Cohort Differences in Depressive Symptoms and Life Satisfaction in 75- and 80-Year-Olds : A Comparison of Two Cohorts 28 Years Apart
2023
Objectives To examine birth cohort differences in depressive symptoms and life satisfaction in older men and women and the mechanisms underpinning the possible cohort differences. Methods Two independent cohorts of Finnish men and women aged 75 and 80 were assessed in 1989–1990 ( n = 617) and 2017–2018 ( n = 794). They reported their depressive symptoms (CES-D), current life satisfaction, and evaluation of life until now. Results The later-born cohort reported fewer depressive symptoms (8.6 ± 7.1 vs. 13.9 ± 8.3) and the differences were similar for the subdomains of depressive symptoms. The later-born cohort was more often mostly satisfied with life until now (90 vs. 70%) but not with the c…
Durum wheat yield uncertainty under different tillage management practices and climatic conditions
2019
Abstract In the field of conservative agriculture, no-till (NT) management has been receiving increasing interest, with 45 million ha of land under no-till management in 1999 to 155 million ha in 2014. Up until now, no-till has only been observed to perform better under rainfed conditions, especially in dry climates mainly because the reduced tillage system retains more soil moisture. However, the adoption of alternative agricultural practices (NT) can be improved only if uncertain and consequent assumption of risk is well known and accepted. For these reasons, the aim of this research is (i) to define durum wheat suitability under NT soil management in terms of yield success probability an…
Affinities of European Upper Palaeolithic Homo sapiens and later human evolution
1992
Abstract We investigate the evolutionary affinities of European Upper Palaeolithic populations, using cranial measurements and multivariate techniques. Results indicate that cranial morphology of these populations accords with long-term phyletic trends within Pleistocene hominids. The data indicate an interpretation of differential velocities of change, and results do not support the view that Neanderthals contributed to recent populations.

Domestic and International Tourism in Sicilian Bathing Resorts: Evidences from Official and Ad-hoc Survey Data
2010
Similarly to other social phenomena, tourism demand has recently been affected by social complexity: travellers select destinations on the basis of situational and mixed preference criteria, of which common features are however identifiable. In order to plan tourism policies, decision makers are wondering how the new trends of international tourism materialize at the local level. That’s why in Sicily the debate is still open on the reasons why tourism has not developed as much as expected. In this paper we shall discuss such arguments using both official statistics and data from the sample researches made in 2004 and 2005 in two well-known Sicilian bathing resorts, the Aeolian Islands and C…
BioTIME: A database of biodiversity time series for the Anthropocene
2018
Abstract Motivation The BioTIME database contains raw data on species identities and abundances in ecological assemblages through time. These data enable users to calculate temporal trends in biodiversity within and amongst assemblages using a broad range of metrics. BioTIME is being developed as a community-led open-source database of biodiversity time series. Our goal is to accelerate and facilitate quantitative analysis of temporal patterns of biodiversity in the Anthropocene. Main types of variables included The database contains 8,777,413 species abundance records, from assemblages consistently sampled for a minimum of 2 years, which need not necessarily be consecutive. In addition, th…
Dendroarchaeological contributions to the history of forest exploitation: the case of the Gallo-roman settlement of Oedenburg (Alsace, France) betwee…
2011
International audience; Dendro-archaeological contribution to the history of forest exploitation. The case of the Gallo-Roman settlement of Oedenburg (Alsace, France) between 10 and 180 AD summary Dendrochronology has never been considered as simply a dating tool. In addition to the dates, which are always based on a regional scale signal, tree-ring series can provide information about forest structure and woodland development. Our study of the settlement of Oedenburg, established in the Rhine Limes of the Roman Empire, was conducted within this framework. The dated series provide a description of some structural aspects of oak-stands that were exploited for construction. In this aim, the a…
Streamwater responses to reduced nitrogen deposition at four small upland catchments in Norway
2020
AbstractReduced emissions of nitrogen (N) in Europe have resulted in decreasing atmospheric deposition since 1990. Long-term data (1988–2017) from four small Norwegian catchments located along gradients in N deposition, rainfall, and organic carbon (C) show different responses to 25–30% reductions in N deposition during the same period. At three sites the decreased N deposition caused reduced leaching of nitrate to surface water, whereas the westernmost site showed no decrease, probably due to thin soils with low C:N ratio, poor vegetation cover and high precipitation. The loss of total N to streamwater constituted 30–50% of the N deposition. Losses via denitrification are unknown but assum…
