Upper Middle Devonian to lowermost Upper Devonian brachiopods from Mount Józefka near Górno (Holy Cross Mountains, Poland) are described from the Laskowa Góra Beds (mostly top-Givetian dengleri Conodont Biozone) and Szydłówek Beds (Givetian–Frasnian transition). Twenty species are present, whereof two new ones. Glosshypothyridina theophili new species is larger and has a less angular hinge margin than G. procuboides (Kayser, 1871). Data on internal features of Hypothyridina Buckman, 1906, Glosshypothyridina Rzhonsnitskaya, 1978, and Tullhypothyridina Sartenaer, 2003 are summarized on the basis of published and unpublished sources, allowing rectification of previous incorrect interpretations of these genera. Kyrtatrypa stanislai new species resembles middle Givetian K. pauli Halamski and Baliński in Halamski et al., 2024, but possesses rudimentary dental nuclei. Similar (previously unnoticed) minute dental nuclei occur in the type species K. culminigera (Struve, 1966), so the diagnosis of Kyrtatrypa Struve, 1966 is emended. The moderately diverse fauna thrived in biogenic and muddy niches within and around perireefal coral thickets in the protected ramp-slope of the northern Kielce carbonate platform. The at-most modest replacement of brachiopod faunas between the middle Givetian and the early Frasnian times during the post-Taghanic ecosystem recovery is confirmed for the Euramerican shelf. However, a different response to global stresses is evident for the sessile benthos across the Middle–Upper Devonian boundary in the intrashelf basin and the stromatoporoid-coral bank settings. Off-reef communities were more resilient, affected by extinction probably half as much as the more sensitive reef-related faunas. The ecological-evolutionary stasis among bottom-level shelly benthos contrasts with the extinction of the Hamilton/upper Tully fauna in the Appalachian Basin, the type area of the Taghanic Crisis.
This study investigates the response of a Mach 4 flow over blunted plates to free stream disturbances using the linearised Navier–Stokes equations. Six nose radii, ranging from 0.1 to 2 mm, are considered. The free stream conditions match those of the experiments by Lysenko (J. Appl. Mech. Tech. Phys. vol. 31, 1990, pp. 868–873), in which the critical nose radius for transition reversal was found to be approximately 0.5 mm. The current study finds that increasing the nose radius strengthens low-frequency streamwise streaks while stabilising the oblique first mode. This leads to a shift in the dominant instability inside the boundary layer from the oblique first mode to streamwise streaks. For slow acoustic waves, the changeover nose radius is 0.7 mm. For entropy waves, vorticity waves and optimal free stream forcing obtained from resolvent analysis, the changeover nose radius is 0.2 mm. The results reproduce the transition reversal observed in the experiments and suggest that it can occur regardless of the type of free stream disturbances. The streak enhancement is attributed to the increasing magnitude of velocity perturbations near the stagnation line as the nose radius increases. Streamwise vortex-like disturbances of inviscid nature at the stagnation line generate streamwise streaks downstream via the lift-up mechanism. For the most amplified streaks, the ratio of the local boundary-layer thickness to the spanwise wavelength approaches a constant value downstream. This ratio is found to be independent of the nose radius and the type of free stream forcing. For slow acoustic disturbances, the streak strength is found to be insensitive to the angle of incidence.
To evaluate the mental health of play-age children affected by the 2023 Türkiye–Syria earthquakes and their mothers, using single-item scales.
Methods
Four hundred earthquake survivor mother–child dyads were included. The mental health of mothers and children was assessed using single-item screening tools, the Self-Reported Mother Mental Health (SRMH) and the Mother-Reported Child Mental Health (MRCMH).
