survey documents no use of biomass and a negligible use of kerosene for cooking. LPG, natural gas, and kerosene are the main fuels available. LPG is the fuel choice of low-income households in all cities except Maracaibo, where 40% of all households use natural gas. Electricity consumption in Venezuela`s urban households is remarkably high compared with the levels used in households in comparable Latin American countries and in households of industrialized nations which confront harsher climatic conditions and, therefore, use electricity for water and space heating. The penetration of appliances in Venezuela`s urban households is very high. The appliances available on the market are inefficient, and there are inefficient patterns of energy use among the population. Climate conditions and the urban built form all play important roles in determining the high level of energy consumption in Venezuelan urban households. It is important to acknowledge the opportunities for introducing energy efficiency and conservation in Venezuela`s residential sector, particularly given current economic and financial constraints, which may hamper the future provision of energy services.

    Full Text Available This article analyzes the changes in violence in Venezuela during the last forty years. It links the ups and downs of the oil revenues and the political crisis of the country to the changes in the homicide rates, which increased from 7 per 100 thousand inhabitants in 1970 to 12 in 1990, 19 in 1998 and 50 in 2003. The article characterizes Venezuela as a rentist society and shows its trajectory from rural violence to the beginning of urban violence, the guerilla movements of the 60s, the delinquent violence related to the abundance of oil revenues and the violence during the popular revolt and the sackings of 1989 in Caracas. After this, we analyze the coups d'état of 1992 and the influence the political violence exerted upon criminal violence. We describe the political and party changes in the country, their influence upon the stabilization of homicide rates since the mid-90s and their remarkable increase during the H. Chávez government. The article finishes with an analysis of the current situation, the official prohibition to publish statistics on homicides and with some thoughts about the perspective of greater violence in Venezuela.O presente artigo analisa as mudanças na violência ocorridas na Venezuela nos últimos quarenta anos, relacionadas com os altos e baixos da renda petroleira e com a crise política no país, fatos que contribuíram para um aumento nas taxas de homicídios: de 7 por cada cem mil habitantes em 1970 a 12 em 1990, 19 em 1998 e 50 no ano de 2003. O artigo caracteriza a Venezuela como sociedade rentista e, a partir daí, faz uma retrospecção cobrindo desde a violência rural até os inícios da violência urbana, o movimento guerrilheiro dos anos sessenta, a criminalidade resultando da abundância dos recursos petroleiros e a violência em decorrência da revolta popular e dos saques ocorridos em 1989 em Caracas. Em seguida são analisados os golpes de Estado de 1992 e o impacto que a violência política exerceu

Para dicho análisis, se propone un modelo del mercado de gas natural en Colombia, el cual incluye la oferta, la demanda, y las restricciones de transporte, así como las importaciones y exportaciones. El modelo se basa en la representación del comportamiento de los productores y su efecto en el mercado. Ya en este mercado la oferta es un oligopolio y el modelo es un modelo de equilibrio espacial con competencia a la Cournot. Los fl ujos resultantes del modelo indican que el impacto inicial de las exportaciones a Venezuela sobre el mercado Colombiano es bajo, y que las importaciones desde Venezuela mejoran la seguridad del suministro de gas al mercado y aumentan la competencia entre los productores.

    The emerging vector of Chagas disease, Triatoma maculata (Hemiptera, Reduviidae), is one of the most widely distributed Triatoma species in northern South America. Despite its increasing relevance as a vector, no consistent picture of the magnitude of genetic and phenetic diversity has yet been developed. Here, several populations of T. maculata from eleven Colombia and Venezuela localities were analyzed based on the morphometry of wings and the mitochondrial NADH dehydrogenase subunit 4 (ND4) gene sequences. Our results showed clear morphometric and genetic differences among Colombian and Venezuelan populations, indicating high intraspecific diversity. Inter-population divergence is suggested related to East Cordillera in Colombia. Analyses of other populations from Colombia, Venezuela, and Brazil from distinct eco-geographic regions are still needed to understand its systematics and phylogeography as well as its actual role as a vector of Chagas disease.

    An 83-year-old male patient is admitted to the central hospital in Cumana, Venezuela with severe urinary infection, history of hospitalizaions and prolonged antimicrobial treatments. A strain of Enterobacter cloacae was isolated showing resistance to multiple types of antibiotics (only sensitive to gentamicin), with phenotype of serine- and metallo-carbapenemases. Both, bla(VIM-2) and bla(KPC) genes were detected in the isolate. This is the first report of an Enterobacteriaceae species producing both KPC carbapenemase and VIM metallo carbapenemase in Venezuela. This finding has a great clinical and epidemiological impact in the region, because of the feasibility of transferring these genes, through mobile elements to other strains of Enterobacter and to other infection-causing species of bacteria.

  4. Suboxic dolomite formation linked to the sedimentary Mn cycle, Archipelago Los Roques, Venezuela

    The preferential formation of Ca-rich dolomite precursors in modern peritidal environments has been associated with the degradation of buried microbial mats, with complexation of Ca and Mg cations by extracellular polysaccharides, and alkalinity generation, mostly through bacterial sulfate reduction. However, it remains unclear why Ca-dolomite would not occur in suboxic sediments where bacterial Mn(IV) and/or Fe(III) reduction are important sources of alkalinity, and the role, if any, of Fe- and Mn-recycling in its diagenetic stabilization to more stoichiometric dolomite is unknown. In a shoaling-upward parasequence in the Archipelago Los Roques, Venezuela, an abundance of Ca-dolomite coincides with a relative decrease in bulk-sediment iron concentrations. These sediments were analyzed with multiple analytical tools, including EPMA, ICP-MS, synchrotron-based XRF, XRD, and spatially resolved XANES. Results demonstrate that the distribution of spheroidal aggregates of nanometer-scale Ca-rich dolomite rhombohedra is linked with interstitial elemental sulfur and manganese accumulations, with Mn occurring in several oxidation states (Fig. 1). Based on our observations at this novel dolomite-forming site, we suggest that in peritidal settings the burial of metal-reactive microbial mats act as a barrier capable of concentrating dissolved reactive species that promote greater sediment residence times in suboxic (manganic) zones, where the recycling of Mn not only plays an important role in the remineralization of organic matter, but also sustains elevated alkalinity and dissolved pore water sulfide concentrations. The last two effects have been previously suggested to promote Mg dehydration, the major kinetic barrier to dolomite nucleation. Figure 1. Normalized Mn K-edge merged spectra of a 5 x 5 μm analytical area bearing dolomite cements. A: The K-edge exhibits two main features at about 6554 and 6558 eV.

