Effet De La Perte Auditive Et Du Port De Protecteurs Auditifs Sur La Perception Et La Localisation Auditive Des Alarmes De Recul, Véronique Vaillancourt, Chantal Laroche, Christian Giguère, Hugues Nélisse

Rapports de recherche scientifique

Chaque année, des travailleurs se font heurter par un véhicule qui manœuvre en marche arrière. Certaines caractéristiques des alarmes de recul conventionnellement utilisées en milieu de travail (alarmes tonales « bip-bip ») compromettent leur performance à avertir adéquatement les travailleurs de l’approche d’un véhicule, du moins comparativement aux plus récentes alarmes à large bande (« pshit-pshit »). On cite trois principaux désavantages de l’alarme tonale, soit une plus grande difficulté à localiser la provenance du signal sonore dans l’espace, un patron de propagation sonore irrégulier derrière le véhicule lourd, ainsi qu’une nuisance sonore (ou pollution sonore) accrue.

Rapports de recherche scientifique

Contexte et objectif de la recherche

Certains travailleurs ayant subi une lésion professionnelle présentent des difficultés à se maintenir au travail à long terme au retour d’une période d’absence, et ce, même après avoir reçu des services de réadaptation. Les professionnels de la réadaptation ont un rôle à jouer pour favoriser ce maintien sain et durable au travail, notamment par le soutien au développement des comportements préventifs chez les travailleurs. En effet, de récentes études ont permis de développer le Modèle des comportements préventifs au travail (MCPT) qui décrit six comportements que les travailleurs peuvent adopter en interaction avec leur …

This study explored contributing factors to STS and burnout and coping efforts among faculty, students, and staff working in a capacity in which they provide non-instructional support to programs or centers focusing on marginalized student populations. Participants (N=56) represented twenty-two U.S. regional universities, and were a subset of respondents to a larger mixed-methods study (n=559). Qualitative responses to three open-ended questions on challenges and coping efforts were analyzed …

Eye Safety In Dentistry, Marie T. Fluent Dds, Cdipc

The Journal of the Michigan Dental Association

In this article, Dr. Fluent underscores the importance of eye safety from vision loss that ended her clinical dental career. The article emphasizes the prevalence of ocular injuries in occupational settings, with about 2,000 U.S. workers suffering job-related eye injuries daily. Dental professionals face multiple eye hazards, including flying debris, chemicals, and infectious materials. Protective eyewear is crucial, with the CDC and OSHA recommending its use.

A significant concern is the "bottom gap" in protective eyewear, which exposes dental personnel to risks. The article introduces a new ANSI standard, ANSI/ISEA Z87.62-2021, to standardize eye and face protection against bloodborne pathogens …

Mise Au Point Et Validation D’Une Approche Terrain De Prédiction Des Chargements Au Dos Basée Sur Des Données De Laboratoire, Alain Delisle, François Thénault, André Plamondon, Hakim Mecheri

Rapports de recherche scientifique

Les troubles musculosquelettiques (TMS) et particulièrement ceux au bas du dos affectent de nombreux travailleuses et travailleurs chaque année au Québec (Vézina et al., 2011). Le chargement mécanique au bas dos est reconnu comme un facteur de risque pouvant mener au développement de maux de dos, et la manutention de charges peut occasionner des chargements importants et répétés. La façon habituelle de quantifier le chargement au dos des individus est d’estimer le moment qui s’exerce à l’articulation lombo-sacrée (L5/S1). L’estimation de ce moment se fait généralement en laboratoire et nécessite la connaissance de la position et de l’orientation de …

Protecting Cattle Feedyard Workers In The Central States Region: Exploring State, Regional, And National Data On Fatal And Nonfatal Injuries In Agriculture And The Beef Production Sector, Athena K. Ramos, Suraj Adhikari, Risto Rautiainen, Aaron Yoder

Journal of Extension

Working in agriculture can be dangerous. Despite ongoing efforts of Extension, animal production worker safety has not been adequately addressed. We present state, regional, and national counts and rates on fatal and nonfatal injuries in agriculture and animal production using publicly available data from the Bureau of Labor Statistics. We found that animal production had a high number of fatal injuries and a higher rate of nonfatal injuries than the average within agriculture. More needs to be done to protect livestock workers from injury. Extension professionals can play a key role in increasing safety knowledge and changing behaviors.

The Relationship Between Emergency Physicians’ Creative Thinking Preference And Their Risk Of Burnout: An Opportunity To Make A Difference, Naghma S. Khan

Creativity and Change Leadership Graduate Student Master's Projects

The FourSight theory contends that individuals exhibit a preference for the mental operations involved in creative problem solving. The four fundamental mindset preferences measured by FourSight are Clarifiers, Ideators, Developers and Implementers. Individuals can exhibit a peak preference for one, two, or three of these mindsets, or they can show an even distribution of energy across all four creative-thinking preferences. Robust and creative solutions to complex and recurrent problems are only possible if an individual or a team of individuals consciously move through the four stages of problem solving. Creative problem-solving can be taught. The ability to be creative at …
