Résumé : When Henry B. Plant brought the railroad to Tampa in 1884, he opened the door for many businesses to locate and flourish here. The railroad was at the center of the city's economy. From downtown it went to Port Tampa where one could board a Plant steamship to Jamaica, Cuba, New Orleans, Bermuda or other destinations. A spur of the rail line brought the train up to the west front of the hotel so guests could depart the train and walk directly into the lobby. The Tampa Bay Hotel cost approximately 2.5 million dollars to build and $500,000 to furnish. Consisting of 511 rooms, some of which were suites of 3-7 rooms, it provided a degree of luxury never before seen in Tampa. Most of the rooms had their own baths and all had electricity and telephones. In addition, guests were surrounded by a varied collection of furniture, porcelains, Venetian-style mirrors, and sculptures gathered by Mr. and Mrs. Plant in their travels in Europe. The Tampa Bay Hotel opened in 1891 amid wide fanfare and celebration. Henry Plant's dream was now a reality. The newspapers of the day described it as "brightly illuminated, filled with sumptuous decorations, thrilling music and graced with turrets, domes and minarets towering heavenward and glistening in the sun." It was a Victorian palace. The hotel was a lively place with balls, tea parties, and organized hunts during the winter social season. It was open seasonally from December to April in the 1890's. Once a guest arrived at the hotel, he needed to be entertained. Guests went wild game hunting as well as fresh and salt-water fishing. Water sports were also included like sailing, rowing, and canoeing. For the less adventuresome, there were bicycles, carriages, and rickshaws to ride you around the property. The hotel also offered golf, tennis, shuffleboard, billiards, and even a racetrack.

Résumé : International audience
Childhood absence epilepsy is a prototypic form of generalized nonconvulsive epilepsy characterized by short impairments of consciousness concomitant with synchronous and bilateral spike-and-wave discharges in the electroencephalogram. For scientists in this field, the BS/Orl and BR/Orl mouse lines, derived from a genetic selection, constitute an original mouse model "in mirror" of absence epilepsy. The potential of MALDI imaging mass spectrometry (IMS) for the discovery of potential biomarkers is increasingly recognized. Interestingly, statistical analysis tools specifically adapted to IMS data sets and methods for the identification of detected proteins play an essential role. In this study, a new cross-classification comparative design using a combined discrete wavelet transformation-support vector machine classification was developed to discriminate spectra of brain sections of BS/Orl and BR/Orl mice. Nineteen m/z ratios were thus highlighted as potential markers with very high recognition rates (87-99%). Seven of these potential markers were identified using a top-down approach, in particular a fragment of Synapsin-I. This protein is yet suspected to be involved in epilepsy. Immunohistochemistry and Western Blot experiments confirmed the differential expression of Synapsin-I observed by IMS, thus tending to validate our approach. Functional assays are being performed to confirm the involvement of Synapsin-I in the mechanisms underlying childhood absence epilepsy.

Résumé : 1. Trade-offs among functional traits reveal major plant strategies that can give insight into species distributions and ecosystem processes. However, current identification of plant strategies lacks the integration of root structural traits together with leaf and stem traits. 2. We examined correlations among 14 traits representing leaf, stem and woody root tissues. Traits were measured on 1084 individuals representing 758 Neotropical tree species, across 13 sites representative of the environmental variation encompassed by three widespread habitats (seasonally flooded, clay terra firme and white-sand forests) at opposite ends of Amazonia (French Guiana and Peru). 3. Woody root traits were closely aligned with stem traits, but not with leaf traits. Altogether leaf, stem and woody root traits delineated two orthogonal axes of functional trade-offs: a first axis defined by leaf traits, corresponding to a leaf economics spectrum, and a second axis defined by covarying stem and woody root traits, corresponding to a wood economics spectrum. These axes remained consistent when accounting for species evolutionary history with phylogenetically independent contrasts. 4. Despite the strong species turnover across sites, the covariation among root and stem structural traits as well as their orthogonality to leaf traits were strongly consistent across habitats and regions. 5. We conclude that root structural traits mirrored stem traits rather than leaf traits in Neotropical trees. Leaf and wood traits define an integrated whole-plant strategy in lowland South American forests that may contribute to a more complete understanding of plant responses to global changes in both correlative and modelling approaches. We suggest further meta-analyses in expanded environmental and geographic zones to determine the generality of this pattern.

