Influencia del acceso abierto en las revistas de América Latina en el contexto internacional de la ciencia

El Acceso Abierto en la comunicación académica se viene desarrollando por dos grandes vías: la ruta verde y la ruta dorada. Algunos estudios analizan la extensión y la magnitud de este fenómeno, pero pocos muestran los efectos en términos de impacto y visibilidad. Nuestro objetivo es analizar estos efectos desde la perspectiva del modelo económico de las revistas incluidas en la base de datos Scopus, en Latinoamérica. Los resultados muestran que tanto a nivel internacional como temático, la presencia de las revistas que contribuyen al desarrollo de la "ruta verde" sobrepasan el porcentaje de las revistas de la ruta dorada. Mientras en las regiones periféricas y emergentes, estas últimas revistas predominan ocupando las últimas posiciones de las distribuciones de impacto

Se presenta un avance de investigación para estimar el acceso abierto real y potencial en las prácticas de publicación de la comunidad científica argentina a partir del análisis del modelo de acceso de las revistas donde publican los investigadores. En esta primera etapa se estudia el campo de la medicina a partir de las publicaciones de 2008-2010 incluidas en la base de datos SCOPUS, y de la consulta a las fuentes DOAJ, e-revist@s, SCielo, Redalyc, PubMed, Romeo-Sherpa y Dulcinea. Asimismo se analiza la accesibilidad de la producción por la vía de suscripción a través de la Biblioteca Electrónica de Ciencia y Tecnología del Ministerio de Ciencia, Tecnología e Innovación Productiva de la Nación Argentina.

Chiral gold(I) vs chiral silver complexes as catalysts for the enantioselective synthesis of the second generation GSK-hepatitis C virus inhibitor

The synthesis of a GSK 2nd generation inhibitor of the hepatitis C virus, by enantioselective 1,3-dipolar cycloaddition between a leucine derived iminoester and tert-butyl acrylate, was studied. The comparison between silver(I) and gold(I) catalysts in this reaction was established by working with chiral phosphoramidites or with chiral BINAP. The best reaction conditions were used for the total synthesis of the hepatitis C virus inhibitor by a four step procedure affording this product in 99% ee and in 63% overall yield. The origin of the enantioselectivity of the chiral gold(I) catalyst was justified according to DFT calculations, the stabilizing coulombic interaction between the nitrogen atom of the thiazole moiety and one of the gold atoms being crucial.

Ethnobotanic importance of plants used in pigeon-breeding in Eastern Spain

Background: The importance that birds of the Columbidae family have had throughout history is visible on the Mediterranean coast. Pigeon fancying is the art of breeding and training carrier pigeons and currently, several breeds exist. The sport of racing pigeons consists in covering a distance at maximum possible speed. However, pigeon breeding has another modality called “sport pigeon”, where several males follow a female. This study focusses on ethnobotanical knowledge of native and exotic plant species that are used for diet, breeding, stimulation, healing illnesses and staining the plumage of pigeons bred in captivity. Methods: Using semi-structured interviews, we gathered information about the different plant species traditionally used for pigeon-breeding in the region of Valencia. Background material on remedies for bird illnesses was gathered from folk botanical references, local books and journals. The plant species were collected in the study area, then identified in the laboratory using dichotomous keys and vouchered in the ABH (Herbarium of Alicante University). We used Excel ® 2003 to perform a simple statistical analysis of the data collected. Results: We collected 56 species of plants (and one variety) that included 29 botanical families. The total number of species was made up of 35 cultivated and 21 wild plants. The most common were Gramineae (14 species), Leguminosae (6 species), and Compositae (4 species). Conclusions: Pigeon breeding is an immensely popular activity in Eastern Spain, and ethnobiological knowledge about breeding pigeons and caring for them is considerable. The names and traditional uses of plants depend on their geographical location, vernacular names serve as an intangible heritage. Feeding, environmental features, and genetic makeup of individuals are relevant aspects in the maintenance of avian health.

Gender-sensitive reporting in medical research

Sex and gender differences influence the health and wellbeing of men and women. Although studies have drawn attention to observed differences between women and men across diseases, remarkably little research has been pursued to systematically investigate these underlying sex differences. Women continue to be underrepresented in clinical trials, and even in studies in which both men and women participate, systematic analysis of data to identify potential sex-based differences is lacking. Standards for reporting of clinical trials have been established to ensure provision of complete, transparent and critical information. An important step in addressing the gender imbalance would be inclusion of a gender perspective in the next Consolidated Standards of Reporting Trials (CONSORT) guideline revision. Uniform Requirements for Manuscripts Submitted to Biomedical Journals, as a set of well-recognized and widely used guidelines for authors and biomedical journals, should similarly emphasize the ethical obligation of authors to present data analyzed by gender as a matter of routine. Journal editors are also promoters of ethical research and adequate standards of reporting, and requirements for inclusion of gender analyses should be integrated into editorial policies as a matter of urgency.

