Évolution Comparée De La Douleur Et Du Statut De Travail À La Suite D’Un Programme De Réadaptation Pour Des Travailleurs Ayant Des Troubles Musculo-Squelettiques, Patrick Loisel, Marc Corbière, Marie-José Durand, Marie-France Coutu, Bruno Désorcy, Quan Nha Hong, Karine Genest

Rapports de recherche scientifique

Les troubles musculo-squelettiques (TMS) touchent chaque année plus de 45 000 travailleurs québécois dans tous les secteurs d’activité. Dans un modèle de représentation biopsychosocial des TMS, la question des croyances des principaux acteurs sociaux à propos de l’incapacité et la douleur est fondamentale pour le processus de réadaptation. Plusieurs intervenants de la santé, employeur ou assureur, croient que l’employé ne doit pas se présenter au travail avant d’être complètement rétabli de sa blessure. Paradoxalement, d’autres croient qu’il n’existerait qu’un rapport ténu entre l’absence au travail et la douleur. À notre connaissance, encore peu de travaux se sont intéressés à l’association …

Ergonomic Evaluation Of Shoulder Muscle Activation During Light Weight Hand Tool Exertion Task, Gul Ahmed

Theses

A study was conducted to evaluate the effect of shoulder muscle activation during hand exertion tasks using a light weight hand tool by working individuals. Electromyography (EMG) of trapezius, supraspinatus, triceps, and pectoralis major was conducted for 45°, 0° and -45° arm angles, for three different reaches i.e. normal, maximum and extreme and three different push forces low, medium and high. Ten volunteers participated in the experimental study. The effects of push force and reach distance were found to be statistically significant for all four muscles. However the effect of change of angle was not found to be statistically significant, …

"Sewing A Safety Net: Scarborough's Maritime Community, 1747-1765", Charles Foy

Faculty Research & Creative Activity

From 1747 to 1765 Scarborough created a safety net to keep its maritime dependents from becoming impoverished. A web of kinship connections that permitted sailors to move between land and sea as well as between maritime roles as they aged; the employment of maritime servants; the extensive hiring of elderly seamen; the use of the Seamen’s Sixpence after legislative reform in 1747 to develop locally operated seamen’s hospitals for the benefit of sailors and their families; and strong community support of the hospitals worked together to provide a social safety net that was, by eighteenth century standards, robust and effective.

Using Physiologically-Based Pharmacokinetic Models To Incorporate Chemical And Non-Chemical Stressors Into Cumulative Risk Assessment: A Case Study Of Pesticide Exposures, Susan C. Wason, Thomas J. Smith, Melissa J. Perry, Jonathan I. Levy

Environmental and Occupational Health Faculty Publications

Cumulative risk assessment has been proposed as an approach to evaluate the health risks associated with simultaneous exposure to multiple chemical and non-chemical stressors. Physiologically based pharmacokinetic/pharmacodynamic (PBPK/PD) models can allow for the inclusion and evaluation of multiple stressors, including non-chemical stressors, but studies have not leveraged PBPK/PD models to jointly consider these disparate exposures in a cumulative risk context. In this study, we focused on exposures to organophosphate (OP) pesticides for children in urban low-income environments, where these children would be simultaneously exposed to other pesticides (including pyrethroids) and non-chemical stressors that may modify the effects of these exposures …

Effects Of Temperature On Emergence And Seasonality Of West Nile Virus In California, David M. Hartley, Christopher M. Barker, Arnaud Le Menach, Tianchan Niu, Holly Gaff, William K. Reisen

Biological Sciences Faculty Publications

Temperature has played a critical role in the spatiotemporal dynamics of West Nile virus transmission throughout California from its introduction in 2003 through establishment by 2009. We compared two novel mechanistic measures of transmission risk, the temperature-dependent ratio of virus extrinsic incubation period to the mosquito gonotrophic period (BT), and the fundamental reproductive ratio (R₀) based on a mathematical model, to analyze spatiotemporal patterns of receptivity to viral amplification. Maps of BT and R₀ were created at 20-km scale and compared throughout California to seroconversions in sentinel chicken flocks at half-month intervals. Overall, estimates of BT and …

Linking Authentic Leadership To Positive Employee Health, Behavioral Engagement, And Job Performance, Yan Liu

Doctoral Dissertations

In recent years, there has been increasing interest in the emerging field of positive organizational behavior. The field of Positive Organizational Behavior (POB) has its roots in the concept of "positive psychology" (Bakker & Schaufeli, 2008) but is more narrowly defined as "the study and application of positively oriented human resources strengths and psychological capacities that can be measured, developed, and effectively managed for performance improvement in today's workplace" (Luthans, 2002, p.698). More and more researchers have begun to emphasize what is right with people rather than focusing on what is wrong with people.

Given this opportunity, this dissertation explicitly …