Résumé : Modern geochronology has moved beyond the acquisition of dates: the goal is to understand the significance of these numbers for the geodynamic evolution of Earth at all scales. The coupling of the laser-ablation microprobe (LAM) to inductively coupled plasma mass spectrometers (ICPMS, multicollector (MC)-ICPMS) has revolutionised geochronology and geochemistry over the last 10 years. These systems enable the rapid and precise in situ analysis of trace-element patterns and isotopic systems, while adding information related to microstructural context and major-element composition. The integration of these multiple sources of data is crucial in constraining the origin of the sample and the processes leading to its formation, so that we can understand the meaning of a date in terms of geological events. LAM-ICPMS measurement of U-Pb ages and trace-element patterns in zircon, coupled with LAM-MC-ICPMS analysis of Hf isotopes in the same grains, gives new insights into the processes of magma genesis. Applied to detrital zircons from modern drainages or sedimentary rocks (the TerraneChron approach), it becomes a powerful tool to investigate problems of crustal evolution on scales ranging from single terranes to continents. The in situ analysis (LAM-MC-ICPMS) of Re-Os systematics in single grains of sulfides in mantle-derived peridotites has demonstrated that most mantle rocks contain several generations of Os-bearing sulfides; whole-rock analyses are mixtures reflecting multiple melting and metasomatic events in the lithospheric mantle. These deep-seated events are commonly mirrored in the crust; Os model-age spectra from xenolith suites show age 'peaks' that correspond to the ages of thermal/tectonic events in the overlying crust, suggesting strong linkages between crust and mantle. Integrated studies of the timing and nature of crustal and mantle events, using these techniques, will be important for understanding the large-scale dynamics of the Earth.

Résumé : International audience
The Black Rat (Rattus rattus) spread out of Asia to become one of the world's worst agricultural and urban pests, and a reservoir or vector of numerous zoonotic diseases, including the devastating plague. Despite the global scale and inestimable cost of their impacts on both human livelihoods and natural ecosystems, little is known of the global genetic diversity of Black Rats, the timing and directions of their historical dispersals, and the risks associated with contemporary movements. We surveyed mitochondrial DNA of Black Rats collected across their global range as a first step towards obtaining an historical genetic perspective on this socioeconomically important group of rodents. We found a strong phylogeographic pattern with well-differentiated lineages of Black Rats native to South Asia, the Himalayan region, southern Indochina, and northern Indochina to East Asia, and a diversification that probably commenced in the early Middle Pleistocene. We also identified two other currently recognised species of Rattus as potential derivatives of a paraphyletic R.rattus. Three of the four phylogenetic lineage units within R. rattus show clear genetic signatures of major population expansion in prehistoric times, and the distribution of particular haplogroups mirrors archaeologically and historically documented patterns of human dispersal and trade. Commensalism clearly arose multiple times in R. Rattus and in widely separated geographic regions, and this may account for apparent regionalism in their associated pathogens. Our findings represent an important step towards deeper understanding the complex and influential relationship that has developed between Black Rats and humans, and invite a thorough re-examination of host-pathogen associations among Black Rats.

