Relative to the centuries preceding and following it, the tenth century a.d. in Mesoamerica is poorly understood by scholars. Although there is some regional variation in the timing of these events, archaeologists commonly ascribe a pattern of political decline, dynastic collapse, or social reorganization to this period. Paradoxically, increasing interregional interactions and emergent market exchange networks are also characteristics of macroregional patterns during the tenth century. These contradictory phenomena contribute to confusion surrounding interpretations of this transitional time. This article contributes a comparative dataset from systematic archaeological investigations of El Coyote, a monumental center in the lower Cacaulapa valley, Department of Santa Barbara, Honduras. The late occupational phase contains evidence for Early Postclassic chronological markers, including Tohil Plumbate pottery; obsidian from Pachuca, Hidalgo; and copper metallurgy. Calibrated radiocarbon assays with a 2σ error place these contexts between a.d. 710 and 1040, with a clustering of intercepts circa a.d. 900. These results are consistent with a pattern described throughout Mesoamerica and demonstrate that despite variation in the use of cultural terminology—Epiclassic, Terminal Classic, or Early Postclassic—there is uniformity in the timing of this macroregional interaction.

Nine hundred and ninety-two (992) specimens of Pseudocyclops lerneri Fosshagen, 1968 (Copepoda: Pseudocyclopidae) were collected from the largest South Atlantic coral reef, Abrolhos bank (17°20′–18°10′S; 38°35′–39°20′W). Specimens were distinguished from other Pseudocyclops spp. by a close examination of the female and male fifth leg. This is the first record of the family Pseudocyclopidae in the South Atlantic. We further indicate that the low number of studies on this species, and as a consequence, the poorly understood ecology of Pseudocyclopidae may be caused by the use of inadequate sampling methods, indicating the use of demersal-focused samplers, such as emergence traps as an alternative to the sampling of these bottom-dwelling copepods.

In the early 20th century, Orissa, a province in British India, was marked by dismemberment and fragmentation. Nationalist leaders in colonial Orissa often portrayed the province as a disfigured mother to evoke nationalist sentiment among the Odia people and garner support for the unification of the Oriya-speaking tracts in adjacent provinces to form a separate and complete Orissa province. One painting from the period depicts a woman representing “Mother Orissa” being dissected on a table by an Englishman and surrounded by wolf-headed figures representing Bengal, Madras, and Bihar, who were opposed to the idea of Orissa’s unification. However, these leaders were careful not to create an environment of coercion and sought to allow for expressions of difference to foster a healthy national life. One way they did this was by trying to unite intrareligious groups in Orissa while also calling for the need to bring together people of different regions living in Orissa. Additionally, they balanced their allegiance and devotion among three mothers: Mother Orissa, Mother India, and Mother Victoria.

The coexistence of aortic valve atresia and interrupted aortic arch are an extremely rare condition. In this pathology, blood flow to the ascending aorta and coronary arteries should be provided through the ductus arteriosus or collaterals originating from the descending aorta. In rare cases where bilateral ductus arteriosus is present, they can provide circulation. Here, we report two cases in which coronary arteries and ascending aorta were supplied by one ductus arteriosus and distal systemic circulation is supplied by a second ductus arteriosus in one patient and a collateral artery in the other. Initial palliation was successfully performed by bilateral pulmonary artery banding and transcatheter ductal stent implantation in both cases.

The intricacies of modern compensation procedures that value human life, injury, and property are often overlooked, despite growing demands for reparations and justice following state violence. This article historicizes the legal structures of modern compensation, arguing that the advent of imperial rule was characterized not only by the extraction of material resources and labour, but also by the discriminatory construction and implementation of imperial law, which sought to protect European life, wealth, and property. By focusing on one of the most notorious episodes of violence in British imperial and modern South Asian history – the atrocities committed by British officials in Punjab (1919), including the Jallianwalla Bagh massacre – this article underscores how British officials penalized protests and freedom struggles by legalizing indemnities, taxes, and fines to compensate European families. In contrast, colonial officials grossly undervalued the claims and payments of Indian subjects killed or maimed during state violence, if they did at all. Furthermore, this article reveals how imperial state compensation, managed in relative privacy and buried in legal proceduralism, was rooted in legal structures of intersectional racialized inequality, and political concerns that valued the longevity of imperialism, rather than a meaningful gesture of justice and redress.

