Housing is a critical part of every state’s infrastructure. However, in most advanced economies the state no longer builds very much of it, leaving it instead to private housebuilders. Because of their control over the supply of land, and the barriers to entry into the housebuilding industry, private housebuilders have potentially major structural power over the state. At the same time, private housebuilders are also tied to their land, and face other barriers to exit, thus limiting their ability to relocate capital elsewhere. Drawing on a range of secondary data sources, including earnings calls transcripts, annual reports and government policy documents, this paper demonstrates how the three largest volume housebuilders in England leveraged their structural power to shape the mortgage market support schemes that were introduced in the aftermath of the Global Financial Crisis. These schemes have since underpinned their exceptional levels of profitability. We conclude, though, that far from being an absolute resource, this structural power was only enabled by the prevailing neoliberal, home-owning Anglo-liberal ‘growth model’ in which these housebuilders were embedded.

The newly designed HVE gas interface enables the AMS measurement of carbon samples in CO2 form. The CO2, e.g. resulting from the sample combustion in an elemental analyzer, is adsorbed in a zeolite trap and subsequently transferred to a motor-driven syringe. Once diluted with He, the gas mixture is transferred into the ion source of the AMS system. A carbon ion beam is formed in the ion source and mass-analyzed by the AMS system, resulting in 13C/12C and 14C/12C isotopic ratios. The HVE gas interface features two traps and two syringes to maximize the sample throughput, which results in more than 10 samples per hour. The first performance results of CO2 gas sample AMS measurements that were performed with the HVE gas interface in combination with the HVE 210 kV AMS system are presented in this paper. The measurements show that the gas interface contribution to the 14C/12C background is in the 10–15 level and to the precision is at or below 1%.

In 1789, the Academy of Ancient Music replaced Benjamin Cooke with Samuel Arnold as its musical director. This article offers a detailed analysis of an autograph copy of the address Cooke delivered to the Academy responding to their action, and of a letter to Cooke from Arnold countering accusations made regarding his conduct in the affair. Both documents are annotated by Henry Cooke, who used them in writing a biography of his father. These documents enable a new understanding of the significant changes made within the Academy in the 1780s and of the reasons Academy subscribers replaced Cooke with Arnold.

We study whether the increased adoption of available automation technologies allows economies to avoid the negative effect of aging on per capita output. We develop a quantitative theory in which firms choose to which extent they automate in response to a declining workforce and rising old-age dependency. An important element in our model is the integration of two capital types: automation capital that acts as a substitute to human labor, and traditional capital that is a complement to labor. Empirically, our model's predictions largely match data regarding automation (robotization) density across OECD countries. Simulating the model, we find that aging-induced automation only partially compensates the negative growth effect of aging in the absence of technical progress in automation technology. One reason is that automated tasks are no perfect substitutes for non-automated tasks. A second reason is that automation raises the interest rate and thus inhibits positive behavioral reactions to aging (later retirement and investment in human capital). Moreover, increased automation generates a falling net labor share of income and rising welfare inequality. We evaluate alternative policy responses to cope with this inequality.

In this issue of BJPsych Advances Siddaway explores the challenges of assessing and treating post-traumatic stress disorder (PTSD) and complex PTSD. In this commentary I reflect on those challenges, not least of which is the need for a thorough understanding of different approaches to diagnoses. The very concept of diagnostic classification systems can be problematic, but when used sensitively they can aid communication, assessment and treatment. The relatively new diagnosis of complex PTSD may serve as a more accurate and more useful description of some psychological difficulties, leading to better treatment decisions. Good assessment, leading to accurate diagnosis, useful formulation and effective treatment takes time, and adequate resources should be allocated. Professionals can help patients to make well-informed choices about treatment options and they should offer evidence-based treatments without unnecessary delay.

