We propose a bio-psycho-socio-anthropological (BPSA) model that mainstreams cultural formulation and power-aware practice across training, interventions and evaluation. Contrasting it with transcultural and community models, we show UK examples where embedding cultural insight in statutory decisions reduced detentions and improved engagement, aligning with national equality priorities.
The thesis of this article is that the understanding of the vocation of an artist in the writings of Jacques Maritain emerges as to develop habitus (practical virtues of the intellect) in order to direct their inspirations in order to make beautiful things that convey the spiritual heritage of the nation and the civilization and inspire others to contemplate God. This vocation to be an associate of God in creating beautiful works is a powerful reminder of the close relationship between all personal vocations and the common good. First I explore Maritain’s conversion to Catholicism, including through the arts. I next clarify Maritain’s Thomistic understanding of art as one expression of the illuminating intellect. I then review Maritain’s writings about the arts in education. I conclude with theological and pastoral reflections on the vocation of an artist.
We characterize dynamics of every distortion element in the group of diffeomorphisms of the 2-sphere that has at least two fixed points and another recurrent point. The key result is that if f is such a diffeomorphism, then the homeomorphism $\check {f}_{\mathrm { ann}}$, which is a lift of the homeomorphism of the closed annulus $\overline {\mathcal {A}}$ obtained from $\mathbb {S}^2$ by blowing up two fixed points of f to the universal covering space of $\overline {\mathcal {A}}$, has a unique rotation number. Moreover, we find the differential of such a distortion element in the group of diffeomorphisms of the 2-sphere at each fixed point up to conjugacy.
We propose a deep reinforcement learning (RL) framework designed to optimize the hedging of specific, user-defined risk factors—referred to as targeted risks—in financial instruments affected by multiple sources of uncertainty. Our methodology uses Shapley value decompositions to establish source of risk grouping’s contribution to the projected contract cash flows, providing a clear attribution of the profit and loss to distinct risk categories. Leveraging this decomposition, we apply deep RL to hedge only the targeted risks, while leaving non-targeted risks mostly unaffected. In addition, we introduce a joint neural network architecture in which the agent network utilizes risk estimates from a risk measurement neural network to stabilize the hedging strategy, taking into account local risk dynamics. Numerical experiments show that our approach outperforms traditional methods, such as delta hedging and traditional deep hedging, significantly reducing targeted risks in variable annuities while maintaining flexibility for broader applications.
Older adults (≥65) often receive antibiotics in emergency departments (ED), where guideline concordance is low with both overuse and underuse; whether community disadvantage drives these patterns is unknown.
Methods:
We analyzed electronic health records from 1,318,281 ED encounters among 790,562 adults ≥65 (2015–2024). Outcomes were guideline concordance and components (overuse, underuse). To address omitted variables and reverse causality, we used two-stage instrumental-variable models with Social Vulnerability Index (SVI) and Social Deprivation Index (SDI) as exposures, instrumented by maximum state Earned Income Tax Credit, adjusting for patient, facility, state, and time covariates.
Results:
16.8% of encounters were non-concordant (overuse 9.5%; underuse 7.2%). Concordance improved to 83.8% in 2024. In IV models, each 10-point increase in SVI reduced concordance by 6.37 percentage points (pp) (SE 0.69) and each 10-point increase in SDI by 1.84 pp (SE .20; P < .0005). Declines reflected higher underuse (+0.43 pp per 10-point SVI; +0.12 pp per 10-point SDI) with less overuse (−0.10 and −0.30 pp). Concordance was higher for Black (+12.90 pp vs White) and Medicaid-insured patients (+5.40 pp vs commercial). Overuse was higher in rural (+7.90 pp vs metropolitan) and academic EDs (+5.00 pp vs non-academic), whereas underuse was more common in metropolitan (+42.50 pp) and non-academic EDs (+32.70 pp). Spatial analyses found high deprivation/low concordance in the South and low deprivation/high concordance in the Midwest.
Conclusions:
Community disadvantage may causally predict lower guideline-concordant antibiotic prescribing for older adults, primarily via underuse. Stewardship should address underuse and overuse and prioritize disadvantaged regions where gaps are greatest.
We investigate the developmental consequences of slave-raiding in Eastern Europe, the largest source of slaves in the early modern world after West Africa. Drawing on a wide-ranging new dataset, we estimate that at least five million people were captured from hundreds of locations across Eastern Europe between the fifteenth and eighteenth centuries. We hypothesize that, over time, raids encouraged an economically advantageous process of defensive state-building linked to raided societies’ resistance to and lack of integration into the slave trade. Using difference-in-differences and instrumental variables strategies, we find that exposure to raids is positively associated with long-run urban growth and related indicators of demographic and commercial development. Consistent with our posited mechanism, raided areas constructed more robust defensive infrastructures and attained higher levels of military, administrative, and fiscal capacity. Our findings suggest that the structure of slave production conditions its developmental legacies, cautioning against drawing generalizations from the African context.