We measure crypto and financial literacy using microdata from the Bank of Canada’s Bitcoin Omnibus Survey. Our crypto literacy measure is based on three questions covering basic aspects of Bitcoin. The financial literacy measure we use is based on three questions covering basic aspects of conventional finance (the “Big Three”). We find that a significant share of Canadian Bitcoin owners have low crypto knowledge and low financial literacy. We also find gender differences in crypto literacy among Bitcoin owners, with female owners scoring lower in Bitcoin knowledge than male owners. We do not, however, find significant gender differences in financial literacy amongst Bitcoin owners. In contrast, non-owners show gender differences in both crypto and financial literacy.

Here we describe a new species of the genus Saccocoelioides found parasitizing Astyanax dissimilis Garavello & Sampaio, Psalidodon bifasciatus (Garavello and Sampaio) and Bryconamericus ikaa Casciotta, Almirón & Azpelicueta from the Iguazu National Park, Misiones province, Argentina. Saccocoelioides miguelmontesi n. sp. was studied based on morphological and molecular (28S rDNA and COI mtDNA sequences) data. The COI mtDNA tree indicated that the specimens collected from the three fish hosts are conspecific, with an intragroup p-distance of 0%. The new species shows an intermediate morphological configuration between the diminutive and robust forms described for Saccocoelioides by Curran (2018). Although, in the 28S rDNA tree, it is placed in a well-supported clade with the two robust species analysed (S. elongatus and S. magnus; p-distance of 1 and 2%, respectively), it differs from the robust group by the range of body size, mature egg size, oral and ventral sucker size, sucker ratio, oral sucker to pharynx ratio, and post-cecal or post-testis/body length percentage. Our results led us to redefine the robust group as having eggs shorter or equal in length to the pharynx. Saccocoelioides miguelmontesi n. sp. the 10th species reported from Argentina and the 7th species within the robust group.

Alasdair MacIntyre’s critique of managerial capitalism is well known, with some arguing that MacIntyrean thought is antithetical to contemporary capitalist business. Nevertheless, substantial efforts have been taken to demonstrate how different business activities constitute MacIntyrean practices, which points to an incoherence at the heart of MacIntyrean business ethics scholarship. This article proposes a way of bridging these perspectives, suggesting a reimagined MacIntyrean approach to business that is thoroughly ‘practice-led.’ A detailed comparison of accounting and management shows that while neither are practices in ‘good order,’ they differ in significant ways: where management does not meet the criteria for a MacIntyrean practice, accounting is a ‘distorted’ practice. This leads to a categorisation of practice-led business activity, whereby the traditional tasks of management are subsumed, shared or subordinated to practices and practitioners. Insights on how this can be implemented are drawn from the ‘communities of practice’ literature and a consideration of professions.

Neuroscience research underscores the critical impact of adverse experiences on brain development. Yet, there is limited understanding of the specific pathways linking adverse experiences to accelerated or delayed brain development and their ultimate contributions to psychopathology. Here, we present new longitudinal data demonstrating that neurocognitive functioning during adolescence, as affected by adverse experiences, predicts psychopathology during young adulthood. The sample included 167 participants (52% male) assessed in adolescence and young adulthood. Adverse experiences were measured by early maltreatment experiences and low family socioeconomic status. Cognitive control was assessed by neural activation and behavioral performance during the Multi-Source Interference Task. Psychopathology was measured by self-reported internalizing and externalizing symptomatology. Results indicated that higher maltreatment predicted heightened frontoparietal activation during cognitive control, indicating delayed neurodevelopment, which, in turn predicted higher internalizing and externalizing symptomatology. Furthermore, higher maltreatment predicted a steeper decline in frontoparietal activation across adolescence, indicating neural plasticity in cognitive control-related brain development, which was associated with lower internalizing symptomatology. Our results elucidate the crucial role of neurocognitive development in the processes linking adverse experiences and psychopathology. Implications of the findings and directions for future research on the effects of adverse experiences on brain development are discussed.

The term moderate deviations is often used in the literature to mean a class of large deviation principles that, in some sense, fills the gap between a convergence in probability of some random variables to a constant, and a weak convergence to a centered Gaussian distribution (when such random variables are properly centered and rescaled). We talk about noncentral moderate deviations when the weak convergence is towards a non-Gaussian distribution. In this paper we prove a noncentral moderate deviation result for the bivariate sequence of sums and maxima of independent and identically distributed random variables bounded from above. We also prove a result where the random variables are not bounded from above, and the maxima are suitably normalized. Finally, we prove a moderate deviation result for sums of partial minima of independent and identically distributed exponential random variables.