    We studied the wood anatomy of 29 species belonging to 10 genera of the tribe Detarieae, subfamily Caesalpinioideae and compare them with tribe Caesalpinieae. Detarieae is the largest of four tribes of Caesalpinioideae, with 84 genera, only eleven occur in Venezuela with species of timber importance. The specimens were collected in Venezuela and include wood samples from the collection of the Laboratorio de Anatomía de Maderas de la Facultad de Ciencias Forestales y Ambientales de la Universidad de Los Andes, Venezuela, and of the Forest Products Laboratory of the USDA Forest Service in Madison, Wisconsin, USA. The terminology and methodology used followed the IAWA List of Microscopic Features for Hardwood Identification of the IAWA Committee, 1989. Measurements from each specimen were averaged (vessel diameters, vessel element lengths, intervessels pit size, fibre lengths and ray height). The species of Detarieae can be separated using a combination of diagnostic features. Wood characters that provide the most important diagnosis and may be used in systematics of Detarieae include: intercellular axial canals, rays heterocellular, rays exclusively or predominantly uniseriate, prismatic crystals common in ray cells, irregular storied structure and fibre wall thickness. For comparative anatomy between Detarieae and Caesalpinieae: intercellular axial canals, heterocellular rays, rays exclusively or predominantly uniseriate, prismatic crystals common in ray cells (in Detarieae) and regular storied structure, fibres septate, fibre wall thick or very thick, rays homocellular, multiseriate rays and silica bodies (in Caesalpinieae). Axial parenchyma is typically a good diagnostic feature for Leguminosae, but not for Detarieae and Caesalpinieae comparisons.

    In the last few years the paleomagnetism research group, at the Universidad Simon Bolivar in Caracas (Venezuela), has undertaken combined studies of rock magnetism (e.g. natural magnetic remanence, magnetic susceptibility, hysteresis parameters etc.) and dielectric properties (maximum current depolarization temperatures and average activation energies) in Cretaceous and Paleogene sedimentary sequences from eastern and western Venezuela. Our main goal has been to find new ways of defining physical markers, in fossil- poor sedimentary rocks, for stratigraphic correlations. Magneto/dielectric characterizations of these rocks have proved also useful identifying lithological discontinuities and paleoenvironmental changes. More recently these two-fold technique have been extended to archeological materials (potsherds) from a series of Venezuelan islands, in order to track down clay sources and find out about different stages of pottery craftsmanship. Magneto/Dielectric characterization of archeological potsherds seems to allow the tracing of their provenance from various mainland prehistoric settlements of distinct Venezuelan amerindian groups. In this paper we present a comprehensive review of this research applied to a contact between two sedimentary formations in eastern Venezuela (Cretaceous Chimana/Querecual) and a number of pottery samples with diverse stylistic features excavated in a single archeological site from Los Roques islands.

    2002-01-01

    The judicial regulation of genetic biotechnology applied to the human genome is of big relevance currently in Venezuela due to the drafting of an innovative bioethical law in the country's parliament. This article will highlight the constitutional normative of Venezuela's 1999 Constitution regarding this subject, as it establishes the framework from which this matter will be legally regulated. The approach this article makes towards the genetic biotechnology applied to the human genome is made taking into account the Venezuelan penal law and by highlighting the violent genetic manipulations that have criminal relevance. The genetic biotechnology applied to the human genome has another important relevance as a consequence of the reformulation of the Venezuelan Penal Code discussed by the country's National Assembly. Therefore, a concise study of the country's penal code will be made in this article to better understand what judicial-penal properties have been protected by the Venezuelan penal legislation. This last step will enable us to identify the penal tools Venezuela counts on to face direct genetic manipulations. We will equally indicate the existing punitive loophole and that should be covered by the penal legislator. In conclusion, this essay concerns criminal policy, referred to the direct genetic manipulations on the human genome that haven't been typified in Venezuelan law, thus discovering a genetic biotechnology paradise.

  4. Could the Chagas disease elimination programme in Venezuela be compromised by reinvasion of houses by sylvatic Rhodnius prolixus bug populations?

    2006-10-01

    The Andean Pact Initiative (1997) committed Andean countries to eliminate vectorial transmission of Chagas disease by 2010 via widespread residual insecticide spraying. In Venezuela, this aim could be compromised by reinvasion of houses by palm tree populations of the major vector Rhodnius prolixus. To test this hypothesis, a multivariate logistic regression was undertaken of risk factors for triatomine infestation and colonization in 552 houses and 1068 peri-domestic outbuildings in Barinas State. After adjusting for other risk factors, including palm roofs, R. prolixus infestation and colonization of outbuildings (and, to some extent, houses) was significantly associated with proximity to high densities of Attalea butyracea palm trees. House infestation and/or colonization was also positively associated with bug density in peri-domestic outbuildings, the presence of pigsties and nests. Hence, R. prolixus populations in ineffectively sprayed outbuildings could also provide an important source of house re-infestations. The secondary vector Triatoma maculata was mainly found associated with the presence of hens nesting both indoors and outdoors.

    Between may and july 2001, a survey was conducted in order to investigate the prevalence and symptoms of Enterobius vermicularis infection and its relationship with the socio-economic status and household crowding of 154 schoolchildren aged 6-12 years from a rural village in Falcon State, Venezuela. The Graham technique (perianal swabs with an adhesive cellulose tape) was used to perform the parasitological diagnosis. The overall prevalence was high (57.79%). There was no difference in the prevalence between sexes (X2 = 0.005; d.f. = 1) or ages (X2 = 3.63; d.f. = 6) (p > 0.05), suggesting similar risk conditions for all individuals. Anal pruritus was the most common clinical finding (53.9%). Other less frequent manifestations were the following: perianal lesions (34.8%) and vulvovaginitis (32.6%). Graffar analysis revealed that the majority of schoolchildren belong to the poorer socioeconomic strata: IV (55.9%) and V (29.87%), with overcrowded living conditions. The correlation between E. vermicularis infection and crowding rates was found to be statistically significant (r = 0.98; p enterobiasis among schoolchildren from Sabaneta.

Micropogonias furnieri has a small ventral mouth; protrusible premaxillary and dentary; first branchial arches with 21 to 27 gill rakers, generally 24 to 25; and 7 to 11 pyloric caecae. The index of vacuity was low, with mean value of 7.00%. The mean intestinal index was 0.72, indicative of carnivorous species. Analysis of frequency of occurrence, indicates preference for crustaceans (45.70%), mainly crabs (34.90%), followed by polychaetes (28.00%), fishes (11.41%) and occasionally mollusks and echinoderms (4.0 and 3.9%, respectively). The diet of this species did not vary with sex.

