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.

When brought up before the Captain and myself they both confessed their guilt. Nobibux stated that for the last ten years he had allowed men to commit acts of beastliness: he had no doubt induced Mohangu to do this criminal act. Nobibux was put in irons and Mohangu, after blistering his penis, was made to holystone [scrub the decks] from 6 a.m. to 6 p.m. daily." [latitude 35.17 s. and longitude 22.10 e.] [nobibux handcuffed every night from sept 25 to landing on oct 31, as was a man who had jumped overboard and was rescued] criminal charges brought against two immigrants; in CO marginalia, discussion over the legality of the punishment and doubt expressed over whether there was any sodomy committed at all; indication there wasn't enough proof to prosecute: "the men should have been put in confinement and tried in British Guiana for an offense committed on the high seas on board a British vessel..."; fine the surgeon but should he be barred from re-employment? inspector general of police investigated; attorney general decided not to prosecute; IAG criticizes SS for punishing the two without fully and carefully enquiring into the case. violated Rule 165 relating to colonial emigration, which strictly prohibits harsh treatment of the people The contract with the surgeon superintendant enclosed shows that each was granted a pint of wine per day and stout. This surgeon was given 20 shillings per immigrant landed alive. for immigrants classified as invalids on embarking, if they died during voyage, he received a pro-rated amount, based on how long they lived; wife not allowed to go along. Arthur Harrison, SS, states on November 4, 1898: [on 25th Sept, when near the Cape of Good Hope, his compounder Abdul Wahed reported to him at 8 a.m. that he heard two men had committed sodomy during the night. he told the compounder to take the men to the hospital, where he would question them.] [witness, the sirdar Rambuccus, brought in with the two men. questioned in front of them, he said that he was on watch in between decks at midnight and "saw something unusual between these two men, they being under one blanket; he pulled off the blanket and saw them committing sodomy." he called the head sirdar at once. the prisoners denied it to the head sirdar but then later confessed. they were left in the charge of the hear sirdar for the rest of the night. captain also present at inquiry. while Rambuccus was giving this testimony, neither prisoner said anything.] [the head sirdar Salikram is then questioned. confirms being called as above. says he separated the men and "asked them why they were doing this wrong thing, that they at first denied it and afterwards they confessed they did it for pleasure."] [when questioned by SS, men at once confessed. Nabibux: "I have done it." Mohungu said same, "as far as I can remember. I cannot remember the words they used in confessing." Nabibux placed in irons fastened to a stanchion in the hospital. Mohangu placed in hospital and ordered to holystone from 6 a.m to 6 p.m. "I blistered the penis of Mohungu. I did so as a punishment as I thought he deserved it." did this right after enquiry concluded. the captain knew Harrison did this. "Mohungu was the man who committed the act on Nabibuccus. I blistered him as a preventitive, as he might have attempted the act again. I have known cases where the penis has been blistered as a preventitive treatment, in case of masturbation with boys."] [says he didn't see it as a crime committed against the laws of England, but "as a matter of discipline on board ship"; didn't examine their private parts for evidence] "Since this all occurred, it has come to my knowlegde that the head sirdar had threatend the two men to make them confess. Since I heard this, I have questioned them. Both denied the act and said Salikram had threatened to make them confess. My compounder's name is Abdul Wahed. I have heard from him since that the man Rambuccus who caught them had a spite against one of the men, owing to something that had occurred in the country Depot in India." ABDUL WAHED, THE CHIEF COMPOUNDER, STATES: [the inquiry occurred at about 8:30 p.m. on the 25th Sept.] "I heard Mohungu say he had put his penis in Nabibux' anus, and some days afterwards both men said to me that Rambux and Salikram had threatened to beat them throughout the voyage if they did not confess to having committed the sodomy." "Nabibux told me that he and Rambux had had a row in the Fizabad depot and he told me that Rambux had a spite against him." [the prisoners were under his charge in the hospital] [doesn't know what the depot quarrel was about. didn't ask. never noticed any ill feeling between Rambux and any of the men before this happened. never noticed Mohangu and Nabibux to be much in each other's company] RAMBUCCUS [an Ahir. says he knew Nabibuccus for a month in the Fyzabad depot, where he was a sirdar] "The men were under a platform sleeping. There were other coolies sleeping there too. The men were sleeping in their usual place... I noticed two men under one blanket. I have orders not to allow this, so I hauled the blanket off. Mohangu was on top of Nabibux who was lying on his back. Mahangu was lying on his stomach. I asked them what they were doing. They gave no reply. Mahangu came off. I did not see his private parts. His baba was loose. I did not notice the state of Nabibux' baba. He had it on, but I don't know whether the crupper of the baba was undone or not. I did not see his private parts. I did not see his anus. I did not see Mahungu's penis in Nabibux' anus, but from their position I suspected that they were committing sodomy... These two men always slept together during the voyage." SALIKRAM "They said Rambux hauled the blanket and shook them up while they were asleep. Rambuccus said they were committing sodomy but I don't think they were. They appeared to me just as if they had just been awakened. Their eyes seemed heavy with sleep." "I never knew either of these men before I met them onboard. Myself and Rambuccus do not agree. I never noticed Rambuccus and either of the two men have any quarrel. I never noticed Nabibux and Monungu keeping much company. I don't know whether these men were in the habit of sleeping alongside of one another. I never threatened these men to make them confess. I never heard the men confess they had done it. They did not confess before me." IN THE END: 50 pounds deducted from Harrison's gratuity for inflicting corporal punishment

