Central Auditory Gain Modulation In The Rehabilitation Of Workers With Tinnitus, Sylvie Hébert, Philippe Fournier, Marc Schönwiesner

Rapports de recherche scientifique

L’acouphène est un son perçu sans qu’il soit provoqué par une source sonore externe. Cette sensation auditive anormale, par exemple des bourdonnements, des tintements ou des sifflements, affecte une seule ou les deux oreilles. Elle peut grandement détériorer la qualité de vie et l’aptitude au travail d’une partie importante des personnes ayant une perte auditive. Dans les deux études décrites dans ce rapport, le modèle récent appelé gain auditif central a été utilisé pour intégrer les données normales et pathologiques dans un même cadre conceptuel. En bref, le « gain auditif central » est un mécanisme normal postulé pour expliquer …

Design And Manufacture Of An Inertial Cascade Impactor For Industrial Hygiene Purposes, Hector Joel Gortaire

Mechanical & Aerospace Engineering Theses & Dissertations

Inertial cascade impactors are devices commonly used for industrial hygiene and pharmaceutical studies. Their main purpose is to separate particulate matter suspended in aerosols according to their sizes, which can vary from over 10 µm to 0.5 µm. Their versatility and ease of operation make them suitable for on-site sampling; however, designing them requires a careful consideration of the different geometric parameters that characterize them.

In this thesis, a 5-stage inertial cascade impactor was designed, modelled, constructed, and tested. The main design parameter was the volumetric flow rate, 40 l/min, which was provided by a vacuum pump. By continuous iterations, …

Redefining Burnout: Exploring Common Conceptualizations And The Neurophysiology Of Chronic Stress To Establish An Integrated Allostatic Model, Danny A. Guzzi

Dissertations

Burnout is a widely researched stress-related phenomenon associated with numerous adverse outcomes for employees and organizations. Unfortunately, burnout is not well understood and research to this point has been flawed due to a lack of consensus on the definition, dimensionality, and context of the construct. Prevalent conceptualizations of burnout have been criticized for being arbitrarily developed without solid theoretical foundation and for failing to clearly distinguish burnout from depression or other work-related conditions such as compassion fatigue, secondary traumatization, and vicarious traumatization. The current project first examines relevant literature to identify commonalities among prevalent burnout conceptualizations. Then relevant stress research …

Rapports de recherche scientifique

Certains secteurs d’activité sont particulièrement touchés par des problèmes qui affectent la santé et la sécurité des travailleurs. C’est le cas, entre autres, des centres jeunesse où le travail est généralement caractérisé par une demande émotionnelle élevée, attribuable aux contacts fréquents avec des enfants et des familles en crise, et par le manque de ressources nécessaires pour gérer cette demande émotionnelle. On reconnaît d’ailleurs de plus en plus les effets attribuables au « travail émotionnellement exigeant » (TÉE), que ce soit sur le plan de la santé physique ou psychologique (stress post-traumatique, troubles musculosquelettiques, détresse psychologique, absentéisme, roulement de personnel, …
