Informations de base sur la République du Cap Vert L'archipel du Cap Vert est constitué par dix îles et huit îlots situés à environ 500 km de la côte occidentale africaine. Sa superficie est de 4033 km2. Les îles sont d'origine volcanique et sont implantées sur la zone sud-ouest de la plate-forme sénégalaise sur la croûte océanique d'âge comprise entre 140 et 120 millions d'années. Le relief est très accidenté dans les îles les plus jeunes (Fogo, Santiago, Santo Antão et S. Nicolau), mais relativement plat dans les îles plus anciennes (Maio, Boavista e Sal). Les sols sont peu évolués, avec des horizons pédologiques peu différenciés. Par sa situation géographique, dans une zone d'aridité météorologique, le climat du Cap Vert est sahélien du type tropical sec, soumis aux vents alizés du nordest, avec des températures modérées (environ 24ºC) et une faible amplitude thermique dû à l'environnement atlantique. Les précipitations sont généralement faibles sur l'ensemble du pays, ne dépassant pas les 300 mm de moyenne annuelle pour les 65% du territoire situé à moins de 400 m d'altitude. Les zones sous l'influence des alizés étant encore plus sèches (150 mm de moyenne annuelle). Sur les versants situés à plus de 500 m d'altitude faisant face aux alizés, on peut atteindre ou dépasser les 700 mm. Les pluies sont irrégulières et généralement mal distribuées dans le temps et dans l'espace. Le peuplement et son influence sur la biodiversité Après leur colonisation par les humains au cours du XVème siècle, les îles du Cap Vert ont été soumises à une forte exploitation des ressources biologiques. Des facteurs anthropiques avec conséquences directe et indirecte sur la végétation, tels que l'agriculture pluviale, dans la plupart des cas pratiquée sur les fortes pentes des versants, l'utilisation du bois de feu, le surpâturage et l'introduction des espèces exotiques ont contribué à la dégradation graduelle de la végétation et des habitats de l'archipel. Le rôle de ces facteurs a été encore accentué par l'action passif des facteurs intrinsèques tels que l'insularité et la fraction importante du territoire occupée par des zones arides et semi-arides. La végétation des zones arides et semi-arides qui occupent, au Cap Vert, plus de 70% du sol arable du territoire, a un faible pouvoir de régénération. Sa flore insulaire est sensible par le fait d'avoir évolué en l'absence de prédateurs et d'être issues de petites populations avec une diversité génétique limitée et par une aire de dissémination très limitée. La diversité des espèces Il existe au Cap Vert, 110 espèces de bryophytes dont 15 sont endémiques. Du total, 36% sont extinctes ou menacées. Parmi les endémiques 40% sont menacées. Les espèces d’angiospermes sont en nombre de 240 dont 45 sont endémiques. A noter que 27% du total sont extinctes ou menacées. Parmi les endémiques, 54% sont en danger de disparition. La biodiversité animale cours des risques majeures de survie. Des 37 espèces de gastéropodes existantes, 15 sont endémiques dont 67% sont menacées. Les arachnides sont au nombre de 111 dont 46 sont endémiques. Parmi les endémiques, 78% sont menacées. Il existe 470 espèces d'insectes (coléoptères) dont 155 sont endémiques. 84% des taxa endémiques sont menacées. On suppose que du total des 470 espèces, 64% sont disparues ou en danger. L'état actuel de la faune et de la flore a été donné par la Première Liste Rouge du Cap Vert, publiée en 1996 et qui indique un certain nombre de statistiques effrayantes : sont menacées plus de 26% des angiospermes, plus de 40% des bryophytes, plus de 65% des ptéridophytes et plus de 29% des lichens ; plus de 47% des oiseaux, 25% des reptiles terrestres, 64% des coléoptères, plus de 57% des arachnides, plus de 59% des mollusques terrestres. L'archipel du Cap Vert est situé dans la zone tropicale où, selon Nunan (1992), si on exclue les espèces migratoires on peu compter environ 273 espèces de poissons, dont 70% sont endémiques. La liste des espèces de poissons des îles du Cap Vert est assez diversifiée et compte environ une centaine d'espèces appartenant à différentes familles. En matière de diversité biologique marine l'exploitation des ressources dans la ZEE (Zone Economique Exclusive) sont encore loin d'atteindre le potentiel estimé. Néanmoins, il existe quelques espèces qui sont en danger, notamment les tortues et les langoustes. Dans les eaux capverdiennes il existe 5 espèces de tortues : Dermocelys coriacea, Chelonia mydas, Eretmochelys imbricata, Caretta caretta et Lepidochelys olivacea. Les tortues sont d'une façon générale soumises à une exploitation irrationnelle depuis des décades. La viande et les oeufs, surtout de la tortue mâle sont très appréciés. La carapace est utilisée dans la bijouterie (boucles, bagues, colliers, etc.). Parmi les quatre familles de langoustes connues, l'archipel du Cap Vert recèle deux : la Palinuridae (langouste rose, verte et marron) et la Scyllaride (langouste de pierre). A signaler également une espèce endémique, le Palinuris charlestoni. Toutes les espèces existantes au Cap Vert sont exploitées, souvent à la limite de la durabilité. La République du Cap Vert et la Convention sur la Biodiversité Le Cap Vert a signé la Convention sur la biodiversité en juin 1992 et l'a ratifié en mars 1995. Pour remplir les obligations découlant de l'adoption de la Convention, le pays a complété sa Stratégie Nationale et Plan d'Action sur la Biodiversité en février 1999. Une institution responsable pour la mise en oeuvre de la politique nationale en matière de l'environnement a été créée, le Secrétariat Exécutif pour l'Environnement (SEPA). Le Plan d'Action National a identifié 21 objectifs divisés en huit groupes thèmatiques et contient des activités jusqu'à l'an 2010. Parallèlement à ces actions, la Loi de Base pour l'Environnement, le Code de l'Environnement, le Code de l'Eau et le Code Forestier ont été adoptés. Ce nouveau Code Forestier a été élaboré afin d'actualiser les normes pour une gestion durable des ressources et le transfert des compétences aux régions et communautés. Au niveau stratégique le Cap Vert a élaboré son Programme d'Action National pour l'Environnement (PANA) et a développé le Programme d'Action National de Lutte Contre la Désertification (PAN-LCD) en utilisant l'approche participative faisant appel à tous les acteurs de la société civile y inclus les associations et ONG. Au niveau international le Cap Vert a adhéré aux conventions telles que la biodiversité, les changements climatiques et le contrôle de la désertification. Le pays a également signé les conventions suivantes : Convention des Nations Unies sur le Droit de la Mer, Convention relative à la Protection du Patrimoine Mondial Culturel et Naturel, Convention de Bâle sur les mouvements trans-frontaliers, Convention internationale pour la Prévention de la pollution par des bateaux, Convention de Vienne sur la protection de la couche de l'ozone, Protocole de Montréal sur les substances qui appauvrissent la couche de l'ozone. La mise en oeuvre de la stratégie nationale sur la Diversité Biologique permettra une meilleure gestion de l'eau, des ressources naturelles et des espaces, l'introduction de nouvelles espèces et de nouvelles technologies alternatives pour l'agriculture et l'élevage ainsi que la création de nouveaux emplois alternatifs, à partir des activités génératrices de revenus, et de diminuer ainsi, la pression sur les ressources naturelles.

