The formal theory of monads shows that much of the theory of monads can be developed in the abstract at the level of 2-categories. This means that results about monads can be established once and for all and simply instantiated in settings such as enriched category theory.

Unfortunately, these results can be hard to reason about as they involve more abstract machinery. In this paper, we present the formal theory of monads in terms of string diagrams — a graphical language for 2-categorical calculations. Using this perspective, we show that many aspects of the theory of monads, such as the Eilenberg–Moore and Kleisli resolutions of monads, liftings, and distributive laws, can be understood in terms of systematic graphical calculational reasoning.

This paper will serve as an introduction both to the formal theory of monads and to the use of string diagrams, in particular, their application to calculations in monad theory.

Using 60 interviews with a range of minority law students and early career legal professionals (primarily differentiated by race, gender identity, religion, and disability), this Article illuminates the cruciality of empirical Critical Race Theory to understand individual deviance within the legal profession and develops a framework – blasé – for considering interactional violence that is not legally or socially cognizable as discrimination but still causes harm. These data reveal that discrimination was minimized and denied to varying degrees for all minority respondents. However, for genderqueer respondents whose identities had not achieved a high degree of sociolegal legibility, these denials had low contestability and were often without contrition. Unlike microaggressions which might have resonance in common cultural parlance as operationalizations of structural violence, what distinguishes blasé discrimination, I argue, is the ordinariness of the act in interactional parlance alongside its relative unlikeliness to be seen as problematic when confronted. It is this possibility of defense and justification in the face of being challenged that makes blasé and its ambiguous parameters worthy of our attention in identity jurisprudence. This exploration of the blasé response to discrimination sheds light on the opportunities available for revealing structural inequalities when analysis begins from the perspectives of peripheral actors.

United Nations peacekeeping is experiencing a generational shift as several large missions downsize and close. Amid this change, this essay considers the future of the Protection of Civilians (PoC) mandate, which has been a priority of UN peacekeeping since it was first authorized twenty-five years ago. It argues that PoC has evolved significantly, expanding from a narrow focus on physical protection from immediate threats to a holistic approach that includes establishing a protective environment. It suggests that while the PoC mandate has proven effective in reducing violence, the future is fraught with four significant challenges: waning state commitment to UN peacekeeping, the fragmentation of global peace and security mechanisms, shifting local perceptions in a rapidly changing information landscape, and mounting disillusionment among UN personnel. This essay contends that these obstacles underscore the inherently political nature of PoC, where power dynamics and perceptions profoundly impact mission success. As peacekeeping missions scale back, PoC remains essential but increasingly precarious, demanding strategic adaptability and sustained commitment. Ultimately, the essay argues that without renewed political and institutional dedication, PoC’s effectiveness—and the UN’s credibility—will be difficult to uphold in the face of evolving conflict dynamics and geopolitical shifts.

This article proposes and estimates a tractable, arbitrage-free valuation model for corporate coupon bonds that includes a more realistic recovery rate process. Most existing studies use a recovery rate process that is misspecified because it includes recovery for coupons due after default. Misspecification errors from assuming recovery on all coupons can be substantial; they increase with recovery rates, coupons, maturity, and default probabilities. For a large sample of market transactions, i) our model has lower pricing errors than one assuming recovery on all coupons and ii) the magnitude of our model’s outperformance is linked to misspecification errors from assuming recovery on coupons.

Fusing the aesthetics of futurity with the lush beauty of the natural world, planned eco-city developments like Forest City and Penang South Islands, both in Malaysia, promise luxury enclaves against climate change and the environmental stressors of existing cities. This article analyzes CGI architectural renderings used to promote and sell eco-city projects in Southeast Asia. Eco-city renderings, we argue, produce semio-capitalistic value by translating the familiar concepts of “green,” “eco-friendly,” and “sustainable” into something far more inchoate: feelings. They do so through their supersaturation with signs of greenness in a design strategy we label “semiotic overdetermination.” Selling “green” as a feeling, eco-city renderings capitalize on present-day anxieties over urban decay and commodify “the ecological” as a rich resource of pleasurable qualitative experiences. The result, we contend, is to reinforce a neoliberal mode of subjectivity that equates consumption with somatics and reduces climate responsibility to individual consumer decisions.

This paper provides an account of a specific operation – the removal of the thymus gland (thymectomy) to treat the rare neurological condition myasthenia gravis – from its first performance in 1936, by the American surgeon Alfred Blalock, to the publication in 2016 of an international multicentre randomised controlled trial (RCT) of the technique. Thymectomy was the subject of a transatlantic controversy in the 1950s, in which the main players were the English surgeon Geoffrey Keynes, and American neurologists and surgeons from New York, Boston, and the Mayo Clinic. The resolution of this controversy involved the use of increasingly sophisticated statistical techniques, but also crucially other influences including the social transformation of thoracic surgery, and competition between the leading American centres. The consensus achieved after this controversy was challenged in the late 1970s, eventually prompting the implementation of a trial acceptable to twenty-first-century evidence-based medicine. This account will demonstrate that surgical innovation in the period covered required increasing attention to the statistical basis of patient selection and outcome evaluation; that the processes of technical innovation cannot be regarded as separate from developments in the professional culture of surgery, and that one of the consequences of these changes has been the gradual eclipse of the prestigious autonomous surgeon.

