Harry Kiefte (1942–1997) was born in Amsterdam and moved to Toronto at an early age where he completed his formal education. His Ph.D. research was in the field of electron paramagnetic resonance under J.S.M. Harvey at the University of Toronto. He then completed two years of postdoctoral study with B.P. Stoicheff at the same institution where he participated in the pioneering work that led to the recording of the first Brillouin spectra from single crystals of rare-gas solids and the consequent determination of the elastic constants for these materials. It was the technique of Brillouin spectroscopy, and its application to the determination of the elastic properties of a wide range of crystalline materials, that engaged his interest and very considerable talents for the remainder of his career at the Department of Physics, Memorial University, where he accepted a faculty position in 1973. At the time of his death, at the relatively young age of 54, his name appeared as author or co-author on approximately 90 publications. Included among the co-authors were four graduate students whose research was devoted to ice-related studies. It is this significant contribution to our knowledge of the elastic properties of ice that will be reviewed in this paper. PACS No.: 62.20Dc

The late Taro Takahashi earned a particularly well-deserved reputation for his research at Lamont Geological Observatory on carbon dioxide and its transfer between the atmosphere and the oceans. However, his accomplishments in Mineral Physics, the field embracing the high-pressure–high-temperature properties of materials, has received less attention in spite of his major contributions to this emerging field focused on the interiors of Earth and other planets. In 1963, I was thrilled when he was offered a faculty position in the Geology Department at the University of Rochester, where I had recently joined the faculty. Taro and I worked together for the next 10 years with our talented students exploring the blossoming field just becoming known as Mineral Physics, the name introduced by Orson Anderson and Ed Schreiber, who were also engaged in measuring physical properties at high pressures and temperatures. While their specialty was ultrasonic velocities in minerals subjected to high pressures and temperatures, ours was the determination of crystal structures, compressibilities, and densities of such minerals as iron, its alloys, and silicate minerals, especially those synthesized at high-pressure, such as silicates with the spinel structure. These were materials expected to be found in the Earth’s interior and could therefore provide background for the interpretation of geophysical observations.

The Editorial Board of Renaissance Quarterly is most kindly continuing its tradition in Renaissance News by allowing me to publish the third supplement to the Catalogue of Italian Plays 1500-1700 in theUniversity of Toronto Library (University of Toronto Press, 1961). Previous supplements appeared in RN16 (1963), 298-307, and 19 (1966), 219-228. The plays listed below illustrate a wide range of theatrical tastes, from Latin and Italian passion plays, medieval in tradition, to the later dominant vogue for musical dramas. In editions of the latter it became customary early in the seventeenth century to record architects, costumers, and performers, so that the printed plays are a valuable source for stage history. Scenery for four of these dramas was designed by Ferdinando and Francesco Galli di Bibbiena, then at the outset of their careers.

The Lister Symposium was held primarily to review the latest concepts of the mechanisms of bacterial infections, and to highlight the research being carried out currently in Toronto and in Canada. The inclusion of several speakers from outside of Toronto added a strong foundation for the meeting.A wide range of topics were addressed and these demonstrated the many areas of research being pursued to better understand the pathogenesis of microbial infections. By drawing together physicians, scientists, and students from a variety of disciplines, it was hoped that the Lister Symposium would contribute, not only to our knowledge of medicine and science in this field, but also to the continued local and national cooperation required for first-class investigative research.This meeting was the first of its kind held under the auspices of the Department of Surgery at the University of Toronto, demonstrating its commitment to research and interdepartmental collaboration. We are most grateful to Professor Bernard Langer, Chairman of the Department of Surgery, for his support in this regard. The assistance of our sponsors and the Continuing Medical Education Office facilitated a wide outreach and enabled recognition of the course and accreditation for Canadian and American Medical participants. It is hoped that this material will provide a useful reference for future developments in the field.

Knowledge of the mechanisms of assembly of amyloid proteins into aggregates is of central importance in building an understanding of neurodegenerative disease. Given that oligomeric intermediates formed during the aggregation reaction are believed to be the major toxic species, methods to track such intermediates are clearly needed. Here we present a method, electron paramagnetic resonance (EPR), by which the amount of intermediates can be measured over the course of the aggregation, directly in the reacting solution, without the need for separation. We use this approach to investigate the aggregation of α-synuclein (αS), a synaptic protein implicated in Parkinson’s disease and find a large population of oligomeric species. Our results show that these are primary oligomers, formed directly from monomeric species, rather than oligomers formed by secondary nucleation processes, and that they are short-lived, the majority of them dissociates rather than converts to fibrils. As demonstrated here, EPR offers the means to detect such short-lived intermediate species directly in situ. As it relies only on the change in size of the detected species, it will be applicable to a wide range of self-assembling systems, making accessible the kinetics of intermediates and thus allowing the determination of their rates of formation and conversion, key processes in the self-assembly reaction.

In order to establish a large sample of the standardization of the norm of the National College Students’ physical exercise behaviour, this study uses the change scale of college students physical exercise behaviour, and a large range of survey of the university students physical exercise behaviour. According to the statistical analysis of the data obtained by the national college students physical exercise behaviour’ change standard norm, it can provide a reliable, effective and valuable reference for the study of college students physical exercise behaviour. In the cross theoretical model, the lack of the determination of the stage of the change, especially after a wide range of survey, produces the precise analysis and interpretation. After a large scale of the investigation, this study not only has a simple region to change the stage and change process, but also to find the corresponding relationship between them, as well as the different stages of the weight of the change process.

