Perfil psicosocial de adolescentes españoles agresores y víctimas de violencia de pareja
2018
El objetivo de este estudio fue analizar posibles diferencias en satisfacción con la vida, ánimo depresivo, autoconcepto y comunicación familiar entre adolescentes no implicados en violencia de pareja, agresores, víctimas, implicados en el rol de agresor-víctima de forma ocasional e implicados en este rol frecuentemente. Participaron 672 adolescentes españoles (325 chicas, 347 chicos), entre 12 y 19 años (M = 14.45; DT = 1.62). Los resultados muestran un perfil psicosocial más negativo en las chicas víctimas de violencia de pareja y en los chicos implicados frecuentemente en el rol de agresor-víctima. En las chicas con mayor implicación en violencia de pareja se observan también mayores dif…
Ajuste psicosocial en adolescentes víctimas frecuentes y víctimas ocasionales de violencia de pareja
2016
El objetivo de esta investigación es analizar el ajuste psicosocial en los adolescentes víctimas de violencia de pareja, considerando posibles diferencias en función de la frecuencia de la victimización y del sexo de los adolescentes. Los indicadores del ajuste psicológico y social analizados son el ánimo depresivo, los sentimientos de soledad, el autoconcepto, la satisfacción con la vida y la calidad de la comunicación con el padre y la madre. Participaron 672 adolescentes españoles (325 chicas, 347 chicos), entre 12 y 19 años (M = 14.45; DT = 1.62). Los resultados indicaron que los adolescentes, chicos y chicas, en situación frecuente de victimización presentan menor autoconcepto familiar…
Conditional Random Quantities and Iterated Conditioning in the Setting of Coherence
2013
We consider conditional random quantities (c.r.q.’s) in the setting of coherence. Given a numerical r.q. X and a non impossible event H, based on betting scheme we represent the c.r.q. X|H as the unconditional r.q. XH + μH c , where μ is the prevision assessed for X|H. We develop some elements for an algebra of c.r.q.’s, by giving a condition under which two c.r.q.’s X|H and Y|K coincide. We show that X|HK coincides with a suitable c.r.q. Y|K and we apply this representation to Bayesian updating of probabilities, by also deepening some aspects of Bayes’ formula. Then, we introduce a notion of iterated c.r.q. (X|H)|K, by analyzing its relationship with X|HK. Our notion of iterated conditiona…
South Pole glacial climate reconstruction from multi-borehole laser particulate stratigraphy
2013
AbstractThe IceCube Neutrino Observatory and its prototype, AMANDA, were built in South Pole ice, using powerful hot-water drills to cleanly bore>100 holes to depths up to 2500 m. The construction of these particle physics detectors provided a unique opportunity to examine the deep ice sheet using a variety of novel techniques. We made high-resolution particulate profiles with a laser dust logger in eight of the boreholes during detector commissioning between 2004 and 2010. The South Pole laser logs are among the most clearly resolved measurements of Antarctic dust strata during the last glacial period and can be used to reconstruct paleoclimate records in exceptional detail. Here we use…

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…
Bayesian classification for dating archaeological sites via projectile points
2021
Dating is a key element for archaeologists. We propose a Bayesian approach to provide chronology to sites that have neither radiocarbon dating nor clear stratigraphy and whose only information comes from lithic arrowheads. This classifier is based on the Dirichlet-multinomial inferential process and posterior predictive distributions. The procedure is applied to predict the period of a set of undated sites located in the east of the Iberian Peninsula during the IVth and IIIrd millennium cal. BC.
Revealing the pace of river landscape evolution during the Quaternary: recent developments in numerical dating methods
2016
During the last twenty years, several technical developments have considerably intensified the use of numerical dating methods for the Quaternary. The study of fluvial archives has greatly benefited from these enhancements, opening new dating horizons for a range of archives at distinct time scales and thereby providing new insights into previously unanswered questions. In this contribution, we separately present the state of the art of five numerical dating methods that are frequently used in the fluvial context: radiocarbon, Luminescence, Electron Spin Resonance (ESR), 230Th/U and terrestrial cosmogenic nuclides (TCN) dating. We focus on the major recent developments for each technique th…