    The results from Annex XIII of the Cooperative Agreement between the United States Department of Energy (DOE) and the Ministry of Energy and Mines of the Republic of Venezuela (MEMV) have been documented and published with many researchers involved. Integrate comprehensive research programs in the area of Microbial Enhanced Oil Recovery (MEOR) ranged from feasibility laboratory studies to full-scale multi-well field pilots. The objective, to cooperate in a technical exchange of ideas and information was fully met throughout the life of the Annex. Information has been exchanged between the two countries through published reports and technical meetings between experts in both country's research communities. The meetings occurred every two years in locations coincident with the International MEOR conferences & workshops sponsored by DOE (June 1990, University of Oklahoma, September 1992, Brookhaven, September 1995, National Institute of Petroleum and Energy Research). Reports and publications produced during these years are listed in Appendix B. Several Annex managers have guided the exchange through the years. They included Luis Vierma, Jose Luis Zirritt, representing MEMV and E. B. Nuckols, Edith Allison, and Rhonda Lindsey, representing the U.S. DOE. Funding for this area of research remained steady for a few years but decreased in recent years. Because both countries have reduced research programs in this area, future exchanges on this topic will occur through ANNEX XV. Informal networks established between researchers through the years should continue to function between individuals in the two countries.

    The aim of this work was to carry out a geochemical study of channel samples collected from six coal beds in the Marcelina Formation (Zulia State, western Venezuela) and to determine experimentally the gas content of the coals from the Paso Diablo mine. Organic geochemical analyses by gas chromatography-mass spectrometry and isotopic analyses on-line in coalbed gas samples were performed. The results suggest that the Guasare coals were deposited in a continental environment under highly dysoxic and low salinity conditions. The non-detection of 18??(H)-oleanane does not preclude that the organic facies that gave rise to the coals were dominated by angiosperms. In addition, the presence of the sesquiterpenoid cadalene may indicate the subordinate contribution of gymnosperms (conifers) in the Paleocene Guasare mire. The average coalbed gas content obtained was 0.6 cm3/g. ??13C and D values indicate that thermogenic gas is prevalent in the studied coals. Copyright ?? Taylor & Francis Group, LLC.

  13. The Resource Relationship: The Institutional Legacies of Oil in Venezuela

    Science.gov (United States)

    Bridgewater, Elliot

    This thesis problematizes the concept of the 'Resource Curse', addressing the arguments of several theorists that resource dependence results in state monopolization of natural resource production, and causes poor development outcomes in resource dependent states. A single case study of the Venezuelan experience is used in order to take a longer-run historical approach that considers economic and political determinants of oil-dependent development starting with the impressive growth and emerging democracy of the post war period, economic stagnation of the 1980's and 1990's, and the divisive contemporary era of 'Chavismo'. To deconstruct the thesis that oil and development do not mix, each chapter explores the dynamic connections between the fiscal structure of the Venezuelan state, institutionalized patterns of political conflict and compromise, and their socio-economic consequences. It is argued that such a multi-faceted approach moves beyond static interpretations of the resource curse to grasp more firmly the ever-changing resource relationship.

    Candida species other than C. albicans are often described as causative agents of superficial mycosis and are more resistant to treatment with azoles. In order to determine the distribution of species and in vitro antifungal susceptibility of Candida spp., one ambispective study, which analyzed 18 yeast isolates obtained from samples from patients diagnosed with superficial mycosis, was performed. Taxonomic identification was performed by macroscopic visualization of the growth characteristics in chromogenic agar and by conventional methods. The susceptibility to fluconazole and voriconazole was evaluated by the disc diffusion method. Most of the isolates (88.8%), came from nail samples. C. parapsilosis was the most common species, followed by C. tropicalis, C. albicans and C. krusei, which confirmed the prevalence of non-albicans species as a cause of superficial mycoses. The pattern of susceptibility to fluconazole and voriconazole was similar: all isolates of C. parapsilosis and C. albicans were susceptible, while 83.3% of C. tropicalis showed sensitivity to both antifungals. C. krusei, fluconazole-resistant species showed intermediate susceptibility io voriconazole. The use of chromogenic agar allowed to detect mixed infections in nail samples, involving Candida spp. and C. tropicalis in one case, the latter with resistance to both fluconazole and voriconazole. The results demonstrate the importance of species identification and susceptibility testing to avoid therapeutic failures in superficial mycoses.

Civil protests of 2014 brought into evidence the dissolution of borders, increasingly blurred, between traditional mass media and digital platforms which are enabling direct user access to the media sphere. In this article, we provide and analyze examples and also, theoretical elements contributing to an interpretation of the phenomenon. The government's information blockade is the axis that has forced communities to form new social info-network where to build stories and models of reading on critical environment and its phases of tension.

  3. Residential energy use and conservation in Venezuela: Results and implications of a household survey in Caracas

    Figueroa, M.J.; Ketoff, A.; Masera, O.

    1992-10-01

    This document presents the final report of a study of residential energy use in Caracas, the capital of Venezuela. It contains the findings of a household energy-use survey held in Caracas in 1988 and examines options for introducing energy conservation measures in the Venezuelan residential sector. Oil exports form the backbone of the Venezuelan economy. Improving energy efficiency in Venezuela will help free domestic oil resources that can be sold to the rest of the world. Energy conservation will also contribute to a faster recovery of the economy by reducing the need for major investments in new energy facilities, allowing the Venezuelan government to direct its financial investments towards other areas of development. Local environmental benefits will constitute an important additional by-product of implementing energy-efficiency policies in Venezuela. Caracas`s residential sector shows great potential for energy conservation. The sector is characterized by high saturation levels of major appliances, inefficiency of appliances available in the market, and by careless patterns of energy use. Household energy use per capita average 6.5 GJ/per year which is higher than most cities in developing countries; most of this energy is used for cooking. Electricity accounts for 41% of all energy use, while LPG and natural gas constitute the remainder. Specific options for inducing energy conservation and energy efficiency in Caracas`s residential sector include energy-pricing policies, fuel switching, particularly from electricity to gas, improving the energy performance of new appliances and customer information. To ensure the accomplishment of an energy-efficiency strategy, a concerted effort by energy users, manufacturers, utility companies, government agencies, and research institutions will be needed.

