Il lichene e la farfalla. Sbarbaro e Gozzano fra scienza e poesia
2011
Originale confronto fra il naturalismo lirico di Sbarbaro e l’entomologia poetica di Gozzano. Entrambi accomunati da un interesse scientifico-sentimentale per le più inconsistenti forme di vita naturale – il lichene e la farfalla – i due poeti si distinguono tuttavia per una diversa declinazione della loro passione: è sufficiente scorrere i sei inventari lichenologici redatti dal poeta ligure per accertarsi dell’impiego di un formulario tecnico privo di qualunque orpello estetizzante o astrattizzante, com’è possibile rinvenire ancora negli scritti gozzaniani.

Importancia del fallo orgánico de inicio en la evolución de la pancreatitis aguda
2016
Se ha estimado que la pancreatitis aguda (PA) tiene una mortalidad en torno al 5%, siendo practicamente nula en las PA leves y llegando al 30%-50% en las PA graves. Se ha determinado que el fallo orgánico (FO) y la infección de la necrosis pancreática son los dos principales determinantes de la mortalidad. Se ha observado que el FO que se resuelve en 48 horas o menos (FO transitorio) tiene mejor pronóstico que el FO que se prolonga durante más de 48 horas (FO persistente). No existen estudios que valoren la importancia del FO de inicio (FOI) que se desarrolla en las primeras 48 horas tras el ingreso. En nuestra serie de 901 pacientes observamos que los pacientes con FOI persistente presenta…
GARCH models with changes in variance: An approximation to risk measurements
2003
This study aims to model volatility as an approximation to an optimum measurement of stock market risk because of the importance of this concept for, among other things, the proper management of portfolios. Following the proposal of Lamoureux and Lastrapes (1990), the authors consider that the high degree of persistence detected in GARCH models arises from a poor specification of the equation of the variance due to not considering the possible deterministic changes in the unconditional variance of the financial series. To determine the point in time as well as the duration of these changes, the proposal made by Inclan and Tiao (1994) is used. As an empirical application, whether or not the …
The importance of the moss layer in sustaining biological diversity of Gamasina mites in coniferous forest soil
2008
Summary The feather moss layer of boreal coniferous forests is known to buffer the underlying soil temperature and to be a major component in the nitrogen and phosphorus cycles by efficient scavenging of nutrients from throughfall and direct precipitation. Through indirect or direct effects the feather moss layer may also play a significant role in forming soil organism communities. In this 4-year experimental field study, the predatory Gamasina mite diversity was estimated in plots where the feather moss layer was removed or disturbed by turning over, in relation to that in control plots. Species richness, Shannon's diversity and equitability in spring but not autumn were decreased when th…
Bioclimatic atlas of the terrestrial Arctic
2023
AbstractThe Arctic is the region on Earth that is warming at the fastest rate. In addition to rising means of temperature-related variables, Arctic ecosystems are affected by increasingly frequent extreme weather events causing disturbance to Arctic ecosystems. Here, we introduce a new dataset of bioclimatic indices relevant for investigating the changes of Arctic terrestrial ecosystems. The dataset, called ARCLIM, consists of several climate and event-type indices for the northern high-latitude land areas > 45°N. The indices are calculated from the hourly ERA5-Land reanalysis data for 1950–2021 in a spatial grid of 0.1 degree (~9 km) resolution. The indices are provided in three subsets…
Re-evaluation of moisture sources for the August 2002 extreme rainfall episode in central Europe: Evaporation from falling precipitation included in …
2015
Summary Discriminating moisture sources with precision is an important requirement to better understand the processes involved in extreme rainfall episodes. In a previous contribution by Gangoiti et al. (2011b), an innovative technique was presented to assess surface moisture sources contributing to a target precipitation within a Lagrangian framework. The technique was based in transporting parcels of vapor, representing the target precipitation, across a set of nested grids covering a large area at different resolutions. A mesoscale model estimated the meteorological variables to transport and redistribute the vapor back into its original sources, all of them assumed to be at the surface.…
The balancing act: How do moral norms and anticipated pride drive food waste/reduction behaviour?
2022
Food waste is a serious problem that impacts the environment and sustainability by increasing greenhouse gas emissions from landfills. Food waste also represents a social challenge because it raises serious concerns about food security. While acknowledging that households waste a great deal of food because they lack a proper routine for reusing leftovers and purchase more food than required, few studies have extensively examined the drivers of leftover reuse and over-ordering. We address this gap using the stimulus-organism-response paradigm. Moral norms and anticipated pride are conceptualised as stimuli that impact the organismic state of intentions against food waste and response in the …
