Description : Rapport à l'Etat et au politique : pratiques locales de la distance et de la proximité. La communication interroge la revendication de la mise en place d'une « préférence locale » (ou « régionale » si l'on préfère la désigner par un euphémisme) dans le recrutement ou la promotion des personnes employées dans un département d'Outre-mer. Elle entend procéder à une clarification du cadrage théorique des investigations sur cet objet, davantage qu'à une présentation de résultats d'enquête. Elle souligne la forte contrariété que soulève cette revendication, au moins en première analyse, entre deux exigences majeures : connaître et reconnaître les « grands principes » auxquels tout corps politique ne saurait déroger sous peine d'exploser

Description : The import data from the Ministry of Trade indicates that Suriname has increased pesticides imports over the last five years. According to research evidence, as much as 80% of potential production in various crops including rice would be lost as a result of agricultural pests without crop protection measures. Even though the benefits of chemical pesticides use are clear, negative health and environmental impacts of their use are also evident. In lieu of this information a study was conducted to determine small rice farmers? perceptions on their knowledge of pesticide use, and safety of pesticides in rice production For this investigation a questionnaire was adapted from a pesticide use survey to generate and collect meaningful data on perceptions of small rice farmer?s knowledge and practices related to pesticide use and safety aspects in rice production in Nickerie. The sample population consisted of 200 small rice farmers.?The collected data was analyzed using SPSS and Microsoft Excel. Descriptive statistics and correlation were used to describe the data. Findings reveal that the rice farmers are male, on the average older than 50 years and have more than 15 years of experience with rice production. Results also reveal that farmers perceive the recommended dosage as too little and therefore increase the dosage. They often mix different types of pesticides and do not use all of their protective equipment while spraying. Based on the results it is recommended to develop pesticide policies to stimulate farmers to practice safe pesticide use in Suriname. Les données d'importation du ministère du commerce indiquent que le Surinam a augmenté des importations de pesticides au cours des cinq dernières années. Selon des preuves de recherches, pas moins de 80% de production potentielle dans diverses cultures comprenant le riz serait perdu en raison des parasites agricoles sans mesures de protection des cultures. Quoique les avantages d'une utilité chimique de pesticides soient clairs, la santé et les impacts sur l'environnement négatifs de leur utilisation est également évident. Au lieu de cette information une étude a été entreprise pour déterminer les perceptions des petits agriculteurs de riz sur leur connaissance d'utilisation de pesticide, et la sécurité des pesticides dans la production de riz. Pour cette enquête un questionnaire a été adapté d'une enquête d'utilisation de pesticide pour se produire et rassembler des données significatives sur des perceptions de la connaissance du petit agriculteur de riz et des pratiques s'est rapporté aux conditions de sécurité d'utiliser-et de pesticide dans la production de riz dans Nickerie. La population témoin s'est composée de 200 petits agriculteurs de riz. Les données rassemblées ont été analysées utilisant SPSS et Microsoft Excel. Des statistiques descriptives et la corrélation ont été employées pour décrire les données. Les résultats indiquent que les agriculteurs de riz sont masculins, les plus vieux que 50 années moyennes et ont plus de 15 ans d'expérience avec la production de riz. Les résultats indiquent également que les agriculteurs perçoivent le dosage recommandé en tant que trop peu et augmentent donc le dosage. Ils souvent mélangent différents types de pesticides et n'utilisent pas tout leur équipement de protection tout en pulvérisant. Basé sur les résultats on lui recommande de développer des politiques de pesticide pour stimuler des agriculteurs pratiquer l'utilisation sûre de pesticide au Surinam.