Résumé : International audience
Peridotite xenoliths exhumed by Quaternary alkaline magmatism in the Tahalgha district, southern Hoggar, represent fragments of the subcontinental lithospheric mantle beneath the boundary between the two major structural domains of the Tuareg Shield: the ‘Polycyclic Central Hoggar’ to the east and the ‘Western Hoggar’, or ‘Pharusian Belt’, to the west. Samples were collected from volcanic centres located on both sides of a major lithospheric shear zone at 4°35' separating these two domains. Although showing substantial variations in their deformation microstructures, equilibrium temperatures and modal and chemical compositions, the studied samples do not display any systematic changes of these features across the 4°35' fault. The observed variations rather record small-scale heterogeneities distributed throughout the study area and reflecting the widespread occurrence of vein conduits and metasomatized wall-rocks related to trans-lithospheric melt circulation during the Cenozoic. These features include partial annealing of pre-existing deformation microstructures, post-deformation metasomatic reactions, and trace-element enrichment, coupled with heating from 750–900°C (low-temperature lherzolites) to 900–1150°C (intermediate-T lherzolites and high-T harzburgites and wehrlites). Trace-element modelling confirms that the range of rare earth element (REE) variations observed in the Tahalgha clinopyroxenes may be accounted for by reactive porous flow involving a single stage of basaltic melt infiltration into a light REE (LREE)-depleted protolith. Whole-rock compositions record the final entrapment of disequilibrium metasomatic melts upon thermal relaxation of the veins–wall-rock system. The striking correlations between equilibrium temperatures and trace-element enrichment favor a scenario in which the high-temperature peridotites record advective heat transport along melt conduits, whereas the intermediate- and low-temperature lherzolites reflect conductive heating of the host Mechanical Boundary Layer. This indicates that the lithosphere did not reach thermal equilibrium, suggesting that the inferred heating event was transient and was rapidly erased by thermal relaxation down to the relatively low-temperature present-day geotherm. The low-T (<900°C) deformed lherzolites (porphyroclastic to equigranular) are characterized by only incipient annealing and LREE-depleted clinopyroxene compositions. They were only weakly affected by the Cenozoic events and could represent relatively well-preserved samples from rejuvenated Pan-African lithosphere. Extensive lithospheric rejuvenation occurred either regionally during the Pan-African orogeny, as a result of lithospheric delamination or thermomechanical erosion after thickening, or more locally along the meridional shear zones. The low-T Tahalgha lherzolites are comparable with lherzolites from Etang de Lherz, southern France, interpreted as lithospheric mantle rejuvenated by melt-induced refertilization during a late stage of the Variscan orogeny.