    Full Text Available RESUMEN: El análisis de la distribución y redistribución del ingreso en Venezuela se puede resumir en tres conclusiones generales. En primer lugar, la distribución del ingreso en Venezuela es más desigual en el año 2000 que a finales de la década de 1970. En segundo lugar, esta situación se debe a un descenso en la acumulación de capital que está también asociado al colapso del producto y el ingreso. En tercer lugar, el descenso en la acumulación de capital no parece estar asociado a la desigualdad inicial de la economía o a mecanismos redistributivos por parte del gobierno. Puede decirse que la contracción del crecimiento económico es lo que ha causado el aumento de la pobreza y el aumento de la desigualdad en la economía venezolana.ABSTRACT: An analysis of distribution and redistribution of income in Venezuela leads to three general conclusions. In first place, the distribution of income is more unequal in 2000 than by the end of the seventies. In second place, this situation is due to a drop in the accumulation of capital, also linked to the collapse of the product and the income. In third place, the drop in the accumulation of capital does not seem to be associated to the initial inequality of the economy or to redistributive mechanisms of the government. It is possible to say that the reduction of the economic growth has caused an increase of the poverty and the raise of inequality in the Venezuelan economy.

Este artículo presenta un análisis sobre la actuación de las ciencias sociales durante el siglo 20 en el campo de la medicina y la salud, en Venezuela. Se establecieron variables relacionadas con los cambios y/o transformaciones que se han dado en la sociedad, el Estado y la academia, las cuales permitieron construir cinco fases que denotan los estilos y formas de concebir la relación entre las ciencias sociales y la salud: a lo social como un asunto de descubrimiento médico; b lo social y lo sanitario como apoyo a la modernización; c la profesionalización de lo social: de la medicina social a las ciencias sociales; d lo social como crítica al poder; e la diversidad de lo social: de la medicina a la salud. La actuación crítica y constructiva de las ciencias sociales en el campo de la medicina y la salud, su contribución en los programas y acciones en salud desarrolladas por el Estado y, en el área de la investigación, le han otorgado el reconocimiento como claves en los cambios sociales necesarios para la modernización, hasta ahora inconclusa, de la sociedad venezolana.The social sciences have been involved in health programs in Venezuela since the turn of the 20th Century, but their role has been changing as the country has undergone successive transformations and the scientific community has matured.

    Background Limited information exists on the epidemiology of acute febrile respiratory illnesses in tropical South American countries such as Venezuela. The objective of the present study was to examine the epidemiology of influenza-like illness (ILI) in two hospitals in Maracay, Venezuela. Methodology/Principal Findings We performed a prospective surveillance study of persons with ILI who presented for care at two hospitals in Maracay, Venezuela, from October 2006 to December 2010. A respiratory specimen and clinical information were obtained from each participant. Viral isolation and identification with immunofluorescent antibodies and molecular methods were employed to detect respiratory viruses such as adenovirus, influenza A and B, parainfluenza, and respiratory sincytial virus, among others. There were 916 participants in the study (median age: 17 years; range: 1 month – 86 years). Viruses were identified in 143 (15.6%) subjects, and one participant was found to have a co-infection with more than one virus. Influenza viruses, including pandemic H1N1 2009, were the most frequently detected pathogens, accounting for 67.4% (97/144) of the viruses detected. Adenovirus (15/144), parainfluenza virus (13/144), and respiratory syncytial virus (11/144) were also important causes of ILI in this study. Pandemic H1N1 2009 virus became the most commonly isolated influenza virus during its initial appearance in 2009. Two waves of the pandemic were observed: the first which peaked in August 2009 and the second - higher than the preceding - that peaked in October 2009. In 2010, influenza A/H3N2 re-emerged as the most predominant respiratory virus detected. Conclusions/Significance Influenza viruses were the most commonly detected viral organisms among patients with acute febrile respiratory illnesses presenting at two hospitals in Maracay, Venezuela. Pandemic H1N1 2009 influenza virus did not completely replace other circulating influenza viruses during its initial

También se hace prioritaria la búsqueda de la integración regional tanto a nivel público como privado a través de instituciones como Mercosur y la Comunidad Andina de Naciones.Este artículo plantea las incidencias de la globalización y la integración en la política exterior venezolana y los mecanismos a aplicar para ajustarse al nuevo modelo mundial. Tres son los puntos prioritarios en este sentido: los cambios globales, el petróleo y la política exterior.La situación de Venezuela como país proveedor de petróleo a Estados Unidos le ha permitido ser conservador en sus posiciones y asumir la apertura económica de forma más discreta al resto de países de la región. La democracia es otro tema que rodea las relaciones internacionales, especialmente lo relativo a los derechos humanos y al buen gobierno, y del cual Venezuela se beneficia al procurar un espacio idóneo para su desarrollo.ABSTRACT: The world has moved towards globalization, which means that Latin America, that has low international leverage and a critical economic situation, has to search for an adjustment to the new international demands by means of "deregulation and economic coordination".

    The distribution of mansonelliases and their relation to various quantitative criteria were determined through the study of 1,057 subjects in 17 localities in ten regions of Amazonas State and Bolívar State. The total prevalence among the blood samples, determined through the Knott technique, was 18.54%. 11.26% were parasited by Mansonella perstans, 9.93% by Mansonella ozzardi, and 2.63% by both species. The average of microfilaremia was 48.19 mf/mL of blood in M. perstans and 13.79 mf/mL in M. ozzardi. In the regions studied, M. ozzardi has a wider area of distribution than M. perstans. Prevalence, average number of parasites per host, and the infection index have a positive and statistically significant correlation with the total annual precipitation mean for each region for M. perstans; in the case of M. ozzardi the quantitative parameters are positively correlated with the altitude of each region, this correlation being statistically significant. With respect to type of vegetation, M. perstans had a higher infection index in Amazonian caatinga transition in pluvial lowland forest, and M. ozzardi in semideciduous forest of the alisio type. Therefore two types of transmission, M. ozzardi-Simulium and M. perstans-Culicoides are suggested.