Synthetic scope and DFT analysis of the chiral binap-gold (I) complex-catalyzed 1,3-dipolar cycloaddition of azlactones with alkenes

The 1,3-dipolar cycloaddition between glycine-derived azlactones with maleimides is efficiently catalyzed by the dimeric chiral complex [(Sa)-Binap·AuTFA]2. The alanine-derived oxazolone only reacts with tert-butyl acrylate giving anomalous regiochemistry, which is explained and supported by Natural Resonance Theory and Nucleus Independent Chemical Shifts calculations. The origin of the high enantiodiscrimination observed with maleimides and tert-butyl acrylate is analyzed using DFT computed at M06/Lanl2dz//ONIOM(b3lyp/Lanl2dz:UFF) level. Several applications of these cycloadducts in the synthesis of new proline derivatives with a 2,5-trans-arrangement and in the preparation of complex fused polycyclic molecules are described.

Changes in Access to Health Services of the Immigrant and Native-Born Population in Spain in the Context of Economic Crisis

Aim: To analyze changes in access to health care and its determinants in the immigrant and native-born populations in Spain, before and during the economic crisis. Methods: Comparative analysis of two iterations of the Spanish National Health Survey (2006 and 2012). Outcome variables were: unmet need and use of different healthcare levels; explanatory variables: need, predisposing and enabling factors. Multivariate models were performed (1) to compare outcome variables in each group between years, (2) to compare outcome variables between both groups within each year, and (3) to determine the factors associated with health service use for each group and year. Results: unmet healthcare needs decreased in 2012 compared to 2006; the use of health services remained constant, with some changes worth highlighting, such as the decline in general practitioner visits among autochthons and a narrowed gap in specialist visits between the two populations. The factors associated with health service use in 2006 remained constant in 2012. Conclusion: Access to healthcare did not worsen, possibly due to the fact that, until 2012, the national health system may have cushioned the deterioration of social determinants as a consequence of the financial crisis. Further studies are necessary to evaluate the effects of health policy responses to the crisis after 2012.

Evidence for non-conservative current-induced forces in the breaking of Au and Pt atomic chains

This experimental work aims at probing current-induced forces at the atomic scale. Specifically it addresses predictions in recent work regarding the appearance of run-away modes as a result of a combined effect of the non-conservative wind force and a ‘Berry force’. The systems we consider here are atomic chains of Au and Pt atoms, for which we investigate the distribution of break down voltage values. We observe two distinct modes of breaking for Au atomic chains. The breaking at high voltage appears to behave as expected for regular break down by thermal excitation due to Joule heating. However, there is a low-voltage breaking mode that has characteristics expected for the mechanism of current-induced forces. Although a full comparison would require more detailed information on the individual atomic configurations, the systems we consider are very similar to those considered in recent model calculations and the comparison between experiment and theory is very encouraging for the interpretation we propose.

Los diez artículos más citados de la revista “Nutrición Hospitalaria”

Después de 36 años de publicación ininterrumpida de la revista Nutrición Hospitalaria, hemos recopilado los diez artículos más citados. Se muestra también la relación de los diez artículos con más citas a escala mundial; asimismo se estratifican las citaciones según el idioma, inglés o español, la temática o los años analizados. Nutr. Hosp. es, a nivel mundial, la revista de nutrición ibero-latinoamericana mejor valorada. Por el volumen de artículos publicados, con 369 ítems citables en 2014, Nutr Hosp se sitúa en cuarto lugar de todas las revistas de nutrición. Permitir la publicación de artículos en inglés o hacerlo simultáneamente en castellano y en inglés, así como estar en régimen de “Open Access” sin restricción de ningún tipo en la difusión desde el momento de aparición de los artículos, son probablemente elementos favorecedores de las citas.

Perfeccionismo durante la infancia y la adolescencia. Análisis bibliométrico y temático (2004-2014)

El perfeccionismo es un rasgo de la personalidad caracterizado por la imposición a uno mismo de unas normas de desempeño poco realistas, la motivación por ser perfeccionista y la percepción del entorno como demasiado exigente y crítico. Este estudio tuvo por objeto analizar la literatura científica sobre perfeccionismo en niños y adolescentes, publicada en 4 bases de datos (Web of Science, Scopus, PsycINFO y Education Resources Information Center), entre el año 2004 y el 2014. Se obtuvieron 325 documentos que fueron analizados con base en distintos indicadores bibliométricos, como el análisis de la producción temporal, las revistas y autores más productivos sobre el tópico y el índice de coautoría, así como un análisis y discusión de las características de la población, los principales instrumentos empleados y las temáticas identificadas. Se halló una tendencia a elaborar los trabajos en colaboración y un número considerable de grandes productores (Gordon L. Flett, Paul L. Hewitt, Andrew P. Hill y Bart Soenens). Destacaron la Frost Multidimensional Perfectionism Scale y la Child and Adolescent Perfectionism Scale como los 2 instrumentos más empleados para evaluar el perfeccionismo en niños y adolescentes. Igualmente, prevalecieron los estudios realizados en adolescentes frente a aquellos con participantes de población infantil. Se observó que la mayor parte de los documentos analizados se centraron en analizar la relación entre el perfeccionismo y la psicopatología. Por último, se discuten las temáticas identificadas, las limitaciones encontradas y los aspectos consolidados, sirviendo como referencia para la realización de futuros estudios sobre el campo del perfeccionismo durante la infancia y la adolescencia.
