The personalization of politics, whereby politicians increasingly become the main focus of political processes, is a prominent phenomenon in modern democracies that has received considerable scholarly attention in national politics. However, little is known about the scope, causes and consequences of personalization in European Union politics, although recent institutional and political developments suggest that such a trend is underway. This book sheds light onto this phenomenon by taking a comprehensive approach to understanding four key dimensions of personalization concerning institutions, media, politics, and citizens. In doing so, it relies on an innovative longitudinal and cross-count...
The book demonstrates an evidence-based approach to online memory practices of World War II. Network analysis is applied to reduce a massive and unreadable dataset of forum texts and user relations. Further, the results are combined with other text analysis methods, such as topic modeling and contrastive stylometric analyses. A sample of discussions from each group is read and categorized. Based on the results, the forum users‘ memory practices are labelled as empirical, conversational and conservational practices, whereby recent theoretical developments in Memory Studies are considered.

This book provides a concise and engaging analysis of the particularly unusual 2020 election year in the USA. The political science perspective illuminates societal tensions in the context of the Corona pandemic and elaborates election-deciding discourses. Larger socio-political trends such as ideological polarisation are addressed as well as the different campaign strategies of the two parties. In addition, the book offers insights into the election results of this landmark presidential election for American society and for the development of its democracy. The final evaluation of the resulting implications for transatlantic relations rounds off the book.
This book looks at how the language of the law has changed over time, and how this has empowered judges. In particular it looks at how this has empowered judges to rule against governments.
Key party goals serve to advance a policy brand and maximize seats in the legislature. This book offers a theory of how political parties assign their elected members -- their "personnel" -- to specialized legislative committees to serve collective organizational goals, here known as "party personnel strategies". Individual party members vary in their personal attributes, such as prior occupation, gender, and local experience. Parties seek to harness the attributes of their members by assigning them to committees where their expertise is relevant, and where they may enhance the party's policy brand. However, under some electoral systems, parties may need to trade-off the harnessing of expert...
This book analyzes the threshold candidates of immigrant background need to overcome to run for legislative office. Understanding whether political parties are able to adapt their selection criteria helps to assess their ability to respond to the underrepresentation of citizens of immigrant origin in parliament. Although Germany’s ethnic diversity is on a steady rise, citizens of immigrant origin remain descriptively underrepresented. Despite the pivotal role the intra-party candidate selection plays in shaping who runs for election, the question of how candidates of immigrant background fare in political parties’ candidate selection in comparison to native-born candidates remained a blind spot of research. Therefore, the author presents in-depth empirical evidence on the selection of candidates of immigrant background in German political parties. The book addresses scholars of political science interested in electoral studies as well as policy-makers and party officials interested in a balanced representation of their political representatives.