Results
The prevalence of negative mental health increased from 10% to 52% in play-age children and from 13% to 70% in their mothers after the earthquakes. For post-earthquake negative SRMH, associated factors included limited access to safe water (AOR = 2.52, 95% CI: 1.10–5.75, P = 0.029), good perception of security services (AOR = 0.30, 95% CI: 0.12–0.73, P = 0.008), and post-earthquake negative MRCMH (AOR = 8.65, 95% CI: 4.70–15.91, P < 0.001). For post-earthquake negative MRCMH, associated factors were out-of-house sheltering (AOR = 3.13, 95% CI: 1.72–5.69, P < 0.001), good perception of nutritional services (AOR = 0.46, 95% CI: 0.22–0.96, P = 0.039), pre-earthquake negative MRCMH (AOR = 4.68, 95% CI: 1.87–11.73, P = 0.001), and post-earthquake negative SRMH (AOR = 11.35, 95% CI: 5.92–21.76, P < 0.001).
Conclusion
Post-earthquake mental health outcomes were most consistently predicted by limited basic resources (water and nutrition services), not good service quality, and pre-existing or co-occurring negative mental health.
Journal editors play a central role in academic publishing. However, little is known about the experiences of editors within paediatric cardiology. This study aimed to explore the motivations, workload, peer review challenges, and sustainability of editorial roles in this specialty.
Methods:
A cross-sectional, anonymous survey was conducted among paediatric cardiology journal editors and associate editors. Quantitative responses were analysed descriptively, and free-text responses underwent inductive thematic analysis.
Results:
A total of 28 editors participated. Most respondents (82.1%) identified education and mentorship as key motivations for editorial work. However, 78.6% reported that editorial roles are becoming increasingly difficult, and only 21.4% reported having sufficient protected time, highlighting substantial workload pressures. Reviewer fatigue was a major challenge, with 75.0% reporting difficulty securing timely, high-quality peer review. While 57.9% acknowledged that impact factor influences editorial considerations, 89.5% agreed that journals with lower impact factors remain highly valuable for education. Only 28.6% of respondents considered the current editorial model sustainable, with 46.4% expressing concern regarding long-term sustainability.
Conclusions:
Paediatric cardiology journal editors demonstrate strong intrinsic motivation but face increasing workload, reviewer fatigue, and limited institutional support. These findings highlight a growing imbalance between editorial expectations and available support structures. Greater institutional recognition, provision of protected time, and pragmatic innovation in peer review processes may be required to sustain editorial engagement and maintain the educational and scientific mission of paediatric cardiology publishing.
This paper examines how disparities in market-based and non-market-based environmental policy instruments affect gross exports and domestic value added in exports, distinguishing between intermediate and final goods and services at the industry level. We estimate a theory-based gravity model with country-industry-time fixed effects using Poisson Pseudo Maximum Likelihood for 32 countries, 56 industries and the period 2000–2014. The results show that the widening gap in market-based instruments between countries is associated with competitiveness losses for high-polluting industries – especially producers of intermediate goods – while low-polluting industries experience short-run gains in comparative advantage, with effects concentrated in the manufacturing sector and driven largely by OECD–non-OECD trade. By contrast, the effects of non-market-based regulatory gaps depend on the time period and the institutional quality of the destination country and are associated, in some cases, with export growth in low-polluting industries and with industrial technology upgrading.
A gas flow in a two-dimensional square cavity driven by a lid moving parallel to itself in the cavity plane is considered. The Stokes equations under the no-slip condition predict an infinite series of corner vortices near the lower corners, flow velocity with direction-dependent limiting values at the upper corners, and stress and pressure that diverge inversely with the distance from the upper corners. We examine how these properties are modified or retained within the kinetic theory of gases. The steady behaviour of the gas is numerically investigated based on the linearised Bhatnagar–Gross–Krook kinetic equation and the diffuse reflection boundary condition. No corner vortices are observed for $k \ge 0.03$, where $k = (\sqrt {\pi }/2)\textit{Kn}$ with $\textit{Kn}$ being the Knudsen number. A first corner vortex is observed at $k = 0.02$ and for smaller $k$ examined. A second one is observed at $k = 0.001$ and for smaller $k$ examined. Numerical results imply that their number is finite for each Knudsen number. Macroscopic quantities, including the flow velocity, exhibit direction-dependent limiting values also within kinetic theory. For moderate to large Knudsen numbers, such direction dependence manifests itself even at the lower corners. The stress and pressure vary inversely with the distance from the upper corners up to a few tens of mean free paths. Their increase is suppressed at positions closer to the corners and they remain bounded. Consequently, the total forces acting on the lid and side cavity walls are also finite, and they exhibit an unconventional scaling $\textit{Kn} \ln \textit{Kn}$ for small $\textit{Kn}$.
