The objective of this technical note is to explore the applicability of a newly introduced nonlinear system identification technique to spacecraft structures. To this end, numerical experiments are conducted using a finite element model of the SmallSat spacecraft. A detailed introduction to the method, referred to as the frequency-domain nonlinear subspace identification (FNSI) method, is provided and its major assets are commented. Random-type and sine-sweep excitations are considered and identification results are extensively discussed. [less ▲]

Characterizing population genetic structure using phylogeographic approach contributes to understanding of evolutionary processes that affect plant populations. The present study investigated how past environmental variations can shape the spatial genetic diversity of an African timber tree species, Milicia excelsa (Welw) C.C. Berg. Given that plant responses to disturbances are closely linked to life history traits, this research also aimed to describe relationships between the reproductive traits of M. excelsa and its population genetic structure. Phylogeographic analyses were performed throughout the range of M. excelsa using nuclear and chloroplastic markers. Ecological characterization was conducted for a single population located in south-East Cameroon. Since M. excelsa is similar to the other species of its genus, M. regia (A. Chev) C.C. Berg, we first performed a morphogenetic comparison of these two taxa. The results confirmed an important morphological similarity between the two species with very rare discriminating criteria. In fact Bayesian assignment methods and reproductive isolation patterns suggest the occurrence of interspecific hybridization, which appeared to be unidirectional: hybrids displayed the M. regia morphotype. Because M. regia is known to be more adapted to humid tropical forests, one may expect it to occur in the Congo basin zone. However, its range is restricted to the western part of West Africa while M. excelsa occurs from Guinea-Conakry to Zimbabwe. Interestingly, in the case of M. excelsa, Central and West African specimens had no shared haplotype. This result was unexpected because long gene dispersal distances were found in Cameroonian populations, as expected from the behaviours of the main dispersal animals we identified, the bat Eidolon helvum and the parrots Psittacus erithacus and Agapornis swindernianus. In general, despite the likelihood for long distance seed dispersal, distinct genetic clusters were identified over West and Central Africa and their location may support the forest refugia hypothesis. In addition a phylogeographical signal was detected in chloroplast DNA indicating a prolonged separation between West and Central Africa populations with an accumulation of new mutations. At a smaller spatial scale, patterns of genetic structure also seemed to be weakly influenced by divergent reproduction times among sympatric individuals. The level of genetic diversity in the study populations falls within the range of values calculated for other tropical tree species. If phylogeography helps to infer population history, it also requires ecological or biological information to confirm some uncertainties. Such detailed data were often lacking to completely interpret numerous of our results. The present study raised new questions and led to new perspectives for further investigation both in phylogeography and botany. [less ▲]

François Jacqmin compte parmi les quelques deux ou trois plus grands poètes de Belgique. Toute l’écriture de celui qui a dit « la poésie sera consolatrice, ou rien » est une lutte contre les limites ou les illusions de la pensée et de la parole, une tentative de dépasser l’impuissance de la poésie à conserver trace de l’émerveillement de l’homme devant la nature. Réel et langage, désir et nihilisme sont les pôles d’une œuvre capitale. [less ▲]

In 1884 Willem Kloos and Albert Verwey started work on Julia, a collection of forty poems written in the manner of the successful author Fiore della Neve (M.G.L. van Loghem). In their pamphlet The Incompetence of the Dutch Literary Critics (1886), in which Julia’s true authorship was revealed, Kloos and Verwey made plain that the poems had been conceived as deliberate nonsense, something the Dutch literary establishment had failed to recognize. Nevertheless, a close reading of the collection brings to light a number of textual similarities with Kloos’s and Verwey’s serious poetry written in the period 1883-1885. This article reveals Julia as a fascinating hybrid in which an older aesthetic coexists with a new poetical language associated with the Eighties Movement. [less ▲]

This paper is a tentative assessment of the Rawls-Machiavelli program by Philippe Van Paris, who proposes that justice is the main goal of political action (in a Rawlsian perspective) and democracy is only instrumental (the Machiavellian part of the program). The paper adresses three questions to the proposal of Philippe Van Paris : 1) Can democracy be properly defined without a condition of public debate ? 2) Don't "realistic politics" underestimate the margin of possibility we have to change "what people are" and 3) If people overemphasize that part of their interests which is linked to their ethno-national belonging, is it not because alternative political offer is not differentiated enough ?

Depuis 2003, l'Amérique latine connaît une période économique de croissance importante. Elle parvient à traverser la crise mondiale sans trop de difficultés. La demande chinoise des matières premières latino-américaines combinée à une augmentation de la consommation interne et de l'investissement expliquent ces performances. Par ailleurs, des progrès ont été accompli en matière sociale. En outre, la région connaît une stabilité politique grâce à l'enracinement de la démocratie depuis plus de 20 ans. Toutefois, l'Amérique latine a encore pas mal de défis à relever: diversification économique et des débouchés; réduction des inégalités; lutte contre la criminalité organisée, la violence et la corruption.
