This summary of the project’s technical and scientific achievements as of June 2025 (the first two years of the project) follows the order of the project’s work packages, and all publications noted here are available on the project website’s “publications” page:
https://www.prd-erc.eu/publications(opens in new window) “Political acts and political participators” (WP1) analyzes separate surveys and a harmonized dataset, and includes methodological innovations using new latent variable techniques for identifying participation repertoires. Main achievements include: completed findings report drafts for the main survey programs; construction of original harmonized dataset repository; and the creation of an open-source software package in R to conduct multilevel latent class analysis (multilevLCA).
Key publications relevant for this work package include:
-Han, Baggetta & Oser (2024) “Organizing and Democracy” in the American Review of Political Science
-Lyrvall, Di Mari, Bakk, Oser & Kuha (2025, in press) “Multilevel Latent Class Analysis: State-of-the-art Methodologies and Their Implementation in the R Package multilevLCA” in Multivariate Behavioral Research
-An accepted journal symposium on data harmonization in PS: Political Science & Politics, coedited by Kołczyńska, Kritzinger & Oser
“Participation-representation connection” (WP2) investigates the connections between political participation analyzed in WP1 and representational outcomes. Even though the majority of the research plan for WP2 was intended to take place in years 3-5, we have already advanced two manuscripts under review (one of which has already received an R&R from a top journal), and three conference papers that are in preparation for journal submission. In addition, we added a new line of research to this work package on literature mapping in the social sciences, which has already produced the following article:
-Shoshan & Oser (2025) “Visualizing Scientific Landscapes”
“Mobilizing and organizing low-status groups” (WP3) analyzes social media data and conducts experimental research to identify interventions with the potential to produce more equal representational outcomes in the future. We have completed the planned observational analysis of the Twitter panel that identifies distinct types of curators of political information for sociodemographic groups. Relevant publication:
-Shamir, Oser & Grinberg (2024), “Who is Curating My Political Feed?”
