LLM-Mediated Findability of Research Datasets

This study evaluates the LLM-mediated findability of research datasets. The sample uses 100 datasets randomly selected from GESIS. Experiments were run using web-search-based models from OpenAI and Gemini. Six different query strategies combine metadata such as topic, geography,...

Prediction-Based Adaptive Designs for Reducing Wave Nonresponse Rates and Bias in Panel Surveys

Machine learning (ML)-based nonresponse prediction in panel surveys enables selective interventions. However, the optimal use of ML predictions in Adaptive Survey Design (ASD) remains uncertain. We propose a method that integrates field experiment results on incentives, questionn...

How sociodemographic factors shape the link between personality and cognitive ability

This study systematically investigated how links between personality traits and cognitive ability vary across key sociodemographic strata. Numerous studies have supported a robust but modest association between cognitive ability and certain personality traits, notably Big Five Op...

The impact of dimensionality on the stability of node embeddings

Abstract Previous work has shown that node embedding methods can produce different representations and downstream predictions across repeated training runs, even when trained on the same data with identical hyperparameters. However, the role of embedding dimensionality in this in...

Do emotions affect political trust judgments?

Abstract Our study explores the nature of political trust ratings in surveys. We provide novel empirical evidence that, in addition to informed and rational reasoning, emotional states play a role in trust evaluations. Leveraging a U.S. sample, we employ a novel smartphone survey...

Vaccine hesitancy beyond borders: a multi-sited study of migrants and non-migrants across Germany and Turkey

Vaccination is a key protective measure against infectious diseases, yet vaccine hesitancy is rising, and coverage remains lower among migrant populations. Research largely attributes gaps to migrants’ characteristics, such as higher religiosity, overlooking broader mechanisms. W...

Being journalists on social media: Contrasting professionals’ self-perceptions to role expectations among adolescents

On social media, efforts by individual journalists to share news with audiences may be a viable response to personality-driven news presentation coming from peripheral actors like influencers, who are increasingly popular information sources for adolescents. Yet, when using socia...

Bi-national academic funding and collaboration dynamics: the case of the German-Israeli foundation

Abstract Academic grant programs are widely used to motivate international research collaboration and boost scientific impact across borders. Among these, bi-national funding schemes–pairing researchers from just two designated countries–are common yet understudied compared with...
