The behavior of parent-incumbents depends not only on their own intention to hand over the family firm but also on their child-successors’ willingness to take over. Drawing on socioemotional wealth (SEW) theory, we develop a model of the impact of perceived child-successors’ willingness on parent-incumbents’ corporate philanthropy prior to succession. We argue that perceived child-successors’ willingness increases parent-incumbents’ transgenerational succession anticipation and the resulting desire to preserve SEW, which in turn motivates them to engage more in corporate philanthropy. However, parent-incumbents facing a greater threat of state expropriation engage less in philanthropy, as they anticipate a lower likelihood of successful transgenerational succession. Using data from a national survey of Chinese family firms, we find support for our hypotheses. Our findings highlight the significance of internal succession anticipation and its interplay with the external institutional environment in shaping family firm philanthropy.

Most psychiatric disorders in adulthood originate in childhood or adolescence. Hence, managing mental health in children and adolescents is crucial. This clinical reflection aims to capture some of the contemporary and emerging trends in teaching and training in child and adolescent psychiatry worldwide. Future directions for child and adolescent psychiatry training programmes are also highlighted.

Theories of bounded rationality join process reliabilists in holding that rationality is ecological, or environment-relative. Most theories of ecological rationality, like most versions of reliabilism, have been externalist. In this paper, I develop a de-externalized account of ecological rationality. I show how the account retains many advantages of externalist accounts while avoiding key challenges. I conclude with an application to the psychology of poverty, focusing on the rationality of agents caught in poverty traps.

This study provides the first integrative analysis of Megacoelium spinicavum Thatcher & Varella, 1981 (Digenea: Haploporidae) from the Amazon sailfin catfish Pterygoplichthys pardalis Castelnau, 1855 (Siluriformes: Loricariidae) in the Peruvian Amazon. A detailed morphological description is presented, including the first scanning electron microscopy (SEM) images of tegumental structures, which revealed two distinct types of tegumental spines: (1) small, button-like spines and (2) sharply pointed spines. Partial sequences of the 28S rDNA and mitochondrial cox1 genes were generated and analysed to investigate the phylogenetic position of Megacoelium Szidat, 1954, within the Haploporidae Nicoll, 1914. Phylogenetic analyses placed M. spinicavum within the ‘robust species’ clade of Saccocoelioides Szidat, 1954, clustering with S. bacilliformis Szidat, 1973, although with weak support. These results provide additional evidence that Saccocoelioides is not monophyletic and support restricting the genus to the ‘minute species’ clade containing the type species. The ‘robust species’ clade appears to comprise at least three divergent lineages, potentially representing distinct genera, one of which includes M. spinicavum. The absence of molecular data for M. plecostomi Szidat, 1954, the type species of Megacoelium, continues to obscure its phylogenetic placement. We highlight the need for comprehensive morphological and multilocus molecular analyses, including SEM, to clarify the taxonomic status of Megacoelium and to resolve the evolutionary relationships of chalcinotrematine digeneans in Neotropical fishes.

This study aimed to compare the pre-defoliation heights of Marandu palisade grass (MPG) grown in full sun conditions versus those grown in a silvopastoral system with varying levels of shading over two years of pasture management. The experimental design adopted was completely randomized, and the treatments were arranged in a split-plot design, with different shading levels implemented between the silvopastoral system rows. The shading treatments included silvopastoral with 55-60%, 50-55%, 45-50%, and 40-45% shading, obtained as a function of the spacing between eucalyptus trees, along with an additional treatment of MPG grown in full sun (monoculture). In the subplots, four pre-defoliation management heights for MPG were tested: 30 cm, 40 cm, 50 cm, and 60 cm. The results revealed that the total number of tillers was higher in the full sun treatment, showing an average of 12.5% more tillers per m2 over the two years compared to the highest shading treatment in the silvopastoral system. Additionally, pre-defoliation heights of 40 cm and 50 cm demonstrated the highest total chlorophyll indices in the MPG plants. The greatest dry mass productivity of MPG was also observed at pre-defoliation heights of 40 cm and 50 cm. Increasing shading levels negatively impacted the productivity of the MPG. However, MPG managed at pre-defoliation heights of 40 cm and 50 cm exhibited better adaptation to the shaded system. This reinforces its suitability for silvopastoral systems due to its good shade tolerance (40–45%) and the flexibility it provides in pasture and livestock management.

