Normatively, democratic constitutions should express how citizens want to govern themselves collectively. Little is known, however, about how citizens’ constitutional preferences can be elicited and aggregated in practice. An intuitively appealing approach is to allow various forms of popular participation during a constitution-making process, including a popular vote to accept or reject the draft constitution (Fishkin 2011). Based on the Chilean experience with democratic constitution making, this article identifies unanticipated and previously unexplored distortions that can lead to incongruence between the preferences of voters and representatives regarding the extent and direction of constitutional change.
A distinctive feature of 21st-century constitution making is the role assigned to citizens through various forms of direct participation, as well as special efforts to include groups underrepresented and marginalized in ordinary politics. The legitimacy of these processes increasingly requires a role for actors and groups previously excluded from crucial institutional decisions (Elster 1998; Fishkin 2011; Reuchamps and Welp 2023; Rubio-Marín 2020; Welp and Soto 2020). However, vested interests have proven challenging to overcome amid a global crisis of representation. The failed Chilean process of 2021–2022 provides valuable lessons about the triumphs and pitfalls of embracing an open approach to constitution making.
Style is easy to dismiss but crucial to understand, and Goodman's explanation of why style matters politically is one of the reasons that I, as a specialist in Roman rhetoric and political thought, appreciate his book. The absence I see in Goodman's book haunts my own work too; I have only just begun seriously applying myself to the task of rethinking and redress.
Research on public health, crime, and policing regularly discusses sex workers in Southeast Asia but rarely recognises them as agents of social and political activism. This paper shows that sex workers and their allies in Singapore and the Philippines have long and rich histories of challenging their criminalisation and stigmatisation through cultural activism, political advocacy, consciousness-raising, and the provision of direct services to fellow sex workers. Using feminist ethnography, including interviews and participant observation with Project X in Singapore and the Philippine Sex Workers Collective, this paper explores how sex work activists have strategically adapted to their political environments. In Singapore, they maintain resistance through ‘shape-shifting,’ working within state-sanctioned mechanisms, positioning themselves as public health service providers, and creating spaces for radical political advocacy. In the Philippines, where an anti-sex work position is more deeply entrenched within dominant social blocs, sex work activists aggressively criticise state policies on social media and in carefully vetted forums but remain strategically invisible to avoid exposure, harassment, misrepresentation, and prosecution. This paper looks at how sex work activists engage in claims-making — underscoring the differences in the political resonance of human rights in both countries — and interrogates how sex work activism challenges social hierarchies, especially concerning migrants and trans individuals. Overall, it contributes to a richer understanding of non-traditional forms of political activism in Southeast Asia and makes visible sex workers’ contributions to feminism and labour movements in the global south and non-Western contexts.
In the sixth chapter of his Tianzhu shiyi (天主實義, “The True Meaning of the Lord of Heaven”), Matteo Ricci offers a critique of the anti-intentionalistic thread that he detects in the Chinese philosophical tradition. In this brief essay, I offer an analysis of a noteworthy archery analogy that Ricci employs to describe the nature of ethical action as an intentional process with a conscious aim. I trace how Ricci skilfully combines Western and Chinese images and categories to craft this simile. Before that, I set the stage by offering some preliminary comments that contextualize Ricci's interest in the question of intentional vs. non-intentional conduct.
Viscous streaming is an efficient rectification mechanism to exploit flow inertia at small scales for fluid and particle manipulation. It typically entails a fluid vibrating around an immersed solid feature that, by concentrating stresses, modulates the emergence of steady flows of useful topology. Motivated by its relevance in biological and artificial settings characterized by soft materials, recent studies have theoretically elucidated, in two dimensions, the impact of body elasticity on streaming flows. Here, we generalize those findings to three dimensions, via the minimal case of an immersed soft sphere. We first improve existing solutions for the rigid-sphere limit, by considering previously unaccounted terms. We then enable body compliance, exposing a three-dimensional, elastic streaming process available even in Stokes flows. Such effect, consistent with two-dimensional analyses but analytically distinct, is validated against direct numerical simulations and shown to translate to bodies of complex geometry and topology, paving the way for advanced forms of flow control.
