This report is a rst attempt of formalizing the diagonalization proof technique. We give a strategy how to systematically construct diagonalization proofs: (i) nding an indexing relation, (ii) constructing a diagonal element, and (iii) making the implicit contradiction of the diagonal element explicit. We suggest a declarative representation of the strategy and describe how it can be realized i...

The last few years have seen an opening up of what is considered to be the legitimate terrain of international relations (IR). This move is, for the most part, extremely welcome. Yet, the multiple theoretical and empirical openings in IR since the end of the Cold War have failed to elucidate many of the puzzles, questions and problems posed by the contemporary conjuncture. There are a number of...

Let Θ be an arbitrary variety of algebras and H an algebra in Θ. Along with algebraic geometry in Θ over the distinguished algebra H, a logical geometry in Θ over H is considered. This insight leads to a system of notions and stimulates a number of new problems. Some logical invariants of algebras H ∈ Θ are introduced and logical relations between different H1 and H2 in Θ are analyzed. The pape...

The two main types of law are legislation and precedents. Both types have a corresponding reasoning pattern determining legal consequences: legislation can be applied and precedents followed. The separate modelling of these two reasoning patterns using logical techniques has recently seen considerable progress. About the logical links between the two less is known, although progress has already...

Physician assistants (PAs) have been used for decades in the Canadian military. Now, PAs are being introduced in various clinical settings to provide patient care for the general population. This article reviews major developments in the PA profession across Canada over the last decade. Nearly 541 PAs are employed in Canada or work for a Canadian agency. Growing evidence demonstrates the positi...

A paper previously published in Law and Human Behavior by D. Davis and W. C. Follette (2002) argued that certain "profiling" characteristics commonly admitted into court have little or no probative value. They argued that this is especially likely to be true when the characteristic used as evidence (e.g., having an extramarital affair) is rather common in the population whereas the act in quest...

Foreword Historically the disability and costs associated with mental health problems have been underestimated. This is particularly the case with anxiety disorders, the associated burden of disease now understood to be comparable to other major mental health conditions. Anxiety disorders impose a substantial cost on society and markedly compromise the quality of life for those affected. The Pr...

In this issue... Fundamental east-west synergies in electricity generation and transmission are waiting to be more fully exploited. Doing so would require provinces to rethink their electricity trading relationships with each other and with the United States.

OBJECTIVE To create a mechanism in British Columbia (BC) for youth and families to directly engage with key provincial committees that develop policy and implement service delivery for child and youth mental health. METHOD In 2009, a plan was initiated to increase the involvement and influence of youth and families in research, policy, practices and programs related to child and youth mental ...