This paper presents an innovative eight-pass laser amplifier design that effectively utilizes polarization and angular multiplexing, enjoying high gain, high extraction efficiency and compact layout. To optimize the design parameters, a general spatiotemporal model for a multi-pass amplifier is established that accounts for beam passages in different angles, and the predicted output energy and gain distribution agree well with the experimental results. The multi-pass amplifier scales the seed energy of 120 mJ to 5 J at 10 Hz and 3 J at 50 Hz, with the beam quality within three times the diffraction limit.

This article introduces the Special Issue ‘South–South Security Cooperation and the (Re)making of Global Security Governance’. The contributions explore security-driven South–South interactions across the globe, assessing empirical, theoretical, and normative aspects. Our aim is to decentre debates on global security governance, traditionally focused on Northern-led cooperation, and to move beyond simplistic and simplifying assessments of South–South engagements. The Special Issue particularly highlights the ambiguities of South–South security cooperation, including varying degrees of global North involvement and differing interpretations of ‘security’ and ‘South–South’ among the involved actors. The contributions examine the practical outlook, normative consequences, and embeddedness of these cooperations within global hierarchies, and their implications for global security governance. This article sets the stage for this endeavor. Unpacking the categories ‘South’, ‘security’, and ‘cooperation’, we first provide a working definition of South–South security cooperation. Next, we offer a historical perspective, emphasising the role of legacy effects, institutional structures, geopolitical junctures, and international hierarchies in shaping South–South security cooperation. The concluding section presents the contributions to the special issue and discusses the implications of South–South security cooperation for understanding contemporary changes in global security governance.

Soricidae is the most species-rich eulipotyphlan family since the Pliocene. Numerous Late Miocene soricids and plesiosoricids are well known from southern Europe. Localities from central Europe, despite being rare, historically have yielded better preserved material that reveals a great diversity. We here add to this existing record with the description of eight species from MN9- to MN12-aged localities of Slovakia (Paenelimnoecus repenningi, Paenesorex bicuspis, Isterlestes aenigmaticus n. gen. n. sp., Crusafontina endemica, Crusafontina kormosi, Amblycoptus jessiae, Asoriculus gibberodon, Petenyia dubia), alongside one species of Plesiosoricidae (Plesiosorex evolutus). The early occurrence of A. gibberodon and A. jessiae, the occurrence of Paenesorex, and the identification of Isterlestes aenigmaticus n. gen. n. sp., reinforce the hypothesis that the Pannonian region (south-eastern central Europe) was a source area for several soricid taxa (Allosoricinae, Anourosoricini, Soricini) during the Late Miocene.

Puerto Rico’s seven hundred miles of coastline are the most dynamic, biodiverse, heavily populated, and hotly contested part of the archipelago. Hurricanes beat the island from the ocean side while luxury tourist developments encroach from the land. These forces converge in the zona marítimo terrestre (ZMT), which includes littoral areas and navigable portions of waterways in which, according to Puerto Rican law, tides and the biggest waves from storms can be felt. This clunky legal term, notable for its shifting and affective dimension, has become part of everyday conversations and creative practices in contemporary Puerto Rico, but no academic study has considered its cultural significance. This article brings together insights from the fields of environmental justice and environmental humanities to propose that works of art and literature in the ZMT are autogestiones acuáticas, or independently imagined and managed shoreline activities that contest coastal displacement and articulate a decolonial sense of place within nonsovereign dynamics.

Attending to our responsibility to the dead in our present historical moment of danger, this lecture stages three distinct reading experiments in “living together with the dead” with special attention to Palestine and Algeria. The first scene contemplates the times of war and death that constitute what Jalal Toufic refers to as “the withdrawal of tradition past a surpassing disaster.” The second scene explores artistic resurrection in literature by examining antiphonic burial during colonial war while juxtaposing philosophical conceptions of the relationship between death, burial, and history writing. I thus elaborate a concept of death as non-secular and theological, and of history writing as a form of anamnesis that inhabits the isthmus between the Terrestrial realm and the realm of the Unseen. The final scene is a meditation on poetry under conditions of colonial and postcolonial catastrophe. Throughout, theology and poetry serve as provocations to the discipline of history.

Involuntary retirement has negative effects on an individual’s health and satisfaction with life. However, it remains unknown whether the recent European policy shift from early retirement towards extending working lives has impacted retirement voluntariness.

This study examines how socio-demographic factors affect retirement voluntariness, which is classified as ‘involuntary’ (e.g. being laid off), ‘voluntary’ (e.g. wanting to spend more time with family) or ‘regular’ (e.g. reaching the state pension age). The analysis is based on SHARE data (Survey of Health, Ageing and Retirement in Europe), covers ten European countries and differentiates between two retirement cohorts (1994–2004 and 2005–2015) during which the policy shift took place.

At the individual level, we find that gender and socio-economic status correlate with retirement voluntariness. At the company level, the sector of employment and job tenure also show an association with retirement voluntariness. The results indicate that, between the two cohorts, the share of those who experience their retirement as ‘regular’ has increased, while the share with ‘involuntary’ retirement has decreased. However, these shifts differ by educational groups, with a stronger increase of voluntary retirement for those with high education, suggesting a rise in social inequalities in retirement-transitions, likely owing to an accumulation of (dis)advantages over the lifecourse.
