Ralph Vaughan Williams's The Lark Ascending is a perennial favourite in the British classical music radio station Classic FM's ‘Hall of Fame’ poll. In spite of its apparent popularity, however, the work sits uncomfortably with the way revisionist critics and scholars have wanted to portray the composer. As an escapist piece of English musical pastoralism, The Lark undermines their preferred view of Vaughan Williams as a progressive or even ‘modernist’ participant in his artistic milieu. To combat this image, some critics and musicologists have argued for complex, harder-edged interpretations of the work that have little to no basis in the music's primary source materials or the composer's stated priorities in his own writings. Such emphases reflect a problem in recent revisionist literature, wherein traditionalist, nationalist, or Romantic aspects of Vaughan Williams's music are excessively downplayed (or re-situated) in favour of arguments that better support elite sensibilities. As a work consisting of accessible, melody-centric music, and following from a poem excerpt suggesting an idyllic scene, The Lark serves as a bulwark against revisionist overreach and a check against over-emphasis on trendy priorities.

Trait anxiety and attentional control are important factors related to depression symptoms. The study investigated how trait anxiety and attentional control predicted the trajectories of depression symptoms during the transition into early adolescence. The mediating effect of attentional control on the relationship of trait anxiety to the trajectories of depression symptoms was also examined. Children of 9 to 10 years were recruited at Time 1. Trait anxiety, attentional control, and depression symptoms were assessed at Time 1. Depression symptoms were measured at three follow-up assessments across 18 months. Latent class growth modeling revealed high (14.4%) and low (85.6%) trajectories of depression symptoms. Higher trait anxiety and lower attentional control predicted a higher likelihood of showing the trajectory of high depressive symptoms. Attentional control mediated the relationship of trait anxiety to the trajectory membership of depression symptoms. The findings had important implications for the association of trait anxiety with the trajectory membership of depression symptoms and highlighted the importance of attentional control in the development of depression symptoms for children with high trait anxiety.

Robots with multi-sensors always have a problem of weak pairing among different modals of the collected information produced by multi-sensors, which leads to a bad perception performance during robot interaction. To solve this problem, this paper proposes a Force Vision Sight (FVSight) sensor, which utilizes a distributed flexible tactile sensing array integrated with a vision unit. This innovative approach aims to enhance the overall perceptual capabilities for object recognition. The core idea is using one perceptual layer to trigger both tactile images and force-tactile arrays. It allows the two heterogeneous tactile modal information to be consistent in the temporal and spatial dimensions, thus solving the problem of weak pairing between visual and tactile data. Two experiments are specially designed, namely object classification and slip detection. A dataset containing 27 objects with deep presses and shallow presses is collected for classification, and then 20 slip experiments on three objects are conducted. The determination of slip and stationary state is accurately obtained by covariance operation on the tactile data. The experimental results show the reliability of generated multimodal data and the effectiveness of our proposed FVSight sensor.

The probability that an event will avalanche into an impairment of essential services constitutes a “systemic risk.” Owing to the inherent complexities of modern societies, the outbreak of a novel disease or the failure of a financial institution can rapidly escalate into an impact significantly larger than the initial event. Through the lens of complex system theory, this article draws a parallel between financial crises and disasters to contend that the regulatory framework for financial systemic risk is unequipped to address its fundamental dynamics. Epitomized by the market failure rationale, financial regulation is premised on a reductionist view that purports both systemic risk and law as external to the actions of market participants. Conversely, this article advances a twofold conceptual framework. First, it shows that systemic risk emerges from the same complex dynamics that generate the financial system. Second, it understands law as an agent of complexity, thus contributing to the emergence of finance and its inherent instability. Normatively, this conceptual framework reveals the limits of current regulatory approaches and constructs a holistic risk governance framework that is akin to the one adopted to govern disaster risks.

The frequency of growth increments in the tube wall of the Mesozoic and Cenozoic serpulids is in the range of modern species (i.e. 7–37 growth lines per 50 μm). The growth increments of serpulids do not show correlation with the water temperature and presumably cold water and warm water serpulid species are growing on average with similar speed in terms of number of growth lines per 50 μm. The large serpulid species have usually significantly larger growth increments than smaller species and presumably also grew faster than smaller species. The species with denser skeletons have lower growth rates than species with more porous skeletons. It is possible that serpulids do not have to calcify faster to produce thicker growth increments with lower density.