Résumé : International audience
Accessory phases are important hosts of trace elements; allanite may contain >90% of the REE in a bulk rock. The mobility and redistribution of several trace elements, notably HREE, Th, U, and Y is thus controlled by reactions involving allanite and other REE phases, as well as several rock-forming minerals. As these elements are commonly concentrated in mature elastic sediments, a suite of impure quartzite was studied. Two eclogite facies samples from the Monometamorphic Cover Complex of the Sesia Zone (Western Italian Alps) are presented in some detail, as they reveal a remarkably rich spectrum of reaction relationships that involve REE phases.;Two allanite-forming reactions were inferred from textures and phase compositions;(1) monazite + Ca-silicate(?) + fluid -> allanite + apatite + thorite;;(2) monazite + thorite + Ca-silicate(?) + fluid -> Th-rich allanite + auerlite +/- apatite.;Petrographic observations and thermodynamic models suggest that allanite entered the HP assemblage at similar to 530 degrees C and 17-18 kbar during prograde metamorphism.;In one sample, allanite is rimmed by epidote rich in Y and HREE that grew at the expense of xenotime. Two net transfer reactions were derived;(3) xenotime + allanite + fluid -> Y-rich epidote + apatite + thorite;;(4) xenotime + allanite + fluid -> Y-rich epidote + aeschynite + thorite + (phosphate?).;Textural relationships and trace element analyses of coexisting allanite/monazite and xenotime/Y-rich epidote reveal systematic partitioning of the REE. Partition coefficients for the HREE are compatible with equilibrium fractionation, whereas those for the LREE show patterns that seem to be inherited from the precursor phases, in this case zircon with variable LREE composition.

The Caribe Hilton was built in 1949, becoming the first Hilton hotel outside of the continental US, and thus marking the beginning of Hilton International. Designed by Osvaldo Toro and Miguel Ferrer, it originally contained 300 rooms, but has since expanded through multiple renovations (including major remodeling and grand re-opening in 1999). A staple of the Puerto Rican tourism industry, The Caribe Hilton’s frequent guests include famous entertainers, athletes, and political figures. It is also known for one of its bars, where the first Piña Colada drink was made in August 1954. Also visible in the photograph, is part of the Condado Lagoon and the historic Fortín de San Gerónimo del Boquerón, which was built in the 17th century and was crucial in the defense of San Juan against a British attack in 1797.

