Premenstrual exacerbation of existing mental illnesses (PME) is a condition where symptoms of mental disorders worsen during the luteal phase. Unlike premenstrual syndrome or premenstrual dysphoric disorder, PME is poorly recognised, with misdiagnoses and inadequate treatment. Understanding the brain impact of gonadal hormone fluctuations in PME is crucial.

Despite the turn to the right of many national governments, including France, the 2024 theatre festival in Avignon programmed by a new director, Tiago Rodrigues, delivered feminist, internationalist, antiracist, and progressive works. The lineup showed both his courage to defend what he believes in and his support of exceptional artists who share his political passions (Caroline Guiela Nguyen, Mohamed El Khatib, Lola Arias, Marta Górnicka, Séverine Chavrier, Baro d’evel, among others).

Heyting’s intuitionistic predicate logic describes very general regularities observed in constructive mathematics. The intended meaning of the logical constants is clarified through Heyting’s proof interpretation. A re-evaluation of proof interpretation and predicate logic leads to the new constructive Basic logic properly contained in intuitionistic logic. We develop logic and interpretation simultaneously by an axiomatic approach. Basic logic appears to be complete. A brief historical overview shows that our insights are not all new.

Although long-run economic performance has improved primarily through a decline in the rate and frequency of shrinking rather than through an increase in the rate of growing, most analysis of economic development has focused on increasing the rate of growing. We examine the forces making for a reduction in the rate of shrinking. The main proximate factors considered are (1) structural change, (2) technological change, (3) demographic change, and (4) stabilization policy. We conclude by considering institutions and institutional change as the key ultimate factors behind the reduction in shrinking, showing how they operate through political stability.

Unable to perform the perceived demands of his gender—unable to have sex—in 2014 the incel Elliot Rodger devised a performance of ruthless cruelty. His mass murder, a now habituated performance of US American masculinity, was preceded by an autobiographical text. Recounting his pursuit of a consummate manhood, Rodger’s manifesto reveals the consequential movement from narrative to performance, from genre to gender, from a discourse of discontent to a violent dramaturgy of masculinity.

Dr. Tom Beauchamp wrote multiple seminal articles that influenced bioethics, research ethics, and animal ethics. But his influence extends beyond his academic scholarship. Here we honor Dr. Beauchamp’s contributions as a scholar, mentor, and teacher.

This editorial describes common methodological obstacles, including the healthy user bias, that are encountered in research studying the link between hormonal contraceptive use and depression and provides considerations for future directions.
