This paper uses a new linked sample constructed from full-count census data of 1851–1911 to revise estimates of intergenerational occupational mobility in England. I find that conventional estimates of intergenerational elasticities are attenuated by classical measurement error and severely underestimate the extent of father-son association in socioeconomic status. Instrumenting one measure of the father’s outcome with a second measure of the father’s outcome raises the intergenerational elasticities (β) of occupational status from 0.4 to 0.6–0.7. Victorian England was therefore a society of limited social mobility. The long-run evolution and international comparisons of social mobility in England are discussed.
Research points to the substantial impact of parents' exposure to adverse childhood experiences (ACEs) on parents and their children. However, most studies have been conducted in North America, and research on ACEs effects on observed parenting or on intergenerational transmission of ACE effects is limited. We therefore studied families from diverse ethnocultural backgrounds in Israel and examined whether mothers’ ACEs hampered maternal sensitivity and the quality of the home environment and whether mothers’ psychological distress mediated these links. We also explored whether mothers’ ACEs predicted children’s behavior problems indirectly through maternal psychological distress and whether maternal sensitivity and the home environment attenuated this mediating path. Participants were 232 mothers (Mchild age = 18.40 months, SD = 1.76; 63.36% non-ultra-Orthodox Jewish, 17.24% ultra-Orthodox Jewish, 19.40% Arab Muslim). Results showed mothers’ ACEs were directly associated with decreased maternal sensitivity. Mothers’ ACEs were indirectly associated with more behavior problems in children through mothers’ higher psychological distress, and maternal sensitivity moderated this indirect link; it was significant only for mothers who showed lower sensitivity. Findings emphasize the significant role ACEs play in early mother-child relationships. The importance of including ACE assessment in research and practice with families of infants and toddlers is discussed.
This article presents some preliminary results of the first field season of 3D documentation of buildings, monuments, and portable artifacts from the archaeological site of Dzibanche in Quintana Roo, Mexico. Documentation took place at Dzibanche, in the INAH regional research center in Chetumal, and in the Maya Museum of Cancun. Part of the resultant corpus of imagery and inscriptions has not been previously disseminated in academic literature. The analysis of published texts and iconography has benefited from higher resolution and visualization tools made possible by 3D digitization. The presentation proposes several updates to the published interpretations of Dzibanche monuments, and it highlights how new additions to the corpus expand our understanding of Dzibanche's political history and ideology.
Microcephalic osteodysplastic primordial dwarfism (MOPD) syndrome type 2, caused by a mutation in the PCNT gene (21q22.3), is a rare autosomal recessive disorder. Patients present with bone dysplasia, insulin resistance, kidney diseases, and cardiac malformations, making them prone to vascular diseases. Cardiomyopathy, hypertension, and coronary diseases are documented. The prognosis is associated with cerebrovascular complications.
Method:
We report a case of a patient with MOPD type II who suffered a myocardial infarction in our institution. Informed consent for publishing was obtained.
Result:
A 17-year-old female with MPOD II syndrome (20 kg and 86 cm) was referred for chest pain. Thoracic pains had been occurring for over a month, increasing in intensity, with an episode prompting emergency consultation. Initial tests revealed elevated troponin and an inflammatory response. Electrocardiogram (ECG) showed ST-segment depression and elevation. Echocardiography revealed hypokinetic inferior walls with moderate concentric hypertrophy. A coronary CT scan showed subendocardial hypodensity. Diagnostic coronary angiography revealed tri-branch lesions and almost complete stenoses or occlusions on the circumflex artery (Image). No indication for interventional treatment due to diffuse atheromatous lesions. Exclusive medical treatment was initiated.
Conclusion:
MPOD II syndrome is associated with cardiac malformations and neurovascular complications, including myocardial infarction. Regular ECG monitoring is advisable. Active surveillance for coronary diseases is necessary from adolescence. Recognising this complication allows for prompt intervention. This case highlights the need for specific monitoring and prompt management of chest pain in patients with MPOD II syndrome. Primary prevention could mitigate the occurrence of coronary events in this high-risk population.