Efficient global localization of mobile robots in symmetrical indoor environments remains a formidable challenge, given the inherent complexities arising from uniform structures and a dearth of distinctive features. This review paper conducts an in-depth investigation into the nuances of global localization strategies, focusing on symmetrical environments, such as extended corridors, symmetrical rooms, tunnels, and industrial warehouses. The study comprehensively reviews and categorizes key techniques employed in this context, encompassing probabilistic-based approaches, learning-based approaches, Simultaneous Localization and Mapping (SLAM)-based approaches, and optimization-based approaches. The primary goal is to provide a contemporary and thorough literature review, offering insights into existing global localization solutions, followed by extant methods tailored for symmetrical indoor spaces. Also, the paper addresses practical challenges associated with implementing various global localization techniques, contributing to a holistic understanding of their real-world applicability. Comparative experimental results demonstrate that hybrid approaches achieve superior localization accuracy in symmetrical environments compared to any single method alone. These experiments, conducted in indoor settings with different symmetry levels, highlight the hybrid approach’s robustness and precision in resolving symmetry-induced ambiguities. This work signifies a significant step forward in mobile robot global localization, which addresses symmetrical environments’ complexities by leveraging the strengths of hybrid methodologies.

This paper argues that, while the famous “first shot formula” represents the dominant interpretation for the application of common Article 2(1) of the Geneva Conventions, its application in the case of unilateral use of lethal force for the targeted killing of military personnel in the territory of a third state is not compatible with the requirements of humanity and the object and purpose of these treaties. The paper contends such an operation will not ipso facto trigger an international armed conflict between targeting state and the state of the targeted person. By examining the elements that constitute an international armed conflict, the paper proposes a new criterion for determining the beginning of such a conflict in cases of targeted killing of military personnel in the territory of a third state.

Although battles have usually been analysed to study state formation, they can also be examined to understand socio-cultural processes in the empire. The Battle of Dharmat (26 April 1658), which occurred during the famed Mughal War of Succession (1657–1659) that led to the accession of Aurangzeb Alamgir (r. 1658–1707), was a landmark moment in Rajput history and memory. Rajput clans serving in the Mughal army at Dharmat commissioned vernacular literary-historical works to put forward competing claims to martyrdom, bravery, clan, and caste pride. Particularly, Dharmat provided an opportunity for minor clans to establish their fallen leaders, like Ratan Rathor, as heroes, especially after the prominent Rajput king Jaswant Rathor fled the battlefield. The Rajput retellings of the battle deliberated questions surrounding masculinity, loyalty, sacrifice, and qualities underpinning the ideal martial Rajput identity. The contrasting portrayals of the ‘martyr’ and the ‘deserter’ at Dharmat represented a conflict between personal virtue and failure, capturing the chasm between honour and disgrace in the Rajput socio-political and cultural sphere. By drawing on Dingal poetry, Marwari chronicles, Persian literature, and the accounts of foreign travellers, this article unravels how a Mughal battle became a site for rehearsing normative Rajput caste ideals in seventeenth-century India.

This article presents an analysis of two sheet gold ornaments of the Mycenaean post-palatial period (twelfth–eleventh centuries bc) found in two cemeteries on the island of Kefalonia. These unusual ornaments bear solar symbols of Nordic and central European type, the closest parallels being those on the contemporary gold discs from votive deposits on the Italian peninsula. The study considers the technological, morphological, and iconographic particularities of the Kefalonian ornaments and how they differ from each other and from other finds. The ornaments’ use in a funerary context is examined against Aegean practices, burial rites, and ideology. The examination of their iconographic and conceptual antecedents in the Aegean cultural sphere reveals that the exogenous input in their creation—linked to transcultural exchange within the Adriatic—was matched by indigenous engagement with aspects of cosmology.

