Occupational therapy's oversight: How science veiled our humanity.

Background: Occupational therapy's connection to positivist science predates the profession's formal beginning, with important contributing knowledge sources coming from mathematics, physics, psychology, and systems theory. While these sources of objective knowledge provide a rational, defendable position for practice, they can only explain a portion of what it means to exist as an occupational being.

Aims/objectives: This article aims to reveal some of the history of science within occupational therapy and reveal the subjective, ontological nature of doing everyday activities that the profession's preoccupation with positivist science has obscured.

The making of occupation-based models and diagrams: History and semiotic analysis.

Background.: Models provide a structure for organizing knowledge and facilitating learning and are upheld by occupational therapy as epitomizing the cornerstones of its practice.

Purpose.

The unsustainability of occupational based model diagrams.

Occupation-based models are generic explanations of occupational engagement. Their associated diagrams are conceptual tools that represent the key concepts and their interrelationships, which have withstood substantial shifts in the profession's knowledge base and scope over the last 30-40 years. We aim to bring into question the sustainability of the diagrams used to represent models.