    Full Text Available The effect of contamination with mercury (Hg in the deep subsurface bacterial communities in the region of El Callao (Bolívar State, Venezuela was investigated. Bacterial communities from two deep levels (-288 m and -388 m in a gold mine were studied with the aim of describe the most relevant features of their colonizing indigenous culturable bacteria. Antibiotic and heavy metals resistance patterns, presence of the merA gene and plasmids in resistant isolates were evaluated. A high frequency of resistant indigenous bacteria to Hg and other heavy metals was found. From 76 Hg-resistant isolates tested 73.7 % were, in addition, resistant to ampicillin, 86.8% to chloramphenicol, 67.1 % for tetracycline, 56.6 % streptomycin, and 51.3 % kanamycin. Furthermore, it was found that 40.74 % (-328 mm and 26.53 % (-388 m of Hg-resistant bacteria were simultaneously resistant to both four and five of these antibiotics. The presence of low and high molecular weight plasmids was detected and, despite that isolated showed resistance to mercurial compounds, the presence of the gene merA was detected only in 71.05 % of strains. These results suggest that exposure to Hg could be a selective pressure on the proliferation of antibiotic-resistant bacteria and promote the preservation and propagation of these resistance genes. However, the existence of such resistances to these depths could also support the idea that antibiotic resistance in these bacteria is natural and has a more ancient origin than their exposure to Hg.

    87Sr/86Sr ratios, δ13C, and δ18O determinations performed on 30 bulk carbonate rocks are presented to constrain the isotope characteristics regarding Oceanic Anoxic Event 3 in the La Luna Formation, Maracaibo Basin. The samples were collected along a 22 m profile in San Miguel region (Merida State, Venezuela). The exhibited 87Sr/86Sr ratios are between 0.707659, at the base, and 0.707733 at the top of studied section, corresponding estimated younger numerical ages than the inferred ages dated as Santonian (85.8-83.5 Ma) based on occurrence of Dicarinella asymetrica. The obtained 87Sr/86Sr ratios are certainly higher than expected for Santonian sea Sr and they are attributed to regular riverine strontium fluxes in the restricted (gulf-like) Maracaibo Basin. The values of δ18O data between -3.76‰ and -11.76‰ are distributed in two distinct clusters in a same way and coherent as for δ13C data which are in a range between -1.75‰ and -13.87‰. One of the clusters δ13C = -2.5 ± 1.0‰ and δ18O = -10.0 ± 1.5‰), illustrate the homogeneous marine deposition under tropical conditions, while the other, more variable, probably could reflect the cyclicity of temporally changes in Pacific versus Atlantic Ocean circulation with cooling water or cooling trend climate. These δ13C values around -2.5 ± 1.0‰ do not fit with the significant carbon isotope excursion as expected for the oceanic anoxic event (OAE) and support the work hypothesis that Coniacian-Santonian anoxic event (denominate as OAE3) is not a global one.

  18. Revised seismic history of the El Pilar fault, Northeastern Venezuela, from the Cariaco 1997 earthquake and recent preliminary paleoseismic results

    2007-07-01

    In light of the July 9, 1997, Cariaco earthquake, it is clearly understood now that damage in the city of Cumaná located in northeastern Venezuela and frequently destroyed by the largest earthquakes since the first recorded event in 1530 is strongly enhanced by poor soil conditions that, in turn, are responsible for site amplification and widespread earthquake-induced effects. Therefore, most previous macroseismic studies of historical earthquakes must be revaluated because those localized high-intensity values at Cumaná surely led to the misestimation of past epicenters. Preliminary paleoseismic results, gathered at three exploratory trenches dug across the surface break of the Cariaco 1997 earthquake in 1998, allow us to associate the 1684 earthquake with this recently ruptured fault segment that extends between the towns of San Antonio del Golfo and Río Casanay (roughly between the two gulfs of Cariaco and Paria, state of Sucre). Other major results from the reassessment of the seismic history of this fault are: (a) the 1766 event seems to have generated in a different source to the El Pilar fault because the size of the felt area suggests that it is an intermediate-depth earthquake; (b) damage to Cumaná produced by the 1797 event suggests that this was a local earthquake, perhaps equivalent to the 1929 earthquake, which ruptured for some 30 km just east of Cumaná into the Gulf of Cariaco; and (c) seismogenic association of the 1530 and 1853 earthquakes still remains unclear but it is very likely that these ruptures occurred offshore, as suggested by the rather large tsunami waves that both events have generated, placing their hypocenters west of Cumaná in the Cariaco Trough. This reassessment also sheds light into the El Pilar fault segmentation and the behavior of its seismogenic barriers through time.

    Full Text Available En el presente artículo se plantea el negocio de franquicia como una alternativa viable para canalizar la problemática de la informalidad laboral en Venezuela. Con base a un análisis documental-bibliográfico, semuestra la aplicabilidad de dichomodelo en un proceso de reconversión de la actividad económica informal en el país. Para lograrlo, se ha considerado la articulación entre diferentes conceptos económicos: el modelo de franquicia de conversión y la problemática de la economía informal en Venezuela, flagelo económico social presente en la realidad venezolana. Se concluye que un modelo de reconversión de la actividad económica informal representaría una alternativa para transformar esta actividad en el país, planteándose la conformación de una PYME con fortalezas financiera y operacional, con altos niveles de racionalidad, cuya actividad principal es ejecutada por otros individuos de manera informal; de esta forma se estructura una estrategia de crecimiento en función de la absorción de los ejecutores informales quienes, a través del financiamiento público o privado, concretan la conformación de una microempresa y la firma de un contrato tipo franquicia con la PYME.

Esas funciones estuvieron sometidas a diversos marcos de actuación jurídico-legal, especialmente durante el periodo republicano y hasta su extinción en 1870, mediante los decretos emitidos por el presidente Antonio Guzmán Blanco. Así, se examina el funcionamiento y las regulaciones a que estuvo sometido el sistema financiero eclesiástico en Venezuela, y las tensiones que enfrentaron al clero con los gobiernos decimonónicos. El estudio parte de la revisión bibliográfica y documental sobre la temática, en particular de las fuentes manuscritas que reposan en los archivos regionales, nacionales y extranjeros. La investigación demuestra la intensa participación del sector rentista religioso en la protección de sus capitales e intereses y su progresiva decadencia durante el siglo XIX, debido a la incapacidad para obtener nuevos aportes de numerario, recapitalizar intereses, reaccionar ante la competencia de capital foráneo y protegerse de la apetencia de poderosos e importantes grupos políticos que buscaban apropiarse de sus caudales.