Résumé : From Wikipedia (March 23, 2013) http://en.wikipedia.org/wiki/Richard_Robert_Madden : Richard Robert Madden (born Dublin, Ireland 22 August 1798, died Dublin, 5 February 1886) was an Irish doctor, writer, abolitionist and historian of the United Irishmen. He was born at Wormwood Gate, Dublin to Edward Madden, a silk manufacturer. He was educated at private schools. He studied medicine in Paris, Italy, and St George's Hospital, London. While in Naples he became acquainted with Lady Blessington and her circle.[1] Madden was employed in the British civil service from 1833, first as a justice of the peace in Jamaica, where he was one of six Special Magistrates sent to oversee the eventual liberation of Jamaica's slave population, according to the terms of the Slavery Abolition Act 1833. From 1835 he was Superintendent of the freed Africans in Havana. His son, Thomas More Madden, who later became a surgeon and writer, was born there. In 1839 he became the investigating officer into the slave trade on the west coast of Africa, in 1847 the secretary for the West Australian colonies. He returned to Dublin and in 1850 he was named secretary of the Office for Loan Funds in Dublin.[2] He died at his home in Booterstown, just south of Dublin city, in 1886 and is interred in Donnybrook Cemetery.

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 : The subcellular fractionation of the digestive gland cells of the common cuttlefish Sepia officinalis was performed to investigate the distribution of metals between organelles and cytosol and the different cytosolic fractions separated by gel-filtration chromatography. Total metal concentrations vary over 3 orders of magnitude, ranging from dwt for Pb to dwt for Zn. With the exception of Cd, Co, and Cu, metals were mostly bound to the organelles. Whereas no specific organelle compartment was found for Mn, Ph, and Zn, Fe was mainly associated with nucleus, brown body, and "boule" fraction (i.e., 52%) and 44% of the total Ag was contained in the lysosomal and mitochondria enriched fraction. The link of metals with hydrosoluble proteins in the cytosolic fraction was investigated at 254 and 280 not. Direct relationship between cytosolic metal and metallothioneins could only be established for Ag and Cu, whereas Cd and Zn seem to mainly bind high (> 70 kDa) and low (< 4 kDa) molecular weight proteins.

Résumé : Sea-surface temperature images of the coastal upwelling regions off Northwest Africa show that the core of upwelling is sometimes located far from the coast. This has been documented in three regions that share a common feature, namely a wide and shallow continental shelf. This upwelling feature plays a key role in the ecology of the Canary Current System. It creates an innerfront which provides retention for biological material, e.g. fish eggs and larvae, in the highly productive nearshore environment. An analytical model has been developed based on a two dimensional extension of Ekman's solution. The linear and steady response of a homogeneous ocean forced by an upwelling-favorable wind provides a mechanism for the upwelling separation from the coast. The merging of the surface and bottom Ekman layers induces a very weak cross-shore circulation and a "kinematic barrier" for the Ekman transport divergence. In the case of an alongshore wind, the barrier is located near the isobath h ≈ 0.4D, where D is the thickness of Ekman layers. This yields an upwelling cell which is essentially concentrated in the region 0.5D < h < 1.25D, with upwelling occurring preferentially near the isobath h ≈ 0.6D. It turns out that the cross-shore width of upwelling scales with D/S, the ratio of Ekman depth to bottom topographic slope. The application of this solution to real bathymetric profiles rationalizes, not only the offshore upwelling observations in Northwest Africa, but also the influence of topography on the cross-shelf structure of a wind-driven coastal upwelling. The model also quantifies the effect of the cross-shore wind component showing how it drives the nearshore pressure gradient adjustment and how it affects the upwelling. A linear numerical experiment reproduces the theoretical steady solution, thereby allowing investigation of the transient regime. Relaxation of the hypothesis in the numerical model validates the linear assumption of the theory and then allows investigation of the sensitivity to friction parameterizations and the influence of stratification. The latter leads to an "oscillation" of the upwelling cell with seaward migration driven by outcropping and homogeneization of the water column, and, coastal incursion driven by a "boundary layers splitting" process caused by shoreward advection of the isopycnal dome and stratification of the inner shelf.