Résumé : International audience
Crystal growth driven by a flowing solution is modeled for a flow with low Reynolds number using a computational dynamic software. Considering equivalent crystallographic faces, the chemical flux is calculated along upstream and downstream faces. Upstream flux is higher compared to downstream and leads to a symmetry breakdown of the crystal shape and develops mirror symmetry parallel to the flow velocity. Moreover the ratio of these two fluxes (upstream / downstream) gives a quantitative relation between the relative crystal growth rate and the flow velocity. Thus, using an inverse method, the flow direction and velocity can be deduced by the study of the variation of the growth band thicknesses of equivalent crystallographic faces. This new method was applied to the formation of metasomatic tourmalinite associated with a leucogranite sill. The approach is complemented by a study of the chemistry of the tourmaline. In the studied case, the application of the new method gives the high fluid velocities in pores (10-3 - 10-4 m/s) during metasomatism. Equivalent Darcy velocities are estimated and discussed accounting for the major role played by the regional deformation. Finally, a two-stage tectono-hydrodynamic model is proposed for the metsomatism. The first stage is genetically linked to the sill injection, and the second is characterized by a wider event with hydrothermal flow passing along the leucogranite sills.

Résumé : International audience
A hybrid linear ion-trap Fourier-transform ion cyclotron resonance mass spectrometer was used for top-down characterization of the abundant human salivary Cystatins, including S, S1, S2, SA, SN, C, and D, using collisionally activated dissociation (CAD) after chromatographic purification of the native, disulfide intact proteins from saliva. Post-translational modifications and protein sequence polymorphisms arising from single nucleotide polymorphisms (SNPs) were assigned from precursor and product ion masses at a tolerance of 10 ppm allowing confident identification of individual intact mass tags. Cystatins S, S1, S2, SA and SN were cleaved of a N-terminal 20 amino-acid signal peptide, and Cystatin C a 26-residue peptide, to yield a generally conserved N-terminus. In contrast, Cystatin D isoforms with 24 and 28 amino-acid residue N-terminal truncations were found such that their N-termini were not conserved. Cystatin S1 was phosphorylated at Ser3, while S2 was phosphorylated at Ser1 and Ser3 of the mature protein, in agreement with previous work. Both Cystatin D isoforms carried the polymorphism C46R (SNP: rs1799841). The 14328 Da isoform of Cystatin SN previously assigned with polymorphism P31L due to a SNP (rs2070856) was found only in whole saliva. Parotid secretions contained no detectable Cystatins while whole saliva largely mirrored the contents of submandibular/sublingual (SMSL) secretions. Top-down high-resolution mass spectrometry is a powerful tool for the identification and characterization of potential protein biomarkers in saliva.

Résumé : On observe en martinique certains élèves qui entrent et sortent du système secondaire ne maîtrisant pas le langage écrit. cependant certains troubles du langage écrit pourraient provenir d'un manque de repères, de désordre de la « maison intérieure ». des travaux plaçant l'individu dans une perspective constructiviste ont certes déjà été menés en martinique. cependant des travaux mettant l'élève martiniquais au centre de sa culture et considérant cette dernière comme vecteur de compétences écrites et de savoir pourraient être considérés comme un nouveau champ d'investigation. d'après jérôme bruner les récits en forme l'expérience humaine.mes recherches m'amèneront à considérer deux genres de récits : les récits autobiographiques et les contes martiniquais comme des vecteurs de la culture locale et comme des compensateurs de manques au niveau des mémoires cognitives, collectives, culturelles et individuelles. ils pourraient par voie de conséquence devenir des moyens de remédiation aux problèmes liés à l'écrit. je privilégierai comme champ d'observation les adolescents en difficulté entrant en classe de sixième.
The present research deals with cultural psychology. It aims to show how culture can influence the cognitive skills of underachieving students.Before cultural psychology emerged, social constructivism best represented by Piaget and Vygotski, and later in the twentieth century by Jérôme Bruner or Bertrand Troadec underlined the importance of culture in children’s mental dispositions.Their research on influence of culture in children’s cognitive dispositions are used as guiding principle.Over the years, it has been noticed that quite a large number of Martinican secondary school students from ages 11 to 12 had writing problems. In reality, national assessments have always confirmed this fact. Obviously papers about children’s writing problems have been written by many specialists. But it is interesting to consider this issue in relation to cultural psychology. In addition, this perspective shows the subject in his own singularity in interaction with his social background. It appears that stories, presented as social background’s products, are considered as systems which make sense for students who are in cognitive distress. Skills in writting will thus become for us a kind of mirror to assess the quality of thinking.
