Learning from agrarian dynamics to tailor community-led forest restoration in the Tshopo province, Democratic Republic of the Congo
The strategies and efficacy of forest restoration initiatives in Central Africa are poorly documented. To this end, we examined the usefulness of a holistic methodology (combining agricultural diagnosis with forestry measurement) to explain the results of a forest restoration project in Tshopo Province in the DRC. To do this, an initial analysis based on the agrarian diagnostic structure was carried out and linked to project monitoring data ‐ int…
Speaking their language: Multilingualism in party communication across democracies
Which parties embrace multilingualism in their communication? Despite growing interest in parties’ multilingualism among normative scholars of deliberative democracy, empirical research has largely overlooked the linguistic aspect of party competition. We leverage large‐scale data on Facebook posts by more than 800 parties in 87 democracies and analyze their day‐to‐day language practices. By so doing, we develop, for the first time, the classific…
Political Deepfakes Are as Credible as Other Fake Media and (Sometimes) Real Media

Polarization but not populism strengthens the association between presidential election results and emotions
We investigate whether election results are associated with emotional reactions among voters across democracies and under what conditions these responses are more intense. Building on recent work in comparative politics, we theorize that emotional intensity is stronger after elections involving populist candidates and highly polarized parties. We test these expectations with a big-data analysis of emotional reactions on parties’ Facebook posts du…
Testing Causal Theories with Learned Proxies
Social scientists commonly use computational models to estimate proxies of unobserved concepts, then incorporate these proxies into subsequent tests of their theories. The consequences of this practice, which occurs in over two-thirds of recent computational work in political science, are underappreciated. Imperfect proxies can reflect noise and contamination from other concepts, producing biased point estimates and standard errors. We demonstrat…
A Dynamic Model of Speech for the Social Sciences
Speech and dialogue are the heart of politics: nearly every political institution in the world involves verbal communication. Yet vast literatures on political communication focus almost exclusively on what words were spoken, entirely ignoring how they were delivered-auditory cues that convey emotion, signal positions, and establish reputation. We develop a model that opens this information to principled statistical inquiry: the model of audio an…
Universality and diversity in human song
Cross-cultural analysis of song It is unclear whether there are universal patterns to music across cultures. Mehr et al. examined ethnographic data and observed music in every society sampled (see the Perspective by Fitch and Popescu). For songs specifically, three dimensions characterize more than 25% of the performances studied: formality of the performance, arousal level, and religiosity. There is more variation in musical behavior within soci…
Investigator Characteristics and Respondent Behavior in Online Surveys
Prior research demonstrates that responses to surveys can vary depending on the race, gender, or ethnicity of the investigator asking the question. We build upon this research by empirically testing how information about researcher identity in online surveys affects subject responses. We do so by conducting an experiment on Amazon’s Mechanical Turk in which we vary the name of the researcher in the advertisement for the experiment and on the info…
Digital literacy, fake news and education
The role of digital literacy in strengthening citizens’ resilience to misinformation and ‘fake news’ has been the subject of research projects and networking and academic and policy discourses in recent years, given prominence by an escalation of the perceived crisis following election and referendum results in the US and UK respectively. This special issue sets out to take forward critical dialogue in the field of media and digital literacy educ…
Computer-Assisted Text Analysis for Comparative Politics
Recent advances in research tools for the systematic analysis of textual data are enabling exciting new research throughout the social sciences. For comparative politics, scholars who are often interested in non-English and possibly multilingual textual datasets, these advances may be difficult to access. This article discusses practical issues that arise in the processing, management, translation, and analysis of textual data with a particular f…
The Ties That Bind: National Identity Salience and Pro-Social Behavior Toward the Ethnic Other
At the psychological level, ethnic conflict can be seen as an extreme result of normal group identification processes. Bridging perceived intergroup boundaries is therefore key to improving intergroup relations. In contrast to the dominant association of nationalism with racism, chauvinism, xenophobia, and intolerance, we highlight the constructive potential of national identification. In a survey experiment, we find that the increased salience o…
Structural Topic Models for Open‐Ended Survey Responses
Collection and especially analysis of open‐ended survey responses are relatively rare in the discipline and when conducted are almost exclusively done through human coding. We present an alternative, semiautomated approach, the structural topic model (STM) (Roberts, Stewart, and Airoldi 2013; Roberts et al. 2013), that draws on recent developments in machine learning based analysis of textual data. A crucial contribution of the method is that it …
Contact as catalyst: The case for Coptic influence in the development of Arabic negation
This article discusses similar developments in the expression of negation in the histories of Egyptian-Coptic and Arabic and explores the evidence for these respective developments being related by language contact. Both Coptic and Arabic have undergone a development known as Jespersen's Cycle (JC), whereby an original negative marker is joined by some new element to form a bipartite negative construction. The original marker then becomes optiona…