The three years that have elapsed since the Harvard meeting of the Union have witnessed steady progress in the determination of radial velocities. While the three large Pacific Coast Observatories have naturally been able to make the greatest additions to radial velocity work, the Yerkes Observatory, the Simeiz Observatory and the Observatory of the University of Michigan have also made valuable contributions. It is a pleasure to report that there will soon be three major accessions to the list of observatories capable of determining radial velocities. The David Dunlap Observatory of the University of Toronto with its 74-inch telescope, which should be in operation soon after the meeting, will have radial velocities as a prominent feature of its programme. The McDonald Observatory of the University of Texas with an 80-inch telescope now under construction should be ready to commence operations in 1936 and will undertake an extensive radial velocity programme. The Radcliffe Observatory at Oxford has now been granted permission by the Courts to remove to Pretoria, South Africa, and will establish there a 74-inch reflecting telescope, which will also be largely employed in the determination of the urgently needed radial velocities of the southern stars fainter than 5.5 visual magnitude. The Commission may, I believe, congratulate itself that substantial assistance in the preliminary steps leading to this permission of removal was provided by our action at the last meeting in presenting a resolution to the Union, duly passed by the General Assembly, pointing out the urgent need for additional radial velocities in the southern sky, and strongly supporting the project of the Radcliffe Observatory to establish a large telescope at Pretoria.

Dr Bellingham completed his medical school and anesthesiology residency at Western University. He followed this with a fellowship in Chronic Pain Management at the University of Toronto, with a focus on interventional pain management using fluoroscopy and ultrasound guided techniques. Dr Bellingham returned to Western University to work in the Department of Anesthesia and Perioperative Medicine in his capacity as an anesthetist and as a chronic pain specialist. Here at Western, he directs the Pain Clinic at St. Joseph’s Health Care and also played a key role in the development of Canada’s first Pain Medicine residency program. We had an opportunity to chat with Dr Bellingham and discuss a wide range of topics including his choice of career path, the Pain Medicine residency program, and other pain medicine topics in the context of the current opioid epidemic.

Nutrient profiling (NP) models are useful tools for objectively and transparently quantifying the nutritional quality of packaged foods and beverages. Many NP models incorporate ingredients beneficial for health (e.g., fruits, vegetables, nuts, legumes (FVNL)) in addition to less healthful nutrients or components, assigning points based on the proportion of the product that contains FVNL ingredients. However, with food labelling in most countries lacking mandatory quantitative ingredient declarations (QUIDs), there is potential for the estimation of FVNL points to be ambiguous and inconsistent. The purpose of this article was to describe the development and application of methodology for estimating FVNL points for products without QUIDs, based on the position of FVNL components within the ingredients list. Using this method, FVNL points were calculated for packaged foods and beverages in the University of Toronto Food Label Information Program 2017 database (n = 17,337). Distributions of FVNL points were examined overall and by food category. This study provides evidence of the feasibility of this method in distinguishing between products with differing amounts of FVNL ingredients. This method will be valuable for researchers and policymakers in ensuring consistent, objective and reproducible estimations of FVNL points—and consequently, assessments of product healthfulness—for food supplies without QUIDs.

Philosophers need not be located in departments of philosophy in order to be worth reading. Here is a work eminently warranting attention from professional philosophers, perhaps all the more because its author, William Leiss (who earned a Ph.D. in philosophy in 1969 but has never held a formal faculty position in that subject) writes from a variety of alternative perspectives. His first academic position was in Political Science and Environmental Studies at the University of Regina. From there he travelled to York University as Associate Professor of Environmental Studies, taking a year out to serve as Associate Professor of Sociology at the University of Toronto before returning to York and again adding Political Science to his duties in Environmental Studies. Since 1980 he has been Professor of Communication at Simon Fraser University. Although originally a New Yorker, with academic credentials from south of the border, he now writes with distinctly Canadian examples, outlook and style.

The last meeting on the determination of radial velocities was held at the University of Toronto, June 20 - 2A 1966, eighteen years ago. Five of the participants of this meeting were present at that meeting; Abt, Batten, Bertiau, Fehrenbach and Griffin. The lead article was “Photoelectric Measurements of Radial Velocities” by Griffin, followed by “Radial Velocities From Image Tube Spectra” by Rubin, Ford and Christy. These were the major new methods of determining radial velocities.This meeting was planned to discuss the major advances made in the accuracy with which radial velocities can now be measured, and the applications of these methods to astronomical problems. I made a formal proposal at the Commission 30 meetings in Patras, Greece, to hold such a meeting in 1984 and the members of the commission ratified the idea. Subsequently, proposals were made to the Executive Committee of the IAU for sponsorship and to the National Science Foundation for financial support. Union College provided the first financial support and agreed to act as host for the meeting. The result of these activities is the presence of all of you in Schenectady for this meeting. I trust that it will be a productive meeting and I wish you all success with your deliberations.
