Dans les romans et nouvelles d’Earl Lovelace, l'île de Trinidad se trouve aux confluents de systèmes antagonistes, branlés par la récente décolonisation. Les forces civiles et religieuses, piliers de l’organisation sociétale, ne peuvent échapper aux dynamiques de transmutation et d’adaptation. Ainsi, dans un contexte de sécularisation et de politisation croissante, le religieux se voit obligé d’écarter toute tendance autarcique, s’il veut triompher de la tentative d’annexion par le politique. Un conflit, dont l’enjeu n’est autre que la survie de l’individu, est dès lors engagé. Cette thèse se propose d’explorer les relations de rivalité et d’usurpation entre pouvoirs civils et religieux de même que l’issue du dépassement de cette dichotomie au sein de la Caraïbe lovelacienne. En d’autres termes, le politique dans la fiction de Lovelace détruit-il le religieux ou fait-il corps avec lui afin que s’opère le passage d’une politique condamnable à une foi praxis de libération ? / In his novels and short stories, Earl Lovelace describes the island of Trinidad as caught in the ebb and flow of two antagonistic systems of thought, both shattered in the event of a sudden decolonisation. Religion and politics, the corner stones of social architecture, have no choice but to undergo changes in view of adaptation. Facing a background of secularisation and growing political consciousness, religion is compelled to lay aside its selfsufficiency to avoid being overthrown by the body politics. As a consequence, a struggle, in which the survival of individuals is at stake, ensues. This thesis offers to explore the rivalries between the religious and political bodies as well as the ability of Lovelace’s fictional Caribbean to overcome this dichotomy. In other words, in Lovelace’s work does polity annihilate religion or act in accordance with it to achieve a move from unworthy politics to a faith aiming at liberation?

Sampling of airborne dust in industry is influenced by the potential health effects associated with human exposure. Health effects depend on mass concentration and particle size which influences the site of pulmonary deposition. Occupational diseases tend to be associated with dust deposition in specific regions of the respiratory tract. The ACGIH size selective TLVs are expressed in three forms: Inhalable Particulate Matter, Thoracic Particulate Matter, and Respirable Particulate Matter. In pneuomoconioses, the amount of dust deposited in the lungs can be estimated by sampling the respirable fraction. Dose-response relationships are derived by relating the health experience of workers to the extent of their exposure to respirable dust. It can be readily seen that validity of these relationships depends primarily on the accuracy of estimation of the exposure dose. Different sampling techniques, such as impactors, horizontal elutriators and cyclones were used for decades to estimate the exposure to respirable dusts. Cyclones have been the most widely utilized. However, the performance curve of the cyclone is considerably different from observed dust deposition data in the human alveolar compartment. Current methods of measuring respirable dust overestimate that dust fraction, which results in underestimating the agent’s toxicity in dose-response relationships. In this investigation, a new concept for sampling respirable dust was proposed and validated. The goal of this study was to design a combined impactor/cyclone device that provides better estimation of the amount of respirable dust. The objectives of this study were: 1) to calibrate ten single-stage impactors previously deigned and machined by Dr. Hammad, 2) to obtain the collection efficiency curves of ten impactor-cyclone combinations by superimposing the collection efficiency curves of impactors on the well-defined cyclone efficiency curve, and 3) to compare the combined efficiency curves to actual human alveolar deposition data, and thus validate this new concept for sampling of respirable dust. The experiment was conducted in a 20’’x20’’x20’’ aerosol testing chamber constructed from aluminum with a glass window. A LoveLace nebulizer with a nominal droplet size of 7 micrometers was used to generate fluorescent monodisperse polystyrene latex aerosols 0.5, 1, 2, and 3 micrometers in diameter. A Vilnius aerosol generator was used to generate fluorescent PSL dry powders 6 micrometers in diameter. The generated aerosols were collected on 37 mm polyvinyl chloride filters positioned after the impactors. Sample fluorescence was determined using a GloMax-Multi Jr fluorometer. Impactor efficiencies at the various sizes were used to construct the collection curves of impactors. Efficiency curves were subsequently superimposed on the cyclone efficiency curve to obtain the final efficiencies of the sampling devices. The results indicated that the cut-off diameters increased with impactor jet size. The new efficiency curves of the sampling devices had similar shapes to actual alveolar deposition as determined experimentally in human subjects. Actually they fell between actual alveolar deposition curves 2 and 4 seconds for mean residence times. The findings from this work can be applied to design a novel respirable dust sampler that provides a realistic estimate of pulmonary deposition to be used in dose- response relationships for the various mineral dusts encountered in general and mining industries. The under estimation of the dust toxicity associated with the current sampling methodology may be one of the reasons for continuous lowering of the TLV and PEL for silica.

As a choreographer working with new media technologies, I recognised a need to develop choreography informed by the digital age. This study was framed by the development of the dance project Ada, over three stages through a qualitative, interdisciplinary process. Artistic practice as research grounded in task based choreographic processes led to the following areas of significance in the study, those being; enacting a narrative, physicalising interactivity, performing virtual dance, and choreographing through a digital perspective. Findings that enunciated the evolution of newmedia choreographic forms and structures arose from reflective practice, dialogue with participants and feedback from a live audience.

Indiana University-Purdue University Indianapolis (IUPUI) / Dance appears often in Anglophone Caribbean literature, usually when a character chooses to celebrate and emphasize her/his freedom from the physical, emotional, and societal constraints that normally keep the body in check. This study examines how a character's political consciousness often emerges in chorus with aesthetic bodily movement and analyzes the symbolic force and political significance of Caribbean dance--both celebratory (as in Carnival) and defensive (as in warrior dances). Furthermore, this study observes how the weight of Western views on dance influences Caribbean transmutations and translations of cultural behavior, ritual acts, and spontaneous movement. The novels studied include Samuel Selvon's "The Lonely Londoners" (1956), Earl Lovelace's "The Dragon Can't Dance" (1979), Paule Marshall's "Praisesong for the Widow" (1983), and Marie-Elena John's "Unburnable" (2006).