Physics-informed neural networks (PINNs), which are a recent development and incorporate physics-based knowledge into neural networks (NNs) in the form of constraints (e.g., displacement and force boundary conditions, and governing equations) or loss function, offer promise for generating digital twins of physical systems and processes. Although recent advances in PINNs have begun to address the challenges of structural health monitoring, significant issues remain unresolved, particularly in modeling the governing physics through partial differential equations (PDEs) under temporally variable loading. This paper investigates potential solutions to these challenges. Specifically, the paper will examine the performance of PINNs enforcing boundary conditions and utilizing sensor data from a limited number of locations within it, demonstrated through three case studies. Case Study 1 assumes a constant uniformly distributed load (UDL) and analyzes several setups of PINNs for four distinct simulated measurement cases obtained from a finite element model. In Case Study 2, the UDL is included as an input variable for the NNs. Results from these two case studies show that the modeling of the structure’s boundary conditions enables the PINNs to approximate the behavior of the structure without requiring satisfaction of the PDEs across the whole domain of the plate. In Case Study (3), we explore the efficacy of PINNs in a setting resembling real-world conditions, wherein the simulated measurment data incorporate deviations from idealized boundary conditions and contain measurement noise. Results illustrate that PINNs can effectively capture the overall physics of the system while managing deviations from idealized assumptions and data noise.

This study presents the first extensive radiocarbon dating programme of Bronze Age material from northern Germany, and it combines radiocarbon dates, relative typo-chronological date ranges, and stratigraphic data within a Bayesian chronological framework. We estimate the cemetery complex at Mang de Bargen (Bornhöved, distr. Segeberg, Schleswig-Holstein) to be in use for more than two millennia, which is exceptionally long in northern Germany and in a wider European context. The site provides a unique insight into the dynamic nature of burial monuments and associated burial practices, from the Late Neolithic and into the Pre-Roman Iron Age (c. 2500–50 bc). The barrow building tradition lasted around a millennium (c. 2350 –1300 bc), with several barrows in concurrent use. The barrows were persistently re-used as burial ground, both within ‘living memory’ of the primary graves, but also long after. The burial intensity varied over the cemetery’s use-life, with distinct peaks in the Late Neolithic, when the first barrows were erected; in the Older Bronze Age when more barrows were erected; in the Younger Bronze Age, when secondary cremation graves were added to existing barrows; and finally in the Pre-Roman Iron Age, with the addition of an urnfield. The funerary rituals vary considerably over the period: from inhumation to cremation, and from primary and secondary graves in barrows to flat graves. Cremation was introduced in the 14th century bc but inhumation and cremation were used in parallel for around a century before the former ritual was abandoned c. 1300 bc. The study provides absolute chronological distributions of the grave types present at Mang de Bargen and shows them to be comparable to other sites at a regional and over-regional scale, successfully demonstrating how new types were quickly adopted across large parts of north-western Europe.

Recent scholarship has examined Alexis de Tocqueville's underexplored assertion that American racial stratification functioned as an extension of European feudalism. However, Tocqueville was not alone in his insights. At least a half-dozen nineteenth-century African American writers and thinkers, including Frederick Douglass, Frances Ellen Watkins Harper, Maria Stewart, Harriet Jacobs, Sojourner Truth, and especially Hosea Easton, have also described America's racial hierarchy as a continuation of antecedent European feudal social structures. Not only do their perspectives on what I call racial feudalism in America lend credence to Tocqueville's hypothesis that the afterlife of medieval social frameworks continued to persist in the post-Enlightenment United States, but also black Americans establish a distinctive body of knowledge that must be read alongside Tocqueville to render a more complete understanding of antebellum US social hierarchy.

The advent of smart and digital cities is bringing data to the forefront as a critical resource for addressing the multifaceted transitions faced by African cities from rapid urbanization to the climate crisis. However, this commentary highlights the formidable considerations that must be addressed to realize the potential of data-driven urban planning and management. We argue that data should be viewed as a tool, not a panacea, drawing from our experience in modeling and mapping the accessibility of transport systems in Accra and Kumasi, Ghana. We identify five key considerations, including data choice, imperfections, resource intensity, validation, and data market dynamics, and propose three actionable points for progress: local data sharing, centralized repositories, and capacity-building. While our focus is on Kumasi and Accra, the considerations discussed are relevant to cities across the African continent.
