Drawing on a wide variety of Chinese-language publications and in-depth interviews with high-school students, Mobilising China's One-Child Generation provides systematic evidence of the spread of martial logic and techniques into Chinese schools. The book explores how China has implemented Patriotic Education and National Defence Education programmes to foster love for the nation and the Party-state, mobilise the population to fight modern wars in the information age, and encourage youth to join the army. It studies how these programmes present the tropes of war and the military to youth, and how they are related to shifting constructions of gender and the national collectivity. It also documents students' varied perceptions–and notably contestations–of this militarised ethos, complicating our understanding of popular nationalism and militarisation processes in this authoritarian global power.
Groups of people in pain evoke our empathic reactions. Yet how does one empathize with a group? Here, we aim to identify psychological mechanisms that underlie empathic reactions to groups. We theorize that because empathy is an egocentric process routed through the self, people are strongly attuned to the impact on each individual, and less so to the number of individuals affected. In five pre-registered experiments, involving different types of stimuli and valences of the outcomes, we repeatedly find that participants' level of empathy depends on the pain experienced by each individual, but not on the number of individuals in the group. The experiments support our hypothesis. They also add to alternative explanations such as psychophysical numbing and strategic regulation of negative emotions, providing valuable insights into the phenomenon of scope insensitivity. The findings also bear implications for the ongoing debate on the role of empathy in public policy decisions.
Combining textual analysis, cultural contextualization, and the history of ideas, this essay excavates the complex “literal sense” of Emma Lazarus’s iconic sonnet, “The New Colossus.” Beginning with the deliberate misreading of the statue’s intended and acknowledged signification and noting the poem’s network of contrarieties, the essay dwells on the contrast between the “wretched refuse” on Ward’s Island and decadent Gilded Age exhibition where the poem was first read; it goes on to argue that the poem disables the connection between progress and poverty, reinvigorates the rhetoric of asylum, points to the Hebraic roots of American history, and reimagines American modernity as a benign merging of contrarieties.

The late 8th century BCE lmlk stamp seal impressions on jar handles are among the most distinctive epigraphic findings in Judah. Currently, they comprise more than two thousand provenanced items from throughout the Judahite territory. While three of the four words engraved below the word lmlk, “(belonging) to the king,” refer to well-known Judahite cities—Hebron, Ziph, and Socoh—the fourth—mmšt— remains incomprehensible since it was first sighted in 1868. In this study, I argue that mmšt is not the name of a city but the expression “from (the?) maś’ēt”—masoretized מִמַּשְׂאֵת—spelled without the aleph. The maś’ēt was a huge and unique ad hoc collection of agricultural products initiated by King Hezekiah as part of his preparations for the anticipated invasion of the Assyrian army following his rebellion. These products were subsequently distributed in jars, whose handles were stamped with the inscription “(belonging) to the king – from (the?) maś’ēt.”
Description of many-electron systems with a fractional electron number (Ntot) and fractional spin (Mtot) is of great importance in physical chemistry, solid-state physics, and materials science. In this Letter, we provide an exact description of the zero-temperature ensemble ground state of a general, finite, many-electron system and characterize the dependence of the energy and the spin-densities on both Ntot and Mtot, when the total spin is at its equilibrium value. We generalize the piecewise-linearity principle and the flat-plane condition and determine which pure states contribute to the ground-state ensemble. We find a new derivative discontinuity, which manifests for spin variation at a constant Ntot, as a jump in the Kohn–Sham potential. We identify a previously unknown degeneracy of the ground state, such that the total energy and density are unique, but the spin-densities are not. Our findings serve as a basis for development of advanced approximations in density functional theory and other many-electron methods.
BACKGROUND: Enterococcal meningitis in children is rare, and its clinical presentation, laboratory characteristics and outcomes are not well defined. METHODS: We conducted a retrospective analysis of Enterococcal meningitis cases during 2002-2023 at our tertiary center. RESULTS: We identified 10 cases in children aged 2 weeks to 15 years (median age: 8 months). Seven children were males and 9 had comorbidities, including a ventriculoperitoneal shunt in 5 children. All children with shunt infections presented with nonspecific signs and symptoms. While 8 children presented with fever, only 3 had signs of meningeal irritation and altered consciousness. Cerebrospinal fluid pleocytosis was evident in almost all children with a median of 173 cells/mL. Nine cases were due to Enterococcus faecalis, and 1 case was due to E. faecium. All 5 children with ventriculoperitoneal shunt underwent shunt removal and replacement. All children recovered without documented sequelae. CONCLUSIONS: Enterococcal meningitis is rare, especially in healthy neonates. It typically occurs following neurosurgical interventions and may only present with fever and shunt malfunction, without overt meningeal signs and with mild inflammation. The prognosis is favorable.
