Returning to the root : radical feminist thought and feminist theories of International Relations

Feminist International Relations (IR) theory is haunted by a radical feminist ghost. From Enloe's suggestion that the personal is both political and international, often seen as the foundation of feminist IR, feminist IR scholarship has been built on the intellectual contributions of a body of theory it has long left for dead. Though Enloe's sentiment directly references the Hanisch's radical feminist rallying call, there is little direct engagement with the radical feminist thinkers who popularised the sentiment in IR. Rather, since its inception, the field has been built on radical feminist thought it has left for dead. This has left feminist IR troubled by its radical feminist roots and the conceptual baggage that feminist IR has unreflectively carried from second-wave feminism into its contemporary scholarship. By returning to the roots of radical feminism we believe IR can gain valuable insights regarding the system of sex-class oppression, the central role of heterosexuality in maintaining this system, and the feminist case for revolutionary political action in order to dismantle it

Recent advances in C–H functionalisation through indirect hydrogen atom transfer

The functionalisation of C–H bonds has been an enormous achievement in synthetic methodology, enabling new retrosynthetic disconnections and affording simple synthetic equivalents for synthons. Hydrogen atom transfer (HAT) is a key method for forming alkyl radicals from C–H substrates. Classic reactions, including the Barton nitrite ester reaction and Hofmann–Löffler–Freytag reaction, among others, provided early examples of HAT. However, recent developments in photoredox catalysis and electrochemistry have made HAT a powerful synthetic tool capable of introducing a wide range of functional groups into C–H bonds. Moreover, greater mechanistic insights into HAT have stimulated the development of increasingly site-selective protocols. Site-selectivity can be achieved through the tuning of electron density at certain C–H bonds using additives, a judicious choice of HAT reagent, and a solvent system. Herein, we describe the latest methods for functionalizing C–H/Si–H/Ge–H bonds using indirect HAT between 2018–2023, as well as a critical discussion of new HAT reagents, mechanistic aspects, substrate scopes, and background contexts of the protocols

War junkies: Why foreign fighters are flocking to Ukraine

Ukraine is not the first place to come to mind when the term "foreign fighters" is used. But this Eastern European country has long been a destination for men from Western countries seeking the thrill of a battle they view as a fight for the future of Europe

The fetishization of sexual violence in international security

Recent international relations scholarship tends to view sexual violence, especially rape, as an exceptional—if not aberrant—phenomenon in war and armed conflict. Indeed, it often treats it as the sole form of gender-based violence capable of threatening international peace and security. I challenge the isolation of this particular form of gender violence in the study and governance of international security. I argue that the securitization of sexual violence produced its “fetishization” in international advocacy, policy, and scholarship. The stages of securitization operate as a process of fetishization by first, decontextualizing and homogenizing this violence; second, objectifying this violence; and third, affecting inter-unit relations through the “selling back” of sexual violence to actors involved in conflict. As such, my argument helps specify why securitization fails to adequately address an issue like sexual violence and often results in further retrenchment of disparate power relations

Militarized peace: understanding post-conflict violence in the wake of the peace deal in Colombia

After more than 50 years of war, in 2016, the Colombian government signed a historic peace accord with the country’s largest rebel group, the Revolutionary Armed Forces of Colombia (FARC)

Addressing function approximation error in actor-critic methods

In value-based reinforcement learning methods such as deep Q-learning, function approximation errors are known to lead to overestimated value estimates and suboptimal policies. We show that this problem persists in an actor-critic setting and propose novel mechanisms to minimize its effects on both the actor and the critic. Our algorithm builds on Double Q-learning, by taking the minimum value between a pair of critics to limit overestimation. We draw the connection between target networks and overestimation bias, and suggest delaying policy updates to reduce per-update error and further improve performance. We evaluate our method on the suite of OpenAI gym tasks, outperforming the state of the art in every environment tested
