Global distributions of diazotrophs abundance, biomass and nitrogen fixation rates - Gridded data product (NetCDF) - Contribution to the MAREDAT Worl…
2012
The MAREDAT atlas covers 11 types of plankton, ranging in size from bacteria to jellyfish. Together, these plankton groups determine the health and productivity of the global ocean and play a vital role in the global carbon cycle. Working within a uniform and consistent spatial and depth grid (map) of the global ocean, the researchers compiled thousands and tens of thousands of data points to identify regions of plankton abundance and scarcity as well as areas of data abundance and scarcity. At many of the grid points, the MAREDAT team accomplished the difficult conversion from abundance (numbers of organisms) to biomass (carbon mass of organisms). The MAREDAT atlas provides an unprecedente…
CONSTRUCTING, BOOTSTRAPPING, AND COMPARING MORPHOMETRIC AND PHYLOGENETIC TREES: A CASE STUDY OF NEW WORLD MONKEYS (PLATYRRHINI, PRIMATES)
2005
Morphometric data sets are often phenetically analyzed by using various kinds of spatial, metric, or nonmetric multivariate analyses. Such methods produce results that are difficult to compare directly with molecular or morphological phylogenetic hypotheses, which are usually expressed by using nonspatial tree representations. Therefore, it is useful in a comparative approach to analyze, and above all to visualize, morphometric pairwise relationships as tree structures. For this purpose, several additive or ultrametric methods exist, which often return different topologies for the same data set. Objective criteria are thus needed to identify the tree-building algorithm (or algorithm family)…
Geovisualizing the sail-to-steam transition through vessel movement data
2017
International audience; Technological transitions in the maritime and port industries go along with increased transport and economic efficiency, resulting in faster movements and longer travelled distances. Yet, such transformations may also enhance disparities between winners and loosers, should they be ports or shipping companies. This research focuses on the particular case of the transition from sail to steam over the period 1890-1925, which witnesses the rapid replacement of sailing vessels, the latter concentrating 65% of the world fleet in 1890 but only 3.5% in 1925. It applies a variety of measures to compare how these two layers overlap in the network (at links and ports) and what …
Pathways fostering mobility to higher education for vulnerable immigrants in France, Switzerland and Canada
2016
In this article we wish to clarify not only if, but also how – through which institutional settings – higher education is accessed by students from vulnerable immigrant groups in France, Switzerland and Canada. We are interested in the possible educational mobility that immigrant youths can experience arising from country-specific educational policies designed to increase the enrolment in higher education, particularly the flow from upper-secondary vocational educational tracks to higher education ones. We analyse using panel data in each country the accessibility of different pathways to higher education while taking into account the characteristics of the students. In terms of educational…
Diversification of old-age care services for older people: Trade-offs between coverage, diversification and targeting in European countries.
2011
Information on public services for older people is often limited to institutional care and Home Help/ Home Care, be it for individuals in surveys, statistics for a specific country or for international comparisons. Yet, these two major services in many countries are supplemented — or substituted — by other, minor services. The latter include services such as transportation services, meals-on-wheels, alarm systems, and day care. In this study the authors use various data sources to provide information on all or most of these types of support for Denmark, Norway, Sweden, Germany, England, Spain, and Israel, concluding with a closer scrutiny of Swedish service profiles. When all types of suppo…
Inequalities in educational opportunities in France: educational expansion, democratization or shifting barriers?
2000
International audience; This paper is concerned with inequalities in educational opportunities in France and presents data collected from cohorts born between 1919 and 1973, a period characterized by educational expansion. Data from large-scale representative French surveys were compiled in such a way as to make accurate historical and international comparisons possible. The paper argues that there has been a shift in social inequalities, from entry into collège (lower secondary school) to entry into lycée (upper secondary school leading to the baccalauréat). Finally, policy implications have been drawn from international comparisons of data on the reduction of social inequality. Cet articl…
Digital ageing in Europe: a comparative analysis of Italian, Finnish and Swedish national policies on eHealth
2023
AbstractAgeing Europeans are today healthier than previous generations and often manage to live independently up to a high age. The proportion of people 80 years of age and older has increased significantly, and with high age the risk of multi-illness and dementia increases. Strong urbanisation processes have changed the demographic structure in rural areas, and young women and men have migrated towards the urban areas to study and work, while older persons have remained behind. This demographic challenge of increasing numbers of persons older than 80 years with care needs living in remote rural areas has become a major European social problem. In tackling this dilemma, many European countr…
An international cohort comparison of size effects on job growth
2015
The contribution of different-sized businesses to job creation continues to attract policymakers’ attention, however, it has recently been recognized that conclusions about size were confounded with the effect of age. We probe the role of size, controlling for age, by comparing the cohorts of firms born in 1998 over their first decade of life, using variation across half a dozen northern European countries Austria, Finland, Germany, Norway, Sweden, and the UK to pin down size effects. We find that a very small proportion of the smallest firms play a crucial role in accounting for cross-country differences in job growth. A closer analysis reveals that the initial size distribution and surviv…
The importance of consecutive spells of poverty: a path-dependent index of longitudinal poverty
2011
In this paper we propose a new index of individual poverty in the longitudinal perspective, taking into account the way poverty and non-poverty spells follow one another along individual life courses. The Poverty Persistence Index (PPI) is based on all the pairwise distances between the waves of poverty. The PPI is normalized and it assigns a higher degree of (longitudinal) poverty to people who experience poverty in consecutive, rather than separated, periods, for whom the distances from the poverty line are larger along time and moreover, when the worst years are consecutive and/or recent. We also propose an aggregate index of persistence in poverty (APPI) in order to measure the distribu…
