The close relationship between the “Shiji jie” (Exposition of Historical Records) chapter of the Yi Zhoushu (Remaining Zhou Documents) and the “Wangzheng” (Portents of Destruction) chapter of the Han Feizi has long been recognized, but prior to this, the precise nature of the connection has been unexplored. This article presents a comparative study structured around an annotated translation of these two texts. The “Shiji jie” describes how King Mu of Zhou fell asleep and dreamed of a set of instructions for how to avoid the mistakes made by other dynasties and states that led to their decline and fall. This “mirror for princes” text is thought to have inspired Han Fei to create his own version, which has traditionally been read as a series of abstract warnings, describing situations which could lead to disaster for the monarch. This article argues that what Han Fei was actually doing was presenting a series of riddles for the reader to guess, each of which alludes to a specific historical event. The “Wangzheng” thus reframes the “Shiji jie” in terms of both style and content, creating a new literary work.
Evaluating pauses in natural speech is a promising strategy for improving reliability, validity, and efficiency in assessing cognitive functions in people with mild cognitive impairment (MCI) and Alzheimer’s dementia (AD).
Method:
We conducted a quantitative meta-analysis of studies employing automated pause analysis. We included measures of speaking rate for comparison.
Results:
We identified 13 studies evaluating pause measures and 8 studies of speaking rate in people with MCI (n’s = 276 & 109, respectively) and AD (n’s = 170 & 81, respectively) and healthy aged controls (n’s = 492 & 231, respectively). Studies evaluated speech across various tasks, including standard neuropsychological, reading, and free/conversational tasks. People with AD and MCI showed longer pauses than controls at approximately 1.20 and 0.62 standard deviations, respectively, though there was substantial heterogeneity across studies. A more modest effect, of 0.66 and 0.27 SDs, was observed between these groups in speech rate. The largest effects were observed for standardized memory tasks.
Conclusions:
Of the many ways that speech can be objectified, pauses appear particularly important for understanding cognition in AD. Pause analysis has the benefit of being face valid, interpretable in ratio format as a reaction time, tied to known socio-cognitive functions, and relatively easy to measure, compute, and interpret. Automation of speech analysis can greatly expand the assessment of AD and potentially improve early identification of one of the most devastating and costly diseases affecting humans.
In the recent history of private law theory, the task of restoring interpersonal justice to a position of chief importance has been undertaken by those who draw from the wellsprings of Kantian philosophy. But in defining the domain of interpersonal justice, Kantians have also narrowly confined it. In this article I offer a post-Kantian approach, taking reference from a method well established in political and moral philosophy, but yet to make a comprehensive impact on private law: contractualism. Contractualism anchors what we owe each other in the notion of interpersonal justification, offering a fresh understanding of persons, nexuses and relational reasoning. I show how this approach tackles key questions in private law – its institutions of empowerment, primary entitlements, remedial norms and practices, and the division of labour between public and private spheres – in a manner preferable to Kantian theory.
Sri Lanka’s Indigenous Vedda community, also known as Vanniyalaththo, has profound relationships with nature that are not recognized by the country’s colonial history and, subsequently, its Western-influenced legal framework. This article explores how the gap between relational Vedda laws and state-based law in Sri Lanka can be bridged. It suggests that the emerging paradigms of legal personhood and Rights of Nature, which acknowledge the more-than-instrumental values of nature, can serve as a starting point for bridging this gap. By exploring the relational ontologies of Vedda law, this article advocates broader recognition of Vedda worldviews within the existing state-based law in Sri Lanka and highlights the role of Indigenous communities as non-state actors in shaping more-than-human governance.
This paper investigates a continuous-time multidimensional risk model with stochastic returns driven by a geometric Lévy process, where each main claim is accompanied by a random number of delayed claims. By employing a framework of multivariate regular variation for claim sizes and allowing for arbitrarily dependent claim-number processes, we conduct asymptotic analyses for two types of ruin probabilities. Numerical examples are used to demonstrate the accuracy of our asymptotic estimates.