This paper invites reflection on the nature and role of visual illustration in economics, through a historical account of the “Hayekian triangle,” a graphical representation devised by Friedrich A. Hayek to depict the structure of production and introduced in his 1931 book Prices and Production. Tracing its origins back to Hayek’s earlier “schemes” in 1929, the paper then examines the triangle’s evolution and its applications in visualizing economic phenomena such as capital accumulation and business cycles. The paper also highlights key developments by contemporaries and successors, such as Evan F. M. Durbin, Murray N. Rothbard, and Roger W. Garrison, as well as more recent formalizations that integrate mathematical precision.

This paper examines the morality of medical assistance in dying (MAID) in Kantian ethics. I argue that it is much harder than is often acknowledged to rule MAID out, even given Kant’s prohibition on suicide. Kant’s non-consequentialism entails that providing MAID does not aid the patient’s duty violation. Moreover, Kant’s distinction between public and private reason provides resources for arguing that those who provide MAID are not complicit with that violation either, at least in jurisdictions in which there is a public mandate. On my reading, the ethical permissibility of providing MAID is largely determined by its legal status.

This article examines the Tangchaodun bema—a liturgical structure dating to the Gaochang Uyghur Kingdom in Xinjiang—as a regional manifestation of the architectural and theological tradition of the Church of the East, shaped over centuries of transmission and adaptation. Through comparative analysis of archaeological remains and liturgical texts from Syria, Mesopotamia, and Central Asia, the study argues that the Tangchaodun bema follows the ‘eastern-type bema’ model rooted in the East Syrian tradition. Its spatial configuration and ritual function reflect established Mesopotamian patterns, particularly in the mirroring of bema and sanctuary, while also incorporating localised features shaped by visual adaptation and intercultural contact. Bilingual inscriptions and iconographic traces further attest to this integration of tradition and regional context.

Rather than existing in isolation, the Tangchaodun bema forms part of a broader historical development in East Syriac ecclesiastical architecture. By positioning the site within this extended line of transmission, the article shows how sacred space operated as a medium of both theological continuity and cultural dialogue across Asia. In so doing, it offers new perspectives on the role of Christian architecture in the Tang to Yuan Dynasties and contributes to a more integrated understanding of the Church of the East in its easternmost reaches.

From the 1960s, the rising volatility of financial markets in the US troubled econometricians and bank managers alike. Both found it increasingly difficult to forecast savings deposit flows. This article explores these challenges by focusing on two developments. First, it analyzes the adjustment process among econometric models of the savings deposit market. I combine the analysis of the FMP model used by the Fed since 1970 and the deposit model of the Philadelphia Saving Fund Society (PSFS), thereby pioneering the historical analysis of econometric models built by private financial institutions. I find that economists failed to discover timeless determinants for deposit flows. Second, I explore how the conditions of the savings deposit market shaped the demand for macroeconomic forecast models, using the PSFS as a case study. I show that while the rising volatility led bank managers to seek sophisticated tools to predict deposit flows, the deregulation of the banking industry put the forecasting quality of macroeconomic models for individual banks to the test.

Hydrogen is a leading candidate for zero-emission propulsion in aviation, particularly when stored and utilised in its liquid form. However, key components such as composite cryogenic pressure vessels remain at low Technology Readiness Levels (TRL), requiring further investigation into their structural performance under realistic operational conditions. The present work aims to provide a validated numerical methodology for simulating the thermomechanical behaviour and the progressive damage evolution of composite cryogenic hydrogen tanks. The finite element framework incorporates ply-level failure criteria and stiffness degradation laws to capture intra-laminar damage mechanisms under combined pressure and temperature loads. The modelling approach is validated against experimental data from coupon-level open-hole tension tests and subcomponent-scale composite pipes burst tests, demonstrating strong correlation in terms of failure onset and progression.

The validated methodology is subsequently applied to a demonstrator, comprising a composite liquid hydrogen tank, subjected to three representative loading scenarios: internal pressure, cryogenic temperature and combined cryogenic-mechanical loading. Results reveal that matrix-dominated damage initiates near the cylinder – dome interfaces of the tank and propagates across the laminate, while fibre failure is not observed in the investigated load cases. This suggests that potential hydrogen leakage is the initial critical failure condition that occurs before any other important structural damage of the tank, highlighting the need for appropriate tank design. The performed study contributes to the understanding of structural integrity of composite cryogenic tanks and offers a computational basis for future design and certification efforts in hydrogen aviation systems.

