Canadian prime ministers in the house of commons: Patterns of intervention

This paper explores the parliamentary activity of six Canadian prime ministers from St Laurent to Mulroney. Employing Hansard, each parliamentary utterance by a prime minister from 1949 to 1993 has been coded into one of four categories: answers to questions, speeches delivered, statements made and other interventions. Voting records have also been coded. Employing this database, the analysis compares and contrasts the prime ministers in terms of their political personalities and explores the overall scope and character of prime‐ministerial activism in the House throughout the past 40 years. Canadian profiles are compared with already existing British data in order to test generalisations concerning the diminishing presence of prime ministers in parliaments in Canada and Britain.

Portable high‐resolution automated 3D imaging for footwear and tire impression capture

The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners.