Statius’ Thebaid inverts the traditional positive reading of agricultural work. In the account of the founding moments of Thebes, the poet remains faithful to what is documented in the extant Greek and Roman literary material. However, as this article argues, Statius introduces two significant innovations with respect to his thematic precedents. First, Cadmus the founder is explicitly and emphatically pointed out as guilty of the internecine struggle that results from his farming. Second, he does not limit himself to sowing the soil but, previously, he plows it. The ploughing motif, although pivotal in the myth of Jason's trials in Cholchis, only appears referred to Cadmus in Ovid's Metamorphoses (3.104–5), albeit in a very succinct form. As will be examined, Statius amplifies the Ovidian suggestion, programmatically conferring negative connotations to this motif (tillage, bull, yoke, furrow, etc.) throughout his epic. Cadmus’ ill-fated tillage is unambiguously presented as the origin of the curse of Thebes and as the root cause of the present fratricidal war between Eteocles and Polynices. The dire fruits which agricultural labour invariably produces in the Cadmean farmlands echo Lucanean Thessalian fields from whose furrows, contaminated by the blood of Roman combatants, grow polluted crops. The blame that Statius places on the shoulders of Cadmus the farmer, the relationship he establishes between farming and fratricidal war, and his insistence on the perverse effects of agricultural work transform mythic Thebes into an exemplar of fratricidal Rome as apt as Lucan's historical Thessaly.

This article explores the potential for the greater infusion of well-being concerns into the teaching of history in UK HEIs. Drawing upon results from a survey of over 100 current undergraduates in one UK History department, alongside a scoping study of well-being provision provided by history departments or their equivalent in about ninety UK HEIs, this article considers ways in which well-being can be promoted through the teaching and learning strategies of historians. The article discusses the meaning of the term ‘well-being’ and asks why historians have sometimes been reluctant participants in the ‘eudaemonic turn’. The negativity bias of history as an endeavour, and the potential for understanding the past to enhance or diminish an individual's sense of well-being is discussed, as is the value of historicising the concept of well-being itself. The case for integrating well-being as a key element in the degree-level study of history is made, and the article concludes by urging all HEI history practitioners to consider the value of curricular infusion and mapping the design and delivery of their modules onto the New Economics Foundation's ‘five ways to well-being’.

In this paper, we consider a range of trans-inclusive approaches to gender concepts and how they relate to the world, from family resemblance theories to conceptual engineering. In so doing, we shall also examine several concepts that are analogous to gender and other controversial and not-so-controversial concepts, such as “vegan cheese” and “adoptive parents.” Having assessed their merits and demerits, we argue that our gender concepts are not fixed in stone but, rather, evolve alongside human practices and behavior.

Florence, Bibliotheca Riccardiana MS 996 is an interesting miscellany of late fifteenth- and early sixteenth-century texts. Among the manuscript's curious content is Dominici Cerbonii Tifernatis TERtheus Magus (‘The Triple God Magus of Domenico Cerbonio from Città di Castello’, fols 7r–10v). Evenly written in a neat humanistic cursive, with rubrication for the titles and a single marginal note (interpreted here as a stage direction), these folios form an account, in Latin prose and verse, of a necromantic ritual performed by members of the Roman Academy in which the shades of Cicero and Virgil are conjured from the pagan underworld to admire the Renaissance city. It is tempting to take this pagan rite as proof of the charges of heresy levelled at members of the Academy for which they were arrested and imprisoned in Castel Sant'Angelo on the orders of Pope Paul II Barbo (r. 1464–71) during Lent, 1468. However, this paper argues that the texts are evidence of a dramatic performance with scenery (or at least a theatrical backdrop) staged by the members of the reformed Academy as part of their annual celebrations of the Palilia (or Parilia) on Rome's birthday 21 April c. 1501.

The gastrointestinal microbiota plays a crucial role in host nutrition and health. While culture-independent techniques have advanced microbial research, they often overlook low-abundance bacteria in the microbial community. Furthermore, empirical studies and mechanistic research rely on bacterial isolates obtained through culturing. The introduction of culturomics in 2012 significantly advanced culture-dependent techniques, contributing to microbial research. However, these methods remain labor-intensive, time-consuming, and costly, similar to traditional culture methods. This review provides an overview of the contributions of culturomics, summarizes procedures for optimizing sample and culture processes, and offers guidance on utilizing metagenomic data to enhance culturomics workflows. By collating and synthesizing these developments, this review aims to provide valuable insights into improving the practicality and productivity of culturomics for capturing gastrointestinal bacterial communities.

