Internationally, illegal drug use remains a major public health problem. In response, many countries have begun to shift their illegal drug policies away from enforcement and towards public health objectives. Recently, both the Global Commission on Drug Policy and the Supreme Court of Canada have endorsed this change in direction, supporting empirically sound illegal drug policies that reduce c...

In Part I of this article, which appeared in last month's AJOI', AOI'A President Robert K. Bing examined the founding principles of occupational therapy developed and published in 1925, and offered comments from some pioneering occupational therapists that helped determine how the principles were enacted in practice. This month in Part II Bing continues with more comments from the profession's ...

To determine what the speaker in a cooperative dialog meant with his assertion, on top of what he explicitly said, it is crucial that we assume that the assertion he gave was optimal. In determining optimal assertions we assume that dialogues are embedded in decision problems (van Rooij, 2003) and use backwards induction for calculating them (Benz, 2006). In this paper we show that in terms of ...

In circumstances when a variable in a program has an incorrect value the process of debugging it is often a process about discovering the history of that variable, or rather the ancestry of the value that it contains. In this paper we propose a new technique for debugging that revolves around being able to trace back through the history of a particular variable or variables that it depends upon...

We consider the following secretary problem: items ranked from 1 to n are randomly selected without replacement, one at a time, and tòwin' is to stop at an item whose overall rank is less than or equal to s, given only the relative ranks of the items drawn so far. Our method of analysis is based on the existence of an imbedded Markov chain and uses the technique of backwards induction. In princ...

A Common Interest game is a game in which there exists a unique vector of payoffs which strictly Pareto-dominates all other payoffs. We consider the undiscounted repeated game obtained by the infinite repetition of such an n-player Common Interest game. We restrict supergame strategies to be computable within Church's thesis, and we introduce computable trembles on these strategies. If the trem...
