Heterogeneous risk tolerance, in-groups, and epidemic waves.

There is a growing interest in the joint modeling of the dynamics of disease and health-related beliefs and attitudes, but coupling mechanisms are yet to be understood. We introduce a model where risk information, which can be delayed, comes in two flavors, including historical risk derived from perceived incidence data and predicted risk information. Our model also includes an interpretation domain where the behavioral response to risk information is subject to in-group pressure.

Meddling in the 2016 Elections and Satisfaction With Democracy in the US.

In this article, we investigate how external election interventions influence satisfaction with democracy. We expect that mere knowledge about a foreign intervention will affect system support. Instead, only those who believe that the external influence campaign had a decisive impact on the election outcome should see a reduction in democratic satisfaction.

The logical structure of experiments lays the foundation for a theory of reproducibility.

The scientific reform movement has proposed openness as a potential remedy to the putative reproducibility or replication crisis. However, the conceptual relationship among openness, replication experiments and results reproducibility has been obscure. We analyse the logical structure of experiments, define the mathematical notion of idealized experiment and use this notion to advance a theory of reproducibility.

The preference for belief, issue polarization, and echo chambers.

Some common explanations of issue polarization and echo chambers rely on social or cognitive mechanisms of exclusion. Accordingly, suggested interventions like "be more open-minded" target these mechanisms: avoid epistemic bubbles and don't discount contrary information. Contrary to such explanations, we show how a much weaker mechanism-the preference for belief-can produce issue polarization in epistemic communities with little to no mechanisms of exclusion.

High variability in anterior cruciate ligament femoral footprint: Implications for anatomical anterior cruciate ligament reconstruction.

Background: The study aimed to (1) investigate the variability of the femoral ACL center in ACL-ruptured patients, (2) identify whether the currently available over-the-top femoral ACL guides could allow for anatomical reconstruction of the native ACL footprint.

Material And Methods: Magnetic resonance images of 95 knees with an ACL rupture were used to create three-dimensional models of the femur. The femoral ACL footprint area was outlined on each model, and the location of the femoral ACL center was reported using an anatomical coordinate system.
