This study investigated the caregiving capacity of older Chinese carers and discussed whether the Chinese government needs to offer more support to them. In-depth interviews were conducted with forty older respondents aged sixty years or over caring for frail or sick family members. It was found that most respondents demonstrated firm traditional Chinese values by treating relatives bound by blood or marriage as family members and exhibiting a strong obligation towards them. However, the older carers bore a considerable burden and suffered from deteriorating physical and mental health. The Chinese government needs to introduce a nationwide policy for carers, defining its main support and providing clear guidelines for the local government to tackle the caregiving pressures of older carers. Moreover, the concept of ‘common prosperity’ can be adopted as an empowerment strategy by encouraging poor older carers to seek external support without feeling ashamed or dependent on others.

This article contributes to the empirical and theoretical discourse on the ‘stability–instability paradox’, the idea that while possessing nuclear weapons deters cataclysmic all-out war, it simultaneously increases the likelihood of low-level conflict between nuclear dyads. It critiques the paradox’s dominant interpretation (red-line model), which places undue confidence in the nuclear stalemate – premised on mutually assured destruction – to prevent unintentional nuclear engagement and reduce the perceived risks associated with military actions that fall below the nuclear threshold. Recent scholarship has inadequately examined the unintentional consequences of the paradox in conflicts below the nuclear threshold, particularly those relating to the potential for aggression to escalate uncontrollably. The article employs empirically grounded fictional scenarios to illustrate and critically evaluate, rather than predict, the assumptions underpinning the red-line model of the stability–instability paradox in the context of future artificial intelligence (AI)-enabled warfare. It posits that the strategic cap purportedly offered by a nuclear stalemate is illusory and that low-level military aggression between nuclear-armed states increases the risk of unintentional nuclear detonation.

We study the global well-posedness and uniform boundedness of a two-dimensional reaction–advection–diffusion system with nonlinear advection. This strongly coupled system of nonlinear partial differential equations represents the continuum of a 2D lattice model designed to describe residential burglary, where each location is characterised by a tractability value that varies in both space and time. We show that the model with sublinear advection enhancement is globally well-posed, with a unique solution that is classical and uniformly bounded in time. Our results provide valuable insights into the development of urban crime models with nonlinear advection enhancements, making them suitable for broader applications, including nonlocal or heterogeneous near-repeat victimisation effects.

The present study drew on data provided by 179 clergymen and 226 clergywomen to discuss the psychological type and temperaments profile of stipendiary parochial clergy serving in The Episcopal Church (USA) and to set this profile alongside 591 clergymen and 486 clergywomen serving in the Church of England. The data indicated a similar profile for Anglican clergy on both sides of the Atlantic, with preferences for introversion, intuition, feeling and judging. In terms of temperament, in the USA 41% of clergymen were SJ, 38% NF, 17% NT and 4% SP; 43% of clergywomen were NF, 41% SJ, 13% NT and 2% SP.

Transmission electron microscopy-energy dispersive X-ray analysis (TEM-EDX) represents an effective tool for determining the stoichiometric composition of clay minerals, but the methodology is often hampered by analytical difficulties. Studies of beam-sensitive minerals, such as smectites, are associated with low count intensities and dynamic loss of cations (e.g. K+, Na+, and Al3+), which can lead to erroneous quantifications of composition. After exploring how to minimize cation migration by reducing the beam current density to <5 pA cm–2, the most reliable and consistent compositions were determined using 1 μm2 area measurements of particles acquired in normal TEM mode where the electron beam was parallel, the degree of specimen damage was at its minimum and good acquisition intensities (>10,000 cps) were acquired. Based on 528 TEM-EDX area analyses, the composition of Wyoming montmorillonites (SWy-1, SWy-2, and SWy-3) was studied in their natural and Ca-saturated states from thin (<50 nm thick) particle aggregates lying on lacey carbon films. Overall, the TEM-EDX results confirmed the heterogeneous charge distributions of montmorillonite at the particle and sample levels. The average composition per formula unit of SWy-1 to -3 was determined as: (Na0.12Ca0.04Mg0.03K0.02)(Si3.91Al0.09)(Al1.57Mg0.27Fe0.19)2.03 O10(OH)2 · nH2O, where the tetrahedral and octahedral layer charges are –0.09 and –0.19 per O10(OH)2, respectively, and the total layer charge ranges from –0.25 to –0.30 per O10(OH)2 (mean of –0.28). This study demonstrates how TEM-EDX can provide new insight into the natural heterogeneities of smectite chemistry as long as adequate calibration and specimen damage control procedures are implemented.