The presence of the vilica or female supervisor at a Roman villa is attested across five centuries in varied texts, and her duties are detailed in an entire book of Columella’s On Agriculture. This paper challenges assumptions by modern scholars that her managerial functions were confined to those of a housekeeper, focused on food supplies for the household and the supervision of domestic labor inside the house. Through closer examination of textual, iconographic, and archaeological evidence, we can see that the vilica’s principal role was to oversee not the domestic sphere, but rather a range of vital productive activities on the farm. In particular, she seems to have been responsible for wine and oil making and for important rituals linked to production. This has implications for our understanding of the roles of women within Roman farming and the Roman economy.
This article examines the renewal of Spain's corporate elite between 1920 and 2020 by combining Social Network Analysis with prosopography. Using interlocking directorate data for the two hundred largest Spanish firms, aggregated into three periods (1920–1950, 1960–1980, and 1990–2020), the study identifies the most structurally central directors and reconstructs their social origins, education, and career trajectories. The findings reveal that while the structural core of corporate power remained remarkably stable—between thirty-four and forty individuals per period, less than 1 percent of all directors—its social composition changed substantially. Aristocratic backgrounds and dynastic ties gave way to middle-class origins, public university credentials, and senior civil service careers. Two institutional channels drove this transformation: the state, whose role shifted from direct political overlap to technocratic circulation through public administration; and the public university system, which increasingly replaced inherited status as the basis of elite recruitment. Rather than democratization, renewal took the form of controlled circulation: new actors entered through selective pathways while the underlying power structure remained intact. By adopting an interpersonal perspective over a full century, the article addresses a persistent gap in the literature on interlocking directorates, which has focused mainly on firm-centered networks rather than their most central actors.
In her work on the interconnected systems of mass incarceration and child welfare, Dorothy Roberts points out a pattern of institutionalized harm that strikes not at the atomic individual, but at the connections between individuals. Similarly, Ross and Solinger draw attention to ways that the state devalues and destroys family bonds within marginalized communities as a central example of reproductive injustice. In this text, I’ll argue that in order to understand this pattern of injustice we need a framework that exceeds the logic of individual rights and harms, and allows us to highlight harms that target the connections between people. I call this kinship violence; here, I explore the distinct characteristics of this form of violence and argue that it is a key aspect of racial and colonial oppression. In response to this violence, Ross and Solinger argue for a right to parent; I elaborate on this idea, considering possible limits or misappropriations by right-wing fathers’ rights and parental rights groups, the risks of protecting abusive or neglectful parents, and the limitations of a rights framework for opposing kinship violence. I argue that a carefully articulated feminist right to parent is a useful but incomplete framework, and suggest that such a right should be seen as part of a larger field of “kinship justice.”
It is widely understood that business is powerful in American politics, and a prominent view among political scientists is that business influence pushes policy to the right, in favor of smaller government. As vast as the literature on business power is, however, it has so far neglected an important part of American government: its tens of thousands of local governments. Moreover, although there has been a surge in US local politics research in recent years, it has not yet examined businesses’ positions on local government policies. This essay begins to bridge these gaps. I propose that businesses and business associations may often support well-funded local government, in alignment with unions, because of the kinds of policies local governments make and their relatively smaller scale. In an analysis of campaign contributions to local tax ballot measures in California, I find that the overwhelming majority of union and business contributions are made in support of tax increases. In another analysis of local chambers of commerce positions on local tax and bond ballot measures, I find that chambers endorsed passage for 70% of them. These findings underscore the need for more research on a host of important questions about American politics, comparative politics, and business preferences.
