Evaluation of the ArtsSmarts Strategy: Impacts and Sustainability
The purpose of this report is to provide: 1) an analysis of findings from a survey, interviews and focus groups regarding ArtsSmarts projects funded by the J.W.McConnell Family Foundation across Canada in 2002-2003 and 2) to support advocacy work to obtain long term funding and support for sustainability of the ArtsSmarts approach. The report focuses on the impact of the projects on students, the education system, the community and the arts community addressing key "spheres of Influence" in the educational system
Physics at TESLA
The physics at a 500-800 GeV electron positron linear collider, TESLA, is
reviewed. The machine parameters that impact directly on the physics are
discussed and a few key performance goals for a detector at TESLA are given.
Emphasis is placed on precision measurements in the Higgs and top sectors and
on extrapolation to high energy scales in the supersymmetric scenario.Comment: Talk presented at Lake Louise Winter Institute 2001. 7 pages, 2

Government of Canada Yield-Curve Dynamics, 1986-2003
A database of historical Government of Canada zero-coupon yield curves developed at the Bank of Canada is introduced in this article, which also includes an initial statistical analysis of the behaviour and evolution of the zero-coupon interest (spot) rates over the full period and two distinct subperiods. Specific areas of interest include the evolution of the levels of key interest rates and yield-curve measures over the sample as well as daily changes in the key interest rates and the yield-curve measures; the identification of a relatively small number of factors that drove the evolution of the yield curve; and the total returns that would have been realized by holding bonds of different maturities for a given holding period.
Tracking Global Corporate Citizenship: Some Reflections on ‘Lovesick' Companies
This paper provides an outline of some of the issues I am dealing with in connection to a research project being undertaken on Global Corporate Citizenship (GCC). This research is in its early stages so what is provided here is preliminary and designed to raise rather more issues than it solves. In particular, I am concerned to deal with what it might mean for companies to be described, or to describe themselves, as Global Corporate Citizens. In the general literature on corporate responsibility there is a move away from companies being described, or describing themselves, as Corporately Socially Responsible (CSR) to them re-describing themselves as Global Corporate Citizens (GCC). I want to ask what is involved in this (self)description as ‘citizens'? Can citizenship be applied first to companies and then extended into the global arena in which they operate? When looking at the actual practices of companies that claim to be either simply socially responsible or more recently corporate citizens , there is not much difference between them. Much the same ‘content', as it were, in terms of the claims to what they are doing or should do, adheres under both titles. So is it merely a matter of words? Does it make any difference that on the one had they claim to be socially responsible or on the other to be global citizens? I will argue that this is a very significant change in terminology that is having, and will continue to have, significant affects that need to be analysed and appreciated. To explore these implications, the following analysis situates GCC in a wider framework of the progressive juridicalization and constitutionalization of the international arena more generally.
Precision GMSB at a Linear Collider
We simulate precision measurements of gauge-mediated supersymmetry breaking
(GMSB) parameters at a 500 GeV e+e- linear collider in the scenario where a
neutralino is the next-to-lightest supersymmetric particle. Information on the
supersymmetry breaking and the messenger sectors of the theory is extracted
from the measured sparticle mass spectrum and neutralino lifetime.Comment: LaTeX + sprocl.sty + epsf.sty, 6 pages, 3 figures (5 eps files
Extracting GMSB Parameters at a Linear Collider
Assuming gauge-mediated supersymmetry breaking, we simulate precision
measurements of fundamental parameters at a 500 GeV e+e- linear collider in the
scenario where a neutralino is the next-to-lightest supersymmetric particle.
Information on the supersymmetry breaking and the messenger sectors of the
theory is extracted from realistic fits to the measured mass spectrum of the
Minimal Supersymmetric Model particles and the next-to-lightest supersymmetric
particle lifetime.Comment: 6 pages, LaTeX + epsf.sty, 3 figure
Ab initio R-matrix calculations of e+-molecule scattering
The adaptation of the molecular R-matrix method, originally developed for electron-molecule collision studies, to positron scattering is discussed. Ab initio R-matrix calculations are presented for collisions of low energy positrons with a number of diatomic systems including H2, HF and N2. Differential elastic cross sections for positron-H2 show a minimum at about 45 deg for collision energies between 0.3 and 0.5 Ryd. The calculations predict a bound state of positronHF. Calculations on inelastic processes in N2 and O2 are also discussed
Analysis of the transaction costs and administration benefits associated with Behind The Label
Compliance with government regulations represents a cost to business operations. Of all compliance activities, compliance with taxation regulations and legislation constitutes a significant proportion of business expense.
Estimates obtained in this study by Phillip O\u27Neill and Grahame O\u27Leary suggest that compliance with licensing and other arrangements of the proposed Ethical Clothing Trades Act account for less than five per cent of total compliance costs
Acute drug effects on habitual and non-habitual responding in crossed high alcohol preferring mice
RATIONALE:
Drug reward plays a central role in acquiring drug-seeking behavior. However, subjects may continue using drugs despite negative consequences because self-administration becomes habitual, and divorced from outcome values. Although a history of drug and alcohol use expedite habit acquisition, and in spite of the fact that self-administration leads to intoxication, the acute effects of drugs on habitual responding are not well understood.
OBJECTIVES:
We sought to observe how acute ethanol and amphetamine affect the balance between habitual and goal-directed behavior, as measured by a fluid-reinforced operant conditioning task.
METHODS:
Selectively bred crossed high-alcohol-preferring (cHAP) mice were trained on an operant conditioning task reinforced on a variable interval schedule with 1% banana solution, which was subsequently devalued via LiCl pairing in half the animals. Ethanol (1.0 g/kg), amphetamine (2.0 mg/kg), or saline was administered prior to a post-devaluation test.
RESULTS:
Overall, mice showed habitual behavior, but when divided into high- or low-responding groups based on training response rates, saline-treated, low-responding animals devalued, while saline-treated high-responding animals did not. Furthermore, amphetamine elicited devaluation even in high-responding animals, while ethanol prevented devaluation even in low-responding animals.
CONCLUSIONS:
These data show that ethanol shifts animals toward behaving habitually. This may illuminate why alcohol-intoxicated individuals display impaired judgment about the relative merits of drinking, and potentially serve as a mechanism by which intoxicated subjects resume previously devalued behaviors, such as comorbid drug use. These findings also show that high variable interval response rates facilitate a shift from goal-directed to habitual behavior
