Convergent Morphological Evolution in Silene Sect. Italicae (Caryophyllaceae) in the Mediterranean Basin
2022
Recent divergence can obscure species boundaries among closely related taxa. Silene section Italicae (Caryophyllaceae) has been taxonomically controversial, with about 30 species described. We investigate species delimitation within this section using 500 specimens sequenced for one nuclear and two plastid markers. Despite the use of a small number of genes, the large number of sequenced samples allowed confident delimitation of 50% of the species. The delimitation of other species (e.g., Silene nemoralis, S. nodulosa and S. andryalifolia) was more challenging. We confirmed that seven of the ten chasmophyte species in the section are not related to each other but are, instead, genetically c…
Voluntary Imitation in Alzheimer’s Disease Patients
2016
International audience; Although Alzheimer's disease (AD) primarily manifests as cognitive deficits, the implicit sensorimotor processes that underlie social interactions, such as automatic imitation, seem to be preserved in mild and moderate stages of the disease, as is the ability to communicate with other persons. Nevertheless, when AD patients face more challenging tasks, which do not rely on automatic processes but on explicit voluntary mechanisms and require the patient to pay attention to external events, the cognitive deficits resulting from the disease might negatively affect patients' behavior. The aim of the present study was to investigate whether voluntary motor imitation, i.e.…
On Equal Terms? : On Implementing Infants’ Cultural Rights
2020
How can we implement infants’ cultural rights? Is there even reason to confer such rights to non-speaking children, or is it enough that we recognise slightly older children as culturally active individuals? Acknowledging children’s intellectual capacities and their right to be heard in matters that concern them are important threads in research on children and ideals of childrearing during the last hundred years. This development is parallel with the one leading from the Declaration of the Rights of the Child in 1923 to the UN Convention on the Rights of the Child in 1989. The spirit of human rights that informs these documents cannot be underestimated. Yet reading the Convention carefully…
Más allá de Marx: postobrerismo y posmarxismo. Una revisión de los fundamentos teóricos de la multitud y el pueblo
2018
The article is a synthetic essay that exposes the main theoretical lines of the postmarxist approach of Laclau and Mouffe, on the one hand, and the autonomist post-operaism of Negri, Hardt, Virno, etc., on the other hand. These theories are conceived as attempts to rationalize current political bets by various political sectors and social movements. It analyzes both argumentative strategies from «orthodox» Marxism and the structure / superstructure relationship; and the forms of constitution of new subjectivities. It compares the theoretical fundamentals of hegemonic articulations and counter-power experiences. It discusses, likewise, the scope and limitations of the categories of «people» …
Accumulation of disparity in physical activity in old age
2012
Background and aims: The level of physical activity often declines in old age, although many older people would like to be more active than what they are capable of. This leads to unmet physical activity need, the feeling that one’s level of physical activity is inadequate, which is a manifestation of disparity in physical activity in old age. The accumulation of risk factors, including mobility limitations, low socioeconomic status (SES) and lack of social support may increase disparity in physical activity. The aim of this study was to investigate how the accumulation of risk factors is associated with unmet physical activity need in older community-living people. Methods: The study was b…
Molecular phylogeny of the genus Chondrina (Gastropoda, Panpulmonata, Chondrinidae) in the Iberian Peninsula
2022
[EN] Chondrina Reichenbach, 1828 is a highly diverse genus of terrestrial molluscs currently including 44 species with about 28 subspecific taxa. It is distributed through North Africa, central and southern Europe, from Portugal in the West to the Caucasus and Asia Minor in the East. Approximately 70% of the species are endemic to the Iberian Peninsula constituting its main center of speciation with 34 species. This genus includes many micro endemic taxa, some of them not yet described, confined to limestone habitats (being strictly rock-dwelling species). They are distributed on rocky outcrops up to 2000 m.a.s.l. It is a genus of conical-fusiform snails that differ mainly in shell characte…
« Le problème de la délimitation des concepts psychologiques chez Wittgenstein »
2010
International audience; la philosophie peut être décrite comme un travail de cartographie conceptuelle. Mais cela implique-t-il que les frontières entre les concepts en question sont parfaitement définies ? Non, répond Wittgenstein. On examine la portée de cette thèse sur un cas à la fois particulier et essentiel : celui des concepts dit ‘psychologiques’.
Taxonomy and evolution of the Convolvulus sabatius complex (Convolvulaceae)
2010
A revision of the Convolvulus sabatius complex is presented and five taxa are now recognised. Convolvulus valentinus is re-circumscribed to comprise only blue-flowered individuals. Yellow-flowered plants previously referred to this species are transferred to C. supinus where they are recognised as a distinct variety: C. supinus var. melliflorus, comb nov. Variation in intensity of flower colour, pubescence and leaf shape among blue-flowered C. valentinus is highly variable within populations and in contrast to earlier treatments, no infraspecific taxa based on these traits are recognised. Despite suggestions to the contrary, the delimitation of the cultivated ornamental C. sabatius and its …
Musculoskeletal pain and use of analgesics in relation to mobility limitation among community-dwelling persons aged 75 years and older
2012
Pain and factors related to it constitute serious health problems in the older population. This populationbased cross-sectional study aimed to investigate whether musculoskeletal pain is associated with mobility limitation and whether the relationship between pain and mobility limitation varies according to the use of analgesics among community-dwelling older people. A total of 622 community-dwelling participants aged 75 years and older (mean age 80.4, 74% women) were interviewed about presence and severity of musculoskeletal pain. Self-reported analgesic drug utilization was verified against medical records. Mobility limitation was assessed by the Timed Up & Go test (TUG) time of >13.5 s o…