A total of 175 serum samples were collected in the community of Piñantal during February 2009. Interviews targeting socioeconomic and environmental factors associated with the T. cruzi transmission were also conducted. Samples were evaluated using trypomastigote excreted/secreted antigens (TESAs in an ELISA format. TESA-ELISA positive samples were confirmed by indirect haemagglutination (HAI (Wiener. A nonsystematic collection of vectors was also undertaken. T. cruzi seroprevalence was 7.43% according to both assays, and the mean age of infected patients was 48.61±10.40 years (range 34 to 73 years. The vector infection rate was 20.00% (2/10. T. cruzi seropositivity was associated with a history of triatomine bites, the ability to recognize the vector and poor knowledge about Chagas disease, but no associations were found with gender, house type, knowledge of how the disease is transmitted, or the presence of vectors or animals inside dwellings. To our knowledge, this is the first study of the seroprevalence of T. cruzi in an indigenous population in eastern Venezuela. All of the epidemiological variables required for the establishment of active vectorial transmission of T. cruzi were present in this community.

    2016-03-01

    Dominantly inherited ataxias (spinocerebellar ataxias, SCAs) are a genetically heterogeneous group of neurologic diseases characterized by progressive cerebellar and spinal tract degeneration with ataxia and other signs, common to all known subtypes. Several types are relatively frequent worldwide, but in several countries, one specific SCA may show a higher prevalence owing to founder phenomena. In Venezuela, genetic epidemiological features of SCAs have been assessed during the last 30 years; mutations in ATXN1 (SCA1), ATXN2 (SCA2), ATXN3 (SCA3), CACNA1A (SCA6), ATXN7 (SCA7), ATXN8 (SCA8), ATXN10 (SCA10), TBP (SCA17) and ATN1 (dentatorubral pallidoluysian atrophy, DRPLA) loci were searched among 115 independent families. SCA7 was the most frequent subtype (26.6%), followed by SCA3 (25.0%), SCA2 (21.9%), SCA1 (17.2%), SCA10 (4.7%) and DRPLA (3.1%); in 43% of the families, the subtype remained unidentified. SCA7 mutations displayed strong geographic aggregation in two independent founder foci, and SCA1 showed a very remote founder effect for a subset of families. SCA10 families were scattered across the country, but all had an identical in-phase haplotype carried also by Mexican, Brazilian and Sioux patients, supporting a very old common Amerindian origin. Prevalence for dominant SCAs in Venezuela was estimated as 1:25 000 nuclear families, provenances of which are either Caucasoid, African or Amerindian.

    During a survey in western Venezuela in 2011, three new populations of Heterorhabditis amazonensis (LPV081, LPV156, and LPV498) were isolated. Some differences were found in terms of morphometry compared with the original description; however, the distance from the anterior end to the excretory pore is the most variable character; significantly shorter in all infective juveniles and in other developmental stages depending on the population. According to a Principal Component Analysis, LPV498 possesses more differences in morphometric characteristics and can be separated from the other two. Those intraspecific differences could be attributed to the geographic origin of the nematode. Molecular studies of ITS regions demonstrated that the sequences of the Venezuelan strains were identical to those of the type species originally isolated in the Brazilian Amazonian forest. This is an interesting fact because in several studies on heterorhabditids, intraspecific variability has been recorded. Herein, we present the first report of H. amazonensis in Venezuela and the characterization of three populations of this species.

Estas reformas reforzaron la influencia congresista de la patronal y los sindicatos, en vez de ampliar los patrones de representación para incluir las preocupaciones de los intereses emergentes.El fracaso de las reformas moderadas para mejorar la representación favoreció a candidaturas de políticas que apoyaron las agendas políticas radicales, como la de Hugo Chávez.ABSTRACT: This article examines representation in the 1994-1999 Venezuelan Chamber of Deputies to contextualize the presidencial candidacy of Hugo Chávez. In 1993, the Venezuelan the two-party system broke down and a new mixedmember electoral law for Congress was implemented. These reforms reinforced the congressional influence of business and labor rather than broaden representation patterns to include the concerns of emerging interests. The failure of moderate reforms to improve representation created conditions that favored the candidacies of politicians, like Hugo Chávez, who endorsed radical political agendas.

    In general, it has been reported that rotavirus infection was detected year round in tropical countries. However, studies in Venezuela and Brazil suggest a seasonal behavior of the infection. On the other hand, some studies link infection with climatic variables such as rainfall. This study analyzes the pattern of behavior of the rotavirus infection in Carabobo-Venezuela (2001-2005), associates the seasonality of the infection with rainfall, and according to the seasonal pattern, estimates the age of greatest risk for infection. The analysis of the rotavirus temporal series and accumulated precipitation was performed with the software SPSS. The infection showed two periods: high incidence (November-April) and low incidence (May-October). Accumulated precipitation presents an opposite behavior. The highest frequency of events (73.8% 573/779) for those born in the period with a low incidence of the virus was recorded at an earlier age (mean age 6.5 +/- 2.0 months) when compared with those born in the station of high incidence (63.5% 568/870, mean age 11.7 +/- 2.2 months). Seasonality of the infection and the inverse relationship between virus incidence and rainfall was demonstrated. In addition, it was found that the period of birth determines the age and risk of infection. This information generated during the preaccine period will be helpful to measure the impact of the vaccine against the rotavirus.

    Hepatitis A virus (HAV) infection is highly prevalent in Latin America, including Venezuela. Subgenotype IA seems to circulate in an almost exclusive fashion, except in Brazil. The aim of this study was the molecular characterization of the HAV infection in Venezuela, in order to characterize the circulating strains and to analyze the presence of quasispecies in sporadic cases and an epidemic outbreak. A total of 125 (113 sera and 12 feces) samples positive for anti-HAV IgM from sporadic cases and epidemic outbreak, were submitted to hemi-nested RT-PCR for amplification of the VP1 N terminus or complete region of the HAV genome. Sequences obtained from 96 Venezuelan isolates were used for phylogenetic analysis. The quasispecies distribution was evaluated by cloning of HAV amplicons. Phylogenetic analysis of HAV sequences from Venezuela showed the exclusive circulation of subgenotype IA, but with co-circulation of two lineages, not found in other countries. The genetic variability found among Venezuelan strains was also analyzed by single-strand conformation polymorphism (SSCP). This technique allowed the detection of intra-strain variability, which was indeed related to the presence of quasispecies populations in the isolates. The quasispecies heterogeneity was higher in some isolates derived from sporadic cases compared to the one observed in the outbreak. The molecular characterization of HAV isolates from Venezuela showed the circulation of a unique subgenotype IA, but with the presence of diverse strains and quasispecies inside the viral populations.

