We introduce a description of passive scalar transport based on a (deterministic and hyperbolic) Liouville master equation. Defining a noise term based on time-independent random coefficients, instead of time-dependent stochastic processes, we circumvent the use of stochastic calculus to capture the one-point space–time statistics of solute particles in Lagrangian form deterministically. To find the proper noise term, we solve a closure problem for the first two moments locally in a streamline coordinate system, such that averaging the Liouville equation over the coefficients leads to the Fokker–Planck equation of solute particle locations. This description can be used to trace solute plumes of arbitrary shape, for any Péclet number, and in arbitrarily defined grids, thanks to the time reversibility of hyperbolic systems. In addition to grid flexibility, this approach offers some computational advantages as compared with particle tracking algorithms and grid-based partial differential equation solvers, including reduced computational cost, no Monte-Carlo-type sampling and unconditional stability. We reproduce known analytical results for the case of simple shear flow and extend the description of mixing in a vortex model to consider diffusion radially and nonlinearities in the flow, which govern the long time decay of the maximum concentration. Finally, we validate our formulation by comparing it with Monte Carlo particle tracking simulations in a heterogeneous flow field at the Darcy (continuum) scale.
According to Kant, it is possible to differentiate between legitimate and illegitimate laws by means of a certain formal procedure. His criterion for the legitimacy of a draft law is whether or not it corresponds to the ‘General Will’ of a people. The test question Kant has in mind is this: could a people give its consent to a proposed particular law? This chapter discusses the question of how this ‘General Will Test’ (GWT) is related to the Categorical Imperative (CI). As it will turn out, normatively valid laws are justified, in Kant’s view, by the fact that their content is established in a significantly non-ideal way, by a quasi-CI, namely the GWT. Thus, an intermediary position between the two mutually exclusive standard interpretations of Kant’s political philosophy is defended: the ‘derivation reading’ and the ‘separation reading’.
The employer provided everything – wages, housing, post office, parks, canteens. Such a model of the “company town,” where a single corporation dominates in multiple capacities as employer, landlord, service provider, and quasi-regulator over a dwelling area, has endured across borders and time. The term can portray textile mills in eighteenth-century England or coal and steel towns in early twentieth-century America just as fittingly as it does today’s network of “supply chain cities” that span East and Southeast Asia and beyond. This chapter studies Inter-Asia’s supply chain cities – in particular, manufacturing sites in East and Southeast Asia. More than physical spaces, these sites represent a form of legal entrepôt, created by law and capable of shaping laws and norms through diverse pathways, including regulatory fragmentation and coordinated advocacy. In comparison with another gilded-age moment of industrial development – early twentieth-century United States – these modern company towns exemplify the uniqueness of Inter-Asia’s corporate forms, exercise of power, and regional integration.
To carry out its action, the Israeli state must ensure the support of its Western allies and contain criticism from its adversaries or new partners in the Arab world, whose public opinion is highly critical of Israel. To achieve these political objectives, Tel Aviv implemented an unprecedented communication strategy to disseminate its narratives and content to the widest possible audience.
This chapter examines the introduction of new lay participation systems in Asian countries. Focusing on Russia, South Korea, Japan, and Taiwan, I explore the social and political contexts and goals of the policymakers that motivated the incorporation of citizen decision-making into the legal systems of these countries. In each of the four countries, the adoption of new systems of lay participation occurred during periods of political democratization. Those who argued in favor of citizen involvement hoped that it would promote democratic self-governance, create more robust connections between the citizenry and the government, and improve public confidence in the courts. Policymakers drew on the experiences of other countries, including other Asian nations, to develop a distinctive model that incorporated some features of lay participation systems elsewhere, and modified them to suit the specific circumstances of their own countries.
