Self-monitoring and former best friends: individual differences in friendship dissolution.

Across two investigations, we explored self-monitoring differences in the causes of relationship dissolution with best friends and if such differences are best captured by a univariate model or bivariate model of self-monitoring. Causes of friendship dissolution often mirror the reasons for friendship formation. Accordingly, we hypothesized that high self-monitors would report a change in shared activities as the reason for dissolving a relationship with a best friend, whereas low self-monitors would report a change in personal compatibility as the reason for dissolving a relationship with a best friend.

Conflict Moderates the Longitudinal Association between Aggression with Classmates and Popularity: Leveraging Disagreements into Peer Status.

The present study tests the hypothesis that conflict amplifies longitudinal associations from aggressiveness and disruptiveness to classroom popularity. Participants were 356 (181 girls, 172 boys) Florida primary school students (ages 8-12). The results revealed that higher initial levels of peer-reported aggression, and disruptiveness were associated with increases in peer-reported popularity, particularly for children who report frequent conflict with classmates.

Role of the Metal-Semiconductor Interface in Halide Perovskite Devices for Radiation Photon Counting.

Halide perovskites are promising optoelectronic semiconductors. For applications in solid-state detectors that operate in low photon flux counting mode, blocking interfaces are essential to minimize the dark current noise. Here, we investigate the interface between methylammonium lead tri-iodide (MAPbI) single crystals and commonly used high and low work function metals to achieve photon counting capabilities in a solid-state detector.
