New empirical evidence and statistical derivations of Benford's Law have led to successful goodness-of-fit tests to detect fraud in accounting data. Several recent case studies support the hypothesis that fabricated data do not conform to expected true digital frequencies.

This is a panel session focused on the applications of Human Factors to real world problems in architectural design. Five representatives from various design & research professions will present recent case studies of theirs, and examine the contribution that Human Factors made to these projects. The diversity of their examples shows the usefulness and importance on integrating concerns for the human user into plans for the built environment.

A common thread throughout much of Canada’s current theatrical output is that it asks audiences to think deeply about themselves and their connection to the material. Working with the idea that theatre has an important social and educational impact, my essay examines the need to set boundaries for theatre content. These boundaries are meant to function as a set of guidelines for managing controversial artistic choices, especially in a culture where artistic freedom and productive controversy are at stake. Some of the criteria I have developed for how to set boundaries include: how the work represents its subjects; what Canadians see as taboo; personal limitations individuals set for themselves; and, contentious timing. My research examines recent case studies, starting with Robert Lepage’s Kanata, which aimed to discuss Canada’s settler history, however, was cancelled in Canada after Indigenous artists and activists wrote an open letter concerning the lack of Indigenous presence in the cast and production team. I then move to an example that challenges my proposed model with Prom Queen: The Musical, a play about an Ontario student and his boyfriend battling the Catholic school board to go to prom together. I argue that although the play may not represent the values of the school board, adequate representation of the board’s ideals should be disregarded due to their anti-LGBTQ2+ beliefs. Through these examples and more, my research found that there are certain boundaries that should not be crossed in theatre. However, determining where these boundaries are situated remains in constant negotiation.

Size-selected Wn clusters can be deposited firmly on a graphite (0001) surface using a novel technique, where the positive ions (of the same metal atom species) embedded on the graphite surface by ion implantation, act as anchors. The size selected metal clusters can then soft land on this anchored surface m [Hayakawa et al., 2009]. We have carried out a systematic theoretical study of the adsorption of Wn (n = 1-6) clusters on anchored graphite (0001) surface, using state-of-art spin-polarized density functional approach. In our first-principles calculations, the graphite (0001) surface has been suitably modeled as a slab separated by large vacuum layers. Wn clusters bond on clean graphite (0001) surface with a rather weak Van-der-Waals interaction. However, on the anchored graphite (0001) surface, the Wn clusters get absorbed at the defect site with a much larger adsorption energy. We report here the results of our first-principles investigation of this supported Wn cluster system, along with their reactivity trend as a function of the cluster size (n).

This article reviews the use of photographs as data within the social sciences as well as defining related terminology used over the past century. It then examines the use of photos as stimuli for talking about health settings before presenting three recent case studies where photo-interviewing has been used successfully in health evaluation and research. Advantages and limitations of the method are considered.

AbstractPt-Sc alloys with the γ-γ′ microstructure are proposed as a basis for a new generation of Pt-based superalloys for ultrahigh-temperature applications. This alloy system was identified on the basis of first-principles calculations. Here we discuss the prospects of the Pt-Sc alloy system on the basis of calculated elastic properties, phonon spectra, and defect formation energies.