Whilst surface-stress integration remains the standard approach for fluid force evaluation, control-volume integral methods provide deeper physical insights through functional relationships between the flow field and the resultant force. In this work, by introducing a second-order tensor weight function into the Navier–Stokes equations, we develop a novel weighted-integral framework that offers greater flexibility and enhanced capability for fluid force diagnostics in incompressible flows. Firstly, in addition to the total force and moment, the weighted integral methods establish, for the first time, rigorous quantitative connections between the surface-stress distribution and the flow field, providing potential advantages for flexible body analyses. Secondly, the weighted integral methods offer alternative perspectives on force mechanisms, through vorticity dynamics or pressure view, when the weight function is set as divergence-free or curl-free, respectively. Thirdly, the derivative moment transformation (DMT)-based integral methods (Wu et al., J. Fluid Mech. vol. 576, 2007, 265–286) are generalised to weighted formulations, by which the interconnections among the three DMT methods are clarified. In the canonical problem of uniform flow past a circular cylinder, weighted integral methods demonstrate advantages in yielding new force expressions, improving numerical accuracy over original DMT methods, and enhancing surface-stress analysis. Finally, a force expression is derived that relies solely on velocity and acceleration at discrete points, without spatial derivatives, offering significant value for experimental force estimation. This weighted integral framework holds significant promise for flow diagnostics in fundamentals and applications.
Congenital junctional ectopic tachycardia is a rare arrhythmia that poses significant management challenges. This report presents a case of neonatal-onset congenital junctional ectopic tachycardia treated with cedilanid, amiodarone, and propafenone but persisted in episodes. Sinus rhythm was restored following the initiation of ivabradine therapy. The review of the literature indicates that ivabradine demonstrates efficacy in the treatment of paediatric junctional ectopic tachycardia, particularly in refractory cases, without significant side effects. These findings suggest that ivabradine has broad applications in the treatment of refractory arrhythmias.
Les recherches récentes montrent que les femmes en politique sont particulièrement exposées à l’hostilité en ligne. Lors des élections provinciales de 2022 au Québec, plusieurs politiciennes ont été victimes de menaces et d’abus en ligne et des cas similaires ont été observés à travers le Canada. Face à cette prévalence, cet article propose un cadre théorique féministe, s’appuyant sur les travaux de Nancy Fraser et le féminisme intersectionnel, dans le but de mieux comprendre les diverses formes de cyberviolence subies par les politiciennes et leurs effets sur leur participation politique. En combinant justice sociale et oppressions croisées, l’article offre une analyse des dynamiques de pouvoir et souligne l’importance de contrer ces violences pour préserver la démocratie et les droits fondamentaux des femmes.
This population-based cross-sectional study investigated the complex interplay of factors influencing high ultra-processed food (UPF) consumption among Brazilian adolescents using a hierarchical socio-ecological model. Data from 100 028 adolescents (13–17 years) enrolled in public and private schools nationwide were collected via self-administered questionnaires from the 2019 National School Health Survey. High UPF consumption was defined as ≥ 7 subgroups consumed on the previous day based on the NOVA classification. Poisson regression adjusted for complex sampling and hierarchical structure identified prevalence ratios (PR) for associated factors. High UPF consumption was significantly associated with younger age (PR = 1·22; 95 % CI 1·11, 1·34), regular breakfast consumption (PR = 1·32; 95 % CI 1·23, 1·42), regular screen time during meals (PR = 1·36; 95 % CI 1·27, 1·45), frequent UPF purchases at and around school (PR for canteen: 1·57; 95 % CI 1·43, 1·72; street vendors: 1·71; 95 % CI 1·55, 1·89), higher maternal education (PR 1·23, 95 % CI 1·12, 1·36) and lower parental supervision (PR 1·34, 95 % CI 1·11, 1·62). Living in the South (PR 1·50, 95 % CI 1·34, 1·69), Southeast (PR 1·30, 95 % CI 1·17, 1·44) and Midwest regions (PR 1·21, 95 % CI 1·09, 1·34) also correlated with higher consumption. Conversely, high body satisfaction and attending private school showed an inverse association. These findings underscore the intricate, multilevel influences on UPF consumption among Brazilian adolescents. Integrated interventions, spanning schools, family environments and public policies are crucial for promoting healthier eating habits and preventing obesity in this vulnerable population.
