(Supplementary Table 1) 230Th/U results for stalagmite Cuba Grande (CG) from Pinar del Rio
2010
We present 22 U-series ages for a stalagmite from north-western Cuba based on multi-collector inductively coupled plasma mass spectrometry (MC-ICPMS) and thermal ionisation mass spectrometry (TIMS). Our results reveal that the stalagmite continuously grew within the last ~1400a. Low uranium content of the sample and thus, extremely low 230Th concentrations limit the precision and accuracy of 230Th/U-dating by TIMS. Samples measured by MC-ICPMS show a high variability of 232Th content along the growth axis with some sections significantly affected by initial 230Th from a detrital phase. An a-priori bulk earth ratio for (238U/232Th) cannot be used to accurately account for this initial 230Th.…
Microbial Community Structure and Density Under Different Tree Species in an Acid Forest Soil (Morvan, France)
2005
Overexploitation of forests to increase wood production has led to the replacement of native forest by large areas of monospecific tree plantations. In the present study, the effects of different monospecific tree cover plantations on density and composition of the indigenous soil microbial community are described. The experimental site of "Breuil-Chenue" in the Morvan (France) was the site of a comparison of a similar mineral soil under Norway spruce (Picea abies), Douglas fir (Pseudotuga menziesii), oak (Quercus sessiflora), and native forest [mixed stand dominated by oak and beech (Fagus sylvatica)]. Sampling was performed during winter (February) at three depths (0-5, 5-10, and 10-15 cm…

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.
Like ships passing in the night? Nonstandard work schedules and spousal satisfaction in Finland, the Netherlands and the United Kingdom
2020
This study examined the associations of work schedules and spousal satisfaction among Finnish (n = 347), Dutch (n = 304) and British (n = 337) parents. In addition to comparing parents with nonstandard schedule with parents in regular day work, the study examined separately the roles played in spousal satisfaction of morning, evening, night and weekend work and other working time-related variables (working hours, changes in and influence over one’s work schedules and spouse’s work schedule). The three-country data were analyzed using structural equation modeling with a multigroup procedure in Mplus. Little evidence for negative associations of work schedules and related factors with spousal…
