Thomas Kuhn and Science Education: Learning from the Past and the Importance of History and Philosophy of Science.

Beginning 60 years ago, Thomas Kuhn has had a significant impact across the academy and on culture more widely. And he had a great impact on science education research, theorising, and pedagogy. For the majority of educators, the second edition (1970) of his (Kuhn, 1970a) articulated the very nature of the science, the discipline they were teaching.

Mario Bunge (1919-2020): Physicist, philosopher, champion of science, and citizen of the world.

Mario Bunge, the centenarian Argentine/Canadian physicist/philosopher passed away in the loving company of his wife Marta and children Eric and Silvia on February 24, 2020 in Montréal, Ontario. This memoriam reviews his life and work, particularly his contributions to physics and philosophy of science.

Development and Validation of the Foot Union Scoring Evaluation Tool for Arthrodesis of Foot Structures.

Reliable evaluation of osseous consolidation after pedal arthrodesis can be difficult, and the presence or absence of radiographic healing often dictates care. Plain radiographs remain the mainstay imaging tool owing to their cost, efficiency, and low radiation exposure. Applying radiographic parameters that can reliably determine osseous healing is essential.

Radiographic Union Scoring Scale for Determining Consolidation Rates in the Calcaneus.

The reliable evaluation of osseous consolidation after hindfoot osteotomy can be difficult. Concomitant hindfoot osteotomies often dictate the advancement of weightbearing, and radiographs are the mainstay imaging tool owing to cost, efficiency, and radiation exposure. Understanding the radiographic parameters that can be used to reliably determine osseous healing is paramount.