This work proposes a novel grasp detection method, the Efficient Grasp Aware Network (EGA-Net), for robotic visual grasp detection. Our method obtains semantic information for grasping through feature extraction. It efficiently obtains feature channel weights related to grasping tasks through the constructed ECA-ResNet module, which can smooth the network’s learning. Meanwhile, we use concatenation to obtain low-level features with rich spatial information. Our method inputs an RGB-D image and outputs the grasp poses and their quality score. The EGA-Net is trained and tested on the Cornell and Jacquard datasets, and we achieve 98.9% and 95.8% accuracy, respectively. The proposed method only takes 24 ms for real-time performance to process an RGB-D image. Moreover, our method achieved better results in the comparison experiment. In the real-world grasp experiments, we use a 6-degree of freedom (DOF) UR-5 robotic arm to demonstrate its robust grasping of unseen objects in various scenes. We also demonstrate that our model can successfully grasp different types of objects without any processing in advance. The experiment results validate our model’s exceptional robustness and generalization.

Three fish blood flukes (Aporocotylidae Odhner, 1912) infect mullets (Mugiliformes: Mugilidae): Cardicola mugilis Yamaguti, 1970 and Plethorchis acanthus Martin, 1975 infect striped mullet, Mugil cephalus Linnaeus, 1758 in the Central Pacific Ocean (Hawaiian Islands) and Brisbane River (Australia), respectively; Cardicola brasiliensis Knoff & Amato, 1992 infects Lebranche mullet, Mugil liza Valenciennes, 1836 from the Southwestern Atlantic Ocean (Brazil). White mullets were cast-netted from the mouth of Deer River, a coastal saltmarsh of Mobile Bay, in the north-central Gulf of Mexico and examined for blood fluke infections. Specimens of Mugilitrema labowskiae Warren & Bullard n. gen., n. sp. were found infecting the endocardial surface and inter-trabecular spaces of the atrium, ventricle, and bulbous arteriosus. The new genus and species differ from all other aporocotylids by having the combination of two post-caecal testes, a uterus with straight ascending and descending portions, and a common genital pore. The 28S analysis recovered the new species and P. acanthus as sister taxa and Aporocotylidae as monophyletic. Carditis associated with intense infections comprised endocardial hyperplasia, resulting in a thickened cardiac endothelium. Probable dead or deteriorating eggs in the myocardium were encapsulated by granulomas composed of epithelioid histiocytes. Live eggs infected the afferent artery of gill filaments and were associated with varied hyperplasia of the overlying epithelium and haemorrhaging from the afferent artery in high-intensity infections. The new species is the first aporocotylid infecting a mullet from the northwestern Atlantic Ocean and only the second description of demonstrable endocarditis attributed to an adult fish blood fluke infection.

The present analysis focuses on the material component of time, the devices used for measuring and counting it. The biological basis for subjective, experiential time is first reviewed, as are early strategies found cross-culturally for measuring and counting time objectively. These strategies include timekeeping by natural phenomena, using tallies to keep track of small periods of time, harnessing shadows for daily and annual time, and visualizing time with clocks and calendars. The conclusion then examines how such timekeeping devices might influence the conceptualization of time.

We perform a multifractal analysis of homological growth rates of oriented geodesics on hyperbolic surfaces. Our main result provides a formula for the Hausdorff dimension of level sets of prescribed growth rates in terms of a generalized Poincaré exponent of the Fuchsian group. We employ symbolic dynamics developed by Bowen and Series, ergodic theory and thermodynamic formalism to prove the analyticity of the dimension spectrum.

The Secretarybird Sagittarius serpentarius is a charismatic raptor of the grasslands and open savannas of Africa. Evidence of widespread declines across the continent has led to the assessment that the species is at risk of becoming extinct. Southern Africa was identified as a remaining stronghold for the species, but the status of this population requires reassessment. To determine the status of the species in South Africa, Lesotho, and Eswatini, we analysed data from a citizen science project, the Southern African Bird Atlas Project (SABAP). We implemented novel time-to-detection modelling, as well as summarisation of changes in reporting rates, using standard metrics, to determine the trajectory of the population. To cross-validate our findings, we used data from another citizen science project, the Coordinated Avifaunal Roadcounts (CAR) project. While our results were in agreement with previous studies that have reported significant declines when comparing SABAP1 (1987–1992) and SABAP2 (2007 and onwards), all analysis pathways that examined data within the SABAP2 period only, as well as CAR data from this period, failed to show an alarming declining trend over this more recent time period. We did, however, find some evidence for decreases in Secretarybird abundance in urban grid cells. We used random forest models to predict probability of occurrence, as well as probability of abundance (reporting rates) for the assessed region and provided population estimates based on these analysis pathways. Continued monitoring and conservation efforts are required to guard this population stronghold.
