Businesses and governments devote substantial resources to the collection and analysis of survey data concerning the public’s preferences. The possibility of strategic responses to such surveys is analyzed. Consequential and hypothetical surveys are formally defined. For the former the question is posed: what form should strategic behavior take? The particular form is shown to be context depend...

The development of alternative fuelled vehicle technology is a key strategy towards environmental sustainability and improved air quality in cities. Analysis of the role of vehicle technology in fulfilling sustainability targets requires estimates of future vehicle demand. The inability to observe actual car-type preferences for cleaner vehicles has led researchers to the development of stated ...

Stated choice experiments are often used in transportation studies for estimating and forecasting behavior of travelers, road authorities, etc. This kind of experiments rely on underlying experimental designs. Whilst orthogonal designs are mainstream for practitioners, many researchers now realize that so-called efficient designs are able to produce more efficient data in the sense that more re...

It has been argued that epistemic contextualism faces the so-called factivity problem and hence cannot be stated properly. The basic idea behind this charge is that contextualists supposedly have to say, on the one hand, that knowledge ascribing sentences like “S knows that S has hands” are true when used in ordinary contexts while, on the other hand, they are not true by the standard of their ...

Our objective is to develop a unifying framework for the incorporation of different types of survey data in individual choice models. We describe statistical methodologies that combine multiple sources of data in the estimation of individual choice models and summarize the current state of the art of data combination methods that have been used with market research data. The most successful app...

PURPOSE To assess current education, practices, attitudes, and perceptions pertaining to ethics and professionalism in medical physics. METHODS A link to a web-based survey was distributed to the American Association of Physicists in Medicine (AAPM) e-mail membership list, with a follow-up e-mail sent two weeks later. The survey included questions about ethics/professionalism education, direc...
