"Pooling time series based on slightly different questions about life satisfaction. Application of the reference distribution method to time series on life satisfaction". Presented by Dr. Tineke de Jonge (Senior Volunteer of the World Database of Happiness at the Erasmus University Rotterdamn). (December 21, 2016)

Abstract: Subjective well-being has traditionally been measured using verbal response scales, yet, these verbal scales have not kept up with the present trend to use numerical response scales. A switch from a verbal scale to a numerical scale, however, causes a severe problem for trend analyses, due to the incomparability of the old and new measurements. The Reference Distribution Method has been developed recently to deal with this comparison problem. The idea that underlies this method is that the estimated means for equivalent questions about the same topic asked in different representative surveys in one year should be approximately the same when compared irrespective of the primary response scales used. In the Reference Distribution Method use is made of a reference distribution based on the responses to a numerical 10- or 11-point scale which is used to decide at which points response options from a verbal scale transit from one state to an adjacent state, for example from ‘fairly satisfied’ to ‘very satisfied’. Next, for each wave of the time series in which the verbal scale is used, a population mean is estimated using all these transition points and the responses in this wave. These estimates are on a level that is comparable to that of the mean of the reference distribution and are appropriate for use in an extended time series based on the response frequencies measured using a verbal and a numerical scale. We applied the Reference Distribution Method to pool time series on life satisfaction in the USA, Japan, The Netherlands and Spain, using results from the World Values Survey to derive reference distributions from. This resulted in consistent time series spanning a time period of almost 60 years for Japan, 40 years for The Netherlands and 35 years for the USA and Spain. Life satisfaction in Japan and The Netherlands was almost equal in the eighties, but at present differs more than one point in favor of The Netherlands. Life satisfaction in Spain reached the lowest value of 6.0 in 2012, but has increased since then to 6.3 in 2015.


"Why should we and how could we study migrants". Dr. Ineke Stoop (Senior methodologist at The Netherlands Institute for Social Research/SCP and Deputy Director Methodological of the European Social Survey). (December 21, 2016)

Abstract: To be able to fully understand migration, information from migrants is required. This information should cover their socio-demographic and socio-economic characteristics and cultural backgrounds, but also their reasons for migration, their aspirations and preferences, and their experiences in the country they migrate to. This information can partly be drawn from registers, but in many cases surveys (and sometimes qualitative studies) will be required to fully grasp why people migrate, how they are treated, what they expect and whether these expectations have been met. Studying migration is far from easy. Firstly, the target population may be hard to define in advance. When are temporary labour migrants migrants? Secondly, not all migrants are registered in the country where they move to, for several reasons. In addition, migrants living in hostels and other non-residential living conditions are often excluded from general social surveys. Thirdly, migrants may be harder to contact, may refuse to participate in a survey, and may not be able to participate for specific reasons, including language problems. Deploying native speaking interviewers and translated questionnaire may solve some of these problems, but will almost inevitably result in measurement problems and may possibly hamper comparability across groups. The presentation will outline the differing aims when surveying migrants, efforts that can be made to increase representativeness, and the challenges of cross-national and cross-group comparability. Guidelines for comparative survey design and implementation will be presented, and examples from Dutch surveys among migrants.


"The Roles of Media Choice and Media Effects in Political Knowledge Gaps". Presented by Dr. Thomas J. Leeper (Assistant professor in Political Behaviour in the Depatment of Goverment at the London School of Economics). (July 5, 2016)

Abstract: Mass media are frequently cited as having the potential to reduce political knowledge gaps between citizens, but are also seen as a force for segmentation, disengagement, and widening gaps. If media have no effect on political knowledge, gaps between the engaged and disengaged persist regardless of who is exposed to news. But gaps can also persist if those who are inclined to seek out news learn just as much or as little as those who are disinclined to attend to the news but happen across it incidentally because uniform gains in knowledge do not reduce knowledge inequalities. Indeed, gaps can only be closed by media if the effects of news exposure are larger for those who tend to avoid media exposure than for those who are inclined to attend to the news. Yet past research on political communication has not sufficiently acknowledged the connection between knowledge gaps, media choice, and the heterogeneity of media effects. The present study contributes a novel and large-scale choice-based experiment on knowledge of the ongoing crisis in Syria that finds media effects are relatively homogeneous across those with different media preferences, suggesting that under most conditions knowledge gaps between the politically engaged and disengaged are widened or at least sustained even when everyone learns from the news. Under no realistic conditions are gaps between these groups overcome by media use.


