The plan is for us and Sta- tistics to have the top four floors of 215 Huron, connected by a bridge spanning the 3 metres between the 6th floor of Bahen and the 7th floor of 215 Huron. The plan has been a little delayed due to delays in Philosophy’s move out of 215 Huron, as well as the change in administration at the faculty level, but is expected to be completed in the next two years. Progress took place last fall when we obtained the 10th floor of 215 Huron, which now houses several faculty and staff, the dynamics lab, and a large proportion of our graduate students, with a very pleasant graduate student lounge and John Bland Honoured lovely views of the city.

  • A Case Study in the Mobilization of the Canadian Civil Liberties ~Overnent'
    Spies, Lies, and a Commission 53 Spies, Lies, and a Commission: A Case Study in the Mobilization of the Canadian Civil Liberties ~overnent' Dominique ClCment It was unnecessary to set up a Royal Commission to do apolice job, and a job that had already been done by the R.C.M.P. There is no Canadian precedent and no authority for setting up of a Royal Commission to sit in secret. There does not seem to be any authority for the action of the Commission in swearing witnesses to secrecy. The Commission refused to advise witnesses as to their rights, even when requested to do so. In many cases the Commission refused access to counsel at a time when the Commissioners well know that charges would be preferred against the person asking counsel. The Commissioners showed strong political bias and prejudice, and by the procedure they adopted they unfairly handicapped the defence of the ac~used.~ This remonstrance was part of a letter sent to Justice Minister J.L. Ilsley by the Civil Rights Union (Toronto) in February, 1947, and emphasizes what civil libertarians found most abhorrent about the Royal Commission on Espionage. The commission, from February to August, 1946, embarked on one of the most thorough abuses of individual rights ever conducted by an organ of the Canadian state.3 It was armed with extensive powers under the War Measures Act, Oficial SecretsAct and the Public InquiriesAct to determine the extent ofthe Soviet spy ring in Canada revealed by the defection of Igor ~ouzenko.~Coming on the heels of the deportation of Japanese Canadians in 1945-6 and extensive censorship under the Defence of Canada Regulations throughout World War Two (WWII), the commission provided civil libertarians with another powerful issue to remind the public of the vulnerability of individual's civil liberties to state abuse.5 The Royal Commission on Espionage played a key role in stimulating the early civil liberties movement in post-WWII Canada.

  • Matical Society Was Held at Duke Univers
    THE ANNUAL MEETING OF THE SOCIETY The forty-third Annual Meeting of the American Mathe­ matical Society was held at Duke University, Durham, and the University of North Carolina, Chapel Hill, North Carolina, from Tuesday to Thursday, December 29-31, 1936, in conjunc­ tion with the meetings of the Mathematical Association of America. The morning session on Thursday was held at the University of North Carolina and the other sessions at Duke University. In number of papers offered, it was one of the largest of the Annual Meetings. The arrangements as made by the committee, of which Professor J. M. Thomas was chairman and Professors E. T. Browne, W. W. Elliott, J. W. Lasley, and J. H. Roberts were the other local members, were beautifully carried out, and the meeting proved to be one of the most scientifically interesting and socially pleasant in the annals of the Society. At the dinner on Wednesday evening, on motion of Professor T. R. Hollcroft, the Society passed a hearty vote of thanks to the officers of the inviting institutions and to the Committee on Arrangements. Through the generosity of Duke University, rooms in the dormitories of the men's campus were available to the mem­ bers of the two mathematical organizations and their families. The facilities for golf were taken advantage of by several mem­ bers of the Society. On Tuesday evening there was a concert of negro spirituals given under the auspices of Duke University by a negro choir, and on Thursday evening Professor Marston Morse tendered the visitors a delightful piano recital.

  • Reflecting on the Lessons of the Gouzenko Spy Trials
    1 CIVIL RIGHTS IN A TIME OF FEAR: REFLECTING ON THE LESSONS OF THE GOUZENKO SPY TRIALS The fears we cannot climb become our walls. Noah Ben Shea, Jacob the Baker, 1989 1. INTRODUCTION Although we tend to think of civil and human rights as immutable and even sacrosanct, the history of such rights demonstrate that, sadly, the opposite is sometimes true. These rights are public declarations of what a nation believes and cherishes, the moral and ethical framework of a society, but civil rights, in reality, are only protected when we, as a society, decide they are protected. Fear, be it of espionage, or war, or terrorism, can compel us, individually, and as a community, to do things that, in ordinary circumstances, we would never find acceptable. Absolutes become flexible. Examples, in the long shadow of the terrorist attacks of 11 September 2001 on the United States, are easy to find: suspected terrorists are held indefinitely, secret tribunals adjudicate security risks and personal data on everyone is collected. Torture has even been justified, albeit as a last resort. Politicians enact such measures because we let them, because we are all afraid, because draconian measures, in a climate of fear, are what we believe we need. Yet, ironically, even as we demand such measures from our politicians, we simultaneously expect that courts will protect and uphold the very civil rights under threat. We expect judges to resist demagoguery, hysteria, and fear, and coolly and dispassionately dispense justice. But courts are staffed with living, breathing human beings, not legal automatons, and these judges can, just as easily, be caught up in the polemic that national security trumps civil rights in times of fear.

  • C:\My Documents\Angel\Jefferey-Williams
    The 31st Jeffery-Williams Prize Lecture Le 31ème Prix de conférence Jeffery-Williams Citation George Elliott ranks among the very best operator algebraists in the world, a place he shares with two Fields medallists. In addition to being extremely productive, he has been a visionary who has set the subject on a new course. A dramatic conjecture that he made ten years ago suggested a mechanism for classifying a large and important class of C*-algebras. Moreover he established the prototype theorem stimulating a decade of intense searching for more pieces of this puzzle. Despite some initial scepticism, Elliott's program has had some dramatic successes; and it is now clear that his classification scheme is of fundamental importance and applies to a significant part of the conjectured class. George A. Elliott University of Toronto This work has led not only to isomorphism theorems for C*-algebras sharing common invariants, but has also led to constructions that show that many C*-algebras have a special structure that was not imagined a decade ago. In the last few years, Elliott's work has been recognized by many awards, including the CRM/Fields Institute prize, a Connaught Transformative grant from the University of Toronto and a Killam research fellowship. The CMS is pleased to honour him as the winner of this year's Jeffery-Williams prize. George Elliott est sans doute l'un des meilleurs au monde dans le domaine des opérateurs d'algèbre, une place qu'il partage avec deux médaillés Fields. En plus d'être extrêmement productif, il est considéré comme un visionnaire après avoir dirigé le domaine dans une toute nouvelle direction.
