The non-archosauriform archosauromorph Dinocephalosaurus orientalis was first described from the Upper Member of the Guanling Formation (late Anisian, Middle Triassic) of Guizhou Province by Li in 2003 on the basis of a complete articulated skull and the first three cervical vertebrae exposed in dorsal to right lateral view. Since then, additional specimens have been discovered in southwestern China. Here, five newly discovered specimens are described for the first time, and redescriptions of the holotype IVPP V13767 and another referred specimen, IVPP V13898, are provided. Together, these permit the description of the complete skeleton of this remarkable long-necked marine reptile. The postcranial skeleton is as much as 6 metres long, and characterised by its long tail and even longer neck. The appendicular skeleton exhibits a high degree of skeletal paedomorphosis recalling that of many sauropterygians, but the skull and neck are completely inconsistent with sauropterygian affinities. The palate does not extend back over the basisphenoid region and lacks any development of the closed condition typical of sauropterygians. The arrangement of cranial elements, including the presence of narial fossae, is very similar to that seen in another long-necked archosauromorph, Tanystropheus hydroides, which at least in part represents a convergence related to an aquatic piscivorous lifestyle. The long and low cervical vertebrae support exceptionally elongate cervical ribs that extend across multiple intervertebral joints and contribute to a ‘stiffening bundle of ribs’ extending along the entire ventral side of the neck, as in many other non-crocopodan archosauromorphs. The functional significance of the extraordinarily elongate neck is hard to discern but it presumably played a key role in feeding, and it is probably analogous to the elongate necks seen in pelagic, long-necked plesiosaurs. Dinocephalosaurus orientalis was almost certainly a fully marine reptile and even gave birth at sea.

In two letters, Pliny and Trajan discuss a petition sent to the governor by the guild of athletes concerning their rewards after winning contests (Plin. Ep. 10.118–19). In his request, Pliny refers to a regulation by which Trajan had settled the rights of the victorious athletes in regard to their home cities. In his response, Trajan repeats the case with slight variations. The two letters pose both philological and historical difficulties, which this article aims to solve. The relevant passage in Trajan's letter is corrupt. As scholarship has misunderstood the historical background of the letters, no satisfying solution for the restoration of the text has been found to date. The argumentation of this article is twofold. First, it offers a new reading of the corrupt passage in the emperor's letter which respects both the textual transmission and the historical situation. Second, it is argued that the two letters refer to a Trajanic law which settled the regulations of iselastic contests for the first time, but left some details undecided. In sum, this article proposes a new reading of a damaged passage in Plin. Ep. 10.119 as well as offering a historical commentary on agonistic activities in imperial Asia Minor.

Kanban is a framework that is commonly used in the technology sector and other industries to help teams work more effectively, but it has not been widely adopted in LIS contexts. As many of us continue to adapt to hybrid workplaces, kanban could prove to be a useful tool for organising work and communicating. In this article Laura Griffiths and Alice Tyson of the IALS Library explain how Kanban boards work and offer a case study of how a Kanban board was used in a recent project at the IALS Library. The article also discusses the wider value of kanban to the LIS sector.

The first quasars at the Reionisation Epoch, z ∼ 6-7.5, probe the early stages of supermassive black holes and host galaxy assembly. In this paper, we present recent results, exploiting VLT, ALMA and NOEMA observations, that allow us to constrain the onset of strong black hole feedback, the dust properties and star formation rates in high redshift quasars with unprecedented accuracy. These results highlight the strategic importance of ALMA high frequency (i.e. Band 9 and 8) observations to obtain a reliable overview of the host galaxy and supermassive black hole growth out to the highest redshifts.

Through an ecological approach to creative practice (henceforth ecomprovisation), this project deals with the expansion of creative strategies applicable to everyday contexts. Within ubiquitous music (ubimus), we target the convergence of sonification methods with the application of ecological models within the context of comprovisation. These conceptual frameworks inform the technological and aesthetic approaches applied in the making of Markarian 335. We describe the creative procedures and the implications of the design choices involved in this artwork. The contributions and shortcomings of our ecomprovisational approach are situated within the context of the current efforts to foster expanded creative possibilities in ubimus endeavours.

Political scientists have largely come to a consensus that “most citizens are politically uninformed” (Delli Carpini and Keeter 1997), but even with increased attention to state-level representation and electoral behavior, political scientists know surprisingly little themselves regarding what Americans know about state politics. Past studies of state political knowledge examine narrow domains of knowledge and make few comparisons between individuals’ understanding of national and state politics. To provide a more comprehensive account of Americans’ state political knowledge, I conducted a novel national survey that included over 30 political knowledge questions. In a descriptive and exploratory analysis, I show Americans demonstrated more knowledge about who their Governor is but less knowledge about who represents them in the state legislature, state government institutions, and the state economy, particularly compared to their knowledge of federal politics. The different levels of political knowledge across different domains and levels of government raise concerns for statehouse democracy and should be considered before testing theories at the state level. To guide future research and surveys, I identify political knowledge questions that discriminate well between those who know little, some, and a lot about state politics across different domains of political knowledge.

The Sun and solar-type stars exhibit irregular cyclic variations in their magnetic activity over long time scales. To understand this irregularity, we employed the flux transport dynamo models to investigate the behavior of one solar mass star at various rotation rates. To achieve this, we have utilized a mean-field hydrodynamic model to specify differential rotation and meridional circulation, and we have incorporated stochastic fluctuations in the Babcock–Leighton source of the poloidal field to capture inherent fluctuations in the stellar convection. Our simulations successfully demonstrated consistency with the observational data, revealing that rapidly rotating stars exhibit highly irregular cycles with strong magnetic fields and no Maunder-like grand minima. On the other hand, slow rotators produce smoother cycles with weaker magnetic fields, long-term amplitude modulation, and occasional extended grand minima. We observed that the frequency and duration of grand minima increase with the decreasing rotation rate. These results can be understood as the tendency of a less supercritical dynamo in slow rotators to be more prone to produce extended grand minima. We further explore the possible existence of the dynamo in the subcritical regime in a Babcock–Leighton-type framework and in the presence of a small-scale dynamo.