Expressions of social discontent that trigger deep political reform appear to be a sign of the times. Emerging political actors challenge delegitimized political elites with promises of a closer relationship with electorates, new rules to fight corruption, and more open access to the benefits of economic growth. Often, however, reforms in recent decades have weakened instead of strengthened democracy, leaving political systems less fair and more exclusive than before. The Chilean constitution-making process of 2021–2022 reasonably raised hopes for a different outcome.
Flow-induced vibration (FIV) of a flexible cylinder with a triangular cross-section, allowed to oscillate in the cross-flow, inline and torsional direction, is studied experimentally through water tunnel tests. The dynamic response of the cylinder was studied for three different angles of attack ($0^\circ, 30^\circ, 60^\circ$), at reduced velocities of 0.9–16.27, corresponding to Reynolds numbers of 364–3600. At the angle of attack of $0^\circ$, vortex-induced vibration at low reduced velocity was observed, which transitioned to galloping at higher reduced velocities. At the angles of attack of $30^\circ$ and $60^\circ$, galloping-type response was observed over the range of the reduced velocities tested. Our results show that the cylinder's torsional oscillation breaks the system's symmetry and affects the structural response at higher reduced velocities regardless of the angle of attack. The FIV response of the flexible triangular cylinder is distinct from that of a rigid flexibly mounted triangular cylinder due to torsional oscillation, spanwise flexibility and the two fixed boundary conditions limiting the amplitude of oscillation. Flow field analysis in the wake of the cylinder was done qualitatively and quantitatively using hydrogen bubble flow visualisation and time-resolved volumetric particle tracking velocimetry techniques, respectively. Our results show the existence of highly three-dimensional vortex structures in the wake of the cylinder. We studied the coupling between the vortex shedding modes in the wake of the cylinder and the structural vibration modes through the spatiotemporal mode analysis using the proper orthogonal decomposition technique to distinguish between different types of the FIV response observed.
This article draws on a variety of primary sources to first illustrate the rise of African abolitionism in the Fante region in the mid-nineteenth century and then situate local abolitionists in the context of colonial legal abolition in the Gold Coast. When the British abolished slavery in 1874, various Fante groups had been developing local anti-slavery views and strategies closely connected to the evolution of a Fante ethnic identity fashioned against the “barbaric” Asante. Tensions arose between the Fante intelligentsia, which spearheaded local abolitionism, and British colonial elites. The article examines the rise of local abolitionism among the coastal Fante through specific ideas, individuals, and events, and discusses subsequent dynamics in the “first age” (1874–1900) of colonial abolitionism in the Gold Coast. It shows that the 1874 abolition was opposed by members of the Fante anti-slavery movement not—as has been argued—because Fante intellectuals were pro-slavery or opposed to the idea of abolition, but because they held different visions of emancipation and were critical of British abolition laws that, unlike in the West Indies, did not compensate slaveowners.
The trilobite faunas that occur with the Steptoean Positive Isotope Carbon Excursion (SPICE) at Smithfield Canyon, Utah, have been reported, but not illustrated. Given the importance of the SPICE at this section for international correlations, the trilobites from new collections from the upper Nounan Dolomite to lower St. Charles Formation at Smithfield Canyon are reported herein and integrated with the previously reported taxa. Trilobite assemblages indicate that the upper Cedaria to the Ellipsocephaloides biozones (Miaolingian Series, Guzhangian Stage to Furongian Series, Jiangshanian Stage) are present stratigraphically below or above the SPICE.
Some of the taxa reported herein may represent new species, but they are not represented by well-enough preserved specimens and are left in open nomenclature. However, Kingstonia smithfieldensis n. sp. and Bromella utahensis n. sp. are named on the basis of common and well-preserved specimens.
New carbon isotope data from Smithfield Canyon from an overlapping section of the lower St. Charles Formation, that add to the overall shape of the SPICE curve, are presented. The new δ13C values above the Elvinia Biozone range from –0.36‰ to +1.5‰, confirming that the SPICE concludes within the Elvinia Biozone.
