What Does It Take for Immigrants to Join Political Parties?

Political parties are crucial agents in democratic representation and political integration of persons of immigrant origin, a growing category of citizens in the European Union. Research demonstrates that citizens of immigrant origin are less likely to join political parties than persons without a migratory background. Nevertheless, party membership varies across countries and between immigrants. Accounting for such inter-individual and cross-national variations, this article uses secondary data from the European Social Survey, the Migrant Integration Policy Index, and the Varieties of Democracy (V-Dem) project for 25 European democracies to uncover mechanisms that explain the party membership of immigrants. In our multilevel analysis, we test interactions between country-specific variations in legislation on migration policies on the one hand and individual differences in political socialisation and political efficacy on the other. Our models suggest significant positive effects of exposure to a democratic regime in the country of origin and of internal efficacy on party membership of citizens of immigrant origin. Additionally, our findings highlight the significance of an inclusive national framework for immigrant integration, serving as a moderator to diminish the impact of political socialisation in less democratic countries on the decision of citizens with immigrant backgrounds to participate in political parties within their country of residence

Roll-Call Votes in the German Bundestag: A New Dataset, 1949-2013

This letter introduces a comprehensive data collection on roll-call votes (RCVs) in the German Bundestag between 1949 and 2013. RCVs are one of the most important data sources on parliamentary behavior. Beyond producing legislative output, RCVs put the positions of Members of Parliament (MPs) and party groups on the public record, serve party leaders as an instrument with which to monitor backbench behavior, and enable opposition parties to obstruct parliamentary business (Saalfeld 1995a). RCVs from various parliaments have been used to investigate, among others, party competition and legislative coalition formation, the strategic behavior of individual MPs and legislative parties, party unity and intraparty politics, and MP responsiveness to voters and other outside interests (for example, Carey 2007; Carrubba, Gabel and Hug 2008; Eggers and Spirling 2016; Hix 2004; Hix and Noury 2016; Poole and Rosenthal 1997). Empirical research can rely on comprehensive longitudinal roll-call data for a number of countries, most notably the US Congress (for example, Lewis et al. 2017; Poole and Rosenthal 1997),1 the European Parliament (Hix, Noury and Roland 2005), and the British House of Commons (for example, Eggers and Spirling 2016; Norton 1975); on some cross-country comparative datasets for shorter periods of time (Carey 2007; Coman 2015; Hix and Noury 2016; Sieberer 2006); and on numerous contemporary and historical single-country datasets.2 For the German Bundestag, RCV data has thus far only been available for limited periods of time (Ohmura 2014b; Saalfeld 1995b; Sieberer 2010; Stratmann 2006). At the same time, the Bundestag is an attractive parliament to study. It is one of the most powerful legislatures in a parliamentary democracy (Sieberer 2011); its internal organization is rather elaborate (Saalfeld 2000); and its mixed electoral system offers attractive opportunities to analyze one of the most fundamental aspects of legislative behavior: the effect of electoral rules on legislative voting (for example, Manow 2015; Sieberer 2010; Sieberer 2015). The datasets described here contain information on individual voting behavior and a wide array of variables that characterize the MPs and RCVs they voted on. The data are freely available to the academic community at Harvard Dataverse.3 In this letter, we describe the structure of the datasets, present descriptive information on key variables and discuss potential research questions to be addressed with the data

The behaviour of political parties and MPs in the parliaments of the Weimar Republic

Copyright @ 2012 The Authors. This is the author's accepted manuscript. The final published article is available from the link below.Analysing the roll-call votes of the MPs of the Weimar Republic we find: (1) that party competition in the Weimar parliaments can be structured along two dimensions: an economic left–right and a pro-/anti-democratic. Remarkably, this is stable throughout the entire lifespan of the Republic and not just in the later years and despite the varying content of votes across the lifespan of the Republic, and (2) that nearly all parties were troubled by intra-party divisions, though, in particular, the national socialists and communists became homogeneous in the final years of the Republic.Zukunftskolleg, University of Konstan

Polarized light-flavor antiquarks from Drell-Yan processes of h+\vec{N}\to\vec{l^{+-}} + l^{-+} + X

We propose a formula to determine the first moment of difference between the polarized $\bar u$- and $\bar d$-quarks in the nucleon, {\it i.e.} $\Delta\bar u-\Delta \bar d$ from the Drell-Yan processes in collisions of unpolarized hadrons with longitudinally polarized nucleons by measuring outgoing lepton helicities. As coefficients in the differential cross section depend on the $u$- and $d$-quark numbers in the unpolarized hadron beam, the difference $\Delta\bar u-\Delta\bar d$ can be independently tested by changing the hadron beam. Moreover, a formula for estimating the $K$-factor in Drell-Yan processes is also suggested.Comment: 10 pages, 1 figur

Election proximity and representation focus in party-constrained environments

Do elected representatives have a time-constant representation focus or do they adapt their focus depending on election proximity? In this article, we examine these overlooked theoretical and empirical puzzles by looking at how reelection-seeking actors adapt their legislative behavior according to the electoral cycle. In parliamentary democracies, representatives need to serve two competing principals: their party and their district. Our analysis hinges on how representatives make a strategic use of parliamentary written questions in a highly party-constrained institutional context to heighten their reselection and reelection prospects. Using an original data set of over 32,000 parliamentary questions tabled by Portuguese representatives from 2005 to 2015, we examine how time interacts with two key explanatory elements: electoral vulnerability and party size. Results show that representation focus is not static over time and, in addition, that electoral vulnerability and party size shape strategic use of parliamentary questions

MPs’ principals and the substantive representation of disadvantaged immigrant groups

This article provides an alternative understanding of the substantive representation of immigrant-origin citizens compared to previous work in the ‘politics of presence’ tradition. Rather than assuming that the representational activities of members of parliaments (MPs) are underpinned by intrinsic motivations, it highlights extrinsic motives. Drawing on principal–agent theory, the article conceptualises MPs as delegates who are to act on behalf of their main principals, constituents and party bodies. This approach permits the rigorous analysis of the impact of electoral rules, candidate selection methods and legislative organisation on substantive representation. Based on an analysis of more than 20,000 written parliamentary questions tabled in the 17th German Bundestag (2009–2013), empirical findings suggest that electoral rules do not influence the relationship between MPs and their principals in relation to the substantive representation of disadvantaged immigrant groups; however, results indicate that candidate selection methods as well as powerful parliamentary party group leaderships do

Polygamy slows down population divergence in shorebirds.

Sexual selection may act as a promotor of speciation since divergent mate choice and competition for mates can rapidly lead to reproductive isolation. Alternatively, sexual selection may also retard speciation since polygamous individuals can access additional mates by increased breeding dispersal. High breeding dispersal should hence increase gene flow and reduce diversification in polygamous species. Here we test how polygamy predicts diversification in shorebirds using genetic differentiation and subspecies richness as proxies for population divergence. Examining microsatellite data from 79 populations in ten plover species (Genus: Charadrius) we found that polygamous species display significantly less genetic structure and weaker isolation-by-distance effects than monogamous species. Consistent with this result, a comparative analysis including 136 shorebird species showed significantly fewer subspecies for polygamous than for monogamous species. By contrast, migratory behaviour neither predicted genetic differentiation nor subspecies richness. Taken together, our results suggest that dispersal associated with polygamy may facilitate gene flow and limit population divergence. Therefore, intense sexual selection, as occurs in polygamous species, may act as a brake rather than an engine of speciation in shorebirds. We discuss alternative explanations for these results and call for further studies to understand the relationships between sexual selection, dispersal and diversification.