Public debates structure election cycles, feature in news media, and are privileged as a form of academic exchange. Yet, public debate is poorly understood from the perspective of political theory. While theorists often talk about “public debate,” they usually mean diffuse discussion on a topic in the public sphere. This article considers how literal public debates—multisided, publicly accessible and publicly oriented performances of reason-giving—may be normatively distinct from other forms of rhetoric. Drawing on the “constructivist turn” in the scholarship on representation and the philosophy of Gadamer, I offer a hermeneutical approach for assessing public debates. I argue that public debates do not merely provide a platform for opinions to be broadcast, they also purport to provide a representative spectrum of opinions. In so doing, they help to construct the borders of the public sphere itself. I conclude by considering the significance of protest to public debate.

We evaluated whether universal chlorhexidine bathing (decolonization) with or without COVID-19 intensive training impacted COVID-19 rates in 63 nursing homes (NHs) during the 2020–2021 Fall/Winter surge. Decolonization was associated with a 43% lesser rise in staff case-rates (P < .001) and a 52% lesser rise in resident case-rates (P < .001) versus control.

To avoid penalizing exporters that already paid carbon prices, the EU Carbon Border Adjustment Mechanism credits carbon taxes and Emissions Trading Schemes in third countries. By excluding instruments of traditional regulation (e.g. emission standards) and indirect carbon prices (e.g. fuel excise taxes) from this crediting mechanism, the EU is criticized for discriminating against countries that do not follow its climate model, in breach of international trade and climate law. This article seeks to nuance this criticism by arguing that the calculation of actual emissions (instead of default values) under the EU CBAM allows exporters to reflect compliance with foreign emission standards, and thus respects states' right to pursue emission reductions through traditional regulation. However, amendments of the CBAM Regulation are necessary to recognize the positive and negative impact of indirect carbon prices on decarbonization, and the role of carbon-crediting mechanisms in equalizing carbon costs in a more flexible and equitable way.

Platypnea-orthodeoxia syndrome is characterised by hypoxemia and dyspnoea while upright that resolves when supine, typically associated with an interatrial communication. We present a case of platypnea-orthodeoxia syndrome associated with a sinus venosus atrial septal defect in a patient with multiple possible aetiologies of hypoxemia, including COVID-19 infection. Cardiac catheterisation with provocative maneuvers confirmed the diagnosis and symptoms resolved following defect closure. We suggest that in patients with platypnea-orthodeoxia syndrome, it is useful to obtain haemodynamic data while supine and upright

For a graph $H$ and a hypercube $Q_n$, $\textrm{ex}(Q_n, H)$ is the largest number of edges in an $H$-free subgraph of $Q_n$. If $\lim _{n \rightarrow \infty } \textrm{ex}(Q_n, H)/|E(Q_n)| \gt 0$, $H$ is said to have a positive Turán density in a hypercube or simply a positive Turán density; otherwise, it has zero Turán density. Determining $\textrm{ex}(Q_n, H)$ and even identifying whether $H$ has a positive or zero Turán density remains a widely open question for general $H$. By relating extremal numbers in a hypercube and certain corresponding hypergraphs, Conlon found a large class of graphs, ones having so-called partite representation, that have zero Turán density. He asked whether this gives a characterisation, that is, whether a graph has zero Turán density if and only if it has partite representation. Here, we show that, as suspected by Conlon, this is not the case. We give an example of a class of graphs which have no partite representation, but on the other hand, have zero Turán density. In addition, we show that any graph whose every block has partite representation has zero Turán density in a hypercube.

The minimum number of idempotent generators is calculated for an incidence algebra of a finite poset over a commutative ring. This quantity equals either $\lceil \log _2 n\rceil $ or $\lceil \log _2 n\rceil +1$, where n is the cardinality of the poset. The two cases are separated in terms of the embedding of the Hasse diagram of the poset into the complement of the hypercube graph.
