This article discusses the thin socio-legal conceptualisation of the rule of law in Hungary. Employing a culturalist perspective, it first shows how the rule of law had a thin foundation prior to the Second World War in this country. Then, the contribution demonstrates how, contrary to previous understandings, even in the most advanced stages of rule of law building in Hungary, in the early 1990s, the resulting concept had been thin mainly focusing on institutional guarantees and legal certainty. The remaining part of the contribution then critically discusses whether and to what extent it is possible to use backsliding to frame the ongoing legal changes in Hungary.

Improving community attitudes and behaviours is core to improving inclusion for people with disability. To identify ways to achieve such change, we analysed data from qualitative interviews with sixty-one expert stakeholders in Australia, informed by our preceding literature review on effective interventions. We identified five themes describing factors with the potential to change attitudes and behaviours to improve inclusion and reduce discrimination: ensuring people with disability have active presence across all life domains; leadership by people with disability, together with organisational and governmental leadership that values the diverse contribution of people with disability; a holistic approach to policy and interventions that targets multiple levels of change; long-term and adequately resourced initiatives to achieve structural and sustained change; and commitment to measuring and monitoring change interventions, to inform decisions and maintain accountability.

Late Postclassic lowland Maya civic-ceremonial masonry architecture appears in two main configurations—temple assemblages and basic ceremonial groups—first identified at Mayapan. Around the Peten lakes, these two architectural complexes have been tied to northern immigrant Kowojs and Itzas, respectively, and their distributions map the varying control over the lakes by these two ethnopolities. Temple assemblages exhibit considerable variation in their structural components and arrangements throughout the lowlands, but they have not been studied comparatively. Here, we examine 14 temple assemblages at 12 lowland sites. We consider one of the two assemblages at Zacpeten (Sak Peten), Group A, to have been built by Kowojs, who asserted their identity and earlier (Late/Terminal Classic) ties to the site by reusing carved monuments. “Blended” assemblage Group C is more difficult to parse, but reflects cosmo-calendrical principles of statecraft and the builders’ and users’ broader ties to Mayapan and Topoxte.

As the need for collaboration across multiple organizations to deal with complex social issues such as poverty, crime, and public health grows, Public–Private Partnership (PPP) is of increasing importance. However, little is known about when and why private firms engage in such partnerships. Drawing on upper-echelon theory and the information-processing perspective, we highlight the importance of institutional knowledge and information embedded in CEO cross-sector work experience. We argue that such tacit knowledge and information enables CEOs to better identify the potential risks associated with PPPs. Consequently, CEOs with cross-sector work experience tend to be more cautious in participating in such partnerships, especially in developing economies like China, where private actors face greater information incompleteness concerning post-collaboration hazards due to the government's selective disclosure. Moreover, we develop a multi-moderator framework in which regional marketization and political connection alter the main effect by serving as supplementary information channels for private actors. A panel dataset of Chinese private listed firms from 2013 to 2021 provides strong support for our hypotheses. This study contributes to our understanding of the micro-foundation of PPP formation and draws attention to CEOs’ prior career experiences in different organizational forms.

A cycle C of a graph G is dominating if $V(C)$ is a dominating set and $V(G)\backslash V(C)$ is an independent set. Wu et al. [‘Degree sums and dominating cycles’, Discrete Mathematics 344 (2021), Article no. 112224] proved that every longest cycle of a k-connected graph G on $n\geq 3$ vertices with $k\geq 2$ is dominating if the degree sum is more than $(k+1)(n+1)/3$ for any $k+1$ pairwise nonadjacent vertices. They also showed that this bound is sharp. In this paper, we show that the extremal graphs G for this condition satisfy $(n-2)/3K_1\vee (n+1)/3K_2 \subseteq G \subseteq K_{(n-2)/3}\vee (n+1)/3K_2$ or $2K_1\vee 3K_{(n-2)/3}\subseteq G \subseteq K_2\vee 3K_{(n-2)/3}.$

Both Hungary and Poland have been in the spotlight regarding their democratic backsliding, with Executives exerting control over supposedly independent pillars of democracy, such as courts or the media. While the concerns about these countries also voiced by leaders of European institutions were similar, the resistance against the systematic erosion of judicial independence comes in different forms. Using comparative longitudinal case study methodology, this article shows that a defining characteristic in the potential, visibility and feasibility of what judges did or could do under the current threats depends on the role judicial associations, understood as representative collegial judicial bodies. More precisely, the format, organisation and operative tools of judicial associations contribute to their influence on prior judicial reforms and their capacity to withstand ongoing efforts in curtailing their independence from political actors. Empirically, the article reviews multiple judicial changes in the 1992–2015 period in both countries and assesses how judicial associations then shaped the divergent responses to recent attempts at limiting judicial independence. The differences in the legal framework, organisation and network reliance explains variance in resistance. Overall, the article broadens the theoretical and empirical framework for studying the role of courts and judges with considerations regarding professional association organisation and co-ordination, as a potential layer of studying judicial resistance.