The existence of democratic systems of government threatens the legitimacy of authoritarian regimes. Democracy presents unique opportunities and vulnerabilities, including public debate and free expression, which nefarious actors can exploit by spreading false information. Disinformation can propagate rapidly across social networks and further authoritarian efforts to weaken democracy. This research discusses how Russia and China leverage online disinformation across contexts and exploit democracies’ vulnerabilities to further their goals. We create an analytical framework to map authoritarian influence efforts against democracies: (i) through longer term, ambient disinformation, (ii) during transitions of political power, and (iii) during social and cultural divides. We apply this framework to case studies involving Western democracies and neighboring states of strategic importance. We argue that both China and Russia aim to undermine faith in democratic processes; however, they bring different histories, priorities, and strategies while also learning from each other and leveraging evolving technologies. A primary difference between the countries’ disinformation against democracies is their approach. Russia builds on its longstanding history of propaganda for a more direct, manipulation-driven approach, and China invested heavily in technological innovation more recently for a permeating censorship-driven approach. Acknowledging it is impossible to know disinformation’s full scope and impact given the current information landscape, the growing international ambition and disinformation efforts leveraged by authoritarian regimes are credible threats to democracy globally. For democracies to stay healthy and competitive, their policies and safeguards must champion the free flow of trustworthy information. Resilience against foreign online disinformation is vital to achieving fewer societal divides and a flourishing information environment for democracies during peaceful – and vulnerable – times.
How do the dual trends of increased misinformation in politics and increased socioeconomic inequality contribute to an erosion of trust and confidence in democratic institutions? In an era of massive misinformation, voters bear the burden of separating truth from lies as they determine how they stand on important issue areas and which candidates to support. When candidates engage in misinformation, it uncouples the already weak link among vote intentions, candidate choice, and policy outputs. At the same time, high levels of economic inequality and social stratification may contribute to lower levels of institutional trust, and the correspondingly more insular socioeconomic groups may experience misinformation differently. Social policy, as a policy area intentionally designed to alleviate risk and redistribute resources, thus becomes a special case where the effects of misinformation and socioeconomic inequality may be crosscutting and heightened.
This chapter explores, in a roundabout way, whether Kant’s legal philosophy relies on his mature ethics of autonomy and respect. The normativity of the law must be externally enforced by coercive measures. The proportionate and credible threat that transgressions will be punished acts as a deterrent and make the rights of individuals comparatively secure – the law is occasionally broken. Now, the Kantian state does not concern itself with why in particular citizens break or comply with the law. In that sense, Kant’s philosophy of law does not rely on his ethical theory or moral psychology. But agents must be in a position to comply with the law. They must face a meaningful choice, which can only be secured by the availability of the motive of ethics: respect for the law. Without respect, agents would be exposed to prudential considerations only. Those who break the law take their criminal act to be prudentially justified. Viewed from this limited perspective, their actions turn out to be imprudent if they are punished for them. But punishability and imprudence are different. So, making what the law prohibits properly illegal requires an ethical foundation after all.
Dense granular flows exhibit both surface deformation and secondary flows due to the presence of normal stress differences. Yet, a complete mathematical modelling of these two features is still lacking. This paper focuses on a steady shallow dense flow down an inclined channel of arbitrary cross-section, for which asymptotic solutions are derived by using an expansion based on the flow’s spanwise shallowness combined with a second-order granular rheology. The leading-order flow is uniaxial with a constant inertial number fixed by the inclination angle. The streamwise velocity then corresponds to a lateral juxtaposition of Bagnold profiles scaled by the varying flow depth. The correction at first order introduces two counter-rotating vortices in the plane perpendicular to the main flow direction (with downwelling in the centre), and an upward curve of the free surface. These solutions are compared with discrete element method simulations, which they match quantitatively. This result is then used together with laboratory experiments to infer measurements of the second-normal stress difference in dense dry granular flow.
This chapter contends that writing is a practice of taking responsibility for restitution. I focus on works by W. G. Sebald, Alexander Kluge and Heimrad Bäcker. In his last speech before his death, Sebald stated ‘only in literature […] can there be a form of restitution’. I look at the way two of his novels, The Emigrants (1992) and Austerlitz (2001), are literally put together and examine how they correspond to this restitutive obligation. In addition, I examine short stories by Alexander Kluge from 1962 and 2013 and the form of their response to the NS regime. I also show how the concrete poetry of Heimrad Bäcker in his work transcript (1986) demonstrates a writing practice of fragmentation and citation in its confrontation with the NS legal archives. The works in this chapter span three different literary genres and all show a struggle with the persona of the author and the practice of writing – its possibilities and its responsibilities – in the aftermath of the NS regime and the Holocaust.