Testing prototypes with users is essential when developing new products. This qualitative study examines and organizes users’ (children) feedback on physical toy prototypes at various fidelity levels; the data collected comes from a multidisciplinary design studio class tasked with developing wooden toys for the company PlanToys. In this research, we use an organizational framework to categorize stakeholders’ feedback, which includes affirmative feedback, convergent critical feedback, and divergent critical feedback. In our analysis, the children’s feedback was compared by prototype fidelity in terms of both form and function, as well as by the feedback categorization. Findings suggest that form fidelity may bias children toward giving more divergent feedback, that function fidelity may have little impact on feedback given, that children tend to give more types of feedback on lower fidelity than higher fidelity models, and that play value, form, interaction, and function were the highest reported categories of feedback. Based on our observations, we encourage toy designers to be aware of their goals for testing with children before beginning to prototype. This paper is a resource for designers to understand how to prototype for children, as well as resource for researchers studying how specific end users influence the product design process.

In this article, we demystify the South African Defence Force’s 32 Battalion and de-exceptionalize the apartheid military by connecting it to other colonial military communities, and apartheid governance more broadly. Drawing on oral history, autoethnography, and archival documents, we demonstrate the highly unequal, yet mutual, reliance of white authorities and elite Black women in the haphazard and improvised nature of apartheid military rule. Most women arrived at the unit's base, Buffalo, as Angolan refugees, where white military authorities fixated on their domestic and family lives. We examine the practical workings of military rule by considering three nodes of social surveillance and control. Elite Black women, known as “block leaders,” served as intermediaries, actively participating in the mechanics of military rule while also using their position to advocate for their community. Finally, we consider the ingrained violent patriarchal nature of life in the community by highlighting the nature of women's precariousness and labor.

We report on the pore size distribution and water retention of Beacon sandstone from Antarctica that harbours a cryptoendolithic community, predominantly lichens, just below the surface. We measured the pore size distribution, drying time and equilibrium relative humidity of sandstone samples that were colonized by lichens. The incremental pore volume distribution peaks at ~10 μm radius, but ~20% of the pore volume occurs for a radius < 0.02 μm. Water from snowmelt fills ~20% of the total pore volume. It takes ~4–5 days of evaporation to lose 90% of the water. As the rock loses water, the equilibrium relative humidity remains at 99% until an appreciable amount (80–90%) of the pore water is lost, after which the equilibrium relative humidity starts to decrease. The relative humidity remains at > 80% (68 h) long after the water content falls to < 98% (19 h) - the point at which liquid water is estimated no longer to be present. Lichens can remain active in air with high relative humidity (> 80%). Thus, the pore size distribution of the sandstone may play a role in explaining why lichens dominate these sandstones.

Climate change is a global challenge to ecosystem services, altering crop yields and food security worldwide. In the context of climate change, Onobrychis viciifolia Scop. (sainfoin) can offer a multitude of ecosystem services conferred by its multifaceted beneficial properties. We reviewed the morphological, biochemical and physiological responses to environmental stressors of O. viciifolia, summarized its ecological, agronomic, nutritional and biological interests, and we discussed its use under climate change. Onobrychis viciifolia is a hemicryptophyte forage legume adapted to arid and semiarid regions by evolving a diverse array of protective mechanisms against abiotic stressors at morphological, biochemical and physiological levels. In the present scenario of climate change, O. viciifolia has desirable forage characteristics such as high nutritive value, high voluntary intake and palatability to grazing animals, leading to satisfying animal performance for milk, meat, honey and wool production. Recent studies suggest that O. viciifolia has several highly beneficial phytochemical properties including condensed tannins and polyphenol content, which have been demonstrated to have anthelmintic activities, enhance protein utilization, and prevent bloating. In addition, O. viciifolia also has the potential to reduce greenhouse gas emissions and sequestrate atmospheric carbon and nitrogen into the soil. Ethnobotanical investigations show that O. viciifolia possesses antimicrobial, antiseptic and vulnerary activities. This review could be helpful for understanding of O. viciifolia characteristics, interests and uses, thus promoting its reasonable cultivation under a changing climate.

This paper explores understudied issues surrounding accessions to shareholder and partnership agreements: the process by which such accessions take effect; the survival of equities following an accession; and the enforcement of a condition for incoming shareholders to have to execute and deliver a deed of accession. Accessions happen extremely often in modern commercial life, which renders surprising the dearth of academic and judicial discussion, but more disconcerting is the unsettledness of some of the complex issues implicated. The repurposing of unilateral contracts to explain how deeds of accession operate is not fully tested in English law; the conception of partial novation as adumbrated in Unitech Global Ltd v Deutsche Bank AG, which is not even law – much less bad law – has already generated academic controversy; and the enforcement of a condition precedent, in the form of prior accession to a shareholder agreement, for registration of membership in a company interacts in an uncertain way with the Companies Act 2006, lending impetus to the adoption of new methods for attaining relief.