    Full Text Available Toxoplasmosis and neosporosis have been recognized as economically important diseases with considerable impact on the livestock industry. Little is known concerning the occurrence of Toxoplasma gondii and Neospora caninum in sheep from Tocantins state, Brazil. Here, we investigated antibodies against these parasites and associated factors in 182 sheep from Araguaína, Santa Terezinha do Tocantins, Arguianópolis and Palmeiras do Tocantins districts, Tocantins. Sheep sera were assayed for T. gondii and N. caninum IgG antibodies by indirect fluorescence antibody test (IFAT, using cut-off point at a dilution of 1:40 and 1:25 respectively. The prevalence of seropositive animal for T. gondii was 13.74% and 13.74% for N. caninum. None of the characteristics studied including reproductive problems, presence of cats, presence of dogs and veterinary care (p>0.05 was associated with occurrence of T. gondii or N. caninum infection. Only breed was identified as associated factor for the occurrence of toxoplasmosis in sheep (p<0.05. The present study is the first report on serum occurrence of T. gondii and N. caninum in sheep from the state of Tocantins, Brazil.

    Full Text Available During the administration of Hugo Chavez, social expenditure in Venezuela expanded in relative and absolute terms simultaneously with the increase in oil revenues. Expenditures even went beyond the levels reached during the previous oil boom in the 1970s, particularly due to the expenditures in social security. Based on an analysis of Venezuela's social and economic structure, we show that this increase is aimed mostly towards the working population that is increasingly seen as excess workers. The increase in expenditure substantially improves the living conditions of this group. However, since there is no change in capital accumulation in Venezuela, this group continues to consolidate itself as excess wokers.

    ABSTRACT

    Mitocondrial DNA (mtDNA has been widely used to study genetic relationships between contemporary Amerindian groups and to infer ancestral migration movements; however inferences about migration routes of prehispanic extinct groups are difficult. Admixture of Neoamerican groups has been characterized by unions between European males and Amerindian females. This allows the identification in present populations of Amerindian mitocondrial haplogroups which give information on ancestral groups. In order to investigate female lineages present in western Venezuela, RFLP haplogroups from mtDNA were obtained from 193 individuals with grandparents from this region, 81 from the State of Lara (Barquisimeto and 112 from 3 towns of the State of Falcon (Macuquita=25; Macanilla=29 and Churuguara=58. Comparison of haplogroup distributions between groups was performed, and admixture estimates based on female lineages were obtained. The distribution of four Amerindian haplogroups was compared with those of other populations from the American Continent. In our four samples Amerindian haplogroups predominate, followed by those of African origin. In the comparison of the mtDNA Amerindian fraction with other populations we find that Macanillas, Lara and Churuguara are similar to South American and Amazonian groups whilst Macuquita is similar to groups from Aruba. Our findings suggest an important genetic diversity in this region, explained by migration routes to and from the south and the Caribean. They also suggest genetic relationship between prehispanic groups from Aruba and those from the Paraguaná peninsula, which have been inferred by

  1. The Production and Utilization of GDP-glucose in the Biosynthesis of Trehalose 6-Phosphate by Streptomyces venezuelae*

    Trehalose-6-phosphate synthase OtsA from streptomycetes is unusual in that it uses GDP-glucose as the donor substrate rather than the more commonly used UDP-glucose. We now confirm that OtsA from Streptomyces venezuelae has such a preference for GDP-glucose and can utilize ADP-glucose to some extent too. A crystal structure of the enzyme shows that it shares twin Rossmann-like domains with the UDP-glucose-specific OtsA from Escherichia coli. However, it is structurally more similar to Streptomyces hygroscopicus VldE, a GDP-valienol-dependent pseudoglycosyltransferase enzyme. Comparison of the donor binding sites reveals that the amino acids associated with the binding of diphosphoribose are almost all identical in these three enzymes. By contrast, the amino acids associated with binding guanine in VldE (Asn, Thr, and Val) are similar in S. venezuelae OtsA (Asp, Ser, and Phe, respectively) but not conserved in E. coli OtsA (His, Leu, and Asp, respectively), providing a rationale for the purine base specificity of S. venezuelae OtsA. To establish which donor is used in vivo, we generated an otsA null mutant in S. venezuelae. The mutant had a cell density-dependent growth phenotype and accumulated galactose 1-phosphate, glucose 1-phosphate, and GDP-glucose when grown on galactose. To determine how the GDP-glucose is generated, we characterized three candidate GDP-glucose pyrophosphorylases. SVEN_3027 is a UDP-glucose pyrophosphorylase, SVEN_3972 is an unusual ITP-mannose pyrophosphorylase, and SVEN_2781 is a pyrophosphorylase that is capable of generating GDP-glucose as well as GDP-mannose. We have therefore established how S. venezuelae can make and utilize GDP-glucose in the biosynthesis of trehalose 6-phosphate. PMID:27903647

    The genus Pterois includes nine valid species, native to the Red Sea and Indian Ocean throughout the Western Pacific. P. volitans and P. miles are native to the Indo-Pacific, and were introduced into Florida waters as a result of aquarium releases, and have been recently recognized as invaders of the Western Atlantic and Caribbean Sea (Costa Rica to Venezuela). Thus far, cytogenetic studies of the genus Pterois only cover basic aspects of three species, including P. volitans from Indo-Pacific Ocean. Considering the lack of more detailed information about cytogenetic characteristics of this invasive species, the objective of the present study was to investigate the basic and molecular cytogenetic characteristics of P. volitans in Venezuela, and compare the results with those from the original distribution area. For this, the karyotypic characteristics of four lionfish caught in Margarita Island, Venezuela, were investigated by examining metaphase chromosomes by Giemsa staining, C-banding, Ag-NOR, and two-colour-Fluorescent in situ hybridization (FISH) for mapping of 18S and 5S ribosomal genes. Comparing the sequences of the 16S gene of the specimens analyzed, with sequences already included in the Genbank, we corroborated that our specimens identified as P. volitans are in fact this species, and hence exclude the possibility of a misidentification of P. miles. The diploid number was 2n = 48 (2m + 10sm + 36a) with FN = 60. Chromosomes uniformly decreased in size, making it difficult to clearly identify the homologues except for the only metacentric pair, and the pairs number two, the largest of the submetacentric series. C-banding revealed only three pairs of chromosomes negative for C-band, whereas all remaining chromosomes presented telomeric and some interstitial C-positive blocks. Only two chromosomes were C-banding positive at the pericentromeric regions. Sequential staining revealed Ag-NOR on the tips of the short arms of chromosome pair number two and the FISH

