Lehrkräfteverbände wurden bislang in Untersuchungen zur Schulpolitik als Akteure vernachlässigt. Der Vergleich der Schulpolitiken in Frankreich und Deutschland auf dem Feld output- und wettbewerbsorientierter Reformen zeigt, dass Verbände von Lehrkräften in der Politikgestaltung eine wichtige Rolle spielen. In Frankreich konnten Lehrkräfteverbände Vorhaben zur Stärkung interner und externer Evaluationen sowie Wettbewerbsmaßnahmen blockieren. In Deutschland blieb der Widerstand von Verbänden dagegen aus und der Fokus richtete sich eher auf Feinjustierungen der Maßnahmen. Der Beitrag untersucht, inwieweit die unterschiedlichen Umsetzungen auf Machtpositionen sowie Interessen und Strategien der Verbände von Lehrkräften zurückgeführt werden können.

This research note presents EPAC 2017, a dataset resulting from the second round of an expert survey on ethnonationalism in party competition. EPAC provides cross-sectional data on the positions of (ethno-) national and mainstream parties on an ethnonational (also often referred to as ‘territorial’ or ‘centre-periphery’) dimension, as well as other important dimensions of political competition. The 2017 edition covers 222 political parties in 22 multinational European countries. The research note presents the main survey items and performs a series of validity and reliability tests on the data. Results show that EPAC 2017 provides valid and reliable measures of party positions on an ethnonational dimension. A short analysis of party system changes in Spain and Bosnia and Herzegovina illustrates the opportunities of combining the 2011 and 2017 editions. The combined dataset allows studying the mobilization of the centre-periphery cleavage in party competition across Eastern and Western Europe and over time.

The paper examines the role of education as a causal channel through which growing up poor affects the economic outcomes in adulthood in the European Union. We apply a potential outcomes approach to quantify those effects and we provide a sensitivity analysis on possible unobserved confounders, such as child ability. Our estimates indicate that being poor in childhood significantly decreases the level of income in adulthood and increases the average probability of being poor. Moreover, our results reveal a significant role of education in this intergenerational transmission. These results are particularly relevant for Mediterranean and central and eastern European countries.

This paper presents empirical evidence on a recent advancement of the item count technique (ICT, a survey technique for asking sensitive questions), namely, the person count technique (PCT; Grant, Moon, & Gleason, 2014). PCT utilizes person lists instead of lists of filler questions, as is the case in the classic ICT design. This simplifies the questioning procedure, but leads to some methodological challenges such as floor and ceiling effects. The main part of this paper presents empirical evidence stemming from an experimental postal survey in Germany (N = 580) investigating how well PCT performs as compared to standard direct questioning (DQ) with regard to alleviating misreporting for questions on attitudes towards refugees. PCT prevalence estimates for hostile attitudes towards refugees are significantly higher than DQ estimates for one item, and non-significantly higher for three items. Although not consistently significant, the differences are substantial, amounting to a threefold increase of the proportion of respondents expressing negative attitudes towards refugees. Even though the findings are not unequivocally in favor of PCT, this new ICT variant still deserves consideration in the future and warrants further development. Specifically, more knowledge is required with respect to its statistical properties and the best practices of its implementation.

The Crosswise Model (CM) has been proposed as a method to reduce effects of social desirability in sensitive questions. In contrast with former variants of Randomized Response Techniques (RRTs), the crosswise model neither offers a self-protective response strategy, nor does it require a random device. For these reasons, the crosswise model has received a lot of positive attention in the scientific community. However, previous validation studies have mostly analysed negatively connoted behaviour and thus draw on the principle of “more is better”. Higher prevalence rates of socially undesirable behaviour in the crosswise model cannot be attributed unambiguously to a reduction in social desirability bias, since random ticking resulting from respondent confusion about the question format cannot be ruled out as an alternative explanation. Unlike most research on crosswise models and randomized response techniques, we conduct an experiment in a general population survey that does not assess negatively connoted but socially desirable behaviour (namely, whether respondents had donated blood within the last twelve months). This design allows us to empirically disentangle the reduction of social desirability bias from random responses. We find signifcantly higher prevalence rates in the crosswise condition than in the direct question. What is more, we could not identify any subgroup of respondents, in which the CM successfully reduced social desirability bias. These results cast doubts on the validity of cosswise models. They suggest that a considerable number of respondents do not comply with the intended procedure.