"Can Citizens Think Coherently about Politics? The Problems of Preference Reversal and Political Ideology". Presented by Dr. Paul M. Sniderman (Fairleigh S. Dickinson, Jr. Professor in Public Policy). (3 May, 2016)

Abstract: It is the judgment of some of the most distinguished public opinion researchers that citizens are not capable of forming genuine preferences about major political issues.  It is the consensus of most public opinion specialists that ordinary citizens are not capable of organizing their political ideas along ideological lines. The obstacle is the minimal amount of attention that most citizens pay to politics and therefore the minimal amount of information that most have about it.  I shall show that changes in political preferences that have appeared to be changes for no good reason often are changes for good reason and  propose a solution to the inadequate information problem.

"Cross-National Surveys: the example of the European Social Survey". Presented by Ineke Stoop (Senior methodologist at The Netherlands Institute for Social Research/SCP Deputy Director Methodological of the European Social Survey). (October 7, 2015)

Abstract: Cross-national surveys play an important role in our societies. They are at the base of comparative social research and provide information on key issues in our societies. To fulfil this role they must pursue two potentially conflicting aims: high quality and optimal comparability across countries and over time. The presentation will focus on the European Social Survey, an academically driven face-to-face survey, started in 2002 and conducted biennially in more than 30 European countries. It presents the aims of the ESS, the history and the organisation, and then focuses on the content and the methodology. The main theme will be the pursuit of quality and comparability, given time, budgetary and practical constraints. The presentation will also comprise a short overview of other cross-national surveys.


"Multilevel Models for Comparative Longitudinal Survey Data: Techniques, Problems, and Advice". Presented by Dr. Malcolm Fairbrother (Senior Lecturer in Global Policy and Politics University of Bristol). (May 5, 2015)

Abstract: Many surveys of respondents from multiple countries or sub-national regions have now been fielded on multiple occasions. This presentation will first describe two useful techniques for analysing such datasets, using multilevel models. These techniques treat y as a function of some time-varying x and/or of a time-invariant x, thereby illuminating the correlates of social or political change. The presentation will then address some potential problems in multilevel models fitted to comparative longitudinal survey data, showing that in published research such models have often been specified erroneously. They have often omitted one or more relevant random effects, thereby ignoring important clustering in the data, leading to downward (anticonservative) biases in the standard errors. Monte Carlo simulations and empirical examples illustrate both the techniques and the problems, and point to some simple recommendations for making reliable inferences from multilevel models.


"Demography, Destiny, and American Politics:  How Latinos, Immigration, and the Changing Face of America Will Define the Next US Election". Presented by Dr. Gary Segura (Professor​, Department of Political Science​, Stanford University and​ Principal and Co-Founder ​Latino Decisions). (April 21, 2015)

Abstract: The future shape of American politics will be determined, in large measure, by how Latinos are incorporated into the political system.  The combination of population growth and growth in the electorate, combined with Latino electoral history as a population with significant inter-election movement over time, suggests that both political parties face opportunity in their approach to current and future generations of Latino voters. Latino population growth is coupled with a broader-scale diversification of the US on racial and ethnic lines.  It is true that Latinos are a complex group and that complexity makes for a politics more nuanced and less lock-step than the media and casual observers might conclude.  Nevertheless, over the last several elections, there can be little question that Latinos have become a political force-perhaps still weaker than their potential but a force nonetheless.  It is in this context that the current policy debate over immigration and immigrants--current and yet ongoing for most of the last 20 years--has become the critical litmus test by which Latinos evaluate candidates as "friendly," a test that (with few exceptions) the Republican Party and its candidates have repeatedly failed.  In this presentation, I will illustrate the demographic and issue bases of Latino political power and what they might portend for the next period of American elections.​
