Differential impact of marine debris ingestion during ontogenetic dietary shift of green turtles in Uruguayan waters
2018
Anthropogenic debris ingestion has been reported for green turtles in all their life stages worldwide. The aim of the present study is to evaluate the marine debris ingestion by green turtles stranded in Uruguayan coast between 2005 and 2013. Debris items were categorized and quantified by frequency of occurrence, relative weight, volume and number of items. A total of 96 dead stranded turtles were analyzed and 70% presented debris in their guts. The majority of debris found were plastic, being hard plastics the most abundant in weight. We found no differences in debris ingestion in stranded turtles a long the Uruguayan coast. However we detected a negative correlation between the presence …
DNA multigene characterization of Fasciola hepatica and Lymnaea neotropica and its fascioliasis transmission capacity in Uruguay, with historical cor…
2017
Background Fascioliasis is a pathogenic disease transmitted by lymnaeid snails and recently emerging in humans, in part due to effects of climate changes, anthropogenic environment modifications, import/export and movements of livestock. South America is the continent presenting more human fascioliasis hyperendemic areas and the highest prevalences and intensities known. These scenarios appear mainly linked to altitude areas in Andean countries, whereas lowland areas of non-Andean countries, such as Uruguay, only show sporadic human cases or outbreaks. A study including DNA marker sequencing of fasciolids and lymnaeids, an experimental study of the life cycle in Uruguay, and a review of hum…
Côté mauvaises herbes, tir de barrage sur trois envahissantes
2006
National audience; Les plantes envahissantes sont évoquées à la conférence sur les zones non agricoles de l'AFPPà Avignon les 11 et 12octobre 2006. La situation à leur égard en France et en Europe est présentée, notamment les dispositions réglementaires et l'identité des 34 principales espèces. Deux communications traitent de l'ambroisie à feuille d'armoise Ambrosia artemisiifolia. Un point sur les méthodes de lutte mécanique, chimique, etc.) insiste sur l'intérêt de la prévention (enherbement, etc.)et de la concertation entre acteurs agricoles et non agricoles. Des essais de lutte chimique (glyphosate ou glufosinate-ammonium en 2004 et 2005, les montrent équivalents et intéressants en débu…
Mobbing in Schools and Hospitals in Uruguay: Prevalence and Relation to Loss of Status.
2017
In the present study in secondary schools and hospitals in Uruguay ( N = 187), we examined the relationship between feeling the victim of mobbing and a perceived loss of status. Nearly all forms of mobbing were more prevalent among hospital employees than among school employees. Among hospital employees, 40.4%, and among school employees, 23.9% reported being the victim of mobbing at least once a week. Being the victim of mobbing was, in both hospitals and schools, more prevalent among older employees, and in hospitals, among employees who were more highly educated and who had been employed for a longer time. Men and women did not differ in reporting that one was a victim of mobbing, but m…
Prospective Multinational Study of Pertussis Infection in Hospitalized Infants and Their Household Contacts
2007
Increased incidence of pertussis has been noted among infants too young to be immunized. We studied the disease burden of pertussis in pediatric intensive care units and the source of infection in several Asian, European and Latin American countries.The study was conducted in 7 countries from September 2001 to January 2004. Children1 year of age were enrolled from pediatric intensive care units (PICU) and pediatric wards if they presented with respiratory failure, apnea, bradycardia, or cough accompanied by paroxysms, vomiting, whoop or cyanosis. Household members of pertussis-positive index cases were asked to answer a questionnaire and provide diagnostic specimens.Pertussis was confirmed …
El arte del desgarro en el Uruguay de la Represión. Imposibilidades, vacíos y tensiones en la obra de Horacio Faedo.
2014
Resumen: Este trabajo intenta considerar algunas de las producciones del artista Horacio Faedo en relacion a la experiencia concentracionaria dentro del contexto de la dictadura uruguaya. Partiendo del analisis de las especificidades de este sistema represivo y su influencia en la propia individualidad, se pretenderan desentranar algunas de las claves para un mejor entendimiento de sus obras, que litigan entre la figuracion y la abstraccion, el vacio y la corporalidad, el testimonio y su imposibilidad. Palabras clave: Arte uruguayo, Dictadura, Horacio Faedo. Abstract: This article attempts to contemplate some productions of the Uruguayan artist Horacio Faedo, regarding to the concentration …
Scad-elastic net and the estimation of individual tourism expenditure determinants
2014
This paper introduces the use of scad-elastic net in the assessment of the determinants of individual tourist spending. This technique approaches two main estimation-related issues of primary importance. So far studies of tourism literature have made a wide use of classic regressions, whose results might be affected by multicollinearity. In addition, because of the absence of robust economic theory on tourism behavior, regressor selection is often left to researcher's choice when not driven by non-optimal automatic criteria. Scad-elastic net is an OLS model that accounts for both these problems by including two types of parameters constraints, namely the smoothly clipped absolute deviation …
Genetic variability ofTriatoma rubrovaria(Reduviidae: Triatominae) from Brazil, Argentina and Uruguay as revealed by two different molecular markers
2007
Randomly amplified polymorphic DNA (RAPD) and nuclear ribosomal DNA sequence analyses were used to assess the genetic population structure of the South American triatomine species Triatomo rubrovario throughout its geographical distribution. To investigate the genetic variability at both intraspecific and intrapopulational levels the RAPD profiles and the nucleotide sequences of the rDNA intergenic spacers, ITS-1 and ITS-2, were analysed and compared. The phenetic analysis based on RAPD profiles show three distinct clusters diverging by similarity coefficients ranging from 0.62 to 0.96. The ITS-1 and ITS-2 sequence variability detected may be considered very high, suggesting reproductive is…
Management and research on plastic debris in Uruguayan Aquatic Systems: update and perspectives
2015
Synthetic plastics have become an indispensable component of modern life, and the amount of plastics disposal has increased dramatically as a result. With human population increasing, it is expected that the prevalence of plastic debris in the environment will also increase, unless sustainable daily habits are incorporated, waste management improved, and new alternative materials are discovered and popularized. To date, several reports show negative effects of plastic debris on marine and freshwater fauna (e.g. invertebrates, birds, turtles, marine mammals). Plastic are ubiquitous in the water column, deposited in fine sediments and enter the guts, respiratory structures and tissues of diff…
Nietzsche no Uruguai, 1890-1910
2014
Este artigo mostra a recepção e a influência de Nietzsche no Uruguai durante os anos de 1890 a 1910. Para tal, o artigo se divide em três partes. Em primeiro lugar, se expõem as diferentes vias pelas quais se introduz Nietzsche, como chega? como era lido? quem o lia? A segunda parte investiga as traduções francesas e espanholas que chegaram ao Uruguai. E, por ultimo, se expõem as diferentes revistas culturais da época que abordaram Nietzsche. This paper shows the reception and influence of Nietzsche in Uruguay during the years 1890 to 1910. For this purpose, the paper is divided into three parts.