This paper explores American tariff politics and the embrace of protectionism within the Ohio Valley in the two decades following the War of 1812. During these years, residents of the western states navigated the emergence of steam transportation, a growing number of state-chartered banks, and intense population growth. This fueled an economic boom that went bust during the Panic of 1819. Western farmers, merchants, and manufacturers blamed harmful patterns of trade for this economic crisis, which bolstered a distinct regional identity that embraced a properly constructed restrictive tariff as a “western” measure. Consequently, the decade of the 1820s featured the most sustained period of conflict over the tariff issue in the antebellum era. This article examines western participation in conflicts over commerce and roots the political economy of trade policy in changing economic conditions that inspired distinct northern, southern, and western perspectives on trade and economic development. I conclude that both protectionist claims to economic nationalism and free trade embrace of international exchange overlook the individual assessments of local and regional markets that set the terms on which participants in the tariff debates of the early republic imagined future development.
The history of the accommodation of Najm al-Dīn Dāya's Persian work, Mirṣād al-ʿibād, in China sheds light on an array of social and intellectual forces that redrew and straddled earlier boundaries and definitions of Chinese Islam between the sixteenth and eighteenth centuries. This essay focuses on three main effects that the introduction of Mirṣād al-ʿibād had on the historical trajectory of early modern Chinese Islamic scholarship. It begins by pointing to the ways in which the introduction of the Mirṣād contributed to the reshaping of the Chinese Islamic canon by giving Persian Ṣūfī theology a central place and the heated debate that the process entailed. It then examines the methodological dilemmas surrounding the appropriate methods with which to investigate and scrutinize this difficult text, and the variety of reading practices and methods of translation that scholars have applied to do so. Finally, the essay examines the diverse readings and interpretations that the Chinese translations of this text have generated.
Affiliation with different religions can have different effects on practitioners’ trust in state institutions and in social actors. Based on a survey of 3,740 residents in Hong Kong in 2021, we examine the relationship between religious affiliation and believers’ trust in the political authorities in Beijing and Hong Kong and in civil actors in the city. We find that affiliation with traditional Chinese religions and Eastern religions has a positive and significant effect on believers’ trust in the political authorities, whereas belief in Western religions does not have such an effect. Affiliation with Western religions, however, has a stronger positive and significant effect on interpersonal trust and on tolerance for unconventional behaviour. These findings shed light on the interaction between the government and religious groups in Hong Kong after 1997.
Natural flyers and swimmers employ flexible wings or fins to propel. While the complex interaction between the foil with deformation and the surrounding non-steady fluid environment defines the propulsion performance of the propellers, elucidating the interaction mechanism through theoretical models earns much challenge. Based on elastokinetics and linear potential flow theory, this study proposes a simplified analytical model to clarify the kinematics and the propulsion performance of a flexible thin foil pitching in flow. The dynamical forces, including the inertial force of the foil and the non-steady fluid pressure, are used to determine the averaged deformation angle of the foil. Combining the averaged deformation angle and the prescribed driving pitching motion, the kinematics of the foil is resolved analytically. Based on the analytical expressions for the corresponding pitching motion, analytical relations among the physical parameters of the stiffness and the mass of the foil and the driving frequency are given to these critical conditions, including resonance of the flow–structure system, equal pitching amplitude between the flexible foil and the rigid counterpart, phase angle transition from ${\rm \pi}/2$ to $- {\rm \pi}/2$. Subsequently, the performance of the foil, including the thrust, the power and the propulsive efficiency, as a function of the flexibility of the foil are derived, together with the introduction of a bluff body type offset drag to the thrust. The formulated analytical theory, which matches nicely with previous reports, will help to interpret the effect of the flexibility and regulate the propulsive performance of the flexible foil when pitching in fluid.