The world faces an era of ‘permacrisis’, marked by overlapping challenges such as climate change, conflicts, economic instability, and recurrent disease outbreaks, which disrupt health systems and deepen inequalities. Primary Health Care (PHC) is vital for addressing immediate health needs and social determinants, fostering resilience, and promoting equity during such crises. This opinion piece highlights PHC’s unique role in ensuring essential services, reducing barriers to care, and integrating health with broader social and environmental policies. In conflict-affected and climate-impacted regions, PHC supports community resilience, promotes health equity, and adapts to systemic shocks. Investing in PHC infrastructure, empowering community health workers, early disease detection, promoting climate-adaptive health practices and delivering integrated care can advance health for all. PHC offers a sustainable pathway to resilient health systems capable of navigating the complexities of a rapidly changing world.
We define a class of amenable Weyl group elements in the Lie types B, C, and D, which we propose as the analogs of vexillary permutations in these Lie types. Our amenable signed permutations index flagged theta and eta polynomials, which generalize the double theta and eta polynomials of Wilson and the author. In geometry, we obtain corresponding formulas for the cohomology classes of symplectic and orthogonal degeneracy loci.
The introduction briefly reviews the growing significance of remote work and then presents the volume’s holistic and interactive approach to studying the impact and regulation of this employment approach. With a rooting in methodological discussions and institutional analysis, this approach assumes that the full impact of remote work can only be understood by identifying and analyzing ways in which different employment forms and their regulation interact with one another in complex ways. Thus, for example, an employee’s work is not only remote or located in the traditional workplace but it is also part time or full time and so forth. Moreover, each of these conditions may be only partial in nature. Not only in empirical reality but also in the regulation of work, types of employment and their regulation interact with one another in ways that the volume identifies, explains and theorizes, opening up new understandings. The introduction then lays out the thematic concerns and main arguments of the chapters authored by a distinguished set of contributors.
Accurate estimation of dark matter halo masses for galaxy groups is central to studies of galaxy evolution and for leveraging group catalogues as cosmological probes. In this work, we present a comprehensive evaluation and calibration of two complementary halo mass estimators: a dynamical estimator based on a modified virial theorem (MVT) and an empirical summed stellar mass to halo mass relation (sSHMR), which uses the summed mass of the three most massive group galaxies as a proxy for halo mass. Using a suite of state-of-the-art semi-analytic models (SAMs; Shark, SAGE, and GAEA) to produce observationally motivated mock light-cone catalogues, we rigorously quantify the accuracy, uncertainty, and model dependence of each method. The MVT halo mass estimator achieves negligible systematic bias (mean $\Delta = -0.01$ dex) and low scatter (mean $\sigma = 0.20$ dex) as a function of the predicted halo mass, with no sensitivity to the SAM baryonic physics. The calibrated sSHMR yields the highest precision, with mean $\Delta = 0.02$ dex and mean $\sigma = 0.14$ dex as a function of the predicted halo mass but exhibits greater model dependence due to its sensitivity to varying baryonic physics and physical prescriptions across the SAMs. We demonstrate the application of these estimators to observational group catalogues, including the construction of the empirical halo mass function and the mapping of quenched fractions in the stellar mass–halo mass plane. We provide clear guidance on the optimal application of each method: the MVT is recommended for GAMA-like surveys ($i \lt 19.2$) calibrated to $z \lt 0.1$ and should be used for studies that require minimal model dependence, while the sSHMR is optimal for high-precision halo mass estimation across diverse catalogues with magnitude limits of $Z \lt 21.2$ or brighter and to redshifts of $z \leq 0.3$. These calibrated estimators will be of particular value for upcoming wide-area spectroscopic surveys, enabling robust and precise analyses between the galaxy–halo connection and the underlying dark matter distribution.
Under the assumption that the adjusted Brill-Noether number$\widetilde {\rho }$ is at least $-g$, we prove that the Brill-Noether loci in ${\mathcal M}_{g,n}$ of pointed curves carrying pencils with prescribed ramification at the marked points have a component of the expected codimension with pointed curves having Brill-Noether varieties of pencils of the minimal dimension. As an application, the map from the Hurwitz scheme to ${\mathcal M}_g$ is dominant if $n+\widetilde {\rho } \geq 0$ and generically finite otherwise, settling a variation of a classical problem of Zariski.
In the second part of the paper, we study the analogous loci of curves in Severi varieties on $K3$ surfaces, proving existence of curves with nongeneral behaviour from the point of view of Brill-Noether theory. This extends previous results of Ciliberto and the first-named author to the ramified case. We apply these results to study correspondences and cycles on $K3$ surfaces in relation to Beauville-Voisin points and constant cycle curves.