Résumé : We report rare earth element (REE) and neodymium (Nd) isotope data for the organic fraction of sediments collected from various depositional environments, i.e. rivers (n=25), estuaries (n=18), open-ocean settings (n=15), and cold seeps (n=12). Sedimentary Organic Matter (SOM) was extracted using a mixed hydrogen peroxide/nitric acid solution (20%-H2O2 – 0.02M-HNO3), after removal of carbonate and oxy-hydroxide phases with dilute hydrochloric acid (0.25M-HCl). A series of experimental tests indicate that extraction of sedimentary organic compounds using H202 may be complicated occasionally by partial dissolution of sulphide minerals and residual carbonates. However, this contamination is expected to be minor for REE because measured concentrations in H2O2 leachates are about two-orders of magnitude higher than in the above mentioned phases. The mean REE concentrations determined in the H2O2 leachates for samples from rivers, estuaries, coastal seas and open-ocean settings yield relatively similar levels, with ΣREE = 109 ± 86 ppm (mean ± s; n=58). The organic fractions leached from cold seep sediments display even higher concentration levels (285 ± 150 ppm; mean ± s; n=12). The H2O2 leachates for most sediments exhibit remarkably similar shale-normalized REE patterns, all characterized by a mid-REE enrichment compared to the other REE. This suggests that the distribution of REE in leached sedimentary organic phases is controlled primarily by biogeochemical processes, rather than by the composition of the source from which they derive (e.g. pore, river or sea- water). The Nd isotopic compositions for organic phases leached from river sediments are very similar to those for the corresponding detrital fractions. In contrast, the SOM extracted from marine sediments display εNd values that typically range between the εNd signatures for terrestrial organic matter (inferred from the analysis of the sedimentary detrital fractions) and marine organic matter (inferred from the analysis of local surface seawater). A notable exception is the case of organic matter (OM) fractions leached from cold seep sediment samples, which sometimes exhibit εNd values markedly different from both terrigenous and surface seawater signatures. This suggests that a significant fraction of organic compounds in these sediments may be derived from chemosynthetic processes, recycling pore water REE characterized by a distinct isotopic composition. Overall, our results confirm that organic matter probably plays an important role in the oceanic REE budget, through direct scavenging and remineralization within the water column. Both the high REE abundances and the shape of shale-normalized patterns for leached SOM also suggest that OM degradation in sub-surface marine sediments during early diagenesis could control, to a large extent, the distribution of REE in pore waters. Benthic fluxes of organic-bound REE could hence substantially contribute to the exchange processes between particulates and seawater that take place at ocean margins. Neodymium isotopes could provide useful information for tracing the origin (terrestrial versus marine) and geographical provenance of organic matter, with potential applications in paleoceanography. In particular, future studies should further investigate the potential of Nd isotopes in organic compounds preserved in sedimentary records for reconstructing past variations of surface ocean circulation.

Résumé : For many trace elements, continental margins are the location of intense exchange processes between sediment and seawater, which control their distribution in the water column, but have yet to be fully understood. In this study, we have investigated the impact of fluid seepage at cold seeps on the marine cycle of neodymium. We determined dissolved and total dissolvable (TD) concentrations for REE and well-established tracers of fluid seepage (CH4, TDFe, TDMn), and Nd isotopic compositions in seawater samples collected above cold seeps and a reference site (i.e. away from any fluid venting area) from the Niger Delta margin. We also analyzed cold seep authigenic phases and various core-top sediment fractions (pore water, detrital component, easily leachable phases, uncleaned foraminifera) recovered near the hydrocast stations. Methane, TDFe and TDMn concentrations clearly indicate active fluid venting at the studied seeps, with plumes rising up to about 100 m above the seafloor. Depth profiles show pronounced REE enrichments in the non-filtered samples (TD concentrations) within plumes, whereas filtered samples (dissolved concentrations) exhibit slight REE depletion in plumes relative to the overlying water column and display typical seawater REE patterns. These results suggest that the net flux of REE emitted into seawater at cold seeps is controlled by the presence of particulate phases, most probably Fe-Mn oxyhydroxides associated to resuspended sediments. At the reference site, however, our data reveal significant enrichment for dissolved REE in bottom waters, that clearly relates to diffusive benthic fluxes from surface sediments. Neodymium isotopic ratios measured in the water column range from epsilon(Nd) similar to-15.7 to -10.4. Evidence that the epsilon(Nd) values for Antarctic Intermediate waters (AAIW) differed from those reported for the same water mass at open ocean settings shows that sediment/water interactions take place in the Gulf of Guinea. At each site, however, the bottom water epsilon(Nd) signature generally differs from that for cold seep minerals, easily leachable sediment phases, and detrital fractions from local sediments, ruling out the possibility that seepage of methane-rich fluids and sediment dissolution act as a substantial source of dissolved Nd to seawater in the Gulf of Guinea. Taken together, our data hence suggest that co-precipitation of Fe-Mn oxyhydroxide phases in sub-surface sediments leads to quantitative scavenging of dissolved REE at cold seeps, preventing their emission into bottom waters. Most probably, it is likely that diffusion from suboxic surface sediments dominates the exchange processes affecting the marine Nd cycle at the Niger Delta margin. (C) 2011 Elsevier B.V.