In this paper, we study non-isochoric models for mixtures of solid particles, at high volume concentration, and a gas. One of the motivations for this work concerns geophysics and more particularly the pyroclastic density currents, whose dense basal parts are precisely mixtures of pyroclasts and lithic fragments and air. They are extremely destructive phenomena, capable of devastating urbanised areas, and are known to propagate over long distances, even over almost flat topography. Fluidisation of these dense granular flows by pore gas pressure is one response that could explain this behaviour and must therefore be taken into account in the models. Starting from a solid–gas mixing model and invoking the compressibility of the gas through a law of state, we rewrite the conservation of mass equation of the gas phase into an equation of the pore gas pressure whose net effect is to reduce the friction between the particles. The momentum equation of the solid phase is completed by generic constitutive laws, specified as in Schaeffer et al. (J. Fluid Mech., vol. 874, 2019, pp. 926–951) by a yield function and a dilatancy function. Therefore, the divergence of the velocity field, which reflects the ability of the granular flow to expand or compress, depends on the volume fraction, pressure, strain rate and inertial number. In addition, we require the dilatancy function to describe the rate of volume change of the granular material near an isochoric equilibrium state, i.e. at constant volume. This property ensures that the volume fraction, which is the solution to the conservation of mass equation, is positive and finite at all times. We also require that the non-isochoric fluidised model be linearly stable and dissipate energy (over time). In this theoretical framework, we derive the dilatancy models corresponding to classical rheologies such as Drucker–Prager and $\mu (I)$ (with or without expansion effects). The main result of this work is to show that it is possible to obtain non-isochoric and fluidised granular models satisfying all the properties necessary to correctly account for the physics of granular flows and which are well posed, at least linearly stable.
We investigated concurrent outbreaks of Pseudomonas aeruginosa carrying blaVIM (VIM-CRPA) and Enterobacterales carrying blaKPC (KPC-CRE) at a long-term acute-care hospital (LTACH A).
Methods:
We defined an incident case as the first detection of blaKPC or blaVIM from a patient’s clinical cultures or colonization screening test. We reviewed medical records and performed infection control assessments, colonization screening, environmental sampling, and molecular characterization of carbapenemase-producing organisms from clinical and environmental sources by pulsed-field gel electrophoresis (PFGE) and whole-genome sequencing.
Results:
From July 2017 to December 2018, 76 incident cases were identified from 69 case patients: 51 had blaKPC, 11 had blaVIM, and 7 had blaVIM and blaKPC. Also, blaKPC were identified from 7 Enterobacterales, and all blaVIM were P. aeruginosa. We observed gaps in hand hygiene, and we recovered KPC-CRE and VIM-CRPA from drains and toilets. We identified 4 KPC alleles and 2 VIM alleles; 2 KPC alleles were located on plasmids that were identified across multiple Enterobacterales and in both clinical and environmental isolates.
Conclusions:
Our response to a single patient colonized with VIM-CRPA and KPC-CRE identified concurrent CPO outbreaks at LTACH A. Epidemiologic and genomic investigations indicated that the observed diversity was due to a combination of multiple introductions of VIM-CRPA and KPC-CRE and to the transfer of carbapenemase genes across different bacteria species and strains. Improved infection control, including interventions that minimized potential spread from wastewater premise plumbing, stopped transmission.
This article uses Mbembe's concept of necropolitics as an analytical category to examine the representations of necropower in Squid Game. In the global “organ economy,” organ sellers decide to supply, and brokers then mediate between them and buyers. In contrast, South Korean loan sharks commodify delinquent debtors' organs by forcing them to sign a body waiver as collateral. Recent South Korean dramas have thematized this distinctive systemization of the black economy. Borrowing Lowenstein's “allegorical moment” concept, this article aims to illuminate representations of fluid necropower through children's games as a hinge between reality and the imaginary that invites viewers to dialectically evaluate death problems. The contestations of money and humanity synthetically emerge as necropower constantly moves among different entities: VIPs, a frontman, players, game rules, and money. This article claims that viewers process numerous allegorical moments created by the iconography of necropower and synthetically realize necropolitics and corporeality in Squid Game. Organ extractions and trade in episode two in particular represent “morbid spectacle” and the culmination of mammonism. This article analyzes scenes of death, games, the technique of killing, and esthetics to connect historical examples of the necropolitics that Mbembe draws on and to discuss representations of the organ trade in this recent Korean drama.
