The philosopher Peter Winch (1957) argued that the history of a subject is best written by a practitioner of that subject. This is ably demonstrated by this volume: Wendy Leeds-Hurwitz has assembled a group of high-profile contributors who discuss the emergence and consolidation of particular Language & Social Interaction (LSI) programs at various universities. This is a history of LSI in the United States written by participants in these programs, in their (then) roles of graduate students or faculty members. The result is a collection of enlightening, fascinating, and brilliant essays that focus upon the development, formulation, and transmission of ideas.

Purpose — The research was designed to explore people's willingness/ability to understand complex road user charges. However, the results raise issues about respondent engagement and ecological validity and so have important implications for questionnaire practice.

Methodology — Computer-based experiments administered in the United Kingdom and Germany gathered respondents' estimates of road user charges along with their response latencies, personal characteristics, acceptance of road charging, assessments of task complexity and attitudes to analytical tasks.

Findings — The results demonstrate questionnaire learning effects and show the effect of personal characteristics on the accuracy and speed of questionnaire completion. The tendency of males, younger people and students to complete the task more quickly is interesting as is the fact that fewer and smaller errors were made by participants who claimed to gain satisfaction from completing a task which has involved mental effort. Engagement was seen to vary with personal characteristics, attitudes to decision making, task complexity and acceptance of the policy being tested. A key finding is that disengagement was more evident among participants who were broadly supportive of road charging than among those who were not.

Implications — The findings have important implications for the design of data collection exercises and for the interpretation of resulting data. It is concluded that repeated choice experiments are an inappropriate source of data on responses to unfamiliar circumstances. The collection of data on response latencies and the inclusion of questions on respondents' attitudes to task completion is a strongly recommended addition to standard questionnaire practice. The extent to which disengagement in an experimental context is, or is not, indicative of real-world behaviour is an important and urgent subject for further research.

Did the expansion of democratic institutions play a role in determining central government spending behavior in the 19th and 20th centuries? The link between democracy and increased central government spending is well established for the post-Second World War period, but has never been explored during the first “wave of democracy” and its subsequent reversal, that is 1870–1938. The main contribution of this paper is the compilation of a dataset covering 24 countries over this period to begin to address this question. Utilizing various descriptive techniques, including panel data regressions, we explore correlations between central government spending and the institutional characteristics of regimes. We find that the data are consistent with the hypothesis that democracies have a broader need for legitimization than autocracies as various measures of democracy are associated with higher central government spending. Our results indicate that the extension of franchise had a slight positive impact on central government spending levels, as did a few of the other democracy variables. We also find that early liberal democracies spent less and monarchies more than other regimes; debt increases spending; and participation in the Gold Standard reduced government spending substantially.

Despite the massive social benefits that the car has brought, it has become evident that the current mobility system is undermining the benefits it creates with substantial air quality problems, inactive lifestyles, deaths and injuries from accidents and major contributions to the global climate change challenge. The introduction of smart mobility innovations, in promising to challenge the existing regime of automobility may be a major policy opportunity, and also provide a source of new economic opportunity. However, it is far from clear that these opportunities will be recognized or, even where they are, realized due to the complexities of steering any transition in the mobility system.

This book sets out how we should understand the challenge of governing the smart mobility transition and, in this introductory chapter we set out the key arguments and contributions of each part of the book for addressing these challenges. The first section of the book focuses on how the role of the government is challenged by the growing network of actors and the new resource interdependencies that emerge from smart mobility. How these challenges come to be recognized and resolved is itself a critical part of the governance process as explored in the second section. The third section examines the changing context of governance and the capacity of the state to act to steer the transition. This allows us to identify, in our final concluding section, a set of critical topics for those researching and implementing the smart mobility revolution.
