Does Facial Physiognomy In The Context Of Anoccupational Safety And Health Message Predict Outcomes?, Ian Parker

Theses: Doctorates and Masters

Physiognomy, the practice of looking to another person’s outward facial appearance to unmask the inner character of that person, has had a diverse historical impact within art, medicine, theology, anthropology, law, criminology, political history, psychology, psychiatry, and popular culture, since it was conceptualised in Greece during the 5th and 4th centuries B.C (Physiognomy, 1999-2009, 2009a). Aristotle, the prominent Greek philosopher, penned many chapters on physiognomic properties and touched upon strength/weakness, genius/stupidity, and other trait characteristics and their opposites in so far as such characteristics were associated with facial form (Physiognomy, 2006, 2009b).

In more modern times, facial recognition and evaluation …

Effects Of Motion Segment Simulation And Joint Positioning On Spinal Loads In Trunk Musculoskeletal Models, F. Ghezelbash, A. H. Eskandari, A. Shirazi-Adl, N. Arjmand, Z. El Ouaaid, A. Plamondon

Études primaires

Musculoskeletal models represent spinal motion segments by spherical joints/beams with linear/nonlinear properties placed at various locations. We investigated the fidelity of these simplified models (i.e., spherical joints with/without rotational springs and beams considering nonlinear/linear properties) in predicting kinematics of the ligamentous spine in comparison with a detailed finite element (FE) model while considering various anterior-posterior joint placements. Using the simplified models with different joint offsets in a subject-specific musculoskeletal model, we computed local spinal forces during forward flexion and compared results with intradiscal pressure measurements. In comparison to the detailed FE model, linearized beam and spherical joint models failed to …

The Effect Of Wearing A Lumbar Belt On Biomechanical And Psychological Outcomes Related To Maximal Flexion-Extension Motion And Manual Material Handling, Ali Shahvarpour, Richard Preuss, Michael J.L. Sullivan, Alessia Negrini, Christian Larivière

Études primaires

Workers with low back pain (LBP) may benefit from wearing a lumbar belt (LB), but the biomechanical and psychological mechanisms involved are not fully understood. Two types of flexible LB (extensible and non-extensible) were compared to a control condition (no LB) regarding pain-related (pain, fear of pain and catastrophizing) and biomechanical (range of motion – ROM) outcomes related to two tasks: maximal trunk flexion-extension and manual material handling. Healthy controls and participants with LBP were tested. During both tasks, the two LBs reduced the lumbar ROM in participants with LBP in the same way as healthy controls. This was observed …

Reaction To Safety Equipment Technology In The Workplace And Implications: A Study Of The Firefighter’S Hood, Brian W. Ward

The Qualitative Report

In the 1990s the firefighter’s hood became a standard article of safety equipment worn by municipal firefighters, eliciting a negative reaction among many of these firefighters. I used data from interviews with 42 firefighters to explain why this reaction occurred. Data analysis revealed that negative reactions ultimately stemmed from the hood’s disruption of autonomy, repudiation of the complex mental and physical skill needed to perform tasks required of firefighters, and hindrance in negotiating the life-threatening environment created by a fire. These findings indicate that when introducing new safety equipment technology to emergency response workers, their reaction to this equipment, and …
