Recently, several innovative tools have found their way into mainstream use in modern development environments. However, most of these tools have focused on creating and modifying code, despite evidence that most of programmers’ time is spent understanding code as part of maintenance tasks. If new tools were designed to directly support these maintenance tasks, what types would be most helpful?...

We present a new algorithm for solving basic parametric constructible or semi-algebraic systems like C = {x ∈ C, p1(x) = 0, , ps(x) = 0, f1(x) 0, , fl(x) 0} or S = {x ∈ R, p1(x) = 0, , ps(x) = 0, f1(x)> 0, , fl(x)> 0}, where pi, fi ∈Q[U , X], U = [U1, , Ud] is the set of parameters and X = [Xd+1, , Xn] the set of unknowns. If ΠU denotes the canonical projection onto the parameter’s space, solvi...

Longstanding concerns about quality care provision, specifically in the area of long-term care, have prompted calls for changing the culture of care to reflect more client-driven and relationship-centred models. Despite an increase in culture change initiatives in both Canada and the United States, there is insufficient information about the theories and approaches that guide culture change. Th...

This is the first time, in a formal structured way, I've been asked to speak before a group of academicians on this set of issues. It is a great honor to be invited to speak on behalf of one of the two “culture’ mentioned in the commentary by C.P. Snow (1905–1980) [1]. It is also a great challenge to be so called upon to speak for an entire “culture.” Of necessity, my comments were created from...

Background and Objectives: In recent decades medical errors have become a major issue for scientific investigation to avoid potential harmful failures threatening patients’ health and safety. Developing risk management culture has been considered not only to play an important role in detecting and coping effectively with such errors but also lead to high level ...
