Gender Differences in Risk Markers for Perpetration of Physical Partner Violence: Results from a Meta-Analytic Review

There is a lack of consensus on whether the use of intimate partner violence (IPV) is distinctly different between men and women, or if men and women share similar risk markers for perpetrating IPV. In this study, we compared 60 different risk markers for IPV perpetration for men and women using a meta-analysis. We found three out of 60 risk markers significantly differed between men and women. Our results suggest that there are more similarities between men and women than there are differences in risk markers for IPV perpetration.     

Dynamics of Polarizing Rhetoric in Congressional Tweets

Affective polarization is pervasive in modern US politics, and can be intensified by strategic messaging from members of Congress. But there are gaps in our knowledge of the dynamics of polarizing appeals from elected representatives on social media. We explore the usage of polarizing rhetoric by members of Congress on Twitter using the 4.9 million tweets sent by members of Congress from 2009 to 2020, coded for the presence of polarizing rhetoric via a novel and highly accurate application of supervised machine learning methods. Fitting with our expectations, we find that more ideologically extreme members, those from safer districts, and those who are not in the president’s party are more likely to send polarizing tweets, and that polarizing tweets garner more engagement, increasing campaign funding for more polarizing members.