    This paper describes a new high-resolution geoid for Venezuela and the East Caribbean Sea. The Venezuelan Gravimetric Geoid 2002 (VGG2002) covers the area between 0oN-20oN and 285oE-305oE with a resolution of 1'x1'. An additional 2o-zone was included to avoid boundary effects. About 1.5 million free-air gravity anomalies were used. They originate from PDVSA (Petróleos de Venezuela S.A.), BGI (Bureau Gravimetrique International) and the GEODAS data base of NGDC (National Geophysical Data Center). In marine areas, 1'x1' gravity anomalies derived from altimetry (S&Sv9.1) were also included. In order to determined the long wavelength geoid signal the EGM96 global geopotential model was used as reference. Short wavelength contributions were derived from a digital terrain model with 30'' (GTOPO30 model) and 2' (S&Sv8.2 model) resolution respectively. Using the GRAVSOFT software, the geoid undulations were computed with the remove-restore technique. The computation involves a spherical approximation to evaluate the Stokes integral by two dimensional spherical Fast Fourier Transform with 100% zero-padding. The terrain corrections were computed by Residual Terrain Model method using prism numeric integration and taking into account the topographic anomalies relative to a mean height surface of 15'x15' resolution. This surface was obtained by a moving average of the digital terrain model. In marine areas the height anomalies were completed by mean sea level deviations of POCM, an oceanographic model of the ocean dynamic topography. Subsequently, the quasi-geoid was converted to geoid heights. The accuracy was evaluated by about 300 GPS/leveling stations and absolute differences to TOPEX/Poseidon (nine years) mean sea surface profiles. These show that the absolute agreement with respect to the national vertical datum is generally better than 30 cm RMS for most parts of Venezuela, 15 cm RMS in coastal areas and 5 cm RMS at sea.

    Full Text Available The liberal revolutions in Spanish America are essentially the result of the adoption of modern constitutions based on the equality of citizens. In Venezuela as well as in Colombia, the new born states declared several times the rule of dictatorship and martial law. How did patriots arrive at the proclamation of the state of exception in which the army exercised the reality of power? Is the Bolivarian Cesarism the consequence of the war, the result of the strenghthening of non liberal tendencies of Liberalism, or the consequence of a resurgence of the Ancien Regime? By analysing the theme of the «fixed point», this article attempts to understand how independent elites searched to stabilize the revolution in a sustainable order, and the reasons for their failure which ultimately led to the dissolution of Gran Colombia.

    Las revoluciones liberales en América hispánica se llevaron a cabo mediante la adopción de constituciones modernas fundadas en la igualdad de los ciudadanos. A pesar de ello, en Venezuela y en Colombia se proclamaron varias veces dictaduras y la ley marcial durante las guerras de Independencia. ¿Cómo explicar, en el contexto de discursos profundamente legalistas, esta proclamación del estado de excepción que le traslada al ejército la realidad del poder? ¿El cesarismo bolivariano nace de las circunstancias de la guerra, del fortalecimiento de las tendencias no liberales del liberalismo, o se trata más bien de una resurgencia del Antiguo Régimen? Al analizar la temática del «punto fijo» en las prácticas y en los discursos de las elites independentistas, se trata de aproximarse a la manera cómo éstas buscaron estabilizar y consolidar la revolución en un orden viable y a los motivos del fracaso de estos esfuerzos que condujeron finalmente a la disgregación de la Gran Colombia.

    The benthic fauna and diel variation in a shallow seagrass bed (Thalassia testudinum) were studied in Playa Mero, Venezuela. Samples of organisms and sediments were taken using PVC cylinders, 5cm in diameter, along a transect perpendicular to the coast. Seagrass cover, shoot density and biomass were estimated. The seagrass cover was homogeneous along the transect. The intermediate zone had the highest number of shoots and of above-ground and rhizome biomass. Composition and abundance of benthic organisms were related with seagrass and sediment characteristics. Sediment organic matter content and organism abundance were highest near the shore Molluscs, polychaetes, oligochaetes and nematodes were the most abundant groups. Species richness was higher in daytime (40 versus 28 at night). Gastropods were the most abundant organisms both at day and night while polychaetes and crustaceans increased during the day, and holoturids were more numerous at night.

    The results of analyses of Z, RNA-dependent RNA polymerase, glycoprotein precursor, and nucleocapsid protein gene sequence data suggested that Guanarito virus was the most common cause of Venezuelan hemorrhagic fever in a 7-year period in the 1990’s and that the evolution of Pirital virus in association with Sigmodon alstoni (Alston’s cotton rat) has occurred at a significantly higher rate than the evolution of Guanarito virus in association with Zygodontomys brevicauda (short-tailed cane mouse) on the plains of western Venezuela. The results of analyses of the primary structures of the glycoproteins of the 8 strains of Guanarito virus isolated from humans suggested that these strains would be highly cross-reactive in neutralization assays. Thus, passive antibody therapy may prove beneficial in the treatment of human disease caused by strains of Guanarito virus that are enzootic in the region in which Venezuelan hemorrhagic fever is endemic.

Yes, we could talk about a post Modernistic Organizational Culture, and how these concepts could be interpreted in some Venezuelan organizations. Hence, a descriptive-documental research is in course. There bibliographic sources on this subject are studied. It is clear the Organizational Culture concept, but the Postmodernism concept is not, because of the contrast between theoretical positions resulting in contradictory and excluding issues. This makes difficult the characterization of a Post modernistic-Organizational Culture. Organizations like Procter & Gamble and the Electricity de Caracas have an Organizational Culture which is characteristic of private firms, centered basically to be accordingly to new eras and changing markets. Petroleos de Venezuela, traditionally dedicated to the oil business, since 1999, due to the new politic scenery, undertakes other responsibilities aimed to enhance Venezuelan Social Indicators.

    The high accuracy on inferrring of rocks properties, such as permeability ($k$), is a very useful study in the analysis of wells. This has led to development and use of empirical equations like Tixier, Timur, among others. In order to improve the inference of permeability we used a hybrid Neuro-Fuzzy System (NFS). The NFS allowed us to infer permeability of well, from data of porosity ($\\phi$) and water saturation ($Sw$). The work was performed with data from wells VCL-1021 (P21) and VCL-950 (P50), Block III, Maracaibo Lake, Venezuela. We evaluated the NFS equations ($k_{P50,i}(\\phi_i,Sw_i)$) with neighboring well data ($P21$), in order to verify the validity of the equations in the area. We have used ANFIS in MatLab.
