Occupational Outliers: Stochasticity and Determinism in Occupational Biomechanics
نویسندگان
چکیده
In the subset of tasks deemed occupational, which can be rather inclusive depending on the definition, multiple sources of variability combine to complicate work task analyses and occupational design approaches, but are not always considered. Focusing on physical ergonomics, three major umbrella categories of occupational variability are: 1) variability in task performance – i.e. how a person performs a specified task; 2) variability in tissue response– i.e. how different persons are affected by common task requirements; and 3) variability in exposure – i.e. how different tasks or subtasks have different requirements. These sources interact to produce many potential injury or overexposure scenarios.

This paper describes occupational biomechanics as an evolving body of knowledge that has required not only a sophisticated development of fundamental biomechanical principles and human failure data, but also has required epidemiological information to enable a more complete understanding of how certain types of musculoskeletal injuries can be caused by specific physical work requirements. It al...
متن کاملState of science: occupational slips, trips and falls on the same level *
Occupational slips, trips and falls on the same level (STFL) result in substantial injuries worldwide. This paper summarises the state of science regarding STFL, outlining relevant aspects of epidemiology, biomechanics, psychophysics, tribology, organisational influences and injury prevention. This review reaffirms that STFL remain a major cause of workplace injury and STFL prevention is a comp...
متن کاملSpatial scale affects the relative role of stochasticity versus determinism in soil bacterial communities in wheat fields across the North China Plain
BACKGROUND The relative importance of stochasticity versus determinism in soil bacterial communities is unclear, as are the possible influences that alter the balance between these. Here, we investigated the influence of spatial scale on the relative role of stochasticity and determinism in agricultural monocultures consisting only of wheat, thereby minimizing the influence of differences in pl...