Résumé : The activity of the Damavand volcano (Central Alborz, northern Iran) began 1.8 Ma ago and continued up to 7 ka BP. Although the volcanic suite is clearly of shoshonitic affinity, only two petrographic types can be distinguished in the studied lavas: (1) weakly differentiated absarokites (49 < %SiO2 < 51), scattered around the volcano but with a regional extension, (2) highly differentiated banakites (59 < %SiO2 < 63), which form the bulk of the 4,000 m thick volcanic pile. All lavas are alkalic (3.7 < %K2O < 5), REE and LILE-rich (e.g., 85 < La < 148 ppm; 9 < Th < 32 ppm) and show highly fractionated REE patterns (69 < La/Yb < 115) and pronounced Nb-Ta negative anomalies. The absarokites are characterised by Sr (0.7045-0.7046) and Nd (0.51266-0.51269) isotope compositions close to the Bulk Earth values, and distinct from those of the banakites (0.7047 < Sr-87/Sr-86 < 0.7049, 0.51258 < Nd-143/Nd-144 < 0.51262). The Pb isotope ratios are also slightly lower in the absarokites than in the banakites (18.71 < Pb-206/Pb-204 < 18.77, 15.62 < Pb-207/Pb-204 < 15.63, 38.85 < Pb-208/Pb-204 < 38.91, and 18.77 < Pb-206/Pb-204 < 18.84, 15.62 < Pb-207/Pb-204 < 15.64, 38.94 < Pb-208/Pb-204 < 39.06, respectively). Overall, there is a clear tendency towards higher Sr, Pb and lower Nd isotope ratios with increasing degree of differentiation. This study suggests that the absarokites result from a low degree of partial melting (similar to 5%) of a highly metasomatized mantle source, which inherited its characteristics from an old subduction setting. The initiation of volcanic activity 1.8 Ma ago results from variations in the lithospheric thermal regime, probably related to lithospheric delamination as proposed for Anatolia (Pearce et al. 1990). The banakites are mainly generated by extensive fractional crystallisation (similar to 70%) of the absarokitic magma, with a limited amount (a few percents) of assimilation of an old crustal component, in the form of bulk assimilation or AFC processes, which both can explain the Sr, Nd and Pb isotope data.

Description : Cette thèse propose une lecture critique de l'oeuvre narrative de l'écrivaine guadeloupéenne Maryse Condé, du point de vue esthétique (poétique) et idéologique (politique). À partir de la notion plurielle de « différence » en tant qu'unique singularité identitaire en (re)construction, l'auteure entreprend dans ce travail l'exégèse esthétique et idéologique des ouvrages narratifs publiés par Maryse Condé depuis ses débuts. Par ailleurs, l'auteure montre les rapports de sororité entre l'oeuvre condéenne et celles de la guadeloupéenne Gisèle Pineau, d'une part; et des martiniquaises Simone Schwarz-Bart, Françoise Ega, Michèle Maillet et Suzanne Dracius-Pinalie, d'autre part.

Résumé : International audience
We report trace element concentrations of silicate phases in chondrules from LL3 ordinary chondrites Bishunpur and Semarkona. Results are similar to previously reported data for carbonaceous chondrites, with rare earth element (REE) concentrations increasing in the sequence olivine < pyroxene < mesostasis, and heavy REE (HREE) being enriched by 1–2 orders of magnitude (CI-normalized) relative to light REE (LREE) in ferromagnesian silicates, although no single olivine with very large LREE/HREE fractionation has been found. On average, olivine in type II chondrules is poorer in refractory lithophile incompatible elements (such as REE) than its type I counterpart by a factor of ∼2. This suggests that olivine in type I and II chondrules formed by batch and fractional crystallization, respectively, implying that type II chondrules formed under faster cooling rates (>∼10 K/h) than type I chondrules. Appreciable Na concentrations (3–221 ppm) are measured in olivine from both chondrule types; type II chondrules seem to have behaved as closed systems, which may require chondrule formation in the vicinity of protoplanets or planetesimals. At any rate, higher solid concentrations in type II chondrule forming regions may explain the higher oxygen fugacities they record compared to type I chondrules. Type I and type II chondrules formed in different environments and the correlation between high solid concentrations and/or oxygen fugacities with rapid cooling rates is a key constraint that chondrule formation models must account for.