La Bible s’ouvre par deux compositions poétiques d’Alcuin qui encadrent l’Épître de saint Jérôme à Paulinus, « Frater Ambrosius... » (ff. 1-2r : Monumenta Germaniae Historica, Poetae latinae, I, 1, p. 287, LXVIII-LXX, v. 1-200 ; ff. 4r-v : Monumenta Germaniae Historica, Poetae latinae, I, 1, p. 283-284, LXV, I-III). La fin manque: la Bible s'interrompt à la fin de l'Epître de saint Paul aux Colossiens.

Background: Interventional catheterization is being increasingly used for relief of residual lesions in congenital heart disease. Exact anatomical imaging is crucial in the planning of an intervention. This can be provided non-invasively and without radiation by contrast-enhanced MR angiography (CEMRA). Aim: To evaluate the accuracy of the measurements of the vessels obtained by CEMRA in comparison to those obtained by conventional X-ray angiography (CXA). Methods: Retrospective blinded measurement of the diameters of aorta and pulmonary arteries on the CEMRA and CXA images, in the same locations. Comparison of the results by Pearson correlation and by calculating the limits of agreement. Results: Twenty-one children with congenital heart disease, mean age 5.6 +- 5.2 years, weight 21.1 +- 18.4 kg, underwent CEMRA and catheterization for assessment or treatment of a residual lesion. The time interval between the CEMRA and the CXA examination was 2.6 +- 2.3 months. A total of 98 measurements, 37 of the aorta and 61 of the pulmonary arteries were performed on the images obtained by each technique. The correlation between CEMRA and CXA measurements was excellent, r = 0.97, p < 0.0001. The mean difference between the two techniques was 0.018 +- 1.1mm; the limits of agreement were -2.14 and +2.18mm. Similar agreement was found for measures of the aorta (r +- 0.97, mean difference 0.20 = 1.08 mm) and of the pulmonary arteries (r +- 0.97, mean difference 0.048 = 0.89 mm). Conclusions: CEMRA provide accurate quantitative anatomical information, which highly agrees with CXA data, and can therefore be used for planning interventional catheterization.