Loss of signals from substantia nigra (SN) and locus coeruleus (LC) on neuromelanin (NM)-sensitive sequences of MRI is reported as a potential biomarker in patients with Parkinson’s disease (PD) and related diseases. This scoping review aims to consolidate current knowledge on MRI techniques to visualize and quantify these signals and their clinical applications in PD. Publicly available databases were searched for original studies using MRI to quantify NM in PD and other related disorders. Different studies were compared based on MRI sequence, quantification techniques and correlations with clinical scores. Furthermore, studies on genetic forms of PD and prodromal PD were also evaluated and compared. The most common MRI sequences used were T1-weighted sequences and gradient echo sequences. Different studies used different quantitative measures such as signal-to-noise ratio, contrast-to-noise ratio and contrast ratio. Morphometric evaluations such as volume and area of the SN and LC signals were also used. Most studies showed evidence of significant difference in the signals in different stages of PD compared to controls both at the SN and LC. There were significant correlations between the SN and LC signals and clinical scores. Hence, quantification of these signals may be reliable in diagnosis and disease monitoring in PD. The relative ease of signal quantification and widespread availability of MRI may make it a quantitative surrogate biomarker.
The merging of two turbulent fronts without mean shear is investigated by direct numerical simulations. The turbulent streams are created by prescribing instantaneous velocity fields from precursor simulations of homogeneous isotropic turbulence (HIT) as inlet conditions for spatially evolving turbulent merging. The fronts are initially separated by a distance $H$ and convected with a uniform free stream velocity $U_{\infty }$. The inlet turbulence intensity varies in the range of $0.24 \leqslant u^{\prime}/U_{\infty } \leqslant 0.47$, while the inlet Taylor-scale Reynolds number is in the range of $151 \leqslant \textit{Re}_{\lambda } \leqslant 317$. As the flow develops in the streamwise direction, two distinct regions are identified: (i) an initial linear decay region, where the two turbulent fronts gradually approach each other without noticeable interaction; and (ii) a rapid decay region, where the opposing turbulent fronts influence one another and eventually merge. The flow statistics collapse once the streamwise coordinate is rescaled as $x^{+} = (x/H) (u^{\prime}/U_{\infty })$, suggesting that the merging location is imposed by large scales. An analysis conditioned to the developing turbulent/non-turbulent interfaces (TNTIs) reveals that, within the merging region, conditional mean enstrophy profiles deviate from those observed in ‘classical’ TNTIs, indicating a locally more homogenous flow. Within this region of interaction, the surface area of the TNTI increases while the volume of irrotational fluid steadily decreases, resulting in the generation of fine-scale structures. These findings support that turbulent merging is a multiscale process, where both the largest and smallest scales of motion intervene.
The paper examines job quality in South Korea by applying a novel wellbeing-based approach to defining ‘bad jobs’, extending methodology previously validated in European labour markets. The study analyses Korean Working Conditions Survey (2014–2023) data to investigate the relationship between job quality and worker wellbeing. The analysis reveals a significant discontinuity in the marginal effects of job quality on wellbeing at the bottom decile, where improvements yield distinctly larger wellbeing gains for workers moving above this threshold, providing empirical support for this approach to defining ‘bad jobs’. The prevalence of bad jobs shows a declining trend between 2014 and 2023, reflecting both economic growth and policy interventions. While the sectoral distribution of bad jobs shows similarities with European patterns, distinctive features emerge in South Korea’s labour market structure, characterised by the unique role of large business conglomerates (chaebols) and institutional arrangements. This study represents the first application of a wellbeing-based approach to defining bad jobs in an Asian context, demonstrating both its international applicability and the importance of national context in understanding the patterns of bad jobs. The findings carry significant implications for labour market policy in South Korea’s rapidly evolving economy, particularly for addressing persistent disparities in job quality across different segments of the labour market.
Goldstern showed in [7] that the union of a real-parametrized, monotone family of Lebesgue measure zero sets has also Lebesgue measure zero, provided that the sets are uniformly $\boldsymbol {\Sigma }^1_1$. Our aim is to study to what extent we can drop the $\boldsymbol {\Sigma }^1_1$ assumption. We show that Goldstern’s principle for the pointclass $\boldsymbol {\Pi }^1_1$ holds. We show that Goldstern’s principle for the pointclass of all subsets is consistent with $\mathsf {ZFC}$ and show its negation follows from $\mathsf {CH}$. Also we prove that Goldstern’s principle for the pointclass of all subsets holds both under $\mathsf {ZF} + \mathsf {AD}$ and in Solovay models.
