Knowledge is the Key - Internet access, utilization and opinions in Grenada, West Indies Information and knowledge contributes to growth and development through empowering individuals and communities, creating opportunities to improve their living conditions. Technology is advancing rapidly and the Information and Communication Technology, ICT, provides new ways to attain information.

Cycle géodynamique du soufre : le rôle des sédiments subduits / Geodynamic cycling of sulphur : the role of subducted sediments

Pelleter, Anne-Aziliz 27 June 2017 (has links)
Dans l’objectif d’évaluer le devenir de sédiments subduits variablement enrichis en soufre dans des conditions P-T (pression – température) correspondant au toit de la plaque sous un arc volcanique, des expériences de fusion et de cristallisation ont été réalisées en conditions hydratées en presse piston-cylindre(3 GPa ; 650 – 1000°C ; ƒO2 ~ NNO) sur des sédiments naturels (pélite et marne), non dopés en éléments en traces et variablement enrichis en soufre (0, 1 et 2 wt% Sin). Lors de la fusion du sédiment pélitique, des liquides trondhjémitiques à granitiques sont produits en équilibre avec un résidu composé de grenat +disthène ± phengite ± quartz + rutile. Lors de la fusion du sédiment marneux, des liquides granodioritiques sont produits en équilibre avec un résidu constitué de grenat ± épidote ± clinopyroxène ± disthène ± quartz +rutile. L’ajout de soufre dans le système pour une ƒO2 ~ NNO conduit à une précipitation de sulfures. La quantité de fer (Fe2+) disponible dans le système diminue fortement (augmentation du Mg#) et impactegrandement les relations de phases : le grenat, l’épidote et la phengite sont déstabilisées au profit des pyroxènes, de la biotite ou encore de l’amphibole. La distribution des éléments en traces dans le liquide silicaté par rapport au sédiment de départ est également très affectée pour les systèmes dopés en soufre(ex : fractionnement des terres rares). Nous proposons, à partir des données obtenues dans des xénolites mantelliques (Grenade, Petites Antilles) et lors de modélisations géochimiques, que la contribution dans lecoin mantellique de 1 à 3 % de liquides trondhjémitiques/granitiques issus de la fusion de sédiments pélitiques modérément enrichis en soufre (≤ 1 wt% Sin) peut expliquer la variabilité de composition des basaltes du sud de l’arc des Petites Antilles (Grenade et Grenadines). / The main issue of this study is to constrain the fate of subducted sediments variably enriched in sulphur for P-T (pressure – temperature) relevant for the slab at sub-arc depth. Using piston-cylinder apparatus, we performed melting and crystallisation experiments (3 GPa; 650 – 1000°C; ƒO2 ~ NNO) on natural, trace elementundoped and volatile-rich sediments (pelite and marlstone). Experiments were conducted with variable water (5 to 10 wt% H2Oin) and sulphur (0, 1 and 2 wt% Sin) contents. Silicate melts produced by the fluid-present melting of pelite range from trondhjemitic to granitic compositions, are broadly peraluminous and coexist with garnet + kyanite ± phengite ± quartz + rutile. Those produced by the fluid-present melting of marlstone are sodic (granodioritic composition), metaluminous to slightly peraluminous and coexist with garnet ± epidote ± clinopyroxene ± kyanite ± quartz + rutile. Sulphur addition at ƒO2 ~ NNO leads to sulphide precipitation. Thus, iron (Fe2+) contents decrease (Mg# increase) in the system and this strongly impacts phase relationships: garnet, epidote and phengite are consumed in favour of pyroxens, biotite and amphibole. Trace-element distribution between silicate melt and starting bulk for S-doped systems is largely impacted (e.g. rare earth elements fractionation). On the basis of data obtained in mantle xenoliths(Grenada, Lesser Antilles) and from geochemical modelisations, we are suggesting that a contribution in the mantle wedge of 1 to 3 % of trondhjemitic/granitic melts derived from pelitic sediments (≤ 1 wt% Sin) mayaccount for the composition of basalts in the southern part of Lesser Antilles (Grenada and Grenadines).

Key Performance Indicators' Effects on Public Sector Infrastructure Project Efficiency in Grenada

George, Kelvin Michael 01 January 2019 (has links)
Grenada is 1 of 15 developing countries in Caribbean Community known as CARICOM. The infrastructure capital projects in these developing countries are plagued with an array of issues: unethical practices, inadequate supervision, lack of transparency and accountability, inadequate monitoring and evaluation, cost overruns, and inefficiencies. In the 1980s and 1990s, the International Monitory Fund and World Bank introduced a balanced scorecard engineered under the structural adjustment program, but it was unable to improve infrastructure project efficiencies. This qualitative case study sought to understand the role of management key performance indicators (KPIs) on public sector infrastructure capital project efficiency on the island of Grenada. An institutional assessment and development framework and a classical management theoretical framework methodology were used to explore the effects of management KPIs on public sector infrastructure capital projects efficiencies in developing countries. The research incorporated a constructivist philosophy that underpins the evaluation and perception of the government, the National Water and Sewerage Authority (NAWASA), project teams, systems, and stakeholders. A purposive sampling strategy with elements of snowballing was used to obtain 12 representative participants for interviews, and a systematic approach of transcribing, coding, and thematic analysis was done. Findings indicate inadequacies in the BSC performance measure system on infrastructure projects, which justifies the use of comprehensive management KPIs. Positive social change implications of this study include recommendations for comprehensive management KPIs and policies to improve public sector infrastructure project efficiency in Grenada.