Quality of care is qualified as a main determinant of the demand forvoluntary private health insurance (PHI) in National Health Systems(NHS). This paper provides new evidence on the influence of the qualitygap between public and private health insurance and other demanddeterminants in the demand for PHI in Catalonia. The demand for PHI ismodelled as a demand for health care quality. Unlike previous studies, the database employed allows for the development of a link between thetheoretical and the empirical model dealing with unobserved heterogeneityand endogeneity issues. Results suggest that a rise in PHI qualityenhances an equivalent influence in the demand for PHI as an equalreduction of NHS quality. Income and price elasticity estimates areconsistent with the observed feature that PHI appears to be a luxurygood and individuals tend to be relatively insensible to tax relief'sand monetary co-payments in insurance contracts.

Today’s ride departs Ames and heads towards Nevada. The Ames area is one of the classic areas to view elongated hummocks. These landforms are discontinous, lower relief curvilinear ridges which are east-west trending features. At one time geologists thought these hummocks formed at the base of the glacier due to glacial movement. It is now understood that these features may have developed within the glacier, in a large crevasse field that formed behind the ice (Bemis Moraine) margin as the ice stagnated and melted.

The archipelago of Cape Verde is made up of ten islands and nine islets and is located between latitudes 14º 28' N and 17º 12' N and longitudes 22º 40' W and 25º 22' W. It is located approximately 500 km from the Senegal coast in West Africa (Figure 1). The islands are divided into two groups: Windward and Leeward. The Windward group is composed of the islands of Santo Antão, São Vicente, Santa Luzia, São Nicolau, Sal and Boavista; and the Leeward group is composed of the islands Maio, Santiago, Fogo and Brava. The archipelago has a total land surface of 4,033 km2 and an Economic Exclusive Zone (ZEE) that extends for approximately 734,000 km2. In general, the relief is very steep, culminating with high elevations (e.g. 2,829 m on Fogo and 1,979 m on Santo Antão). The surface area, geophysical configuration and geology vary greatly from one island to the next. Cape Verde, due to its geomorphology, has a dense and complex hydrographical network. However, there are no permanent water courses and temporary water courses run only during the rainy season. These temporary water courses drain quickly towards the main watersheds, where, unless captured by artificial means, continue rapidly to lower areas and to the sea. This applies equally to the flatter islands. The largest watershed is Rabil with an area of 199.2 km2. The watershed areas on other islands extend over less than 70 km2. Cape Verde is both a least developed country (LDC) and a small island development state (SIDS). In 2002, the population of Cape Verde was estimated at approximately 451,000, of whom 52% were women and 48% men. The population was growing at an average 2.4% per year, and the urban population was estimated at 53.7 %. Over the past 15 years, the Government has implemented a successful development strategy, leading to a sustained economic growth anchored on development of the private sector and the integration of Cape Verde into the world economy. During this period, the tertiary sector has become increasingly important, with strong growth in the tourism, transport, banking and trade sectors. Overall, the quality of life indicators show substantial improvements in almost all areas: housing conditions, access to drinking water and sanitation, use of modern energy in both lighting and cooking, access to health services and education. Despite these overall socio-economic successes, the primary sector has witnessed limited progress. Weak performance in the primary sector has had a severe negative impact on the incomes and poverty risks faced by rural workers1. Moreover, relative poverty has increased significantly during the past decade. The poverty profile shows that: (i) extreme poverty is mostly found in rural areas, although it has also increased in urban areas; (ii) poverty is more likely to occur when the head of the household is a woman; (iii) poverty increases with family size; (iv) education significantly affects poverty; (v) the predominantly agricultural islands of Santo Antão and Fogo have the highest poverty rates; (vi) unemployment affects the poor more than the nonpoor; (vii) agriculture and fisheries workers are more likely to be poor than those in other sectors. Therefore, the fight against poverty and income inequalities remains one of the greatest challenges for Cape Verde authorities. The various governments of Cape Verde over the last decade have demonstrated a commitment to improving governance, notably by encouraging a democratic culture that guarantees stability and democratic changes without conflicts. This democratic governance offers a space for a wider participation of citizens in public management and consolidates social cohesion. However, there are some remaining challenges related to democratic governance and the gains must be systematically monitored. Finally, it is worth emphasizing that the country’s insularity has stimulated a movement to decentralized governance, although social inequalities and contrasts from one island to the next constitute, at the same time, challenges and opportunities.