Résumé : International audience
It is now well recognized that information management systems often deal with geographic information even if they often do not take advantage of it. In these systems, requirements engineering (RE) is becoming more and more important in helping stakeholders to model their requirements regarding the quality of the data.However, to date, few RE projects take geographic information and geographic constraints into account. We thus propose to study in this paper the question of managing such geographic constraints in the framework of RE. We propose an extension of the RE model and its implementation within the KAOS framework, and the use of geographic ontologies

Résumé : At least six virus diseases are presently known in cultured penaeid shrimp. Each of these six penaeid virus diseases (BP = Baculovirus penaei ; MBV = Penaeus monodon -type baculovirus (including PBV of Australian penaeids); BMN = baculoviral midgut gland necrosis; HPV = hepatopancreatic parvo-like virus; IHHNV = infectious hypodermal and hematopoietic necrosis virus; and REO = reo-like virus of the hepatopancreas) may be comprised by a multitude of individual strains, some of which are highly pathogenic to some penaeids, while being of little importance to others.

Résumé : If the net flux to the island arc crust is primitive arc basalt, the evolved composition of most arc magmas entails the formation of complementary thick ultramafic keels at the root of the island arc crust. Dunite, wehrlite, and Cr-rich pyroxenite from the Jijal complex, constituting the Moho transition zone of the Kohistan paleo–island arc (northern Pakistan), are often mentioned as an example of high-pressure cumulates formed by intracrustal fractionation of mantle-derived melts, which were later extracted to form the overlying mafic crust. Here we show that calculated liquids for Jijal pyroxenites-wehrlites are strongly rare earth element (REE) depleted and display flat or convex-upward REE patterns. These patterns are typical of boninites and are therefore unlike those of the overlying mafic crust that have higher REE concentrations and are derived from light rare earth element (LREE)–enriched melts similar to island arc basalt. This observation, along with the lower 208Pb/204Pb and 206Pb/204Pb ratios of Jijal pyroxenites-wehrlites relative to gabbros, rejects the hypothesis that gabbros and ultramafic rocks derive from a common melt via crystal fractionation. In the 208Pb/204Pb versus 206Pb/204Pb diagram, ultramafic rocks and gabbros lie on the same positive correlation, suggesting that their sources share a common enriched mantle 2 (EM2) signature but with a major depleted component contribution for the ultramafic rocks. These data are consistent with a scenario whereby the Jijal ultramafic section represents a Moho transition zone formed via melt-rock reaction between subarc mantle and incoming melt isotopically akin to Jijal gabbroic rocks. The lack in the Kohistan arc of cogenetic ultramafic cumulates complementary to the evolved mafic plutonic rocks implies either (1) that a substantial volume of such ultramafic cumulates was delaminated or torn out by subcrustal mantle flow from the base of the arc crust in extraordinarily short time scales (0.10–0.35 cm/yr), or (2) that the net flux to the Kohistan arc crust was more evolved than primitive arc basalt.