Description : Mulch application of Sargassum seaweed (Sargassum spp.) to soil can help to reduce beach contamination in the Caribbean Region while providing beneficial horticultural effects. This study investigated the effects of fresh Sargassum mulch on soil properties and plant growth in a test crop of tomato (Solanum lycopersicum L. â? ? HA 3019â? TM). Fresh Sargassum material (washed and unwashed) was applied as mulches (0, 5 and 8cm thick) to small field plots one week after transplanting of 3-week-old seedlings. The mulch material was raked away from the plots after three weeks exposure. Observations on soil moisture, electrical conductivity, pH and biological activity, and plant growth were made at 1 to 2-week intervals over a 6-week period with additional soil measurements after 10 weeks. Soil biological activity (respiration) was increased by the Sargassum mulch with values being similar for the 5cm and 8cm mulch layers. Soil moisture content, pH and electrical conductivity (EC) were increased as the mulch layer increased and EC values were only marginally reduced by Sargassum washing. An increase in plant growth compared to the control treatment was noted only in the washed Sargassum treatments. Potential benefits of Sargassum seaweed mulches on soil properties and plant growth can be nullified due to soil salinization effects.

Extrait de : "Edouard Glissant, l'éclat et l'obscur" : colloque international, du 19 au 23 mars 2018. Université des Antilles
Description : Selon le Professseur Frédéric Lefrançois, les multiples facettes de l'univers conceptuel échafaudé à travers la poétique d'Edouard Glissant confèrent à sa pensée la profondeur et la richesse d'un opus magnum habité par l'incessante question de la Relation. En son principe, cette idée maîtresse agit à l'image d'un architecte investi d'une mission singulière : celle de faire advenir de l'informe et du multiforme, un plan, une carte, pour assister dans ses avancées l'avenir des cultures en contact. Ainsi, en substance, cette relation est à la fois organique - en ce qu'elle a trait à l'agrégation du divers et du composite - et synthétique, parce qu'elle génère une poétique du divers dans laquelle le tout et la partie entrent en résonance... Ordo ab chao. En ces trois mots tiennent donc l'essence et la finalité d'un propos tour à tour translucide ou opaque, selon le dessein visé, et qu'il nous appartient aujourd'hui de saisir. En pareille matière, l'élan des métaphores, puisé d'un substrat psychosociologique d'une rare densité, s'avère un puissant allié. S'y adjoint la quête de vérité expérientielle, qui n'épargne en rien les aspects problématiques de l'antillanité. Selon quelles modalités passe-t-on des ténèbres à la lumière ? Sur quelle trame conceptuelle et poétique l'écheveau de la mémoire est-il tissé ? Faut-il y voir la tracée d'une destinée manifeste ou l'ambition scripturaire d'un démiurge ? Le Professeur envisage de contribuer à cette investigation en mettant au jour le dénominateur commun entre les fractions d'identité où le génie créateur glissantien se dévoile pour se mettre au service d'une langue poétique nouvelle.

Description : Practical uses for Sargassum are sought regionally as our coastlines continue to be flooded by sargassum blooms floating ashore. This study investigated the potential benefits of Sargassum (Sargassum spp.) mulch in sweet potato production at Golden Ridge, St. George, Barbados, during a drought period (November 2015-March 2016). Treatment consisted of combinations of two cultivars of sweet potato (?E? and ?CBS 32?, main-plots) and washed/unwashed Sargassum mulches (sub-plots) of different ages (approximately 4 weeks old and fresh, sub-sub-plots) with four replications. Sargassum mulch was applied to the furrows of plots (6m2) four weeks after planting at a rate of 10 t ha-1 and yield, growth and soil parameters were monitored at periodic intervals. Yield (t ha-1) was highest for the 4-weeks old Sargassum mulch treatment, and the number of marketable tubers was highest for the unwashed 4-weeks old Sargassum treatment. The number of tubers with Euscepes postfaciatus (Scarabee) pest damage was decreased by the Sargassum mulch treatments especially for the 4-weeks old unwashed Sargassum. Vine growth was taller for cultivar ?E? and for the washed Sargassum treatments. Chlorophyll indices were higher in ?CBS 32? than in cultivar ?E? and were lower in Sargassum treated plots. Moisture content in the top 10cm of soil was consistently low and greater in plots of cultivar ?E? than in those of ?CBS 32?. There appears to be some potential for the use of aged Sargassum mulches for improving growth, pest management and yields of sweet potato and further investigations are needed.