We revisit the debt overhang question. We first use non-parametric techniques to isolate a panel of countries on the downward sloping section of a debt Laffer curve. In particular, overhang countries are ones where a threshold level of debt is reached in sample, beyond which (initial) debt ends up lowering (subsequent)growth. On average, significantly negative coefficients appear when debt face value reaches 60 percent of GDP or 200 percent of exports, and when its present value reaches 40 percent of GDP or 140 percent of exports. Second, we depart from reduced form growth regressions and perform direct tests of the theory on the thus selected sample of overhang countries. In the spirit of event studies, we ask whether, as overhang level of debt is reached: (i)investment falls precipitously as it should when it becomes optimal to default, (ii) economic policy deteriorates observably, as it should when debt contracts become unable to elicit effort on the part of the debtor, and (iii) the terms of borrowing worsen noticeably, as they should when it becomes optimal for creditors to pre-empt default and exact punitive interest rates. We find a systematic response of investment, particularly when property rights are weakly enforced, some worsening of the policy environment, and a fall in interest rates. This easing of borrowing conditions happens because lending by the private sector virtually disappears in overhang situations, and multilateral agencies step in with concessional rates. Thus, while debt relief is likely to improve economic policy (and especially investment) in overhang countries, it is doubtful that it would ease their terms of borrowing, or the burden of debt.

O presente trabalho analisa a relação entre a mulher e a problemática da pobreza e da insegurança alimentar no concelho de Santa Cruz em Cabo-Verde. Organizações internacionais como a Organização das Nações Unidas dizem que a pobreza tem o rosto da mulher, pois a maioria dos 1,2 bilhões de pobres são mulheres; as mulheres trabalham mais do que 50% de todas as horas trabalhadas no mundo, porém só 30% do trabalho feminino aufere remuneração, enquanto esta percentagem para o trabalho masculino ronda os 75%; as mulheres ganham acentuadamente menos do que os homens e ascendem raramente a cargos de relevo; a maioria dos analfabetos são mulheres; uma em cada três mulheres é chefe de família, tendo que assumir sozinha o sustento e a educação dos filhos. Por outro lado, dados da FAO indicam que a mulher desempenha um papel fundamental na alimentação da família, produzindo mais de metade de todos os alimentos cultivados. No entanto, o seu papel fundamental como produtoras e fornecedoras de alimento e a sua crucial contribuição para a segurança alimentar familiar, nem sempre foi tido em devida conta. Partindo desta realidade global, o trabalho centra a sua atenção nas mulheres na Bacia Hidrográfica dos Picos no concelho de Santa Cruz em Cabo Verde, procurando pôr em relevo o seu papel como produtora e como gestora de alimentos e as estratégias que ela utiliza para minimizar situações de pobreza.

