A 5-month-old girl with transposition of the great arteries, ventricular septal defect, and pulmonary stenosis underwent the implantation of a 6-mm M Atrial Flow Regulator (Occlutech) over an 8-French delivery sheath for significant cyanosis and progressive restriction of the atrial septal defect, without adverse event for 6 months. The Atrial Flow Regulator device could improve blood mixing as a bridge to surgery.

In Estate Origins, Tomila Lankina sheds new light on the logic of persistence and resilience in the Russian social structure that shapes political possibilities in Russia to the present day. It is a wonderful and rewarding read on the historical origins of social requisites of democracy, such as greater civic activism and more pluralistic political competition. To understand variation in attitudinal and behavioral support for democracy in contemporary Russia, according to Lankina, we must go back to tsarist Russia’s estate institutions. A set of institutions that codified the rights and privileges of different social groups, the estates system created incentives for an eclectic and growing stratum of urban dwellers known as meshchane to invest in education while simultaneously fostering the creation of institutional “infrastructures”—professions, educational institutions, charitable, civic, and local governance bodies—that retained during the communist period a degree of autonomy vis-à-vis the state. This, Lankina argues, allowed the meshchane’s distinct value orientations to persist over time.

As with many other musical traits, the social environment is a key influence on the development of singing ability. While the familial singing environment is likely to be formative, its role relative to other environmental influences such as training is unclear. We used structural equation modeling to test relationships among demographic characteristics, familial environmental variables (early and current singing with family), vocal training, and singing ability in a large, previously documented sample of Australian twins (N = 1163). Notably, early singing with family, and to a lesser extent vocal training, predicted singing ability, whereas current singing with family did not. Early familial singing also mediated the relationship between sex and singing ability, with men who sang less with family during childhood showing poorer ability. Bivariate twin models between early familial singing and singing ability showed the phenotypic correlation was largely explained by shared environmental influences. This raises the possibility of a sensitive period for singing ability, with sociocultural expectations around singing potentially differentiating the developmental trajectories of this skill for men and women.

One feature of language is that we are able to make mistakes in our use of language. Amongst other sorts of mistakes, we can misspeak, misspell, missign, or misunderstand. Given this, it seems that our metaphysics of words should be flexible enough to accommodate such mistakes. It has been argued that a nominalist account of words cannot accommodate the phenomenon of misspelling. I sketch a nominalist trope-bundle view of words that can.

The study of the transmission of Latin texts has received an important new addition: the second volume of Stephen Oakley's Studies in the Transmission of Latin Texts, dedicated to the text of Vitruvius, the agricultural treatises of Cato and Varro, Porphyrio's commentary on Horace (or, rather, the abbreviated commentary transmitted under his name in manuscript V and younger related manuscripts), and Priscian's Latin translation of Dionysius’ Periegesis.1 In meticulous analyses and close work with manuscripts and incunables, Oakley traces the transmission of these texts and the genealogical relationships of individual (groups of) manuscripts as well as the progress of the scholarship on their transmission. The book is nicely illustrated by fifty-one images of some of the key manuscripts, and Oakley provides information of how to access these and others online as well.

Several authors have studied homomorphisms from first homology groups of modular curves to $K_2(X)$, with $X$ either a cyclotomic ring or a modular curve. These maps send Manin symbols in the homology groups to Steinberg symbols of cyclotomic or Siegel units. We give a new construction of these maps and a direct proof of their Hecke equivariance, analogous to the construction of Siegel units using the universal elliptic curve. Our main tool is a $1$-cocycle from $\mathrm {GL}_2(\mathbb {Z})$ to the second $K$-group of the function field of a suitable group scheme over $X$, from which the maps of interest arise by specialization.

The Society of Antiquaries of London’s collection of one hundred and seventy historical printing plates, dating from the early eighteenth to mid-nineteenth centuries, has long been a hidden gem. This paper presents the results of a research project initiated in 2022, focusing on the provenance, manufacture and bibliographical use of these plates. It explores the evolution of printing practices and the role of coppersmith stamps, shedding light on production methods and industry connections. The project involved digitising the plates for improved accessibility and preservation and cataloguing efforts to establish standardised guidelines for similar collections. Furthermore, the study uncovers the Society’s historical interest in maintaining and utilising these plates, providing valuable insights into past printing practices and collection management. This research enriches our understanding of the Antiquaries’ holdings through meticulous investigation and documentation and underscores the significance of exploring overlooked aspects of historical collections. It also calls for future research endeavours and collaborations to explore connections within the Society’s collections further and expand our knowledge of printing history. Overall, this study emphasises the importance of preserving and studying printing technology as valuable artefacts that contribute to our understanding of the past.