Enhanced recovery after surgery has an established evidence base in paediatric cardiac surgery, but formal programmes are infrequently implemented in Europe. Before implementing a programme, it is essential to assess current performance for benchmarking and to identify potential pitfalls.
Methods:
A retrospective single-centre cohort study was performed to assess the peri-operative course of a low-risk group of children undergoing congenital cardiac surgery. Patient data were collected for the entire post-operative course before discharge home or to a different centre. Data regarding respiratory and haemodynamic support, invasive devices, length of stay, and analgesia were extracted from electronic intensive care records and paper ward records.
Results:
The search criteria yielded 1042 operations. Following a detailed assessment of inclusion and exclusion criteria, 73 patients were included in the study. Included patients had a median age of 3.1 years and a median weight of 13 kg. Seventy-one per cent (52/73) of patients underwent early extubation within six hours. Some children without contraindications did not receive non-opioid analgesia. Most invasive devices (pacing wires, drains, and central venous catheters) were removed on the ward. The median length of stay was 1.1 days in critical care and 4.3 in hospital.
Conclusions:
Early extubation and duration of stay were comparable to outcomes published by some established enhanced recovery after surgery programmes, although shorter stays are achievable. Areas for improvement were identified. A centre’s specific context must be considered when implementing aspects of an enhanced recovery after surgery programme.
In the Supreme Court’s 5-4 decision in Milliken v. Bradley (1974), its majority held that “no single tradition in public education is more deeply rooted than local control.” The court’s opinion overturned US District Court judge Stephen Roth’s order for metropolitan desegregation to remedy segregation in Detroit. Histories of the Milliken decision have often narrated its meaning and consequence through metropolitan histories of segregation, but the legal issue at the heart of Judge Roth’s holding and the court’s decision to overturn it concerned the state’s educational authority and whether state constitutional violations enabled more expansive remedies. This article retraces the policy and legal history of state power in producing segregation and inequality before and after the Milliken decision. It illustrates how the Supreme Court’s reasoning produced a political situation in which State policymakers could uphold segregation and inequality without consequence when isolating Detroit’s schools for intervention.
This article addresses the challenges in formulating data-sharing regulations by proposing a systematic regulatory matrix based on data characteristics. While data-driven innovation drives economic growth, existing legal frameworks in the EU are incoherent and often tend towards data propertisation, even if indirectly, which may lead to data underutilisation. The matrix is built on varied data characteristics, and it aims to foster access to data and data sharing as a fundamental general principle underpinning the data-driven innovation market. This framework offers a balanced regulatory scheme ranging from open access to proprietary models, aiming to maximise innovation and public good in the emerging field of data law.
Agrifood systems (AFSs) generate environmental, social and health costs unaccounted for in market prices. True cost accounting makes hidden costs explicit, providing evidence for enhanced sustainability, equity and resilience. Combining project sites’ micro-level and national-level data, we assess externalities in Kenya and Viet Nam. At the national level, we find that externalities constitute one-third of AFS output value in Kenya, with social costs accounting for three-quarters of this total. In Viet Nam, externalities represent one-sixth of output, driven by environmental costs, constituting three-quarters of externalities. In project sites, external costs (excluding health) account for 30 per cent of production costs in Kenya, mostly driven by social costs (84 per cent). External costs represent 24 per cent of production costs in Viet Nam, among which environmental costs (61 per cent) dominate. Strategies to reduce costs include stronger labour regulations, investments in resource-efficient technologies and prudent input management. Priority interventions include empowering workers, strengthening farmer performance and addressing gender-based labour disparities.