Object: The authors sought to establish whether the safety-efficacy of Gamma Knife radiosurgery (GKRS) as a second treatment for intractable trigeminal neuralgia (ITN) are influenced by prior microvascular decompression (MVD) which remains, for some of the authors, the reference technique. Methods: Between July 1992 and November 2010, 737 patients have been operated with GKRS for ITN and prospectively evaluated in Timone University Hospital in Marseille, France. Among these, 54 patients had a previous MVD history. Radiosurgery using a Gamma Knife (model B or C or Perfexion) was performed relying on both MR and CT targeting. A single 4 mm isocenter was positioned in the cisternal portion of the trigeminal nerve at a median distance of 7.6 mm (range 3.9- 11.9) anteriorly to the emergence of the nerve (retrogasserian target). A median maximum dose of 85 Gy (range 70-90) was delivered. Are further analyzed only 45 patients with previous MVD and a follow-up longer than one year (the patients with megadolichobasilar artery compression and multiple sclerosis were excluded). Results: The median age in this series was 56.75 years (range 28.09-82.39). The median follow-up period was 39.48 months (range 14.10-144.65). All the patients had a past history of surgery, with at least one previous failed MVD, but also a radiofrequency lesion (RFL) in 16 (35.6%) patients, balloon microcompression in 7 (15.6%) patients and glycerol rhizotomy in 1 case (2.2%). Thirty-five patients (77.8%) were initially pain free in a median time of 14 days (range 0, 180). Patients from this group had less probability of being pain free compared to our global population of essential trigeminal neuralgia without previous MVD history (p=0.010, hazard ratio of 0.64). Their probability of remaining pain free at 3, 5, 7 and 10 years was 66.5%, 59.1%, 59.1% and 44.3%, respectively. Twelve patients (34.3%) initially pain free experienced a recurrence with a median delay of 31.21 months (range 3.40-89.93). The hypoesthesia actuarial rate at 1 year was 9.1% and remained stable till 12 years with a median delay of onset of 8 months (range 8-8). Conclusions: Retrogasserian GKRS proofed to be safe and effective on the long-term basis even after failed previous MVD. Even if the initial result of pain free was of only 77.8%, the toxicity was low with only 9.1% hypoesthesia. No patient reported a bothersome hypoesthesia. The probability of maintaining pain relief in long-term was of 44.3% at 10 years.

Between 1986 and 1997, 13 shoulders in adult patients who had severe polyarticular juvenile idiopathic arthritis were treated with primary arthroplasty. Eleven shoulders were evaluated retrospectively by an independent observer with a mean follow-up of 9 years. Patient evaluation included pain Visual Analogue Scale, range of motion, Disabilities of the Arm, Shoulder and Hand score, and Short-Form 36. Patients' pain decreased significantly after surgery (mean 6.7). Forward elevation improved on average by 41.1 degrees and external rotation by 39.1 degrees , without evidence of shoulder instability. Final Short-Form 36 scores and Disabilities of the Arm, Shoulder and Hand results (mean, 44.7) were poor, but all patients rated themselves satisfied with the procedure. Shoulder arthroplasty provided pain relief for end-stage shoulder involvement in adult juvenile idiopathic arthritis. Improvement in external rotation in this severely affected group appears to have a beneficial effect on functional outcome.

Faced with recurrent drought and famine during five centuries of human occupation, the small and densely populated Cape Verde Islands have a history of severe environmental problems. The arid climate and steep, rocky terrain provide scant resources for traditional subsistance farming under the best conditions, and in years of low rainfall the failure of rainfed crops causes massive food shortages. Agricultural use of steep slopes where rainfall is highest has led to soil erosion, as has removal of the island's vegetation for fuel and livestock. Pressure on the vegetation is particularly severe in dry years. International aid can provide relief from famine, and the introduction of modern agricultural and conservation techniques can improve the land and increase yield, but it is unlikely that Cape Verde can ever be entirely self -sufficient in food. Ultimately, the solution of Cape Verde's economic and environmental problems will probably require the development of productive urban jobs so the population can shift away from the intensive and destructive use of land for subsistance farming. In the meantime, the people of Cape Verde can best be served by instituting fundamental measures to conserve and restore the land so that it can be used to its fullest potential. The primary environmental problems in Cape Verde today are: 1. Soil degradation. Encouraged by brief but heavy rains and steep slopes, soil erosion is made worse by lack of vegetation. Soils are also low in organic matter due to the practice of completely removing crop plants and natural vegetation for food, fuel or livestock feed. 2. Water shortage. Brief and erratic rainfall in combination with rapid runoff makes surface water scarce and difficult to use. Groundwater supplies can be better developed but capabilities are poorly known and the complex nature of the geological substrate makes estimation difficult. Water is the critical limiting factor to the agricultural capability of the islands. 3. Fuel shortage. Demand for fuel is intense and has resulted in the virtual elimination of native vegetation. Fuelwood supplies are becoming more and more scarce and costly. Development of managed fuelwood plantations and alternate energy sources is required. 4. Inappropriate land use. Much of the land now used for raising crops or livestock is too steep or too arid for these purposes, causing erosion and destruction of vegetation. Improving yield in more appropriate areas and encouraging less damaging uses of the remaining marginal lands can help to alleviate this problem.
