RESUMO
Scientists increasingly use Twitter for communication about science. The microblogging service has been heralded for its potential to foster public engagement with science; thus, measuring how engaging, that is dialogue-oriented, tweet content is, has become a relevant research object. Tweet content designed in an engaging, dialogue-oriented way is also supposed to link to user interaction (e.g. liking, retweeting). The present study analyzed content-related and functional indicators of engagement in scientists' tweet content, applying content analysis to original tweets (n = 2884) of 212 communication scholars. Findings show that communication scholars tweet mostly about scientific topics, with, however, low levels of engagement. User interaction, nevertheless, correlated with content-related and functional indicators of engagement. The findings are discussed in light of their implications for public engagement with science.

In order to explain the behavior of political elites, research increasingly considers personality traits. Within this line of research, a recent focus is on socially aversive - yet non-pathological - personality traits (e.g., Machiavellianism, narcissism, psychopathy), with the idea to better understand behavior violating generally accepted ethical, moral, and social norms. Assessments of politicians' aversive personality traits have so far been almost exclusively based on observer reports of experts and voters. Herein, by contrast, we introduce the Political Elites Aversive Personality Scale ("PEAPS") particularly tailored to measure self-reported aversive personality among politicians. More precisely, based on two studies with German politicians, we develop a 6-item short scale comprising aspects of different socially aversive personality traits (Machiavellianism, narcissism, psychopathy, and spitefulness). The scale shows an acceptable model fit, an acceptable internal consistency, an acceptable measurement equivalence, and meaningful correlations with other (self-reported) psychological traits and campaign behavior. Moreover, the scale significantly contributes to the explanation of candidates' negative campaigning, going beyond the explanatory power of models capturing broad, basic personality traits. Overall, the suggested scale provides interesting links to research in (political) psychology and can help to explain attitudes, behavior, and performance of political elites.
