  • Canada has a rich history in the theory and development of the field of health promotion. Over 25 years ago, in 1974, the Canadian government produced the first government policy document that identified health promotion as a national strategy. The document, which came from the national Health Minister, was entitled A New Perspective on the Health of Canadians (Lalonde, 1974). It led the way for other governments to produce similar documents, and to many western countries embracing the ideas and ideals of health promotion.(omitted)

  • The accelerated failure time model or accelerated life model relates the logarithm of the failure time linearly to the covariates. The parameters in the model provides a direct interpretation. In this paper, we review some newly developed practically useful estimation and inference methods for the model in the analysis of right censored data.

  • This paper introduces a multilevel item-response-theory (IRT) model as a unifying model for hypothesis testing using legislative voting data. This paper shows that a probit or logit model is a special type of multilevel IRT model. In particular, it is demonstrated that, when a probit or logit model is applied to multiple votes, it makes unrealistic assumptions and produces incorrect coefficient estimates. The advantages of a multilevel IRT model over a probit or logit model are illustrated with a Monte Carlo experiment and an example from the U.S. House. Finally, this paper provides a practical guide to fitting this model to legislative voting data.

  • This paper investigates how public opinion has affected the United States Senate's votes on arms control treaties. Applying multilevel modeling with post-stratification to national polls, this paper produces estimates of state-level opinion on both the New Strategic Arms Reduction Treaty of 2010 and the Comprehensive Test Ban Treaty of 1999. Using these estimate, this paper examines the relationship between public opinion and the Senate's votes on the treaties. This paper finds that the influence of public opinion was mostly significant but indirect. These findings indicate that some version of the delegate model of representation is more applicable to foreign policy making in Congress.