From the seventeenth to the twentieth century, rivers played a key role in the colonization of Hokkaido, a northern island in the Japanese archipelago. The Kushiro River, in eastern Hokkaido, was transformed into infrastructure, a process which shaped the institutions, strategies, and practices of territorial control during the transition from the Tokugawa shogunate (1603–1868) to Imperial Japan (1868–1947). Trade between local Ainu communities and the shogunate's vassals contributed to a river-based territoriality. Later in the 1800s, as the island became territory of the modern state, the river was further converted into infrastructure through settler colonialism, industrial development, land reclamation, and the dispossession of indigenous communities. This transformation empowered the state to probe territories, exert control over labor, and access natural resources. Drawing on research on the political ecology of rivers, this paper focuses on two hydrosocial functions that emerged during the process of reworking river basins into legible and governable spaces: the transportation conduit and the water delivery system. The river's transition from a living system to infrastructure coincided with and furthered the establishment of colonial settlements and the expansion of the Japanese state's imperial reach.
The volume filtering of the governing equations of a particle-laden flow allows for simulating the fluid phase as a continuum, and accounting for the momentum exchange between the fluid and the particles by adding a source term in the fluid momentum equations. The volume filtering of the Navier–Stokes equations allows consideration of the effect that particles have on the fluid without further assumptions, but closures arise of which the implications are not fully understood. It is common to either neglect these closures or model them using assumptions of which the implications are unclear. In the present paper, we carefully study every closure in the volume-filtered fluid momentum equation and investigate their impact on the momentum and energy transfer dependent on the filtering characteristics. We provide an analytical expression for the viscous closure that arises because the filter and spatial derivative in the viscous term do not commute. An analytical expression for the regularization of the particle momentum source of a single sphere in the Stokes regime is derived. Furthermore, we propose a model for the subfilter stress tensor, which originates from filtering the advective term. The model for the subfilter stress tensor is shown to agree well with the subfilter stress tensor for small filter widths relative to the size of the particle. We show that, in contrast to common practice, the subfilter stress tensor requires modelling and should not be neglected. For filter widths comparable to the particle size, we find that the commonly applied Gaussian regularization of the particle momentum source is a poor approximation of the spatial distribution of the particle momentum source, but for larger filter widths, the spatial distribution approaches a Gaussian. Furthermore, we propose a modified advective term in the volume-filtered momentum equation that consistently circumvents the common stability issues observed at locally small fluid volume fractions. Finally, we propose a generally applicable form of the volume-filtered momentum equation and its closures based on clear and well-founded assumptions. Based on the new findings, guidelines for point-particle simulations and the filter width with respect to the particle size and fluid mesh spacing are proposed.
The article presents the results of the last decade of archaeological and epigraphic research, which clarified the history of the polities of the ancient Maya sites of Holmul and Naranjo during the expansion of the Dzibanche royal dynasty in the eastern area of the Department of Peten, Guatemala, from the second half of the sixth century through the first half of the seventh century a.d. The discussion centers on the textual and material indicators of the geopolitical contacts of the royal families of Sak Chuwen of Naranjo and Chak Tok Wayaab of Holmul, including changes in polychrome pottery and hieroglyphic inscriptions, in particular, rhetoric of good governance and political loyalty. In the case of Holmul, the transformation affects the urban landscape of the site. New data clarify the relationship between Holmul and Naranjo during the initial period of their subordination to the kings of Dzibanche. The emerging picture of these secondary alliances and hierarchies within the Kaanu'l domain is essential for a better understanding of Classic Maya political systems at local and regional levels.
En la Mesa Redonda de Palenque de 2004 Erik Velásquez propuso que los gobernantes mayas que portaban el glifo emblema de Kaanuˀl pudieron haber residido durante el Clásico Temprano en Dzibanché, pues no existen referencias que los vinculen con Calakmul antes de 631 d.C. Aquí revisamos los datos sobre su presencia en Dzibanché y otros asentamientos de la región. Argumentos de distinta naturaleza que apoyan este escenario se publicaron desde 2005 hasta 2016, incluyendo los hallazgos de Xunantunich (Helmke y Awe 2016a, 2016b), que permiten conjeturar que una facción disidente de la dinastía se separó de Dzibanché y fundó en 635 d.C. una sede alternativa en Calakmul. Ello produjo el panorama que proponemos en el Clásico Tardío, donde había mandatarios simultáneos de la dinastía Kaanuˀl en el sur de Campeche y en el sur de Quintana Roo, toda vez que en Dzibanché seguían residiendo gobernantes Kaanuˀl al menos hasta el siglo VII.
