Data from: On the origin of mongrels: evolutionary history of free-breeding dogs in Eurasia

2015

Although a large part of the global domestic dog population is free-ranging and free-breeding, knowledge of genetic diversity in these free-breeding dogs (FBDs) and their ancestry relations to pure-breed dogs is limited, and the indigenous status of FBDs in Asia is still uncertain. We analyse genome-wide SNP variability of FBDs across Eurasia, and show that they display weak genetic structure and are genetically distinct from pure-breed dogs rather than constituting an admixture of breeds. Our results suggest that modern European breeds originated locally from European FBDs. East Asian and Arctic breeds show closest affinity to East Asian FBDs, and they both represent the earliest branching…

Influence of the Madden-Julian Oscillation on Southern African summer rainfall

2007

Rain-causing mechanisms over Southern Africa (south of 15˚S) involve both tropical and temperate dynamics. Most studies focused on the synoptical timescale, while the intraseasonal (20-120 days) variability has more been neglected to date. This study aims at determining whether the dominant mode of intraseasonal variability in the Tropics, namely the Madden-Julian Oscillation (MJO), has a significant impact on Southern African rainfall and associated atmospheric dynamics. The examination of outgoing longwave radiation (OLR) over Southern Africa shows indeed significant intraseasonal fluctuations at the 30-60 day timescale, i.e. in the pe- riods that are typically reminiscent of the MJO. In ord…

Waveforms clustering and single-station location of microearthquake multiplets recorded in the northern Sicilian offshore region

2013

In 2009 December, the OBSLab-INGV (Istituto Nazionale di Geofisica e Vulcanologia) deployed an Ocean Bottom Seismometer with Hydrophone (OBS/H) near the epicentral area of the main shock of the Palermo seismic sequence of 2002. The monitoring activity had a total duration of about 8 months. During this experiment, the OBS/H recorded 247 very local microearthquakes, whose local magnitude is between -0.5 and 2.5 and TS - TP delay time between 0.2 and 5 s, almost all ofwhichwere undetected by the Italian National Seismic Network. This local microseismicity has been analysed using an innovative clustering technique that exploits the similarity between the waveforms generated by different events…

Effect of a Killer Toxin of Yeast on Eucaryotic Systems

1988

The Saccharomyces cerevisiae killer toxin KT 28, which inhibits sensitive yeasts, was shown to have no effect on several pathogenic fungi or on the protozoan Trichomonas vaginalis. At concentrations of about 0.1 mg/ml, a partial inhibition of the skin pathogenic fungi Trichophyton rubrum and Microsporum canis was observed at pH 6.5. No pharmacological activity was detected in various tests with several animal organs.

Republicanismo y postmodernismo en los nuevos movimientos sociales. Una aproximación a los indignados

2015

Este articulo pretende explorar algunos vinculos teoricos entre el republicanismo contemporaneo y los movimientos sociales, con una aproximacion posmoderna, en la busqueda de mayor participacion, de la regeneracion democratica y de la innovacion politica, a traves de la centralidad del espacio publico como un locus politico. A partir del estudio del movimiento de indignados se abordaran las principales reivindicaciones politicas orientadas a profundizar la democracia y asumir valores civicos republicanos.

La explicación dinámica del humor como recurso preventivo en las adicciones

2003

Se destaca el método utilizado por Freud para el abordaje del humor en su paradigmática obra "El chiste y su relación con el inconsciente"; se exponen los aspectos dinámicos fundamentales del humorismo, la comicidad y el chiste; y se abordan desde ese prisma algunos chistes paradigmáticos actuales.A partir de los mecanismos defensivos subyacentes en el humor y la observación de que el estado de embriaguez persigue la reproducción de divertimentos de la infan¬cia, similares a las determinadas por los chistes, se propone: 1. que el humor incorporado de forma precoz al estilo de vida constituye un mega y multimecanismo defensivo del yo, de alta efectividad para la maduración de la personalidad…

Choix du système électoral et Convention européenne des droits de l'homme : quelques observations à la lumière d'une affaire concernant une loi élect…

2013

Within the space of less than two years the European Court of Human Rights and the Italian Constitutional Court have returned almost opposing judgments on the question of the observance of political rights by Italy’s 2005 electoral law. The ECHR found the applications made to it by groups of electors inadmissible given the manifestly ill-founded character of the grievances they were based on. The Constitutional Court, on the contrary, concluded that the law was unconstitutional. At first sight, the differing approaches by the two courts and the differing conclusions they reached may be viewed as an expression of the complementary nature of the European system of protection of human rights w…

Volcanogenic fluorine in rainwater around active degassing volcanoes: Mt. Etna and Stromboli Island, Italy

2002

Many studies have assessed the strong influence of volcanic activity on the surrounding environment. This is particularly true for strong gas emitters such as Mt. Etna and Stromboli volcanoes. Among volcanic gases, fluorine compounds are potentially very harmful. Fluorine cycling through rainwater in the above volcanic areas was studied analysing more than 400 monthly bulk samples. Data indicate that only approximately 1% of fluorine emission through the plume is deposited on the two volcanic areas by meteoric precipitations. Although measured bulk rainwater fluorine fluxes are comparable to and sometimes higher than in heavily polluted areas, their influence on the surrounding vegetation i…

MECANISMOS DE COORDINACIÓN ESTRUCTURAL, NO ESTRUCTURAL E INFORMAL. PROPUESTA Y VALIDACIÓN DE ESCALAS DE MEDIDA / STRUCTURAL, NON- STRUCTURAL AND INFO…

2008

El presente trabajo tiene como objetivo diseñar y validar escalas para medir diversos mecanismos de coordinación estructural, no estructural e informal. Los primeros están vinculados a puestos u órganos específicos, y nos referimos al diseño de redes, equipos de proyecto y desarrollo, y equipos de trabajo. Los mecanismos de coordinación no estructural sirven de complemento a los anteriores. En este grupo se encuentran la normalización de procesos de trabajo, de habilidades y de resultados. Por último, los mecanismos de carácter informal son el esfuerzo de socialización y la adaptación mutua. Tras la generación de una batería de 43 ítems, se han comprobado sus propiedades psicométricas: fiab…
