The paper is concerned with supporting natural patterns of scientific collaboration in Access Grid environments. We reveal that no current approach to Access Grid allows dynamic session invocation within on-going Access Grid sessions nor workflow driven session triggering among users involved in that workflow. A model for a lightweight signaling architecture integrated within Access Grid is pro...

A recent Ontario arbitral award is reshaping the way employers and employees must approach the legal duty to accommodate employees with disabilities in the workplace. Entrenched in both federal and provincial human rights legislation, the duty to accommodate imposes a legal obligation on employers to accommodate employees with disabilities unless such accommodation would cause undue hardship on...

We analyze the distribution of ∑ m i=1 vixi where x1, . . . ,xm are fixed vectors from some lattice L ⊂ R (say Z) and v1, . . . , vm are chosen independently from a discrete Gaussian distribution over Z. We show that under a natural constraint on x1, . . . ,xm, if the vi are chosen from a wide enough Gaussian, the sum is statistically close to a discrete Gaussian over L. We also analyze the cas...