Inference in spatial and spatio-temporal models can be challenging for a variety of reasons. For example, non-Gaussianity often leads to analytically intractable integrals; we may be in a ‘big’ data setting, whereby the number of observations renders traditional methods too computationally expensive; we may wish to make inferences over spatial supports that are different to those of our measurements; or, we may wish to use a statistical model whose likelihood function is either unavailable or computationally intractable. In this thesis, I develop several techniques that help to alleviate these challenges.
Previous studies investigating behavioural health screening processes have focused on selected diagnoses within paediatric cardiology and focused on a smaller number of potential concerns. We developed and administered a brief survey in our paediatric heart centre to assess the presence of a wider variety of behavioural health concerns and to connect patients with resources. A cohort of 305 patients aged 2–29 years (M = 11.97 years; SD = 6.00 years; 50.49% female), representing a variety of indications for a cardiology clinic visit, or a parent, completed a survey of 14 common behavioural health concerns. Behavioural health concerns were included based on practice patterns within paediatric psychology. Respondents indicated if they were currently receiving behavioural health services and if they were interested in behavioural health follow-up. Surveys were administered during check in and collected by clinic staff. A behavioural health provider attempted to reach all those who indicated interest by phone. Approximately 45% of the sample endorsed one or more behavioural health concerns and 30.16% of the sample endorsed at least one concern but were not already connected to services. Only 27.17% of this group requested follow-up. Most commonly endorsed concerns were anxiety, sleep problems, depressed/irritable mood, and somatic complaints. Survey results converge with existing literature to indicate that behavioural health concerns are common among youth seen in a paediatric cardiology clinic but most patients are not connected to appropriate services. Screening programmes can help meet this need but challenges remain. Clinical implications and future directions are discussed.
Hereditary connective tissue diseases have different risks of aortic dissection depending on the causative gene. We report a family with no extravascular phenotype and a clinical diagnosis of familial thoracic aortic aneurysm and dissection, but genetic testing confirmed p.Tyr470Cys in TGFBR2, which is typically the responsible gene for Loeys–Dietz syndrome. Validation of the clinical diagnosis by genetic testing is warranted.
‘Biological’ and ‘social’ perspectives in psychiatry have exchanged dominance at different times in the history of our field and are sometimes erroneously viewed as being contrasting and mutually exclusive paradigms. We argue that the arbitrary ‘biological/social’ divide in psychiatry is misleading, unhelpful, and ultimately a false one. We propose that the evolutionary perspective provides a necessary framework and metatheory that can bridge this apparent schism in psychiatric thinking, providing novel and useful insights into how we can better assess, diagnose, and treat our patients.
The Kaanuˀl dynasty ruled a hegemonic state with political influence over much of the Classic Maya Lowlands between a.d. 520 and 751. The present article introduces the subject for a special section of the journal, which refocuses attention on the archaeological zone of Dzibanche in southern Quintana Roo, Mexico, where new data are emerging about the origins of the Kaanuˀl dynasty, its urban organization, and its connections to neighboring centers. In this article, we present new data from a recent lidar survey as well as from previous work by Enrique Nalda's Instituto Nacional de Antropología e Historia (INAH) project to reevaluate Dzibanche's characteristics vis-à-vis its rise as a kingdom with far-reaching political influence. We complement these archaeological data with epigraphic information from new monuments and reanalysis of existing ones based on 3D scanning to update the list of Dzibanche rulers. We then revisit the chronology of Dzibanche's royal burials proposing correlations with known Early Classic Kaanuˀl rulers. Overall, the contributions to this special section present new perspectives on the Kaanuˀl's rise to power and its relationship with distant vassals in the crucial period of expansion into northern Peten, leading to the defeat of Tikal and eventually to its transition to a new dynastic seat at Calakmul in the a.d. 630s.
Medical dramas such as Grey's Anatomy influence young people's career aspirations, creating unrealistic expectations. This article examines the gap between these portrayals and the reality of medical practice, highlighting challenges such as rigorous training and high stress. Using Italy's ‘numero chiuso’ (‘closed number’) system as a case study, it addresses the global issue of intense competition in medical school admissions. The article advocates for realistic education and better support to prepare future healthcare professionals.
