Reconnaissance survey of Galveston Bay sediments for selective nonresidual trace metals

The nonresidual concentrations of five trace metals were determined for 322 sediments that were the product of a systematic sampling program of the entire Galveston Bay system. The nonresidual component of the trace metal concentration (e.g. that fraction of the metals that can be relatively easily removed from the sediments without complete destruction of the sediment particle) was considered to be more indicative of the anthropogenic metal pollution that has impacted the Galveston Bay ecosystem.^ For spatial analysis of the metal concentrations, the Galveston Bay system was divided into nine bay-areas, based on easily definable geological and geographical characteristics. Isopleth mapping analyses of these metal concentrations indicated a direct relationship with the $<$63$\mu$m fraction of the sediment (%FINE) in all of the bay areas. Covariate regression analyses indicated that position of the sediment within the Galveston Bay system (e.g. bay-area) was a better predictor of metal concentration than %FINE. Analysis of variance of the metals versus the bay-areas indicated that the five metals maintained a relatively constant order and magnitude of concentration for all the bay-areas.^ The major shipping channels of the Galveston Bay system, with their associated vessels and transported materials, are a likely source of metal pollution. However, these channels were not depositional corridors of high metal concentration. All metal concentration highs were found to be located away from the channels and associated with %FINE highs in the deeper portions of the bay-areas.^ Disturbance of the sediments, by the proposed widening and deepening of these channels, is not predicted to remobilize the trace metals. A more likely adverse effect on the health of the Galveston Bay ecosystem would come from the increase in turbidity of the water due to the dredging and in an extension of the salt water wedge farther north into the bay system. ^

Musiciens migrants d'origine arabe dans le contexte montréalais : le parcours de la reconnaissance

Ce mémoire traite des parcours de musiciens migrants d’origine arabe à Montréal. Il s’intéresse à la manière dont ces derniers construisent leurs carrières musicales dans ce contexte et acquièrent la reconnaissance des différents acteurs qu’ils côtoient – pairs, intervenants culturels, public. La méthodologie adoptée est de nature qualitative et correspond à une perspective ethnosociologique, le contexte musical de l’étude inscrivant la démarche dans le domaine de la sociomusicologie. Cinq musiciens ayant migré d’un pays arabe avec une pratique musicale préalable ont été rencontrés, ainsi que cinq acteurs du milieu musical qui interagissent avec eux. Ce corpus d’entretiens a été complété par de l’observation et l’étude de traces (ex. : disques, cv). La démarche d’enquête a permis d’élaborer un ensemble de propositions visant à comprendre les phénomènes sociaux observés. Il apparaît que ces musiciens construisent leurs carrières montréalaises grâce à une actualisation et réappropriation originale des sources et influences musicales accumulées au fil de leur vie, processus néanmoins tributaire des rouages du milieu musical. Celui-ci est constitué de multiples acteurs ayant chacun leurs objectifs, intérêts, contraintes vis-à-vis desquels les musiciens doivent s’ajuster, négocier, faire des compromis. Puis, l’ethnicité arabe qui est construite et mise en scène par les performances musicales peut vraisemblablement agir comme outil pour se démarquer dans le contexte montréalais. Cependant, les dynamiques qui sous-tendent les rapports sociaux que ces artistes entretiennent dans la métropole font en sorte qu’ils ont ultimement peu d’emprise sur la manière dont se manifeste la reconnaissance à leur égard et vis-à-vis de leurs pratiques musicales.

Report of geological reconnaissance in south-central Montana and northwestern Wyoming /

In the spring of 1953 a program of field reconnaissance for radioactivity in south-central Montana and northwestern Wyoming was authorized by the U.S. Atomic Energy Commission. Field procedures consisted of testing outcrops along roads, in cliffs, and around rim rocks, and testing mines, prospects and the dumps thereof with the appropriate instruments in an attempt to locate exposures of areas showing anomalous radioactivity and to ascertain the geological conditions under which such radioactivity occurred.
