A multidisciplinary analytical framework to delineate spawning areas and quantify larval dispersal in coastal fish
2019
International audience; Assessing larval dispersal is essential to understand the structure and dynamics of marine populations. However, knowledge about early-life dispersal is sparse, and so is our understanding of the spawning process, perhaps the most obscure component of biphasic life cycles. Indeed, the poorly known species-specific spawning modality and early-life traits, along with the high spatio-temporal variability of the oceanic circulation experienced during larval drift, hamper our ability to properly appraise the realized connectivity of coastal fishes. Here, we propose an analytical framework which combines Lagrangian modeling, network theory, otolith analyses and biogeograph…
Renal Programming by Transient Postnatal Overfeeding: The Role of Senescence Pathways
2020
Background: Early nutrition influences the risk of Chronic Kidney Diseases development in adulthood. Mechanisms underlying the early programming of altered renal function remain incompletely understood. This study aims at characterizing the role of cell senescence pathways in early programming of Chronic Kidney Disease after transient postnatal overfeeding. Material and Methods: Reduced litters of 3 mice pups and standard litters of 10 mice pups were obtained to induce overfed animals during lactation and control animals, respectively. Animals were sacrificed at 24 days (weaning) or at 7 months of life (adulthood). Body weight, blood pressure, kidney weight, and glomerular count were assess…
Early life body mass trajectories and mortality in older age: Findings from the Helsinki Birth Cohort Study
2014
Overweight and obesity in childhood have been linked to an increased risk of adult mortality, but evidence is still scarce.We identified trajectories of body mass index (BMI) development in early life and investigated their mortality risk. Data come from the Helsinki Birth Cohort Study, in which 4943 individuals, born 1934-1944, had serial measures of weight and height from birth to 11 years extracted from health care records, weight and height data in adulthood, and register-based mortality data for 2000-2010.Three early BMI trajectories (increasing, average, and average-to-low for men and increasing, average, and low-to-high BMI for women) were identified. Women with an increasing or low-…
La Grammaire de Condillac face au paradoxe de l'origine naturelle du langage
2012
The recent discovery of mirror neurons has rivived the gestural-imitative theory of the origin of language advocated by Condillac in the XVIIIth century. Condillac develops this theory in two stages: in the Essai (1746) he proposes a gestural theory based on the arbitrariness of the sign, while in the Grammaire (1775) he refuses arbitrariness and accepts the theory of analogy and natural imitation proposed by Charles de Brosses (1765). This choice depends on the fact that in Rousseau (1755) and Beauzee (1765) arbitrariness, as a "paradox of the original contract", now plays the role of key argument in favor of the divine origin of language. So, the theory of analogy and natural imitation is…
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.
Cultivable microorganisms associated with honeys of different geographical and botanical origin
2014
In this study, the composition of the cultivable microbial populations of 38 nectar honey and honeydew honey samples of different botanical and geographical origin were assessed. After growth in specific media, various colonies with different appearance were isolated and purified before phenotypic (morphological, physiological and biochemical traits) and genotypic [randomly amplified polymorphic DNA (RAPD), repetitive DNA elements-PCR (rep-PCR) and restriction fragment length polymorphism (RFLP)] differentiation. The identification was carried out by 16S rRNA gene sequencing for bacteria and, in addition to RFLP, by sequencing the D1/D2 region of the 26S rRNA gene for yeasts and the 5.8S-IT…
On the role of internationalization of firm-level corporate governance: The case of audit committees
2022
Research Question/IssueMotivated by the agency theory and the findings of linguistic studies, we analyze the association between the internationalization of a firm's audit committee and its corporate governance.Research Findings/InsightsBased on data from 2159 publicly traded European firms from 15 countries for the period 2000–2018, we find that firms with foreign directors on their audit committees are associated with lower financial reporting quality. The association is mitigated by stronger country-level investor protection and a higher similarity among intra-committee languages. We further find that foreign directors on the audit committee are related to stock prices being less informa…
Ancient human genomes suggest three ancestral populations for present-day Europeans
2014
We sequenced the genomes of a ∼7,000-year-old farmer from Germany and eight ∼8,000-year-old hunter-gatherers from Luxembourg and Sweden. We analysed these and other ancient genomes1,2,3,4 with 2,345 contemporary humans to show that most present-day Europeans derive from at least three highly differentiated populations: west European hunter-gatherers, who contributed ancestry to all Europeans but not to Near Easterners; ancient north Eurasians related to Upper Palaeolithic Siberians3, who contributed to both Europeans and Near Easterners; and early European farmers, who were mainly of Near Eastern origin but also harboured west European hunter-gatherer related ancestry. We model these popula…
The legal origin of income inequality
2014
The legal origin movement is implicitly functionalist, while it explicitly prioritizes economic dimensions of development. From this perspective, the empirical findings presented in this paper seem to uncover the existence of a paradox. On the one hand, common law countries are apparently characterized by countless advantages, yet they do not grow faster than civil law countries. On the other hand, common law countries present a more unequal distribution of income, thus suggesting that also from a static perspective there is no a priori reason to prefer a common law system. To further investigate this paradox, we analyze if common law countries are at least characterized by a better kind (e…
Subalternità e filosofia della storia. Appunti sul carteggio Marx-Zasulič
2021
this article proposes, through the Gramscian political-pedagogical category of subalternity, a reading of the brief exchange of letters at the beginning of 1881 between Karl Marx and Vera Zasulič, a russian revolutionary militant at that time member of the populist group Čërnyj peredel (black repartition), on an issue of great importance for the russian socialist movement: the obščina, or that specific form of common ownership of land by russian peasants. to this end, it is necessary to analyze the chapter XXiV of the first book of Capital, in which Marx outlines the historical genesis of capitalism in Western europe and, in particular, in england, through the phenomenon of «the so-called o…