Résumé : Mud volcanism is an important natural source of the greenhouse gas methane to the hydrosphere and atmosphere(1,2). Recent investigations show that the number of active submarine mud volcanoes might be much higher than anticipated ( for example, see refs 3 - 5), and that gas emitted from deep-sea seeps might reach the upper mixed ocean(6-8). Unfortunately, global methane emission from active submarine mud volcanoes cannot be quantified because their number and gas release are unknown(9). It is also unclear how efficiently methane-oxidizing microorganisms remove methane. Here we investigate the methane-emitting Haakon Mosby Mud Volcano (HMMV, Barents Sea, 72 degrees N, 14 degrees 44' E; 1,250 m water depth) to provide quantitative estimates of the in situ composition, distribution and activity of methanotrophs in relation to gas emission. The HMMV hosts three key communities: aerobic methanotrophic bacteria (Methylococcales), anaerobic methanotrophic archaea (ANME-2) thriving below siboglinid tubeworms, and a previously undescribed clade of archaea (ANME-3) associated with bacterial mats. We found that the upward flow of sulphate- and oxygen-free mud volcano fluids restricts the availability of these electron acceptors for methane oxidation, and hence the habitat range of methanotrophs. This mechanism limits the capacity of the microbial methane filter at active marine mud volcanoes to <40% of the total flux.

Résumé : This cigar-making industry has contributed materially to the development and growth of Tampa during the last five years, and it promises much greater benefit in the future. It was in October, 1885, that Martinez Ybor & Co., who began manufacturing in Havana in 1854, and afterward put up a large factory in Key West, came to Tampa to investigate the resources and advantages offered for cigar-making. They soon afterward purchased forty acres of land in the Fourth Ward, cleared it of the pines, wild-oats and gophers, and built a factory, a large boarding-house or hotel, and several small cottages for the workmen whom they brought from Key West and Havana. The venture proved a success from the start and improvements were added. The original factory, a wooden structure, is now the opera house, and a large brick factory has succeeded the first one, where the daily output of the 450 cigar makers employed is40,000 to 50,000 cigars. Then came Sanchez & Haya, Emilio Pons, and others, and all declare that they are doing an excellent business.

Résumé : International audience
The hematocrit-to-viscosity ratio (HVR) has been widely used has an estimate of red blood cell (RBC) oxygen transport effectiveness into the microvasculature or as an oxygen delivery index. However, no study investigated the possibility of HVR to truly reflect RBC oxygen transport effectiveness or to be an oxygen delivery index. We measured blood viscosity at high shear rate (225 s-1), hematocrit, HVR, as well as the microvascular oxyhemoglobin saturation (TOI; tissue oxygen index) by spatial resolved near-infrared spectroscopy (NIRS) at cerebral and muscle levels in three population known to have various degrees of hemorheological abnormalities: healthy subjects (AA), patients with sickle cell SC disease (SC) characterized by moderate anemia and patients with sickle cell anemia (SS) marked by severe anemia. At both the cerebral and muscle level, HVR was positively correlated with TOI (r = 0.28; p = 0.03 and r = 0.38; p = 0.003, at the cerebral and muscle level, respectively). These findings suggest that HVR probably play a key role in blood flow and hemodynamic regulation in the microvasculature, hence modulating the amount of oxygen available for tissues. Nevertheless, the strengths of the associations are weak (R2 < 0.50), suggesting that other determinants modulate microvascular blood flow and oxygenation, such as vascular geometry and vasomotor reserve.
