La comunicación: disciplina y campo de estudio. La experiencia latina
2011
La investigación en comunicación presenta una serie de particularidades que le otorgan un interés específico y una cierta capacidad de adaptación a la hora de analizar los fenómenos sociales. Se trata de una disciplina y un campo de estudio a la vez, lo que implica una necesaria transdisciplinariedad en el proceso de estudio de los paradigmas sociales y de formación de los profesionales de la comunicación. Esta adaptación de los estudios de comunicación supone una redefinición de las características propias de cada contexto, especialmente si se ha de llevar a cabo este estudio en América latina y en la Europa latina (Francia, Portugal, España e Italia). Su consideración como un espacio prop…
La contrattazione collettiva in Europa del Sud al tempo della crisi: aziendalizzazione, europeizzazione, americanizzazione
2018
Il saggio analizza i recenti sviluppi della contrattazione collettiva in Europa del Sud all’insegna del trinomio aziendalizzazione-europeizzazione-americanizzazione: nonostante le differenze strutturali, i sistemi analizzati hanno notevolmente rafforzato il ruolo del contratto aziendale nel sistema delle fonti rispetto alla legge e al contratto nazionale, oltre che funzionalizzato la rappresentanza dei lavoratori in azienda a meccanismi di verifica effettiva del consenso. Tale traiettoria, frutto della governanceeconomica europea quale risposta alla crisi, porta a una convergenza funzionale dei sistemi sud-europei verso quello statunitense, ove prevale la regolazione di prossimità. The essa…
Dataset for the manuscript "Are remote sensing evapotranspiration models reliable 2 across South American ecoregions?" published in WRR
2021
Metadata of ‘Are remote sensing evapotranspiration models reliable across South American ecoregions?’ This document describes the file formatting and data used to run and evaluate the evapotranspiration models in this study. Because forcing data varies among models, each input file contains a different set of meteorological data placed within a folder named after the corresponding model. File format and time stamps Data files are CSV formatted with timestamps in the first column of the file. The following timestamps are used: GLEAM: Year (YYYY); Day of Year (DDD) PT-JPL: Year (YYYY); Month (MM); Day (DD) PM-MOD: Year (YYYY); Month (MM); Day (DD) PM-VI: Date (MM/DD/YYYY) Missing data Missing…
Reconstruction of the evolutionary history of Saccharomyces cerevisiae x S. kudriavzevii hybrids based on multilocus sequence analysis.
2012
In recent years, interspecific hybridization and introgression are increasingly recognized as significant events in the evolution of Saccharomyces yeasts. These mechanisms have probably been involved in the origin of novel yeast genotypes and phenotypes, which in due course were to colonize and predominate in the new fermentative environments created by human manipulation. The particular conditions in which hybrids arose are still unknown, as well as the number of possible hybridization events that generated the whole set of natural hybrids described in the literature during recent years. In this study, we could infer at least six different hybridization events that originated a set of 26 S…
Personal protective equipment and intensive care unit healthcare worker safety in the COVID-19 era (PPE-SAFE): An international survey
2020
Purpose To survey healthcare workers (HCW) on availability and use of personal protective equipment (PPE) caring for COVID-19 patients in the intensive care unit (ICU). Materials and method A web-based survey distributed worldwide in April 2020. Results We received 2711 responses from 1797 (67%) physicians, 744 (27%) nurses, and 170 (6%) Allied HCW. For routine care, most (1557, 58%) reportedly used FFP2/N95 masks, waterproof long sleeve gowns (1623; 67%), and face shields/visors (1574; 62%). Powered Air-Purifying Respirators were used routinely and for intubation only by 184 (7%) and 254 (13%) respondents, respectively. Surgical masks were used for routine care by 289 (15%) and 47 (2%) for…
Remote sensing and climate data as a key for understanding fasciolosis transmission in the Andes: review and update of an ongoing interdisciplinary p…
2006
Fasciolosis caused by Fasciola hepatica in various South American countries located on the slopes of the Andes has been recognized as an important public health problem. However, the importance of this zoonotic hepatic parasite was neglected until the last decade. Countries such as Peru and Bolivia are considered to be hyperendemic areas for human and animal fasciolosis, and other countries such as Chile, Ecuador, Colombia and Venezuela are also affected. At the beginning of the 1990s a multidisciplinary project was launched with the aim to shed light on the problems related to this parasitic disease in the Northern Bolivian Altiplano. A few years later, a geographic information system (GIS…
Financing public higher education in developing countries : the potential role of loan schemes
1986
The financing of education has emerged as a major topic of discussion among policy makers in recent years. There is evidence that in many developing countries, governments can no longer continue to increase spending on education at the high rates characteristic in the 1960s and 1970s. The macroeconomic environment has worsened, and there is keen intersectoral competition for public funds. Thus unless educational development moves away from its present heavy dependence on public funds, the expansion of education would be frustrated. One policy option is to increase the private financing of education. In this paper, we evaluate the potential effectiveness of loans schemes as a cost recovery i…
Regional and global contributions of air pollution to risk of death from COVID-19
2020
Abstract Aims The risk of mortality from the coronavirus disease that emerged in 2019 (COVID-19) is increased by comorbidity from cardiovascular and pulmonary diseases. Air pollution also causes excess mortality from these conditions. Analysis of the first severe acute respiratory syndrome coronavirus (SARS-CoV-1) outcomes in 2003, and preliminary investigations of those for SARS-CoV-2 since 2019, provide evidence that the incidence and severity are related to ambient air pollution. We estimated the fraction of COVID-19 mortality that is attributable to the long-term exposure to ambient fine particulate air pollution. Methods and results We characterized global exposure to fine particulates…
Hospitalisation and length of hospital stay following first-episode psychosis:Systematic review and meta-analysis of longitudinal studies
2019
AbstractBackgroundReducing hospitalisation and length of stay (LOS) in hospital following first episode psychosis (FEP) is important, yet reliable measures of these outcomes and their moderators are lacking. We conducted a systematic review and meta-analysis to investigate the proportion of FEP cases who were hospitalised after their first contact with services and the LOS in a hospital during follow-up.MethodsStudies were identified from a systematic search across major electronic databases from inception to October 2017. Random effects meta-analyses and meta-regression analyses were conducted.Results81 longitudinal studies encompassing data for 23 280 FEP patients with an average follow-u…
Anti-inflammatory Effects of South American Tanacetum vulgare
1998
Abstract In recent years the role of phenolic compounds and sesquiterpene lactones, particularly parthenolide, in the anti-migraine and anti-inflammatory effects of Tanacetum parthenium (Asteraceae) has attracted much attention. However, the closely-related cosmopolitan species T. vulgare has remained outside the mainstream of research in this field. After treating the aerial parts of T. vulgare with dichloromethane and methanol, and applying conventional column and thin-layer chromatographic techniques, it was possible to isolate from the moderately lipophilic fractions the principles responsible for the anti-inflammatory activity of this plant against the mouse-ear oedema induced by 12-O-…