This paper examines how tourism served as a vehicle for informal political propaganda in postwar Taiwan under Guomindang (GMD) rule. Following the Second World War, when the GMD began governing Taiwan, the government recognized tourism’s potential for ideological projection and national legitimation. Through analysis of tourism promotional materials, policy documents, and news reports from Taiwan, Hong Kong, and Southeast Asia, this paper demonstrates how Taiwan deliberately positioned itself as the authentic guardian of ‘Cultural China’ within a competitive regional context. The GMD government strategically deployed Chinese cultural traditions and landmarks as tourism attractions to establish Taiwan’s cultural legitimacy, particularly targeting overseas Chinese communities through ‘returning home tourism’ initiatives that framed Taiwan as the authentic homeland for all ethnic Chinese. Significantly, while Hong Kong promoted itself under the banner ‘The Orient is Hong Kong’ primarily to Western tourists, Taiwan’s dual strategy sought to attract both international visitors interested in experiencing ‘mysterious China’ and overseas Chinese through tourism experiences that showcased ‘Free China’ or ‘Cultural China’. This approach constituted a systematic attempt to legitimize Taiwan’s claim to represent China proper, even as its formal diplomatic position deteriorated in the 1970s. The paper argues that Taiwan’s tourism strategy represented a deliberate political calculation that transcended economic objectives, transforming cultural tourism into a powerful tool for asserting sovereignty and maintaining international relevance despite growing diplomatic isolation.
The black soldier fly (BSF) (Hermetia illucens) has gained global economic relevance as a sustainable resource for animal feed, organic waste bioconversion, and the production of nutrient-rich frass for agricultural use. Its ability to convert low-value waste streams into high-value proteins, lipids, and fertilisers makes BSF a key component of emerging circular-economy models. However, the influence of vegetable and fruit waste (VFW) substrates on insect performance, nutrient composition, frass quality, and economic efficiency remains poorly defined. This study evaluated five substrate levels obtained by mixing laying hen feed with VFW at 0%, 25%, 50%, 75%, and 100%, assessing their effects on the growth performance, body measurements, chemical composition, frass characteristics, and economic traits of BSF larvae and prepupae. The results showed that up to 75% VFW can be used to rear BSF up to 23 days of age without compromising growth traits. Substrate reduction ranged from 67.2% to 89.4%, and larval-to-prepupal conversion increased with feed intake. VFW level significantly affected larval and prepupal nutrient profiles, including dry matter, crude protein, ether extract, nitrogen-free extract, and chitin. Frass from the 100% VFW substrate exhibited the highest nutrient concentration, although this inclusion level impaired feed conversion due to elevated fibre content. Economic analysis indicated that using VFW can reduce substrate costs without negatively affecting revenue. Overall, a VFW inclusion level of up to 75% is recommended as the optimal balance between insect growth efficiency, nutrient recycling, and frass fertilising potential.
A coupled computational-fluid-dynamics/finite-element methodology is implemented to investigate the free aerodynamic separation of clusters of equally sized spheres arranged in regular configurations in Mach-20 flow, representing an idealized meteoroid-fragmentation scenario. The regular nature of the initial agglomeration geometries – touching sphere pairs, tetrahedral four-sphere arrangements and face-centred-cubic 13-sphere configurations – allows a systematic exploration of both individual sphere motions and bulk cluster dynamics as the initial orientation is varied. For sphere pairs, a stable lifting configuration arises when the spheres are in contact in a skewed configuration, a phenomenon that can also emerge in the more populous clusters. In the tetrahedral survey, comprising 38 initial orientations, shock surfing of downstream bodies is found to play a significant role in driving the separation dynamics. Despite substantial variations in detailed sphere motions with initial orientation, the trajectory type and final lateral velocity collapse reasonably well with the initial polar angle of the sphere within the cluster. Indices describing the bluntness and asymmetry of the initial configuration are introduced and correlate well with the collective cluster dynamics, though not always in an intuitive way. For the 13-sphere clusters, the dependency of individual sphere lateral velocities follows a similar trend with initial polar angle to the four-sphere case, suggesting that a simplified separation model may be possible for such configurations. The influence of the initial cluster bluntness on the bulk dynamics is somewhat reduced, however, indicating a tendency towards more homogeneous separation as the cluster population is increased.
We study private equity involvement (or lack thereof) in the long-term care (LTC) sector and its recent developments in the United States, Ireland and Poland. Based on the similarities and differences across these countries’ LTC systems, which can be treated as ideal types of the variety in typical models of LTC systems, we develop a systematic approach to the analysis of private equity engagement in the sector. Specifically, we define the comparison criteria as follows: the debates about the role and place of private equity in LTC; the extent of private equity investments in LTC; the reasons for private equity entry into the LTC sector; the business strategies of private equity firms; the regulations relative to private equity in LTC. Our case study comparison demonstrates that policy responses to population aging and care needs are deeply political processes, leading to a variety of solutions shaped by institutional legacies, cultural contexts, and the power dynamics between states, markets, and civil society.