This research communication aimed to describe the concentrations of major bone metabolic markers in colostrum from dairy cows on the day of calving and to clarify their associations with parity and the incidence of milk fever (MF). Forty-five Holstein cows were categorized into three groups based on parity: P1 (first calving; n = 18), P2 (second calving; n = 11) and P3 (third to sixth calving; n = 16). Within the P3 group, 6 cows developed MF within a few hours after calving (MF cows), whereas 10 showed no signs of MF (non-MF cows). Concentrations of osteoprotegerin (OPG), tartrate-resistant acid phosphatase isoform 5b (TRAP5b), cross-linked N-telopeptide of type I collagen (NTx), bone-specific alkaline phosphatase (BAP or ALP3) and calcium (Ca) were measured. With increasing parity, serum concentrations of Ca, ALP3 and TRAP5b significantly declined (P < 0.001–0.05). Parity also significantly influenced colostral bone markers: colostral BAP was highest in the P2 group (P < 0.01). Among P3 cows, serum Ca concentrations were significantly lower in MF cows than in non-MF cows, although no significant differences were observed in colostral Ca concentrations. Although no statistically significant differences were detected in other colostral bone metabolic markers between MF and non-MF cows, colostral OPG concentrations tended to be higher in MF cows (P = 0.088). Across all 45 cows and within the P3 group, colostral OPG was moderately and positively associated with serum OPG, as well as with both colostral and serum NTx concentrations. In conclusion, colostral OPG concentration in parturient cows with three or more parities may serve as a useful indicator for reflecting the bone metabolic status of dairy cows with and without MF.

The design of a hexagonal six-ridged waveguide (H6RWG) phased array antenna (PAA) element featuring a wide scan angle matched slotted horn aperture is presented for Ka-band satellite downlink in low Earth orbit non-terrestrial network applications. The proposed PAA element is evaluated against an open-ended waveguide (OEWG) PAA element and achieves a very low active reflection coefficient (ARC) of less than -18 dB and a total antenna efficiency greater than 84% over a wide bandwidth from 17.3 to 20.2 GHz with a $\pm$ 50$^\circ$ scan range. Specifically, the aperture of the H6RWG was designed to limit the variations in ARC during scanning, thereby minimizing load pulling of integrated active devices, as demonstrated with a power amplifier (PA) in a co-simulation. As a result, the power-added efficiency, output power, and linearity of the PA remained stable over the bandwidth and scan range. Compared to the OEWG PAA, the co-polarized system efficiency and equivalent isotropic radiated power are improved for most scan angles within the bandwidth, especially at high scan angles.

The Arctic, once a climate victim, is now becoming a climate stressor. The melting ice has brought us closer to climate tipping points and, simultaneously, has made oil reserves in the Arctic more accessible. As a result, a clash has emerged between scientific warnings and climate change obstruction (CCO) discourses that prioritise economic ambitions over climate concerns. This study investigates whether, despite scientific warnings, Norway defends further oil extraction in the Arctic, thus aligning with CCO discourses by prioritising economic interests over climate urgency. Based on a qualitative inductive approach, we analyse four official White Papers from the Norwegian government, identify their discursive patterns and contrast them with CCO discourses found in the literature. We found that the Norwegian government exhibits an affinity with six CCO discourses: 1) Non-Transformative Discourse, 2) Responsibility Deflection Discourse, 3) Discourse of the Common Good, 4) Discourse of Higher Priorities or Loyalties, 5) The Legal Discourse, and 6) The Discourse of Good Intentions. We conclude that the Norwegian government has constructed a narrative where the recognition of climate urgency does not mean the renouncement of its long-term petroleum interests and further oil extraction in the Arctic. This narrative, named here as the “green oil” narrative, uses renewable energies to electrify the oil industry, thus presenting renewables as an ally of oil expansion rather than a step toward a fossil fuel phase-out. Overall, Norway’s current narrative fails to address oil dependency, defending and justifying oil extraction in the Arctic.