Abstract The use of alternative nutritional sources is an important topic for animal production such as poultry. This study examined the effect of replacing soybean meal with sunflower leaf meal in the diet of laying shaver brown pullets. A total of 30 laying birds were assigned to three treatments of 0% (as control group), 10% and 15% MSFLM inclusion. Four eggs per replicate were randomly taken for three consecutive days at two weeks interval for five times, and 18 weeks individuals were selected after 40 days of experimental time. External parameters of the eggs (egg weight, egg length, egg breadth and egg shape index, shell thickness), and body parameters (Final body weight, weight gain), feed intake and hen day production were measured. For egg length, egg breadth and shell thickness showed significant difference (p
In the early 20th century, the figures of both the peasant woman and the “New Woman” caught the attention of Chinese writers. While the “New Woman” has been the subject of considerable scholarship, the representation of peasant women has not received much scholarly attention. This essay examines the peasant woman as represented in modern Chinese literature to complement the existing understanding of Chinese modernity. It focuses on the rural girl student, as she signifies the clash of two worlds: the rural family as her point of provenance and the modern school as her entry into the urban. Relying on Xiao Hong’s short story “Hands” in the context of historical accounts, I argue that hygiene becomes a type of biopower that punishes the rural girl student for her class origin and racializes her as a barbarian, the process capturing a rural-urban divide. The modern school that expels the protagonist, Wang Yaming, is not an institution that promotes upward mobility but a tool to perpetuate class privileges. Although the narrator shows occasional sympathy with Wang Yaming, under the influence of class difference female solidarity is not achieved.

Ice-binding proteins (IBPs) are expressed in various organisms for several functions, such as protecting them from freezing and freeze injuries. Via adsorption on ice surfaces, IBPs depress ice growth and recrystallization and affect nucleation and ice shaping. IBPs have shown promise in mitigating ice growth under moderate supercooling conditions, but their functionality under cryogenic conditions has been less explored. In this study, we investigate the impact of two types of antifreeze proteins (AFPs): type III AFP from fish and a hyperactive AFP from an insect, the Tenebrio molitor AFP, in vitrified dimethylsulfoxide (DMSO) solutions. We report that these AFPs depress devitrification at −80 °C. Furthermore, in cases where devitrification does occur, AFPs depress ice recrystallization during the warming stage. The data directly demonstrate that AFPs are active at temperatures below the regime of homogeneous nucleation. This research paves the way for exploring AFPs as potential enhancers of cryopreservation techniques, minimizing ice-growth-related damage, and promoting advancements in this vital field.
A novel method is presented for fabricating 3D-printed Cr3+-doped α-Al2O3 complex structures, known as Ruby, using digital light processing (DLP) 3D printing and sol-gel reactions based on solutions only. The aqueous printing solution comprises aluminum and chromium chloride as the sol-gel precursor and acrylic acid (AA) as the polymerizable component. After photopolymerization, aging, and sintering at 1150°C, structures shrink up to 28±7%, achieving a final printing resolution of 55.7±0.7 μm, surpassing the nominal printer’s resolution of 200 μm. Characterization includes X-ray diffraction, scanning electron microscopy, UV-Vis, and fluorescence measurements, revealing crystalline Cr:α-Al2O3 composition emitting at 693 nm. The structures exhibit maximum compression stress of 89±3 MPa and microhardness of 340-500 HV, showcasing potential applications in thermal insulation, jewelry, and mechanical uses.
This article analyzes Israel’s food security in comparison to other developed countries, using multiple indicators divided into four sections: food availability, food affordability, food quality and safety, and natural resources and resilience. Overall, the state of food security in Israel is better than in most countries, but the threats to food security arising from the triple risk of climate change, international conflicts, and disruptions in global supply chains, require better preparation for the future. Israel’s population growth and the slowdown in the growth rate of its agricultural production, as well as the short-term political desire to reduce prices, are leading the country to increasingly rely on food imports. Such imports expose Israel to even greater global risks, and require the formulation of a risk-management strategy that will balance local production and imports. The global triple risk to food security is currently exacerbated for Israel by the risk of shortage of labor due to the security situation, making this risk-management strategy even more necessary. This calls for the establishment of a governmental authority to oversee the formulation of a long-term food-security strategy, to break it down into feasible objectives and policy measures, and to supervise their implementation. Most importantly, in order to maintain and perhaps even enhance the productive capacity of the agricultural sector, the government must reinstall trust between farmers and the state by establishing a stable long-term policy environment.
Eastern Boundary Upwelling Systems (EBUSs) host equatorward wind-driven near-surface currents overlying poleward subsurface undercurrents. Various previous theories for these undercurrents have emphasized the role of poleward alongshore pressure gradient forces (APF). Energetic mesoscale variability may also serve to accelerate undercurrents via mesoscale stirring of the potential vorticity gradient imposed by the continental slope. However, it remains unclear whether this eddy rectification mechanism contributes substantially to driving poleward undercurrents in EBUS. This study isolates the influence of eddy rectification on undercurrents via a suite of idealized simulations forced either by alongshore winds, with or without an APF, or by randomly-generated mesoscale eddies. It is found that the simulations develop undercurrents with strengths comparable to those found in nature in both wind-forced and randomly forced experiments. Analysis of the momentum budget reveals that the along-isobath undercurrent flow is accelerated by isopycnal advective eddy momentum fluxes and the APF, and retarded by frictional drag. The undercurrent acceleration may manifest as eddy momentum fluxes or as topographic form stress depending on the coordinate system used to compute the momentum budget, which reconciles these findings with previous work that linked eddy acceleration of the undercurrent to topographic form stress. The leading-order momentum balance motivates a scaling for the strength of the undercurrent that explains most of the variance across the simulations. These findings indicate that eddy rectification is of comparable importance to the APF in driving poleward undercurrents in EBUSs, and motivate further work to diagnose this effect in high-resolution models and observations, and to parameterize it in coarse-resolution ocean/climate models.