Weighted lottery proposals give guidance in rescue dilemma situations by balancing the demands of comparative and absolute fairness. While they do not advocate for saving the greater number outright, they are responsive to absolute fairness insofar as they show a certain sensitivity to the numbers involved. In this paper we investigate what criterion of absolute fairness we should demand weighted lotteries to fulfill. We do so by way of critically examining what is probably the most sophisticated weighted lottery on the market: Gerard Vong's Exclusive Composition-Sensitive (EXCS) lottery. We find that both the standard that seems most common in the debate, and a different standard Vong uses to criticize Jens Timmermann's Individualist Lottery are in contradiction to basic demands placed upon weighted lotteries and are therefore unsuitable as necessary conditions for absolute fairness. We instead propose a purely gradual understanding of absolute fairness.

Standard accounts of what makes exploitation wrong ground its wrong in distributive unfairness: when A exploits B he wrongs her by taking a greater share of the benefits from their interaction than he ought. I argue that this standard account does not succeed; distributive unfairness is neither the sole, nor the primary wrong of exploitation. I assume that distributive unfairness is pro tanto wrong. However, I argue that in situations where transactors’ consent to a transaction is morally valid, it is also morally transformative and overrides distributive unfairness’s pro tanto wrong. Thus, wrongful exploitation requires morally invalid consent.

Recently, the field of robotics development and control has been advancing rapidly. Even though humans effortlessly manipulate everyday objects, enabling robots to interact with human-made objects in real-world environments remains a challenge despite years of dedicated research. For example, typing on a keyboard requires adapting to various external conditions, such as the size and position of the keyboard, and demands high accuracy from a robot to be able to use it properly. This paper introduces a novel hierarchical reinforcement learning algorithm based on the Deep Deterministic Policy Gradient (DDPG) algorithm to address the dual-arm robot typing problem. In this regard, the proposed algorithm employs a Convolutional Auto-Encoder (CAE) to deal with the associated complexities of continuous state and action spaces at the first stage, and then a DDPG algorithm serves as a strategy controller for the typing problem. Using a dual-arm humanoid robot, we have extensively evaluated our proposed algorithm in simulation and real-world experiments. The results showcase the high efficiency of our approach, boasting an average success rate of 96.14% in simulations and 92.2% in real-world settings. Furthermore, we demonstrate that our proposed algorithm outperforms DDPG and Deep Q-Learning, two frequently employed algorithms in robotic applications.

Obesity is a chronic, complex and multi-factorial condition with an increasing prevalence worldwide. Irregular eating schedules might be a contributing factor to these numbers through the dysregulation of the circadian system. Time-restricted eating (TRE), an approach that limits eating windows, has been studied as a strategy to treat obesity, aligning eating occasions with metabolic circadian rhythms. This review aims to provide an overview of the impact of TRE protocols on metabolic, inflammatory, oxidative stress and circadian rhythm biomarkers in people with overweight or obesity. Most studies report significant weight loss following TRE protocols. While glucose levels decreased in nearly all TRE interventions, only a few studies demonstrated statistically significant differences when compared to the control groups. The findings for c-reactive protein and TNF-α were inconsistent, with limited significant differences. Changes in lipid profile changes were variable and generally did not reach statistical significance. Both 4-hour and 6-hour TRE interventions significantly reduced 8-isoprostane levels. Additionally, TRE significantly altered clock gene expression, as well as that of genes associated with metabolic regulation in subcutaneous adipose tissue. While the evidence is still inconsistent, limiting eating to a consistent daily window of 8 to 12 h can improve insulin sensitivity, reduce blood glucose, cholesterol and triglyceride levels and promote weight loss. These effects are likely attributable to both direct metabolic impacts and indirect benefits from weight loss and improved dietary habits. However, data on circadian, inflammatory and specific metabolic biomarkers remain scarce and occasionally contradictory, highlighting the need for further research on these interventions.

The importance of interactions between child temperament and parenting has been accepted ever since Thomas and Chess (1977) proposed their “goodness-of-fit” construct, but over the last three decades, pertinent research has grown exponentially. Researchers examining child characteristics that can moderate the effects of socialization have tested increasingly complex, nuanced, and sophisticated models, largely inspired by the highly influential frameworks of child plasticity or differential susceptibility (Belsky & Pluess, 2009). Yet, multiple questions remain unsettled. We addressed four such questions as applied to predicting children’s observed disregard for rules at age 4.5 in a study of 200 community families from the US Midwest. (a) We examined children’s observed negative emotionality at 16 months, most commonly seen as a plasticity “trait,” but separating anger and fear proneness, which may differently moderate effects of socialization. (b) We examined two separate aspects of observed parental socialization at age 3, mutually responsive orientation and power assertion. (c) We distinguished analytically diathesis-stress from differential susceptibility. (d) We examined all effects in mother– and father–child relationships. We supported both diathesis-stress and differential susceptibility, depending on the facet of negative emotionality, the aspect of socialization considered, and parental gender, highlighting the nuanced nature of the processes involved.
