To vaccinate or not to vaccinate? The role of personality.

This article presents findings on the personality traits of individuals who identified as either Vaxxers (V) or Anti-Vaxxers (AV) during the COVID-19 pandemic. The study administered measures of Dark Triad traits (Machiavellianism, Narcissism, and Psychopathy), trait emotional intelligence, and personality to a sample of 479 participants (283 Vs and 196 AVs) recruited via mTurk. Results indicated that Vaxxers scored higher on HEXACO Honesty and Conscientiousness while Anti-Vaxxers scored higher on the Dark Triad and trait emotional intelligence.

Engagement With and Acceptability of Digital Media Platforms for Use in Improving Health Behaviors Among Vulnerable Families: Systematic Review.

Background: The use of digital communication platforms to improve health behaviors has increased dramatically over the last decade. Public health practitioners have adopted digital communication technologies such as text messages, mobile apps, and social media to reach diverse populations. However, the effectiveness of digital communication platforms used by community-serving agencies remains unclear, and patterns of engagement and acceptability of different platforms have not been studied.

Political Hearts of Darkness: The Dark Triad as Predictors of Political Orientations and Interest in Politics.

Background: This study investigated the relationships between the Dark Triad of personality (sub-clinical psychopathy, Machiavellianism, and narcissism) and four political variables: socio-religious conservatism, support for greater economic equality, overall liberal-conservative orientation, and interest in politics. A theoretical approach that focused on the influence of the Dark Triad in large groups was provided to interpret those relationships. Methodological issues found in previous research that related to the use of abbreviated scales to measure the dark traits and the use of unidimensional indicators of political orientations were addressed.

Fifty million years of beetle evolution along the Antarctic Polar Front.

Global cooling and glacial-interglacial cycles since Antarctica's isolation have been responsible for the diversification of the region's marine fauna. By contrast, these same Earth system processes are thought to have played little role terrestrially, other than driving widespread extinctions. Here, we show that on islands along the Antarctic Polar Front, paleoclimatic processes have been key to diversification of one of the world's most geographically isolated and unique groups of herbivorous beetles-Ectemnorhinini weevils.

Spotlight on the invasion of a carabid beetle on an oceanic island over a 105-year period.

The flightless beetle Merizodus soledadinus, native to the Falkland Islands and southern South America, was introduced to the sub-Antarctic Kerguelen Islands in the early Twentieth Century. Using available literature data, in addition to collecting more than 2000 new survey (presence/absence) records of M. soledadinus over the 1991-2018 period, we confirmed the best estimate of the introduction date of M.