Accurate online estimation of the payload parameters benefits robot control. In the existing approaches, however, on the one hand, only the linear friction model was used for online payload identification, which reduced the online estimation accuracy. On the other hand, the estimation models contain much noise because of using actual joint trajectory signals. In this article, a new estimation algorithm based on parameter difference for the payload dynamics is proposed. This method uses a nonlinear friction model for the online payload estimation instead of the traditionally linear one. In addition, it considers the commanded joint trajectory signals as the computation input to reduce the model noise. The main contribution of this article is to derive a symbolic relationship between the parameter difference and the payload parameters and then apply it to the online payload estimation. The robot base parameters without payload were identified offline and regarded as the prior information. The one with payload can be solved online by the recursive least squares method. The dynamics of the payload can be then solved online based on the numerical difference of the two parameter sets. Finally, experimental comparisons and a manual guidance application experiment are shown. The results confirm that our algorithm can improve the online payload estimation accuracy (especially the payload mass) and the manual guidance comfort.

The Choquard equation is a partial differential equation that has gained significant interest and attention in recent decades. It is a nonlinear equation that combines elements of both the Laplace and Schrödinger operators, and it arises frequently in the study of numerous physical phenomena, from condensed matter physics to nonlinear optics.

In particular, the steady states of the Choquard equation were thoroughly investigated using a variational functional acting on the wave functions.

In this article, we introduce a dual formulation for the variational functional in terms of the potential induced by the wave function, and use it to explore the existence of steady states of a multi-state version the Choquard equation in critical and sub-critical cases.

Recent research shows that, even under direct insertion, loan verbs are subject to constraints: for instance, they enter non-finite categories more readily than finite categories. To deepen our understanding of such loan word accommodation biases we investigate two contact situations to test whether biases hold in contact between closely related languages. A corpus study on Norse and French loan verbs entering Middle English compares the proportions of their finite and non-finite usage to gauge the impact of etymology and temporal distance to direct contact on loan integration. We identify significant bias towards non-finite use for both etymologies, but it is stronger for French than for Norse loan verbs. This suggests that biases are stronger in some contexts than in others: they are more prominent at a smaller temporal distance to direct contact and in contact between languages that are less closely related.

Medical practitioners, inevitably scattered across the country, need frequent periodicals to communicate the latest medical information. Journals are an essential component of the infrastructure of modern medicine, yet they were slow to achieve firm roots in Britain during the eighteenth century, with few sustained quarterly periodicals and the only attempt at a monthly lasting a year. Then in 1799, Richard Phillips, owner of the Monthly Magazine, published the Medical and Physical Journal, the first sustained monthly medical journal, which lasted for thirty-four years. Ever since, Britain has never been without a monthly or weekly general medical journal. Responding to the need for a strong commercial focus, the Journal used a magazine format which blended reviews and abstracts of already published material with original contributions and medical news, and it quickly achieved a national circulation by close engagement with all types of practitioners across the country.

Contrary to the historiography, the Journal was distinctly different from the contemporaneous monthly science journals. The key to success was two-way communication with all practitioners, especially the numerous surgeons and surgeon-apothecaries who were increasingly better trained and confident of their status. Much of the content of the Journal was written by these readers, and with rapid, reliable distribution and quick publication of correspondence, controversial topics could be bounced back and forth between all practitioners, including the distinguished. Initially, the editors tried to maximise circulation by avoiding any controversy, but this started to change in the first few years of the next century.

Hyper-redundant cable-driven manipulators (CDMs) are widely used for operations in confined spaces due to their slender bodies and multiple degrees of freedom. Most research focuses on their path following but not path planning. This work investigates a deep deterministic policy gradient (DDPG)-based path-planning algorithm for CDMs in multi-obstacle environments. To plan passable paths under many constraints, a DDPG algorithm is modified according to features of CDMs. To improve adaptability of planned paths, a specialized reward function is newly designed. In this function, such factors as smoothness, arrival time and distance are taken into account. Results of simulations and physical experiments are presented to demonstrate the performances of the proposed methods for planning paths of CDMs.

Arterial oxygen saturation in single ventricle patients is dependent on systemic cardiac output. Here, we describe a case of a newborn with single ventricle physiology and an unusual mechanism to explain poor cardiac output and cyanosis. This case highlights the importance of identifying and considering ventricular morphology and ventricular-ventricular interactions to understand clinical challenges.

This article critically examines the significance of the relationship between past and present for understanding liberal democratic values in the European context. The article starts by reflecting on the terms used to evaluate the apparent decline in the rule of law in Europe, including ‘backsliding’. It argues that these terms are indicative of a conceptual framework of analysis that includes a temporal dimension but is only partly historical, demonstrating a presentist focus and a perception of the past as a separate period. The article links this perception with the conceptual construction of the rule of law itself, as well as national and transnational narratives about it, which evoke Europe’s non-democratic past as a definitional point of reference that is distinct from the present. Using examples of the legacies of Europe’s dark legal past, the article highlights the artificial nature of this distinction for a range of systems with differing historical experiences. The article argues that interpreting the past in terms of segmented and sequential temporal periods is conceptually contestable and it draws on the philosophy of history to show how the past can instead be understood to have ‘sedimentary’ layers and to endure over time. Ultimately, the article argues that the relationship between law’s past and law’s present needs to be reconceptualised in terms of metaphorical ‘fault lines’ in the rule of law, to acknowledge the potentially disruptive effects of history and to facilitate a critical reimagining of the rule of law’s theoretical and factual foundations.