While the global response to HIV and AIDS has realized several successes in achieving universal access to prevention, care and treatment to date, challenges persist in ensuring equal access to these services for most at risk populations. The epidemiology of HIV reflects a stark disparity in access to prevention and treatment services for neglected most-at risk populations, such as men who have sex with men (MSM). World-wide, MSM often experience higher rates of HIV relative to the total population. The reasons for this dynamic are multi-faceted and include high risk behaviors, and cultural as well as structural barriers. For MSM in developing countries, for example, basic services for prevention and treatment of HIV infection have yet to reach the large majority of men. Homophobia and discrimination limit access of MSM to prevention services and markedly increase vulnerability, as do criminalization of same-sex behavior. Decriminalization of same-sex behavior is a structural intervention for prevention of HIV infection and has recently been embraced by a nonbinding statement from the United Nations (Beyrer C,Clin Infect Dis. 2010 May 15;50 Suppl 3:S108-13) In the Caribbean, all of the above mentioned barriers exist. In fact, recent evidence demonstrates that there is a correlation between the decriminalization of homosexuality and lower rates of HIV (UNAIDS). This correlation is attributed to improved access to services. Therefore, The United Nations Development Program (UNDP) has recently launched an initiative to address the current situation regarding men who have sex with men in Guyana where the HIV prevalence in this population is 19.4% in contrast to 1.8% in the total population. This rapid assessment has been commissioned to supplement two previous studies that were conducted in Guyana in informing the design of upcoming activities to support local capacity building to enhance access to services and respect for the human rights protections for MSM. Unfortunately, in Guyana, like much of the Caribbean, MSM tend to be a hard to reach population, perhaps due to elevated levels of stigma and discrimination and difficulty in accessing men who might participate in high risk same sex behaviors yet do not self-identify as an MSM. As a result, there is a relative paucity of data concerning the knowledge, attitudes and behaviors of this total population in Guyana. (i.e. those who self –identify and those who do not) The baseline report is organized as follows: the methodology is explained followed by the study limitations, the review (literature and desk). The report then proceeds with describing the reality of work and working with sexual and gender minorities in Guyana, the status quo and entry points. The main findings of the capacity assessment and focus groups are then discussed. Issues relating to the uniformed forces and health services providers are then presented followed by discussions and conclusions.

Résumé : International audience
The Western Cordillera of Ecuador consists of Cretaceous crustal fragments of oceanic plateaux and superimposed insular arcs, which were accreted to the northwestern South American margin during the Late Cretaceous and Paleocene. Slices of high-grade metabasites, ultramafic rocks, gabbros and basalts, unmetamorphosed radiolarian cherts and scarce garnet-bearing metasediments were randomly exhumed along Miocene to Recent transcurrent faults crosscutting the Western Cordillera. The basalts show geochemical characteristics of oceanic plateau basalts (flat REE patterns, La/Nb = 0.85). The gabbros differ from the basalts in having lower REE levels, positive Eu anomalies, and negative Nb and Ta anomalies; they are interpreted as resulting from arc magmatism. The amphibolites and banded amphibolites have major and trace element chemistry similar to that of oceanic plateau basalts (flat REE patterns, La/Nb = 0.86) or to cumulate gabbros. The granulite shares with oceanic plateaus similar trace element chemistry (flat REE patterns, La/Nb < 1) and εNdi values (+7.6). Continent-derived metasediments are depleted in heavy REE (La/Y = 4.8) and have a negative Eu anomaly. Foliated lherzolites, melagabbronorites and pyroxenites consist of serpentinized olivine + cpx + opx ± Ca-plagioclase. Lherzolites, melagabbronorites and pyroxenites are LREE depleted with positive Eu anomalies, while the harzburgite displays a U-shaped REE pattern. The trace element abundances of the ultramafic rocks are very low (0.1 to 1 times the chondritic and primitive mantle values). The ultramafic rocks represent fragments of depleted mantle, deformed cpx-rich cumulate, and continental lithospheric mantle or mantle contaminated by subduction-fluid. Except the scarce quartz-rich metasediments, all these rocks likely represent remnants of accreted oceanic crustal fragments and associated depleted mantle. Since these samples were randomly sampled at depth by the fault, we propose that the Western Cordillera and its crustal root are mainly of oceanic nature.
